Zero-discharge sewage sampling and detecting equipment

Abstract

This utility model relates to the technical field of wastewater sampling and testing equipment, specifically a wastewater zero-discharge sampling and testing equipment. It includes a main body with two sets of pipe seats for diversion on its outer peripheral surface. A valve body for control of opening and closing is connected to the end of each pipe seat away from the main body via a flange. A U-shaped pipe for guiding flow is connected between the two sets of valve bodies via a flange. During the use of the filter layer inside the cylinder frame, wastewater flowing through the pipe cover can drive the impeller on the ring frame to rotate. The impeller then drives the shaft cylinder seat to rotate via the vertical shaft and four corner blocks. The shaft cylinder seat, in turn, drives the scraper inside the cylinder frame to swing and rotate, facilitating scraping and cleaning of the inner circumference of the filter layer. This removes accumulated debris and reduces clogging of the filter layer, allowing wastewater to pass smoothly through the mesh of the filter layer, facilitating subsequent sampling.

Description

Technical Field

[0001] This utility model relates to the technical field of wastewater sampling and testing equipment, specifically to wastewater zero-discharge sampling and testing equipment. Background Technology

[0002] Water quality monitoring is the process of monitoring and measuring the types, concentrations, and trends of pollutants in water bodies to evaluate water quality. However, wastewater discharge monitoring equipment is frequently used in wastewater discharge testing. Patent CN202411246373.7 discloses a wastewater zero-discharge sampling and testing device. This device uses a lifting platform connected inside the sampling tank. When the lifting platform descends halfway, it lowers the valve stem, which in turn lowers the valve core, opening the valve body and allowing wastewater to enter the sampling tank through the inlet pipe, thus achieving wastewater sampling. However, during the use of this wastewater zero-discharge sampling and testing device, the filter screen in the valve body filters out some impurities as wastewater passes through. These impurities accumulate inside the filter screen, easily causing blockage and affecting subsequent sampling. Therefore, we propose a wastewater zero-discharge sampling and testing device. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a wastewater zero-discharge sampling and testing device.

[0004] The technical solution adopted by this utility model to solve its technical problem is a wastewater zero-discharge sampling and testing device, including a main body. The outer peripheral surface of the main body is provided with a pipe seat for diversion, and there are two sets of pipe seats. The end of the pipe seat away from the main body is connected to a valve body for controlling opening and closing through a flange. The two sets of valve bodies are connected to a U-shaped pipe for guiding flow through a flange. The outer peripheral surface of the U-shaped pipe is integrally constructed with a vertical pipe for guiding flow. The end of the vertical pipe away from the U-shaped pipe is equipped with a pipe cover. The bottom surface of the pipe cover is bolted with a secondary tank. The inner side of the secondary tank is bolted with a cylindrical frame for support. The inner periphery of the cylindrical frame is equipped with a filter screen layer for wastewater filtration.

[0005] The inner side of the cylinder frame is rotatably mounted with a scraper that abuts against the filter layer, and the inner side of the pipe cover is fitted with a straight ring frame for support by screws. The side of the straight ring frame near the auxiliary tank is rotatably mounted with an impeller body for transmission, and the end of the impeller body away from the straight ring frame is fitted with a rotating shaft. The end of the rotating shaft away from the impeller body has a four-corner block integrally constructed, and the end of the scraper near the four-corner block is fitted with a shaft cylinder seat that engages with the four-corner block.

[0006] By adopting the above technical solution, during the use of the sewage sampling and testing equipment, the sewage discharged from the main body is diverted by two sets of pipe seats and U-shaped pipes, and the impact force generated by the sewage flow is reduced. At the same time, the opening and closing of the valve body can be used to control whether the sewage enters the U-shaped pipe, which facilitates subsequent sampling and testing. When the sewage enters the auxiliary tank from the U-shaped pipe through the vertical pipe during sampling, the filter screen layer on the cylinder frame in the auxiliary tank can provide a certain filtration performance for the sewage, thereby reducing the impact of garbage and debris on subsequent sampling.

[0007] During the use of the filter layer inside the cylinder frame, the sewage flowing through the inside of the pipe cover drives the impeller on the straight ring frame to rotate. The impeller then drives the shaft cylinder seat to rotate through the vertical shaft and the four corner blocks. The shaft cylinder seat drives the scraper inside the cylinder frame to swing and rotate, making it easy to scrape and clean the inner circumference of the filter layer with the scraper. This also moves the accumulated garbage and debris and reduces the possibility of clogging the filter layer, allowing the sewage to pass through the mesh of the filter layer smoothly, which is convenient for subsequent sampling. The two can be separated simply by unscrewing the bolts that fix the pipe cover and the auxiliary tank, making it easy to clean the garbage and debris accumulated in the filter layer. The operation is simple and convenient.

[0008] Specifically, the bottom discharge end of the auxiliary tank is equipped with a corrugated pipe for guiding the flow, and the end of the corrugated pipe away from the auxiliary tank is equipped with a bend. The end of the bend away from the corrugated pipe is connected to a sampling tank for sewage sampling through a flange.

