Description

Technical Field

[0001] This utility model relates to the technical field of pendulum mills, specifically to a sealing device for a pendulum mill. Background Technology

[0002] The pendulum mill is a highly efficient grinding equipment. Its rotor rotates at high speed, causing the grinding disc and material to vibrate at high frequency and large amplitude. This vibration, through the impact of the pendulum frequency, breaks down large refractory particles, thus meeting the requirements for grinding. This smooth grinding process can efficiently process various refractory materials of different hardnesses, such as high-alumina bauxite and corundum. It is also suitable for processing refractory materials with different properties, such as hard, high-density, medium-hardness, ordinary clay, glassy, ​​and refractory materials in corrosive environments.

[0003] When feeding materials into a pendulum mill, sealing is typically required. This is because pendulum mills work by grinding materials through vibration and impact; without sealing, dust can fly, affecting the working environment and employee health. Furthermore, unsealed equipment is more susceptible to corrosion from dust and impurities, requiring more maintenance and increasing operating costs. Therefore, we propose a sealing device for pendulum mills to ensure the sealing of the feed inlet. Utility Model Content

[0004] The purpose of this invention is to provide a sealing device for a pendulum mill to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing device for a pendulum mill, comprising a pendulum mill, wherein a feed pipe is fixedly connected to the side wall of the pendulum mill, and a sealing structure is provided at the other end of the feed pipe.

[0006] Preferably, the sealing structure includes a flange, which is connected to the end flange of the feed pipe. A cloth bag is fixedly connected to the inner ring wall of the flange. A rubber ring is glued to the inner wall of the cloth bag. Semicircular plates are symmetrically sleeved on the outer wall of the cloth bag. The connection between the two semicircular plates is fixedly connected by bolts.

[0007] Preferably, a side plate is fixedly connected to the side wall of the feed pipe, a fan is fixedly connected to the upper surface of the side plate, and a side pipe is fixedly connected to the output end of the fan, with the side pipe passing through the side wall of the feed pipe via an interference fit.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: When using a pendulum mill, a sealing structure is pre-installed at the end of the feed pipe. One end of the bag tube is a rubber tube and the other end is made of cloth. The bag end of the bag tube is connected to the pipe of the discharge equipment. At the same time, a rubber ring is installed inside the bag tube, and it is clamped by symmetrical semicircular plates on the outside to fix the bag tube to the outside of the pipe of the discharge equipment for sealing. Different sizes of semicircular plates can also be selected according to the specifications of the pipe to ensure the overall sealing effect and avoid dust flying. At the same time, a fan is installed at one end of the feed pipe to blow air inward when discharging, which increases the additional limit on the material and prevents the material from flowing back and generating dust. Moreover, the bag tube has a simple structure, is easy to install and disassemble, and can be easily cleaned and the bag replaced. Attached Figure Description
