Technical Field

[0001] This utility model relates to the field of copper powder deep processing technology, specifically a dust collection device for baking powder. Background Technology

[0002] Ultrafine copper powder is a copper powder with a very small diameter. Due to its unique particle size and properties, ultrafine copper powder has a wide range of applications in many fields, such as electronic materials, lubricants, catalysts, coatings and coatings, 3D printing, and metal injection molding. In the processing and production of ultrafine copper powder, copper plates need to be sheared, punched and electrolyzed first. Then, the powder is pulled, washed, dried, fluidized and ball-milled to obtain the finished product. During the drying process, some copper powder will drift to the outside with the hot air, which will greatly increase dust pollution and cause a lot of waste of raw materials. Utility Model Content

[0003] The purpose of this invention is to provide a dust collection device for drying copper powder, so as to solve the problem of dust pollution caused by the airflow during the drying process of copper powder mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a dust collection device for baking powder, comprising a housing, an air inlet on the outer surface of the housing, an air outlet fixedly installed at the end of the housing away from the air inlet, a vertical bucket fixedly connected to one end of the air outlet, and a turbine fan fixedly connected to one end of the vertical bucket. One end of the air inlet is connected to the air outlet of the baking powder machine. A maintenance and cleaning window is provided on the outer surface of the housing, located between the air inlet and the air outlet. Water inlet and outlet valves are provided on the outer surfaces of both ends of the housing. A spraying mechanism is provided inside the housing, which allows water to fully contact the air mixed with copper powder entering the housing, thereby removing the copper powder from the air and reducing pollution caused by dust.

[0005] Preferably, the spraying mechanism includes: a water pump, which is placed on the ground and has its input end located at one end of the housing near the air inlet. An atomizing spray pipe is fixedly installed at the top of the housing. The output end of the water pump passes through the side surface of the housing, and a valve is fixedly installed on the side surface of the housing. The atomizing spray pipe is connected to the valve, and the valve is connected to the water pump. Another atomizing spray pipe is fixedly installed inside the air outlet cylinder, and the atomizing spray pipe is located at the top inside the air outlet cylinder.

[0006] By adopting the above technical solution, the gas containing copper powder sent into the chamber can fully contact the water mist sprayed from the atomizing spray pipe, and the water pump can draw water from the chamber for repeated use to remove copper powder from the air and reduce copper powder pollution to the environment.

[0007] Preferably, the interior of the housing is designed to be inclined, and the end of the housing closest to the air inlet is the lowest point. A water nozzle is fixedly installed at the end of the housing away from the air outlet, and the water nozzle is connected to the output end of the water pump.

[0008] Using the above technical solution, water is pumped by a water pump and sprayed outward through a flushing nozzle. The sprayed water washes away the copper powder falling down the slope inside the tank, allowing the settled copper powder to be concentrated on the side of the tank near the water pump.

[0009] Preferably, the end of the vertical barrel closest to the turbine fan is designed to be inclined, and the end of the turbine fan located inside the vertical barrel protrudes inward. A water pipe is installed through the outer surface of the vertical barrel, and the water pipe is close to the turbine fan.

[0010] By adopting the above technical solution, the water generated after steam condensation can be collected through a protruding part inside the vertical barrel, and the water can be allowed to flow out from the water pipe, so that the condensed water will not enter the interior of the turbine fan.

[0011] Preferably, a side sealing door is rotatably mounted on the side surface of the enclosure, and a long strip-shaped observation window is embedded in the outer surface of the side sealing door. A sealing gasket is provided between the side sealing door and the enclosure.

[0012] By adopting the above technical solution, the remaining water in the tank can be accurately determined through the observation window on the outer surface of the side sealing door, and the amount of copper powder that has been flushed and concentrated can be observed, whether the side sealing door needs to be opened to recover the copper powder, and whether water needs to be added.

[0013] Preferably, a fixing bolt is fitted onto the outer surface of the housing near the air inlet, and the fixing bolt is in contact with the outer surface of the housing, and the fixing bolt is engaged with the side sealing door.

[0014] Using the above technical solution, the side sealing door can be fixed and sealed by fixing bolts. When the fixing bolts are damaged, they can be removed from the outside of the box and replaced with new fixing bolts.

