[0003] General solvent mixing equipment used in petroleum asphalt production cannot accurately control the temperature of asphalt when mixing asphalt. When the temperature of asphalt is low, the asphalt will become viscous or even solidify, which will easily lead to insufficient mixing of asphalt with other solvents and reduce the quality of asphalt mixed solvent.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. When the temperature of the asphalt in the mixing body is about to fall below the set range value, the heating pipe will heat the asphalt through the heating plate to increase the temperature of the asphalt. When the temperature of the asphalt is about to rise above the set range value, the heating pipe will stop working and then the asphalt will stop heating up. This will keep the temperature of the asphalt at a suitable level for stirring and mixing, making it easier to mix and better improving the quality of the asphalt.

[0017] 2. When the temperature of the asphalt is about to be higher than the set range value, the low-power power board will shrink, and then the heating tube will stop working, and then the temperature of the asphalt will drop. When the temperature of the asphalt is about to be lower than the set range value, the low-power power board will extend, and then the circuit of the low-power power board will be connected, so that the heating tube uses the heating plate to heat the asphalt. This can prevent the heating tube from working when the temperature of the asphalt just drops a little, which can improve the mixing quality of the asphalt and enhance the use effect of the asphalt.

[0018] 3. When use is finished, the motor can be operated, and then the cleaning device can be used to clean the inner wall of the mixing body. This can prevent the asphalt from sticking to the inner wall of the mixing body and solidifying on the mixing body. The asphalt on the inner wall of the mixing body can be cleaned, so that the next mixing and stirring can be better carried out.

[0019] 4. When there is too much asphalt inside the mixing body, the blocking block will block the circuit of the two second power boards, and then the cleaning device will not clean. When there is less asphalt inside the mixing body, the motor will work, and then the annular lifting plate will drive the cleaning device to clean. In this way, it can automatically determine whether it is appropriate to clean the inner wall of the mixing body.

[0020] 5. When the two second power boards are disconnected, the electric push rod will not work, and then continue to seal the reciprocating screw to prevent asphalt from being stained on the reciprocating screw. If asphalt is stained on the reciprocating screw, it will affect the lifting and lowering of the annular lifting plate, which can increase the service life of the reciprocating screw.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] See also Figures 1 to 8 The present invention provides a solvent mixing device for petroleum asphalt production, and the technical solution is as follows: A solvent mixing device for producing petroleum asphalt, comprising a mixing body 1, a power source is fixedly installed inside the mixing body 1, a heating plate 2 with a plate-like structure is installed on the inner wall of the mixing body 1, a plurality of heating tubes 3 are evenly installed inside the heating plate 2, a detection mechanism for controlling the opening and closing of the heating tubes 3 is fixedly installed inside the mixing body 1, a stirring blade 5 is rotatably installed inside the mixing body 1, a driving motor 4 for driving the stirring blade 5 to rotate is fixedly installed on the upper end of the mixing body 1, and the driving motor 4 is electrically connected to the power source; Detection mechanism: The detection mechanism can control the temperature of the asphalt inside the mixing body 1 to be within the set range by controlling the working state of the heating pipe 3.

[0027] When the device is started, the temperature of the asphalt inside the mixing body 1 is low, and then the detection mechanism will control the heating tube 3 to heat the asphalt inside the mixing body 1. When it is heated to a suitable temperature, the driving motor 4 drives the stirring blade 5 to stir the internal asphalt. Then the detection mechanism controls the heating tube 3 to keep the temperature of the asphalt inside the mixing body 1 at a temperature suitable for stirring and mixing. In this way, the asphalt can be stirred better, the asphalt can be mixed more fully with other solvents, and the quality of the asphalt after the solvents are mixed can be improved.

