[0029] like Figure 2 and Figure 3 As shown in the embodiment of this utility model, a quick disassembly and sealing device for a spiral mixer includes a spiral mixer bracket, a reducer bracket, and a sealing assembly connected in sequence, wherein:

[0030] The spiral mixer support is fixedly installed on the side wall of the container. It includes a reinforcing plate 9, a connecting pipe 8 and a reinforcing rib 7. The reinforcing plate 9 is fixedly connected to the side wall of the container. The connecting pipe 8 is perpendicular to and fixed on the side wall of the container. The reinforcing rib 7 is perpendicular to the surface of the connecting pipe 8 and fixed between the reinforcing plate 9 and the connecting pipe 8 to enhance the connection stability between the side wall of the container and the connecting pipe 8.

[0031] The reducer bracket is fixedly installed between the spiral mixer bracket and the reducer 2. It includes a base plate 5 and a reducer mounting plate 3. The base plate 5 is detachably connected to the spiral mixer bracket. One side of the reducer mounting plate 3 is detachably connected to the base of the reducer 2, and the other side is fixedly connected to the base plate 5.

[0032] The sealing assembly is fixedly installed inside the reducer bracket. It includes a stuffing box 17, a stuffing gland 14, and a packing 16. The stuffing box 17 is fixedly connected to the base plate 5. The stuffing gland 14 is located on the side of the stuffing box 17 away from the container side wall and is detachably connected to the stuffing box 17. The packing 16 is placed inside the stuffing box 17.

[0033] This utility model sets the spiral mixer on the reducer bracket. By disassembling and assembling the base plate 5 set on the spiral mixer bracket, the reducer bracket and the spiral mixer bracket can be disassembled and assembled, thereby realizing the overall quick disassembly and assembly of the spiral mixer and improving the disassembly and maintenance process of the side-entry spiral mixer when there is residual material in the container.

[0034] Furthermore, the device also includes a motor 1, which is connected to the input end of the reducer 2 to drive the reducer 2 to rotate the stirring mechanism. The motor 1 can be connected to the reducer 2 via a flange, chain drive, coupling, gears, etc. This application does not specify a particular connection method.

[0035] Furthermore, the packing gland 14 is detachably connected to the packing housing 17 via gland bolts 15. Preferably, multiple gland bolts 15 can be provided to further secure the packing gland 14, preventing the gland bolts 15 from loosening due to the rotational vibration of the shaft head 13 during the operation of the screw mixer, thus preventing the packing 16 or the packing gland 14 from falling off. When it is necessary to replace the packing 16, the operator can loosen the gland bolts 15, remove the packing gland 14, and directly replace the packing 16 inside the packing housing 17.

[0036] Preferably, the filler 16 can be asbestos fabric, rubber, flexible graphite, and engineering plastics, etc. It can be selected according to specific working conditions and requirements, and this application does not impose specific limitations.

[0037] In one embodiment, the reinforcing plate 9 is annular and is used to reinforce openings on the sidewall of the container. The inner diameter of the reinforcing plate 9 is larger than the inner diameter of the connecting pipe 8.

[0038] In one embodiment, the device further includes a stirring mechanism, comprising a shaft head 13, a round steel bar 11, and a spiral blade 10 connected in sequence, wherein:

[0039] The spiral blade 10 is disposed inside the container. One end of the round steel 11 passes through the side wall of the container and is fixedly connected to the spiral blade 10. One end of the shaft head 13 passes through the sealing assembly and the connecting pipe 8 in sequence and is detachably connected to the end of the round steel 11 away from the side wall of the container. The other end is detachably connected to the reducer 2.

[0040] Furthermore, the shaft head 13 is detachably connected to the round steel 11 via a first flange 12. The diameters of the first flange 12, the round steel 11, and the spiral blade 10 are all smaller than the inner diameter of the connecting pipe 8. This ensures that the first flange 12, the round steel 11, and the spiral blade 10 can all pass through the connecting pipe 8, further guaranteeing that when disassembling the base plate 5 of the reducer bracket from the spiral mixer bracket, the round steel 11 and the spiral blade 10 can be simultaneously removed from or placed into the container.

