Description

Technical Field

[0001] This utility model relates to the technical field of livestock and poultry breeding equipment, specifically to a heat recovery device for multi-story pigsties. Background Technology

[0002] In the field of pig farming, the temperature requirements for pig houses are relatively high, so temperature control of pig houses is very important. In summer, ventilation can be used to cool down the pig houses, but in winter, heating equipment is generally used to raise the temperature inside the pig houses. However, even in winter, ventilation is still required inside the pig houses. The ventilation process may cause the temperature inside the pig houses to drop, so the heating temperature needs to be increased, which increases the farming cost.

[0003] To address the aforementioned issues, existing technologies have proposed heat recovery equipment that utilizes waste gas emitted from the livestock shed to exchange heat with incoming fresh air. This recovers the waste heat from the waste gas to heat the fresh air, achieving the goal of increasing the fresh air supply temperature without the need for other heating equipment. The heat energy from the waste gas that was previously directly emitted outside the shed is now recovered, enabling livestock sheds to require minimal or no heating during winter, thus significantly reducing the winter heating load and lowering heating costs.

[0004] Existing heat recovery equipment has a complex structure, and its cost is high if used in large quantities in multi-story pig houses, with high subsequent maintenance costs, making it unsuitable for widespread application. Utility Model Content

[0005] To address the aforementioned problems, the main objective of this utility model is to provide a heat recovery device for multi-story pigsties. This heat recovery device has a simple structure, is easy to install, effectively reduces the construction cost of pigsties, and can achieve the purpose of heat recovery of waste gas inside the pigsty, while also achieving the purpose of air exchange and ventilation inside the pigsty.

[0006] To achieve the above objectives, this utility model provides a heat recovery device for multi-story pigsties, including a frame, a housing, a partition, a heat exchanger, an exhaust fan, a blower, and two inspection doors. The housing is located on the upper surface of the frame, and the partition, heat exchanger, exhaust fan, and blower are located inside the housing. The partition is located at the upper end of the heat exchanger and in the middle of the housing. The partition and heat exchanger divide the housing into a first chamber and a second chamber, which are not interconnected. The exhaust fan and blower are located on opposite sides of the heat exchanger, with the blower inside the first chamber and the exhaust fan inside the second chamber.

[0007] Furthermore, the equipment housing is equipped with a fresh air inlet, an air supply outlet, an exhaust outlet, and a waste gas outlet. The fresh air inlet is connected to the first chamber, and the waste gas outlet is connected to the second chamber.

[0008] Furthermore, the inspection doors are located on the left and right sides of the equipment enclosure and are respectively positioned opposite the exhaust fan and the supply fan.

[0009] Furthermore, the equipment enclosure is made of composite insulation board.

[0010] Furthermore, a filter screen is installed on the outside of the fresh air inlet.

[0011] Furthermore, the exhaust vent is connected to the pigsty, and a filter device is installed on the side of the exhaust vent closest to the pigsty. The filter device includes a mounting frame and a metal mesh, an electrostatic fiber adsorption layer, and a carbon adsorption deodorization layer located sequentially on the mounting frame.

[0012] The beneficial effects of this utility model through the above technical solution include:

[0013] (1) The heat recovery equipment used in the multi-story pigsty of this utility model can be installed by directly installing the frame in the multi-story pigsty, which is convenient to install;

[0014] (2) In addition, the heat recovery equipment of this utility model has a simple internal structure. The exhaust fan and the blower work together to exchange the exhaust gas in the pig house with the fresh air outside through the heat exchanger, while also achieving the purpose of ventilation inside the pig house. Moreover, the air volume is large and the working efficiency is high during the exchange of hot and cold air and ventilation. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] like Figure 1 The diagram shows the internal and external structure of the heat recovery equipment used in the multi-story pigsty of this utility model. The heat recovery equipment used in the multi-story pigsty of this utility model includes a frame 1, an equipment box 2, a partition 23, a heat exchanger 3, an exhaust fan 4, a blower 5, and two inspection doors 6. The frame 1 is fixed to the multi-story pigsty. The equipment box 2 is made of composite insulation board and is located on the upper surface of the frame 1. The partition 23, the heat exchanger 3, the exhaust fan 4, and the blower 5 are located inside the equipment box 2. The inspection doors 6 are located on the left and right sides of the equipment box 2 and are respectively opposite to the exhaust fan 4 and the blower 5. The inspection doors 6 facilitate the inspection and maintenance of the exhaust fan 4, the blower 5, or the heat exchanger 3 at any time.

