Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to a simple device for cleaning filter cloth of a filter press. Background Art

[0002] The filter cloth is a key component of the filter press for solid-liquid separation. The function of the filter cloth is to allow liquid to pass through under pressure while intercepting solid particles to form the so-called filter cake. The performance of the filter cloth directly affects the filtration efficiency of the filter press and the quality of the filter cake.

[0003] In order to restore the filtering performance of the filter cloth and remove the solid residues accumulated on it, it is often necessary to clean the filter cloth of the filter press. One of the equipment currently used is a horizontal filter cloth cleaning machine.

[0004] However, in actual use, the current horizontal filter cloth cleaning machine has a cover plate on its surface, covering the entire cleaning roller underneath, and a mesh cover is also provided on the surface of the cleaning roller. When taking the filter, it is necessary to first slide open the outer cover plate, and then flip up the mesh cover. However, because the mesh cover is hinged, after it is flipped up, it is necessary to limit it by inserting a rod horizontally on the side of the cleaning machine to prevent it from flipping down by itself. However, this results in that when opening the mesh cover, one hand is required to flip up the mesh cover, and the other hand is required to open the insertion rod. The overall operation is very inconvenient. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1-Figure 6 A simple device for cleaning filter cloth of a filter press comprises a cleaning machine body 1, a cover plate 2 installed on the cleaning machine body 1 and a mesh cover 6 installed on the roller inside the cleaning machine body 1. The upper surface of the outer wall of the cleaning machine body 1 is fixedly connected with two symmetrically arranged L-shaped rods 3, and the two L-shaped rods 3 are connected to a limiting component on one side close to the cover plate 2. The two L-shaped rods 3 are respectively located on both sides of the cover plate 2 and the mesh cover 6. Both ends of the mesh cover 6 are fixedly connected with connecting rods 7, and the other ends of the two connecting rods 7 are fixedly connected with fixing blocks 8. The other ends of the two fixing blocks 8 are connected with elastic components, and the two elastic components are respectively connected to the two limiting components.

[0023] The simple device for cleaning filter cloth of the filter press in the utility model is similar in structure to the existing filter cloth cleaning machine, such as the filter cloth cleaning machine of model: XGP-50. Figures 1 to 6As shown, before and after the user cleans the filter cloth of the filter press through the cleaning machine body 1, he first slides the outermost cover plate 2 toward the rear of the cleaning machine body 1 to open it, and then loosens the limit between the mesh cover 6 and the roller of the cleaning machine body 1, and then rotates the mesh cover 6 upward to open it. When the mesh cover 6 is flipped upward to open, the two connecting rods 7, two fixing blocks 8 and two elastic components at both ends of the mesh cover 6 will flip together, and when the two elastic components of the two fixing blocks 8 are rotated to a certain angle, they will contact the limit components on the L-shaped rod 3 fixed on the cleaning machine body 1, and after the elastic components and the limit components are in contact with each other, the elastic components and the limit components are limited to each other, and the limit between the mesh cover 6 and the cleaning machine body 1 can be completed. When the mesh cover 6 needs to be closed, it only needs to be pressed again to complete the separation. The operation is simple and can be operated with one hand.

[0024] Please refer to Figure 1-Figure 6 The inner walls of the two fixed blocks 8 are provided with an active cavity 801, two sockets 802 and two spring cavities 803. The two sockets 802 and the two spring cavities 803 are respectively located on both sides of the active cavity 801, and the two spring cavities 803 are respectively connected with the active cavity 801 through the two sockets 802. The two elastic components are respectively located in the two sockets 802 and the two spring cavities 803, and the limit component is located in the active cavity 801.

[0025] More specifically, by providing the movable cavity 801, two sockets 802 and two spring cavities 803, not only can the elastic component and the limit component be stored therein, but the external space occupied by the two can also be reduced, and it will also be relatively more beautiful.

[0026] Please refer to Figure 1-Figure 6 The limiting assembly includes a movable block 4, a fixed ball 5 and a support rod 10, one end of the support rod 10 is fixedly connected to the end of the L-shaped rod 3 away from the cleaning machine body 1, and the other end of the support rod 10 is fixedly connected to one side of the fixed ball 5. The movable block 4 is sleeved and slidably connected to the outer wall of the support rod 10, and the outer walls of the fixed ball 5 and the movable block 4 are both slidably connected to the inner wall of the movable cavity 801, and the fixed ball 5 and the movable block 4 are connected to both elastic components.

