Description

Technical Field

[0001] This utility model relates to a dust collection device, and more particularly to a multi-functional overhead crane dust collection device for electrolytic aluminum, belonging to the field of electrolytic aluminum technology. Background Technology

[0002] During the production and operation of the electrolytic aluminum industry, especially during the electrode replacement process, the negative pressure inside the electrolytic cell purification system drops significantly after the cell cover is opened. This causes the flue gas inside the cell, along with high-temperature particulate matter from the anode, to escape into the atmosphere, affecting the health of on-site workers, worsening the working environment, and severely damaging the atmospheric environment. Under current production conditions and environments, there is still no effective way to accurately recover this flue gas. Some electrolytic aluminum plants use spray systems to suppress dust, but these systems suffer from rapid evaporation rates at high temperatures, rendering them ineffective in dust suppression. Furthermore, these systems have a short lifespan in high-temperature environments and pose significant safety hazards. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a multi-functional overhead crane dust collection device for electrolytic aluminum. By setting a dust collection hood around the double anode wrench, the device can recover the smoke generated during the electrode switching process under the action of an air compressor, thus ensuring a good working environment.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] A multi-functional overhead crane dust collection device for electrolytic aluminum includes a dust collection hood, a dust collection pipe, and an air compressor. The dust collection hood is U-shaped and fixedly connected to a double anode wrench via support rods. Dust collection holes are provided at the bottom of the dust collection hood. A dust collection pipe is provided on the right side of the top of the dust collection hood. An overhead crane air compressor is provided at the end of the dust collection pipe. A high-temperature resistant lining is provided around the bottom of the dust collection hood.

[0006] The dust collection hood is installed around the outside of the double anode wrench, and the distance between the inner wall of the dust collection hood and the outer wall of the double anode wrench is 20cm.

[0007] The outer wall of the dust collection hood is provided with a collar, and a storage hook passes through the collar and is fixed by a tightening bolt, which is located on the outer wall of the collar.

[0008] There are two support rods, which are respectively installed on both sides of the dust collection hood. The bottom of the support rod is fixedly connected to the top of the dust collection hood, and the top of the support rod is fixedly connected to the side wall of the double anode wrench.

[0009] The positive and beneficial effects of this utility model are:

[0010] 1. This utility model, by setting a dust collection hood around the double anode wrench, can recover the smoke generated during the anode switching process under the action of the air compressor, and can effectively control local smoke and dust by utilizing the characteristics of moving with the traveling tool mechanism, thus avoiding environmental pollution in the workshop. It is convenient to use and simple to operate.

[0011] 2. This utility model achieves a good dust collection effect by setting a high-temperature lining at the bottom of the dust collection hood to prevent the escape of smoke and secondary pollution during the dust collection process.

[0012] 3. This utility model has a collar on the outer wall of the dust collection hood, and a storage hook passes through the collar. When the device is not in use, the high-temperature resistant cloth can be put away using the storage hook, and the storage hook can be fixed by tightening bolts, which makes it convenient for workers to put away the high-temperature resistant cloth.

[0016] The present invention will be further explained and described below with reference to the accompanying drawings:

[0017] See the example. Figures 1-2 A multi-functional overhead crane dust collection device for electrolytic aluminum includes a dust collection hood 1, a dust collection pipe 4, and an air compressor 5. The dust collection hood 1 is U-shaped and is fixedly connected to a double anode wrench 3 by a support rod 2. A dust collection hole 101 is provided at the bottom of the dust collection hood 1. A dust collection pipe 4 is provided on the right side of the top of the dust collection hood 1. An overhead crane air compressor 5 is provided at the end of the dust collection pipe 4. A high-temperature resistant lining cloth 6 is provided around the bottom of the dust collection hood 1.

[0018] The dust collection hood 1 is set around the outside of the double anode wrench 3, and the distance between the inner wall of the dust collection hood 1 and the outer wall of the double anode wrench 3 is 20cm.

[0019] A collar 7 is provided on the outer wall of the dust collection hood 1, and a storage hook 8 passes through the collar 7 and is fixed by a tightening bolt, which is located on the outer wall of the collar 7.

[0020] There are two support rods 2, which are respectively set on both sides of the dust collection hood 1. The bottom of the support rod 2 is fixedly connected to the top of the dust collection hood 1, and the top of the support rod 2 is fixedly connected to the side wall of the double anode wrench 3.

[0021] In the above description, the overhead air compressor is installed on the overhead crane.

[0022] In the above description, the dust collection hood is installed in parallel around the double anode wrench. Different models and sizes of dust collection hoods are selected according to the different clearances of the multi-functional crane. It can accurately adsorb the polluted area during the electrode replacement operation. High-temperature flue gas and solid pollutants enter the dust collection hood through the dust collection holes under the negative pressure of the crane's air compressor and then enter the air compressor connecting pipe.

[0023] In the above description, the overhead air compressor provides negative pressure and collects the smoke and dust into the dust collection hood through the air compressor connecting pipe. The bottom of the dust collection hood is fitted with high-temperature resistant sealing cloth by using rivets to completely seal the surrounding gaps. Because the high-temperature resistant sealing cloth has good air permeability, the negative pressure provided by the overhead air compressor can efficiently adsorb the smoke and dust with low loss, achieving a good dust collection effect.

[0024] In the above description, the dust collection duct connects the overhead air compressor to the dust collection hood, and the negative pressure provided by the overhead air compressor forms an adjustable negative pressure at the dust collection port for flue gas collection.

[0025] In the above description, compared with most of the traditional spraying devices currently used in China, this device uses mechanical welding, which can effectively reduce equipment failure rate, reduce maintenance costs, is more adaptable to high-temperature working environments, and reduce safety accidents caused by equipment damage.

[0026] This invention features a dust collection hood around a double-anode wrench. Under the action of an air compressor, it can recover the smoke generated during the electrode switching process. Furthermore, it can effectively control localized dust by utilizing the movement characteristics of the traveling tool mechanism, thus avoiding environmental pollution in the workshop. It is convenient to use and easy to operate.
