Description

Technical Field

[0001] The utility model relates to the technical field of water treatment equipment, in particular to a vacuum degasser. Background Art

[0002] The vacuum degasser pumps a portion of the water in the circulating system into a water tank for vacuum degassing. According to Henry's law, under vacuum conditions, this portion of gas will be completely separated from the water and discharged through the degasser's vent port. The degassed, absorbent water is then injected back into the system. This highly absorbent, unsaturated water will absorb the gas in the system again to achieve gas-water solubility equilibrium. The vacuum degasser repeats this cycle every 30 seconds, and both free and dissolved gases in the water are removed during this cycle.

[0003] However, in real-world use, if there are suspended particles, sediment, or other impurities in the water, they will not be effectively removed during the degassing process. These impurities will flow into the degassing tank with the water and adhere to its internal surfaces. Over time, these impurities may form a coating on the inside of the degassing tank, which will not only affect the cleanliness of the tank but also its degassing efficiency. Utility Model Content

[0033] Base plate 1;

[0034] The water supply pump 2 is mounted on the surface of the base plate 1, and a water inlet pipe 21 is fixedly connected to the inside of the water supply pump 2;

[0036] The driving mechanism 4 is located on the upper surface of the degassing tank 3 and is used to clean the inner wall of the degassing tank 3. The driving mechanism 4 includes a scraper 43. The scraper 43 is slidably connected to the inside of the degassing tank 3. The outer wall of the scraper 43 is movably fitted with the inner wall of the degassing tank 3.

[0037] The control mechanism 5 is located on the surface of the base plate 1 and is used to control the operation of the water supply pump 2, the degassing tank 3 and the driving mechanism 4. The control mechanism 5 includes a control box 51, which is fixedly mounted on the surface of the base plate 1;

[0038] In this embodiment: the control mechanism 5 controls the water supply pump 2 to transport water to the degassing tank 3, and at the same time starts the driving mechanism 4, which scrapes impurities on the inner wall of the degassing tank 3 and filters the water transported to the degassing tank 3 by the water inlet pipe 21.

[0039] Specifically, such as Figure 3 As shown, the driving mechanism 4 also includes a motor 41, which is fixedly mounted on the surface of the degassing tank 3. The output end of the motor 41 is transmission-connected to a reciprocating screw 42, and a scraper 43 is threadedly connected to the surface of the reciprocating screw 42.

[0040] In this embodiment, when the motor 41 is working, the reciprocating screw 42 rotates, and the scraper 43 moves up and down on the surface of the reciprocating screw 42. The outer wall of the scraper 43 fits against the inner wall of the degassing tank 3, thereby scraping away impurities on the inner wall of the degassing tank 3.

[0041] Specifically, such as Figure 3 As shown, a driving sprocket 44 is fixedly mounted on the surface of the reciprocating screw 42, a fixed block 45 is fixedly mounted on the surface of the degassing tank 3, a rotating bracket 46 is rotatably connected to the fixed block 45, a driven sprocket 47 is fixedly mounted on the surface of the rotating bracket 46, a chain 48 is meshed with the surface of the driving sprocket 44 and the driven sprocket 47, and a plurality of activated carbon adsorption plates 49 are fixedly mounted on the surface of the rotating bracket 46;

[0042] In this embodiment, as the reciprocating screw 42 rotates, the driving sprocket 44 rotates, and the rotating bracket 46 is able to rotate through the meshing action of the chain 48, the driving sprocket 44, and the driven sprocket 47. The rotating bracket 46 drives the activated carbon adsorption plate 49 to rotate to filter the water source transported from the water inlet pipe 21 to the degassing tank 3, thereby effectively removing impurities in the water source. The activated carbon adsorption plate 49 is trapezoidal to increase the adsorption area.

[0043] Specifically, such as Figure 2 As shown, a heater 32 is fixedly mounted on the surface of the degassing tank 3, an anti-corrosion plate 33 is fixedly mounted on the inner wall surface of the degassing tank 3, a scraper 43 is movably fitted with the surface of the anti-corrosion plate 33, an inclined plate 34 is fixedly mounted on the inner bottom of the degassing tank 3, a water outlet pipe 35 and a sewage pipe 36 are fixedly connected to the surface of the degassing tank 3, and a solenoid valve 37 is fixedly mounted on the surface of both the water outlet pipe 35 and the sewage pipe 36;

[0044] In this embodiment: the heater 32 heats the interior of the degassing tank 3 so that the gas in the water source can be quickly released. The anti-corrosion plate 33 improves the corrosion resistance of the degassing tank 3 and extends the service life of the degassing tank 3. The inclined plate 34 guides the impurities scraped off by the scraper 43 so that the impurities can be collected and discharged at the drain pipe 36. The drain pipe 36 is located below the water outlet pipe 35. After the degassed water source inside the degassing tank 3 is discharged, the impurities at the bottom of the degassing tank 3 are discharged. The solenoid valve 37 is controlled by the control mechanism 5.

[0045] Specifically, such as Figure 4 As shown, a water inlet 38 is provided on the surface of the degassing tank 3, a support plate 39 is fixedly installed on the surface of the water inlet 38, a rotating bracket 46 is rotatably connected to the surface of the support plate 39, a filter screen 401 is detachably installed inside the fixed block 45, a through groove 402 is provided on the surface of the fixed block 45, and the filter screen 401 is movably inserted inside the through groove 402.

[0046] In this embodiment, the water source of the water inlet pipe 21 is transported to the interior of the degassing tank 3 through the water inlet 38 , the support plate 39 supports the rotating bracket 46 , and the filter screen 401 filters the particulate matter in the water source, and the filter screen 401 can be replaced through the through slot 402 .

[0047] Specifically, such as Figure 2 As shown, a regulating valve 22 is fixedly installed on the surface of the water inlet pipe 21, and a pressure gauge 23 is fixedly installed on the surface of the water inlet pipe 21;

[0049] Specifically, such as Figure 2 As shown, a thermometer 52 and a plurality of switches 53 are fixedly mounted on the surface of the control box 51. The output end of the control box 51 is electrically connected to the water supply pump 2, the regulating valve 22, the exhaust valve 31, the heater 32, the two solenoid valves 37 and the input end of the motor 41.

[0050] In this embodiment, the water supply pump 2, the regulating valve 22, the exhaust valve 31, the heater 32, the two solenoid valves 37 and the motor 41 are controlled by the control box 51 to realize the overall operation of the device.

[0051] This solution is specifically as follows: when degassing is required, the water supply pump 2 is controlled by the control mechanism 5 to transport water to the inside of the degassing tank 3, and the driving mechanism 4 is started at the same time. At this time, the motor 41 is started, the reciprocating screw 42 rotates, and the scraper 43 moves up and down on the surface of the reciprocating screw 42. The outer wall of the scraper 43 is in contact with the inner wall of the degassing tank 3, thereby scraping off impurities on the inner wall of the degassing tank 3. At the same time as the reciprocating screw 42 rotates, the driving sprocket 44 rotates, and the chain 48 engages with the driving sprocket 44 and the driven sprocket 47, so that the rotating bracket 46 can rotate. The rotating bracket 46 drives the activated carbon adsorption plate 49 to rotate to filter the water source transported from the water inlet pipe 21 to the inside of the degassing tank 3, and the filter screen 401 filters the particulate matter in the water source, thereby effectively removing impurities in the water source.
