Description

A high-efficiency heat exchanger cleaning brush mechanism Technical Field

[0001] This utility model belongs to the technical field of heat exchanger cleaning brushes, and in particular relates to a high-efficiency heat exchanger cleaning brush mechanism. Background Technology

[0002] High-efficiency heat exchangers significantly improve heat exchange efficiency by optimizing fluid flow, increasing heat transfer area, or enhancing turbulence effects. A typical structure, such as the wound-tube heat exchanger, utilizes the reverse winding of adjacent spiral tubes to create strong turbulence, increasing the heat transfer coefficient by more than 30% compared to traditional equipment. High-flux tubes accelerate bubble nucleation through a porous surface coating, and combined with a connecting tunnel design to agitate the fluid, achieving twice the heat transfer density of bare tubes with the same energy consumption. Internally corrugated externally threaded tubes employ a combination of internal spiral corrugations and external threads, disrupting the boundary layer and accelerating condensate discharge. Effectively reduces thermal resistance; the corrugated tube, through its inner and outer raised corrugations, ensures continuous mixing of the fluid, simultaneously increasing the heat transfer coefficient inside and outside the tube by 40% to 60%; the T-groove tube and the inner groove tube provide vaporization nuclei through their surface concave cavity structure, enabling the boiling heat transfer coefficient to exceed 10,000 W / (m²·K), making them particularly suitable for low temperature difference conditions; the low-finned tube and the high-finned tube achieve efficient heat exchange in compact spaces and high-pressure environments respectively by cutting the boundary layer with fins and enhancing disturbance. Among them, the bimetallic high-finned tube combines the advantages of two metals, further extending the service life of the equipment.

[0003] For example, Chinese patent CN207741632U discloses a cleaning device for heat exchangers, including a device body. Support rods are provided on both sides of the device body, and drive motors are mounted on the support rods. The output end of the drive motor is connected to a drive shaft, and a conveyor belt is sleeved on the outside of the drive shaft. A mounting frame is welded to the device body, and a rotating motor is mounted on the mounting frame. The output end of the rotating motor is connected to a sleeve rod, and a telescopic rod is provided at the output end of the sleeve rod. Installing the rotating motor on the outside of the device body facilitates its protection and maintenance. During use, the working length of the telescopic rod can be adjusted by adjusting the locking device, improving the adaptability of the equipment. A T-shaped groove is provided on the mounting plate, allowing different numbers of mounting rods and brushes to be installed in the groove as needed, and fixed using blocks, facilitating overall use and improving efficiency.

[0004] The above-mentioned patent has the following problems: In actual use, it can only clean heat exchangers of a single model and size, and cannot be adapted to heat exchangers with different inner diameters. Its adaptability is poor, which increases the workload of staff and is not conducive to staff use. In view of this, we propose a high-efficiency heat exchanger cleaning brush mechanism. Summary of the Invention

[0005] The purpose of this invention is to provide a high-efficiency heat exchanger cleaning brush mechanism to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a high-efficiency heat exchanger cleaning brush mechanism, comprising:

[0007] A collection box is provided with a heat exchanger shell on the top of the collection box. Fixed plates are fixedly connected to both sides of the collection box. A hydraulic lifting rod is fixedly installed on the top of one of the fixed plates. A lifting plate is fixedly connected to the output end of the hydraulic lifting rod. A rotating tube is rotatably installed on the top of the lifting plate and extends to the bottom of the lifting plate.

[0008] A flow divider block is connected to the bottom of the rotating tube, and the output end of the flow divider block is connected to a telescopic tube, one end of which is connected to a nozzle.

[0009] A rotating assembly is disposed on the top of the lifting plate and is used to drive the rotating tube to rotate;

[0010] A movable scrubbing assembly is disposed at the bottom of the diversion block and is used to scrub the heat exchanger housing.

[0011] In this technical solution, by activating the hydraulic lifting rod, the lifting plate, nozzle, and brush are moved to the inside of the heat exchanger shell. By activating the electric push rod, the connecting plate, the second motor, and the brush are moved, and the telescopic tube is extended, moving the brush to the inner wall of the heat exchanger shell. By activating the second motor, the second rotating shaft and the brush rotate, and the brush cleans the inner wall of the heat exchanger shell. By activating the water pump, water from the water tank is drawn into the connecting tube, rotating tube, diverter block, and telescopic tube, and sprayed out from the nozzle, thus rinsing the heat exchanger shell. Through the above structure, the inner wall of the heat exchanger shell can be cleaned and scrubbed. This device is adaptable to heat exchanger shells of different inner diameters, has strong adaptability, and is convenient for operators to use.

