Description

Technical Field

[0001] The present invention relates to the technical field of manure treatment, and more particularly to a self-cleaning livestock manure treatment device. Background Art

[0002] In the process of separating feces and urine by existing manure treatment devices, most of them directly add manure into the filter cylinder for separation. However, during the separation process, feces will adhere to the inner wall of the filter cylinder, affecting the subsequent discharging effect of feces. At the same time, the feces adhering to the inner wall of the filter cylinder will also affect the separation efficiency of manure.

[0003] Chinese Patent Publication No. CN222498928U discloses a livestock manure treatment device, including a treatment tank, a feed bin, a water outlet, a discharge outlet, a filtering mechanism and a crushing mechanism; a filtering cavity and a crushing cavity are opened in the treatment tank, and a connection port is opened between the filtering cavity and the crushing cavity; the feed bin is opened on the inner top wall of the filtering cavity; the water outlet is opened on the side wall of the filtering cavity, and the discharge outlet is opened on the side wall of the crushing cavity; the filtering mechanism is arranged in the filtering cavity for separating feces and sewage; the crushing mechanism is arranged in the crushing cavity for crushing feces.

[0004] The above solution realizes the separation of feces and urine through centrifugal force. However, under the action of centrifugal force, the separated feces are difficult to discharge from the center of the filter barrel. If the separated feces need to be discharged, the filter barrel needs to stop rotating, resulting in the necessity to stop the filter barrel when discharging feces. Moreover, since the bottom of the filter barrel is a horizontal end face structure, when the mixture of feces and urine is just put in, part of the urine can also be discharged from the center of the filter barrel, resulting in incomplete separation of feces and urine. At the same time, when cleaning the filter barrel, the scraper cannot clean the blocked filter holes on the filter barrel. As the number of blocked filter holes increases with use, the filtering performance of the filter barrel continuously decreases. Summary of the Invention

[0017] 1.

[0031] To further understand the features, technical means, and the specific purposes and functions achieved by the present invention, the following will describe the present invention in further detail in combination with the accompanying drawings and specific implementation manners.

[0032] Refer to Figure 1 , Figure 2 and Figure 4 - Figure 7: A self-cleaning livestock manure treatment device, including a treatment shell 1 with a feeding port 11 opened at the upper part; a rotatable water-permeable rotating belt 2 is arranged in the treatment shell 1. The upper part of the rotating belt 2 is arranged in a undulating structure, and the undulating structure is divided into a concave area 21 and a horizontal area 22 in the horizontal direction. The feeding port 11 is located directly above the concave area 21. The lower part of the rotating belt 2 is a discharging area 23. A water storage tank 24 for storing the urine separated from the concave area 21 and the horizontal area 22 is horizontally arranged in the inner ring of the rotating belt 2. After the manure is put into the feeding port 11, it first passes through the concave area 21 for preliminary solid-liquid separation, then passes through the horizontal area 22 for secondary solid-liquid separation, and finally the feces attached to the rotating belt 2 are discharged from the discharging area 23.

[0033] There are various structures of existing livestock manure treatment devices, such as hanging cloth type, centrifugal type, etc. Among them, the hanging cloth type manure treatment device vertically arranges the cloth for filtration and arranges multiple in the horizontal direction. The manure is discharged onto the cloth, the feces adhere to the cloth, and the urine is discharged from below the cloth. However, the hanging cloth type manure treatment device cannot be applied to the manure containing a large amount of feces because the amount of feces intercepted by the cloth is limited. In the face of a large amount of feces, the cloth cannot completely intercept the feces, and all the cloths need to be replaced and cleaned regularly, which takes a long time and has a large workload. The centrifugal type manure treatment device can overcome the above problems and is suitable for treating a large amount of manure. During the treatment process, there is less feces in the separated urine and the separation effect is better. However, due to the action of centrifugal force, the feces separated from the urine usually remain in the centrifugal type manure treatment device. When the feces need to be removed, the centrifugal type manure treatment device needs to stop rotating so that the feces are no longer affected by the centrifugal force, but this results in the manure not being able to be continuously put into the manure treatment device, and there is still the problem of low treatment efficiency. At the same time, the core filtering component in the existing centrifugal type manure treatment device is mainly a filter screen. The manure moves to the filter screen under the action of centrifugal force, the urine passes through the filter screen, and the feces remain on the filter screen. Some feces will block the mesh holes of the filter screen. Most of the existing cleaning devices clean the filter screen through a cleaning brush, but the cleaning brush cannot clean the feces blocked on the mesh holes. After long-term use, more and more mesh holes on the filter screen will be blocked, resulting in a continuous decline in the filtering performance of the filter screen.

