Description

Technical Field

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

[0002] Traditional dust suppression methods mainly include water spraying and misting. While water spraying is simple and direct, it consumes a lot of water and its dust suppression effect is not ideal. Misting captures dust particles in the air by spraying water mist, but traditional misting devices often suffer from uneven spraying, limited coverage, and low dust suppression efficiency.

[0003] To overcome the shortcomings of traditional dust suppression methods, various new dust suppression devices have emerged in recent years. These devices typically use the interaction of high-pressure airflow and water flow to generate fine water droplets or mist, thereby more effectively capturing and fixing dust particles in the air. However, these devices still have some shortcomings in terms of airflow scattering, water flow introduction, airflow reflection, and the design of water outlet devices, resulting in less than ideal dust suppression effects or high maintenance costs. Utility Model Content

[0004] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a dust suppression device that can effectively improve the dust suppression effect.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a dust suppression device, including a cylinder, wherein the end of the cylinder is provided with an opening, and the interior of the cylinder is provided with:

[0006] A high-pressure air duct, wherein the outlet of the high-pressure air duct is located at the center of the cylinder and faces the opening of the cylinder, and a scattering device is provided at the outlet of the high-pressure air duct.

[0007] Multiple water inlets are arranged circumferentially at the opening of the cylinder, and the water inlet direction of the water inlets is towards the center of the cylinder.

[0008] Preferably, an air inlet pipe is fixed inside the cylinder, the air inlet pipe extends into the cylinder and is fixed with a constriction nozzle, one end of the air inlet pipe is connected to a high-pressure water pipe, and the end of the constriction nozzle facing the opening of the cylinder is a pointed tip.

[0009] Preferably, the scattering device includes a connecting frame fixed inside the air inlet pipe, the connecting frame having multiple ventilation slots inside, a connecting rod fixed at the center of the connecting frame, the end of the connecting rod away from the connecting frame extending through the contraction opening of the contraction nozzle to the outside and having a valve core fixed thereon, and a gap being left between the connecting rod and the contraction opening.

[0010] Preferably, the valve core is provided with an annular groove, and a baffle is fixed inside the cylinder. The baffle is provided with a plurality of reflective grooves, which are arranged opposite to the openings of the annular groove.

[0011] Preferably, an annular tube is fixed to the outside of the cylinder, and multiple water inlet nozzles are disposed on the inner wall of the annular tube.

[0012] Preferably, the reflective groove includes multiple annular grooves, and the sides of the annular grooves are inclined surfaces.

[0013] Preferably, a water inlet pipe is connected to the annular pipe, and the water inlet pipe is connected to an external water supply device.

[0014] Preferably, the end of the cylinder is open.

[0015] The beneficial effects of this utility model are as follows:

[0016] The interaction between the airflow generated by the high-pressure duct and the water flow introduced through the inlet rapidly produces a large number of fine water droplets or mist. These droplets or mist have a strong dust-capturing ability, effectively reducing the concentration of dust in the air. The design of the scattering device allows the airflow to be evenly scattered into the cylinder, and the degree and direction of airflow scattering can be changed by adjusting the gap between the connecting rod and the contraction port, thereby achieving precise control of the dust suppression range.

[0017] The annular groove on the valve core works in conjunction with the reflective groove on the baffle to reflect part of the airflow out of the cylinder, increasing the diffusion range and intensity of the airflow and further improving the dust suppression effect. The annular pipe and multiple water inlet nozzles on the outside of the cylinder allow water to be continuously and stably sprayed into the cylinder, working together with the high-pressure airflow to form a finer water mist, enhancing the dust suppression capability of the dust suppression device.

[0024] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0025] Example 1

[0026] like Figures 1-5 As shown in the figure, in this embodiment, a dust suppression device is provided, including a cylinder 1. The end of the cylinder 1 is open. The open design of the cylinder 1 facilitates the introduction and diffusion of airflow and water flow, and at the same time facilitates the observation and adjustment of the working status of the dust suppression device. The inside of the cylinder 1 is provided with a high-pressure air duct and multiple water inlets.

[0027] The outlet of the high-pressure air duct is located at the center of the cylinder 1 and faces the opening of the cylinder 1. A scattering device is provided at the outlet of the high-pressure air duct. The interaction between the airflow generated by the high-pressure air duct and the water flow introduced by the water inlet can generate a large number of fine water droplets or water mist, thereby effectively capturing and fixing dust particles in the air.

