Description

Technical Field

[0001] The invention relates to the technical field of cellulose processing, and in particular to a multifunctional cellulose material crushing and drying comprehensive processing process and a system thereof. Background Art

[0002] During the production and processing of cellulose materials, the auger is used to push the airflow for drying. The materials are first dried in a drying tower, then separated by a cyclone separator, and finally fall into a grinder for crushing. The materials that are not completely crushed after crushing will return to the grinder for re-crushing.

[0003] The prior art still has the following deficiencies when processing cellulose materials:

[0004] 1. In the prior art, the material is dried and then crushed, resulting in low crushing fineness and excessively large particle size of the later material, which in turn affects the preparation quality of subsequent materials.

[0005] 2. In addition, the material can only be dried once during the drying process. When the material particles are large, in order to achieve the purpose of drying, it is necessary to inject higher hot air and dry it for a long time. This not only causes the hot air to easily escape to the outside, resulting in high heat loss and energy consumption, but also the high hot air temperature is easy to damage the equipment. In addition, it is difficult to accurately control the moisture content of the material in a single drying.

[0006] In view of the above problems, the present invention document proposes a multifunctional cellulose material crushing and drying comprehensive processing process and system. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0052] Example 1: Reference Figure 1 and Figure 2 The multifunctional crushing and drying comprehensive processing system comprises a first processing device 1, a second processing device 50 and a conveying cylinder 2 located between the first processing device 1 and the second processing device 50. The first processing device 1 and the second processing device 50 have the same structure and both have the function of crushing and drying materials. The conveying cylinder 2 is used to transfer the crushed and dried materials in the first processing device 1 to the second processing device 50 for secondary crushing and drying.

[0053] Reference Figure 2 The first processing equipment 1 is mainly composed of a crushing box 3, a heating furnace 4, a screening box 20, an exhaust fan 5 and a drying tower 6. The crushing box 3 is fixed on the top of the heating furnace 4, and the two are connected through multiple air inlets 17. Multiple first heating plates 19 are installed in the heating furnace 4, and these heating plates can discharge the heated air into the crushing box 3 through the air inlet 17, so as to dry the material. A stirring shaft 7 is rotatably connected in the crushing box 3, and the top end of the stirring shaft 7 extends to the top of the crushing box 3 for crushing the material. The drying tower 6 is fixedly connected to one side of the crushing box 3 through a horizontal plate.

[0054] Reference Figure 2 The screening box 20 is fixedly arranged on the top of the crushing box 3, and its function is to screen the crushed materials in the crushing box 3. The air inlet and the air outlet of the exhaust fan 5 are respectively connected to the screening box 20 and the drying tower 6 through a hose. The working mechanism of the exhaust fan 5 is to suck the screened materials in the screening box 20 and transport them to the drying tower 6 for further drying.

[0055] Reference Figure 2-Figure 5 In the crushing box 3, a crushing structure is provided for crushing and drying the materials entering the crushing box 3. The crushing structure is composed of a plurality of grinding mechanisms 10, which are arranged in sequence from top to bottom and fixed on the outer wall of the stirring shaft 7. Each grinding mechanism 10 is composed of two clamping plates 11, and a plurality of grinding wheels 12 are rotatably connected between the clamping plates 11. A fixed cylinder 13 is fixed on the top of the crushing box 3, and all the grinding mechanisms 10 are located in this fixed cylinder 13. The inner wall of the fixed cylinder 13 is provided with a plurality of annular grinding grooves 14 corresponding to the grinding mechanisms 10, and these annular grinding grooves 14 cooperate with the grinding wheels 12 to complete the crushing of the materials. A return trough 15 is formed between the crushing box 3 and the fixed cylinder 13 for collecting the crushed materials. A feed pipe 21 is fixed on the top inner wall of the return trough 15, and the top end of the feed pipe 21 extends into the screening box 20, which is used to discharge the crushed materials into the screening box 20.

[0056] Reference Figure 2 and Figure 3 In addition, a guide ring 18 is fixed to the inner wall of the bottom of the crushing box 3, and its top diameter is smaller than the bottom diameter, which is used to guide the crushed material into the return trough 15. When the material enters the crushing box 3, the stirring shaft 7 and the grinding mechanism 10 are driven by the motor to rotate. Under the centrifugal force of the grinding mechanism 10, the material is pushed outward, and the stirring shaft 7 drives the clamping plate 11 and the grinding wheel 12 to rotate.

The bottom end of the lifting rod 30 is sealed and slidably extended into the crushing box 3. A fixed plate 27 is fixed to the inner wall of one side of the fixed cylinder 13, and a trapezoidal block 29 is fixed to one side of the lifting rod 30.

