Description

Technical Field

[0001] The present invention relates to the technical field of reactor cleaning, in particular to a self-cleaning enamel reactor and a use method thereof. Background Art

[0002] Enamel reactor is a composite material made of glass containing high silicon dioxide, which is lined on the inner surface of a steel container and firmly adhered to the metal surface through high-temperature sintering. During the use of enameled reactor, a lot of residual unreacted liquid or viscous liquid will adhere to the inner wall of the reactor. If it is not cleaned for a long time, it will cause interaction between different reaction liquids and affect the quality of the reaction liquid. Long-term attachment of residues to the inner wall of the reactor will also cause damage to the inner wall of the reactor, shortening the service life of the reactor.

[0003] In the existing technology, a three-dimensional cleaning nozzle is usually used to flush the inner wall of the reactor. This cleaning method is slow and has low cleaning efficiency. Another method is to clean through a built-in cleaning mechanism. This method also has the following disadvantages: First, some cleaning mechanisms are large in size and will come into contact with the reaction materials when the reactor is working, affecting the chemical reaction of the materials; in addition, some cleaning mechanisms will have cleaning dead corners and will be hindered by the stirring paddle, making it impossible to clean the bottom inner wall of the reactor.

DETAILED DESCRIPTION

[0043] The following is based on Figures 1-17 The present invention provides a self-cleaning enamel reactor and a method for using the same.

[0044] See also Figure 1-Figure 7The embodiment of the present invention provides a technical solution: a self-cleaning enamel reactor, comprising a tank body 1 and a drive shaft 10, which is mounted on the top of the tank body 1 by means of a mechanical seal, and the reduction motor 3 is connected to the drive shaft 10 by a coupling, and can drive the drive shaft 10 to rotate, and the main body of the drive shaft 10 is arranged in the tank body 1, and a stirring paddle 12 is fixedly provided at the bottom end of the drive shaft 10, and the stirring paddle 12 is spaced a certain distance from the inner wall of the bottom end of the tank body 1, and a spiral guide rail 11 is fixedly provided on the upper side of the drive shaft 10, and the spiral guide rail 11 is arranged around the outer circumferential surface of the drive shaft 10, and a guide block 59 is fixedly provided on the lower side of the drive shaft 10, that is, on the side close to the stirring paddle 12, and the spiral guide rail 11 and the guide block 59 are spaced a certain distance along the axial direction of the drive shaft 10.

[0045] And, combined with Figure 6 A slip ring assembly 18 is also provided in the tank body 1. The slip ring assembly 18 includes a stator 181 and a rotor 182. The connection method between the two can be understood by referring to the hydraulic slip ring in the prior art. A spiral groove 63 is provided at the axis of the rotor 182, and the spiral groove 63 fits with the spiral guide rail 11. An arc block 28 is fixed at the lower end of the rotor 182. A vertical groove 281 is provided on the inner side wall of the arc block 28, and the vertical groove 281 fits with the guide block 59. During the axial movement of the slip ring assembly 18 along the drive shaft 10, when the spiral groove 63 contacts the spiral guide rail 11, the drive shaft 10 does not rotate and the rotor 182 rotates. The rotor 182 rotates while generating vertical displacement under the action of the spiral guide rail 11. When the vertical groove 281 contacts the guide block 59, the drive shaft 10 rotates, and the rotor 182 is driven to rotate by the drive shaft 10.

[0046] It should be noted that the reason for setting a certain distance between the spiral guide rail 11 and the guide block 59 is to enable the guide block 59 to be stuck in the vertical groove 281 when the spiral groove 63 is separated from the spiral guide rail 11. If the distance between the two is too large, when the spiral groove 63 is separated from the spiral guide rail 11, the rotor 182 cannot correspond to the vertical groove 281 during the descent process and cannot be stuck. If the distance between the two is too small, the guide block 59 will directly press against the arc block 28, causing the rotor 182 to be unable to fall.

[0047] Optionally, in order to facilitate the guide block 59 to be inserted into the vertical groove 281, a transition bevel groove 282 can be opened on the bottom surface of the arc block 28, and the transition bevel groove 282 is connected to the vertical groove 281. When the spiral groove 63 has not completely separated from the spiral guide rail 11, the guide block 59 contacts the transition bevel groove 282, thereby guiding the guide block 59 into the vertical groove 281 through the transition bevel groove 282.

