Description

Technical Field

[0001] The utility model relates to sewage treatment, in particular to a water sample collection unit embedded in the panel of a sewage enrichment instrument. Background Art

[0002] In today's globalization, the problem of drug abuse has become a severe global challenge. It not only threatens public safety but also has a significant impact on social order. To effectively monitor and evaluate the use of drugs, the technology of detecting drugs in sewage has been developed as an important monitoring means. By analyzing the drug residues in untreated domestic sewage, this technology can quantitatively analyze the drug consumption, types, and the scale of the drug-using population in a specific area, providing a scientific basis for revealing the distribution law and usage of drug use.

[0003] In the existing technologies of sewage enrichment, there are mainly two layout methods for operating components: one is to set the components outside the casing, and the other is to embed them inside the casing. Each method has its inherent advantages and disadvantages.

[0004] For the operating components set outside, such as the portable automatic equipment for enriching drugs in sewage described in Chinese Patent CN217466423U, they are easy to access and operate directly. However, this design has the following disadvantages: the external components are easily scratched or impacted accidentally, resulting in damage or failure of functions. The components are directly exposed to the environment and may be affected by dust, moisture, and other pollutants, increasing the maintenance requirements and the risk of equipment failure.

[0005] On the other hand, although the design method of placing the operating components inside the casing provides better physical protection and reduces the influence of environmental factors, it also brings a series of problems: inconvenient operation, users need to open the casing or small door to operate, which increases the operation steps and time. The space limitation inside the casing may affect the user's operation vision and accuracy, especially in the case of fine adjustment. Frequent opening of the casing may reduce the sealing performance of the equipment and affect its waterproof and dustproof capabilities. Summary of the Utility Model

[0006] To solve the above technical problems or one of them, the utility model provides a water sample collection unit embedded in the panel of a sewage enrichment instrument. The technical solution adopted by the utility model is:

[0007] A water sample collection unit embedded in the panel of a sewage enrichment instrument, including a water sample metering cup. A peristaltic pump pumps water samples from a water sample storage bucket directly or indirectly to the water sample metering cup. Different from the prior art, a water sample collection hole is opened on the panel of the sewage enrichment instrument, and a water sample collection housing connected to the water sample collection hole is fixedly arranged inside the panel of the sewage enrichment instrument. An operation space for conveniently taking and placing the water sample metering cup is formed inside the water sample collection housing.

[0008] Further, a fixing plate is fixedly arranged above the water sample collection housing. A first guide rail with a vertical stroke is fixedly arranged on the fixing plate. The first guide rail is slidably matched with a first slider. An installation block is fixedly arranged on the first slider. An injection pipe, a sampling pipe and two tungsten rods that can extend into or be withdrawn from the upper through hole of the water sample collection housing are installed on the installation block. The length of the injection pipe is less than the length of the sampling pipe. The injection pipe is directly or indirectly connected to the outlet of the peristaltic pump. The sampling pipe is directly or indirectly connected to a downstream component. The two tungsten rods are connected to a controller for controlling the peristaltic pump. Coincident first and second strip-shaped holes with a vertical length direction are opened on the installation block and the panel of the sewage enrichment instrument. The rod portion of a handle passes through the second strip-shaped hole and the first strip-shaped hole and is fixedly connected to the installation block.

[0009] Further, when the handle is lifted to the upper ends of the first and second strip-shaped holes, the lower end of the sampling pipe is higher than the cup mouth of the water sample metering cup. When the handle is pressed down to the lower ends of the first and second strip-shaped holes, the lower end of the sampling pipe is close to the bottom of the water sample metering cup.

[0010] Further, the length of the tungsten rod is less than the length of the injection pipe. The length difference between the tungsten rod and the sampling pipe is proportional to the volume of the water sample.

[0011] Further, the sampling pipe is connected to a multi-channel injection pump of the sewage enrichment instrument. The multi-channel injection pump adds a pH value regulator into the water sample metering cup through the sampling pipe, blows air for mixing or extracts acidified water samples to supply a downstream treatment unit or treatment process.

[0012] Further, an iron baffle is fixedly connected to the upper end of the fixing plate, and a magnet is fixedly arranged on the upper end of the installation block.

[0013] Further, the handle is fixedly connected to a screw rod. The screw rod passes through the second strip-shaped hole and the first strip-shaped hole 3031 and is screwed to the installation block.

