Description

Technical Field

[0001] The utility model relates to the technical field of animal husbandry facilities, in particular to an energy-saving piggery with temperature adjustment in stages. Background Art

[0002] Over the past two years, domestic pig prices have continued to decline, while feed prices have continued to rise, resulting in very low profits or even losses for most pig farming companies and farmers. This is undoubtedly exacerbated by the illness and even death of pigs. Pig farming is crucial because pigs have very high requirements for their growth environment, particularly ventilation, temperature, and humidity. However, to reduce costs, most pig houses are relatively simple. Some are open-style greenhouses. While cool and airy in the summer, they are extremely cold in the winter. High summer temperatures can easily lead to heatstroke, which is detrimental to pig growth. Others are enclosed houses. While less cold in the winter, they can be quite hot and stuffy in the summer. Poor ventilation and dry air can easily lead to respiratory and digestive diseases like pneumonia in pigs, which is also detrimental to their growth. With the development of technology, the ventilation conditions of existing house-type pig houses mostly only have two ventilation modes for switching, winter and summer, and the cooling facilities cannot be adjusted in sections; at the same time, the traditional winter ventilation mode has uneven distribution of fresh air, which cannot effectively ventilate the entire pig house, and the internal environment cannot be effectively improved, which greatly increases energy consumption. Utility Model Content

[0003] The purpose of the present invention is to solve the deficiencies of the above-mentioned existing background technology and to provide an energy-saving pig house with temperature adjustment in stages to overcome the problem of a single ventilation mode in the pig house.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: an energy-saving pig house with staged temperature adjustment, comprising a central corridor, a loft located above the central corridor, and pig houses arranged in rows on both sides of the central corridor, wherein the central corridor and the loft above it are an integrated structure with internal communication, and a plurality of first-level air inlets arranged at intervals are provided on the side walls of the loft; a manure ditch is provided at the bottom of each pig house, and an air outlet pipe is arranged above the feeding pen in the pig house, and a plurality of air outlets are provided on the air outlet pipe; An air intake chamber is provided inside the end of the pig house close to the central corridor. The bottom of the air intake chamber is connected to the central corridor through the winter air inlet, and the top of the air intake chamber is connected to the air outlet duct; an end wall fan is installed on the outer wall of the pig house away from the central corridor, which can extract the dirty air in the pig house; multiple roof fans are also installed on the roof of the pig house; multiple secondary air inlets connected to the pig house are provided on the side walls of the central corridor, and the staged temperature control and ventilation function in the pig house is achieved through the mutual opening and closing of the air inlets at each level and the various fans.

[0005] Furthermore, a second wet curtain for cooling is installed at the winter air inlet, and a rolling curtain is hung on the outside of the second wet curtain; a first wet curtain for cooling is hung on the outside of the secondary air inlet, and a rolling curtain is also hung on the outside of the first wet curtain.

[0006] Furthermore, a manure ditch fan is installed on the end side wall of the manure ditch, and when the manure ditch fan is started, the dirty gas in the manure ditch can be sucked out of the house.

[0007] Furthermore, a corresponding air inlet curtain is installed at each first-level air inlet.

[0008] Furthermore, when in winter ventilation mode, the air inlet curtain of the first-level air inlet on the attic is opened, and fresh air enters the central corridor through the first-level air inlet; the air inlet is only opened in winter, the corresponding wet curtain 2 and curtain are rolled up, and fresh air enters the air intake chamber, and then enters the air outlet duct, and enters the pig house from the air outlet on the air outlet duct, replacing the polluted air on the ground; the polluted air is discharged from the pig house through the roof fan or the manure ditch fan.

[0009] Furthermore, when in the transitional season ventilation mode, based on the above-mentioned winter ventilation mode, the secondary air inlet on the side wall of the central corridor is opened, the corresponding wet curtain and roller curtain are rolled up, and then the end wall fan is turned on, and fresh air can directly enter the pig house through the secondary air inlet.

[0010] Furthermore, when in the summer ventilation low temperature mode, based on the above transitional season ventilation mode, the wet curtain 2 at the winter air inlet is opened, and the fresh air enters the pig house after being cooled by the wet curtain.

[0011] Furthermore, when in the summer ventilation high temperature mode, based on the above-mentioned summer ventilation low temperature mode, the wet curtain 1 at the secondary air inlet is opened to further cool the fresh air.

[0012] Compared with the existing technology, the utility model has the following beneficial effects: the utility model has a simple layout and can accurately adjust the ventilation mode according to the seasonal temperature changes outside the house; and the corresponding wet curtain can control the opening area in stages, which makes the cooling more precise and energy-saving.

