Description

Technical Field

[0001] This utility model relates to the field of mixing pump technology, specifically to an oilfield mixing pump. Background Technology

[0002] Oilfield mixing pumps are key equipment in oilfield operations, used to mix drilling fluids, additives, and other materials. They utilize centrifugal force generated by impeller rotation to ensure thorough mixing and transport of the media. Characterized by high flow rates and stable pressure, they improve drilling efficiency, ensure drilling fluid performance, and play a vital role in oilfield exploration and development.

[0003] Chinese utility model patent CN29952618U discloses a homogenizing pump, which includes "a transmission end and a hydraulic end connected together, the transmission end including a base, a rotating shaft driven by a power mechanism being disposed inside the base, the hydraulic end including a pump body, a working chamber being formed inside the pump body, a stator being fixed inside the pump body, the stator cooperating with a rotor, and one end of the rotating shaft being connected to the rotor"; however, due to its large size design, this homogenizing pump not only occupies a lot of working space during actual operation, but also makes the position of the material addition port relatively fixed and the operating space narrow. Therefore, it is difficult for users to accurately control the addition amount, reducing production efficiency and increasing the complexity and error risk of operation. Utility Model Content

[0014] The outer surface of the housing is further configured such that two dustproof nets are fixedly installed on it by screws and nuts.

[0015] By adopting the above technical solution, the outer casing and dustproof net will protect the device from pump shaft blockage caused by splashing during material feeding during operation.

[0016] To achieve mixing of raw materials:

[0017] The motor and impeller are further configured to form a rotating structure via a coupling.

[0018] By adopting the above technical solution, the motor will drive the pump shaft to rotate, and the impeller installed at the bottom of the pump shaft will be evenly mixed and stirred.

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0029] Please see Figures 1 to 4 An oilfield mixing pump includes a drive assembly 1, a stirring assembly 2 fixedly mounted on the top of the drive assembly 1, and a pump body 3 fixedly mounted on the bottom of the stirring assembly 2.

[0030] The drive assembly 1 includes a motor 11, a rotating shaft 12 is rotatably mounted inside the motor 11, a coupling 13 is fixedly mounted at the bottom of the rotating shaft 12, a first bracket 14 is fixedly mounted on the outer surface of the motor 11, four first threaded pins 15 are threaded inside the first bracket 14, and a housing 16 is fixedly mounted at the bottom of the first bracket 14, and the first bracket 14 and the housing 16 form a fixed connection structure through the first threaded pins 15.

[0031] The stirring assembly 2 includes a pump shaft 21 fixedly installed at the bottom of the coupling 13, a support seat 22 slidably installed on the outer surface of the pump shaft 21, an upper support bearing 23 slidably installed on the top of the support seat 22, a lower support bearing 24 slidably installed on the bottom of the support seat 22, a second bracket 25 fixedly installed on the top of the support seat 22, and an impeller 26 slidably installed on the bottom of the pump shaft 21.

[0032] The pump body 3 includes a connecting base 31 fixedly installed on the outer surface of the second bracket 25. A frame 32 is fixedly installed at the bottom of the connecting base 31, and the connecting base 31 and the frame 32 are fixedly connected by screws and nuts. A feed funnel 33 is fixedly installed on the top of the connecting base 31 by welding, and a discharge port 34 is fixedly installed on the outer surface of the frame 32.

[0033] In this embodiment, as Figure 1 As shown, the motor 11 and the coupling 13 form a rotating structure through the rotating shaft 12.

[0034] In this embodiment, as Figure 2 As shown, two dustproof nets 17 are fixedly installed on the outer surface of the housing 16 by screws and nuts.

[0035] In this embodiment, as Figure 3 As shown, the motor 11 and the impeller 26 form a rotating structure through the coupling 13.

[0036] In this embodiment, as Figure 4 As shown, a support base 35 is fixedly installed at the bottom of the frame 32 by welding.

[0037] The working process of this oilfield mixing pump is as follows:

[0038] First, the user needs to place the device in a suitable position, then pour the raw materials into the feed funnel 33. The raw materials enter the frame 32 through the feed funnel 33. After preparation is complete, start the mixing pump.

[0039] Then, the motor 11 is started by an external electrical control device. The motor 11 will drive the rotating shaft 12 to rotate. The coupling 13, which is fixedly installed at the bottom of the rotating shaft 12, will connect the motor 11 and the pump shaft 21 to rotate together. The first bracket 14 and the outer shell 16, which are fixedly installed on the outer surface of the motor 11, will be fixedly connected together by the first threaded nail 15. At the same time, the two dustproof nets 17, which are fixedly installed on the outer surface of the outer shell 16 by screws, can protect the device from material splashing when the material enters the device during operation. This will prevent the material from splashing into the device and causing the mixing pump to become blocked during operation over time.

[0040] Meanwhile, the coupling 13 fixedly installed at the bottom of the rotating shaft 12 will also drive the pump shaft 21 fixedly installed at the bottom of the coupling 13 to rotate together, and the impeller 26 at the bottom of the pump shaft 21 will also rotate together with the pump shaft 21, thereby realizing the mixing of the raw materials inside the mixing frame 32. After the raw materials are mixed, they will flow out through the discharge port 34.
