Description

Technical Field

[0001] This utility model relates to the field of noise control technology, specifically to a soundproof box. Background Technology

[0002] In the machinery manufacturing and brewing industries, pneumatic conveying systems and their power equipment are frequently used. Examples include air compressors and screw pumps in the machinery manufacturing industry, and compressed air power systems (i.e., power equipment) such as disc blowers and Roots blowers in the brewing industry. The power equipment in pneumatic conveying systems generates significant noise during operation, and the resulting booming sound can damage the hearing of operators and even interfere with the normal operation of the equipment. Therefore, soundproof enclosures are needed to reduce noise pollution, provide a safe working environment, and extend the lifespan of the power equipment by reducing vibration and echo.

[0003] Traditional soundproof enclosures have the following problems.

[0004] The first type uses sheet metal louvers to provide heat dissipation in the soundproof box. If the temperature is too high or the fan's cooling impeller stops working, and personnel do not notice it in time, the motor will burn out, causing the entire air delivery system to fail and resulting in greater losses.

[0005] The second type is that the soundproof box uses an unreasonable soundproof box structure, which has a poor noise absorption effect and cannot effectively reduce the noise level to below 65 decibels. Utility Model Content

[0006] To address the above problems, this utility model provides a soundproof box, which at least solves the problem of untimely heat dissipation inside the soundproof box in the prior art.

[0007] This utility model provides a soundproof enclosure for use in the power equipment of a pneumatic conveying system, including an enclosure body and an exhaust fan. The enclosure body is fitted over the power equipment, and the inner wall of the enclosure body is provided with a sound insulation layer. The exhaust fan is located on the side wall of the enclosure body, facing the power equipment, and is communicatively connected to the power equipment through the control panel of the pneumatic conveying system.

[0008] By setting the exhaust fan and power equipment to be linked and controlled in the above way, when the power equipment is working, the exhaust fan opposite to the power equipment can be controlled to simultaneously deliver air to the power equipment to cool it down. This helps to ensure the sound insulation effect of the soundproof box while timely heat dissipation inside the soundproof box, thus improving the heat dissipation effect of the soundproof box.

[0009] Optionally, the soundproof enclosure also includes a filter assembly located on the side wall of the enclosure and opposite to the exhaust fan. The cross-sectional area of ​​the filter assembly is S, and the actual exhaust volume of the exhaust fan divided by S is less than or equal to 10 m / s.

[0010] By installing filter components opposite the exhaust fan on the side wall of the soundproof enclosure, airflow within the enclosure is ensured. This airflow carries heat from the power equipment inside the enclosure into the atmosphere, maintaining a consistent temperature between the inside and outside of the enclosure and preventing the motors of the power equipment from burning out due to overheating. Simultaneously, the actual airflow of the exhaust fan is matched to the filter components to prevent excessive noise inside the soundproof enclosure caused by excessive airflow from the exhaust fan.

[0011] Optionally, the enclosure includes multiple interconnected side panels and a top panel that matches the side panels. The side panels are spaced apart along the periphery of the power unit, and the top panel is spaced apart along the top of the power unit. The exhaust fan and filter assembly are both located on the side panels.

[0012] Through the above methods, there is a gap between the side panels and top panel of the enclosure and the power equipment, ensuring that a reasonable space is reserved inside the enclosure for airflow.

[0013] Optionally, the side panel includes a first side panel, a second side panel, a third side panel, and a fourth side panel arranged sequentially and forming a rectangle, with the exhaust fan located above the second side panel.

[0014] By using the above method, the side panels of the enclosure are formed into a rectangle, that is, the enclosure is rectangular, which saves the overall space occupied by the soundproof enclosure and is beneficial to manufacturing.

[0015] Optionally, an access door is provided on the first side panel.

[0016] The above methods can meet the maintenance needs of power equipment.

[0017] Optionally, a temperature sensor is installed inside the soundproof enclosure, and the temperature sensor is connected in communication with the control console.

