Description

Technical Field

[0001] This utility model relates to the field of monitoring instrument technology, and in particular to a probe cleaning device for water analyzers. Background Technology

[0002] With the advancement of technology and the increasing awareness of environmental protection, the production and use of solar photovoltaic materials have entered a stage of rapid growth; as an important raw material for solar photovoltaic materials, the industrial production demand for polycrystalline silicon has also increased rapidly.

[0003] Polycrystalline silicon production primarily utilizes multi-wire cutting technology. During the cutting process, approximately 50% of the silicon material mixes into the cutting fluid, which is composed of polyethylene glycol cutting fluid and silicon carbide abrasive powder. This results in the micro-particle composition, particle size, and hardness of the cutting fluid failing to meet standards, leading to decreased cutting performance and preventing reuse. Therefore, the old cutting fluid must be continuously drained and replenished with new cutting fluid, generating a large amount of cutting wastewater. Direct discharge of this wastewater causes severe environmental pollution, necessitating the analysis of hazardous substances in the wastewater using water analysis instruments. Because the wastewater generated during polycrystalline silicon production contains many impurities, the probe of the water analysis instrument is in prolonged contact with the medium during measurement, making it prone to adhering to the probe surface and causing inaccurate measurements. Currently, this problem is addressed through manual cleaning. However, operators must come into contact with the wastewater during cleaning, which is not only labor-intensive but also carries the risk of harm from toxic substances in the wastewater. Furthermore, manual cleaning can damage equipment during operation, reducing its lifespan.

[0004] In response to this problem, this application proposes a water analyzer probe cleaning device. Utility Model Content

[0044] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0045] like Figures 1-3 As shown, this embodiment of the present invention provides a water analyzer probe cleaning device, comprising:

[0046] The protective sleeve 10 includes a tube body 101, a top cover 102 disposed on the top of the tube body 101, and a cleaning chamber 103 disposed at the bottom of the tube body 101.

[0047] Telescopic cylinder 20 is located above the protective sleeve 10. The cylinder shaft 201 of the telescopic cylinder 20 extends through the top cover 102 into the tube body 101.

[0048] The probe 30 is connected to the cylinder shaft 201 via a connecting rod;

[0049] The cleaning chamber 103 has a water inlet 1031 and an air inlet 1032 on its side. The water inlet 1031 is connected to a water pump 40 through a water inlet pipe, and the air inlet 1032 is connected to a first compressed air 50 through a first air inlet pipe.

[0050] The probe 30 can be stored inside the cleaning chamber 103.

[0051] Specifically, screw holes are provided on both sides of the tube body 101 and the top cover 102, and nuts 90 are provided on the screw holes for fixing the tube body 101 and the top cover 102.

[0052] In use, the probe 30 is retracted into the cleaning chamber 103 by the telescopic cylinder 20, and the water pump 40 is started to transport water from the wastewater tank into the cleaning chamber 103 through the water inlet pipe for water washing of the probe 30; then, the first compressed air 50 is transported into the cleaning chamber 103 through the first air inlet pipe for air washing of the probe 30, thereby cleaning away the medium adhering to the surface of the probe 30. This device combines water washing and air washing to replace manual cleaning, reducing the waste of human resources, avoiding the impact of harmful substances in wastewater on human health, and effectively preventing equipment damage caused by manual cleaning.

[0053] Furthermore, the air chamber of the telescopic cylinder 20 is connected to a second air inlet pipe, the other end of which is connected to a second compressed air 60, which is used to provide power for the reciprocating axial movement of the cylinder shaft 201 of the telescopic cylinder 20.

[0054] Specifically, the water inlet pipe, the first air inlet pipe, and the second air inlet pipe are all flexible hoses to facilitate the flexible use of the device.

[0055] In addition, the water analyzer probe cleaning device also includes:

[0056] The solenoid valve 70 includes a first solenoid valve 701, a second solenoid valve 702 and a third solenoid valve 703. The first solenoid valve 701 is located on the first air inlet pipe, the second solenoid valve 702 is located on the water inlet pipe, and the third solenoid valve 703 is located on the second air inlet pipe.

[0057] The controller 80 is electrically connected to the water pump 40, the first solenoid valve 701, the second solenoid valve 702, and the third solenoid valve 703, respectively.

[0058] The automatic cleaning of the water analyzer probe cleaning device can be achieved through solenoid valve 70 and controller 80. During use, controller 80 controls the opening of the third solenoid valve 703, allowing the second compressed air 60 to enter the air chamber of the telescopic cylinder 20. This causes the cylinder shaft 201 to drive the probe 30 axially, retracting it into the cleaning chamber 103. Controller 80 then controls the opening of the second solenoid valve 702 and starts the water pump 40 to achieve water washing of the probe 30. Controller 80 also controls the opening of the first solenoid valve 701, delivering the first compressed air 50 into the cleaning chamber 103 to achieve air washing of the probe 30. The entire process is orderly, efficient, and highly automated, avoiding waste of human resources.

[0059] To facilitate the cleaning of impurities adhering to the surface of the probe 30, a gap is left between the probe 30 and the inner wall of the cleaning chamber 103.

[0060] Since the bottom of the cleaning chamber 103 has an opening for the probe 30 to move, and the top of the cleaning chamber 103 is connected to the tube 101, in order to ensure that the impurities attached to the surface of the probe 30 can be cleaned away, the top and bottom of the outer periphery of the probe 30 are provided with annular protrusions 301. The annular protrusions 301 are in contact with the inner wall of the cleaning chamber 103, thereby preventing water or air from flowing out of the cleaning chamber 103.

[0061] Specifically, the first compressed air 50 is instrument air. Instrument air has good stability, purity and safety, and is easy to store. When using it, its pressure range needs to be controlled to prevent excessive pressure from affecting the use of the equipment or insufficient pressure from causing inadequate cleaning. In this embodiment, the pressure of the instrument air is 0.4 MPa, which is optimal.

[0062] To reduce the space occupied, the diameter of the pipe body 101 is smaller than the diameter of the cleaning chamber 103, and this further prevents wastewater from flowing into the pipe body 101.

[0063] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
