Description

Technical Field

[0001] The utility model relates to water quality monitoring technology, in particular to a flow-through tank for water quality monitoring with hydraulic self-cleaning and constant water storage. Background Technique

[0002] With the increasingly strict environmental protection regulations, the requirements for drainage monitoring are also getting higher and higher. In order to combat illegal discharges, many industrial parks and municipal sewage treatment departments have begun to increase the monitoring equipment for drainage pipelines to ensure that the sewage discharged in the sewage pipelines meets the inlet standards of downstream sewage treatment plants.

[0003] Since the sewage pipelines are usually long, with large flow fluctuations and a wide monitoring range, it is impossible to conduct conventional online monitoring. Therefore, most of them adopt the characteristic pollutant indicators that are easy to monitor in the pipelines, such as salt content, turbidity, temperature and other indicators that can be monitored in real time. These indicators usually adopt monitoring technologies such as the electrode method, the ion membrane method and the optical method, or a combination of these technologies.

[0004] However, these monitoring probes mentioned above have a common problem: due to the instability of the flow rate in the sewage pipe, the liquid level fluctuates, and the probe may be exposed to the air, which will not only damage the diaphragm and the photosensitive element, but also lead to a decrease in monitoring accuracy. The traditional solution is to build a water retaining wall to raise the water level, but this will reduce the drainage head. At the same time, the sediment in the sewage will soon cover the probe, and manual cleaning needs to be carried out regularly, consuming a large amount of manpower and material resources. Content of the Utility Model

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 4 , when the present utility model is specifically implemented, the flow-through tank for water quality monitoring with self-cleaning and constant water storage includes a housing 1. The housing 1 can be made of materials such as commercial concrete, PP, fiberglass, stainless steel, and carbon steel that are easily available locally. An inlet 2 is provided on one side of the top of the housing 1, and an outlet 3 is provided on the other side of the top of the housing 1. A base 4 adapted to it is inserted at the bottom of the housing 1. The base 4 is slidably sealed with the housing 1. A self-cleaning flow channel 5 is provided on the base 4. The base 4, especially the self-cleaning flow channel 5 at the top, can be made of materials with relatively low surface roughness such as PP, fiberglass, and stainless steel. The curve in the self-cleaning flow channel 5 is analyzed in a fluid analysis software according to the local sewage density and viscosity index or existing data, and is respectively fitted with the brachistochrone curve and the shortest curve. Under the influence of the same gravity, the sewage first accelerates to the fastest speed, and then carries the bottom sediment through the shortest rising curve and accelerates beyond its sedimentation speed to achieve the self-cleaning function. In case of a large sediment content or high sewage viscosity, the elevation of the outlet 3 can be lowered to be slightly lower than that of the inlet 2 to facilitate sand discharge. The inlet end of the self-cleaning flow channel 5 is flush with the inlet 2, and the outlet end of the self-cleaning flow channel 5 is higher than the outlet 3. A monitoring probe 6 penetrates through the top of the housing 1, and the head of the monitoring probe 6 is inserted into the self-cleaning flow channel 5.

[0024] By arranging a curved self-cleaning flow channel 5 between the inlet 2 and the outlet 3, the head of the monitoring probe 6 can always be located in the submerged water in the self-cleaning flow channel 5 while the water flow can wash away the sediment, avoiding the exposure of the head of the monitoring probe 6 and playing a protective role. It uses the drainage flow rate for self-cleaning without additional power, and at the same time can ensure that the probe continuously and stably remains below the water surface for accurate monitoring. This design not only improves the monitoring efficiency but also greatly reduces the maintenance cost.

[0025] The bottom height of the outlet 3 is lower than the bottom height of the inlet 2, so as to facilitate the smooth flow even when the height of the outlet end of the self-cleaning flow channel 5 decreases. An outlet pipe 7 is fixedly connected to the outside of the outlet 3, and an inlet pipe 8 is fixedly connected to the outside of the inlet 2. There are various types of self-cleaning flow channels 5.

