Technical field
The present invention relates to a kind of filter cartridge type dedusting unit, specifically, relate to a kind of seamless steel pipe mill inwall filter cartridge type dedusting unit.
Background technology
The seamless steel pipe internal wall grinding, can be used for scale removal and allowance, emery wheel on the grinding machine is on inwall during grinding, can produce a large amount of dust, need to use deduster, a kind of heavy streaming multi-tube dust cleaner is disclosed in the utility model patent of patent No. ZL99228768.5, this deduster comprises dust-removing box, this dust-removing box offers air inlet and gas outlet at the top, be provided with the filter cylinder that many groups are obliquely installed in this dust-removing box, the air-flow that has a large amount of dust enters from air inlet, utilize gravity and descending air-flow to pass filter cylinder, dust in the gas is held back by filter cylinder, clean gas flow after the dedusting is sent from the gas outlet, in filter cylinder open end up back-blowing device is arranged, this back-blowing device is used for deashing, specifically, passes through back-blowing device, with compressed air filter cylinder is recoiled, remove the dust of holding back on the filter cylinder, dust falls to the bottom of dust-removing box in the effect of gravity, and this back-blowing device can adopt high pressure draught to jet, though air-flow is even, but air consumption is big, and this back-blowing device also can adopt air pulse to jet, though air consumption is little, but air-flow a little less than, the dust that may remove on the filter cylinder is not thorough.During grinding, emery wheel on the grinding machine is fixed on the mill bar, the feed that moves axially along steel pipe, steel pipe rotates on turning rolls, during rotation, steel pipe can produce axial displacement, departs from the air inlet of dust-removing box, the a large amount of dust that make grinding produce can't all enter the air inlet of dust-removing box, cause the exhaustion rate not high.
Summary of the invention
The purpose of this invention is to provide the seamless steel pipe mill inwall filter cartridge type dedusting unit that a kind of deashing is thorough, air consumption is little and the exhaustion rate is high.
For achieving the above object, the technical solution used in the present invention is: a kind of seamless steel pipe mill inwall filter cartridge type dedusting unit, comprise dust-removing box, offer air inlet and air outlet on the described dust-removing box, be provided with the filter cylinder that many groups are obliquely installed in the described dust-removing box, described dedusting unit also comprises from described filter cylinder openend up be blown into compressed-air actuated deashing device in described filter cylinder, be provided with the core pipe that extends along the length direction of described filter cylinder in the tube chamber of described filter cylinder, described core pipe termination is up sealed, between described filter cylinder and described core pipe, formed the deashing passage that flows for described compressed air, described dedusting unit also comprises the plenum chamber that has the gateway, the outlet of described plenum chamber is connected with described air inlet, and described seamless steel pipe stretches into the inlet of described plenum chamber.
Described core pipe termination up is outstanding forward with respect to described filter cylinder openend up, and the outstanding taper that is.
Length direction along described filter cylinder is provided with the aeroscopic plate that polylith is provided with separately between described filter cylinder and described core pipe.
Described deashing device comprise nozzle, with the gas tank that described nozzle links to each other, on the described filter cylinder openend up Venturi tube is installed, the inlet of described Venturi tube is over against described nozzle.
Described filter cartridge type dedusting unit also comprises bracing frame, and described casing is located on the support frame as described above, and a plurality of castors are equipped with in the bottom of support frame as described above.
Be provided with the baffle plate that protrudes towards this box house on the inwall of described dust-removing box, described baffle plate is facing to described air inlet.
Described core pipe and described filter cylinder same axis are provided with.
Described air inlet is positioned at the bottom of described dust-removing box, and described air outlet is positioned at the top of described dust-removing box, and described plenum chamber covers on the described air inlet.
Because the present invention has adopted above technical scheme, its advantage is as follows: owing to set up the core pipe in filter cylinder, then the compressed air that is blown into from deashing device can only pass through from the deashing passage between filter cylinder and the core pipe, therefore reduced the winding-up area in the filter cylinder, under the prerequisite of winding-up same traffic air, improved velocity of compressed air, make compressed air fully to contact with filter cylinder, thoroughly remove the dust of holding back on the filter cylinder, when reaching identical ash-removal effect, deduster of the present invention is littler than the deduster air consumption in the background technology; After the dust on the filter cylinder is thoroughly removed, can improve filtration velocity, thereby improve efficiency of dust collection.Seamless steel pipe stretches into the inlet of plenum chamber, can remedy the axial displacement that steel pipe produces by plenum chamber, like this after the grinding of steel pipe inwall produces a large amount of dust, the air-flow that has dust can all enter in the plenum chamber, prevent that dust from leaking, improve the exhaustion rate, plenum chamber can also reduce the speed of air-flow, the dust that particle is bigger in the air-flow can be deposited in the plenum chamber rough dusting in advance.
