[0027] Please see Figures 1-5 This invention provides a bentonite processing sand removal device, including a base 101, a support shell 102, and a feeding structure 103. The support shell 102 is connected to the base 101 and located on top of the base 101. The feeding structure 103 is disposed on top of the support shell 102. The device also includes a multi-layer screen 104, a winding belt 105, a winder 106, a sliding baffle 108, and a collection box 109. The multi-layer screen 104 is slidably disposed within the support shell 102. The sliding baffle 108 is slidably disposed on one side of the multi-layer screen 104. The winder 106 is fixed to one side of the support shell 102. One end of the winding belt 105 is connected to the winder 106, and the other end of the winding belt 105 is connected to the sliding baffle 108. A feeding port is provided on the sliding baffle 108, and the collection box 109 is fixed to one side of the feeding port.

[0028] In this embodiment, the base 101 serves as the foundation of the entire device, providing stable support and ensuring good stability during operation. The support shell 102 is fixedly connected to the top of the base 101, housing and protecting the internal working components and providing a good supporting frame for the overall structure. The feeding structure 103 is located on the top of the support shell 102, used to evenly feed the bentonite raw material to be processed into the device for screening and sand removal.

[0029] The device incorporates a multi-layered screen 104, which is slidably installed inside the support shell 102. This screen allows for grading and screening of materials based on their different particle sizes. The multi-layered screen 104 design not only improves screening efficiency but also effectively removes impurities of varying sizes, particularly hard particles such as sand and gravel, thus ensuring the purity of the bentonite product.

[0030] In addition, the device includes a sliding baffle 108, which can slide and adjust its position along one side of the screen. After a period of operation, large-sized impurity particles may remain on the screen, so it can be moved to one side of the screen from below. The sliding baffle 108 is provided with a feed inlet, which can guide the impurities remaining on the screen into the collection box 109 for storage. After collecting from one screen, it can continue to move upward to process the impurities on the next screen, making the processing of impurities more convenient. Specifically, the winding device 106 provides upward pulling power to drive the winding belt 105 and the sliding baffle 108 to move.

[0031] Collection box 109 is used to receive bentonite products after screening and sand removal, and to collect them for subsequent transportation or further processing. Collection box 109 can be designed as a detachable structure for easy cleaning and replacement, depending on actual needs.

[0032] In summary, the bentonite processing sand removal device provided by the present invention has the advantages of compact structure, simple operation, high screening efficiency, and good impurity removal effect, and is suitable for the field of bentonite production and processing.

[0033] The multi-layer screen 104 includes multiple screen bodies 110, a support plate 111, and a vibrator 112. The support plate 111 is slidably disposed in the support shell 102. The multiple screen bodies 110 are fixed on the support plate 111. The aperture of the screen decreases sequentially from top to bottom. The vibrator 112 is disposed on one side of the support plate 111.

[0034] The support plate 111 is slidably disposed inside the support shell 102, serving as the load-bearing structure for the screen body 110. It can be moved and adjusted to a certain extent to facilitate the replacement, cleaning, or maintenance of the entire screen. Multiple screen bodies 110 are arranged sequentially from top to bottom according to their aperture size and fixed on the support plate 111, with the aperture size of each layer of screen decreasing progressively. This stepped screening structure design allows the material to be screened layer by layer downwards under its own weight and vibration. Larger particles of impurities are intercepted by the upper screen, while smaller particles are further separated by the lower screen, ultimately achieving the purpose of grading by particle size and effectively removing hard impurities such as sand and gravel.

[0035] To enhance screening efficiency, the vibrator 112 is installed on one side of the support plate 111, providing stable vibration power to the entire screen system. This promotes the uniform distribution of bentonite material on the screen and accelerates its passage through the screen holes, preventing material blockage and improving screening efficiency and continuous operation capability. The vibration frequency and amplitude of the vibrator 112 can be adjusted according to actual processing requirements to adapt to bentonite raw materials with different properties.

[0036] The multi-layer screen 104 also includes a side sealing strip 113, which is disposed between the support plate 111 and the support shell 102.

[0037] To prevent dust from escaping and material leakage during the screening process, the multi-layer screen 104 is specially equipped with a side sealing strip 113. This side sealing strip 113 is installed between the support plate 111 and the support shell 102, providing excellent sealing performance. It maintains a dynamic seal during the sliding of the support plate 111, ensuring both the stability and environmental friendliness of the equipment operation, while also preventing external impurities from entering the screening area and ensuring product quality.

