Abstract
Description
Technical Field
[0001] The utility model mainly relates to the technical field of filter press equipment, and particularly relates to a filter cloth cleaning mechanism for a filter press. Background Art
[0002] The filter press equipment utilizes filter plates and a thrust plate to apply a certain pressure to the external material to be filter-pressed, so that the liquid seeps out. Generally, filter cloth is covered on the filter plates to assist the liquid seepage. It is a commonly used solid-liquid separation device. After long-term use, the filter cloth is prone to blockage of the filter cloth holes. If effective cleaning cannot be carried out, over time, due to the blockage of the filter cloth holes, it is easy to cause the accumulation of the mixture, thereby affecting the filtering effect of the filter press equipment. The traditional method of cleaning the filter cloth is generally to remove the filter cloth from the filter plate and then uniformly clean it through external equipment, which requires adding the process of filter cloth disassembly and handling, and the work efficiency is low.
[0003] The prior art cleans the filter cloth and the filter plates one by one through a reciprocating cleaning mechanism, without the need to disassemble and transport the filter cloth, and the work efficiency is high. However, during the reciprocating movement of the cleaning mechanism, its water outlet also moves synchronously, and multiple filter cloths cannot be cleaned simultaneously, reducing the cleaning efficiency of the cleaning mechanism. Moreover, the cleaning mechanism cannot independently control the cleaning of some filter cloths, and the filter cloths that have been cleaned sufficiently will be repeatedly cleaned, resulting in waste. Content of the Utility Model
[0004] Aiming at the above problems existing in the prior art, the purpose of the utility model is to provide a filter cloth cleaning mechanism for a filter press, which can clean multiple filter cloths simultaneously and can independently control some filter cloths.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A filter cloth cleaning mechanism for a filter press includes a height adjustment structure located on the filter pressing path of the filter press. The number of the height adjustment structures is two groups. Any one group of the height adjustment structures includes a support member that moves and adjusts along the height direction. A plurality of filter cloth cleaning structures are arranged between the tops of the two support members. Any one filter cloth cleaning structure is connected with a water guide pipe, and the other end of the water guide pipe is connected with a water inlet structure.
[0006] Preferably, any one group of the height adjustment structures further includes two stepper screw motors. The output end of any one stepper screw motor is threadedly provided with an adjustment screw rod. Any one support member is fixed on the two adjustment screw rods of the same group, and the support member is controlled to move along the height direction through the stepper screw motor and the adjustment screw rod.
[0007] Preferably, any set of filter cloth cleaning structures includes a sliding rod, a water spray pipe, and a filter plate. The sliding rod is mounted on two support members. The water spray pipe is fixedly connected to the sliding rod. The filter plate is fixedly connected to the water spray pipe. A second water inlet is formed on one side of the water spray pipe, and the second water inlet is connected to a water guide pipe. A number of second water outlets are formed on the outer wall of the water spray pipe. The water spray pipe is located above the filter plate, and the filter cloth is evenly cleaned through the sliding rod, the water spray pipe, and the filter plate.
[0008] Further, grooves are formed inwardly at both sides of the filter plate, and pulleys are fixed on the grooves. The pulleys are located above the filter press and slide along the filtering path, so as to avoid abrasion caused by direct frictional contact between the filter plate and the top of the filter press.
[0009] Preferably, the water inlet structure includes a water inlet pipe and a shunt pipe. A number of pneumatic valves are arranged between the water inlet pipe and the shunt pipe. A first water inlet is formed at one end of the water inlet pipe. A number of blind plates are arranged axially on the shunt pipe. A number of first water outlets are formed axially on the shunt pipe. The number of the first water outlets is the same as that of the water guide pipes and they are connected in one-to-one correspondence. The flow of water in the shunt pipe is segmented and isolated and controlled through the pneumatic valves and the blind plates.
[0010] Compared with the prior art, the present utility model has the following beneficial effects:
[0011] The filter cloth is stored through a number of filter cloth cleaning structures mounted on the filter press, and the number of filter cloth cleaning structures is independently connected to a number of water guide pipes for independent water spraying and cleaning. The simultaneous cleaning of multiple filter cloths has high working efficiency. And by connecting a number of water guide pipes to the water inlet structure, the pneumatic valves and blind plates of the water inlet structure are used to segmentally isolate and switch the water flow, and the cleaning of some filter cloths is independently controlled, so as to avoid waste caused by repeated cleaning of the filter cloths that have been sufficiently cleaned.

[0021] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.
