Description

Technical Field

[0001] This utility model relates to the field of cleaning technology for air preheaters in power plant boilers, specifically to a vibration descaling device for heat storage components. Background Technology

[0002] The heat storage components of the air preheater in a power plant boiler are made of thin iron plates with stamped stripes and diagonal lines, reinforced on all sides to form a single unit. As a heat storage component, each boiler air preheater consists of thousands of components. After long-term use, under the combined action of ammonia nitrogen and coal ash, scale and caking form inside the components and in the interlayer, clogging the pores, increasing the load, and affecting normal power generation. In the past, the thin iron plates were cut off from the sides and manually hammered one piece at a time to remove the scale and caking. This was not only inefficient and labor-intensive, but the components deformed after manual hammering, expanded too much when stacked, and were difficult to close. Moreover, the cleaning was not thorough and did not meet the requirements.

[0003] Utility model patent number 209006355U discloses a descaling device for air cooler tube bundles, including tracks and a moving mechanism. Two tracks are arranged between the tops of the tube boxes at both ends of the air cooler, along the length of the tube bundle. A moving mechanism reciprocates along the two tracks, and a vibration mechanism is mounted on the moving mechanism. The vibration mechanism includes a vibration motor, a flexible drive shaft, and vibration rods. The vibration motor is fixedly mounted on the frame of the moving mechanism, and the vibration rods hang down between the tube bundles of the air cooler, with one vibration rod between every two sets of tube bundles. However, this patent is not entirely in the same field and does not fully achieve automation. Utility Model Content

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] First embodiment:

[0025] refer to Figure 1 , Figure 2 A transmission-type integrated vibration platform includes a bed 1, which is made of a robust metal cuboid frame structure, providing a stable foundation support for the entire device. Multiple support legs 102 are installed at the bottom of the bed 1 to stably place it on the ground. Adjustable feet 103 are installed at the lower ends of the support legs 102, and each adjustable foot 103 consists of a screw, a nut, and a load-bearing plate. One end of the screw is connected to the support leg 102, and the other end passes through the load-bearing plate. The nut is located on the screw below the load-bearing plate. The adjustable feet 103 are placed on the ground, so that the load-bearing plate is in contact with the ground. When the ground is uneven and the bed 1 needs to be leveled, the nut is rotated, causing the nut to move up and down on the screw. If the nut rotates upward, it pushes the load-bearing plate upward, raising the bed 1 to the corresponding position; if the nut rotates downward, the load-bearing plate descends, lowering the bed 1 to that position. By adjusting the nuts of the adjustable feet 103 at different positions, the bed 1 can be leveled.

[0026] Multiple cylindrical rollers 4 are installed in parallel on the bed 1 via bearing seats 104, with a uniform spacing between each roller 4. The rollers 4 are made of high-strength and wear-resistant steel and are connected to the motor and reducer 6 via chains 501 and sprockets 502. They rotate at a uniform speed under the drive of the motor to realize the material conveying.

[0027] There is a support frame 7 on each side of the bed 1. The support frame 7 has an inverted "U" shape, and its two sides are fixed to the bed 1 by welding. The bottom edge of the "U" faces upward, and each bottom edge has two round holes. There are a total of 4 cylinders 8. The cylinder body passes through the round holes on the bottom edge of the support frame 7 and is fixed to the support frame 7 by bolts. The piston rod of the cylinder 8 passes through the round hole and faces downward. The cylinder 8 is equipped with an air inlet and an air outlet. The air compressor is connected to the air inlet and air outlet of the cylinder 8 through the air inlet pipe and the air outlet pipe to provide power to the cylinder 8.

[0028] An adjusting bolt is located at a specific position on the cylinder body of cylinder 8. This adjusting bolt is installed by engaging with a corresponding threaded hole on the cylinder body. Its design is intended to achieve precise control of the piston rod extension stroke, and it is a key component that replaces the traditional limit switch to realize the stroke control function.

[0029] On the inner side of each support frame 7, near the four corners of the vibration platform 11, there are four vertically installed columnar guide rods 9. One end of each guide rod 9 is welded to the support frame 7, and the other end is welded to the bed 1. A hollow cylindrical bushing 10 is slidably fitted onto the outer surface of each guide rod 9. This bushing is fixedly connected to the vibration platform 11 below the bed 1 by welding. The guide rods 9 and bushings 10 ensure the stability and guidance of the vibration platform 11 during lifting and lowering. The vibration platform 11 includes a rectangular baffle 1101, a base plate 1102, and a raised plate 1103. The raised plate 1103 is connected to the base plate 1102 by welding, and its position and size are adapted to the gap between the rollers 4. A vibrator is installed below the raised plate 1103. The baffle 1101 is vertically welded to both sides of the base plate 1102, and its position and width are adapted to the gap between the rollers 4.

[0030] refer to Figure 3 The position sensor 12 is a light sensor, mounted on the bed 1, near the end of the vibration platform 11, and positioned corresponding to a hole in the bottom plate of the vibration platform 11. In the non-working state, the position sensor 12 extends out of the bottom plate 1102 of the vibration platform 11.

