Description

Technical Field

[0001] This utility model relates to the field of filter press technology, specifically to a filter press unloading device with micro-vibration function. Background Technology

[0002] In the solid-liquid separation industry, separating a mixture of solid and liquid materials into solid and liquid components is a crucial and essential step. Solid-liquid separation technology is widely used in numerous fields such as chemical engineering, environmental protection, pharmaceuticals, food processing, and mining. Its purpose is to recover valuable solid materials, remove suspended solids from wastewater, purify water quality, or meet other specific process requirements.

[0003] The working principle of a filter press is to achieve solid-liquid separation by applying a pressure difference. The filter chamber consists of alternating filter plates (with filter cloth grooves) and filter frames. The filter plates are pressed together by a hydraulic system to form a sealed space. Filter cloth covers the grooves of the filter plates to trap solid particles. Liquid is pressurized by a feed pump and enters the filter chamber, forming filtrate on the filter cloth before being discharged. Solid particles are trapped in the filter chamber and gradually form a filter cake. Traditional filter presses produce a filter cake after filtration. During the filtration process, due to the direct contact between the filter cake and the filter cloth, adhesion can form between the filter cake and the filter cloth or filter plate, making unloading difficult.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model discloses a filter press unloading device with micro-vibration function, including a first support 1, a support frame 2 at the top of the first support 1, multiple alternately arranged filter plates 3 on the support frame 2, and suspension plates 301 on both sides of the filter plates 3 suspended from the side plates of the support frame 2. A hydraulic system (the core actuator of the hydraulic system is a main clamping cylinder) is provided at one end of the support frame 2 to press the filter plates 3. A feed pump is installed at the feed end of the first support 1 and the support frame 2. Micro-vibration mechanisms 4 for driving the filter plates 3 to vibrate up and down are provided on both outer walls of the support frame 2. The micro-vibration mechanism 4 includes a liftable mounting plate 5 on the outer wall of the support frame 2. A movable plate 7 is connected to the outer wall of the mounting plate 5 via a guide sliding assembly 6. Multiple equidistant triangular wedge blocks 8 are provided at the top of the movable plate 7. A spring damping seat 9 (the spring damping seat 9 is prior art and known to those skilled in the art) is located on the left side of each triangular wedge block 8 at the top of the movable plate 7. The movable plate 7 is equipped with a mechanism for driving the filter plates 3 to vibrate up and down. The drive assembly 10 drives the moving plate 7 to move horizontally. The bottom end of the suspension plate 301 is provided with a fixed wedge block 16 that engages with the inclined surface of the triangular wedge block 8. The drive assembly 10 drives the moving plate 7 to move horizontally. After the triangular wedge block 8 on the moving plate 7 engages with the fixed wedge block 16 on the suspension plate 301, as the moving plate 7 continues to move, the suspension plate 301 moves upward, thereby causing the filter plate 3 to move upward. When the triangular wedge block 8 separates from the fixed wedge block 16, the filter plate 3 moves downward under its own gravity. When the filter cake falls, the spring damping seat 9 can buffer and dampen the suspension plate 301, generating micro-vibrations. Whenever a triangular wedge block 8 separates from the fixed wedge block 16 (the inclination angle between the triangular wedge block 8 and the fixed wedge block 16 is ), a micro-vibration is generated. The micro-vibration acts on the filter cake, reducing the adhesion between the filter cake and the filter cloth, thus making it easier to unload the filter cake. This allows the filter cake to be unloaded smoothly under the action of minimal external force, reducing material residue and equipment wear during the unloading process and improving unloading efficiency.

[0026] Specifically, such as Figure 5 and Figure 6As shown, the outer wall of the support frame 2 is provided with a lifting adjustment assembly 11 for driving the mounting plate 5 to rise and fall. The lifting adjustment assembly 11 includes a hydraulic cylinder 1101 installed on the outer wall of the support frame 2. The output shaft of the hydraulic cylinder 1101 is provided with a connecting block 1102 connected to the bottom middle side of the mounting plate 5. The output shaft of the hydraulic cylinder 1101 drives the mounting plate 5 to rise and fall through the connecting block 1102. A PLC controller is installed on the filter press to control the operation of the hydraulic cylinder 1101, thereby adjusting the height of the mounting plate 5. According to the adjusted height of the mounting plate 5, the amplitude of micro-vibration can be adjusted. Alternatively, after the moving plate 7 moves from the left to the right, the output shaft of the hydraulic cylinder 1101 pushes the mounting plate 5 to the bottom, and the drive assembly 10 drives the moving plate 7 back to the left (when the moving plate 7 returns after the mounting plate 5 moves to the bottom, the triangular wedge block 8 and the fixed wedge block 16 will not come into contact).

