Abstract

The present invention in the waste ready mixed concrete aggregate sorting machine for separating waste ready mixed concrete in the factory of ready-mixed concrete manufacturing facilities to more efficiently install the structure of the rotating drum for sorting aggregates by size of each type to make the screening of aggregate very efficiently Of course, it is easy to sort the aggregate by suppressing the occurrence of load or the occurrence of failure to a minimum.

In constructing a rotating drum installed in the selection of aggregate is to install a certain facility in the inlet and outlet of the aggregate installed on the front side of the rotation to facilitate the separation of the aggregate.

Description

Waste Ready Mixed Concrete Aggregate Sorter {Waste Ready Mixed Concrete aggregate sorter}

The present invention relates to an aggregate screening device for waste ready mixed concrete produced by ready mixed concrete manufacturing company.

The present invention is for the purpose of sorting the gravel, sand, recovery water, but mainly used to separate and sort the gravel, sand, recovery water of the waste ready-mixed concrete produced by the ready-mixed concrete manufacturing company, in particular, sand and gravel, recovery water The main focus is to provide a structural device of the waste ready mixed concrete aggregate sorter.

After the work is delivered to the user, the remaining amount of ready-mixed concrete ready for use and the used ready-mixed concrete produced after washing the drum of the mixer vehicle are collected and reused. It is essentially followed by a separation process. In general, the separation process is performed by separating a vibrating body vibrated by an oscillator (in the case of sand, mainly using a reverse inclined guide plate) and a method of passing through a screen sieve to supply waste concrete to the guide plate. As a result of repeated movement, the aggregate is moved and collected.

Until now, gravel and sand have been collected separately by separate equipment in the reprocessing of such waste ready-mixed concrete.

That is, conventionally, by collecting the vibrating body and sand, the separation of the gravel by the rotation of the screen sieve and the sand collection of water (recovery) containing sand, the sand is introduced from the first stage sorting device, and the sand is used again by using an underwater pump The two-stage sorting operation is carried out by dehydrating and recovering by vibrating body or screw (splitting device of sand, rotating device with central wing).

However, the conventional sorting work of the ready-mixed ready-mixed concrete can solve problems such as excessive installation cost that must be provided separately, such as vibrating body, sand sorting device, submersible pump, or waste of work time and labor for dehydrating sorted sand. Expose

The present invention in consideration of the above problems by vibrating method, the method of flowing through the screen sieve flows down to the sand collector, the vibrating body which is a problem of the method of flowing down the recovered water to the bottom, the sand collector of the lower screen, the secondary sorting device Remove the screw, separate the gravel, sand, water (recovery) using the cylindrical self-rotating drum, do not use the submersible pump, and use the general pump and pneumatic pump to separate the water (recovery) By providing gravel and sand, water (recovery) to provide a waste ready mixed concrete aggregate selector, characterized in that to perform the work at the same time.

This figure is a front view of the cross section of the rotating drum according to the present invention cut away (a part of the bottom).

In the present invention, the rotating drum (1) and the end portion of the rotating drum is inclined (4) shape is installed in the center of the drum (2) screen sieve (the aggregate is not allowed to pass through the sand and water) And the spiral gravel conveyance guide plate 3 are attached, and the guide plate 3 and the screen body 2 are set lower than the water level 15 of the rotating drum 1 to contact the water (recovery) inside the drum. It is installed to wash the gravel and the washed gravel is a structure that can be discharged to the discharge hole of the gravel along the guide plate (3) of the spiral

Spiral wings (14) are attached to the bottom of the rotating drum, and the inclined part is a part of the clogged iron plate (4) from the bottom of the base, and the upper part is a double (11, 12) Sand transfer guide vanes 13 formed by spiral screen sieves and drum bottoms (9,12) are installed as screens (sand cannot pass through, but water and sludge only). It can be separated and discharged to the outlet (7) of sand

The water injected into the drum (recovery: including cement sludge) is installed so that the discharge port 16 of water (recovery water) is installed in the lower part of the inlet lower than the inlet 17 and discharged. The separation of the (recoverable water) is caused by the difference in specific gravity (specific gravity of sand: 2.5) so that the sand sinks to the bottom of the rotating drum, so that the spiral sand guide plate 14 moves forward to the inclined part at the rear and is separated.

The inclined part is doubled so that the inner screen guide plate (13) and the bottom part (9,12) are installed as screen sieves (sand cannot pass through, water (recovery) passes through) and the outer drum (10). This is a ready-mixed concrete ready-mixed concrete selector installed to clean the screen sieve (9, 12) by making the door open with bolts.

The first gravel separator, the second sand separator, and the third wet sand separator (aka wet cyclone. It is supposed to provide a waste ready-mixed concrete aggregate sorter which reduces the failure rate by separating gravel, sand, and recovered water from a single waste ready-mixed concrete aggregate sorter without using it.

The present invention, by first screening the gravel and sand to recover the gravel and then moving the sand back to the submersible pump to avoid the operation of dehydrating the sand to reduce the installation cost of the device by integrating this operation and in particular to reduce the work time And it reduces the waste of manpower and improves productivity.