[0028] As an embodiment of the present invention, refer to Figure 5 and Figure 6 The detection mechanism includes a detection shell 9 fixedly installed inside the heating plate 2, a detection groove and a connecting groove are opened inside the detection shell 9, and the connecting groove is located on the upper side of the detection groove, a temperature sensing medium 10 is placed inside the detection groove, a sliding plug 11 is slidably installed on the upper end of the temperature sensing medium 10, a first push rod 12 is fixedly installed on the upper end of the sliding plug 11, and the first push rod 12 extends into the connecting groove, a lifting plate 15 is slidably installed in the connecting groove, and the lifting plate 15 is fixedly connected to the first push rod 12, a first conductive plate 16 is fixedly installed inside the lifting plate 15, two high-power power boards 13 and two low-power power boards 14 that cooperate with the first conductive plate 16 are fixedly installed inside the detection shell 9, and the two high-power power boards 13 and the two low-power power boards 14 are electrically connected to the power supply, a spring is fixedly installed between the lifting plate 15 and the inner wall of the connecting groove, and a contraction component for controlling the extension and contraction of the low-power power board 14 is fixedly installed inside the detection shell 9.

[0029] When the temperature of the asphalt inside the mixing body 1 is low, the first conductive plate 16 will connect the circuits of the two high-power connecting plates 13, and then the heating tube 3 will quickly heat the asphalt inside the mixing body 1. The rising temperature of the asphalt inside the mixing body 1 can expand the temperature-sensitive medium 10, and then push the sliding plug 11 to move away from the temperature-sensitive medium 10. The movement of the temperature-sensitive medium 10 can push the first push rod 12 to move, and the movement of the first push rod 12 can push the lifting plate 15 to move away from the first push rod 12. When the temperature of the asphalt reaches the set range, the circuits of the two high-power connecting plates 13 will be disconnected, and the circuits of the two low-power connecting plates 14 will be connected, and then the mixing body 1 will be heated. The temperature of the asphalt inside the main body 1 rises slowly. When the temperature of the asphalt inside the mixed main body 1 is about to exceed the set range value, the two low-power power boards 14 will be disconnected to stop the heating pipe 3 from working, and then the temperature of the asphalt will decrease. When the temperature of the asphalt is about to be lower than the set range value, the low-power power board 14 will be connected, and then the temperature of the asphalt will continue to increase, so that the asphalt always changes within the set range value. In this way, one of the temperatures of the asphalt can be within the set range value, which can prevent the asphalt from becoming viscous due to low temperature and prevent the asphalt from being insufficiently mixed with other solvents. In this way, the quality of the mixed asphalt can be improved. Too high or too low temperature will affect the mixing quality of the asphalt, which is an extended beneficial effect.

[0030] The temperature sensing medium 10 can be gaseous or liquid, and there is no need to clearly indicate it here. As long as it meets the requirements of use, it can be used, such as mercury, alcohol and kerosene, etc., and there are no marked detection grooves and connection grooves inside it, just simple grooves, and no marking is required. High power and low power are existing technologies, and there are many ways to control them, and full protection is not required.

[0031] As an embodiment of the present invention, refer to Figure 6The contraction component includes a contraction groove 17 opened in the detection housing 9, a contraction plate 52 is slidably installed inside the contraction groove 17, and the contraction plate 52 is fixedly connected to the low-power power connection board 14. A first cavity 18 is opened inside the detection housing 9, and the first cavity 18 is located on the upper side of the contraction groove 17. A first piston 19 is slidably installed inside the first cavity 18, and a first trapezoidal column 20 is fixedly installed on one side of the first piston 19, and the first trapezoidal column 20 extends into the connecting groove, and a pipeline is connected between the first cavity 18 and the contraction groove 17. A second cavity 21 is opened inside the detection housing 9, and the second cavity 21 is located on the lower side of the contraction groove 17. A second piston 22 is slidably installed inside the second cavity 21, and a second trapezoidal column 23 is fixedly installed on one side of the second piston 22, and the second trapezoidal column 23 extends into the connecting groove, and a pipeline is connected between the second cavity 21 and the contraction groove 17. A leak port is opened at the top of the connecting groove and the outside.

