Description

Technical Field

[0001] The present application relates to mixing technology, and in particular to a conical mixer. Background Art

[0002] In the production process of graphite negative electrode materials, a conical mixer is typically used to mix powdered raw materials. Currently, a commonly used conical mixer includes an inverted conical barrel with a motor and multiple feeding ports at the top. A rotatable arm is located at the inner top of the barrel, and the rotating wall is an inverted T-shaped structure. The horizontal section of the arm is equipped with spiral structures that can rotate parallel to the barrel's generatrix. The motor drives the vertical section of the arm and the spiral structure to rotate simultaneously through a transmission mechanism. A discharge valve is located at the bottom of the barrel. During use, all raw materials are typically added directly into the barrel through multiple feeding ports at once, and then stirred and mixed.

[0003] However, the position of the feeding port of the conical mixer is fixed, that is, the dropping point of each raw material is fixed. Therefore, after the raw materials are directly added to the cylinder at one time, each raw material is accumulated in the cylinder, and the accumulation position of each raw material is different. It usually takes a long mixing time to fully mix all the raw materials, which leads to a long mixing time and low efficiency. Utility Model Content

[0004] The present application provides a conical mixer to solve the problem that conventional conical mixers generally require a long mixing time to fully mix powdered materials when mixing powdered materials.

[0005] The present application provides a conical mixer, comprising an inverted conical barrel, a motor provided at the upper end of the barrel, an inverted T-shaped rotating arm provided at the inner top of the barrel, a spiral structure connected to both ends of the horizontal section of the rotating arm, the motor being able to drive the vertical section of the rotating arm and the spiral structure to rotate simultaneously through a transmission mechanism, and a discharge valve provided at the bottom of the barrel;

[0006] A material guide piece fixedly connected to the cylinder is sleeved on the vertical section of the rotating arm, and a first inverted cone-shaped annular gap is formed between the material guide piece and the vertical section of the rotating arm, and a stirring structure fixedly connected to the vertical section of the rotating arm is provided in the first annular gap;

[0007] The upper end of the cylinder is provided with a plurality of feeding ports located above the first annular gap.

[0008] Optionally, a cylindrical feeding pipe is fixed to the lower end of the material guide member, the feeding pipe is sleeved on the vertical section of the rotating arm and forms a second annular gap with the vertical section, and the stirring structure extends into the second annular gap.

[0009] Optionally, the stirring structure includes a mounting sleeve, on which a plurality of stirring components distributed vertically are fixed, and the stirring components are composed of a plurality of stirring blades distributed in an annular shape;

[0010] The mounting sleeve is fixed on the vertical section of the rotating arm.

[0011] Optionally, two upper and lower adjacent stirring blades are staggered.

[0012] Optionally, a sealing cover is detachably fixed to the upper end of the feeding port.

[0013] Optionally, a plurality of support members distributed in an annular shape are fixed on the outer wall of the cylinder.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] The conical mixer provided by the present application is provided with a material guide piece fixedly connected to the cylinder body on the vertical section of the rotating arm, and a first inverted cone-shaped annular gap is formed between the material guide piece and the vertical section of the rotating arm, and a stirring structure fixedly connected to the vertical section of the rotating arm is provided in the first annular gap, and a plurality of feeding ports located above the first annular gap are provided at the upper end of the cylinder body, so that when feeding into the cylinder body, all powdered raw materials first fall into the inverted cone-shaped first annular gap from the feeding ports at the same time, and at the same time, the vertical section of the rotating arm is rotated, and the vertical section of the rotating arm drives the stirring structure to rotate, and all powdered raw materials are mixed. After falling into the first annular gap, all the powdered raw materials fall onto the material guide member and gather along the material guide member to the middle position of the first annular gap. At the same time, the rotating stirring structure stirs the powdered raw materials in the first annular gap, so that all the powdered raw materials are pre-mixed. Finally, the pre-mixed powder falls from the bottom of the material guide member to the lower part of the cylinder and is fully mixed by the two spiral structures. Compared with the existing cylinder feeding method, the powdered raw materials can be pre-mixed while feeding. On the premise of ensuring that the powdered raw materials are fully mixed, the mixing time can be shortened and the mixing efficiency can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts also fall within the scope of protection of this application.

[0023] like Figures 1-4 As shown:

[0024] A conical mixer provided in one embodiment of the present application comprises an inverted conical barrel 1, with a motor 2 mounted at the upper end of the barrel 1. An inverted T-shaped rotating arm 3 is provided at the inner top of the barrel 1, with spiral structures 4 connected to both ends of the horizontal section 301 of the rotating arm 3. The motor 2, through a transmission mechanism, drives the vertical section 302 of the rotating arm 3 and the spiral structure 4 to rotate simultaneously, allowing the two spiral structures 4 to rotate while revolving. A discharge valve 5 is mounted at the bottom of the barrel 1.

[0025] Specifically, the spiral structure 4 includes a rotating shaft 401 , which is rotatably connected to the end of the horizontal section 301 of the rotating arm 3 , and the rotating shaft 401 is distributed along the generatrix of the cylinder 1 , and a spiral blade 402 is fixed on the rotating shaft 401 .

