Description

Technical Field

[0001] The present invention belongs to the technical field of livestock and poultry manure treatment, and specifically relates to an efficient livestock and poultry manure treatment system for farms. Background Art

[0002] In modern livestock and poultry farming, with the continuous expansion of the breeding scale and the improvement of the intensification level, the problem of livestock and poultry manure treatment has become increasingly prominent. Livestock and poultry manure not only contains a large amount of organic matter, nitrogen, phosphorus and other nutrient elements, but also contains harmful substances such as pathogens and heavy metals. If not properly treated and directly discharged into the environment, it will cause serious pollution to soil, water sources and air, affecting the ecological balance and human health.

[0003] At present, there are various treatment methods for livestock and poultry manure in farms, but there are generally problems such as low treatment efficiency, poor treatment effect and serious environmental pollution. The main livestock and poultry manure treatment technologies in farms include composting fermentation, anaerobic digestion, aerobic treatment and other methods. These technologies have realized the resource utilization and reduction treatment of manure to a certain extent, but there are still many limitations.

[0004] Existing separation devices are often unreasonably designed and have low separation efficiency, resulting in high impurity content in the separated solid and liquid parts, affecting the subsequent composting or anaerobic digestion effect; the liquid part contains too many solid impurities, increasing the treatment difficulty and cost.

[0005] In view of the limitations of existing livestock and poultry manure treatment technologies, there is an urgent need for a new type of livestock and poultry manure treatment system that can achieve efficient separation of solid-liquid manure for subsequent targeted treatment. Summary of the Invention

[0006] In order to solve the above problems, the purpose of the present invention is to provide an efficient livestock and poultry manure treatment system for farms, which can achieve efficient separation of solid-liquid manure, lay a good foundation for subsequent targeted treatment, and thus improve the manure treatment efficiency.

[0007] In order to achieve the above purpose, the technical solution of the present invention is as follows:

[0008] An efficient livestock and poultry manure treatment system for farms, including a preliminary separation module, a solid-liquid separation module, a biological treatment module and a solid manure treatment module;

[0009] The preliminary separation module is used to remove large particle impurities and gravel in the collected livestock and poultry manure;

[0010] The solid-liquid separation module includes a first separation carrier and a second separation carrier; a separation channel is provided in the first separation carrier, and a first separation pipe is connected to the separation channel, and the first separation pipe is used to transport the livestock and poultry manure in the separation channel to the biological treatment module; a solid separation component is provided in the separation channel, and the solid separation component is used to separate the solids in the livestock and poultry manure based on the backflow generated by the flow of the livestock and poultry manure; the second separation carrier is located below the first separation carrier, and a dehydration component is provided in the second separation carrier, and the dehydration component is used to receive the solids separated by the solid separation component and perform dehydration treatment;

[0011] The biological treatment module is used to receive the separated liquid manure and perform biochemical treatment;

[0012] The solid manure treatment module is used to deeply treat the separated solid manure.

[0013] Adopting the above scheme has the following beneficial effects:

[0014] 1. In this scheme, after removing large-particle impurities and sand and gravel through the preliminary separation module, the solid-liquid separation module uses the solid separation component in the first separation carrier to effectively separate the solid manure from the mixed manure based on the backflow effect generated by the flow of the livestock and poultry manure. This step not only improves the separation efficiency but also reduces the difficulty and cost of subsequent treatment. Subsequently, the dehydration component in the second separation carrier further dehydrates the solid manure, removing the excess liquid components therein, making the separation of solid and liquid manure more thorough.

[0015] 2. In this scheme, the liquid manure and solid manure treated by the solid-liquid separation module have clearer properties, providing more favorable conditions for subsequent biological treatment and solid manure treatment. The liquid manure can directly enter the biological treatment module for biochemical treatment to remove harmful substances and improve water quality; while the solid manure enters the solid manure treatment module for in-depth treatment, such as composting and fermentation, and is converted into organic fertilizer or biomass energy.

