Description

Technical Field

[0001] The utility model relates to the technical field of animal husbandry facilities, in particular to a livestock and poultry house with a diffuse ventilation mode. Background Art

[0002] Currently, pig farming remains the leading sector of my country's livestock industry, and pork still dominates the meat consumption structure, accounting for approximately 67%. With economic development and rising consumer spending, people are increasingly pursuing health and longevity. Consequently, the market demand for pollution-free, safe, and green food is growing year by year. Traditional pig farming methods inevitably leave additives and drug residues, leading to frequent animal diseases and posing a serious threat to human health. Pigs require a suitable temperature for growth, and poor ventilation during the breeding process often affects their growth and health. Currently, piggery ventilation is primarily divided into natural and mechanical ventilation. Natural ventilation has disadvantages: during winter, when temperatures are low, cold air enters the shed without preheating, creating drafts that blow onto the pigs, causing them to catch colds. Furthermore, ventilation is ineffective during higher summer temperatures. Currently, mechanical ventilation methods, including positive and negative pressure, have drawbacks, such as high equipment installation costs, high energy consumption, ineffective cooling during hot summer months, and difficulty controlling drafts in winter, which can exacerbate cold stress in pigs. In addition, there are still loopholes in many details. For example, ammonia at the bottom of the manure ditch diffuses into the pig pen, and the fan cannot effectively remove the ammonia at the bottom of the manure ditch in the pig house. The overall growth environment in the pig house is not good, which has a certain impact on some pigs and even workers, and is harmful to their health. Utility Model Content

[0003] The purpose of this utility model is to solve the deficiencies of the above-mentioned existing background technology and to provide a livestock and poultry house with a diffuse ventilation mode to solve the problems of ventilation and cooling uniformity and demand in pig houses in all seasons.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a livestock and poultry house with a diffuse ventilation mode, comprising a livestock and poultry house body, wherein the interior of the livestock and poultry house body is provided with a suspended ceiling, a feeding pen and a manure ditch under the feeding pen, wherein the suspended ceiling board is made of porous material; a corridor is provided outside the air inlet end of the livestock and poultry house body, and a loft is provided above the corridor, and a heat dissipation fin tube is installed in the loft; a first-level air inlet is provided on the outer wall of the loft, a wet curtain is hung on the outside of the first-level air inlet, and a positive pressure fan is installed on the wall between the loft and the suspended ceiling; ventilation windows are provided on the outer wall of the corridor and the two end walls of the livestock and poultry house body; a trench fan is installed on the outer wall of the end of the manure ditch away from the corridor, which is used to extract the dirty gas in the manure ditch out of the house.

[0005] Furthermore, the horizontal installation height of the ceiling board in the suspended ceiling is higher than the installation height of the bottom plate of the attic above the corridor; and the installation height of the heat dissipation fin tube in the attic is lower than the installation position of the positive pressure fan.

[0006] Furthermore, a roller blind for controlling opening and closing is installed on the outer side of the wet curtain of the first-level air inlet, and the roller blind can be rolled up.

[0007] Furthermore, the ventilation window is equipped with a sliding window or a shutter.

[0008] Furthermore, when in winter ventilation mode, the ventilation windows are closed, and fresh air enters the attic through the wet curtain and the first-level air inlet, is preheated by the internal heat dissipation fin tubes, and then blown to the inside of the ceiling by the positive pressure fan, and then evenly enters the breeding area through the porous ceiling panel and falls to the ground; the dirty air is squeezed into the manure ditch through the manure discharge slatted plate, and then discharged out of the house by the ditch fan at the outer end of the manure ditch.

[0009] Furthermore, when in the transition season ventilation mode, natural ventilation is performed, the roller blinds outside the primary air inlet are closed, all ventilation windows are opened, and fresh air directly enters the breeding area through the ventilation windows and is discharged.

