Description

Technical Field

[0002] In the field of environmental protection and water quality monitoring, water body testing is a key link in ensuring water resource safety and ecological health. Among them, water sample pretreatment is an important step before water quality testing. Its main purpose is to remove insoluble substances such as sludge and impurities in the water sample so that subsequent testing and analysis can more accurately reflect the true condition of the water body. Existing water sample pretreatment equipment for water body testing can usually achieve the separation and collection of sludge and impurities. However, when the amount of sludge and impurities accumulates to a certain extent, manual intervention is required to empty these containers, otherwise it may cause the performance of the equipment to decline, and even affect the efficiency and quality of water sample treatment. Therefore, we need to design a water sample pretreatment equipment for water body testing that can automatically discharge accumulated sludge and impurities.

The impurity box is detachably connected to the collecting box and to the first conduit. The sludge box is detachably connected to the collecting box and to the second conduit. The buffer assembly is respectively arranged on the impurity box and the sludge box. When using this equipment to pretreat sewage, impurities enter the impurity box through the first conduit, and sludge enters the sludge box through the second conduit, so that impurities and sludge are collected independently and closed.

[0004] The existing technology is that sludge and impurities can be collected separately and closed, but when the internal sludge and impurities are full, the staff still need to clean them manually, which makes it difficult to improve work efficiency.

[0005] Therefore, it is necessary to design a water sample pretreatment equipment that is highly practical and automatically discharges water for water testing. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-5 The utility model provides a technical solution: a water sample pretreatment device for water body detection, including an operation box 1, a sampling port 15 is fixedly connected to the top of the operation box 1, a sludge mechanism is fixedly connected to the bottom of the operation box 1, the top of the sludge mechanism is fixedly connected to the sedimentation tank 3, the top of the sedimentation tank 3 is fixedly connected to the hollow block 4, the hollow block 4 is connected to the sedimentation tank 3, a filter screen 44 is placed inside the hollow block 4, the top of the filter screen 44 corresponds to a scraping mechanism, a long groove 45 is opened on one side of the hollow block 4, the long groove 45 corresponds to the scraping mechanism, an inclined plate 46 is fixedly connected to one side of the long groove 45, and the bottom of the inclined plate 46 corresponds to the impurity mechanism; when the staff is ready to start water sample pretreatment, the staff first pours the water sample from the sampling port 15 The water sample enters the interior of the operation box 1, passes through the filter 44, and the impurities in the water sample remain on the surface of the filter 44. The water sample reaches the interior of the sedimentation tank 3 and is placed for a period of time. At this time, the mud in the water sample will settle to the bottom of the sedimentation tank 3. At this time, the staff can export the water sample on the upper layer for testing, and the mud on the lower layer flows to the interior of the sludge mechanism. When there is a certain amount of sludge inside, the sludge mechanism will open, and the sludge will automatically be exported to the corresponding place. After the sludge is exported, the sludge mechanism will automatically close again, and the impurities on the top of the filter 44 will flow into the interior of the impurity mechanism through the scraping mechanism through the inclined plate 46. When there are enough impurities inside, the impurity mechanism will start the export mode and export the impurities to the corresponding place. After exporting, it will close again. By providing sludge and impurities that can be automatically discharged, there is no need for staff to manually clean the interior, which saves manpower and improves work efficiency. By providing a scraping mechanism, sludge and impurities can be collected separately, so that corresponding treatment can be done later, maximizing the use of resources.

[0027] The sludge mechanism includes a sludge box 2, a concave block 21 is fixedly connected to the inner bottom of the sludge box 2, a special-shaped block 22 is slidably connected to the inside of the concave block 21, a long block 24 is fixedly connected to the bottom of the special-shaped block 22, a groove 23 is provided inside the special-shaped block 22, a square block 25 is fixedly connected to the inner side of the sludge box 2, a T-shaped slot 26 is provided inside the square block 25, an L-shaped block 27 is slidably connected to the inside of the T-shaped slot 26, one end of the L-shaped block 27 is fixedly connected to a round block 28, the round block 28 and the groove 23 are slidably matched, and the other end of the L-shaped block 27 is fixedly connected to a baffle 29, a through groove is provided at the bottom of the sludge box 2, and the baffle 29 corresponds to the through groove; when the sludge enters the interior of the sludge box 2, the sludge inside the sludge box 2 As the amount of sludge increases, the sludge will push against the long block 24, which will move upward, carrying the special-shaped block 22 upward. The special-shaped block 22 will slide inside the concave block 21, and the groove 23 will also move upward. The round block 28 will not move vertically. When the groove 23 moves upward, the round block 28 will slide to the left inside the groove 23. At this time, the L-shaped block 27 will move to the left inside the T-shaped groove 26, so that the baffle 29 at the bottom will move to the left. The baffle 29 originally blocked the through groove so that the sludge would not flow out. When the amount of sludge inside increases, the baffle 29 moves so that it no longer blocks the through groove, and the sludge inside will flow through the through groove to the corresponding position for subsequent work. By providing a baffle 29 that automatically opens as the amount of sludge increases, the sludge inside the sludge box 2 can be automatically discharged, eliminating the need for manual cleaning by the staff, reducing manpower, and improving work efficiency.

