Description

Technical Field

[0001] The invention relates to the technical field of drying devices, and in particular to a drying device and a drying process for processing blood powder. Background Art

[0002] In the field of blood powder processing, drying is a crucial link, which is directly related to the quality and market competitiveness of the final product. Traditional blood powder processing drying devices usually use a simple hot air drying method to heat the blood powder with hot air to remove the moisture in it. However, this traditional drying method has many defects, which limits the further improvement of blood powder processing efficiency and product quality.

[0003] Most of the existing blood powder processing and drying devices rely on a hot air circulation system, which generates hot air through a heating element and uses a fan to send the hot air into a drying cylinder to heat and dry the blood powder. This device has a simple structure and is easy to operate, but has the following main problems:

[0004] Low drying efficiency: Due to the uneven distribution of hot air in the drying drum, the blood powder is heated unevenly, some areas of the blood powder are over-dried, while some areas are under-dried, affecting the overall drying efficiency;

[0005] Blood meal agglomeration and adhesion: During the drying process, blood meal is prone to agglomeration or adhesion due to water evaporation, which not only affects the uniform distribution of blood meal, but also may cause blockage in the drying cylinder, increasing maintenance costs;

[0006] Unstable product quality: Due to uneven heating and agglomeration problems during the drying process, the quality of the final product is uneven, affecting the market competitiveness of the product. Summary of the invention

[0011] As a further preferred embodiment of the present technical solution, first bevel gears are rotatably connected on both sides of the fixing frame, a second bevel gear rotatably mounted on the fixing frame is meshedly connected between the two first bevel gears, and one end of the rotating rod is fixedly connected to the second bevel gear.

[0012] As a further preferred embodiment of the present technical solution, a first gear is provided on one side of the first bevel gear, a second gear is meshedly connected to one side of the first gear, and a third gear is meshedly connected to one side of the second gear and fixedly mounted on the positioning shaft.

[0013] As a further preferred embodiment of the present technical solution, a mounting frame is fixedly mounted on the top of the fixing frame, a rotating shaft is rotatably connected to the top of the mounting frame, and one end of the rotating shaft is transmission-connected to the first bevel gear via a synchronous belt pulley transmission member.

[0014] As a further preferred embodiment of the present technical solution, the other end of the rotating shaft is rotatably connected to a rotating rod, the other end of the rotating rod is rotatably connected to a pushing rod, the other end of the pushing rod is rotatably connected to a sliding rod, the other end of the sliding rod is fixedly connected to a control screen, the outer end of the sliding rod is slidably connected to a sleeve rod, and the sleeve rod is fixedly mounted on the mounting frame.

[0015] As a further preferred embodiment of the present technical solution, rollers are arranged on both sides of the top of the support seat, roller rings slidably connected to the rollers are fixedly connected to both sides of the drying cylinder, a driving motor is fixedly installed on the support seat, a driving gear is fixedly connected to the output end of the driving motor, and a driven gear ring meshing with the driving gear is fixedly installed on the outer wall of the drying cylinder.

[0016] The present invention also discloses a drying process of a blood powder processing and drying device, which specifically comprises the following steps:

[0017] Step 1: After the blood meal to be dried is put into the drying cylinder, the servo motor is turned on to drive the positioning shaft to rotate synchronously, the positioning shaft drives the disc to rotate synchronously, the positioning shaft drives the third gear to rotate synchronously when rotating, the disc drives the meshing second gear to rotate synchronously, the second gear drives the meshing first gear to rotate synchronously, so that the first gear drives the first bevel gear to rotate synchronously, so that the first bevel gear drives the meshing second bevel gear to rotate, so that the stirring blade drives the rotating rod, the control rod and the stirring blade to rotate synchronously, so that the stirring blade stirs the blood meal in the discharge cylinder;

[0018] Step 2: The disc rotates synchronously, so that the disc cooperates with the connecting rod and the linkage rod to drive the mounting block, the connecting disc and the control rod to move back and forth, so that the control rod drives the stirring blade located on the connecting shaft to rotate back and forth through the connecting rod, and then the stirring blade breaks up the blood powder to be dried;

[0019] Step three, when the first bevel gear rotates, it drives the rotating shaft to rotate through the synchronous belt pulley transmission member, so that the rotating shaft drives the rotating rod to rotate synchronously, so that the rotating rod drives the pushing rod to move back and forth, so that the pushing rod drives the sliding rod and the control screen to move back and forth, and when the drying cylinder rotates, it drives the blood powder to rotate upward. When the blood powder moves to the position above the control screen, it will naturally fall onto the control screen due to the effect of gravity, so that the blood powder can be dispersed and screened in the process of falling;

[0020] Step 4: Dry the blood powder using a drying drum, and the dried blood powder is discharged through a discharge drum.

