Technical Field

[0001] This utility model relates to the field of filter press technology, specifically to a filter press for silicon carbide production and processing. Background Technology

[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to a material, causing the liquid to seep out. It is a commonly used solid-liquid separation device that was applied to chemical production in the early 18th century and is still widely used in industries such as chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramics, and environmental protection. The filter plates are stable in performance, easy to operate, safe, and labor-saving. The metal press cylinder is made of seamless steel pipe and precision-cast plastic steel filter plates, which are resistant to high temperature and high pressure and are durable.

[0003] However, in the use of existing filter presses for silicon carbide production and processing, silicon carbide particles may adhere to the filter cloth, causing the filter cloth to become clogged and affecting the filtration effect. Therefore, this utility model provides a filter press for silicon carbide production and processing to improve this problem. Utility Model Content

[0004] The purpose of this utility model is to provide a filter press for silicon carbide production and processing in order to solve the problems in the background art.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A filter press for silicon carbide production and processing includes a frame on which a push rod is slidably mounted via a hydraulic rod. The frame also includes a stop plate.

[0007] The filter plates are slidably mounted on the frame. There are multiple filter plates, and push rods are used to push the filter plates.

[0008] A vibrating element is mounted on a frame. The vibrating element includes a protruding plate that is slidably mounted on a filter plate. A connecting spring is installed between the protruding plate and the filter plate. A protruding structure is provided on the frame. A first inclined surface is provided on the protruding structure. When the protruding plate abuts against the protruding structure, the connecting spring is forced to compress.

[0009] The separator is slidably mounted on the frame and is connected to the filter plates so that when the separator slides, it causes the filter plates to separate from each other.

[0010] Furthermore, an mounting plate is installed on the filter plate, and a column is installed on the adjacent mounting plate, with a hinge rod hinged to the column.

[0011] Furthermore, the separating component includes a connecting plate slidably mounted on the push rod, an extension plate that slides with the frame is mounted on the connecting plate, and a receiving groove is provided on the extension plate for accommodating the free end of the mounting plate.

[0012] Furthermore, the protruding structure includes an abutment plate hinged to the frame, a torsion spring is installed between the abutment plate and the frame, and a limiting plate is installed at the end of the abutment plate near the push rod.

[0013] Furthermore, a guide block is installed on the frame, and a guide groove for accommodating the guide block is provided on the mounting plate.

[0014] Furthermore, a protruding rod is slidably mounted on the guide block, and an abutting spring is installed between the protruding rod and the guide block.

[0015] Furthermore, the limiting plate has an arc-shaped surface on the side facing the contact plate and contacts the contact plate through the arc-shaped surface.

[0016] Furthermore, the mounting plate has an inclined surface on the side where the guide groove is provided, so that the height of the guide groove opening is higher than the height of the protrusion.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. In use, after the silicon carbide is prepared, the filter plate is pulled by the separator to separate it. The filter plate slides on the frame. Since the protruding structure is installed on the frame, when the filter plate slides, the protruding structure and the protruding plate slide relative to each other. When the protruding plate passes the protruding structure, it contacts the protruding structure, causing vibration on the filter plate and forcing the connecting spring to compress. After the filter plate passes the protruding structure, the contact spring resets and pushes the protruding plate to reset, causing vibration on the filter plate again. This allows the silicon carbide to be separated smoothly from the filter plate, increasing the practicality of the device in use. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] like Figures 1-7 As shown in the figure, an embodiment of the present invention discloses a filter press for silicon carbide production and processing, including a frame 1, on which a push rod 101 is slidably mounted via a hydraulic rod. A stop plate 102 is also mounted on the frame 1. A plate is mounted on the telescopic end of the push rod 101. The push rod 101 is mounted on one side of the frame 1, and the stop plate 102 is mounted on the other side of the push rod 101. The free end of the push rod 101 moves towards or away from the stop plate 102. The stop plate 102 is used to limit the maximum extent of the free end of the push rod 101. The device also includes:

[0029] Filter plates 2 are slidably mounted on the frame 1. There are multiple filter plates 2. Push rods 101 are used to push the filter plates 2. There are multiple filter plates 2 slidably mounted on the frame 1. A plate body is installed on the free end of the push rod 101. When the push rod 101 is driven by the hydraulic rod, it pushes the filter plates 2 through the plate body, thereby causing multiple filter plates 2 to slide towards the stop plate 102. When the filter plate 2 furthest from the push rod 101 contacts the stop plate 102, the sliding of the push rod 101 reaches its maximum limit. At this time, multiple filter plates 2 contact each other and perform filtration processing on silicon carbide.

[0030] Vibrating element 3, mounted on frame 1, includes a protruding plate 301 slidably mounted on filter plate 2. A frame plate 12 is mounted on the side wall of filter plate 2. The protruding plate 301 is slidably mounted within the frame plate 12. A plate body is mounted on the side of the protruding plate 301 away from the opening of the frame plate 12. Figure 6As shown, the length of the opening of the frame plate 12 is greater than the length of the protruding plate 301, and the length of the plate body is greater than the length of the frame plate 12, so that when the plate body contacts the inner wall of the frame plate 12, the sliding of the protruding plate 301 within the frame plate 12 reaches the maximum limit.

