Description

Technical Field

[0001] The utility model relates to the technical field of dispersing and stirring devices, in particular to a high-speed dispersing and stirring device for preparing water-based resin adhesive. Background Art

[0002] The production of water-based adhesives is synthesized by free radical polymerization of comonomers in an intermittent reactor, and the low-boiling monomers in the comonomers are in a reflux state at the reaction temperature. After the low-boiling monomers condensed by the condenser are refluxed into the reactor, they need to be evenly dispersed into the reaction system as soon as possible to prevent the self-polymerization of the refluxed monomers. The self-polymerization of the refluxed monomers is a side reaction in the reaction system, which causes the reaction system to produce resin particles and lumps that cannot be dispersed in water, and causes the product copolymer composition to be unstable and the yield to be reduced. For this reason, the production and synthesis of water-based adhesives requires that the surface materials of the liquid surface in the reactor can move quickly and quickly disperse into the reaction system below the liquid surface in the reactor.

[0003] There are various types of common reaction kettles for preparing resin adhesives. The patent with application number CN202022254804.8 discloses a resin adhesive mixer, which is provided with a base, a mounting plate, an arc plate, a stirring barrel, a stirring motor, a stirring shaft, a stirring rod, a mounting rod, a mounting chamber, a buffer spring, a cross bar and other structures. The stirring shaft and several stirring rods are driven by a motor to rotate to achieve dispersion and stirring of various materials. However, the stirring rods provided therein can only rotate at a horizontal height, and it takes a long time to rotate to fully disperse and mix the various materials, resulting in an increase in stirring time and a relatively low stirring efficiency. For this reason, we propose a high-speed dispersing and stirring device for preparing water-based resin adhesives to solve the above problems. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a high-speed dispersing and stirring device for preparing a water-based resin adhesive, which solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a high-speed dispersing and stirring device for preparing water-based resin adhesives, comprising a dispersing reactor, a sealing top cover is fixedly installed on the top of the dispersing reactor by bolts, and a driving motor is fixedly installed on the top of the sealing top cover, a discharge valve pipe is arranged in the middle of the bottom end of the dispersing reactor, and a supporting leg is arranged on the circumference of the discharge valve pipe at the bottom of the dispersing reactor, a transmission shaft is fixedly connected to the output shaft of the driving motor, and a stirring shaft is sleeved on the outside of the transmission shaft, and a plurality of stirring blades are arranged on the outside of the stirring shaft, and the driving motor drives the transmission shaft to rotate, and drives the stirring through the connecting keyway transmission. The mixing shaft and the stirring blades rotate to disperse and stir the materials. The driving motor is a common existing technology, and its principle and use process are not elaborated here. Two sets of transmission components are arranged above the outside of the stirring shaft, and an adjustment seat cooperating with the transmission assembly is arranged at the end of the dispersion reactor. The middle part of the adjustment seat is movably sleeved on the outside of the stirring shaft to assist in positioning the top of the stirring shaft, and an adjustment slide is provided on the top of the adjustment seat. The stirring shaft synchronously drives the transmission assembly to rotate, and the position of the transmission assembly is limited by the adjustment slide on the adjustment seat, thereby driving the stirring shaft as a whole to move back and forth up and down. When the stirring blade stirs the material, the reaction is more intense, so that the material can be quickly and fully mixed.

[0006] Preferably, the stirring blades are evenly distributed on the outside of the stirring shaft. The stirring shaft drives several stirring blades to rotate, thereby stirring the material and achieving dispersed mixing of multiple materials. The inside of the stirring shaft and the outside of the transmission shaft are provided with mutually matching connecting key grooves, and the compression spring can apply elastic force to the stirring shaft to facilitate the resetting of the stirring shaft during operation.

[0007] Preferably, the external movable sleeve of the transmission shaft is provided with a compression spring, and the compression spring is located above the stirring shaft. The compression spring always applies elastic force to the stirring shaft. By applying elastic force to the stirring shaft through the compression spring, the stirring shaft can be reset downward, and can cooperate with the transmission assembly and the adjustment seat to drive the stirring shaft to move reciprocatingly up and down, so that the stirring shaft can withstand a higher rotation speed, thereby further improving work efficiency.

[0008] Preferably, the transmission assembly includes a transmission rod and a transmission roller. The transmission rod is fixedly connected to the stirring shaft, and the transmission roller is movably installed at the end of the transmission rod. When the stirring shaft rotates, the transmission assembly is driven to rotate synchronously.

[0009] Preferably, the adjusting slide is distributed in a wave shape as a whole, and the driving roller can roll on the top of the adjusting slide, so that the adjusting slide is set to a wave shape as a whole. When the driving roller rolls on the top of the adjusting slide, it can drive the stirring shaft to move back and forth up and down.

[0010] Preferably, a mounting bracket is fixedly installed on the peripheral side of the adjustment seat, and the mounting bracket is installed on the top of the dispersion reactor by bolts. When the sealing top cover is installed, the mounting bracket is synchronously installed between the top of the dispersion reactor and the sealing top cover by bolts to ensure the firmness of the mounting bracket and the adjustment seat during operation. The adjustment seat is movably mounted on the outside of the stirring shaft. When the stirring shaft is working, it can rotate stably inside the adjustment seat to ensure the stability of the stirring shaft during operation.

[0011] Preferably, a positioning assembly is provided at the lower part of the interior of the dispersion reactor, and the positioning assembly includes two groups of positioning rods and positioning tiles. The positioning rods are installed inside the dispersion reactor by screws to ensure stability during operation. One end of the positioning rod is fixedly connected to a positioning tile, and the positioning tile is clamped to the outside of the stirring shaft. The positioning assembly is configured as a split structure as a whole, which ensures the positioning of the stirring shaft while facilitating disassembly and assembly.

[0013] 1. The high-speed dispersing and stirring device for preparing water-based resin adhesive drives the transmission shaft to rotate through a driving motor, and drives the stirring shaft and stirring blades to rotate through a connecting keyway transmission to disperse and stir the materials. At the same time, the stirring shaft synchronously drives the transmission component to rotate, and the position of the transmission component is limited by an adjusting slide on an adjusting seat, thereby driving the stirring shaft to move back and forth up and down as a whole, so that the reaction is more intense when the stirring blade stirs the material, so that the material can be quickly and fully mixed, shortening the dispersion and stirring time and improving work efficiency.

[0014] 2. The high-speed dispersing and stirring device for preparing water-based resin adhesive has a middle movable sleeve of the adjusting seat mounted on the outside of the stirring shaft, which can assist in positioning the top of the stirring shaft, and assist in positioning the bottom of the stirring shaft through the positioning component to ensure the stability of the stirring shaft during rotation, so that the stirring shaft can withstand a higher rotation speed and further improve work efficiency.
