    A tube pressure filter including an inner compartment having an inlet which comprises a substantially annular aperture extending around the lower end of the inner tubular body and debouching into the inner compartment. The substantially annular aperture is constructed and disposed so that, in use, feed material debouching therefrom has an upward component of velocity and is in communication with an ante-chamber into which a mixture to be pressure filtered can be introduced under pressure through a feed conduit, the feed conduit containing or co-operating with a non-return valve so as to prevent the flow back along the feed conduit of feed material to be pressure filtered which is under high pressure.

    专利说明:

    The invention relates to press filters for separating liquids and solids suspended in them, in particular to tubular press filters.
    Known tubular press filter, comprising vertically mounted one in another cylinders, an impermeable elastic sleeve located inside the inner cylinder, a filter element, a discharge device for ejecting the filtrate and a device for displacing the cylinders in the axial direction relative to each other [1].
    The closest to the invention in technical essence and the achieved result is a tubular press filter comprising vertically mounted cylinders in one another, the inner of which is equipped with a filtering element and a filtrate outlet pipe, an impermeable elastic sleeve located between the outer and inner cylinders, feed pipes for the source material and hydraulic fluid, a preliminary chamber with ducts [2].
    A disadvantage of the known device is that it is unable to prevent leakage of the starting material and damage to the impermeable elastic sleeve.
    The purpose of the invention is the prevention of damage to an impermeable elastic sleeve and leakage of the original fibrous and coarse-grained material.
    This is achieved by the fact that the tubular press filter is equipped with a toroidal chamber with an annular, 0 oblique, upwardly directed channel connected to the preliminary chamber by ducts located above it.
    It is advisable to supply the source material supply pipe with a check valve5 nom.
    In FIG. 1 shows a tubular press filter, General view; in FIG. 2 - the lower part of the inner cylinder of the press filter, General view.
    The tubular press filter consists of two vertically mounted cylinders, the inner of which 1 with the upper end part 2 and the lower cover 3. The outer cylinder 4 is equipped with an impermeable elastic sleeve 5, and the inner cylinder 1 is equipped with a filter element 6. Cylinders 1 and 4 are formed with an impermeable with elastic sleeve 5 inside 7 and outside 8, the latter being equipped with a hydraulic fluid supply pipe 9. In the lower part of the inner cylinder 1 there is an internal head 10 welded to it, ring 11 with a compartment 5, body 12, L-image th ring 13, closely adjacent to the ring and the outer head 14 and attached to the inner die 10 with set screws 15, clamping ring 11 between the inner and outer go- TIONs 10, 10 and 14.
    Rings 11 and 13 are expediently made of high-strength metals or synthetic plastic, for example polyurethane.
    A sealing ring 16 is located between the inner head 10 and the ring 15. The preliminary chamber 17 is formed by the inner head 10, the ring 11 and the outer head 14. The feed pipe 18 passes through the 20 inner head 10 so that the feed material flowing through this to the channel, it enters the preliminary chamber 17, from where it flows through the ducts 19 to the toroidal chamber 20 and then to the annular, inclined, 25 upwardly directed channel 21 located above it. The width of the annular gap is 0.7-0.8 mm. A fabric gasket 22 is provided between the external head 14 and the rings 11 and 12. The external head zo 14 is provided with a groove 23, which includes an annular seal, which provides sealing when interacting with the external cylinder 4 and the centering pin forming the bottom 24 of the preliminary camera 35.
    The feed pipe is provided with a threaded nipple 25, to which a check valve 26 is attached, having a hexagonal steel rod. The steel ball 27 is located in the socket 28. The spindle 29 is equipped with stops 30.
    The tubular press filter operates as follows. 45
    The source material through the supply pipe 18 enters the preliminary chamber 17. When the pressure of the source material is close to atmospheric, the steel ball 27 is located in the socket 28. With increasing pressure, the ball 27 rises until it comes into contact with the lower end of the threaded spindle 29 The spindle 29 is provided with stops 30 so that the feed stream is set at the highest position of the ball 27. When the ball 27 is resting in its seat, the column of material is held in the nozzle 18 thus formed hydraulic lock, and leakage through channel 21 does not occur.

    8 a cavity, the latter being provided with a hydraulic fluid supply pipe 9. In the lower part of the inner cylinder 1 an internal head 10 is welded to it, a ring 11 with a slam-shut 12, an L-shaped ring 13 tightly attached to the ring 11, and an external head 14, Attached to the inner head 10 by set screws 15, clamping the ring 11 between the inner and outer heads 10 and 14. Rings And and 13 should be made of high-strength metals or synthetic plastic, for example polyurethane. Between the inner head 10 and the ring 11 is located the sealing ring 16. The pre-chamber 17 is formed by the inner head 10, the ring And and the outer head 14. The feed pipe for the source material 18 passes through the inner head 10 so that the feed material flows through this channel into the a preliminary chamber 17, from where along the ducts 19 - into the toroidal chamber 20 and further into the annular, inclined, upward channel 21, located above it. The width of the annular gap is 0.7-0.8 mm. A fabric gasket 22 is provided between the outer head 14 and the rings I and 12. The outer head 14 is provided with a groove 23, which includes an o-ring seal that seals the interaction with the outer cylinder 4 and the centering pin that forms the bottom 24 of the preliminary chamber 17. The feed pipe of the source material is provided a threaded nipple 25 to which a check valve 26 is attached, having a hexagonal steel rod. Steel shchar 27 is located in the nest 28. The spindle 29 is provided with lugs 30. The tubular press filter works as follows. The feed through feed pipe 18 enters the pre-chamber 17. When the pressure of the source material is close to atmospheric, the steel ball 27 is located in the socket 28. As the pressure increases, the ball 27 rises until it comes into contact with the lower end of the threaded spindle 29 The spindle 29 is provided with stops 30 so that the flow of the feed material is established at the highest position of the ball 27. When the ball 27 is at rest in its nest, the substance column is held in the pipe 18 by the hydraulic lock thus formed. And flowing out through the channel 21 does not occur. Claim 1. A tubular press filter comprising cylinders vertically mounted one to another, the inner of which is provided with a filter element and a filtrate outlet nozzle, an impermeable elastic sleeve placed between the outer and inner cylinders, feed pipes of the source material and hydraulic fluid, a preliminary chamber ducts, characterized in that, in order to prevent damage to the impermeable elastic sleeve and leakage of the original fibrous and coarse-grained material, it provides It is a toroidal camera with an annular ring above it, an inclined, upward channel, and ducts connected to the preliminary chamber. 2.Press filter according to claim 1, that is, so that the supply pipe of the source material is equipped with a check valve.
