Description
Technical field
The utility model relates to a kind of dust arrester, relates in particular to a kind of dust arrester that is used for the dedusting of tablet dressing production process.
Background technology
Can produce the dressing material dust of a large amount of water smoke shapes in the film-coated production process in tablet workshop, pharmaceutical factory, these dust state in process of production gradually becomes the solid shape and is sucked by dust removal machine from original semi-solid.Shown in the existing dust removal machine apparatus structure schematic diagram of Fig. 1, dust arrester is made of casing 1 ', blower fan 2 ' and nonwoven filter bag 3 ', the nearly blower fan 2 ' of casing locates to establish air inlet, the bottom sets out the air port, start after the blower fan, the air communication that contains dust is crossed air inlet and is entered casing 1 ', and dust is filtered out by nonwoven filter bag 3 ' when flowing through nonwoven filter bag 3 ', thereby reaches the purpose of dedusting.
But because the raw material of dressing has stronger viscosity, and its dust state changes in process of production, so soon filter bag is blocked.
About about 3.5 hours, the nonwoven filter bag was just blocked about 1.5 hours a collection of dressing process in the dust removal machine and have now, can't normally carry out thereby have influence on whole dressing process greatly in actual production.Therefore, have in 3.5 hours need to change 2 filter bags, greatly reduce the production efficiency of tablet thin-film process like this, and influence the quality of tablet film at a collection of dressing.Existing deduster has a large amount of dressing raw materials to be discharged among the air owing to filtration is undesirable.These raw materials are coloured, cause large-area coloured pollution.
Therefore, be necessary a kind of dust arrester newly developed, make it to be difficult for being stopped up, avoid the frequent filter bag of changing in tablet dressing process by dust.
Summary of the invention
The utility model dust arrester technical problem to be solved is, easily blocked and reduce the shortcoming of production efficiency at existing dust arrester, a kind of blocked dust arrester that is difficult for is provided, reduces the frequency of changing filter bag, thereby improve the production efficiency of tablet dressing greatly.
In order to solve the problems of the technologies described above, the utility model adopts following technical proposals: a kind of dust arrester, comprise casing, blower fan and nonwoven filter bag, one blower fan is set in the casing, one air inlet is set on the casing, one air outlet, powder dust fluids is discharged by air outlet after the nonwoven filter bag filters from air inlet, wherein, the air inlet upper horizontal is provided with two layers or more filtration stratum reticulare at interval in casing, and the cone that wall shrinks downwards around is set below the air inlet in casing, forms a cavity with the screen pack interlayer above cone, establish a dust at cone base and remove valve, establish a nonwoven filter bag at the air outlet place.
Basic design of the present utility model is to adopt to change air-flow velocity and the multiple tracks dedusting mechanism is set to carry out dedusting, its concrete operation principle is: start blower fan, when the air communication that contains dust is crossed air inlet and is entered casing, because of becoming ambassador's fluid velocity rapidly, the space slows down, and because the proportion of change of the flow direction of air-flow and wet dust is greater than the proportion of air, the wet dust that particle is bigger is deposited on the cone upper surface because of deadweight, the less wet dust of particle is along with air-flow upwards flows to the filtration stratum reticulare, because it is even to filter the density unevenness of velvet ball in the stratum reticulare on the one hand, can change the flow direction of air-flow, on the other hand, the less wet dust of particle also has viscosity, therefore, the less wet dust of particle is just attached to filtering on the stratum reticulare, littler dust is filtered out by the nylon screen pack when airflow passes nylon screen pack, minimum dust is filtered out by the nonwoven filter bag when flowing through the nonwoven filter bag, simultaneously, the about 40-50 of the temperature of air-flow ℃, can become dry attached to the wet dust of filtering on the stratum reticulare, in this section in the dust of Bian Ganing, oarse-grained dust can drop on the cone, short grained dust can be filtered when airflow passes nylon screen pack and nonwoven filter bag, thereby reach the purpose of abundant dedusting, and prolonged the replacement cycle of nonwoven filter bag.In addition, prove by experiment, adopt one deck to filter stratum reticulare and the phenomenon that the dressing material passes can occur, hinder and filter that not ideal, two layers of filtration stratum reticulare effect are better, three layer filtration stratum reticulare filter effect ideal.The effect that dust is removed valve is to be convenient to remove the dust of staying the cone upper surface.
On the such scheme basis,, establish air intake bend pipe crooked under the opening at described air inlet for further lowering the flow velocity that sucks powder dust fluids.
Be convenient cleaning, replacing of filtering stratum reticulare, the sidewall both sides correspondence of described casing is provided with the screen pack guide rail, filters stratum reticulare and is made up of velvet ball screen pack, and insert in this screen pack guide rail the two edges of this filtration stratum reticulare.
Clean for convenient, and improve the fastness of filtering stratum reticulare, described filtration stratum reticulare is made up of stainless steel wire bobbles screen pack.Main effect is to utilize the proportion of air and wet dust and viscosity not to coexist to hold back a large amount of wet dust in the higher velvet screen pack of density, utilize the irregular hole of stainless steel velvet constantly to increase resistance and its flow direction of change in addition again, improved interception result greatly.
On the technique scheme basis, owing to penetrate stainless steel wire bobbles screen pack with air-flow after becoming dry attached to the wet dust on the stainless steel wire bobbles screen pack in actual use, for this part is stopped from the dust that stainless steel wool ball screen pack comes off, described nonwoven filter bag air intake is provided with a nylon screen pack, and the mesh of nylon screen pack is 100 orders.
On the technique scheme basis, the caliber of the caliber of air intake bend pipe for amplifying.It is the flow velocity that can reduce air-flow behind the increase caliber that the air intake bend pipe adopts the effect of the caliber that amplifies, and is convenient to abundant Chalk-dust filtering.
On the technique scheme basis, clean the stainless steel wire bobbles for convenience and filter maintenance sealing in stratum reticulare and the work, the stainless steel wire bobbles filters and adds a cover a removable box sealing lid on the stratum reticulare.
On the technique scheme basis, the stainless steel wire bobbles is placed 60 to 140/square metre on the stainless steel wire bobbles screen pack, preferred 120/square metre.Pull out the stainless steel wire bobbles after every production 3-4 criticizes and filter stratum reticulare, water also can recover original filter effect after cleaning, and can use repeatedly.
The utlity model has following technological merit:
One, by changing powder dust fluids speed, improves filter effect;
Two, adopt stainless steel wire bobbles screen pack, nylon screen pack and nonwoven filter bag three road dedusting mechanisms, improve dust collection capacity greatly, and prevent that effectively filter bag from being stopped up by dust, reduce filter bag and change frequency, once reducing to continuous production 3-4 by original about 1.5 hours shutdown replacing filter bags criticizes, that is: promptly the working time is to change once in 10.5 hours to 14 hours, significantly improves the production efficiency of tablet dressing;
Three, be provided with removable box sealing lid, the cleaning and filtering layer is convenient.
Four, the utility model filter effect excellence does not have the contaminated environment that the dressing dust causes.
