Description

Technical Field

[0001] The present invention relates to the technical field of granary air conditioners, and more specifically, to an airtight granary air conditioner with dynamic anti-fumigation corrosion prevention. Background Art

[0002] When modern granaries store grains, in order to maintain the storage state of the grains, it is usually necessary to install special granary air conditioners to adjust the temperature and humidity inside the granary. In addition, during the process of grain storage, grain fumigation is an important operation for pest control in grain storage. That is, when the pest infection of grains (including finished grains, raw grains, oilseeds, dried sweet potatoes, seed grains, etc.) reaches a certain level, under sealed conditions, a certain amount of drugs such as aluminum phosphide, calcium phosphide, and zinc phosphide are buried in the grain pile, so that the above-mentioned phosphides absorb the moisture in the voids of the grain pile and in the grains, produce chemical reactions, and release highly toxic phosphine gas to achieve the effect of killing various pests and insect eggs in the grain pile.

[0003] In order to ensure the closed state inside the granary, granary air conditioners usually have high airtightness requirements. However, the phosphine gas generated during granary fumigation flowing into the air conditioner will corrode the components and affect the normal operation of the air conditioner. Existing granary air conditioners usually use coating methods to reduce the damage of phosphine to the body. However, for air conditioners used for a long time, the effect is poor. At the same time, the connection between the air conditioner and the air delivery pipe is prone to leakage, which will cause danger during granary fumigation, and it is inconvenient to replace the air delivery pipe. On the other hand, due to the warm and humid air inside the granary, the air conditioner will generate more condensate during the refrigeration process, which will also cause harm to the air conditioner if not handled in time.

Detailed implementation mode

[0034] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation modes.

[0035] As Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 11 As shown in

[0036] Specifically, as Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10As shown, the sealing structure 3 includes a mounting backplate 302. The mounting backplate 302 is fixedly connected to the side of the air conditioner main body 1. Two air outlets 303 are provided on the mounting backplate 302. A sealing plate 304 is slidably connected to the inner side of the mounting backplate 302. A lead screw 309 is threadedly connected to the middle of the sealing plate 304. The end of the lead screw 309 is rotatably connected to the mounting backplate 302. A motor 301 is installed on the side of the air conditioner main body 1. The end of the motor 301 is fixedly connected to the end of the lead screw 309 through a coupling. A sealing pipe 305 is slidably connected to the mounting backplate 302 through the air outlet 303. A first spring 306 is fixedly connected between the end of the sealing pipe 305 and the mounting backplate 302. A first washer 307 is fixedly connected to the side of the sealing pipe 305. A second washer 308 is fixedly connected to the end of the sealing pipe 305. The side of the sealing pipe 305 abuts against the inner side of the mounting backplate 302 through the first washer 307. The end of the sealing pipe 305 abuts against the side of the sealing plate 304 through the second washer 308. A convex block 310 is fixedly connected to the side of the sealing pipe 305. The convex block 310 has a hemispherical structure. The convex block 310 and the sealing plate 304 are located on the same plane;

[0037] The motor 301 drives the lead screw 309 to rotate, so as to adjust the position of the closing plate inside the mounting backplate 302. When the closing plate moves to the air outlet 303 provided on the mounting backplate 302, the inside of the air conditioner can be closed, thereby completely preventing the entry of corrosive gases. A sealing pipe 305 is provided on the side of the closing plate. The end and the side of the sealing pipe 305 improve the sealing effect through the second washer 308 and the first washer 307. On the other hand, in order to avoid affecting the sealing effect of the second washer 308 due to the sliding of the closing plate, a convex block 310 is provided on the side of the sealing pipe 305. During the process of the closing plate moving to close the air outlet 303, the closing plate will slide relative to the convex block 310. Due to the supporting effect of the closing plate, at this time, the second washer 308 at the end of the sealing pipe 305 will not relatively rub against the closing plate. Until the closing plate moves into place, the convex block 310 loses the supporting effect. Under the push of the first spring 306, the sealing pipe 305 slides and completes the sealing of the air outlet 303, thereby maintaining the sealing effect of the structure for a long time.

[0038] Specifically, such as Figure 2 、 Figure 3 、 Figure 10As shown, the air supply structure 4 includes a fan 401. The fan 401 is installed inside the air conditioner main body 1. A heat exchanger 403 is installed at the bottom side of the air conditioner main body 1 with respect to the fan 401. A partition plate 402 is provided between the fan 401 and the heat exchanger 403. The sides of the partition plate 402 are fixedly connected between the air conditioner main body 1 and the installation back plate 302 respectively. The middle of the partition plate 402 communicates with the end of the fan 401. A filter plate 406 is installed inside the partition plate 402. The output end of the fan 401 is fixedly connected to the side of the installation back plate 302. A connecting pipe 404 abuts against one side of the sealing plate 304 adjacent to the fan 401. The connecting pipe 404 is slidably connected to the inside of the installation back plate 302. A second spring 405 is fixedly connected between the connecting pipe 404 and the installation back plate 302. The edge of the connecting pipe 404 is of an inclined surface structure. Through the air supply structure 4, the smooth flow of air can be ensured.

