Abstract
Description
Technical Field
[0001] This invention belongs to the field of environmental protection equipment technology, and in particular relates to an environmental protection device for dust removal in mines. Background Technology
[0002] During mining operations, prolonged work generates dust, causing a continuous increase in airborne dust particles. Current dust control methods primarily rely on spraying to reduce the amount of airborne dust particles generated during operations, thus achieving a dust removal effect.
[0003] For example, Chinese invention CN118745929A describes an environmentally friendly dust removal device for mines. It uses a demisting device composed of adjustable-angle blades. In spray mode, it can not only act as a guide blade to reduce turbulence and improve spray efficiency, but also transform into a demisting blade in dust suction mode. By increasing the collision opportunities between droplets and dust, it can improve dust collection efficiency.
[0004] However, in existing dust removal devices, components such as motors and blades are located inside the main cylinder section, which occupies the internal space of the cylinder. This not only makes the cylinder larger but also obstructs the flow of internal airflow, resulting in low overall air output efficiency. Summary of the Invention
[0005] The purpose of this invention is to provide an environmental protection device for dust removal in mines. The device is connected to a ventilation pipe by a fixed pipe inside the air supply duct. The ventilation pipe has blades arranged in a circular array on its inner wall. The ventilation pipe is driven to rotate by a drive mechanism on the outside of the air supply duct. The airflow is driven by the blades. This invention solves the problems of existing components occupying internal space, resulting in a large volume of the duct and low air output efficiency.
[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:
[0007] This invention relates to an environmental protection device for dust removal in mines, comprising an air supply duct, a spray assembly at the air outlet of the air supply duct, a plurality of fixed pipes fixedly connected to the inner wall of the air supply duct, and ventilation pipes rotatably connected to the fixed pipes. Blades are arranged in a circular array on the inner wall of the ventilation pipes. A drive mechanism is connected to the outer side of the air supply duct and is connected to the ventilation pipes in a transmission connection, for driving the plurality of ventilation pipes to rotate synchronously, and using the blades to drive the airflow.
[0008] As a preferred embodiment of the present invention, a gear ring is fixedly connected to the outer wall of the ventilation duct, and the driving mechanism includes a rotating ring rotatably connected to the outer wall of the air supply duct; an outer gear ring is fixedly connected to the outer wall of the rotating ring, and an inner gear ring is fixedly connected to the inner wall of the rotating ring, and the inner gear ring meshes with the gear ring; a drive motor is fixedly connected to the outer wall of the rotating ring, and the drive motor is connected to a transmission gear that meshes with the outer gear ring.
[0009] As a preferred embodiment of the present invention, the plurality of fixed pipes include a fixed pipe coaxially arranged with the air supply duct, and the remaining fixed pipes are arranged in an array around its circumference, so that the ventilation pipe located at the center position and the remaining ventilation pipes are engaged with each other by a toothed ring.
[0010] As a preferred embodiment of the present invention, a fixing plate is fixedly connected to the inner wall of the air supply duct. The fixing plate has through holes that correspond one-to-one with the ventilation pipes, and the ventilation pipes are fixedly connected to the side of the fixing plate near the air outlet end of the air supply duct.
[0011] As a preferred embodiment of the present invention, the fixing plate has a spherical curved structure and protrudes towards the air outlet end of the air supply duct.
[0012] As a preferred embodiment of the present invention, the air supply duct includes an air outlet section, an air generation section, and an air inlet section, and the fixed pipe and the drive mechanism are both connected to the air generation section.
[0013] As a preferred embodiment of the present invention, the air outlet section and the air generation section are connected by a flange, and the air outlet section is located outside the rotating ring and has a clearance opening corresponding to the transmission gear.
[0014] As a preferred embodiment of the present invention, one end of the air inlet section is fitted inside the air generation section, and a number of studs are fixedly connected to the outer wall of the air inlet section. The side wall of the air generation section has slots that correspond one-to-one with the studs, which facilitates axial movement of the air inlet section and enables installation and disassembly.
[0015] As a preferred embodiment of the present invention, the inner wall of the air inlet section is equipped with a stainless steel mesh.
[0016] As a preferred embodiment of the present invention, the air outlet end of the air outlet section has a constricted structure.
[0017] The present invention has the following beneficial effects:
[0018] This invention uses a fixed pipe inside the air supply duct to rotatably connect to a ventilation duct. The ventilation duct has blades arranged in a circular array on its inner wall. A drive mechanism on the outside of the air supply duct drives the ventilation duct to rotate, and the blades drive the airflow.

Detailed Implementation
[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0034] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.
[0035] Please see Figures 1-3 As shown, the present invention is an environmental protection device for dust removal in mines, including an air supply duct 1, and a spray assembly 101 is provided at the air outlet of the air supply duct 1 to generate water mist at the air outlet of the air supply duct 1.
