Utility Model Content

[0005] The purpose of this invention is to provide a quantitative pulping device for kraft paper preparation. After the material discharged from the temporary storage tank is collected through the transfer pipe, the inside of the collection pipe at the material collection position is temporarily rotated by the stirring blade to collect the falling material at different positions and make the material fall on the rotation trajectory of the stirring blade. This can directly improve the stirring and mixing efficiency and solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quantitative pulping device for kraft paper preparation, comprising a stirring frame, a collecting pipe provided on one side of the upper end of the stirring frame, temporary storage tanks provided on both sides of the upper end of the collecting pipe, a transmission pipe provided between the lower end of the temporary storage tank and the collecting pipe, the transmission pipe being sealed to the collecting pipe, and a stirring blade vertically arranged inside the collecting pipe.

[0007] Preferably, an electronic valve is provided between the transmission pipe and the temporary storage tank, and the temporary storage tank, the electronic valve and the transmission pipe are sequentially and sealed together.

[0008] Preferably, a second motor is provided at the upper end of the converging pipe, and the output shaft of the second motor passes through the upper end of the converging pipe and is welded and fixed to the upper end of the stirring blade.

[0009] Preferably, a first support is provided on the outside of the converging pipe, and the first support is fixedly connected to the outside of the stirring frame and the second motor by bolts.

[0010] Preferably, a stirring paddle is vertically arranged in the middle of the inside of the stirring frame.

The second bracket is rotatably connected to the upper end of the stirring paddle, and the upper end of the second bracket is provided with a first motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In this invention, the electronic valve opens and discharges the material temporarily stored in the temporary storage tank. After the material in the two temporary storage tanks is transferred along the transmission pipe, the material in the transmission pipe can be gathered by the converging pipe and fall uniformly from the top of the stirring paddle, which can directly contact the stirring paddle used for agitation. During the process of the liquid material being gathered from inside the converging pipe, the stirring blade can be driven by the second motor and can rotate, so that the material gathered inside the converging pipe can be gathered by the stirring blade and temporarily mixed, which can increase the agitation efficiency of the stirring paddle position on the material and improve the efficiency of kraft paper preparation.

[0018] The present invention will be further described below with reference to specific embodiments.

[0019] like Figure 1 As shown, a quantitative pulping device for kraft paper preparation in this embodiment includes a stirring frame 1. A stirring paddle 6 is vertically arranged in the middle of the stirring frame 1. A second support 5 is arranged at the upper end of the stirring paddle 6, and the second support 5 is fixedly connected to the stirring frame 1 by bolts. The second support 5 is rotatably connected to the upper end of the stirring paddle 6. After the stirring paddle 6 is supported by the second support 5, the second support 5 can be rotatably installed on the surface of the stirring frame 1. The material inside the stirring frame 1 can be stirred by the suspended stirring paddle 6, thereby completing the quantitative pulping device for kraft paper preparation.

[0020] Furthermore, a first motor 7 is provided at the upper end of the second bracket 5, and the output shaft of the first motor 7 is fixedly connected to the circular position of the stirring paddle 6. The first motor 7 can actively output and drive the stirring paddle 6 to rotate.

[0021] To improve material mixing efficiency, a collecting pipe 12 is installed on one side of the upper end of the mixing frame 1, and temporary storage tanks 9 are installed on both sides of the upper end of the collecting pipe 12. Figure 3 As shown, a transmission pipe 11 is provided between the lower end of the temporary storage tank 9 and the converging pipe 12. The transmission pipe 11 and the converging pipe 12 are sealed together. The material to be quantitatively mixed is pre-poured and stored inside the temporary storage tank 9. The material discharged from the temporary storage tank 9 is transmitted through the transmission pipe 11 and then uniformly transmitted to the converging pipe 12. The material to be stirred can be pre-mixed before stirring and mixing, reducing the stirring time at the subsequent stirring paddle 6 position.

[0022] Furthermore, an electronic valve 10 is provided between the transfer pipe 11 and the temporary storage tank 9, and the temporary storage tank 9, the electronic valve 10 and the transfer pipe 11 are sequentially and sealed together. After the electronic valve 10 is opened, the material inside the temporary storage tank 9 is discharged along the transfer pipe 11 and finally converges into the inside of the convergence pipe 12.

[0023] It is worth mentioning that, such as Figure 2 As shown, a stirring blade 13 is vertically arranged inside the collecting pipe 12. The material discharged from the temporary storage tank 9 will gather in the collecting pipe 12 and come into contact with the rotatable stirring blade 13. The material discharged from the inside of the collecting pipe 12 can be temporarily mixed by the stirring blade 13.

[0024] In this embodiment, a second motor 8 is provided at the upper end of the converging pipe 12. The output shaft of the second motor 8 passes through the upper end of the converging pipe 12 and is welded and fixed to the upper end of the stirring plate 13. The output of the second motor 8 can actively drive the stirring plate 13 to rotate inside the converging pipe 12.

[0025] Furthermore, in order to support the converging pipe 12, a first support 4 is provided on the outside of the converging pipe 12, and the first support 4 is fixedly connected to the outside of the stirring frame 1 and the second motor 8 by bolts. The converging pipe 12, the second motor 8 and the temporary storage tank 9 can be supported by the first support 4.

[0026] In order to adapt to the quantitative pulping device for kraft paper preparation, a discharge pipe 3 is provided at the lower end of one side of the stirring frame 1, and an inlet pipe 2 is provided at the upper end of the other side of the stirring frame 1. The material that needs to be filled into the stirring frame 1 is put into the stirring frame 1 through the inlet pipe 2. When the material inside the stirring frame 1 is discharged, the material inside the stirring frame 1 is finally discharged from the discharge pipe 3.

[0027] Working principle: When using the device to quantitatively prepare kraft paper pulp, the liquid material required for pulp preparation is poured into the temporary storage tank 9. The electronic valve 10 is activated, and the material stored in the temporary storage tank 9 passes through the electronic valve 10 and is transferred by the transfer pipe 11. The material is then transferred by the transfer pipe 11 and finally converged at the converging pipe 12. At the same time, the liquid material converges into the converging pipe 12, and the stirring blade 13 is rotated by the second motor 8. The rotation of the stirring blade 13 can temporarily agitate and mix the liquid material discharged from the transfer pipe 11, so that the required material is uniformly collected by the converging pipe 12 and uniformly discharged from the lower end of the converging pipe 12. It falls from the upper end of the rotating position of the stirring paddle 6 and can be directly agitated by the stirring paddle 6 driven by the first motor 7. The agitation thus achieves the mixing of the material. The material stored in the temporary storage tank 9 is quantitatively discharged according to the calculated value, realizing efficient quantitative pulp preparation.