[0039] When the sealing plate 304 is in the open state, under the push of the second spring 405, the connecting pipe 404 moves to one side until it is connected to the end of the sealing pipe 305. At this time, a complete air duct is formed, which is conducive to the flow of air. When the sealing plate 304 seals the air outlet 303, due to the inclined surface structure at the end edge of the connecting pipe 404, the movement of the sealing plate 304 will push the connecting pipe 404 to retract, and will not affect the movement of the sealing plate 304.

[0040] Specifically, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 9 、 Figure 10 As shown, the connection structure 2 includes a connection sleeve 202. The connection sleeve 202 is fixedly connected to the air outlet 303 on the installation back plate 302. The side of the connection sleeve 202 is of a conical surface structure. A duct 201 is sleeved outside the connection sleeve 202. A threaded sleeve 203 abuts against the outside of the duct 201. The inside of the threaded sleeve 203 abuts against the connection sleeve 202 through the duct 201. A guide rod 204 is vertically fixedly connected to the side of the installation back plate 302. The threaded sleeve 203 is slidably connected to the guide rod 204. A fastening sleeve 205 is rotatably connected to the installation back plate 302. The inside of the fastening sleeve 205 is threadedly connected to the outside of the threaded sleeve 203.

[0041] Rotate the fastening sleeve 205, and continue to drive the threaded sleeve 203 to move towards the connecting sleeve 202 through the threaded structure. At this time, since the inner side of the threaded sleeve 203 is also a conical surface structure, the threaded sleeve 203 will cooperate with the connecting sleeve 202 to squeeze and fix the air duct 201 in the middle during the movement, avoiding gas leakage at the connection, and facilitating the disassembly and assembly of the air duct 201.

[0042] Specifically, as Figure 4 , Figure 6 , Figure 8 shown, the fastening structure 6 includes a rotating block 602. A rotating block 602 is provided on the side of the fastening sleeve 205. The end of the rotating block 602 is rotatably connected to the mounting back plate 302. A worm 603 is rotatably connected to the middle of the rotating block 602. A threaded tooth groove 601 is formed on the side of the fastening sleeve 205. The worm 603 is engaged with the fastening sleeve 205 through the threaded tooth groove 601. A torsion spring 607 is fixedly connected between the rotating block 602 and the mounting back plate 302. A clamping rod 604 is slidably connected to the inner side of the rotating block 602. A third spring 605 is fixedly connected between the clamping rod 604 and the rotating block 602. A positioning hole 606 is formed on the mounting back plate 302. The end of the clamping rod 604 is engaged with the mounting back plate 302 through the positioning hole 606;

[0043] After rotating the fastening sleeve 205 to complete the preliminary fixation of the air duct 201, in order to further increase the pressure exerted by the fastening sleeve 205 on the air duct 201, the user can rotate the rotating block 602 to the horizontal state, and then release the clamping rod 604 so that its end is engaged with the positioning hole 606 on the mounting back plate 302. At this time, the rotating block 602 is fixed to the horizontal state, and the worm 603 on the side of the rotating block 602 will be engaged with the threaded tooth groove 601 formed on the fastening sleeve 205. At this time, rotating the worm 603 can continue to drive the fastening sleeve 205 to rotate, obtaining a better connection effect. At the same time, a torsion spring 607 is connected between the rotating block 602 and the mounting back plate 302, so that the rotating block 602 can automatically turn to one side when not in use, facilitating the user to rotate the fastening sleeve 205.

[0044] Specifically, as Figure 2 , Figure 5 , Figure 6 , Figure 9 , Figure 10 , Figure 11As shown, the water collection structure 5 includes a water collection tray 501. The water collection tray 501 is provided at the bottom side of the heat exchanger 403. The side of the water collection tray 501 is fixedly connected to the inner side of the air conditioner main body 1. The middle part of the water collection tray 501 is in a funnel-shaped structure. A water leakage hole 508 is opened in the middle part of the water collection tray 501. A transmission gear ring 503 is rotatably connected to the middle part of the water collection tray 501. A scraping rod 504 is fixedly connected to the inner side of the transmission gear ring 503. The bottom side of the scraping rod 504 is slidably connected to the water collection tray 501. A gear 507 is rotatably connected to the side of the air conditioner main body 1. The side of the gear 507 meshes with the transmission gear ring 503. A second pulley 506 is fixedly connected to the end of the gear 507. A first pulley 502 is fixedly connected to the lead screw 309. A transmission belt 505 is sleeved between the first pulley 502 and the second pulley 506. The diameter of the first pulley 502 is larger than the diameter of the second pulley 506;

