Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the technical field of double-cone drying equipment, and more specifically, to a double-cone drying device for preventing caking. Background Technology
[0002] Double cone vacuum dryers are commonly used drying equipment in many industries such as chemical and food processing, and are widely used in the drying of wet products. Their working principle utilizes the rotation of two cones to achieve uniform heating and drying of wet products in a vacuum environment. However, in actual production, this equipment has some problems.
[0003] After each drying cycle, the internal temperature of the double cone is typically around 100℃. If wet products are immediately added for the next drying cycle at this temperature, they are very likely to stick to the hot walls of the double cone. Over time, these stuck-to-the-wall wet products will gradually accumulate, forming large lumps. These large lumps will not only affect product quality, reducing product uniformity and purity, but may also clog the discharge port, increasing cleaning difficulty and reducing production efficiency.
[0004] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content
[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a double-cone drying device for preventing agglomeration, which solves the technical problem in the prior art that wet products are very easy to stick to the wall after contacting the high temperature of the double-cone wall, and over time, these sticky wet products will gradually accumulate and form large pieces of material.
[0006] According to one aspect, at least one embodiment of this disclosure provides an anti-caking double-cone drying apparatus, comprising:
[0007] A base and a double-cone tank, wherein the double-cone tank is rotatably connected to one side of the base;
[0008] A drive tilting assembly is disposed between the base and the double-cone tank body;
[0009] A connecting seat and a temperature conversion assembly are provided. The connecting seat is fixed to the outer wall of the double cone tank and rotatably connected to the base. The temperature conversion assembly is disposed on the connecting seat and the double cone tank.
[0010] The temperature conversion component includes a heating shroud disposed on the outer wall of the double cone tank, a cooling shroud disposed around the inner surface of the double cone tank, a suction hole being provided inside the connecting seat, and a transmission groove being provided on the outer end face of the connecting seat.
[0011] As a further technical solution, a docking seat is provided on the side surface of the base, the docking seat is rotatably connected to the transmission groove, and a first annular groove and a second annular groove are respectively opened on the surface of the docking seat, and a communicating cavity is opened in both the first annular groove and the second annular groove.
[0012] As a further technical solution, the other end of the pair of communicating cavities is respectively connected to the heating shroud and the cooling shroud, and the surface of the connecting seat is provided with a pair of annular bosses, which are respectively slidably attached to the first annular groove and the second annular groove.
[0013] As a further technical solution, the surface of the connecting seat is respectively provided with a vacuum suction pipe, a water supply pipe and a hot air pipe. The vacuum suction pipe is connected to the suction hole. The hot air pipe is connected to the heating cover through the first annular groove and the connecting cavity. The water supply pipe is connected to the inside of the cooling cover through the second annular groove and the connecting cavity. The outer surface of the heating cover is provided with a drain pipe.
[0014] As a further technical solution, the drive tilting assembly includes a drive motor, which is mounted on one side of the base. Both the output end of the drive motor and the drive shaft of the double cone tank are provided with transmission gears, which mesh with each other.
[0015] As a further technical solution, a drive shaft is rotatably connected to one end of the double-cone tank. The drive shaft has a hollow structure and is connected to the suction hole. Several air holes are opened on the inner end face of the drive shaft.
[0016] As a further technical solution, a second motor is provided on the outside of the base, the output end of the second motor is connected to the transmission shaft, and both ends of the transmission shaft are provided with dispersing blades.
[0017] As a further technical solution, both ends of the drive shaft are provided with sealing plates, and the sealing plates are rotatably connected to the inner wall of the double cone tank in a sealed fit.
[0018] The beneficial effects of the embodiments disclosed herein are as follows:
[0019] 1. In this disclosure, the beneficial effect of the temperature conversion component is that the heating shroud and the cooling shroud respectively realize the heating and cooling functions. The first annular groove, the second annular groove, the connecting cavity and the corresponding pipe ensure the stable transmission of media such as hot air and cooling water. The suction hole, in conjunction with the vacuum suction pipe, meets the vacuum requirements during the drying process. This component effectively prevents wet products from sticking and clumping together when in contact with the high-temperature double conical wall, ensuring product quality and improving production efficiency.
