Description

Technical Field

[0001] The utility model relates to the technical field of liquid adding devices, in particular to a liquid adding device for sand mixing equipment. Background Art

[0002] With the advancement of fracturing construction technology, the types and quantities of liquid chemical agents added have also increased, and the number of corresponding liquid addition pumps and pipelines has also increased. Existing sand mixing equipment is generally equipped with 4 or 6 liquid addition pumps, which are generally installed flat on the equipment, occupying a large area, with messy pipelines, difficult to operate and maintain, and the liquid addition pumps and liquid addition pipelines are installed only after the main equipment is assembled, which takes a relatively long time.

[0003] Patent CN214741236U proposes a new type of liquid adding device for sand mixing equipment, which adopts modular design, can be quickly assembled and easy to transport; it adopts vertical combination arrangement, occupies a small area, and is easy to operate and maintain; different media can be pumped in in a multi-channel controllable manner, and the inlets of multiple liquid adding pumps are independent of each other, and can be connected to different liquid supply ends respectively to achieve controllable pumping of different media; the medium can be pumped out in a multi-channel controllable manner to achieve multi-channel output of the medium; it is equipped with a flow meter and a diversion manifold, and is designed with a combination of hard pipes and soft pipes. The main components are connected by hard pipes to facilitate modularization; soft pipes are used to connect to other components for free positioning; a one-way valve is installed at each output position to prevent the medium from flowing back through the sand mixing pipeline.

[0004] The vertical arrangement adopted in the above scheme makes the layout more reasonable, but when multiple liquid adding tanks need to be installed, affected by the overall structure, the liquid adding tanks need to be installed in a surrounding manner along the top of the frame. In this case, when a group of liquid adding pumps is damaged or a section of the pipeline is damaged, it will be difficult to repair due to the limited actual field of vision. The liquid adding tanks need to be disassembled, which will also lead to low maintenance efficiency. Utility Model Content

The utility model has a novel structure. Four groups of liquid adding boxes are slidably installed on the slide rail on the top of the mounting frame. The top is connected to the pipeline assembly through a hose. When it is necessary to move a certain liquid adding box to inspect and repair the pipeline, the liquid adding box can be slid out or rotated along the slide rail to provide a field of view that is convenient for maintenance and inspection. At the same time, the hose on the top of the liquid adding box can be extended under the limiting action of the clamp frame to maintain the connectivity between the receiving end of the liquid adding box and the connecting pipe, and detachment will not occur, saving the time spent on disassembly.

[0006] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a liquid adding device for sand mixing equipment, including a mounting frame, the mounting frame is installed on the frame of a sand mixing vehicle, two sets of slide rails are fixed on the top of the mounting frame, and a liquid adding box is arranged on the surface of the slide rails, two sets of slide frame seats are rotatably installed on the bottom of the liquid adding box through bearings, and the slide frame seats slide along the surface of the slide rails, a pipeline assembly is provided on the top of the mounting frame between the liquid adding boxes on both sides, and three sets of liquid adding pumps are fixedly installed on the bottom of the pipeline assembly, the liquid adding pump is connected to the delivery pipeline of the pipeline assembly, a receiving end is provided on the top of the liquid adding box, and a hose is fixedly sleeved on the top of the receiving end, a connecting end is fixed on the other end of the hose, and the connecting end is connected to the pipeline assembly.

[0007] Furthermore, a middle plate is fixed at the middle position of the slide rail, and the middle plate is in compression contact with the liquid filling boxes on both sides.

[0008] Furthermore, locking frames are buckled at the openings at both ends of the slide rail, and bolts are inserted at both sides of the locking frames. Screw holes are opened at positions of the slide rail corresponding to the bolts, and the bolts are engaged and inserted into the screw holes.

[0009] Furthermore, a flow meter is provided at the upper end of the pipeline assembly, and a four-way valve is provided at the upper end of the flow meter, and connecting pipes are fixed on the surface of the four-way valve at positions corresponding to the four groups of liquid adding tanks, and the connecting ends are fixedly sleeved on the connecting pipes.

Compared with the prior art, the utility model has four groups of liquid adding boxes that are slidably installed on the slide rail at the top of the mounting frame, and the top is connected to the pipeline assembly through a hose.

In actual use, the liquid adding technology of the sand mixing device is realized through the mutual cooperation of the liquid adding pump 2, the pipeline assembly 3 and the liquid adding box 4. When the pipeline needs to be inspected and repaired, one side of the liquid adding box 4 is slid along the slide rail 11, and the pipeline assembly 3 vertically arranged in the middle position leaks out, which is convenient for technicians to repair and inspect it.

[0024] In this embodiment, an intermediate plate 49 is fixed to the middle position of the slide rail 11, and the intermediate plate 49 is in compression contact with the liquid adding boxes 4 on both sides, locking frames 12 are buckled at the openings at both ends of the slide rail 11, and bolts 13 are inserted on both sides of the locking frame 12, and the slide rail 11 is provided with screw holes 14 at positions corresponding to the bolts 13, and the bolts 13 are engaged and inserted into the screw holes 14, and the liquid adding box 4 is installed on the slide rail 11, and the two ends of the slide rail 11 are buckled through the locking frames 12.

When the liquid adding box 4 moves along the slide rail 11, the hose 43 changes from an S-shaped curve, and the slider 47 slides along the slider 45 and gradually becomes a straight line, so that the change in the distance between the connecting end 410 and the connecting pipe 34 will not affect the connection between the two. When resetting, the S-shaped curve of the hose 43 is restored by the elastic force of the spring 46.
