Description

Technical Field

[0001] This invention belongs to the technical field of dairy farming, and in particular relates to a device for solid-liquid dehydration of cow manure used in dairy farming and its usage method. Background Technology

[0002] With the continuous expansion of modern intensive dairy farms, the average daily manure production per cow can reach 30-50 kg (including urine and flushing water). A medium-sized farm can generate tens or even hundreds of tons of manure daily. Such a massive amount of manure, if not effectively treated, will lead to a series of serious problems, including environmental pollution: direct discharge or leakage of untreated manure will severely pollute groundwater and surface water (leading to eutrophication), release foul-smelling gases (ammonia, hydrogen sulfide, etc.) to pollute the atmosphere, and may spread pathogens; and limitations on land carrying capacity: traditional methods of directly returning liquid manure to the fields are limited by land absorption capacity and seasonal constraints (such as winter and rainy seasons). Excessive application can cause soil salinization, nutrient loss, and excessive nitrate levels in groundwater. At the same time, cow manure is not purely waste but a valuable resource, rich in organic matter, nitrogen, phosphorus, potassium, and other plant nutrients. The solid portion of cow manure has a low moisture content (which can be reduced to about 65% or lower after drying), making it easy to transport and store. It can be used to produce high-quality organic fertilizer (composting), make cow bedding (which can be reused after proper disinfection to reduce costs), and biomass fuel; the liquid portion has a relatively high nutrient concentration and good fluidity. After further processing (such as anaerobic fermentation to produce biogas, aerobic treatment, and storage for maturation), it becomes a high-quality liquid organic fertilizer that can be precisely returned to the field through irrigation systems, resulting in higher nutrient utilization efficiency and reduced reliance on chemical fertilizers. According to the publicly available document CN110052322B, in order to address the above challenges and achieve efficient reduction, harmlessness, and resource utilization of manure, the cow manure solid-liquid dehydration device has become one of the core pieces of equipment in the modern dairy farm manure treatment process.

[0003] Therefore, cow manure currently contains a large amount of sticky organic matter. When using a centrifugal drying device for solid-liquid separation, the manure easily adheres to the inner wall of the screen or spiral blades, forming stubborn clumps that require frequent shutdowns for cleaning. Simultaneously, fibers such as straw and hay become entangled in the spiral shaft or screen gaps, drastically increasing the driving torque and potentially causing motor burnout or damage to transmission components. Furthermore, the manure contains sand and stones, which grind the screen and spiral blades under high-speed centrifugation. Additionally, existing cow manure solid-liquid centrifugal drying devices mostly use a spiral pushing method to control the movement of cow manure within the device, separating the solid and liquid components through a filter. However, this separation method prevents the pushed manure from being effectively compressed, leaving liquid within the manure and hindering complete centrifugation. Therefore, we provide a cow manure solid-liquid centrifugal drying device and its usage method for dairy farming to solve the aforementioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a cow manure solid-liquid spin dryer and its usage method for dairy farming. By using the screw rod and the feed plate in combination, the thoroughness and efficiency of solid-liquid separation of cow manure are improved. At the same time, the scraping strip and the screw rod in combination prevent excessive cow manure residue in the feed cylinder, thereby effectively reducing the occurrence of cow manure blockage inside the feed cylinder.

A scraping strip, which contacts the surface of the screw rod, is located directly below each mounting port. A U-shaped block is slidably installed inside each mounting port. A rotating column, located inside the U-shaped block, is fixed to the upper end face of the scraping strip. The rotating column is fitted onto the shaft of the U-shaped block through a shaft hole on its end face. A torsion spring is installed at the connection between the rotating column and the inner shaft of the U-shaped block.

[0008] The invention is further configured such that the protective cover is located inside the diversion box on the upper surface of the advance cylinder, and the two ends of the protective cover are mounted on the diversion box by bolts.

[0009] The invention is further configured such that a screening frame is fixed to the surface wall of the lower part of the advancing cylinder located to the left of the advancing plate, a drop opening is provided on the surface wall of the lower part of the advancing cylinder located to the right of the advancing plate, and a split plate is fixed to the inner wall of the diversion box located between the drop opening and the screening frame.

[0010] The invention is further configured such that a liquid outlet is provided on the lower surface of the diversion box, which is aligned with the vertical position of the screening screen frame, and a solid outlet is provided on the lower surface of the diversion box, which is aligned with the vertical position of the drop outlet. An inclined plate is bolted to the inner wall of the diversion box located directly above the fixed outlet, and the lower surface of the diversion box is inclined with the right side higher than the left side.

