Description
Technical Field
[0001] This utility model relates to the technical field of quartz sand roller mills, specifically a hydraulic spring composite quartz sand roller mill. Background Technology
[0002] Double-roll crushers are widely applicable to the medium and fine crushing of various hard and brittle materials such as rocks, abrasives, refractory materials, cement clinker, and ores. The hydraulic system in the hydraulic spring composite quartz sand double-roll crusher uses hydraulic oil pressure to drive the piston movement of the hydraulic cylinder, enabling rapid and precise adjustment of the gap between the two rollers. Whether for coarse, medium, or fine crushing, when the equipment encounters excessively hard impurities mixed in the quartz sand, the hydraulic system automatically retracts to prevent damage from overload. The spring device ensures the stability of the equipment's operation. During normal operation, the springs provide appropriate preload, ensuring a stable gap between the two rollers and enhancing the continuity of crushing force. When encountering difficult-to-crush materials, the hydraulic system retracts while the springs compress simultaneously, acting as a buffer to absorb instantaneous impact energy and prevent severe vibration. After the abnormal situation is resolved, the springs quickly return to their original position, allowing the equipment to rapidly resume normal operation and ensuring the continuity of the production process.
[0003] Currently, when encountering materials that are too hard or too large, the hydraulic system will automatically retract, increasing the gap between the two rollers. While this allows hard impurities to fall through, unbroken materials will also fall through the gap, resulting in lower sand quality. Utility Model Content

This timely guides the uncrushed material to the filter plate for screening, preventing uncrushed material from being mixed into the finished product and ensuring the quality of the product particle size. This solves the problem that the hydraulic system automatically retracts, increasing the gap between the two rollers. Although this allows excessively hard impurities to fall through, uncrushed material will also fall through the gap, resulting in lower sand quality.

Detailed Implementation
[0020] 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.
[0021] Please see Figures 1-5 This utility model discloses a hydraulic spring composite quartz sand roller mill, including a roller mill body 1 and a hydraulic spring mechanism 2 connected to the moving roller of the roller mill body 1. It also includes: a discharge conveyor belt 17 set at the discharge port of the roller mill body 1, a filter plate 3 inclinedly set on the discharge conveyor belt 17, the filter plate 3 being inserted into the inside side of the roller mill body 1 through a through groove, the filter plate 3 being installed inside the roller mill body 1 by a fixing device, and a receiving box 4 being set at the bottom of the discharge end of the filter plate 3; a material guiding device set inside the roller mill body 1, one end of the material guiding device being set at the bottom of the two roller shafts of the roller mill body 1, and the other end of the material guiding device being connected to the discharge conveyor belt 17. When the moving roller of the roller mill body 1 moves, the material guiding device is adjusted to be connected to the filter plate 3.
[0022] Specifically, the material guiding device includes a material guiding plate 5, an electric push rod 6, and an infrared ranging sensor 7. The material guiding plate 5 is inclinedly arranged inside the roller body 1. One end of the material guiding plate 5 near the roller shaft of the roller body 1 is connected to the inner wall of the roller body 1 through a fixed shaft. A sealing component is provided on the surface of the material guiding plate 5. A connecting plate 8 is fixedly arranged inside the roller body 1. One end of the electric push rod 6 is hinged to the surface of the connecting plate 8 through a hinge shaft. The other end of the electric push rod 6 is hinged to the bottom of the material guiding plate 5 through a hinge shaft. The infrared ranging sensor 7 is fixedly arranged on the inner wall of the roller body 1. The output end of the infrared ranging sensor 7 faces the moving roller of the roller body 1.
[0023] In this implementation scheme, when the moving roller retracts due to encountering excessively hard or large materials, the uncrushed material also falls through the gap. Simultaneously, the infrared ranging sensor 7 of the roller body 1 detects the movement of the moving roller. Then, the controller controls the extension shaft of the electric push rod 6 to push the guide plate 5 to rotate around the fixed shaft, so that one end of the guide plate 5 contacts one end of the filter plate 3. Thus, the uncrushed material flows along the guide plate 5 onto the filter plate 3, where the filter plate 3 filters the uncrushed material. The uncrushed material then flows along the filter plate 3 into the receiving box 4, completing the screening. By setting up the guiding device, the uncrushed material can be specifically guided to the filter plate 3 for screening when encountering excessively hard or large materials, reducing the contact and friction between the filter plate 3 and the normally crushed material, thereby extending the service life of the filter plate 3 and avoiding excessive accumulation and blockage of material at the discharge port.