[0018] By using the above methods, a temperature sensor is installed to monitor the temperature inside the soundproof enclosure in real time. When the temperature inside the enclosure is abnormal, a warning can be issued through the control panel, which makes it easier for operators to troubleshoot the cause of the temperature abnormality, avoid damage to the power equipment, and ensure the safe use of the power equipment.

[0019] Optionally, the side wall of the enclosure is provided with an air inlet and an air outlet. The air inlet is located on the third side panel, and the air outlet is located above the fourth side panel. The power equipment is connected to the air inlet and the air outlet through an air inlet pipe and an air outlet pipe, respectively.

[0020] In this way, the power equipment is connected to the air inlet and air outlet through the air inlet pipe and air outlet pipe respectively, ensuring the normal operation of the air delivery system.

[0021] Optionally, the air inlet is provided with an air inlet growth transition component, which passes through the third side plate and connects to the air inlet duct. The air outlet is provided with an air outlet growth transition component, which passes through the fourth side plate and connects to the air outlet duct.

[0022] By using the above methods, after the power equipment is covered by a soundproof box, an effective connection between the power equipment and the air inlet / outlet ducts can be ensured, enabling the air delivery system to work normally.

[0023] Optionally, the bottom of the side wall of the enclosure is made in contact with the ground via a silicone plate.

[0024] Through the above methods, the silicone sheet can undergo elastic deformation. Under the overall weight of the soundproof box, the noise transmission caused by uneven ground can be ignored, ensuring the sealing between the side wall of the box and the ground, which is conducive to ensuring the overall sound insulation effect of the soundproof box.

[0025] Optionally, the bottom of the power equipment is in contact with the ground via a shock-absorbing pad.

[0026] By using the above methods, direct contact between the power equipment and the ground can be avoided, reducing vibration transmission and noise pollution, while improving the stability and service life of the power equipment during operation. Attached Figure Description

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Figure 1 This is a structural schematic diagram of the soundproof box 100 in an embodiment of this utility model. It should be noted that... Figure 1 This is a front view. In this embodiment of the invention, the soundproof box 100 is applied to the power equipment 220 of the air conveying system 200 (e.g., Figure 1 As shown), for example in the brewing industry, a disc pneumatic system 200 includes a disc device 210 and a power device 220 that provides pneumatic conveying to the disc device 210, the power device 220 being a disc fan that provides positive pressure pneumatic conveying.

[0045] In the brewing industry, material (powder or granules) is conveyed using vacuum pumps for negative pressure conveying and pneumatic conveying, and the power source (i.e., power equipment 220) is a Roots blower.

[0046] Furthermore, Roots blowers offer high conveying efficiency and are relatively convenient. Additionally, the power equipment 220 may include a motor 221 connected to a disc blower or a Roots blower.

[0047] <Soundproof Box 100>

[0048] Figure 2 This is a right view of the soundproof box 100 in this embodiment of the utility model. (Reference) Figure 1 and Figure 2This utility model provides a soundproof enclosure 100, which includes a enclosure body 110 and an exhaust fan 120. The enclosure body 110 is fitted onto the outside of a power device 220, and the inner wall of the enclosure body 110 is provided with a sound insulation layer. The exhaust fan 120 is located on the side wall of the enclosure body 110 and faces the power device 220. The exhaust fan 120 is communicatively connected to the power device 220 through the control panel of the air delivery system 200, that is, the exhaust fan 120 can work synchronously with the power device 220 under the control of the control panel. For example, when the power device 220 is turned on, the exhaust fan 120 mounted on the soundproof enclosure 100 is turned on synchronously, and the impeller begins to rotate. When the power device 220 is turned off, the impeller of the exhaust fan 120 is stopped, that is, the exhaust fan 120 is turned off synchronously.

