Description

Technical Field

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

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

[0003] Chinese patent announcement No. CN222498928U discloses a livestock manure treatment device, including a treatment box, a feed bin, a water outlet, a discharge port, a filtering mechanism and a crushing mechanism; a filtering cavity and a crushing cavity are provided in the treatment box, and a connecting port is provided between the filtering cavity and the crushing cavity; the feed bin is provided on the inner top wall of the filtering cavity; the water outlet is provided on the side wall of the filtering cavity, and the discharge port is provided 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 scheme realizes the separation of feces and urine through centrifugal force, but under the action of centrifugal force, the separated feces is difficult to be discharged from the center of the filter barrel. If the separated feces needs to be discharged, the filter barrel needs to stop rotating, resulting in that the filter barrel must be stopped when the feces is discharged. 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 that the feces and urine cannot be completely separated. 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 during use, the filtering performance of the filter barrel continues to decline. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention sets a continuously rotating rotating belt in the processing shell, so that the upper rotating belt forms a recessed area and a horizontal area, the lower rotating belt forms a discharge area, and the feeding port is located directly above the recessed area. During processing, the feces and sewage are first put into the recessed area through the feeding port. The recessed area is used to prevent the feces and sewage from flowing freely.

The water filter and the rotating part of the present invention together form a rotating belt, and the water filter receives the feces and sewage, thereby preventing the feces in the feces and sewage from being driven by urine to the joint between the rotating belt and the inner wall of the treatment shell, thereby causing the feces to be discharged into the water storage tank through the joint. A lifting plate is also provided on the water filter. When the lifting plate rotates with the rotating belt and passes through the recessed area, the lifting plate can push away the feces remaining in the recessed area, thereby preventing the feces from accumulating in the recessed area, and also preventing the urine from being unable to pass through the rotating belt smoothly and accumulating on the upper layer of the feces due to the accumulation of feces, thereby preventing the accumulated urine from driving the feces to the joint between the rotating belt and the inner wall of the treatment shell.

[0029] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference Figure 1 , Figure 2 and Figure 4 - Figure 7A self-cleaning livestock manure treatment equipment comprises a treatment shell 1 with a feeding port 11 on the upper part; a water-permeable rotating belt 2 is rotatably arranged in the treatment shell 1, the upper part of the rotating belt 2 is arranged in an undulating structure, and the undulating structure is divided into a recessed area 21 and a horizontal area 22 in the horizontal direction, the feeding port 11 is located directly above the recessed area 21, and the lower part of the rotating belt 2 is a discharge area 23, and a water storage tank 24 for storing urine separated from the recessed area 21 and the horizontal area 22 is horizontally arranged in the inner ring of the rotating belt 2. After the manure is fed from the feeding port 11, it first passes through the recessed area 21 for preliminary solid-liquid separation, and then passes through the horizontal area 22 for secondary solid-liquid separation, and finally the manure attached to the rotating belt 2 is discharged from the discharge area 23.

[0031] There are many structures of existing livestock manure treatment equipment, such as hanging cloth type, centrifugal type, etc. Among them, the hanging cloth type manure treatment equipment is to set the cloth used for filtering vertically and arrange multiple cloths in the horizontal direction, discharge the manure onto the cloth, the feces adhere to the cloth, and the urine is discharged from the bottom of the cloth. However, the hanging cloth type manure treatment equipment cannot be applied to manure containing a large amount of feces. This is because the cloth has a limited interception capacity for feces. When faced with a large amount of feces, the cloth cannot completely intercept the feces, and all the cloths need to be replaced and cleaned regularly. Replacement and cleaning The time is long and the workload is large; the centrifugal feces treatment equipment can overcome the above problems and can be applied to a large amount of feces treatment. During the treatment process, it is not easy for feces to appear in the separated urine, and the separation effect is good. However, due to the effect of centrifugal force, the feces separated from the urine usually remain in the centrifugal feces treatment equipment. When the feces need to be removed, the centrifugal feces treatment equipment needs to stop rotating so that the feces are no longer affected by the centrifugal force, but it causes the feces to be unable to be continuously put into the feces treatment equipment, and there is still a problem of low treatment efficiency. At the same time, the core filtering component of the existing centrifugal feces treatment equipment is mainly the filter screen. The feces 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. Part of the feces will block the mesh of the filter screen. The existing cleaning equipment mostly cleans the filter screen by a cleaning brush, but the cleaning brush cannot clean the feces blocked on the mesh. After long-term use, the mesh of the filter screen will be blocked more and more, which will cause the filtering performance of the filter screen to continue to decline.