[0014] Further, the extrusion rotor and extrusion hose of the peristaltic pump are arranged outside the panel of the sewage enrichment instrument.

[0015] Compared with the prior art, the beneficial technical effects of the present utility model are:

[0016] Operational convenience: By opening a water sample collection hole on the panel of the sewage enrichment instrument and fixing the water sample collection housing, users can directly access the water sample measuring cup without frequently opening or closing the casing, simplifying the operation steps and improving work efficiency.

[0017] Equipment protection: The design of the water sample collection housing provides physical protection for the operating components, reducing damage to the components caused by accidental scratches or environmental factors, thereby extending the service life of the equipment.

[0018] Easy maintenance: The optimized component layout and easily accessible operating space make maintenance and cleaning more convenient, reducing maintenance costs.

[0019] Improved accuracy: Due to the integrated design of the components, the line of sight obstruction and space limitation during operation are reduced, improving the operation accuracy.

[0020] Enhanced sealing: Avoiding the reduction of sealing performance caused by frequently opening the casing ensures the waterproof and dustproof capabilities of the equipment. Description of the drawings

[0028] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0029] As Figures 1-4 shown, a water sample collection unit embedded in the panel of a sewage enrichment instrument, a water sample collection unit embedded in the panel of a sewage enrichment instrument, includes a water sample quantitative cup 301. A peristaltic pump 400 pumps water samples from a water sample storage bucket directly or indirectly to the water sample quantitative cup 301. A water sample collection hole 102 is opened on the panel 100 of the sewage enrichment instrument, and a water sample collection housing 302 connected to the water sample collection hole 102 is fixedly arranged inside the panel 100 of the sewage enrichment instrument. An operation space for conveniently taking and placing the water sample quantitative cup 301 is formed inside the water sample collection housing 302.

[0030] Above the water sample collection housing 302, a fixed plate 303 is fixedly installed. On the fixed plate 303, a first guide rail 304 with a vertical stroke is fixedly installed. The first guide rail 304 is slidably engaged with a first slider 305. On the first slider 305, an installation block 306 is fixedly installed. On the installation block 306, a sampling tube 307, a sample outlet tube 308, and two tungsten rods 309 that can extend into or be withdrawn from the upper through hole 3021 of the water sample collection housing 302 are installed. The length of the sampling tube 307 is less than the length of the sample outlet tube 308. The sampling tube 307 is directly or indirectly connected to the outlet of the peristaltic pump 400. The sample outlet tube 308 is directly or indirectly connected to downstream components. The two tungsten rods 309 are connected to the controller that controls the peristaltic pump 400 for monitoring the water sample level, controlling the pumping action of the peristaltic pump, and also preventing water sample overflow. Coincident first elongated holes 3031 and second elongated holes 103 with a vertical long direction are provided on the installation block 306 and the sewage enrichment instrument panel 100. The rod portion of the handle 310 passes through the second elongated hole 103 and the first elongated hole 3031 and is fixedly connected to the installation block 306.

[0031] When the handle 310 is lifted to the upper ends of the first elongated hole 3031 and the second elongated hole 103, the lower end of the sample outlet tube 308 is higher than the cup mouth of the water sample measuring cup 301. When the handle 310 is pressed down to the lower ends of the first elongated hole 3031 and the second elongated hole 103, the lower end of the sample outlet tube 308 is close to the bottom of the water sample measuring cup 301.

[0032] When it is necessary to replace or clean the water sample measuring cup 301, the installation block 306 and the components thereon (sampling tube, sample outlet tube, tungsten rod) are lifted above the water sample collection housing 302 through the handle 310. After the operation is completed, the handle 310 is released. The installation block 306 and the components thereon slide back into the operation space and return to the working position under the action of the guide rail 304 and the slider 305.

[0033] The length of the tungsten rod 309 is less than the length of the sampling tube 307. The length difference between the tungsten rod 309 and the sample outlet tube 308 is proportional to the volume of the water sample. This means that by adjusting the length difference between these two tubes, the required volume of the water sample can be changed. For example, if a larger volume of water sample needs to be collected, the tungsten rod 309 can be adjusted upward to make the gap between it and the sample outlet tube 308 larger.