[0049] When the power unit 220 (i.e., disc blower or Roots blower) inside the soundproof box 100 is in operation, the corresponding motor 221 also continuously generates heat. The limited space inside the soundproof box 100 leads to poor air circulation, causing the internal temperature to rise continuously. Without human intervention or notice, this could eventually lead to the motor 221 burning out or even the power unit 220 in the air conveying system 200 becoming inoperable, resulting in significant losses.

[0050] By setting the exhaust fan 120 and the power equipment 220 to be linked and controlled in the above way, when the power equipment 220 is working, the exhaust fan 120 opposite to the power equipment 220 can be controlled to simultaneously supply air to cool the power equipment 220. This is beneficial to ensure the sound insulation effect of the soundproof box 100 while timely heat dissipation inside the soundproof box 100, thereby improving the heat dissipation effect of the soundproof box 100.

[0051] The components of the soundproof box 100 in this embodiment of the present invention will be described in detail below.

[0052] <Box 110>

[0053] like Figure 1 As shown, the enclosure 110 includes multiple interconnected side panels and a top plate 115 that matches the side panels. The side panels are spaced along the periphery of the power unit 220. The exhaust fan 120 and the filter assembly 130 are both located on the side panels. The top plate 115 is spaced along the top of the power unit 220. Both the side panels and the top plate 115 of the enclosure 110 are detachable. The base of the enclosure 110 has an integrated frame, which can be made of channel steel. The frame is located at the bottom of the soundproof enclosure 100 and can directly surround the power unit 220. The top plate 115 can be an independent top plate with a square tube structure.

[0054] In this way, there is a gap between the side panels and top panel 115 of the housing 110 and the power equipment 220, ensuring that there is enough space reserved inside the housing 110 for air circulation, avoiding the waste of cost and space caused by the excessive size of the housing 110, and ensuring that the size of the housing 110 is reasonable.

[0055] Figure 3 This is a left view of the soundproof box 100 in this embodiment of the present utility model. Figure 4 This is a rear view of the soundproof box 100 in this embodiment of the utility model. (In conjunction with...) Figure 1 and Figure 2 and refer to Figure 3 and Figure 4 The side panels may include a first side panel 111, a second side panel 112, a third side panel 113, and a fourth side panel 114 arranged sequentially and forming a rectangle. The exhaust fan 120 is located above the second side panel 112. Specifically, the four side panels may be configured as bent plates, working in conjunction with the top panel 115 to surround the five sides of the power equipment 220. Multiple square tubes may also be provided along the height of the enclosure 110. These square tubes connect the base of the enclosure 110 to the top panel 115, providing support for the four side walls and top of the soundproof enclosure 100, ensuring the overall stability of the soundproof enclosure 100. The square tubes can be bolted to the base and top panel 115, and the four side panels can also be bolted to the square tubes. This invention does not limit the connection method between the components constituting the enclosure 110.

[0056] The four side panels and the top panel 115 facing the power equipment 220 can be covered with composite sound insulation cotton. The composite sound insulation cotton includes sound-absorbing cotton with crests and troughs and sound-insulating cotton. The back of the sound insulation cotton is provided with adhesive for pasting. That is, the sound-absorbing cotton, sound-insulating cotton and adhesive are arranged in sequence to effectively control the noise level below 65 decibels, thereby ensuring the sound insulation effect of the soundproof box 100.

[0057] In this way, the side panels of the enclosure 110 are arranged in a rectangle, that is, the soundproof enclosure 100 as a whole is rectangular, which saves the overall space occupied by the soundproof enclosure 100 and is beneficial to manufacturing. At the same time, the various components that make up the enclosure 110 are easy to transport, the detachable structure makes the enclosure 110 easy to install, and the overall structure is simple, which helps to reduce costs.

