Abstract
The utility model relates to a feeding and discharging hopper of a steel-ball coal mill, which comprises a hopper. The utility model is characterized in that a wear-resistant lining plate is arranged on the inner wall of the hopper, and the wear-resistant lining plate and the hopper are connected by bolts. As the wear-resistant lining plate and the hopper are connected by the bolts, the lining plate is convenient to replace after being worn out. The utility model has the advantages of labor saving and force saving, and avoids unnecessary waste.
Description
The utility model be low speed coal mill into and out of hopper.
The feed hopper and the discharge bucket of existing low speed coal mill are made with the B3F steel plate; since be subjected to the impact of material, shorter into and out of the service life of hopper, so generally adopt high-abrasive material to make liner plate; be welded in the hopper; with the protection hopper, but also be limited the service life of abrasion-proof backing block, after wearing and tearing after a while, just needing replacing; the abrasion-proof backing block of Type of Welding is changed very trouble; sometimes be time saving and energy saving, be about to hopper and take together and abandon, cause very big waste.
The purpose of this utility model provides a kind of novel steel and asks coal pulverizer into and out of hopper, and its liner plate can be changed very easily, avoids causing waste, and saves labor.
The purpose of this utility model is achieved in that it comprises hopper, it is characterized in that abrasion-proof backing block being installed at the hopper inwall, be connected with bolt between abrasion-proof backing block and the hopper, preferably be connected with dormant bolt, in order to save raw material, liner plate can be made semicircle, be installed in the Lower Half of hopper.
The utility model adopts bolt to connect liner plate and hopper, makes the later replacing of wear liner very convenient, saves labor, and has avoided unnecessary waste.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, the 1st, abrasion-proof backing block for saving material, is made into semicircle, is installed in the lower half circle of hopper 2 inwalls, with dormant bolt 3 liner plate and hopper is tightened together.
Claims (3)
1, low speed coal mill is into and out of hopper, and it comprises hopper, it is characterized in that at the hopper inwall abrasion-proof backing block being installed, and is connected with bolt between abrasion-proof backing block and the hopper.
2, said according to claim 1 into and out of hopper, it is characterized in that being connected with dormant bolt between liner plate and the hopper.
3, said according to claim 1 into and out of hopper, it is characterized in that liner plate makes semicircle, be installed in the Lower Half of hopper.
