[0021] The specific embodiments of this application will be described in more detail below with reference to the accompanying drawings, which illustrate representative embodiments of this application and are not intended to limit this application.

[0022] like Figure 1 As shown, this application provides a roller screen plate 1, which is installed on a roller screen. The roller screen is used in industries such as mining, power, coal, and building materials for screening bulk solid materials. For example, the material can be coal, and the roller screen screens coal. The roller screen includes a screen shaft that can rotate, thereby converting electrical energy into mechanical energy. The screen shaft rotates about its axial direction. The direction of rotation of the screen shaft is the same as the direction of material movement. The screen shaft can rotate clockwise to move at least a portion of the material. Optionally, the screen shaft is made of 45# steel to provide a certain structural strength.

[0023] The screen shaft is connected to the roller screen plate 1. The roller screen plate 1 is sleeved on the outside of the screen shaft. The screen shaft passes through the roller screen plate 1 along its axial direction. The screen shaft and the roller screen plate 1 are arranged coaxially. The axial direction of the screen shaft is parallel to the axial direction of the roller screen plate 1. Preferably, the screen shaft passes through the center of the roller screen plate 1. Rotation of the screen shaft can drive the roller screen plate 1 to rotate. The roller screen plate 1 can rotate around the axial direction of the screen shaft. In this way, the roller screen plate 1 can rotate under the drive of the screen shaft.

[0024] Furthermore, the roller screen plate 1 includes a screen plate body 10, which is used to connect with a screen shaft. The screen plate body 10 is provided with a shaft hole 101, which is located at the center of the screen plate body 10. The shaft hole 101 extends through the screen plate body 10 along the axial direction. The screen shaft can be inserted into the shaft hole 101 so that the screen shaft is connected to the screen plate body 10. Optionally, the screen shaft and the screen plate body 10 can be tightly connected together by an interference fit.

[0025] The rotation of the screen shaft can drive the screen plate body 10 to rotate. The screen plate body 10 can rotate about its axial direction. The screen shaft can drive the screen plate body 10 to rotate clockwise. Optionally, the screen plate body 10 can be made of 45# steel to have a certain structural strength.

[0026] The roller screen plate 1 also includes a protruding component 20, which is connected to the screen plate body 10. The protruding component 20 protrudes from the screen plate body 10. The protruding component 20 protrudes outward from the outer peripheral surface of the screen plate body 10. The protruding component 20 protrudes outward along the radial direction of the screen plate body 10. The protruding component 20 is closer to the outside of the roller screen plate 1 than the screen plate body 10 along the radial direction. Optionally, the protruding component 20 and the screen plate body 10 can be connected by a connector so that the protruding component 20 is tightly connected to the screen plate body 10.

[0027] For example, the screen body 10 includes a first positioning hole, the axial direction of which is parallel to the axial direction of the screen body 10. The protruding component 20 includes a second positioning hole, the axial direction of which is parallel to the axial direction of the screen body 10. The first positioning hole and the second positioning hole correspond to each other along the axial direction of the screen body 10. A connector can be inserted into the first positioning hole and the second positioning hole to connect the protruding component 20 to the screen body 10. Optionally, the connector is a bolt, and both the first positioning hole and the second positioning hole are threaded holes. The connector is threadedly connected to the first positioning hole. The connector is threadedly connected to the second positioning hole. In this way, the protruding component 20 and the screen body 10 can be tightly connected.

[0028] The rotation of the screen body 10 drives the protruding component 20 to rotate. The screen shaft drives the protruding component 20 to rotate around the axial direction of the screen body 10 via the screen body 10. When the screen shaft rotates clockwise, both the screen body 10 and the protruding component 20 rotate clockwise.

[0029] The protruding component 20 is in direct contact with the material. Optionally, the protruding component 20 can be made of wear-resistant 500 steel plate to provide structural strength and wear resistance. This allows the protruding component 20 to effectively resist the impact, friction, and compression of the material, preventing it from breaking due to excessive force. This reduces the frequency of replacement, lowers the workload and cost of manual maintenance, maintains stable screening accuracy, and effectively improves the continuous operating efficiency of the roller screen.

