Description

Technical Field

[0001] This utility model belongs to the field of unit purging technology, specifically referring to a multi-functional unit purging device. Background Technology

[0002] The aluminum plant currently uses double-beam trolleys for a series of multi-functional units. When performing maintenance work on the main beam of the unit, it is a high-altitude operation. Due to the complex structure of the equipment, there are certain safety hazards for the operator. After repeated tests and analysis, a blower was added to the tool cart to achieve the purpose of automatic purging and eliminate the safety hazards caused by the unit maintenance.

[0003] The unit maintenance operation involves two operators pulling a 25-meter-long, 6-point air duct back and forth on the upper beam to perform purging. Currently, the unit only has one guardrail on the compressor side beam. Due to the weight of the duct, it is difficult and extremely dangerous for the operators to drag it during the purging operation. Although there are guardrails on both sides of the other beam, there are many tripping obstacles such as cable trays and fixed hanging supports, which pose a risk of tripping during the purging operation and cause unsafe incidents for the operators. Therefore, a multi-functional unit purging device is proposed. Utility Model Content

[0004] The technical problem this utility model aims to solve is that during the purging operation, the weight of the pipe makes dragging difficult and extremely dangerous for the operator. Although there are guardrails on both sides of the main beam, there are many tripping obstacles such as cable trays and fixed hanging supports, which pose a risk of tripping for the operator during the purging operation.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a multi-functional unit purging device, including a tool cart and a mobile platform set on the tool cart, a wind exhaust fixedly set on the mobile platform, an air compressor connected to the wind exhaust fixedly set on the upper end of the tool cart, and an air outlet assembly connected to one side of the wind exhaust.

[0006] Furthermore, one end of the exhaust fan is connected to an air supply pipe, and the other end of the air supply pipe is fixedly connected to the air compressor.

[0007] Furthermore, the air outlet assembly includes air outlet three (8), air outlet one, and air outlet two, which are linearly arrayed and fixed to the side wall of the air duct.

[0008] Furthermore, the lengths of the first air outlet, the second air outlet, and the third air outlet (8) decrease sequentially.

[0009] Furthermore, the exhaust fan is fixed to the mobile platform by welding.

[0010] The beneficial effects of this utility model by adopting the above structure are as follows:

[0011] The structure adopts a tool cart, air compressor and air vent purging. The air compressor provides the air source, which enters the air vent through the air supply pipe. Multiple air outlets welded on one side of the air vent blow the air onto the main beam, replacing the operator pulling the air pipe to purge, thereby reducing safety hazards and preventing accidents.

[0012] Air nozzle one, air nozzle two, and air nozzle three are set with different lengths, resulting in different blowing effects. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Example:

[0020] refer to Figure 1-3 As shown, in order to achieve the above functions, the technical solution adopted by this utility model is as follows: a multi-functional unit purging device, including a tool cart 1 and a mobile platform 2 set on the tool cart 1. A fan 3 is fixedly set on the mobile platform 2. An air compressor 5 connected to the fan 3 is fixedly set on the upper end of the tool cart 1. An air outlet assembly is connected to one side of the fan 3. After the work of this shift is completed, the tool cart 1 is driven to the designated position, the fan 3 is opened, and the air compressor 5 is started to deliver air.

[0021] One end of the air duct 3 is connected to the air supply pipe 4, and the other end of the air supply pipe 4 is fixedly connected to the air compressor 5. The air outlet assembly includes air outlet 3 8, air outlet 1 6 and air outlet 2 7, which are fixedly connected to the side wall of the air duct 3 in a linear array. The air output by the air compressor 5 is blown onto the main beam for cleaning through air outlet 3 8, air outlet 1 6 and air outlet 2 7 on the side wall of the air duct 3.

[0022] To achieve different purging functions, such as Figure 3 As shown, the air duct 3 is fixed to the mobile platform 2 by welding. The lengths of air outlet 1 6, air outlet 2 7, and air outlet 3 8 decrease sequentially. The length of air duct 3 is 165cm. Air duct 3 and air outlets 1 6, 2 7, and 3 8 are welded together with steel pipes with extensions of 50cm, 40cm, and 20cm respectively, and are spaced 30cm apart. When air outlet 1 6 is cleaning, its longer length and wider coverage allow for more even cleaning of the beam surface and fewer missed spots. When air outlet 3 8 is cleaning, its shorter airflow path and lower energy loss result in a higher airflow speed and stronger wind.