[0048] In addition, a frame is provided in the tank body 1. The frame is annular and is fixed to the rotor 182. Specifically, the frame consists of an upper fixed plate 15, a lower fixed plate 16 and a cross frame 17. The upper fixed plate 15 and the lower fixed plate 16 are connected by a fixed block 52. One end of the cross frame 17 is fixed to the rotor 182, and the other end is fixed to the lower fixed plate 16. The frame moves synchronously with the rotor 182.

[0049] In addition, a cleaning roller 13 is installed on the peripheral side of the frame. Preferably, the cleaning roller 13 is a brush roller. The material of the cleaning roller 13 needs to be selected according to the properties of the reactants in the reactor to avoid chemical reactions. The rotation axis of the cleaning roller 13 is parallel to the drive shaft 10. The cleaning roller 13 contacts the circumferential inner wall of the tank body 1. When the spiral groove 63 contacts the spiral guide rail 11, the frame rotates to drive the cleaning roller 13 to rotate, thereby cleaning the circumferential inner wall of the tank body 1.

[0050] It should be noted that it is preferred that multiple cleaning rollers 13 are provided, and the multiple cleaning rollers 13 are arranged in a circular array along the frame. The number of cleaning rollers 13, the length of the cleaning rollers 13 and the pitch of the spiral guide rail 11 need to be satisfied. When the frame rotates through a pitch height, it can fully cover the circumferential inner wall within one pitch. For example, when there is only one cleaning roller 13, the length of the cleaning roller 13 is the same as the pitch of the spiral guide rail 11.

[0051] In addition, a cleaning brush 14 is installed on the lower side of the frame. The cleaning brush 14 is arranged along the radial direction of the tank body 1. When the cleaning brush 14 rotates around the axis of the drive shaft 10 for one circle, it can cover the bottom inner wall of the tank body 1. The material of the cleaning brush 14 is the same as that of the cleaning roller 13. When the guide block 59 is fully inserted into the vertical groove 281, the cleaning brush 14 contacts the bottom inner wall of the tank body 1. At this time, the drive shaft 10 is driven to rotate by the reduction motor 3, thereby driving the cleaning brush 14 to rotate at the lower end of the stirring paddle 12 to clean the bottom inner wall of the tank body 1.

[0052] When the reactor is in operation, the frame can be lifted to the top of the tank body 1. Since the reaction materials usually occupy about 50% to 75% of the volume of the reactor when the reactor is in operation, lifting the frame to the top of the reactor can avoid contact with the reaction materials as much as possible, thereby preventing the frame and the cleaning roller 13 from interfering with the reaction process of the materials. When the reactor needs to be cleaned, the frame can be dropped along the axial direction of the tank body 1 to the inner wall of the bottom end, so that the circumferential inner wall and the inner wall of the bottom end can be cleaned respectively by the cleaning roller 13 and the cleaning brush 14.

[0053] In this embodiment, in order to facilitate the axial movement of the frame along the drive shaft 10, a screw lift 4 is also provided on the outside of the tank body 1, which can drive the lifting screw 5 to move in the vertical direction. One end of the lifting screw 5 is fixed on the stator 181, so that when the lifting screw 5 moves in the vertical direction, it drives the frame to move. When the diameter of the stator 181 is small, an extension plate 19 can be fixed on both sides of the stator 181, and the lifting screw 5 is fixed to the extension plate 19, so as to avoid the position of the lifting screw 5 from interfering with the reduction motor 3.

[0054] Optionally, combined Figure 2 and Figure 3 In order to improve the stability of the frame movement, a balance bar 8 can be set on the other side of the tank body 1. The balance bar 8 is arranged parallel to the lifting screw rod 5, and one end of the balance bar 8 is also fixed to the stator 181.

[0055] Optionally, in order to improve the stability of the balance bar 8 and the lifting screw rod 5 during movement, a slot plate 6 is fixed on the mounting frame of the reduction motor 3, and a clamping member 7 is fixed at the top end of the balance bar 8 and the lifting screw rod 5. The clamping member 7 can be inserted into the slot plate 6 and can slide along the vertical direction of the slot plate 6, thereby applying a support to the top end of the balance bar 8 and the lifting screw rod 5.

