Description

Technical Field

[0001] This invention belongs to the field of dryer technology, and specifically relates to a multi-layer mesh belt dryer that is compatible with multiple materials. Background Technology

[0002] In the processing of materials such as grains and medicinal herbs, drying is a common practice to remove excess moisture and prevent mold and pests. However, the drying process often results in uneven moisture distribution within the material, leaving it with a relatively high internal moisture content. Therefore, after drying, the material undergoes a tempering process. This involves pausing the drying process after a certain point, maintaining a constant temperature, and allowing the internal moisture to gradually diffuse outwards, thus reducing the moisture gradient between the inside and outside of the material.

[0003] However, different types of materials have different requirements for drying and tempering due to differences in their composition, structure, and moisture content. Current dryers often use fixed drying programs, which are not convenient for repeated alternating drying and tempering operations, resulting in poor drying effects. Summary of the Invention

[0004] This invention provides a multi-material compatible multi-layer mesh belt dryer to solve the technical problem that current dryers are not convenient for repeated alternating drying and tempering operations, which leads to a reduction in the drying effect of materials.

[0005] This invention is achieved through the following technical solution: a multi-material compatible multi-layer mesh belt dryer, comprising a machine body, a mesh belt, and a heater, wherein the machine body is provided with multiple drying zones and multiple tempering zones, the drying zones and the tempering zones being spaced apart along a first direction; the mesh belt is installed in the machine body, the mesh belt extending along the first direction, the mesh belt being used to drive the material to move along the first direction, and to drive the material to alternately pass through the drying zones and the tempering zones in sequence; the heater is installed below the mesh belt and located within the drying zone, so as to dry the material on the mesh belt by heating, and the heater corresponds one-to-one with the drying zone.

[0006] Optionally, there are multiple mesh belts, which are evenly distributed along a second direction, which is perpendicular to the first direction. The multiple mesh belts are arranged in parallel, and the drying zone and the tempering zone extend along the second direction.

[0007] Optionally, it also includes an air intake fan, which is installed below the heater to deliver air heated by the heater into the drying zone.

[0008] Optionally, it also includes a partition installed inside the machine body and surrounding the drying zone to separate the drying zone from the tempering zone.

[0009] Optionally, it also includes a heat recovery unit, one end of which is connected to the top of the drying zone, and the other end of which is connected to the air intake fan, so as to recover and reuse the hot air above the drying zone.

[0010] Optionally, it also includes a fan hood, which is positioned over the top of the drying zone.

[0011] Optionally, it also includes a dehumidifier installed between the shroud and the heat recovery unit to dehumidify the recovered hot air.

[0012] Optionally, a filter is also included, installed between the shroud and the heat recovery unit, to remove impurities from the recovered hot air.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] This invention provides a multi-material compatible multi-layer mesh belt dryer, comprising a machine body, a mesh belt, and a heater. The machine body is provided with multiple drying zones and multiple tempering zones, which are spaced apart along a first direction. The mesh belt is installed in the machine body and extends along the first direction. The mesh belt is used to drive the material to move along the first direction and to drive the material to alternately pass through the drying zones and tempering zones in sequence. The heater is installed below the mesh belt and located in the drying zone to dry the material on the mesh belt by heating. The heater corresponds to each drying zone.

[0015] Through the above structure, the multi-material compatible multi-layer mesh belt dryer provided by this invention, when drying materials, places the materials to be dried on the mesh belt inside the machine body. Then, the mesh belt moves the materials to be dried. When the mesh belt enters the drying zone, the heater heats the dryer to dry the materials in the drying zone, reducing the moisture content of the materials. As the mesh belt continues to move, it continues to carry the materials into the tempering zone for tempering. Similarly, the mesh belt sequentially carries the materials through multiple drying zones and tempering zones alternately to perform multiple drying and tempering processes on the materials. By using different numbers of drying zones and tempering zones, it is convenient to dry and temper various materials. Therefore, this multi-material compatible multi-layer mesh belt dryer improves the drying effect of materials by carrying the materials through multiple drying zones and tempering zones alternately by the mesh belt, and is easy to use.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0024] This invention provides a multi-material compatible multi-layer mesh belt dryer, solving the technical problem that current dryers are inconvenient for repeated alternating drying and tempering operations, leading to reduced drying efficiency. This multi-material compatible multi-layer mesh belt dryer includes a machine body, a mesh belt 1, and a heater 2, wherein:

[0025] The machine body is equipped with multiple drying zones 9 and tempering zones 10. Drying zones 9 are used to dry the material to be dried, and tempering zones 10 are used to temper the dried material. The drying time and tempering time can be adjusted according to different materials or the required degree of dryness. Drying zones 9 and tempering zones 10 are spaced apart along a first direction. Figure 1 As shown, the first direction is parallel to the x-axis.

