Description

Technical Field

[0001] This utility model relates to the field of physical experiments, and in particular to a physical experiment stirring device that can scrape the wall. Background Technology

[0002] In the field of physics experiments, stirring devices are indispensable key equipment, widely used in various experimental scenarios involving the mixing of materials and solvents. Whether it is the uniform mixing of different chemical substances in chemical synthesis experiments to promote the full chemical reaction, or the stirring of various powders, granular materials and liquid solvents in materials science experiments to prepare materials with specific properties, stirring devices play a vital role.

[0003] A physical experiment mixing device with a wall-scraping function, disclosed in CN222173916U, includes a mixing tank, a discharge port, a tank cover, and a feeding hopper. The top of the mixing tank has a connection hole. While mixing, the device uses a scraper and a cleaning brush to scrape off the material adhering to the inner wall of the mixing tank, preventing solid material from accumulating on the tank wall and forming sediment or clumps. However, although the device uses a motor and an electric push rod to drive the mixing rod, scraper, and cleaning brush to rotate and move, it cannot transport the material. Some material will still adhere to the inner wall. Moreover, the use of multiple power components not only increases the experimental cost but also increases the energy consumption and operating cost of the equipment, affecting the efficiency of the experiment and cleaning.

[0004] Therefore, it is necessary to design a physical experimental stirring device that can simultaneously stir, mix, and transport materials and solvents while scraping off the material on the inner wall, reducing the need for power components, lowering experimental costs, preventing material adhesion, reducing cleaning difficulty, and improving experimental and cleaning efficiency. Utility Model Content

[0005] To overcome the shortcomings of the current device, which uses a motor and electric push rod to drive the stirring rod, scraper, and cleaning brush to rotate and move, achieving material stirring and scraping, but cannot transport the material, some material still adheres to the inner wall, and the use of multiple power components not only increases experimental costs but also increases the energy consumption and operating costs of the equipment, affecting the efficiency of experimentation and cleaning, this utility model provides a physical experimental stirring device that can stir, mix, and transport materials and solvents while scraping off the material on the inner wall, reducing the number of power components, lowering experimental costs, preventing material adhesion, reducing cleaning difficulty, and improving experimental and cleaning efficiency.

[0006] The technical implementation scheme of this utility model is as follows: a physical experiment stirring device capable of scraping the wall, comprising a conical stirring chamber, a crushing chamber, a crushing frame, a protective cover, a stirring head, a partition, a second motor, a scraping component, and a discharge component. The crushing chamber is connected to the upper side of the conical stirring chamber, and the crushing frame is rotatably connected to the middle of the crushing chamber. The protective cover is threadedly connected to the upper part of the crushing frame, and the stirring head is connected to the outer side of the crushing frame. The partition is connected to the lower part of the crushing chamber, and the second motor is connected to the lower part of the conical stirring chamber. The second motor and the processor are electrically connected through a control module. The output shaft of the second motor passes through the conical stirring chamber and is connected to the crushing frame. The crushing frame is equipped with a scraping component for scraping off sticky materials, and the lower left part of the conical stirring chamber is equipped with a discharge component for discharging materials.

[0007] Optionally, the diameter of the upper part of the conical mixing chamber is larger than the diameter of the lower part.

[0008] Optionally, the partition has two discharge ports.

[0009] Optionally, the scraping assembly includes a connecting rod, a scraper head, and a threaded column. The threaded column is threadedly connected to the middle of the crushing frame, and the connecting rod is rotatably connected to the lower part of the threaded column. The connecting rod is slidably connected to the crushing frame, and the scraper head is connected to the left side of the connecting rod. The scraper head contacts the conical mixing chamber.

[0010] Optionally, it also includes an adjusting block, which is connected to the upper side of the threaded column.

[0011] Optionally, the discharge assembly includes a first motor, a discharge pipe, and a baffle plate. The first motor is connected to the lower left part of the conical mixing chamber. The first motor and the processor are electrically connected through a control module. The discharge pipe is connected to the lower left side of the conical mixing chamber. The baffle plate is connected to the output shaft of the first motor and contacts the discharge pipe.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention allows materials and solvents to flow into a conical mixing chamber. The mixing head rotates to mix the materials and solvents, and drives the connecting rod and scraper head to rotate to scrape off the materials on the inner wall and transport the materials. This allows the materials and solvents to be mixed and transported while the materials on the inner wall are scraped off, reducing the number of power components, lowering experimental costs, preventing material adhesion, reducing cleaning difficulty, and improving experimental and cleaning efficiency.

