Abstract
Description
Technical Field
[0001] This utility model relates to the field of chicken manure pulping technology, specifically to a chicken manure desanding and feather removal pulping device. Background Technology
[0002] Currently, my country has a massive livestock and poultry farming industry. If these resources are not properly and promptly managed, they will harm the atmosphere, water bodies, soil, and human health. Anaerobic digestion is one of the main resource utilization technologies for livestock and poultry manure both domestically and internationally. However, chicken feed requires the addition of a large amount of sand, and chickens shed a significant amount of feathers during molting, resulting in chicken manure containing a large amount of grit and feathers. If this manure is directly fed into an anaerobic digester, it will cause rapid accumulation in the digester, requiring frequent cleaning and causing wear and tear on pipes and equipment. Utility Model Content
[0003] The main purpose of this invention is to provide a chicken manure desanding and feather removal and pulping device, which aims to solve the above-mentioned problems.
[0004] To achieve the above objectives, this utility model proposes a chicken manure desanding, defecation, and pulping device, comprising: The tank body has a mixing zone, a settling zone, and a sand discharge zone arranged sequentially along its vertical direction. The mixing zone has an inlet and an outlet on its sidewalls, located on opposite sides of the tank body's axis. The inlet is used to feed chicken manure slurry into the tank, and the outlet is used to discharge treated chicken manure slurry out of the tank. The settling zone has a decreasing cross-sectional area from top to bottom. The sand discharge zone is funnel-shaped, and its sidewall has a sand discharge port to allow sand and gravel within the sand discharge zone to be discharged out of the tank. A chicken manure treatment component includes a mixer and multiple guide plates. The mixer is located on the center line of the mixing zone and is used to disperse the chicken manure slurry in the mixing zone. The multiple guide plates are located in the mixing zone and on the outer periphery of the mixer, and are distributed at intervals along the circumference of the mixing zone.
[0005] Optionally, the stirrer includes a rotating shaft, blades, and a driving component. The rotating shaft extends in a vertical direction, with one end connected to the blades. The driving component is driven to the other end of the rotating shaft to drive the rotating shaft to rotate the blades around the axis of the rotating shaft.
[0006] Optionally, the length of the blade is greater than the diameter of the bottom end of the settling zone.
[0007] Optionally, the tank is equipped with a radar level gauge for measuring the liquid level inside the tank.
[0008] Optionally, the diameter of the stirring zone is twice the diameter of the bottom end of the settling zone.
[0009] Optionally, the ratio of the volume of the stirring zone to the volume of the settling zone is 3:1.
[0010] Optionally, the depth of the stirring zone is the same as its diameter.
[0011] Optionally, the feed inlet is located near the bottom of the mixing zone, and the discharge outlet is located near the middle of the mixing zone.
[0012] Optionally, the cross-sectional area of the discharge port is larger than the cross-sectional area of the inlet port.
[0013] Optionally, the chicken manure desanding and defecation pulping device further includes a support frame, on which the tank is mounted.
[0014] In this invention, chicken manure slurry enters the mixing zone of the tank through the feed inlet and rotates under the action of the agitator. During rotation, the slurry collides with the guide plate, thus breaking up large particles and dispersing the sand and feathers carried within the chicken manure particles into the slurry. The heavier sand and gravel fall under gravity and through the settling zone to the sand discharge zone, where they can be discharged from the tank through the sand discharge port. The lighter chicken feathers float on the surface of the slurry due to buoyancy. Regular cleaning is possible, achieving efficient removal of sand and feathers from chicken manure slurry. Simultaneously, the manure pellets in the slurry are further crushed by the agitator, achieving efficient pulping. The chicken manure particles in the slurry are also evenly dispersed by the agitator, achieving uniform slurry preparation. After the removal of sand and feathers, the chicken manure slurry is discharged at a uniform speed through the outlet and enters the anaerobic digester for anaerobic digestion. This significantly reduces the sludge accumulation time in the anaerobic digester, decreases the frequency of tank cleaning, reduces the wear rate of the anaerobic digester, and extends its service life.

