Description

Technical Field

[0001] This utility model belongs to the field of air compressor hot oil recovery technology, specifically relating to an energy recovery type micro-oil screw air compressor waste heat recovery oil cooling device. Background Technology

[0002] In industrial production, screw air compressors are widely used as key equipment. However, screw air compressors generate a large amount of hot oil during operation. If this hot oil is not properly treated, it will not only waste energy but also adversely affect the performance and service life of the equipment. Therefore, the recovery and utilization of waste heat from screw air compressor hot oil is of significant practical importance.

[0003] Currently, some existing technologies exist for hot oil waste heat recovery systems. One such system, disclosed in CN115435496A, absorbs and stores excess heat generated during the heating of heat transfer oil in a car wash machine. The heating device can be shut off early, and the stored heat energy can be used to reheat the oil to maintain its temperature, effectively saving heat energy and achieving energy conservation and environmental protection. However, in practice, these systems primarily focus on heat recovery and reuse, often using the heat generated by the hot oil to heat equipment such as hot water tanks. A significant problem arises during the heating of hot water tanks: over time, dirt and impurities easily accumulate on the inner walls, and existing technologies lack convenient and effective methods for cleaning these inner walls. Failure to clean the inner walls of the hot water tank in a timely manner not only affects heat transfer efficiency and reduces waste heat recovery, but may also breed bacteria and other harmful substances, adversely affecting the equipment's operating environment and subsequent use. Utility Model Content

[0004] The purpose of this invention is to provide an energy recovery type micro-oil screw air compressor waste heat recovery oil cooling device to solve the technical problem that scale easily accumulates inside the water tank during the use of the recovery oil cooling device, affecting heat transfer.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An energy recovery type micro-oil screw air compressor waste heat recovery oil cooling device includes a cooling shell for hot oil recovery and cooling of the screw air compressor. A hot oil inlet pipe is installed on the top of one side of the cooling shell, and a cold oil drain pipe is installed on the bottom of one side of the cooling shell. The hot oil inlet pipe and the cold oil drain pipe are connected to each other through a connecting pipe. A cleaning component for cleaning the inner wall of the cooling shell is also installed inside the cooling shell.

[0007] As a further embodiment of this utility model, a water inlet pipe is installed on the top of one side of the cooling shell, and a drain pipe is installed on the bottom of the other side of the cooling shell.

[0008] As a further embodiment of this utility model, the cleaning component includes a rotatable drive frame, and the top and bottom of the drive frame are provided with cleaning structures for cleaning the inner wall of the cooling shell.

[0009] As a further embodiment of this invention, the cleaning assembly also includes a servo motor for driving the drive frame. The servo motor is fixedly mounted on the side of the cooling shell, and the output shaft of the servo motor is fixedly connected to the side of the drive frame.

[0010] As a further embodiment of this invention, a sealing gasket is provided on the side of the cooling shell at the position corresponding to the output shaft of the servo motor.

[0011] As a further embodiment of this utility model, a limiting slide rod is fixedly connected to the top and bottom of the side of the drive frame, and an annular slide groove matching the limiting slide rod is opened on the side of the inner wall of the cooling shell.

[0012] As a further embodiment of this utility model, elastic telescopic components are installed on both sides of the bottom of the cleaning structure. The elastic telescopic components include a mounting shell fixedly connected to the drive frame, an abutment spring fixedly connected to the inner wall of the mounting shell, a connecting slide column fixedly connected to the top of the abutment spring, and the top of the connecting slide column fixedly connected to the bottom of the cleaning structure.

[0013] As a further embodiment of this invention, a sealing ring is installed on the top of the mounting shell at the position corresponding to the connecting slide column.

[0014] Compared with existing technologies, the energy recovery type oil-cooled micro-oil screw air compressor waste heat recovery device provided by this utility model has the following beneficial effects:

[0015] 1. This device can effectively recover and cool hot oil through hot oil inlet pipe and cold oil outlet pipe, thereby improving energy efficiency; it is also equipped with a convenient cleaning component. The servo motor drives the drive frame to clean the inner wall of the cooling shell, and the elastic telescopic component ensures that the cleaning structure is always in close contact with the inner wall, enhancing the cleaning effect.

