Technical field
The utility model relates to the pipe pickling field, and sour device is sent in especially a kind of storage that is used for pipe pickling.
Background technology
Industrial pipeline all needs to clean before use, and the normal at present technology that adopts is online cycle pickling technology.In cleaning process, acid solution send sour device to send constantly in the pipeline to be cleaned by storage, removes the impurity and the stains such as iron rust of inner-walls of duct, and the acid solution of cleaning end conduit then flows back to storage and send sour device to recycle.Storage send sour device to comprise sour jar, acid extracting pipe, return acid tube, send acid tube, sour pump, and acid extracting pipe one end is communicated with the acid jar, the other end is communicated with sending acid tube through sour pump,, storage send sour device respectively by sending acid tube, time acid tube to be communicated with pipeline to be cleaned gangway.
At present, sour pump all is arranged in sour pot bottom or is arranged in parallel with acid jar and is positioned over foundation of civil work or on the ground big, also is that the installation site of sour pump all is lower than the liquid level in the acid jar, so acid extracting pipe, returns acid tube and be full of acid solution for a long time.Cause the sealing of each coupling flange of acid extracting pipe, time acid tube also to cause acid liquor leakage because of washed away by acid solution owing to be full of acid solution in the pipeline for a long time through regular meeting; meanwhile sour pump is mechanical seal; in work and stopping process, all can leak out the part acid solution from sealing; especially after mechanical seal has wearing and tearing slightly; leak more seriously, and the acid solution of revealing can be polluted civil engineering ground, the earth and equipment.
In order to address the above problem, the applicant has applied for that the patent No. is 200920082945.7, denomination of invention is the utility model patent of the online pickler of environmental protection, it is provided with the acid filling disc of cavity type in the position that is higher than sour jar liquid surface, the cavity top of acid filling disc is installed and be positioned to described sour pump by acid filling disc, be communicated with by recovery tube between described acid filling disc cavity and the acid jar.By sour pump being installed in the position that is higher than sour jar liquid surface, having avoided being full of for a long time in the acid extracting pipe acid solution leaks, and the sour leakage that causes of sour pump self mechanical seal leakage, even and leak, the acid solution of leakage also can be returned the acid jar by acid filling disc, recovery tube.But because acid extracting pipe contains a large amount of air, when sour pump is taken out acid, especially when just starting, can't in acid extracting pipe, form vacuum, therefore vaccuum phenomenon often takes place, thereby influence the continuity of pipe pickling work.
The utility model content
Technical problem to be solved in the utility model provides a kind of storage that is used for pipe pickling that can avoid vaccuum phenomenon takes place and send sour device when sour pump installation site is higher than sour jar liquid surface.
The technical scheme that its technical problem that solves the utility model adopts is: sour device is sent in the storage that is used for pipe pickling, comprise the acid jar, acid extracting pipe, return acid tube, send acid tube, the acid pump, described sour pump is installed in the position that is higher than sour jar liquid surface, described acid extracting pipe one end is communicated with the acid jar, the other end is communicated with sending acid tube through sour pump, also be provided with check valve on the described acid extracting pipe, at least one vent valve, be provided with the liquid injection tube of stopping valve, wherein liquid injection tube and vent valve are arranged at respectively on the acid extracting pipe between check valve and the sour pump, and check valve is positioned at below the sour jar liquid surface, and each vent valve all is arranged at the vertex of acid extracting pipe between sour pump and the check valve.
As a kind of preferred, described acid extracting pipe is the L type that comprises horizontal section and vertical section, and wherein horizontal section is positioned at that acid is jar outer, vertical section vertically inserts acid jar.
Further, be provided with a vent valve in the junction of horizontal section and vertical section, described liquid injection tube is arranged at horizontal section.
Further, be provided with vertical acid jar interior longitudinal tubule (L tubule) that inserts, described time acid tube is communicated with sour jar by longitudinal tubule (L tubule).
The beneficial effects of the utility model are: before taking out acid, the stopping valve of opening liquid injection tube injects liquid, open gas in the vent valve vent pipe simultaneously, and stop to inject liquid by check valve and enter acid jar, fill with pipeline after, close the stopping valve of vent valve, liquid injection tube, open sour pump, because therefore full of liquid in the acid extracting pipe between sour pump and the acid jar can avoid taking place vaccuum phenomenon when sour pump installation site is higher than sour jar liquid surface, guarantee the extraction of acid solution.
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, sour device is sent in the storage that is used for pipe pickling of the present utility model, comprise acid jar 1, acid extracting pipe 2, return acid tube 10, send acid tube 11, acid pump 3, described sour pump 3 is installed in the position that is higher than acid jar 1 liquid level, described acid extracting pipe 2 one ends are communicated with acid jar 1, the other end is communicated with sending acid tube 11 through sour pump 3, also be provided with check valve 4 on the described acid extracting pipe 2, at least one vent valve 5, be provided with the liquid injection tube 7 of stopping valve 6, wherein liquid injection tube 7 and vent valve 5 are arranged at respectively on the acid extracting pipe 2 between check valve 4 and the sour pump 3, and check valve 4 is positioned at below acid jar 1 liquid level, and each vent valve 5 all is arranged at the vertex of acid extracting pipe 2 between sour pump 3 and the check valve 4.
