In order to overcome the defects, the utility model provides the stirring blade capable of preventing the container from being scratched, which comprises at least two blades and a circular protective outer ring arranged in the circumferential direction of the blades, the roots of the blades are connected with each other through a connecting central table top, and the connecting central table top is connected with the circular protective outer ring. And the tip part of each paddle blade is connected with the protective outer ring. According to the technical scheme, the circular protective outer ring is arranged on the outer side of the stirring paddle, so that the stirring paddle cannot be cut with a container on the outer side when the position of the stirring paddle deviates, and the stirring container is effectively protected.

Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to a stirring blade which can prevent a container from being scratched. Background Art

[0002] Stainless steel agitator blades are used in a wide range of industries, including chemical, pharmaceutical, water treatment, metallurgy, scientific research, and food. Agitators are important stirring devices, primarily used for mixing and stirring various liquids and solids. Choosing the right agitator blade ensures optimal stirring. The appropriate agitator blade should be selected based on the physical properties, volume, and purpose of the medium. This ensures a more even mixture, significantly accelerating reaction speed and improving production efficiency. Because existing agitators rely primarily on motors and containers to maintain their position, the reverse thrust of the material during stirring can cause the agitator blades to shift, scraping against the container walls or even breaking the container.

[0003] In view of the above-mentioned defects, the inventors of the present invention finally obtained the present invention after a long period of research and practice. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a stirring blade that prevents scratching of the container, including a paddle blade and a circular protective outer ring arranged around the paddle blade. There are at least two paddle blades, and the roots of the paddle blades are connected to each other through a connecting center table, and the tip of each paddle blade is connected to the protective outer ring.

[0005] The stirring blade's protective outer ring ensures that when the blade rotates at high speed and becomes misaligned, the outer ring contacts the container wall, exerting force and deflecting the entire stirring blade in the opposite direction. Because the protective outer ring is circular, its contact with the outer wall is gentler than that of the stirring blade, effectively protecting the container from scratches and extending its lifespan. The stirring blade in this novel solution is available in both magnet and stirrer versions, both of which provide excellent container protection.

[0006] Preferably, a rubber or silicone anti-collision gasket is provided on the outer circumference of the protective outer ring.

[0007] Soft anti-collision washers can better protect the container wall.

[0008] Preferably, the anti-collision gasket is provided with a plurality of scrapers made of rubber or silicone extending radially outward in the circumferential direction.

[0009] The soft scraper on the anti-collision washer not only reduces shock and protects the container wall during impact, but also reduces the contact area between the anti-collision washer and the container wall during impact, which can effectively reduce friction. At the same time, the scraper can also scrape off the solute adhering to the container wall, further improving the stirring efficiency.

[0010] Preferably, the connecting center table is designed to protrude downward, with the protruding height being higher than the height of the paddle blades, and a magnet is provided inside the connecting center table.

[0011] Conventional magnetic stirring blades are more prone to misalignment and are often shaped like capsules to protect the container, but this results in lower stirring efficiency. This novel solution incorporates a magnet inside the central platform, enabling rapid stirring through magnetic force changes. This protects the container while maintaining the high stirring efficiency of the blades, enabling efficient magnetic stirring of low-viscosity liquids.

[0012] Preferably, the stirring blade is also equipped with a stirring rod, and a connection hole for detachably connecting the stirring rod is provided in the middle of the connecting center table.

[0013] The stirring rod mode in this solution allows the container to be well protected when stirring with a conventional stirring rod.

[0014] Preferably, the protective outer ring is a hard protective outer ring.

[0015] The hard outer ring can reduce stirring resistance and improve stirring efficiency.

[0016] Preferably, the protective outer ring is rigidly connected to the tip of each blade via a connecting rod.

[0017] Hard connection can also reduce stirring resistance and improve stirring efficiency.

[0018] Preferably, the protective outer ring is connected to the tip of each blade via a detachable connecting rod.

[0019] The detachable connection allows the use of a single protective outer ring to adapt to stirring paddle blades of different shapes, further saving the user's expenses.

[0020] The beneficial effects of the utility model are as follows:

[0021] The technical solution of the utility model provides a circular protective outer ring on the outer side of the stirring blade, so that when the stirring blade is offset, it will not be cut by the outer container, thereby effectively protecting the stirring container.

[0026] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] like Figure 1 As shown, embodiment 1 of the present invention provides a stirring blade for preventing a container from being scratched, comprising a paddle blade 1 and a circular protective outer ring 2 arranged on the circumference of the paddle blade. The stirring blade in this embodiment is provided with three fan-shaped paddle blades 1, the roots of the paddle blades are interconnected by a connecting center table 3, and the tip of each paddle blade is connected to the protective outer ring through a hard connecting rod 5. The stirring blade is also equipped with a stirring rod, and a connecting hole 4 for detachably connecting the stirring rod is provided in the middle of the connecting center table 3. The protective outer ring 2 is a hard protective outer ring. The protective outer ring is rigidly connected to the tip of each paddle blade through a connecting rod 5.

[0029] Example 2

[0030] like Figure 2 As shown, Example 2 of the present invention differs from Example 1 in the number and shape of the paddle blades, demonstrating the applicability of this technical solution to various stirring paddle blade heights. In Example 2, there are four stirring blades, evenly distributed around the connecting center table, and the paddle blades are rectangular.

[0031] Example 3

[0032] Example 3, based on Example 1 or 2, features a silicone anti-collision gasket circumferentially disposed on the outer side of the protective outer ring 2. The anti-collision gasket has several silicone scrapers extending radially outward from the circumference. The silicone material can also be replaced with a similarly elastic rubber material.

[0033] Example 4

[0034] Unlike Examples 1 and 2, Example 4 lacks a central connection hole in the center of the connecting platform 3, preventing the connection of a connecting rod. Instead, the connecting platform 3 protrudes downward, its height exceeding the height of the paddle blades 1. A magnet is located within the connecting platform 3. This design satisfies the requirements of magnetic stirring.

[0035] Example 5

[0036] Based on any one of the technical solutions in Examples 1-4, the protective outer ring of the stirring blade in Example 5 is connected to the tip of each blade via a detachable connecting rod. This allows one protective outer ring to protect stirring blades of various shapes and types, which is more economical.

[0037] The technical solution of the utility model provides a circular protective outer ring on the outer side of the stirring blade, so that when the stirring blade is offset, it will not be cut by the outer container, thereby effectively protecting the stirring container.

[0038] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
