Definitions

  • the present invention relates to what is claimed in the preamble and is concerned with improvements to bed load retention shafts.
  • Sluice retention shafts are known. Reference is made to this in particular to DE 199 33 391 A1. Geschieb Kohlhaltemchte are provided in sewers to prevent that mineral debris carried along with the waste water and the like in the process engineering area a sewage treatment plant or the like arrives where it is troublesome and / or can be destructive, as well as prevented should be that the bed load itself in sewer pipes deposits and inhibits the flow there. With these debris shafts it is placed between pieces of sewer pipe Manholes, with the wastewater above the shaft floor flows in and out. This leads to the heavier mineral Attachments can sink and settle on the shaft bottom collects. In order for the arrangement to operate properly, it is necessary the bedlock shaft depending on the bedload to clear repeatedly in the waste water. This clearing happens typically by dredging or the like and requires also a lot of work.
  • a device for catching and washing out the sand Waste water is also known from DE-PS 539 448.
  • This shows a device for catching and washing out the Sand from waste water, consisting of a settling tank with Skimmer, which is the mixture of sand and organic Contaminants connected to the settling tank Feed space in which the separation of the sand from the organic Mud is done by washing out, being deepened in the Collected pit washout a compressed air line for washing out the sand and a conveyor intended to convey the washed-out sand are.
  • the washed-out sand should be by means of a bucket elevator or the like are promoted.
  • the promoted upwards Deposits get into a ready via a slide standing dump truck or the like.
  • the arrangement shown provides for a central bucket elevator, which is located centrally in the The inflow area of the waste water lies at the bottom of the collecting pit is swept by it in a tangential movement.
  • the object of the present invention is to create something new to provide for commercial use.
  • the present invention thus proposes a first The basic idea of a bed load compartment arrangement with at least a moveable shovel for the piling and a means for blade movement, in which provided is that the means to move the bucket along the bottom of the bedlock guided scooping chain includes.
  • a first essential aspect is therefore in the knowledge too see that a significant improvement even when clearing can be obtained by doing this individual shovels can be moved over the bottom of the bedlock and so attachments up to the inclusion in the shovel can float here. This improves the clearing result compared to gripping blades essential, where in addition to the Material often remains in the closing area. In addition, through not just moving a bucket tangentially but that Dragging a shovel over a longer area of the bedlock bottom more even wear of the same achieved with improved clearing effect.
  • the clearing time is provided by a A plurality of movable blades is reduced. You can the blades that are spaced on the blade dragging chain are attached from each other, so far from each other be spaced so that only one at the bottom of the shaft drives along. This reduces the load on a drive significant, so that this is designed weaker and therefore can be made cheaper. However, it is already preferred if the blades are spaced so far that the Time in which a variety of blades in contact with the ground are compared to the time when this is not the case is short
  • the blade will typically be formed as a perforated blade, what it allows the waste water in the bucket to drain when the bucket is raised above the waste water level in the bedlock permit.
  • the holes can be done without interference of the function so large that Sand and the like is partially drained. The reason this is because of such fine substances that go back to the Attachment shaft arrive, there is no danger that the attachment shaft gradually becomes clogged, at least because of Larger amounts of silt etc. are essential parts in the Shovel will remain and / or such fines coarser debris can be lifted and removed together can.
  • the present Invention thus also removes sand, but primarily on a removal of coarser bed load, mineral substances etc. is aligned.
  • the shoveling is Chain on a construction that is fixed to the sliding shaft appropriate.
  • This can be multiple individual ones a deflection pulley attached to the attachment shaft wall or, if several drag chains are provided around axes act with several such roles that are firmly attached to the bedlock are appropriate; however, it is preferred if a Complete frame is provided, which is typical in a standardized bed shaft extends from the walls to the floor, whereby it is possible the entire arrangement largely pre-assembled and quickly on site in one To install debris shaft. This in turn enables the Prefabrication arrangement in a manufacturing plant what the Total manufacturing costs reduced.
  • the frame can be typical be designed so that it extends over the edge of the bedlock shaft across so far that the blades can be emptied into a container, such as a container or the like, with which immediately without further handling a removal of the excavated bedload becomes possible.
  • the arrangement of the drag chains close on the attachment shaft wall be it directly on this or by one arranged close to the attachment shaft wall Frame arrangement also allows a trouble-free To allow flow through the debris shaft. The main reason for this is that the downward movement of the Shoveling takes place on a first wall, so away from the typical one central inlet and outlet, then the blades to be carried along under the current and the bottom of Remove deposits and then the shovels on the attachment shaft walls, typically the one opposite the entrance wall, again without disturbing the flow be moved up.
