Description

Technical Field

[0001] The invention relates to the technical field of suspended blowers, and in particular to a noise-reducing air suspended centrifugal blower. Background Art

[0002] The air suspension centrifugal blower generates airflow through the rotating impeller, sucks in air and increases the airflow pressure through centrifugal force, thereby achieving air flow and pressurization. It can provide the required air supply for various industrial and commercial applications, and the noise reduction air suspension centrifugal blower adopts noise isolation and noise reduction design, and adopts sound-absorbing materials and soundproof covers to effectively reduce the noise level of the blower;

[0003] A patent with publication number CN219242246U discloses an air suspension centrifugal blower, including a base, a shell is fixedly connected to the upper end of the base, an air outlet is arranged at the upper center of the front end surface of the shell, a mounting frame is fixedly connected to the front end of the air outlet, a sealing gasket is fixedly connected to the front end of the mounting frame, connecting plates are fixedly connected to both sides of the lower end surface of the base, a plurality of first grooves are arranged front and back at the center of the lower end surfaces of the two connecting plates, shock-absorbing pads are fixedly connected to the lower ends of the two connecting plates, through holes are opened at corresponding positions on the upper end surfaces of the shock-absorbing pads at the lower ends of the plurality of first grooves, and the lower ends of the two shock-absorbing pads are fixedly connected to the base, and bamboo charcoal fillers are arranged on both sides of the motor, and the bamboo charcoal has good water absorption, which can absorb water vapor in the air to prevent water vapor from entering the motor, thereby reducing the influence of water vapor on the motor;

[0004] However, although the equipment in the comparative document can absorb water vapor in the air through the water absorption of bamboo charcoal, prevent water vapor from entering the motor and reduce the impact of water vapor on the motor, the saturation of bamboo charcoal's own adsorption is not taken into account. When bamboo charcoal is in a saturated state after long-term use, it cannot absorb moisture from the air in time. At this time, the entry of water vapor will cause water or moisture to accumulate inside the blower, thereby increasing the friction and resistance of the equipment, reducing its operating efficiency and even causing malfunctions. In addition, excessive water vapor entering the blower will also cause electrical components to become damp, thereby affecting their normal functions and even causing damage.

[0005] At the same time, bamboo charcoal generally absorbs water molecules through capillary force based on the presence of a large number of capillaries in its porous structure, and the small size and large specific surface area of ​​the capillary channels enhance the ability of this capillary absorption of water vapor. The air transported through the transport system generally still retains solid particles, and the high adsorption performance of bamboo charcoal depends largely on its large specific surface area. When solid particles enter and block these pores, it will seriously hinder the diffusion and adsorption of water molecules, thus causing damage to the structure of the bamboo charcoal, thereby affecting its adsorption performance;

[0006] In view of this, the present invention proposes a noise-reducing air suspension centrifugal blower to compensate for and improve the deficiencies of the prior art. Summary of the invention

[0007] In order to solve the above technical problems, the present invention provides a noise reduction air suspension centrifugal blower to solve the technical problems raised in the above background technology.

[0008] To achieve the above purpose, the technical solution adopted by the present invention is: a noise reduction air suspension centrifugal blower, comprising a support base, a high-speed motor is installed on the upper left side of the support base, a blower body is installed on the upper right side of the support base, a multi-layer air pretreatment mechanism is arranged on the front side wall of the support base, and a noise reduction air dehumidification mechanism is arranged on the air inlet end of the blower body;

[0009] The multi-level air pre-treatment mechanism is used to remove foreign particles in the conveyed air at multiple levels;

[0010] The noise reduction air dehumidification mechanism is used for processing water vapor in the conveyed air in a noise reduction manner.