A material leakage hole 25 is provided in the moving plate 24, which cooperates with the material guide pipe 23 to intermittently discharge the material with a large particle size into the crushing box 3 for crushing.

[0059] Specifically, when the exhaust fan 5 is working, it draws the air and crushed materials in the return trough 15 into the screening box 20 through the screening box 20 and the feed pipe 21. After the material falls on the screen plate 22, the stirring shaft 7 drives the protrusion 26 to rotate. The protrusion 26 pushes the movable plate 24 to move outward, and the movable plate 24 squeezes the lifting rod 30 downward through the trapezoidal block 29. Under the cooperation of the protrusion 26 and the first spring 28, the lifting rod 30 can be controlled to move up and down, thereby knocking the screen plate 22 and screening the materials on the screen plate 22. The materials with small particle size fall on the bottom inner wall of the screening box 20, while the materials with large particle size fall into the guide pipe 23 along the screen plate 22. When the leakage hole 25 is aligned with the guide pipe 23, the material re-enters the top of the grinding mechanism 10 for another crushing, thereby ensuring the particle size of the material.

The rotating shaft 31 passes through these material spreading and drying components to achieve the flattening and conveying of the materials.

[0061] Reference Figure 8 The specific structure of the material spreading and drying component includes an annular inner concave plate 32 and an annular convex plate 33. The annular inner concave plate 32 is fixed in the drying tower 6, and the outer wall of the annular convex plate 33 is fixed in the drying tower 6 by a plurality of fixing rods 36, and the annular convex plate 33 is located in the annular inner concave plate 32. Above the annular inner concave plate 32 and the annular convex plate 33, a first material spreading plate 34 and a second material spreading plate 35 are respectively provided. One end of the first material spreading plate 34 and the second material spreading plate 35 are both fixed to the outer wall of the rotating shaft 31.

[0062] Specifically, when the rotating shaft 31 rotates, the first material spreading plate 34 and the second material spreading plate 35 are driven to rotate together. This design is used to spread the material on the annular inner concave plate 32 and the annular convex plate 33 to improve the drying efficiency.

[0063] Reference Figure 8 and Fig. 9 In order to realize the step-by-step downward discharge of materials, a plurality of knocking structures are also provided in the drying tower 6, and these knocking structures cooperate with the material spreading and drying components. The specific implementation of the knocking structure includes a plurality of slide bars 37, and these slide bars 37 all slide through the corresponding fixed rods 36. A first knocking ball 38 located below the annular inner concave plate 32 is fixed to the top of the slide bar 37, which is used to knock the annular inner concave plate 32. At the same time, the outer wall of the slide bar 37 is also fixedly sleeved with a second knocking ball 40 located below the annular convex plate 33, which is used to knock the annular convex plate 33. In order to drive the slide bar 37 to move up and reset, the outer wall of the slide bar 37 is sleeved with a second spring 41 fixed on the top of the second knocking ball 40, and the top of the second spring 41 is fixedly connected to the bottom of the fixed rod 36.

[0064] Reference Figure 8 and Fig. 9 In addition, an arc block 39 is fixed to the outer wall of the slide bar 37. The arc block 39 cooperates with the second spreading plate 35 to drive the slide bar 37 to move downward when the second spreading plate 35 rotates.

[0065] Specifically, when the rotating shaft 31 drives the first spreading plate 34 and the second spreading plate 35 to rotate, the first spreading plate 34 can spread the material on the annular inner concave plate 32, and the second spreading plate 35 can not only spread the material on the annular convex plate 33 when rotating, but also drive the first knocking ball 38 and the second knocking ball 40 to move up and down through the cooperation of the arc block 39 and the slide rod 37, thereby knocking the annular inner concave plate 32 and the annular convex plate 33. This knocking action can transport the material on the annular inner concave plate 32 and the annular convex plate 33 downward, so that the material is flattened and dried for multiple times, thereby improving the drying efficiency.

[0066] Reference Figure 7 and Figure 8In order to further improve the drying efficiency, a plurality of second heating plates are fixed to the inner wall of the drying tower 6. These second heating plates are used to heat the annular inner concave plate 32 and the annular convex plate 33, so as to facilitate drying the materials spread on the annular inner concave plate 32 and the annular convex plate 33. At the same time, circular holes are provided in the annular inner concave plate 32 and the annular convex plate 33. The inner diameter of the circular hole in the annular inner concave plate 32 is larger than the diameter of the rotating shaft 31. This design is to enable the materials to fall smoothly on the annular convex plate 33. The inner diameter of the circular hole in the annular convex plate 33 is the same as the inner diameter of the rotating shaft 31, so that the materials can be prevented from falling through the circular hole in the annular convex plate 33, ensuring the stable spreading and drying of the materials on the spreading and drying components.

