Description

Screen Non-blocking Device at Drum Type Separator

The present invention is a device for preventing the closing of the net by soil or foreign matter in the drum type sorter, and in detail, the net is removed by continuously shaking the soil or foreign matter blocking the net pain by hitting the net pain with a rubber batting stand. It relates to a network closure prevention device configured to prevent the closing of.

Drum type sorter is a device for sorting aggregates of effective size by the sieving action of a rotating cylindrical sorting network. It is used for sorting waste in construction field or separating waste and aggregate in waste field.

Such a drum type sorter is separated and separated into aggregates (including sand and soil) discharged to the lower portion of the net through a certain size of the net and aggregates or foreign substances of large size discharged to the rear without passing through the net.

This type of drum type sorter separates small sized sand or earth dust by the sieving action of the sorting network. Therefore, by using a small sized net, the sedimentation of the soil is attached to the net as the sorting proceeds. do.

If the screen is clogged, the screening efficiency decreases drastically, so after stopping the screening for a certain period of time, stop the operation and shake off the network or install a brush on the side of the screening network. It is known to prevent the closing of the net by intermittently hitting the sorting net using a rod.

The method of using the brush has the effect of preventing the closing of the net certainly, but it rotates in contact with the contact and the wear rate is high due to the high wear rate.The brush is an expensive consumable and the 1m brush is maintained at about 80,000 won per piece. There was a high cost disadvantage.

In addition, the method of hitting with a metal rod is not a preferable solution because the noise is very high during the hitting process, making it difficult to work near the city center, and the screening network is damaged during the hitting.

The present invention solves the problems of the conventional network closure prevention device, and effectively prevents the network from being closed by soil or aggregates when sorting waste or aggregate, and can economically configure the device and easily exchange it when consumed. It was devised to present a network closure prevention device of usable structure.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a state diagram in which the present invention is installed in a waste sorter, and FIG. 2 is a perspective view of a configuration of the present invention, and the present invention is one side upper frame 12 of the sorting network 11 constituting the sorter 10. Install a support 21 protruding upward on the support shaft, and fix the rotary shaft 22 on the support member, couple the striking member 23 of rubber material at a predetermined interval on the rotary shaft, and the motor 24 to the rotary shaft. ), The rotating shaft rotates and the striker of the rubber material hits the sorting network, and has a structure that continuously shakes off the foreign matter attached to the sorting network.

The sorting machine applied to the present invention supports a cylindrical sorting net 11 that rotates as a waste sorting or aggregate sorter having a structure for sorting small-scale soil or sand from garbage or raw aggregates by a rotating sorting net, and a sorting net. The frame 12, the aggregate discharge port 13 formed in the lower portion of the sorting net and the aggregate discharge port 14 formed in the rear of the sorting network is provided.

The sorting machine sifts the aggregate or trash supplied through the feeding device 15 or the conveyor belt by a cylindrical rotating sorting network, and the small-sized soil or aggregate is discharged to the outlet 13 of the lower part, and passes through the net. Large-sized aggregates or trash that cannot be discharged are discharged to the outlet 14 at the rear of the screening network to separate small-sized aggregates and trash or large aggregates from waste such as trash, or to mix aggregates of various sizes. Consists of separating and sorting small sized aggregates.

Support 21 is to support the rotary shaft 22 is formed on the upper end of the hopper to support both ends of the rotary shaft, if the rotary shaft is long by installing 2-3 intermediate supports 21 'between both supports By allowing the axis of rotation to pass through the support it is possible to prevent the vibration of the axis during rotation.

Both ends of the support and the intermediate support and the rotating shaft is coupled by the bearing element so that the rotation of the shaft can be made smoothly, and the space between the rotating shaft and the upper surface of the frame so that the height of the rotating shaft support from the top of the frame to at least 30cm or more In this way, it is possible to pass through the space between the rotating shaft and the frame while bending the impact table to some extent.

The striking rod is a structure that is fixed to the rotating shaft after winding one end on the shaft using a rubber band (or rubber rope, rubber belt) made of tough and flexible material, and has an interval of 30-40cm to have a length of 40-60cm according to the diameter of the screening net. It is installed and wound in one end of the striking rod on the rotating shaft so that it can be easily exchanged when worn.

When the motor is driven by the above configuration, the blower coupled to the rotating shaft rotates to blow off the foreign matter such as soil and vinyl attached to the sorting network by hitting the sorting network as shown in FIG. 3.

The batting stand is made of flexible and tough rubber material so that even if the screening net is priced, it can effectively shake off the soil that is blocking the screen without damaging the screening net or severely impacting the screening net. Will be.

In case of partial damage, it is easy to maintain and replace only the damaged part, and low-cost materials such as rubber ropes and rubber belts are easily used as striking pads. Can be reduced.

The above devices can be installed on the left or right side of the sorting network without limitation and can be installed at the left and right sides of the sorting network at the same time. It is possible to operate effectively by determining the rotational direction of the motor to rotate in the direction.

The present invention by the above configuration is economical by constructing the striking stand using a rubber belt or rope, it is possible to replace and install the striking stand directly in the field, and the noise by shaking the soil by the striking stand made of a flexible rubber material There is no effect, such as preventing damage to the sorting network.
