Abstract
The utility model discloses a wood fiber dust collection device comprising a feed inlet, a dust collection passage, a spray nozzle and settling chambers, wherein the dust collection passage is connected with the feed inlet; the spray nozzle is arranged in the dust collection passage; the settling chambers are connected with an outlet of the dust collection passage. The spray nozzle arranged on the wood fiber dust collection device moisturizes gas exhausted by a cyclone separator so that wood fibers automatically settle into a settling pond after being moisturized, the wood fibers which are separated and drained by the cyclone separator are collected, and thus the influence on the surrounding environment is reduced and meanwhile the collected wood fibers can be recycled; as a sewage filtering sand pit is formed, an outlet pipeline is arranged below the sewage filtering sand pit and connected with a water pond, the content of water in the settling process and the content of water in the wood fibers can be filtered and then collected so as to achieve the purpose of recycling the water; as at least two settling chambers are arranged, the recovery rate of the wood fibers can be increased.
Description
Technical field
The utility model relates to the drying, dedusting equipment of wood fibre in medium density fibre board (MDF) production process, is specifically related to a kind of wood fibre dust arrester, and this device is mainly used in wood fibre board and adopts the dedusting after 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 air delivery pipe heat drying, it is interior after the time heat drying in approximately 5 seconds that hot blast and fiber pulp are blended in pipeline, cyclone separator by 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) is along with air-flow is 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 5 microns of following particles are just along with air-flow has floated towards atmosphere, caused certain pollution not only to environment around, simultaneously also moulding the unnecessary waste of fiber.
Utility model content
Collect for the gas of getting rid of after cyclone separator is separated, wood fibre is separated and collected, the utility model provides a kind of wood fibre dust arrester.
In order to reach above-mentioned technique effect, the utility model is taked following technical scheme:
A kind of wood fibre dust arrester, comprising: charging aperture; Dedusting passage, is connected with charging aperture; Waterfog head, described waterfog head is arranged in 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 described husky pond of 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, separates with the first dividing plate and second partition, and the below of the first dividing plate is provided with opening, and the top of second partition is provided with opening.
The utility model compared with prior art, has following beneficial effect:
(1) this device be provided with waterfog head to cyclone separator discharge gas carry 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 will after the moisture filter in the moisture in infall process and wood fibre, collect, and reaches the recycling of water.
(3) this device is provided with at least 2 expansion chambers, can improve the rate of recovery of wood fibre.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model wood fibre dust arrester.
The specific embodiment
Below in conjunction with drawings and Examples of the present utility model, the utility model is further elaborated, to make the technical solution of the utility model more clear, clear.
Fig. 1 shows the structural representation of the utility model wood fibre dust arrester, and as can be seen from the figure, 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, is connected with charging aperture 1; Waterfog head 3, is arranged in dedusting passage 2, and waterfog head 3 carries out moisteningly to entering into gas in dedusting passage 2, makes the wood fibre in gas wetting; Expansion chamber 4, is 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, separate with the first dividing plate 10 and second partition 11, 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 an embodiment of the present utility model, 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.Below the husky pond 5 of sewage water filtration, be provided with outlet conduit 9, 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.
