Description

Technical Field

[0001] This utility model relates to the technical field of dust suppression devices, specifically a limestone crushing dust suppression device. Background Technology

[0002] In the limestone crushing process, crushing equipment is typically used inside a crushing plant to crush the limestone. To reduce dust pollution generated during crushing, the conventional dust suppression method is to install multiple spray nozzles in an array on the plant and connect these nozzles to a water source for dust suppression.

[0003] However, this conventional dust suppression method has obvious drawbacks: the dust generated by the crushing device when crushing limestone will first escape into the space of the plant in large quantities, and then the spray head will treat the dust in the space for dust suppression, resulting in low dust suppression efficiency and a lot of dust remaining in the plant, which affects the working environment and the health of the operators. Utility Model Content

[0004] The present invention provides a limestone crushing and dust suppression device to solve the problem of low dust suppression efficiency in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A limestone crushing and dust suppression device includes a crushing mechanism. Both the inlet and outlet ends of the crushing mechanism are equipped with material channels. Multiple sets of cross-sectional spray mechanisms are arranged from top to bottom on the material channels. The outer end of each set of cross-sectional spray mechanisms is connected to a guide pipe, which in turn connects to an external water supply system. The external water supply system can utilize existing technology and include a water source device, such as a water tank, reservoir, or direct connection to tap water; water conveying equipment, such as a water pump and water pipeline, with the water pipeline connected to the guide pipe; and may also include filtration equipment, such as a filter, to prevent impurities such as mud, sand, and rust from clogging the spray nozzles. Specifically, controllable valves, such as ball valves and gate valves, can be installed on the water pipeline for switching the pipeline on and off, and pressure regulating valves for adjusting water pressure and stabilizing the atomization effect. "Multiple sets" refers to at least two sets. The crushing mechanism can utilize existing technology, as long as it can achieve vertical crushing of the material. During operation, limestone enters the crushing mechanism through the feed chute at the inlet. During this process, multiple sets of cross-sectional spray mechanisms are activated. An external water supply system delivers water to the cross-sectional spray mechanisms via a guide pipe, causing the spray nozzles to spray water mist onto the material in the feed chute. The water mist fully contacts the material surface and any raised dust, adsorbing and settling the dust. The crushed material is then discharged from the outlet chute, where it undergoes another dust suppression treatment at the cross-sectional spray mechanism. This structure effectively reduces dust generation and diffusion during the material transport process before and after limestone crushing, thanks to the all-around dust suppression achieved by multiple sets of cross-sectional spray mechanisms. This significantly improves the working environment, reduces the health hazards of dust to workers, and minimizes dust pollution to the surrounding environment.

[0007] Furthermore, the material channel includes a mounting bracket and fixed ring seats detachably connected to the upper and lower ends of the mounting bracket. The inner end of the upper fixed ring seat is detachably connected to a limiting discharge channel. At least one set of the cross-sectional spray mechanism is disposed on the upper fixed ring seat, and at least one set of the cross-sectional spray mechanism is disposed on the lower fixed ring seat. A rubber dust cover is detachably connected between the upper and lower fixed ring seats. The material channel at the feed end and the material channel at the discharge end have the same structure, differing only in size, thus achieving compatibility between the feed end and the discharge end. The lower fixed ring seat in the material channel on the feed end side is detachably connected to the feed port of the crushing mechanism, and the upper fixed ring seat in the material channel on the discharge end side is detachably connected to the discharge port of the crushing mechanism. The detachable connection can be any of the existing technologies, such as bolt connection. The mounting bracket can be detachably connected to the fixing ring seats at both ends using any existing detachable connection method. For example, the fixing ring seats may have connecting seats, and the mounting bracket can be inserted into the groove of the connecting seat, or the connecting seat can be inserted into the end groove of the mounting bracket, and then the two can be connected by bolts. The rubber dust cover can also be detachably connected to the fixing ring seats using any existing method. For example, a positioning rod can be set on the outside of the fixing ring seat, and a positioning hole can be set on the rubber dust cover through which the positioning rod passes, and then a limiting block can be threaded onto the positioning rod. In use, the mounting bracket provides stable support for the entire material channel, limits the material falling direction and range in the material discharge channel, and allows the material to smoothly enter the crushing mechanism and be discharged from the crushing mechanism. The fixing ring seats at the upper and lower ends facilitate the installation of the cross-sectional spraying mechanism. The rubber dust cover acts as a seal between the fixing ring seats, preventing dust from leaking from the connection of the fixing ring seats. At the same time, if maintenance or replacement of components such as the spraying mechanism is required, the fixing ring seats can be removed for easy operation. This detachable and modular material channel facilitates equipment installation, commissioning, maintenance, and component replacement, reducing maintenance costs and complexity. The rubber dust cover ensures the sealing of the material channel, reducing dust leakage and improving dust suppression. The limiting material feeding channel ensures the direction and range of material conveying, preventing material from colliding with the fixed ring seat at the lower end.

