Description

Technical Field

[0001] The present invention belongs to the technical field of breeding equipment for livestock and poultry, and particularly relates to a heat recovery device with air filtration. Background Art

[0002] In the field of livestock and poultry breeding, heat recovery devices utilize the heat exchange between the exhaust gas discharged from poultry breeding houses and the fresh air entering the houses, so as to recover the waste heat in the exhaust gas to heat the fresh air, and the purpose of increasing the fresh air supply temperature can be achieved without relying on other heating devices. The waste heat of the exhaust gas that was originally directly discharged outside the house is recovered, and less heating can be achieved during winter breeding in livestock and poultry houses, thus significantly reducing the winter heating load and lowering the heating cost. However, the current heat recovery devices have low heat exchange efficiency for heating fresh air with the waste heat in the exhaust gas, the fresh air temperature rise is low, and the heat recovery effect is poor; the outside fresh air is introduced into the house without filtration, which may contain bacteria, virus, particulate carriers, posing a biosafety hazard, and there will be a lot of dust, feathers and other sundries in the house in the exhaust gas discharged through the heat recovery device, which is extremely easy to block the exhaust outlet of the heat recovery device. If the blockage is serious, it may even cause the device to fail, and manual cleaning is rather cumbersome, requiring frequent replacement of the filtration device, which is time-consuming and laborious. Summary of the Invention

[0019] In order to better understand the purpose, structure and function of the present invention, the heat recovery device with air filtration of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0020] like Figures 1-6 As shown, the present invention is a heat recovery device with air filtration, comprising a warehouse body 1; a heat exchange core 2 is arranged in the warehouse body 1; the heat exchange core 2 is composed of a plurality of heat exchange plates 3 arranged in parallel; a fresh air channel 4 is arranged in the middle of the heat exchange plate 3; an exhaust gas channel 5 is arranged between two adjacent heat exchange plates 3; a fresh air inlet 6 is arranged on one side of the warehouse body 1; the fresh air inlet 6 of the warehouse body 1 is connected with the fresh air channel 4 of the plurality of heat exchange plates 3 of the filter core; a filter module 7 is arranged in the warehouse body 1 at an end of the fresh air channel 4 far away from the fresh air inlet 6 and is relatively connected; an air supply fan 8 is arranged in the warehouse body 1 at a side of the filter module 7 far away from the heat exchange core 2; the air outlet of the air supply fan 8 extends and is connected to the outside of the warehouse body 1; exhaust gas outlets 9 are arranged on both sides of the warehouse body 1 relative to the heat exchange core 2; an exhaust gas exhaust fan 10 is arranged on the upper side of the warehouse body 1 relative to the heat exchange core 2; the exhaust gas outlet 9 is connected with the exhaust gas channel 5 and then connected with the air inlet of the exhaust gas exhaust fan 10.

[0021] Combination Figures 1-6As shown in the figure, when installing this device, connect the fresh air inlet 6 and the air outlet of the exhaust air fan 10 to the natural air outside the poultry house. Set the exhaust air outlet 9 and the air outlet of the supply air fan 8 inside the poultry house. By starting the exhaust air fan 10 and the supply air fan 8, use the exhaust air fan 10 to generate negative pressure in the exhaust air channel 5 of the heat exchange core 2 in the bin, suck the exhaust air in the poultry house through the exhaust air outlet 9, and then discharge it outside the poultry house through the air outlet of the exhaust air fan 10. Use the supply air fan 8 to generate negative pressure in the fresh air channel 4 of the heat exchange core 2 in the bin, suck the natural air outside the poultry house through the fresh air inlet 6, and then introduce it into the fresh air channel 4 through the air outlet of the supply air fan 8. After being filtered by the filter module 7, it is introduced into the poultry house. The fresh air channel 4 through which fresh air passes and the exhaust air channel 5 through which exhaust air passes in the heat exchange core 2 are arranged adjacent to each other in an alternating manner to realize the heat exchange heating of exhaust air to fresh air, increase the fresh air temperature, reduce the heating in the poultry house. The filter module 7 filters the fresh air introduced into the poultry house, prevents particles in the air from entering the poultry house, filters more potential pathogens, such as viruses, bacteria, etc., can effectively prevent the entry of pathogens, and at the same time filtering impurities such as dust and debris in the outside air helps to improve the air quality in the poultry house, helps to provide a good breeding environment, and also avoids cross-contamination caused by air flow between adjacent poultry houses.

