Description

Technical Field

[0001] This utility model belongs to the field of drying equipment technology, and specifically relates to a device for controlling powder drying. Background Technology

[0002] A powder drying control device is an industrial drying equipment that integrates a temperature control system (such as electric heating, steam heat exchange, infrared or microwave heating, etc.). It can dynamically adjust the heating power or hot air temperature according to the characteristics of the powder material (such as heat sensitivity, moisture content, particle size, etc.) to ensure the consistency of drying effect, energy efficiency and product quality.

[0003] In industries such as chemical, pharmaceutical, and food processing, drying powdered materials is a crucial process. Temperature-controlled powder dryers, by precisely adjusting parameters such as heating temperature, efficiently evaporate moisture or solvents from the material, thereby obtaining a uniformly dried powder product. However, existing technologies still have the following problems in practical applications:

[0004] After drying, the powder is prone to clumping and has low screening efficiency.

[0005] During the drying process, the powder is conveyed by a spiral conveyor and moves towards the discharge port inside the heating cylinder. The powder particles may agglomerate due to uneven local heating, forming lumps of varying sizes. These lumps can affect the flowability of the powder, packaging efficiency, and even lead to quality problems in subsequent processes. The conventional method is to use a crushing device at the discharge port, and then the agglomerated powder is crushed by the crushing device and then screened through a fixed screen. However, such a fixed screen results in extremely low powder screening efficiency, which greatly reduces the discharge efficiency of powder drying. Therefore, a device for controlling powder drying is provided.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] The purpose of this invention is to provide a device for controlling powder drying, so as to solve the problems of powder agglomeration and low screening efficiency after drying in the prior art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A device for controlling powder drying includes a heating cylinder with a heating function. A feed hopper is fixedly connected to the feed inlet on the top right side of the heating cylinder. A drive motor is fixedly connected to the middle of the right end of the heating cylinder. The output shaft of the drive motor extends to the inside of the heating cylinder and is fixedly connected to a spiral hinge. The end of the spiral hinge shaft away from the drive motor extends to the outside of the heating cylinder and is connected to a pulverizing component between it and the discharge port. The discharge port is located on the left side of the bottom end of the heating cylinder. Two symmetrically arranged guide plates are fixedly connected inside the discharge port. A movable frame is provided below the two guide plates. A screen is fixedly connected to the inner wall of the movable frame. A transmission component is connected between the pulverizing component and the discharge port. The transmission component is also connected to the outer wall of the movable frame.

[0010] Preferably, the crushing assembly includes two crushing rollers disposed between the two guide plates and the moving frame. Both crushing rollers are rotatably connected to the discharge port. The left end shafts of both crushing rollers extend to the outside of the discharge port and are fixedly connected to gears. The two gears mesh with each other. A second sprocket is fixedly connected to the outside of the left end shaft extension of the crushing roller near the rear side of the heating cylinder. The second sprocket is connected to a first sprocket via chain drive. The first sprocket is fixed to the outside of the spiral hinge shaft end extending away from the drive motor on the spiral hinge.

[0011] Preferably, the transmission assembly includes a transmission column fixedly connected to the edge of the gear surface near the front side of the heating cylinder, and a Z-shaped rod movably sleeved on the outer side of the transmission column, the Z-shaped rod having a transmission channel that cooperates with the transmission column.

[0012] Preferably, the length of the transmission channel is larger than the outer diameter of the gear, and the inner width of the transmission channel is equal to the diameter of the transmission column.

[0013] Preferably, baffle plates are fixedly connected to both sides of the movable frame, and sliding seats with I-shaped vertical cross-sections are fixedly connected to the middle of the side walls of the two baffle plates facing away from each other. The sliding seats are slidably connected to the sliding grooves opened on the outer wall of the discharge port, and the middle of the outer side of the left sliding seat is fixedly connected to the bottom end of the Z-shaped rod by a connecting rod.

[0014] Preferably, the length and width of the baffle plate are greater than the length and width of the sliding groove, and both ends of the baffle plate are movably inserted to the outside of the discharge port.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The powder drying control device of this utility model allows the powder to be dried to enter through the feed hopper, and then the internal spiral hinge is driven to rotate by the drive motor, so that the first sprocket drives the second sprocket to rotate clockwise through the chain, and with the meshing of the two gears, the two crushing rollers rotate relative to each other and crush the powder falling between the two guide plates. The clumps of powder fall together on the screen after crushing. The rotation of the gears also drives the transmission column to rotate. With the setting of the transmission channel and the Z-shaped rod, and with the action of the connecting rod, the moving frame drives the screen to move back and forth in the discharge port, so as to efficiently screen the falling powder and avoid the screen being fixed, which greatly reduces the efficiency of powder screening after drying.

[0024] After drying, the powder is prone to clumping and has low screening efficiency.

