Description

Technical Field

[0001] The utility model relates to the technical field of plate and frame filter presses, in particular to an automatic mud dropping device for a plate and frame filter press. Background Art

[0002] A plate and frame filter press is an intermittent solid-liquid separation device consisting of alternating filter plates and filter frames forming a filter chamber. Under pressure, liquid enters the filter chamber, where solid-liquid separation occurs through the filter medium. It offers excellent separation performance, a wide range of applications, and simple operation. It is widely used in the chemical, pharmaceutical, and environmental protection industries for solid-liquid separation of various suspensions, making it an indispensable piece of equipment in industrial production.

[0003] The automatic mud dropping device of the plate and frame filter press is a mechanism that can automatically remove the filter cake. For example, the A-shaped automatic mud dropping mechanism of the double-diaphragm plate and frame filter press uses the frame, vibration frame, membrane plate and other structures, combined with the A-shaped arrangement of the filter cloth and the drive of the vibration motor to achieve rapid and automatic removal of the filter cake, saving mud unloading time and improving work efficiency.

[0004] However, there is no connection between the plates and frames of the traditional plate and frame filter press. When the filter cake between the plates and frames is to be removed, the plates and frames need to be opened one by one and the filter cake between the plates and frames need to be removed in sequence, which greatly increases the mud dragging operation time and thus reduces the solid-liquid separation efficiency. In response to the above problems, the inventors proposed an automatic mud dropping device for a plate and frame filter press to solve the above problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: an automatic mud dropping device for a plate and frame filter press, comprising two side plates, two connecting rods fixedly connected between the two side plates, a number of filter plates arranged between the side plates and the connecting rods, sliders fixedly connected on both sides of the filter plates, slide rails fixedly connected on the tops of the connecting rods, the sliders slidingly clamped on the outer sides of the corresponding slide rails, the sliders being connected by linkage components, vibration components arranged on both sides of the top of the slider, a driving component arranged on one of the side plates, a U-shaped plate fixedly connected between the tops of the two side plates, and a knocking component arranged on the U-shaped plate.

[0007] Preferably, the filter plate includes a mounting frame, which is fixedly connected to the mounting frame corresponding to the slider, and the filter plate is slidably connected to the inside of the mounting frame. The top and bottom ends of the filter plate are movable through the mounting frame, and the side of the rightmost mounting frame close to the threaded rod is set as a sealing surface.

[0008] Preferably, the linkage assembly includes a rotating rod 1 and a rotating rod 2, both of which are rotatably connected to one side of the slider, the middle parts of the rotating rod 1 and the rotating rod 2 are rotatably connected, and the two ends of the adjacent rotating rod 1 and the rotating rod 2 are connected end to end.

[0009] Preferably, the vibration assembly includes a fixed plate, which is fixedly connected to one side of the top of the filter plate, and the bottom end of the fixed plate is fixedly connected to a telescopic rod, and one side of the top of the mounting frame is fixedly connected to a square plate, and the bottom end of the telescopic rod movably extends to the bottom end of the square plate and is fixedly connected to a limiting block, and a spring is provided on the top surface of the square plate and the bottom end of the fixed plate, and the spring is movably sleeved on the outside of the telescopic rod.

[0010] Preferably, the driving assembly includes a threaded rod, which is fixedly connected to one side of the filter plate, and the inner side of the side plate is rotatably connected to gear 1, and gear 1 is threadedly connected to the outer side of the threaded rod. The end of the threaded rod away from the filter plate moves through the corresponding side plate, and a servo motor is fixedly installed on the bottom end of the side plate. The driving end of the servo motor is fixedly connected to gear 2, and gear 1 is meshed with gear 2.

[0011] Preferably, the knocking assembly includes an electric cylinder, which is fixedly installed in the middle of the top of the U-shaped plate.

A push plate is slidably connected between the two guide rods, and the piston rod of the electric cylinder is fixedly connected to the push plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. Through the cooperation between the rotating rod 1 and the rotating rod 2, when the driving assembly drives one filter plate to move horizontally, it can simultaneously drive all the filter plates to move in the same direction, so that the distance between adjacent filter plates changes equidistantly, thereby enabling the filter plates to be quickly opened and closed, facilitating the shedding operation of the filter cake, and further improving work efficiency;

[0014] 2. The push plate is pushed to move vertically along the outside of the guide rod by the extension and retraction of the piston rod of the electric cylinder.

[0023] Example: Figures 1-5As shown, the utility model provides an automatic mud dropping device for a plate and frame filter press, comprising two side plates 1, two connecting rods 2 fixedly connected between the two side plates 1, a plurality of filter plates 3 arranged between the side plates 1 and the connecting rods 2, sliders 4 fixedly connected on both sides of the filter plates 3, slide rails 5 fixedly connected on the tops of the connecting rods 2, the sliders 4 slidingly clamped on the outer sides of the corresponding slide rails 5, the sliders 4 being connected by linkage components 6, vibration components 7 arranged on both sides of the tops of the sliders 4, a driving component 8 arranged on one of the side plates 1, a U-shaped plate 10 fixedly connected between the tops of the two side plates 1, and a knocking component 9 arranged on the U-shaped plate 10.

