Description

Technical Field

[0001] The utility model relates to the technical field of plate and frame filter presses, and particularly relates to a plate and frame filter press convenient for collecting filter cakes. Background Art

[0002] Traditional plate and frame filter presses usually consist of a main machine, filter plates, filter frames, a hydraulic system, an automatic vibration device, etc. During the working process, a liquid mixture is pumped into the filter press. After a period of filtration, solid particles gradually accumulate on the filter cloth to form filter cakes. However, traditional plate and frame filter presses have the following problems in filter cake collection: firstly, the collection of filter cakes is not convenient enough, requiring manual operation or the use of auxiliary equipment, which increases the operation difficulty and cost; secondly, the filter cakes are prone to scatter during the collection process, resulting in environmental pollution and material waste.

[0003] In the prior art, a patent with the publication number CN220478229U provides a plate and frame filter press convenient for collecting filter cakes, which includes a frame, a filter press body, a guide plate, a collection box, and a flapping member. The filter press body is arranged on the frame; the guide plate is connected to the frame and is located below the filter press body. The guide plate gradually slopes downward from one side of the filter press body to the other side to guide the filter cakes; the collection box is arranged at the outlet end of the guide plate for accommodating the filter cakes; the flapping member is arranged on the frame and is located below the guide plate for flapping the guide plate to make the filter cakes slide into the collection box. The plate and frame filter press convenient for collecting filter cakes provided by this utility model can, under the guidance of the guide plate and in cooperation with the flapping of the flapping member on the guide plate, make the filter cakes enter the collection box, avoiding manual collection of filter cakes by workers and saving labor.

[0004] Although the above patent solves the problem that the collection of filter cakes in the past was not convenient enough, however, the method of using the flapping of the guide plate to make the filter cakes slide into the collection box cannot accurately control the quantity of the collected filter cakes, resulting in the inability of relevant personnel to effectively record the filtration base quantity generated by the equipment operation. Therefore, the utility model provides a plate and frame filter press convenient for collecting filter cakes. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a plate and frame filter press convenient for collecting filter cakes, which solves the problem that in the past, when collecting filter cakes of a plate and frame filter press, the quantity of the collected filter cakes could not be accurately controlled, resulting in the inability of relevant personnel to effectively record the filtration base quantity generated by the equipment operation.

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions: A plate and frame filter press convenient for collecting filter cakes includes a filter press body, and a collection mechanism is installed on the filter press body for collecting the filter cakes generated inside the plate and frame filter press. The collection mechanism includes:

[0007] A receiving component is arranged inside the middle part of the filter press body, and includes an iron core fixedly installed on the inner wall of one side of the filter press body. A magnetic plate is connected to the lower part of the iron core. On the other side of the iron core, a telescopic rod is fixedly installed on the filter press body, and a fixed plate is fixedly connected to the lower part of the telescopic rod. An elastic cloth bag is bonded between the magnetic plate and the fixed plate;

[0008] An energizing component is arranged on one side of the filter press body and is used to energize the outside of the iron core to generate magnetic attraction force;

[0009] A collection box is arranged at the bottom of the filter press body and is used to store the filter cake that slides off the elastic cloth bag.

[0010] Preferably, the telescopic rod includes a sleeve fixedly installed on the inner wall of one side of the filter press body. A sliding column is slidably installed in the lower part of the sleeve, and a tension spring is installed between the top of the sliding column and the inner top wall of the sleeve. The bottom of the sliding column is connected to the fixed plate.

[0011] Preferably, the energizing component includes a power supply box fixedly installed on the outer wall of one side of the filter press body. A first electrical connection piece and a second electrical connection piece are installed on the outer wall of the filter press body on the same side as the power supply box, and the power supply box is electrically connected to the first electrical connection piece. A coil is wound around the outer wall of the iron core, and the coil is electrically connected to the second electrical connection piece.

[0012] Preferably, a cross bar is vertically slidably installed on the outer wall of one side of the filter press body, and the cross bar is fixed to the fixed plate.

[0015] Advantageous effects

[0016] The utility model provides a plate and frame filter press which is convenient for collecting filter cake. Compared with the prior art, the following advantageous effects are achieved:

[0017] (1) The plate and frame filter press that is convenient for collecting filter cakes uses an elastic cloth bag to preliminarily collect the filter cakes discharged by the equipment. As the amount of filter cakes on the elastic cloth bag increases, its own weight will also increase, which will then produce a stretching effect on the telescopic rod on one side. The stretching spring begins to lengthen under the tensile force, causing the sliding column and the fixed plate to move downward, which in turn drives the conductive rod to move downward. After the first power-on plate and the second power-on plate lose the connection with the conductive rod, the power is disconnected, so that no current flows into the external coil of the iron core, the iron core loses its magnetism and then disconnects from the magnetic plate at the lower end, and the filter cake on the elastic cloth bag naturally slides into the collection box below, making it convenient for relevant personnel to record the filtration base amount.

