Description

Technical Field

[0001] The invention relates to livestock and poultry breeding equipment, in particular to a device for treating livestock and poultry manure odor. Background Art

[0002] With the improvement of people's living standards, the strong demand for pork and the need to accelerate economic development in poor areas, pig farming has become one of the pillar industries of rural agriculture. In most rural areas, pig farming is an important source of family income. However, with the increasing scale of farming, the accompanying problem of pig manure and urine disposal has troubled farmers.

[0003] Generally speaking, a pig produces more urine than feces. A 120-pound pig has an average daily urine output of about 7 pounds and feces output of about 5 pounds. A fattening pig produces about 1.5 tons of urine and feces from birth to market (about 250 pounds). Therefore, manure cleaning and subsequent treatment have always been difficult tasks for farms. Currently, there are three ways to clean manure: flushing, soaking, and dry cleaning. Due to cost considerations, most pig farms use the soaking process.

[0004] The manure soaking process refers to the installation of a manure soaking trough for storing manure and sewage for a certain period under the slatted floor of the pig house. A certain amount of water is put in, which can store pig manure and urine for 6 to 12 weeks. During the pig breeding period, the pig manure and urine automatically leak into the manure soaking trough without flushing the pigpen. After the pigs are put on the market or transferred to the pen, the valve is opened to release the manure and sewage, and then comprehensive cleaning and disinfection work is carried out. Generally speaking, a batch of pigs can be cleaned once, which greatly shortens the work of cleaning manure. At the same time, because the breeder does not need to be prepared to clean manure all the time, it will reduce interference to the pigs, which can make the pigs live more comfortably and is more conducive to the health of the pigs.

[0005] The advantage of using the water-soaked manure process is that it saves water compared to the water-flushing manure process. However, the manure trough of the "water-soaked manure" is not cleaned in time. Over time, the organic matter in the manure trough forms anaerobic fermentation, producing a large amount of harmful gases, such as ammonia, H2S (hydrogen sulfide), CH4 (methane), methylamine, skatole and other malodorous gases. In order to reduce the impact of malodorous gases on humans and animals, most pig farms use a negative pressure ventilation system to discharge the malodorous gases in the pig house to the outside of the pig house. Although it can reduce the odor in the house to a certain extent, the manure trough is open all day long. The feces and urine in the manure trough continue to produce odor under the continuous action of micro-computer organisms, and the odor in the house is still serious. At the same time, the negative pressure ventilation system is used to discharge the malodorous gases in the pig house to the outside of the pig house, which causes serious pollution to the surrounding environment. In order to solve this problem, it is urgent to explore an environmentally friendly breeding odor treatment technology. Therefore, it is necessary to develop a livestock and poultry manure odor treatment device. Summary of the invention

The mounting seat 624 is fixed to the bottom surface of the plate body 621 of the movable plate 62 , and the mounting shaft 625 passes through the mounting seat 624 .

[0037] In this embodiment, the plate body 621 of the inclined movable plate 62, the fixed plate 61 and the side wall of the feces trough 30 are jointly arranged to form a roughly V-shaped feces collecting space 65. The connection between the movable plate 62 and the fixed plate 61 is located at the bottom of the feces collecting space 65. The inclined arrangement of the movable plate 62 and the fixed plate 61 can better guide the feces and urine in the feces collecting space 65 to the connection between the movable plate 62 and the fixed plate 61, thereby making the discharge of feces and urine in the feces collecting space 65 smoother.

[0038] In this embodiment, multiple elastic support members 63 can be provided, and the multiple elastic support members 63 are arranged at intervals along the length direction of the movable plate 62. The opposite ends of each elastic support member 63 are rotatably connected to the movable plate 62 and the side wall of the manure trough 30. Figure 3 In this embodiment, the elastic support member 63 is arranged below the movable plate 62. The elastic support member 63 includes a telescopic rod 631 and a spring 636. One end of the telescopic rod 631 is rotatably connected to the movable plate 62. Specifically, one end of the telescopic rod 631 is provided with a rotation hole (not shown), and the telescopic rod 631 is rotatably sleeved on the mounting shaft 625 through the rotation hole. When there are multiple elastic support members 63, the mounting seat 624 and the mounting shaft 625 of the movable plate 62 are correspondingly provided with multiple, and the telescopic rods 631 of the multiple elastic support members 63 are rotatably connected to the multiple mounting shafts 625 respectively. The other end of the telescopic rod 631 is rotatably connected to the side wall of the manure trough 30. Specifically, a fixing seat 36 is fixed on the side wall of the manure trough 30, and a fixing shaft 37 is penetrated on the fixing seat 36. The other end of the telescopic rod 631 is provided with a rotation hole (not shown), and the telescopic rod 631 is rotatably sleeved on the fixing shaft 37 through the rotation hole. When there are multiple elastic support members 63 , multiple fixing seats 36 are correspondingly provided, and the telescopic rods 631 of the multiple elastic support members 63 are rotatably connected to the fixing shafts 37 of the multiple fixing seats 36 .

[0039] The spring 636 is a compression spring, which is sleeved on the telescopic rod 631 and elastically abuts against the mounting shaft 625 of the movable plate 62 and the fixed shaft 37 on the side wall of the manure tank 30. In this embodiment, the telescopic rod 631 includes a shaft 634 and a sliding sleeve 635 slidably sleeved on the shaft 634, and the free end of the shaft 634 is provided with the rotating hole, and the shaft 634 is rotatably connected to the mounting shaft 625 of the movable plate 62 through the rotating hole. The free end of the sliding sleeve 635 is provided with the rotating hole, and the sliding sleeve 635 is rotatably connected to the fixed shaft 37 on the side wall of the manure tank 30 through the rotating hole.

