Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically a wastewater treatment operation and maintenance device with portable sampling. Background Technology

[0002] In wastewater treatment operation and maintenance, wastewater sampling and testing are necessary to ensure that the wastewater meets treatment standards. Portable sampling devices are widely used in emergency testing and mobile inspections due to their flexibility and portability. During sampling, because wastewater contains a large number of suspended particles or impurities, a filter screen is often installed at the sampling port to perform coarse filtration. However, the filter screen used for coarse filtration is easily clogged by impurities after long-term use and needs to be cleaned in a timely manner to ensure the accuracy of sampling and testing.

[0003] In existing technologies, portable devices for wastewater sampling often employ a fixed filter structure. Cleaning the filter typically requires disassembling the entire filter assembly before rinsing or replacing it. Because the connection between the filter and the device is relatively fixed, each cleaning operation in practical use requires considerable time for disassembly and reassembly, and the process can easily damage components. This makes filter cleaning extremely inconvenient and severely impacts the efficiency of sampling and testing in wastewater treatment operations.

[0004] Therefore, there is an urgent need to propose a wastewater treatment operation and maintenance device with portable sampling capabilities to solve the above problems. Utility Model Content

[0005] To address the problems mentioned in the background section, this utility model provides a wastewater treatment operation and maintenance device with portable sampling capabilities.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment operation and maintenance device with portable sampling, including a sampling mechanism, a detection mechanism installed on the sampling mechanism, a filtration mechanism connected to the bottom of the sampling mechanism, the filtration mechanism including a housing, a liquid extraction pipe connected to one end of the housing, and a liquid inlet pipe connected to the other end of the housing; a sewage discharge pipe connected to the bottom of the housing, and a baffle integrally formed inside the housing on one side above the sewage discharge pipe, the baffle covering half of the inner diameter of the housing, not contacting the housing and leaving reserved space; The baffle has a ring-shaped array of guide ribs integrally formed inside the housing on the side away from the liquid extraction pipe. A filter cartridge mounting shell is slidably installed inside the housing through the guide ribs. The filter cartridge mounting shell contains a filter cartridge body, and a notch is opened on the bottom side of the filter cartridge mounting shell near the baffle.

[0007] Preferably, the sampling mechanism includes a cylinder, a connecting cover is installed on the top of the cylinder, the connecting cover has a central opening and a connecting rod is movably inserted therein, a piston is installed at the bottom of the connecting rod, the piston is located inside the cylinder and its outer diameter matches the inner diameter of the cylinder, and the liquid inlet pipe is connected to the bottom of the cylinder and is integrally formed.

[0008] By clearly defining the complete structure of the sampling mechanism and setting the inlet pipe and the cylinder as an integral molding, the structural stability of the sampling mechanism and the sealing performance of sewage transportation are improved.

[0009] Preferably, the detection mechanism is fixedly connected to the cylinder via a connecting frame, the connecting frame comprising two mounting brackets fixed by bolts.

[0010] By setting the connecting frame as two mounting brackets fixed with bolts, and using them to connect the detection mechanism and the cylinder, the effect of facilitating the disassembly and assembly of the detection mechanism and the cylinder, and making it easy to adjust the installation position of the detection mechanism.

[0011] Preferably, a sealing plug is threaded onto the bottom of the sewage pipe, and the bottom of the sealing plug is provided with an annular boss, the outer diameter of which is larger than the outer diameter of the sewage pipe.

[0012] By connecting the drain pipe and the sealing plug with threads, and setting an annular boss with an outer diameter larger than that of the drain pipe at the bottom of the sealing plug, the sealing effect of the drain pipe is improved, and the sealing plug is easily disassembled for backwashing.

[0013] Preferably, a liquid outlet pipe is installed above one side of the cylinder, and a connecting pipe is movably inserted into one end of the liquid outlet pipe away from the cylinder. One end of the connecting pipe is inserted into the liquid outlet pipe, and the other end is connected to the liquid inlet of the detection mechanism.

[0014] By connecting and installing a liquid outlet pipe on the cylinder, and connecting the liquid outlet pipe and the detection mechanism through a movable insert, the effect of stable delivery of filtered water samples and convenient disassembly and maintenance of the connecting pipe is achieved.

[0015] Preferably, the guide rib extends along the length of the inner wall of the housing, and the side of the guide rib away from the inner wall of the housing is in contact with the outer wall of the filter cartridge mounting shell.

[0016] By extending the guide ribs along the length of the inner wall of the housing and making the guide ribs fit against the outer wall of the filter cartridge mounting housing, the effect of ensuring smooth sliding of the filter cartridge mounting housing within the housing and avoiding displacement that could affect the filtration or backwashing effect is achieved.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features a housing within a filtration mechanism. Inside the housing, a baffle is integrally formed, partially obscuring the baffle's inner diameter and leaving a pre-existing space without contact with the housing. On the side of the housing opposite the suction pipe, a ring of guide ribs is integrally formed. A filter cartridge housing with a notch at its bottom near the baffle is slidably mounted inside the housing via these guide ribs. This allows for cleaning of the filter screen without disassembling the entire filtration component, solving the problems of existing technologies where cleaning the filter screen requires disassembling the entire filtration component, is time-consuming, and easily damages components. Simultaneously, the pre-existing space of the baffle ensures the stability of wastewater filtration, and the guide ribs ensure the precision of the filter cartridge housing's sliding, ultimately improving the efficiency of sampling and testing in wastewater treatment operations.

[0020] 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.

