Description

Technical Field

[0001] This invention relates to the field of animal husbandry technology, specifically to an SPF animal housing structure based on a fresh air system. Background Technology

[0002] Animals are commonly used as surrogate subjects in life science and medical research, and their use is widespread and extensive. Animal housing used for breeding is the living space of animals, indirectly affecting their growth and development. Currently, most pigsties still adopt traditional methods, using brick walls and roof frames for weight-bearing, with cement floors for easy cleaning. However, this traditional structure has many drawbacks, such as wasting resources, poor insulation in winter, stuffiness in summer, and poor drying.

[0003] To improve this environment, existing pigsties mostly use perforated floors, which facilitates manure discharge, solves the drying problem, and saves resources, requiring only a small amount of water for flushing. Although perforated floors solve some of the problems in animal housing, they still cannot solve the problems of ventilation and cooling in summer and warmth in winter. Summary of the Invention

[0004] The purpose of this invention is to provide an SPF animal housing structure based on a fresh air system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an SPF animal housing structure based on a fresh air system, comprising a housing body, with a first buffer chamber and a second buffer chamber arranged on both sides of the housing body. An air outlet is provided on the outer wall of the first buffer chamber, and a negative pressure fan is installed inside the air outlet. The negative pressure fan draws gas from the direction of the second buffer chamber to the first buffer chamber and discharges it from the air outlet, completing the gas exchange and circulation within the housing body. A water storage tank is provided inside the first buffer chamber to receive water flowing from a water curtain assembly. The water storage tank is connected to the second buffer chamber via a water pipe. A water curtain assembly is installed on the top of the second buffer chamber, and a water inlet pipe is connected to the bottom of the water curtain assembly, and the water inlet pipe is connected to the water inlet pipe, allowing the water to be recycled between the water curtain assembly and the water storage tank, responding to national policies on water conservation. An air inlet is provided on the outer wall of the second buffer chamber, and an exhaust fan is installed inside the air inlet. An exhaust fan draws external air into the building body, allowing air circulation within the building. The bottom of the second buffer chamber has a guide surface with multiple water tanks at its base. Water from the water curtain flows into a storage tank through these tanks, undergoing multiple filtrations at both ends of the tank to ensure recyclability. The water also dissolves odors within the building body, thus purifying the air. A check valve is installed near the storage tank to prevent backflow of water from the storage tank. A protective cover prevents large objects from falling into the tank and contaminating the water. First and second ventilation windows are located on the interfaces between the building body and the first and second buffer chambers, respectively, to facilitate air convection and maintain clean air within the building.

[0006] Preferably, both the air outlet and the air inlet are equipped with filters to filter the outside air and prevent large molecular impurities from entering the building body.

[0007] Preferably, the water storage tank has a drainage hole on its side, and a water guide pipe is installed in the drainage hole.

[0008] Preferably, a water pump is provided at the connection end between the water pipe and the drain hole, and the water in the water storage tank is drawn into the water pipe for diversion by the water pump.

[0009] Preferably, both ends of the water tank are equipped with filter layers to filter and clean the water flowing out of the water curtain assembly so that it can be recycled.

[0010] Preferably, the protective cover is provided with multiple sets of protective nets. The protective nets ensure that the water can come into contact with the air inside the building during the water flow in the water tank, thereby dissolving odors inside the building and achieving the effect of cleaning the air inside the building. At the same time, they prevent large foreign objects inside the building from falling into the water tank and polluting the water.

[0011] Preferably, both the first ventilation window and the second ventilation window are equipped with motorized louvers.

[0012] Preferably, the motorized louvers in the first ventilation window and the second ventilation window are arranged opposite to each other, and the motorized louvers in the first ventilation window and the second ventilation window are tilted towards the first buffer chamber and the second buffer chamber, respectively. This ensures air circulation and isolates large molecular impurities in the first buffer chamber and the second buffer chamber, preventing them from entering the building body and causing damage. The motorized louvers are connected to the main control system via wires.

