Description
Technical field
The utility model relates to the pumping concrete construction field, but a kind of equipment that is located at the easy cleaning the reinforcement of concrete on the pump line system particularly.
Background technology
The pumping concrete construction process generally refer to High pressure cement pump and pump line system, by mobility preferably concrete conveyance to appointed area and the work progress that carries out concreting.This work progress often is applied to the concrete pouring construction in Civil Engineering Construction.In construction, common High pressure cement pump is divided into two classes: automotive pump and drag pump.Concrete in this work progress generally adopts the concrete mixing plant commercial concrete of mixing in advance.The commodity coagulation is delivered to job site by concrete mixer after mixing in advance, and then concrete is transfused in High pressure cement pump and carries out operation.Described pump line system is comprised of the single-unit pump line of certain-length, general every joint 2～3m, and between joint and joint, the general flange that adopts is connected (sometimes also can adopt the buckle connection, but the pressure that the flange connection can be born connecting higher than buckle).Use pumping concrete construction to be conducive to improve efficiency of construction, convenient construction.
The work progress of conventional pumping of concrete is as follows: 1, at the construction field (site) near High pressure cement pump of location arrangements of vehicle in and out port; 2, the pump line of arranging moves towards and connects pump line, forms the pump line system; 3, commercial concrete is delivered to job site, carry out the pumping of concrete operation.
After the construction operation of pumping of concrete completes, the concrete cleanup step of High pressure cement pump and pump line system is as follows: 1, concrete pump is shut down; 2, remove the joint pump line near concrete pump, form two outlets (concrete pump is led in an outlet, and another leads to the pump line system); 3, cleaning concrete pump, discharged waste water by outlet; 4, fill in a sponge ball and connect an air pump at the end of pump line system, starting small air pump, the concrete that sponge ball is promoted in pump line refluxes, and from outlet, discharges.
High pressure cement pump has following some problem with the pump line system when clearing up concrete: 1, because the pump line in the pump line system is connected by flange, therefore dismantle pump line (removing the bolt on flange) and need the long period, yet concrete can not stop for a long time in pump line, this is because long-term immobilising concrete can solidify and block pump line, the pump line blocked is difficult to cleaning and time-consuming, so when the cleaning pump line, the time of removing pump line is very limited, requires more than the constructor and constructs skilled; 2, from the view of security, owing in the pump line system, having concrete, if the scope of operation, higher than outlet (such as the scope of operation at certain floor), at the outlet mineralization pressure, causes potential threat to the constructor because of the Action of Gravity Field concrete; 3, the concrete of the discharge after the cleaning can't recycle, and forms discarded object, and the operation number of times is more, and the pump line system is longer, and discarded object is more.
The utility model content
The purpose of this utility model is to provide a kind of pumping of concrete cleaning current divider, solve traditional pumping of concrete manner of cleaning up time-consuming, easily cause pump line to block, can cause potential threat and the too many technical problem of discarded object (discarded concrete) to the constructor.
For achieving the above object, the utility model adopts following technical scheme: a kind of pumping of concrete cleaning current divider, be arranged on outdoor pump line, and it is characterized in that: comprise cleaning current divider body A, cleaning current divider body B and knife gate valve.
The end of described cleaning current divider body A is provided with the circular flange A that is connected use with outdoor pump line, the other end of cleaning current divider body A is connected with the end flanges of cleaning current divider body B with bolt by square flange, flange cushion block, and the other end of cleaning current divider body B is provided with the circular flange B that is connected use with outdoor pump line.
The tube wall of described cleaning current divider body A is provided with current divider outlet A, and the tube wall of described cleaning current divider body B is provided with current divider outlet B, on described current divider outlet A and current divider outlet B, is equipped with the outlet capping.
Described knife gate valve is comprised of knife gate valve valve plate and the knife gate valve hammering handle that is positioned at knife gate valve valve plate two ends, and have the disconnecting link valve opening that a diameter is less than cleaning current divider internal diameter of tube body on the knife gate valve valve plate, described knife gate valve valve plate is clipped in cleaning current divider body A and clears up between current divider body B, square flange and flange cushion block surround in space.
Between described outlet capping and current divider outlet A, the outlet capping exports between B and all can accompany rubber ring with current divider.
Between described outlet capping and current divider outlet A, outlet capping and current divider export and all can be buckle between B and be connected.
Described pumping of concrete cleaning current divider can be located on the outdoor pump line of fertile groove top of job site.
Compared with prior art the utlity model has following characteristics and beneficial effect: the utility model is applied to the pumping concrete construction in building operations, can solve time-consuming, the easy pump line of the manner of cleaning up occurred in the pumping of concrete scale removal process and block, can cause potential threat and the adverse effect such as discarded object is too many to the constructor.
Carry out the concrete prune job by the utility model, can make the efficiency of construction in the unit interval be improved.Specifically, utilize exactly the knife gate valve on the utility model to control concrete flow direction, can be fast enter clean-up phase (without the dismounting pump line from the pumping stage, the less manpower so the bolt on ratio dismounting flange more saves time), therefore greatly reduce the probability that concrete solidifies in pump line, reduce the risk that pump line blocks, also improved greatly constructor's safety guarantee simultaneously.
After having used the utility model, the discarded object (discarded concrete) that cleaning is discharged can directly enter fertile groove (discarded object is filled in fertile groove and belongs to rational utilization), so avoided rehandling, reduced the discharge of discarded object, reduced corresponding environment pollution.
