[0021] Through the above technical scheme, in the production process of polycarboxylate superplasticizer, the raw materials required for producing polycarboxylate superplasticizer are put into the reaction kettle 2, the stirring frame 14 can be moved to the appropriate position in the reaction kettle 2 through the displacement mechanism, and the sealing cover mechanism can ensure that the whole reaction kettle 2 is in a relatively sealed state, finally the motor 12 is started to make the stirring frame 14 stir the raw materials through the driving shaft 13, and the bubbles on the surface of the polycarboxylate superplasticizer are eliminated through the defoaming mechanism after production is completed.

[0022] Specifically, the sealing cover mechanism includes a penetrating shaft 6 fixedly penetrating in the inner side of the first kettle cover 4, the outer surface of the penetrating shaft 6 is rotatably connected with a screw rod 7, and the outer surface of the screw rod 7 is threadedly sleeved with a clamping rotary handle 8.

[0023] Through the above technical scheme, the outer surfaces of the first kettle cover 4 and the second kettle cover 5 are both provided with grooves, which can facilitate the screw rod 7 to be embedded therein, and the clamping rotary handle 8 cannot be embedded into the groove during the axial movement along the screw rod 7.

[0024] Specifically, the displacement mechanism includes a sliding rail 9 fixedly installed on the outer surface of the equipment body 1, the outer surface of the sliding rail 9 is slidably connected with a displacement frame 11, the inner surface of the displacement frame 11 is fixedly connected with the outer surface of the motor 12, the top of the equipment body 1 is fixedly installed with an air cylinder 10, and the output end of the air cylinder 10 is fixedly connected with the top of the displacement frame 11.

[0025] Through the technical scheme, the displacement frame 11 can be pushed and pulled by the air cylinder 10 to slide up and down along the slide rail 9, so as to change the position of the stirring frame 14 and the disc 15 in the reaction kettle 2.

[0026] Specifically, the defoaming mechanism comprises a disc 15 fixedly sleeved on the outer surface of the driving shaft 13, and the bottom of the disc 15 is provided with a plurality of piercing needles 16.

[0027] Through the technical scheme, the diameter of the disc 15 is basically the same as the inner diameter of the reaction kettle 2, and a plurality of piercing needles 16 are arranged on the bottom of the disc 15 in a relatively uniform manner, so that the piercing needles 16 can effectively puncture the bubbles when the bubbles are touched.

[0028] Specifically, the bottom of the disc 15 is fixedly connected with a collecting frame 17, and the bottom of the collecting frame 17 is provided with a water filtering hole 18.

[0029] Through the technical scheme, the collecting frame 17 is designed in cooperation with the filter screen 19 to cooperate with the piercing needles 16, and after the piercing needles 16 puncture a large number of bubbles, the collecting frame 17 cooperates with the filter screen 19 to collect and filter the remaining small bubbles.

[0030] Specifically, the inside of the collecting frame 17 is provided with a filter screen 19.

[0031] Through the technical scheme, the filter screen 19 is designed to allow the filter bubbles to adhere to the surface of the filter screen 19, and on the other hand, the filter screen 19 is designed to allow the bubbles to burst when passing through the mesh holes of the filter screen 19.

[0032] Working principle: when the device is in use, first, the raw materials needed for the production of polycarboxylic acid water reducing agent are put into the reaction kettle 2, then the air cylinder 10 is started to push the displacement frame 11, so that the displacement frame 11 slides down along the slide rail 9, and the position of the adjusting motor 12 and the lower stirring frame 14 and the disc 15 is adjusted until it is adjusted to the appropriate height (during this process, the first kettle cover 4 and the second kettle cover 5 are completely opened, so that the stirring frame 14 and the disc 15 can smoothly enter the reaction kettle 2, and the stirring frame 14 should be below the liquid level, and the disc 15 should be above the liquid level), then the first kettle cover 4 and the second kettle cover 5 are rotated along the hinge 3 until the two sets of kettle covers are combined at the end of the hinge 3, then the screw rod 7 is pushed along the shaft 6, so that it is embedded in the groove opened on the outer surface of the two sets of kettle covers, and finally the clamping knob 8 is screwed along the screw rod 7, until the clamping knob 8 moves axially along the screw rod 7 to tightly abut against the outer surface of the second kettle cover 5, so that the first kettle cover 4 and the second kettle cover 5 are in a stable and tightly connected state, that is, the polycarboxylic acid water reducing agent production process in the whole reaction kettle 2 is in a relatively sealed state, then the motor 12 is started to drive the driving shaft 13 to rotate, thereby driving the stirring frame 14 to stir the solution, and the disc 15 can effectively block the liquid from splashing up. Considering the strong bubble characteristics of polycarboxylic acid water reducing agent in the production process, after the stirring production is completed, there will be a large number of bubbles of different sizes on the surface, at this time the disc 15 can be moved up and down (near the solution surface) by the air cylinder 10, so that the contact between the lancet 16 and the bubbles can break them, and at the same time the motor 12 can be started to gradually change the rotating position of the disc 15, thereby changing the position of the lancet 16 to move up and down repeatedly to treat the solution surface. During the rotation of the disc 15, the collection frame 17 can "scrape" the bubbles at the liquid surface, so that a small amount of bubbles (mainly small bubbles) that have not been broken are collected in the collection frame 17, and the bubbles are filtered by the filter screen 19 to adhere to the filter screen 19. Finally, the polycarboxylic acid water reducing agent liquid in the collection frame 17 can be discharged from the filter hole 18, thereby efficiently eliminating the bubbles generated during the production of polycarboxylic acid water reducing agent.

[0033] Although embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the application, the scope of which is defined by the appended claims and their equivalents.
