Description

Gravel collector

Technical Field

The utility model belongs to the field of rain and flood control equipment, and particularly relates to a gravel collector.

Background

In the pipeline for conveying combined sewage or rainwater, some coarse impurities, such as gravel and various fragments, exist, the movement speed of the coarse impurities is slower than that of water flow, so that downstream devices and equipment are easy to break down, a water inlet and pump station equipment are damaged, and the normal operation of the equipment is influenced. The latter can be avoided by installing a sand setting station and a grid machine, and by draining and emptying periodically, the system can be kept running smoothly. The former requires determining the source of grit and debris entering the sewer system and removing it.

In conventional sand removal systems, a concrete chamber is often installed at the sewage canal section to collect the gravel. In this concrete chamber, ventilation ducts are installed to aerate the gravel and air supply keeps the organic particles in suspension, leaving them in the waste water stream. The sand particles can be removed with a stationary or mobile lifting device or a vacuum cleaner. The sand removal is usually carried out during operation, i.e. when the basin sewer is flooded, in which case there is a risk of damage to the equipment or damage to the civil structure of the lifting system. If a suction vehicle is used for disassembly, the access to the structure must be closed. Furthermore, in pipelines and channels, it is often not feasible to provide conventional concrete chambers. Gravel is easy to harden after being accumulated for a long time and is more difficult to handle. Therefore, the traditional mode of building a concrete chamber to remove sand has the problems of insufficient applicability, incapability of removing sand during the operation of a sewage pipeline, low efficiency, easy hardening of gravel, difficult treatment and the like.

(II) technical scheme

In order to achieve the purpose, the utility model provides the following technical scheme:

the gravel collector comprises a cross beam, guide rods, chains, hanging trays, sand catching baskets, sealing rings, unlocking levers, grids, a foundation pit and sand guide plates, wherein the cross beam is transversely arranged, a cubic foundation pit is arranged under the middle part of the cross beam, four cubic sand catching baskets with the same height are placed in the foundation pit, the sand catching baskets are arranged in two rows and two columns, the sealing rings are arranged between the periphery of the sand catching baskets and the wall of the foundation pit, the bottom surfaces of the sand catching baskets are two rectangular grids, one long side edge of each grid is hinged with one bottom edge of the foundation pit, the other long side edge of each grid is connected with the vertically unlocking lever, the sand guide plates transversely penetrate between the two rows of the sand catching baskets of the foundation pit, the side surfaces of the sand catching baskets are connected with the bottom ends of the vertically arranged guide rods, the top ends of the guide rods positioned at the four sides of the foundation pit are connected with the cross beam, the hanging trays are respectively arranged right above the sand catching baskets, and are connected with the four top angles of the corresponding sand catching baskets through the chains, the connecting part of the guide rod and the cross beam is also connected with the hanging scaffold through a chain.

Preferably, the sand catching device further comprises four air hoses, the bottoms of the air hoses are communicated with the sand catching basket, and the tops of the air hoses are fixed on the cross beam.

(III) advantageous effects

Compared with the prior art, the utility model has the following beneficial effects:

install the grit collector in two sections water piping connection departments, when the sewage that contains the grit flows through, because the foundation ditch is bulky, the sewage speed of flowing through can reduce, the grit falls into sand catching basket along with the action of gravity, and the sealing washer is used for the sealed clearance between sand catching basket and the foundation ditch wall. The sand guide plate reduces the retention time of sewage in the foundation pit area, and reduces the deposition of light materials to the maximum extent. When the gravel is collected to a certain amount, the sand catching basket is completely lifted out of the foundation pit through a series of force transmission of the guide rod, the chain and the hanging scaffold, the sand catching basket is moved to a gravel and debris treatment place, the grating at the bottom is opened, the unlocking rod in the middle is pulled to fold the sand catching basket, and the gravel is poured out. After the sand catching basket is emptied, the grating is rotated backwards, then the sand catching basket is placed back to the foundation pit, and the gravel collector can be used again.

Preferably, the air hose drives compressed air into the gravel in the sand catching basket, so that the gravel can be washed away to prevent hardening; on the other hand, the friction between the gravels and the washing of water can wash out the pollutants such as oil stains on the surface of the gravel; on the other hand, good ventilation and recirculation can also be ensured.
