Abstract
Description
Technical Field
[0001] The utility model belongs to the field of scale inhibitor equipment, in particular to an alloy scale inhibitor for pipelines used in cement production. Background Art
[0002] A pipeline scale inhibitor is a device used to prevent scaling and clogging inside a pipeline. In the cement production process, the purpose of using a scale inhibitor is to prevent scaling inside the pipeline. When scaling occurs inside the pipeline, scaling substances will adhere to the pipeline wall, resulting in a reduction in the effective flow cross-sectional area of the pipeline, thereby reducing the ability of the fluid to pass through the pipeline, which will cause the pipeline flow to decrease and affect production efficiency. However, the existing pipeline alloy scale inhibitors have the problem of unsatisfactory scale inhibition effect in actual use. This is because there is a lack of efficient scale inhibition components. The lack of efficient scale inhibition components will not only lead to the above problems, but also the pipeline scale inhibitor may be damaged or worn during long-term use, affecting the scale inhibition effect. First of all, some pipeline scale inhibitors are not ideal in scale inhibition effect. Although physical scale inhibitors can reduce scaling through different principles, their effects may not be satisfactory for some special scaling substances. For example, for some particularly hard scaling substances, the flushing force of the physical scale inhibitor may not be sufficient to completely remove them, so it is necessary to propose a new structure to solve the above technical problems. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model aims to provide an alloy scale inhibitor for cement production pipelines to solve the problems raised in the above-mentioned background technology.
[0004] The utility model is realized through the following technical scheme: a pipeline alloy scale inhibitor for cement production, comprising: a shell, a sleeve assembly and a water pipe, the left end and the right end of the water pipe are symmetrically installed with a connecting flange respectively, the water pipe is provided with two groups, the two groups of water pipes have the same structure, the left end and the right end of the shell are open design, the outer surface of the left end and the outer surface of the right end of the shell are integrally formed with a convex block, a bearing is arranged inside the convex block, a sleeve assembly is rotatably installed inside the shell through the bearing, the sleeve assembly comprises a sleeve body, fins, a clamp and a baffle, a plurality of fins are evenly installed inside the sleeve body, a clamp is installed inside the sleeve body, a baffle is clamped inside the sleeve body through the clamp, a conical hole is formed through the surface of the baffle, a plurality of the fins have the same structure, and a plurality of baffles are arranged.
[0005] As a preferred embodiment, the shell is made of integrally smelted tungsten-molybdenum alloy, and water pipes are installed on the left and right ends of the shell respectively through connecting flanges. A sealing ring is provided at the connection between the connecting flange and the shell, and the interior of the water pipe is connected to the interior of the shell.
[0006] As a preferred embodiment, the water pipe at the left end is a water inlet, and the water pipe at the right end is a water outlet. The inner wall of the bearing inside the convex block on the outer surface of the shell is flush with the inner wall of the shell. A sleeve body is installed inside the shell, and the outer surface of the sleeve body abuts against the inner wall of the shell.
[0007] As a preferred embodiment, the inner wall of the bearing is connected to the outer surface of the sleeve body, and the sleeve body is rotatably installed inside the shell through the bearing. The fins inside the sleeve body are in a semi-heart-shaped structure, and a clamp is installed between every two fins. The fins will drive the sleeve body to rotate due to the impact force of the water flow, thereby changing the shape and speed of the water flow by rotation, thereby forming a rotating vortex to prevent particles in the water from adhering to the inner wall of the sleeve body. Therefore, the flow channel of water for cement production will produce a turbulent effect inside the sleeve body. At the same time, the polyurethane coating applied to its inner wall can form a smooth surface, reduce the degree of adhesion of scaling substances inside the pipeline, and thus reduce the possibility of scaling.
[0008] As a preferred embodiment, a plurality of baffles are installed inside the sleeve body through a plurality of clamps, each of the baffles has the same structure, and a plurality of conical holes are evenly formed on the surface of the baffles, and the smaller diameter end of the conical hole is arranged on the right side surface of the baffle. When the water for cement production hits the baffle, the conical holes on the surface of the baffle can form a jet flow, thereby increasing the fluid velocity and flushing force of the water for cement production, and can effectively flush the inside of the sleeve body, making it difficult for scale to adhere to the inside of the sleeve body.
[0009] As a preferred embodiment, the baffle is made of a copper-based catalyst alloy, the inner wall of the sleeve body and the outer surface of the fin are coated with a polyurethane coating, and the inner wall of the sleeve body is aligned parallel to the inner wall of the water pipe.
[0010] After adopting the above technical scheme, the beneficial effects of the utility model are as follows: by setting a sleeve assembly, the sleeve assembly includes a sleeve body, fins, a clamp and a baffle, the left end and the right end of the outer surface of the shell are respectively provided with protrusions, and the inner part of the protrusion is provided with a bearing, and the sleeve body is rotatably installed in the inner part of the shell through the bearing, and the inner wall of the sleeve body is evenly provided with a plurality of fins, and the outer surfaces of the fins and the sleeve body are coated with a polyurethane coating, when the water for cement production enters the inner part of the sleeve body through the water pipe, it will impact the fins, and at this time, the fins will be due to the impact force of the water flow. The sleeve body is driven to rotate, thereby changing the shape and speed of the water flow through rotation, thereby forming a rotating vortex to prevent particles in the water from adhering to the inner wall of the sleeve body. Therefore, the flow channel of water for cement production will produce a turbulent effect inside the sleeve body. At the same time, the polyurethane coating applied to its inner wall can form a smooth surface, reducing the degree of adhesion of scaling substances inside the pipe, thereby reducing the possibility of scaling, extending the service life of the pipe, reducing the frequency of maintenance and replacement, keeping the inside of the sleeve body clean, and increasing the fluidity of water for cement production.
