Technical Field

[0001] This utility model relates to the field of cooling tower speed reducer technology, specifically to a cooling tower speed reducer exhaust device. Background Art

[0002] A cooling tower speed reducer is a mechanical device installed in a cooling tower system. It is mainly used to reduce the high-speed rotation of the motor to the low-speed rotation required by components such as fans or water pumps, so as to achieve reasonable energy conversion and stable operation of the equipment.

[0003] During operation, the gear oil or other lubricating media inside the speed reducer may generate steam or oil-gas mixture due to increased temperature. These gases usually need to be released through an exhaust device to maintain internal pressure balance and protect the seals. However, during the exhaust process, impurities in the gear oil or metal particles generated by wear can also enter the exhaust system with the hot gas and deposit in the pipes, which can easily cause blockages over time. Utility Model Content

[0004] The purpose of this utility model is to provide a cooling tower reducer exhaust device. By using this device, the problem of impurities in gear oil or metal particles generated by wear entering the exhaust system with the hot air during the exhaust process, which can easily cause blockage over a long period of time, is solved.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cooling tower reducer exhaust device, comprising an exhaust pipe fixedly connected to the top of the reducer exhaust port, a straight pipe movably disposed at the top of the exhaust pipe and a bent pipe movably disposed at the top of the straight pipe, a filter assembly for filtering impurities is provided inside the exhaust pipe, and a sliding groove is provided on the inner wall of the exhaust pipe.

[0006] The filter assembly includes a cone-shaped filter cylinder that is narrower at the top and wider at the bottom, an annular mounting plate fixedly connected to the bottom of the filter cylinder, a slider fixedly connected to the outer surface of the annular mounting plate, a locking bolt threaded between the slider and the exhaust pipe, and a cover plate fixedly connected to the top of the filter cylinder. The outer surface of the filter cylinder has filter holes. The outer diameter of the annular mounting plate is the same as the inner diameter of the exhaust pipe. The slider is slidably connected to the slide groove.

[0007] Furthermore, the outer surface of the exhaust pipe is provided with a first forward thread, and the inner surface of the bottom end of the straight pipe is provided with a first reverse thread, with the first forward thread and the first reverse thread corresponding to each other.

[0008] Furthermore, a second forward thread is provided on the inner surface of the top end of the straight pipe, and a second reverse thread is provided on the outer surface of the bent pipe, with the second forward thread and the second reverse thread being provided correspondingly.

[0009] Furthermore, the outer surface of the straight pipe is provided with a dust-blocking assembly for covering the opening of the bent pipe. The dust-blocking assembly includes a sliding sleeve slidably connected to the outer surface of the straight pipe, a connecting rod fixedly connected to the outer surface of the sliding sleeve, a mounting base fixedly connected to the top of the connecting rod, and a sleeve fixedly connected to the outer surface of the mounting base. The upper surface of the sleeve has a sleeve opening with a diameter equal to the outer diameter of the bent pipe.

[0010] Furthermore, the sleeve is positioned directly below the bend, and the sleeve is a component made of rubber.

[0011] Furthermore, the exhaust pipe, straight pipe, and bend are all components made of copper.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0022] Combination Figure 1 and Figure 4 A cooling tower reducer exhaust device includes an exhaust pipe 1 fixedly connected to the top of the reducer exhaust port, a straight pipe 2 movably disposed at the top of the exhaust pipe 1, and a bent pipe 3 movably disposed at the top of the straight pipe 2. The exhaust pipe 1 is provided with a filter assembly 5 for filtering impurities, and a groove 11 is provided on the inner wall of the exhaust pipe 1.

[0023] The present invention will be further described below with reference to the embodiments. Example

[0024] Please see Figure 1-Figure 5 The filter assembly 5 includes a cone-shaped filter cylinder 51 that is narrower at the top and wider at the bottom, an annular mounting plate 52 fixedly connected to the bottom of the filter cylinder 51, a slider 53 fixedly connected to the outer surface of the annular mounting plate 52, a locking bolt 54 threaded between the slider 53 and the exhaust pipe 1, and a cover plate 55 fixedly connected to the top of the filter cylinder 51. The outer surface of the filter cylinder 51 has filter holes 511. The outer diameter of the annular mounting plate 52 is the same as the inner diameter of the exhaust pipe 1. The slider 53 is slidably connected to the slide groove 11. The filter holes 511 on the outer surface of the filter cylinder 51 can effectively block impurities in the gas discharged from the reducer, so that the impurities adhere to the inner surface of the filter cylinder 51, protecting the exhaust pipe 1 from contamination. The filter cylinder 51 is fixed inside the exhaust pipe 1 by the locking bolt 54. By removing the locking bolt 54 and using the slider 53 and slide groove 11 in a sliding connection manner, the filter cylinder 51 can be easily pulled out of the exhaust pipe 1 for cleaning or replacement, preventing impurities from clogging the filter holes 511 and greatly simplifying the maintenance process.

