Description

Technical Field

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

[0002] Most existing pig farm manure treatment systems use slatted floors with sloping collection troughs at the bottom. These troughs, made of concrete, contain scrapers that periodically scrape pig manure from the higher side to the lower side of the trough before it is discharged into a manure pit for further treatment. This system has three drawbacks: first, the concrete collection troughs are prone to leakage; second, the manure remains in the trough for a long time, resulting in high concentrations of ammonia and hydrogen sulfide in the pigsty, which is detrimental to the health of the pigs; and third, the scrapers are prone to failure due to high humidity and ammonia concentrations in the collection trough, making maintenance inconvenient and increasing labor costs. Furthermore, the process of collecting manure in a manure pit before treatment increases processing costs. Utility Model Content

[0045] 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.

[0046] Please refer to Figures 1 to 5 This utility model provides a pigpen sewage collection device for pig farming, including a collection box 2, a slatted floor 1, a water tank 3, a sewage pipe 4, and a screening and recycling mechanism;

[0047] Multiple collection boxes 2 are provided. The longitudinal section of the collection box 2 is V-shaped. Adjacent collection boxes 2 are connected by a sewage pipe 4 to form a sewage discharge channel.

[0048] The sewage discharge channel is inclined, and the end of the sewage discharge channel is connected to the screening and recycling mechanism through the sewage discharge pipe 7;

[0049] Water tank 3 is connected to collection tank 2 via a drain pipe, and a control valve is installed on the drain pipe.

[0050] The slatted floor 1 is installed at the top opening of the collection box 2;

[0051] When the sewage pipe 4 uses a siphon pipe, when the leftmost collection box 2 needs to be discharged, the control valve opens, and water from the water tank 3 flows into the box. When the water level in the collection box 2 is higher than the upper pipe surface of the sewage pipe 4, the manure in the collection box 2 is discharged to the bottom of the box under the siphon effect. When the water level in the middle collection box 2 is higher than the upper pipe surface of the sewage pipe 4, the manure in that box is discharged to the bottom of the box under the siphon effect and enters the next collection box 2. At this time, each collection box 2 in that section achieves the siphon effect, discharging all the manure in the boxes after that collection box 2 into the sewage pipe 7. 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 discharge quickly. Removing the traditional manure scraping system can reduce maintenance costs and reduce maintenance personnel. With the help of sensors, intelligent sewage discharge and odor removal can be carried out, effectively improving the air quality of the pig house and improving breeding efficiency.

[0052] refer to Figure 6 The second embodiment of this utility model:

[0053] When the sewage pipe 4 is a straight pipe, when the leftmost collection box 2 needs to be discharged, the control valve is opened, and the water in the water tank 3 is flushed into the box. Under the connection of the straight pipe, the sewage in the collection box 2 enters the next collection box 2 directly through the branch pipe. The sewage in the next collection box 2 continues to be discharged with the water flow until it is discharged into the sewage pipe 7.

[0054] refer to Figure 4 and Figure 5 In this embodiment, the collection box 2 includes an upper box body 22 and a lower box body 21. The upper box body 22 has an inner folded edge inside the top opening. The lower box body 21 has an opening at the bottom and an outer folded edge at the bottom that matches the inner folded edge. The lower box body 21 is interlocked with the outer folded edge at the bottom of the upper box body 22 through the inner folded edge. A silicone gasket 23 is installed at the connection between the inner folded edge and the outer folded edge.

[0055] In this application, since there are no joints or seams in the assembly and connection process of the upper box 22 and the lower box 21, it can effectively prevent the leakage of sewage from the upper layer to the lower layer, making it more environmentally friendly and cleaner.

[0056] In this embodiment, the screening and recycling mechanism includes a vibrating screen 8, an extrusion separator 9, a sewage tank 10, and a fecal residue tank 11;

[0057] Sewage pipe 7 connects to vibrating screen 8;

[0058] The discharge port of the vibrating screen 8 is connected to the sewage tank 10, and the slag discharge port of the vibrating screen 8 is connected to the extrusion separator 9.

[0059] The extrusion separator 9 transports the processed manure residue to the manure residue box 11.

[0060] In this embodiment, the collection box 2 is also connected to an exhaust mechanism, which includes an exhaust fan 5, a gas sensor 6, and a PLC controller.

[0061] Gas sensor 6 is installed inside collection box 2;

[0062] The exhaust fan 5 is installed on one side of the collection box 2;

[0063] The exhaust fan 5 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.

[0064] 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.

[0065] The working principle of this utility model is as follows:

[0066] When the leftmost collection box 2 needs to be drained, the control valve opens, and water from the water tank 3 flows into the box. When the water level in collection box 2 is higher than the upper surface of the drain pipe 4, the manure in collection box 2 is completely discharged to the bottom of the box under siphon action. When the water level in the middle collection box 2 is higher than the upper surface of the drain pipe 4, the manure in that box is completely discharged to the bottom of the box under siphon action and enters the next collection box 2. At this time, each collection box 2 at the rear of that collection box 2 achieves a siphon effect, discharging all the manure in the boxes after that collection box 2 into the drain pipe 7. 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 fast drainage. Removing the traditional manure scraping system can reduce maintenance costs and reduce maintenance personnel. With the help of sensors, intelligent drainage and odor removal can be carried out, effectively improving the air quality of the pigsty and improving breeding efficiency.

[0067] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.