[0016] 2. Highly efficient waste heat recovery and cooling function: Hot oil generated by the screw air compressor is introduced into the cooling shell through the hot oil inlet pipe. Inside the cooling shell, the hot oil exchanges heat with water, cooling the oil and simultaneously transferring heat energy to the water, thus heating it. The cooled oil, after heat exchange, is then discharged through the cold oil drain pipe. The entire process achieves effective recovery and cooling of the hot oil from the screw air compressor, improving energy utilization efficiency and reducing energy waste.

[0017] 3. Convenient Internal Wall Cleaning Function: When the inside of the cooling shell needs cleaning, this invention features a unique cleaning component. Simply start the servo motor, which drives the drive frame to rotate, and the drive frame then drives the cleaning structure to thoroughly clean the inner wall of the cooling shell. This design makes cleaning operations simpler and faster, eliminating the need to disassemble the equipment or perform complex operations, greatly improving cleaning efficiency and reducing maintenance costs.

[0018] 4. Optimized Cleaning Effect: A key highlight of the cleaning assembly is its flexible telescopic component design. The spring within the telescopic component provides elasticity, ensuring the cleaning structure remains firmly pressed against the inner wall of the cooling housing. This tight contact guarantees sufficient friction when the cleaning structure contacts the inner wall, thus more effectively removing dirt and impurities. This significantly improves the cleaning effect on the cooling housing's inner wall, ensuring normal equipment operation and heat exchange efficiency.

[0019] 5. Excellent sealing and stability: A sealing gasket is installed on the side of the cooling shell, corresponding to the servo motor output shaft, effectively preventing liquid leakage inside the cooling shell and ensuring the device's sealing performance. Simultaneously, limit rods are fixedly connected to the top and bottom of the drive frame's side, and annular grooves matching the limit rods are formed on the side of the cooling shell's inner wall. This limiting design makes the drive frame more stable during rotation, reducing swaying and offset, and improving the overall operational reliability of the cleaning assembly.

For example, they can refer to a fixed connection, an integral connection, or a detachable connection; they can refer to the internal connection of two components; they can refer to a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present invention should be understood according to the specific circumstances.

[0038] See appendix Figure 1-5As shown in the figure, an embodiment of this utility model discloses an energy recovery type micro-oil screw air compressor waste heat recovery oil cooling device, including a cooling shell 1 for hot oil recovery and cooling of the screw air compressor. A hot oil inlet pipe 2 is installed on the top of one side of the cooling shell 1, and a cold oil drain pipe 3 is installed on the bottom of one side. The hot oil inlet pipe 2 and the cold oil drain pipe 3 are interconnected through a connecting pipe. In addition, a cleaning component 4 for cleaning the inner wall of the cooling shell 1 is also installed inside the cooling shell 1.

[0039] The above technical solution, through the cooperation of hot oil inlet pipe 2 and cold oil outlet pipe 3, realizes the entry and exit of hot oil in the screw air compressor, providing a basic channel for the recovery and cooling of hot oil; the setting of cleaning component 4 provides a guarantee for the subsequent cleaning of the inner wall of cooling shell 1, which helps to maintain the efficient operation of the device.

[0040] In order to replenish the water in the cooling shell 1 and better absorb the heat from the hot oil, a water inlet pipe 101 is installed on the top of one side of the cooling shell 1, and a drain pipe 1011 is installed on the bottom of the other side of the cooling shell 1. The water inlet pipe 101 allows water to be replenished in the cooling shell 1 in a timely manner, ensuring that there is enough water to absorb the heat released by the hot oil, improving the heat exchange efficiency, and thus achieving more effective waste heat recovery.

[0041] In order to drive the drive frame 401 in the cleaning assembly 4 to rotate and perform the cleaning action on the inner wall of the cooling shell 1, the cleaning assembly 4 includes a rotatable drive frame 401. The top and bottom of the drive frame 401 are provided with cleaning structures 4011 for cleaning the inner wall of the cooling shell 1. The rotatable drive frame 401 and the cleaning structures 4011 provide a structural basis for the comprehensive cleaning of the inner wall of the cooling shell 1. The rotation of the drive frame 401 can drive the cleaning structures 4011 to move on the inner wall of the cooling shell 1, thereby realizing the cleaning function.

