Detailed Description

With reference to fig. 1 to 3, a specific embodiment of the present invention is described in detail, but the present invention is not limited to the claims.

As shown in figures 1 to 3, a stirring and feeding device based on liquid level adjustment comprises a stirring kettle 1, wherein the bottom of the stirring kettle 1 is hemispherical, the stirring kettle with the hemispherical bottom can ensure complete evacuation of liquid without forming a large amount of residues, the upper end of the stirring kettle 1 is provided with a feeding pipe 1-1, the lower end of the stirring kettle 1 is provided with a discharging pipe 1-2, the feeding pipe 1-1 is positioned at a position close to the edge of the upper surface of the stirring kettle 1, the discharging pipe 1-2 is positioned at the lowest end of the stirring kettle 1, the inner wall of the stirring kettle 1 is vertically provided with two sliding chutes 1-3, a stirring shaft 2 is vertically arranged in the stirring kettle 1 through the two sliding chutes 1-3, the two sliding chutes 1-3 are symmetrically arranged on the stirring shaft 2, and a port at the lower end of the stirring shaft 2 is fixed with stirring blades 2-1 through positioning pins, the upper end of the stirring shaft 2 penetrates out of the stirring kettle 1 and is connected with a stirring motor 4, a continuous thread is arranged on the shaft body of the stirring shaft 2, a lifting block 3 is adjusted through the thread, and connecting blocks 3-2 connected with the sliding grooves 1-3 are arranged on two sides of the lifting block 3; during the use process, firstly, the aqueous solution of NaOH is put into the stirring kettle through the feeding pipe, and then bisphenol A or other bisphenol monomers are added into the stirring kettle through the feeding pipe; the motor adopts a reversible motor, the motor is started, the motor drives the stirring to rotate, the stirring blade at the bottom rotates along with the stirring shaft, the stirring shaft is ensured to drive liquid to flow at the bottom of the reaction liquid, and meanwhile, the stirring shaft and the lifting block form a screw rod rotation principle, so that the lifting block can be ensured to move up and down along the sliding chute; in the positive rotation process of the motor, the lifting block moves downwards under the pushing of the rotation of the stirring shaft, and when the motor rotates reversely, the lifting block moves upwards, so that in the use process, the lifting block continuously circulates in the ascending and descending process, and based on the fact that the lifting block descends, the space of the reaction solution is extruded, and the liquid ascends from the space between the lifting block and the inner wall of the stirring kettle; in the rising process of the lifting block, the liquid level falls and the lifting block is filled in a vacant way, so that the liquid level is lifted; based on the up-and-down movement of the lifting block, the liquid level is adjusted to be changed in a lifting way, and meanwhile, the directional rotation of the stirring blades achieves the effect of full mixing.

Furthermore, the stirring blade 2-1 is composed of a positioning rod 2-11 and two blades 2-12, a through hole is formed in the center of the positioning rod 2-11 and used for fixing the stirring blade on the stirring shaft through a positioning pin, the blades 2-12 are fixed at two ends of the positioning rod 2-11 respectively, each blade is in an oval shape, in the using process, the positioning rod serves as a connecting rod of the two blades to form a good connecting effect, the stirring blades are integrated, and meanwhile the through hole in the positioning rod can facilitate the fixing of the stirring blade through the positioning pin.
