Problems solved by technology

[0004] Although the stirred tank mixer has a long history of use and a wide range of applications, there are still obvious deficiencies in the stirred tank mixer, such as high equipment cost and energy consumption, and the sealing device is easily damaged due to high force and leaks. The replacement of the sealing device will reduce the effective Production time, uneven temperature and concentration distribution of materials in the kettle

Embodiment 1

[0022] Non-stirring mixing device, including mixing tank 1, circulation pump 2, circulation pipeline 3, chemical filler spoiler pipe 4, inlet for mixture material, outlet for mixture material and various accessories, and inlet fluid is fixed in mixing tank 1. The distributor 5 is a horizontal ring pipe with circular holes and four vertical pipes that are connected to each other. The outlet fluid drainage pipe is fixed in the mixing kettle 1 and the 6 is a plug-in pipe. The part that is inserted into the kettle is evenly opened with four supply pipes. Fluids at different heights in the kettle enter the axially long gaps therein; the guide baffle 7 fixed in the mixing kettle 1 is a flat plate arranged at an angle of 45 degrees to the cylinder wall of the mixing kettle 1. The two materials participate in the mixing. Material A is in front of the circulating pump 2 and the material B is in front of the spoiler pipe 4, and enters the spoiler pipe 4 in proportion, flows while mixing i...

Embodiment 2

[0025] The difference between the second embodiment and the first embodiment is that the spoiler tube 4 is a commercially available static mixer.

Embodiment 3

[0027] The third embodiment is different from the first embodiment in that the guide baffle 7 fixed in the mixing kettle 1 is a curved plate.

Abstract

The non-stirring mixing device relates to a chemical process production device. The non-stirring mixing device includes a mixing kettle (1), a circulating pump (2), a circulating pipeline (3), a spoiler tube (4), connecting pipelines and various accessories . The mixing kettle (1) is fixed with an inlet fluid distributor (5), an outlet fluid drainage pipe (6) and a diversion baffle (7); part or all of the circulation pipeline (3) is replaced by a spoiler pipe (4), The turbulence pipe (4) is an empty pipe or a mixing element with chemical filler or a disturbance effect on the fluid. The present invention provides the use method of the mixing device without stirring. The non-stirring mixing device proposed by the invention has low cost, low energy consumption, good mixing effect, maintenance-free, and long average annual effective production time. It can be widely used in the physical process and chemical reaction process in chemical production, replacing the traditional mechanical stirring tank type mixer, significantly improving production efficiency.

Description

technical field [0001] The invention relates to a chemical production device, in particular to a non-stirring mixing device replacing a mechanical stirring tank mixer. technical background [0002] Mixing is the process of dispersing two or more different substances between each other to achieve uniformity. Common mixing operations are mostly mechanical stirring. There are also airflow stirring or jet stirring to achieve mixing, but compared with mechanical stirring, the application is less. A device that mixes materials by mechanical stirring is called a stirred tank mixer. The stirred tank mixer has a wide range of applications. In the chemical industry, whether it is the production of bulk chemical raw materials or fine chemicals, mechanical mixing and mixing operations are widely used. Other industries such as petroleum, pharmaceuticals, pesticides, dyes, paints, fertilizers, etc. , are also widely used mechanical mixing operation. Stirring can promote the disturbanc...
