Description

Technical Field

[0001] This utility model relates to the field of plate and frame filter press technology, and in particular to a plate and frame filter press device for lithium perchlorate solution. Background Technology

[0002] Plate and frame filter press is an intermittent pressure filtration device, primarily used for solid-liquid separation of suspensions. Its structure is based on the alternating arrangement of filter plates and frames, combined with a pressing mechanism, filter cloth, and inlet and outlet pipelines. The pressing mechanism seals the plates and frames to form independent filtration chambers. During operation, external pressure creates a pressure difference, allowing the liquid in the suspension to pass through the filter cloth. The filtrate is discharged along the guide grooves of the filter plates, while solid particles accumulate in the plates and frames to form a filter cake, completing the cycle of "pressing - filtering - cake discharge - resetting".

[0003] The patent application number "202221604003.2" entitled "A Highly Automated Plate and Frame Filter Press for Solid-Liquid Separation" describes a device that uses anti-wear pads to reduce friction between the L-shaped movable plate and the plate and frame limiting plate and the connecting plate when the device is pushed backward or pulled forward by a linear motor and cable drag chain. This prevents severe wear between the connecting plate, the L-shaped movable plate and the plate and frame limiting plate, which could lead to the risk of the plate and frame shifting or even collapsing inside the device.

[0004] However, the device has the following problems when in use: after filtration, it cannot automatically separate the filter plate and the plate frame, and manual separation is still required, which reduces the efficiency of filter cake disassembly. In this application, a separation spring is set between the filter plate and the plate frame. The spring force of the separation spring can realize the automatic separation of the filter plate and the plate frame, and the cost is lower than that of the existing automatic separation structure. Utility Model Content

[0005] The purpose of this invention is to provide a plate and frame filter press for lithium perchlorate solution, which solves the problem that existing plate and frame filter presses cannot automatically separate the filter plates and frames after filtration, still requiring manual separation and reducing the efficiency of filter cake removal.

[0006] To achieve the above objectives, a plate and frame filter press for lithium perchlorate solution is provided, comprising: a base, a filter press body fixedly connected to the top of the base, a cylinder fixedly mounted on one side of the filter press body, a pressing plate fixedly connected to the output end of the cylinder, an mounting plate fixedly connected to the top of the filter press body, a connecting rod fixedly connected to the inner side of the mounting plate, filter plates and plate frames alternately arranged on the outer wall of the connecting rod, and a separation spring provided between the filter plates and plate frames, the separation spring being sleeved on the connecting rod to facilitate the automatic separation of the filter plates and plate frames, thereby facilitating the removal of the filter cake; Both sides of the filter plate and the plate frame are fixedly connected to an arc-shaped plate. Both sides of the filter plate and the plate frame are provided with sliding grooves. The inner wall of the sliding groove is fixedly connected to a sliding rod. The outer wall of the sliding rod is slidably connected to an arc-shaped plate. Both sides of the arc-shaped plate are provided with movable holes. The interior of the movable holes is fixedly connected to a positioning spring. One end of the positioning spring is fixedly connected to a positioning screw. The outer wall of the positioning screw is fixedly connected to a lever, which facilitates the installation or disassembly of the filter plate and the plate frame, thereby facilitating their cleaning or replacement.

[0007] According to the plate and frame filter press device for lithium perchlorate solution, a collection trough is provided on one side of the base, and a collection frame is movably connected inside the collection trough to facilitate the collection of filter cake.

[0008] According to the plate and frame filter press device for lithium perchlorate solution, the top of the second arc plate is provided with a through hole, and the second arc plate is slidably connected to the outer wall of the slide rod through the through hole, which facilitates the up and down movement of the arc plate.

[0009] According to the plate and frame filter press equipment for lithium perchlorate solution, the shape, size and position of the first arc plate and the second arc plate are all corresponding to each other, which facilitates the installation or disassembly of the filter plate and the plate frame.

