Description

Technical Field

[0001] The present invention relates to the technical field of livestock and poultry manure compaction, and specifically to a continuous step-by-step compaction treatment device based on the reuse of livestock and poultry manure. Background Technique

[0002] Livestock and poultry manure compaction treatment is a technology for reducing the volume and recycling of breeding waste through physical and mechanical methods, aiming to reduce environmental pollution and achieve resource reuse. In the early stage, a screen, centrifuge or screw extruder is used to initially separate the solid and liquid in the manure, remove large particle impurities, and then add a flocculant or adjust the pH value to promote the aggregation of solid particles and improve the subsequent dehydration efficiency.

[0003] The core goal of livestock and poultry manure treatment is to achieve volume reduction and resource recycling through solid-liquid separation. Currently, the mainstream technologies include centrifugal separation, extrusion dehydration, composting fermentation, and anaerobic treatment. For example, the utility model patent with the publication number CN221752559U uses a push plate and spring structure to achieve solid-liquid separation, and uses the vibration of the filter screen to improve the solid-liquid separation effect. However, the single extrusion pressure is fixed, which easily leads to a relatively high moisture content of the manure residue, and there is a lack of a multi-stage treatment mechanism, resulting in a relatively high subsequent drying cost. In addition, most current technologies focus on a single treatment link and lack an integrated and continuous solution. Summary of the Invention

[0004] The purpose of the present invention is to provide a continuous step-by-step compaction treatment device based on the reuse of livestock and poultry manure to solve the problems mentioned in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A continuous step-by-step compaction treatment device based on the reuse of livestock and poultry manure, including a sorting cover and a compaction box. The top of the sorting cover is fixedly connected to the compaction box. A polymerization cylinder is fixedly installed inside the compaction box. A sleeve is sleeved and installed on the outer wall of the polymerization cylinder. A feeding control box is fixedly connected to the side of the sleeve with teeth installed on the outer wall inside the compaction box.

[0006] A pressing plate one and a movable extrusion mechanism are slidably connected inside the polymerization cylinder. The movable extrusion mechanism includes a pressing plate two and a T-shaped cylinder. The pressing plate two is slidably connected to the inner wall of the polymerization cylinder on the side of the pressing plate one. A T-shaped cylinder is fixedly connected to the side wall of the pressing plate two. The two sides of the T-shaped cylinder are symmetrically rotatably connected to the rotating arms through bearings.

[0007] A crankshaft is movably connected inside the compaction box on the side of the pressing plate one. A swing arm is sleeved and movably connected to the crankshaft. One side of the swing arm is rotatably connected to the side wall of the pressing plate one through a connecting rod. The two rotating arms are respectively movably connected to the two sides of the crankshaft in correspondence.

[0008] Further, through openings are correspondingly formed on both sides of the polymerization cylinder, and the included angle of the radii of the top through openings is twice that of the bottom through openings. A discharge port is formed at the top of the pressure polymerization box, and the discharge port corresponds to the through opening on the side wall of the polymerization cylinder. A filter plate is installed on the outer wall of the sleeve and located at the through opening on the bottom side wall of the polymerization cylinder.

[0009] Further, a motor is installed in the feeding control box. The output end of the motor is sleeved with a gear which is meshed with the tooth pattern on the outer wall of the sleeve. A motor is installed on the outer wall of the pressure polymerization box, and the output end of the motor penetrates through the side of the pressure polymerization box and is fixed to the end of the crankshaft.

[0010] Further, a pressure polymerization adjustment box is installed on the side of the pressure polymerization box. A cam is movably connected to the side of the pressure polymerization adjustment box, and an arc-shaped adjustment rod is movably connected to the side of the cam. An eccentric sleeve wheel is movably connected to the bracket on one side of the pressing plate in the pressure polymerization box. One side of the arc-shaped adjustment rod is rotatably connected to the eccentric sleeve wheel. An abutting sleeve rod is movably connected to the outer wall of the eccentric sleeve wheel, and one end of the abutting sleeve rod is rotatably connected to the swing arm.

[0011] Further, a positioning box is fixedly connected to the bracket on the other side of the pressing plate in the pressure polymerization box. An arc-shaped groove is formed in the inner wall of the positioning box, and a spring is installed in the positioning box.

[0012] Further, the pressure polymerization box side active extrusion mechanism further includes a release plate and a sliding column. The release plate is slidably connected in the second pressing plate. The sliding column is slidably connected in the positioning box. One end of the sliding column respectively penetrates through the T-shaped column cylinder and the second pressing plate and is fixed to the release plate. The protrusion on the side wall of the sliding column abuts against the arc-shaped groove on the inner wall of the positioning box.

