DETAILED DESCRIPTION

[0040] The present application is described in detail below with reference to embodiments, but the present application is not limited to these embodiments.

[0041] According to the attached Figure 1-2 The porous glass plate absorption tube cleaning device shown comprises: an air storage chamber 5 and a liquid storage chamber 8 independently arranged along the horizontal direction, and a mixing chamber 13 located at the top of the air storage chamber 5 and the liquid storage chamber 8;

[0042] The input end of the gas storage chamber 5 is connected to the gas source, the output end of the gas storage chamber 5 is connected to the input end of the mixing chamber 13, and the input end of the gas storage chamber 5 is provided with a gas source on-off device;

[0043] The gas source on-off device is used to realize whether to input gas into the mixing chamber 13, and prevent the medium in the mixing chamber 13 from flowing back into the gas storage chamber 5;

[0044] The input end of the liquid storage chamber 8 is connected to the cleaning liquid, the output end of the liquid storage chamber 8 is connected to the input end of the mixing chamber 13, and a one-way valve 10 is provided at the output end of the liquid storage chamber 8; wherein the one-way valve 10 opens upward (i.e., toward one side of the second channel 11);

[0045] The one-way valve 10 is used to allow the cleaning liquid to enter the mixing chamber 13 and prevent the medium in the mixing chamber 13 from flowing back into the liquid storage chamber 8;

[0046] The output end of the mixing chamber 13 is connected to the porous glass plate absorption tube, and a bubble ball is arranged in the mixing chamber 13 .

[0047] Furthermore, a first channel 12 is provided between the input end of the gas storage chamber 5 and the mixing chamber 13;

[0048] A second channel 11 is provided between the output end of the liquid storage chamber 8 and the mixing chamber 13;

[0049] The first channel 12 and the second channel 11 are arranged opposite to each other, and the input ends of the first channel 12 and the second channel 11 are connected to the air storage chamber 5 and the liquid storage chamber 8 respectively, and the output ends of the first channel 12 and the second channel 11 are arranged opposite to each other and are connected to the input ends of the mixing chamber 13 respectively.

[0050] Furthermore, the first channel 12 and the second channel 11 are respectively in the shape of arcs with openings facing each other, and the cross-sections of the first channel 12 and the second channel 11 can be either circular or square, wherein the diameter of the bubble ball 14 is larger than the cross-sectional dimensions of the first channel 12 and the second channel 11, and the bubble ball 14 is a lightweight sphere made of foam or other materials.

[0051] Furthermore, the cross-sectional dimensions of the first channel 12 and the second channel 11 are respectively smaller than the cross-sectional dimensions of the air storage chamber 5 and the liquid storage chamber 8 .

[0052] Since the cross-sectional dimensions of the first channel 12 and the second channel 11 are respectively smaller than the cross-sectional dimensions of the gas storage chamber 5 and the liquid storage chamber 8, when the gas flows into the first channel 12 from the gas storage chamber 5 and the cleaning liquid enters the second channel 11 from the water storage chamber, the cleaning liquid and the gas are pressurized respectively to achieve contact between the gas and the cleaning liquid in the mixing chamber 13, to mix the gas and water, and to achieve bubbling. The bubbling ball 14 in the mixing chamber 13 is flipped or rolled due to the impact of the liquid and gas entering the mixing chamber 13, so as to stir the gas-liquid mixed medium in the mixing chamber 13 and generate bubbles, making the foam richer.

[0053] Furthermore, a delivery pipe 15 is provided at the output end of the mixing chamber 13;

[0054] The input end of the delivery pipe 15 is connected to the output end of the mixing chamber 13, and the output end of the delivery pipe 15 is connected to the porous glass plate absorption tube. The mixed foam is input into the porous glass plate absorption tube through the delivery pipe 15 to clean the porous glass plate absorption tube.

[0055] Furthermore, the cross section of the delivery pipe 15 is smaller than the cross section of the mixing chamber 13, so as to pressurize the cleaning medium delivered to the porous glass plate absorption tube to increase the flow rate of the cleaning medium.

[0056] Furthermore, the gas storage chamber includes a gas storage chamber 1, a pressurizing channel 2 and a gas transmission channel arranged from bottom to top;

[0057] The input end of the gas storage bin 1 is arranged downward and connected to a gas source;

[0058] The output end of the gas storage tank 1 is connected to the input end of the pressurizing channel 2;

[0059] The cross section of the pressurizing channel 2 is smaller than the cross section of the gas storage chamber 1, and the output end of the pressurizing channel 2 faces the gas source on-off device;

[0060] The gas source on-off device is located in the gas transmission channel;

[0061] The gas delivery channel is connected to the input ends of the pressurizing channel 2 and the first channel 12 respectively.

[0062] Furthermore, a first limit portion 4 is provided on the inner wall of the input end of the gas transmission channel, and a second limit portion 7 is provided on the inner wall of the output end of the gas transmission channel;

[0063] The first limiting portion 4 and the second limiting portion 7 are respectively annular structures, and are respectively fixedly connected to the inner wall of the input end of the gas transmission channel and the output end of the gas transmission channel;

[0064] The gas source on-off device is located between the first limiting portion 4 and the second limiting portion 7, and the gas source on-off device includes a spring 6 and a blocking plate 3;

[0065] The spring 6 is vertically arranged, one end of the spring 6 is connected to the bottom of the second limiting portion 7, and the other end of the spring 6 is connected to the blocking plate 3. The maximum cross-section of the blocking plate 3 is larger than the inner circle size of the first limiting portion 4. In one embodiment of the present application, the blocking plate 3 is a rubber plate.

