Accompanying drawing explanation
Fig. 1 is functional-block diagram of the present utility model.
Reference character:
1-is containing sand oil-water-gas delivery line, 2-inlet valve, 3-pressure detector, 4-mortar delivery pipe road, 5-oil gas water out pipeline, 6-steam valve, 7-steam pipework.
Embodiment
Below in conjunction with accompanying drawing, by specific embodiment, the utility model is described in further detail.Following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
An automatic sand removal device, it is mainly by the first filtering module, the second filtering module, mortar storage unit, mortar pump, dewatering dirt unit, form containing sand oil-water-gas delivery line 1, mortar delivery pipe road 4, steam pipework 7, oil gas water out pipeline 5; The inlet of the first filtering module and the second filtering module connects respectively containing sand oil-water-gas delivery line, and containing on sand oil-water-gas delivery line, inlet valve 2 is installed at this.The outlet end of the first filtering module and the second filtering module is connected to mortar storage unit by mortar delivery pipe road.First, second filtering module all adopts multistage high flux filter membrane piece, classification filtering different-grain diameter gravel.The entrance point of the first filtering module and the second filtering module and outlet end are all provided with pressure detector 3.The first filtering module, the second filtering module and mortar storage unit are all connected with steam pipework, and steam valve 6 is all set on steam pipework.
