Abstract
Description
Technical Field
[0001] This utility model relates to the field of soluble cellulose sodium patch production technology, specifically a dryer for soluble cellulose sodium patch production. Background Technology
[0002] In the production of sodium soluble cellulose patches, the drying process of raw materials is a key step in ensuring product quality. Drying removes excess moisture from the raw materials, bringing them to the humidity standards required for subsequent production processes, while maintaining the stability of the physicochemical properties of sodium soluble cellulose.
[0003] For example, patent CN222951471U discloses a sodium carboxymethyl cellulose drying and processing device, including a base frame, a panel fixedly connected to the upper surface of the base frame, a drying mechanism fixedly connected to the upper surface of the panel, the drying mechanism including a first blower, the bottom surface of the first blower fixedly connected to the upper surface of the base frame, an air filter hood fixedly connected to the input end of the first blower, a heating chamber fixedly connected to the upper surface of the panel, a rotary air duct fixedly connected to the right side of the heating chamber, a gearbox fixedly connected to the upper surface of the rotary air duct, a high-speed motor fixedly connected to the input end of the gearbox, and a rotary air duct penetrating the output end of the gearbox. The air duct is fixedly connected to a centrifugal spray head, and the inner wall of the panel is fixedly connected to a drying tower. This drying and processing device is small in size, compact in design, and easy to move, making it convenient for small processing plants to use. However, when the raw material powder of sodium soluble cellulose is piled up inside the drying tank, the material thickness varies in different areas of the tank. When heat is transferred from the drying medium to the inside of the material, it needs to pass through multiple layers of powder particles. The deep or densely packed powder absorbs heat slowly and has a low temperature because the heat is blocked by the surface layer. The moisture is difficult to evaporate, forming an internal and external temperature difference and a drying gradient, resulting in uneven drying and affecting the overall raw material drying and processing effect.
[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing soluble cellulose sodium foil production dryer. Utility Model Content
[0005] The purpose of this invention is to provide a dryer for the production of sodium soluble cellulose sheets, in order to solve the problem mentioned in the background art that when the raw material powder of sodium soluble cellulose sheets is piled up inside the drying tank, the thickness of the material in different areas of the tank varies. When heat is transferred from the drying medium to the inside of the material, it needs to pass through multiple layers of powder particles. The deeper or densely packed powders are blocked by the surface layer, resulting in slow heat absorption, low temperature, and difficulty in evaporating moisture. This creates an internal and external temperature difference and a drying gradient, leading to uneven drying and affecting the overall drying and processing effect of the raw materials.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a dryer for producing soluble sodium cellulose plaster, comprising a drying tank for heating and drying soluble sodium cellulose plaster raw materials, a support frame externally mounted on the drying tank, a motor fixedly mounted on the upper end face of the support frame, a rotating shaft connected to the output end of the motor, the rotating shaft being slidably connected to the upper end face of the drying tank, and stirring blades fixed externally to the rotating shaft; a heat-conducting cover fixedly mounted on the inner wall of the drying tank, and multiple heating tubes fixed at equal angles inside the heat-conducting cover; a vibration mechanism provided on the support frame for controlling the shaking and dispersion of the soluble sodium cellulose plaster raw materials within the drying tank, wherein during the drying of the soluble sodium cellulose plaster raw materials, while stirring and dispersing the soluble sodium cellulose plaster raw materials, the up-and-down shaking of the drying tank can be controlled to intensify the shaking and dispersion of powder in the deeper internal positions, so that heat can be uniformly and quickly transferred to the powder, thereby improving the drying effect.
[0007] Preferably, the vibration mechanism includes a vibration table fixedly installed outside the drying tank, a sliding frame fixedly connected to the lower section of the vibration table; a base fixedly installed on the support frame, the sliding frame and the base being slidably connected through each other, and a vibration spring elastically connected between the base and the vibration table.