[0011] Furthermore, the multi-level air pretreatment mechanism includes a limit frame fixedly connected to the front side wall of the support base, the limit frame is sleeved with a separation cylinder at one end away from the support base, the lower end inner wall of the separation cylinder is fixedly connected with a circular cross, the inner side wall of the circular cross is fixedly connected with an anti-blocking column, the upper surface of the separation cylinder is penetrated and connected with a ventilation pipe, the outer wall of the ventilation pipe at one end inside the separation cylinder is symmetrically fixedly connected with a fixing plate, the surface of the fixing plate is slidably connected with a sliding rod, the outer wall of the sliding rod is sleeved with a spring, and the end of the sliding rod away from the fixed plate is fixedly connected with a filter layer.

[0012] Furthermore, the upper half of the separation cylinder is cylindrical in shape as a whole, an air supply pipe is connected to an eccentric position of the outer wall of the upper half of the separation cylinder, the lower half of the separation cylinder is funnel-shaped as a whole, and guide grooves are evenly arranged on the inner wall of the lower half of the separation cylinder.

[0013] Furthermore, the anti-blocking column is in a cone shape as a whole, and the tip of the anti-blocking column is in the same vertical plane as the ventilation pipe.

[0014] Furthermore, the overall size of the filter layer is the same as the inner diameter of the ventilation pipe, the filter layer is located directly below the ventilation pipe as a whole, and the filter layer is made of cotton fiber material as a whole.

[0015] Furthermore, the noise reduction air dehumidification mechanism includes a dehumidification chamber connected to one side of the ventilation pipe, a telescopic rod group is fixedly connected to the top of the dehumidification chamber, a multi-section dehumidification plate is fixedly connected to the bottom of the telescopic rod group, an end of the multi-section dehumidification plate away from the telescopic rod group is slidably connected to an assembly cylinder, the assembly cylinder is connected to the ventilation pipe, a warning column is evenly slidably connected to the bottom wall of the dehumidification chamber, and a guide pipe is connected to the end of the dehumidification chamber away from the ventilation pipe.

[0016] Furthermore, arc grooves are opened through the assembly cylinder at the positions corresponding to the multi-section dehumidification plates, each of the multi-section dehumidification plates is composed of a combination of three circular dehumidification plates, the lowest circular dehumidification plate among the multi-section dehumidification plates is initially located inside the assembly cylinder, and the multi-section dehumidification plates are made of activated alumina material as a whole.

[0017] Furthermore, the guide tube as a whole is in the shape of a funnel which is narrow on the left and wide on the right, and the overall narrow-to-width ratio of the guide tube is 1:2. The telescopic rod component is divided into an outer ring sleeve and an inner ring column, and the inner side wall of the outer ring sleeve is fixedly connected with a ramp block, and an adaptation groove is provided at the position of the inner ring column corresponding to the ramp block.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The device uses the overall shape characteristics of the separation cylinder to remove large particle impurities from the transported air in the first step, and then installs a filter layer on the path that the air must pass through, and then removes small particle impurities from the transported air in the second step. When particles of different particle sizes are mixed together, larger particles will prevent smaller particles from being captured and removed. The device can avoid such mutual interference by dividing the steps into steps, so that each step can more effectively remove particles of the corresponding particle size, thereby improving the filtering effect. Compared with the prior art that directly concentrates the transported air through the filter device for purification, the filtering method of the device can prevent larger particles from directly contacting the filter, thereby reducing the burden on the filter, extending the service life of the filter, and preventing particles from directly contacting the filter to cause the filter to be blocked and damaged;

[0020] (2) The device can discharge the separated particles from the bottom of the separation cylinder in a centralized manner through the coordinated movement of the conical bottom of the separation cylinder and the reciprocating shaking of the filter layer, thereby reducing the cost of downtime maintenance and equipment operation for the staff and improving the reliability and stability of the filtration system. In addition, by discharging the particles in a centralized manner, the subsequent equipment can simplify the separate processing steps for the particles, reducing the complexity of the process and equipment. At the same time, by discharging certain valuable particles in a centralized manner, they can also be recycled, thereby avoiding the waste of resources.