[0030] The protruding assembly 20 includes at least two protruding members 201, which are spaced apart along the circumferential direction of the shaft hole 101. Both protruding members 201 are located outside the screen body 10 along the radial direction of the screen body 10. The protruding members 201 protrude outwards along the radial direction of the screen body 10. Preferably, the protruding members 201 are identical in construction. The at least two protruding members 201 are equidistantly arranged along the circumferential direction of the screen body 10.

[0031] The rotation of the screen body 10 can drive at least two protruding members 201 to rotate. Each of the at least two protruding members 201 can rotate about the axial direction of the screen body 10. Each of the at least two protruding members 201 can rotate about the circumference of the screen body 10. Each of the at least two protruding members 201 can rotate synchronously in a clockwise direction. Optionally, the protruding members 201 can be made of wear-resistant 500 steel plate to provide a certain structural strength and wear resistance.

[0032] For example, the protruding component 20 includes 10 protruding members 201, which are equidistantly arranged along the circumferential direction of the screen body 10. The protruding component 20 is constructed as a ten-tooth multi-curved involute structure. During the rotation of the screen shaft, each rotation of the screen shaft generates ten periodic projectile actions on the material, accelerating the material's movement speed, achieving material stratification, enhancing the material's screening performance, and improving screening efficiency. In particular, when processing coal with high moisture content, the roller screen 1 of this application can avoid material adhesion and reduce clogging through high-frequency projectile action, resulting in a particularly outstanding screening effect.

[0033] Furthermore, the protruding member 201 also includes a first involute segment 2011, a second involute segment 2012, and a straight segment 2013, all located on the outer surface of the protruding member 201. The first involute segment 2011 and the second involute segment 2012 are spaced apart. Both the first involute segment 2011 and the second involute segment 2012 extend outward along the radial direction of the sieve body 10. The straight segment 2013 is located between the first involute segment 2011 and the second involute segment 2012. The straight segment 2013 is located between the first involute segment 2011 and the second involute segment 2012 along the circumferential direction of the shaft hole 101. One end of the straight segment 2013 is connected to the first involute segment 2011, and the other end of the straight segment 2013 is connected to the second involute segment 2012.

[0034] The first involute segment 2011 intersects with the straight segment 2013. The first involute segment 2011 is connected to the straight segment 2013. The included angle between the first involute segment 2011 and the straight segment 2013 is an obtuse angle. The second involute segment 2012 is connected to the straight segment 2013. The included angle between the second involute segment 2012 and the straight segment 2013 is an acute angle. Thus, the protruding member 201 has an acute angle and an obtuse angle respectively along the radial edge of the sieve body 10. The acute angle and the obtuse angle are located at the two ends of the straight segment 2013.

[0035] When the protruding member 201 rotates clockwise, the first involute segment 2011, the second involute segment 2012, and the straight segment 2013 rotate synchronously in the clockwise direction, and the acute angle and the obtuse angle rotate synchronously in the clockwise direction.

[0036] like Figure 1 As shown, when the screen shaft rotates clockwise, both the screen body 10 and the protruding assembly 20 rotate clockwise. The material moves from the upper feed port to the lower discharge port. The material preferentially contacts the protruding assembly 20. The material can collide with the protruding member 201 to screen the material.

[0037] For example, the first involute segment 2011 and the straight segment 2013 work together to apply an upward force to the material, causing it to be thrown upwards and then fall downwards under the influence of gravity. During this process, the direction of material flow is the same as the direction of screen shaft rotation. The material moves in a parabolic motion. The upward throwing of the material separates large pieces from small pieces. In this embodiment, "large pieces" refers to materials whose size is larger than the gap between the roller screen plate 1 and the adjacent screen shaft along the radial direction of the screen body 10. Large pieces cannot enter below the roller screen plate 1. Small pieces are smaller than the large pieces and enter below the roller screen plate 1. Large pieces can be thrown upwards again under the action of the first involute segment 2011 and the straight segment 2013 to achieve material screening. In this embodiment, "down" refers to the direction towards the bottom of the roller screen plate 1, and "up" refers to the direction towards the top of the roller screen plate 1.

