Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sheath transport device, and more particularly to a sheath transport device for transporting the sheath generated at a pumping station or a sewage treatment plant to a cleaning facility or a dewatering facility.
[0002]
[Prior art]
Contaminants such as water generated at pumping stations and sewage treatment plants have a high water content, are unsanitary, and are difficult to handle, so they are disposed of after being washed and dehydrated. Such strength is scraped up from the water by a dust remover and then sent to a thickness cleaning facility or a dehydration facility by a conveying device such as a belt conveyor.
[0003]
[Problems to be solved by the invention]
However, in the combined sewer system, large blocks such as stones, concrete blocks, metal pieces, etc. may flow along with water when it rains, so these blocks are also washed up with a dust remover and washed. It will be transported to equipment and dehydration equipment. Such a lump has a great influence on the cleaning equipment and the dewatering equipment, and in particular, stones and large metal pieces can cause damage to the machine.
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to provide a mass transfer device capable of automatically separating and removing a lump that adversely affects a cleaning facility and a dehydration facility.
[0005]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the margin conveying device of the present invention connects a lump separating tube for dropping lump mixed in the lump to the bottom of the conveying path for conveying the lump, and the bottom of the lump separating tube In addition, a lump collection chamber is continuously provided, and a separation water supply unit is provided for flowing the lump separation water upward from the lump separation tube toward the conveyance path.
[0006]
Furthermore, a screen for water separation is provided in the conveyance path downstream from the lump separation pipe connecting portion, and a pump for supplying water separated by the screen as the lump separation water is provided.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a schematic cross-sectional view showing one embodiment of the edge conveying device of the present invention. The sheath conveying device 10 is formed so as to convey the sheath 12 by the hollow screw conveyor 11, and the sheath 12 scraped up by the dust remover is a hopper provided at the conveyor end from the conveyor inlet side 11a. 13 to the cleaning equipment.
[0008]
A lump separation tube 21 for dropping lumps 15 mixed in the sheath is connected to the middle part of the hollow screw conveyor 11 at the lower part of the pipe forming the conveying path 14 of the hollow screw conveyor 11. ing. The lump separation tube 21 is composed of a pipe having a diameter sufficient to drop the lump 15, and a lump collection chamber 22 for collecting the separated lump at the lower end thereof. Is provided. The lump collection chamber 22 is provided with separated water supply units 23 and 24 for supplying lump separated water as an upward flow into the lump separation tube 21.
[0009]
Since the lump separating tube 21 and the lump collecting chamber 22 are formed in a state where only the connection portion with the transport path 14 is opened, the lump collecting chamber 22 is separated from the separated water supply units 23 and 24. The separated water supplied into the interior rises in the lump separation pipe 21 and flows into the conveyance path 14. Then, the flow rate of the separation water in the lump separation tube 21 is set to such an extent that the lump 15 such as a stone or a metal piece falls in the lump separation tube 21 but the margin 12 hardly falls. 12 and lump 15 can be separated.
[0010]
That is, the lump 15 mixed in the way of being transported to the connection portion of the lump separation tube 21 falls toward the lump collection chamber 22 by its own weight against the upward flow 25 of the separation water, There is almost no drop, and only the lump 15 is separated from the lump 15 in the middle of dropping by flowing the separated water at a flow rate that can be raised into the conveying path 14 by the upward flow 25. Can be separated and collected in the lump collection chamber 22.
[0011]
Thereby, the lump 15 is not transported to the cleaning facility or the dehydration facility, so that it is possible to reliably clean and dewater the tail 12 in these facilities and to prevent the machine from being damaged. The lump 15 in the lump collection chamber 22 is taken out from the door provided in the lump collection chamber 22 by draining the water in the lump separation chamber 22 at an appropriate time.
[0012]
Furthermore, in this embodiment, the separated water is discharged from the screw conveyor 11 and reused in case the amount of washing water used in the washing facility is limited or when the separated water cannot flow downstream. A route to use is also provided. That is, a screen 31 is provided in the conveyance path 14 on the downstream side of the lump separation pipe 21, and excess water is recovered from the separation water recovery pipe 32 to the water tank 33 through the screen 31, and the separated water in the water tank 33 is recovered. A pump 34 is used to circulate and supply the separated water supply unit 24. In addition, by using a wedge wire screen with the direction of the wedge as the conveying direction, the screen 31 hardly affects the conveyance of the edge 12, and clogging of the screen hardly occurs.
[0013]
In addition, the lump 15 that has fallen into the lump collection chamber 22 is collected in a water-permeable material such as the cage 26, thereby easily removing the lump 15 from the lump collection chamber 22. be able to. Furthermore, by separating the separation water supplied from the separation water supply units 23 and 24 through the basket 26 onto the lump 15, the sticking to the lump 15 can be peeled off and returned to the transport path 14. Since the lump 15 can be washed, the generation of bad odors when the lump 15 is taken out is eliminated, and hygiene can be improved.
[0014]
In addition, even when conveying the strength with a flowing water trough or the like, it is possible to separate the lump in the strength by installing a lump separation tube or the like in the same manner as described above.
[0015]
【The invention's effect】
As described above, according to the margin conveyance device of the present invention, a lump that is mixed in the middle of conveyance can be automatically separated and removed.