[0021] Among them, since the inner wall of the lower half of the separation cylinder is evenly provided with guide grooves, and an anti-blocking column with an overall conical shape is installed at the position of the concentrated discharge of particle impurities at the bottom of the separation cylinder, and the conical structure has a good streamline shape, it can reduce the turbulence and resistance in the flow of fluid or gas, and the conical structure can concentrate the force acting on the structure to the vertex or the bottom to form a more concentrated stress distribution, thereby guiding the flow direction of the particles and preventing the particles from being concentrated and accumulated at the bottom of the separation cylinder;

[0022] (2) The device first installs multiple dehumidification plates on the path where air must flow to perform dehumidification operations. If water vapor in the air enters the blower body, it will accelerate the corrosion and wear of key components such as the internal impeller and bearings. Dehumidification treatment at the inlet of the blower body can effectively prevent water vapor from entering and thus extend the service life of the blower body. In addition, the dry air after dehumidification can reduce airflow resistance and improve the overall operating efficiency of the blower body.

[0023] Secondly, when the entire multi-section dehumidification board is in a saturated state after a long period of use, the staff can timely observe the sliding out of the warning column at the bottom of the dehumidification bin to determine whether the multi-section dehumidification board inside the dehumidification bin is in an adsorption saturation state and then replace the multi-section dehumidification board. By timely discovering the saturation state of the multi-section dehumidification board, the staff can take corresponding maintenance measures to avoid equipment failure and thus improve the reliability and stability of the equipment. In addition, by understanding the saturation time of the multi-section dehumidification board, the maintenance cycle can be adjusted according to the actual situation.

[0024] Among them, since the guide pipe is connected to the air inlet end of the blower body as a whole, and the guide pipe is in the shape of a funnel with a narrow left and a wide right shape, and the overall narrow-to-width ratio of the guide pipe is 1:2, when the subsequent airflow flows from the narrow opening to the wide opening of the guide pipe, the cross-sectional area will gradually expand. At this time, the air flow speed will be relatively reduced, thereby ensuring that the air flows stably to the inside of the blower body, and by reducing the gas flow rate through the expansion angle of the airflow outlet, the air flow direction can be maintained at a relatively stable level at the outlet, reducing changes in the gas flow direction, thereby guiding the airflow to smoothly enter the inside of the blower body and reducing the vortex noise caused by sudden contraction and direction changes of the airflow.

[0039] Specifically, the device first removes large particle impurities from the transported air through the overall shape characteristics of the separation cylinder 22, and then installs the filter layer 210 on the necessary path of air flow, and then removes small particle impurities from the transported air in the second step. When particles of different particle sizes are mixed together, larger particles will prevent smaller particles from being captured and removed. This mutual interference can be avoided by the step-by-step method of the device, so that each step can more effectively remove particles of corresponding particle sizes, thereby improving the filtering effect. Compared with the prior art that directly concentrates the transported air through the filter device for purification, the filtering method of the device can prevent larger particles from directly contacting the filter, thereby reducing the burden on the filter, extending the service life of the filter, and preventing particles from directly contacting the filter to cause the filter to be blocked and damaged;

[0040] Please refer to Figure 6 - Fig. 9As shown, the noise reduction air dehumidification mechanism 3 includes a dehumidification chamber 31 connected to one side of the ventilation pipe 26, a telescopic rod group 32 is fixedly connected to the top of the dehumidification chamber 31, and a multi-section dehumidification plate 33 is fixedly connected to the bottom of the telescopic rod group 32. An assembly cylinder 34 is slidably connected to the end of the multi-section dehumidification plate 33 away from the telescopic rod group 32, and the assembly cylinder 34 is connected to the ventilation pipe 26. A warning column 36 is evenly slidably connected to the bottom wall of the dehumidification chamber 31, and a guide pipe 37 is connected to the end of the dehumidification chamber 31 away from the ventilation pipe 26. The assembly cylinder 34 corresponds to the multi-section dehumidification plate 33. Arc grooves 35 are provided throughout the positions, each multi-section dehumidification plate 33 is composed of three circular dehumidification plates, the lowest circular dehumidification plates in the multi-section dehumidification plates 33 are initially located inside the assembly tube 34, the multi-section dehumidification plates 33 are made of activated alumina material, the guide tube 37 is in the shape of a funnel with a narrow left and a wide right, and the overall narrow-to-width ratio of the guide tube 37 is 1:2, the telescopic rod group 32 is divided into an outer ring sleeve and an inner ring column, and the inner side wall of the outer ring sleeve is fixedly connected with a ramp block, and an adapter groove is provided at the position of the inner ring column corresponding to the ramp block;