[0038] The bentonite processing and sand removal device also includes a pressing structure, which is used to press the roll 105 onto the support shell 102 to improve the sealing effect.

[0039] The clamping structure includes a pressure plate 114, a clamping cylinder 115, multiple balls 116, and multiple support springs 117. The pressure plate 114 is slidably disposed on one side of the winding belt 105. The output end of the clamping cylinder 115 is connected to the pressure plate 114. The multiple balls 116 are slidably disposed on one side of the pressure plate 114. The support springs are disposed between the balls 116 and the pressure plate 114.

[0040] The pressure plate 114 is slidably disposed on one side of the roll 105 and contacts and engages with the surface of the roll 105. Its main function is to apply pressure through external power so that the roll 105 can be tightly attached to the surface of the support shell 102 to achieve a good sealing effect.

[0041] The clamping cylinder 115 serves as a driving component, with its output end fixedly connected to the pressure plate 114, and is used to control the extension and retraction of the pressure plate 114. When the equipment is started, the clamping cylinder 115 pushes the pressure plate 114 towards the winding belt 105, so that the pressure plate 114 applies a certain pressure to the winding belt 105; while during equipment maintenance or replacement of the winding belt 105, the clamping cylinder 115 can drive the pressure plate 114 to retract, making it easier for operators to perform related operations.

[0042] To reduce the frictional resistance between the pressure plate 114 and the winding belt 105 and to improve the uniformity and stability of the pressing process, a plurality of ball bearings 116 are provided on one side of the pressure plate 114. These ball bearings 116 can roll along the surface of the winding belt 105 during the movement of the pressure plate 114, which not only reduces frictional loss, but also ensures that the pressure plate 114 is subjected to more uniform force throughout the entire pressing stroke, thereby avoiding damage or deformation of the winding belt 105 due to excessive local pressure.

[0043] Multiple support springs 117 are also provided between the ball bearing 116 and the pressure plate 114. These support springs serve as buffers and adaptive adjusters. When the clamping cylinder 115 pushes the pressure plate 114 to apply pressure, the support springs are compressed, which can automatically adjust the pressure distribution between the different thicknesses or slightly uneven surfaces of the roll 105, ensuring a consistent overall clamping effect and also helping to protect the roll 105 from damage.

[0044] The sliding baffle 108 includes a baffle body 118, a receiving plate 119, and an elastic element 120. The receiving plate 119 has a triangular inclined surface 121 and is slidably disposed on the baffle body 118. The elastic element 120 is disposed between the baffle body 118 and the receiving plate 119. A protrusion 122 is provided below the screen. When the baffle body 118 moves upward, the protrusion 122 is used to contact the triangular inclined surface 121 to push the receiving plate 119 to move.

[0045] The belt 105 is connected to the rewinder 106, and can move up and down with the operation of the rewinder 106, thereby adjusting the opening and closing state of the feed inlet and the flow of materials. The receiving plate 119 is set on the baffle body 118 and has a triangular inclined surface structure. The triangular inclined surface 121 is set towards the screen, which facilitates contact and cooperation with the protrusion 122 set below the screen. The receiving plate 119 can slide along the surface of the baffle body 118. Its main function is to automatically extend or retract under specific working conditions to adjust the effective area of ​​the feed inlet, thereby controlling the material flow and screening efficiency.

[0046] An elastic element 120, typically a spring or other elastic material with restoring capability, is provided between the baffle body 118 and the receiving plate 119. The function of the elastic element 120 is to provide a certain initial preload to the receiving plate 119, keeping it in its original position when no external force is applied. When subjected to an external force (such as being pushed by the protrusion 122 below the screen), the receiving plate 119 can overcome the resistance of the elastic element 120 and move out of position. After the external force disappears, it automatically returns to its original position by the restoring action of the elastic element 120.

[0047] Specifically, when the sliding baffle 108 moves upward as a whole, the protrusion 122 below the screen contacts the triangular inclined surface 121 on the receiving plate 119 and slides upward along the inclined surface, generating a horizontal pushing force, thereby pushing the receiving plate 119 outward. This action can expand the opening area of ​​the feed inlet, which is beneficial to increasing the material throughput speed. When the baffle body 118 moves downward, the protrusion 122 disengages from the triangular inclined surface 121, and the receiving plate 119 automatically retracts under the action of the elastic element 120, reducing the feed inlet size and achieving precise control of the material flow rate.