[0034] In order to avoid the above situation, the structure of the existing manure treatment device is redesigned so that the manure treatment device can not only effectively separate the manure containing a large amount of feces, but also automatically discharge the separated feces without stopping the machine, ensuring that the manure can be continuously put into the manure treatment device and improving the treatment efficiency. The specific structure and working process of the manure treatment device of the present invention are as follows:

[0035] A plurality of driving wheels 12 are arranged in the processing shell 1. The driving wheels 12 are located on the inner ring side of the rotating belt 2 and are used to drive the rotating belt 2 to rotate. A rotating driver 13 for driving the driving wheel 12 to rotate is arranged on one of the driving wheels 12. The rotating driver 13 is preferably a servo motor.

[0036] During use, the rotating belt 2 is continuously rotated in the processing shell 1. The fecal sewage is put into the processing shell 1 from the feeding port 11. The fecal sewage entering the processing shell 1 is received by the rotating belt 2, and at this time, the fecal sewage is located in the recessed area 21. Since the rotating belt 2 has water permeability, the fecal sewage falling into the recessed area 21 undergoes preliminary solid-liquid separation, that is, the urine passes through the rotating belt 2 and falls into the water storage tank 24, while the feces are intercepted by the rotating belt 2. As the rotating belt 2 rotates, the feces gradually transfer from the recessed area 21 to the horizontal area 22. When the feces pass through the horizontal area 22, the feces located on the horizontal area 22 are spread out, and the urine remaining in the feces undergoes secondary separation in the horizontal area 22. The separated urine falls into the water storage tank 24 for storage. As the rotating belt 2 rotates, the feces passing through the horizontal area 22 adhere to the surface of the rotating belt 2 and move synchronously with the rotating belt 2. The rotating belt 2 drives the feces passing through the horizontal area 22 to the discharging area 23. Since the rotating belt 2 undergoes multiple bends during the process of rotating from the horizontal area 22 to the discharging area 23, the feces adhering to the rotating belt 2 become loose. When the feces are located in the discharging area 23, the feces adhering to the rotating belt 2 are below the rotating belt 2, and the feces fall off from the rotating belt 2 under the action of their own gravity. The rotating belt 2 at the discharging area 23 discharges the feces and then rotates towards the recessed area 21, repeating the cycle. Compared with the centrifugal fecal sewage treatment equipment, through the rotation of the rotating belt 2, the feces can be discharged without stopping the operation of the rotating belt 2 when separating the fecal sewage, improving the separation efficiency. It should be noted that the fecal sewage is composed of urine and feces. The recessed area 21 and the horizontal area 22 formed on the upper side of the rotating belt 2 are necessary. If only the recessed area 21 is set, a large amount of feces will accumulate at the bottom of the recessed area 21, resulting in a reduction in the filtering effect, and the feces output from the recessed area 21 will have a high water content. If only the horizontal area 22 is set, the fecal sewage can flow freely after falling into the horizontal area 22. Compared with only setting the recessed area 21, the horizontal area 22 has a better filtering effect on the fecal sewage, but it is easy for the upper-layer fecal sewage to directly fall into the discharging area 23 along with the rotating belt 2. Therefore, by combining the recessed area 21 and the horizontal area 22 and making the feces first enter the recessed area 21, it not only avoids the situation where the fecal sewage directly drains into the discharging area 23 due to free flow but also ensures the filtering effect on the fecal sewage.

