Description

Technical Field

[0001] This utility model relates to the field of barrel protection technology, specifically to a top protection device for a quartz barrel. Background Technology

[0002] The global photovoltaic industry is currently experiencing rapid growth, and photovoltaic power generation is poised to become a crucial pillar of the global energy sector. China now boasts over a thousand photovoltaic companies. However, with the industry's rise, competition among these companies is intensifying, prompting continuous innovation and reform, with cost reduction and efficiency improvement being key strategies.

[0003] In existing technology, when the material preparation worker fills the material bag, a notch is cut open, and the material is poured directly into the material cylinder, which then guides the material block into the single crystal furnace. However, this method causes the material block in the bag to collide with the top of the material cylinder, which can easily damage the cylinder and increase production costs. Therefore, it needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide a protective device for the top of a quartz barrel, which can protect the top of the barrel from being damaged by material blocks, extend the service life of the barrel, and thus achieve the goal of reducing costs and increasing efficiency.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A quartz barrel top protection device is provided, including a barrel, which is a hollow tubular structure, and a feeding hopper. The top of the feeding hopper is an inverted semi-conical plate structure, and the bottom of the feeding hopper is an arc plate structure. The feeding hopper is detachably installed on the top of the barrel.

[0007] Furthermore, there is a pair of feeding hoppers, which are symmetrically arranged on both sides of the silicon tube at the top of the cylinder.

[0008] Furthermore, a slot is provided at the bottom of the feeding hopper. The slot has an arc-shaped structure and is inserted into the top side wall of the material cylinder.

[0009] Furthermore, the inner wall of the slot has a long lower edge and a short lower edge. The bottom of the long lower edge is lower than the bottom of the short lower edge. The short lower edge abuts against the inner wall of the material cylinder, and the long lower edge abuts against the outer edge of the material cylinder.

[0010] Furthermore, a groove is provided on the top wall of the slot, and an annular protrusion is fixedly connected to the top of the material cylinder, with the annular protrusion interlocking with the inner wall of the groove.

[0011] Furthermore, the feeding hopper is made of polytetrafluoroethylene.

[0012] The beneficial effects of this utility model are as follows: By setting up a feeding hopper, this utility model adds a detachable feeding hopper to the top of the material cylinder during the filling process, based on the original material cylinder structure. This not only protects the top of the material cylinder from being damaged by the material blocks and extends the service life of the material cylinder, but also prevents the silicon material from spilling and ensures that the silicon material slides smoothly, thereby improving the feeding efficiency, achieving the goal of reducing costs and increasing efficiency, and thus enhancing the company's competitiveness.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0022] Reference Figures 1 to 4 The quartz barrel 1 top protection device shown includes a barrel 1, which is a hollow tubular structure, and a feeding hopper 2. The top of the feeding hopper 2 is an inverted semi-conical plate structure, and the bottom of the feeding hopper 2 is an arc plate structure. The feeding hopper 2 is detachably installed on the top of the barrel 1.

[0023] During filling, first insert the feeding hopper 2 into the top of the material cylinder 1. Then, cut a notch in the material bag and raise it to the top of the material cylinder 1. Next, align the opening of the material bag with and press it against the top opening of the feeding hopper 2. Flip the material bag to pour the silicon material into the material cylinder 1 along the feeding hopper 2. This simple operation protects the edge of the top opening of the material cylinder 1 by using the feeding hopper 2, effectively preventing the silicon material from being bumped and extending the service life of the material cylinder 1. Furthermore, the feeding hopper 2 is detachable for easy replacement. The top structure of the feeding hopper 2 extends outward at an angle, which increases the opening area at the top of the material cylinder 1 and prevents the silicon material from spilling. The bottom structure of the feeding hopper 2 fits snugly against the inner wall of the material cylinder 1, ensuring that the silicon material slides smoothly and improving the filling efficiency.

[0024] like Figures 1 to 3 As shown, there is a pair of feeding hoppers 2, which are symmetrically arranged on both sides of the silicon tube 3 at the top of the material cylinder 1. The symmetrical design of the two feeding hoppers 2 facilitates feeding from the material cylinder 1 and avoids mutual contact with the silicon tube 3, thereby further improving the convenience of feeding.

[0025] like Figure 3 and Figure 4 As shown, the bottom of the feeding hopper 2 is provided with a slot 20, which is an arc-shaped structure and is inserted into the top side wall of the material cylinder 1.

[0026] The inner wall of the slot 20 has a long lower edge 200 and a short lower edge 201. The bottom of the long lower edge 200 is lower than the bottom of the short lower edge 201. The short lower edge 201 abuts against the inner wall of the material cylinder 1, and the long lower edge 201 abuts against the outer periphery of the material cylinder 1.

[0027] The top wall of the slot 20 has a groove 21, and the top of the material cylinder 1 is fixedly connected to an annular protrusion 10, which is inserted into the inner wall of the groove 21.

[0028] When installing the feeding hopper 2, simply align the bottom slot 20 with the top side wall of the material cylinder 1 and insert it to quickly complete the installation. This ensures the annular protrusion 10 is inserted into the groove 21, preventing the feeding hopper 2 from sliding. During feeding, the material bag presses against the feeding hopper 2, and under gravity, the feeding hopper will flip outwards. At this time, the long lower edge 200 abuts against the outer wall of the material cylinder 1, providing support and preventing the feeding hopper 2 from falling off. When removing the feeding hopper 2, if it becomes stuck or adhered, push the feeding hopper 2 to flip it inwards and shake it. The short lower edge 201 allows the feeding hopper 2 to flip and move inwards towards the material cylinder 1, gradually loosening it upwards, thus facilitating removal and replacement.

[0029] like Figures 1 to 4As shown, the feeding hopper 2 is made of polytetrafluoroethylene (PTFE). PTFE is characterized by high temperature resistance, corrosion resistance, and a low coefficient of friction. The feeding hopper 2, made of PTFE, can adapt to the high-temperature working environment of the single crystal furnace and reduce wear and tear from friction with the silicon material, further achieving the goal of cooling and increasing efficiency.

[0030] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