[0011] The invention is further configured such that the front and rear side walls of the mounting strip are provided with adjustment ports that communicate with the interior of the mounting port, the end faces of the mounting strip located at the front and rear of the mounting port are provided with insertion holes that penetrate the interior of each set of adjustment ports, and positioning rods that pass through the interior of the corresponding insertion holes are provided at the positions located at the front and rear of the mounting port.

[0012] The invention is further configured such that both ends of the positioning rod are bolted to locking plates that are connected to both ends of the mounting strip, the locking plates are installed at both ends of the mounting strip by bolts, and the front and rear sides of the U-shaped block are fixed with sliders that are slidably disposed inside the adjustment port.

[0013] The invention is further configured such that the slider is fitted onto the positioning rod through a positioning hole through the surface wall, and a linkage spring fitted onto the positioning rod is fixed to the end face of the slider near the advancing plate.

[0014] The present invention is further configured such that a cylinder passing through the right end face of the advance plate opposite to the screw rod is fixed thereon, an abutment ring is fixed on the end wall of the cylinder outside the advance cylinder, and a movable rod inserted into the cylinder is fixed on the end face of the round block near the advance cylinder.

[0015] A collar block is fitted on the movable rod located outside the advancing cylinder and bolted to the surface wall of the movable rod. The collar block abuts against the end face of the circular block. A return spring is fixed on the movable rod at the end face of the collar block opposite to the end face of the circular block. The return spring abuts against the end face of the abutting ring. A connecting ring is fitted on the surface of the circular cylinder outside the advancing cylinder and abuts against the end face of the advancing cylinder and the abutting ring. A support bar is fixed between the connecting ring and the circular block.

[0016] This invention also provides a method for using a cow manure solid-liquid centrifugation device for dairy farming, which is operated according to the following steps:

[0017] S1: By controlling the motor to work, the motor drives the screw rod inside the feed cylinder to rotate. At this time, the cow manure is poured into the feed cylinder from the inside of the discharge pipe. The rotation of the screw rod will move the cow manure forward in the feed cylinder, thereby controlling the cow manure to be thrown in the feed cylinder, throwing out the liquid in the cow manure, and performing solid-liquid separation of the cow manure.

[0018] S2: After the ejected liquid passes the position of the screening frame, the liquid falls out of the screening frame and into the distribution box located below the screening frame. The ejected liquid is then discharged through the liquid outlet.

[0019] S3: The cow dung inside the feed cylinder will continue to be pushed by the screw rod, and the cow dung will gradually push the feed plate. After the return spring pushes the feed plate in the opposite direction, the cow dung will be squeezed again, and the squeezed liquid will continue to be exposed from the position of the screening screen.

[0020] S4: When cow dung accumulates excessively, it pushes the advancing plate to slide past the drop opening, thus opening the drop opening. The cow dung will fall directly from the drop opening to the upper part of the inclined plate. The inclined plate changes the direction of the cow dung's slide, controlling the cow dung to be discharged from the solid discharge outlet.

[0021] S5: When the screw rod rotates inside the feed cylinder, the screw blades on the screw rod will come into contact with the scraping strip. The scraping strip is pushed by the torsion spring, which controls the scraping strip to stick to the screw blades on the screw rod. Therefore, when the screw rod rotates, the scraping strip will scrape off the cow dung attached to the screw rod.

[0022] The present invention has the following beneficial effects:

[0023] 1. The rotation of the screw blade moves the cow dung forward in the feed cylinder, controlling its movement and causing it to be flung out of the liquid, thus separating the solid and liquid components. Simultaneously, the cow dung gradually pushes against the feed plate, and the return spring pushes the feed plate in the opposite direction, further squeezing the cow dung and separating the solid and liquid components. This improves the thoroughness and efficiency of the solid-liquid separation process.

[0024] 2. When the screw rod rotates inside the feed cylinder, the screw blades on the screw rod will come into contact with the scraping strip. The scraping strip is pushed by the torsion spring, which controls the scraping strip to adhere to the screw blades on the screw rod. Therefore, when the screw rod rotates, the scraping strip will scrape off the cow dung attached to the screw rod, thereby preventing excessive cow dung from adhering to the side wall of the screw blades on the screw rod and preventing excessive cow dung residue in the feed cylinder, thus effectively reducing the situation of cow dung blockage inside the feed cylinder.