[0037] By arranging a continuously rotating conveyor belt 2 inside the processing shell 1, a concave area 21 and a horizontal area 22 are formed on the upper conveyor belt 2, and a discharge area 23 is formed on the lower conveyor belt 2. The feeding port 11 is located directly above the concave area 21. During processing, the fecal sewage is first put into the concave area 21 through the feeding port 11. The concave area 21 is used to prevent the fecal sewage from flowing randomly. Then, the conveyor belt 2 drives the feces preliminarily filtered in the concave area 21 to the horizontal area 22 for secondary filtration, improving the effect of solid-liquid separation. The urine passes through the conveyor belt 2 and is collected by the water storage tank 24. The feces are conveyed by the conveyor belt 2 to the discharge area 23 and discharged, enabling the conveyor belt 2 to not only filter the fecal sewage but also discharge the feces in a timely manner. In summary, the present invention can effectively separate the fecal sewage containing a large amount of feces and automatically discharge the separated feces without stopping the machine, ensuring that the fecal sewage can be continuously input into the fecal sewage treatment equipment and improving the processing efficiency.

[0038] Refer to Figure 7 : The width cross-section of the conveyor belt 2 is jointly composed of a water-filtering part 25 and two rotating parts 26. The two rotating parts 26 are respectively located on both sides of the water-filtering part 25, and the upper end surface of the rotating part 26 is higher than the upper end surface of the water-filtering part 25. The water-filtering part 25 has water-filtering properties and is used to receive fecal sewage.

[0039] The water-filtering part 25 and the rotating part 26 jointly form the conveyor belt 2, and the fecal sewage is received through the water-filtering part 25, avoiding the situation where the feces in the fecal sewage are driven by the urine to the joint between the conveyor belt 2 and the inner wall of the processing shell 1, and then the feces are discharged into the water storage tank 24 through the joint.

[0040] Refer to Figure 7 : A plurality of lifting plates 251 for lifting the feces in the concave area 21 are uniformly and fixedly arranged on the outer periphery of the conveyor belt 2. The lifting plates 251 are fixedly arranged on the water-filtering part 25.

[0041] The lifting plates 251 are also arranged on the water-filtering part 25. When the lifting plates 251 rotate with the conveyor belt 2 and pass through the concave area 21, the lifting plates 251 can push and carry away the remaining feces in the concave area 21, avoiding the situation of feces accumulation in the concave area 21 and also avoiding the situation where the urine cannot pass through the conveyor belt 2 smoothly and accumulates on the upper layer of the feces due to the feces accumulation, and further avoiding the accumulated urine driving the feces to the joint between the conveyor belt 2 and the inner wall of the processing shell 1.

[0042] Refer to Figure 6 、 Figure 7 and Figure 9 : A pressing wheel 212 is rotatably arranged above the conveyor belt 2, and a supporting wheel 211 is rotatably arranged on one side of the pressing wheel 212. The supporting wheel 211 is located in the inner ring of the conveyor belt 2 and is in rolling cooperation with the inner ring side of the conveyor belt 2. The center height of the pressing wheel 212 is lower than the center height of the supporting wheel 211.

[0043] By means of the supporting wheel 211 and the pressing wheel 212, and making the rotating belt 2 wind around the supporting wheel 211 and the pressing wheel 212 in sequence, the recessed area 21 is formed.

[0044] Refer to Figure 7 and Figure 9 : An elevating frame 213 that moves in the vertical direction is provided at the end of the pressing wheel 212. The pressing wheel 212 presses on the rotating part 26 of the rotating belt 2 by its own gravity, and the elevating frame 213 moves up and down synchronously with the pressing wheel 212.

[0045] The pressing wheel 212 presses on the rotating belt 2 by its own gravity, so that the pressing wheel 212 is always in a taut state, avoiding the situation that the rotating belt 2 is sunken at the horizontal area 22 due to long-term use.

