Description

Technical Field

[0001] The invention relates to the technical field of heat treatment, in particular to an ultra-large trolley-type gas heat treatment furnace. Background Art

[0002] Heat treatment furnace is a general term for industrial furnaces that perform various metal heat treatments on metal workpieces. The temperature is generally lower than that of a heating furnace. Heat treatment furnaces can adopt various types of heating furnaces, but require strict control of the furnace temperature and furnace atmosphere.

[0003] Most heat treatment furnaces are heated by gas fuel. In order to accurately control the furnace temperature, some heat treatment furnaces are heated by electricity. Modern heat treatment (especially chemical heat treatment) processes are becoming more and more complex, and there are many forms of heat treatment furnaces. For continuous heat treatment processes, suitable continuous heat treatment furnaces must be equipped. For cyclic heat treatment processes, forced circulation of controlled atmosphere and mechanization and automation of furnace operation are required.

[0004] If the original heat treatment furnace cannot be cleaned inside in time, the effect of the next heat treatment furnace will be reduced. If it is not cleaned for a long time, a lot of high-temperature chemicals may accumulate, increasing the probability of failure of the heat treatment furnace.

[0005] To this end, an ultra-large trolley-type gas heat treatment furnace is proposed. Summary of the invention

[0006] The object of the present invention is to provide an ultra-large trolley-type gas heat treatment furnace, which solves the problems raised in the above-mentioned background technology by cleaning the high-temperature chemicals generated inside the gas heat treatment furnace after use.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A super-large trolley-type gas heat treatment furnace comprises a heat treatment body, support frames are symmetrically fixedly installed on both sides of the heat treatment body, an annular cleaning plate is movably installed on the top wall of the support frame, two second moving blocks are fixedly installed on both sides of the annular cleaning plate, a lifting mechanism for controlling the lifting of the annular cleaning plate is fixedly installed inside the heat treatment body, a first moving block is movably installed inside the annular cleaning plate, a horizontal cleaning plate for cleaning the bottom wall of the heat treatment body is fixedly installed at the lower end of the first moving block, a control mechanism for controlling the horizontal movement of the first moving block is fixedly installed inside the annular cleaning plate, and when the horizontal cleaning plate moves to the bottom of the heat treatment body, the control mechanism controls the first moving block to move horizontally.

[0009] When cleaning is required, the lifting mechanism is first used to control the annular cleaning plate to clean the inner wall of the heat treatment body. Then, when the annular cleaning plate descends to the bottom wall of the heat treatment body, the control mechanism will control the first moving block and the horizontal cleaning plate inside the annular cleaning plate to move horizontally. The bottom wall of the heat treatment body is cleaned at one end of the bottom wall of the heat treatment body by the first moving block and the horizontal cleaning plate. In this way, the interior of the heat treatment body can be cleaned in time, and the deposition of high-temperature chemicals inside the heat treatment body can be effectively prevented, the failure rate of the high-temperature treatment furnace can be reduced, and the service life of the high-temperature treatment furnace can be increased. The manufacturing materials of the cleaning device are all high-temperature resistant materials.

[0010] Preferably, a power supply is fixedly installed inside the heat treatment body, the lifting mechanism includes a mounting groove fixedly opened inside the heat treatment body, a first motor is fixedly installed inside the mounting groove, and the first motor is electrically connected to the power supply, a first reciprocating screw is rotatably installed on the output end of the first motor, and the second moving block is threadedly connected to the first reciprocating screw, an opening and closing mechanism for controlling the opening and closing of the first motor is fixedly installed inside the heat treatment body, a positioning mechanism is fixedly installed inside the heat treatment body, and a sealing collection mechanism is fixedly opened on the rear end bottom wall of the heat treatment body.

[0011] First, when cleaning is needed, the opening and closing mechanism is used to make the first motor work. The work of the first motor can drive the first reciprocating screw to rotate. Because the rotation of the first reciprocating screw can make the second moving block rise and fall, the lifting of the second moving block can drive the annular cleaning plate to rise and fall, and then the inner wall of the heat treatment body is cleaned by the descent of the annular cleaning plate. Then, when the annular cleaning plate descends to the bottom wall of the heat treatment body, the positioning mechanism can temporarily stop the work of the first motor. After a pause, the first motor continues to work, and then moves the annular cleaning plate upward until the second moving block rises to the top wall. The first motor stops working, so that the high-temperature chemicals on the inner wall of the heat treatment body can be cleaned, and the cleaning can be carried out in time, which can reduce the failure rate of the high-temperature treatment furnace and increase the service life of the high-temperature treatment furnace.

