[0034] The present disclosure provides a stirring device for water transfer printing paper slurry, including a tank cylinder, a cover plate, a stirring assembly and a steam delivery pipe. The tank cylinder is provided with a stirring cavity for containing starch slurry. A driving motor is fixedly installed on the cover plate, and a feeding port communicating with the stirring cavity is provided on the cover plate. The stirring assembly includes a stirring main shaft and stirring blades; one end of the stirring main shaft is connected to the power output shaft of the driving motor, the other end of the stirring main shaft extends into the stirring cavity, the stirring blades are detachably connected to the other end of the stirring main shaft, and a plurality of through holes are distributed on the stirring blades. The air outlet of one end of the steam delivery pipe penetrates through the cover plate and extends into the stirring cavity, and the air inlet of the other end of the steam delivery pipe is communicated with a steam pressure pump (not shown in the figure).
[0035] Please refer to Figures 1 to 4 , to better understand the stirring device 10 for water transfer printing paper slurry of the present application, the following further explains the stirring device 10 for water transfer printing paper slurry:
[0036] The stirring device 10 for the water transfer printing paper slurry of an embodiment includes a tank cylinder 100, a cover plate 200, a stirring assembly 400, and a steam delivery pipe 500. The tank cylinder 100 is provided with a stirring cavity 101 for containing starch slurry. A driving motor 300 is fixedly installed on the cover plate 200, and a feeding port 201 communicating with the stirring cavity 101 is provided on the cover plate 200. The stirring assembly 400 includes a stirring main shaft 410 and stirring blades 420; one end of the stirring main shaft 410 is connected to the power output shaft of the driving motor 300, the other end of the stirring main shaft 410 extends into the stirring cavity 101, the stirring blades 420 are detachably connected to the other end of the stirring main shaft 410, and a plurality of through holes 4201 are distributed on the stirring blades 420. The air outlet of one end of the steam delivery pipe 500 penetrates through the cover plate 200 and extends into the stirring cavity 101, and the air inlet of the other end of the steam delivery pipe 500 is communicated with a steam pressure pump (not shown in the figure).
[0037] In this embodiment, water vapor for heating is directly introduced into the starch slurry in the stirring cavity 101 through the steam delivery pipe 500, so that the heat carried by the water vapor is directly transferred to the starch slurry, effectively replacing the traditional jacket type heat transfer method, thereby making the heating effect of the starch slurry more uniform and preventing the problem of overheating and burning of local starch slurry.
[0038] Furthermore, the driving motor 300 is used to drive the stirring main shaft 410 to drive the stirring blades 420 to stir the starch slurry. Among them, by using the plurality of through holes 4201 distributed on the stirring blades 420, the resistance effect of stirring can be reduced, so that the stirring and heating effects on the starch slurry are more uniform; at the same time, the setting of the plurality of through holes 4201 on the blades can also effectively reduce the excessive overflow of the viscous starch slurry during the stirring process, thereby effectively avoiding the problem that the overflow bubbles float to the liquid surface, burst and splash, and adhere to the feeding port 201.
[0039] It should be noted that the number of the steam delivery pipes 500 can be set to be multiple, so that the steam delivery pipes 500 can more efficiently transfer the heat carried by the water vapor directly to the starch slurry, so as to improve the heating rate of the stirring device 10 for the water transfer printing paper slurry and effectively avoid the heat loss rate.
[0040] Such as Figures 1 to 4As shown, in one embodiment, the stirring paddle 420 includes a first stirring paddle 4210, a second stirring paddle 4220, and a third stirring paddle 4230; the first stirring paddle 4210, the second stirring paddle 4220, and the third stirring paddle 4230 are fixedly connected to the stirring main shaft 410 in sequence. In one embodiment, a plurality of through holes 4201 are located on the first stirring paddle 4210. In one embodiment, the aperture range of each through hole 4201 is between 10 millimeters and 20 millimeters.
