Description

Technical Field

[0001] The present invention relates to the technical field of wet grinding equipment, and more particularly to an ultrafine wet grinding equipment. Background Art

[0002] Grinding device is one of the essential equipment in the coating production process. It is used to grind raw materials and powders to the required fineness and particle size. Wet grinder is a kind of grinding device. Wet grinder is widely used in various powder processing industries such as non-metallic minerals, chemicals, medicine, metallurgy, etc.

[0003] However, in order to fully grind, the existing wet grinder usually has two grinding chambers, each equipped with two sets of grinding mechanism components, which not only occupies a large volume, but also has a complex mechanical structure and consumes more energy. At the same time, the grinding effect cannot be guaranteed and the grinding efficiency is low.

[0004] Therefore, providing an ultrafine wet grinding device with a simple structure and reliable grinding effect is an urgent problem to be solved by those skilled in the art. Summary of the invention

[0005] In view of this, the present invention provides an ultrafine wet grinding device, aiming to solve one of the above-mentioned technical problems in the prior art at least to a certain extent.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] An ultrafine wet grinding device comprises a frame, two bases, a grinding chamber, a motor, a rotating shaft, a plurality of V-shaped stirring rod groups, a plurality of baffles, a screen and two telescopic cylinders.

[0008] The frame forms an internal space;

[0009] The two bases are respectively installed at two ends of the bottom of the frame, and the two bases support the frame above the ground;

[0010] The grinding chamber is arranged in the internal space, a feed port is provided near the upper part of the grinding chamber, a discharge port is provided at the lower part of the grinding chamber, and the discharge port is communicated with the outside of the frame;

[0011] The motor is mounted on the top of the frame;

[0012] The rotating shaft is drivingly connected to the motor and driven to rotate by the motor, and the rotating shaft extends into the grinding chamber;

[0013] A plurality of V-shaped stirring rod groups are symmetrically installed on both sides of the rotating shaft along the extending direction of the rotating shaft;

[0014] A plurality of baffles are respectively installed on both sides of the inner wall of the grinding chamber, and the baffles correspond to the V-shaped stirring rod group;

[0015] The screen is arranged below the extending end of the rotating shaft, and the length of the screen is greater than the width of the grinding chamber;

[0016] The two telescopic cylinders are symmetrically mounted on both sides of the frame, and telescopic rods of the two telescopic cylinders extend into the grinding chamber and are fixedly connected to two ends of the screen respectively.

[0017] By adopting the above scheme, the beneficial effects of the present invention are:

[0018] The present invention has only one grinding chamber, which reduces the occupied area and simplifies the mechanical structure. With the cooperation of the V-shaped stirring rod group and the baffle, the grinding is sufficient. At the same time, the screen can block the ground material with substandard fineness from entering the discharge port. Under the stretching action of the telescopic cylinders on both sides, the ground material on the screen is lifted up again to between the V-shaped stirring rod group and the baffle for re-grinding until the grinding fineness reaches the standard and can pass through the screen into the discharge port, thereby ensuring the grinding effect and improving the grinding efficiency.

[0019] Furthermore, it also includes a heat dissipation fan, which is installed on a side of the rack.

[0020] The beneficial effect of adopting the above further technical solution is that the heat dissipation fan can disperse part of the heat generated in the grinding chamber to the outside of the frame, thereby achieving the purpose of cooling.

[0021] Furthermore, it also includes a solenoid valve, which is connected to the telescopic cylinder.

[0022] The beneficial effect of adopting the above further technical solution is that the solenoid valve is used to switch and control the opening and closing of the air circuit, and control the compressed air to act on the telescopic cylinder, so as to adjust the speed of its extension and retraction.

[0023] Furthermore, it also includes a funnel, which is installed on the discharge port.

[0024] The beneficial effect of adopting the above further technical solution is that the design of the funnel facilitates the centralized collection and processing of the ground materials.

[0025] Furthermore, the V-shaped stirring rod group includes an upper stirring rod and a lower stirring rod, and an angle is formed between the upper stirring rod and the lower stirring rod; the upper stirring rod has a plurality of through holes.

[0026] Furthermore, the angle range is 30°-60°.

[0027] The beneficial effect of adopting the above-mentioned further technical solution is that it can increase the contact between the grinding material and the upper stirring rod, the lower stirring rod and the baffle, thereby achieving sufficient grinding and improving the grinding efficiency; at the same time, the design of the through hole on the upper stirring rod can prevent the grinding material from accumulating on the upper stirring rod.

[0028] Furthermore, the distance between the bottom of the rack and the ground is 20cm-30cm.

[0029] The beneficial effect of adopting the above further technical solution is that it is convenient for manual collection of the ground material falling out of the discharge port.

[0030] Furthermore, the fineness of the sieve is 1.25um.

[0031] The beneficial effect of adopting the above-mentioned further technical solution is that the screen fineness is designed to be 1.25um, that is, the ground material with a fineness above 1.25um will be blocked by the screen for further grinding, while the ground material with a fineness below 1.25um will pass through the screen into the discharge port for collection, thereby fully ensuring the grinding effect.
