Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, specifically a premixing device for a mixed material belt conveyor. Background Technology

[0002] In existing technologies, after the raw materials are combined in the sintering batching room of a steel plant, they need to be mixed and granulated using primary and secondary mixers. The original two-stage mixing method often results in insufficient mixing of the raw materials due to changes in their structure. This causes fluctuations in the moisture content, carbon content, and chemical composition of the sinter during sintering, increasing the amount of sintered powder returned and raising costs. Furthermore, insufficient mixing can lead to particle size segregation in the granulated pellets, affecting the stability of the sintering machine's material distribution and requiring manual adjustments, increasing the workload of workers. Utility Model Content

[0003] The purpose of this invention is to provide a premixing device for a mixing conveyor belt that allows for early material turning, addressing the aforementioned shortcomings.

[0004] The technical solution of this utility model is: a premixing device on a mixing conveyor belt, including a frame spanning the conveyor belt, an adjusting screw in the middle of the frame, the adjusting screw being connected to a V-shaped material distribution plate, and a hydraulic push rod connected behind the V-shaped material distribution plate to open and close it.

[0005] The above plan also includes:

[0006] The V-shaped material distribution plate consists of two side plates connected to an adjusting screw via bushings.

[0007] The hydraulic push rod consists of a central hydraulic cylinder and two telescopic piston rods on both sides, which are movably connected to the back of the V-shaped material distribution plate.

[0008] The hydraulic push rod is connected to the hydraulic oil pump via a pipeline.

[0009] The adjusting screw has an arc-shaped section in the middle.

[0010] The frame is a door frame.

[0011] The advantages of this invention are: 1. By installing a V-shaped distribution plate on the belt conveyor, the material is plowed before entering the mixer, and the material rolls outward on the belt, achieving pre-mixing of the raw materials, improving the mixing efficiency, promoting the improvement of sinter quality, increasing the stability of the chemical composition of sinter, and reducing the labor intensity of workers. 2. The height and width of the V-shaped distribution plate are adjustable, thereby achieving the purpose of pre-mixing the raw materials on the mixing belt conveyor, improving the mixing efficiency, and promoting the improvement of sinter quality.

[0012] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0013] Figure 1 This is a simplified structural diagram of the present invention.

[0014] Figure 2 This is a simplified diagram of the connection structure of the adjusting screw, V-shaped material distribution plate, and hydraulic push rod components.

[0015] The components in the diagram are named as follows: Frame 1, Adjusting screw 2, V-shaped material distribution plate 3, Hydraulic push rod 4, Belt conveyor belt 5, Pipeline 6, Hydraulic oil pump 7, Arc section 8, Arrow for belt running direction 9, Belt conveyor frame 10, Adjusting nut 11. Detailed Implementation

[0016] See Figure 1 , 2 A premixing device for a mixing conveyor belt includes a frame 1 spanning the conveyor belt 5, which is a door frame. A vertical adjusting screw 2 is located in the middle of the frame 1, with an arc-shaped section 8 in the middle. This section acts as a buffer when material impacts a V-shaped distribution plate 3 or when hard objects in the material impact the V-shaped distribution plate 3, preventing the device from deforming and becoming ineffective. The adjusting screw 2 is connected to the V-shaped distribution plate 3. Moving the adjusting screw 2 up and down causes the V-shaped distribution plate 3 to move up and down, adjusting the distance between the V-shaped distribution plate 3 and the conveyor belt 5. The V-shaped distribution plate 3 is movably connected to the adjusting screw 2 via bushings on both sides. A hydraulic push rod 4 is connected to the V-shaped distribution plate 3 to open and close it. The hydraulic push rod 4 consists of a central hydraulic cylinder and two retractable piston rods on both sides. The retractable piston rods on both sides are movably connected to the back of the V-shaped distribution plate 3, causing the two sides of the V-shaped distribution plate 3 to open and close around the adjusting screw 2, thereby adjusting the plowing angle of the V-shaped distribution plate 3. The hydraulic push rod 4 is connected to the hydraulic oil pump 7 via the pipeline 6.

[0017] This device is installed on the mixing belt conveyor before entering the primary mixer. The V-shaped distribution plate 3 (plow-type distributor) in the device is used to premix the raw materials distributed on the mixing belt. Under the action of the belt speed, the material rolls outward on the belt 5 of the belt conveyor, thereby achieving premixing of the raw materials, improving the mixing efficiency of the raw materials, and promoting the improvement of sinter quality.

[0018] After the device is installed on the mixing conveyor belt, the depth of the plowing is adjusted by adjusting the buffer crank (with the arc section 8 in the middle) and the overall height by adjusting the screw 2 according to the material feed rate and the material thickness on the conveyor belt. Then, according to the width of the material flow on the conveyor belt, the opening and closing angle of the V-shaped material distribution plate 3 (turning steel plate) is adjusted by the hydraulic device to adjust the width of the plowing. In this way, the device can premix the raw materials on the mixing conveyor belt, improve the mixing efficiency, and promote the improvement of sinter quality.

[0019] The above description is merely a specific embodiment of this utility model, and the various examples do not constitute a limitation on the substantive content of this utility model.
