Abstract
Description
Technical Field
[0001] This utility model relates to the field of ventilation device technology, specifically a ventilation device with a heat exchange structure for new and old air. Background Technology
[0002] Large-scale livestock farms need to use ventilation devices to ventilate the indoor area during the breeding process, expelling indoor air to the outside, improving the indoor breeding environment and ensuring the healthy development of livestock. Its main function is to ensure the air quality in the farm, reduce the incidence and mortality of animal diseases, and improve production efficiency and breeding quality.
[0003] When existing ventilation systems are in use, the temperature of the fresh air drawn in is relatively low, and the air drawn out from the farm will also release warm air. As a result, the air exchanged by the ventilation system will cause the temperature inside the farm to drop, which will affect the livestock raised inside, making the ventilation system inconvenient to use. Utility Model Content
[0004] The purpose of this invention is to provide a ventilation device with a structure for exchanging heat between new and old air, so as to solve the problem mentioned in the background art that ventilation devices are not easy to exchange heat between new and old air.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a ventilation device with a heat exchange structure for new and old air, comprising a ventilation device body, an old air inlet, an old air connecting pipe, and a new air inlet. One end of the ventilation device body is provided with an old air inlet, and one end of the old air inlet is connected to the old air connecting pipe. A new air inlet is provided on the side of the ventilation device body near the old air inlet. The new air inlet and the old air inlet are staggered in their arrangement on the ventilation device body. A heat exchange mechanism extending outwards is provided inside the ventilation device body. The heat exchange mechanism includes a new air connecting pipe, fixing blocks, and a protective net. A new air connecting pipe is provided on one side of each of the two new air inlets. Symmetrically distributed fixing blocks are provided at one end of the ventilation device body, and protective nets are provided on the surfaces of the two fixing blocks.
[0006] Preferably, the ventilation device body has symmetrically distributed cavities at one end near the fixed block, and vertical rods are provided inside the cavities, with displacement blocks provided on the surface of the vertical rods.
[0007] Preferably, a first spring is welded between the displacement block and the cavity, a locking rod extending to the outside of the ventilation device body is provided on one side of the displacement block, and a pull rod is provided on one side of the locking rod.
[0008] Preferably, the surface of the old air connection pipe is provided with an odor removal mechanism, which includes a filter box, a mounting block, an activated carbon adsorption plate, a docking rod, a connecting plate, a rotating rod, a T-shaped rod, a second spring, a limiting rod, and an insertion rod. The surface of the old air connection pipe is provided with a filter box, and the filter box is provided with symmetrically distributed mounting blocks. The filter box is provided with activated carbon adsorption plates extending into the mounting blocks.
[0009] Preferably, the top of the filter box is provided with symmetrically distributed docking rods, and the surface of the docking rods is provided with connecting plates.
[0010] Preferably, both sides of the connecting plate are rotatably connected to rotating rods via hinge seats, and the rotating rods are provided with T-shaped rods extending to the outside.
[0011] Preferably, a second spring is welded between the T-shaped rod and the rotating rod, a limiting rod is provided at the top of the T-shaped rod, and an insert rod extending into the docking rod is provided on one side of the limiting rod.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This ventilation device with a heat exchange structure for new and old air allows hot air from inside the farm to enter the old air connection pipe while outside air enters the new air connection pipe. This allows the hot air inside the old air connection pipe to heat the air inside the new air connection pipe, enabling the heated and purified air inside the new air connection pipe to enter the farm. This avoids the ventilation device lowering the temperature inside the farm. When the air from inside the farm is discharged through the old air connection pipe, it will have a strong odor. This odor can be absorbed by the activated carbon adsorption plate inside the filter box, thus removing the odor from the discharged air. Attached Figure Description

Detailed Implementation
[0020] 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.
[0021] Please see Figure 1 , Figure 2 and Figure 4 As can be seen, the ventilation device with a heat exchange structure for new and old air provided by this utility model includes a ventilation device body 1, an old air inlet 2, an old air connecting pipe 3, and a new air inlet 4. The old air inlet 2 is located at one end of the ventilation device body 1, and the old air inlet 2 is connected to the old air connecting pipe 3 at one end. The new air inlet 4 is located on the side of the ventilation device body 1 closest to the old air inlet 2. The new air inlet 4 and the old air inlet 2 are staggered in the ventilation device body 1. A heat exchange mechanism 5 extending to the outside is provided inside the ventilation device body 1. The heat exchange mechanism 5 includes a new air connecting pipe 501, a fixing block 502, and a protective net 503. A fresh air connection pipe 501 is provided on one side of the fresh air inlet 4. A symmetrically distributed fixing block 502 is provided at one end of the ventilation device body 1. A protective net 503 is provided on the surface of the two fixing blocks 502. A symmetrically distributed cavity 504 is opened at one end of the ventilation device body 1 near the fixing block 502. A vertical rod 505 is provided inside the cavity 504. A displacement block 506 is provided on the surface of the vertical rod 505. A first spring 507 is welded between the displacement block 506 and the cavity 504. A locking rod 508 extending to the outside of the ventilation device body 1 is provided on one side of the displacement block 506. A pull rod 509 is provided on one side of the locking rod 508.
