Description

Technical Field

[0001] The invention relates to the technical field of degassing machines, in particular to a vacuum degassing machine with sealing self-inspection. Background Art

[0002] In many industrial production and scientific research fields, such as electronic packaging, chemical material preparation, coating production, etc., removing bubbles from liquids is a critical and challenging task.

[0003] Traditional vacuum degassing machines often use a fixed degassing procedure. For high-viscosity liquids, the resistance to the movement of bubbles in them is relatively large. It is difficult to quickly separate the bubbles from the liquid by relying solely on conventional vacuum treatment. In a vacuum environment, although bubbles have a natural tendency to rise, for some bubbles that aggregate into larger clumps, their movement speed is slow, affecting the overall degassing efficiency. Most existing vacuum degassing machines lack effective means to promote the separation and movement of these bubbles.

[0004] At the same time, attention should also be paid to the sealing problem of existing vacuum degassing machines. If the sealing is poor, outside air will continue to penetrate into the equipment, resulting in the inability to maintain a stable vacuum degree. This will not only seriously affect the degassing effect, but also increase the load on the vacuum pump and reduce its service life.

[0005] Therefore, the sealing and degassing efficiency of the vacuum degassing machine are the key issues that need to be solved and optimized. Summary of the invention

[0006] The purpose of the present invention is to provide a vacuum degassing machine with sealing self-checking function to solve the problems in the prior art.

[0007] To achieve the above object, the present invention provides the following technical solutions: The vacuum degassing machine with self-test of sealing performance comprises a chassis, a centrifugal unit, a degassing unit and a detection unit. The chassis is placed on a horizontal basis. A transparent observation window is provided on the upper surface of the chassis shell. A control panel is provided on the chassis shell. The centrifugal unit is fixedly installed inside the chassis. The degassing unit is fixedly installed inside the centrifugal unit. The degassing unit is used for quickly removing bubbles inside the object to be processed. The detection unit is used for detecting the vacuum degree inside the chassis. The detection unit is fixedly installed inside the chassis.

[0008] The chassis is used to install and fix the centrifugal unit, the debubbling unit and the detection unit. The centrifugal unit is used to rotate the object to be processed, the debubbling unit is used to quickly remove bubbles from the object to be processed, and the detection unit is used to detect the vacuum seal inside the chassis. When the object to be processed is placed in the chassis, the detection unit is started to vacuum the inside of the chassis, and the object to be processed is rotated by the centrifugal unit, thereby starting the debubbling unit to quickly remove the bubbles in the object to be processed, thereby improving the debubbling efficiency of the vacuum debubbling machine. The vacuum degree inside the chassis is detected by the detection unit, and the pressure is maintained in the event of leakage to avoid affecting the debubbling effect.

[0009] Furthermore, the centrifugal unit includes a driving motor, a containing cylinder, a turntable, a straight rod, a connecting sleeve and a mixing drum. The fixed end of the driving motor is fixedly installed on the inner surface of one end of the chassis close to the horizontal foundation. The output end of the driving motor passes through the containing cylinder and is fixedly connected to the turntable. The containing cylinder is fixedly installed in the middle of the output end of the driving motor. A groove is provided at the end of the turntable away from the horizontal foundation. The straight rod is fixedly installed on the inner wall of the groove of the turntable. One end of the connecting sleeve is fixedly connected to the mixing drum, and the other end is rotatably installed on the straight rod. The mixing drum is fixedly connected to the degassing unit.

[0010] After the liquid to be treated is placed in the mixing drum, the staff rotates the connecting sleeve on the straight rod to adjust the mixing drum to 45 degrees with the horizontal axis, and then controls the drive motor to start and drive the turntable to rotate in a clockwise direction, thereby driving the mixing drum to rotate under the transmission action of the connecting sleeve. Under the action of centrifugal force, the liquid to be treated flows counterclockwise in the mixing drum, breaking the stable state of the liquid to be treated, thereby performing degassing treatment.

