Description

Technical Field

[0001] This application relates to the technical field of magnetic drive stirring equipment, specifically an energy-saving magnetic drive stirrer. Background Technology

[0002] In the production processes of industries such as chemical, pharmaceutical, and food, mixing various raw materials and intermediates is an indispensable and crucial step. Magnetic stirrers, as the equipment that performs this operation, rely on their non-contact transmission technology, and their performance indicators are directly related to important production parameters such as the uniformity of material mixing, production efficiency, and the overall energy consumption level.

[0003] For example, patent CN221637868U discloses a magnetically driven stirrer, including a fixed cover, a tank, a support frame, a magnetically driven stirrer body, a support assembly, and a clamping assembly. The beneficial effect of this invention is that, through the cooperation of the clamping assembly and the support assembly, the stirring of liquid inside the tank using the rotating shaft and stirring blades is more stable, and the tank is less prone to shaking when impacted by the liquid, thus reducing the likelihood of tilting or even tipping over.

[0004] However, the magnetic drive stirrer of the above patent is not convenient for cleaning the inside of the equipment. After long-term use, material residue is easily left on the inner wall, top and surface of the stirring components of the tank. This not only affects the purity and mixing effect of the subsequent stirring materials, but also requires manual disassembly and cleaning, which increases maintenance costs and operation difficulty. Therefore, it is necessary to provide an energy-saving magnetic drive stirrer to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide an energy-saving magnetic drive stirrer, which solves the problems of the above-mentioned patents, such as the inconvenience of cleaning the inside of the equipment, the easy retention of material residue after long-term use affecting the subsequent stirring effect, and the need for manual disassembly and cleaning, which increases maintenance costs.

[0007] The technical solution adopted by this application to solve its technical problem is: an energy-saving magnetic drive stirrer, comprising:

[0008] A mixing tank, the upper part of which is equipped with a top cover;

[0009] A stirring assembly, which is installed on the top cover, is adapted to stir the materials in the stirring tank;

[0010] A cleaning assembly is mounted on the top cover. The cleaning assembly includes a ring pipe mounted on the top cover, with multiple first water spray nozzles connected to the ring pipe facing the top cover. The ring pipe is also connected to multiple second water spray nozzles facing the mixing tank. A water pump is mounted on the top cover, and a water pipe is installed at the outlet of the water pump. One end of the water pipe extends into the top cover and communicates with the ring pipe.

[0011] Furthermore, the stirring assembly includes a rotating rod that is driven by a power source and rotatably connected to the top cover. One end of the rotating rod is equipped with an upper scraper, and the upper scraper has an upper scraping surface that is adapted to the top of the inner part of the top cover.

[0012] Multiple intermediate plates are installed on the rotating rod, and a side scraper is installed at one end of each intermediate plate. The side scraper has a side scraping surface adapted to the inner wall of the mixing tank.

[0013] Furthermore, the other end of the rotating rod is equipped with two sets of stirring blades located at the bottom of the mixing tank.

[0014] Furthermore, a bracket is installed on the top cover, and a magnetic stirrer is installed on the bracket. The output end of the magnetic stirrer extends into the top cover and is connected to one end of the rotating rod.

[0015] Furthermore, the top cover is connected to a liquid inlet pipe, and a sealing cap is installed at one end of the liquid inlet pipe.

[0016] Furthermore, the lower part of the mixing tank is equipped with multiple sets of support legs, and the lower end of each support leg is equipped with an anti-slip pad.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0031] like Figure 1 and Figure 2As shown, this application provides an energy-saving magnetic drive stirrer, including a stirring tank 1. The stirring tank 1 serves as a container for material stirring, playing a crucial role in containing the material to be stirred and providing space for the stirring process. To ensure its stability during operation, multiple sets of support legs 11 are fixedly installed on the lower part of the outer wall of the stirring tank 1. Anti-slip pads (not shown in the figure) are fixedly installed at the lower end of the support legs 11. These support legs 11 are arranged in a uniform distribution, providing reliable support for the stirring tank 1 from multiple directions, allowing the stirring tank 1 to be placed stably in various work sites. At the same time, a drain valve pipe 12 is connected to the central part of the lower part of the stirring tank 1. The drain valve pipe 12 has a dual function: on the one hand, after stirring is completed, the stirred material can be discharged through it to realize the collection and transfer of material; on the other hand, when cleaning the stirrer, it can be used to discharge cleaning water, making subsequent operation processes smoother and more convenient.

