Description

Viscous material crusher

technical field

The utility model relates to coal quality analysis and sampling equipment, in particular to a crusher for crushing sticky and wet coal materials.

Background technique

In the commercial coal sampling system, the particle size of the collected coal sample must be broken to less than 25mm before it can be divided. In order to reduce dust, raw coal must maintain a high humidity during transportation. This kind of coal has high water content and high viscosity. Due to the impact of the hammer head of the ring hammer crusher on the material, the sticky and wet material hits the fixed crushing plate in front of the rotor at a very high speed and adheres firmly to it. With the continuous beating of the hammer head, the material will accumulate continuously, causing blockage at the entrance of the crusher. In addition, even for relatively dry samples, when the instantaneous coal flow rate is greater than the production capacity of the crusher, it will also accumulate at the entrance. Arching and blocking the crusher. Therefore, whether it is a single-rotor or double-rotor hammer crusher, it cannot crush sticky and wet materials.

Utility model content

Aiming at the deficiencies in the prior art, the utility model aims to provide a crusher specially used for crushing materials with high humidity and strong adhesion.

The technical scheme that the utility model adopts is:

A crusher for viscous and wet materials, comprising a machine body and a hammer head inside. The top of the machine body is provided with a feeding port, and the bottom is provided with a hopper.

The crawler-type strike plate is vertically arranged in a slope shape, and a pair of synchronous sprockets are respectively fixed on the upper and lower transmission shafts, and a strike plate is fixed on each chain link, and the motor drives the transmission shaft to drive the sprocket to rotate continuously , forming a movable broken plate.

The bottom of the area where the crawler strike plate is opposite to the hammer head is provided with a backing plate that can withstand the impact force of the hammer head.

The backing plate is fixed in the body through the backing plate mounting bracket.

The crawler strike plate is driven by a drive sprocket driven by a separate motor through a transmission shaft.

The outer side of the body is provided with a chain tensioning device at both ends of the upper drive shaft of the crawler strike plate.

The feed inlet is provided with a material guide plate in front of the crawler strike plate.

The wall plate of the body is equipped with a scraper specially for scraping the remaining material on the strike plate on the rear side of the crawler strike plate.

The scraper is a pull-in scraper.

The bottom of the hammer head is provided with a curved sieve plate.

The utility model replaces the crushing plate in front of the rotor of the hammer crusher with a rotatable crawler-type strike plate. When the material is fed to the strike plate, it will be forced to be fed into the action range of the hammer head with the rotation of the strike plate, and the material bonded to the strike plate will be swept away by the hammer head. The rotary scraper can automatically scrape off the remaining material. On the one hand, this crawler-type rotary bearing plate can prevent materials from accumulating at the entrance of the crushing chamber; Problems with sticky and wet materials and material jamming due to arching at the crusher inlet.

Detailed ways

Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.

As shown in Figures 1 and 2, the top of the viscous material crusher is provided with a feed inlet, with a hammer 9 inside, a lower hopper 11 at the bottom, an arc-shaped sieve plate 10 at the bottom of the hammer, and a front There are crawler-type strike plates that can be rotated, and the crawler-type strike plates are vertically arranged in a slope shape. A pair of synchronous sprockets are respectively fixed on the upper and lower drive shafts, and a strike plate 8 is fixed on each chain link. The driving sprocket 4 is driven to rotate by a separate motor 12 through the transmission shaft 14, and the strike plate 8 is continuously rotated by the chain 6 like a tank crawler to form a movable crushing plate. The bottom is provided with a backing plate 5, which can withstand the impact force of the hammer head 9 and improves the crushing efficiency. The backing plate 5 is fixed in the body 1 by the backing plate mounting bracket 15, and the two ends of the upper transmission shaft of the crawler-type striking plate are arranged on the outside of the body. There is a chain tensioning device 16, the feed inlet is provided with a material guide plate 7 in front of the crawler strike plate, and the wall plate of the body 1 is equipped with a pull-in scraper 3 on the rear side of the crawler strike plate, which is specially used for scraping. Sweep the remaining material on the striking plate 8.

When working, the motor 12 drives the transmission shaft 14, the driving sprocket 4 and the chain 6 to rotate, and the bearing plate 8 fixed on the chain 6 rotates continuously like the crawler of a tank. Under the action of hitting, it hits the strike plate 8 at a very high speed, and some materials may adhere to the strike plate 8. As the strike plate moves downward, the adhered materials are forced to be fed to the hammer. Within the scope of action of the head 9, it is swept away by the hammer head. With the rotation of the bearing plate 8, the plug-in scraper 3 automatically scrapes off the remaining material.

The utility model is not limited to the above-mentioned best implementation mode, and anyone can draw other various forms of products under the enlightenment of the present invention. For example, the crawler strike plate can also be realized by belt transmission, and the strike plate is fixed on the belt, but the strike plate must be movable, which can prevent material accumulation and also destroy the formation of arching. But no matter any changes are made in its shape or structure, all technical solutions identical or similar to the utility model are all within its protection scope.
