Description

Technical Field

[0001] This utility model relates to the field of plate and frame filter press technology, specifically to a high-efficiency plate and frame filter press dewatering machine. Background Technology

[0002] Plate and frame filter presses were the first machines used in chemical dewatering. They have advantages such as high filtration driving force, high solid content in filter cake, clear filtrate, high solid recovery rate, and low consumption of conditioning chemicals. They are still widely used in some wastewater treatment plants.

[0003] When the filter cake is discharged from the existing plate and frame filter press, some filter cake debris may accumulate in the filter cloth pores, causing blockage. To prevent this from clogging the filter cloth during subsequent use, the filter cloth is usually unblocked. Common unblocking methods include sweeping, rinsing, backwashing, and vibration. However, these methods have the following problems: rinsing and backwashing are the most effective, but they produce a large amount of rinsing water that mixes with the filter cake debris, forming new wastewater that needs to be treated again, thus increasing costs. While vibration and sweeping do not require water and avoid water pollution, sweeping can easily cause wear between the filter cloth and the filter cloth, affecting its service life. Vibration can cause collisions between the plate and frame and the supporting guide structure, resulting in wear and tear. Furthermore, vibration may be transmitted to other components, causing wear and damage. Significant wear and tear can also affect the machine's service life. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a high-efficiency plate and frame filter press dewatering machine to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency plate and frame filter press dewatering machine, comprising a frame, with supports connected to both sides of the top of the frame, and a servo motor installed on one side of the support. The output end of the servo motor is connected to a ball screw. A slide rail is connected to the top of the support, and a support platform is connected between the slide rail and the ball screw. A servo cylinder and a slider are respectively provided on the top of the support platform, and a push plate assembly is provided at the output end of the servo cylinder, with a sliding groove at the bottom of the push plate assembly.

[0006] By adopting the above technical solution, the output end of the servo motor drives the ball screw to rotate, and the slide rail reduces friction and provides anti-rotation guidance, causing the support platform to move laterally, thereby driving the pusher plate assembly to move laterally. During the separation of the plate and frame assembly, the servo motor stops to avoid the subsequent lateral reciprocating motion of the plate and frame assembly from colliding with other plate and frame assemblies. Then, the output end of the servo electric cylinder drives the pusher plate assembly to move laterally reciprocating for a period of time. During this period, the slider and slide groove guide the pusher plate assembly to reduce friction. The inertia generated by its reciprocating lateral motion shakes off the residue adhering to the plate and frame assembly. After that, the servo motor restarts and works with the pusher plate assembly to make the plate and frame assembly continue to move towards the filter press assembly.

[0007] Furthermore, the support platform is threadedly connected to the ball screw via a ball nut, and the support platform is slidably connected to the slide rail.

[0008] By adopting the above technical solution, the output end of the servo motor drives the ball screw to rotate, and the slide rail reduces friction and provides anti-rotation guidance, so that the support platform moves laterally, thereby driving the push plate assembly to move laterally.

[0009] Furthermore, the push plate assembly is slidably connected to the support platform via a slider and a groove.

[0010] By adopting the above technical solution, the output end of the servo electric cylinder drives the push plate assembly to move laterally and reciprocally for a period of time, during which the slider and the groove guide the push plate assembly to reduce friction.

[0011] Furthermore, both the slider and the groove have a "T" shaped longitudinal section.

[0012] By adopting the above technical solution, the shape of the slider and the groove can limit the push plate assembly, preventing the push plate assembly from falling off when shaking off residue from the plate frame assembly during reciprocating motion, thus improving structural stability.

[0013] Furthermore, the longitudinal section of the bracket is H-shaped.

[0014] By adopting the above technical solution, the shape of the bracket is convenient for arranging slide rails, which facilitates the support of the lateral moving support platform and improves the structural stability.

[0015] Furthermore, a filter press assembly is provided in the middle of one side of the support, and a slurry inlet assembly and a drainage assembly are provided on the other side of the support, and multiple plate and frame assemblies are provided inside the support.

[0016] By adopting the above technical solution, the filter press assembly pushes multiple plate and frame assemblies together, and then the slurry feeding assembly sends the slurry to be dewatered into the multiple plate and frame assemblies to start the filter press operation. The filtered water is discharged through the drainage assembly. After dewatering is completed, the filter press assembly retracts and resets to prepare for the next filter press.

[0017] Furthermore, the pusher assembly is in contact with the plate frame assembly, and the plate frame assembly is slidably connected to the bracket.

