Description

Technical Field

[0001] This utility model relates to the field of chiller technology, specifically a dustproof industrial chiller. Background Technology

[0002] A chiller is a water-cooling device that provides constant temperature, constant flow, and constant pressure cooling. The principle of a chiller is to inject a certain amount of water into the machine's internal water tank, where the chiller's refrigeration system cools the water. Then, an internal water pump injects the chilled water into the equipment that needs cooling. The chilled water carries away the heat from inside the machine, and the hot water is returned to the water tank for further cooling. This cycle of cooling and exchange achieves the purpose of cooling the equipment. In the treatment of industrial VOCs (volatile organic compounds), chillers are used to cool waste gas with high water content, thereby achieving the effect of removing water and water mist from the waste gas.

[0003] In industry, air-cooled chillers are commonly used, which involve installing a fan to introduce natural air into the chiller. However, due to the presence of dust and other impurities in the air, dust is carried into the chiller's interior during airflow, leading to dust accumulation. Therefore, a dust filter needs to be installed on the outside of the chiller. Existing chiller dust filters are not very effective at preventing dust and are inconvenient to clean and use. To address these issues, the inventor proposes a dustproof industrial chiller to solve these problems. Utility Model Content

[0004] In order to solve the problems of poor dust prevention effect and inconvenience in cleaning and use of existing dustproof screens for water chillers, the purpose of this utility model is to provide a dustproof industrial water chiller.

[0006] Preferably, the air inlet has multiple annularly distributed sliding grooves, and the limiting rods are slidably engaged in the corresponding sliding grooves. The upper and lower ends of the multiple sliding grooves are provided with limiting grooves, and the upper and lower surfaces of one end of the multiple limiting rods are fixedly installed with locking blocks, and the locking blocks are slidably engaged in the corresponding limiting grooves.

[0007] Preferably, a gear ring is rotatably installed inside the air inlet, a first gear is fixedly installed at the bottom end of the rotating shaft and meshes with the gear ring, a plurality of second gears distributed in a ring are rotatably installed inside the air inlet, a tooth groove is opened on one side of the plurality of limiting rods and the second gear meshes with the corresponding tooth groove, and a third gear is fixedly installed at the top of the plurality of second gears and meshes with the gear ring.

[0008] Preferably, a pull ring is fixedly installed on the upper surface of the dustproof net, and a rotation direction mark is fixedly provided on the upper surface of the protective cover.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. In this utility model, by detachably installing a dustproof net inside the air inlet, it is possible to prevent dust and other impurities from entering the interior of the chiller through the air inlet during air intake. The protective cover can prevent large particles of impurities from falling on the dustproof net and causing damage to the dustproof net, thereby achieving double protection and making the dustproof net easy to clean, replace and use.

[0011] 2. In this utility model, by setting a limiting rod, while the protective cover drives the rotating shaft to rotate to open or close, a series of transmission components can drive the limiting rod to slide and extend in the corresponding groove, thereby limiting and releasing the dustproof net, thus achieving the purpose of facilitating the installation and disassembly of the dustproof net.

[0022] Example: Figure 1-7 As shown, this utility model provides a dustproof industrial chiller, including a housing 1, which is the housing of an existing industrial chiller. An air inlet 2 is fixedly installed at the top of the housing 1. A fan is installed inside the air inlet 2 to introduce natural air into the chiller. A dustproof screen 6 is detachably installed inside the air inlet 2 to prevent dust and other impurities from entering the chiller during air intake. A rotating shaft 8 is rotatably installed on one side of the top of the air inlet 2. A protective cover 3 is fixedly installed at the top of the rotating shaft 8 to prevent large particles from falling onto the dustproof screen 6 and damaging it, thus achieving double protection. A fastening bolt 4 is inserted through one side of the protective cover 3, and the bottom end of the fastening bolt 4 can be threaded into the top of the air inlet 2. The fastening bolt 4 is used to limit and fix the protective cover 3. Multiple limiting rods 10 are slidably inserted in the air inlet 2 in a ring. The limiting rods 10 can limit and fix the dustproof net 6. When there is a lot of dust and other impurities adhering to the dustproof net 6, first remove the fastening bolt 4, and rotate the protective cover 3 180 degrees around the center of the rotating shaft 8 to open it. Then, let the limiting rods 10 slide into the air inlet 2 to release the dustproof net 6 from the limit. Then, the dustproof net 6 can be taken out for cleaning or replacement, thus achieving the purpose of making the dustproof net 6 easy to clean, replace and use.

[0023] The air inlet 2 has multiple annularly distributed sliding grooves 16, and the limiting rods 10 are slidably locked in the corresponding sliding grooves 16. The upper and lower ends of the multiple sliding grooves 16 are provided with limiting grooves 17. The upper and lower surfaces of one end of the multiple limiting rods 10 are fixedly installed with locking blocks 11, and the locking blocks 11 are slidably locked in the corresponding limiting grooves 17.

[0024] By adopting the above technical solution, the limiting rod 10 slides in the corresponding slide groove 16, and at the same time, the limiting rod 10 drives the locking block 11 to slide in the corresponding limiting groove 17. The limiting groove 17 can limit the sliding stroke of the limiting rod 10 to prevent the limiting rod 10 from sliding out of the slide groove 16.

[0025] A gear ring 5 is rotatably installed inside the air inlet 2. A first gear 9 is fixedly installed at the bottom end of the rotating shaft 8 and meshes with the gear ring 5. Multiple second gears 13 are rotatably installed in the air inlet 2 in a ring. A toothed groove 12 is opened on one side of multiple limit rods 10 and meshes with the corresponding toothed groove 12. A third gear 14 is fixedly installed at the top of multiple second gears 13 and meshes with the gear ring 5.

[0026] By adopting the above technical solution, the protective cover 3 drives the rotating shaft 8 to rotate, the rotating shaft 8 drives the first gear 9 to rotate, the first gear 9 drives the gear ring 5 to rotate, the gear ring 5 drives the third gear 14 to rotate, the third gear 14 drives the second gear 13 to rotate, and the second gear 13 drives the limiting rod 10 to slide in the slide groove 16 through the tooth groove 12.

[0027] A pull ring 7 is fixedly installed on the upper surface of the dustproof net 6, and a rotation direction mark 15 is fixedly installed on the upper surface of the protective cover 3.

[0028] By adopting the above technical solution, the pull ring 7 makes it easy to remove the dustproof net 6. Users can rotate to open the protective cover 3 according to the rotation direction mark 15, and close the protective cover 3 simply by reversing the operation.

[0029] Working Principle: In use, this utility model allows natural air to be introduced into the machine through the air inlet 2. The dustproof net 6 inside the air inlet 2 prevents dust and other impurities from entering the chiller's interior through the air inlet 2 during air intake. The protective cover 3 prevents large particles of impurities from falling onto the dustproof net 6 and causing damage, thus achieving double protection. When there is a lot of dust and other impurities adhering to the dustproof net 6, first remove the fastening bolt 4. The user can rotate the protective cover 3 180 degrees around the center of the rotating shaft 8 according to the rotation direction mark 15. The rotating shaft 8 drives the first gear 9 to rotate, the first gear 9 drives the gear ring 5 to rotate, the gear ring 5 drives the third gear 14 to rotate, and the third gear 14 drives the second gear 13 to rotate. The second gear 13 drives the limiting rod 10 to slide into the slide groove 16 through the tooth groove 12, so that the dustproof net 6 is released from the limit. Then, the dustproof net 6 can be taken out through the pull ring 7 for cleaning or replacement, thus achieving the purpose of making the dustproof net 6 easy to clean, replace and use.
