Description

Technical Field

[0001] This application relates to the field of fan technology, and in particular to a large screw compressor that can replace a centrifugal compressor. Background Technology

[0002] Compressed air is an indispensable part of modern industry, and is widely used in industries such as sewage treatment, petrochemicals, coal mining, machinery, food, medical, electronics, textiles, and packaging materials. There are many types of compressors on the market, and screw blowers are the main equipment for air supply.

[0003] An energy-saving screw blower device mentioned in an existing Chinese patent (authorization announcement number: CN219932454U) includes a housing and a cover plate. A disassembly assembly is provided between the housing and the cover plate. A screw blower body is fixedly connected to the bottom inner wall of the housing. A frequency converter is fixedly connected to the screw blower body. An air outlet pipe is fixedly connected to the top of the screw blower body, and a flange is fixedly connected to the front side of the screw blower body. This utility model has a reasonable structural design, which can effectively seal the housing, preventing noise generated under high-speed airflow due to gaps, thus effectively avoiding noise pollution. Furthermore, the sealed design allows for efficient heat dissipation of the screw blower body, enabling normal operation. It also facilitates the disassembly and assembly of the cover plate and the screw blower body for regular inspection and maintenance of the screw blower body.

[0004] When used, screw compressors are used for air extraction and compression. The compressed air is then used in industries such as petrochemicals, coal mining, machinery, food, medical, electronics, textiles, and packaging materials. While this facilitates the use of screw compressors, the aforementioned devices only dissipate heat from the screw compressor through heat sinks. The heat dissipation effect is relatively limited, which can easily lead to overheating of the screw compressor. This can affect the operating performance and service life of the screw compressor, making it inconvenient to use. Utility Model Content

[0005] The purpose of this application is to address the problem that heat dissipation through heat sinks is limited, which can easily lead to overheating of the screw compressor, affecting its performance and lifespan, and making it inconvenient to use. This application provides a large screw compressor as an alternative to centrifuges.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A large screw compressor as an alternative to a centrifuge includes a cabinet with two symmetrical doors. A fixing block is fixed inside the cabinet, and the screw compressor body is fixed on the fixing block. An air outlet pipe is fixed to one end of the screw compressor body, and an air inlet pipe is fixed to the end of the screw compressor body away from the air outlet pipe. An air inlet is provided on the cabinet. A heat-conducting plate is fixed on the screw compressor body, and heat sinks are fixed on the heat-conducting plate and arranged in an array. A heat dissipation vent is provided on the cabinet corresponding to the position of the heat sinks. A heat dissipation box is fixed to one end of the cabinet, and a heat dissipation mechanism is provided between the heat dissipation box and the cabinet.

[0008] By adopting the above technical solution and through the heat dissipation mechanism, the heat dissipation effect of the screw compressor can be improved, the situation of excessively high operating temperature of the screw compressor can be reduced, the impact on operating performance and service life can be reduced, and the stepped heat dissipation can be facilitated, thus facilitating energy use.

[0009] Furthermore, the heat dissipation mechanism includes a ventilation pipe fixed to one end of the heat dissipation box, a heat dissipation pipe fixed to the end of the heat dissipation box away from the ventilation pipe, the heat dissipation pipe extending into the cabinet body and corresponding to the heat sink and the screw motor body, the heat dissipation pipe being horn-shaped, and a heat dissipation component being provided inside the heat dissipation box.

[0010] By adopting the above technical solution, and with the cooperation of heat dissipation components, the heat dissipation pipe blows air to dissipate heat from the heat sink and the screw compressor body. The heat dissipation pipe is horn-shaped to increase the heat dissipation area, and the air flow rate is increased by the fan to improve the heat dissipation effect.

[0011] Furthermore, the heat dissipation component includes a motor fixed inside the heat dissipation box, the output end of the motor is fixed with fan blades and distributed in an array, the fan blades correspond to the heat dissipation pipes, and a control component is provided between the cabinet and the motor.

[0012] By adopting the above technical solution, the motor drives the fan blades to rotate and generate airflow, which facilitates heat dissipation.

[0013] Furthermore, the control components include a controller fixed to the cabinet door, a temperature controller fixed to the screw compressor body, the controller being electrically connected to a temperature sensor, and the motor being electrically connected to the controller; the motor is a variable frequency motor.

[0014] By adopting the above technical solution, the controller controls the motor to drive the fan blades to rotate. The motor is a variable frequency motor, which makes it easy to adjust the rotation speed of the motor according to the temperature, facilitates energy use, and facilitates heat dissipation.

[0015] Furthermore, filters are fixed inside both the ventilation duct and the heat dissipation vent.

