Description

A high-efficiency wet grinding equipment

technical field

The utility model relates to the technical field of grinding equipment, in particular to a high-efficiency wet grinding equipment.

Background technique

Wet grinding machines are widely used in various powder processing industries such as electronics, ceramics, chemicals, medicine, metallurgy, and environmental protection. Its working principle is: the pneumatic diaphragm pump sends the pre-mixed material into the grinding chamber, and the fast-circulating material achieves the purpose of grinding by stirring the intense grinding medium, and the ground material overflows through the overflow port on the baffle, and then Through the material circulation pipeline, it returns to the material circulation cylinder, and then the grinding material is further sent back to the grinding chamber through the pneumatic diaphragm pump for multiple cycle grinding. The fast-circulating material is conducive to obtaining a narrow particle size distribution through the agitation of the intense grinding medium layer, allowing smaller particles to pass through quickly, while relatively coarse particles have to stay for a long time, and the coarse particles are preferentially crushed Effect.

The wet grinding machine can also be used to crush many inorganic powder particles to achieve the purpose of controlling particle size and particle size distribution. These inorganic powder particles include calcium carbonate, calcium oxide, titanium dioxide, aluminum oxide, aluminum hydroxide, magnesium oxide, magnesium hydroxide, zinc borate, barium sulfate, etc. Media used for grinding include alumina, zirconia, silica, etc.

The grinding medium of the original wet grinding machine generally uses zirconia with a particle diameter of 1.5 to 3.0 mm. Due to the large particles, the grinding efficiency is relatively low. In order to improve the grinding efficiency, zirconia with a particle diameter of no more than 1.2 is generally used now. The hole diameter of the overflow hole on the baffle is 1mm. As the amount of grinding increases, part of the zirconia will be worn and the diameter will decrease accordingly. When the diameter of zirconia is less than 1mm, it will overflow with the material. This will contaminate the material.

Utility model content

The technical problem solved by the utility model is to provide a high-efficiency wet grinding equipment to solve the problems raised in the above-mentioned background technology.

The technical problems solved by the utility model are realized by the following technical solutions: a high-efficiency wet grinding equipment, including: a grinding chamber, a material circulation cylinder, a pneumatic diaphragm pump, a rod-cylindrical stirring shaft, a vibrator, and an ultrasonic generator. The grinding chamber is connected to the material circulation cylinder through a circulation pipeline. A pneumatic diaphragm pump is installed on the downstream of the circulation pipeline between the material circulation cylinder and the grinding chamber. An electromagnetic flowmeter is installed on the circulation pipeline on one side of the pneumatic diaphragm pump. The center of the grinding chamber There is a rod-cylindrical stirring shaft vertically, a baffle is installed on the upper part of the rod-cylindrical stirring shaft, overflow ports are provided on both sides of the baffle, a stainless steel screen is provided on the overflow port, and a vibrator is installed at the bottom of the grinding chamber. The interior is filled with grinding media, and ultrasonic generators are installed on both sides of the grinding chamber.

The ultrasonic generators on both sides of the grinding chamber are arranged symmetrically.

The rod-shaped stirring shaft is provided with several stirring side branches.

Compared with the prior art, the beneficial effect of the utility model is that: the utility model is provided with a 20-30 mesh stainless steel screen on the overflow port on the baffle plate of the grinder. After the material passes through the overflow port on the baffle, it needs to pass through a layer of stainless steel screen with smaller aperture for secondary filtration to prevent the grinding medium from overflowing with the material, which not only ensures the grinding efficiency of the wet mill, It also prevents the material from being polluted by the grinding medium; the stainless steel screen is fixed on the baffle by bolts, which is convenient for regular cleaning.

Detailed ways

In order to make the technical means, creative features, goals and effects of the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific illustrations.

As shown in Figure 1, a kind of high-efficiency wet grinding equipment includes: grinding chamber 1, material circulation cylinder 6, pneumatic diaphragm pump 7, rod-cylindrical stirring shaft 9, vibrator 10, ultrasonic generator 12, described grinding chamber 1 is connected to the material circulation cylinder 6 through a circulation pipeline, a pneumatic diaphragm pump 7 is installed on the downstream of the circulation pipeline between the material circulation cylinder 6 and the grinding chamber 1, and an electromagnetic flowmeter 11 is provided on the circulation pipeline on one side of the pneumatic diaphragm pump 7, The center of the grinding chamber is vertically equipped with a rod-shaped stirring shaft 9, and a baffle 2 is installed on the upper part of the rod-cylindrical stirring shaft 9, and overflow ports 3 are arranged on both sides of the baffle plate 2, and a stainless steel screen is arranged on the overflow port 3 4. A vibrator 10 is installed at the bottom of the grinding chamber 1 , the inside of the grinding chamber 1 is filled with grinding media 8 , and ultrasonic generators 12 are installed on both sides of the grinding chamber 1 .

The ultrasonic generators 12 on both sides of the grinding chamber 1 are arranged symmetrically.

Several stirring side branches are arranged on the rod-cylindrical stirring shaft 9 .

The working principle of the utility model is: the pneumatic diaphragm pump 7 sends the premixed material into the grinding chamber 1, and the grinding medium 8 is stirred by the rod-cylindrical stirring shaft 9, and the rapidly circulating material is crushed by stirring the intense grinding medium 8 For the purpose, the ground material overflows upwards through the overflow port 3 on the baffle plate 2, returns to the material circulation cylinder 6 through the circulation pipe, and then is sent back to the grinding chamber 1 through the pneumatic diaphragm pump 7 for repeated grinding cycles. During the grinding process, the cooling jacket 5 is cooled by circulating tap water to ensure that the grinding chamber 1 will not be damaged due to excessive temperature. The cycle time depends on the particle size of the final target product. The higher the product particle size requirement, the longer the cycle time.

In order to improve the grinding efficiency, the grinding medium 8 adopts zirconia with a particle diameter of 1000 Å, and the hole diameter of the overflow port 3 on the baffle plate 2 is 1mm. As the amount of grinding increases, part of the zirconia will wear out, and the diameter will increase accordingly. When the diameter of zirconia is less than 1mm, it will overflow with the material, which will pollute the material.

In the utility model, after the material passes through the overflow port 3 on the baffle plate 2, it needs to pass through a stainless steel screen 4 with a smaller aperture for secondary filtration to prevent fine zirconia from overflowing with the material, so that both It ensures the grinding efficiency of the wet mill and prevents the material from being polluted by zirconia. Moreover, the stainless steel screen 4 increases the material passing area without affecting the passing speed of the material. Because the stainless steel screen mesh 4 is fixed on the baffle plate 2 by bolts, it is convenient to clean it regularly.