[0041] Specifically, the device first installs a multi-section dehumidification plate 33 on the necessary path of air flow to perform a dehumidification operation on the air. If the water vapor in the air enters the inside of the blower body 12, it will accelerate the corrosion and wear of its internal impellers, bearings and other key components. Dehumidification treatment at the inlet of the blower body 12 can effectively prevent the entry of water vapor and thus extend the service life of the blower body 12. The dry air after dehumidification can reduce the air flow resistance and improve the overall operating efficiency of the blower body 12. Secondly, since the multi-section dehumidification plate 33 itself has a saturated characteristic, it cannot be in a saturated state for a long time. In the moisture absorption treatment working state, the device slides the multi-section dehumidification plate 33 as a whole inside the dehumidification bin 31 through the telescopic rod group 32, so the unsaturated multi-section dehumidification plate 33 can be automatically replaced in time according to the gravity effect after the multi-section dehumidification plate 33 is saturated, thereby improving the problem of the long adsorption time of the multi-section dehumidification plate 33, and the automatic replacement of the new multi-section dehumidification plate 33 can ensure the continuous and effective dehumidification performance of the whole equipment, and can also reduce the labor intensity and maintenance cost of the staff, and avoid a series of complex operations that require manual participation in the equipment shutdown and then replacement;

[0042] The following are the complete usage steps and working principles of the above embodiment:

[0043] The working process of the device is as follows: before the staff uses the device for wind transportation, the existing gas transportation device should be connected to the air supply pipe on the outer wall of the separation cylinder 22, and then the staff starts the high-speed motor 11, and then continuously transports the airflow through the separation cylinder 22, the ventilation pipe 26 and the dehumidification chamber 31 to the inside of the blower body 12, and then transports it after being compressed by the blower body 12 as a whole;

[0044] The multi-level air pretreatment mechanism 2 for removing impurity particles in the conveying air at multiple levels is specifically used as follows:

[0045] like Figure 3 and Figure 4 As shown, since the upper half of the separation cylinder 22 is cylindrical as a whole and the lower half is funnel-shaped as a whole, and the air supply pipe is opened in the upper half of the separation cylinder 22, and the ventilation pipe 26 is inserted through the separation cylinder 22, when the existing gas conveying device inputs the airflow from the eccentric position of the air supply pipe into the separation cylinder 22, the flowing gas will be guided along the cylinder body of the cylindrical part of the separation cylinder 22 and the outer wall of the ventilation pipe 26, and a high-speed rotating airflow will be formed inside it. This rotating airflow is generated by the interaction of the momentum of the gas and the centrifugal force. When the gas rotates and flows through the lower half of the separation cylinder 22 to the bottom of the separation cylinder 22, the centrifugal force generated by the above-mentioned rotating airflow will throw the particles in the gas with a density greater than the gas itself to the inner wall of the separation cylinder 22. Once the particles come into contact with the inner wall of the separation cylinder 22, they will lose their inertial force and fall along the inclined inner wall of the separation cylinder 22 by the momentum of the inlet velocity and the downward gravity.

