[0028] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase that an embodiment in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of other embodiments. It is explicitly contemplated that embodiments described herein can be combined with each other.

[0029] Embodiments of the utility model provide a kind of silicon rod cleaning degumming device, as shown in Figures 1-7 The silicon rod cleaning degumming device includes:

[0030] The first section includes a spraying assembly 100 and a first conveying mechanism 310. The first conveying mechanism 310 pulls the silicon rod 400 to move along the axial direction of the silicon rod 400. The spraying assembly 100 is arranged above the first conveying mechanism 310 and sprays cleaning liquid on the silicon rod 400 passing through the spraying assembly 100.

[0031] A second section is arranged at the rear end of the first section, and the second section comprises a cleaning assembly 200 and a second conveying mechanism 320 which is identical in structure to the first conveying mechanism 310. The cleaning assembly 200 comprises a support frame 210, a loading plate 220 and high-pressure nozzles 230. The loading plate 220 is arranged on the support frame 210, and the loading plate 220 is provided with a cleaning area. The high-pressure nozzles 230 are distributed in the cleaning area. The silicon rod 400 passes through the cleaning assembly 200 under the action of the second conveying mechanism 320.

[0032] In this embodiment, the first section mainly sprays cleaning liquid on the silicon rod 400 to soften and separate the glue on the surface of the silicon rod 400, thereby achieving preliminary separation and reducing the difficulty of subsequent processing. The second section sprays high-pressure water from the high-pressure nozzles 230 to remove the residual materials that are not easy to separate from the surface of the silicon rod 400 by high-pressure impact, thereby improving the cleaning effect of the residual materials on the silicon rod 400. The use of the two-section series connection can quickly separate part of the glue that is not easy to fall off by using the impact method after the residual materials are sprayed and soaked, thereby improving the cleaning effect.

[0033] As a preferred embodiment in this embodiment, the number of the spraying assemblies 100 is several, and the spraying assemblies 100 are arrayed on the first conveying mechanism 310. The spraying assembly 100 comprises a gantry 110 and a spraying pipe 120. The gantry 110 is arranged on the first conveying mechanism 310. The spraying pipe 120 is connected to the gantry 110 at both ends. The spraying pipe 120 is horizontally arranged on the first conveying mechanism 310. The cleaning liquid sprayed by the spraying pipe 120 drops onto the surface of the silicon rod 400 passing through the gantry 110.

[0034] In this embodiment, different spraying pipes 120 are filled with cleaning liquid of different compositions. The spraying pipe 120 sprays the cleaning liquid to enable the cleaning liquid to fully contact the silicon rod 400. The silicon rod 400 moves along the axial direction of the silicon rod 400 by the first conveying mechanism 310. After the cleaning liquid drops onto the outer surface of the silicon rod 400, the cleaning liquid also slides along the outer surface, thereby maximizing the coverage of the outer surface of the silicon rod 400.

[0035] As a preferred embodiment in the embodiment, the cleaning area is in the shape of an arc structure, and the high-pressure nozzles 230 are arranged in an annular array in the cleaning area, wherein a plurality of groups of high-pressure nozzles 230 form an annular structure on the outer surface of the silicon rod 400, and the impact dead angle on the outer surface of the silicon rod 400 is reduced by the coordinated impact of the plurality of groups of high-pressure nozzles 230. Meanwhile, the number of the cleaning assemblies 200 is not less than three, and the orientations of the high-pressure nozzles 230 on different cleaning assemblies 200 are arranged in a staggered manner. In this way, the landing points of the high-pressure nozzles 230 on different cleaning assemblies 200 on the outer surface of the silicon rod 400 are different, which can further reduce the impact dead angle, avoid the situation that the arc structure cannot achieve full coverage, and improve the treatment effect of the residues.

[0036] As a preferred embodiment in the embodiment, the first conveying mechanism 310 and the second conveying mechanism 320 adopt prior art devices. The first conveying mechanism 310 comprises a bearing table 311 and a plurality of groups of roller mechanisms. The roller mechanism comprises a support seat 312, a rotating shaft 313, and a rotating roller 314. The rotating roller 314 is arranged on the rotating shaft 313. The rotating shaft 313 extends into the support seat 312 at both ends and is assembled on the support seat 312 through bearings. The surface of the rotating roller 314 is in the shape of an inclined plane.

[0037] One end of the rotating shaft 313 is provided with a transmission mechanism. The transmission mechanism comprises a driving wheel 3151, a driven wheel 3152, and a transmission shaft 3153. The driving wheel 3151 is arranged at one end of the rotating shaft 313. The driven wheel 3152 is in meshing connection with the driving wheel 3151. The transmission shaft 3153 is in meshing connection with the driven wheel 3152.

[0038] One end of the transmission shaft 3153 is provided with a driving gear, and the other end is provided with two groups of chain wheels. The transmission shaft 3153 obtains power through chain transmission. The two groups of chain wheels are respectively connected with other transmission shafts 3153 through chains to realize power transmission. The structure herein refers to the prior art chain transmission technology and will not be described in detail.

[0039] In a further preferred embodiment of the utility model, the first conveying mechanism 310 and the second conveying mechanism 320 are both provided with water accumulation grooves 316. Taking the first conveying mechanism 310 as an example, the water accumulation groove 316 is arranged on the bearing table 311 and is located below the roller mechanism to collect and recycle the water flow in the cleaning process.
