Abstract
Description
Technical Field
[0001] The present application relates to the field of material drying, and in particular to a drying device. Background Art
[0002] During the drying process of a conventional rotary drying furnace, gas is continuously introduced into the drying furnace, and a large amount of dust will be carried to the discharge section along with the airflow and water vapor. On the one hand, some of the dust will be carried out of the heating section of the furnace body along with the airflow. At the same time, if the dust and water vapor settle in the discharge section together, when the drying is completed and the material is discharged, the undried material settled in the discharge section will contaminate the dried qualified material. Utility Model Content
[0003] The purpose of this application is to provide a drying device to improve the problem of contamination of dried materials.
[0004] The embodiment of the present application is implemented as follows:
[0005] In the first aspect, an embodiment of the present application provides a drying device, comprising a frame and a furnace body rotatably arranged on the frame; along the rotation axis direction of the furnace body, the furnace body has a feeding section, a drying section and a discharging section connected in sequence; a part of the discharging section close to the drying section is provided with a discharging section furnace plug, and a first heating device is provided on the outside of the discharging section, the first heating device is located on the side of the discharging section furnace plug away from the drying section, and the first heating device is used to heat the discharging section.
[0006] In the above technical solution, the furnace plug can serve to isolate the material and a large amount of dust from drying in the drying section. After the drying process is completed, the discharge section furnace plug is removed, and the dried material is then removed. Because a first heating device is provided on the side of the discharge section furnace plug away from the drying section, located outside the discharge section, the discharge section can be heated by the first heating device during the drying process, thereby improving the condensation of water vapor in the discharge section. This prevents dust from passing through the discharge section furnace plug from adhering to the discharge section, thereby reducing contamination of the dried material.
[0007] In some optional embodiments, the first heating device is fixed to the frame and arranged along the circumference of the discharging section, and the distance between the first heating device and the discharging section is not greater than 10 mm.
[0008] In the above technical solution, the first heating device is fixed to the frame, which does not rotate with the furnace body. Therefore, the wiring connected to the first heating device does not become entangled. When the distance between the first heating device and the discharge section is no more than 10 mm, the first heating device has a good heating effect on the discharge section.
[0009] In some optional embodiments, the furnace body has a discharge port located in the discharge section; the discharge section furnace plug is provided with a first axially penetrating through hole, the first through hole connecting the discharge port with the cavity inside the drying section; a filtering device is provided in the first through hole.
[0010] In the above technical solution, the water vapor and dust in the furnace body need to pass through the first through hole before they can move to the side where the discharge port is located. By arranging a filtering device in the first through hole, the dust entering the first through hole can be blocked to reduce the dust attached to the discharge section after passing through the furnace blockage of the discharge section, thereby reducing the pollution to the dried material.
[0011] In some optional embodiments, the filtering surface of the filtering device protrudes toward one side of the drying section.
[0012] In the above technical solution, since the filtering surface of the filtering device protrudes toward the side where the drying section is located, the filtering surface has a larger surface area, which can better contact with the dust and achieve dust blocking. On the one hand, the dust can be kept in the drying section to be dried, and on the other hand, the dust that passes through the first through hole and reaches the side of the discharge section away from the drying section can be reduced, thereby reducing the pollution to the dried material.
[0013] In some optional embodiments, the hole wall of the first through hole is provided with a chamfer, and the chamfer is located on the side of the filtering surface facing the drying section.
[0014] In the above technical solution, the dust blocked by the filtering surface will fall on the chamfer of the wall of the first through hole. It is not difficult to understand that the chamfer is located on an inclined surface, and the dust falling on the chamfer can more easily fall into the cavity of the drying section of the furnace body.
[0015] In some optional embodiments, the filtering device includes a first filter element, which protrudes toward one side of the drying section to form the filtering surface. A plurality of sedimentation channels are provided in the first filter element, and the sedimentation channels are connected one-to-one with the filter holes of the filtering surface. The end of the sedimentation channel facing away from the filter hole is connected to the back-blowing tank, and the outer periphery of the first filter element is connected to the inner wall of the first through hole.
