Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, and in particular to a papermaking dry wire cleaning device. Background Technology

[0002] In the papermaking process, the dryer wire (also known as the drying wire) is an important component of the drying section of the paper machine. It carries wet paper sheets and dries them by heating with hot air or steam. Because the dryer wire is in prolonged contact with wet paper and hot air, paper scraps, resin, sizing agents, and other contaminants easily accumulate on its surface, affecting drying efficiency and paper quality. Existing dryer wire cleaning devices mostly use scrapers, brush rollers, or high-pressure water washing, but these still have the following drawbacks:

[0003] When using a scraper for cleaning, the mechanical cleaning method involving the scraper and brush roller can easily lead to wear on the surface of the papermaking web, shortening its service life. Scrapers and brush rollers are also ineffective at completely removing fine contaminants from the web surface, especially sticky substances such as resins and adhesives. While high-pressure water rinsing provides better cleaning, it consumes a large amount of water, resulting in water waste. Therefore, to address these shortcomings, this invention proposes a papermaking web cleaning device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a papermaking dry wire cleaning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a papermaking dry wire cleaning device, comprising a box body, wherein an inlet and an outlet are respectively provided on both sides of the box body; multiple bottom guide rollers are rotatably connected at equal distances to the bottom of the box body near the inlet side; multiple top guide rollers are rotatably connected at equal distances to the top of the box body near the inlet side; the multiple bottom guide rollers and multiple top guide rollers are arranged in an alternating manner; multiple airflow cleaning components are provided inside the box body between the bottom guide rollers and the top guide rollers; a high-pressure blower is installed on the upper surface of the box body, and an air outlet pipe is fixedly connected to the outlet of the high-pressure blower; a water tank is installed on the bottom wall of the box body, and an ultrasonic generator is installed at the bottom of the water tank; a drying component is installed inside the box body near the outlet; both the drying component and the airflow cleaning component are connected to the high-pressure blower; and two side doors are rotatably connected to one side of the box body via hinges.

[0006] Furthermore, the airflow cleaning component includes a horizontal pipe fixed inside the housing, a number of high-pressure jet nozzles fixed at equal intervals on the side wall of the horizontal pipe, the air outlet pipe being connected to the horizontal pipes of multiple airflow cleaning components through a pipe, and a dust guide hopper fixed on the bottom wall of the housing below the bottom guide roller.

[0007] Furthermore, a baffle is fixed inside the housing and below each top guide roller.

[0008] Furthermore, two side guide rollers are rotatably connected to both sides of the top of the pool, and two inner guide rollers are rotatably connected to both sides of the bottom of the pool.

[0009] Furthermore, two extrusion rollers are rotatably connected inside the box and near the discharge port.

[0010] Furthermore, a drain pipe is fixedly connected to the bottom of the pool, and a valve is installed on the drain pipe.

[0011] Furthermore, the drying assembly includes a vertical pipe that penetrates the top wall of the chamber, with a fan hood fixedly connected to the bottom end of the vertical pipe, the top end of the vertical pipe communicating with the air outlet pipe, and a heating tube fixedly connected to the middle of the vertical pipe, with an electric heating wire installed inside the heating tube.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, a papermaking dry wire cleaning device is disclosed, comprising a housing 1, with an inlet 101 and an outlet 102 on both sides of the housing 1. Multiple bottom guide rollers 2 are rotatably connected at equal intervals on the bottom side of the housing 1 near the inlet 101, and multiple top guide rollers 3 are rotatably connected at equal intervals on the top side of the housing 1 near the inlet 101. The bottom guide rollers 2 and top guide rollers 3 are arranged in an alternating pattern. Multiple airflow cleaning components 4 are provided inside the housing 1 between the bottom guide rollers 2 and top guide rollers 3. A high-pressure blower 5 is installed on the upper surface of the housing 1, and an outlet pipe 51 is fixedly connected to the outlet of the high-pressure blower 5. A water tank 8 is installed on the bottom wall of the housing 1, and an ultrasonic generator 9 is installed at the bottom of the water tank 8. A drying component 13 is installed inside the housing 1 near the outlet 102. Both the drying component 13 and the airflow cleaning components 4 are connected to the high-pressure blower 5. Two side doors 14 are rotatably connected to one side of the housing 1 via hinges.

