Description

Technical Field

[0001] The invention relates to the technical field of industrial cooling tower structures, in particular to a small cooling tower with a flexible position-changing tower body structure. Background Art

[0002] Industrial cooling towers are the core heat dissipation equipment in industrial circulating water systems and are primarily used in scenarios where continuous waste heat removal is required. For example, they are used to condense high-temperature steam discharged from steam turbines in thermal power plants and nuclear power plants; to control the temperature of equipment such as reactors and distillation towers in the chemical and petrochemical industries; to provide circulating cooling water for high-temperature equipment such as blast furnaces and rolling mills in the metallurgical industry; to dissipate heat from central air conditioners and refrigeration units in refrigeration systems; and to dissipate heat and cool server cabinets in data centers.

[0003] Existing industrial cooling tower structures use natural ventilation structures or mechanical ventilation structures. For example, large cooling towers used in large power plants, due to their large tower height, can drive the airflow through natural convection generated by the tower height and air temperature difference, and usually do not have a mechanical ventilation structure. However, small cooling towers used in some other fields do not have sufficient tower height, so when necessary during use, they require an external mechanical ventilation structure to promote air flow.

[0004] However, there are many installation restrictions for small cooling towers: 1. Generally, an external bottom fan (blast type) is connected to the ground to push the air upward, but when the ground installation space is insufficient, this structure is difficult to implement, and the bottom fixing and connection structure must also be dealt with; 2. If an external top fan (induced draft type) is used to extract the hot air, it will be difficult to build the top external fan, and there will be safety hazards due to factors such as poor wind resistance after high-position installation. 3. In addition, users need to purchase multiple cooling towers that are compatible with the above two external mechanical ventilation installation structures as backup; 4. It cannot be flexibly adjusted according to its own use environment. For example, it is difficult to remove a cooling tower from an installation system that uses a top induced draft structure and install it in an installation system that uses a bottom blast structure. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: in order to overcome the deficiencies in the prior art, a small cooling tower with a flexible position-changing tower body structure is provided.

[0006] The technical solution adopted by the present invention is: a small cooling tower with a flexible tower body structure, comprising a cooling tower body, a sub-cabinet frame movably connected to one side of the body, a first guide rail group installed on the top and side surfaces of the body, a second guide rail group arranged in the sub-cabinet frame, and an integrated mechanical ventilation assembly slidably connected to the first and second guide rail groups; The integrated mechanical ventilation assembly includes a base, a mounting base is rotatably connected to the base via a rotating shaft, an induced draft fan and a blower are respectively mounted on the left and right sides of the upper end surface of the mounting base, and a built-in channel connected to the air outlet at the lower end of the induced draft fan is provided in the mounting base and the base on one side of the induced draft fan; The top of the body is provided with an air guide locking mechanism, including an air guide seat installed in the body, the center of the air guide seat is slidably connected to an elastic locking component through a spring guide column, trapezoidal blocks are provided on the left and right sides of the air guide seat, the elastic locking component includes a central slider slidably set on the spring guide column, the left and right sides of the central slider are connected to locking plates through transverse spring members, and the lower end of the locking plate is provided with a movable block that is close to the inclined surface of the trapezoidal block; When the integrated mechanical ventilation assembly is installed on the tower top, the induced draft fan rotates to the left, the elastic locking assembly moves upward, and the locking plates on the left and right sides are inserted into the built-in channel and pushed from the inside to lock the base under the action of the transverse spring member; when the elastic locking assembly moves downward, as the left and right movable blocks move obliquely downward on the corresponding trapezoidal blocks, the left and right transverse spring members are compressed inward, and the locking plates are gradually withdrawn from the base and the lock on the base is released; By adopting the above technical solution, through the tightening of the elastic locking component and the connection between the base and the first guide rail group, the integrated mechanical ventilation component is more stable when installed on the tower top and has stronger wind resistance.

[0007] The bottom of the body is provided with a bottom cavity and a side door for placing an integrated mechanical ventilation component. When the integrated mechanical ventilation component is installed at the bottom of the tower, the blower rotates to the left, and the air outlet of the blower is connected to the bottom blowing diffuser inside the bottom of the tower through a docking pipe.

[0008] Furthermore, the air guide seat of the present invention is provided with an air guide channel; By adopting the above technical solution, the air guide channel matches the air duct inside the tower, so that the upper and lower air ducts can flow smoothly.

[0009] Furthermore, the central slider of the present invention is provided with a rotating pull ring, and the air guide seat is provided with a fixing hook that cooperates with the rotating pull ring; By adopting the above technical solution, manual locking and unlocking operations are facilitated when disassembling and assembling the ventilation components.

[0010] Furthermore, the first guide rail group and the second guide rail group described in the present invention are guide rods, and the connection structure between the base and the first guide rail group and the second guide rail group adopts a guide slip ring that is slidably sleeved on the guide rod.

[0011] Furthermore, the guide slip rings of the present invention are respectively installed at the four feet of the base, and the guide slip rings are provided with a one-way elastic movable door; By adopting the above technical solution, the operation of mounting and derailing the base is made more convenient and quicker.

[0012] Furthermore, the main body and the auxiliary cabinet frame of the present invention are connected by a quick-release lock; By adopting the above technical solution, the auxiliary cabinet frames can be installed in a combined manner as needed or separated for separate storage and transportation.

[0013] Furthermore, the top of the auxiliary cabinet frame of the present invention is also provided with an electric hoist for hoisting the integrated mechanical ventilation assembly; By adopting the above technical solution, when the integrated mechanical ventilation assembly is transferred within the sub-cabinet frame, it can be hoisted and controlled with the help of an electric hoist, which is more labor-saving.