[0013] This utility model uses a combination of precise air supply and tunnel ventilation, and is applied to pig houses with a loft construction model (the loft can pre-cool and preheat the fresh air). It can provide more uniform fresh air in winter, and the fresh air is further preheated in the underground air chamber, and fresh air is provided to the pig pen through a displacement ventilation mode (fresh air falls vertically to the feeding pen, and the roof fan or the manure ditch fan discharges the dirty air); in the transition season, suitable temperature and comfortable wind speed for pigs are provided by increasing the ventilation volume; in the hot season, while tunnel ventilation, wet curtains can be installed for cooling, and the wind speed near the pigs' bodies can be increased by increasing precise air supply, effectively reducing the perceived temperature (especially in pig houses with solid pens, where the wind speed near the pigs' bodies will be blocked). Compared with traditional tunnel-ventilated pig houses, this mode can reduce costs and save energy; compared with simple precise ventilation modes, this mode can improve the overall environmental comfort in the pig house.

[0025] The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings:

[0026] like Figures 1 to 3As shown, an energy-saving pig house with staged temperature control includes a central corridor 1, a loft 2 located above the central corridor 1, and a row of pig houses 3 arranged on both sides of the central corridor 1, which are arranged symmetrically on both sides. The central corridor 1 and the loft structure above it are an integrated structure with internal communication. A plurality of first-level air inlets 4 arranged at intervals are provided on the left and right side walls of the loft 2, and an air inlet curtain 5 is installed at each first-level air inlet 4 to control the opening and closing of the first-level air inlet 4. A manure ditch 32 is provided at the bottom of each pig house 3 located on both sides of the central corridor 1, and a feeding pen 31 is located above the manure ditch 32. A slatted floor for manure discharge is laid between the two. An air outlet duct 33 is installed above the feeding pen 31, and a plurality of air outlets are arranged evenly along its length on the periphery of the air outlet duct 33. A plurality of roof fans 34 are also installed on the roof of the pig house 3 to exhaust air. An air inlet chamber 7 is provided at the end of the piggery 3 near the central corridor 1. The bottom of the air inlet chamber 7 is connected to the central corridor 1 via a winter air inlet 6, and the top of the air inlet chamber 7 is connected to one end of an air outlet duct 33. Multiple end wall fans 35 are installed on the outer wall of the piggery 3 away from the central corridor 1 to extract the polluted air from the piggery 3. The side walls of the central corridor 1 are provided with secondary air inlets 8 connected to each piggery 3. These are designed in the form of blinds. A retractable cooling wet curtain 10 and a corresponding roller curtain are mounted on the outer side of the secondary air inlet 8. A retractable cooling wet curtain 2 and a corresponding roller curtain are mounted on the outer side of the winter air inlet 6.

[0027] A further optimized technical solution is that a manure ditch fan is installed outside the end wall of the manure ditch 32, and when the manure ditch fan is started, the dirty gas in the manure ditch 32 can be sucked out of the house.

[0028] Based on the above structure, the energy-saving pig house can accurately adjust the temperature in the pig house in stages according to the seasonal temperature changes outside the house. Figure 4 As shown, the air inlet curtain 5 of the first-level air inlet 4 on the attic 2 is opened, and fresh air enters the interior of the central corridor 1 through the first-level air inlet 4; at this time, only the winter air inlet 6 is opened, and the corresponding wet curtain 2 9 and the curtain are rolled up, and the fresh air directly enters the air inlet chamber 7 through the winter air inlet 6, and then enters the air outlet duct 33 from the air inlet chamber 7, enters the pig house 3 from multiple air outlets on the air outlet duct 33, and is blown downward and falls vertically to replace the polluted air on the ground; the polluted air is discharged from the pig house 3 through the roof fan 34 or the manure ditch fan, thereby providing fresh air for the pig pen.

[0029] When in transitional season ventilation mode, combined with Figure 5As shown, based on the above-mentioned winter ventilation mode, the secondary air inlet 8 on the side wall of the central corridor is opened, the corresponding wet curtain 10 and curtain are rolled up, and then the end wall fan 35 is turned on, and the fresh air enters the pig house directly through the secondary air inlet 8, forming a tunnel ventilation mode, increasing the ventilation volume to provide a suitable temperature and comfortable wind speed for pigs.

[0030] When in summer ventilation low temperature mode, combined with Figure 6 As shown, based on the above transitional season ventilation mode, the wet curtain 10 at the secondary air inlet 8 is lowered, and the fresh air enters the pig house 3 after being cooled by the wet curtain.

[0031] When in summer ventilation high temperature mode, combined with Figure 7 As shown, based on the above-mentioned summer ventilation low-temperature mode, the wet curtain 9 outside the winter air inlet 6 is lowered to further cool the fresh air, and the precise air supply is increased through the air outlet, thereby increasing the wind speed near the pig's body and effectively reducing the perceived temperature (especially in a pig house with solid pens, the wind speed near the pig's body will be blocked).

[0032] As a further optimized technical solution, the wet curtain 10 and wet curtain 2 9 are deep water tank wet curtains (with lower opening curtains), which can control their corresponding opening area, thereby accurately controlling the cooling range and saving more energy. The winter air inlet 6 is also equipped with an air filtration system.

[0033] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
