Description

Technical Field

[0001] The utility model belongs to the technical field of filter press equipment, and in particular relates to a high-pressure gas-water separation device for a filter press. Background Art

[0002] The filter press is currently the most advanced solid-liquid separation equipment in the mineral dehydration process. Under the strong positive pressure, the slurry is squeezed into the filter chamber, the solid mineral particles are intercepted by the filter cloth, and the liquid is discharged through the filter cloth. The high-energy filter cloth and filter plate are arranged in the order of filter plate-filter cloth-filter cloth-filter plate to form several filter chambers. After the filter plate is pressed, the slurry enters the two filter cloths of the filter chamber from the feed channel, and the solid particles of the slurry form a filter cake. The filtrate passes through the filter cloth and is discharged from the liquid collection channel below the filter plate; after the filter plates are separated from each other, the filter cake falls due to gravity, thereby achieving the purpose of solid-liquid separation.

[0003] The filter press currently used in the mineral processing industry works by pressing the filter plate, feeding and filtering, squeezing and drying for dehydration, reverse filtrate piping, re-squeezing and drying for dehydration, pulling open the filter plate for unloading, etc. In the two links of reverse filtrate piping and squeezing and drying for dehydration, the compressed air for air drying and blowing is mixed with the filtrate water from squeezing and dehydration for drainage, causing the discharged filtrate water and compressed air to spray and splash, affecting the work site environment, which is not conducive to clean and civilized production and increases the workload of workers in cleaning the site. Utility Model Content

[0004] The utility model provides a high-pressure air-water separation device for a filter press, which is used to solve the problem that the filtrate water discharged in the pressing, drying and dehydrating link mentioned in the background technology is mixed with compressed air and causes the filtrate water to spray and splash when discharged.

[0005] To this end, the utility model adopts the following technical solutions:

[0006] A high-pressure gas-water separation device for a filter press comprises a sealed box, the left side of the box is a gas-liquid separation zone, and the right side is a liquid inlet buffer zone; a vertical box partition is connected between the gas-liquid separation zone and the liquid inlet buffer zone, a gap is left between the lower end of the box partition and the bottom of the box, and the other three sides of the box partition are sealed and connected to the box; a water inlet is provided on the box at the top of the liquid inlet buffer zone, an exhaust port is provided on the box at the top of the gas-liquid separation zone, and a drain port is provided on the box at the bottom;

[0007] A plurality of horizontal partitions arranged at intervals and in a staggered manner are arranged in the liquid inlet buffer area; a plurality of vertical partitions arranged at intervals and in a staggered manner are arranged in the gas-liquid separation area.

[0008] Furthermore, the transverse partitions are arranged at intervals along the left and right sides in the liquid inlet buffer zone.

[0009] Furthermore, the vertical partitions are also connected to vertical partition diagonal braces.

[0010] Furthermore, a vertical partition cover plate is fixed on the top of the plurality of vertical partition plates for blocking, and the vertical partition cover plate seals the upper space of the vertical partition plates.

[0011] Furthermore, a water retaining plate is fixed to the upper part of the vertical partition cover plate.

[0012] The design principle of the utility model is as follows: after the compressed air and filtrate water enter the box, they first pass through the four horizontal partitions of the right box to buffer and release the pressure, thereby reducing the pressure of the compressed air and filtrate water. After the filtrate water with compressed air enters the left box, it passes through three staggered vertical partitions, and the pressure of the filtrate water is greatly reduced. A vertical partition cover is provided above the vertical partition to prevent the compressed air from moving upward and taking away part of the filtrate water when the filtrate water mixed with compressed air passes through the vertical partition and spraying out from the exhaust port. After the compressed air and filtrate water pass through the buffering effect of several horizontal partitions and vertical partitions, the pressure has been greatly reduced, and then the filtrate water is discharged from the drain port below the box. In order to ensure the separation of compressed gas and filtrate water, a water baffle is provided below the exhaust port to block the moisture carried in the compressed air. Finally, the compressed air is discharged from the upper exhaust port, thereby achieving the purpose of gas-water separation.

[0013] The beneficial effects of the utility model are:

[0014] The utility model installs a high-pressure gas-water separator device on the emptying pipe of the filter press, and has multiple horizontal and vertical partitions inside. The filtrate water mixed with compressed gas discharged from the working process of the filter press is buffered multiple times through the horizontal and vertical partitions, and the filtrate water is separated from the compressed gas, and then discharged from the bottom drain port and the upper exhaust port respectively, so as to solve the problem that the filtrate water discharged in the pressing, drying and dehydrating link of the filter press is mixed with the compressed air and causes the filtrate water to spray and splash when discharged.
