Abstract

The invention discloses a dust collector, aiming at providing a dust collector with low cost, small volume and good effect. The dust collector in the invention has the technical scheme as follows: a box plate is at least fixed with two groove-shaped dust collecting boards, gaps can be reserved between rows of dust collecting boards, two ends of a notch are respectively provided with an inward bend, and the notch faces against to an air inlet. At least two rows of the dust collecting boards are provided, the notch of the rear row dust collecting boards faces against the gap between the two dust collecting boards at the front row, the gap between two dust collecting boards at the rear row faces against the middle part of the dust collecting board at the front row, and a gap is arranged between the dust collecting boards respectively at the front row and the rear row. The dust colleting board is provided with a wave-shaped slot bottom. When the dust collector is arranged in a deduster, dust containing oil and dust with high moisture content can be effectively intercepted without adding a front-end device, thus ensuring normal operation of the deduster and having the advantages of low cost, small volume and good effect.

Description

Dust catching device

Technical field

The present invention relates to cleaner, particularly the dust catching device on the cleaner.

Background technology

When the oil-containing of dust, when water capacity is higher, as the dust water content up to 42%, relative air humidity is up to 95%, general sack cleaner can't be handled, because dust oil-containing, water capacity height cause the viscosity of dust to increase, dust is attached on the cloth bag, cause easily and stick with paste the bag phenomenon, winding-up was lost efficacy and was caused whole equipment failure cisco unity malfunction, and such phenomenon is too numerous to mention in industries such as chemical industry, tobacco, nonferrous metallurgy, fertilizer, cement.Have a lot of manufacturers to take interpolation equipment to do pre-process before dedusting workshop section to this problem, cause equipment cost to increase like this, steel consumption increases, and operating cost increases, and the land occupation area is big.

Summary of the invention

The purpose of this invention is to provide the dust catching device that a kind of cost is low, volume is little, effective.Technical solution of the present invention is done in such a way that dust catching device, it is characterized in that: be fixed with two flute profiles on the box plate at least and catch the dirt plate, in a row catching between the dirt plate is provided with the gap, and the notch two ends are equipped with inside bending, notch subtend air inlet.The described dirt plate of catching has two rows at least, and back row catches front-seat two gaps of catching between the dirt plate of notch subtend of dirt plate, and the middle part of dirt plate is caught at two subtend front rows, gap of catching between the dirt plate of row, back, and front and rear row is caught between the dirt plate and is provided with the gap.Described bottom land of catching the dirt plate is a waveform.The described dirt plate upper end of catching is provided with the air-vent of fixedlying connected with sealed nozzle.Described dust dust trapping device is located at the deduster the inside.Technique effect of the present invention is: when dust catching device is installed in the deduster the inside, need not increase preposition equipment and just can effectively tackle oil-containing, dust that water capacity is high, thereby can guarantee that deduster normally moves, have the advantage that adult is low, volume is little, effective.

Drawing explanation: 1, air inlet; 2, jet pipe; 3, nozzle; 4, the dirt plate is caught at the front row; 5, back row catches the dirt plate; 6, gas outlet; 7, box plate; 8, gap; 9, bottom land; 10, side plate; 11, bending; 12, notch; 13, flanging; 14, gap; 15, air-flow control and regulation valve; 16, high-pressure air source.

The specific embodiment

The present invention is described in more detail in conjunction with the accompanying drawings, the two ends that flute profile is caught dirt plate 4,5 are fixed on the box plate 7, back row catches front-seat two gaps 14 of catching between the dirt plate of notch subtend of dirt plate 5, bottom land 9 middle parts of dirt plate 4 are caught at two subtend front rows, gap of catching between the dirt plate of row, back, front and rear row is caught and is provided with gap 8 between the dirt plate, and the two ends of notch 12 are provided with inside bending 11, notch 12 subtend air inlets 1, catch bottom land 9 undulates of dirt plate, the upper end of catching the dirt plate is provided with the air-vent that communicates with nozzle 3.Because of this dust catching device volume is little, can directly dust catching device be installed in deduster the inside, need not add equipment oil-containing, dust air-flow that water capacity is high are made pre-process at the deduster front end; As shown in Figure 4, when oil-containing, dust air communication that water capacity is high are crossed air inlet 1, notch 12 enters into each and catches in the dirt plate, part dust air-flow hits bottom land 9, shunt to both sides by the centre along the waveform bottom land, hit side plate 10 again, hit the turn of bilge of bending 11 along side plate 10, along flanging 13 from catch come out in the dirt plate after, catch gap 14 between the dirt plate by the front row and enter into back row and catch in the dirt plate; Another part dust air-flow is caught gap 14 between the dirt plate and is directly entered into back row and catch in the dirt plate from the front row, oil-containing, the dust air-flow that water capacity is high pass through multiple impact in catching the dirt plate after, catch dust air-flow oil-containing, the water capacity that the dirt plate comes out from back row and obviously reduce, at this moment catch the low dust air-flow of oil-containing, water capacity that the dirt plate comes out and 6 enter into next dedusting program through the gas outlet from back row.When the dust air-flow that oil-containing, water capacity are low was filtered by the cloth bag interception, because of the dust water capacity is low, viscosity reduced greatly, is difficult for causing sticking with paste a bag phenomenon, has so just guaranteed the normal operation of deduster.

The operation principle of dust catching device is: because powder dust particle has size, the powder dust particle that varies in size has different quality, prop up moving because the powder dust particle that varies in size follows the streamline of air-flow, the big more oil-containing of powder dust particle, water capacity is high more, oil-containing, the high more weight of water capacity is heavy more, after powder dust particle is caught the dirt plate through multiple impact, the particle that weight is big is easy to be caught the dirt plate and traps, by the time the high-pressure spray sweeper was opened automatically when the dust catching amount in the dust catching device reached some, high pressure draught is by jet pipe 2, nozzle 3, air-vent enters each and catches in the dirt plate, disposes the dust of catching in the dirt plate.The high-pressure spray sweeper controls to adjust valve 15 etc. by high-pressure air source 16, jet pipe 2, nozzle 3, air-flow and forms.
