Description

Technical Field

[0001] The utility model relates to an integral high-efficiency air handling unit scroll tongue, in particular to an anti-turbulence integral high-efficiency air handling unit scroll tongue, belonging to the technical field of air handling units. Background Art

[0002] An air handling unit generally includes a cabinet body, a surface cooler (heat exchanger) and a fan with a volute. After the fan blows air to the surface cooler, the air is cooled by heat exchange and then blown out of the cabinet body, so as to achieve the regulation of air temperature.

[0003] Chinese Patent No. CN211233230U provides an air handling unit, including: a fan box, with air inlets provided on the left and right sides of the fan box; an air outlet cavity, communicated with the fan box; a fan position, where a fan is installed and communicated with the air outlet cavity; an air inlet position, provided on the fan position and communicated with the corresponding air inlet. The utility model provides an air handling unit structure, which completes the air guiding through the superposition structure of the upper channel and the lower channel, replaces the previous straight-in and straight-out structure, and provides an air handling unit structure with uniform air outlet.

[0004] However, although the above case can provide an air handling unit structure with uniform air outlet, all current domestic air handling units adopt a single scroll tongue, which has the following disadvantages:

[0005] The scroll tongue is not firmly fixed, and connection loosening or falling may occur during use. After falling, it is easy to cause secondary damage to the impeller, and there is a certain safety hazard;

[0006] The end wall of the scroll tongue is a semi-circular structure. If the installation angle is not appropriate, a whistling sound will appear, which is not conducive to noise reduction;

[0007] Due to the remaining space in area A of the scroll tongue, eddy current phenomenon will occur in the air flow, which will consume internal power and generate reactive power, thereby reducing the total pressure efficiency of the air handling unit;

[0008] Due to the remaining space in area A of the scroll tongue, turbulence phenomenon will occur, which is also a very important source of noise generation;

[0009] 5. This single scroll tongue is severely deformed, difficult to assemble, and it is very difficult to control the gap between the scroll tongue and the air inlet, which has a certain impact on the air volume and air pressure.

[0010] In view of this, the present utility model is particularly proposed. Content of the Utility Model

[0011] The purpose of the present utility model is to provide an anti-turbulence integral high-efficiency air handling unit scroll tongue in order to solve the above problems.

[0012] The present utility model realizes the above object through the following technical solutions. An anti-turbulence integral high-efficiency air handling unit scroll tongue includes a scroll housing assembly, a scroll tongue assembly and an impeller assembly. The scroll tongue assembly is arranged on one side of the inner wall of the scroll housing assembly, and the impeller assembly is arranged on one side of the inner wall of the scroll housing assembly.

[0020] Technical effects and advantages of the present utility model: (1) The volute tongue part of the present utility model is designed based on the principle that a triangle has the highest stability. The volute tongue part is fixed by three points through lugs, which is very firm. During use, there will be no deformation or displacement, and it will not cause secondary damage to the impeller, being absolutely safe and reliable. At the same time, this new type of volute tongue part enables the gas to move forward at a reasonable expansion angle, conforming to the principle of aerodynamics, which can reduce the aerodynamic resistance and improve the total pressure efficiency of the air handling unit. Moreover, the area formed between the volute tongue part and the volute is in a closed state, there is no environment of gas flow blockage, and no reactive power will be generated, which can improve the total pressure efficiency of the air handling unit.

Detailed implementation mode

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-6 As shown, a turbulenceless integral high-efficiency air handling unit scroll tongue includes a scroll housing assembly 100, a scroll tongue assembly 200, and an impeller assembly 300. The scroll tongue assembly 200 is arranged on one side of the inner wall of the scroll housing assembly 100, and the impeller assembly 300 is arranged on one side of the inner wall of the scroll housing assembly 100. The scroll tongue assembly 200 includes a scroll tongue member 201, and lugs 202 are welded to the outer wall of one side of the scroll tongue member 201. The scroll tongue member 201 is installed on the inner wall of the scroll housing assembly 100 by bolts. The scroll tongue member 201 is integrally formed. A plurality of through holes are formed on the outer walls of both sides of the scroll tongue member 201. The lugs 202 are installed inside the scroll housing assembly 100 by M8*15 bolts and Φ5*10 blind rivets made of aluminum. The scroll tongue member 201 is designed based on the principle that a triangle has the best stability. The scroll tongue member 201 is fixed by three points through the lugs 202, which is very firm. During use, there will be no deformation and displacement, and it will not cause secondary damage to the impeller, which is absolutely safe and reliable. At the same time, this new type of scroll tongue member 201 enables the gas to move forward at a reasonable expansion angle, which conforms to the principle of aerodynamics, can reduce the aerodynamic resistance, and improve the total pressure efficiency of the air handling unit. Moreover, the area formed between the scroll tongue member 201 and the scroll housing 101 is in a closed state, there is no environment of gas blockage, and no reactive power will be generated, which can improve the total pressure efficiency of the air handling unit. At the same time, the scroll tongue member 201 and the scroll housing 101 are tightly riveted without gaps, and no rattling noise will be generated during the operation of the air handling unit, which can reduce the noise at the air outlet of the air handling unit.

