Description

Technical Field

[0001] The utility model relates to the field of water supply and drainage, in particular to an automatic flushing device for inclined plates / tubes of a sedimentation tank. Background Art

[0002] At present, the sedimentation process in the conventional water treatment process is one of the key steps that determine the process operation effect. The efficient sedimentation process can not only significantly reduce the turbidity of the effluent from the sedimentation tank, reduce the filtration pressure of the subsequent filter tank, and prevent the occurrence of filter tank penetration accidents, but also reduce the use of flocculants at the front end of the sedimentation tank and reduce water treatment costs.

[0003] The high-efficiency sedimentation device designed based on the principle of "shallow sedimentation" can significantly improve the sedimentation efficiency of the sedimentation tank. This type of device installs inclined plates / tubes in the sedimentation tank to change the flow of the sedimentation tank from a single layer to multiple layers, reducing the sedimentation distance of the flocs and significantly improving the sedimentation efficiency. The sedimentation device equipped with inclined plates / tubes overcomes the problems of large floor space and long sedimentation time of traditional sedimentation tanks, making the water treatment device develop in the direction of miniaturization. At present, the most commonly used is the horizontal split-flow inclined plate / tube sedimentation device, but this device still has some problems in the actual water treatment process. For example, the flocs are prone to accumulation on the inclined plate / tube during the sedimentation process. If the device is not cleaned and maintained in time, it is easy to cause the inclined plate / tube to be blocked, which reduces the sedimentation efficiency of the sedimentation tank and leads to poor water quality of the effluent.

[0004] At present, the cleaning and maintenance of the inclined plate / tube is mainly done manually. During the flushing operation, the water level in the sedimentation tank is first lowered to the bottom of the inclined plate / tube or the inclined plate / tube is lifted out of the sedimentation tank, and then the inclined plate surface is flushed with a water gun. This is not only time-consuming and labor-intensive, but also has certain risks during the operation. At the same time, due to the compact installation of the inclined plate / tube, manual flushing is difficult to effectively clean the inside of the inclined plate / tube and the wing plate installed under the inclined plate, and the cleaning efficiency is low and the cleaning effect is difficult to be satisfactory. Although there are currently automated devices for flushing the inclined plate / tube of the sedimentation tank, external pipes are required during the flushing operation, which is inconvenient to implement and still requires a large amount of labor.

[0042] The utility model integrates the pump 203 and the flushing carriage 2 together. The pump 203 moves with the flushing carriage 2. At the same time, the pump 203 is connected to the sedimentation tank 1 to provide flushing water to the inclined plate / pipe 101, eliminating the cumbersome external pipes.

[0044] Among them, at least one group of inclined plates / tubes 101 can be one group, two groups, or more groups. More than two groups means that they are all inclined plates, or all inclined tubes, or a combination of inclined plates and inclined tubes.

The pump shaft of the long-axis pump 203 passes from the channel 102 to the sedimentation tank 1 so that the water suction port of the long-axis pump 203 is located in the water to provide water for flushing.

[0048] The long-axis pump 203 is a centrifugal pump, which has a simple structure, is easy to operate and maintain, can deliver the medium continuously and smoothly, and is easy to automate and remotely control.

[0049] By installing the long-axis pump 203 on the flushing carriage 2 and positioning the flushing carriage 2 above the channel 102, the pump shaft of the long-axis pump 203 directly passes through the sedimentation tank 1 from the channel 102, and provides flushing water to the inclined plate / pipe 101 at any time during the reciprocating motion of the flushing carriage 2.

The track 3 is fixed on the lower channel steel 215, and a second cable placement plate 216 is welded on the outer side of one of the lower channel steels 215. The second cable placement plate 216 is on the same side as the first cable placement plate 208. The steel drag chain 209 is placed on the first cable placement plate 208 and the second cable placement plate 216. The steel drag chain 209 has built-in cables required for the flushing device, including flushing vehicle cables, long-axis pump cables, etc. The first cable placement plate 208 and the second cable placement plate 216 are long plates, placed horizontally, and made of steel, such as S30408 ​​flat steel. The sizes of the first cable placement plate 208 and the second cable placement plate 216 can be designed according to actual requirements. By integrating the device cables into the steel drag chain, the clutter of the installation lines is avoided, and the power safety of the device can be improved.

[0053] Specifically, Figure 4As shown, the flushing vehicle 2 includes a driving mechanism and a transmission mechanism, wherein the driving mechanism is a motor 202, and the transmission mechanism includes an axle 210, a bearing 211, a clamp 212 and a pulley 213, wherein the bearing 211 is installed at both ends of the axle 210, the bearing 211 is fixed with a clamp 212, and is connected to the lower end of the upper channel steel 207 by a bolt 214, the pulley 213 is connected to the axle 210 by the bearing 211, the pulley 213 is placed on the track 213, the motor 202 is installed on the side of the platform 201, and the motor 202 drives the pulley 213 to rotate.

