Abstract
The utility model relates to a dehumidifying device used for an air compressor. The dehumidifying device used for the air compressor is characterized by comprising a refrigeration device composed of a refrigeration compressor, a condenser and an evaporator. The evaporator is arranged in a dehumidifying box (3a), an inlet a and an outlet b of compressed air are arranged on the upper portion of the dehumidifying box (3a), a liquid drainage hole (3d) of condensate is formed in the lower portion of the dehumidifying box (3a) and connected with a liquid drainage magnetic valve (3e) through a pipeline, and a liquid level sensor (3d) is arranged at the liquid drainage hole position in the dehumidifying box (3a). The liquid level sensor (3d) and the liquid drainage magnetic valve (3e) are respectively connected with a PLC through data lines, the output of the PLC is connected with a frequency converter, and the frequency converter is connected with the refrigeration compressor. The dehumidifying device used for the air compressor has the advantages that through detection of condensation water volume generated by a cooler in the dehumidifying device in the air compressor, switching of the liquid drainage magnetic valve is controlled, energy consumption is reduced and production cost is low.
Description
Technical field
The present invention relates to the dehumidifier in a kind of air compressor.
Background technique
The pressurized air of discharging from compressor contains moisture and oil, and the pressurized air that contains moisture and oil for using compressed-air actuated equipment is and is harmful.Therefore air compressor generally all needs to arrange the pressurized air dehumidifier.
More existing pressurized air dehumidifiers, wherein condensed fluid discharge frequency is decided by the compressed air cylinder internal pressure, but the reason owing to season and weather, when even the load of air compressor increases, and under the less situation of the actual condensed water that produces, condensate discharging device meeting frequent starting causes to waste energy.If by manual switching, cause shortcomings such as operating difficulties, accuracy be relatively poor.
The model utility content:
The purpose of this utility model is exactly the defective that exists in the prior art in order to solve, and a kind of dehumidifier for air compressor is provided.
To achieve these goals, the utility model has adopted following technological scheme:
A kind of dehumidifier for air compressor, comprise the air compressor, compressed air storage tank and the filter that connect successively, it is characterized in that: connect a dehumidifier between holding vessel and the filter, dehumidifier comprises by refrigeration compressor, condenser, vaporizer forms refrigeration plant; Other arranges a pressurized air except wet tank, vaporizer is arranged on except in the wet tank, the dehumidifying upper box part is provided with compressed-air actuated import a, outlet b, the dehumidifying lower box part is provided with the outage of condensed fluid, outage connects a draining solenoid valve by pipeline, and except outage position in the wet tank is provided with a liquid level sensor, liquid level sensor and draining solenoid valve connect PLC by datawire respectively, PLC output connects frequency variator, and frequency variator links to each other with refrigeration compressor.
Advantage of the present utility model is: by the condensation water quantity that the cooler that detects in the dehumidifier in the air compressor produces, control the switching of draining solenoid valve, cut down the consumption of energy and advantage that cost of production is lower to reach.
Description of drawings:
Fig. 1 uses system construction drawing of the present utility model;
Fig. 2 is the structure principle chart of dehumidifier among Fig. 1.
Embodiment
As shown in Figure 1, a kind of dehumidifier for air compressor that the utility model provides, comprise the air compressor 1, compressed air storage tank 2 and the filter 4 that connect successively, connect a dehumidifier 3 between holding vessel 2 and the filter 4, holding vessel 2 by pipeline be connected with import a, filter 4 by pipeline with export b and be connected.
As shown in Figure 2, dehumidifier 3 comprises by refrigeration compressor, condenser, vaporizer and forms refrigeration plant.Other arranges a pressurized air except wet tank 3a, vaporizer is arranged on except among the wet tank 3a, and the coil pipe 3b of vaporizer is arranged on except among the wet tank 3a, one group of radiating fin 3f is set on the coil pipe 3b, except wet tank 3a top is provided with compressed-air actuated import a, outlet b, be provided with the outage 3d of condensed fluid except wet tank 3a bottom, outage connects a draining solenoid valve 3e by pipeline, except outage position among the wet tank 3a is provided with a liquid level sensor 3d, liquid level sensor 3d and draining solenoid valve 3e connect PLC by datawire respectively, PLC output connects frequency variator, and frequency variator links to each other with refrigeration compressor.
Working procedure of the present utility model is as follows:
The high temperature compressed air that holding vessel is sent here has import a to enter except in the wet tank, carries out heat exchange with vaporizer, and high temperature compressed air temperature decrease, moisture wherein, oil content produce condensed fluid rapidly and be deposited to except the wet tank bottom.When condensed fluid reached the liquid level sensor setting value, liquid level sensor sent a signal to PLC, and PLC sends the unblanking draining solenoid valve and discharges condensed fluid.PLC also sends a signal to frequency variator, and frequency variator is then controlled the operating condition of refrigeration compressor.
