Description

Technical Field

[0001] This utility model relates to the field of material sieve plate technology, specifically a highly durable rubber sieve plate structure. Background Technology

[0002] With the development of technology and the needs of life, the development of rubber products has been greatly promoted. Common rubber products in life include tires, wire and cable sheaths, and underground pipelines. As technology develops, rubber products are becoming more and more diverse. They can not only be used as products, but also as tools to facilitate our work. For example, the emergence of rubber screens has not only improved work efficiency, but more importantly, rubber screens are more adaptable to materials than screens made of ordinary materials. Therefore, plastic screens have a longer service life, and rubber screens also have a good self-cleaning function.

[0003] Chinese Utility Model Patent Publication No. CN210411517U discloses a highly durable rubber screen structure. This highly durable rubber screen structure, with its rubber outer sheath and frame, improves ease of use. During assembly, the rubber outer sheath is first placed on top of the frame, with the opening at the bottom of the sheath aligned with the horizontal and vertical ribs of the frame. Then, the sheath is pressed down forcefully, causing each part of the frame to embed into the hollow groove in the middle of the rubber outer sheath. However, while this highly durable rubber screen structure allows for quick replacement of the rubber outer sheath, it does not facilitate double-sided use of the rubber screen, resulting in significant limitations in its application and higher costs, thus hindering its widespread adoption. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a highly durable rubber screen structure, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a highly durable rubber screen plate structure, including a screen plate frame and a screening plate. A reinforcing rib is fixedly installed along the inner edge of the screen plate frame. An outer frame is fixedly installed at the end of the screen plate frame away from the screening plate. A protective sleeve is fixedly installed at the end of the outer frame near the reinforcing rib. An outer coating is applied to the end of the outer frame away from the screen plate frame. A reserved groove of the same size as the screening plate is opened at the end of the screen plate frame near the screening plate.

[0006] Preferably, there are multiple identical reserved slots and screening plates, and the multiple reserved slots and screening plates are distributed at equal intervals with respect to the screen plate frame.

[0007] Through the above technical solution, by combining the reserved slot 2 with the screening plate, the material can enter the screening tank through the reserved slot 2 when the whole screening body is in use, which facilitates subsequent screening.

[0008] Preferably, the screening plate has a screening groove extending from top to bottom, and the screening groove has a "regular hexagonal" cross-section.

[0009] With the above technical solution, during screening, the material falls from above the screening plate into the screening trough. The inclined sidewalls of the regular hexagonal cross-section guide the material to slide down for screening. Screening troughs of different diameters can be selected according to the actual situation. Subsequently, materials of different particle sizes are classified through the gaps in the screening trough. Materials that meet the particle size requirements are discharged from below, completing the screening work. The regular hexagonal structure of the screening trough, with its rounded edges and corners, reduces material jamming and screen hole clogging.

[0010] Preferably, the reinforcing ribs are arranged in a cross shape, and a reserved groove is provided on the side of the protective sleeve near the reinforcing ribs, the reserved groove being adapted to the reinforcing ribs.

[0011] Through the above technical solution, by designing reinforcing ribs, a cross-shaped reinforcing rib is pre-cast along the inner edge of the screen plate frame to form a grid-like support structure. Then, the reserved groove of the protective sleeve is aligned with the reinforcing rib and embedded by hot melting. The cross-shaped reinforcing rib can enhance the overall rigidity of the screen plate frame and reduce vibration deformation. The protective sleeve wraps around the reinforcing rib through the reserved groove to prevent it from directly contacting the material and causing wear, thus extending the structural life.

[0012] Preferably, the outer coating has a through groove at one end near the sieve plate frame, and the through groove and the reserved groove are the same size.

[0013] With the above technical solution, when the screening plate is installed, its edge can be embedded into the reserved groove 2 through the through groove to achieve a seamless connection between the outer coating and the screening plate. The through groove and the reserved groove 2 work together to make the outer coating cover the edge of the screening plate, avoiding the aging of the connection due to exposure, thus affecting its service life.

[0014] Preferably, the sieve frame and reinforcing ribs are made of polyurethane material, and the sieve frame, outer frame and outer coating are the same size.

