Description

Automatic condensed water discharging device in micro-negative pressure environment

Technical Field

The utility model relates to the technical field of automatic condensate water discharge, in particular to an automatic condensate water discharge device in a micro-negative pressure environment.

Background

In the existing compressed air system, in order to prevent excessive condensed water generated in the process of compressing air from being stored in equipment (such as a gas storage tank), a condensed water outlet is usually arranged at the bottom of the equipment, a drain pipe is connected at the condensed water outlet, and a drain electromagnetic valve is utilized to control the condensed water to be automatically discharged at fixed time; in order to prevent accumulation of the remaining amount after each drain of the condensed water, the drain timing value must be set at the maximum precipitation amount of the condensed water. This results in that in most cases, part of the compressed air is emptied after the condensed water is discharged, so that energy waste is caused; and because the condensed water is directly stored in the equipment (such as a gas storage tank), the accumulated amount of the condensed water in the equipment, the drainage working condition and other parameters cannot be intuitively known, and the manual intervention is inconvenient. For example, chinese patent publication No. CN112414200a discloses an automatic condensed water discharge device for an on-board evaporator. Comprises an evaporator shell, an evaporation fan, a vent pipe, a drain pipe and a valve body; the valve body inner cavity forms a three-way structure, and a valve plate is rotatably arranged in the valve body inner cavity.

However, the above scheme has the following disadvantages: in the process of discharging the condensed water, the evaporation fan is required to be operated all the time to maintain the negative air pressure in the evaporator shell so as to continuously discharge the condensed water, and energy waste can be caused; therefore, we propose an automatic condensed water discharge device under a micro-negative pressure environment.

Compared with the prior art, the utility model has the beneficial effects that: when the water level rises to a position where the first floating block floats and rises, the first floating block can lift with the arc-shaped block connected with the lower end, and the second gear can rotate anticlockwise due to the fact that the buoyancy of the air bag is greater than the gravity of the weight block and the air bag in a submerged state, so that the blocking rod rotates to the lower left side of the second gear, and the door valve is opened and begins to drain;

when the water level starts to descend, the first floating block also brings the L-shaped rod to the descending position of the arc-shaped block connected with the lower end, so that the lower end of the arc-shaped block is contacted with the blocking rod; even if the water level continuously descends, the buoyancy of the air bag slowly becomes smaller than the gravity of the weight, the weight can not drive the second gear to rotate clockwise, but the door valve can not be closed because the blocking rod is blocked by the lower end of the arc-shaped block again, when the water level is lowered to the position where the second floating block descends, the transmission rod is driven by the first gear to vertically move upwards, so that the blocking rod is separated from the disorder of the arc-shaped block, the weight can drive the second gear to rotate clockwise under the action of gravity, and the third gear is driven to close the door valve; because the transmission rod pushes the arc-shaped block to rise in position and the water level when the gate valve is closed is higher than the top height of the water outlet, the gas in the water draining tank and the gas tank can not be discharged, the factor of maintaining the micro negative pressure environment in the gas tank is achieved, and the energy can be saved.

Specifically, when the condensed water 4 flows into the drain tank 3 in use, the second gear 12 drives the third gear 16 to enable the gate valve 17 to be in a closed state due to the gravity influence of the weight 124;

when the water level of the condensed water 4 continuously rises, the second floating block 9 is driven to rise along the inner cavity of the circular tube 5, so that the first gear 15 is driven to rotate clockwise, and the transmission rod 13 meshed with the first gear is driven to vertically move downwards;
