Description

Technical Field

[0001] The utility model relates to the technical field of feeding, in particular to a fracturing powder feeding device. Background Art

[0002] In the field of oil extraction, the role of the continuous mixing vehicle is to continuously mix fracturing powder, clean water and additives, and deliver the prepared fracturing fluid to the fracturing vehicle for fracturing operations. The feeding methods of fracturing powder are as follows: one is to use a crane to lift the fracturing powder bag and move it to the feeding port of the continuous mixing vehicle. The staff uses a utility knife to cut the fracturing powder bag to release the fracturing powder into the feeding port. This feeding method relies on manual operation of the crane and utility knife, and has low production efficiency; the other is to store the fracturing powder in a large storage tank in advance, and set up a conveying device between the storage tank outlet and the feeding port when feeding, so as to automatically feed the fracturing powder into the feeding port. This feeding method also has problems. For example, the storage tank outlet needs to be aligned with the conveying device to be used normally, but the storage tank is large and inconvenient to move; it is inconvenient for the staff to check the remaining amount of fracturing powder in the storage tank, and it is impossible to judge whether the fracturing powder is used up.

[0018] like Figure 1 As shown, this embodiment provides a fracturing powder feeding device, including a storage tank 1, a conveying mechanism 2, a mobile frame 3, a wireless distance alarm, and a measuring plate height control mechanism 4.

[0019] Specifically, four universal wheels are provided at the bottom of the mobile frame 3, each universal wheel has a locking function and is used to fix the mobile frame 3. The storage tank 1 is installed on the mobile frame 3. A feed port 11 is provided at the top of the storage tank 1 for loading the fracturing powder into the storage tank 1. A discharge port 12 is provided at the bottom of the storage tank 1. A valve is provided at the discharge port 12 for controlling the opening and closing of the discharge port 12. The conveying mechanism 2 is used to convey the fracturing powder released from the discharge port 12 to the feeding port 61 of the mixing vehicle.

[0020] Specifically, Figure 2 , Figure 4 As shown, the measuring plate height control mechanism 4 includes a measuring plate 41 and a cable retracting mechanism. The measuring plate 41 is arranged in the storage tank 1 and located on the top of the fracturing powder. The cable retracting mechanism is arranged on the top of the storage tank 1. The rope 42 passes through the storage tank 1 and is connected to the measuring plate 41.

[0021] The specific implementation method of the cable retracting and releasing mechanism is as follows: Figure 2 , Figure 3 As shown, it includes a motor 43, a clamping assembly 44 and a hinge wheel 45. The motor 43 is arranged on a base, and the output shaft of the motor 43 is connected to the clamping assembly 44. Both ends of the hinge wheel 45 are respectively rotatably matched with the support plate 451. One end of the hinge wheel 45 passes through the support plate 451 and is connected to a rotating rod 452. The clamping assembly 44 is used to clamp the rotating rod 452. The clamping assembly 44 is a conventional assembly and its structure is not described in detail. The hinge wheel 45 is used to wind the rope 42.

[0022] The measuring plate height control mechanism 4 can be used in two ways:

[0023] The first method: under the action of the motor 43, the reel 45 first completely releases the rope 42, and the clamping assembly 44 always clamps the rotating rod 452. When the remaining amount of fracturing powder in the storage tank 1 gradually decreases, the measuring plate 41 moves downward under the action of gravity, and the measuring plate 41 is always located on the top of the fracturing powder. During the downward movement of the measuring plate 41, the rope 42 unfolds accordingly, and the reel 45 does not need to rotate; when the fracturing powder is used up, the rope 42 is wound around the reel 45 under the action of the motor 43, and the measuring plate 41 is reset upward.

[0024] The second method: the clamping assembly 44 releases the rotating rod 452. When the remaining amount of fracturing powder in the storage tank 1 gradually decreases, the measuring plate 41 moves downward under the action of gravity, and the measuring plate 41 is always located on the top of the fracturing powder. During the downward movement of the measuring plate 41, the rope 42 is driven, and the rope 42 in turn drives the hinge wheel 45 to rotate; when the fracturing powder is used up, the clamping assembly 44 clamps the rotating rod 452, and under the action of the motor 43, the rope 42 is rewound around the hinge wheel 45, and the measuring plate 41 is reset upward.

[0025] Specifically, the wireless distance alarm includes a mother machine 51 and a child machine 52. The wireless distance alarm belongs to the existing technology and can be purchased in the market or on an online shopping website. It is often used between parents and children. For example, when playing outside or shopping, the father carries the mother machine 51 and the child carries the child machine 52. When the distance between the two exceeds a certain range, the wireless distance alarm will sound an alarm. This wireless distance alarm can also set the alarm range by itself, which is very convenient to use. Specifically in this solution, the mother machine 51 is set on the top of the storage tank 1, and the child machine 52 is set on the measuring plate 41. When the child machine 52 gradually descends with the measuring plate 41 and approaches the discharge port 12, an alarm is sounded to remind the staff that the fracturing powder in the storage tank 1 is about to run out.

[0026] More specifically, Figure 4 As shown, in order to improve the stability of the measuring plate 41 during the upward and downward movement, a balancing block 411 is further provided on the measuring plate 41. The balancing block 411 is equal in weight to the slave 52 and is symmetrically positioned.

[0027] In the prior art, the volume of the storage tank 1 is generally fixed. In order to solve this problem and to be able to change the volume of the storage tank 1 according to actual needs, the present embodiment takes the following measures: the storage tank 1 includes a bottom tank 111 and a top tank 112. The top tank 112 is sleeved on the outer periphery of the bottom tank 111. The outer wall of the bottom tank 111 is close to the inner wall of the top tank 112. The discharge port 12 is arranged at the bottom of the bottom tank 111. The feed port 11, the measuring plate height control mechanism 4 and the mother machine 51 are all arranged on the top of the top tank 112. A height adjustment mechanism 6 is provided on the movable frame 3. The height adjustment mechanism 6 is connected to the top tank 112 for adjusting the height of the top tank 112.

[0028] In the prior art, there are many ways to implement the height adjustment mechanism 6, such as using multiple lifting rods driven by air cylinders, oil cylinders, or hydraulics. When the volume of the storage tank 1 needs to be adjusted, the height adjustment mechanism 6 can move the volume of the top tank 112 up or down. In addition, please note that after adjusting the volume of the storage tank 1, the alarm range of the wireless distance alarm also needs to be adjusted in time.

[0029] The above embodiments are only used to illustrate the technical ideas and features of the utility model, and are not intended to be the only or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