[0032] In order to avoid the above situation, the structure of the existing manure treatment equipment is redesigned so that the manure treatment equipment can not only effectively separate the manure containing a large amount of manure, but also automatically discharge the separated manure without stopping the machine, thereby ensuring that the manure can be continuously put into the manure treatment equipment and improving the treatment efficiency. The specific structure and working process of the manure treatment equipment of the present invention are as follows: A plurality of driving wheels 12 are arranged in the processing shell 1. The driving wheels 12 are located on one side of the inner ring of the rotating belt 2 and are used to drive the rotating belt 2 to rotate. A rotation driver 13 for driving the driving wheel 12 to rotate is arranged on one of the driving wheels 12. The rotation driver 13 is preferably a servo motor.

[0033] When in use, the rotating belt 2 is made to rotate continuously in the processing shell 1, and the feces and sewage are fed into the processing shell 1 from the feeding port 11. The feces and sewage entering the processing shell 1 are received by the rotating belt 2, and at this time the feces and sewage are located in the recessed area 21. Since the rotating belt 2 is water permeable, the feces and sewage falling into the recessed area 21 undergo preliminary solid-liquid separation, that is, urine passes through the rotating belt 2 and falls into the water storage tank 24, and the feces are intercepted by the rotating belt 2. As the rotating belt 2 rotates, the feces gradually transfers from the recessed area 21 to the horizontal area 22. When the feces passes through the horizontal area 22, the feces on the horizontal area 22 is 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 urine passes through the horizontal area 22. The feces are attached 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 unloading area 23. Since the rotating belt 2 undergoes multiple bends when rotating from the horizontal area 22 to the unloading area 23, the feces attached to the rotating belt 2 becomes loose. When the feces is located in the unloading area 23, the feces attached to the rotating belt 2 is located below the rotating belt 2. The feces separates from the rotating belt 2 under the action of its own gravity. The rotating belt 2 located at the unloading area 23 discharges the feces and then rotates toward the recessed area 21, repeating the cycle. Compared with the centrifugal feces treatment equipment, the rotating belt 2 can discharge the feces without stopping when separating the feces and sewage through the rotation of the rotating belt 2, thereby improving the separation efficiency. It is worth noting that feces are composed of urine and feces, and 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 reduced filtering effect, and the feces output from the concave area 21 has a high water content. If only the horizontal area 22 is set, the feces 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 feces, but it is easy for the upper layer of feces to fall directly into the unloading area 23 with the rotating belt 2. Therefore, the concave area 21 and the horizontal area 22 are combined, and the feces are first put into the concave area 21, which not only avoids the situation where the feces are directly discharged into the unloading area 23 due to free flow, but also ensures the filtering effect of feces.

[0034] By setting a continuously rotating rotating belt 2 in the processing shell 1, the upper rotating belt 2 forms a recessed area 21 and a horizontal area 22, the lower rotating belt 2 forms a discharge area 23, and the feeding port 11 is located directly above the recessed area 21. During processing, the feces are first put into the recessed area 21 through the feeding port 11. The recessed area 21 is used to prevent the feces from flowing freely. Then the rotating belt 2 drives the feces that have been initially filtered in the recessed area 21 to the horizontal area 22 for secondary filtration, thereby improving the effect of solid-liquid separation. Urine passes through the rotating belt 2 and is collected by the water tank 24. The feces are transported to the discharge area 23 by the rotating belt 2 for discharge, so that the rotating belt 2 can filter the feces and discharge the feces in time at the same time. In summary, the present invention can effectively separate feces containing a large amount of feces, and can automatically discharge the separated feces without stopping the machine, thereby ensuring that the feces can be continuously put into the feces treatment equipment and improving the treatment efficiency.

[0035] Reference Figure 7 The width section of the rotating belt 2 is 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 feces and sewage.

[0036] The water filtering part 25 and the rotating part 26 together constitute the rotating belt 2, and the feces and sewage are received by the water filtering part 25, thereby preventing the feces in the feces and sewage from being driven by urine into the joint between the rotating belt 2 and the inner wall of the processing shell 1, thereby causing the feces to be discharged into the water storage tank 24 through the joint.

