A drying device for powder materials used in biochemical industry

Abstract

This invention discloses a drying device for powder materials used in biochemical engineering, relating to the field of powder drying technology. It includes a drying chamber with a feeding cylinder on one side of the top. A stirring motor is fixedly connected to the side of the feeding cylinder via a mounting plate. A drying pipe is fixedly connected to the side of the drying chamber vertically. When the bottom rotating shaft drives the screen to rotate, larger powder clumps at the top of the screen gradually concentrate towards the area where the crushing rod is located. Under the power of the blower motor, the blower blades blow air upwards from the bottom. The upward blowing of air inside the air inlet pipe creates a vacuum inside the suction pipe, drawing in air and powder from below the metal ring. Finally, the powder enters the drying pipe under the obstruction of the isolation net. When ejected from the drying pipe, lighter and smaller powder particles are thrown between the receiving baffle and the side wall of the drying chamber, while larger particles fall into the crushing cylinder, achieving the purpose of classifying and re-drying the materials.

[0020] The drying device for powder materials for biochemical industry can re-dry smaller lumps after crushing and grinding by arranging a drying tube, and can selectively enter the crushing tube for re-processing after selection. When the bottom rotating shaft drives the screening net to rotate and screen, the larger powder lumps on the top of the screening net will gradually concentrate on the area where the crushing rods are located, and the larger lumps will be broken by the collision between the crushing rods and the baking of the bottom heating tube. Under the power of the blower motor, the blower blades blow the air at the bottom upward, and the air inside the air inlet pipe is blown upward to form a vacuum inside the suction pipe, so that the air under the metal ring and the powder are sucked together, and finally enter the drying tube under the obstruction of the isolation net. When sprayed out from the drying tube, the lighter and smaller powders are thrown between the receiving partition and the side wall of the drying box, and the larger ones fall into the crushing tube, so as to achieve the purpose of classifying and re-drying the materials.

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0033] See also Figures 1 to 10The present invention provides a technical solution: it includes a drying box 2, a fixed base 3 is provided at the bottom of the drying box 2, four supporting legs 5 are fixedly connected to the four corners of the bottom of the fixed base 3, and a non-slip pad 6 is fixedly connected to the bottom of each supporting leg 5, and the drying box 2 is supported by the fixed base 3 on the top of the supporting leg 5, and the stability of the whole device is ensured by the non-slip pad 6, a feeding cylinder 1 is provided on one side of the top of the drying box 2, and a stirring motor 10 is fixedly connected to the side of the feeding cylinder 1 through a mounting plate 12, and the stirring motor 10 is located in the middle of the top of the drying box 2, and a positioning plate 13 is fixedly connected to the bottom of the stirring motor 10, and the positioning plate 13 is fixedly connected to the middle of the top of the drying box 2 by bolts, and the mounting plate 12 is fixedly connected to the outer wall of the feeding cylinder 1 by bolts. A closure cover 11 is fixedly connected to one side of the top through a connecting hinge 14, and is integrally installed on the top of the drying box 2 with the stirring motor 10 by using a positioning plate 13. After the positioning plate 13 is installed on the top of the drying box 2, it can provide sufficient torque when the stirring motor 10 is working to prevent the mounting plate 12 from bearing too much torque. A drying pipe 9 is fixedly connected to the side of the drying box 2 in the vertical direction. The top of the drying pipe 9 is bent and passes through the side of the drying box 2. By setting the drying pipe 9, the powder material can be dried by using the drying pipe 9. A crushing cylinder 20 is arranged inside the drying box 2, and a grinding cone 37 for grinding the powder material is arranged inside the crushing cylinder 20. A discharge cylinder 4 is arranged at the bottom of the drying box 2, and a screening net 32 ​​is arranged between the crushing cylinder 20 and the discharge cylinder 4. The bottom of the inner wall of the drying box 2 is fixedly connected with a bottom heating pipe 45. After the powder material is added, the bottom heating pipe 45 inside the drying box 2 can start working to heat the internal space. After the temperature of the internal space rises, the moisture in the powder material can be dried as soon as possible. The bottom of the drying box 2 is a hollow trapezoidal platform with an opening upward. The discharge barrel 4 is fixedly connected to the middle position of the downward protrusion of the bottom of the drying box 2. An insertion hole 17 with the same width as the inner wall of the discharge barrel 4 is opened on the side of the discharge barrel 4. A bottom plate 16 that closes the discharge barrel 4 is inserted into the insertion hole 17. Two pull-out handles 15 are symmetrically arranged on the outer wall of the bottom plate 16. When it is necessary to discharge the secreted material after drying in the drying box 2, the bottom plate 16 can be pulled out by pulling out the handles 15, so that the powder accumulated at the bottom of the drying box 2 is discharged from the discharge barrel 4. After the powder material in the drying box 2 is reduced, the powder material can be added to the drying box 2 again through the feeding barrel 1.

