A strip-shaped box is fixedly installed between two opposite side walls of the fixed seat, and the strip-shaped box is arranged at the bottom of the rotating cylinder. A blower is fixedly installed at the top of the second base, the input end of the blower extends into the rotating cylinder, and a guiding air duct is installed at the output end of the blower. High-pressure air flow is sprayed on the rotating cylinder from the inside to the outside through a plurality of nozzles, which can clean the dust and impurities on the inner hole wall of the filter holes on the rotating cylinder. The strip-shaped box is used to collect the dust and impurities blown off by impact, and the dust removal hose can flush the dust and impurities in the strip-shaped box into the storage box in the storage box for convenient centralized cleaning; However, the existing water-cooled air suspension centrifugal blower box structure of merchants has the following disadvantages: 1) The air-cooling heat dissipation efficiency is much lower than that of water-cooling. The heat dissipation gas is discharged outside the cabin, resulting in poor efficiency and the risk of dust ingress, and the outlet temperature is too high; 2) If the frequency converter and the blower are in the same cabin or parallel cabins and there is water leakage, there is a risk of water ingress into the frequency converter, leading to accidents such as short circuits and electric shocks; 3) The gas flow directly enters the compressor without passing through the frequency converter, and the heat dissipation efficiency is low; 4) The circuit board and the frequency converter are installed together, and if the water-cooled structure leaks, the circuit board is easily burned; 5) The installation of air release valves in the cabin has a risk of water ingress.

[0018] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. 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 making creative efforts fall within the scope of protection of the present invention. Embodiment 1

[0019] As Figures 1 to 3 shown, this embodiment proposes a water-cooled air suspension centrifugal blower box structure, including a box body shell 1. A partition member 2 is fixedly connected to the inner wall surface of the box body shell 1. The partition member 2 and the box body shell 1 divide the inner cavity of the box body shell 1 into three regions. Among them, the upper, middle, and lower three-layer regions are the frequency converter cabin 3, the air compressor cabin 4, and the intercooler cabin 5 respectively. A set of water-cooling structures 6 are respectively arranged inside the frequency converter cabin 3, the air compressor cabin 4, and the intercooler cabin 5. A water inlet pipe 7 and a water outlet pipe 8 are respectively fixedly connected to one side surface of the box body shell 1. An air outlet 9 is provided on the outer surface of one side of the box body shell 1. An air filter 10 is detachably connected to one side surface of the box body shell 1. A wind guide channel is fixedly connected to the inner wall of one side of the box body shell 1. An air outlet net 11 is arranged at the opening of the wind guide channel.

[0020] A partition member 2 is fixedly connected to the inner surface of the air compressor cabin 4. An external hanging cabin 13 is fixedly connected to the outer surface of one side of the box body shell 1. A control panel 14 is fixedly connected to the surface of the box body shell 1. The air filter 10 is used for air intake. The air flow is discharged into the interior of the box body shell 1 through the air outlet net 11 and is discharged outward through the air outlet 9. The interior of the external hanging cabin 13 is provided with fan electrical components, and the fan electrical components are components that do not require heat dissipation.

[0021] The opening of the wind guide channel is arranged inside the frequency converter cabin 3. The air flow blown out from the inner side of the air outlet net 11 flows through the air compressor cabin 4 from the frequency converter cabin 3 and then enters the intercooler cabin 5, and finally is discharged outward through the air outlet 9. The control panel 14 is used to control the operation of the electrical structure inside the entire box body. The air compressor cabin 4 inside the box body shell 1 is fixedly connected with an intercooling component 12 through a bracket.

