Description

Technical Field

[0001] The utility model relates to the technical field of industrial dust removal and static electricity removal, in particular to an ion air knife cleaning device. Background Art

[0002] With the rapid development of modern industrial technology, especially in industries such as electronic manufacturing, precision machining, chemical engineering, and medicine, the problem of static electricity has become increasingly prominent and has become one of the key factors affecting product quality, production safety, and production efficiency. Static electricity, as a charge that temporarily stays on the surface of an object macroscopically, although seemingly in a static state, its potential hazards cannot be ignored. In the field of electronic production and processing, electrostatic discharge (ESD) may directly damage electronic components and affect the product yield rate; in flammable and explosive production sites, static electricity sparks may even trigger fires or explosions, seriously threatening the safety of personnel's lives and property.

[0003] Currently, the industrial community generally adopts various static electricity elimination technologies to address this problem. Among them, the air knife type static electricity eliminator (ion air knife) is favored because of its high efficiency and convenience. The ion air knife generates positive and negative ions through high-voltage ionization and, combined with the action of a high-speed air flow (the air curtain blown by the air knife), transports the ions to the surface of the object to be processed, effectively neutralizing and eliminating static electricity. However, although the ion air knife technology has been widely applied, it still faces many challenges and deficiencies in the actual application process.

[0004] First of all, the traditional ion air knife has obvious shortcomings in the ion utilization efficiency. Due to the limited natural diffusion distance of ions in the air (usually not exceeding 3 cm), combined with factors such as uneven air flow distribution and ion concentration attenuation, the utilization rate of ions before reaching the surface of the target object is relatively low, thus affecting the overall static electricity elimination effect. This not only increases energy consumption but also limits the applicability of the device in complex production environments.

[0005] Secondly, the design of existing ion air knives often focuses too much on the differences in volume size and ignores the importance of internal structure optimization and technological innovation. The requirements for static electricity elimination in different production environments vary, and there is a lack of customized products on the market that can flexibly adapt to the needs of various working conditions, making it difficult to meet the diverse needs of the industry.

[0006] In summary, in view of the deficiencies of the existing ion air knife technology, there is an urgent need for a new type of ion air knife device that can improve the ion utilization efficiency and enhance the static electricity elimination effect. This patent aims to solve the above problems through innovative structural design and technical solutions, providing a more efficient and reliable static electricity elimination solution for industrial production.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0030] The purpose of the present invention is to provide an ion air knife cleaning device to solve the problems existing in the prior art. By forming a concave space for accommodating the ion bar, the ions generated by the ion bar are gathered in the concave space and then carried by the air flow at the air outlet to the surface to be cleaned, which can improve the ion utilization efficiency and enhance the anti-static effect.

[0031] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation modes.

[0032] Such as Figures 1 to 3As shown in the figure, the utility model provides an ion air knife cleaning device, which can not only eliminate static electricity but also blow off dust, and can be used for cleaning the surface of objects such as belts. The ion air knife cleaning device includes an air knife body 1 and an ion bar 2. The air knife body 1 is used to blow out air flow, and the ion bar 2 is used to ionize the air around it to generate a large number of positive and negative ions. The generated ions are blown to the surface of the object to be cleaned along with the air flow blown out by the air knife body 1, achieving the purpose of instantly eliminating static electricity, blowing off dust and other particles. The air knife body 1 includes a wind cavity part 12 and an air outlet part 13 connected to the wind cavity part 12. Among them, the wind cavity part 12 is used to collect gas and transport it to the air outlet part 13, and the air outlet part 13 is used to blow out the air flow from the air outlet 131. The air outlet part 13 and the side wall of the wind cavity part 12 form a concave space, and the concave space can be in the shape of U, V, C, etc. The main purpose is to block and converge the ions generated by the ion bar 2 ionizing the air, and form a certain guidance for the flow direction of the ions. The ion bar 2 is parallel to the length direction of the concave space and is installed in the concave space. Thus, the ions generated by the ion bar 2 ionizing the air are preferentially generated in the concave space or at the opening of the concave space. The air outlet 131 is arranged at the end of the air outlet part 13 away from the wind cavity part 12, and the air flow at the air outlet 131 is within the opening angle range of the concave space. That is to say, when the air outlet 131 blows out air flow, the air flow will pass through the range facing the opening of the concave space. At this time, the air flow will carry the ions in the concave space and its opening, and blow the ions and the air flow to the surface of the object to be cleaned. At the same time, the air around the concave space is replenished to the concave space and its opening, and the replenished air is continuously ionized by the ion bar 2 to generate ions, so as to effectively utilize the generated ions.

[0033] The utility model uses the wind cavity part 12 and the air outlet part 13 to connect and form a concave space for accommodating the ion bar 2. The ions generated by the ion bar 2 can be gathered in the concave space. On the basis that the air flow at the air outlet 131 is within the opening angle range of the concave space, the air flow at the air outlet 131 can be used to carry the ions converged in the concave space to the surface to be cleaned. The concave space can prevent the ions from drifting, so that more ions can be utilized on the surface to be cleaned, thereby improving the ion utilization efficiency and enhancing the static electricity elimination effect.

[0034] Furthermore, the concave space can be an open V shape. The open V shape includes a first arm and a second arm with an included angle greater than 90 degrees. The first arm of the open V shape is connected to the end face where the air outlet 131 is located, and the second arm of the open V shape is parallel to the end face where the air outlet 131 is located. Thus, the setting position of the air outlet 131 is closer to the open V shape, and when the air outlet 131 blows out air flow, it can better carry the ions of the open V shape.