[0013] Further, liquid collecting grooves and slag discharging grooves are respectively formed on both inner walls of the upper part of the sorting cover at the bottom of the pressure polymerization box. Partition plates are movably connected to both inner walls of the sorting cover and located at the bottom through openings of the polymerization cylinder. The output end of the motor installed on the outer wall of the sorting cover is fixed to the central axis of the partition plate.

[0014] The continuous step-by-step pressure polymerization treatment method for the recycling of livestock and poultry manure is as follows:

[0015] Anti-detachment step-by-step feeding is combined with internal pushing for primary extrusion:

[0016] The feeding control box automatically controls the motor to rotate the sleeve according to the weight of the livestock and poultry manure accumulated at the discharge port at the top of the pressure polymerization box. The livestock and poultry manure enters through the top through opening of the polymerization cylinder. The motor is synchronously started to drive the crankshaft to rotate. The swing arm on the crankshaft presses the end of the connecting rod against the first pressing plate. At the same time, the reverse movement on both sides of the crankshaft pulls the T-shaped column cylinder installed at the end of the rotating arm, causing the T-shaped column cylinder to push the second pressing plate as a whole to move towards the first pressing plate in the polymerization cylinder, squeezing and dehydrating the discharged livestock and poultry manure. The separated liquid with high moisture content falls into the sorting cover through the filter plate on the outer wall of the sleeve and flows into the liquid collecting groove through the guiding of the partition plate;

[0017] The anti-sticking rotary material discharging stirrer performs secondary extrusion:

[0018] The cam on the side wall of the pressure aggregation adjusting box rotates, driving the arc-shaped adjusting rod to turn over while pulling the entire eccentric sleeve wheel to rotate. When the crankshaft rotates, the advancing distance of the pressing plate where the connecting rod at the swing arm end abuts increases, while the pressing plate two maintains a fixed moving distance. The minimum squeezing distance between the pressing plate one and the pressing plate two decreases, and the applied pressure increases, realizing further dehydration treatment of the manure residue. At the same time, with the reset of the pressing plate two, the front end stripping plate drives the pressed manure residue to move. When the sliding column rotates in the arc-shaped groove, the manure residue at the end of the pressing plate two rotates and rubs against the inner wall of the polymerization cylinder to break, and is discharged into the slag discharge groove through the partition plate guidance.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In the present invention, through the continuous step-by-step pressure aggregation design, the increasing pressure is applied in stages to gradually destroy the combined structure of solid and water in the livestock and poultry manure. In the primary extrusion stage, the crankshaft drives the swing arm to cooperate with the pressing plate one and the pressing plate two to apply pressure, realizing preliminary dehydration. In the secondary extrusion stage, the pressure aggregation adjusting box dynamically adjusts the advancing distance of the pressing plate one through the cam and the eccentric sleeve wheel, further reducing the extrusion distance, applying a higher pressure. Compared with the traditional single-stage pressing, the step-by-step pressurization can reduce the moisture content of the manure residue. In addition, the stripping plate and the sliding column structure break the manure residue by friction when the pressing plate two resets, avoiding cake-like blockage, and combining the partition plate guidance to separate liquid and solid, improving the dehydration efficiency and continuity;

[0021] 2. In the present invention, the equipment adopts a linkage mechanism of the pressure aggregation adjusting box and the eccentric sleeve wheel, and the initial position of the swing arm is adjusted in real time through the rotation of the cam, realizing the step-by-step increase of pressure without stopping for adjustment. At the same time, the differential design of the top and bottom openings of the polymerization cylinder and the cooperation with the sleeve filter plate ensure the efficient separation of liquid during the extrusion process. For different manure characteristics, the treatment effect can be optimized by adjusting parameters such as the sleeve rotation speed, the angle of the eccentric sleeve wheel, and the pressing plate distance. The partition plate in the sorting cover is designed separately from the liquid collecting tank and the slag discharge tank, further realizing the automatic classification and collection of liquid and solid, and improving the versatility and large-scale treatment capacity of the equipment.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1-6 , the present invention provides a technical solution:

