Description

Technical Field

[0002] Drinking water disinfection can kill most pathogenic microorganisms in the water that are harmful to human health, reduce the risk of their occurrence to an acceptable safety range, and prevent waterborne diseases. Common disinfection methods include chlorine disinfection, chlorine dioxide disinfection, ozone disinfection, etc. Among them, chlorine disinfection is currently the most widely used disinfection method. Residual chlorine refers to the total amount of effective chlorine remaining in the water after the water reacts with the added chlorine when chlorine disinfection is used. my country's "Healthy Standards for Drinking Water" (GB5749-2022) stipulates that when chlorine disinfection is used, the contact time must be greater than 30 minutes, and the free chlorine in the water leaving the factory should not be less than 0.3 mg / L; the free chlorine at the end of the pipe network must not be less than 0.05 mg / L.

One end of the first pore passage is connected to the output end of the hot air blower. Furthermore, the number of drying branch pipes 9 corresponds to the number of second pore passages, and the second pore passage is connected to a drying branch pipe 9. The drying branch pipe 9 can introduce the airflow generated by the hot air blower into the bottom of the colorimetric tube 47 to dry the inner side wall of the colorimetric tube 47. A plurality of pores 91 can also be provided on the drying branch pipe 9, and the distribution of the pores 91 can be set according to actual needs. The pores 91 can increase the guiding direction and guiding position of the airflow to improve the drying efficiency of the inner side wall of the colorimetric tube 47.

[0085] It should be noted that the temperature of the hot air flow generated by the hot air blower can be set according to actual needs. For example, when drying is not required, a normal temperature air flow can be generated to dry the colorimetric tube 47. The specific setting can be based on actual needs.

[0086] In the above technical solution, the multifunctional colorimetric tube rack includes a base 1, a first connecting column 2, a second connecting column 3, a clip group 4, a cover plate 5, a brush group 6 and a driving unit. When in use, the base 1, the first connecting column 2, the second connecting column 3 and the clip group 4 constitute a structure for fixing the colorimetric tube 47. The colorimetric tube 47 is clamped in the first slot of the clip group 4. When pouring the liquid in the colorimetric tube 47, the colorimetric tube 47 can be directly inverted in batches by inverting the base 1, the first connecting column 2, the second connecting column 3 and the clip group 4. When cleaning is required, the cover plate 5 is covered on the first connecting column 2 and the second connecting column 3 so that the brushes in the brush group 6 correspond to the colorimetric tube 47 one by one, and then the colorimetric tube 47 is cleaned in batches by turning on the driving device. The entire technical solution can realize the clamping function of the colorimetric tube 47. When the colorimetric tube 47 needs to be dumped, the clamping piece group 4 can be used to fix the colorimetric tube 47 on the base 1 in batches, and the colorimetric tube 47 can be dumped in batches to improve the efficiency of waste liquid dumping. The setting of the brush group 6 on the cover plate 5 can realize the automatic batch cleaning of the colorimetric tube 47, which greatly simplifies the operation process of dumping, cleaning and inverting the colorimetric tube 47 and saves operation time.

[0087] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of the utility model, this does not limit the scope of patent protection of the utility model. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of the utility model using the contents recorded in the specification and drawings of the utility model, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of the utility model.
