Abstract
Description
Technical Field
[0001] This utility model relates to the field of wheat processing technology, specifically to a bran drying device. Background Technology
[0002] As a by-product of grain processing, wheat bran is rich in dietary fiber and protein, but its high humidity (initial moisture content is usually 12%-18%) and tendency to clump together make it prone to mold during storage and transportation. Therefore, wheat bran needs to be dried.
[0003] Traditional drying equipment (such as drum dryers or box dryers) mostly uses high-temperature airflow for direct heating. The contact time between hot air and materials is short, resulting in low thermal efficiency. This leads to the need to increase the power consumption of the hot air blower in order to improve the drying effect, resulting in energy waste. Utility Model Content
[0004] To address the shortcomings of existing technologies, such as short contact time between hot air and materials and low thermal efficiency in traditional drying equipment, which necessitates increased power consumption of the hot air blower to improve drying effect and thus waste energy, this utility model provides a bran drying device.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] This utility model discloses a bran drying device, including an inclined feeding pipe. A conveying pipe connected to the bottom end of the inclined feeding pipe is fixedly connected to the inclined feeding pipe. A discharge box is fixedly connected to the end of the conveying pipe away from the inclined feeding pipe. A discharge component is provided on the discharge box. A hot air fan is provided on one side of the inclined feeding pipe. A cleaning component for cleaning the inner wall of the conveying pipe is provided inside the conveying pipe. A uniform feeding component is provided at the top end of the inclined feeding pipe.
[0007] As a preferred embodiment of the present invention, the discharge assembly includes an induction-type receiving device disposed at the bottom of the discharge box and a Roots blower disposed at the top of the discharge box and connected to the discharge box.
[0008] As a preferred technical solution of this utility model, the uniform feeding assembly includes a feeding shell fixedly connected to the top of the inclined feeding pipe, a spiral shaft rotatably connected inside the feeding shell, spiral blades provided on the outer wall of the spiral shaft, a feeding motor for driving the spiral shaft to rotate provided at one end of the outer wall of the feeding shell, and a feeding bin fixedly connected to one side of the upper surface of the feeding shell.
[0009] As a preferred embodiment of this utility model, an inlet for connecting the feeding hopper and the feeding shell is provided on one side of the upper surface of the feeding shell, and a discharge port for connecting the feeding shell and the inclined feeding pipe is provided on the lower surface of the feeding shell near the inclined feeding pipe.
[0010] As a preferred embodiment of this utility model, the cleaning assembly includes a cleaning motor fixedly connected to one side of the outer wall of the conveying pipe. A rotating rod is fixedly connected to the output end of the cleaning motor. A sliding rod is fixedly connected to the side of the outer wall of the conveying pipe near the rotating rod. A limit block is fixedly connected to the end of the sliding rod away from the conveying pipe. A striking block is slidably connected to the sliding rod. A spring is fixedly connected to the end of the outer wall of the striking block near the limit block. A sliding groove is provided on the sliding block. A sliding block that matches the sliding groove is fixedly connected to one side of the outer wall of the rotating rod.
[0011] As a preferred embodiment of this utility model, a drain valve is provided at the bottom end of the conveying pipe.
[0012] The beneficial effects of this utility model are:
[0013] This type of bran drying equipment, through the cooperation of an inclined feed pipe, a conveying pipe, a discharge box, a discharge component, and a hot air blower, allows bran to enter the inclined feed pipe, pass through the conveying pipe and the discharge box, and then be discharged through the discharge component. After the bran enters the inclined feed pipe, the hot air discharged by the hot air blower mixes with the bran and makes full contact with the bran in the conveying pipe to dry the bran. After entering the discharge component, the hot air is separated from the bran and discharged, increasing the contact time between the hot air and the bran, thereby effectively improving the drying efficiency of the equipment for bran, reducing energy consumption, and reducing energy waste.
