Description

Technical Field

[0001] The utility model provides a water blowing and settling pipeline, belonging to the technical field of crystal production and processing. Background Art

[0002] Crystallization methods can be mainly divided into two categories. The first type: crystallization by removing part of the solvent: even if part of the solvent evaporates or vaporizes, the solution is concentrated to supersaturation and crystallization occurs. It is used for substances whose solubility decreases slightly with decreasing temperature, such as sodium chloride, potassium chloride, potassium carbonate, etc. The second type: crystallization without removing the solvent, even if the solution is cooled to supersaturation and crystallization occurs. It is used for substances whose solubility decreases significantly with decreasing temperature, such as potassium nitrate, sodium nitrate, magnesium sulfate, etc. At present, when obtaining crystals through a crystallization furnace, in order to separate the solid crystals mixed in the slurry solution, it is usually necessary to use a slurry pipeline to transport the slurry solution to the next process.

[0003] The existing slurry pipeline can basically meet the use needs, but when the slurry pipeline is used to transport the slurry solution mixed with solid crystals, since the density of the solid crystals is usually greater than the density of the slurry solution, it is inevitable that the solid crystals will settle at the bottom of the slurry pipeline during the transportation process. As the settled crystals slowly accumulate, the transportation rate of the slurry solution mixed with solid crystals will be affected, and even blockage and inability to transport will occur. Based on this, the utility model provides a water blowing sedimentation pipeline. Utility Model Content

[0004] The technical problem solved by the utility model is that when the slurry pipeline is transporting the slurry solution, solid crystals will settle at the bottom of the slurry pipeline. As the settled crystals slowly accumulate, the transport rate of the slurry solution mixed with the solid crystals will be affected, and even blockage will occur and the slurry solution cannot be transported.

[0005] In order to solve the technical problem, the technical solution provided by the utility model is: a water blowing sedimentation pipeline, including a slurry pipeline, a gas supply main pipe is fixedly provided on the top of the slurry pipeline, and a plurality of blowing pipes inserted into the slurry pipeline are equidistantly provided at the bottom of the gas supply main pipe, and a fixed plate is provided at the port of the blowing pipe, and a guide cone placed on the inner side of the blowing pipe is rotatably connected to the side wall of the fixing plate, and a spiral guide protrusion is provided on the cone wall of the guide cone.

[0006] Furthermore, the gas transmission main pipe is connected to an external fan.

[0007] Furthermore, the top of the slurry pipeline is fixedly connected to the gas transmission main pipe by a support block.

[0008] Furthermore, the fixing plate is fixedly arranged between the inner side walls of the port of the air blowing pipe, and the tip of the guide cone is placed on a side away from the fixing plate.

[0009] Furthermore, the side wall of the guide cone is provided with a rotating shaft rotatably connected to the side wall of the fixing plate.

[0010] Furthermore, the maximum diameter of the guide cone is slightly larger than 1 / 2 of the diameter of the blowing pipe.

[0011] Beneficial effects of the utility model:

[0012] Under the joint action of the gas main pipe, the air blowing pipe, the guide cone, etc., when air is blown into the slurry pipe from the air blowing pipe, the wind will swirl and be injected into the slurry pipe from all sides of the guide cone, so that the injected air will scatter in the slurry pipe. The swirling wind blowing into the slurry pipe can effectively accelerate the flow rate of the slurry solution, and can quickly blow up and suspend the crystals settled at the bottom of the slurry pipe, effectively preventing blockage.

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] According to the attached Figure 1 , 2 As shown: the utility model provides a water blowing sedimentation pipeline: it includes a slurry pipeline 1, a gas supply pipe 2 connected to an external fan is fixedly provided on the top of the slurry pipeline 1, the top of the slurry pipeline 1 and the gas supply pipe 2 are fixedly connected by a support block 7, which plays a role in fixing the gas supply pipe 2 on the slurry pipeline 1, and a plurality of blowing pipes 3 inserted into the slurry pipeline 1 are equidistantly provided at the bottom of the gas supply pipe 2. By starting the external fan, the wind generated by the fan is transported to the gas supply pipe 2, and the wind is blown into the slurry pipeline 1 through the blowing pipes 3. The wind blown into the slurry pipeline 1 can accelerate the flow rate of the slurry solution, and blow up and suspend the crystals settled at the bottom of the slurry pipeline, effectively preventing blockage.

[0020] According to the attached Figure 2 , 3 4: The port of the air blowing pipe 3 is provided with a fixing plate 4, which is fixedly arranged between the inner side walls of the port of the air blowing pipe 3, and the side wall of the fixing plate 4 is rotatably connected with a guide cone 5 placed on the inner side of the air blowing pipe 3, and a spiral guide protrusion 6 is provided on the cone wall of the guide cone 5, and the tip of the guide cone 5 is placed on the side away from the fixing plate 4, and the side wall of the guide cone 5 is provided with a rotating shaft 8 rotatably connected to the side wall of the fixing plate 4 to ensure that the guide cone 5 can effectively rotate, and the maximum diameter of the guide cone 5 is slightly larger than 1 / 2 of the diameter of the air blowing pipe 3, so as to ensure that the air blown out from the air blowing pipe 3 The gas can be effectively injected into the slurry pipe 1 from the four sides of the guide cone 5. When the wind is blown into the slurry pipe 1 from the air blowing pipe 3, the wind will first pass through the guide cone 5, and the wind force will drive the guide cone 5 to rotate. When the wind blows into the slurry pipe 1 along the spiral guide protrusion 6, the wind will be injected into the slurry pipe 1 from all sides of the guide cone 5 as the guide cone 5 rotates, so that the injected wind is scattered in the slurry pipe 1, which can not only greatly improve the utilization rate of the wind, but also make the crystals settled at the bottom of the slurry pipe be quickly blown up and suspended.

[0021] Principle of the utility model

[0022] During use, when the slurry pipeline 1 is transporting the slurry solution mixed with solid crystals, the wind generated by the external fan is transported to the gas supply main pipe 2 by starting the external fan, and the wind is blown into the slurry pipeline 1 through the blowing pipe 3. When the wind is blown into the slurry pipeline 1 from the blowing pipe 3, the wind will first pass through the guide cone 5, and the wind force will drive the guide cone 5 to rotate. When the wind force blows into the slurry pipeline 1 along the spiral guide protrusion 6, as the guide cone 5 rotates, the wind will be injected into the slurry pipeline 1 from all sides of the guide cone 5, so that the injected air is scattered in the slurry pipeline 1. The swirling wind blowing into the slurry pipeline 1 can effectively accelerate the flow rate of the slurry solution, and can make the crystals settled at the bottom of the slurry pipeline be quickly blown up and suspended, effectively preventing blockage.