[0027] More specifically, under normal circumstances, because the support rod 10 is in an inclined state, the movable block 4 will slide in the direction of the support rod 10 approaching the L-shaped rod 3 due to its own gravity.

[0028] When the elastic component inside the fixed block 8 rotates with the mesh cover 6 to contact the fixed ball 5, the elastic component will be squeezed along the curved surface of the fixed ball 5 and stop after completely passing through the fixed ball 5. At this time, the elastic component will be against the straight surface on the back of the fixed ball 5 and cannot be turned back to the roller due to gravity or other reasons.

[0029] When it is necessary to close the net cover 6, just push the net cover 6 toward the direction of the L-shaped rod 3 again. At this time, the elastic component will contact the movable block 4 located at the rear end of the L-shaped rod 3, and because both ends of the movable block 4 are inclined surfaces, the elastic component will also move along the surface of the movable block 4 to the other side of the movable block 4, and then the net cover 6 will be rotated to its original position. At this time, due to the extrusion force of the elastic component itself, the movable block 4 will be clamped and moved toward the direction of the fixed ball 5 until it is blocked by the fixed ball 5 and cannot move and stops. At this time, because the net cover 6 continues to move, and because the other side of the movable block 4 is also an inclined surface, the elastic component will continue to be squeezed, and at the moment it is squeezed back into the spring cavity 803, it will detach from the surface of the fixed ball 5, thereby separating the net cover 6. The overall operation is very simple, and only requires pushing forward and then pulling back.

[0030] Please refer to Figure 1-Figure 6 The elastic component includes a push plate 11, a trapezoidal block 12 and a slide bar 9. The outer wall of the trapezoidal block 12 is slidably connected to the inner wall of the socket 802. One end of the trapezoidal block 12 located in the movable cavity 801 is connected to the fixed ball 5 and the movable block 4. One end of the trapezoidal block 12 located in the spring cavity 803 is fixedly connected to the push plate 11. The other side of the push plate 11 is fixedly connected to one end of the slide bar 9. The other end of the slide bar 9 passes through the spring cavity 803. The outer wall of the push plate 11 is slidably connected to the inner wall of the spring cavity 803. The side of the push plate 11 away from the trapezoidal block 12 is fixedly connected with an extrusion spring 13. The other end of the extrusion spring 13 is fixedly connected to the inner wall of the spring cavity 803. The extrusion spring 13 is sleeved on the outer wall of the slide bar 9. A receiving port 501 is provided on the side of the fixed ball 5 close to the movable block 4. The outer wall of the movable block 4 is slidably connected to the inner wall of the receiving port 501, and the sizes match.

[0031] More specifically, at the moment when the trapezoidal block 12 contacts the curved surface of the fixed ball 5, the trapezoidal block 12 will move the push plate 11 and the slide rod 9 toward the spring cavity 803, and compress the extrusion spring 13 at the moment of movement. When the trapezoidal block 12 completely passes through the fixed ball 5, the extrusion spring 13 instantly recovers its deformation, and then the back of the trapezoidal block 12 abuts against the straight surface of the fixed ball 5. Therefore, due to the obstruction of the fixed ball 5, the trapezoidal block 12 cannot be detached.

[0032] When the net cover 6 needs to be turned down, it is only necessary to push the net cover 6 in the direction of the L-shaped rod 3. At this time, the trapezoidal block 12 contacts the inclined surface of the movable block 4. At this time, the squeezing spring 13 is compressed, and the trapezoidal block 12 stops after passing through the highest point of the movable block 4. At this time, the squeezing spring 13 will clamp the other side of the movable block 4, and then pull the net cover 6 backward. At this time, the movable block 4 will move toward the direction of the fixed ball 5 together with the squeezing spring 13. When the movable block 4 is against the receiving opening 501 on the back of the fixed ball 5, the highest point in the middle of the movable block 4 is flush with the surface of the fixed ball 5. At this time, the squeezing spring 13 will move along the surface of the movable block 4, and then it can be detached from the surface of the fixed ball 5. It is simple and easy to operate.

[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
