Description

Technical Field

[0001] This utility model belongs to the technical field of fresh air exchange devices, and particularly relates to a fresh air exchange device for aquaculture farms. Background Technology

[0002] In large-scale livestock farms, fresh air exchange devices are widely used. For example, in chicken and pig farms, installing fresh air exchange devices can effectively reduce the concentration of harmful gases in chicken and pig houses, improve air quality, and thus promote the healthy growth of animals.

[0003] In practical applications, when using fresh air exchange devices to purify and ventilate indoor air in farms, these devices typically filter outdoor air before introducing it into the room and expel polluted indoor air. However, in cold winters, this practice leads to a rapid drop in indoor temperature because cold outdoor air is introduced into the room while precious indoor heating is expelled. This not only increases the heating burden but also forces indoor heating equipment to increase its power consumption to maintain the temperature, resulting in unnecessary energy waste. Utility Model Content

[0004] To address the technical problem that existing fresh air ventilation devices waste a significant amount of indoor heating energy during winter use, resulting in unnecessary energy waste, this utility model provides a fresh air ventilation device for livestock farms.

[0005] This utility model is implemented as follows: a fresh air exchange device for a livestock farm, comprising: a shell installed on the wall of the livestock farm, a heat-conducting pipe for drawing air fixedly installed on the shell, and a cavity for exchanging heat in the gas on the heat-conducting pipe; a first fan disposed inside the shell, the air intake end of the first fan being fixedly connected to one end of the heat-conducting pipe, and an exhaust pipe for discharging gas into the room fixedly installed on the exhaust end of the first fan, one end of the exhaust pipe extending to the outside of the shell; an exhaust mechanism installed on the shell for discharging indoor gas; a filter mechanism assembled on the shell for purifying gas; and a spraying mechanism disposed on the shell for spraying pesticides into the gas.

[0012] Compared with related technologies, the fresh air exchange device for livestock farms provided by this utility model has the following beneficial effects:

[0013] This solution utilizes a first fan, heat pipes, and an exhaust pipe to introduce fresh outdoor air into the farm. Simultaneously, an exhaust system expels polluted air from the farm, achieving ventilation. The exhaust system includes a first solenoid valve and a second solenoid valve. In hot weather, the first solenoid valve is opened and the second solenoid valve is closed to prevent the indoor temperature from affecting the heat pipe's temperature. In cold weather, the second solenoid valve is opened and the first solenoid valve is closed, allowing indoor air to pass through the heat pipe's cavity before being exhausted outdoors, ensuring proper ventilation. It exchanges heat with the outdoor fresh air in the heat pipe, thereby recovering some of the heating and reducing the drop in indoor temperature. This effectively solves the problem of existing fresh air ventilation devices wasting a lot of indoor heating and causing unnecessary energy waste during winter use. The use of the filtration mechanism can purify the air introduced into the farm, ensuring the quality of the air entering the farm. The use of the spraying mechanism can atomize the preventive drugs into tiny particles and spray them evenly into the fresh air. These drugs can be discharged into the farm along with the fresh air in the exhaust pipe.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides a fresh air exchange device for aquaculture farms, such as... Figure 1-4 As shown, the fresh air exchange device for the farm includes: a shell 1 installed on the wall of the farm, a heat-conducting pipe 2 for drawing air fixedly installed on the shell 1, and a cavity 9 for exchanging heat in the gas on the heat-conducting pipe 2; a first fan 3 located inside the shell 1, the air intake end of the first fan 3 being fixedly connected to one end of the heat-conducting pipe 2, and an exhaust pipe 4 for discharging gas into the room fixedly installed on the exhaust end of the first fan 3, one end of the exhaust pipe 4 extending to the outside of the shell 1; an exhaust mechanism installed on the shell 1 for discharging indoor gas; a filter mechanism assembled on the shell 1 for purifying gas; and a spraying mechanism installed on the shell 1 for spraying pesticides into the gas.