[0032] A top cover 2 is installed on the upper part of the mixing tank 1 via a flange. The flange connection makes it easy to disassemble the top cover 2 from the mixing tank 1. When it is necessary to maintain the inside of the mixing tank 1, such as checking the operation of the mixing parts or performing deep cleaning inside the tank, the operator can easily open the top cover 2, which provides convenience for internal operations. A liquid inlet pipe 21 is connected to the top cover 2. The liquid inlet pipe 21 is the channel for adding the material to be mixed into the mixing tank 1. The material is transported into the mixing tank 1 through the liquid inlet pipe 21. In order to prevent the material from splashing out of the liquid inlet pipe 21 due to the rotation of the mixing parts during the mixing process, a sealing cap 22 is threadedly connected to one end of the liquid inlet pipe 21. The sealing cap 22 can tightly seal the liquid inlet pipe 21 to form a relatively sealed space, ensuring the stable operation of the mixing process.

[0033] A bracket 23 is fixedly installed in the center of the top of the top cover 2. A magnetic stirrer 24 is installed on the bracket 23 by bolts. The bolt connection facilitates the installation and disassembly of the magnetic stirrer 24. When the magnetic stirrer 24 malfunctions and needs to be repaired, or when it needs to be replaced with a magnetic stirrer of a different specification to meet different stirring needs, the operator can disassemble it, which facilitates the later maintenance and replacement work.

[0034] like Figures 3-5 As shown, a stirring assembly 3 is installed on the top cover 2. The stirring assembly 3 is the part that realizes the stirring of materials. The stirring assembly 3 includes a rotating rod 31 coaxially installed on the output end of the magnetic stirrer 24. When the magnetic stirrer 24 is powered on and started by the corresponding controller, it will generate power and drive the rotating rod 31 to rotate through the output end. The rotating rod 31 is located inside the stirring tank 1 and is the power transmission component of the entire stirring assembly 3, which transmits the power of the magnetic stirrer 24 to other stirring components.

[0035] An upper scraper 32 is bolted to one end of the rotating rod 31. The upper scraper 32 is mainly used to clean the top inside the top cover 2. During the mixing process, some materials may adhere to the top inside the top cover 2 due to splashing or other reasons. If not cleaned in time, it will affect the purity of the materials to be mixed later. The upper scraper 32 has an upper scraping surface 321 that is adapted to the top inside the top cover 2. This design allows the upper scraper 32 to fit better against the top inside the top cover 2. When the rotating rod 31 drives the upper scraper 32 to rotate, the upper scraping surface 321 can more effectively scrape off the residual materials on the top inside the top cover 2.

[0036] Multiple intermediate plates 33 are fixedly installed on the rotating rod 31. The intermediate plates 33 rotate synchronously with the rotating rod 31. During the rotation, they can stir the material in the middle of the mixing tank 1. The middle of the mixing tank 1 is the area where the material is more concentrated. The stirring action of the intermediate plates 33 can ensure that the material is fully mixed in the middle area, preventing uneven mixing of the material in the middle. A side scraper 34 is fixedly installed on one end of each intermediate plate 33. The side scraper 34 is suitable for cleaning the inner wall of the mixing tank 1, which can reduce the material adhering to the tank wall. The side scraper 34 has a side scraping surface 341 adapted to the inner wall of the mixing tank 1. The height adaptation between the side scraping surface 341 and the inner wall of the mixing tank 1 ensures that the side scraper 34 can effectively scrape off the material on the tank wall during the rotation, improve the cleanliness of the tank wall, and create good conditions for the next stirring.

[0037] Two sets of stirring blades 35 are fixedly installed at the other end of the rotating rod 31, located at the bottom of the mixing tank 1. The stirring blades 35 rotate synchronously under the drive of the rotating rod 31, which can stir the material at the bottom of the mixing tank 1. The bottom of the mixing tank 1 is where the material is prone to settle. The rotation of the stirring blades 35 can make the material at the bottom fully stirred, so that the material can be mixed evenly in the bottom area, thereby ensuring that the material in the entire mixing tank 1 can be fully stirred and improving the overall stirring effect.

