摘要： There is described a method and an apparatus for cleaning a dust separator which has a raw gas shaft (3), through which raw gas flows from the top to the bottom, and filter elements (5) protruding into the raw gas shaft (3) transverse to the raw gas flow, by which filter elements the raw gas is deflected into a clean gas shaft (4) under a corresponding separation of dust, and which filter elements are briefly subjected to compressed air one after the other for blowing off the dust particles deposited on the same into the raw gas shaft (3), where during the application of compressed air onto the filter elements (5) their flow connection to the clean gas shaft (4) is interrupted. To ensure a good cleaning effect, it is proposed that during the interruption of the flow connection between the filter elements (5) and the clean gas shaft (4) a raw gas stream having a flow component directed from the top to the bottom flows around the filter elements (5) blocked against the clean gas shaft (4).
摘要翻译：描述了一种用于清洁具有原料气体轴（3）的灰尘分离器的方法和装置，原料气体从顶部流到底部，以及过滤元件（5）突出到原料气体轴（3）中，横向于原始气体流动，通过该过滤元件，原料气体在相应的灰尘分离下被偏转到清洁气体轴（4）中，并且过滤元件一个接一个地短暂地经受压缩空气以吹除灰尘将颗粒沉积在原料气体轴（3）中，其中在将压缩空气施加到过滤器元件（5）上时，它们与清洁气体轴（4）的流动连接被中断。为了确保良好的清洁效果，建议在过滤元件（5）和清洁气体轴（4）之间的流动连接中断期间，具有从顶部到底部的流动分量的原料气流围绕过滤元件（5）阻挡清洁气体轴（4）。

摘要： A rotary screen assembly rotatable about a rotational axis for filtering air entering an air inlet of a work machine, the screen assembly having an axially facing screen surface including an outer circumferential edge disposed around the rotational axis in radially spaced relation thereto, an elongate brush having bristles disposed along a longitudinal extent thereof in contact with the axially facing screen surface for brushing collected material and contaminants therefrom, the longitudinal extent or axis of the brush forming a chord of the outer circumferential edge spaced a distance from the rotational axis or being skewed relative to the rotational axis such that when the screen is rotated about the rotational axis in a predetermined direction a force is imparted to the collected material and contaminants by the bristles of the brush sufficient to move the collected material and contaminants radially outwardly past the circumferential edge. The screen surfaces are preferable substantially continuous and smooth and the axially facing screen surface is preferably flat and can include a plurality of screen panels removably disposed around a center hub through which the rotational axis extends, each of the screen panels including a peripheral frame defining an opening therethrough, and a screen fabric permanently attached to and preferably flush with the frame around the opening in covering relation thereto, allowing quickly and easily replacing the panels as they wear or are damaged.

摘要： A dust collector for handling high temperature process gases such as air containing dust and dirt. The collector includes a cylindrical filter housing and a clean air plenum mounted over the housing. A series of ceramic filter tubes are mounted in a tube sheet situated between the housing and the plenum and hot dirt containing process air is drawn from the housing into the plenum through the filter tubes. A blowdown system is mounted in the plenum over the filter tube for periodically pulsing a jet of dirt removing air into the filter tubes with sufficient force to remove dirt and dust collected upon the filter tubes. The valves and the inlet piping to the blowdown tubes are protected from the heat generated in the housing by a pair of spaced apart heat shields that are designed to conduct a natural flow of cool ambient air over the pipes. Heat exchanger fins are mounted upon the pipes to further enhance the cooling process.

摘要： A door assembly for securing an elongate filter cartridge in a dust collector. The door assembly utilizes a mounting plate engaged with the cover of an elongated filter cartridge so as to substantially seal the cartridge opening. The filter cartridge and mounting plate surround a support rod which extends through an aperture in an outer door that is engaged with the door wall of the dust collector so as to substantially seal the entrance of the dust collector. A spring assembly is positioned about the rod connects the door to the mounting plate. A compression spring within the spring assembly extends between the door and mounting plate, and a holder is tightenably and removably engaged with the end of the support rod thereby applying a closing force along the rod and sealing the cartridge in position in the dirty-air chamber.

摘要： The invention relates to a filter dedusting arrangement in a vacuum cleaner, wherein dedusting of the filter or filter-parts is effected by supplying a secondary airflow, in a known manner. The distinctive feature of the invention is that the secondary airflow through the filter for dedusting is controlled so that by utilizing differences in pressure a flap element arranged in a casing abruptly changes its position and opens and/or closes one or more openings in the casing so that the secondary airflow impinges impulsively on the surface of the filter to be dedusted. The impulsive supply of secondary air to the filter produces a much better cleaning action.

摘要： The present invention is concerned with the cleaning of fouled air filters to alleviate the problems caused by disposal of such filters as waste and to reduce the cost of maintenance of the many apparatus requiring air filters. The present invention provides a motorized turntable provided in a filter chamber in a housing whereby the fitter can be spun on its axis at a speed sufficient to discharge the fouling into the filter chamber. The fouled atmosphere in the filter chamber is exhausted to a vacuum chamber where the fouling settles out for disposal.

摘要： An adjustable duct assembly for the collection of fumes, dust and the like comprises two duct sections connected end to end by a duct support system comprising two elongate arms pivotally connected, the arms attached to the adjacent ends of the ducts, externally. A counterbalance arm extends from the duct support of a lower or outer duct section beyond the pivot point of the elongate arms, to counterbalance the lower or outer arms. A filter arrangement may be associated with the duct assembly, consisting of a generally planar filter element within a housing. A travelling nozzle arrangement directs a stream of air in a direction countervailing the normal flow through the filter, for backwash cleaning of the filter. First and second drives propel the nozzle simultaneously across and along the filter, to provide full backwash cleaning coverage of the filter.

摘要： An exhaust system for a diesel engine which includes a particulate filter for filtering a flow of engine exhaust gas includes, as part of the exhaust system, a catch basin for the collection of oxidation by-products from the particulate filter. Important in the design is to orient the particulate filter in a generally vertical orientation based upon the normal orientation of the diesel engine when in use. By vibration of the engine due in part to engine operation and due in part to vehicle vibrations, oxidation by-products shake loose from the particulate filter and fall through a connecting conduit. By positioning the catch basin below the particulate filter and connecting it to the conduit, the oxidation by-products are able to be collected in the catch basin for removal at a later time.