[0014] This type of bran drying equipment, through the cooperation of a cleaning motor, rotating rod, sliding rod, limit block, slider, spring, chute, and drain valve, works as follows: After the bran is dried, the cleaning motor is turned on, the rotating rod drives the slider to rotate, and when the slider rotates into the chute, it continues to rotate, driving the chute and slider to move towards the limit block, while compressing the spring. When the slider rotates out of the chute, the spring drives the slider to reset, and the slider strikes the conveying pipe, causing the bran adhering to the inner wall of the conveying pipe to fall. After the cleaning component strikes the conveying pipe, the bran adhering to the inner wall of the conveying pipe falls to the bottom of the conveying pipe. At this time, the drain valve is opened to discharge the bran that has fallen to the bottom of the conveying pipe from the conveying pipe, thereby minimizing the risk of the bran adhering to the inner wall of the conveying pipe and deteriorating, which would affect the quality of the dried bran in subsequent use.
[0015] This type of bran drying equipment, through the cooperation of the feeding shell, spiral shaft, spiral blades, feeding motor, feeding hopper, feeding port and discharging port, allows the bran to be poured into the feeding hopper during use. The feeding motor is then started, and the bran in the feeding hopper enters the feeding shell through the feeding port. The spiral shaft and spiral blades rotate, conveying the bran to the discharging port and into the inclined feeding pipe, thus ensuring the uniformity of bran feeding. At the same time, the bran feeding speed can be adjusted by adjusting the rotation speed of the spiral shaft driven by the feeding motor. Attached Figure Description

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0022] Example: Refer to Figure 1 and Figure 2The present invention relates to a bran drying device, comprising an inclined feeding pipe 1, a conveying pipe 2 connected to the bottom end of the inclined feeding pipe 1 and communicating with the inclined feeding pipe 1, a discharge box 3 connected to the end of the conveying pipe 2 away from the inclined feeding pipe 1, a discharge assembly 4 provided on the discharge box 3, the discharge assembly 4 including an induction type receiving device 41 provided at the bottom of the discharge box 3 and a Roots blower 42 provided at the top of the discharge box 3 and communicating with the discharge box 3, and a hot air blower 5 provided on one side of the inclined feeding pipe 1;
[0023] In use, first turn on the Roots blower 42 and the hot air blower 5. The bran first enters the inclined feed pipe 1. Under the influence of negative pressure, it passes through the inclined feed pipe 1 and the conveying pipe 2 and then enters the discharge box 3. At the same time, as the bran moves towards the hot air blower 5, the hot air sprayed by the hot air blower 5 mixes with the bran to dry it. At the same time, when the hot air sprayed by the hot air blower 5 comes into contact with the bran, it can impact the bran and break up the clumps caused by static electricity and humidity. Since the width of the discharge box 3 is larger than the diameter of the conveying pipe 2, when the bran enters the discharge box 3 through the conveying pipe 2, the airflow speed carrying the bran decreases. The bran falls to the bottom of the discharge box 3 and is discharged through the induced feeder 41. After drying the bran, the gas carrying moisture is discharged through the Roots blower 42.
[0024] Reference Figure 1 and Figure 3 The conveying pipe 2 is equipped with a cleaning component 6 for cleaning the inner wall of the conveying pipe 2. The cleaning component 6 includes a cleaning motor 61 fixedly connected to one side of the outer wall of the conveying pipe 2. A rotating rod 62 is fixedly connected to the output end of the cleaning motor 61. A sliding rod 63 is fixedly connected to the side of the outer wall of the conveying pipe 2 near the rotating rod 62. A limit block 64 is fixedly connected to the end of the sliding rod 63 away from the conveying pipe 2. A striking block 65 is slidably connected to the sliding rod 63. A spring 66 is fixedly connected to the end of the outer wall of the striking block 65 near the limit block 64. A groove 67 is opened on the striking block 65. A slider 68 that matches the groove 67 is fixedly connected to one side of the outer wall of the rotating rod 62.
[0025] After the bran is dried, the hot air blower 5 and the Roots blower 42 are turned off, and the cleaning motor 61 is turned on. The cleaning motor 61 can drive the rotating rod 62 to rotate, which in turn drives the striking block 65 to rotate. When the striking block 65 rotates into the slide groove 67, it continues to rotate, and drives the slide groove 67 and the slider 68 to move towards the limit block 64. At the same time, the spring 66 is compressed. When the slider 68 rotates to disengage from the slide groove 67, the spring 66 drives the striking block 65 to reset. The striking block 65 strikes the conveying pipe 2, causing the bran attached to the inner wall of the conveying pipe 2 to fall down, so as to avoid the bran from deteriorating and affecting the quality of the dried bran in subsequent use. A drain valve 8 is provided at the bottom of the conveying pipe 2. After the cleaning component 6 strikes the conveying pipe 2, the bran attached to the inner wall of the conveying pipe 2 falls to the bottom of the conveying pipe 2. At this time, the drain valve 8 is opened to discharge the bran that has fallen to the bottom of the conveying pipe 2 from the conveying pipe 2.