[0025] During the drying process, the powder is conveyed in the heating cylinder 1 towards the discharge port 13 using a spiral hinge. The powder particles may agglomerate due to uneven local heating, forming lumps of varying sizes. These lumps will affect the flowability of the powder, packaging efficiency, and may even lead to quality problems in subsequent processes such as tableting, mixing, and granulation. The conventional method is to use a crushing device set at the discharge port 13, and then the agglomerated powder is crushed by the crushing device and then screened through a fixed screen 135. However, such a fixed screen 135 will result in extremely low powder screening efficiency, which will greatly reduce the discharge efficiency of powder drying.

[0026] See attached document Figs. 1-2 A device for controlling powder drying includes a heating cylinder 1 with a heating function. A feed hopper 11 is fixedly connected to the feed inlet on the top right side of the heating cylinder 1. A drive motor 12 is fixedly connected to the middle of the right end of the heating cylinder 1. The output shaft of the drive motor 12 extends to the inside of the heating cylinder 1 and is fixedly connected to a spiral hinge. The end of the spiral hinge shaft 14, which is away from the drive motor 12, extends to the outside of the heating cylinder 1 and is connected to a crushing component between it and the discharge port 13. The discharge port 13 is located on the left side of the bottom end of the heating cylinder 1. Two symmetrically arranged guide plates 131 are fixedly connected inside the discharge port 13. A movable frame 134 is provided below the two guide plates 131. A screen 135 is fixedly connected to the inner wall of the movable frame 134. A transmission component 2 is connected between the crushing component and the discharge port 13. The transmission component 2 is also connected to the outer wall of the movable frame 134.

[0027] Multiple heating rods are provided on the inner side of the inner wall of the heating cylinder 1. This is existing technology and is not shown in the attached drawings, so it will not be described in detail here.

[0028] The length of the moving frame 134 is smaller than the length of the sliding groove, and the front and rear ends of the moving frame 134 are reserved with clearance for reciprocating movement.

[0029] Furthermore, such as Figs. 1-2As shown, the crushing assembly includes two crushing rollers 132 disposed between two guide plates 131 and a moving frame 134. Both crushing rollers 132 are rotatably connected to the discharge port 13. The left end shafts of both crushing rollers 132 extend to the outside of the discharge port 13 and are fixedly connected to gears 133. The two gears 133 mesh with each other. A second sprocket 17 is fixedly connected to the outside of the extension of the left end shaft of the crushing roller 132 near the rear side of the heating cylinder 1. The second sprocket 17 is connected to a first sprocket 15 via a chain 16. The first sprocket 15 is fixedly connected to the outside of the spiral hinge shaft 14 extending away from the drive motor 12 on the spiral hinge.

[0030] Furthermore, such as Figs. 1-2 As shown, in order to drive the screen 135 to reciprocate using the aforementioned pulverizing assembly, and to efficiently screen the powder on the surface of the screen 135, the transmission assembly 2 includes a transmission column 26 fixedly connected to the edge of the gear 133 near the front side of the heating cylinder 1. A Z-shaped rod 24 is movably sleeved on the outer side of the transmission column 26. A transmission channel 25 that cooperates with the transmission column 26 is opened on the Z-shaped rod 24. The length of the transmission channel 25 is larger than the outer diameter of the gear 133, and the inner width of the transmission channel 25 is larger than the outer diameter of the gear 133. The diameters of the moving columns 26 are equal. Both sides of the moving frame 134 are fixed with baffle plates 21. The middle of the side wall of the two baffle plates 21 facing away from each other is fixed with a sliding seat 22 with a vertical cross section of I-shaped structure. The sliding seats 22 are slidably connected to the sliding groove opened in the outer wall of the discharge port 13. The middle of the outer side of the left sliding seat 22 is fixed to the bottom end of the Z-shaped rod 24 through the connecting rod 23. The length and width of the baffle plate 21 are larger than the length and width of the sliding groove. Both ends of the baffle plate 21 are movably inserted into the outer side of the discharge port 13.

[0031] The baffle plate 21 can block the sliding groove and prevent powder from leaking out from the sliding groove;

[0032] The inner width of the transmission channel 25 is equal to the diameter of the transmission column 26 in order to prevent the sliding seat 22 from moving within the sliding groove.

[0033] In actual use, the powder to be dried enters through the feed hopper 11, and then the internal spiral hinge is driven to rotate by the drive motor 12. This causes the first sprocket 15 to drive the second sprocket 17 to rotate clockwise via the chain 16. In conjunction with the meshing of the two gears 133, the two crushing rollers 132 rotate relative to each other, crushing the powder falling between the two guide plates 131. The clumps of powder fall onto the screen 135 after crushing. The rotation of the gears 133 also drives the transmission column 26 to rotate. In conjunction with the transmission channel 25 and the Z-shaped rod 24, and the action of the connecting rod 23, the moving frame 134 drives the screen 135 to move back and forth within the discharge port 13. This allows for efficient screening of the falling powder, avoiding a fixed screen 135 which would greatly reduce the efficiency of powder screening after drying.

[0034] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
