Description

The superconducting heat collection follower

Technical field

The superconducting heat collection follower belongs to the warm-up mill apparatus field, is specifically related to a kind of superconducting heat collection follower that is widely used in industries such as papermaking, weaving, printing and dyeing and heating, drying.

Background technology

In industries such as papermaking, weaving, printing and dyeing, adopting steam boiler or thermo oil boiler mostly is heating source at present, is difficult to reach the above special process requirement of 200 degree, and environmental pollution, energy waste are serious, in the equipment running process, unsafe factor is more, has also strengthened labor strength simultaneously.Existing warm-up mill has overcome above-mentioned deficiency preferably by electrically heated mode, but heating tube is distributed in the hole on the roll body barrel or the whole roll body inner chamber that is applied in, and utilization rate is still lower like this, heats inhomogeneous; Calandria is fixing not firm, because warm-up mill rolls for a long time, calandria is impaired easily in using.

Summary of the invention

The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of simple in structure, superconducting heat collection follower that the thermal efficiency is high is provided.

The technical scheme that its technical problem that solves the utility model adopts is: this superconducting heat collection follower, comprise columnar roll body and calandria, the roll body two ends by flange seal and rotational support in the rotating shaft of both sides, the roll body barrel is provided with sealing and axially runs through the heat-conducting medium chamber of roll body, it is characterized in that: the internal diameter at roll body central cavity both ends constitutes the cavity that holds calandria greater than the middle part.Roll body is integrative-structure, and is simple in structure, compact, uses, transports all very convenient.

Described calandria is electric heater or the electromagnetic heater that is fixed in the cavity.By electrical heating, avoid the loss of heat in transmission course.

Inside, described heat-conducting medium chamber is for negative pressure and be filled with the superconduction heat-conducting medium.It is faster to vacuumize the back heat-transfer rate, and the thermal efficiency is higher.

Described heat-conducting medium chamber has a plurality of, and is uniform along roll body barrel circumferential interval.Guarantee homogeneous heating.

Described heat-conducting medium chamber quantity is preferably 8.

Described heat-conducting medium chamber cross section is preferably circle.Circular hole is easy to process, is heated evenly.

Compared with prior art, the beneficial effect that has of the utility model superconducting heat collection follower is:

1, simple in structure, compact, long service life: roll body is integrative-structure, uses and transports very conveniently, and reliable operation can be used for a long time;

2, thermal efficiency height: also to central cavity input heat, continuous outside quantity of heat given up again after the inner chamber heat is saturated has effectively improved the thermal efficiency, saves the energy in the time of the outside quantity of heat given up in heat-conducting medium chamber;

3, environmental protection, safety: this superconducting heat collection follower is by self electrical heating, and is pollution-free; Do not have unsafe factors such as leakage in the use;

4, heating is effective: fill the superconduction heat-conducting medium in the heat-conducting medium chamber and vacuumize sealing, programming rate is very fast, heats effective;

5, applied range: this superconducting heat collection follower temperature range is broad, can be applicable to a plurality of industries such as papermaking, weaving, printing and dyeing and heating, drying.

The specific embodiment

Fig. 1～4th, the most preferred embodiment of the utility model superconducting heat collection follower is described further below in conjunction with 1～4 pair of the utility model of accompanying drawing.

With reference to accompanying drawing 1～4: the superconducting heat collection follower comprises roll body 1, heat-conducting medium chamber 2, cavity 3, calandria 4, rotating shaft 5, flange 6, axis hole 7, bearing 8.

Columnar roll body 1 is the integrative-structure of casting, the chromium plating after polishing of roll body 1 outer wall, eight heat-conducting medium chambeies 2 of axially running through barrel are arranged on roll body 1 barrel, and heat-conducting medium chamber 2 cross sections are circular hole, and all heat-conducting medium chambeies 2 are uniform along roll body 1 barrel circumferential interval.Vacuumize last 2 two ends, confined bed thermal medium chamber after filling the superconduction heat-conducting medium in the heat-conducting medium chamber 2.The internal diameter at roll body 1 central cavity both ends constitutes the cavity 3 that holds calandria 4 greater than the middle part at roll body 1 central cavity two ends, calandria 4 is for being fixed on electric heater or the electromagnetic heater in the cavity 3.

Roll body 1 both ends of the surface are fixedly connected flange 6 respectively, and flange 6 is sealed at both ends with roll body 1, and flange 6 lateral surfaces are provided with coaxial axis hole 7, and two rotating shafts 5 coaxial with roll body 1 head into respectively in the axis hole 7, are provided with bearing 8 between rotating shaft 5 and the axis hole 7.

Operation principle and the course of work are as follows: after calandria 4 energisings, owing to be filled with the superconduction heat-conducting medium in the heat-conducting medium chamber 2, heat up rapidly in heat-conducting medium chamber 2, temperature can reach 480 degree in 45 minutes, two rotating shafts 5 are moving linearly in the horizontal direction, roll body 1 is pressed in back rolling on the heating object, heat-conducting medium chamber 2 is near the outer quantity of heat given up of a side direction of roll body 1 outer wall, the heating heating object, heat-conducting medium chamber 2 is near input heat in the side direction of roll body 1 central cavity, outside quantity of heat given up continuously again after the heat of roll body 1 central cavity is saturated has effectively improved the thermal efficiency, saves cost.

Wherein the quantity in heat-conducting medium chamber 2 is freely selected according to roll body 1 size and temperature requirement, and roll body 1 central cavity can only at one end arrange cavity 3, only at an end of roll body 1 central cavity a calandria 4 is installed.

The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment does, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
