Description

Technical Field

[0001] The invention belongs to the technical field of livestock and poultry manure treatment, and in particular is a high-efficiency livestock and poultry manure treatment system for breeding farms. Background Art

[0002] In modern livestock and poultry farming, with the continuous expansion of farming scale and the improvement of intensiveness, 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 nutrients, but also contains pathogens, heavy metals and other harmful substances. If it is not properly treated and directly discharged into the environment, it will cause serious pollution to the soil, water and air, affecting the ecological balance and human health.

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

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

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

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

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

[0008] An efficient livestock and poultry manure treatment system for a breeding farm includes 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 particles of impurities and sand and gravel from 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, the separation channel is connected with a first separation tube, and the first separation tube 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 reflux generated by the flow of 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 feces and sewage and perform biochemical treatment;

[0012] The solid feces treatment module is used to carry out deep treatment of the separated solid feces.

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

[0014] 1. In this solution, after removing large particles of 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 solid feces from mixed feces based on the reflux effect generated by the flow of livestock and poultry feces. This step not only improves the separation efficiency, but also reduces the difficulty and cost of subsequent processing. Subsequently, the dehydration component in the second separation carrier further dehydrates the solid feces and removes the excess liquid components, making the separation of solid and liquid feces more thorough.

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

[0016] 3. The whole treatment system of this solution has a clear process, and the modules work together to significantly improve the treatment efficiency of livestock and poultry manure. At the same time, due to the thorough separation of solid and liquid, the energy consumption and material consumption in the subsequent treatment process are reduced, and the treatment cost is reduced.

[0017] Furthermore, the solid separation component includes a plurality of reflux chambers, which are arranged along the length direction of the separation channel. The reflux chambers are used to separate livestock and poultry manure in the separation channel into a mainstream and a tributary. When the tributary meets the mainstream, the flow direction of the tributary is contrary to that of the mainstream.

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

[0019] The structure of the reflux chamber and the separation channel is similar to that of a Tesla valve. The Tesla valve generates resistance when it flows in reverse, causing turbulence and reflux in livestock and poultry manure 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, and the flow of manure in the separation channel returns to normal, and then enters the next reflux chamber, repeating the above process. This continuous process ensures the continuity and efficiency of solid-liquid separation.

[0020] Furthermore, the separation channel is arranged at an inclination.

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

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

[0023] Beneficial effect: Since the reflux chamber is located at the bottom, the deposited solid particles are not easily disturbed by the water flow and resuspended. 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 opened in the second separation carrier, the dehydration channel is arranged at an angle, the screw and the dehydration channel rotate in cooperation, and the driving member is used to drive the screw to rotate; the dehydration channel and each reflux chamber are connected with a discharge channel, and the reflux chamber is provided with an opening and closing component, and the opening and closing component is used to realize the connection and disconnection between the reflux chamber and the discharge channel and between the reflux chamber and the separation channel; an extrusion component and an opening are provided at one end of the dehydration channel away from the driving member, and the opening is located at the higher end of the dehydration channel, and the extrusion component is used to generate resistance to prevent feces in the dehydration channel from passing through the opening; the dehydration channel is connected with a second separation tube at one end away from the opening, and the second separation tube is used to collect liquid in the dehydration pipe.

[0025] Beneficial effect: when the solid feces in the reflux chamber is filled with, the partition between the reflux chamber and the separation channel is cut off by starting the opening and closing component, and the reflux chamber is connected to the dehydration channel at the same time, and the solid feces in the reflux chamber slides into the dehydration channel under the action of its own gravity, and the driving part is started to rotate the screw, and the rotation of the screw transports the solids in the dehydration channel to the opening along the dehydration channel respectively. Through the coordinated action of the screw and the extrusion component, sufficient resistance can be generated to squeeze the solid feces, thereby effectively removing the moisture therein, and the dehydrated solid feces is squeezed open by the extrusion component under the continuous conveyance of the screw, and thus discharged through the opening.

[0026] Furthermore, 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 effect: The compression force exerted by the compression spring on the blocking member requires 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 pressure 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 water is squeezed out. The presence of the compression spring ensures the continuity and stability of the dehydration process, and avoids incomplete dehydration due to insufficient pressure.

[0028] Due to the squeezing force of the compression spring, the solid feces cannot easily squeeze out the blocking member when the solid feces are not dehydrated enough, which effectively prevents the solid feces that are not fully dehydrated from being discharged prematurely.

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

[0030] Beneficial effect: When the reflux chamber is filled, the reflux chamber will no longer generate reflux and resistance (for the fluid in the distance before the reflux chamber). At this time, the fluid flow rate in this distance will increase. When the flow rate reaches the preset flow rate, the control unit determines that the reflux chamber is filled, and starts the cylinder to close the reflux chamber, and the solid feces in the reflux chamber slides into the dehydration channel for dehydration.

