Description

Technical Field

[0001] The invention belongs to the field of stirring and mixing equipment, and in particular relates to a raw material stirring and mixing device and a mixing method for shrimp feed production. Background Art

[0002] A mixer is a mechanical device that uses mechanical force and gravity to evenly mix two or more materials. During the mixing process, it can also increase the contact surface area of ​​the materials to promote chemical reactions and accelerate physical changes. Commonly used mixers are divided into four categories: gas and low-viscosity liquid mixers, medium- and high-viscosity liquid and paste mixers, and powdered and granular solid material mixers.

[0003] When mixing feed, solid raw materials need to be wet mixed and stirred. At this time, the solid raw materials are more viscous, which makes it easy for the raw materials to stick together, thereby increasing the difficulty of mixing the raw materials. When unloading, the raw materials are also easy to adhere to the inner wall of the mixer, so that some raw materials will remain in the mixer, affecting the subsequent use of the mixer.

The reciprocating swing assembly can drive the sealing plate 51 to rotate and open, and drive the opened sealing plate 51 to reciprocate; the inner wall cleaning assembly is tightly installed on the inner wall of the mixing box 1 and is transmission-connected with the sealing plate 51, so that when the sealing plate 51 reciprocates, it can drive the inner wall cleaning assembly to reciprocate up and down along the inner wall of the mixing box 1 to scrape and clean the inner wall of the mixing box 1;

[0045] Specifically, during the raw material mixing process, firstly, the raw materials, the water required for mixing and the additives are transported to the mixing chamber inside the mixing box 1 through the feeding funnel 3, and then the raw materials in the mixing box 1 are thrown upwards and stirred by the stirring component, so that the raw materials are gradually mixed evenly, and at the same time, the stirring component drives the breaking component to hit and disperse the raw materials thrown upwards, so as to improve the mixing effect; when the mixing is completed, the sealing plate 51 is driven to rotate and open by the reciprocating swing component, so that the mixed material in the mixing chamber automatically falls and discharges, and when the preliminary discharge is completed, the sealing plate 51 is driven to swing back and forth by the reciprocating swing component to swing the mixed material adhering to the sealing plate 51 off, and at the same time, the sealing plate 51 drives the inner wall cleaning component to reciprocate up and down along the inner wall of the mixing box 1, scrapes and cleans the inner wall of the mixing box 1, and removes the mixed material adhering to the inner wall of the mixing box 1;

[0047] Example 2

[0048] See also Figure 2 , Figure 5 As shown, the difference between this embodiment and the above embodiment is that the stirring assembly includes a stirring shaft 41 and a stirring motor 44, the stirring shaft 41 is rotatably installed in the mixing chamber inside the mixing box 1, and the outer ring of the stirring shaft 41 is fixedly installed with multiple groups of copying plates 42, the stirring motor 44 is fixedly installed on the outer wall of the mixing box 1, and the output end of the stirring motor 44 is drivingly connected to one end of the stirring shaft 41;

[0049] When the stirring assembly is working, the stirring motor 44 drives the stirring shaft 41 to rotate. When the stirring shaft 41 rotates, it drives the lifting plate 42 to make a circular motion in the mixing box 1. During the circular motion, the lifting plate 42 disturbs and stirs the raw materials in the mixing box 1, and transports and drops the raw materials upward to improve the stirring and mixing effect of the raw materials.

[0050] Example 3

[0051] See also Figure 5 , Figure 6 , Fig. 9 As shown, the difference between this embodiment and the above embodiment is that the disintegrating assembly includes a transmission shaft 45, a plurality of transmission rods 49 and a plurality of rotating shafts 410. The transmission shaft 45 is rotatably mounted on the upper end of the mixing box 1, one end of the transmission shaft 45 is transmission-connected to the stirring shaft 41, and a plurality of transmission bevel gears 46 are fixedly mounted on the transmission shaft 45; the plurality of transmission rods 49 are rotatably mounted on the top surface of the mixing box 1, and correspond one-to-one with the plurality of transmission bevel gears 46, and the bottom end of the transmission rod 49 is fixedly mounted with a driven bevel gear 410 meshing with the corresponding transmission bevel gear 46. 7. A transmission gear 48 is fixedly installed on the upper end of the transmission rod 49; multiple rotating shafts 410 are rotatably installed at the top of the mixing box 1 and correspond to the multiple transmission rods 49 one by one. A driven gear 411 meshing and transmission-connected with the corresponding transmission gear 48 is fixedly installed on the upper end of the rotating shaft 410, and a dispersing impeller 43 is fixedly installed on the bottom end of the rotating shaft 410; a transmission wheel 412 is fixedly installed on one end of the stirring shaft 41, and a driven wheel 414 is fixedly installed on one end of the transmission shaft 45, and the transmission wheel 412 and the driven wheel 414 are connected through a transmission belt 413;

