Description

Technical Field

[0001] This utility model relates to the field of pig farming, and in particular to a pigpen sewage discharge device for pig farming. Background Technology

[0002] Most existing pig farms use fully slatted floors with sloping manure collection troughs installed at the bottom. These troughs are made of concrete and contain manure scrapers that periodically scrape pig manure from the higher side of the trough to the lower side before discharging it from the pig farm. This manure collection trough system has several drawbacks: firstly, the concrete troughs are relatively high and expensive; secondly, they are prone to leakage; thirdly, the manure remains in the trough for a long time, resulting in high concentrations of ammonia and hydrogen sulfide in the pig farm, which is detrimental to the health of the pigs; and fourthly, the manure scrapers are prone to failure due to high humidity and ammonia concentrations in the trough, making maintenance inconvenient and increasing labor intensity.

Eliminating the traditional scraping system reduces maintenance costs and personnel. Combined with sensors, intelligent drainage and odor control can be achieved, effectively improving air quality in the pigsty and increasing breeding efficiency. Attached Figure Description

[0036] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Please refer to Figures 1 to 2 This utility model provides a pigpen sewage discharge device for pig farming, including a slatted floor 1, a collection box 2, a water tank 3, and a sewage pipe 8;

[0038] The collection box 2 is fixedly installed at the bottom of the slatted floor 1, the slatted floor 1 is inclined, and the longitudinal section of the collection box 2 is V-shaped;

[0039] The bottom of the collection box 2 is inclined at an angle of D°.

[0040] The water tank 3 is connected to the collection tank 2 via a drain pipe 4, and a control valve 5 is installed on the drain pipe 4;

[0041] One end of the sewage pipe 8 is connected to the collection box 2, and the other end of the sewage pipe 8 is connected to the sewage collection tank;

[0042] In use, pig manure and urine falling from the slatted floor are collected at the bottom of collection box 2 and discharged from collection box 2 by gravity through drain pipe 8. When collection box 2 needs to be flushed, control valve 5 is opened, and water from water tank 3 flows into the box, discharging the manure and waste from collection box 2. When the drain pipe is a siphon pipe, when the water level in the V-shaped groove is higher than the upper surface of the siphon pipe 8, all the manure and waste in the box is discharged to the bottom of the box under the siphon effect. This application has a simple structure, uses a V-shaped long groove structure to save materials, and uses an arc-shaped bottom to prevent dirt accumulation and facilitate rapid sewage discharge. Eliminating the traditional manure scraping system can reduce maintenance costs and the number of maintenance personnel. With the help of sensors, intelligent sewage discharge and odor removal can be achieved, effectively improving the air quality in the pigsty and enhancing breeding efficiency.

[0043] In this embodiment, the bottom of the collection box 2 is arc-shaped with an included angle not exceeding 90°, and the two sides of the opening of the collection box 2 are provided with outwardly extending folded edges.

[0044] In this embodiment, the water tank 3 is equipped with a high water level sensor, a low water level sensor, a controller, a water inlet pipe, and an automatic valve.

[0045] Both the high-level water level sensor and the low-level water level sensor are installed inside the water tank 3. The high-level water level sensor is installed at the highest preset water level inside the water tank 3, and the low-level water level sensor is installed at the lowest preset water level inside the water tank 3.

[0046] The water inlet pipe is connected to the water tank 3, and an automatic valve is installed on the water inlet pipe;

[0047] The high-level water level sensor, the low-level water level sensor, and the automatic valve are all electrically connected to the controller.

[0048] During use, the water level in the water tank 3 is monitored by the high-level water level sensor and the low-level water level sensor. When the water level in the water tank 3 reaches the set water level height, the water intake can be stopped automatically, and when the water level is lower than the set water level height, the water can be replenished automatically.

[0049] In this embodiment, the collection box 2 is also connected to an exhaust mechanism, which includes an exhaust fan 7, a gas sensor 6, and a PLC controller.

[0050] The gas sensor 6 is installed inside the collection box 2;

[0051] The exhaust fan 7 is installed on one side of the collection box 2;

[0052] The exhaust fan 7 and the gas sensor 6 are both electrically connected to the PLC controller. The gas sensor 6 is an ammonia sensor and a hydrogen sulfide sensor.

[0053] When in use, when the gas sensor 6 detects that the concentration of ammonia or hydrogen sulfide in the collection box 2 is higher than the set value (10 mg / m3 for ammonia and 5 mg / m3 for hydrogen sulfide in the example), the fan is started to exhaust the pigsty until the concentration is lower than the set value.

[0054] The working principle of this utility model is as follows:

[0055] Pig manure and urine falling from the slatted floor collect at the bottom of collection box 2 and are discharged from collection box 2 by gravity through drain pipe 8. When collection box 2 needs to be flushed, control valve 5 opens, and water from water tank 3 flows into the box, discharging the manure and waste from collection box 2. When the drain pipe is a siphon pipe, when the water level in the V-shaped trough is higher than the upper surface of the siphon pipe 8, all the manure and waste in the box is discharged to the bottom of the box under the siphon effect. This application has a simple structure, uses a V-shaped long trough structure to save materials, and uses an arc-shaped bottom to prevent dirt accumulation and facilitate rapid sewage discharge. Eliminating the traditional manure scraping system reduces maintenance costs and the number of maintenance personnel. With the help of sensors, intelligent sewage discharge and odor control can be achieved, effectively improving the air quality in the pigsty and enhancing breeding efficiency.
