JPH038486A - Device for cleaning casket - Google Patents

Abstract

PURPOSE:To rapidly remove powder by opposing a sandblasting device to a conveyor and providing a sandblasting part in the device on the upstream side of the conveyor. CONSTITUTION:A casket 11 is conveyed by a conveyor 10, and sand is blasted onto the entire casket 11 from the sandblasting nozzle 14 of the sandblasting device 12. Consequently, the powder, etc., firmly attached to the casket 11 are released. High-pressure air is then blown against the entire casket 11 from the first sir blowing pipe 15 of the device 12, and the powder, sand, etc., depositing on the casket 11 are blown off. The materials are collected by a suction-type dust collector 18. The casket is fully automatically cleaned in this way while being conveyed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an apparatus for cleaning powder and the like adhering to, for example, boxes on which objects to be fired are loaded.

(Prior art) Generally, when a box loaded with objects to be fired is heat-treated in a firing furnace while being conveyed by a conveyor, etc., and the objects to be fired are removed from the box, a large amount of powder etc. adheres to the empty box. and
This powder etc. needs to be removed.

Therefore, conventionally, as shown in Fig. 5, a dust collection hood 2 is provided to cover the top of the box I, and the dust collection hood 2 is connected to a suction type dust collector 3 to remove powder etc. by suction power. ing.

(Problem to be Solved by the Invention) However, with such a suction type dust collection method, although it is possible to remove powder, etc. that lightly adheres to the top surface of the box, it takes time to remove powder, etc. that has adhered to the top surface of the box. In particular, powder accumulated in the four corners of the box becomes a blind spot for the suction power, so
There was a problem that it could not be completely removed.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a new box cleaning device that can quickly and reliably remove powder and the like.

(Means for Solving the Problems) Therefore, the present invention provides an apparatus for cleaning powder etc. adhering to boxes, in which a sandblasting device is disposed with respect to a conveyor that conveys the boxes, and the sandblasting device is provided upstream of the conveyor inside the sandblasting device. A sandblasting section for removing powder etc. adhering to the box is provided on the side, and a first air blowing section for blowing high-pressure air over the entire box is provided downstream of the conveyor inside the sandblasting device. A suction dust collection hood that covers the top of the box is provided on the downstream side of the conveyor, and a second air blower that blows high-pressure air to the four corners of the box within the suction dust collection hood. be.

(Function) The sandblasting section of the sandblasting device sandblasts the boxes being conveyed by the conveyor to remove firmly adhered powder, etc., and the first air blowing section blows high-pressure air over the entire box to blow off the powder, etc. Sandblasting and powder are collected using the sandblasting device's suction type dust collector.

Furthermore, outside the sandblasting device, a second air blower inside the dust collection hood blows high-pressure air to the four corners of the box to blow away powder, etc., and the powder is collected by a suction-type dust collector connected to the dust collection hood. do.

(Effects of the Invention) According to the present invention, the sandblasting part peels off the powder etc. stuck to the box, then the first air blowing part blows off the powder etc. adhering to the whole box, and the second air blowing part blows off the powder etc. stuck to the box. By blowing away the powder etc. adhering to the four corners, powder etc. can be reliably removed in a short time, and furthermore, it is now possible to fully automatically clean the product while it is being conveyed by the conveyor.

In addition, since the first air blower in the sandblasting device blows off most of the powder, etc. and plasto sand,
The amount of blast sand taken out of the sandblasting device is minimized, and the need for replenishment of blast sand is reduced.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the cleaning device for the boxes 11 is provided with a conveyor IO, and the conveyor IO allows the boxes 11 to be cleaned. ...
, 11 are continuously conveyed at regular intervals.

A sandblasting device 12 is arranged on the upstream side of the conveyor IO, and an air blow/suction dust collector I3 is arranged on the downstream side of the conveyor.

Inside the sandblasting device 12, as shown in detail in FIG. 2, a sandblasting nozzle 14 is provided on the upstream side of the conveyor to remove powder etc. adhering to the boxes 11, and a sandblasting nozzle 14 is provided on the downstream side of the conveyor to apply high pressure to the entire box 11. A first air blow section 15 that blows air is provided.

Blast sand is blown onto the box 2 from the sandblasting nozzle 14.

The first air blow section 15 is provided with a vibrator 16 in the direction perpendicular to the conveyor, and a large number of blow holes 16a, . . . , L6a are formed in the pipe 16 in the direction perpendicular to the conveyor.
High pressure air is blown onto the entire box 11 from each blow hole 16a.

The suction dust collection hood I7 of the sandblasting device 12 is connected to a suction type dust collector 18.

The air blow/suction dust collector 13 is shown in Figs. 3 and 4.
As shown in detail in the figure, a suction dust collection hood 20 that covers the upper part of the box 11 is provided, and inside the suction dust collection hood 20, the box 11 is
A second air blow section 2 blows high pressure air to the four corners of the
1 is provided.

The second air blow section 21 has air blow nozzles 22a, . . . , 22d attached to the four corners of the suction dust collection hood 20.
High pressure air is blown to each of the four corners of i.

Suction dust collection hood 2 of the above air blow/suction dust collector 13
0 is connected to a suction type dust collector 23.

With the above configuration, when the box II is transported by the conveyor IO, plastic sand is first sprayed onto the entire box 11 from the sandblasting nozzle 14 of the sandblasting device I2, and as a result, the box II! Powder, etc. firmly attached to the surface will be peeled off.

Subsequently, high-pressure air is blown onto the entire box 2 from the first air blowing section 15 of the sandblasting device 12, thereby blowing off the powder, etc. and the blast sand adhering to the box 11.

The powder etc. and plasto sand blown away here are
The dust is collected by the suction type dust collector I8 without going outside from the suction dust collection hood 17.

In this way, the first air blower part 15 is used as the first air blower! Since most of the plasto sand adhering to the sand is blown away, the amount of plasto sand being taken out of the sandblasting device 12 is reduced.
There is less need to replenish plasto sand.

When the box 11 conveyed by the conveyor IO comes out of the sandblasting device I2, next, the air blow/suction dust collector 13
The suction dust collection hood 20 comes down, and high pressure air is blown from the second air blow section 21 to the four corners of the box 11.
As a result, powder etc. adhering to the four corners of the box 2 are blown away.

The powder, etc. blown away here is removed by the suction dust collection hood 2.
The dust is collected by the suction dust collector 23 without going outside.

In this way, the sandblasting nozzle 14 removes powder and the like from the box 11 conveyed by the conveyor 10, and the powder and the like are blown away by the first air blow part 15 and the second air blow part 2I. Powder, etc. can be removed reliably, and cleaning can be fully automated.
