Description

Technical Field

[0001] This application relates to alkali melting kettle feeding technology, and more particularly to an alkali melting kettle feeding device. Background Technology

[0002] In the indigo production process, after producing powdered potassium aniline acetate and liquid sodium amino, a mixture of molten NaOH and KOH is added to the alkali melting kettle as a reaction solvent. Then, liquid sodium amino is added to the alkali melting kettle. Subsequently, powdered potassium aniline acetate is added to the alkali melting kettle in batches through a feeding device to generate potassium indophenol, as well as byproducts (ammonia and sodium oxide). Then, potassium indophenol undergoes an oxidation reaction to produce indigo.

[0003] Currently, a common feeding device for alkali fusion kettles includes a hopper, with a screw conveyor connected to the lower end of the hopper. The discharge port of the screw conveyor is connected to the alkali fusion kettle. In use, potassium aniline acetate is pre-added to the hopper, and then transported to the alkali fusion kettle by the screw conveyor for feeding.

[0004] However, in actual production, potassium aniline acetate is obtained by drum drying after concentration, which makes it easy for potassium aniline acetate to contain lumps. Moreover, the existing screw conveyor cannot effectively deal with the lumps during the process of transporting potassium aniline acetate. The lumped potassium aniline acetate is directly added to the alkali melting kettle for reaction. When the lumped potassium aniline acetate enters the alkali melting kettle, the reaction time with other materials is long, which affects the efficiency of the alkali melting reaction. Utility Model Content

[0005] This application provides a feeding device for an alkali melting kettle to solve the problem that when agglomerated potassium aniline enters the alkali melting kettle, the reaction time with other materials is long, which affects the efficiency of the alkali melting reaction.

[0006] This application provides a feeding device for an alkali melting kettle, including a hopper, the lower end of which is connected to a cylinder, a rotating shaft is provided inside the cylinder, the rotating shaft is connected to a motor that can drive it to rotate, and a spiral blade is fixed on the rotating shaft.

[0007] One end of the cylinder is connected to a wire mesh cylinder that is concentric with and communicates with it;

[0008] The inside of the mesh cylinder is equipped with a rotatable crushing structure for breaking up clumps.

[0009] Optionally, the mesh cylinder is rotatably connected to the cylinder body in a sealed manner, and the mesh cylinder is fixedly connected to the rotating shaft.

[0010] Optionally, the rotation direction of the mesh cylinder is opposite to the rotation direction of the crushing structure.

[0011] Optionally, the crushing structure includes a drive shaft, on which a set of crushing blades located inside the mesh cylinder is fixed. One end of the drive shaft is rotatably connected to a rotating shaft, and the other end of the drive shaft extends out of the mesh cylinder and is rotatably connected to the mesh cylinder.

[0012] The other end of the drive shaft is connected to the mesh cylinder via a reverse transmission mechanism.

[0013] Optionally, the reverse transmission mechanism includes an internal gear ring, which meshes with gear I, and gear I meshes with gear II, which is concentric with the internal gear ring;

[0014] The internal gear ring is concentrically and fixedly connected to the mesh cylinder, and the gear II is fixedly connected to the other end of the drive shaft;

[0015] The gear I is rotatably connected to a support, and the support is fixedly connected to the cylinder.

[0016] Optionally, the support is a hollow box structure with an open bottom. The support is sleeved on the outside of the mesh cylinder. One end of the support is sealed and fixedly connected to the cylinder body, and the other end of the support is fixed with an installation shaft, which is rotatably connected to gear I.

[0018] Optionally, one end of the internal toothed ring is fixedly connected to the mesh cylinder seal, and the other end of the internal toothed ring is rotatably connected to the support seal.

[0019] The alkali fusion kettle feeding device provided in this application has a cylinder connected to the lower end of a hopper. Inside the cylinder is a rotating shaft connected to a motor that drives its rotation. Spiral blades are fixed on the rotating shaft. One end of the cylinder is connected to a concentric mesh cylinder. The mesh cylinder has a rotatable crushing structure for breaking up agglomerates. This allows for the addition of powdered potassium aniline acetate to the alkali fusion kettle, with potassium aniline acetate pre-added to the hopper. The potassium aniline acetate then enters the cylinder from the hopper, and the rotating spiral blades transport the potassium aniline acetate to the mesh cylinder. Inside, the crushing structure rotates simultaneously, and powdered potassium aniline acetate falls directly from the mesh cylinder into the molten alkali tank. The crushing structure breaks down the agglomerated potassium aniline acetate. After the agglomerated potassium aniline acetate is broken down to a certain particle size, it falls from the mesh cylinder into the alkali melting kettle to react. Compared with the existing alkali melting kettle feeding method, this method can break down the agglomerated potassium aniline acetate while adding it to the alkali melting kettle, solving the problem of long reaction time when the agglomerated potassium aniline acetate enters the molten alkali kettle and reacts with other materials, thus improving the efficiency of the alkali melting reaction.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0028] like Figures 1-5 As shown:

