Description

[0002] Reactors are widely used in the fields of petroleum, chemical industry, rubber, pesticides, dyes, pharmaceuticals, and food, and are pressure vessels used to complete process procedures such as vulcanization, nitrification, hydrogenation, alkylation, polymerization, and condensation. For reactors with a large volume, due to their large structure and difficulty in one-piece molding, in the actual production process, they are generally divided into multiple parts, and then each component is welded into a whole by welding.

[0003] At the same time, in order to improve the corrosion resistance, improve the surface finish, and enhance the tensile strength, the weld seams after welding will be polished. In the prior art, the inner wall weld seams of large-scale reactors are mostly polished slowly by artificial means using tools.

In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included. Embodiment

[0035] Referring to Figures 1 - 2 , for the first embodiment of the present invention, a polishing device for the inner wall of a stainless steel reactor is provided. This device includes a support unit 100, which includes two groups of symmetrically distributed workbenches 101, a roller shaft 102 disposed inside the workbench 101, a driving motor 103 connected to one end of the roller shaft 102, and three groups of clamping components 104 disposed on one side of the workbench 101; there is a space between the two workbenches 101 to provide a channel for the movement of the polishing unit 300. The roller shaft 102 is rotatably connected to the inside of the workbench 101, and its horizontal height is flush with the upper surface of the workbench 101. A plurality of rollers are fixedly provided on the roller shaft 102, and the driving motor 103 can drive the roller shaft 102 to rotate.

[0036] An adjustment unit 200, which includes an adjustment component 201 vertically disposed below the inside of the workbench 101, an adjustment part 202 horizontally disposed at one end of the workbench 101, and the end of the adjustment component 201 meshes with the inner end of the adjustment part 202. A moving block 203 is threadedly connected to the adjustment component 201, and one side of the moving block 203 abuts against the inner side surface of the workbench 101; there are two groups of adjustment components 201, which are respectively disposed below the inside of the two workbenches 101. A moving block 203 is provided on each group of adjustment components 201. The difference is that one group of adjustment components 201 has threads, and the other is smooth on the outside. The adjustment component 201 with threads is threadedly connected to the moving block 203 sleeved thereon, and the other smooth adjustment component 201 is slidably connected to the corresponding moving block 203. And,

[0037] The grinding unit 300 includes an arc-shaped frame 301 located between two groups of workbenches 101, a cross bar 302 disposed at the axial center position of the arc-shaped frame 301, and the cross bar 302 extends horizontally to one end of the arc-shaped frame 301. A grinding component 303 is disposed at the other end of the arc-shaped frame 301, an indicating component 304 is disposed at one end where the arc-shaped frame 301 is connected to the cross bar 302, and a fixing component 305 is vertically disposed at the axial center position of one end of the cross bar 302, and the fixing component 305 extends outward into one group of workbenches 101. The end of the cross bar 302 connected to the arc-shaped frame 301 is the outer end, and the position at the axial center position of the arc-shaped frame 301 is the inner end. Two moving blocks 203 are respectively located on both sides of the inner end of the cross bar 302, and the limiting shaft 305a connects the three in series, wherein the limiting shaft 305a is fixedly connected to the inner end of the cross bar 302 and rotatably connected to the two moving blocks 203.

[0038] During the use process, the reaction kettle to be ground is fixed on the workbench 101 through the clamping component 104. The position of the grinding unit 300 is adjusted by driving the adjustment assembly 201 through the adjustment component 202. Subsequently, the arc-shaped frame 301 is flipped, and the grinding component 303 is abutted against a point on the weld to be ground. Then, the roller shaft 102 is driven to rotate by the driving motor 103. Due to the self-gravity of the reaction kettle to be ground and the cooperative limiting clamping of the clamping component 104, the reaction kettle to be ground can rotate on its own on the support unit 100, and the weld to be ground on the rotating reaction kettle will perform a circular motion at the grinding component 303, thereby realizing the overall grinding of the weld. Embodiment

[0039] Refer to Figures 2 - 3 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that according to the length of the reaction kettle to be ground, the position of the grinding unit 300 can be adjusted by the adjustment unit 200, so that the grinding unit 300 has the function of adapting to the reaction kettle specifications, meeting more usage requirements, and being able to directly locate the position of the weld to be ground on the inner wall of the reaction kettle from the outside, without reaching into the reaction kettle interior for additional weld position confirmation work, saving working time and improving work efficiency.

[0040] Compared with Embodiment 1, further, the workbench 101 includes a table board 101a located on one side of the roller shaft 102, a limiting sliding groove 101b opened in the table board 101a, and the fixing component 305 extends into the limiting sliding groove 101b, and a support leg 101c disposed below the table board 101a for support.

