Description

Aeration accelerating device

Technical Field

The invention relates to the technical field of water treatment, in particular to an aeration accelerating device.

Background

As shown in figure 1, a traditional aeration device is characterized in that an aeration pipe 1 is connected with an aerator 2 and extends into a river channel, dissolved oxygen in river water is increased in the process of gas discharge by arranging a first gas discharge hole 1-1 on the aeration pipe 1, and the end part of the aeration pipe 1 is generally closed so as to prevent impurities from entering the aeration pipe 1 to block the gas discharge hole and prevent most of gas from directly overflowing from the end part. When the aeration device is closed, river water can gradually enter the aeration pipe 1 through the first exhaust hole 1-1, so that the air can be exhausted by firstly exhausting the water from the first exhaust hole 1-1 when the aeration device is opened every time, the first exhaust hole 1-1 which is close to the aerator 2 generally exhausts the air firstly and has larger air displacement, the first exhaust hole 1-1 which is far away from the aerator 1 exhausts the air later and has smaller air displacement because part of the water is retained in the aeration pipe 1, and the first exhaust hole which is 200m away from the aerator generally takes about 30 minutes to exhaust the air bubbles, so that the aeration device is slowly started and the working efficiency is lower.

Disclosure of Invention

Aiming at the problems of slow drainage and low working efficiency of the traditional aeration device, the invention provides an aeration accelerating device which is fast in starting and high in working efficiency.

The technical scheme is as follows: the utility model provides an aeration accelerating device, its aeration pipe including connecting the aeration machine, the aeration pipe is last to have seted up first exhaust hole, its characterized in that: the utility model discloses a three-way aerator, including aerator, first check valve and tee bend, the aeration pipe is kept away from the tip of aerator has connected gradually first check valve and tee bend, first check valve is used for preventing the fluid refluence and gets into the aeration pipe, the exhaust cover is installed at the tee bend top, the second exhaust hole has been seted up on the exhaust cover, the second check valve is installed to the tee bend bottom, the second check valve is used for the control fluid to flow out the tee bend, still be equipped with the body in the tee bend, the valve clack of second check valve is connected with through pulling the piece the body, works as the body is located when the tee bend is the top, the body passes through pull the piece and open the second check valve.

It is further characterized in that:

the lower end of the second check valve is provided with a filter screen;

the first check valve is connected with the tee joint and the tee joint is connected with the second check valve by welding or hollow pipes.

The beneficial effects of the invention are as follows: after opening the aeration machine, the long-pending water of staying in the aeration pipe can be hardly receive resistance ground and directly pass through first check valve discharge aeration pipe to can make gas run through whole aeration pipe fast and realize starting fast effect, and when the bubble is emerged to the first exhaust hole of furthest department, compare in traditional aeration equipment, the water of reserving in the pipe significantly reduces this moment, make the displacement of each first exhaust hole more even, improved aeration equipment's work efficiency.

Detailed Description

As shown in fig. 1, 2 and 3, the aeration accelerating device comprises an aeration pipe 1 connected with an aerator, a first exhaust hole 1-1 is formed in the aeration pipe 1, the end of the aeration pipe 1 far away from the aerator 2 is connected with a first check valve 3 and a drainage device 4, the first check valve 3 is used for preventing fluid from entering the aeration pipe 1, the drainage device 4 comprises a connecting pipe 4-1 (which can be an elbow) connected with the aeration pipe 1 and an inclined tee joint, the tee joint comprises a drainage part 4-3 which is vertically arranged and a communication part 4-2 which is used for connecting the side part of the drainage part 4-3 with the connecting pipe 4-1, each part can be bonded by hot melt or glue, the first check valve 3 is positioned in the connecting pipe 4-1, the communication part 4-2 is preferably arranged in an inclined manner, the communication part 4-2 is connected with the middle part of the drainage part 4-3, the top of the drainage part 4-3 is provided with an exhaust cover 4-31, if the upper end of the tee joint is shorter, a hollow pipe can be connected with the exhaust cover 4-31, the exhaust cover 4-31 is provided with a second exhaust hole 4-32, the bottom of the drainage part 4-3 is provided with a second check valve 4-33 and a filter screen 5, the second check valve 4-33 is preferably a swing check valve, the second check valve 4-33 is used for preventing fluid from flowing out of the drainage part 4-3 when being closed, a floating body 4-34 is also arranged in the drainage part 4-3, the valve clack of the second check valve 4-33 is connected with the floating body 4-34 through a traction piece 4-35, when the floating body 4-34 is positioned at the uppermost end of the drainage part 4-3, the floating body 4-34 is generally contacted with and blocked by the exhaust cover 4-31, the float 4-34 opens the second check valve 4-33 by means of the pulling element 4-35, i.e. the length of the pulling element 4-35 plus the length of the float 4-34 is smaller than the distance of the second check valve 4-33 to the venting cover 4-31.

The working principle of the device is as follows: after the aerator 2 is opened, the gas with higher pressure intensity enters the aerator pipe 1 and simultaneously discharges the accumulated water out of the aerator pipe 1 through the first check valve 3, the first exhaust holes 1-1 start to discharge gas one by one to start working, generally, the first exhaust holes 1-1 which are 200m away from the aerator will foam after about 10 minutes, the water is pressed out from the aerator pipe and enters the connecting pipe 4-1, the connecting part 4-2 and the water discharging part 4-3 and almost all is discharged from the second check valve 4-33, the water in the aerator pipe 1 is reduced, the gas gradually enters the connecting pipe 4-1, the connecting part 4-2 and the water discharging part 4-3, the gas flows upwards after entering the water discharging part 4-3 but the second exhaust holes 4-32 are smaller (preferably 2mm-4mm, or smaller as required), the gas cannot be immediately overflowed, the gas gradually increases in the water discharge part 4-3 to gradually lower the floating body 4-34, when the water level drops to a proper position, the second check valve 4-33 is completely closed, the water is not discharged any more, so that the gas directly flows out of the water discharge part 4-3 after the water is emptied, since the aeration device is started up once a day basically and is started up or is started up at intervals of several hours, the gas in the water discharge part 4-3 is gradually discharged through the second vent hole 4-32 to gradually raise the water level in the water discharge part 4-3, and finally the floating body 4-34 pulls the second check valve 4-33 to open to prepare for the next startup.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