[0032] When the lifting plate 15 moves to the top of the connecting groove, it will push the first trapezoidal column 20 to move away from the lifting plate 15. The movement of the first trapezoidal column 20 can push the first piston 19 to move, and then the first piston 19 pushes the gas in the first cavity 18 into the contraction groove 17. Then the gas inside the contraction groove 17 will push the contraction plate 52 to move away from the lifting plate 15. The movement of the contraction plate 52 can drive the low-power power board 14 to move, and at the same time, it will push the contraction plate 52 away from the gas on the side of the low-power power board 14 to move into the second cavity 21, and then push the second piston 22 to move in the direction close to the lifting plate 15. The movement of the first piston 19 can make the second trapezoidal column 23 extend. When the lifting plate 15 moves to the position of the second trapezoidal column 23, it will push the second trapezoidal column 23 to move away from the lifting plate 15, and then push the gas in the second cavity 21 to When the shrinkage groove 17 moves, the gas in the shrinkage groove 17 will push the shrinkage plate 52 and the low-power power board 14 to move toward the lifting plate 15, and then the first conductive plate 16 is used to connect the circuits of the two low-power power boards 14. When the shrinkage plate 52 moves toward the lifting plate 15, the gas on the side of the shrinkage plate 52 close to the lifting plate 15 can be pushed into the first cavity 18, and then the gas in the first cavity 18 will push the first piston 19 and the first trapezoidal column 20 to move toward the lifting plate 15, and then the first trapezoidal column 20 is extended. In this way, when the temperature of the asphalt inside the mixing body 1 is about to be lower than the set range, the heating pipe 3 can be timely used to heat the asphalt. When the temperature inside the mixing body 1 is about to be higher than the set range, the heating pipe 3 can be timely stopped from heating to prevent the asphalt temperature from being too high and accelerate the aging speed of the asphalt, so that the asphalt can be stirred more fully.

[0033] As an embodiment of the present invention, refer to Figure 8 A mounting groove is provided inside the mixing body 1, and a reciprocating screw rod 7 is rotatably installed inside the mounting groove. A motor 6 for driving the reciprocating screw rod 7 to rotate is installed at the upper end of the mixing body 1. An annular placement groove is provided at the top of the mixing body 1, and an annular lifting plate 8 is slidably installed inside the annular placement groove, and the annular lifting plate 8 extends into the mounting groove and is installed on the reciprocating screw rod 7. A cleaning device 49 is fixedly installed at the lower end of the annular lifting plate 8, and the cleaning device 49 is close to the inner wall of the mixing body 1, and an opening and closing mechanism for controlling the opening and closing of the motor 6 is fixedly installed inside the mixing body 1.

[0034] Please see the position of the annular placement groove clearly. The annular placement groove is located around and is used to place the annular lifting plate 8. When the motor 6 is working, it will drive the reciprocating screw 7 to rotate. The annular lifting plate 8 can be lifted and lowered by the rotation of the reciprocating screw 7. The cleaning device 49 is fixedly installed on the annular lifting plate 8. When the annular lifting plate 49 moves, why can't the cleaning device 49 be driven to move? The lifting and lowering of the annular lifting plate 8 can drive the cleaning device 49 to be lifted and lowered. The inner wall of the mixing body 1 is cleaned by the lifting and lowering of the cleaning device 49, so that the asphalt on the inner wall of the mixing body 1 can be cleaned in time to prevent the asphalt from solidifying on the inner wall and affecting the quality of the next asphalt. In this way, the next mixing of asphalt and solvent can be better carried out. The two annular lifting plates 8 are one, and it is explained above that the annular lifting plate extends into the mounting groove and is threadedly installed on the reciprocating screw 7.