[0016] In the above technical solution, the outer periphery of the first filter element is connected to the inner wall of the first through-hole, making it virtually impossible for dust to pass through the filter device and the inner wall of the first through-hole. Dust primarily enters the deposition channel through the filter holes of the first filter element, where a large amount of dust accumulates, with only a small amount exiting the deposition channel at the end away from the drying section. Because the end of the deposition channel facing away from the filter holes is connected to the backflush pipe, air is blown into the deposition channel through the backflush tank, allowing dust deposited in the deposition channel to be blown back into the drying section of the furnace for drying, thereby reducing material waste.
[0017] In some optional embodiments, the filtering device also includes a filter screen, which is arranged at the end of the first filter element facing away from the drying section, and a deposition chamber is formed between the filter screen and the first filter element, and the deposition chamber is connected to the deposition channel; the deposition chamber is connected to a first pipe, and the end of the first pipe away from the deposition chamber is selectively connected to the back-blowing tank or the dust collector.
[0018] In the above technical solution, the deposition chamber formed between the filter screen and the first filter element collects dust that escapes from the end of the deposition channel away from the drying section, thereby reducing the risk of leakage of this undried dust and contamination of the dried material. A dust collector connected via the first pipe centrally collects dust within the deposition chamber, and a backflush tank connected via the first pipe blows dust deposited in the deposition channel back into the drying section of the furnace for drying.
[0019] In some optional embodiments, the filter screen is a conical screen, the smaller end of the conical screen is located on a side away from the drying section, and the first pipe is connected to the smaller end of the conical screen.
[0020] In the above technical solution, since the filter is a conical mesh, it can better collect dust, and the filter has a smaller end, which can be easily connected to the first pipe.
[0021] In some optional embodiments, the feed section of the furnace body is connected to an air inlet tank; the discharge port is provided with a furnace tail sealing door, and the furnace tail sealing door is provided with a second through hole for the first pipe to pass through, and the size of the second through hole is larger than the outer diameter of the first pipe, so that there is a gap between the furnace tail sealing door and the first pipe.
[0022] In the above technical solution, gas can be continuously introduced into the furnace body through the gas inlet tank. Since the size of the second through hole is larger than the outer diameter of the first pipe, the gas in the furnace body can be discharged through the gap between the furnace tail sealing door and the first pipe to avoid excessive pressure in the furnace body.
[0023] In some optional embodiments, a second heating device is provided on the outside of the air inlet tank.
[0024] In the above technical solution, since the second heating device is provided on the outside of the gas inlet tank, the gas introduced into the furnace body has a certain temperature, which can improve the drying efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.
[0030] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without making any creative efforts shall fall within the scope of protection of the present application.
[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.
[0032] In the description of this application, it should be noted that the terms "center," "upper," "lower," "vertical," "horizontal," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of this application is typically placed when in use. These terms are intended solely to facilitate the description of this application and to simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0033] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.
[0034] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.
[0035] The present application provides a drying device, such as Figure 1 As shown, the furnace comprises a frame 39 and a furnace body 17 rotatably mounted on the frame 39. Along the rotation axis of the furnace body 17, the furnace body 17 can be divided into a feeding section, a drying section, and a discharging section. The feeding section is used to add material to the internal cavity of the furnace body 17. The drying section is where the material primarily resides during the drying process. After drying in the drying section, the material is removed from the discharging section.
[0036] Furthermore, a discharge section furnace plug 43 is provided within the furnace body 17, located in the section of the discharge section near the drying section. A first heating device 9 is also provided outside the discharge section to heat the section. In practice, the first heating device 9 maintains the temperature of the discharge section at approximately 120°C to prevent condensation of moisture there.
[0037] It is not difficult to understand that during the drying process of the material in the drying section, the furnace body 17 will rotate to achieve uniform heating of the material, and the moisture in the material will turn into water vapor after being heated. The water vapor will condense into liquid water after moving to a lower temperature area and cooling. During the rotation of the furnace body 17, the material will produce dust. Although the discharge section furnace plug 43 can play a role in hindering the formation to a certain extent, there will still be a situation where the dust moves to the position where the water vapor condenses, causing the dust to come into contact with the liquid water and adhere to the inner wall of the furnace body 17, and the dust cannot be fully dried at this position. If the temperature of the discharge section of the furnace body 17 is low, dust will adhere to the discharge section and will not be fully dried. During the process of drying the material in the drying section and taking it out, the incompletely dried material attached to the discharge section will mix with the completely dried material in the drying section, thereby contaminating the dried qualified material. Therefore, the method provided in the above embodiment of the present application of setting a first heating device 9 on the outside of the drying section to heat the discharge section can, on the one hand, reduce the condensation of water vapor in the discharge section, thereby reducing the material attached to the discharge section; on the other hand, it can heat the material attached to the discharge section so that this part of the material can also be completely dried.
