Description

Heating type heat preservation clothes for boiling bed

Technical Field

The utility model relates to a production device of crosslinked polyethylene for power cable, in particular to a heating type heat preservation clothes applied to a fluidized bed for producing polyethylene materials.

Background

At present, in the production process of polyethylene material for power cables in one-step method, a boiling bed is used for heating base material particles (specifically, hot air provided by a blower 7 and a heater 6 is used for heating). The heating effect of the fluidized bed depends on the heating time, the heating temperature and the ambient temperature, and in the actual production process, the heating effect of the fluidized bed is greatly influenced by the ambient temperature, the ambient temperature is too low, and the heating effect is poor. The heating time directly affects the productivity and the production cost. The heating temperature is low, the heating effect is poor, the heating temperature is too high, particle sticking agglomeration is easily caused, and the quality of finished products is influenced. When in production, if the heating effect of the boiling bed is not good and the temperature of the particle material is too low, the additive can be poorly and unevenly absorbed, and the quality of the finished product is seriously affected.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming not enough among the above-mentioned background art, providing an add hot type heat preservation clothing for ebullated bed, the device should be able to effectively reduce the influence of external environment temperature to ebullated bed heating effect to have simple structure, characteristics with low costs.

The technical scheme of the utility model is that: a heating thermal garment for a boiling bed; the method is characterized in that: the heating type heat preservation clothes comprise at least one group of electric heating belts wound outside the barrel wall of the boiling bed, a sponge heat preservation layer covering the boiling bed and the electric heating belts together, and a controller for connecting a power supply with the electric heating belts through a lead.

The electric heating belt is bonded outside the wall of the boiling bed barrel through a plurality of aluminum foil adhesive tape blocks.

the electric heating belt is a constant temperature heating belt, and the maximum temperature is set to be 65 ℃.

The utility model has the advantages that:

The utility model discloses an increase constant temperature heating tape and sponge heat preservation in the boiling bed outside, before the boiling bed work, open the constant temperature heating tape, preheat boiling bed bucket wall and inside temperature in advance. When the boiling bed normally works, the constant temperature heating belt is always kept at 60 ℃, the external sponge heat-insulating layer reduces the heat exchange between the boiling bed and the external environment, the external working temperature of the boiling bed is kept at 60 ℃, and the heating effect of the boiling bed is effectively ensured. The heating belt is a constant temperature heating belt, the maximum working temperature is 65 ℃, and local overheating of the barrel wall of the boiling bed and particle sticking caused by the local overheating can not be caused during working.

Drawings

Fig. 1 is a schematic view of the structure of the present invention.

Detailed Description

The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following embodiments.

The heating type heat preservation clothes for the boiling bed as shown in figure 1 comprises at least one group of electric heating belts 2 (shown in the figure: the electric heating belts are spirally wound outside the barrel wall of the boiling bed 1) wound outside the barrel wall of the boiling bed, a controller 4 is also arranged, and the electric heating belts, the controller and a power supply are sequentially connected through leads; one or two groups of electric heating belts can be started through the controller according to the actual production requirement. The electric heating belt is preferably a constant temperature heating belt.

A sponge insulating layer 5 is also arranged outside the barrel wall of the fluidized bed; the sponge heat-insulating layer coats the barrel wall of the fluidized bed and the electric heating belt together (the observation window part of the fluidized bed cannot be coated; the production condition of particles needs to be observed and monitored during production), and further the heat-insulating purpose is achieved.

Further, the heating tape is fixed on the wall of the boiling bed barrel through an aluminum foil adhesive tape 3.

All the component materials in the utility model can be purchased and obtained.

The utility model discloses a theory of operation is:

1. After the heating type heat preservation clothes are installed on the boiling bed, the constant temperature heating belt can be started before production, and the barrel wall and the internal temperature of the boiling bed can be preheated, so that the external temperature is always constant below 65 ℃ when the boiling bed works normally;

2. The metal barrel wall of the original boiling bed is directly contacted with the external air, so that more heat exchange is carried out with the external air during working, the heating effect of the boiling bed is reduced, and after the sponge heat-insulating coat is installed, the heat exchange between the boiling bed and the external air is reduced, and the heating effect of the boiling bed is increased;

3. The opening number of the constant temperature heating belts can be controlled by adjusting the constant temperature heating belt controller, and the heating effect of the boiling bed with different temperatures and yields is met.

Claims
