Technical Field

[0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to an environmental protection equipment used for dust removal in mines. Background Art

[0002] During mining, long-term operation will cause dust, which will increase the amount of dust particles suspended in the air. The existing dust removal method mainly uses spraying to reduce the content of dust particles suspended in the air during the operation to achieve the effect of dust removal.

[0003] For example, China's invention CN118745929A is an environmentally friendly dust reduction device for mines. It uses a defogger consisting of a blade group with adjustable angles. It can not only act as a guide blade in spray mode to reduce turbulence and improve spray efficiency, but also be transformed into a defogger blade in dust suction mode. By increasing the collision chance between droplets and dust, the dust capture efficiency is improved.

[0004] However, in the prior art, components such as the motor and blades in the dust removal device are located inside the main cylinder section, thereby occupying the internal space of the cylinder, which not only makes the volume of the cylinder larger, but also blocks the flow of internal airflow, resulting in lower overall air outlet efficiency. Summary of the invention

[0005] The purpose of the present invention is to provide an environmental protection device for dust removal in mines. The ventilation pipe is rotatably connected to the fixed pipe in the air supply cylinder. The inner wall of the ventilation pipe is provided with blades in a circular array. The ventilation pipe is driven to rotate by a driving mechanism on the outside of the air supply cylinder. The airflow is driven by the blades, thereby solving the problem that the existing components occupy the internal space, resulting in a large volume of the cylinder and low air outlet efficiency.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0010] As a preferred technical solution of the present invention, a fixing plate is fixedly connected to the inner wall of the air supply duct, the fixing plate is provided with through holes corresponding to the ventilation pipes one by one, and the ventilation pipes are fixedly connected to one side of the fixing plate close to the air outlet end of the air supply duct.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figures 1 to 3 As shown, the present invention is an environmental protection device for dust removal in mines, comprising an air supply tube 1 , wherein a spray assembly 101 is provided at the air outlet end of the air supply tube 1 for generating water mist at the air outlet end of the air supply tube 1 .

[0036] like Figures 4 to 7 As shown, the inner wall of the air supply tube 1 is fixedly connected with a plurality of fixed tubes 102. For example, as shown in the figure, there are five fixed tubes 102. The fixed tubes 102 are all rotatably connected with ventilation tubes 2, and the inner wall of the ventilation tube 2 is provided with blades 201 in a circumferential array. The outer side of the air supply tube 1 is connected with a driving mechanism, and the driving mechanism is in transmission connection with the ventilation tube 2, so as to drive the five ventilation tubes 2 to rotate synchronously, and the blades 201 are used to drive the airflow.

[0037] Specifically, Figure 8 and 9 As shown, the outer wall of the ventilation pipe 2 is fixedly connected with a gear ring 202, and the driving mechanism includes a rotating ring 3 rotatably connected to the outer wall of the air supply cylinder 1. The outer wall of the rotating ring 3 is fixedly connected with an outer gear ring 301, the inner wall of the rotating ring 3 is fixedly connected with an inner gear ring 302, and the inner gear ring 302 is meshed with the gear ring 202, and the outer wall of the rotating ring 3 is fixedly connected with a driving motor 303, and the driving motor 303 is connected with a transmission gear 304 meshed with the outer gear ring 301.

[0038] Among them, the five fixed tubes 102 include a fixed tube 102 coaxially arranged with the air supply tube 1, and the other ten fixed tubes 102 are arranged in a circular array around it, so that the ventilation tube 2 located at the center position and the other four ventilation tubes 2 are meshed with each other through the gear ring 202.

[0039] The inner gear ring 302 meshes with the gear rings 202 of the four ventilation pipes 2 located on the outside, the driving motor 303 drives the rotating ring 3 to rotate through the transmission gear 304, the rotating ring 3 drives the four ventilation pipes 2 on the outside to rotate through the inner gear ring 302, and the four ventilation pipes 2 drive the ventilation pipe 2 located at the center to rotate through the meshing gear rings 202, so that the five ventilation pipes 2 rotate synchronously.

[0040] The ventilation pipe 2 rotates, so that the internal blades 201 drive the airflow, and the airflow flows through the ventilation pipe 2 and is blown out from the air outlet of the air supply tube 1, thereby driving the water mist to achieve dust removal. The airflow is driven by the blades 201, and the drive mechanism is arranged on the outside, and the blades 201 are arranged on the inner wall of the ventilation pipe 2 to form a shaftless structure, thereby effectively reducing the occupation of the internal space of the air supply tube 1. Under the condition of the same air output, the volume of the air supply tube 1 is smaller, and the obstruction of the internal airflow by the components is reduced, which is conducive to improving the overall air output efficiency.

[0041] As a preferred example, Figure 4 and 5 As shown, a fixing plate 103 is fixedly connected to the inner wall of the air supply cylinder 1, and the fixing plate 103 is provided with through holes corresponding to the ventilation pipes 2 one by one, and the ventilation pipes 2 are fixedly connected to the fixing plate 103 on the side close to the air outlet end of the air supply cylinder 1. In addition, the fixing plate 103 is a spherical curved structure, and the fixing plate 103 protrudes toward the air outlet end of the air supply cylinder 1, so that the fixing plate 103 plays a role in guiding the airflow entering the air supply cylinder 1, so that the airflow entering the air supply cylinder 1 flows through the ventilation pipes 2, thereby avoiding the formation of turbulence in the air flow and affecting the airflow passing efficiency.

[0042] As another preferred embodiment, Figure 4 and 6 As shown, the air supply tube 1 includes an air outlet section 11, an air generation section 12 and an air inlet section 13, and the fixed pipe 102 and the driving mechanism are both connected to the air generation section 12. The air outlet end of the air outlet section 11 is a constricted structure, so that the air flow velocity at the outlet end is increased, thereby improving the diffusion effect of the water mist.

[0043] The air outlet section 11 is connected to the air generating section 12 via a flange, and the air outlet section 11 is located outside the rotating ring 3 and is provided with an escape opening corresponding to the transmission gear 304 , so that the air outlet section 11 plays a protective role on the rotating ring 3 and the ventilation pipe 2 .

[0044] In addition, one end of the air inlet section 13 is sleeved inside the air generation section 12, and two to four studs 104 are fixedly connected to the outer wall of the air inlet section 13. The side wall of the air generation section 12 is provided with slots 105 corresponding to the studs 104 one by one. The studs 104 are matched with nuts. The nuts are locked to fix the position between the air inlet section 13 and the air generation section 12. The slots 105 are provided along the axial direction of the air generation section 12, thereby facilitating the axial movement of the air inlet section 13 to achieve installation and disassembly.

[0045] In addition, a stainless steel mesh 106 is installed on the inner wall of the air inlet section 13, and the stainless steel mesh 106 can block leaves or other larger foreign objects to prevent them from entering the ventilation pipe 2 and causing blockage, thereby helping to improve the reliability of use.

[0046] At the same time, since the center of the air supply tube 1 is located at the air generation section 12, the bracket for installing the air supply tube 1 can be connected to the air generation section 12, such as by a rotation connection, so as to facilitate the adjustment of the pitch angle of the air supply tube 1 and improve the overall practicality.