[0016] 3. The entire processing system of this scheme has a clear process, and each module works together, significantly improving the processing efficiency of livestock and poultry manure. At the same time, due to the thorough solid-liquid separation, the energy consumption and material consumption in the subsequent treatment process are reduced, and the treatment cost is lowered.

[0017] Furthermore, the solid separation component includes a number of backflow chambers, which are arranged along the length direction of the separation channel. The backflow chambers are used to divide the livestock and poultry manure in the separation channel into a main flow and a branch flow. When the branch flow meets the main flow, the flow direction of the branch flow is opposite to that of the main flow.

[0018] Beneficial effects: The design of the reflux chamber enables the livestock and poultry manure to form a complex flow pattern in the separation channel. When the tributary meets the mainstream and generates a flow in the opposite direction, this countercurrent effect helps to more effectively separate the solid particles from the mixed liquid. Under the action of the countercurrent, the solid particles are more easily captured and deposited in the reflux chamber, thus improving the efficiency of solid-liquid separation.

[0019] The structure composed of the reflux chamber and the separation channel is similar to the Tesla valve structure. By utilizing the resistance generated during the reverse flow of the Tesla valve, the livestock and poultry manure undergoes turbulence and generates a reflux when passing through the reflux chamber, thereby accelerating the deposition of solids in the livestock and poultry manure in the reflux chamber until the reflux chamber is filled with solids. Then, the manure flow in the separation channel returns to normal and enters the next reflux chamber, repeating the above process. This continuous process ensures the persistence and high efficiency of solid-liquid separation.

[0020] Furthermore, the separation channel is inclined.

[0021] Beneficial effects: The inclined separation channel makes it easier for the livestock and poultry manure to form a gravity flow during the flow process, which helps the solid particles to deposit faster to the bottom of the channel or in the reflux chamber under the action of gravity, thus improving the efficiency of solid-liquid separation.

[0022] Furthermore, the reflux chamber is opened at the bottom of the separation channel.

[0023] Beneficial effects: Since the reflux chamber is located at the bottom, the deposited solid particles are not easily resuspended by the water flow disturbance. This helps to maintain the cleanliness of the separated liquid manure and reduces the difficulty of subsequent treatment.

[0024] Furthermore, the dehydration component includes a driving member and a screw; a dehydration channel is provided in the second separation carrier, the dehydration channel is inclined, the screw is rotationally matched with the dehydration channel, and the driving member is used to drive the screw to rotate; discharge channels are connected between the dehydration channel and each reflux chamber, and opening and closing components are provided in each reflux chamber. The opening and closing components are used to realize the on-off between the reflux chamber and the discharge channel and the on-off between the reflux chamber and the separation channel; a squeezing component and an opening are provided at one end of the dehydration channel away from the driving member, the opening is located at the higher end of the dehydration channel, and the squeezing component is used to generate resistance to block the manure in the dehydration channel from passing through the opening; a second separation pipe is connected to the other end of the dehydration channel away from the opening, and the second separation pipe is used to collect the liquid in the dehydration pipe.

[0025] Beneficial effects: When the solid feces in the reflux chamber are filled up, by starting the opening and closing assembly, the partition between the reflux chamber and the separation channel is cut off, and at the same time, the reflux chamber is communicated with the dehydration channel. The solid feces in the reflux chamber slide down into the dehydration channel under the action of their own gravity. By starting the driving member, the screw rotates. The rotation of the screw conveys the solids in the dehydration channel along the dehydration channel to the opening respectively. Under the synergistic action of the screw and the extrusion assembly, sufficient resistance can be generated to extrude the solid feces, so as to effectively remove the moisture therein. The dehydrated solid feces, under the continuous conveyance of the screw, push open the extrusion assembly and are discharged through the opening.

[0026] Further, the extrusion assembly includes a blocking member; the blocking member is slidably matched with the dehydration channel, and a compression spring is arranged between the blocking member and the inner wall of the dehydration channel.

