Description

Stable mixing device for nylon 6 slices Technical Field The utility model relates to the technical field of mixing equipment, in particular to a nylon 6 slice stable mixing device. Background In the production process of nylon 6 slices, the mixing is a key link for ensuring the uniformity of the product quality. At present, common compounding device adopts the structure of compounding jar cooperation stirring rake generally, realizes the mixture of material through mechanical stirring. However, in practical application, especially for nylon 6 slices with high density or easy stacking, the materials at the bottom of the mixing tank are easy to form a dead angle due to gravity deposition, so that the mixing is uneven. Although the traditional mixing device can realize the mixing of main materials through the stirring paddle, the structural design of the bottom of the tank body is single, an effective auxiliary fluidization means is lacked, and the slices at the bottom are difficult to fully stir, so that the overall mixing effect is influenced. In addition, some devices have attempted to solve this problem by increasing the stirring intensity or prolonging the mixing time, but this not only increases the energy consumption, but also may cause a decrease in the material properties due to excessive shearing. Therefore, there is a need for a stable nylon 6 slice mixing device that can optimize the fluidity of nylon 6 slices at the bottom of a mixing tank, improve the mixing uniformity of the nylon 6 slices, and simultaneously compromise the energy efficiency and the process stability. Disclosure of utility model The utility model aims to provide a nylon 6 slice stable mixing device which can optimize the fluidity of nylon 6 slices at the bottom of a mixing tank, improve the mixing uniformity of the nylon 6 slices and simultaneously consider the energy efficiency and the process stability. The utility model adopts the following technical scheme: The nylon 6 slice stable mixing device comprises a mixing tank, wherein a charging hole is formed in the top of the mixing tank, a guide table is formed in the bottom of the mixing tank in an upward extending mode, a discharge hole capable of being opened and closed is formed in the mixing tank on one side of the guide table, the guide table is in a round table shape, an air guide pipe communicated with an air pump is arranged in an inner cavity of the guide table, an air guide nozzle is arranged on the air guide pipe, a through hole for the installation of the air guide nozzle is formed in the guide table, and a mixing paddle driven by a motor is arranged in the mixing tank.
