Technical Field

[0001] The utility model relates to the technical field of measuring instruments, and more specifically, to a density instrument for volume testing of petroleum fracturing proppant. Background Art

[0002] Oil fracturing proppant (ceramsite sand) is a ceramic particle product with high fracturing strength. After production, the density of oil fracturing proppant needs to be tested, so a volume test density meter is needed;

[0003] For example, the existing patent: CN208254995U discloses a petroleum fracturing proppant volume test density meter. This prior art can reduce the cleaning frequency and facilitate cleaning through the structural design of the base and the drawer slot, without moving the entire instrument, thereby ensuring the consistency of each measurement condition;

[0004] However, the inventors have experimentally discovered that the prior art has the following problems: when measuring the petroleum fracturing proppant, the prior patent needs to first pour the petroleum fracturing proppant into a funnel, and then open the valve at the bottom of the funnel, so that the petroleum fracturing proppant in the funnel falls into the measuring cylinder, thereby detecting the quality of the petroleum fracturing proppant; however, when measuring the petroleum fracturing proppant, it is necessary to accurately control the amount of the petroleum fracturing proppant falling into the measuring cylinder, so as to ensure the accuracy of the volume test of the petroleum fracturing proppant; however, the valve at the bottom of the prior funnel makes it difficult to control the amount of the petroleum fracturing proppant falling, so in order to ensure the test accuracy, it is necessary to repeatedly adjust the volume of the petroleum fracturing proppant in the measuring cylinder, thereby reducing the measurement efficiency of the petroleum fracturing proppant; in response to the above problems, the inventors have designed a new petroleum fracturing proppant volume test density meter.

DETAILED DESCRIPTION

[0019] See also Figure 1-3 , the utility model provides the following technical solutions:

[0020] Specifically, it refers to a petroleum fracturing proppant volume test density meter, comprising a base 1, two pillars 2 are fixedly connected to the base 1, the upper ends of the two pillars 2 are fixedly connected to a top plate 3, a funnel 5 is fixedly installed on the top plate 3, the bottom of the funnel 5 penetrates through the lower surface of the top plate 3, a measuring cylinder 4 is placed on the base 1, and the measuring cylinder 4 is located directly below the funnel 5. At the same time, a weighing sensor is provided on the base 1, and the measuring cylinder 4 is arranged on the weighing sensor. Therefore, when in use, by pouring the petroleum fracturing proppant into the funnel 5, the petroleum fracturing proppant falls into the measuring cylinder 4 through the funnel 5. When the petroleum fracturing proppant in the measuring cylinder 4 reaches a specified position, the weighing sensor can detect the weight of the petroleum fracturing proppant in the measuring cylinder 4, thereby measuring the density of the petroleum fracturing proppant;

[0021] Specifically, a conveying cylinder 6 is fixedly connected to the bottom of the funnel 5, and the conveying cylinder 6 is communicated with the bottom of the funnel 5. A spiral rod 7 is rotatably connected between the inner walls on both sides of the conveying cylinder 6. The outer surface of the spiral blade of the spiral rod 7 contacts the inner wall of the conveying cylinder 6. A discharge pipe 9 connected to the inside of the conveying cylinder 6 is fixedly connected to the lower surface of the conveying cylinder 6. The discharge pipe 9 is arranged on the side of the conveying cylinder 6 away from the funnel 5. The discharge pipe 9 is located directly above the measuring cylinder 4. A rotating handle 8 is arranged on the surface of the side of the conveying cylinder 6 away from the funnel 5. One end of the spiral rod 7 rotates through the outer surface of the conveying cylinder 6 and is fixedly connected to the rotating handle 8.

[0022] When the petroleum fracturing proppant needs to be poured into the measuring cylinder 4 for measurement, the rotating handle 8 is rotated, which can synchronously drive the spiral rod 7 to rotate, so that the petroleum fracturing proppant dropped into the conveying cylinder 6 can be transported to the discharge pipe 9, and finally dropped into the measuring cylinder 4 through the discharge pipe 9. The above-mentioned spiral filling method can make the petroleum fracturing proppant dropped into the measuring cylinder 4 more accurate. When testing the petroleum fracturing proppant, there is no need to take the petroleum fracturing proppant in the measuring cylinder 4 back and forth, which further improves the use efficiency of the test density meter;

[0023] Specifically, a support seat 10 is provided inside the bottom of the funnel 5, a plurality of support plates 11 are fixedly connected between the outer surface of the support seat 10 and the inner wall of the funnel 5, a rotating shaft 12 is rotatably connected to the support seat 10, and a plurality of rotating rods 13 are fixedly connected to the outer surface of the rotating shaft 12;

[0024] When the oil fracturing proppant in the funnel 5 falls into the conveying tube 6, the rotating shaft 12 is controlled to rotate, and the rotating rod 13 can destroy the oil fracturing proppant at the bottom of the funnel 5, thereby avoiding the oil fracturing proppant from being blocked at the bottom of the funnel 5 as much as possible, further ensuring the use effect of the volume test density meter;

[0025] Specifically, the interior of the support seat 10 is hollow, the lower end of the rotating shaft 12 rotates and penetrates into the support seat 10, the lower end of the rotating shaft 12 is fixedly connected to the bevel gear 14, the outer surface of the support seat 10 is provided with a movable shaft 15, one end of the movable shaft 15 rotates and penetrates into the support seat 10, and the end of the movable shaft 15 located in the support seat 10 is also fixedly connected to the bevel gear 14, and the two bevel gears 14 are meshed and connected;

[0026] Specifically, the other end of the movable shaft 15 rotates and passes through the outer surface of the funnel 5, and the end of the movable shaft 15 located outside the funnel 5 is fixedly connected to a pulley 16, and the end of the spiral rod 7 away from the rotating handle 8 is also fixedly connected to the movable shaft 15, and the other end of the movable shaft 15 rotates and passes through the outer surface of the conveying cylinder 6, and the end of the movable shaft 15 located outside the conveying cylinder 6 is also fixedly connected to the pulley 16, and a transmission belt 17 is connected between the two pulleys 16;

[0027] Therefore, when the screw rod 7 rotates, the two pulleys 16 can be driven to rotate synchronously, so that the rotating shaft 12 rotates synchronously under the meshing transmission of the two bevel gears 14, thereby achieving the purpose of controlling the rotation of the rotating rod 13.

[0028] The working principle of the petroleum fracturing proppant volume test density meter provided by the utility model is as follows: when the petroleum fracturing proppant needs to be poured into the measuring cylinder 4 for measurement, the rotating handle 8 is rotated, which can simultaneously drive the spiral rod 7 to rotate, so that the petroleum fracturing proppant dropped into the conveying cylinder 6 can be conveyed to the discharge pipe 9, and finally dropped into the measuring cylinder 4 through the discharge pipe 9;

[0029] At the same time, when the spiral rod 7 rotates, the two pulleys 16 can be driven to rotate synchronously, so that the rotating shaft 12 rotates synchronously under the meshing transmission of the two bevel gears 14, thereby achieving the purpose of controlling the rotation of the rotating rod 13.
