Description

Technical Field

[0001] The utility model relates to the technical field of pulp additives, in particular to a fluorine-free oil-proofing accelerator processing device for pulp production. Background Art

[0002] Pulp is a fibrous material made from plant fiber through different processing methods. Depending on the different derivative products, the performance requirements for pulp will also be different. Therefore, various additives are needed in the production process of pulp, and fluorine-free oil-proof accelerator is one of them to improve the waterproof, oil-proof and anti-fouling properties. Fluorine-free oil-proof accelerator also requires different ingredients during the processing process and is made by uniform stirring.

[0003] The traditional processing device of fluorine-free oil-proof accelerator directly pours all the proportioned ingredients into the mixing barrel, which is difficult to mix and makes stirring difficult. At the same time, after stirring, the mixture needs to be discharged first, and then the materials are added for a new round of stirring processing. Continuous processing is impossible, and the processing efficiency needs to be improved. Some existing continuous processing devices cannot control the addition of materials according to the stirring rate when continuously adding materials, which makes it easy to cause insufficient stirring and mixing, thereby reducing product quality. Utility Model Content

[0004] The purpose of the utility model is to solve the above-mentioned problems that directly pouring materials makes stirring difficult, continuous processing cannot be carried out, processing efficiency needs to be improved, and the addition of materials cannot be controlled according to the stirring rate, which easily leads to insufficient stirring and mixing. The utility model provides a fluorine-free oil-proof accelerator processing device for pulp production.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] A fluorine-free oil-proof accelerator processing device for pulp production comprises a stirring barrel, wherein the bottom of the stirring barrel is rotatably connected to a rotating shaft, a stirring blade is fixedly installed on the periphery of the middle part of the rotating shaft, two mounting plates are symmetrically fixedly installed on the upper part of the stirring barrel, a driven shaft is evenly rotatably connected between the upper and lower mounting plates, a driven wheel is fixedly installed on the bottom end of the driven shaft, a driving wheel is fixedly installed on the periphery of the top of the rotating shaft, a belt is drivingly connected between the driving wheel and the driven wheel, a lifting rod is slidably connected to the inside of the top of the driven shaft, a spring is fixedly connected between the bottom end of the lifting rod and the inner wall of the driven shaft, and the An upper hinge seat is fixedly installed on the periphery of the bottom of the lifting rod, and the upper hinge seat passes through the driven shaft outward. A sliding groove for the upper hinge seat to slide is opened in the middle of the driven shaft, and a lower hinge seat is fixedly installed on the periphery of the bottom of the driven shaft. A transmission rod is transmission-connected between the upper hinge seat and the lower hinge seat, and blades are transmission-connected on the outer side of the transmission rod. A conical block is fixedly installed on the top of the lifting rod, and a feeding pipe is fixedly installed on the top of the mixing barrel. The feeding pipe is aligned with the conical block and is located above the conical block. The bottom diameter of the conical block is matched with the aperture of the feeding pipe. When the conical block is fully extended into the feeding pipe, the bottom of the feeding pipe can be blocked.

[0007] Furthermore, the rotating shaft extends upward to the top of the lower mounting plate and is rotationally connected at a limited position in the center of the lower mounting plate to improve the stability of the rotating shaft.

[0008] Furthermore, the upper and lower symmetrical mounting plates are fixedly mounted to the inner wall of the mixing barrel by three support rods evenly distributed around the circumference. There are three driven shafts, which are respectively located between the centers of the three support rods of the upper and lower symmetrical mounting plates, so that the material can pass through the mounting plates, and the transmission rod and blades on the driven shaft are evenly distributed in the mixing barrel.

[0009] Furthermore, the driven shafts have different downward extension lengths, which causes height misalignment of the driven wheels at the bottom ends of different driven shafts, and the diameters of different driven wheels are different. There are three driving wheels in total, which are located below the lower mounting plate and evenly arranged up and down. The three driving wheels have the same diameter and are all connected to the driven wheels at the same height through belts. Therefore, under the action of the rotating shaft, the driven wheels and the driven shaft can be driven to rotate at different speeds.