[0066] In the present application, the gas enters the pressurized channel 2 from the gas storage bin 1 and is further pressurized, so as to push the plugging plate 3 upwards. The plugging plate 3 moves upwards, pushing the spring 6 to compress. At this time, an airflow gap is formed between the plugging plate 3 and the gas transmission channel, and the gas enters the gas transmission channel from the pressurized channel 2 through the airflow gap. When the gas storage bin 1 is no longer passing gas, the compressed spring 6 rebounds, and at this time the plugging plate 3 abuts against the top of the first limit, preventing the medium in the mixing chamber 13 from entering the gas storage bin 1 and flowing out of the gas storage bin 1, thereby realizing the function of unidirectional gas flow.

[0067] The blocking plate 3 is in an inverted triangle shape as a whole, and the side of the blocking plate 3 facing away from the spring 6 faces the first limiting portion 4 .

[0068] The inner circle size of the second limiting portion 7 is larger than the cross-sectional size of the first channel 12 .

[0069] Furthermore, a limit rod 9 is provided inside the spring 6;

[0070] The limiting rod 9 is inserted into the spring 6 , and one end of the limiting rod 9 facing the blocking plate 3 is connected to the blocking plate 3 . The length of the limiting rod 9 is smaller than the distance between the first limiting portion 4 and the second limiting portion 7 .

[0071] When the porous glass plate absorption tube is cleaned using this device, it goes through three stages:

[0072] In the first stage, cleaning is performed by means of a cleaning fluid;

[0073] First, a cleaning medium (here, the cleaning medium is a cleaning liquid mixed with a detergent and water) is introduced into the liquid storage chamber 8, and gas is introduced into the gas storage chamber 5;

[0074] The cleaning liquid of detergent and water enters the liquid storage chamber 8, pushes the one-way valve 10 upward, and enters the second channel 11 for pressurization; the gas entering the gas storage chamber 5 enters the pressurization channel 2 and is first pressurized, and the pressurized airflow pushes the blocking plate 3 upward. At this time, a gap appears between the blocking plate 3 and the inner wall of the gas transmission channel, and the airflow enters the gas transmission channel, and then enters the first channel 12 for pressurization again. The pressurized airflow and the pressurized cleaning liquid flow into the mixing chamber 13 respectively, and the bubbles after mixing in the mixing chamber 13 are mixed evenly by the bubbling ball 14 in the mixing chamber 13, making the generated foam richer, and then the foamy cleaning liquid is transported to the porous glass plate absorption tube through the delivery pipe 15. Since the foam adheres to the surface of the inner wall of the porous glass plate absorption tube to be cleaned, the foam can loosen and remove the dirt and debris on the surface, making it easier to remove, thereby achieving the cleaning effect.

[0075] In the second stage, clean water is passed into the liquid storage chamber 8, and it is not necessary to pass the air source into the air storage chamber 5 at this time; after the clean water enters the liquid storage chamber 8, it enters the second channel 11 and the mixing chamber 13 in sequence, and then enters the porous glass plate absorption tube through the delivery pipe 15 to rinse the cleaning liquid in the porous glass plate absorption tube. In this process, since the air source on-off device is a structure similar to the one-way valve 10, the liquid in the mixing chamber 13 will not flow out from the side of the air storage chamber 5;

[0076] In the third stage, the porous glass plate absorption tube is dried. At this time, there is no need to introduce the cleaning medium into the liquid storage chamber 8. It is only necessary to introduce gas into the gas storage chamber 5. The gas enters the mixing chamber 13 from the gas storage chamber 5 through the first channel 12 and then enters the porous glass plate absorption tube to accelerate the drying of the porous glass plate absorption tube. In this process, since the output end of the liquid storage chamber 8 is installed with a one-way valve 10, the drying gas will not flow out from one side of the liquid storage chamber 8.

[0077] In the present application, the cleaning, rinsing and drying process does not require frequent disassembly of the device and the porous glass plate absorption tube, which avoids the impact of disassembly on the cleaning speed and the damage of the porous glass plate absorption tube; in the present application, the cleaning medium or rinse water is pumped into the liquid storage chamber 8 by the water pump 17, and the gas is pumped into the gas storage chamber 1 by the air pump 16. That is, the input end of the gas storage chamber 1 is connected to the output end of the air pump 16, the input end of the liquid storage chamber 8 is connected to the output end of the water pump 17, and the input end of the water pump 17 is inserted into the water storage tank 18.

[0078] The above are only a few embodiments of the present application and do not constitute any form of limitation to the present application. Although the present application is disclosed as above with preferred embodiments, it is not intended to limit the present application. Any technician familiar with the profession, without departing from the scope of the technical solution of the present application, using the technical content disclosed above to make slight changes or modifications are equivalent to equivalent implementation cases and fall within the scope of the technical solution.