[0027] Beneficial effects: The extrusion force generated by the compression spring on the blocking member enables the solid feces to overcome greater resistance to pass through the opening during the conveying process of the screw. This design increases the residence time and compression degree of the solid feces in the dehydration channel, thereby improving the dehydration effect. Under the push of the screw, the solid feces are gradually compressed and the moisture is squeezed out. The presence of the compression spring ensures the continuity and stability of the dehydration process, and avoids incomplete dehydration caused by insufficient pressure.

[0028] Due to the extrusion force of the compression spring, the solid feces cannot easily push open the blocking member when they do not reach a sufficient degree of dehydration. This effectively prevents the premature discharge of the insufficiently dehydrated solid feces.

[0029] Further, the opening and closing assembly includes a cylinder and an opening and closing member; one side of the reflux chamber is communicated with an opening and closing groove, the opening and closing member is slidably matched with the opening and closing groove, and the cylinder is used to drive the opening and closing member to move; a plurality of flow velocity sensors are also arranged in the separation channel, and the flow velocity sensors are used to detect the fluid flow velocity before flowing through each reflux chamber respectively; the flow velocity sensors are electrically connected to a control unit, and the control unit is used to judge the filling condition of each reflux chamber based on the information of each flow velocity sensor and control the operation of the cylinder.

[0030] Beneficial effects: When the reflux chamber is filled up, the reflux chamber will no longer generate reflux and resistance (for the fluid in this section of the distance before the reflux chamber). At this time, the fluid flow velocity in this section of the distance will increase. When the flow velocity reaches the preset flow velocity, the control unit judges that the reflux chamber is filled up, and starts the cylinder to operate, so as to close the reflux chamber and make the solid feces in the reflux chamber slide down into the dehydration channel for dehydration treatment.

[0031] The fluid flow rate before each reflux chamber is monitored in real time by a flow rate sensor, and the control unit can accurately judge the filling state of each reflux chamber based on the flow rate data. When the reflux chamber is filled, the fluid flow rate in this section will increase. When the preset flow rate is reached, the control unit can judge that the reflux chamber is full. Based on the information of the flow rate sensor, the control unit can automatically start the cylinder to close the reflux chamber and make the solid feces slide down. This automatic control reduces manual intervention and improves the processing efficiency and accuracy.

[0032] When the reflux chamber is filled and closed, the solid feces in it will slide into the dehydration channel for dehydration treatment. This design ensures that the solid feces are dehydrated when they reach a sufficient concentration and volume, improving the dehydration efficiency and effect.

[0033] Furthermore, a pretreatment mechanism is also provided between the diversion channel and the first separation pipe; the pretreatment mechanism includes an extrusion chamber; piston plates are symmetrically arranged in the extrusion chamber, and extrusion springs are arranged between the piston plates and the extrusion chamber. The piston plates are all slidably matched with the extrusion chamber; a piston block is slidably matched in the middle of the extrusion chamber. An upper return channel and a lower return channel are arranged in the piston block. The upper return channel and the lower return channel are arranged in central symmetry. The upper return channel and the lower return channel are respectively communicated with both ends of the extrusion chamber. Activated carbon filter plates are arranged between the piston block and the piston plates, and the activated carbon filter plates are fixedly connected to the piston block; annular pipes, a first outlet and a second outlet are also communicated on both sides of the extrusion chamber; the annular pipe is used to alternately communicate the separation channel with the upper return channel and the lower return channel; the first outlet and the second outlet are used to alternately communicate with the extrusion chamber based on the movement of the piston block; both the first outlet and the second outlet are communicated with the first separation pipe.

