Description

Technical Field

[0001] The invention relates to the technical field of stirring equipment, and in particular to a slurry stirring device for processing glutinous rice flour. Background Art

[0002] Glutinous rice flour is a powdered product made from glutinous rice as the main ingredient. It can be used to make foods such as glutinous rice balls, Yuanxiao, and glutinous rice cakes. The production process of glutinous rice flour includes the following steps: washing, slightly ripening, soaking, fermenting, drying, and crushing the glutinous rice. Among them, fermentation is to add a fermentation agent and white sugar to the soaked material and stir to obtain a mixture. Stirring is conducive to uniform temperature and nutrient concentration during the fermentation process, promotes the transfer and dissolution of oxygen, and thus helps to improve fermentation efficiency and product quality stability.

[0003] However, due to the high viscosity of glutinous rice flour, when the glutinous rice slurry is stirred, the glutinous rice is easy to adhere to the cylinder wall, and it is not easy to discharge the material. For example, the patent document with the announcement number CN116966808B discloses a stirring device for acetic acid fermentation, which comprises a stirring tank body, a rotating frame rotatably arranged in the stirring tank body, a first stirring shaft and a second stirring shaft are arranged on both sides of the rotating frame, the first stirring shaft is provided with a first stirring blade that fits with the bottom of the inner wall of the stirring tank body, and the second stirring shaft is provided with a second stirring blade that fits with the side wall of the stirring tank body.

[0004] In the above stirring device, the rotation of the rotating frame drives the first stirring blade and the second stirring blade to rotate, thereby scraping off the materials on the bottom and side walls of the inner wall of the stirring tank. However, when the stirring device stirs the glutinous rice slurry, the sticky glutinous rice will not only adhere to the bottom and side walls of the inner wall of the tank, but also adhere to the stirring frame during the continuous contact between the stirring frame and the glutinous rice. In addition, the glutinous rice will contact and squeeze each other, and will also clump during stirring, making it difficult to disperse, resulting in uneven stirring of the glutinous rice and the starter, thereby affecting the fermentation quality. Summary of the invention

[0005] In view of this, the present invention provides a slurry stirring device for processing glutinous rice flour, which solves the technical problem in the prior art that glutinous rice is easy to agglomerate and adhere to a stirring frame during the fermentation and stirring process of glutinous rice slurry.

[0006] In order to solve the above technical problems, the present invention provides a slurry stirring device for processing glutinous rice flour, comprising a stirring frame 1 and a stirring frame 2 which are rotatably arranged in a tank body, and a driving mechanism which drives the stirring frame 1 and the stirring frame 2 to rotate synchronously; Two stirring racks are provided and are respectively located on both sides of the stirring rack one. The stirring rack one and the stirring rack two rotate in opposite directions. The stirring rack one has a stirring rod one, and the stirring rack two has a stirring rod two. The stirring rod one and the stirring rod two are arranged alternately. The stirring frames 1 and 2 are both slidably connected with scrapers that abut against the inner wall of the tank body, and scrapers are elastically connected above the scrapers and on both sides of the stirring frame 1, and the two scrapers are provided with semicircular scraping holes on the opposite sides that can abut against the outer surfaces of the stirring rods 1 and 2; ratchet pawls and ratchet wheels that can stop the rotation of the stirring frames 1 and 2 and are coplanar are provided in the tank body; when the stirring frames 1 and 2 are coplanar, the driving mechanism drives the scrapers to rise and fall.

[0007] By adopting the above technical solution, the stirring rods 1 and 2 are arranged alternately and rotate in opposite directions, which can break up the glutinous rice in the tank, solving the technical problem that the glutinous rice is easy to clump during the fermentation and stirring of the glutinous rice slurry. The scraper plate drives the scraper plate to slide up and down along the stirring frame 1 and the stirring frame 2, and the scraper plate can scrape off the glutinous rice adhering to the inner wall of the tank. The semicircular scraping holes on the two scrapers can scrape off the glutinous rice adhering to the stirring rods 1 and 2, solving the technical problem that the glutinous rice is difficult to discharge during the subsequent discharge, resulting in waste of glutinous rice slurry.

