Description

Micro-oil screw air compressor with auxiliary preheating function Technical Field The utility model relates to the technical field of air compressors, in particular to an auxiliary preheating micro-oil screw air compressor. Background The micro-oil screw air compressor is widely applied to a plurality of fields of industrial production, engineering machinery, energy sources, electronics and the like, is used as important compressed gas equipment, and can provide a stable compressed air source. The working principle of the micro-oil screw air compressor is that air is driven to be compressed and heated through screw rotation, and meanwhile, a small amount of lubricating oil is used to ensure the normal operation of a screw assembly. Due to the characteristics of compact structure, high efficiency, stable operation and the like, the micro-oil screw air compressor becomes the first choice equipment in many industrial applications. However, the problems of low efficiency and high energy consumption are often faced when the air compressor is started and operated under low load, and particularly in a low-temperature environment, the problems of difficult starting and unstable operation of the air compressor are more remarkable. The preheating requirement on the intake air flow of the air compressor in the starting process is high, and particularly in a cold environment, the traditional preheating device is usually insufficiently heated, so that the air compressor is difficult to start, and even cannot start. Secondly, the installation space and the structural design of the existing heating device are often complex, and the manufacturing cost and the maintenance difficulty of the air compressor are increased. In view of the above, in order to overcome the technical problems, the utility model designs a micro-oil screw air compressor for assisting in preheating. Disclosure of Invention The utility model aims to realize the technical purposes of optimizing the flow of air flow in an air inlet channel through the design of a diversion layer and the configuration of a blower and ensuring the efficient transfer of heat, thereby solving the technical problems of difficult starting and unstable working of an air compressor under low-load and high-load working conditions. In order to achieve the technical purpose, the utility model provides the following technical scheme: The micro-oil screw air compressor for auxiliary preheating comprises an air compressor main body, an air inlet channel and a preheating component, wherein the air inlet channel for air inlet is arranged in the middle of the air compressor main body, and the preheating component is arranged on the outer wall of the air inlet channel. The preheating component comprises a blower for providing air flow, a heating layer for heating the air flow, an air inlet for sucking external air flow and an air outlet for exhausting the air flow to the main body of the air compressor, wherein the heating layer ensures that the air flow reaches a required temperature before entering the air compressor, improves the working environment of the air compressor when the air compressor is started, and reduces the starting load. Furthermore, a plurality of the blower arrays are arranged on the outer wall of the heating layer, and the plurality of the blower arrays can provide stronger airflow power to ensure that the airflow is uniformly distributed in the whole heating layer and is efficiently heated. The phenomenon of uneven air flow can be avoided by the cooperative work of the plurality of blowers, and the high efficiency and the stability of air heating are ensured. The exhaust port is aligned with the middle part of the air compressor main body, and the exhaust direction of the exhaust port is parallel to the axial direction of the air inlet channel, so that the heated air flow can smoothly flow into the air compressor main body, and the phenomenon of resistance or instability of air flow can not occur. The heating layer comprises an outer diversion shell, a middle diversion cavity and an inner heating inner shell, wherein the outer diversion shell is arranged on the outer wall of the air inlet channel through a support frame on the inner side, the outer diversion shell is used as an outer layer member, effective guiding and distributing of air flow are ensured by the outer diversion shell, the air flow can uniformly flow through the surface of the inner heating shell, the protection effect is achieved, and the direct influence of the external environment on the inner heating shell is avoided. Further, the heating inner shell is closely attached to the air inlet channel and directly heats air in the air inlet channel. Because the heating inner shell is in close contact with the air inlet channel, heat can be rapidly transferred to the air inlet flow, and the air flow is ensured to reach the required preheating temperature before entering the air compressor, so that the sta