[0034] Beneficial effects: The livestock and poultry manure (liquid) after being treated by the solid separation component is input into the extrusion chamber through the annular pipe. When the annular pipe is communicated with the upper return channel, the livestock and poultry manure gradually accumulates at one end of the extrusion chamber, so that the piston block moves towards the other end of the extrusion chamber. When the annular pipe is communicated with the lower return channel, the livestock and poultry manure gradually accumulates at the other end of the extrusion chamber, so that the piston block moves in the reverse direction, so that the piston block moves back and forth continuously. The livestock and poultry manure in the extrusion chamber is discharged through the first outlet and the second outlet. When the livestock and poultry manure enters the extrusion chamber, the livestock and poultry manure will repeatedly pass through the activated carbon filter plate under the action of pressure, and harmful substances such as heavy metals in the livestock and poultry manure are removed through the activated carbon filter plate.

[0035] Through the reciprocating movement of the piston block in the extrusion chamber, the livestock and poultry manure is repeatedly guided through the activated carbon filter plate. This dynamic filtration process not only improves the filtration efficiency, but also can more effectively remove heavy metals and other harmful substances in the manure. Compared with static filtration, dynamic filtration can make better use of the adsorption capacity of activated carbon to ensure higher quality of the treated manure.

[0036] This pretreatment mechanism uses the self-pressure of livestock and poultry manure to drive the movement of the piston block, eliminating the need for an additional power source, achieving automated processing, and reducing energy consumption. At the same time, by alternately connecting the upper and lower loop channels, a continuous and stable processing flow is realized.

[0037] The reciprocating movement of the piston block accelerates the flow and filtration process of livestock and poultry manure in the extrusion chamber, thereby improving the overall processing efficiency.

[0038] Furthermore, the first separation pipe and the second separation pipe form a tee pipe structure; a pump assembly and a pair of valves are provided on the tee pipe. The valves are used to respectively control the on-off of the first separation pipe and the second separation pipe, and the pump assembly is used to pump the livestock and poultry manure in the first separation pipe and the second separation pipe into the biological treatment module.

[0039] Beneficial effects: Through the pump assembly, the system can efficiently pump the liquid livestock and poultry manure in the first separation pipe and the second separation pipe into the biological treatment module. This centralized processing method significantly improves the processing efficiency and reduces the processing time and cost.

[0040] Furthermore, the opening and closing member includes a left side plate and a right side plate; a connecting rod is provided between the left side plate and the right side plate, and a shielding plate is provided on the right side plate; the left side plate is slidably engaged with the discharge channel, the right side plate is slidably engaged with the return chamber, the shielding plate is slidably engaged with the opening and closing groove, and the right side plate is fixedly connected to the output shaft of the cylinder.

[0041] Beneficial effects: When it is necessary to push the solid manure in the return chamber into the discharge channel, the right side plate is moved by the cylinder, which in turn drives the left side plate to move. At the same time, the shielding plate moves synchronously with the right side plate, separating the separation channel from the return chamber while transferring the solid manure from the return chamber to the discharge channel.

[0054] The following is a further detailed description through specific embodiments:

[0055] Embodiment 1 is basically as shown in the appendix Figures 1 - 8 shown: A high-efficiency livestock and poultry manure treatment system for a farm mainly includes a preliminary separation module, a solid-liquid separation module, a biological treatment module, and a solid manure treatment module. Livestock and poultry manure refers to the general term for liquid manure and solid manure generated by livestock and poultry farms. Liquid manure refers to the liquid waste generated by livestock and poultry farms, which includes the general term for livestock and poultry urine, residual feces, and wastewater generated during the production process. Solid manure refers to the solid waste generated by livestock and poultry farms, which includes feces and feed residues, etc. When treating livestock and poultry manure, the livestock and poultry manure is first collected in a designated collection pool.

[0056] The preliminary separation module is used to remove large particle impurities and sand and gravel in the collected livestock and poultry manure; the preliminary separation module corresponds to the pretreatment project of livestock and poultry manure, mainly including a grille and a grit chamber. The large particle impurities and sand and gravel are removed through physical methods such as a sieve or grille and a grit chamber to prevent these impurities from damaging the subsequent treatment equipment. The livestock and poultry manure after preliminary separation is transported to the solid-liquid separation module through a pump or pipeline.