[0036] like Figures 4-7 As shown, several fixed pipes 102 are fixedly connected to the inner wall of the air supply duct 1. For example, as shown in the figure, there are five fixed pipes 102. Each fixed pipe 102 is rotatably connected to a ventilation pipe 2. The inner wall of the ventilation pipe 2 has blades 201 arranged in a circular array. A drive mechanism is connected to the outer side of the air supply duct 1, and the drive mechanism is connected to the ventilation pipe 2 in a transmission manner. It is used to drive the five ventilation pipes 2 to rotate synchronously, and the blades 201 drive the airflow.
[0037] Specifically, such as Figure 8 and 9 As shown, a gear ring 202 is fixedly connected to the outer wall of the ventilation duct 2, and the driving mechanism includes a rotating ring 3 rotatably connected to the outer wall of the air supply duct 1. An outer gear ring 301 is fixedly connected to the outer wall of the rotating ring 3, and an inner gear ring 302 is fixedly connected to the inner wall of the rotating ring 3, with the inner gear ring 302 meshing with the gear ring 202. A drive motor 303 is fixedly connected to the outer wall of the rotating ring 3, and the drive motor 303 is connected to a transmission gear 304 that meshes with the outer gear ring 301.
[0038] Among them, the five fixed pipes 102 include one fixed pipe 102 coaxially arranged with the air supply duct 1, and the remaining ten fixed pipes 102 are arranged in a circumferential array around it, so that the ventilation pipe 2 located at the center position and the other four ventilation pipes 2 can mesh with each other through the toothed ring 202.
[0039] The internal gear ring 302 meshes with the gear rings 202 of the four ventilation pipes 2 located on the outer side. The drive 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 outer side to rotate through the internal gear ring 302. The four ventilation pipes 2 drive the ventilation pipe 2 located in the center position to rotate through the meshing gear rings 202, so that the five ventilation pipes 2 rotate synchronously.
[0040] The rotation of the ventilation duct 2 causes the internal blades 201 to drive the airflow. The airflow flows through the interior of the ventilation duct 2 and is blown out from the outlet of the air supply duct 1, thereby carrying water mist to remove dust. By driving the airflow through the blades 201, and by placing the drive mechanism on the outside and the blades 201 on the inner wall of the ventilation duct 2, a shaftless structure is formed, which effectively reduces the space occupied inside the air supply duct 1. Under the same air volume, the air supply duct 1 is smaller in size, and fewer components obstruct the internal airflow, thus helping to improve the overall air outlet efficiency.
[0041] As a preferred option, such as Figure 4 and 5 As shown, a fixing plate 103 is fixedly connected to the inner wall of the air supply duct 1. The fixing plate 103 has through holes corresponding to the ventilation pipes 2, and the ventilation pipes 2 are fixedly connected to the side of the fixing plate 103 near the air outlet end of the air supply duct 1. Furthermore, the fixing plate 103 has a spherical curved structure and protrudes towards the air outlet end of the air supply duct 1, so that the fixing plate 103 plays a guiding role in the airflow entering the air supply duct 1, so that the airflow entering the air supply duct 1 flows through the ventilation pipes 2, thereby avoiding the formation of turbulence in the airflow and the resulting impact on airflow efficiency.
[0042] As another preferred implementation, such as Figure 4 and 6 As shown, the air supply duct 1 includes an air outlet section 11, a generating air section 12, and an air inlet section 13, with the fixed pipe 102 and the drive mechanism both connected to the generating air section 12. The air outlet end of the air outlet section 11 has a constricted structure, which increases the airflow velocity at the outlet end and improves the diffusion effect of the water mist.
[0043] The air outlet section 11 and the air supply section 12 are connected by a flange, and the air outlet section 11 is located outside the rotating ring 3 and has a clearance opening corresponding to the transmission gear 304, so that the air outlet section 11 can protect the rotating ring 3 and the ventilation pipe 2.
[0044] In addition, one end of the air inlet section 13 is fitted inside the air supply 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 supply section 12 has slots 105 that correspond one-to-one with the studs 104. The studs 104 are fitted with nuts. The nuts are tightened to fix the position between the air inlet section 13 and the air supply section 12. The slots 105 are opened along the axial direction of the air supply section 12, which facilitates the axial movement of the air inlet section 13 to realize installation and disassembly.
[0045] Furthermore, the inner wall of the air inlet section 13 is equipped with a stainless steel mesh 106. The stainless steel mesh 106 can block leaves or other larger foreign objects from entering the ventilation duct 2 and causing blockage, thereby improving the reliability of use.
[0046] Meanwhile, since the center of the air supply duct 1 is located at the air generation section 12, the bracket for installing the air supply duct 1 can be connected to the air generation section 12. For example, by rotating the connection, it is convenient to adjust the pitch angle of the air supply duct 1, thereby improving the overall practicality.