[0011] Furthermore, the degassing unit includes a forward and reverse motor, an installation box, a driving gear, a driven gear, a rotating column, a swing arm, a conductive plate, a compression spring, a fixed plate, a magnet, a magnetic ring, a stirring plate, a torsion spring, a memory spring hose, a counterweight, a coil, an electric telescopic rod 1, a buffer spring, a bubble breaking plate, a pull rope, a connecting pipe and an electric telescopic rod 2. The fixed end of the forward and reverse motor is fixedly installed on the outer surface of the connecting pipe, the output end of the forward and reverse motor is connected to the fixed end of the electric telescopic rod 1, and a magnet is fixedly installed on the end of the output end of the electric telescopic rod 1. The electric telescopic rod 1 is installed inside the connecting pipe, one end of the connecting pipe is fixedly connected to the fixed end of the forward and reverse motor, and the other end of the connecting pipe is fixedly connected to the inner surface of the stirring drum. The installation box is fixedly installed on the output end of the forward and reverse motor, the driving gear is fixedly installed on the outer surface of the fixed end of the electric telescopic rod 1, the driving gear is meshed with the driven gear, one end of the rotating column is fixedly connected to the driven gear, and the other end is rotatably connected to the fixed plate. The swing arm is fixedly installed on the rotating column The outer surface of the moving column, the swing arm is electrically connected to the external controller, the conductive plate is electrically connected to the memory spring hose, the conductive plate is slidably mounted in the arc groove provided on the fixed plate, the compression spring is mounted in the arc groove of the fixed plate, the fixed plate is fixedly mounted on the inner surface of one end of the mounting box close to the horizontal foundation, the magnetic ring is slidably mounted on the outer surface of the connecting pipe, the magnetic ring is connected to the stirring plate through a torsion spring, the magnetic ring is electrically connected to the second electric telescopic rod, one end of the memory spring hose is fixedly mounted on the inner surface of one end of the stirring plate close to the connecting pipe, and the other end is fixedly connected to the counterweight block, a memory spring is arranged inside the memory spring hose, the coil is evenly wound on the outer surface of the connecting pipe, the second fixed ends of the electric telescopic rod are obliquely fixedly mounted on the outer surface of the connecting pipe, the second telescopic ends of the electric telescopic rod are fixedly connected to the bubble breaking plate, both ends of the buffer spring are fixedly connected to the bubble breaking plate, one end of the pull rope passes through the mounting box and is fixedly connected to the rotating column, and the other end is fixedly connected to the end of the stirring plate, and the magnetism of the magnet is opposite to that of the magnetic ring.

[0012] The controller controls the start of the forward and reverse motors to drive the driving gear to rotate counterclockwise at a certain speed, thereby driving the driven gear to rotate one circle. In this process, on the one hand, the forward and reverse motors drive the electric telescopic rod to rotate, and the controller controls the forward and reverse motors to rotate clockwise while controlling the electric telescopic rod to contract, thereby driving the magnet to move upward. Under the action of magnetic force, the magnetic ring is driven to slide upward along the connecting pipe synchronously. The magnetic ring drives the stirring plate to rotate synchronously upward counterclockwise while the effective number of turns of the coil gradually decreases and the current increases. At this time, the current in the coil is transmitted to the electric telescopic rod 2 through the magnetic ring, thereby extending the electric telescopic rod 2, stretching the buffer spring while pushing the bubble breaking plate toward the inner wall of the stirring drum, and dispersing the bubbles that rise to the surface of the liquid in the horizontal direction to prevent the bubbles from agglomerating and entering again. In the liquid, it affects the degassing effect and squeezes the bubbles overflowing on the surface of the liquid, thereby improving the efficiency of the bubble removal of the device. On the other hand, when the driven gear rotates, the pull rope is reeled in under the action of the rotating column, thereby pulling the compression torsion spring of the stirring plate to fold upward. At the same time, the rotating column drives the pendulum rod to contact the conductive plate during rotation. At this time, the current transmitted to the pendulum rod by the controller is transmitted to the memory spring hose through the conductive plate. The memory spring receives the current and contracts, thereby pulling the counterweight block to move toward the connecting pipe. At this time, the rotating upward folded stirring plate evenly stirs the treated liquid and is consistent with the rotation direction of the treated liquid, so that a spiral upward flow path is formed in the rotating liquid, thereby quickly bringing the bubbles in the liquid to the liquid surface, and cooperating with the bubble breaking plate to quickly remove the bubbles, thereby improving the degassing efficiency of the device.

