Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment equipment, and in particular to a sewage treatment filter press equipment. Background Art

[0002] Filter pressing is a commonly used solid-liquid separation process. It uses a specific filter medium to force the liquid to seep through the medium under a certain pressure, while blocking the solid particles on the surface of the medium, thereby achieving effective separation of solids and liquids. In the field of sewage treatment, filter press is a commonly used filter pressing equipment. Its structure consists of filter plates and filter frames with filter cloths arranged alternately. These filter plates and filter frames together constitute multiple filter chambers. Under the action of pressure, the liquid to be treated flows through the filter cloth into the filter chamber, and is discharged from the drain pipe after filtration, while the solid particles are captured by the filter cloth to form a filter cake that remains on the medium.

[0003] After the solid-liquid separation is completed, the filter plate and filter frame need to be separated one by one through the driving mechanism so that the filter cake can fall from between them. For the tightly attached filter cake, the filter plate and filter frame need to be shaken to accelerate the falling of the filter cake.

[0004] At present, the unloading process of filter cake mainly relies on the single drive spreading method, that is, separating and shaking the filter plates or filter frames one by one to promote the rapid shedding of filter cake.

[0038] A mounting seat 15 is provided on one of the limit plates 13, the driving assembly 7 is arranged on the mounting seat 15, the swinging assembly 8 is installed on one of the limit plates 13, and the swinging assembly 8 is respectively connected to one of the support rods 12 and the driving assembly 7, a collecting trough 16 is provided between the first support plate 1 and the second support plate 2, a discharge port is provided at the bottom of the collecting trough 16, the crushing assembly 9 is arranged adjacent to the discharge port, and a conveyor belt 20 is provided below the discharge port.

[0039] It should be noted that the driving assembly 7 described in this embodiment can drive the swing assembly 8 to start, and with the cooperation of the swing assembly 8, drive the corresponding support rod 12 to swing, and through the cooperation of the connecting assembly 5, drive other support rods 12 to swing, thereby driving the filter plate 3 and the filter frame 4 to swing back and forth to speed up the falling speed of the filter cake.

[0040] Furthermore, a collecting box (not shown in the figure) is provided on one side of the conveyor belt 20 to collect the crushed filter cakes in a unified manner.

[0041] In one embodiment of the present application, Figure 7 As shown, the connection assembly 5 may include two connection shafts 50 and a connection sheet 51 , wherein the two connection shafts 50 are respectively arranged on the side walls of the adjacent filter plates 3 and filter frames 4 , and the connection sheet 51 is sleeved on the two connection shafts 50 .

[0042] It should be noted that in order to prevent the connecting piece 51 from falling off the connecting shaft 50, see Figure 7 A limiting groove 510 is provided on the inner wall of the connecting piece 51 , and a limiting ring 21 is provided on the connecting shaft 50 , and the limiting ring 21 is slidably connected to the limiting groove 510 .

[0043] In the embodiment of the present application, the adjacent filter plates 3 and filter frames 4 can be connected together through the cooperation of the connecting shaft 50 and the connecting sheet 51, so that the multiple filter plates 3 and the multiple filter frames 4 can be quickly separated.

[0044] In one embodiment of the present application, Figure 2 As shown, the driving assembly 7 may include a motor 70 , a driving shaft 71 and a rotating rod 72 , wherein the motor 70 is disposed on the mounting seat 15 , the driving shaft 71 is connected to the output end of the motor 70 , and the rotating rod 72 is disposed on the driving shaft 71 .

[0045] In the embodiment of the present application, when the motor 70 is started, the driving shaft 71 cooperates to drive the rotating rod 72 to rotate, and the rotating rod 72 can control the operation of the swing assembly 8.

[0046] In one embodiment of the present application, Figure 2 As shown, the swing assembly 8 may include a rotating shaft 80, a swing plate 81, a sliding rod 82, an incomplete gear 83 and a complete gear 84, wherein the rotating shaft 80 is rotatably set on the side wall of one of the limit plates 13, the swing plate 81 is set on the rotating shaft 80, and a second sliding groove 810 is penetrated through the swing plate 81, the sliding rod 82 is slidably connected to the second sliding groove 810, and one end of the sliding rod 82 is connected to the rotating rod 72, the incomplete gear 83 is set on the rotating shaft 80, and the complete gear 84 is set on one of the support rods 12, and there is a meshing relationship between the incomplete gear 83 and the complete gear 84.

[0047] It should be noted that the complete gear 84 is arranged on the middle support rod 12. When the filter plate 3 and the filter frame 4 are separated from each other, the middle support rod 12 will drive the complete gear 84 to move, so that the complete gear 84 moves to mesh with the incomplete gear 83.

[0048] In the embodiment of the present application, when the rotating rod 72 rotates, it can drive the sliding rod 82 to rotate. At the same time, the sliding rod 82 slides in the second slide groove 810, thereby driving the swing plate 81 to swing back and forth, and through the cooperation of the incomplete gear 83 and the complete gear 84, it drives the support rod 12 connected thereto to rotate forward and reverse by a certain angle, that is, drives the corresponding filter plate 3 or filter frame 4 to swing left and right. At this time, with the cooperation of the connecting component 5, it can also drive other filter plates 3 and filter frames 4 to swing, thereby accelerating the shedding speed of the filter cake.

