Detachable multifunctional feeding device of dry grinding equipment and its disassembly method

Abstract

A detachable multi-functional feeding device for dry grinding equipment and a method for disassembling and assembling thereof, relating to a feeding device for dry grinding equipment and a method for disassembling and assembling the same. A horizontal feeding chute is provided, and the feeding chute There are two combined hoppers that are docked together and have different slopes inside. The two combined hoppers are composed of U-shaped wear-resistant components and wear-resistant side plates. The U-shaped wear-resistant components consist of a bottom plate and two The side plate on the side, and the rib plate set between the bottom plate and the side plate, the wear-resistant side plate is set on both sides of the front of the bottom plate, the two combined hoppers are connected to the feeder through their respective wear-resistant side plates and side plates The two fixing plates arranged inside the material chute are detachably connected by a plurality of mortise bolts. By removing the U-shaped wear-resistant components of the combined hopper and the tenon bolts connecting the fixed plate, the wearing parts of the feeding device can be disassembled and replaced. The invention can conveniently disassemble and replace the wearable parts of the feeding device, and at the same time make it a passage for maintenance personnel to enter the grinding chamber.

Description

technical field [0001] The invention relates to a feeding device of dry grinding equipment and a disassembling method thereof, in particular to a detachable multifunctional feeding device of dry grinding equipment and a disassembling method thereof. Background technique [0002] Dry ball mill is a typical equipment for crushing materials after crushing, and is mainly used in chemical industry, mineral processing, building materials, metallurgy and other industries. The cement mill feeding device is an important part for conveying materials into the tube mill for grinding. It is composed of a feed inlet, a feed chute, a feed liner and other accessories. The feed liner is welded and assembled at a certain inclination angle. On the feed chute, it plays the role of protecting the feed chute and delaying its wear. The life of the feed liner is directly related to the operation rate and maintenance cost of the equipment. [0003] When working, the material falls on the feeding li...

AI Technical Summary

Problems solved by technology

[0004] Due to the unreasonable inclination angle of the feed liner, there will be material stoppage and material staining. The blocked material will directly enter the feed chute through the gap of the feed liner. When the accumulated material cannot be discharged in time and becomes return material, It will block the feed inlet, resulting in a decrease in mill productivity; too much material may also overflow through the air inlet and cause environmental pollution

[0005] In addition, when there is a problem in the existing dry grinding equipment cabin, it is shut down for maintenance, or when the grinding body is worn to a certain extent and needs to be added, and when the technician needs to sample the material in the mill, it is necessary to remove the grinding wheel. The grinding door, grinding door liner, pressure beam, gasket, gap filler and various accessories of the equipment are not only troublesome to disassemble, but also the grinding body is lifted and thrown by the liner with certain structural characteristics during the movement of the mill. After the mill runs for a period of time, the material is broken through the interaction between the grinding body and the material, and the grinding body is lost to tiny particles, and some of the tiny particles can enter the gap between the mill door liner and the cylinder liner Between them, the grinding door and the lining board of the grinding door are firmly stuck, which makes it difficult to disassemble the grinding door. According to the field investigation, not only special tools are required to disassemble the grinding door, but also difficult to disassemble, time-consuming and laborious, and people have to be removed if necessary. All the liners around the hole are removed, which greatly reduces the operating rate of the equipment

In addition, the grinding body is generally added through the grinding door. The grinding door is far away from the starting position of the first warehouse. During the operation of the mill, the grinding body is gradually brought up and thrown to the side far from the starting position to smash the material. Therefore, a There are fewer grinding bodies and more materials at the initial position of the warehouse, and the grinding efficiency is poor, which leads to the shortening of the effective grinding length of the first chamber of the mill, which seriously affects the output