[0026] The mesh belt 1 is installed inside the machine body and extends along the first direction. Specifically, the mesh belt 1 is a conveyor belt with through holes for air to pass through, so that hot air can move upward from below the mesh belt 1 through the through holes to dry the material on the mesh belt 1. It is worth noting that the size of the through holes is smaller than the size of the material to reduce the material from falling directly downward through the through holes. The mesh belt 1 is used to drive the material to move along the first direction so that the material alternately passes through the drying zone 9 and the tempering zone 10, thereby allowing the material to be dried and tempered alternately for better drying. Specifically, the drying time and tempering time can be adjusted according to different materials or the required degree of dryness of the material by adjusting the conveying speed of the mesh belt 1 or adjusting the length of the drying zone 9 and the tempering zone 10.

[0027] Heater 2 is installed below mesh belt 1 and is located in drying zone 9. Heater 2 is used to heat the air to dry the material above mesh belt 1. Heater 2 corresponds one-to-one with drying zone 9, so that the material temperature in each drying zone 9 is easier to control. Heater 2 can be heating wire, heating rod or other heating element that can provide heat. More preferably, the temperature of heater 2 can be adjusted so that different temperatures can be set according to different materials, so as to make the drying of a wider range of materials possible.

[0028] Through the above structure, the multi-material compatible multi-layer mesh belt dryer provided by this invention, when drying materials, places the materials to be dried on the mesh belt 1 inside the machine body. Then, the mesh belt 1 moves the materials to be dried. When the mesh belt 1 enters the drying zone 9, the heater 2 heats the dryer to dry the materials in the drying zone 9, reducing the moisture content of the materials. As the mesh belt 1 continues to move, it continues to move the materials into the tempering zone 10 for tempering. Similarly, the mesh belt 1 sequentially moves the materials alternately through multiple drying zones 9 and tempering zones 10 to perform multiple drying and tempering processes on the materials. By using different numbers of drying zones 9 and tempering zones 10, it is convenient to dry and temper various materials. Therefore, this multi-material compatible multi-layer mesh belt dryer, by having the mesh belt 1 sequentially move the materials through multiple drying zones 9 and tempering zones 10, improves the drying effect of the materials and is convenient to use.

[0029] An optional implementation of this embodiment is as follows: Multiple mesh belts 1 are provided, and the multiple mesh belts 1 are evenly distributed along the second direction, such as... Figure 1 As shown, the second direction is perpendicular to the first direction and is parallel to the y-axis. Multiple mesh belts 1 are arranged in parallel. The drying zone 9 and the tempering zone 10 extend along the second direction. The conveying directions of adjacent mesh belts 1 are opposite. After the material moves along the mesh belt 1 to one end of the mesh belt 1, it falls through the mesh belt 1 and passes through the mesh belts 1 arranged along the second direction in sequence. This allows multiple mesh belts 1 to move the material between the drying zone 9 and the tempering zone 10, thereby increasing the number of drying and tempering cycles for the material, and thus drying the material better.

[0030] An optional implementation of this embodiment is as follows: In order to better dry the material, the multi-material compatible multi-layer mesh belt dryer also includes an air inlet fan 3. The air inlet fan 3 is installed below the heater 2. After the heater 2 heats the air from the air inlet fan 3, the air inlet fan 3 delivers the heated air from the bottom to the top of the mesh belt 1, so that the hot air passes through the drying zone 9 of the mesh belt 1 distributed along the second direction in a better manner. The air inlet fan 3 and the heater 2 make the flow speed of the hot air faster, thereby better removing the moisture in the material and better drying the material.

[0031] An optional implementation of this embodiment is as follows: In order to reduce the amount of hot air entering the tempering zone 10, the multi-material compatible multi-layer mesh belt dryer also includes a partition 4. The partition 4 is installed inside the machine body and surrounds the drying zone 9. Each tempering zone 10 is surrounded by a partition 4. There is a channel for material to pass through between the partition 4 and the mesh belt 1 below. The partition 4 is used to block the hot air output by the air inlet fan 3 from entering the tempering zone 10, thereby reducing the impact of hot air on the material located in the tempering zone 10, so as to better temper the material located in the tempering zone 10. At the same time, through the partition 4, the hot air can move better in the second direction in the drying zone 9, thereby improving the drying effect on the material in the drying zone 9.