[0041] It can be understood that since the starch slurry after heating and gelatinization is relatively viscous, by providing the first stirring paddle 4210, the second stirring paddle 4220, and the third stirring paddle 4230, the starch slurry can be better stirred in layers simultaneously, making the stirring and the heating effect of the starch slurry more uniform, and effectively preventing the phenomenon of caking in the starch slurry.
[0042] Furthermore, since the air outlet at one end of the steam delivery pipe 500 is located below the liquid level of the starch slurry, when the steam supply system delivers water vapor to the steam delivery pipe 500, there will be a situation of overflowing bubbles in the starch slurry, and at the same time, the overflowing bubbles will also float to the liquid surface of the starch slurry and burst, resulting in the problem that the starch slurry splashes to the feeding port 201. In this embodiment, by providing a plurality of through holes 4201 on the first stirring paddle 4210, the resistance effect of stirring can be reduced, making the starch slurry more evenly affected by stirring and heating, so that the overflowing bubbles can be stirred and broken before floating to the liquid surface of the starch slurry, thus effectively solving the problem that the overflowing bubbles float to the liquid surface, burst, splash, and adhere to the feeding port 201.
[0043] In this embodiment, the first stirring paddle 4210, the second stirring paddle 4220, and the third stirring paddle 4230 are sequentially connected to the stirring main shaft 410 by screws; in other embodiments, the first stirring paddle 4210, the second stirring paddle 4220, and the third stirring paddle 4230 can also be sequentially welded to the stirring main shaft 410, so as to effectively ensure the reliability of the connection between the first stirring paddle 4210, the second stirring paddle 4220, and the third stirring paddle 4230 and the stirring main shaft 410 respectively.
[0044] As Figures 1 to 4 shown, in one embodiment, the stirring device 10 for water transfer printing paper slurry further includes a hot air diversion pipe 600, one end of the hot air diversion pipe 600 penetrates through the cover plate 200 and communicates with the stirring cavity 101, and the other end of the hot air diversion pipe 600 communicates with a hot air reflux system (not shown in the figure). In one embodiment, the stirring device 10 for water transfer printing paper slurry further includes a cover plate 700, and the cover plate 700 is used to cover the feeding port 201.
[0045] It can be understood that when the stirring device 10 for the water transfer printing paper slurry stirs and heats the starch slurry in the stirring cavity 101, the operator can cover the cover plate 700 at the feeding port 201 to effectively prevent foreign objects from falling into the stirring cavity 101 through the feeding port 201, thereby ensuring the stirring quality of the starch slurry. At the same time, the excess heat generated in the stirring cavity 101 can be discharged to the hot gas reflux system (not shown in the figure) through the hot gas diversion pipe 600, effectively avoiding the situation of overheating and pressure in the stirring cavity 101, so as not to affect the stirring and heating effect of the starch slurry.
[0046] As Figure 4 shown, in one embodiment, a slurry discharge pipe 110 communicating with the stirring cavity 101 is provided at the bottom of the tank cylinder 100, and a throttle valve (not shown in the figure) is installed on the slurry discharge pipe 110. It can be understood that the on-off of the slurry discharge pipe 110 is controlled by the throttle valve (not shown in the figure) to realize the discharge and throttling storage of the starch slurry.
[0047] As Figure 1 and Figure 4 shown, in one embodiment, a first structural support portion 210 and a second structural support portion 220 are provided on the cover plate 200, the first structural support portion 210 and the second structural support portion 220 are respectively welded to the cover plate 200, and the drive motor 300 is fixedly installed on the first structural support portion 210 and the second structural support portion 220.
[0048] It can be understood that by respectively welding the first structural support portion 210 and the second structural support portion 220 to the cover plate 200, the structural rationality of the fixed installation of the drive motor 300 is effectively increased.
