Description

Technical Field

[0001] The invention relates to the field of excrement treatment, and in particular to a solid-liquid separation device having a biogas treatment structure in an aquaculture excrement storage tank. Background Art

[0002] The solid-liquid separation of feces is an important part of the feces treatment process, which is helpful for the subsequent further treatment and resource utilization of feces. For the liquid part: if anaerobic fermentation is to be carried out to produce biogas, the fermentation efficiency of the liquid part after the solid impurities are separated is higher, because the solid impurities may affect the fermentation process of microorganisms. At the same time, if the liquid is to be deeply treated to meet the emission standards, reducing the suspended solids will help improve the treatment effect. For the solid part: the solid part can be more conveniently composted or made into organic fertilizer, because after the moisture content is reduced, the composting process will not produce an anaerobic environment or emit unpleasant odors due to excessive moisture.

[0003] In the process of solid-liquid separation of feces, the conventional method uses physical pressure to achieve filtering and separation of feces. However, since feces have a certain viscosity, when squeezing and separating feces with lower viscosity, the separation is not complete, which can easily lead to a higher liquid content inside the solid feces, and thus the separated solid feces cannot be collected for subsequent utilization.

[0017] Compared with the prior art, the present invention has the following beneficial effects: In the scheme of the present invention: 1. When drying feces, the first reduction motor is driven, and the first reduction motor drives the support rod and the support plate to rotate, thereby driving the second gas pipe and the movable shaft to rotate. During the rotation of the movable shaft, the slide bar abutting on the surface thereof slides along the limit groove. In addition, the limit groove provided on the movable shaft is corrugated, thereby causing the slide bar on the limit groove to reciprocate up and down. The reciprocating movement of the slide bar drives the connecting ring and the connecting rod to reciprocate, thereby driving the pressing plate to move up and down. When the pressing plate moves up and down, it drives the slide plate and the sealing plate to slide, thereby respectively realizing the connection state of the first gas pipe and the feed pipe, realizing the release of biogas and feces, thereby realizing the heating and drying of the feces to accelerate the effect of solid-liquid separation; 2.

When the sealing plate slides upward, the exhaust hole is closed. At this time, the slide plate and the feed pipe are in an open and closed state, and the feces are released. In addition, in some cases, the partition is a heating plate. When the exhaust hole is closed, the igniter inside the partition is turned on to burn the biogas inside the partition.

The outer shell fixedly connected to the partition away from the first gas transmission pipe surface is used for sealing and squeezing feces to achieve solid-liquid separation. The support frame fixedly connected to the upper surface of the outer shell is used to support the pulley. The pulley shell rotatably connected between the support frames realizes the rotation of the filter plate by rotation. The filter plate will tilt downward from the center during the rotation. During the tilting process, the feces accumulated on its surface slides downward to enter directly above the material plate. The steel cable wrapped on the outer surface of the pulley is used to connect the filter plate and the pressing plate to achieve the opposite and reverse movement of the filter plate and the pressing plate. When the pressing plate moves downward, the steel cable cooperates with the pulley to pull the filter plate upward. Similarly, the pressing plate moves up and the filter plate rotates downward, thereby realizing the connection and separation of the filter plate and the connecting plate. 4. The air holes arranged near the upper end of the outer surface of the second gas pipe are used to collect the biogas inside the static tank. The support rod fixedly connected to the upper end of the second gas pipe is used to connect the second gas pipe support plate, so as to realize the rotation of the second gas pipe and the movable shaft. In addition, the spiral rods in the circular array on the lower surface of the support plate can stir the feces. During the stirring process of the feces, the biogas inside the feces gathers upward, and the gathered biogas can enter the second gas pipe along the air holes. When collecting biogas, the first reduction motor can be turned on, and the first reduction motor drives the support plate to rotate. The rotation of the support plate drives the spiral rod to rotate and then stirs the feces inside the mixing tank and the static tank. During the stirring process of the feces, the biogas at the bottom gathers upward near the air holes, and then enters the second gas pipe along the air holes, passes through the movable shaft, and enters the first gas pipe to release and utilize the biogas.

