Description

Technical Field

[0001] This utility model relates to the technical field of sand conveyor equipment, specifically a spiral sand conveyor for fracturing sand mixing trucks. Background Technology

[0002] The fracturing sand mixing truck plays a crucial role in fracturing operations. It is mainly used to mix, stir, and transport the sand and other media required for fracturing operations. The main structure of the sand mixing truck includes a transmission system, a fluid supply system, and a sand conveying system. Through its internal mixing tank and sand conveyor, the sand mixing truck can mix sand and gravel with fracturing fluid in a specific ratio to ensure the uniformity and stability of the mixture, thereby meeting the needs of fracturing operations. The sand conveyor is mainly used to transport manufactured sand of various particle sizes and properties, including coarse sand, fine sand, and wet sand. The use of the sand conveyor improves the working efficiency of the sand mixing truck.

[0003] Application number CN211573499U discloses a spiral sand conveyor for fracturing sand mixing trucks, including a guide tube, a first sleeve, and a second sleeve. Both the first and second sleeves are mounted on the outer side of the guide tube via bearings. An outer ball is welded to the top of the first sleeve, and an inner ball is secured to the inner side of the outer ball. A retaining plate is welded to the top of the inner ball. A motor is bolted to one end of the guide tube, and a base is bolted to the bottom of the motor. A retaining sleeve is provided at the bottom of the second sleeve, and a crossbar is welded to one end of the retaining sleeve. A baffle is welded to the bottom of the second sleeve. A spiral plate is secured to the inner side of the guide tube, and a partition is welded to one side of the spiral plate. This integrated spiral conveyor improves dry-wet separation, allows for free adjustment of the guide tube outlet position, facilitates flexible adjustment, and is more convenient to use. It effectively controls the slurry falling speed and reduces the pressure of the slurry on the spiral plate in the fracturing sand mixing truck, making it suitable for sand conveying in fracturing sand mixing trucks.

[0004] Existing technologies include a guide tube, a spiral plate, and a screw, which together form a dimmable sand conveyor to achieve the function of conveying. The guide tube, in conjunction with components such as a sleeve and an outer ball, works in conjunction with the rotation of the screw and spiral plate to control the speed of mortar falling and complete the material conveying work. However, during the material conveying process, impurities are easily mixed in with different materials, affecting the quality of the mixing. During the feeding process, the position of the feeding component is fixed and cannot be flexibly adjusted, which in turn affects the working efficiency of the sand conveyor. Utility Model Content

The feeding structure 3 includes an adjusting rod 301. A movable plate 302 is sleeved on the external part of the adjusting rod 301. The internal part of the movable plate 302 is connected to the feeding box 305. A flexible hose 303 is provided at the bottom of the feeding box 305.

[0030] An adjustable feed box 305 is provided. By adjusting the adjusting rods 301 on both sides of the feed box 101, the angle of the movable plate 302 is changed. The adjustment is made according to the direction that facilitates feeding, so that the feeding work can be carried out quickly, improving the flexibility of the feed box 305 during use and the efficiency of quickly completing the feeding work.

[0031] The top of the material bin 101 has an opening on one side. Rotary disks 102 are movably installed at both ends inside the material bin 101. The outer surfaces of both sides of the rotating disk 102 are fixedly connected to the two ends of the spiral blades 103. One side of the rotating disk 102 is electrically connected to the connecting seat 201 in the drive assembly 2. The spiral blades 103 work in conjunction with the rotating disk 102 to rotate and push the material for transmission.

[0032] The outer side of the connecting seat 201 is electrically connected to the motor 202. A junction box 203 is fixedly installed on the outer side of the motor 202. Grooves are provided on both sides of the material box 101. The inside of the grooves is movably connected to the bottom of the adjusting rod 301 in the feeding structure 3.

[0033] A filter disc 304 is installed inside the feed box 305 to filter impurities in the material during the feeding process, thereby ensuring the quality of the mixed material. At the same time, the filter disc 304 is easy to disassemble and install, facilitating quick cleaning.

[0034] The adjusting rod 301 extends to both sides of the material box 101. An adjusting screw cap is fixedly installed on the top of the adjusting rod 301. A movable plate 302 is movably sleeved on the outer wall of the adjusting rod 301. The inner side of the movable plate 302 is connected to the outer surface of the feeding box 305. A feeding hole is opened at the center of the bottom surface inside the feeding box 305. The bottom of the feeding hole is fixedly connected to the hose 303. The bottom of the hose 303 is fixedly connected to the inside of the opening.

[0037] The adjusting rod 301 is a cylindrical threaded rod, and the movable plate 302 has a threaded bushing that matches the adjusting rod 301.

[0038] Working principle: During use, fracturing sand is conveyed from the outside to the feed box 305 and falls onto the filter plate 304. The filter holes on the filter plate 304 perform preliminary screening of the sand particles to ensure that the sand particles entering the sand conveying system meet the particle size requirements and prevent impurities from entering. The adjusting rod 301 adopts a threaded structure. By rotating the adjusting screw cap, the height of the movable plate 302 can be adjusted, thereby changing the tilt angle of the feed box 305 to adapt to different working conditions. The sand particles enter the hose 303 through the feed hole. The hose 303 connects to the opening at the top of the feed box 101. The connection ensures that the sand enters the sand conveying system smoothly. The motor 202 receives power through the junction box 203 and drives the connecting seat 201 to drive the rotating disk 102 to rotate. The two ends of the spiral blade 103 are fixed on the rotating disk 102. The rotation of the rotating disk 102 causes the spiral blade 103 to form a continuous spiral propulsion action, pushing the sand particles to move towards the bottom of the material box 101. Under the push of the spiral blade 103, the sand particles move along the inner wall of the material box 101 towards the bottom discharge hole. The sand is transported to the mixing system of the sand mixing truck to participate in the preparation of fracturing fluid.
