Description

Technical Field

[0001] This utility model relates to a device for cleaning stainless steel filter screens on high-speed trains, specifically a laser cleaning device and a cleaning machine. Background Technology

[0002] Due to long-term use, stainless steel mesh used on high-speed trains often accumulates debris, including dust, particles, and lint.

[0003] Filter specifications generally include the following:

[0004] A: Length × Width × Height: 640mm × 400mm × 18mm, Weight: 1.39kg;

[0005] B: Length × Width × Height: 460mm × 440mm × 20mm, Weight: 1.66kg;

[0006] C: Length × Width × Height: 755mm × 310mm × 18mm, Weight: 1.67kg.

[0007] Because of the different filter specifications, there is no universal fully automatic machine that can simultaneously clean and remove lint during cleaning. Therefore, existing technologies often rely on manual cleaning, which is labor-intensive and inefficient.

[0008] To address the aforementioned issues, the applicant previously proposed the technical solution CN2024202696810, which involved a streamlined cleaning process for the filter screen using a transportation mechanism in conjunction with roller brushes and water rinsing. However, actual use revealed that some contaminants remained difficult to remove. Therefore, further improvements were proposed, considering a high-temperature laser-based impurity removal solution. This requires design consideration. Utility Model Content

[0009] To address the issue of adding laser cleaning solutions to filter cleaning machines, this utility model provides a laser cleaning device and a cleaning machine.

[0010] The purpose of this utility model is achieved in the following manner: a laser cleaning device includes a housing 1 with an opening at the bottom and at least one ash discharge port 121 on the housing 1. A laser generator 2 is fixedly connected to the housing 1, and the output end of the laser generator 2 is arranged facing the opening at the bottom of the housing 1.

[0011] Furthermore, the housing 1 includes a door-shaped bracket 11, with a light-transmitting strip hole 111 at the top of the door-shaped bracket 11. A laser generator 2 is fixedly connected to the top of the door-shaped bracket 11, and the output end of the laser generator 2 cooperates with the light-transmitting strip hole 111. Sealing plates 12 are fixedly connected to the front and rear sides of the door-shaped bracket 11 to form a seal. A ash discharge port 121 is provided on the sealing plate 12, and an upward flow guiding structure is provided at the ash discharge port 121.

[0012] Furthermore, the sealing plate 12 is provided with ash discharge ports 121 at intervals along the vertical direction, and the ash discharge ports 121 are horizontal strip-shaped holes.

[0013] Furthermore, the flow guiding structure is a first flow guiding plate 122, which extends outward and upward from the bottom of the ash discharge port 121, and the cross-section of the first flow guiding plate 122 is straight or arc-shaped.

[0014] Furthermore, the front and rear ends of the top of the gate-shaped bracket 11 extend downward and inward respectively into the second guide plate 13, and a light-passing gap is formed between the bottoms of the two second guide plates 13, the light-passing gap being less than or equal to 40mm.

[0015] A cleaning machine including the above-mentioned laser cleaning equipment includes a conveying mechanism 3, on which a roller brush cleaning unit 31 is provided, and a laser cleaning device is provided behind the roller brush cleaning unit 31 along the conveying direction of the conveying mechanism 3.

Detailed Implementation

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] As attached Figure 1-2 As shown, a laser cleaning device includes a housing 1 with an opening at the bottom, through which the material to be cleaned passes. The housing 1 is provided with at least one ash discharge port 121. Since the working environment of this laser cleaning device is in a relatively enclosed cleaning machine, the housing 1 is used to prevent dust from scattering, and the ash discharge port 121 is used to discharge the dust uniformly. A laser generator 2 is fixedly connected to the housing 1. The laser generator is existing technology and emits high-energy lasers to carbonize the impurities on the filter screen surface to achieve the impurity removal effect. The output end of the laser generator 2 is set towards the opening at the bottom of the housing 1.