[0038] In this way, the first involute segment 2011 and the straight segment 2013 work together to project the material, reducing its stickiness and preventing the protruding component 20 from adhering to the material, thus improving anti-clogging performance. Furthermore, when the obtuse angle collides with the material, it can directly apply an upward force to project the material upward, separating large pieces from small pieces and improving screening efficiency.

[0039] For example, the acute angle formed by the second involute segment 2012 and the straight segment 2013 can loosen the material layer to disrupt its structure, separating large pieces from small pieces. Small pieces can then enter the gap between two adjacent protruding members 201. Furthermore, when the acute angle collides with the material, it applies a force to the material, effectively breaking it under concentrated impact and shear forces, or separating adhered materials.

[0040] In this way, the second involute segment 2012 works in conjunction with the straight segment 2013 to prioritize the screening of materials. By loosening the material layer, it achieves a good unblocking effect, preventing materials from directly entering the gap between two adjacent protruding components 201 and reducing the probability of material accumulation.

[0041] Simultaneously, when material falls directly onto the protruding component 20, the protruding component 20 can cause small pieces of material to rotate clockwise. For example, when material directly contacts the second involute segment 2012, the second involute segment 2012 can cause the small pieces of material to rotate clockwise, and then smoothly fall onto the conveyor belt below via the first involute segment 2011. In this way, large pieces of material can be thrown upwards through the protruding component 20, and small pieces of material can fall downwards through the protruding component 20, thus achieving material screening.

[0042] The protruding component 20 can disperse the material into the gap between at least two adjacent protruding members 201, avoiding blockage caused by material concentration and clearing the blockage layer. Furthermore, the protruding component 20 can repeatedly throw the material upwards, effectively breaking down the material's adhesiveness, effectively preventing blockage, improving material dispersion, enhancing the anti-clogging performance of the roller screen plate 1, reducing the amount of manual cleaning work, and lowering the labor intensity of operators.

[0043] Furthermore, the roller screen plate 1 can also be used in conjunction with other equipment to clear material blockages. For example, the roller screen plate 1 can work with other equipment to clean the mud accumulation points of other equipment through the protruding components 20, allowing the other equipment to operate more smoothly. Additionally, the roller screen plate 1 can also be used to clean adjacent screen shafts of the same roller screen, clearing blockages and allowing adjacent screen shafts to operate smoothly.

[0044] According to the roller screen plate 1 of this application, the roller screen plate 1 includes a screen plate body 10 and a protruding component 20. The screen plate body 10 is provided with a shaft hole 101. The protruding component 20 protrudes outward from the outer peripheral surface of the screen plate body 10. The protruding component 20 includes at least two protruding members 201. The at least two protruding members 201 are arranged at intervals along the circumferential direction of the screen plate body 10. The protruding member 201 also includes a first involute segment 2011, a second involute segment 2012 and a straight segment 2013. The straight segment 2013 is located between the first involute segment 2011 and the second involute segment 2012. The included angle between the first involute segment 2011 and the straight segment 2013 is an obtuse angle, and the included angle between the second involute segment 2012 and the straight segment 2013 is an acute angle. In this way, the screen body 10 and the protruding component 20 cooperate. The rotation of the screen body 10 can drive the protruding component 20 to rotate. The protruding component 20 can throw the material upward to reduce the adhesion of the material, prevent the protruding component 20 from sticking to the material, and improve the anti-clogging performance. It can also effectively crush the material or peel off the sticky material, preventing the material from directly entering the gap between two adjacent protruding components 201. It can loosen the material layer, destroy the structure of the material layer, separate large pieces of material from small pieces of material, play a good role in loosening the blockage, clear the blockage layer, and reduce the amount of manual cleaning work. In addition, the protruding component 20 can also assist other equipment in completing the mud cleaning operation, ensuring the smooth operation of the equipment.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, the protruding assembly 20 also includes an annular member 202, which is located between the screen body 10 and at least two protruding members 201. The annular member 202 connects the screen body 10 and the at least two protruding members 201. The annular member 202 is constructed in a generally annular shape. The screen body 10 is located inside the annular member 202 along the radial direction of the screen body 10. The at least two protruding members 201 are located outside the annular member 202 along the radial direction of the screen body 10. Optionally, the annular member 202 can be connected to the screen body 10 by a connector to achieve good structural strength.