[0013] When the controller controls the forward and reverse motor to rotate slowly clockwise and controls the electric telescopic rod to extend at the same time, the magnet drives the magnetic ring to move downward and drives the stirring plate to rotate slowly downward. At this time, the clockwise rotation of the forward and reverse motor drives the rotating column to rotate in the opposite direction under the transmission action of the driving gear and the driven gear, so that the pull rope is untangled and the compression spring is reset during the reverse rotation of the swing rod. The swing rod continues to rotate and no longer contacts the conductive plate, so that the memory spring hose stops receiving current, thereby extending and pushing the counterweight to reset, and cooperating with the restoring force of the torsion spring itself to restore the stirring plate to a horizontal state, scraping off the bubbles attached to the inner wall of the mixing drum while reducing the viscosity of the liquid and increasing the overflow speed of the bubbles in the liquid. When the magnetic ring moves downward, the effective number of turns of the coil increases, the resistance increases, and the current decreases. At this time, the electric telescopic rod 2 drives the bubble breaking plates to approach each other under the action of the restoring force of the buffer spring itself, and scrapes the bubbles overflowing from the inclined liquid surface again, thereby jointly improving the bubble removal efficiency.

[0014] Furthermore, the detection unit includes an air pump, a sealing plate, a slide, a guide column and a displacement sensor. The air pump is fixedly mounted on the outer surface of the chassis, the sealing plate is provided with an exhaust port, the sealing plate is fixedly mounted on the outer surface of one end of the chassis away from the horizontal base, the displacement sensor is fixedly mounted inside the sealing plate, the slide is slidably mounted on the guide column, and the displacement sensors are fixedly connected at both ends of the guide column.

[0015] After the air inside the chassis is pumped out by the air pump, the chassis reaches the preset pressure value and a vacuum state is formed inside. If a poor seal occurs during the degassing process, the pressure gradually increases as the external gas enters the chassis from the sealing plate, pushing the slide to move on the guide column. At this time, the displacement sensor detects that the position of the slide has changed, thereby feeding back an electrical signal to the controller. The controller controls the air pump to start, continuously extracting gas from the chassis, and maintaining the pressure inside the chassis, thereby avoiding the influence of poor sealing on the degassing effect.

[0016] Furthermore, the gear ratio between the driving gear and the driven gear is 1:5.

[0017] In order to facilitate the slow winding of the pull rope on the rotating column, it is avoided that the winding speed is too fast, which causes the folding angle of the stirring plate to exceed the bearing capacity of the torsion spring, thereby causing the torsion spring to deform and be unable to recover, thereby affecting the degassing effect.

[0018] Furthermore, one end of the coil close to the installation box is a current input end.

[0019] In order to reduce the effective number of turns of the coil and increase the current when the magnetic ring moves upward, the second electric telescopic rod drives the bubble breaking plate to extend to both sides, and the bubbles rising to the surface of the liquid are dispersed in the horizontal direction to prevent the bubble clusters from re-merging and entering the liquid again, affecting the degassing effect.

[0020] Furthermore, there are two bubble breaking plates, and the two bubble breaking plates have the same inclination angle as the mixing drum.

[0021] In order to keep the bubble breaking plate level with the inclined liquid surface in the mixing drum, it is easier to squeeze and break the bubble clusters overflowing on the liquid surface, thereby improving the degassing efficiency.

[0022] Furthermore, the counterclockwise rotation speed of the forward and reverse motor is greater than the clockwise rotation speed.

[0023] In order to make the forward and reverse motor rotate counterclockwise, the stirring plate is synchronously rotated counterclockwise under the transmission action of the electric telescopic rod and the magnet, keeping the same direction as the liquid rotation, thereby increasing the liquid rotation speed and increasing the shear force inside the liquid, which helps to tear larger bubbles into smaller bubbles. A faster rotation speed will enhance the convection of the liquid and make the liquid mixed more fully in the axial direction. When the forward and reverse motor rotates clockwise to drive the stirring plate to rotate slowly, the impact on the counterclockwise rotation of the liquid is reduced.