[0012] Preferably, the control mechanism includes a second motor fixedly mounted inside the annular cleaning plate, and the second motor is electrically connected to a power supply, a second reciprocating screw is rotatably mounted on the output end of the second motor, and the first movable block is threadedly connected to the second reciprocating screw, and a delay mechanism for extending the working time of the second motor is fixedly mounted inside the annular cleaning plate.

[0013] When the annular cleaning plate moves to the bottom wall of the heat treatment body, the delay mechanism controls the second motor to work, and the second motor can rotate the second reciprocating screw, and the rotation of the second reciprocating screw can make the first moving block move horizontally, and the horizontal movement of the first moving block drives the horizontal cleaning plate to move, and then the horizontal cleaning plate is used to clean the bottom wall of the heat treatment body. When the horizontal cleaning plate is cleaned, the first moving block on the horizontal cleaning plate can be returned to the leftmost position of the second reciprocating screw, and then the second motor stops working, so that the bottom wall of the heat treatment body can be cleaned in time, the deposition of dust and high-temperature chemicals can be prevented, and the high-temperature treatment furnace can maintain a good high-temperature treatment effect every time.

[0014] Preferably, the opening and closing mechanism includes an opening and closing shell fixedly installed inside the heat treatment body, a first electromagnet is fixedly installed inside the opening and closing shell, a first lifting plate is movably installed at the lower end of the first electromagnet, a permanent magnet that cooperates with the first electromagnet is fixedly installed inside the first lifting plate, a second power connection block is fixedly installed on one side of the first lifting plate, and the second power connection block is electrically connected to the power supply, a second conductive block that cooperates with the second power connection block is fixedly installed inside the opening and closing shell, and the second conductive block is electrically connected to the first motor, a second lifting plate is movably installed on the side of the opening and closing shell away from the first electromagnet, and two first springs are symmetrically installed between the second lifting plate and the first lifting plate, a second pressing column is fixedly installed on the side of the second lifting plate away from the first electromagnet, and the second pressing column extends to the mounting groove close to the second moving block, a second spring is fixedly installed between the second lifting plate and the bottom wall of the opening and closing shell, and a switch mechanism for controlling the opening and closing of the first electromagnet is fixedly installed inside the heat treatment body.

[0015] When cleaning is required, the power supply of the first electromagnet is connected by using the switch mechanism. Because a first spring is installed between the first lifting plate and the second lifting plate, the operation of the first electromagnet can push the permanent magnet and the first lifting plate to move downward, and then connect the second power connection block to the second conductive block. The connection between the second power connection block and the second conductive block can enable the first motor to work, and then the second moving block is lowered. When the second moving block is lowered, the second pressing column will extend into the installation groove due to the second spring, and when the second moving block moves to the set position, it will push the switch mechanism to disconnect the circuit of the first electromagnet. , and because of the second spring, the second pressing column can extend all the way outside, so that when the first electromagnet stops working, the second power connection block continues to be connected to the second conductive block. When the second moving block moves up to the top wall of the heat treatment body, it will push the second pressing column to move upward. The movement of the second pressing column can push the first lifting plate to move upward, and then disconnect the second power connection block from the second conductive block to stop the first motor. In this way, when the second moving block moves to the top of the belt, the power supply of the first motor can be disconnected in time, so that the next cleaning of the inner wall of the heat treatment body can maintain a good cleaning effect.

[0016] Preferably, the switch mechanism includes a switch slot fixedly opened inside the heat treatment body, a first power connection block is movably installed inside the switch slot, and the first power connection block is electrically connected to the power supply, a first pressing column is fixedly installed on one side of the first power connection block, and the first pressing column extends to the outside of the heat treatment body, a trapezoidal block is fixedly installed on the other side of the first power connection block, and the trapezoidal block can extend into the installation slot, a first conductive block is fixedly installed on one side of the switch slot close to the inner wall of the heat treatment body, and the first conductive block is electrically connected to the first electromagnet.

