Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to industrial boiler equipment, in particular to a boiler ash lowering pipe device for preventing ash blocking. Background Art
[0002] With the development of industry, our demand for energy continues to increase, and the use of industrial boilers such as thermal power plants is becoming more and more common. However, the treatment of ash generated during boiler combustion has become a thorny issue. These ashes will not only affect the thermal efficiency of the boiler, but also pollute the environment. In order to solve this problem, an anti-ash blocking boiler ash pipe device came into being. This device is of great significance for achieving clean and efficient operation of the boiler and protecting the environment.
[0003] According to the search of China Utility Model Publication No.: CN209740214U, a device for preventing the ash conveying pipeline of a boiler is disclosed. A cyclone valve is arranged on the ash conveying pipeline. When the discharge valve of the silo pump is opened, the control solenoid valve of the cyclone valve is opened. After the cyclone valve is opened, negative pressure is formed in the whole pipeline, and compressed air enters the valve body and enters the valve pipe from the inclined hole on the valve pipe, so that the ash that loses power along the way is re-spun. After the air and ash come into contact, the fluidity of the ash is increased and the friction and density between the ash and the pipe wall are reduced, so that it is not easy to be blocked; the punching port is connected to the valve body. It is connected to the stamping pipe, which can be connected to the stamping equipment to meet the stamping needs of different pressures. A solenoid valve is set on the stamping pipe, which is flexible to adjust, easy to control and safe to use. A vibrator is set on the ash conveying pipeline. The vibration of the vibrator will drive the ash conveying pipeline to jump, so that the ash is suspended in the ash conveying pipeline, reducing the ash conveying resistance and reducing the ash deposition on the ash conveying pipeline during ash conveying. A blower is set on the ash conveying pipeline to further improve the blockage phenomenon of the ash conveying pipeline. Starting the blower to blow the ash along the ash conveying line can improve the ash conveying efficiency.
[0004] However, when implementing the above technical solution, the following problems exist: the device uses compressed air to blow the dust on the inner wall to reduce friction, which is suitable for situations where there is less dust adhesion. When the boiler is used for a long time, stubborn combustion materials and dust attached to the inner wall may not be blown away. The device uses vibration and a blower to shake out the dust and transport it. Excessive vibration will cause the internal structure of the pipe to loosen, and the wind force of the blower cannot complete the transportation when encountering a curved pipe. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] This product is equipped with an inner wall cleaning device for the ash inlet.

This design has a simple structure and is easy to maintain. It can work under extreme temperature and pressure conditions, has no mechanical wear, and has a long service life.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-4 The utility model provides an embodiment: a boiler ash lowering pipe device for preventing ash blocking, comprising an ash inlet 1 and an anti-blocking mechanism 3, an ash lowering pipe 2 is arranged at the bottom end of the ash inlet 1, the anti-blocking mechanism 3 is arranged on the outside and inside of the ash inlet 1, a motor 301 is arranged on the left side of the ash inlet 1, and the right end of the motor 301 is connected to a first turntable 302.
[0026] Specifically, the motor 301 and the first turntable 302 are threadedly connected, one end of the belt 303 is sleeved on the outer side of the first turntable 302, and the other end of the belt 303 is sleeved on the second turntable 304. The second turntable 304 is larger than the first turntable 302. When the motor 301 rotates, it drives the first turntable 302 to rotate, and then drives the belt 303 and the second turntable 304 to rotate. The larger second turntable 304 can reduce the waste of kinetic energy and reduce the burden on the motor 301. This transmission method has a simple structure and low noise.
[0027] Specifically, the right end of the second turntable 304 is threadedly connected to the rotating shaft 305, and the rotating shaft 305 passes through the ash inlet 1. The right end of the rotating shaft 305 is connected to the ash sweeper 306. The ash sweeper 306 is made of fluororubber. There are multiple groups of ash sweepers 306. The rotation of the second turntable 304 drives the rotation of the rotating shaft 305 and the ash sweeper 306, which can sweep away the dust and combustion products attached to the inner wall of the ash inlet 1, reduce wall hanging and keep the inner wall smooth. The fluororubber material is soft and has strong high temperature resistance. It will not damage the internal structure of the device during the cleaning process. It is suitable for cleaning the inner wall of the boiler and the device has a long service life.
[0028] Specifically, a water inlet pipe 307 is arranged in front of the ash discharge pipe 2, and the rear end flange of the water inlet pipe 307 is connected to an electromagnetic pump 308.

[0029] Specifically, a magnetic tube 309 is provided inside the electromagnetic pump 308, and a coil 310 is sleeved on the outside of the magnetic tube 309. The material of the coil 310 is copper. When current passes through the coil 310 wound on the electrode, an alternating magnetic field will be generated around the coil 310 and the magnetic tube 309. This alternating magnetic field will induce an electromagnetic force in the magnetic circuit of the pump. This force will act on the free charges in the water. When the fluid moves, it will be affected by the electromagnetic force. This force will push the fluid medium to move along the direction of the magnetic field, thereby forming water pumping.

[0032] Working principle: When it is found that dust accumulation affects the use of the device, the ash inlet 1 is closed to stop the ash feeding work, and the motor 301 is turned on. The motor 301 rotates to drive the first turntable 302 to rotate, and then drives the belt 303 and the second turntable 304 to rotate. The second turntable 304 drives the rotation of the shaft 305 and the ash sweeper 306 to sweep the dust attached to the inner wall of the ash inlet 1 and drop it into the ash discharge pipe 2. Then, the electromagnetic switch 311 is pressed, and the power supply 312 is connected to the coil 310 to form a closed magnetic circuit, and the water in the water inlet pipe 307 is pumped to the valve switch 313. The valve switch 313 is opened to flow to the nozzle 314 for spraying.