[0028] The groove 23 is hook-shaped, and one end of the hook of the groove 23 is close to the square block 25; the shape of the groove 23 makes it convenient for the L-shaped block 27 to move to the left when the special-shaped block 22 moves upward, and when the special-shaped block 22 moves downward, the L-shaped block 27 moves to the right, that is, when the internal sludge is reduced, the baffle 29 will block the through groove again.

[0029] The interior of the long block 24 is hollow and is made of rubber. The long block 24 is made of hollow rubber and can float above the sludge. Moreover, the rubber is smooth and the sludge will not adhere to its surface. By utilizing the buoyancy of the long block 24 on the sludge, the long block 24 is able to rise, completing the automatic discharge of the sludge and reducing manpower.

[0030] The horizontal block of the L-shaped block 27 is slidably connected to the upper part of the T-shaped slot 26, and the vertical block of the L-shaped block 27 is slidably matched with the lower part of the T-shaped slot 26; the upper part of the L-shaped block 27 is inside the upper part of the T-shaped slot 26 and will not fall, while the lower end of the L-shaped block 27 may slide inside the lower part of the T-shaped slot 26 when the L-shaped block 27 moves.

[0031] The scraping mechanism includes a cylinder 41, which is fixedly connected to one side of the hollow block 4. The output end of the cylinder 41 is connected to a piston rod 42, which passes through the hollow block 4. One end of the piston rod 42 is fixedly connected to a scraper 43, which is located on top of the filter screen 44 and corresponds to the long groove 45. When the staff opens the cylinder 41, the piston rod 42 at the output end extends, carrying the scraper 43 toward the long groove 45, scraping the impurities on the top of the filter screen 44 to the vicinity of the long groove 45, and then entering the impurity mechanism through the inclined plate 46. By providing the scraping mechanism and filter screen 44, the device can collect sludge and impurities separately for subsequent work needs.

[0032] The impurity mechanism includes an impurity box 5, which corresponds to the inclined plate 46. Four springs 51 are fixedly connected to the bottom of the impurity box 5. The other end of the spring 51 is fixedly connected to the inner bottom of the operation box 1. The inner bottom of the operation box 1 is fixedly connected to an electric pump 11. One end of the electric pump 11 is fixedly connected to a pumping pipe 12. The other end of the pumping pipe 12 is fixedly connected to the impurity box 5. The other end of the electric pump 11 is fixedly connected to a discharge pipe 13. A switch contact 14 is provided on the top of the electric pump 11. A contact block 52 is fixedly connected to the bottom of the impurity box 5. The contact block 52 corresponds to the switch contact 14. When the impurity box When the amount of impurities inside the impurity box 5 increases, the weight of the impurity box 5 increases, the impurity box 5 moves downward, and presses the spring 51. The spring 51 has a rebound force. When it continues to descend, the contact block 52 presses the switch contact 14. At this time, the electric pump 11 opens, and the extraction pipe 12 can suck out the impurities inside the impurity box 5 and guide them to the corresponding place through the discharge pipe 13. When the impurities inside become less and less, the weight of the impurity box 5 decreases, and the rebound force of the spring 51 pushes it upward, the contact block 52 leaves the switch contact 14, and the electric pump 11 stops working. By providing the contact block 52 for starting the electric pump 11, the weight of the impurities is used to realize the switching of the electric pump 11, and the impurities inside can be automatically discharged without manual cleaning, thereby improving work efficiency.

[0033] A first magnet 53 is fixedly connected to the bottom of the dust box 5, and a second magnet is fixedly connected to the inner bottom of the operating box 1. The first magnet 53 corresponds to the second magnet. When the dust box 5 moves downward, the first magnet 53 and the second magnet approach each other and attract each other. This ensures that the contact block 52 and the switch contact 14 are in contact. As the dust box 5 loses weight, the rebound force of the spring 51 releases the attraction between the two magnets and moves the dust box 5 upward. During the process of the dust box 5 moving up and down, the inclined plate 46 is always inside the dust box 5, ensuring that impurities can enter the interior of the dust box 5. The provision of two magnets ensures that the device can operate in an orderly manner.
