Abstract

The utility model discloses a tool for dismantling a bottom tile sleeve of a polymerization kettle, which comprises a blind plate, a screw rod, a mounting nut and a connecting bolt, wherein two first connecting holes corresponding to a polymerization kettle flange plate of the bottom tile sleeve are formed in the blind plate, the top end of the screw rod sequentially penetrates through the first connecting holes and through holes of the polymerization kettle flange plate and then is in threaded connection and fixation with a fixed seat at the bottom of the polymerization kettle, and the screw rod below the blind plate is in threaded connection with the mounting nut movably abutted with the blind plate; a plurality of second connecting holes corresponding to the stirring shaft flange plates of the bottom tile sleeve are formed in the blind plate between the two first connecting holes, and the connecting bolts penetrate through the second connecting holes and are then screwed into screw holes of the corresponding stirring shaft flange plates. The advantages are that: after the blind plate and the bottom tile sleeve are connected into a whole through the connecting bolts, the bottom tile sleeve can be detached by only applying downward force to the blind plate along the screw rod, so that the detachment efficiency is improved; meanwhile, the hidden danger caused by the fact that the bottom tile sleeve is manually removed or accidentally dropped is avoided.

Description

Tool for dismantling bottom tile sleeve of polymerization kettle

Technical field:

the utility model relates to the technical field of maintenance of a polymerization kettle, in particular to a tool for dismantling a bottom tile sleeve of the polymerization kettle.

The background technology is as follows:

the polymerization kettle is a main device for preparing high molecular compounds, is a vertical cylindrical autoclave and is provided with a jacket; the bottom tile sleeve for installing the stirring shaft is fixed at the bottom of the kettle body through bolts and comprises a polymerization kettle flange plate above and a stirring shaft flange plate below. However, in the actual production process, the material is found to be deposited at the bottom of the polymerization kettle and enters between the bottom tile and the stirring shaft on the inner wall of the bottom tile sleeve, so that the rotation of the stirring shaft can be influenced, and the stirring shaft can be locked and cannot rotate when serious, so that the bottom tile needs to be cleaned periodically. At present, manual dismantling is adopted, namely, a stirring shaft is firstly pulled out of a bottom tile, and then a bottom tile sleeve is knocked downwards until the bottom tile sleeve is dismantled from the bottom of a kettle body; however, because the material deposition at the bottom of the kettle body causes the difficulty in dismantling the bottom tile sleeve, the efficiency is low, and the bottom tile sleeve is easy to damage by directly knocking the bottom tile sleeve, so that the service life is influenced.

The utility model comprises the following steps:

the utility model aims to provide a tool for dismantling a bottom tile sleeve of a polymerization kettle, which can improve the dismantling efficiency.

The utility model is implemented by the following technical scheme: the tool for dismantling the bottom tile sleeve of the polymerization kettle comprises a blind plate, a screw rod, a mounting nut and a connecting bolt, wherein two first connecting holes corresponding to a flange plate of the polymerization kettle of the bottom tile sleeve are formed in the blind plate, the top end of the screw rod sequentially penetrates through the first connecting holes and through holes of the flange plate of the polymerization kettle and then is in threaded connection and fixation with a fixed seat at the bottom of the polymerization kettle, and the mounting nut movably abutted to the blind plate is in threaded connection with the screw rod below the blind plate; a plurality of second connecting holes corresponding to the stirring shaft flange plates of the bottom tile sleeve are formed in the blind plates between the two first connecting holes, the connecting bolts penetrate through the second connecting holes and then are screwed into the corresponding screw holes of the stirring shaft flange plates, and the nuts of the connecting bolts are clamped below the blind plates.

Further, a dismounting nut is screwed on the screw above the blind plate.

The utility model has the advantages that: after the blind plate and the bottom tile sleeve are connected into a whole through the connecting bolts, the bottom tile sleeve can be detached by only applying downward force to the blind plate along the screw rod, so that the detachment efficiency is improved; meanwhile, the hidden danger caused by the fact that the bottom tile sleeve is manually removed or accidentally dropped is avoided.