[0008] Preferably, the lower end of stirring rod one is fixedly mounted on cross bar one, the upper end of stirring rod two is fixedly mounted on cross bar two, cross bar one is fixedly connected to rotating shaft one, cross bar two is fixedly connected to rotating shaft two, and the driving mechanism drives rotating shaft one and rotating shaft two to rotate synchronously to realize synchronous rotation of stirring frame one and stirring frame two.

[0009] By adopting the above technical solution, the positions of cross bar 1 and cross bar 2 are different to prevent the interference between stirring rack 1 and stirring rack 2 caused by different rotation directions. In the initial position, stirring rack 1 and stirring rack 2 are coplanar. When stirring rack 1 and stirring rack 2 rotate the same number of circles, they can still remain coplanar, so that stirring rack 1 and stirring rack 2 can pass through the scraper, so that the semicircular scraping holes on the scraper can scrape the glutinous rice off stirring rod 1 and stirring rod 2.

[0010] Preferably, the driving mechanism includes a driving motor arranged above the tank body, a stirring frame transmission assembly driven by the driving motor, a scraper transmission assembly driven by the driving motor, and a friction assembly capable of controlling the stirring frame transmission assembly to stop rotating.

[0011] By adopting the above technical solution, the driving motor can drive the stirring frame transmission assembly and the scraper transmission assembly to rotate, thereby reducing the number of power sources used and saving costs.

[0012] Preferably, the scraper transmission assembly includes a driving gear fixedly mounted on the output shaft of the driving motor, a transmission tube rotatably connected to a rotating shaft, a transmission tube gear fixedly mounted on the transmission tube and meshing with the driving gear, a spiral blade is installed on the transmission tube, a cover plate is detachably connected above the scraper, a transmission member is fixedly connected to the cover plate, and a threaded groove matching the spiral blade is opened in the transmission member.

[0013] By adopting the above technical solution, the driving gear drives the transmission tube gear to rotate, and then drives the transmission tube to rotate. The spiral sheet on the transmission tube matches the spiral groove, so that the transmission member moves up and down, and then the cover plate and the scraper plate move up and down. The scraper plate drives the scraper plate to move up and down to scrape the glutinous rice off the inner wall of the tank, stirring rod one and stirring rod two.

[0014] Preferably, the stirring frame transmission assembly includes a one-way gear rotatably connected to the output shaft of the driving motor, a rotating shaft gear 1 fixedly mounted on the rotating shaft 1 and meshing with the one-way gear, and a rotating shaft gear 2 fixedly mounted on the rotating shaft 2 and externally meshing with the rotating shaft gear 1.

[0015] By adopting the above technical solution, the one-way gear and the rotating shaft gear 1 and the rotating shaft gear 2 are meshed in sequence, which can drive the stirring frame 1 and the stirring frame 2 to rotate synchronously. Since the rotating shaft gear 1 and the rotating shaft gear 2 are externally meshed, the rotation directions of the stirring frame 1 and the stirring frame 2 are opposite, which makes it easier for the stirring rod 1 and the stirring rod 2 to break up the clumped glutinous rice.

[0016] Preferably, the friction assembly includes a gland slidably connected above the one-way gear, and a friction plate elastically arranged in the gland and slidably connected to the output shaft of the driving motor; the friction plate and the one-way gear are connected by friction transmission, and an adjusting bolt that can push the gland downward is provided on one side of the tank body; The pawl is rotatably connected under the rotating shaft gear one, the ratchet is fixedly installed on the rotating shaft one, and the ratchet is provided with ratchet teeth. When the ratchet teeth abut against the pawl, the stirring frame one and the stirring frame two are coplanar, and the pawl cooperates with the ratchet wheel to make the rotating shaft one rotate in one direction.

[0017] By adopting the above technical solution, when the stirring frame 1 and the stirring frame 2 stir the glutinous rice slurry, the output shaft of the driving motor drives the friction plate to rotate clockwise. Under the action of friction, the friction plate drives the one-way gear to rotate clockwise, and then drives the rotating shaft gear 1 to rotate counterclockwise, and the rotating shaft gear 2 to rotate clockwise, so that the stirring frame 1 and the stirring frame 2 rotate in opposite directions. After the stirring is completed, the output shaft of the driving motor drives the friction plate to rotate counterclockwise, the friction plate drives the one-way gear to rotate counterclockwise, and the one-way gear drives the rotating shaft gear 1 to rotate clockwise. Due to the action of the ratchet and the ratchet, the rotating shaft 1 is locked, the rotating shaft gear 1 stops rotating, the one-way gear and the rotating shaft gear 2 also stop rotating, the stirring frame 1 and the stirring frame 2 stop stirring and are coplanar, the output shaft of the driving motor drives the driving gear to rotate counterclockwise, and the driving gear drives the transmission tube gear to rotate clockwise, so that the scraper and the scraper located on the upper part of the tank body move downward to scrape off the glutinous rice on the inner wall of the tank body, the stirring rod 1 and the stirring rod 2. The magnitude of the friction between the friction plate and the one-way gear can be adjusted by adjusting the bolt.

