Description

Technical Field

[0001] This utility model relates to structural parts of a general sieve; and to the field of sieve cleaning or heating technology, specifically a high-temperature resistant and wear-resistant silicone ball. Background Technology

[0002] A vibrating screen is an industrial device that uses mechanical vibration to screen, grade, or filter materials. It generates vibration force through a vibrating motor or exciter, thereby achieving the vibration screening of materials. Silica gel balls are special cleaning accessories in vibrating screen equipment. They are mainly used to prevent screen blockage and improve screening efficiency. By continuously bouncing and impacting the screen, they remove materials stuck in the screen holes and prevent screen blockage.

[0003] Adding silicon carbide micropowder during the manufacturing of silicone balls improves their wear resistance. Silicone also possesses high temperature resistance, resulting in silicone balls with both high-temperature resistance and wear resistance. In practice, silicone balls are often solid, molded from a solid core. This solid structure leads to concentrated internal stress distribution, limited deformation space under pressure, and slow elastic recovery, resulting in lower elasticity. Additionally, the weight of the silicone balls is greater, further reducing elasticity and increasing the amount of silicone raw materials required, thus raising production costs. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a high-temperature and wear-resistant silicone ball with the function of setting the inside of the silicone ball as a hollow structure with an elastic mechanism, thereby giving the silicone ball a larger deformation space, enhancing the elastic recovery force, thereby improving the elasticity of the silicone ball, increasing the speed at which the vibrating screen removes screen hole blockages, and thus improving the screening efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-temperature resistant and wear-resistant silicone ball, comprising a first hard silicone layer, a second hard silicone layer connected to the rear side of the first hard silicone layer, and a first soft silicone layer adhered to the inner surface of the first hard silicone layer.

[0006] The inner surface of the second hard silicone layer is glued with a second soft silicone, and the interior of the first soft silicone layer has a first hollow groove.

[0007] The second soft silicone has a second hollow groove inside, and a connecting ball is provided inside the first hollow groove and the second hollow groove;

[0008] Six metal springs are fixedly connected to the outer surface of the connecting ball, and each of the six metal springs has a connecting block fixedly connected to one end of each spring that is far apart from the other.

[0009] Preferably, both the first hard silicone layer and the second hard silicone layer are made of methyl vinyl silicone rubber with added silica, which has high hardness and wear resistance.

[0013] Preferably, the sides of the six connecting blocks that are far apart from each other are all arc-shaped surfaces, and the arc-shaped surfaces of the six connecting blocks are in contact with the inner surfaces of the first hollow groove and the second hollow groove.

[0014] The six connecting blocks are connected to the inner surfaces of the first and second hollow grooves by adhesive bonding.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The high temperature and wear resistant silicone ball can be made into a hollow structure with an elastic mechanism inside the silicone ball, which makes the silicone ball have a larger deformation space, enhances the elastic recovery force, and thus improves the elasticity of the silicone ball, increases the speed of the vibrating screen to remove screen hole blockage, and thus improves the screening efficiency.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0026] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0027] Please see Figure 1-3This utility model provides a new technical solution: a high-temperature resistant and wear-resistant silicone ball, comprising a first hard silicone layer 1, a second hard silicone layer 2 connected to the rear side of the first hard silicone layer 1, both the first hard silicone layer 1 and the second hard silicone layer 2 being made of methyl vinyl silicone rubber with added silica, possessing high hardness and wear resistance; a first soft silicone layer 3 is adhesively bonded to the inner surface of the first hard silicone layer 1, and a second soft silicone layer 4 is adhesively bonded to the inner surface of the second hard silicone layer 2; both the first soft silicone layer 3 and the second soft silicone layer 4 are made of fluorosilicone rubber, possessing softness and resilience; the first hard silicone layer 1 and the second hard silicone layer 2 are bonded together by heat vulcanization, and the first soft silicone layer 3 and the second soft silicone layer 4 are similarly bonded together by heat vulcanization. Overheat vulcanization bonding: The first soft silicone 3 has a first hollow groove 5 inside, and the second soft silicone 4 has a second hollow groove 6 inside. Connecting balls 7 are set inside the first hollow groove 5 and the second hollow groove 6. Six metal springs 8 are fixedly connected to the outer surface of the connecting balls 7. The six metal springs 8 are respectively set at six positions: up and down, front and back, left and right. Connecting blocks 9 are fixedly connected to the ends of the six metal springs 8 that are far apart from each other. The sides of the six connecting blocks 9 that are far apart from each other are all arc-shaped surfaces. The arc-shaped surfaces of the six connecting blocks 9 are in contact with the inner surfaces of the first hollow groove 5 and the second hollow groove 6. The six connecting blocks 9 are connected to the inner surfaces of the first hollow groove 5 and the second hollow groove 6 by adhesive bonding.