[0026] Furthermore, the two rotating shafts 401 have different lengths, that is, the two spiral structures 4 have different lengths, so that the two spiral structures 4 will not interfere with each other inside the cylinder 1.

[0027] The vertical section 302 of the rotating arm 3 is sleeved with a material guide 6 fixedly connected to the cylinder 1. Specifically, the upper end of the material guide 6 is fixedly connected to the inner upper end of the cylinder 1.

[0028] A first inverted conical annular gap 7 is formed between the material guide 6 and the vertical section 302 of the rotating arm 3. Specifically, the material guide 6 is an inverted conical annular structure. A stirring structure 8 fixedly connected to the vertical section 302 of the rotating arm 3 is provided in the first annular gap 7.

[0029] The upper end of the cylinder 1 is provided with a plurality of feeding ports 9 located above the first annular gap 7 .

[0030] In this embodiment, the manner in which the motor 2 drives the vertical section 302 of the rotating arm 3 and the spiral structure 4 to rotate simultaneously through the transmission mechanism is a prior art and will not be described in detail.

[0031] In this embodiment, the cylinder 1 is fixed on a bracket for supporting the cylinder 1 , the cylinder 1 is located below the raw material storage bin, and a feeding port 9 is connected to a raw material storage bin.

[0032] When in use, all powdered raw materials first fall into the inverted cone-shaped first annular gap 7 from the feeding port 9 at the same time, and the motor 2 is started at the same time. The motor 2 drives the vertical section 302 of the rotating arm 3 and the two spiral structures 4 to rotate through the transmission mechanism, that is, the two spiral structures 4 rotate while revolving around the vertical section 302 of the rotating arm 3. After the vertical section 302 of the rotating arm 3 rotates, it drives the stirring structure 8 to rotate synchronously with it. After all the powdered raw materials fall into the first annular gap 7, all the powdered raw materials fall onto the material guide 6 and converge along the material guide 6 to the lower end middle position of the first annular gap 7. At the same time, the rotating stirring structure 8 stirs the powdered raw materials flowing in the first annular gap 7 to pre-mix all the powdered raw materials. Finally, the pre-mixed powder falls from the bottom of the material guide 6 to the lower part of the cylinder 1 and is fully mixed by the two revolving and rotating spiral structures 4. After mixing is completed, the discharge valve 5 is opened to discharge the mixed material.

[0033] The conical mixer provided in this embodiment is provided with a material guide member 6 fixedly connected to the barrel 1 on the vertical section 302 of the rotating arm 3, and a first inverted cone-shaped annular gap 7 is formed between the material guide member 6 and the vertical section 302 of the rotating arm 3. A stirring structure 8 fixedly connected to the vertical section 302 of the rotating arm 3 is provided in the first annular gap 7. The upper end of the barrel 1 is provided with a plurality of feeding ports 9 located above the first annular gap 7, so that the powdered raw materials can be pre-mixed while the materials are added to the barrel 1. On the premise of ensuring that the powdered raw materials are fully mixed, the mixing time can be shortened and the mixing efficiency can be improved.

[0034] In some embodiments of the present application, a cylindrical discharge pipe 10 is fixed to the lower end of the material guide 6, the discharge pipe 10 is sleeved on the vertical section 302 of the rotating arm 3 and forms a second annular gap 11 between the vertical section 302, and the stirring structure 8 extends into the second annular gap 11.

[0035] During use, the powdered raw materials gather at the middle position of the lower end of the material guide 6, flow into the second annular gap 11, and fall into the cylinder 1 along the second annular gap 11. When the gathered powdered raw materials fall in the second annular gap 11, the stirring structure 8 stirs the premixed powdered raw materials again to further improve the premixing effect of the powdered raw materials.

[0036] In some embodiments of the present application, the stirring structure 8 includes a plurality of stirring components fixed to a mounting sleeve 801 in an up-and-down arrangement, wherein the stirring components are composed of a plurality of annular stirring blades 802. Specifically, the stirring blades 802 are fixed to the mounting sleeve 801 by welding.

[0037] The mounting sleeve 801 is sleeved and fixed on the vertical section 302 of the rotating arm 3 .

[0038] During use, the vertical section 302 of the rotating arm 3 drives the mounting sleeve 801 to rotate, and the mounting sleeve 801 drives all the stirring blades 802 to rotate simultaneously to stir and mix the powdered raw materials.

[0039] In order to further improve the stirring effect, in some embodiments of the present application, two upper and lower adjacent stirring blades 802 are staggered.

[0040] In some embodiments of the present application, a sealing cover 12 is detachably fixed to the upper end of the feeding port 9, so that the unused feeding port 9 can be closed to prevent dust from leaking out.

[0041] In some embodiments of the present application, a plurality of annular support members 13 are fixed to the outer wall of the cylinder 1. Specifically, the support members 13 are fixedly connected to the bracket to mount the cylinder 1 on the bracket. Furthermore, the annular support members 13 can improve the stability of the cylinder 1 when mounted on the bracket.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
