Abstract

The utility model relates to a dust remover used for the cleaning ingot mold, which is composed of a dust pipe, a subpressure dust suction port positioned at the lower end of the dust pipe. A discharge pipe which is open at one end and an air inlet pipe which is communicated with a compressing air supply at one end are arranged at the upper end of the dust pipe, the discharge pipe and the air inlet pipe are respectively arranged at two sides of the dust pipe, the included angle between the discharge pipe and the dust pipe presents an obtuse angle, the included angle between the air inlet pipe and the dust pipe presents an acute angle, the included angle between the air inlet pipe and the discharge pipe presents an obtuse angle or an acute angle, and the dust pipe, the air inlet pipe and the discharge pipe are communicated with each other at the joint point. When cleaning the ingot mold, operators need not to enter into the ingot mould, only directly stand on the ingot mold to connect a corresponding air connection tube with the air inlet pipe, after opening a valve, the compressing air is discharged from the air inlet pipe to the discharge pipe, the subpressure dust suction is formed at the port of the dust pipe, the operators hold the dust remover with hands, lead the subpressure dust suction port to aim at the ingot mold and the part to be cleaned in the channel, so as to finish cleaning work of each ingot mold one by one.

Description

Cleaning ingot mould dust arrester

Technical field

The utility model relates to a kind of steel ingot casting frock, particularly a kind ofly is used to clear up in the ingot mould and the dust arrester of foreign material such as Tang Daonei dust, sand grains.

Background technology

In the steel ingot casting process, the mould preparation operation is the indispensable operation before the steel ingot casting, in the mould preparation operation, clears up in the ingot mould and foreign material such as the dust of Tang Daonei, sand grains by the brush die process.At present, brush mould operation generally adopts the tumble mode of cleaning of ingot mould off-line to clear up, but because the die wall dry slag in the ingot mould is not easy to remove clean under hot state, and complete the teeming stage from the brush mould, along with the ingot mould decrease of temperature, die wall dry slag residual on the ingot mould also can come off to some extent; In addition, in this stage, dust in the factory building also can accumulate in ingot mould in sedimentation constantly, and die wall dry slag that these come off subsequently and the dust that accumulates if do not clean out, can produce significant effects to the internal soundness and the surface quality of steel ingot finished product before the steel ingot casting.

The utility model content

The purpose of this utility model provides a kind of dust arrester that can clear up ingot mould and Tang Daonei dust and foreign material before teeming easily.

For achieving the above object, the utility model adopts following technical scheme: cleaning ingot mould dust arrester, comprise sweep-up pipe, the lower end of sweep-up pipe is the negative pressure suction port, the upper end of sweep-up pipe is provided with delivery pipe that an end opens wide and an end and is used for the air inlet pipe that is communicated with compressed gas source, the be placed in both sides of sweep-up pipe of air inlet pipe and delivery pipe, and the angle of delivery pipe and sweep-up pipe is in obtuse angle, the angle of air inlet pipe and sweep-up pipe is acute angle, and the angle of air inlet pipe and delivery pipe in obtuse angle or the straight angle; Sweep-up pipe, air inlet pipe and delivery pipe interconnect in intersection.

Sweep-up pipe and delivery pipe are formed to the pipeline of a lateral buckling by an epimere part, and the bending pipeline section is a delivery pipe, and air inlet pipe is located on the reverse extending line of bending pipeline section.

The angle of delivery pipe and sweep-up pipe is 100 °-120 °.

When using this device cleaning ingot mould, operating personnel need not enter in the ingot mould, stand directly on to utilize on the ingot mould and be fixed on compressed air piping (pressure is not less than 3kg) and the corresponding controlled valve that waters on the steel platform pillar, air connection flexible pipe by correspondence is connected with the air inlet pipe of this dust arrester, after opening valve, compressed air enters from delivery pipe from air inlet pipe and discharges, compressed air stream has just formed powerful suction force in sweep-up pipe, suction port place at sweep-up pipe forms the negative pressure dust suction, operating personnel hand dust arrester, make its negative pressure suction port aligning ingot mould and Tang Daonei position for clearance can finish the cleaning one by one of each ingot mould.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Cleaning ingot mould dust arrester shown in Figure 1, comprise the sweep-up pipe 1 and the delivery pipe 2 that form to the pipeline of a lateral buckling by epimere part, the bending pipeline section is a delivery pipe 2, on the reverse extending line of bending pipeline section 2, be provided with an end and be used for the air inlet pipe 3 that is communicated with compressed gas source, three pipes interconnect in intersection, the lower end of sweep-up pipe 1 is a negative pressure suction port 4, and delivery pipe 2 is 115 ° with the angle of sweep-up pipe 1.