[0022] In this embodiment, the interior of the box housing 1 can be designed with a three-layer structure. At the same time, water-cooled heat dissipation is adopted, which has a higher efficiency than air heat dissipation. In addition to the traditional heat dissipation of the frequency converter and the secondary compressed gas, an additional primary compressed gas heat dissipation and motor cooling gas heat dissipation are added, further reducing the outlet gas temperature, increasing the compressor efficiency, reducing the cooling gas discharge port, lowering the surrounding environment temperature and the risk of dust entering the compressor, and ensuring heat dissipation while reducing the failure rate of water ingress; at the same time, a gas cooling and recovery system is adopted, which not only ensures that the outlet gas temperature is low enough, but also ensures that there is no external heat dissipation port, improves the compressor efficiency, and the electrical components inside the external hanging cabin 13 can prevent the risk of water ingress and facilitate later maintenance.

[0023] The technical solution of the present invention is elaborated in detail: The air suspension compressor needs a frequency converter to control the speed during use. Due to its secondary compression characteristics, the temperature of the gas pressurized by it will be extremely high. The air suspension compressor also requires a part of the gas to dissipate heat inside its motor; 1. To achieve the heat dissipation of the compression of the air suspension centrifugal fan, the present invention has made four groups of heat dissipation water circuits: 1) the heat dissipation water circuit of the frequency converter, 2) the heat dissipation water circuit of the primary compressed air intercooler, 3) the heat dissipation water circuit of the secondary compressed air intercooler, and 4) the heat dissipation water circuit of the motor cooling air intercooler; 2. To prevent electric shock caused by water leakage, the box body design follows three parts. The upper part is the electrical part, that is, the position of the frequency converter structure. The middle part is the compressor part, that is, the position of the compressor structure. The lower part is the placement position of the intercooler; Drainage holes are reserved at the bottom; 3. The gas flow direction follows the air filter - frequency converter cabin - compressor cabin; The gas flows into the frequency converter cabin from the air filter, cools the frequency converter and then enters the compressor intake cabin, and is inhaled by the compressor after being mixed with the motor cooling gas; A part is discharged through the secondary compression through the main air duct, and a part returns to the compressor intake cabin after cooling the compressor and passing through the intercooler; 4. All electrical components (circuit boards, circuit breakers, etc.) that do not require water-cooled heat dissipation are uniformly placed in the external hanging cabin to reduce the risk of water ingress and the difficulty of maintenance; 5. To prevent the risk of water ingress, all electronic valves of the vent valve type are uniformly externally hung outside the cabin, and an external hanging structure or external hanging holes are set.

[0024] The main advantages of this application of the present invention: 1. Water-cooled heat dissipation has a higher efficiency than air heat dissipation. In addition to the traditional heat dissipation of the frequency converter and the secondary compressed gas, an additional primary compressed gas heat dissipation and motor cooling gas heat dissipation are added, further reducing the outlet gas temperature, increasing the compressor efficiency, reducing the cooling gas discharge port, lowering the surrounding environment temperature and the risk of dust entering the compressor; 2. The three-layer structure design ensures heat dissipation while reducing the failure rate of water ingress; 3. The gas cooling and recovery system not only ensures that the outlet gas temperature is low enough, but also ensures that there is no external heat dissipation port, improving the compressor efficiency; 4. The electrical components are placed in the external hanging cabin, eliminating the risk of water ingress and facilitating later maintenance.

[0025] The key points of the concept of this application: 1. Water-cooled heat dissipation, with external cooling water connected, improving the overall heat dissipation efficiency.

[0026] 2. Three-layer structure design reduces the risk of water ingress, while ensuring air intake for heat dissipation of the frequency converter, increasing the heat dissipation efficiency.

[0027] 3. The gas cooling and recovery system improves the heat dissipation efficiency.

