Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cleaning equipment technology, and in particular to a pH meter all-round cleaning device. Background Technology
[0002] In wastewater treatment processes and many production processes, certain substances added or generated are sticky and easily adhere to pH electrodes, thus isolating the pH electrode from the process medium, causing pH value distortion and reducing the lifespan of the pH meter. To reduce this phenomenon and ensure continuous and stable operation of the pH meter, the pH electrode must be cleaned regularly.
[0003] The following are existing methods for cleaning pH meters:
[0004] Based on experience, pH meters are periodically removed for manual cleaning; however, when the measured medium contains a large amount of impurities, manual cleaning is labor-intensive and time-consuming, and can easily damage the pH electrode. Therefore, automatic cleaning is generally used. Common pH meter cleaning methods include ultrasonic cleaning and jet cleaning.
[0005] Ultrasonic cleaning involves installing a device that generates ultrasonic waves near the pH meter. These waves automatically clean the electrodes of the online pH meter, and the intensity of the waves can be adjusted by changing the oscillation frequency. However, this cleaning method has drawbacks such as high cost and incomplete cleaning.
[0006] Solution spray cleaning involves installing cleaning nozzles near the pH meter. Depending on the cleaning requirements, the nozzles periodically spray water or other solutions (such as a 1% dilute nitric acid solution or a dilute hydrochloric acid solution). Existing spray structures typically use nozzles arranged in a circular pattern, and the pH meter is cleaned while stationary. This easily creates cleaning dead zones and results in poor cleaning power, leading to incomplete cleaning. Utility Model Content

[0013] In the aforementioned pH meter omnidirectional cleaning device, the translation component includes a servo motor, the shaft of which is connected to a lead screw, a guide rail is arranged parallel to the side of the lead screw, a nut is fitted onto the lead screw to form a threaded engagement connection, a slider is fixed on the nut, the slider engages with the guide rail to form a sliding connection, a long strip housing is provided around the lead screw and the guide rail, both ends of the lead screw are hinged to the long strip housing through hinge seats, the guide rail is fixed to the inner wall of the long strip housing, a long strip through groove is provided on the long strip housing, a connecting rod is provided on the slider extending out of the long strip through groove, and the outer end of the connecting rod is fixed to a bracket.

[0015] In the above-mentioned pH meter omnidirectional cleaning device, the lifting assembly includes a lifting cylinder fixed on the bracket, the lifting cylinder extending a lifting rod downwards, and the bottom of the lifting rod being fixedly connected to a flat plate.