The filter plate 32 is slidably engaged inside the mounting frame 31 , and the top and bottom ends of the filter plate 32 are movable through the mounting frame 31 .

[0025] By adopting the above technical solution, the installation frame 31 is installed in the filter plate 32 by sliding and snapping. It is convenient to install and disassemble the installation frame 31, and it is convenient for the installation frame 31 to move vertically along the inner side of the filter plate 32. When used in conjunction with the vibration component 7, the filter cake attached to the surface of the filter plate 32 can be quickly removed.

[0026] The linkage assembly 6 includes a rotating rod 1 61 and a rotating rod 2 62. The rotating rod 1 61 and the rotating rod 2 62 are both rotatably connected to one side of the slider 4.

[0027] By adopting the above technical solution, through the cooperation between the rotating rod 1 61 and the rotating rod 2 62, when the filter plate 3 on the far right moves toward the side of the driving component 8, all the filter plates 3 are driven to move in the same direction at the same time, so that a certain gap is formed between adjacent filter plates 3, thereby cooperating with the knocking component 9 to facilitate a one-time desludging operation.

[0028] The vibration assembly 7 includes a fixed plate 71, which is fixedly connected to one side of the top of the filter plate 32. The bottom end of the fixed plate 71 is fixedly connected to a telescopic rod 72. One side of the top of the mounting frame 31 is fixedly connected to a square plate 74.

A spring 73 is provided between the top surface of the square plate 74 and the bottom end of the fixed plate 71. The spring 73 is movably sleeved on the outside of the telescopic rod 72.

[0029] By adopting the above technical solution, when the filter plate 32 moves downward under the push of the knocking assembly 9, it drives the fixed plate 71 and the telescopic rod 72 to move downward and compresses the spring 73. When the thrust of the knocking assembly 9 is quickly removed, the elastic force of the spring 73 is utilized, and the telescopic rod 72 is limited by the limit block 75 to reset the filter plate 32, thereby forming a vertical reciprocating vibration of the filter plate 32, which can shake off the filter cake attached to the surface of the filter plate 32.

The end of the threaded rod 81 away from the filter plate 3 moves through the corresponding side plate 1. A servo motor 83 is fixedly installed at the bottom end of the side plate 1. The driving end of the servo motor 83 is fixedly connected to a gear 2 84, and the gear 1 82 is meshed with the gear 2 84.

[0031] By adopting the above technical solution, the servo motor 83 drives the gear 2 84 to rotate, and the gear 2 84 is engaged with the gear 1 82 to drive the gear 1 82 to rotate, and the filter plate 3 is used to guide the threaded rod 81 and drive the threaded rod 81 to move laterally, thereby realizing the opening and closing operation of the filter plate 3.

[0032] The knocking assembly 9 includes an electric cylinder 91, which is fixedly installed in the middle of the top of the U-shaped plate 10.

A push plate 92 is slidably connected between the two guide rods 93, and the piston rod of the electric cylinder 91 is fixedly connected to the push plate 92.

[0033] By adopting the above technical solution, the push plate 92 is pushed to move vertically along the outer side of the guide rod 93 through the extension and contraction of the piston rod of the electric cylinder 91. When the push plate 92 moves downward, it can press all the filter plates 32 at the same time, thereby realizing the mud dropping operation of all the filter plates 32.

[0034] A side of the rightmost mounting frame 31 close to the threaded rod 81 is configured as a sealing surface.

[0035] By adopting the above technical solution, the side of the rightmost mounting frame 31 close to the threaded rod 81 is set as a sealing surface, and the two ends of the filter plate are sealed in cooperation with the leftmost side plate 1.

[0036] Working principle: When the plate and frame filter press is being desludged, the servo motor 83 drives the gear 2 84 to rotate, and the gear 2 84 is engaged with the gear 1 82, which drives the gear 1 82 to rotate. The filter plate 3 guides the threaded rod 81, and at the same time drives the threaded rod 81 to move horizontally, thereby realizing the opening and closing of the filter plate 3.

[0038] During desludging, the push plate 92 is pushed to move vertically along the outer side of the guide rod 93 by extending and retracting the piston rod of the electric cylinder 91. When the push plate 92 moves downward, it can press all the filter plates 32 at the same time and compress the spring 73. When the thrust of the knocking assembly 9 is quickly removed, the elastic force of the spring 73 is utilized, and the telescopic rod 72 is limited by the limit block 75 to reset the filter plate 32, thereby forming a vertical reciprocating vibration of the filter plate 32, and shaking off the filter cake attached to the surface of the filter plate 32.
