Description

A raw material proportioning and mixing device for the production of magnesia-carbon bricks Technical Field

[0001] This utility model relates to the field of mixing, and in particular to a raw material proportioning and mixing device for the production of magnesia-carbon bricks. Background Technology

[0002] Magnesia-carbon bricks are non-burning carbon composite refractory materials made from high-melting-point alkaline oxide magnesium oxide as raw material, with the addition of various non-oxide additives and carbonaceous binders. During production, the raw materials need to be mixed first to ensure that the various materials are evenly distributed so that subsequent sintering can be carried out to obtain the finished bricks. Water is also added to the raw materials during mixing to form a slurry-like raw material.

[0003] A search revealed Chinese patent application CN221868246U, which discloses a mud mixing device for magnesia-carbon brick production. The device includes a base, on which a mixing tank is fixedly connected to a stirring box. A pretreatment box is located at one end of the stirring box, and a crushing mechanism is mounted on the pretreatment box. The crushing mechanism includes a crushing motor welded to the pretreatment box. The output end of the crushing motor is connected to a drive gear via a drive shaft. A crushing wheel is located on the outer surface of the drive shaft. A driven shaft is movably connected to one end of the pretreatment box, and a driven gear is welded to one end of the driven shaft. A second crushing wheel is located on the outer surface of the driven shaft. The crushing motor drives the drive shaft to rotate, and through the meshing of the drive gear and driven gear, the driven shaft rotates in the opposite direction within the pretreatment box. This causes the first crushing wheel on the drive shaft and the second crushing wheel on the driven shaft to cooperate, thereby crushing the raw materials and improving the production quality of magnesia-carbon bricks.

[0004] Existing equipment typically mixes raw materials using a stirring rack, but the stickiness of the materials causes them to clump together, resulting in significant resistance on the stirring rack and affecting the mixing process. Summary of the Invention

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

[0006] A raw material proportioning and mixing device for magnesia-carbon brick production includes a base, two support plates, and a mixing tank. The two support plates are fixed to the top sides of the base. The mixing tank is rotatably connected to the two support plates via bearings. A feed port with a threaded groove is provided on one side of the top of the mixing tank, and a threaded plug is threaded into the threaded groove. A discharge port with a sealing plug is provided at the bottom of the mixing tank. A stirring port is opened on the top of the mixing tank, and a cover plate is connected to one side of the stirring port. A stirring frame is provided between the cover plate and the interior of the mixing tank. A transmission mechanism is provided between the mixing tank and the stirring frame. The transmission mechanism includes a drive motor, a rotating shaft, a gear, a gear ring, a first pulley, a second pulley, and a belt. The drive motor is fixed to the side of the support plate. The rotating shaft is rotatably connected to the support plate. The gear is fixedly sleeved on the rotating shaft. The gear ring is fixedly sleeved on the outer wall of the mixing tank and meshes with the gear. The first pulley is fixedly sleeved on the rotating shaft, and the second pulley is fixedly sleeved on the stirring frame. The belt drive connects the first pulley and the second pulley.

[0007] Preferably, the mixing tank is set in an inclined state.

[0008] Preferably, the transmission mechanism is configured such that the rotation direction of the mixing tank is opposite to the rotation direction of the stirring rack.

[0009] Preferably, the stirring frame includes a rotating rod, multiple stirring blades, and multiple auger blades. The rotating rod and the cover plate are rotatably connected by bearings, and the multiple stirring blades and multiple auger blades are all fixed on the outer circumference of the rotating rod.

[0010] Preferably, the stirring blades and auger blades are alternately distributed along the axis of the rotating rod.

[0011] Preferably, the rotation of the mixing tank is achieved through the meshing transmission of the gear and the gear ring, and the rotation of the stirring frame is achieved through the transmission of the first pulley, the second pulley and the belt.

[0012] Preferably, the feed port is located on one side of the top of the mixing tank, and its axis is adapted to the tilt direction of the mixing tank.

[0013] Preferably, the auger blades are configured to convey raw materials deposited at the bottom of the mixing tank upwards when rotating.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model, through the configuration of a mixing tank, transmission mechanism, and stirring frame, allows for the production of magnesia-carbon bricks. The proportioned raw materials are fed into the mixing tank via the feed port. After filling, the feed port is sealed with a threaded plug. The transmission motor is then activated, driving the gears to rotate. The meshing between the gears and the gear ring causes the gear ring to rotate the mixing tank. Simultaneously, the first pulley rotates synchronously with the rotating shaft. The cooperation between the first pulley, the second pulley, and the belt causes the second pulley to rotate the stirring frame inside the mixing tank. This stirring frame then stirs the raw materials inside the mixing tank. Furthermore, the mixing tank rotates in the opposite direction to the stirring frame, accelerating the mixing process and improving the uniformity of the raw material mixture. This enhances the stirring effect inside the mixing tank and prevents the raw materials from sticking together, which would increase the resistance on the stirring frame and affect the mixing effect. Additionally, because the mixing tank is tilted, raw materials adhering to the inner wall of the mixing tank slide to the bottom, further improving the mixing effect.

