Problems solved by technology

Yet, the production of dispersant needs sufficient reaction time, and in microreactor and pipeline reactor, the residence time of reaction raw material is short, therefore, microreactor or pipeline reactor in the prior art is not suitable for the production of dispersant. Production; on the other hand, the production efficiency of microreactors and pipeline reactors is relatively low, which cannot meet the large-scale manufacturing needs of dispersants.
[0005] To sum up, there is a lack of a reaction kettle equipment with uniform feeding, high production efficiency, and suitable for the production and manufacture of dispersants in the prior art.

Embodiment 1

[0038] Example 1: Reference figure 1 A microporous reaction kettle shown includes a kettle body 100 , a feeding mechanism 200 , a stirring mechanism 300 , and a discharging mechanism 400 . Wherein, the stirring mechanism 300 adopts a lower driving type, that is, the stirring drive member 310 (such as a motor) is located below the kettle body 100; meanwhile, the kettle body 100 is based on any one of the kettle body structures in the prior art. The bottom of the body 100 is inclined; the discharge mechanism 400 is arranged on the bottom of the kettle body 100 on the basis of any discharge mechanism structure in the prior art (such as including a discharge pipeline, a buffer, a discharge pump, etc.) Tilt low to facilitate complete discharge.

[0039]The feeding mechanism 200 includes a first feeding pipeline 210, a second feeding pipeline 220, a feeding unit 230, an opening and closing unit 250 for closing or opening the feeding micropore 240, and a piston unit 260 arranged in ...

Embodiment 2

[0054] Embodiment 2: the difference between embodiment 2 and embodiment 1 is that, refer to Figure 6 and Figure 7 As shown, the feeding unit 230 includes a plurality of sub-feeding chambers 232 arranged independently of each other. For example, in this embodiment, it includes 4 sub-feeding chambers 232 of the same shape, and the 4 sub-feeding chambers 232 can be assembled into a round cake shape. The feeding unit 230. Each sub-feeding chamber 232 is respectively fixed to the lower part of the second feeding pipe 220 by welding, and the upper surface of the part located in the space of the second feeding pipe 220 is provided with openings.

[0055] The secondary feeding pipe 270 in this embodiment extends to communicate with the sub-feeding chamber 232 . Specifically, the number of secondary feeding pipes 270 is the same as that of the sub-feeding chambers 232, and they correspond one-to-one, and extend to the sub-feeding chambers 232 to communicate with the openings on the...

Embodiment 3

[0056] Embodiment 3: the difference between embodiment 3 and embodiment 1 is that, refer to Figure 8 and Figure 9 As shown, in this embodiment, the feeding unit 230 includes a main feeding chamber 231, a plurality of (for example, 4) sub-feeding chambers 232 communicated with the main feeding chamber 231 respectively, and the main feeding chamber 231 is round cake-shaped The upper surface of the hollow metal part can be relatively rotatably installed on the lower part of the second feeding pipe 220 through rolling bearings, and communicates with the second feeding pipe 220 . Its lower part has a concave platform, which is keyed to the stirring drive shaft 320 of the stirring mechanism 300 , so that the stirring drive shaft 320 can drive the main feeding chamber 231 . The sub-feeding chamber 232 is in the shape of a long rectangular hollow metal plate, one end of which is welded and fixed on the outer peripheral side wall of the main feeding chamber 231, and the sub-feeding ...

Abstract

The invention provides a microporous reaction kettle which comprises a kettle body, a material inlet mechanism, a stirring mechanism and a material outlet mechanism, wherein a stirring driving piece of the stirring mechanism is located below the kettle body; the material inlet mechanism comprises a first material inlet pipeline, a second material inlet pipeline, a hollowly structured feeding unithaving a plurality of feeding micropores, an opening and closing unit for closing or opening the feeding micropores, and a piston unit arranged in the second material inlet pipeline; the feeding unitis arranged at the lower part of the second material inlet pipeline, and is communicated with the second material inlet pipeline; in a recycling stroke, the piston unit closes the second material inlet pipeline and controls the opening and closing unit to close the feeding micropores; in a recycled state, the piston unit closes the second material inlet pipeline; in an extending stroke, the pistonunit closes the second material inlet pipeline and controls the opening and closing unit to open the feeding micropores. The microporous reaction kettle can avoid problems of too fast local reaction,fluctuation of the pH value and material aggregation, and is high in production efficiency.

Description

technical field [0001] The present application relates to the technical field of chemical preparation equipment, in particular to a microporous reactor. Background technique [0002] In the field of paper coatings, dispersants are an indispensable raw material for improving production efficiency and product quality. [0003] The traditional method of producing dispersants is to first feed the basic reaction raw materials into the reactor, and then drop other reaction raw materials in sequence or at the same time, and finally stir and react in the reactor. . When other reaction raw materials are dropped in, the droplets are relatively large, and react after contacting the basic reaction raw materials in the reactor, so local reactions are prone to rapid local pH fluctuations, resulting in local material agglomeration in the reactor , Stirring can not break up the problem. [0004] Microreactor and pipeline reactor are a new type of reaction vessel that can realize continuo...