[0022] Currently, my country has a massive livestock and poultry farming industry. If these resources are not properly and promptly managed, they will harm the atmosphere, water bodies, soil, and human health. Anaerobic digestion is one of the main resource utilization technologies for livestock and poultry manure both domestically and internationally. However, chicken feed requires the addition of a large amount of sand, and chickens shed a significant amount of feathers during molting, resulting in chicken manure containing a large amount of grit and feathers. If this manure is directly fed into an anaerobic digester, it will cause rapid accumulation in the digester, requiring frequent cleaning and causing wear and tear on pipes and equipment.
[0023] In view of this, the present invention provides a chicken manure desanding, defecation, and pulping device 100. Figure 1 and Figure 2An embodiment of the chicken manure sand and feather removal and pulping device 100 provided by this utility model. Please see Figure 1 and Figure 2 The chicken manure desanding and defecation slurry making device 100 includes a tank body 1 and a chicken manure treatment component 2. The tank body 1 has a stirring zone 11, a settling zone 12, and a sand removal zone 13 arranged sequentially along its vertical direction. The stirring zone 11 has an inlet A and an outlet B on its peripheral wall, located on opposite sides of the tank body 1's axis. The inlet A is used to transport chicken manure slurry into the tank body 1, and the outlet B is used to transport the treated chicken manure slurry out of the tank body 1. The settling zone 12 has a horizontal... The cross-sectional area decreases from top to bottom. The sand discharge zone 13 is funnel-shaped and has a sand discharge port C on its side wall to discharge the sand and gravel in the sand discharge zone 13 out of the tank 1. The chicken manure treatment component 2 includes a stirrer 21 and multiple guide plates 22. The stirrer 21 is located on the center line of the stirring zone 11 and is used to disperse the chicken manure slurry in the stirring zone 11. The multiple guide plates 22 are located in the stirring zone 11 and are located on the outer periphery of the stirrer 21 and are distributed at intervals along the circumference of the stirring zone 11.
[0024] In this utility model, chicken manure slurry enters the stirring zone 11 of the tank 1 through the feed inlet A and rotates under the action of the agitator 21. During the rotation, the chicken manure slurry collides with the guide plate 22, thus breaking up large particles in the slurry. Gravel and chicken feathers carried in the chicken manure particles are dispersed into the slurry. The heavier gravel falls under the action of gravity and falls into the sand discharge zone 13 through the settling zone 12, and can then be discharged out of the tank 1 through the sand discharge port C. The lighter chicken feathers float under the buoyancy of the slurry. On the liquid surface, it can be cleaned periodically to achieve efficient removal of sand and feathers from the chicken manure slurry. At the same time, the manure pellets in the chicken manure slurry are crushed a second time under the action of the agitator 21 to achieve efficient pulping. The chicken manure particles in the slurry are evenly dispersed under the action of the agitator 21 to achieve uniform slurry preparation. After the sand and feathers are removed, the chicken manure slurry is discharged at a uniform speed through the discharge port B and enters the anaerobic digester for anaerobic digestion. This can greatly reduce the sludge accumulation time in the anaerobic digester, reduce the frequency of tank cleaning, reduce the wear rate of the anaerobic digester, and extend the service life of the anaerobic digester.
[0025] Compared to the traditional method of using a steel-concrete pool for chicken manure pulping, the diameter of the tank 1 in the chicken manure desanding and defecation pulping device 100 provided by this utility model is smaller under the same processing scale. During the pulping process, the residence time of the chicken manure slurry is less than 30 minutes, which is much less than the 24-hour residence time of the chicken manure slurry in the steel-concrete pool, greatly improving the pulping and homogenization efficiency.
[0026] The chicken manure desanding, defecation, and pulping device 100 provided by this utility model has a small footprint, large processing capacity, can quickly remove sand and feathers, is easy to maintain, has a hygienic working environment, and reduces odor release.
[0027] It should be noted that the chicken manure desanding and feather removal slurry making device 100 provided by this utility model can quickly remove sand and chicken feathers with a particle size greater than 0.5mm, and perform secondary crushing of manure balls smaller than 30mm in the chicken manure slurry.