[0017] After using the high-temperature treatment furnace, press the first pressing column, and the first power connection block is moved in the direction close to the installation groove by pressing the first pressing column, and then the first power connection block and the first conductive block are contacted with each other, and the circuit of the first electromagnet can be connected through the contact between the first power connection block and the first conductive block, so that the first electromagnet works, and the trapezoidal block can be moved in the direction close to the installation groove while the first power connection block moves in the direction close to the installation groove, and then the trapezoidal block is extended into the installation groove, and when the second moving block moves downward and touches the trapezoidal block, it will move the trapezoidal block in the direction away from the installation groove, and then push the first power connection block to move, disconnect the first power connection block from the first conductive block, and disconnect the first power connection block from the first conductive block, so that the first electromagnet can stop working, so that when cleaning is needed, the inner wall of the heat treatment body can be cleaned in time, the deposition of internal waste can be prevented, and the service life of the high-temperature treatment furnace can be extended.

[0018] Preferably, the positioning mechanism includes a positioning groove fixedly opened inside the heat treatment body, a third power connection block is movably installed inside the positioning groove, and the third power connection block is electrically connected to the first motor, a third pressing column is fixedly installed on the upper end of the third power connection block, and the third pressing column extends into the installation groove, a third spring is fixedly installed on the third pressing column and the top wall of the positioning groove, two third conductive blocks are symmetrically installed on both sides of the third power connection block, and the third conductive block is electrically connected to the power supply, racks are fixedly installed on the upper ends of the two third conductive blocks, two reduction gears are fixedly installed in the positioning groove, and the racks are gear-meshed with the reduction gears, and a fourth spring is fixedly installed on the lower end of the third conductive block and the bottom wall of the positioning groove.

[0019] When the second moving block moves to the bottom wall of the heat treatment body, the second moving block will press the third pressing column to move downward, and then the third pressing column will push the third power connection block to move downward, and then the third power connection block will disconnect from the third conductive block. At the same time, because the fourth spring is installed at the lower end of the third conductive block, when the third power connection block descends, the fourth spring will pull the third conductive block to move downward, but because the rack and the reduction gear inside the positioning groove are installed at the upper end of the third conductive block, the descending speed of the third conductive block will be reduced, and then the time for the third conductive block to be disconnected from the third power connection block will be extended. When the second moving block moves upward, the third spring will pull the third power connection block to move upward, and then drive the third conductive block to move upward, so that the position of the annular cleaning plate can be accurately positioned to the bottom wall of the heat treatment body, so that the horizontal cleaning plate can effectively clean the bottom wall of the heat treatment body.

[0020] Preferably, the delay mechanism includes a delay shell fixedly installed inside the annular cleaning plate, a second electromagnet is fixedly installed inside the delay shell, and the second electromagnet is electrically connected to the second conductive block, an insulating plate is movably installed on the side of the delay shell away from the second electromagnet, an iron sheet that cooperates with the second electromagnet is fixedly installed on the end of the insulating plate close to the second electromagnet, a fourth power transmission block is fixedly installed on one side of the insulating plate, and the fourth power transmission block is electrically connected to the power supply, a fourth conductive block that cooperates with the fourth power transmission block is fixedly installed inside the delay shell, and the fourth conductive block is electrically connected to the second motor, and a pulling plate mechanism is fixedly installed inside the annular cleaning plate so that the fourth power transmission block and the fourth conductive block will not be connected when the insulating plate rises.

[0021] First, when power is turned on, the third power connection block and the third conductive block are connected together. The connection between the third power connection block and the third conductive block enables the second electromagnet to work. The work of the second electromagnet can attract the iron sheet to move upward. The upward movement of the iron sheet can drive the insulating plate and the fourth power transmission block to move upward. At the same time, when the iron sheet moves upward, the fourth conductive block can be pulled to the left by using the pulling plate mechanism, so that the fourth power transmission block will not be connected to the fourth conductive block when the insulating plate and the iron sheet rise. When the insulating plate and the iron sheet move to the uppermost end, the gas inside the pulling plate mechanism will return to the uppermost end through the conduit. To the delay shell, and then make the fourth conductive block return to the place where it can contact with the fourth power transmission block. When the third power connection block is disconnected from the third conductive block, the circuit of the second electromagnet will be disconnected, and then the insulating plate and the iron sheet will slowly drop, and then the fourth power transmission block will be connected to the fourth conductive block. The second motor is operated through the connection between the fourth power transmission block and the fourth conductive block, so that the connection time of the fourth power transmission block and the fourth conductive block can be extended, and the extended time can make the horizontal cleaning plate return to the place where it was just started to clean after cleaning, so that the bottom wall of the heat treatment body can be better cleaned.

