Description

Gas conveying equipment with inner rotor driving outer rotor Technical Field The utility model belongs to the technical field of gas conveying equipment, and particularly relates to gas conveying equipment with an inner rotor driving an outer rotor. Background The main parts of gas conveying equipment, such as sliding vane compressor, consist of three parts, including machine body, rotor and sliding vane. The rotor of sliding vane compressor is eccentrically arranged in cylinder, and has several longitudinal grooves with sliding vanes capable of sliding freely along radial direction. Because the rotor is arranged eccentrically in the cylinder, a crescent space is formed between the inner wall of the cylinder and the outer surface of the rotor. When the rotor rotates, the sliding vane is thrown out of the groove under the action of centrifugal force, the end of the sliding vane is clung to the inner circular wall surface of the machine body, and the crescent space is divided into a plurality of fan-shaped cells, namely primitive volumes, by the sliding vane. Within one revolution of the rotor, the volume of each element gradually increases from a minimum value to a maximum value, and gradually decreases from the maximum value to the minimum value. With the continuous rotation of the rotor, the elementary volumes vary cyclically following the above-mentioned law. The main disadvantage of the traditional sliding vane compressor is that the mechanical friction between the sliding vane and the rotor and the cylinder are serious, and larger abrasion and energy loss are generated, especially when the rotating speed is higher. The rotating speed is very low, and the sliding vane is not easy to throw out or cling to the cylinder, so that the compressor cannot work normally. In order to reduce friction between the slide and the cylinder, pan Shulin et al in the literature "analysis of structure of rotary-cylinder hinged slide compressor" proposed a slide compressor of a new structure, which adds a rotary cylinder in the cylinder and hinges the slide outer end with the rotary cylinder, the rotary cylinder is driven by the slide (the slide inner end is still set in the slide groove of the rotor). Besides the hinge groove, the rotary cylinder is also provided with an air suction notch and an air discharge notch, the air discharge side cylinder cover is provided with an arc-shaped air outlet groove, a plurality of air discharge holes are formed in the arc-shaped air outlet groove, the air suction side cylinder cover is provided with an annular air suction groove, and the outer peripheral side wall of the annular air suction groove is provided with air suction holes. However, the scheme in the above document has the following defects that 1, the cylinder cover at the exhaust side is provided with a circular arc-shaped air outlet groove, only when the exhaust notch of the rotary cylinder is communicated with the circular arc-shaped air outlet groove, the problem of cylinder explosion easily occurs in some gas-liquid mixed compression occasions, 2, the two cylinder covers are in a T shape, the structure is unreasonable, 3, the related structure of the exhaust valve is not described, and 4, the sealing structures among the rotary cylinder, the rotor and the cylinder covers are not described. Other prior art such as CN 101498306B-rotary compressors are also relatively complex in their exhaust structure. At the same time, the aforementioned disadvantages also occur with other gas delivery devices such as vacuum pumps. Disclosure of Invention Aiming at the defects of the air inlet or exhaust structure of the existing gas conveying equipment with the sliding vane and the rotary cylinder in rotary connection, the utility model provides the gas conveying equipment with the inner rotor driving the outer rotor, and improves the air inlet and exhaust structure of the gas conveying equipment, so that the gas conveying equipment can be applied to more occasions such as gas-liquid mixing and/or higher compression ratio. In order to achieve the purpose, the utility model adopts the following technical scheme that the gas conveying equipment of the inner rotor driving the outer rotor comprises: A base; the air inlet end cover is fixed on the base; The air outlet end cover is fixed on the base; An inner rotor positioned between the air inlet end cover and the air outlet end cover, a chute is formed; A sliding sheet; an outer rotor having an axially-through accommodation chamber; Wherein, the inner rotor is eccentrically and tangentially arranged in the accommodating cavity of the outer rotor; the outer end of the sliding vane is connected to the outer rotor in a swinging way, and the inner end of the sliding vane is connected to the sliding groove in a sliding way; an air inlet channel communicated with the accommodating cavity is formed between the air inlet end cover and the outer rotor; And an air outlet channel communicated with the ac
