Description

Technical Field

[0001] The invention belongs to the technical field of boiler room, in particular to a cooling mechanism for boiler installation. Background Art

[0002] As an important energy conversion equipment, the boiler plays a vital role in various industrial production and energy supply systems. It converts chemical energy into thermal energy by burning fuel, and then generates steam or hot water to provide power for various process or heating systems. However, during operation, a large amount of heat will be generated inside the boiler. If this heat cannot be dissipated in a timely and effective manner, the boiler temperature will rise sharply, which may cause a series of problems.

[0003] Existing devices generally rely on fans for blowing air to cool down the boiler. However, during the actual operation of the boiler, its temperature continues to rise, which poses a higher challenge to the cooling device. Unfortunately, the cooling devices currently widely used have certain limitations in design. They can often only provide a fixed blowing intensity and cannot be flexibly adjusted according to the actual temperature of the boiler. Specifically, traditional cooling devices usually set a fixed fan speed. Regardless of how the temperature of the boiler changes, the fan runs at a constant speed. This design may still have a certain cooling effect when the boiler temperature first rises, but as the boiler temperature continues to rise, the fixed fan speed becomes inadequate and cannot effectively control the boiler temperature within a safe range.

[0004] In addition, since it cannot be adjusted according to the temperature, traditional cooling devices also have a certain waste in energy consumption. When the boiler temperature is low, excessive blowing will not only fail to further improve the cooling effect, but will increase energy consumption and reduce the efficiency of the entire system. Therefore, it needs to be improved and optimized. Summary of the invention

[0005] In order to solve the problem raised in the above background technology that the existing device can only provide a fixed blowing intensity and cannot be flexibly adjusted according to the actual temperature of the boiler, resulting in poor cooling effect when the boiler temperature continues to rise, energy waste at low temperatures, and low overall system efficiency, the present invention provides a cooling and cooling mechanism for boiler installation.

[0012] Preferably, a motor protection shell is fixedly mounted on the outer wall of the protection box away from the air outlet, and two motors are fixedly mounted on the inner wall of the motor protection shell. The output shafts of the two motors extend into the protection box and are rotatably connected to the protection box.

[0013] Preferably, a plurality of fan blades are fixedly mounted on the output shafts of the two motor protection shells, respectively, and the plurality of fan blades are designed to be equidistantly distributed in a circle.

[0014] Preferably, a limit plate is provided on the top of the T-shaped telescopic rod, and the limit plate is fixedly connected to the protection box and the partition.

Conversely, when the boiler temperature drops, the baffle moves downward to reduce the ventilation volume to avoid overcooling, so that the cooling device can be flexibly adjusted according to the actual temperature of the boiler, ensuring the cooling effect while also improving energy utilization efficiency.

[0020] The present invention effectively blocks dust and impurities in the air and protects the cleanliness of the inside of the boiler through the arrangement of the filter, while the rotating rod and the two cross brushes fixedly mounted on the outer wall thereof constitute an efficient cleaning system. When the baffle moves, the cylinder thereon is movably connected with the groove rail, driving the rotating rod and the cross brush to rotate, ensuring that both sides of the filter can be evenly cleaned and avoiding the reduction in cooling effect due to clogging of the filter. At the same time, the cleaning process does not require manual intervention, greatly reducing the maintenance burden. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 11 As shown, the present invention provides a cooling mechanism for boiler installation, comprising a protection box 1, a partition 101 is fixedly installed inside the protection box 1, two ventilation pipes 2 are fixedly installed on the bottom outer wall of the partition 101, a Y-shaped pipe 201 is fixedly installed on one side of the two ventilation pipes 2, an air outlet 103 is opened on one side of the protection box 1, the air outlet 103 is connected with the Y-shaped pipe 201 and the two ventilation pipes 2, and two horizontal plates 5 are fixedly installed on the side where the partition 101 and the protection box 1 are close to each other;

[0035] The tops of the two horizontal plates 5 are respectively provided with driving mechanisms, and the insides of the two ventilation pipes 2 are provided with regulating and cleaning mechanisms;

