Abstract

The invention relates to hydraulic engineering, in particular, to structures for complex water purification from sediments and debris during water intake into an irrigation network. The purpose of the invention is to increase the efficiency of the facility in operation. Water along with sediments and mu-stream flows through the transit channel 3, where debris and sediments s with dimensions larger than the lumen of the vibrating grids 4 are retained on the vibration grid 4 and transported further along channel 3. A part of the water with sediments smaller than the vibratory grid clearance 4, through the bottom slit enters the supply conduit 1 into the spiral chamber 13, which has slots closed with a grid 19. In this case, part of the water with sediments and debris with dimensions larger than the mesh size 19, through the washing hole in the bottom of the spiral chamber 13 along the washing tr pipeline 17 is transported to the downstream. The clarified water from the spiral chamber 13 is collected by the collector 20 and flows through the discharge channel 21 to the consumer. 6 Il. SS

Description

The invention relates to hydraulic engineering, in particular, to structures for complex water purification from fin, debris, drawn and part, suspended sediment during water intake into an irrigation network.

The aim of the invention is to increase efficiency in operation.

The water intake purification facility consists of a supply conduit 1, the initial section of which coincides with the bottom slit 3 in, not the transit channel 3, blocked by the vibration grid 4 with the location of its long part across channel 3 and with an inclination opposite to the flow, and the front restricting rod 5 of the vibration grid 4x is connected the hinge 6 with the bottom of the channel 3, and the rear limiting rod 7 of the vibrating grid 4 rests on the elastic elements 8 attached in the transverse groove 9. arranged at the bottom of the channel 3, narrowed by petssrA

The transitional suit 10 of the supply channel 3 has a height h and width E, and the main part 11 has a height hy and width b%, and the height of the main part 11 of the supply conduit 1 is assigned to the A3 inequality b. / 2 h, and the width of the main part 11 inlet Channel 1 is assigned from the inequality, 67E, diffuser 12, whose inlet JQ cross section is connected to the main part 11 of the supply conduit 1, and the output cross section mates tangentially with the spiral chamber 13, the spiral chamber 13 with the overflow transverse groove 9 in the bottom of the channel 3,

through the narrowed transitional part 10 of the supply conduit 1 to the main part 11 of the supply conduit The rest of the water, along with fin, debris, drawn sediment (and an insignificant part) of sediment, the characteristic size of which exceeds the size of the cell of the vibrating grid C, goes downstream of the transit channel 3, due to the oscillatory movements of the rear limit rod 7 of the vibrating grid 4 on the elastic elements 8, which are melted

 And spiral-in-line outlines with a maximum Kmade radius at the exit to the spiral chamber 13 and height H (/; conical bottom 15 with a washing hole 16 of radius g05 in the 20 entrance to the washing line 17, and the Rounding radius of the washing line 17 is selected, conditions for ensuring a smooth transition from the vertical orientation of the pipeline 17 to an orientation close to horizontal (see Fig. 5), but with a slope ensuring the transport of the washing water flow along with all the external inclusions, and in the upper part the overflow wall 14 of the spiral chamber 13 has secured elements in the form of vertical slots 18, which are covered by each high-strength and finely cellular nylon mesh 19, and the spiral chamber 13 is overlapped on top also by a stretched high-strength and finely cellular nylon mesh 19, along the perimeter of the spiral chamber 13 in the upper part, a collector 20 is provided in the form of an annular tray for collecting clarified water, a discharge channel 21 of clarified water.

Water intake cleansing works as follows.

Water, along with the flute contained in it}, drawn and suspended sediments flows through the transit channel 3. On the vibrating grid k, the first division of the flow occurs. Part of the water, along with fin, debris, drawn and suspended sediments, the characteristic size of which does not exceed the size of the vibration grid k, passes through the useful clearance of the vibration-. rosettes kt bottom slot 2 at the bottom of the transit channel 3 (initial section of supply conduit 1), post 35

around the front limiting rod 5 of the vibrating grid k, a hinge 6 connected to the bottom of channel 3.

The water along with the fin, the trash part of the drawn sediments and suspended sediments, the characteristic size of which does not exceed the size of the vibro-grid cell, the passage through the diffuser 12, enters the spiral chamber 13 in a tangential and smooth manner.

Here passes the second division of the current. Water along with fin, litter, drawn and suspended sediments, the characteristic size of which exceeds the cell size of a high-strength and finely cellular nylon mesh 19 stretched over the top of the spiral chambers 13, and the mesh of protective elements in the form of vertical slits 18s through a washing hole 16 in the conical bottom 15 of the spiral chamber 13 through the flushing line 17 is transported to the lower reach.

The clarified water, along with fin, debris and suspended sediments, the characteristic size of which does not exceed the cell size of the high-strength and finely cellular nylon mesh 19 stretched over the top of the spiral chamber 13, is collected by the collector 20 in the form of an annular tray to collect the clarified water and post into the discharge channel 21 of the reflected water to the consumer.

Based on the interconnection and interdependence of the main elements of the intake cleansing structure, the width of the transit channel 3 (E) and the maximum radius of the spiral chamber 13 (Rwiatr) are related by
