Description

Technical Field

[0001] The utility model relates to the technical field of solar photovoltaic single crystal thermal field, in particular to a single crystal furnace thermal field transportation device. Background Art

[0002] At present, most single crystal furnaces are equipped with only one main heater and one bottom heater. During the crystal pulling process, the bottom heater of this combination is in the off state, and the main heater power is in the on state. In order not to affect the melt, crystal pulling, etc., the heating zone of the heater needs to maintain a certain width. This causes the crucible to be baked over a large area, and the silicon melt violently flushes the crucible over a large area, and finally there is still a large amount of oxygen in the crystal.

[0003] In order to reduce the oxygen content in the crystal, a three-heater single crystal furnace came into being, which mainly includes a main heater, a bottom heater and an auxiliary heater. However, the existing heater transport vehicle can only place the main heater and the bottom heater, and there is no place to place the auxiliary heater, which needs to be placed on a flatbed truck. However, due to the special structure of the auxiliary heater, the heating area will be partially stressed, which can easily cause the heater to deform. In particular, shaking during transportation can more easily aggravate the damage to the heater and reduce its service life. At the same time, when dismantling the furnace, the high-temperature heater cannot be placed on the flatbed truck in reverse. In addition, the hot field parts that need to be cleaned must also be placed on two transport vehicles. It is difficult for a group of furnace dismantling personnel to transport them at one time. It takes a long time to pull them multiple times, and the work efficiency is low. Utility Model Content

[0004] The purpose of the utility model is to solve the problems of inconvenient transportation and low efficiency of existing thermal field parts, and to provide a single crystal furnace thermal field transportation device, which can effectively save transportation time, improve work efficiency, and take into account the transportation of three heaters and other thermal field parts.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A single crystal furnace thermal field transport device comprises a transport vehicle body and a handrail fixed on the transport vehicle body, wherein a high-level rack, a middle-level rack and a low-level rack are respectively arranged on the transport vehicle body, wherein the high-level rack is arranged on a side close to the handrail and has a main heater placement plane arranged thereon, the middle-level rack is arranged close to the front of the transport vehicle body and has an auxiliary heater placement plane arranged thereon, and the low-level rack is arranged below the high-level rack and has a bottom heater placement plane arranged thereon;

[0007] An inclined support rod placement ring is also provided under the low-level rack, a dismantling tool placement table is also provided under the middle-level rack, and a small hot field parts placement plane is also provided on the transport vehicle body. The small hot field parts placement plane is arranged between the support rod placement ring and the dismantling tool placement table to realize the placement and transportation of hot field parts and related tools.

[0008] Furthermore, the transport vehicle body includes a bottom plate, a group of rollers are connected below the bottom plate, a group of stepped columns are fixed on the bottom plate, which are long columns, middle columns and short columns, and handrails are fixed to the upper ends of the long columns.

[0009] Furthermore, a horizontal bar is connected between two adjacent long columns, and the long columns and the horizontal bar constitute the main frame of the high-rise rack. The main heater placement plane on the upper part of the high-rise rack is set as a horizontal T-shaped surface.

[0010] Furthermore, a cross bar is also connected between two adjacent middle columns, and the middle column and the cross bar constitute the main frame of the middle shelf, and the axis of the auxiliary heater placement plane is parallel to the T-shaped surface axis of the main heater placement plane.

[0011] Furthermore, the bottom heater placement plane is arranged on the short columns between the long columns on both sides, and the height of the bottom heater placement plane is greater than half of the height of the long columns.

[0012] Compared with the prior art, the advantages of the technical solution of the utility model are specifically:

[0013] (1) The utility model is designed with a dedicated placement plane for the auxiliary heater, so there is no need to place the auxiliary heater in reverse on a flatbed truck, thus avoiding the problem of the heater structure being deformed due to the placement method, thereby extending the service life of the heater;

[0014] (2) The utility model adds a special placement plane for auxiliary heaters, which makes it easier for hot field dismantling personnel to place heaters. At the same time, it reduces the risk of heater damage caused by shaking during the transportation of heaters by transport vehicles, ensuring the normal use of heaters;

[0015] (3) The utility model can transport the hot field parts that need to be cleaned at one time, saving transportation time. In addition, a three-heater transport vehicle can save about 1.2 square meters of storage area compared with the conventional two-heater transport vehicle. For idle places in the hot field and places for on-site dismantling and cleaning, the area that can be saved is more obvious. BRIEF DESCRIPTION OF THE DRAWINGS
