Description

Technical Field

[0001] The present invention relates to the technical field of water reducing agents, and in particular to automated production equipment and a process for producing an environmentally friendly polycarboxylate water reducing agent. Background Art

[0002] Polycarboxylate water reducer is a high-performance water reducer and a cement dispersant used in cement concrete. Generally, powdered polycarboxylate water reducer usually needs to be transported using conveying equipment. Due to the transportation requirements of the conveyor belt, its surface is designed to be uneven. Therefore, when transporting the water reducer, a large amount of water reducer will remain on the surface of the conveyor belt, thereby corroding the surface of the conveyor belt.

[0003] In order to prevent corrosion, brush-type equipment is usually designed on the surface of the conveyor belt to clean the conveyor belt. However, due to the small particle size of the powdered water reducer, it will be adsorbed on the surface of the conveyor belt due to the influence of static electricity on the surface of the conveyor belt, and it is difficult to completely brush it off with a brush. At the same time, the water reducer particles left in the dead corners are difficult to remove by conventional methods.

[0004] Therefore, the present application provides an automated production device and process for an environmentally friendly polycarboxylate water-reducing agent to meet the demand. Summary of the invention

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:

[0014] In the above scheme, by setting up a de-impurity device, when the residual water reducer on the belt transmission device enters the electrostatic box, the negative grid plate and the positive grid plate are powered, so that the discharge needle performs tip discharge, thereby forming an electric field between the discharge needle and the positive grid plate, and ionizing the air between them. When the powdered water reducer and dust fall into the formed electric field, they will be negatively charged. Under the action of the electric field, the powdered water reducer and dust will move to the bottom of the electrostatic box. At the same time, by driving an external vacuum pump, a negative pressure is formed inside the exhaust box. Through the guiding effect of the air guide groove 1 and the air guide groove 2, a negative pressure chamber is formed in the cloth storage bag, thereby absorbing the powdered water reducer and dust at the bottom of the electrostatic box, so that they are collected and precipitated in the cloth storage bag, thereby removing most of the water reducer on the conveyor belt.

[0015] By setting up a purification device, when the conveyor belt with the remaining water-reducing agent that has not been swept away enters the bottom of the pressing plate, alcohol liquid is injected into the feed trough tube through the feed pipe, and the injected alcohol liquid flows into the dipping arc groove through the feed trough tube, and the driving motor 2 drives the bristles on the hair roller to mix with the alcohol in the dipping arc groove to clean the residue on the conveyor belt. After that, when the conveyor belt wetted by alcohol passes through the electric heating plate, the electric heating plate is powered on to heat the conveyor belt, thereby drying the conveyor belt, thereby completely removing the powdered water-reducing agent on the surface of the conveyor belt, and avoiding the influence of the water-reducing agent on the conveyor belt.

When the conveyor belt with the residues enters the bottom of the pressing plate 312, alcohol liquid is injected into the conveying trough pipe 320 through the feeding pipe 321, and the injected alcohol liquid flows into the dipping arc groove 313 through the conveying trough pipe 320. At the same time, the second motor 317 is driven to drive the hair roller 314 to rotate, so that the bristles on the hair roller 314 are mixed with the alcohol in the dipping arc groove 313, so that the hair roller 314 cleans the residues on the conveyor belt. At the same time, the excess alcohol in the dipping arc groove 313 will fall into the second discharge trough 315 through the scraper 330, and the scraper 330 can clean the residues on the hair roller 314; S6: After the conveyor belt is cleaned, the conveyor belt wetted by alcohol is powered on when passing through the electric heating plate 340 to heat the conveyor belt, thereby drying the conveyor belt.

As the belt transmission device (110) operates, the conveyor belt with the residual water reducing agent moves into the cleaning box (210), and the driving motor 1 (213) drives the gear set (212) to rotate, thereby driving the two sets of cleaning rollers (211) to work, thereby sweeping off the water reducing agent powder and other powder dust on the surface of the belt transmission device (110); S3: The swept water reducing agent powder and dust fall from the cleaning box (210) into the electrostatic box (221).

When the powdered water reducing agent and dust fall into the formed electric field, they are negatively charged. Under the action of the electric field, the powdered water reducing agent and dust move to the bottom of the electrostatic box (221); S4: by driving an external vacuum pump, a negative pressure is formed inside the vacuum box (232), and through the guiding effect of the first air guide groove (233) and the second air guide groove (241), a negative pressure chamber is formed in the cloth storage bag (243), thereby absorbing the powdered water reducing agent and dust at the bottom of the electrostatic box (221), so that they are collected and precipitated in the cloth storage bag (243); S5: After the powdered water reducing agent and dust on the belt transmission device (110) are processed, some residues will still remain on the belt. When the conveyor belt with the residues enters the bottom of the pressing plate (312), alcohol liquid is injected into the conveying channel pipe (320) through the feeding pipe (321), and the injected alcohol liquid flows into the dipping arc groove (313) through the conveying channel pipe (320).

At the same time, the excess alcohol in the dipping arc groove (313) will fall into the second discharge trough (315) through the scraper (330), and the scraper (330) can clean the residues on the hair roller (314); S6: After the conveyor belt is cleaned, the conveyor belt wetted by alcohol is powered on when passing through the electric heating plate (340) so as to heat the conveyor belt, thereby drying the conveyor belt.