[0041] When installing the spiral mixer on the side wall of the container, first connect the spiral blade 10, round steel 11 and first flange 12 as a whole to the shaft head 13. Then, pass the shaft head 13 through the reducer bracket and the stuffing box 16, put the packing 16 into the stuffing box 17, tighten the cover bolts 15 to fix the packing cover 14, then connect the reducer bracket to the spiral mixer bracket through the second flange 6, and finally fix the reducer 2 on the reducer mounting plate 3 and connect the reducer and shaft head 13. At this point, the entire device installation is complete.

[0042] When disassembling the spiral mixer from the side wall of the container, remove the base plate 5 from the spiral mixer bracket, and then directly remove the reducer 2, the mixing mechanism, the reducer bracket and the sealing assembly. Then, disassemble the reducer 2, the sealing assembly and the mixing mechanism in sequence.

[0043] In one embodiment, at least two reinforcing ribs 7 are provided to further enhance the connection stability between the container sidewall and the nozzle 8.

[0044] The number of reinforcing ribs 7 can be determined according to the perimeter of the pipe 8. For example, if one reinforcing rib 7 is set every 10 cm, then 10 reinforcing ribs 7 should be set when the perimeter of the pipe 8 is 100 cm.

[0045] It is understood that this application does not specify the number of reinforcing ribs or how the reinforcing ribs are arranged.

[0046] In one embodiment, the reducer bracket has an open structure. The sealing assembly is located inside the reducer bracket. When the packing 16 needs to be replaced, the operator can loosen the gland bolts 15 through the open opening of the reducer bracket to remove the packing gland 14 and directly replace the packing 16 inside the packing housing 17. This improves the efficiency of replacing the packing 16 and avoids the problem of needing to disassemble the mixer 2 when replacing the packing 16.

[0047] Furthermore, the base plate 5 is fixedly connected to the reducer mounting plate 3 by multiple support rods 4 and / or multiple support plates.

[0048] When designing the reducer bracket, to facilitate the replacement of the packing 16 in the internal sealing components of the reducer bracket by operators, the reducer mounting plate 3 and the base plate 5 can be connected using only support rods 4, making the reducer bracket a frame structure. In this case, operators can remove and install the packing gland 14 and replace the packing 16 through the gaps between two adjacent support rods 4 from various directions. Alternatively, support plates can be used to connect the reducer mounting plate 3 and the base plate 5, making the reducer bracket a box-frame structure. In this case, operators can remove and install the packing gland 14 and replace the packing 16 through the openings in the box-frame structure. Furthermore, support rods 4 and support plates can be used simultaneously to connect the reducer mounting plate 3 and the base plate 5. For example, support rods can be installed at the openings in the box-frame structure, which not only reinforces the reducer bracket but also ensures that operators can remove and install the packing gland 14 and replace the packing 16 through the gaps between two adjacent support rods 4 on the connecting surface. Alternatively, support plates can be used to replace support rods 4 on some sides of the frame structure. In this case, operators can remove and install the packing gland 14 and replace the packing 16 through the gaps between two adjacent support rods 4 on other connecting surfaces. It is understood that this application does not impose specific limitations on how the gearbox bracket is designed.

[0049] In one embodiment, the base plate 5 is detachably connected to the connecting pipe 8 in the screw mixer bracket via a second flange 6. This facilitates the disassembly of the reducer bracket while ensuring the stability of the connection between the reducer bracket and the screw mixer bracket.

[0050] Furthermore, such as Figure 4 As shown, both the base plate 5 and the second flange 6 are machined with fine-textured water lines. These water lines are located on the connection surface of the base plate 5 and the second flange 6. The fine-textured water lines increase the friction between the flange sealing surface and the gasket, improving the flange's sealing performance and effectively preventing media leakage from the connection point.

[0051] Numerous specific details are set forth in the specification provided herein. However, it will be understood that embodiments of the present invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

[0052] Furthermore, those skilled in the art will understand that although some embodiments described herein include certain features but not others included in other embodiments, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0053] Those skilled in the art will understand that although the present invention has been described with reference to exemplary embodiments, various changes may be made and its elements may be replaced with equivalents without departing from the scope of the present invention. Furthermore, many modifications may be made to adapt particular situations or materials to the teachings of the present invention without departing from the essential scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed, but rather will include all embodiments falling within the scope of the appended claims.
