Description

Technical Field

[0001] This utility model relates to the field of cellulose acetate production and processing technology, and in particular to a water washing device for cellulose acetate production and processing. Background Technology

[0002] Cellulose acetate is an important chemical raw material widely used in industries such as textiles, plastics, and coatings. In the production process of cellulose acetate, washing is one of the key steps, directly affecting the purity and quality of the product. Currently, the production process of cellulose acetate mainly includes esterification, hydrolysis, neutralization, and washing. Among these steps, washing is crucial for removing residual acid and catalyst. With the increasing environmental protection requirements and the improvement of product quality standards, efficient, energy-saving, and environmentally friendly washing equipment has become a key direction for industry development.

[0003] The cellulose acetate washing device mainly consists of a washing tank, a stirring component, a feeding and discharging mechanism, and a heating and temperature control component. Its working principle is as follows: the cellulose acetate to be washed is fed into the washing tank through the feeding mechanism. The blades of the stirring component rotate at high speed to fully mix the material with the water, thereby removing residual impurities. The heating and temperature control component adjusts the water temperature according to the process requirements to improve the washing efficiency. After washing, the qualified cellulose acetate is discharged through the discharging mechanism, completing the entire washing process.

[0004] Currently, some cellulose acetate washing equipment frequently experiences blockages when adding materials to the tank. This not only reduces production efficiency, extends the production cycle, and increases production costs, but also leads to material waste and affects product consistency and stability. Therefore, a washing device for cellulose acetate production and processing is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a water washing device for the production and processing of cellulose acetate, which aims to improve the problem of clogging during the feeding process in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A washing device for the production and processing of cellulose acetate includes a housing, a feeding box fixedly connected to the top of the housing, a plurality of support columns fixedly connected to the bottom of the housing, a feeding mechanism inside the feeding box, a reciprocating mechanism inside the housing, and a circulation mechanism outside the housing.

[0008] The feeding mechanism includes a fixed box, the front end of which is fixedly connected to the outside of the fixed box. A sliding block is slidably connected inside the fixed box, an impact rod is fixedly connected to the outside of the sliding block, and a receiving rod is fixedly connected to the outside of the feeding box. The impact rod contacts the outside of the receiving rod. A telescopic column is fixedly connected to the top of the sliding block, and a spring is sleeved on the outside of the telescopic column. A pressing block is rotatably connected inside the feeding box, and a feeding assembly is provided on the outside of the feeding box.

[0009] Through the above technical solution: the support column ensures the stability of the entire device and provides conditions for the normal operation of each mechanism. In the feeding mechanism, the fixed box, sliding block, impact rod, impact rod, telescopic column, spring and pressure block cooperate with each other. When the pressure block rotates, it can intermittently press the sliding block, causing the sliding block to slide in the fixed box, which in turn drives the impact rod to hit the impact rod and generate vibration. This effectively prevents the cellulose acetate raw material from clogging and adhering in the feeding box, ensuring that the raw material can enter the shell from the feeding box evenly and smoothly, preparing for the subsequent water washing process.

[0010] As a further description of the above technical solution:

[0011] The top end of the telescopic column is fixedly connected to the inside of the fixed box, and the bottom end of the sliding block is in contact with the outside of the pressing block;

[0012] Through the above technical solution, the fixed telescopic column ensures that it can stably guide the movement direction of the sliding block, while the contact and cooperation between the sliding block and the pressure block ensures that the pressure block can effectively apply pressure to the sliding block when it rotates, making the operation of the feeding mechanism more stable and reliable.

[0013] As a further description of the above technical solution:

[0014] The top end of the spring is fixedly connected to the inside of the fixed box, and the bottom end of the spring is fixedly connected to the top end of the sliding block.

[0015] Through the above technical solution, the connection method of the spring enables it to accurately play a buffering and resetting role when the sliding block is compressed and the compression is released, further ensuring the impact effect between the impact rod and the impacted rod and improving the smoothness of material feeding.

[0016] As a further description of the above technical solution:

[0017] The feeding assembly includes a second motor, which is externally fixedly connected to the rear end of the feeding box. A rotating blade is fixedly connected to the drive end of the second motor, and the front end of the rotating blade is fixedly connected to the rear end of the pressing block.

[0018] Through the above technical solution: Motor 2 provides power for the feeding process, drives the rotating blade to rotate and transport raw materials, and at the same time drives the pressing block to rotate synchronously, realizing the automated control of the feeding process and improving feeding efficiency and stability.

