The dust removal equipment is usually placed on the partition wall between adjacent material storage areas.
[0003] Currently, the number of nozzles in traditional water spraying dust suppression equipment is fixed, resulting in a limited spraying range. When a large amount of dust is generated in the unloading area of the silo, it often cannot be effectively covered, and the dust suppression effect is not ideal.

[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0035] This embodiment aims to provide a water spraying and dust removal device for a concrete mixing plant. Its main function is to adjust the lateral displacement distance of the water spraying pipe and the spray elevation angle, thereby expanding the spraying range and achieving efficient dust removal.
[0036] Reference Figures 1-4 It includes: a base 1 and a sprinkler pipe. The base 1 is placed horizontally on the top of the silo partition wall, and the length direction of the base 1 is consistent with the length direction of the silo partition wall. The base 1 is U-shaped, and the U-shaped opening of the base 1 fits into the silo partition wall so that the U-shaped opening of the base 1 is placed on the silo partition wall with the U-shaped opening facing down. T-shaped slide rails 6 are welded to both sides of the top of the base 1 along its length direction. The two slide rails 6 are symmetrical and parallel to each other.
[0037] The base 1 has supports on both sides of its top. The two supports can slide synchronously along the length of the base 1, and the two supports move in opposite directions.
[0038] Specifically, the support consists of a horizontal support rod 7 and a pair of vertical support rods 8. The two vertical support rods 8 are welded and fixed to the bottom of both ends of the horizontal support rod 7. The lower end of the vertical support rod 8 is provided with a hook groove that matches the shape of the slide rail 6, so that the lower end of the vertical support rod 8 can be hooked onto the top of the slide rail 6, thereby allowing the support to slide along the slide rail 6 in a directional manner.
[0039] A gear 9 is horizontally positioned between the two supports and centered thereon. A motor 11 is erected below the gear 9. The bottom of the motor 11 can be fixed to the top of the base 1 by bolts. The rotating shaft of the motor 11 is fixedly connected to the center of the gear 9 to drive the gear 9 to rotate in both directions. The motor 11 can be a three-phase asynchronous motor, and the forward and reverse rotation can be switched manually or automatically through an external control device (such as a contactor or electronic controller). This is an existing mature technology and will not be elaborated further. The cross braces 7 of the two supports are welded with teeth on their corresponding sides and mesh with the gear 9. The teeth are distributed along the length of the cross braces 7 so that the rotation of the gear 9 drives the two supports to move horizontally in opposite directions synchronously. At both ends of the cross braces 7, baffles 10 are welded horizontally and vertically to prevent the gear 9 from slipping off the teeth.
[0040] The sprinkler pipe includes a shaft pipe 2 and a bend pipe 3. The cross brace 7 is hollow, so that the shaft pipe 2 can be coaxially rotated and fitted inside the cross brace 7, and the two ends of the shaft pipe 2 protrude outward to connect to the two ends of the bend pipe 3 respectively. The shaft pipe 2 and the bend pipe 3 are interconnected and are fan-shaped as a whole. Spray heads 5 protrude from the surface of the bend pipe 3 towards the hopper area. Several spray heads 5 are distributed at intervals along the extension direction of the bend pipe 3. The arrangement of spray heads 5 according to the extension direction of the bend pipe 3 can greatly expand the spraying range. The water inlet end of the shaft pipe 2 is connected to a flexible pump pipe 4. Based on the rotatable condition of the shaft pipe 2, the bend pipe 3 can swing up and down to adjust the elevation angle of the spray heads 5 to change the spraying position and ensure effective dust removal.
[0041] Specifically, a support plate 12 is horizontally welded and fixed between the two vertical support rods 8 of the bracket. The support plate 12 is located above the base 1. A telescopic arm is obliquely provided between the support plate 12 and the bend 3 on the same side. The high end of the telescopic arm is rotatably fitted onto the outside of the center of the bend 3, and the low end of the telescopic arm is hinged to the center of the upper surface of the support plate 12 so that its high end can swing up and down. The telescopic arm is composed of a long sleeve 13, a short sleeve 14, and a threaded rod 15. One end of the long sleeve 13 is fitted onto the outside of the middle of the bend 3 and does not restrict the bend. The pipe 3 rotates, and the other end is threaded onto the outside of one end of the threaded rod 15. One end of the short sleeve 14 is hinged to the center of the upper surface of the support plate 12, and the other end is threaded onto the outside of the other end of the threaded rod 15. A handle is welded radially in the middle of the threaded rod 15 so that the worker can rotate the threaded rod 15 to adjust the distance between the long sleeve 13 and the short sleeve 14, thereby adjusting the length of the telescopic arm. By extending or shortening the telescopic arm, the upward angle of the bend pipe 3 can be changed, thereby expanding or reducing the spraying range of the spray head 5 on the bend pipe 3.
[0042] During use, first adjust the angle of the bend 3 according to the actual dust emission location to initially adjust the spraying range, ensuring that the spray head 5 can spray water to the dust area. Then, control the gear 9 to rotate forward and backward through the motor 11 to make the bracket move horizontally along the track repeatedly, thereby spraying a large area of dust and ensuring that the water sprayed from the spray head 5 can effectively remove dust.
[0043] The water spraying dust removal device provided in this embodiment can expand the spraying range by changing the lateral displacement distance of the water spray pipe, ensuring that dust can be covered over a large area. It can also accurately spray dust areas by changing the elevation angle of the water spray pipe, thereby achieving efficient dust removal.
[0044] It is understood that the above description is merely exemplary and the embodiments of this application do not limit the scope of the application.
[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