[0031] The position sensor 12 is a light sensor, mounted on the bed 1, near the end of the vibration platform 11, and positioned corresponding to a hole in the bottom plate of the vibration platform 11. In the non-working state, the position sensor 12 extends out of the bottom plate 1102 of the vibration platform 11.

[0032] A light sensor is connected to a relay, which in turn is connected to a solenoid valve. Cylinder 8 is connected to an air compressor via an air pipe. Simultaneously, the circuit controlling the start of cylinder 8 and the circuit controlling the conveyor belt motor are connected in series with an interlocking mechanism. This series interlocking ensures that when the cylinder starts, the conveyor belt motor reliably stops, and the conveyor belt stops running, and vice versa, achieving automated control. The vibrator is located below the vibration platform, and its control circuit is connected in parallel with the cylinder's control circuit, both controlled by a time-delay relay.

[0033] Working principle:

[0034] In the non-operating state, the vibration platform 11 is located below the roller 4. When the heat storage element is conveyed to the position sensor 12 along with the roller 4, the photosensitive sensor detects the heat storage element and feeds back the detection signal to the air compressor relay. The relay closes, energizing the solenoid valve connected to it. After the solenoid valve is energized, the air compressor provides an air source, which is transmitted to the cylinder 8 through the air pipe, thereby driving the cylinder 8 to work; when the cylinder starting circuit is connected, the power supply circuit of the conveyor belt motor is automatically disconnected due to the action of the series interlock device, causing the motor to stop running.

[0035] Cylinder 8 first performs a lifting action. The piston rod of cylinder 8 retracts, driving the vibration platform 11 upward along the guide rod 9 and through the bushing 10. The protruding plate 1103 and the baffle 1101 first rise from the gap between the rollers 4 until their tops exceed the height of the upper edge of the rollers 4. At this time, the position sensor 12 is located below the base plate of the vibration platform 11. The entire system is equipped with a time delay relay with a preset working time. During the preset working time, the cylinder remains in working state, and the air source is continuously and stably supplied to the cylinder, so that the extension rod of the cylinder can remain in the retracted and lifted state for the preset time. At the same time, the vibrator located below the vibration platform also works, generating appropriate vibration to vibrate and remove scale from the workpiece. Due to the blocking effect of the baffle 1101, the heat storage element is always on the vibration platform 11.

[0036] After the preset working time ends, the time delay relay activates, controlling the air source to stop supplying air to the cylinder. The cylinder's extension rod reverses its movement, the vibrator stops vibrating, and the cylinder 8 descends. The top of the protruding plate 1103 returns to a height below the lower edge of the roller 4. The position sensor 12 extends out of the base plate 1102 of the vibration platform 11 again. At this time, the circuit control reconnects the power to the motor, the motor starts, and drives the conveyor belt to continue conveying the heat storage element. The heat storage element is conveyed backward from the roller 4. The next heat storage element repeats the previous process, and so on in a continuous flow operation.

[0037] Second embodiment:

[0038] refer to Figure 4 Based on the first embodiment, the force-applying rods in this embodiment are electric push rods, and the power device is an electric motor. The motor is selected as a servo motor or a stepper motor to achieve precise control of the rotation speed and precise control of the closing and pressing stroke. There are a total of 4 electric push rods, and the motor housings are fixed to the inverted "U"-shaped support frame 7 by screws and nuts.

[0039] There are four inwardly concave groove-shaped guide grooves 13, which are evenly distributed at the four corners of the vibration platform 11. One end of the guide groove 13 is welded to the support frame 7, and the other end is welded to the bed 1. A slider 14 slides in the guide groove 13, but other directions of movement are restricted. The slider 14 is connected to the vibration platform 11 by welding.

[0040] The motor 15 is connected to the reducer 16. The output shaft of the reducer 16 is connected to the driving synchronous pulley 17. The shaft seat 21 is fixed on the support frame 7. The driven synchronous pulley 19 is on the shaft seat 21. The driving synchronous pulley 17 and the driven synchronous pulley 19 are connected by a synchronous belt, which is a belt 18. The driven synchronous pulley 19 is connected to a lead screw 20. The support frame 7 has a through hole. The lead screw 20 passes through the through hole and a nut 22 that matches the thread is installed on the threaded surface of the lead screw 20. The outside of the nut 22 is fixedly connected to an electric push rod 23. The electric push rod 23 is connected to a slider 14. After the motor 15 is started, the mechanical force drives the driving synchronous pulley 17 to rotate through the reducer 16. The belt 18 drives the driven synchronous pulley 19 to rotate and drives the lead screw 20 to rotate, which drives the nut 22 to push the electric push rod 23 out. The slider 14 and the vibration platform 11 descend. When the vibration platform 11 needs to rise, the motor 15 reverses and drives the lead screw 20 to rotate in the opposite direction, thereby retracting the electric push rod 23.

[0041] Other features are the same as in the first embodiment.

[0042] The improvement in this embodiment lies in the fact that the electric actuator has precise control performance, enabling more accurate position control and meeting the requirements of working scenarios with higher requirements for the lifting height and speed of the vibration platform. The performance and reliability of the device are further improved by optimizing the transmission device and guide components.

[0043] It should be noted that the above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