[0056] It should be noted that the connections between the balance rod 8, the lifting screw rod 5 and the tank body 1 all need to be sealed to ensure the airtightness of the reactor when in use.

[0057] See Figure 4 、 Figure 5 、 Figure 9 and Figure 10 In order to facilitate installation and use, a plurality of fixed frames 62 are fixed on the frame. The plurality of fixed frames 62 are arranged in a circular array on the frame. The number of fixed frames 62 is the same as the cleaning roller 13. A single cleaning roller 13 is installed on a single fixed frame 62 through an elastic support frame 39. The elastic support frame 39 is used to press the cleaning roller 13 toward the circumferential inner wall of the tank body 1 so that the cleaning roller 13 can fully clean the circumferential inner wall of the tank body 1. When a single cleaning roller 13 or the elastic support frame 39 is damaged, the entire fixed frame 62 can be directly removed for replacement or repair without affecting other components.

[0058] Combine Figure 9 and Figure 10The above-mentioned elastic support frame 39 is composed of a parallelogram mechanism and an elastic component, wherein the parallelogram mechanism includes a first side rod 391 and a second side rod 392, one end of the first side rod 391 and the second side rod 392 are rotatably mounted on the fixed frame 62, and the parallelogram mechanism also includes a third side rod 393, the two ends of the third side rod 393 are respectively hinged to the free ends of the first side rod 391 and the second side rod 392 to form a four-bar mechanism, and the cleaning roller 13 is rotatably mounted on the third side rod 393. When the first side rod 391 and the second side rod 392 rotate, the distance between the third side rod 393 and the fixed frame 62 changes, thereby adjusting the distance between the cleaning roller 13 and the inner wall of the tank body 1.

[0059] Optionally, combined Figure 11 In order to clean the cleaning roller 13 in time, a cleaning plate 45 can be fixed on the third side rod 393, and the surface of the cleaning plate 45 has tooth-like protrusions to comb the cleaning roller 13.

[0060] See Figure 9 and Figure 10 The above-mentioned elastic component includes a guide rod 396, which is fixed on the fixed frame 62 and arranged parallel to the third side rod 393. Preferably, the axis of the guide rod 396 passes through the hinge point between the first side rod 391 and the fixed frame 62 and the hinge point between the second side rod 392 and the fixed frame 62. It also includes a support rod 394, one end of the support rod 394 is hinged to the third side rod 393, and the support rod 394 and the first side rod 391 are symmetrically arranged on both sides of the third side rod 393, and the lengths of the first side rod 391, the second side rod 392 and the support rod 394 are all the same.

[0061] In addition, a sliding rod 395 is slidably installed on the guide rod 396, the other end of the support rod 394 is hinged to the sliding rod 395, a tension spring 397 is sleeved on the outer circumference of the guide rod 396, and a stop block 40 is slidably provided on the guide rod 396, one end of the tension spring 397 is fixedly connected to the stop block 40, and the other end of the tension spring 397 is fixedly connected to the sliding rod 395.

[0062] In this embodiment, when the position of the stopper 40 is fixed, the tension spring 397 pulls the sliding rod 395 toward the side close to the first side rod 391 , so that the cleaning roller 13 approaches and contacts the inner wall of the tank body 1 .

[0063] See Figure 4 、 Figure 10 and Figure 12In order to facilitate the adjustment of the elastic force of the elastic support frame 39, a traction rope 51 is fixed on the block 40. The traction rope 51 connects multiple blocks 40 in series, that is, a single traction rope 51 is fixed on each block 40. In order to facilitate the arrangement of the traction rope 51, a hole can be opened on the fixing block 52, and the traction rope 51 is passed through the hole, so that the fixing block 52 is used to guide the traction rope 51.

[0064] In addition, a mounting plate 53 is fixedly provided on the frame, and a first winding assembly 54 and a second winding assembly 55 are respectively installed on both sides of the mounting plate 53. The first winding assembly 54 and the second winding assembly 55 have the same structure.

