Description

Technical Field

[0001] The invention relates to the technical field of dust removal, and in particular to a dust removal device for a micro-positive pressure bearing seat. Background Art

[0002] Belt conveyor is a friction-driven machine that transports materials in a continuous manner. It is mainly composed of a frame, conveyor belt, rollers, drums, tensioning devices, transmission devices, etc. It can form a material conveying process from the initial feeding point to the final unloading point on a certain conveying line. It can convey both bulk materials and pieced items. In addition to pure material conveying, it can also cooperate with the requirements of the process in the production process of various industrial enterprises to form a rhythmic flow operation transportation line.

[0003] As an important part of the belt conveyor, the stability of the roller's operation is crucial to the conveying system. In the port bulk material conveying environment, dust pollution is serious. The roller bearing seat is easily contaminated by dust. Dust entering the bearing seat will not only cause the lubricating oil to deteriorate and affect the bearing lubrication effect, but also reduce the bearing life. Under long-term action, the roller is prone to failure, which has an adverse effect on production operations.

[0004] In view of the above-mentioned problem that the lubrication effect of the roller bearing is reduced and the service life of the bearing is shortened after being affected by dust, a micro-positive pressure bearing seat dust removal device is needed. Summary of the invention

[0005] Aiming at the problem that the lubrication effect of the current roller bearing is reduced and the service life of the bearing is shortened after being affected by dust, the present invention proposes a micro-positive pressure bearing seat dust removal device to solve the above problem.

[0006] The present invention proposes a micro-positive pressure bearing seat dust removal device, comprising a bearing seat body, a dust cover installed on the bearing seat body, an air pressure sensor installed on the dust cover, an air pipe connected to the dust cover, an electric regulating valve installed on the air pipe, one end of the air pipe is connected to an air storage tank, the air inlet of the air storage tank is connected to an air compressor, and a controller is installed on the air compressor. When in use, most of the dust can be prevented from entering the bearing through the dust cover, and then the air outlet is controlled by the electric regulating valve to form a micro-positive pressure state inside the dust cover, and the dust close to the gap of the dust cover is blown away to prevent dust from entering the bearing. The air pressure can be monitored in real time through the air pressure sensor. When the air pressure is insufficient, the electric regulating valve is controlled by the controller to operate to increase the air outlet so that the inside of the dust cover always maintains a micro-positive pressure state.

[0007] Furthermore, the dust cover is made of stainless steel.

[0008] Furthermore, the air pressure sensor adopts a differential pressure sensor.

[0009] Furthermore, the air pressure sensor is connected to the controller via a wireless signal.

[0010] Furthermore, the electric control valve adopts an electric single-seat control valve.

[0011] Furthermore, the electric regulating valve is electrically connected to the controller.

[0012] Furthermore, a safety valve and a pressure gauge are installed on the gas storage tank, and the safety of the entire device can be improved through the safety valve.

[0013] Furthermore, the air pipe adopts a metal flexible pipe.

[0014] The beneficial effects of the present invention are: 1: Based on the poor on-site operating environment of the belt conveyor and serious dust pollution, the device uses the air pressure difference to change the direction of air circulation, so that the airflow flows from the inside of the stainless steel dust cover to the outside, preventing dust from entering; 2: External dust cannot enter the stainless steel dust cover, ensuring that the bearing seat is in a relatively clean and dry space. Dust does not enter the bearing seat, greatly improving the service life of the bearing. At the same time, air circulation can take away the heat generated by the rotation of the drum, ensuring that the bearing is in a relatively low temperature environment; 3: The micro-positive pressure dust removal system has a simple structure and is easy to install and maintain; 4: The automatic control system can be used to achieve unattended operation, reduce operation and maintenance, and save maintenance costs.
