Abstract
A kind of MVR vapour compression machine titanium plate welds volute structure, be by intake air impeller lid, shell, diffuser, rear flange board group at;It is characterized in that intake air impeller lid is installed on housing forward end, diffuser is installed on rear flange plate, is installed on housing rear end by the overall structure that diffuser and rear flange plate are constituted, the whole titanium plate constituted welds volute structure.The utility model is that a kind of fabrication cycle is short, at low cost, service-strong MVR vapour compression machine titanium plate welding volute structure.
Description
Technical field
The utility model relates to MVR evaporative crystallization industries, are used suitable for evaporation Special Corrosion material with compressor.
Background technique
At home since when some special material evaporations, a large amount of corrosive gas are contained in secondary steam in MVR system
Medium, it is very serious to the corrosion of pipeline, impeller and spiral case corrosivity especially to MVR vapour compression machine it is very strong (due to
Flow velocity is very high in MVR vapour compression machine spiral case, very serious to the cavitation erosion of spiral case), to solve this problem, spiral case material need to adopt
With titanium material.Since not only fabrication cycle is long for the casting of titanium spiral case, and it is difficult, and cost is very high.
Utility model content
The utility model can effectively solve above-mentioned technological deficiency, provide that a kind of fabrication cycle is short, at low cost, service-strong
MVR vapour compression machine titanium plate welds volute structure.
To achieve the above object, the technical solution adopted in the utility model is a kind of MVR vapour compression machine titanium plate welding snail
Shell structure, be by intake air impeller lid, shell, diffuser, rear flange board group at;It is characterized in that intake air impeller lid is installed on shell
Front end, diffuser are installed on rear flange plate, are installed on housing rear end by the overall structure that diffuser and rear flange plate are constituted,
The whole titanium plate of composition welds volute structure.
Due to the adoption of the above technical scheme, compared with casting titanium spiral case, titanium welds the delivery cycle of spiral case significantly
Shorten, welds split type structure by using titanium, ensure that the production of spiral case all parts can be finished individually, very well
Guarantee spiral casing flow passage finish, to improve compressor service performance and efficiency have large increase.

Specific embodiment
The utility model will be further described with reference to the accompanying drawing, not to the limitation of its protection scope.
A kind of MVR vapour compression machine titanium plate welding volute structure, is by intake air impeller lid (1), shell (2), diffuser
(3), rear flange plate (4) forms;It is characterized in that intake air impeller lid (1) is installed on shell (2) front end, diffuser (3) is installed on
On rear flange plate (4), shell (2) rear end is installed on by the overall structure that diffuser (3) and rear flange plate (4) are constituted, is constituted
Whole titanium plate weld volute structure.It is greatly shortened using the delivery cycle of its titanium of this scheme welding spiral case, by using titanium
Material welds split type structure, and titanium plate welding volute structure is divided into intake air impeller lid (1), shell (2), diffuser (3), rear flange
(4) four parts of plate form;Its intake air impeller lid (1) is provided with air inlet guide shell (1a), while diffuser (3) is provided with 11
Diffuser vane (3a), and circumference uniform distribution can individually finish air inlet guide shell (1a) and diffuser (3), be guaranteed
The surface light of 11 diffuser vanes (3a) of the perfect cooperation and diffuser (3) in intake air impeller lid (1) and unshrouded impeller gap
Cleanliness has large increase to the service performance and efficiency that improve compressor.Its shell (2) side of being provided with is rounded (2a) structure guarantor
The connection of spiral case and live round pipe is demonstrate,proved;Shell (2) is provided with U-shaped gusset (2b) structure and guarantees that titanium welds snail well
The rigidity of shell.
Therefore, the utility model is that a kind of fabrication cycle is short, the weldering of at low cost, service-strong MVR vapour compression machine titanium plate
Connect volute structure.