[0018] By adopting the above technical solution, the pusher plate assembly is displaced laterally, and the protrusions on the outer surface and back of the plate and frame assembly can be pushed by the pusher plate assembly, which facilitates the separation of multiple plate and frame assemblies. The end of the protrusion near the plate and frame assembly is placed on the top of the support and slidably connected, thereby providing support for the plate and frame assembly. When separating the plate and frame assembly, the plate and frame assembly is displaced towards the filter press assembly, causing the filter cake to fall downwards and be discharged under the influence of gravity.

[0019] Furthermore, a control cabinet is installed on one side of the frame, and the filter press assembly, slurry feed assembly, servo motor and servo cylinder are all electrically connected to the control cabinet.

[0020] By adopting the above technical solution, staff can control the filter press assembly, slurry feeding assembly, servo motor, and servo electric cylinder through the control cabinet.

[0021] Furthermore, the servo motor, ball screw, slide rail, support platform, push plate assembly, servo electric cylinder, slider and slide groove are all provided in two sets, and the two sets of brackets, servo motors, ball screws, slide rails, support platforms, push plate assemblies, servo electric cylinders, sliders and slide grooves are all mirror-distributed along the horizontal axis centerline of the frame.

[0022] By adopting the above technical solution and increasing the number of components, both sides of the plate and frame assembly can be subjected to force simultaneously, thus improving the structural stability.

[0023] In summary, the present invention has the following main advantages:

[0024] 1. This utility model, through the arrangement of a servo electric cylinder, a slider, and a sliding groove, allows the servo electric cylinder to drive the pusher assembly to reciprocate laterally for a period of time after the pusher assembly separates the plate and frame assembly. The inertia generated by this reciprocating lateral motion shakes off the residue adhering to the plate and frame assembly. Compared to rinsing or backwashing with water, this eliminates the need for water, avoiding water pollution and subsequent water treatment. Compared to vibration, the plate and frame assembly only slides laterally between itself and the support, reducing the risk of vibration-induced damage. Compared to sweeping, this does not cause wear on the filter cloth. The structure is simple, the operation is convenient, and cleaning is easy.

[0025] 2. This utility model utilizes a servo motor, ball screw, slide rail, and support platform. The servo motor output drives the ball screw to rotate, while the slide rail reduces friction and provides anti-rotation guidance, allowing the support platform to move laterally. This, in turn, drives the push plate assembly to move laterally, separating it from the frame assembly. Compared to the traditional method of using a belt to drive the push plate assembly, the ball screw combined with the slide rail has a larger load capacity, avoiding the increased belt stress and reduced service life caused by the addition of a servo cylinder and support platform, thus increasing structural stability.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] Example 1:

[0035] A high-efficiency plate and frame filter press dewatering machine, such as Figures 1-4 As shown, the device includes a frame 1, with brackets 2 connected to both sides of the top of the frame 1. The longitudinal section of the brackets 2 is "H"-shaped. A servo motor 8 is installed on one side of the bracket 2, and a ball screw 9 is connected to the output end of the servo motor 8. A slide rail 10 is connected to the top of the bracket 2, and a support platform 11 is connected between the slide rail 10 and the ball screw 9. The support platform 11 is threadedly connected to the ball screw 9 through a ball nut. The support platform 11 is slidably connected to the slide rail 10. A servo cylinder 13 and a slider 14 are respectively installed on the top of the support platform 11. A push plate assembly 12 is installed at the output end of the servo cylinder 13. A slide groove 15 is provided at the bottom of the push plate assembly 12. The push plate assembly 12 is connected to the slider. 14 and 15 are slidably connected to the support platform 11. The longitudinal sections of both slider 14 and 15 are "T" shaped. During the separation of the plate and frame assembly 5, the servo motor 8 stops to prevent the subsequent lateral reciprocating motion of the plate and frame assembly 5 from colliding with other plate and frame assemblies 5. Then, the output end of the servo electric cylinder 13 drives the push plate assembly 12 to reciprocate laterally for a period of time. During this period, slider 14 and 15 guide the push plate assembly 12 to reduce friction. The inertia generated by its reciprocating lateral motion shakes off the residue adhering to the plate and frame assembly 5. After that, the servo motor 8 starts again to cooperate with the push plate assembly 12 to make the plate and frame assembly 5 continue to move towards the filter press assembly 4.

