Abstract
The invention discloses a dust removing device for wood fibers. The dust removing device comprises a feeding opening, a dust removing channel, a water spray nozzle and settling chambers, wherein the dust removing channel is connected with the feeding opening; the water spray nozzle is arranged in the dust removing channel; the settling chambers are connected with an outlet of the dust removing channel. The device is provided with the water spray nozzle for wetting gas discharged by a cyclone separator so that the wood fibers are naturally settled into the settling chambers after being wetted; the wood fibers separated and discharged by the cyclone separator are collected so that the influences on the surroundings are reduced and the collected wood fibers can be reused; a sewage filtering sand tank is arranged and a water outlet pipeline is arranged below the sewage filtering sand tank; the water outlet pipeline is connected with a water tank; water in the settling process and water in the wood fibers are filtered and collected so that the water can be reused; at least two settling chambers are arranged so as to improve the recycling rate of the wood fibers.
Description
Technical field
The present invention relates to the drying, dedusting equipment of wood fibre in the medium density fibre board (MDF) production process, be specifically related to a kind of wood fibre dust arrester, this device is mainly used in the dedusting after wood fibre board adopts the dry separation of cyclone separator.
Background technology
In the production technology of medium density fibre board (MDF), the wood fibre of middle density is by the air delivery pipe heat drying, hot blast and fiber pulp are blended in pipeline after the time heat drying in about 5 seconds, cyclone separator by the pipeline afterbody is separated fiber in pipeline and dry gas, cyclone separator is the centrifugal inertial force that utilizes the fibre-bearing γ-ray emission of rotation, a kind of dry type flow separation method that fiber is separated from air-flow, moisture (gaseous state) along with air-flow discharged to atmosphere, the fiber centrifugation sedimentation that proportion is heavier than gas.But cyclone separator can only defibre and admixture of gas in fiber or the particle of 93% left and right, remaining 7% diameter is that particle below 5 microns is just along with air-flow has floated towards atmosphere, environment around not only giving has caused certain pollution, simultaneously also moulding the unnecessary waste of fiber.
Summary of the invention
Collected for the gas of getting rid of after cyclone separator is separated, wood fibre is separated and collect, be the invention provides a kind of wood fibre dust arrester.
In order to reach above-mentioned technique effect, the present invention takes following technical scheme:
A kind of wood fibre dust arrester, comprising: charging aperture; The dedusting passage, be connected with charging aperture; Waterfog head, described waterfog head is arranged in the dedusting passage; Expansion chamber, expansion chamber is connected with the outlet of dedusting passage.
Further technical scheme is: described expansion chamber below is provided with the husky pond of sewage water filtration.
Further technical scheme is: the side of described expansion chamber is provided with at least one cleaning door.
Further technical scheme is: described waterfog head is connected with water pump, and the below of water pump is provided with pond.
Further technical scheme is: the below in the husky pond of described sewage water filtration is provided with outlet conduit, and described outlet conduit is connected with pond.
Further technical scheme is: described expansion chamber has 2 at least, between adjacent expansion chamber, with the first dividing plate and second partition, separates, and the below of the first dividing plate is provided with opening, and the top of second partition is provided with opening.
The present invention compared with prior art, has following beneficial effect:
(1) this device is provided with the gas that waterfog head discharges cyclone separator and carries out moistening, make the moistening rear automatic sedimentation of wood fibre to settling tank, cyclone separator is separated to the wood fibre of discharging to be collected, not only reduced the impact on surrounding environment, the wood fibre of simultaneously collecting can reuse.
(2) this device is provided with the husky pond of sewage water filtration, and the below in the husky pond of sewage water filtration is provided with outlet conduit, and outlet conduit is connected with pond, can, by collecting after the moisture in infall process and the moisture filter in wood fibre, reach the recycling of water.
(3) this device is provided with at least 2 expansion chambers, can improve the rate of recovery of wood fibre.
The accompanying drawing explanation
The structural representation that Fig. 1 is wood fibre dust arrester of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples of the present invention, the invention will be further elaborated, so that technical scheme of the present invention is more clear, understand.
Fig. 1 shows the structural representation of wood fibre dust arrester of the present invention, and as can be seen from the figure, the wood fibre dust arrester comprises charging aperture 1, and this charging aperture 1 is connected with the outlet of cyclone separator, collects isolated gas from cyclone separator; Dedusting passage 2, be connected with charging aperture 1; Waterfog head 3, be arranged in dedusting passage 2, and 3 pairs of waterfog heads enter into gases in dedusting passage 2 and carry out moisteningly, make the wood fibre in gas wetting; Expansion chamber 4, be connected with the outlet of dedusting passage 2, and the gas in dedusting passage 2 is after waterfog head 3 is moistening, and the moistening rear automatic sedimentation of wood fibre is in expansion chamber 4.
Better for the dust removing effects of assurance device, expansion chamber 4 has 2 at least.Between adjacent expansion chamber, with the first dividing plate 10 and second partition 11, separate, the below of the first dividing plate 10 is provided with opening, the top of second partition 11 is provided with opening, the gas of last expansion chamber passes through through the lower opening of the first dividing plate 10, then an expansion chamber after the opening of second partition 11 tops arrives.According to one embodiment of present invention, expansion chamber 4 is 2.
In above-mentioned device, waterfog head 3 is connected with water pump 7, and the below of water pump 7 is provided with pond 8.
To be deposited to moisture unnecessary in the wood fibre in expansion chamber and can to discharge in order to allow, the below of expansion chamber 4 is provided with the husky pond 5 of sewage water filtration, and the moisture that wood fibre can be filtered collect.Be provided with outlet conduit 9 below the husky pond 5 of sewage water filtration, outlet conduit 9 is connected with pond 8 simultaneously, and the water in the husky pond 5 of sewage water filtration can be recovered in pond 8 by outlet conduit 9 like this, realizes the recycling of water.
For the ease of the wood fibre in cleaning expansion chamber 4, the side of expansion chamber is provided with at least one cleaning door 6, and cleaning door 6 can be separately positioned on the not ipsilateral of expansion chamber 4, also can be arranged on the same side of expansion chamber 4.
