Description

Technical Field

[0001] This application relates to the technical field of waste liquid treatment equipment, and in particular to a waste liquid recovery and treatment device for a liquid phase detection and analysis pipeline. Background Technology

[0002] In liquid chromatography, liquid chromatography-mass spectrometry, and other liquid phase detection processes, waste liquid containing various components such as organic solvents, buffer salts, and analyte residues is generated. This type of waste liquid has a complex composition and some components are corrosive and toxic. Direct discharge would cause serious environmental pollution. At the same time, some components have recycling value, so they need to be properly disposed of through dedicated recycling and treatment devices. Existing liquid phase detection and analysis pipeline waste liquid recycling and treatment devices mostly use a single collection box for centralized collection and subsequent unified treatment. A few devices with separation functions mostly rely on static sedimentation or externally powered centrifugal separation structures. However, these existing devices have problems such as low processing efficiency and inability to achieve accurate classification and recycling of waste liquid components of different densities.

[0003] Patent (CN 112679028 A) discloses a medical waste liquid collection, separation, and treatment device. The device includes a filtration unit and a separation unit. The filtration unit comprises a filter box and a purification box. The filter box is mounted on the purification box. A horizontal partition plate is installed inside the purification box, dividing the space within the purification box into an adsorption chamber and a treatment chamber from top to bottom. One end of the adsorption chamber is connected to the lower end of the filter box, and the other end is connected to the treatment chamber. The filter box is a rectangular box with an open top and a bottom connection to the adsorption chamber. A first filter plate and a second filter plate are horizontally arranged inside the filter box. This patent can perform graded filtration of impurities in the waste liquid through the first and second filter plates in the filter box, followed by adsorption treatment in the adsorption chamber of the purification box and disposal in the treatment chamber, achieving preliminary purification of the waste liquid. However, it is limited to basic solid-liquid separation and simple adsorption purification of the waste liquid. For multi-component liquid phase detection and analysis pipeline waste liquid with complex composition and density differences, it cannot effectively achieve precise centrifugal separation and simultaneous classified recovery of waste liquid components with different densities.

[0004] Regarding the aforementioned technologies, the inventors believe that they suffer from the drawback of being unable to efficiently achieve precise separation and simultaneous classification and recycling of waste liquids of different densities. Summary of the Invention

[0005] To address the aforementioned technical problems, this application provides a waste liquid recovery and treatment device for liquid phase detection and analysis pipelines.

[0006] This application provides a waste liquid recovery and treatment device for liquid phase detection and analysis pipelines, which adopts the following technical solution: A waste liquid recovery and treatment device for liquid phase detection and analysis pipelines includes a separation unit and two sets of recovery units. The separation unit includes a separation shell, and a guide plate is provided inside the separation shell. The guide plate connects the driving zone and the separation zone of the separation shell and is arranged at an inclination. An impeller is rotatably arranged in the driving zone. A liquid inlet pipe is provided through the top of the separation shell, and one end of the liquid inlet pipe is tangentially positioned above the impeller. A driving separation component is fixedly arranged in the middle of the impeller, and one end of the driving separation component is located in the separation zone. The impeller is used to drive the driving separation component to rotate. A liquid outlet is provided on one side of the bottom of the separation shell. One set of recovery units is connected to the liquid outlet, and the other set of recovery units is connected to the driving separation component.

[0007] By adopting the above technical solution, the device utilizes the linkage structure between the impeller and the drive separation component, along with the tangential liquid inlet design of the inlet pipe. The kinetic energy generated by the liquid impacting the impeller causes the drive separation component to rotate within the separation zone. An inclined guide plate effectively separates the drive zone from the separation zone, guiding the waste liquid smoothly towards the separation zone while avoiding turbulence from the impeller's operation that could interfere with the separation process. Under the combined action of centrifugal force and gravity, waste liquids of different densities quickly stratify. Higher density components accumulate on the outer side or bottom of the separation zone, while lower density components concentrate on the relatively inner side or upper part. Compared to traditional static sedimentation, the separation efficiency is significantly improved, and the separation effect is more thorough. The device is equipped with two independent recovery units: one connected to the liquid outlet at the bottom of the separation shell to recover the high-density waste liquid components after separation; and the other connected to the drive separation component to recover the low-density waste liquid components. This achieves simultaneous classified recovery of waste liquids of different densities, eliminating the need for additional transfer or diversion equipment, simplifying the waste liquid recovery process, avoiding secondary pollution caused by mixing different waste liquid components, and enhancing the resource utilization potential of the recovered waste liquid.