[0036] See Figure 1 and Figure 2In the above embodiment, a filter press assembly 4 is arranged in the middle of one side of the support 2, and a slurry inlet assembly 6 and a drainage assembly 7 are respectively arranged on the other side of the support 2. Multiple plate and frame assemblies 5 are arranged inside the support 2. The pusher assembly 12 contacts the plate and frame assemblies 5, and the plate and frame assemblies 5 are slidably connected to the support 2. A control cabinet 3 is installed on the upper side of one side of the frame 1. The filter press assembly 4, the slurry inlet assembly 6, the servo motor 8, and the servo cylinder 13 are all electrically connected to the control cabinet 3. The operator turns on the filter press assembly 4, the slurry inlet assembly 6, the servo motor 8, and the servo cylinder 13 through the control cabinet 3. The filter press assembly 4 pushes the multiple plate and frame assemblies 5 to fit together. Then, the slurry inlet assembly 6 feeds the slurry to be dewatered into the multiple plate and frame assemblies 5 to start the filter press operation. The filtered water is then filtered through... The drainage component 7 discharges; after dewatering, the filter press component 4 retracts and resets to prepare for the next filter press. The output end of the servo motor 8 drives the ball screw 9 to rotate, and the slide rail 10 reduces friction and provides anti-rotation guidance, causing the support platform 11 to move laterally, thereby driving the push plate component 12 to move laterally. The protrusions on the outer surface and back of the plate frame component 5 can be pushed by the push plate component 12, which facilitates the separation of multiple plate frame components 5. The end of the protrusion near the plate frame component 5 is placed on the top of the bracket 2 and slidably connected, thus providing support for the plate frame component 5. When separating the plate frame component 5, the plate frame component 5 moves towards the filter press component 4, causing the filter cake to fall downwards and be discharged due to gravity. A conveyor or trolley container can be arranged under the frame 1 in advance to receive and transport the fallen filter cake.

[0037] Example 2:

[0038] Based on the above embodiment one, the following settings are now implemented to further enhance stability.

[0039] See Figure 1 and Figure 2 In the above embodiment, the servo motor 8, ball screw 9, slide rail 10, support platform 11, push plate assembly 12, servo electric cylinder 13, slider 14 and slide groove 15 are all provided in two sets. The two sets of brackets 2, servo motor 8, ball screw 9, slide rail 10, support platform 11, push plate assembly 12, servo electric cylinder 13, slider 14 and slide groove 15 are all mirrored along the horizontal axis center line of the frame 1. By increasing the number of sets, both sides of the plate frame assembly can be subjected to force at the same time, so that the structural operation stability is better.

[0040] The implementation principle of this utility model is as follows: First, the filter press assembly 4 pushes multiple plate and frame assemblies 5 together. Then, the slurry feeding assembly 6 feeds the slurry to be dewatered into the multiple plate and frame assemblies 5 to start the filter press operation. The filtered water is discharged through the drainage assembly 7. After dewatering, the filter press assembly 4 retracts and resets to prepare for the next filter press. The output end of the servo motor 8 drives the ball screw 9 to rotate. The slide rail 10 reduces friction and provides anti-rotation guidance, causing the support platform 11 to move laterally, thereby driving the pusher assembly 12 to move laterally. The protrusions on the outer surface and back of the plate and frame assembly 5 can... The plate and frame filter press is pushed by the pusher assembly 12, which facilitates the separation of multiple plate and frame assemblies 5. The end of the protrusion near the plate and frame assembly 5 is slidably connected to the top of the support 2, thereby providing support for the plate and frame assembly 5. When separating the plate and frame assembly 5, the plate and frame assembly 5 moves towards the filter press assembly 4, causing the filter cake to fall downwards and be discharged under the influence of gravity. A conveyor or trolley container can be arranged in advance under the frame 1 to receive and transport the fallen filter cake. The specific working principle of the plate and frame filter press is existing technology and belongs to the public knowledge. This technical solution only briefly describes its structure and principle.

[0041] During the separation of the plate and frame assembly 5, the servo motor 8 stops to prevent the subsequent lateral reciprocating motion of the plate and frame assembly 5 from colliding with other plate and frame assemblies 5. Then, the output end of the servo electric cylinder 13 drives the pusher assembly 12 to reciprocate laterally for a period of time. During this period, the slider 14 and the slide groove 15 guide the pusher assembly 12 to reduce friction. The inertia generated by its reciprocating lateral motion shakes off the residue adhering to the plate and frame assembly 5. After that, the servo motor 8 starts again to cooperate with the pusher assembly 12 to make the plate and frame assembly 5 continue to move towards the filter press assembly 4.
