Be arranged on delivery side of pump by cooling the sealing of this chemical pump machinery with clear liquid separator, connection mouth on the middle shell sidewall of clear liquid separator is communicated with mechanical seal cooling liquid inlet by cooling liquid liquid inlet pipe, and mechanical seal cooling liquid liquid port is communicated with chemical pump import by cooling liquid liquid-discharging tube.Part is transferred liquid after the filter element filtering in clear liquid separator, and gained cleaner liquid enters mechanical seal cooling chamber through cooling liquid liquid inlet pipe and mechanical seal carried out cooling, then enters chemical pump material feeding mouth through cooling liquid liquid-discharging tube.
Accompanying drawing explanation
Fig. 1 is the cooling structural drawing with clear liquid separator of chemical pump machinery sealing;
Fig. 2 is the cooling application schematic diagram with clear liquid separator of chemical pump machinery sealing.
Embodiment
As shown in Figure 1, the sealing of this chemical pump machinery is cooling comprises upper shell 11, middle shell 12, lower shell body 17, filter core 13, upper sealing gasket 14, lower seal pad 16 and bolt 15 with clear liquid separator.11 one-tenth tubuloses of upper shell, there is an adpting flange 111 upper end, and there is an outwardly annulus 112 lower end.12 one-tenth tubuloses of middle shell, upper end has one to projecting inward annulus 121, has a connection mouth 122 on sidewall.17 one-tenth tubuloses of lower shell body, there is an adpting flange 171 lower end, and there is an outwardly annulus 172 upper end.13 one-tenth tubuloses of filter core.The internal diameter of upper shell, lower shell body and filter core is identical, and the internal diameter of middle shell is greater than the external diameter of filter core, and the external diameter of middle shell equals the external diameter of the annulus 112 of upper shell lower end, also equates with the external diameter of the annulus 172 of lower shell body upper end.The lower end of middle shell 12 is connected with annulus 172 sealings of lower shell body upper end.Filter core 13 is inserted in middle shell, lower seal pad 16 is between the lower end of filter core and the annulus 172 of lower shell body upper end, the inwall of the annulus 121 of the outer wall of the upper end of filter core and middle shell upper end is affixed, upper sealing gasket 14 is between the annulus 112 of upper shell lower end and the annulus 121 of middle shell upper end and filter core 13, the annulus 112 use bolts 15 of upper shell lower end fix with the annulus 121 of middle shell upper end, make upper shell 11, upper sealing gasket 14, middle shell 12, filter core 13, lower seal pad 16 and lower shell body 17 compress mutually, sealing, between middle shell and filter core, form a cavity.
As shown in Figure 2, by the cooling outlet that is arranged on chemical pump 5 with clear liquid separator 1 of this chemical pump machinery sealing, connection mouth on the middle shell sidewall of clear liquid separator is communicated with the cooling liquid inlet of mechanical seal 4 by cooling liquid liquid inlet pipe 2, and the cooling liquid liquid port of mechanical seal is communicated with the import of chemical pump by cooling liquid liquid-discharging tube 3.Utilize the pressure difference of chemical pump inlet/outlet, make part be transferred the filter element filtering of liquid in clear liquid separator, gained cleaner liquid enters the cooling chamber of mechanical seal 4 through cooling liquid liquid inlet pipe 2, mechanical seal is carried out cooling, then is inhaled into chemical pump material feeding mouth through cooling liquid liquid-discharging tube.
The sealing of this chemical pump machinery is cooling can be selected according to carried material with the filter core in clear liquid separator, can be by ultra-high molecular weight polyethylene (UHMW-PE) or the powder sintered microfiltration tube forming of polytetrafluoroethylene (PTFE), also can be filter mantle, can also be the metal powder sintered microfiltration tube forming.
The housing of clear liquid separator forms with Metal Material Welding, and its material can be carbon steel, stainless steel and other alloy material, should select according to the corrosivity of fed sheet of a media, and clear liquid separator and conveying material contact segment should select not produce the material of corrosion.The material of sealing gasket can adopt teflon etc. have certain flexible and make with the nonmetallic material that conveying material does not produce corrosion.Bolt is metallic material, can be the metallic material such as carbon steel, stainless steel and other alloy material, and it does not contact with conveying material, less demanding to corrosion resistance.
Be applied to chemical pump machinery with clear liquid separator and seal in cooling system cooling the sealing of this chemical pump machinery, can obtain good effect.For example, be used in multiple effect evaporation crystal system, because system is in vacuum state, the mechanical seal of raw material recycle pump adopts external water quench, often occurs that mechanical seal cooling water enters system, and is difficult to find, and affects manufacturing efficiency.Use after the utility model, thoroughly solved the problems referred to above.And for example, in solids-laden fluid is carried, originally mechanical seal adopts external water quench, but often occurs, because mechanical seal leakage produces material with cooling water flow out of, causing loss of material and environmental pollution.Use after the utility model, thoroughly solved the problems referred to above.
