Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically to a sampling sedimentation tank for environmental monitoring. Background Technology

[0002] Environmental monitoring is a fundamental task in environmental protection and is of great significance for maintaining ecological balance and protecting human health. Through environmental monitoring, environmental problems can be identified and resolved in a timely manner, providing a scientific basis for environmental management and decision-making. Regular monitoring of water and other environmental elements will be conducted, which will involve the use of sampling sedimentation tanks.

[0003] When using existing sampling sedimentation tanks, it is generally necessary to wait for a period of time to allow suspended solids to settle fully, based on the characteristics of the wastewater and monitoring requirements, and then use appropriate sampling tools to take samples from the top of the sedimentation tank. As a result, the separation of wastewater and impurity particles is slow and the effect is not good.

[0004] To overcome the above-mentioned defects, the prior art (Chinese patent application number: 201420638030.0, application date: October 29, 2014) discloses a sampling sedimentation tank for environmental monitoring. This sampling sedimentation tank is produced by sedimentation filtration, thereby achieving a high-efficiency filtration effect. At the same time, by setting the feed pipe on the side of the shell and the filter screen, additives can be applied midway, and the additives can be effectively integrated into the sampled material, which is more conducive to detection, convenient to use, and easy to promote.

[0005] While existing technologies can solve the problem of wastewater sedimentation and filtration, and while sedimentation and filtration can remove most suspended solids and particulate matter, their removal effect may not be ideal for some small particles or dissolved substances. Because it is impossible to perform dual filtration and separation and collection of wastewater, the accuracy and reliability of monitoring results may be affected by the residue or uneven distribution of impurity particles when monitoring the separated wastewater and impurity particles. Furthermore, the sampling sedimentation tank is sealed, making it impossible to quickly disassemble the sampling sedimentation tank, which is inconvenient for cleaning or maintenance, and it is also impossible to completely remove the separated impurity particles.

[0006] Therefore, we proposed a sampling sedimentation tank for environmental monitoring that can effectively solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to provide a sampling sedimentation tank for environmental monitoring, in order to solve the problems mentioned in the background art. Currently, when using a sampling sedimentation tank for environmental monitoring on the market, although sedimentation filtration can remove most suspended solids and particulate matter, its removal effect on some small particles or dissolved substances may not be ideal. Since it cannot perform dual filtration separation and collection of sewage, the accuracy and reliability of monitoring results may be affected by the residue or uneven distribution of impurity particles when monitoring the separated sewage and impurity particles. In addition, the sampling sedimentation tank is sealed, making it impossible to quickly disassemble the sampling sedimentation tank, which is inconvenient for cleaning or maintenance, and it is impossible to completely remove the separated impurity particles.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-7 The present invention provides the following technical solution:

[0034] Example 1: To address the issue that while a commercially available environmental monitoring sampling sedimentation tank can remove most suspended solids and particulate matter, its removal efficiency for some fine particles or dissolved substances may be insufficient. Furthermore, because it cannot perform dual filtration and collection of wastewater, subsequent monitoring of the separated wastewater and impurities may be affected by residual or unevenly distributed impurities, impacting the accuracy and reliability of the monitoring results. (See attached...) Figure 1 - Appendix Figure 5 The system includes a sedimentation tank 1, a fixing frame 2 fitted around the sedimentation tank 1, a liquid outlet pipe 3 fixedly connected to the bottom of the sedimentation tank 1, a collection box fixedly installed at the bottom of the liquid outlet pipe 3, and a sealing cover 5 fitted around the top of the sedimentation tank 1; it also includes: a feed pipe 6 fixedly connected to the top of both sides of the sealing cover 5, a servo motor body 8 installed on the top of the sealing cover 5, a rotating rod 9 fixedly installed on the output shaft of the servo motor body 8 through a coupling, and the end of the rotating rod 9 penetrating the sealing cover 5, several stirring blades 10 fitted around the outside of the rotating rod 9, three connecting plates 11 fixedly installed on the inner wall of the sealing cover 5, and a separation sleeve 12 fitted around the bottom outer wall of the connecting plates 11; the separation sleeve 12 and the filter screen 16 are tightly fitted, and the filter screen 16 is a fine filter screen, several water outlet holes 15 are opened inside the separation sleeve 12, and the filter screen 16 is installed at the bottom of the separation sleeve 12.

