Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, the recovery acid solution filtration unit that is used for pipe pickling of the present utility model comprises cavity type tank body 1, is arranged at baffle plate 4 in the tank body 1, goes out acid tube 2, acid inlet tube 3; Described tank body 1 cavity is divided into two portions by baffle plate 4, and wherein a part is a filtering chamber 12 for the sour chamber 11 of storage, another part, cuts off by passing through baffle plate 4 between connecting passage connection, the bottom between sour chamber 11 of described storage and filtering chamber 12 tops; Describedly go out that acid tube 2 is communicated with the sour chamber 11 of storage, acid inlet tube 3 is communicated with filtering chamber 12, be provided with the individual sieve plate 5 that comprises filter screen 52 of n (n 〉=1) in filtering chamber 12, described filtering chamber 12 is divided into the individual filter pocket 13 of n+1 (n 〉=1) by sieve plate 5; Along the acid solution flow direction, the mesh aperture of each sieve plate 5 filter screen 52 successively decreases; Described acid inlet tube 3 is communicated with the filter pocket 13 adjacent with tank body 1 sidewall.
By the setting of baffle plate 4, reclaim acid solution and at first enter filtering chamber 12 by acid inlet tube 3, impurity is subjected to baffle plate 4 to stop that sedimentation, liquid are diffused in the sour chamber 11 of storage by the top connecting passage; Play the choked flow effect by 5 pairs of acid solution liquid of sieve plate stream, thereby reduce the acid solution flow velocity, improve the acid solution fluidised form, reduce the amount of impurities that is driven come-up by liquid stream, accelerate settling efficiency; By the partition effect of sieve plate 5, stop impurity to enter next stage filter pocket 13 simultaneously, can avoid impurity to enter the sour chamber 11 of storage with acid solution greater than corresponding filter screen 52 mesh.Sedimentation filters that filtration yield is big and influenced by foreign matter content little, and filter screen 52 classified filterings have disperseed the influence of foreign matter content, therefore can adapt to the big flow of circulation acid solution, big foreign matter content filters, and avoids pipeline secondary pollution to be cleaned, and good filtration effect.In example as shown in the figure, the tank body that reclaims the acid solution filtration unit directly jar uses as the acid of cycle pickling, goes out that acid tube 2 is connected with sour pump, acid inlet tube 3 is connected with pipe outlet to be cleaned, in the increase filtering function, has guaranteed integrally-built simplification.
Above-mentioned sieve plate 5 can only be made of filter screen 52, but in order to strengthen the choked flow effect of 5 pairs of acid solution liquid streams of sieve plate, thereby further reduce the acid solution flow velocity, improve the acid solution fluidised form, minimizing is driven the amount of impurities of come-up by liquid stream, accelerate settling efficiency, described sieve plate 5 comprises plate body 51 and filter screen 52, and described plate body 51 is fixed on the tank body 1, and plate body 51 bottoms are provided with opening 53, and described filter screen 52 is fixed in plate body 51 and covers plate body 51 openings 53.Reclaim acid solution and enter next stage filter pocket 13 by upper level filter pocket 13 by sieve plate 5 bottom openings 53.
The mesh aperture that quantity, filter screen 52 are set of sieve plate 5 can be provided with according to concrete foreign matter content, size distribution, pipeline cleaning requirement etc.In example as shown in the figure, be provided with two sieve plate 5, the mesh aperture of sieve plate 5 filter screens 52 adjacent with tank body 1 sidewall is 5mm, the mesh aperture of sieve plate 5 filter screens 52 adjacent with baffle plate 4 is 2mm.
When reclaiming acid solution filtration unit works better, reclaim acid solution and at first enter filtering chamber 12 by acid inlet tube 3, impurity is subjected to baffle plate 4 to stop that sedimentation, liquid are diffused in the sour chamber 11 of storage by the top connecting passage, stores up acid solution in the sour chamber 11 and is extracted out its liquid level by sour pump and be lower than acid solution liquid level in the filtering chamber 12.Therefore, the acid solution liquid level in filtering chamber 12 each filter pocket 13 maintains an equal level with the connecting passage bottom at least, and therefore in order to guarantee the filtration step by step of 5 pairs of acid solutions of sieve plate, described sieve plate 5 highly is higher than the connecting passage bottom.
Because the variation that the fluctuation of acid solution flow, impurity stop up filter screen 52 situations, acid solution liquid level between each sieve plate 5 in the filter pocket 13 is fluctuation, and want the height of precise definition sieve plate 5 to cover sieve plate 5 thoroughly to avoid acid solution, computation process is comparatively complicated.Therefore, further, described sieve plate 5 plate bodys 51 tops link to each other with tank body 1 end face respectively, can avoid each filter pocket 13 interior acid solution to cover adjacent sieve plate 5 fully and diffuse in the adjacent filter pocket 13.
Acid solution is diffused in the sour chamber 11 of storage by the top connecting passage, acid solution in upper level filter pocket 13 is being stored up in the sour chamber 11 through directly diffusing in behind the filter screen 52, further, highly be lower than the height of connecting passage bottom with plate body 51 openings 53 of baffle plate 4 adjacent sieve plate 5.
Further, play the filtering effect of sedimentation simultaneously in order to guarantee filter pockets 13 at different levels, further strengthen the choked flow to liquid stream, reduce the impurity level with liquid stream come-up, along the acid solution flow direction, each plate body 51 opening 53 highly successively decreases.
In order further to improve the acid solution fluidised form, avoid liquid stream to directly the washing away of filter screen 52, described acid inlet tube 3 is with the setting of staggering of the opening 53 of adjacent sieve plate 5 with tank wall.
The connecting passage that sour chamber 11 and filtering chamber 12 are stored up in above-mentioned connection can be made of through hole, the window on baffle plate 4 tops, and is concrete for simplified construction, is provided with the gap between described baffle plate 4 and tank body 1 end face, and constitutes connecting passage by described gap.
