Description

Technical Field

[0001] The utility model relates to the field of acid flushing of a water sample evaporator fan, in particular to a fan which is convenient for acid flushing. Background Art

[0002] The fan is connected to the water sample evaporator. The water sample evaporator evaporates the acidified water sample. The fan promptly extracts and discharges the acidified water vapor evaporated by the water sample evaporator. Over time, acid residue will remain on the fan blades and inner wall of the fan, which will corrode the fan blades and motor and affect the life of the fan. Therefore, the residual acid needs to be removed. Therefore, how to conveniently remove the residual acid in the fan is an urgent problem that technicians in this field need to solve. Utility Model Content

[0003] The purpose of the utility model is to provide a fan that is convenient for acid flushing, so as to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fan for convenient acid flushing, comprising a casing capable of left and right ventilation, a motor installed in the casing, and blades installed on the motor shaft. The connection between the motor and the blades and the corresponding components are all existing technologies and will not be described in detail. The upper end of the casing is provided with a flushing mechanism for flushing the motor and the blades downwards. The flushing mechanism flushes the motor and the blades from the upper side, and the lower end of the casing is connected to a drainage mechanism for extracting the waste water flowing down from the flushing mechanism. The drainage mechanism discharges the waste liquid after flushing.

[0005] Preferably, the flushing mechanism includes a water inlet chamber arranged at the upper end of the casing, and water inlet holes located in the water inlet chamber are evenly opened at the upper end of the casing. The water inlet chamber is connected to a liquid inlet solenoid valve through a water inlet pipe. When the liquid inlet solenoid valve is opened and the water inlet chamber is filled with water, it is sprayed toward the motor and blades for flushing, thereby avoiding or reducing acid corrosion of the motor and blades.

[0006] Preferably, the water inlet pipe is connected to a water inlet pump to increase the water inlet pressure.

[0007] Preferably, the water inlet holes are arranged at equal intervals along the left-right direction, and the water inlet holes are in the shape of strips along the circumferential direction of the casing, which is consistent with the rotation direction of the blades.

[0008] Preferably, the drainage mechanism includes a drainage cavity arranged at the lower end of the casing, and the lower end of the casing is evenly provided with drainage holes located in the drainage cavity. The drainage cavity is connected to a liquid outlet solenoid valve through a drainage pipe. Preferably, acid corrosion-resistant can be used here because there is a large amount of water during flushing, and there is very little acid after dilution.

[0009] Preferably, the end of the drain pipe is connected to a drain pump to increase drainage suction.

[0010] Preferably, the drainage holes are arranged at equal intervals along the left-right direction, and the drainage holes are strip-shaped along the circumferential direction of the casing, consistent with the rotation direction of the blades. At the same time, acidic substances are not easy to slide out along the axial direction.

[0011] Preferably, the water inlet cavity and the drainage cavity are both flat and in an arc shape with the axis of the casing, so that the pressure is more balanced.

[0012] Preferably, the diameters of the two ends of the casing are smaller than the middle, and the water inlet cavity and the drainage cavity are located in the middle for spraying and draining water. Water is easy to gather at the bottom and is not easy to splash on both sides when spraying.

[0013] Preferably, the rear end of the housing is provided with a mounting plate for easy installation on a wall, ensuring that the air inlet is located at the top and the drainage hole is located at the bottom.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. After power is turned on, the liquid inlet solenoid valve, water inlet pump, liquid outlet solenoid valve and drain pump work, and the water in the water inlet cavity is sprayed to the motor and blades through the water inlet hole, thereby flushing away the acid. At the same time, the water inlet hole is strip-shaped, with a large flushing area, and the water will flow down along the motor and blades to ensure a clean flush. At the same time, as an option, the water inlet hole can also be tilted to facilitate flushing of the motor and the bottom of the blades. As an option, a second cleaning can also be performed after the blades rotate to ensure cleanliness and flexible use.

[0016] 2. The waste water is located at the bottom of the casing. Open the liquid outlet solenoid valve and the drain pump to pump out the waste water. You can also pump for a while to ensure that the bottom is clean. After the end, close the liquid inlet solenoid valve and the liquid outlet solenoid valve to ensure sealing.