[0038] like Figures 2-5 As shown, a cleaning component 4 is installed on the top cover 2. This cleaning component 4 is used to clean the inner wall of the mixing tank 1 and the inner top of the top cover 2 after mixing, to prevent residual materials from affecting the mixing effect of the next mixing. The cleaning component 4 includes a ring pipe 41 that is bolted to the inner wall of the top cover 2. The ring pipe 41 is a transmission pipe for cleaning water, which can evenly distribute the cleaning water to each spraying part. In order to evenly spray the cleaning water to the parts that need to be cleaned, multiple first spray nozzles 42 are connected to the ring pipe 41. The spray angle of the first spray nozzles 42 is adapted to the inner top of the top cover 2, so that the water sprayed by the first spray nozzles 42 can cover multiple areas of the inner top of the top cover 2 for efficient cleaning.

[0039] Meanwhile, multiple second water spray nozzles 43 are connected to the ring pipe 41. The spray angle of the second water spray nozzles 43 is adapted to the inner wall of the mixing tank 1, so that the water sprayed from the second water spray nozzles 43 can be sprayed onto the inner wall of the mixing tank 1, cleaning the tank wall from top to bottom in multiple directions and ensuring the cleanliness of the tank wall.

[0040] A water pump 44 is bolted to the upper surface of the top cover 2. The water pump 44 is the power source of the cleaning component 4. After being powered on, it is started by the corresponding controller to provide power for the cleaning water, which is used to transport the cleaning water from the external water source to the ring pipe 41. A detachable water pipe 45 is installed at the outlet of the water pump 44. The water pipe 45 connects the water pump 44 and the ring pipe 41. One end of the water pipe 45 extends into the top cover 2 and is connected to the ring pipe 41. To facilitate the installation and removal of the water pipe 45, a detachable design is adopted. When the water pipe 45 is damaged or needs to be replaced, the operator can perform the replacement operation. A detachable liquid inlet head 46 is installed at the suction port of the water pump 44. The liquid inlet head 46 is used to connect to the external cleaning water source. The detachable design also facilitates the replacement and maintenance of the liquid inlet head 46, making the maintenance of the entire cleaning component 4 simpler.

[0041] Specifically, when stirring is required, the operator first opens the sealing cap 22 and adds the material to be stirred into the stirring tank 1 through the liquid inlet pipe 21. During the addition process, the amount of material added can be controlled as needed. After the addition is completed, the sealing cap 22 is closed to prevent the material from splashing out during subsequent stirring. Then, the magnetic stirrer 24 is started. The magnetic stirrer 24 drives the rotating rod 31 to rotate through magnetic field transmission. When the rotating rod 31 rotates, the lower stirring blades 35 begin to stir the material at the bottom of the stirring tank 1. This ensures that the material at the bottom is fully agitated. Multiple intermediate plates 33 and side scrapers 34 rotate with the rotating rod 31. The side scraping surface 341 of the side scraper 34 is adapted to the inner wall of the mixing tank 1, which can stir and scrape the material on the inner wall of the mixing tank 1, reducing the material residue on the tank wall. At the same time, the upper scraping surface 321 of the upper scraper 32 is adapted to the top of the top cover 2, which scrapes the material on the top of the top cover 2. Through the combined action of each component, the material in the entire mixing tank 1 can be fully and evenly stirred, meeting the production requirements for material mixing.

[0042] After mixing is complete, the operator opens the drain valve 12 to discharge the mixed material and collect it. If cleaning of the mixing tank 1 and the top cover 2 is required, the operator connects the inlet head 46 to an external cleaning water source and starts the water pump 44. The water pump 44 delivers cleaning water to the ring pipe 41 through the water pipe 45. The first spray nozzle 42 on the ring pipe 41 sprays water to the top inside the top cover 2 for cleaning, and the second spray nozzle 43 sprays water to the inner wall of the mixing tank 1 for cleaning. During the cleaning process, in order to achieve a more thorough cleaning effect, the magnetic stirrer 24 can be restarted to make the rotating rod 31 rotate slowly, driving the upper scraper 32 and the side scraper 34 to rotate. At this time, the rotating upper scraper 32 and the side scraper 34 can work with the water flow to perform a deeper cleaning of the top inside the top cover 2 and the tank wall, removing the residual material. After cleaning is completed, the water pump 44 and the magnetic stirrer 24 are turned off, and the drain valve 12 is opened to discharge the cleaning water. Thus, the entire cleaning process is completed.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
