Description

The portable washing unit of Barrate type grilling trash remover

Technical field

The utility model relates to the water treatment mechanical field of removing contamination, and relates in particular to grilling trash remover.

Background technology

Barrate type grilling trash remover is widely used in the intake of facilities such as sewage work, tap water intake, large, lake, river comprehensive administration project, rainwater water drainage and sewage pump station, this equipment is with water source intake floating matter and settling Salvage and Wreck Removal, and dirt extracted dehydration, discharge the compression back.

As shown in Figure 1, Barrate type grilling trash remover is mainly by the Barrate type grilling assembly 1 in about 1/3 zone of front end, and the conveying compression section assembly 2 and the outside cleaning assembly 15 that are arranged in about 2/3 zone, rear end are formed.As the equipment axis, this screw conveyor shaft 7 drives by the motor 10 that is installed in the end Barrate type grilling trash remover with the screw conveyor shaft 7 that runs through entire equipment length; The Barrate type grilling assembly 1 of front end is provided with grid rotary drum 4 and at the transfer container 5 of rotary drum inside, grid rotary drum 4 is connected on the screw conveyor shaft 7 with bearing 3 in the end, the rotation that the two-wheel support assembly 16 by as shown in Figure 2 and the single-wheel support assembly of both sides 18 are realized around screw conveyor shaft 7.The conveying compression section assembly 2 of middle rear end mainly comprises screw conveyor shaft 7, transport pipe 8, is positioned at terminal blowdown outlet 11 and water shoot 13.Whole drum formula grilling trash remover is installed in the intake forward water channel by fore-stock subassembly 14 and back adjustable support 12.

As shown in Figures 2 and 3, in grid rotary drum 4 arranged outside fixed outside cleaning assembly 15 and fixing hairbrush 17 are arranged, these two subassemblies all run through the axial length of rotary drum, wherein outside cleaning assembly 15 as shown in Figure 4, both sides have

support

21,22, and the water pipe 24 that runs through the whole drum axial length is installed on the

support

21,22, have a plurality of all apart from the nozzle 23 that distributes on the water pipe 24, be connected with magnetic valve 9 by the water pipe among Fig. 16, control the input of wash-down water by magnetic valve 9.Hairbrush 17 is fixed on the frame, the grid outer side of its bristle contact rotary drum.

When reality was used, as shown in Figure 1, Barrate type grilling trash remover made it become 35 degree to be installed in the water channel with horizontal plane by installing and regulate fore-stock subassembly 14 and back adjustable support 12.Sewage is from rouse according to WI direction signal inflow as shown in Figure 1 the end of rotary drum, and by the outflow of the lateral grid seam of rotary drum, flow out sewage as WO direction signal among Fig. 1, dirts such as the suspended substance in the water, floating matter are owing to can not stay rotary drum inside by grid simultaneously; Grid rotary drum 4 is under the driving of motor 10, with certain speed rotation, the dirt of rotary drum inside is rotated the top that drives the grid rotary drum, under the effect of self gravitation, dirt drops among the transfer container 5 of rotary drum inside, the screw conveyor shaft 7 that is positioned at the bucket bottom of transfer container 5 is involved in dirt, and the conveying compression section of rear end in being delivered to by spiral motion, and dirt is extracted dehydration and compression in transport pipe 8; The water that is squeezed out is discharged by water shoot 13, when dirt is transported to end, discharges from blowdown outlet 11, transports through transfer roller.

Cleaning to grid is to guarantee the normal effectively important process of operation of equipment, and the obstruction of grid not only can cause the minimizing of water flowing flow, and rotary drum weight is increased, and motor load is big during operation, the big even structure deteriorate of energy consumption., size various owing to dirt types such as suspended substance, floating matter in the sewage differs greatly, and for the dirt of large-size, adopts this Barrate type grilling trash remover better to realize removing contamination; But near the dirt in grid aperture plate gap, then embed the grid aperture plate for size extremely easily, cause the obstruction of aperture plate, be difficult to the work of finishing drainage and removing contamination.Therefore, as Fig. 1, Fig. 2 and shown in Figure 4, existing Barrate type grilling trash remover is provided with a cover fixed outside cleaning assembly 15 and fixing hairbrush 17, in the time of drum rotating, magnetic valve 9 control wash-down waters are delivered to outside cleaning assembly 15 by water pipe 6, form water jets under high pressure by nozzle 23 and carry out jet douche, and hairbrush 17 can brush the dirt between the grid gap, thereby reach the cleaning purpose from the outer side of rotary drum.

But in actual use, a plurality of nozzles 23 are being sprayed water all the time, can consume a large amount of wash-down waters, and especially under the less water environment of some dirts, the cleaning amount is less, there is no need opening all the time the outside fixedly cleaning assembly 15 clean.

The utility model content

At the outside of Barrate type grilling trash remover in the prior art fixedly washing nozzle must carry out work simultaneously by a plurality of nozzles, problems such as waste wash-down water resource, and the portable washing unit of a kind of rational in infrastructure, the Barrate type grilling trash remover that provides with higher cleaning efficiency.

The technical scheme that the utility model adopted is as follows:

A kind of portable washing unit of Barrate type grilling trash remover, comprise that two ends are connected in the support in the outside, grid rotary drum both ends, parallel device leading screw and limit shaft on the support, one end of leading screw is connected with speed reduction unit and motor, by the screw connection sliding shoe, sliding shoe and limit shaft are slidingly connected on the leading screw, and washing nozzle is installed on the sliding shoe, washing nozzle is connected with the water source by water pipe and magnetic valve, and the both sides of described sliding shoe are provided with limit switch.

The utility model is installed on the Barrate type grilling moral outside, can be at the less water environment of dirt, and under the less situation of cleaning amount, open the utility model single nozzle that moves in circles separately and clean, can save great amount of water resources, reduce energy consumption.
