Description

Technical Field

[0001] The utility model relates to the field of sand mills, in particular to a turbine rod pin nano sand mill with automatic bead addition. Background Technique

[0002] A sand mill is a professional device for grinding materials. After the materials are 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 coarse-grained materials from one end and discharges the ground fine materials from the other end. Since the steel beads in the grinding barrel need to be replenished after being worn out in order to better grind the materials in cooperation with the grinding turbine, and most sand mills on the market add steel beads to the grinding barrel by the traditional method of leaking steel beads through a funnel. After the steel beads are added to the grinding barrel, they will accumulate near the through hole for adding steel beads in the grinding barrel, which easily causes the accumulation of steel beads, making it impossible to continue adding steel beads, resulting in problems such as unsmooth bead addition, low bead addition efficiency, time-consuming and laborious bead addition. Summary of the Invention

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a turbine rod pin nano sand mill with automatic bead addition.

[0004] To solve the above technical problems, the utility model adopts the following technical solution: The turbine rod pin nano sand mill with automatic bead addition includes a machine table. A grinding barrel is provided on the left part of the machine table, and a frame is provided on the right part of the machine table. A side cover is provided on one side of the grinding barrel, and a bearing seat is provided on the other side of the grinding barrel. The grinding barrel is connected and installed to the frame through the bearing seat; The grinding barrel includes a cooling outer barrel, a grinding inner barrel is provided inside the cooling outer barrel, an automatic bead addition hopper is provided on the grinding inner barrel, an electric check valve is provided at the lower end of the automatic bead addition hopper, the automatic bead addition hopper is externally connected to an air storage tank through a hose, a first pressure gauge for displaying the air pressure in the automatic bead addition hopper is provided on the automatic bead addition hopper, a pressure regulating valve for adjusting the size of the deflation air pressure is installed on the hose, a pressure gauge for displaying the air pressure is provided on the air storage tank, and the air storage tank inflates the automatic bead addition hopper through the hose. The automatic bead addition hopper refers to a funnel for automatically adding steel beads.

[0005] By adopting the above technical solution, the pressure regulating valve can adjust the size of the deflation air pressure, increasing the air pressure in the automatic bead addition hopper and forcing the steel beads inside it to enter the grinding inner barrel through the electric check valve, so as to realize the automatic addition of steel beads to the grinding inner barrel. It has the advantages of smooth bead addition, high bead addition efficiency, time-saving and labor-saving bead addition, and avoids the phenomenon that when adding steel beads to the grinding inner barrel by the traditional method of leaking steel beads through a funnel, the steel beads are likely to accumulate near the through hole for adding steel beads in the grinding inner barrel, resulting in unsmooth bead addition or inability to continue adding steel beads due to the accumulation of steel beads.

[0006] Preferably, a discharge port is provided on the side cover, and a discharge screen is installed in the discharge port.

[0007] By adopting the above technical solution, the discharge screen can filter the materials whose particles do not meet the fineness requirements after grinding, while the materials whose particles meet the fineness requirements can pass through the discharge screen and be discharged from the grinding inner barrel.

Similarly, when the grinding barrel is disassembled from the machine frame, the grinding barrel can linearly slide on the track of the machine table through the track wheels to adjust the distance of the grinding barrel away from the machine frame, which also avoids the trouble of manually lifting the grinding barrel. The combined design of the track wheels and the track can facilitate the staff to assemble the grinding barrel or remove the grinding barrel from the machine table, so as to reduce the working intensity of the assembly personnel and achieve time-saving and labor-saving.

The automatic bead adding hopper is externally connected to an air storage tank through a hose. A first pressure gauge for displaying the air pressure in the automatic bead adding hopper is provided on the automatic bead adding hopper. A pressure regulating valve is installed on the hose. An air pressure gauge for displaying the air pressure is provided on the air storage tank. The air storage tank inflates the automatic bead adding hopper through the hose.

It realizes automatic bead adding to the inner grinding barrel, and has the advantages of smooth bead adding, high bead adding efficiency, time-saving bead adding and labor-saving bead adding. It effectively solves the problem that most of the existing bead mills use the traditional method of leaking steel beads through a funnel to add steel beads to the grinding barrel, which will cause the steel beads to accumulate near the through hole for adding steel beads to the grinding barrel after being added to the grinding barrel, easily resulting in bead accumulation and causing unsmooth bead adding or being unable to continue adding beads due to the blockage of the accumulated steel beads.

[0021] 2. It is equipped with a discharge pipe and an ultrasonic vibrator on the side sealing plates on the sides of the discharge opening respectively.
