Description

Technical Field

[0001] The present invention belongs to the technical field of manure treatment, and in particular relates to an automatic dry-wet separation mechanical device for manure in cattle and sheep farms. Background Art

[0002] Large-scale cattle and sheep farms generate several tons or even dozens of tons of manure every day. If not handled properly, it will not only cause serious pollution to the soil, water and air around the farms, but also breed a large number of pathogens, threatening the health of livestock and poultry and public health safety. Therefore, scientific treatment and resource utilization of cattle and sheep manure has become an urgent need to ensure the green development of the breeding industry and achieve a win-win situation of ecological and economic benefits.

[0003] Solid-liquid separation of cattle and sheep manure is a key pre-step to achieve resource utilization and harmless treatment of manure. Through solid-liquid separation, the separated solid matter can be used as high-quality organic fertilizer raw materials to improve soil and promote crop growth. The separated liquid part can be returned to the field as liquid fertilizer after purification, or used for energy utilization such as biogas fermentation. It can not only effectively reduce the pollution of manure to the environment, but also transform waste into valuable resources, realizing the circular economy development of the breeding industry.

[0004] However, in actual use, some of the common cattle and sheep farm manure solid-liquid separation equipment currently on the market only adopts a single separation method, such as relying solely on gravity sedimentation or simple mechanical extrusion, resulting in low dry-wet separation efficiency and excessively high water content of the dry matter after separation, which not only affects the subsequent production quality of organic fertilizers, but also increases transportation and storage costs.

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0028] Example 1: Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 , a mechanical equipment for automatic dry-wet separation of manure and sewage in cattle and sheep farms, comprising a tank body 1 with an opening, and also comprising: a partition plate 103 with a leakage hole, fixedly connected to the tank body 1, wherein a separation chamber 101 is provided above the partition plate 103 in the tank body 1, and a purification chamber 102 is provided below, and a purification unit for purifying the separated liquid is provided in the purification chamber 102; a filter cartridge 2 arranged in the separation chamber 101, rotatably connected to the partition plate 103; a pressure plate 203, which is lifted and connected to the upper end portion of the tank body 1 and matches the inner diameter of the filter cartridge 2; a hollow cavity 7, arranged in the pressure plate 203, wherein a plurality of air nozzles 701 connected to the hollow cavity 7 are equidistantly provided on the circumference of the lower end surface of the pressure plate 203; an air supply pipe 703, which is connected to the hollow cavity 7.

[0029] A mounting frame 201 is fixedly mounted on the tank body 1 , an electric telescopic rod 202 is fixedly connected to the mounting frame 201 , a rotating seat 204 is rotatably connected to the pressure plate 203 , and the electric telescopic rod 202 is fixedly connected to the rotating seat 204 .

[0030] A booster pump 702 is fixedly connected to the tank body 1, and the output end of the booster pump 702 is connected to the air inlet end of the air pipe 703. The air outlet end of the air pipe 703 is connected to the hollow cavity 7 through a rotary joint. The rotary joint is arranged on the pressure plate 203, and an activated carbon filter is arranged in the input end of the booster pump 702.

[0031] The purification unit includes a sleeve 301 and an activated carbon filter plate 303 and a zeolite molecular sieve plate 304 arranged in the sleeve 301. A connecting ring 3 is fixedly connected to the cavity wall of the purification chamber 102. The sleeve 301 is threadedly connected to the connecting ring 3. The lower end of the tank body 1 is open and communicated with the purification chamber 102. The lower end of the tank body 1 is disassembled and connected to the cover plate 4 by a fixing bolt 401.

[0032] A liquid circulation pump 5 is fixedly installed on the side wall of the tank body 1. The input end of the liquid circulation pump 5 is connected to the lower end of the purification chamber 102, and the output end is connected to the upper end of the purification chamber 102 through an infusion tube 501. The liquid outlet end of the infusion tube 501 is located above the purification unit.

[0033] The second infusion tube 502 is provided in a spiral shape. A plurality of liquid spray holes 503 facing the purification unit are provided on the second infusion tube 502. The second infusion tube 502 is connected to the first infusion tube 501.

