Abstract
The invention relates to a spiral plate heat exchanger made of two steel plates through coiling and a production method thereof. The spiral plate heat exchanger is designed to mainly solve the problem of the existing spiral plate heat exchanger that the welding amount is large and the leakage points are in a large quantity. The upper edge and the lower edge of the two spiral plates for forming a spiral body are respectively bended outward and lapped on the end face of the adjacent spiral plate and then welded and sealed, and a strengthening seal angle is additionally arranged at the angle part between the spiral plate and a division plate. The production method comprises the following steps: coiling two pieces of steel plates into a spiral body, forming two uniform spiral channels, arranging a division plate in the middle of the spiral body, respectively welding and sealing the two edges of the division plate with the inner ends of the two spiral plates, bending the upper edge and the lower edge of the spiral plate of each channel of the spiral body outward and lapping the edges to the end surface of the adjacent spiral plate to be welded and sealed, and arranging a bracket under the spiral body. The spiral plate heat exchanger and the production method have the advantages that the welding amount is small, the leakage points are in a small quantity, and the production cost is low.
Description
Technical field:
The present invention relates to the heat-exchanger rig that industries such as a kind of metallurgy, chemical industry, oil, medicine, food are used, particularly roll spiral plate type heat-exchanger rig and the production method thereof that forms by two steel plates.
Background technology:
Existing spiral heat exchanger conveyor screw is rolled by two steel plates and forms, form two uniform helical ducts, the centre with demarcation strip with two passages separately, the upper and lower opening of helical duct blocks sealing with round steel or steel bar, shortcoming is: the upper and lower opening of each passage respectively has the twice weld seam, and welding capacity is big, and leak source is many, labour intensity is big, the cost height; Demarcation strip and spiral plate weld be washing away and corroding and leak because of medium easily.
Summary of the invention:
It is little that technical problem to be solved by this invention provides a kind of welding capacity, and tolerance dielectric corrosion and scouring force are strong, antileakaging spiral heat exchanger and production method thereof.
Above-mentioned purpose is achieved in that and same as the prior art is, it comprises conveyor screw, conveyor screw is made up of two spiral plates (steel plate), form two uniform helical ducts, be refrigerant passage and heating agent passage, demarcation strip is arranged in the middle of the conveyor screw, the both sides of demarcation strip respectively with the inner end welded seal of two spiral plates, refrigerant passage and heating agent passage are separated, refrigerant passage has refrigerant medium inlet and refrigerant media outlet, the heating agent passage has thermal medium inlet and thermal medium outlet, there is support conveyor screw below, unlike the prior art be, form spirochetal two spiral plates (steel plate) on, lower limb all outwards bends from the lining, bending part is that spiral plate is taken the angle, and spiral plate is taken the angle and snapped on the adjacent spiral plate end face and welded seal.
In order to make demarcation strip and spiral plate weld more solid and reliable, can set up the enhanced leaktightness angle at spiral plate and demarcation strip angle, the enhanced leaktightness angle respectively with spiral plate and demarcation strip welded seal.
Production method of the present invention is: make conveyor screw with two roll of steel plate, make it form two uniform helical ducts, be refrigerant passage and heating agent passage, in the middle of conveyor screw, establish demarcation strip, with the both sides of demarcation strip respectively with the inner end welded seal of two spiral plates, refrigerant passage and heating agent passage are separated, according to the width of passage with on the spiral plate (steel plate) of each passage of conveyor screw, lower limb is outwards pulled the folding certain height from the lining, snap on the adjacent spiral plate end face and welded seal, on refrigerant passage, establish refrigerant medium inlet and refrigerant media outlet, establish thermal medium inlet and thermal medium outlet on the heating agent passage, support is established in the conveyor screw below.
Can also set up the enhanced leaktightness angle at spiral plate and demarcation strip angle, with the enhanced leaktightness angle respectively with spiral plate and demarcation strip welded seal.
Advantage of the present invention is: the upper and lower limit of each passage has only weld seam respectively one, and welding capacity is little, and leak source is few, and production cost is low; Owing to set up the enhanced leaktightness angle at spiral plate and demarcation strip angle, it is more solid and reliable that spiral plate is connected with demarcation strip, and tolerance dielectric corrosion and scouring force are strong, so be difficult for leaking long service life.
