Abstract
The utility model discloses one and scrape sheet heat exchanger, comprise main shaft, material barrel and shell, described main shaft is located in material barrel, described main shaft left-hand end is arranged on the left end cover of material barrel rotationally by bearing, the right-hand end of described main shaft is connected with the driving shaft of the drive motors through right end cover, described main shaft is provided with material scraper plate, described main shaft inside is with hollow pipeline, the side of described main shaft with the spray-hole of hollow pipeline conducting, the left-hand end of described main shaft with the interface of hollow pipeline conducting.This scrapes sheet heat exchanger can carry out internal washing very easily, also can reach flash heat transfer and the object of avoiding producing the bad phenomenon such as coking film or feed liquid crystallization on heat-transfer area.
Description
Technical field
The utility model relates to one and scrapes sheet heat exchanger.
Background technology
Existing plate type heat exchanger and pipe heat exchanger, because feed liquid is that nature passes through heat exchanger, therefore, flow slow, and heat transfer efficiency is low, and heat exchange is slow, at moment high temperature sterilization or during instantaneous cooling processes, the heat-transfer area of above-mentioned heat exchanger easily generates coking film or feed liquid crystallization.
Summary of the invention
In view of the deficiency of background technology, technical problem to be solved in the utility model is to provide fast, the difficult generation coking film of a kind of heat transfer rate or feed liquid crystallization, and is convenient to carry out the sheet heat exchanger of scraping of internal washing.
For this reason, the one that the utility model provides is scraped sheet heat exchanger, comprise main shaft, material barrel, medium cylinder and with the shell of heat-insulation layer, it is characterized in that: described main shaft is located in material barrel, described main shaft left-hand end is arranged on the left end cover of material barrel rotationally by bearing, the right-hand end of described main shaft is connected with the driving shaft of the drive motors through right end cover, described main shaft is provided with material scraper plate, described main shaft inside is with hollow pipeline, the side of described main shaft with the spray-hole of hollow pipeline conducting, the left-hand end of described main shaft with the interface of hollow pipeline conducting.
The scraper plate heat exchanger that the utility model provides has that heat exchange efficiency is high, heat loss is little, advantages of compact and light structure, installation easy to clean, be widely used, the feature such as long service life.Under uniform pressure damaed cordition, doubly, area is pipe heat exchanger to the high 3-5 of its ratio of heat transfer coefficient pipe heat exchanger 1/3rd, and heat recovery rate can be up to more than 90%.But also have the advantages that to be difficult for generating coking film or feed liquid crystallization.The more important thing is after the structure adopting with vacant duct and spray-hole, be more convenient to carry out internal washing, avoid residual material rotten.
Brief description of the drawings
The structure cross-sectional schematic of scraping sheet heat exchanger that Fig. 1 provides for the utility model.
Fig. 2 is that the structure of the main shaft in Fig. 1 is analysed and observe enlarged diagram.
Detailed description of the invention
As Fig. 1, shown in Fig. 2, what the utility model provided scrapes sheet heat exchanger, comprise main shaft 1, material barrel 2, medium cylinder 3 and with the shell of heat-insulation layer 4, described main shaft 1 is located in material barrel 2, described main shaft 1 left-hand end is arranged on the left end cover 5 of material barrel rotationally by bearing, the right-hand end of described main shaft 1 is connected with the driving shaft 6 of the drive motors through right end cover, described main shaft 1 is provided with material scraper plate 7, described main shaft 1 inside is with hollow pipeline 8, the side of described main shaft 1 with the spray-hole 9 of hollow pipeline 8 conductings, the left-hand end of described main shaft 1 with the interface 10 of hollow pipeline conducting.In the present embodiment, the interior band of described main shaft 1 is useful on the sealing cylinder 11 of sealing spray-hole, sealing cylinder 11 sides are with hollow-out parts 11a and closure 11b, on described left end cover 5 with the turning collar 12 that is exposed to left hand external, turning collar 12 inner sides are connected with sealing cylinder 11, sealing cylinder 11 linings are in hollow pipeline 8, user can seal cylinder 11b by rotation and control opening and sealing spray-hole 9, in the time that the closure 11b of sealing cylinder 11 covers spray-hole 9, heat exchanger can be started working, in the time that cleaning heat exchanger, needs can rotate sealing cylinder 11, impel hollow-out parts 11a to aim at spray-hole 9, make High-Pressure Water be injected in device interior by spray-hole 9, reach the object of cleaning.
In the present embodiment, scraped surface heat exchanger, mainly to be formed by motor, main shaft 1 and material barrel 2, on the inwall of material barrel, there is one or more groove, a kind of new type high efficient heat exchanger that main shaft 1 is hollow tubular structure, carrying out exchange heat by half sheet, is to realize the ideal equipment that liquid-liquid, liquid-vapour carry out heat exchange.This scraper plate heat exchanger has that heat exchange efficiency is high, heat loss is little, advantages of compact and light structure, installation easy to clean, be widely used, the feature such as long service life.Under uniform pressure damaed cordition, doubly, area is pipe heat exchanger to the high 3-5 of its ratio of heat transfer coefficient pipe heat exchanger 1/3rd, and heat recovery rate can be up to more than 90%.
In the time of equipment operation, material is from material import and export turnover mobile between groove, heat medium is imported and exported turnover and flows main shaft from medium, under different axial flow velocities and mixing speed effect, be various flow velocitys, feed liquid when the material barrel, is divided into axial flow and rotating flow in the axle in material barrel, in the time that axial flow and rotating flow are Laminar Flow, its flow pattern travels forward generally in the shape of a spiral, feed liquid axial flow velocity to be distributed in different radii different.Matter heats material by heat-transfer area, when main shaft rotates under driven by motor, groove stirs feed liquid between main shaft and material barrel, and scrape on the heat-transfer area of main shaft, and then cleaning heat transfer face, thereby reach flash heat transfer and the object of avoiding producing the bad phenomenon such as coking film or feed liquid crystallization on heat-transfer area.