[0023] The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings:

[0024] like Figures 1 to 3As shown, a livestock and poultry house with a diffuse ventilation mode is mainly used in the structure of livestock and poultry houses in buildings, and can also be used in bungalow-type livestock and poultry houses. It includes a livestock and poultry house body 1. The interior of the livestock and poultry house body 1 is provided with a suspended ceiling 11, a feeding pen 13 and a manure ditch 14 below the feeding pen 13 from top to bottom. The suspended ceiling 11 and the feeding pen 13 are separated by a suspended ceiling board 12. The suspended ceiling board 12 is made of a porous material and is provided with a plurality of evenly arranged ventilation holes 9; a manure slatted plate is installed between the feeding pen 13 and the manure ditch 14. The livestock house body 1 is provided with a corridor 2 on the outside of the air inlet end. A loft 3 is located above the corridor 2, and a heat dissipation fin tube 4 is fixedly installed inside the loft 3. A first-level air inlet 5 is provided on the outer wall of the loft 3. A retractable wet curtain 6 is mounted on the outer side of the first-level air inlet 5. A roller blind that can be retracted upward is mounted on the outer side of the wet curtain 6. The retraction and extension of the roller blind controls the opening and closing of the first-level air inlet 5. A positive pressure fan 7 is fixedly installed on the wall between the loft 3 and the ceiling 11 to blow fresh air into the ceiling 11. Ventilation windows 8 are provided on the outer wall of the corridor 2, the partition wall between the corridor 2 and the livestock house body 1, and the wall at the end of the livestock house body 1. Sliding windows or blinds are fixedly installed on the ventilation windows 8. At the same time, a trench fan 15 is installed on the outer wall of the manure ditch 14 on the end away from the corridor 2 to extract the dirty air in the manure ditch 14 to the outside of the house.

[0025] The horizontal installation height of the ceiling panel 12 is higher than the installation height of the bottom plate of the attic 3 above the corridor 2; the installation height of the heat dissipation fin tube 5 in the attic 3 is lower than the installation position of the positive pressure fan 7.

[0026] Based on the above livestock and poultry house structure, when in winter ventilation mode, combined with Figure 4 As shown, all ventilation windows 8 are closed, and fresh air enters the attic 3 through the wet curtain 6 and the first-level air inlet 5, then passes through the heat dissipation fin tube 4 installed therein, is preheated by the heat dissipation fin tube 4, and is then blown to the inside of the ceiling 11 by the positive pressure fan 7, and then blown downward through the porous ceiling panel 12 in a diffuse and uniform manner to the feeding pen 13 and falls to the ground; the dirty air is squeezed into the manure ditch 14 through the manure discharge slatted plate, and then discharged to the outside of the house by the trench fan 15 on the outer end side of the manure ditch 14.

[0027] When in transition season ventilation mode, the outside temperature is more suitable, combined with Figure 5 As shown, natural ventilation is selected, the roller blinds outside the primary air inlet 5 are closed downward, all ventilation windows 8 are opened, and fresh air directly enters the feeding pen area through the ventilation windows 8 and is discharged from the other end.

[0028] When in summer ventilation mode, combined with Figure 6As shown, all ventilation windows 8 are closed, and fresh air enters the attic 3 through the wet curtain 6 and the first-level air inlet 5. At this time, the heat dissipation fin tube 4 inside the attic 3 is closed, and the fresh air is directly blown to the inside of the ceiling 11 through the positive pressure fan 7, and then blown downward through the porous ceiling panel 12 in a diffused and uniform manner to the feeding pen 13 and fall to the ground; the dirty air is squeezed into the manure ditch 14 through the manure discharge slatted plate, and then discharged to the outside of the house by the ditch fan 15.

[0029] A further optimized technical solution is that an end wall fan is fixedly installed on the outer side of the wall of the livestock and poultry house body 1 at the end opposite to the corridor 2. When the temperature is high in the transition season ventilation mode, the end wall fan is turned on to increase the ventilation volume.

[0030] The roller shutter outside the above-mentioned first-level air inlet 5 can automatically adjust its opening area according to the temperature, so as to accurately control the air intake and the cooling range of the wet curtain, which is more energy-saving; at the same time, the air volume is increased according to actual production needs to meet the temperature requirements in the feeding pen unit.

[0031] 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.
