Description

Technical Field

[0001] The utility model relates to the field of sand mills, in particular to an ultrasonic cleaning screen turbine pin nano sand mill. Background Art

[0002] A sand mill is a professional device for grinding materials. After being ground by the sand mill, the coarse-grained materials can be ground into fine-grained materials that meet the standards. The grinding barrel of a conventional sand mill feeds the coarse-grained materials from one end and then discharges the ground fine materials from the other end. Currently, most sand mills on the market are generally provided with a discharge screen at the discharge end. During the grinding process of the sand mill, the materials will be mixed with particles of different sizes. The fine-grained materials are easily discharged through the discharge screen, while the coarse-grained particles will get stuck on the discharge screen during the discharge process and accumulate at the discharge end of the grinding barrel, causing the discharge screen to be easily blocked, and ultimately resulting in the problems of unsmooth discharge or inability to discharge of the sand mill. And when the discharge screen at the discharge end of the grinding barrel is blocked, it needs to be manually disassembled and the materials stuck on the discharge screen need to be manually cleaned, which not only has the disadvantage of low discharge efficiency, but also leads to a large labor intensity of the workers. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide an ultrasonic cleaning screen turbine pin nano sand mill, the overall structural design of which can achieve discharging only after the grinding precision of the materials is controlled up to the standard, and can realize automatic blockage clearing, automatic cleaning and automatic waste water and waste residue discharging, so that it has the advantages of high discharging efficiency, good discharging effect and good grinding effect. It not only effectively solves the problem that the current sand mill structure is prone to blockage, resulting in unsmooth discharge or inability to discharge, but also solves the problem that when the discharge end of the current sand mill is blocked, manual participation is required to disassemble the discharge filter screen and clean the materials stuck on the discharge filter screen, resulting in a large labor intensity of the workers. The utility model is realized through the following technical solutions:

[0004] An ultrasonic cleaning screen turbine pin nano sand mill, comprising a machine table, a frame is arranged on the machine table, a water tank is arranged on one side of the machine table, and a grinding mechanism for grinding materials is also arranged on the machine table; a power mechanism for driving the grinding mechanism to perform grinding motion and feeding the grinding materials is arranged on the frame;

[0005] The grinding mechanism includes a grinding barrel. A main shaft is disposed through the center of the grinding barrel. A grinding turbine is installed on the main shaft. One end of the main shaft is connected to a power mechanism, and an outlet turbine is installed at the other end of the main shaft. An outlet port with an inclined surface is provided on the circumference of the outlet turbine. A bearing seat is provided on one side of the grinding barrel. The main shaft passes through the bearing seat. A side cover is installed on the other side of the grinding barrel.

It enables the particulate materials with sufficiently fine particle size to be discharged in a floating manner, thereby ensuring good grinding effect of the discharged materials.

The controller is a PLC programmable logic controller. The PLC programmable logic controller can adopt a programmable logic controller with the place of origin being Shenzhen and the model being XDS-40T-D, but it is not limited thereto.

[0023] Compared with the existing technology, the beneficial effects of the present utility model are as follows: 1. By designing the structure of the discharge turbine and respectively installing a discharge pipe, a cleaning pipe and an ultrasonic vibration rod on the side sealing plate, the ultrasonic vibration rod can use the high-frequency vibration of ultrasonic waves to remove the stuck objects on the discharge filter screen, enabling the discharge screen to automatically remove blockages, avoiding blockages, and thus ensuring smooth discharge and high discharge efficiency.

[0025] 3.

It enables the particulate materials with fine enough particle size to be discharged in a floating manner, that is, it can effectively control the grinding precision of the materials to meet the standard before discharging, ensuring that the particle size of the discharged materials is fine enough, and further ensuring good grinding effect of the discharged materials.

[0040] In one embodiment, an operation box 8 is provided on the front surface of the frame 23.

[0041] In one embodiment, the operating process and structural design principle of the ultrasonic cleaning sieve mesh turbine rod pin nano sand mill are as follows: Materials enter the grinding inner barrel 17 through the feed pipe 18. When the motor 21 of the power mechanism 2 starts, it can drive the main shaft 3 to rotate synchronously through the pulley assembly. When the main shaft 3 rotates, it can drive the grinding turbine 4 and the discharge turbine 5 to rotate synchronously. When the grinding turbine 4 rotates, it can evenly grind the materials entering the grinding inner barrel 17. As more and more materials enter the grinding inner barrel 17 through the feed pipe 18, during the grinding process of the grinding turbine 4 on the materials, the ground materials can be pushed towards the discharge turbine 5. By setting a discharge port 6 with an inclined surface on the circumference of the discharge turbine 5 and one or more diversion holes 14 on one side surface of the discharge turbine 5, the materials ground by the grinding turbine 4 can be conveyed into the discharge turbine 5 through the discharge port 6 and the diversion holes 14 of the discharge turbine 5.

A discharge pipe 11 and an ultrasonic vibration rod 12 are respectively installed on the side sealing plate 10, and the installation position of the discharge pipe 11 is set above the center position of the side sealing plate 10. The above structural design ensures that the particulate materials with qualified particle size can float into the discharge pipe 11 through the discharge filter screen 9, while the materials with coarser particle size can be dispersed until the particles are fine enough under the action of the centrifugal dispersion force of the discharge turbine 5 and then float into the discharge pipe 11. It enables the particulate materials with fine enough particle size to be discharged in a floating manner, thereby ensuring good grinding effect of the discharged materials. When the discharge filter screen 9 is blocked, it uses the high-frequency ultrasonic vibration of the ultrasonic vibration rod 12 to vibrate and remove the stuck materials on the discharge filter screen 9, so as to realize automatic blockage removal and prevent the discharge filter screen 9 from being blocked, ensuring that the discharge filter screen 9 can maintain smooth discharge and thus improving the discharge efficiency of the discharge filter screen 9.