[0010] Furthermore, the inner side transmission of a single blade is connected to two transmission rods, the other sides of the two transmission rods are extended to the upper and lower sides, and are respectively hinged to the upper hinge seat and the lower hinge seat, and the upper hinge seat, the lower hinge seat, the transmission rod and the blade are evenly distributed on the periphery of the driven shaft. Therefore, when the driven shaft rotates, the blade can move outward under the action of centrifugal force, and then pull the lifting rod downward under the action of the transmission rod.

[0011] Furthermore, a support seat is fixedly installed on the edge of the bottom of the mixing barrel extending downward, which is used to suspend the mixing barrel. A motor is fixedly installed in the center of the bottom end of the mixing barrel, which is used to drive the rotating shaft to rotate. A discharge pipe is fixedly installed on one side of the motor at the bottom end of the mixing barrel. The discharge pipe is connected to the inside of the mixing barrel and is used for outputting the mixed material.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. The utility model realizes the rotation of the driven shaft at different speeds by using the driving wheel of the same diameter to drive the driven wheels of different diameters when the rotating shaft rotates, and uses the centrifugal force to drive the lifting rod and the conical block to move downward when the driven shaft rotates, thereby realizing the different downward movement distances of the conical block relative to the feeding tube, thereby generating different feeding gaps, so as to realize the continuous addition of materials with different proportions, and there is no need to add them directly according to the proportion, which is convenient for mixing and reduces the difficulty of stirring. At the same time, it can also realize continuous stirring and mixing work, and improve the processing efficiency.

[0014] 2. The utility model controls the centrifugal force of the blades through the rotational speed. When the stirring speed changes, the overall rotational speed of the driven shaft changes accordingly. When the rotational speed increases, the feed will be increased. Conversely, when the rotational speed decreases, the feed will be reduced. This achieves the adjustment of the amount of material added according to the stirring rate, thereby ensuring the stirring effect and improving product quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0023] A fluorine-free oil-proofing accelerator processing device for pulp production according to a preferred embodiment of the utility model will be described in detail below. Figure 1-6 As shown, a fluorine-free oil-proof accelerator processing device for pulp production includes a stirring barrel 1, a rotating shaft 2 is rotatably connected to the bottom of the stirring barrel 1, a stirring blade 3 is fixedly installed on the periphery of the middle of the rotating shaft 2, two mounting plates 4 are symmetrically fixedly installed on the upper part of the stirring barrel 1, the rotating shaft 2 extends upward to the top of the lower mounting plate 4, and is rotatably connected to the center of the lower mounting plate 4 to improve the rotation stability of the rotating shaft 2.

[0024] A driven shaft 5 is evenly limited and rotatably connected between the upper and lower mounting plates 4. The upper and lower symmetrical mounting plates 4 are fixedly mounted to the inner wall of the mixing barrel 1 through three support rods evenly distributed on the circumference. There are three driven shafts 5, which are respectively located between the centers of the three support rods of the upper and lower symmetrical mounting plates 4, so that the material can pass through the mounting plates 4, and the transmission rod 13 and the blades 14 on the driven shaft 5 are evenly distributed in the mixing barrel 1. A driven wheel 6 is fixedly mounted on the bottom end of the driven shaft 5, and a driving wheel 7 is fixedly mounted on the periphery of the top of the rotating shaft 2. A belt 8 is transmission-connected between the driving wheel 7 and the driven wheel 6. The driven shaft 5 extends downward by different lengths, so that the driven wheels 6 at the bottom ends of different driven shafts 5 are height-displaced, and the diameters of different driven wheels 6 are different. There are three driving wheels 7, which are located below the lower mounting plate 4 and evenly arranged up and down. The three driving wheels 7 have the same diameter and are all transmission-connected to the driven wheels 6 at the same height through belts 8. Therefore, under the action of the rotating shaft 2, the driven wheel 6 and the driven shaft 5 can be driven to rotate at different speeds.

