Title:
HIGH-EFFICIENCY ENERGY-SAVING DIRECT-DRIVE SAND MAKING MACHINE
Document Type and Number:
WIPO Patent Application WO/2016/015601
Kind Code:
A1
Abstract:
Disclosed is a high-efficiency energy-saving direct-drive sand making machine, comprising a sand making machine shell (1), an impeller (2), a motor (3), a motor bracket (5), a motor sealing pressing plate (6) and a peripheral guard plate, wherein the impeller (2) is located in the sand making machine shell (1), and is directly mounted on a shaft of the motor (3); the motor (3) is mounted in the motor bracket (5); and the peripheral guard plate is mounted between the sand making machine shell (1) and the impeller (2). The motor bracket (5) comprises an outer shell (51), an upper end plate (52), a lower end plate (53), an inner shell (54), an upper support plate (55), a lower support plate (56), a guide plate (57) and sealing plates (58), wherein the two sealing plates (58) on the left and on the right and the guide plate (57) are combined with the inner shell (54), the upper support plate (55), the lower support plate (56) and the outer shell (51) to form a closed space for sealing the motor (3). By adopting a structure where the impeller and the motor are coaxially directly coupled and directly driven, compared with an existing non-coaxial indirect-drive sand making machine, the present invention has the advantages of high transmission efficiency, long service life of the motor, etc.
