Description

Technical Field

[0001] The invention relates to the technical field of filter presses, in particular to a new and efficient filter press. Background Art

[0002] The clean coal separated by the flotation machine is foamy. The solids content of the flotation clean coal foam varies with the various process conditions, generally ranging from 250-400g / L. Therefore, the flotation clean coal foam must be dehydrated to ensure that it meets storage and transportation requirements. Dehydration of the flotation clean coal is generally performed in a filter. The moisture content of the filter cake after filtration and dehydration varies depending on the properties of the clean coal and the performance of the filter, typically ranging from 20% to 30%. If users have higher moisture requirements for the clean coal (such as export coal moisture requirements below 8%) or if the flotation clean coal is shipped separately, the moisture content of the flotation clean coal must be reduced even further. Water is an impurity in coal. Coal with a high moisture content is not suitable for user use and winter transportation, and it increases freight volume and wastes transportation resources. Therefore, the moisture content of the coal products shipped by the coal preparation plant must be minimized.

[0003] The main dehydration equipment in existing coal preparation plants is a quick-opening diaphragm filter press. The moisture content of the flotation clean coal after dehydration is generally around 25%. In order to ensure the moisture content of the final clean coal, it must be reduced to below 20%. By increasing the feeding time, increasing the pressing pressure, adding secondary pressing and other measures, the moisture content was reduced to 24%, but it still could not be reduced below 20%, which is not enough to ensure the moisture content of the final clean coal. By comparing the working principles of the pressure filter and the filter press, comparing the advantages and disadvantages of the two, the filter press is technically modified, absorbing the dehydration principle of the pressure filter and combining it with the high-pressure pressing of the filter press to solve the problem of high moisture content. To this end, the present invention provides a new and efficient filter press. Summary of the Invention

A high-pressure water inlet channel 5 is provided on the side wall of the membrane filter plate 111, and the high-pressure water inlet channel 5 is connected to the interlayer 1111.

[0031] Before operation, filter cloths are sheathed on the surfaces of the membrane filter plate 111 and the solid filter plate 112. The sheathed filter cloths can not only filter out fixed particles in the material, but also enhance the sealing between the adjacent membrane filter plates 111 and the solid filter plates 112. During operation, the filter assembly and the filter cloths located between the compression assembly 4 and the tail plate 7 are compressed by means of the compression assembly 4, and a filter chamber is formed between the filter cloth sheathed on the surface of the compressed membrane filter plate 111 and the filter cloth sheathed on the surface of the solid filter plate 112.

Then the moisture enters the upper water outlet and the lower water outlet through the upper drainage pipe and the lower drainage pipe respectively. Finally, the moisture in the upper water outlet and the lower water outlet is discharged from the filter press through the upper undercurrent pipe 9 and the lower undercurrent pipe 10 respectively, and is collected and reused; the material that has lost moisture gradually solidifies After the material input is completed, the water pressing component 12 is provided to introduce high-pressure water, and the high-pressure water enters the interlayer 1111 inside the diaphragm filter plate 111 through the high-pressure water inlet channel 5. The introduced high-pressure water causes the cavity walls on both sides of the diaphragm filter plate 111 to expand outward, and then the expanded cavity walls of the diaphragm filter plate 111 are used to squeeze and dehydrate the filter cake again. This is the water pressing link; Subsequently, the external high-pressure air pump inputs high-pressure gas to the upper undercurrent pipe 9, and the high-pressure gas passes through the upper water outlet channel 114, the upper drainage channel 119 and the filter cloth in turn, and finally the high-pressure gas enters the filter chamber, and the introduced high-pressure gas passes from the top of the filter cake to the bottom of the filter cake. After the gas takes away part of the moisture in the filter cake, it passes through the filter cloth, the lower drainage channel 1110 and the lower water outlet channel 115 in turn, and finally the high-pressure gas is discharged from the filter press through the lower underflow pipe 10. This is the angle blowing link; after completion, the staff opens the valve on the central feed pipe 8, and changes the central feed pipe 8 and the feed channel 113 into a backwash channel, and introduces high-pressure gas into the feed channel 113 and the central feed pipe 8 through the backwash pipe 6, thereby blowing the coal slurry in the feed channel 113, the central feed pipe 8 and other pipes back into the material barrel; after the backwash is completed, the compression assembly 4 is depressurized, and the unloading device pulls apart the filter plates to complete the dehydration operation.

[0032] Furthermore, the clamping assembly 4 includes a hydraulic push rod 41 fixedly mounted on the side wall of the vertical plate 1, the telescopic end of the hydraulic push rod 41 is fixedly connected to a push plate 42, and the back-blowing pipe 6 is connected to the back of the push plate 42, and the push plate 42 is provided with an air intake channel 43 at one end away from the hydraulic push rod 41, and the air intake channel 43 corresponds to the feed channel 113. The hydraulic push rod 41 pushes the push plate 42 to move, and with the help of the push plate 42, the filter assembly and filter cloth located between the push plate 42 and the tail plate 7 are compressed, and a filter chamber is formed between the filter cloth sleeved on the surface of the compressed diaphragm filter plate 111 and the filter cloth sleeved on the surface of the solid filter plate 112.

