Description

Technical Field

[0001] The invention relates to the technical field of dust removal equipment, and in particular to waste heat recovery dust removal equipment for dryer processing. Background Art

[0002] At present, the dryers used for textile, bleaching and dyeing, and drying of grey cloth after washing are not equipped with waste heat recovery. Since the heat energy of the dryer is mobile and used for a short distance, it is discharged as exhaust gas through the fan, which causes serious waste of heat energy. The exhaust gas from the dryers of most units contains a large amount of fiber dust, which is directly discharged without treatment, polluting the environment to a great extent and endangering the health of employees.

[0003] For example, a Chinese patent with the publication (announcement) number CN202099597U discloses a waste heat recovery and dust removal device for a dryer, which is mainly composed of a waste heat gas connecting pipe, a waste heat recovery heat exchanger assembly, a dust collector, a natural air inlet, a waste heat gas recycling connecting pipe, recovered heat energy for recycling, a dryer source heat energy supply displacer, a dryer body, etc., and is characterized in that the waste heat gas discharge port is connected to the waste heat recovery heat exchanger assembly through the waste heat gas connecting pipe, the waste heat gas enters the dust collector after heat exchange, and is discharged after dust removal.

[0004] Although the above technical solution solves the corresponding technical problem, the dust removal device in the above technology is not convenient for cleaning the filtered dust, thereby reducing the practicality of the dust removal device. Summary of the invention

[0005] The object of the present invention is to provide a waste heat recovery dust removal equipment for dryer processing, wherein the air to be processed is introduced into the dust removal shell through the air inlet, and the air is first preliminarily filtered through the disc filter. During the filtering process, the dust attached to the disc filter can be easily collected through the first dust collecting head, thereby improving the filtering effect of the air, and then the air is filtered again through the dust filter. At the same time, the dust on the dust filter can be centrally collected through the second dust collecting head and concentratedly collected in the dust collecting shell. While the dust inside the dust collecting shell is discharged through the dust outlet, the servo motor is turned on, and the servo motor drives the cam at the bottom of the driving rod to squeeze the force plate with different radii. Therefore, under the elastic force of the sleeve spring, the knocking block can be driven to move back and forth continuously, so that the dust outlet can be continuously knocked by the knocking block, thereby improving the convenience and thoroughness of dust discharge, and thus improving the practicality of the present invention.

[0006] In order to achieve the above object, the main technical solutions adopted by the present invention include:
