Embodiment 1

[0022] In order to solve the problems of low mixing and dispersing efficiency and uneven mixing of materials, the present invention adopts an asymmetrical and reverse stirring shaft structure. The kettle is divided into two parts. One part is a kettle body (14) with a cylindrical inner cavity; the other part is an inner hollow kettle cover (2) connected with the transmission device (1). One group of oil inlet holes (10) and oil return holes (9) are arranged on the kettle cover (2), and these two holes communicate with the oil inlet through holes and the oil return through holes on the rotating wheel frame. The kettle cover (2) connects the inner ring gear (4) and the rotating wheel frame (7) through the bearing and the sealing device from top to bottom, and the rotating wheel frame (7) is evenly distributed under the rotating wheel frame (7). The three stirring shafts and one wall-cleaning shaft without heat medium are called the wall-cleaning shaft (33), the quadrangular pri...

Embodiment 2

[0030] Take one of the quadrangular prism stirring shaft 1 (18) and the quadrangular prism stirring shaft 2 (32) as an example to illustrate the rotation of the shaft and the sealing of the rotary oil seal.

[0031] The rotation of the stirring shaft is divided into two parts, one is revolution and the other is rotation. Revolution: when the input shaft of the mechanical transmission rotates, the rotating wheel frame connected to it rotates due to the action of the fixed "key", and then drives the stirring shaft and the cleaning shaft on the rotating wheel frame to rotate around the input shaft of the mechanical transmission. Autorotation: When the stirring shaft rotates around the input shaft of the mechanical transmission, the gear connected to the stirring shaft will rotate and shift relative to the ring gear it engages with. Since the inner ring gear is fixed on the lid of the kettle, the gear meshing with it begins to rotate along the ring gear, thereby realizing the self...

Abstract

The invention belongs to the technical field of heating and cooling stirring kettles, and particularly relates to a high-speed dispersion stirring kettle with an asymmetric, reverse and internal heating stirring shaft. The stirring kettle comprises a kettle cover, a kettle body, a stirring device, a heating constant-temperature oil tank, an oil pump, a temperature controller and the like, the kettle body adopts a double-layer jacket structure, an insulating layer is arranged outside the kettle body, a spiral coil is arranged in an interlayer from top to bottom along the kettle body to form a heating medium channel, and cold water is introduced into a gap formed by the spiral coil in the interlayer and the kettle wall to form a refrigerant channel. The stirring device is fixed in the kettle cover through a rotating wheel frame, and a bearing and a sealing device are arranged in the kettle cover. The stirring device is composed of three stirring shafts and one wall cleaning shaft which are evenly distributed in the rotating wheel frame, a high-speed rotating stirring shaft corresponds to the wall cleaning shaft in position, and the other two quadrangular stirring shafts correspond to each other in position. The high-speed rotating stirring shaft and the two quadrangular stirring shafts respectively perform revolution along with the rotating wheel frame and perform reverse autoroatation at the same time. According to the invention, an asymmetric and reverse stirring design is adopted, so that the problems of low mixing and dispersing efficiency and non-uniform mixing in the material mixing reaction process are solved.

Description

technical field [0001] The invention belongs to the technical field of heating and cooling stirring tanks, in particular to a high-speed dispersion stirring tank with asymmetrical, reverse and inner heating stirring shafts. Background technique [0002] The broad understanding of the stirred tank is a container for physical or chemical reactions. In production operations, it is necessary to stir and mix raw materials to accelerate chemical reactions and uniformity of materials. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling, exhaust and high and low speed mixing functions required by the process are realized. [0003] There are many kinds of stirring tanks at present, and they are also being continuously improved. For example, CN201920881118.8 is a heat-conducting oil heating stirring tank. Heat and stir to increase the physical and chemical reaction rate of the material inside the stirred tank. Another example...