[0026] Reference Figure 1 , Figure 2 and Figure 3 The top end of the inclined feed pipe 1 is provided with a uniform feed assembly 7. The uniform feed assembly 7 includes a feed housing 71 fixedly connected to the top end of the inclined feed pipe 1. A spiral shaft 72 is rotatably connected inside the feed housing 71. Spiral blades 73 are provided on the outer wall of the spiral shaft 72. A feed motor 74 for driving the spiral shaft 72 to rotate is provided at one end of the outer wall of the feed housing 71. The Roots blower 42, hot air blower 5, cleaning motor 61 and feed motor 74 are all electrically connected to the control panel (not shown in the figure). A feed bin 75 is fixedly connected to one side of the upper surface of the feed housing 71. A feed port 76 for connecting the feed bin 75 and the feed housing 71 is opened on one side of the upper surface of the feed housing 71. A discharge port 77 for connecting the feed housing 71 and the inclined feed pipe 1 is opened on the lower surface of the feed housing 71 near the inclined feed pipe 1.
[0027] In use, the bran is poured into the feed hopper 75, and the feed motor 74 is started. The bran in the feed hopper 75 enters the feed housing 71 through the feed inlet 76. The screw shaft 72 and the screw blades 73 rotate, conveying the bran to the discharge port 77 and into the inclined feed pipe 1 through the discharge port 77, thereby ensuring the uniformity of bran feeding. At the same time, the bran feeding speed can be adjusted by adjusting the rotation speed of the screw shaft 72 driven by the feed motor 74.
[0028] The working principle of this utility model is as follows:
[0029] During operation, when using the bran, pour it into the feed hopper 75, start the feed motor 74, and the bran in the feed hopper 75 enters the feed housing 71 through the feed inlet 76. The spiral shaft 72 and spiral blades 73 rotate, conveying the bran to the discharge port 77 and into the inclined feed pipe 1 through the discharge port 77.
[0030] Then, the Roots blower 42 and the hot air blower 5 are turned on. The bran first enters the inclined feed pipe 1. Under the influence of negative pressure, it passes through the inclined feed pipe 1 and the conveying pipe 2 and then enters the discharge box 3. At the same time, when the bran moves towards the hot air blower 5, the hot air sprayed by the hot air blower 5 mixes with the bran to dry it. At the same time, when the hot air sprayed by the hot air blower 5 comes into contact with the bran, it can impact the bran and break up the clumps caused by static electricity and humidity.
[0031] Since the width of the discharge box 3 is greater than the diameter of the conveying pipe 2, when the bran enters the discharge box 3 through the conveying pipe 2, the airflow velocity carrying the bran decreases, the bran falls to the bottom of the discharge box 3 and is discharged through the induced feeder 41, and the gas carrying moisture after drying the bran is discharged through the Roots blower 42.
[0032] After the bran is dried, the hot air blower 5 and the Roots blower 42 are turned off, and the cleaning motor 61 is turned on. The cleaning motor 61 can drive the rotating rod 62 to rotate, which in turn drives the striking block 65 to rotate. When the striking block 65 rotates into the slide groove 67, it continues to rotate, and drives the slide groove 67 and the slider 68 to move towards the limit block 64. At the same time, the spring 66 is compressed. When the slider 68 rotates to disengage from the slide groove 67, the spring 66 drives the striking block 65 to reset. The striking block 65 strikes the conveying pipe 2, causing the bran attached to the inner wall of the conveying pipe 2 to fall down, so as to avoid the bran from deteriorating and affecting the quality of the dried bran in subsequent use. The bran attached to the inner wall of the conveying pipe 2 falls to the bottom of the conveying pipe 2 after the cleaning component 6 strikes the conveying pipe 2. At this time, the drain valve 8 is opened to discharge the bran that has fallen to the bottom of the conveying pipe 2 from the conveying pipe 2.
[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