[0018] Preferably, the scraper is provided with a plurality of slide grooves, one end of the slide groove is fixedly connected with a connecting column 1, the scraper is fixedly connected with a plurality of connecting columns 2 that can slide in the slide grooves, and a reset spring is connected between the connecting column 1 and the connecting column 2.

[0019] By adopting the above technical solution, when the scraper plate and the scraper plate move down and contact the cross bar 2, the cross bar 2 pushes the two scrapers away from each other, and the reset spring is compressed, which is conducive to the cross bar 2 passing through the middle of the two scrapers. After the cross bar 2 passes through the scraper plate, the two scrapers approach each other under the action of the elastic force of the reset spring, so that the semicircular scraping holes on the two scrapers can abut against the outer surfaces of the stirring rod 1 and the stirring rod 2, so as to facilitate scraping off the glutinous rice on the stirring rod 1 and the stirring rod 2.

[0020] Preferably, the middle parts of the cover plate and the scraper are provided with strip holes through which the two cross bars can pass, the scraper is located between the scraper and the cover plate, and the upper and lower end surfaces of the two scrapers facing each other are provided with chamfers.

[0021] By adopting the above technical solution, when the scraper moves up and down, the chamfer makes it easier for the second cross bar to push the two scrapers away from each other, which is conducive to the second cross bar passing through the middle of the two scrapers.

[0022] The beneficial effects of the above technical solution of the present invention are as follows: 1. The stirring rods 1 and 2 of the present invention are arranged alternately and rotate in opposite directions. When the stirring rods 1 and 2 are coplanar, the glutinous rice agglomerated in the tank can be broken up, which is beneficial to uniformly stirring the glutinous rice and the leavening agent and improving the fermentation quality. At the same time, the scraper plate and the scraper can move downward and scrape off the glutinous rice adhered to the inner wall of the tank, the stirring rods 1 and 2, which is beneficial to the discharge of this part of the glutinous rice and reduces the waste of glutinous rice slurry.

[0023] 2. The driving motor of the present invention can drive the stirring frame 1, the stirring frame 2 and the scraper to rotate, thereby reducing the number of power sources used and saving costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] like Figure 2 and Figure 5 As shown, the stirring frame 3 includes a cross bar 31 , a stirring rod 32 and a rotating shaft 33 .

[0032] like Figure 2 and Figure 5 As shown, the axes of the second rotating shaft 33, the second stirring rod 32 and the first stirring rod 22 are parallel, a plurality of second stirring rods 32 are provided, the second rotating shaft 33 is located in the middle of the plurality of second stirring rods 32, the second rotating shaft 33 and the upper parts of the second stirring rod 32 are fixedly mounted on the second crossbar 31, and the second crossbar 31 is parallel to the first crossbar 21. The driving mechanism 5 drives the second rotating shaft 33 to rotate, so as to drive the second stirring frame 3 to rotate.

[0033] like Figure 2 and Figure 5 As shown, two stirring racks 2 3 are provided, which are respectively located on both sides of the stirring rack 1 2. The stirring racks 1 2 and 2 3 rotate in opposite directions. The stirring rods 1 22 and 2 32 are staggered at intervals, which can break up the clumped glutinous rice in the tank body 1, which is beneficial to evenly stir the glutinous rice and the leavening agent and improve the fermentation quality.

