Description

[Detailed Description of the Invention] The present invention relates to a washing and sorting device for cleaning materials such as sand, which is used to purify sewage and the like.

The materials traditionally used to purify wastewater are:
If used for a long period of time, the particle size will become smaller and dirt will accumulate around the material, reducing the purification efficiency.
Generally, at this stage, the old item was discarded and replaced with a new item, without the old item being recycled or reused. However, unlike ordinary materials, these purification materials are produced in limited areas, have limited resources, and must be purchased accordingly, making it extremely uneconomical to dump them each time.

This invention focuses on resource issues and economic efficiency, and makes it possible to reuse materials whose purifying ability has decreased due to long-term use by cleaning them and sorting them into particles of a certain size. This is what we are trying to achieve.

To explain the example shown in detail below, first, at the right end of the frame 1 (FIG. 1), a rotating shaft 4 with crank disks 5, 5 fixed to both ends is horizontally mounted,
A belt 3 is stretched between the pulley 4' on the rotating shaft 4 and a prime mover 2 (reduction motor) installed directly below the pulley 4', and the rotating shaft 4 is rotated at a required speed by driving the prime mover 2. On the other hand, the washing frame 10 is tilted and suspended approximately at the center of the frame 1 by two pairs of hanging support rods 11, 11, 11', 11' which are freely expandable and contractible on all four sides. In addition, the hanging support rods 11, 11, 11', 11' are connected at their upper and lower portions by turnbuckles 12, 12, 12', 12', etc. approximately in the middle, and each Hanging support rods 11, 11, 11', 11' and frame 1
and a connecting portion with the washing frame 10 is pivotally supported to freely swing,
Furthermore, a material receiving tray 7 having an inclined portion 8 is set on the right end of the upper surface of the washing frame 10, and a 9 is placed on the front extension of the material receiving tray 7, so that the materials shaken out from within the material receiving tray 7 are successively placed on the 9. The right end of the washing frame 10 and the side eccentric position of the crank disks 5, 5 are connected by a connecting rod 6, and the upper part of the washing frame 10 is connected to the right end of the washing frame 10. A water nozzle 1 is attached to a water supply pipe 13 that runs along the extension direction of the washing frame 10.
4, 14, etc. are provided in the required number sequence.

The present invention is constructed as described above.Next, the operation and effect of the invention will be described.The prime mover 2 normally uses an electric motor, and its output rotational speed is reduced to the required rotational speed, and the belt 3 By driving the pulley 4' on the rotating shaft 4 through the rotary shaft 4, the crank discs 5, 5 at both ends of the rotating shaft 4 are rotated, and the oscillating motion on the crank disc 5 is generated via the connecting rod 6. is transmitted to the washing frame 10. That is, since the attachment points of the connecting rods 6 to the crank disks 5, 5 are outside the rotation center of the crank disks, the connecting rods 6 vibrate, and the washing frame 10 is attached to each of the hanging support rods 11, 11 and 11 as shown by the arrows. ',1
1' and swings.

Therefore, prior to this operation, the untreated materials stored in the material receiving tray 7 are rubbed against each other by water poured from the faucet 15 and rocked, and the dirt adhering to the surface is rubbed off. While washing,
Due to repeated rocking, the material is gradually thrown out from the slope part 8 together with the water accumulated in the saucer 7, moves onto the top 9, and receives water from the water nozzle 14. The particles fall through the eyes and fall to the lower part, where they are carried out and removed by a conveyor (not shown) or the like at any time.

Thus, only the material having a certain particle size is fed to the final position at the left end of the cleaning frame 10.

In addition, if the material is difficult to come out from the material receiving tray 7 or if the upper surface does not move well, the turnbuckles 1 of the hanging support rods 11, 11, 11', 11'
2 and 12' to adjust the inclination angle of the tray 7. If further cleaning is required, use frame 1.
A frame 16 is added to the left end of the frame 1, and a similar washing frame 1 is installed.
7 are connected at the end 18, it is possible to perform several stages continuously, and the water used here is collected and returned to the upper fountain nozzle for repeated reuse. Note that chemicals are also added as appropriate from the top.

In this way, by swinging the washing frame, the present invention allows the material to be ejected little by little from inside the material receiving tray using the vibration acceleration and the water poured into the receiving tray.
〓Even on the top, it will not be washed away instantly,
Since it is sent out gradually, there is enough time for washing with water, and during this time, it is possible to reliably remove dirt while distributing microscopic dirt.It is also possible to save resources by reusing it, and the structure is also improved. It is an economical idea that can be provided easily and at low cost.
