Hydraulic engineering filter pipeline with filter screen

Technical Field

The utility model relates to a hydraulic engineering field, concretely relates to take hydraulic engineering filter tube way of filter screen.

Background

Hydraulic engineering is an engineering built for controlling and allocating surface water and underground water in nature to achieve the purposes of removing harmful substances and benefiting. Also known as water engineering. Water is a valuable resource essential for human production and life, but its naturally occurring state does not completely meet the needs of human beings. Only when hydraulic engineering is built, water flow can be controlled, flood disasters are prevented, and water quantity is adjusted and distributed to meet the requirements of people on water resources in life and production. Hydraulic engineering needs to build various types of hydraulic buildings such as dams, dikes, spillways, water gates, water inlets, channels, transition troughs, rafts, fishways and the like so as to achieve the aims. In the implementation of hydraulic engineering, the hydraulic pipeline is an integral part.

Most water conservancy pipelines do not have the effect of filtering or clearing up debris. Therefore, after long-term use, the water conservancy pipelines face the condition that the drainage efficiency is low or the water cannot be drained completely due to sundries blockage. Patent number CN201920127513.7 a water conservancy pipeline for hydraulic engineering mentions about the mode of filtering debris and solves the problem that prevents the water conservancy pipeline jam among the prior art, and what this technique adopted is that the inboard left end of trunk line is provided with grit processing storehouse, and grit processing storehouse right side is provided with silt and handles the storehouse, and silt is handled the storehouse right side and is provided with the desilting device, and trunk line right-hand member top is provided with the drain pipe. However, this technique has certain disadvantages, such as that after a period of filtration, the water flow rate is slowed down due to excessive impurities in the filter. And the device has complex design structure and high cost. Therefore, a device with simpler structure, low cost and more excellent filtering and anti-blocking effects is needed.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Referring to fig. 1-3, a hydraulic engineering filter pipe with filter screen, including inlet channel 1, filter pipe 2, drainage pipe 3 and first filter screen 5, inlet channel 1 and drainage pipe 3 are connected respectively to filter pipe 2 both ends, first filter screen 5 sets up in filter pipe 2, filter pipe 2 is for erectting the setting, first filter screen 5 slope sets up, collect box 4 and set up in the filter pipe 2 outside of the lower one end of first filter screen 5 horizontal position, the filter pipe inner wall of both sides all is equipped with through-hole 6 about the lower one end of first filter screen 5 horizontal position, collect box 4 and through-hole 6 intercommunication, through-hole 6 below first filter screen 5 still is equipped with second filter screen 7. During operation, rivers that have debris get into from inlet channel 1, when rivers that have debris pass through filter tube 2, the first filter screen 5 that sets up in filter tube 2 can filter debris, and most rivers can flow from first filter screen 5, because first filter screen 5 is the slope setting, therefore a little rivers can flow to lower one end from first filter screen 5 higher one end slightly, wash the debris on first filter screen 5 in through-hole 6 above first filter screen 5 to collect box 4, through-hole 6 below first filter screen 5 still is equipped with second filter screen 7, and the little rivers that get into in collecting box 4 can flow into filter tube 2 once more through second filter screen 7 in, and debris can be intercepted by second filter screen 7. The water flow after being filtered impurities flows into the drainage pipeline 3 from the filtering pipeline 2 and is discharged from the drainage pipeline 3.

Collect box 4 including collecting box bottom plate 13, collect box bottom plate 13 and be detachable construction, collect box bottom plate 13 one end and collect box 4 articulated, the other end integration shaping is equipped with lug 14, lug 14 passes through

bolt

15 and 2 outer walls of filter tube and fixes. When sundries need to be cleaned, the sundries in the collecting box 4 automatically fall down due to the influence of gravity only by loosening the bolts 15 on the convex blocks 14 to open the collecting box bottom plate 13, so that the sundries are very convenient to clean. The collecting box bottom plate 13 is arranged in a downward inclined manner, and one end connected with the filtering pipeline 2 is the lower end in the horizontal position. This allows a better guidance of the water flow inside the collecting box 4 into the filter conduit 2. Of course, the first filter 5 and the second filter 7 can also be serviced through the through hole 6 by opening the collecting box bottom plate 13.

The bottom of the first filter screen 5 is also provided with a support frame 16, and a plurality of support arms 17 are distributed between the support frames 16. Because the first filter screen 5 is firstly impacted by water flow and sundries carried in the water flow, the middle of the filter screen is sunken after the first filter screen is used for a period of time, the sundries are accumulated at the sunken position, the filtering effect is reduced, the flow rate of the water flow is slow, and the like. And set up support frame 16 in first filter screen 5 bottom, still distribute a plurality of support arm 17 between support frame 16, just so can keep first filter screen 5 indeformable sunken under the impact of long-time rivers, make first filter screen 5's life longer.

The utility model discloses a filter pipeline 2 still includes water-stop sheet 8, and water-stop sheet still is equipped with sealing washer 10 along 9 outward, and the inlet tube top is equipped with can hold 8 male openings 11 of water-stop sheet, and opening 11 top is equipped with detachable dirt protector 12. When cleaning up the debris or maintaining first filter screen 5, if the rivers of inlet channel 1 do not stop, can cause very big obstacle to cleaning up the debris or maintaining the filter screen (in fact the applicant is using this pipeline, general rivers can't all fill up the inlet channel when the drought and waterlogging season every year, and most rivers are about half at the inlet channel in this season, and it is the best to select this season to clean up the first filter screen of maintenance this moment in this year). Consequently can be through opening antifouling cover 12, insert rivers completely cut off in the inlet channel 1 with water-stop sheet 8, and set up and then can isolate the rivers better along 9 sealing washers 10 outside the water-stop sheet, prevent that the less part rivers from flowing out from the gap, influence clearance debris etc..

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