[0011] By setting a baffle, a plurality of clamps are evenly installed inside the sleeve body, and a plurality of baffles are installed inside the sleeve body through the clamps. A plurality of conical holes are opened on the surface of the baffle, and the end with a smaller diameter of the conical hole is set on the right side surface of the baffle. When the water for cement production hits the baffle, the conical holes on the surface of the baffle can form a jet flow, thereby increasing the fluid velocity and flushing force of the water for cement production, and can effectively flush the inside of the sleeve body, making it difficult for scaling to adhere to the inside of the sleeve body. At the same time, the baffle itself can cause turbulence of the water for cement production. The generation of turbulence can destroy the formation of scaling substances, and further reduce blockage and aggregation inside the sleeve body. BRIEF DESCRIPTION OF THE DRAWINGS

The sleeve assembly 200 includes a sleeve body 210, fins 220, a clamp 230 and a baffle 240. A plurality of fins 220 are evenly installed inside the sleeve body 210. A clamp 230 is installed inside the sleeve body 210. A baffle 240 is clamped inside the sleeve body 210 through the clamp 230. A conical hole 241 is formed through the surface of the baffle 240. The plurality of fins 220 have the same structure, and a plurality of baffles 240 are provided.
[0020] See also Figure 1 , Figure 2 As an embodiment of the utility model: the shell 100 is made of tungsten-molybdenum alloy melted in one piece, the left end and the right end of the shell 100 are respectively installed with water pipes 300 through connecting flanges 310, and a sealing ring is provided at the connection between the connecting flange 310 and the shell 100, and the inside of the water pipe 300 is connected to the inside of the shell 100;
[0021] The left end water pipe 300 is a water inlet, and the right end water pipe 300 is a water outlet. The inner wall of the bearing 111 inside the protrusion 110 on the outer surface of the shell 100 is flush with the inner wall of the shell 100. The sleeve body 210 is installed inside the shell 100, and the outer surface of the sleeve body 210 abuts against the inner wall of the shell 100.
[0022] The inner wall of the bearing 111 is connected to the outer surface of the sleeve body 210. The sleeve body 210 is rotatably installed inside the housing 100 through the bearing 111. The fins 220 inside the sleeve body 210 are in a half heart-shaped structure, and a clamp 230 is installed between every two fins 220.
[0023] When in use, when the water for cement production enters the sleeve body 210 through the water pipe 300 at the left end, it will impact the fins 220. At this time, the fins 220 will drive the sleeve body 210 to rotate inside the shell 100 due to the impact force of the water flow, thereby changing the shape and speed of the water flow by rotation, thereby forming a rotating vortex to prevent particles in the water from adhering to the inner wall of the sleeve body 210. Therefore, the flow channel of the water for cement production will produce a turbulent effect inside the sleeve body 210. At the same time, the polyurethane coating applied to its inner wall can form a smooth surface, reduce the degree of adhesion of scaling substances inside the pipe, thereby reducing the possibility of scaling, extending the service life of the pipe, reducing the frequency of maintenance and replacement, keeping the inside of the sleeve body 210 clean, and increasing the fluidity of the water for cement production.
[0024] See also Figure 1 , Figure 2 As an embodiment of the utility model: a plurality of baffles 240 are installed inside the sleeve body 210 through a plurality of clamps 230, each baffle 240 has the same structure, and a plurality of tapered holes 241 are uniformly formed through the surface of the baffle 240, and the smaller diameter end of the tapered hole 241 is arranged on the right side surface of the baffle 240;
[0025] The baffle 240 is made of a copper-based catalyst alloy, the inner wall of the sleeve body 210 and the outer surface of the fin 220 are coated with a polyurethane coating, and the inner wall of the sleeve body 210 is aligned parallel to the inner wall of the water pipe 300;
[0026] When the cement production water enters the sleeve body 210 through the water pipe 300 at the left end and impacts the fin 220, the cement production water will also impact the baffle 240. At this time, the tapered hole 241 on the surface of the baffle 240 can make the water flow form a jet flow, thereby increasing the fluid velocity and flushing force of the cement production water inside the sleeve body 210, so that it can effectively flush the inside of the sleeve body 210, making it difficult for scale to adhere to the inner wall of the sleeve body 210. At the same time, the baffle 240 itself can cause turbulence of the cement production water. When the water flow impacts the baffle 240, part of the water flow will pass through the tapered hole 241 to form a jet flow water body, and part of the water flow will be blocked by the impenetrable part of the baffle 240 to form a backflow. Because the subsequent new water flow continues to enter, turbulence is formed at the baffle 240. The generation of turbulence can destroy the formation of scaling substances and further reduce blockage and accumulation inside the sleeve body 210.
[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
