Abstract
The utility model discloses a movable electric heater used at the bottom of a vertical oil container. The electric heater is divided into an upper part and a lower part, and is provided with an electric heater lifting base plate; a box body is arranged above the base plate; a thermal insulating layer is fixedly arranged on the inner wall of the box body; a silicon carbide vertical pit furnace pipe made of a plurality of blocks is closely clung to the inner wall of the thermal insulating layer; from the thermal insulating layer, a wiring bar penetrates the upper end connected with the furnace pipe; a pagoda-shaped steel structure is fixedly arranged in the middle of a temperature field in the middle of the base plate; and a graphite packing is fixedly arranged at the top end of the thermal insulating layer. A concave-convex flare groove is preset on the inner surface of the silicon carbide vertical pit furnace pipe, and a high-temperature resistance belt is welded with the wiring belt and then is led out of the outer wall of the box body through a ceramic protective tube. The movable electric heater used at the bottom of a vertical oil container has the advantages of high power, rapid temperature rise, long service life, facilitation of lifting motion operation, and safe and reliable performance.
Description
Technical field:
The utility model relates to vertical oil vessel bottom and uses movable electric heater.
Background technology:
Vertical oil vessel bottom is mainly used in the vertical oil vessel of suspension bottom with movable electric heater and heats; Because of container inner medium needs outside heating on one side; And adopt the lamination cooling water pipe to cool off on one side around around the container; Therefore, container inner medium need heat from the bottom, and requires electric heater to have up-down, locomotive function.
At present, what oil vessel bottom electrical heater structure adopted is: the cast iron flat heating plate is installed at the cylindrical tube top, and a screw mandrel is installed in the middle of the cylindrical shell; Adopt and manually to screw up-down mode and make heating plate be attached at the container awl end to heat, arrange high-power heating plate at the limited area of container bottom, the excessive life-span of electric heater surface loading is extremely short to making; On the contrary, power is little again to making the container inner medium temperature not reach production requirement and can't produce, and manual lead screw top and cylindrical shell adopt Welding Structure; Owing to being heated screw mandrel, conducting to of heat afterwards expand; Therefore, very difficult during decline, increased labour intensity.
Summary of the invention:
For overcoming the defective of prior art; The purpose of the utility model is to provide a kind of vertical oil vessel bottom use movable electric heater, is the big quick heating of a kind of power, long service life, uses movable electric heater bottom lifting moving is easy and simple to handle, performance the is safe and reliable vertical oil vessel.
The utility model technical solution problem adopts following technical scheme:
Movable electric heater is used in vertical oil vessel bottom, and said electric heater is divided into upper and lower two parts, and electric heater up-down chassis is set; Above said chassis, casing is set; Said cabinet wall is installed with heat-insulation layer, and said heat-insulation layer inwall is close to the carborundum shaft furnace courage of being made up of polylith, and the wiring rod passes from said heat-insulation layer and draws the upper end that is connected on said flue; In the middle of the temperature field that is positioned at middle part, said chassis, be installed with pagoda shape steel structure, the top of said heat-insulation layer is installed with the graphite packing.
Vertically be preset with concavo-convex flared channels at said carborundum shaft furnace courage inner surface, be installed with the high temperature resistance band in the groove, said high temperature resistance band and the welding of said wiring rod are drawn cabinet exterior through ceramic pillar afterwards.
Compared with present technology, the beneficial effect of the utility model is embodied in:
1, the utility model electric heater adopts two parts composition up and down, and promptly bottom chassis is mainly realized up-down, the locomotive function of upper portion heater; The bottom is that the circular flat car of hand-hydraulic is the electric heater chassis; On the chassis, set firmly cylindrical box, the well formula electric heater on cabinet wall filling heat insulating wall top, and welding pagoda shape steel structure in the middle of the temperature ground; Reduce temperature field accumulation of heat volume; Promote the temperature fast rise, the adjusting of carborundum flue height specification and tongue and groove pitch has not only been satisfied the power in temperature field and has been arranged; And having guaranteed the safety coefficient of high temperature resistance band, the heat that resistive band sent is simultaneously absorbed by container inner medium fast.
2, heating does not have short circuit phenomenon.Resistive band is installed in the vertical flared channels of arranging of carborundum, has guaranteed the security and the stability of heating.
3, the heating surface loading is little, long service life.The vertical fluting of the height of carborundum flue and inner surface can be adjusted flue specification and tongue and groove pitch flexibly according to the power needs, has guaranteed the minimizing of maximization, surface loading of resistive band specification, has guaranteed the maximum service life (MSL) of heating.
4, simple operation reduces labour intensity, energy savings.Because bottom chassis is operated light for the control of hydraulic pressure third gear hoists, neutral, decline; High temperature resistant graphite packing is installed at the electric heater top, can be fine under the bottom chassis hydraulic operation carry out the temperature sealing with container bottom, reduces heat waste, and the space, temperature field is little in addition, therefore, and saves energy greatly.
Description of drawings:
Fig. 1 is the utility model master pseudosection; Fig. 2 is the utility model vertical view.
Label among the figure: 1 chassis, 2 casings, 3 heat-insulation layers, 4 carborundum shaft furnace courages, 5 wiring rod, 6 pagoda shape steel structures, 7 graphite packings.
Below pass through the specific embodiment, and combine accompanying drawing that the utility model is described further.
The specific embodiment:
Embodiment: referring to Fig. 1-2, movable electric heater is used in the vertical oil vessel bottom of present embodiment, and electric heater is divided into upper and lower two parts, and the bottom is that the circular flat car of hand-hydraulic is the electric heater chassis; Cylindrical box 2 is set above chassis 1; Casing 2 inwalls are installed with heat-insulation layer 3; Be close to the carborundum shaft furnace courage of being made up of polylith 4 at heat-insulation layer 3 inwalls, the vertically preset concavo-convex flared channels of carborundum shaft furnace courage 4 inner surfaces is installed with the high temperature resistance band in the groove; High temperature resistance band and 5 welding of wiring rod are drawn cabinet exterior through ceramic pillar afterwards.
In the middle of the temperature field that is positioned at the middle part, chassis, be installed with pagoda shape steel structure 6, the top of heat-insulation layer 3 is installed with graphite packing 7.