[0009] By adopting the above technical solution, the corrugated pipe at the bottom of the auxiliary tank is easy to extend and retract, making the auxiliary tank easier to disassemble and assemble. The bend facilitates the flow of sewage, allowing the sewage to pass through the bend more smoothly into the sampling tank during sampling, which facilitates subsequent sewage sampling and testing.

[0010] Specifically, the outer wall surface of the scraper is fitted with a rubber strip that abuts against the filter layer by screws.

[0011] By adopting the above technical solution, the rubber strip has good elasticity, which facilitates the improvement of the scraper's effect on cleaning the filter layer.

[0012] Specifically, a rubber gasket that fits the secondary tank is glued to the end of the pipe cap near the secondary tank.

[0013] By adopting the above technical solution, the rubber gasket has good elasticity, which facilitates the improvement of the tightness of the connection between the pipe cover and the auxiliary tank.

[0014] Specifically, the outer circumferential surface of the cylinder frame is bonded with a rubber ring that fits the inner circumference of the auxiliary tank.

[0015] By adopting the above technical solution, the rubber ring has a certain degree of elasticity, which facilitates protection when the cylinder frame and the auxiliary tank come into contact with each other, thereby reducing the damage caused by rubbing and collision.

[0016] Specifically, the outer peripheral surface of the auxiliary tank is fitted with a handle for lifting, and there are multiple sets of handles.

[0017] By adopting the above technical solution, the handle makes it easy to lift the auxiliary tank, thus making subsequent disassembly and maintenance of the auxiliary tank more convenient.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The technical solution of this application, through the design of pipe seats, valve bodies, U-shaped pipes, vertical pipes, pipe covers, auxiliary tanks, cylinder frames, and filter screen layers, utilizes two sets of pipe seats and U-shaped pipes to divert sewage discharged from the main body and reduce the impact force generated by sewage flow during the use of sewage sampling and testing equipment. At the same time, the opening and closing of the valve body can control whether sewage enters the U-shaped pipe, which facilitates subsequent sampling and testing. Furthermore, when sewage enters the auxiliary tank from the U-shaped pipe through the vertical pipe, the filter screen layer on the cylinder frame in the auxiliary tank provides a certain filtration performance for the sewage, thereby reducing the impact of garbage and debris on subsequent sampling.

[0020] 2. The technical solution of this application, through the design of a scraper, a straight ring frame, an impeller body, a rotating shaft, four corner blocks, and a shaft cylinder seat, allows the impeller body on the straight ring frame to rotate when the sewage flows through the inside of the pipe cover during the use of the filter screen layer inside the cylinder frame. Subsequently, the impeller body can drive the shaft cylinder seat to rotate through the vertical shaft and four corner blocks, and the shaft cylinder seat can drive the scraper inside the cylinder frame to swing and rotate. This facilitates the scraping and cleaning of the inner circumference of the filter screen layer by the scraper, and also moves the accumulated garbage and debris, reducing the possibility of clogging of the filter screen layer. This allows the sewage to pass smoothly through the mesh of the filter screen layer, facilitating subsequent sampling. Moreover, the two can be separated simply by unscrewing the bolts fixing the pipe cover and the auxiliary tank, making it easy to clean the garbage and debris accumulated in the filter screen layer. The operation is simple and convenient. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Please see Figure 1-3 This utility model provides a technical solution: a wastewater zero-discharge sampling and testing device, including a main body 1. The outer circumferential surface of the main body 1 is provided with pipe seats 2 for diversion, and there are two sets of pipe seats 2. The end of the pipe seat 2 away from the main body 1 is connected by a flange to a valve body 3 for controlling opening and closing. A U-shaped pipe 4 for guiding flow is connected between the two sets of valve bodies 3 by a flange. A vertical pipe 5 for guiding flow is integrally constructed on the outer circumferential surface of the U-shaped pipe 4, and a pipe cover 6 is fitted at the end of the vertical pipe 5 away from the U-shaped pipe 4. A secondary tank 7 is bolted to the bottom surface of the pipe cover 6, and a secondary tank 7 is bolted to the inside of the secondary tank 7. The support cylinder 8 has a filter screen layer 9 for sewage filtration mounted on its inner circumference. A scraper 10 is rotatably mounted on the inner side of the cylinder 8 to abut against the filter screen layer 9. A straight ring frame 11 for support is mounted on the inner side of the pipe cover 6 by screws. An impeller body 12 for transmission is rotatably mounted on the side of the straight ring frame 11 near the auxiliary tank 7. A rotating shaft 13 is mounted on the end of the impeller body 12 away from the straight ring frame 11. A four-corner block 14 is integrally constructed on the end of the rotating shaft 13 away from the impeller body 12. A shaft cylinder seat 15 that engages with the four-corner block 14 is mounted on the end of the scraper 10 near the four-corner block 14.

[0028] During use, when the sewage sampling and testing equipment is used, the sewage discharged from the main body 1 is diverted by two sets of pipe seats 2 and U-shaped pipes 4, and the impact force generated by the sewage flow is reduced. At the same time, the opening and closing of the valve body 3 can be used to control whether the sewage enters the U-shaped pipe 4, which is convenient for subsequent sampling and testing. When the sewage enters the auxiliary tank 7 from the U-shaped pipe 4 through the vertical pipe 5, the filter screen layer 9 on the cylinder frame 8 in the auxiliary tank 7 can provide a certain filtration performance for the sewage, thereby reducing the impact of garbage and debris on subsequent sampling.

