Description

Filter cartridge cleaning device

Technical Field

The utility model relates to a cleaning device, especially the cleaning device of the cartridge filter among air conditioner and the dust collecting equipment.

Background

The cylinder filter in air conditioner and dust-removing equipment, i.e. the filter cylinder is made of polyester fibre cloth (non-woven fabric), and in order to increase filtering area it adopts bending structure, so that its bending included angle is not easy to clean. At present, the cleaning is mostly carried out by adopting a manual water washing or manual compressed air blowing mode, and a mechanical water washing and pulse blowing mode is also adopted.

The manual washing mode has the problems that the bent corner is not easy to clean, the labor intensity is high, the washing time is long, one filter cartridge generally needs about 10 minutes, water resources are consumed, sewage is generated, and the cleaning cost is generally more than 1.5 yuan. Meanwhile, the filter cartridge needs to be dried or aired after being cleaned, so that the required time is long, and particularly in the air humid season, such as drying without a dryer, the filter cartridge is easy to be hardened, and the service life of the filter cartridge is shortened.

The problem that manual compressed air blowing exists is that raise dust is generated, the operation environment is influenced, and especially, the occupational health of operators is damaged. Meanwhile, the cleaning effect is poor, and the part of the bent corner is not easy to clean.

Compared with a manual washing mode, the mechanical washing mode only reduces the labor intensity of workers and improves the cleaning efficiency, but the problems that the drying is needed, the water resource is consumed and the sewage is generated are not solved, and the cleaning cost is also higher.

The cleaning by the pulse blowing mode also has the problems that part of dead corners are not cleaned completely, dust collecting equipment with larger power needs to be added, a pressure container needs to be added and the like, the cleaning cost is higher, and the filter cartridge is easy to damage due to larger pressure at the moment of pulse.

The air nozzles are F-shaped nozzles, are vertically arranged on the central air pipe and are arranged on two sides of the central air pipe in a staggered mode at intervals in two rows.

The two driving air pipes are arranged on two sides of the lower portion of the central air pipe, and the two driving air pipes are centrosymmetric about the axis of the central air pipe.

During the use, be connected intake pipe and compressed air source, the dust absorption pipe is connected with concentrated pipe or the dust catcher that gathers dust, will plan clean cartridge filter and put in cartridge filter locating rack, can carry out the cleanness of cartridge filter.

The utility model adopts the rotary blowing device, and uses the compressed air flow to blow and clean the filter cartridge in the rotation, thus effectively removing the dust at the bending included angle of the filter cartridge; because the F-shaped nozzles are adopted and vertically arranged on the central air pipe and are arranged in two rows at intervals, the filter cartridge can be covered in the whole area without dead angles when being cleaned by blowing, and therefore, the cleaning effect is good; because the rotating platform is driven to rotate by adopting the compressed air flow, the risk of dust explosion can be effectively avoided, and the dust cleaning device is suitable for cleaning various kinds of dust; because the blowing and dust removal operation is carried out in the closed box body, the pollution of the flying dust generated by blowing to the operating environment can be avoided.

Detailed Description

As shown in fig. 1, 2 and 3, the cartridge cleaning apparatus includes a housing 4, a rotary blowing device 3, an intake duct 2 and a dust suction duct 5, the housing 4 having a cover which can be opened and closed, and when the cover is closed, a closed space can be formed inside the housing 4. The bottom of the box body 4 is provided with an interlayer 9 formed by an upper box bottom 8 and a lower box bottom 6, the dust suction pipe 5 is a flat pipe and is arranged on the box body 4 and communicated with the interlayer 9, the outer end of the dust suction pipe 5 is provided with a butterfly valve, and the upper box bottom 8 is provided with a dust suction hole 1 communicated with the interlayer 9.

The rotary blowing device 3 comprises a central air pipe 32, an air nozzle 31, a rotating platform 37, a filter cartridge positioning frame 33 and a driving air pipe 35, wherein the upper end of the central air pipe 32 is closed, and the central air pipe is vertically fixed on the upper box bottom 8 through the lower end and is positioned in the center of the rotating platform 37. The air nozzles 31 are F-shaped nozzles, each air nozzle 31 is provided with forty-eight jet holes which are vertically arranged on the central air pipe 32, and the air nozzles are arranged on two sides of the central air pipe 32 at intervals in a staggered mode and communicated with the central air pipe 32, so that the filter cartridges are stressed in a balanced mode in the compressed air flow blowing process and cannot shake.
