Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically to a uniform and continuous drying equipment for materials. Background Technology

[0002] Traditional material drying methods often employ intermittent dryers or natural air drying. Natural air drying is inefficient and presents collection problems. Intermittent drying, which involves drying one portion of material before moving on to another, struggles to meet the demands of large-scale, continuous processing. Furthermore, materials in existing drying equipment are often piled or stacked, leading to over-drying near the heat source and under-drying further away, resulting in uneven drying. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides a uniform and continuous drying device for materials, which overcomes the shortcomings of the prior art. It is reasonably designed and can effectively ensure the uniformity of material drying and ensure that the material can be dried uniformly and continuously. It effectively avoids the problem that the intermittent working mode of the prior art cannot meet the needs of large-scale and continuous processing.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A uniform and continuous drying device for materials includes a vertically arranged drying column. A hot air inlet is located at the lower end of the side of the drying column. A collecting pipe is installed along the vertical axis inside the drying column. The upper ends of the collecting pipe and the drying column are open. The lower end of the collecting pipe passes through the lower surface of the drying column and is connected to the inlet of a material conveying pipe via a discharge valve. An inner partition is installed above the inner cavity of the drying column, and the inner partition is sealed between the inner wall of the drying column and the outer wall of the collecting pipe. An inner feed port is located at the upper end of the side of the collecting pipe, and an outer feed port is located above the drying column. An inclined feed hopper is installed between the inner and outer feed ports.

[0006] The inner cavity of the collecting pipe is uniformly equipped with multiple guide slopes from top to bottom. The guide slopes are staggered on both sides of the inner wall of the collecting pipe, and the upper surface of the uppermost guide slope corresponds to the inner feed port. Multiple air holes are uniformly opened on the surface of the guide slopes. An air blowing frame is set directly below each guide slope. An air inlet is set on the side of the air blowing frame. The air inlet passes through the side surface of the collecting pipe and is connected to the inner cavity of the drying column. Multiple air blowing holes are opened on the upper surface of the air blowing frame.

[0007] Preferably, two rotating rods are vertically arranged on both sides of the inner cavity of the collecting pipe. The two rotating rods are located close to the side wall of the collecting pipe. The rotating rods pass through the respective guiding inclined surfaces located on both sides of the inner cavity of the collecting pipe. The upper end of the rotating rod is connected to the inner wall of the collecting pipe through a bearing seat. The lower end of the rotating rod extends out of the collecting pipe and is connected to the drive assembly. Multiple swinging plates are fixedly installed on the surface of each of the two rotating rods. The swinging plates are located on the upper surface of the corresponding guiding inclined surfaces.

[0008] Preferably, the drive assembly includes an electric telescopic rod and two sleeves. The electric telescopic rod is horizontally positioned on one side below the collecting pipe. The axial direction of the electric telescopic rod is parallel to the vertical line connecting the two rotating rods. The telescopic shaft of the electric telescopic rod is rotatably connected to one side of a hinge bracket via a rotating shaft. The other two ends of the hinge bracket are respectively connected to one end of the two transmission rods via rotating shafts. The two sleeves are fixedly fitted onto the outer surface of the lower end of the two rotating rods. A hinge seat is provided on the outer surface of each sleeve. The other ends of the two transmission rods are rotatably connected to the two hinge seats via rotating shafts.

[0009] Preferably, the lower surface of the guide slope is provided with a support crossbar, and the two ends of the support crossbar are respectively connected to the inner wall of the collecting pipe.

[0010] This invention provides a uniform and continuous drying device for materials. It offers the following advantages: During operation, materials fall sequentially onto various guide ramps, while hot air from the drying column enters each blowing frame through air inlets on the side. Air is then blown onto the guide ramps via air holes above the blowing frames, achieving a hot air drying effect on the surface of the materials on each guide ramp. By setting multiple staggered guide ramps, the materials are evenly dispersed as they fall, effectively ensuring uniformity during drying. Furthermore, the materials can be directly discharged through the discharge valve into the material conveying pipe, ensuring uniform and continuous drying. This effectively avoids the problem of intermittent operation in existing technologies, which cannot meet the needs of large-scale, continuous processing. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0019] Example 1, as Figure 1-4 As shown, a uniform and continuous drying device for materials includes a vertically arranged drying column 1, a hot air inlet 2 at the lower end of the side of the drying column 1, a collecting pipe 3 installed in the inner cavity of the drying column 1 along the vertical axis, the upper end of the collecting pipe 3 and the drying column 1 being open, the lower end of the collecting pipe 3 passing through the lower surface of the drying column 1 and connected to the inlet of the material conveying pipe 4 through a discharge valve, an inner partition 20 installed above the inner cavity of the drying column 1, the inner partition 20 being sealed between the inner wall of the drying column 1 and the outer wall of the collecting pipe 3; an inner feed port 5 is opened at the upper end of the side of the collecting pipe 3, an outer feed port 6 is opened above the drying column 1, and an inclined feed hopper 7 is installed between the inner feed port 5 and the outer feed port 6;

[0020] Multiple guide slopes 8 are evenly installed from top to bottom in the inner cavity of the collecting pipe 3. The guide slopes 8 are staggered on both sides of the inner wall of the collecting pipe 3. The upper surface of the uppermost guide slope 8 corresponds to the inner feed port 5. Multiple air holes are evenly opened on the surface of the guide slope 8. An air blowing frame 9 is set directly below each guide slope 8. An air inlet 10 is set on the side of the air blowing frame 9. The air inlet 10 passes through the side surface of the collecting pipe 3 and is connected to the inner cavity of the drying column 1. Multiple air blowing holes 11 are opened on the upper surface of the air blowing frame 9.

