Description

Technical Field

[0001] The invention relates to the technical field of raw material mixing, and in particular to a high-efficiency mixing device and method for refractory materials. Background Art

[0002] The raw materials of refractory materials are roughly divided into aggregates with larger mesh size and small aggregates with smaller mesh size. The number of small aggregates is small and the mesh size is small. Changing the addition amount and ratio of small aggregates can greatly improve the fireproof and high temperature resistance of refractory materials.

[0003] Traditional mixing equipment adds aggregates and small materials into a mixing container from the top or one side, and continuously stirs and dry mixes them to ensure the mixing degree of the aggregates and small materials. After the dry mixing is completed, water is added for wet mixing to fully mix the aggregates, small materials and water. Finally, the stirred materials are transported to a mold for processing and molding to obtain finished refractory panels or refractory bricks.

[0004] By premixing aggregates and small materials, the degree of mixing between the two can be improved, and the quality of the finished refractory materials can be improved; however, the premixing method requires that the aggregates and small materials be mixed in two devices in succession, which increases the equipment investment and the mixing steps, increases the time for mixing the aggregates and small materials as a whole, and reduces the efficiency of the mixed preparation of the refractory materials; and for the premixing of aggregates and small materials with a large difference in mesh size, the premixing time is further increased, and the traditional flipping premixing method has a poor mixing degree and a long premixing time.

[0035] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0036] Refractory materials are mostly made of a mixture of high-temperature resistant materials such as metal oxides, carbon materials, and silicides. They can withstand sufficiently high temperatures to achieve the effects of fire prevention and temperature resistance.

[0037] The raw materials of refractory materials are roughly divided into aggregates with larger mesh size and small aggregates with smaller mesh size. The number of small aggregates is small and the mesh size is small. Changing the addition amount and ratio of small aggregates can greatly improve the fireproof and high temperature resistance of refractory materials.

[0038] Traditional mixing equipment adds aggregates and small materials into a mixing container from the top or one side, and continuously stirs and dry mixes them to ensure the mixing degree of the aggregates and small materials. After the dry mixing is completed, water is added for wet mixing to fully mix the aggregates, small materials and water. Finally, the stirred materials are transported to a mold for processing and molding to obtain finished refractory panels or refractory bricks.

[0039] By premixing aggregates and small materials, the degree of mixing between the two can be improved, and the quality of the finished refractory materials can be improved; however, the premixing method requires that the aggregates and small materials be mixed in two devices in succession, which increases the equipment investment and the mixing steps, increases the time for mixing the aggregates and small materials as a whole, and reduces the efficiency of the mixed preparation of the refractory materials; and for the premixing of aggregates and small materials with a large difference in mesh size, the premixing time is further increased, and the traditional flipping premixing method has a poor mixing degree and a long premixing time.

[0040] In order to solve the above problems, refer to the attached Figure 1 -Attached Fig.10 A high-efficiency mixing equipment for refractory materials has changed the traditional way of mixing aggregates and small materials. The premixing, dry mixing and wet mixing of refractory raw materials can be completed by one device, thereby improving the mixing degree of refractory materials, shortening the mixing time of refractory raw materials as a whole, and reducing the mixing cost. Specifically, it includes a carrying platform, a mixing tank body 300 is arranged at the upper end of the carrying platform, a material feeding device 400 is arranged at the upper end of the mixing tank body 300, a mixing shaft 320 is rotatably connected inside the mixing tank body 300, and a plurality of mixing components 340 extending toward the inner wall direction of the mixing tank body 300 are circumferentially arranged on the surface of the mixing shaft 320; the mixing component 340 can rotate continuously in a predetermined direction, and can disperse and fully mix aggregates and small materials in the premixing stage; can fully mix aggregates and small materials again in the dry mixing stage, and can fully mix aggregates, small materials and liquid in the wet mixing stage, and then the fully mixed materials are placed in a prefabricated mold for processing and molding to prepare refractory materials.

[0041] Here, the material delivery device 400 can be used to evenly deliver aggregates and small materials at the top, and premixing of the aggregates and small materials is achieved in the process of passing through the mixing component 340. At the same time, the material delivery device 400 can evenly deliver aggregates and small materials according to a predetermined ratio, which greatly improves the efficiency of mixing aggregates and small materials.

