Description

TECHNICAL FIELD

[0001] The utility model relates to the field of mixing tooth, especially a kind of mixing tooth for wet powder heat exchange. BACKGROUND

[0002] At present, coal processing is ground into powder, and moisture exists in the powder, which forms wet powder. In order to keep the wet powder dry without residual moisture, a drying device is used for heat exchange drying. In order to ensure the uniformity of the wet powder during drying, a stirring shaft and a mixing tooth are used to stir the wet powder. The existing mixing tooth and stirring shaft are connected by welding. The stirring tooth includes a tooth plate and a bracket, and the bracket and the tooth plate are also connected by welding. In long-term use, the tooth plate and the bracket of the stirring tooth may be excessively worn, stressed and bent. At this time, the tooth plate and the bracket need to be replaced or repaired. However, because of the welding connection, the tooth plate and the bracket cannot be separated independently. After cutting, they need to be re-welded, which makes the maintenance of the stirring tooth very inconvenient.

[0003] To solve the above problems, we propose a mixing tooth for wet powder heat exchange. SUMMARY

[0004] The utility model aims to provide a mixing tooth for wet powder heat exchange, which has the advantage of being able to separate the tooth plate and the bracket independently.

[0005] The above technical purpose of the utility model is achieved by the following technical scheme: a mixing tooth for wet powder heat exchange, comprising an inner fixing ring, a bracket and a tooth plate, three clamping grooves are formed in the inner wall of the inner fixing ring, a clamping block integrally machined with the bracket is clamped in the inner clamping groove, a positioning bolt threaded with the inner fixing ring is connected in the inner bracket, a limiting groove clamped with the tooth plate is formed in the side of the bracket close to the tooth plate, two limiting blocks are integrally machined on one side of the tooth plate, and a limiting bolt threaded with the bracket is connected in the inner limiting block.

[0006] By setting the inner fixing ring, the bracket, the clamping groove, the clamping block and the positioning bolt, the bracket can be disassembled independently. By setting the tooth plate, the limiting block, the bracket and the limiting bolt, the tooth plate can be disassembled independently.

[0007] The utility model is further provided as follows: the number of inner fixing rings is two, and the two inner fixing rings are symmetrically arranged.

[0008] The inside of the two inner fixing rings can be sleeved on the surface of the stirring shaft, and the two inner fixing rings and the stirring shaft can be fixed by welding, and the clamping block can be attached to the stirring shaft and slide up and down without being connected to the inner fixing ring by the positioning bolt.

[0009] The utility model further sets up: the number of support is six, every two support is a group, and every group of support is symmetrically set up.

[0010] The two supports of each group need to be clamped with a toothed plate, and the toothed plate is integrally machined with two limiting blocks on one side and is screw-connected with the limiting bolts, so that the toothed plate and the two supports can be fixed.

[0011] The utility model further sets up: the number of toothed plate is three, and the toothed plate is located between the two supports.

[0012] The length of the toothed plate can be set to different lengths according to production, but the upper and lower end sizes of the toothed plate need to be matched with the limiting grooves, so as to facilitate clamping with the two supports.

[0013] The utility model further sets up: one side of the clamping block is arc-shaped.

[0014] After the three clamping blocks and the three clamping grooves in the inner wall of the inner fixing ring are clamped correspondingly, the inner wall of the inner fixing ring and one side of the three clamping blocks form a circular ring that can be attached to the stirring shaft.

[0015] In summary, the utility model has the following beneficial effects:

[0016] The clamping block is clamped with the clamping groove, the clamping block and the support are fixed by the positioning bolt, the inner fixing ring and the support are designed in sections, the support can be disassembled independently after the inner fixing ring and the stirring shaft are welded;

[0017] The two limiting blocks are fixedly connected on one side of the toothed plate, the limiting bolts are screw-connected in the two limiting blocks respectively, the two limiting blocks and the two supports are fixed by the two limiting bolts, and the toothed plate can be disassembled independently by clamping the top and bottom ends of the toothed plate with the two supports.

[0018] When the support or the toothed plate needs to be maintained, the utility model can be disassembled independently, the excessively worn parts can be replaced, and the deformed parts can be repaired, and after disassembly, the remaining supports and toothed plates can still be used.

[0026] Further, the number of inner fixing ring 1 is two, two inner fixing rings 1 are symmetrically arranged, the inside of two inner fixing rings 1 can be sleeved on the surface of stirring shaft, two inner fixing rings 1 and stirring shaft can be fixed by welding, clamping block 5 is not welded during welding process, clamping block 5 can be ensured to be attached to stirring shaft and slide up and down without being connected with inner fixing ring 1 by positioning bolt 6.

[0027] Further, the number of the support 2 is six, every two supports 2 is a group, every group of supports 2 is symmetrically arranged, and the toothed plate 3 is needed between the two supports 2 of each group. The two limiting blocks 8 integrally processed on one side of the toothed plate 3 are threadedly connected with the limiting bolt 9, so that the toothed plate 3 and the two supports 2 can be fixed.

[0028] Further, the number of the toothed plate 3 is three, the toothed plate 3 is located between the two supports 2, and the length of the toothed plate 3 can be set to different lengths according to production, but the upper and lower end sizes of the toothed plate 3 are matched with the limiting groove 7, so that the toothed plate 3 can be clamped with the two supports 2.

[0029] Further, one side of the clamping block 5 is arc-shaped, and after the three clamping blocks 5 are correspondingly clamped with the three clamping grooves 4 formed in the inner wall of the inner fixing ring 1, the inner wall of the inner fixing ring 1 and one side of the three clamping blocks 5 form a circular ring that can be attached to the stirring shaft.

[0030] Brief use process: when in use, first, the clamping block 5 on one side of the three supports 2 is clamped with the three clamping grooves 4 in the inner wall of the inner fixing ring 1, and then the three supports 2 and the inner fixing ring 1 are fixed by threadedly connecting the three supports 2 and the inner fixing ring 1 through the three positioning bolts 6; after that, another inner fixing ring 1 and three supports 2 are installed.

[0031] Then, one end of the three toothed plates 3 is clamped with the three limiting grooves 7 formed in the three supports 2, respectively, and the limiting block 8 is connected and fixed with the support 2 by using the corresponding number of limiting bolts 9.

[0032] Then, the other fixedly connected inner fixing ring 1 and the three supports 2 are installed.

When the support 2 is damaged, the limiting bolt 9 corresponding to the damaged support 2 and the inner fixing ring 1 are separated, and then the positioning bolt 6 corresponding to the damaged support 2 is separated. At this time, the clamping block 5 on one side of the damaged support 2 can be separated from the clamping groove 4 by sliding on the surface of the stirring shaft. At this time, the support 2 can be removed, and the supports 2 and the toothed plates 3 that are not operated can continue to be used. When installing, the clamping block 5 on one side of the support 2 is attached to the wall of the stirring shaft, is slid into the inside of the clamping groove 4, and the positioning bolt 6 and the limiting bolt 9 are installed again.

[0036] And according to the above-mentioned dismounting support 2, the dismounting of the tooth plate 3 connected therewith only needs to dismount the limiting bolt 9 connecting the other limiting block 8 and the support 2, and then the tooth plate 3 can be extracted and removed.

[0037] In summary, the supports 2 and the tooth plates 3 of the mixing teeth can be dismounted individually.