[0008] Preferably, a plurality of lifting rods are fixedly installed on the upper end face of the drying tank, and a transmission ring is fixedly installed on the lifting end of the lifting rod, and the transmission ring is coaxially sleeved on the outside of the rotating shaft.
[0009] Preferably, a drive shaft is rotatably connected to the support frame, and the rotation direction of the drive shaft is perpendicular to the rotation direction of the rotating shaft; a crank is fixedly connected to the drive shaft along the axial direction, and a pressure ring is fixedly sleeved on the crank, and the pressure ring rotates circumferentially to contact and compress the surface of the drive ring.
[0010] Preferably, a turbine is fixedly sleeved on the outside of the drive shaft, and a worm gear is meshed with the side of the turbine, with the worm gear fixedly sleeved on the outside of the rotating shaft.
[0011] Preferably, the drying tank is provided with a positioning mechanism for adjusting the height of the transmission ring.
[0012] Preferably, the positioning mechanism includes a threaded rod rotatably connected to the upper end face of the drying tank, and an internal threaded block is fitted onto the outer thread of the threaded rod, with the internal threaded block fixedly connected to the side of the transmission ring.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the dryer for the production of soluble cellulose sodium plaster can control the up-and-down shaking of the drying tank while stirring and dispersing the soluble cellulose sodium plaster raw material during the drying process, thereby increasing the shaking and dispersion of powder in the deep internal position, so that heat can be evenly and quickly transferred to the powder and improving the drying process effect.
[0014] The support frame is equipped with a vibration mechanism that controls the shaking and dispersion of the soluble sodium cellulose raw material inside the drying tank. The rotating shaft drives the stirring blades to rotate, stirring and dispersing the powder inside the drying tank. Under the transmission of the worm gear, the transmission shaft and crank rod can be driven to rotate. The pressure ring on the crank rod intermittently contacts and presses against the transmission ring. The transmission ring drives the drying tank to move synchronously longitudinally. With the cooperation of the sliding frame and the vibration spring, the drying tank vibrates up and down, which intensifies the movement and dispersion of the powder inside and maintains uniform heat transfer.
[0015] The drying tank is equipped with a positioning mechanism to adjust the height of the transmission ring. According to the processing needs, the position of the transmission ring above the drying tank can be adjusted by rotating the threaded rod, thereby adjusting the distance of the transmission ring being pushed by the pressure ring. This causes the vertical vibration amplitude of the drying tank to change, so as to control the degree of powder dispersion inside, maintain uniform powder drying, and reduce motor energy consumption.

[0024] 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.
[0025] Example 1: Please refer to Figures 1-3 The present invention provides the following technical solution: a dryer for the production of soluble cellulose sodium plaster, comprising a drying tank 1 for heating and drying soluble cellulose sodium plaster raw materials, a support frame 2 is provided on the outside of the drying tank 1, a motor 3 is fixedly installed on the upper end face of the support frame 2, a rotating shaft 4 is connected to the output end of the motor 3, the rotating shaft 4 is slidably connected to the upper end face of the drying tank 1, and a stirring blade 5 is fixed on the outside of the rotating shaft 4; a heat-conducting cover 6 is fixed on the inner wall of the drying tank 1, and multiple heating tubes 7 are fixed at equal angles inside the heat-conducting cover 6; a vibration mechanism is provided on the support frame 2 to control the shaking of the drying tank 1 to disperse the distribution gap of the soluble cellulose sodium plaster raw materials inside.
[0026] Please see Figures 2-4 The vibration mechanism includes a vibration table 8 fixedly installed outside the drying tank 1, with a sliding frame 9 fixedly connected to the lower section of the vibration table 8; a base 10 is fixedly installed on the support frame 2, the sliding frame 9 and the base 10 are slidably connected through each other, and a vibration spring 11 is elastically connected between the base 10 and the vibration table 8. Multiple lifting rods 12 are fixedly installed on the upper end face of the drying tank 1, and a transmission ring 13 is fixedly installed on the lifting end of the lifting rod 12. The transmission ring 13 is coaxially sleeved on the outside of the rotating shaft 4.
