1. The device comprises a tank body, 2 end covers, 3 liquid inlet pipes, 4 liquid outlet pipes, 5 processing boxes, 6 sealing covers, 7 filter screens, 8 receiving boxes, 9 flow guide pipes, 10 metering pumps, 11 drainage pipes, 12 longitudinal shafts, 13 knocking handles, 14 knocking blocks, 15 swing motors, 16 bosses, 17 bolts, 18 sealing rings, 19 clamping grooves, 20 clamping strips, 21 liquid outlet valves and 22 supporting legs.

Detailed Description

The following description of the present invention will be made in detail with reference to the accompanying drawings 1 to 6.

In the first embodiment, the technical scheme for solving the problem is that impurities in the cement grinding aid are generally precipitated particle impurities, and the cement grinding aid flowing out of the liquid discharge pipe 4 flows to the filter screen 7 in a parabolic manner under the action of inertia, so that the arranged filter screen 7 can filter the impurities, and the impurities blocked by the filter screen 7 are flushed into the bearing box to be precipitated by matching with the beating vibration of the filter screen 7 and the flushing of the cement grinding aid by the beating device. Under the effect of inertia, the cement grinding aid flowing out of the discharge pipe 4 will flow in a parabolic manner towards the sieve 7.

When the novel cement grinding aid is used, the cement grinding aid can be introduced into the tank body 1 through the liquid inlet pipe 3 for storage, and when the end cover 2 is opened, the opening at the upper end of the tank body 1 can be used as a manhole so as to enter the tank body 1 for maintenance; the filter screen 7 is detachably connected in the treatment box 5 through the matching of the clamping groove 19 and the clamping strip 20, so that the filter screen 7 is convenient to overhaul and replace; the filter screens 7 are obliquely arranged in a mode that the left side is low and the right side is high and correspond to the inlet end of the treatment box 5, so that the cement grinding aid entering the treatment box 5 through the liquid discharge pipe 4 can be conveniently filtered, and the oblique arrangement of the filter screens 7 is beneficial for impurities falling on the filter screens 7 to enter the receiving box 8 under the scouring of the cement grinding aid, so that the filter screens 7 are prevented from being blocked by the impurities; the rapping device that is equipped with can beat vibrations to filter screen 7, avoids impurity to adhere to on filter screen 7, and the washing away of cooperation cement grinding aid, impurity can't be attached to on filter screen 7 and by being washed into and accept box 8, only needs to carry out periodic cleaning to accepting the impurity in the box 8.

When the rapping device works, the swing motor 15 drives the longitudinal shaft 12 to swing back and forth, and the rapping blocks 14 at two ends of the rapping handle 13 can alternately rap the filter screen 7 along with the reciprocating swing of the longitudinal shaft 12, so that the filter screen 7 vibrates, and impurities are prevented from being attached to the filter screen 7. The clamping groove 19 is matched with the clamping strip 20 to slidably mount the filter screen 7 into the treatment box 5.