[0035] Wastewater requiring environmental monitoring is fed into sedimentation tank 1 through feed pipe 6 by staff. An appropriate amount of coagulant is added based on the amount of wastewater added. The servo motor 8 is activated by an external control panel, causing its output shaft to drive several stirring blades 10 connected to rotating rod 9. The stirring blades 10 uniformly stir the wastewater and coagulant, effectively promoting the coagulation of impurities in the wastewater into larger flocs, facilitating subsequent sedimentation and separation. As the wastewater flows and particles settle, the coagulated impurities settle to the bottom of separation sleeve 12 under gravity. Several outlet holes 15 and a filter screen 16 within separation sleeve 12 then perform dual filtration and separation of the wastewater and coagulated particulate impurities, improving wastewater treatment efficiency. The separated wastewater is then collected in a collection tank through outlet pipe 3. This process of separating and collecting wastewater for environmental monitoring in the sampling sedimentation tank facilitates subsequent monitoring of the separated wastewater and impurities.

[0036] Example 2: The sampling sedimentation tank can be quickly disassembled; please refer to the attached document. Figure 1 - Appendix Figure 4 and attached Figure 6 Mounting brackets 19 are fixedly installed on the bottom of both sides of the sealing cover 5. A micro motor body 20 is housed inside the mounting bracket 19, and a gear 21 is fixedly installed on the output shaft of the micro motor body 20 via a coupling. A fixing plate 22 is fixedly installed on the left side of the mounting plate 17. A guide rod 23 passes through the interior of the fixing plate 22, and a baffle 18 is fixedly installed at the rear end of the guide rod 23. A clamping plate 7 is fixedly connected to the bottom of the baffle 18, and several first teeth 4 are provided on the top of the clamping plate 7. The mounting plate 17 is fitted onto the outer wall of the clamping plate 7, and the end of the mounting plate 17 is fixedly connected to the sedimentation tank 1. The gear 21 is meshed with the first teeth 4, the first teeth 4 are fixedly connected to the clamping plate 7, and the clamping plate 7 is movably connected to the mounting plate 17. The baffle 18 is located on the inner wall of the mounting plate 17, and a groove is formed on the inner wall of the mounting plate 17.

[0037] The two micro motor bodies 20 are activated by an external control board, causing the output shaft of the micro motor body 20 to drive the gear 21 to rotate counterclockwise. The gear 21 then meshes with the first tooth 4, causing the first tooth 4 to move the clamping plate 7 outward. During the movement of the clamping plate 7, the guide rod 23 connected to the baffle 18 moves outward within the fixed plate 22. As a result, the clamping plate 7 moves outward from the mounting plate 17 within the groove. The operator manually lifts the sealing cover 5 upward until the sealing cover 5 drives the separation sleeve 12 to remove the sedimentation tank 1. This allows for quick disassembly of the sampling sedimentation tank, facilitating subsequent cleaning, maintenance, and component replacement. This provides a strong guarantee for the long-term stable operation of the sampling sedimentation tank.

[0038] Example 3: Samples can be taken from the separated impurity particles in the wastewater. (See attached document for details.) Figure 1 - Appendix Figure 5 and attached Figure 7 The top of the separating sleeve 12 has three slots 13, and the inner wall of the top of the separating sleeve 12 has six threaded holes at the slots 13, with bolts 14 passing through the threaded holes. The connecting plate 11 is detachably connected to the slots 13, while the slots 13 and the separating sleeve 12 are integrally formed. The bolts 14 are detachably connected to both the separating sleeve 12 and the connecting plate 11. The sedimentation tank 1 is detachably connected to the sealing cover 5 and the separating sleeve 12. The inner wall of the sealing cover 5 is provided with a sealing ring plate, and the outer wall of the sealing ring plate is attached to the inner wall of the sedimentation tank 1. The diameter of the separating sleeve 12 is smaller than the inner diameter of the sedimentation tank 1.

[0039] After removing the sedimentation tank 1 through the separation sleeve 12, manually pull out each bolt 14 from the threaded hole, so that the connecting plate 11 connected to the sealing cover 5 is disengaged from the slot 13 opened in the separation sleeve 12, thereby disassembling the separation sleeve 12, which facilitates the sampling of impurity particles separated from the sewage, facilitates environmental monitoring, and allows for the disassembly, replacement or cleaning of the separation sleeve 12.

[0041] 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
