Counter-rotating bladeless stirring device and method

Abstract

The invention relates to a counter-rotating bladeless stirring device and a method, which are suitable for use in the field of coal chemical industry. The counter-rotating bladeless stirring device includes a cylinder body of a columnar structure and a stirring and mixing device, wherein a discharge port of a funnel structure is arranged below the cylinder body, three vertical baffles are evenly distributed on the inner wall surface of the cylinder body, and the top of the cylinder body is provided with a feeding port and a dosing port; the mixing and stirring device includes a lower distribution ring and an upper distribution ring arranged outside the cylinder body in a surrounding mode, wherein the lower distribution ring and the upper distribution ring are connected through a tee jointwhere a feed port is provided, the feed port and the discharge port are connected to each other by a pipe, and the pipe is provided with a pump for pressurization; the discharge port is further provided with a taking port, a plurality of lower feed pipes are arranged between the lower distribution ring and the cylinder body, and a plurality of upper feed pipes are arranged between the upper distribution ring and the cylinder body. The counter-rotating bladeless stirring device has the advantages of simple structure, convenient use, convenient installation and maintenance, low cost and good stirring effect, and has no need of a stirring device, since stirring and mixing can be realized by just using pressurized slurry per self to agitate and disturb the flow field.

Description

technical field [0001] The invention relates to a stirring device and method, in particular to a counter-rotating bladeless stirring device and method used in the field of coal chemical industry. Background technique [0002] Stirring device is a necessary equipment in the pulp treatment process, and the stirring effect has an important influence on the flotation of pulp. The traditional effective stirring method is mechanical stirring, but the structure of the mechanical stirring device is relatively complicated, the installation is difficult, and it is easy to wear and corrode. Due to the existence of wearing parts such as rotating mechanisms in mechanical stirring, structures such as seals are easily damaged during operation, and need to be stopped for maintenance and replacement on a regular basis. The continuous and stable operation of the device cannot be achieved, resulting in high maintenance and operation costs. Contents of the invention [0003] Technical proble...
