Description

Technical Field

[0001] This utility model relates to the field of water pipe cleaning technology, and in particular to a cleaning device for circulating cooling water pipes in waste incineration plants. Background Technology

[0002] The circulating cooling water pipeline cleaning device in a waste incineration plant is a key piece of equipment to ensure the stable operation of the waste incineration power generation system. During the waste incineration process, the circulating cooling water system undertakes the important task of cooling the equipment and maintaining the stability of the process temperature. However, after long-term operation, scale, silt, microbial slime and other impurities are easily deposited in the pipeline, which leads to poor water flow, reduced heat exchange efficiency, and even pipeline blockage and equipment failure. Therefore, a pipeline cleaning device is needed to remove scale.

[0003] Existing waste incineration plant circulating cooling water pipeline cleaning devices can use pipeline cleaning robots for cleaning. The cleaning robot drives a rotating disc to break up scale. During the cleaning process, some debris particles can easily splash and adhere to the inside of the pipeline, thus affecting the quality of pipeline cleaning. Utility Model Content

[0004] To overcome the problem of existing waste incineration plant circulating cooling water pipeline cleaning devices, pipeline cleaning robots can be used for cleaning. The cleaning robot drives a rotating disc to break up scale. During the cleaning process, some debris particles are easily splashed and adhered to the inside of the pipeline, thus affecting the quality of pipeline cleaning.

[0005] The technical solution of this utility model is as follows: a cleaning device for circulating cooling water pipelines in a waste incineration plant, comprising a mounting base, track wheels, and a crushing wheel. The track wheels are rotatably connected to the bottom end of the mounting base, and the crushing wheel is rotatably connected to the end of the mounting base. Several crushing teeth are fixed on the side wall of the crushing teeth, and several clamps are rotatably connected to the side wall of the crushing wheel near the nozzle. The outer surface of each clamp is fitted with a mounting sleeve, and the side wall of each mounting sleeve is woven with a brush.

[0006] Furthermore, the crushing wheel and crushing teeth are fixedly connected to form an integrated structure, and a servo motor is fixedly installed in the middle of the mounting base. The crushing wheel is fixedly installed at the output end of the servo motor through a coupling.

[0007] Furthermore, several slots are symmetrically distributed on the side of the crushing wheel for clamp insertion, and the external dimensions of the clamp are adapted to the internal dimensions of the slots, thus improving the stability of the clamp rotation.

[0008] Furthermore, a groove is provided on the side wall of the clamp away from the mounting sleeve. The internal dimensions of the groove are adapted to the thickness of the crushing wheel, which improves the convenience of clamp installation.

[0009] Furthermore, a limit sleeve is threadedly connected to the outer surface of the clamp near the groove, and a locking block is fitted on the outer surface of the clamp away from the limit sleeve, which improves the stability of the clamp rotation.

[0010] Furthermore, a nozzle is fixedly installed on the top of the mounting base near the crushing wheel, and a water pump is fixedly installed on the top of the mounting base. A second connecting pipe is inserted into the input end of the water pump, and a first connecting pipe is inserted into the other end of the water pump.

[0011] Furthermore, two sets of electric actuators are symmetrically fixed on the side wall of the mounting base. Each electric actuator has a retainer fixed at its output end, and a roller is rotatably connected to the middle of each retainer, which improves the stability of the mounting base.

[0012] Furthermore, a sleeve is inserted at the end of the mounting base away from the crushing wheel. The sleeve is connected to the mounting base, and a power cord and a data cord are inserted in the middle of the sleeve, which improves the safety of the cleaning process.