  • the preferred Assembly walls are between the inflow and outflow walls arranged.
  • the chain attachment on a Longitudinal shaft side to be provided. Because now the blades close to the shaft and therefore close to the edge, the means to be listed and removed near the solid ground a slide for excavated debris or other debris also unnecessary. This lowers the overall cost and makes maintenance easier.
  • the blades are typically mounted on two generally parallel ones Chains attached, which ensures that no tipping in the case of one-sided or unevenly acting loads, for example by being distributed unevenly on the bedlock shaft floor Attachments impaired function.
  • the chains are typically routed near the bed-shaft base are, and preferably axis-free, that is such that those below the chains on the floor of the bed or near also not jammed by stones along running blades can be located between the bucket and an axis wedge.
  • the chain is typically formed as a link chain, because link chains are inexpensively available in sufficient stability. It is particularly preferred if each blade has two edges close to the edge Make the chains connected as this is for one ensures particularly stable movement. It is possible to have a drive to be provided, which is assigned to at least one chain, the drive of both or all chains is preferred. This drive can be operated intermittently or intermittently be so that the conveyor only briefly each must be operated. This is typically the case with the accumulating debris quantities completely sufficient. Prefers a profile is provided in the debris shaft ensures that debris transported from the inflow slides into the clearing area so that there are no dead zones.
  • Fig. 1 comprises a generally designated 1 attachment shaft clearing arrangement 1 with at least one movable Shovel 2 for clearing debris from the ground 3a Bedding shaft 3 is a means for moving the shovel 4 as a shoveling chain or tow rope arrangement 4 is formed.
  • the bed load compartment clearing arrangement 1 is dimensioned so that that they were transported to a debris shaft Attachment quantities can then be cleared out in an adequate time without any problems can be, for example, after heavy rains in the Spring large amounts of chippings and the like quickly in the Flow in the bedlock. This dimensioning determines the design of the chain and bucket load capacity as well as the Bucket volume and drive power.
  • the blades 2 are distributed along the chains 3 so that on Attachment shaft floor 3a along only one shovel at a time is moved. In other words, the distance between the blades 2 to each other along the chain at least as large as the width of the bedlock base 3a.
  • the blades are one Corrosion-resistant, dimensionally stable material, sufficient here thick stainless steel sheet, formed and in its lower area with a perforation, which allows a fast drainage of Water allows, but is only so large that essential Parts of the bed load are retained in the shovel.
  • the blades 2 themselves are in the edge areas Link chain 4 attached, so that the location relative to the link chain regardless of the orientation in the Space is constant, i.e. the shovel is not around the link chain swings.
  • the bedlock shaft 3 is a bedlock shaft of standardized Size in the well above the bedlock shaft bottom 3a water contaminated with mineral bed load through an opening 3c flows in and out, also clearly above the bedlock shaft bottom 3a, water without bedload from a Opening 3b flows out.
  • a profiling 3d provided by the Clearing zone just below or around the opening 3b rises obliquely and has such a slope, that the floating and floating organic matter with the water flow to the sewer leading to the sewage plant optimally fed. This prevents dead zones in which material collects for a long time without clearing could.
  • the dead zone prevention profiling 3d further comprises a bevel 3d1 on the edges, which corresponds to the movement of the Buckets is adjusted. An arrangement of a profile in the Inflow range would also be possible.
  • a coarse-bubble aeration of the mixed water required in the debris shaft is preferably done through a ventilation line, installed in the drop-off area of the bedlock shaft and is introduced into the compressed air.
  • the chain 4 is formed from two parallel link chains, the along the axial, that is between the inflow and inflow end faces provided shaft walls 3e, 3f and the shaft floor are guided over suitable rollers 5, the rollers 5 in turn are attached to a frame (not shown) which is in turn firmly arranged in the bed shaft 1.
  • the guide rollers 5 are held spaced from the floor, and such a piece that the blades 2 below the Link chain with only a short distance to the bedlock bottom 3a are performed. The same applies to the distance the link chain from the walls, due to the small spacing it is ensured that the flow through the The shovel is not affected by the shovel.
  • the link chains 4 are outside via further deflection rollers of the debris shaft to a drop zone 6, in which for emptying the blades into a container Container is provided and where there is a drive (not shown) for the intermittent further movement of the link chain is provided.
  • the link chain is made of high quality Steel formed and dimensioned so that even large amounts of debris can be transported away in the blades.