[0022] In order to solve this technical problem, the present invention provides a solid-liquid separation device with a biogas treatment structure in a livestock manure storage tank, which is used to reduce the waste liquid content inside the solid manure.

[0023] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0024] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0025] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0026] A solid-liquid separation device with a biogas treatment structure for a livestock manure storage tank comprises a movable shaft 101, a limiting groove 102 is arranged on the outer surface of the movable shaft 101, a sliding rod 103 is slidably connected to the inner wall of the limiting groove 102, a connecting ring 104 is fixedly connected to the end of the sliding groove away from the sliding rod 103, a connecting rod 105 is fixedly connected to the outer surface of the connecting ring 104, a pressing plate 106 is fixedly connected to the other end of the connecting rod 105, an L-shaped rod 107 is fixedly connected to the lower surface of the pressing plate 106, a slide plate 108 is fixedly connected to the horizontal end of the L-shaped rod 107, an arc rod 109 is penetrated and connected to the side of the slide plate 108, a connecting shaft 110 is fixedly connected to the upper end of the arc rod 109, and a sealing plate 111 is fixedly connected to the other end of the connecting shaft 110.

[0027] When drying feces, the first reduction motor 604 is driven, and the first reduction motor 604 drives the support rod 601 and the support plate to rotate, thereby driving the second gas pipe 501 and the movable shaft 101 to rotate. During the rotation of the movable shaft 101, the sliding rod 103 abutting on the surface thereof slides along the limiting groove 102. In addition, the limiting groove 102 provided on the movable shaft 101 is corrugated, thereby causing the sliding rod 103 on the limiting groove 102 to reciprocate up and down. The reciprocating movement of the sliding rod 103 drives the connecting ring 104 and the connecting rod 105 to reciprocate, thereby driving the pressing plate 106 to move up and down. When the pressing plate 106 moves up and down, it drives the sliding plate 108 and the sealing plate 111 to slide, thereby respectively realizing the connection state of the first gas pipe 202 and the feed pipe 204, realizing the release of biogas and feces, thereby realizing the heating and drying of the feces to accelerate the solid-liquid separation effect.

[0028] The sealing plate 111 is slidably connected to the inner wall of the groove 201, and the groove 201 is arranged on the outer surface of the first gas pipe 202. The lower surface of the slide plate 108 is slidably connected to the plug plate 203, and the plug plate 203 is connected to the feed pipe 204 away from the first gas pipe 202. The plug plate 203 penetrates and connects to the first gas pipe 202. There are a number of partitions 205 in a circular array on the outer surface of the first gas pipe 202. The partition 205 abuts against the pressure plate 106. The pressure plate 106 is arc-shaped and forms a closed loop with the partition 205.

[0029] The sealing plate 111 is slidably connected to the inner wall of the groove 201 to release and lock the biogas. When the sealing plate 111 slides downward, an exhaust port is formed between the sealing plate 111 and the plug plate 203. At this time, the biogas inside the first gas pipe 202 enters the partition 205. At this time, the slide plate 108 and the feed pipe 204 are in a sealed state. When the sealing plate 111 slides upward, the exhaust hole is closed. At this time, the slide plate 108 and the feed pipe 204 are in an open and closed state, and the feces are released. In addition, in some cases, the partition 205 is a heating plate. When the exhaust hole is closed, the igniter inside the partition 205 is turned on to burn the biogas inside the partition 205. The biogas heats the partition 205 during the combustion process, and then heats and dries the feces between the partitions 205.

[0030] A plurality of connecting plates 301 are fixedly connected between the partitions 205 . The connecting plates 301 are fixedly connected to form grooves 302 . Through holes 303 are provided on the sides of the connecting plates 301 .

