Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

Example (b): the self-cleaning water reducing agent reaction kettle of the embodiment comprises a tank body 1, a jacket 2 is sleeved outside the tank body 1, a temperature adjusting cavity 3 is formed between the tank body 1 and the jacket 2, a liquid inlet pipe 4 for feeding cooling liquid is arranged on the side wall of the top of the jacket 2, a liquid discharge pipe 5 for discharging cooling liquid is arranged at the bottom of the jacket 2, a top cover 7 is arranged on the top of the tank body 1, a feeding pipe 9 is arranged on the top of the feeding pipe 9, a sealing cover 23 is arranged on the top of the feeding pipe 9, a plurality of groups of supporting seats 8 are arranged on the side wall of the tank body 1, a discharging pipe 6 is arranged at the bottom of the tank body 1, a stirring shaft 12 is rotatably connected in the middle of the top cover 7, a plurality of groups of stirring blades 13 are arranged at the bottom of the stirring shaft 12, a speed reducer 10 is connected at the top of the stirring shaft 12 through a, the bottom of lead screw step motor 14 is connected with lead screw 15, the bottom of lead screw 15 is rotated and is connected in the bottom of jar body 1, screw drive has ring shape scraper blade 16 on the lead screw 15, scraper blade 16 is equipped with the screw hole, lead screw 15 passes the screw hole, scraper blade 16 still is equipped with a plurality of through-holes, through-hole sliding connection has slide bar 21, slide bar 21 upper end is fixed in the top cap 7 bottom, slide bar 21 bottom is fixed in jar body 1 bottom, the bottom of top cap 7 is fixed with travel switch 22, scraper blade 16 moves upward and contacts diversion downstream behind travel switch 22, jar body 1 bottom also is fixed with travel switch 22, scraper blade 16 moves downward and contacts diversion upstream behind travel switch 22, the bottom of top cap 7 is fixed with ring water pipe 18, the bottom intercommunication of ring water pipe 18 has multiunit nozzle 20, ring water pipe 18 is connected with inlet tube 19, inlet tube 19 passes top.

Wherein, the side wall of the scraper 16 is fixed with a circle of rubber ring 17, and the rubber ring 17 slides on the inner wall of the tank body 1. Use flexible rubber circle 17 to strike off the water-reducing agent of adhesion on the reation kettle inner wall, reduced the rigidity friction, avoid scraping colored harm jar body 1 inner wall, reduce reation kettle life. While the rubber grommet 17 is more effective in scraping than a rigid material.

Wherein, stirring leaf 13 is anchor stirring leaf 13, and the length of stirring leaf 13 that is located the upper end is greater than the length of stirring leaf 13 that is located the lower extreme, and the vertical distance of stirring leaf 13 to (mixing) shaft 12 is less than the internal diameter of scraper blade 16. The pressure of the water reducing agent solution received by the lower end stirring blade 13 is greater than the pressure of the solution received by the upper end stirring blade 13, so that the length of the lower end stirring blade 13 is shorter than that of the upper end stirring blade 13, the motor 11 is favorably reduced, and the service life of the stirring blade 13 is favorably prolonged. Meanwhile, the vertical distance from the stirring blade 13 to the stirring shaft 12 is smaller than the inner diameter of the scraper 16, so that the scraper 16 does not contact with the stirring blade 13 during the up-and-down movement.

During the specific use, let in the coolant liquid to adjusting temperature chamber 3 from feed liquor pipe 4 earlier, later open the sealed lid 23 at inlet pipe 9 top, add the raw materials to the reation kettle, later open motor 11. The motor 11 rotates the electric stirring shaft 12, the stirring shaft 12 drives the stirring blade 13 to rotate, and the stirring blade 13 mixes and stirs the raw materials. The multiunit stirring leaf 13 is located the upper and lower position of reaction raw materials, can carry out intensive mixing to reaction raw materials, but because the length of every group stirring leaf 13 varies, so the vortex that every group stirring leaf 13 formed is also different to difficult formation stable vortex, just can not result in stirring inhomogeneous by the influence of vortex yet. And opening the discharge pipe 6 after the water reducing agent in the reaction kettle completely reacts, and discharging the water reducing agent from the discharge pipe 6. At this moment, the screw rod stepping motor 14 is started, the screw rod 15 starts to rotate, the rotating screw rod 15 drives the scraper 16 to move downwards, the rubber ring 17 outside the scraper 16 is in full contact with the inner wall of the reaction kettle, so that the water reducing agent adhered to the inner wall of the tank body 1 is scraped, and the water reducing agent falls into the bottom of the tank body 1 and is discharged from the discharge pipe 6. When the scraper 16 moves downwards to contact a travel switch 22 at the bottom of the tank 1, the scraper 16 moves and changes direction, and the scraper 16 starts moving upwards. When the squeegee 16 moves upward to contact the position switch 22 on the bottom of the top cover 7, the squeegee 16 moves again to change direction, and the squeegee 16 moves downward again. Thus, the scraper 16 reciprocates up and down to clean the inner wall of the can body 1.

In particular use, travel switch 22 may be controlled by a controller in order to increase the degree of automation of the reaction vessel. The optimum movement of the squeegee 16 is first from the top downward, which can reduce the retention of residual water reducing agent on the upper side of the squeegee 16.

When the scraper 16 is cleaned to a certain degree, the discharge pipe 6 is closed, and the external water source starts to feed water into the tank body 1 from the water inlet pipe 19. The water flows to the annular water pipe and down the scraper 16. Under the double actions of the reciprocating motion of the scraper 16 and the water flow, the inner wall of the tank body 1 is cleaned, the discharge pipe 6 is opened again, and the cleaning liquid is discharged into the tail liquid treatment tank.

The present embodiment is only an exemplary embodiment of the present invention, and for those skilled in the art, based on the application method and principle disclosed in the present invention, various modifications or variations can be easily made, and not only limited to the structure described in the above embodiments of the present invention, therefore, the manner described in the foregoing is only a preferred embodiment, but not limiting, and all equivalent changes and modifications made according to the present invention are within the scope of the present invention.