[0037] Reference Figure 7 : A plurality of lifting plates 251 for lifting feces in the recessed area 21 are evenly and fixedly arranged on the outer periphery of the rotating belt 2 , and the lifting plates 251 are fixedly arranged on the water filtering part 25 .

[0038] A lifting plate 251 is also provided on the water filtering part 25. When the lifting plate 251 rotates with the rotating belt 2 and passes through the recessed area 21, the lifting plate 251 can push away the feces remaining in the recessed area 21, thereby avoiding the feces accumulation in the recessed area 21, and also avoiding the urine from being unable to pass through the rotating belt 2 smoothly and gathering on the upper layer of the feces due to the accumulation of feces, thereby avoiding the gathered urine from driving the feces to the joint between the rotating belt 2 and the inner wall of the processing shell 1.

[0039] Reference Figure 6 , Figure 7 and Fig. 9 A pressing wheel 212 is rotatably arranged above the rotating 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 rotating belt 2 and rollingly cooperates with the inner ring side of the rotating belt 2. The center height of the pressing wheel 212 is lower than the center height of the supporting wheel 211.

[0040] The support wheel 211 and the pressing wheel 212 are passed through, and the rotating belt 2 is wound around the support wheel 211 and the pressing wheel 212 in sequence, so that the recessed area 21 is formed.

[0041] Reference Figure 7 and Fig. 9 : A lifting 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 lifting frame 213 rises and falls synchronously with the pressing wheel 212.

[0042] The pressing wheel 212 presses the rotating belt 2 by its own gravity, so that the pressing wheel 212 is always in a taut state, thereby preventing the rotating belt 2 from being sunken in the horizontal area 22 due to long-term use.

[0043] Reference Fig. 9 and Fig.10 : An exhaust shell 221 is arranged on the inner ring side of the rotating belt 2 corresponding to the horizontal area 22, and an exhaust port is arranged on the upper part of the exhaust shell 221. The exhaust port is located directly below the rotating belt 2 and contacts with the bottom of the rotating belt 2. A fan 222 for extracting air from the exhaust shell 221 is arranged on the exhaust shell 221.

[0044] When the fan 222 extracts the air in the exhaust shell 221, the air in the upper layer of the horizontal zone 22 passes through the rotating belt 2 from top to bottom in the vertical direction. The flowing air removes the urine in the feces in the horizontal zone 22, thereby improving the solid-liquid separation effect in the horizontal zone 22.

[0045] Reference Figure 1 - Fig.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.

[0046] When the fan 222 is running, the fan 222 sucks the urine in the horizontal area 22 into the suction shell 221, and the suction shell 221 guides the urine into the water storage tank 24, so that the bottom of the suction shell 221 extends into the urine in the water storage tank 24, ensuring that the urine can liquid-seal the bottom of the suction shell 221. When the fan 222 is sucking air through the suction shell 221, air can only be sucked in from the suction port of the suction shell 221, thereby improving the suction force at the suction port.

[0047] Reference Figure 7 and Figure 8A partition plate 2211 is horizontally fixed in the air extraction shell 221, which divides the air extraction shell 221 into an upper cavity and a lower cavity. The liquid level of 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 port 2212 is vertically penetrated through the partition plate 2211. A float 2213 is vertically movable below the water permeable port 2212. When the float 2213 rises, the water permeable port 2212 can be blocked. A switch valve 2214 is provided on the side wall of the water storage tank 24. When the water permeable port 2212 is blocked by the float 2213, the switch valve 2214 is opened.

[0048] In order to ensure the suction force at the suction port, the suction shell 221 extends below the urine level in the water tank 24. During the operation of the fan 222, the urine in the water tank 24 will be sucked into the suction shell 221. During the use of the fan 222, the power needs to be adjusted according to actual conditions. When the power of the fan 222 continues to increase, the urine in the water tank 24 will gradually rise. At the same time, the urine separated by the recessed area 21 will also cause the amount of urine in the water tank 24 to increase, thereby causing the urine level in the water tank 24 to rise. In order to prevent urine from overflowing from the fan 222, a partition is provided in the suction shell 221, so that the partition divides the suction shell 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 When the urine falls into the upper cavity, it is discharged into the lower cavity through the water permeable port 2212. As the urine in the water tank 24 gradually rises, the urine lifts up the float 2213. When the float 2213 blocks the water permeable port 2212, the urine in the upper cavity cannot flow into the lower cavity through the water permeable port 2212, thereby preventing the urine in the water tank 24 from overflowing from the fan 222. At the same time, when the water permeable port 2212 is blocked by the float 2213, the switch valve 2214 is opened, and the switch valve 2214 discharges the urine in the water tank 24. A liquid level sensor for monitoring the lowest liquid level in the water tank 24 is provided in the water tank 24. When the liquid level in the water tank 24 is not monitored by the liquid level sensor, the switch valve 2214 is closed. At this time, the urine in the water tank 24 still seals the bottom of the vacuum shell 221.

