Abstract
The utility model relates to a special plate heat exchanger's of liquid crystal state medium slab, through the special slab of the semi-solid state medium of design (liquid crystal state), ripple on a slab has two kinds of high formations at least, two slabs stack the back, because there is the difference in height with the ripple of a slab, and there is certain trend, ripple on two slabs is not criss-cross each other, the seam has formed the whirl passageway in the middle of the ripple of same trend, after liquid crystal state medium gets into plate heat exchanger's whirl passageway, can be along with the difference in height and the trend of whirl passageway, it is rotatory flowing, and then the mobility of liquid crystal state medium has been increased, make the medium difficult crystallization. In addition, the sealing grooves between the plates adopt concave embedded structures, the sealing grooves are W-shaped, and the rubber rings can be limited left and right after being placed in the sealing grooves, so that the pressure-bearing buffering effect is effectively achieved.
Description
Technical Field
The utility model relates to a special plate heat exchanger's of liquid crystalline state medium slab belongs to heat exchanger technical field.
Background
The plate heat exchanger is widely applied to various production industries, is excellent equipment for heating, cooling, heat recovery and quick sterilization, and is a high-efficiency heat exchanger formed by stacking a series of metal plates with certain corrugated shapes. The main constituent parts of the plate heat exchanger are plates with various structures, thin rectangular channels are formed among the plates, heat exchange is carried out through the plates, and the corrugated intersection between the plates not only forms the channels, but also has the functions of pressure bearing and fixing.
At present, the plate heat exchanger has not been paid extensive attention in the application field of the medicine and food industry, and the main reason is that the heat exchanger selected in the industry is required to complete the heating and cooling effects of a semi-solid medium (liquid crystal state). The flow channels between the normal plates of the plate heat exchanger are small and are staggered in stages, semi-solid medium (liquid crystal state) is poor in liquidity and easy to crystallize, and once the medium crystallizes to block the flow channels between the plates, the plate heat exchanger can be seriously failed or even scrapped.
Therefore, at present, domestic similar semi-solid medium (syrup, milk jelly and the like) manufacturers select heat exchangers in other forms and then complete the process by matching auxiliary facilities, and the heat exchange mode has the disadvantages of high energy consumption, low efficiency and secondary (filling and transportation) pollution risk.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned not enough, provide an increase liquid crystal state medium's mobility, avoid the crystallization to can play the special plate heat exchanger's of liquid crystal state medium slab of pressure-bearing cushioning effect effectively.
The purpose of the utility model is realized like this:
the utility model provides a special plate heat exchanger's of liquid crystal state medium slab, seted up the through-hole on four angles of slab, be heat medium inflow through-hole, heat medium outflow through-hole, cold medium inflow through-hole, cold medium outflow through-hole respectively, the openly centre from the top down of slab is equipped with many ripples, and every ripple is the sectional type design, and the ripple on a slab has two kinds of highly formations at least, and two slabs stack the back, and the ripple on two slabs is intercrossing, and the seam has formed the whirl passageway in the middle of the ripple in same trend, be equipped with the seal groove on the slab, the rubber ring is put into in the seal groove.
Preferably, the corrugations are in the shape of chevrons.
Preferably, the upper end and the lower end of the surface of the plate are provided with guide rod holes.
Preferably, the plate sheet is made of stainless steel materials.
Preferably, the swirl passage forms a closed passage and has a height difference.
Preferably, the sealing groove is W-shaped.
Compared with the prior art, the beneficial effects of the utility model are that:
the plate of the plate heat exchanger special for the liquid crystal state medium is designed by the special plate of the semi-solid state medium (liquid crystal state), the corrugation on one plate is at least formed by two heights, after the two plates are stacked, because the corrugation of the same plate has a height difference and a certain trend, the corrugations on the two plates are not crossed, the middle gap of the corrugation in the same trend forms a rotational flow channel, and after the liquid crystal state medium enters the rotational flow channel of the plate heat exchanger, the liquid crystal state medium can flow in a rotating mode along with the height difference and the trend of the rotational flow channel, so that the liquidity of the liquid crystal state medium is increased, and the medium is not easy to crystallize. In addition, the sealing grooves between the plates adopt concave embedded structures, the sealing grooves are W-shaped, and the rubber rings can be limited left and right after being placed in the sealing grooves, so that the pressure-bearing buffering effect is effectively achieved.

Fig. 2 is a schematic view of the middle panel of fig. 1 after stacking.
Fig. 3 is a schematic diagram of the sealing groove of the plate heat exchanger special for liquid crystal medium of the present invention.
Wherein: the plate comprises a plate 1, a heat medium inflow through hole 2, a heat medium outflow through hole 3, a cold medium inflow through hole 4, a cold medium outflow through hole 5, a guide rod hole 6, corrugations 7, a rotational flow channel 8, a sealing groove 9 and a rubber ring 10.
Detailed Description
Referring to fig. 1 to 3, the utility model relates to a special plate heat exchanger's of liquid crystalline state medium slab, slab 1 is made for stainless steel material, has guaranteed that the heat exchanger of making can be durable for a long time.
Through holes are formed in four corners of the plate 1, the through holes are respectively a heat medium inflow through hole 2, a heat medium outflow through hole 3, a cold medium inflow through hole 4 and a cold medium outflow through hole 5, and the positions of the four through holes can be changed according to installation requirements.
