Description

Technical Field

[0001] This utility model relates to the field of filters, and in particular to a silicon carbide-based foam ceramic filter for casting. Background Technology

[0002] For example, patent application number 202221229364.3 discloses a silicon carbide-based foam ceramic filter for casting, specifically relating to the field of ceramic filter technology. It includes a housing with a frame plate inside, and a filter screen inside the frame plate. One end of the frame plate penetrates the housing and extends to the outer wall surface of the housing. An outlet is opened at the top of the housing, and a hopper is located above the outlet. The application uses a motor to drive a pulley to rotate, causing the material inside the hopper to evenly fall onto the filter screen for filtration, preventing material accumulation and affecting the filtration speed. Simultaneously, a brush at the bottom of the conveying pipe scrapes the surface of the filter screen back and forth, further dispersing the material and improving the filtration speed. The structure is simple, requires no manual operation, and is very convenient to use.

[0003] Since the filter screen in the above application is directly fixed inside the box, after the filter screen filters a certain amount of material, a certain amount of impurities will accumulate on the filter screen, thereby affecting the filtration efficiency of the filter screen. Furthermore, the directly fixed filter screen is not easy to disassemble and clean, thus having certain defects. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] This utility model provides, for example Figure 1-3 The image shows a silicon carbide-based foam ceramic filter for casting.

[0037] Example 1: Includes a housing 1, a hopper 2, a filter screen 3, a connecting rail 4, a sealing plate 5, and a locking assembly 6. The hopper 2 is movably mounted on the top of the housing 1. A screw mechanism is installed on the housing 1 to drive the hopper 2 to reciprocate. That is, two screws are synchronously rotated by a motor, thereby driving the hopper 2 to reciprocate. This is prior art and will not be described in detail here. The front of the housing 1 has an opening that matches the filter screen 3, so that the filter screen 3 can be pulled out of the housing 1 through the opening to clean the impurities in the filter screen 3. The connecting rail 4 is fixedly connected to the inside of the housing 1. The side of the filter screen 3 is slidably fitted with the connecting rail 4 to ensure the stability of the filter screen 3 installed inside the housing 1. The sealing plate 5 is fixedly connected to the front of the filter screen 3, and the back of the sealing plate 5 is in contact with the housing 1. The locking assembly 6 is set on the front of the housing 1. The locking assembly 6 is used to lock the sealing plate 5. The locking assembly 6 cooperates with the sealing plate 5 to ensure the stability of the filter screen 3 installation.

[0038] Furthermore, the locking assembly 6 includes a mounting plate 61, a positioning plate 62, a locking rod 63, and a handle 64. The mounting plate 61 is mounted on the front of the sealing plate 5, and the positioning plate 62 is fixedly connected to the front of the housing 1. A connecting hole is provided at the bottom of the front of the mounting plate 61. The outer wall of the positioning plate 62 is slidably sleeved with the inner cavity of the connecting hole. The outer wall of the locking rod 63 is slidably inserted into the mounting plate 61. A positioning groove is provided at the top of the positioning plate 62. The bottom of the outer wall of the locking rod 63 is slidably engaged with the inner cavity of the positioning groove. The engagement of the locking rod 63 with the positioning plate 62 can keep the mounting plate 61 and the positioning plate 62 in a stable state, thereby ensuring the stability of the installation of the sealing plate 5. The handle 64 is located at the top of the mounting plate 61, and the top of the locking rod 63 is fixedly connected to the handle 64. Pulling the handle 64 upward can cause the handle 64 to drive the two locking rods 63 to move upward, separating the locking rods 63 from the positioning plate 62, thereby unlocking the sealing plate 5 and disassembling the filter screen 3.

[0039] Furthermore, the locking assembly 6 also includes a bearing groove 65, a first connecting plate 66, and a limiting spring 67. The bearing groove 65 is formed on the back of the mounting plate 61. The first connecting plate 66 is fixedly connected to the outside of the locking rod 63 and is slidably disposed inside the bearing groove 65. The limiting spring 67 is disposed on the top of the first connecting plate 66. The limiting spring 67 can exert an elastic compressive force on the locking rod 63 through the first connecting plate 66, thereby keeping the locking rod 63 and the positioning plate 62 in a stable latching state.

[0040] Example 2: Based on Example 1, the locking assembly 6 further includes a fixing plate 69, a second connecting plate 610, and a positioning rod 611. The fixing plate 69 is fixedly connected to the front of the sealing plate 5. The back of the mounting plate 61 has a groove that matches the fixing plate 69. The second connecting plate 610 is slidably sleeved on the outside of the locking rod 63. The second connecting plate 610 is located at the top of the limiting spring 67. One end of the positioning rod 611 is fixedly connected to the second connecting plate 610. The outer wall of the positioning rod 611 is slidably sleeved with the mounting plate 61. The bottom of the fixing plate 69 has a positioning groove that matches the positioning rod 611. Under the action of the limiting spring 67, the second connecting plate 610 can drive the positioning rod 611 to maintain a stable locking state with the positioning groove on the fixing plate 69, thereby ensuring the stability of the mounting plate 61 installed on the front of the sealing plate 5. Moreover, the elastic force of the limiting spring 67 is sufficient to ensure the stability of the locking rod 63 and the positioning rod 611 when the hopper 2 and the filter screen 3 are working.

[0041] Furthermore, the locking assembly 6 also includes a guide rod 68 and a handle. The guide rod 68 is fixedly connected to the inside of the bearing groove 65. The outer wall of the guide rod 68 is slidably inserted and sleeved with the first connecting plate 66 and the second connecting plate 610. The limiting spring 67 is slidably sleeved on the outside of the guide rod 68. The guide rod 68 can ensure the stability of the limiting spring 67 during use. One end of the handle is fixedly connected to the second connecting plate 610. The front of the mounting plate 61 is provided with a sliding hole that matches the handle. After the locking rod 63 is released from the locking state of the positioning plate 62, the handle is used to drive the second connecting plate 610 to descend, so that the second connecting plate 610 drives the positioning rod 611 to separate from the fixed plate 69, and the mounting plate 61 and the sealing plate 5 can be slidably separated.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