[0031] The flow rate sensor monitors the flow rate of the fluid flowing through each reflux chamber in real time, and the control unit can accurately determine the filling status of each reflux chamber based on the flow rate data. When the reflux chamber is filled, the flow rate of the fluid in this distance will increase. When the preset flow rate is reached, the control unit can determine that the reflux chamber is full. Based on the information from the flow rate sensor, the control unit can automatically start the cylinder to close the reflux chamber and slide the solid feces. This automated control reduces manual intervention and improves 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. 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 arranged between the diversion channel and the first separation tube; the pretreatment mechanism includes an extrusion chamber; piston plates are symmetrically arranged in the extrusion chamber, extrusion springs are arranged between the piston plates and the extrusion chamber, and the piston plates are slidably matched with the extrusion chamber; a piston block is slidably matched in the middle of the extrusion chamber, a lower circular channel and an upper circular channel are arranged in the piston block, the upper circular channel and the lower circular channel are centrally symmetrically arranged, the upper circular channel and the lower circular channel are respectively connected to the two ends of the extrusion chamber, an activated carbon filter plate is arranged between the piston block and the piston plate, and the activated carbon filter plate is fixedly connected to the piston block; an annular pipe, a first outlet and a second outlet are also connected on both sides of the extrusion chamber; the annular pipe is used to alternately connect the separation channel with the upper circular channel and the lower circular channel; the first outlet and the second outlet are used to alternately connect with the extrusion chamber based on the movement of the piston block; the first outlet and the second outlet are both connected to the first separation tube.

[0034] Beneficial effect: the livestock and poultry manure (liquid) treated by the solid separation component is input into the extrusion chamber through the annular pipe. When the annular pipe is connected with the upper circular channel, the livestock and poultry manure gradually accumulates at one end of the extrusion chamber, so that the piston block moves to the other end of the extrusion chamber. When the annular pipe is connected with the lower circular channel, the livestock and poultry manure gradually accumulates at the other end of the extrusion chamber, so that the piston block moves in the opposite direction, so that the piston block moves back and forth continuously, and the livestock and poultry manure in the extrusion chamber is discharged through the first outlet and the second outlet. After the livestock and poultry manure enters the extrusion chamber, the livestock and poultry manure will repeatedly pass through the activated carbon filter plate under pressure, and the heavy metals and other harmful substances in the livestock and poultry manure will be removed by the activated carbon filter plate.

[0035] The reciprocating motion of the piston block in the extrusion chamber repeatedly guides the livestock and poultry manure through the activated carbon filter plate. This dynamic filtration process not only improves the filtration efficiency, but also more effectively removes heavy metals and other harmful substances in the manure. Compared with static filtration, dynamic filtration can better utilize the adsorption capacity of activated carbon, ensuring higher quality of treated manure.

[0036] The pretreatment mechanism uses the pressure of livestock and poultry manure to push the piston block to move, without the need for an additional power source, thus achieving automated processing and reducing energy consumption. At the same time, by alternately connecting the upper circular channel and the lower circular channel, a continuous and stable processing process is achieved.

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

[0038] Furthermore, the first separation tube and the second separation tube form a three-way pipe structure; a pump assembly and a pair of valves are provided on the three-way pipe, the valves are used to respectively realize the opening and closing of the first separation tube and the second separation tube, and the pump assembly is used to pump the livestock and poultry manure in the first separation tube and the second separation tube into the biological treatment module.

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

[0040] Furthermore, the opening and closing parts include a left plate and a right plate; a connecting rod is arranged between the left plate and the right plate, and a baffle is arranged on the right plate; the left plate slides with the discharge channel, the right plate slides with the reflux chamber, the baffle slides with the opening and closing groove, and the right plate is fixedly connected to the output shaft of the cylinder.

[0041] Beneficial effect: When the solid feces in the reflux chamber needs to be pushed into the discharge channel, the right side plate is pushed to move by the cylinder, thereby driving the left side plate to move, and at the same time the baffle plate moves synchronously with the right side plate, transferring the solid feces from the reflux chamber to the discharge channel while isolating the separation channel from the reflux chamber.

