Description

Novel mechanical seal suitable for aseptic product

Technical Field

The utility model belongs to the technical field of mechanical seal, in particular to novel mechanical seal who is fit for aseptic product to use.

Background

At present, the producer of production aseptic product, the reation kettle mechanical seal who uses are mostly traditional double mechanical seal, and this mechanical seal is used for the production of aseptic product, has inherent defect, mainly shows: 1. the debris foreign matters generated by the abrasion of the mechanical seal end surface drop in the collecting tank and cannot be cleaned, and the risk of introducing the foreign matters into the sterile product possibly exists due to the flowing of air flow in the production process; 2. during sterilization, a small amount of liquid is accumulated in the collecting tank, and due to insufficient steam penetrability, sterilization failure is possibly caused, and the risk of bacteria exists; 3. after the sealing end face of the mechanical seal is worn due to failure, the seal is damaged, and sterile unqualified cooling media in the cooling system enter the reaction kettle, so that the visibility of the seal damage is not strong, and large-area sterile product pollution is caused. We have therefore proposed a new type of mechanical seal suitable for use with sterile products to address the above problems.

SUMMERY OF THE UTILITY MODEL

The utility model provides a be convenient for clear up the collecting vat, be favorable to the sterilization and can carry out the novel mechanical seal that a suitable aseptic product that detects to sealed leakage used.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a novel mechanical seal who is fit for aseptic product to use, includes base, flange and collecting vat, the collecting vat sets up on the base, be provided with the washing mouth in the base, the collecting vat is through wasing mouth and washing pipeline intercommunication, be provided with a plurality of valves on the washing pipeline, be provided with the cooling jacket between base and the flange, be provided with gaseous detection device on the cooling jacket.

The washing mouth is including wasing the entry and wasing the export, wash the pipeline and include entry pipeline and outlet conduit, the collecting vat is through wasing entry and entry pipeline intercommunication, and through wasing export and outlet conduit intercommunication.

The gas detection device is connected with the alarm device.

The cleaning pipeline is communicated with a sterilization pipeline, and a sterilization control valve is arranged on the sterilization pipeline.

The sterilizing pipeline is arranged between the cleaning opening and the valve.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the collecting tank is communicated with the cleaning pipeline through the cleaning port, and cleaning liquid is introduced into the cleaning pipeline, so that the collecting tank is convenient and reliable to clean and has good repeatability;

2. the gas detection device is arranged on the cooling jacket and connected with the alarm device, when the mechanical sealing section leaks due to abrasion or other reasons, the alarm can be triggered at the first time, so that workers can find the leakage in time and overhaul or replace the mechanical sealing device in time, and the pollution of sterile products is avoided;

3. wash pipeline and sterilization pipeline intercommunication, the last sterilization control valve that is provided with of sterilization pipeline lets in the sterilization medium in to the sterilization pipeline, possesses sterilization flowing back and evacuation function for there is not the hydrops in the collecting vat in the sterilization process, and the sterilization is thorough, and no dead angle can not be because of steam penetrability is not strong, causes the sterilization failure.

In addition, the novel mechanical sealing material is easy to obtain, simple to manufacture, convenient to operate and process, remarkable in effect, easy to popularize and good in economic and social benefits.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

Referring to fig. 1, a novel mechanical seal suitable for aseptic products, including base 1, flange 2 and collecting vat 3, collecting vat 3 sets up on base 1, is provided with washing mouth 4 in the base 1, and collecting vat 3 is provided with a plurality of valves through washing mouth 4 and washing pipeline intercommunication on the washing pipeline, and the valve includes first valve 51, second valve 52, third valve 61 and fourth valve 62, is provided with cooling jacket 7 between base 1 and the flange 2, is provided with gaseous detection device 71 on the cooling jacket 7, and gaseous detection device 71 sets up at cooling jacket 7 upper end inboard.

The cleaning opening 4 comprises a cleaning inlet and a cleaning outlet, the cleaning pipeline comprises an inlet pipeline 5 and an outlet pipeline 6, a first valve 51 and a second valve 52 are arranged on the inlet pipeline 5, a third valve 61 and a fourth valve 62 are arranged on the outlet pipeline 6, and the collecting tank 3 is communicated with the inlet pipeline 5 through the cleaning inlet and is communicated with the outlet pipeline 6 through the cleaning outlet.

The gas detection device 71 is connected to an alarm device 72. When the mechanical sealing section is leaked due to abrasion or other reasons, gas in the main body equipment enters the cooling jacket 7 through a leakage point, rises to reach the topmost end of the cooling jacket 7, contacts the gas detection device 71 arranged on the cooling jacket 7, and the gas detection device 71 transmits a signal for sensing the leaked gas to the alarm device 72 to trigger the alarm device 72 to generate light buzzing alarm or light or buzzing. The gas detection device 71 is installed according to the requirement of gas used in the reaction kettle, and if the reaction kettle uses nitrogen, the nitrogen detection device is used; if the compressed air is, the oxygen detection device is used; similarly, if the gas is other gas, the corresponding gas detection device 71 in the prior art is installed and selected.

The cleaning pipeline is communicated with the sterilizing pipeline 8, a sterilizing control valve is arranged on the sterilizing pipeline 8, and the sterilizing control valve comprises a first sterilizing control valve 81 and a second sterilizing control valve 82.

The sterilizing duct 8 is provided between the cleaning port 4 and the valves, and the sterilizing duct 8 may be provided between the first valve 51 and the second valve 52 and between the third valve 61 and the fourth valve 62, respectively.

In the new installation or production process of the mechanical seal, when the collecting tank 3 needs to be cleaned, the first valve 51, the second valve 52, the third valve 61 and the fourth valve 62 are respectively opened, then the first sterilization control valve 81 and the second sterilization control valve 82 are closed, then cleaning liquid is introduced into the cleaning pipeline, enters from the inlet pipeline 5 and then flows out from the outlet pipeline 6, and the cleaning of the collecting tank 3 is finished; during sterilization, the collection tank 3 and the apparatus main body are sterilized at the same time, the first valve 51 and the fourth valve 62 are closed, the third valve 61 and the second sterilization control valve 82 are opened, the second valve 52 and the first sterilization control valve 81 are slightly opened, and a sterilization medium is introduced into the sterilization pipeline 8, so that the mechanical seal sterilization is completed, and the second valve 52, the third valve 61, the first sterilization control valve 81 and the second sterilization control valve 82 are closed immediately after sterilization.
