Description
Technical Field
The utility model relates to a sewage pipeline that is used for concrete mixing plant to take wisdom valve.
Background
Based on the requirement of environmental protection management and control, the concrete mixing plant needs to realize that sewage is not discharged outside. Namely, the sewage can not be discharged to a municipal sewage pipeline and can only be recycled in a station. Therefore, a sewage tank is arranged in the mixing station to store sewage, and the sewage is subsequently used for producing concrete. Due to the limitation of the position of the mixing plant and the position of the sewage tank, most sewage pipelines are long in erection distance, sewage is pumped to the mixing plant by a sewage pump when production is needed, and long time is needed for waiting for sewage when continuous production is needed, so that the production efficiency of concrete is influenced.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model discloses to among the prior art because sewage pipe between sewage jar and the stirring building is too big, when leading to production to need use sewage, the too long problem that influences concrete production efficiency of latency provides a sewage pipe who is used for concrete mixing plant to take the wisdom valve.
The technical scheme is as follows: the utility model discloses a sewage pipeline with a smart valve for a concrete mixing plant, one end of the sewage pipeline is connected with a sewage tank, and the other end of the sewage pipeline is connected with a concrete mixing plant; along the positive flowing direction of sewage, a through pipe is arranged at the rear end of the sewage pump in the sewage pipeline, and the left end and the right end of the through pipe are respectively and fixedly connected with the sewage pipeline on the corresponding side; a water flow sensor and a butterfly valve are arranged in the through pipe, and a timer and a pneumatic actuator are fixed on the outer side wall of the through pipe; the sewage pump, the water flow sensor, the timer and the pneumatic actuator are respectively connected with an external PLC control box through signal lines, the pneumatic actuator is externally connected with an air compressor to supply air, and the pneumatic actuator drives the butterfly valve to open and close through air pressure.
Wherein, the sewage pipeline and the horizontal plane's contained angle a is greater than 0.
Wherein the inner diameter of the through pipe is not larger than the inner diameter of the sewage pipeline.
Has the advantages that: by adopting the sewage pipeline of the utility model, when the stirring building is continuously produced, a certain amount of sewage is stored in the sewage pipeline, so that the sewage can be quickly supplied when the stirring building is weighed again, and the sewage does not need to wait for a long time, thereby effectively solving the problem that the sewage is slowly supplied by a long-distance sewage pipeline; meanwhile, if the sewage stored in the sewage pipeline is not used within the set time, the sewage stored in the sewage pipeline can be returned to the sewage tank, so that the situation that the pipeline is blocked due to the long-time standing and precipitation of the sewage in the pipeline is avoided.

fig. 2 is a schematic diagram of the structure of the through pipe.
Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-2, the utility model is used for a sewage pipeline with a smart valve of a concrete mixing plant, the included angle a between the sewage pipeline 7 and the horizontal plane is more than 0 degree, one end of the sewage pipeline 7 is connected with a sewage tank, and the other end is connected with a concrete mixing plant; along the positive flowing direction of sewage, a sewage pipeline 7 is provided with a through pipe 1 at the rear end of a sewage pump 8, and connecting parts 9 at the left end and the right end of the through pipe are respectively fixedly connected with sewage pipelines (7-1,7-2) at the corresponding sides; a water flow sensor 2 and a butterfly valve 6 are arranged in the through pipe 1, and a timer 3 and a pneumatic actuator 5 are fixed on the outer side wall of the through pipe 1; the sewage pump 8, the water flow sensor 2, the timer 3 and the pneumatic actuator 5 are respectively connected with an external PLC control box through signal lines, the pneumatic actuator 5 is externally connected with an air compressor for air supply, and the pneumatic actuator 5 drives the butterfly valve 6 to open and close through air pressure. The inner diameter of the through pipe 1 coincides with the inner diameter of the sewage pipe 7. The water flow sensor 2 is used to detect the direction of the water flow in the through duct 1.
Sewage is pumped into the sewage pipeline 7 from the sewage tank through the sewage pump 8, when the sewage flows through the through pipe 1, the butterfly valve 6 is in an open state along with the starting of the sewage pump 8 at the moment, when the stirring building normally weighs the sewage, the sewage continuously passes through the through pipe 1, when the sewage needs to be stagnated and supplied in the middle, the sewage pump 8 is stopped, when the sewage pump 8 is suspended, the butterfly valve 6 is closed, at the moment, a certain amount of sewage can be reserved in the rear end region 7-2 of the sewage pipeline in the butterfly valve 6, the sewage can not completely flow back to the sewage tank, when the subsequent stirring building weighs again, the sewage reserved in the sewage pipeline region 7-2 can quickly enter the stirring building, and therefore the continuity of sewage supply is achieved.
When the sewage pump 8 stops working, the timing time set by the timer 3 is 5min, the time is counted from the time when the sewage pump 8 is closed, after five minutes, the timer 3 gives an electric signal to the pneumatic actuator 5 through the PLC control box to drive the butterfly valve 6 to open, and under the action of gravity, sewage in the sewage pipeline 7 flows back to the sewage tank, so that the situation that the sewage pipeline 7 is blocked due to the fact that the sewage is kept stand and deposited in the sewage pipeline 7 for a long time is avoided.
The utility model discloses take sewage pipe of wisdom valve can reach the long-distance sewage of long pipeline and in time carry the purpose, has solved the sewage pipe overlength that erects between stirring building and the sewage jar, the problem of waiting for the sewage time of a specified duration during continuous production can effectively improve the production efficiency of stirring building.
