A CLEANING DEVICE FOR THE INNER WALL OF A BOILER USED IN THERMAL

POWER GENERATION

TECHNICAL FIELD

The present invention belongs to the field of boiler cleaning used in thermal power generation, specifically relating to a cleaning device for the inner wall of a boiler used in thermal power generation.

BACKGROUND

Boilers are important equipment in power plants. After prolonged operation, the inner walls of the boiler often accumulate a large amount of dirt. If this dirt is not removed in a timely manner, it not only increases energy consumption but also poses safety risks.

Chinese patent CN214813350U discloses a device for removing dirt from the inner wall of a thermal power plant boiler. This device includes a box body, a water pump, and a top cover. One side of the box body is sealed with an observation port, and a Venturi tube is welded to one side of the water pump. One end of the Venturi tube is welded to a discharge pipe, and a hopper is welded to the top of the Venturi tube. A connecting pipe is welded to the bottom of the hopper, and a return pipe is welded to one side of the box body. An electric motor is mounted at the bottom of the return pipe, and a discharge pipe is welded to the other side of the box body. This device can quickly separate the discharged dirt from the cleaning solution, preventing the discharged dirt from continuing to consume effective components in the cleaning solution, thereby reducing the consumption of the cleaning solution. It improves the flowability of dirt falling off the inner wall of the boiler, which not only reduces the consumption of the cleaning solution but also enhances the discharge efficiency of the dirt, increasing the cleaning rate of the boiler’s inner wall and making it suitable for dirt removal in thermal power plant boilers.

However, during the cleaning of the boiler’s inner wall, due to the influence of wateu508522 quality, a certain amount of dirt remains on the surface, and the dirt adheres to the inner wall surface and is relatively stubborn. Using only a water gun for cleaning cannot completely remove the dirt.

In light of this, the present invention is proposed.

SUMMARY

The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a cleaning device for the inner wall of a boiler used in thermal power generation. This device addresses the problem mentioned in the background technology, where, during the cleaning of the boiler’s inner wall, certain dirt remains on the surface due to the influence of water quality. The dirt adheres to the inner wall surface and is relatively stubborn, making it impossible to completely remove with the sole use of a water gun.

To solve the above technical problem, the basic idea of the technical solution adopted by the present invention is described as follows:

A cleaning device for the inner wall of a boiler used in thermal power generation includes: a fixed frame, where one side of the bottom surface of the fixed frame is fixedly connected to a positioning plate, and a grinding component for removing stubborn dirt from the boiler’s inner wall is arranged on one side of the bottom surface of the fixed frame, which is located adjacent to the positioning plate. The surface of the fixed frame is fixedly connected to a connecting frame, and one side of the bottom of the connecting frame is fixedly connected to a supporting plate. The top of the supporting plate is equipped with a washing component for flushing the boiler’s inner wall and reducing dust.

Optionally, the grinding component includes a drive motor arranged on the bottohJ508522 surface of the fixed frame, which is located adjacent to the positioning plate. The output end of the drive motor is fixedly connected to a first gear shaft, the surface of the first gear shaft is fitted with a belt, and the inner side of the belt is fitted with a second gear shaft. Both the first and second gear shafts are fixedly connected to connecting rods.

Optionally, one end of the connecting rod penetrates the interior of the positioning plate and is fixedly connected to a disk base. The surface of the disk base is equipped with a wire circle for removing stubborn dirt from the filtered inner wall.

Optionally, the washing component includes a water tank arranged on the top of the supporting plate, one side of the top of the water tank is equipped with a high-pressure water pump, one end of the high-pressure water pump is connected to an L-pipe, one end of the L-pipe is connected to the interior of the water tank, and the top of the high-pressure water pump is connected to a hose, one end of which is connected to a transverse pipe.

Optionally, the side of the transverse pipe is sequentially connected to several connecting pipes at equal intervals from left to right, and one end of the connecting pipes is connected to a high-pressure nozzle.

Optionally, the inner top surface of the connecting frame is equipped with a top plate, and several directional holes are evenly spaced along the surface of the top plate from left to right, with high-pressure nozzles fitted within the directional holes.

Optionally, connecting plates are arranged at the four corners of the back of the fixed frame, and one end of the connecting plates is movably connected to wheels.

By adopting the above technical solution, the present invention has the following beneficial effects compared to existing technology. However, implementing any product of the present invention does not necessarily require achieving all the advantages described below simultaneously:

With the arrangement of the grinding component and washing component, when workers clean the boiler's inner wall, they can move the device into the boiler and connect the drive motor to an external power source. This drives the first gear shaftU508522 which in turn rotates the belt, leading to the rotation of the second gear shaft. This rotation drives the connecting rods simultaneously, which then drive the disk base and wire circle. The wire circle contacts the boiler’s inner wall and, as the device is moved, continuously grinds away the stubborn dirt on the boiler’s inner wall, thus improving the efficiency of the cleaning process. While grinding the stubborn dirt on the boiler’s inner wall, the high-pressure water pump can be connected to an external power source to extract water from the water tank through the L-pipe. The water is then conveyed through the hose and transverse pipe into the connecting pipes, spraying out from the high-pressure nozzle. This allows for simultaneous grinding and removal of stubborn dirt while flushing away the dust generated by the grinding, thereby further enhancing the efficiency of boiler cleaning.