[0022] In this scheme, when using this device to ventilate the farm, the first fan 3 is activated. The first fan 3 draws in fresh outdoor air through the heat pipe 2 and then exhausts it into the room through the exhaust pipe 4. This exhaust air is filtered before entering the room, effectively removing impurities and ensuring the quality of the air entering the farm. If medication needs to be added to this air to prevent animal diseases and reduce the risk of illness, a spraying mechanism can be activated simultaneously with the exhaust from the exhaust pipe 4. The spraying mechanism atomizes the medication into fine particles and sprays them evenly into the fresh air, allowing the medication to be discharged into the farm along with the fresh air from the exhaust pipe 4. This method is highly effective. When introducing fresh air into the room… During the ventilation process, the exhaust system needs to be activated to discharge polluted gases from the room to the outside, thereby achieving ventilation in the farm. The exhaust system includes a first solenoid valve and a second solenoid valve. When the weather is hot, the first solenoid valve needs to be opened and the second solenoid valve needs to be closed to prevent the indoor temperature from affecting the temperature of the heat pipe 2. When the weather is cold, the second solenoid valve needs to be opened and the first solenoid valve needs to be closed, so that the indoor gas can pass through the cavity 9 of the heat pipe 2 before being discharged to the outside. This allows the gas discharged from the room to exchange heat with the fresh outdoor air in the heat pipe 2, thereby recovering some of the heating and reducing the drop in indoor temperature. This effectively solves the problem that existing fresh air ventilation devices waste a lot of indoor heating in winter, causing unnecessary energy waste.

[0023] In a further preferred embodiment of this utility model, the exhaust mechanism includes: a second fan 5 disposed within the housing 1, with an exhaust pipe 6 for drawing indoor gas fixedly installed on the air inlet end of the second fan 5; a connecting pipe 7 fixedly installed on the housing 1, one end of the connecting pipe 7 being fixedly connected to the exhaust end of the second fan 5, and a first solenoid valve being provided on the connecting pipe 7; a through pipe 8 fixedly installed on the connecting pipe 7, the top end of the through pipe 8 being fixedly connected to the heat-conducting pipe 2, the through pipe 8 communicating with the interior of the cavity 9, and a second solenoid valve being provided on the through pipe 8; and an exhaust pipe 10 fixedly installed on the housing 1, the bottom end of the exhaust pipe 10 being fixedly connected to the heat-conducting pipe 2, and the exhaust pipe 10 communicating with the interior of the cavity 9.

[0024] In this embodiment, the exhaust mechanism is used to exhaust indoor gas. When used in hot weather, the first solenoid valve is opened and the second solenoid valve is closed, and the second fan 5 is started. The second fan 5 will transport the gas in the breeding farm to the connecting pipe 7 through the exhaust pipe 6, and then exhaust it to the outside from one end of the connecting pipe 7. When used in cold weather, the second solenoid valve is opened and the first solenoid valve is closed, so that the gas entering the connecting pipe 7 can enter the through pipe 8. The through pipe 8 will transport the gas in the breeding farm to the cavity 9, and finally exhaust it from the exhaust pipe 10. This can transfer the temperature of the gas in the breeding farm to the heat-conducting pipe 2, so that the heat-conducting pipe 2 can transfer heat to the fresh air in the heat-conducting pipe 2. The gas exhausted from the room can exchange heat with the fresh outdoor air in the heat-conducting pipe 2, thereby recovering some of the heating and reducing the drop in indoor temperature. This effectively solves the problem that existing fresh air ventilation devices waste a lot of indoor heating and cause unnecessary energy waste when used in winter.

[0025] In a further preferred embodiment of the present invention, the filtering mechanism includes: a frame plate 11 fixedly mounted on the housing 1, the bottom of the frame plate 11 having an installation opening, an installation plate 12 being provided on the installation opening, the installation plate 12 having a plurality of through holes, bolts being slidably mounted on the plurality of through holes, and the plurality of bolts being threadedly connected to the bottom of the frame plate 11; and filter screens 13 symmetrically arranged on the installation plate 12 for blocking impurities.

