Description

Technical Field

[0001] This patent application belongs to the field of continuous casting machine control technology in the metallurgical industry, and more specifically, it relates to an air circulation structure for a silent and energy-saving air water making machine. Background Art

[0002] The traditional air water generator structure has a sealed evaporator and condenser, and the layout of each structure is relatively loose, so a high-speed fan must be used to achieve a better heat dissipation effect, but at the same time it brings problems such as high noise and high air outlet temperature. Using a single low-speed fan can reduce some wind noise, but it cannot meet the heat dissipation requirements of the condenser, and the air outlet will still have a high temperature, which is not suitable for use in a closed environment. When using a low-speed fan, due to the reduction of negative pressure at the air inlet, the air circulation will also decrease, resulting in a decrease in water production efficiency. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a silent and energy-saving air circulation structure for an air water making machine, which uses fans of various specifications to ensure the water making efficiency is the same as that of a high-speed and large-air-volume fan, while significantly reducing wind noise and lowering the temperature of the air outlet.

[0004] In order to solve the above problems, the technical solution adopted by the present invention is:

[0005] A silent and energy-saving air circulation structure for an air water making machine comprises an air inlet fan fixing plate arranged on the air inlet side of a water making mechanism, an air inlet fan frame arranged on the air inlet fan fixing plate, a plurality of air inlet fans arranged on the air inlet fan frame, an air outlet fan fixing plate arranged on the air outlet side of the water making mechanism, an air outlet fan arranged on the air outlet fan fixing plate, an extended air outlet duct connected to an air outlet fan volute and extending out of an edge of the air outlet fan fixing plate, and an air outlet arranged at the air outlet of the extended air outlet duct.

[0006] A further improvement of the technical solution of the present invention is that the water making mechanism includes an evaporator arranged on the air inlet fan fixing plate on the side facing away from the air inlet fan through a fixing plate 1, a condenser arranged on the air outlet fan fixing plate on the side facing away from the air outlet fan through a fixing plate 2, and a heat exchange gap arranged between the evaporator and the condenser. The upper and lower sides of the evaporator and the condenser are both sealed, and the heat exchange gap is provided with gap holes corresponding to the evaporator and the condenser.

[0007] A further improvement of the technical solution of the present invention is that the heat exchange gap is a partition plate, and a circular or square gap hole is provided on the partition plate.

[0008] A further improvement of the technical solution of the present invention is that the air inlet fan is a small axial flow fan or a small centrifugal fan, the air outlet fan is a centrifugal fan with low speed and large diameter blades, and the extended air outlet duct is made of high thermal conductivity metal material.

[0009] The further improvement of the technical solution of the present invention is that the number of air inlet fans is 2-15, and the maximum flow rate of the air inlet fans is 2000m 3 / min; the speed of the exhaust fan is less than 1000r / min and the blade diameter of the exhaust fan is greater than 800mm.

[0010] A further improvement of the technical solution of the present invention is that the extended air outlet duct is a cube or a cylinder, and is made of copper, aluminum or stainless steel. The length of the extended air outlet duct is 1.2-2.5 times the height of the evaporator or condenser, and the air outlet is oriented to the upper side, side or bent.

[0011] A further improvement of the technical solution of the present invention is that the specifications of the fixing plate 1 and the fixing plate 2 are equal, the height of the air inlet fan fixing plate and the air outlet fan fixing plate are the same as the fixing plate 1, and the width is wider than the fixing plate 1.

[0012] A further improvement of the technical solution of the present invention is that the specifications of the air inlet fan fixing plate and the air outlet fan fixing plate are equal.

[0013] A further improvement of the technical solution of the present invention is that the outer edge of the width direction of the air inlet fan fixing plate extends 5-20 cm from the edge of fixing plate one, and the outer edge of the width direction of the air outlet fan fixing plate extends 5-20 cm from the edge of fixing plate two.

[0014] Due to the adoption of the above technical solution, the beneficial effect achieved by the present invention is that the present structural design uses fans of various specifications to ensure the same water production efficiency as that of a high-speed, high-air-volume fan while significantly reducing wind noise and lowering the temperature of the air outlet.

[0015] The use of this device can improve the water-making efficiency of the machine, reduce wind noise, reduce the heat discharged from the air outlet, and reduce energy consumption while ensuring the heat dissipation effect of the condenser, which is in line with the concept of green environmental protection.

DETAILED DESCRIPTION

[0019] The present invention is further described in detail below with reference to the embodiments.