[0057] The solid-liquid separation module includes a first separation carrier 1 and a second separation carrier 2; a separation channel 101 is provided in the first separation carrier 1. Preferably, as shown in the appendix Figure 3 shown, the separation channel 101 is inclined. The separation channel 101 is communicated with a first separation pipe 3, and the first separation pipe 3 is used to transport the livestock and poultry manure in the separation channel 101 to the biological treatment module.

[0058] A solid separation component is arranged in the separation channel 101, and the solid separation component is used to separate the solids in the livestock and poultry manure based on the backflow generated by the flow of the livestock and poultry manure; specifically, the solid separation component includes a plurality of backflow chambers 102, and the backflow chambers 102 are arranged along the length direction of the separation channel 101. The backflow chambers 102 are used to divide the livestock and poultry manure in the separation channel 101 into a main flow and a branch flow. When the branch flow meets the main flow, the flow direction of the branch flow is opposite to that of the main flow. Preferably, in this embodiment, the backflow chambers 102 are opened at the bottom of the separation channel 101. In some other embodiments, the backflow chambers 102 can be opened on the side wall of the separation channel 101.

[0059] The second separation carrier 2 is located below the first separation carrier 1. A dehydration assembly is provided inside the second separation carrier 2. The dehydration assembly is used to receive the solids separated by the solid separation assembly and perform dehydration treatment. Specifically, in combination with the attached Figure 4 and the attached Figure 6 As shown, the dehydration assembly includes a driving member 201 and a screw 204. A dehydration channel 203 is formed inside the second separation carrier 2. The dehydration channel 203 is inclined. The screw 204 is rotationally matched with the dehydration channel 203. The driving member 201 is used to drive the screw 204 to rotate. The driving member 201 adopts a servo motor. The servo motor is installed at the bottom of the second separation carrier 2 through bolts. The output shaft of the servo motor is axially fixed to the screw 204 through a coupling. In combination with the attached Figure 7 As shown, a discharge channel 202 is communicated between the dehydration channel 203 and each reflux chamber 102. An opening and closing assembly is provided inside each reflux chamber 102. The opening and closing assembly is used to realize the on-off between the reflux chamber 102 and the discharge channel 202 and the on-off between the reflux chamber 102 and the separation channel 101.

[0060] Specifically, the opening and closing assembly includes a cylinder 116 and an opening and closing member 114. One side of the reflux chamber 102 is communicated with an opening and closing groove 115. The opening and closing member 114 is slidably matched with the opening and closing groove 115. The cylinder 116 is used to drive the opening and closing member 114 to move. In combination with the attached Figure 3 As shown, a plurality of flow velocity sensors 103 are further installed inside the separation channel 101. The flow velocity sensors 103 are used to respectively detect the flow velocity of the fluid (livestock and poultry manure, the same below) before flowing through each reflux chamber 102. The flow velocity sensors 103 are electrically connected to a control unit. The control unit is used to judge the filling condition inside each reflux chamber 102 based on the information of each flow velocity sensor 103 and control the operation of the cylinder 116. Specifically, in combination with the attached Figure 7 and the attached Figure 8 As shown, the opening and closing member 114 includes a left side plate 1141 and a right side plate 1144. A connecting rod 1143 is welded and fixed between the left side plate 1141 and the right side plate 1144. A shielding plate 1142 is welded and fixed on the right side plate 1144. The left side plate 1141 is slidably matched with the discharge channel 202. The right side plate 1144 is slidably matched with the reflux chamber 102. The shielding plate 1142 is slidably matched with the opening and closing groove 115. The right side of the right side plate 1144 is welded and fixed to the output shaft of the cylinder 116. The cylinder 116 is installed on the inner wall of the opening and closing groove 115 through bolts.