[0024] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention drives the stirring plate to rotate counterclockwise upward synchronously through the magnetic ring in the degassing unit, while the effective number of turns of the coil gradually decreases, the current increases, and the current is transmitted to the electric telescopic rod 2 through the magnetic ring, pushing the bubble breaking plate to move toward the inner wall of the stirring drum, and dispersing the bubbles rising to the surface of the liquid in the horizontal direction to prevent the bubbles from agglomerating and entering the liquid again to affect the degassing effect. At the same time, the bubbles overflowing on the surface of the liquid are squeezed and broken, thereby improving the bubble removal efficiency of the device.

[0025] 2. The present invention reels the pull rope by rotating the rotating column, thereby pulling the compression torsion spring of the stirring plate to fold upward. At the same time, the rotating column drives the rocker arm to contact the conductive plate during rotation. At this time, the current transmitted to the rocker arm by the controller is transmitted to the memory spring hose through the conductive plate. The memory spring receives the current and contracts, thereby pulling the counterweight block to move toward the connecting pipe. At this time, the rotating upward-folded stirring plate evenly stirs the treated liquid and rotates in the same direction as the treated liquid, forming a spiral upward flow path in the rotating liquid, thereby quickly bringing the bubbles in the liquid to the surface, and cooperating with the bubble breaking plate to quickly remove the bubbles, thereby improving the degassing efficiency of the device.

[0026] 3. The present invention unwinds the pull rope by rotating the column in the opposite direction, and the compression spring resets during the reverse rotation of the swing arm. The swing arm continues to rotate and no longer contacts the conductive plate, so that the memory spring hose stops receiving current, thereby extending and pushing the counterweight block to reset. The torsion spring's own restoring force restores the stirring plate to a horizontal state, and the bubbles attached to the inner wall of the stirring drum are scraped off while reducing the viscosity of the liquid, thereby increasing the overflow speed of the bubbles in the liquid. When the magnetic ring moves downward, the effective number of turns of the coil increases, the resistance becomes larger, and the current becomes smaller. Under the action of the buffer spring's own restoring force, the bubble breaking plates are driven closer to each other, and the bubbles overflowing from the inclined liquid surface are scraped off, thereby jointly improving the bubble removal efficiency.

[0027] 4. The present invention detects the change in the position of the sliding piece through a displacement sensor, thereby feeding back an electrical signal to the controller. The controller controls the air pump to start, continuously extracts gas from the inside of the chassis, and maintains the pressure inside the chassis, thereby avoiding the influence of poor sealing on the degassing effect.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example: Figure 1-Figure 14 As shown, the present invention provides a technical solution: like Figure 1 , 2 As shown, a vacuum degassing machine with sealing self-inspection includes a chassis 1, a centrifugal unit 2, a degassing unit 3 and a detection unit 4. The chassis 1 is placed on a horizontal basis, a transparent observation window is provided on the upper surface of the chassis 1 shell, a control panel is provided on the chassis 1 shell, the centrifugal unit 2 is fixedly installed inside the chassis 1, the degassing unit 3 is fixedly installed inside the centrifugal unit 2, the degassing unit 3 is used for quickly removing bubbles inside the object to be processed, the detection unit 4 is used for detecting the vacuum degree inside the chassis 1, and the detection unit 4 is fixedly installed inside the chassis 1.

[0032] The chassis 1 is used for installing and fixing the centrifugal unit 2, the debubbling unit 3 and the detection unit 4. The centrifugal unit 2 is used for rotating the object to be processed, the debubbling unit 3 is used for quickly removing bubbles from the object to be processed, and the detection unit 4 is used for vacuum sealing detection inside the chassis 1. When the object to be processed is placed in the chassis 1, the detection unit 4 is started to evacuate the inside of the chassis 1, and the object to be processed is rotated by the centrifugal unit 2, so as to start the debubbling unit 3 to quickly remove bubbles in the object to be processed, thereby improving the debubbling efficiency of the vacuum debubbling machine. The vacuum degree inside the chassis 1 is detected by the detection unit 4, and the pressure is maintained in the event of leakage to avoid affecting the debubbling effect.