[0028] 4. Electrical components are placed in the external hanging compartment, eliminating the risk of water ingress and facilitating later maintenance. Example 2

[0029] As Figures 4 to 7 shown, on the basis of Example 1, a water-cooled structure 6 is further proposed, which includes a water inlet diversion pipe 61 fixedly connected to one end of a water inlet pipe 7, a water outlet diversion pipe 62 fixedly connected to one end of a water outlet pipe 8, a water inlet shunt pipe 63 fixedly connected to the other end of the water inlet diversion pipe 61, a water outlet shunt pipe 64 fixedly connected to the other end of the water outlet diversion pipe 62, a cooling pipe 65 and a strengthening pipe 66 are respectively connected between the water inlet shunt pipe 63 and the water outlet shunt pipe 64, an opening and closing assembly 67 is arranged inside the water inlet shunt pipe 63 corresponding to one end of the strengthening pipe 66, and a check valve 68 is fixedly connected to the inside of the water outlet shunt pipe 64 corresponding to one end of the strengthening pipe 66.

[0030] The opening and closing assembly 67 includes a housing 671 fixedly connected to the inner wall surface of the water inlet shunt pipe 63 near one end of the strengthening pipe 66. Inside the housing 671, a first cylindrical hole 672 and a second cylindrical hole 673 are respectively opened. A movable plate 674 is arranged inside the second cylindrical hole 673 near the first cylindrical hole 672. A concave groove 675 is opened on the inner wall surface of the housing 671, a tension spring 676 is arranged inside the concave groove 675, a communication groove 677 is opened on the inner wall of the housing 671 corresponding to the inner side surface of the second cylindrical hole 673, and a convex ring 678 is fixedly connected to the outer surface of one side of the movable plate 674.

[0031] The number of the water inlet diversion pipe 61 and the water outlet diversion pipe 62 is one group in each of the frequency converter cabin 3, the air compressor cabin 4 and the intercooler cabin 5. The number of the water inlet shunt pipes 63 corresponding to one group of water inlet diversion pipes 61 and the number of the water outlet shunt pipes 64 corresponding to one group of water outlet diversion pipes 62 are both one group; the number of the cooling pipes 65 and the strengthening pipes 66 is several groups, and the cooling pipes 65 and the strengthening pipes 66 are distributed at intervals. The two ends of the strengthening pipes 66 and the cooling pipes 65 are respectively connected and communicated with the inside of one group of water inlet shunt pipes 63 and one group of water outlet shunt pipes 64; the housing 671 and the water inlet shunt pipe 63 are fixedly bonded with glue. The first cylindrical hole 672 and the second cylindrical hole 673 are both cylindrical hole structures, and the diameter of the second cylindrical hole 673 is larger than that of the first cylindrical hole 672. The second cylindrical hole 673 is communicated with the first cylindrical hole 672, and the movable plate 674 slides back and forth along the axial length direction of the second cylindrical hole 673.

[0032] The axis of the tension spring 676 coincides with the axes of both the first cylindrical hole 672 and the second cylindrical hole 673. The number of the communication grooves 677 is several groups and they are distributed in an annular array. The axis line of the communication groove 677 is parallel to the axis line of the second cylindrical hole 673, and the height of the communication groove 677 is less than the height of the second cylindrical hole 673. The height of the movable plate 674 is less than the height of the second cylindrical hole 673; the height of the movable plate 674 is not greater than one-third of the height of the second cylindrical hole 673. The tension spring 676 is horizontally arranged, and the elastic ends of the tension spring 676 are fixedly connected to the outer shell 671 and the movable plate 674 respectively. The convex ring 678 is a circular ring structure that protrudes outward and is made of rubber material.

[0033] In this embodiment, water can be effectively and evenly distributed and flow in the three-layer cabins inside the box body shell 1, so as to effectively and quickly cool each structure in each area. At the same time, the flow rate of the water flowing into the water distribution pipe 63 can be adjusted according to the needs of users, so as to form a better cooling effect.