[0031] A connecting spring 302 is installed between the protruding plate 301 and the filter plate 2. The connecting spring 302 is also installed inside the frame plate 12. The free end of the connecting spring 302 is connected to the protruding plate 301. When the connecting spring 302 is compressed, the protruding plate 301 can slide into the frame plate 12. A protruding structure is provided on the frame 1. A first inclined surface is provided on the protruding structure. When the protruding plate 301 abuts against the protruding structure, the connecting spring 302 is forced to compress. After the device finishes processing silicon carbide, the filter plate 2 needs to be slid to feed the silicon carbide. When the filter plate 2 slides, since the protruding structure is installed on the frame 1, the filter plate 2 drives the protruding plate 301 to slide, causing the protruding structure to slide relative to the protruding plate 301. This allows the protruding structure to abut against the protruding plate 301, and the first inclined surface guides the protruding plate 301 to slide into the frame plate 12.

[0032] Separator 4 is slidably mounted on frame 1. Separator 4 is connected to filter plate 2 so that when separator 4 slides, it drives filter plate 2 to separate from each other. Separator 4 can be a feeding component on an existing filter press so that separator 4 can drive different filter plates 2 to slide for feeding. Separator 4 is used to drive filter plate 2 to slide so that filter plate 2 can be separated, thereby exposing silicon carbide between filter plates 2 for feeding.

[0033] When the device is feeding material, the filter plates 2 are moved away from each other by the separator 4. The protruding plate 301 on the filter plate 2 gradually moves closer to the protruding structure. When the protruding plate 301 and the protruding structure come into contact, the protruding plate 301 and the protruding structure will collide and then come into contact. The collision causes the filter plate 2 to vibrate, making it easier for the silicon carbide remaining on the filter plate 2 to fall off. During the process, the connecting spring 302 is compressed. When the filter plate 2 continues to slide, causing the protruding plate 301 to release from contact with the protruding structure, the connecting spring 302 pushes the protruding plate 301 to reset. During the reset, the protruding plate 301 moves away from the filter plate 2. During the process, the plate body on it comes into contact with the frame plate 12, which causes the filter plate 2 to vibrate again, further facilitating the falling off of the silicon carbide remaining on the filter plate 2.

[0034] When the device is processing silicon carbide, when the filter plates 2 are pushed closer to each other, when they pass through the protrusion mechanism, the protrusion structure abuts against the protrusion plate 301, causing it to slide into the frame plate 12 to make way, so that the filter plates 2 can slide smoothly, increasing the feasibility of the device.

[0035] Compared with the prior art, in use, after the silicon carbide is prepared, when the filter plate 2 is pulled by the separator 4 for separation, the filter plate 2 slides on the frame 1. Since the protruding structure is installed on the frame 1, when the filter plate 2 slides, the protruding structure and the protruding plate 301 slide relative to each other. When the protruding plate 301 passes the protruding structure, it comes into contact with the protruding structure, causing vibration on the filter plate 2 and forcing the connecting spring 302 to compress. After the filter plate 2 passes the protruding structure, the connecting spring 302 resets and pushes the protruding plate 301 to reset, causing vibration on the filter plate 2 again. This allows the silicon carbide to be successfully separated from the filter plate 2, increasing the practicality of the device in use.

[0036] like Figure 2 As shown, in some embodiments, a mounting plate 201 is installed on the filter plate 2, and a column 202 is installed on the adjacent mounting plate 201. A hinge rod 203 is hinged to the column 202. The adjacent mounting plates 201 are connected by the hinge rod 203, so that when one of the filter plates 2 slides, if the sliding distance is greater than the length of the hinge rod 203, the filter plate 2 can be pulled to slide together with the adjacent filter plate 2 through the hinge rod 203. Thus, pulling one filter plate 2 can drive all the filter plates 2 to slide together, which increases the convenience of material feeding.

[0037] like Figure 3 As shown, in some embodiments, the separating member 4 includes a connecting plate 401 slidably mounted on the push rod 101. An extension plate 402, which slidably engages with the frame 1, is mounted on the connecting plate 401. The extension plate 402 has a receiving groove 403 for accommodating the free end of the mounting plate 201. Figure 1 From the main viewpoint, the extension plate 402 is located below the mounting plate 201, and the opening of the receiving groove 403 faces the vertical upward direction. The mounting plate 201 is then received by the receiving groove 403. The filter plate 2 closest to the push rod 101 is set as the head plate, and the receiving groove 403 is connected to the mounting plate 201 located on the head plate.

