[0010] The mixing plate A and the mixing plate B are both made of spiral twisting. Sealing plates are rotatably installed on both sides of the mixing plate A through bearings. The sealing plates on both sides are opposite to the through grooves. The sealing plates slide on the cross bar following the mixing plate A. The sealing plates seal both ends of the mixing plate A to prevent waste water from entering the through grooves. The first spring connects the sealing plate on the right side with the transmission shaft. The first spring is sleeved on the cross bar. The first spring is electrically connected to the control system. The sealing plate is rotatably installed on the cross bar through bearings, so that when the first spring pulls the mixing plate A to rotate, the sealing plate and the first spring do not rotate.

[0011] The surface of the mixing plate A is provided with a plurality of filter grooves, the filter membrane is arranged in the middle of the filter groove, one side of the filter groove is connected to the inlet of the air slip ring A through a pipeline, the outlet of the air slip ring A is connected to the inside of the transmission shaft through a bellows, and the air slip ring A is installed on the transmission shaft;

[0012] Two sets of fixed shafts are arranged on the mixing plate A on the other side of the filter tank, and a telescopic plate is slidably installed on the fixed shaft. The telescopic plate is a telescopic structure, and a second spring is connected between one end of the telescopic plate and the inner wall of the mixing plate A. The second spring is electrically connected to the control system, and the second spring is located in the filter tank; when the second spring is energized, the second spring drives the telescopic plate to contract, so that the telescopic plate cannot block the filter tank and the filter membrane.

[0013] The cross bar, the first spring, the air sliding ring A and the mixing plate A form a filter unit. Multiple groups of the filter units are arranged on the transmission shaft. The multiple groups of the filter units are located above the two groups of partitions. A flow sensor is installed in the transmission shaft. The flow sensor is electrically connected to the control system. The flow sensor monitors the flow of the filtered wastewater.

[0014] The cam is located between the two groups of partitions, and a number of protrusions are arranged on the circumference of the cam. A ratchet tooth shape is arranged on the upper side of the middle part of the cam, and the lower side of the middle part of the cam is rotatably mounted on the transmission shaft through a bearing. An active disk is installed in the cam, and the active disk is installed on the transmission shaft. A pawl is rotatably mounted on the active disk through a torsion spring, and an electromagnet is installed on one side of the pawl. The electromagnet is a push-pull electromagnet, and the pawl abuts against the telescopic rod of the electromagnet. The electromagnet is electrically connected to the control system, and the pawl and the ratchet tooth shape are matched. When the electromagnet is energized, the telescopic rod of the electromagnet pushes the pawl to engage with the ratchet tooth shape, and the pawl compresses the torsion spring at the same time; when the electromagnet is not energized, the torsion spring is released, and the pawl is disengaged from the ratchet tooth shape under the action of the torsion spring.

[0015] The reciprocating plate is located outside the cam, a fixed plate is installed outside the reciprocating plate, the fixed plate is installed on the partitions on both sides, two sets of guide shafts are arranged on the fixed plate, the two sets of guide shafts pass through the reciprocating plate, the reciprocating plate slides on the guide shafts, and a spring is connected between the reciprocating plate and the fixed plate;

[0016] A flexible membrane is connected between the two ends of the reciprocating plate and the fixed plate. The reciprocating plate forms a sliding sealing connection with the two groups of partitions. A conveying chamber is formed between the reciprocating plate, the fixed plate, the two groups of partitions and the flexible membrane. The flexible membrane is made of elastic material. The partition on the upper side of the conveying chamber is connected with the outlet of the air slip ring B through a pipeline. The inlet of the air slip ring B is connected with the inside of the transmission shaft through a pipeline. The air slip ring B is installed on the partition on the upper side. The partition on the lower side of the conveying chamber is provided with a liquid outlet. After the cam enters the thrust stroke, it pushes the reciprocating plate to move outward and presses The spring is compressed, the volume of the delivery chamber is reduced, and the reciprocating plate delivers the waste water in the delivery chamber to the evaporation chamber; when the cam is away from the thrust stroke, the spring is released, and the spring pushes the reciprocating plate to move inward, the volume of the delivery chamber becomes larger, and the reciprocating plate draws the waste water above the two sets of partitions into the delivery chamber. Through the continuous rotation of the cam, the reciprocating plate continues to move outward and inward, and the waste water continues to enter and discharge the delivery chamber. Since the moving distance of the reciprocating plate is limited by the size of the cam, the volume change of the delivery chamber is certain, and quantitative delivery of waste water can be achieved.