[0027] The lifting adjustment assembly 11 also includes a first guide slide rail 1103 mounted on the support frame 2, and a first guide slider 1104 that cooperates with the first guide slide rail 1103 on the inner wall of the mounting plate 5. The first guide slider 1104 moves inside the first guide slide rail 1103, which improves the stability of the mounting plate 5 moving up and down.

[0028] Specifically, such as Figure 3 As shown, the guide sliding assembly 6 includes a second guide slide rail 601 located at the top of the mounting plate 5, and a second guide slider 602 that cooperates with the second guide slide rail 601 is provided on the back of the moving plate 7. The second guide slider 602 moves inside the second guide slide rail 601, which improves the stability of the horizontal movement of the moving plate 7.

[0029] Specifically, such as Figure 3 As shown, the drive assembly 10 includes a rack 1001 located at the bottom of the movable plate 7. A gear 1002 meshes with the rack 1001 on the mounting plate 5. An L-shaped mounting support plate 1003 is provided on the outer wall of the mounting plate 5. A servo motor 1004 that drives the gear 1002 to rotate is mounted on the mounting support plate 1003. The output shaft of the servo motor 1004 drives the gear 1002 to rotate. The gear 1002 meshes with the rack 1001, causing the rack 1001 to drive the movable plate 7 to move horizontally. The length of the rack 1001 is set according to the actual use to ensure that after the gear 1002 meshes with the rack 1001, the triangular wedge block 8 lifts all the filter plates 3.

[0030] The filter press unloading device also includes a second support 12 located inside the first support 1. The top of the second support 12 is provided with an installation frame 13, and the inside of the installation frame 13 is provided with a conveyor belt 14. The material after micro-vibration unloading falls onto the conveyor belt 14, which facilitates the unloading of the material and makes unloading easier.

[0031] The mounting frame 13 is provided with guide baffles 15 located on both sides of the conveyor belt 14. The guide baffles 15 are inclined outwards, and the inclination angle of the guide baffles 15 is in the range of 30°-45°. They can limit and protect the materials, and prevent the materials from falling from both sides of the conveyor belt 14.

[0032] During unloading, the output shaft of the servo motor 1004 drives the gear 1002 to rotate. The gear 1002 meshes with the rack 1001, causing the rack 1001 to drive the moving plate 7 to move horizontally. The drive assembly 10 drives the moving plate 7 to move horizontally. After the triangular wedge block 8 on the moving plate 7 engages with the fixed wedge block 16 on the suspension plate 301, the suspension plate 301 moves upward as the moving plate 7 continues to move, thereby causing the filter plate 3 to move upward. When the triangular wedge block 8 separates from the fixed wedge block 16, the filter plate 3 falls downward under its own weight. The spring damping seat 9 can buffer and dampen the suspension plate 301, generating micro-vibrations, causing multiple filter plates 3 to vibrate up and down in sequence. The micro-vibrations act on the filter cake, causing the filter cake and filter cloth to... The adhesion between them is reduced, making unloading easier; when the moving plate 7 moves from one end to the other, the lifting adjustment component 11 causes the mounting plate 5 to move downward (until the moving plate 7 moves horizontally and does not collide with the fixed wedge block 16), the output shaft of the servo motor 1004 drives the gear 1002 to rotate in the opposite direction, the gear 1002 meshes with the rack 1001, causing the rack 1001 to drive the moving plate 7 to move horizontally in the opposite direction, so that the moving plate 7 moves to the initial position, the lifting adjustment component 11 causes the mounting plate 5 to move upward, so that when the moving plate 7 moves horizontally, the triangular wedge block 8 engages with the fixed wedge block 16 on the suspension plate 301, and as the moving plate 7 continues to move, the suspension plate 301 can move upward.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
