Description
Technical Field
The utility model relates to a backwash anti-blocking slag bin water filter which can be widely applied to a boiler wet slag treatment process.
Background
The existing slag bin has the defects of large moisture content, large volume capacity of cooling water in the slag bin, large volume of the slag bin and high cost. Moreover, if the wet slag water removal treatment is not performed, the slag cannot be comprehensively utilized.
Disclosure of Invention
The utility model aims to provide the backwash anti-clogging slag bin water filter which has good backwash effect, prevents the filter plate net from being blocked, is convenient to take out, replace or clean the filter plate net, has easy disassembly and maintenance of a backwash spray pipe assembly, has good sealing performance, and can comprehensively utilize dewatered slag as building materials.
In order to achieve the above purpose, the backwash anti-blocking type slag bin water filter comprises two side plates arranged on the outer side surface of a slag bin shell, two concave sliding rails arranged on the inner side surface of the side plates, a filter screen frame provided with a filter screen net and arranged in the concave sliding rails, a front plate arranged on the plate frame, a plurality of backwash spray pipe cover plates arranged on the front end surfaces of the two side plates through backwash spray pipe cover plate bolts, backwash pipelines arranged on the backwash spray pipe cover plates, backwash valves arranged on the backwash pipelines, a plurality of backwash spray pipes arranged on the tail ends of the backwash pipelines, a plurality of backwash spray heads arranged on the backwash spray pipes, a flange seat arranged on the side plates, a sealing piece arranged on the top surface of the flange seat, an upper cover plate arranged on the flange seat together with the sealing piece through upper cover plate bolts, a lower cover plate arranged on the lower end surfaces of the two side plates and a drain pipe arranged on the front plate.
The utility model relates to a backwash anti-blocking slag bin water filter, wherein an upper cover plate, two side plates, a lower cover plate, a front plate and a slag bin form a sealing space.
The utility model relates to a backwash anti-blocking slag bin water filter, which has the following working principle:
(1) The water-containing material enters the slag bin and is isolated at the side of the slag bin by the filter screen frame and the filter screen net, water in the slag material flows out from the slag material under the action of gravity and extrusion and flows out through meshes of the filter screen net, enters a cavity at the other side isolated by the filter screen net, and water in the cavity is discharged to a designated position through a drainage pipe. And after the water-containing slag material is placed in the slag bin for a period of time, the slag bin can be discharged after the water content requirement is met.
(2) After a period of use, in order to prevent the filter plate net from being blocked and ensure the wet slag dewatering effect, the filter plate net needs to be backwashed. And the back flush valve is opened, and the back flush medium sequentially passes through the back flush pipeline and the back flush spray pipe and finally is sprayed out from the back flush spray nozzle to flush the filter plate net, so that the back flush effect is good.
The backwash anti-blocking type slag bin water filter has the advantages that when the filter plate net is used for a long time and is worn or blocked seriously, the filter screen frame can be taken out by loosening the upper cover plate bolt and taking down the upper cover plate, so that the filter screen frame is convenient to take out, replace or clean.
According to the backwash anti-blocking slag bin water filter, the backwash spray pipe cover plate adopts the backwash spray pipe cover plate bolt connection structure, so that the backwash spray pipe assembly is easy to detach and convenient to maintain.
The backwash anti-blocking slag bin water filter has good sealing performance due to the sealing element arranged between the upper cover plate and the flange seat.
The back flushing anti-blocking slag bin water filter can be made of water, air or steam.
The backwash anti-blocking slag bin water filter can comprehensively utilize the dewatered slag as a building material.
In conclusion, the back flushing anti-blocking slag bin water filter has the advantages of good back flushing effect, prevention of blocking of a filter plate net, convenient taking out, replacement or cleaning of the filter plate net, easy disassembly and maintenance of a back flushing spray pipe assembly, good sealing performance, and capability of comprehensively utilizing the slag after water removal as a building material.
