Abstract
Description
Technical Field
[0001] This application relates to the technical field of aseptic filling, and particularly to an aseptic filling dispenser. Background Art
[0002] Aseptic filling refers to the cold (room temperature) filling of products under aseptic conditions, which is relative to the high-temperature hot filling method usually carried out under general conditions. When filling under aseptic conditions, all parts of the equipment that may cause microbial contamination of the product remain aseptic. Therefore, there is no need to add preservatives to the product, nor to perform post-sterilization after the product is filled and sealed, which can meet the requirements of a long shelf life while maintaining the taste, color, and flavor of the product.
[0003] In related technologies, an aseptic cold filling combination machine is a perfect combination of a perfusion machine, a pouring machine, a bottle rinsing machine, a filling machine, a capping machine, etc., and is a high-performance automated liquid packaging equipment. Empty bottles enter the disinfectant perfusion machine through the bottle inlet conveyor to sterilize the bottles, and then are dialed into the disinfectant pouring machine by a dial to drain the disinfectant, and then are dialed into the aseptic water bottle rinsing machine by a dial to wash the bottles, and then are dialed into the filling machine for filling, and then enter the capping machine. Finally, the packaged products are sent out by the bottle outlet conveyor for post-packaging processing. The filling machine is one of the important components of the aseptic cold filling combination machine, and the filling machine is composed of components such as filling transmission parts, filling dispensers, filling main liquid distribution chambers, and filling valve filling pipelines. Beverage products enter the filling dispenser through the feed pipeline, then enter the main liquid distribution chamber, and then through the main liquid distribution chamber, flow into the filling valve through each branch pipeline and then into the bottle for filling. The filling dispenser is a relatively important component in the filling part, and materials, CIP, medium protection, internal sterilization medium of the equipment, etc. are all realized through this component.
[0004] The mandrel of the filling dispenser is fixedly connected to the feed pipeline and does not rotate. Components such as the positioning seat and the mounting seat are fixed to the main liquid distribution chamber of the filling machine and rotate with the filling machine. In the above-mentioned existing aseptic filling dispenser, the blocking and sealing between the channels between the mandrel and the outer sleeve rotating parts are realized by five rubber seals. Two of the rotating seals block the steam channel from the product channel and the external environment. Another two of the rotating seals directly rub against the mandrel of the dispenser. Another double-lip oil seal seals the mandrel and the outer sleeve of the dispenser, making the double-lip oil seal in this structure directly rub against the mandrel of the dispenser. These five rubber seals directly rub against the mandrel of the dispenser, reducing the service life of the mandrel of the dispenser. The cost of the mandrel of the dispenser is relatively expensive, and the service life of the five rubber seals themselves is also relatively low, thereby reducing the service life of the aseptic filling dispenser. Therefore, we propose an aseptic filling dispenser to solve the above problems. Utility Model Content

[0020] The technical solutions of the present application will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without making creative efforts belong to the scope of protection of the present application.
[0021] See Figure 1 and Figure 2 , the present application provides an aseptic filling dispenser, including a distributor mandrel 1, an outer sleeve 2, a mounting seat 3 and a double-lip shaft seal 6. The outer sleeve 2 is sleeved on the distributor mandrel 1, the mounting seat 3 is detachably installed and fixed on the top of the outer sleeve 2 through a screw three 20, and the top end of the distributor mandrel 1 extends into the mounting seat 3, wherein:
[0022] A mechanical shaft seal 4 is fixedly connected between the top end of the dispenser mandrel 1 and the mounting seat 3. By using the mechanical shaft seal 4, an effective seal can be achieved between the dispenser mandrel 1 and the mounting seat 3, thus replacing the original rubber sealing method. The service life of the mechanical shaft seal 4 is longer than that of the rubber sealing ring, and thus the sealing effect can be improved. A wear-resistant ring 5 is detachably fixedly sleeved on the dispenser mandrel 1 through a set screw 7. A double-lip shaft seal 6 is rotatably sleeved on the outer wall of the wear-resistant ring 5. By using the wear-resistant ring 5, the friction between the double-lip shaft seal 6 and the dispenser mandrel 1 can be avoided, and thus the service life of the dispenser mandrel 1 can be effectively extended. The bottom of the outer sleeve 2 is detachably installed and fixed with a flange 8 through a screw 9. The flange 8 is sleeved on the outer wall of the double-lip shaft seal 6. By using the flange 8, the gap between the double-lip shaft seal 6 and the outer sleeve 2 can be sealed. A bearing 15 and a bearing 16 are fixedly installed between the dispenser mandrel 1 and the outer sleeve 2. The bearing 15 is located above the double-lip shaft seal 6, and the bearing 16 is located above the bearing 15. By using the bearing 15 and the bearing 16, the stability of the relative rotation between the dispenser mandrel 1 and the outer sleeve 2 can be improved.
[0023] In this embodiment, a feed pipe 10 is detachably fixedly connected to the bottom end of the dispenser mandrel 1. A discharge port 11 communicating with the dispenser mandrel 1 is provided on the mounting seat 3. A steam inlet pipe 12 is detachably fixedly connected to the right side wall of the dispenser mandrel 1. A CIP inlet pipe 13 is detachably fixedly connected to the left side wall of the dispenser mandrel 1. A CIP discharge pipe 14 is fixedly connected to the left side wall of the mounting seat 3.
[0024] In this embodiment, two elastic retaining rings 17 are fixedly sleeved on the outer wall of the dispenser mandrel 1. Both of the two elastic retaining rings 17 are located between the bearing 15 and the bearing 16, and the two elastic retaining rings 17 are respectively in contact with the bearing 15 and the bearing 16. By using the two elastic retaining rings 17, the bearing 15 and the bearing 16 can be supported and fixed, so that the movement of the bearing 15 and the bearing 16 is more stable.
[0025] In this embodiment, a mounting sleeve 18 is sleeved on the outer wall of the dispenser mandrel 1. The mounting sleeve 18 is located above the bearing 16.
[0026] In this embodiment, the mounting sleeve 18 is detachably fixedly connected to the outer wall of the dispenser mandrel 1 through a screw 19.
[0027] In this embodiment, a mechanical shaft seal 21 is fixedly connected between the top of the mounting sleeve 18 and the mounting seat 3. By using the mechanical shaft seal 21, a further effective seal between the dispenser mandrel 1 and the mounting seat 3 can be achieved, thus replacing the original rubber sealing method. The service life of the mechanical shaft seal 21 is longer than that of the rubber sealing ring, and thus the sealing effect can be improved.
[0028] With the above structure, when the aseptic filling dispenser provided by the present application is in use, two mechanical seal structures, namely mechanical shaft seal 1-4 and mechanical shaft seal 2-21, are adopted to block and seal the steam channel and the CIP channel from the product channel and the external environment. Moreover, by adding a wear-resistant ring 5 at the lower seal of bearing 1-15, the frictional loss of the dispenser mandrel 1 can be effectively reduced, greatly extending its service life, and thus enhancing the service life of the aseptic filling dispenser.
[0029] The above has introduced in detail an aseptic filling dispenser provided by the present application. Specific embodiments are used herein to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present application, several improvements and modifications can still be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