[0019] As a further description of the above technical solution:

[0020] The reciprocating mechanism includes a sliding column, which is slidably connected to the outside of the housing. A fixing block is fixedly connected to the bottom end of the sliding column. A filter screen is rotatably connected to one side of the inner wall of the housing. A telescopic plate is rotatably connected to the front end of the filter screen. A rotating plate is rotatably connected to the front end of the telescopic plate. A transmission rod is fixedly connected to the top end of the sliding column. A rotating column is slidably connected to the outside of the transmission rod. A stirring assembly is provided on the outside of the housing.

[0021] Through the above technical solution, the reciprocating mechanism, through the linkage of various components, enables the filter screen to swing during the washing process, thereby filtering and separating the material, effectively preventing impurities from clogging the filter and improving the cleaning effect. At the same time, the rotating plate facilitates the discharge of the material after cleaning.

[0022] As a further description of the above technical solution:

[0023] The stirring assembly includes a motor, the bottom end of which is fixedly connected to the top end of the housing, a stirring shaft fixedly connected to the drive end of the motor, the outside of which is rotatably connected to the inside of the housing, a plurality of stirring blades fixedly connected to the outside of which is the stirring shaft, and the outside of which is fixedly connected to the outside of the stirring shaft.

[0024] Through the above technical solution: the motor drives the stirring shaft and stirring blades to rotate, stirring the water flow inside the shell, so that cellulose acetate can fully contact the water, which significantly improves the washing effect. At the same time, the stirring shaft drives the rotating column to rotate, providing power for the reciprocating mechanism and realizing the coordinated work between the mechanisms.

[0025] As a further description of the above technical solution:

[0026] The circulation mechanism includes a water pump, which is fixedly connected to the outside of the housing. An input pipe is fixedly connected to the input end of the water pump, and an output pipe is fixedly connected to the output end of the water pump. Multiple nozzles are fixedly connected inside the housing, and a filter screen is fixedly connected inside the housing.

[0027] Through the above technical solution, the circulation mechanism realizes the recycling of water resources through the cooperation of water pump, input pipe, output pipe and nozzle. The filter screen can filter impurities in the water, ensuring the quality of the circulating water. This not only saves water resources, but also reduces production costs and improves the washing effect.

[0028] As a further description of the above technical solution:

[0029] The input tube is externally fixedly connected to the inside of the housing, and the output tube is externally fixedly connected to the inside of the housing;

[0030] The above technical solution, through the connection method of the input and output pipes to the housing, ensures that the water pump can accurately draw water from inside the housing and smoothly return the water to the housing, thus ensuring the normal operation of the circulation mechanism and further guaranteeing the efficient operation of the water washing device.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, during the feeding process before washing cellulose acetate, the raw material is placed into the feeding box, the motor is started, the motor drives the rotating blade to transport the raw material, and drives the pressing block to rotate. The pressing block intermittently presses the sliding block to make it slide in the fixed box. When the pressing is released, the spring pushes the sliding block, causing the impact rod to hit the impact rod and generate vibration, which avoids the raw material from being blocked and attached in the feeding box, and ensures that the raw material enters the washing device smoothly, laying a good foundation for the subsequent cleaning process.

[0033] 2. In this invention, after the raw materials enter the device, the water pump draws the internal water flow and circulates it for spraying, realizing the recycling of water resources. The motor is started to drive the stirring shaft and stirring blades to agitate the water flow, improving the cleaning effect. At the same time, the motor drives the rotating column to push the transmission rod, causing the sliding column and fixed block to pull the filter screen to swing, preventing impurities from clogging it. After cleaning, the rotating plate is rotated to adjust the telescopic plate, tilting the filter screen. The motor is started again to make the filter screen shake, realizing the automatic discharge of materials, improving cleaning efficiency and material unloading convenience.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a washing device for the production and processing of cellulose acetate, comprising a shell 1, a feeding box 4 fixedly connected to the top of the shell 1 for storing cellulose acetate raw materials to be washed, and multiple support columns 5 fixedly connected to the bottom of the shell 1 for stabilizing and supporting the shell 1, ensuring that the entire device remains stable during operation and avoiding the washing effect due to shaking or tilting. The feeding box 4 is provided with a feeding mechanism 6, which can effectively control the feeding process of cellulose acetate raw materials, ensuring that the raw materials enter the shell 1 evenly and smoothly. The shell 1 is provided with a reciprocating mechanism 2, which can make the material swing during the washing process, which helps to improve the washing effect and avoid impurities from clogging. The shell 1 is provided with a circulation mechanism 3, which can realize the recycling of water resources, saving water resources and reducing production costs.