[0034] A cross-connecting plate 25 is fixedly connected to the middle of the inner wall of the drying box 2 in the horizontal direction of front and back, and a grinding cylinder 20 extending upward in the vertical direction is fixedly connected to the middle of the top of the cross-connecting plate 25. A spiral heating tube 41 for heating the grinding cylinder 20 is embedded inside the bottom wall and the side wall of the grinding cylinder 20. When working, the spiral heating tube 41 can heat the grinding cylinder 20. When the powder material inside the grinding cylinder 20 is dried and ground, heat can be continuously provided to the grinding cylinder 20 for heating. The output shaft of the stirring motor 10 vertically penetrates the top wall of the drying box 2 downward, and the output shaft is connected to the top wall of the drying box 2 through a bearing. The output shaft of the stirring motor 10 is fixedly connected to the grinding cylinder 2. 0, the bottom side of the stirring shaft 18 is fixedly connected with cutting rods 19 in an annular array at equal intervals, the bottom of the stirring shaft 18 is fixedly connected to the middle of the top of the grinding cone 37, the inner bottom wall of the crushing cylinder 20 is hollowed out to form a conical cavity that fits the grinding cone 37, and the middle part of the cross-connecting plate 25 is provided with a leakage hole 42 extending to the inside of the crushing cylinder 20. When the powder is ground and dried, the stirring shaft 18 is driven by a motor to rotate, so that the stirring shaft 18 drives the cutting rod 19 and the grinding cone 37 to rotate, and the cutting rod 19 at the top stirs and crushes the powder, and smaller lumps are ground through the gap between the crushing cylinder 20 and the grinding cone 37, and the lumps are broken while drying;

[0035] A bottom rotating shaft 36 is fixedly connected to the middle of the bottom of the grinding cone 37 in a vertical downward direction, and a rotating disk 34 is fixedly connected to the bottom of the bottom rotating shaft 36. The outer periphery of the screening net 32 ​​is supported by the screening frame 24. An intermediate rod 33 is horizontally arranged in the middle of the screening frame 24. An insertion rod 35 is fixedly connected to the middle top of the intermediate rod 33 and is vertically upward. A circular hole is provided on the rotating disk 34, and the middle part of the insertion rod 35 is inserted into the inside of the circular hole. When the grinding cone 37 at the top rotates, the bottom rotating shaft 36 is driven to rotate the rotating disk 34, and the insertion rod 35 can drive the intermediate rod 33 to rotate. Since the insertion rod 35 can be raised and lowered in the circular hole, the rotating disk 34 drives the screening net 32 ​​to swing in a circle. A plurality of support plates 31 are fixedly connected to the inner wall of the drying box 2. The bottom of the screening frame 24 is movably connected to the rotating rod 30 through a bearing rod. The other end of the rotating rod 30 is movably connected to the top of the support plate 31 through the bearing rod. When the intermediate rod 33 drives the screening net 32 ​​to swing, the support plate 31 can not only use the screening frame 24 to support the screening net 32, but also use the rotating rod 30 to help the screening frame 24 rotate, so that the dried powder can be screened by the screening net 32.

[0036] When in use, first open the closing cover 11 on the top of the feeding barrel 1, pour the powder material to be dried into the feeding barrel 1, and the added powder material falls into the inside of the crushing barrel 20. After the stirring motor 10 is turned on by the controller, the cutting rod 19 and the grinding cone 37 are driven to rotate by the rotation of the stirring shaft 18. At the same time, the spiral heating tube 41 is energized by the controller to heat the crushing barrel 20, so that the powder inside is dried and ground. Finally, the ground and dried powder falls from the leakage hole 42, and after falling on the screening net 32, the rotating disk 34 can be rotated under the drive of the bottom rotating shaft 36, so that the insertion rod 35 drives the middle rod 33 to shake. Since the two ends of the middle rod 33 are connected to the sieving frame 24, and the bottom of the sieving frame 24 is movably supported by the rotating rod 30, it can be ensured that the sieving frame 24 drives the screening net 32 ​​to shake. When the powder on the top of the screening net 32 ​​is screened, the smaller powder will fall to the bottom of the drying box 2. The bottom heating tube 45 heats the inside of the drying box 2 to heat and dry the powder at the bottom. Example