[0022] Preferably, the pulling plate mechanism includes a cylinder body fixedly installed inside the annular cleaning plate, and a guide tube is fixedly installed between the cylinder body and the delay shell, a piston is movably installed inside the cylinder body, and the side of the piston away from the fourth conductive block is elastically connected to the inner wall of the cylinder body, a pull rod is fixedly installed between the piston and the fourth conductive block, and the end of the piston away from the fourth conductive block is elastically connected to the inner wall of the cylinder body.

[0023] When the insulating plate and iron sheet inside the delay shell move upward, they can push the gas inside the delay shell into the cylinder through the conduit, and then the gas will push the piston to the left. The left movement of the piston can drive the pull rod to move, and then the pull rod drives the fourth conductive block to the left. When the insulating plate and the iron sheet move to the uppermost end, because of the elastic connection between the piston and the inner wall of the cylinder, the piston will be pulled to the right, and then the gas in the cylinder will be pushed back into the delay shell through the conduit, and then the fourth conductive block will be pushed to a position where it can contact the fourth power transmission block. This can prevent the fourth power transmission block from connecting with the fourth conductive block when the insulating plate moves up, and enable the horizontal cleaning plate to better clean the bottom wall of the heat treatment body.

[0024] Preferably, the sealed collection mechanism includes a feed opening fixedly opened on the bottom wall of the rear end of the heat treatment body, a sealing plate for sealing is installed at the bottom end of the feed opening, an energized spring for opening the feed opening is fixedly installed on one side of the sealing plate, and the energized spring is electrically connected to the second conductive block, a collection box is fixedly installed inside the heat treatment body, and the collection box is located at the lower side of the feed opening.

[0025] When the second conductive block is connected to the second power connection block, the energized spring can work at the same time, and then the energized spring pulls the sealing plate to open the discharge port. When the second conductive block is disconnected from the second power connection block, the energized spring pulls the sealing plate to seal the discharge port.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. First, use the annular cleaning plate to clean the inner wall of the heat treatment furnace, and then use the horizontal cleaning plate to clean the bottom wall of the heat treatment furnace. This can clean the high-temperature chemicals inside the heat treatment furnace in time, reduce the failure rate of the high-temperature treatment furnace, and increase the service life of the high-temperature treatment furnace.

[0028] 2. When the annular cleaning plate moves to the bottom wall of the heat treatment furnace, it will push the third pressing column to move downward, and then disconnect the circuit of the first motor to stop the first motor from working. This will enable the annular cleaning plate to stay accurately on the bottom wall, and the horizontal cleaning plate can better clean the bottom wall of the heat treatment furnace.

[0029] 3. When the second electromagnet disconnects the circuit, the fourth power transmission block is connected to the fourth conductive block, and the insulating plate slowly moves downward, thereby extending the time for the fourth power transmission block to be connected to the fourth conductive block. This allows the second motor to start long enough for the first moving block on the horizontal cleaning plate to return to the leftmost position of the second reciprocating screw after the horizontal cleaning plate is cleaned.

[0030] 4. When cleaning is required, the sealing plate will be opened, and then the cleaned waste will be collected. When the cleaning is completed, the sealing plate will seal the discharge port, which will make it easier to clean and collect the waste and discharge the waste from the heat treatment furnace.

[0044] When cleaning is required, the lifting mechanism is first used to control the annular cleaning plate 3 to clean the inner wall of the heat treatment body 1. Then, when the annular cleaning plate 3 drops to the bottom wall of the heat treatment body 1, the control mechanism will control the first moving block 4 and the horizontal cleaning plate 5 inside the annular cleaning plate 3 to move horizontally. The bottom wall of the heat treatment body 1 is cleaned at one end of the bottom wall of the heat treatment body 1 by the first moving block 4 and the horizontal cleaning plate 5.

The output end of the second motor 32 is rotatably installed with a second reciprocating screw rod 33, and the first moving block 4 is threadedly connected to the second reciprocating screw rod 33. A delay mechanism for extending the working time of the second motor 32 is fixedly installed inside the annular cleaning plate 3.