[0040] The feces collecting space 65 is used to collect feces and urine dropped from the slatted floor 23. When the feces and urine in the feces collecting space 65 reaches a preset weight, the elastic support member 63 is forced to contract so that the movable plate 62 rotates in a direction away from the fixed plate 61, and then separates from the lower end of the fixed plate 61 and the lower end of the movable plate 62 to form a feces outlet (not shown), which connects the feces collecting space 65 and the feces soaking trough 30.

[0041] In this embodiment, the fixed plate 61, the movable plate 62 and the elastic support member 63 are all made of anti-corrosion materials to extend the service life of the equipment.

[0042] Please see again Figure 1In this embodiment, the livestock and poultry manure odor treatment device further includes an odor purification box 70, which is connected to the top of the manure tank 30 through an air duct 71. Specifically, a trachea joint 38 is fixed to the top of the manure tank 30, and the trachea joint 38 is passed through the wall of the breeding plant 10, so that one end of the trachea joint 38 is connected to the manure tank 30, and the other end extends to the outside of the breeding plant 10; the end of the air duct 71 away from the odor purification box 70 can be detachably connected to the trachea joint 38 by plugging or the like. The trachea joint 38 of this embodiment can adopt a pipe joint of the prior art, and the structure of the odor purification box 70 belongs to the prior art. For example, reference can be made to an odor purification box in an indoor breeding farm with adjustable temperature and humidity disclosed in announcement number CN219205510U.

[0043] When the livestock and poultry manure odor treatment device is used, the sewage valve 34 is first closed, and the water valve of the water inlet 32 ​​of the manure soaking tank 30 is opened to let water in, so that the water in the manure soaking tank 30 reaches a preset liquid level and then the water valve is closed. At this time, the water inlet 32 ​​and the air pipe joint 38 are both located above the liquid level of the manure soaking tank 30. Then, the air guide pipe 71 is put on the air pipe joint 38, and the odor purification box 70 is started to feed pigs.

[0044] In the initial state, the lower end of the movable plate 62 is in contact with the lower end of the fixed plate 61. At this time, the groove 626 at the lower end of the movable plate 62 is engaged with the convex teeth 611 at the lower end of the fixed plate 61, and the feces and urine generated during the animal breeding process fall through the slatted floor 23 to be collected in the feces collecting space 65. When the amount of feces and urine on the feces collecting bucket 60 reaches a preset weight, that is, when the weight of the feces and urine in the feces collecting bucket 60 and the movable plate 62 exceeds the supporting force of the spring 636 of the elastic support member 63, the spring 636 of the elastic support member 63 is further compressed, and the telescopic rod 631 shrinks together with the spring 636, so that the movable plate 62 rotates in a direction away from the fixed plate 61, and then separates from the lower end of the fixed plate 61 and the lower end of the movable plate 62 to form a feces drop opening. At this time, the feces and urine on the feces collecting bucket 60 fall into the feces soaking tank 30 through the feces drop opening. Since the movable plate 62 and the fixed plate 61 are arranged at an angle, when the feces outlet is opened, the feces and urine on the movable plate 62 and the fixed plate 61 can quickly fall from the feces outlet, so that the feces and urine in the feces collecting bucket 60 can be emptied.

[0045] When the manure collecting bucket 60 is emptied, under the elastic restoring force of the spring 636, the movable plate 62 rotates toward the fixed plate 61 until the groove 626 at the lower end of the movable plate 62 is engaged with the convex teeth 611 at the lower end of the fixed plate 61, so that the manure collecting bucket 60 is in a V-shaped state for the next manure collection. This cycle is repeated until the pigs are released from the market or transferred to another pen. At the same time, during the breeding period, the odor in the manure trough 30 can be extracted and purified by the odor purification box 70 and then discharged to the outside.

[0046] After the pigs are released from the market or transferred to the new pens, the odor purification box 70 is closed, the sewage valve 34 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. The manure trough 30 and the manure collection bucket 60 are cleaned and disinfected to prepare for the next batch of pigs.

[0047] The above-mentioned livestock and poultry manure odor treatment device is provided with a manure collection bucket 60 for collecting manure at the top opening 31 of the manure trough 30. In the initial state, the movable plate 62 of the manure collection bucket 60 is in a contacting closed state with the fixed plate 61 to reduce the circulation of air between the manure trough 30 and the barn; when the manure collected in the manure collection bucket 60 reaches a preset weight, the elastic support member 63 is compressed and contracted to open the manure collection bucket 60 and then let the manure in the manure collection bucket 60 fall into the manure trough 30. Compared with the traditional open manure trough 30, it can reduce the diffusion of odor generated by the manure trough 30 into the pig barn, allowing pigs to live more comfortably and benefiting their health. In addition, the above-mentioned livestock and poultry manure odor treatment device has a manure collection bucket 60 with a simple structure, which is easy to clean, not prone to clogging, and easy to use.

[0048] The above-mentioned livestock and poultry manure odor treatment device purifies the odor continuously generated by the manure stored in the manure trough 30 for a long time through the odor purification box 70 and then discharges it, thereby reducing the pollution of the farm odor to the surrounding environment.

[0049] 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.