[0029] An embodiment of this application provides a feeding device for an alkali fusion reactor, comprising a hopper 1, the lower end of which is fixedly connected to a cylinder 2. Specifically, a feed inlet is provided at the upper left end of the cylinder 2, and the feed inlet is sealed and fixedly connected to the lower end of the hopper 1. A rotating shaft 3 is provided inside the cylinder 2, and a motor 4 capable of driving its rotation is connected to the rotating shaft 3. A spiral blade 5 is fixed on the rotating shaft 3. Specifically, the left end of the rotating shaft 3 is rotatably connected to the left end of the cylinder 2 via a bearing, and the left end of the rotating shaft 3 is connected to the motor 4, which is fixed to the left end of the cylinder 2.

[0030] One end of the cylindrical body 2 is connected to a concentric mesh cylinder 6. Specifically, the cylindrical body 2 is a cylindrical structure with an opening at the right end, and the mesh cylinder 6 is a cylindrical structure with an opening at the left end. The circumferential wall of the mesh cylinder 6 is a mesh structure, and the left end of the mesh cylinder 6 is connected to the right end of the cylindrical body 2. The interior of the mesh cylinder 6 is provided with a rotatable crushing structure 7 for breaking up agglomerates.

[0031] In this embodiment, the mesh cylinder 6 is located inside the alkali melting kettle 12, and the cylinder body 2 is fixedly connected to the alkali melting kettle 12.

[0032] In use, potassium aniline acetate is first added to hopper 1. Then, the potassium aniline acetate enters cylinder 2 from hopper 1. Motor 4 drives shaft 3 to rotate, shaft 3 drives spiral blade 5 to rotate, and spiral blade 5 transports potassium aniline acetate into mesh cylinder 6. At the same time, crushing structure 7 rotates, and powdered potassium aniline acetate falls directly from mesh cylinder 6 into alkali melting tank. Crushing structure 7 crushes the agglomerated potassium aniline acetate. After the agglomerated potassium aniline acetate is crushed to a certain particle size, it falls from mesh cylinder 6 into alkali melting kettle 12 for reaction.

[0033] The alkali melting kettle feeding device provided in this embodiment has a mesh cylinder 6 connected to one end of the cylinder 2 and concentric with it. The mesh cylinder 6 has a rotatable crushing structure 7 for breaking up agglomerates, so that while adding potassium aniline acetate to the alkali melting kettle 12, the agglomerated potassium aniline acetate can be crushed. This solves the problem that the reaction time of agglomerated potassium aniline acetate with other materials is long after entering the alkali melting kettle, and improves the efficiency of the alkali melting reaction.

[0034] In some embodiments of this application, the mesh cylinder 6 and the cylinder body 2 are rotatably connected by a sealed bearing, and the mesh cylinder 6 is fixedly connected to the rotating shaft 3. Specifically, the right end of the rotating shaft 3 extends into the inside of the mesh cylinder 6, and a connecting frame 8 is fixed to the right end of the rotating shaft 3. The connecting frame 8 is fixedly connected to the inner wall of the mesh cylinder 6, which not only supports the rotating shaft 3, but also allows the rotating shaft 3 to drive the mesh cylinder 6 to rotate synchronously with it through the connecting frame 8. Moreover, after the mesh cylinder 6 rotates, the discharge efficiency of the mesh cylinder 6 can be improved.

[0035] In some embodiments of this application, the rotation direction of the mesh cylinder 6 is opposite to the rotation direction of the crushing structure 7, in order to improve the crushing efficiency of agglomerates.

[0036] In some embodiments of this application, the crushing structure 7 includes a drive shaft 701, on which a crushing blade assembly 702 located inside the mesh cylinder 6 is fixed. One end of the drive shaft 701 is rotatably connected to the rotating shaft 3, and the other end of the drive shaft 701 extends out of the mesh cylinder 6 and is rotatably connected to the mesh cylinder 6. Specifically, the left end of the drive shaft 701 is rotatably connected to the right end of the rotating shaft 3 via a bearing, and the right end of the drive shaft 701 is rotatably connected to the right end of the mesh cylinder 6, so that the drive shaft 701 can rotate independently relative to the rotating shaft 3 and the mesh cylinder 6.

