Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a polycarboxylate water-reducing agent production reaction kettle. Background Art

[0002] Water reducer is a concrete admixture that reduces the amount of water used in concrete mixing. When producing polycarboxylic acid water reducer, the raw materials of polycarboxylic acid water reducer need to be mixed, so a reactor is used to react the raw materials. For example, in the patent number "CN217940170U" and the patent name "A reactor for producing polycarboxylic acid water reducer", the heat insulation board is first placed inside the installation groove, and then the connecting block is connected to the reactor body with bolts. In the subsequent use process, the heat insulation sleeve and the heat insulation board can prevent the heat inside the reactor body from being transferred to the control switch, and the heat absorbing cotton can absorb the heat transferred to the heat insulation sleeve to prevent the heat from being transferred to the control switch, thereby preventing the control switch from being damaged and preventing subsequent staff from scalding accidents when using the control switch. However, the above structure still has the following problems in actual use:

[0003] Although the above reactor absorbs heat through heat-absorbing cotton to avoid scalding accidents when subsequent staff use the control switch, a large number of bubbles will be generated when the polycarboxylate water-reducing agent reacts in the reactor. The above reactor cannot eliminate the bubbles in time, resulting in a boiling kettle phenomenon when the polycarboxylate water-reducing agent reacts in the reactor.

[0004] Therefore, we proposed that the polycarboxylic acid water reducer production reactor can solve the above problems well. Utility Model Content
