Description

Technical Field

[0001] The utility model relates to the technical field of sludge backfilling agent production, in particular to sludge backfilling agent stirring equipment. Background Art

[0002] Papermaking backfill agent, also known as sludge backfill agent, is a new type of inorganic polymer water purifier synthesized on the basis of polyferric phosphate sulfate and polyferric aluminum sulfate. The application of sludge backfill agent is to separate the same liquid, without reducing the quality and physical indicators of paper, thereby reducing production costs and alleviating environmental pressure. Sludge backfill agent needs to be mixed with a stirring piece during preparation.

[0003] Since the sludge backfill agent is in a semi-fluid state, in the process of production and processing, in order to stir quickly and efficiently, it is usually necessary to mix the sludge backfill agent. During the stirring process, the semi-fluid sludge backfill agent will rotate with the rotation of the stirring shaft. The continuous rotation of the stirring shaft will cause part of the semi-fluid to approach the stirring shaft and move with the stirring shaft, causing the entire stirring box to shake severely, affecting the safety of stirring. Usually, an external reinforcement structure is required to support the stirring box. For this reason, we propose a sludge backfill agent stirring equipment. Utility Model Content

The setting of the counterweight 7 on the outside of the balancing shaft 6 can complete the balance of the mixing shaft 4 and ensure the stability of the mixing shaft 4 during use. At the same time, the setting of the two outer limiting wheels 5 can support the balancing shaft 6 and limit the movement trajectory of the balancing shaft 6 during use. The inner limiting wheel 3 can limit the movement trajectory of the mixing shaft 4. A counterweight 7 is fixed to the outside of the balancing shaft 6 near the bottom end. A connecting short rod 9 is fixedly connected to the top of the two balancing shafts 6. A connecting long rod 8 is fixedly connected to the top of the two mixing shafts 4. The setting of the connecting long rod 8 and the connecting short rod 9 plays the role of connecting the two mixing shafts 4 and the balancing shaft 6 respectively, so that the balancing shaft 6 can be used to balance the mixing shaft 4 to ensure the stability of the equipment operation.

[0021] The outer fixed sleeve of the outer balance box 2 is provided with a support ring 12, the lifting ring 14 and the support ring 12 are parallel up and down, and the telescopic columns 13 are evenly distributed between the lifting ring 14 and the support ring 12.

The telescopic columns 13 can be used to control the position of the lifting ring 14, and then the position of the drive motor 15 can be controlled. After the drive motor 15 and the upper limit block 11 are separated, the upper limit block 11 and the lower limit block 10 are disassembled, and the stirring shaft 4 or the balancing shaft 6 can be replaced.
