Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for dewatering and transporting solid materials such as sand, and particularly aims to provide a dewatering device suitable for application attached to a rotary classifier. This is the purpose.

The dewatering device of the present invention has solid material scraping blades arranged radially within the rotating drum, a discharging member for receiving and draining the solid material falling from the ceiling of the rotating drum, and At least a part of the circumferential drum is made of a ring-shaped elastic body, and a repetitive impact member or a repetitive impact member and a pressing member are provided on the elastic body to dehydrate the solid material in the lower part of the rotating drum. is provided, and the dehydrated solid material is configured to fall accurately to the discharge member at the upper part thereof.

An embodiment of the present invention will be described with reference to the drawings. A solid material supply port 18 is provided on one side wall of the rotating drum 1'.
A solid matter discharge port 19 is opened in the other side wall 17,
The center of the circumferential body of the rotating drum 1' is constituted by a ring-shaped elastic body, that is, an elastic ring 11, and solid material scraping blades 12 are provided on the inner peripheral surface of the elastic ring 11.
(for example, an elastic plate, a water-permeable steel plate such as a steel plate or a perforated plate) are arranged radially, and the solid matter that is scraped up to the ceiling by the scraping blades 12 and falls into the rotating drum 1' is received. A discharge chute 15 for later transferring the solids to the discharge port 19 is disposed, and an upper vibrating device 2 and a lower vibrator are installed directly above and directly below the elastic ring 11 as an impact member for repeatedly applying shocks to the elastic ring 11, respectively. A device 2' is provided.

The structures of these two vibrating devices are almost the same, but to explain the upper vibrating device 2, it consists of an oscillator 6 such as a vibrator, a frame 4, a bearing 5, a roll 3, a bolt 8, a spring 7, a nut 16, and a spring. It is formed from 7 fixing members etc.
The vibration of the oscillator 6 is caused by the frame 4 → bearing 5 → roll 3
→The elastic ring 11 is configured to be transmitted in this order.

The dewatering device of the present invention can perform the dewatering and discharging work of solid materials by itself by attaching a rotation drive device and a support member for the rotary drum 1'. It is extremely effective to use it in conjunction with the rotary classifier 1 as shown in FIG.
That is, in FIG. 5, the settled sand in the raw water is transferred to the ceiling by the raking blade 23 via the spiral blade 22, and then falls into the discharge chute 24, and is then transferred to the raking blade 12, 12 in the rotating drum 1'. Injected in between. Since the rotating drum 1' rotates integrally with the rotary classifier 1, the settled sand is transferred toward the ceiling of the rotating drum 1' by the scraping blades 12.
During this time, the repeated impact transmitted from the lower vibration device 2' to the elastic ring 11 at the bottom of the rotating drum 1' sufficiently dehydrates the elastic ring 11, resulting in a compact state. The settled sand transferred to the ceiling is firmly held between the raking blades 12 and 12, so it does not fall down as it is, but due to the repeated impact transmitted from the upper vibration device 2 to the elastic ring 11, it falls effectively and is discharged. It is discharged to the outside of the rotating drum through the chute 15.

In FIGS. 1 to 7, 9 is a side wall of the rotary classifier 1, and the rotating drum 1' is attached to and integrated with this side wall 9. 10 is rotary classifier 1
13 is a suspension frame, 14 is a handrail, 25 is a washing water supply pipe for washing settled sand, 26 is a floor, 27 is a step, 28 is a base, 2
9 is a support body including a buffer section. 13' ladder,
16 is Natsu.

In the embodiment, a hammering device or a pressing member may be provided in place of the upper vibrating device 2, or a hammering device may be provided in place of the lower vibrating device 2'.

As described above, the dewatering device of the present invention can effectively dehydrate and transport solid materials such as sand by itself. Once installed and used, it is easy to handle and extremely convenient.