[0025] Specifically, such as Figure 2 and Figure 3 As shown, the heat exchanger 3 is located at the bottom of the equipment housing 2, the partition 23 is located at the top of the heat exchanger 3, the partition 23 and the heat exchanger 3 are located in the middle of the equipment housing 2, and the partition 23 and the heat exchanger 3 divide the equipment housing 2 into a first chamber 21 and a second chamber 22. The first chamber 21 and the second chamber 22 are not connected to each other. The exhaust fan 4 and the supply fan 5 are located on both sides of the heat exchanger 3, the supply fan 5 is located in the first chamber 21, and the exhaust fan 4 is located in the second chamber 22.

[0026] Other examples Figures 1-4 As shown, the equipment housing 2 of this utility model is provided with a fresh air inlet 24, an air supply outlet 25, an exhaust outlet 26 and a waste gas outlet (not shown in the figure). The fresh air inlet 24 is connected to the first chamber 21, and the waste gas outlet is connected to the second chamber 22. In addition, the equipment housing 2 is also provided with a return air outlet 27.

[0027] The structure of the heat exchanger 3 of this utility model is the existing heat exchanger structure. The heat exchanger 3 is provided with a heat source side channel and a heat load side channel. The gas in the two channels exchanges heat. The upstream end of the heat source side channel is connected to the second chamber 22 and the downstream end is connected to the exhaust port. The upstream end of the heat load side channel is connected to the first chamber 21 and the downstream end is connected to the blower 5 or the air outlet 25.

[0028] The working principle of the heat recovery equipment in this utility model for multi-story pigsties is as follows: The heat recovery equipment is installed inside the multi-story pigsty. Since the exhaust vent 26 is connected to the pigsty, the hot exhaust gas inside the pigsty, under the action of the exhaust fan 4, enters the second chamber 22 of the equipment housing 2 through the exhaust vent 26. The hot exhaust gas then enters from the upstream end of the heat source side channel of the heat exchanger 3, exchanges heat with the other heat load side channel, and finally discharges the heat-exchanged exhaust gas through the exhaust vent. Meanwhile, a fresh air ventilation duct is connected to the outside of the fresh air inlet 24 on the other side, and external fresh air enters the first chamber of the equipment housing 2 through the fresh air inlet 24. Within 21, the flow in this process is due to the blower 5 discharging the hot air in the first chamber 22 into the pigsty through the air outlet 25. This creates a pressure difference between the inside and outside of the first chamber 22, allowing fresh air from outside to enter smoothly from the fresh air inlet 24. Subsequently, it enters the upstream end of the heat load side channel in the heat exchanger 3, where it exchanges heat with the hot waste gas in the heat source side channel. As a result, the temperature of the fresh air increases, and finally, it enters the pigsty through the blower 5 and the air outlet 25. This process not only achieves air circulation within the pigsty but also recovers some of the heat from the waste gas to increase the temperature of the fresh air, thereby reducing the heating cost of the pigsty.

[0029] In other preferred embodiments, a filter screen (not shown in the figure) is provided on the outside of the fresh air inlet 24. The filter screen can filter the outside air entering the fresh air inlet 24 to prevent larger particles or pollutants from entering the equipment and affecting the normal operation of each part. In addition, a filter device 7 (such as...) can also be provided on the side of the exhaust vent 26 near the pigsty. Figure 5 As shown), the filter device 7 here is equipped with a mounting frame 71 and a metal mesh 71, an electrostatic fiber adsorption layer and a carbon adsorption deodorization layer located sequentially on the mounting frame. The mounting frame 71 is fixed to the exhaust port 26 by bolts. The filter device 7 can filter the hot exhaust gas in the pig house before it enters the heat recovery equipment, which can keep the equipment box 2, especially the second chamber 22, clean and dry, and improve the service life of the equipment.

[0030] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
