Therefore, it is necessary to improve the technical defects in the aforementioned patents. Consequently, we propose a ventilation and humidity regulation device for pig farms. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a ventilation and humidity control device for pig farms.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A ventilation and humidity control device for pig farms includes a pig farm, with a ventilation control device installed on the side of the pig farm. The ventilation control device includes a cooling tank with an arc-shaped bend passing through it. An inner ventilation pipe is fixedly installed at the inner end of the arc-shaped bend, and an outer ventilation pipe is fixedly installed at the outer end of the arc-shaped bend. A duct is installed at the outer end of the outer ventilation pipe. An electric heating wire is installed on the inner wall of the duct. An internal motor is installed inside the duct. An installation disc is fixedly installed on the output end of the internal motor. Several fan blades are evenly distributed on the side of the installation disc. A condensate drain pipe is connected to the bottom of the arc-shaped bend.

[0008] Furthermore, the pig farm is equipped with a temperature and humidity display device.

[0009] Furthermore, the internal ventilation duct extends into the interior of the pig farm.

[0010] Furthermore, a bracket is fixedly installed at the bottom of the cooling tank.

[0011] Furthermore, a water-collecting cone is fixedly installed on the upper side of the cooling tank, and a filter cone cover is provided on the upper end of the water-collecting cone.

[0012] Furthermore, the condensate outlet pipe passes through to the bottom of the cooling tank, and a water receiving tray is provided on the lower side of the condensate outlet pipe port. Several round rods are fixedly connected between the water receiving tray and the outer wall of the condensate outlet pipe.

[0013] Furthermore, the upper port of the water receiving pan is higher than the lower port of the condensate outlet pipe.

[0014] Furthermore, a number of connecting rods are fixedly connected between the built-in motor and the air duct, and a filter cover is screwed onto the outer end of the air duct.

[0016] Compared with related technologies, the ventilation and humidity control device for pig farms proposed in this utility model has the following beneficial effects:

[0017] In this utility model, a ventilation and humidity control device for pig farms is described. The built-in motor in the ventilation duct serves as the power drive component, rotating the fan blades to draw air in. Outside air enters the pig farm through the ventilation duct, external ventilation pipe, curved pipe, and internal ventilation duct, promoting air circulation. Pig farms are generally quite humid due to the feeding habits of pigs, which easily leads to mold and bacterial infections. To reduce humidity, an electric heating wire is activated in the air inlet duct to heat the incoming air. As the air passes through the curved pipe, the water vapor inside condenses upon contact with the cooler pipe, forming water droplets that condense on the inner wall of the curved pipe. This condensate is then discharged through the condensate drain pipe, significantly reducing the moisture content in the ventilated air and effectively dehumidifying the pig farm.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Reference Figure 1-6 A ventilation and humidity control device for pig farms includes a pig farm 1, with a ventilation control device 2 installed on the side of the pig farm 1. The ventilation control device 2 includes a cooling trough 22, through which an arc-shaped bend 25 passes. An inner ventilation pipe 26 is fixedly installed at the inner end of the arc-shaped bend 25, and an outer ventilation pipe 27 is fixedly installed at the outer end of the arc-shaped bend 25. A wind duct 28 is installed at the outer end of the outer ventilation pipe 27. An electric heating wire 213 is installed on the inner wall of the wind duct 28. An internal motor 215 is installed inside the wind duct 28. An installation disc 216 is fixedly installed on the output end of the internal motor 215. Several fan blades 217 are evenly distributed on the side of the installation disc 216. A condensate outlet pipe 210 is connected to the bottom of the arc-shaped bend 25. The inner ventilation pipe 26 passes through the interior of the pig farm 1.

[0027] In this method, the condensate outlet pipe 210 passes through to the bottom of the cooling tank 22 and a water receiving tray 212 is provided on the lower side of the condensate outlet pipe 210 port. Several round rods 211 are fixedly connected between the water receiving tray 212 and the outer wall of the condensate outlet pipe 210.

[0028] With the above-mentioned configuration, the condensate outlet pipe 210 can discharge the condensate collected in the wall of the arc-shaped bend pipe 25 to the outside, so that the condensate is discharged into the water receiving pan 212, and finally overflows from the upper port of the water receiving pan 212.

[0029] In this configuration, the upper port of the water receiving pan 212 is higher than the lower port of the condensate outlet pipe 210.

[0030] With the above-mentioned arrangement, the upper port of the water receiving pan 212 is higher than the lower port of the condensate outlet pipe 210, thus ensuring that the water receiving pan 212 always has a water-collecting function. The condensate discharged from the condensate outlet pipe 210 eventually overflows from the upper side of the water receiving pan, thereby sealing the port of the condensate outlet pipe 210 with the condensate, so that no air is emitted from the condensate outlet pipe 210 during daily ventilation.

[0031] In this configuration, a number of connecting rods 214 are fixedly connected between the built-in motor 215 and the air duct 28, and a filter cover 218 is screwed onto the outer end of the air duct 28.

[0032] With the above configuration, the connecting rod 214 provides a fixed connection point for the built-in motor 215 at the air duct 28.

[0033] In this configuration, flanges 29 are fixedly installed on the right side of the external ventilation duct 27 and the left side of the air duct 28, and the two flanges 29 are screwed together.

[0034] With the above-mentioned setup, the air duct 28 can be removed from the right side of the external ventilation pipe 27. Since the air duct 28 is equipped with two electrical components, namely the heating wire 213 and the built-in motor 215, it facilitates subsequent inspection and maintenance.

[0035] In this method, a temperature and humidity display device is installed in the indoor pig farm 1.

[0036] With the above settings, the temperature and humidity display is used to display the temperature and humidity inside the pig breeding house 1.

[0037] In this method, a bracket 21 is fixedly installed at the bottom of the cooling tank 22.

[0038] With the above-described configuration, the bracket 21 provides support for the cooling tank 22.

[0039] In this method, a water collection cone 23 is fixedly installed on the upper side of the cooling tank 22, and a filter cone cover 24 is provided on the upper end of the water collection cone 23.

[0040] With the above-mentioned configuration, the water collection cone 23 is used to collect rainwater in daily use, which improves the utilization rate of water resources. The filter cone 24 prevents debris from falling into the water collection cone 23 when collecting rainwater.

[0041] The working principle of the ventilation and humidity control device for pig farms provided by this utility model is as follows:

[0042] During use, the built-in motor 215 can be turned on to drive the fan blades 217 to rotate during daily ventilation, thereby drawing outside air into the pig farm 1 through the air duct 28, external ventilation pipe 27, arc-shaped bend 25, and internal ventilation pipe 26, promoting air circulation inside the pig farm 1. When the temperature and humidity display shows that the air inside the pig farm 1 is relatively humid, the heating wire 213 inside the air duct 28 is turned on at the same time as ventilation and exhaust to heat the air flowing into the pig farm 1 from the outside, increasing the activity of water vapor molecules inside. Since the outer wall of the arc-shaped bend 25 is immersed in the cooling tank 22, its pipe wall temperature is low. Therefore, when the air passes through the arc-shaped bend 25, the water vapor in the air comes into contact with the low-temperature pipe wall of the arc-shaped bend 25 to form condensate. Subsequently, the condensate accumulates and is discharged through the condensate outlet pipe 210, greatly reducing the water content in the ventilated air, thereby achieving the function of dehumidifying the pig farm 1.

[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
