Description

Technical Field

[0001] This invention belongs to the technical field of wastewater collection and analysis equipment, specifically relating to an integrated wastewater collection and analysis device before the wastewater inlet of an artificial wetland treatment system. Background Technology

[0002] The ecosystem of plants, animals, and microorganisms in wetlands can purify water bodies. Existing technologies create artificial wetland treatment systems by setting up artificial wetlands or plant filters. By constructing water diversion channels, wastewater can be introduced into the artificial wetland treatment system, which can then purify the wastewater, effectively removing excess organic matter, nitrogen and phosphorus, suspended particulate matter, heavy metals, and other pollutants from the water.

[0003] Given the limited processing capacity of this treatment system, the pollutant content of the introduced wastewater should not be too high, and the treatment effect should be evaluated during the process. Typically, wastewater samples are taken before the inlet and sent to a wastewater analysis laboratory for initial water quality analysis using a wastewater analysis device. To avoid errors introduced during wastewater transportation and improve the convenience of wastewater analysis, existing technologies also utilize integrated wastewater collection and analysis devices for long-term automatic sampling and analysis. However, after multiple samplings, the sampling end of this device may become clogged due to the accumulation of suspended particulate matter, algae, fats, and other substances, preventing the water sample from being successfully drawn into the sampling container and causing interruptions in water quality analysis. Furthermore, because the sampling pipeline is difficult to circulate water, the pumping components of the device are prone to overload operation, adversely affecting the service life of the wastewater collection and analysis device. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated wastewater collection and analysis device to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] An integrated wastewater collection and analysis device includes a water quality analyzer and a sample container. The detection end of the water quality analyzer extends into the sample container, which is connected to a sampling mechanism. The discharge port of the sample container is connected to a storage tank. A pressurizing component is provided on one side of the storage tank. The pressurizing component is used to backflush the sample in the storage tank back into the sampling mechanism, clearing the sampling end of the sampling mechanism. This wastewater collection and analysis device is used to sample the water intake channel before the wastewater inlet in a wetland. The sampling mechanism collects a sample of the water in the water intake channel at regular intervals. After the sample enters the sample container, it is analyzed by the water quality analyzer. A valve is provided between the discharge port of the sample container and the storage tank. After the sample analysis is completed, the valve opens, and the sample in the sample container falls into the storage tank. After a suitable amount of sample accumulates in the storage tank, the pressurizing component pushes the sample in the storage tank into the sampling mechanism. The pressurized backflow of sample clears the sampling end of the sampling mechanism, thereby avoiding sampling interruption.

[0007] As a further optimization of the present invention, the storage tank is equipped with a level gauge, and the pressurization component pressurizes the sample liquid in the storage tank after the liquid level in the storage tank rises to a preset value. By setting the level gauge to detect the liquid level in the storage tank, it is possible to determine whether sufficient drainage sample liquid has accumulated in the storage tank.

[0008] As a further optimization of the present invention, the sampling mechanism includes a water pump, a three-way valve connected to the water pump inlet, and a sampling tube. The sampling tube and the liquid storage tank are both connected to the three-way valve, and a cylindrical filter screen is provided at the bottom of the sampling tube.

[0009] As a further optimization of the present invention, a cleaning mechanism is provided on the outside of the filter screen. The cleaning mechanism includes a cleaning brush and a brush head drive component. The brush head drive component is powered by a pressurizing component. While the pressurizing component pressurizes the liquid storage tank, it also drives the cleaning brush to scrape away the blockages on the sampling mechanism through the brush head drive component.

[0010] As a further optimization of the present invention, the brush head drive component includes a mounting plate fixed to the outside of the sampling tube, a rack vertically fixed to one side of the mounting plate, a mounting frame located below the mounting plate, a drive gear rotatably disposed inside the mounting frame and meshing with the rack, a bevel gear transmission mechanism, and a toothed ring. The toothed ring is rotatably disposed at the bottom of the mounting plate, and the cleaning brush and the toothed ring are fixed to each other. The mounting frame is provided with a power component, and the drive gear, under the action of the power component, cooperates with the bevel gear transmission mechanism to drive the toothed ring to rotate.