[0042] Specifically, when the washing operation begins, the cellulose acetate raw material is stored in the feeding box 4. On the basis of stable operation of the device, the feeding mechanism 6 starts to work, feeding the raw material evenly and smoothly into the shell 1 to prepare for subsequent washing. At the same time, the circulation mechanism 3 starts water circulation, and the reciprocating mechanism 2 prepares to make the material swing.

[0043] The feeding mechanism 6 includes a fixed box 62, which provides space for the installation and movement of the components in the feeding mechanism 6. The fixed box 62 is externally fixedly connected to the front end of the feeding box 4 to ensure a tight fit. A sliding block 63 is slidably connected inside the fixed box 62, which can slide flexibly within the fixed box 62 to provide power transmission for subsequent impact actions. An impact rod 67 is externally fixedly connected to the sliding block 63, and the impact rod 67 moves as the sliding block 63 slides. A receiving rod 68 is externally fixedly connected to the feeding box 4, and the impact rod 67 contacts the outside of the receiving rod 68. When the impact rod 67 moves, it impacts the receiving rod 68, generating a vibration effect to prevent the raw material in the feeding box 4 from clogging and adhering. A telescopic column 65 is fixedly connected to the top of the sliding block 63, and the telescopic column 65 guides the movement direction of the sliding block 63. With a certain supporting function, the telescopic column 65 is fitted with a spring 66 on the outside. The spring 66 plays a buffering and resetting role when the sliding block 63 is compressed and the compression is released. The inside of the feeding box 4 is rotatably connected to the pressing block 64. The rotation of the pressing block 64 can generate intermittent pressing force on the sliding block 63. The outside of the feeding box 4 is provided with a feeding assembly 61. The feeding assembly 61 is the key part to control the feeding process. The top end of the telescopic column 65 is fixedly connected to the inside of the fixed box 62 to ensure the stability of the telescopic column 65. The bottom end of the sliding block 63 is in contact with the outside of the pressing block 64 to ensure that the pressing block 64 can effectively apply pressure to the sliding block 63. The top end of the spring 66 is fixedly connected to the inside of the fixed box 62, and the bottom end of the spring 66 is fixedly connected to the top end of the sliding block 63, so that the spring 66 can accurately generate elastic force on the sliding block 63.

[0044] Specifically, during material feeding, the feeding component 61 drives the pressing block 64 to rotate, and the pressing block 64 intermittently presses the sliding block 63. The sliding block 63 slides in the fixed box 62, causing the impact rod 67 to strike the impact rod 68 to generate vibration, preventing the raw material from blocking and adhering. At the same time, the telescopic column 65 guides the direction, and the spring 66 buffers and resets, ensuring a smooth feeding process.

[0045] The feeding assembly 61 includes a second motor 611, which provides power for the feeding process. The second motor 611 is externally fixedly connected to the rear end of the feeding box 4, ensuring installation stability. A rotating blade 612 is fixedly connected to the drive end of the second motor 611. The second motor 611 drives the rotating blade 612 to rotate inside the feeding box 4, thereby conveying the raw materials inside the feeding box 4. The front end of the rotating blade 612 is fixedly connected to the rear end of the pressing block 64, so that the rotating blade 612 can drive the pressing block 64 to rotate synchronously when it rotates. The circulation mechanism 3 includes a water pump 31, which is the power source for water circulation. The water pump 31 is externally fixedly connected to the outside of the housing 1 for easy installation and maintenance. The input end of pump 31 is fixedly connected to an input pipe 32, which is used to draw water from inside the housing 1. The output end of pump 31 is fixedly connected to an output pipe 34, which delivers the drawn water to the required location. Multiple nozzles 35 are fixedly connected inside the housing 1, which spray water evenly inside the housing 1 to improve the washing effect. A second filter screen 33 is fixedly connected inside the housing 1, which can filter impurities in the water and ensure the quality of the circulating water. The outside of the input pipe 32 is fixedly connected to the inside of the housing 1 to ensure accurate water extraction from inside the housing 1. The outside of the output pipe 34 is fixedly connected to the inside of the housing 1 so that water can smoothly return to the housing 1.

[0046] Specifically, motor 611 starts, driving the rotating blade 612 to rotate and transport raw materials. At the same time, it drives the pressing block 64 to rotate and participate in the work of the feeding mechanism 6. Water pump 31 starts, drawing water from the housing 1 through the input pipe 32 and delivering it to the nozzle 35 through the output pipe 34. The nozzle 35 sprays water evenly. During the process, filter screen 33 filters impurities, realizing the recycling of water resources and improving the washing effect.

