Description

Technical Field

[0001] The utility model relates to a bottom magnetic stirring device, belonging to the field of reaction tank accessories. Background Art

[0002] A reaction tank or fermentation tank refers to an industrial device used for microbial fermentation. It is a chemical reaction or physical reaction container. During its use, the materials that need to be fermented or reacted are initially put into the tank, which is then sealed and preserved. During the fermentation reaction, it is sometimes necessary to stir the materials that are already fermenting or reacting.

[0003] The existing application number is 202220720098.8, and the name of the patent application is a bird's nest pre-striping and cleaning device. It reveals that by using a magnetic stirrer as a stirring device, the water soaked with bird's nest is stirred during use, so that the bird's nest is gradually separated from the impurities therein, and the bird's nest is separated into strips to achieve automatic sorting. After sorting is completed, the bird's nest strips can be discharged through the catheter, and the impurities float on the water surface and are cleaned manually; the use of a magnetic stirrer can also reduce the introduction of external impurities and ensure quality.

[0004] Although the bird's nest itself will not adhere to the magnetic rotor, the colloid in the bird's nest will adhere to the magnetic rotor inside the equipment, affecting the fixation of the magnetic rotor inside the reaction tank, thereby affecting the speed of the magnetic rotor, or possibly causing the demagnetization effect of the magnetic rotor.

[0005] Therefore, the utility model provides a bottom magnetic stirring device with positioning and liquid drainage functions. Utility Model Content

[0006] In view of this, the purpose of the present invention is to provide a bottom magnetic stirring device with positioning and liquid drainage functions.

[0007] The utility model is achieved in this way:

[0008] A bottom magnetic stirring device comprises a tank body of a reaction tank, a magnetic rotor, a magnetic motor, and a positioning unit. The magnetic rotor is mounted on the bottom end of the tank body via the positioning unit, and a magnetic motor is mounted on the outside of the tank body corresponding to the magnetic rotor. The magnetic motor is used to drive the magnetic rotor to operate.

[0009] It also includes stirring blades, which are distributed in a circular array at equal distances on the top of the magnetic rotor.

[0010] As a further improvement, the positioning unit includes a first arc bar, a first arc block, and a second arc block;

[0011] The first arc strip, the first arc block, and the second arc block surround to form an annular structure. The magnetic rotor is accommodated inside the annular structure. The second arc block is located at the bottom end of the inner wall of the tank, while the first arc strip is located obliquely above. A number of first arc blocks are arranged between the first arc strip and the second arc block.

[0012] As a further improvement, it further includes a first liquid discharge port. The gaps between the first arc strip and the first arc block, between adjacent second arc blocks, and between the first arc block and the second arc block are the first liquid discharge ports.

[0013] As a further improvement, the arc width L2 of the first liquid discharge port is greater than the arc length L1 of the first arc block.

[0014] As a further improvement, the arc length of the first arc strip is greater than the arc length of the second arc block, and the arc length of the second arc block is greater than the arc length of the first arc block.

[0015] As a further improvement, the positioning unit includes a second arc strip and a third arc block. There are two second arc strips, which are respectively distributed on both sides of the third arc block to form a semi-circular structure. The third arc block is located on the inner bottom surface of the tank;

[0016] The magnetic rotor is placed in the semi-circular structure;

[0017] It further includes a second liquid discharge port. The gap between the second arc strip and the third arc block is the second liquid discharge port.

[0018] As a further improvement, the arc length L4 of the second arc strip is greater than the arc width L3 of the second liquid discharge port.

[0019] As a further improvement, the first arc strip, the first arc block, the second arc block, the second arc strip, and the third arc block are all fixed to the inner wall of the tank by welding.

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

[0021] ① The present utility model is positioned and restricted by the positioning unit. Since the bottom end inside the reaction tank is mostly arc-shaped, the magnetic rotor not located at the central position will not move downward due to its own gravity, playing a fixing role. Even when stirring viscous materials, liquid discharge treatment can be carried out through the positioning unit, avoiding the magnetic rotor being fixed insecurely, affecting the rotation speed of the magnetic rotor, and avoiding the demagnetization effect of the magnetic rotor.

