Technical Field

[0001] The invention belongs to the technical field of feces dehydration treatment, and in particular relates to a dehydration treatment device for animal husbandry feces. Background Art

[0002] Animal husbandry is part of agriculture and animal husbandry. Animal husbandry is a production sector that utilizes the physiological functions of domesticated animals such as livestock and poultry, or wild animals such as deer, musk deer, foxes, minks, otters, and quails, through artificial breeding and reproduction, to transform plant energy such as grass and feed into animal energy to obtain livestock products such as meat, eggs, milk, wool, cashmere, hides, silk, and medicinal materials.

[0003] The existing livestock manure dehydration treatment device places the animal manure in a dehydration barrel to filter the water when dehydrating the animal manure. When the manure is dry and the weight is reduced, the manure in the dehydration barrel is dried by high-temperature air drying and taken out of the dehydration barrel.

[0004] During this process, if the conveyor transports feces too fast or the feces are too humid, the feces will accumulate in the dehydration barrel; when the feces accumulate, the pressurized air is blocked by the accumulated feces and the wind force is dispersed, and it cannot provide effective upward thrust, which aggravates the accumulation of feces; and when the feces accumulate, the pressurized air blows hot air from bottom to top, which can easily cause the feces accumulated on the upper layer to fail to be heated in time, and the heated feces at the bottom cannot be discharged upward in time.

[0023] A method for using a dehydration treatment device for livestock breeding manure, which is applied to any of the above-mentioned dehydration treatment devices for livestock breeding manure, comprises the following steps:

[0024] S1: The feces are transported to the dehydration barrel by the feeder, and then fall onto the electric heating sieve plate for heating. At the same time, part of the water in the feces is filtered to the lower side of the electric heating sieve plate, the pressurized fan is started, the No. 2 air duct is turned on, and the pressurized wind flows upward from the bottom of the electric heating sieve plate, thereby performing wind heat treatment on the feces.

Through the combined action of the pressurized fan and the air pump, the feces are moved to the outside of the dehydration barrel with the hot air;

[0025] S2: When feces accumulate in the dehydration barrel, the control system drives the outer jacket to rotate by controlling the driving component, and the outer jacket drives the stirring mechanism to stir and heat the feces, thereby effectively breaking and heating the feces accumulated on the upper layer. At the same time, the control system controls the No. 1 air duct to be turned on and the No. 2 air duct to be closed; the No. 1 air duct blows hot air to the feces accumulated on the upper layer from the upper part of the electric heating screen plate, and the No. 1 air duct and the air pump cooperate to dry and transport the feces accumulated on the upper layer;

[0026] S3: When feces accumulate, the telescopic rod contracts, and the outer cover can be connected with the sleeve, and part of the feces enters the sleeve. The control system controls the conveying mechanism to heat the accumulated feces and convey it upward.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. When feces accumulate, the PLC controller drives the outer jacket to rotate by controlling the driving component, and the outer jacket drives the stirring mechanism to stir and heat the feces, thereby effectively breaking and heating the feces accumulated on the upper layer. At the same time, the control system controls the No. 1 air duct to be turned on and the No. 2 air duct to be closed by controlling two solenoid valves; the No. 1 air duct blows hot air to the feces accumulated on the upper layer from the upper part of the electric heating screen plate. Through the cooperation of the No. 1 air duct and the air pump, the feces accumulated on the upper layer can be effectively dried and transported;

[0029] 2. In the stirring mechanism, the stirring of the vertical electric heating rod and the horizontal electric heating rod can make the feces piled at different heights evenly heated. At the same time, under the stirring action of the vertical electric heating rod and the horizontal electric heating rod, the feces are evenly distributed on the electric heating screen plate; during stirring, the gap in the stirring part increases, thereby increasing the wind force in the stirring part, which can further improve the transportation efficiency of feces in the stirring part;

[0030] 3. When the feces accumulate, the telescopic rod contracts, and the upper toothed disc meshes with the lower toothed disc. Under the rotation of the outer jacket, the outer jacket and the electric heating screen plate vibrate vertically, so that the accumulated feces continue to vibrate, increasing the contact area between the feces and the wind, and improving the drying and conveying effect of the feces;

[0031] 4. When feces accumulates, the telescopic rod contracts. At this time, the outer jacket can be connected with the sleeve, and some feces enter the sleeve. The PLC controller controls motor No. 1 to start, and motor No. 1 drives the shaft to rotate. The shaft drives the electric heating network to heat the feces and transport the feces upward, so that the feces is close to the air pump, further improving the dehydration and transportation efficiency of the feces.