[0054] The following is further described in detail through specific implementation methods:

[0055] Embodiment 1 is basically as attached Figures 1-8 As shown: A high-efficiency livestock and poultry manure treatment system for a breeding farm, mainly including 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 produced by livestock and poultry farms. Liquid manure refers to the liquid waste produced by livestock and poultry farms, including livestock and poultry urine, residual manure and wastewater generated during the production process. Solid manure refers to the solid waste produced by livestock and poultry farms, including manure and feed residues. 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 particles of impurities and sand and gravel from the collected livestock and poultry manure; the preliminary separation module corresponds to the livestock and poultry manure pretreatment project, which mainly includes screens and grit chambers. Large particles of impurities and sand and gravel are removed through physical methods such as screens or screens and grit chambers to prevent these impurities from damaging subsequent processing equipment. The livestock and poultry manure that has been initially separated is transported to the solid-liquid separation module through a pump or pipeline.

[0057] The solid-liquid separation module comprises a first separation carrier 1 and a second separation carrier 2; a separation channel 101 is provided in the first separation carrier 1, preferably, in combination with an attachment Figure 3 As shown, the separation channel 101 is arranged at an angle. The separation channel 101 is connected to a first separation pipe 3, and the first separation pipe 3 is used to transport livestock and poultry manure in the separation channel 101 to the biological treatment module.

[0058] A solid separation component is provided 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 reflux generated by the flow of livestock and poultry manure; specifically, the solid separation component includes a plurality of reflux chambers 102, and the reflux chambers 102 are arranged along the length direction of the separation channel 101, and the reflux chambers 102 are used to separate the livestock and poultry manure in the separation channel 101 into a mainstream and a tributary.

Preferably, in this embodiment, the reflux chamber 102 is opened at the bottom of the separation channel 101, and in some other embodiments, the reflux chamber 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 component is provided in the second separation carrier 2. The dehydration component is used to receive the solid separated by the solid separation component and perform dehydration treatment. Figure 4 and attached Figure 6 As shown, the dehydration assembly includes a driving member 201 and a screw 204; a dehydration channel 203 is provided in the second separation carrier 2, the dehydration channel 203 is inclined, the screw 204 rotates in cooperation 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 by bolts, and the output shaft of the servo motor is axially fixed to the screw 204 by a coupling. Figure 7 As shown, the dehydration channel 203 is connected to each reflux chamber 102 via a discharge channel 202 , and an opening and closing component is provided in each reflux chamber 102 , which is used to realize the connection and disconnection between the reflux chamber 102 and the discharge channel 202 and 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 connected to an opening and closing groove 115, and the opening and closing member 114 is slidably matched with the opening and closing groove 115, and the cylinder 116 is used to drive the opening and closing member 114 to move. Figure 3 As shown, a plurality of flow rate sensors 103 are installed in the separation channel 101, and the flow rate sensors 103 are used to detect the flow rate of the fluid (livestock and poultry manure, the same below) flowing through each reflux chamber 102 respectively; the flow rate sensors 103 are electrically connected to a control unit, and the control unit is used to determine the filling status of each reflux chamber 102 based on the information of each flow rate sensor 103, and control the operation of the cylinder 116. Specifically, in combination with the attached Figure 7 and 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, and a baffle 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 baffle 1142 is slidably matched with the opening and closing groove 115, and the right side of the right side plate 1144 is welded and fixed to the output shaft of the cylinder 116, and the cylinder 116 is mounted on the inner wall of the opening and closing groove 115 by bolts.

[0061] Combined with Figure 4 and attached Figure 6As shown, the right end of the dehydration channel 203 is provided with a squeezing assembly and an opening 205, the opening 205 is opened at the bottom of the right end of the dehydration channel 203, and 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 a conical structure; the blocking member 206 is slidably matched with the dehydration channel 203, and a compression spring 207 is welded and fixed between the blocking member 206 and the inner wall of the dehydration channel 203.

[0062] The left end (lower end) of the dehydration channel 203 is connected to the second separation pipe 4, which is used to collect the liquid in the dehydration pipeline (liquid separated from the solid feces). Preferably, in this embodiment, the first separation pipe 3 and the second separation pipe 4 form a three-way pipe structure; the three-way pipe is provided with a pump assembly 6 and a pair of valves 7, the valves 7 are used to realize the opening and closing of the first separation pipe 3 and the second separation pipe 4 respectively, and 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 feces and sewage and perform biochemical treatment. In this embodiment, the biological treatment module mainly includes various treatment tanks 5 (this is the prior art and will not be described in detail), for example, a pre-explosion regulating tank, an intermediate water tank, a hydrolysis acidification tank, an anaerobic tank (the anaerobic biological treatment unit includes an anaerobic reactor, a biogas collection and disposal system (purification system, gas storage tank, gas distribution pipe and use system, etc.), a biogas slurry and biogas residue disposal system) and a stripping tank, etc.

[0064] The solid feces treatment module is used to perform deep treatment on the separated solid feces. For example, deep treatment methods include composting fermentation, anaerobic digestion, etc., aiming to convert the solid feces into organic fertilizer or biomass energy (the existing technology will not be described in detail).