[0038] When push rod 101 pushes and slides the filter plate 2, the connecting plate 401 slides relative to push rod 101 due to its own weight and friction until the free end of push rod 101 abuts against filter plate 2. At this point, it also drives the connecting plate 401 and extension plate 402 to slide together on the frame 1 along with filter plate 2, so that the receiving groove 403 can always remain connected to the mounting plate 201. After processing is completed, push rod 101 is reset. At this time, the plate at the end of push rod 101 moves away from filter plate 2, causing carbonization between the plate at the end of push rod 101 and filter plate 2. Silicon can also be fed, and during the process, due to the sliding cooperation between the connecting plate 401 and the push rod 101, the position of the connecting plate 401 does not change much due to its own weight and friction. When the plate at the end of the push rod 101 contacts the connecting plate 401, it drives the connecting plate 401 to slide through the contact, and then drives the extension plate 402 to slide through the connecting plate 401, so that the inner wall of the receiving groove 403 can push the filter plate 2 to slide, so that the filter plates 2 can move away from each other and complete the feeding. In use, it is more convenient to feed silicon carbide, which increases the convenience of the device.

[0039] like Figure 4 As shown, in some embodiments, the protruding structure includes an abutment plate 5 hinged to the frame 1, a torsion spring 6 installed between the abutment plate 5 and the frame 1, a limiting plate 7 installed at one end of the abutment plate 5 near the push rod 101, the pivot of the abutment plate 5 being connected to the torsion spring 6, one side of the torsion spring 6 being connected to the frame 1, the elastic coefficient of the torsion spring 6 being less than the elastic coefficient of the connecting spring 302, and when the torsion spring 6 is not affected by external force, the abutment plate 5 is in an inclined state to form a first inclined surface, the inclination angle of which is as follows: Figure 4 As shown, when the filter plates 2 approach each other, the protruding plate 301 abuts against the contact plate 5. Since the elastic coefficient of the torsion spring 6 is less than that of the connecting spring 302, the connecting spring 302 will not deform at this time. Instead, the contact plate 5 will rotate until it makes way for the protruding plate 301. When the filter plates 2 move away from each other, the protruding plate 301 abuts against the contact plate 5 again. At this time, the rotation direction of the contact plate 5 is restricted by the blocking of the limiting plate 7. At this time, the protruding plate 301 is rigidly abutted and retracted, causing vibration on the filter plate 2. Through the above arrangement, the connecting spring 302 is only compressed when feeding, which reduces the possibility of fatigue caused by repeated deformation of the connecting spring 302 during use and increases the service life of the connecting spring 302.

[0040] like Figure 1 and Figure 2As shown, in some embodiments, a guide block 8 is installed on the frame 1, and a guide groove 9 for accommodating the guide block 8 is provided on the mounting plate 201. The inner wall of the guide groove 9 contacts the side wall of the guide block 8, so that when the mounting plate 201 slides, the inner wall of the guide groove 9 is restricted by the side wall of the guide block 8, so that the mounting plate 201 can only slide on the frame 1 in a straight line, which increases the stability of the sliding of the mounting plate 201 and the filter plate 2 on the frame 1.

[0041] In some embodiments, a protruding rod 10 is slidably mounted on the guide block 8, and an abutment spring 11 is installed between the protruding rod 10 and the guide block 8. The guide block 8 has a channel, and both the protruding rod 10 and the abutment spring 11 are installed in the channel. When the protruding rod 10 is subjected to an external force, it can slide into the channel. The free end of the protruding rod 10 has rounded corners. When the abutment spring 11 is at its original length, the height of the protruding rod 10 is higher than the highest point of the guide groove 9. When the filter plate 2 slides to the point where the end of the protruding rod 10 contacts the guide groove 9, the two collide first, causing the filter plate 2 to vibrate again, which increases the feeding effect on the filter plate 2. After the two come into contact, the push rod 101 continues to pull the filter plate 2 to move, so that the inner wall of the guide groove 9 continues to abut against the protruding rod 10. Through the guidance of its rounded corners, the mounting plate 201 can press the protruding rod 10 downward, causing the protruding rod 10 to give way to the mounting plate 201, so that the filter plate 2 can slide smoothly, which increases the practicality of the device.

[0042] like Figure 4 As shown, in some embodiments, the limiting plate 7 has an arc-shaped surface on the side facing the contact plate 5 and contacts the contact plate 5 through the arc-shaped surface. Compared with contacting the contact plate 5 through a sharp corner, the contact between the limiting plate 7 and the contact plate 5 through the arc-shaped surface can greatly reduce the wear between the limiting plate 7 and the contact plate 5 and increase the practicality of the device.

[0043] like Figure 2 As shown, in some embodiments, the mounting plate 201 has a slope on the side where the guide groove 9 is provided, so that the height of the opening of the guide groove 9 is higher than the height of the protruding rod 10. The slope only expands the height of the opening of the guide groove 9 so that the height of the opening of the guide groove 9 can be higher than the height of the protruding rod 10, but the maximum height inside the guide groove 9 is still lower than the height of the protruding rod 10 in normal condition. When the guide groove 9 and the protruding rod 10 are in contact, the guide of the rounded corner at the end of the protruding rod 10 and the slope at the opening of the guide groove 9 allows the inner wall of the guide groove 9 to have more space to press the protruding rod 10, which increases the feasibility of the device.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