[0034] The partition plate 103 is rotatably connected to a rotating shaft 6, which passes through one end of the separation chamber 101 and is fixedly connected to the filter cartridge 2. The rotating shaft 6 passes through one end of the infusion tube 501 and is fixedly connected to an impeller 601, which is fixedly connected to the partition plate 103.

[0035] When in use, put the manure from the cattle and sheep farm into the filter cartridge 2, start the electric telescopic rod 202, and the telescopic rod extends to drive the pressure plate 203 to descend into the filter cartridge 2. The pressure plate 203 applies pressure to the manure in the filter cartridge 2, squeezing out the liquid in the manure, and realizing the preliminary dry-wet separation of the manure in the filter cartridge 2. The separated liquid flows into the separation chamber 101 through the filter holes of the filter cartridge 2, and then flows into the purification chamber 102 through the leakage hole on the partition plate 103. The liquid flowing into the purification chamber 102 enters the sleeve 301 and passes through the activated carbon filter from top to bottom. The core plate 303, zeolite molecular sieve plate 304, and activated carbon filter core plate 303 adsorb impurities such as organic matter and pigments in the liquid. The zeolite molecular sieve plate 304 further removes odors and adsorbs harmful ions. The purified liquid is temporarily stored at the bottom of the purification chamber 102. In this process, the pressure plate 203 applies pressure to perform preliminary dry-wet separation. At the same time, the characteristics of activated carbon and zeolite molecular sieve are used to preliminarily purify the liquid, effectively reducing the liquid content in the dry matter, improving the quality of the dry matter, and preliminarily purifying the separated liquid, reducing the burden of subsequent processing.

[0036] Start the liquid circulation pump 5, and the liquid temporarily stored in the purification chamber 102 after purification is sucked in, flows into the liquid infusion pipe 1 501 and into the liquid infusion pipe 2 502, and then is evenly sprayed on the purification unit from the liquid spray hole 503, and then circulates and purifies again from top to bottom through the activated carbon filter plate 303 and the zeolite molecular sieve plate 304, so that the purification is more complete;

[0037] At the same time, when the liquid flows through the infusion tube 501, the impact impeller 601 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the filter cartridge 2 to rotate. The rotation of the filter cartridge 2 generates centrifugal force. Under the action of centrifugal force, the squeezed liquid is more easily separated from the feces and moves toward the wall of the filter cartridge 2, increasing the chance of the liquid contacting the filter holes, so that more liquid is discharged from the filter cartridge 2 through the filter holes and flows into the purification chamber 102 through the leakage hole on the partition plate 103 to participate in the circulation purification. The circulation purification process improves the efficiency and quality of liquid purification and can better remove impurities and harmful substances in the liquid. Among them, centrifugal assisted separation further improves the dry-wet separation effect and reduces the water content of dry matter;

[0038] At the same time, the booster pump 702 is started, and the booster pump 702 delivers gas to the hollow cavity 7 through the air pipe 703 and sprays it out through the air nozzle 701. The gas sprayed by the air nozzle 701 can blow the feces and sewage in the filter cartridge 2, causing its position and state to change. The structure of part of the feces and sewage that was originally compacted and not conducive to the outflow of liquid is disrupted, and the contact area between the feces and sewage and the filter holes of the filter cartridge 2 is increased, allowing more liquid to flow out smoothly through the filter holes, thereby improving the degree of solid-liquid separation, making the water content of the dry matter after separation lower, improving the quality of the dry matter, and being more conducive to subsequent resource utilization as organic fertilizer raw materials. At the same time, the blowing of gas can accelerate the flow of liquid in feces and sewage, prompting the liquid to move faster toward the wall of the filter cartridge 2 and be discharged, reducing the time the liquid stays in feces and sewage, speeding up the speed of the entire solid-liquid separation, improving the working efficiency of the equipment, and being able to process more feces and sewage per unit time.

[0039] In summary, through the combination of pressure from the pressure plate 203, centrifugal force, and air jet assistance, efficient dry-wet separation of manure and sewage is achieved, reducing the moisture content of the dry matter. At the same time, the liquid circulation purification process, combined with the adsorption characteristics of activated carbon and zeolite molecular sieves, effectively improves the efficiency and quality of liquid purification, reduces environmental pollution, and facilitates the subsequent utilization of dry matter and the discharge or reuse of liquid.