[0015] Preferably, an isolation filter cover is inserted and installed on the inner surface of the end of the box near the side sealing door, and the isolation filter cover and the input end of the water pump are concentrically designed. An elastic pin is slidably installed on the end of the box near the observation window, and one end of the elastic pin is inclined. The elastic pin engages with the isolation filter cover, and the outer surface of the isolation filter cover is tightly fitted with the outer surface of the box.

[0016] By adopting the above technical solution, the isolation filter cover can be easily inserted into the inside of the box. During the insertion process, the isolation filter cover pushes the elastic pin, and after the isolation filter cover is inserted into place, the elastic pin moves automatically and engages with the isolation filter cover. This allows the isolation filter cover to be easily installed and fits tightly against the outer surface of the box, and prevents copper powder from entering the atomizing spray pipe and causing blockage when the water pump is drawing water.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the dust collection device for baking powder:

[0018] 1. As the powder drying machine operates, air mixed with copper powder will enter the interior of the chamber through the air inlet. With the operation of the water pump, water inside the chamber will be pumped into the atomizing spray pipe and sprayed outward, so that the sprayed water mist can fully contact the copper powder in the air, allowing the copper powder to be adsorbed and fall into the interior of the chamber, thereby reducing and minimizing dust pollution to the air environment.

[0019] 2. As the copper powder comes into contact with the water mist, the copper powder will settle and fall to the bottom of the chamber. With the operation of the water pump, water is sprayed out from the flushing nozzle. The sprayed water will wash away the copper powder along the inclined surface of the chamber, so that the copper powder is concentrated on the side of the chamber near the side sealing door. When there is no gas that needs to be removed, the valve can be closed to increase the water spray pressure of the flushing nozzle, so that the copper powder can be flushed more concentrated, making it easier to collect the copper powder.

[0020] 3. The observation window on the outer surface of the side sealing door can effectively determine the amount of water remaining in the chamber and the amount of copper powder that has been collected. When it is necessary to clean the inside of the chamber, the water in the chamber can be drained through the inlet and outlet valves. Then, the fixing bolts can be loosened to open the side sealing door, making it convenient to remove and recycle the dust collected in the chamber, reducing the waste of raw materials and lowering production costs.

[0028] 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.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a dust collection device for baking powder, including a box 1, an air inlet 2 on the outer surface of the box 1, an air outlet 3 fixedly installed at the end of the box 1 away from the air inlet 2, and a vertical bucket 4 fixedly connected to one end of the air outlet 3, and a turbine fan 5 fixedly connected to one end of the vertical bucket 4. One end of the air inlet 2 is connected to the air outlet of the baking powder machine. An inspection and cleaning window 16 is provided on the outer surface of the box 1, and the inspection and cleaning window 16 is located between the air inlet 2 and the air outlet 3. Water inlet and outlet valves are provided on the outer surfaces of both ends of the box 1. A spraying mechanism is provided inside the box 1. The spraying mechanism allows water to fully contact the air mixed with copper powder entering the box 1, thereby removing the copper powder in the air and reducing the pollution caused by dust.

[0030] During the drying process, the gas containing copper powder will enter the interior of the chamber 1 through the air inlet 2. After the operation of the turbine fan 5, the gas containing copper powder will move in the direction of the air outlet 3 and the vertical barrel 4. After dust removal, it will be discharged outward. The inspection and cleaning window 16 can be opened to facilitate maintenance and cleaning of the interior of the chamber 1.

[0031] The spraying mechanism includes: a water pump 9, which is placed on the ground and has its input end located at one end of the housing 1 near the air inlet 2. An atomizing spray pipe 13 is fixedly installed on the top of the housing 1. The output end of the water pump 9 passes through the side surface of the housing 1 and a valve 11 is fixedly installed on the side surface of the housing 1. The atomizing spray pipe 13 is connected to the valve 11 and the valve 11 is connected to the water pump 9. Another atomizing spray pipe 13 is fixedly installed inside the air outlet 3 and is located at the top of the air outlet 3.