[0013] The beneficial effects of this utility model are:

[0014] Compared to traditional waste incineration plant circulating cooling water pipeline cleaning devices, this device uses a mounting base, tracked wheels, crushing wheels, and crushing teeth in combination to move and crush the inner wall of the cooling water circulating pipeline. The crushing teeth and clamps work together to drive the mounting sleeve and brush to rotate synchronously, making it easy to adjust the brush cleaning angle. The brush further washes the inner wall of the pipeline to reduce debris residue, thus improving the quality of pipeline cleaning. Secondly, by setting a limit sleeve, a groove, and a locking block, rotating the limit sleeve can expose the groove, making it easy to remove the clamp from the groove, thus improving the convenience of replacing the mounting sleeve and brush.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Among the currently discovered feasible technologies, the following are described:

[0023] During the operation of a waste incineration plant, the circulating cooling water system plays a crucial role. It effectively removes the large amount of heat generated by the incineration equipment, ensuring that the equipment operates stably within a safe temperature range. However, over time, various types of dirt inevitably accumulate inside the circulating cooling water pipes, such as scale, microbial sludge, and corrosion products. This dirt not only reduces the heat transfer efficiency of the pipes and increases energy consumption, but may also lead to pipe blockage and accelerated corrosion, seriously affecting the normal operation of the circulating cooling water system and even threatening the safe production of the waste incineration plant.

[0024] The design of the circulating cooling water pipeline cleaning device for waste incineration plants is centered on meeting the pipeline cleaning needs under the complex operating conditions of waste incineration plants. Following the design principles of high efficiency, safety, environmental protection, and intelligence, its main objectives are to quickly and thoroughly remove various types of dirt and grime from the pipelines while minimizing damage; the operation process should be simple and safe, reducing the labor intensity of operators; the waste generated during the cleaning process should be easy to collect and dispose of, avoiding secondary pollution; and the device should possess a certain level of automation and intelligence, capable of real-time monitoring of the cleaning status and automatically adjusting cleaning parameters according to pipeline conditions to improve cleaning efficiency and quality.

[0025] The cleaning device for circulating cooling water pipelines in waste incineration plants mainly consists of a power system, a cleaning actuator, a control system, a waste collection and treatment system, and an auxiliary support system.

[0026] The power system is the energy source of the entire cleaning device, providing the necessary power to the cleaning actuator. It is usually driven by electricity or hydraulics. Electric drive has the advantages of simple structure, convenient control, and low operating cost, and is suitable for some pipes with small diameter and easy cleaning. Hydraulic drive has the characteristics of high output power, high torque, and smooth operation, and can meet the cleaning needs of large-diameter pipes with stubborn dirt. The power system is equipped with a high-performance motor or hydraulic pump, which transmits power to the cleaning actuator through a transmission device to ensure that the cleaning tool can clean the pipe at the appropriate speed and torque.

[0027] The cleaning actuator is the core part of the device, directly responsible for removing dirt from the pipeline. It mainly includes different types of cleaning tools and transmission components. The cleaning tools are designed and selected according to the material of the pipeline, the pipe diameter, and the type and characteristics of the dirt.

[0028] The control system is the "brain" of the cleaning device. It is responsible for monitoring and regulating the entire cleaning process. The control system uses an advanced programmable logic controller (PLC) or industrial computer as the core control unit. It collects the operating parameters of the cleaning actuator in real time through sensors, such as speed, torque, pressure, and position.

[0029] The auxiliary support system provides necessary support and protection for the cleaning device, ensuring its stability and safety during operation. It includes a support frame, a traveling mechanism, and protective devices.

[0030] Before using the cleaning device, a comprehensive inspection and evaluation of the circulating cooling water pipeline is required to understand the pipeline's material, diameter, length, and the distribution and type of internal dirt. Based on the inspection results, appropriate cleaning tools and parameters should be selected, and the cleaning device should be installed and debugged in place. At the same time, ensure that the waste collection and treatment system is operating normally and connect the sewage discharge pipeline to the designated sewage treatment facility.

