Description

Technical Field

[0001] The utility model relates to the technical field of solvent production additive adding equipment, in particular to a cresol production additive uniform feeding mechanism. Background Art

[0002] Cresol is an organic chemical with the molecular formula C7H8O. It is a clear liquid that is almost colorless, light purple or light brown. It has a phenol-like odor and a slight burnt odor. The color gradually darkens after long-term storage or exposure to sunlight. The saturated aqueous solution shows a neutral or weakly acidic reaction. It is a raw material for manufacturing surfactants, lubricating oils, synthetic material additives, and dye intermediates. Cresol is often added with catalysts using a feed tank.

[0003] The traditional feeding tank device only injects the additives into the reaction tank when in use, and cannot achieve uniform addition, resulting in the additives not being able to react quickly and fully in the reaction tank, affecting the quality of cresol production. In addition, without a matching mixing device, it is even more difficult to achieve effective, sufficient and rapid mixing. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the utility model is to provide a uniform feeding mechanism for cresol production additives, which can add cresol production additives uniformly over a large range, thereby greatly improving the sufficiency and efficiency of the reaction.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a uniform feeding mechanism for cresol production additives, comprising a hollow shaft and a reaction tank, wherein the hollow shaft is rotatably mounted inside the reaction tank, a feeding assembly is arranged on the hollow shaft, the feeding assembly comprises a plurality of mixing tubes fixedly mounted on the hollow shaft, the mixing tube adopts a hollow tube connected to the hollow shaft, and a liquid inlet hole and a liquid outlet hole are arranged on the mixing tube, and also comprises a uniform bulking assembly, the uniform bulking assembly can disperse the additives flowing out through the liquid outlet hole, a liquid adding hopper connected to the hollow shaft is arranged at the top end of the hollow shaft, a pulley is arranged on one end of the hollow shaft close to the liquid adding hopper, a driving mechanism capable of driving the hollow shaft to rotate is arranged on the reaction tank, the uniform bulking assembly comprises a bulking tube rotatably mounted on the mixing tube, the bulking tube is V-shaped, and its included angle is an obtuse angle, the part of the bulking tube in contact with the mixing tube is arranged perpendicular to the mixing tube, and the uniform bulking assembly also comprises a turbine blade fixedly mounted on the bulking tube near the mixing tube.

[0006] As a preferred technical solution of the utility model, a baffle is installed inside the hollow shaft, and the baffle is located below the position where the multiple mixing tubes are connected to the hollow shaft.

[0007] As a preferred technical solution of the utility model, multiple mixing plates are installed on each of the multiple mixing tubes.

[0008] As a preferred technical solution of the utility model, the multiple mixing plates are all installed at an angle, and the inclination directions of the multiple mixing plates on the same mixing tube are arranged alternately.

[0009] By using multiple mixing plates arranged at an angle, when the mixing tube is driven to rotate, the mixing plates will push the solution inside the reaction tank to shake, and the mixing plates in different inclination directions can further increase the mixing range of the solution.

[0010] As a preferred technical solution of the utility model, the horizontal position of the liquid inlet hole is higher than the position of the liquid outlet hole, and the position of the liquid inlet hole is lower than the height of the solution inside the reaction tank.

[0011] As a preferred technical solution of the utility model, a liquid collecting cover for collecting the solution is installed at the liquid inlet.

[0012] When in use, the mixing tube is driven to rotate by the hollow shaft, and the bulk material pipe arranged tangentially to its motion trajectory will rotate itself driven by the turbine blades. The turbine blades rotate when passing through the water flow, thereby driving the V-shaped bulk material pipe to rotate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] Mixing plates with different inclination directions can increase the mixing range of the solution, thereby improving the mixing efficiency of the solution and additives, shortening the reaction time, spraying the additives over a wider range, and can also improve the mixing effect and efficiency of the solution inside the reaction tank through the bulk pipe, which is more conducive to the rapid and full reaction of the additives.

The solution in the liquid tank 1 is stirred. When it is necessary to add additives, it is only necessary to add the additives into the liquid adding bucket 3. The additives will enter different mixing tubes 5 through the connection between the multiple mixing tubes 5 and the hollow shaft 2, and then be discharged through the liquid outlet 11. At this time, the rotation of the mixing tube 5 will cause the solution to enter the mixing tube 5 through the liquid inlet 10 and be discharged through the liquid outlet 11, forming a stable flow direction, further driving the additives to continuously flow into the reaction tank 1, and there is no need to add a pump-type conveying equipment separately to promote the discharge of the additives. It also includes a uniform bulking component, which can disperse the additives flowing out through the liquid outlet 11. The continuously rotating mixing tube 5 can drive the additives to be dispersed to more locations for addition, with a wider range, which is more conducive to the reaction of the additives, and the additives are further dispersed by setting a uniform dispersion component.

[0021] Other specific implementation methods of the present invention are as follows: Figure 2-4 It can be seen that the horizontal position of the liquid inlet 10 is higher than that of the liquid outlet 11, and the position of the liquid inlet 10 is lower than the height of the solution inside the reaction tank 1. A liquid collecting cover 7 for collecting the solution is installed at the liquid inlet 10. A larger liquid collecting cover 7 can allow more solution to enter the mixing tube 5, thereby pushing the additive to be sprayed out from the liquid outlet 11, further improving the addition range of the additive, and the higher position of the liquid inlet 10 can drive the additive more effectively and can greatly reduce the residual additive.

[0022] Other specific implementation methods of the present invention are as follows: Figure 2-4It can be seen that multiple mixing plates 6 are installed on the multiple mixing tubes 5, and the multiple mixing plates 6 are installed at an angle, and the inclination directions of the multiple mixing plates 6 on the same mixing tube 5 are alternately arranged.

[0023] Other specific implementation methods of the present invention are as follows: Figure 2-4 It can be seen that the uniform bulk material assembly includes a bulk material tube 8 rotatably mounted on the mixing tube 5, the bulk material tube 8 is V-shaped, and the angle thereof is an obtuse angle, the portion of the bulk material tube 8 in contact with the mixing tube 5 is arranged perpendicular to the mixing tube 5, and the uniform bulk material assembly also includes a turbine blade 9 fixedly mounted on the bulk material tube 8 near the mixing tube 5. When in use, the mixing tube 5 is driven to rotate by the hollow shaft 2, and the bulk material tube 8 arranged tangent to its motion trajectory will rotate itself driven by the turbine blade 9. The turbine blade 9 rotates when passing through the water flow, thereby driving the V-shaped bulk material tube 8 to rotate, which can not only spray the additive over a wider range, but also improve the mixing effect and efficiency of the solution inside the reaction tank 1 under the action of the bulk material tube 8.