[0048] When the annular cleaning plate 3 moves to the bottom wall of the heat treatment body 1, the delay mechanism controls the second motor 32 to work, and the second motor 32 can make the second reciprocating screw 33 rotate through the work of the second motor 32, and the rotation of the second reciprocating screw 33 can make the first moving block 4 move horizontally, and the horizontal cleaning plate 5 is driven to move by the horizontal movement of the first moving block 4, and then the bottom wall of the heat treatment body 1 is cleaned by the horizontal cleaning plate 5. After the horizontal cleaning plate 5 is cleaned, the first moving block 4 on the horizontal cleaning plate 5 can be returned to the leftmost position of the second reciprocating screw 33, and then the second motor 32 stops working, so that the bottom wall of the heat treatment body 1 can be cleaned in time, the deposition of dust and high-temperature chemicals can be prevented, and the high-temperature treatment furnace can maintain a good high-temperature treatment effect every time.

A second spring 23 is fixedly installed between the second lifting plate 21 and the bottom wall of the opening and closing shell 14, and a switch mechanism for controlling the opening and closing of the first electromagnet 15 is fixedly installed inside the heat treatment body 1.

[0050] When cleaning is required, the power supply of the first electromagnet 15 is connected by means of the switch mechanism. Since the first spring 20 is installed between the first lifting plate 16 and the second lifting plate 21, the operation of the first electromagnet 15 can push the permanent magnet 17 and the first lifting plate 16 to move downward, and then connect the second power connection block 18 to the second conductive block 19. The connection between the second power connection block 18 and the second conductive block 19 enables the first motor 12 to work, and then the second moving block 6 is lowered. When the second moving block 6 is lowered, the second pressing column 22 will extend toward the inside of the mounting groove 11 due to the second spring 23, and when the second moving block 6 moves to the set position, it will push the switch mechanism to disconnect the first electromagnet. 15, and because of the second spring 23, the second pressing column 22 can extend all the way outside, so that when the first electromagnet 15 stops working, the second power connection block 18 and the second conductive block 19 continue to be connected, and when the second moving block 6 moves up to the top wall of the heat treatment body 1, the second pressing column 22 will be pushed to move upward, and the movement of the second pressing column 22 can push the first lifting plate 16 to move upward, and then disconnect the second power connection block 18 from the second conductive block 19, so that the first motor 12 stops working, so that when the second moving block 6 moves with the top end, the power supply of the first motor 12 can be disconnected in time, so that the cleaning of the inner wall of the heat treatment body 1 next time can maintain a good cleaning effect.

[0051] As an embodiment of the present invention, refer to Figure 4The switch mechanism includes a switch slot fixedly opened inside the heat treatment body 1, a first power connection block 8 is movably installed inside the switch slot, and the first power connection block 8 is electrically connected to the power supply, a first pressing column 7 is fixedly installed on one side of the first power connection block 8, and the first pressing column 7 extends to the outside of the heat treatment body 1, a trapezoidal block 9 is fixedly installed on the other side of the first power connection block 8, and the trapezoidal block 9 can extend into the installation slot 11, a first conductive block 10 is fixedly installed on one side of the switch slot close to the inner wall of the heat treatment body 1, and the first conductive block 10 is electrically connected to the first electromagnet 15.

[0052] After using the high temperature treatment furnace, the first pressing column 7 is pressed, and the first connecting block 8 is moved toward the direction close to the installation groove 11 by pressing the first pressing column 7, and then the first connecting block 8 and the first conductive block 10 are contacted with each other. The circuit of the first electromagnet 15 can be connected through the contact between the first connecting block 8 and the first conductive block 10, so that the first electromagnet 15 works, and the trapezoidal block 9 can be moved toward the direction close to the installation groove 11 while the first connecting block 8 moves toward the direction close to the installation groove 11, and then the trapezoidal block 9 is extended to the installation groove. 11, when the second moving block 6 moves downward and touches the trapezoidal block 9, the trapezoidal block 9 will move away from the mounting groove 11, and then push the first power connection block 8 to move, disconnecting the first power connection block 8 from the first conductive block 10. By disconnecting the first power connection block 8 from the first conductive block 10, the first electromagnet 15 can stop working, so that when cleaning is needed, the inner wall of the heat treatment body 1 can be cleaned in time, the deposition of internal waste can be prevented, and the service life of the high temperature treatment furnace can be extended.