[0035] As an embodiment of the present invention, refer to Figure 8 The opening and closing mechanism includes a control shell 42 fixedly installed inside the mixing body 1, a second insulating plate 43 is slidably installed inside the control shell 42, a third conductive plate 44 is fixedly installed inside the second insulating plate 43, two third power connection plates 46 that cooperate with the third conductive plate 44 are fixedly installed inside the control shell 42, and the two third power connection plates 46 are electrically connected to the power supply and the motor 6 respectively, a buffer plate 47 is slidably installed inside the control shell 42, and the buffer plate 47 is closer to the annular lifting plate 8, two power-on springs 45 are fixedly and symmetrically installed between the control shell 42 and the buffer plate 47, and the power-on springs 45 are electrically connected to the power supply, a third push rod 48 is fixedly installed on the side of the buffer plate 47 away from the power-on spring 45, and the third push rod 48 extends into the annular placement groove, and a spring is fixedly installed between the buffer plate 47 and the inner wall of the control shell 42.

[0036] When the power-on spring 45 is energized, the power-on spring 45 will contract, and then pull the second insulating plate 43 to move in the direction close to the annular lifting plate 8. The movement of the second insulating plate 43 can connect the circuits of the two third power boards 46 using the third conductive plate 44, and then the motor 6 can work. Because the buffer plate 47 and the inner wall of the control housing 42 are fixedly installed with a spring, the third push rod 48 will also move downward when the annular lifting plate 8 descends. At this time, the spring is in a stretched state. When the spring loses its pressure, it will contract and push the third push rod 48 to move. The downward movement of the third push rod 48 can drive When the buffer plate 47 and the third conductive plate 44 move, the connection between the two third power connection plates 46 will not be disconnected. When the power-on spring 45 is de-energized and the annular lifting plate 8 moves to the top of the annular placement groove, the third push rod 48 will be pushed to move away from the annular lifting plate 8, and then the buffer plate 47 and the second insulating plate 43 will be pushed to move upward. Because the power-on spring 45 is de-energized at this time, the third conductive plate 44 will disconnect the connection between the two third power connection plates 46, so that the motor 6 stops working. In this way, when the cleaning is completed, the cleaning device 49 can be stopped in the annular placement groove more accurately, so that the next cleaning can be better carried out.

[0037] As an embodiment of the present invention, refer to Figure 7 The hybrid body 1 is provided with a power connection slot 35, a first electromagnet 40 is fixedly installed inside the power connection slot 35, and the first electromagnet 40 is electrically connected to the first power connection plate 29, a first insulating plate 37 is slidably installed on the side of the power connection slot 35 away from the first electromagnet 40, a spring is fixedly installed between the side of the first insulating plate 37 away from the first electromagnet 40 and the inner wall of the power connection slot 35, an iron sheet 38 is fixedly installed on one end of the first insulating plate 37 close to the first electromagnet 40, a second conductive plate 39 is fixedly installed inside the first insulating plate 37, two second power connection plates 41 that cooperate with the second conductive plate 39 are fixedly installed on the inner wall of the power connection slot 35, and the two second power connection plates 41 are electrically connected to the power supply and the power-on spring 45 respectively, and a blocking mechanism that prevents the two second power connection plates 41 from being connected is fixedly installed inside the hybrid body 1.

[0038] When the first electromagnet 40 is energized, the iron sheet 38 is attracted to move toward the first electromagnet 40, and then the circuits of the two second power connection plates 41 are connected by the second conductive plate 39, so that the power-on spring 45 is connected to the circuit. When the first electromagnet 40 is disconnected from the circuit, because a spring is fixedly installed between the first insulating plate 37 and the inner wall of the power connection slot 35, the first insulating plate 37 will move away from the first electromagnet 40, and then the connection between the two second power connection plates 41 is disconnected, so that the power-on spring 45 stops working, so that the power-on spring 45 can be connected to the circuit in time, so that the opening and closing of the motor 6 can be better controlled, and the cleaning can be better performed.

[0039] As an embodiment of the present invention, refer to Figure 7 The blocking mechanism includes a blocking groove opened on the upper wall of the power connection groove, a blocking block 36 is slidably installed inside the blocking groove 35, a second push rod 34 is fixedly installed on the upper end of the blocking block 36, and the second push rod 34 extends to the bottom wall of the mixing body 1, a support plate 33 is fixedly installed on the upper end of the second push rod 34, and a spring is fixedly installed between the blocking block 36 and the inner wall of the blocking groove.

