Abstract
Description
Technical Field
[0001] This invention relates to the field of magnesia-carbon brick mixing technology, specifically to a raw material mixer for magnesia-carbon brick experiments. Background Technology
[0002] Magnesia-carbon bricks are non-burning composite refractory materials 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 and bonded with carbonaceous binders. When mixing the raw materials for magnesia-carbon bricks, a stirrer is used to mix them.
[0003] The stirrer has a simple structure, generally consisting of a barrel, stirring blades, and a motor. It is used for simple mixing of raw materials. After the stirrer is used, there is raw material left on the inner wall. When it is used again, the newly added raw material is easy to mix with the residual raw material, causing contamination. This is not conducive to the use of raw materials in subsequent experiments, and consequently, the experimental structure is not accurate enough. Summary of the Invention
[0004] The purpose of this invention is to provide a raw material stirrer for magnesia-carbon brick experiments, in order to solve the problems mentioned in the background art. The existing stirrers have simple structures, generally consisting of a barrel, stirring blades, and a motor. They simply stir and mix the raw materials. After the stirrer is used, there are raw materials on the inner wall. When the stirrer is used again, the newly added raw materials are easy to mix with the residual raw materials, causing contamination. This is not conducive to the use of raw materials in subsequent experiments, and consequently, the experimental structure is not accurate enough during the experiment.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a raw material stirrer for magnesia-carbon brick experiments, comprising a cylindrical stirring tank, a chamber inside the stirring tank, a disc-shaped top cover being snapped onto the top of the stirring tank, a motor being fixedly connected to the top wall of the center of the top cover, a stirring shaft extending into the chamber being drivenly connected to the end of the motor, a stirring blade for stirring the raw material being fixedly connected to the end wall of the stirring shaft, and a base plate for supporting the stirring tank being detachably rotatably connected to the bottom of the stirring tank.
[0006] Preferably, a central seat is fixedly connected to the center end wall of the top of the base plate, and a cylindrical top column is fixedly connected to the center end wall of the top of the central seat.
[0007] Preferably, a base is fixedly connected to the center end wall of the bottom of the mixing tank, and a column opening is provided at the center end wall of the base for insertion and rotatable connection with the top column.
[0008] Preferably, the mixing tank has a discharge port on both sides of the bottom end wall that communicates with the tank cavity, and a screw-on cover is provided on the end wall of the discharge port. The screw-on cover has a cover cavity that is threadedly connected to the discharge port.
[0009] Preferably, the mixing tank has side cavities at both ends of its left and right side walls, and a side joint is fixedly connected to the end wall of the mixing tank near the side cavity.
[0010] Preferably, the side connector has a connection port that penetrates the upper wall of the side connector, and the adjacent end walls of the side connector and the mixing tank have inlet ports that communicate with both the side cavity and the connection port.
[0011] Preferably, a heating tube is inserted into the connector of the side connector, a top opening is provided on the top end wall of the top cover, and a top plug is internally threaded onto the top cover.
[0012] Preferably, a bottom groove is provided on both sides of the bottom plate, a bottom groove buckle is snapped into the bottom groove, a storage seat is fixed to the top end wall of the bottom groove buckle, a storage cavity is provided on the upper end wall of the storage seat, and partition plates are fixedly distributed at equal intervals in the storage cavity.
