Description

A New Structure Diffusion Box

technical field

The utility model relates to a diffusion box with a new structure.

Background technique

As the application of oilfield cementing equipment is becoming more and more extensive, users have higher and higher requirements for cementing operations. However, the existing diffusion box has problems such as easy water leakage at the junction between the diffusion box body and the upper cover, easy backwater at the smoke exhaust elbow, complex manufacturing process of the upper cover, and inconvenient cleaning inside the diffusion box, which requires users to spend a lot of time Proceed to clean the exterior and interior of the diffuser box.

Utility model content

The technical problem to be solved by the utility model is to provide a diffusion box with a new structure to solve the deficiencies of the prior art.

The technical solution of the utility model for solving the above-mentioned technical problems is as follows: a diffusion box with a new structure, which includes a diffusion box body and an upper cover; the upper cover is arranged at the smoke outlet above the diffusion box body, and the diffusion box The body is provided with an elliptical head at the connection with the upper cover; the lower end of the diffuser box is provided with guide vanes; There is a smoke exhaust pipe on the top, the lower end of the smoke exhaust pipe extends into the diffusion box, the upper end of the smoke exhaust pipe extends out of the upper cover, and a smoke exhaust elbow is provided at the smoke exhaust port of the smoke exhaust pipe.

The beneficial effects of the utility model are: the upper part of the diffuser box is optimized from a thin plate to a standard elliptical head, which eliminates dead angles, makes cleaning easier, has a beautiful appearance, and greatly reduces the production cost. The deflector blades make the clear water flow reflect and hit the inner wall of the diffuser box directly, avoiding the direct reflection to the smoke outlet of the upper cover, causing backwater.

detailed description

The principles and features of the present utility model are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the utility model, and are not used to limit the scope of the utility model.

As shown in Figure 1 and Figure 2, a diffusion box with a new structure includes a diffusion box body 11 and an upper cover 7; the upper cover 7 is arranged at the smoke outlet above the diffusion box body 11, and the diffusion box The box body 11 is provided with an elliptical head 9 at the junction with the upper cover 7, and the upper part of the diffuser box body 11 is optimized from a thin plate to a standard elliptical head 9, which eliminates dead angles, makes cleaning easier, and has a beautiful appearance and is extremely Greatly reduce the production cost. The sealing between the diffuser box body 11 and the upper cover 7 is effectively improved, and the problem of water leakage at the connection between the diffuser box body 11 and the upper cover 7 is solved. Preferably: the diffuser box body 11 and the upper cover 7 are tightly connected by a heavy-duty buckle 5 . The outside of the diffuser box body 11 is provided with a slurry inlet pipe 3 communicating with the inside of the diffuser box body 11; the upper cover 7 is provided with a smoke exhaust pipe 10, and the lower end of the smoke exhaust pipe 10 extends into the diffuser box body 11, The upper end of the smoke exhaust pipe 10 protrudes from the upper cover 7, and the smoke outlet of the smoke exhaust pipe 10 is provided with a smoke exhaust elbow 6, which increases the protruding height of the smoke exhaust pipe 10 on the upper part of the upper cover 7, which is beneficial to the accumulation of fly ash , and discharged from the exhaust elbow 6. Preferably: the smoke exhaust elbow 6 is made of rubber material, which is convenient for disassembly and assembly.

Preferably: an O-shaped sealing ring 8 is also included, and the O-shaped sealing ring 8 is arranged at the joint between the oval head 9 and the upper cover 7 .

Preferably: the lower end of the diffusion box body 11 is provided with a guide vane 1, and the guide vane 1 is a folded plate guide vane, which adopts the structural form of a folded plate guide vane, so that the clear water flow is reflected and directly hits the diffuser box On the inner wall of the body 11, it avoids being directly reflected to the smoke outlet of the loam cake 7, causing backwater.

This example also includes a mounting plate 2; the mounting plate 2 is ring-shaped, and the mounting plate 2 is sleeved in the middle of the diffuser box body 11 .

Preferably: the exterior of the upper cover 7 is provided with a handle 4 .

When in use, the utility model is fixed to the mounting plate 2 and the mud mixing tank by threaded connection. The sprayed water, ash and secondary circulating mud enter the diffusion box body 11 tangentially from the slurry inlet pipe 3, vortex descends, and flow out through the round hole at the bottom of the diffusion box body 11 into the mud mixing tank. When the cement slurry is mixed in the diffuser box 11 , the generated fly ash enters the smoke exhaust pipe 10 and is discharged through the smoke exhaust elbow 6 .

The above are only preferred embodiments of the utility model, and are not intended to limit the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model shall be included in the utility model. within the scope of protection.
