[0023] Embodiment: A device for cleaning the inner wall of a reaction vessel

[0024] Many existing tank cleaning equipment can only use flushing, which is mainly due to the interference of the central stirring structure. However, this example makes use of the central stirring structure to turn the obstacle into a boost.

[0025] The main structure includes a strip outer frame 1, the cross-section of which is a rectangle, and a mounting groove 2 passing through both ends of the strip outer frame 1 is provided on the bottom surface of the strip outer frame 1, and both ends of the mounting groove 2 pass through the end surfaces of the strip outer frame 1, and a blocking strip 3 extending along the direction of the opening is provided at the bottom notch of the mounting groove 2, which is used to limit the internal components so that the internal strip inner frame 11 can slide in the mounting groove 2 to adjust the position.

[0026] One end of the strip outer frame 1 is provided with a detachable clamping member, the clamping member includes an insert rod 5, one end of the insert rod 5 is provided with a matching female hoop 6 and a sub-hoop 7, the female hoop 6 is fixed to one end of the insert rod 5, an arc groove is centrally provided on the end face of the female hoop 6 away from the insert rod 5, the arc groove is adapted to the diameter of the matching stirring shaft, the two sides of the arc groove are respectively provided with fastening bolts 8 threadedly connected with the female hoop 6, one end of the sub-hoop 7 is also provided with an arc groove, the two sides of the arc groove are respectively provided with bolt holes for passing the sub-hoop 7, when the fastening bolt 8 passes through the bolt hole and is threadedly connected with the female hoop 6, the arc groove on the sub-hoop 7 and the arc groove on the female hoop 6 are relatively symmetrically arranged, forming a clamping and fixing of the stirring shaft, so that the device is matched on the stirring shaft. The outer end of the bolt is provided with a sinking groove for sinking the screw head of the fastening bolt 8.

[0027] The cross-section of the insertion rod 5 is adapted to the cross-section of the mounting groove 2, and the end of the insertion rod 5 away from the mother hoop 6 is inserted into one end of the mounting groove 2. A plurality of first positioning holes 4 are equidistantly arranged on the side wall of the strip outer frame 1 close to the clamping member. An inner screw hole 10 is provided at the edge of the end of the insertion rod 5 away from the mother hoop 6. A butterfly-shaped first positioning bolt 9 is threadedly engaged with the inner screw hole 10. The first positioning bolt 9 is movably connected with the first positioning hole 4. By inserting the first positioning holes 4 at different positions and then cooperating with the inner screw hole 10 on the insertion rod 5, the insertion depth of the insertion rod 5 relative to one end of the strip outer frame 1 can be adjusted.

[0028] Based on the above convenient disassembly relationship, the clamping parts of the cleaning device can be quickly replaced and adjusted, so as to adapt to the stirring shaft of the equipment being cleaned. At the same time, structures such as rubber washers can be added in the arc groove to increase the tightness of the assembly and protect the shaft.

[0029] The strip outer frame 1 is sleeved with a strip inner frame 11 that can slide along its length direction. The cross-sectional size of the strip inner frame 11 is adapted to the cross-sectional size of the mounting groove 2. The strip inner frame 11 is located at one end of the strip outer frame 1 away from the clamping member. The end of the strip outer frame 1 away from the clamping member is defined as the outer end, and the outer end of the strip inner frame 11 passes through the mounting groove 2 and is exposed outside the strip outer frame 1. A row of multiple equidistant second positioning holes 12 are provided on the side wall of the strip inner frame 11. An outer screw hole is provided at the edge position of one end of the strip outer frame 1 away from the clamping member. A second positioning bolt 13 is threadedly connected to the outer screw hole. The second positioning bolt 13 is also a butterfly bolt for convenient rotation. After the second positioning bolt 13 is threadedly connected to the outer screw hole and passed through, it is movably plugged or threadedly connected to the second positioning hole 12 on the strip inner frame 11. The second positioning hole 12 can be a plain hole or a threaded hole. The length of the outer end of the strip inner frame 11 extending out of the strip inner frame 11 is adjusted and positioned, and the expansion and contraction amount of the strip inner frame relative to the strip outer frame 1 is adjustable.

