Drawings
FIG. 1 is a schematic structural view of an automatic sand discharging device of a grit chamber of the present utility model.
In the figure: 1. a sand setting tank; 2. a stirrer; 3. an external pump; 4. a screw pump; 5. an outlet valve; 6. a sand-water separator; 7. a level gauge.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1, the automatic sand discharging device of the grit chamber comprises a grit chamber 1 and a controller, wherein a stirrer 2 and an external discharge pump 3 are arranged at the top of the grit chamber 1, the external discharge pump 3 is a self-sucking pump, the external discharge pump 3 is connected with the bell-type grit chamber through a third pipeline, the bottom of the grit chamber 1 is connected with a screw pump 4 through a first pipeline, an outlet valve 5 is arranged on the first pipeline, the outlet valve 5 adopts a wear-resistant electric butterfly valve for discharging sand water, the screw pump 4 is connected with a sand-water separator 6 through a second pipeline, the sand-water separator 6 is used for separating sand water discharged from the screw pump 4, the grit chamber 1 is provided with a liquid level meter 7, and the stirrer 2, the external discharge pump 3, the screw pump 4, the outlet valve 5, the liquid level meter 7 and the sand-water separator 8 are respectively electrically connected with the controller. The blades of the stirrer 2 are positioned in the pool, and the stirrer 2 is in a normally open state. The controller controls the sand-water separator 6 to run in linkage with the outlet valve 5 and the screw pump 4, and the sand-water separation is processed in real time. The controller outputs high and low liquid level signals according to the collected liquid level data and the user-set high and low liquid level values. The outer drainage pump 3 is used for outer drainage when rivers are great, and when the liquid level value reached high liquid level, outer drainage pump 3 starts the drainage, and when the liquid level is less than low liquid level, outer drainage pump 3 stops the drainage.
The liquid level meter 7 is located in the tank, and the stirrer 2 in the tank runs, so that the water level flows faster, and the traditional floating ball liquid level meter cannot meet the running requirement, so that the ultrasonic liquid level meter is adopted to accurately collect the liquid level in the grit chamber 1.
The normal production flow is as follows: the production post produces and contains sand waste water and discharges into sand basin 1 in with containing sand waste water through pipeline or ditch, and agitator 2 begins to operate, and is even with the silt particle stirring through agitator 2, prevents the caking, influences work flow, on the other hand for the sand water that flows into in the pipeline is even relatively, reduces pipeline jam and wearing and tearing degree, increase of service life. The controller starts the outlet valve 5 and the screw pump 4 according to the process timing water after stirring, and the sand is discharged to the next working procedure for treatment. The sand discharge operation is controlled by the controller to run at regular time according to the process and the sand quantity generated by the production station. The utility model directly discharges the sand-containing wastewater into the grit chamber 1, breaks up the wastewater through the stirrer 2, and pumps the wastewater into the sand-water separator 6 through the bottom screw pump 4 for separation operation. The sand treated by the sand-water separator 6 can be recycled, so that the cost is reduced. When the liquid level value reaches the high liquid level, the external drainage pump 3 starts drainage, and when the liquid level is lower than the low liquid level, the external drainage pump 3 stops drainage, so that the normal operation of the system is further ensured. The utility model has the advantages of small occupied area, high operation efficiency, automatic operation and the like, can be directly arranged near a workshop production line for real-time treatment, changes the rough treatment mode of settling by building a large pool in the past, and saves the operation cost for enterprises.
Although the present utility model has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present utility model.