[0033] like Figure 3 , 4 As shown in Figures 5 and 6, the centrifugal unit 2 includes a driving motor 21, a containing cylinder 22, a turntable 23, a straight rod 24, a connecting sleeve 25 and a mixing drum 26. The fixed end of the driving motor 21 is fixedly mounted on the inner surface of the chassis 1 close to the horizontal foundation. The output end of the driving motor 21 passes through the containing cylinder 22 and is fixedly connected to the turntable 23. The containing cylinder 22 is fixedly mounted in the middle of the output end of the driving motor 21. A groove is provided at the end of the turntable 23 away from the horizontal foundation. The straight rod 24 is fixedly mounted on the inner wall of the groove of the turntable 23. One end of the connecting sleeve 25 is fixedly connected to the mixing drum 26, and the other end is rotatably mounted on the straight rod 24. The mixing drum 26 is fixedly connected to the degassing unit 3.

[0034] After the liquid to be treated is placed in the mixing drum 26, the staff rotates the connecting sleeve 25 on the straight rod 24 to adjust the mixing drum 26 to 45 degrees with the horizontal axis, and then controls the drive motor 21 to start the turntable 23 to rotate in a clockwise direction, thereby driving the mixing drum 26 to rotate under the transmission action of the connecting sleeve 25. Under the action of centrifugal force, the liquid to be treated flows counterclockwise in the mixing drum 26, breaking the stable state of the liquid to be treated, thereby performing degassing treatment.

[0035] like Figure 6 , 7, 8, 9, 10, 11, 12, and 13, the degassing unit 3 includes a forward and reverse motor 31, a mounting box 32, a driving gear 33, a driven gear 34, a rotating column 35, a swing rod 36, a conductive plate 37, a compression spring 38, a fixed plate 39, a magnet 310, a magnetic ring 311, a stirring plate 312, a torsion spring 313, a memory spring hose 314, a counterweight 315, a coil 316, an electric telescopic rod 1 317, a buffer spring 318, a bubble breaking plate 319, a pull rope 320, a connecting pipe 321, and an electric telescopic rod 2 322. The fixed end of the forward and reverse motor 31 is fixedly mounted on the outer surface of the connecting pipe 321. The output end of the rotating motor 31 is connected to the fixed end of the electric telescopic rod 317, and a magnet 310 is fixedly installed at the end of the output end of the electric telescopic rod 317. The electric telescopic rod 317 is installed inside the connecting pipe 321, and one end of the connecting pipe 321 is fixedly connected to the fixed end of the forward and reverse motor 31, and the other end of the connecting pipe 321 is fixedly connected to the inner surface of the mixing drum 26. The mounting box 32 is fixedly installed at the output end of the forward and reverse motor 31, and the driving gear 33 is fixedly installed on the outer surface of the fixed end of the electric telescopic rod 317. The driving gear 33 is meshed with the driven gear 34. One end of the rotating column 35 is fixedly connected to the driven gear 34, and the other end is fixed to the fixed The plate 39 is rotatably connected, the swing rod 36 is fixedly mounted on the outer surface of the rotating column 35, the swing rod 36 is electrically connected to the external controller, the conductive plate 37 is electrically connected to the memory spring hose 314, the conductive plate 37 is slidably mounted in the arc groove opened in the fixed plate 39, the compression spring 38 is mounted in the arc groove of the fixed plate 39, the fixed plate 39 is fixedly mounted on the inner surface of one end of the installation box 32 close to the horizontal foundation, the magnetic ring 311 is slidably mounted on the outer surface of the connecting pipe 321, the magnetic ring 311 is connected to the stirring plate 312 through the torsion spring 313, the magnetic ring 311 is electrically connected to the electric telescopic rod 2 322, and one end of the memory spring hose 314 is fixedly mounted on The stirring plate 312 is close to the inner surface of one end of the connecting tube 321, and the other end is fixedly connected to the counterweight block 315. A memory spring is arranged inside the memory spring hose 314, and the coil 316 is evenly wound around the outer surface of the connecting tube 321. The fixed end of the electric telescopic rod 322 is obliquely fixedly installed on the outer surface of the connecting tube 321, and the telescopic end of the electric telescopic rod 322 is fixedly connected to the bubble breaking plate 319. Both ends of the buffer spring 318 are fixedly connected to the bubble breaking plate 319. One end of the pull rope 320 passes through the installation box 32 and is fixedly connected to the rotating column 35, and the other end is fixedly connected to the end of the stirring plate 312. The magnetism of the magnet 310 is opposite to that of the magnetic ring 311.

