Problems solved by technology

[0004] The purpose of the present invention is to solve the problems existing in the prior art during wet grinding of raw material powder by wet mills. Due to the high speed of the equipment during feeding, the raw material powder cannot be quickly dispersed, and the powder is accumulated on the surface of the slurry, and the The rapid rotation of the material raises a large amount of dust, which leads to the disadvantage of harsh working environment, and proposes a tilting wet mill for high-strength cemented carbide grinding

Embodiment 1

[0022] refer to figure 1 and 7 , a tilting wet grinder for grinding high-strength cemented carbide, including a support 1, the top of the support 1 is fixedly mounted with two symmetrical fixed plates 2 by welding, and the two fixed plates 2 are provided with There is a first through hole, a first rotating shaft 3 is rotatably installed in the two first through holes, one end of the two first rotating shafts 3 is fixedly connected with the same mounting seat 4 by welding, and a first mounting seat 4 is provided on the mounting seat 4 A feeding port 5 is rotatably installed in the first installation hole, and a cylindrical body 6 is fixedly connected to the feeding port 5 by welding. The outer side of the cylindrical body 6 is rotatably installed with an annular sleeve 7, and the top of the mounting seat 4 is fixedly installed by welding. There is a box body 8, two symmetrical rectangular plates 9 are installed on the top of the support 1 by welding, a tilting mechanism is pro...

Embodiment 2

[0030] The difference from the first embodiment is that: the top of the box body 8 is fixedly installed with a controller and an alarm, the controller is connected with the alarm, an air flow meter is fixedly installed in the air outlet, and the air flow meter is connected with the controller. The three rotating shafts 23 drive the impeller 26 to rotate. The suction generated by the impeller 26 can absorb the dust generated in the wet grinding process through the connecting pipe 27 and the dust suction port 30. The filter plate 13 can filter the dust. When the filter plate 13 filters more When there is dust, the air flow rate in the box 1 decreases, and the air flow meter can detect the air flow rate in the box 8. When the air flow rate reaches a certain threshold, the air flow meter can control the alarm through the controller to issue an alarm reminder, so as to remind The staff cleans up the filtered dust in time.

Abstract

The invention belongs to the field of wet mills, particularly relates to a tilting-type wet mill for grinding high-strength hard alloy, and aims to solve the problems that raw material powder cannot be quickly dispersed and is accumulated on the surface of slurry due to high rotating speed of equipment during feeding in the wet milling process of the raw material powder by the conventional wet mill, and a large amount of dust is raised along with quick rotation of the slurry, so that the raw material powder cannot be quickly dispersed. According to the technical scheme, the device comprises a support, two symmetrical fixing plates are fixedly mounted at the top of the support through welding, first through holes are formed in the two fixing plates, first rotating shafts are rotationally mounted in the two first through holes, and the first rotating shafts are arranged in the first rotating shafts; according to the wet grinding device for the raw material powder, in the wet grinding process of the raw material powder, a large amount of generated dust can be fully treated conveniently, so that the working environment can be effectively improved, the structure is simple, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of wet mills, in particular to a tiltable wet mill used for grinding high-strength hard alloys. Background technique [0002] When making cemented carbide, the selected raw material powder has a particle size between 1 and 2 microns, and the purity is very high. The raw materials are batched according to the prescribed composition ratio, and alcohol or other media are added to wet grinding in a wet ball mill to make them fully mixed and pulverized. After drying and sieving, a type of molding agent such as wax or glue is added. Sieve the mixture. Then, the mixture is granulated, pressed, and heated to a temperature close to the melting point of the binder metal (1300-1500 °C), the hardened phase and the binder metal will form an eutectic alloy. After cooling, the hardened phases are distributed in the grid composed of the bonding metal and are closely connected with each other to form a solid whole. Wet ba...