[0052] When the stirring shaft 41 rotates, the transmission shaft 45 is driven to rotate synchronously through the cooperation of the transmission wheel 412, the transmission belt 413 and the driven wheel 414. Then, the transmission shaft 45 drives multiple transmission rods 49 to rotate synchronously through the meshing transmission of the transmission bevel gear 46 and the driven bevel gear 47. When the transmission rod 49 rotates, the meshing transmission between the transmission gear 48 and the driven gear 411 drives the corresponding rotating shaft 410 to rotate, and then the rotating shaft 410 drives the breaking impeller 43 to rotate. The breaking impeller 43 breaks up the raw materials thrown upward by the shovel 42, so that the raw materials are dispersed more evenly, thereby improving the stirring and mixing effect of the raw materials.

[0053] Example 4

[0054] See also Figure 2 , Figure 3 , Fig. 9 , Fig.10 As shown, the difference between this embodiment and the above embodiment is that two sealing plates 51 are provided, and the outer ends of the two sealing plates 51 are fixedly installed with pins 59, and the two sealing plates 51 are rotatably installed on both sides of the interior of the mixing box 1 through the pins 59, and the lower end of the mixing box is provided with a discharge funnel 52 located below the sealing plates 51; the reciprocating swing assembly includes a support shaft 53 and a transfer shaft 58, the support shaft 53 is rotatably installed inside the mixing box 1 and is located below the sealing plate 51, the transfer shaft 58 is fixedly installed on the bottom surface of the sealing plate 51, and a plurality of equidistantly distributed eccentric shafts 56 are fixedly installed on the support shaft 53, and the eccentric shaft 56 is rotatably installed on the eccentric shaft 56. A support rod 57 is rotatably installed on the mixing box 1, and the other end of the support rod 57 is rotatably connected to the adapter shaft 58; the reciprocating swing assembly also includes a discharge motor 514, a synchronous shaft 518, a synchronous wheel 519 and a synchronous gear 521. The discharge motor 514 is fixedly installed on the outer wall of the mixing box 1 and is transmission-connected to one of the support shafts 53, and a synchronous shaft 518 is rotatably installed on one side of the support shaft 53. The synchronous shaft 518 and the support shaft 53 are fixedly installed with mutually meshing synchronous gears 521. The synchronous shaft 518 and the other support shaft 53 are both fixedly installed with synchronous wheels 519, and the two synchronous wheels 519 are transmission-connected through a synchronous belt 520;

[0055] Among them, the support rod 57 is initially in a straight line with the connecting plate between the eccentric shaft 56 and the support shaft 53. At this time, the support rod 57 pushes the adapter shaft 58 to the highest position, so that the sealing plate 51 is abutted and sealed in the drop port of the mixing chamber through the adapter shaft 58. When the stirring and mixing is completed and unloading is required, the support shaft 53 connected thereto is driven to rotate by the unloading motor 514. At the same time, the support shaft 53 drives the synchronous shaft 518 to rotate in the opposite direction to the support shaft 53 through the meshing transmission of the synchronous gear 521. After that, the synchronous shaft 518 drives another support shaft 53 to rotate synchronously through the coordinated transmission of the synchronous wheel 519 and the synchronous belt 520, thereby The transmission causes the two support shafts 53 to rotate in opposite directions at the same speed, and then the two support shafts 53 pull the two sealing plates 51 to the sides respectively through the eccentric shaft 56 and the support rod 57 to open, thereby opening the discharge port, so that the mixed material is transported downward through the discharge port to the discharge funnel 52 below, and during the unloading process, the discharge motor 514 is in a shutdown state so that the discharge port is always in an open state; and when the initial unloading of the mixed material is completed, the discharge motor 514 is turned on again to drive the two support shafts 53 to rotate again, so that the support shafts 53 cooperate with the eccentric shaft 56 and the support rod 57 to drive the sealing plate 51 to swing back and forth, thereby the mixed material adhering to the sealing plate 51 is thrown off by the reciprocating swing and the mechanical vibration generated during the swinging process.