[0017] The reciprocating plate, the fixed plate, the flexible membrane and the guide shaft form a conveying unit. The conveying unit is provided with multiple groups outside the cam. Solenoid valves are installed in the pipelines and liquid outlets connected by the partitions on both sides.

[0018] The fixing rods are provided in multiple groups, and the fixing rods are all installed on the transmission shaft. The mixing plate B is installed on the fixing rods, and the mixing plate B is provided with metal material;

[0019] An evaporation chamber is formed between the lower partition and the bottom of the cylinder, the evaporation chamber is communicated with the liquid outlet, and the fixing rod and the mixing plate B are located in the evaporation chamber.

The evaporation pipe is connected with the evaporation chamber. Another group of solenoid valves are installed on the liquid inlet pipe and the evaporation pipe respectively.

[0021] A control panel is installed on the cylinder, the control system is arranged in the control panel, and the drive motor is equipped with an encoder.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The mixing plate A can fully mix the wastewater with slaked lime and sodium carbonate, and the mixing effect is better. While the first spring drives the mixing plate A to move left and right, the spiral shaft in the mixing plate A slides along the spiral groove, so that the mixing plate A rotates while moving; the mixing plate A rotates while following the revolution of the crossbar, and the mixing plate A moves along the axial direction of the crossbar, so that the mixing range changes continuously, which can fully mix the wastewater in the sleeve with slaked lime and sodium carbonate, and accelerate the wastewater treatment efficiency.

[0024] 2. The mixing plate A and the filter membrane cooperate to achieve rapid filtration of wastewater, so that impurities are not easily deposited on the filter membrane. The conveying chamber extracts the softened wastewater through the filter membrane, filter tank, bellows and air slip ring A to the inside of the transmission shaft. At this time, the softened wastewater passes through the filter membrane and enters the filter tank. After passing through the filter tank, the wastewater is transported to the transmission shaft through the pipeline and air slip ring A. During the rotation and revolution of the filter membrane following the mixing plate A, the wastewater impacts the filter membrane, making it difficult for impurities to deposit on the surface of the filter membrane, ensuring that the filter membrane has a good filtering effect.

[0025] 3. The cam, reciprocating plate and flow sensor cooperate to realize the quantitative delivery of wastewater and improve the treatment efficiency. After the cam enters the push stroke, it pushes the reciprocating plate to move outward and compresses the spring, the volume of the delivery chamber decreases, and the reciprocating plate delivers the wastewater in the delivery chamber to the evaporation chamber; when the cam is away from the push stroke, the spring is released, and the spring pushes the reciprocating plate to move inward, the volume of the delivery chamber increases, and the reciprocating plate draws the wastewater above the two sets of partitions into the delivery chamber. Through the continuous rotation of the cam, the reciprocating plate continues to move outward and inward, and the wastewater continues to enter and discharge the delivery chamber. Since the moving distance of the reciprocating plate is limited by the size of the cam, the volume change of the delivery chamber is certain, which can realize the quantitative delivery of wastewater and improve the treatment efficiency of wastewater.

[0026] 4. After the wastewater is filtered, it is directly evaporated and cannot be transported again. The metal material in the mixing plate B is in the magnetic field of the coil. The drive motor drives the fixed rod to rotate through the transmission shaft, and the fixed rod drives the mixing plate B to rotate. The metal material in the mixing plate B cuts the magnetic flux lines and generates heat. The mixing plate B heats the softened wastewater to generate steam. The steam is transported through the evaporation pipe for further treatment. The impurities are discharged from the discharge pipe to achieve rapid separation and treatment of the wastewater concentrate. BRIEF DESCRIPTION OF THE DRAWINGS

An electromagnet 253 is installed on one side of the pawl 252. The electromagnet 253 is a push-pull electromagnet. The pawl 252 abuts against the telescopic rod of the electromagnet 253.

