The filter material filter of the invention has the advantages of good effects of oil removing, slag removal and backwash, the conservation of the filter material, high degree of automation, etc.
Description
Technical field
The present invention is applied to be used for the environmental protection field to handle the more former water of suspension and a kind of filtering material filter of key equipment of circulating water supply system.
Background technology
At present, be applied in the problem that the filtering material filter in the environmental protection field exists: the filter plate of 1 support filtrate is supported on the bracket of tank body (span is big, and rigidity is bad), and the centre adds a large amount of pillars (too much influence the water yield and water flow uniformity).The filtrate of 2 filter plate Filter head type filters is near the normally quartz sand (particle diameter is little, stops up the filter slit) of clearance type filter.3 backwash water outlet tank sheets are bent into (filtrate flows away together with water).The control device of 4 no backwash liquid level height (backwash aqueous vapor intensity is big more, and filtrate runs off serious more).
Summary of the invention
The objective of the invention is to design a kind of filtering material filter, effectively solve the problem that existing filtering material filter exists.The filter plate support adopts I-steel and adds the support beam structure of a small amount of support column down, fully guarantees the rigidity of filter plate, prevents filter plate distortion race material, simultaneously the backwash water good fluidity.The filtrate of close clearance type filter adopts the cobble bed course of certain particle size, increases the even flowability of filter saturating crack rate and aqueous vapor.The backwash effluent trough is set up buffer-type damping spacer assembly, can add big reverse washing intensity, stops the loss of filtrate.The backwash liquid level is just set up the liquid level oscillation control device, cooperates with the electrical equipment control servo-drive system, allows backwash water in the vibration of the boundary layer place of delivery port, and despumation stops filtrate to run off.
Implementation method of the present invention: the big rigidity supporting construction of described filter plate, be to adopt road, three roads to five filter plate support I-steel and filter plate and cylindrical shell assembly welding firm in the filter plate support, be welded on the low head with filter plate support column bottom, the top overhead welding supports under the I-steel at filter plate again.
Described cobble filter material layer is at the cobble filtrate that adopts (200-300) mm of (4-12) mm granularity near the filtrate of clearance type filter.
Described liquid level oscillation control device is to connect in backwash effluent trough delivery port place to go up the high buffer-type damping spacer assembly of 500mm; Weld fixedly liquid level oscillation control device on upper cover, extraction and feedback backwash liquid level are just given the electrical equipment control servo-drive system.

The specific embodiment
In conjunction with Figure of description detail and the working condition that the present invention proposes elaborated.
The working condition of a kind of filtering material filter of the present invention as shown in Figure 1, when the sewage that contains a certain amount of suspension or oil, be distributed on the filter material layer (8) of the variety classes specification on the big rigidity supporting construction of forming by low head (2) filter plate support column (3) filter plate support I-steel (4) filter plate (5) clearance type filter (6) in the filtering material filter equably by cloth tank (11) buffer-type damping spacer assembly (12) with certain flow velocity (10～20～40) m/h, suspension and oil are blocked by filter material layer and are adsorbed, and the water filter (6) that contains trace impurity (meeting the requirements) leaches to utilize again; For filter is recycled for a long time, filter is provided with reverse cleaning filtrate, makes the abundant regenerating unit of filtrate.The backwash water reverse flow is cooperated with electrical apparatus control system is servo by buffer-type damping spacer assembly (12) and liquid level oscillation control device (10), bottles up filtrate, takes away impurity.
The big rigidity supporting construction of the filter plate of filtering material filter of the present invention as shown in Figure 2, (3 are welded on the low head (2) the filter plate support column, top is fixed on filter plate and supports under the I-steel (4), and I-steel and filter plate (5) and tank body (7) are welded to each other fixing, form big rigidity supporting construction.
The cobble filtrate of the maximum efficiency of filtering material filter of the present invention protection filter as shown in Figure 3, clearance type filter (6) is fastened on the filter plate (5), cobble filtrate (8) homogeneous reactor cloth is on filter plate and filter.
The buffer-type damping spacer assembly and the cloth tank of filtering material filter of the present invention are used in combination as shown in Figure 4, and buffer-type damping spacer assembly (12) is fixed on cloth tank (11) and goes up acting in conjunction, stop filtrate to run off.
The liquid level oscillation control device of filtering material filter of the present invention cooperates as shown in Figure 5 with the electrical equipment control servo-drive system, liquid level oscillation control device (10) is fixed on the upper cover (9), probe reaches the backwash liquid level and extracts signal, feed back to the electrical equipment control servo-drive system, ringing, reach backwash water in the vibration of the boundary layer place of delivery port, despumation stops filtrate to run off.