[0015] The above technical solution involves coating the outer side of the outer frame with an outer coating of the same size as the sieve plate frame, covering the entire surface of the outer frame. Through the cooperation of the sieve plate frame, the outer frame, and the outer coating, the outer frame can also be protected, thereby improving the service life of the outer frame.

[0016] Preferably, the outer coating is an epoxy resin coating, and the outer frame and the outer coating are located at the upper and lower ends of the center line of the sieve plate frame, respectively.

[0017] Through the above technical solutions, the high hardness and corrosion resistance of the epoxy resin coating can effectively protect the outer frame from material impact and chemical erosion. The symmetrically distributed outer frame and outer coating make the screen plate as a whole balanced in terms of force, improve the stability during the vibrating screening process, and make the structure on both sides of the screen plate the same. When one side is worn more, the other side can be replaced for use, thereby improving its service life and making it easy to promote and use.

[0018] Compared with the prior art, this utility model provides a highly durable rubber screen structure with the following advantages:

[0019] 1. The highly durable rubber screen plate structure, with its hexagonal screening trough and rounded corners, reduces material jamming and screen hole clogging. The screen plate frame, outer frame and outer coating work together to protect the outer frame, thereby improving the service life of the outer frame.

[0020] 2. The highly durable rubber screen plate structure features a symmetrically distributed outer frame and outer coating that balances the overall force on the screen plate, improving stability during vibrating screening. Furthermore, the identical structure on both sides of the screen plate allows for replacement of the other side when one side experiences significant wear, thus extending its service life, reducing costs, and facilitating widespread adoption. The "+" shaped reinforcing ribs enhance the overall rigidity of the screen plate frame, reducing vibration deformation. A protective sleeve, with a pre-drilled groove, wraps around the reinforcing ribs to prevent direct contact with materials and thus prevent wear, extending the structural lifespan.

[0029] 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.

[0030] Example 1: As Figure 1-7 As shown, the present invention provides a high-durability rubber sieve structure, including a sieve frame 1 and a sieve plate 9. A reinforcing rib 2 is fixedly installed along the inner edge of the sieve frame 1. An outer frame 3 is fixedly installed at the end of the sieve frame 1 away from the sieve plate 9. A protective sleeve 4 is fixedly installed at the end of the outer frame 3 near the reinforcing rib 2. An outer coating 6 is applied to the end of the outer frame 3 away from the sieve frame 1. A reserved groove 8 of the same size as the sieve plate 9 is opened at the end of the sieve frame 1 near the sieve plate 9.

[0031] Specifically, multiple reserved slots 2 8 and screening plates 9 are provided. The multiple reserved slots 2 8 and screening plates 9 are distributed at equal intervals about the screen plate frame 1. The advantage is that, through the cooperation of reserved slots 2 8 and screening plates 9, the material can enter the screening tank 10 through reserved slots 2 8 when the whole screening body is in use, which facilitates subsequent screening.

[0032] Specifically, the screening plate 9 has a screening trough 10 extending from top to bottom. The screening trough 10 has a "regular hexagonal" cross-section. The advantage is that during screening, the material falls from the top of the screening plate 9 into the screening trough 10. The inclined sidewalls of the regular hexagonal cross-section guide the material to slide down for screening. Screening troughs 10 of different diameters can be selected according to the actual situation. Then, materials of different particle sizes are classified through the gaps in the screening trough 10. Materials that meet the particle size requirements are discharged from the bottom, completing the screening work. The regular hexagonal structure of the screening trough 10 reduces material jamming and screen hole clogging due to its rounded corners.

[0033] Specifically, the reinforcing ribs 2 are arranged in a cross shape. The protective sleeve 4 has a reserved groove 5 on the side near the reinforcing ribs 2. The reserved groove 5 is adapted to the reinforcing ribs 2. The advantage is that, through the design of the reinforcing ribs 2, the cross-shaped reinforcing ribs 2 are pre-cast inside the screen frame 1 to form a grid-like support structure. Then, the reserved groove 5 of the protective sleeve 4 is aligned with the reinforcing ribs 2 and embedded by hot melting. The cross-shaped reinforcing ribs 2 can enhance the overall rigidity of the screen frame 1 and reduce vibration deformation. The protective sleeve 4 wraps the reinforcing ribs 2 through the reserved groove 5 to prevent them from directly contacting the material and causing wear, thus extending the service life of the structure.