[0008] Preferably, the drive separation assembly includes a rotating shaft and a rotating drum; the top of the rotating drum is provided with an opening, and the guide plate is connected to the inside of the rotating drum through the opening; the rotating drum is provided with multiple sets of ejection holes in its circumference; one end of the rotating shaft passes through the top of the separation housing, and the rotating shaft is rotatably connected to the separation housing; the other end of the rotating shaft is fixedly connected to the inside of the rotating drum, and the rotating shaft is fixedly mounted on the impeller; the bottom of the rotating drum is provided with an outlet, and the outlet is provided with a rotating interface, and the outlet is connected to the recovery unit through the rotating interface.

[0009] By adopting the above technical solution, the top opening of the rotating drum receives the waste liquid guided by the diversion plate. When the impeller drives the rotating shaft and the rotating drum to rotate synchronously, the waste liquid inside the rotating drum is subjected to centrifugal force. The high-density components are quickly thrown towards the drum wall and discharged to the separation zone through multiple sets of circumferential discharge holes. The low-density components remain inside the rotating drum and are eventually recovered through the bottom outlet, realizing the directional screening and separation of density components. This effectively avoids the backflow and mixing of components of different densities. At the same time, the rigid connection between the rotating shaft and the separation shell, impeller, and rotating drum ensures the coaxiality of the rotating drum, avoids vibration problems caused by eccentricity, and improves the stability of the device operation. The bottom outlet of the rotating drum is connected to the recovery unit through a rotating interface. This connection method ensures the sealing of the waste liquid recovery during the rotation of the rotating drum and does not affect the rotation of the drum.

[0010] Preferably, the recovery unit includes a reaction tank, a first pipeline, and a wastewater tank; one end of the first pipeline is connected to the reaction tank; in one set of the recovery unit, the other end of the first pipeline is connected to the liquid outlet, and in another set of the recovery unit, the other end of the first pipeline is connected to the rotating interface; a switch port is provided at the bottom of the reaction tank, and the reaction tank is connected to the wastewater tank through the switch port, and the wastewater tank is detachably connected to the reaction tank.

[0011] By adopting the above technical solution, the two sets of recovery units are connected to the liquid outlet of the separation shell and the rotating interface at the bottom of the rotating drum through the first pipeline, respectively, which can accurately receive high-density and low-density waste liquids after centrifugal separation. After the waste liquid enters the corresponding reaction tank, it completes pretreatment operations such as sedimentation and neutralization in the reaction tank, avoiding the pollution risks caused by direct discharge or transfer.

[0012] Preferably, a float is provided inside the reaction vessel, the float is slidably disposed on one side of the reaction vessel, and a switch assembly is provided inside the reaction vessel.

[0013] Preferably, a switching valve is provided inside the switching port, the switching valve including a ball, a valve shaft, a connecting rod, and a slider; the ball is provided with a through hole, the ball is rotatably disposed inside the switching port, the valve shaft is disposed through one side of the switching port, and the valve shaft is rotatably connected to the switching port; one end of the valve shaft is fixedly disposed on the ball, and one end of the connecting rod is fixedly disposed on the other end of the valve shaft; the slider is slidably disposed on the connecting rod.

[0014] By adopting the above technical solution, the switching valve adopts a ball valve core structure. When the through hole on the ball is connected to the switching port, the waste liquid flows smoothly into the wastewater tank. The ball can completely block the switching port when it rotates, and quickly complete the on / off switching of the switching port. The ball valve core is driven to rotate by the drive linkage to realize the opening and closing control of the switching port.