[0011] As a further optimization of the present invention, the bevel gear transmission mechanism includes two bevel gears and a gear set connected to one of the bevel gears. The bevel gear is used to change the transmission direction of the drive gear, and the gear set meshes with a gear ring to reduce the transmission ratio of the drive gear.

[0012] As a further optimization of the present invention, the power component includes an air cylinder and a drive rod slidably disposed inside the air cylinder, and a piston is provided at one end of the drive rod embedded in the air cylinder, and the other end of the drive rod abuts against the mounting bracket. The air cylinder is fixedly connected to the mounting plate, and the air cylinder is in communication with the pressurization component.

[0013] As a further optimization of the present invention, a reset component is provided between the mounting plate and the mounting bracket, the reset component is used to reset the drive rod, and a positioning component for coupling the mounting bracket is provided at the bottom end of the air cylinder.

[0014] As a further optimization of the present invention, the pressurizing component includes an air pump and a three-way pipe fixed at the exhaust port of the air pump, and the liquid storage tank and the air cylinder are both connected to the three-way pipe.

[0015] As a further optimization of the present invention, the booster component also includes an exhaust valve connected to the three-way pipe.

[0016] The beneficial effects of this invention are as follows:

[0017] 1) This invention uses a storage tank to receive the sample liquid in the sample container. After the three-way valve of the sampling mechanism is connected to the storage tank, the sample liquid in the storage tank is pressed into the sampling mechanism through the pressurizing component. The pressurized backflow of the sample liquid clears the sampling mechanism, avoiding the phenomenon of sampling interruption during long-term initial water quality analysis and reducing the workload of maintenance personnel.

[0018] 2) This invention uses a level gauge to detect the liquid level in the storage tank to determine whether there is enough dredging sample liquid in the storage tank. The sampling mechanism collects sample liquid multiple times and then performs a dredging operation at the sampling end once, avoiding excessively frequent dredging operations and reducing cleaning power consumption.

[0019] 3) To improve the unblocking effect, the present invention sets up a cleaning mechanism outside the filter screen. The pressurizing component pressurizes the sample liquid on the one hand and provides power to the cleaning mechanism on the other hand, so that the drive rod inside the air cylinder drives the mounting frame and drive gear to move down. The drive gear, together with the rack and bevel gear transmission mechanism and the gear ring, drives the cleaning brush to move downward spirally, thereby cleaning the filter screen with the sample liquid discharged from the filter screen, improving the filter screen cleaning effect and unblocking efficiency.

[0020] 4) This invention resets the drive rod and the mounting frame by setting a reset component between the mounting plate and the mounting frame, and sets a magnet at the bottom of the air cylinder. The mounting frame is attracted by the magnet when it is reset and is integrated with the mounting plate and the air cylinder. This avoids excessive use of the reset component during the sampling process, extends the service life of the brush head drive component on the sampling mechanism, and avoids interference between the cleaning brush and the sampling work.

