[0002] Reactors are widely used in petroleum, chemical industry, rubber, pesticides, dyes, medicines, and foods. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, and condensation.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included. Example

[0032] Reference Figure 1~Figure 2 , which is the first embodiment of the present invention, provides a stainless steel reactor inner wall grinding device, the device includes a support unit 100, including two groups of symmetrically distributed workbenches 101, a roller 102 arranged on the inner side of the workbench 101, a drive motor 103 connected to one end of the roller 102, and three groups of clamping components 104 arranged on one side of the workbench 101; there is a space between the two groups of workbenches 101, which is used to provide a channel for the grinding unit 300 to move, the roller 102 is rotatably connected to the inner side of the workbench 101, and its horizontal height is flush with the upper surface of the workbench 101, and multiple groups of rollers are fixedly arranged on the roller 102, and the drive motor 103 can drive the roller 102 to rotate.

[0033] The adjusting unit 200 includes an adjusting component 201 vertically arranged at the lower inner side of the workbench 101, an adjusting component 202 horizontally arranged at one end of the workbench 101, and the end of the adjusting component 201 is meshed with the inner end of the adjusting component 202, and is threadedly connected to a moving block 203 on the adjusting 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 adjusting components 201, which are respectively arranged at the lower inner sides of two groups of workbenches 101, and each group of adjusting components 201 is provided with a moving block 203, the difference is that one group of adjusting components 201 is provided with threads, and the other group is smooth on the outside, wherein the adjusting component 201 with threads is threadedly connected to the moving block 203 sleeved thereon, and the other group of smooth adjusting components 201 is slidably connected to the corresponding moving block 203, and, The grinding unit 300 includes an arc frame 301 located between two groups of workbenches 101, a cross bar 302 disposed at the axis position of the arc frame 301, and the cross bar 302 extends horizontally to one end of the arc frame 301, a grinding component 303 disposed at the other end of the arc frame 301, an indicating component 304 disposed at one end of the arc frame 301 connected to the cross bar 302, and a fixing component 305 disposed vertically at the axis position of one end of the cross bar 302, and the fixing component 305 extends outward to one group of workbenches 101. The end of the cross bar 302 connected to the arc frame 301 is the outer end, and the inner end is located at the axis position of the arc frame 301. The two groups of 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 is rotatably connected to the two groups of moving blocks 203.

[0034] During use, the reactor to be polished is fixed on the workbench 101 by the clamping component 104, and the position of the polishing unit 300 is adjusted by driving the adjusting component 201 through the adjusting component 202. Then, the arc frame 301 is flipped over, and the polishing component 303 is pressed against a point of the weld to be polished. Then, the roller 102 is driven to rotate by the driving motor 103. Due to the gravity of the reactor to be polished and the coordinated limiting clamping of the clamping component 104, the reactor to be polished can rotate on the supporting unit 100, and the weld to be polished on the rotating reactor will make a circular motion at the polishing component 303, thereby realizing the overall polishing of the weld. Example

[0035] Reference Figure 2~Figure 3 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: according to the length of the reactor to be polished, the position of the polishing unit 300 can be adjusted by the adjustment unit 200, so that the polishing unit 300 can achieve the function of adaptive adjustment according to the specifications of the reactor, meet more usage requirements, and can directly locate the position of the weld to be polished on the inner wall of the reactor from the outside, without reaching into the reactor to perform additional weld position confirmation work, saving working time and improving work efficiency.

[0036] Compared with Example 1, further, the workbench 101 includes a table plate 101a located on one side of the roller 102, a limiting slide groove 101b opened in the table plate 101a, and the fixing component 305 extends into the limiting slide groove 101b, and a support leg 101c is arranged under the table plate 101a for support.

[0037] Among them, the outer end of the limiting slide groove 101b is opened upward, and the knob 305c extends upward through this opening to the top of the platform 101a, and a first bevel gear 102a is provided at one end of the roller shaft 102 close to the driving motor 103, and a second bevel gear 103a is provided at one end of the driving motor 103 close to the roller shaft 102, and the first bevel gear 102a is meshed with the second bevel gear 103a.

