Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: See Figures 1 to 5 A novel horizontal sand mill comprises: a base 1 and a barrel 14. A workbench 11 is installed on the upper end of the base 1.

A rotor 17 and a rotor 2 18 are also installed on the sand mill rotating shaft 12. A plurality of through holes 181 are distributed on the rotor 2 18. Both the rotor 17 and the rotor 2 18 extend into the barrel 14. A moving mechanism 2 is installed on the base 1 for adjusting the position of the barrel 14. A cooling mechanism 3 is installed on the barrel 14 for cooling the barrel 14. An auxiliary supporting mechanism 4 is installed in the barrel 14 for supporting the end of the rotor 2 18. In this embodiment, a feed pipe 15 is also installed on the right side of the barrel 14, the sand mill rotating shaft 12 is a hollow rotating shaft, a rotary joint 16 is installed on the left side of the sand mill rotating shaft 12, a filter head 19 is fixed to the right end of the sand mill rotating shaft 12, and a driving motor for driving the sand mill rotating shaft 12 to rotate is also installed on the workbench 11, and the rotary joint 16 is connected to an external negative pressure device, so as to facilitate the suction of the ground raw materials in the barrel 14.

[0023] The working principle of the utility model is as follows: during specific use, the barrel 14 is first installed on the moving mechanism 2, and then the moving mechanism 2 drives the barrel 14 to move left, so that the barrel 14 fits with the barrel cover 13. At this time, the auxiliary support mechanism 4 is inserted into the end of the rotor 18 to support the rotor 18 to avoid one end of the rotor being suspended in the air, thereby improving its working stability. Then the barrel cover 13 is fixed to the barrel, and then the feed pipe 15 is connected to the external silo, and air is pumped through the negative pressure device to generate negative pressure in the barrel 14, so that the raw materials to be processed are sucked into the barrel 14. Then, the sand mill rotating shaft 12 is driven by the driving motor to rotate, so that the rotor 17 and the rotor 2 18 are rotated, thereby moving the grinding medium in the barrel 14, and sand milling can be performed. At this time, the barrel can be cooled by the cooling mechanism 3.

[0024] As a further solution, the moving mechanism 2 includes a moving bracket 25 slidably mounted on the base 1, and a pair of moving seats 21 are also installed on the base 1. A moving screw 22 is rotatably mounted between the moving seats 21, and a moving slide 24 is threadedly mounted on the moving screw 22. The upper end of the moving slide 24 is fixedly connected to the lower end of the moving bracket 25. A moving motor 23 is also installed on the moving seat 21, and the output end of the moving motor 23 is drivingly connected to the shaft end of the moving screw 22. In this embodiment, the barrel 14 is fixed on the moving bracket 25.

[0025] The working principle of the moving mechanism 2 is: when moving, start the moving motor 23, and the moving motor 23 drives the moving screw 22 to rotate, thereby driving the moving slide 24 to move, and then the moving slide 24 drives the moving bracket 25 to move, thereby realizing the movement of the barrel 14. The barrel 14 can be moved left and right by the forward and reverse rotation of the moving motor 23. The operation is simple, and it is convenient for the installation and disassembly of the barrel, so as to facilitate the maintenance and cleaning of the rotor, which can better meet the use requirements.

[0026] As a further solution, the cooling mechanism 3 includes a cooling chamber 33 opened in the barrel 14, a water inlet pipe 31 and a water outlet pipe 32 are also installed on the barrel 14, and a spiral liquid guide strip 34 is also installed in the cooling chamber 33. The cooling chamber 33 can be divided into a spiral liquid infusion channel by providing the spiral liquid guide strip 34. In this embodiment, the water inlet pipe 31 is connected to an external water pump, and the water outlet pipe 32 is connected to an external water collection tank.

[0027] The working principle of the cooling mechanism 3 is: water is delivered to the cooling chamber 33 through an external water pump, and then the heat generated by sand grinding is absorbed, and then discharged through the water outlet pipe 32, so that the barrel 14 can be cooled.

[0028] As a further solution, the auxiliary support mechanism 4 includes an auxiliary turntable 41 rotatably installed in the barrel 14, and an auxiliary support ring 43 is fixed to the auxiliary turntable 41 through an auxiliary connecting seat 42. The end of the auxiliary support ring 43 is inserted into the right side port of the rotor 2 18. In order to facilitate the insertion of the auxiliary support ring 43, a chamfer 44 is provided on the end of the auxiliary support ring 43.

[0029] The working principle of the auxiliary support mechanism 4 is: the right end of the rotor 2 18 is supported by the auxiliary support ring 43, which can effectively prevent the right end of the rotor 2 18 from being in a suspended state, and can improve the working stability of the rotor 2 18, so as to better meet the use requirements.
