[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0025] For example, please refer to the attached Figure 1-4 A pretreatment device for cellulose fiber manufacturing includes a mixing barrel 10, a support frame 40 is installed on the outside of the mixing barrel 10, a controller 50 is installed on one side of the support frame 40, a treatment liquid quantitative injection mechanism 20 is installed on one side of the mixing barrel 10, and the treatment liquid quantitative injection mechanism 20 includes a storage tank 21, and a liquid level sensor 22 and a water pump 23 installed on the top of the storage tank 21, the detection rod of the liquid level sensor 22 passes through the bottom of the storage tank 21, and the water pump 23 is connected to a delivery pipe 24, one end of the delivery pipe 24 passes through the bottom of the storage tank 21, and the other end passes through the top of the mixing barrel 10;

[0026] A cellulose raw material quantitative injection mechanism 30 is installed on the top of the support frame plate 40, and the cellulose raw material quantitative injection mechanism 30 includes a storage box 31 installed on the top of the support frame plate 40, and a discharge pipe 32 installed at the bottom of the storage box 31, and two hanging weighing devices 34 installed on the support frame plate 40 on both sides of the discharge pipe 32. The bottom of the two hanging weighing devices 34 is connected to a weighing cylinder 35, a first solenoid valve 33 is installed on the discharge pipe 32, and a second solenoid valve 36 is installed at the bottom of the weighing cylinder 35. A slot is provided at the top of the mixing barrel 10 at the bottom of the weighing cylinder 35.

[0027] It should also be noted that the electrical components of the device are all electrically connected to the controller 50, and the controller 50 is a conventional PLC controller.

[0028] For details, please refer to the attached Figure 2 The inner bottom of the storage box 31 is a slope structure inclined toward the discharge pipe 32, and the bottom of the weighing cylinder 35 is a funnel-shaped structure;

[0029] In this embodiment, it should be noted that the inner wall of the sloped structure facilitates the discharge of the cellulose raw material in the storage box 31 from the discharge pipe 32. Similarly, the weighing cylinder 35 at the bottom of the funnel-shaped structure facilitates the discharge of the raw material from the weighing cylinder 35, thereby preventing it from being left inside and affecting the discharge and weighing calculation results.

[0030] For details, please refer to the attached Figure 2 The top of the storage box 31 is provided with an opening, a sealing cover 37 is installed at the top opening of the storage box 31, and a handle is provided on the sealing cover 37;

[0031] In this embodiment, it should be noted that the sealing cover 37 can prevent foreign matter and dust from falling into the storage box 31 and causing pollution to the cellulose raw material, and the handle facilitates opening the sealing cover 37 .

[0032] For details, please refer to the attached Figure 2 , a transparent strip-shaped acrylic plate 38 is provided on one side of the storage box 31;

[0033] In this embodiment, it should be noted that the transparent strip-shaped acrylic plate 38 facilitates observation of the amount of remaining cellulose raw material inside the storage box 31 and facilitates timely addition.

[0034] For details, please refer to the attached Figure 3 The top of the storage tank 21 is provided with a liquid injection port 25, and the top of the storage tank 21 is installed with an audible and visual prompter 26;

[0035] In this embodiment, it should be noted that a minimum liquid level threshold is set in the controller 50. When the liquid level sensor 22 detects that the liquid level reaches the minimum liquid level threshold, the controller 50 operates the sound and light prompter 26, thereby prompting the staff to add processing liquid, so that the function of the liquid level sensor 22 is increased.

[0036] For details, please refer to the attached Figure 2 The top opening diameter of the weighing cylinder 35 is 2 cm larger than the outer diameter of the discharge pipe 32, and the inner diameter of the slotted hole at the top of the mixing barrel 10 is 2 cm larger than the outer diameter of the bottom opening of the weighing cylinder 35;

[0037] In this embodiment, it should be noted that the weighing cylinder 35 does not contact the discharge tube 32, and the weighing cylinder 35 does not contact the mixing barrel 10, which ensures the weighing accuracy. At the same time, the gap between adjacent ones is small to prevent foreign matter from falling into the mixing barrel 10 and affecting the pretreatment of cellulose fibers.

[0038] For details, please refer to the attached Figure 4 A stirring mechanism 60 is installed on the top of the mixing barrel 10, and the stirring mechanism 60 includes a driving motor 61 installed on the top of the mixing barrel 10, a rotating shaft 62 connected to the driving motor 61, and a plurality of stirring rods 63 distributed circumferentially on the rotating shaft 62;

[0039] In this embodiment, it should be noted that the operation of the driving motor 61 can realize the rotation of the rotating shaft 62 and the plurality of stirring rods 63, thereby achieving stirring of the raw material and the processing liquid.

[0040] The specific operation mode of the utility model is as follows:

[0041] When pre-treating cellulose fibers, the treatment liquid can be injected into the storage tank 21 in advance, the cellulose raw material can be injected into the storage box 31, and the required amount of cellulose raw material and treatment liquid can be input into the controller 50. Then, the water pump 23 is operated to input the treatment liquid into the mixing barrel 10 through the delivery pipe 24. At the same time, the liquid level sensor 22 detects the liquid level change in real time. The controller 50 calculates the amount of treatment liquid injected based on the volume and liquid level of the storage tank 21. After the fixed amount of treatment liquid is delivered, the water pump 23 stops operating.

[0042] At the same time, the first solenoid valve 33 opens, allowing the cellulose raw material to be injected into the weighing cylinder 35 through the discharge pipe 32. The two hanging scales 34 detect the weight change of the weighing cylinder 35. When the sum of the two weights reaches the set value, the first solenoid valve 33 closes and the second solenoid valve 36 opens, allowing the cellulose raw material to be injected into the mixing barrel 10.

[0043] Then, the stirring mechanism 60 is operated. By driving the motor 61 , the rotation shaft 62 and the plurality of stirring rods 63 can be rotated, thereby stirring the raw material and the processing liquid.

[0044] The above description of the present invention is illustrative in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
