Description

Roots blower with adjustable air inlet and outlet pipe angles

Technical Field

The utility model relates to a roots blower equipment technical field specifically is a roots blower of adjustable business turn over tuber pipe angle.

Background

The Roots blower is also called Roots blower, and belongs to a volume rotary blower, a rotary compressor for compressing and conveying gas by utilizing two blades or three blade rotors to operate in a cylinder is simple in structure and convenient to manufacture, is suitable for gas conveying and pressurization in low-pressure occasions, and can also be used for a vacuum pump. The air outlet of the blower at present is uniformly designed towards the same direction as that of the factory, or is designed towards a certain direction according to the requirement of a customer, once the blower is machined, produced and molded, the air outlet of the blower cannot be changed, so that a great deal of inconvenience is caused to the use of a user, the position of the air inlet and the air outlet are required to be changed after the blower is installed, and in order to avoid the occurrence of the condition, the Roots blower with the rotatable air inlet and outlet pipe is required.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model provides a roots blower of adjustable business turn over tuber pipe angle has solved business turn over tuber pipe can not pivoted problem.

The utility model discloses a realize through following technical scheme:

the Roots blower with the adjustable air inlet and outlet pipe angles comprises a motor and a fan blade disc, wherein the bottom end of the motor is connected with an upper casing of the blower, a plurality of rhombic columns are uniformly and fixedly connected to the bottom surface of the upper casing of the blower, a lower casing of the other end of the rhombic column is fixedly connected with a lower casing of the blower, annular clamping grooves are symmetrically formed in the lower side of the upper casing of the blower and the upper side of the lower casing of the blower, annular lining plates are placed in the annular clamping grooves, an air inlet pipe is connected to one side of each annular lining plate in a penetrating manner, an air outlet pipe is connected to the positions, opposite to the air inlet pipe, of each.

Preferably, the output shaft of the motor penetrates through the upper shell of the blower and is connected with the fan blade disc.

Preferably, silencers are installed at the pipe openings of the air inlet pipe and the air outlet pipe.

Preferably, a filter screen is installed on the upper portion of the air inlet pipe.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model divides the Roots blower into an upper shell and a lower shell, the middle parts of the Roots blower are fixedly connected through the spaced prism columns, and then the Roots blower is sealed through the annular clamping groove and the annular lining plate, so that the angles of the air inlet pipe and the air outlet pipe can be realized by rotating the annular lining plate; the sealing gasket can ensure that air leakage cannot occur when the annular lining plate is rotated.
