Abstract
The utility model discloses a diffusion furnace, which comprises a furnace body, a tray and a hook, wherein the furnace body is provided with a furnace mouth; the tray is arranged below the furnace mouth, and is used for receiving metaphosphoric acid flowing out of the furnace mouth; and the hook can extend into the furnace body, and is used for clearing the metaphosphoric acid produced in the furnace body. In the diffusion furnace, metaphosphoric acid flowing out of the furnace mouth is received by the tray, and metaphosphoric acid produced in the furnace body is cleared by the hook, so that the inside of the diffusion furnace is kept clean, and metaphosphoric acid is prevented from corroding metal components in the diffusion furnace.
Description
[technical field]
The utility model relates to area of solar cell, relates in particular to a kind of diffusion furnace that is used for solar cell.
[background technology]
The diffusion furnace that is used for the stopped pipe solar cell is in secular use, can produce a large amount of metaphosphoric acids in diffusion furnace fire door and stove owing to contact with outside air and high temperature, moist environment, and the metaphosphoric acid of these generations can corrode the metal parts in the diffusion furnace.
[utility model content]
Based on this, be necessary to provide a kind of diffusion furnace that can collect and remove the metaphosphoric acid in diffusion furnace fire door and the stove.
A kind of diffusion furnace comprises body of heater with fire door, is arranged on described fire door below and is used to access the pallet of the effusive metaphosphoric acid of described fire door and can stretch in the described body of heater and be used to remove the hook of the metaphosphoric acid that produces in the described body of heater.
Preferably, described pallet is and described fire door quartzy pallet of the same size.
Preferably, described pallet thickness is 2mm.
Preferably, described hook comprises quartz rod and is fixed on the quartz plate of described quartz rod one end, the arcuate structure that described quartz plate and described body of heater contact position are complementary for the inner chamber with described body of heater.
Preferably, also comprise the offgas duct that is used to discharge waste gas in the described body of heater, described offgas duct one end links to each other with the external world, and the other end is arranged on the inner chamber of described body of heater.
This diffusion furnace accesses the effusive metaphosphoric acid of fire door by pallet, removes the metaphosphoric acid that produces in the body of heater by hook, thereby keeps the cleaning in the diffusion furnace, avoids the metal parts in the metaphosphoric acid corrosion diffusion furnace.

[embodiment]
Below in conjunction with drawings and Examples diffusion furnace is further described.
As shown in Figure 1, diffusion furnace comprises body of heater 10, pallet 30, hook 40 and offgas duct 50.Body of heater 10 has inner chamber 12, and an end is provided with fire door 20.Pallet 30 is arranged on fire door 20 belows, is used to access fire door 20 effusive metaphosphoric acids.One end of hook 40 can stretch into the inner chamber 12 of body of heater 10, is used to remove the metaphosphoric acid that produces in the body of heater 10.One end 52 of offgas duct 50 links to each other with the external world, and the other end 54 is arranged on body of heater 10 inner chambers 12, is used to discharge waste gas in the body of heater 10.
As shown in Figures 2 and 3, pallet 30 is and fire door 20 quartzy pallets of the same size, is square box shape, and specification is 250mm*200mm*40mm, and thickness is 2mm.
As shown in Figure 4 and Figure 5, hook 40 comprises quartz rod 42 and is fixed on the quartz plate 44 of quartz rod 42 1 ends that quartz plate 44 is arranged on body of heater 10 inner chambers 12.Quartz plate 44 is the arcuate structure 46 that is complementary with body of heater 10 inner chambers 12 with body of heater 10 contact positions.
Above-mentioned diffusion furnace accesses fire door 20 effusive metaphosphoric acids by pallet 30, removes the metaphosphoric acid that produces in the body of heater 10 by hook 40, thereby keeps the cleaning in the diffusion furnace, avoids the metal parts in the metaphosphoric acid corrosion diffusion furnace.
The above embodiment has only expressed one or more embodiments of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