[0045] The middle part of the water collection tray 501 is in a funnel-shaped structure, so that the condensed water drops onto the water collection tray 501 and then falls into the bottom side of the water collection tray 501 through the water leakage hole 508, which is convenient for subsequent centralized treatment. At the same time, when the motor 301 drives the lead screw 309 to rotate, through the driving effect of the first pulley 502, the second pulley 506 and the transmission belt 505, the gear 507 will rotate, and the gear 507 will further drive the transmission gear ring 503 to rotate in the middle of the water collection tray 501. At this time, the scraping rod 504 arranged on the inner side of the transmission gear ring 503 will scrape the surface of the water collection tray 501, improving the collection effect of the condensed water.

[0046] Specifically, as Figure 11 、 Figure 12 shown, the release structure 7 includes a sliding groove 702. The sliding groove 702 is opened at the bottom of the air conditioner main body 1. The air conditioner main body 1 is slidably connected with a sealing plug 701 through the sliding groove 702. The sealing plug 701 passes through the water collection tray 501 through the water leakage hole 508. The side of the sealing plug 701 abuts against the surface of the water collection tray 501. A fourth spring 703 is fixedly connected between the sealing plug 701 and the air conditioner main body 1. A corrugated groove 704 is opened on the side of the sealing plug 701. A pushing sleeve ring 705 is rotatably connected to the sealing plug 701 through the corrugated groove 704. A convex structure is provided on the top side of the pushing sleeve ring 705. The side of the pushing sleeve ring 705 is fixedly connected to the end of the scraping rod 504;

[0047] The condensed water collected at the bottom side of the water collecting tray 501 will be re-evaporated by the hot air entering the air conditioner, which increases the humidity of the air. However, the granary storage requires a low-temperature and dry environment. A sealing plug 701 is provided in the middle of the water collecting tray 501. Under the traction of the fourth spring 703, the sealing plug 701 seals the water leakage hole 508 in the middle of the water collecting tray 501 to independently store the condensed water collected at the bottom side of the water collecting tray 501. The condensed water collected on the water collecting tray 501 will be concentrated on the water collecting tray 501. During this process, when the scraping rod 504 rotates with the transmission gear ring 503, the pushing sleeve ring 705 connected to the end of the scraping rod 504 will rotate in the corrugated groove 704 on the sealing plug 701. A convex structure is provided on the top side of the pushing sleeve ring 705. In cooperation with the corrugated groove 704 and the fourth spring 703 at the bottom side, the sealing plug 701 will reciprocate in the vertical direction, thereby intermittently opening the water leakage hole 508, and discharging the condensed water on the water collecting tray 501 to the bottom side of the water collecting tray 501. After the transmission gear ring 503 stops rotating, the sealing plug 701 re-seals the water leakage hole 508. At this time, the condensed water on the water collecting tray 501 is completely discharged to the bottom, avoiding the re-evaporation of the condensed water and improving the drying effect on the air in the granary.