[0026] In this embodiment, the filtration mechanism is used to purify the gas. During the process of the heat pipe 2 drawing in outdoor air, outdoor gas is continuously introduced into the frame plate 11. The gas entering the frame plate 11 is filtered by multiple layers of filter screen 13, which effectively removes impurities from the gas. In this way, the gas that finally enters the heat pipe 2 is relatively clean, and the purification effect is good.

[0027] In a further preferred embodiment of the present invention, the spraying mechanism includes: a medicine tank 14 fixedly installed on one side of the housing 1; a water pump 15 fixedly installed on the inner wall of the bottom of the medicine tank 14, a drain pipe 16 fixedly installed on the drain end of the water pump 15, the top end of the drain pipe 16 extending into the interior of the exhaust pipe 4, and an atomizing nozzle 17 for spraying medicine fixedly installed on the top end of the drain pipe 16.

[0028] In this embodiment, the spraying mechanism is used to spray preventive drugs onto the gas. When in use, the water pump 15 is started, and the water pump 15 draws the drugs in the medicine tank 14 into the drain pipe 16. Finally, the atomizing nozzle 17 sprays out the drugs, which can atomize the preventive drugs into tiny particles and spray them evenly into the fresh air. This allows the drugs to be discharged into the farm along with the fresh air in the exhaust pipe 4. In this way, the drugs can be dispersed by the gas as needed, which can prevent animal diseases and reduce the risk of animal diseases.

[0029] In a further preferred embodiment of the present invention, a water inlet pipe for adding preventive and therapeutic drugs is fixedly installed on the top of the medicine box 14, and a cover is threaded onto the water inlet pipe.

[0030] In this embodiment, the use of a water inlet pipe allows staff to easily add medications for preventing animal diseases into the medicine box 14. The use of a cover allows staff to easily cover the water inlet pipe to prevent impurities in the air from entering the medicine box 14 through the water inlet pipe.

[0031] In a further preferred embodiment of the present invention, an observation port is provided on one side of the medicine box 14, and an observation window 18 is fixedly installed on the inner wall of the observation port.

[0032] In this embodiment, by using the observation window 18, the remaining amount and status of the medicine in the medicine box 14 can be known at any time without opening the lid, thereby avoiding the inconvenience and possible contamination risk caused by frequently opening the lid.

[0033] In a further preferred embodiment of the present invention, a shielding plate is fixedly installed on one side of the frame plate 11, and the shielding plate is used to block rainwater.

[0034] In this embodiment, the main function of the baffle is to block rainwater and prevent it from entering the filter mechanism, thereby protecting key components such as the filter screen 13 from damage.

[0035] In summary, compared with related technologies, this solution, through the coordinated use of the first fan 3, heat pipe 2, and exhaust pipe 4, can introduce fresh outdoor air into the farm. Simultaneously, an exhaust system can discharge polluted indoor air to the outside, thus achieving ventilation within the farm. The exhaust system includes a first solenoid valve and a second solenoid valve. In hot weather, the first solenoid valve must be opened and the second solenoid valve closed to prevent the indoor temperature from affecting the temperature of the heat pipe 2. In cold weather, the second solenoid valve must be opened and the first solenoid valve closed, allowing indoor air to pass through the cavity 9 of the heat pipe 2 before being exhausted outdoors. The exhaust gas from the room can exchange heat with the fresh outdoor air in the heat pipe 2, thereby recovering some of the heating and reducing the drop in indoor temperature. This effectively solves the problem of existing fresh air ventilation devices wasting a lot of indoor heating and causing unnecessary energy waste during winter. The use of the filtration mechanism can purify the gas introduced into the farm, ensuring the quality of the air entering the farm. The use of the spraying mechanism can atomize the preventive drugs into tiny particles and spray them evenly into the fresh air, so that these drugs can be discharged into the farm along with the fresh air in the exhaust pipe 4. In this way, the gas can be used to spread the drugs as needed, which can prevent animal diseases and reduce the risk of animal diseases.