[0038] In some embodiments of the present application, to better heat the discharge section, the spacing between the first heating device 9 and the discharge section is no greater than 10 mm, allowing the heat provided by the first heating device 9 to more effectively reach the discharge section. The spacing between the first heating device 9 and the discharge section can be 1 mm, 2 mm, 5 mm, or 10 mm, among others. The first heating device 9 is fixed to the frame 39 and arranged circumferentially along the discharge section, allowing the first heating device 9 to heat the entire discharge section, reducing heating blind spots. The first heating device 9 is fixed to the frame 39. If the first heating device 9 requires wiring, this prevents the first heating device 9 from rotating with the furnace body 17, thereby preventing the wiring connected to the first heating device 9 from becoming entangled. Furthermore, the rotation of the furnace body 17 relative to the first heating device 9 ensures more uniform heating of the furnace body 17. Furthermore, an insulation structure can be provided on the frame 39 to reduce heat loss from the first heating device 9.
[0039] In other embodiments of the present application, the first heating device 9 may be fixedly mounted on the frame 39. In this embodiment, the first heating device 9 may be connected to the circuit via a brush or other structure. In other embodiments, the first heating device 9 may be fixedly mounted outside the heating section, and the first heating devices 9 may be evenly arranged along the circumference of the heating section to achieve a better heating effect on the discharge section.
[0040] Furthermore, the furnace body 17 has a discharge port located in the discharge section; the discharge section furnace plug 43 is provided with a first through hole that runs circumferentially therethrough, and the first through hole connects the discharge port with the cavity inside the drying device, that is, the material generated during the rotation of the furnace body 17 can pass through the first through hole of the discharge section furnace plug 43 and then move toward the discharge port. A filter device 42 is provided in the first through hole, and the filter device 42 can play a filtering role. Due to the presence of the first through hole, a larger channel is provided for the flow of gas. Therefore, the water vapor generated during the drying process will pass through the first through hole and pass through the filter device 42. During the movement of the water vapor, the dust will also be carried along with it. When the dust passes through the first through hole, it will be blocked by the filter device 42, so that the dust will be retained in the cavity located in the drying section of the furnace body 17 for drying.
[0041] Among them, the filter device 42 blocks the dust on the one hand because the dust hits the surface of the filter device 42 and falls off instead of moving with the water vapor; on the other hand, the filtering function of the filter device 42 keeps the dust inside the filter device 42.
[0042] In some embodiments, in order to allow more dust to hit the surface of the filter device 42, the filter surface of the filter device 42 protrudes toward the side of the drying section. Among them, the filter surface of the filter device 42 is the surface facing the side where the drying section is located. Since the filter surface of the filter device 42 protrudes toward the side where the drying section is located, the filter surface has a larger surface area, thereby better contacting with the dust and achieving dust blocking. In the embodiment provided in the present application, the filter surface of the filter device 42 can be a spherical surface or other convex curved surface. Furthermore, the hole wall of the first through hole can also be provided with a chamfer, and the chamfer is located on the side of the filter surface facing the drying section, that is, as Figure 2 As shown, a chamfer is provided at one end of the first through hole facing the drying section, and the position of the chamfer is an inclined surface. The dust that hits the filtering surface and falls on the chamfer can fall into the cavity of the drying section of the furnace body 17 more easily.