[0058] Figure 5 This is a top view of the soundproof box 100 in this embodiment of the utility model. Figure 3 and Figure 5As shown, the side wall of the enclosure 110 is provided with an air inlet 230 and an air outlet 240. The air inlet 230 is located on the third side plate 113, and the air outlet 240 is located above the fourth side plate 114. The power unit 220 is connected to the air inlet 230 and the air outlet 240 through the air inlet pipe and the air outlet pipe, respectively. At this time, the noise generated by the soundproof box 100 mainly comes from the vibration of the motor 221 of the power unit 220 and the power unit 220 as a whole, as well as the sound of the impeller rotation of the power unit 220 (i.e., the disc blower or the Roots blower) in the air delivery system 200 (which is transmitted through the air).

[0059] Through the above methods, the power equipment 220 is connected to the air inlet 230 and the air outlet 240 via air inlet and outlet pipes respectively, ensuring the normal operation of the air delivery system 200. At the same time, the structure of the enclosure 110 is reasonably designed to reduce noise transmission and improve the standardization of the overall layout of the soundproof enclosure 100 and the air delivery system 200.

[0060] Continue to refer to Figure 3 and Figure 5 The air inlet 230 is provided with an air inlet growth transition piece 231, which passes through the third side plate 113 and is connected to the air inlet duct. The air outlet is provided with an air outlet growth transition piece 241, which passes through the fourth side plate 114 and is connected to the air outlet duct.

[0061] By using the above methods, after the power equipment 220 is covered by the soundproof box 100, the effective connection between the power equipment 220 and the air inlet / outlet duct can be ensured, so as to realize the normal operation of the air delivery system 200.

[0062] <Exhaust Fan 120>

[0063] like Figure 2 As shown, the exhaust fan 120 can be a high-powered cooling exhaust fan 120, and the noise level of the high-powered cooling exhaust fan 120 can be below 65 decibels. The high-powered cooling exhaust fan 120 can be installed on the upper part of the side wall of the cabinet 110 (e.g., Figure 1 Above the second side panel 112 in the soundproof box, and the height of the strong cooling fan 120 on the side wall can be higher than the normal height of the operator. When the soundproof box 100 is small, the strong cooling fan 120 is set on the side where the operator has less activity, so as to avoid interfering with the operator's normal activities.

[0064] <Filter Component 130>

[0065] like Figure 3As shown, the soundproof enclosure 100 also includes a filter assembly 130, which is located on the side wall of the enclosure 110 and is positioned opposite to the exhaust fan 120. The filter assembly 130 is selected according to the actual exhaust volume of the exhaust fan 120. Specifically, the cross-sectional area of ​​the filter assembly 130 is S, and the actual exhaust volume of the exhaust fan 120 divided by S is less than or equal to 10 m / s. The actual exhaust volume of the exhaust fan 120 varies depending on the type of power equipment 220. For example, when the power equipment 220 is a disc fan, the actual exhaust volume of the exhaust fan 120 is simply the exhaust volume of the exhaust fan 120. When the power equipment 220 is a Roots blower, the Roots blower can operate on both positive and negative pressure, therefore the actual exhaust volume of the exhaust fan 120 is the exhaust volume of the exhaust fan 120 plus the intake volume of the Roots blower.

[0066] Since the exhaust fan 120 and the filter assembly 130 are positioned opposite each other, the actual exhaust volume of the exhaust fan 120 is the same as the airflow through the filter assembly 130. Based on the airflow through the filter assembly 130 and the cross-sectional area S of the filter assembly 130, the cross-sectional air velocity of the filter assembly 130 can be calculated. By controlling the cross-sectional air velocity of the filter assembly 130 to be below 10 m / s, the appropriate filter assembly 130 is selected.

[0067] By means of the above method, a filter assembly 130 is installed on the side wall of the soundproof enclosure 100, opposite to the exhaust fan 120, to ensure airflow within the enclosure 110. This airflow carries the heat from the power equipment 220 inside the enclosure 110 into the atmosphere, ensuring a uniform temperature inside and outside the soundproof enclosure 100 and preventing the motor 221 of the power equipment 220 from burning out due to overheating. Simultaneously, the actual exhaust volume of the exhaust fan 120 is matched to the filter assembly 130 to prevent excessive noise inside the soundproof enclosure 100 due to excessive airflow from the exhaust fan 120.

