When the sample and the solution are mixed, the control system connects the two semiconductors on the thermocouple plate A and the thermocouple plate B to the circuit. Since the thermocouple plate A is located on the sleeve and the thermocouple plate B is located on the cylinder, and the two semiconductors and the metal plate on the thermocouple plate A are the hot ends of the Seebeck effect, and the two semiconductors and the metal plate on the thermocouple plate B are the cold ends of the Seebeck effect, the temperature of the hot end is higher than that of the cold end.

[0019] A control panel is provided on the cylinder, and the control system is provided in the control panel.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The sample and solution are mixed more evenly by cooperating with mixing plates A and B. The control system first energizes the telescopic spring. Each turn of the telescopic spring generates a mutually attractive magnetic field. This magnetic field compresses the telescopic spring, causing it to pull the follower plate toward the vertical axis. While the follower plate pulls mixing plate A toward the vertical axis, the positioning shaft in mixing plate A slides along the spiral groove, causing mixing plate A to rotate while moving. The reset spring pushes mixing plate B toward the vertical axis. The positioning shaft in mixing plate B slides in the wave groove, causing mixing plate B to rotate back and forth on the horizontal axis, causing mixing plate B to vibrate back and forth. The rotation and revolution of mixing plate A and the reciprocating vibration of mixing plate B are used to mix the sample and solution, achieving forced mixing of the sample and solution, thereby improving the mixing effect and making the sample and solution mix more evenly.

[0022] 2. After mixing, clean the equipment for subsequent use. The vacuum pump pressurizes the external water source and delivers it to the interior of the vertical shaft through the pipe and the air slip ring. Since the solenoid valve in the connecting pipe is closed, the water flows through the vertical shaft into several horizontal shafts and into the cleaning plate through the pipe. As the water pressure in the horizontal shaft gradually increases, the one-way valves in the water spray ports on the horizontal shaft and the cleaning plate open, and water is sprayed onto the inner wall of the sleeve and the partition through the water spray ports on the horizontal shaft and the cleaning plate. The sleeve and the partition are cleaned by the impact of the water flow. The cleaned waste water is discharged from the equipment through the pipe and the discharge port, completing the cleaning of the equipment for subsequent use.

[0023] 3. Recover heat after mixing to reduce equipment energy consumption. The control system connects the two semiconductors on thermocouple plates A and B to the circuit. Since thermocouple plate A is located on the sleeve and thermocouple plate B is located on the cylinder, and the two semiconductors and metal plate on thermocouple plate A are the hot end of the Seebeck effect, and the two semiconductors and metal plate on thermocouple plate B are the cold end of the Seebeck effect, the hot end temperature is higher than the cold end. The hot and cold ends generate current through the Seebeck effect and transmit it to the control system to realize waste heat recovery after mixing and reduce equipment energy consumption.

The filter plate 4 is provided on the cylinder 11, and a screen is provided on the filter plate 4.

[0038] A connecting pipe 116 is provided in the middle of the partition 114, and the connecting pipe 116 is connected to the inside of the vertical shaft 21. A discharge port 115 is provided on the cylinder 11, and one side of the partition 114 is connected to the discharge port 115 through a pipe passing through the sleeve 111; solenoid valves are installed in the liquid inlet pipe 112, the liquid outlet pipe 113, the discharge port 115, the pipe connected to the mixing plate B24 (not shown in the figure) and the connecting pipe 116, and the liquid inlet pipe 112 and the liquid outlet pipe 113 are also connected in series with a flow meter. Multiple groups of temperature sensors are provided in the sleeve 111, and the temperature sensors, solenoid valves and flow meters are all electrically connected to the control system.

