Description

Technical Field

[0001] The utility model relates to the technical field of respirators, in particular to a water storage tank respirator with a sterilization function. Background Art

[0002] A respirator is a common component on a water storage tank. It effectively blocks external particulate matter and microorganisms through a filter element, thereby reducing the impact on the water quality in the tank. A respirator with an electrically heated jacket or steam tracing and a self-draining port can effectively prevent the occurrence of a "collapsed tank" and can effectively reduce the probability of bacteria contamination of the respirator on the injection water tank. To ensure the use effect of the respirator, the filter element needs to be disinfected and sterilized regularly. When disinfecting and sterilizing the filter element, due to the structural design of the respirator, the filter element can only be removed and placed in a sterilization cabinet for disinfection and sterilization treatment. Contamination may occur during the disassembly and transportation process, and it also affects work efficiency.

[0003] In the prior art, for the Chinese utility model patent with the application number CN202221412149.7 and the name of an on-line sterilization device for a storage tank respirator, it uses secondary steam to flow into the respirator for sterilization, preventing the growth of bacteria in the respirator and facilitating the reasonable use of the respirator. When sterilizing, the respirator does not need to be removed, which can avoid the contamination caused by the exposure of injection water to the air. Although the technical solution also mentions discharging the condensed water generated during the sterilization of the respirator, it does not elaborate on the means of effectively collecting and discharging the condensed water in the respirator. According to the description of the technical solution, a part of the condensed water may remain in the respirator or the pipeline between the respirator and the injection water storage tank, and may even flow back into the injection water storage tank, causing secondary pollution. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a water storage tank respirator with a sterilization function to solve the problem that in the prior art, a part of the condensed water may remain in the respirator or the pipeline, and may even flow back into the injection water storage tank, causing secondary pollution.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A water storage tank respirator with a sterilization function includes a housing, a base, a filter element, a hoop, an exhaust valve, a drain valve, and a collector.

[0024] Example 1:

[0025] As shown in this embodiment Figure 1 shown, a water storage tank breather with a sterilization function includes a housing 1, a base 2, a filter element 3, a hoop 4, an exhaust valve 5, a drain valve 6, and a collector 7. The housing 1 is connected to the base 2 through the hoop 4. The filter element 3 is installed in the cavity between the housing 1 and the base 2. The exhaust valve 5 communicates with the top of the housing 1. The drain valve 6 communicates with a water collecting tank 8 inside the base 2. The collector 7 is installed in the base 2, and the outer edge of the collector 7 is arranged opposite to the water collecting tank 8. The base 2 is communicated with an external steam source through a steam pipe 9.

[0026] When the external steam source (steam generator or steam boiler) supplies steam to the base 2 through the steam pipe 9, the steam moves upward and diffuses in the cavity between the housing 1 and the base 2. The high-temperature steam sterilizes the filter element 3. At the same time, the steam will also be cooled to generate condensed water and fall. After being collected and guided by the collector 7, it enters the water collecting tank 8. The collector 7 can be a water receiving tray, and the condensed water is obliquely flowed into the water collecting tank 8 and discharged through the drain valve 6. The exhaust valve 5 can discharge the excess water vapor in the breather.

[0027] Preferably, a one-way valve 10 is provided between the base 2 and the water storage tank.

[0028] The one-way valve 10 can play a one-way blocking role in the pipeline between the base 2 and the water storage tank, preventing steam from entering the water storage tank, and at the same time not affecting the breather to balance the air pressure in the water storage tank.

[0029] Preferably, a thermometer 11 is provided at the top of the housing 1.

[0030] The thermometer 11 can help the staff know the temperature inside the breather, and then grasp the sterilization situation.

[0031] Preferably, a pressure gauge 12 is provided at the top of the housing 1.

[0032] The pressure gauge 12 can help the staff know the pressure inside the breather, and then grasp the sterilization situation.

[0033] Embodiment 2:

[0034] Based on the above embodiment, as shown in this embodiment Figure 2 and Figure 3 shown, the collector 7 includes a support rod 13, a conical cover 14, and a plurality of conical rings 15 with different diameters and concentrically arranged. The conical rings 15 are distributed from large to small in diameter and from bottom to top. The conical cover 14 is located at the top of the conical rings 15. The conical cover 14 and the conical rings 15 are both connected to the base 2 through the support rod 13.

[0035] A passage for the convenient flow of steam is left between the conical cover 14 and multiple conical rings 15 with different diameters and concentric settings. Moreover, the center of the conical ring 15 and the conical ring 15 act together to diverge the steam, promoting better contact between the steam and the filter element 3. Additionally, the condensed water falling from the filter element 3 can be collected and flow obliquely into the water collecting tank 8, and is discharged uniformly through the drain valve 6.

[0036] Preferably, the outer edge of the upper conical ring 15 and the inner edge of the lower conical ring 15 overlap each other.

[0037] It can fully ensure that the water droplets on the outer edge of the upper conical ring 15 fall on the lower conical ring 15, preventing them from falling into the water storage tank and the pipelines thereon, thus avoiding secondary pollution.

[0038] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