[0040] When there is more asphalt in the mixing body 1, the support plate 33 will be pressed to move toward the direction close to the second push rod 34. The movement of the second push rod 34 can make the blocking block 36 move between the first electromagnet 40 and the first insulating plate 37, so as to prevent the two second power connection plates 41 from being connected. When there is less asphalt in the mixing body 1, because a spring is fixedly installed between the blocking block 36 and the inner wall of the power connection groove 35, the blocking block 36 will move upward, and then push the second push rod 34 and the support plate 33 to move upward. At this time, the blocking will be released, so that the first insulating plate 37 can move toward the direction close to the first electromagnet 40. In this way, when there is more asphalt inside the mixing body 1, cleaning will not be performed, and when there is less asphalt inside, cleaning will be performed. In this way, whether cleaning is performed can be controlled by the amount of asphalt inside the mixing body 1.

When the lifting plate 15 moves to the bottom of the connection groove, the push plate 28 will move away from the high-power power board 13, and then the first power board 29 is disconnected from the high-power power board 13, so that the first power board 29 can be powered on in time, and the cleaning device 49 can clean the inner wall of the mixing body 1 in time.

[0044] When the lifting plate 15 moves to the top of the connecting groove, it will push the first lifting column 26 to move away from the lifting plate 15. The movement of the first lifting column 26 can push the third piston 25 to move away from the first lifting column 26, and then the gas in the third chamber 24 enters the moving groove 27 through the pipeline, pushing the push plate 28 to move toward the lifting plate 15. At the same time, the movement of the push plate 28 can push the gas on the side of the push plate 28 close to the lifting plate 15 into the fourth chamber 30 through the pipeline, and then the fourth piston 31 and the second lifting column 32 move toward the lifting plate 15. When the lifting plate 15 moves to the top of the connecting groove, the third piston 25 can be pushed away from the first lifting column 26. Then, the gas in the third chamber 24 enters the moving groove 27 through the pipeline, pushing the push plate 28 to move toward the lifting plate 15. At the same time, the movement of the push plate 28 can push the gas on the side of the push plate 28 close to the lifting plate 15 into the fourth chamber 30 through the pipeline, and then the fourth piston 31 and the second lifting column 32 move toward the lifting plate 15. When the push plate 28 moves to the bottom of the connecting groove, the second lifting column 32 will be pushed to move away from the lifting plate 15. The movement of the second lifting column 32 can push the gas inside the fourth cavity 30 into the moving groove 27 through the pipeline, and then the push plate 28 moves away from the lifting plate 15. The movement of the push plate 28 can push the gas on the side of the push plate 28 away from the lifting plate 15 into the third cavity 24 through the pipeline, and then the first lifting column 26 returns to the top wall of the connecting groove. In this way, when the heating tube 3 ends its work, the first power board 29 can be connected to the circuit in time, and the inner wall of the mixing body 1 can be cleaned in time.

[0045] As an embodiment of the present invention, refer to Figure 2 , Figure 3 and Figure 4A sealing groove is provided inside the mixing body 1 , a sealing plate 51 is slidably installed inside the sealing groove, and an electric push rod 50 is fixedly installed on one side of the top of the sealing plate 51 close to the reciprocating screw rod 7 .

[0046] When the two second power connection plates 41 are connected, the electric push rod 50 will work and then push the sealing plate 51 to move away from the electric push rod 50. The movement of the sealing plate 51 will loosen the seal of the reciprocating screw rod 7, allowing the annular lifting plate 8 to be lifted and lowered. When the two second power connection plates 41 disconnect the circuit, the electric push rod 50 will disconnect the circuit, then shrink the electric push rod 50, and then pull the sealing plate 51 to move towards the electric push rod 50. The movement of the sealing plate 51 can seal the reciprocating screw rod 7 to prevent asphalt from sticking to the reciprocating screw rod 7. In this way, when it is not cleaned, the reciprocating screw rod 7 can be sealed to prevent the reciprocating screw rod 7 from being stained with asphalt, thereby increasing the service life of the reciprocating screw rod 7.