[0061] In combination with the attached Figure 4 and the attached Figure 6As shown, a squeezing assembly and an opening 205 are provided at the right end of the dehydration channel 203. The opening 205 is opened at the bottom of the right end of the dehydration channel 203. The squeezing assembly is used to generate resistance to block the feces in the dehydration channel 203 from passing through the opening 205. Specifically, the squeezing assembly includes a blocking member 206. Preferably, the blocking member 206 is of a conical structure. The blocking member 206 is slidably engaged with the dehydration channel 203, and a compression spring 207 is fixedly welded between the blocking member 206 and the inner wall of the dehydration channel 203.

[0062] The left end (the lower end) of the dehydration channel 203 is connected to a second separation pipe 4. The second separation pipe 4 is used to collect the liquid in the dehydration pipe (the liquid separated from the solid feces). Preferably, in this embodiment, the first separation pipe 3 and the second separation pipe 4 form a tee pipe structure. A pump assembly 6 and a pair of valves 7 are provided on the tee pipe. The valves 7 are used to respectively realize the on-off of the first separation pipe 3 and the second separation pipe 4. The pump assembly 6 is used to pump the livestock and poultry manure in the first separation pipe 3 and the second separation pipe 4 into the biological treatment module.

[0063] The biological treatment module is used to receive the separated liquid manure and perform biochemical treatment. In this embodiment, the biological treatment module mainly includes various treatment ponds 5 (which are prior arts and will not be elaborated here), such as a pre-explosion adjustment pond, an intermediate water pond, a hydrolysis acidification pond, an anaerobic pond (the anaerobic biological treatment unit includes an anaerobic reactor, a biogas collection and disposal system (a purification system, a gas storage tank, a gas transmission and distribution pipe, and a use system, etc.), and a biogas slurry and biogas residue disposal system), and a stripping pond, etc.

[0064] The solid manure treatment module is used to deeply treat the separated solid feces. For example, the deep treatment methods include composting fermentation, anaerobic digestion, etc., aiming to convert the solid feces into organic fertilizers or biomass energy (prior arts will not be elaborated here).

[0065] The specific implementation process is as follows: The preliminarily separated livestock and poultry manure is transported to the separation channel 101 in the first separation carrier 1 through a pump or pipeline. When the livestock and poultry manure passes through the reflux chamber 102, it will be divided into two streams of fluid. One stream continues to be transported along the separation channel 101, and the other stream flows into the reflux chamber 102, changes its flow direction, and impacts the fluid flowing normally in the separation channel 101 (refer to the reverse movement principle of the Tesla valve), thereby generating reflux or vortices in the local areas of the reflux chamber 102 and the separation channel 101, accelerating the sedimentation of the solid part in the fluid, and adhering and accumulating in the reflux chamber 102. As the reflux chamber 102 is gradually filled with the solid part, the reflux chamber 102 will no longer generate resistance. At this time, the flow rate collected by the flow rate sensor 103 will gradually increase to a higher speed range (the flow rates collected by all the flow rate sensors 103 in the separation channel 101 are plotted as an image of a continuous piecewise function curve (the abscissa is the distance of the separation channel 101, and the ordinate is the flow rate), each small segment is a quadratic function curve, and the lowest flow rate of the previous small segment is the highest flow rate of the next small segment). The fluid in the separation channel 101 continues to be transported along the separation channel 101 until it passes through the next reflux chamber 102, and the above process is repeated.

[0066] When the control unit collects that the flow rate of the flow rate sensor 103 is higher than the preset threshold (the flow rate sensor 103 at the leftmost end in the separation channel 101 reaches the preset threshold first), the control unit controls the cylinder 116 to operate, pushes the opening and closing member 114 out of the opening and closing groove 115, and the left side plate 1141 and the right side plate 1144 push the solid manure accumulated in the reflux chamber 102 into the discharge channel 202, so that it falls into the dehydration channel 203 along the discharge channel 202. Then, the driving member 201 (servo motor) is started to rotate the screw 204. The screw 204 pushes the solid manure falling into the dehydration channel 203 upward along the dehydration channel 203 until it abuts against the blocking member 206. The liquid in the solid manure is gradually compressed and extruded. After the liquid is extruded, it falls back to the bottom of the dehydration channel 203 and is then pumped away by the second separation pipe 4, while the solid manure is discharged through the opening 205, collected by a small cart, and transferred to the solid manure treatment module for in-depth treatment.