[0035] It may also include a bracket 3 connected to the second arm. The bracket 3 is provided with a mounting groove for mounting the ion bar 2. To better fix the position of the ion bar 2, at least two brackets 3 can be provided in the length direction of the ion bar 2, and the two brackets 3 are spaced at a certain distance.

[0036] The air outlet 131 can be a round opening, a square opening or an opening of other shapes. In a preferred embodiment, the air outlet 131 is arranged as a flat opening along the length direction of the air outlet part 13. The flat opening can blow out an air curtain-like airflow, which can cover a wider width. Thus, the width range of the air blown by the air outlet 131 is expanded, which is suitable for continuous cleaning of the surface of objects such as belts. The length of the flat opening is less than or equal to the length of the ion bar 2, so that the airflow blown out by the flat opening all carries ions, ensuring the amount of ions contained in the airflow and thus ensuring the static elimination effect.

[0037] It may also include a cover plate 7 connected to the top of the air outlet part 13. The top of the cover plate 7 is provided with mounting threaded holes 71, and the cover plate 7 can be mounted on the air outlet part 13 through the mounting threaded holes 71. In addition, the mounting threaded holes 71 can also be used as mounting holes for fixing other accessory devices.

[0038] The cover plate 7 may also be provided with a convex edge 72. The convex edge 72 is located on the side of the flat opening away from the first arm. Since the convex edge 72 protrudes from the flat opening, the convex edge 72 can be used to guide the airflow blown out by the flat opening, so that the airflow carries more ions in the concave space.

[0039] Mounting openings 11 are respectively arranged at both ends in the length direction of the air cavity part 12. The mounting openings 11 can fix the air cavity part 12 on a support frame or a mounting frame, thereby realizing the installation and fixation of the ion air knife cleaning device.

[0040] In a further solution, the ion air knife cleaning device further includes an air volume control device 5 connected to the air cavity part 12. The air outlet of the air volume control device 5 is connected to the air cavity part 12, and the air inlet 51 of the air volume control device 5 is opposite to the orientation of the air outlet 131, so that the air intake and air outlet do not interfere with each other. The gas entering through the air inlet 51 enters the air cavity part 12 through the air volume control device 5 and then is blown out through the air outlet 131 of the air outlet part 13. The air volume control device 5 is a currently known device and can control the air volume. For example, the air volume control device 5 can be composed of components such as an internal flow sensor, a laminar flow stratification member, a regulating valve and an amplification control circuit. The flow signal measured by the internal flow sensor is amplified, then compared with a set voltage, and the obtained difference is used to drive and control the regulating valve to close-loop control the flow through the channel to make it equal to the set flow.

[0041] It may also include a dust detection device 4. The dust detection device 4 can display the dust concentration in real time and record data. The dust detection device 4 can be battery-driven, including the ability to monitor the battery status and display the accurate operation time. The dust detection device 4 uses currently known devices. The dust detection device 4 is applicable to air sampling in aspects such as industrial hygiene and occupational safety, can collect dust or gas in the air, can measure the mass concentration and particle size, and can record data. The dust detection device 4 can be connected to the gas volume control device 5 or the cover plate 7. The gas volume control device 5 can be used in conjunction with the dust detection device 4 in a chain. When the dust detection device 4 detects a low dust concentration, the gas intake volume is reduced through the gas volume control device 5, and conversely, the gas intake volume is increased. The dust detection port 41 of the dust detection device 4 has the same orientation as the air outlet 131. When the air outlet 131 blows out air, the dust will be blown up, so that the dust detection device 4 can effectively detect the dust amount.

[0042] By setting the dust detection device 4 connected to the gas volume control device 5 in the present utility model, the dust concentration can be detected by using the dust detection device 4, and then the air output volume of the gas volume control device 5 can be adjusted according to the dust concentration, so that the ion air knife cleaning device can adapt to the change of the dust concentration, and avoid the problems of being unable to clean cleanly when the dust concentration is high and wasting the air volume when the dust concentration is low.

[0043] It may also include a speed detection device 6. The speed detection device 6 uses currently known devices. The speed detection device 6 is arranged at the rear side of the air knife body 1. The speed detection device 6 has high reliability, high sensitivity and good temperature stability. The speed detection device 6 can be used to detect the running speed of an object (such as a belt) moving relative to the ion air knife device. In a specific solution, the air outlet 131 can be used to face the belt to eliminate static electricity on the belt and at the same time clean the dust on the belt. When the speed detection device 6 detects that the belt speed is 0, the regulating valve of the gas volume control device 5 is closed. When the speed detection device 6 detects that the belt speed exceeds a certain speed, the regulating valve of the gas volume control device 5 is in an open state.

[0044] By setting the speed detection device 6 connected to the gas volume control device 5 in the present utility model, the running speed of the belt can be judged by using the speed detection device 6. When the belt is running, the operation of the ion air knife cleaning device is maintained. When the belt stops running, the ion air knife cleaning device is stopped, so as to effectively control the operation state of the ion air knife cleaning device and avoid the waste of ions and air volume caused by the idle running of the ion air knife cleaning device.

[0045] In this utility model, specific examples are used to expound the principle and implementation mode of the utility model. The description of the above embodiments is only used to help understand the method and its core idea of the utility model; at the same time, for those of ordinary skill in the art, according to the idea of the utility model, there will be changes in the specific implementation mode and application scope. To sum up, the content of this specification should not be construed as a limitation of the utility model.