[0046] At least two protruding members 201 are connected to the annular member 202. The at least two protruding members 201 are spaced apart along the circumferential direction of the annular member 202. The annular member 202 is coaxially arranged with the screen body 10. The circumferential direction of the annular member 202 is parallel to the circumferential direction of the screen body 10. The axial direction of the screen body 10 is parallel to the axial direction of the annular member 202. Preferably, the annular member 202 and the protruding members 201 are integrally formed to have good structural strength. Rotation of the annular member 202 can drive the at least two protruding members 201 to rotate synchronously.

[0047] The screen body 10, via the annular component 202, can drive at least two protruding components 201 to rotate synchronously. Both the annular component 202 and the at least two protruding components 201 can come into contact with the material. The at least two protruding components 201 are closer to the material than the annular component 202. Optionally, the annular component 202 can be made of wear-resistant 500 steel plate to provide a certain structural strength and wear resistance. In this way, the annular component 202 can effectively resist the impact and wear of the material, continuously ensure the stability of the material screening accuracy, extend its service life, reduce material blockage, equipment jamming and other failures, and improve the stability and safety of equipment operation.

[0048] The annular component 202 includes arc segments 2021, which are located on the outer circumferential surface of the annular component 202 along the radial direction of the annular component 202. The arc segments 2021 are located between adjacent protruding components 201. The annular component 202 is provided with multiple arc segments 2021. The multiple arc segments 2021 are spaced apart along the circumferential direction of the annular component 202. Preferably, the multiple arc segments 2021 are spaced at the same distance from each other. The multiple arc segments 2021 are equidistantly arranged along the circumferential direction of the annular component 202. The curvature of the arc segments 2021 is uniform, and the curvature of each point on the same arc segment 2021 is the same. Thus, the multiple arc segments 2021 have the same length and curvature, resulting in a more balanced force on the material. This allows the material to move along the same projection path, resulting in a more stable trajectory, reducing problems such as jamming and accumulation, and ensuring the stability of the material screening accuracy.

[0049] The arc segment 2021 includes a first end 2022 and a second end 2023, which are located at opposite ends of the arc segment 2021. The first end 2022 is connected to a first involute segment 2011 of a protruding member 201, and the second end 2023 is connected to a second involute segment 2012 of another protruding member 201. In this way, one protruding member 201 can be connected to another protruding member 201 through the arc segment 2021.

[0050] A straight segment 2013 connects the first involute segment 2011 and the second involute segment 2012 of the same protruding member 201. An arc segment 2021 connects the first involute segment 2011 and the second involute segment 2012 of two adjacent protruding members 201. The first involute segment 2011 and the second involute segment 2012 are spaced apart and are arranged alternately along the circumferential direction of the annular member 202. The straight segment 2013 and the arc segment 2021 are also spaced apart and are arranged alternately along the circumferential direction of the annular member 202. Thus, the first involute segment 2011, the straight segment 2013, the second involute segment 2012, and the arc segment 2021 are arranged alternately along the circumferential direction of the annular member 202. The arc segment 2021 approximates a straight line shape. The arc segment 2021 is approximately parallel to the straight segment 2013. The lengths of the straight segment 2013 and the arc segment 2021 along the circumferential direction of the shaft hole 101 are approximately the same. Preferably, the lengths of the straight segment 2013 and the arc segment 2021 along the circumferential direction of the shaft hole 101 are the same.