[0053] As an embodiment of the present invention, refer to Figure 7 The positioning mechanism includes a positioning groove 25 fixedly opened inside the heat treatment body 1, a third power connection block 27 is movably installed inside the positioning groove 25, and the third power connection block 27 is electrically connected to the first motor 12, a third pressing column 24 is fixedly installed on the upper end of the third power connection block 27, and the third pressing column 24 extends into the mounting groove 11, and a third spring 26 is fixedly installed between the third pressing column 24 and the top wall of the positioning groove 25, two third conductive blocks 28 are symmetrically installed on both sides of the third power connection block 27, and the third conductive blocks 28 are electrically connected to the power supply, and racks 30 are fixedly installed on the upper ends of the two third conductive blocks 28, two reduction gears 31 are fixedly installed in the positioning groove 25, and the racks 30 are gear-meshed with the reduction gears 31, and a fourth spring 29 is fixedly installed between the lower end of the third conductive block 28 and the bottom wall of the positioning groove 25.

[0054] When the second moving block 6 moves to the bottom wall of the heat treatment body 1, the second moving block 6 will press the third pressing column 24 to move downward, and then the third pressing column 24 will push the third power connection block 27 to move downward, and then the third power connection block 27 will disconnect from the third conductive block 28. At the same time, because the fourth spring 29 is installed at the lower end of the third conductive block 28, when the third power connection block 27 descends, the fourth spring 29 will pull the third conductive block 28 to move downward, but because the rack 30 and the reduction gear 31 inside the positioning groove 25 are installed at the upper end of the third conductive block 28, the descending speed of the third conductive block 28 will be reduced, and then the time for the third conductive block 28 to disconnect from the third power connection block 27 will be extended. When the second moving block 6 moves upward, the third spring 26 will pull the third power connection block 27 to move upward, and then drive the third conductive block 28 to move upward, so that the position of the annular cleaning plate 3 can be accurately positioned to the bottom wall of the heat treatment body 1, so that the horizontal cleaning plate 5 can effectively clean the bottom wall of the heat treatment body 1.

[0055] As an embodiment of the present invention, refer to Figure 8 The delay mechanism includes a delay housing 34 fixedly mounted inside the annular cleaning plate 3, a second electromagnet 35 fixedly mounted inside the delay housing 34, and the second electromagnet 35 is electrically connected to the second conductive block 19, an insulating plate 36 is movably mounted on a side of the delay housing 34 away from the second electromagnet 35, an iron sheet 37 that cooperates with the second electromagnet 35 is fixedly mounted on one end of the insulating plate 36 close to the second electromagnet 35, a fourth power transmission block 38 is fixedly mounted on one side of the insulating plate 36, and the fourth power transmission block 38 is electrically connected to the power supply, a fourth conductive block 39 that cooperates with the fourth power transmission block 38 is fixedly mounted inside the delay housing 34, and the fourth conductive block 39 is electrically connected to the second motor 32, and a pulling plate mechanism is fixedly mounted inside the annular cleaning plate 3 so that the fourth power transmission block 38 and the fourth conductive block 39 will not be connected when the insulating plate 36 rises.

[0056] First, when the power is turned on, the third power connection block 27 and the third conductive block 28 are connected together. The connection between the third power connection block 27 and the third conductive block 28 can make the second electromagnet 35 work. The operation of the second electromagnet 35 can attract the iron sheet 37 to move upward. The upward movement of the iron sheet 37 can drive the insulating plate 36 and the fourth power transmission block 38 to move upward. At the same time, when the iron sheet 37 moves upward, the fourth conductive block 39 can be pulled to the left by using the pull plate mechanism, so that when the insulating plate 36 and the iron sheet 37 rise, the fourth power transmission block 38 and the fourth conductive block 39 will not be connected. When the insulating plate 36 and the iron sheet 37 move to the uppermost end, the insulating plate 36 will release the seal and pressure on the conduit 40, and then the pull plate mechanism The gas inside the structure will return to the delay housing 34 through the conduit 40, and then the fourth conductive block 39 will return to the place where it can contact the fourth power transmission block 38. When the third power connection block 27 is disconnected from the third conductive block 28, the circuit of the second electromagnet 35 will be disconnected, and then the insulating plate 36 and the iron sheet 37 will slowly descend, and then the fourth power transmission block 38 will be connected to the fourth conductive block 39. The second motor 32 is operated through the connection between the fourth power transmission block 38 and the fourth conductive block 39, so that the connection time of the fourth power transmission block 38 and the fourth conductive block 39 can be extended, and the extended time can make the horizontal cleaning plate 5 return to the place where it was just cleaned after cleaning, so that the bottom wall of the heat treatment body 1 can be better cleaned.