[0026] Furthermore, the housing 1 includes a door-shaped bracket 11, which can be formed by bending both sides of a long horizontal plate downwards. A light-transmitting strip hole 111 is provided at the top of the door-shaped bracket 11. A laser generator 2 is fixedly connected to the top of the door-shaped bracket 11. The output end of the laser generator 2 cooperates with the light-transmitting strip hole 111. Preferably, the output end of the laser generator 2 is located directly above the light-transmitting strip hole 111. Sealing plates 12 are fixedly connected to the openings on the front and rear sides of the door-shaped bracket 11 to block both sides respectively. A ash discharge port 121 is provided on the sealing plate 12, and an upward guiding structure is provided at the ash discharge port 121.

[0027] Furthermore, the sealing plate 12 is provided with ash discharge ports 121 at intervals along the vertical direction, and the ash discharge ports 121 are horizontal strip-shaped holes.

[0028] Furthermore, the flow guiding structure is a first flow guiding plate 122, which extends from the bottom of the ash discharge port 121 to the outside of the box 1 and upwards. The cross-section of the first flow guiding plate 122 is straight or arc-shaped.

[0029] Furthermore, the front and rear ends of the top of the gate-shaped bracket 11 extend downwards and inwards towards the inside of the housing 1, respectively, forming a light-passing gap between the bottoms of the two second guide plates 13. The second guide plates 13 reduce the amount of dust that drifts upwards to the output end of the laser generator 2. The light-passing gap is less than or equal to 40mm (and greater than the width of the laser output by the laser generator 2). The output end of the laser generator 2, the light-transmitting hole 111, and the light-passing gap are on the same spatial plane, so that the high-energy laser emitted from the output end of the laser generator 2 passes through the light-transmitting hole 111 and the light-passing gap in sequence to reach the filter screen to be cleaned at the opening below the housing 1.

[0030] Furthermore, a cleaning machine including the aforementioned laser cleaning equipment is described in CN2024202696810. This application adds the laser cleaning equipment described in this utility model to the existing cleaning machine, without modifying other components. It includes a conveying mechanism 3, which can be a belt conveyor or a chain conveyor. A roller brush cleaning unit 31 is provided on the conveying mechanism 3. The roller brush cleaning unit 31 already exists in the original design and will not be described again here. The laser cleaning equipment is located behind the roller brush cleaning unit 31 along the conveying direction of the conveying mechanism 3. The water cleaning equipment and high-pressure air blowing mechanism in the original design are both located after the laser cleaning equipment. A transverse support leg 14 is fixedly connected to the side of the housing 1 of the laser cleaning equipment. The support leg 14 is fixedly connected to... The frame of the conveying mechanism 3 is connected to the housing 1. A laser identification device 4 is installed on the top of the housing 1. The output end of the laser identification device 4 is oriented towards the opening at the bottom of the housing 1. The laser generator 2 is preferably two as shown in the figure. The laser emitted by the output end of the laser identification device 4 passes through the light-transmitting strip hole 111 and the light gap between the two laser generators 2 to reach the filter screen to be cleaned at the bottom opening of the housing 1. This is used to detect whether the filter screen to be cleaned is in place. Preferably, the laser emitted by the output end of the laser identification device 4 is parallel to the laser emitted by the output end of the laser generator 2. A suction device 5 is installed on the top of the housing 1. Both the laser identification device 4 and the suction device 5 are fixed on the housing of the entire cleaning machine. The laser identification device 4 and the suction device 5 are mentioned in the original scheme. Their structure and usage will not be described here.

[0031] The working process of this utility model is as follows: The filter screen to be cleaned is conveyed by the conveying mechanism 3, and is first initially cleaned by the roller brush cleaning unit 31. Then it passes through the laser cleaning equipment. After the head end of the filter screen is detected by the laser recognition device 4, the laser generator 2 starts to work. The high-energy laser is used to carbonize and remove impurities from the surface of the filter screen at high temperature. With the help of the top suction device 5, the dust is sucked upward. The second guide plate 13 reduces the intrusion of the output end of the laser generator 2 and the output end of the laser recognition device 4. The first guide plate 122 guides the dust to the direction of the upward suction device 5.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