[0033] Furthermore, the water pressing assembly 12 includes a high-pressure water pump 1 121 and a high-pressure water pump 2 122. A water pipe 123 is connected between the high-pressure water pump 1 121 and the high-pressure water pump 2 122. A plurality of groups of diverter hoses 124 are connected to the water pipe 123 at equal intervals, and the diverter hose 124 is connected to the high-pressure water inlet channel 5 on the side away from the water pipe 123. The material that loses moisture gradually solidifies into a filter cake. After the material input is completed, the high-pressure water pump 12 is set. 1 introduces high-pressure water, which is set to enter the interlayer 1111 inside the diaphragm filter plate 111 through the water pipe 123, the diversion hose 124 and the high-pressure water inlet channel 5 in sequence. The introduced high-pressure water causes the cavity walls on both sides of the diaphragm filter plate 111 to expand outward, and then uses the expanded cavity walls of the diaphragm filter plate 111 to squeeze and dehydrate the filter cake again. This is the water squeezing step. After the water squeezing is completed, the set high-pressure water pump 122 will pump out the high-pressure water in the interlayer 1111.

[0034] Furthermore, the sliding assembly 116 includes a mounting frame 1161 fixedly connected to the side wall of the membrane filter plate 111 , and a pulley 1162 is rotatably connected to the bottom of the mounting frame 1161 .

[0036] Working principle: Before operation, filter cloth is placed on the surface of the membrane filter plate 111 and the solid filter plate 112. The filter cloth can not only filter out the fixed particles in the material, but also enhance the sealing between the adjacent membrane filter plates 111 and solid filter plates 112;

[0037] During operation, the hydraulic push rod 41 pushes the push plate 42 to move, and the filter assembly and filter cloth between the push plate 42 and the tail plate 7 are pressed by the push plate 42, and a filter chamber is formed between the filter cloth sleeved on the surface of the compressed diaphragm filter plate 111 and the filter cloth sleeved on the surface of the solid filter plate 112; then the external material pump conveys the material into the diaphragm filter plate 111 and the solid filter plate 112 through the central feed pipe 8, and the material passes through the central feed pipe 8, the feed channel 113 on the side wall of the tail plate 7, and the feed channel 113 on the side wall of the solid filter plate 112 in turn. And the feed channel 113 on the diaphragm filter plate 111, and finally the material enters each filter chamber, wherein the solid particles in the material are intercepted by the filter cloth and then retained in the filter chamber, while the moisture in the material passes through the filter cloth and enters the inside of the groove 117 and the groove 2 118, and then the moisture passes through the upper drainage pipe and the lower drainage pipe respectively into the upper water outlet hole and the lower water outlet hole, and finally the moisture in the upper water outlet hole and the lower water outlet hole is discharged from the filter press through the upper underflow pipe 9 and the lower underflow pipe 10 respectively, and is collected and reused;

[0038] The material that has lost moisture gradually solidifies into a filter cake. After the material input is completed, the high-pressure water pump 121 is set to introduce high-pressure water. The high-pressure water is sequentially passed through the water pipe 123, the diversion hose 124 and the high-pressure water inlet channel 5 into the interlayer 1111 inside the diaphragm filter plate 111. The introduced high-pressure water causes the cavity walls on both sides of the diaphragm filter plate 111 to expand outward, and then the expanded cavity walls of the diaphragm filter plate 111 are used to squeeze and dehydrate the filter cake again. After completion, the high-pressure water pump 122 is set to press the inner layer 1111 into the filter cake. The high-pressure water is pumped away, which is the water squeezing step; then, the external high-pressure air pump inputs high-pressure gas into the upper underflow pipe 9, and the high-pressure gas passes through the upper water outlet channel 114, the upper drainage channel 119 and the filter cloth in sequence, and finally the high-pressure gas enters the filter chamber. The introduced high-pressure gas passes from the top of the filter cake to the bottom of the filter cake, and the high-pressure gas takes away part of the moisture in the filter cake and passes through the filter cloth, the lower drainage channel 1110 and the lower water outlet channel 115 in sequence. Finally, the high-pressure gas is discharged from the filter press through the lower underflow pipe 10, which is the corner blowing step;

[0039] After completion, the staff opens the valve on the central feed pipe 8, changes the central feed pipe 8 and the feed channel 113 into a back-blowing channel, and introduces high-pressure gas into the back-blowing pipe 6 through an external high-pressure air pump. The high-pressure gas enters the feed channel 113 and the central feed pipe 8 through the air inlet channel 43, thereby blowing the coal slurry in the feed channel 113, the central feed pipe 8 and other pipes back into the material barrel; after the back-blowing is completed, the compression component 4 is depressurized, and the unloading device pulls apart the filter plates to complete the dehydration operation; the present application passes the high-pressure gas through the filter cake, and the flow takes away part of the moisture. By adding an angle blowing link, the high-pressure gas flow dehydration principle of the pressurized filter is brought into the traditional filter press. This combines the advantages of the pressurized filter with the advantages of the traditional filter press, which not only solves the problems of high energy consumption and large investment of the pressurized filter, but also solves the problem of high moisture in the traditional filter press.
