Technical Field

The utility model relates to the technical field of drinking water filter elements, in particular to a drinking water filter element flushing life testing device.

Background Art

Drinking water filter is a key component for purifying water. It can effectively filter impurities, harmful substances, bacteria and viruses in water to ensure that we drink safe and healthy drinking water. The existing drinking water filter flushing life test mainly flushes the filter continuously with water. After a certain period of time, the filtered water is extracted for testing to infer whether the filter still has a good filtering effect after a long period of flushing, that is, whether the service life of the filter is reduced.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1, 2, 3 and 4. The utility model provides a technical solution: a drinking water filter element flushing life test device, comprising a test box 1, a water inlet opened at the top of the test box 1, and a plurality of filter element samples 2 arranged inside the test box 1;

A plurality of test chambers 3 are provided inside the test box 1, and a water discharge assembly 301 is provided inside each test chamber 3. A connecting pipe 302 is connected and fixedly connected inside each test chamber 3, and a detection box 303 is connected and fixedly connected at the bottom end of each connecting pipe 302. A water quality detector 304 is provided on each detection box 303. By using the filter element sample 2 and the test chamber 3 in cooperation with each other, the operator only needs to pour in a water body with many impurities, and gradually remove larger particles, suspended matter and some soluble substances by step-by-step filtration, so that the filter element sample 2 can detect water bodies with different impurity contents. After the filter element is gradually contaminated, the filtering effect of the filter element will decrease. At this time, the water quality change inside the detection box 303 can be detected by the water quality detector 304, so as to evaluate the service life of the filter element sample 2 after being flushed with different water qualities.

Preferably, each test chamber 3 is connected to a frame 4, and each filter element sample 2 is slidably connected to the frame 4. Under the action of the frame 4, the filter element sample 2 can be lifted, so that the water is filtered through the filter element sample 2 and gathered in the test chamber 3, avoiding the filtered water from being still stored in the filter element sample 2.

Preferably, each detection box 303 is connected and fixedly connected to a drain pipe 305 , and each drain pipe 305 is provided with a valve. By opening the valve inside the drain pipe 305 , the water inside the detection box 303 can be discharged.

Preferably, the water discharge assembly 301 includes a water discharge port and a control valve;

Each test chamber 3 is provided with a water outlet, and each water outlet is provided with a control valve.

Preferably, a fixing plate 401 is attached to the outside of each filter element sample 2, and a locking mechanism is provided on the outside of each fixing plate 401. The filter element sample 2 is limited inside the test chamber 3 by the fixing plate 401, thereby reducing the entry of foreign matter into the test chamber 3 and affecting the filtration of the filter element sample 2. The outer wall of each fixing plate 401 is connected to an elastic plate 404. Under the action of the elastic plate 404, the water filtered by the filter element sample 2 can be reduced from flowing down the inner wall of the fixing plate 401, thereby reducing the outflow of water through the gap between the fixing plate 401 and the outlet of the test chamber 3.

Preferably, the engaging mechanism includes a spring 402 and a clamping plate 403;

The upper and lower ends of the outer wall of each fixing plate 401 are connected with a spring 402, and the outer wall of each spring 402 is clamped with a clamping plate 403, and each clamping plate 403 is connected to the outer wall of the test box 1. By providing a clamping mechanism, the fixing plate 401 can stably squeeze the filter element sample 2 into the test chamber 3.

Preferably, each fixing plate 401 is connected to an observation window 405 , and the observation window 405 is a transparent acrylic plate. The observation window 405 can facilitate an operator to quickly understand the filtering condition of the filter element sample 2 .

Working principle: During laboratory testing, sewage is used instead of drinking water to achieve a rapid test of the service life of the filter element. First, water is injected into the water inlet at the top of the test box 1, and the water is filtered through the filter element sample 2. The filtered water enters the test box 303 through the connecting pipe 302, and the water inside the test box 303 is tested by the water quality detector 304 to compare the water quality before and after. When the top filter element sample 2 completes filtering the water, the control valve inside the water discharge component 301 is opened to allow the water to enter the next level filter element sample 2 for filtration. The above steps are repeated continuously, so that the same type of filter element sample 2 can filter water with different impurity contents. By filtering, the service life of the filter element sample 2 after being flushed with water with different impurity contents can be effectively detected. When the water inside the detection box 303 needs to be discharged, the water inside the detection box 303 can be discharged by opening the valve inside the drain pipe 305. By using the filter element sample 2 and the test chamber 3 in coordination with each other, the operator only needs to pour in a water with a lot of impurities, and gradually remove the larger particles, suspended matter and some soluble substances by filtering step by step, so that the filter element sample 2 can detect water with different impurity contents. After the filter element is gradually contaminated, the filtering effect of the filter element will decrease. At this time, the flushing life of the filter element sample 2 can be evaluated according to the change in the outlet water quality.

By observing the observation window 405, the filtering condition of the filter element sample 2 can be understood. When the filter element sample 2 needs to be taken out, the operator pulls the fixing plate 401 to deform the spring 402 inside the clamping plate 403, and the elastic plate 404 moves in contact with the outlet of the test chamber 3, thereby deforming the elastic plate 404 until the spring 402 is separated from the clamping plate 403, and the fixing plate 401 is separated from the outlet of the test chamber 3, so that the fixing plate 401 no longer blocks the filter element sample 2, and the operator can then take the filter element sample 2 out of the frame 4.

The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
