Description

Technical Field

[0001] This utility model relates to the technical field of belt conveyors, specifically to an online cleaning device for scale buildup in belt conveyor discharge chutes. Background Technology

[0002] In industries such as metallurgy, mining, cement, and chemicals, belt conveyor chutes often transport materials with high moisture content, high viscosity, or easy solidification (such as mineral powder, coal slime, clay, etc.). These materials tend to adhere to and accumulate on the inner wall of the chute, gradually forming scale (commonly known as "material blockage"), which reduces the flow cross-sectional area or even causes complete blockage.

[0003] The problem of scale buildup in the conveyor belt feed chute forces the production line to stop frequently for manual cleaning, which seriously affects the continuous production rhythm, resulting in capacity loss and reduced equipment utilization. Manual cleaning requires entering the enclosed chute, which poses safety risks such as falls from heights, dust explosions, and toxic gases. Scale falling off may also cause equipment jamming or belt misalignment.

[0004] Traditional cleaning relies on manual labor, requiring machine shutdown and workers to hammer and scrape, which is time-consuming, has inconsistent results, is inefficient, and labor-intensive. Fixed unblocking devices, such as vibrators and air cannons, can only solve local blockages and have limited effectiveness on large-area scaling. Existing chutes mostly rely on increasing the inclination angle or lining with wear-resistant materials to delay scaling, but cannot fundamentally solve the problem. This research and development direction is an inevitable choice to solve the industry's pain points.

[0005] Therefore, we propose an online cleaning device for scale buildup in conveyor belt discharge chutes to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide an online cleaning device for scale buildup in conveyor belt discharge chutes, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an online cleaning device for scale buildup in a conveyor belt chute, comprising a feeding conveyor belt, a discharge chute installed on the right side of the feeding conveyor belt, a receiving belt installed at the bottom of the discharge chute, a movable belt curtain installed near the upper right side of the inner cavity of the discharge chute, and an air cannon installed near the bottom of the right side of the discharge chute.

[0008] Preferably, an opening is provided on the right side of the discharge chute near the top, and the top of the movable belt curtain passes through the opening and extends to the outside of the discharge chute.

[0009] Preferably, the air cannon is connected to the back of the movable belt curtain via a metal pipe and a discharge chute.

[0010] Preferably, the movable belt curtain is installed in the area of ​​the material chute where scaling is likely to occur, thus preventing wear on the chute and preventing material blockage.

[0011] Preferably, the top of the movable belt curtain is fixed to the discharge chute, forming a natural downward suspension within the discharge chute.

[0012] Preferably, the operation of the air cannon can provide a power source for the movable belt curtain, and the air cannon can vibrate and clean the movable belt curtain to remove surface scale and clumps.

[0013] Preferably, the receiving belt can transport the unloaded material and prevent it from accumulating below the unloading chute.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] An online cleaning device consisting of a suspended movable belt curtain and an air cannon is used at the material discharge chute of the feeding belt conveyor where scale is prone to form. The belt curtain is suspended in the chute, and the scale formed on the belt curtain by the material is vibrated by the air cannon behind the belt curtain, causing the scale blocks on the movable belt curtain to fall off to the receiving belt, thus achieving a whole-surface scale cleaning effect.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 An online cleaning device for scale buildup in a conveyor belt chute includes a feeding conveyor belt 1, a discharge chute 2 installed on the right side of the feeding conveyor belt 1, a receiving belt 5 installed at the bottom of the discharge chute 2, a movable belt curtain 3 installed near the upper right side of the inner cavity of the discharge chute 2, and an air cannon 4 installed near the bottom of the right side of the discharge chute 2.

[0020] An opening is provided on the right side of the discharge chute 2 near the top, and the top of the movable belt curtain 3 passes through the opening and extends to the outside of the discharge chute 2.

[0021] The air cannon 4 is connected to the back of the movable belt curtain 3 via a metal pipe and the discharge chute 2.

[0022] The movable belt curtain 3 is installed in the inner cavity of the material chute 2 where it is prone to scaling, and has the functions of preventing wear on the chute and preventing material blockage.

[0023] The top of the movable belt curtain 3 is fixed to the discharge chute 2, forming a natural downward suspension within the discharge chute 2.

[0024] The operation of the air cannon 4 can provide a power source for the movable belt curtain 3. The air cannon 4 can vibrate and clean the movable belt curtain 3 to remove surface scale and clumps.

[0025] The receiving belt 5 can transport the unloaded material and prevent it from accumulating below the unloading chute 2.

[0026] In this embodiment: During production operation, scale is generated on the movable belt curtain 3. The air cannon 4 is activated online to vibrate the movable belt curtain 3, causing the scale blocks on the surface of the movable belt curtain 3 to fall off to the receiving belt 5, thus achieving the purpose of online cleaning.

[0027] Working principle: During use, the material is conveyed to the right by the operation of the feeding belt conveyor 1. When the material is conveyed to the right, it falls into the receiving belt 5 through the discharge chute 2. The receiving belt 5 can convey the material. When the material forms a sludge due to adhesion and accumulation in the discharge chute 2, the air cannon 4 needs to be activated to vibrate the movable belt curtain 3. The vibration can make the sludge on the surface of the movable belt curtain 3 fall off onto the receiving belt 5, which plays a cleaning role and avoids the reduction of the flow cross-sectional area or even complete blockage.

[0028] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
