Description

Technical Field

[0001] The utility model relates to the technical field of pulverizing devices, in particular to a coal pulverizing device for energy saving in factories. Background Art

[0002] In order to effectively utilize coal and achieve the goal of energy conservation and environmental protection, it is necessary to ensure that the coal can be fully burned, which requires the coal to be crushed.

[0003] The current coal pulverizing devices mostly adopt single-stage pulverization, which has low efficiency. At the same time, the coal particles after pulverization are large and cannot be fully burned. At the same time, the working state of the device is fixed and cannot be adjusted, resulting in energy waste.

[0004] A patent with announcement number CN206746665U is disclosed in the prior art, and its name is coal crushing device for energy saving in factories. The scheme includes a frame, a conveyor belt is installed in the middle of the lower end of the frame, an auxiliary support frame is installed at the lower end of one side of the conveyor belt, a conveying motor is installed on one side of the auxiliary support frame, a box is installed on the upper end of the frame, a controller is installed on the lower front side of the box, a feed hopper is installed on the upper end of the box, a one-way feed valve is installed on the lower end of the feed hopper, a first motor is installed on the upper part of one side of the box, a crushing shaft is installed on the shaft end of the first motor, a second motor is installed on the lower part of one side of the box, a driving gear roller is installed on the shaft end of the second motor, and a driven gear roller is installed on one side of the lower part of the box. The utility model adopts two-stage crushing, which can crush coal into smaller particles, can observe the crushing situation in real time, and adjust the working frequency. While ensuring the crushing effect, the working frequency can be reasonably adjusted to save energy.

[0005] As the existing technologies including the above patents are used, their shortcomings are gradually exposed, mainly in the following aspects:

[0006] First, when the size of the crushed particles needs to be adjusted during the existing coal crushing, only the spacing of the crushing structure changes, and the size of the feed port is fixed and cannot be adjusted according to the size of the crushed particles. This prevents larger coal blocks from entering the crushing box, reducing the crushing efficiency.

[0007] Second, after the existing pulverizing device pulverizes the coal block, the coal powder and the particles are mixed together. In order not to affect the combustion of the boiler, subsequent equipment is required to separate the coal powder, which increases the labor intensity.

[0008] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