[0051] A groove 203 is formed between adjacent protruding members 201. The protruding assembly 20 includes at least two grooves 203, which are alternately arranged with at least two protruding members 201. The at least two grooves 203 and at least two protruding members 201 are alternately arranged about the axial direction of the shaft hole 101. The at least two grooves 203 are spaced apart about the axial direction of the shaft hole 101. The at least two grooves 203 are spaced apart along the circumferential direction of the shaft hole 101. Preferably, the grooves 203 are evenly spaced. The at least two grooves 203 are equidistantly arranged along the circumferential direction of the shaft hole 101.

[0052] The groove 203 opens towards the outside of the roller screen plate 1 along the radial direction of the shaft hole 101. The groove 203 is located between two adjacent protruding members 201 along the circumferential direction of the shaft hole 101. In this way, the groove 203 can guide the flow direction of the material, prevent the material from accumulating inside the groove 203, reduce material retention, and improve the screening effect; when there is residual material or impurities on the protruding member 20, other equipment can also directly clean the blocked material through the groove 203, which improves the anti-clogging performance of the roller screen plate 1 and makes the operation of the roller screen plate 1 smoother.

[0053] like Figure 2As shown, the groove 203 includes a first sidewall 2031, a second sidewall 2032, and a bottom wall 2033. The first sidewall 2031 is connected to the second sidewall 2032 via the bottom wall 2033. The first sidewall 2031 and the second sidewall 2032 are spaced apart. The bottom wall 2033 is located between the first sidewall 2031 and the second sidewall 2032. One end of the bottom wall 2033 is connected to the first sidewall 2031, and the other end is connected to the second sidewall 2032. The first sidewall 2031 is formed by a first involute segment 2011 of a protruding member 201, the second sidewall 2032 is formed by a second involute segment 2012 of another protruding member 201, and the bottom wall 2033 is formed by an arc segment 2021. Thus, the protruding member 201 and the groove 203 are alternately arranged along the circumferential direction of the annular member 202.

[0054] The protruding member 201 and the groove 203 can alternately contact the material. By controlling the gap between the protruding member 201 and the groove 203, the protruding assembly 20 can ensure the particle size of the material being screened and improve screening accuracy. Through the cooperation of the protruding member 201 and the groove 203, the protruding assembly 20 can disperse the force exerted by the material on the protruding assembly 20, allowing the material to move in an orderly manner, effectively reducing the adhesion of the material, avoiding accumulation, and clearing blockage layers. This improves the anti-clogging performance of the protruding assembly 20, reduces the amount of manual cleaning work, increases equipment processing efficiency, extends equipment service life, and ensures operational stability.

[0055] like Figure 4 As shown, the dimension of the protruding component 20 along the axial direction of the screen body 10 is smaller than the dimension of the screen body 10 along the axial direction of the screen body 10.

[0056] As an optional implementation, the protruding component 20 is located on the central axis of the screen body 10 along the axial direction of the screen body 10. In this way, the screen body 10 can uniformly support the protruding component 20 to offset the pressure and vibration stress borne by the protruding component 20 during contact with the material, and prevent uneven stress on the protruding component 20; it can also disperse the impact force applied to the protruding component 20 by the material, and avoid the protruding component 20 from being broken due to excessive local stress.

[0057] In another optional implementation, the roller screen plate 1 includes two screen plate bodies 10, which are symmetrically arranged at both ends of the protruding component 20. The two screen plate bodies 10 are located at both ends of the protruding component 20 along the axial direction of the screen plate bodies 10. Preferably, the two screen plate bodies 10 have identical structures. Both screen plate bodies 10 are connected to the protruding component 20 by connecting members. The rotation of the screen shaft can drive the two screen plate bodies 10 to rotate synchronously with the protruding component 20. In this way, the two screen plate bodies 10 can provide uniform support for the protruding component 20 to offset the pressure and vibration stress borne by the protruding component 20 during contact with the material, preventing uneven force on the protruding component 20; it can also disperse the impact force applied to the protruding component 20 by the material, avoiding excessive local stress on the protruding component 20 and breakage.

