Description

Technical Field

[0001] The utility model relates to the technical field of sampling tubes, in particular to an online instrument sampling tube. Background Art

[0002] The plant's primary water source is recycled urban water. Because recycled water retains a small amount of sediment during transportation, this sediment can accumulate in the inlet pools of the plant's treatment equipment. After being pressurized by a booster pump, it is delivered to various water points. A sampling line for an online water quality analyzer is installed at the booster pump main pipe, directing water from the main pipe into the analyzer.

[0003] Because the sampling pipe opening is located at the very bottom of the lift pump main pipe, where the water flow rate is reduced at the wall, sediment can easily accumulate, eventually clogging the sampling opening and even the sampling pipe itself. The high sediment content in the water from the lift pump main pipe caused frequent clogging of the sampling pipe, necessitating cleaning and backwashing of the sampling pipe approximately every three days. This significantly increased the workload for instrument maintenance personnel, necessitating an urgent solution.

[0004] The above content is only used to assist in understanding the technical solution of the present invention and does not mean that the above content is the closest prior art. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an online instrument sampling tube, which can not only adjust the position of the water inlet in the lifting pump main pipe to avoid the position of sediment deposition, thereby avoiding sediment blockage, but also has a simple structure and is easy to adjust.

[0008] Preferably, a sealing member is further included; the outer side of the sealing member is fixedly connected to the inner wall of the hollow tube, and the inner side of the sealing member is in contact connection with the outer wall of the water quality sampling tube.

[0009] Preferably, the hollow tube is configured to be in the shape of an inverted trumpet, and a long strip notch is provided at the bottom end of the hollow tube in the vertical direction. There are at least three long strip notches, which are evenly spaced along the circumferential direction of the bottom end of the hollow tube.

[0010] Preferably, the water quality sampling tube is provided with scale lines; the scale lines are used to assist in observing the length of the water quality sampling tube entering the hollow tube.

[0011] Preferably, it further comprises a filter cap arranged at the top end of the water quality sampling tube; the filter cap is arranged in a hemispherical shape and has filter holes.

[0023] Example

[0024] See also Figure 1-2 As shown:

[0025] The utility model provides an online instrument sampling tube, comprising: a lifting pump main pipe 10, a water quality sampling tube 20 and an anti-blocking adjustment component.

[0026] The water supply branch pipe 11 introduces water into the lifting pump main pipe 10, the water quality sampling pipe 20 is connected to the lifting pump main pipe 10, the anti-blocking adjustment component is installed at the connection between the water quality sampling pipe 20 and the lifting pump main pipe 10, and the connection between the water quality sampling pipe 20 and the lifting pump main pipe 10 is sealed, and the water quality sampling pipe 20 and the anti-blocking adjustment component form a plug-in fit.

[0027] In specific applications, the operator changes the position of the water quality sampling tube 20 at the end of the lifting pump main pipe 10 according to the flow conditions of the water flow in the lifting pump main pipe 10, that is, changes the length of the water quality sampling tube 20 in the lifting pump main pipe 10, so as to avoid the silt deposition area of the lifting pump main pipe 10, so that the water quality sampling tube 20 will not be blocked, or the chance of blockage is reduced.

[0028] The anti-blocking adjustment component mainly consists of a manual nut 31 , a hollow tube 32 and a sealing member 33 .

[0029] An external thread is provided on the outside of the hollow tube 32 , and is threadedly connected to the manual nut 31 .

[0030] In specific application, the top end of the hollow tube 32 is connected to the lifting pump main pipe 10; the water quality sampling tube 20 passes through the bottom end of the hollow tube 32 and enters the lifting pump main pipe 10, and the water quality sampling tube 20 and the hollow tube 32 form a nested fit.

[0031] The outer side of the sealing member 33 is fixedly connected to the inner wall of the hollow tube 32, and the inner side of the sealing member 33 is in contact with the outer wall of the water sampling tube 20. The sealing member 33 is generally made of rubber material, and can be a rubber sleeve or a rubber ring.

[0032] The hollow tube 32 is configured to be in an inverted trumpet shape, and a long strip notch is vertically provided at the bottom end of the hollow tube 32 . There are at least three long strip notches, which are evenly spaced along the circumference of the bottom end of the hollow tube 32 .

[0033] With this arrangement, when the manual nut 31 rotates on the hollow tube 32 , it will cause the hollow tube 32 to deform and gather, thereby pressing the seal 33 so that a tight fit is formed between the seal 33 and the outer wall of the water quality sampling tube 20 .

[0034] The water sampling tube 20 further includes a filter cap 22 disposed at the top end thereof. The filter cap 22 is hemispherical in shape and has filter holes 221 thereon.

[0035] The filter cap 22 has an impact zone and a water filtration zone, each occupying half of the cap's area. The impact zone is aligned with the direction of water flow in the lift pump main pipe 10, and the filter holes 221 are located in the water filtration zone. The filter cap 22 is detachably connected to the top of the water sampling tube 20.

[0036] In practical applications, the impact zone of the filter cap 22 faces the water flow in the lift pump main pipe 10, thereby preventing sediment from entering directly through the filter holes 221 when the water flows through the filter cap 22. In addition, the closed arc surface of the impact zone of the filter cap 22 blocks the water flow, causing the water flow to be stirred as it passes through this area. This helps break the balance of sediment originally entrained in the water flow and prevents it from settling.

[0037] The water sampling tube 20 is provided with scale lines 21, which are used to assist in observing the length of the water sampling tube 20 entering the hollow tube 32. An adjustment indicator mark 23 is also included, which is used to indicate the direction of the filter hole 221.

[0038] This arrangement makes it easy for operators to adjust and use the water quality sampling tube 20 , making it easier for them to get started.

[0039] It should be noted that if the embodiments of the present invention involve directional indications such as up, down, left, right, front, back, etc., then such directional indications are only used to explain the relative positional relationship and movement of the various components in a specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indications will also change accordingly. In addition, if the embodiments of the present invention involve descriptions such as "first" and "second", then such descriptions such as "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features specified as "first" and "second" can explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions where both A and B are satisfied. In addition, "multiple" refers to more than two. In addition, the technical solutions of the various embodiments may be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. If the combination of technical solutions is inconsistent or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist. The above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the scope of protection of the present utility model.
