Figure 1 shows that the top view of counter 1, what had is characterized as oblong-shaped, and its two side is denoted as 5 and 5' respectively.
Can see that from cross sectional drawing 2 heating arrangement comprises that top layer wooden partition 2 and bottom wooden partition 3 together with vertical partition wall 15, have formed the bending-type passage.The materials that carrying is loaded and transported above the top layer wooden partition 2, as pitch etc. be, top layer wooden partition 2 is supported by the vertical partition wall 15 of several files, and this partition wall is arranged on the bottom wooden partition 3.Clearance envelope between above-mentioned top layer and bottom wooden partition 2 and 3 forms several curve tunnels, adds hot fluid in order to hold.Adding hot fluid can be produced by the burner section of unspecified gas or fuel oil, and injects flame or burning gases by import 6, directly enters curved pathway via short wooden partition 5' so that add hot fluid.Because curved pathway system partly is made of some backflows of embarking on journey, add hot fluid and be forced through top layer wooden partition whole contact surfaces below 2, burning gases are at last from the vertical pipe that connects curved pathway one (two) end or chimney 8 discharges, above-mentioned vertical pipe also can contact with the pitch that will heat, and it can extend to the vertex of counter.Vertical pipe or chimney 8 can contact with counter two side wall panels 5 or 5'.Waste gas after burning is by open top 7(Fig. 3) discharge it by chimney.
For saving the energy and obtaining the quicker fusing of pitch with regard to certain heat energy, the spy has adiabatic layer 10 in order to cover bottom wooden partition 3.
Height at the top layer wooden partition 2 of counter sidewall 5' is provided with the usefulness that outlet 4 aims at the liquefied mass unloading.Top layer wooden partition 2 is tilted slightly, will increase rate of debarkation, this moment export 4 form the bottom nadir.Learn that from Fig. 2 outlet 4 is positioned at the nadir of top layer wooden partition 2 hatchings 63, has shown " V " font structure forming from two inclined-planes that are symmetrical in bottom centre's axis.Described two inclined-planes are exactly partly formed by the 2' of top layer wooden partition 2 and 2'' two.See to draw all to be fore-and-aft tilt shape 11 (at the one side at outlet place, 4 position) by wooden partition 2, wooden partition 3 curved pathway that forms from Fig. 3.Gradient 11 and 12 can be combined in same counter, or has only one of them, and opening 4 is normally closed it (also not shown among the figure) with plug screw, also has only when material in the cabinet has heated to arrive and could open when point of liquefaction is prepared unloading.
Fig. 4 is another embodiment of heating curved pathway in the counter of the present invention, and wherein curved pathway system is made up of the return flow line 64' of 64, two its both sides of apportion of centre gangway.It is adjacent in its inlet 20 that centre gangway 64 comprises a combustion chamber 21 again, this combustion chamber 21 is made up of a cylindrical wall 21', the diameter of this cylindrical wall is equivalent to heat the top layer wooden partition 2 of curved pathway and bottom wooden partition 3 vertical distance between the two, considers then to guarantee that as for its length it is criterion with interior person that the flame of unspecified burner section can remain on combustion chamber 21.
Return flow line 64' end (a) be provided with more than 8 of vertical channel with reference to Fig. 4, the selected unshowned outlet of wanting to cooperate bin of its appropriate location, this outlet is arranged in the bin bottom usually.
Fig. 4 a is the embodiment similar to Fig. 4 of the present invention, has curved pathway only and makes an amendment slightly.At this, centre gangway 64 increases two return flow line 64'' again in addition between two return flow line 64'.Ingenious arrangement like this make add hot fluid passed chimney 8 enter around among the environment, chimney 8 is stood far apart facing each other near back wooden partition 5b and front wooden partition 5a, and the hot fluid that is produced by burner section passes through at preceding wooden partition place.
Fig. 5 is with diagram method representation counter 50 internal solid materials 52 continuous each stage liquefaction process.As stage a, except that leaving a little space 51, fill solid material 52 fully in the counter.Bin 50 is provided with heating duct 54, is three joint bung flange shape structures, is not always the case to e at each stage a of Fig. 5.
The stage b explanation begins to heat the phenomenon in the short time of back, has only very thin one deck 55 raw materials to liquefy.
Among the stage c, the liquefaction layer strengthens around the conduit 54, and thickness became very little and two 54 of parallel heating ducts had not liquefied partly.There is no mobilely to whole material piece 52 of this stage, still be close on each sidewall of bin.
After continuing heating, (stage d) also make 56 these partly melt, once be that 56 blocks 52 that partly supported begin to sink now, because solid material proportion big after than liquefaction.The down maneuver of this solid-state block has only has space 57 to occur when between block 52 and counter sidewall, and liquid material can pass the space and flow in block 52 tops just possible.
In stage e, block 52 has dipped, and liquefied mass layer 59 formed already at block 52 tops, but can often have the quite thick liquid object bed of material of a slice between conduit 54 and block 52 bottoms.
Fairly obvious, 54 distribute heats of conduit, owing to the absorption of block 52 reaches the liquefaction purpose, but these heat energy must pass through the liquefied mass of suitable thickness, as shown in FIG. 55 layers, it has but formed conduit 54 and block 52 thermal resistance that transmits of heat between the two.Though the heating bung flange of any arrangement is arranged in the bin, but the liquefaction efficiency of solid material is still low, need more multipotency source consumption, also to do the time than the farm labourer.
Fig. 6 is according to the present invention, liquefaction process with graphic technique explanation bin continuous each stage of 50 internal solid materials, as shown in FIG., a flat-top wooden partition 2 is arranged above heating arrangement 62, be readily appreciated that on the flat face or two sections surfaces that the inclined-plane synthesized its liquefaction answer symbolic animal of the birth year with.
P stage a understands from figure and loads solid material 52 in the bin 50, has only the top to leave a little space 51.
After the heating of expression short time, 52 of top layer wooden partition 2 and blocks form thin layer 60 in the stage b, a little gap also occurs between same block 52 and bin vertical sidewall, so form the passage that liquefied mass flows to block 52 tops.Because block 52 bottom surfaces system is evenly heating comprehensively, the liquid that is melted by aspect 60 bears the pressure of block 52 weight immediately, this pressure facilitates the existing slit of block 52 and bin vertical sidewall to be easy to produce rapidly space 57, cause more liquid materials to flow to block 52 tops by this space 57, and more and more many.
C, d, e show in each stage and continue between the period of heating, block 52 constantly dwindles, simultaneously the top layer wooden partition 2 that but always remains on heating arrangement of block 52 has fine heating power contact condition, causes the heat energy of wooden partition 2 to be transferred to block 52 most effectively based on good heating power contact.So, block 52 in bin 50, heat need with the time (setting of Fig. 6) will be more than Fig. 5 in the heating arrangement required time for short.
Such as do not break away from category of the present invention and groundwork, all belong to feasible for the ameliorative measure of any aspect of counter.For example adiabatic equipment not only can be contained in below the bottom wooden partition 3, also can be contained on the counter vertical sidewall.
Indication counter of the present invention system is with regard to ordinary skill, and the general constructor of materials institute takes in the drawing 13,14 to make longitudinal and transverse Section Design, is for providing counter with firm bottom, and square tube 16 also is same situation with sidewall 5.