[0047] Working principle: When the device is started, the temperature of the asphalt inside the mixing body 1 is low. When the temperature of the asphalt inside the mixing body 1 is low, the first conductive plate 16 will connect the circuits of the two high-power power boards 13, and then the heating tube 3 will quickly heat the asphalt inside the mixing body 1. The rise in the temperature of the asphalt inside the mixing body 1 can expand the temperature-sensitive medium 10, and then push the sliding plug 11 to move away from the temperature-sensitive medium 10. The movement of the temperature-sensitive medium 10 can push the first push rod 12 to move, and then push the lifting plate 15 to move away from the first push rod 12. When the temperature of the asphalt reaches the set range, the circuits of the two high-power power boards 13 will be disconnected, and the circuits of the two low-power power boards 14 will be connected. The circuit is connected, and then the temperature of the asphalt inside the mixing body 1 is slowly increased. When the temperature of the asphalt inside the mixing body 1 is about to exceed the set range value, the connection between the two low-power power boards 14 will be disconnected, so that the heating pipe 3 stops working, and then the temperature of the asphalt is reduced. When the temperature of the asphalt is about to be lower than the set range value, the low-power power board 14 will be connected, and then the temperature of the asphalt will continue to increase, so that the asphalt changes within the set range value all the time, so that one of the temperatures of the asphalt can be within the set range value. When the lifting plate 15 moves to the top of the connecting groove, it will push the first trapezoidal column 20 to move away from the lifting plate 15. The movement of the first trapezoidal column 20 can push the first piston 19 to move, and then the first piston 19 moves the first cavity 1 8 is pushed into the contraction groove 17, and then the gas inside the contraction groove 17 will push the contraction plate 52 to move away from the lifting plate 15. The movement of the contraction plate 52 can drive the low-power power board 14 to move, and at the same time, it will push the gas on the side of the contraction plate 52 away from the low-power power board 14 to move into the second cavity 21, and then push the second piston 22 to move in the direction close to the lifting plate 15. The movement of the first piston 19 can make the second trapezoidal column 23 extend. When the lifting plate 15 moves to the position of the second trapezoidal column 23, it will push the second trapezoidal column 23 to move away from the lifting plate 15, and then push the gas in the second cavity 21 to move into the contraction groove 17. The gas in the contraction groove 17 will push The shrink plate 52 and the low-power power board 14 move toward the direction close to the lifting plate 15, and then the circuits of the two low-power power boards 14 are connected by the first conductive plate 16. When the shrink plate 52 moves toward the direction close to the lifting plate 15, the gas on the side of the shrink plate 52 close to the lifting plate 15 can be pushed into the first cavity 18, and then the gas in the first cavity 18 will push the first piston 19 and the first trapezoidal column 20 to move toward the direction close to the lifting plate 15, and then the first trapezoidal column 20 is extended. In this way, when the temperature of the asphalt inside the mixing body 1 is about to be lower than the set range, the heating pipe 3 can heat the asphalt in time, and when the temperature inside the mixing body 1 is about to be higher than the set range, the heating pipe 3 can stop heating in time.To prevent the asphalt temperature from being too high and accelerate the aging speed of the asphalt, when the lifting plate 15 moves to the top of the connecting groove, it will push the first lifting column 26 to move away from the lifting plate 15. The movement of the first lifting column 26 can push the third piston 25 to move away from the first lifting column 26, and then the gas in the third cavity 24 enters the moving groove 27 through the pipeline, pushing the push plate 28 to move in the direction close to the lifting plate 15, and then the first power connection plate 29 is connected to the high-power power connection plate 13. At the same time, the movement of the push plate 28 can push the gas on the side of the push plate 28 close to the lifting plate 15 into the fourth cavity 30 through the pipeline, and then the fourth piston 31 and the second lifting column 32 move in the direction close to the lifting plate 15. When the two first power boards 29 are connected, the first electromagnet 40 will