Description

Technical Field

[0001] This utility model relates to the field of gold mining technology, specifically a multi-stage ventilation and filtration device suitable for gold mining. Background Technology

[0002] Gold mining operations typically take place in complex underground environments with confined spaces and numerous operational procedures. During processes such as drilling, blasting, loading, and transportation, large amounts of dust are continuously generated. These dust particles vary in size, with some fine particles remaining suspended in the air for extended periods. Simultaneously, various minerals in the gold ore undergo chemical reactions during mining, releasing harmful gases such as sulfur dioxide, carbon monoxide, and nitrogen oxides.

[0003] If these dust particles and harmful gases are not treated promptly and effectively, they will cause many serious problems in gold mining. On the one hand, they pose a great threat to the health of workers. Long-term exposure to such harsh working environments makes workers highly susceptible to occupational diseases such as pneumoconiosis and respiratory diseases, which not only reduces their quality of life but can even endanger their lives. According to relevant statistics, in the gold mining industry, medical expenses and labor losses caused by occupational health problems have brought a heavy economic burden to enterprises.

[0004] On the other hand, deteriorating underground air quality can severely impact the safety and efficiency of mining operations. Dust reduces visibility in the workplace, increasing the probability of accidents such as mechanical collisions and falls. Simultaneously, the accumulation of harmful gases can lead to major safety incidents such as explosions and poisoning, causing irreparable losses to the company and its employees.

[0005] Currently, the ventilation and filtration equipment used in gold mining suffers from numerous shortcomings. Most equipment has a simple filtration system design, possessing only basic primary or secondary filtration functions, making it difficult to cope with the complex underground air environment. Existing filtration technologies cannot achieve ideal removal effects for fine dust and harmful gases. For example, traditional mesh-type filtration equipment can only intercept larger dust particles; its filtration efficiency is low for inhalable particles smaller than 10 micrometers in diameter.

Detailed Implementation

[0025] 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.

[0026] Example 1: To address the issue that traditional mesh-type filtration devices in the prior art can only intercept larger dust particles, and have low filtration efficiency for inhalable particulate matter with a particle size of less than 10 micrometers, please refer to... Figures 1-6 This utility model provides a technical solution:

[0027] A multi-stage ventilation and filtration device suitable for gold mining includes a filter box 1 and an electrical control box 2 fixedly installed on the side of the filter box 1. The electrical control box 2 is used to control the start and stop of the fan 4, the fan 5 and the motor 1042. The filter box 1 is equipped with a multi-stage filtration device, which includes a first filtration mechanism and a second filtration mechanism.

[0028] A partition plate 106 is fixedly connected to the inner wall of the filter box 1 near the bottom. A strip-shaped groove is formed on the upper surface of the partition plate 106. The filter mechanism includes a filter element 104, a mounting base 1041, a motor 1042, a lead screw 1043, a bearing seat 1044, a lead screw nut 1045, a movable plate 1046, a limiting slide rod 1047, and a cleaning brush 1048. The mounting base 1041 is fixedly installed on the top of the partition plate 106, and the filter element 1041 is fixedly connected to the top of the mounting base 1041. The motor 1042... 042 is fixedly installed on the outer surface of filter box 1. The model of motor 1042 is YY90S-4. Bearing seat 1044 is fixedly installed on the outer surface of filter box 1. Lead screw 1043 is connected to the output end of motor 1042. Lead screw nut 1045 is connected to the outer surface of lead screw 1043. Movable plate 1046 is fixedly connected to the side of lead screw nut 1045. Limiting slide rod 1047 is fixedly installed on the top of partition plate 106. Cleaning brush 1048 is fixedly connected to the back of movable plate 1046.

[0029] The filter box 1 has a through groove 107 on the right side, which is wider than the movable plate 1046. The movable plate 1046 moves up and down inside the through groove 107. A ball bearing is installed inside the bearing seat 1044. The top of the lead screw 1043 is connected to the inner ring of the ball bearing. The cleaning brush 1048 contacts one side of the filter element 104. The limiting slide rod 1047 passes through the movable plate 1046 and is slidably connected to its inner wall. During the movement of the movable plate 1046, it will slide on the surface of the slide rod 1047, thereby ensuring the stability of the movable plate 1046 in raising and lowering.