[0010] According to the plate and frame filter press for lithium perchlorate solution, the diameter of the movable hole is larger than the diameter of the positioning screw, and the positioning screw is slidably connected to the inner wall of the movable hole.

[0011] According to the plate and frame filter press device for lithium perchlorate solution, a positioning hole is provided on one side of the first arc plate. The shape and size of the positioning hole are matched with the shape and size of the positioning screw. The positioning screw is movably connected to the positioning hole under the action of the positioning spring, which facilitates the connection between the first arc plate and the second arc plate.

[0012] According to the plate and frame filter press device for lithium perchlorate solution, a groove is provided on one side of the arc plate, the groove is connected to the movable hole, and the lever is slidably connected to the inner wall of the groove to facilitate the retraction of the positioning screw.

[0013] According to the plate and frame filter press equipment for lithium perchlorate solution, the outer wall of the positioning screw is provided with threads, and the positioning screw cooperates with the limiting nut through the threads to prevent the positioning screw from retracting.

[0014] The above-mentioned solution has the following beneficial effects: 1. This plate and frame filter press equipment has a connecting rod at the top of the filter press body, with filter plates and frames alternately arranged on the connecting rod. Separation springs are installed between the filter plates and frames. During the filtration process, the cylinder drives the pressing plate to press the filter plates and frames together to form a sealed chamber, and also drives the separation springs between the filter plates and frames to compress. After filtration is completed, the cylinder drives the pressing plate to retract, and the filter plates and frames automatically separate under the elastic force of the separation springs. This improves the separation rate of the filter plates and frames and increases the efficiency of filter cake disassembly.

A sliding rod is installed within the groove, and an arc-shaped plate is slidably connected to the outer wall of the sliding rod. The filter plate and plate frame can be mounted on the sliding rod through the connection between the arc-shaped plate and the arc-shaped plate. Movable holes are provided on both sides of the arc-shaped plate, with a positioning spring and a positioning screw installed within each hole. The spring force of the positioning spring allows the positioning screw to engage with the positioning hole on the arc-shaped plate, facilitating the installation of the filter plate and plate frame. For disassembly, moving the lever inwards on the arc-shaped plate causes the positioning screw to retract into the movable hole, disconnecting the positioning screw from the positioning hole. Moving the arc-shaped plate upwards releases the connection between the arc-shaped plate and the arc-shaped plate, facilitating the disassembly of the filter plate or plate frame for subsequent replacement or cleaning.

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] Reference Figure 1-3 This utility model discloses a plate and frame filter press for lithium perchlorate solution, comprising: a base 1, a filter press body 3 fixedly connected to the top of the base 1, a cylinder 4 fixedly mounted on one side of the filter press body 3, a pressing plate 5 fixedly connected to the output end of the cylinder 4, an mounting plate 6 fixedly connected to the top of the filter press body 3, a connecting rod 7 fixedly connected to the inner side of the mounting plate 6, filter plates 9 and plate frames 8 alternately arranged on the outer wall of the connecting rod 7, and a separation spring 21 is provided between the filter plates 9 and the plate frames 8, and the separation spring 21 is sleeved on the connecting rod 7. The elastic force of the separation spring 21 can drive the filter plates 9 and the plate frames 8 to automatically separate, thereby facilitating the disassembly of the filter cake.

[0021] A collection trough is provided on one side of the base 1, and a collection frame 2 is movably connected inside the collection trough to facilitate the collection of filter cake.

[0022] Reference Figure 3-6 Both sides of the filter plate 9 and the plate frame 8 are fixedly connected to an arc-shaped plate 10. Both sides of the filter plate 9 and the plate frame 8 are provided with sliding grooves. The inner wall of the sliding groove is fixedly connected to a sliding rod 12. The outer wall of the sliding rod 12 is slidably connected to an arc-shaped plate 13. Both sides of the arc-shaped plate 13 are provided with movable holes 15. The movable holes 15 are fixedly connected to a positioning spring 16. One end of the positioning spring 16 is fixedly connected to a positioning screw 17. The outer wall of the positioning screw 17 is fixedly connected to a lever 18. The elastic force of the positioning spring 16 can drive the positioning screw 17 to be inserted into the positioning hole 11, thereby facilitating the connection between the arc-shaped plate 10 and the arc-shaped plate 13, and thus facilitating the installation of the filter plate 9 and the plate frame 8. When disassembling, the lever 18 is pushed inward to the arc-shaped plate 13, which can drive the positioning screw 17 to retract, thereby disconnecting the connection between the positioning screw 17 and the positioning hole 11, thus facilitating the disassembly of the filter plate 9 or the plate frame 8.