[0021] Compared with the prior art, it has the following beneficial effects:

[0022] By starting the servo motor, the positioning shaft and its related transmission components work together to achieve the reciprocating breaking up of the blood meal by the stirring blades. This breaking up not only improves the uniform distribution of the blood meal in the drying drum, but also avoids the phenomenon of blood meal agglomeration or adhesion during the drying process, thereby significantly improving the drying efficiency; the rotation of the positioning shaft not only drives the reciprocating rotation of the stirring blades, but also realizes the synchronous rotation of the stirring blades through the gear transmission system. The combination of this rotation and reciprocating motion enables the blood meal to be fully stirred and mixed in the discharge barrel, ensuring that the blood meal is evenly heated in the subsequent drying process, further improving the drying efficiency and product quality; the rotation of the first bevel gear realizes the reciprocating movement of the control screen through components such as the synchronous pulley transmission parts. This movement is combined with the rotation of the drying drum, so that the blood meal is further dispersed and screened when it falls on the control screen. The sieve hole design of the control screen ensures the uniformity of the blood meal particles, thereby ensuring the consistency of the drying effect, further improving the efficiency of the drying process and the quality of the final product.

[0023] By rotating the stirring blades in the opposite direction to the drying drum, the blood meal is evenly distributed in the drying drum, providing a good material basis for the drying process. This design helps to break the static accumulation of blood meal during the drying process, promotes uniform heating and rapid drying of the blood meal; the reverse rotation of the stirring blades not only promotes the uniform distribution of the blood meal, but also increases the relative movement between the blood meal particles, which helps to quickly evaporate the moisture inside the blood meal; the rotation of the drying drum combined with the reverse rotation of the stirring blades forms a dynamic drying environment, making the drying effect more uniform and efficient.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] Embodiment 1: Combination Figure 1-Figure 8As shown, the present invention provides a technical solution: a drying device for blood powder processing, comprising a support seat 1, a discharge cylinder 2 is arranged on one side of the top of the support seat 1, a drying cylinder 3 is rotatably arranged on one side of the discharge cylinder 2, and a control component 4 is arranged in the drying cylinder 3;

[0035] The control assembly 4 includes a fixed frame 41 fixedly mounted on the outer end of the discharge barrel 2, a rotating rod 42 is rotatably connected to the fixed frame 41, a control rod 43 is arranged inside the rotating rod 42, a mounting groove 418 is provided on the outer wall of the control rod 43, a connecting shaft 419 is fixedly connected to the inner wall of the mounting groove 418, a stirring blade 44 is rotatably connected to the connecting shaft 419, and the inner end of the stirring blade 44 is movably connected to the control rod 43 through a connecting rod. When the rotating rod 42 rotates, it drives the control rod 43 to rotate synchronously, thereby driving the stirring blade 44 to rotate synchronously, so that the stirring blade 44 stirs the raw materials put into the discharge barrel 2 when drying;

[0036] A driving member 45 is provided on the fixing frame 41. The driving member 45 includes a positioning shaft 46 rotatably mounted on both sides of the fixing frame 41. A servo motor 410 is provided on one side of the positioning shaft 46. A disc 47 is fixedly connected to the inner end of the positioning shaft 46. The two discs 47 are rotatably connected to a connecting rod 48 at a position deviating from the center of the circle. The other end of the connecting rod 48 is rotatably connected to a linkage rod 49. The other end of the linkage rod 49 is rotatably connected to a connecting disc 412. The other end of the connecting disc 412 is connected to a control rod 43. By turning on the servo motor 410 to drive the positioning shaft 46 to rotate synchronously, the positioning shaft 46 drives the disc 47 to rotate synchronously, so that the disc 4 7 cooperates with the connecting rod 48 and the linkage rod 49 to drive the mounting block 411, the connecting plate 412 and the control rod 43 to move back and forth, so that the control rod 43 drives the stirring blades 44 on the connecting shaft 419 to rotate back and forth through the connecting rod, and then the stirring blades 44 scatter the blood powder to be dried. They scatter the blood powder to be dried at a specific frequency and amplitude. This scattering process not only helps the blood powder to be more evenly distributed in the drying cylinder 3 and improves the drying efficiency, but also ensures that the blood powder will not clump or stick during the drying process, thereby ensuring the drying quality and the quality of the final product;

