Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pipeline noise reduction, and specifically relates to an operation noise reduction device for a magnetic suspension chiller. Background Art
[0002] Magnetic levitation chillers are widely used in various fields due to their high efficiency, energy saving, oil-free operation, and easy maintenance. During operation, a magnetic levitation chiller compresses the refrigerant through a compressor and transfers it to the condenser for heat release. The refrigerant then passes through a throttling device and enters the evaporator for heat absorption, completing the refrigeration cycle. During this process, the flow of refrigerant in the pipes, the operation of the compressor, and the connections between the chiller and the pipes can all become sources of noise. This noise not only affects the quietness of the indoor environment but can also disturb nearby residents and workers, and even adversely affect the long-term stable operation of the equipment.
[0003] In addition, during the operation of the chiller, the air flow flushes the pipes, and when the bypass valve is opened, the bypass valve cannot be fully opened. The throttling effect of the bypass valve causes the unit to run noisy; when the air flow passes through the volute, the sound of flushing the volute is loud.
[0004] During the actual operation of the project, noise pollution is very harmful to the human body. Therefore, more and more attention is paid to the prevention and control of noise during use. In order to adapt to more usage sites, the sound insulation and noise reduction functions are increasingly valued. Utility Model Content
[0005] The main technical problem to be solved by the utility model is to provide a magnetic levitation chiller operation noise reduction device with a simple overall structure, which can cool down and isolate the pipes in the unit during the operation of the magnetic levitation chiller, has low cost, a wide range of applications, and improves the use effect.
[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0007] A magnetic levitation chiller operation noise reduction device includes an intake pipe, a first thermal insulation rubber layer is adhered to the outer surface of the intake pipe, a third thermal insulation cotton layer is adhered to the outer surface of the first thermal insulation rubber layer, a second thermal insulation rubber layer is adhered to the outer surface of the third thermal insulation cotton layer, the first thermal insulation cotton layer is provided on the outer surface of the second thermal insulation rubber layer, a third thermal insulation rubber layer is provided on the outer surface of the first thermal insulation cotton layer, a noise reduction cotton layer is adhered to the outer surface of the third thermal insulation rubber layer, and an aluminum skin layer is provided on the outer surface of the noise reduction cotton layer.
[0008] The following is a further optimization of the above technical solution by the present invention:
[0009] The thickness of the third thermal insulation cotton layer is set to 2-3 cm.
[0010] Further optimization: the thickness of the first thermal insulation cotton layer is set to 2-3 cm.
[0011] Further optimization: the thickness of the noise reduction cotton layer is set to 2-3 cm.
[0012] Further optimization: the thickness of the aluminum skin layer is set to 0.5-1 mm.
[0013] The utility model adopts the above technical solution, which is ingenious in conception and reasonable in structure. It can insulate and reduce noise of various pipes in the magnetic levitation chiller during operation of the magnetic levitation chiller, thereby reducing noise pollution and maintaining the health of staff. At the same time, an aluminum layer is used to cover the outside of the noise reduction cotton layer to protect the third insulation cotton layer, the first insulation cotton layer and the noise reduction cotton layer from scratches during use, which affects the insulation and noise reduction effects. The third insulation cotton layer, the first insulation cotton layer and the noise reduction cotton layer can be cut according to the pipe model and size. Therefore, the noise reduction device for the operation of the magnetic levitation chiller can also be applied to pipes other than the intake pipe, the exhaust pipe and the secondary pipe, thereby improving the wide range of applications.
[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0024] Example 1: Figure 1-5 As shown together, a magnetic levitation chiller operation noise reduction device includes an intake pipe 100, a first thermal insulation rubber layer 1 is adhered to the outer surface of the intake pipe 100, a third thermal insulation cotton layer 2 is adhered to the outer surface of the first thermal insulation rubber layer 1, a second thermal insulation rubber layer 3 is adhered to the outer surface of the third thermal insulation cotton layer 2, a first thermal insulation cotton layer 4 is provided on the outer surface of the second thermal insulation rubber layer 3, a third thermal insulation rubber layer 5 is provided on the outer surface of the first thermal insulation cotton layer 4, a noise reduction cotton layer 6 is adhered to the outer surface of the third thermal insulation rubber layer 5, and an aluminum skin layer 7 is provided on the outer surface of the noise reduction cotton layer 6.
[0025] In this embodiment 1, the air intake pipe 100 is an air intake pipe commonly used in a magnetic levitation chiller. When the device is used, the outer surface of the air intake pipe 100 is first derusted and painted with anti-rust paint.
[0026] The first thermal insulation adhesive layer 1 is made by brushing thermal insulation glue that can be directly purchased on the market on the outer surface of the intake pipe 100, and then the third thermal insulation cotton layer 2 is adhered to the first thermal insulation adhesive layer 1. With this design, the third thermal insulation cotton layer 2 can firmly cover the intake pipe 100.
[0027] The second thermal insulation adhesive layer 3 is also made by brushing thermal insulation glue that can be directly purchased on the market on the outer surface of the third thermal insulation cotton layer 2, and then the first thermal insulation cotton layer 4 is adhered to the second thermal insulation adhesive layer 3. In this design, the first thermal insulation cotton layer 4 can be firmly wrapped on the third thermal insulation cotton layer 2.
