DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0025] First embodiment:

[0026] like Figure 1-4 As shown, the pig house exhaust device provided by the utility model includes: a ventilation mechanism 100 and a main body mechanism 200, the ventilation mechanism 100 is installed on the main body mechanism 200, the main body mechanism 200 refers to the pig house of the prior art, the ventilation mechanism 100 is used to ventilate the main body mechanism 200, the main body mechanism 200 includes a pig house main body 201, the pig house main body 201 is provided with a roof 202, the lower end of the roof 202 is provided with a ceiling 203, the ceiling 203 divides the pig house main body 201 into two upper and lower spaces, the upper and lower spaces are surrounded by walls and the roof 202 on all sides, and are isolated from the external environment, the ventilation mechanism 100 includes an air inlet pipe 103, the air inlet pipe 103 is arranged between the roof 202 and the ceiling 203, one end of the air inlet pipe 103 is located outdoors, and the other end of the air inlet pipe 103 is installed on the heat exchange component, as shown in FIG. Figure 3As shown, the heat exchange component includes a shell 104, and a first partition plate 105 and a second partition plate 106 are arranged perpendicular to each other in the shell 104. The first partition plate 105 and the second partition plate 106 divide the internal space of the shell 104 into four closed areas: upper right, lower right, upper left, and lower left. A heat exchange box 107 is arranged at the intersection of the first partition plate 105 and the second partition plate 106. A plurality of staggered heat exchange tubes 108 are arranged in the heat exchange box 107. The heat exchange tubes 108 are staggered in an oblique manner. The heat exchange tubes 108 in two directions are staggered. 108 are connected to the diagonal areas of the shell 104 formed by the first partition plate 105 and the second partition plate 106, that is, the heat exchange pipe 108 arranged in the oblique upward direction (from left to right) connects the lower left and upper right areas, and the heat exchange pipe 108 arranged obliquely downward connects the upper left and lower right areas. The end of the air inlet pipe 103 connected to the heat exchange component is located in the lower right area. A support column 109 is provided at the lower end of the shell 104, and an exhaust pipe 102 and a fresh air pipe 101 are also provided on the shell 104. The outer wall of the shell 104 is also provided with an exhaust port 11 1. The exhaust port 111 is arranged on the inner wall of the upper right area. The exhaust pipe 102, the air intake pipe 103 and the end of the fresh air pipe 101 are all connected with fans. When in use, the fans at all positions are started. First, the air in the air intake pipe 103 is driven by the fan to transport the air in the external environment to the lower left area in the heat exchange component shell 104, and then enters the fresh air pipe 101 through the heat exchange pipe 108. The fan at the end of the fresh air pipe 101 acts as a relay fan to accelerate the flow of air, and the outside air enters the pig house main body 201 from the fresh air pipe 101. In the indoor environment, small holes can be set on the surface of the exhaust pipe 102. The air around the exhaust pipe 102 enters the exhaust pipe 102 under the action of the fan at its end, and then enters the lower left area of ​​the shell 104 of the heat exchange component, enters the upper left area through the heat exchange pipe 108 in the other direction, and is finally discharged from the exhaust port 111. In winter, the air temperature in the external environment is low and the air temperature in the pig house is high. The two parts of air exchange heat through the heat transfer of the metal heat exchange pipe 108 in the two directions of the heat exchange pipe 108 in the heat exchange box 107.

[0027] By setting up a heat exchange component, the indoor air can be discharged while the indoor air temperature is used to heat the outside cold air entering the room. There is no need to consume additional energy to heat the indoor temperature of the pig house, thus achieving the goal of energy saving and emission reduction.

[0028] Second embodiment:

[0029] like Figure 5As shown, a manure pit is generally provided at the lower end of the pig house main body 201. The manure pit is a direct factor causing air pollution and bacterial infection in the pig house. Therefore, regular cleaning of the manure pit and timely discharge of gases such as ammonia generated in the manure pit can effectively improve the air environment of the pig house. The exhaust pipe 102 is installed on the wall or floor at the upper end of the manure pit. One end of the exhaust pipe 102 is blocked, and a number of holes are equidistantly opened on the lower surface to absorb the dirty gas generated in the manure pit.

[0030] By arranging an exhaust pipe 102 at the upper end of the manure pit, not only can the dirty air in the pig house be absorbed and discharged outdoors, but the temperature of the dirty air can also be used to exchange heat with the absorbed external cold air in the heat exchange component to increase the temperature of the external cold air.

[0031] Third embodiment:

[0032] One end of the fresh air duct 101 is blocked, and a plurality of holes are opened on the surface. A small fan is installed at the holes. When the small fan rotates, the clean air in the fresh air duct 101 can be ejected into the environment in a beam shape, thereby accelerating the flow of air in the fresh air duct 101 and evenly distributing the clean air in the pig house.

[0033] Fourth embodiment:

[0034] The heat exchange box 107 is made of heat-insulating material, such as a sandwich color steel plate, wherein the core material of the color steel plate is a foam board.

[0035] The use of heat-insulating material on the outer wall of the heat exchange box 107 can reduce the temperature loss in the heat exchange box 107 and maintain the temperature in the heat exchange box 107 .

[0036] Fifth embodiment:

[0037] like Figure 3 As shown, adjacent heat exchange tubes 108 are in contact. By staggering and contacting the heat exchange tubes 108, the heat of the hot air can be transferred to the outer wall of the heat exchange tube 108. The outer wall of the heat exchange tube 108 with a higher temperature directly heats the cold air inside it, thereby improving the heating efficiency of the heat exchange component for the air.

[0038] Sixth embodiment:

[0039] like Figure 4-5 As shown, an elbow 110 is provided at one end of the air inlet pipe 103, and the elbow 110 opens downward. One end of the air inlet pipe 103 is located outdoors. The downward elbow 110 can prevent rainwater from entering the air inlet pipe 103 during rainfall and causing corrosion of the air inlet pipe 103, thereby increasing the service life of the air inlet pipe 103.

[0040] Working principle:

[0041] The cold air inhaled from the outside and the hot air exhausted from the room flow through the heat exchange component, and heat exchange occurs inside the heat exchange component. In this way, the hot and dirty air in the room is used to heat the cold air entering the room without affecting the exhaust ventilation, thereby realizing heat recovery and reducing energy consumption.

[0042] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
