Description

A scraper cleaning machine and its assembly and use method

technical field

The invention belongs to the field of material conveying equipment, and more specifically relates to a scraper cleaning machine and its assembly and use method.

Background technique

Belt conveyor is a kind of machinery that is driven by friction to transport materials in a continuous manner. It is mainly composed of frame, conveyor belt, idler roller, roller, tensioning device, transmission device, etc. It can form a material conveying process from the initial feeding point to the final unloading point on a certain conveying line. It can not only transport broken materials, but also transport finished items. In addition to pure material transportation, it can also cooperate with the requirements of the technological process in the production process of various industrial enterprises to form a rhythmic assembly line. Belt conveyors can be divided into heavy belt conveyors such as mining belt conveyors according to their conveying capacity, and light belt conveyors such as those used in electronic plastics, food light industry, chemical and pharmaceutical industries. The belt conveyor has strong conveying capacity, long conveying distance, simple structure and easy maintenance, and can conveniently implement programmed control and automatic operation. The continuous or intermittent movement of the conveyor belt is used to transport the items below 100KG or powdery and granular items. It runs at high speed, stable, low noise, and can be transported up and down slopes.

Most of the powder in the sintering plant is conveyed by belt conveyors. The belt conveyor has a high belt speed and a high water content in the powder, so a large amount of sticky materials are produced under the deflection wheel at the head wheel position of the belt conveyor. , The spilling of materials is more serious, resulting in a lot of waste, and a large amount of material accumulated under the belt is not cleaned in time, causing the belt to wear and fail to work normally. Conventional belt cleaners, vibrating cleaning, spring cleaning, and brush cleaning cannot completely remove the spilled material, and the cleaning efficiency is low. If manual cleaning and blanking are used, the work intensity is not only high, but also the danger is high. It is necessary to stop the belt conveyor to proceed. production delays.

Compared with the above problems, the applicant has proposed a corresponding solution before, and applied for a patent named: a belt cleaning scraper conveyor, the application number is: 201620040981.7, which can better solve the above problems, but in During the long-term use, a series of problems have been found, mainly including: the chain is easy to loose; the synchronization of the two sides on both sides is poor, and it is prone to jamming; the chain is easy to fall off the roller; the connection between the scraper and the chain is loose, causing the scraper to fall off; The middle part of the chain will sink and collide with the frame, hindering the movement of the chain; the stability of the motor is poor.

Of course, there are also other solutions on this aspect, such as the Chinese patent publication number: CN 104590824 A, the publication date is: the patent document on May 6, 2015, which discloses a new type of buried scraper conveyor, which includes a nose Components, a plurality of connecting components, feeding components and tail components; the nose component includes a nose body, the top of the nose body is fixed with a deceleration motor through a deceleration frame, and the deceleration motor rotates to drive the small sprocket to rotate. The sprocket drives the large sprocket to rotate through the transmission chain. The rotation of the large sprocket drives the head wheel shaft to rotate. The head wheel shaft drives the head wheel fixed on the head wheel shaft to rotate. The head wheel drives the transmission chain to move, and the transmission chain drives the tail wheel to rotate. The chain moves along the upper guide rail and the lower guide rail during the rotation process, and the transmission chain transports the materials from the inlet to the outlet during the rotation of the head wheel and the tail wheel. The scraper transport device is easy to install and debug, runs smoothly, occupies a small area, and has a long service life, but its structure is relatively complicated and the production cost is high; in addition, its tail assembly is high and cannot be inserted into the belt conveyor Under the reversing pulley at the position of the head pulley, the width of the whole machine is narrow, so it cannot accept all the materials falling from the belt.

As another example, the Chinese patent publication number is: CN 202657656 U, and the publication date is: the patent document on January 9, 2013, which discloses a feed buffer device for a coal slime drying system, and its power transmission mechanism consists of a motor, a reducer , Composed of frequency conversion control system, the motor is connected with the reducer, and the reducer is connected with the scraper conveyor. The body of the buffer scraper conveyor is equipped with double-layer scrapers, the upper and lower layers of the double-layer scraper are arranged, the upper and lower scrapers are respectively opened with discharge ports, and the upper end of the buffer scraper conveyor is equipped with a slime buffer bin , The coal slime buffer bin is connected with the buffer scraper conveyor, and the bottom of the coal slime buffer bin is provided with a gate. Due to the use of the slime buffer bin and the scraper conveyor mechanism with a special structure, the discharge is stable. When the moisture content of the slime is large, there is no equipment adhesion, and the structure is reliable; the buffer bin is equipped with gate control, which can effectively adjust the drying system. Material volume: adopting frequency conversion control, it can flexibly control the feeding volume of the drying system, and ensure the uniformity of the drying system feeding, and reduce the operation failure rate compared with conventional conveyors. But this device is not suitable for the blanking cleaning of belt conveyor, conveying, and its chain is easy to loosen, easily shakes during operation, and operates unstable.