[0068] like Figure 2 and Figure 3 As shown, the filter assembly 130 can be a filter screen, which can be configured with filter cotton, and the filter cotton has an IP rating of 65. Multiple filter screens can be provided; for example, in this embodiment of the invention, the number of filter screens is set to two, with one filter screen located on the fourth side plate 114 on the left side of the housing 110 (e.g., Figure 3 The filter screen in the middle is positioned opposite to the exhaust fan 120, and the other filter screen is located on the second side panel 112 on the right side of the housing 110, opposite to the filter screen on the left side (e.g., Figure 2 The filter screen in the middle is on the same side as the exhaust fan 120 on the right side of the housing 110. Setting multiple filters can further accelerate the airflow inside the housing 110.

[0069] <Inspection door 140>

[0070] like Figure 1As shown in the figure, a maintenance door 140 can be provided on the first side plate 111, that is, a maintenance door 140 is provided on the side of the box body 110 close to the motor 221 of the power equipment 220, meeting the maintenance requirements of the motor 221 of the power equipment 220.

[0071] <Temperature sensor>

[0072] As Figure 3 shown in the figure, a temperature sensor (not shown) is provided inside the sound insulation box 100. The temperature sensor is communicatively connected to the control console of the air delivery system 200, and the control console can be integrated on the disc device 210. Specifically, a temperature sensor is installed on the side of the sound insulation box 100 close to the motor 221 of the power equipment 220, and the probe of the temperature sensor is close to the internal space of the sound insulation box 100, capable of detecting the internal temperature of the sound insulation box 100 in real time. At the same time, the temperature sensor is communicatively connected to the PLC control cabinet of the disc device 210 to achieve linkage control. The temperature sensor is set with a maximum temperature. For example, the maximum temperature is 40 °C. When the internal air temperature of the sound insulation box 100 reaches 40 °C, the alarm system of the control cabinet can automatically alarm, facilitating the operator to check the reason for the excessive temperature inside the sound insulation box 100 (for example, the exhaust fan 120 is burned out or the impeller stops rotating), and avoiding greater losses caused by the burning of the motor 221 of the power equipment 220. At the same time, the maximum temperature set by the temperature sensor needs to be combined with the actual seasonal temperature and consider the maximum temperature required for the burning of the motor 221 of the power equipment 220, and the maximum temperature is determined after comprehensive consideration.

[0073] By the above method, setting the temperature sensor to monitor the temperature inside the sound insulation box 100 in real time can issue a warning through the control console when the temperature inside the sound insulation box 100 is abnormal, facilitating the operator to check the reason for the abnormal temperature and avoiding damage to the power equipment 220, ensuring the safe use of the power equipment 220.

[0074] <Silicone plate 116>

[0075] As Figure 1 and Figure 2 shown in the figure, the bottom of the side wall of the box body 110 abuts against the ground through the silicone plate 116. The silicone plate 116 can be pasted on the lower plane of the frame around the box body 110, that is, one side of the silicone plate 116 abuts against the frame at the bottom around the box body 110, and the other side contacts the ground. Glass glue can be filled between the lower plane of the frame around the box body 110 and the silicone plate 116 to ensure the overall sealing of the box body 110.

[0076] By the above method, the silicone plate 116 can produce elastic deformation. Under the action of the overall weight of the sound insulation box 100, the noise air transmission caused by the uneven ground can be ignored, ensuring the sealing between the side wall of the box body 110 and the ground, which is beneficial to ensuring the overall sound insulation effect of the sound insulation box 100.

[0077] like Figure 1 As shown, the bottom of the power unit 220 is in contact with the ground via a shock-absorbing pad (not shown).

[0078] By using the above methods, direct contact between the power equipment 220 and the ground is avoided, vibration transmission and noise pollution are reduced, and the stability and service life of the power equipment 220 during operation are improved.

[0079] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
