Description

Technical Field

[0002] Large fracturing sand tanks are a key equipment used in oilfield fracturing operations. Their main function is to store and supply fracturing sand. The measurement of large fracturing sand tanks mainly involves measuring the volume or mass of fracturing sand in the tanks. This is usually to ensure that the amount of sand used in the fracturing process is accurate to achieve the desired fracturing effect. The buffer tank is an intermediate storage device located between the fracturing sand tank and the fracturing equipment. Its main function is to balance the sand supply speed and ensure a continuous and stable supply of sand during the fracturing process.

[0003] During the metering process of a large-scale fracturing sand tank, when assistance is needed through a buffer tank, the fracturing sand or other related liquids are first introduced into the buffer tank body through the feed pipe, and then a certain amount of fracturing sand and related liquids are stored in the storage area inside the buffer tank body, and then the outflow of the fracturing sand is controlled by opening and closing the discharge pipe, and at this time, the gas inside the buffer tank body is discharged through the exhaust pipe, thereby assisting the metering and supply of the fracturing sand tank to ensure a balanced and stable sand supply during the fracturing process, and then ensure that the sand can flow into the fracturing equipment evenly and continuously; but during the use of the buffer tank, in order to avoid material overflow, it is often necessary to adjust the feed amount and feed speed of the buffer tank according to the specific conditions on site, and a pressure regulating valve is usually used to adjust the feed of the buffer tank, but this adjustment method is limited by temperature and air pressure, and may cause the system pressure to be too high or too low, especially in high pressure or high temperature environments, the safety hazards are more prominent, and then cause safety accidents.

[0006] Compared with the prior art, the beneficial effects of the utility model are as follows: when the easy-to-adjust buffer tank for metering large-scale fracturing sand tanks is in use, the feed amount of the feed pipe is adjusted by the adjusting mechanism to prevent excessive material inside the buffer tank body, and the protective mesh plate is cleaned at the same time to prevent the protective mesh plate from being blocked and affecting the filtering effect, thereby facilitating the adjustment of the feed amount and preventing the protective mesh plate from being blocked.

[0007] 1. During the metering process of large-scale fracturing sand tanks, when a buffer tank is needed for assistance, the dual-axis motor is first started to drive the large bevel gear to rotate slowly through the small bevel gear, thereby causing the baffle plate to rotate, resulting in changes in the opening size of the discharge pipe, and then automatically adjusting the feeding speed and feeding amount of the feeding pipe to prevent excessive material inside the buffer tank body.

Therefore, when the buffer tank for metering large-scale fracturing sand tanks is used, it is convenient to adjust the feeding amount and prevent the protective mesh plate from being blocked;

[0008] 2. During the metering process of large-scale fracturing sand tanks, when a buffer tank is needed for assistance, when the material enters the buffer tank body through the feed pipe, it first collides with the protective mesh plate, and then the entering material is buffered by the protective mesh plate to prevent the material from falling and directly impacting the bottom of the buffer tank body and causing damage to it.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 7 The utility model provides a technical solution: a buffer tank that is easy to adjust for metering a large-scale fracturing sand tank, comprising a buffer tank body 1, an adjusting mechanism 6 and an auxiliary mechanism 7, a feed pipe 2 is docked on one side of the top of the buffer tank body 1, and a discharge pipe 3 is docked on the middle of the bottom end of the buffer tank body 1, an exhaust pipe 4 is installed on the side of the top of the buffer tank body 1 away from the feed pipe 2, and a supporting foot 5 is sleeved on the bottom end of the outer wall of the buffer tank body 1, the adjusting mechanism 6 comprises a double-axis motor 601, a small bevel gear 602, a large bevel gear 603, a rotating column 604, a baffle plate 605, a fixed seat 606, a rotating plate 607, a rubber cleaning plate 608 and a filter screen plate 609, and a double-axis motor 6 is installed on one side of the top of the buffer tank body 1 close to the exhaust pipe 4 01, and a small bevel gear 602 is connected to the output end of the bottom end of the dual-axis motor 601, and a filter screen plate 609 is connected to the top end of the exhaust pipe 4; the outer wall of the small bevel gear 602 is meshed with a large bevel gear 603, and a rotating column 604 is welded inside the large bevel gear 603; fixed seats 606 are sleeved on both sides of the outer wall of the rotating column 604, and a blocking plate 605 is welded on the side of the outer wall of the rotating column 604 close to the feed pipe 2; a rotating plate 607 is connected to the output end of the top end of the dual-axis motor 601, and a rubber cleaning plate 608 is connected to the outer wall of the rotating plate 607; the rubber cleaning plate 608 is fixedly connected to the rotating plate 607, the outer wall of the rubber cleaning plate 608 is in contact with the filter screen plate 609, and the top of the fixed seat 606 is welded to the buffer tank body 1.

[0021] During specific implementation, when a buffer tank is needed to assist in metering a large-scale fracturing sand tank, in order to avoid material overflow, the feeding speed and feeding amount of the feeding pipe 2 need to be adjusted according to the on-site conditions. First, start the dual-axis motor 601. Since the bottom output end of the dual-axis motor 601 is connected to the small bevel gear 602, the dual-axis motor 601 starts to drive the small bevel gear 602 to rotate. Since the small bevel gear 602 is meshed with the large bevel gear 603, the small bevel gear 602 rotates quickly to drive the large bevel gear 603 to rotate slowly. Then, the large bevel gear 603 rotates to drive the rotating column 604 to rotate along the fixing seat 606.