[0049] In one embodiment of the present application, Figure 6 As shown, the crushing assembly 9 may include two crushing shafts 90 and two crushing rollers 91 , wherein the two crushing shafts 90 are both arranged inside the collecting tank 16 , and the two crushing rollers 91 are respectively arranged on the corresponding crushing shafts 90 .

[0050] It should be noted that the two crushing rollers 91 described in this embodiment are arranged near the discharge port, and the crushing shaft 90 is connected to an external driving mechanism. The driving mechanism can drive the two crushing rollers 91 to rotate in opposite directions, thereby crushing large pieces of filter cake into small pieces, which is convenient for collection and can reduce the impact force on the conveyor belt 20, thereby extending the service life of the conveyor belt 20.

[0051] In one embodiment of the present application, Figure 3As shown, the clamping mechanism 6 may include a driving member 60, a clamping plate 61 and a plurality of springs 62, wherein the driving member 60 is mounted on the side wall of the second support plate 2, the clamping plate 61 is arranged at the output end of the driving member 60, a plurality of first grooves 610 are provided on one side of the clamping plate 61 adjacent to the filter plate 3, a plurality of springs 62 are respectively arranged in the corresponding first grooves 610, and the springs 62 are connected to the adjacent filter plates 3.

[0052] It should be noted that the driving member 60 described in this embodiment can be a hydraulic rod or a pneumatic rod, and the driving member 60 can drive the clamping plate 61 to move toward the filter plate 3, so that multiple filter plates 3 and multiple filter frames 4 can fit tightly.

[0053] Furthermore, when filtering sewage, multiple filter plates 3 and multiple filter frames 4 fit tightly. At this time, the spring 62 is hidden inside the first groove 610. When the filtering is completed, the telescopic rod of the driving member 60 is controlled to retract. At this time, the driving member 60 drives the clamping plate 61 to move away from the filter plate 3, and drives the filter plate 3 connected thereto to move. With the cooperation of the connecting component 5, the multiple filter plates 3 and the filter frames 4 are separated from each other, thereby facilitating the falling of the filter cake.

[0054] In one embodiment of the present application, Figure 5 As shown, a second groove 17 is provided on one side of the first support plate 1 adjacent to the second support plate 2 , a positioning rod 18 is provided inside the second groove 17 , and the positioning rod 18 and the adjacent connecting shaft 50 are connected via a connecting sheet 51 .

[0055] In the embodiment of the present application, the positioning rod 18 can limit the filter plate 3 adjacent to the thrust plate 19 to ensure that the filter plate 3 adjacent to the thrust plate 19 is connected to the first support plate 1 .

[0056] Specifically, when filtering sewage, relevant personnel control the drive member 60 to start, and the drive member 60 drives the clamping plate 61 to move in the direction of the filter plate 3, so that multiple filter plates 3 and filter frames 4 are tightly fitted to form a filter chamber. At this time, relevant personnel pump the sewage into the filter chamber through the water inlet pipe 11. After filtering through multiple layers of filter cloth, the filtered sewage is discharged through the drain pipe. At this time, larger particles in the sewage are retained on the filter cloth, and finally form a filter cake.

[0057] When the filter cake accumulates to a certain thickness, the drainage volume will be significantly reduced. In order to improve the filtration efficiency of sewage, the relevant personnel can control the telescopic rod of the driving member 60 to retract. Figure 1, the driving member 60 drives the rightmost filter plate 3 to move to the right, and with the cooperation of the connecting assembly 5, pulls the other filter plates 3 and the filter frame 4 to move, and finally separates the multiple filter plates 3 and the filter frame 4 from each other, and part of the filter cakes will fall off automatically. At the same time, the support rod 12 drives the complete gear 84 to move to mesh with the incomplete gear 83, and then the relevant personnel control the motor 70 to start, the motor 70 drives the driving shaft 71 to rotate, and the driving shaft 71 drives the rotating rod 72 to rotate. With the cooperation of the sliding rod 82, the swing plate 81 and the incomplete gear 83 are driven to swing back and forth, and finally the complete gear 84 and the supporting rod 12 connected thereto are driven to rotate forward and reverse back and forth, that is, the corresponding filter plate 3 and the filter frame 4 are driven to swing left and right. At the same time, with the cooperation of the connecting assembly 5, other filter plates 3 or filter frames 4 are driven to swing, thereby accelerating the falling speed of the filter cake.

[0058] The filter cake will directly fall into the collecting tank 16, and after being crushed by the two crushing rollers 91, it will fall onto the conveyor belt 20, thereby effectively alleviating the impact force on the conveyor belt 20 and reducing the wear on the conveyor belt 20. The crushed filter cake has a small volume, which is convenient for storage and transportation.

[0059] In summary, the sewage treatment filter press equipment of the embodiment of the present application can drive multiple filter plates or filter frames to swing at the same time, which accelerates the falling speed of the filter cake and improves the overall efficiency of unloading. At the same time, it can also crush large pieces of filter cake, effectively alleviating the impact force on the conveyor belt 20, thereby extending the service life of the conveyor belt 20.