[0065] One end of the traction rope 51 is fixed to the first winding assembly 54, and the other end is fixed to the second winding assembly 55. By rotating the first winding assembly 54 and the second winding assembly 55, the stopper 40 can be pulled to move by the traction rope 51. Specifically, when the first winding assembly 54 is rotated and the second winding assembly 55 is rotated in the opposite direction, one end of the traction rope 51 is wound, so that the traction rope 51 drives all the stops 40 to move toward the sliding rod 395, thereby moving the cleaning roller 13 toward the side close to the fixed frame 62. When the first winding assembly 54 and the second winding assembly 55 are rotated in the opposite direction, the stopper 40 can be driven to move toward the side of the first side rod 391, thereby moving the cleaning roller 13 toward the inner wall of the tank body 1 without being subjected to external force.

[0066] Combine Figure 13 , a specific structure of the first winding assembly 54 is given below:

[0067] The first winding assembly 54 includes a sleeve shaft 58, a winding shaft 56 and a second spring 57, wherein the sleeve shaft 58 is fixed to the mounting plate 53, the winding shaft 56 passes through the axis of the sleeve shaft 58 and is rotatably connected to the sleeve shaft 58, and the second spring 57 is sleeved on the outer circumference of the winding shaft 56 and is located on one side of the sleeve shaft 58, one end of the second spring 57 is against the mounting plate 53, and the other end is against the retaining ring 562 on the winding shaft 56. A slot 581 is provided on the end surface of the sleeve shaft 58 away from the second spring 57, and a blocking block 561 is fixed on the side of the winding shaft 56 close to the blocking block 581. When the blocking block 561 is embedded in the blocking block 561, the winding shaft 56 cannot rotate. Pulling the winding shaft 56 outward causes the blocking block 561 to disengage from the blocking block 581, and the winding shaft 56 can be rotated. After the external force is removed, the winding shaft 56 is reset under the action of the second spring 57 and is locked again.

[0068] See Figure 4 、 Figure 9 、 Figure 15 and, Figure 16In order to drive the cleaning roller 13 to rotate and improve the cleaning effect, a gear ring 29 is fixed on the outer circumference of the stator 181, and a gear ring 30, a first wheel group 31 and a second wheel group 32 are rotatably installed on the frame, wherein the gear ring 30 can be rotatably installed on the frame through a slewing support, and the first wheel group 31 and the second wheel group 32 are both composed of a transmission gear and a pulley. The transmission gear of the first wheel group 31 is engaged with the gear ring 29, and the transmission gear of the second wheel group 32 is engaged with the internal teeth of the gear ring 30. The pulley of the first wheel group 31 and the pulley of the second wheel group 32 are transmitted through a first transmission belt 35. When the rotor 182 rotates, the stator 181 does not rotate. At this time, the frame rotates with the rotor 182, so that the transmission gear of the first wheel group 31 rotates while rotating with the frame, thereby driving the second wheel group 32 to rotate through the first transmission belt 35, and the second driving gear ring 30 to rotate.

[0069] In addition, a third wheel group 33 is rotatably mounted on the frame. The third wheel group 33 also consists of a transmission gear and a pulley. The transmission gear of the third wheel group 33 is engaged with the outer teeth of the ring gear 30. A fourth wheel group 34 is rotatably provided on the fixed frame 62. The fourth wheel group 34 consists of two pulleys. The pulleys of the third wheel group 33 and the pulleys of the fourth wheel group 34 are transmitted through the second transmission belt 36. The rotation axis of the fourth wheel group 34 coincides with the axis of rotation of the cleaning roller 13 along the parallelogram mechanism.

[0070] In addition, a coaxial wheel 38 is provided on the third side rod 393. The coaxial wheel 38 is coaxial with and coaxially connected to the cleaning roller 13. The coaxial wheel 38 and the pulley of the fourth wheel group 34 are transmitted through the third transmission belt 37, thereby driving the cleaning roller 13 to rotate.

[0071] See Figure 8 、 Figure 9 、 Figure 14 、 Figure 15 and Figure 17 In order to provide cleaning liquid during the cleaning process, the stator 181 has a water inlet end, the rotor 182 has a water outlet end, and an annular tube 41 is installed on the frame. The annular tube 41 can be supported and fixed by the fixing block 52, and the water outlet end is connected to the annular tube 41.