[0026] The base 4 is hollow, and a first fixed flange 9 is fixedly connected to the bottom of the base 4. A second fixed flange 10 is fixedly connected to the bottom opening of the outer housing 1. Fixing bolts 11 are uniformly penetrated through the second fixed flange 10 and the first fixed flange 9 together. Circular holes for the fixing bolts 11 to penetrate are provided on both the second fixed flange 10 and the first fixed flange 9. After the fixing bolts 11 penetrate through the second fixed flange 10 and the first fixed flange 9, nuts are threadedly connected.

[0027] The base 4 is assembled and installed with the outer housing 1 through the cooperation of the first fixed flange 9 and the second fixed flange 10 and the fixing bolts 11, so that the base 4 can be replaced, and thus the self-cleaning chute 5 with different curves can be conveniently replaced according to different sewage conditions, improving the adaptability of the device.

[0028] The monitoring probe 6 is fixedly connected inside the outer sleeve 12. The outer sleeve 12 plays an effect of isolating and protecting the monitoring probe 6. A wiring hole is provided at the top of the outer sleeve 12. The outer sleeve 12 itself can dissipate heat through heat conduction. A guiding tube 13 adapted to it is movably sleeved on the outside of the outer sleeve 12, and the guiding tube 13 fixedly penetrates through the top of the outer housing 1.

[0029] A plurality of sealing rings 14 are equidistantly embedded on the inner side of the guiding tube 13, and the sealing rings 14 are attached to the outer wall of the outer sleeve 12.

[0030] A notch 15 is provided at the top of the guiding tube 13. An extrusion block 16 adapted to it is provided in the notch 15. A locking bolt 17 is threadedly connected to the guiding tube 13 corresponding to the extrusion block 16. A nut for the locking bolt 17 to be threadedly connected is fixedly connected to the guiding tube 13. A perforation is provided on the guiding tube 13 corresponding to the nut. The threaded end of the locking bolt 17 is rotatably connected to one side of the extrusion block 16. The extrusion block 16 fits and slides on the inner wall of the notch 15. Scale lines 18 are uniformly provided on the outer wall of the outer sleeve 12.

[0031] The monitoring probe 6 is inserted into the outer housing 1 through the cooperation of the outer sleeve 12 and the guiding tube 13. Among them, it is squeezed and fixed through the cooperation of the locking bolt 17 and the extrusion block 16, and the insertion depth of the monitoring probe 6 is adjusted in cooperation with the scale lines 18, so as to be adapted to different situations for use.

[0032] The working principle of the present utility model is:

[0033] When in use, water flow enters the water inlet 2 through the water inlet pipe 8, flows through the self-cleaning chute 5 on the base 4 to the water outlet 3, and finally is discharged through the water outlet pipe 7. At this time, the water flow can wash away the sediment in the self-cleaning chute 5. At the same time, when the flow rate is unstable, water is always stored at the bottom of the self-cleaning chute 5 to submerge the head of the monitoring probe 6, and the water flow is continuously monitored by the monitoring probe 6 when passing through the self-cleaning chute 5.

[0034] In use, according to the local sewage density and viscosity index, analyze in fluid analysis software or adopt existing data, and fit them with the brachistochrone curve and the shortest curve respectively. Under the influence of the same gravity, the sewage first accelerates to the fastest speed, and then carries the bottom sediment through the shortest rising curve and accelerates it beyond its sedimentation speed to obtain the required self-cleaning chute 5 curve. At this time, insert the base 4 into the bottom of the outer casing 1, and fix the first fixing flange 9 and the second fixing flange 10 through the fixing bolts 11 to achieve an adaptive combination.

[0035] Insert the outer sleeve 12 downward through the guide tube 13, control the insertion depth in cooperation with the scale line 18, and further fix the outer sleeve 12 by rotating the locking bolt 17 and squeezing the outer sleeve 12 through the squeezing block 16, so as to realize the control of the insertion depth of the monitoring probe 6.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