[0021] like Figures 1 to 4 As shown, this utility model provides a wastewater treatment operation and maintenance device with portable sampling, including a sampling mechanism 1, a detection mechanism 2 and a filtration mechanism 3; The sampling mechanism 1 includes a cylinder 11, a connecting cover 12, a connecting rod 13, a piston 131, an outlet pipe 111, a connecting pipe 112, and an inlet pipe 113. The cylinder 11 is a hollow cylindrical structure with the connecting cover 12 fixedly installed on the top. The connecting cover 12 has a central hole and the connecting rod 13 is movably inserted into it. The bottom of the connecting rod 13 extends into the cylinder 11 and the piston 131 is fixedly installed therein. The outer diameter of the piston 131 is adapted to the inner diameter of the cylinder 11. The outlet pipe 111 is connected to the upper side of one side of the cylinder 11, and the connecting pipe 112 is movably inserted into the end of the outlet pipe 11 away from the cylinder 11. The inlet pipe 113 is integrally formed at the bottom of the cylinder 11, and the end of the inlet pipe 113 away from the cylinder 11 has an external thread.

[0022] The above solution achieves stable negative pressure pumping by adapting piston 131 to cylinder 11, improves sealing by integral molding of inlet pipe 113, and facilitates maintenance by movable insertion of outlet pipe 111 and connecting pipe 112, thus solving the problems of poor sealing and unstable water sample delivery in existing devices.

[0023] The detection mechanism 2 is a portable water quality detection module, which is fixed to the outer wall of the cylinder 11 by the connecting frame 21. The connecting frame 21 includes two symmetrical mounting brackets, and the detection mechanism 2 and the cylinder 11 are fixed at both ends by bolts. The liquid inlet of the detection mechanism 2 is inserted and connected to the end of the connecting pipe 112 opposite to the liquid outlet pipe 111.

[0024] The above solution adopts a split design for the connecting frame 21, which facilitates the disassembly and repositioning of the detection mechanism 2. The detection mechanism 2 is directly connected to the connecting pipe 112, reducing water sample contamination and solving the problems of inconvenient disassembly and assembly of the detection mechanism and easy water sample contamination in the existing device.

[0025] The filter mechanism 3 includes a housing 31, a liquid extraction pipe 311, a drain pipe 34, a sealing plug 341, a baffle 313, a guide rib 312, a filter cartridge mounting shell 32, a filter cartridge body 33, and a notch 321. One end of the housing 31 is connected to the liquid extraction pipe 311, and the other end is connected to the liquid inlet pipe 113 via a thread. The bottom of the housing 31 is connected to the drain pipe 34, and the drain pipe 34 is threaded to install the sealing plug 341. The bottom of the sealing plug 341 is provided with an annular boss, the outer diameter of which is larger than the outer diameter of the drain pipe 34. Inside the housing 31, above the drain pipe 34, an integrally formed baffle 313 is provided, which covers the inner diameter of the housing 31. The filter cartridge mounting shell 32 is partially installed in the housing and has a reserved space between it and the inner wall of the housing. The inner wall of the housing 31 on the side of the baffle 313 away from the liquid extraction pipe 311 is provided with an annular array of guide ribs 312. The filter cartridge mounting shell 32 is slidably installed in the housing 31 through the guide groove and the guide ribs 312. The filter cartridge body 33 is fixedly installed inside by snap-fit. The filter cartridge body 33 is made of filter screen winding and welding with no internal filling. Both ends of the filter cartridge body 33 are welded with filter screens of the same mesh size, and the filter screens are made of stainless steel. The bottom of the filter cartridge mounting shell 32 has a notch 321 near the baffle 313. When it contacts the baffle 313, the notch 321 is aligned with the drain pipe 34.

[0026] The above solution is adopted: the baffle 313 provides space to ensure the flow of sewage during sampling, and the guide rib 312 ensures the precise sliding of the filter cartridge mounting shell 32; during backwashing, there is no need to disassemble the filter mechanism 3, and the filter cartridge mounting shell 32 is pushed by the sewage backflow pressure, and impurities are discharged from the sewage pipe 34, which solves the problem of existing fixed filter screens requiring disassembly and assembly, which is time-consuming and easily damaged; the sealing plug 341 is designed to balance sealing and ease of disassembly.

[0027] Working principle and usage process of this utility model: After the filter cartridge body 33 is installed in the filter cartridge mounting shell 32, it is slidably installed in the shell 31. The shell 31 is connected to the liquid inlet pipe 113. The detection mechanism 2 is fixed to the cylinder 11 through the connecting bracket 21. The connecting pipe 112 connects the liquid outlet pipe 111 and the detection mechanism 2. The sealing plug 341 is installed in the sewage pipe 34.

[0028] The suction pipe 311 extends into the sewage, and the connecting rod 13 is pulled up to make the piston 131 slide upward. The sewage enters the cylinder 11 through the suction pipe 311, the reserved space in the shell 31, the notch 321, the filter body 33 and the inlet pipe 113; the water sample is introduced into the detection mechanism 2 through the outlet pipe 111 and the connecting pipe 112.

[0029] During backwashing, unscrew the sealing plug 341, press down the connecting rod 13 to allow the sewage to flow back into the housing 31, and the pressure pushes the filter cartridge mounting shell 32 to contact the baffle 313. The notch 321 aligns with the drain pipe 34, and the sewage backwashes the filter cartridge body 33, and the impurities are discharged from the drain pipe 34. After that, the sealing plug 341 is put back in so that samples can be taken again.