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1

[0040] Please see Figure 1 , Figure 2 and Figure 10 This is the first embodiment of the present invention, which provides a cow manure solid-liquid centrifugation device for dairy farming. By using the screw rod 202 in conjunction with the feed plate 301, the thoroughness and efficiency of solid-liquid separation of cow manure are improved. At the same time, the scraping strip 205 and the screw rod 202 work together to prevent excessive cow manure residue in the feed cylinder 201, thereby effectively reducing the occurrence of cow manure blockage inside the feed cylinder 201.

[0041] Specifically, the diversion assembly 100 includes a diversion box 101 and a protective cover 102 located inside the diversion box 101; the spin-drying separation assembly 200 includes a feed cylinder 201 located inside the diversion box 101 and a screw rod 202 located inside the feed cylinder 201; the feed-aid assembly 300 includes a feed plate 301 located inside the feed cylinder 201 and abutting against the end face of the screw rod 202; and the support assembly 400 includes a base frame 401 for supporting the diversion box 101.

[0042] With the above-described structure, the diversion assembly 100 diverts the discharged solid cow dung and liquid cow dung. Simultaneously, the protective cover 102 protects the feed cylinder 201 inside the diversion box 101. When the screw rod 202 pushes the cow dung through the feed cylinder 201, the feed plate 301, also located inside the feed cylinder, counteracts the force of the screw rod 202, pushing the cow dung in the opposite direction. This allows for multi-stage solid-liquid separation of the cow dung, ensuring thorough solid-liquid separation. Furthermore, the base frame 401 supports the diversion box 101, ensuring its stable operation.

[0043] according to Figure 3 , Figure 4 , Figure 7 and Figure 8An installation port 201a is provided on the surface of the upper part of the feed cylinder 201. An installation strip 204 is installed inside the installation port 201a by bolts. The lower end face of the installation strip 204 has a moving port 204a at the position between two adjacent screws of the screw rod 202. A discharge pipe 201b is fixed on the upper part of the surface of the feed cylinder 201 located to the left of the diversion box 101. A round block 302 is provided at the right of the diversion box 101. The base frame 401 is connected to the diversion box 101 by bolts. The bolt connection is provided with a scraping strip 205 located directly below each set of mounting ports 201a, which is in contact with the surface of the screw blade of the screw rod 202. A U-shaped block 206 is slidably arranged inside each mounting port 201a. A rotating column 205a located inside the U-shaped block 206 is fixed to the upper end face of the scraping strip 205. The rotating column 205a is sleeved on the shaft of the U-shaped block 206 through a shaft hole opened on the end face. A torsion spring 206c is installed at the connection between the rotating column 205a and the inner shaft of the U-shaped block 206.

[0044] When using the above-described structure, the rotation of the screw rod 202 moves the cow dung forward within the feed cylinder 201, thus controlling the cow dung to be flung out within the feed cylinder 201, separating the liquid from the dung and achieving solid-liquid separation. Simultaneously, the cow dung gradually pushes against the feed plate 301, and the return spring 303a pushes the feed plate 301 in the opposite direction, cooperating with the screw rod 202 to squeeze the cow dung in a relative direction, further separating the solid and liquid components. Meanwhile, the screw... When the rod 202 rotates inside the feed cylinder 201, the screws on the screw rod 202 will come into contact with the scraping strip 205. The torsion spring 206c forces the scraping strip 205 to rotate around the rotating column 205a, so that it always keeps in close contact with the screw surface of the screw rod 202. Therefore, when the screw rod 202 rotates, the scraping strip 205 will scrape off the cow dung attached to the screw rod 202, thereby preventing excessive cow dung from adhering to the side wall of the screw of the screw rod 202 and preventing excessive cow dung from remaining in the feed cylinder 201.

[0045] Furthermore, according to Figure 2 , Figure 10 It is known that the left end of the screw rod 202 passes through the side wall of the advance cylinder 201 via a bearing and is fixed to the connecting plate 202a. The upper end face of the base frame 401 is fixed with a motor 402 that is connected to the drive of the connecting plate 202a. The left and right parts of the lower end face of the base frame 401 are fixed with pulley frames 403. By controlling the operation of the motor 402, the motor 402 will synchronously drive the screw rod 202 to rotate in the advance cylinder 201 via the connecting plate 202a. When it is necessary to move the device, it can be flexibly pushed on the ground through the pulley frames 403, which facilitates movement on the ground and makes it easy to adjust the position of the device.