[0032] 5. The annular air tube is inclined and has a plurality of air holes, which can generate upward buoyancy for the feces through the air holes. At the same time, the air holes of the annular air tube can blow the feces into the sleeve, thereby increasing the conveying efficiency of the conveying mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] Working principle:

[0065] A method for using a dehydration treatment device for livestock and animal husbandry manure, which is applied to the dehydration treatment device for livestock and animal husbandry manure in the above embodiment, comprises the following steps:

[0066] S1: The feeder conveys the feces to the dehydration barrel 1, and then the feces falls onto the electric heating sieve plate 10 for heating. At the same time, part of the water in the feces is filtered to the lower side of the electric heating sieve plate 10, and the pressure sensor on the telescopic rod 11 monitors and records the pressure value;

[0067] S2: When the pressure value of the pressure sensor is less than the threshold value, the PLC controller controls the No. 2 air duct 16 to be turned on and the No. 1 air duct 15 to be turned off, and the pressurized wind flows upward from the bottom of the electric heating sieve plate 10, and the electric heating sieve plate 10 starts to heat the feces, thereby performing wind heat treatment on the feces. At the same time, the air pump 20 starts intermittently to generate upward suction, and through the joint action of the pressurized fan 14 and the air pump 20, the feces are moved to the outside of the dehydration barrel 1 with the hot air;

[0068] S3: When feces accumulate, when the pressure value of the pressure sensor exceeds the threshold value, the PLC controller drives the outer cover 6 to rotate by controlling the driving component 7, and the outer cover 6 drives the stirring mechanism 8 to stir and heat the feces, thereby effectively breaking and heating the feces accumulated on the upper layer.

At the same time, under the stirring action of the vertical electric heating rod 82 and the horizontal electric heating rod 83, the feces are evenly distributed on the electric heating screen plate 10; when the vertical electric heating rod 82 and the horizontal electric heating rod 83 stir, the gap in the stirring part increases, so that the wind force in the stirring part increases, which can further improve the conveying efficiency of the feces in the stirring part;

[0070] When feces accumulate on the electric sieve plate 10, the telescopic rod 11 at the bottom of the electric sieve plate 10 contracts, and at this time, the outer jacket 6 drives the upper toothed disc 17 to move downward, and the upper toothed disc 17 is meshed with the lower toothed disc 18; since the lower toothed disc 18 is fixedly connected to the base 3, the lower toothed disc 18 is fixed, and the outer jacket 6 can continuously rotate under the power of the driving component 7, so under the rotation of the outer jacket 6, the upper toothed disc 17 continuously rotates relative to the lower toothed disc 18; and the outer jacket 6 is rotatably connected to the electric sieve plate 10, so under the elastic force of the telescopic rod 11, the outer jacket 6 and the electric sieve plate 10 reciprocate vertically, so that the accumulated feces are constantly vibrating, increasing the contact area between the feces and the wind force, and improving the drying and conveying effect of the feces;

[0071] And when feces accumulates, the telescopic rod 11 contracts, and the outer sleeve 6 can be connected with the sleeve 4 at this time, and part of the feces enters the sleeve 4. The PLC controller controls the No. 1 motor 51 to start, and the No. 1 motor 51 drives the rotating shaft 52 to rotate. The rotating shaft 52 drives the electric heating network 53 to heat the feces and transport the feces upward, so that the feces is close to the air pump 20, further improving the dehydration and transportation efficiency of the feces.

Meanwhile, the air holes of the annular air tube 19 can blow the feces into the sleeve 4 , thereby increasing the conveying efficiency of the conveying mechanism 5 .