[0008] Furthermore, the cross-sectional spray mechanism includes multiple spray heads and anti-collision rings. A through hole for inserting the spray head is provided on the fixing ring seat. The anti-collision ring is detachably connected to the inner side of the fixing ring seat above the through hole. The guide pipe is connected to the outer water inlet of the spray head. The spray head can be configured according to the atomization principle as follows: a high-pressure atomizing nozzle, which relies on water pressure to break up the droplets, producing fine droplets, suitable for high-concentration dust; or a low-pressure atomizing nozzle, which relies on airflow assistance, producing slightly larger droplets, suitable for large-area dust suppression. The nozzle and external water supply system can be connected via the guide pipe. The guide pipe can be connected to the water inlet of the spray head using any existing pipe connection method. This application uses the same connection method as existing spray heads. During use, the spray head atomizes and sprays out the water delivered by the guide pipe to achieve dust suppression; the anti-collision ring is set above the through hole to prevent the spray head from colliding with the material during the material conveying process and to avoid damage to the spray head due to collision; at the same time, the guide pipe is connected to the water inlet at the outer end of the spray head to ensure stable water delivery.

[0009] Furthermore, an annular groove is provided within the through hole, and a sealing ring that fits into the outer wall of the spray head is disposed within the annular groove. This structure improves the sealing performance of the spray head installation, ensuring the spray pressure and atomization effect of the spray head, preventing dust overflow, and thus guaranteeing the dust suppression performance of the dust suppression device.

[0010] Furthermore, the spray head is equipped with a wing plate, which is detachably connected to the fixing ring seat via connecting bolts. With this structure, the spray head is threadedly connected to the bolt holes on the fixing ring seat via connecting bolts on the wing plate, making the connection and fixing method simple and convenient.

[0011] Beneficial effects: By setting up material channels with multiple sets of cross-sectional spray mechanisms at the feed and discharge ends of the crushing mechanism, the limestone is first subjected to dust suppression before entering the crushing mechanism, and the dust generated during crushing is suppressed again when it overflows. The multiple sets of cross-sectional spray mechanisms form multiple dust suppression paths, which greatly improves the dust suppression efficiency and reduces the impact of dust on the working environment and operators.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a limestone crushing dust suppression device according to this embodiment includes a crushing mechanism 1. Both the inlet and outlet ends of the crushing mechanism 1 are provided with material channels 2. Multiple sets of cross-sectional spraying mechanisms 3 are arranged from top to bottom on the material channels 2. The outer end of each set of cross-sectional spraying mechanisms 3 is connected to a guide pipe and is connected to an external water supply system through the guide pipe. The material channel 2 includes a mounting bracket 201 and fixed ring seats 202 detachably connected to the upper and lower ends of the mounting bracket 201. The inner end of the upper fixed ring seat 202 is detachably connected to a limiting discharge channel 203. At least one set of cross-sectional spraying mechanisms 3 is disposed on the upper fixed ring seat 202, and at least one set of cross-sectional spraying mechanisms 3 is disposed on the lower fixed ring seat 202. A rubber dust cover 204 is detachably connected between the upper and lower fixed ring seats 202. The cross-sectional spray mechanism 3 includes multiple spray heads 301 and anti-collision rings 302. A through hole for inserting the spray head 301 is provided on the fixed ring seat 202. The anti-collision ring 302 is detachably connected to the inner side of the fixed ring seat 202 above the through hole. The guide pipe communicates with the outer end inlet of the spray head 301. An annular groove is provided in the through hole, and a sealing ring 4 that fits the outer wall of the spray head 301 is provided in the annular groove. A wing plate 303 is provided on the spray head 301, and the wing plate 303 is detachably connected to the fixed ring seat 202 by connecting bolts 304. In operation, limestone material enters the crushing mechanism 1 through the feed channel 2 at the feed end. It first passes through the cross-sectional spray mechanism 3 at the feed end. The cross-sectional spray mechanism 3 sprays water mist from the spray head 301 to suppress dust on the surface of the limestone. The limestone then enters the crushing mechanism 1 for crushing. During the crushing process, dust generated overflows from the feed and discharge ends of the crushing mechanism 1 and is again suppressed by the cross-sectional spray mechanisms 3 at both ends. Each section of the feed channel 2 is equipped with multiple sets of cross-sectional spray mechanisms 3, forming multiple dust suppression paths, effectively improving dust suppression efficiency. This structure, by setting up feed channels 2 with multiple sets of cross-sectional spray mechanisms 3 at the feed and discharge ends of the crushing mechanism 1, ensures that the limestone undergoes dust suppression before entering the crushing mechanism 1, and the dust generated during crushing is suppressed again upon overflow. The multiple sets of cross-sectional spray mechanisms 3 form multiple dust suppression paths, greatly improving dust suppression efficiency and reducing the impact of dust on the working environment and operators.