[0031] Please refer to Figures 1-5 A waste incineration plant circulating cooling water pipeline cleaning device includes a mounting base 1, tracked wheels 2, and a crushing wheel 3. The tracked wheels 2 are rotatably connected to the bottom end of the mounting base 1, and the crushing wheel 3 is rotatably connected to the end of the mounting base 1. Several crushing teeth 4 are fixedly mounted on the side wall of the crushing wheel 3. The crushing wheel 3 and the crushing teeth 4 are fixedly connected to form an integrated structure. A servo motor is fixedly mounted in the middle of the mounting base 1. The crushing wheel 3 is fixed to the output end of the servo motor via a coupling. Starting the servo motor drives the crushing wheel 3 and the crushing teeth 4 to rotate. The crushing teeth 4 contact the scale on the inner side wall of the pipeline to achieve crushing and cleaning. As this is existing technology, it will not be described in detail here. Several clamps 5 are rotatably connected to the side wall of the crushing wheel 3 near the nozzle 8. The outer surface of each clamp 5 is fitted with an installation sleeve 6. The side wall of each installation sleeve 6 is woven with a brush 7. The brush 7 is made of nylon. Several slots 16 are opened on the side of the crushing wheel 3. The slots 16 are symmetrically distributed for the clamps 5 to be inserted. The external dimensions of the clamps 5 are adapted to the internal dimensions of the slots 16, which improves the stability of the clamps 5 rotation. When the crushing wheel 3 rotates, the clamps 5, after crushing, drive the brush 7 to further scrub the inner wall of the pipe, thereby improving the quality of pipe cleaning.

[0032] A groove 18 is provided on the side wall of the clamp 5 away from the mounting sleeve 6. The internal dimensions of the groove 18 are adapted to the thickness of the crushing wheel 3, which improves the ease of installation of the clamp 5. A limit sleeve 17 is threadedly connected to the outer surface of the clamp 5 near the groove 18. A locking block 19 is fitted on the outer surface of the clamp 5 away from the limit sleeve 17, which improves the stability of the clamp 5 rotation.

[0033] A nozzle 8 is fixedly mounted on the top of the mounting base 1 near the crushing wheel 3. A water pump 10 is fixedly mounted on the top of the mounting base 1 by bolts. A second connecting pipe 11 is inserted into the input end of the water pump 10. The other end of the second connecting pipe 11 is connected to a water source. A first connecting pipe 9 is inserted into the other end of the water pump 10. The other end of the first connecting pipe 9 is inserted into the side wall of the nozzle 8. Starting the water pump 10 can pump water into the nozzle 8 for atomized spraying and rinsing. Two sets of electric push rods 13 are symmetrically fixed on the side wall of the mounting base 1. Each output end of the electric push rod 13 is fixed with a retainer 14. A roller 15 is rotatably connected in the middle of each retainer 14. Starting the electric push rod 13 can push the two rollers 15 to move horizontally and support them on the inner side wall of the pipe, which improves the stability of the mounting base 1. A sleeve 12 is inserted into the end of the mounting base 1 away from the crushing wheel 3. The sleeve 12 is connected to a servo motor. A power line and a data line are inserted in the middle of the sleeve 12. The sleeve 12 is used to protect the circuit and improve the safety of cleaning.

[0034] When using the waste incineration plant circulating cooling water pipeline cleaning device, first place the device inside the pipeline to be cleaned, then connect the external power supply, and rotate the track wheel 2 to drive the device. Start the servo motor to drive the crushing wheel 3 and crushing teeth 4 to rotate. The crushing teeth 4 contact the scale on the inner wall of the pipeline to achieve crushing and cleaning. Start the water pump 10 to draw clean water and spray it out through the nozzle 8 to rinse the inner wall of the pipeline. The clamp 5 rotates synchronously with the crushing wheel 3. The clamp 5 is rotatably connected inside the slot 16 to facilitate the adjustment of the angle of the brush 7 during rotation, so that the brush 7 can further scrub the inner wall of the pipeline, thereby avoiding debris residue and improving the quality of pipeline cleaning.

[0035] Considering that the brush 7 needs to be replaced after wear and tear, a limiting sleeve 17, a slot 18, and a locking block 19 are provided. The slot 18 passes through the clamp 5 for the crushing wheel 3 to engage. Rotating the limiting sleeve 17 can close the slot 18, thereby supporting and limiting the locking block 19 and the limiting sleeve 17, so that the clamp 5 can be stably rotated and connected to the outer surface of the crushing wheel 3, thus improving the convenience of replacing and disassembling the mounting sleeve 6 and the brush 7.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