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0030] Example 1
[0031] like Figures 1 to 3 As shown, this pH meter omnidirectional cleaning device includes a drive mechanism located above and a cleaning mechanism located below. The drive mechanism includes a translation component, which drives a lifting component, which in turn drives a rotating component. The pH meter 8 is mounted on the rotating component. The cleaning mechanism includes a cleaning tank 9, which contains a spiral nozzle 10. The spiral nozzle 10 forms a spray space on its inner circumference. Several nozzles 11 are arranged on the spiral nozzle 10 toward the spray space. The pH meter 8 descends and extends into the spray space.
[0032] like Figure 1 and 2 As shown, preferably, the translation assembly includes a horizontal cylinder 1, with a telescopic shaft of the horizontal cylinder 1 fixedly connected to a telescopic rod. A long strip housing 2 covers the outer periphery of the telescopic rod, and a long strip groove is formed on the long strip housing 2. A connecting rod extending out of the long strip groove is provided on the telescopic rod, and the connecting rod forms a guide sliding connection along the long strip groove. The outer end of the connecting rod is fixedly connected to a bracket 3. The horizontal cylinder 1 drives the telescopic rod to extend or retract, simultaneously driving the connecting rod to slide back and forth along the long strip groove, and simultaneously driving the bracket 3 to reciprocate and translate, thereby moving the pH meter 8 to a horizontal position. The aforementioned method of the horizontal cylinder 1 driving the telescopic rod to extend and retract is prior art, as is the reciprocating sliding of the connecting rod along the long strip groove.
[0033] Preferably, the lifting assembly includes a lifting cylinder 4 fixedly mounted on the bracket 3, with a lifting rod extending downwards from the lifting cylinder 4, and a flat plate 5 fixedly connected to the bottom of the lifting rod. Activating the lifting cylinder 4 drives the lifting rod to rise or fall, thereby causing the pH meter 8 to rise out of the spray cleaning space or fall into the spray cleaning space via the flat plate 5. The lifting cylinder 4 driving the lifting rod to rise or fall is existing technology.
[0034] Preferably, the rotating assembly includes a rotary motor 6 fixed to the bottom surface of the flat plate 5, with a rotating shaft extending downwards from the rotary motor 6. The bottom end of the rotating shaft is fixedly connected to the pH meter 8 via a base plate 7. Starting the rotary motor 6 drives the rotating shaft to rotate in both directions, simultaneously causing the base plate 7 and the pH meter 8 to rotate in both directions, thus achieving continuous directional movement of the pH meter 8 during the cleaning process. The rotary motor 6 driving the rotating shaft to rotate in both directions is existing technology.
[0035] like Figure 3 As shown, preferably, the spiral nozzle 10 is formed by bending a circular tube around a spiral trajectory. Divided according to the height range of the spiral trajectory, the spiral nozzle 10 has an upper coil 10a, a middle coil 10b, and a lower coil 10c. The spiral nozzle 10 is connected to a liquid supply device via a water inlet pipe. In the spiral nozzle 10, the upper coil 10a is formed by one revolution along the spiral trajectory from the starting end, the middle coil 10b is formed by another revolution, and finally the lower coil 10c is formed by the last revolution. The starting end of the upper coil 10a and the last end of the lower coil 10c form a circumference.
[0036] Preferably, the nozzles 11 arranged in the upper ring 10a are tilted downwards at an angle ranging from -15° to -30°; the nozzles 11 arranged in the middle ring 10b are horizontally positioned; and the nozzles 11 arranged in the lower ring 10c are tilted upwards at an angle ranging from 15° to 30°. The design of the upper nozzles 11 tilting downwards, the middle nozzles 11 spraying horizontally, and the lower nozzles 11 tilting upwards concentrates the spray impact force in the central area, thereby enhancing the spray intensity, but reducing the spray range. This design is suitable for cleaning thicker, more stubborn dirt on the pH meter 8.
[0037] Preferably, the nozzle 11 is a conical tube, with the large-diameter opening of the conical tube connected to the inner wall of the spiral nozzle 10, and the small-diameter opening of the conical tube facing the spraying space. Several circular holes are opened on the inner wall of the spiral nozzle 10, and the large-diameter opening of the conical tube is welded to the circular holes.
[0038] Preferably, a drain valve is installed at the bottom of the cleaning tank 9, and the drain valve is connected to a drain pipe. When the liquid accumulated in the cleaning tank 9 reaches a certain height, in order to ensure the subsequent cleaning effect and to prevent the cleaning liquid from overflowing, the drain valve is opened and the waste liquid is discharged through the drain pipe.
[0039] Example 2
[0040] This embodiment is basically the same as Embodiment 1, except that:
[0041] Preferably, the nozzles 11 arranged in the upper ring 10a are horizontally positioned; the nozzles 11 arranged in the middle ring 10b are horizontally positioned; and the nozzles 11 arranged in the lower ring 10c are horizontally positioned. The upper, middle, and lower nozzles 11 are all designed to spray horizontally, thereby expanding the cleaning range, but the spray intensity is relatively reduced, making it suitable for cleaning smaller, easier-to-clean contaminants on the pH meter 8.
[0042] Example 3
[0043] This embodiment is basically the same as Embodiment 1, except that:
[0044] Preferably, the translation component includes a servo motor, the shaft of the servo motor is connected to a lead screw, a guide rail is arranged parallel to the side of the lead screw, a nut is sleeved on the lead screw to form a threaded engagement connection, a slider is fixed on the nut, the slider is engaged with the guide rail to form a sliding connection, a long strip housing 2 is covered on the outer periphery of the lead screw and the guide rail, the two ends of the lead screw are hinged to the long strip housing 2 through hinge seats, the guide rail is fixed to the inner wall of the long strip housing 2, a long strip through groove is opened on the long strip housing 2, a connecting rod is provided on the slider extending out of the long strip through groove, and the outer end of the connecting rod is fixed to a bracket 3.
[0045] The servo motor drives the lead screw to rotate forward and backward, which in turn drives the nut and slider to reciprocate along the guide rail through threaded engagement. This further drives the bracket 3 to reciprocate, thus achieving the horizontal position of the moving pH meter 8. The aforementioned structure of the servo motor, lead screw, nut, guide rail, slider, and bracket 3 constitutes a servo drive system. Servo drive systems are existing technologies and are commonly used in mechanical automation applications; therefore, detailed internal structure diagrams are not provided here.
[0046] The working principle of this pH meter's all-around cleaning device is as follows:
[0047] 1. Activate the translation component to move the pH meter 8 above the cleaning tank 9 and directly above the spray space;
[0048] 2. Activate the lifting assembly to drive the pH meter 8 to descend, so that the pH meter 8 is fully inserted into the spray space inside the spiral nozzle 10.
[0049] 3. Start the liquid supply equipment to inject cleaning fluid into the spiral nozzle 10. Under pressure, the cleaning fluid is sprayed out from several nozzles 11.
[0050] 4. Simultaneously activate the lifting and rotating components to make the pH meter 8 perform a compound motion of reciprocating lifting and rotation within a certain height range. Combined with the 360° spray cleaning from the spiral nozzle 10, a high-intensity, all-round thorough cleaning of the pH meter 8 is achieved.