[0042] To provide rotational power to the drive frame 401, the cleaning assembly 4 also includes a servo motor 402 for driving the drive frame 401. The servo motor 402 is fixedly mounted on the side of the cooling shell 1, and the output shaft of the servo motor 402 is fixedly connected to the side of the drive frame 401. The servo motor 402 can precisely control the rotational speed and angle of the drive frame 401, ensuring that the cleaning structure 4011 can clean the inner wall of the cooling shell 1 according to the predetermined trajectory and force, thereby improving the accuracy and reliability of the cleaning.

[0043] To prevent liquid inside the cooling shell 1 from leaking from the output shaft of the servo motor 402 and to ensure the airtightness of the device, a sealing gasket 4021 is provided on the side of the cooling shell 1 at the position corresponding to the output shaft of the servo motor 402. The sealing gasket 4021 effectively blocks the communication path between the liquid inside the cooling shell 1 and the outside, avoiding damage to the device and potential safety hazards caused by liquid leakage, and ensuring the normal operation of the device.

[0044] To ensure the stability of the drive frame 401 during rotation and prevent it from swaying or deviating, limiting slide rods 403 are fixedly connected to the top and bottom of the side of the drive frame 401. An annular groove 4031 matching the limiting slide rod 403 is provided on the side of the inner wall of the cooling shell 1. The cooperation between the limiting slide rod 403 and the annular groove 4031 plays a good role in limiting and guiding the rotation of the drive frame 401, so that the drive frame 401 can rotate on a stable trajectory, thereby ensuring the uniformity and effectiveness of the cleaning structure 4011 in cleaning the inner wall of the cooling shell 1.

[0045] To ensure that the cleaning structure 4011 remains in close contact with the inner wall of the cooling shell 1 and enhances the cleaning effect, elastic telescopic components 404 are installed on both sides of the bottom of the cleaning structure 4011. The elastic telescopic components 404 include a mounting shell 4041 fixedly connected to the drive frame 401, a contact spring 405 fixedly connected to the inner wall of the mounting shell 4041, a connecting slide post 4042 fixedly connected to the top of the contact spring 405, and the top of the connecting slide post 4042 fixedly connected to the bottom of the cleaning structure 4011. The elastic force of the contact spring 405 enables the connecting slide post 4042 to drive the cleaning structure 4011 to always be in close contact with the inner wall of the cooling shell 1. No matter what minor unevenness exists on the inner wall of the cooling shell 1, good contact between the cleaning structure 4011 and the inner wall can be guaranteed, thereby greatly improving the cleaning effect.

[0046] To prevent leakage of liquid or impurities inside the mounting housing 4041 and ensure the normal operation of the elastic telescopic component 404, a sealing ring 406 is installed on the top of the mounting housing 4041 and at the position corresponding to the connecting slide column 4042. The sealing ring 406 effectively prevents the leakage of substances inside the mounting housing 4041, avoids performance degradation or failure of the elastic telescopic component 404 due to leakage, and ensures that the cleaning structure 4011 can continuously and stably clean the inner wall of the cooling housing 1.

[0047] The above technical solution introduces hot oil from the screw air compressor into the cooling shell 1 through the hot oil inlet pipe 2. The hot oil exchanges heat with water within the cooling shell 1, heating the water and cooling the oil. The cooled oil is then discharged through the cold oil drain pipe 3, completing the recycling and cooling process of the screw air compressor's hot oil. When cleaning is required inside the cooling shell 1, the servo motor 402 is activated, driving the drive frame 401 to rotate. The limiting slide rod 403 on the drive frame 401 slides within the annular groove 4031, ensuring rotational stability. Simultaneously, under the elastic force of the abutment spring 405, the cleaning structure 4011 remains tightly pressed against the inner wall of the cooling shell 1. As the drive frame 401 rotates, the cleaning structure 4011 thoroughly cleans the inner wall of the cooling shell 1. The sealing ring 406 at the top of the mounting shell 4041 prevents internal leakage, ensuring a smooth cleaning process.

[0048] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