[0024] The airflow cleaning component 4 includes a horizontal pipe 41 fixed inside the housing 1. Several high-pressure jet nozzles 42 are fixed at equal intervals on the side wall of the horizontal pipe 41. The air outlet pipe 51 is connected to the horizontal pipes 41 of the multiple airflow cleaning components 4 through a pipe. A dust guide hopper 7 is fixed on the bottom wall of the housing 1 and below the bottom guide roller 2.

[0025] After the high-pressure blower 5 is started, the airflow enters multiple horizontal pipes 41 along the air outlet pipe 51, and then is ejected from the high-pressure jet nozzle 42, using the high-speed airflow to clean the dry net wrapped between the bottom guide roller 2 and the top guide roller 3.

[0026] Inside the housing 1, a baffle 6 is fixed below each top guide roller 3.

[0027] By setting baffle 6, the dust blown off by the airflow cleaning component 4 can be prevented from falling back onto the dry net surface. Baffle 6 serves to separate multiple airflow cleaning components 4.

[0028] Two side guide rollers 10 are rotatably connected to the top two sides of the water tank 8, and two inner guide rollers 11 are rotatably connected to the bottom two sides of the water tank 8.

[0029] The side guide roller 10 and the inner guide roller 11 can guide the dry net, allowing it to pass through the bottom of the water tank 8, which facilitates further cleaning of the dry net by ultrasonic waves.

[0030] Two extrusion rollers 12 are rotatably connected inside the housing 1 and near the discharge port 102.

[0031] After being cleaned by ultrasonic waves, the dry net can pass between two squeezing rollers 12, which squeeze out the water on the surface of the dry net, thus facilitating the subsequent drying assembly 13 to quickly dry the dry net.

[0032] A drain pipe is fixedly connected to the bottom of the water tank 8, and a valve is installed on the drain pipe.

[0033] By opening the valve on the drain pipe, the water in pool 8 can be drained, making it easier to replace the water in pool 8.

[0034] The drying assembly 13 includes a vertical pipe 131 that penetrates the top wall of the chamber 1, and a fan hood 132 is fixedly connected to the bottom end of the vertical pipe 131. The top end of the vertical pipe 131 is connected to the air outlet pipe 51. A heating tube 133 is fixedly connected to the middle of the vertical pipe 131. An electric heating wire 134 is installed inside the heating tube 133.

[0035] After the high-pressure blower 5 is started, the airflow will be blown out from the hood 132 along the vertical pipe 131. During this process, the airflow will pass through the heating pipe 133 and be heated by the electric heating wire 134 inside the heating pipe 133, thereby forming hot air, which is used to dry the dry net.

[0036] Working principle: The dry mesh enters the housing 1 through the feed inlet 101, then passes sequentially around the top guide roller 3 and the bottom guide roller 2, followed by the side guide roller 10 and the inner guide roller 11, and finally passes between the two extrusion rollers 12 before exiting through the discharge outlet 102. At the start of cleaning, the dry mesh moves under the drive of the drive unit. At this time, the high-pressure blower 5, the ultrasonic generator 9, and the electric heating wire 134 are activated, causing the airflow cleaning component 4 to blow away the dust on the dry mesh. The dust falls into the dust guide hopper 7 and is discharged from the bottom of the hopper 7. The dry mesh then enters the water tank 8 and is cleaned again by ultrasonic waves. After cleaning, the dry mesh is squeezed by the two extrusion rollers 12, thus squeezing out the water. When the dry mesh passes under the air hood 132, it is dried by hot air.

[0037] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