[0037] On both sides of the fixed frame 41, two first bevel gears 413 are rotatably connected, and the two first bevel gears 413 are connected to a second bevel gear 414 rotatably mounted on the fixed frame 41 by meshing. In addition, one end of the rotating rod 42 is fixedly connected to the second bevel gear 414, and on one side of the first bevel gear 413, a first gear 415 is provided, and one side of the first gear 415 is meshedly connected to the second gear 416, and one side of the second gear 416 is meshedly connected to the third gear 417 fixedly mounted on the positioning shaft 46. When the positioning shaft 46 rotates, it drives the third gear 417 to rotate synchronously When the disc 47 rotates, it will drive the meshing second gear 416 to rotate synchronously, and the second gear 416 will drive the meshing first gear 415 to rotate synchronously, so that the first gear 415 will drive the first bevel gear 413 to rotate synchronously, and then the first bevel gear 413 will drive the meshing second bevel gear 414 to rotate, and finally, the stirring blade 44 will drive the rotating rod 42, the control rod 43 and the stirring blade 44 to rotate synchronously, and stir the blood powder in the discharge barrel 2. This stirring not only helps to disperse and mix the blood powder, but also ensures that the blood powder is evenly heated in the subsequent drying process, thereby improving the drying efficiency and product quality;

[0038] A mounting frame 420 is fixedly installed on the top of the fixed frame 41, and the top of the mounting frame 420 is rotatably connected to a rotating shaft 421, one end of the rotating shaft 421 is transmission-connected to the first bevel gear 413 through a synchronous belt pulley transmission member 422, and the other end of the rotating shaft 421 is rotatably connected to a rotating rod 423, and the other end of the rotating rod 423 is rotatably connected to a pushing rod 424, and the other end of the pushing rod 424 is rotatably connected to a sliding rod 425, and the other end of the sliding rod 425 is fixedly connected to a control screen 426, and the outer end of the sliding rod 425 is slidably connected to a sleeve rod 427, and the sleeve rod 427 is fixedly installed on the mounting frame 420. When the first bevel gear When 413 rotates, it drives the rotating shaft 421 to rotate through the synchronous belt pulley transmission part 422, so that the rotating shaft 421 drives the rotating rod 423 to rotate synchronously, and the rotating rod 423 drives the pushing rod 424 to move back and forth, and then the pushing rod 424 drives the sliding rod 425 and the control screen 426 to move back and forth. During the rotation of the drying cylinder 3, it will drive the blood powder to rotate upward. When the blood powder reaches a certain height, it will naturally fall onto the control screen 426 due to the effect of gravity. The reciprocating movement of the control screen 426 and the design of the sieve holes allow the blood powder to be further dispersed and screened in the process of falling, thereby ensuring the uniformity of the blood powder particles and the consistency of the drying effect.

[0039] In the embodiment of the present invention, the servo motor 410 is started to drive the positioning shaft 46 to rotate synchronously, and the rotation of the positioning shaft 46 causes the disc 47 to rotate at the same speed. The movement of the disc 47 drives the connecting rod 48 and the linkage rod 49, so that the mounting block 411, the connecting disc 412 and the control rod 43 move back and forth. The control rod 43 causes the stirring blades 44 on the connecting shaft 419 to reciprocate through the action of the connecting rod. This reciprocating rotation effectively breaks up the blood powder to be dried. They break up the blood powder to be dried at a specific frequency and amplitude. This breaking up not only helps the blood powder to be more evenly distributed in the drying cylinder 3, thereby improving the drying efficiency, but also ensures that the blood powder will not clump or stick together during the drying process, thereby ensuring the drying quality and the quality of the final product.

[0040] During the rotation of the positioning shaft 46, it will drive the third gear 417 to rotate synchronously, and the disc 47 will drive the second gear 416 meshing therewith to rotate synchronously, and the second gear 416 will drive the first gear 415 meshing therewith to rotate synchronously, and the rotation of the first gear 415 will further drive the first bevel gear 413 to rotate synchronously, and the first bevel gear 413 will drive the second bevel gear 414 meshing therewith to rotate, so that the stirring blade 44 will drive the rotating rod 42, the control rod 43 and the stirring blade 44 itself to rotate synchronously, so that the stirring blade 44 effectively stirs the blood powder in the discharge barrel 2, thereby preparing for the subsequent drying process. This stirring not only helps to disperse and mix the blood powder, but also ensures that the blood powder is evenly heated in the subsequent drying process, thereby improving the drying efficiency and product quality;

