Description

Technical Field

[0001] The utility model relates to the technical field of roller press auxiliary equipment, in particular to an active anti-impact device for a roller press. Background Art

[0002] Material roller press is a common industrial equipment, mainly used for processing and pressurizing materials. It consists of one or more pairs of rollers, and the rolling and deformation of materials are achieved through the rotation of the rollers. The working principle of the material roller press is to place the material between the rollers, and then the rollers rotate to make the material subject to roller pressure, thereby changing the shape, density and mechanical properties of the material. The rollers are usually made of solid metal materials with smooth surfaces to reduce friction on the materials. Material roller presses are widely used in many industries, including metallurgy, chemicals, building materials, papermaking, food processing, etc. It can be used to press powdered or granular materials, such as powders, granules, ores, chemical raw materials, etc.

[0003] When the current material roller press processes materials, the materials usually enter the roller press through the roller press chute and hydraulic plug plate. During the operation of the roller press, the material rushing phenomenon is prone to occur. The material rushing phenomenon refers to the fact that during the operation of the roller press, due to various reasons, the material is not effectively rolled at the feed end and directly passes through the roller shaft. Among them, the mismatch of feed speed is a more common cause of material rushing in the roller press:

[0004] When there is material rushing inside the roller press due to abnormal feeding, the roller press will intercept the material through the hydraulic plug plate, but the hydraulic plug plate moves slowly, and it is difficult to quickly close the material channel, thus blocking the continued addition of material. The roller press is prone to process failures such as material rushing causing the roller bucket current to jump high.

[0005] In summary, there is a need for an active anti-collision device for a roller press that can quickly intercept materials. Utility Model Content

[0037] The working principle and use process of this utility model:

[0038] When using:

[0039] When the DCS system inside the roller press 6 detects that the roller bucket lifting current is higher than the set value, it can be determined that the roller press 6 is in poor working condition, the material is enriched and the material rushing phenomenon is occurring. At this time, the cylinder 5 sends air into the interception box 21, so that the air is compressed and gathered on the side of the push plate 22 in the interception box 21. When the material rushing phenomenon occurs, the hydraulic rod 32 in the positioning mechanism 3 controls the positioning plate 33 to move upward. When the positioning plate 33 is separated from the push plate 22, the compressed air on the side of the push plate 22 and the spring 24 can push the push plate 22 to move quickly inside the interception box 21. At this time, the interception plate 23 on the side of the push plate 22 can quickly enter the interception cylinder 1 to intercept the material entering the roller press 6, thereby avoiding the serious fault of the roller bucket being pressed to death due to the material rushing of the roller press 6.

[0040] During the interception process:

[0041] The electric push rod 42 in the reinforcement mechanism 4 controls the reinforcement block 43 to move into the interception tube 1. The reinforcement block 43 entering the interception tube 1 will move under the interception plate 23. The reinforcement block 43 under the interception plate 23 can support the interception plate 23 and improve the firmness of the interception plate 23.