[0031] Embodiment 1: The step-by-step pressure aggregation treatment equipment, that is, staged and multi-stage pressing and dehydration, has significant advantages in the treatment of livestock and poultry manure, especially in improving dehydration efficiency, reducing energy consumption, and enhancing the quality of the product. As Figure 1 and Figure 2 shown, the combination of the polymerization cylinder 4 and the sleeve 5 is adopted, and the driving component is used to control the movement of the two pressing plates inside the polymerization cylinder 4 to carry out extrusion dehydration of livestock and poultry manure and automatically crush the formed manure residue. At the same time, the driving component pressurizes in stages, and through the gradual increase of multi-stage pressure, the combined structure of solid and water in the manure is gradually destroyed step by step, so that the water is released more thoroughly;

[0032] Figure 1 As shown in , a discharge port 3 is opened at the top of the pressure aggregation box 2, and a weighing sensor is arranged at the bottom of the discharge port 3 to obtain the weight of the livestock and poultry manure fed each time, and control the rotation of the motor in the discharge control box 6 after reaching the discharge threshold, so as to realize the rotation of the sleeve 5 at the top of the polymerization cylinder 4;

[0033] As Figure 4As shown in the figure, through openings are provided on the outer walls of the polymerization cylinder 4 and the sleeve 5. By alternately overlapping the through openings of the two, automatic feeding and discharging are realized. It should be noted that as the sleeve 5 rotates on the polymerization cylinder 4, when the top of the polymerization cylinder 4 is opened, if the bottom through opening of the polymerization cylinder 4 is the same size as its top through opening and the covering area of the sleeve 5 is the same, then the through openings on both sides will be opened simultaneously, which cannot meet the storage of livestock and poultry manure in the polymerization cylinder 4;

[0034] Therefore, the radius angle of the top through opening of the polymerization cylinder 4 is twice that of the bottom through opening, that is, the angles between the two sides of the through opening and the center line of the polymerization cylinder 4 are different, and the sizes of the through openings are different. Therefore, after the top through opening is opened, the bottom through opening is still in the state of being wrapped by the sleeve 5, which is convenient for the liquid to be discharged during extrusion. A ceramic filter plate is installed on the bottom sleeve 5. At the same time, it is convenient to control the rotation angle of the sleeve 5. The gear at the end of the motor in the feeding control box 6 is meshed with the tooth pattern on the sleeve 5 to automatically control the rotation of the sleeve 5;

[0035] The livestock and poultry manure entering the polymerization cylinder 4 starts to perform step-by-step extrusion and dehydration operations. The driving mechanism is as Figure 3 shown. By using the rotation of the crankshaft 12 to adjust the position of the connecting rod on the swing arm 13, the pressing plate 7 connected to the end of the connecting rod is thus extruded. The pressing plate 7 is located inside the polymerization cylinder 4, and an active extrusion mechanism 8 is installed on the other side of it. A pressing plate 801 is provided inside this mechanism, which is combined with the pressing plate 7 to perform combined pressing, thereby realizing the dehydration of livestock and poultry manure. Since the single discharge amount is certain, if the travel distances of the pressing plate 7 and the pressing plate 801 are certain, the extrusion force generated inside the polymerization cylinder 4 is fixed, resulting in a relatively stable moisture content of the livestock and poultry manure;

[0036] To make the moisture release of the livestock and poultry manure more thorough, an upper swing arm 13 and an abutting sleeve rod 14 for adjusting the swing arm 13 are provided. As Figure 3 shown, when the crankshaft 12 rotates, the middle crankshaft 12 and the two side crankshafts 12 are respectively on both sides of the bracket, that is, the middle moves inward and the two sides move outward. When the swing arm 13 installed on the middle crankshaft 12 moves inward, it maintains its attitude and moves inward. The end of the connecting rod pushes the pressing plate 7 to move. The two side crankshafts 12 move outward, and the end of the rotating arm 804 sleeved and connected rotates and is connected with a T-shaped cylinder 803;

[0037] The pressing plate 801 is connected and fixed to the T-shaped cylinder 803. When pulling the T-shaped cylinder 803, the pressing plate 801 is driven to move towards the pressing plate 7 side to extrude the incoming livestock and poultry manure. The liquid extruded and discharged falls onto the top of the partition plate 18 of the sorting cover 1 through the filter plate and is discharged into the liquid collecting tank 19 through the guide of the partition plate 18;

[0038] As the crankshaft 12 continues to rotate, the number of times that livestock and poultry manure can be effectively squeezed gradually decreases, and the water content of livestock and poultry manure tends to be stable. At this time, the stable water content of livestock and poultry manure is broken, and the compression adjustment box 17 controls the rotation of the cam connected to it, driving the arc-shaped adjustment rod 16 connected to the entire cam end to rotate, and at the same time realizing the rotation of the entire eccentric sleeve 15. The eccentric sleeve 15 is abutted and slidably connected with an abutting sleeve rod 14. The abutting sleeve rod 14 actively pushes the abutting sleeve rod 14 due to the change in the center position of the eccentric sleeve 15, resulting in a change in the initial position of the swing arm 13 at the end of the abutting sleeve rod 14.

