Embodiment 1

[0028] like Figures 1 to 3 As shown, a pneumatic unclogging device for finished casting sand storage hoppers provided in this embodiment includes a sand storage hopper 1 with a conical structure. The upper sand inlet of the sand storage hopper 1 is larger than the lower sand outlet, and it also includes four Hollow pipes 2 and four hollow pipes 2 are equally spaced along the circumference of the sand storage bucket;

[0029] The four hollow tubes 2 pass through the outer wall of the sand storage bucket 1 respectively, and the included angles between the four hollow tubes 2 and the outer wall of the sand storage bucket 1 are the same, and the distance between the junctions of the four hollow tubes 2 and the outer wall of the sand storage bucket 1 is The height of the falling sand opening under the sand bucket 1 is the same, and the center delay lines of the four hollow tubes 2 all point to the falling sand opening of the sand storage bucket 1, because the center delay lines of...

Embodiment 2

[0032] This embodiment provides a method of using a pneumatic unclogging device for sand storage hoppers of cast finished products. In actual production, the lower sand drop opening of the sand storage hopper 1 is connected to the square sand discharge opening, so the blocking of the sand storage hopper 1 The place is the transitional surface between the lower sand falling port and the square sand discharging port. When the sand discharging system is blocked, open the air supply valve to fill the annular hollow pipe 3 with high-pressure gas, and the annular high-pressure gas passes through the 4 hollow pipes 2 to the lower falling port. High-pressure cleaning is performed at the transitional surface between the sand mouth and the square sand outlet; the air supply pressure of the air supply valve is 0.6-0.8Mpa, and the duration of high-pressure cleaning is 2-3 seconds.

Abstract

The invention discloses a pneumatic blockage cleaning device for a sand storage bucket of casting finished product sand. The device comprises the sand storage bucket of a round-table-shaped structure, a sand inlet in the upper portion of the sand storage bucket is larger than a sand falling opening in the lower portion, and four hollow pipes are further included and are distributed at equal intervals along the circumference of the sand storage bucket; the four hollow pipes penetrate the outer wall of the sand storage bucket, included angles between the four hollow pipes and the outer wall of the sand storage bucket are the same, the distances between the interfaces of the four hollow pipes and the outer wall of the sand storage bucket and the height of the sand falling opening in the lower portion of the sand storage bucket are the same, the center delay lines of the four hollow pipes point to the sand falling opening in the lower portion of the sand storage bucket, the ends, located outside the sand storage bucket, of the four hollow pipes are in seal communication connection with an annular hollow pipe, the sand storage bucket is sleeved with the annular hollow pipe, an air inlet is formed in the annular hollow pipe, and an air inlet control valve is connected to the air inlet; the invention further designs a using method of the pneumatic blockage cleaning device for the sand storage bucket of casting finished product sand.

Description

technical field [0001] The invention relates to the technical field of production and application in the foundry industry, in particular to a pneumatic plugging removal device for a sand storage hopper for casting finished products and a method for using the same. Background technique [0002] The finished product sand storage bucket is one of the necessary facilities for mechanized and semi-mechanized casting production lines. Most microseismic molding production lines use air valves to control the mechanical opening and closing under the sand storage bucket to ensure the normal operation of the molding line sand; [0003] However, because the water content of the finished sand is 3.5-5.5%, and the binder is 3-8%, this determines that the fluidity of the finished sand is relatively poor, so it is necessary to supply sand and open the sand storage bucket pneumatically during the normal production process. The mechanical separation and closing valve below has the phenomenon ...