The following provides a more detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION LU508522

It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but rather to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments.

Referring to Figures 1-4, this embodiment provides a cleaning device for the inner wall of a boiler used in thermal power generation. The device includes:

Fixed Frame (1): One side of the inner bottom surface of the fixed frame (1) is fixedly connected to a Positioning Plate (2). On the inner bottom surface of the fixed frame (1), on the side adjacent to the positioning plate (2), there is a Grinding Component (3) designed to remove stubborn dirt from the boiler’s inner wall.

When staff are cleaning the boiler’s inner wall, they can move this device into the boiler and connect the Drive Motor (31) to an external power supply. This motor drives the

First Gear Shaft (32), which in turn rotates the Belt (33). The movement of the belt causes the Second Gear Shaft (34) to rotate, which drives the Connecting Rod (35). The connecting rod simultaneously rotates the Disk Base (36) and the Wire Circle (37). The wire circle (37) makes contact with the boiler's inner wall, continuously grinding away the stubborn dirt as the device is moved, thereby improving the efficiency of the cleaning process.

The surface of the fixed frame (1) is fixedly connected to a Connecting Frame (4).

One side of the bottom of the connecting frame (4) is fixedly connected to a Supporting

Plate (5), and the top of the supporting plate (5) is equipped with a Washing Component (6), which is used for flushing the boiler’s inner wall and reducing dust.

In one aspect of this embodiment, while grinding away the stubborn dirt from the boiler's inner wall, the High-Pressure Water Pump (62) can be connected to an external power supply. This pump draws water from the Water Tank (61) through the L-Pipe (63) and delivers it through the Hose (64) and Transverse Pipe (65) into the Connecting Pipe (66), where it is then sprayed out from the High-Pressure Nozzle (67). This setup allows for simultaneous grinding and flushing, which helps to clear away the dust producdd)508522 during the cleaning process, further enhancing the efficiency of the boiler cleaning.

It is important to note that all electrical equipment mentioned in this application can be powered either by a battery or an external power supply.

As shown in Figure 2, the inner top surface of the Connecting Frame (4) is equipped with a Top Plate (7), which has several Directional Holes evenly spaced from left to right.

Inside these directional holes, the High-Pressure Nozzle (67) is fitted, ensuring that the nozzle is fixed in place and directing the spray toward the boiler's inner wall, thus improving flushing efficiency.

As depicted in Figure 1, at each corner of the back of the Fixed Frame (1), there are

Connecting Plates. One end of each connecting plate is movably connected to a Wheel (8), which facilitates the mobility of the device.

Embodiment 1

In this embodiment, as shown in Figure 4, the Grinding Component (3) includes a

Drive Motor (31) positioned on the inner bottom surface of the Fixed Frame (1), adjacent to the Positioning Plate (2). The output end of the drive motor (31) is fixedly connected to a First Gear Shaft (32). A Belt (33) is fitted onto the surface of the first gear shaft (32), and inside this belt, there is a Second Gear Shaft (34). Both the first gear shaft (32) and the second gear shaft (34) are fixedly connected to a Connecting Rod (35). One end of the connecting rod (35) passes through the interior of the positioning plate (2) and is fixedly connected to a Disk Base (36). The surface of the disk base (36) is equipped with a Wire

Circle (37), designed to remove stubborn dirt from the inner wall. When staff are cleaning the boiler's inner wall, they can move this device into the boiler and connect the drive motor (31) to an external power supply. The motor then drives the first gear shaft (32), which rotates the belt (33). This movement causes the second gear shaft (34) to rotate, which in turn drives the connecting rod (35). As the connecting rod rotates, it simultaneously rotates the disk base (36) and the wire circle (37).

The wire circle (37) makes contact with the boiler’s inner wall and, as the device is/508522 moved, it continuously grinds away the stubborn dirt on the boiler's inner wall. This grinding action significantly improves the efficiency of the boiler wall cleaning process.

Embodiment 2

In this embodiment, as shown in Figure 3, the Washing Component (6) includes a

Water Tank (61) positioned at the top of the Support Plate (5). On one side of the top of the water tank (61), there is a High-Pressure Water Pump (62). One end of the high-pressure water pump (62) is connected to an L-Pipe (63), which penetrates into the interior of the water tank (61). The top of the high-pressure water pump (62) is connected to a Hose (64), and one end of this hose (64) is connected to a Cross Pipe (65). The side of the cross pipe (65) is equipped with several Connecting Pipes (66) that are evenly spaced and run from left to right. One end of each connecting pipe (66) is connected to a

High-Pressure Nozzle (67). When grinding away stubborn dirt on the boiler’s inner wall, the high-pressure water pump (62) can be connected to an external power supply. The pump draws water from the interior of the water tank (61) through the L-pipe (63) and transports it through the hose (64) and the cross pipe (65) into the connecting pipes (66).

The water is then sprayed out through the high-pressure nozzle (67).

This setup allows for simultaneous grinding and flushing, effectively removing stubborn dirt from the boiler’s inner wall while washing away the dust generated from the grinding process, thereby further enhancing the efficiency of the boiler cleaning operation.
