Description

Technical Field

[0001] This utility model relates to the field of air cooler technology, and in particular to an air cooler tube bundle with a detachable protective sleeve. Background Technology

[0002] Air coolers, as important heat exchange equipment, are widely used in industries such as petroleum, chemical, and power. Their core component is the tube bundle, which is usually composed of a large number of finned tubes. These fins have a precise structure and are relatively fragile. During transportation, installation, and operation, they are easily deformed or damaged by external impacts, scratches, or debris, which seriously affects the heat exchange efficiency and service life of the air cooler.

[0003] To effectively protect the tube bundle, a physical protective sleeve or cover is usually installed on the outside of the tube bundle. In existing technical solutions, these protective sleeves are mostly fixed to the air cooler's casing or frame using fasteners such as bolts and clips. Although this connection method is structurally robust, its drawbacks become apparent when the internal tube bundle needs to be cleaned, inspected, or maintained regularly.

[0004] Maintenance personnel must use specialized tools such as wrenches to loosen and remove numerous bolts one by one before they can remove the protective sleeve. After completing the maintenance work, the tedious steps of aligning holes and tightening bolts must be repeated. The entire disassembly and assembly process is not only time-consuming and labor-intensive, reducing the efficiency of maintenance work, but it is also particularly inconvenient to operate in environments with limited space or at heights. Small parts such as disassembled bolts are also easily lost, bringing additional difficulties to on-site management.

[0005] Therefore, this utility model proposes a detachable protective sleeve to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an air cooler tube bundle with a detachable protective sleeve, aiming to improve and solve the problems of cumbersome and time-consuming disassembly and assembly of protective devices and poor versatility in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an air cooler tube bundle with a detachable protective sleeve, comprising: a housing, an installation mesh fixedly connected to the outer wall of the housing, and a main sleeve; and a quick-release assembly for detachably installing the main sleeve onto the installation mesh.

[0008] The quick-release assembly includes a fixing plate fixedly connected to the outer wall of the mounting mesh, and a mounting square plate fixedly connected to the outer wall of the main sleeve. The fixing plate has a circular hole and a magnetic locking block. A locking block is rotatably connected to the mounting square plate via a pivot, and a spring is connected between the locking block and a resilient pin that moves within the locking block.

[0009] The locking block is provided with a slot for magnetic adsorption and engagement with the magnetic card block. During assembly, the locking block is initially positioned with the fixing plate by magnetic adsorption. Then, the locking block rotates relative to the fixing plate, so that the elastic pin is inserted into or disengaged from the round hole under the elastic force of the spring, thereby realizing the rapid mechanical locking or unlocking between the main sleeve and the installation net.

[0010] Preferably, the air cooler tube bundle with detachable protective sleeve further includes a modular splicing assembly, which includes a secondary sleeve detachably connected to the end of the main sleeve, and a connecting ring for locking the connection between the main sleeve and the secondary sleeve.

[0011] Preferably, an extension plate is fixedly connected to the outer wall of the connecting ring; a pin is fixedly connected to the outer wall at the connection between the main sleeve and the auxiliary sleeve; a handle is rotatably connected to the extension plate, and the handle is used to lock the extension plate onto the pin.

[0012] Preferably, the end of the pin passes through the handle, and the end of the pin is locked by a nut.

[0013] Preferably, the connection between the end of the main sleeve and the end of the auxiliary sleeve is a threaded connection.

[0014] Preferably, the air cooler tube bundle with a detachable protective sleeve further includes an installation assembly, wherein the housing and the installation mesh are both components of the installation assembly; the installation assembly also includes a filter plate covering the housing.

[0015] Preferably, the air cooler tube bundle with a detachable protective sleeve further includes a heat dissipation assembly, which includes a mounting shell disposed inside the housing and a ventilation plate fixedly connected to the top of the mounting shell.

[0016] Preferably, the connection between the mounting plate and the main sleeve is welding.

[0017] This utility model has the following beneficial effects: In this invention, a quick-release component is set up, and the magnetic attraction between the magnetic card block and the locking block is used to achieve initial positioning. Then, by rotating the locking block, the elastic pin is inserted into the round hole of the fixing plate under the action of the spring to achieve mechanical locking. This solves the problem that the existing protective devices mostly use bolt fixing, and the disassembly and assembly process is cumbersome, time-consuming and requires special tools. It achieves the technical effect of quick and tool-free disassembly and assembly of the protective sleeve, which greatly improves the efficiency of installation and maintenance.

[0018] 2. In this utility model, by setting up a modular splicing assembly consisting of a main sleeve, a secondary sleeve, and a connecting ring, sleeves of different lengths are combined by means of threaded connection and locking with connecting ring. This solves the problem in the prior art that the protective device has a fixed size, cannot be adapted to air cooler housings of different specifications, and has poor versatility. It achieves the technical effect that the total length of the protective sleeve can be flexibly adjusted, making it applicable to a variety of equipment models and enhancing the versatility and adaptability of the product.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 5 This utility model provides an air cooler tube bundle with a detachable protective sleeve, which aims to solve the problems of cumbersome and time-consuming disassembly and assembly of protective devices and poor versatility of fixed dimensions in the prior art.

[0023] The air cooler tube bundle with a detachable protective sleeve includes a mounting assembly 1, a heat dissipation assembly 2, a quick-release assembly 3, and a modular splicing assembly 4. The mounting assembly 1 includes a housing 103 and a mounting mesh 102. The mounting mesh 102 is fixedly connected to the outer wall of the housing 103. The housing 103 provides a mounting carrier for the entire device. The main sleeve 401 is used to protect the tube bundle inside the air cooler. The main sleeve 401 is detachably mounted on the mounting mesh 102 via the quick-release assembly 3.