[0020] 2. In this disclosure, the driving tilting component has significant advantages. The cooperation between the drive motor and the transmission gear enables the stable rotation of the double-cone tank, allowing the material to be fully dispersed and dried. The drive shaft is connected to the suction hole and air hole, facilitating the extraction of air to create a vacuum environment. The second motor drives the drive shaft and the dispersing blades to rotate, further dispersing the material and preventing agglomeration. This component improves the drying effect, reduces material agglomeration, and lowers the difficulty of cleaning. Attached Figure Description

[0034] like Figures 1-5 As shown, it illustrates a dual-cone drying apparatus for preventing caking in one embodiment of the present disclosure, comprising:
[0035] The base 1 and the double-cone tank 2 are rotatably connected to one side of the base;
[0036] A drive tilting assembly 5 is disposed between the base 1 and the double cone tank 2;
[0037] The connecting seat 3 and the temperature conversion component 4 are provided. The connecting seat 3 is fixed to the outer wall of the double cone tank 2 and is rotatably connected to the base 1. The temperature conversion component 4 is provided on the connecting seat 3 and the double cone tank 2.
[0038] The temperature conversion component 4 includes a heating shield 4-1, which is disposed on the outer wall of the double-cone tank 2. A cooling shield 4-2 is disposed around the inner surface of the double-cone tank 2. A suction hole 4-3 is provided in the connecting seat 3. A transmission groove 4-4 is provided on the outer end face of the connecting seat 3. A docking seat 4-5 is provided on the side surface of the base 1. The docking seat 4-5 is rotatably connected to the transmission groove 4-4. A first annular groove 4-6 and a second annular groove 4-7 are respectively provided on the surface of the connecting seat 3. A communicating cavity 4-8 is provided in both the first annular groove 4-6 and the second annular groove 4-7. The other end of a pair of communicating cavities 4-8 is respectively connected to the heating shield 4-1 and the cooling shield 4-2. The connecting seat 3 has a pair of annular protrusions 4-9 on its surface, which slide and fit in the first annular groove 4-6 and the second annular groove 4-7 respectively. The connecting seat 3 has a vacuum suction pipe 4-10, a water supply pipe 4-11 and a hot air pipe 4-12 on its surface. The vacuum suction pipe 4-10 is connected to the suction hole 4-3. The hot air pipe 4-12 is connected to the heating shield 4-1 through the first annular groove 4-6 and the connecting cavity 4-8. The water supply pipe 4-11 is connected to the interior of the cooling shield 4-2 through the second annular groove 4-7 and the connecting cavity 4-8. The heating shield 4-1 has a drain pipe 4-13 on its outer surface.
[0039] In some examples, during the operation of the double cone dryer, to achieve efficient heating, drying, and cooling of materials and avoid material sticking and clumping during subsequent feeding, a temperature conversion component 4 is designed. This component includes a heating baffle 4-1 set on the outer wall of the double cone tank 2 and a cooling baffle 4-2 around the inner surface, which respectively undertake the functions of heating and cooling. The suction hole 4-3 opened in the connecting seat 3 can be used with the vacuum suction pipe 4-10 to extract air or steam from the double cone tank 2 to meet the vacuum requirements during the drying process. The transmission groove 4-4 on the outer end face of the connecting seat 3 is rotatably connected to the docking seat 4-5 on the side surface of the base 1, so that the connecting seat 3 can rotate flexibly relative to the base 1, which facilitates the connection and layout of various pipelines. The first annular groove 4-6, the second annular groove 4-7 on the surface of the connecting seat 3 and the internal connecting cavity 4-8 constitute a medium transmission channel. The first annular groove 4-6 and the second annular groove 4-7 on the surface of the connecting seat 3 and the internal connecting cavity 4-8 constitute a medium transmission channel. The connecting cavity 4-8 within the second annular groove 4-7 is connected to the heating baffle 4-1 and the cooling baffle 4-2 respectively. The hot air pipe 4-12 on the surface of the connecting seat 3 is connected to the heating baffle 4-1 through the first annular groove 4-6 and the connecting cavity 4-8, which can deliver hot air to the heating baffle 4-1 to heat the inside of the double cone tank 2, thereby heating the material inside the tank. The water supply pipe 4-11 is connected to the inside of the cooling baffle 4-2 through the second annular groove 4-7 and the connecting cavity 4-8, which can deliver cooling water to the cooling baffle 4-2 to cool the tank. The drain pipe 4-13 at the bottom of the cooling baffle 4-2 can return the cooled water to the water tank in the workshop for reuse. A pair of annular protrusions 4-9 on the surface of the connecting seat 3 slide and fit into the first annular groove 4-6 and the second annular groove 4-7 respectively, ensuring the sealing between the connecting seat 3 and the annular groove and preventing media leakage.