[0016] 2. This utility model, through the arrangement of stirring blades and auger blades, allows the raw materials deposited at the bottom to move upwards under the action of the auger blades during the mixing process by the stirring frame. Subsequently, the raw materials are stirred again by the stirring blades. Since the stirring blades and auger blades are alternately distributed, the cooperation between the stirring blades and auger blades can effectively and thoroughly mix the raw materials inside the mixing tank, avoiding the accumulation of raw materials at the bottom of the mixing tank, which would result in poor mixing effect.

Detailed Implementation

[0023] Example 1, referring to Figures 1-4, a raw material proportioning and mixing device for magnesia-carbon brick production includes a base 1, two support plates 3, and a mixing tank 2. The two support plates 3 are fixed to the top of the base 1 on both sides by bolts. The mixing tank 2 and the two support plates 3 are rotatably connected by bearings. A feed port 5 is provided on one side of the top of the mixing tank 2. A threaded groove is opened on the inner wall of the feed port 5. The threaded groove is threadedly connected to a threaded plug 6. A discharge port is provided at the bottom of the mixing tank 2. A sealing plug 4 is provided on the inner wall of the discharge port. A stirring port 8 is opened at the top of the mixing tank 2. A cover plate 9 is bolted to one side of the stirring port 8. A stirring frame 10 is provided between the cover plate 9 and the interior of the mixing tank 2. A transmission mechanism 7 is provided between the mixing tank 2 and the stirring frame 10.

[0024] The transmission mechanism 7 includes a drive motor 11, a rotating shaft 12, a gear 13, a gear ring 16, a first pulley 14, a second pulley 17, and a belt 15. The drive motor 11 is fixed to one side of one of the support plates 3 by bolts. The rotating shaft 12 is rotatably connected to the support plate 3 by bearings. The gear 13 is fixedly sleeved on the rotating shaft 12. The gear ring 16 is fixedly sleeved on the outer wall of the mixing tank 2 and meshes with the gear 13 and the gear ring 16. The first pulley 14 is fixedly sleeved on the rotating shaft 12. The second pulley 17 is fixedly sleeved on the stirring frame 10. The belt 15 is rotatably connected to the first pulley 14 and the second pulley 17.

[0025] During the production of magnesia-carbon bricks, the proportioned raw materials are fed into the mixing tank 2 through the feed port 5. After filling, the feed port 5 is sealed with a threaded plug 6. At this time, the drive motor 11 is started, which drives the gear 13 to rotate. The meshing between the gear 13 and the gear ring 16 causes the gear ring 16 to drive the mixing tank 2 to rotate. Simultaneously, the first pulley 14 rotates synchronously with the rotation of the shaft 12. Through the cooperation between the first pulley 14, the second pulley 17, and the belt 15, the second pulley 17 drives the stirring blade 18 to rotate inside the mixing tank 2. Thus, the stirring blade 18 stirs the raw materials inside the mixing tank 2. In addition, the rotation direction of the mixing tank 2 is opposite to the rotation direction of the stirring frame 10, which can accelerate the mixing process and improve the uniformity of the raw material mixing, improve the stirring effect of the raw materials inside the mixing tank 2, and prevent the raw materials from sticking together due to their viscosity, which would increase the resistance of the stirring frame 10 and affect the mixing effect of the raw materials.

[0026] In this invention, in order to facilitate the processing of raw materials adhering to the inner wall of the mixing tank 2, the mixing tank 2 is tilted, and the raw materials adhering to the inner wall of the mixing tank 2 will slide to the bottom of the mixing tank 2, thereby improving the mixing effect of the raw materials.

[0027] Example 2, referring to Figures 1-5, describes a raw material proportioning and mixing device for magnesia-carbon brick production. Compared to Example 1, the mixing frame 10 includes a rotating rod 20, multiple stirring blades 18, and multiple auger blades 19. The rotating rod 20 and the cover plate 9 are rotatably connected by bearings. The multiple stirring blades 18 and multiple auger blades 19 are fixed on the outer circumference of the rotating rod 20. The stirring blades 18 and auger blades 19 are alternately distributed. When the raw materials are stirred and mixed by the mixing frame 10, the raw materials deposited at the bottom of the raw materials will move upward under the action of the auger blades 19, and then be stirred by the stirring blades 18. Since the stirring blades 18 and auger blades 19 are alternately distributed, the cooperation between the stirring blades 18 and auger blades 19 can effectively and fully stir and mix the raw materials inside the mixing tank 2, avoiding the accumulation of raw materials at the bottom of the mixing tank 2, which would result in poor stirring effect.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