[0020] The present invention discloses a silent and energy-saving air circulation structure for an air water making machine, see Figure 1 , Figure 2 , including an air inlet fan fixing plate 3 arranged on the air inlet side of the water making mechanism 11, an air inlet fan frame 1 arranged on the air inlet fan fixing plate 3, a plurality of air inlet fans 2 arranged on the air inlet fan frame 1, an air outlet fan fixing plate 7 arranged on the air outlet side of the water making mechanism 11, an air outlet fan 8 arranged on the air outlet fan fixing plate 7, an extended air outlet duct 9 connected to the volute of the air outlet fan 8 and extending out of the edge of the air outlet fan fixing plate 7, and an air outlet 10 arranged at the air outlet of the extended air outlet duct 9.

[0021] The water making mechanism 11 includes an evaporator 4 arranged on the air inlet fan fixing plate 3 on the side facing away from the air inlet fan 2 through a fixing plate 12, a condenser 5 arranged on the air outlet fan fixing plate 7 on the side facing away from the air outlet fan 8 through a fixing plate 2 13, and a heat exchange gap 6 arranged between the evaporator 4 and the condenser 5. The upper and lower sides of the evaporator 4 and the condenser 5 are both sealed, and the heat exchange gap 6 is provided with gap holes corresponding to the evaporator 4 and the condenser 5.

[0022] The heat exchange gap 6 is a partition plate, and a circular or square gap hole is arranged on the partition plate.

[0023] The air inlet fan 2 is a small axial flow fan or a small centrifugal fan, the air outlet fan 8 is a centrifugal fan with low speed and large diameter blades, and the extended air outlet duct 9 is made of a high thermal conductivity metal material.

[0024] The number of air inlet fans 2 is 2-15, and the maximum flow rate of air inlet fans 2 is 2000m 3 / min; the rotation speed of the air outlet fan 8 is less than 1000r / min, and the blade diameter of the air outlet fan 8 is greater than 800mm.

[0025] The extended air outlet duct 9 is a cube or a column, and is made of copper, aluminum or stainless steel. The length of the extended air outlet duct 9 is 1.2-2.5 times the height of the evaporator 4 or the condenser 5, and the air outlet 10 is oriented upward, side or bent.

[0026] The specifications of the fixing plate 1 12 and the fixing plate 2 13 are equal, and the height of the air inlet fan fixing plate 3 and the air outlet fan fixing plate 7 is the same as that of the fixing plate 1 12 , and the width is wider than that of the fixing plate 12 .

[0027] The specifications of the air inlet fan fixing plate 3 and the air outlet fan fixing plate 7 are equal.

[0028] The outer edge of the air inlet fan fixing plate 3 in the width direction extends 5-20 cm beyond the edge of the fixing plate 12 , and the outer edge of the air outlet fan fixing plate 7 in the width direction extends 5-20 cm beyond the edge of the fixing plate 2 13 .

[0029] The process of the present invention is as follows: humid air is drawn into the water-making mechanism 11 of the air water-making machine by multiple groups of air inlet fans 2 (small fans) fixed on the air inlet fan frame 1, and the humid air flows through the low-temperature evaporator 4, and the moisture in the air is reduced to below the dew point and condensed to form liquid water. The remaining dry cold air enters the high-temperature condenser 5 through the heat exchange gap 6, and the cold air absorbs heat and takes away part of the heat to become hot air, and the condenser 5 continues to heat it to become higher temperature air. The higher temperature air is drawn out through the outlet fan 8 (centrifugal fan) and enters the outlet duct 9 made of high thermal conductivity metal. The higher temperature air in the outlet duct 9 transfers heat to the outer wall of the duct, and the heated metal outer wall of the outlet duct 9 radiates heat outward to dissipate part of the heat. After a certain length of the extended outlet duct 9, the hot air is discharged from the outlet 11.

[0030] The present invention uses multiple groups of air inlet fans 2 to perform air suction operations on the air inlet side of the evaporator 4 of the water making mechanism 11, thereby increasing the air volume at the air inlet, so as to solve the problem of insufficient negative pressure at the air inlet and too small air volume after the main fan reduces the air volume. A low-speed and large-blade-diameter air outlet fan 8 is used to reduce noise troubles, while avoiding the problem of overheating of the condenser caused by the exhaust volume not being too small. The extended air outlet duct 9 is made of metal material, so that part of the heat of the hot air can be dissipated through the metal duct wall to reduce the temperature of the air outlet 10. At the same time, the present invention fixes the evaporator 4 and the condenser 5 on the fixing plate 1 12 and the fixing plate 2 13 of the same specifications, respectively, and seals the upper and lower sides to form an integrated semi-sealed water making mechanism 11. The evaporator 4 and the condenser 5 are close together, and the cold air flowing through the evaporator 4 immediately passes through the condenser 5, thereby taking away part of the heat generated by the condenser 5, thereby reducing the heat dissipation pressure. The present invention can replace the low-power fan to reduce energy consumption, and has better practicality and applicability than the traditional split-type water making machine technology of using cold air to dissipate heat.