[0067] Reference Figure 2 and Figure 3 A threaded rotating ring 16 is fixedly installed inside the return trough 15 of the pulverizer. The threaded rotating ring 16 has a special connection method: its inner wall is closely connected to the outer wall of the fixed cylinder 13, and the outer wall is fixedly connected to the inner wall of the crushing box 3. This design not only stabilizes the overall structure, but more importantly, the special shape of the threaded rotating ring 16 can increase the contact time between the crushed material and the hot air in the return trough 15. This design is intended to extend the drying time of the material and ensure that the material can be fully dried.

[0068] Reference Figure 2 and Figure 7 Furthermore, a return air duct 8 is fixedly connected to the bottom of one side of the drying tower 6. One end of the return air duct 8 extends to the inside of the stirring shaft 7 by rotating or sliding. A plurality of ventilation holes 9 are provided inside the stirring shaft 7. When the hot air in the drying tower 6 enters the stirring shaft 7 through the return air duct 8, the ventilation holes 9 allow the hot air to flow out, thereby using the residual heat in the drying tower 6 to preheat the material above the grinding mechanism 10. Such a preheating step helps to improve the efficiency of subsequent crushing and drying.

[0069] Reference Figure 2 A first material pipe 47 is installed on the top of one side of the conveying cylinder 2, and the first material pipe 47 is connected to the bottom of the drying tower 6. A second material pipe 48 is installed on the bottom of the other side of the conveying cylinder 2, and the second material pipe 48 is connected to the crushing box 3 in the second processing equipment 50. An auger 46 is set inside the conveying cylinder 2. The function of the auger 46 is to suck the material dried in the drying tower 6 in the first processing equipment 1 into the conveying cylinder 2 through the first material pipe 47, and then transport the material to the second material pipe 48 through the rotation of the auger 46, and finally transport it to the crushing box 3 of the second processing equipment 50 for secondary crushing and drying. Such a design enables the entire pulverizer to process materials continuously and efficiently.

[0070] Example 2: Reference Fig.10, improved on the basis of Example 1: a multifunctional cellulose material crushing and drying comprehensive processing system, which is used in the field of cellulose processing, and a separation box 49 is fixedly sleeved on the outer wall of the return air duct 8. This separation box 49 is connected to the return air duct 8, and a slot 42 is provided inside it. In the slot 42, a plug plate 43 is sealed and slidably connected. A hole 44 is provided inside the plug plate 43, and a filter cloth 45 is installed inside the hole 44. The function of this filter cloth 45 is to filter the dust in the hot air in the return air duct 8. When the hot air in the drying tower 6 enters the stirring shaft 7 through the return air duct 8, the filter cloth 45 can block the dust in the hot air, ensuring that the hot air entering the stirring shaft 7 is clean. When the dust on the filter cloth 45 accumulates to a certain extent, the plug plate 43 can be easily pulled out to clean or replace the filter cloth 45. Such a design not only ensures the cleanliness of the hot air, but also facilitates the maintenance and maintenance of the equipment.

[0071] Example 3: Reference Fig.11 , based on the improvement of Example 2: a plurality of equally spaced crushing cutters 51 are installed on the outer edge of the clamping plate 11. When the clamping plate 11 rotates at a high speed and with the cooperation of the high-temperature gas, the high-speed rotating crushing cutters 51 instantly crush and dry the material.

[0072] Example 4: Reference Fig.12 The multifunctional cellulose material crushing and drying comprehensive processing system comprises a box body 52 and a driving motor 55. A rotating shaft is rotatably installed in the box body 52, and a plurality of crushing blades 53 are fixedly installed on the outer wall of the rotating shaft. The rotating shaft passes through the box body 52 and extends to the bottom of the box body 52. ​​The rotating shaft is connected to the output shaft of the driving motor 55 through a synchronous belt and a synchronous wheel. A feed port 56 is arranged above the box body 52. ​​The feed port 56 is connected to the outlet of a heat exchanger 57 through a pipeline. The inlet 58 of the heat exchanger 57 It is the material inlet and air supply port. The discharge port of the box body 52 is connected to a small variable diameter drying tower 54. The hot air and material of the heat exchanger 57 have entered the box body 52. ​​The driving motor 55 drives multiple crushing blades 53 to rotate at high speed. The high-speed rotating crushing blades 53 instantly crush and dry the material. The high-speed rotation of the crusher can generate heat, plus the heat entering from the heat exchanger 57. There is a small variable diameter drying tower 54 at the outlet. In this way, the crushed and dried material comes out of the small variable diameter drying tower 54 as the crushed finished material.

