Description

Technical Field

[0001] The present invention relates to the technical field of material distribution for scraper conveyors, and in particular to a material distribution device for a scraper conveyor. Background Art

[0002] In the prior art, a scraper conveyor is often used to distribute and convey crushed powder materials such as coal. As shown in the attached Figure 1 figure, due to the action of its own gravity, the powder material falls from the discharge ports arranged in parallel under the scraper conveyor into different stacking bins for immediate use. However, the powder material is prone to accumulate at the discharge ports, resulting in unsmooth material distribution. Moreover, a large number of discharge ports and stacking bins need to be set up to ensure that all the powder material in the scraper conveyor has fallen, which increases the equipment cost and the plant area cost.

Detailed implementation manners

[0019] The technical solutions in the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] As shown in the Figure 2 accompanying drawings, an embodiment of the present invention provides a material distributing device for a scraper conveyor, which includes a horizontal plate 1, a vertical pipe 2 fixedly connected to the horizontal plate 1, and a horizontal pipe 3 fixedly connected to the vertical pipe 2. A central hole 11 is opened in the center of the horizontal plate 1 to communicate the horizontal plate 1 with the vertical pipe 2. A plurality of threaded holes 12 are evenly opened at the edge of the horizontal plate 1. A screw is used to fix the horizontal plate 1 on the scraper conveyor 5. A side hole 21 is opened on the vertical pipe 2 to communicate with the horizontal pipe 3. A filter membrane 22 is covered on the side hole 21. The filter membrane 22 is fixed inside the vertical pipe 2. The horizontal pipe 3 is connected with a blower. The specific working process is as follows: the horizontal plate 1 is respectively fixed at the discharge port 51 of the scraper conveyor 5 by matching bolts with the threaded holes 12. The blower is used to perform negative pressure air extraction on the horizontal pipe 3, so as to form a negative pressure in the scraper conveyor 5 and the vertical pipe 2. The filter membrane 22 blocks the powder material from entering the horizontal pipe 3. When the powder material is conveyed into each storage bin through the scraper conveyor 5, due to the effect of negative pressure, the powder material falls into the corresponding vertical pipe 2 from each discharge port 51 faster, and then falls into the corresponding storage bin through the vertical pipe 2, improving the efficiency of material distribution, reducing the powder amount at the discharge port 51 opened on the scraper conveyor 5, reducing costs. At the same time, a negative pressure is formed in the scraper conveyor 5 and the vertical pipe 2, preventing the powder material from diffusing outwards, reducing pollution, and improving the cleanliness of the working space.

[0021] As shown in the Figure 2 accompanying drawings, for a material distributing device for a scraper conveyor, a vertical plate 4 matching with the vertical pipe 2 is arranged between the vertical pipe 2 and the horizontal pipe 3. A through hole 41 is opened in the center of the vertical plate 4 to communicate with the vertical pipe 2 and the horizontal pipe 3. A plurality of connecting holes 42 are evenly opened at the edge of the vertical plate 4. Threaded blind holes 23 corresponding to the connecting holes 42 are opened on the outer wall of the vertical pipe 2. The vertical plate 4 is fixedly connected with the horizontal pipe 3. Bolts are used to pass through the connecting holes 42 to fix the vertical plate 4 on the vertical pipe 2, which is convenient for replacing the horizontal pipe 3 and convenient for checking whether the filter membrane 22 is ventilated.

[0022] For a material distributing device for a scraper conveyor, the vertical pipe 2 and the horizontal plate 1, and the vertical plate 4 and the horizontal pipe 3 are welded, which is convenient for fixing and reduces costs.

[0023] As shown in the Figure 2 accompanying drawings, for a material distributing device for a scraper conveyor, the diameter of the through hole 41 of the vertical plate 4 is smaller than the inner diameter of the horizontal pipe 3. An arc-shaped support net 24 is arranged in the side hole 21 of the vertical pipe 2. The support net 24 protrudes towards the vertical pipe 2. The support net 24 makes the filter membrane 22 protrude towards the vertical pipe 2, preventing the filter membrane 22 from shrinking in the side hole 21 under the action of wind force and causing blockage of the filter membrane 22, affecting the efficiency of material distribution.

When the powder material hits the filter membrane 22, the support mesh 24 contracts into the side holes 21, and then rebounds towards the vertical pipe 2 under the action of the springs 25, so that the adsorbed powder material on the filter membrane 22 shakes off, preventing the powder material from blocking the filter membrane 22 and affecting the material distribution efficiency.

[0025] As shown in the attached Figure 2 figure, a material distributing device for a scraper conveyor, wherein the vertical pipe 2 is a square pipe, a connecting column 26 is fixedly connected to the inner wall of the vertical pipe 2 connecting the horizontal pipe 3, a sweeping rod 27 is rotatably connected to the connecting column 26, the top end of the sweeping rod 27 protrudes into the scraper conveyor 5, a torsion spring 28 is sleeved on the connecting column 26, one end of the torsion spring 28 is fixed on the inner wall of the vertical pipe 2, the other end of the torsion spring 28 is hooked on the sweeping rod 27, the horizontal pipe 3 is perpendicular to the moving direction of the scraper 52 of the scraper conveyor 5, and the scraper 52 of the scraper conveyor 5 intermittently collides with the sweeping rod 27, driving the sweeping rod 27 to scrape towards the filter membrane 22. When the sweeping rod 27 returns under the action of the torsion spring 28, it scrapes the filter membrane 22 again, cleaning the adsorbed powder material on the filter membrane 22, and further preventing the powder material from blocking the filter membrane 22 and affecting the material distribution efficiency.

[0026] As shown in the attached Figure 2 figure, a material distributing device for a scraper conveyor, wherein a flexible sleeve 271 corresponding to the support mesh 24 is sleeved on the sweeping rod 27, so that during the sweeping process of the sweeping rod 27, the sweeping rod 27 and the support mesh 24 are prevented from wearing the filter membrane 22, and the durability of the filter membrane 22 is improved.

[0027] A material distributing device for a scraper conveyor, wherein the flexible sleeve 271 is made of rubber, which is convenient to manufacture and has a low cost.
