Description
Technical Field
The utility model relates to the field of environmental sanitation equipment, in particular to a filter cylinder ash removal device and a sweeper.
Background
The road sweeper can be divided into a dry type dust removal sweeper and a wet type dust removal sweeper according to the dust removal mode. The wet dust removal sweeper adopts a water pump to spray water for dust removal treatment, and the type of sweeper is mainly suitable for markets in east China and south China; the main pollutants of the road surfaces in the north and west China areas are dust and fine sand grains, the cleaning operation is not facilitated by water spraying for dust fall, and the cleaning and sweeping vehicle with large water spraying amount can meet the dust fall operation, but after the cleaning and sweeping vehicle enters winter, the temperature in the areas is low, water is easy to freeze, so that the cleaning and sweeping vehicle cannot meet the operation condition, only can be sealed and stopped, and finally only can be cleaned by the dry dust removal cleaning vehicle, and therefore the market maintenance of the dry dust removal cleaning vehicle is large.
At present, dry type dust removal sweeper vehicles in the market generally adopt cloth bag dust removal or pleated filter cartridge dust removal, and most of the two dust removal modes adopt the pleated filter cartridge dust removal mode. According to the dry type dust removal sweeper, the filter cartridge is arranged at the front end of the fan in the pneumatic conveying system, and when the sweeper is used for sweeping, the centrifugal fan rotates at a high speed, so that air is always pumped to a device at the front end of the fan, the dustbin forms a certain negative pressure, and finally road surface pollutants are sucked into the dustbin through the pipeline. Therefore, the surface of the filter cylinder is always in a negative pressure state, the existing dust cleaning mode of the filter cylinder basically sprays air flow to the middle part of a filter element of the filter cylinder in a pulse spraying mode, and huge air flow flows to the periphery of the filter cylinder, so that dust on the outer surface of the filter cylinder is sprayed to be separated from the surface of the filter cylinder and falls onto a bottom plate of a garbage bin. In order to maintain continuous suction force in the operation process, the fan cannot stop working, so that when pulse dust removal is carried out, dust on the surface of the filter cylinder is simultaneously removed in the process of adsorption while being adsorbed, namely online dust removal and dust removal, and if the dust on the surface of the filter cylinder is not adsorbed by negative pressure, dust removal is carried out, namely offline dust removal and dust removal. Obviously, online dust removal deashing can lead to the deashing degree of difficulty great because of there is the adsorbed characteristics of negative pressure in the dust, and the deashing effect is relatively poor, strains the dust and can not in time clear up on the section of thick bamboo, then influences the air current and through straining a section of thick bamboo, and the box negative pressure descends, finally leads to whole car suction to descend, how to avoid appearing this kind of phenomenon, and this is the problem that the skilled person in the art waited to solve urgently.
