Description

Technical Field

[0001] The utility model belongs to the technical field of oil well cementing, and particularly relates to a water distribution skid for well cementing operations. Background Art

[0002] Well cementing is an important operation in the drilling process. In general, there are at least two well cementing operations (production wells) in the drilling operation, and up to 4 - 5 well cementing operations (deep exploration wells). The top well cementing is the surface casing cementing, which plays the role of "mud passage, oil and gas portal". Before the next drilling, a blowout preventer should be installed on the surface casing to prevent blowout, and a mud duct should be installed above the blowout preventer, which is the passage for the drilling fluid to return to the mud pit. During the drilling process, it is often necessary to set technical casing for well cementing, which plays the role of "consolidating the rear and safely exploring the way". Just like the tunnels on the road and the roadways in coal mines, well collapses, high pressures, and unstable formations may also be encountered during the drilling process. At the same time, it is also to have a retreat in case of danger during the forward "exploration" and play the role of "rescue".

[0003] However, for the existing water distribution skids used at the well cementing operation site, when stirring materials and adding admixtures, most of them use a single driving mechanism for one-way stirring, resulting in poor stirring effect, insufficient mixing of materials and added admixtures, and thus affecting the overall concrete quality.

[0004] Therefore, a water distribution skid for well cementing operations is needed to solve the problem of insufficient stirring of materials and mixed additives in the existing technology. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a water distribution skid for well cementing operations to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A water distribution skid for well cementing operations, including a mixing tank, the middle of the top of the mixing tank is fixedly provided with a feed inlet, the bottom of the mixing tank is fixedly provided with a filter box, the bottom of the filter box is fixedly provided with a discharge bin, a discharge port is arranged at the bottom end of one side of the discharge bin, a driving motor is fixedly arranged on one side of the mixing tank, a protective member is fixedly arranged at the center of one side of the mixing tank, and a two-way rotation mechanism is arranged on the inner wall of the protective member;

[0007] A screw conveyor is rotatably installed at the center of the discharge bin, and a linkage mechanism is fixedly arranged at one end of the screw conveyor.

[0008] It should be noted in the solution that the two-way rotation mechanism includes a first bevel gear, the center of the first bevel gear is fixedly arranged at the driving end of the driving motor, and both sides of the outer wall of the first bevel gear are meshed with a second bevel gear and a third bevel gear respectively.

[0009] Further, it is worth noting that a connecting rod is fixed at the center of one end of the second bevel gear, a first stirring member is fixed on the outer wall of the connecting rod, a mounting pipe is fixed at the center of the third bevel gear, a second stirring member is fixed on the outer wall of the mounting pipe, and the connecting rod penetrates through the third bevel gear and the inner wall of the mounting pipe.

[0010] Furthermore, it should be noted that the linkage mechanism includes a driving sprocket, which is fixedly installed at one end of the connecting rod;

[0011] The linkage mechanism further includes a driven sprocket, one end of which is fixedly installed at one end of the auger, and a chain is meshed and connected between the driving sprocket and the driven sprocket.

[0012] As a preferred embodiment, the mixing tank is communicated with the filter box and the discharge bin, a limiting groove is formed in the inner wall of the filter box, and a filter screen is slidably installed on the inner wall of the limiting groove.

[0013] As a preferred embodiment, brackets are fixed at both ends of the outer wall of the mixing tank.

[0014] Compared with the prior art, a cementing operation water distribution skid provided by the present utility model has at least the following beneficial effects:

[0015] (1) Through the mutual cooperation of the bidirectional rotation mechanism, the first bevel gear, the second bevel gear, the third bevel gear, the connecting rod, the first stirring member, the mounting pipe, and the second stirring member, the mixed materials can be stirred bidirectionally, thereby improving the stirring effect of the materials.

[0016] (2) Through the mutual cooperation of the linkage mechanism, the driving sprocket, the driven sprocket, and the chain, the stirred materials can be conveyed and discharged, and only a single driving mechanism is required, thereby reducing costs, and the sundries inside the mixture can also be filtered through the filter screen to avoid blocking the pipeline subsequently.

[0022] The following further describes the present utility model in conjunction with embodiments.

[0023] Please refer to Figures 1-4 , the present utility model provides a water distribution skid for cementing operations, including a mixing tank 1, a feed inlet 2 is fixedly arranged in the middle of the top end of the mixing tank 1, a filter box 3 is fixedly arranged at the bottom end of the mixing tank 1, a discharge bin 4 is fixedly arranged at the bottom of the filter box 3, a discharge outlet 5 is arranged at the bottom end of one side of the discharge bin 4, a drive motor 6 is fixedly arranged on one side of the mixing tank 1, a protective part 7 is fixedly arranged at the center of one side of the mixing tank 1, and a bidirectional rotation mechanism 8 is arranged on the inner wall of the protective part 7;

[0024] An auger 13 is rotatably installed at the center of the discharge bin 4, and a linkage mechanism 14 is fixedly arranged at one end of the auger 13.

[0025] The bidirectional rotation mechanism 8 can mainly drive the connecting rod 9 and the mounting pipe 11 to rotate bidirectionally, so as to drive the first mixing part 10 and the second mixing part 12 to rotate bidirectionally, thereby better mixing and stirring the materials.

[0026] Further as Figure 1 , Figure 3 shown, specifically, the bidirectional rotation mechanism 8 includes a first bevel gear 81, the center of the first bevel gear 81 is fixedly arranged at the driving end of the drive motor 6, and both sides of the outer wall of the first bevel gear 81 are meshed and connected with a second bevel gear 82 and a third bevel gear 83.

[0027] The first bevel gear 81 can mainly drive the second bevel gear 82 and the third bevel gear 83 to rotate bidirectionally, thereby improving the stirring effect of the materials.

[0029] The connecting rod 9 passes through the third bevel gear 83 and the inner wall of the mounting tube 11 , thereby preventing interference during rotation and thus avoiding poor rotation effect.

[0030] This scheme has the following working process: first, pour the material from the feed port 2 into the inner wall of the mixing tank 1, and then start the driving motor 6, thereby driving the first bevel gear 81 to rotate, thereby driving the second bevel gear 82 and the third bevel gear 83 to rotate, and the second bevel gear 82 can be used to drive the connecting rod 9 to rotate, and further drive the first stirring member 10 to rotate, and then drive the mounting tube 11 to rotate through the third bevel gear 83, thereby driving the second stirring member 12 to rotate, and then bidirectional rotation can be achieved, thereby improving the rotation effect of material mixing, and at the same time, the connecting rod 9 is rotated to drive the driving sprocket 141 to rotate, and then the chain 143 can be used to drive the driven sprocket 142 to rotate, so that the stirred material can be transported.

[0031] According to the above working process, it can be known that the filter screen 16 can mainly filter the impurities inside the material, and then by pulling the filter screen 16, the impurities on the surface of the filter screen 16 can be removed.

Then, through the connecting rod 9, it can drive the driving sprocket 141 to rotate, and further drive the driven sprocket 142 to rotate through the chain 143, thereby driving the auger 13 to rotate and realizing the conveying and discharging of the materials.