[0028] Multiple water inlets are arranged circumferentially at the opening of the cylinder 1, and the water inlet direction is towards the center of the cylinder 1. Water is introduced into the cylinder 1 through the water inlet and meets the diffused airflow.

[0029] Example 2

[0030] like Figures 1-5 As shown, based on Embodiment 1, this embodiment provides the structure of the scattering device, as detailed below:

[0031] An air inlet pipe 2 is fixed inside the cylinder 1. The air inlet pipe 2 extends into the cylinder 1 and is fixed with a constriction nozzle 4. One end of the air inlet pipe 2 is connected to a high-pressure water pipe. The end of the constriction nozzle 4 facing the opening of the cylinder 1 is a pointed tip. The high-pressure water pipe delivers high-pressure water flow into the cylinder 1 through the air inlet pipe 2. When the water flow passes through the constriction nozzle 4, it is accelerated and concentrated and sprayed out to form a high-pressure water column, which works together with the scattered airflow to suppress dust.

[0032] The scattering device includes a connecting frame 3 fixed inside the air inlet pipe 2. Multiple ventilation slots are provided inside the connecting frame 3. A connecting rod 5 is fixed to the center of the connecting frame 3. The end of the connecting rod 5 away from the connecting frame 3 extends through the contraction opening of the contraction nozzle 4 to the outside and is fixed with a valve core 10. A gap is left between the connecting rod 5 and the contraction opening. When the high-pressure airflow passes through the air inlet pipe 2, the airflow pushes the valve core 10 to move, adjusting the gap between the connecting rod 5 and the contraction opening, thereby changing the degree and direction of airflow scattering. The ventilation slots allow the airflow to be scattered more evenly into the cylinder 1.

[0033] The valve core 10 is provided with an annular groove, and a baffle 6 is fixed inside the cylinder 1. The baffle 6 is provided with several reflective grooves. The reflective grooves are arranged opposite to the openings of the annular groove. Some airflow enters the reflective groove through the annular groove and is reflected out of the cylinder 1 by the baffle 6, which increases the diffusion range and intensity of the airflow and improves the dust suppression effect.

[0034] The reflector groove consists of multiple annular grooves with sloping sides. This sloping design allows the reflector groove to better guide airflow, increase the diffusion angle and range of the airflow, and improve dust suppression efficiency.

[0035] Example 3

[0036] like Figures 1-5 As shown, based on Embodiment 1 and Embodiment 2, this embodiment provides an annular water outlet device, specifically as follows:

[0037] An annular pipe 8 is fixed to the outside of the cylinder 1. Multiple water inlet nozzles 9 are set on the inner wall of the annular pipe 8. A water inlet pipe 7 is connected to the annular pipe 8. The water inlet pipe 7 is connected to an external water supply device. The external water supply device provides a stable water flow to the annular pipe 8 through the water inlet pipe 7, ensuring that the water inlet nozzles 9 can continuously spray water and form water mist together with the high-pressure airflow.

[0038] Working principle: When the dust suppression device is activated, the high-pressure air duct begins to operate, generating a high-speed airflow. This airflow is evenly diffused into the cylinder 1 through the connecting frame 3 and ventilation slot in the scattering device. At the same time, the gap between the connecting rod 5 and the contraction port is automatically adjusted according to the airflow pressure, thereby changing the degree and direction of airflow scattering.

[0039] High-pressure water is delivered into the cylinder 1 through the air inlet pipe 2. The water flow is accelerated and concentrated as it passes through the constriction nozzle 4, forming a high-pressure water column. This high-pressure water column encounters and interacts with the scattered airflow, producing a large number of fine water droplets or mist. Part of the airflow enters the reflective groove on the baffle 6 through the annular groove on the valve core 10 and is reflected out of the cylinder 1. This reflection not only increases the diffusion range and intensity of the airflow but also improves the dust suppression efficiency.

[0040] An external water supply device provides a stable water flow to the annular pipe 8 through the inlet pipe 7. Multiple water nozzles 9 on the inner wall of the annular pipe 8 continuously spray water, which, together with the high-pressure airflow, forms a finer water mist. This water mist, together with the scattered airflow and the high-pressure water column, works on the area where dust suppression is needed.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate and not limit the technical solutions of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model without departing from the spirit and scope of this utility model. Any modifications or partial substitutions should be covered within the scope of the claims of this utility model.