[0036] The controller controls the start of the forward and reverse motor 31 to drive the driving gear 33 to rotate counterclockwise at a certain speed, thereby driving the driven gear 34 to rotate one circle. In this process, on the one hand, the forward and reverse motor 31 drives the electric telescopic rod 1 317 to rotate, and the controller controls the forward and reverse motor 31 to rotate clockwise while controlling the electric telescopic rod 1 317 to contract, thereby driving the magnet 310 to move upward, and under the action of the magnetic force, the magnetic ring 311 is driven to slide upward along the connecting pipe 321 synchronously, and the magnetic ring 311 drives the stirring plate 312 to rotate synchronously upward counterclockwise while the effective number of turns of the coil 316 gradually decreases, and the current becomes larger. At this time, the current in the coil 316 is transmitted to the electric telescopic rod 2 322 through the magnetic ring 311, thereby extending the electric telescopic rod 2 322, stretching the buffer spring 318, and pushing the bubble breaking plate 319 to move toward the inner wall of the stirring drum 26, so that the bubbles rising to the surface of the liquid are dispersed in the horizontal direction to avoid air bubbles. The bubbles gather and enter the liquid again, affecting the degassing effect. At the same time, the bubbles overflowing on the surface of the liquid are squeezed and broken, thereby improving the efficiency of the bubble removal of the device. On the other hand, when the driven gear 34 rotates, the pull rope 320 is reeled in under the action of the rotating column 35, thereby pulling the stirring plate 312 to compress the torsion spring 313 and fold it upward. At the same time, the rotating column 35 drives the swing rod 36 to contact the conductive plate 37 during rotation. At this time, the current transmitted to the swing rod 36 by the controller is transmitted to the memory spring hose 314 through the conductive plate 37. The memory spring receives the current and contracts at this time, thereby pulling the counterweight block 315 to move toward the connecting pipe 321. At this time, the rotating upward folded stirring plate 312 evenly stirs the treated liquid while being consistent with the rotation direction of the treated liquid, so that a spiral upward flow path is formed in the rotating liquid, thereby quickly bringing the bubbles in the liquid to the liquid surface, and cooperating with the bubble breaking plate 319 to quickly remove the bubbles, thereby improving the degassing efficiency of the device.

[0037] When the controller controls the forward and reverse motor 31 to rotate slowly clockwise and controls the electric telescopic rod 317 to extend, the magnet 310 drives the magnetic ring 311 to move downward and drives the stirring plate 312 to rotate slowly downward. At this time, the clockwise rotation of the forward and reverse motor 31 drives the rotating column 35 to rotate in the opposite direction under the transmission action of the driving gear 33 and the driven gear 34, so that the pull rope 320 is unwound and the compression spring 38 is reset during the reverse rotation of the swing rod 36. The swing rod 36 continues to rotate and no longer contacts the conductive plate 37, so that the memory spring hose 314 stops receiving current, thereby extending the telescopic rod 317. The long push counterweight block 315 is reset, and the restoring force of the torsion spring 313 itself is used to restore the stirring plate 312 to a horizontal state, so as to scrape off the bubbles attached to the inner wall of the stirring drum 26 and reduce the viscosity of the liquid, thereby increasing the overflow speed of the bubbles in the liquid. When the magnetic ring 311 moves downward, the effective number of turns of the coil 316 increases, the resistance becomes larger, and the current becomes smaller. At this time, the electric telescopic rod 322 drives the bubble breaking plate 319 to move closer to each other under the action of the restoring force of the buffer spring 318 itself, and the bubbles overflowing from the inclined liquid surface are scraped again, thereby jointly improving the bubble removal efficiency.

