Description

Technical Field

[0001] This utility model relates to the field of magnesia-carbon brick technology, and in particular to a hopper for a corrosion-resistant magnesia-carbon brick conveyor. 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. When the powdered billet of magnesia-carbon bricks is being transported, a conveyor is used for conveying. The conveyor is equipped with a hopper for feeding the material.

[0003] Magnesium carbon brick conveyor hoppers have a simple structure. Generally, they have a single cavity inside to guide materials from top to bottom into the conveyor. However, when cleaning the inner wall of the hopper cavity, it is impossible to pass hot air into the hopper after cleaning, making it difficult to keep the hopper dry after cleaning. Utility Model Content

[0004] The purpose of this invention is to provide a hopper for a corrosion-resistant magnesium carbon brick conveyor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hopper for a corrosion-resistant magnesia-carbon brick conveyor includes a disc-shaped upper hopper with a vertically penetrating upper cavity for guiding materials. A lower hopper, wider at the top and narrower at the bottom, is fixedly connected to the lower end wall of the upper hopper. A lower cavity, also wider at the top and narrower at the bottom, is vertically penetrating the lower hopper and communicating with the upper cavity. Cylindrical guide tubes are fixedly connected to the two end walls at the bottom of the upper hopper. A guide channel extending into the upper hopper and communicating with the upper cavity is opened in the guide tube. A sealing plug at the bottom of the guide channel is threaded to the lower end of the guide tube.

[0007] Preferably, a disc-shaped bottom plate is fixed to the bottom end wall of the upper cavity of the upper bucket, and the bottom plate has circular openings distributed in a ring at the end wall.

[0008] Preferably, a disc-shaped top plate is provided above the bottom plate, and circular inlets are distributed in a ring at the end wall of the bottom plate.

[0009] Preferably, the inlet and the plate opening are aligned to connect the upper cavity and the lower cavity, while the inlet and the plate opening are misaligned to separate the upper cavity and the lower cavity.

[0010] Preferably, a cylindrical connecting column is fixedly connected to the center of the top wall of the top plate, and a top plate is fixedly connected to the top end wall of the connecting column.

[0011] Preferably, rectangular side seats are fixedly connected to the end walls on both sides of the lower bucket, and a screw is internally threaded to the side seat. A rectangular side seat is fixedly connected to the side wall of the screw, and a positioning hole for bolts to be inserted vertically through the center of the side seat for positioning and installing the side seat.

[0012] This utility model has at least the following beneficial effects:

[0013] During cleaning, water is flushed from the inner cavities of the upper and lower hoppers. Even after cleaning, water may still remain in the inner cavities. At this point, the sealing plug is rotated to open the guide channel, allowing some of the liquid accumulated on the end walls to drain down through the guide channel. A hot air pipe can also be connected to the bottom of the guide cylinder, allowing airflow to be injected into the upper cavity through the guide channel. This dries and protects the end walls of the upper and lower cavities, preventing moisture and corrosion. Attached Figure Description

[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 1-4This utility model provides a technical solution for a hopper used in a corrosion-resistant magnesia-carbon brick conveyor:

[0022] like Figure 1-4 As shown, a hopper for a corrosion-resistant magnesia-carbon brick conveyor includes a disc-shaped upper hopper 1, an upper cavity 2 for guiding materials vertically penetrating the upper hopper 1, a lower hopper 3 that is wider at the top and narrower at the bottom fixed to the lower end wall of the upper hopper 1, a lower cavity 4 for guiding materials vertically penetrating the lower hopper 3 and communicating with the upper cavity 2, and cylindrical guide tubes 5 fixed to the two end walls at the bottom of the upper hopper 1 respectively, a guide channel 6 extending into the upper hopper 1 and communicating with the upper cavity 2 is opened in the guide tube 5, and a sealing plug 7 at the bottom of the guide channel 6 is threaded to the lower end of the guide tube 5.

[0023] A disc-shaped bottom plate 8 is fixed to the bottom end wall of the upper cavity 2 of the upper bucket 1, and circular openings 9 are distributed in a ring at the end wall of the bottom plate 8.

[0024] A disc-shaped top plate 10 is provided above the bottom plate 8. Circular inlets 11 are distributed in a ring at the end wall of the bottom plate 8. The inlets 11 and the plate openings 9 are aligned and connect the upper cavity 2 and the lower cavity 4. The inlets 11 and the plate openings 9 are staggered and separate the upper cavity 2 and the lower cavity 4.

[0025] A cylindrical connecting column 12 is fixedly connected to the center of the top wall of the top plate 10, and a top plate 13 is fixedly connected to the top end wall of the connecting column 12.

[0026] Rectangular side seats 14 are fixedly connected to the two end walls of the lower bucket 3. A screw 15 is internally threaded to the side seat 14. A rectangular side seat 16 is fixedly connected to the side wall of the screw 15. A positioning hole 17 for bolts to be inserted vertically through the center of the side seat 16 is provided for positioning and installing the side seat 16.

[0027] Working principle:

[0028] In use, first rotate the side seat 16, drive the screw 15 and the side seat 14 to move the side seat 16 to the side and adjust the horizontal position of the side seat 16. After the two side seats 16 are adjusted to the horizontal position, insert bolts into the positioning holes 17 on the end wall of the side seat 16 to position and install the side seat 16 so that the side seat 16 is installed on the end wall of the magnesium carbon brick conveyor. Since the two side seats 16 are positioned and installed at the same time, the side seats 16 cannot move horizontally, thereby preventing the screw 15 from rotating, achieving the purpose of simple self-limiting of the screw 15.

[0029] Feeding: Magnesia-carbon brick blank powder is fed into the upper chamber 2 of the upper bucket 1, and discharged through the lower chamber 4 of the lower bucket 3. The powder is then discharged into the interior of the conveyor, completing the powder conveying process.

[0030] Simultaneously, the top plate 13 rotates, which drives the top plate 10 to rotate via the connecting column 12. Consequently, the inlet 11 on the end wall of the top plate 10 rotates accordingly, changing the orientation of the inlet 11 so that the inlet 11 and the plate opening 9 are either misaligned or aligned. When misaligned, the upper cavity 2 and the lower cavity 4 are separated by the bottom plate 8 and the top plate 10. Conversely, when aligned, the material flows from the upper cavity 2, the inlet 11, and the plate opening 9 into the lower cavity 4, which facilitates the control of the material conveying status, stopping or starting the conveying. Furthermore, when the plate opening 9 and the inlet 11 are staggered, it is possible to control the discharge of small amounts of material, thereby achieving the purpose of controlling the amount of material conveyed.

[0031] During cleaning, water is flushed from the inner cavities of the upper chamber 1 and lower chamber 3. After cleaning, water is still present in the inner cavities. At this time, the sealing plug 7 is rotated to open the guide channel 6, allowing some of the liquid accumulated on the end walls to drain down from the guide channel 6. The hot air pipe can be connected to the bottom of the guide cylinder 5, and the airflow is injected into the upper chamber 2 through the guide channel 6 to dry and protect the end walls of the upper chamber 2 and lower chamber 4, preventing moisture and corrosion on the end walls.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