[0014] Compared with the prior art, the present invention has the following advantages: 1. Aiming at the actual installation environment and usage scenarios of small industrial cooling towers, the mechanical ventilation structure of the present invention cooperates with the installation structure of the cooling tower body to achieve flexible adjustment and rapid installation; 2. Users do not need to equip multiple spare cooling towers of different specifications (top draft or bottom forced draft). No matter which system requires the above two types of cooling towers, they can be competent. The mechanical ventilation structure can be directly adjusted according to the needs, which reduces the economic pressure of having to purchase multiple specifications of spare units in the existing technology. 3. The cooling tower can be disassembled from a system with Class I specifications (such as top induced draft) and relocated to a Class II specification (such as bottom blast draft) system by changing the mechanical ventilation position as needed, further improving the utilization of existing equipment, embodying its flexibility and reducing production costs. 4. When the cooling tower is idle or does not require mechanical ventilation, the integrated mechanical ventilation assembly can be directly moved to the auxiliary cabinet frame. It can be separated from the auxiliary cabinet frame for separate storage, which can achieve functions such as classified storage, separate transportation, multi-purpose use of one machine, and reduction of total weight / total volume; 5. The integrated mechanical ventilation assembly not only integrates the induced draft fan and blower, and can be easily adjusted and installed with the rotating structure, but also can cooperate with the induced draft guide locking mechanism when installed on the top, making the top installation structure stable and highly wind-resistant.

An induced draft fan 8 and a blower 9 are respectively mounted on the left and right sides of the upper end surface of the mounting base 7. A built-in channel 10 communicating with the air outlet at the lower end of the induced draft fan is provided in the mounting base 7 and the base 5 on one side of the induced draft fan 8; The top of the body 1 is provided with an air guide locking mechanism, including an air guide seat 11 installed in the body 1, and an elastic locking assembly is slidably connected to the center of the air guide seat 11 through a spring guide column 12. Trapezoidal blocks 13 are provided on the left and right sides of the air guide seat 11. The elastic locking assembly includes a central slider 14 slidably set on the spring guide column 12, and the left and right sides of the central slider 14 are connected to locking plates 16 through transverse spring members 15. The lower end of the locking plate 16 is provided with a movable block 17 that is close to the inclined surface of the trapezoidal block 13; When the integrated mechanical ventilation assembly is installed on the top of the tower, the induced draft fan 8 rotates to the left, the elastic locking assembly moves upward, and the locking plates 16 on the left and right sides are inserted into the built-in channel 10 and are pushed from the inside to lock the base 5 under the action of the transverse spring member 15; when the elastic locking assembly moves downward, as the left and right movable blocks 17 move obliquely downward on the corresponding trapezoidal blocks 13, the left and right transverse spring members 15 are compressed inward, and the locking plates 16 are gradually withdrawn from the base 5 and the lock on the base 5 is released; The bottom of the main body 1 is provided with a bottom cavity and a side door for placing an integrated mechanical ventilation component. When the integrated mechanical ventilation component is installed at the bottom of the tower, the blower 9 rotates to the left, and the air outlet 18 of the blower 9 is connected to the bottom blowing diffuser 20 inside the bottom of the tower through the docking pipe 19.

[0019] An air guiding channel 21 is provided in the air guiding seat 11 .

[0020] A rotating pull ring 22 is provided on the central slider 14 , and a fixing hook 23 that cooperates with the rotating pull ring 22 is provided on the air guide seat 11 .

[0021] The first and second guide rail groups 3 and 4 serve as guide rods. The connection structure between the base 5 and the first and second guide rail groups 3 and 4 utilizes guide rings 24 that are slidably sleeved onto the guide rods. The guide rings 24 are mounted on the four base feet of the base 5 and are equipped with one-way elastic movable doors 25.

[0022] The main body 1 and the auxiliary cabinet frame 2 are connected by a quick-release lock 26. An electric hoist for hoisting the integrated mechanical ventilation assembly is also provided at the top of the auxiliary cabinet frame.

[0023] Working principle: Step 1. During conventional installation, ensure that the blower on the mounting base is on the left side. Install the integrated mechanical ventilation assembly directly on the bottom of the body and connect all pipes and lines. Step 2. If the bottom of the main unit needs to be converted to a top-induced draft structure due to site / environmental reasons or poor bottom-blowing performance, assemble the auxiliary cabinet frame with the main unit, move the integrated mechanical ventilation assembly to the bottom of the auxiliary cabinet frame, connect the guide rings on the base to the corresponding first and second guide rail groups, connect the hook of the electric hoist to the center of the mounting base, prepare for lifting and guiding, and simultaneously rotate the mounting base so that the induced draft fan is on the left. When the integrated mechanical ventilation assembly is moved to the top of the main body, the guide slip ring on one side of the second guide rail group is unlocked, and then the integrated mechanical ventilation assembly is pushed to the top installation position of the main body, and then the elastic locking assembly in the air induced guide locking mechanism is moved upward, so that the left and right locking plates are pushed from the inside to the locking base under the action of the transverse spring member. At this time, when the assembly is installed at the top high position, the internal locking and matching guide slip ring and the first guide rail group realize double limitation, which has better stability and strong wind resistance.

[0024] Step 3. When changing from a top induced draft structure to a bottom blower structure, just follow the steps in step 2 in reverse order.

[0025] Step 4. When the cooling tower is not in use, is idle, or needs to be packaged for storage / transportation, move the integrated mechanical ventilation assembly into the sub-cabinet and unlock the sub-cabinet from the main body. At this time, the sub-cabinet and the integrated mechanical ventilation assembly can be handled separately, which is more flexible.