[0056] Furthermore, the support rod 57 is a hydraulic telescopic rod. When the sealing plate 51 is driven to swing back and forth, the hydraulic telescopic rod is driven to contract to shorten the length of the support rod 57. At this time, even if the adapter shaft 58 is pushed to the highest position, the sealing plate 51 is still in a tilted open state, so that the drop port of the mixing chamber is always in an open state when the sealing plate 51 swings back and forth, which facilitates the mixed material to continue to drop downward.

[0057] Example 5

[0058] See also Figure 2 , Figure 4 , Figure 7 , Figure 8 As shown, the difference between this embodiment and the above embodiment is that the inner wall cleaning assembly includes a lifting rod 54, a plurality of scraping strips 55 and a telescopic connecting piece, the lifting rod 54 is slidably installed on the inner wall of the mixing box 1, and a plurality of equidistantly distributed lifting seats 513 are fixedly installed on the lifting rod 54, and a plurality of scraping strips 55 are equidistantly distributed and slide closely on the inner wall of the mixing box 1, and the ends of the scraping strips 55 are fixedly connected to the corresponding lifting seats 513 through the telescopic connecting piece; an eccentric wheel 510 is fixedly installed on the end of the pin shaft 59, an eccentric rod 511 is fixedly installed on the outer ring of the eccentric wheel 510, a connecting rod 512 is rotatably installed on the eccentric rod 511, and one end of the connecting rod 512 is rotatably connected to the bottom end of the lifting rod 54;

[0059] When the sealing plate 51 swings back and forth, it drives the pin shaft 59 and the eccentric wheel 510 to rotate back and forth. When the eccentric wheel 510 rotates, it can drive the lifting rod 54 to move back and forth through the eccentric rod 511 and the connecting rod 512, so that the lifting rod 54 drives the scraper 55 to move back and forth along the inner wall of the mixing box 1 through the lifting seat 513 and the telescopic connecting piece, so that the scraper 55 scrapes and cleans the inside of the mixing box 1, removes the mixed material adhered to the inner wall of the mixing box 1, and keeps the inner wall of the mixing box 1 clean.

[0060] Furthermore, the telescopic connection member includes a fixed sleeve 515 and a telescopic shaft 517. The fixed sleeve 515 is fixedly installed on the inner side of the lifting seat 513. One end of the telescopic shaft 517 is slidably inserted into the fixed sleeve 515, and the other end is rotatably connected to the scraper 55. A pressure spring 516 is installed inside the fixed sleeve 515 to abut against the end of the telescopic shaft 517.

[0061] Among them, the inner walls on both sides of the mixing box 1 are both arc-shaped structures, and the scraper 55 is elastically abutted against the arc-shaped inner wall through the elastic force of the pressure spring 516. When the scraper 55 moves up and down along the arc-shaped inner wall for scraping and cleaning, the telescopic shaft 517 can reciprocate and retract under the abutment of the arc-shaped inner wall and the reset force of the pressure spring 516, so that the scraper 55 is always in abutment against the arc-shaped inner wall, ensuring the scraping and cleaning effect of the scraper 55 on the inner wall of the mixing box 1.

At the same time, the stirring component drives the breaking component to hit and disperse the raw materials thrown upward to improve the stirring and mixing effect;

[0065] When stirring and mixing is completed, the sealing plate 51 is driven to rotate and open by the reciprocating swinging assembly, so that the mixture in the mixing chamber automatically falls down and is discharged. When the discharge is completed, the sealing plate 51 is driven to swing back and forth by the reciprocating swinging assembly to swing the mixture adhering to the sealing plate 51 off. At the same time, the sealing plate 51 drives the inner wall cleaning assembly to reciprocate up and down along the inner wall of the mixing box 1, scrapes and cleans the inner wall of the mixing box 1, and removes the mixture adhering to the inner wall of the mixing box 1.
