Description

Technical Field

[0001] The utility model relates to a box-type cover, in particular to a skid-mounted box-type sound insulation cover for a Roots blower. Background Art

[0002] In order to reduce the impact of the noise generated by the Roots blower during operation on the surrounding environment, a soundproof cover is usually installed on the outside of the blower. The noise source is enclosed in a relatively small space through the soundproof cover, reducing the noise radiated from the noise source to the surrounding environment. However, since most existing soundproof covers do not have windows such as inspection ports and operation status monitoring ports, it will cause inconvenience to maintenance and operation status monitoring.

[0003] Moreover, most of the existing sound insulation enclosures are relatively closed structures. After the blower has been running for a long time, the temperature inside the sound insulation enclosure will increase significantly, which will accelerate the aging of related components on the blower.

[0004] At the same time, most existing sound insulation enclosures need to be brought to the customer's site for assembly, which is limited by the conditions at the customer's site, such as small assembly space, harsh on-site environment, etc., which greatly reduces assembly efficiency and increases investment costs.

[0059] The connection between the longitudinal reinforcing support partition 205 and the top sound insulation board 1 can be a detachable connection or a non-detachable connection, such as welding, screwing, buckle fixing, lock fixing, etc., which can be selected according to specific usage requirements.

[0060] The connection method between the middle sound insulation board assembly 2 and the bottom support seat plate 3 can also be a detachable connection or a non-detachable connection, such as welding fixation, screw fixation, buckle fixation, lock fixation, etc., according to specific usage requirements, specific selection, wide application range and small limitations.

[0061] The longitudinal reinforcing support partitions 205 are used at the four corners of the soundproof enclosure to increase the overall impact resistance and structural stability of the soundproof enclosure, further ensuring that the soundproof enclosure can be used in harsh environments such as strong winds, rain, and snow.

[0062] The front sound insulation board 201 is composed of a front sound insulation board left section 20101 and a front sound insulation board right section 20102. The left end of the front sound insulation board left section 20101 is rotatably connected to the adjacent longitudinal reinforcing support partition 205, and the right end of the front sound insulation board right section 20102 is rotatably connected to the adjacent longitudinal reinforcing support partition 205.

[0063] The left section 20101 and the right section 20102 of the front sound insulation board can be controlled by locks to prevent relevant personnel from opening the cabinet door due to accidental operation and causing injuries.

[0064] The rear sound insulation panel 202 consists of a left section 20201 and a right section 20202. The upper end of the left section 20201 is abutted against the lower end of the top sound insulation panel 1. The lower end of the left section 20201 is fixedly connected to the upper end of the bottom support plate 3. The left end of the left section 20201 is fixedly connected to the adjacent longitudinal reinforcing support partition 205. An exhaust pipe fixing hole 10 is provided in the left section 20201. The interior of the exhaust pipe fixing hole 10 corresponds to the position of the air outlet box 19. The inner port of the air outlet box 19 is connected to the air outlet of the Roots blower 16. The outer port of the air outlet box 19 is connected to the corresponding external equipment via a connecting pipe 23 that passes through the exhaust pipe fixing hole 10.

[0065] The upper end of the right section 20202 of the rear sound insulation panel is detachably connected to the lower end of the top sound insulation panel 1. The lower end of the right section 20202 of the rear sound insulation panel is detachably connected to the upper end of the bottom support base plate 3. The left end of the right section 20202 of the rear sound insulation panel is in contact with the right end of the left section 20201 of the rear sound insulation panel. The right end of the right section 20202 of the rear sound insulation panel is in contact with the adjacent longitudinal reinforcing support partition 205. The interior of the right section 20202 of the rear sound insulation panel corresponds to the belt side of the motor 21. By opening the right section 20202 of the rear sound insulation panel, the motor 21 can be inspected or maintained.

[0066] The left sound insulation panel 203 comprises an upper portion 20301 and a lower portion 20302. The upper end 20301 of the upper portion 20301 abuts against the lower end of the top sound insulation panel 1. The left and right ends of the upper portion 20301 are fixedly connected to the adjacent longitudinal reinforcing support partition 205. A control panel window 11 is provided on the upper portion 20301. A control panel is mounted within the control panel window 11. The control panel includes operating controls for the internal Roots blower 16, controlling operations such as starting and stopping the Roots blower 16. Controls for other equipment within the sound insulation enclosure can be installed within the control panel window 11 as needed, facilitating comprehensive control of the blower unit by the operator.

[0067] The left sound insulation panel lower section 20302 is detachably connected and fixed between the left sound insulation panel upper section 20301 and the bottom support base plate 3. The left and right ends of the left sound insulation panel lower section 20302 are respectively abutted against the adjacent longitudinal reinforcing support partition 205. The left sound insulation panel lower section 20302 can be opened and closed between the left sound insulation panel upper section 20301 and the bottom support base plate 3. The interior of the left sound insulation panel lower section 20302 corresponds to the other side of the motor 21. The motor 21 primarily drives the Roots blower 16.

[0069] An oil level observation window is provided on the right sound insulation board 204. The interior of the oil level observation window 20401 corresponds to the position of the oil level window on the oil tank of the blower. Through the oil level observation window 20401, the amount of oil in the blower tank and the cleanliness of the oil can be checked in real time to avoid problems such as wear on the internal components of the blower due to insufficient oil or turbid oil.

