Abstract

The utility model discloses a melting kettle steam heating system used in rosin production. The heating system comprises a main steam inlet pipe arranged at the bottom of a melting kettle and below a filtering plate, and an auxiliary steam inlet pipe arranged on the lower middle part of the melting kettle and above the filtering plate, wherein the main steam inlet pipe is an annular pipe surrounding the wall of the kettle; the auxiliary steam inlet pipe surrounds the wall of the kettle; air outlets which are uniformly formed on the inner annular pipe surface of a body of the auxiliary steam inlet pipe at intervals; the air outlets face the same side clockwise or anticlockwise at angles of 30 to 60 degrees on the horizontal plane; and three adjacent air outlets form a group and are respectively formed in the middle, on the lower middle part and on the lower part of the inner annular pipe surface. By the heating system, an auxiliary heating system is additionally arranged, and besides the conventional mode of heating rosin liquid by rolling rosin liquid up and down, a mode of heating the rosin liquid by rotating the rosin liquid is adopted, so that the heating area of the rosin liquid and the heating speed are increased, and a solubility property is enhanced.

Description

Rosin production is with fusion still steam-heating system

(1) technical field:

The utility model relates to chemical industry equipment, is specially a kind of rosin production with fusion still steam-heating system.

(2) background technology:

Primary operation in the rosin production process is the fusion of rosin, and rosin is squeezed into feed hopper with conveying worm by holding the fat pond, gets into fusion still continuously through screw(-type) feeder.Rosin is thickness and have the semifluid of certain moisture content and impurity, for ease of removing impurity, need add a certain amount of turpentine oil and water during the rosin fusion.Rosin is the heating fusion in the fusion still; Temperature is controlled at 90 degree～95 degree; Turpentine oil that is evaporated in the fusion processes and water vapour are reclaimed by the condenser on fusion still top, and discharging to high-order pot descended fat liquid to make operation only after the filter of fusion fat liquid in the fusion still removed thick impurity.

Rosin fusion heating means commonly used are to feed steam to the fusion still; Steam is sent in the fusion still by jet chimney and directly rosin is heated; Said jet chimney is a ring-type, and is located at the bottom of fusion still, and rosin is upper and lower after being heated rolls; Heat constantly upwards transmits from the bottom, up to the rosin in the whole fusion still is heated into fat liquid.

The weak point place of said traditional heating system: heat inhomogeneously, heat time heating time is long, influences manufacturing schedule.

(3) utility model content:

To the weak point of traditional heating system, the purpose of the utility model is that a kind of rosin production that improves heating environment, improves the thermal efficiency of design is with fusion still steam-heating system.

The rosin production that can realize above-mentioned purpose is with fusion still steam-heating system; Comprise the steam master air inlet pipe of being located at fusion still bottom, filter below, the ring pipe of said steam master air inlet pipe for being provided with around the still wall, different is also to comprise the steam auxiliary inlet manifold of being located at fusion still middle and lower part, filter top; Said steam auxiliary inlet manifold is provided with around the still wall; Offer evenly spaced gas outlet on its body, by clockwise or counter-clockwise direction deflection the same side, the steam auxiliary inlet manifold is when feeding steam in horizontal plane for said each gas outlet direction; The steam promotion fat liquid of ejection rotatablely moves from the gas outlet; Cooperate the tumbling motion up and down of fat liquid, help the fusion of fat liquid, reduce the fusion time.

Promote the effect that fat liquid rotates for improving, said each gas outlet is opened on the interior endless tube face of steam auxiliary inlet manifold body.

Said each gas outlet direction and the drift angle that radially becomes 30 degree～60 degree.

Said each gas outlet direction is 45 degree with the preferred drift angle that radially forms.

For making fat liquid temperature in the Steam Heating process even, can adjacent three gas outlets be compiled is one group, and three gas outlets are offered respectively at the centre position of the interior endless tube face of steam auxiliary inlet manifold body, middle upper/lower positions and lower position.

The advantage of the utility model:

The production of the utility model rosin is with fusing the still steam-heating system owing to increased auxiliary heating system; Except that former heating system makes the mode of heating that fat liquid rolls up and down; Also increased the rotary type mode of heating that makes the rotation of fat liquid; Increase the heating surface area of fat liquid, improved firing rate, increased solubility property.

(5) specific embodiment:

Be described further below in conjunction with the technical scheme of accompanying drawing the utility model:

The production of the utility model rosin is made up of steam master air inlet pipe 6 and steam auxiliary inlet manifold 1 with fusion still steam-heating system.

Said fusion still 2 usefulness supports 8 support, and fusion still 2 is a tank body, and the top of tank body and bottom are arch; Offer discharging opening in the tank body top center, discharge nozzle 12 gets into from top to bottom from discharging opening and fuses in the still 2, and arrives at fusion still 2 bottoms through filter 3 central through holes of fusion still 2 bottoms; The discharge nozzle 12 bottom mouths of pipe are angle, and the charging aperture 11 of fusion still 2 is opened in tank body top, and situation showed on trial 10 in the position that tank body top is lower than charging aperture 11 offered and observes jar; Thermometer 9 is located at the tank body middle part; Slag-drip opening 5 is opened in the tank body bottom corresponding to filter 3, and discharging force pipe 7 is opened in the tank body top with Pressure gauge 13, and is as shown in Figure 1.

Said steam master air inlet pipe 6 is lower than filter 3 and is arranged at fusion still 2 bottoms, and steam master air inlet pipe 6 becomes to go in ring around the still wall, offers the venthole that is directed upwardly on the last side pipe face of body; Said steam auxiliary inlet manifold 1 in fusion still 2 middle and lower part, be higher than filter 3 and be lower than thermometer 9 settings; Steam auxiliary inlet manifold 1 becomes to go in ring around the still wall; The even spaced apart gas outlet 4 of in horizontal plane, being partial to the same side in the direction of the clock that is provided with on the interior endless tube face of body; Said gas outlet 4 quantity are 12, like Fig. 1, Fig. 2, shown in Figure 3.
