Description

Dust cleaning device with rotation and pulse and its cleaning method

technical field

The invention relates to dust removal equipment for a sanitation vehicle, in particular to a dust removal device with a rotating and pulsed filter cartridge for a sanitation vehicle, and also relates to a dust removal method using the dust removal device.

Background technique

With the improvement of human society's awareness of environmental protection and the continuous improvement of environmental quality requirements, sanitation products continue to develop in the direction of comprehensive, professional and intelligent.

At present, most of the vacuum cleaners and dry road sweepers used for urban road sanitation work use pleated filter cartridges to remove dust. The pulse blowing pipe blows toward the filter cartridge to achieve the effect of dust removal; the other type is to place the filter cartridge horizontally, and the pulse blowing pipe blows toward the filter cartridge to achieve the effect of dust removal. Usually, the working environment of sanitation vehicles is poor, and after working for a period of time, sanitation vehicles can find that if the filter cartridge is arranged vertically, more and more dust will accumulate at the bottom of the filter cartridge folds, while if the filter cartridge is placed horizontally , although the dust below the central axis can be cleaned cleanly, but the parts above the central axis are accumulated in the folds due to the self-weight of the dust and cannot be cleaned. The dust removal structure of the two pleated filter cartridges has the problem that the dust accumulation hinders the air from passing through the filter cartridge. Thereby reducing the defects of work vehicle suction rate.

Contents of the invention

The purpose of the present invention is to provide a dust removal device with rotation and pulse and a dust removal method thereof, so that when the sanitation vehicle uses the pleated filter cartridge to remove dust, the dust adhering to the filter cartridge can be easily cleaned. Improve the cleaning rate of the vehicle.

In order to achieve the above purpose, the cleaning device with rotation and pulse of the present invention includes a motor fixing seat, a hydraulic motor, a driving wheel, a narrow V-belt, a transmission gear, a driven wheel, a rubber pad, a mandrel, a pleated filter cartridge, a filter cartridge fixed frame, air bag and pulse valve; the shaft end of the hydraulic motor is connected to the driving wheel, and the hydraulic motor is fixed on the motor fixing seat; The shaft is fixed on the filter cartridge frame to form a group of pleated filter cartridge units. The pleated filter cartridge unit is installed in multiple groups horizontally. The shaft end of the mandrel of the pleated filter cartridge unit is equipped with transmission gears, and the adjacent transmission gears mesh with each other, so that the pleated filter cartridges of each group of pleated filter cartridge units can rotate around the mandrel.

The operation steps of the dust removal method of the dust removal device with rotation and pulse of the present invention are as follows:

The first step: Start the hydraulic motor to drive the driving wheel to rotate, and transmit it to the driven wheel set in the first group of pleated filter cartridge units through the narrow V-belt, so that the driven wheel rotates, and drives all the pleated filter cartridges to rotate around through the transmission gear. The respective mandrels rotate;

Step 2: Turn on the pulse cleaning switch, so that after a certain pressure of air is stored in the air bag, the pressure air is sprayed to the pleated filter cartridge through the pulse valve with a preset pulse time, and the pleated filter cartridge is rotated while spraying, so that It is possible to make each pleat of the pleated filter cartridge vertically downward and just receive the pulse spray, the dust will drop into the dust box by its own weight, thereby achieving the effect of dust removal.

The present invention adopts the combination of rotation and pulse to clean dust. When the sanitation vehicle is working, the hydraulic motor drives the pleated filter cartridge to rotate around the axis. After the pulse valve is opened, it sprays to the mouth of the filter cartridge according to the set interval time. The dust adhering to the filter cartridge is cleaned, and by ensuring the air permeability of the pleated filter cartridge, the absorption rate of road garbage is improved.

Through repeated operation tests, the effect is remarkable. This kind of dust cleaning device with rotation and pulse can clean the dust adsorbed on the filter cartridge without leaving any dead ends, prolong the working time of sanitation vehicles and improve working efficiency.

detailed description

The dust cleaning device with rotation and pulse and the dust cleaning method of the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

As shown in Figure 1 and Figure 2, the cleaning device with rotation and pulse of the present invention includes a motor fixing seat 1, a hydraulic motor 2, a driving wheel 3, a narrow V-belt 4, a transmission gear 5, a driven wheel 6, a rubber pad 7, Mandrel 8, pleated filter cartridge 9, filter cartridge holder 10, air bag 11 and pulse valve 12; the shaft end of the hydraulic motor 2 is connected to the drive wheel 3, and the hydraulic motor 2 is fixed on the motor holder 1; The pleated filter cartridge 9 is fixed on the filter cartridge frame 10 through a mandrel 8 with a rubber pad 7 that acts as a buffer seal at one end, forming a group of pleated filter cartridge units, and multiple groups of pleated filter cartridge units are installed horizontally. The shaft ends of the mandrels 8 of the first group of pleated filter cartridge units are equipped with driven wheels 6, and the shaft ends of the mandrels 8 of the remaining groups of pleated filter cartridge units are equipped with transmission gears 5, and the adjacent transmission gears 5 are meshed with each other, so that The pleated filter cartridges 9 of each group of pleated filter cartridge units can rotate around the mandrel.

The operation steps of the dust removal method of the dust removal device with rotation and pulse of the present invention are as follows:
