Description

Technical Field

[0001] This utility model relates to the field of sewage discharge equipment technology, and in particular to a sewage discharge device for a cementing laboratory. Background Technology

[0002] In cementing experiments, cement is the most widely used basic material. During a series of performance tests on cement slurry, including its rheological properties, water loss properties, thickening properties, and strength, while the remaining cement slurry or cement stone is usually discarded after the experiment, the wastewater generated from cleaning the experimental equipment presents numerous challenges. Currently, the industry standard practice is to directly discharge the wastewater from the cementing laboratory into outdoor settling tanks. However, this traditional method has many drawbacks.

[0003] Firstly, regarding manual cleaning, after a period of use, a large amount of sediment accumulates at the bottom of the sedimentation tank, requiring manual excavation and cleaning. This not only consumes a lot of manpower and increases labor costs, but also involves a harsh working environment and extremely high labor intensity. Secondly, from an environmental perspective, the water discharged directly after sedimentation still contains a large amount of solid matter. If this solid matter enters the environment directly, it will damage the soil structure, affect soil permeability and fertility, and consequently affect vegetation growth. In terms of water bodies, it will cause turbidity, affecting the living environment of aquatic organisms and disrupting the ecological balance. Furthermore, when the laboratory needs to be moved due to business adjustments, site changes, or other reasons, outdoor sedimentation tanks, due to their fixed nature, often can only be disposed of by landfill. This not only wastes the initial investment in constructing the sedimentation tank, but the landfill process may also incur additional costs, failing to achieve effective resource reuse and not meeting the requirements of sustainable development.

[0021] like Figure 1 The diagram illustrates a preferred embodiment of a cementing laboratory wastewater discharge device, comprising: a collection bag (not shown), a first settling tank 1, a second settling tank 2, and a third settling tank 3.

Rollers are provided at the lower ends of the first settling tank 1, the second settling tank 2, and the third settling tank 3. Collection bags are installed inside each of the three settling tanks, which can be used to collect cement and other sediments produced after the wastewater has settled. Furthermore, when it is necessary to clean the sediments, only the collection bags need to be removed, thereby reducing the need for manual cleaning of sediments in the settling tanks.

[0022] Furthermore, as a preferred embodiment, the roller is preferably configured as a roller with a braking function so as to maintain stability when the first sedimentation tank 1, the second sedimentation tank 2 and the third sedimentation tank 3 are in operation.

[0023] Furthermore, as a preferred embodiment, one side of the first sedimentation tank 1 is connected to an external drainage pipeline.

[0026] Furthermore, as a preferred embodiment, the other side of the third settling tank 3 is connected to an external sewage discharge pipe. Furthermore, a filter element is installed inside the sewage discharge pipe to facilitate the filtration of the water within the pipe.

[0027] Furthermore, as a preferred embodiment, the inner walls of the first sedimentation tank 1, the second sedimentation tank 2, and the third sedimentation tank 3 are all provided with internal threads. The drain pipe and the first connecting water pipe 4 are both threaded to the first sedimentation tank 1, the first connecting water pipe 4 and the second connecting water pipe 5 are both threaded to the second sedimentation tank 2, and the second connecting water pipe 5 and the sewage discharge pipe are both threaded to the third sedimentation tank 3.

[0028] Furthermore, as a preferred embodiment, a first filter screen 6 is provided on the inner wall of the first sedimentation tank 1, and the first filter screen 6 is in contact with the first connecting water pipe 4.

[0029] Furthermore, as a preferred embodiment, a second filter screen 7 is provided on the inner wall of the second sedimentation tank 2, and the second filter screen 7 is in contact with the second connecting water pipe 5.

[0030] Furthermore, as a preferred embodiment, a third filter screen 8 is provided on the inner wall of the third sedimentation tank 3, and the third filter screen 8 is in contact with the sewage discharge pipe.

[0031] Furthermore, as a preferred embodiment, the upper ends of the first settling tank 1, the second settling tank 2, and the third settling tank 3 are all provided with top covers. The top covers are used to prevent dust from falling into the first settling tank 1, the second settling tank 2, or the third settling tank 3 and affecting the settling effect.

[0032] Furthermore, as a preferred embodiment, see [link to previous document]. Figure 1 As shown, the size of the first sedimentation tank 1 is larger than the size of the second sedimentation tank 2, and the size of the second sedimentation tank 2 is larger than the size of the third sedimentation tank 3.

[0033] Furthermore, as a preferred embodiment, it also includes: a guide plate 9 and a baffle 10. The guide plate 9 is disposed inside the first sedimentation tank 1, and the height of the guide plate 9 is lower than the height of the sewer pipe. A baffle 10 is also disposed on the inner wall of the first sedimentation tank 1, near the other side of the first sedimentation tank 1. The baffle 10 is arranged vertically, and the guide plate 9 is arranged horizontally. Furthermore, the guide plate 9 is used to guide the sewage flowing in from the sewer pipe, allowing it to enter the first sedimentation tank 1 smoothly, avoiding the impact of water flow on the sedimentation effect. The baffle 10 is used to create a specific flow path for the sewage within the first sedimentation tank 1, thereby improving sedimentation efficiency.

[0034] Furthermore, as a preferred embodiment, see [link to previous document]. Figure 1 As shown, the second sedimentation tank 2 and the third sedimentation tank 3 are equipped with guide plates 9. The height of the guide plate 9 in the second sedimentation tank 2 is lower than the height of the first connecting water pipe 4, and the height of the guide plate 9 in the third sedimentation tank 3 is lower than the height of the second connecting water pipe 5. Baffles 10 are provided on the inner walls of both the second sedimentation tank 2 and the third sedimentation tank 3. The baffles 10 in the second sedimentation tank 2 are closer to the other side of the second sedimentation tank 2, and the baffles 10 in the third sedimentation tank 3 are closer to the other side of the third sedimentation tank 3.

[0035] The working principle of this utility model is as follows: External sewage enters the first sedimentation tank 1 through the drain pipe, flows along the guide plate 9 and falls to the side of the baffle 10 closest to the first filter screen 6. As the sewage inflow into the first sedimentation tank 1 increases, the sewage on the side of the baffle 10 closest to the first filter screen 6 gradually overflows to the side of the baffle 10 furthest from the first filter screen 6. As the sewage inflow into the first sedimentation tank 1 continues to increase, the settled sewage can pass through the first filter screen 6 into the first connecting water pipe 4, and then through the first connecting water pipe 4 into the second sedimentation tank 2. After entering the second sedimentation tank 2, the sewage flows along the guide plate 9 and falls to the side of the baffle 10 closest to the second filter screen 7. As the sewage inflow into the second sedimentation tank 2 increases, the sewage on the side of the baffle 10 furthest from the first filter screen 6 gradually overflows to the side of the baffle 10 furthest from the first filter screen 6. The sewage on one side of the second filter screen 7 will gradually overflow to the side of the baffle 10 away from the second filter screen 7. As the sewage inflow into the second sedimentation tank 2 continues to increase, the settled sewage can enter the second connecting water pipe 5 through the second filter screen 7, and then enter the third sedimentation tank 3 through the second connecting water pipe 5. After entering the third sedimentation tank 3, the sewage will flow along the guide plate 9 and fall to the side of the baffle 10 near the third filter screen 8. As the sewage inflow into the third sedimentation tank 3 increases, the sewage on the side of the baffle 10 near the third filter screen 8 will gradually overflow to the side of the baffle 10 away from the third filter screen 8. As the sewage inflow into the third sedimentation tank 3 continues to increase, the settled sewage can enter the sewage discharge pipe through the third filter screen 8, and then be discharged through the sewage discharge pipe.
