One end of the push rod motor 14 is fixedly connected to the sliding seat 15. The top of the sliding seat 15 close to the push rod motor 14 is fixedly connected to a positioning member 22. The positioning member 22 is arranged in a semicircular shape. Both ends of the positioning member 22 are hinged with clamping members 23. The two clamping members 23 are arranged The arrangement is arc-shaped, and the two clamping members 23 are symmetrically arranged. The same material receiving tank 18 is clamped between the inner walls of the positioning member 22 and the two clamping members 23.

A bayonet 34 is fixedly connected to the bottom of the plug rod 33. Both sides of the bottom of the bayonet 34 are arranged as inclined surfaces. A positioning groove 37 is provided at the top of the base 3. The inner walls on both sides of the positioning groove 37 are adapted to the inclined surfaces on both sides of the bottom of the bayonet 34. The tops of both sides of the positioning groove 37 are fixedly connected with fixing sleeves 38. The sides of the two fixing sleeves 38 that are close to each other are fixedly connected with conductive contacts 39. The two conductive contacts 39 are respectively attached to both sides of the bayonet 34, and the material of the bayonet 34 is conductive material.

[0023] In the present invention, a pressing plate 29 is fixedly connected to the middle of the two clamping members 23 on the side away from each other, and two symmetrically distributed baffles 25 are fixedly connected to the top of the sliding seat 15. The same first spring 24 is fixedly connected between the pressing plate 29 and the baffle 25 on the same side of the top of the sliding seat 15. The two first springs 24 are both in a compressed state, pushing the clamping members 23 to close to the outer wall of the material receiving tank 18, clamping the material receiving tank 18, so that the material receiving tank 18 is firmly fixed on the top of the sliding seat 15. When installing the material receiving tank 18, push the material receiving tank 18 between the two clamping members 23, and the ends of the two clamping members 23 that are close to each other are firstly subjected to the pressure of the outer wall of the bottom of the material receiving tank 18 and are After the material receiving tank 18 is stretched open, the first spring 24 is further compressed by the pressing plate 29 and the baffle plate 25. When the material receiving tank 18 is fitted with the inner wall of the positioning member 22, the first spring 24 pushes the clamping member 23 through the pressing plate 29 to press the material receiving tank 18. The operation of removing the material receiving tank 18 is opposite to the step of installing the material receiving tank 18. The material receiving tank 18 is pulled in the direction away from the positioning member 22, and the two clamping members 23 are first stretched open, and the first spring 24 is further compressed. After the material receiving tank 18 is completely detached, the first spring 24 pushes the clamping member 23 to automatically reset again, so that the clamping process of the material receiving tank 18 and the resetting process of the clamping member 23 are automatically completed during the movement of the material receiving tank 18 without the need for additional operation.

[0024] In the present invention, one end of the two clamping members 23 away from the positioning member 22 is configured as an arc surface, which can prevent the outer wall of the material receiving tank 18 from being scratched and reduce the wear between the material receiving tank 18 and the clamping members 23.

When the push rod motor 14 drives the sliding seat 15 to move, the damping member 27 is shaken inside the material receiving tank 18 due to inertia, offsetting part of the kinetic energy of the material receiving tank 18 during the movement process, and preventing the acid from splashing out of the material receiving tank 18 after being bumped.

[0028] In the present invention, the top of the base 3 near the guide rail 16 is fixedly connected to the limit block 17, the side of the limit block 17 near the sliding seat 15 is set to be adapted to the slope of the bayonet 34, the middle of the slope of the limit block 17 is embedded with a permanent magnet 28, the middle of the inclined surface of the bayonet 34 near the limit block 17 is embedded with an iron sheet 35, and the bottom of the bayonet 34 is rotatably connected to the roller 36. When the material collecting tank 18 needs to be removed from the top of the sliding seat 15, the push rod motor 14 can be controlled to slide The seat 15 is further pushed out in the direction close to the limit block 17, and the pin 34 is disengaged from the positioning groove 37 and moves along the top of the base 3 until the inclined surface of the pin 34 fits the slope of the limit block 17, and the travel of the sliding seat 15 is limited by the limit block 17. After the pin 34 contacts the limit block 17, the permanent magnet 28 absorbs the iron sheet 35 to further enhance the stability of the limit, and the roller 36 converts the sliding friction on the bottom of the pin 34 into rolling friction, thereby reducing the loss of the pin 34.

