Description

Technical Field

[0001] This utility model relates to a scraper conveyor for preventing scraper damage, and belongs to the technical field of coal conveying equipment. Background Technology

[0002] After a new filter press workshop in a coal preparation plant was put into operation, coal sludge frequently accumulated under the chain due to design and installation angle issues with the scraper during production. This resulted in uneven stress on the chains on both sides of the scraper, causing the chains to be of different lengths. In severe cases, the chains would even break or the scraper would bend. To avoid equipment damage, the scraper machine needed to be stopped after running for a period of time to clean the bottom plate and the coal sludge under the chain. The cleaning process was time-consuming, labor-intensive, and posed a high safety risk, while also affecting the efficiency of tailings sludge treatment. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a scraper conveyor that prevents damage to the scraper, so as to solve the technical problems existing in the prior art.

[0004] The technical solution adopted by this utility model is as follows: a scraper conveyor for preventing scraper damage, including a scraper conveyor body and a pressure plate fixed on the inner side wall of the scraper conveyor body. The pressure plate is parallel to the bottom of the trough of the scraper conveyor body and is located above the chains on both sides of the scraper conveyor body.

[0005] Preferably, the pressure plate is a 10# I-beam.

[0006] Preferably, the two ends of the pressure plate are welded with arc-shaped chamfers that match the arc-shaped portion of the chain of the scraper conveyor body.

[0007] Preferably, the pressure plate is installed 120-130mm above the bottom of the trough of the scraper conveyor body.

[0008] The beneficial effects of this utility model are:

[0009] 1. Compared with the prior art, this utility model sets up a pressure plate and an arc-shaped plate with chamfered corners to press the chains on both sides under the pressure plate. The scraper can directly scrape the coal sludge in the conveyor trough, preventing the accumulation of coal sludge inside the scraper, eliminating the situation of the scraper chain padding, reducing the workload of the operators, reducing the safety risks of operators entering the scraper to clean the padding chain, and ensuring the continuity of production.

[0010] 2. After this utility model was put into use in a certain mine, it could increase the operation of 4 filter presses per day, improving work efficiency. Based on each filter press working 5 cycles per shift, and each cycle producing 11 tons of dry coal slime, the increase in coal slime production per shift is 220 tons. Simultaneously, it reduces the number of people needed to clean the scraper conveyor chain by 2 per day, reducing the labor intensity of employees. Based on an employee wage of 5000 yuan / month, this reduces labor costs by 10000 yuan / month, resulting in an annual reduction of 120,000 yuan. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the installation structure of this utility model.

[0012] Figure 2 yes Figure 1 View from AA.

[0013] The reference numerals in the accompanying drawings include: scraper conveyor body 1, chain 2, pressure plate 3, and chamfered arc plate 4. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] Example 1:

[0016] Scraper conveyors that prevent scraper damage, such as Figures 1-2 The system includes a scraper conveyor body 1, which has an existing structure, and a pressure plate 3 fixed to the side wall of the scraper conveyor body 1. The pressure plate 3 is a 10# I-beam. The lower end of the pressure plate 3 is parallel to the bottom of the trough of the scraper conveyor body 1. The length of the pressure plate 3 is 2.4m. The pressure plate 3 is located above the chains 2 on both sides of the scraper conveyor body 1 and 120mm away from the bottom of the trough.

[0017] In this embodiment, the two ends of the pressure plate 3 are welded with arc-shaped plate chamfers 4 that match the arc-shaped part of the chain 2 of the scraper conveyor body 1.

[0018] In this embodiment, by setting a pressure plate 3 and an arc-shaped plate chamfer 4, the chains 2 on both sides are pressed under the pressure plate 3 to prevent coal slurry from accumulating inside the scraper conveyor body 1 and eliminate the situation of chain padding in the scraper conveyor body 1.

[0019] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