[0032] An optional implementation of this embodiment is as follows: In order to better utilize the hot air after drying, the multi-material photocompatible multi-layer mesh belt dryer also includes a heat recovery unit 5. One end of the heat recovery unit 5 is connected to the top of the drying zone 9. The hot air after drying the material moves upward along the direction of the second direction, and then the heat recovery unit 5 recovers the hot air after drying. The other end of the heat recovery unit 5 is connected to the air inlet fan 3. The hot air recovered by the heat recovery unit 5 is transported again to the bottom of the heater 2 by the air inlet fan 3. After being heated by the heater 2, the material in the drying zone 9 is dried again. The reuse of the hot air recovered by the heat recovery unit 5 can reduce the heating time and power of the heater 2, thereby making it easier for the air to reach the specified temperature and improving the drying efficiency of the material. At the same time, the heat recovery unit 5 can also draw in fresh air from the external environment and transport it to the heater 2 for heating by the air inlet fan 3.

[0033] An optional implementation of this embodiment is as follows: In order to facilitate the heat recovery unit 5 to recover hot air, the multi-material photocompatible multi-layer mesh belt dryer also includes a hood 6. The hood 6 is installed on the top of the dryer and is connected to the heat recovery unit 5. The hood 6 is funnel-shaped, with one end of the hood 6 being the opening section. The opening end of the hood 6 is close to the drying zone 9, thereby increasing the area so that hot air can more easily enter the hood 6. The heat recovery unit 5 is connected to the other end of the hood 6, so as to facilitate the recovery of the hot air gathered by the hood 6.

[0034] An optional implementation of this embodiment is as follows: In order to reduce the moisture content of the hot air recovered by the heat recovery unit 5, the multi-material multi-layer mesh belt dryer also includes a dehumidifier 7. The dehumidifier 7 is installed between the hood 6 and the heat recovery unit 5. When the heat recovery unit 5 recovers hot air, the hot air that has been used to dry the material first passes through the dehumidifier 7 to reduce the moisture in the hot air, and then is recycled by the heat recovery unit 5, thereby reducing the moisture when the hot air is reused for drying, and thus improving the drying effect on the material.

[0035] An optional implementation of this embodiment is as follows: In order to reduce impurities in the hot air recovered by the heat recovery unit 5, the multi-material multi-layer mesh belt dryer also includes a filter 8. The filter 8 is installed between the hood 6 and the heat recovery unit 5. The filter 8 is used to filter the hot air that has been used to dry the material, remove dust and other impurities in the air, and reduce the impact of impurities in the recovered hot air on the material when the hot air is reused.

[0036] With the above structure, the multi-material compatible multi-layer mesh belt dryer provided by the present invention, when drying materials, places the materials to be dried on the mesh belt 1 inside the machine body. Then, the mesh belt 1 moves the materials to be dried. When the mesh belt 1 enters the drying zone 9, the heater 2 heats the dryer to dry the materials in the drying zone 9, reducing the moisture content of the materials. The inlet fan 3 delivers the heated air from below the mesh belt 1 to above, so that the hot air passes through the drying zone 9 of the mesh belt 1 distributed along the second direction more effectively. The baffle 4 is used to prevent the hot air output by the inlet fan 3 from entering the tempering zone 10, thereby reducing the misalignment of the hot air. Due to the influence of the material in the tempering zone 10, as the mesh belt 1 continues to move, it continues to carry the material into the tempering zone 10 for tempering. Similarly, the mesh belt 1 sequentially carries the material through multiple drying zones 9 and tempering zones 10 alternately to perform multiple drying and tempering processes. By using different numbers of drying zones 9 and tempering zones 10, it is possible to dry and temper various materials. The dried hot air enters the air hood 6, then passes through the dehumidifier 7 to remove moisture, and the filter 8 to remove impurities. After being recovered by the heat recovery unit 5, it is sent back to the heater 2 by the inlet fan 3 before entering the drying zone 9 to dry the material again. Therefore, this multi-material compatible multi-layer mesh belt dryer improves the drying effect of materials by carrying the material through multiple drying zones 9 and tempering zones 10 alternately by the mesh belt 1, and is easy to use.

[0037] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