[0039] like Figure 3 As shown, when the eccentric sleeve wheel 15 rotates to cause the abutment sleeve rod 14 to move upward, the swing arm 13 rotates and pushes the entire connecting rod end pressure plate 7 inward, causing the pressure plate 7 to move inward to increase in depth, and with the rotation of the upper crankshaft 12, the minimum spacing between the pressure plate 17 and the pressure plate 2 801 continues to decrease, and the extrusion force on the livestock and poultry manure is increased, and the solid moisture content after pressing is reduced. Compared with the traditional single-stage pressing, the solid moisture content is usually 50-70%, while the step-by-step pressing can be reduced to below 40%, significantly reducing the subsequent drying or composting costs. At the same time, the step-by-step design avoids the high energy consumption caused by one-time high pressure, and reduces the overall power consumption by gradually increasing the pressure. At the same time, for different manure, such as sticky pig manure and fibrous cow manure, the step-by-step extrusion can optimize the overall dehydration effect by adjusting the pressure and residence time at each level;

[0040] The entire pressure adjustment can be performed step by step while the crankshaft 12 is rotating, which improves the dehydration efficiency of livestock and poultry manure compared to adjustment during shutdown.

[0041] Embodiment 2: Considering that the extrusion is performed on both sides of the polymerization cylinder 4, the feces residue formed is mostly in the form of cakes and cannot be discharged through the bottom opening of the polymerization cylinder 4. Therefore, compared with the fixed structure of the pressing plate 2 801, as shown in FIG. Figure 5 As shown, the entire second pressing plate 801 adopts a double-layer plate surface structure, and a stripping plate 802 is installed inside the second pressing plate 801;

[0042] The stripping plate 802 is divided into two sides, a cutting surface at the front end of the second pressing plate 801 and an inner cylindrical surface of the second pressing plate 801. The cutting surface of the stripping plate 802 is set to increase the overall surface area of the outer side of the second pressing plate 801 to complete the grabbing of the feces residue, so that when the pressing plate 1 7 and the second pressing plate 801 move back and forth, the pressed feces residue is actively driven to move. At the same time, after the installation of the cutting surface, the extruded feces residue is not a complete whole, but an unbroken cake-shaped structure, which can be crushed and separated by simple extrusion in the later stage;

[0043] Regarding the driving of the second pressing plate 801, the sliding column 805 connected to the stripping plate 802 passes through the T-shaped column 803 and extends into the positioning box 9. Figure 5As shown, the inner wall of the entire positioning box 9 is provided with an arc groove 10, and the front end of the arc groove 10 is a straight groove. As the T-shaped column 803 moves to the right, the protrusion on the side wall of the sliding column 805 contacts the arc groove 10 and rotates first, and then moves in the straight groove. Finally, the end of the second pressing plate 801 is separated from the plate 802 and contacts the feces first, and gradually squeezes the feces while sliding.

[0044] When the T-shaped column 803 moves to the left, it slides synchronously with the feces residue, and when the slide column 805 contacts the arc groove 10, the stripper plate 802 rotates on the slide plate 2, and is restricted by the slide plate 2 and the inner wall of the polymerization cylinder 4. The torque generated realizes the automatic crushing of the blocky feces residue, and the feces residue is automatically discharged into the sorting cover 1 after the sleeve 5 rotates at a large angle at the bottom of the polymerization cylinder 4, and is automatically discharged into the slag discharge trough 20 after passing through the partition 18.

[0045] like Figure 5 As shown, each time the sliding column 805 contacts the spring 11 in the positioning box 9, the entire stripping plate 802 will be pushed out. After setting the number of step-by-step extrusions, the automatically controlled partition 18 can move the corresponding liquid and feces to the corresponding liquid collection tank 19 and slag discharge tank 20. The separated placement is convenient for the operator to recycle for secondary processing. The step-by-step compression and aggregation processing equipment is superior to the traditional single-stage processing in dehydration efficiency, energy consumption control, equipment durability and product quality through staged pressure and dynamic regulation. It is particularly suitable for large-scale farms and high-standard resource utilization demand scenarios.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well.