[0046] Furthermore, according to Figure 2 and Figure 5It is known that a screening frame 203 is fixed to the lower surface of the feed cylinder 201 located to the left of the feed plate 301, and a drop outlet 201c is opened on the lower side wall of the feed cylinder 201 located to the right of the feed plate 301. A split plate 101a is fixed to the inner wall of the diversion box 101 located between the drop outlet 201c and the screening frame 203. The screening frame 203 separates the solid and liquid inside the feed cylinder 201. The drop outlet 201c ensures that the cow manure falls into the diversion box 101, while the split plate 101a separates the solid discharge outlet 101b and the liquid discharge outlet 101c to prevent the solid cow manure and liquid from mixing again.

[0047] It should be noted that when controlling motor 402, the plug on motor 402 must be connected to an external power source to control the operation of motor 402. At the same time, when separating cow dung, the pulley frame 403 needs to be limited to prevent the entire device from deviating through the pulley frame 403. Furthermore, before solid-liquid separation, two sets of recycling boxes need to be set directly below the corresponding solid discharge port 101b and liquid discharge port 101c to separate and recycle the discharged solid cow dung and liquid.

[0048] Example 2

[0049] Please see Figure 5 Based on Example 1, this example prevents cow dung liquid from splashing out from the top of the distribution box 101 by installing the protective cover 102 in the distribution box 101 that is progressively above it.

[0050] Specifically, the protective cover 102 is located inside the diversion box 101 on the upper surface of the advance cylinder 201, and both ends of the protective cover 102 are bolted to the diversion box 101.

[0051] With the above-described structure, the protective cover 102 protects the infeed cylinder 201 inside the diversion box 101. At the same time, after the liquid in the cow dung enters the diversion box 101, the protective cover 102 blocks the liquid in the diversion box 101, thus preventing the cow dung liquid from splashing out from the top of the diversion box 101.

[0052] Example 3

[0053] Please see Figure 5 Based on Example 1, this example uses an inclined plate 103 to prevent solid cow dung from falling directly to the bottom of the diversion box 101, thereby reducing the impact force generated by the falling solid cow dung.

[0054] Specifically, a liquid outlet 101c is provided on the lower surface of the diversion box 101, which is aligned with the vertical position of the screening frame 203. A solid outlet 101b is provided on the lower surface of the diversion box 101, which is aligned with the vertical position of the drop outlet 201c. An inclined plate 103 is bolted to the inner wall of the diversion box 101, which is located directly above the fixed outlet. The lower surface of the diversion box 101 is inclined with the right side higher than the left side.

[0055] By using the above structure, the liquid outlet 101c and the solid outlet 101b are separated, allowing for the separate recycling of solid-liquid separated cow dung and preventing mixing between the liquid and solid. At the same time, the inclined plate 103 is installed in the diversion box 101, thereby blocking and buffering the falling solid cow dung, preventing it from falling directly to the bottom of the diversion box 101, and reducing the impact force generated by the falling solid cow dung.

[0056] Example 4

[0057] Please see Figure 7 , Figure 8 and Figure 9 Based on Example 1, this example uses the U-shaped block 206, the linkage spring 207a and the scraping strip 205 to move the U-shaped block 206 toward the screw blade of the screw rod 202, ensuring that the scraping strip 205 is always in contact with the side wall of the screw rod 202.

[0058] Specifically, the front and rear side walls of the mounting strip 204 are provided with adjustment ports 204b that communicate with the interior of the mounting port 201a. The end faces of the mounting strip 204 located in front of and behind the mounting port 201a are provided with insertion holes 204c that penetrate the interior of each set of adjustment ports 204b. Positioning rods 207 are provided in front of and behind the mounting port 201a and pass through the interior of the corresponding insertion holes 204c. The two ends of the positioning rods 207 are bolted to locking plates 207b that connect to the two ends of the mounting strip 204. The locking plates 207b are installed at the two ends of the mounting strip 204 by bolts. The front and rear sides of the U-shaped block 206 are fixed with sliders 206a that are slidably disposed in the interior of the adjustment ports 204b. The sliders 206a are sleeved on the positioning rods 207 through positioning holes 206b that penetrate the surface wall. The end faces of the sliders 206a near the advancing plate 301 are fixed with linkage springs 207a that are sleeved on the positioning rods 207.