[0048] When the present invention is in use, first, in order to prevent corrosive gas from entering the air conditioner interior along the air duct during the granary fumigation process, a slidable closing plate is provided in the mounting back plate 302 on the side of the air conditioner main body 1. The motor 301 on the side of the air conditioner main body 1 is electrically connected to an external power supply. By driving the lead screw 309 to rotate with the motor 301, the position of the closing plate within the mounting back plate 302 can be adjusted. When the closing plate moves to the air outlet 303 formed in the mounting back plate 302, the interior of the air conditioner can be closed, thus completely preventing the entry of corrosive gas. A sealing pipe 305 is provided on the side of the closing plate. The sealing effect of the end and side of the sealing pipe 305 is improved by the second gasket 308 and the first gasket 307. On the other hand, in order to prevent the sliding of the closing plate from affecting the sealing effect of the second gasket 308, a convex block 310 is provided on the side of the sealing pipe 305. During the process of the closing plate moving to close the air outlet 303, the closing plate will slide relative to the convex block 310. Due to the supporting effect of the closing plate, at this time, the second gasket 308 at the end of the sealing pipe 305 will not rub against the closing plate. Until the closing plate moves into place, the convex block 310 loses its supporting effect. Under the push of the first spring 306, the sealing pipe 305 slides and completes the sealing of the air outlet 303, thereby maintaining the sealing effect of the structure for a long time. The fan 401 installed inside the air conditioner main body 1 is used to drive the air flow to circulate. In order to make the air flow more smooth, a partition plate 402 is provided on the bottom side of the fan 401. At the same time, a filter plate 406 is arranged inside the partition plate 402 for filtering moisture and dust in the air. The side of the fan 401 is communicated with the mounting back plate 302, and a connecting pipe 404 is provided in the mounting back plate 302. When the sealing plate 304 is in the open state, under the push of the second spring 405, the connecting pipe 404 moves to one side until it is connected to the end of the sealing pipe 305. At this time, a complete air duct is formed, which is conducive to the flow of air. When the sealing plate 304 seals the air outlet 303, since the edge of the end of the connecting pipe 404 is of an inclined surface structure, the movement of the sealing plate 304 will push the connecting pipe 404 to retract, and will not affect the movement of the sealing plate 304. A connecting sleeve 202 is provided on the side of the mounting back plate 302 for installing the air duct 201. In order to ensure the sealing effect at the connection of the air duct 201, the outer side of the connecting sleeve 202 is of a conical surface structure. During installation, the user passes the air duct 201 through the threaded sleeve 203 and then moves the threaded sleeve 203 along the guide rod 204 towards the connecting sleeve 202. When the threaded sleeve 203 contacts the fastening sleeve 205, rotate the fastening sleeve 205, and continue to drive the threaded sleeve 203 to move towards the connecting sleeve 202 through the threaded structure. At this time, since the inner side of the threaded sleeve 203 is also of a conical surface structure, the threaded sleeve 203 will cooperate with the connecting sleeve 202 to squeeze and fix the air duct 201 in the middle during the movement process, avoiding gas leakage at the connection and facilitating the disassembly and assembly of the air duct 201.Since the end of the air duct 201 is fixed in a threaded manner through the threaded sleeve 203, in order to make the connection stronger and avoid loosening, a rotating block 602 is provided on the side of the fastening sleeve 205. After the user initially fixes the air duct 201 by rotating the fastening sleeve 205, in order to further increase the pressure exerted by the fastening sleeve 205 on the air duct 201, the user can rotate the rotating block 602 to the horizontal state, and then release the engaging rod 604 so that its end engages with the positioning hole 606 on the mounting backplate 302. At this time, the rotating block 602 is fixed to the horizontal state, and the worm 603 on the side of the rotating block 602 will engage with the threaded tooth groove 601 provided on the fastening sleeve 205. At this time, rotating the worm 603 can continue to drive the fastening sleeve 205 to rotate to obtain a better connection effect. At the same time, a torsion spring 607 is connected between the rotating block 602 and the mounting backplate 302, so that the rotating block 602 can automatically turn to one side when not in use, facilitating the user to rotate the fastening sleeve 205. A water collecting tray 501 is provided at the bottom side of the heat exchanger 403. During the process of the heat exchanger 403 cooling the air, condensed water will appear. Since the air in the granary is relatively humid and hot, the air conditioner may generate more condensed water during operation. The middle part of the water collecting tray 501 is in a funnel-shaped structure, so that the condensed water drips onto the water collecting tray 501 and then falls into the bottom side of the water collecting tray 501 through the water leakage holes 508, facilitating subsequent centralized treatment. At the same time, when the motor 301 drives the lead screw 309 to rotate, through the driving effect of the first pulley 502, the second pulley 506 and the transmission belt 505, the gear 507 will rotate, and the gear 507 will further drive the transmission gear ring 503 to rotate in the middle of the water collecting tray 501. At this time, the scraping rod 504 provided on the inner side of the transmission gear ring 503 will scrape the surface of the water collecting tray 501 to improve the collection effect of the condensed water. The condensed water collected at the bottom side of the water collecting tray 501 will be re-evaporated by the hot air entering the air conditioner to increase the humidity of the air. Since the granary storage needs to maintain a low-temperature and dry environment, a sealing plug 701 is provided in the middle of the water collecting tray 501. The sealing plug 701 will seal the water leakage holes 508 in the middle of the water collecting tray 501 under the traction of the fourth spring 703 to independently store the condensed water collected at the bottom side of the water collecting tray 501, while the condensed water collected on the water collecting tray 501 will be concentrated on the water collecting tray 501. During this process, when the scraping rod 504 rotates with the transmission gear ring 503, the pushing sleeve ring 705 connected to the end of the scraping rod 504 will rotate in the corrugated groove 704 on the sealing plug 701. The top side of the pushing sleeve ring 705 is provided with a convex structure, and together with the corrugated groove 704 and the fourth spring 703 at the bottom side, it will cause the sealing plug 701 to move reciprocally in the vertical direction, thereby intermittently opening the water leakage holes 508, so as to discharge the condensed water on the water collecting tray 501 to the bottom side of the water collecting tray 501. After the transmission gear ring 503 stops rotating, the sealing plug 701 will seal the water leakage holes 508 again.At this time, the condensed water on the water collecting tray 501 is completely discharged to the bottom, avoiding the secondary evaporation of the condensed water and improving the drying effect on the air in the granary.
