Detailed Description

Referring to fig. 1-7, the dust removing device for casting surface shot blasting equipment of the utility model comprises a bin body 1, a dust pumping pipeline 2 connected with external casting shot blasting equipment is communicated on the outer wall of the bin body 1, and a pulse dust removing assembly 3 is arranged in the bin body 1 above the dust pumping pipeline 2; a drawer component 4 is arranged in the bin body 1 below the feeding hole of the dust extraction pipeline 2, and a vibrating screen assembly 5 is obliquely arranged in the drawer component 4. The pulse dust removing assembly is the prior art, and the specific structure thereof is common knowledge of those skilled in the art, and will not be described herein again. The shot that the dust extraction pipeline feed inlet came in because weight is heavier, can directly fall on vibrating screen assembly and export, and the dust is adsorbed in the top, falls in unison again after the dust extraction end, and vibrating screen assembly vibrates and makes the dust pass through, avoids the dust to pile up on the screen cloth.

A steel shot leading-out port 6 matched with the discharging end of the vibrating screen assembly 5 is arranged on the side wall of the bin body 1 below the feeding port of the dust pumping pipeline 2, and a V-shaped centralized guide chute 7 is arranged on the outer wall of the bin body 1 at the position of the steel shot leading-out port 6; a material collecting box 8 is detachably arranged at the discharge end of the concentrated material guide groove 7. The steel shot outlet and the dust exhaust pipeline are arranged on the same side of the feed inlet, so that dust entering from the feed inlet of the dust exhaust pipeline can be prevented from being directly blown into the steel shot outlet.

In the present embodiment, the vibrating screen assembly 5 includes an obliquely arranged screen 5a, and the mesh of the screen 5a is directly 0.1-1mm. The diameter specification of the steel shot used by the shot blasting machine is between 0.2 and 2.5mm, and the specification of the screen is selected according to the specification of the steel shot used in actual production.

One end of the screen 5a far away from the steel shot outlet 6 is positioned above and the bottom is provided with a first mounting seat 5b, the inner wall of the bin body 1 is provided with a second mounting seat 5c corresponding to the first mounting seat 5b, and a spring 5d is vertically connected between the first mounting seat 5b and the second mounting seat 5 c. After the dust removal is finished, the dust concentrated above the bin body impacts the spring when falling on the screen, so that the screen vibrates.

The bottom of one end of the screen 5a close to the steel shot outlet 6 is provided with a hinged seat 5e, and the discharge end of the screen 5a is hinged on the bin body 1 through the hinged seat 5 e. The discharge end of the screen is hinged on the bin body, so that the discharge position can be fixed, the height of the steel shot guide outlet is reduced, and less dust is output to the concentrated guide chute from the steel shot guide outlet.

In the present embodiment, the drawer assembly 4 comprises a through hole 4a disposed at one end of the bin body 1 along the width direction of the screen 5 a; a plurality of supporting cross beams 4b are connected between the bin bodies 1 at the lower ends of the through holes 4a; a drawer frame is arranged in the bin body 1 and consists of two side plates 4c which are matched with the through holes 4a and mounting cross beams 4d which are connected between the two side plates 4c and correspond to the supporting cross beams 4b one by one; the vibrating screen assembly 5 is fixedly arranged on the side plate 4 c; the upper end face of the mounting cross beam 4d is a cambered surface. During installation, the installation frame with the assembled screen mesh is pushed into the bin body from the through hole to be matched with the bin body, so that the quick assembly and disassembly of the vibrating screen mesh component can be completed, and meanwhile, the upper end face of the installation cross beam is set to be an arc surface to avoid dust accumulation on the installation cross beam.

And a sealing structure is arranged between the side plate and the through hole, sealing can be performed by adopting a sealing rubber strip, and the specific structure is common knowledge of the technicians in the field and is not described again.

A first handle 4e is arranged on the side plate 4c positioned at one side of the through hole 4a; a limit groove 4f corresponding to the side plate 4c is arranged on the outer wall of the bin body 1 at one end opposite to the through hole 4 a. After the installation frame pushed the storehouse body from the through-hole, it is said when the lateral wall that does not set up the first in command contacted with spacing inslot wall that the installation is in place promptly, makes things convenient for the counterpoint installation of installation frame to need not carry out extra sealing to the storehouse body lateral wall with the relative one end of through-hole.

In this embodiment, the discharge port of the concentrated material guiding groove 7 is arranged vertically downward, clamping grooves 9 are arranged on two sides of the discharge port of the concentrated material guiding groove 7, and a suspension clamping block 10 corresponding to the clamping grooves 9 is arranged on the material collecting box 8; the outer wall of the material collecting box 8 is provided with a limit baffle 11, and the limit baffle 11 is provided with a second handle 12. The material collecting box is quickly disassembled and assembled by matching the hanging clamping block with the clamping groove.

During operation, the pulse dust removal assembly cooperates with the dust extraction pipeline to extract dust in the shot blasting equipment into the bin body, and steel shots mixed in the dust directly fall on the screen and are guided out due to heavier weight. After the shot blasting is finished, the pulse dust removal assembly stops working, dust falls on the screen to enable the screen to vibrate to filter the dust, the small-size dust is output through the falling of the screen to be collected, and large-size impurities mixed in the dust are left on the screen and conveyed into the collection box along with the swinging of the screen.

The above embodiment is the preferred embodiment of the present invention, which is only used to facilitate the explanation of the present invention, it is not right to the present invention, which makes the restriction on any form, and any person who knows commonly in the technical field can use the present invention to make the equivalent embodiment of local change or modification without departing from the technical features of the present invention.