[0040] like Figures 1-5 As shown in the figure, the driving and flipping assembly 5 in this embodiment includes a drive motor 5-1, which is installed on one side of the base 1. The output end of the drive motor 5-1 and the drive shaft 5-3 of the double cone tank 2 are both provided with drive gears 5-2, which mesh with each other. The drive shaft 5-3 is rotatably connected to one end of the double cone tank 2. The drive shaft 5-3 has a hollow structure and is connected to the suction hole 4-3. Several air holes 5-4 are opened on the inner end face of the drive shaft 5-3. A second motor 5-5 is provided on the outside of the base 1. The output end of the second motor 5-5 is connected to the drive shaft 5-3. Dispersing blades 5-6 are provided at both ends of the surface of the drive shaft 5-3.
[0041] In some examples, during the operation of the double-cone mixing tank, a drive tilting assembly 5 is designed to achieve the rotation of the double-cone tank 2 and the effective dispersion of the internal materials. This assembly includes a drive motor 5-1 mounted on one side of the base 1. Both the output end of the drive motor 5-1 and the drive shaft 5-3 of the double-cone tank 2 are equipped with transmission gears 5-2, which mesh with each other. This constitutes the drive structure for the rotation of the double-cone tank 2. When the drive motor 5-1 starts, the transmission gears 5-2 drive the double-cone tank 2 to rotate around the drive shaft 5-3, thereby ensuring that the materials inside the tank are fully dispersed and dried during rotation. The drive shaft 5-3 is rotatably connected to one end of the double-cone tank 2. The drive shaft 5-3 has a hollow structure and is connected to the suction hole 4-3 on the connecting seat 3. The inner end face of the drive shaft 5-3 is provided with several air holes 5-4. This design allows the material inside the tank to be sucked through the suction holes 4-3 and the hollow structure of the drive shaft 5-3 during the rotation of the double cone tank 2, so that the inside of the double cone tank 2 reaches a vacuum state. The second motor 5-5 is set on the outside of the base 1, and its output end is connected to the drive shaft 5-3. The second motor 5-5 can drive the drive shaft 5-3 to rotate. The rotation of the drive shaft 5-3 can further assist in the dispersing of the material and prevent clumping. Both ends of the surface of the drive shaft 5-3 are provided with dispersing blades 5-6. When the double cone tank 2 rotates, the dispersing blades 5-6 will rotate with it to disperse the material inside the tank. This helps to prevent the material from clumping and makes the material more evenly distributed in the tank, thereby improving the drying effect.
[0042] For example, such as Figure 5 As shown, both ends of the drive shaft 5-3 are provided with sealing plates 6, and the sealing plates 6 are rotatably connected to the inner wall of the double cone tank 2 in a sealed fit.
[0043] In some examples, the sealing effect can be increased by setting a sealing plate 6, without affecting the normal rotation of the double cone tank 2.
[0044] In actual use: First, put the material to be dried into the double cone tank 2, then start the drive motor 5-1, which drives the double cone tank 2 to rotate through the transmission gear 5-2. The hot air pipe 4-12 is connected to the heating equipment and the heating is turned on. The hot air enters the heating hood 4-1 through the first annular groove 4-6 and the connecting cavity 4-8 to heat and dry the wet product in the double cone tank 2. At the same time, the vacuum equipment is used to extract the air in the tank using the vacuum suction pipe 4-10 and the suction hole 4-3 to create a vacuum environment. After drying, the hot air pipe 4-12 is closed, the water supply pipe 4-11 is opened, and the double cone tank 2 is opened to release the material. The cooling water enters the cooling hood 4-2 through the second annular groove 4-7 and the connecting cavity 4-8 to cool the double cone tank 2. After cooling, the material can be put in again. During the drying process, the second motor 5-5 is kept running, which drives the transmission shaft 5-3 and the dispersing blade 5-6 to rotate, which can break up the material clumps.
[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