[0022] The technical solution of the present utility model will be further described below in conjunction with the drawings and through specific implementation manners.
[0023] The embodiment of the present utility model provides a filter cloth cleaning mechanism for a filter press, which can adjust the distance between the filter plate and the thrust plate without changing the stroke of the filter plate cylinder.
[0024] As Figures 1 to 4 shown, a filter cloth cleaning mechanism for a filter press includes a height adjustment structure 3 located on the filter press path formed between the filter press push plate and the thrust plate of the filter press 1. The number of the height adjustment structures 3 is two groups and they are respectively located on the outer walls of the front and rear sides of the filter press 1. Any one group of the height adjustment structures 3 includes a support member 33 that moves and adjusts along the height direction. Fifteen filter cloth cleaning structures 2 are arranged between the tops of the two support members 33. Any one filter cloth cleaning structure 2 is connected with a water guide pipe 5. The number of the water guide pipes 5 is fifteen, which is the same as the number of the filter cloth cleaning structures 2 and is in one-to-one correspondence and communication. The other end of the water guide pipe 5 is connected with a water inlet structure 4.
[0025] Any one group of the height adjustment structures 3 further includes two stepping screw motors 31. Any one group of the stepping screw motors 31 is fixed on the outer wall of the filter press 1. The output end of the stepping screw motor 31 is provided with an adjusting screw 32 in a threaded manner. Any one support member 33 is a rectangular pipe, and the support member 33 is fixed on the two adjusting screws 32 of the same group, and the support member 33 is perpendicular to the adjusting screw 32.
[0026] Any one set of filter cloth cleaning structures 2 includes a slide bar 21, a water spray pipe 22, and a filter plate 23. The slide bar 21 is mounted on two support members 33. The water spray pipe 22 is fixedly connected to the slide bar 21 through a connecting plate. The filter plate 23 is also fixedly connected to the water spray pipe 22 through a connecting plate. A second water inlet 221 is formed at the front end of the water spray pipe 22. The second water inlet 221 is connected to a water guide pipe 5. A plurality of second water outlets 222 are formed on the outer walls on the left and right sides of the water spray pipe 22. The water spray pipe 22 is located above the filter plate 23. The water flow in the water spray pipe 22 is sprayed onto the surfaces of the filter plates 23 on the left and right sides along the second water outlets 222. Grooves are formed inwardly at both sides of the filter plate 23. Pulley 24 is fixed on the upper surface of the groove. The pulley 24 is located above the filter press 1 and slides along the filtering path, so as to prevent the filter plate 23 from directly rubbing against the top of the filter press during the filtering process, resulting in wear.
[0027] The water inlet structure 4 includes a water inlet pipe 41 and a shunt pipe 44. Five pneumatic valves 43 are arranged between the water inlet pipe 41 and the shunt pipe 44. The right end of the water inlet pipe 41 is sealed and a first water inlet 42 is formed at the left end. Four blind plates 45 are arranged axially on the shunt pipe 44. The blind plate 45, also known as a flange cover, is a commonly used sealing part of a water pipe. The blind plate 45 divides the shunt pipe 44 into five independent spaces, which are in one-to-one correspondence and communication with the five pneumatic valves 43. Three first water outlets 46 are formed axially on the surface of each section of the shunt pipe 44. The total number of the first water outlets 46 is fifteen, which is the same as the number of the water guide pipes 5 and is in one-to-one correspondence and communication with them. Each pneumatic valve 43 controls the water flow conduction of three water guide pipes 5.
[0028] The implementation principle of the embodiment of the present application is as follows: When this mechanism is in use, all pneumatic valves 43 are first started. Water flows from an external water source into the first water inlet 42, and then successively passes through the first water outlets 46, the water guide pipes 5, and the second water inlet 221 and flows into the water spray pipe 22. Water is sprayed from a plurality of second water outlets 222 on the surface of the water spray pipe 22 onto the filter plates 23 on its left and right sides to synchronously clean the filter cloths covered on the surfaces of the plurality of filter plates 23, with high working efficiency. After the three filter plates 23 and the filter cloths controlled by the same pneumatic valve 43 are all cleaned sufficiently, the corresponding pneumatic valve 43 is closed to perform grouped and independent control of the filter cloth cleaning, so as to avoid waste caused by repeated cleaning.
[0029] It will be apparent to those skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, and that the present application can be implemented in other specific forms without departing from the basic characteristics of the present application. Therefore, in all respects, the embodiments should be regarded as exemplary and non-limiting. The scope of the present application is defined by the appended claims rather than the above description.
