Movable pumping and storage sedimentation basin

Abstract

This utility model provides a movable pumping and storing sedimentation tank, including a sedimentation tank shell and a first partition plate and a second partition plate disposed within the sedimentation tank shell. Both the first and second partition plates are detachably connected to the sedimentation tank shell, dividing the sedimentation tank shell into a first chamber, a second chamber, and a third chamber. Each of the first, second, and third chambers is equipped with a piston-type pump. The detachable connection of the first and second partition plates to the sedimentation tank shell allows for flexible adjustment of the chamber combination according to the characteristics of the wastewater, discharge requirements, and treatment objectives. When only physical treatment is required, the first and second partition plates can be removed to merge the chambers, retaining only the first chamber. When any combination of physical, chemical, or biological methods is required for wastewater treatment, the first and second partition plates can be quickly installed to form the corresponding chambers, adapting to changes in different operating conditions.

Description

Technical Field

[0001] This utility model relates to the field of sedimentation tank technology, specifically to a mobile pumpable water storage sedimentation tank. Background Technology

[0002] Construction wastewater and sludge at construction sites must be disposed of using a three-stage sedimentation and discharge system. With the rapid development of construction projects and the increasing speed of construction, the availability of temporary land during construction is decreasing. Against this backdrop, the location of sedimentation tanks during construction presents a construction challenge, as it is difficult to determine and requires frequent relocation. To address this problem, Chinese patent document CN206837562U discloses a mobile prefabricated multi-stage sedimentation tank.

[0003] However, in actual use, it has been found that in construction site wastewater treatment, the three-stage sedimentation tanks (physical, chemical, and biological chambers) are not always fully utilized. Depending on the wastewater's characteristics, discharge requirements, and treatment objectives, certain treatment stages can be selectively skipped, as illustrated below:

[0004] Examples of using only physical chambers: In some construction sites where earthwork is the primary activity, the wastewater generated during light rain is mainly composed of silt and sand, containing almost no chemical pollutants or biodegradable organic matter. In such cases, using only a physical chamber is sufficient to meet the treatment needs.

[0005] An example of using physical and chemical chambers: During steel structure welding operations at a construction site, oily wastewater and sewage containing small amounts of welding fumes and other pollutants are generated. This type of wastewater contains substances such as grease that are difficult to remove completely by physical methods, and the grease can affect the activity of microorganisms in biological treatment, making it unsuitable for direct entry into the biological chamber. Therefore, the physical chamber is activated first to remove larger impurities through a screen, followed by sedimentation in a settling tank to settle some of the silt. Subsequently, appropriate amounts of demulsifiers and flocculants are added to the chemical chamber to cause the grease to form flocs and precipitate, further reducing the concentration of pollutants in the wastewater. The treated wastewater meets relevant discharge standards and requires no further biological treatment. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to propose a mobile pumping and water storage sedimentation tank to solve the problems mentioned in the background section above.

[0007] This utility model is achieved through the following technical solution:

[0008] A movable pumpable sedimentation tank includes a sedimentation tank shell and a first partition plate and a second partition plate disposed in the sedimentation tank shell. The first partition plate and the second partition plate are detachably connected to the sedimentation tank. The first partition plate and the second partition plate are used to divide the sedimentation tank shell into a first chamber, a second chamber and a third chamber. A piston pump is provided in each of the first chamber, the second chamber and the third chamber. The pumping hole of the piston pump penetrates downward through the sedimentation tank shell.

[0009] Furthermore, the bottom of the sedimentation tank shell is provided with support legs, the bottom of the support legs is provided with casters, and the support legs are telescopic structures.

[0010] Furthermore, sealing rings are glued to the three surfaces of the first and second partition plates that contact the sedimentation tank shell.

[0011] Furthermore, each of the two inner walls of the sedimentation tank shell is provided with two spaced-apart first guide strips, and the first partition plate is disposed between the first guide strips; each of the two inner walls of the sedimentation tank shell is provided with two spaced-apart second guide strips, and the second partition plate is disposed between the second guide strips.

[0012] Furthermore, the first partition plate is provided with a first overflow port, the second partition plate is provided with a second overflow port, the height of the first overflow port is higher than that of the second overflow port, the first chamber is provided with a liquid inlet communicating with the outside, and the third chamber is provided with a liquid outlet communicating with the outside.

[0013] Furthermore, the upper end of the first chamber is provided with a rotatable first cover plate, the upper end of the second chamber is provided with a rotatable second cover plate, the upper end of the third chamber is provided with a rotatable third cover plate, and the bottom of the sedimentation tank shell is provided with a cleaning port.

[0014] The beneficial effects of this utility model are as follows: A movable pumping and storing sedimentation tank includes a sedimentation tank shell, and further includes a first partition plate and a second partition plate disposed within the sedimentation tank shell. Both the first and second partition plates are detachably connected to the sedimentation tank. The first and second partition plates divide the sedimentation tank shell into a first chamber, a second chamber, and a third chamber. Each of the first, second, and third chambers is equipped with a piston-type water pump, the pump's suction port penetrating downwards through the sedimentation tank shell. The detachable connection of the first and second partition plates to the sedimentation tank shell allows for flexible adjustment of the chamber combination according to the wastewater quality characteristics, discharge requirements, and treatment objectives. When only physical treatment is required, the first and second partition plates can be removed to merge the chambers, retaining only the first chamber. When any combination of physical, chemical, or biological methods is required for wastewater treatment, the first and second partition plates can be quickly installed to form the corresponding chambers, adapting to changes in different operating conditions.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is intended to aid in understanding this utility model, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Reference Figures 1 to 4 As shown, a movable pumping and water storage sedimentation tank includes a sedimentation tank shell 1, and a first partition plate 2 and a second partition plate 3 disposed in the sedimentation tank shell 1. The first partition plate 2 and the second partition plate 3 are both detachably connected to the sedimentation tank. The first partition plate 2 and the second partition plate 3 are used to divide the sedimentation tank shell 1 into a first chamber 11, a second chamber 12 and a third chamber 13. A piston pump 4 is provided in each of the first chamber 11, the second chamber 12 and the third chamber 13. The pumping hole 41 of the piston pump 4 penetrates downward through the sedimentation tank shell 1.

