Abstract

The name of the invention is an automatic slag discharger for turbid water filtration, which belongs to the field of water supply engineering. It includes reducer, reducer shaft, rotary scraping strip, long fiber brush, filter slag removal plate, filter screen, slag collection and discharge tank, clean water outlet, clean water room, bracket, water supply pipe, muddy water room, drain Slag hole, slag discharge pipe, sewage solenoid valve, solenoid valve switch signal transmitter, etc. After the turbid water containing solids flows from the inlet of the water supply pipe through the filter screen, the solids in it are intercepted by the filter screen and the residue on the filter screen is brushed into the slag collection tank by the rotating scraping bar and long fiber brush, and is discharged. The sewage is automatically washed away, thereby playing the role of automatic slag discharge for turbid water filtration.

Description

Turbid water filter automatic slag-draining device

Technical field;

The title of patent of the present invention is: turbid water filter automatic slag-draining device, belong to the water supply project field, when the muddy water that is mixed with solid content is flowed through turbid water filter automatic slag-draining device, screen pack can automatically filter out solid content and be arrived the collection ash pit by brushing, wash away from the flushing cinder hole that its excircle is opened, and the clean water through screen pack is just supplied toward the user.

Background technology:

The Congjiang, river, lake, marine water intaking at present all contains certain solid content, and these solid contents generally are that this just requires bigger processing place and numerous and diverse operating process, time-consuming, effort, expensive by Da Chi precipitation, filtration treatment; The machine of deterring of Mr.'s Sun Dexing invention is taked moment backwash method, has solved the line clogging etching problem, but its structure is not only complicated, also must increase a backwashing pump, reductor and corresponding valve.

Goal of the invention:

In order to remedy above-mentioned deficiency of the prior art, it is a kind of simple in structure, easy for installation that patent of the present invention will provide, and utilizes current and gravity just can finish the turbid water filter automatic slag-draining device of the automatic fitration automatic slag removal of muddy water.

Summary of the invention:

Parts such as reductor, reductor rotating shaft, rotary scraping and brushing bar, long fibre hairbrush, filter cleaner plate, screen pack, collection ash pit, pure water inlet, water purifying chamber, support, feed pipe, muddy water chamber, mud hole, scum pipe, blowdown magnetic valve, electromagnetic valve switch signal transmitter are assembled, make feed pipe and muddy water chamber UNICOM and affixed, the muddy water chamber connects mutually with the filter cleaner plate and fan-shaped screen pack is housed on the filter cleaner plate, and the lower edge of screen pack tightens the collection ash pit of knot trapezoidal cross-section.Filter cleaner plate bottom and concrete mutually UNICOM of water purifying chamber are consolidated with pure water inlet on the water purification locular wall, and support also is equipped with in the water purifying chamber bottom.Reductor is contained in top, muddy water chamber, loam cake Shen, muddy water chamber is passed in the reductor rotating shaft, and to go into muddy water indoor, and it is fixed with the rotary scraping and brushing bar, make the also coaxial rotation of energy on same axial line of rotary scraping and brushing bar, muddy water chamber, rotating shaft center, the rotary scraping and brushing bar is settled downwards and is fixed with the long fibre hairbrush, the top of this long fibre hairbrush contacts with screen pack, the edge of filter cleaner plate disconnects, tie mutually with water purifying chamber top, it promptly is the collection ash pit that trapezoidal cross-section and recessed groove are installed on the edge that the filter cleaner plate disconnects.Have the flushing cinder hole on the end water purifying chamber wall of collection ash pit, several flushing cinder holes are with blow-off pipe and back and the blowdown magnetic valve UNICOM that links together.When muddy water flows to user through water purifying chamber from pure water inlet through screen pack after feed pipe flows into the muddy water chamber.The hairbrush that the solid content of being held back by filter screen can be rotated sweeps in the collection ash pit, and when the electromagnetic valve switch signal transmitter that is equipped with in the rotating shaft sent out the valve signal, the blowdown magnetic valve was promptly opened, and the solid content that the indoor muddy water of muddy water just will collect in the ash pit washes away.

Description of drawings:

Fig. 1. be turbid water filter automatic slag-draining device figure;

Fig. 2 is a filter cleaner plate schematic diagram;

Fig. 3 is the former schematic diagram that buries of collection ash pit and blow-off pipe, magnetic valve.

Wherein: the 1--reductor; The rotating shaft of 2--reductor; 3--rotary scraping and brushing bar; 4--long fibre hairbrush; 5--filter cleaner plate; The 6--screen pack; 7--collection ash pit; The 8--pure water inlet; 9--water purifying chamber; The 10--support; The 11--feed pipe; 12--muddy water chamber; The 13--mud hole; The 14--scum pipe; 15--blowdown magnetic valve; 16--electromagnetic valve switch signal transmitter.

After muddy water flows into muddy water chambers 12 from feed pipe 11, see through screen pack 6, go out from water purification through water purifying chamber 9 Mouth 8 flows to the user. Be filtered the solid content that net 6 is held back. When reductor 1 drives reductor rotating shaft 2 rotation, Can be swept in the collection ash pit 7 by the long fibre hairbrush 4 of the rotary scraping and brushing bar 3 that connects on it. In the reductor rotating shaft When the electromagnetic valve switch signal transmitter 16 that is equipped with on 2 sent out the valve signal, blowoff electromagnetic valve is namely opened, and was turbid The solid content that muddy water in the hydroecium 12 just will collect in the ash pit 7 washes away.

Embodiment:

Accompanying drawing 1 also is the turbid water filter automatic slag-draining device structure chart that uses on the 580kW river source source pump.After muddy water flows into muddy water chambers 12 from feed pipe 11, after seeing through screen pack 6 and becoming clear water, flow to the user from pure water inlet 8 through water purifying chamber 9.When reductor 1 drives reductor rotating shaft 2 rotations, drive the rotary scraping and

brushing bar

3 and 4 rotations of long fibre hairbrush that connect on the deceleration arbor 2, the solid content that screen pack 6 is held back sweeps in the collection ash pit 7.Electromagnetic valve switch signal transmitter 16 also is housed in reductor rotating shaft 2, can send magnetic valve open and close signal when it rotates, blowdown magnetic valve 14 is promptly opened, or closes, muddy water in the muddy water chamber 12 just will collect closes again after ash pit 7 interior solid contents wash away, to reduce the sewer consumption.