[0038] like Figure 3 , 14 As shown, the detection unit 4 includes an air pump 41, a sealing plate 42, a slide 43, a guide column 44 and a displacement sensor 45. The air pump 41 is fixedly mounted on the outer surface of the chassis 1, the sealing plate 42 is provided with an exhaust port, the sealing plate 42 is fixedly mounted on the outer surface of the chassis 1 away from the horizontal base, the displacement sensor 45 is fixedly mounted inside the sealing plate 42, the slide 43 is slidably mounted on the guide column 44, and the displacement sensors 45 are fixedly connected at both ends of the guide column 44.

[0039] After the air inside the chassis 1 is pumped out by the air pump 41, the chassis 1 reaches a preset pressure value and a vacuum state is formed inside. If a poor seal occurs during the degassing process, the pressure gradually increases as the external gas enters the chassis 1 from the sealing plate 42, pushing the slide 43 to move on the guide column 44. At this time, the displacement sensor 45 detects that the position of the slide 43 has changed, thereby feeding back an electrical signal to the controller. The controller controls the air pump 41 to start, continuously extract gas from the chassis 1, and maintain the pressure inside the chassis 1, thereby avoiding the influence of poor sealing on the degassing effect.

[0040] like Fig.11 As shown, the gear ratio between the driving gear 33 and the driven gear 34 is 1:5.

[0041] In order to facilitate the slow winding of the pull rope 320 on the rotating column 35, it is avoided that the winding speed is too fast, which causes the folding angle of the stirring plate 312 to exceed the bearing capacity of the torsion spring 313, thereby causing the torsion spring 313 to deform and be unable to recover, thereby affecting the degassing effect.

[0042] like Figure 7 , 8 As shown, one end of the coil 316 close to the mounting box 32 is a current input end.

[0043] In order to reduce the effective number of turns of the coil 316 and increase the current when the magnetic ring 311 moves upward, the electric telescopic rod 322 drives the bubble breaking plate 319 to extend to both sides, so as to disperse the bubbles rising to the surface of the liquid in the horizontal direction, so as to prevent the bubble clusters from re-merging and entering the liquid again, thereby affecting the degassing effect.

[0044] like Figure 7 , 8 As shown, there are two bubble breaking plates 319 , and the two bubble breaking plates 319 are inclined at the same angle as the mixing drum 26 .

[0045] In order to make the bubble breaking plate 319 and the inclined liquid surface in the mixing drum 26 remain level, it is more convenient to squeeze and break the bubble clusters overflowing on the liquid surface, thereby improving the degassing efficiency.

[0046] like Figure 7 , 8 As shown, the counterclockwise rotation speed of the forward and reverse motor 31 is greater than the clockwise rotation speed.

[0047] In order to make the forward and reverse motor 31 rotate counterclockwise, the stirring plate 312 is synchronously rotated counterclockwise under the transmission action of the electric telescopic rod 317 and the magnet 310, maintaining the same direction as the rotation of the liquid, thereby increasing the rotation speed of the liquid and increasing the shear force inside the liquid, which helps to tear larger bubbles into smaller bubbles. A faster rotation speed will enhance the convection of the liquid and make the liquid mixed more fully in the axial direction. When the forward and reverse motor 31 rotates clockwise to drive the stirring plate 312 to rotate slowly, the impact on the counterclockwise rotation of the liquid is reduced.

[0048] Working principle of the present invention: After the liquid to be treated is placed in the mixing drum 26, the staff rotates the connecting sleeve 25 on the straight rod 24 to adjust the mixing drum 26 to 45 degrees with the horizontal axis, and then controls the drive motor 21 to start the turntable 23 to rotate in a clockwise direction, thereby driving the mixing drum 26 to rotate under the transmission action of the connecting sleeve 25. Under the action of centrifugal force, the liquid to be treated flows counterclockwise in the mixing drum 26, breaking the stable state of the liquid to be treated, thereby performing degassing treatment.