[0025] A lifting rod 9 is slidably connected to the inside of the top of the driven shaft 5, a spring 10 is fixedly connected between the bottom end of the lifting rod 9 and the inner wall of the driven shaft 5, an upper hinge seat 11 is fixedly installed on the periphery of the bottom of the lifting rod 9, the upper hinge seat 11 passes through the driven shaft 5 outward, and a slide groove for the upper hinge seat 11 to slide is opened in the middle of the driven shaft 5, a lower hinge seat 12 is fixedly installed on the periphery of the bottom of the driven shaft 5, a transmission rod 13 is transmission-connected between the upper hinge seat 11 and the lower hinge seat 12, and a blade 14 is transmission-connected to the outside of the transmission rod 13, a conical block 15 is fixedly installed on the top of the lifting rod 9, and a feeding pipe 16 is fixedly installed on the top of the mixing barrel 1, and the feeding pipe 16 is aligned with the conical block 15 and is located Above the conical block 15, the bottom diameter of the conical block 15 is adapted to the aperture of the feeding tube 16. When the conical block 15 is fully extended into the feeding tube 16, the bottom of the feeding tube 16 can be blocked. The inner side transmission of a single blade 14 is connected with two transmission rods 13. The other sides of the two transmission rods 13 are extended to the upper and lower sides, and are respectively hinged to the upper hinge seat 11 and the lower hinge seat 12. The upper hinge seat 11, the lower hinge seat 12, the transmission rod 13 and the blade 14 are evenly distributed on the periphery of the driven shaft 5. Therefore, when the driven shaft 5 rotates, the blade 14 can move outward under the action of centrifugal force, and then pull the lifting rod 9 downward under the action of the transmission rod 13.

[0026] A support seat 17 is fixedly installed on the edge of the bottom of the mixing barrel 1 to extend downward, and is used to suspend the mixing barrel 1. A motor 18 is fixedly installed in the center of the bottom end of the mixing barrel 1 to drive the rotating shaft 2 to rotate. A discharge pipe 19 is fixedly installed on one side of the motor 18 at the bottom end of the mixing barrel 1. The discharge pipe 19 is connected to the inside of the mixing barrel 1 and is used for outputting the mixed material.

[0027] The working principle of the utility model is:

[0028] Through different material ratios, the required materials are connected to the corresponding feeding pipes 16 through the transport tanks, and then during processing, the motor 18 is started to drive the rotating shaft 2 to rotate. During the rotation of the rotating shaft 2, the driven wheel 6 at the bottom end of the driven shaft 5 is connected by the belt 8, which can drive the driven wheel 6 and the driven shaft 5 to rotate. By designing that the driving wheel 7 has the same radius and the driven wheel 6 has different radius, the speed of driving the driven shaft 5 to rotate can be different.

[0029] During the rotation of the driven shaft 5, the transmission rod 13 and the blades 14 can be driven to rotate, thereby preliminarily stirring the incoming material. At the same time, during the rotation, the blades 14 will move outward under the action of centrifugal force, and then under the action of the transmission rod 13, the lifting rod 9 will be pulled to compress the spring 10 and move downward, thereby driving the conical block 15 to move downward, so that the conical block 15 can open the feeding pipe 16, so that the material can enter the mixing barrel 1 through the feeding pipe 16.

[0030] With the different rotation speeds of the driven shaft 5, the blades 14 move outward at different amplitudes under the action of centrifugal force, and thus the distances by which the lifting rod 9 and the conical block 15 are pulled downward will also be different. Through the cooperation of the conical block 15 and the feeding tube 16, the greater the downward distance, the larger the gap between the conical block 15 and the feeding tube 16, and the more material will be discharged, thereby achieving continuous addition of materials of different proportions to meet the continuous processing.

[0031] The proportioned materials are initially stirred by the transmission rod 13 and the blades 14, and then enter the mixing barrel 1. The rotating shaft 2 drives the stirring blades 3 to rotate and then fully mix them. After mixing, they are discharged through the discharge pipe 19 for the next processing.

[0032] When the rotation speed of the rotating shaft 2 changes, the driving wheel 7 drives the rotation speed of the driven wheel 6 and the driven shaft 5 as a whole to change accordingly. When the rotation speed increases, the rotation speed of all driven shafts 5 will increase, and then the blade 14 drives the lifting rod 9 and the conical block 15 to move downward through the transmission rod 13. The distance will also increase, which will increase the feed. On the contrary, when the rotation speed decreases, the feed will be reduced, thereby realizing the adjustment of the amount of material added according to the stirring rate.

[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
