Description

Technical Field

[0001] The utility model relates to the technical field of dehumidification equipment, in particular to a dehumidification structure and a moisture absorber. Background Art

[0002] During the operation of a transformer, a certain degree of gas exchange with the outside world is required to maintain the air pressure balance in the fuel tank. To avoid moisture entering the transformer during the gas exchange process, reducing the insulation strength of the insulating oil and affecting the insulation resistance of the transformer winding, etc., we generally install a moisture absorber at the oil conservator of the transformer to absorb the moisture in the exchanged gas to ensure the normal operation of the transformer. After the desiccant inside the existing moisture absorber is saturated, it needs to be regenerated, and the condensed water generated during regeneration will flow out from the drain port under the action of its own gravity. The existence of the drain port easily allows outside air to directly enter the moisture absorber without treatment, thereby affecting the absorption of moisture in the air by the moisture absorber.

[0025] In order to make the above-mentioned objects, features, and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings of the specification.

[0026] Many specific details are set forth in the following description in order to provide a thorough understanding of the present utility model, but the present utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present utility model. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0028] Example 1, refer to Figures 1 to 5 , which is the first embodiment of the present utility model. This embodiment provides a dehumidification structure. The installation component 100 includes an installation housing 101. One end of the installation housing 101 is provided with an air inlet, and the other end is provided with a connection flange 102. When the device exchanges gas with the outside world, the outside air will first enter the installation housing 101 along the air inlet, and then enter the transformer through the installation housing 101. The dehumidification component 200 includes a mesh cylinder 201 arranged inside the installation housing 101 and a desiccant filled inside the mesh cylinder 201. The desiccant is composed of titanium-doped silica gel particles. Through the doping of titanium elements, the adsorption performance of silica gel is enhanced. The titanium atoms change their valence in the silica gel network, resulting in defects in the crystal lattice of the silica gel network, thereby increasing the mesh surface area and improving the adsorption capacity. The metallicity and oxidizing property of titanium are stronger than those of silicon, and the formed oxygen bonds are also stronger. Therefore, it can absorb more moisture. So when the outside air enters the installation housing 101, the moisture contained therein will be absorbed by the titanium-doped silica gel particles, ensuring the dryness inside the conservator. The drainage component 300 includes a drainage cavity 301 formed between the mesh cylinder 201 and the inner wall of the installation housing 101, and a plugging ring groove 302 at the bottom of the drainage cavity 301. The cross-section of the plugging ring groove 302 is conical, and its internal dimensions increase in sequence from top to bottom. A plugging ring block 303 is slidably installed in the plugging ring groove 302, and a drainage hole 306 communicating with the outside is provided at the bottom of the plugging ring groove 302. The setting of the drainage cavity 301 facilitates the discharge of moisture in the titanium-doped silica gel particles. Under normal conditions, the tight fit between the plugging ring block 303 and the plugging ring groove 302 will close the drainage cavity 301. During the drying process of the titanium-doped silica gel particles, the condensed water flowing into the drainage cavity 301 will gather on the plugging ring block 303 under the action of its own gravity. As the weight of the condensed water increases, the plugging ring block 303 will slowly slide downward until there is a gap between its edge and the inner wall of the plugging ring groove 302, and the condensed water above it will flow out of the installation housing 101 along the gap, thus completing the regeneration treatment of the titanium-doped silica gel particles, enabling it to automatically clean the moisture adsorbed inside, ensuring the moisture absorption capacity of the device. In addition, because the internal dimensions of the plugging ring groove 302 increase in sequence from top to bottom, when the outside air wants to enter the inside of the installation housing 101 along the plugging ring groove 302, it will push the plugging ring block 303 to automatically block the plugging ring groove 302, preventing the untreated air from directly entering the installation housing 101 and ensuring the dehumidification effect of the device on the exchanged air.

[0029] Further, the flow discharge component 300 further includes a sliding hole provided in the installation housing 101. A sliding rod 304 fixedly connected to the plugging ring block 303 is slidably installed in the sliding hole, and a telescopic spring 305 fixedly connected to the sliding hole is provided on the upper part of the sliding rod 304. The arrangement of the sliding hole and the sliding rod 304 ensures the stability of the plugging ring block 303 moving in the plugging ring groove 302. The arrangement of the telescopic spring 305 can accelerate the reset of the plugging ring block 303 and further prevent external impurities from entering the installation housing 101.

[0030] During use, through the cooperation of the plugging ring groove 302 and the plugging ring block 303, untreated air is prevented from directly entering the installation housing 101, the influence of impurities in the air on the moisture absorption effect is reduced, and the dehumidification quality of the device for exchanging air is ensured.