[0041] Among them, the outer end of the limit chute 101b is upwardly open, the knob 305c extends upward through this opening to above the table board 101a, a first bevel gear 102a is arranged at one end of the roller shaft 102 close to the driving motor 103, a second bevel gear 103a is arranged at one end of the driving motor 103 close to the roller shaft 102, and the first bevel gear 102a meshes with the second bevel gear 103a.

[0042] Among them, the clamping member 104 includes a cylinder 104a vertically arranged outside the workbench 101, a clamping plate 104b horizontally arranged at the top end of the cylinder 104a, and the clamping plate 104b extends to directly above the middle position between the two groups of workbenches 101, a storage groove 104c opened in the clamping plate 104b, a ball 104d arranged in the storage groove 104c, and a support spring 104e located between the ball 104d and the inner top surface of the storage groove 104c above the ball 104d.

[0043] Furthermore, the storage groove 104c is opened in an inverted conical shape and communicates with the outside downward. Since the diameter of the opening of the storage groove 104c is slightly smaller than the diameter of the ball 104d, the ball 104d is rotationally clamped at the opening of the storage groove 104c, and the support spring 104e always pushes the ball 104d outward, so that the ball 104d first contacts the outer wall of the reactor below, and does not affect the circumferential rotation of the reactor.

[0044] During the use process, the reactor to be welded is placed on the support unit 100. The two sides below the reactor will be abutted against the roller shaft 102 under the influence of its own gravity. The clamping member 104 located outside the workbench 101 pushes the clamping plate 104b downward, and a downward clamping force can be applied to the reactor from above. The driving motor 103 drives the roller shaft 102 to rotate, and the rotating roller shaft 102 can drive the reactor to rotate circumferentially. The reactor drives the weld to rotate, thereby facilitating the all-round grinding treatment of the weld by the stationary grinding member 303.

[0045] Among them, the adjusting assembly 201 includes an adjusting shaft 201a arranged below the inner side of the table board 101a, and the moving block 203 is threadedly connected to the adjusting shaft 201a. A third bevel gear 201b is arranged at the outer end of the adjusting shaft 201a, and the third bevel gear 201b meshes and rotates with the outer end of the adjusting member 202. The adjusting shaft 201a is rotatably connected below the table board 101a.

[0046] Among them, the adjusting member 202 includes two fixing sleeves 202a fixedly connected to the outer side of one end of the table board 101a, a connecting shaft 202b arranged on the two fixing sleeves 202a, a fourth bevel gear 202c arranged at the end of the connecting shaft 202b, and the fourth bevel gear 202c meshes with the third bevel gear 201b, and a hand crank 202d arranged at the outer end of the connecting shaft 202b.

[0047] During use, the third bevel gear 201b is rotatably connected to the axial center positions of two fixed sleeves 202a. The connecting shaft 202b can be driven to rotate by the hand crank 202d. The rotating connecting shaft 202b can drive the adjusting shaft 201a to rotate through the meshing of the fourth bevel gear 202c and the third bevel gear 201b. The moving block 203 is threadedly connected to the adjusting shaft 201a, and both sides of the moving block 203 are limited by the workbench 101. Therefore, the moving block 203 can drive the entire grinding unit 300 to move within the space between the two workbenches 101. The moving grinding unit 300 can achieve the function of adjusting its own position according to the transverse depth of the weld on the inner wall of the reactor.

[0048] The remaining structures are the same as those in Embodiment 1. Embodiment

[0049] Referring to Figures 4 - 10 , this is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that it can perform grinding operations on the inner wall welds at different depth positions of reactors with different specifications, with greater flexibility and a wider scope of application, meeting more usage requirements.

[0050] Compared with Embodiment 2, further, the arc-shaped frame 301 is a semi-circular ring structure with an upward opening. One end of the cross bar 302 is located at the center of the arc-shaped frame 301. The cross bar 302 extends horizontally outward from the center of the arc-shaped frame 301, and the extended length is the same as the radius of the arc-shaped frame 301. The outer end of the cross bar 302 is fixedly connected to one end of the arc-shaped frame 301.

[0051] During use, the arc-shaped frame 301 can rotate around the limit shaft 305a as the axis, and its movement trajectory is called movement trajectory Y. From Figure 4 it can be seen that for the welds on the movement trajectory Y, the grinding component 303 can reach them by rotating the arc-shaped frame 301. Therefore, all the welds on the movement trajectory Y can be ground by the grinding component 303;

[0052] The straight-line distance from the indicating component 304 to the grinding component 303 is equal to the diameter of the arc-shaped frame 301. This diameter is called diameter Z. From the figure, it can be seen that for all the welds to be welded whose horizontal straight-line distance from the reactor opening is within the diameter Z, the grinding component 303 can reach them by rotating the arc-shaped frame 301. Therefore, the work of grinding the welds at different depths inside the reactor can be achieved. By further adjusting the distance of the grinding unit 300 in cooperation with the adjusting unit 200, the grinding range of the grinding component 303 can be further adjusted to meet more usage requirements;

[0053] Combined with Figure 4, the straight-line distance from the cross bar 302 to the limit shaft 305a is the radius R, and the radius R is also on the movement track Y. When the bottom of the reaction kettle is attached to the workbench 101, as long as the inner diameter of the reaction kettle is not less than R, it will not prevent the arc-shaped frame 301 from driving the grinding component 303 to extend into the reaction kettle for grinding work.

