Description
Technical field
The utility model relates to mechanically-sealing apparatus technical field, particularly a kind of process for production of polyether polyols cooling mechanical seal device.
Background technology
Mechanical seal is that a kind of use solves the device sealing between turning axle and body.By at least one pair of end face perpendicular to rotation, under hydrodynamicpressure and the effect of shim mechanism elastic force (or magnetic force) and the cooperation of auxiliary seal, kept laminating relatively sliding and form the device that prevents escape of liquid, be usually used in the rotary type fluid machines such as pump, compressor, reaction stirring tank, also for sealings such as wheel casing, valve, swivel joint, marine rear shafts.
With bimetal, carrying out in the process for production of polyether polyols of catalytic production, prior art is to utilize water cycle to carry out cooling mechanical seal, because recirculated water in production process has dirt unavoidably, so just cause the breakage of machine envelope, it is undesired to cause producing, drop into a large amount of maintenance costs, reduced production efficiency, affected the quality of production.
Summary of the invention
The purpose of this utility model is for the defect of prior art and deficiency, and process for production of polyether polyols cooling mechanical seal device a kind of simple in structure, reasonable in design, long service life is provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of process for production of polyether polyols cooling mechanical seal device described in the utility model, comprise machine envelope, water circulating pump, material inlet valve, coolant valve, loop valve and cooling tank, water circulating pump is arranged between cooling tank and machine envelope, by pipeline, connect, material inlet valve is arranged on the pipeline of ligation still import, coolant valve is arranged on the pipeline that connects cooling tank import, and loop valve is arranged on the pipeline of the outlet of junctor envelope and cooling tank entrance.
Further, in described cooling tank, annular coil pipe is installed.
Adopt after said structure, the utility model beneficial effect is: a kind of process for production of polyether polyols cooling mechanical seal device described in the utility model, comprise machine envelope, water circulating pump, material inlet valve, coolant valve, loop valve and cooling tank, water circulating pump is arranged between cooling tank and machine envelope, by pipeline, connect, material inlet valve is arranged on the pipeline of ligation still import, coolant valve is arranged on the pipeline that connects cooling tank import, and loop valve is arranged on the pipeline of the outlet of junctor envelope and cooling tank entrance.The utility model, at circulating cooling system, has increased a cooling tank, and the inside is provided with coil pipe, and it is cooling to utilize raw material to carry out machine envelope, has greatly improved machine envelope system, has avoided water to pollute the destruction to machine envelope.The utlity model has simple in structurely, arrange rationally, long service life etc. advantage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Description of reference numerals:

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of process for production of polyether polyols cooling mechanical seal device described in the utility model, comprise machine envelope 2, water circulating pump 8, material inlet valve 4, coolant valve 5, loop valve 6 and cooling tank 7, water circulating pump 8 is arranged between cooling tank 7 and machine envelope 2, by pipeline, connect, material inlet valve 4 is arranged on the pipeline of ligation still 1 import, coolant valve 5 is arranged on the pipeline that connects cooling tank import, and loop valve 6 is arranged on the pipeline of 2 outlets of junctor envelope and cooling tank 7 entrances.
Further, in described cooling tank 7, annular coil pipe 3 is installed.
When using the utility model, first open coolant valve 5, close loop valve 6 and material inlet valve 4 simultaneously, raw material enters into cooling recirculation system, then closes coolant valve 5, opens loop valve 6 simultaneously, when needs reactor 1 is started working, open material inlet valve 4, ON cycle water pump 8.
The utility model circulating cooling system, has increased a cooling tank 7, and the inside is provided with coil pipe 3, and it is cooling to utilize raw material to carry out machine envelope, has greatly improved machine envelope system, has avoided water to pollute the destruction to machine envelope.The utlity model has simple in structurely, arrange rationally, long service life etc. advantage.
The above is only better embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
