Description

Technical Field

[0001] The utility model belongs to the field of slag scooping machines, and in particular relates to a floating bead cleaning device for a water-immersed scraper slag scooping machine. Background Art

[0002] At present, most of the boiler slag removal equipment of thermal power companies adopts water-immersed scraper slag removers. The slag that needs to be processed falls directly into the water in the trough of the slag remover. The slag will be cooled and granulated in the water, and then scraped into the slag bin by the scraper.

[0003] During the combustion of coal powder, clayey substances will melt into tiny droplets, which will spin at high speed under the turbulent hot air in the furnace to form round silicon-aluminum spheres. Gases such as nitrogen, hydrogen and carbon dioxide produced by combustion and cracking reactions will expand rapidly in the molten high-temperature silicon-aluminum spheres, forming hollow glass bubbles under the action of surface tension. After the glass bubbles harden, they will become high-vacuum glass hollow microspheres, i.e. floating beads, which will fall into the slag scoop machine together with the slag and float on the cooling water surface of the slag scoop machine.

[0004] The density of the floating beads is relatively small, so they will float on the surface of the water and flow into the overflow tank and overflow pipe of the slag scoop machine. If they are not cleaned in time, the accumulation of floating beads will lead to blockage of the overflow pipe, further causing the slag scoop machine to be unable to continue to overflow.

[0005] The floating beads that drift into the ditches and pits will gradually accumulate, causing siltation in the ditches and pits, affecting the safe operation of the unit.

[0006] However, when the unit is running, the slag will continuously fall into the slag remover, which will cause great inconvenience to the cleaning of the floating beads. Therefore, the current cleaning of the floating beads can only be done when the unit is shut down, which is inconvenient and unsafe.

[0007] Therefore, a new design specifically for cleaning the floating beads in the slag scooping machine is needed. Utility Model Content

[0008] In view of the above problems existing in the prior art, the purpose of the utility model is to provide a floating bead cleaning device for a water-immersed scraper slag remover.

[0009] In order to solve the above problems, the technical solution adopted by the utility model is as follows:

[0010] A floating bead cleaning device for a water-immersed scraper slag scoop comprises a shell, a filter screen and a cleaning port, wherein the shell is provided with a water inlet and a water outlet, the water inlet is connected to an overflow trough of the slag scoop, the filter screen is arranged inside the shell, the filter screen is provided with a rotating shaft extending out of the shell in a direction perpendicular to the water inlet, a rotating component is provided at one end of the rotating shaft extending out of the shell, and an openable and closable cleaning port is provided on the shell.

[0011] The shell is spherical, the water inlet is arranged on the side of the shell, and the water outlet is arranged on the bottom of the shell.

[0012] The filter screen is a circular filter screen, and a plurality of circular filter screens are provided and combined with the center as the intersection point.

[0013] The circular filter screens are provided with two and are combined in a cross shape.

[0014] The cleaning port is arranged at the upper half of the side opposite to the water inlet.

[0015] The rotating component is a rotating handle, and the rotating handle is an anti-slip handle.

[0016] The rotating component is a cross-shaped rotating block.

[0017] The rotating block is provided with a rotating scale groove for positioning.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The utility model has a simple structure and is easy to deploy. During installation, it is directly installed at the outlet of the overflow trough of the slag scooping machine. Water with floating beads enters the cleaning device from the water inlet of the cleaning device shell, and then the filter screen in the shell intercepts the floating beads, and cooling water flows out from the water outlet of the cleaning device.

[0020] After a period of filtration, the filter screen of the cleaning device needs to be cleaned. At this time, open the cleaning port on the outer shell, and then rotate the filter screen through the shaft to rotate the filter screen that intercepts the floating beads to the position of the cleaning port, clean out the intercepted floating beads, and close the cleaning port after cleaning to complete the cleaning process. The whole process does not require shutdown, and the filter screen is composed of multiple structures with the center as the intersection. Even when cleaning, the filter screen on the other side will continue to intercept the floating beads, which will not affect the normal operation of the slag remover.

[0025] The utility model is further described below in conjunction with specific embodiments.

[0026] Example 1

[0027] like Figure 1 , Figure 2 As shown, the utility model mainly includes a shell 1 and an internal filter screen 2.

[0028] The structure of the outer shell 1 is a hollow sphere, with a water inlet 3 on the horizontal side of the outer shell 1 and a water outlet 4 at the bottom of the outer shell 1. The water inlet 3 is connected to the overflow trough or overflow pipe of the slag scoop machine. The floating beads generated in the slag scoop machine will flow from the overflow trough or overflow pipe into the outer shell 1 of the cleaning device along with the water flow.

[0029] Inside the housing 1 , a rotating shaft 5 penetrating the housing 1 is arranged in a horizontal direction perpendicular to the water inlet 3 , and the filter screen 2 is arranged on the rotating shaft 5 .

[0030] The filter screen 2 is a combination of multiple small filter screens, wherein the small filter screen is a circular filter screen, which is approximately the same size as the inner diameter of the outer shell 1 and can completely cover the inner cross section of the spherical outer shell 1 without affecting the flipping of the small filter screen. The multiple small filter screens are fixedly connected to each other in a common diameter manner. The number of small filter screens can be freely selected, but in this embodiment, the number of small filter screens selected for the structure used for demonstration is two, which are cross-connected together. The diameter position of the connection point is where the rotating shaft 5 passes through and can control the rotation of the filter screen 2. If Figure 2 shown in cross section.

[0031] At the upper hemisphere on one side of the water inlet 3 of the shell 1, there is a gap of about a quarter of the shell 1, which is the cleaning port 7 of the cleaning device. A cleaning door is also provided on the outside of the cleaning port 7 to close it.

[0032] The length of the rotating shaft 5 runs through the entire housing 1 and extends to the outside of the housing 1 . A rotating handle 6 is connected to the end of the rotating shaft 5 . By shaking the rotating handle 6 , the rotation of the filter screen 2 inside the housing 1 can be controlled.

[0033] After the cleaning device has been running for a period of time, it is necessary to clean the floating beads intercepted in the cleaning device. The small filter screen on one side of the filter screen 2 that intercepts the floating beads can be rotated to the position of the cleaning port 7 by rotating the handle 6, and then the cleaning door of the cleaning port 7 is opened to clean the floating beads on the filter screen 2.

[0034] During the whole process, the slag remover does not need to be shut down and can cool the slag normally. In addition, combined with the cross structure of the filter 2, even when the small filter is cleaned, the small filter on the opposite side will intercept the floating beads, which will not affect the normal operation of the entire cleaning device.

[0035] Example 2

[0036] The structure of this embodiment is exactly the same as that of the embodiment 1, except that the structure for controlling the rotation of the rotating shaft 5 is connected to the end of the rotating shaft 5 .

[0037] In the first embodiment, the rotating handle 6 connected to the end of the rotating shaft 5 is relatively long and may not be able to complete a normal rotation in a relatively narrow place. Therefore, in this case, the rotating handle 6 can be replaced by a cross-shaped rotating block 8, such as Figure 3 As shown, the space required for the shaft to rotate one circle is greatly reduced, making it more suitable for deploying the cleaning device in places with limited space.

[0038] And according to the style of the rotating block 8, a corresponding scale groove can also be set on the internal rotating shaft 5. When the rotating block 8 rotates to the specified position, it can give the user a more obvious stop, prompting the user that the filter 2 has been rotated to the specified position to prevent over-rotation.

[0039] The design of the scale groove is not limited to the rotating block 8, and can also be used in the rotating handle structure in Example 1.