A closure cover 11 is fixedly connected to one side of the top through a connecting hinge 14, and is integrally installed on the top of the drying box 2 with the stirring motor 10 by using a positioning plate 13. After the positioning plate 13 is installed on the top of the drying box 2, it can provide sufficient torque when the stirring motor 10 is working to prevent the mounting plate 12 from bearing too much torque. A drying pipe 9 is fixedly connected to the side of the drying box 2 in the vertical direction. The top of the drying pipe 9 is bent and passes through the side of the drying box 2. By setting the drying pipe 9, the powder material can be dried by using the drying pipe 9. A crushing cylinder 20 is arranged inside the drying box 2, and a grinding cone 37 for grinding the powder material is arranged inside the crushing cylinder 20. A discharge cylinder 4 is arranged at the bottom of the drying box 2, and a screening net 32 ​​is arranged between the crushing cylinder 20 and the discharge cylinder 4. The bottom of the inner wall of the drying box 2 is fixedly connected with a bottom heating pipe 45. After the powder material is added, the bottom heating pipe 45 inside the drying box 2 can start working to heat the internal space. After the temperature of the internal space rises, the moisture in the powder material can be dried as soon as possible. The bottom of the drying box 2 is a hollow trapezoidal platform with an opening upward. The discharge barrel 4 is fixedly connected to the middle position of the downward protrusion of the bottom of the drying box 2. An insertion hole 17 with the same width as the inner wall of the discharge barrel 4 is opened on the side of the discharge barrel 4. A bottom plate 16 that closes the discharge barrel 4 is inserted into the insertion hole 17. Two pull-out handles 15 are symmetrically arranged on the outer wall of the bottom plate 16. When it is necessary to discharge the secreted material after drying in the drying box 2, the bottom plate 16 can be pulled out by pulling out the handles 15, so that the powder accumulated at the bottom of the drying box 2 is discharged from the discharge barrel 4. After the powder material in the drying box 2 is reduced, the powder material can be added to the drying box 2 again through the feeding barrel 1.

[0038] A bottom rotating shaft 36 is fixedly connected to the middle of the bottom of the grinding cone 37 in a vertical downward direction, and a rotating disk 34 is fixedly connected to the bottom of the bottom rotating shaft 36. The outer periphery of the screening net 32 ​​is supported by the screening frame 24. An intermediate rod 33 is horizontally arranged in the middle of the screening frame 24. An insertion rod 35 is fixedly connected to the middle top of the intermediate rod 33 and is vertically upward. A circular hole is provided on the rotating disk 34, and the middle part of the insertion rod 35 is inserted into the inside of the circular hole. When the grinding cone 37 at the top rotates, the bottom rotating shaft 36 is driven to rotate the rotating disk 34, and the insertion rod 35 can drive the intermediate rod 33 to rotate. Since the insertion rod 35 can be lifted and lowered in the circular hole, the rotating disk 34 drives the screening net 32 ​​to swing in a circle. The inner wall of the drying box 2 is fixedly connected with a plurality of support plates 31. The bottom of the screening frame 24 is movably connected with a rotating rod 30 through a bearing rod. The other end of the rotating rod 30 is movably connected to the top of the support plate 31 through the bearing rod. When the intermediate rod 33 drives the screening net 32 ​​to swing, the support plate 31 can not only use the screening frame 24 to support the screening net 32, but also use the rotating rod 30 to help the screening frame 24 rotate, so that the dried powder can be screened by the screening net 32.

