Description

Technical Field

[0001] This utility model relates to the technical field of protective auxiliary equipment for high-speed and high-pressure blowers, and in particular to a sound insulation and flow-slowing module for the protection of high-pressure integrated blowers. Background Technology

[0002] High-speed, high-pressure blowers are used in the field of wastewater treatment. During the operation of the blower, it is necessary to draw in sufficient air from the outside, filter the air to reduce the dust content, and work around the clock. The high-frequency aerodynamic noise is relatively large, which can cause great damage to on-site personnel.

[0003] Therefore, to keep the noise level within a reasonable range, factories often use soundproof enclosures and high-pressure blowers together. During operation, in order to ensure the heat dissipation and air circulation required for the blower to work properly, ventilation windows must be installed in the soundproof enclosure. When the airflow passes through the ventilation windows, it will generate violent airflow impact and vortex phenomena.

[0004] This unstable airflow causes the ventilation window structure to vibrate, which in turn excites the surrounding air to vibrate, thus generating additional noise. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a sound-insulating and flow-slowing module for the protection of high-pressure integrated blowers.

[0006] The technical solution of this utility model is achieved through the following scheme: a high-pressure integrated blower protection sound insulation and flow slowing module, including a sound insulation box and a blower. The sound insulation box includes a blower compartment and a control compartment. Several second sound-absorbing and flow-slowing cotton boards are laid in the inner cavity of the blower compartment. A filter and ventilation door is provided oppositely on the end face of the blower compartment away from the control compartment. The blower is placed in the blower compartment. A labyrinth-type noise reduction and flow slowing module is installed on the side of the filter and ventilation door near the inner cavity of the blower compartment. The labyrinth-type noise reduction and flow slowing module is directly opposite the filter and ventilation door. The control compartment is connected to the blower compartment through a wiring port.

[0007] Through the above technical solutions, the airflow channel is optimized by the labyrinth-type noise reduction and flow-slowing module, reducing the noise generated by airflow impact and eddies. Moreover, when the airflow is flowing, the sound waves are constantly interfered with and reflected by the wall, and some of the sound wave energy is consumed, further reducing the outward propagation of noise. In addition, the synergistic filter ventilation door not only ensures the normal ventilation needs of the blower during operation, but the labyrinth structure can also buffer and guide the airflow, achieving the dual effect of smooth airflow and noise reduction. Combined with several second sound-absorbing and flow-slowing cotton boards, the noise generated during the operation of the blower is effectively absorbed and blocked, reducing the propagation of noise to the outside world.

[0008] Preferably, the filter ventilation door includes a support door and a filter ventilation window. The support door has an installation groove adapted to the filter ventilation window. A primary filter cotton is installed inside the filter ventilation window. The filter ventilation window is detachably installed in the installation groove. The bottom surface of the installation groove has several air filtering holes. A medium-efficiency filter is installed inside the installation groove.

[0009] Preferably, one side of the filter ventilation window is connected to the support door via several hinges, the other side of the filter ventilation window is provided with a latch, and the support door is provided with a locking groove that matches the latch.

[0010] Through the above technical solutions, the filter ventilation window and the support door fit tightly together to form a good sealing effect. First, the primary filter cotton effectively intercepts larger particles and debris in the air. Then, the medium-efficiency filter and air filter holes perform secondary filtration of the air, intercepting small particles and impurities. The incoming air is also initially dispersed and buffered, so that the airflow enters the fan compartment more evenly and smoothly, reducing the noise generated by airflow turbulence and further improving the noise reduction performance of the equipment.

[0011] Preferably, the labyrinthine noise reduction and flow control module includes a baffle plate and a first sound-absorbing and flow control cotton plate, wherein the first sound-absorbing and flow control cotton plate is screwed onto the baffle plate, and the baffle plate is upside down installed on the filter ventilation door.

[0012] Preferably, the support plate of the baffle protection plate has several air outlet holes, and the first sound-absorbing and slow-flow cotton plate is directly opposite the filter ventilation door.

[0013] Preferably, both the first sound-absorbing and slow-flowing cotton board and the second sound-absorbing and slow-flowing cotton board are provided with a slow-flowing surface.

[0014] Through the above technical solutions, the flow direction and path of the airflow are changed by the baffle plate, causing the airflow to be deflected multiple times as it passes through. During the deflection process, the airflow collides with the first sound-absorbing and flow-slowing cotton plate, and the sound energy is continuously dissipated, thereby effectively reducing the noise generated by the airflow and achieving noise reduction. At the same time, the flow-slowing surface can slow down the airflow speed, allowing the airflow to pass through more smoothly and reducing the noise generated by the turbulent airflow. The baffle plate can also protect the blower and filter ventilation door to a certain extent, preventing the airflow from blowing directly on them. In addition, the multiple air outlets not only ensure the ventilation volume, but also further disperse and buffer the airflow, allowing the airflow to enter the blower compartment more evenly.

