Abstract
The utility model relates to a plate and frame type filter press capable of improving the filter pressing effect, which comprises a filter press body, wherein a back washing liquid inlet pipe is connected on a filtrate outlet pipeline of the filter press in parallel, a back washing liquid drainage pipe is connected on a feed pipeline of the filter press in parallel, and stop valves are respectively arranged on the back washing liquid inlet pipe and the back washing liquid drainage pipe. By carrying out periodical back washing on filter cloth, the filtration capacity of the plate and frame type filter press can be recovered, so that the filtration effect of the filter press can be improved, and the filter pressing working efficiency is high; furthermore, the structure is simple, and the operation is convenient.
Description
Technical field
The utility model relates to a kind of plate and frame type filter-press, specifically a kind of plate and frame type filter-press that improves the press filtration effect.
Background technology
Plate and frame type filter-press adopts and mechanical, electrical, liquid integratedly to manufacture and design, and can realize compressing automatically, filters, squeezes, unclamps, a series of automation processes such as arm-tie, the press filtration high efficiency.Yet in the process of using, especially in the ultra-fine material of press filtration, material can cause to a certain degree obstruction to filter cloth, and therefore along with the filter cloth prolongation of service time, the effect of squeezing can decrease, and the press filtration operating efficiency decreases, and has a strong impact on production capacity.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art part, and a kind of plate and frame type filter-press that improves the press filtration effect is provided, and can stablize the result of use of filter cloth, promotes production efficiency.
For achieving the above object, the utility model has adopted following technical scheme: comprise the filter press body, be parallel with the backwash feed tube on the filtrate (liquid pipeline of filter press, be parallel with the backwash discharging tube on the feed pipe of filter press, on backwash feed tube and the backwash discharging tube stop valve be housed respectively.
Counter-flushing liquid regularly is delivered in the filter press by the filtrate (liquid pipeline of filter press, and counter-flushing liquid advances filter cloth by the filtrate chamber of filter cloth and oppositely enters in the filter cake chamber, and the feed pipe by filter press is expelled to outside the press filtration again.Counter-flushing liquid cleans filter cloth by filter cloth the time, makes it to recover filter capacity.
As shown from the above technical solution, the utility model makes it to recover filter capacity, thereby can improve the filter effect of filter press by filter cloth being carried out the periodic reverse flushing, the press filtration high efficiency, and simple in structure, easy to operate.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, be parallel with backwash feed tube 11 on the filtrate (liquid pipeline 9 of filter press 5, be parallel with backwash discharging tube 6 on the feed pipe 4 of filter press 5, stop valve 10,7 is housed respectively on backwash feed tube 11 and the backwash discharging tube 6.
During filter press 5 work, the material in the hopper 1 is entered in the filter press 5 by the charging aperture on the filter press 5 51 through feed pipe 4 by feed pump 2, and the filtrate after the press filtration is discharged through pipeline 9 by leakage fluid dram 52,53,54 and 55 respectively.
When carrying out backwash operation, earlier the valve 3,8 on filter press 5 feed pipes 4 and the filtrate (liquid pipeline 9 is closed, open the stop valve 10,7 on counter-flushing liquid feed tube 11 and the discharging tube 6 then, the leakage fluid dram 52,53,54 and 55 of counter-flushing liquid by filter press 5 is delivered in the filter press 5, counter-flushing liquid advances filter cloth by the filtrate chamber of filter cloth and oppositely enters in the filter cake chamber, and it is outer and drain in the counter-flushing liquid accumulator tank through backwash discharging tube 6 to be expelled to press filtration by the charging aperture 51 of filter press 5 and feed pipe 4 again.For preventing impurity and the material reaction on the filter cloth in the counter-flushing liquid and be bonded on the filter cloth that used counter-flushing liquid is a desalted water.
