Description

Technical Field

[0001] This utility model relates to the field of flow sensor technology, and in particular to a protection device for a wastewater treatment flow sensor. Background Technology

[0002] Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of ordinary people's daily lives. Flow sensors are frequently used for measurement and calculation in wastewater treatment.

[0003] In existing technologies, most flow sensors used in wastewater treatment are directly installed in wastewater pipes without protective devices, and can be damaged by large impurities in the wastewater during use.

[0004] To address this issue, a wastewater treatment flow sensor protection device is proposed. Utility Model Content

[0009] Furthermore, the surface of one end of the flow sensor body is provided with threads, and the surface of one end of the flow sensor body moves through the interior of the annular sealing gasket and is located between two metal wire meshes, and the threads are threaded inside the threaded mounting ring.

[0010] Furthermore, the adjustment device includes an airbag, with two connecting rods fixedly installed on both sides of the bottom of the airbag. A limit plate is fixedly installed on one side of the bottom of each of the two connecting rods. The four connecting rods are divided into two groups, and the two groups of connecting rods are fixedly installed on both sides of the forward and reverse motors, respectively. The two limit plates are located on both sides of the forward and reverse motors, respectively.

[0011] Furthermore, the limiting rod is movable at the bottom of the two limiting plates.

[0012] Furthermore, the mounting assembly includes a fixing plate and an H-shaped support frame. Two mounting plates are fixedly mounted on one side of the fixing plate. A mounting shaft is fixedly mounted on one end of the H-shaped support frame. The two ends of the mounting shaft are respectively mounted on the inner sides of the two mounting plates via bearings.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the airbag is connected to the forward and reverse motors via a connecting rod.

[0015] 2. In this utility model, the flow sensor body is located between two metal wire meshes inside the installation chamber. Wastewater flows through the metal wire meshes on both sides, filtering large impurities without affecting the flow of wastewater. After the control terminal electrically connected to the flow sensor body detects a certain decrease in sensitivity, it starts the forward and reverse motors. The forward and reverse motors drive the installation chamber to rotate through the connecting plate, causing the upstream and downstream metal wire meshes to exchange positions. The water flow washes away the impurities accumulated on the outside of the metal wire meshes, keeping the water flow smooth. This protects the flow sensor body while reducing the impact of impurities on the measurement. Attached Figure Description

[0032] In one embodiment, the adjusting device 4 includes an airbag 401. Two connecting rods 402 are fixedly installed on both sides of the bottom of the airbag 401. A limiting plate 403 is fixedly installed on one side of the bottom of each of the two connecting rods 402. The four connecting rods 402 are divided into two groups.

The positive and negative motor 201 is movably connected to the H-shaped support frame 503 through the cooperation of the support shaft 203 and the collar 505, which facilitates up and down adjustment, so that the flow sensor body 3 is kept at a suitable water level and is not affected by water level changes. The flow sensor body 3 is located inside the installation chamber 1 between two metal wire meshes 101. Sewage flows through the two sides... The metal mesh 101 flows, filtering large impurities without affecting the flow of wastewater. After a period of operation, impurities accumulate on the outer side of the upstream metal mesh 101, affecting the sensitivity of the flow sensor body 3. When the control terminal, which is electrically connected to the flow sensor body 3, detects a certain decrease in sensitivity, it starts the forward and reverse motor 201. The forward and reverse motor 201 drives the installation chamber 1 to rotate through the connecting plate 103, causing the upstream and downstream metal meshes 101 to exchange positions. The water flow washes away the impurities accumulated on the outer side of the metal mesh 101, keeping the water flow smooth and protecting the flow sensor body 3 while reducing the impact of impurities on the measurement.