[0015] Preferably, the switching assembly includes a driving cavity, a trigger block, a starting cavity, a closing block, a closing cavity, and a driving rod. The starting cavity is disposed in the wall at the top of the reaction vessel. One end of the trigger block is slidably disposed in the starting cavity, and the other end of the trigger block is disposed in the reaction vessel. The closing cavity is disposed in the wall at the bottom of the reaction vessel. One end of the closing block is slidably disposed in the closing cavity, and the other end of the closing block is disposed in the reaction vessel. The driving cavity is disposed in the wall on one side of the reaction vessel. One end of the driving cavity is connected to the starting cavity, and the other end of the driving cavity is connected to the closing cavity. One end of the driving rod is slidably disposed in the driving cavity, and the other end of the driving rod is rotatably connected to the slider.

[0016] By adopting the above technical solution, when the liquid level of the waste liquid rises to the preset height, the float abuts against the trigger block, triggering the drive rod to slide in the drive chamber, driving the connecting rod and valve shaft to rotate, so that the ball valve core through hole opens the switch port; when the liquid level of the waste liquid drops to the preset low level, the float falls back to abut against the closing block, the drive rod slides in the opposite direction, driving the ball valve core to rotate and block the switch port, accurately controlling the residence volume and pretreatment time of the waste liquid in the reaction tank, ensuring that neutralization, flocculation and other reactions are fully carried out.

[0017] Preferably, a storage tank is provided on the reaction vessel in a single recovery unit. The storage tank has a first inlet at its bottom and is connected to the corresponding reaction vessel through the first inlet. A first feeding port is provided on the top of the storage tank. A sliding rod is provided inside the storage tank, passing through the storage tank and slidably connected to it. A baffle is slidably provided on the first inlet and is fixedly connected to one end of the sliding rod.

[0018] By adopting the above technical solution, the storage tank pre-stores flocculants and other pretreatment agents through the first feeding port at the top, and the first inlet at the bottom is connected to the reaction tank. By controlling the sliding stroke of the sliding rod, the opening and closing range of the baffle can be precisely adjusted, thereby controlling the injection rate and injection of the agent, achieving the effect of quantitative injection of flocculants, and improving the flocculation and sedimentation efficiency.

[0019] Preferably, a speed reducer is provided on the separation housing, and the input end of the speed reducer is connected to one end of the rotating shaft; the other end of the speed reducer is provided with a drive assembly, which is used to drive the sliding rod to slide.

[0020] By adopting the above technical solution, the rotating shaft rotates at high speed with the impeller, and its speed fluctuates due to the influence of the waste liquid inlet flow rate. The input end of the reducer is connected to the rotating shaft, which can convert the high-speed unstable rotation of the rotating shaft into the low-speed uniform motion of the drive component. This allows the power speed output by the drive component to be precisely matched with the required speed for reagent dosing, avoiding problems such as excessive opening and closing of the baffle and loss of control over the dosage due to excessive rotating shaft speed, or excessively long dosing interval and insufficient flocculation reaction due to excessively slow speed. This ensures the stability and consistency of quantitative dosing.

[0021] Preferably, the drive assembly includes a cam, a push rod, and a retaining spring; the cam is disposed at the output end of the reducer, one end of the push rod is fixedly disposed at the other end of the sliding rod, and the other end of the push rod abuts against the cam; the retaining spring is sleeved on the other end of the sliding rod, one end of the retaining spring is fixedly disposed on the outside of the storage box, and the other end of the retaining spring is fixedly disposed on the push rod.

[0022] By adopting the above technical solution, the cam is fixed at the output end of the reducer. The reducer converts the high-speed rotation of the rotating shaft into the low-speed uniform rotation of the cam. During the rotation of the cam, its contour surface continuously abuts against the push rod. Through the eccentric structure of the cam, its own rotational motion is converted into the reciprocating linear motion of the push rod, which in turn drives the sliding rod and the baffle to reciprocate synchronously, realizing the periodic opening and closing of the baffle. In conjunction with the number of rotations of the rotating shaft, the duration and amount of reagent addition in each round are precisely controlled, ensuring that the flocculant enters the reaction tank intermittently and quantitatively, and is uniformly mixed with the waste liquid.