[0047] Reference Figures 1 to 2 The reciprocating mechanism 2 includes a sliding column 21, which is externally slidably connected to the inside of the housing 1. A fixing block 22 is fixedly connected to the bottom end of the sliding column 21. A filter screen 23 is rotatably connected to one side of the inner wall of the housing 1. The filter screen 23 filters and separates materials during the washing process and swings under the action of the reciprocating mechanism 2 to improve the cleaning effect. A telescopic plate 25 is rotatably connected to the front end of the filter screen 23. The telescopic plate 25 can adaptively adjust its length to adapt to the swinging and tilting of the filter screen 23. A rotating plate 26 is rotatably connected to the front end of the telescopic plate 25. The rotation of the rotating plate 26 can control the movement of the telescopic plate 25. The rotating plate 26 acts as a door inside the housing 1 to facilitate the discharge of materials after cleaning. A transmission rod 24 is fixedly connected to the top end of the sliding column 21. A rotating column 27 is slidably connected to the outside of the transmission rod 24. The rotation of the rotating column 27 can push the transmission rod 24 to slide. A stirring assembly 28 is provided on the outside of the housing 1.

[0048] Specifically, during the washing process, the stirring component 28 drives the rotating column 27 to rotate, the rotating column 27 pushes the transmission rod 24 to slide, the transmission rod 24 drives the sliding column 21 to slide inside the housing 1, and the sliding column 21 pulls the filter screen 23 to swing through the fixed block 22 to filter and separate the material, thereby improving the cleaning effect. At the same time, the rotating plate 26 can be rotated to control the telescopic plate 25, which facilitates the discharge of the material after cleaning.

[0049] The stirring assembly 28 is used to agitate the water flow inside the housing 1 to improve the cleaning effect. The stirring assembly 28 includes a motor 281, which provides power for the stirring process. The bottom end of the motor 281 is fixedly connected to the top end of the housing 1 to ensure the stability of the installation. The driving end of the motor 281 is fixedly connected to the stirring shaft 282. The motor 281 drives the stirring shaft 282 to rotate inside the housing 1. The outside of the stirring shaft 282 is rotatably connected to the inside of the housing 1 to ensure that the stirring shaft 282 can rotate stably. Multiple stirring blades 283 are fixedly connected to the outside of the stirring shaft 282. The stirring blades 283 agitate the water flow as the stirring shaft 282 rotates. The outside of the rotating column 27 is fixedly connected to the outside of the stirring shaft 282 so that the rotating column 27 can rotate as the stirring shaft 282 rotates.

[0050] Specifically, when motor 281 starts, it drives the stirring shaft 282 to rotate stably inside the housing 1. The stirring shaft 282 drives the stirring blade 283 to agitate the water flow and improve the washing effect. At the same time, the rotation of the stirring shaft 282 drives the rotating column 27 to rotate, providing power for the reciprocating mechanism 2.

[0051] Working principle: When the processor needs to wash cellulose acetate, the cellulose acetate raw material is placed into the feeding box 4 and the motor 611 is started. The motor 611 drives the rotating blade 612 to rotate inside the feeding box 4, thus conveying the raw material inside the feeding box 4. At the same time, the pressing block 64 rotates with the rotating blade 612, thereby intermittently pressing the sliding block 63, causing the sliding block 63 to slide inside the fixed box 62. When the pressing block 64 releases the pressure on the sliding block 63, the spring 66 automatically pushes the sliding block 63 to slide inside the fixed box 62, thereby causing the impact rod 67 to collide with the impact rod 68, generating a vibration effect. This causes the raw material inside the feeding box 4 to vibrate, preventing blockage and adhesion during feeding and ensuring the smooth progress of the cleaning process.

[0052] After the raw materials are inside the shell 1, the water pump 31 draws water from inside the shell 1 through the input pipe 32 and sprays it back into the shell 1 through the output pipe 34 and the nozzle 35 to achieve water circulation, reducing water waste. At the same time, the motor 281 is started, which drives the stirring shaft 282 to rotate inside the shell 1, causing the stirring blades 283 to agitate the water inside the shell 1 and improve the cleaning effect. Meanwhile, the rotating column 27 intermittently pushes the transmission rod 24 to slide inside the shell 1 as the motor 281 rotates, thereby causing the sliding column 21 and the fixed block 2 to move. 2. The filter screen 23 is pulled back and forth, causing it to swing inside the housing 1. This swings the material, preventing impurities from clogging the filter and improving the cleaning effect. When the cleaned material needs to be cleaned, the rotating plate 26 is rotated outside the housing 1, allowing the telescopic plate 25 to adjust its length adaptively. The filter screen 23 is then tilted inside the housing 1. At this time, the motor 281 is started, causing the filter screen 23 to shake again. The material is then automatically discharged from the housing 1 as the filter screen 23 shakes, achieving an automatic feeding effect.