[0034] like Figure 2 and Figure 3 As shown, the stirring rack 1 2 and the stirring rack 2 3 are both slidably connected with a scraper 4 that abuts against the inner wall of the tank body 1, and a strip hole 41 is provided in the middle of the scraper 4 for the cross bar 2 31 to pass through. Scrapers 42 are provided above the scraper 4 and on both sides of the strip hole 41, and the two scrapers 42 are provided with semicircular scraping holes 425 that can abut against the outer surfaces of the stirring rod 1 22 and the stirring rod 2 32 on the opposite sides. Figure 4 As shown, two semicircular scraping holes 425 are abutted to form a circular hole, and the stirring rod 1 22 and the stirring rod 2 32 can pass through the circular hole. As the scraper 42 moves downward, the circular hole can scrape the glutinous rice on the stirring rod 1 22 and the stirring rod 2 32.

[0035] like Figure 2 and Figure 3 As shown, the driving mechanism 5 drives the scraper 4 to rise and fall, and drives the scraper 42 to rise and fall. The scraper 4 can scrape off the glutinous rice adhering to the inner wall of the tank body 1, and the semicircular scraping hole 425 can scrape off the glutinous rice adhering to the stirring rod 1 22 and the stirring rod 2 32, which is beneficial to the discharge of this part of the glutinous rice and reduces the waste of glutinous rice slurry.

[0036] like Figure 4 As shown, the connection method between the scraper 4 and the scraper plate 42 is: a plurality of slide grooves 421 are opened on the scraper plate 42, one end of the slide groove 421 is fixedly connected to a connecting column 1 422, a plurality of connecting columns 2 423 that can slide in the slide groove 421 are fixedly connected to the scraper 4, a return spring 424 is connected between the connecting column 1 422 and the connecting column 2 423, and chamfers are provided on the upper end surface and the lower end surface of the side facing each other of the two scrapers 42.

[0037] like Figure 3 and Figure 4 As shown, when the scraper plate 4 and the scraper plate 42 move downward and contact the cross bar 2 31, the cross bar 2 31 pushes the two scrapers 42 away from each other, and the return spring 424 is compressed, which is conducive to the cross bar 2 31 passing through the middle of the two scrapers 42. After the cross bar 2 31 passes through the scrapers 42, the two scrapers 42 approach each other under the elastic force of the return spring 424, so that the semicircular scraping holes 425 on the two scrapers 42 can abut against the outer surfaces of the stirring rod 1 22 and the stirring rod 2 32, which is convenient for scraping off the glutinous rice on the stirring rod 1 22 and the stirring rod 2 32. In the process of the scraper plate 42 moving up and down, the chamfering makes it easier for the cross bar 2 31 to push the two scrapers 42 away from each other, which is conducive to the cross bar 2 31 passing through the middle of the two scrapers 42.

[0038] like Figure 2 As shown, the driving mechanism 5 includes a driving motor 51 , a scraper transmission assembly 52 , a stirring frame transmission assembly 53 and a friction assembly 54 .

[0039] like Figure 2 As shown, the driving motor 51 is arranged above the tank body 1 to provide power for the stirring frame transmission assembly 53 and the scraper transmission assembly 52.

[0040] like Figure 2 As shown, the scraper transmission assembly 52 includes a driving gear 521 , a transmission tube 522 and a transmission tube gear 523 .

[0041] like Figure 2 and Figure 8 As shown, the driving gear 521 is fixedly mounted on the output shaft 511 of the driving motor 51, the transmission tube 522 is rotatably connected to the rotating shaft 23, the transmission tube gear 523 is fixedly mounted on the transmission tube 522, and the driving gear 521 and the transmission tube gear 523 are externally meshed.

[0042] like Figure 5 and Figure 6As shown, a spiral piece 524 is installed on the transmission tube 522, and a cover plate 43 is detachably connected to the top of the scraper 4, and the detachable connection is a bolt connection. A strip hole 41 is also provided in the middle of the cover plate 43 for the cross bar 31 to pass through, and the scraper 42 is located between the scraper 4 and the cover plate 43. A transmission member 431 is fixedly connected to the cover plate 43, and the transmission member 431 is a columnar structure, and a thread groove matching the spiral piece 524 is provided in the transmission member 431.

[0043] like Figure 5 and Figure 6 As shown, the driving gear 521 drives the transmission tube gear 523 to rotate, and then drives the transmission tube 522 to rotate. The spiral piece 524 on the transmission tube 522 can turn the glutinous rice slurry. Since the spiral piece 524 matches the spiral groove, the rotation of the spiral piece 524 can drive the transmission member 431 to move up and down, and then the cover plate 43 and the scraper plate 4 move up and down. The scraper plate 4 drives the scraper plate 42 to move up and down to scrape the glutinous rice on the inner wall of the tank body 1, the stirring rod 1 22 and the stirring rod 2 32.