[0023] Preferably, the reaction tank in the other set of recovery units is equipped with a neutralization tank, and the top of the neutralization tank is equipped with a second feeding port; one end of the neutralization tank is equipped with a feed port, and the neutralization tank is connected to the reaction tank in the other set of recovery units through the feed port, and the feed port is equipped with a first one-way valve; a partition is provided inside the neutralization tank, and the partition divides the neutralization tank into a storage area and a pumping area; one end of the partition is equipped with an extraction port, and the extraction port is equipped with a second one-way valve; a pumping mechanism is provided in the pumping area, and the pumping mechanism includes a pumping rod, a piston rod, and a piston block; the piston block is slidably disposed in the pumping area, one end of the piston rod is fixedly disposed in the piston block, and the other end of the piston rod passes through the other end of the neutralization tank, and the piston rod is slidably connected to the neutralization tank; one end of the pumping rod is fixedly connected to the other end of the piston rod, and the other end of the pumping rod is fixedly connected to the sliding rod.

[0024] By adopting the above technical solution, the pumping mechanism is rigidly connected to the sliding rod via the pumping rod. The reciprocating linear motion of the sliding rod can directly drive the piston rod and piston block to slide synchronously in the pumping zone. When the piston block slides outward, a negative pressure is formed in the pumping zone, and the neutralizing agent in the storage zone opens the second one-way valve and flows into the pumping zone through the extraction port. When the piston block slides inward, the pressure in the pumping zone increases, and the neutralizing agent opens the first one-way valve and is pumped into the reaction tank through the delivery port. The automatic quantitative replenishment of the neutralizing agent can be achieved by relying on the linkage of the sliding rod, which can accurately match the neutralization reaction requirements of low-density waste liquid. Through targeted neutralization pretreatment, the pH of low-density waste liquid can be effectively adjusted to meet the emission standards or resource recovery requirements.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The top opening of the rotating drum receives the waste liquid guided by the diversion plate. When the impeller drives the rotating shaft and the rotating drum to rotate synchronously, the waste liquid inside the rotating drum is subjected to centrifugal force. The denser components are quickly thrown towards the drum wall and discharged to the separation zone through multiple sets of circumferential discharge holes. The less dense components remain inside the rotating drum and are eventually recovered through the bottom outlet, realizing the directional screening and separation of density components. This effectively avoids the backflow and mixing of components of different densities. At the same time, the rigid connection between the rotating shaft and the separation shell, impeller, and rotating drum ensures the coaxiality of the rotating drum, avoids vibration problems caused by eccentricity, and improves the stability of the device operation. The bottom outlet of the rotating drum is connected to the recovery unit through a rotating interface. This connection method ensures the sealing of the waste liquid recovery during the rotation of the rotating drum and does not affect the rotation of the drum.

[0026] 2. The two sets of recovery units are connected to the liquid outlet of the separation shell and the rotating interface at the bottom of the rotating drum via the first pipeline, respectively, which can accurately receive high-density and low-density waste liquids after centrifugal separation. After the waste liquid enters the corresponding reaction tank, it undergoes pretreatment operations such as sedimentation and neutralization in the reaction tank to avoid the pollution risks caused by direct discharge or transfer.

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses a waste liquid recovery and treatment device for liquid phase detection and analysis pipelines. (Refer to...) Figure 1 and Figure 2 The system includes a separation unit 1 and two sets of recovery units 2. The separation unit 1 includes a separation housing 11, inside which a guide plate 111 is provided. The guide plate 111 connects the driving zone 112 and the separation zone 113 of the separation housing 11, and the guide plate 111 is arranged at an inclination. An impeller 12 is rotatably arranged in the driving zone 112. An inlet pipe 13 is provided through the top of the separation housing 11, and one end of the inlet pipe 13 is tangentially arranged above the impeller 12. The mixed waste liquid discharged from the liquid phase detection pipeline enters the driving zone 112 of the separation housing 11 through the tangentially arranged inlet pipe 13. A driving separation component 15 is fixedly arranged in the middle of the impeller 12, and one end of the driving separation component 15 is arranged in the separation zone 113. The impeller 12 is used to drive the driving separation component 15 inside the separation housing 11 to rotate. An outlet 14 is provided on one side of the bottom of the separation housing 11. The single set of recovery units 2 is connected to the outlet 14.

