Abstract
The utility model relates to a paper pulp discharging pipe used in cellulose acetate cigarette filter tow production. The paper pulp discharging pipe is characterized by comprising a copper joint and a cylindrical paper pulp discharging pipe, wherein the copper joint is provided with a pulp channel; the cylindrical paper pulp discharging pipe is in interference fit with the outer surface of the copper joint and is provided with a smooth surface; and the paper pulp discharging pipe is sleeved on the copper joint. During pulp discharging operation, the paper pulp discharging pipe provided by the utility model is convenient to operate during copper joint replacement, not easy to generate statics and safer under a working environment containing acetone gas and has the effects of avoiding pulp reverse climbing, reducing the dismounting times of the copper joint and the replacing times of a metering pump, greatly increasing the work efficiency, reducing the washing times and the damage rates of the copper joint and the metering pump, greatly reducing the production cost and avoiding possibly-formed potential safety hazards caused by the fact that the pulp reversely climbs to a perforated plate.
Description
Technical field
The utility model relates to a kind of papery discharge pipe for Celluloseacetate cigarette filter tow production.
Background technology
During Celluloseacetate cigarette filter tow is produced, Cellulose diacetate flake is after acetone solution, filtration, make the raw slurry that tow is produced, slurries are white, thickness, high temperature, inflammable liquid, contain acetone, the acetone gas that volatilizees under the high temperature and air can form explosive mixture, when airborne acetone concentration arrives LEL (2.5-13) %LEL, can produce blast when meeting naked light or static.Slurries are through the moulding of spinneret cap spray silk, and spinneret cap selects different hole counts and aperture to arrange in pairs or groups, because the aperture is micron order unit, thereby the quality of the slurries by spinneret cap had higher requirement.
Enabling spinneret cap item for subsequent use or shutting down in the situation of the regular jobs such as the rear start of maintenance, the ducted slurries of slurries before the spinneret cap are not owing to flowing for a long time, the acetone of slurries, the volatilization of moisture content easily cause the dry and hard blocking channel of slurries in the preheater, damage measuring pump; Also having a kind of situation is that percentage of admixture is high or change the dope filtration device in the slurries, need to recycle after the underproof slurries discharging; And a tow production line is comprised of 20 to 40 spinneret cap items, thereby each spinneret cap item is carried out blowing is important routine work during tow is produced.Because the single thread that each spinneret cap item forms, high temperature air Celsius 90 ℃ high velocity stream overmolding from top to bottom in the path, so that contain the acetone of higher concentration in the hot-air, therefore blowing is not only requisite operation in the tow production, also is the operation that security risk is high, loaded down with trivial details and labour intensity is large.
Spinneret cap item blowing is with after the plug dismounting before, with laitance coating and the lumps on the cleansing pin cleaning copper sleeve, with cleansing pin dredging copper sleeve slurry channels, then can close measuring pump and carry out the blowing operation again.
Because the characteristic of slurries self utmost point thickness, copper sleeve slurries outlet outer surface is helicitic texture, the rough slurries that make of outer surface are attached to upwards counter climbing of flank, add in the path temperature higher, after slurries flow out from copper sleeve, the contained acetone of slurry surface volatilizees rapidly, at this moment rare parcel in the exit of copper sleeve tends to form outer the doing of a larger silkworm chrysalis shape.Because slurries are constantly discharged from the copper sleeve exit, again constantly volatilization of acetone under the hot environment, the surface of parcel is more and more harder, more and more thicker, cause parcel the inside pressure constantly to rise, at this moment the slurries of the inside will random all directions seeking breakthrough from this parcel, because it is higher that copper sleeve approaches the local general slurry temperature of outlet, the slurry surface of parcel is also relatively rarer, so just so that the new slurries that flow out in the inside are often outstanding from this position, forms new parcel.New parcel constantly up forms, the slurries of parcel the inside also can be constantly counter climbing up, will encase the copper sleeve most surfaces after a period of time at blowing like this.Beginning to wipe cap after blowing finishes goes to toward the cleaning copper sleeve that need to waste time and energy.
In addition on the one hand, in start or wage reform need to increase than multiple location the time, often because workload is larger, be short of hands, the phenomenon that foregoing copper sleeve is wrapped up by slurries has all appearred in a large amount of positions, path, so just cause cleaning difficulty, inefficiency, workload to increase etc. a series of reaction, for ensureing the blowing quality, avoiding that slurries are counter climbs, general 1 people can carry out simultaneously blowing to 8-10 item at most and operate.Use the earliest the discharge pipe of irony, copper or aluminium matter, take away for guaranteeing the slurries that discharge pipe is not flowed, discharge pipe need to have certain interference fit with connecting of copper sleeve, thereby can cause certain damage to the copper sleeve screw thread of blowing mouth, and also there are the problems such as cost is high, recovery is difficult in metal discharge pipe; Used again afterwards the plastics discharge pipe instead, and can easily form static because slurries flow at frosting, at this special high temperature in path and contain to use under the environment of acetone gas and have again danger, thereby the plastics discharge pipe is infeasible.
The utility model content
The purpose of this utility model provides a kind of papery guiding device--papery discharge pipe when producing blowing for Celluloseacetate cigarette filter tow.
In order to increase work efficiency, to reduce labour intensity, reducing the operation of changing copper sleeve, the utility model solves problem with discharge pipe.Concrete technical scheme is: the papery discharge pipe that is used for Celluloseacetate cigarette filter tow production is by with the copper sleeve of slurry channels, form with copper sleeve outer surface interference fit, columniform, ganoid papery discharge pipe, and the papery discharge pipe is enclosed within on the copper sleeve.
Papery discharge pipe of the present utility model has avoided that slurries are counter climbs when blowing operates, and it is easy to operate to change copper sleeve, can also reduce the dismounting of copper sleeve, the replacing of measuring pump, has improved greatly operating efficiency; Also protect simultaneously the copper sleeve screw thread, reduce cleaning and the damage of copper sleeve and measuring pump, greatly reduce production costs; The most important thing is that paper material is that natural fabric is not easy to produce static, containing usage comparison safety under the working environment of acetone gas, the anti-potential safety hazard of bringing to equal wind orifice plate of climbing of the slurries that can avoid in addition manpower may form not.
Description of drawings
Fig. 1 is papery discharge pipe structural representation of the present utility model.
Among the figure, 1-slurries, 2-papery discharge pipe, 3-copper sleeve slurry channels, 4-copper sleeve, 5-slurries preheater.
Specific implementation method
Papery discharge pipe of the present utility model by with the copper sleeve 4 of slurry channels 3, with copper sleeve outer surface interference fit, columniform, ganoid papery discharge pipe 2 forms, the papery discharge pipe is enclosed within on the copper sleeve.
Slurries 1 out flow out through copper sleeve slurry channels 3 downwards from slurries preheater 5, because the inside and outside surperficial smoother of papery discharge pipe 2, slurries are not easy to adhere to its outer surface, can flow out very smoothly, can instead not climb, use rear 1 people to carry out simultaneously the blowing operation to 30-35 item, work efficiency improves nearly 3 times.