[0029] In the present invention, one end of the two guide rails 16 close to the push rod motor 14 is fixedly connected to the same fixing plate 21, and the middle position of the top of the fixing plate 21 is fixedly connected to a limiting hoop 20, which is clamped on the outer wall of the push rod motor 14. The push rod motor 14 is further reinforced by the limiting hoop 20 and the fixing plate 21.

[0030] In the present invention, the outer wall of the reactor body 1 is fixedly connected to the shell 4, the outer walls on both sides of the shell 4 are fixedly connected to the handles 5, the outer wall of the shell 4 is fixedly connected to the controller 11, and the shell 4 and the reactor body 1 are filled with a heat insulation layer 43, and the inner wall of the heat insulation layer 43 is provided with heating grooves 44 distributed at equal distances, and the interior of the heating grooves 44 is fixedly connected to the resistance heater 42, the resistance heater 42 can provide a high temperature environment for the reaction in the reactor body 1, so as to accelerate the reaction rate, the heat insulation layer 43 is used for heat preservation, the shell 4 plays a protective role, and the device can be carried by the handle 5, and the controller 11 is connected to the electrical appliances in the device through a signal line, so as to facilitate centralized control.

[0031] In the present invention, a sealing cover 6 is clamped on the top of the reactor body 1, a feed hopper 7 is inserted in the middle of the sealing cover 6, a first solenoid valve 8 is arranged at the middle channel of the feed hopper 7, an air inlet 9 is inserted on one side of the sealing cover 6, and an exhaust port 10 is inserted on the other side of the sealing cover 6. The sealing cover 6 is used to close the top space of the reactor body 1. After the first solenoid valve 8 is controlled to conduct the feed hopper 7, the acid solution and the treatment agent enter the reactor body 1 through the feed hopper 7. The air inlet 9 is connected to the airflow supply pipeline to introduce airflow into the interior of the reactor body 1. The exhaust port 10 is connected to the steam collection device to collect the steam taken away from the interior of the reactor body 1 by the airflow.

[0032] When in use, the two conductive contacts 39 are respectively connected to the two poles of the power supply circuit of the second solenoid valve 12. Before adding waste acid liquid and treatment agent into the reactor body 1, the push rod motor 14 is controlled to pull the sliding seat 15 backward, and the slider 31 slides along the guide rail 16. The bottom inclined surface of the latch 34 slides relative to the inner wall of the positioning groove 37. The latch 34 receives upward pressure in this process, and further compresses the second spring 40 upward through the insertion rod 33 and the piston 41 until the latch 34 disengages from the positioning groove 37 and moves along the top of the base 3. After the reaction is completed, the push rod motor 14 is controlled to push forward until the latch 34 reaches above the positioning groove 37, and the material receiving tank 18 reaches the nozzle of the discharge pipe 13 synchronously. Directly below, the second spring 40 in the compressed state inside the spring tube 32 is reset, and the pin 34 is pushed into the positioning groove 37 again through the insertion rod 33. At this time, the pin 34 made of conductive material contacts two conductive contacts 39 at the same time, connecting the power circuit of the second solenoid valve 12, and the discharge pipe 13 is connected and discharges the treated acid. This process ensures that the second solenoid valve 12 will be turned on only when the receiving tank 18 is below the pipe mouth of the discharge pipe 13, ensuring that the discharged acid can be received, preventing the acid from not being collected in time and flowing to the outside, and after the pin 34 reaches the positioning groove 37, the power circuit of the second solenoid valve 12 is automatically connected, without the need for additional control steps, and the operation process is simple.