[0035] The drive separation assembly 15 includes a rotating shaft 151 and a rotating drum 152. The top of the rotating drum 152 has an opening 1521, through which a guide plate 111 connects to the inside of the rotating drum 152. The mixed waste liquid is guided by the inclined guide plate 111 and enters the drum through the opening 1521 at the top of the rotating drum 152. Multiple sets of ejection holes 1522 are arranged circumferentially around the rotating drum 152. One end of the rotating shaft 151 penetrates the top of the separation housing 11, and the rotating shaft 151 is rotatably connected to the separation housing 11. The other end of the rotating shaft 151 is fixedly connected to the inside of the rotating drum 152. The rotating shaft 151 is fixedly mounted on the impeller 12. The impact force of the waste liquid drives the impeller 12 to rotate, and the impeller 12 synchronously drives the rotating shaft 151 and the rotating drum 152 to rotate at high speed. Under the centrifugal force generated by the high-speed rotation of the rotating drum 152, the waste liquid components with higher density are subjected to stronger centrifugal force and are thrown towards the inner wall of the rotating drum 152. They are discharged into the separation zone 113 through the circumferential discharge hole 1522, and collect at the liquid outlet 14 at the bottom of the separation shell 11, flowing into the corresponding set of recovery units 2. The bottom of the rotating drum 152 is provided with an outlet 1523, and a rotating interface 1524 is provided on the outlet 1523. The outlet 1523 is connected to another set of recovery units 2 through the rotating interface 1524. The waste liquid components with lower density are subjected to weaker centrifugal force and remain in the rotating drum 152. Finally, they flow into another set of recovery units 2 through the bottom outlet 1523 and the rotating interface 1524 of the rotating drum 152, completing the separation and classification recovery of waste liquids with different densities.

One end of the first pipeline 22 is connected to the reaction tank 21. In a single recycling unit 2, the other end of the first pipeline 22 is connected to the liquid outlet 14, and in another recycling unit 2, the other end of the first pipeline 22 is connected to the rotating interface 1524. A switch port 211 is provided at the bottom of the reaction tank 21, and the reaction tank 21 is connected to the wastewater tank 23 through the switch port 211. The wastewater tank 23 is detachable from the reaction tank 21. Disconnection; a float 212 is installed inside the reaction tank 21, and the float 212 is slidably installed on one side inside the reaction tank 21. The two sets of recovery units 2 are connected to the liquid outlet 14 of the separation shell 11 and the rotation interface 1524 of the rotating drum 152 respectively through the first pipeline 22. High-density waste liquid flows into the corresponding reaction tank 21, and low-density waste liquid flows into the other set of reaction tanks 21. The waste liquid is continuously injected, and the liquid level in the reaction tank 21 rises, causing the float 212 to float up synchronously; the switch port 211 is equipped with an opening... The valve 3 is a switch valve, comprising a ball 31, a valve shaft 32, a connecting rod 33, and a slider 34. The ball 31 has a through hole 311 and is rotatably mounted within a switch opening 211. The valve shaft 32 passes through one side of the switch opening 211 and is rotatably connected to it. One end of the valve shaft 32 is fixedly mounted on the ball 31, and one end of the connecting rod 33 is fixedly mounted on the other end of the valve shaft 32. The slider 34 is slidably mounted on the connecting rod 33. When the liquid level reaches a preset position, the float 2... 12 triggers a linkage action, which in turn drives the connecting rod 33 and valve shaft 32 to rotate; the valve shaft 32 drives the ball 31 to rotate, so that the through hole 311 on the ball 31 is connected to the switch port 211, and the pre-treated waste liquid flows into the detachable wastewater tank 23 through the switch port 211; when the wastewater tank 23 is full, it can be directly disassembled and replaced; when the liquid level in the reaction tank 21 drops to the preset position, the float 212 falls back, the switch valve 3 reverses its action, and the valve core of the ball 31 blocks the switch port 211, waiting for the next round of waste liquid injection.