[0054] Specifically, the pump 2031 of the long-axis pump 203 is fixed on the platform 201, and the pump shaft 2032 extends into the sedimentation tank 1 through the hole reserved on the flushing carriage 2. The water suction port is arranged on the side or bottom of the lower section of the pump shaft 2032, and when the flushing water is transported, the liquid level at the bottom of the sedimentation tank is ensured to be higher than the water suction port of the long-axis pump 203. The length of the pump shaft can be designed according to the height of the sedimentation tank.

[0055] Specifically, the width of the channel 102 is greater than the diameter of the pump shaft 2032 of the long-axis pump 303 .

[0056] As some optional embodiments, the flushing device includes a flushing pipeline, which includes a plurality of vertical flushing pipelines 204 and horizontal flushing pipelines 205. The vertical flushing pipelines 204 are located in the channel 102 to flush the side surfaces of the inclined plates / tubes on both sides of the channel 102, and the horizontal flushing pipelines 205 flush the top surfaces of the inclined plates / tubes on both sides of the channel 102 respectively.

[0057] The automatic flushing device proposed in the utility model has a vertical flushing pipeline 204 and a horizontal flushing pipeline 205. During the flushing operation, it is not necessary to lift the inclined plate / tube 101 out of the sedimentation tank, and it can go deep into the inclined plate / tube 101, and can effectively clean the inclined plate / tube 101 and the wing plate below the inclined plate which are difficult to be flushed by manual operation. At the same time, during the flushing process, it acts on the inclined plate / tube 101 from both the top and side directions, which not only has a good flushing ability for the accumulated large flocs and sludge, but also has a good shear force for the stubborn sludge adhered to the inclined plate / tube 101, which can improve the cleaning effect of the inclined plate / tube 101. It is also possible to flush two groups of inclined plates / tubes 101 at the same time, and the flushing efficiency is high.

[0058] As some optional embodiments, the flushing pipelines are respectively arranged at the front end and the rear end of the flushing carriage 2 , and the front end and the rear end of the flushing carriage 2 are consistent with the running direction of the flushing carriage 2 .

[0059] Specifically, Figure 2As shown, a group of flushing pipelines are respectively provided at the front end and the rear end of the flushing vehicle 2 , and each group of flushing pipelines includes a vertical flushing pipeline 204 and two horizontal flushing pipelines 205 .

[0060] The flushing device provided by the utility model has vertical flushing pipelines 204 and horizontal flushing pipelines 205 at the front and rear ends of the flushing carriage 2, which can repeatedly flush the inclined plate / pipe 101 in a short time, greatly improving the cleaning efficiency. In addition, the vertical flushing pipeline 204 is arranged at the front and rear ends of the flushing carriage 2, rather than at the left and right ends, so as to avoid the situation where the passage is too narrow to be installed.

[0061] As some optional embodiments, the horizontal flushing pipeline is 4 to 7 cm higher than the inclined plate / pipe.

[0062] Specifically, the length of the vertical flushing pipeline 204 is not less than the height of the inclined plate / pipe 101, and the horizontal flushing pipeline 205 is 5 cm higher than the inclined plate / pipe.

[0063] As some optional embodiments, the pump 203 is connected to a water pipe, the vertical flushing pipeline 204 is connected to the water pipe, and the horizontal flushing pipeline 205 is connected to the vertical flushing pipeline 204 with a 45° elbow arc.

[0064] Specifically, Figure 2 As shown, the outlet of the long-axis pump 203 is connected to a water main 217, and the water main 217 is connected to two water delivery branches 218 symmetrically distributed along the water main 217. Each of the water delivery branches 218 is provided with a pipeline valve 219 for controlling the opening and closing of the pipeline. The pipeline valve 219 can be a manual valve or an electric valve. Each water delivery branch 218 is connected to a set of flushing pipelines, namely a vertical flushing pipeline 204 and two horizontal flushing pipelines 205. The vertical flushing pipeline 204 is connected to the end of the water delivery branch 218, and the horizontal flushing pipeline 205 is connected to the vertical flushing pipeline 204 with a 45° elbow 220 arc, which can improve the hydraulic conditions in the pipelines in both directions, reduce hydraulic losses, and better distribute the spatial flushing water volume. The two horizontal flushing pipelines 205 are symmetrically arranged along the vertical flushing pipeline 204, and the vertical flushing pipeline 204 is located on the center line of the channel 102, which can ensure the stability of the flushing vehicle 2.

[0065] As some optional embodiments, the vertical flushing pipeline 204 and the horizontal flushing pipeline 205 are both installed with two sets of quick-install connectors 221, and a pipeline valve 222 is installed between the two sets of quick-install connectors 221. Blind plates 223 are detachably installed at the ends of the vertical flushing pipeline 204 and the horizontal flushing pipeline 205.

