The invention discloses an anti-blocking dredging device for a discharge port of a ball mill. The anti-blocking dredging device comprises a hopper, a discharge pipe, the ball mill, a belt conveyor anda drilling machine; the hopper is provided with a sieve plate and a material blocking apron; the sieve plate is formed through combination of an upper sieve plate and a lower sieve plate; the upper sieve plate is connected to the right side of the rear end of the hopper through a rotating shaft; the lower sieve plate is connected on the left side of the rear end of the hopper through the rotatingshaft; each of the upper sieve plate and the lower sieve plate is provided with a round opening and a through hole; the material blocking apron is welded on the outer side of the hopper; the discharge pipe is in pipe connection at the bottom part of the hopper through an upper pipe section; an alkaline liquor pipe is in pipe connection between the discharge pipe and the upper pipe section; a material return pipe is welded at the rear end of the discharge pipe and is in pipe connection with the material blocking apron; the ball mill is installed at the rear end of the discharge pipe; the rearend of the discharge pipe is inserted into a feed port of the ball mill; the belt conveyor is installed above the hopper; and the drilling machine is installed right above the hopper. The anti-blocking dredging device can effectively prevent the phenomenon of blockage of the discharge pipe.

The invention relates to a welding repair method of expensive metal element. Wherein, it comprises (1), using general method to clean the surface of element; (2) increasing the temperature of element in furnace to 300Deg. C, keeping for 2-3h; (3), the basic layer of element is welded via direct current and using common steel welding solder; (4), when at 2-3mm from the shaping surface of repaired groove, using alternative current welding, to weld surface with color metal welding solder. The invention has low cost and wide application.

The positioning device, positioning structure and construction method of the steel bar fixture of the steel cage roll welding machine relate to the field of pile foundation steel bar processing. The chute between the card slots. The chute includes an outer sleeve with a rectangular arc shape in cross section and an inner block with a rectangular arc shape in cross section that is adapted to be movably inserted into the outer sleeve. Adjacent; the middle part of the outer surface of the inner inserting block is fixedly connected with a C-shaped clamping block along the long axis. Go through the bolt holes and tighten on the C-shaped clamping block. The invention solves the problems in the prior art that when a steel cage roll welder processes steel cages with different diameters and different numbers of main bars, it needs to be stopped to replace the clamps in place, and workers hold a ruler to adjust the distance between the clamps. The process is time-consuming and has low precision.
