Description

Technical Field

[0001] The invention relates to animal breeding equipment, in particular to a piggery manure odor treatment device. Background Art

[0002] Pig farming is one of the pillar industries of agricultural production and an important way to build a new countryside and increase farmers' income. With the development of pig farming, the discharge of pig manure and urine is also increasing rapidly. Under normal circumstances, a pig's urine volume is larger than its feces volume. A 120-jin pig has an average daily urine volume of about 7 jin and feces volume of about 5 jin. A fattening pig produces about 1.5 tons of feces and urine from birth to market (about 250 jin). Therefore, manure cleaning and subsequent treatment have always been the difficulties of farms. At present, there are three ways to clean manure: water flushing, water soaking, and dry cleaning. Due to cost considerations, most pig farms use the water soaking process to clean manure.

[0003] The main purpose of the water-soaked feces process is to regularly and effectively clear the feces and urine in the pig house, reduce the labor input in the process of feces cleaning, and reduce the water for flushing. Its process flow is to inject a certain amount of water into the manure trough under the slatted floor in the pig house, and the feces, urine, flushing and feeding management water are discharged into the manure trough together, and stored for a certain period of time (generally 1-2 months). After the manure trough is full, the gate of the outlet is opened to discharge the feces and water in the manure trough. However, due to the long-term stay of feces in the pig house, anaerobic fermentation is formed, and a large amount of harmful gases, such as hydrogen sulfide, methane, etc., are produced, which deteriorate the air environment in the house and endanger the health of animals and breeders. At present, most pig farms use a negative pressure ventilation system to discharge the malodorous gases in the pig house outside the pig house to reduce the impact of malodorous gases on humans and animals. Although it can reduce the odor in the pig house to a certain extent, however, since the manure trough is open all day, the odor in the pig house is still serious. Therefore, it is necessary to develop a kind of pig house manure odor treatment device. Summary of the invention

For example, reference can be made to the odor purification box in an indoor farm with adjustable temperature and humidity disclosed in announcement number CN219205510U.

[0039] When the pig house manure odor treatment device is used, first close the sewage valve 37, open the water valve of the water inlet 31 of the manure trough 30 to let water in, so that the water in the manure trough 30 reaches a preset liquid level and then close the water valve. At this time, the water inlet 31 and the first air pipe joint 38 are both located above the liquid level of the manure trough 30. Then, put the first air pipe joint 38 on the first air pipe joint 38, and put the second air pipe joint 39 on the second air pipe joint 39, start the odor purifier 90, and feed the pigs.

[0040] In the initial state, the side of the movable plate 63 close to the fixed plate 61 is inserted into the embedding groove 626, and the side of the movable plate 63 away from the fixed plate 61 is supported on the support plate 621, so that the lower end of the movable plate 63 and the lower end of the fixed plate 61 are close to each other, and the movable plate 63, the fixed plate 61 and the side wall of the manure trough 30 are jointly surrounded to form a roughly V-shaped manure collection space 65, and the manure collection bucket 60 can achieve the seamless state required for storing manure. The manure and urine generated during pig breeding fall into the manure collection space 65 through the slatted floor 23 and are collected. When the preset time is reached, for example, the opening and closing driving member 70 is started at a fixed time every afternoon, and the dual-axis motor 71 drives the two winding wheels 73 to rotate synchronously, and the traction rope 75 is wound around the winding wheel 73, and then the movable plate 63 is pulled to move along the guide groove 620 of the guide frame 62 in the direction away from the fixed plate 61 to form a feces outlet. At this time, the feces collection bucket 60 is opened, and the feces collected in the feces collection bucket 60 flows into the feces soaking tank 30 through the feces outlet. After that, the opening and closing driving member 70 is closed, and the movable plate 63 moves along the guide groove 620 in the direction close to the fixed plate 61 under the action of its own gravity, and the traction rope 75 is pulled to reset until the end of the movable plate 63 away from the support plate 621 is inserted into the embedded groove 626 of the connecting plate 625, that is, the bottom of the feces collection bucket 60 is closed, and the next round of feces collection begins. After the pigs are released from the market, the odor purifier 90 is turned off, the sewage valve 37 is opened, and the sewage pump 51 is started to allow the feces to enter the peripheral manure pool 40 through the sewage pipe 50 and enter the subsequent treatment, cleaning the manure trough 30 and the manure collection bucket 60, and disinfecting them to prepare for the next batch of pigs.

[0041] The above-mentioned pig house manure and sewage odor treatment device is provided with a manure collection bucket 60 for collecting manure and sewage at the top opening of the manure trough 30. When in use, the movable plate 63 and the fixed plate 61 of the manure collection bucket 60 are in a closed state close to each other to reduce the circulation of air between the manure trough 30 and the barn. When the manure and sewage collected in the manure collection bucket 60 is full or reaches a preset time period, the movable plate 63 can be driven by the opening and closing drive member 70 to move in a direction away from the fixed plate 61. At this time, a manure outlet is formed between the lower end of the movable plate 63 and the lower end of the fixed plate 61, so that the manure and sewage in the manure collection bucket 60 falls into the manure trough 30 through the manure outlet. Compared with the traditional open manure trough 30, it can reduce the diffusion of odor generated in the manure trough 30 into the pig house 10, which is beneficial to the health of farmed animals and breeders.

[0042] The above-mentioned pig house manure odor treatment device purifies and discharges the odor continuously generated by the manure stored in the manure trough 30 for a long time and the gas in the stall through the odor purifier 90, further reducing the odor in the pig house and reducing the pollution of the surrounding environment caused by the odor emissions in the pig house.

[0043] The above description is a detailed description of the preferred feasible embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modified changes completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
