Description

Technical Field

[0001] The utility model belongs to the technical field of packing chamber supports, and in particular relates to a support bracket for a stirring packing chamber of a filter. Background Art

[0002] Packing seal refers to a dynamic sealing device that generates a compressive force between the packing and the rotating parts and the fixed parts through the self-tightening effect of pre-tightening or medium pressure. It is also called "stuffing box seal". There are many structural forms, mainly composed of packing, stuffing box and packing fixed parts. Commonly used packing materials include asbestos fabric, carbon fiber, rubber, flexible graphite and engineering plastics, which are prefabricated into rings or strips (some need to be pre-impregnated with fillers with good lubricity) and adopt multi-ring or spiral multi-layer structure. During the stirring and rotation of the filter, the packing chamber will also swing with the stirring shaft.

[0003] However, the existing filter stirring packing chamber is often directly fixed on the bracket, and slight swing will occur during the rotation of the stirring shaft. The extrusion force acting on the packing when the stirring shaft swings increases the pressure of the packing on the shaft, resulting in severe heat and wear, which reduces the service life of the packing. Therefore, a filter stirring packing chamber support bracket is urgently needed to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of the utility model is to provide a support bracket for a stirring packing chamber of a filter, so as to solve the problem proposed in the above-mentioned background technology that the existing stirring packing chamber of a filter is often directly fixed on the bracket, and slight swing will occur during the rotation of the stirring shaft. When the stirring shaft swings, the extrusion force acting on the packing increases the pressure of the packing on the shaft, thereby causing serious heat and wear, thereby reducing the service life of the packing.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a filter stirring packing chamber support bracket, comprising a packing chamber, a stirring shaft, a pressure cover, a packing, a bottom bushing, a support structure and a vibration reduction structure, a bottom bushing is installed inside the front end of the packing chamber, a packing is installed inside the middle of the packing chamber, the packing is rotatably connected to the stirring shaft, the rear side of the packing chamber is installed, the left and right sides of the packing chamber are installed with support structures, and the bottom of the support structure is installed with a vibration reduction structure.

[0006] Preferably, the gland is slidably connected to a gland bolt, the gland bolt is fixedly connected to the rear side of the packing chamber, and the gland bolt is threadedly connected to a gland nut.

[0007] Preferably, the support structure comprises a support rod, a support seat and a limit plate, and the support rod is fixedly connected to the outer wall of the packing chamber.

[0008] Preferably, the support rod is slidably connected to the support seat, and the side of the support rod away from the packing chamber is fixedly connected to the limit plate.

[0009] Preferably, the vibration reduction structure comprises a fixing plate, a fixing block, a spring and a damper, and two fixing plates are provided.

[0010] Preferably, the fixing plate at the left end is fixedly connected to the support seat, and the fixing plate at the right end is fixedly connected to the limiting plate.

[0011] Preferably, the fixing plate is fixedly connected to two fixing blocks on one side close to the middle, a spring is installed between the left and right fixing blocks, and a damper is installed between the two fixing plates.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The support bracket of the stirring packing chamber of the filter is provided with a support structure. During the rotation of the stirring shaft, slight swing will occur. The support rod can move left and right in the movable hole of the support seat. The packing chamber will slightly displace together with the support rod, thereby offsetting the extrusion force acting on the packing when the stirring shaft swings, ensuring the sealing of the packing, extending the service life of the packing, eliminating the hidden danger of material leakage, reducing the labor intensity of maintenance personnel replacing the packing, and ensuring the normal operation of the equipment and stable production.

[0014] 2. The support bracket of the stirring packing chamber of the filter is provided with a vibration reduction structure, which can reduce the vibration of the packing chamber on the support seat, ensure the stability of the equipment, and can reset the packing chamber and the support rod when the stirring shaft stops rotating, so as to facilitate use.
