Description

Technical Field

[0001] The utility model relates to the technical field of pigsty ventilation, and particularly relates to an environment-friendly pigsty ventilation device. Background Art

[0002] A pigsty is a building for raising pigs. According to different feeding purposes, it can be divided into breeding pigsty, pregnant pigsty, farrowing pigsty, growing pigsty, fattening pigsty, etc. Feeding and drinking water are generally carried out inside the pigsty, and there is a sports ground or manure passage for the pigs outside the pigsty. The inside of the pigsty is separated by partition walls or fences. Good ventilation can timely discharge the harmful gases generated in the pigsty, reduce the irritation and damage to the respiratory tract of pigs; in addition, since pigs are more sensitive to temperature, ventilation helps to adjust the temperature in the pigsty. In the hot summer, ventilation can take away heat, reduce the temperature of the pigsty, and prevent pigs from suffering heatstroke.

[0003] The existing pigsty ventilation is usually set separately, and the air inlet and outlet are independent of each other without interference. In summer, the air inside the pigsty is cooler than the outside, and in winter, the air inside the pigsty is warmer than the outside. As a result, when the outside wind enters the pigsty, it needs to be adjusted by the air conditioner to adapt to the temperature of the pigs, resulting in high energy consumption and increasing the breeding cost of live pigs. Content of the Utility Model

[0004] The purpose of the utility model is to provide an environment-friendly pigsty ventilation device to solve the above deficiencies in the prior art.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An environment-friendly pigsty ventilation device includes an air inlet pipe and an air outlet pipe, and both the air inlet pipe and the air outlet pipe are communicated with a heat exchanger; the heat exchanger includes a housing connected to the air inlet pipe and the air outlet pipe, and a plurality of air inlet channels are arranged in the housing. The adjacent air inlet channels form an air outlet channel. The air inlet pipe is communicated with the air inlet channel, and the air outlet channel is communicated with the air outlet channel.

[0007] Further, the air inlet channel is arranged in an L shape.

[0008] Further, the air inlet channel is arranged in multiple bends along the movement direction of the wind, and the directions of adjacent bends are opposite.

[0009] Further, the air inlet pipe and the air outlet pipe are arranged vertically.

[0010] Further, a wind guiding block is fixedly arranged at the inlet of the air outlet pipe in the air outlet duct, and the wind guiding block is arranged in a conical shape.

[0011] In the above technical solution, the beneficial effects of the environment-friendly pigsty ventilation device provided by the utility model are as follows:

[0012] Through the provided heat exchanger, the external wind enters the pigsty through the air inlet pipe, and the wind in the pigsty is discharged from the pigsty through the air outlet pipe. When the external wind enters the air inlet channel, it exchanges heat with the wind discharged from the pigsty in the adjacent air outlet channel, thereby pre-treating the temperature of the external wind. That is, in summer, the wind in the pigsty preliminarily cools the external wind; in winter, the wind in the pigsty preliminarily warms the external wind. The utility model utilizes the wind discharged from the pigsty to pre-treat the temperature of the external wind, reduces the temperature difference of air-conditioning temperature control, and further improves the level of green and environment-friendly pig breeding.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0023] Please refer to Figures 1-4 , an environment-friendly pigsty ventilation device, including an air inlet pipe 1 and an air outlet pipe 2, both the air inlet pipe 1 and the air outlet pipe 2 are communicated with a heat exchanger 3; the heat exchanger 3 includes a housing 31 connected to the air inlet pipe 1 and the air outlet pipe 2, and a plurality of air inlet channels 32 are provided in the housing 31, and adjacent air inlet channels 32 form an air outlet channel 33, the air inlet pipe 1 is communicated with the air inlet channel 32, and the air outlet channel 33 is communicated with the air outlet channel 33.

[0024] Through the provided heat exchanger 3, the outside air enters the pigsty through the air inlet pipe 1, and the air in the pigsty is discharged from the pigsty through the air outlet pipe 2. When the outside air enters the air inlet channel 32, it exchanges heat with the air discharged from the pigsty in the adjacent air outlet channel 33, thereby performing temperature pretreatment on the outside air. That is, in summer, the air in the pigsty preliminarily cools the outside air; in winter, the air in the pigsty preliminarily warms the outside air. The utility model utilizes the air discharged from the pigsty to perform temperature pretreatment on the outside air, reduces the temperature difference of air conditioning temperature control, and further improves the level of green and environment-friendly pig breeding.

[0025] Further, the air inlet channel 32 is arranged in an L shape. The L-shaped arrangement of the air inlet channel 32 effectively extends the movement path of the outside air in the heat exchanger 3, enabling the air discharged from the pigsty in the air outlet channel 33 to exchange heat with it.

[0026] Further, the air inlet channel 32 is arranged in multiple bends along the movement direction of the air, and the directions of adjacent bends are opposite. The multiple-bend arrangement further improves the movement path of the outside air, further increases the time of heat exchange, and further improves the effect of temperature pretreatment.

[0027] Further, the air inlet pipe 1 and the air outlet pipe 2 are arranged vertically. The air inlet pipe 1 and the air outlet pipe 2 of the utility model are more suitable for installation at the corner of the pigsty, so that the outside air entering through the air inlet pipe 1 and the outside air discharged through the air outlet pipe 2 do not affect each other, avoiding the discharged air in the pigsty from entering the pigsty through the air inlet pipe 1 and affecting the health of pigs.

[0028] Further, a wind guiding block 34 is fixedly arranged at the inlet of the air outlet duct 2 of the air outlet duct 2, and the wind guiding block 34 is arranged in a conical shape. The wind guiding block 34 is used to guide the air in the pigsty into the air outlet channel 33, which can increase the movement speed of the air in the pigsty, thereby improving the heat exchange effect.

[0029] Working principle: When the outside air enters the air inlet channel 32, it exchanges heat with the air discharged from the pigsty in the adjacent air outlet channel 33. The L-shaped design and multi-segment bending design of the air inlet channel 32 further improve the heat exchange effect, thereby effectively pre-treating the temperature of the outside air. That is, in summer, the air in the pigsty preliminarily cools the outside air; in winter, the air in the pigsty preliminarily warms the outside air. The utility model uses the air discharged from the pigsty to pre-treat the temperature of the outside air, reduces the temperature difference of air conditioning temperature control, and further improves the green and environment-friendly pig breeding water

[0030] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