[0070] Multiple ventilation grilles 6 are provided, one on each of the left section 20201 of the rear sound insulation panel, the right section 20202 of the rear sound insulation panel, the upper section 20301 of the left sound insulation panel, and the right sound insulation panel 204. These grilles 6 continuously circulate air in multiple directions within the sound insulation enclosure, thereby lowering the temperature within the enclosure and maintaining a suitable operating temperature, thereby ensuring long-term stable operation of the blower. Furthermore, the number of ventilation grilles 6 should not be excessive, as this would result in irregular air flow within the enclosure, creating turbulence and causing gas impact on relevant components within the enclosure. This would increase the noise level of the blower during operation and reduce the service life of relevant components within the enclosure due to the gas impact.

[0071] A first airflow noise reduction buffer box 24 is fixedly provided at the inner end of the left section 20201 of the rear sound insulation board at the position of the ventilation grille 6. A vent is provided at the upper end of the first airflow noise reduction buffer box 24. The vent is connected to the ventilation grille 6. A pressure relief valve 28 is connected to the connecting pipe 23 inside the sound insulation cover. When the exhaust pressure of the blower is too high, the pressure relief valve 28 plays a role in pressure relief protection to prevent the pressure in the pipe from being too high and causing an accident.

[0072] The pressure relief valve 28 is located inside the first airflow noise reduction buffer box 24, and the pressure relief hole on the pressure relief valve 28 is located at the lower end position inside the first airflow noise reduction buffer box 24. When the pressure relief valve 28 releases pressure, the pressure relief gas is discharged outward from the lower end position inside the first airflow noise reduction buffer box 24 through the upper end vent hole and the ventilation grille 6 in sequence.

[0073] According to actual installation requirements, the pressure relief valve 28 can also be placed inside the sound insulation enclosure at an outer position of the first airflow noise reduction buffer box 24, and vents are respectively provided at the upper and lower ends of the first airflow noise reduction buffer box 24. The vent at the upper end is connected to the ventilation grille 6, and the pressure relief hole on the pressure relief valve 28 is connected to the vent at the lower end of the first airflow noise reduction buffer box 24.

[0074] A third airflow noise reduction buffer box 26 is fixedly installed at the inner end of the right section 20202 of the rear sound insulation panel, located at the position of the ventilation grille 6. Ventilation holes are respectively provided at the upper and lower ends of the interior of the third airflow noise reduction buffer box 26. The vent holes at the upper end are interconnected with the ventilation grille 6, and the vent holes at the lower end are interconnected with the interior of the sound insulation enclosure. The interior and exterior of the sound insulation enclosure are interconnected through the lower and upper vent holes and the ventilation grille 6, thereby achieving air flow and reducing the temperature inside the sound insulation enclosure.

[0075] A second airflow noise reduction buffer box 25 is fixedly installed at the inner end of the upper portion 20301 of the left sound insulation panel, located at the position of the ventilation grille 6. Ventilation holes are respectively provided at the upper and lower ends of the second airflow noise reduction buffer box 25. The vent at the lower end communicates with the ventilation grille 6. An exhaust device 17 is fixedly installed outside the upper vent of the second airflow noise reduction buffer box 25. The exhaust device 17 includes an exhaust fan, dust collector, or other exhaust device. The exhaust port of the exhaust device 17 communicates with the upper vent of the second airflow noise reduction buffer box 25. When the exhaust device 17 is in operation, hot air inside the soundproof enclosure is discharged through the exhaust duct of the exhaust device 17, sequentially through the upper and lower vents of the second airflow noise reduction buffer box 25, and the ventilation grille 6, thereby cooling the interior of the soundproof enclosure.

[0076] A fourth airflow noise reduction buffer box 27 is fixedly installed at the inner end of the right sound insulation panel 204, at the position of the ventilation grille 6. Ventilation holes are respectively provided on the left and right sides of the fourth airflow noise reduction buffer box 27. The vent holes on the left side communicate with the ventilation grille 6, and the vent holes on the right side communicate with the interior of the soundproof enclosure. The left and right vent holes in the fourth airflow noise reduction buffer box 27 and the ventilation grille 6 connect the interior and exterior of the soundproof enclosure, thereby enabling air flow and reducing the temperature inside the soundproof enclosure.

[0077] Since the ventilation holes on the first airflow noise reduction buffer box 24, the second airflow noise reduction buffer box 25, the third airflow noise reduction buffer box 26, and the fourth airflow noise reduction buffer box 27 are respectively located on both sides of the corresponding airflow noise reduction buffer boxes, a Z-shaped airflow channel is formed inside the airflow noise reduction buffer box, which can buffer and reduce the noise of the airflow passing through, and avoid the problems of excessive noise, excessive impact force, etc. caused by the straight flow of the airflow.

[0078] Furthermore, by arranging the plurality of airflow noise reduction buffer boxes inside the soundproof enclosure, compared with most existing airflow noise reduction buffer boxes being arranged outside the soundproof enclosure, the overall footprint of the soundproof enclosure can be reduced, and collisions with the airflow noise reduction buffer boxes during the turnover of the soundproof enclosure can be avoided.

[0079] At the same time, since the airflow inside the soundproof enclosure has a certain temperature, the interior of the airflow noise reduction buffer box can be filled with flame retardant materials, such as polyurethane foam plastic, which can reduce the damage caused by high-temperature airflow to the airflow noise reduction buffer box.

[0080] The front and rear ends of the bottom support plate 3 are respectively provided with lifting grooves 4.