[0030] The strip inner frame 11 is provided with a sliding cavity 14 along its length direction. The end of the sliding cavity 14 away from the strip outer frame 1 is provided with a strip member 15 that cooperates with the strip outer frame 1 in telescopic sliding. The strip member 15 is a long strip with a cross section adapted to the sliding cavity 14. The end of the sliding cavity 14 located in the strip outer frame 1 is a closed structure and penetrated with an adjusting screw 16 threadedly connected thereto. The end of the strip member 15 close to the adjusting screw 16 is provided with a spring seat. The inner end of the adjusting screw 16 is also provided with a spring seat. There is a spiral compression spring between the two ends of the compression spring, and the two ends of the compression spring are respectively fixed on the two spring seats. The compression spring has an elastic force that makes the sliding bar away from the adjusting screw 16. The outer end of the sliding cavity 14 is provided with a clearance opening 17 that penetrates the strip inner frame 11 up and down. The width of the clearance opening 17 is adapted to the strip member 15, so as to make room for the position of the straight frame 23 of the strip member 15 during elastic telescopic movement.

[0031] The strip 15 is exposed in the sliding cavity, and one end outside the sliding cavity 14 is provided with a hinge seat 18 extending downward, and the bottom end of the hinge seat 18 is hingedly connected to a straight frame 23, and the hinge seat 18 is hingedly connected to the strip frame at one side edge close to the strip 15. The bottom surface of the strip 15 is provided with a strip groove 19 in the center, and a push cylinder 20 is hinged in the strip groove 19. The bottom end of the push cylinder 20 is telescopically matched with a push rod 21, and the push cylinder 20 can be an electric push cylinder 20, a hydraulic cylinder or a pneumatic cylinder. The bottom end of the push rod 21 is hingedly connected to the straight frame 23 and the hinge position is located below the hinge seat 18. Based on the telescopic movement of the push rod 21, the straight frame 23 can be driven to have a swing stroke from perpendicular to the strip 15 to parallel to the strip 15.

[0032] The bottom surface of the strip inner frame 11 is provided with a strip opening 22 communicating with the sliding cavity 14 . The strip opening 22 is used to expose the strip groove 19 and facilitate the swinging of the push rod 21 and the push cylinder 20 .

[0033] Since the mating position cannot be too close to the tank top, the hinge of the straight frame 23 is 30 cm away from its top, so that when the straight frame 23 is swung to a vertical state, it is possible to estimate the brushing of a certain distance above the hinge position.

[0034] A brush plate 24 is fixed to the straight frame 23 at one side away from the hinge seat 18 , and a brushing structure such as a sponge or bristles is fixed to the brush plate 24 .

[0035] Through the above structure, the method of using the device is:

[0036] The clamping member is fixed on the central shaft of the stirring structure inside the tank body, and the entire device is driven to rotate in the tank through the rotation function of the shaft itself.

[0037] After fixing, the brush plate 24 is made to stand upright by the push rod 21, so that the outer bristles can act on the inner wall of the tank.

[0038] The expansion and contraction amount of the strip inner frame 11 and the strip outer frame 1 can be adjusted by the second positioning bolt 13 , so as to adapt to the size of the tank body.

[0039] Based on the elastic expansion of the strip 15 at the outer end of the strip inner frame 11, the brush plate 24 can be pressed against the tank wall with a certain pressure and elasticity by compressing the spring. The pressing force of the spring can be adjusted by adjusting the screw 16, so as to adjust the size of the elastic pressure and realize the adjustment of the brushing force, which can be increased for the inner wall that is difficult to clean and reduced for the inner wall that is easy to clean.

[0040] The straight frame 23 and the strip outer frame 1 can be folded into a bundle, or can be unfolded to be vertical. When folded, it is convenient to enter and exit the equipment through the manhole, and when unfolded, it can realize the working state of brushing.

[0041] When the tank body is very high, the clamping parts and the central axis can be disassembled for multiple times and fixed at different heights respectively to realize the brushing of the inner walls at different heights.

[0042] The clamping part can be disassembled and replaced with a model that is compatible with the container stirring shaft, and has strong versatility.

[0043] Not limited to the above example, the hinge between the straight frame 23 and the strip 15 can also be supported without the push rod 21. After the top of the straight frame 23 is hinged to the hinge seat 18, under the action of gravity, when the strip outer frame 1 is fixed in a horizontal state, the straight frame 23 will naturally fall to a vertical state due to gravity. It is just that the pressure effect of sticking to the wall is slightly worse than that of the design with the push rod 21, but it can also achieve brushing. However, the processing cost and use conditions are greatly reduced.