[0049] As Figures 1 to 3 shown, in one embodiment, the stirring device 10 for the water transfer printing paper slurry further includes a temperature control detection tube 800. One end of the temperature control detection tube 800 protrudes from the cover plate 200 and is electrically connected to a temperature control panel (not shown in the figure). The other end of the temperature control detection tube 800 penetrates through the cover plate 200 and extends into the stirring cavity 101, and a temperature detection sensor (not shown in the figure) is provided at the other end of the temperature control detection tube 800.
[0050] It can be understood that the real-time temperature monitoring of the starch slurry is realized through the temperature detection sensor (not shown in the figure) at the other end of the temperature control detection tube 800, so as to ensure the heating effect of the starch slurry.
[0051] It should be noted that the stirring device 10 for the water transfer printing paper slurry of the present disclosure only protects the electrical connection relationship between each component and the temperature control detection tube 800, while the temperature control panel (not shown in the figure) and the temperature detection sensor (not shown in the figure) belong to the prior art and are not within the protection scope of the present disclosure.
[0052] As Figure 2 shown, in one embodiment, the first stirring blade 4210, the second stirring blade 4220 and the third stirring blade 4230 are all integrally formed structures.
[0053] It can be understood that since the starch slurry after heating and gelatinization is relatively viscous, the stirring blades 420 of the stirring device 10 for the water transfer printing paper slurry need to bear a relatively large stirring resistance of the starch slurry. In this embodiment, the first stirring blade 4210, the second stirring blade 4220 and the third stirring blade 4230 are all designed as integrally formed structures, effectively improving the structural strength of each stirring blade 420, thereby ensuring the stirring quality of the starch slurry.
[0054] As Figure 1 and Figure 3 shown, in one embodiment, a plurality of mounting and supporting parts 900 are convexly provided on the outer peripheral wall of the tank barrel 100, and the plurality of mounting and supporting parts 900 are arranged in a circumferential distribution.
[0055] It can be understood that through the plurality of mounting and supporting parts 900, the whole stirring device 10 for the water transfer printing paper slurry can be reliably positioned and installed, ensuring the stability of stirring.
[0056] The present application also provides a stirring equipment for the water transfer printing paper slurry, including the stirring device 10 for the water transfer printing paper slurry described in any of the above embodiments.
[0057] In this embodiment, water vapor for heating is directly introduced into the starch slurry in the stirring cavity through a steam delivery pipe, so that the heat carried by the water vapor is directly transferred to the starch slurry, effectively replacing the traditional jacket type heat transfer method, thereby making the heating effect of the starch slurry more uniform and preventing the problem of local starch slurry overheating and burning.
[0058] Furthermore, the driving motor is used to drive the stirring main shaft to drive the stirring blades to stir the starch slurry. Among them, by using a plurality of through holes distributed on the stirring blades, the stirring resistance effect can be reduced, making the stirring and heating effects on the starch slurry more uniform; at the same time, the setting of a plurality of through holes on the blades can also effectively reduce the excessive overflow of the viscous starch slurry during the stirring process, thereby effectively avoiding the problem that the overflow bubbles float to the liquid surface, burst and splash and adhere to the feeding port.
[0059] Compared with the prior art, the present utility model has at least the following advantages:
[0060] 1. Directly introduce the steam for heating and temperature raising into the starch slurry in the stirring cavity through the steam delivery pipe, so that the heat carried by the steam is directly transferred to the starch slurry, effectively replacing the traditional jacket-type heat transfer method, thus making the heating effect of the starch slurry more uniform and preventing the problem of overheating and burning of local starch slurry.
[0061] 2. Drive the stirring main shaft through the driving motor to drive the stirring blades to stir the starch slurry. Among them, by using the multiple through holes distributed on the stirring blades, the resistance effect of stirring can be reduced, making the stirring and heating effects on the starch slurry more uniform; at the same time, the setting of the multiple through holes on the blades can also effectively reduce the excessive foaming of the viscous starch slurry during the stirring process, thus effectively avoiding the problem that the foams float to the liquid surface, break and splash, and adhere to the feeding port.
[0062] The above-described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