[0028] Furthermore, the first hard silicone layer 1 and the second hard silicone layer 2 are made of methyl vinyl silicone rubber with added silica. Silica enhances hardness and wear resistance, while methyl vinyl silicone rubber ensures high-temperature stability. In high-temperature environments (such as industrial screening of high-temperature materials), it can effectively resist wear and extend service life. The first soft silicone layer 3 and the second soft silicone layer 4 are made of fluorosilicone rubber, which combines softness and resilience, and is resistant to oil and chemical corrosion. When subjected to impact, it can absorb energy through its own deformation, reducing the direct impact on the hard silicone layer. The first hollow groove 5 and the second hollow groove 6 provide deformation space for the internal structure. The connecting ball 7 is connected to the connecting block 9 through six metal springs 8. When the silicone ball is subjected to external impact (such as impacting the screen in a vibrating screen), the metal springs 8 are compressed and deformed, absorbing part of the impact force. Subsequently, the springs rebound and release energy, causing the silicone ball to return to its original shape, thus improving the overall elastic performance.

[0029] The arc-shaped surface of the connecting block 9 fits against the inner surface of the hollow groove, limiting the displacement range of the metal spring 8 and preventing it from being damaged by excessive stretching or compression. At the same time, it is fixed by adhesive to ensure the stability of the connection structure under frequent vibration. When the vibrating screen is working, the silicone ball, due to the high wear resistance of the outer layer, can repeatedly impact the screen to remove blockage materials. The elastic structure of the inner layer absorbs the vibration impact force with each impact through the deformation of the metal spring 8 and the fluorosilicone rubber layer, avoiding damage to its own structure and continuously and efficiently completing the auxiliary screening work. In high-temperature mechanical equipment, the outer high-temperature resistant hard silicone layer resists the high temperature of the environment, and the inner elastic structure absorbs the vibration generated by the operation of the equipment, ensuring the stable operation of the equipment and reducing the damage of vibration to the equipment components.

[0030] Furthermore, this method allows the silicone ball to have a hollow structure with an elastic mechanism inside, which in turn gives the silicone ball a larger deformation space, enhances its elastic recovery force, and thus improves the elasticity of the silicone ball. This increases the speed at which the vibrating screen can remove blockages from the screen holes, thereby improving the screening efficiency.

[0031] Structural Description: First Hard Silicone Layer 1: As one of the outer layers of the silicone ball, it is made of methyl vinyl silicone rubber with added silica, possessing high hardness and wear resistance. In high-temperature environments (such as industrial screening of high-temperature materials), it effectively resists wear and extends the service life of the silicone ball.

[0032] The second hard silicone layer 2: also serves as the outer layer structure of the silicone ball, and is made of the same material as the first hard silicone layer 1. It is connected to the first hard silicone layer 1 by heat vulcanization bonding, together forming the outer protective layer of the silicone ball, providing wear resistance and high temperature resistance.

[0033] First soft silicone 3: Adhesive to the inner surface of the first hard silicone layer 1, made of fluorosilicone rubber, possessing softness and resilience. When the silicone ball is impacted, it can absorb energy through its own deformation, reducing direct impact on the hard silicone layer.

[0034] Second soft silicone 4: Adhesive to the inner surface of the second hard silicone layer 2, it is made of the same material as the first soft silicone 3, and also has softness and resilience, further absorbing and dispersing impact force, and protecting the overall structure of the silicone ball.

[0035] First hollow groove 5: It is formed inside the first soft silicone 3 to provide deformation space for the internal structure of the silicone ball, allowing the silicone ball to deform when it is impacted, thereby absorbing and releasing energy.

[0036] Second hollow groove 6: It is formed inside the second soft silicone 4 and together with the first hollow groove 5, it forms the deformation space inside the silicone ball, enhancing the elastic recovery force of the silicone ball.

[0037] Connecting ball 7: Located inside the first hollow groove 5 and the second hollow groove 6, it is connected to the connecting block 9 by six metal springs 8. As the core component of the internal elastic mechanism of the silicone ball, it plays the role of connecting and transmitting force.

[0038] Metal Springs 8: There are six metal springs 8 in total, located at six positions: top and bottom, front and back, left and right, connecting the ball 7 and the connecting block 9. When the silicone ball is impacted, the metal springs 8 compress and deform, absorbing part of the impact force. Then, the springs rebound and release energy, causing the silicone ball to return to its original shape, thus improving the overall elasticity.

[0039] Connecting blocks 9: There are six of them, with their opposite sides being curved surfaces that fit into the inner surfaces of the first hollow groove 5 and the second hollow groove 6. The curved surfaces of the connecting blocks 9 limit the displacement range of the metal spring 8, preventing it from being damaged by excessive stretching or compression. At the same time, they are fixedly connected to the inner surfaces of the first hollow groove 5 and the second hollow groove 6 by adhesive bonding, ensuring the stability of the connection structure under frequent vibration.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
