Description

Technical Field

[0001] This utility model relates to the technical field of preservative addition equipment, specifically a preservative addition device. Background Technology

[0002] Preservatives, also known as antimicrobial agents or freshness preservers, are chemical substances that can inhibit the growth and reproduction of microorganisms. They are commonly used in food, medicine, cosmetics, or biological specimens to slow down the spoilage of the corresponding products. Preservative addition equipment is required when adding preservatives.

[0003] A search revealed a patent, CN220534566U, which discloses a preservative adding device, comprising a preservative adding box and a storage box. The storage box is symmetrically and fixedly mounted with fixing rods, which are respectively fixedly installed on the inner wall of the preservative adding box. A lifting plate is movably installed through the upper end of the preservative adding box, and a metering box is fixedly installed at the lower end of the lifting plate. This invention, by providing a feeding pipe, adds preservative to the storage box within the preservative adding box. The preservative is stored in the storage box. When preservative needs to be added, an external control device can control the motor, causing the lifting plate to move up and down reciprocally. The preservative is then transported through a guide channel on the guide plate. This invention is characterized by its strong practicality and ability to add preservatives in a metered manner.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings: In reality, solid preservatives may clump together when left for a long time. When preservatives clump together over a large area, it becomes impossible to control the precise amount added, and it can also easily cause blockages in the preservative adding equipment. Therefore, there is an urgent need in this field to improve the preservative adding equipment in order to solve the shortcomings of the existing technology. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1 Please see Figures 1-5 A preservative addition device includes a storage tank 1 located on one side of a mixing device. A connecting frame 2, communicating with the interior of the mixing device, is located below the storage tank 1. A feed pipe 3 is fixedly installed between the storage tank 1 and the connecting frame 2. A drive motor 4 with forward and reverse rotation is fixedly installed on the upper part of the storage tank 1. A rotating shaft 5 extending into the feed pipe 3 is fixedly installed at the output end of the drive motor 4. Several stirring blades 6 are fixedly installed on the inner side of the rotating shaft 5 within the storage tank 1. A conveying auger 18 is fixedly installed on the side of the rotating shaft 5 within the feed pipe 3. A weighing platform 7, adapted to the position of the feed pipe 3, is located within the connecting frame 2. A main controller 8 for control is fixedly installed on the side of the drive motor 4. A pushing unit adapted to the weighing platform 7 and used for pushing is provided in the connecting frame 2. The pushing unit includes a first telescopic device 9 fixedly installed at one end of the connecting frame 2 and having a telescopic effect. The telescopic end of the first telescopic device 9 passes through one side of the connecting frame 2 and extends into the connecting frame 2. A push plate 10 adapted to the weighing platform 7 is fixedly installed at the telescopic end of the first telescopic device 9. A feeding port 13 communicating with its interior is provided on the upper part of the storage tank 1. A sealing cover 15 with a sealing effect is provided on the upper part of the feeding port 13. A connecting flange 17 is fixedly installed at one end of the connecting frame 2.

[0024] The specific implementation method in this embodiment is as follows: The connecting frame 2 is fixedly installed on the upper part of the mixing device by fasteners and connecting flange 17. The upper side of the mixing device has a through hole that matches the internal cavity of the connecting frame 2. The preservative to be added is placed in the storage tank 1 through the feeding port 13 and the sealing cover 15 is closed. When no preservative is needed, the drive motor 4 is started by the main controller 8. The output of the drive motor 4 drives the rotating shaft 5 to rotate forward. The rotating shaft 5 drives the stirring blades 6 and the conveying auger 18 to rotate. The gap of the conveying auger 18 is adapted to the size of the preservative particles. When the conveying auger 18 rotates forward, it cannot convey the preservative downward. The stirring blades 6 rotate slowly to prevent the preservative from clumping. When preservative needs to be added to the mixing device, the drive motor 4 is reversed by the main controller 8 and the weighing platform 7 is turned on. The weighing platform 7 is a prior art technology. The device is designed to weigh the preservative. The rotating shaft 5 reverses, causing the conveying auger 18 to reverse as well. When the auger 18 reverses, the preservative in the storage tank 1 is conveyed through the discharge pipe 3 to the connecting frame 2, and the preservative is placed on the weighing platform 7. The weight of the preservative to be added is set by the main controller 8. When the weight threshold is reached, the rotating shaft 5 rotates forward to stop the preservative from falling. Then, the first telescopic device 9 is activated. The telescopic end of the first telescopic device 9 drives the push plate 10 to move, pushing the preservative on the weighing platform 7 into the mixing device, achieving the effect of quantitative preservative addition. Simultaneously, the stirring blades 6 effectively prevent the preservative in the storage tank 1 from clumping, improving the weight accuracy of preservative addition. Furthermore, the conveying auger 18 reduces the risk of blockage in the preservative addition device.

[0025] Example 2 Please see Figure 2 and Figure 4 This embodiment includes the above embodiment, and further includes: a baffle 11 that is adapted to the connecting frame 2 and extends into the connecting frame 2 is inserted into the upper part of the connecting frame 2, the baffle 11 is adapted to the weighing platform 7, and a second telescopic device 12 with telescopic effect is fixedly installed on the upper part of the connecting frame 2, and the upper telescopic end of the second telescopic device 12 is fixedly installed on the upper side of the baffle 11.

[0026] In this embodiment, the baffle 11 serves to separate and seal the connecting frame 2 from the mixing device. At the same time, the baffle 11 blocks the position of the preservative when it falls, ensuring that the preservative after the feed pipe 3 falls onto the weighing platform 7, thus improving the accuracy of weighing the preservative. When it is necessary to push the preservative, the second telescopic device 12 is activated. The telescopic end of the second telescopic device 12 rises, driving the baffle 11 to rise, thereby pushing the preservative on the weighing platform 7 into the mixing device.

[0027] Example 3 Please see Figure 2 and Figure 5 This embodiment includes all the above embodiments, and further includes: a viewing window 14 is provided on the side of the storage tank 1. The viewing window 14 is transparent, which facilitates observation of the situation inside the storage tank 1. A rotating shaft 5 is located on the inner side of the storage tank 1 and several rotating frames 16 are fixedly installed. The rotating frames 16 abut against the inner wall of the storage tank 1 to prevent the preservative from sticking to the inner wall of the storage tank 1. The lower part of the storage tank 1 is shaped like a frustum with a wider top and a narrower bottom, which facilitates the complete output of the preservative inside the storage tank 1. Several stirring blades 6 are fixedly installed between the rotating frames 16 and the rotating shaft 5 to improve the connection strength of the stirring blades 6.