work. When the first electromagnet 40 is energized, the iron sheet 38 can be attracted to move toward the first electromagnet 40, and then the circuits of the two second power boards 41 are connected by the second conductive plate 39, so that the power spring 45 is connected to the circuit. When there is more asphalt in the mixing body 1, the support plate 33 will be pressed to move toward the second push rod 34. The blocking block 36 can be moved between the first electromagnet 40 and the first insulating plate 37 through the movement of the second push rod 34, so that the connection between the two second power boards 41 can be prevented. When there is less asphalt in the mixing body 1, the blocking block 36 and the inner wall of the power connection slot are fixedly installed with a spring. The spring, so the blocking block 36 will move upward, and then push the second push rod 34 and the support plate 33 to move upward, then the blocking will be released, so that the first insulating plate 37 can move in the direction close to the first electromagnet 40, so that when there is more asphalt inside the mixing body 1, it will not be cleaned, and when there is less asphalt inside, it will be cleaned. When the two second power-on plates 41 are connected, the circuit of the power-on spring 45 will be connected. When the power-on spring 45 is energized, the power-on spring 45 will shrink, and then pull the second insulating plate 43 to move in the direction close to the annular lifting plate 8. Through the movement of the second insulating plate 43, the circuit of the two third power-on plates 46 can be connected by the third conductive plate 44, and then the motor 6 can work. Because a spring is fixedly installed between the buffer plate 47 and the inner wall of the control housing 42, the third push rod 48 will also move downward when the annular lifting plate 8 descends. The downward movement of the third push rod 48 can drive the buffer plate 47 and the third conductive plate 44 to move. At this time, the connection between the two third power connection plates 46 will not be disconnected. At the same time, when the two second power connection plates 41 are connected, the electric push rod 50 will work and then push the sealing plate 51 to move away from the electric push rod 50. The movement of the sealing plate 51 will release the seal of the reciprocating screw rod 7, so that the annular lifting plate 8 can be lifted and lowered. When the two second power connection plates 41 disconnect the circuit, the electric push rod 50 will disconnect the circuit and then shrink the electric push rod 50.Then, the sealing plate 51 is pulled to move toward the direction close to the electric push rod 50. The reciprocating screw rod 7 can be sealed by the movement of the sealing plate 51. When the two third power connection plates 46 are connected, the motor 6 will work. When the motor 6 is working, the reciprocating screw rod 7 will be driven to rotate. The rotation of the reciprocating screw rod 7 can make the annular lifting plate 8 rise and fall. The lifting of the annular lifting plate 8 can drive the cleaning device 49 to rise and fall. The inner wall of the mixing body 1 is cleaned by the lifting of the cleaning device 49. When the lifting plate 15 moves to the bottom end of the connecting groove, the second lifting column 32 will be pushed to move away from the lifting plate 15. Then, the gas inside the fourth cavity 30 is pushed into the moving groove 27 through the pipeline. The push plate 28 will move in the direction away from the lifting plate 15. Then, the first power connection plate 29 is disconnected from the high-power power connection plate 13. The movement of the push plate 28 can push The gas on the push plate 28 away from the lifting plate 15 side is pushed into the third cavity 24 through the pipeline, and then the first lifting column 26 returns to the top wall of the connecting groove. When the first power board 29 is disconnected, the first electromagnet 40 will stop working. Because the first insulating plate 37 and the inner wall of the power connection groove 35 are fixedly installed with a spring, the first insulating plate 37 will move away from the first electromagnet 40, and then disconnect the two second power boards 41, so that the power spring 45 stops working. When the power spring 45 is de-energized and the annular lifting plate 8 moves to the top of the annular placement groove, it will push the third push rod 48 to move away from the annular lifting plate 8, and then push the buffer plate 47 and the second insulating plate 43 to move upward. Because the power spring 45 is de-energized at this time, the third conductive plate 44 will disconnect the two third power boards 46, so that the motor 6 stops working.