[0022] As Figure 6 As shown in the figure, a plurality of metal heat conduction columns 11 are connected between the plurality of heat exchange plates 3. Heat conduction fins 12 are arranged in the fresh air channel 4 of the heat exchange plate 3 and between the exhaust air channels 5 of two adjacent heat exchange plates 3. A heat exchange core 2 is arranged in the bin body 1. The fresh air channel 4 through which fresh air passes and the exhaust air channel 5 through which exhaust air passes in the heat exchange core 2 are arranged adjacent to each other in an alternating manner. At the same time, a plurality of metal heat conduction columns 11 passing through the fresh air channel 4 and the exhaust air channel 5 are provided. Cooperating with the heat conduction fins 12 arranged in the fresh air channel 4 and the exhaust air channel 5 of the metal heat conduction columns 11, using the excellent heat conduction performance of the metal and the large air contact area of the heat conduction fins 12, quickly absorb the heat carried by the exhaust air in the exhaust air channel 5 and conduct it to the fresh air passing through in the fresh air channel 4 to realize efficient heat energy recovery and increase the heat recovery efficiency.

[0023] A rain shield 13 is arranged at the position of the fresh air inlet 6; a filter barrier 14 is arranged at the position of the rain shield 13 opposite to the fresh air inlet 6; the filter barrier 14 is inclined. The filter barrier 14 prevents insects and rodents from entering the bin through the fresh air inlet 6. At the same time, when the supply air fan 8 is started to generate negative pressure on the fresh air inlet 6, filter sundries such as withered leaves and branches driven by the fresh air outside the poultry house to prevent the sundries from entering the bin and blocking the heat exchange core 2. When the supply air fan 8 stops working and no longer generates negative pressure, the sundries such as leaves and branches filtered on the filter barrier 14 will naturally fall under the influence of gravity, preventing the filter barrier 14 from being blocked by sundries after long-term use.

[0024] As Figure 4 shown, the filtration module 7 includes a plurality of plate filters 15 and V-shaped filters 16 which are combined and arranged. The plate filters 15 are used to filter solid particles in the air, and can filter out dust, bacteria, viruses, etc., effectively reducing the concentration of particles in the air. The V-shaped filters 16 are used to filter fine dust particles in the fresh air, further improving the filtration efficiency, increasing the cleanliness of the fresh air introduced into the house, filtering out the vast majority of bacteria and virus particle carriers, effectively reducing the morbidity rate of poultry and livestock, and at the same time reducing the accumulation of particles, protecting key components, and extending the service life of the filtration module 7.

[0025] As Figure 2 shown, there are two sets of guide rollers 17 oppositely arranged at the position of the exhaust gas outlet 9; there are winding wheels 18 rotatably arranged on both sides of the exhaust gas outlet 9; a filter cotton sheet 19 is wound on one winding wheel 18 and passes through between the two sets of guide rollers 17 and then is wound on the other winding wheel 18; a motor 20 is arranged under one winding wheel 18 to drive it to rotate, and one winding wheel 18 is provided with a new filter cotton sheet 19. The filter cotton sheet 19 is arranged at the position of the exhaust gas outlet 9 through between the two sets of guide rollers 17 to filter dust, feathers and other sundries in the exhaust gas discharged from the poultry house, preventing the blockage of the heat exchange core 2. Since there are many sundries such as dust and feathers in the poultry house, after a period of use, the filter cotton sheet 19 filters out a lot of sundries. At this time, the motor 20 is started to rotate the other winding wheel 18 to wind the used filter cotton sheet 19 thereon. While winding the used filter cotton sheet 19, the filter cotton sheet 19 is pulled, and the new filter cotton sheet 19 on the other winding wheel 18 is pulled into the position of the exhaust gas outlet 9 through between the two sets of guide rollers 17, completing the replacement of the filter cotton sheet 19, ensuring that the filtration effect is always in a high state, with high stability and reliability, improving the service life and safety of the equipment. In the case of a large amount of sundries such as dust and feathers in the poultry house and long-term use of this equipment, there is no need for manual frequent replacement or cleaning of the filter cotton sheet, saving labor and time costs.