[0059] With the above-described structure, when the screw rod 202 rotates, the spiral screws push the scraping strip 205, causing the scraping strip 205 to rotate around the rotating column 205a as its axis. This tilts the scraping strip 205, ensuring stable contact between the scraping strip 205 and the side of the screw on the screw rod 202. Simultaneously, the rotation of the screw rod 202 controls the movement of the U-shaped block 206 within the mounting opening 201a, allowing the U-shaped block 206 to move synchronously through the rotating column 205a. 05a drives the scraping strip 205 to move, and at the same time, the U-shaped block 206 drives the slider 206a to move on the positioning rod 207 through the positioning hole 206b. When the slider 206a moves in the adjustment port 204b, it will compress the linkage spring 207a at the same time. Therefore, through the pushing of the slider 206a by the linkage spring 207a, the U-shaped block 206 moves towards the screw blade direction of the screw blade rod 202, ensuring that the scraping strip 205 is in contact with the side wall of the screw blade rod 202 at all times.

[0060] Example 5

[0061] Please see Figure 2 , Figure 3 and Figure 6 Based on Embodiment 1, this embodiment uses a reset spring 303a to ensure that the advancing plate 301 can autonomously reset to its initial position.

[0062] Specifically, a cylinder 301a, passing through the right end face of the advance plate 301 opposite to the screw rod 202, is fixed to the end face of the advance plate 301. An abutment ring 301b is fixed to the end wall of the cylinder 301a outside the advance plate 201. A movable rod 302b, inserted into the cylinder 301a, is fixed to the end face of the block 302 near the advance plate 201. A collar block 30, bolted to the surface wall of the movable rod 302b, is fitted onto the movable rod 302b outside the advance plate 201. 3. The collar block 303 abuts against the end face of the round block 302. The end face of the collar block 303 opposite to that of the round block 302 is fixed with a return spring 303a sleeved on the movable rod 302b. The return spring 303a abuts against the end face of the abutting ring 301b. The outer side of the round cylinder 301a outside the advancing cylinder 201 is fitted with a connecting ring 302c that abuts against the end face of the advancing cylinder 201 and the abutting ring 301b. A support bar 302a is fixed between the connecting ring 302c and the round block 302.

[0063] With the above-described structure, when the advance plate 301 is pushed and moved by cow dung, the advance plate 301 will move along the movable rod 302b via the cylinder 301a. At the same time, the cylinder 301a will compress the return spring 303a via the abutment ring 301b. Therefore, when all the cow dung inside the advance cylinder 201 is discharged into the drop outlet 201c, the return spring 303a will push the cylinder 301a and the advance plate 301 back to their initial positions inside the advance cylinder 201.

[0064] Example 6

[0065] This invention also provides a method for using a cow manure solid-liquid centrifugation device for dairy farming, which is operated according to the following steps:

[0066] S1: By controlling the operation of motor 402, motor 402 drives the screw rod 202 inside the feed cylinder 201 to rotate. At this time, cow manure is poured from the inside of the discharge pipe 201b into the feed cylinder 201. The rotation of the screw rod 202 will move the cow manure forward in the feed cylinder 201, thereby controlling the cow manure to be flung in the feed cylinder 201, flinging out the liquid in the cow manure, and performing solid-liquid separation of cow manure.

[0067] S2: After the ejected liquid passes the position of the screening frame 203, the liquid falls out from the position of the screening frame 203 and falls into the diversion box 101 located below the screening frame 203, and is discharged through the liquid outlet 101c.

[0068] S3: The cow dung inside the feed cylinder 201 will continue to be pushed by the screw rod 202, and the cow dung will gradually push the feed plate 301. After the return spring 303a pushes the feed plate 301 in the opposite direction, the cow dung will be squeezed again, and the squeezed liquid will continue to be exposed from the position of the screening frame 203.

[0069] S4: When the cow dung accumulates to an excessive amount, the cow dung pushes the advancing plate 301 to slide past the drop opening 201c, thereby opening the drop opening 201c. The cow dung will fall directly from the drop opening 201c to the upper end of the inclined plate 103. The inclined plate 103 changes the direction of the cow dung's fall, controlling the cow dung to be discharged from the solid discharge outlet 101b.

[0070] S5: When the screw rod 202 rotates inside the advance cylinder 201, the screws on the screw rod 202 will come into contact with the scraping strip 205. The scraping strip 205 is pushed by the torsion spring 206c, which controls the scraping strip 205 to stick to the screws on the screw rod 202. Therefore, when the screw rod 202 rotates, the scraping strip 205 will scrape off the cow dung attached to the screw rod 202.