[0036] The driving mechanism includes an airbag 6 arranged on the top of one of the horizontal plates 5, and a contact piece 1 601 is fixedly installed on the top of the airbag 6. A plurality of limit strips 11 are respectively fixedly installed on the tops of the two horizontal plates 5, and a cross 7 is slidably installed on the inner walls of the plurality of limit strips 11. A contact piece 2 701 is fixedly installed on the outer wall of the cross 7 at the top of the airbag 6, and a T-shaped telescopic rod 702 is fixedly installed on the top of the cross 7 at the top of the airbag 6. A connecting rod 8 is slidably sleeved on the outer wall of the T-shaped telescopic rod 702, and the connecting rod 8 and the contact piece 2 701 are elastically connected by a spring 703. A round rod 9 is fixedly installed on the top of the other cross 7, and the connecting rod 8 is slidably connected to the round rod 9.

[0037] Through the heat expansion principle of the airbag 6, intelligent sensing of the boiler temperature is realized. When the boiler temperature rises, the airbag 6 expands accordingly, triggering the drive mechanism to work. The cooling intensity can be automatically adjusted without human intervention. Through the design of the adjustable cleaning mechanism, the dual functions of cooling and cleaning are realized. When the airbag 6 expands, it not only promotes the movement of the cross 7 and the T-shaped telescopic rod 702, but also drives the linkage of the connecting rod 8 and the round rod 9, thereby realizing the cleaning of the filter 4. There is a difference in size between the two groups of adjusting and cleaning mechanisms, which is specifically manifested in that one group of mechanisms is a proportionally reduced version of the other group of mechanisms.

[0038] like Figures 9 to 11 As shown, the regulating and cleaning mechanism includes a baffle 3 slidably installed inside the ventilation duct 2, the top of the baffle 3 extends out of the ventilation duct 2, a cylinder 301 is fixedly installed on the outer wall of the baffle 3 close to the Y-tube 201, a connecting cross bar 302 is fixedly installed on the baffle 3, a filter screen 4 is rotatably installed inside the ventilation duct 2, a rotating rod 401 is rotatably installed through the center of the filter screen 4, two cross brushes 402 are fixedly provided on the outer wall of the rotating rod 401, and the two cross brushes 402 are respectively located on both sides of the filter screen 4, a groove rail 403 is fixedly provided on the outer wall of the rotating rod 401 close to the baffle 3, and the cylinder 301 is movably connected to the groove rail 403.

[0039] By sliding the baffle 3 installed inside the ventilation pipe 2, intelligent adjustment of the ventilation volume is achieved. When the boiler temperature rises, the driving mechanism pushes the baffle 3 to move upward, thereby opening the channel of the ventilation pipe 2 and allowing more cooling airflow to pass through. Conversely, when the boiler temperature drops, the baffle 3 moves downward to reduce the ventilation volume to avoid overcooling, so that the cooling device can be flexibly adjusted according to the actual temperature of the boiler, ensuring the cooling effect while also improving the energy utilization efficiency. The setting of the filter 4 effectively blocks dust and impurities in the air and protects the cleanliness of the inside of the boiler, while the rotating rod 401 and the two cross brushes 402 fixedly mounted on its outer wall constitute an efficient cleaning system. When the baffle 3 moves, the cylinder 301 thereon is movably connected with the groove rail 403, driving the rotating rod 401 and the cross brush 402 to rotate, ensuring that both sides of the filter 4 can be evenly cleaned, and avoiding the reduction of the cooling effect due to the blockage of the filter 4. At the same time, the cleaning process does not require manual intervention, which greatly reduces the maintenance burden.

[0040] like Figures 7 and 8 As shown, a rectangular rod 704 is fixedly installed on the top of the cross 7, and an L-shaped connecting rod 901 is fixedly installed on the top of the round rod 9. The rectangular rod 704 and the L-shaped connecting rod 901 are fixedly connected to the corresponding connecting cross rod 302; a contact ring 1 801 is fixedly installed on the top of the connecting rod 8, and a contact ring 2 902 is fixedly installed on the bottom of the L-shaped connecting rod 901. The vertical positions of the contact ring 1 801 and the contact ring 2 902 coincide with each other. A motor protection shell 10 is fixedly installed on the outer wall of the protection box 1 away from the air outlet 103, and two motors 1001 are fixedly installed on the inner wall of the motor protection shell 10. The output shafts of the two motors 1001 extend into the protection box 1 and are rotatably connected to the protection box 1. A plurality of fan blades 1002 are respectively fixedly installed on the output shafts of the two motor protection shells 10, and the plurality of fan blades 1002 are designed to be distributed in a circle with equal distances.

