Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5 , the present utility model provides a technical solution: a device for detecting heavy metal content in water, including a receiving circular plate 1 and a magnetic adsorption sheet 3. A connecting and sealing circular truncated cone 2 is provided at the center of the top surface of the receiving circular plate 1, and a magnetic adsorption sheet 3 is installed at the center of the connecting and sealing circular truncated cone 2. A transparent protective sleeve 4 is sleeved and installed above the receiving circular plate 1 and outside the connecting and sealing circular truncated cone 2, and an operating lever holder 5 is installed inside the transparent protective sleeve 4. An anti-slip strip 6 is provided on the outer surface of the top of the operating lever holder 5, and a storage hole groove 7 is provided inside the center of the operating lever holder 5. A discharge hole 8 is opened on the bottom border of the anti-slip strip 6. A magnetic block 9 is installed at the bottom end of the operating lever holder 5, and a sealing protective sleeve 10 is installed above the magnetic block 9, and the sealing protective sleeve 10 is sleeved and installed outside the bottom end of the operating lever holder 5.

[0024] The connecting and sealing circular truncated cone 2 and the receiving circular plate 1 are integrally structured, and the connection method between the receiving circular plate 1 and the transparent protective sleeve 4 through the connecting and sealing circular truncated cone 2 is snap-fit sealing, which is beneficial for assembling and sealing the transparent protective sleeve 4 with the receiving circular plate 1 through the connecting and sealing circular truncated cone 2 for subsequent water storage and preservation work.

[0025] The connection method between the magnetic adsorption sheet 3 and the connecting and sealing circular truncated cone 2 is inlaid and fixed, and the top surface of the magnetic adsorption sheet 3 is flush with the top surface of the connecting and sealing circular truncated cone 2. The connection method between the magnetic adsorption sheet 3 and the magnetic block 9 is magnetic connection, which can keep the magnetic adsorption sheet 3 and the connecting and sealing circular truncated cone 2 flat and avoid protrusion. At the same time, the magnetic connection between the magnetic adsorption sheet 3 and the magnetic block 9 facilitates the stable placement of the operating lever holder 5.

[0026] The operating lever frame 5 and the anti-slip strip 6 are integrated into a structure, and the anti-slip strips 6 are distributed at equal angles on the operating lever frame 5, and the top diameter of the operating lever frame 5 is larger than the bottom diameter of the operating lever frame 5, so that the operating lever frame 5 can be hand-held through the anti-slip strip 6 on the top of the operating lever frame 5, thereby improving the friction coefficient of the hand grip.

[0027] The discharge holes 8 are distributed at equal intervals and angles on the anti-slip strip 6, and the discharge holes 8 are connected to the internal space of the receiving hole groove 7. According to the connection between the discharge holes 8 and the receiving hole groove 7, the catalyst inside the receiving hole groove 7 can be discharged through the discharge holes 8 for subsequent reaction precipitation work.

[0028] The connection between the magnetic block 9 and the operating lever frame 5 is a snap-fit ​​seal, and the diameter of the magnetic block 9 is larger than the bottom diameter of the operating lever frame 5, which can seal the bottom outlet of the operating lever frame 5, making it convenient for the magnetic block 9 and the operating lever frame 5 to remain fixed. At the same time, the diameter of the magnetic block 9 is conducive to stable placement.

[0029] The sealing protective sleeve 10 is connected to the operating lever frame 5 by sliding sealing, and the height of the sealing protective sleeve 10 is greater than the distribution height between the discharge holes 8, and the sealing protective sleeve 10 is connected to the magnetic block 9 by magnetic connection, which allows the sealing protective sleeve 10 to slide and shift on the operating lever frame 5, making it convenient for the sealing protective sleeve 10 to seal the discharge hole 8 or start operation.

[0030] Working principle: According to Figures 1-5 First, the transparent protective cover 4 can be assembled and sealed with the connecting sealing truncated table 2 on the receiving circular plate 1, and then the water containing heavy metals can be poured into the transparent protective cover 4 for storage, and then the operating lever frame 5 can be hand-operated through the anti-slip strip 6 to release the catalyst inside the storage hole groove 7. The sealing protective cover 10 can be moved to slide upward at the bottom of the operating lever frame 5, so that the sealing protective cover 10 is magnetically separated from the magnetic block 9, and the discharge hole 8 at the bottom of the operating lever frame 5 is opened, which is conducive to the discharge of the catalyst inside the storage hole groove 7 through the discharge hole 8 into the transparent protective cover 4 and the water. A chemical reaction is carried out, and then precipitation work is carried out over time. According to the scale lines on the transparent protective cover 4, a rough judgment is made on the content of heavy metal substances precipitated inside. At the same time, after the subsequent cleaning is completed, the operating lever frame 5 needs to be placed and stored. The sealing protective cover 10 is simply pushed to slide and reset and magnetically adsorb the magnetic block 9 to seal the discharge hole 8. Then, the magnetic block 9 at the bottom of the operating lever frame 5 is magnetically adsorbed to the magnetic adsorption sheet 3 connected to the center of the sealing truncated table 2 to keep the placement stable. The above is the working process of the entire device, and the contents not described in detail in this manual belong to the existing technology known to professional and technical personnel in this field.

[0031] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model.