[0058] like Figure 2 , Figure 3 and Figure 4 As shown, the screen body 10 includes a stepped member 102, which is located outside the screen body 10 along the radial direction of the shaft hole 101. The stepped member 102 is connected to the protruding assembly 20. The stepped member 102 protrudes from the protruding assembly 20 along the axial direction of the shaft hole 101. Preferably, the protruding assembly 20 is located at the center of the stepped member 102 along the axial direction of the shaft hole 101.

[0059] The stepped member 102 can reinforce the protruding component 20 so that the stepped member 102 and the protruding component 20 are tightly connected. Optionally, the stepped member 102 and the protruding component 20 can be connected together by a connector. In this way, when the screen body 10 rotates, the stepped member 102 can drive the protruding component 20 to rotate.

[0060] The stepped component 102 includes a first stepped portion 1021, which protrudes from the protruding assembly 20. The first stepped portion 1021 protrudes outward from the end surface of the protruding assembly 20. The first stepped portion 1021 protrudes outward along the axial direction of the shaft hole 101. The end surface of the protruding assembly 20 is perpendicular to the axial direction of the shaft hole 101. In this way, the first stepped portion 1021 can prevent materials or impurities from entering the gap between the first stepped portion 1021 and the protruding assembly 20, so that the first stepped portion 1021 and the protruding assembly 20 are tightly connected, reducing the risk of failures such as jamming and wear. Optionally, the first stepped portion 1021 and the protruding assembly 20 can be connected together by a connector.

[0061] The stepped component 102 also includes a second stepped portion 1022, which protrudes from the first stepped portion 1021. The second stepped portion 1022 protrudes outward from the end surface of the first stepped portion 1021. The second stepped portion 1022 protrudes outward along the axial direction of the shaft hole 101. The end surface of the first stepped portion 1021 is perpendicular to the axial direction of the shaft hole 101. In this way, the second stepped portion 1022 can improve the connection strength between the first stepped portion 1021 and the protruding component 20, enhance the radial deformation resistance of the protruding component 20, effectively disperse the radial load transmitted to the protruding component 20, and prevent the protruding component 20 from cracking or plastic deformation due to excessive local stress, so that the protruding component 20 can operate stably and smoothly.

[0062] The dimension of the second step portion 1022 in the radial direction along the shaft hole 101 is smaller than that of the first step portion 1021. This strengthens the structure, avoids affecting the screen shaft, and makes the operation of the protruding assembly 20 smoother.

[0063] The stepped component 102 also includes a third stepped portion 1023, which is spaced apart from the second stepped portion 1022 along the axial direction of the shaft hole 101. The third stepped portion 1023 protrudes outward along the radial direction of the shaft hole 101. The third stepped portion 1023 protrudes beyond the second stepped portion 1022. The third stepped portion 1023 protrudes outward along the axial direction of the shaft hole 101. In this way, the third stepped portion 1023 can improve the connection between the screen plate body 10 and the screen shaft, enhance the radial deformation resistance of the screen plate body 10, effectively disperse the radial load transmitted by the screen shaft, and prevent the screen plate body 10 from cracking or plastic deformation due to excessive local stress.

[0064] The stepped member 102 also includes an extension 1024, which is located between the second stepped portion 1022 and the third stepped portion 1023. The extension 1024 connects the second stepped portion 1022 and the third stepped portion 1023 along the axial direction of the shaft hole 101. The radial dimension of the extension 1024 is smaller than that of the second stepped portion 1022, and the radial dimension of the extension 1024 is smaller than that of the third stepped portion 1023. In this way, the second stepped portion 1022, the third stepped portion 1023, and the extension 1024 can form a groove, which can cooperate with the bearing to ensure the smooth rotation of the roller screen plate 1.

