Abstract
The utility model discloses a concrete slurry main building circulating pipeline which comprises a circulating pipeline body. The circulating pipeline body is connected with a water pump and provided with a measuring butterfly valve and a measuring hopper. The concrete slurry circulating pipeline is characterized in that a vent pipe is arranged on the circulating pipeline body. Compared with the prior art, after the vent pipe is arranged on the circulating pipeline body, when the measuring butterfly valve is opened, air is supplied in the pipeline body rapidly so that the discharging speed of the butterfly valve can be effectively accelerated, and when the water pump stops operation, the slurry returning speed in the pipeline body can be effectively accelerated.
Description
Technical field
The utility model relates to a kind of concrete pulp-water main building circulation loop.
Background technique
Concrete mixing plant washes stirrer every day, transport vehicle will spend a large amount of water, and the pulp-water of these flushing devices arbitrarily discharging pollutes the environment.In addition, using clear water flushing transport vehicle also is a very big waste, supposes the water of 1～2 ton of transport vehicle water of flushing, will wash every day 2～3 times.Use 20 transit mixers to be example every day with a tame medium scale mixing plant, one day will water 40～120 tons.In view of this, the recycling of pulp-water is concrete mixing plant environmental protection and conserve water resources effective approach.Therefore, domestic many mixing plants mostly begin to introduce and use remaining water-bearing concreae recovery plant, and the contained sandstone of the pulp-water of flushing device, slime water are separated respectively, are used further to concrete production.Pulp-water after the separation enters stirring pool, the stirrer resting period property running in the stirring pool, the uniformity of maintenance slime water.When producing concrete, slime water uses in the ratio cumulative measurement that the laboratory provides with clear water by the control of main building circulation loop.
During the metering slime water, need open the metering butterfly valve in the main building circulation loop, allow slime water enter weighing hopper.At this moment, the pipeline of butterfly valve rear end can produce the part pull of vacuum, causes most of slime water still to flow through from pipeline, has only small part to flow out from butterfly valve, thereby has influenced slime water metering speed greatly.
In addition, when water pump shut down, slime water flowed back to stirring pool respectively certainly from the pipeline two ends, also can produce pull of vacuum in the middle of the pipeline, thereby influence the slime water back-flow velocity.
The model utility content
The utility model provides a kind of concrete pulp-water main building circulation loop in order to solve the above-mentioned deficiency of prior art, when the metering butterfly valve is opened, can effectively speed the butterfly valve discharge rate, when water pump shuts down, can accelerate the pulp-water back-flow velocity in the pipeline.
Above-mentioned purpose of the present utility model realizes by following technological scheme: a kind of concrete pulp-water main building circulation loop, comprise circulation loop, described circulation loop connects a water pump, and circulation loop is provided with metering butterfly valve and weighing hopper, and it is characterized in that: described circulation loop is provided with permeability cell.
Described metering butterfly valve top is provided with service valve, in case the metering butterfly valve stops up, opens service valve, can clear up the metering butterfly valve.
Described circulation loop comprises watering pipeline and return line.
The utility model advantage compared with prior art is: after circulation loop is provided with permeability cell, when the metering butterfly valve is opened, can carry out tonifying Qi to pipeline rapidly, thereby effectively accelerate the discharge rate of butterfly valve, when water pump shuts down, can effectively accelerate the pulp-water back-flow velocity in the pipeline.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is traditional circulation loop and fundamental diagram.
Fig. 3 is fundamental diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, a kind of concrete pulp-water main building circulation loop comprises circulation loop 1, and described circulation loop 1 connects a water pump 2, and circulation loop 1 is provided with metering butterfly valve 3 and weighing hopper 4, and it is characterized in that: described circulation loop 1 is provided with permeability cell 5.Described metering butterfly valve 3 tops are provided with service valve 6, in case metering butterfly valve 3 stops up, open service valve 6, can clear up metering butterfly valve 3; Described circulation loop 1 comprises watering pipeline 11 and return line 12.
During production, water pump 2 is opened, and pulp-water is extracted into the stirring main building by watering pipeline 11 from stirring pool 7, flows back to stirring pool 7 by return line 12 again.Form a circulation loop 1.
Traditional circulation loop as shown in Figure 2, when needs added pulp-water 8 ' toward weighing hopper 4 ', metering butterfly valve 3 ' was opened.Can form a parital vacuum suction in this thing circulation loop, cause most of pulp-water 8 ' still from return line 12 ', to flow out, thereby influence the discharge rate of metering butterfly valve 3 '.
As shown in Figure 3, in circulation loop of the present utility model, when needs added pulp-water 8 toward weighing hopper 4, metering butterfly valve 3 was opened.Can form a parital vacuum in this thing pipeline.Because having increased permeability cell 5 in the pipeline newly, when metering butterfly valve 3 is opened, can carry out tonifying Qi to pipeline rapidly, offset the pull of vacuum in the pipeline, thereby effectively speeded the discharge rate of metering butterfly valve 3.In addition, when water pump 2 shuts down, can effectively speed pulp-water 8 back-flow velocities in the pipeline.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses do anyly be equal to change or modify, all fall into the scope that this patent comprises.