[0065] The specific implementation process is as follows: the livestock and poultry manure that has undergone preliminary separation is transported to the separation channel 101 in the first separation carrier 1 through a pump or a pipeline. When the livestock and poultry manure passes through the reflux chamber 102, it will be divided into two waves of fluid, one wave continues to be transported along the separation channel 101, and the other wave flows into the reflux chamber 102, and after changing the flow direction, it impacts the fluid that normally flows in the separation channel 101 (refer to the reverse motion principle of the Tesla valve), thereby generating reflux or vortex in the reflux chamber 102 and the local area of ​​the separation channel 101, thereby 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 solid parts, 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 a continuous piecewise function curve (the horizontal axis is the distance of the separation channel 101, and the vertical axis 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), and 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 detects that the flow rate of the flow rate sensor 103 is higher than the preset threshold value (the flow rate sensor 103 at the far left end in the separation channel 101 reaches the preset threshold value first), the control unit controls the cylinder 116 to operate, pushes the opening and closing member 114 out of the opening and closing slot 115, and the left plate 1141 and the right plate 1144 push the solid feces 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, and then starts the driving member 201 (servo motor) to rotate the screw 204. The screw 204 pushes the solid feces that falls into the dehydration channel 203 upward along the dehydration channel 203 until it hits the blocking member 206, and the liquid in the solid feces is gradually compressed and squeezed out. After being squeezed out, the liquid falls back to the bottom of the dehydration channel 203, and then is drawn away by the second separation tube 4, and the solid feces is discharged through the opening 205, collected by the trolley and transferred to the solid feces treatment module for deep treatment.

[0067] The livestock and poultry manure and sewage after being separated layer by layer in the separation channel 101 is pumped into the treatment tank 5 along the first separation pipe 3 by the pump assembly 6 for biochemical treatment.

[0068] The difference between Example 2 and Example 1 is 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, which is opened in the first separation carrier 1; piston plates 107 are symmetrically arranged in the extrusion chamber 104, and 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 bonded and fixed between the piston plates 107 and the extrusion chamber 104, and the piston plates 107 are slidably matched with the extrusion chamber 104; a piston block 108 is slidably matched in the middle of the extrusion chamber 104, and a lower circular channel 109 and an upper circular channel 110 are opened in the piston block 108, and the upper circular channel 110 and the lower circular channel 109 are centrally symmetrically arranged, combined with the attached Figure 5 As shown, the structures of the upper circular channel 110 and the lower circular channel 109 are respectively in the shape of "┛" and "┏", and the upper circular channel 110 and the lower circular channel 109 are respectively connected to the top and the bottom of the extrusion chamber 104, and an activated carbon filter plate 113 is fixed between the piston block 108 and the piston plate 107 by bolts. The left and right sides of the extrusion chamber 104 are also connected with an annular pipe 105, a first outlet 111 and a second outlet 112; the annular pipe 105 is used to alternately connect the separation channel 101 with the upper circular channel 110 and the lower circular channel 109, and the annular pipe 105 is semicircular as a whole; the first outlet 111 and the second outlet 112 are used to alternately connect with the extrusion chamber 104 based on the movement of the piston block 108; the first outlet 111 and the second outlet 112 are both connected to the first separation pipe 3.

[0069] Specific implementation process: When the livestock and poultry manure in the diversion channel is separated layer by layer (liquid manure) and enters the annular pipe 105, when the annular pipe 105 (left side) is connected with the upper circular channel 110, the liquid manure flows out of the upper circular channel 110 and passes through the activated carbon filter plate 113 (first adsorption) and enters the top of the extrusion chamber 104. As the liquid manure accumulates on 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, and 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 to the lower circular channel 109 and connects with the annular pipe 105 (at this time, the upper circular channel 110 is disconnected from the annular pipe 105), the liquid feces and sewage enter the lower circular channel 109 from the annular pipe 105 (right side), and continuously accumulate at the bottom of the extrusion chamber 104, thereby increasing the pressure at the bottom of the extrusion chamber 104, lifting the piston block 108 upward until the first outlet 111 is exposed, and the liquid feces and sewage are discharged from the first outlet 111, and at the same time, the upper circular channel 110 is connected with the annular pipe 105 again (left side), and the liquid feces and sewage also pass through the activated carbon filter plate 113 twice during the whole process. As the liquid feces and sewage are continuously input into the extrusion chamber 104, the above process is repeated continuously, ensuring that the liquid feces and sewage are repeatedly filtered by activated carbon twice in the pretreatment mechanism, effectively improving the treatment efficiency and quality.
