Technical field
The utility model relates to technical field of dust removal equipment, particularly a kind of semidry method sack cleaner ship type ash bucket.
Background technology
Refuse incinerator of circulating fluid bed is in operation and can produces a large amount of discharged gas fumes, containing a large amount of solid particles in these flue gases, if these solid particles directly enter air, serious pollution can be caused to environment, thus effectively must process discharged gas fume.At present mainly semidry method is adopted to the process of boiler smoke, semidry method is exactly the method utilizing lime white to absorb poisonous harmful constituent in tail gas absorber, flue gas after absorption is again via sack cleaner filtration treatment, the dust filtered down then can fall in ash bucket, and then collects the dust in ash bucket.Ash bucket in existing sack cleaner mostly is ship type ash bucket, it is simple that it has structure, dust convergence property is convenient to well the feature of discharging, but anyly contribute to the facility that dust collects process owing to not having in ash bucket, thus cause the ashing capacity of existing ash bucket to still have certain deficiency, there is the necessity made improvements.
Utility model content
In view of this, the utility model is intended to propose a kind of semidry method sack cleaner ship type ash bucket, can improve the ashing capacity of ash bucket.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of semidry method sack cleaner ship type ash bucket, comprise the ash bucket housing in ship type be arranged at bottom cloth envelop collector, air inlet pipe is connected with at ash bucket housing upper, blast pipe is provided with at cloth envelop collector top, be connected with spiral dust in the bottom of ash bucket housing and discharge machine, the drive rod that can reciprocatingly slide along ash bucket shell length direction is provided with in described ash bucket housing, described drive rod orders about slip by the drive unit be located at outside ash bucket housing, the one end being positioned at ash bucket housing at described drive rod is also connected with the scraper plate be connected in the ash bucket inner walls of both sides.
Further, described drive rod is provided with tooth bar along its length, described drive unit comprises drive motors, and is connected to described drive motors drive end and the gear be meshed with the tooth bar on described drive rod.
Further, the ash hole of discharging machine at described spiral dust is provided with type heavy-hammer type air-locking flap valve.
Further, be provided with in the outside of described ash bucket housing the vibrating mechanism that periodically knocks is carried out to described ash bucket housing.
Further, described vibrating mechanism comprises the vibrating motor being arranged on cloth envelop collector place, and to be installed on described driven by vibrating motors end and to be placed in the pendulum at described ash bucket housing place.
Relative to prior art, the utility model has following advantage:
This semidry method sack cleaner ship type ash bucket, by arranging by the scraper plate of drive rod brought into motion in ash bucket housing, scraper plate is utilized continuously to scrape the dust that ash bucket inner walls adheres to, thus can make to be entered as much as possible in spiral dust discharge machine by the dust under cloth envelop collector filter, improve the ashing capacity of ash bucket.Drive rod arranges tooth bar, and makes drive unit be the drive motors installing gear, the overall structure of drive rod and drive unit can be made more simple, be convenient to design and implement.The ash hole of discharging machine at spiral dust arranges type heavy-hammer type air-locking flap valve, can to keep in ash bucket and blast stable in sack cleaner.The vibrating mechanism arranged outside ash bucket housing it carries out periodically knocking can ensure that the dust on ash bucket inwall falls in spiral dust discharge machine further.And vibrating mechanism is made up of motor and the pendulum be installed on motor, the structure of vibrating mechanism can be simplified, be convenient to manufacture and design and installation and maintenance.

Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
The present embodiment relates to a kind of semidry method sack cleaner ship type ash bucket, as shown in fig. 1, it comprises the cloth envelop collector housing 1 of hollow, multiple cloth envelop collector 5 is provided with in cloth envelop collector housing 1, be provided with the ash bucket housing 2 in ship type in the bottom of cloth envelop collector 5, ash bucket housing 2 is connected on cloth envelop collector housing 1.Air inlet pipe 3 is connected with on ash bucket housing 2 top, blast pipe 4 is provided with at the top of cloth envelop collector housing 1, be connected with spiral dust in the bottom of ash bucket housing 2 and discharge machine 6, in ash bucket housing 1, be provided with the drive rod 8 that can reciprocatingly slide along the length direction of ash bucket housing 2.Drive rod 8 orders about slip by the drive unit 9 be located at outside ash bucket housing 2, and the one end being positioned at ash bucket housing 2 at drive rod 8 is also connected with the scraper plate 7 be connected on ash bucket housing 2 inwall of both sides.
On drive rod 8, be provided with tooth bar along its length in the present embodiment, drive unit 9 then comprises drive motors, and is connected to the drive end of this drive motors and the gear be meshed with the tooth bar on drive rod 8.Namely reciprocatingly sliding of drive rod 8 realized by the positive and negative rotation of drive motors, certainly except adopting the mode of rack and pinion engagement, in the present embodiment, drive rod 8 also can be set to screw rod, adopts the version of ball-screw to carry out transmission between drive unit 9 and drive rod 8.For keeping in ash bucket housing 2 and sack cleaner 5 place blast stable in the present embodiment, the ash hole of discharging machine 6 at spiral dust is also provided with type heavy-hammer type air-locking flap valve 10.
Dust for ensureing further on ash bucket housing 2 inwall in the present embodiment falls into spiral dust and discharges in machine 6, is provided with carries out to ash bucket housing 2 vibrating mechanism that periodically knocks in the outside of institute's ash bucket housing 2.This vibrating mechanism can by the vibrating motor 11 being arranged on cloth envelop collector housing 1, and on the drive end being installed on vibrating motor 11 and the pendulum 12 being placed in ash bucket housing 2 place form.Certainly except adopting vibration motor 11 to drive pendulum 12 to carry out the version of knocking, vibrating mechanism also can adopt the existing vibration percussion structures such as the weight being ordered about swing by air pressure.
This semidry method sack cleaner ship type ash bucket, by arranging by the scraper plate 7 of drive rod 8 brought into motion in ash bucket housing 2, scraper plate 7 is utilized continuously to scrape the dust that ash bucket housing 2 inwall adheres to, thus the dust under can making to be filtered by cloth envelop collector 5 enters spiral dust as much as possible discharges in machine 6, improve the ashing capacity of ash bucket, carrying out in order of semidry method dust collecting process process can be ensured.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