[0034] The sample delivery tube 308 is connected to the multi-channel injection pump of the sewage enrichment instrument. The multi-channel injection pump adds a pH regulator into the water sample measuring cup 301 through the sample delivery tube 308, blows air to mix it, or extracts the acidified water sample to supply the downstream processing unit or process. The sample delivery tube also functions to blow air, which is used to mix the water sample after adding acid. To achieve a better air-blowing and mixing effect, this design provides an integrated and automated water sample treatment solution. By precisely controlling the addition, mixing, and extraction of the pH regulator and the water sample, the efficiency and accuracy of the experiment are improved. At the same time, through automated control, the need for manual operation is reduced, and the risk of operation errors is lowered.

[0035] In this embodiment, an iron baffle 311 is fixedly connected to the upper end of the fixed plate 303, and a magnet 312 is fixedly provided at the upper end of the mounting block 306. Through the adsorption of the magnet, the mounting block 306 and the sampling tube 307, sample delivery tube 308, and two tungsten rods 309 thereon are stopped at the upper ends of the second strip-shaped hole 103 and the first strip-shaped hole 3031. When the component is pulled up, the magnet attracts the pulled-up component to ensure that the component remains stable when not in use. When pulling down, only a slight force is required to disengage from the adsorption of the magnet, realizing the rapid release of the component. This design provides a simple, rapid, and reliable way to fix and release the key components of the water sample collection unit, optimizing the experimental operation process and potentially reducing the risk of operation errors.

[0036] In another preferred embodiment, the handle 310 is fixedly connected to a screw rod. The screw rod passes through the second strip-shaped hole 103 and the first strip-shaped hole 3031 and is screwed to the mounting block 306. By tightening the handle 310, the mounting block 306 and the sampling tube 307, sample delivery tube 308, and two tungsten rods 309 thereon can be stopped at the upper ends of the second strip-shaped hole 103 and the first strip-shaped hole 3031. This design provides a simple and reliable method to position and fix the key components, enabling the user to easily adjust the height of the mounting block 306 to meet different operation requirements. While maintaining the accuracy and stability of the component positioning, this design provides a more flexible and user-friendly operation method, which helps to improve the working efficiency and adaptability of the water sample collection unit.

[0037] In this embodiment, the extrusion rotor and extrusion hose of the peristaltic pump 400 are arranged outside the panel 100 of the sewage enrichment instrument. Since the extrusion hose is arranged outside the panel, it becomes more convenient and rapid to replace the extrusion hose. The user can replace it without disassembling other components or opening the machine case, which is a practical and efficient design choice. It provides convenience for the user while ensuring the high performance and stability of the device.

[0038] Generally speaking, the water sample collection unit embedded in the panel of the sewage enrichment instrument in this embodiment has the following beneficial effects:

[0039] 1. Operational convenience: Through the water sample collection hole opened on the panel of the sewage enrichment instrument and the fixedly installed water sample collection housing, users can conveniently take and place the water sample measuring cup, simplifying the operation steps.

[0041] 3. Precise liquid level control: Using the tungsten rod as a liquid level sensor, the controller can accurately monitor the water sample liquid level and automatically control the pumping action of the peristaltic pump to prevent water sample overflow and ensure collection accuracy.

[0042] 4. Integrated functions: The outlet tube is connected to a multi-channel injection pump to achieve integrated operations such as adding pH regulator to the water sample measuring cup, mixing, and extracting acidified water samples.

[0043] 5. Improved automation level: Automatic control reduces manual operation, reduces the risk of operation errors, and improves experimental efficiency and accuracy.

[0044] 6. Flexibility and adaptability: By adjusting the length difference between the tungsten rod and the outlet tube, different volumes of water sample collection requirements can be met.

[0045] 7. Easy replacement of components: The extrusion rotor and hose of the peristaltic pump are set outside the panel, facilitating quick replacement of the hose and reducing maintenance time.

[0046] 8. Stability and safety: The mounting block and its components are fixed by magnetic adsorption or screw connection to ensure the stability of the components when not in use and achieve quick release at the same time.

[0047] 9. User-friendly: The design takes into account the convenience of user operation, and improves the user experience through a simplified mechanical structure and an automatic control system.

[0048] 10. Improvement of equipment performance: The overall design improves the working efficiency and adaptability of the water sample collection unit, ensuring the high performance and stability of the equipment.
