In petrochemical, building materials, metallurgy and other industries, a large amount of waste heat is generated. According to the characteristics of different industries, our company has developed a mechanically efficient elastic vibration machine with independent intellectual property rights. The waste heat boiler dust and dust is strong at 60 degrees Celsius, and it is easy to ash. It is not easy to clean up. “The ash accumulation of the waste heat boiler will seriously affect the heat transfer effect. Therefore, effectively solving the ash accumulation problem is the key to the success of the waste heat boiler capacity optimization. The mechanical and efficient elastic vibration machine developed by our company based on the characteristics of the above-mentioned boiler smoke and dust is suitable for waste heat boilers with strong viscosity of smoke and dust. The principle of this equipment is to generate a series of suitable vibration frequencies for the boiler as a whole, and not cause damage to the boiler. Under the circumstances, the multi-mode vibration mode inherent in the boiler is fully excited. The maximum effective vibration is achieved. The best boiler dust removal effect is achieved. The power source of this equipment is a 0.55KW motor. Drive the driving sprocket, and then drive the driven sprocket through the chain. The driven sprocket drives the hammer lifting device to raise the hammer head to the set height. Under the action of the falling hammer device. The hammer head drops the striking spring vibration rod, A set of butterfly springs on the spring vibration rod converts the instantaneous impact force of the key head to intermediate frequency vibration and releases it. That is to ensure the impact force from the impact point Passed through the cleaned surface without damaging the boiler equipment. At present, our company develops and produces elastic mechanical vibration machines, which are at the top level in China, comparable to foreign technology. The equipment is more advanced in design, reasonable in structure, convenient in maintenance, economical and durable, and quality Reliable, good ash cleaning effect, and effectively solve the problem of boiler ash accumulation. It is well received by users.
Manual for rapping machine
Structure and use
The mechanically efficient elastic rapping machine is composed of a box body, a pendulum, a transmission component, and a guide shaft. Function: It is mainly used for regular dust cleaning inside the waste heat boiler, so that the dust in the furnace can be cleaned in time.
The working principle of the rapping machine can be known from the schematic structure, which is composed of a transmission device, a swing device and a spring anvil assembly device. The falling weight is rotated by the transmission device. When it is turned to a certain position, the fork device is used to drive the swing device to a certain height. Then, the pendulum is allowed to fall freely and hit the guide shaft of the anvil, and at the same time, a suitable vibration frequency is generated, so that the vibration mode of the natural frequency of the water-cooled wall is fully excited. The maximum effective vibration is obtained for the boiler Accumulated ash for best removal.
The main technical parameters
|Rapping frequency||3 times min|
|Rapping strength||30 ~ 100KN|
Adjustment of rapping parameters
Rapping parameters can be fine-tuned based on dust content, dust cohesion, and boiler operation.
Rapping frequency: designed to be three times per minute. In special cases, the number of rapping times can be redesigned according to user requirements.
Vibration strength: The vibratory strength is determined by the height of the pendulum. The pendulum has been raised to a certain height during assembly. Generally, no adjustment is required. The user can also adjust to the second gear according to the use situation, so that the vibratory strength is reduced.
Rapping time: The rapping time usually needs to be adjusted when the factory is operating. Generally, a single rapping time is designed to be 5 ~ 8 minutes at a time. When the ash accumulation is serious, the rapping time can be appropriately extended. Depending on the boiler conditions.
The body of the rapping machine is shipped from the whole machine. Each product is strictly adjusted and the test run is generally not adjusted. At the same time, a set of guide shaft components is also boxed. The installation of the rapping machine shall be carried out according to the design drawings. The guide shaft is welded to the corresponding position on the boiler beam.
Operation and maintenance
After the equipment is installed, check the whole machine. The reducer should be filled with oil, and the running parts should be well lubricated. The pendulum device should be manually operated first. The machine will run smoothly after a few times of manual vibration. Then start the motor and test the vibration several times. It can be put into operation. The motor cannot be reversed during operation. The oil of the reducer needs to be changed once after one to three months of operation. When put into normal operation, it is necessary to lubricate the lubricating parts, fill the main shaft with butter, lubricate the oil cup oil cup, and lubricate the copper sleeve chain. Regularly fill with oil afterwards.
The rapping process should be single-machine rapping. After one rapping machine finishes working and stops, then start the second rapping machine. According to the design, all the rapping machines will be rotated one cycle at a time. The rapping program. Rapping time. The rapping period can be controlled manually or automatically. The automatic control system can be designed and debugged according to customer requirements.
1. When wiring the motor of the rapping machine, you must open the back cover of the casing and observe the movement direction of the pendulum to slowly lift it. If the wiring error is corrected immediately, otherwise the equipment will be damaged.
2 Always pay attention to the tightening of the fasteners to prevent loosening and falling off caused by vibration.
