Description

Technical Field

[0001] This utility model relates to the field of conveying mechanism technology, and in particular to a pulp conveying mechanism between the cotton pulp pretreatment and bleaching processes. Background Technology

[0002] Because refined cotton pulp is fibrous and has a certain degree of adhesion, it is prone to causing blockages in pipelines during transportation. After prolonged transportation, a layer of clumps can easily adhere to the inner wall of the pipeline, which will not only cause blockages but also reduce the flow rate of the pipeline over time.

[0003] In the prior art, such as the refined cotton slurry conveying pipe disclosed in Chinese Publication No. CN217234690U, a pipe body, an inner metal ring, a hanging ring, and an outer magnetic ring are included. The inner metal ring is slidably connected to the inner side of the pipe body, and symmetrical ring wall limiting grooves are arranged on both sides of the inner metal ring. A scraper ring is located inside the ring wall limiting grooves, and an outer magnetic ring is slidably connected to the outer side of the pipe body. In this invention, after the motor drives the scraper ring to rotate, the outer magnetic ring drives the inner metal ring to move along the pipe body, facilitating the cleaning of the inner wall of the pipe body. The pressurization pipe injects air into the inside of the pipe body through the air outlet pipe, pressurizing the inside of the pipe body and increasing the conveying speed of the slurry.

[0004] The above-mentioned technology has achieved the effect of allowing multiple people to use it simultaneously, but there are still some shortcomings, specifically: Traditional pulp conveying methods often employ open trenches or simple pumping systems, which are ill-suited to the high fiber content of cotton pulp. Due to the lack of forced mixing devices, pulp is prone to segregation during transport, resulting in uneven solid-liquid phase distribution. This directly affects the consistency of subsequent bleaching reactions. Single-stage straight-through conveying paths are prone to forming flow dead zones, especially at bends or diameter changes where frequent wall accumulation occurs, requiring frequent manual cleaning and significantly increasing operation and maintenance costs. Utility Model Content

[0005] The pulp conveying mechanism proposed in this utility model between the cotton pulp pretreatment and bleaching processes improves the continuity and uniformity of pulp conveying. The stirring blades dynamically mix the feed, effectively avoiding fiber flocculation and sedimentation, ensuring stable pulp concentration. The gradual pushing action formed by the conveying blades and the inner wall of the pipe can adapt to pulp media of different viscosities, reducing the risk of blockage. The symmetrically distributed support plates combined with the trough transmission structure make the whole machine run smoothly and have a significant noise reduction effect, while extending the service life of the conveying components, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pulp conveying mechanism between the cotton pulp pretreatment and bleaching processes, comprising a base, a support plate fixedly installed at the top of the base, a pipe fixedly installed at the top of the support plate, a discharge pipe installed on the left side of the pipe, a motor installed on the right side of the pipe, a conveying rod and a conveying blade installed at the output end of the motor, a feed pipe and a feeding hopper installed at the top right end of the pipe, a motor installed on the surface of the feed pipe, and a stirring rod and a stirring blade installed at the output end of the motor.

[0007] Preferably, the support plates are symmetrically distributed at the top of the base, and the pipe is fixed to the top of the base by the support plates.

[0008] Preferably, the bottom end of the discharge pipe is provided with a discharge port, the conveying rod rotates inside the pipe through a rotating groove, and the conveying blade is rotatably connected to the pipe.

[0009] Preferably, the stirring rod rotates inside the feed pipe via a rotating groove, the stirring blades are evenly distributed on the surface of the stirring rod, and the stirring blades are rotatably connected to the feed pipe.

[0010] Preferably, a limiting plate is fixedly installed at the top of the feeding hopper, a hinge is provided at the top of the limiting plate, a cover plate is fixedly installed at the top of the hinge, and a handle is fixedly installed at the top of the cover plate.

