Embodiment Construction
[0017] Such as figure 2 As shown, the automatic sand blowing device of the present invention includes: four non-driven rails 1, two sets of supporting wheels, retaining wheel bracket 15 and sand blowing device 9, two non-driven rails 1 are arranged in a straight line, and there is a transverse direction between them. Interval, the above-mentioned two non-drive rails 2 form a group, and the four non-drive rails 1 are divided into two groups, and each group is aligned and arranged in parallel, with a longitudinal interval between each group. In the space formed by the horizontal interval and the longitudinal interval of the track 1, two groups of supporting rollers are arranged in parallel front and back, and a stop wheel support 15 and a sand blowing device 9 are installed at the center of a distance from the front ends of four non-driven rails 1 . The supporting wheel set includes: supporting wheel base 10, supporting wheel frame 13, left supporting wheel 3 and right supporti...

The invention provides an automatic sand-blowing device comprising at least four non-driven tracks, at least two supporting wheel sets, a retainer wheel support and a sand blowing device body. Each supporting wheel set comprises a supporting wheel base, supporting wheel frames, a left supporting wheel and a right supporting wheel, the left supporting wheels and the right supporting wheels support a nodular cast iron pipe and are respectively installed on the supporting wheel frames, one of all the left supporting wheels or one of all the right supporting wheel is driven by a motor to rotate, one supporting wheel frame provided with one left supporting wheel and one supporting wheel provided with one right supporting wheel are symmetrically fixed on the left side and the right side of each supporting wheel base through regulating screws, and the regulating screws are used for regulating the positions of the supporting wheel frames provided with the left supporting wheels and the right supporting wheels relative to the centers of the supporting wheel bases. The retainer wheel support is provided with a retainer wheel which rotates freely, and the sand blowing device body is installed above the retainer wheel. According to the automatic sand-blowing device, rotary sand blowing is adopted, the characteristic that the nodular cast iron pipe has a conical degree is utilized, the angles of the supporting wheel sets are regulated, therefore, fixation of the position of a bellmouth is guaranteed, labor intensity of people is lowered, efficiency is improved, and blowing quality is improved greatly.
Description
technical field [0001] The invention relates to an automatic sand blowing device, in particular to an automatic sand blowing device for a nodular cast iron pipe annealing furnace socket. Background technique [0002] At present, before the annealing of ductile iron pipes at home and abroad, the residual core of the socket is often left in the socket, and after the annealing furnace, it is sprayed and cooled after the furnace, and the socket sand sticks to the inner wall of the socket, which directly affects the lower In the first process, the socket is polished, and all the residual sand cores must be cleaned before the annealing furnace is put into the furnace. At present, sand blowing in the same industry uses people to stand in front of the pipe socket, the pipe is fixed on the track, and the air pipe is used to blow it. The temperature of the pipe is often above 700 ° C. Working in this high temperature environment is harmful to people. It consumes a lot of physical str...