[0024] Specifically, the quick-release assembly 3 is used to achieve quick connection and separation between the main sleeve 401 and the mounting mesh 102. The quick-release assembly 3 includes a fixing plate 301 and a mounting square plate 305. The fixing plate 301 is fixedly connected to the outer wall of the mounting mesh 102, and the mounting square plate 305 is fixedly connected to the outer wall of the main sleeve 401. The fixing plate 301 has a circular hole 303 and a magnetic suction block 302. A locking block 304 is rotatably connected to the mounting square plate 305 via a rotating shaft 306. The locking block 304 can rotate around the axis of the rotating shaft 306, and the locking block 304 is movable inside the locking block 304. A resilient pin 308 is provided, and a spring 307 is connected between the resilient pin 308 and the locking block 304. The spring 307 surrounds the outer periphery of the resilient pin 308 and provides an elastic thrust to the resilient pin 308. The locking block 304 is provided with a slot for magnetic adsorption and engagement with the magnetic card block 302. During installation, the slot of the locking block 304 is brought close to the magnetic card block 302 to achieve magnetic adsorption and positioning. Then, the locking block 304 is rotated. When the resilient pin 308 is aligned with the round hole 303, the resilient pin 308 is inserted into the round hole 303 under the elastic force of the spring 307 to achieve mechanical locking.

[0025] The modular splicing component 4 includes a secondary sleeve 402 and a connecting ring 403. The ends of the main sleeve 401 and the secondary sleeve 402 are detachably connected. In this embodiment, the end of the main sleeve 401 is provided with an external thread, and the end of the secondary sleeve 402 is correspondingly provided with an internal thread that mates with the external thread. The main sleeve 401 and the secondary sleeve 402 are initially fixed by the threaded connection. The connecting ring 403 is used to reinforce and lock the connected parts. The connecting ring 403 is sleeved at the connection between the main sleeve 401 and the secondary sleeve 402. An extension plate 405 is fixedly connected to the outer wall of the connecting ring 403 and is fixed on the outer wall of the connection between the main sleeve 401 and the secondary sleeve 402. A pin 407 is connected to an extension plate 405, and a handle 404 is rotatably connected to it. The handle 404 is used to lock the extension plate 405 onto the pin 407. The handle 404 has a through hole for the pin 407 to pass through. The end of the pin 407 passes through the through holes of the extension plate 405 and the handle 404 in sequence. The end of the pin 407 is also locked by a nut 406. The threaded engagement between the nut 406 and the pin 407 further tightens the handle 404 and prevents loosening. This structure, in which the main and auxiliary sleeves 402 are threadedly connected and then tightened from the outside by the connecting ring 403, ensures that the assembled sleeve has sufficient connection strength and structural stability.

[0026] In a preferred embodiment, the air cooler tube bundle mounting assembly 1 also includes a filter plate 101, which is installed on the housing 103. The filter plate 101 can perform preliminary filtration of the air entering the housing 103 to prevent external debris such as leaves and fluff from entering the air cooler and causing blockage or damage to the tube bundle.

[0027] As another preferred embodiment, the air cooler tube bundle is also provided with a heat dissipation component 2, which includes a mounting shell 202 and a ventilation plate 201. The mounting shell 202 is disposed inside the housing 103, and the ventilation plate 201 is fixedly connected to the top of the mounting shell 202. The structure of the ventilation plate 201 is conducive to air circulation, which can assist the air cooler tube bundle in heat dissipation and ensure the stability of the entire device under long-term operation.

[0028] As another preferred embodiment, in order to ensure a more stable connection of the quick-release assembly 3, the mounting square plate 305 and the main sleeve 401 are fixedly connected by welding. This fixing method has high structural strength and can withstand the vibration generated during equipment operation.

[0029] Working principle: When it is necessary to install protective sleeves on air cooler housings 103 of different sizes, firstly, according to the actual required length, the modular splicing component 4 is adjusted to rotate and tighten the internal thread end of the auxiliary sleeve 402 and the external thread end of the main sleeve 401 to achieve a preliminary connection. Then, the connecting ring 403 is placed on the connection between the main sleeve 401 and the auxiliary sleeve 402. The handle 404 is turned so that the extension plate 405 is pressed onto the pin post 407. Finally, the nut 406 is locked to the end of the pin post 407 to complete the firm fixation of the entire spliced ​​sleeve and form an integral protective sleeve. When the assembled protective sleeve needs to be installed onto the housing 103, hold the protective sleeve and align the mounting plate 305 on it with the fixing plate 301 on the mounting mesh 102. Due to the magnetic force of the magnetic card block 302, the locking block 304 will be automatically attracted and positioned onto the fixing plate 301, completing the initial positioning of the installation. After that, the operator can rotate the entire protective sleeve or rotate the locking block 304 separately. The locking block 304 will rotate around the rotating shaft 306. When it rotates to the predetermined position, the elastic pin 308 inside the locking block 304 will align with the round hole 303 on the fixing plate 301. Under the push of the spring 307, the elastic pin 308 will automatically insert into the round hole 303, completing the mechanical locking. The entire installation process does not require tools and is quick and convenient to operate. When the protective sleeve needs to be disassembled for inspection or maintenance of the internal tube bundle, the process is reversed. First, manually pull the elastic pin 308 out of the round hole 303 to overcome the elastic force of the spring 307. Then, rotate the protective sleeve in the opposite direction to release the mechanical locking state between the locking block 304 and the fixing plate 301. At this time, the entire protective sleeve can be removed from the installation net 102 by relying solely on the magnetic force connection of the magnetic card block 302 and applying slight force.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