[0065] In embodiments of this disclosure, such as Figure 3As shown, the sieve plate body 10 also includes an axial groove 103, which communicates with and protrudes from the shaft hole 101. The axial groove 103 protrudes outward along the radial direction of the shaft hole 101. The axial groove 103 protrudes outward in a direction away from the shaft hole 101. The axial groove 103 is closer to the outside of the sieve plate body 10 in the radial direction than the shaft hole 101. The dimension of the axial groove 103 in the axial direction of the sieve plate body 10 is the same as the dimension of the shaft hole 101 in the axial direction of the sieve plate body 10.

[0066] The screen shaft is provided with a protrusion that extends radially outward from the outer circumferential surface of the screen shaft. Preferably, the dimension of the protrusion along the axial direction of the screen shaft is the same as the dimension of the screen shaft along the axial direction. The protrusion can be inserted into the axial groove 103 so that the screen shaft can be inserted into the shaft hole 101.

[0067] The axial groove 103 engages with the protrusion. When the screen shaft rotates, the protrusion drives the axial groove 103 and the shaft hole 101 to rotate synchronously, thereby causing the screen plate body 10 to rotate. The axial groove 103 restricts the displacement of the protrusion along the circumferential direction of the screen plate body 10. In this way, during rotation, the screen plate body 10 is fixed and engaged with the screen shaft.

[0068] Optionally, the axial groove 103 is inclinedly disposed inside the screen body 10. When the roller screen 1 is in operation, material may enter the axial groove 103 to form strip-shaped slurry. The dimensions of the two ends of the axial groove 103 along the axial direction of the screen body 10 are different. The axial direction of the axial groove 103 intersects the axial direction of the screen body 10. Specifically, as... Figure 1 As shown, the axial groove 103 includes a first guide end 1031 and a second guide end 1032, which are located at opposite ends of the axial groove 103 along the axial direction of the screen body 10. The first guide end 1031 protrudes from the shaft hole 101 in the radial direction of the screen body 10 by a larger dimension than the second guide end 1032 protrudes from the shaft hole 101 in the radial direction of the screen body 10. This allows the axial direction of the axial groove 103 to form an inclination angle with the axial direction of the screen body 10. When the roller screen 1 stops operating and is removed from the screen shaft for cleaning, the inclined arrangement of the axial groove 103 facilitates the cleaning of strip-shaped slurry by the operator. For example, if the operator collides the screen body 10 with another object, the first guide end 1031 will be closer to the other object than the second guide end 1032, allowing the strip-shaped slurry to flow smoothly from the second guide end 1032 to the first guide end 1031. Alternatively, the axial groove 103 can also be cleaned of the strip-shaped mud inside the axial groove 103 by other equipment.

[0069] In this way, the roller screen plate 1, through the cooperation of the screen plate body 10 and the protruding component 20, can stably screen materials, ensure the stability of the material screening particle size, have good anti-clogging performance, avoid bending and deformation of the screen shaft due to clogging, reduce the workload of manual clogging, and can also assist other equipment in completing mud cleaning operations.

[0070] This application discloses a roller screen plate 1, which includes a screen plate body 10 and a protruding component 20. The rotation of the screen plate body 10 can drive the protruding component 20 to rotate. The protruding component 20 includes an annular component 202 and at least two protruding components 201. The at least two protruding components 201 are arranged at intervals along the circumferential direction of the screen plate body 10. The protruding component 201 also includes a first involute segment 2011, a second involute segment 2012, and a straight segment 2013. The straight segment 2013 is located between the first involute segment 2011 and the second involute segment 2012. The included angle between the first involute segment 2011 and the straight segment 2013 is an obtuse angle, and the included angle between the second involute segment 2012 and the straight segment 2013 is an acute angle. In this way, the screen body 10 and the protruding component 20 cooperate. The rotation of the screen body 10 can drive the protruding component 20 to rotate. The protruding component 20 can throw the material upward to reduce the adhesion of the material, prevent the protruding component 20 from sticking to the material, and improve the anti-clogging performance. It can also effectively crush the material or peel off the sticky material, preventing the material from directly entering the gap between two adjacent protruding components 201. It can loosen the material layer, destroy the structure of the material layer, separate large pieces of material from small pieces of material, clear the blockage layer, and reduce the amount of manual cleaning work. In addition, the protruding component 20 can also assist other equipment in completing the mud cleaning operation, ensuring the smooth operation of the equipment.

