Problems solved by technology

The existing pouring system for the planetary frame of the wind turbine has poor purification effect on the pouring molten iron, and the flow rate of the molten iron in the pouring system is high, so that the primary slag in the molten iron is directly injected into the planetary frame of the wind turbine In the casting modeling, because the flow rate of the molten iron is high, it is easy to form secondary slag. Because of the above defects, the overall casting of the planetary frame of the wind turbine manufactured by the existing casting system of the planetary frame of the wind turbine The quality is low, the surface quality of the non-processed surface of the web of the wind turbine planet carrier is very difficult to control, and scum is easy to appear on the non-processed surface, which directly leads to the scrapping of the wind turbine planet carrier, making production The cost of the manufacturer is greatly increased and the production efficiency is greatly reduced

Abstract

The invention discloses a pouring system of a wind generator planet carrier, which has the advantages that iron liquor is fully purified, the quality of wind generator planet carrier cast can be effectively improved; the pouring system comprises a filtering part; a filter block (6) is arranged between an upper top trench (5) and a lower top trench I (7), the inlet of the filter block (6) is communicated with the outlet of the upper top trench (5), the outlet of the filter block (6) is communicated with the inlet of the lower top trench I (7); a ring-shaped top trench (9) is provided with a plurality of outlets, outlets of the ring-shaped top trench (9) are in one-to-one correspondence with the lower top trench II (10), filter blocks (6) are arranged between every outlet of the ring-shaped top trench (9) and corresponding lower top trench II (10), the inlet of the filter block (6) is communicated with the outlet of the ring-shaped top trench (9), and the outlet of the filter block (6) is communicated with the inlet of the lower top trench II (10).

Description

technical field [0001] The invention relates to the field of casting, in particular to a pouring system for a planet frame of a wind power generator. Background technique [0002] The wind turbine planetary frame is a key component of the wind turbine. At present, the wind turbine planetary frame is manufactured by casting. The current wind turbine has high requirements on the surface quality of the non-processed surface of the web of the wind turbine planetary frame. , Internationally, no scum is allowed on the non-processed surface of the web of the wind turbine planetary carrier. If there is scum, the wind turbine planetary carrier will be scrapped. The surface quality of the non-processed surface of the web of the wind turbine planet carrier is determined during the casting process, that is to say, once the wind turbine planet carrier is cast, the surface quality of the web of the wind turbine planet carrier The surface quality on the non-processing surface is also dete...