[0031] The connecting plate 301 fixedly connected between the partitions 205 is used to separate feces. The grooves 302 formed by the fixed connection between the connecting plates 301 can divide the feces into independent units to achieve block drying for collection. The through holes 303 set on the side of the connecting plate 301 can make each independent unit evenly covered with feces. When the feces are released and separated, the feces are discharged into the partition 205 along the discharge port formed by the slide plate 108 and the feed pipe 204, and then the feces are evenly distributed to each independent unit along the through holes 303 set on the connecting plate 301 to achieve the drying operation.

[0032] The partition 205 is fixedly connected to the outer shell 401 on the surface away from the first air pipe 202, and the upper surface of the outer shell 401 is fixedly connected to the support frame 402. A pulley 403 is rotatably connected between the support frames 402. A steel cable 404 is wound around the outer surface of the pulley 403. One end of the steel cable 404 is fixedly connected to the pressure plate 106, and the other end is fixedly connected to a filter plate 405. The filter plates 405 have multiple pieces and are arc-shaped. The filter plates 405 are fixedly connected to a rotating shaft 406 away from the steel cable 404. The rotating shaft 406 is hinged on the outer surface of the first air pipe 202.

[0033] The outer shell 401 to which the partition 205 is fixedly connected away from the first air pipe 202 is used for sealing and squeezing feces to achieve solid-liquid separation. The support frame 402 fixedly connected to the upper surface of the outer shell 401 is used to support the pulley 403. The pulley 403 shell rotatably connected between the support frame 402 realizes the rotation of the filter plate 405 by rotation. The filter plate 405 will tilt downward from the center during the rotation. During the tilting process, the feces accumulated on its surface slides downward and enters directly above the material plate 701. The steel cable 404 wrapped around the outer surface of the pulley 403 is used to connect the filter plate 405 and the pressing plate 106 to achieve the toward and reverse movement of the filter plate 405 and the pressing plate 106. When the pressing plate 106 moves downward, the steel cable 404 cooperates with the pulley 403 to pull the filter plate 405 to rotate upward. Similarly, the pressing plate 106 moves up and the filter plate 405 rotates downward, thereby realizing the connection and separation of the filter plate 405 and the connecting plate 301.

[0034] The lower end of the movable shaft 101 is connected to the first air pipe 202 and is rotatably connected. The upper end of the movable shaft 101 is fixedly connected to the second air pipe 501. The upper end of the second air pipe 501 is connected to the static tank 502.

[0035] The lower end of the movable shaft 101 is connected to the first air pipe 202 and the rotational connection can prevent the movable shaft 101 from driving the first air pipe 202 to rotate during the rotation process, thereby preventing the sealing plate 111 from rotating, resulting in the sealing plate 111 being unable to slide to release the biogas. The static tank 502 connected to the upper end of the second air pipe 501 is used to statically store feces to collect biogas. The feed pipe 204 is connected to the static tank 502 and the feed pipe 204 is lower than the height of the second air pipe 501 in the static tank 502 to prevent feces from entering the second air pipe 501.

[0037] The air holes arranged near the upper end of the outer surface of the second gas pipe 501 are used to collect the biogas inside the static tank 502. The support rod 601 fixedly connected to the upper end of the second gas pipe 501 is used to connect the support plate 602 of the second gas pipe 501, so as to realize the rotation of the second gas pipe 501 and the movable shaft 101. In addition, the spiral rods 603 in the annular array on the lower surface of the support plate 602 can stir the feces. During the stirring process of the feces, the biogas inside the feces gathers upwards, and the gathered biogas can enter the second gas pipe along the air holes. Inside the tube 501, when collecting biogas, the first reduction motor 604 can be turned on, and the first reduction motor 604 drives the support plate 602 to rotate. The rotation of the support plate 602 drives the screw rod 603 to rotate, and then stirs the feces inside the mixing tank 503 and the static tank 502. During the stirring process of the feces, the biogas at the bottom gathers upward near the pores, and then enters the second gas pipe 501 along the pores, passes through the movable shaft 101, and enters the first gas pipe 202 for release and utilization of the biogas.