[0027] Please see Figures 5-7 A drive shaft 14 is rotatably connected to the support frame 2, and the rotation direction of the drive shaft 14 is perpendicular to the rotation direction of the rotating shaft 4. A crank 15 is fixedly connected to the drive shaft 14 along its axial direction, and a pressure ring 16 is fixedly sleeved on the crank 15. The pressure ring 16 rotates circumferentially and contacts and presses against the surface of the drive ring 13. A turbine 141 is fixedly sleeved on the outside of the drive shaft 14, and a worm gear 142 is meshed with the side of the turbine 141. The worm gear 142 is fixedly sleeved on the outside of the rotating shaft 4.
[0028] Soluble cellulose sodium ester powder is introduced into the drying tank 1 through the feed inlet. The motor 3 controls the rotating shaft 4 to rotate, and the rotating shaft 4 drives the stirring blade 5 to rotate. The stirring blade 5 rotates inside the drying tank 1, and the rotation of the stirring blade 5 disperses the powder inside the drying tank 1, so that the heat generated by the heating tube 7 can be transferred to the powder more evenly, thereby achieving the purpose of drying the soluble cellulose sodium ester powder.
[0029] As the rotating shaft 4 rotates, it drives the externally fixed worm gear 142 to rotate synchronously. The worm gear 142 meshes with the turbine gear 141, and under the meshing transmission, it can drive the turbine gear 141 to rotate. The turbine gear 141 can drive the transmission shaft 14 to rotate, and the transmission shaft 14 drives the crank 15 to rotate, so that the pressure ring 16 on the crank 15 contacts the surface of the transmission ring 13 during transmission. When the pressure ring 16 rotates in a circle, it generates a squeezing force on the transmission ring 13, pushing the transmission ring 13 and the drying tank 1 to move downward. The drying tank 1, which is sleeved outside the rotating shaft 4, moves downward and is fixed outside the drying tank 1. The vibration table 8 moves synchronously, which pushes the sliding frame 9 through the base 10 to move downwards, pressing the vibration spring 11 on the base 10. When the pressure ring 16 rotates and separates from the surface of the transmission ring 13, the vibration table 8, the drying tank 1, and the transmission ring 13 can be pushed upwards and reset under the thrust of the vibration spring 11. This process is repeated to achieve the purpose of up-and-down vibration of the drying tank 1. The powder inside is more dispersed under the up-and-down vibration, and the heat can be evenly transferred to the deep powder layer, improving the drying and processing effect of soluble cellulose sodium powder raw materials.
[0030] Example 2: Please refer to Figure 6 and Figure 7 Based on Embodiment 1, a positioning mechanism is also disclosed, the specific structure of which is as follows: A positioning mechanism for adjusting the height position of the transmission ring 13 is provided on the drying tank 1. The positioning mechanism includes a threaded rod 131 rotatably connected to the upper end face of the drying tank 1, and an internal threaded block 132 is sleeved on the outer thread of the threaded rod 131. The internal threaded block 132 is fixedly connected to the side of the transmission ring 13.
[0031] According to the needs of powder drying processing, the vibration amplitude of the drying tank 1 can be adjusted, the rotation of the threaded rod 131 can be controlled, and the internal threaded block 132 can be controlled to move longitudinally outside it under the threaded drive. The internal threaded block 132 drives the transmission ring 13 to move longitudinally synchronously. Adjusting the distance of the transmission ring 13 at the upper end of the drying tank 1, thereby adjusting the distance of the transmission ring 13 below the pressure ring 16. When the pressure ring 16 rotates circumferentially under the drive of the crank rod 15, the distance of contact and compression between it and the surface of the transmission ring 13 changes, and the vibration amplitude of the drying tank 1 also changes. Thus, the purpose of adjusting the amplitude of the drying tank 1 can be achieved, maintaining uniform powder drying processing while reducing the energy consumption of the motor 3.
