Description

Technical Field

[0001] This utility model relates to the technical field of bundled carbon fiber production equipment, and in particular to a cleaning device for a sizing tank of bundled short-cut carbon fiber. Background Technology

[0002] In the production process of bundled chopped carbon fibers, the fibers need to be sized in a sizing tank to improve their bonding performance with the matrix material. After a period of use, sizing residue will accumulate on the inner wall and bottom of the sizing tank. If it is not cleaned thoroughly in time, the following problems will occur after drying and solidification: (1) it will affect the purity of the subsequent sizing agent and the sizing quality; (2) the hard residue may scratch or wear the carbon fibers during fiber operation, producing fuzz or even broken fibers; (3) it will bring hidden dangers to the continuous and stable operation of the production equipment and increase unplanned downtime.

[0003] Currently, cleaning of sizing tanks mainly relies on manual operation, requiring workers to use tools to manually scrub and rinse with large amounts of water. This method is labor-intensive, has low cleaning efficiency, high water consumption, and is difficult to clean thoroughly, especially in blind spots such as corners of the tank. It has become a pain point affecting production efficiency and product quality.

[0004] Therefore, it is of great significance to study a cleaning device for the sizing tank of bundled short-cut carbon fibers to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a cleaning device for a sizing tank of bundled short-cut carbon fibers, which solves one or more of the problems mentioned above in the prior art.

[0006] This utility model provides a cleaning device for a sizing tank of bundled short-cut carbon fibers, comprising:

[0007] The sizing tank body has an inclined bottom, and a cleaning liquid outlet is provided at the lowest point of the inclined bottom.

[0008] A cleaning system, comprising a liquid cleaning pipeline, a gas cleaning pipeline, and an annular flushing pipeline;

[0009] The guide roller includes a fixed guide roller A, a fixed guide roller B, and a movable guide roller.

[0010] In some embodiments, a ball valve C is provided on the cleaning fluid outlet for controlling the discharge switch.

[0011] In some embodiments, the liquid cleaning line is equipped with a ball valve A, which is externally connected to a high-pressure water pipe.

[0012] In some embodiments, the gas cleaning line is equipped with a ball valve B, which is externally connected to a high-pressure gas line.

[0013] In some embodiments, the flushing pipe is fixed around the top inner side of the slurry tank, and its pipe wall is evenly provided with a number of flushing holes facing the inner wall and interior of the tank.

[0014] In some embodiments, the diameter of the flushing holes is 1 to 3 mm, and the spacing between the holes is 50 to 150 mm.

[0015] In some implementations, the angle between the inclined bottom and the horizontal plane is 5 to 15° to ensure that the cleaning waste liquid can be completely collected and quickly discharged.

[0016] In some implementations, the cleaning fluid outlet is connected to a wastewater recycling and treatment system via a pipeline.

[0017] In some embodiments, the movable guide roller is fixedly connected to the sizing tank body by bolts, which facilitates position adjustment and disassembly for cleaning.

[0018] The beneficial effects of this utility model are as follows:

[0019] (1) Through the surrounding multi-hole flushing pipes, the inner wall and bottom of the tank can be flushed from multiple angles at the same time without dead angles, replacing the tedious and inefficient manual cleaning, and the cleaning effect is significantly improved.

[0020] (2) The process of high-pressure water rinsing followed by high-pressure air purging is adopted; high-pressure water can effectively wash away most of the slurry residue; high-pressure gas is then introduced, which can blow off residual water droplets, dry the tank and avoid water stains, and further remove stubborn residues by using gas power; compared with the traditional method of simply rinsing with water, the consumption of clean water is greatly reduced.

Detailed Implementation

[0024] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0025] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0026] like Figure 1-2 As shown, a sizing tank cleaning device for bundled short-cut carbon fibers includes: a sizing tank body 1, a cleaning system, and a guide roller.

[0027] The bottom of the sizing tank 1 has an inclined bottom 8, and a cleaning liquid outlet 6 is provided at the lowest point of the inclined bottom 8. A ball valve C7 is provided on the cleaning liquid outlet 6 to control the discharge switch. The angle between the inclined bottom 8 and the horizontal plane is 5° to 15°. The cleaning liquid outlet 6 is connected to the wastewater recycling and treatment system through a pipeline.

[0028] The cleaning system includes a liquid cleaning pipeline 2, a gas cleaning pipeline 4, and a ring-shaped flushing pipe 9. The liquid cleaning pipeline 2 is equipped with a ball valve A3 and is externally connected to a high-pressure water pipe.

[0030] Specific operating steps: After the production of bundled short-cut carbon fiber is completed, the sizing tank 1 needs to be cleaned. First, open ball valve C7 to drain the remaining sizing agent through the cleaning liquid outlet 6; then open ball valve A3 and use high-pressure water from the liquid cleaning pipeline 2 to flush the tank through the flushing holes 10 on the flushing pipeline 9. The high-pressure water will flush the inner wall and bottom of the tank from multiple angles without dead angles; after cleaning, close ball valve A3, then open ball valve B5 to introduce high-pressure gas to blow away residual water droplets and further remove stubborn residues; after drying, close ball valves B5 and C7 to complete the cleaning process. The sizing agent can then be replaced or production can be stopped to ensure that the sizing tank is clean and free of contamination for the next production run.

[0031] In summary, the cleaning device for the sizing tank of bundled short-cut carbon fibers provided by this utility model has the following advantages:

[0032] (1) Through the surrounding multi-hole flushing pipes, the inner wall and bottom of the tank can be flushed from multiple angles at the same time without dead angles, replacing the tedious and inefficient manual cleaning, and the cleaning effect is significantly improved.
