Description

Technical Field

[0001] The utility model relates to the technical field of atomization dust removal, in particular to an atomization dust removal device for an underground mine ventilation system. Background Art

[0002] The ventilation system in the mine is one of the key equipment to ensure the safe production of the mine. However, during the operation of the ventilation system, due to the special environment in the mine, a large amount of dust and powder will be generated. These dust and powder not only threaten the health of miners, but also may cause various safety accidents. Therefore, how to effectively remove dust from the underground ventilation system of the mine has always been an important issue in the safe production of the mine. At present, the common dust removal methods for the underground ventilation system of the mine mainly include mechanical dust removal, wet dust removal and electrostatic dust removal. However, these methods have some problems in practical application, such as low dust removal efficiency, unstable dust removal effect, and difficult equipment maintenance. Therefore, it is necessary to develop a new type of dust removal device for the underground ventilation system of the mine.

[0003] After searching, the Chinese utility model patent with announcement number "CN204327168U" discloses "a kind of atomizing dust removal device for underground mine ventilation system". This application uses the principle of centrifugal force to transmit tap water through the core rod to the spiral water chamber and spray it out through the atomizing nozzle. The characteristics of the underground ventilation airflow are used to force the atomized water droplets to split into a film, and the adsorptive dust settles under the action of gravity, thereby achieving the purpose of dust removal and dust reduction. It has the advantages of simple structure, easy installation and high dust removal efficiency.

[0004] However, the above-mentioned device and similar devices are unable to remove most of the moisture in the dust removal process during actual use, which will lead to increased humidity in the mine, and have an adverse effect on the health of miners and the normal operation of equipment. Utility Model Content

[0005] The utility model aims to provide an atomizing dust removal device for an underground mine ventilation system to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an atomizing dust removal device for an underground mine ventilation system, comprising:

[0007] Spray assembly, guide assembly and filter sleeve;

[0008] The filter sleeve is installed between the spray assembly and the guide assembly in a detachable form. The spray assembly is installed at the discharge port of the underground mine ventilation system and is used for spraying the airflow in the underground mine ventilation system.

[0009] During the operation of the spray assembly, the guide assembly allows the airflow with dust attached to move toward the two sides outside the filter sleeve. Under the operation of the spray assembly, the airflow with dust attached allows part of the moisture to be discharged from the pores of the filter sleeve.

[0010] Furthermore, the spray assembly comprises:

[0011] A connecting sleeve seat is used to be installed at the discharge port of the underground ventilation system of a mine, and a notch for receiving the filter sleeve is provided around the bottom of the connecting sleeve seat;

[0012] Communication ports are respectively provided on both sides of the connection sleeve;

[0013] Micro-atomizers are fixed on both sides of the outside of the connecting sleeve respectively, and the spray end of the micro-atomizer is extended to the inside of the connecting sleeve by means of the connecting port.

[0014] Furthermore, the flow guide assembly includes:

[0015] A carrying sleeve adapted to the connecting sleeve, wherein the top of the carrying sleeve is provided with openings for receiving the filter sleeve on four sides thereof;

[0016] The mounting sleeve has assembly openings on both sides thereof;

[0017] Fans are fixed on both sides of the outside of the carrying sleeve respectively, and the air outlet end of the fan is extended to the inside of the connecting sleeve by means of the assembly opening.

[0018] Furthermore, the air outlet end of the fan is a connecting pipe, the connecting pipe and the assembly port are adapted, a guide cover is fixed to one end of the connecting pipe, the guide cover and the connecting pipe are connected, and the cover port of the guide cover is inclined to face one side of the inside of the filter sleeve.

[0019] Furthermore, hooks are fixed to both sides of the inner wall of the connecting sleeve and both sides of the inner wall of the carrying sleeve respectively;

[0020] Hanging rings are fixed on both sides of the top end and the bottom end of the filter sleeve, and the hanging rings are matched with the hooks.

[0021] Furthermore, force handles are fixed to both sides of the top and bottom ends of the outside of the filter sleeve, respectively, and the force handles are used to artificially establish an adaptive relationship between the hanging ring and the hook.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] The atomizing dust removal device for the underground mine ventilation system, through the cooperation of the spray assembly and the guide assembly, atomizes and guides the dust in the underground mine ventilation system, and then filters out the dust and excess moisture through the filtering effect of the filter sleeve, thereby realizing effective dust removal for the underground mine ventilation system. At the same time, the device has a simple structure and is easy to operate, and can effectively improve the air quality underground in the mine and protect the health of workers.

[0024] In addition, in the specific implementation of the device proposed in the present application, the spray assembly generates water mist through a micro-atomizer, and the water mist is mixed with the air flow in the underground mine ventilation system, so that the dust particles are attached to the water mist to form larger particles, which is convenient for subsequent filtering and processing. At the same time, the design of the spray assembly allows part of the water to be discharged from the pores of the filter sleeve, thereby avoiding the influence of the water on the underground mine ventilation system;

[0025] In addition, when the present application is actually used, the guide assembly guides the airflow with dust attached to the outer sides of the filter sleeve through the airflow generated by the fan, so that the dust particles hit the surface of the filter sleeve under the action of inertia, thereby achieving dust filtering. At the same time, the design of the guide cover makes the airflow more concentrated, increases the probability of dust particles contacting the filter sleeve, and further improves the dust removal effect;

[0026] Finally, the device provided by the present application also realizes the rapid installation and removal of the filter sleeve through the cooperation of the hook and the hanging ring, which facilitates the cleaning and replacement of the filter sleeve. At the same time, the design of the force-bearing handle makes manual operation more convenient and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The airflow with dust attached allows part of the moisture to be discharged from the pores of the filter sleeve 1 under the operation of the spray assembly 2.

[0033] It should be noted that the reference Figure 2 It can be seen that in the present application, the spray assembly 2 includes a connecting sleeve 201, and bolt assembly openings 207 are respectively opened on the four sides of the interior of the connecting sleeve 201. By installing bolts in the bolt assembly openings 207, the assembly connection with the discharge port of the underground ventilation system of the mine is completed.
