Abstract

The utility model relates to a sand core batch seam cleaning device, which comprises a box body without a bottom, and the innovative points are that the side wall of the box body is fixed with a hollow sand blasting plate, wherein one surface of the sand blasting plate faxing to a box body inner cavity is full of sand blasting ports, the tail end of the sand blasting plate is communicated with a gas distribution pipe, and the gas distribution pipe is provided with a high pressure gas inlet and a suck sand mouth. The bottom portion of the box body is connected with a sand collecting hopper, the bottom portion of the sand collecting hopper is communicated with the suck sand mouth through a pipeline, and a filter screen is arranged between the bottom portion of the box body and the sand collecting hopper. The high pressure gas inlet of the gas distribution pipe is pumped with high pressure gas in use, sands in the sand collecting hopper enters the suck sand mouth through the pipeline under the action of pressure difference, and are blown into the sand blasting plate with the high pressure gas, is ejected from sand ejection mouths in high speed, and beats on batch seams of sand cores to knock out the batch seams, and the sands fall on the sand collecting hopper on the lower portion of the filter screen to be consciously reused. The sand core batch seam cleaning device does not to be treated artificially, thereby reducing the labor strength of workers, and increasing the cleaning efficiency.

Description

A kind of core is criticized the seam cleaning plant

Technical field

The utility model relates to a kind of core and criticizes the seam cleaning plant, particularly a kind ofly is used for the device that the Rapid Cleaning core is criticized seam.

Background technology

When carrying out the making of foundry sand type, usually on sand mold forming mould core, produce batch seam, for guaranteeing the quality of sand mold, need clear up batch seam, generally adopt file to carry out manual trim, labor strength is big, and efficient is low.

The utility model content

The technical problems to be solved in the utility model provides a kind of device that the Rapid Cleaning core is criticized seam that is used for, and need not manual trim, has reduced working strength of workers.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of core is criticized the seam cleaning plant, the casing that comprises the no end, its innovative point is: the sidewall of described casing is fixed with the sandblast plate of a hollow, this sandblast plate is covered with sand jet outlet towards the one side of cabinets cavity, the end of this sandblast plate is communicated with a gas-distribution pipe, and described gas-distribution pipe has a pressurized gas inlet and a suction sand mouth; The bottom of described casing is connected with a collection sand hopper, the bottom of described collection sand hopper by pipeline with inhale the sand mouth and be communicated with, and in the bottom of casing and collect between the sand hopper and be provided with filter screen.

Advantage of the present utility model is: during use, the pressurized gas inlet of gas-distribution pipe feeds gases at high pressure, under the pressure differential effect, sand in the collection sand hopper enters by pipeline inhales the sand mouth, together be blown into the sandblast plate with gases at high pressure, spray at a high speed from sand jet outlet, beat batch sewing on of core batch seam is destroyed, sand continues to recycle by the collection sand hopper that filter screen falls into the below.Need not to handle manually, reduced working strength of workers, and improved cleaning efficiency.

Description of drawings

Fig. 1 criticizes seam cleaning plant front view for the utility model core.

Fig. 2 is along A-A line cutaway view among Fig. 1.

The specific embodiment

As shown in Figure 1, 2, comprise casing 1, sandblast plate 2, sand jet outlet 3, air jet pipe 4, collection sand hopper 5, filter screen 6.

Above-mentioned casing 1 is a bottomless box, low sidewall is fixed with the sandblast plate 2 of a hollow, this sandblast plate 2 is covered with sand jet outlet 3 towards the one side of casing 1 inner chamber, is communicated with a gas-distribution pipe 4 at the end of sandblast plate 2, and this gas-distribution pipe 4 has one and has a pressurized gas inlet a and one and inhale sand mouth b.

Be connected with a collection sand hopper 5 in the bottom of casing 1, the bottom of this collection sand hopper 5 is communicated with the suction sand mouth b of gas-distribution pipe 4 by pipeline, and filter screen 6 is located between collection sand hopper 5 and the casing 1.

During work, contain sand in the collection sand hopper 5, the pressurized gas inlet a of gas-distribution pipe 4 inserts gases at high pressure, under the pressure differential effect, sand in the collection sand hopper 5 enters by pipeline inhales sand mouth b, together be blown into sandblast plate 2 with gases at high pressure,, beat batch sewing on of core and destroy batch stitching from sand jet outlet 3 ejection at a high speed.

Claims

1. a core is criticized the seam cleaning plant, the casing that comprises the no end, it is characterized in that: the sidewall of described casing is fixed with the sandblast plate of a hollow, this sandblast plate is covered with sand jet outlet towards the one side of cabinets cavity, the end of this sandblast plate is communicated with a gas-distribution pipe, and described gas-distribution pipe has a pressurized gas inlet and a suction sand mouth; The bottom of described casing is connected with a collection sand hopper, the bottom of described collection sand hopper by pipeline with inhale the sand mouth and be communicated with, and in the bottom of casing and collect between the sand hopper and be provided with filter screen.