[0046] Refer to Figure 9 and Figure 10 : An air extraction shell 221 is provided on the inner ring side of the rotating belt 2 corresponding to the horizontal area 22. An air extraction port is provided at the upper part of the air extraction shell 221. The air extraction port is located directly below the rotating belt 2 and contacts the lower part of the rotating belt 2. A fan 222 for extracting the air in the air extraction shell 221 is provided on the air extraction shell 221.

[0047] When the fan 222 extracts the air in the air extraction shell 221, the air in the upper layer of the horizontal area 22 passes through the rotating belt 2 vertically from top to bottom. The flowing air takes away the urine in the feces at the horizontal area 22, improving the solid-liquid separation effect at the horizontal area 22.

[0048] Refer to Figure 1 - Figure 10 : The air extraction shell 221 extends into the water storage tank 24, and the bottom of the air extraction shell 221 is immersed in the urine in the water storage tank 24.

[0049] When the fan 222 is operating, the fan 222 sucks the urine in the horizontal area 22 into the air extraction shell 221. The air extraction shell 221 guides the urine into the water storage tank 24, so that the bottom of the air extraction shell 221 extends into the urine in the water storage tank 24, ensuring that the urine can seal the bottom of the air extraction shell 221. When the fan 222 extracts air through the air extraction shell 221, the air can only be sucked in from the air extraction port of the air extraction shell 221, improving the suction at the air extraction port.

[0050] Refer to Figure 7 and Figure 8: A partition plate 2211 that horizontally and fixedly divides the air extraction housing 221 into an upper cavity and a lower cavity is provided inside the air extraction housing 221. The liquid level of the urine in the water storage tank 24 is located below the partition plate 2211. The fan 222 is located in the upper cavity. A water permeable opening 2212 is vertically penetrated through the partition plate 2211. A floating buoy 2213 is movably arranged vertically below the water permeable opening 2212. When the floating buoy 2213 rises, it can block the water permeable opening 2212. A switch valve 2214 is provided on the side wall of the water storage tank 24. When the water permeable opening 2212 is blocked by the floating buoy 2213, the switch valve 2214 is opened.

[0051] Since the air extraction housing 221 extends below the liquid level of the urine in the water storage tank 24 to ensure the suction force at the air extraction port, during the operation of the fan 222, the urine in the water storage tank 24 will be sucked into the air extraction housing 221. During the use of the fan 222, the power needs to be adjusted according to the actual situation. When the power of the fan 222 continuously increases, the urine in the water storage tank 24 will gradually rise. At the same time, the urine separated in the concave area 21 will also cause the urine volume in the water storage tank 24 to increase, thereby causing the liquid level of the urine in the water storage tank 24 to rise. To prevent the urine from overflowing from the fan 222, a partition is provided inside the air extraction housing 221, so that the partition divides the air extraction housing 221 into an upper cavity and a lower cavity. During the operation of the fan 222, the urine passing through the upper part of the rotating belt 2 falls into the upper cavity and then drains into the lower cavity through the water permeable opening 2212. As the urine in the water storage tank 24 gradually rises, the urine lifts the floating buoy 2213. When the floating buoy 2213 blocks the water permeable opening 2212, the urine in the upper cavity cannot flow into the lower cavity through the water permeable opening 2212, avoiding the situation of urine overflowing from the fan 222 in the water storage tank 24. At the same time, when the water permeable opening 2212 is blocked by the floating buoy 2213, the switch valve 2214 is opened, and the switch valve 2214 discharges the urine in the water storage tank 24. A liquid level sensor for monitoring the lowest liquid level in the water storage tank 24 is provided in the water storage tank 24. When the liquid level in the water storage tank 24 is not monitored by the liquid level sensor, the switch valve 2214 is closed. At this time, the urine in the water storage tank 24 still provides a liquid seal for the bottom of the air extraction housing 221.