[0013] Preferably, multiple sets of ventilation windows are provided on the side walls of the building body. When the temperature inside the building body is too high, according to the principle of hot air rising, multiple sets of ventilation windows are provided on the upper part of the side walls of the building body to facilitate the discharge of hot air.

[0014] Preferably, both the negative pressure fan and the exhaust fan are connected to the main control system via wires.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention operates by activating a negative pressure fan, an exhaust fan, and a water curtain assembly. The exhaust fan draws external gas into the building body, and the negative pressure fan draws the gas from the second buffer chamber to the first buffer chamber and discharges it from the air outlet, thus completing the gas exchange and circulation within the building body. When the external gas flows into the second buffer chamber, it is cooled by the water curtain assembly. At the same time, the water curtain assembly can wash the air to ensure the freshness of the air entering the building body. The cooled air flows into the building body, which can replace the gas in the building body, causing the temperature inside the building body to drop. At the same time, the temperature of the gas flowing into the building body can be controlled according to the temperature of the water in the water curtain assembly, thereby maintaining a constant temperature inside the building body. When the temperature inside the building body reaches the required temperature, the temperature inside the building body can be locked by closing the electric louvers.

[0016] Meanwhile, the water from the water curtain system is collected by the guide surface, allowing it to flow into the storage tank through the water trough. As the water flows through the water trough, it permeates the building, keeping the interior environment humid and dissolving odors within the building, thus achieving air purification. Simultaneously, the water flowing at the bottom of the building helps regulate the indoor temperature. Furthermore, the water undergoes multiple filtrations through the filter layers at both ends of the water trough, ensuring the water can be recycled and reused, thus responding to national policies on water conservation.

[0026] Please see Figure 1-5 This invention provides a technical solution: an SPF animal housing structure based on a fresh air system, comprising a housing body 1, with a first buffer chamber 2 and a second buffer chamber 3 arranged on both sides of the housing body 1. An air outlet 4 is provided on the outer wall of the first buffer chamber 2, and a negative pressure fan 6 is installed inside the air outlet 4. The negative pressure fan 6 draws gas from the second buffer chamber 3 to the first buffer chamber 2 and discharges it from the air outlet 4, completing the gas exchange and circulation within the housing body 1. A water storage tank 7 is provided inside the first buffer chamber 2. The water storage tank 7 is used to receive the water flowing out of the water curtain assembly 12. The water storage tank 7 is connected to the second buffer chamber 3 via a water guide pipe 9. The top of the second buffer chamber 3 is equipped with the water curtain assembly 12, and the bottom of the water curtain assembly 12 is connected to a water inlet pipe 11, which is connected to the water guide pipe 9. This allows the water to be recycled between the water curtain assembly 12 and the water storage tank 7, in response to national policies on water conservation. The outer wall of the second buffer chamber 3 is provided with an air inlet 22, and an exhaust fan 23 is installed inside the air inlet 22 to ventilate the outside air. Gas is drawn into the main body of the building 1, allowing air circulation within the building 1. The bottom of the second buffer chamber 3 is equipped with a guide surface 13, and multiple sets of water tanks 14 are installed at the bottom of the guide surface 13. Water from the water curtain assembly 12 flows into the storage tank 7 through the water tanks 14. During the flow, the water undergoes multiple filtrations through the filter layers 15 at both ends of the water tanks 14 to ensure that the water can be recycled. Furthermore, as the water flows through the water tanks 14, it penetrates the main body of the building 1, dissolving odors within the building 1 and thus achieving… The air cleaning effect inside the main body of the building 1 is as follows: A check valve 16 is installed at the end of the water tank 14 near the water storage tank 7 to prevent water in the water storage tank 7 from flowing back into the water tank 14. A protective cover 17 is installed above the water tank 14 to prevent large foreign objects from falling into the water tank 14 and polluting the water. A first ventilation window 19 and a second ventilation window 20 are respectively opened on the interface between the main body of the building 1 and the first buffer room 2 and the second buffer room 3 to facilitate air convection inside the main body of the building 1 and ensure the air cleanliness inside the main body of the building 1.