The flexible membrane 282 is made of elastic material. The partition 111 on the upper side of the conveying chamber 113 is connected to the outlet of the air slip ring B27 through a pipeline. The inlet of the air slip ring B27 is connected to the inside of the transmission shaft 21 through a pipeline. The air slip ring B27 is installed on the partition 111 on the upper side. The partition 111 on the lower side of the conveying chamber 113 is provided with a liquid outlet; after the cam 25 enters the thrust stroke, it pushes the reciprocating plate 28 to move outward and compresses the spring, the volume of the conveying chamber 113 is reduced, and the reciprocating plate 28 conveys the wastewater in the conveying chamber 113 to the evaporation chamber 114; when the cam 25 is away from the thrust stroke, the spring is Release, the spring pushes the reciprocating plate 28 to move inward, the volume of the delivery chamber 113 increases, the reciprocating plate 28 draws the wastewater above the two groups of partitions 111 into the delivery chamber 113, and the cam 25 continues to rotate, the reciprocating plate 28 continues to move outward and inward, and the wastewater continues to enter and discharge the delivery chamber 113. Since the moving distance of the reciprocating plate 28 is limited by the size of the cam 25, the volume change of the delivery chamber 113 is certain, and the quantitative delivery of wastewater can be achieved; the reciprocating plate 28, the fixed plate 241, the flexible membrane 282 and the guide shaft 281 form a delivery unit, and multiple groups of delivery units are arranged on the outside of the cam 25, and electromagnetic valves are installed in the pipes connected to the partitions 111 on both sides and the liquid outlet.

[0044] There are multiple groups of fixed rods 221, and the multiple groups of fixed rods 221 are all installed on the transmission shaft 21. The mixing plate B231 is installed on the fixed rods 221, and metal material is arranged inside the mixing plate B231; an evaporation chamber 114 is formed between the lower partition 111 and the bottom of the cylinder 11, and the evaporation chamber 114 is connected to the liquid outlet, and the fixed rods 221 and the mixing plate B231 are located in the evaporation chamber 114.

[0045] Working principle: Press the start button on the control panel 1, the device starts, the staff puts wastewater into the liquid inlet pipe 12, and puts in the corresponding slaked lime and sodium carbonate in turn, the control system drives the transmission shaft 21 to rotate through the driving motor 2, the transmission shaft 21 drives the cross bar 22 and the fixed rod 221 to revolve, the cross bar 22 drives the mixing plate A23 to revolve, the mixing plate A23 mixes the slaked lime and sodium carbonate with the wastewater, so that the magnesium ions and calcium ions in the wastewater react to generate magnesium hydroxide and calcium carbonate precipitation respectively, thereby reducing the hardness of the wastewater and softening the wastewater; the fixed rod 221 drives the mixing plate B231 to rotate, at this time, the mixing plate B231 is idling.

[0046] When the mixing plate A23 mixes wastewater with slaked lime and sodium carbonate, the control system continuously powers on and off the first spring 24 for a time T. The time T is set in advance by the staff through the control system. After the first spring 24 is powered on, each turn of the first spring 24 generates a mutually attractive magnetic field, which causes the first spring 24 to contract, and the first spring 24 pulls the sealing plate 262 on the right to move right. While the sealing plate 262 on the right pulls the mixing plate A23 to move right, the spiral shaft 261 in the mixing plate A23 slides along the spiral groove 223, causing the mixing plate A23 to rotate while moving right;

[0047] When the first spring 24 is powered off by the control system, the first spring 24 gradually becomes longer under the action of its own elastic force, and the first spring 24 pushes the sealing plate 262 on the right to move left. While the sealing plate 262 on the right drives the mixing plate A23 to move left, the spiral shaft 261 in the mixing plate A23 slides in the opposite direction along the spiral groove 223, so that the mixing plate A23 moves to the left and rotates in the opposite direction at the same time; the mixing plate A23 rotates while following the revolution of the cross bar 22, and the mixing plate A23 moves axially along the cross bar 22, so that the mixing range changes continuously, and the wastewater in the sleeve 112 can be fully mixed with slaked lime and sodium carbonate, thereby accelerating the wastewater treatment efficiency.