[0016] By adopting the above technical solution, the filter screen filters and blocks the incoming air, reducing the entry of dust.

[0017] Furthermore, a filter box is fixed to one end of the cabinet, and filter plate one and filter plate two are installed inside the filter box. Filter plate two is located on the side of filter plate one. A fixing pipe is fixed on the filter box, and filter plate one corresponds to the air inlet pipe.

[0018] By adopting the above technical solution, the incoming air passes through filter plate one and filter plate two. Filter plate one filters and blocks large particles in the air, while filter plate two filters fine particles, which facilitates the use of the screw compressor.

[0019] Furthermore, activated carbon is provided inside the filter plate two.

[0020] By adopting the above technical solution, activated carbon is installed inside the filter plate 2, which facilitates the filtration of irritating gases and reduces damage to the equipment.

[0021] Furthermore, the upper ends of both filter plate one and filter plate two extend out of the filter box, and the filter box is fixed to filter plate one and filter plate two by bolts.

[0022] By adopting the above technical solution, when replacement is needed, simply loosen the bolts on the filter box to release the restriction on filter plate one or filter plate two, remove it for replacement, and then reset it, making it convenient for staff to replace.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. When the screw compressor is in use, the motor drives the fan blades to generate airflow. This airflow passes through the cooling pipes to cool the heat sink and the screw compressor body. The cooling pipes are funnel-shaped to increase the heat dissipation area. The fan increases the airflow speed to further improve the cooling effect. Simultaneously, a temperature sensor monitors the operating temperature of the screw compressor body. When the detected temperature exceeds the set temperature, feedback is sent to the controller. The controller then controls the motor to drive the fan blades to rotate. The motor is a variable frequency motor, which allows for adjustment of the motor speed according to the temperature level, facilitating energy use and heat dissipation. The cooling mechanism further enhances the cooling effect of the screw compressor, reducing the possibility of overheating and minimizing the impact on operating performance and service life. It also facilitates stepped cooling and energy conservation.

[0025] 2. When the screw compressor is in use, the extracted air enters the filter box through a fixed pipe. The incoming air passes through filter plate one and filter plate two. Filter plate one filters and blocks large particles in the air, while filter plate two filters fine particles. Filter plate two is equipped with activated carbon to facilitate the filtration of irritating gases and reduce damage to the equipment. When replacement is required, loosen the bolts on the filter box to release the restriction on filter plate one or filter plate two, remove it for replacement, and then reset it for easy replacement by the operator.

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses a large screw compressor as an alternative to a centrifuge.

[0035] Reference Figure 1 and Figure 2 A large screw compressor as an alternative to a centrifuge includes a cabinet 1 with two symmetrical cabinet doors 2. A fixing block 4 is fixed inside the cabinet 1, and a screw compressor body 3 is fixed on the fixing block 4. An air outlet pipe 6 is fixed to one end of the screw compressor body 3, and an air inlet pipe 5 is fixed to the other end of the screw compressor body 3 away from the air outlet pipe 6. An air inlet is provided on the cabinet 1. A heat-conducting plate 7 is fixed on the screw compressor body 3, and heat dissipation fins 8 are fixed on the heat-conducting plate 7 and arranged in an array. A heat dissipation vent is provided on the cabinet 1 corresponding to the position of the heat dissipation fins 8. A heat dissipation box 9 is fixed to one end of the cabinet 1, and a heat dissipation mechanism is provided between the heat dissipation box 9 and the cabinet 1.

[0036] When using the screw compressor, the operator connects the screw compressor's inlet pipe 5 to the sealed equipment that needs compression, compressing the air inside the equipment. The air is then discharged through the outlet pipe 6. During operation, the heat is dissipated through the heat-conducting fins 7 and dissipated through the heat sinks 8 in contact with the air. This cooling mechanism improves the screw compressor's heat dissipation effect, reduces the possibility of excessively high operating temperatures, minimizes the impact on operating performance and service life, facilitates stepped heat dissipation, and promotes energy efficiency.

[0037] Reference Figures 3-5 The heat dissipation mechanism includes a ventilation pipe 10 fixed to one end of the heat dissipation box 9, and a heat dissipation pipe 11 fixed to the end of the heat dissipation box 9 away from the ventilation pipe 10. The heat dissipation pipe 11 extends into the cabinet 1 and corresponds to the heat sink 8 and the screw compressor body 3. The heat dissipation pipe 11 is horn-shaped. A heat dissipation assembly is installed inside the heat dissipation box 9. The heat dissipation assembly includes a motor 12 fixed inside the heat dissipation box 9. Fan blades 13 are fixed to the output end of the motor 12 and are arranged in an array. The fan blades 13 correspond to the heat dissipation pipe 11. A control component is installed between the cabinet 1 and the motor 12. The control component includes a controller 14 fixed to the cabinet door 2, a temperature controller 14 fixed to the screw compressor body 3, the controller 14 being electrically connected to a temperature sensor 15, and the motor 12 being electrically connected to the controller 14. The motor 12 is a variable frequency motor 12. Filters 20 are fixed inside both the ventilation pipe 10 and the heat dissipation port.

