Description

Technical Field

[0001] This utility model relates to the technical field of magnesium-carbon brick mixing machines, and in particular to a feeding hopper for a magnesium-carbon brick mixing machine. Background Technology

[0002] Magnesia-carbon bricks are made from high-melting-point alkaline oxide magnesium oxide (melting point 2800℃) and high-melting-point carbon materials that are difficult to be wetted by slag, with the addition of various non-oxide additives. During the processing of magnesia-carbon bricks, the powder is mixed in a mixer, which is equipped with a feed hopper for feeding the material into the mixer.

[0003] Magnesium carbon brick mixers are equipped with hoppers during feeding. Conventional hoppers have a simple structure, being a bowl-shaped vessel that is wider at the top and narrower at the bottom with a hollow interior. When materials are fed, they are quantitatively fed into the mixer through a hollow cavity of a fixed size. When a reduced feeding is required, the fixed-size cavity cannot meet the need to change the amount of material fed. Utility Model Content

A positioning hole for mounting the fixing frame with screws is vertically passed through the end wall of the fixing frame. A middle cavity for conveying magnesia-carbon brick processing powder is opened in the lower hopper. A lower cavity for conveying magnesia-carbon brick processing powder is opened in the lower hopper. A sliding opening communicating with the middle cavity is obliquely passed through the left end wall of the middle hopper. A rectangular sliding plate extending into the middle cavity is movably connected in the sliding opening.

[0007] Preferably, a screw is threadedly connected to the front wall of the middle bucket near the sliding opening. Tightening the screw is used to lock and limit the sliding plate that is movably connected in the sliding opening.

[0008] Preferably, the top wall of the middle hopper near the middle cavity is provided with a magnetic wall, and a magnetic disk is connected to the magnetic wall.

[0009] Preferably, the magnetic disk is rectangular, and a rectangular upper bucket with a size larger than the middle bucket is fixed to the top wall of the magnetic disk.

[0010] Preferably, the upper bucket has a rectangular cavity.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a feeding hopper for a magnesia-carbon brick mixer:

[0022] like Figure 1-4As shown, a feeding hopper for a magnesia-carbon brick mixer includes a rectangular middle hopper 1. A lower hopper 2, which is wider at the top and narrower at the bottom, is fixed to the lower end wall of the middle hopper 1. An L-shaped fixing frame 3 is fixed to the side wall of the lower hopper 2. A positioning hole 4 for mounting the fixing frame 3 through a vertical hole is provided on the end wall of the fixing frame 3. A middle cavity 5 for conveying magnesia-carbon brick processing powder is provided inside the lower hopper 2. A lower cavity 6 for conveying magnesia-carbon brick processing powder is provided inside the lower hopper 2. A sliding opening 7, which is inclined and communicates with the middle cavity 5, is provided on the left end wall of the middle hopper 1. A rectangular sliding plate 9, which extends into the middle cavity 5, is movably connected to the sliding opening 7.

[0023] A screw 8 is threadedly connected to the front wall of the middle bucket 1 near the sliding opening 7. Tightening the screw 8 is used to lock and limit the sliding plate 9 that is movably connected in the sliding opening 7. A magnetic wall 10 is provided on the top wall of the middle bucket 1 near the middle cavity 5. A magnetic disk 11 is connected to the magnetic wall 10.

[0024] The magnetic disk 11 is rectangular, and a rectangular upper hopper 12 with a size larger than the middle hopper 1 is fixed to the top wall of the magnetic disk 11. A rectangular hopper cavity 13 is provided inside the upper hopper 12.

[0025] A guide port 14 is provided at the end wall of the magnetic disk 11, extending into the upper bucket 12 and communicating with the bucket cavity 13;

[0026] Working principle:

[0027] Bolts or screws are inserted through the positioning holes 4 of the fixed frame 3 to position and install the fixed frame 3 at the mixing end wall.

[0028] The middle chamber 5 and lower chamber 6 of the middle hopper 1 and lower hopper 2 are used for conveying magnesia-carbon brick powder. The powder flows from the middle chamber 5 into the lower chamber 6, and then from the bottom of the lower chamber 6 into the mixer.

[0029] The slide plate 9 is movably connected to the slide 7. The slide plate 9 can move and move within the middle cavity 5, changing the passage of the middle cavity 5. This allows the flow rate of the middle cavity 5 to be changed, making it convenient and controllable to adjust the feed rate when conveying powder.

[0030] Tighten screw 8 to lock and limit the slide plate 9 after it has moved to the desired position;

[0031] The magnetic disk 11 is covered on the top of the middle cavity 5. At this time, the magnetic wall 10 and the magnetic disk 11 are magnetically connected to form a connection. At this time, the large upper hopper 12 is connected to the middle hopper 1 to increase the amount of powder to be fed, making it easier to feed a larger amount of magnesium carbon brick powder and providing better controllability during use.

[0032] The powder falls along the hopper cavity 13 and guide port 14, then flows through the middle cavity 5, and finally is discharged from the lower cavity 6, thus achieving the purpose of feeding the mixer.