[0048] The sliding baffle 108 also includes a counterweight 123, which is fixed below the baffle body 118.

[0049] To enhance the stability and inertia adjustment capability of the sliding baffle 108 during operation, the sliding baffle 108 further includes a counterweight 123, which is fixedly disposed below the baffle body 118. The counterweight 123 helps to balance the weight distribution of the baffle body 118 during its up-and-down sliding process, preventing swaying or displacement caused by vibration or external force. It also improves the self-stability of the sliding baffle 108 in its non-working state, ensuring that it can reliably be positioned at a certain location when operation stops, avoiding malfunctions that could affect the screening effect.

[0050] The collection box 109 includes a box body 124 and a discharge plate 125, the discharge plate 125 being rotatably disposed on one side of the box body 124.

[0051] The housing 124 is fixed to the inlet side of the sliding baffle 108 to receive the bentonite finished material falling from the screen system and to store it centrally for subsequent transfer or further processing. The discharge plate 125 is rotatably mounted on one side of the housing 124 and can be opened or closed as needed to achieve controlled discharge of materials.

[0052] The bentonite processing sand removal device also includes a temporary storage box 126, a crushing structure 127, a second cylinder 128, and a cover plate 129. The temporary storage box 126 is rotatably disposed inside the support shell 102. The second cylinder 128 is fixed above the temporary storage box 126. The cover plate 129 is connected to the output end of the second cylinder 128. The crushing structure 127 is disposed below the cover plate 129.

[0053] The temporary storage box 126 is rotatably mounted inside the support shell 102, serving as a temporary storage area for bentonite raw materials before entering the screening process. It can rotate around a fixed axis, switching its position (such as tilted or vertical) under different operating conditions, thereby controlling the material flow direction. After the crushing operation is completed, the temporary storage box 126 can be flipped to evenly guide the material onto the multi-layer screen 104, ensuring the continuity and stability of the screening process.

[0054] The second cylinder 128 is fixedly installed above the temporary storage box 126, and its output end is connected to the cover plate 129. The cover plate 129 is located at the top opening of the temporary storage box 126 and can move up and down driven by the second cylinder 128 to open or close the upper entrance of the temporary storage box 126. When the cover plate 129 is pressed down, a sealed space is formed to prevent dust from escaping during the crushing process; at the same time, it provides a stable working environment for the crushing structure 127.

[0055] The crushing structure 127 is located below the cover plate 129 and specifically includes a crushing roller, a motor, and a transmission mechanism. It is used to perform preliminary crushing of large or agglomerated bentonite raw materials to make their particle size more uniform, which is beneficial for subsequent screening and sand removal operations. The crushing structure 127 can be set with different crushing particle sizes according to actual needs, so that the collected impurities can be crushed again and screened to improve the utilization rate of raw materials.

[0056] The bentonite processing sand removal device also includes a rack 130, a gear 131, and a damping block 132. The rack 130 is fixedly connected to the cover plate 129 and is located on one side of the cover plate 129. The gear 131 is fixedly connected to the temporary storage box 126. The damping block 132 is disposed between the gear 131 and the support shell 102. When the cover plate 129 moves down to the designated position, the rack 130 and the gear 131 mesh to drive the temporary storage box 126 back to the vertical state.

[0057] The rack 130 is fixedly connected to one side of the cover plate 129 and moves synchronously with the cover plate 129. The gear 131 is fixedly connected to the temporary storage box 126 and is usually located near the rotating shaft, enabling the temporary storage box 126 to rotate around the shaft. The damping block 132 is located between the gear 131 and the support shell 102, serving as a buffer and limiting element to ensure smooth operation of the temporary storage box 126 during rotation and prevent structural damage due to inertial impact. When the cover plate 129 moves downward to the designated position under the drive of the second cylinder 128, the rack 130 meshes with the gear 131, driving the temporary storage box 126 to rotate a certain angle through the gear 131, automatically returning it from an inclined state to a vertical state. This design not only improves the automation level of the equipment but also reduces the need for manual intervention, enhancing overall work efficiency and operational safety.

[0058] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
