The invention discloses an anti-seepage grouting device and technology for a cast-in-place pile, and particularly relates to the technical field of grouting of the cast-in-place pile, the device comprises a grouting machine and a slurry storage barrel, one end of a connecting pipe is provided with a grouting mechanism used for grouting, differential management of branch pipelines is achieved through the grouting mechanism and an intelligent pressure controller during grouting, and the grouting efficiency is improved. The grouting material can be effectively utilized, so that more slurry is saved, the slurry is diffused more uniformly, the continuity of an impervious layer is better, the slurry is directionally jetted due to compression expansion of the elastic microporous sleeve, the construction time of a single pile can be shortened through a directional jetting technology, the comprehensive manufacturing cost is reduced, and the process is divided into three grouting stages, so that the construction efficiency is improved. A main body impervious layer is formed through first-time grouting, shrinkage cracks are filled for the second time, pressure is maintained for the third time to ensure compactness, the shrinkage cracks are better eliminated through the three-time grouting technology, and the permeability coefficient of a pile-soil interface is reduced.

The utility model discloses a composite cloth macromolecule sizing device with temperature adjusting and heating functions, which comprises a working box, a partition plate is fixedly connected in the working box, heating blocks are arranged in the partition plate and the working box, a second guide roller is rotatably connected in the working box, and a first guide roller is rotatably connected in the working box. And first guide rollers are rotationally connected to the positions, on the two sides of the second guide roller, in the working box correspondingly, and a first rotating shaft and a third rotating shaft are connected to the bottom end in the working box correspondingly. In the use process, the motor is started to drive the third rotating shaft to rotate, and the third rotating shaft drives the first rotating shaft to rotate under the action of the first belt pulley, so that the two groups of stirring cylinders can be synchronously driven to rotate, the multiple groups of stirring paddles are driven to mix slurry in the working box, and the slurry is kept flowing dynamically; therefore, the quality of subsequent finished products is improved.

The utility model provides a cleaning and recycling system for a lithium battery slurry conveying pipeline, relates to the technical field of lithium battery production equipment, and solves the problems that slurry cleaning is not timely enough through manual operation, the slurry is wasted and potential safety hazards exist in an existing lithium battery slurry conveying pipeline. The device comprises a conveying main pipe for conveying slurry and a pipe cleaning ball for cleaning the conveying main pipe, wherein the conveying main pipe is sequentially connected with a ball inlet, a coating buffer tank, a first transfer tank, a second transfer tank and an inlet end of a ball taking cage from the head end to the tail end; the outlet ends of the ball taking cage, the first transfer tank and the second transfer tank are respectively connected with the inlet end of a filter and a blow-down valve, the outlet end of the filter is connected with the inlet end of an iron remover, the outlet end of the iron remover is connected with a conveying main pipe, and a screw pump is connected between the blow-down valve and the filter. The device has the beneficial effects that pressure and residual slurry at the tail end are released to the transfer tank, so that the personnel safety is ensured, and the cost is reduced.
