Description

Technical Field

[0001] This application relates to the field of sand mills, and more particularly to a high-flow sand mill. Background Technology

[0002] The sand mill is the most adaptable, advanced, and efficient grinding equipment for materials. It has the narrowest grinding chamber, the smallest lever gap, and the most concentrated grinding energy. Combined with a high-performance cooling system and an automatic control system, it can realize continuous material processing and continuous discharge, which greatly improves production efficiency.

[0003] Traditional sand mills are limited by their structure and usually have a small flow rate, making them unsuitable for the production of some products with large batches. In actual use, high-flow sand mills on the market will cause the transmission belt in the belt drive mechanism to become loose due to the increased load on the transmission mechanism. The tensioning mechanism in the existing belt drive mechanism needs to be manually adjusted. Once the loose transmission belt is not detected in time, it will directly lead to increased wear between the transmission belt and the pulley, thus directly affecting the normal operation of the sand mill. Utility Model Content

[0004] To address the issue that severe wear of the transmission mechanism in existing high-flow sand mills significantly affects their working efficiency, this application provides a high-flow sand mill.

[0005] This application provides a high-flow sand mill with the following technical solution:

[0006] A high-flow sand mill includes a base, a housing mounted on the base, and a transmission box mounted on one side of the housing. A motor is fixedly connected to the top outer wall of the housing, and a grinding cylinder is installed on the top outer wall of the base. A driving pulley and a driven pulley are rotatably connected to the inner wall of one side of the transmission box. A tensioning assembly is provided on the inner wall of the transmission box. The driving pulley and the driven pulley are connected by the same belt, and the tensioning assembly is in contact with the belt.

[0007] By adopting the above technical solution, the cooperation between the chassis, transmission box, and motor facilitates the direct drive of the grinding roller in the grinding cylinder to rotate, thereby facilitating the grinding of the raw materials in the grinding cylinder. The cooperation between the drive pulley and the driven pulley in the transmission box facilitates the installation of the belt, and the setting of the tensioning component facilitates the adjustment of the belt tension.

[0008] The tensioning assembly includes a mounting plate rotatably connected to the inner wall of the transmission box, and a rectangular groove is provided on one outer wall of the mounting plate, with a bearing seat slidably connected to the inner wall of the rectangular groove.

[0009] By adopting the above technical solution, the mounting plate is rotated and installed on the inner wall of the transmission box, and the rectangular groove facilitates the sliding installation of the bearing seat.

[0010] A tension pulley is rotatably connected to one side of the outer wall of the bearing housing, and the tension pulley is in contact with the belt.

[0011] By adopting the above technical solution, the installation of the tension pulley is convenient through the setting of the bearing housing. When the tension pulley presses the belt, it effectively reduces the occurrence of belt slippage.

[0012] A pressure sensor is fixedly connected to one inner wall of the rectangular groove, and the same spring is fixedly connected between the pressure sensor and the bearing seat. An electric telescopic rod is rotatably connected to one outer wall of the mounting plate, and one end of the electric telescopic rod is rotatably connected to the inner wall of the transmission box.

[0013] By adopting the above technical solution, the belt drives the tension pulley to move, which in turn drives the bearing housing to compress the spring. When the spring is compressed, it will squeeze the pressure sensor, thus facilitating the detection of the belt tension through the pressure sensor.

[0014] The output shaft of the motor is fixedly connected to the drive pulley, and a transmission shaft connected to the driven pulley is rotatably installed in the housing, and the transmission shaft is connected to the grinding cylinder.

[0015] By adopting the above technical solution, the motor directly drives the active pulley to rotate, and when the active pulley rotates, it works in conjunction with the belt to drive the driven pulley to rotate.

[0016] A sliding groove is provided on one side of the outer wall of the base, and a guide rail is slidably connected to the inner wall of the sliding groove.

[0017] By adopting the above technical solution, the end cap of the grinding cylinder can be easily disassembled and assembled using the sliding guide rail frame.

[0018] One end of the grinding cylinder is fixedly connected to a discharge pipe, and a thermometer is fixedly connected to the outer wall of the discharge pipe. Cooling water outlet pipe and cooling water inlet pipe are fixedly connected to the outer wall of the grinding cylinder respectively.

[0019] By adopting the above technical solution, the discharge pipe facilitates the direct discharge of the ground raw material, the thermometer facilitates real-time monitoring of the discharge temperature, and the two water outlet pipes facilitate cooling of the grinding cylinder.

[0020] A feed pump is fixedly connected to one side of the outer wall of the base, and a damping tank is installed on the grinding cylinder, with the damping tank and the feed pump connected in communication.