[0024] Specifically, the sealing assembly includes a guide frame 9, a sealing plate 10, a return spring 11, and a driving component. The guide frame 9 is disposed on the end surface of the guide plate 5 near the filter plate 3. The sealing plate 10 is slidably disposed inside the guide frame 9. One end of the return spring 11 is fixedly connected to the inner side wall of the guide frame 9, and the other end of the return spring 11 is fixedly connected to the top of the sealing plate 10. The driving component is used to drive the sealing plate 10 to open and close.
[0025] The driving component includes an electromagnet 18 and a magnetic block 12. The electromagnet 18 is fixedly installed on the top inner side of the guide frame 9, and the magnetic block 12 is fixedly installed on the top surface of the sealing plate 10. The electromagnet 18 and the magnetic block 12 are magnetically connected.
[0026] In this embodiment, when the electromagnet 18 is magnetically connected to the magnetic block 12, the reset spring 11 is in a compressed state. After the infrared ranging sensor 7 detects the movement of the moving roller, it controls the electromagnet 18 to be de-energized through the controller, so that the electromagnet 18 loses its magnetic force. Then, under the elastic reset of the reset spring 11, it drives the sealing plate 10 to move downward along the guide frame 9, so that the sealing plate 10 is closed, thereby sealing the unbroken material on the surface of the guide plate 5 onto the guide plate 5, preventing the unbroken material from falling off the guide plate 5 during the adjustment process. After the guide plate 5 is connected to the filter plate 3, the electromagnet 18 is energized to generate magnetism, and under the action of the magnetic block 12, the sealing plate 10 is opened, while the reset spring 11 is squeezed and elastically compressed, releasing the material on the guide plate 5.
[0027] Specifically, the surface of the guide plate 5 is inclined with multiple fixing plates 13, and each pair of fixing plates 13 are arranged crosswise.
[0028] In this embodiment, by setting a fixed plate 13, when the material is on the guide plate 5, it will flow along the surface of the fixed plate 13 in sequence, thereby increasing the stroke and preventing the material from falling off the guide plate 5 quickly during adjustment.
[0029] Specifically, the fixing device includes two plug sleeves 14 and a snap-fit component. The plug sleeves 14 are fixedly installed at the opening of the through groove of the roller body 1. The two plug sleeves 14 are respectively sleeved on both sides of the filter plate 3. The snap-fit component is installed on the surface of the plug sleeves 14 and is used to snap-fit and fix the filter plate 3.
[0030] The snap-fit component includes a hinge seat 15 and a cam clip 16. The hinge seat 15 is fixedly mounted on the surface of the plug sleeve 14. The cam portion of the cam clip 16 is hinged to the hinge seat 15. The cam portion of the cam clip 16 passes through the plug sleeve 14 and fits tightly against the filter plate 3.
[0031] In this embodiment, when the filter plate 3 needs to be disassembled and replaced, the cam part of the cam clip 16 is disengaged from the filter plate 3 by moving the cam clip 16, thereby releasing the limiting position on the filter plate 3. Then the filter plate 3 is pulled out from the insertion sleeve 14 for replacement. After that, the cam clip 16 is reversed so that the cam part of the cam clip 16 presses against the surface of the filter plate 3 and fits tightly against the filter plate 3, thereby locking and fixing the filter plate 3, so as to facilitate the replacement of the filter plate 3.
[0032] The working principle and usage process of this utility model are as follows: During use, quartz sand raw material is fed into the roller mill body 1 through the feed inlet. The raw material is crushed by the two rollers. The crushed material falls onto the surface of the guide plate 5, and then flows down the inclined surface of the guide plate 5 onto the surface of the discharge conveyor belt 17. The discharge is completed by the discharge conveyor belt 17. When encountering excessively hard or large materials, the hydraulic spring mechanism 2 causes the moving roller to retract, allowing the excessively hard or large materials to flow out. Uncrushed materials also fall through the gaps. Simultaneously, the infrared sensor of the roller mill body 1... The distance sensor 7 detects the movement of the moving roller, and then controls the extension shaft of the electric push rod 6 to extend through the controller, pushing the guide plate 5 to rotate around the fixed shaft. At the same time, the two ends of the electric push rod 6 rotate under the action of the hinge shaft, so that one end of the guide plate 5 contacts one end of the filter plate 3. Thus, the uncrushed material will flow along the guide plate 5 to the filter plate 3. The filter plate 3 will filter the uncrushed material, so that the standard particles fall through the mesh of the filter plate 3 onto the discharge conveyor belt 17. The uncrushed material will flow along the filter plate 3 into the receiving box 4, completing the screening.