[0030] After the ventilation filtration is completed, the motor 1042 is started first. The output shaft of the motor 1042 drives the lead screw 1043 to rotate. The rotation of the lead screw 1043 causes the lead screw nut 1045 on its surface to move vertically, thereby driving the movable plate 1046 to move up and down. During the movement, the movable plate 1046 drives the cleaning brush 1048 to clean the surface of the filter element 104, thereby reducing the dust adhering to the cleaning metal wire mesh, preventing dust from clogging the filter and affecting the ventilation effect, and also extending the service life of the filter and reducing maintenance costs.

[0031] The second filtration mechanism includes a second filter element 105, a mounting bracket 1051, a pressing bracket 1052, a fixing magnet 1053, and a sliding seat 1054. The sliding seat 1054 is slidably connected to the upper surface of the partition plate 106. The mounting bracket 1051 is fixedly installed on the top of the sliding seat 1054. The pressing bracket 1052 is connected to the top of the mounting bracket 1051. The second filter element 105 is connected to the inside of the mounting bracket 1051. The fixing magnet 1053 is fixedly connected to the top of the inner wall of the filter box 1. The pressing bracket 1052 is made of iron. The bottom of the sliding seat 1054 is connected to the upper surface of the partition plate 106 through a slide rail.

[0032] When installing the second filter mechanism, first open the cover plate 102, push the mounting bracket 1051 to drive the moving seat 1054 to slide on the partition plate 106, then press the pressing bracket 1052 on the top of the mounting bracket 1051 so that both sides of the pressing bracket 1052 are attracted by the fixed magnet 1053. After installing the second filter element 105, thread the cover plate 102 to the top of the filter box 1. The second filter element 105 can be replaced through the detachable second filter element 105, thereby maintaining the air filtration effect.

[0033] The filter box 1 is fixedly connected to the front of the air inlet pipe 101 and the air outlet pipe 103 is fixedly connected to the back of the filter box 1. The top of the filter box 1 is connected to the cover plate 102 by bolts. The first filter element 104 is a dust removal metal wire mesh structure. Large dust particles intercepted on the metal wire mesh will fall into the strip groove and enter the spacer plate 106 below, so that they can be easily sucked away by the negative pressure generated by the fan 4. The second filter element 105 is an electrostatic adsorption non-woven fabric. During the non-woven fabric manufacturing process, a special process is used to make its surface static electricity. When dusty air passes through, the electrostatic adsorption principle is used to capture small particles in the air and improve the filtration efficiency of medium-sized dust particles. A base 3 is fixedly installed at the bottom of the filter box 1. A pull rod 301 is fixedly connected to the front of the base 3. A support plate 302 is fixedly connected to the bottom of the base 3. A caster wheel 303 is fixedly installed at the bottom of the support plate 302. A fan 4 is fixedly installed at the top center of the support plate 302. The air inlet of the fan 4 is equipped with a precision filter screen to prevent dust from entering the interior of the fan 4 and causing damage. The air outlet of the fan 4 is located at the bottom of the filter box 1 and its height is lower than that of the partition plate 106. Therefore, when the movable plate 1046 drives the cleaning brush 1048 down to the bottom of the partition plate 106, the airflow generated by the fan 4 will carry away the dust on the surface of the cleaning brush 1048, thereby cleaning the cleaning brush 1048. A second fan 5 is installed on the back of the filter element 3 6.

[0034] Example 2: To further enhance the filtration effect of ventilation in mining operations, this application includes a filter element 6 fixedly connected to the side of the outlet duct 103 away from the filter box 1. Filter element 6 is composed of composite activated carbon fiber and a photocatalytic decomposition module. The activated carbon fiber is responsible for adsorbing harmful gases, while the photocatalytic decomposition module decomposes harmful gases into harmless substances by irradiating the catalyst with ultraviolet light, further improving the purification effect of harmful gases.

[0035] Working principle: When in use, first start the second fan 5 to generate negative pressure, so that the air enters the interior of the filter box 1 from the air inlet pipe 101. It is first filtered by the first filter element 104 and the second filter element 105, and then enters the third filter element 6 through the air outlet pipe 103. After being filtered by the third filter element 6, it is discharged to the outside.