[0044] like Figure 2 As shown, the stirring frame transmission assembly 53 includes a one-way gear 531, a rotating shaft gear 1 532 and a rotating shaft gear 2 533.

[0045] like Figure 2 and Figure 6 As shown, the one-way gear 531 is rotatably connected to the output shaft 511 of the driving motor 51 and is located above the driving gear 521. The rotatable connection is a bearing connection. The output shaft 511 of the driving motor 51 drives the one-way gear 531 to rotate by the friction force of the friction assembly 54. The rotating shaft gear 1 532 is fixedly mounted on the rotating shaft 1 23, and the rotating shaft gear 2 533 is fixedly mounted on the rotating shaft 2 33. The one-way gear 531, the rotating shaft gear 1 532 and the rotating shaft gear 2 533 are externally meshed in sequence. The rotating shaft gear 1 532 and the rotating shaft gear 2 533 are located above the transmission tube gear 523.

[0046] like Figure 2 and Figure 6 As shown, the one-way gear 531 and the shaft gear 1 532 and the shaft gear 2 533 are meshed in sequence, which can drive the shaft 1 23 and the shaft 2 33 to rotate synchronously, and then drive the stirring frame 1 2 and the stirring frame 2 3 to rotate synchronously. Since the shaft gear 1 532 and the shaft gear 2 533 are externally meshed, the stirring frame 1 2 and the stirring frame 2 3 rotate in opposite directions, which makes it easier for the stirring rod 1 22 and the stirring rod 2 32 to break up the clumped glutinous rice.

[0047] like Figure 2 The friction assembly 54 shown includes the following: Figure 8 The pressure cover 541, the friction plate 542, Figure 6 Pawl 543 and ratchet 544 are shown.

[0048] like Figure 7 and Figure 8 As shown, the pressure cover 541 is sleeved on the output shaft 511 of the driving motor 51 with a gap between the pressure cover 541 and the output shaft 511, the pressure cover 541 is slidably connected above the one-way gear 531, the friction plate 542 is sleeved on the output shaft 511 of the driving motor 51 and is key-connected to the output shaft 511, the friction plate 542 is located in the pressure cover 541 and a columnar spring 546 is connected between the pressure cover 541 and the columnar spring 546 is sleeved on the output shaft 511. The friction plate 542 abuts against the one-way gear 531, and the two are connected through friction transmission.

[0049] like Figure 7 and Figure 8 As shown, one side of the tank body 1 is provided with an adjusting bolt 547 which can push the pressure cover 541 to move downward, and the end of the adjusting bolt 547 and the pressure cover 541 are provided with mutually matching inclined surfaces. When the adjusting bolt 547 is tightened, the adjusting bolt 547 moves toward the side close to the pressure cover 541 and pushes the pressure cover 541 to move downward, and the columnar spring 546 compresses and presses the friction plate 542 downward, thereby reducing the distance between the friction plate 542 and the one-way gear 531 and increasing the friction between the two. Conversely, when the adjusting bolt 547 is loosened, the friction between the friction plate 542 and the one-way gear 531 is reduced.

[0050] like Figure 5 and Figure 6 As shown, a crossbeam 548 is provided above the interior of the tank 1, and the rotating shaft 1 23 and the rotating shaft 2 33 are both rotatably connected to the crossbeam 548. A ratchet 543 is rotatably connected to the portion of the crossbeam 548 near the rotating shaft 1 23, and the ratchet 543 is located below the rotating shaft gear 1 532. A ratchet 544 is fixedly installed on the rotating shaft 1 23, and a ratchet 545 is installed on the ratchet 544. When the ratchet 545 abuts against the ratchet 543, the stirring frame 1 2 and the stirring frame 2 3 are coplanar, and the ratchet 543 cooperates with the ratchet 544 to enable the rotating shaft 1 23 to rotate in one direction. The structure of the ratchet 543 and the ratchet 544 is shown in FIG. Fig. 9 shown.

