Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust removal equipment technology, specifically a high-efficiency filtration plasma dust removal device. Background Technology
[0002] During the production and processing of tissue paper, its soft fiber surface is highly susceptible to the generation and adhesion of fine paper dust, fiber debris, and other contaminants due to friction. Simultaneously, the high-speed operation of the production line causes the paper to carry a strong static charge, resulting in these lightweight dust particles being firmly adhered to the paper surface. Failure to thoroughly clean these dust particles directly impacts the cleanliness, aesthetics, and user experience of the final product.
[0003] Currently, most dust removal methods for household paper products use pure negative pressure suction, which is effective for loose fiber debris on the surface of the paper, but less effective for fine paper dust attracted by electrostatic attraction. Increasing the suction power and fan power may cause soft paper to be partially lifted, resulting in wrinkles, deformation, or even being sucked into the pipes, leading to paper breaks and production interruptions. Soft brushes are also used to remove dust, but continuous physical contact inevitably rubs against the paper surface, becoming a new source of paper dust, leading to a vicious cycle of the cleaner the paper becomes dirtier.
[0004] Therefore, a high-efficiency plasma dust removal device is needed to improve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a high-efficiency plasma dust removal device for filtration, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-efficiency filtration plasma dust removal device includes: The mounting structure includes a set of mounting seats, two of which are fixedly mounted on the surface of the object to be mounted by bolts. A plasma dust removal assembly includes several dust removal pipes, which are limited and installed between two mounting bases. The dust removal pipes are arranged at intervals in the vertical direction, and a dust removal channel for paper to pass through is formed between adjacent dust removal pipes. The fan is connected to a manifold via a connecting pipe. The manifold is mated with the ends of several dust removal pipes. Under the action of the fan, air is drawn from the dust removal pipes to create negative pressure.
[0007] As a preferred embodiment of this utility model, the mounting base includes a vertical support, the lower end of which is connected to a base by bolts, a vertical mounting groove is opened on the side of the vertical support, a number of horizontal supports are installed in the vertical mounting groove, a number of horizontal adjustment grooves are opened on the horizontal supports, and each horizontal support has two limiting grooves at one end for the end of the dust removal pipe fitting to be inserted and installed.
[0008] As a preferred embodiment of this utility model, the dust removal pipe includes a pipe body, each pipe body has a strip groove on its side, and each pipe body has a high-voltage electrode inside, the high-voltage electrode being connected to an external power source.
[0009] As a preferred embodiment of this utility model, the strip groove is inclined to the vertical plane, and the inclined direction of the strip groove is towards the paper input direction.
[0010] As a preferred embodiment of this utility model, the tube body is made of ceramic material, and a conductive film is provided on the outer side of the tube body.
[0011] As a preferred embodiment of this utility model, one end of the manifold is provided with an output end for connecting to the connecting pipe, and the other end of the manifold is provided with a plurality of input ends for connecting to the end of the dust removal pipe fitting.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model solves the problem of poor removal effect of traditional pure negative pressure dust collection method on electrostatic adsorption of fine paper dust. By adopting non-contact plasma wind technology, the static charge on the paper surface is neutralized, the adsorption force of dust is broken down, and it is easy to detach. At the same time, combined with negative pressure dust collection, it can efficiently capture the loosened dust, achieve thorough removal of fine paper dust, and completely avoid the production risk of paper being sucked up, wrinkled or broken due to increased suction. 2. This utility model overcomes the problem of secondary pollution caused by mechanical contact dust removal. The entire dust removal process does not require physical contact with the paper surface, eliminating the possibility of generating new paper dust due to friction. The non-contact working mode improves the cleanliness of the product and ensures the continuity and stability of the production process. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0019] Please see Figure 1-3 This utility model provides a technical solution: For an example, please refer to... Figure 1 , 2 He 3, a high-efficiency filtration plasma dust removal device, mainly consists of three parts: installation structure, plasma dust removal components, and fan system.