[0040] The energy generated by the operation of the liquid circulation pump 5 is used to drive the filter cartridge 2 to rotate, without the need for an additional power device, thus saving energy.

[0041] It should be noted that the air pipe 703 is a stretchable and shrinkable hose, so the air pipe 703 will not interfere with the up and down movement of the pressure plate 203.

[0042] Example 2: Reference Figure 1 、 Figure 2 、 Figure 4 , an automatic dry-wet separation mechanical device for manure in cattle and sheep farms, which is basically the same as Example 1, furthermore, a pressing ring arranged in an annular shape is fixedly mounted on the outer wall of the sleeve 301, and a sealing gasket 302 is provided on the pressing ring, and the sealing gasket 302 is in contact with the underlying surface of the connecting ring 3;

[0043] The operator installs the activated carbon filter plate 303 and the zeolite molecular sieve plate 304 into the sleeve 301, then aligns the sleeve 301 with the connecting ring 3 in the purification chamber 102, and rotates the sleeve 301 to thread it into the connecting ring 3. As the sleeve 301 is gradually tightened, the sealing gasket 302 on the pressing ring contacts and is squeezed by the underlying surface of the connecting ring 3, elastically deforming to fill the gap between the two and form a seal.

[0044] During the operation of the device, the separated liquid flows into the purification chamber 102 from the leakage hole of the partition plate 103 and enters the sleeve 301 for purification. Due to the sealing effect of the sealing gasket 302, the liquid can only be purified by the purification unit and cannot leak from the connection between the sleeve 301 and the connecting ring 3;

[0045] In summary, the effective sealing of the sealing gasket 302 prevents the liquid in the purification chamber 102 from leaking from the connection between the sleeve 301 and the connecting ring 3, ensuring that all liquids must be processed through the purification unit, thereby ensuring the integrity of the purification effect. If the liquid leaks, the liquid that has not been fully purified may directly enter the bottom of the purification chamber 102, resulting in the discharged liquid not meeting the standards and polluting the environment.

[0046] Example 3: Reference Figure 2 、 Figure 4 , an automatic dry-wet separation mechanical device for manure in cattle and sheep farms, which is basically the same as Example 1, furthermore, a drain pipe 402 connected to the purification chamber 102 is provided on the cover plate 4, and a solenoid valve is provided on the drain pipe 402;

[0047] When the solid-liquid separation of feces is completed and the liquid in the purification chamber 102 reaches a suitable purification level or needs to be discharged, the solenoid valve on the drain pipe 402 is opened, and the purified liquid is discharged through the drain pipe 402;

[0048] When the purification unit filter plate needs to be replaced, unscrew the fixing bolt 401 to remove the cover plate 4, then rotate the sleeve 301 to remove it from the connecting ring 3, replace the internal filter plate, and after separation is completed, the electric telescopic rod 202 retracts to make the pressure plate 203 rise and reset, and the dry matter in the filter cartridge 2 can be taken out.

[0049] Example 4: Reference Figure 2 , an automatic dry-wet separation mechanical device for manure in cattle and sheep farms, which is basically the same as Example 1, furthermore, a plurality of balls 602 are equidistantly arranged on the circumference of the partition plate 103, and the balls 602 are in contact with the lower end surface of the filter cartridge 2;

[0050] Utilizing the principle that rolling friction is less than sliding friction, balls 602 are arranged between the lower end surface of the filter cartridge 2 and the partition disc 103. When the filter cartridge 2 rotates driven by the rotating shaft 6, the original sliding friction between the lower end surface of the filter cartridge 2 and the partition disc 103 is converted into rolling friction with the balls 602. The balls 602 roll freely in the mounting groove, dispersing the resistance during the rotation of the filter cartridge 2 into the rolling motion of each ball 602, greatly reducing the rotation resistance. Moreover, the balls 602 are evenly distributed, which can evenly support the lower end surface of the filter cartridge 2, so that the filter cartridge 2 is subjected to balanced force during rotation, thereby ensuring the stability of rotation.

[0051] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as above with the preferred embodiment, it is not intended to limit the present invention.
