Description
Technical Field
[0001] This utility model relates to the field of mine dehumidification technology, and in particular to an underground dehumidification device. Background Technology
[0002] Underground mines are relatively enclosed spaces, and a large amount of moisture can easily accumulate inside, which is detrimental to the working environment for workers and the maintenance environment for equipment. Therefore, dehumidification devices are needed in underground mines to reduce humidity. Generally, dehumidification devices use condensers to condense the moisture in the air, thereby reducing the moisture content. However, the environment in mines contains a lot of dust and other impurities, which easily adhere to the surface of the condenser, hindering the contact and heat exchange between the air and the condenser, resulting in a significant reduction in dehumidification efficiency.

[0034] like Figure 1-7As shown, a downhole dehumidification device includes: a main housing 1, with annular first condensing surface 201, second condensing surface 202, and third condensing surface 203 arranged sequentially along the radial direction gradually approaching the axis. The first condensing surface 201 and the second condensing surface 202 are opposite to each other, and the third condensing surface 203 is arranged opposite to the second condensing surface 202; an exhaust pipe 3, rotatably mounted on the main housing 1, with its lower end extending into the lower part of the third condensing surface 203; and a first scraper 401, vertically disposed between the first condensing surface 201 and the second condensing surface 202, rotating with the exhaust pipe 3. One side of plate 401 slides against the first condensing surface 201; the second scraper 402 is vertically arranged between the first condensing surface 201 and the second condensing surface 202, and rotates with the exhaust pipe 3, with one side of the second scraper 402 sliding against the second condensing surface 202; the third scraper 403 is vertically arranged around the exhaust pipe 3, with one side of the third scraper 403 sliding against the third condensing surface 203; wherein, after the external gas enters the main housing 1, it enters the interior of the third condensing surface 203 from the space between the first condensing surface 201 and the second condensing surface 202, and finally exits from the exhaust pipe 3. It also includes: a baffle 5, which is annular and is disposed on the exhaust pipe 3 between the first condensing surface 201 and the second condensing surface 202, separating the upper space between the first condensing surface 201 and the second condensing surface 202; a first scraper 401 and a second scraper 402 are respectively disposed on the outer and inner sides of the baffle 5; the space between the first condensing surface 201 and the outer side of the baffle 5 is the first condensing space 601; the space between the inner side of the baffle 5 and the second condensing surface 202 is the second condensing space 602; and the space between the third condensing surface 203 and the exhaust pipe 3 is the third condensing space 603. The first condensing space 601 and the second condensing space 602 are connected at the bottom, and the second condensing space 602 and the third condensing space 603 are connected at the top. External gas passes through the first condensing space 601, the second condensing space 602, and the third condensing space 603 in sequence. The exhaust pipe 3 has a mounting plate 301 on its upper part. A partition plate 5 is integrally formed with the first scraper 401 and the second scraper 402. The upper end of the partition plate 5 is integrally formed with the upper end of the third scraper 403 via a sealing plate 404. The circumferential side of the partition plate 5 has several vertically arranged insertion holes 501. It also includes several insertion rods 302, which are mounted on the mounting plate 301 and inserted into the insertion holes 501. The upper part of the exhaust pipe 3 passes through the upper end of the main housing 1, and the exhaust pipe 3 and the upper end of the main housing 1 are rotatably sealed together.
[0035] In operation, there is a gap between the lower end of the exhaust pipe 3 and the lower end of the main housing 1. External gas first enters the first condensation space 601 from above, then the second condensation space 602 from below, then the third condensation space 603 from above, and finally the exhaust pipe 3 from below. The dehumidified gas is then discharged from the exhaust pipe 3. The gas contacts the first condensation surface 201, the second condensation surface 202, and the third condensation surface 203 for heat transfer. Moisture condenses on the surfaces, while dust and other impurities are adsorbed onto them. The exhaust pipe 3 rotates, causing the first scraper 401, the second scraper 402, and the third scraper 403 to rotate, scraping and cleaning the three condensation surfaces, removing condensed water droplets, water films, and dust to maintain cleanliness and condensation dehumidification efficiency. The scraped water can collect and flow downwards, carrying dust downwards and collecting in the lower part of the main housing 1 for centralized treatment, or it can be connected to external collection and treatment equipment.
[0036] The third scraper 403 is distributed in a ring, and the middle part can be sleeved and fixed to the exhaust pipe 3. The partition plate 5, sealing plate 404, first scraper 401, second scraper 402 and third scraper 403 can be an integral structure, all made of rubber, produced in one piece, and fixedly installed on the exhaust pipe 3. The installation is convenient. The second scraper 402 and the first scraper 401 can be fixed in position by inserting the plug rod 302 into the plug hole 501, so as to achieve more stable rotation. At the same time, the upper part between the first condensation surface 201 and the second condensation surface 202 is divided into the first condensation space 601 and the second condensation space 602, forming a bent gas flow path, extending the gas flow path, and facilitating better contact between the gas and the condensation surface, thereby achieving a better dehumidification effect. Furthermore, during the rotation of the scraper, the gas has in-plane displacement, which further extends the gas flow path and increases the contact area.
[0037] Furthermore, the main housing 1 includes an upper housing 101 and a lower cover 102 that are inserted and connected. The first condensing surface 201 is located on the inner wall of the upper housing 101. The upper part of the lower cover 102 has an annular condensing box 1021. The second condensing surface 202 is located on the outer wall of the condensing box 1021. The third condensing surface 203 is located on the inner wall of the condensing box 1021.
[0038] In use, the upper housing 101 and the lower cover 102 are plugged into each other for easy assembly and disassembly, facilitating maintenance and inspection, and allowing for easy replacement of internal components such as scrapers. A low-temperature condensation surface is formed through the condenser box 1021, and refrigerant can flow within the condenser box 1021, which is existing technology. Similarly, the side of the upper housing 101 can also be a condenser box 1021 structure, with the inner wall forming the first condensation surface 201.
[0039] Furthermore, the upper end of the main housing 1 has an air inlet pipe 1011, which is connected to the upper part of the first condensing space 601. The lower end of the main housing 1 has at least two drain pipes 1022, one of which is connected to the lower part of the first condensing space 601 and the second condensing space 602, and the other drain pipe 1022 is connected to the third condensing space 603.
[0040] During use, the main housing 1 can be air-intaken through the upper air intake pipe 1011, and the lower sewage pipe 1022 can be connected to an external collection device to collect the scraped dirt. Alternatively, a valve can be installed on the sewage pipe 1022 to open periodically for sewage discharge.
