Detailed Description
An exemplary embodiment of the present utility model will be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the utility model are shown. Unless defined otherwise, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art.
As shown in fig. 1 to 3, the kitchen waste slurry sand removing device of the present embodiment includes a sand setting overflow hopper 1 and a venturi nozzle 3; the sand setting overflow hopper 1 is arranged in the slurry pond 2, kitchen waste slurry is stored in the sand setting overflow hopper 1, the sand setting overflow hopper 1 is small in size and can be placed at a proper position in the slurry pond 2 at will, and the sand setting overflow hopper is generally placed at a liquid inlet of the slurry pond 2. The bottom of the sand setting overflow hopper 1 is an inclined plane so that the sand setting can be gathered to a cone bottom sand outlet of the sand setting overflow hopper 1. The left side air inlet of venturi nozzle 3 is linked together with air inlet steel pipe 5 through a section of small cross section steel pipe 4 that admits air, and the inner chamber of venturi nozzle 3 is stretched into to small cross section steel pipe 4 that admits air, and the upper end of venturi nozzle 3 advances sand mouth 6 and the awl end of sand overflow hopper 1 and goes out the sand mouth and be linked together, advances sand mouth 6 and is the funnel type, and the sand of being convenient for falls into venturi nozzle 3, and air inlet steel pipe 5 and mixed material steel pipe 7 upwards extend out thick liquid pond 2, and air compressor is connected to the end of air inlet steel pipe 5, and the end of mixed material steel pipe 7 connects to the sand collecting device.
The air inlet steel pipe 5 is provided with a manual ball valve 8 for controlling the opening and closing of the compressed air.
In this example, the pipe diameter of the small-section air inlet steel pipe 4 is smaller than the pipe diameters of the air inlet steel pipe 5 and the mixed material steel pipe 7, the pipe diameter of the small-section air inlet steel pipe 4 is 7.5mm, the pipe diameter of the air inlet steel pipe 5 is 25mm, and the pipe diameter of the mixed material steel pipe 7 is 38mm. When the compressed air passes through the reduced flow cross section, the phenomenon that the flow speed of the compressed air is increased is generated, the flow speed of the compressed air is inversely proportional to the flow cross section, the increase of the flow speed is accompanied with the decrease of the fluid pressure, so that the adsorption effect is generated, and a large amount of settled sand is adsorbed by the compressed air to be continuously conveyed backwards.
The sand setting overflow hopper 1 is supported in the slurry tank 2 through four supporting legs, and the supporting legs play a supporting role on the sand setting overflow hopper 1.
The inside of the sand setting overflow hopper 1 is provided with a flow baffle plate, so that when the slurry flow is large, the bottom sand setting is prevented from being impacted.
The sand setting overflow hopper 1 of the embodiment is deeper, and the overflow speed is controlled slowly, so that sand in slurry can be settled to the bottom of the sand setting overflow hopper 1, and the separation effect is realized.
The working principle is as follows:
the kitchen waste slurry enters the sand setting overflow hopper 1, after the slurry is fully stored in the sand setting overflow hopper 1, the liquid overflows, the sand setting gradually settles to the bottom of the sand setting overflow hopper 1, and as the bottom is of an inclined design, the sand setting is collected to a cone bottom sand outlet of the sand setting overflow hopper 1 and then enters the upper sand inlet 6 of the venturi nozzle 3; simultaneously, the compressed air is introduced into the air inlet steel pipe 5, and enters the venturi nozzle 3 through the small-section air inlet steel pipe 4 to generate adsorption, and the compressed air carries a large amount of sand setting to enter the mixed material steel pipe 7 and is conveyed out of the slurry pool 2 together.
