Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary devices for the production of precipitated white carbon black, in particular to an exhaust collection cover device for a screw air compressor. Technical Background

[0002] The production process of precipitated silica is precipitation reaction, aging, filtration, washing, pulping and spray drying. In the production process of silica, screw air compressors provide the required compressed air power for various equipment and processes. For example, silica powder needs to be transported, ground and packaged with compressed air. In this process, screw air compressors play an important role and become key equipment for providing compressed air. In the operation of existing screw air compressors, it is common that a large amount of heat is generated and cannot be discharged in time, resulting in excessive temperature in the air compressor room. Excessive intake air temperature will lead to adverse consequences such as decreased performance of the air compressor equipment and increased failure rate. Although the air compressor room is equipped with ventilation facilities, the cooling effect is poor. Summary of the invention

[0003] The utility model aims to provide a screw air compressor exhaust collection cover device which has a simple and compact structure, low manufacturing and maintenance costs, and reliable use, so as to solve the problem of high failure rate of the air compressor caused by excessive temperature in the machine room due to the failure of the screw air compressor to discharge heat in time in the prior art.

[0011] The specific implementation of the screw air compressor exhaust collection cover device of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0012] Figure 1 As shown, the utility model is a screw air compressor exhaust collection cover device comprising an air intake filter 1, a screw air compressor 2, an oil-gas separator 3, an air cooler 4, a fan 5, an oil filter 6, an exhaust collection cover 7, and an axial flow fan 8; the outlet of the air intake filter 1 is connected to the inlet of the screw air compressor 2; the outlet of the screw air compressor 2 is connected to the inlet of the oil-gas separator 3; the top air outlet and the lower oil outlet of the oil-gas separator 3 are respectively connected to the corresponding inlets of the air cooler 4, the air outlet of the air cooler 4 is connected to the use point, and the oil outlet of the air cooler 4 is connected to the screw air compressor 2 after connecting to the oil filter 6; the fan 5 is arranged directly below the air cooler 4; a frustum-shaped exhaust collection cover 7 with a small upper opening and a large lower opening is arranged directly above the air cooler 4, the lower opening of which covers the air cooler 4, and the upper opening is connected to the outdoor exhaust pipe for discharge after being connected to the axial flow fan 8 through a pipeline, and the exhaust collection cover 7 is fixedly installed on the hood of the air compressor.

[0013] The following is a detailed description of the working process of the exhaust collection cover device of a screw air compressor of the utility model in conjunction with the accompanying drawings:

[0014] The air treatment process of the screw air compressor system, including air intake filtration, compression, cooling and lubricating oil circulation, ensures the quality of compressed air and the stable operation of the system.

[0015] Inlet filter 1: The air first passes through the air intake filter 1. The function of this filter is to remove dust and impurities in the air to protect the interior of the screw air compressor 2 from pollution.

[0016] Screw air compressor 2: The filtered air enters screw air compressor 2, where the air is compressed and mixed with the injected cooling lubricating oil during the compression process; the lubricating oil is not only used for cooling, but also for reducing wear during the compression process.

[0017] Oil-gas separator 3: The compressed mixed gas is discharged from the screw air compressor 2 and enters the oil-gas separator 3; here, most of the oil medium is separated to obtain compressed air with very little oil content.

[0018] Air cooler 4: The compressed air then enters the air cooler 4 and is cooled by the fan 5. This step is to reduce the air temperature so that it will not overheat during use. At the same time, the oil separated from the oil-gas separator 3 also enters the air cooler 4 for cooling, and then returns to the screw air compressor 2 for recycling after passing through the oil filter 6.

[0019] Pipeline transportation: The cooled compressed air is transported to the place of use through pipelines.

[0020] Exhaust collection hood 7 and axial flow fan 8: The hot air exhausted from the air cooler 4 is collected by the exhaust collection hood 7 and quickly exhausted from the air compressor room by the axial flow fan 8 to maintain the indoor temperature and prevent overheating.
