A slurry mixing reactor for polyester production

Abstract

The invention provides a slurry mixing reactor for polyester production, which relates to the technical field of reactors and includes a power motor, a front section of a barrel, a middle section of the barrel, a rear section of the barrel, a support plate, a rotating shaft, and the like; a support plate There are two. The top of the front support plate is connected with a barrel front section, the top of the rear support plate is connected with a barrel rear section, and a barrel middle section is connected between the barrel front section and the barrel rear section. A first installation frame is fixed in the middle of the rear wall of the support plate, and a power motor is installed in the first installation frame. In the present invention, the second sliding rod is linked with the triangular inclined block, and the raw materials in the feeding barrel are fed into the reaction kettle intermittently, and the function of intermittent feeding is realized without turning off the motor; the cylinder pushes the L-shaped sliding rod The second sliding frame is driven to slide down, and at the same time, the first sliding block is driven to slide out from the bottom of the middle section of the barrel body, exposing the through hole at the bottom of the middle section of the barrel body, which is convenient for taking materials.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to a slurry mixing reactor for polyester production. Background technique [0002] In polyester production, there is a process of mixing acid and alcohol in a certain proportion through a metering device. This mixing is that solid raw materials and liquid raw materials are mixed in a certain proportion with catalyst in a slurry tank. [0003] At present, the machine is directly stirred in the reactor during stirring, which is inconvenient to add raw materials in the middle, and it may be necessary to stop the machine when adding raw materials. When the machine is stopped, sedimentation is likely to occur, so that the stirring parts are immersed in the sedimentation layer. When restarting, there will be a lot of resistance, and the equipment itself will be damaged, and it is very time-consuming to remove the sediment in the reactor. When adding raw materials, manual intermittent fee...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a slurry mixing reactor for polyester production, to solve the problem that the current stirring is made by a machine directly in the reactor, which is inconvenient to add raw materials midway, and It may be necessary to stop the machine when adding raw materials, and it is prone to sedimentation when it is stopped. The type stirring parts are submerged in the sedimentation layer, and will be subjected to great resistance when restarting, and the equipment itself will be damaged. When adding raw materials, it is very time-consuming, and manual intermittent feeding is required when adding raw materials, which is very troublesome, and it is difficult to observe whether the reaction of the stirring material is completed when stirring in the reactor