[0048] After the wastewater is softened and mixed for a set time, it will be transported and filtered. The staff will energize the second spring 264 through the control system. Each turn of the second spring 264 generates a mutually attractive magnetic field, which causes the second spring 264 to contract. The second spring 264 pulls the telescopic plate 263 to gradually contract, so that the telescopic plate 263 cannot block the filter tank and the filter membrane 26.

[0049] When the second spring 264 is energized, the control system energizes the electromagnet 253, and the telescopic rod on the electromagnet 253 pushes the pawl 252 out to engage with the ratchet teeth on the cam 25. The driving motor 2 drives the active disk 251 to rotate through the transmission shaft 21, and the active disk 251 drives the cam 25 to rotate through the pawl 252 and the ratchet teeth.

[0050] When the protrusion on one side of the cam 25 approaches the reciprocating plate 28 (the cam 25 enters the push stroke), the encoder inside the driving motor 2 feeds back data to the control system, and the control system opens the solenoid valve in the liquid outlet and the solenoid valve in the evaporation tube 121. The protrusion on the cam 25 pushes the reciprocating plate 28 to slide outward on the guide shaft 281, and the reciprocating plate 28 compresses the spring at the same time, and the reciprocating plate 28 discharges the air in the conveying chamber 113 to the outside air through the liquid outlet and the evaporation tube 121;

[0051] When the protrusion on one side of the cam 25 is away from the reciprocating plate 28 (the cam 25 is away from the push stroke), the encoder in the drive motor 2 feeds back data to the control system, and the control system opens the solenoid valve in the connecting pipe between the conveying chamber 113 and the air slip ring B27, and the spring connected to the reciprocating plate 28 is released. The spring pushes the reciprocating plate 28 to move inward, and the volume of the conveying chamber 113 increases. The conveying chamber 113 extracts the softened wastewater through the filter membrane 26, the filter tank, the bellows 222 and the air slip ring A232 to the inside of the transmission shaft 21. At this time, the softened wastewater The wastewater passes through the filter membrane 26 and enters the filter tank. After passing through the filter tank, the wastewater is transported to the transmission shaft 21 through the pipeline and the air slip ring A232. During the rotation and revolution of the filter membrane 26 following the mixing plate A23, the wastewater impacts the filter membrane 26, so that impurities are not easily deposited on the surface of the filter membrane 26, ensuring that the filter membrane 26 has a good filtering effect. After that, the wastewater is detected by the flow sensor in the transmission shaft 21, and then flows downward from the inside of the transmission shaft 21. Finally, the wastewater is extracted to the conveying chamber 113 through the transmission shaft 21, the pipeline and the air slip ring B27.

[0052] When the protrusion on one side of the cam 25 approaches the reciprocating plate 28, the control system opens the solenoid valve in the liquid outlet and closes the solenoid valve in the connecting pipe between the air slip ring B27. The cam 25 pushes the reciprocating plate 28 to move outward, and the reciprocating plate 28 transports the softened wastewater in the conveying chamber 113 to the evaporation chamber 114 through the liquid outlet.

[0053] When the flow sensor in the transmission shaft 21 detects the entry of wastewater, the control system connects the coil 13 to the circuit, and a magnetic field is generated at both ends of the coil 13. The metal material in the mixing plate B231 is in the magnetic field of the coil 13. The driving motor 2 drives the fixed rod 221 to rotate through the transmission shaft 21, and the fixed rod 221 drives the mixing plate B231 to rotate. The metal material in the mixing plate B231 generates heat while cutting the magnetic lines of force.
