Abstract

The utility model relates to a bursting and puffing device for digestion, which is used for a digestion procedure in the process of paper technology and is installed on an ejection pipe. The utility model is composed of a bursting machine and a puffing tank. After installed and used, the utility model can reduce the consumption of calcined soda and sodium sulfide, effectively reduces digestion time, enhances beating degree of rough pulp, can reduces electricity consumption, reduces rough slag, and has the advantages of few papermaking broken ends, high tensile strength, slender fibre, low viscosity, good drainage property, easy washing, and easy screening.

Description

The cooking blasting puffing apparatus

The utility model relates to a kind of blaster, on particularly a kind of cooking process that is applied in papermaking process, and is installed in cooking blasting puffing apparatus on the blow-off pipe.

The most of low temperature high speed cooking method that adopts of existing papermaking digesting technology, this method is that slurry is directly entered dump chest by blow-off pipe and spraying pot, alkali charge is up to about 13% like this, and the screenings amount is big, papermaking intensity is difficult to improve, production process Central Plains consumption of coal and making beating power consumption are all very high, and the long fiber of having to mix more than 10% as the need paper machine raising speed of a motor vehicle meets the demands.

The purpose of this utility model is: the characteristics of easily soaking into grass as raw material according to alkali lye, provide a kind of to reduce alkali charge, make boiling quick heating, temperature retention time weak point, reduce the chemical degradation of cellulose, hemicellulose, thereby improve the cooking blasting puffing apparatus of the yield of paper pulp.

The utility model is to realize like this, it is made up of blaster and Bulking tank two parts, the blaster outer wall is cylindrical, inwall presents two not symmetrical paraboloid cone bodies, the centre position of two not symmetrical paraboloid cone bodies has formed a columniform trunnion, one end of paraboloid cone body is import, the other end is outlet, the port of export docks Bulking tank outward, and side is provided with one and checks hand hole, in be provided with fixed mount, be connected with the shuttle shape tongue on the fixed mount, Bulking tank is the drum type cylindrical hollow, and the one end is connected with blaster, and the other end is provided with slurry outlet.

Now reaching embodiment in conjunction with the accompanying drawings further illustrates the utility model.

Fig. 1 is that the utility model is faced the structural profile schematic diagram.

As shown in Figure 1, the utility model is made up of blaster 1 and Bulking tank 2 two parts, the outer wall of blaster 1 is cylindrical, its two ends, left and right sides are respectively arranged with and connect valve orchid 3, the inwall of blaster 1 presents two not symmetrical paraboloid cone bodies 4,5, an end of 4 is import, an end of 5 is outlet, and 4,5 not symmetrical intermediate ends form a columniform trunnion 6, the port of export of paraboloid cone body 5 is by connecting valve blue 3 butt joint Bulking tank 2 mutually, a side is provided with one and checks hand hole 7 outside 5 the port of export, be provided with fixed mount 8 in it, check that hand hole 7 is used for checking the outlet slurry situation in the blaster 1, the centre position of fixed mount 8 is fixedly connected with shuttle shape tongue 10 by locking bolt 9, shuttle shape tongue 10 is fixedly installed on the exit of columniform trunnion 6, and perpendicular to the position of center line of trunnion 6, Bulking tank 2 is drum dress cylindrical hollow, its two ends, left and right sides are respectively equipped with slurry import 11 and outlet 12, material import 11 is also docked with the port of export of blaster 1 by connecting valve blue 3, and the outer wall end of slurry outlet 12 is provided with connection valve orchid 3 equally.

Advantage after the utility model is installed and used is: install and use after (1) can with amount of caustic soda by 13% drops to 10.5%; (2) the akali sulphide consumption drops to 2% by 3.5%; (3) effectively digestion time by General 4-6 hour, drop to 2.00-2.30 hour; (4) slightly starch beating degree by 18-20 ° of SR, bring up to 32-34 ° of SR can reach 36-42 ° of SR through the beating degree of not pulling an oar after the bleaching; (5) use beater During making beating, ton slurry power consumption reduces the 300-330 degree; (6) pulp sifting, thick slag reduces 80%; (7) Brown stock is of light color, and whiteness reaches 36.6%, and bleachability can reduce by 1%. In addition, copy the paper little breakage, The tensile strength height, fiber is elongated, and viscosity is low, and drainability is good, easily washing, easily screening, and peace Filling not employment operation easy to use just can realize.
