Description

Long-distance sludge discharging device

Technical Field

The utility model belongs to the technical field of the water treatment technique and specifically relates to an easy operation, but long distance mud discharging device of accurate control, the region that all needs to arrange mud is all suitable for.

Background

At present, in a conventional water purification process, a flocculation section and a transition section of a flocculation tank are both provided with sludge discharge pipes for sludge discharge, the area is a crucial item of a water treatment process, and a large amount of impurities and alum flocs in water are precipitated in the section by an external coagulant.

Generally, the sludge discharge system in the region is characterized in that a perforated sludge discharge pipe or a sludge discharge hopper is arranged at the bottom of a pool, and under the action of the static pressure of water, sludge is simultaneously fed into all sludge discharge ports and is discharged through the sludge discharge pipe. It is not ideal to find in production practice, this kind of arrange mud mode arrange the mud effect, has to arrange the unsmooth and local short condition of flowing of mud, arranges mud thoroughly inadequately, and long-time hindrance that will aggravate the mud of arranging of bottom of the pool, mud pipe simultaneously, arranges mud effect relatively poor. This arrange mud mode water yield is extravagant great, and the personnel on duty need often pause system water and carry out the desilting, and this also causes certain economic loss, and the pond body of unloading simultaneously carries out long-pending mud desilting work, and is very troublesome, and workman desilting intensity of labour is big.

Disclosure of Invention

An object of the utility model is to design a regional row's mud mode and pipeline control system of water purification flow row mud, it is heavier to consider flocculation basin row mud burden, the long-pending mud condition is serious, to the characteristics of current situation row mud system, compromise automatic control, reduce displacement and manual management cost requirement, the row mud system of design adopts pneumatic valve control mud discharge opening row mud order, and install ultrasonic sludge interface detector on the pool wall guide rail, also realize the control to the long-pending mud height in whole pond bottom of the pool, the long-pending mud problem of solution bottom of the pool that finally can be better.

The technical scheme of the utility model is that: the utility model provides a long distance mud discharging device, this long distance mud discharging device includes the mud pipe, be equipped with the mud discharging port on the mud pipe, install a pneumatic valve alone additional at every mud discharging port, pneumatic valve's actuating mechanism links to each other with the air-pressure pipe, the air-pressure pipe upwards passes the pond top along cell body inner wall simultaneously, be connected to outside pneumatic valve control box along the cell body outer wall, pneumatic valve control box includes low-voltage solenoid valve and gas-water separator, ultrasonic wave mud interface detector is installed on the slider, the slider slides on the guide rail of cell wall.

The pneumatic valve on each sludge discharge port is independently opened.

The utility model has the advantages that: the ultrasonic sludge interface detector is arranged on a sliding guide rail on the inner side of the tank wall, and the guide rail is dragged, so that the sludge surface detection range can be expanded, and long-distance full-coverage detection is realized; according to the detection conditions of the accumulated mud in different areas, a plurality of mud discharge ports are selected for discharging the mud, especially when a mud discharge pipe is long, the conditions of congestion and short flow during mud discharge are effectively reduced, the mud discharge efficiency is improved, and the mud accumulation phenomenon is greatly reduced; the sludge discharge system has the advantages of simple structure, simple and convenient operation, small water discharge and good sludge control effect. The PLC point positions can be increased on the site under the condition, the control of a pneumatic valve of a sludge discharge port and the ultrasonic sludge interface detector are brought into automatic control, and automatic remote control can be realized; the long-distance sludge discharge device can be used for the transformation of old water plants and can also be used for newly-built water plants.

Detailed Description

The utility model provides a long distance mud discharging device, this long distance mud discharging device includes long distance mud pipe 1, install a pneumatic valve 2 alone additional at every mud discharging port 6, pneumatic valve's actuating mechanism 8 links to each other with air-compressed pipe 3, air-compressed pipe 3 upwards passes the pond top along the cell body inner wall simultaneously, be connected to outside pneumatic valve control box 4 along the cell body outer wall, the controller includes low-voltage solenoid valve 5 and gas-water separator 7, ultrasonic wave mud interface detector 10 is installed on slider 12 simultaneously, slider 12 slides on the inboard sliding guide 11 of cell wall

Each pneumatic valve is respectively controlled by an external solenoid valve 5, and the pneumatic valve 2 on each sludge discharge port can be independently opened and discharges sludge to a sludge discharge channel 9 through a sludge discharge pipe. The mud accumulation conditions of different areas of the water tank are monitored in real time through the ultrasonic mud interface detector, and then each mud discharging port is selectively opened independently or in a combined mode to perform accurate mud discharging.

The pneumatic valve 2 is a pneumatic gate valve of DN 100.

The air pipe 3 is a stainless steel pipe DN25, and the length is actually determined on site. Two ends of the stainless steel pipe are respectively connected with an external pneumatic valve controller and an internal pneumatic valve through rubber hoses, and the caliber length of the rubber hoses is determined according to the pneumatic valve controller selected for use.

The pneumatic valve controller 4 comprises a DN15 electromagnetic valve and a matched gas-water separator.

The low-voltage solenoid valve 5 is a 24V DC two-position four-way solenoid valve.

The sludge interface detector 10 is an ultrasonic sludge interface detector.

The sliding guide rail 11 is made of channel steel and a sliding groove on site.
