[0002] During the process of unloading coal by the car tipper, a large amount of coal dust is generated. On the one hand, it affects the operation of other equipment in the workshop. For example, the photoelectric sensor in the operation of the car tipper is affected by the dust, delaying the tipping.

DETAILED DESCRIPTION

[0054] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] As described in the background technology, a large amount of dust is generated during the unloading process of the dumper, which pollutes the workshop and equipment, affecting the safety, reliability and service life of the equipment. Therefore, how to reduce the dust generated during the unloading process of the dumper, improve the cleanliness of the workshop and the safety and reliability of the equipment operation, and extend the service life of the equipment has become a technical problem that technicians in this field need to solve urgently.

[0056] To solve the above problems, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The present invention provides a spray dust removal device for a car dumper, comprising: a side wall 1 and a first spray mechanism 3, a second spray mechanism 4, a mounting mechanism 5 and a rotating mechanism 6 mounted on the side wall 1. The side wall 1 is vertically arranged and located on one side of the car dumper 2. The car dumper 2 turns clockwise to unload coal. When the car dumper 2 turns 90°, the coal discharge direction of the car dumper 2 faces the side wall 1. The second spray mechanism 4 is located at the lower part of the first spray mechanism 3. The mounting mechanism 5 rotates and mounts the second spray mechanism 4 on the side wall 1. The rotating mechanism 6 can drive the second spray mechanism 4 to rotate. The first spray mechanism 3 and the second spray mechanism 4 spray to remove dust generated by the car dumper 2 turning and unloading coal.

[0057] In specific implementation, the coal-carrying train passes through the workshop, and the first carriage drives to the dumper 2. After the dumper 2 dumps the raw coal in the first carriage, the coal-carrying train continues to move forward, and the second carriage drives to the dumper 2. The dumper 2 dumps the raw coal in the second carriage, and repeats this process. The dumper 2 unloads coal from each carriage in turn. Each carriage carries about 65-70 tons of raw coal. The natural stacking density of coal with a low moisture content is 0.7-1t / m3. There is air inside the raw coal in the carriage, which is large in volume and loosely stacked. Figure 1 As shown, when the dumper 2 dumps the raw coal in the carriage, a large amount of raw coal is dumped onto the vibrating coal grate 104, passes through the coal grate 104 and falls into the coal hopper at the bottom of the coal grate 104, and a large amount of dust is generated in this process: on the one hand, due to the small stacking density of the raw coal, before the raw coal falls to the bottom, some fine particles break away from the trend of the main body of the raw coal falling during the movement, and are drawn into the internal environment of the workshop by the flowing air, forming upper dust 105; on the other hand, in the process of a large volume of raw coal falling, the air at the bottom of the dumper 2 is squeezed, the bottom pressure rises, and the air moves from the bottom of the coal hopper to the upper part of the workshop. In the process of the carriage turning over, the falling of the raw coal is affected by gravity, and the gaps between the particles increase sharply. The buoyancy and gravity ratio of the fine coal powder particles themselves is large, Fbuoyancy / Fweight≈1, and the falling speed is less than that of the large pieces of raw coal. At the same time, in the process of unloading and falling of the coal, a large amount of air at the bottom moves upward under the influence of pressure, entraining the fine particles, further leading to the formation of dust 105.

[0058] The spray dust removal device for a car tipper provided by the present invention is provided with a first spray mechanism 3 to spray and eliminate the upper dust generated by the car tipper 2 when unloading coal. A second spray mechanism 4 is provided, and the second spray mechanism 4 is fixed to the side wall 1 through a mounting mechanism 5. The second spray mechanism 4 is driven to rotate through a rotating mechanism 6 to adjust the spray angle. According to the source of the dust 105 generated by the different flipping angles of the car tipper 2, the spray angle of the second spray mechanism 4 is adjusted to eliminate the dust from the source, thereby reducing the dust generated during the flipping and unloading process of the car tipper, improving the cleanliness of the workshop and the safety and reliability of the equipment operation, and extending the service life of the equipment.

The number of the second bracket 53 and the second bearing 54 are both 2, respectively located at the two ends of the second mother tube 41, and by providing the second bracket 53 and the second bearing 54, the stability and reliability of the rotational connection between the second mother tube 41 and the side wall 1 are further improved.

By setting the third bracket 61 and the telescopic motor 62, the spray angle of the second nozzle 42 can be adjusted by rotating the second mother tube 41, and then the spray angle of the second nozzle 42 is adjusted according to the source of the dust 105 generated during the flipping and unloading of coal, and the dust 105 is eliminated from the source.

The first guide portion 103 is a U-shaped opening, and the U-shaped opening is continuously enlarged in the direction close to the slider 96. The first guide portion 103 has the same structure as the second guide portion.

[0066] During specific implementation, the lifting and flipping mechanism 9 is vertically installed on the side wall 1, the first limit piece 101 is located at the upper part, the second limit piece 102 is located at the lower part, the end of the rotating shaft 97 is connected to the first mother tube 31, and the slider 96 is connected to the motor.