[0032] As the gas containing copper powder enters the housing 1, the water pump 9 pumps the water out of the housing 1, causing the water to be sprayed outward from the atomizing spray pipe 13 through the pipe. The valve 11 controls whether the atomizing spray pipe 13 sprays water outward, so that the sprayed water mist can fully contact the copper powder in the air to remove the copper powder. When the copper powder enters the interior of the exhaust pipe 3, it will come into contact with the water mist again to completely remove the copper powder, thereby reducing and minimizing dust pollution.

[0033] The interior of the housing 1 is designed to be inclined, and the end of the housing 1 closest to the air inlet 2 is the lowest point. A water nozzle 12 is fixedly installed at the end of the housing 1 away from the air outlet 3, and the water nozzle 12 is connected to the output end of the water pump 9.

[0034] As the water pump 9 operates, the water nozzle 12 sprays water outward, causing the settled copper powder to be washed away by the water along the inclined surface inside the box 1. When cleaning the inside of the box 1 later, the atomizing spray pipe 13 can be closed by the valve 11 to increase the flushing volume of the water nozzle 12, so that the fallen copper powder can be concentrated at the end of the box 1 near the air inlet 2, which facilitates the collection and removal of copper powder and reduces product waste.

[0035] The end of the vertical barrel 4 near the turbine fan 5 is designed to be inclined, and the end of the turbine fan 5 located inside the vertical barrel 4 protrudes inward. A water pipe 10 is installed through the outer surface of the vertical barrel 4, and the water pipe 10 is close to the turbine fan 5.

[0036] As the gas discharged from the powder dryer comes into contact with water, air carrying water vapor is generated. When this air enters the vertical barrel 4, condensation will form on the inner wall of the vertical barrel 4. The condensation will flow down the inclined surface of the vertical barrel 4 and then be discharged to the outside through the drain pipe 10, reducing the chance of condensation entering the turbine fan 5, preventing the condensed water from flowing onto the ground everywhere, and reducing the chance of damage to the turbine fan 5.

[0037] A side sealing door 6 is rotatably installed on the side surface of the enclosure 1, and a long strip-shaped observation window 8 is inlaid on the outer surface of the side sealing door 6. A sealing gasket is provided between the side sealing door 6 and the enclosure 1.

[0038] The observation window 8 on the outer surface of the side sealing door 6 allows for effective observation of the remaining water inside the tank 1 and the amount of copper powder collected together. This facilitates the determination of whether water needs to be added, or whether the water inside the tank 1 needs to be drained and the collected copper powder can be removed by opening the side sealing door 6.

[0039] A fixing bolt 7 is installed on the outer surface of the end of the housing 1 near the air inlet 2, and the fixing bolt 7 is in contact with the outer surface of the housing 1. The fixing bolt 7 is engaged with the side sealing door 6.

[0040] The side sealing door 6 can be fixed by the fixing bolt 7 to prevent it from opening. When the fixing bolt 7 is damaged after long-term use, it can be removed from the box 1 and a new fixing bolt 7 can be inserted, which reduces the difficulty of replacing the fixing bolt 7 and facilitates the replacement of consumable parts.

[0041] An isolation filter cover 14 is inserted and installed on the inner surface of the end of the housing 1 near the side sealing door 6. The isolation filter cover 14 and the input end of the water pump 9 are concentrically designed. An elastic pin 15 is slidably installed on the end of the housing 1 near the observation window 8. One end of the elastic pin 15 is inclined. The elastic pin 15 is engaged with the isolation filter cover 14, and the outer surface of the isolation filter cover 14 is tightly fitted with the outer surface of the housing 1.

[0042] The isolation filter cover 14 effectively isolates copper powder when the water pump 9 is pumping water, preventing copper powder from entering the atomizing spray pipe 13 with the water flow and causing blockage. Furthermore, the inclined surface of the elastic pin 15 allows the isolation filter cover 14 to be directly inserted into the inner surface of the housing 1 when it is installed. This allows the isolation filter cover 14 to push the elastic pin 15 to move. When the isolation filter cover 14 is inserted into place, the elastic pin 15 automatically springs back and engages with the isolation filter cover 14.

[0043] 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.