[0013] 2. This utility model allows for the removal of the protective cover by rotating it. Then, the threaded column is rotated by the adjusting block. The threaded column moves under the action of the thread, which drives the connecting rod and the scraper head to move for fine adjustment. After adjustment, the protective cover is installed and the device is used again. This allows for fine adjustment of the position of the connecting rod and the scraper head to adjust the tightness for scraping materials. It is suitable for scraping materials of different viscosities and is flexible and convenient to use. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0022] A physical experimental stirring device capable of scraping the walls, such as... Figures 1-6 As shown, the device includes a conical mixing chamber 1, a crushing chamber 2, a crushing frame 3, a protective cover 4, a mixing head 5, a partition 10, a second motor 14, a scraping assembly, and a discharge assembly. The upper diameter of the conical mixing chamber 1 is larger than the lower diameter. The crushing chamber 2 is connected to the upper side of the conical mixing chamber 1. The crushing frame 3 is rotatably connected to the middle of the crushing chamber 2. The protective cover 4 is threadedly connected to the upper part of the crushing frame 3. The mixing head 5 is connected to the outer side of the crushing frame 3. The partition 10 is connected to the lower part of the crushing chamber 2. The partition 10 has two discharge ports to facilitate material entry. The second motor 14 is connected to the lower middle part of the conical mixing chamber 1. The second motor 14 and the processor are electrically connected through a control module. The output shaft of the second motor 14 passes through the conical mixing chamber 1 and is connected to the crushing frame 3. The crushing frame 3 is equipped with a scraping assembly for scraping off sticky materials. The discharge assembly for discharging materials is located at the lower left of the conical mixing chamber 1.

[0023] like Figure 3 , Figure 4 and Figure 5 As shown, the scraping assembly includes a connecting rod 6, a scraper head 7, and a threaded column 9. The threaded column 9 is threadedly connected to the middle of the crushing frame 3. The connecting rod 6 is rotatably connected to the lower part of the threaded column 9. The connecting rod 6 is slidably connected to the crushing frame 3. The scraper head 7 is connected to the left side of the connecting rod 6. The scraper head 7 contacts the conical mixing chamber 1. It also includes an adjusting block 8. The adjusting block 8 is connected to the upper side of the threaded column 9 to facilitate hand gripping and rotating the threaded column 9.

[0024] like Figure 6 As shown, the discharge assembly includes a first motor 11, a discharge pipe 12, and a baffle plate 13. The first motor 11 is connected to the lower left part of the conical mixing chamber 1. The first motor 11 and the processor are electrically connected through a control module. The discharge pipe 12 is connected to the lower left side of the conical mixing chamber 1. The baffle plate 13 is connected to the output shaft of the first motor 11 and is in contact with the discharge pipe 12.

[0025] This device can be used when materials need to be stirred in physical experiments. The conical mixing chamber 1 is placed in contact with the tabletop, with the upper diameter of the chamber larger than the lower diameter. The material is then poured into the crushing chamber 2. The processor starts the second motor 14 via the control module, which drives the crushing frame 3 to rotate and crush the material. The crushed material falls from the outlet on the partition 10 back into the conical mixing chamber 1. Solvent or water is then poured into the crushing chamber 2, allowing the solvent to flow into the conical mixing chamber 1 from the outlet. Simultaneously, the rotation of the crushing frame 3 drives the stirring head 5 to rotate, mixing the material and solvent. It also drives the connecting rod 6 and the scraper head 7 to rotate, scraping the material off the inner wall of the conical mixing chamber 1 and... The material is conveyed, which allows for the mixing and conveying of materials and solvents while simultaneously scraping off material from the inner wall. This reduces the need for power components, lowers experimental costs, prevents material adhesion, reduces cleaning difficulty, and improves experimental and cleaning efficiency. After mixing is complete, the first motor 11 is started, which drives the baffle plate 13 to rotate and disengage from the discharge pipe 12. Then, the first motor 11 is turned off. Under the action of the scraper head 7, the material is discharged from the discharge pipe 12 for collection and testing. Subsequently, the second motor 14 is turned off, and the device is cleaned. After cleaning, the first motor 11 is reversed, causing the baffle plate 13 to move in the opposite direction and reset to contact the discharge pipe 12 for sealing. Finally, the first motor 11 is turned off.

[0026] Before crushing, the protective cover 4 is moved and removed by rotating it. Then, the threaded column 9 is rotated by adjusting block 8. The threaded column 9 moves under the action of the thread, which drives the connecting rod 6 and the scraper head 7 to move for fine adjustment, so that the scraper head 7 fits more tightly with the conical mixing chamber 1. After adjustment, the protective cover 4 is brought into contact with the crushing frame 3, and then the protective cover 4 is rotated to move it for installation. Then, the second motor 14 drives the crushing frame 3 to rotate, so that the mixing head 5, connecting rod 6 and scraper head 7 rotate to mix the materials and scrape off the sticky materials. This allows for fine adjustment of the position of the connecting rod 6 and scraper head 7 to adjust the tightness for scraping off materials, making it easy to adapt to scraping off materials of different viscosities. It is flexible and convenient to use.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
