Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dust removing device used for cleaning a carrying bag for a coagulant mixed in a cement raw material when the carrying bag is recycled.

[0002]

[Prior art]

 Cement is a cement clinker obtained by mixing raw materials containing lime, silica, alumina, and iron oxide in appropriate proportions, pulverizing them uniformly, and then firing this in a kiln to solidify gypsum etc. to control the setting. It is manufactured by adding an agent and pulverizing it into a fine powder.

Conventionally, when transporting this coagulant in a distribution process, a powdered coagulant was filled in a hemp transporting bag. Carrying bags have become expensive, so instead of conventional hemp bags, carrying bags made of synthetic resin such as polypropylene, which is a relatively cheap chemical synthetic product, are used.

This synthetic resin carrying bag has been used as a disposable bag until now, but nowadays, a new problem arises that it is difficult to treat it as industrial waste, and its solution and effective use of resources are required. From the point of view, it has been attempted to recycle. In order to recycle a synthetic resin carrying bag, it is sufficient to first clean the used bag, then repair the torn part and perform any other necessary reprocessing. When the bag is washed with water, the hydraulic coagulant that remains on the inside of the carrying bag solidifies and sticks to the bag, making it useless, and the carrying bag cannot be washed with water. The removal of the powdered coagulant has been a major obstacle for reusing the transport bag.

[0005]

[Problems to be solved by the device]

 The present invention is an attempt to improve the present invention in view of the above-mentioned circumstances, and the problem of the present invention is to remove the powdery coagulant remaining inside the carrier bag without washing it with water. The point is to make it possible, and its concrete means and action are as follows.

[0006]

[Means for Solving the Problems]

 A dust remover with a flat vertical box shape is provided by interposing it in the conveyer path of the conveyor that detachably suspends the carrying bag, and the above conveyer is inserted in the upper part of the dust remover. A suction hole is opened in the upper wall of the blower and a delivery hole is opened in the bottom wall of the blower. The feed-out hole is communicated with the suction side of the blower through the first dust collector, and at the same time, the blower is blown. The discharge side of is communicated with the second dust collector.

[0007]

[Action]

 When the carrying bag hung on the conveyor is transported inside the dust remover, the suction action of the blower causes an air flow in the dust remover from the suction hole to the delivery hole, and the air flow vibrates the carrying bag. As a result, the powdery coagulant that adheres and remains can be wiped off and the powdery coagulant removed. Further, the removed powdery coagulant can be sent to the dust collector by the air flow to be recovered.

By engraving the upper opening 8a of the carrying bag 8 onto the metal fitting body 9 and holding the opening 8a between the recess 13 and the projection 12 of the clip 11 via spring pressure, It is provided so that the carrying bag 8 can be suspended on the conveyor 2 with the opening 8a opened. A pair of front and rear clips 14 and 14 are attached to the conveyor 2 with a hanger fitting 7 interposed therebetween, and the clips 14 and 14 are provided so as to suspend both shoulders of the carrying bag 8.

A dust remover 3 is arranged at an arbitrary position on the conveying path of the conveyor 2, and a carrying bag 8 hung from a hanger fitting 7 of the conveyor 2 can pass through the dust remover 3 so as to pass therethrough. It is provided. That is, the dust remover 3 is formed in the shape of a flat vertical box, and the vertically long insertion openings 15 and 15 are opened at both front and rear ends thereof, and the conveyor 2 is provided at an upper position between the insertion openings 15 and 15. Is inserted.

A plurality of baffle bars 16 ... Staggered in a staggered manner are horizontally installed on the left and right inner wall portions of the dust remover 3 along the front-rear direction. In addition, a plurality of suction holes 17 ... Are opened in the top wall of the dust remover 3 so as to extend in the front-rear direction, while the bottom wall of the dust remover 3 corresponds to the lower position of each suction hole 17. Then, the delivery holes 18 ... Are opened. Each of the delivery holes 18 communicates with one end of an air delivery pipe 19, and the other end of the air delivery pipe 19 communicates with the intake side of the first dust collector 4.

A coarse filter 20 is provided inside the first dust collector 4 so as to be interposed between the intake side and the exhaust side, and is provided so that the filter 20 can perform primary dust removal. An air supply pipe 21 extends from the exhaust side of the first dust collector 4, and its tip end communicates with the suction side of the blower 5. The blower 5 is provided so that a fan installed therein can be rotated by driving a motor to generate a suction force.