[0041] By starting the motor 1001, the fan blades 1002 will rotate rapidly, generating a strong wind flow, which will be blown toward the boiler through the ventilation pipe 2 and the Y-shaped pipe 201 to achieve rapid cooling.

[0042] like Figures 2 to 5 As shown, a limit plate 1011 is provided on the top of the T-shaped telescopic rod 702, and the limit plate 1011 is fixedly connected to the protection box 1 and the partition 101. A rectangular groove 12 is provided on the inner wall of the protection box 1, and the connecting rod 8 passes through the rectangular groove 12 and is slidably connected to the rectangular groove 12. Two vertical grooves 1021 are provided on the side of the partition 101 close to the air outlet 103, and the two vertical grooves 1021 are slidably connected to the corresponding connecting cross bar 302 and the L-shaped connecting rod 901 respectively. The two vertical grooves 1021 are designed to be staggered, and the top of the vertical groove 1021 close to the airbag 6 side is located in the middle of the other vertical groove 1021.

[0043] By using the rectangular groove 12 as a movable channel for the connecting rod 8, a precise sliding connection with the connecting rod 8 is achieved. When the connecting rod 8 moves with the action of the driving mechanism, it will slide smoothly along the rectangular groove 12, ensuring the accurate movement trajectory of the connecting rod 8. Through the sliding connection design of the two staggered vertical grooves 1021 on the partition 101 and the connecting cross bar 302 and the L-shaped connecting rod 901, the device can achieve flexible adjustment of the ventilation volume and ensure the stable operation and high efficiency of the entire adjustment mechanism.

[0044] The working principle and use process of the present invention:

[0045] The airbag 6 in the protection box 1 is in a state of not expanding due to heat, the contact piece 1 601 is not in contact with the contact piece 2 701, the motor 1001 is not started, the baffle 3 closes the ventilation pipe 2, the air flow cannot pass through, and the cross brush 402 on the filter 4 is in a stationary state.

[0046] When the outside temperature rises, the airbag 6 in the protection box 1 begins to expand due to the heat, and the contact piece 1 601 on the top of the airbag 6 contacts the contact piece 2 701, triggering the electric fusion connection, and the corresponding motor 1001 is started, and its output shaft drives the fan blades 1002 to start rotating, generating initial wind flow, and under the continuous expansion of the airbag 6, the cross 7 on its top is pushed to move upward, and the cross 7 drives the rectangular rod 704, the T-shaped telescopic rod 702 and the connecting rod 8 to move upward together, and the rectangular rod 704 drives the baffle 3 to move upward by connecting the cross bar 302. After the baffle 3 moves, a gap is generated in the originally closed ventilation pipe 2, and the wind begins to blow out through the ventilation pipe 2, the Y-shaped pipe 201 and the air outlet 103, so as to initially cool down the boiler.

[0047] When the baffle 3 drives the cylinder 301 on its outer wall to move, the cylinder 301 converts the vertical movement into the rotational movement of the groove rail 403 and the rotating rod 401 through the movable connection of the groove rail 403. The rotating rod 401 drives the cross brushes 402 on both sides to rotate, cleans both sides of the filter 4, and ensures smooth ventilation.

[0048] When the temperature continues to rise, the airbag 6 continues to expand, driving the T-shaped telescopic rod 702 and the connecting rod 8 to continue to move upward. When the T-shaped telescopic rod 702 contacts the limit plate 1011, the connecting rod 8 squeezes the spring 703 to continue to move upward, and the contact ring 1 801 at the top of the connecting rod 8 contacts the contact ring 2 902 at the bottom of the L-shaped connecting rod 901, triggering the start of another motor 1001, and the other fan blade 1002 starts to rotate, generating more wind flow. The rise of the connecting rod 8 also drives the L-shaped connecting rod 901 and the connecting cross bar 302 and the baffle 3 connected to the L-shaped connecting rod 901 to move together, and the channel in the other ventilation pipe 2 is also opened. The wind flow in the two ventilation pipes 2 is blown out through the Y-shaped tube 201 and the air outlet 103 together, so as to cool the boiler with high intensity.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
