Abstract
The utility model provides a device for automatically desanding from the sand washing liquid, comprising a primary swirler, a secondary swirler, a sand accumulating tank, a water tank, a worm conveyor, an electric motor, and a pipeline. The utility model is characterized in that the sand accumulating tank on the lower part of the primary swirler and the secondary swirler is positioned between the worm conveyor and the water tank; the sand accumulating tank is connected with the feed inlet at the lower part of the worm conveyor; the electric motor is connected with the worm conveyor. The utility model has the advantage that the solid-liquid separation is thorough; the sand after dewatering is automatically exhausted to the ground surface; the sand washing liquid can be circularly used; the water source is saved; the operation is simple; the site is clean; the working efficiency is raised.
Description
Technical field
The utility model relates to a kind of desanding sand removing device, belongs to petroleum industry operation field, particularly suitable sand cleaning fluid sand removing process using.
Background technology
Each elephant of China enters the middle and later periods of exploitation in succession at present, and the sand production problem is on the rise, and the means that solve down-hole casing inner product sand mainly are to utilize sand washing operation sediment outflow.In the process of sand washing, a large amount of load fluid bodies return ground, if directly discharging can cause serious pollution to environment, as if not treated and utilize the direct cycle operation of non-airtight tank, a large amount of sand to be refilled in the well, cause the failure of sand washing operation.
The utility model content
Technical problem to be solved in the utility model provides the automatic desanding sand removing device of environment-friendly type that sand cleaning fluid can be recycled.
In order to solve the problems of the technologies described above, the utility model is achieved in that the upper outlet of one-level cyclone is connected with the inlet of second cyclone by pipeline, and the following outlet of one-level cyclone communicates with long-pending sandbox; The upper outlet of second cyclone communicates with water tank by pipeline, and the following outlet of second cyclone communicates with long-pending sandbox; The top of helical conveyor is provided with sand removing hole, and the bottom of helical conveyor is provided with feeding mouth, and the feeding mouth of helical conveyor bottom links to each other with long-pending sandbox; Motor is connected with helical conveyor.
Above-mentioned long-pending sandbox is arranged between helical conveyor and the water tank.
Above-mentioned one-level cyclone outlet down is provided with first lower cone, and the following outlet of second cyclone is provided with second lower cone, and first lower cone is connected with the top of long-pending sandbox respectively with second lower cone.
Above-mentioned second cyclone can be set to two.
The inlet of above-mentioned one-level cyclone is connected with pipeline.
Advantage of the present utility model and effect are as follows:
Separation of Solid and Liquid is thorough, and the sand after the dehydration is discharged to ground automatically, and sand cleaning fluid can recycle, and saves the water source, and simple to operate, cleaned in situ has improved operating efficiency.
Concrete structure of the present utility model is provided by the following drawings and embodiment.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1: structural representation of the present utility model.
