Description

Technical Field

[0001] This utility model relates to the field of hanging dry filtration technology, and in particular to a top-mounted dry filtration structure. Background Technology

[0002] A top-mounted dry filter is a specific structural form used in fields such as air filtration. Dust-laden air enters the top of the device and, as it passes through the filter material, dust and particles are blocked, while clean air permeates through and enters the space or equipment below, thus achieving air purification. As the filtration process continues, dust gradually accumulates on the surface of the filter material. When it reaches a certain level, it affects the filtration effect and airflow, requiring cleaning or replacement of the filter material.

[0003] In existing technologies, the installation process of some devices is complex and difficult, requiring more manpower and time. Specialized technicians are needed to spend extra effort on installation and debugging, increasing labor costs. This also increases the likelihood of errors during installation, and the collapse of the dry paper box can damage the integrity of the filter structure, preventing the filter material from functioning properly. Consequently, some dust and particulate matter may pass through the filtration system without being effectively filtered and enter the space or equipment requiring purification, affecting the air purification effect. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a top-mounted dry filtration structure. This structure allows for the rational planning of production layouts by utilizing the freed-up ground space, such as adding production equipment or optimizing material storage areas. This further improves space utilization efficiency, indirectly reduces the production cost per unit product, and enhances the economic benefits of enterprises. The dry cardboard box will not collapse and maintains good structural stability during long-term exposure to aerosol filtration and airflow impact.

[0005] To achieve the above objectives, a top-mounted dry filtration structure is provided, comprising a workpiece, a grille and its support at the bottom of the workpiece, two mixing zones inside the grille and its support, a trolley hanger at the bottom of the mixing zones, an upper trolley at the bottom of the trolley hanger, and a dry paper box inside the upper trolley.

[0006] According to the aforementioned top-mounted dry filter structure, a pressing device is provided on the outside of the dry paper box, and a sealing strip is provided on the outside of the dry paper box.

[0007] According to the aforementioned top-mounted dry filtration structure, a dry trolley entrance / exit is provided on the outside of the trolley hanger, and a dry trolley enclosed area is provided at the bottom of the dry trolley entrance / exit.

[0008] According to the aforementioned top-mounted dry filtration structure, a dry trolley exhaust pipe is provided at the bottom of the closed area of ​​the dry trolley, and multiple trolley pulley groups are provided at the top of the trolley frame.

[0009] According to the aforementioned top-mounted dry filter structure, a trolley locking device is provided at the bottom of the trolley hanger, and a dry paper box frame is provided outside the trolley locking device.

[0010] According to the aforementioned top-mounted dry filter structure, the exterior of the dry paper box frame is provided with a dry trolley push-pull handle.

[0011] Beneficial effects:

[0012] 1. The top-mounted dry filter structure is easy to install and saves space. Within the limited space of the spray booth, by installing the filter structure high up, a significant amount of floor space is freed up. Enterprises do not need to expand their factory area to accommodate the filtration equipment, saving on land rental or factory construction costs. Furthermore, the freed-up floor space can be used for rational planning of the production layout, such as adding production equipment or optimizing material storage areas, further improving space utilization efficiency and indirectly reducing the unit production cost of products, thereby enhancing the enterprise's economic benefits.

[0013] 2. Because dry-type cardboard boxes do not collapse, they maintain excellent structural stability even under long-term exposure to paint mist filtration and airflow impact. This means that frequent box replacements due to collapse are unnecessary, reducing maintenance material costs. Simultaneously, the stable box structure reduces the risk of damage to subsequent waste gas treatment equipment caused by poor filtration, decreasing the frequency and cost of related equipment repairs. Overall, this significantly reduces equipment maintenance costs, extends equipment lifespan, and improves the return on investment.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