[0049] Reference Figure 6 and Figure 7 A blowing shell 231 is provided on one side of the inner ring of the rotating belt 2 corresponding to the unloading area 23, and the blowing shell 231 blows air from top to bottom toward the rotating belt 2.

[0050] The blowing shell 231 is connected to the output end of the fan 222. The fan 222 discharges the air in the exhaust shell 221 into the blowing shell 231, and the air is discharged through the blowing shell 231. When the rotating belt 2 passes through the blowing shell 231, the feces remaining on the rotating belt 2 is blown down by the airflow flowing from top to bottom.

[0051] Reference Figure 5 , Figure 7 and Fig. 9 : A cleaning roller 232 is rotatably arranged in the unloading area 23 to clean the surface of the rotating belt 2, and the rotation direction of the cleaning roller 232 is opposite to the rotation direction of the rotating belt 2.

[0052] Two synchronous wheels 233 are arranged on the side wall of the processing shell 1, and the two synchronous wheels 233 are fixedly connected to the end of the driving wheel 12 and the end of the cleaning roller 232 respectively. A synchronous belt 234 is sleeved on the two synchronous wheels 233 and is matched with the two synchronous wheels 233 for transmission. Through the transmission of the synchronous wheels 233 and the synchronous belt 234, the rotation direction of the cleaning roller 232 is opposite to the rotation direction of the rotating belt 2, thereby improving the cleaning effect of the rotating belt 2.

[0053] Working principle: When in use, the rotating belt 2 is made to rotate continuously in the processing shell 1, and the feces and sewage are fed into the processing shell 1 from the feeding port 11. The feces and sewage entering the processing shell 1 are received by the rotating belt 2, and at this time the feces and sewage are located in the recessed area 21. Since the rotating belt 2 is water permeable, the feces and sewage falling into the recessed area 21 undergo preliminary solid-liquid separation, that is, urine passes through the rotating belt 2 and falls into the water storage tank 24, and the feces are intercepted by the rotating belt 2. As the rotating belt 2 rotates, the feces gradually transfers from the recessed area 21 to the horizontal area 22. When the feces passes through the horizontal area 22, the feces on the horizontal area 22 is 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 urine passes through the horizontal area 22. The feces after the horizontal zone 22 adheres to the surface of the rotating belt 2 and moves synchronously with the rotating belt 2. The rotating belt 2 drives the feces passing through the horizontal zone 22 to the unloading zone 23. Since the rotating belt 2 undergoes multiple bends during the rotation from the horizontal zone 22 to the unloading zone 23, the feces attached to the rotating belt 2 becomes loose. When the feces is located in the unloading zone 23, the feces attached to the rotating belt 2 is located below the rotating belt 2. The feces separates from the rotating belt 2 under the action of its own gravity. The rotating belt 2 located at the unloading zone 23 discharges the feces and then rotates toward the recessed zone 21, repeating a cycle. Compared with the centrifugal feces treatment equipment, the rotating belt 2 rotates, so that the rotating belt 2 can discharge the feces without stopping when separating the feces and sewage, thereby improving the separation efficiency. It is worth noting that feces are composed of urine and feces, and 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 reduced filtering effect, and the feces output from the concave area 21 has a high water content. If only the horizontal area 22 is set, the feces 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 feces, but it is easy for the upper layer of feces to fall directly into the unloading area 23 with the rotating belt 2. Therefore, the concave area 21 and the horizontal area 22 are combined, and the feces are first put into the concave area 21, which not only avoids the situation where the feces are directly discharged into the unloading area 23 due to free flow, but also ensures the filtering effect of feces.

[0054] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