[0071] This application also provides a roller screen, which includes a screen shaft and the roller screen plate 1 described above.

[0072] According to the roller screen of this application, the roller screen includes a screen shaft and the aforementioned roller screen plates 1. Ten roller screen plates 1 are arranged along the axial direction of the screen shaft. In this way, the screen plate body 10 and the protruding component 20 cooperate. The rotation of the screen plate body 10 can drive the protruding component 20 to rotate. The protruding component 20 can throw the material upward to reduce the adhesion of the material, avoid the protruding component 20 from sticking together with the material, and improve the anti-clogging performance. It can also effectively crush the material or peel off the sticky material, preventing the material from directly entering the gap between two adjacent protruding components 201. It can loosen the material layer, destroy the structure of the material layer, separate large pieces of material from small pieces of material, play a good role in loosening the blockage, clear the blockage layer, and reduce the amount of manual cleaning work. In addition, the protruding component 20 can also assist other equipment in completing the mud cleaning operation, ensuring the smooth operation of the equipment.

[0073] Multiple roller screen plates 1 are arranged on the same screen shaft, and the multiple roller screen plates 1 are spaced apart along the axial direction of the screen shaft. The multiple roller screen plates 1 are sleeved on the outside of the same screen shaft. The multiple roller screen plates 1 are arranged coaxially with the same screen shaft so that the same screen shaft can pass through the multiple roller screen plates 1. The multiple roller screen plates 1 are arranged coaxially to form a screen plate group. Preferably, the multiple roller screen plates 1 have identical structures. The multiple roller screen plates 1 are equidistantly arranged along the axial direction of the screen shaft. For example, Figure 5 As shown, 10 roller screen plates 1 are arranged on a screen shaft. The 10 roller screen plates 1 are spaced apart along the axial direction of the screen shaft. The 10 roller screen plates 1 are equidistant from each other. The 10 roller screen plates 1 are arranged at equal intervals along the axial direction of the screen shaft.

[0074] The rotation of a single screen shaft enables multiple roller screen plates 1 on the same shaft to rotate synchronously. These multiple roller screen plates 1 rotate synchronously around the axial direction of the same screen shaft. The direction and speed of rotation of the multiple roller screen plates 1 are the same. This increases the effective contact area between the multiple roller screen plates 1 and the material, allowing the material to fully contact the multiple roller screen plates 1 during flow, reducing local accumulation, improving the uniformity of material screening, and enhancing the overall anti-clogging performance. It also improves the accuracy of material particle size control, reduces the wear rate and structural stress of individual roller screen plates 1, and reduces the risk of deformation or breakage. Furthermore, by adjusting the spacing between the multiple roller screen plates 1, the particle size of the screened material can be adjusted, improving the versatility of the equipment.

[0075] The roller screen has multiple screen shafts, which are spaced apart and arranged in parallel. The axial directions of the screen shafts are parallel to each other. Preferably, adjacent screen shafts are identical in construction and are spaced equidistant from each other. This allows the multiple screen shafts to rotate synchronously. The screen shafts rotate at the same speed. All screen shafts can rotate clockwise, or counterclockwise.

[0076] Adjacent screen shafts are arranged in a top-to-top configuration. Each screen shaft corresponds to one set of screen plates. Each screen shaft is equipped with one set of screen plates. Each screen shaft is spaced apart from its adjacent counterpart, allowing the sets of screen plates to be staggered. When one set of screen plates on one screen shaft is performing screening, another set of screen plates on another screen shaft can clear blockages between the multiple roller screen plates 1 within that set. In this way, the roller screen plates 1 can also be used to clean adjacent screen shafts of the same roller screen, preventing large pieces of material from entering the area below the roller screen through the gaps between two roller screen plates 1 on adjacent screen shafts. This improves anti-clogging performance, ensures screening accuracy, and also assists other equipment in cleaning operations, ensuring smooth operation of the equipment.