[0046] like Figure 4 As shown, when the airflow rotating in the separation cylinder 22 rotates down and reaches the bottom of the cone of the separation cylinder 22, the narrow conical bottom will guide the flowing gas to shrink inward and then move closer to the center of the separation cylinder 22. As the vertical tangential speed of the flowing gas continues to increase, when the airflow reaches the lower end of the cone, it will continue to make spiral motion from bottom to top in the separation cylinder 22 in the same rotation direction. Finally, the gas separated from the particles in the first step will continue to flow upward inside the separation cylinder 22, and then enter the ventilation pipe 26 and flow to the subsequent position. Since the filter layer 210 is located directly below the ventilation pipe 26 as a whole, and the overall size of the filter layer 210 is the same as the inner diameter of the ventilation pipe 26, and the filter layer 210 is composed of cotton fiber material as a whole, the cotton fiber itself has certain electrostatic properties and small pore size characteristics. Therefore, when the upwardly flowing gas passes through the filter layer 210, the filter layer 210 can absorb fine particles in the air through electrostatic force and its own size performance.

[0047] like Figure 5As shown, since the filter layer 210 and the fixed plate 27 are slidably connected by the slide rod 28, and the outer wall of the slide rod 28 is sleeved with a spring 29, when the upwardly flowing air passes through the position of the filter layer 210, the flowing air will act on the lower surface of the filter layer 210 and exert an upward force on it. At this time, the filter layer 210 will move upward along the inner wall of the fixed plate 27 under the limiting action of the slide rods 28 on both sides, and the spring 29 sleeved on the outer wall of the slide rod 28 will rely on its own elastic force to exert a downward force on the filter layer 210 again, thereby ensuring that the filter layer 210 moves up and down reciprocatingly along the inner wall of the fixed plate 27 during the air flow, thereby avoiding the situation where the filter layer 210 surface is adsorbed with some residual fine particles and causes blockage;

[0048] The noise reduction air dehumidification mechanism 3 for noise reduction treatment of water vapor in the conveying air is specifically used as follows:

[0049] like Figure 7 and Fig. 9 As shown, since the ventilation pipe 26 and the guide pipe 37 are connected through the assembly tube 34, and the lowest circular dehumidification plate in the multi-section dehumidification plate 33 is initially located inside the assembly tube 34, when the above-mentioned flowing air flows into the dehumidification chamber 31 through the ventilation pipe 26, the multi-section dehumidification plate 33 composed of activated alumina material as a whole will fully absorb the water vapor in the air and dehumidify it. Since each multi-section dehumidification plate 33 is composed of three circular dehumidification plates, and the multi-section dehumidification plates 33 are slidably connected to the dehumidification chamber 31 through the telescopic rod group 32, when the multi-section dehumidification plate 33 located inside the assembly tube 34 tends to be saturated after a long period of moisture absorption treatment, it will gradually move downward according to its own gravity, thereby moving the circular dehumidification plates that have not been subjected to moisture absorption treatment to the inside of the assembly tube 34. Since the telescopic rod group 32 is divided into an outer ring sleeve and The inner ring column and the inner side wall of the outer ring sleeve are fixedly connected with a ramp block, and an adapter groove is opened at the position of the inner ring column corresponding to the ramp block. Therefore, when the circular dehumidifier plate at the middle position of the multi-section dehumidifier plate 33 moves to the inside of the assembly cylinder 34, the ramp block is just inserted into the adapter groove, thereby maintaining the stability of the multi-section dehumidifier plate 33, thereby achieving the effect of automatic replacement of the dehumidifier plate, so that the inside of the assembly cylinder 34 is continuously in a state where water vapor can be adsorbed. In addition, when the entire multi-section dehumidifier plate 33 is in adsorption saturation, the dehumidifier plate at the bottom of the multi-section dehumidifier plate 33 will abut against the upper surface of the warning column 36, and then gradually squeeze the warning column 36 downward to make it slide out of the dehumidifier bin 31. The staff can judge whether the multi-section dehumidifier plate 33 inside the dehumidifier bin 31 is in an adsorption saturation state by observing the sliding out of the warning column 36 at the bottom of the dehumidifier bin 31, and then replace the multi-section dehumidifier plate 33 in time.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
