Description

Self-discharging type sand storage and supply box for oil field fracturing

Technical Field

The utility model relates to an oil field fracturing field, a self-discharging formula is stored up and is supplied sand box for oil field fracturing specifically says so.

Background

The hydraulic fracturing technology has been developed for many years, and with the progress of the fracturing technology, the requirements on fracturing equipment are higher, the requirements on discharge capacity and pressure are continuously improved, and a new height is provided for continuous liquid injection amount. The existing fracturing sand storage and transportation modes comprise a large-scale sand truck, sand bag storage and transportation and the like, the large-scale sand truck is suitable for small-scale fracturing, and has good maneuverability, and the defect that continuous large-displacement operation requirements are difficult to guarantee due to transportation distance, road conditions and the like. Therefore, large fracturing is usually carried to the site in advance according to the required sand amount in the preparation work in the previous period, and the large fracturing is transported to a sand hopper of an automatic sand storage and supply device through equipment such as a hoisting device and a forklift on the site along with the work, so that the blanking efficiency is improved for ensuring the continuity of the operation, the sand bag is punctured, the sand bag becomes a disposable consumable, and the sand bag cannot be reused, so that waste and environmental pollution are caused.

SUMMERY OF THE UTILITY MODEL

In order to overcome current fracturing sand warehousing and transportation sand package repeatedly usable and cause extravagant not enough, the utility model provides an oil field fracturing is with self-discharging formula storage and supply sand box, this oil field fracturing is with self-discharging formula storage and supply sand box repeatedly usable has solved the problem that the on-the-spot sand material of fracturing is stored, the transportation work load is big, work efficiency hangs down, makes the more safe environmental protection of fracturing site operation.

The technical scheme of the utility model is that: the utility model provides an oil field fracturing is with self-discharging formula storage confession sand box, includes sand box frame, and sand box frame periphery is fixed with sand box board, it has into sand mouth to open on sand box frame's the sand box roof, is connected with into sand mouth door on advancing sand mouth, and it has the blanking mouth to open on sand box frame's the sand box bottom board, and blanking mouth department is connected with the blanking door, and blanking door bottom both sides are fixed with horizontal guide way.

The two sides of the blanking port on the bottom plate of the sand box are provided with inclined sand ladder plates.

The blanking door is formed by splicing two door sealing plates A and two door sealing plates B, and the edges of the door sealing plates A and the door sealing plates B are connected to the sliding track.

The utility model discloses following beneficial effect has: by adopting the scheme, the sand storage and supply box adopts a self-unloading structure, so that the defects of low efficiency and serious waste of a blanking mode for puncturing sand bags are overcome, the cost is saved for users, and the sand storage and supply box is safe and environment-friendly; the device is suitable for on-site storage, transportation and rapid discharge, is suitable for continuous and large-discharge fracturing operation, not only solves the problem of large storage and transportation workload commonly used in domestic fracturing operation, but also greatly improves the fracturing operation efficiency; the self-unloading storage and supply sand box has safe and reliable quality, can be used repeatedly and has long service life.

In the figure, 1-a sand inlet door, 2-a lifting lug, 3-a sand box side plate, 4-a sand box frame, 5-a sand box panel, 6-a sand box bottom plate, 7-a horizontal guide groove, 8-a sand ladder plate, 9-a sliding rail, 10-a blanking bin door, 101-a door sealing plate A, 102-a door sealing plate B and 103-a bin door frame.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1 to 5, the self-unloading sand storage and supply box for oilfield fracturing comprises a box frame 4, sand box plates 5 are fixed on the periphery of the box frame 4, a box top plate is fixed on the top of the box frame 4, a box bottom plate 6 is fixed on the bottom of the box frame 4, and lifting lugs 2 are fixed at four corners of the top of the box frame 4. The sand box top plate is provided with a sand inlet, the sand inlet is connected with a sand inlet door 1, the center of the sand box bottom plate 6 is provided with a blanking port, the blanking port is connected with a blanking bin door 10, and two sides of the bottom of the blanking bin door 10 are fixed with horizontal guide grooves 7. The blanking port is characterized in that a bin gate frame 103 is fixed on the periphery of the upper portion of the blanking port, the bin gate frame 103 is fixed on the sand box frame 4, a sliding track 9 is fixed on the bin gate frame 103, the blanking bin gate 10 is formed by splicing two gate sealing plates A101 and two gate sealing plates B102, the edges of the gate sealing plates A101 and the gate sealing plates B102 are connected to the sliding track 9, and the middle portions of the gate sealing plates A101 and the gate sealing plates B102 are inclined upwards. The both sides of blanking mouth are equipped with the sand step board 8 of slope on the sand box bottom plate 6, and the one end tilt up that blanking door 10 was kept away from to sand step board 8 to can be the sand material landing of blanking mouth department naturally in the sand box.

The blanking bin gate 10 is in a closed state all the time in the sand conveying process, in the fracturing sand adding operation process, the sand inlet gate 1 is firstly opened, the whole sand box is filled with sand materials, the sand inlet gate 1 is closed, the sand is transported by the lifting lug 2 or the horizontal guide groove 7, and the sand is lifted to a blanking platform of the sand storage device. During the field operation, utilize and supply the stop device on the sand storage equipment, can make this supply the blanking door 10 center department of sand case correspond to the blanking platform center that supplies the sand storage equipment, supply the sand box to move down wholly this moment, because the size of blanking platform is less than the size of blanking door 10, four door shroudings of blanking door 10 are backed down, simultaneously because the angle slope of the sand terraced board 8 of two symmetries and door shrouding arranges, all sands in the incasement can all be because the action of gravity unloads to the user equipment from the blanking mouth, the completion adds the sand.