[0039] The bottom wall of the drying pipe 9 is movably connected with the blower blade 43 through a bearing, the outer side surface of the drying box 2 is fixedly connected with the blower motor 7 through a mounting seat, the output shaft of the blower motor 7 is vertically upward and fixedly connected with the blower blade 43, the side wall of the drying pipe 9 is located above the blower blade 43 and is fixedly connected with a bifurcated pipe 22, the top middle of the bifurcated pipe 22 is fixedly connected with an air inlet pipe 8, the other end of the air inlet pipe 8 is bent downward and connected with the space below the blower blade 43, the bottom of the bifurcated pipe 22 is fixedly connected with a suction pipe 23, the bottom of the suction pipe 23 is fixedly connected with a cross 28 through a metal ring 21, the end of the cross 28 is fixedly connected to the top of the sieving frame 24, The motor 7 drives the fan blades 43 to blow air, so that the air at the bottom of the fan blades 43 flows upward quickly, and the air at the bottom is supplemented through the air inlet pipe 8. Since the air inside the air inlet pipe 8 enters from the bifurcated pipe 22, and the bifurcated pipe 22 is inclined upward to the direction of the blasted air, the air can only enter through the suction pipe 23, and the small agglomerates on the screening net 32 ​​are sucked in by the flowing air, and after being blocked by the isolation net 44, they are thrown into the interior of the drying tube 9 under the action of inertia. The sieving frame 24 is tilted left and right, and the side of the sieving frame 24 close to the bifurcated pipe 22 is located at a low position. The left and right extensions of the sieving frame 24 are isosceles trapezoidal, and the sieving frame 24 is close to the bifurcated pipe 22. One side is a narrow side. The top of the sifting frame 24 is located below the metal ring 21 and is provided with crushing rods 29 in a rectangular array. When the sifting frame 24 is shaken, due to the lower position close to the air inlet pipe 8, the powder agglomerates on the top of the screening net 32 ​​can gradually roll to the position of the crushing rods 29 during shaking. At the same time, after entering between the crushing rods 29, they will be impacted and broken during shaking. A glass partition 40 is provided inside the drying tube 9. A heating chamber 39 is formed between the glass partition 40 and the inner wall of the drying tube 9. Vertical heating tubes 38 are distributed in a circular array inside the heating chamber 39. When the powder inside the drying tube 9 rises with the air, the powder agglomerates in the vertical heating tubes 38 are crushed. 8 is heated and dried, and the temperature of the air inside the drying box 2 is increased at the same time. The top of the crushing cylinder 20 is fixedly connected with a return connecting plate 27, and the top of the return connecting plate 27 is fixedly connected with a receiving partition 26. The side of the receiving partition 26 is fixedly connected to the inner wall of the drying box 2, and the receiving partition 26 is arranged on the side away from the drying tube 9. The powder sprayed from the top of the drying tube 9 with the air is thrown horizontally. The lighter powder will be directly blown away and fall between the receiving partition 26 and the drying box 2, and finally directly accumulate at the bottom of the drying box 2. The heavier lumps will fall into the crushing cylinder 20 or on the return connecting plate 27, and will eventually slide into the inside of the crushing cylinder 20 for drying again.

[0040] When in use, the powder dried by the crushing cylinder 20 falls on the screening net 32, and the insertion rod 35 can follow the rotating disk 34 to make a circular motion under the drive of the bottom rotating shaft 36. Since the two ends of the middle rod 33 are connected to the screening frame 24, and the bottom of the screening frame 24 is movably supported by the rotating rod 30, it can be ensured that the screening frame 24 drives the screening net 32 ​​to shake, and when the powder on the top of the screening net 32 ​​is screened, the smaller powder will fall to the bottom of the drying box 2, and the bottom heating tube 45 can heat and dry the powder at the bottom by heating the inside of the drying box 2. The larger agglomerates stay on the screening net 32. When the screening frame 24 is shaken, the powder agglomerates on the top of the screening net 32 ​​can gradually roll to the position of the crushing rods 29 due to the lower position close to the air inlet pipe 8 when shaking. At the same time, after entering between the crushing rods 29, they will be impacted and broken when shaking. After the blower motor 7 is powered on, the blower blades 43 are driven by the blower motor 7 to blow air, so that the air at the bottom of the blower blades 43 flows upward quickly, and the air at the bottom is supplemented through the air inlet pipe 8. Since the air inside the air inlet pipe 8 is from the bifurcated pipe The air can only enter through the suction pipe 23, and the flowing air is used to suck the small agglomerates on the screening net 32. After being blocked by the isolation net 44, they are thrown into the drying pipe 9 under the action of inertia. When the powder inside the drying pipe 9 rises with the air, it is dried under the heating of the vertical heating pipe 38, and the temperature of the air inside the drying box 2 is increased. The powder ejected from the top of the drying pipe 9 with the air is thrown horizontally, and the lighter powder will be directly blown away and fall between the receiving partition 26 and the drying box 2. Finally, it is directly accumulated at the bottom of the drying box 2. The heavier lumps will fall into the crushing cylinder 20 or on the reflux connecting plate 27, and will eventually slide into the inside of the crushing cylinder 20 for further drying. When the dried powder material needs to be discharged, the bottom plate 16 is pulled out by pulling the handle 15. After the bottom of the discharge cylinder 4 is opened, the dried powder material at the bottom of the drying box 2 can be automatically discharged. After the bottom plate 16 is inserted to close the discharge cylinder 4, the powder to be dried is added to the drying box 2 through the feeding cylinder 1, so as to achieve the purpose of continuous drying of the powder material.