[0025] The outer surface of the exhaust pipe 1 is provided with a first forward thread 12, and the inner surface of the bottom end of the straight pipe 2 is provided with a first reverse thread 22. The first forward thread 12 and the first reverse thread 22 are correspondingly arranged. The design of the first forward thread 12 and the first reverse thread 22 makes it easy to quickly connect or disconnect the straight pipe 2 from the exhaust pipe 1 by rotating it, which is convenient for cleaning or replacing the straight pipe 2. At the same time, when the first forward thread 12 and the first reverse thread 22 are tightly engaged, they can form a good sealing interface, reducing the risk of gas leakage.

[0026] The inner surface of the top end of the straight pipe 2 is provided with a second forward thread 21, and the outer surface of the bent pipe 3 is provided with a second reverse thread 31. The second forward thread 21 and the second reverse thread 31 are set in correspondence. The bent pipe 3 can be installed or disassembled by simply rotating the bent pipe 3, which facilitates cleaning or replacement of the bent pipe 3 and realizes rapid assembly and maintenance on site.

[0027] A dust-blocking assembly 4 for covering the opening of the bend 3 is provided on the outer surface of the straight pipe 2. The dust-blocking assembly 4 includes a sliding sleeve 41 slidably connected to the outer surface of the straight pipe 2, a connecting rod 42 fixedly connected to the outer surface of the sliding sleeve 41, a mounting base 43 fixedly connected to the top of the connecting rod 42, and a sleeve 44 fixedly connected to the outer surface of the mounting base 43. The upper surface of the sleeve 44 has a sleeve opening 441 with a diameter equal to the outer diameter of the bend 3. The diameter of the sleeve opening 441 on the sleeve 44 is precisely matched with the outer diameter of the bend 3, which makes it easy to completely cover the opening of the bend 3 when no exhaust is being discharged, effectively preventing dust or other foreign objects from entering the bend 3 and keeping the inside of the bend 3 clean. The sliding connection between the sliding sleeve 41 and the outer surface of the straight pipe 2 allows the dust-blocking assembly 4 to slide up and down along the straight pipe 2, making it easy to quickly open or close the opening of the bend 3 as needed.

[0028] The sleeve 44 is positioned directly below the bend 3 and is made of rubber. Rubber has natural elasticity. When the sleeve 44 covers the outer surface of the bend 3, its soft edges can fit tightly against the outer wall of the bend 3 to form an effective sealing layer and prevent external dust, moisture and other contaminants from entering.

[0029] Exhaust pipe 1, straight pipe 2, and bend pipe 3 are all made of copper. Copper is a metal with extremely high thermal conductivity, which facilitates efficient heat conduction from the exhaust gas of the reducer and accelerates the cooling process of the hot gas. At the same time, copper has natural corrosion resistance, which helps to maintain the stability and durability of the structure.

[0030] In use, the filter cartridge 51 is fixed inside the exhaust pipe 1 by locking bolt 54. The straight pipe 2 is quickly connected to the exhaust pipe 1 by rotating the straight pipe 2. At this time, the first forward thread 12 and the first reverse thread 22 are tightly engaged. The bent pipe 3 is quickly connected to the straight pipe 2 by rotating the bent pipe 3. At this time, the second forward thread 21 and the second reverse thread 31 are tightly engaged. The filter holes 511 on the outer surface of the filter cartridge 51 can effectively block impurities in the gas discharged from the reducer, so that the impurities adhere to the inner surface of the filter cartridge 51, protecting the exhaust pipe 1 from contamination. When not in use, the dust blocking component 4 can slide up and down along the straight pipe 2 by sliding sleeve 41 and the outer surface of straight pipe 2, which can quickly close the opening of bent pipe 3. When cleaning is required, the bent pipe 3 and straight pipe 2 are removed, the locking bolt 54 is removed, and the filter cartridge 51 is easily pulled out from the exhaust pipe 1 for cleaning or replacement by using slider 53 and sliding groove 11 to prevent impurities from clogging the filter holes 511.