[0023] The first partition plate 2 and the second partition plate 3 are detachably connected to the sedimentation tank shell 1, allowing for flexible adjustment of the chamber combination according to the characteristics of the wastewater, discharge requirements, and treatment objectives. When only physical treatment is required, the first partition plate 2 and the second partition plate 3 can be removed to merge the chambers, leaving only the first chamber 11. When any combination of physical, chemical, or biological methods is required for wastewater treatment, the first partition plate 2 and the second partition plate 3 can be quickly installed to form the corresponding chambers, adapting to changes in different operating conditions.

[0024] The first chamber 11 is mainly used as a physical chamber, the second chamber 12 is mainly used as a chemical chamber, and the third chamber 13 is mainly used as a biological chamber.

[0025] When in use, if the user needs to perform physical sedimentation, chemical sedimentation or biological sedimentation, the user can start the piston pump 4 corresponding to the first chamber 11, the second chamber 12 or the third chamber 13 to pump the external sewage into the corresponding first chamber 11, the second chamber 12 or the third chamber 13 for sedimentation.

[0026] The bottom of the sedimentation tank shell 1 is provided with a support leg 5, and the bottom of the support leg 5 is provided with a universal wheel 6. The support leg 5 is a telescopic structure.

[0027] By setting universal wheels 6, the water pumping and sedimentation tank of this utility model can be moved arbitrarily to the area where sewage exists. When the sewage is in a pit, the support legs 5 are retracted so that the pumping hole 41 of the piston pump 4 comes into contact with the sewage, and then the piston pump 4 is driven to pump water.

[0028] The piston pump 4 can be a manual piston pump or an electrically controlled piston pump. The specific structure of the piston pump 4 is existing technology and will not be described in detail here. The telescopic structure of the support leg 5 can be adjusted in height through the cooperation of inner and outer tubes and telescopic spring pins. This part of the structure is existing technology and will not be described in detail here.

[0029] Reference Figure 4 As shown, sealing rings 22 are glued to the three surfaces of the first partition plate 2 and the second partition plate 3 that contact the sedimentation tank shell 1. Grooves are provided on the front, back, and sides of the first partition plate 2 and the second partition plate 3. The sealing rings 22 are then embedded into the grooves and glued in place. The sealing rings 22 abut against the first guide strip 14 or the second guide strip 15 (described below) to prevent the sewage in the first chamber 11, the second chamber 12, and the third chamber 13 from flowing into each other. This is ensured by designing the arrangement of the sealing rings 22.

[0030] The sedimentation tank shell 1 has two spaced-apart first guide strips 14 on each of its two inner walls, with the first partition plate 2 positioned between the first guide strips 14; the sedimentation tank shell 1 also has two spaced-apart second guide strips 15 on each of its two inner walls, with the second partition plate 3 positioned between the second guide strips 15. The first guide strips 14 are used for positioning and guiding the connection between the first partition plate 2 and the sedimentation tank shell 1, and the second guide strips 15 are used for positioning and guiding the connection between the second partition plate 3 and the sedimentation tank shell 1.

[0031] The first partition plate 2 is provided with a first overflow port 21, the second partition plate 3 is provided with a second overflow port 31, the height of the first overflow port 21 is higher than that of the second overflow port 31, the first chamber 11 is provided with a liquid inlet 16 connected to the outside, and the third chamber 13 is provided with a liquid outlet 17 connected to the outside.

[0032] As an extended embodiment, other sludge pumping devices can be connected to the liquid inlet 16. Sludge flows into the first chamber 11 through the liquid inlet 16. After physical sedimentation, the relatively clear water in the middle layer flows into the second chamber 12 through the first overflow outlet 21. After chemical sedimentation in the second chamber 12, it flows into the third chamber 13 through the second overflow outlet 31. After biological sedimentation in the third chamber 13, it is discharged from the pumping and water storage sedimentation tank of this utility model through the liquid outlet 17.

[0033] Furthermore, the upper end of the first chamber 11 is provided with a rotatable first cover plate 71, the upper end of the second chamber 12 is provided with a rotatable second cover plate 72, the upper end of the third chamber 13 is provided with a rotatable third cover plate 73, and the bottom of the sedimentation tank shell 1 is provided with a cleaning port 18.

[0034] The first partition 2 can be easily pulled out or installed by opening the first cover plate 71 and the second cover plate 72, thus avoiding the first partition plate 2. Similarly, the second partition plate 3 can be easily pulled out or installed by opening the second cover plate 72 and the third cover plate 73, thus avoiding the second partition plate 3.

[0035] The second cover plate 72 can be opened, and then chemical agents can be added to the second chamber 12 to cause the dissolved pollutants in the water to form insoluble precipitates, thereby removing them. All of the above precipitates can be discharged through the cleaning port 18.

[0036] The above-mentioned precipitates can be removed by opening the third cover plate 73 and adding biological flocculant to the third chamber 13, which causes microorganisms in the water to metabolize, flocculate, and settle. All of these precipitates can be discharged through the cleaning port 18.

[0037] The liquid inlet 16, liquid outlet 17, and cleaning outlet 18 can be controlled to open or close using existing technologies such as manual or electric gate valves (not shown in the figure), which will not be described in detail here.