[0041] In addition, when the first bevel gear 413 rotates, it drives the rotating shaft 421 to rotate through the synchronous belt pulley transmission member 422. The rotation of the rotating shaft 421 will prompt the rotating rod 423 to rotate synchronously. The movement of the rotating rod 423 drives the pushing rod 424 to move back and forth. The reciprocating movement of the pushing rod 424 further drives the sliding rod 425 and the control screen 426 to move back and forth. When the drying cylinder 3 rotates, it will drive the blood powder to rotate upward. When the blood powder reaches a certain height, it will naturally fall onto the control screen 426 due to the effect of gravity. The reciprocating movement of the control screen 426 and the design of the sieve holes enable the blood powder to be further dispersed and screened in the process of falling, thereby ensuring the uniformity of the blood powder particles and the consistency of the drying effect, further improving the efficiency of the drying process and the quality of the final product.

[0042] Embodiment 2: Combination Figure 1As shown, on the basis of Example 1, we have carefully designed and installed rollers 11 on both sides of the top of the support seat 1. These rollers 11 can ensure the smooth movement of the drying cylinder 3 during operation, and the two sides of the drying cylinder 3 are fixedly connected to the rollers 12 that can be smoothly slidably connected to the rollers 11. This design not only enhances the stability of the drying cylinder 3, but also improves its flexibility of movement. In order to drive the entire drying system, we have fixedly installed a driving motor 13 on the support seat 1, and its output end is directly connected to a driving gear 14. The driving gear 14 is tightly meshed with a driven gear ring 15 fixedly installed on the outer wall of the drying cylinder 3, ensuring that the drying cylinder 3 can obtain uniform and continuous power, thereby efficiently completing the drying task.

[0043] In an embodiment of the present invention, by starting the driving motor 13, the synchronous rotation of the driving gear 14 can be achieved. During the rotation process, the driving gear 14 will effectively interact with the meshing driven gear ring 15, thereby driving the driven gear ring 15 to rotate synchronously. As the driven gear ring 15 rotates, the drying drum 3 is placed on the roller 11 and also rotates. At the same time, the stirring blade 44 rotates in the opposite direction to the drying drum 3. This opposite direction rotation setting helps the subsequent drying process and makes the drying effect more uniform and efficient.

[0044] The present invention also discloses a drying process of a blood powder processing and drying device, which specifically comprises the following steps:

[0045] Step 1, after the blood powder to be dried is put into the drying cylinder 3, the servo motor 410 is turned on to drive the positioning shaft 46 to rotate synchronously, the positioning shaft 46 drives the disc 47 to rotate synchronously, the positioning shaft 46 drives the third gear 417 to rotate synchronously when rotating, the disc 47 drives the meshing second gear 416 to rotate synchronously, the second gear 416 drives the meshing first gear 415 to rotate synchronously, so that the first gear 415 drives the first bevel gear 413 to rotate synchronously, so that the first bevel gear 413 drives the meshing second bevel gear 414 to rotate, so that the stirring blade 44 drives the rotating rod 42, the control rod 43 and the stirring blade 44 to rotate synchronously, so that the stirring blade 44 stirs the blood powder in the discharge cylinder 2;

[0046] Step 2: The disc 47 rotates synchronously, so that the disc 47 cooperates with the connecting rod 48 and the linkage rod 49 to drive the mounting block 411, the connecting disc 412, and the control rod 43 to move back and forth, so that the control rod 43 drives the stirring blade 44 located on the connecting shaft 419 to rotate back and forth through the connecting rod, and then the stirring blade 44 breaks up the blood powder to be dried;

[0047] Step 3, when the first bevel gear 413 rotates, it drives the rotating shaft 421 to rotate through the synchronous belt pulley transmission member 422, so that the rotating shaft 421 drives the rotating rod 423 to rotate synchronously, so that the rotating rod 423 drives the pushing rod 424 to move back and forth, so that the pushing rod 424 drives the sliding rod 425 and the control screen 426 to move back and forth, and when the drying cylinder 3 rotates, it drives the blood powder to rotate upward, and when the blood powder moves to the position above the control screen 426, due to the effect of gravity, it will naturally fall onto the control screen 426, so that the blood powder can be dispersed and screened in the process of falling;

[0048] Step 4: Dry the blood powder using the drying cylinder 3 , and the dried blood powder is discharged through the discharge cylinder 2 .