[0012] By starting the first motor, the output end of the first motor drives the first rotating shaft and the driving gear to rotate. Since the driving gear and the driven gear are meshed, the rotation of the driving gear drives the driven gear and the rotating tube to rotate. Subsequently, the flow divider, nozzle and brush plate move around the inner wall of the heat exchanger shell in a circular motion. At this time, the inner wall of the heat exchanger shell can be thoroughly cleaned. With the above structure, the inner wall of the heat exchanger shell can be thoroughly cleaned.

[0013] In the above technical solution, further, a telescopic sleeve is fixedly connected to the top of one of the fixed plates, and a telescopic rod is slidably installed inside the telescopic sleeve, with the top of the telescopic rod fixedly connected to the bottom of the lifting plate.

[0014] In this technical solution, the telescopic rod is slidably installed inside the telescopic sleeve, which makes the lifting plate more stable when moving.

[0015] In the above technical solution, the rotating component further includes a first motor, which is disposed on the top of the lifting plate. The output end of the first motor is fixedly connected to a first rotating shaft. The bottom of the first rotating shaft is rotatably mounted on the top of the lifting plate. A driving gear is fixedly connected to the outside of the first rotating shaft, and a driven gear is fixedly connected to the outside of the rotating tube. The driving gear and the driven gear are meshed together.

[0016] In this technical solution, by starting the first motor, the output end of the first motor drives the first rotating shaft and the driving gear to rotate. Since the driving gear and the driven gear are meshed, the rotation of the driving gear can drive the driven gear and the rotating tube to rotate, and then drive the flow divider block, nozzle and brush plate to move circumferentially around the inner wall of the heat exchanger shell.

[0017] In the above technical solution, a fixed frame is fixedly connected to the top of the lifting plate, and the first motor is fixedly installed on the fixed frame.

[0018] In this technical solution, the fixed frame makes the first motor more stable during operation.

[0019] In the above technical solution, a water tank is further fixedly installed on the top of the lifting plate, a connecting pipe is connected to one side of the water tank, a water pump is installed outside the connecting pipe, a bearing is installed inside the rotating pipe, and the connecting pipe is installed on the inner ring of the bearing.

[0020] In this technical solution, by using a bearing, the connecting pipe will not rotate when the rotating pipe rotates.

[0021] In the above technical solution, the mobile brushing assembly further includes an electric push rod, which is fixedly installed on the diverter block. The output end of the electric push rod is fixedly connected to a connecting plate, and the connecting plate is fixedly connected to a telescopic tube. A second motor is fixedly installed on one side of the connecting plate, and a second rotating shaft is fixedly connected to the output end of the second motor. A brush plate is fixedly connected to one end of the second rotating shaft.

[0022] In this technical solution, by starting the second motor, the output end of the second motor drives the second rotating shaft and the brush plate to rotate, at which time the brush plate can clean the inner wall of the heat exchanger shell.

[0023] In the above technical solution, the top of the collection box is provided with multiple through holes that are evenly distributed.

[0024] In this technical solution, multiple equally spaced through holes allow cleaning water to enter the interior of the collection tank.

[0025] The beneficial effects of this utility model are:

[0026] 1. By activating the hydraulic lifting rod, the lifting plate, nozzle, and brush plate are moved to the inside of the heat exchanger shell. By activating the electric push rod, the connecting plate, second motor, and brush plate are moved, and the telescopic tube is extended, moving the brush plate to the inner wall of the heat exchanger shell. By activating the second motor, the second rotating shaft and brush plate rotate, and the brush plate cleans the inner wall of the heat exchanger shell. By activating the water pump, water from the water tank is drawn into the connecting tube, rotating tube, diverter block, and telescopic tube, and sprayed out from the nozzle, thus rinsing the heat exchanger shell. Through the above structure, the inner wall of the heat exchanger shell can be cleaned and scrubbed. This device is adaptable to heat exchanger shells of different inner diameters, has strong adaptability, and is convenient for operators to use.

[0027] 2. By starting the first motor, the output end of the first motor drives the first rotating shaft and the driving gear to rotate. Since the driving gear and the driven gear are meshed, the rotation of the driving gear drives the driven gear and the rotating tube to rotate. Subsequently, the flow divider, nozzle and brush plate move around the inner wall of the heat exchanger shell in a circular motion. At this time, the inner wall of the heat exchanger shell can be thoroughly cleaned. With the above structure, the inner wall of the heat exchanger shell can be thoroughly cleaned.