The stop chamber 45 is located in the bottom wall of the reaction vessel 21. One end of the stop block 44 is slidably disposed in the stop chamber 45, and the other end of the stop block 44 is disposed in the reaction vessel 21. The drive chamber 41 is located in the side wall of the reaction vessel 21. One end of the drive chamber 41 is connected to the start chamber 43, and the other end of the drive chamber 41 is connected to the stop chamber 45. One end of the drive rod 46 is slidably disposed in the drive chamber 41, and the other end of the drive rod 46 is rotatably connected to the slider 34. Waste liquid enters... As the liquid level rises in reaction tank 21, float 212 rises synchronously. When the liquid level reaches the top, float 212 pushes against trigger block 42, causing trigger block 42 to slide into activation chamber 43. The displacement of trigger block 42 is transmitted through drive chamber 41, pushing drive rod 46 to slide within drive chamber 41. The other end of drive rod 46 is rotatably connected to slider 34 in switch valve 3. When drive rod 46 slides, it drives slider 34 to move along connecting rod 33, thereby pulling connecting rod 33 and valve shaft 32 to rotate, making the ball 31 valve core through hole 311 of switch valve 3 connected to switch port 211, and waste liquid flows into wastewater tank 23. After the waste liquid is discharged, float 212 falls back to the bottom and pushes against closing block 44, causing closing block 44 to slide into closing chamber 45. Drive rod 46 slides in the opposite direction through drive chamber 41, thereby driving valve shaft 32 and ball 31 valve core to rotate in the opposite direction, blocking switch port 211 and stopping liquid discharge.

After reduction and torque increase, the output end of the reducer 114 rotates at a stable speed. The drive assembly 6 includes a convex The system includes a wheel 61, a push rod 62, and a retaining spring 63. The cam 61 is located at the output end of the reducer 114. One end of the push rod 62 is fixedly mounted on the other end of the sliding rod 53, and the other end of the push rod 62 abuts against the cam 61. The retaining spring 63 is sleeved on the other end of the sliding rod 53. One end of the retaining spring 63 is fixedly mounted on the outside of the storage tank 5, and the other end is fixedly mounted on the push rod 62. During the rotation of the cam 61, the contour surface of the cam 61 pushes the push rod 62 in a reciprocating linear motion, thereby causing the sliding rod 53 to slide synchronously. When the protruding end of the cam 61 disengages from the push rod 62, the restoring force of the retaining spring 63 keeps the push rod 62 abutting against the contour surface of the cam 61. When the sliding rod 53 slides, it drives the baffle 54 to open and close, realizing the on / off control of the first inlet 51 at the bottom of the storage tank 5, thereby quantitatively and intermittently adding the reagent in the storage tank 5 into the reaction vessel 21.

The pumping mechanism 76 includes a pumping rod 761, a piston rod 762, and a piston block 763. The piston block 763 is slidably disposed in the pumping area 742. One end of the piston rod 762 is fixedly disposed on the piston block 763, and the other end of the piston rod 762 passes through the neutralization box. At the other end of 7, piston rod 762 is slidably connected to neutralization tank 7; one end of pump rod 761 is fixedly connected to the other end of piston rod 762, and the other end of pump rod 761 is fixedly connected to sliding rod 53; when sliding rod 53 moves in reciprocating linear motion, it synchronously drives pump rod 761 fixed on sliding rod 53 to move in reciprocating motion, thereby pulling piston rod 762 and piston block 763 to move in reciprocating sliding within pumping zone 742 of neutralization tank 7; when piston block 763 slides outward, negative pressure is formed in pumping zone 742, and neutralizing agent in storage zone 741 opens the second one-way valve 75 and flows into pumping zone 742 through extraction port 743; when piston block 763 slides inward, pressure in pumping zone 742 increases, neutralizing agent opens the first one-way valve 73 and is pumped into corresponding reaction tank 21 through delivery port 72 to mix with low-density waste liquid for neutralization reaction.

