TECHNICAL FIELD

[0001] The present application belongs to the field of automatic measurement of water quality analyzers, and particularly relates to a water quality analyzer sensor protection device. BACKGROUND

[0002] Waste water is polluted water produced in the process of industrial production, and its discharge is a prominent environmental problem. At present, the pollution and destruction of water environment in China are very serious. It is of great significance to realize the standard discharge and recycling of organic industrial waste water for the protection of the environment.

[0003] The measurement accuracy of a water quality analyzer is a key environmental protection process parameter for ensuring the normal operation of waste water treatment and the standard of water quality, and plays a key role in whether the waste water treatment can meet the standard and supervises and ensures the normal operation of the entire waste water treatment process.

[0004] The existing water quality analyzer has the following problems in the running process:

[0005] 1. The analyzer sensor connecting sleeve is in the sludge for a long time, which causes the surface of the probe to be dirty and affects the measurement value. The maintenance personnel need to clean the probe every half month or 10 days, which brings a great workload to the maintenance personnel.

[0006] 2. Since the measurement medium is waste water produced in the process of production, the water contains many impurities and harmful corrosive substances, which damages the surface film of the analyzer sensor, affects the measurement, and shortens the service life of the probe.

[0007] 3. After the stirrer is operated, water vortex is formed, the analyzer sensor is in the vortex, and the probe is abraded by the water vortex, which shortens the service life of the probe. CONTENT OF THE INVENTION

[0008] The water quality analyzer sensor protection device of the present application solves the problems of the existing water quality analyzer in the running process, prolongs the service life of the water quality analyzer sensor, and reduces the workload of manual maintenance. The present application adopts the following technical scheme:

[0009] A water quality analyzer sensor protection device, comprising a fixing frame, the fixing frame is installed on the edge of a waste water tank, a protection sleeve is arranged on the fixing frame, an analyzer sensor is arranged in the protection sleeve, the inner diameter of the protection sleeve matches the diameter of the analyzer sensor, drainage holes are arranged on the protection sleeve, the drainage holes are arranged in multiple rows and are evenly distributed along the circumference of the protection sleeve, and a drain valve is arranged at the lower end of the protection sleeve.

[0010] Further, the drain valve is a one-way valve for draining water outside the protection sleeve.

[0011] Furthermore, the lower end of the protective sleeve is fitted with a beveled pipe opening via fasteners to guide the rapid discharge of sewage.

[0012] Furthermore, the angle between the end bevel of the beveled pipe opening and the central axis of the pipe is in the range of 10°-30°.

[0013] Furthermore, the fastener is a pipe clamp.

[0014] Furthermore, the top of the protective sleeve is provided with a fixing device for fixing the analyzer cable.

[0015] Furthermore, the fixing device is a hose clamp, which has a rubber liner.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. Reduce sludge adhesion: Wastewater enters the casing through the drainage hole and is discharged by the drain valve, avoiding direct contact between the sensor and the sludge, extending the cleaning cycle to 2 months.

[0018] 2. Reduced wear: The drainage holes disperse the impact of water vortex, extending the sensor replacement cycle to 2 years.

[0019] 3. Inclined design solves the siltation problem: The inclined angle at the end of the protective sleeve guides the flow of sewage and avoids siltation.

[0020] 4. Modular structure reduces installation costs and has wide applicability: It uses PVC pipes and standard fittings, making installation convenient and inexpensive. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0026] A water quality analyzer sensor protection device includes a mounting bracket 4, which is bolted to the edge of a wastewater tank 6. A protective sleeve 3 is provided on the mounting bracket 4. The protective sleeve 3 is made of corrosion-resistant, high-strength PVC pipe with an outer diameter of Φ32mm, a wall thickness of 3mm, and a total length of 25cm.

[0027] Five rows of vertically arranged circular holes are evenly spaced along the circumference of the protective sleeve 3, 15cm from the top. Each row contains three drainage holes 12 with a diameter of Φ8mm, for a total of 15 holes. The spacing between adjacent rows of drainage holes 12 is 3cm to ensure that wastewater enters the sleeve evenly.

[0028] Drain valve 8 is installed at the bottom of protective sleeve 3. Drain valve 8 is a one-way valve made of corrosion-resistant material with a valve port diameter of Φ10mm to ensure that water can only be discharged in one direction and prevent backflow of external sewage.

[0029] The lower end of the protective sleeve 3 is equipped with a beveled pipe opening 9 via a pipe clamp 10. The angle between the beveled surface at the end of the beveled pipe opening 9 and the central axis of the pipe is 10°, and the beveled surface is opposite to the direction of sewage flow. According to the principle that the pressure is greater where the flow velocity is higher, the water flow velocity at the beveled pipe opening 9 is greater, which can push the sewage in the protective sleeve 3 outward, effectively reducing the deposition of sludge at the bottom of the sleeve. Moreover, the direction of the beveled angle is consistent with the direction of water flow, which is used to guide the sewage to be discharged quickly.

[0030] The top of the protective sleeve 3 is equipped with a hose clamp 11, which has a rubber liner to fix the analyzer cable 2.

[0031] An analyzer sensor 5 is inserted into the protective sleeve 3. The analyzer cable 2, which passes through the top of the protective sleeve 3, is fixed to the top of the protective sleeve 3 by a stainless steel hose clamp 11. The distance between the sensor and the inner wall of the protective sleeve 3 is 2mm to avoid contact and friction.

[0032] When in use, fix the mounting bracket to the side wall of the wastewater tank 6 with expansion bolts, adjust the angle so that the bottom tilt direction is consistent with the wastewater flow direction, connect the extension cable of the sensor and the secondary meter, and power on to test the signal transmission.

[0033] After industrial wastewater 7 enters wastewater tank 6, it forms a vortex under the action of the agitator. The wastewater enters the interior of the protective sleeve 3 through the drainage holes 12. Because the drainage holes 12 are evenly distributed, the impact force of the water flow is dispersed, preventing direct scouring of the sensor surface. Under the action of gravity and water pressure, the wastewater flows downward along the inner wall of the protective sleeve 3, is guided by the inclined pipe at the bottom end, and is accelerated to be discharged through the drain valve 8. The sensor monitors water quality parameters in real time, and the data is transmitted to the analyzer via the analyzer cable 2.

[0034] Field tests showed that the amount of sludge adhering to the sensor surface decreased by 80%, extending the cleaning cycle from 15 days to 2 months. The wear rate of the sensor coating decreased by 70%, extending the expected replacement cycle from 10 months to 2 years. The tilt angle design reduced sludge deposition at the bottom of the sleeve by 80%, and improved the flow stability of drain valve 8.

[0035] In different embodiments, for wastewater with different flow rates, the oblique cut pipe 9 with different end inclination angles can be replaced. When the wastewater flow rate is low, the inclination angle approaches 10°, and when the flow rate is high, the inclination angle approaches 30° to optimize drainage efficiency.

[0036] For wastewater with high impurities, the number of drainage holes can be increased to 20 holes in 5 columns × 4 holes, and the hole diameter can be reduced to Φ6mm to further disperse the impact of water flow.

[0037] This embodiment details the implementation of the present invention. Through the synergistic effect of the drainage hole 12 of the protective sleeve 3, the tilt angle, and the drain valve 8, the maintenance cost and service life of the sensor are significantly reduced, making it suitable for wastewater treatment systems in chemical, metallurgical, and other fields.
