Efficient energy-saving fan applied to feed, flour and rice system process

Abstract

The invention discloses an efficient energy-saving fan applied to the feed, flour and rice system process. The fan comprises a machine base, wherein a motor is fixedly connected to the upper surface of the machine base, a first rotating shaft is fixedly connected to the outlet end of the motor, a second rotating shaft is fixedly connected to the other end of the first rotating shaft through a connecting assembly, the outer wall of the second rotating shaft is fixedly connected with an impeller, the outer side of the impeller is provided with a machine shell, the upper end of the machine shell is provided with an air outlet, and the back face of the machine shell is fixedly connected with an air inlet ring. The fan adopts an A type transmission structure and is compact in structure and small in size, the fan is equipped with no bearing box and is convenient and easy to maintain and overhaul, a backward impeller motor is stable in current and stable in performance, through the design of a connecting assembly, C type, D type or other transmission modes can be manufactured according to needs, the motor is started to drive the impeller to rotate, airflow enters a machine shell from an air inlet ring and finally flows out of the air outlet, and a stable airflow channel is formed in the machine shell.

Description

technical field [0001] The invention relates to the technical field of fans, and more specifically relates to a high-efficiency and energy-saving fan used in feed, flour and rice system processes. Background technique [0002] The invention with the publication number CN208845388U relates to the technical field of fans, and discloses a high-efficiency energy-saving fan, including a fixing seat, a round opening is opened on the front of the fixing seat, and elastic blocks are fixedly installed on the top and bottom of the round opening. There are two elastic blocks, a driving motor is fixedly installed between the two elastic blocks, and sleeves are fixedly installed on both sides of the circular opening. The high-efficiency energy-saving fan is equipped with a gas dredging fan and a guide fan. When the airflow enters the inside of the air intake box through the first dust-proof net, at this time due to the fluidity of the gas, it will also drive the air above and below the a...

Problems solved by technology

[0003] However, when the above-mentioned conventional national standard fan is selected under this working condition (parameters are flow rate 5200m3 / h, total pressure 3500-4000pa, t=20°C, atmospheric pressure Pa=101325Pa), the selected fan is for example 5-48-5A The power is 11Kw, the speed is 2900rpm, the corresponding parameters are 5590~8320m3 / h, and the total pressure is 4140~3300pa, which does not meet the performance requirements. The speed must be adjusted through the ratio of pulleys or frequency conversion to meet the performance requirements. Not only the power distribution of the motor is relatively large, but also The purchase cost is increased for the C-type pulley drive or frequency conversion. Compared with the A-type direct-coupled fan, it brings the disadvantages of high purchase cost, large floor space, and relatively complicated maintenance.

[0004] Therefore, in the system processes such as dust removal, cooling, drying, ventilation, and powder cleaning in feed, flour, rice, and other systems, it is urgent to develop a fan with a flow rate equivalent to that of a conventional low-pressure fan and a pressure equivalent to a medium-high pressure. High-efficiency and energy-saving fans, and the existing fans cannot be changed according to needs, which is inconvenient to use