[0022] And because the rotating column 604 and the blocking plate 605 are welded, the rotating column 604 rotates and drives the blocking plate 605 to rotate together, and then with the rotation of the blocking plate 605, the size of the opening of the discharge pipe 3 extending into the buffer tank body 1 changes, and then the feeding speed and feeding amount of the feeding pipe 2 are automatically adjusted to prevent excessive material in the buffer tank body 1, and no longer adjusted by the regulating valve, thereby preventing the regulating valve from causing the system pressure to be too high or too low, and ultimately increasing the potential safety hazards and causing safety accidents;

[0023] Because the filter screen plate 609 is connected to the top of the exhaust pipe 4, when the exhaust pipe 4 is exhausted, the gas is filtered through the filter screen plate 609, and because the top output end of the dual-axis motor 601 is connected to the rotating plate 607, the dual-axis motor 601 also drives the rotating plate 607 to rotate when it is started, and then the rotation of the rotating plate 607 drives the rubber cleaning plate 608 to rotate together, and then facing the rotation of the rubber cleaning plate 608, the rubber cleaning plate 608 and the protective screen plate 705 are constantly rubbed, and then the protective screen plate 705 is cleaned to prevent the protective screen plate 705 from being blocked and affecting the filtering effect, and then when adjusting the feeding speed of the feed pipe 2, the protective screen plate 705 is also cleaned, so that when the buffer tank for metering of large-scale fracturing sand tanks is used, it is convenient to adjust the feed amount and prevent the protective screen plate 705 from being blocked.

[0024] See also Figure 1-Figure 4 , Figure 8 and Fig. 9 It can be seen that the auxiliary mechanism 7 includes a support platform 701, a support rod 702, a support seat 703, a limit seat 704, a protective mesh plate 705 and a spring 706. The support platform 701 is welded to the top of the outer wall of the support foot 5; the support platform 701 is connected to the top of the support rod 702, and the support seat 703 is connected to the top of the support rod 702; a limit seat 704 is installed in the middle of the inner wall of the buffer tank body 1, and the protective mesh plate 705 is slidably connected inside the limit seat 704; the spring 706 is connected to the bottom end of the outer wall of the protective mesh plate 705, and the limit seat 704, the protective mesh plate 705 and the spring 706 form an elastic telescopic mechanism; the spring 706 is connected to the limit seat 704, the bottom end of the support rod 702 is welded to the support platform 701, and a triangular stabilization mechanism is formed between the support platform 701, the support rod 702 and the support seat 703.

[0025] During specific implementation, during the metering process of a large-scale fracturing sand tank, when a buffer tank is needed for assistance, in order to prevent the material from directly impacting the bottom of the buffer tank body 1, thereby causing damage to the bottom of the buffer tank body 1, when it needs to be protected, a protective mesh plate 705 is installed in the middle of the buffer tank body 1 through a limit seat 704. When the material enters the buffer tank body 1 through the feed pipe 2, it first collides with the protective mesh plate 705, and then the protective mesh plate 705 moves downward due to the collision to squeeze the spring 706, causing the spring 706 to deform, and then the protective mesh plate 705 is used to buffer the incoming material to prevent the material from falling and directly impacting the bottom of the buffer tank body 1, causing damage to the bottom of the buffer tank body 1, and then the elastic force generated by the reset of the spring 706 causes the protective mesh plate 705 to collide with the limit seat 704, thereby preventing the protective mesh plate 705 from being blocked;

[0026] Because the support platform 701 is welded to the support rod 702, the support seat 703 fits with the buffer tank body 1. At this time, a triangular stabilization mechanism is formed between the support platform 701, the support rod 702, and the support seat 703, thereby providing auxiliary support for the buffer tank body 1, thereby improving the stability of the buffer tank body 1, thereby facilitating protection and auxiliary support when the buffer tank is used for metering of large fracturing sand tanks.

[0027] To sum up, when this large-scale fracturing sand tank metering and easy-to-adjust buffer tank is used, the fracturing sand or other related liquids are first introduced into the buffer tank body 1 through the feed pipe 2, and then a certain amount of fracturing sand and related liquids are stored in the storage area inside the buffer tank body 1. After that, the outflow of the fracturing sand is controlled by opening and closing the discharge pipe 3, and at this time, the gas inside the buffer tank body 1 is discharged through the exhaust pipe 4, thereby assisting the metering and supply of the fracturing sand tank to ensure a balanced and stable supply of sand during the fracturing process, and then ensuring that the sand can flow into the fracturing equipment evenly and continuously. This is the prior art and will not be elaborated on here. The feed amount of the feed pipe 2 is adjusted by the adjustment mechanism 6 to prevent excessive material inside the buffer tank body 1, and at the same time, the protective mesh plate 705 is cleaned to prevent the protective mesh plate 705 from being blocked and affecting the filtering effect. The incoming material is buffered by the auxiliary mechanism 7 to prevent the material from falling and directly impacting the bottom of the buffer tank body 1 and causing damage to it, and the buffer tank body 1 is auxiliary supported. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