[0028] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] Example

[0030] like Figure 1 and Figure 2As shown, an integrated wastewater collection and analysis device includes a water quality analyzer 1 and a sampling container 2. The detection end of the water quality analyzer 1 extends into the sampling container 2, which is connected to a sampling mechanism 3. The discharge port of the sampling container 2 is connected to a storage tank 4. A pressurization component 5 is provided on one side of the storage tank 4, and a level gauge is installed inside the storage tank 4. After the liquid level in the storage tank 4 rises to a preset value, the pressurization component 5 pressurizes the sample liquid in the storage tank 4, pushing the sample liquid in the storage tank 4 back to the sampling mechanism 3, thus backflushing and clearing the sampling end of the sampling mechanism 3. This wastewater collection and analysis device is used to sample the water intake channel before the wastewater inlet of a wetland. Before sampling, the sampling mechanism 3 is fixed to the edge of the water intake channel, and its sampling end is placed in the water of the channel. During the sampling process, the sampling mechanism 3 collects water samples from the water diversion channel at regular intervals. After the samples enter the sampling container 2, they are analyzed by the water quality analyzer 1. A valve is installed between the discharge port of the sampling container 2 and the storage tank 4. After the sample analysis is completed, the valve opens, and the samples in the sampling container 2 fall into the storage tank 4. Once a suitable amount of sample has accumulated in the storage tank 4, i.e., the liquid level in the storage tank 4 reaches a preset value, the sample in the storage tank 4 is pressurized into the sampling mechanism 3 through the pressurization component 5. In addition, to avoid interference between discharge and injection, the sampling mechanism 3 does not collect samples during the discharge period. The pressurized reflux of the sample clears the sampling mechanism 3, avoiding sampling interruptions during long-term initial water quality analysis and reducing the frequency of maintenance by maintenance personnel.

[0031] Specifically, the wastewater collection and analysis device also includes a housing 8 for housing a water quality analyzer 1, a sample container 2, and a storage tank 4. The sampling mechanism 3 includes a water pump 31 fixed to the side wall of the housing 8. The inlet of the water pump 31 is connected to the upper end of a three-way valve 32, and the lower end of the three-way valve 32 is connected to a sampling tube 33. The drain outlet of the storage tank 4 is inclined downward and connected to the port on the side of the three-way valve 32. A cylindrical filter screen 34 is provided at the bottom of the sampling tube 33. During the sampling process, the upper and lower ends of the three-way valve 32 are open, the water pump 31 is started, and the wastewater in the water intake channel passes through the filter screen 34 to form a sample liquid. The sample liquid passes through the sampling tube 33, the three-way valve 32, and the water pump 31 in sequence and enters the sample container 2. The water quality analyzer 1 analyzes the sample liquid in the sample container 2. During the analysis, the valve of the discharge port of the sample container 2 is closed.

[0032] like Figure 1-4As shown, to further improve the dredging effect, a cleaning mechanism 6 is set on the outside of the filter screen 34. The cleaning mechanism 6 includes a cleaning brush 61 and a brush head drive component. The brush head drive component is powered by a pressurizing component 5. The cleaning brush 61 consists of a cylinder fixed to a toothed ring 67 and brush heads disposed inside the cylinder. The brush heads are divided into multiple groups, and the multiple groups of brush heads are evenly distributed along the circumference of the cylinder. The brush head drive component includes a mounting plate 62 fixed to the outside of the sampling tube 33, a rack 63 vertically fixed to one side of the mounting plate 62, a mounting bracket 64 located below the mounting plate 62, a drive gear 65 rotatably disposed inside the mounting bracket 64 and meshing with the rack 63, a bevel gear transmission mechanism 66, and a toothed ring 67. The toothed ring 67 is rotatably disposed at the bottom of the mounting plate 62, and the cleaning brush 61 is fixedly installed at the bottom of the toothed ring 67. When fixing the sampling mechanism 3, the sampling tube 33 is fixed to the edge of the water diversion channel by the mounting plate 62. Mounting bracket 64 has a top plate and a bottom plate, with a side plate perpendicularly positioned between the top and bottom plates. A drive gear 65 is rotatably connected to the side plate at the front of the mounting bracket 64. To demonstrate the structure of the brush head drive mechanism, this side plate... Figure 3 and Figure 4 As not shown in the diagram, the top and bottom plates of the mounting bracket 64 each have a through hole corresponding to the rack 63. The mounting bracket 64 is equipped with a power component powered by the pressurizing component 5. Under the action of the power component, the drive gear 65 cooperates with the bevel gear transmission mechanism 66 to drive the gear ring 67 and the cleaning brush 61 to rotate. At the same time, through the meshing of the drive gear 65 and the rack 63, the mounting bracket 64 is driven to move downward, so that the cleaning brush 61 moves downward while rotating.