[0023] The top of the arc-shaped plate 13 has a through hole 14. The arc-shaped plate 13 is slidably connected to the outer wall of the slide rod 12 through the through hole 14. The arc-shaped plate 13 can move up and down through the slide rod 12, which facilitates the installation or disassembly of the filter plate 9 and the plate frame 8.

[0024] The shapes, sizes, and positions of the arc-shaped plate 10 and the arc-shaped plate 2 13 correspond to each other.

[0025] The diameter of the movable hole 15 is larger than the diameter of the positioning screw 17, and the positioning screw 17 is slidably connected to the inner wall of the movable hole 15.

[0026] A positioning hole 11 is provided on one side of the arc plate 10. The shape and size of the positioning hole 11 match the shape and size of the positioning screw 17. The positioning screw 17 is movably connected to the positioning hole 11 under the action of the positioning spring 16, which facilitates the connection between the arc plate 10 and the arc plate 13, thereby facilitating the installation of the filter plate 9 and the plate frame 8.

[0027] A groove 19 is provided on one side of the arc plate 13. The groove 19 is connected to the movable hole 15. The lever 18 is slidably connected to the inner wall of the groove 19. By moving the two levers 18 towards the inner side of the arc plate 13, the positioning screw 17 can be driven to retract into the movable hole 15 and compress the positioning spring 16, thereby facilitating the subsequent installation or disassembly of the filter plate 9 and the plate frame 8.

[0028] The outer wall of the positioning screw 17 is provided with threads. The positioning screw 17 is engaged with the limiting nut 20 through the threads. The limiting nut 20 can prevent the positioning screw 17 from retracting, thereby improving the stability of the connection between the arc plate 10 and the arc plate 2 13.

[0029] Working principle: Before filtration, filter plate 9 and plate frame 8 are alternately installed on connecting rod 7, with separation spring 21 positioned between filter plate 9 and plate frame 8. Two levers 18 are moved inwards towards the inner side of arc-shaped plate 13, causing positioning screw 17 to retract into movable hole 15 and compress positioning spring 16. Simultaneously, arc-shaped plate 13 is moved downwards, aligning the position of positioning screw 17 with the position of positioning hole 11 on arc-shaped plate 10. The levers 18 are released, and positioning screw 17, under the elastic force of positioning spring 16, engages with positioning hole 11. By inserting the plug and using the limiting nut 20 to limit the protruding part of the positioning screw 17, the connection between the arc plate 10 and the arc plate 13 can be completed, thereby completing the installation of the filter plate 9 or the plate frame 8. The cylinder 4 drives the pressing plate 5 to press the filter plate 9 and the plate frame 8 to form a sealed chamber. The lithium perchlorate solution is introduced from the feed port to start filtration. After filtration is completed, the cylinder 4 drives the pressing plate 5 to retract, and the filter plate 9 and the plate frame 8 automatically separate under the elastic force of the separation spring 21, which facilitates the disassembly of the filter cake. When it is necessary to disassemble the filter plate 9 or the plate frame 8, remove the limiting nuts 20 on both sides, and move the two levers 18 inward to the inside of the arc plate 2 13. This will cause the positioning screw 17 to retract into the movable hole 15 until it disconnects from the positioning hole 11. Move the arc plate 2 13 upward to disconnect the connection between the arc plate 2 13 and the arc plate 1 10, so that the filter plate 9 or the plate frame 8 can be removed for cleaning.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