[0011] Preferably, the hinges are symmetrically distributed at the front and rear ends of the top of the limiting plate, and the cover plate is rotatably connected to the limiting plate through the hinges.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the discharge pipe, discharge port, rotating trough, motor, conveying rod, conveying auger, feed pipe, rotating trough, motor, stirring rod, stirring blade and feeding hopper improve the continuity and uniformity of slurry conveying. The stirring blade dynamically mixes the feed, effectively avoiding fiber flocculation and sedimentation, ensuring stable slurry concentration. The gradual pushing action formed by the conveying auger and the inner wall of the pipe can adapt to slurry media of different viscosities, reducing the risk of material blockage. The symmetrically distributed support plates combined with the rotating trough transmission structure make the whole machine run smoothly and have outstanding noise reduction effect, while extending the service life of the conveying components. 2. In this utility model, the limiting plate, hinge, cover plate, and handle improve the controllability of the feeding process and the adaptability to the working environment. The linkage design of the cover plate and the limiting plate forms an effective sealing barrier, which can prevent slurry splashing and external impurities from entering, reducing the risk of dust pollution in the production environment. The symmetrical distribution of the hinges makes the opening and closing of the cover plate flexible and labor-saving. Combined with the handle, it can achieve quick positioning and reset, shorten the feeding preparation time and reduce labor intensity. It prevents the slurry from evaporating moisture or changing temperature due to exposure, ensures the stability of the process parameters of the pretreated slurry, and provides a more uniform raw material base for the subsequent bleaching process.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1: As Figures 1-3 , Figure 5 , Figure 6 As shown, this utility model provides a technical solution: a pulp conveying mechanism between the cotton pulp pretreatment and bleaching processes, including a base 1, a support plate 2 fixedly installed at the top of the base 1, a pipe 3 fixedly installed at the top of the support plate 2, a discharge pipe 4 installed on the left side of the pipe 3, a motor 7 installed on the right side of the pipe 3, a conveying rod 8 and a conveying blade 9 installed at the output end of the motor 7, a feed pipe 10 and a feeding hopper 15 installed at the top right end of the pipe 3, a motor 12 installed on the surface of the feed pipe 10, a stirring rod 13 and a stirring blade 14 installed at the output end of the motor 12, the support plate 2 symmetrically distributed at the top of the base 1, the pipe 3 fixed to the top of the base 1 by the support plate 2, a discharge port 5 opened at the bottom end of the discharge pipe 4, the conveying rod 8 rotates inside the pipe 3 through a rotating groove 6, the conveying blade 9 is rotatably connected to the pipe 3, the stirring rod 13 rotates inside the feed pipe 10 through a rotating groove 11, the stirring blade 14 is evenly distributed on the surface of the stirring rod 13, and the stirring blade 14 is rotatably connected to the feed pipe 10.

[0018] In this embodiment, a double support plate 2 is used to stably support the pipeline 3. The conveying rod 8 and the agitator blade driven by the motor 7 achieve efficient and continuous material conveying. A feeding hopper 15 with a stirring function is added to the feeding end. The stirring rod 13 and the evenly distributed stirring blades 14 are driven by the motor 12 to effectively prevent the pulp from settling and clumping. The rotating structure of the trough 6 and the sealed rotating connection design ensure the stability of operation. At the same time, the discharge port 5 precisely controls the flow rate. It integrates homogenized conveying, anti-clogging design and modular layout, which significantly improves the efficiency and process stability of the pulp conveying process, reduces the equipment failure rate, and has a compact structure that is easy to maintain. It is especially suitable for cotton pulp production processes that are sensitive to fiber damage.

[0019] Example 2: As Figures 1-4 As shown, a limiting plate 16 is fixedly installed at the top of the feeding hopper 15. A hinge 17 is provided at the top of the limiting plate 16. A cover plate 18 is fixedly installed at the top of the hinge 17. A handle 19 is fixedly installed at the top of the cover plate 18. The hinges 17 are symmetrically distributed at the front and rear ends of the top of the limiting plate 16. The cover plate 18 is rotatably connected to the limiting plate 16 through the hinges 17.

[0020] In this embodiment, an effective protective barrier is formed by setting a flip-up cover 18 with hinges 17 and a limiting plate 16 to prevent pulp splashing and the ingress of external impurities. The symmetrically distributed hinges 17 ensure that the cover 18 can be opened and closed flexibly and stably. The handle 19 is designed for easy manual operation and quick loading and unloading. The limiting plate 16 precisely limits the range of motion of the cover 18 to avoid safety hazards caused by excessive opening. This structure combines sealing protection, convenient operation and operational reliability, effectively improving the cleanliness and efficiency of the feeding process and reducing the risk of material loss. It is especially suitable for cotton pulp production process environments with high purity requirements.

[0021] The working principle of this embodiment is as follows: When using, first place the base 1 in the required position so that the support plate 2 can firmly support the pipe 3. Then, hold the handle 19 and pull it upward so that the cover plate 18 can rotate upward at the top of the limiting plate 16 via the hinge 17. When the cover plate 18 is fully opened at the top of the limiting plate 16 via the hinge 17, the raw material is poured into the inside of the feeding hopper 15. Then, start the motor 12 on the surface of the feeding pipe 10 so that the stirring rod 13 drives the stirring blade 14 to rotate inside the feeding pipe 10 via the rotating groove 11, thereby avoiding the raw material from being blocked inside the feeding pipe 10. Then, start the motor 7 on the right side of the pipe 3 so that the conveying rod 8 drives the conveying blade 9 to rotate inside the pipe 3 via the rotating groove 6, so that it moves the raw material to the left and discharges it through the discharge port 5 into the inside of the discharge pipe 4. This structure can perfectly avoid the raw material from being blocked inside the pipe 3 during use.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