[0034] In summary, the working principle of the present invention is as follows: During the use process, cold water is injected through the water inlet pipe 7, so that the cold water enters the water cooling structure 6 to cool the three parts of the frequency converter cabin 3, the air compressor cabin 4 and the intercooler cabin 5 inside the box body shell 1. At the same time, the filtered air is inhaled into the interior of the frequency converter cabin 3 through the air filter 10, blown into the interior of the frequency converter cabin 3 from the air outlet net 11 through the air guide channel, flows from the interior of the frequency converter cabin 3 into the interior of the air compressor cabin 4, and then flows into the interior of the intercooler cabin 5 through the interior of the air compressor cabin 4 and is discharged outwards from the opening of the air outlet 9, so as to control the temperature of the structures that need to be cooled inside the box body shell 1. At the same time, in the form of an external hanging cabin 13, some structures that do not need to be cooled are externally hung, will not contact the cooling system inside the box body shell 1, and there is no risk of water ingress, and it is convenient for subsequent maintenance work; During the above cooling use process, cold water is injected through the water inlet pipe 7. The cold water flows from the water inlet pipe 7 into the interior of the water inlet diversion pipe 61, flows from the water inlet diversion pipe 61 into the interior of the water distribution pipe 63, flows from the water distribution pipe 63 into the interior of the cooling pipe 65, flows from the cooling pipe 65 into the interior of the water outlet distribution pipe 64, flows into the opening of the water outlet pipe 8 from the water outlet diversion pipe 62 and then circulates and flows into the interior of the water inlet pipe 7 again. During the whole cooling process, the wind flows in from the air filter 10 and blows out from the air outlet 9, so as to carry out efficient cooling; During the above cooling process, when the temperature of the internal structure of the box body shell 1 increases to a relatively high level, the flow rate of the water flow in the water inlet pipe 7 is increased, so that the water flow pressure flowing into the internal part of the water inlet shunt pipe 63 from the water inlet diversion pipe 61 increases. During the process of increasing pressure, the water flow will impact the movable plate 674. When the water flow pressure is relatively high, the movable plate 674 will move in a direction away from the first columnar hole 672. At this time, the tension spring 676 will be stretched by a certain distance. When the movable plate 674 moves to about the middle position of the communication groove 677, the water flow will flow into the internal part of the second columnar hole 673 from the first columnar hole 672, and at the same time, it will flow into one end of the strengthening pipe 66 through the communication groove 677. The other end of the strengthening pipe 66 flows into the internal part of the water outlet shunt pipe 64 through the one-way valve 68. Thus, when the heat dissipation of the cooling pipe 65 is not sufficient, the two ends of the strengthening pipe 66 can form a water flow passage with the water inlet shunt pipe 63 and the water outlet shunt pipe 64 respectively through the impact of the water flow. At this time, the heat dissipation effect inside the box body shell 1 is the best.

[0035] It should be noted that the following are the explanations of relevant terms in this application: Frequency converter: The compressor frequency converter usually adopts the working mode of AC-DC-AC frequency converter. First, the alternating current is rectified into direct current, and then it is converted into alternating current with the required frequency through an inverter to control the rotation speed of the fan.

[0036] Air suspension compressor: It mainly uses an air bearing system. During operation, the compressor rotor rotates at a high speed to form a gas film between the bearings, realizing the suspension of the rotor, avoiding direct contact between mechanical components, and eliminating friction. The impeller is driven by a high-speed permanent magnet synchronous motor. The impeller inhales air to increase its kinetic energy, and converts the kinetic energy into pressure energy in the volute, and finally outputs it through the exhaust pipeline. It is usually two-stage, that is, the gas discharged from the first-stage volute is inhaled by the second-stage volute for secondary pressurization and then discharged to the exhaust pipeline.

[0037] Intercooler: The intercooler works based on the heat exchange principle. The high-temperature and high-pressure gas discharged from the compressor enters the intercooler, and through heat exchange with the phase-change coolant in the pipeline or the external cooling medium (such as water, etc.), the temperature of the high-temperature and high-pressure gas is reduced to become high-pressure gas with a lower temperature, and then it enters the subsequent pipeline.

[0038] Blow-off valve: One of the electronic valves, which contains electronic components.

[0039] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
