Abstract

The present invention relates to a construction aggregate sorting washing machine that can be washed together during the classification of the aggregate used in the construction work as aggregate, such as general gravel, small gravel, sand.

Conventionally, there is a separate device for screening aggregates only by size, and the screening and cleaning work are dualized and cumbersome because the aggregated screened by size in the screening device is put back into the aggregate washer and washed in a separate process. There was an inefficient disadvantage.

The present invention is to solve the above-mentioned disadvantages of the conventional aggregates to transport the aggregate by the spiral feed vanes formed on the inner circumferential surface of the washing drum to be rotated to flow the water in the opposite direction to the aggregate transport direction to wash the aggregates The small gravel sorting network inside the washing drum of the washer and the general gravel sorting network are installed and rotated concentrically, and the water jet pipe is inserted into the central space to spray the water. When sand is put in, the general gravel is picked up by the general gravel sorting network, and the small gravel passing through the general gravel sorting network is sorted by the small gravel sorting network, and the sand is sorted through the small gravel sorting network. It is water sprayed from the water injection pipe to clean general gravel and small gravel The dropped sand is a very useful construction aggregate sorting washer that is cleaned by the flowing water collected on the bottom of the washing drum to simultaneously sort and wash the aggregates.

Description

Aggregate Screening Washer for Construction

The present invention relates to a construction aggregate sorting washing machine that can be washed together during the classification of the aggregate used in the construction work as aggregate, such as general gravel, small gravel, sand.

The prior art has been proposed by the inventor of the present invention on May 22, 1995, utility model registration application (Application No.: 95-10949), and the construction sand cleaning disclosed as Utility Model Publication No. 96-36458. As the configuration of the device, the aggregates are only washed by sending water in the opposite direction to the conveying direction of the aggregate while transferring the aggregate by the spiral feed vanes formed on the inner circumferential surface of the rotating drum. Since there is no sorting function, the process of sorting by the size of the aggregates has to be carried out by a separate sorting device in the first step of the washing operation and has the disadvantage of being inefficient.

Therefore, the present invention was devised to solve the above-mentioned disadvantages of the prior art, and its purpose is to insert aggregates to select aggregates in the interior of the conventional aggregate washer and to select aggregates in one device. By constructing so that it can be washed at the same time, it is possible to obtain high quality aggregates by washing and removing the soil and dirt contained in the aggregates while sorting the sands of the streams by general gravel, small gravel, sand, etc. by size.

Hereinafter, described in detail by the accompanying drawings a preferred embodiment for achieving the object of the present invention as follows.

First, the inventor of the present invention, which is a prior art, describes the main configuration of Utility Model Registration Application No. 95-10949 (Building Sand Washing Device) filed on May 22, 1995, as in the accompanying drawings;

A hat-shaped discharge plate (5) having a spiral feed vane (2) attached to the inner circumferential surface of the washing drum (1), and having a plurality of sand discharge pieces (4) having a manhole on the front sand discharge port (3). ), And lower the jaw height of the water outlet 6 in the rear than the jaw height of the sand outlet 3 in the front, and the rail 7 rounded to both ends of the outer cylindrical surface of the washing drum 1 is lower. It is configured to be rotated by the chain 23 of the sprocket (9) rotated by the engine or the drive motor of the washing drum (1) which can be rotated supported by the roller (8) of the;

A feature of the present invention is that two sorting nets having a sorting function of aggregate are inserted into the washing drum (1) of the conventional washing apparatus so as to be rotated.

In other words, the aggregate put into the sorting wash constitutes a general gravel sorting network (10) having a diameter of about 25 mm and is inserted into the small gravel sorting network so that general gravel having a diameter of about 25 mm or more is caught and sorted. (11) has a diameter of about 6 mm and a diameter of about 6 mm or more so that small pebbles with a diameter of 25 mm or less can be hooked and sorted, so that the two sorting nets 10 and 11 are disposed inside the washing drum 1. It is inserted into the concentric circle and supported by the sorting network support roller 12 installed at the inner both ends of the washing drum (1) while being opposite to the washing drum (1) by the drive pulley (13) and the rotating shaft (14) in front of the washing machine. It is configured to rotate in the direction.

Here, the washing drum (1) so that the conveying speed of the general and small gravel by the two sorting network (10, 11) on the upper side than the conveying speed of the sand washed by the rotation of the washing drum (1) is faster It is preferable that the two sorting nets 10 and 11 rotate at about 10 revolutions per minute at 4 to 6 revolutions per minute.

In addition, the inner circumferential surfaces of the general gravel screening net 10 and the small gravel screening net 11 so that the transfer direction of the selected aggregate is transferred to the rear side of the washing machine, that is, the sand transfer direction of the bottom surface of the lower washing drum (1) Is to be attached to the inner circumferential surface of the sorting network so that the spiral feed vanes (2) are transported in the opposite direction.
