Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of workshop dust removal and environmental protection equipment, and in particular to a dust suppression device for the roof of a scrap steel crushing workshop. Background Technology
[0002] In a scrap steel processing workshop, the raw material consists of piles of scrap steel collected from various places, mixed with various dust, debris, waste paper, waste plastic, etc. When the scrap steel is crushed, a large amount of dust rises in the entire workshop. Especially for processing workshops with large scrap steel volumes, this dust is difficult to dissipate or settle in a relatively short time. If traditional exhaust fans are used for dust removal, the dust removal equipment would have to be designed to be very large due to the long crushing and conveying production line in the workshop. Moreover, the extracted dust would pollute the environment if directly discharged, requiring further treatment, which would significantly increase the cost of dust removal. Therefore, it is necessary to design a relatively simple, inexpensive, and practical dust suppression device. Utility Model Content
[0003] The purpose of this utility model is to address the above-mentioned situation by providing a dust suppression device for the roof of a scrap steel crushing workshop. This dust suppression device, through a novel structural design, can carry out large-scale dust suppression in workshops where dust suppression is required, with good effect, fast speed, and easy control.
[0004] The specific solution of this utility model is as follows: a dust suppression device for the roof of a scrap steel crushing workshop, comprising an auxiliary support installed on the roof of the workshop, on which several dust suppression spray units are installed. All dust suppression spray units are laid along the roof surface of the workshop and are evenly spaced apart. Each dust suppression spray unit includes a water spray pipe, spray nozzles evenly distributed on the water spray pipe, two water supply pipe shafts, a hoisting bracket, and a drive mechanism for driving the water supply pipe shafts to rotate. The two water supply pipe shafts are respectively connected to the two ends of the water spray pipe. One end of the water supply pipe shaft is closed, and the outer end of the other water supply pipe shaft is connected to a high-pressure water supply pipe.

[0020] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0021] See Figures 1-3 This utility model relates to a dust suppression device for the roof of a scrap steel crushing workshop. It includes an auxiliary support 2 installed on the roof 3 of the workshop 1. Further, the auxiliary support is a steel truss structure, welded and installed on the workshop roof. Several dust suppression spray units are installed on the auxiliary support, all laid along the workshop roof surface and evenly spaced. Each dust suppression spray unit includes a water pipe 9, spray nozzles 11 evenly distributed on the water pipe, two water delivery pipe shafts 12, a hoisting bracket 8, and a drive mechanism for the water delivery pipe shafts. Furthermore, the water spray pipe described in this utility model is a hollow metal pipe, which is horizontally mounted on the workshop floor. Two water supply pipe shafts are respectively connected to both ends of the water spray pipe. One water supply pipe shaft is closed at one end, and the outer end of the other water supply pipe shaft is connected to a high-pressure water supply pipe 4. The water supply pipe shafts at both ends of the water spray pipe are hoisted and connected to the auxiliary support through a hoisting bracket. The water supply pipe shafts are rotatably connected to the hoisting bracket. The driving mechanism is connected to one of the water supply pipe shafts. The driving mechanism drives the water supply pipe shaft 12 to rotate, thereby driving the water spray pipe to rotate together.
[0022] Furthermore, the present invention provides a plurality of spray nozzles 11, which are evenly spaced on the pipe wall of the corresponding water spray pipe. Each spray nozzle is shaped like a truncated cone and has a plurality of spray holes 10.
[0023] Furthermore, the water supply pipe shaft described in this utility model is a hollow rotating shaft, which is coaxially arranged with the water spray pipe and is internally connected to the water spray pipe.
[0024] Furthermore, in this embodiment, the driving mechanism includes a drive motor 7, a transmission sprocket 5, and a transmission chain 6. The drive motor is fixedly mounted on the auxiliary bracket, the transmission sprocket is mounted on the corresponding water pipe shaft, and the output shaft end of the drive motor is connected to the transmission sprocket via the transmission chain.
[0025] The water spray pipe in this invention is relatively long and is usually installed horizontally on the roof of the factory building. The entire water spray pipe is controlled to rotate by a drive mechanism. When the workshop is carrying out scrap steel crushing operations, the entire production line occupies a large area and a large amount of dust will fill the entire workshop. At this time, the drive mechanism of this invention can be turned on to drive the entire water spray pipe to rotate. At the same time, each high-pressure water supply pipe is turned on, and the dust-suppressing water is sprayed downward from the air in the form of water mist through the spray nozzles. As a large amount of dust-suppressing water is sprayed out in the form of water mist, a large amount of dust in the workshop will fall to the ground with the water mist, which plays a role in dust suppression. Moreover, the effect is very significant and the cost of dust suppression treatment is very low.
[0026] Since the dust suppression spray units in this invention are distributed throughout the workshop and located at the top, when dust suppression operations need to be started in a certain area, only the dust suppression spray units in certain areas can be activated to spray downwards, while other areas can be stopped to allow for localized dust suppression.
[0027] The dust suppression facility of this invention can achieve large-scale dust suppression in the entire workshop with rapid and obvious results. This method has a good dust suppression effect in situations where there is a lot of floating dust in some workshops and the production equipment that generates floating dust is large and difficult to handle centrally.
[0028] Each dust suppression spray unit in this invention is controlled by an individual drive motor, allowing for both localized and centralized dust suppression operations, offering high flexibility. This invention is installed as a single unit on the roof or in mid-air of a workshop or factory building, occupying minimal ground space and not affecting ground-based production.
