Abstract
The utility model provides a drying box for handsheet hot air drying in a laboratory. The drying box comprises a box body, wherein an air inlet is formed in the bottom of the box body, and an exhaust fan is formed at the top of the box body; a heating coil is installed on the lower portion inside the box body and close to the air inlet, and supporting networks used for placing a wet paper web are installed in the middle of the box body. The drying box mainly resolves the problem that hot air transmission type drying of the wet paper web in actual production cannot be simulated in the laboratory, provides a new process for the handsheet hot air drying in the laboratory, and meets the requirement that special performance is given to paper through changing of a drying mode in the field of specialty paper development. According to the drying box, the heating coil is arranged on the air inlet, when the wet paper web is formed on a sheet-making device and processed through squeezing and other processes, the wet paper web is placed on the supporting networks of the drying box, an air source produced by an air blower is heated through the heating coil, hot air transmits the wet paper web from bottom to top, and a drying purpose is realized.
Description
Technical field
The utility model belongs to pulp technology for making paper, relates to a kind of drying box, particularly a kind of laboratory drying box of heated-air drying handsheet.
Technical background
Drying box mainly is the equipment of dry write by hand wet web in the pulping and paper-making laboratory.To transfer at the wet web of moulding on the handshcet former and support on net or the supporting spring circle cloth, the paper web after handling through squeezing or other modes needs guarantee into the paper mass dryness fraction more than 90% by last high temperature drying dehydration after reaching certain mass dryness fraction.Existing drying mode generally comprises baking steel drying, heating, vacuum drying etc., but because some speciality paper in use needs to satisfy some properties, as high strength, high liquid-absorbing, high porosity etc., traditional drying mode can not be given into these additional properties of paper, need to select the technology of heated-air drying, and the equipment of the heated-air drying handsheet of the lab design of still doing nothing at present can't satisfy simulation industrial production speciality paper heated-air drying technology in the laboratory.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, the drying box of a kind of laboratory with the heated-air drying handsheet is provided, this drying box can give speciality paper some property by heated-air drying, possibility is provided for the technology of simulation industrial production speciality paper heated-air drying in the laboratory.
For achieving the above object, the utility model adopts following technical scheme: comprise that the bottom has the casing that air inlet, top offer ventilating fan; Nearly air inlet place, described box house below is equipped with heater coil, and the casing middle part is equipped with for the supporting network of placing wet web.
Above-mentioned air inlet is externally connected to the air blast that wind regime is provided.
Above-mentioned heater coil is connected with the temperature controller for the control hot blast temperature.
Above-mentioned heater coil also is connected be used to the motor that electric current is provided.
Above-mentioned temperature controller is installed on the cabinet exterior.
Be provided with two supporting networks that are used for clamping wet web in the above-mentioned casing.
Compared with prior art, the utlity model has following beneficial effect:
The utility model mainly is to solve the problem that can't simulate the hot-air through type dry wet paper web in the actual production in the laboratory, the new technology of a kind of laboratory with dry handsheet paper is provided, especially at the speciality paper development field, satisfied the requirement of giving the paper property by the change of drying mode.The utility model is provided with heater coil at the air inlet place, when wet web after moulding on the handshcet former, after squeezing or other PROCESS FOR TREATMENT, be positioned on the supporting network of drying box, after the wind regime that air blast produces heats through heater coil, hot blast penetrates wet web from bottom to top, reaches dry purpose.
Further, the utility model heater coil is connected with temperature control equipment, reaches the controllable purpose of hot blast temperature.
Further, the utility model arranges two supporting networks, and wet web is loaded between two supporting networks, after hot blast passes from the wet web bottom, discharges from the ventilating fan at casing top, makes wet web can not produce the fold phenomenon in dry run.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present utility model.
Wherein, 1 is air inlet; 2 is casing; 3 is heater coil; 4 is temperature controller; 5 is supporting network; 6 is ventilating fan.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Referring to Fig. 1, the utility model comprises that the bottom has the casing 2 that air inlet 1, top offer ventilating fan 6, and air inlet 1 is externally connected to the air blast that wind regime is provided; Nearly air inlet 1 place, described casing 2 inner belows is equipped with heater coil 3, and heater coil 3 is connected with the temperature controller 4 for the control hot blast temperature, and temperature controller 4 is installed on casing 2 outer walls; Heater coil 3 also is connected be used to the motor that electric current is provided in addition, is provided with two in the casing 2 and is used for placing the supporting network 5 that clamps wet web, and it is in order to prevent that wet web from producing fold in dry run that two supporting networks 5 are set.
The course of work of the present utility model is achieved in that
The utility model speciality paper development field has satisfied the requirement of giving the paper property by the change of drying mode.Heater coil is installed in the bottom in the drying box, and the wind regime that air blast produces heats rapidly through heater coil.Heater coil connects temperature controller, controls hot blast temperature by control heater coil exothermic temperature.After moisture process high temperature evaporation in the wet web and hot blast are taken away, make mass dryness fraction and other performances that paper reaches to be needed.
