Description

Technical Field

[0001] The invention relates to the technical field of coal processing, in particular to a coal processing device for a boiler. Background Art

[0002] As an important equipment for heat energy conversion, the efficient and stable operation of coal-fired boilers is crucial for industrial production, heating and other fields. Coal is its main fuel, and its particle size, shape, humidity and other characteristics directly affect the combustion efficiency and pollutant emissions. Therefore, pre-treatment of coal, especially crushing, has become a key link in improving boiler performance.

[0003] The existing coal processing equipment, the hammer crusher, is an impact rotor crusher with a hammer. The hammer can not only revolve with the rotor, but also rotate around the hammer pin. After the material enters the crushing chamber, it is first crushed by the impact of the hammer rotating at high speed with the rotor. The crushed material also obtains kinetic energy from the hammer, rushes to the crushing plate at high speed, is crushed for the second time, and then falls on the screen plate, is further crushed by the extrusion and grinding of the hammer, and is discharged through the screen holes. After extrusion, the raw materials will fall on the screen below. Most of them are discharged by shaking the screen, and some of them that do not meet the requirements will also stay on the screen, and cannot be processed for the second time. Staying on the screen affects the discharge of the raw materials that meet the requirements. The effect is not good during use, and this needs to be improved. Summary of the invention

[0004] The purpose of the present invention is to provide a coal processing equipment for boilers to solve the problem in the above-mentioned background technology that the raw materials after extrusion will fall on the screen below, most of which are shaken off by the shaking screen for discharge, and some that do not meet the requirements will also remain on the screen and cannot be processed for the second time. The raw materials that remain on the screen affect the discharge of the raw materials that meet the requirements, resulting in poor effect during use.

The support is fixedly connected to the inner bottom end of the crushing equipment shell, and a hollow groove is provided inside the support. The vibration motor is connected to the inside of the support.

[0009] Furthermore, an elastic connection pad is fixedly connected to the top of the support member, and the screening plate member is fixedly connected to the top of the elastic connection pad.

The crushed coal falls to the bottom through the penetrating crushing groove, and then falls to the top of the screening plate. The three-level processing component setting ensures the crushing quality, and can also help crushing during the transmission process, with high use efficiency;

[0018] 2. The coal processing equipment for the boiler uses a pressure detection sensor to detect the weight due to the design of the secondary processing device.

The raw materials that meet the requirements need to be taken out before the fan is triggered to avoid the secondary processing of the coal that meets the requirements. Some of the coal that does not meet the requirements will not stay on the screen for a long time and can be processed secondary, which will not affect the discharge of the raw materials that meet the requirements;

[0019] 3. The coal processing equipment for boilers is provided with a screening device. After the coal falls onto the screening plate, the vibration motor inside the support can be started to drive the screening plate to shake for coal screening. The coal that meets the requirements will fall to the bottom. Then the user can open the door on the front of the crushing equipment shell to facilitate the removal of the coal.