[0018] (2) The plate and frame filter press is convenient for collecting filter cakes. The filter cakes are pre-collected by designing elastic cloth bags. After being discharged, the filter cakes fall into the elastic cloth bags below the equipment. The elastic cloth bags provide cushioning for the filter cakes, thus preventing the filter cakes from being broken due to excessive impact force when falling. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The receiving assembly 21 is arranged on the inner side of the middle part of the filter press body 1, and includes an iron core 211 fixedly installed on the inner wall of one side of the filter press body 1, and a magnetic plate 212 is connected to the lower part of the iron core 211. A telescopic rod 213 is fixedly installed on the filter press body 1 at the other side of the iron core 211, and a fixed plate 214 is fixedly connected to the lower part of the telescopic rod 213. An elastic cloth bag 215 is bonded between the magnetic plate 212 and the fixed plate 214;

[0027] The power supply component 22 is arranged on one side of the filter press body 1 and is used to supply power to the outside of the iron core 211 to generate magnetic attraction;

[0028] The collecting box 23 is disposed at the bottom of the filter press body 1 and is used to store the filter cake that slides off the elastic cloth bag 215 .

[0029] In this embodiment, the telescopic rod 213 includes a sleeve 2131 fixedly mounted on the inner wall of one side of the filter press body 1, a sliding column 2132 is slidably mounted at the lower part of the sleeve 2131, and a tension spring 2133 is installed between the top of the sliding column 2132 and the inner top wall of the sleeve 2131, and the bottom of the sliding column 2132 is connected to the fixed plate 214.

[0030] In this embodiment, the power supply component 22 includes a power supply box 221 fixedly mounted on the outer wall of one side of the filter press body 1, and the filter press body 1 is provided with a first power connection piece 222 and a second power connection piece 223 on the outer wall on the same side as the power supply box 221, and the power supply box 221 is electrically connected to the first power connection piece 222, and the outer wall of the iron core 211 is wound with a coil 224, and the coil 224 is electrically connected to the second power connection piece 223, and the outer wall of the filter press body 1 is vertically connected to the outer wall of the filter press body 1. A cross bar 225 is installed on the straight slide, and the cross bar 225 is fixed to the fixed plate 214. When the conductive rod 226 moves downward, the first power contact piece 222 and the second power contact piece 223 lose the connection with the conductive rod 226, and the power is disconnected, so that no current flows into the external coil 224 of the iron core 211, the iron core 211 loses its magnetism and is disconnected from the magnetic plate 212 at the lower end, and the filter cake on the elastic cloth bag 215 naturally slides into the collection box 23 below.

[0031] In this embodiment, a conductive rod 226 is fixedly mounted on the end of the crossbar 225 , and the conductive rod 226 , the first power contact plate 222 , and the second power contact plate 223 are located on the same vertical line.

[0032] In this embodiment, the power supply box 221, the first power connection piece 222, the second power connection piece 223, the conductive rod 226 and the coil 224 form a complete closed circuit, and then the current inside the power supply box 221 is input into the coil 224.

[0033] Meanwhile, the content not described in detail in this specification belongs to the prior art well known to those skilled in the art.

[0034] During operation, start the equipment switch of the plate and frame filter press. The suspension to be processed is input into the filter chamber through the feed pipeline. Under the action of the pressing device, the plates and frames are tightly pressed together, and the filter cloth covers the plates and frames to form a filtering medium. Next, the substances in the suspension are forced through the filter cloth into the filter chamber at a certain pressure. The filter cloth has a certain pore size, which can prevent solid particles from passing through while allowing liquid to pass through. As the suspension enters, the solid particles on the filter cloth gradually accumulate and are washed by the filtrate to form a filter cake. After the filter cake is discharged, it falls into the elastic cloth bag 215 below the equipment, and the elastic cloth bag 215 provides buffering for the filter cake. As more and more filter cake accumulates on the elastic cloth bag 215, its own weight will also increase, and then it will exert a tensile effect on the telescopic rod 213 on one side. The tension spring 2133 starts to stretch under the tensile force, causing the sliding column 2132 and the fixed plate 214 to move downward, and then driving the conductive rod 226 to move downward. After the first power connection piece 222 and the second power connection piece 223 lose the connection of the conductive rod 226, the power supply is disconnected, so that no current flows into the external coil 224 of the iron core 211, and the iron core 211 loses magnetism and then disconnects from the magnetic plate 212 at the lower end. The filter cake on the elastic cloth bag 215 naturally slides down into the collection box 23 below.