[0015] In summary, this utility model has the following beneficial effects: 1. This utility model optimizes the airflow channel through a labyrinth-type noise reduction and flow-slowing module, reducing noise generated by airflow impact and eddies. Moreover, as the airflow flows, sound waves are continuously interfered with and reflected by the wall surface, and some sound wave energy is consumed, further reducing the outward propagation of noise. In addition, the synergistic filter ventilation door not only ensures the normal ventilation needs of the blower during operation, but the labyrinth structure can also buffer and guide the airflow, achieving the dual effect of smooth airflow and noise reduction. Combined with several second sound-absorbing and flow-slowing cotton boards, it effectively absorbs and blocks the noise generated during the operation of the blower, reducing the propagation of noise to the outside world.

[0016] 2. The air exchange window and the support door fit tightly together to form a good sealing effect. The primary filter cotton effectively intercepts larger particles and other impurities in the air. Then, the medium-efficiency filter and air filter holes perform secondary filtration of the air, intercepting small particles and impurities. The incoming air is also initially dispersed and buffered, so that the airflow enters the fan compartment more evenly and smoothly, reducing the noise generated by airflow turbulence and further improving the noise reduction performance of the equipment.

[0017] 3. By altering the airflow direction and path through the baffle plate, the airflow undergoes multiple deflections as it passes through. During these deflections, the airflow collides with the first sound-absorbing and flow-damping cotton plate, continuously dissipating sound energy and effectively reducing noise generated by the airflow. Simultaneously, the flow-damping surface slows the airflow speed, allowing it to pass more smoothly and reducing noise caused by turbulent airflow. The baffle plate also provides a degree of protection for the blower and filter / exchange valve, preventing direct airflow. Furthermore, the multiple air outlets ensure adequate ventilation while further dispersing and buffering the airflow, allowing it to enter the blower compartment more evenly.

[0020] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Sound insulation and flow damping modules for high-pressure integrated blower protection, such as... Figures 1-6 As shown, the system includes a soundproof enclosure and a blower 3. The soundproof enclosure includes a blower compartment 5 and a control compartment 4. Several second sound-absorbing and flow-regulating cotton boards 6 are laid inside the blower compartment 5. A filter ventilation door 1 is provided opposite to the blower compartment 4 on the end face of the blower compartment 5. The blower 3 is placed inside the blower compartment 5. A labyrinth-type noise reduction and flow-regulating module 2 is installed on the side of the filter ventilation door 1 near the inner cavity of the blower compartment 5. The labyrinth-type noise reduction and flow-regulating module 2 is directly opposite the filter ventilation door 1. The control compartment 4 is connected to the blower compartment 5 through a wiring port 8. The two filter ventilation doors 1 are mounted on the end face of the blower compartment 5 by hinges that allow them to rotate relative to each other. While ensuring clean and efficient air intake, the noise level of the entire machine is controlled below 80 decibels. The coverage area of ​​the labyrinth-type noise reduction and flow control module 2 is consistent with the air exchange area of ​​the filter and air exchange valve 1, ensuring full coverage. The labyrinth-type noise reduction and flow control module 2 is screwed to the side of the filter and air exchange valve 1 and located in the inner cavity of the fan chamber 5. The airflow entering from the filter and air exchange valve 1 will be processed by the labyrinth-type noise reduction and flow control module 2, and there will be no situation where some airflow bypasses the noise reduction module and directly enters the fan chamber 5, ensuring the comprehensiveness and stability of the noise reduction effect and avoiding noise leakage caused by untreated local airflow.

[0023] Multiple second sound-absorbing and buffering cotton boards 6 absorb and buffer the noise generated by the blower 3 in the blower chamber 5 during operation, reduce the reflection and propagation of sound waves, and reduce the superposition effect of noise in the blower chamber 5.

[0024] The filter ventilation door 1 includes a support door 11 and a filter ventilation window 12. The support door 11 has an installation groove 102 that matches the filter ventilation window 12. A primary filter cotton 105 is installed inside the filter ventilation window 12. The filter ventilation window 12 is detachably installed in the installation groove 102. The bottom surface of the installation groove 102 has several air filter holes 103. A medium-efficiency filter 104 is installed inside the installation groove 102. The medium-efficiency filter 104 is snapped into the protruding part of the installation groove 102, and its air outlet abuts against the multiple air filter holes 103. Next, the air exchange window 12 has louvers on one side and a snap-fit ​​groove on the other side, where the primary filter cotton 105 is snapped in. The air exchange window 12 faces the labyrinth-type noise reduction and flow control module 2 and is completely covered by it. The air filter hole 103 is equipped with a filter screen. The medium-efficiency filter 104 and the air filter hole 103 work together to filter the primary filter cotton 105 in the air exchange window 12 for double filtration. The air filter hole 103 further improves the air filtration state and serves as the final filtration protection to effectively prevent the escape of impurities generated when the medium-efficiency filter 104 leaks.