[0034] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0035] Specifically, the outer coating 6 has a through groove 7 at one end near the screen plate frame 1. The through groove 7 and the reserved groove 8 are the same size. The advantage is that when the screening plate 9 is installed, its edge can be embedded into the reserved groove 8 through the through groove 7, so as to achieve a seamless connection between the outer coating 6 and the screening plate 9. The through groove 7 and the reserved groove 8 cooperate to make the outer coating 6 cover the edge of the screening plate 9, so as to avoid the aging of the connection due to exposure, thereby affecting its service life.

[0036] Specifically, the sieve frame 1 and the reinforcing rib 2 are both made of polyurethane material. The sieve frame 1, the outer frame 3 and the outer coating 6 are the same size. The advantage is that the outer coating 6, which is the same size as the sieve frame 1, is coated on the outside of the outer frame 3, covering the entire surface of the outer frame 3. Through the cooperation of the sieve frame 1, the outer frame 3 and the outer coating 6, the outer frame 3 can also be protected, thereby improving the service life of the outer frame 3.

[0037] Specifically, the outer coating 6 is an epoxy resin coating. The outer frame 3 and the outer coating 6 are located at the upper and lower ends of the center line of the screen plate frame 1, respectively. The advantages are that the high hardness and corrosion resistance of the epoxy resin coating can effectively protect the outer frame 3 from material impact and chemical erosion. The symmetrically distributed outer frame 3 and outer coating 6 make the screen plate as a whole balanced in force, improve the stability during the vibrating screening process, and make the structure on both sides of the screen plate the same. When one side is worn more, the other side can be replaced for use, thereby improving its service life and facilitating its widespread use.

[0038] Working Principle: During use, material falls from above the screening plate 9 into the screening trough 10. The inclined sidewalls of the hexagonal cross-section guide the material downwards for screening. Screening troughs 10 of different diameters can be selected according to actual conditions. Materials of different particle sizes are then classified through the gaps in the screening trough 10. Materials matching the particle size are discharged from below, completing the screening process. The hexagonal structure of the screening trough 10, with its rounded edges, reduces material jamming and screen blockage. The design of reinforcing ribs 2 involves pre-cast cross-shaped reinforcing ribs 2 within the screen plate frame 1, forming a grid-like support structure. Then, the pre-reserved groove 5 of the protective sleeve 4 is aligned with and embedded into the reinforcing ribs 2 via hot-melt welding. The cross-shaped reinforcing ribs 2 enhance the overall rigidity of the screen plate frame 1, reducing vibration deformation. The protective sleeve 4 wraps around the reinforcing ribs 2 through the pre-reserved groove 5, preventing direct contact with the material and thus extending the structural lifespan. Screening plate 9 installation... At the same time, its edge can be embedded into the reserved groove 8 through the through groove 7 to achieve a seamless connection between the outer coating 6 and the screening plate 9. The through groove 7 and the reserved groove 8 cooperate to make the outer coating 6 cover the edge of the screening plate 9, avoiding the aging of the connection due to exposure, thus affecting its service life. The outer frame 3 is coated with an outer coating 6 of the same size as the screen plate frame 1, covering the entire surface of the outer frame 3. Through the cooperation of the screen plate frame 1, the outer frame 3 and the outer coating 6, the outer frame 3 can also be protected, thereby improving the service life of the outer frame 3. The high hardness and corrosion resistance of the epoxy resin coating can effectively protect the outer frame 3 from material impact and chemical erosion. The symmetrically distributed outer frame 3 and outer coating 6 make the screen plate as a whole balanced in force, improve the stability during the vibrating screening process, and make the structure on both sides of the screen plate the same. When one side is worn more, the other side can be replaced for use, thereby improving its service life and facilitating its widespread use.
