Fig. 2 is a schematic top view of an embodiment of the present invention.
Detailed Description
The invention is further described below with reference to the drawings and the detailed description.
Examples
Referring to fig. 1-2, the energy-saving screw air compressor according to the embodiment comprises a box body 1, an air filter assembly 2, a main motor 3, a screw air compressor host 4, an oil filter assembly 5 and an oil-gas barrel 6 which are arranged in the inner cavity of the box body 1, and further comprises a control system for controlling the operation of the whole unit and a cooling system for cooling the whole unit. The cooling system comprises an air inlet mechanism, a plate-fin heat exchanger 7 assembled on the box body 1 and an air exhaust mechanism, wherein:
The air inlet mechanism comprises an air inlet fan blade assembled on a main motor shaft and an air inlet 8 arranged on the box body 1 and corresponding to the air inlet fan blade. The air inlet fan blade comprises a fan blade sleeve 15 and 9 inclined plate type blades 16 which are uniformly arranged along the circumferential direction of the fan blade sleeve 15. The box body 1 at the air inlet 8 is provided with a grating plate.
The exhaust mechanism comprises an exhaust outlet 9 formed in the box body 1, a valve plate 10 assembled at the exhaust outlet 9 and a valve plate driving device for driving the valve plate 10 to open and close. The valve plate 10 is matched with the air outlet 9 in size and is assembled on the side wall of the air outlet 9 through a rotating shaft 11. The valve plate driving device adopts an air cylinder 12, the bottom of the cylinder body of the air cylinder 12 is hinged on an air cylinder seat 14 fixedly assembled on the box body 1 through a rotary supporting shaft 13, the end part of a telescopic rod of the air cylinder 12 is connected with a rotating shaft 11, and an electromagnetic valve of the air cylinder 12 is connected and controlled by a control system. An exhaust net cover is arranged at the exhaust outlet 9.
The air inlet fan blade in this embodiment is installed on the main motor shaft and at the position of the cooling fan blade of the original main motor (i.e. the air inlet fan blade is used to replace the cooling fan blade of the original main motor), and after the equipment is started, the main motor shaft rotates to drive the air inlet fan blade to rotate, so that cold air is sucked into the box 1. The cooling fan blade of the original main motor is replaced by the air inlet fan blade, so that the main motor 3 is cooled, and the whole unit is cooled.
The air filter assembly 2, the main motor 3, the screw air compressor main unit 4, the oil filter assembly 5, the oil gas barrel 6 and the plate-fin heat exchanger 7 all adopt the prior art, and the specific structure, the working principle and the assembly mode among all the components are not repeated here.
As other embodiments of the present invention, the valve plate driving device may also use an oil cylinder or an electric push rod.
The working principle of the invention is briefly described as follows:
The highest temperature and the lowest temperature of the unit are set according to the unit requirement, the unit is started (at the moment, the valve plate 10 is in an open state), the main motor shaft rotates to drive the air inlet fan blade to rotate, cold air is sucked into the box body 1 from the air inlet 8 and is discharged from the air outlet 9 without resistance (most of cold air can be discharged from the air outlet 9 without resistance due to resistance when the plate-fin heat exchanger 7 discharges air). When the temperature in the unit rises to the highest set temperature, the control system controls the cylinder 12 to act to drive the rotating shaft 11 to rotate to close the valve plate 10, at the moment, cold air entering the box body 1 from the air inlet 8 is discharged from the plate-fin heat exchanger 7, and in the process, the whole unit is cooled down. When the temperature in the unit is reduced to the lowest set temperature, the control system controls the cylinder 12 to act, drives the rotating shaft 11 to rotate to open the valve plate 10, cold air entering the box body 1 from the air inlet 8 is discharged from the air outlet 9 without resistance, and the plate-fin heat exchanger 7 does not cool the unit any more. Control of the unit temperature is thus achieved by controlling the opening and closing of the valve plate 10.
The invention utilizes the main motor to drive the air inlet fan blade to rotate to suck cold air into the box body, thereby cooling the unit without additionally arranging a power frequency cooling fan, reducing the production cost and the maintenance cost of equipment, reducing the electricity consumption and the use cost of the equipment, and in addition, the box body is provided with the air outlet and the rotatable valve plate at the air outlet, thereby realizing the control of the temperature of the unit by controlling the opening and closing of the valve plate.
The foregoing is only the embodiments of the present invention, and the patent scope of the invention is not limited thereto, but is also within the scope of the invention, as long as the equivalent structures described in the specification and drawings of the present invention are used directly or indirectly in other related technical fields.