[0028] It should also be noted that, in this invention, the shape of the stirring zone is not limited, as long as the upper end face of the settling zone matches the lower end face of the stirring zone, and the upper end face of the sand discharge zone matches the lower end face of the settling zone. Specifically, the stirring zone can be cylindrical or cubic, etc., and correspondingly, the settling zone can be frustum-shaped or truncated cone-shaped, and the sand discharge zone can be frustum-shaped or truncated cone-shaped.
[0029] For further details, please refer to Figure 1 The stirrer 21 includes a rotating shaft 211, a blade 212 and a driving member 213. The rotating shaft 211 extends in the vertical direction, and one end of it is connected to the blade 212. The driving member 213 is driven to the other end of the rotating shaft 211 so as to drive the rotating shaft 211 to drive the blade 212 to rotate around the axis of the rotating shaft 211.
[0030] More specifically, the driving component 213 is a drive motor.
[0031] Specifically, in one embodiment of this invention, the length of the impeller 212 is greater than the diameter of the bottom end of the settling zone 12. Under the same stirring effect, a larger impeller can reduce the stirring speed and reduce the secondary interference of the eddies formed by stirring on the bottom sediments of the tank 1.
[0032] For details, please refer to Figure 1 and Figure 2 The tank 1 is equipped with a radar level gauge 3 for measuring the liquid level inside the tank 1.
[0033] Specifically, in one embodiment of this invention, the diameter of the stirring zone 11 is twice the diameter of the bottom end of the settling zone 12. This improves the compatibility of continuous sand discharge devices with different types of interfaces and enables wider application to other general-purpose equipment.
[0034] Specifically, the volume ratio of the mixing zone 11 to the settling zone 12 is 3:1. This satisfies the mixing time requirements of the mixing zone 11 for the chicken manure slurry while ensuring that the sand and other debris deposited in the sand discharge zone 13 are not disturbed by the agitator 21 within the mixing zone 11. The residence time of the chicken manure slurry in the mixing zone 11 is greater than the residence time of the sand and gravel in the settling zone 12.
[0035] Specifically, in one embodiment of this invention, the depth of the stirring zone 11 is the same as its diameter. In this case, the material usage of the tank body 1 is minimized, resulting in the best economic benefits.
[0036] For details, please refer to Figure 1 The feed inlet A is located near the bottom of the mixing zone 11, and the discharge outlet is located near the middle of the mixing zone 11. This increases the effective residence time of the chicken manure slurry, giving sufficient time for pulping and separation of chicken manure and gravel, ensuring complete separation of gravel from the chicken manure.
[0037] Specifically, the cross-sectional area of the discharge port B is larger than that of the feed port A. The smaller cross-sectional area of the feed port A increases the feed flow rate, reduces the amount of particulate chicken manure and gravel deposited around the feed port A, and reduces the frequency of maintenance; the larger cross-sectional area of the discharge port B reduces the discharge flow rate, avoids the carryover of scum and fine gravel in the outflow, and ensures the quality of pulping.
[0038] Specifically, the settling zone 12 has an angle of 55° with the horizontal plane, which facilitates the falling of sand and gravel in the chicken manure slurry along the side wall of the settling zone 12.
[0039] For details, please refer to Figure 1 The chicken manure desanding and defecation pulping device 100 also includes a support frame 4, on which the tank body 1 is mounted. More specifically, the support frame 4 includes two support pipes, which are symmetrically arranged along the axis of the tank body 1 and respectively connected to the tank body 1 to support the tank body 1.
[0040] Specifically, the part of the tank 1 corresponding to the settling zone 12 is connected to the part of the tank 1 corresponding to the stirring zone 11 via a flange, which ensures a stable connection and simple operation.
[0041] Specifically, a sand discharge pipe is provided at the sand discharge port C to discharge the sand and gravel in the sand discharge area 13 into the tank 1.
[0042] Specifically, the guide plate 22 is fixedly installed on the inner wall of the tank 1.
[0043] It should be noted that in this utility model, the number of guide vanes 22 is limited; it can be three, four, five, etc. For details, please refer to [link / reference needed]. Figure 2 In one embodiment of the present invention, four guide plates 22 are provided, and the four guide plates 22 are evenly spaced along the circumference of the stirring zone 11.
[0044] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
