For convenience of description, the words "upper", "lower", "left" and "right" in the present application, if any, merely indicate correspondence with the upper, lower, left and right directions of the drawings themselves, and do not limit the structure, but merely facilitate the description of the present invention and simplify the description, rather than indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

Term interpretation section: the terms "mounted," "connected," "fixed," and the like in the present invention are to be understood in a broad sense, and may be, for example, fixedly connected, detachably connected, or integrated; the two components can be connected mechanically, directly or indirectly through an intermediate medium, or connected internally or in an interaction relationship, and specific meanings of the terms in the present invention can be understood by those skilled in the art according to specific situations.

Just as the background art introduces, the sand blown by the wind is great in spring and autumn two seasons, and the silt volume is more, and silt can't the interception behind the cement barricade, leads to circulating water turbidity to rise, and circulating water system need carry out the blowdown, causes the problem that circulating water system water consumption increases, for solving above technical problem, the utility model provides an open circulating water crosses water gallery silt discharging equipment.

As shown in fig. 1-3, the utility model discloses an embodiment has recorded an open circulating water gallery silt discharging equipment, includes: a collecting pipe 1, a discharging pipe 3 and an aeration pipe 2; the collecting pipe 1 sets up in the water passing corridor and with water passing corridor bottom 6 have the settlement distance, collecting pipe 1 has upstream end 12 and low reaches end 11, has collection hole 5 on the pipe wall, and collecting pipe 1's low reaches end 11 is connected discharge pipe 3, discharge pipe 3 follows water passing corridor bottom 6 is worn out downwards, connects aeration pipe 2 on the discharge pipe 3, and aeration pipe 2 is used for carrying out the back flush to the aeration in the collecting pipe 1. The aperture of the collecting pipe 1 is 90-110mm, and the collecting hole 5 is 3-5mm.

Utilize when water corridor interior silt will surpass the cement barricade the utility model discloses a discharging equipment arranges husky, and the mixture of the silt of water corridor bottom and water gets into the collecting pipe through the collecting hole and discharges along the delivery pipe, reduces the interior silt volume of water corridor, has solved water corridor silt deposit, the problem that can't discharge to reduce the circulating water turbidity, further reduced the consumption of circulating water. When silt blocks up the collecting hole, aerate through the aeration pipe, carry out the back flush to the collecting pipe, then can show after a large amount of bubbles in collecting hole that the collecting hole has been dredged, solved the problem that the collecting hole blockked up through setting up the aeration pipe.

A sand discharge valve 7 is arranged on the pipeline of the discharge pipe 3, and the sand discharge valve 7 is positioned at the lower part of the connection point of the aeration pipe 2 and the discharge pipe 3; and a flushing valve 8 is arranged on the pipeline of the aeration pipe 2. When the sand is required to be discharged, the sand discharging valve is opened, and the aeration valve is closed; when the collecting hole is blocked, the aeration valve is opened, the sand discharging valve is closed, and the sand discharging process and the back washing process are convenient to switch by arranging the sand discharging valve and the flushing valve.

The collecting pipe 1 is at a predetermined angle to the water gallery bottom 6, and the upstream end 12 is higher than the downstream end 11. The collecting pipe is arranged to be higher than the downstream end at the upstream end, so that a certain slope is formed in the collecting pipe, and silt is conveniently discharged.

The flow direction of the silt in the collecting pipe 1 is the same as the flow direction of the water in the water passing gallery. The flow direction of circulating water is from right to left in figure 1 promptly, sets up to the same through the flow direction with silt and the rivers direction in the water channel, utilizes rivers to promote the flow of silt in the collecting tube, makes silt flow more smoothly, reduces the condition that the collecting hole blockked up.

The upstream end 12 of the discharge pipe 3 is terminated by an end cap 13 (fig. 3), and the end cap 13 is provided with a collection hole 5. Through set up the end cover at the delivery pipe terminal surface, set up the collection hole on the end cover, prevent that a large amount of silt from flowing into in the collection pipe fast, reduce the probability of blockking up the collecting pipe. On the other hand, if the collecting hole is designed to be open, when the collecting hole is blocked for aeration, gas is directly blown out from the opening at the upstream end of the collecting pipe, so that the collecting hole is difficult to dredge, and the backwashing effect is greatly reduced.

And the bottom of the discharge pipe 3 is connected with a wastewater tank 4, and the wastewater tank is used for storing discharged silt.

The collecting pipe 1, the discharging pipe 3 and the aeration pipe 2 are all made of metal materials, so that the service life of the discharging device is prolonged.

The working principle is as follows: silt enters the collecting pipe 1 through the collecting hole 5, when the collecting pipe is used, the silt discharging valve is opened, the mixture of the silt and water is discharged into the wastewater tank 4, and after the silt is discharged completely, the silt discharging valve is closed; when the collecting hole 1 is blocked by silt in the collecting pipe, the flushing valve is opened, the collecting pipe 1 is backwashed, after the collecting hole 5 bubbles in a large amount, the flushing valve is closed, the sand discharging valve is opened, the mixture of the silt and the water is discharged into the wastewater tank 4, and after the silt is discharged completely, the sand discharging valve is closed.

The embodiment still provides a circulating water system, including crossing water corridor, the aforesaid is installed to the water corridor open circulating water crosses water corridor silt discharging equipment. Because the silt discharging apparatus has the above technical effects, please refer to the above embodiment for the technical effects of the circulating water system using the silt discharging apparatus.

Although the specific embodiments of the present invention have been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and it should be understood by those skilled in the art that various modifications or variations can be made by those skilled in the art without inventive efforts on the basis of the technical solutions of the present invention.
