Description

Technical Field

[0001] The invention relates to the technical field of chemical equipment, in particular to a lifting type vacuum disperser. Background Art

[0002] Disperser is a kind of mixer in a broad sense. Since the use of high-speed agitators (such as disc sawtooth agitators) can form strong turbulence locally, it usually has a strong dispersing and emulsifying effect on materials, so this type of high-speed agitator is also called a disperser. Most existing dispersers are fixed when in use, and can perform the process of stirring while lifting.

[0003] In view of this, the Chinese Patent Network published an invention patent with application number: 202421132116.6 and application name: A high-speed and powerful disperser on January 7, 2025, which specifically discloses "a high-speed and powerful disperser, including a fixed seat, a connecting assembly is installed below the fixed seat, the connecting assembly includes a rotating shaft, the upper end of the rotating shaft is movably connected to the inside of the fixed seat, and the lower end of the rotating shaft is provided with a square hole, and the inner side wall of the square hole is provided with a receiving groove, and the inner bottom of the receiving groove is fixedly connected with a spring, and one end of the spring is fixedly connected with a movable block. A connecting rod is provided at the lower end of the rotating shaft, and a connecting block is fixedly connected to the upper end of the connecting rod. The connecting block is located inside the square hole, and a movable groove is provided inside the connecting rod. A top block is provided inside the movable groove, and a lever is fixedly connected to the side surface of the top block, and a dispersion disk is fixedly connected to the lower end of the connecting rod. The present invention can replace different types of dispersion disks at any time according to the needs of use, which is quick and convenient, improves the practicality of the dispersion disk, and facilitates the use of the disperser."

[0004] There are also two problems in the use of the above scheme. The first is that the lifting device in the scheme adopts a unilateral lifting method. Since the fixed seat and the rotating motor are relatively heavy, they only rely on a screw in the mounting seat for limiting. When lifting during high-speed stirring, the entire disperser will shake due to unbalanced force, and the working noise is loud. In more serious cases, it will cause the barrel to lose balance and fall. It is only suitable for some small dispersers at medium and low speeds, and cannot meet the requirements of large dispersers working at high speeds for a long time; second, the scheme cannot create a vacuum environment for the barrel when working. Since the screw directly drives the fixed seat to move up and down, it indirectly drives the barrel cover to move up and down, so that the barrel cover will be repeatedly in an open and closed state, which cannot meet the requirements of some materials that need to be dispersed in a vacuum, high temperature and high pressure environment. Summary of the invention

[0005] The problem to be solved by the present invention is to provide a lifting vacuum disperser with simple structure, reasonable design, high stability, convenient use, high safety and good dispersing effect.

[0007] Preferably, in the above-mentioned lifting vacuum disperser, a heating jacket for heating the stirring cylinder is provided on the outer wall of the stirring cylinder.

[0008] Preferably, in the above-mentioned lifting vacuum disperser, the number of the stirring motors is 2, and the two stirring motors drive the stirring reducer simultaneously.

[0009] Preferably, in the above-mentioned lifting vacuum disperser, a base is provided at the bottom of the stirring cylinder, and the lifting motor and the lifting reducer are installed on the base.

[0012] Preferably, in the above-mentioned lifting vacuum disperser, rotary bearings are respectively installed at the upper and lower ends inside the support column, and the adapter shaft is embedded in the rotary bearings.

[0013] Preferably, in the above-mentioned lifting vacuum disperser, a plurality of lifting bearings are installed inside the column, and the lifting screw is embedded in the lifting bearings.

[0014] The advantages and beneficial effects of the present invention are as follows: (1) The present application uses two stirring motors arranged horizontally to jointly drive a stirring reducer to indirectly drive the stirring shaft to rotate, which not only has better structural stability, but also can increase the stirring force to meet the needs of high-speed stirring; (2) The present application uses two sets of columns and lifting columns in combination. Since the columns are fixed on the base and do not move, combined with the support columns and two sets of guide rods and guide sleeves, it is equivalent to achieving four-point limits in the vertical direction.

The lower end of the lifting screw A lifting gear is embedded and installed, and the driving gear is meshed with the lifting gear. When the lifting motor is controlled to work, the stirring shaft can be indirectly driven to rise and fall, so that the cross paddle can move up and down when rotating at high speed, so that the materials in the stirring tank can be mixed more fully and the dispersion effect is better; (4) By setting a vacuum pump, the stirring tank can be evacuated into a vacuum, which can not only remove the impurity gas, but also effectively avoid the chemical reaction between the impurity gas and the materials in the stirring tank to produce defective products, eliminate the influence of the gas on the reaction, ensure the accuracy and stability of the reaction, and have a certain explosion-proof effect; (5) The stirring shaft and the sealing cover in the present application are connected in a movable seal. When the stirring shaft moves up and down, the sealing cover is always covered on the stirring tank and will not move up and down with the stirring shaft. In this way, not only can the stirring tank be kept in a vacuum state, but also the stirring shaft can be controlled to move up and down while maintaining the vacuum state.