[0072] Specific, combined Figure 17The stator 181 is provided with a first water inlet 20 and a second water inlet 21, which are water inlet ends. The rotor 182 is provided with a first water outlet 26 and a second water outlet 27, which are water outlet ends. A first annular cavity 22 and a second annular cavity 23 are provided at the junction of the stator 181 and the rotor 182. The cleaning liquid entering from the first water inlet 20 first enters the first annular cavity 22 and then passes through the rotor. The first connecting groove 24 on 182 flows to the first water outlet 26, and the cleaning liquid entering from the second water inlet 21 first enters the second annular cavity 23, and then enters the second water outlet 27 through the second connecting groove 25 on the rotor 182. The first water inlet 20 and the second water inlet 21 are in a closed state when the reactor is working. When the reactor needs to be cleaned, open the sealing cover 2 on the tank body 1 and connect the pipeline for conveying the cleaning liquid to the first water inlet 20 and the second water inlet 21 respectively.

[0073] In addition, combined Figure 9 and Figure 10 A nozzle 44 is installed on the first side rod 391, and the water outlet direction of the nozzle 44 is toward the cleaning roller 13 to moisten and rinse the inner wall of the tank body 1, so that the cleaning roller 13 can remove the attachments in the tank body 1. The nozzle 44 is connected to the annular pipe 41. Specifically, a water inlet joint 411 is provided on one side of the annular pipe 41, and a water outlet joint 412 is provided on the other side. There are two water inlet joints 411, which are respectively connected to the first water outlet 26 and the second water outlet 27 through the first connecting pipe 42. There are multiple water outlet joints 412, which correspond to the number of nozzles 44. Each nozzle 44 is connected to the water outlet joint 412 through the second connecting pipe 43, so that the cleaning liquid can enter the nozzle 44 through the annular pipe 41.

[0074] See Figure 5 and Figure 6 In order to facilitate the use of the cleaning brush 14 and improve the cleaning effect of the cleaning brush 14, a rotating shaft 49 is installed on the lower side of the frame, and a telescopic rod 47 is fixed on the rotating shaft 49, and the axis of the telescopic rod 47 is perpendicular to the rotating shaft 49.

[0075] In addition, an arc-shaped plate 46 is fixedly provided at the other end of the telescopic rod 47. The arc-shaped plate 46 is arranged along the radial direction of the tank body 1, and the arc surface of the arc-shaped plate 46 fits with the inner wall of the bottom end of the tank body 1. The cleaning brush 14 is installed on the arc-shaped plate 46. The two can be plugged or snapped together for easy disassembly and assembly, thereby conveniently replacing the cleaning brush 14.

[0076] In addition, a first spring 48 is sleeved on the outer circumference of the telescopic rod 47 , and the first spring 48 can push the cleaning brush 14 toward the bottom inner wall of the tank body 1 , thereby creating a certain friction between the cleaning brush 14 and the bottom inner wall of the tank body 1 .

[0077] See Figure 6-Figure 8 When the frame is at the top end of the tank body 1, in order to reduce the sagging height of the cleaning brush 14 at this time and prevent the cleaning brush 14 from contacting the reaction material, the rotating shaft 49 is rotatably connected to the lower side of the frame, and a damping rotating shaft or torsion spring is provided between the rotating shaft 49 and the frame so that the axis of the telescopic rod 47 is in a horizontal state when the spiral groove 63 contacts the spiral guide rail 11, thereby preventing the cleaning brush 14 from naturally sagging under the action of gravity.

[0078] In addition, a driving gear 50 is fixedly provided at one end of the rotating shaft 49 close to the arc block 28, and an opening for the rotating shaft 49 to pass through is provided on the side of the arc block 28. A rack 60 is provided at the bottom of the driving shaft 10, and the rack 60 is located at the same height as the guide block 59. The driving gear 50 is engaged with the rack 60. When the rotating shaft 49 moves in the vertical direction, the driving gear 50 is forced to rotate, driving the rotating shaft 49 to rotate. Therefore, when the driving gear 50 is not in contact with the rack 60, the telescopic rod 47 is in a horizontal state, and the cleaning brush 14 is folded to the minimum drooping height. When the rotating shaft 49 moves downward to the bottom end, the driving gear 50 rotates 90°, thereby driving the cleaning brush 14 to flip 90° and unfold to the maximum drooping height. In order to facilitate the control of the rotation angle of the driving gear 50, a positioning platform 61 can be fixed on the lower side of the guide block 59. When the rotating shaft 49 moves downward to the bottom end, the bottom end of the arc block 28 contacts the positioning platform 61, thereby limiting the falling height of the rotating shaft 49.

