Abstract
The utility model relates to a back-washing filter, which is suitable for sewage treatment in a petroleum industry, a chemical industry, a light industry, etc. The utility model has the structure that the utility model comprises a cylinder body (8), a sewage inlet pipe (9) which is connected with the cylinder body, a waste material discharge mouth (6), a filter core body (5), a filter liquor discharge pipe (3) and a control valve; the utility model also comprises a back-washing device, and the device is provided with a back-washing pipeline (13) and an automatic control valve (2) which is connected with the back-washing pipeline; one end of the back-washing pipeline (13) is communicated with the filter liquor discharge pipe (3), and the other end is provided with a nozzle (11), and the nozzle is arranged on a cavity body of the filter core body (5). The utility model has the advantages of long service life, wide application, automatic back flushing without stopping, etc., and is existing ideal automatic cleaning device of the petroleum industry, the chemical industry and the light industry.
Description
Technical field
The utility model is a kind of backwash filter that is suitable for industry sewage disposals such as oil, chemical industry and light industry.
Background technology
At present, in industries such as oil, chemical industry and light industry, there is use " basket filter " to carry out sewage disposal.Basket filter is by cylindrical shell 8 and the sewage inlet pipe 9, trash discharge mouth 6, filtering core 5, the filtrate discharge pipe 3 that are attached thereto, and control valve is formed (referring to accompanying drawing).This equipment is not owing to be provided with the device that filtering core is cleaned, thereby has following defective: the one, and maintenance capacity is big, needs at set intervals with manually cleaning; The 2nd, inconvenient, need pull down filtering core during cleaning, and then install; The 3rd, during maintenance, damage filtering core easily, thereby cost is improved; The 4th, influence is produced, and usually needs to shut down filtering core is cleaned.
Summary of the invention
Technical problem to be solved in the utility model is: the backwash filter that a kind of automatic cleaning filtering core is provided, under dead ship condition not, it utilizes the liquid after self filtering to carry out backwash, makes filtering core and even entire equipment be in good working order.
The technical scheme that its technical problem that solves the utility model adopts is such; Comprise cylindrical shell and the sewage inlet pipe, trash discharge mouth, filtering core, the filtrate discharge pipe that are attached thereto, and control valve.Also comprise back purge system, the autocontrol valve that this device is provided with a backwash pipeline and is attached thereto; Backwash pipeline one end is communicated with the filtrate discharge pipe, and the other end is provided with nozzle, and nozzle is positioned at the top of filtering core cavity.
The utility model long service life is not shut down automatic cleaning and filtering core body; Can select different filtering cores to use, the filtering accuracy scope is big, and flow can satisfy different requirements; Simultaneously, simple in structure, cost is low, maintenance is installed conveniently, be widely used, and be comparatively ideal automatic cleaning machine in current oil, chemical industry and the light industry.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing
Structure of the present utility model is as shown in drawings: comprise cylindrical shell 8 and the sewage inlet pipe 9, trash discharge mouth 6, filtering core 5, the filtrate discharge pipe 3 that are attached thereto, and control valve.Also comprise back purge system, 2 autocontrol valves 2 that this device is provided with a backwash pipeline 13 and is attached thereto.Backwash pipeline 13 1 ends are communicated with filtrate discharge pipe 3, and the other end is provided with nozzle 11, and nozzle is positioned at the top of filtering core 5 cavitys.Filtering core 5 oral areas are connected with sealing ring 4.
In the above-mentioned autocontrol valve 2, there is 1 to be connected, with the backwash frequency of control filtrate with timer 1.Sewage inlet pipe 9 is equipped with control valve 10, and its body connects cylindrical shell 8 by flange.Cylindrical shell 8 is provided with seal cover 12.
The utility model is installed on the pipeline of continuous operation, its operation principle is: open control valve 10, effluent stream flows in the cylindrical shell 8 through sewage inlet pipe 9, after core body 5 filters after filtration, its filtrate relies on the hydraulic pressure in cylindrical shell 8 to flow out to the equipment of rolling off the production line through filtrate discharge pipe 3, and the dirt that filters is owing at the bottom of gravity falls into tin.When filtering core 5 need be cleared up by timer 1 official hour, 2 autocontrol valves 2 were opened, simultaneously closed control valve 10.Under liquid in pipe pressure, filtrate is flowed out through the nozzle 11 of backwash pipeline 13, and nozzle does not stop rotation for 360 ° in the clean side of filter core, spray laminar flushing liquor, to the filter core backwash, make the dirt removal that stops up the filter core eyelet, this dirt is also because at the bottom of gravity falls into tin.Open valve 7, the dirt of tube at the end discharged through trash discharge mouth 6.Like this, just reached the purpose of the cleaning filtering core that do not stop.Cleaning finishes, and all valves reset.Reciprocal according to this, this machine filters, backwash work.
Claims (2)
1. backwash filter, the sewage inlet pipe (9) that comprises cylindrical shell (8) and be attached thereto, trash discharge mouth (6), filtering core (5), filtrate discharge pipe (3), and control valve, it is characterized in that also comprising back purge system, the autocontrol valve (2) that this device is provided with a backwash pipeline (13) and is attached thereto, backwash pipeline (13) one ends are communicated with filtrate discharge pipe (3), and the other end is provided with nozzle (11), and nozzle is positioned at the top of filtering core (5) cavity.
2. backwash filter according to claim 1 is characterized in that autocontrol valve (2) has 2, and wherein 1 autocontrol valve is connected with timer (1).
