Description

Technical Field

[0001] The utility model relates to the technical field of industrial refrigeration air conditioners, and more specifically, it relates to an industrial refrigeration air conditioner with an air purification function. Background Art

[0002] In the existing technology, in the industrial environment, the air often contains a large amount of dust, harmful gases and other pollutants. These pollutants will not only affect the health of the staff, but may also interfere with the normal operation of precision equipment. Without a primary filter and a HEPA high-efficiency filter, the particulate matter in the air cannot be effectively removed, resulting in a decline in indoor air quality.

[0003] Although there may be a filter installed inside the existing refrigeration air conditioner, the filter may shift or fall off during operation, resulting in air leakage or pollutants directly entering the system. It is impossible to achieve quick installation and disassembly, which increases the difficulty and time cost of maintaining and replacing the filter. The installation position of the filter may not be precise enough, affecting the filtering effect. In addition, in industrial scenarios with large vibrations or complex environments, this defect may lead to frequent adjustment or repair of the equipment, increasing the operating cost and downtime.

The polygonal-designed positioning groove 18 and positioning block 19 further enhance the accuracy and stability of positioning. During operation, the fixing mechanism and the limit control mechanism work together to ensure that the filter is firmly installed and does not loosen. If the filter needs to be replaced or cleaned, it can be unlocked by operating the limit control mechanism, and then the fixing mechanism can be disassembled to conveniently take out the filter. This design not only improves the efficiency of air purification and refrigeration but also facilitates daily maintenance and extends the service life of the equipment. The whole device integrates functions of air purification, cooling, and protection, is applicable to various industrial environments, and can effectively improve the air quality and temperature conditions of the workplace.

[0038] Please refer to Figures 5-7, as an implementation of the limit control mechanism: A limit control mechanism is provided on the outer wall of the fixed sleeve 11. The limit control mechanism includes a control sleeve 20, internal teeth 21, a screw 22, a gear 23, an annular groove 24, a limit block 25, and a limit groove 26. The control sleeve 20 is rotatably installed on the outer wall of the fixed sleeve 11. The internal teeth 21 are provided on the inner side of the control sleeve 20. Multiple groups of screws 22 are rotatably installed on the fixed sleeve 11 and are threadedly connected to the lock sleeve 14. The gear 23 is installed at the top of multiple groups of screws 22 and meshes with the internal teeth 21. The annular groove 24 is provided inside the control groove. Multiple groups of limit blocks 25 are slidably installed on the control sleeve 20 and the top ends thereof extend into the annular groove 24. Multiple groups of limit grooves 26 are distributed on the outer side of the fixed sleeve 11. By rotating the control sleeve 20, the movement of the internal teeth 21, the gear 23, and the screw 22 is driven, realizing the precise control of the lock sleeve 14. This design realizes the precise control of the position of the lock sleeve 14 and improves the reliability of the fixing mechanism.

[0039] A push spring 27 is connected between the inner walls of the annular groove 24 and multiple groups of limit blocks 25. The design of the annular groove 24 and the limit block 25 increases the flexibility of the operation. The push spring 27 ensures that the limit block 25 can automatically slide into the limit groove 26, further improving the reliability of the locking and the convenience of the operation.

[0040] More specifically, during operation, rotate the control sleeve 20. The internal teeth 21 on its inner side drive the meshing gear 23 to rotate. The gear 23 is installed at the top of the screw 22, so the screw 22 also rotates accordingly. The screw 22 is threadedly connected to the lock sleeve 14, so the lock sleeve 14 will move up and down. When the lock sleeve 14 moves down to a suitable position, multiple groups of limit blocks 25 slide into the limit grooves 26 on the outer side of the fixed sleeve 11 under the action of the push spring 27 to achieve locking. The annular groove 24 inside the control sleeve 20 provides space for the movement of the limit block 25, ensuring the smoothness of the operation.

[0041] In summary, when the overall device is in use or operation: The purification mechanism is installed on the mounting ring 1 through the front housing 2 and the rear housing 4 to form a complete air treatment unit. The suction fan 5 sucks the air to be treated from the rear housing 4. The air first passes through the primary filter 7 to remove larger particulate matters, and then passes through the HEPA high-efficiency filter 8 to filter out tiny particulate matters. The filtered air flows around the water-cooled pipe 6 for cooling treatment. Finally, the purified and cooled air is discharged from the front housing 2 by the exhaust fan 3. During the whole process, the activated carbon filter layer 17 can further adsorb harmful gases and odors in the air. The setting of the protective net 16 protects the fan and prevents foreign matters from entering. The fixing mechanism is used to install and fix the primary filter 7 and the HEPA high-efficiency filter 8. During installation, the filter is sleeved on the fixing rod 9, and the fixing sleeve 11 is sleeved on the top of the fixing rod 9. Multiple groups of clamping blocks 13 are rotatably installed in the installation groove 12 of the fixing sleeve 11 and can cooperate with the fixing groove 10 on the fixing rod 9. The lock sleeve 14 is sleeved on the outside of the fixing sleeve 11, and multiple groups of abutting wheels 15 thereon can push the clamping blocks 13 into the fixing groove 10 to achieve locking. The positioning groove 18 at the inner top of the fixing sleeve 11 cooperates with the positioning block 19 at the top of the fixing rod 9 to ensure accurate installation position. The polygonally designed positioning groove 18 and positioning block 19 further enhance the accuracy and stability of positioning. During operation, the fixing mechanism and the limit control mechanism work together to ensure that the filter is firmly installed and will not loosen. If the filter needs to be replaced or cleaned, it can be unlocked by operating the limit control mechanism, and then the fixing mechanism can be disassembled to conveniently take out the filter. This design not only improves the efficiency of air purification and refrigeration, but also facilitates daily maintenance and extends the service life of the device. The whole device integrates air purification, cooling and protection functions and is applicable to various industrial environments, which can effectively improve the air quality and temperature conditions of the workplace.

[0042] During operation, rotate the control sleeve 20, and the internal teeth 21 on its inner side drive the meshing gear 23 to rotate. The gear 23 is installed at the top of the screw rod 22, so the screw rod 22 also rotates accordingly. The screw rod 22 is threadedly connected to the lock sleeve 14, so the lock sleeve 14 will move up and down. When the lock sleeve 14 moves down to a suitable position, multiple groups of limit blocks 25 slide into the limit groove 26 on the outside of the fixing sleeve 11 under the action of the push spring 27 to achieve locking. The annular groove 24 inside the control sleeve 20 provides space for the movement of the limit blocks 25 to ensure the smoothness of the operation.