[0013] Preferably, a threaded opening is provided at the bottom end wall of the storage base, and a threaded plug is threadedly connected to the threaded opening. A connecting opening is provided at the end wall of the base plate near the bottom groove and the center seat, and a connecting plug is threadedly connected to the center seat.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, the mixing tank and the top cover are snapped together. The stirring shaft and stirring blades at the top cover extend into the tank cavity. The top plug at the top opening of the top cover rotates, and the top plug is removed and installed to open and close the top opening, making it convenient to add raw materials at the top opening and put the raw materials into the tank cavity. Then the top plug rotates to close the top opening, the motor runs, drives the stirring shaft to run, and the stirring blades to rotate, mixing and stirring the raw materials in the tank cavity. 2. During the mixing process, a heating tube is inserted into the inlet. The heating tube heats up, and the inlet, the inlet, and the side cavity are heated in sequence. The side cavity is heated, and then the whole barrel cavity is heated. At this time, the raw materials in the barrel cavity or the end wall of the barrel cavity are dried and protected, and moisture is removed. 3. After mixing, rotate the screw cap to disassemble from the discharge port, open and close the discharge port. After opening the discharge port, the mixed raw materials in the barrel cavity will be discharged from the discharge port. The two discharge ports can discharge raw materials separately. 4. The bottom groove opening of the base plate is snapped with a bottom groove buckle for assembling the storage base, which facilitates the assembly and disassembly of the storage base. When receiving materials, the storage cavity of the storage base receives the raw materials. After the dividing plate is lowered, the received raw materials are divided into three equal parts to facilitate the sampling of raw materials in equal parts. When conducting tests, more samples are available. When removing materials, the storage base is raised, and the threaded plug at the threaded opening is rotated to open and close the threaded opening to facilitate the discharge of raw materials. 5. Rotate the connecting plug at the connection port to change the height of the connecting plug. After the connecting plug moves up, the upper wall of the connecting plug contacts the bottom wall of the fixed seat. At this time, the center seat and the fixed seat are limited together, and the fixed seat and the mixing tank cannot rotate, so that the mixing tank can be used after being positioned. Conversely, the mixing tank can rotate according to the top column and column opening. When the mixing tank rotates, the position of the lower discharge port of the magnesia-carbon brick raw material changes, so as to facilitate the convenient handling and storage of materials. 6. Meanwhile, the top column and column opening are connected by a plug-in mechanism, which facilitates the disassembly and assembly of the mixing tank and the bottom plate. The mixing tank and the top cover are snap-fitted together, which also facilitates the disassembly and assembly of the mixing tank and the top cover, so that they can be disassembled separately for individual cleaning and removal of raw material residue.

A connecting plug 10 is threaded into the center seat 11.
[0021] In summary, the raw material mixer used in this magnesia-carbon brick experiment should be used as follows: The mixing tank 15 and the top cover 20 are snapped together. The stirring shaft 24 and stirring blade 25 at the top cover 20 extend into the tank cavity 16. The top plug 22 at the top opening 21 of the top cover 20 rotates, and the top plug 22 is removed and installed to open and close the top opening 21, making it convenient to add raw materials at the top opening 21, so that the raw materials are put into the tank cavity 16. Then the top plug 22 rotates to close the top opening 21, the motor 23 runs, drives the stirring shaft 24 to run, and the stirring blade 25 rotates to mix and stir the raw materials in the tank cavity 16. During the stirring process, a heating tube 30 is inserted into the inlet 28. The heating tube 30 runs and heats up, and the inlet 28, the inlet 29, and the side cavity 26 are heated in sequence. The side cavity 26 is heated, and then the barrel cavity 16 is heated. At this time, the raw materials in the barrel cavity 16 or the end wall of the barrel cavity 16 are dried and protected, and moisture is removed. After mixing, rotate the screw cap 18 and disassemble it from the discharge port 17. Open and close the discharge port 17. After opening the discharge port 17, the mixed raw materials in the barrel cavity 16 are discharged from the discharge port 17. The two discharge ports 17 can discharge raw materials separately. The bottom groove opening 2 of the base plate 1 is snapped with the bottom groove buckle 3 for assembling the storage base 4, which facilitates the assembly and disassembly of the storage base 4. When receiving materials, the storage cavity 5 of the storage base 4 receives the raw materials, and the dividing plate 6 divides the received raw materials into three equal parts, so that the raw materials can be sampled in equal parts and more samples can be obtained when conducting test processing. When removing materials, the storage base 4 is raised, and the thread plug 8 at the threaded opening 7 is rotated to open and close the threaded opening 7, so that the raw materials can be discharged. The connecting plug 10 at the connection port 9 rotates, changing the height of the connecting plug 10.

At this time, the center seat 11 and the fixed seat 13 are limited together, and the fixed seat 13 and the mixing tank 15 cannot rotate, so that the mixing tank 15 can be used after being positioned. Conversely, the mixing tank 15 can rotate according to the top column 12 and the column opening 14. When the mixing tank 15 rotates, the position of the lower discharge port 17 of the magnesia-carbon brick raw material changes, so as to facilitate the collection and storage of materials. Meanwhile, the top column 12 and column opening 14 are connected by a plug-in movable connection, which facilitates the disassembly and assembly of the mixing tank 15 and the bottom plate 1. The mixing tank 15 and the top cover 20 are snap-fitted together, which facilitates the disassembly and assembly of the mixing tank 15 and the top cover 20, so that they can be disassembled separately for individual cleaning and removal of raw material residue.