[0020] The mounting structure is responsible for securely mounting the entire equipment onto the production line frame. It consists of a set of symmetrically arranged mounting seats, each of which includes a vertical support. The lower end of the vertical support 3 is fixedly connected to a base 9 by bolts, and the base 9 is securely mounted on a designated mounting surface of the production line, such as the crossbeam of the frame, by bolts. On the side of the vertical support 3, two parallel vertical mounting slots are provided. Multiple horizontal supports 4 are installed in these vertical mounting slots by adjustable fasteners, so that the vertical position of the horizontal supports 4 can be flexibly adjusted according to the paper path of the actual production line. Each horizontal support 4 also has a long horizontal adjustment slot 10 for fine-tuning its front and rear position. In particular, at the end of each horizontal support 4 facing the inside of the equipment, two semi-circular limiting slots 11 are machined. These two limiting slots 11 are used to precisely support and position the end of the plasma dust removal component.
[0021] The plasma dust removal component is the main structure, which consists of multiple hollow tubes 6 arranged in parallel. The two ends of these tubes 6 are respectively placed and confined in the limiting grooves 11 of the horizontal supports 4 on the left and right sides, so that they are stably suspended in the mounting frame. The multiple tubes 6 are arranged in parallel with a certain interval in the vertical direction, so that a dust removal channel is formed between two adjacent tubes 6, allowing paper to pass through horizontally. Household paper can pass through these layered dust removal channels in sequence for cleaning.
[0022] Each tube 6 is made of highly insulating ceramic material. A transparent conductive film is covered on the outer surface of the tube 6, which serves as the grounding electrode for generating plasma wind. Inside the tube 6, a high-voltage metal electrode 12 is inserted along its axial direction. The high-voltage electrode 12 is connected to an external CNC high-voltage power supply. On the side of the tube 6 facing the paper, multiple slender slots 7 are machined. These slots 7 are inclined at an acute angle to the vertical plane, and their inclination direction is consistent towards the input direction of the paper. When a high-frequency pulse voltage of several kilovolts is applied to the high-voltage electrode 12, the air in the strong electric field region at the edge of the slot 7 is ionized to form low-temperature plasma, thereby generating a continuous and uniform plasma wind.
[0023] Please refer to Figure 1 , 2 3. The fan system is responsible for providing stable negative pressure suction. The system includes a fan 1 as a power source. The air inlet of the fan 1 is connected to the output end of a manifold 2 through a connecting pipe 8. The manifold 2 has multiple input ends on its body, the number of which corresponds to the number of pipes 6. Each input end is connected to the end of a pipe 6 through a sealing structure. When the fan 1 is started, it continuously draws air from the manifold 2, thereby forming a stable negative pressure state inside all pipes 6 connected to the manifold 2. This negative pressure generates suction on the outside air through the strip groove 7.
[0024] Working principle: Household paper passes horizontally through the layered dust removal channels formed by multiple tubes 6 at a certain speed. Two systems start simultaneously: First, the high-voltage power supply supplies power to the high-voltage electrode 12 in each tube 6, generating plasma wind at the strip groove 7 and blowing it onto the paper surface. Second, the fan 1 starts working, forming a negative pressure inside all tubes 6.
[0025] The plasma wind first acts on the paper surface, neutralizing the static charge generated by the paper due to high-speed operation, fundamentally breaking down the electrostatic attraction between fine paper dust and paper fibers. The micro-airflow accompanying the plasma wind gently impacts the paper surface, causing the neutralized dust to loosen and rise. Since the strip groove 7 is inclined towards the direction of paper feeding, the negative pressure inside the tube body 6 due to the air extraction by the fan generates a suction force through the same strip groove 7. This suction force can accurately capture the dust loosened and constrained near the groove opening by the plasma wind and draw it into the tube body 6. The air containing a large amount of dust converges in the manifold 2 and is extracted by the fan 1 through the connecting pipe 8.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