[0025] One side of the filter ventilation window 12 is connected to the support door 11 by several hinges, and the other side of the filter ventilation window 12 is provided with a latch 9. The support door 11 is provided with a locking groove that matches the latch 9. The filter ventilation window 12 can be opened and closed freely like a door, which is simple and convenient to operate. When it is necessary to check, clean or replace the primary filter cotton 105, the medium-efficiency filter 104 and the filter screen inside the air filter hole 103, it is only necessary to open the filter ventilation window 12. No complicated tools and operating procedures are required, which improves work efficiency. When the filter ventilation window 12 is closed, the latch 9 and the locking groove can be used to firmly fix the filter ventilation window 12 to the support door 11, preventing the filter ventilation window 12 from being accidentally opened due to vibration or other reasons during the operation of the blower 3, ensuring the safety and stability of the equipment, and avoiding the impact on the normal operation of the equipment due to air leakage or foreign objects entering.

[0026] The labyrinth-style noise reduction and flow-slowing module 2 includes a baffle plate 21 and a first sound-absorbing and flow-slowing cotton plate 22. The first sound-absorbing and flow-slowing cotton plate 22 is screwed onto the baffle plate 21. The baffle plate 21 is installed upside down on the filter ventilation door 1. The support plate 10 of the baffle plate 21 has several air outlet holes 101. The baffle plate 21 includes a baffle plate and several support plates 10. Screws are provided at the four corners of the baffle plate and the middle of the four corners. The first sound-absorbing and flow-slowing cotton plate 22... The screw is screwed to it, and multiple support plates 10 are all set on the same side of the mounting surface of the first sound-absorbing and slow-flow cotton plate 22. The support plate 10 and the baffle plate are integrally set. The first sound-absorbing and slow-flow cotton plate 22 faces the filter and ventilation door 1, is upside down on the support door 11, and is screwed to it. Multiple square air outlet holes 101 are opened on the baffle plate. Under the premise of ensuring ventilation volume, the airflow is reasonably dispersed and buffered, reducing the generation of airflow turbulence and eddies, and reducing the additional noise caused by airflow turbulence.

[0027] The baffle plate slows down the intake airflow. The noise generated by the blower 3 running in the blower compartment 5 is reflected by the baffle plate and the air inlet of the filter ventilation window 12 and the noise intensity is reduced by the sound-absorbing cotton. When the sound absorption effect of the first sound-absorbing and slow-flow cotton plate 22 decreases due to long-term use or needs to be cleaned, it can be easily removed from the baffle protection plate 21 for replacement or cleaning, which reduces maintenance costs and difficulty.

[0028] Both the first sound-absorbing and slow-flow cotton board 22 and the second sound-absorbing and slow-flow cotton board 6 are provided with a slow-flow surface 7. The sound-absorbing cotton surfaces inside the first sound-absorbing and slow-flow cotton board 22 and the second sound-absorbing and slow-flow cotton board 6 are provided with interlaced flow channels. When the airflow impacts the cotton board, the pores inside the cotton board will generate resistance to the airflow, thereby slowing down the airflow speed. The lower airflow speed can reduce the friction and collision between the airflow and the inner wall and components of the equipment, reduce the noise generated by the turbulent airflow, and also help reduce the impact force of the airflow on the equipment, protect the internal components of the equipment, and guide the airflow through the slow-flow surface 7 to guide the airflow to be more evenly distributed, avoid the airflow being too concentrated in some areas or the formation of eddies, and improve the operating stability of the equipment.

[0029] Multiple second sound-absorbing and slow-flowing cotton boards 6 have the same structure as the first sound-absorbing and slow-flowing cotton board 22. They are all sound-absorbing cotton installed inside the sound cotton cover plate and the whole is fixed in position by studs and nuts.

[0030] The control compartment 4 is used to install the whole machine control system. The parts and equipment are all conventional models in the prior art. In addition, the circuit connection and communication connection are all conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification are prior art known to those skilled in the art.

[0031] Working principle: External air is drawn in by blower 3 and first passes through the filter ventilation window 12. Large dust particles are intercepted by the primary filter cotton 105 inside the filter ventilation window 12. It is further filtered by the medium-efficiency filter 104 with the mounting groove 102 and the air filter hole 103 to intercept small dust particles, achieving a dual purification and dust removal effect. It also passes through the baffle plate 21 and the slow flow surface 7 of the first sound-absorbing and slow flow cotton plate 22 to slow the flow and reduce impact. The noise generated during the operation of blower 3 will spread to the outside. When the sound wave reaches the air intake channel between the labyrinth-type noise reduction and flow control module 2 and the filter ventilation door 1, it will bounce back and forth between the baffle plate 21 of the labyrinth-type noise reduction and flow control module 2 and the support door 11 of the filter ventilation door 1. The sound-absorbing cotton of the first sound-absorbing and flow control cotton plate 22 absorbs part of the sound wave, thereby reducing the sound wave that propagates to the outside of the cabinet and achieving the purpose of reducing noise.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
