Abstract
A turning and back-blowing device for a back-blowing bag filter relates to a turning and back-blowing device on a back-blowing bag dust cleaner. The existing valves all have the wind leakage problem. Because the filter bag frequently suffers the impact of the compressed air pressure (high pressure from zero point five to zero point eight MPa; low pressure from zero point two to zero point three five MPa), the service life of the filter bag is greatly shortened. The components of the product include a dust cleaner shell (7); the side surface of the shell is provided with a turning and blocking valve (1); an arc-surface dividing cam mechanism (2) is arranged on the shell; the middle part of the shell is provided with a support holding wheel group; an adjustable floating interface (4) is arranged below lower part of the shell; the lower part of the shell is a dividing annular wind cylinder (5); the bottom of the shell is provided with a division chamber cover (6) of the filter bag. The produce is used as a bypass valve on a bag dust cleaner.
Description
Technical field:
The utility model relates to the rotary counter-blowing mechanism on a kind of sack cleaner of back flushing type.
Background technology:
At present, the coal-fired both at home and abroad rotary counter-blowing sack cleaner that uses is used comparatively general, and its shape mostly is cylindrical shape, and filter bag mostly is flat bag pulse jet.It is effect by controller and magnetic valve (or pneumatic operated valve), the unbalanced pulse valve, having diameter on the pipe in winding-up is aperture about 6mm, osculum is over against the center of every filter bag, compressed air just in moment with the Venturi tube of very high speed by the sack place, simultaneously, injection together is blown into filter bag than the induced air of the big several times of own vol, filter bag is expanded suddenly, and cause the vibration of impact, make the dust on filter bag surface defeated and dispersed and come off, (high pressure 0.5～0.8MPa, low pressure 0.2～0.35MPa) causes life of bag filter to reduce greatly because filter bag frequently is compressed the impact of air pressure.
Summary of the invention:
It is rational that the purpose of this utility model provides a kind of rotary counter-blowing mechanism design, makes the overall performance of blowback sack cleaner improve the rotary counter-blowing mechanism of blowback sack cleaner greatly.
The purpose of this utility model is achieved in that
The rotary counter-blowing mechanism of blowback sack cleaner, its composition comprises: deduster shell (7), described shell side is equipped with revolution stop valve (1), ferguson cam mechanism (2), described shell middle part is housed above the described shell is set with that supporting support roller group (3), described shell below are set with adjustable floating interface (4), described outer casing underpart is a distinguish annular air duct (5), and described outer casing bottom is equipped with filter bag and divides chamber cap (6).
The rotary counter-blowing mechanism of described blowback sack cleaner, the open and close type of belt drive of described revolution stop valve (1) is YE or cam drive.
The rotary counter-blowing mechanism of described blowback sack cleaner, the calibration off-position number of described indexing cam mechanism (2) is 11 or 17 off-positions.
This technical scheme has following beneficial effect:
1. in order to improve the service life of filter bag, the designer has carried out structural adjustment to the filter bag ash removal principle, utilizes air-introduced machine outlet flue gas after being purified to carry out swinging locellus location reverse gas cleaning.Thereby realize off-line utmost point low-pressure deashing, pressure only has 0.003MPa, ash-removal effect is good, filter bag keeps straight inactive state substantially, the dust at filter bag surface and staubosphere interface is through the deashing variations in flow of filter bag, adhesion between staubosphere and the filter bag is dissolved, under the power that blows and gravity effect of the reverse deashing air-flow of staubosphere, vertical landing is to flue-dust retainer along filter bag surface, realized static gasification deashing, greatly reduce the degree of wear of filter bag, fatigue deformation degree and distortion number of times, the service life that can improve filter bag significantly.
2. this product has been realized the transmission mechanism of locellus, location, rotary counter-blowing.Because the reasonability of rotary counter-blowing mechanism design makes the overall performance of blowback sack cleaner improve greatly.
3. ferguson cam mechanism is adopted in the revolution location, can prevent cantilever turning barrel motion deformation.
4. this product operating frequency is low, rotates 1 time every 2 hours approximately, and rotate 1 circle is 6 minutes and 48 seconds at every turn, and the live load of (17 off-position) this product is low, and each rotating mechanism drives with 0.37Kw pinwheel speed-reducing cycloidal motor.The rotary part fit clearance of this product is moderate, not temperature distortion influence.Calibration, the off-position of this product are accurate, and the blowback behavior in service is reliable.
5. accurately motion is steady for the utility model circular index (11,17 two kinds) off-position, and power consumption is little, is the core technology of locellus, location blowback sack cleaner rotating mechanism.
