Description
Technical field
The utility model relates to a kind of thermal insulation apparatus, especially a kind of thermal insulation apparatus for three screw rod bitumenpumps.
Background technique
Insulation three screw pump is applicable to carry non-corrosiveness, not containing solid particle, the medium having coagulability at normal temperatures, be particularly useful for the occasion of extremely frigid zones outdoor mounted and the insulation of manufacturing process medium needs, medium temperature can reach 250 DEG C, viscosity is 5 ~ 1500cst.Heat carrying agent is mainly steam and conduction oil, is now widely used in the conveying of highway construction medium pitch.
At present, the thermal retardation form of state's inside holding three screw rod mainly contains in pump housing cylindrical welding insulation jacket, arrange incubation cavity, or the both ends of the surface of pump arranges incubation cavity bottom the pump housing; Above three kinds all exist certain defect: the first high insulating effect, but difficulty of processing is large, and welding procedure is complicated, inapplicable with production in enormous quantities; The second heat insulation effect is general, there is patent " insulation high viscosity triple screw pump ", incubation cavity is provided with bottom the pump housing, thermal insulation medium passage is provided with outside pump housing end, incubation cavity and thermal insulation medium passage are provided with several attachment holes, and wherein attachment hole needs follow-up boring, there is the risk of shutoff, and incubation cavity and thermal insulation medium passage separate, have thermal insulation medium not become the hidden danger in loop; The third heat insulation effect is better, there is patent " insulation three screw pump ", offer circular groove on the part at pump housing two ends, insulation closed-loop path is connected into by the intraparietal deep hole of pump between two circular grooves, this structural thermal insulation passage needs processing and gos deep into inside the pump housing, there is larger heat-conducting medium risk of leakage.
Summary of the invention
Technical problem to be solved in the utility model is to provide one and has high insulating effect, and technique is simple, the three screw pump of the thermal insulation apparatus that safety coefficient is high.
For this reason, the utility model is by the following technical solutions: it comprises the pump housing, be arranged on the driving screw in the pump housing and be engaged with driving screw two from screw rod, it is characterized in that described three screw pump also comprises thermal insulation apparatus, described thermal insulation apparatus comprises bottom incubation cavity, insulation flange and sidewall incubation cavity, described bottom incubation cavity is arranged on bottom the pump housing, described pump housing sidewall is provided with two or more insulation flange and sidewall incubation cavity, and sidewall incubation cavity is connected with bottom incubation cavity.
On the basis adopting above technological scheme, the utility model can also adopt following further scheme:
Described sidewall incubation cavity and bottom incubation cavity are welded with two or more insulation flanges, and one or more insulation flange is entrance insulation flange, and one or more insulation flange is outlet insulation flange.
Described insulation flange is distributed on incubation cavity arbitrary position.
Described sidewall incubation cavity can cover the whole of pump housing sidewall or local.
After have employed scheme of the present utility model, the sidewall incubation cavity in the utility model adopts sidewall Lower Half integral heat insulation, and insulation area of contact is large, high insulating effect.Sidewall incubation cavity adopts cast inblock or bottom weldering insulation iron plate technique to complete, and separate with pump housing active chamber, and position, connecting part all casts and forms, and avoids freeing of leakage.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
The utility model three screw pump structure is more close with traditional, mainly contain initiatively screw rod 1, bearing with round nut and initiatively screw rod stopping shim 12 locking is housed above, location and installation is on bearing support 4 together, bearing support 4 location and installation is on the pump housing 8, its middle pump body 8 is built with lining 7, and initiatively screw rod passes active screw rod lining 11 and cooperatively interacts with the driven screw 6 being contained in the inside, and two driven screw 6 afterbodys are equipped with driven screw lining 11 and driven screw stopping shim 10.Wherein driven screw 6 is positioned at driven screw lining 7 li by bearing support 4 and driven screw stopping shim 11.Bearing support 4 the other end is equipped with the sealing cover through active screw rod 1, between sealing cover 2 and active screw rod 1, mechanical seal 3 is housed, forms the seal space of pump together with the bonnet 13 that pump housing other end is installed.
Bottom the utility model three screw pump Novel heat preservation device mainly contains, incubation cavity 14, insulation flange 15, sidewall incubation cavity 16 form.One or more in insulation flange 15 is entrance insulation flange, thermal insulation medium enters one or two in sidewall incubation cavity 16 and bottom incubation cavity 14 by insulation flange 15, then enter in remaining sidewall incubation cavity 16 and bottom incubation cavity 15 one or two, then flowed out by one or two outlet insulation flanges, form a loop, by heat transfer, the medium in pump chamber is incubated.Wherein, sidewall incubation cavity 16 and bottom incubation cavity 14 can be cast and also can be welded, and are directly connected between sidewall incubation cavity and bottom incubation cavity, and other operations such as need not to hole, technique is simple.
Sidewall incubation cavity 16 is distributed in outside pump housing both sides, can all or local, and adopt sidewall integral heat insulation, insulation contact area rate " insulation high viscosity triple screw pump " is larger, and better heat preservation, adds upper bottom portion incubation cavity, and further strengthening heat insulation effect will.
Sidewall incubation cavity 16 comparatively " insulation high viscosity triple screw pump " is optimized, and is directly connected with bottom incubation cavity, and passage is directly cast and to be formed and roomy, prevents the blocking of insulation loop.
Although the utility model has illustrated by reference to preferred embodiment and has described, those skilled in the art should understand, and in the scope of claims, can do the various change in form and details.