[0029] During the use of the filter layer 9 inside the cylinder frame 8, when the sewage flows through the inside of the pipe cover 6, it can drive the impeller body 12 on the straight ring frame 11 to rotate. Then, the impeller body 12 can drive the shaft cylinder seat 15 to rotate through the vertical shaft and the four corner blocks 14. The shaft cylinder seat 15 drives the scraper 10 inside the cylinder frame 8 to swing and rotate, which makes it convenient to use the scraper 10 to scrape and clean the inner circumference of the filter layer 9, and to move the accumulated garbage and debris, reducing the clogging of the filter layer 9. This allows the sewage to pass through the mesh of the filter layer 9 smoothly, which is convenient for subsequent sampling. The two can be separated by simply unscrewing the bolts between the fixing pipe cover 6 and the auxiliary tank 7, which makes it easy to clean the garbage and debris accumulated in the filter layer 9. The operation is simple and convenient.

[0030] like Figure 1 As shown, the bottom discharge end of the auxiliary tank 7 is equipped with a corrugated pipe 16 for guiding the flow, and the end of the corrugated pipe 16 away from the auxiliary tank 7 is equipped with a bend 17. The end of the bend 17 away from the corrugated pipe 16 is connected to a sampling tank 18 for sewage sampling through a flange.

[0031] When in use, the corrugated pipe 16 at the bottom of the auxiliary tank 7 is easy to extend and retract, making it easier to disassemble and assemble the auxiliary tank 7. The bend 17 facilitates the flow of sewage, allowing the sewage to pass through the bend 17 more smoothly into the sampling tank 18 during sampling, which facilitates subsequent sewage sampling and testing.

[0032] like Figure 2 As shown, the outer wall surface of the scraper 10 is fitted with a rubber strip 19 that abuts against the filter layer 9 by screws.

[0033] When in use, the rubber strip 19 has good elasticity, which makes it easier to improve the effect of scraping and cleaning the filter layer 9 by the scraper 10.

[0034] like Figure 1 and Figure 3 As shown, a rubber gasket 20 that fits the sub-tank 7 is glued to one end of the pipe cap 6 near the sub-tank 7.

[0035] When in use, the rubber gasket 20 has good elasticity, which facilitates the tightness of the connection between the pipe cap 6 and the auxiliary tank 7.

[0036] like Figure 2 As shown, a rubber ring 21 that fits the inner circumference of the auxiliary tank 7 is bonded to the outer circumference of the cylinder frame 8.

[0037] When in use, the rubber ring 21 has a certain degree of elasticity, which facilitates protection when the cylinder frame 8 and the auxiliary tank 7 come into contact with each other, thereby reducing damage caused by rubbing.

[0038] like Figure 1 As shown, the outer peripheral surface of the auxiliary tank 7 is fitted with a handle 22 for lifting, and there are multiple sets of handles 22.

[0039] When in use, the handle 22 makes it easy to lift the secondary tank 7, which makes it more convenient to disassemble and maintain the secondary tank 7 later.

[0040] The working principle and usage process of this utility model are as follows: During the use of the sewage sampling and testing equipment, the sewage discharged from the main body 1 is diverted by two sets of pipe seats 2 and U-shaped pipes 4, reducing the impact force generated by the sewage flow. At the same time, the opening and closing of the valve body 3 can control whether the sewage enters the U-shaped pipe 4, facilitating subsequent sampling and testing. When the sewage enters the auxiliary tank 7 from the U-shaped pipe 4 through the vertical pipe 5, the filter layer 9 on the cylinder frame 8 in the auxiliary tank 7 provides a certain filtration performance for the sewage, thereby reducing the impact of garbage and debris on subsequent sampling. During the use of the filter layer 9 inside the cylinder frame 8, when the sewage flows through the inside of the pipe cover 6, it can drive the impeller body 12 on the straight ring frame 11 to rotate. Subsequently, the impeller body 12 can drive the vertical shaft and the four corner blocks 14 to rotate. The shaft holder 15 rotates accordingly, and the scraper 10 inside the cylinder frame 8 swings and rotates accordingly. This allows the scraper 10 to scrape and clean the inner circumference of the filter layer 9, and moves the accumulated garbage and debris, reducing the chance of clogging the filter layer 9. This allows the sewage to pass smoothly through the mesh of the filter layer 9, facilitating subsequent sampling. The coarsely filtered sewage then passes through the corrugated pipe 16 and the bend pipe 17 into the sampling tank 18, facilitating the sampling of sewage using the internal structure of the sampling tank 18 and subsequent testing. The valve body 3 is used to seal the U-shaped pipe 4, and the bolts between the fixing pipe cover 6 and the auxiliary tank 7 are unscrewed to separate the two, making it easy to clean the garbage and debris accumulated in the filter layer 9. The operation is simple and convenient.