[0038] Among them, the clamping component 104 includes a cylinder 104a vertically arranged on the outside of the workbench 101, a clamping plate 104b horizontally arranged on the top of the cylinder 104a, and the clamping plate 104b extends to just above the middle position of the two groups of workbenches 101, a receiving groove 104c opened in the clamping plate 104b, a ball 104d arranged in the receiving groove 104c, and a support spring 104e located above the ball 104d and between the inner top surface of the receiving groove 104c.

[0039] Furthermore, the receiving groove 104c is opened in an inverted cone shape and opens downward to communicate with the outside. Since the diameter of the opening of the receiving groove 104c is slightly smaller than the diameter of the ball 104d, the ball 104d is rotatably engaged at the opening of the receiving 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 located below, and does not affect the circular rotation of the reactor.

[0040] During use, the reactor to be welded is placed on the support unit 100, and the lower sides of the reactor will rest against the rollers 102 due to their own gravity. The clamping component 104 located on the outside of 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 102 to rotate, and the rotating roller 102 can drive the reactor to rotate in a circle, and the reactor drives the weld to rotate, thereby facilitating the grinding component 303 that remains stationary to perform all-round grinding on the weld.

[0041] Among them, the adjustment component 201 includes an adjustment shaft 201a arranged at the lower inner side of the table 101a, and the moving block 203 is threadedly connected to the adjustment shaft 201a, and a third bevel gear 201b is arranged at the outer end of the adjustment shaft 201a, and the third bevel gear 201b is meshed and rotated with the outer end of the adjustment component 202, and the adjustment shaft 201a is rotatably connected to the bottom of the table 101a.

[0042] Among them, the adjusting component 202 includes two sets of fixed sleeves 202a fixedly connected to the outside of one end of the table plate 101a, a connecting shaft 202b arranged on the two sets of fixed sleeves 202a, a fourth bevel gear 202c arranged at the end of the connecting shaft 202b, and the fourth bevel gear 202c is meshed with the third bevel gear 201b, and a hand-cranked wheel 202d arranged at the outer end of the connecting shaft 202b.

[0043] During use, the third bevel gear 201b is rotatably connected to the axial position of the two sets of fixed sleeves 202a, and the connecting shaft 202b can be driven to rotate through the hand-cranked wheel 202d, and the rotating connecting shaft 202b can drive the adjusting shaft 201a to rotate through the engagement of the fourth bevel gear 202c and the third bevel gear 201b, and the moving block 203 is threadedly connected to the adjusting shaft 201a, and the two sides of the moving block 203 are limited by the workbench 101, so the moving block 203 can drive the grinding unit 300 to move as a whole in the space between the two sets of workbenches 101, and the moving grinding unit 300 can achieve the function of adjusting its own position according to the lateral depth of the weld on the inner wall of the reactor.

[0044] The remaining structures are the same as those of Example 1. Example

[0045] Reference Figure 4~Figure 10 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that it can perform inner wall weld grinding operations at different depths on reactors of different specifications, has wider flexibility and application range, and can meet more usage requirements.

[0046] Compared with Example 2, further, the arc frame 301 is a half-circular ring structure with an opening facing upward, one end of the cross bar 302 is located at the center of the arc frame 301, and the cross bar 302 extends laterally outward from the center of the arc frame 301, and the extension length is the same as the radius of the arc frame 301, and the outer end of the cross bar 302 is fixedly connected to one end of the arc frame 301.

[0047] During use, the arc frame 301 can rotate with the limiting axis 305a as the axis, and its motion trajectory is called motion trajectory Y. Figure 4 It can be seen that the grinding component 303 can reach the welds on the motion track Y by rotating the arc frame 301, so all welds on the motion track Y can be ground by the grinding component 303; The straight-line distance from the indicating part 304 to the grinding part 303 is equal to the diameter of the arc frame 301. This diameter is called diameter Z. As can be seen from the figure, as long as the horizontal straight-line distance between the weld to be welded and the opening of the reactor is within the diameter Z, the grinding part 303 can reach it by rotating the arc frame 301, so that the welding seams of different depths in the reactor can be ground. The distance of the grinding unit 300 can be adjusted by cooperating with the adjusting unit 200, and the grinding range of the grinding part 303 can be further adjusted to meet more usage requirements. Combination Figure 4The straight-line distance from the crossbar 302 to the limit axis 305a is the radius R, and the radius R is also on the motion trajectory Y. When the bottom of the reactor is attached to the workbench 101, as long as the diameter of the inner wall of the reactor is not less than R, it will not hinder the arc frame 301 from driving the grinding component 303 to extend into the reactor for grinding.