[0022] See Figure 1 , Figure 2 and Figure 4It is known that when hot air inside the farm enters the old air connection pipe 3 through the old air inlet 2, and at the same time, outside air enters the fresh air connection pipe 501 through the fresh air inlet 4, the hot air inside the old air connection pipe 3 heats the air inside the fresh air connection pipe 501. This allows the heated, clean air inside the fresh air connection pipe 501 to enter the farm, thus preventing the ventilation system from lowering the temperature inside the farm. Furthermore, when air enters the fresh air connection pipe 501 through the fresh air inlet 4, impurities or flying insects in the air can easily enter the fresh air connection pipe 501. The lever 509 can be pulled first to allow this to be addressed. The locking rod 508 can be moved, and when the locking rod 508 moves, it can also move the displacement block 506, so that the displacement block 506 can squeeze the first spring 507 when it moves. Then, the protective net 503 is inserted into the surface of the fixing block 502. Then, the pull rod 509 is loosened. Through the reset effect of the first spring 507, the locking rod 508 and the fixing block 502 can be locked, so that the protective net 503 can be installed on one side of the fresh air inlet 4. This makes the air entering the fresh air inlet 4 purer and allows for heat exchange, making the ventilation device more convenient to use in the farm.
[0023] See Figure 1 , Figure 3 , Figure 5 and Figure 6 It is known that the surface of the old air connection pipe 3 is provided with an odor removal mechanism 6, which includes a filter box 601, a mounting block 602, an activated carbon adsorption plate 603, a docking rod 604, a connecting plate 605, a rotating rod 606, a T-shaped rod 607, a second spring 608, a limiting rod 609, and an insertion rod 610. The surface of the old air connection pipe 3 is provided with a filter box 601, and the filter box 601 is provided with symmetrically distributed mounting blocks 602. The filter box 601 is provided with activated carbon adsorption plates extending into the mounting blocks 602. Plate 603, filter box 601 has symmetrically distributed docking rods 604 at the top. The surface of the docking rod 604 is provided with a connecting plate 605. Both sides of the connecting plate 605 are rotatably connected to a rotating rod 606 through a hinge seat. The rotating rod 606 has a T-shaped rod 607 extending to the outside inside. A second spring 608 is welded between the T-shaped rod 607 and the rotating rod 606. The top of the T-shaped rod 607 is provided with a limiting rod 609. One side of the limiting rod 609 is provided with an insertion rod 610 extending into the docking rod 604.
[0024] See Figure 1 , Figure 3 , Figure 5 and Figure 6It is known that when the air inside the farm enters the old air connection pipe 3 and is discharged, the air will have a strong odor. The odor in the air can be adsorbed by the activated carbon adsorption plate 603 inside the filter box 601. When the activated carbon adsorption plate 603 is used for a long time, the adsorption effect will decrease. First, pull the insertion rod 610 so that the insertion rod 610 can be separated from the docking rod 604. Then pull the limiting rod 609 so that the limiting rod 609 can drive the T-shaped rod 607 to move when it moves. When the T-shaped rod 607 moves, it can squeeze the second spring 608. Then rotate the rotating rod 606 so that the limiting rod 609 can be separated from the docking rod 604. This allows the connecting plate 605 to be pulled so that the connecting plate 605 can drive the activated carbon adsorption plate 603 connected at one end to be taken out. This allows the activated carbon adsorption plate 603 to be cleaned or replaced quickly, thus removing the odor from the discharged air and achieving a good odor removal effect.
[0025] In summary, large-scale livestock farms require ventilation systems to ventilate the indoor area during the breeding process. When hot air from inside the farm enters the old air inlet 2 into the old air connection pipe 3, and simultaneously, outside air enters the new air inlet 4 into the new air connection pipe 501, the hot air inside the old air connection pipe 3 heats the air inside the new air connection pipe 501. This heated, purified air then enters the farm, preventing the ventilation system from lowering the internal temperature. When the air inlet 4 enters the fresh air connection pipe 501, impurities or flying insects in the air can easily enter the fresh air connection pipe 501. First, pull the lever 509 to move the locking lever 508. Then, insert the protective net 503 into the surface of the fixing block 502. Then, loosen the lever 509 to lock the locking lever 508 and the fixing block 502. This allows the protective net 503 to be installed on one side of the fresh air inlet 4, making the air entering the fresh air inlet 4 purer and enabling heat exchange. This makes the ventilation device more convenient to use in the farm.