[0049] The controller controls the start of the forward and reverse motor 31 to drive the driving gear 33 to rotate counterclockwise at a certain speed, thereby driving the driven gear 34 to rotate one circle. In this process, on the one hand, the forward and reverse motor 31 drives the electric telescopic rod 1 317 to rotate, and the controller controls the forward and reverse motor 31 to rotate clockwise while controlling the electric telescopic rod 1 317 to contract, thereby driving the magnet 310 to move upward, and under the action of the magnetic force, the magnetic ring 311 is driven to slide upward along the connecting pipe 321 synchronously, and the magnetic ring 311 drives the stirring plate 312 to rotate synchronously upward counterclockwise while the effective number of turns of the coil 316 gradually decreases, and the current becomes larger. At this time, the current in the coil 316 is transmitted to the electric telescopic rod 2 322 through the magnetic ring 311, thereby extending the electric telescopic rod 2 322, stretching the buffer spring 318, and pushing the bubble breaking plate 319 to move toward the inner wall of the stirring drum 26, so that the bubbles rising to the surface of the liquid are dispersed in the horizontal direction to avoid air bubbles. The bubbles gather and enter the liquid again, affecting the degassing effect. At the same time, the bubbles overflowing on the surface of the liquid are squeezed and broken, thereby improving the efficiency of the bubble removal of the device. On the other hand, when the driven gear 34 rotates, the pull rope 320 is reeled in under the action of the rotating column 35, thereby pulling the stirring plate 312 to compress the torsion spring 313 and fold it upward. At the same time, the rotating column 35 drives the swing rod 36 to contact the conductive plate 37 during rotation. At this time, the current transmitted to the swing rod 36 by the controller is transmitted to the memory spring hose 314 through the conductive plate 37. The memory spring receives the current and contracts at this time, thereby pulling the counterweight block 315 to move toward the connecting pipe 321. At this time, the rotating upward folded stirring plate 312 evenly stirs the treated liquid while being consistent with the rotation direction of the treated liquid, so that a spiral upward flow path is formed in the rotating liquid, thereby quickly bringing the bubbles in the liquid to the liquid surface, and cooperating with the bubble breaking plate 319 to quickly remove the bubbles, thereby improving the degassing efficiency of the device.

[0050] When the controller controls the forward and reverse motor 31 to rotate slowly clockwise and controls the electric telescopic rod 317 to extend, the magnet 310 drives the magnetic ring 311 to move downward and drives the stirring plate 312 to rotate slowly downward. At this time, the clockwise rotation of the forward and reverse motor 31 drives the rotating column 35 to rotate in the opposite direction under the transmission action of the driving gear 33 and the driven gear 34, so that the pull rope 320 is unwound and the compression spring 38 is reset during the reverse rotation of the swing rod 36. The swing rod 36 continues to rotate and no longer contacts the conductive plate 37, so that the memory spring hose 314 stops receiving current, thereby extending the telescopic rod 317. The long push counterweight block 315 is reset, and the restoring force of the torsion spring 313 itself is used to restore the stirring plate 312 to a horizontal state, so as to scrape off the bubbles attached to the inner wall of the stirring drum 26 and reduce the viscosity of the liquid, thereby increasing the overflow speed of the bubbles in the liquid. When the magnetic ring 311 moves downward, the effective number of turns of the coil 316 increases, the resistance becomes larger, and the current becomes smaller. At this time, the electric telescopic rod 322 drives the bubble breaking plate 319 to move closer to each other under the action of the restoring force of the buffer spring 318 itself, and the bubbles overflowing from the inclined liquid surface are scraped again, thereby jointly improving the bubble removal efficiency.

[0051] After the air inside the chassis 1 is pumped out by the air pump 41, the chassis 1 reaches a preset pressure value and a vacuum state is formed inside. If a poor seal occurs during the degassing process, the pressure gradually increases as the external gas enters the chassis 1 from the sealing plate 42, pushing the slide 43 to move on the guide column 44. At this time, the displacement sensor 45 detects that the position of the slide 43 has changed, thereby feeding back an electrical signal to the controller. The controller controls the air pump 41 to start, continuously extract gas from the chassis 1, and maintain the pressure inside the chassis 1, thereby avoiding the influence of poor sealing on the degassing effect.
