Pulse backblowing filter element filtering fully automatic powder retracting device
Technical field:
The utility model belongs to the powder recovering device in a kind of electrostatic powder coating system, particularly a kind of pulse backblowing filter element filtering fully automatic powder retracting device.
Background technology:
Powder Recovery is divided into wet type and dry type two big classes according to the technology difference: the wet type Powder Recovery is when utilizing the air communication that has powder to cross liquid, reach the purpose that purifies air by the liquid adsorption powder particle, the powder of recovery could reuse after needing drying to handle.The dry type Powder Recovery is to allow the air communication that has powder cross certain method, and with gas, the solid separation, gas is cleaned the back and discharges, the powder recycling of being dammed to get off.The dry type Powder Recovery mainly contains cyclone separating and filtering type two big classes.The cyclone separating retracting device is that powder stream is rotatablely moved, and under action of centrifugal force, reaches the purpose of powder particle and flow separation.Structure difference according to the cyclone separating powder recovering device, its Powder Recovery rate generally can reach 80~90%, in order to reach environmental requirement, separates than the fine powder particle, guarantee the cleaning of exhaust jet stream, need increase the cascade filtration device in the discharge end of cyclone separating retracting device.The filtering type powder recovering device is that the powder air communication is crossed the filtering material that has certain micropore, reaches gas, solid purpose of separating, and stops up easily but shortcoming is a micropore in the filtering material, causes to reclaim air-flow and reduce, and recovering effect reduces.For overcoming this shortcoming, pulse backblowing formula filter has appearred, utilize the pulse backblowing periodic cleaning to be adsorbed on particle in the filtering material micropore, make air-flow keep the unimpeded constant recovering effect of keeping, size according to powder particle, select suitable material for core, its Powder Recovery rate generally can reach 98%.In the dry type powder recovering device, the powder of recovery has just been realized holding back, and also realizes reclaiming utilizing again automatically of powder, needs the labor cleaning to realize the utilization again of powder afterwards.
Summary of the invention:
The purpose of this utility model just is to overcome the above-mentioned existing middle deficiency that exists, and a kind of pulse backblowing filter element filtering fully automatic powder retracting device is provided, and this device can be finished the interior suspension of spray booth and the full-automatic recovery and the recycling of whereabouts powder automatically.
The technical solution of the utility model is: a kind of pulse backblowing filter element filtering fully automatic powder retracting device is characterized in that: by being arranged on indoor pulse backblowing filter core powder recovering device of Powder Recovery and swash plate vibration dust feeder, being arranged on the powder collection device of powder spraying chamber inner bottom part and the powder conveying device that communicates is with it formed; Filter communicates with powder spraying chamber, and the Powder Recovery chamber communicates with air-introduced machine.
Described swash plate vibration dust feeder is made up of vibrator and the swash plate that is installed on the vibrator.
Described powder collection device is the scraper plate powder catcher.
Described powder conveying device is made up of with the powder conveyor that is connected with auger the auger that is installed in the powder collection device bottom.
The utility model has the advantages that: use the automaticity that can improve the powder coating process behind this device, make the effective rate of utilization of powder can reach 98%, reduced the pollution of powder, greatly reduced the labour intensity of powder coating process, application labor productivity is significantly improved atmosphere.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
A kind of pulse backblowing filter element filtering fully automatic powder retracting device is made up of the pulse backblowing candle filter 2 and swash plate vibration dust feeder, the scraper plate powder catcher 4 that is arranged on powder spraying chamber 3 inner bottom parts and the powder conveying device that communicates with it that are arranged in the Powder Recovery chamber 1; The pulse backblowing candle filter communicates with powder spraying chamber, and the Powder Recovery chamber communicates with air-introduced machine 5.Described swash plate vibration dust feeder is made up of vibrator 6 and the swash plate 7 that is installed on the vibrator.Described powder conveying device is made up of with the powder conveyor 9 that is connected with auger the auger 8 that is installed in scraper plate powder collection device bottom.
The course of work of the present utility model is: collect suspended powder by filter with 11 work of spray gun 10 spraying workpiece the time, blowback regularly drops on the vibration swash plate recover powder, under the effect of gravity, be slipped to the bottom of powder spraying chamber, again by the scraper plate powder catcher with the powder scraping delivery of powder spraying chamber bottom to the auger place, with auger the powder unification is transported to powder conveyor, be transported to powder collector 12 with venturi pump again, the waste gas that powder collector produces is transported in the powder spraying chamber through exhaust piping, prevents that waste gas is excessive; The powder that powder collector separates is transported to powder feeder unit-fluid bed with qualified powder and reuses or boxing for later use for powder case 14 after vibratory sieve 13 screenings.