[0021] By adopting the above technical solution, the raw materials can be conveniently transported directly into the grinding cylinder through the cooperation between the feed pump and the damping tank.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application provides a tensioning assembly in the transmission box. The tensioning assembly facilitates the tension adjustment of the transmission belt. The cooperation between the pressure sensor mounted on the mounting plate of the tensioning assembly and the bearing seat facilitates the detection of the tension force of the tensioning pulley on the belt, thereby enabling real-time monitoring of the belt tension.

[0024] 2. This application incorporates an electric telescopic rod in the tensioning assembly. The electric telescopic rod allows for direct rotation of the mounting plate, facilitating adjustment of the position of the tensioning pulley and thus adjusting the belt tension. This reduces slippage between the belt and the pulley, thereby improving the belt transmission efficiency. Attached Figure Description

[0030] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0031] This application discloses a high-flow sand mill.

[0032] Reference Figure 1-3A high-flow sand mill includes a base 1, a casing 2 mounted on the base 1, and a transmission box 3 mounted on one side of the casing 2. A motor 4 is fixedly connected to the top outer wall of the casing 2. A grinding cylinder 5 is mounted on the top outer wall of the base 1. A sliding groove is opened on one side outer wall of the base 1, and a guide rail frame 8 is slidably connected to the inner wall of the sliding groove. A discharge pipe 10 is fixedly connected to one end of the grinding cylinder 5, and a thermometer 11 is fixedly connected to the outer wall of the discharge pipe 10. A cooling water outlet pipe 6 and a cooling water inlet pipe 7 are fixedly connected to the outer wall of the grinding cylinder 5 respectively. A feed pump 15 is fixedly connected to one side outer wall of the base 1. A damping tank 16 is mounted on the grinding cylinder 5, and the damping tank 16 is connected to the feed pump 15.

[0033] In use, the feed pump 15 and the damping tank 16 work together to easily deliver the raw materials directly into the grinding cylinder 5. The discharge pipe 10 facilitates the direct discharge of the raw materials after grinding. The temperature gauge 11 facilitates real-time monitoring of the discharge temperature. The two water outlet pipes facilitate cooling of the grinding cylinder 5. The sliding guide rail 8 facilitates the disassembly and assembly of the end caps of the grinding cylinder 5.

[0034] Reference Figure 2-3 The inner wall of the transmission box 3, which assists in the power transmission of the sand mill, is rotatably connected to a drive pulley 12 and a driven pulley 13. A tensioning assembly 17 is provided on the inner wall of the transmission box 3. The same belt 14 connects the drive pulley 12 and the driven pulley 13. The tensioning assembly 17 and the belt 14 are in contact. The output shaft of the motor 4 is fixedly connected to the drive pulley 12. A transmission shaft connected to the driven pulley 13 is rotatably installed in the housing 2. The transmission shaft is connected to the grinding cylinder 5. The motor 4 directly drives the drive pulley 12 to rotate. When the drive pulley 12 rotates, it works with the belt 14 to drive the driven pulley 13 to rotate.

[0035] Reference Figure 3-4 The tensioning assembly 17 includes a mounting plate 18 rotatably connected to the inner wall of the transmission box 3, and a rectangular groove 21 is provided on one outer wall of the mounting plate 18. A bearing seat 22 is slidably connected to the inner wall of the rectangular groove 21. A tensioning pulley 20 is rotatably connected to one outer wall of the bearing seat 22, and the tensioning pulley 20 is in contact with the belt 14. A pressure sensor 23 is fixedly connected to one inner wall of the rectangular groove 21, and the same spring 24 is fixedly connected between the pressure sensor 23 and the bearing seat 22. An electric telescopic rod 19 is rotatably connected to one outer wall of the mounting plate 18, and one end of the electric telescopic rod 19 is rotatably connected to the inner wall of the transmission box 3.

[0036] In use, the belt 14 drives the tension pulley 20 to move, which in turn drives the bearing seat 22 to compress the spring 24. When the spring 24 is compressed, it will squeeze the pressure sensor 23, so that the tension of the belt 14 can be detected by the pressure sensor 23. The electric telescopic rod 19 drives the mounting plate 18 to rotate, thereby adjusting the tension.

[0037] The implementation principle of a high-flow sand mill according to an embodiment of this application is as follows: In use, the raw material to be ground is transported to the grinding cylinder 5 through the feed pump 15. Then, the motor 4 is started, and through the cooperation between the belt 14 and the pulley, it can directly drive the transmission shaft to grind the raw material in conjunction with the grinding cylinder 5. When the tension pulley 20 and the belt 14 are in contact, the force of the belt 14 directly drives the bearing seat 22 to compress the spring 24. When the spring 24 is compressed, the tension force of the tension pulley 20 is detected in real time by the pressure sensor 23. When the tension force is too large or too small, the position of the tension pulley 20 needs to be adjusted directly. During adjustment, the electric telescopic rod 19 is started, which directly drives the mounting plate 18 to move. When the mounting plate 18 moves, it is convenient to directly adjust the position of the tension pulley 20.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
