Description

Technical Field

[0001] The utility model relates to a multi-stage air pre-processing device and a mounting structure thereof, belonging to the technical field of air maintenance processing devices of air conditioners. Background Art

[0002] If the customer needs to operate additional air control devices on the machine, it is usually necessary to install an air maintenance device to reduce the daily maintenance of the machine and effectively avoid the risk of oil and dust particles in the air source damaging the machine components. The air maintenance device itself has a compressed air monitoring function to ensure that changes in air pressure can be identified.

[0003] The air maintenance device currently used consists of the air maintenance device itself (i.e., the condensed water container 7) and the air filter 9. It has a pointer-type pressure gauge 4 and a digital sensor for detecting compressed air (i.e., the compressed air monitoring sensor device 6). The hand wheel (i.e., the knob 3) can adjust the working pressure of the air maintenance device (e.g., Figure 1 As shown), the end of the condensate container 7 is connected to a condensate release valve 8, one end of the air filter 9 is connected to the compressed air supply connection port 1, and the other end is connected to the customer connection port 5, and the compressed air monitoring sensor device 6 is connected to the air filter 9.

The existing injection molding machine clamping unit frame 15 has a cavity structure below the control panel 13, but its volume is small and the existing air maintenance device cannot be installed therein.

[0005] The currently used air maintenance device is only equipped with a compressed air monitoring sensor device 6 (such as Figure 2 As shown, it includes a connector 63 connected to the air filter 9, the connector 63 is connected to the pressure switch 62, and the pressure switch 62 is connected to the first connecting cable 61. If other pressure monitoring and pressure control requirements of the injection molding machine are to be met, such as the pneumatic control nozzle switch function, monitoring the pressure of the external input air source, etc., an analog sensor needs to be configured separately, which increases the cost. If a machine has several points that require air detection, it is necessary to install several such devices at different locations of the machine, and multiple devices increase the maintenance cost.