[0073] The multifunctional cellulose material crushing and drying comprehensive treatment process includes the following steps:

[0074] S1. Allow the material with a moisture content of 40%-70% to directly enter the first processing equipment 1, and at the same time, hot air enters the first processing equipment 1 to crush and dry the material at the same time. The dried material enters the second processing equipment 50 through the conveying tube 2, and is crushed and dried again. The temperature of the incoming hot air can be controlled. After two crushing and drying, the desired moisture content is achieved. The drying operation can be completed without using hot air at a higher temperature, with low heat loss, high material crushing fineness, and a relatively short time. In addition, hot air enters during crushing, which can better dry and crush the material.

[0075] S2. During the specific operation, the material enters the crushing box 3, and the stirring shaft 7 and the grinding mechanism 10 are driven by the motor to rotate. The material is pushed outward under the centrifugal force of the grinding mechanism 10, and the stirring shaft 7 synchronously drives the clamping plate 11 and the grinding wheel 12 to rotate. The cooperation of the grinding wheel 12 and the annular grinding groove 14 can complete the crushing of the material, and multiple grinding mechanisms 10 are set to crush the material in multiple stages. The crushed material enters the return trough 15 under the guidance of the guide ring 18;

[0076] S3, start the exhaust fan 5, the exhaust fan 5 draws the air in the return trough 15 into the sieve box 20 through the sieve box 20 and the feed pipe 21, and at the same time, the air heated by the first heating plate 19 enters the return trough 15 through the air inlet 17, and then the hot air mixed with the crushed material moves upward along the threaded rotating ring 16 to dry the material, and the threaded rotating ring 16 can increase the drying time of the material. After entering the sieve box 20, the material falls on the sieve plate 22, and the stirring shaft 7 drives the protrusion 26 to rotate, and the protrusion 26 pushes the moving plate 2 4 moves outward, the moving plate 24 presses the lifting rod 30 downward through the trapezoidal block 29, so the lifting rod 30 can be controlled to move up and down reciprocatingly under the cooperation of the protrusion 26 and the first spring 28, and the lifting rod 30 can knock the screen plate 22 to screen the materials on the screen plate 22, and the materials with small particle size fall on the bottom inner wall of the screening box 20, and the materials with large particle size fall into the guide pipe 23 along the screen plate 22. When the leakage hole 25 is aligned with the guide pipe 23, the materials re-enter the upper part of the grinding mechanism 10 and are crushed again, which can ensure the particle size of the materials;

[0077] S4, the exhaust fan 5 conveys the hot air in the screening box 20 and the screened materials to the annular inner concave plate 32, and at the same time starts the second heating plate in the drying tower 6 to heat the annular inner concave plate 32 and the annular convex plate 33 in the drying tower 6, so as to facilitate drying the materials spread on the annular inner concave plate 32 and the annular convex plate 33; specifically, the rotating shaft 31 is driven by the motor to rotate, and the rotating shaft 31 drives the first spreading plate 34 and the second spreading plate 35 to rotate, and the first spreading plate 34 and the second spreading plate 35 are respectively connected to the annular inner concave plate 32 There is a gap between the first spreading plate 34 and the top of the annular convex plate 33, so the first spreading plate 34 can spread the material on the annular inner concave plate 32. In addition, when the second spreading plate 35 rotates, it can not only spread the material, but also cooperate with the arc block 39 and the second spring 41 to drive the first knocking ball 38 and the second knocking ball 40 to move up and down reciprocatingly to knock the annular inner concave plate 32 and the annular convex plate 33, so as to transport the material on the annular inner concave plate 32 and the annular convex plate 33 downward, so that the material can be flattened and dried for multiple times, thereby improving the drying efficiency;

[0078] S5, the material dried in the drying tower 6 enters the conveying cylinder 2 through the first material pipe 47, and can be transported to the second processing equipment 50 for secondary crushing and drying through the conveying of the auger 46, which not only reduces the heat loss during drying, but also improves the crushing fineness of the material, and the time is relatively short. In addition, hot air enters during crushing, which can better dry and crush the material;

[0079] S6. When the exhaust fan 5 conveys the hot air and the material into the drying tower 6, the hot air in the drying tower 6 flows back to the stirring shaft 7 through the return air duct 8, and preheats the material on the grinding mechanism 10 through the air vents 9, which greatly reduces the consumption of heat energy and improves the efficiency of subsequent drying. In addition, when the hot air in the drying tower 6 enters the stirring shaft 7 through the return air duct 8, the dust in the hot air can be filtered through the filter cloth 45 in the plug plate 43, and the plug plate 43 can be pulled out later to remove the dust on the filter cloth 45.

[0080] However, as is well known to those skilled in the art, the working principles and wiring methods of the exhaust fan 5 and the first heating plate 19 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.