[0038] When the screw compressor is in use, the motor 12 is started, which drives the fan blades 13 to rotate and generate airflow. The airflow blows through the heat dissipation pipe 11 to the heat sink 8 and the screw compressor body 3 for cooling. The heat dissipation pipe 11 is horn-shaped to increase the heat dissipation area. The fan increases the airflow speed to improve the cooling effect. When the air enters the cabinet 1 through the ventilation pipe 10, the filter screen 20 filters and blocks the incoming air to reduce dust entry. At the same time, the temperature sensor 15 monitors the operating temperature of the screw compressor body 3. When the detected temperature exceeds the set temperature, it is fed back to the controller 14. The controller 14 controls the motor 12 to drive the fan blades 13 to rotate. The motor 12 is a variable frequency motor, which can adjust the rotation speed of the motor 12 according to the temperature, which is convenient for energy use and heat dissipation. The heat dissipation mechanism improves the heat dissipation effect of the screw compressor, reduces the occurrence of excessively high operating temperature of the screw compressor, reduces the impact on operating performance and service life, facilitates stepped heat dissipation, and facilitates energy use.

[0039] Reference Figure 4 and Figure 5A filter box 16 is fixed to one end of the cabinet 1. Filter plate 18 and filter plate 19 are installed inside the filter box 16. Filter plate 19 is located on the side of filter plate 18. A fixing pipe 17 is fixed to the filter box 16. Filter plate 18 corresponds to the air inlet pipe 5. Activated carbon is installed inside filter plate 19. The upper ends of both filter plate 18 and filter plate 19 extend out of the filter box 16, and the filter box 16 is fixed to both filter plate 18 and filter plate 19 with bolts.

[0040] When the screw compressor is in use, the drawn air enters the filter box 16 through the fixed pipe 17. The incoming air passes through filter plate 18 and filter plate 19. Filter plate 18 filters and blocks large particles in the air, while filter plate 19 filters fine particles. Filter plate 19 is equipped with activated carbon to facilitate the filtration of irritating gases and reduce damage to the equipment. When replacement is required, the bolts on the filter box 16 are loosened to release the restriction on filter plate 18 or filter plate 19, and the filter plate is removed for replacement. Then, the filter box is reset for easy replacement by the operator.

[0041] The implementation principle of this embodiment of a large screw compressor that replaces centrifuge is as follows: When the screw compressor is in use, the operator connects the air inlet pipe 5 of the screw compressor to the sealed equipment that needs to be compressed, compresses the air inside the equipment, and discharges the air through the air outlet pipe 6. During operation, the heat is discharged through the heat conduction plate 7 and dissipated through the heat sink 8 in contact with the air.

[0042] When the screw compressor is in use, the motor 12 is started, and the motor 12 drives the fan blades 13 to rotate and generate airflow. The airflow blows through the heat dissipation pipe 11 to the heat sink 8 and the screw compressor body 3 for heat dissipation. The heat dissipation pipe 11 is horn-shaped to increase the heat dissipation area. The fan increases the airflow speed to improve the heat dissipation effect. When the air enters the cabinet 1 through the ventilation pipe 10, the filter screen 20 filters and blocks the incoming air to reduce the entry of dust. At the same time, the temperature sensor 15 monitors the operating temperature of the screw compressor body 3. When the detected temperature exceeds the set temperature, it is fed back to the controller 14. The controller 14 controls the motor 12 to drive the fan blades 13 to rotate. The motor 12 is a variable frequency motor, which can adjust the rotation speed of the motor 12 according to the temperature, which is convenient for energy use and heat dissipation.

[0043] When the screw compressor is in use, the drawn air enters the filter box 16 through the fixed pipe 17. The incoming air passes through filter plate 18 and filter plate 19. Filter plate 18 filters and blocks large particles in the air, while filter plate 19 filters fine particles. Filter plate 19 is equipped with activated carbon to facilitate the filtration of irritating gases and reduce damage to the equipment. When replacement is required, the bolts on the filter box 16 are loosened to release the restriction on filter plate 18 or filter plate 19, and the filter plate is removed for replacement. Then, the filter box is reset for easy replacement by the operator.