[0043] In some embodiments, in order to enable the filtering function of the filter device 42 to retain more dust within the filter device 42, the filter device 42 includes a first filter element, the outer periphery of the first filter element is connected to the inner wall of the first through hole, so that there is almost no gap between the filter device 42 and the inner wall of the first through hole for dust to pass through. The first filter element protrudes toward the side of the drying section to form a filter surface; a plurality of deposition channels 422 are provided in the first filter element, and the deposition channels 422 correspond to the filter holes of the filter surface and are connected one by one, that is, the dust in the drying section can enter the deposition channels 422 through the filter holes of the filter surface. It is not difficult to understand that by controlling the length and size of the deposition channels 422, it is possible to achieve that the dust is deposited in the deposition channels 422 and no longer continues to move with the water vapor, thereby improving the movement of the dust to the location where the water vapor condenses and adheres to the location where the water vapor condenses. Furthermore, the end of the deposition channel 422 away from the filter hole is also connected to the back-blowing tank 1, which can fill gas into the deposition channel 422 and then blow the dust deposited in the deposition channel 422 out to the cavity in the drying section.
[0044] exist Figure 2 In the illustrated embodiment, the first filter element is formed by connecting a shell-like structure 421 and a plate-like structure. The filtering surface of the filter device 42 is located in the shell-like structure 421. One end of the sedimentation channel 422 is connected to the shell-like structure 421, and the other end is connected to the plate-like structure. In other embodiments, the first filter element may also adopt other structures.
[0045] Furthermore, the filter device 42 further includes a filter screen 423, which is disposed at one end of the first filter element away from the drying section and forms a sedimentation chamber with the first filter element. The sedimentation chamber is connected to the sedimentation channel 422 so that dust flowing out of the sedimentation channel 422 enters the sedimentation chamber. Figure 2 In the illustrated embodiment, the filter screen 423 and the plate-like structure in the first filter element enclose a sedimentation chamber.
[0046] It is not difficult to understand that in the process of dust moving with water vapor, after passing through the filter surface of the filter device 42 and the deposition channel 422 in sequence, only a small amount of dust can reach the deposition chamber; the deposition chamber plays a role in collecting dust. Furthermore, the filter screen 423 is connected to the first pipe 44, one end of the first pipe 44 is connected to the deposition chamber, and the other end is selectively connected to the back-blowing tank 1 or the dust collector 50. It is not difficult to understand that when the end of the first pipe 44 away from the deposition chamber is connected to the back-blowing tank 1, the gas blown out by the back-blowing tank 1 passes through the first pipe 44 and the deposition chamber in sequence and enters the deposition channel 422, and then blows the dust deposited in the deposition channel 422 into the cavity of the furnace body 17 located in the drying section; when the end of the first pipe 44 away from the deposition chamber is connected to the dust collector 50, the dust in the deposition chamber can be sucked into the dust collector 50. It is readily understood that the filter 423 should have a plurality of fine pores. This effectively prevents the pores of the filter 423 from being clogged by dust from the deposition chamber by promptly collecting dust from the deposition chamber into the dust collector 50. The pores of the filter 423 allow water vapor to pass through, thereby preventing excessive gas pressure within the drying section and within the filter device 42.
[0047] In some embodiments, the filter mesh 423 is a conical mesh, that is, the filter mesh 423 has a smaller end and a larger end. Figure 2 As shown, the smaller end of the conical net is located at a side away from the drying section, and the first pipe 44 is connected to the smaller end of the conical net. Since the first pipe 44 is connected to the smaller end of the conical net, the diameter of the first pipe 44 can be smaller.
[0048] In some embodiments, the feed section of the furnace body 17 is connected to an air inlet tank 33. During the drying process of the material, air can be inflated into the furnace body 17 through the air inlet tank 33. A furnace tail sealing door 8 is provided at the discharge port of the furnace body 17. The furnace tail sealing door 8 is provided with a second through hole for the first pipe 44 to pass through, and the size of the second through hole is larger than the outer diameter of the first pipe 44, so that there is a gap between the furnace tail sealing door 8 and the first pipe 44. The gas in the furnace body 17 can be discharged through the gap to avoid excessive pressure in the furnace body 17. Furthermore, a second heating device can be provided on the outside of the air inlet tank 33. By heating the air inlet tank 33 with the second heating device, the gas filled into the furnace body 17 can have a certain temperature. In particular, for materials that need to be dried at low temperatures (200°C-300°C), the drying efficiency can be effectively improved.
