Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust removal, in particular to a dust removal pipe with a sight glass. Background Art
[0002] Ambient dust collectors are commonly used in dust removal applications in industries like cement and metallurgy. Most ash discharge equipment connected to the ash hopper's lower outlet is equipped with electric valves, such as star-shaped valves, to control the discharge flow and speed. However, dust entering the hopper inevitably contains large pieces of debris or materials. If these particles enter the valve's impeller, they can overload the valve and potentially damage the motor. This can affect equipment operation and hinder production efficiency; it can also increase maintenance costs and cause unnecessary losses. Utility Model Content
[0003] The embodiment of the utility model provides an ash discharge pipe with a sight glass, which has the technical effect of preventing debris and large pieces of material from entering the ash discharge valve and being able to observe the dust entering the inside of the pipe body.
[0004] A dust discharge pipe with a sight glass adopts the following technical solution:
[0005] A dust discharge pipe with a sight glass comprises a gate valve, a pipe body and the dust discharge valve. The pipe body is connected between the gate valve and the dust discharge valve. A stainless steel wire mesh is fixed to the inner wall of the pipe body on the side close to the dust discharge valve. A sight glass assembly is installed on the side wall of the pipe body and is located above the stainless steel wire mesh.
[0006] The sight glass assembly includes a sight glass tube, glass and a clamping ring. The sight glass tube is fixed on the outer wall of the tube body. A sight glass flange is fixed on the end of the sight glass tube away from the tube body. The glass is installed between the sight glass flange and the clamping ring. The sight glass flange and the clamping ring are fixed by a bolt group. When unloading dust, the dust unloading situation inside the tube body can be observed through the glass. When the tube body is blocked, it is necessary to open the sight glass in time and remove the debris.
[0007] Furthermore, grooves are provided on the sides of the sight glass flange and the clamping ring that are close to each other, and sight glass sealing gaskets are installed in the grooves, and the glass is located between the two sight glass sealing gaskets.
[0008] Furthermore, a rotating rod is installed at the center of the glass. The rotating rod passes through the glass. A scraper is fixed to one end of the rotating rod. The scraper is located in the pipe body and contacts the inner wall of the glass. A shift rod is fixed to the end of the rotating rod away from the scraper.
[0009] Furthermore, the upper flange of the gate valve is connected to the lower ash outlet flange of the dust collector ash hopper by bolts, and a sealing gasket is provided at the flange connection.
[0010] Furthermore, an upper flange of the connecting pipe is fixed to the top of the connecting pipe body, and a lower flange of the connecting pipe is fixed to the bottom of the connecting pipe body. The upper flange of the connecting pipe is fixed to the lower flange of the gate valve by bolts, and the lower flange of the connecting pipe is fixed to the upper flange of the ash discharge valve by bolts, and sealing gaskets are provided at the flange connections.
[0011] Compared with the prior art, the present invention has the following technical effects:
[0012] The utility model has the characteristics of intercepting debris, realizing online observation, facilitating maintenance, extending the service life of the equipment and reducing maintenance costs. When the inside of the glass is covered with dust, the lever is rotated and the scraper can rotate along the center of the glass to clean the inner wall of the glass. Workers can clearly observe the internal situation of the pipe body from the outside. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the schematic embodiments of the present invention and their description are used to explain the present invention, but are not intended to limit the present invention.
[0019] Embodiment 1 of the present utility model
[0020] Reference Figure 1 and Figure 2A dust discharge pipe with a sight glass includes a gate valve 1, a pipe body 3, a dust discharge valve 7, and a sight glass assembly 4. The upper flange of the gate valve 1 is bolted to the flange at the lower ash outlet of the dust collector hopper. The top of the pipe body 3 is fixed with an upper pipe flange 2, and the bottom of the pipe body 3 is fixed with a lower pipe flange 6. The lower flange of the gate valve 1 and the upper pipe flange 2 are also bolted together. Sealing gaskets are installed at the flange connections to ensure the valve is sealed and prevent dust leakage.
[0021] The lower flange 6 of the pipe is bolted to the upper flange of the ash discharge valve 7. The lower flange of the ash discharge valve 7 is also bolted to the flange of the downstream ash conveying equipment. Gaskets are installed at the flange joints to ensure a leak-proof valve seal. A stainless steel mesh 5 is installed inside the pipe body 3, near the lower flange 6. The mesh is welded to the inner wall of the pipe body 3. The wear-resistant and corrosion-resistant mesh intercepts large debris and breaks up agglomerated dust, thereby protecting downstream equipment.
[0022] The mirror assembly 4 is mounted on the side wall of the pipe body 3 and is located above the stainless steel mesh 5. The mirror assembly 4 includes a mirror pipe 401, a mirror flange 402, and a glass 404. One end of the mirror pipe 401 is welded to the outer wall of the pipe body 3, and the other end of the mirror pipe 401 is welded to the mirror flange 402. A clamping ring 405 is provided on the side of the mirror flange 402 away from the mirror pipe 401, and the glass 404 is located between the mirror flange 402 and the clamping ring 405. The mirror flange 402 and the clamping ring 405 are fixed by a bolt group 406. A groove is formed on the side where the mirror flange 402 and the clamping ring 405 are close to each other, and a mirror sealing gasket 403 is installed in each groove. The glass 404 is located between the two mirror sealing gaskets 403. Glass 404 is tempered borosilicate glass, which has the characteristics of high temperature resistance, high strength, high hardness and high light transmittance, and can better ensure the observation effect of the viewfinder.
[0023] The working principle of the dust removal pipe with a sight glass of the present invention is as follows: dust in the dust collector passes through the gate valve 1 and enters the pipe body 3. Large debris is intercepted by the stainless steel wire mesh 5 and broken up when passing through the stainless steel wire mesh 5. The staff can observe the dust in the pipe body 3 through the glass 404. If the pipe body 3 is found to be blocked, it can be repaired in time. When not unloading dust, the glass 404 can also be opened to clean out debris remaining in the pipe.
[0024] Embodiment 2 of the present utility model
[0025] Reference Figure 3A rotating rod 8 is mounted at the center of the glass 404, passing through the glass 404. A scraper 801 is fixed to one end of the rotating rod 8. The scraper 801 is located within the pipe body 3 and contacts the inner wall of the glass 404. A lever 802 is fixed to the end of the rotating rod 8 away from the scraper 801. Rotating the lever 802 causes the scraper 801 to rotate along the center of the glass 404, cleaning the inner wall of the glass 404 and keeping it clean. This allows staff to clearly observe the interior of the pipe body 3 from the outside.
[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