[0039] Several temperature difference plates A117 are embedded in the inner wall of the sleeve 111, and several temperature difference plates B118 are embedded in the outer side of the cylinder 11. The temperature difference plates A117 and B118 correspond to each other one by one. Metal plates and two groups of semiconductors of different materials are provided on the temperature difference plates A117 and B118. One end of the two semiconductors of different materials is connected to the metal plate. The two semiconductors on the temperature difference plate A117 and the two semiconductors on the temperature difference plate B118 are connected by wires, one of which is connected to the control system. When the sample and the solution are mixed, The control system connects the two semiconductors on the thermocouple plate A117 and the thermocouple plate B118 to the circuit. Since the thermocouple plate A117 is located on the sleeve 111, and the thermocouple plate B118 is located on the cylinder 11, and the two semiconductors and the metal plate on the thermocouple plate A117 are the hot end of the Seebeck effect, and the two semiconductors and the metal plate on the thermocouple plate B118 are the cold end of the Seebeck effect, the temperature of the hot end is higher than that of the cold end. The hot end and the cold end generate current through the Seebeck effect and transmit it to the control system to realize the recovery of waste heat after mixing and reduce the energy consumption of the equipment.

[0040] Working principle: Press the start button on the control panel 1 to start the equipment. The control system controls the solenoid valve in the liquid inlet pipe 112 to open. The staff transports the sample and solution into the cylinder 11 respectively through the liquid supply system and the liquid inlet pipe 112. The flow meter in the liquid inlet pipe 112 monitors the flow changes of the sample and solution in real time. The control system drives the vertical shaft 21 to rotate through the drive motor 2. The vertical shaft 21 drives several horizontal shafts 22 to revolve. The several horizontal shafts 22 drive the mixing plate A23, mixing plate B24 and cleaning plate 3 to revolve. The mixing plate A23, mixing plate B24 and cleaning plate 3 are used to mix the sample and solution.

[0041] When the mixing plate A23 mixes the sample and the solution, the control system first energizes the telescopic spring 233. Each turn of the telescopic spring 233 generates a magnetic field that attracts each other. The magnetic field compresses the telescopic spring 233, causing the telescopic spring 233 to pull the follower plate 232 to move toward the side of the vertical axis 21. While the follower plate 232 pulls the mixing plate A23 to move toward the side of the vertical axis 21, the positioning shaft 231 in the mixing plate A23 slides along the spiral groove 222, causing the mixing plate A23 to rotate while moving. It should be noted that the telescopic spring 233 in the present application is electrically connected to the control system through a wire and an electric slip ring, which belongs to the prior art. The wire connected to the telescopic spring 233 is buried in the horizontal axis 22 and the vertical axis 21, so that the telescopic spring 233 can be energized and de-energized during the rotation process.

[0042] When the mixing plate A23 moves toward the side of the vertical axis 21, the return spring between the mixing plate B24 and the horizontal axis 22 is released, and the return spring pushes the mixing plate B24 to move toward the side of the vertical axis 21. The positioning shaft 231 in the mixing plate B24 slides in the wave groove 223, causing the mixing plate B24 to rotate back and forth on the horizontal axis 22, causing the mixing plate B24 to vibrate back and forth; through the rotation and revolution of the mixing plate A23 and the reciprocating vibration of the mixing plate B24, the sample and the solution are mixed, and forced mixing of the sample and the solution is achieved to improve the mixing effect.

[0043] When the telescopic spring 233 is energized for a set time, the control system de-energizes the telescopic spring 233 and activates the electric cylinders 14 on both sides. The control system calculates the height of the sample and the solution in the sleeve 111 based on the data of the flow meter in the liquid inlet pipe 112. The control system adjusts the electric cylinders 14 on both sides to drive the contact rings 13 to move according to the height of the sample and the solution, so that the distance between the contact rings 13 on both sides is greater than the height of the sample and the solution. After that, the control system connects the contact rings 13 on both sides to the circuit. The current enters from the contact ring 13 on one side, flows through the effective number of turns of the coil 12, and then flows out from the contact ring 13 on the other side to the control system. The effective number of turns of the coil 12 refers to the number of turns between the contact rings 13 on both sides.

