Abstract

The utility model relates to a detatchable spiral chamber heat exchanger, relating to a device for reclaiming the heat energy produced after cooled the hot fluid for the process of the manufacture of the edible oil, etc. The integral structure of the utility model comprises a heat exchanger body and a position select bracket. The heat exchanger body is provided with a detatchable sealing end cover. Two rolling iron plates are outfitted to form heat exchange spiral double cavities. Each kind of the spiral double cavities have one end which is a detatchable spiral sealing bottom. The spiral cavity is provided with an even depressor. The heat exchanger body can rotate on the position select bracket. The operating posture can be selected discretionarily. The heat exchanger can be disassembled to repair.

Description

Detatchable spiral chamber heat exchanger

This removable helical cavity heat exchanger relates in the edible wet goods processing, and heat of cooling fluid is also recycled a kind of device of its heat energy, and international Patent classificating number is F28D/14.

In refining raw food oil is produced, thick oil brought up under 240 ℃ of situations carry out, after making, the refined oil product still has so high temperature.Naturally scatter and disappear if let alone heat, reducing to storage at normal temperature will be a kind of great thermal waste with selling.In order to recycle this partly heat energy, be to use heat exchanger apparatus to carry out in the production.The heat exchanger technology that uses has two kinds substantially at present.A kind of non-disconnectable spiral-plate heat exchanger of domestic production, it can't be repaired, and goes wrong to change new product; Having a kind of abroad is removable heat exchanger, but its heat exchange cavity is the triangle cavity, and its manufacturing processing need have special equipment to realize.The operating attitude of these two kinds of heat exchangers (vertical, horizontal, inclination) all can not freely be selected, and orders and need give.

Goal of the invention of the present utility model, being to provide a kind of can not leak according to not mixing between operating position dismounting maintenance, helical cavity, has even compression functions.The optional design of heat exchanger of operating attitude.

Major technique feature of the present utility model is: the general structure of heat exchanger comprises heat exchange body 1 and 2 two parts of bit selecting support.By bit selecting semiaxis 3 heat exchange body 1 is installed on the bit selecting support 2.This heat exchanger can carry out thermal energy exchange for the hot fluid (heat exchange medium) of two kinds of different temperatures.Heat exchange body 1 two ends are equipped with dismountable end cover 4, can make heat exchanger do regular internal check maintenance.The inside heat exchange structure of heat exchange body 1 is to roll two not connected heat exchange cavities that the spiral plate suit forms by two, it is inside and outside for comparatively speaking to be divided into inside spin chamber 12 and external spiral chamber 13(), the internal and external screw chamber is arranged on the flange shell 10 of heat exchange body and is with between the core tube 6 of cinclides 11, and the even depressor 8 of counterpressure is housed in the internal and external screw chamber.Heat exchange body 1 can select to take vertically-arranged, horizontally-arranged or inclination operating attitude by bit selecting semiaxis 3 rotation of working on the bit selecting support.It is the non-disconnectable helix closed end that respectively there is the end of an end in the internal and external screw chamber, and the sealing direction is opposite, and the other end is an opening.There is the non-removable following helix closed end 16 in inside spin chamber 12, and there is non-removable going up at the helix closed end 15 in external spiral chamber 13.In the end cover 4 of heat exchange body 1 heat-insulation layer 14 is housed, is provided with hot fluid in the central authorities of covering and advances (going out) mouth 5.On the symmetry direction of the perisporium of heat exchange body 1, also be provided with hot fluid and enter (going out) mouthfuls 5, hot fluid advances the diverse location of the design of (going out) mouth 5, can guarantee the difference turnover flow direction of two kinds of hot fluids and carry out countercurrent flow, a kind of hot-fluid side mouth entry port is flowed out, and another kind of hot fluid can flow out at port approaching side mouth, favourable raising heat exchange efficiency.

Advantage of the present utility model:

This detachable helical cavity heat exchanger can be dismantled maintenance in producing use, can clear up inner incrustation, obstruction etc., can continue after clearing up or repairing to use;

Owing to be provided with even depressor, the distortion that can avoid pressure reduction to cause has prevented to produce heat exchange efficiency decline and the obstruction of helical cavity channel deformation in the use in its each chamber.

Its operating attitude can be selected to determine, and needn't be scheduled to producer when equipment purchasing in produce use as required.

Embodiment is described below in conjunction with the accompanying drawings:

This removable helical cavity heat exchanger branch is made heat exchange body 1 and 2 liang of parts of bit selecting support.

Heat exchange body 1: outside flange shell 10 is the flanged (FLGD) thick cylinders in two ends, central authorities' vertically-arranged has the core tube 6 of band cross frame plate 7, core tube 6 perisporiums have and adhere to the through hole 11 that enters the internal and external screw chamber separately, one plate of cross frame plate 7 is an imperforate plate, make preceding half chamber 17 and later half chamber 18 isolated mutually, another plate is that abacus only plays the support effect, does not have insulating effect (hole of not drawing among the figure).Inside spin chamber 12, external spiral chamber 13 are two and roll the cavity that adheres to two kinds of flow of heated fluid warps separately that forms behind the iron plate suit, the inner and the 6 sidewall seam of core tube, outer end and the 10 inwall seam of flange shell, there were the following helix closed end 16 and the last helix closed end 15 in inside spin chamber 12 and external spiral chamber 13 seam respectively; All be added with the even depressor of all putting 8 in the internal and external screw chamber each week; The openend in internal and external screw chamber is installed rear enclosed by end cover 4 and sealing gasket 9.Symmetry has hot fluid and enters (going out) mouthfuls 5 on the sidewall of heat exchange body 1, is symmetrical arranged bit selecting semiaxis 3 on perpendicular direction.

End cover 4, two end cover structures are identical up and down, sealing function is identical, its central authorities have with heat exchange body 1 on identical hot fluid enter (going out) mouthfuls 5, the inside of lid is added with heat-insulation layer 14(and adopts perlite).Sealed end is stamped bolt and is connected with flange end with the heat exchange body, and sealing gasket 9 wherein is housed.

Bit selecting support 2 is the herringbone brandreth, and there is axle bed and the location that cooperates with bit selecting semiaxis 3 upper end.The heat exchange body can be done the circumference adjustment thereon and rotate, and can need to determine suitable operating attitude by producing.
