Description

Technical Field

[0001] This utility model relates to the field of dust removal and ventilation technology, specifically a multi-functional dust removal and ventilation device for mines. Background Technology

[0002] Dust control and ventilation in mines is one of the core technologies for safe production in mines. Its main purpose is to effectively control the generation and spread of dust, ensure underground air quality, protect workers' health, prevent pneumoconiosis and explosion accidents, and improve operational visibility and production efficiency.

[0003] The air inside existing mines and tunnels contains a large amount of dust particles. These dust particles come into contact with the fan bearings as they are discharged through the fans, and some particles enter the bearings, causing wear. Utility Model Content

[0004] The purpose of this invention is to provide a multi-functional dust removal and ventilation device for mines. After the air has been purified through two stages, namely the water bath chamber and the air exchange chamber, most of the solid dust particles have been removed. Only then does the airflow enter the ventilation fan through the exhaust pipe, thus cutting off the path of dust particles to contact the fan bearings at the source and solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional mine dust removal and ventilation device, including a dust collection box, an air exchange fan at one end of the dust collection box, a motor assembly below the air exchange fan, a maintenance cover at the top of the dust collection box, the maintenance cover being connected to the dust collection box via a slot, the dust collection box including a water bath chamber and an air exchange chamber, wherein the water bath chamber is located below the air exchange chamber, a partition is provided between the water bath chamber and the air exchange chamber, an air exchange pipe is provided inside the dust collection box, the air exchange pipe including a top air outlet and a horizontal air outlet, wherein the top air outlet extends through to the top of the maintenance cover, and the horizontal air outlet extends through to the outside of the dust collection box.

[0006] Preferably, a water bath fitting is provided at the bottom of the ventilation duct, and the water bath fitting extends into the water bath chamber. The ventilation duct and the water bath fitting are connected by an axial flow fan.

[0007] Preferably, slope plates are provided on both sides of the bottom of the water bath chamber, and two circulation bottom pipes are provided below the slope plates, wherein the circulation bottom pipes are interconnected with the water bath chamber.

[0008] Through the above scheme, the special design of the slope plate and the circulating bottom pipe enables the sludge to be automatically collected and easily discharged.

[0009] Preferably, an exhaust duct is provided above the partition, and the exhaust duct is connected to the ventilation fan via a flange.

[0010] Preferably, one end of the water bath pipe is provided with a spiral shaft, which is rotatably connected to the dust collector box through a sealed bearing.

[0011] The above solution allows the rotating spiral shaft to remove deposits from the water bath pipes in real time, completely solving the blockage caused by mud caking in the water bath dust collector.

[0012] Preferably, one end of the spiral shaft is connected to the motor assembly by bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the air purified by the water bath chamber and the air exchange chamber has removed most of the solid dust particles. Only then does the airflow enter the air exchange fan through the exhaust duct, cutting off the path of dust particles to contact the fan bearings at the source. At the same time, the fan is located at the top of the dust collection box and is physically isolated from the water bath chamber by a partition, avoiding the direct intrusion of water mist and settled dust. The motor assembly is placed below the fan, further forming a spatial isolation barrier. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] To address the issue of high dust particle content in the air inside existing mines and tunnels, which causes wear and tear as these dust particles come into contact with the fan bearings during exhaust, some particles may enter the bearings. Please refer to [link to relevant documentation]. Figure 1-2 The present invention provides the following solution:

[0020] refer to Figure 1-2 A multi-functional integrated dust removal and ventilation device for mines includes a dust collection box 1. A ventilation fan 3 is installed at one end of the dust collection box 1, and a motor assembly 4 is installed below the ventilation fan 3. A maintenance cover 101 is installed on the top of the dust collection box 1, and the maintenance cover 101 is connected to the dust collection box 1 via a slot. The dust collection box 1 includes a water bath chamber 102 and a ventilation chamber 103, wherein the water bath chamber 102 is located below the ventilation chamber 103, and a partition 105 is installed between the water bath chamber 102 and the ventilation chamber 103. A ventilation duct 2 is installed inside the dust collection box 1 for ventilation. The duct 2 includes a top air outlet 201 and a horizontal air outlet 202. The top air outlet 201 extends through to the top of the inspection cover 101, and the horizontal air outlet 202 extends through to the outside of the dust collection box 1. Both sides of the bottom of the water bath chamber 102 are provided with slope plates 1021. Two circulation bottom pipes 104 are provided below the slope plates 1021. The circulation bottom pipes 104 are interconnected with the water bath chamber 102. An exhaust duct 301 is provided above the partition 105. The exhaust duct 301 is connected to the ventilation fan 3 through a flange.

[0021] In this embodiment, the dust-laden airflow first enters the ventilation duct 2 through the horizontal air outlet 202 and the top air outlet 201. Driven by the axial flow fan 203, the airflow is forced into the water bath pipe fitting 204 and extends to below the water surface of the water bath chamber 102. When the dust-laden gas passes through the water in the form of bubbles, the dust particles are efficiently captured due to inertial collision, interception, diffusion effect and the wetting effect of water. The removal rate of particles >10μm in the water bath process can reach more than 90%, and it also has a significant effect on respirable dust, greatly reducing the subsequent treatment load. The humid airflow after the water bath rises into the ventilation chamber 103. Due to the presence of the partition 105, the airflow velocity decreases and the direction changes in this space. At this time, the residual water droplets and ultrafine particles that are not captured by the water bath are further settled and separated under the action of gravity and inertia. The dew point effect of the humid air promotes the agglomeration and increase of the fine particles, making them easier to settle.

[0022] After passing through the water bath chamber 102 and the air exchange chamber 103, the air has had most of the solid dust particles removed. Only then does the airflow enter the air exchange fan 3 through the exhaust duct 301, cutting off the path of dust particles to contact the fan bearings at the source. At the same time, the fan is located at the top of the dust collection box and is physically isolated from the water bath chamber by the partition 105, avoiding the direct intrusion of water mist and settled dust. The motor assembly 4 is placed below the fan, further forming a spatial isolation barrier.

[0023] refer to Figure 2The bottom of the ventilation duct 2 is provided with a water bath fitting 204, which extends into the water bath chamber 102. The ventilation duct 2 and the water bath fitting 204 are connected by an axial flow fan 203. One end of the water bath fitting 204 is provided with a spiral shaft 401, which is rotatably connected to the dust collector box 1 through a sealed bearing 402. One end of the spiral shaft 401 is connected to the motor assembly 4 by bolts.

[0024] In this embodiment, the motor assembly 4 drives the spiral shaft 401 to rotate continuously or intermittently inside the water bath pipe 204. Its spiral blades continuously push the sludge deposited at the bottom of the pipe outward to prevent the sludge from accumulating and clogging the pipe, and to ensure that the airflow channel is unobstructed. The V-shaped slope plate 1021 at the bottom of the water bath chamber 102 guides the settled sludge to slide naturally towards the central low-lying area. The collected sludge is discharged from the system through the circulating bottom pipe 104 that is connected to it, realizing convenient centralized cleaning of sludge without stopping the machine to empty the water tank. Another set of circulating bottom pipes 104 can inject water into the water tank.
