Description

TECHNICAL FIELD

[0001] The application relates to the technical field of high-pressure roller mills, in particular to a self-adaptive automatic control device of a high-pressure roller mill BACKGROUND

[0002] The high-pressure roller mill is a kind of high-efficiency crushing equipment, which is widely applied to fine crushing and superfine crushing of ores and the like, and has the advantages of energy saving, high efficiency and small abrasion. The high-pressure roller mill implements quasi-static pressure crushing and layer crushing on materials through two oppositely rotating rollers. In addition, the high-pressure roller mill is widely applied to the fields of mining, metallurgy, chemical industry, building materials and engineering construction.

[0003] In the prior art, the patent with the publication number CN109174405A discloses a building ore high-pressure roller mill, a rack, a roller mill chamber arranged on the rack, a first high-pressure roller and a second high-pressure roller arranged in the roller mill chamber, a hydraulic drive device for driving the first and second high-pressure rollers to approach each other to crush materials, a material scattering chamber arranged on the side of the roller mill chamber, a discharge inclined cylinder arranged on the lower part of the roller mill chamber and penetrating into the material scattering chamber from the side of the material scattering chamber, a scattering device arranged in the material scattering chamber, and an outlet of the discharge inclined cylinder being located above the scattering device. A recovery crushing device is arranged for screening and secondary crushing of materials with relatively large particles. In the application, the crushing, scattering, screening and recovery processing operations can be directly performed in one device, so that the conveying time of materials between corresponding devices in each link is effectively shortened, and the work efficiency is greatly improved.

[0004] When the above-mentioned patent crushes materials, the materials need to be directly put into a feeding hopper. Since the position of the hopper is fixed, the materials directly fall between the two rollers, which is easy to cause uneven distribution of the materials on the rollers and cause over-accumulation of the materials at a single position.

If the materials are over-accumulated, the running resistance of the rollers is increased, and the service life of the rollers is reduced. Therefore, the self-adaptive automatic control device of the high-pressure roller mill is needed to meet the needs of people. SUMMARY

[0018] 3, beneficial effects

[0020] (1) The self-adaptive automatic control device of the high-pressure roller mill can use the conveying belt to send the material to the hopper, and the feeding motor and the driving motor can be turned on in the process. Under the action of the feeding motor, the material in the hopper can be sent to the two grinding rollers for crushing, and under the action of the driving motor, the cloth bin can reciprocate in the positioning frame, so that the material can be evenly laid between the two grinding rollers, the material is evenly distributed, and the situation that the material is excessively accumulated in a single position is prevented, so that the normal operation of the high-pressure roller mill is ensured, and the crushing effect of the grinding roller is improved.

[0021] (2) The self-adaptive automatic control device of the high-pressure roller mill, as the material between the two grinding rollers increases, the material will extrude the distance measuring plate upward. When the distance measuring plate is extruded and rises, the position sensor can sense the position change of the distance measuring plate and transmit a signal to the driver to control the feeding motor to reduce the speed and reduce the feeding speed. When the material on the two grinding rollers gradually decreases, the distance measuring plate will be pushed down under the action of the limiting spring. When the distance measuring plate is reset, the position sensor will sense and control the speed of the feeding motor through the driver to restore the feeding speed, so that the feeding speed can be controlled according to the amount of material remaining on the two grinding rollers, and the increase of the running resistance of the grinding roller caused by excessive accumulation of the material is avoided.

[0022] (3) The self-adaptive automatic control device of the high-pressure roller mill can reciprocate the extrusion plate under the action of the driving motor to extrude the distance measuring plate, press the distance measuring plate to the material between the two grinding rollers, press the material on the grinding roller, increase the contact effect and extrusion force between the material and the grinding roller, and make the material more easily form fine particles and micro-cracks, thereby further improving the crushing effect.

[0023] (4) The self-adaptive automatic control device of the high-pressure roller mill can drive the limiting plate to move on the pulley during the reciprocating movement of the cloth bin, and the pulley can roll along with the movement of the limiting plate, so that the cloth bin can move more smoothly during the movement, and the operation effect of the cloth bin is guaranteed.
