Description

Air filter cleaning device

Technical field:

The utility model belongs to the technical field of cleaning equipment, and in particular relates to an air filter cleaning device.

Background technology:

The locomotive roof air filter is an important part of the HXD3 electric locomotive cooling and ventilation system, which can filter out relatively large dust and rainwater. Long-term accumulation of dust will seriously increase the air intake resistance of the ventilation system, affect the cooling effect of the locomotive traction motor, transformer, and converter, and further affect the operation of the locomotive. Therefore, the locomotive roof air filter must be cleaned regularly to ensure smooth air intake of the ventilation system.

HXD3 top cover filter has two types: palm fiber air filter and side wall plate air coarse filter. Among them, the outer layer of the palm fiber air filter is cloth, and the inner layer is filled with palm fiber. It is now mostly cleaned by manual back-blowing or high-power vacuum cleaners, and it is strictly forbidden to use (industrial washing machine) water washing to prevent damage and deformation. Due to the lack of dust prevention and dust reduction measures, high-pressure air blows up dust and flies everywhere, making the working environment harsh and causing secondary pollution. In addition, this operation mode has high labor intensity and low cleaning efficiency, which seriously affects the turnover efficiency and service life of the palm fiber air filter and increases the material cost expenditure of the locomotive depot.

At present, under normal weather conditions (atmospheric dust content TSP≤0.2mg/ ^m3 ), the top cover air filter is removed and cleaned every 4-6 kilometers of minor repair mileage. However, the locomotive lines in the northwest region are dry and rainy, with frequent sandstorms. Especially from March to May every year, the wind and sand mixed with poplar and willow catkins are easily attached to the palm fiber air filter. The cleaning effect of a single back-blowing or dust suction method is not ideal. If not handled in time, the locomotive related electrical appliances will be damaged due to overheating, seriously affecting the normal operation of the ventilation system. In order to ensure the safety of locomotive operation, the locomotive depot can only increase the cleaning frequency of the top cover air filter, further increasing the workload of employees.

In view of the above situation, it is necessary to develop professional locomotive top cover brown fiber air filter cleaning equipment to change the existing cleaning operation mode, improve operation efficiency, enhance cleaning effect, improve working environment and reduce labor intensity.

The four devices are sequentially arranged and interlocked, and the air filter can be cleaned more thoroughly. In addition, if the palm fiber air filter is severely deformed after cleaning or cannot cover the Φ1.8×10×10 steel plate mesh after shrinkage, it shall not be used any more and should be scrapped. The cleaning device uses the rolling brush device, the flexible rapping device, and the rigid rapping device to clean in sequence, with the force increasing from small to large, and the contact time can be controlled by the manual control console. In conjunction with the transmission wheel group, the deformation caused by the cleaning process can be reduced as much as possible.

The air filter is placed on the feed conveyor belt, and the front end of the air filter is stuck between the first transmission upper shaft and the first transmission lower shaft close to the feed conveyor belt. The transmission wheel group, the roller brush device, the flexible vibration device, and the rigid vibration device are started through the control console. After roller brushing, multiple beatings, and back-blowing cleaning, the sand, poplar and willow catkins, etc. carried in the air filter are cleaned and fall into the dust collecting chamber below the dust removal chamber.

The arrangement of the limit stopper, the slide bar frame and the feed stopper is conducive to the air filter not being offset in the dust removal mechanism, and can be accurately clamped between the transmission upper shaft and the transmission lower shaft and moved to the position of the discharge conveyor belt. Specifically, the limit stopper is arranged on the first and second transmission upper shafts in the forward direction of the air filter, and cooperates with the roller brush device below to prevent the air filter from being offset upward or downward when placed in the dust removal chamber, and can be clamped between the transmission wheel of the transmission upper shaft and the transmission wheel of the transmission lower shaft. The arrangement of the slide bar frame allows the slide bar to serve as a protection to prevent the air filter from being offset downward by the force of the flexible rapping device and the rigid rapping device when continuing to move forward, thereby causing it to be stuck between the transmission wheel groups. The arrangement of the limit stopper can play a guiding role on the left and right sides of the forward direction of the air filter to prevent the air filter from offsetting to the left or right.