[0027] Furthermore, both the air outlet 4 and the air inlet 22 are equipped with filters 5 to filter the outside air and prevent large molecular impurities in the outside air from entering the building body 1.

[0028] Furthermore, a drainage hole 8 is provided on the side of the water storage tank 7, and a water guide pipe 9 is installed in the drainage hole 8.

[0029] Furthermore, a water pump 10 is provided at the connection end between the water pipe 9 and the drain hole 8, and the water in the water storage tank 7 is drawn into the water pipe 9 for diversion by the water pump 10.

[0030] Furthermore, filter layers 15 are installed at both ends of the water tank 14 to filter and clean the water flowing out of the water curtain assembly 12 so that it can be recycled.

[0031] Furthermore, the protective cover 17 is provided with multiple sets of protective nets 18. The protective nets 18 ensure that the water can come into contact with the air inside the house body 1 during the flow of water in the water tank 14, thereby dissolving the odor inside the house body 1 and achieving the effect of cleaning the air inside the house body 1. At the same time, they prevent large foreign objects inside the house body 1 from falling into the water tank 14 and polluting the water.

[0032] Furthermore, both the first ventilation window 19 and the second ventilation window 20 are equipped with motorized louvers 21.

[0033] Furthermore, the motorized louvers 21 inside the first ventilation window 19 and the second ventilation window 20 are arranged opposite to each other. The motorized louvers 21 inside the first ventilation window 19 and the second ventilation window 20 are all tilted towards the inner chambers of the first buffer chamber 2 and the second buffer chamber 3, respectively. This ensures air circulation and isolates large molecular impurities in the first buffer chamber 2 and the second buffer chamber 3, preventing them from entering the building body 1 and causing an impact. The motorized louvers 21 are connected to the main control system through wires.

[0034] Furthermore, multiple sets of ventilation windows 24 are provided on the side wall of the building body 1. When the temperature inside the building body 1 is too high, according to the principle of hot air rising, multiple sets of ventilation windows 24 are provided on the upper side wall of the building body 1 to facilitate the discharge of hot air.

[0035] Furthermore, both the negative pressure fan 6 and the exhaust fan 23 are connected to the main control system via wires.

[0036] Working principle:

[0037] In actual use, the negative pressure fan 6, the exhaust fan 23, and the water curtain assembly 12 are started simultaneously. The exhaust fan 23 draws external air into the main body of the building 1, and the negative pressure fan 6 draws the air from the second buffer chamber 3 to the first buffer chamber 2 and discharges it from the air outlet 4, completing the air exchange and circulation within the main body of the building 1. When the external air flows into the second buffer chamber 3, it is cooled by the water curtain assembly 12. At the same time, the water curtain assembly 12 can wash the air to ensure the freshness of the air entering the main body of the building 1. The cooled air flows into the main body of the building 1, which can replace the air in the main body of the building 1, causing the temperature inside the main body of the building 1 to drop. At the same time, the temperature of the air flowing into the main body of the building 1 can be controlled according to the temperature of the water in the water curtain assembly 12, thereby maintaining a constant temperature inside the main body of the building 1.

[0038] Meanwhile, the water in the water curtain group 12 is collected by the guide surface 13, allowing the water to flow into the storage tank 7 through the water tank 14. As the water flows in the water tank 14, it penetrates the building body 1, making the interior environment of the building body 1 humid. The water can dissolve odors in the building body 1, thereby achieving the effect of cleaning the air inside the building body 1. At the same time, the water flows at the bottom of the generator body 1, which can quickly help regulate the indoor temperature of the generator body 1. During the flow, the water is filtered multiple times by the filter layers 15 at both ends of the water tank 14, ensuring that the water can be recycled.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