[0033] Specifically, please refer to Figure 3-6 The bevel gear transmission mechanism 66 includes two bevel gears. One bevel gear is fixed to the front side of the drive gear 65, and the other bevel gear is perpendicular to the drive gear 65. The two bevel gears mesh with each other. The bevel gear perpendicular to the drive gear 65 is connected to the gear ring 67 through a gear set. The bevel gear is used to change the transmission direction of the drive gear 65. The gear set meshes with the gear ring 67 to reduce the transmission ratio of the drive gear 65, thereby increasing the rotational speed of the gear ring 67. Figure 5 and Figure 6As shown, the power unit includes an air cylinder 68 and a drive rod 69 slidably disposed inside the air cylinder 68. One end of the drive rod 69, embedded in the air cylinder 68, has a piston, and the other end abuts against the top of the mounting bracket 64. The air cylinder 68 is fixedly connected to the mounting plate 62 and is connected to the pressurizing component 5. Throughout the unblocking process, the port of the three-way valve 32 connected to the storage tank 4 and the sampling tube 33 is open. The pressurizing component 5, on the one hand, pressurizes the storage tank 4, causing the sample liquid to be squeezed out backward from below the sampling tube 33; on the other hand, it provides power to the brush head drive component. Gas is introduced into the cylinder 68 via the pressurizing component 5, causing the piston to drive the drive rod 69 downward. The drive rod 69 presses down on the mounting bracket 64, thereby causing the drive gear 65, bevel gear transmission mechanism 66, and gear ring 67 inside the mounting bracket 64 to move downward. The drive gear 65 rotates under the action of the rack 63, thereby driving the gear ring 67 and cleaning brush 61 to rotate through the bevel gear transmission mechanism 66. This causes the cleaning brush 61 to move downward in a spiral motion, which, together with the sample liquid discharged from the filter screen 34, cleans the filter screen 34.

[0034] Further, please refer to Figure 5 and Figure 6 A reset component is provided between the mounting plate 62 and the mounting bracket 64. The reset component is preferably a reset spring, with both ends fixed to the mounting plate 62 and the mounting bracket 64 respectively. The reset component is used to reset the drive rod 69 and the mounting bracket 64. The bottom end of the air cylinder 68 is provided with a positioning element for coupling the mounting bracket 64. This positioning element is preferably a magnet 7. The mounting bracket 64 has a ferromagnetic metal. After the mounting bracket 64 is reset, it is magnetically fixed by the magnet 7, avoiding excessive use of the reset component, preventing the cleaning brush 61 from falling during sampling, and avoiding interference with sample collection.

[0035] In addition, such as Figure 1 and Figure 2 As shown, the pressurizing component 5 includes an air pump 51 fixed to the side of the housing 8 and a three-way pipe 52 fixed to the exhaust port of the air pump 51. The liquid storage tank 4 and the air cylinder 68 are both connected to the three-way pipe 52. The pressurizing component 5 also includes an exhaust valve 53 connected to the three-way pipe 52. During the resetting process of the mounting bracket 64, the exhaust valve 53 opens to discharge excess gas from the air cylinder 68, preventing the air pressure in the air cylinder 68 from obstructing the resetting of the drive rod 69. The exhaust valve 53 is installed on the three-way pipe 52. It should be noted that the exhaust valve 53 is closed during the operation of the pressurizing component 5, and remains open in all other situations. When the pressurizing component 5 is working, the air pump 51 is used as the air source, and the gas pumped by the air pump 51 is diverted to the liquid storage tank 4 and the air cylinder 68 through the three-way pipe 52. In addition, the exhaust valve 53 can also be installed on the liquid storage tank 4 or the air cylinder 68 to achieve the same exhaust effect.

[0036] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