[0040] The working principle of the liquid phase detection and analysis pipeline waste liquid recovery and treatment device in this application is as follows: The mixed waste liquid discharged from the liquid phase detection pipeline enters the drive zone 112 of the separation shell 11 through the tangentially arranged inlet pipe 13. The impact force of the waste liquid drives the impeller 12 to rotate at high speed. The impeller 12 synchronously drives the rotating shaft 151 and the rotating drum 152 to rotate. The mixed waste liquid is guided by the inclined guide plate 111 and enters the drum through the top opening 1521 of the rotating drum 152. Under the centrifugal force generated by the high-speed rotation of the rotating drum 152, the waste liquid components with higher density are subjected to stronger centrifugal force and are thrown towards the inner wall of the rotating drum 152. They are discharged into the separation zone 113 through the circumferential throwing hole 1522 and collected at the bottom outlet 14 of the separation shell 11. The waste liquid flows into the corresponding set of recycling units 2; the waste liquid components with lower density are less affected by centrifugal force and remain in the rotating drum 152. They then flow into another set of recycling units 2 through the bottom outlet 1523 and rotating interface 1524 of the rotating drum 152, completing the preliminary classification and separation of waste liquids of different densities; when the rotating shaft 151 rotates, it drives the reducer 114 to operate, driving the cam 61 to rotate at a low and uniform speed. During the rotation of the cam 61, the contour surface of the cam 61 pushes the push rod 62 to perform reciprocating linear motion, causing the sliding rod 53 to slide synchronously; the restoring force of the spring 63 pulls the push rod 62 and the sliding rod 53 to return to their original positions, and the push rod 62 and the cam 61 remain in contact. When the sliding rod 53 slides, it drives the first inlet 5 at the bottom of the storage tank 5. The baffle 54 at point 1 opens and closes repeatedly, thereby quantitatively and intermittently adding the flocculant from storage tank 5 into the corresponding reaction tank 21, where it is mixed with high-density waste liquid for flocculation pretreatment. When the sliding rod 53 reciprocates linearly, it simultaneously drives the pump rod 761 to reciprocate, which in turn pulls the piston rod 762 and piston block 763 to reciprocate within the pumping zone 742 of the neutralization tank 7. When the piston block 763 slides outward, a negative pressure is formed in the pumping zone 742, and the neutralizing agent in storage zone 741 opens the second one-way valve 75 and flows into the pumping zone 742 through the extraction port 743. When the piston block 763 slides inward, the pressure in the pumping zone 742 increases, and the neutralizing agent opens the first one-way valve 73 and is pumped into the corresponding reaction tank 21 through the delivery port 72. The waste liquid is mixed with low-density waste liquid in the reaction tank 21 for neutralization and pretreatment. The pretreated waste liquid gradually accumulates in the reaction tank 21, and the liquid level rises, causing the float 212 to float synchronously. When the liquid level reaches the upper limit threshold, the float 212 pushes against the trigger block 42 in the activation chamber 43. The displacement of the trigger block 42 is transmitted through the drive chamber 41, which pushes the drive rod 46 to slide in the drive chamber 41. The other end of the drive rod 46 is rotatably connected to the slider 34 of the switch valve 3. When the drive rod 46 slides, it drives the slider 34 to move along the connecting rod 33, which in turn pulls the connecting rod 33 and the valve shaft 32 to rotate, so that the ball 31 valve core through hole 311 of the switch valve 3 is connected to the switch port 211, and the waste liquid flows into the detachable wastewater tank 23.After the waste liquid is discharged, the liquid level in reaction tank 21 drops to the lower threshold. The float 212 falls back and pushes against the closing block 44 in the closing chamber 45. This, through the driving chamber 41, drives the driving rod 46 to slide in the opposite direction, causing the valve shaft 32 and the valve core of the ball 31 to rotate in the opposite direction, sealing the switch port 211 and stopping the discharge. Once the wastewater tank 23 is full, it can be directly disassembled and replaced, awaiting the next round of waste liquid treatment.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
