Abstract
The utility model relates to a pipeline type aseptic centrifugal pump which is composed of a pump body, an impeller, a pump cover, a pump shaft and a mechanical seal component, wherein the end surface at the outer side of the pump cover is provided with an aseptic cylinder of which one end is fixedly connected with the end surface at the outer side of the pump cover; the pump shaft passes through and is arranged in the pump body and the aseptic cylinder; the impeller is fixedly arranged at one end of the pump shaft, which is arranged in the inner cavity of the pump body; the mechanical seal component is arranged between the pump shaft and the pump cover. Both sides of the aseptic cylinder are provided with visual mirror windows composed of visual mirrors and windows, and each visual mirror is connected with each window through a flange. A motor shaft penetrates through the aseptic cylinder, and is connected with the pump shaft. The mechanical seal component and the impeller are fixed on the pump shaft through nuts. When filled in the aseptic cylinder, the aseptic air isolates the pump shaft, the pump cover and the mechanical seal component from a passage which is infected by external bacteria, and thus, the centrifugal pump realize complete aseptic transportation. Thereby, the goal of aseptic transportation is achieved.
Description
Technical field:
The utility model relates to pump, particularly a kind of pipe type centrifugal pump, the aseptic centrifugal pump of especially a kind of pipe type.
Background technique:
In the prior art, aseptic demanding industry, as pharmaceutical industry, food beverage industry etc., the conveying of clean materials in its extensive sterile production process, all use pressurized air to carry, not contaminated in course of conveying in order to guarantee material, used air must be a disinfecting air, this just causes whole process cost high, and energy consumption is very big.The aseptic pump of existing what is called is a kind of no-leakage pump of health level on the market, only is applicable to the mass transport that aseptic process is preceding.Because the pump shaft and the mechanical seal of centrifugal pump of the prior art can not completely cut off bacterium fully, so centrifugal pump of the prior art can't realize carrying aseptic conveying.Therefore, some materials as zymotic fluid in the aseptic fermenting tub etc., still can only adopt the disinfecting air force feed, exist the operating cost height, the problem that energy consumption is big.
Summary of the invention:
Technical problem of the prior art to be solved in the utility model is: owing to can not completely cut off bacterium fully between the sealing of the pump shaft of centrifugal pump of the prior art and the pump housing, so centrifugal pump of the prior art can't realize carrying aseptic conveying.Therefore, some materials as zymotic fluid in the aseptic fermenting tub etc., still can only adopt the disinfecting air force feed, exist the operating cost height, the problem that energy consumption is big.
The utility model is that the technological scheme that solution above-mentioned technical problem of the prior art is adopted provides the aseptic centrifugal pump of a kind of pipe type, by the pump housing, impeller, pump cover, pump shaft and mechanical sealing assembly constitute, wherein, the inner side end of described pump cover is connected with the described pump housing, the outside end face of described pump cover is provided with an aseptic tank, one end of described aseptic tank is fixedlyed connected with the outside end face of described pump cover, described pump shaft pass described pump cover and be arranged on the described pump housing and described aseptic tank in, described impeller is fixedly installed on the end of pump shaft in pump housing inner chamber, and described mechanical sealing assembly is arranged between described pump shaft and the described pump cover.
Further, the other end of described aseptic tank is connected with the shell of a motor, and the output shaft of described motor is connected with described pump shaft.
Further, at least be provided with a visual mirror window in the sidewall of described aseptic tank, described visual mirror window is made of visor and window frame, described window frame is fixedlyed connected with described aseptic tank by flange arrangement, and described visor is arranged between the opening and described window frame of described aseptic tank sidewall.
Further, the other end of described aseptic tank is connected by bolt arrangement with the outside end face of described pump cover.
Further, described mechanical sealing assembly is fixed on the described pump shaft by nut.
Further, described impeller is fixed on the described pump shaft by nut.
Concrete, the pump housing described in the utility model, impeller, pump cover, pump shaft, mechanical sealing assembly, aseptic tank and motor all can adopt known technology of the prior art, about the pump housing, impeller, pump cover, pump shaft, mechanical sealing assembly, aseptic tank and motor known solution in the prior art, those of ordinary skill in the art all knows, so do not repeat them here.
Working principle of the present utility model is: feed sterile air in aseptic tank, sterile air is isolated with the extraneous passage that communicates with the bacterium that exists between pump shaft and pump cover and the mechanical sealing assembly, makes centrifugal pump realize aseptic completely conveying.
The utility model and prior art contrast, because on the aseptic centrifugal pump of pipe type, be provided with aseptic tank, after feeding sterile air in the aseptic tank, sterile air is isolated with the extraneous passage that communicates with the bacterium that exists between pump shaft and pump cover and the mechanical sealing assembly, the aseptic material of conveying is isolated from the outside fully, thereby reaches the purpose of aseptic conveying.