[0079] When the cleaning brush 14 is working, the nozzle 44 continuously sprays cleaning liquid, the cleaning liquid contacts the cleaning brush 14 , and is collected and discharged toward the discharge port 9 at the bottom of the tank body 1 .

[0080] Optionally, two groups of cleaning brushes 14 may be provided, and the two groups of cleaning brushes 14 are symmetrically arranged about the center of the driving shaft 10 . In this case, two groups of driving gears 50 and racks 60 also need to be provided.

[0081] It should be noted that due to the presence of the stirring paddle 12 , in order to avoid interference between the cleaning brush 14 and the stirring paddle 12 during the downward movement, it is necessary to ensure that the position of the cleaning brush 14 corresponds to the gap between the blades of the stirring paddle 12 when the guide block 59 is inserted into the vertical groove 281 .

[0082] When in use (when working), open the sealing cover 2, connect the cleaning liquid pipeline to the first water inlet 20 and the second water inlet 21 on the stator 181, and spray it out through the nozzle 44, and then drive the lifting screw 5 to move downward through the screw lift 4, thereby pushing the slip ring assembly 18 to move downward, and the spiral groove 63 in the rotor 182 cooperates with the spiral guide rail 11 on the drive shaft 10, so that the rotor 182 rotates while moving downward, thereby driving the frame to rotate, and the multiple cleaning rollers 13 on the frame clean the circumferential inner wall of the tank body 1 in a spiral motion.

[0083] The screw lift 4 includes a lift motor and a lift nut. The lift nut is rotatably connected to the tank body 1. The lift screw 5 is threadedly connected to the lift nut. A worm gear is coaxially fixedly connected to the lift nut. A worm that meshes with the worm gear is mounted on the output shaft of the lift motor. The lift motor drives the lift nut to rotate, thereby driving the lift screw 5 up and down.

[0084] When the frame reaches the lower end inside the tank body 1, the spiral groove 63 disengages from the spiral guide rail 11, and at the same time the guide block 59 is inserted into the vertical groove 281 on the arc block 28 below the rotor 182. At this time, the driving gear 50 on the rotating shaft 49 engages with the rack 60, thereby driving the cleaning brush 14 to flip 90° and unfold to the maximum drooping height, that is, the telescopic rod 47 is in a vertical state. At this time, the cleaning brush 14 contacts the inner wall of the bottom end of the tank body 1, and then the reduction motor 3 is started to drive the drive shaft 10 to rotate, so as to drive the rotor 182 to rotate, and then drive the cleaning brush 14 to rotate to clean the inner wall of the bottom end of the tank body 1.

[0085] The present invention also provides a method for using a self-cleaning enamel reactor, which is applicable to the above-mentioned self-cleaning enamel reactor and comprises the following steps:

[0086] Step 1: Open the sealing cover 2 of the tank body 1, rotate the first winding assembly 54 and the second winding assembly 55, and adjust the position of the sliding rod 395 to adjust the contact pressure between the cleaning roller 13 and the inner wall of the tank body 1;

[0087] Step 2: Connect the cleaning liquid pipeline to the first water inlet 20 and the second water inlet 21, and input the cleaning liquid;

[0088] Step 3: Start the screw lift 4 to drive the frame downward;

[0089] Step 4: When the frame moves down to the bottom, that is, the guide block 59 is completely inserted into the vertical slot 281, the screw lift 4 is closed, and the reduction motor 3 is started to drive the drive shaft 10 to rotate;

[0090] Step 5: Stop the reduction motor 3, reverse the screw lift 4, and drive the frame to move upward;

[0091] Step 6. Repeat steps 3 to 5 3 to 5 times;

[0092] Step seven: rinse the frame, cleaning roller 13 and cleaning brush 14. When the cleaning brush 14 is seriously contaminated, replace the cleaning brush 14.