[0044] When the coil 12 is energized, a magnetic field is generated. When the telescopic spring 233 is de-energized, the telescopic spring 233 gradually lengthens under the action of its own elastic force, and the telescopic spring 233 pushes the following plate 232 to move toward the side away from the vertical axis 21 (i.e., toward the side of the mixing plate B24). While the following plate 232 pushes the mixing plate A23 to move, the positioning shaft 231 in the mixing plate A23 slides in the opposite direction along the spiral groove 222, causing the mixing plate A23 to rotate in the opposite direction. The mixing plate A23 rotates while revolving, so that the sample and the solution are fully mixed; thereafter, the mixing plate A23 pushes the mixing plate B24 to move toward the side away from the vertical axis 21 through the ball bearing, and the positioning shaft 231 in the mixing plate B24 slides in the wave groove 223, causing the mixing plate B24 to vibrate continuously on the horizontal axis 22.

[0045] When the mixing plate A23 revolves and rotates, the mixing plate A23 drives the extension plates 25 on both sides to follow the rotation and revolution. The metal material inside the extension plate 25 cuts the magnetic flux lines in the magnetic field of the coil 12. The metal material heats up and transfers the heat to the heat-conducting medium and the mixing plate A23. The heat-conducting medium expands after absorbing the heat, and the heat-conducting medium pushes the extension plate 25 to move outward from the sliding groove in the mixing plate A23. The sample and solution are heated by the mixing plate A23 and the extension plate 25. The mixing plate A23 and the extension plate 25 mix the sample and solution at the same time and heat them, so that the sample and solution are fully mixed and heated evenly.

[0046] During the mixing process of the sample and solution, the solenoid valve in the pipe connected to the mixing plate B24 is in a closed state. The sample and solution in the mixing process cannot enter the horizontal axis 22 through the pipe connected to the mixing plate B24, preventing the solution and sample from entering the horizontal axis 22 during the mixing process.

[0047] When the sample and solution are mixed for the set time, the sample and solution are evenly mixed, and the control system opens the solenoid valves in the liquid outlet pipe 113, the connecting pipe 116 and the connecting pipe of the mixing plate B24. The liquid outlet pipe 113 and the drainage system cooperate to extract the mixed sample and solution outward. The mixed sample and solution pass through the filter mesh on the mixing plate B24 and enter the filter chamber. They are transported to the inside of the horizontal axis 22 through the pipe connecting the filter chamber and the mixing plate B24, and then transported to the vertical axis 21 through the inside of the horizontal axis 22. Finally, they are transported to the upper side of the filter plate 4 through the vertical axis 21 and the connecting pipe 116. After the mixed sample and solution pass through the screen on the filter plate 4, they are discharged from the liquid outlet pipe 113 to the drainage system, and the mixing plate B24 drives the filter mesh to vibrate, which can prevent impurities from clogging the filter mesh, so that the sample and solution can pass through the filter mesh.

[0048] When the required sample and solution are discharged from the liquid outlet pipe 113, a certain amount of impurities and unwanted mixtures will be deposited on the upper side of the partition 114. The mixing device will clean the cylinder 11. The control system will close the electromagnetic valve in the pipeline connected to the liquid inlet pipe 112, the liquid outlet pipe 113, the mixing plate B24 and the connecting pipe 116, and control the electromagnetic valve in the discharge port 115 to open and the vacuum pump to work. The vacuum pump pressurizes the external water source and transports it to the inside of the vertical shaft 21 through the pipeline and the air slip ring. Due to the inside of the connecting pipe 116, the water in the connecting pipe 116 is The solenoid valve is closed, so water flows through the vertical axis 21 into several horizontal axes 22 and into the cleaning plate 3 through the pipe. As the water pressure in the horizontal axis 22 gradually increases, the one-way valves in the water nozzles on the horizontal axis 22 and the cleaning plate 3 are opened, and water is sprayed onto the inner wall of the sleeve 111 and the partition 114 through the water nozzles on the horizontal axis 22 and the cleaning plate 3. The sleeve 111 and the partition 114 are cleaned by the impact of water flow. The cleaned waste water and impurities are discharged from the equipment through the pipe and the discharge port 115, thereby achieving the cleaning treatment of the equipment.
