Abstract
The utility model discloses a cylinder body structure of rotary blower. The inner wall of the cylinder body is provided with at least two air suction grooves (3) along the shaft direction. All air suction grooves (3) are connected with a suction port (1) by an air suction channel (5). A corresponding exhaust groove (4) is arranged on the cross section of the inner wall of the cylinder body on which an air suction groove is positoned. All exhaust grooves (4) are communicated with an exhaust port (2) through an exhaust passage (6). After the above technical proposal is adopted, the width of each air suction groove and each exhaust groove is similar to the original width of each air suction groove and each exhaust groove in the cylinder body through lengthening the length of the cylinder body, so the grinding processing of the inner wall can not be influenced and the manufacture is convenient. Each air suction groove and each exhaust groove are respectively communicated with the suction port and the exhaust port through the air suction channel and the exhaust passage. The air suction and air exhaust are uniform, so the noise is reduced, the energy consumption is saved, and the abrasion of the sliding blade is uniform at the same time. A plurality of air suction grooves and exhaust grooves are arranged in the cylinder body, so the air input and the air exhausting quantity is enlarged and the air output quantity of the blower is improved.
Description
Technical field
The utility model relates to a kind of housing structure of rotary blower.
Background technique
The rotary blower cylinder body is provided with intakeport and relief opening at present, and inboard wall of cylinder block is provided with a pair of air-breathing groove and air vent, and air quantity is all at 10m
3Below/the min, strengthen air quantity, just must strengthen the diameter of cylinder body, owing to be subjected to the restriction of slide plate linear velocity, diameter of cylinder can not strengthen arbitrarily, the length of the cylinder body that therefore can only extend.But increase along with air quantity, the suction and discharge bore must increase simultaneously, air-breathing groove and air vent on the corresponding inboard wall of cylinder block will be widened, this brings a lot of inconvenience for the mill processing of inwall, while, the two ends of long air-breathing groove and air vent were air-breathing inhomogeneous, increased noise along with air-breathing groove and air vent widens, the wearing and tearing of slide plate are also inhomogeneous, influence the working life of complete machine.
Summary of the invention
The utility model provides a kind of housing structure of rotary blower for solving the problems of the technologies described above, and it can improve the air output of blower fan greatly, and energy-saving and noise-reducing.
The technical solution of the utility model is as follows: the housing structure of rotary blower, cylinder body is provided with intakeport and relief opening, air-breathing groove on the inboard wall of cylinder block is communicated with intakeport, air vent is communicated with relief opening, inboard wall of cylinder block is provided with two air-breathing grooves vertically at least, all air-breathing grooves are communicated with intakeport by air intake passage, and the cross section of the inboard wall of cylinder block at each air-breathing groove place is provided with corresponding air vent, and all air vents are connected with relief opening by the exhaust passage.
After adopting technique scheme, by the length of lengthening cylinder body, close in the width of each air-breathing groove and air vent and the original cylinder body, the mill that does not influence inwall is processed, and is easy to make.Each air-breathing groove is communicated with intakeport by air intake passage, and each air vent is communicated with relief opening by the exhaust passage, and air-breathing exhaust is even, has both reduced noise, has saved energy consumption again, and slide plate wearing and tearing simultaneously evenly.Be provided with a plurality of air-breathing grooves and air vent in the cylinder body, strengthened air output and exhaust air rate, improved the air output of blower fan greatly.

Embodiment
With reference to the accompanying drawings, the housing structure of the utility model rotary blower, it is provided with intakeport 1 and relief opening 2, and inboard wall of cylinder block is provided with 3, three air inlet ducts of three air inlet ducts 3 vertically and is communicated with intakeport 1 by air intake passage 5.The cross section of the inboard wall of cylinder block at each air inlet duct 3 place is provided with 4, three air vents 4 of corresponding air vent and communicates with relief opening 2 by exhaust passage 6.Behind the cylinder body length lengthening, need only the length of corresponding elongated rotor and slide plate, just can improve the air output of blower fan.
The utility model does not terminate in above-mentioned mode of execution, as long as inwall is provided with a plurality of air inlet ducts and air vent all in protection domain of the present utility model.
