Abstract

The present invention provides a rotary dust collector having a water-blocking section. The rotary dust collector having a water-blocking section comprises a main body section that is positioned in a waterway and includes a rake section that is transported by the drive of a drive chain to scrape and remove debris flowing along the waterway to the outside, and a water-blocking section that is connected to the main body section and positioned in the waterway at a set distance from the front end of the main body section and opens and closes the waterway as external power is provided.

Description

A rotary dust removal machine having a water stop The present invention relates to a rotary dust collector having a water-blocking section, and more specifically, to a rotary dust collector having a water-blocking section that is integrally formed at one end of the main body of the rotary dust collector placed in a waterway, and when maintenance is performed on the main body, the water remaining at the lower end of the main body is drained to the outside after the waterway is blocked, thereby facilitating maintenance of the main body. In water treatment facilities such as sewage treatment plants or wastewater treatment plants, it is necessary to effectively remove various types of debris (e.g., vinyl, branches, fabric scraps, plastics, etc.) contained in sewage or wastewater flowing in through waterways at an earlier stage of the treatment process. If these contaminants are not removed in the initial stage, they can cause contamination or malfunction in the equipment of subsequent processes, so dust removers are generally used as pretreatment devices. Conventional dust collectors are classified into various types, such as manual, rotary, belt, screw, and chain rack types, depending on their structure and operating method. Among these, chain rack dust collectors are widely adopted in small and medium-sized water treatment facilities due to their relatively simple structure and excellent solid removal performance. However, chain rack type vibration dampers have the following problem: since the lower part of the device is installed submerged in the waterway, it is difficult for workers to access the bottom of the device during maintenance and repair work. In particular, in order to repair the device, the repair process must involve visually inspecting the faulty part at the bottom of the main unit of the vibration damper, and since water barrier or drainage measures must be performed separately, the work is complex, inefficient, and time-consuming. In addition, it is difficult to respond immediately if debris accumulates at the bottom of the dust collector or if mechanical malfunctions occur, which can hinder the normal operation of the equipment. As a result, maintenance efficiency decreases, which may lead to increased operating costs and a decrease in facility utilization rates. Conventionally, to address these issues, Korean Registered Patent No. 10-1828035 proposed a rotary type vibration damping device integrated with a sluice gate for maintenance, equipped with a sluice gate that opens and closes a waterway. However, this device lacks an interlocking function that automatically operates the sluice gate based on maintenance signals from a separate sensor or system that detects malfunctions or conditions requiring maintenance of the damper. Consequently, there is the inconvenience of requiring a worker to manually operate the sluice gate on-site, and its application is limited in emergency situations or unmanned facilities requiring automation. Furthermore, since conventional technology integrates the sluice gate into a fixed structure on the inlet channel of the debris collector, it is difficult to freely adjust the gate's position or perform customized construction according to the installation environment or channel structure of the water treatment plant. This acts as a limiting factor for installation and application, particularly in small and medium-sized treatment facilities with space constraints or during the renovation of aging channels. In addition, conventional technology requires the entire dust collector to be lifted during maintenance, and since the lower part of the device is submerged in water, there is no separate structure or means provided to effectively drain water accumulated inside or at the bottom of the dust collector even when the sluice gate is closed. Consequently, not only is it difficult for workers to access the area during maintenance, but the safety and efficiency of the working environment are also reduced. In particular, if debris accumulates at the bottom and causes a malfunction or blockage, there is a problem in that it is difficult to even access the affected area unless the water is drained. In addition, in conventional technology, even when the sluice gate is closed, a small gap may occur between the lower part of the sluice gate and the bottom of the waterway, and foreign substances deposited on the bottom of the waterway may enter through this gap. These foreign substances pass through the rear of the dust collector and are not filtered out by the screen or rake, or interfere with the operation of the dust collector, and increase the likelihood of contamination or malfunction during maintenance.