[0022] ② There are two types of the positioning unit of the present utility model, both having two functions. One is to be a supporting object for the magnetic rotor to prevent the magnetic rotor from moving downward due to its own gravity in the case of being obliquely arranged. The other is that the liquid discharge port can prevent material accumulation, improving practicability. The liquid discharge ports include the first liquid discharge port and the second liquid discharge port. Description of the Drawings

[0033] Embodiment 1

[0034] Referring to Figures 1 - 6 As shown, this embodiment provides a specific implementation of a bottom magnetic stirring device, which includes a tank body 10 of a reaction tank, a magnetic rotor 20, a magnetic motor 30, and a positioning unit 50. The magnetic rotor 20 is installed at the inner bottom end of the tank body 10 through the positioning unit 50, and a magnetic motor 30 is installed outside the tank body 10 corresponding to the magnetic rotor 20. The magnetic motor 30 is used to drive the magnetic rotor 20 to operate;

[0035] It further includes a plurality of stirring blades 60, which are equally distributed at the top of the magnetic rotor 20 in a circular array.

[0036] In one specific implementation, the stirring blades 60 are fixed to the top of the magnetic rotor 20 by welding. Regardless of the amount of material loaded and the rotation speed, the stirring blades 60 will not detach from the magnetic rotor 20.

[0037] In one specific implementation, the sides of the stirring blades 60 are inclined, increasing the contact area with the material and improving the material mixing effect.

[0038] During the specific use process, the magnet rotor 20 and the stirring blade 60 assembled together are installed inside the reaction tank and positioned and restricted by the positioning unit 50. Since the bottom end inside the reaction tank is mostly arc-shaped, the magnet rotor 20 not set at the central position will not move downward due to its own gravity, playing a fixing role. Even when stirring viscous materials, drainage treatment can be carried out through the positioning unit 50, avoiding the insecure fixation of the magnet rotor 20, affecting the rotation speed of the magnet rotor 20, and avoiding causing the demagnetization effect of the magnet rotor.

[0039] Among them, the positioning unit 50 includes a first arc bar 501, a first arc block 502, and a second arc block 503;

[0040] The first arc bar 501, the first arc block 502, and the second arc block 503 surround to form an annular structure, and the magnet rotor 20 is accommodated inside the annular structure. The second arc block 503 for stably installing the magnet rotor 20 is located at the bottom end of the inner wall of the tank body 10, while the first arc bar 501 is located obliquely above, and a number of first arc blocks 502 are arranged between the first arc bar 501 and the second arc block 503.

[0041] Furthermore, the positioning unit 50 further includes a first drainage port 504, and the gaps between the first arc bar 501 and the first arc block 502, adjacent second arc blocks 503, and between the first arc block 502 and the second arc block 503 are the first drainage ports 504.

[0042] If there is material flowing through or adhering to the magnet rotor 20, the magnet rotor 20 serves as a supporting object on the one hand and can also prevent the accumulated liquid from increasing the rotational resistance of the magnet rotor 20 and affecting the rotation speed of the magnet rotor 20.

[0043] In one specific embodiment, the arc width L2 of the first drainage port 504 is greater than the arc length L1 of the first arc block 502, and the accumulated material liquid can be easily drained.

[0044] In one specific embodiment, the arc length of the first arc bar 501 is greater than the arc length of the second arc block 503, the arc length of the second arc block 503 is greater than the arc length of the first arc block 502, and the first arc bar 501 is on the upper side with a non-notch design, which can prevent the material from contacting the magnet rotor 20, while the first drainage port 504 arranged below can drain the liquid, thereby improving the drainage effect.

[0045] Example 2

[0046] Reference Figure 7, this embodiment is different from Embodiment 1 in that: the positioning unit 50 includes a second arc strip 505 and a third arc block 507. There are two second arc strips 505, which are respectively distributed on both sides of the third arc block 507 to form a semi-circular structure. The third arc block 507 is located on the inner bottom surface of the tank body 10;

[0047] The magnetic rotor 20 is placed in the semi-circular structure;

[0048] It further includes a second liquid discharge port 506. The gap between the second arc strip 505 and the third arc block 507 is the second liquid discharge port 506.

[0049] The positioning unit 50 in this embodiment is designed as a semi-circular structure, reducing the number of welding points. The semi-circular structure serves as a supporting object for the magnetic rotor 20 to prevent the magnetic rotor 20 from moving downward due to its own gravity when it is inclined. The second liquid discharge port 506 provided in the semi-circular structure can also prevent material accumulation, improving practicality.

[0050] In one specific embodiment, the arc length L4 of the second arc strip 505 is greater than the arc width L3 of the second liquid discharge port 506. The second arc strip 505 serves as the main supporting object with a longer arc length, a larger bearing area, and better load-bearing capacity.

[0051] In Embodiment 1 and Embodiment 2, the first arc strip 501, the first arc block 502, the second arc block 503, the second arc strip 505, and the third arc block 507 are all fixed to the inner wall of the tank body 10 by welding. There is no gap between the inner wall of the tank body 10 and the positioning unit 50, and there are no problems such as detachment.

[0052] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