[0051] like Figure 5 and Figure 6 As shown, when the stirring rack 1 2 and the stirring rack 2 3 stir the glutinous rice slurry, the output shaft 511 of the driving motor 51 drives the friction plate 542 to rotate clockwise. Under the action of the friction force, the friction plate 542 drives the one-way gear 531 to rotate clockwise, and then drives the rotating shaft gear 1 532 to rotate counterclockwise, and the rotating shaft gear 2 533 to rotate clockwise, so that the stirring rack 1 2 and the stirring rack 2 3 rotate in opposite directions.

[0052] like Figure 7 and Figure 8As shown in FIG. 1 , after the stirring is finished, the output shaft 511 of the driving motor 51 drives the friction plate 542 to rotate counterclockwise, and the friction plate 542 drives the one-way gear 531 to rotate counterclockwise, as shown in FIG. Figure 5 and Figure 6 As shown, the one-way gear 531 drives the shaft gear 1 532 to rotate clockwise, and the shaft 1 23 drives the ratchet 544 to rotate until the ratchet 545 abuts against the pawl 543, so that the shaft 1 23 is locked, the shaft gear 1 532 stops rotating, the one-way gear 531 and the shaft gear 2 533 also stop rotating, the stirring frame 1 2 and the stirring frame 2 3 stop stirring and are coplanar, the output shaft 511 of the driving motor 51 drives the driving gear 521 to rotate counterclockwise, and the driving gear 521 drives the transmission tube gear 523 to rotate clockwise, so that the scraper 4 and the scraper 42 located on the upper part of the tank body 1 move downward, and the glutinous rice on the inner wall of the tank body 1, the stirring rod 1 22 and the stirring rod 2 32 are scraped off.

[0053] The implementation principle of a slurry stirring device for glutinous rice flour processing in this embodiment: In the initial position, the scraper 4 and the scraper plate 42 are located above the rotating shaft 23 where the spiral sheet 524 is not provided. When the stirring frame 1 2 and the stirring frame 2 3 stir the glutinous rice slurry, the output shaft 511 of the driving motor 51 drives the friction plate 542 to rotate clockwise. Under the action of the friction force, the friction plate 542 drives the one-way gear 531 to rotate clockwise, thereby driving the rotating shaft gear 1 532 to rotate counterclockwise, and the rotating shaft gear 2 533 rotates clockwise, so that the stirring frame 1 2 and the stirring frame 2 3 rotate in opposite directions. The stirring rods 1 22 and the stirring rods 2 32 are arranged alternately at intervals, which can break up the glutinous rice agglomerated in the tank body 1, which is conducive to uniform mixing of the glutinous rice and the leavening agent, thereby improving the fermentation quality. The output shaft 511 of the driving motor 51 drives the driving gear 521 to rotate clockwise, and the driving gear 521 drives the transmission tube gear 523 to rotate counterclockwise, and the transmission tube 522 and the spiral piece 524 rotate counterclockwise to turn the glutinous rice slurry. Since the scraper 4 and the scraper plate 42 are located above the rotating shaft 23 where the spiral piece 524 is not provided, the spiral piece 524 cannot drive the transmission member 431 on the cover plate 43 to rise, so that the scraper 4 and the scraper plate 42 do not rise either. After the stirring is finished, the output shaft 511 of the driving motor 51 drives the friction plate 542 to rotate counterclockwise, the friction plate 542 drives the one-way gear 531 to rotate counterclockwise, the one-way gear 531 drives the shaft gear 1 532 to rotate clockwise, the shaft 1 23 drives the ratchet 544 to rotate until the ratchet tooth 545 abuts against the pawl 543, so that the shaft 1 23 is locked, the shaft gear 1 532 stops rotating, the one-way gear 531 and the shaft gear 2 533 also stop rotating, and the stirring frame 1 2 and the stirring frame 2 are turned to the same direction. 23 stop stirring and are coplanar, the output shaft 511 of the driving motor 51 drives the driving gear 521 to rotate counterclockwise, the driving gear 521 drives the transmission tube gear 523 to rotate clockwise, the transmission tube 522 and the spiral piece 524 rotate clockwise, the spiral piece 524 cooperates with the threaded groove in the transmission member 431, drives the transmission member 431 and the cover plate 43 to move downward, and then drives the scraper 4 and the scraper 42 to move downward, and scrapes the glutinous rice on the inner wall of the tank body 1, the stirring rod 1 22 and the stirring rod 2 32.
