The invention concerns a system for intercepting and collecting bodies in a flow of a fluid, comprising: a pipe portion (18) comprising an inner face that defines an axial inner passage for the flow, a filtering surface (25) including an upstream face (25a) and extending transversely in the passage so as to intercept, by its upstream face, bodies conveyed by the flow whilst leaving exposed a plurality of collection openings (26a, 26b) between the filtering surface and the inner face, a cleaning device (30) that is arranged across from the upstream face (25a), the device (30) and the filtering surface (25) being in motion with respect to one another such that each zone of the upstream face is mechanically swept by the device during each alternating relative back and forth movement in order to orient the bodies intercepted by the upstream face (25a) toward the collection openings for said bodies.

A device for separating and removing sieve material from a flowing liquid includes a sieve grate that forms a sieve surface and is fixed to a frame. The sieve grate has several grate bars arranged beside one another and with at least some sections separated from one another by spaces. At least one cleaning rake has numerous cleaning prongs, the cleaning rake being movable along the front side of the sieve grate using a drive in such a way that at least sections of the cleaning prongs engage in the above-mentioned spaces when passing the sieve grate to remove sieve material held back by the sieve grate and convey it toward a device discharge. The cleaning rake has cleaning prongs that engage with variable depth into the above-mentioned spaces of the sieve grate.

The invention relates to a filter device for polymer melts, having a filter screen (1), through which the polymer melt to be purified is guided, wherein the filter device comprises at least one scraping element (2), which glides across the upstream surface (4) of the filter screen (1) with its scraping edge (3), or rests on the surface (4) with its end area nearest the scraping edge (3), and lifts off and/or scrapes off the contaminations (6) adhering to the surface (4) and those present in front of the screen orifices (5) in the course of its movement across the surface (4). According to the invention it is provided that the scraping element (2) is embodied in the shape of a disk, in particular comprising parallel, preferably plane large surfaces, i.e. a back face (8) and a front face (9) and is disposed at an inclined pitch (A) of 5 to 60°, preferably 10 to 45°, in particular 20 to 35° toward the surface (4) of the filter screen (1).
摘要:
A vehicle for collecting and compacting waste for disposal including a compaction chamber, configured to receive and compact waste, having an opening for inserting waste to be compacted and a plurality of apertures in at least one internal surface of the compaction chamber. The compactor is configured to apply pressure to the waste in the compaction chamber to reduce the volume of the waste. When the compactor applies pressure to the waste, liquid and residual solid waste exits the compaction chamber through the plurality of apertures. There is a liquid collection system, configured to collect the liquid and the residual solid waste from the plurality of apertures and the liquid collection system includes an evaporation system configured to evaporate at least a portion of the liquid removed from the waste.

A filtration device including: a casing; a first partition wall which partitions the inside of the casing into a first raw fluid chamber and a filtered-fluid chamber; cylindrical filter elements provided inside the filtered-fluid chamber and of which the inside communicates with the first raw fluid chamber to let fluid pass through from inside toward outside to filter the fluid; a second partition wall provided on the other end of the filter elements to form a second raw fluid chamber; a wash pipe connected to an end of the filter element to let fluid flow from the raw fluid chamber in the axial direction to wash the filter elements; and a wash fluid drain pipe which discharges trapped substances, wherein the other end of the filter element connected to the wash pipe is always open to the raw fluid chamber.
摘要:
A screen assembly configured to separate coarse (larger) and fine (small) materials from an effluent flow. The assembly includes a plurality of bars having different heights. The bars are arranged to form larger spaces for separating coarser material from the effluent flow, and arranged to form smaller spaces for separating finer materials from the effluent flow. The effluent flows into the larger spaces first, and subsequently flows out of the smaller spaces. The assembly includes a cleaning device operable to remove the materials from both the large and small spaces.

This invention refers to a device for separating and removing sieved material from a flowing liquid such as sewage, in which case the device has a sieve grate (1) with a sieve surface with a front side (2) pointing upstream while the device is operating, in which case the device has a supplementary grate (3) in a lower area of the sieve grate (1) placed upstream before the sieve grate (1), in which case the device has a drive (24) and a cleaning rake (4) that can be driven to revolve in a conveying direction with the help of the drive (24), in which case the operating cleaning rake (4) is moveable along at least one partial section of the front side (2) of the sieve grate (1) in order to remove the held-back sieved material and transport it towards a discharge opening (5) and wherein the cleaning rake (4) can be moved along a back side (6) of the supplementary grate (3) pointing downstream while it is moving in order to remove sieved material held back by the supplementary grate (3) and transport it towards a discharge opening (5). According to the invention, it is suggested to move the supplementary grate (3) relative to the sieve grate (1).
摘要:
There is disclosed a trash rake system for use in clearing debris from an intake screen of an intake trash rack of a water intake port of a water use facility. The intake screen is configured to collect debris transported by water, for example, a river, to prevent the debris from entering the intake port of the water use facility. The trash rake system includes a track system, a movable support structure, a rack and pinion drive mechanism, and a controller configured to receive signals from an encoder on a drive motor and a proximity sensor system.