[0057] As an embodiment of the present invention, refer to Fig. 9 The pulling plate mechanism includes a cylinder body 41 fixedly installed inside the annular cleaning plate 3, and a guide tube 40 is fixedly installed between the cylinder body 41 and the delay shell 34, a piston 42 is movably installed inside the cylinder body 41, and the side of the piston 42 away from the fourth conductive block 39 is elastically connected to the inner wall of the cylinder body 41, a pull rod 43 is fixedly installed between the piston 42 and the fourth conductive block 39, and the end of the piston 42 away from the fourth conductive block 39 is elastically connected to the inner wall of the cylinder body 41.

[0058] When the insulating plate 36 and the iron sheet 37 inside the delay housing 34 move upward, they can push the gas inside the delay housing 34 into the cylinder 41 through the conduit 40, and then the gas will push the piston 42 to move leftward. The leftward movement of the piston 42 can drive the pull rod 43 to move, and then the pull rod 43 drives the fourth conductive block 39 to move leftward. When the insulating plate 36 and the iron sheet 37 move to the uppermost end, because the piston 42 is elastically connected to the inner wall of the cylinder 41, the piston 42 will be pulled to move to the right, and then the gas in the cylinder 41 will be pushed back into the delay housing 34 through the conduit 40, and then the fourth conductive block 39 will be pushed to a position where it can contact the fourth power transmission block 38. This can prevent the fourth power transmission block 38 from connecting with the fourth conductive block 39 when the insulating plate 36 moves upward, so that the horizontal cleaning plate 5 can better clean the bottom wall of the heat treatment body 1.

[0059] As an embodiment of the present invention, refer to Figure 2 The sealing and collecting mechanism includes a feed opening 47 fixedly opened on the bottom wall of the rear end of the heat treatment body 1, a sealing plate 45 for sealing is installed at the bottom end of the feed opening 47, an energizing spring 44 for opening the feed opening 47 is fixedly installed on one side of the sealing plate 45, and the energizing spring 44 is electrically connected to the second conductive block 19, and a collecting box 46 is fixedly installed inside the heat treatment body 1, and the collecting box 46 is located at the lower side of the feed opening 47.

[0060] When the second conductive block 19 is connected to the second power connection block 18 , the power spring 44 can work at the same time, and then the power spring 44 pulls the sealing plate 45 to open the discharge port 47 . When the second conductive block 19 is disconnected from the second power connection block 18 , the power spring 44 pulls the sealing plate 45 to seal the discharge port 47 .

