Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of turbidity analysis sampling equipment, and specifically discloses a turbidity analyzer sampling device. Background Technology
[0002] A turbidity analyzer is a key device used to detect the turbidity of water. It assesses water cleanliness by measuring the degree of light scattering or absorption by suspended particles in the water, and is widely used in drinking water monitoring, wastewater treatment, and industrial process control. In traditional technology, the sampling device is usually installed by opening a hole in the side wall of a vertical pipe, and the sample water is introduced into the turbidity analyzer control box through a direct connection pipe for testing.
[0003] However, this method of direct sampling relies on natural water flow pressure and does not pre-treat the sample water, which has significant drawbacks:
[0004] Firstly, air and foam can easily mix into the sample water during the sampling process, leading to inaccurate turbidity detection data;
[0005] Secondly, due to the lack of a stable flow design, the water flow often becomes intermittent, affecting the continuity of the detection.
[0006] Third, the lack of an impurity filtration structure allows small stones and other particles in the water to easily enter the pipeline with the sample water, causing blockages and increasing maintenance frequency and costs.
[0007] These problems severely restrict the accuracy of turbidity analysis and the stability of equipment operation. Utility Model Content
[0008] This invention proposes a sampling device for a turbidity analyzer. The top opening design effectively discharges air and foam, while the adjustable bottom discharge port filters impurities, avoiding detection distortion and pipeline blockage. The needle valve, in conjunction with the small-diameter pipe, ensures continuous and stable water flow, eliminating flow interruption.
[0009] This utility model is implemented as follows: a sampling device for a turbidity analyzer, comprising:
[0010] The collecting pipe is a cylindrical tube with an opening at the top and a slag discharge port at one bottom end. A water guide pipe is connected to the lower side of the collecting pipe away from the slag discharge port.

[0012] Small-diameter pipe, which is fixedly connected to the other end of the needle valve;
[0013] A movable plate, which is slidably connected to the inside of the slag discharge port, is used to adjust the size of the slag discharge port.
[0014] In a preferred embodiment of the turbidity analyzer sampling device of this utility model, the diameter of the small-diameter pipe is smaller than the diameter of the water guide pipe.
[0015] As a preferred embodiment of the sampling device for a turbidity analyzer of this utility model, a welding plate is fixedly connected to one end of the outer wall of the collection tube near the water guide pipe. The welding plate is circular and concentrically arranged with the collection tube.
[0016] As a preferred embodiment of the sampling device for a turbidity analyzer according to this utility model, the small-diameter tube is made of corrosion-resistant metal.
[0017] As a preferred sampling device for a turbidity analyzer according to this utility model, the inner diameter of the water guide pipe is 12mm to 16mm, and it is threadedly connected to the needle valve.
[0018] As a preferred sampling device for a turbidity analyzer according to this utility model, the area of the opening accounts for 60%-80% of the cross-sectional area of the collection tube, and the shape is square.
[0019] The beneficial effects of this utility model are:
[0020] This device effectively discharges air and foam through its top opening design, while the adjustable bottom slag discharge port filters impurities, preventing detection distortion and pipeline blockage.

[0027] Please see Figure 1-3 A sampling device for a turbidity analyzer, comprising:
[0028] Collection pipe 1 is a cylindrical tube with an opening 2 at the top. A slag discharge port 6 is provided at one end of the bottom of collection pipe 1. A water guide pipe 3 is connected to the lower side of collection pipe 1 away from the slag discharge port 6.
[0029] Needle valve 4 is located at the other end of water guide pipe 3;
[0030] Small diameter pipe 5, which is fixedly connected to the other end of needle valve 4;
[0031] Movable plate 7 is slidably connected to the inside of slag discharge port 6 and is used to adjust the size of slag discharge port 6.
[0032] In this embodiment: the collection pipe 1 is a cylindrical tube with an opening 2 at the top for discharging air and foam, and a slag discharge port 6 at the bottom for filtering impurities such as small stones. The movable plate 7 adjusts the opening size of the slag discharge port 6 by sliding to accommodate the removal of impurities of different particle sizes. The water guide pipe 3 connects the collection pipe 1 to the needle valve 4. The needle valve 4 ensures continuous flow of sample water by adjusting the flow rate. The small-diameter pipe 5 has a smaller diameter than the water guide pipe 3 and stabilizes the water flow through a tapered design, delivering it to the turbidity analyzer. The welding plate 8 is fixed to the outer wall of the collection pipe 1 to ensure a stable connection between the device and the vertical pipe.
[0033] As a technical optimization of this utility model, the diameter of the small-diameter pipe 5 is smaller than the diameter of the water guide pipe 3.
[0034] In this embodiment: the diameter of the small-diameter pipe 5 is smaller than the diameter of the water guide pipe 3, and the water flow is stabilized and delivered to the turbidity analyzer through the gradual narrowing design.
[0035] As a technical optimization of this utility model, a welding plate 8 is fixedly connected to one end of the outer wall of the collection pipe 1 near the water guide pipe 3. The welding plate 8 is circular and is concentrically arranged with the collection pipe 1.
[0036] In this embodiment: the welding plate 8 is circular and concentrically arranged with the collecting tube 1. When installing the collecting tube 1, a hole is opened in the outer tube bundle, and the collecting tube 1 is inserted into the hole. The welding plate 8 abuts against the outer vertical tube wall, which facilitates welding and makes the device and the vertical tube firmly connected.
[0037] As a technical optimization of this utility model, the small-diameter pipe 5 is made of corrosion-resistant metal.
[0038] In this embodiment, the small-diameter pipe 5 is made of corrosion-resistant metal, which extends its service life and adapts to complex water quality environments such as high salt, high acid and alkali.
[0039] As a technical optimization of this utility model, the inner diameter of the water guide pipe 3 is 12mm to 16mm, and it is threadedly connected to the needle valve 4.
[0040] In this embodiment: the inner diameter of the water guide pipe 3 is 12-16mm, and it is threadedly connected to the needle valve 4 to ensure sealing and prevent water leakage and air from entering.
[0041] As a technical optimization of this utility model, the area of the opening 2 accounts for 60%-80% of the cross-sectional area of the collecting pipe 1, and the shape is square.
[0042] In this embodiment: the area of opening 2 accounts for 60%-80% of the cross-sectional area of collecting pipe 1, and the square design increases the air exhaust area and reduces foam residue.
[0043] The working principle and usage process of this utility model are as follows: When installing the collection tube 1, a hole is opened in the outer bundle tube, and the collection tube 1 is inserted into the hole. The end of the collection tube 1 with the slag discharge port 6 is slightly tilted downwards. The welding plate 8 abuts against the wall of the outer vertical pipe to facilitate welding and make the device and the vertical pipe firmly connected. The sample water enters the collection tube 1 from the vertical pipe. The top opening 2 discharges air and foam. The bottom slag discharge port 6 is adjusted by the movable plate 7 to intercept impurities such as small stones. The sample water flows into the needle valve 4 through the water guide pipe 3. The flow rate is controlled by adjusting the needle valve 4 to ensure continuous and stable water flow. Then the sample water enters the small diameter pipe 5. Its tapered structure maintains the full pipe flow state, eliminates air bubbles and reduces flow rate fluctuations. Finally, the sample water is transported to the turbidity analyzer for detection through the small diameter pipe 5.