[0067] The livestock and poultry manure that has been separated layer by layer in the separation channel 101 is pumped into the treatment pool 5 by the pump assembly 6 along the first separation pipe 3 for biochemical treatment.

[0068] The difference between Example 2 and the above Example 1 is only that a pretreatment mechanism is further provided between the diversion channel and the first separation tube 3; the pretreatment mechanism includes an extrusion chamber 104, and the extrusion chamber 104 is opened in the first separation carrier 1; piston plates 107 are symmetrically arranged in the extrusion chamber 104. In this embodiment, the piston plates 107 are respectively located at the top and bottom of the extrusion chamber 104, and extrusion springs 106 are adhesively fixed between the piston plates 107 and the extrusion chamber 104. The piston plates 107 are all slidably matched with the extrusion chamber 104; a piston block 108 is slidably matched in the middle of the extrusion chamber 104. A lower return channel 109 and an upper return channel 110 are opened in the piston block 108. The upper return channel 110 and the lower return channel 109 are arranged in central symmetry. Combined with the attached Figure 5 As shown, the structures of the upper return channel 110 and the lower return channel 109 are respectively in the shape of "┛" and "┏". The upper return channel 110 and the lower return channel 109 are respectively communicated with the top and bottom of the extrusion chamber 104. Activated carbon filter plates 113 are fixed between the piston block 108 and the piston plates 107 by bolts. Ring-shaped pipes 105, a first outlet 111 and a second outlet 112 are further communicated on the left and right sides of the extrusion chamber 104; the ring-shaped pipe 105 is used to alternately communicate the separation channel 101 with the upper return channel 110 and the lower return channel 109, and the whole ring-shaped pipe 105 presents a semicircular shape; the first outlet 111 and the second outlet 112 are used to alternately communicate with the extrusion chamber 104 based on the movement of the piston block 108; both the first outlet 111 and the second outlet 112 are communicated with the first separation tube 3.

[0069] Specific implementation process: When the livestock and poultry manure in the diversion channel (liquid manure) enters the annular pipe 105 after being separated layer by layer, when the annular pipe 105 (left side) is communicated with the upper return channel 110, the liquid manure flows out of the upper return channel 110, passes through the activated carbon filter plate 113 (first adsorption), enters the top of the extrusion chamber 104, and as the liquid manure continuously accumulates at the top of the extrusion chamber 104, the piston block 108 will be continuously squeezed downward, so that the piston block 108 moves downward until the second outlet 112 is exposed. The liquid manure passes through the activated carbon filter plate and is discharged from the second outlet 112 under the synergistic action of the compression spring 207 (second adsorption). At the same time, when the piston block 108 moves downward until the lower return channel 109 is communicated with the annular pipe 105 (at this time, the upper return channel 110 is disconnected from the annular pipe 105), the liquid manure enters the lower return channel 109 from the annular pipe 105 (right side) and continuously accumulates at the bottom of the extrusion chamber 104, so that the pressure at the bottom of the extrusion chamber 104 increases, lifting the piston block 108 upward until the first outlet 111 is exposed, and the liquid manure is discharged from the first outlet 111. At the same time, the upper return channel 110 is communicated with the annular pipe 105 (left side) again. During the whole process, the liquid manure also passes through the activated carbon filter plate 113 twice. As the liquid manure is continuously input into the extrusion chamber 104, the above process is repeated continuously, ensuring that the liquid manure passes through the activated carbon filter twice repeatedly in the pretreatment mechanism, effectively improving the treatment efficiency and quality.