[0048] Among them, the grinding component 303 includes a connecting shaft 303a fixedly connected to one end of the arc frame 301, a rotating seat 303b rotatably connected to the top of the connecting 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, and the two ends of the elastic support rods 303d are respectively rotatably connected to the lower edge of the rotating seat 303b and the two sides of the outer end of the arc frame 301.

[0049] During use, the top of the connecting shaft 303a is a spherical structure, extending into the rotating seat 303b, and a corresponding matching rotating groove 303e is opened in the rotating seat 303b. The rotating groove 303e has a trumpet-shaped opening and is set downward. The trumpet-shaped structure allows the rotating seat 303b to rotate at multiple angles around the connecting shaft 303a. When the grinding wheel 303c abuts against the reactor weld, the reactor weld will squeeze the grinding wheel 303c. At this time, the elastic support rod 303d will shrink accordingly, so that the grinding wheel 303c is always attached to the weld in a parallel manner, effectively ensuring the grinding effect.

[0050] The indicating component 304 includes an indicating block 304a disposed at the other end of the arc frame 301, and a return spring 304b disposed below the indicating block 304a. The arc frame 301 has a corresponding spring slot 301a below the indicating block 304a, and the bottom of the indicating block 304a extends to the spring slot 301a.

[0051] During use, in the reactor composed of two parts, after the welding is completed, welds will exist on both the inside and outside of the reactor at the same time, and the two groups of welds are on the same horizontal line, and the two groups of welds are concentric and coaxial. The top of the indicator block 304a is an arrow structure, which is always extended above the outside of the arc frame 301 through the elastic support of the reset spring 304b, and can fit the outer wall of the reactor to be polished. By sliding along the outer wall of the reactor to the position of the outer wall weld, the position of the external weld and the position of the internal weld are on the same vertical horizontal line, and the indicator component 304 indicates on the external weld. At this time, the external weld and the internal weld are both on the motion trajectory Y of the arc frame 301 rotating along the limit axis 305a as the axis. At this time, the arc frame 301 rotates with the limit axis 305a as the axis, and the polishing component 303 can be moved to abut against the weld on the inner wall to be polished. Therefore, the indicator component 304 can serve the purpose of intuitively judging the depth and position of the weld.

[0052] Among them, the fixing component 305 includes a limiting shaft 305a arranged at the axial center position of the arc frame 301, and the limiting shaft 305a is coaxial with the arc frame 301, a fixing box 305b is arranged at one end of the limiting shaft 305a, and one end of the limiting shaft 305a extends into the fixing box 305b, a knob 305c is vertically arranged in the fixing box 305b, and the lower part of the knob 305c extends into the fixing box 305b, a worm 305d with a spiral structure is arranged at the part of the knob 305c extending to the outside of the fixing box 305b, a gear 305e is arranged on one end of the limiting shaft 305a extending into the fixing box 305b, and the gear 305e is meshed with the worm 305d.

[0053] During use, the limit shaft 305a extends into the limit slide groove 101b, and is limited in the vertical direction by the connecting shaft 202b, and can only slide horizontally along the limit slide groove 101b, while the knob 305c is fixedly connected to the worm 305d, the limit shaft 305a is fixedly connected to the gear 305e, and the limit shaft 305a is fixedly connected to the cross bar 302, and the cross bar 302 is fixedly connected to the arc frame 301, thereby deriving that the rotation of the knob 305c can drive the worm 305d to mesh and rotate with the gear 305e (such as Fig. 9 As shown), the arc frame 301 is driven to rotate with the limiting axis 305a as the axis, and the rotating arc frame 301 can achieve the function of driving the grinding component 303 to approach and abut against the weld (as shown in FIG. Fig.10 as shown).

[0054] The remaining structure is the same as that of Example 2.