[0066] Specifically, Figure 5As shown, the quick-install joint on the vertical flushing pipeline 204 is close to the connection between the horizontal flushing pipeline 205 and the vertical flushing pipeline 204 and is located below the connection. The quick-install joint on the horizontal flushing pipeline 205 is close to the connection between the horizontal flushing pipeline 205 and the vertical flushing pipeline 204. Installing the quick-install joint 221 is conducive to the disassembly and installation of longer pipelines, and is conducive to the maintenance and replacement of pipeline fittings. The two groups of horizontal flushing pipelines are conducive to the installation, adjustment and disassembly of each horizontal flushing pipeline 205. The two groups of vertical flushing pipelines are conducive to the connection and disassembly work between the upper part of the vertical flushing pipeline 204 and the water supply branch 218, and the quick-install joint at the lower part of the vertical flushing pipeline 204 is connected to the pipeline valve 222, which is conducive to the implementation of the vertical pipe closing and only opening the horizontal pipe operation mode. The pipeline valves 222 are respectively set to control the opening and closing of the vertical flushing pipeline 204 and the horizontal flushing pipeline 205 respectively. The pipeline valve 222 can be a manual valve or an electric valve.

[0067] Specifically, Figure 3 and 6 As shown, blind plates 223 are detachably installed at the ends of the vertical flushing pipeline 204 and the horizontal flushing pipeline 205 to solve the problem of sludge blockage that may occur in the pipelines. After the blind plates 223 are removed, the sludge in the pipelines is flushed with water.

Laser drilling directly on the flushing pipeline as a flushing hole is convenient for production and saves costs. The truncated cone shape that gradually narrows from the inside to the outside is conducive to ensuring the intensity and distance of the jet flushing after the pipeline is filled with water. The appropriate solid angle allows the flushing water to form a full stream of water, which has a good flushing effect on the inclined plate and sludge, and avoids the water out of the flushing hole presenting a diffuse posture and reducing the flushing effect.

[0070] As some optional embodiments, the water outlet angle of the vertical flushing pipeline 204 is perpendicular to the inclined plate / tube 101 , and the water outlet angle of the horizontal flushing pipeline 205 is 53° to 80°, which is the same as the inclination direction of the inclined plate / tube 101 .

[0071] Specifically, the water outlet angle β of the horizontal flushing pipeline 205 is 53° to 80°, which is the same as the inclination direction of the inclined plate / tube 101, see Figure 8 β is preferably 53.58° to 79.39°, most preferably 60°, see Fig. 9A, 9B, 9C. Taking the inclined plate as an example, the inclined plate is composed of a bottom plate 1011, a wing plate 1012 and a rib plate 1013. The wing plate 1012 is arranged at an angle on the front of the bottom plate 1011, and the rib plate 1013 is arranged on the back of the bottom plate 1011. The wing plate 1012 of the front inclined plate is plugged into the rib plate 1013 of the rear inclined plate. The water outlet angle of 53.58° of the horizontal flushing pipeline 205 is the angle between the intersection line of the water flow and the end of the front inclined plate wing plate 1012 and the horizontal line, see Fig. 9 A, the water outlet angle 79.39° is the angle between the intersection line of the water flow and the end of the rear inclined plate wing 1012 and the horizontal line, see Fig. 9 C.

[0072] Specifically, the vertical flushing pipeline 204 is symmetrically opened along the pipeline radial direction, and the water outlet angle is perpendicular to the inclined plate / tube 101. The horizontal flushing pipeline 205 is opened on one side, and the water outlet angle β is the same as the inclination angle of the inclined plate / tube 101, which is 60°.

[0073] Specifically, the spacing between the two flushing holes 206 on the same side of the vertical flushing pipeline 204 is smaller than the vertical distance between the upper and lower adjacent inclined plates / tubes 101, and the effective flushing length of each horizontal flushing pipeline 205 is not less than the width of a single group of inclined plates / tubes 101.

[0074] As some optional embodiments, the moving speed of the flushing vehicle 2 is 0.7-1.1 m / min, and the flushing time between the two inclined plates / tubes 101 during movement is maintained at 5-8 s.

[0075] Specifically, the moving speed of the flushing vehicle 2 is 0.7 m / min, and the flushing time between the two inclined plates / tubes 101 during movement is maintained at 8 s.

[0076] Specifically, limiters 301 are provided at both ends of the track 3 to prevent the flushing vehicle 2 from derailing.

[0077] Specifically, the flushing device is provided with a control system, which can be located in a position independent of the flushing carriage 2, such as a backstage control room, and can control the start, shut down and speed of the flushing carriage 2, the start and shut of the pump, and the flow rate of the flushing pipeline.

[0078] There are two methods for flushing the inclined plate / tube 101 using the automatic flushing device of the above-mentioned sedimentation tank inclined plate / tube. One method is to empty the sedimentation tank 1 and only use the pressure water from the flushing hole 206 to flush the inclined plate / tube 101. The other method is to have water in the sedimentation tank 1 and use the pressure water from the flushing hole 206 to drive the water in the tank to flush the inclined plate / tube 101.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to replace some of the technical features therein with equivalents.
