Description

Technical Field

[0001] This utility model relates to the field of cement production technology, specifically to an anti-blocking device for a belt conveyor. Background Technology

[0002] The cement industry currently uses a large amount of powdered materials as raw materials, especially some industrial by-products and tailings powder. These materials are characterized by their powdery form and the presence of a certain amount of moisture. After prolonged storage or during rainy seasons and winters, the moisture does not easily evaporate. Because they are mostly stored in warehouses, the high moisture content can easily lead to clumping or caking due to compression. This can cause various blockages during use, affecting normal production. Currently, there are many ways to address this problem, but their effectiveness is not entirely satisfactory.

Detailed Implementation

[0020] 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.

[0021] like Figure 1-2 As shown, this utility model provides a technical solution: a belt conveyor anti-blocking device, characterized in that: it includes a belt conveyor, the belt conveyor includes a frame 1 and a rotatable conveyor belt 2 (and also includes a drive motor, drive sprocket, etc., which are within the scope of prior art), the top of the belt conveyor is covered with a sealing cover 3 (with raw material inlets and outlets on both sides), and the sealing cover 3 is located directly above the conveyor belt 2.

[0022] The sealing cover 3 is equipped with two sets of rotatable dispersing rollers 4, and the rotation direction of the dispersing rollers 4 is as follows: Figure 2 As shown, Figure 1 The central sealing cover 3 is a cross-sectional view. To facilitate the display of the position of the dispersing roller 4 inside the sealing cover 3, the two sets of dispersing rollers 4 are staggered. The dispersing roller 4 is driven by an external motor and is set horizontally inclined (this design is intended to facilitate the discharge of raw materials with high hardness). The inclination angle is 30-45 degrees. A discharge port 5 is provided on one side of the sealing cover 3. The discharge port 5 can be designed as an inclined step to facilitate material discharge.

[0023] A suction hopper 15 is installed on the top of the sealing cover 3, and a storage box 13 is provided on the side of the sealing cover 3. An industrial vacuum cleaner 14 is installed on the top of the storage box 13. The industrial vacuum cleaner 14 is connected to the suction hopper 15 through a suction hose 16. For the dust generated during the dispersing process, the industrial vacuum cleaner 15 is turned on, and the dust in the sealing cover 3 is sucked into the storage box 13 through the suction hopper 15 and the suction hose 16 for storage. There is a waste discharge port at the bottom of the storage box 13 (not shown in the figure), and the waste can be discharged periodically.

[0024] The discharge plate 6 is located below the discharge port 5. Side baffles 17 are provided on both sides of the discharge plate 6. The purpose of the side baffles 17 is to prevent raw materials from falling and to prevent materials from slipping. A crushing box 7 is provided below the discharge plate 6. The top of the crushing box 7 has a feed inlet 71. Two rotatable crushing rollers 8 are installed inside the crushing box 7 (which crush raw materials by the crushing pressure generated by rotation). The crushing rollers 8 are driven by an external crushing motor 9.

[0025] Bucket elevator 10 (existing technology equipment) is connected to the bottom outlet of crushing box 7 through receiving pipe 11. A discharge pipe 12 is installed at the top outlet of bucket elevator 10, and the outlet of discharge pipe 12 is located above conveyor belt 2.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] In use, the powdered cement raw material is conveyed by a belt conveyor. During the conveying process, the raw material enters the sealed cover 3 and is driven by an external motor to rotate the dispersing roller 4, thereby dispersing the raw material. The dispersed raw material is discharged from the other side of the sealed cover 3 and enters the next process. The dispersing of the raw material greatly reduces the clogging problem.

[0028] For raw materials that are hard and difficult to break down, they can be conveyed out by the inclined breaking roller 4. The raw materials are fed into the crushing box 7 through the discharge plate 6. The crushing motor 9 is turned on, which drives the crushing roller 8 to rotate, thereby crushing the hard raw materials. The crushed raw materials enter the bucket elevator 10 through the receiving pipe 11. After being lifted by the bucket elevator 10, they are discharged from the discharge pipe 12 onto the conveyor belt 2 and enter the conveying process again.

[0029] In summary, this belt conveyor anti-blocking device, by setting up a dispersing and unblocking mechanism in the conveying process of powdered cement raw materials, can disperse the lumpy materials before conveying them. It can also promptly remove lumps that are difficult to disperse due to their high hardness, and then crush them through a crushing mechanism before finally incorporating them into the conveying structure, thereby achieving the purpose of rapid and efficient unblocking.