[0028] The third thermal insulation adhesive layer 5 is also made by brushing thermal insulation glue that can be directly purchased on the market on the outer surface of the first thermal insulation cotton layer 4, and then the noise reduction cotton layer 6 is firmly covered on the outer surface of the first thermal insulation cotton layer 4.
[0029] The materials used for the third thermal insulation cotton layer 2, the first thermal insulation cotton layer 4 and the noise reduction cotton layer 6 are rubber-plastic board thermal insulation and noise reduction materials commonly used on the market, which can be directly purchased from the market.
[0030] The thickness of the third thermal insulation cotton layer 2, the first thermal insulation cotton layer 4 and the noise reduction cotton layer 6 are all set to 2.5 cm.
[0031] The principle by which the thermal insulation and noise reduction material can achieve thermal insulation and noise reduction is well known in the prior art and will not be described in detail here.
[0032] The aluminum skin layer 7 is directly wrapped on the outer surface of the noise reduction cotton layer 6.
[0033] The thickness of the aluminum skin layer 7 is set to 1 mm. The aluminum skin layer 7 can ensure that the third thermal insulation cotton layer 2, the first thermal insulation cotton layer 4 and the noise reduction cotton layer 6 are not scratched during use, and plays a protective role.
[0034] When the magnetic levitation chiller is in use, the outer surface of the air intake pipe 100 is firmly wrapped by the third thermal insulation cotton layer 2, the first thermal insulation cotton layer 4 and the noise reduction cotton layer 6, which can play the role of heat preservation, noise reduction and sound insulation.
[0035] Example 2: Figure 6 As shown, based on Example 1, the intake pipe 100 is replaced with an exhaust pipe 200. The exhaust pipe 200 is an exhaust pipe commonly used in magnetic levitation chillers. When the device is in use, the outer surface of the exhaust pipe 200 is first derusted and painted with anti-rust paint.
[0036] The third thermal insulation cotton layer 2 , the first thermal insulation cotton layer 4 and the noise reduction cotton layer 6 are then firmly covered on the exhaust pipe 200 through the first thermal insulation adhesive layer 1 , the second thermal insulation adhesive layer 3 and the third thermal insulation adhesive layer 5 .
[0037] The aluminum skin layer 7 is directly wrapped on the outer surface of the noise reduction cotton layer 6.
[0038] Example 3: Figure 7 As shown, based on Example 1, the air intake duct 100 is replaced with a bypass duct 300 .
[0039] The bypass pipe 300 is a bypass pipe commonly used in magnetic levitation chillers, and a bypass valve 301 is connected in series to the bypass pipe 300 .
[0040] When the device is used, firstly, the outer surface of the bypass pipe 300 except the bypass valve 301 is subjected to rust removal treatment and painted with anti-rust paint.
[0041] The third thermal insulation cotton layer 2, the first thermal insulation cotton layer 4 and the noise reduction cotton layer 6 are then firmly covered on the outer surface of the bypass pipe 300 except the bypass valve 301 through the first thermal insulation rubber layer 1, the second thermal insulation rubber layer 3 and the third thermal insulation rubber layer 5.
[0042] The aluminum skin layer 7 is directly wrapped on the outer surface of the noise reduction cotton layer 6.
[0043] The outer surface of the valve body of the bypass valve 301 is covered with a second thermal insulation cotton layer 302 .
[0044] During the use of the magnetic levitation chiller, the noise of the valve body mainly comes from the scouring of the air flow. Therefore, the second thermal insulation cotton layer 302 can achieve thermal insulation and noise reduction for the valve body.
[0045] Example 4: Figure 8 As shown, based on Example 1, the air intake pipe 100 is replaced with a secondary pipe 400.
[0046] The diode pipe 400 is a diode pipe commonly used in a magnetic levitation chiller, and a corner is provided on the diode pipe 400.
[0047] When in use, the outer surface of the secondary pipe 400 is derusted and painted with anti-rust paint, and then the third thermal insulation cotton layer 2, the first thermal insulation cotton layer 4 and the noise reduction cotton layer 6 are firmly covered on the outer surface of the secondary pipe 400 through the action of the first thermal insulation rubber layer 1, the second thermal insulation rubber layer 3 and the third thermal insulation rubber layer 5. The corner position is also firmly covered with the third thermal insulation cotton layer 2, the first thermal insulation cotton layer 4 and the noise reduction cotton layer 6 through the action of the first thermal insulation rubber layer 1, the second thermal insulation rubber layer 3 and the third thermal insulation rubber layer 5.
[0048] The aluminum skin layer 7 is directly wrapped on the outer surface of the noise reduction cotton layer 6.
[0049] The third thermal insulation cotton layer 2, the first thermal insulation cotton layer 4 and the noise reduction cotton layer 6 can be cut according to the pipe model and size. Therefore, the magnetic levitation chiller operation noise reduction device can also be applied to pipes other than the intake pipe 100, the exhaust pipe 200 and the secondary pipe 400, thereby improving the wide application range.
[0050] For ordinary technicians in this field, based on the teachings of this utility model, without departing from the principles and spirit of this utility model, changes, modifications, replacements and deformations made to the implementation methods are still within the scope of protection of this utility model.
