Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-5 This utility model provides an embodiment of a dust collection device for cutting building decoration materials, comprising a dust collection device 1 and a high-pressure blower 2. The dust collection device 1 includes a collection bucket 6 and a second air inlet pipe 19. The collection bucket 6 is provided with a dust baffle 12 inside. An air inlet hole 13 is provided through one side of the top of the dust baffle 12. An air outlet hole 14 is uniformly provided around the air inlet hole 13 at the top of the dust baffle 12. When the air rising from the water collides with the bottom of the dust baffle 12, it breaks into smaller bubbles and passes through the outlet. The air vent 14 discharges, thereby adsorbing more debris and sinking it to the bottom of the water. Limiting notches 15 are evenly opened on the outer side of the debris baffle 12. The bottom end of the second air inlet pipe 19 is fixedly connected to the base plate 22. The top end of the base plate 22 is evenly fixedly connected to the exhaust pipe 23. The top end of the second air inlet pipe 19 is fixedly installed with the top connecting plate 20. The bottom end of the top connecting plate 20 is evenly opened with the insertion groove 24. The top end of the top connecting plate 20 is evenly opened with the conical groove 21. The bottom end of the outer side of the second air inlet pipe 19 is fixedly connected to the support ring 25.
[0022] The top end of the second air inlet pipe 19 is fixedly installed with an elbow 18. The second air inlet pipe 19 is movably inserted into the inner side of the air inlet hole 13. The bottom end of the support ring 25 is tightly attached to the top end of the debris baffle 12. The debris baffle 12 provides support for the support ring 25. The top end of the exhaust pipe 23 is movably inserted into the inner side of the insertion groove 24. The conical groove 21 and the insertion groove 24 are connected. The conical groove 21 diverts the air to the interior of different exhaust pipes 23. The air is discharged into the water through the bottom end of the base plate 22 and generates fine bubbles. The rising speed is slow and the gas-liquid contact efficiency is high, increasing the contact surface between debris and water. The high temperature debris is cooled by water, and the debris sinks to the bottom of the water due to the resistance of the water. At the same time, the back pressure required by the high pressure blower 2 to maintain the air volume can be reduced by the diversion of the exhaust pipe 23.
[0023] A bottom support plate 16 is uniformly fixedly connected to the inner side of the collection bucket 6. A limiting block 17 is uniformly fixedly connected above the bottom support plate 16 on the inner side of the collection bucket 6. The distance between the top end of the bottom support plate 16 and the bottom end of the limiting block 17 is the same as the thickness of the debris baffle 12. The limiting block 17 and the limiting notch 15 are movably inserted. The debris baffle 12 is inserted into the outside of the limiting block 17 through the limiting notch 15 and moved downward until the bottom end of the debris baffle 12 is close to the top end of the bottom support plate 16. Then the debris baffle 12 is rotated so that the limiting notch 15 is away from the limiting block 17. At this time, the debris baffle 12 is stuck inside the collection bucket 6.
[0024] A first air inlet pipe 9 is fixedly connected to the top outer side of the collection bucket 6. One end of the first air inlet pipe 9, located inside the collection bucket 6, is fixedly installed on the elbow 18. An air inlet connecting pipe 4 is fixedly installed at the outer side of the first air inlet pipe 9. A dust suction square pipe 5 is fixedly installed at the end of the air inlet connecting pipe 4 furthest from the first air inlet pipe 9. The open end of the dust suction square pipe 5 is located at the rear end of the metal cutting machine. The cutting blades of the metal cutting machine throw the cutting debris towards the rear end, which enters the dust suction square pipe 5. An air outlet pipe 10 is fixedly connected to the top outer side of the collection bucket 6. The air outlet pipe 10 is located at the top outer side of the collection bucket 6. A metal filter screen 11 is fixedly installed at one end of the inner side of the collection tank 6. The metal filter screen 11 is used to block light debris and prevent the debris from being discharged. An air outlet pipe 10 is fixedly installed at one end of the outer side of the collection tank 6. The end of the air outlet pipe 3 away from the air outlet pipe 10 is fixedly installed at the input end of the high-pressure blower 2. The high pressure of the high-pressure blower 2 causes the air inside the exhaust pipe 23 to enter the collection tank 6 through water pressure. The end of the air outlet pipe 10 located inside the collection tank 6 is designed to be inclined downwards. The inclined design facilitates the discharge of water sucked in inside the air outlet pipe 10.
[0025] An observation window 7 is provided on the outside of the collection bucket 6. The observation window 7 is made of transparent material. It is easy to observe the water level and the amount of debris collected inside the collection bucket 6 through the observation window 7. The top of the collection bucket 6 is sealed and fixed with a top sealing cover 8 by a rubber gasket. The sealing design prevents air leakage from reducing the suction power of the vacuum tube 5.
[0026] Working Principle: During use, first place the open end of the suction tube 5 at the rear end of the metal cutting machine. Then, fill the collection bucket 6 with water until the water level exceeds the top of the debris baffle 12. Before metal cutting, start the high-pressure blower 2. The input end of the high-pressure blower 2 draws air out of the collection bucket 6 through the exhaust connection pipe 3. At this time, the air pressure inside the collection bucket 6 decreases. External air is then supplied to the collection bucket 6 through the exhaust pipe 23 to replenish and balance the air pressure, thereby activating the suction power of the open end of the suction tube 5. During metal cutting, the debris is thrown to the rear end by the cutting blade and crushed under the suction power of the open end of the suction tube 5. The debris is conveyed to the first air inlet pipe 9 and then to the top of the top connecting plate 20 through the elbow 18. At this time, the air and debris are diverted by the conical groove 21 to different exhaust pipes 23. Then, the air and debris are discharged through the bottom of the bottom plate 22. After the air containing debris comes into contact with the water, the debris disperses into the water and falls downward. Some of the debris that is carried upward by the air is blocked and falls downward when it hits the debris baffle 12. The light debris that floats to the water surface through the air outlet 14 is sucked into the air outlet pipe 10 and blocked by the metal filter screen 11. The segmented blocking by the water and debris baffle 12 and the metal filter screen 11 achieves the cooling and collection of debris.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
