Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and embodiments, it being understood that the specific embodiments described herein are only for the purpose of explaining the present invention and are not intended to limit the present invention.

Example 1

The embodiment provides a high-efficient dissolving tank of tympanic bulla formula, this dissolving tank is used for dissolving of industrial chemicals, especially, adopt the solid raw materials that conventional mechanical stirring mode is difficult to dissolve fast, as shown in fig. 1, fig. 2 shows, this dissolving tank includes cell body 1, bottom at cell body 1 is equipped with drain 101, be equipped with the valve on the drain 101, cell body 1 bottom inboard is equipped with sparger 2, be used for producing the bubble in order to accelerate the solution rate, sparger 2 includes main line 201 and a plurality of branch pipe 202, main line 201 is L shape, main line 201's vertical end accesss to cell body 1 outside, be used for connecting the compressed gas source, main line 201's horizontal end is located cell body 1's bottom, main line 201's horizontal segment is equipped with a plurality of branch pipes 202, be equipped with a plurality of gas pockets 203 on the branch pipe 202, gas pocket 203 is used for discharging the compressed gas.

The compressed gas source can be a pipeline for conveying compressed air or compressed nitrogen, and can also be an air compressor, and the specific pressure of the compressed gas is recommended to be between 0.15 and 1 MPa.

One side inner wall of the main pipeline 201 close to the tank body 1, the branch pipes 202 are uniformly arranged on the main pipeline 201, the number of the branch pipes can be any value of 4-12, in the embodiment, the number of the branch pipes is 8, the number of the air holes 203 in each branch pipe 202 is not less than 8, and in the embodiment, the number of the air holes 203 is 8.
