Description

Technical Field

[0001] This utility model relates to the technical field of twin-shaft chain crushers, specifically a device for quickly cleaning up material adhesion in a twin-shaft chain crusher using a hydraulic mechanism. Background Technology

[0002] In fertilizer production, large raw materials or agglomerated materials need to be crushed into fine powder for subsequent processing. Due to the characteristics of fertilizer production raw materials, chain crushers are used for crushing. Chain crushers are suitable for crushing lumpy materials in compound fertilizer production and are also widely used in chemical, building materials, and mining industries. The main working part of a chain crusher is a rotor with a steel ring chain. One end of the chain is connected to the rotor, and the other end of the chain is fitted with a wear-resistant steel chain head. Chain crushers are impact crushers, crushing materials by impacting them with a high-speed rotating chain. When materials enter the machine and collide with the high-speed rotating chain, they undergo multiple impacts, compression, and crushing, ultimately forming fine powder or particles smaller than 3mm. This impact crushing method is particularly suitable for processing lumpy and agglomerated materials in fertilizer production.

[0003] When the crusher is working, the material falls into the crushing cylinder from the feed inlet and is crushed by the rotating crushing chain. Under the action of impact force and centrifugal force, the crushed material splashes onto the inner wall of the crushing cylinder, bounces back and falls down, and is discharged from the bottom of the crushing cylinder. During this process, due to the high moisture content of the material, coupled with the huge centrifugal force and impact force, the powdery material will gradually and in multiple layers adhere to the inner wall of the crushing cylinder and the inner surface of the cylinder top sealing plate. Therefore, during the production process, it is necessary to frequently stop the machine to clean the adhering material on the inner wall of the crushing cylinder and the inner surface of the cylinder top sealing plate in order to ensure the normal operation of production and the safety of the equipment.

[0004] However, common cleaning devices for material adhesion in twin-shaft chain crushers typically only clean the material on the cylinder wall. When too much material accumulates on the chain, manual cleaning is required. Therefore, this application proposes a device for quickly cleaning material adhesion in twin-shaft chain crushers using a hydraulic mechanism. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a device for quickly cleaning material adhering to a twin-shaft chain crusher using a hydraulic mechanism. This device has the advantages of cleaning the cylinder wall and the chain simultaneously, solving the problem that common material adhering to twin-shaft chain crushers typically only clean the material on the cylinder wall, requiring manual cleaning when excessive material accumulates on the chain.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for quickly cleaning material adhesion in a dual-shaft chain crusher using a hydraulic mechanism, comprising a cylinder, two crushing shafts rotatably mounted on the inner top wall of the cylinder, a crushing chain fixedly mounted on the surface of the crushing shafts, and a cleaning component slidably mounted on the inner side wall of the cylinder;

[0007] The cleaning assembly includes an annular scraper slidably mounted on the inner side wall of the cylinder and an inner cleaning ring sleeved on the surface of the crushing shaft. An installation rod is fixedly mounted on the inner side wall of the annular scraper, one end of which is welded to the surface of the inner cleaning ring. A cleaning brush is fixedly mounted on the inner side wall of the inner cleaning ring.

[0008] Furthermore, two crushing motors are fixedly installed on the top of the cylinder, and the output shafts of the two crushing motors are respectively fixedly connected to the top of the crushing shaft.

[0009] Furthermore, a mounting base plate is fixedly installed on the surface of the cylinder near the bottom, and a mounting hole is opened on the top of the mounting base plate. A mounting top plate is fixedly installed on the surface of the cylinder near the top, and a through hole is opened on the top of the mounting top plate. Two crushing motors are located inside the through hole.

[0010] Furthermore, four hydraulic cylinders are fixedly installed between the mounting base plate and the mounting top plate, and a lifting plate is fixedly installed at the movable end of the hydraulic cylinders extending above the mounting top plate.

[0011] Furthermore, four connecting rods are fixedly installed at the bottom of the lifting plate, and four arc-shaped through holes adapted to the connecting rods are opened at the top of the cylinder. The bottom end of the connecting rod passes through the arc-shaped through hole and is fixedly connected to the top of the annular scraper.

[0012] Furthermore, a feed inlet is provided at the top center of the cylinder, and a feed pipe adapted to the feed inlet is fixedly installed at the top center of the cylinder. The top of the feed pipe extends above the highest point of the mounting plate, and a feed hopper is fixedly installed at the top of the feed pipe.

[0013] Compared with the prior art, this utility model provides a device for quickly cleaning material adhering to a twin-shaft chain crusher using a hydraulic mechanism, which has the following beneficial effects:

[0014] This device utilizes a hydraulic mechanism to quickly clean material adhering to a twin-shaft chain crusher. A cleaning component is installed on the inner wall of the cylinder. A ring scraper moves downwards from the top inner wall of the cylinder, scraping off material adhering to the inner wall. Simultaneously, the ring scraper moves a mounting rod downwards, causing an internal cleaning ring to move downwards. This allows the cleaning brush inside the internal cleaning ring to clean the drooping crushing chain, removing material adhering to its surface. This solves the problem that common twin-shaft chain crusher material adhering devices typically only clean material on the cylinder wall, requiring manual cleaning when excessive material accumulates on the chain.