[0021] Working principle:

[0022] Before use, connect the hot air inlet 2 at the lower side of the drying column 1 to the output end of the hot air blower so that the hot air blower can deliver continuous hot air into the inner cavity of the drying column 1.

[0023] During operation, the material is fed into the outer feed port 6 and then guided into the collecting pipe 3 through the inclined feed hopper 7 from the inner feed port 5. After entering the inner cavity of the collecting pipe 3, the material falls sequentially onto each guide inclined surface 8. The material slides down in an S-shaped path through the staggered guide inclined surfaces 8. Since each guide inclined surface 8 is equipped with an air blowing frame 9, and the air blowing frame 9 is connected to the inner cavity of the drying column 1 through the side air inlet 10, the hot air in the inner cavity of the drying column 1 can enter each air blowing frame 9 through the side air inlet 10. Therefore, each time the material falls onto a guide inclined surface 8, air can be blown onto the guide inclined surface 8 through the air blowing hole 11 above the air blowing frame 9. The material on the upper surface of each guide inclined surface 8 is dried by hot air blowing through the multiple air holes on the surface of the guide inclined surface 8. The hot air carrying water vapor is output through the upper opening of the collecting pipe 3 and the drying column 1.

[0024] In this invention, by setting multiple staggered guide ramps 8, the material can be evenly dispersed as it falls onto each guide ramp 8, thus effectively ensuring the uniformity of material drying. After passing through each guide ramp 8, the material can be directly discharged into the material conveying pipe 4 through the discharge valve, thus ensuring that the material can be dried evenly and continuously. This effectively avoids the problem of intermittent working mode in the prior art, which cannot meet the needs of large-scale, continuous processing.

[0025] In Example 2, as a further preferred embodiment of Example 1, two rotating rods 12 are vertically arranged on both sides of the inner cavity of the collecting pipe 3. The two rotating rods 12 are located close to the side wall of the collecting pipe 3. The rotating rods 12 pass through the respective guiding inclined surfaces 8 located on both sides of the inner cavity of the collecting pipe 3. The upper end of the rotating rod 12 is connected to the inner wall of the collecting pipe 3 through the bearing seat 21, and the lower end of the rotating rod 12 passes through the collecting pipe 3 and is connected to the drive assembly. Multiple swing hanging plates 18 are fixedly installed on the surface of the two rotating rods 12. The swing hanging plates 18 are respectively located on the upper surface of the corresponding guiding inclined surfaces 8.

[0026] Therefore, during use, the drive assembly can be used to drive the rotating rod 12 to rotate back and forth within a certain angle, thereby causing the swinging hanging plate 18 on the surface of the rotating rod 12 to swing back and forth around the rotating rod. Since the swinging hanging plate 18 is attached to the upper surface of each guide slope 8, the material on the upper surface of the guide slope 8 can be scraped off by the swinging hanging plate 18 swinging back and forth on the upper surface of each guide slope 8, thus preventing the material from staying on the guide slope 8 for a long time.

[0027] In embodiment three, as a further preferred embodiment two, the drive assembly includes an electric telescopic rod 13 and two sleeves 14. The electric telescopic rod 13 is horizontally arranged on one side below the collecting pipe 3. The axial direction of the electric telescopic rod 13 is parallel to the vertical line connecting the two rotating rods 12. The telescopic shaft of the electric telescopic rod 13 is rotatably connected to one side of the hinge bracket 15 through a rotating shaft. The other two ends of the hinge bracket 15 are respectively connected to one end of the two transmission rods 16 through a rotating shaft. The two sleeves 14 are respectively fixedly sleeved on the lower outer surface of the two rotating rods 12. The outer surface of each sleeve 14 is provided with a hinge seat 17. The other ends of the two transmission rods 16 are respectively rotatably connected to the two hinge seats 17 through a rotating shaft.

[0028] Therefore, when the rotating rod 12 is driven to rotate back and forth within a certain angle by the drive assembly, the telescopic shaft of the electric telescopic rod 13 is controlled to move back and forth, thereby driving the hinge bracket 15 to move in the left and right directions. Since the two ends of the hinge bracket 15 are respectively connected to the hinge seats 17 on the outer surface of the two sleeves 14 through two transmission rods 16, the movement of the hinge bracket 15 can drive the two sleeves 14 to rotate back and forth, thereby driving the rotating rod 12 to rotate back and forth, thereby driving the swing hanging plate 18 on the outer surface of the rotating rod 12 to swing back and forth on the upper surface of each guide slope 8.

[0029] In Example 4, as a further preferred embodiment of Example 1, a support crossbar 19 is provided on the lower surface of the guide slope 8, with both ends of the support crossbar 19 connected to the inner wall of the collecting pipe 3. The support crossbar 19 effectively supports the guide slope 8.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
