Pressure relief device for ultrafiltration canister

Abstract

This utility model belongs to the field of ultrafiltration tanks, specifically relating to a pressure relief and protection device for an ultrafiltration tank. It includes a tank body, with a controller fixedly installed at the front end. An inlet pipe is fixedly connected to the top of the tank body, and a drain pipe is fixedly connected to the bottom. A guide port is fixedly connected to the lower end of the drain pipe, communicating with the inlet pipe. A collection tank is fixedly connected to the bottom of the guide port. This utility model, through the design of the tank body, enables ultrafiltration of liquids. Liquid is transported into the tank body through the inlet pipe. During liquid input, when the liquid pressure is too high, the liquid will press down on a baffle, causing the baffle to move the sealing ring downwards. When the sealing ring separates from the inner wall of the guide port, the liquid flows into the collection tank through the guide port, thus relieving pressure inside the tank and preventing damage to the ultrafiltration membrane due to excessive liquid pressure.

Description

Technical Field

[0001] This utility model relates to the field of ultrafiltration tank technology, and in particular to a pressure relief protection device for ultrafiltration tanks. Background Technology

[0002] Ultrafiltration tanks are widely used in the water treatment field, mainly for water purification in households, communities, or industrial production. They can remove suspended solids, colloids, microorganisms, and other impurities in drinking water preparation, industrial circulating water filtration, wastewater pretreatment, and greywater reuse, providing clean water sources for domestic use, standard-compliant process water for industrial production, or creating favorable conditions for subsequent advanced treatment processes. They are important equipment for ensuring water quality safety and stable operation of industrial production.

[0003] Utility model patent CN219815858U discloses a tank-type ultrafiltration device, including a housing. An upper cover is fixedly connected to the upper end of the housing, and a lower cover is fixedly connected to the lower end of the housing. An ultrafiltration mechanism, a blower mechanism, and a cleaning mechanism are all located inside the housing. A controller is fixedly connected to the outer side of the housing. An upper partition plate is fixedly connected to the upper end of the housing, and a lower partition plate is fixedly connected to the lower end of the housing. A coarse filtration mechanism is located at the upper end of the upper partition plate, and a water pump is fixedly installed at the upper end of the upper partition plate. By adding non-woven fabric, brushes, and blower pipes inside the ultrafiltration device, the non-woven fabric can pre-filter the water, removing large particles and reducing wear on the ultrafiltration membrane during the ultrafiltration process. The blower pipe and brushes can clean residues, ensuring the efficiency of the ultrafiltration membrane, making it quite practical.

[0004] In the aforementioned existing technology, the ultrafiltration tank has poor protective performance during use and is not convenient for pressure relief. When the water pressure is too high, it can easily damage the ultrafiltration membrane, and when the gas pressure is too high, it can cause safety issues. Therefore, the existing technology needs to be improved. Utility Model Content

[0013] Compared with related technologies, the pressure relief protection device for the ultrafiltration tank provided by this utility model has the following beneficial effects:

[0014] This utility model provides a pressure relief and protection device for an ultrafiltration filter tank. By designing the function of the tank, ultrafiltration of liquid can be performed. Liquid can be transported into the tank through the inlet pipe. During the liquid input process, when the liquid pressure is too high, the liquid will press down on the baffle, and the baffle will drive the sealing ring to move down. When the sealing ring separates from the inner wall of the guide port, the liquid will flow into the inside of the collection tank through the guide port. This can relieve the pressure inside the tank and prevent the ultrafiltration membrane from being damaged due to excessive liquid pressure.

[0015] This utility model provides a pressure relief and protection device for an ultrafiltration filter canister. By designing a fixed base that is connected to the canister, when the internal gas pressure of the canister is high, the gas will push the plug to the right, and the gas will then enter the interior of the fixed base and be discharged through the exhaust port. Under the action of the filter element, the gas can be filtered and purified to prevent odor leakage. This also allows for pressure relief of the gas inside the canister, preventing excessive internal gas pressure and improving the protection effect of the ultrafiltration canister. Furthermore, the connecting base and the fixed base are easy to separate, facilitating filter element replacement. Attached Figure Description

A first spring 84 is provided on the outer side of the support rod 83.

A limit ring 87 is fixedly connected to the bottom of the support rod 83. By designing the pressure relief mechanism 8, pressure relief protection can be provided when the water pressure is too high.

[0024] Please see Figure 1 , Figure 2 , Figure 4 The exhaust mechanism 9 includes a plug 91, which is slidably fitted inside the fixed base 11. A sealing sleeve 92 is fixedly fitted outside the plug 91, and the sealing sleeve 92 is slidably connected to the fixed base 11. By designing the sealing sleeve 92, the connection between the plug 91 and the fixed base 11 can be sealed.

[0025] Working principle: During use, the liquid can be ultrafiltered through the action of the tank 1. The specific working process has been disclosed in the utility model patent with patent authorization announcement number CN219815858U, and will not be repeated here. When liquid is introduced through the liquid inlet pipe 3, if the liquid pressure is too high, the liquid will push the baffle 82 downward. The baffle 82 will drive the sealing ring 81 downward. At the same time, the baffle 82 will drive the support rod 83 to slide along the support ring 85. The baffle 82 will squeeze the first spring 84, which can separate the sealing ring 81 from the inner wall of the guide port 5. At this time, the liquid will enter through the gap between the sealing ring 81 and the inner wall of the guide port 5 and flow into the collection tank 6 for collection. This can relieve the pressure inside the tank 1 and prevent the ultrafiltration membrane from being damaged due to excessive liquid pressure.

[0026] When the internal pressure of the tank 1 is too high, the gas will push the plug 91 to the right. The plug 91 will move the sealing sleeve 92. At the same time, the plug 91 will move the filter element 93, the connecting rod 94 and the slider 95. The slider 95 will squeeze the second spring 97, which will separate the plug 91 from the fixed seat 11. At this time, the gas will enter the fixed seat 11. The filter element 93 can filter and purify the gas to avoid odor pollution. Finally, the gas will be discharged through the exhaust port 98, which will avoid the problem of excessive internal pressure of the tank 1 and improve the protection effect of the ultrafiltration tank. In addition, the connecting seat 96 and the fixed seat 11 can be easily separated, which is convenient for replacing the filter element 93.