[0031] Embodiment 2, refer to Figures 1 to 5 , which is the second embodiment of the present utility model. Different from the previous embodiment, a plurality of baffle plates 204 are rotatably installed at one end of the inner cavity of the installation housing 101 close to the connecting flange 102, and the baffle plates 204 are all inclined. As Figure 2 shown, the heating resistance wire 202 is arranged at a position far from the baffle plate 204, so the temperature on the surface of the baffle plate 204 is lower than the temperature in the mesh cylinder 201. During the drying treatment of the titanium-doped silica gel particles, the upward airflow in the installation housing 101 will be blocked by the baffle plate 204 and prevented from directly entering the oil conservator. The water vapor entrained therein will be condensed into liquid after contacting the baffle plate 204 and flow downward along the inclination angle of the baffle plate 204, thus preventing moisture from entering the oil conservator and ensuring the dry environment inside it.

[0032] Further, a transmission cavity is provided inside the installation housing 101, and a transmission member 205 coaxially fixed to the baffle plate 204 is provided in the transmission cavity. A limiting arc groove 207 is opened on the inner wall of the transmission cavity, and a limiting arc rod 206 fixedly connected to the transmission member 205 is slidably installed in the limiting arc groove 207, and a limiting spring 208 fixedly connected to the limiting arc groove 207 is provided at one end of the limiting arc rod 206. Since the transmission member 205 is coaxially fixed to the baffle plate 204, it will drive the transmission member 205 to move synchronously. When the baffle plate 204 is impacted by the airflow and rotates to a certain extent, but under the limitation of the limiting spring 208 and the limiting arc rod 206, the baffle plate 204 will not rotate too large an angle, so that the lowest end of the baffle plate 204 can only move in the flow discharge cavity 301 and will not move above the mesh cylinder 201, thereby avoiding the situation where condensed water falls onto the mesh cylinder 201 and reducing the difficulty of regenerating the titanium-doped silica gel particles.

[0033] Further, an impact protrusion 209 that contacts the transmission member 205 is provided inside the transmission cavity. During the rotation of the baffle 204, the transmission member 205 fixed coaxially therewith will continuously collide with the impact protrusion 209, thereby causing the vibration of the baffle 204 and accelerating the shedding of water droplets thereon.

[0034] Further, a conical sleeve 203 is installed at one end of the mesh cylinder 201 close to the baffle 204, and the edge of the conical sleeve 203 is away from the outer wall of the mesh cylinder 201. Since the edge of the conical sleeve 203 is away from the outer wall of the mesh cylinder 201, the falling liquid droplets will be guided by the conical sleeve 203 away from the mesh cylinder 201 and will not flow into the mesh cylinder 201 through the holes on the mesh cylinder 201 to increase the difficulty of titanium-doped silica gel particle regeneration.

[0035] Further, the dehumidification assembly 200 further includes a heating cavity provided at one end of the mesh cylinder 201 close to the air inlet, and a heating resistance wire 202 is provided in the heating cavity. A starting device is provided in the installation housing 101, which can regularly start the operation of the heating resistance wire 202, thereby increasing the temperature in the inner cavity of the mesh cylinder 201 to perform the drying operation on the titanium-doped silica gel particles. The water vapor generated during the drying process diffuses around by convection, reaches the inner wall of the installation housing 101 through the holes on the mesh cylinder 201, and condenses on the inner wall of the installation housing 101. The condensed water droplets flow downward along the installation housing 101 and flow out of the device through the drain assembly 300, so as to achieve the purpose of maintenance-free of the device.

[0036] During use, through the setting of the baffle 204, the upward airflow can be blocked during the regeneration of the titanium-doped silica gel particles, so that the water vapor therein condenses into a liquid and flows along the baffle 204 into the drain cavity 301, ensuring the dryness of the air inside the oil conservator.

[0037] Embodiment 3, referring to Figure 6 , which is the third embodiment of the present utility model. This embodiment further provides a moisture absorber. It includes a dust removal assembly 400, which includes a fixed sleeve 401 fixedly installed at the air inlet of the installation housing 101. A plurality of impurity removal grooves 402 are provided on the outer wall of the fixed sleeve 401, and an air inlet sleeve 403 communicating with the inner cavity of the mesh cylinder 201 is provided inside the fixed sleeve 401, and a plurality of dust removal filters 404 are provided outside the air inlet sleeve 403. The settings of the impurity removal grooves 402 and the dust removal filters 404 can filter the airflow entering the inside of the installation housing 101 to prevent solid impurities therein from affecting the water absorption effect of the titanium-doped silica gel particles.

[0038] Further, a connecting thread detachably connected to the installation housing 101 is provided on the upper part of the air inlet sleeve 403. The connecting thread enables the air inlet sleeve 403 to be detachably connected to the installation housing 101, so that the staff can disassemble it to clean the dust thereon, ensuring the airflow efficiency.

[0039] During use, through the settings of the impurity removal tank 402 and the dust removal filter screen 404, solid impurities in the exchanged air are filtered to prevent them from affecting the water absorption effect of the titanium-doped silica gel particles, and the convenience of the air inlet sleeve 403 is increased by using the connection thread setting.