[0054] Among them, the grinding component 303 includes a connecting rotating shaft 303a fixedly connected to one end of the arc-shaped frame 301, a rotating seat 303b rotatably connected to the top of the connecting rotating shaft 303a, grinding wheels 303c symmetrically arranged on the front and rear sides of the rotating seat 303b, and elastic support rods 303d symmetrically arranged on the left and right sides below the rotating seat 303b. The two ends of the elastic support rod 303d are respectively rotatably connected to the lower edge of the rotating seat 303b and the outer ends on both sides of the arc-shaped frame 301.

[0055] During use, the top of the connecting rotating shaft 303a is a spherical structure and extends into the rotating seat 303b. A corresponding rotating groove 303e is opened in the rotating seat 303b. The rotating groove 303e has a flared opening downward. The flared structure enables the rotating seat 303b to rotate at multiple angles around the connecting rotating shaft 303a. When the grinding wheel 303c abuts against the weld of the reaction kettle, the weld of the reaction kettle will squeeze the grinding wheel 303c. At this time, the elastic support rod 303d will shrink accordingly, so that the grinding wheel 303c always fits on the weld in a parallel manner, effectively ensuring the grinding effect.

[0056] Among them, the indicating component 304 includes an indicating block 304a arranged at the other end of the arc-shaped frame 301, and a return spring 304b arranged below the indicating block 304a. A corresponding spring groove 301a is opened in the arc-shaped frame 301 below the indicating block 304a, and the lower part of the indicating block 304a extends into the spring groove 301a.

[0057] During use, inside the reaction kettle composed of two welded parts, after welding is completed, there will be welds on both the inner and outer sides, and the two groups of welds are on the same horizontal line and are concentric and coaxial. The top of the indicating block 304a is an arrow structure. Through the elastic support of the return spring 304b, it always extends above the outside of the arc-shaped frame 301 and can fit against the outer wall of the reaction kettle to be ground. By sliding along the outer wall of the reaction kettle to the position of the outer wall weld, at this time, the position of the outer weld and the inner weld are on the same horizontal line in the same vertical direction. The indicating component 304 indicates on the outer weld. At this time, both the outer weld and the inner weld are on the movement track Y where the arc-shaped frame 301 rotates around the limit shaft 305a as the axis. At this time, the arc-shaped frame 301 rotates around the limit shaft 305a as the axis, and the grinding component 303 can be moved to abut against the weld to be ground on the inner wall. Therefore, the indicating component 304 can serve the purpose of intuitively judging the depth and position of the weld.

[0058] Among them, the fixed part 305 includes a limiting shaft 305a arranged at the axial center position of the arc-shaped frame 301, and the limiting shaft 305a is coaxial with the arc-shaped frame 301. One end of the limiting shaft 305a is provided with a fixed box 305b, and one end of the limiting shaft 305a extends into the fixed box 305b. A knob 305c is vertically arranged in the fixed box 305b, and the lower part of the knob 305c extends into the fixed box 305b. A worm 305d with a spiral structure is arranged at the part where the knob 305c extends outside the fixed box 305b. A gear 305e is arranged at one end of the limiting shaft 305a extending into the fixed box 305b, and the gear 305e meshes with the worm 305d.

[0059] During the use process, the limiting shaft 305a extends into the limiting chute 101b and is limited in the vertical direction by the connecting shaft 202b, and can only perform horizontal translation sliding along the limiting chute 101b. The knob 305c is fixedly connected with the worm 305d, the limiting shaft 305a is fixedly connected with the gear 305e, the limiting shaft 305a is fixedly connected with the cross bar 302, and the cross bar 302 is fixedly connected with the arc-shaped frame 301. Thus, it can be deduced that when the knob 305c rotates, it can drive the worm 305d and the gear 305e to mesh and rotate (as Figure 9 shown), and then drive the arc-shaped frame 301 to rotate with the limiting shaft 305a as the axis. The rotating arc-shaped frame 301 can achieve the function of driving the grinding part 303 to approach and abut against the weld (as Figure 10 shown).

[0060] The remaining structures are the same as those in Embodiment 2.