[0052] Refer to Figure 6 and Figure 7 : A blowing housing 231 is provided on the inner ring side of the rotating belt 2 corresponding to the unloading area 23. The blowing housing 231 blows air downward onto the rotating belt 2.

[0053] The blowing housing 231 is communicated with the output end of the fan 222. The fan 222 discharges the air in the air extraction housing 221 into the blowing housing 231, and the air is discharged through the blowing housing 231. When the rotating belt 2 passes through the blowing housing 231, the feces remaining on the rotating belt 2 are blown off by the downward flowing air current.

[0054] Refer toFigure 5 , Figure 7 and Figure 9 : A cleaning roller 232 for cleaning the surface of the rotating belt 2 is rotatably provided in the unloading area 23, and the rotation direction of the cleaning roller 232 is opposite to that of the rotating belt 2.

[0055] Two synchronous wheels 233 are provided on the side wall of the processing shell 1. The two synchronous wheels 233 are respectively fixedly connected to the ends of the driving wheel 12 and the end of the cleaning roller 232. A synchronous belt 234 that is in transmission cooperation with the two synchronous wheels 233 is sleeved on the two synchronous wheels 233. Through the transmission of the synchronous wheels 233 and the synchronous belt 234, the rotation direction of the cleaning roller 232 is opposite to that of the rotating belt 2, improving the cleaning effect on the rotating belt 2.

[0056] Working principle: During use, the rotating belt 2 rotates continuously within the processing shell 1. The fecal sewage is input into the processing shell 1 from the feeding port 11. The fecal sewage entering the processing shell 1 is received by the rotating belt 2, and at this time, the fecal sewage is located within the concave area 21. Since the rotating belt 2 has water permeability, the fecal sewage falling into the concave area 21 undergoes preliminary solid-liquid separation, that is, the urine passes through the rotating belt 2 and falls into the water storage tank 24, while the feces are intercepted by the rotating belt 2. As the rotating belt 2 rotates, the feces gradually transfer from the concave area 21 to the horizontal area 22. When the feces pass through the horizontal area 22, the feces located on the horizontal area 22 are spread out, and the urine remaining in the feces undergoes secondary separation in the horizontal area 22. The separated urine falls into the water storage tank 24 for storage. As the rotating belt 2 rotates, the feces passing through the horizontal area 22 adhere to the surface of the rotating belt 2 and move synchronously with the rotating belt 2. The rotating belt 2 drives the feces passing through the horizontal area 22 to the discharging area 23. Since the rotating belt 2 undergoes multiple bends during the rotation from the horizontal area 22 to the discharging area 23, the feces adhering to the rotating belt 2 become loose. When the feces are located in the discharging area 23, the feces adhering to the rotating belt 2 are located below the rotating belt 2, and the feces fall off from the rotating belt 2 under the action of their own gravity. The rotating belt 2 at the discharging area 23 discharges the feces and then rotates towards the concave area 21, repeating the cycle. Compared with centrifugal fecal sewage treatment equipment, through the rotation of the rotating belt 2, the rotating belt 2 can discharge the feces without stopping operation during the separation of fecal sewage, improving the separation efficiency. It should be noted that fecal sewage is composed of urine and feces. The concave area 21 and the horizontal area 22 formed on the upper side of the rotating belt 2 are necessary. If only the concave area 21 is set, a large amount of feces will accumulate at the bottom of the concave area 21, resulting in a reduction in the filtering effect, and the feces output from the concave area 21 will have a high water content. If only the horizontal area 22 is set, the fecal sewage can flow freely after falling into the horizontal area 22. Compared with only setting the concave area 21, the horizontal area 22 has a better filtering effect on fecal sewage, but it is easy for the upper-layer fecal sewage to directly fall into the discharging area 23 along with the rotating belt 2. Therefore, by combining the concave area 21 and the horizontal area 22 and making the feces first input into the concave area 21, it not only avoids the situation where fecal sewage directly drains into the discharging area 23 due to free flow but also ensures the filtering effect on fecal sewage.

[0057] The above embodiments only represent one or several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