On the other hand, the guide groove 803 arranged on its outer surface can guide the waste liquid after solid-liquid separation to realize the collection of the waste liquid. When collecting, the waste liquid flows through the guide groove 803 and the guide plate 804 to the drainage bin 807, and enters the water storage bin 808 through the drainage bin 807 to realize the collection of the waste liquid. The second reduction motor 802 fixedly connected inside the motor housing 801 drives the material plate 701 to rotate. During the rotation of the material plate 701, the feces accumulated on the surface of the material plate 701 enters the waste box 1003 along the opening 1001 through the collecting pipe 1002 to realize the collection of the feces.

The reciprocating movement of the slide bar 103 drives the connecting ring 104 and the connecting rod 105 to reciprocate, thereby driving the pressing plate 106 to move up and down. When the pressing plate 106 moves up and down, it drives the slide plate 108 and the sealing plate 111 to slide, thereby respectively realizing the connection state of the first gas pipe 202 and the feed pipe 204, realizing the release of biogas and feces, thereby realizing the heating and drying of the feces to accelerate the solid-liquid separation effect. The sealing plate 111 is slidably connected to the inner wall of the slot 1 201 to realize the release and locking of the biogas. When the sealing plate 111 slides downward, an exhaust port is formed between the sealing plate 111 and the plug plate 203. At this time, the biogas inside the first gas pipe 202 enters the inside of the partition 205. At this time, the slide plate 108 and the feed pipe 204 are in a sealed state. When the sealing plate 111 slides upward, the exhaust hole is closed. At this time, the slide plate 108 and the feed pipe 204 are in an open and closed state, and the feces are released. In addition, in some cases, the partition 205 is a heating plate. When the exhaust hole is closed, the igniter inside the partition 205 is turned on to burn the biogas inside the partition 205. The biogas heats the partition 205 during the combustion process, and then the feces between the partitions 205 are heated and dried; The outer shell 401 fixedly connected to the partition 205 away from the first air pipe 202 is used for sealing and squeezing feces to achieve solid-liquid separation. The support frame 402 fixedly connected to the upper surface of the outer shell 401 is used to support the pulley 403. The pulley 403 shell rotatably connected between the support frame 402 realizes the rotation of the filter plate 405 by rotation. The filter plate 405 will tilt downward from the center during the rotation. During the tilting process, the feces accumulated on its surface slides downward and enters directly above the material plate 701. The steel cable 404 wound on the outer surface of the pulley 403 is used to connect the filter plate 405 and the pressing plate 106 to achieve the relative movement and reverse movement of the filter plate 405 and the pressing plate 106. When the pressing plate 106 moves downward, the steel cable 404 cooperates with the pulley 403 to pull the filter plate 405 to rotate upward. Similarly, the pressing plate 106 moves up and the filter plate 405 rotates downward, thereby realizing the connection and separation of the filter plate 405 and the connecting plate 301. The air holes arranged near the upper end of the outer surface of the second gas pipe 501 are used to collect the biogas inside the static tank 502. The support rod 601 fixedly connected to the upper end of the second gas pipe 501 is used to connect the support plate 602 of the second gas pipe 501, so as to realize the rotation of the second gas pipe 501 and the movable shaft 101. In addition, the spiral rods 603 in the annular array on the lower surface of the support plate 602 can stir the feces. During the stirring process of the feces, the biogas inside the feces gathers upwards, and the gathered biogas can enter the second gas pipe along the air holes. Inside the tube 501, when collecting biogas, the first reduction motor 604 can be turned on, and the first reduction motor 604 drives the support plate 602 to rotate. The rotation of the support plate 602 drives the screw rod 603 to rotate, and then stirs the feces inside the mixing tank 503 and the static tank 502. During the stirring process of the feces, the biogas at the bottom gathers upward near the pores, and then enters the second gas pipe 501 along the pores, passes through the movable shaft 101, and enters the first gas pipe 202 for release and utilization of the biogas.