[0061] Working principle: when cleaning is needed, the first pressing column 7 is pressed, and the first power connection block 8 is moved toward the direction close to the installation groove 11 by pressing the first pressing column 7, and then the first power connection block 8 and the first conductive block 10 are contacted with each other, and the circuit of the first electromagnet 15 can be connected through the contact between the first power connection block 8 and the first conductive block 10, so that the first electromagnet 15 can work, and when the first power connection block 8 moves toward the direction close to the installation groove 11, the trapezoidal block 9 can be moved toward the direction close to the installation groove 11, and then the trapezoidal block 9 is extended into the installation groove 11, and the power supply of the first electromagnet 15 can be connected through the connection between the first power connection block 8 and the first conductive block 10, because the first lifting plate 16 and the second lifting plate 21 are installed with a first Spring 20, so when the first electromagnet 15 works, it can push the permanent magnet 17 and the first lifting plate 16 to move downward, and then connect the second power block 18 with the second conductive block 19. When the second conductive block 19 is connected to the second power block 18, the power-on spring 44 can work at the same time, and then the power-on spring 44 pulls the sealing plate 45 to open the discharge port 47, and the first motor 12 can work through the connection between the second power block 18 and the second conductive block 19, and then the second moving block 6 is lowered. When the second moving block 6 is lowered, the second pressing column 22 will extend toward the inside of the mounting groove 11 due to the second spring 23, and when the second moving block 6 moves downward, it touches The trapezoidal block 9 moves away from the mounting groove 11, and then pushes the first power connection block 8 to move, disconnecting the first power connection block 8 from the first conductive block 10. By disconnecting the first power connection block 8 from the first conductive block 10, the first electromagnet 15 can stop working, and when the second moving block 6 moves to the set position, it pushes the switch mechanism to disconnect the circuit of the first electromagnet 15. Because of the second spring 23, the second pressing column 22 can extend outside all the time, so that when the first electromagnet 15 stops working, the second power connection block 18 and the second conductive block 19 continue to be connected. When the second moving block 6 moves to the bottom wall of the heat treatment body 1, the second moving block 6 presses the third pressing column 24 to The third pressing column 24 pushes the third power connection block 27 to move downward, and then the third power connection block 27 is disconnected from the third conductive block 28. At the same time, because the fourth spring 29 is installed at the lower end of the third conductive block 28, when the third power connection block 27 descends, the fourth spring 29 will pull the third conductive block 28 downward. However, because the rack 30 and the reduction gear 31 inside the positioning groove 25 are installed at the upper end of the third conductive block 28, the descending speed of the third conductive block 28 will be reduced, and then the time for the third conductive block 28 to be disconnected from the third power connection block 27 will be extended, so that the annular cleaning plate 3 can stay at the bottom for a period of time. When power is turned on, the third power connection block 27 and the third conductive block 28 are connected together.The connection between the third power connection block 27 and the third conductive block 28 can make the second electromagnet 35 work, and the iron sheet 37 can be attracted to move upward through the work of the second electromagnet 35. The upward movement of the iron sheet 37 can drive the insulating plate 36 and the fourth power transmission block 38 to move upward. At the same time, when the iron sheet 37 moves upward, when the insulating plate 36 and the iron sheet 37 inside the delay housing 34 move upward, the gas in the delay housing 34 can be pushed into the cylinder 41 through the conduit 40, and then the gas will push the piston 42 to move to the left, and the left movement of the piston 42 can drive the pull rod 43 to move, and then the pull rod 43 drives the fourth conductive block 39 to move to the left. When the insulating plate 36 and the iron sheet 37 move to the most When the piston 42 is at the upper end, because the piston 42 is elastically connected to the inner wall of the cylinder 41, the piston 42 will be pulled to the right, and then the gas in the cylinder 41 will be pushed back into the delay housing 34 through the conduit 40, and then the fourth conductive block 39 will be pushed to a position where it can contact the fourth power transmission block 38, so that when the insulating plate 36 and the iron sheet 37 rise, the fourth power transmission block 38 will not be connected to the fourth conductive block 39. When the insulating plate 36 and the iron sheet 37 move to the uppermost end, the gas inside the cylinder 41 will return to the delay housing 34 through the conduit 40, and then the fourth conductive block 39 will return to a position where it can contact the fourth power transmission block 38. When the third power connection block 27 is disconnected from the third conductive block 28, , the circuit of the second electromagnet 35 will be disconnected, and then the insulating plate 36 and the iron sheet 37 will slowly drop, and then the fourth power transmission block 38 will be connected to the fourth conductive block 39, and the second motor 32 will work through the connection between the fourth power transmission block 38 and the fourth conductive block 39, so that the connection time of the fourth power transmission block 38 and the fourth conductive block 39 can be extended, and then the horizontal cleaning plate 5 will clean the bottom of the heat treatment body 1. After the cleaning is completed, the horizontal cleaning plate 5 can return to the place where the cleaning was started, and then the fourth power transmission block 38 is disconnected from the fourth conductive block 39. At this time, the third conductive block 28 and the third power connection block 27 are reconnected, and then the first motor 12 works. When the second moving block 6 moves upward, the third spring 26 will pull the third power connection block 27 to move upward, and then drive the third conductive block 28 to move upward. When the second moving block 6 moves up to the top wall of the heat treatment body 1, it will push the second pressing column 22 to move upward. The movement of the second pressing column 22 can push the first lifting plate 16 to move upward, and then disconnect the second power connection block 18 from the second conductive block 19, so that the first motor 12 stops working. In this way, when the second moving block 6 moves to the top, the power supply of the first motor 12 can be disconnected in time, and when the second conductive block 19 is disconnected from the second power connection block 18, the energized spring 44 pulls the sealing plate 45 to seal the discharge port 47.