[0037] In this embodiment, the crushing blade assembly 702 is composed of multiple crushing blade discs.

[0038] The other end of the drive shaft 701 is connected to the mesh cylinder 6 via a reverse transmission mechanism 9. Specifically, the right end of the drive shaft 701 is connected to the right end of the mesh cylinder 6 via the reverse transmission mechanism 9, and the mesh cylinder 6 drives the drive shaft 701 to rotate in the opposite direction via the reverse transmission mechanism 9.

[0039] When in use, after the mesh cylinder 6 rotates, the mesh cylinder 6 drives the drive shaft 701 to rotate in the opposite direction through the reverse transmission mechanism 9. The drive shaft 701 drives the crushing knife group 702 to rotate synchronously with it. That is, the crushing knife group 702 rotates in the opposite direction relative to the mesh cylinder 6. The rotating crushing knife group 702 crushes the lumps. Moreover, after the crushing knife group 702 rotates in the opposite direction relative to the mesh cylinder 6, it can improve the crushing efficiency of the lumps.

[0040] In some embodiments of this application, the reverse transmission mechanism 9 includes an internal gear ring 901, which meshes with a gear I 902, and the gear I 902 meshes with a gear II 903 that is concentric with the internal gear ring 901.

[0041] The internal gear ring 901 is concentrically and fixedly connected to the mesh cylinder 6. Specifically, the internal gear ring 901 is fixedly connected to the right end of the mesh cylinder 6. The gear II 903 is fixedly connected to the other end of the drive shaft 701. Specifically, the gear II 903 is fixedly connected to the right end of the drive shaft 701.

[0042] The gear I902 is rotatably connected to the support 10, and the support 10 is fixedly connected to the cylinder 2 to support the gear I902.

[0043] In use, the mesh cylinder 6 drives the internal gear ring 901 to rotate in the same direction as it, the internal gear ring 901 drives gear I 902 to rotate in the same direction as it, gear I 902 drives gear II 903 to rotate in the opposite direction as it, gear II 903 drives the drive shaft 701 to rotate in the same direction as it, and the drive shaft 701 drives the crushing blade assembly 702 to rotate in the same direction as it, thus realizing that the crushing blade assembly 702 rotates in the opposite direction relative to the mesh cylinder 6.

[0044] In some embodiments of this application, the support 10 is a hollow box structure with an open lower end. The support 10 is fitted onto the outside of the mesh cylinder 6, with a gap between the support 10 and the mesh cylinder 6. One end of the support 10 is sealed and fixedly connected to the cylinder 2, and the other end of the support 10 is fixedly connected to an installation shaft 11, which is rotatably connected to gear I 902. Specifically, the left end of the support 10 is sealed and fixedly connected to the right end of the cylinder 2, and the right end of the support 10 is fixedly connected to the installation shaft 11, which is rotatably connected to gear I 902 via a bearing.

[0045] In this embodiment, by setting a support 10 with a hollow box structure and an open bottom, not only can the gear I 902 be supported, but also when the mesh cylinder 6 rotates, the material flowing out of the mesh cylinder 6 first enters the support 10 and finally falls into the alkali melting kettle 12 from the lower opening of the support 10, thereby preventing the material flowing out of the mesh cylinder 6 from splashing around in the alkali melting kettle 12.

[0046] In some embodiments of this application, the other end of the drive shaft 701 is rotatably connected to the other end of the support 10. Specifically, the right end of the drive shaft 701 is rotatably connected to the right end of the support 10 via a bearing, which is used to support the drive shaft 701 and improve the stability of the drive shaft 701.

[0047] In some embodiments of this application, one end of the internal gear ring 901 is sealed and fixedly connected to the mesh cylinder 6, and the other end of the internal gear ring 901 is sealed and rotatably connected to the support 10. Specifically, the left end of the internal gear ring 901 is sealed and fixedly connected to the right end of the mesh cylinder 6, and the right end of the internal gear ring 901 is sealed and rotatably connected to the right end of the support 10 through a sealed bearing, thereby preventing material contamination of the internal gear ring 901, gear I 902, and gear II 903.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