[0030] As a technical optimization scheme of the present invention, the scroll housing assembly 100 includes a scroll housing 101. An installation part 102 is welded to one side of the inner wall of the scroll housing 101. Four installation cylinders 106 are arranged on the outer wall of one side of the scroll housing 101. The scroll housing 101 includes a core body 112, which is made of sound-absorbing material and can improve the noise resistance of the scroll housing 101. A metal layer 113 is wrapped outside the core body 112.

[0031] As a technical optimization solution of the present utility model, an installation area 108 is provided on the outer wall of one side of the installation cylinder 106, and piston blocks 110 are slidably inserted at both openings of the installation area 108. A connecting spring 109 is installed between the two piston blocks 110 by bolts. When the piston plate 105 returns to the original position in the oil storage cavity 103, the hydraulic oil is not under pressure. During this process, under the action of the connecting spring 109, the two piston blocks 110 will drive the limiting plate 107 back to the original position, so that the fixation between the volute 101 and the air cabinet is released, facilitating the worker to quickly disassemble the device. One end of the piston block 110 is integrally formed with a limiting plate 107. An oil storage cavity 103 is provided on the volute 101. The oil storage cavity 103 is interconnected with the installation area 108 through a pipeline. Hydraulic oil is filled between the oil storage cavity 103 and the installation area 108. One outer wall of the volute 101 is installed with an adjusting bolt 104 through a bearing, and the output end of the adjusting bolt 104 is threadedly connected with a piston plate 105. By rotating the adjusting bolt 104, the adjusting bolt 104 will drive the piston plate 105 to move, so that the piston plate 105 moves inside the oil storage cavity 103. During this process, the piston plate 105 will push the hydraulic oil inside the oil storage cavity 103 to flow, and then the hydraulic oil will flow into the installation cylinder 106 through the pipeline. Subsequently, the hydraulic oil will enter the installation area 108 and squeeze the piston blocks 110. Then, the two limiting plates 107 will extend and expand, so that the volute 101 is fixed on the air cabinet, and the piston plate 105 is still connected inside the oil storage cavity 103.

[0032] As a technical optimization solution of the present utility model, the impeller assembly 300 includes a fixing plate 301. The fixing plate 301 is installed on one side of the inner wall of the volute 101 through a bearing. A plurality of blades 302 are welded on the outer wall of one side of the fixing plate 301. When the fixing plate 301 rotates, the rotation of the blades 302 will cause gas flow inside the volute 101, so that air is blown out inside the volute 101, and a fixing ring 303 is welded at one end of the plurality of blades 302.

[0033] When the utility model is in use, the volute 101 can be first butted with the air handling unit, and then the worker can rotate the adjusting bolt 104. Then, the adjusting bolt 104 will drive the piston plate 105 to move, so that the piston plate 105 moves inside the oil storage cavity 103. In this process, the piston plate 105 will push the hydraulic oil inside the oil storage cavity 103 to flow. Subsequently, the hydraulic oil will flow into the installation cylinder 106 through the pipeline. Then, the hydraulic oil will enter the placement area 108 and extrude the piston block 110. Subsequently, the two limiting plates 107 will extend and unfold, so that the volute 101 is fixed on the air handling unit. When the impeller assembly 300 inside the air handling unit moves subsequently, air will flow inside the volute 101, causing the air handling unit to start running. In this process, since the area formed between the volute tongue member 201 and the volute 101 is in a closed state, there is no environment of gas blockage and no reactive power will be generated, greatly improving the total pressure efficiency of the air handling unit. And because the volute tongue member 201 and the volute 101 are tightly riveted without leaving a gap, with the design of the core body 112, the noise generated when the impeller assembly 300 inside the volute 101 moves can be reduced.