[0042] Specifically, the material delivery device 400 includes a first delivery component 440 for delivering aggregates and a second delivery component 430 for delivering small materials. The first delivery component 440 and the second delivery component 430 are located above the top mixing component 340. The second delivery component 430, the first delivery component 440 and the mixing component 340 are controlled to rotate around the mixing shaft 320 to complete the mixing of aggregates and small materials.

[0043] Here, the second delivery component 430 and the first delivery component 440 both extend toward the inner wall of the mixing tank body 300. The second delivery component 430 and the first delivery component 440 are both in a long strip state, which can evenly deliver the aggregates and small materials within a certain length range to achieve efficient delivery and mixing of the aggregates and small materials. The aggregates and small materials are delivered downward under the action of gravity like a waterfall to achieve efficient mixing.

[0044] It should be noted here that, in the process of aggregates and small materials being delivered by the first delivery component 440 and the second delivery component 430, they can contact with the mixing component 340, and in the process of the mixing component 340 rotating, the falling aggregates and small materials can be fully dispersed, thereby further improving the mixing effect of the aggregates and small materials; and the delivery length distance of the first delivery component 440 and the second delivery component 430 here is less than the mixing radius of the second delivery component 430, so as to ensure that the aggregates and small materials are fully mixed in the process of falling; at the same time, the delivery positions of the aggregates and small materials here are close to each other, and in the process of controlling the continuous rotation of the second delivery component 430 and the first delivery component 440, the aggregates and small materials can be relatively evenly distributed in the mixing tank body 300, thereby achieving efficient delivery and dispersion, and reducing the subsequent dry mixing time.

[0045] It should also be noted here that the second delivery component 430 and the first delivery component 440 are both fixed on the surface of the delivery shaft 450, and the delivery shaft 450 is separately connected to a first belt drive component 460 for controlling the directional rotation of the delivery shaft 450. The delivery shaft 450 is rotationally connected to the mixing shaft 320, and can control the delivery shaft 450 and the mixing shaft 320 to rotate at different speeds or in different directions to meet the needs of premixing during the delivery of aggregates and small materials.

[0046] In summary, compared with the traditional centralized placement of aggregates and small materials or distributed mixing solutions, the above-mentioned structural design can complete the premixing, dry mixing and wet mixing of aggregates and small materials in the mixing tank 300 in sequence, which greatly improves the dispersion degree of aggregates and small materials and improves the mixing effect; aggregates and small materials can be automatically placed, which simplifies the steps of mixing refractory raw materials and improves the mixing efficiency.

[0047] The material delivery device 400 also includes a first delivery part 420 that rotates synchronously with the first delivery component 440 and the second delivery component 430. The upper end of the first delivery part 420 is rotatably connected to a relatively fixed second delivery part 410, wherein aggregates and small materials pass through the second delivery part 410 and the first delivery part 420 in turn and are finally delivered from the first delivery component 440 and the second delivery component 430 respectively. The position of the second delivery part 410 is relatively fixed, and the position of the first delivery part 420 rotates relatively. The first delivery part 420 can rotate synchronously with the first delivery component 440 and the second delivery component 430 to achieve synchronous delivery of aggregates and small materials. The position of the second delivery part 410 is relatively fixed and can be connected to the external material conveying equipment to achieve stable delivery of aggregates and small materials.

[0048] The first delivery part 420 includes a first delivery ring 421 and a second delivery ring 422 which are coaxially arranged. The radius of the first delivery ring 421 is larger than that of the second delivery ring 422. A first delivery chamber which is connected to the first delivery component 440 is formed inside the first delivery ring 421, and a second delivery chamber which is connected to the second delivery component 430 is formed between the inside of the second delivery ring 422 and the outside of the first delivery ring 421. Small materials pass through the second delivery chamber and are finally delivered from the second delivery component 430, and aggregates pass through the first delivery chamber and are finally delivered from the first delivery component 440. Here, the second delivery part 410 and the first delivery part 420 are both configured to be reversed to ensure that the horizontal projection areas of the first delivery chamber and the second delivery chamber remain relatively unchanged during the relative rotation of the second delivery part 410 and the first delivery part 420, thereby ensuring the normal delivery of aggregates and small materials.

[0049] It should be noted here that the sizes of the first delivery chamber and the second delivery chamber are determined comprehensively according to the ratio of aggregate and small materials delivered. Generally speaking, the amount of aggregate delivered is much larger than the amount of small materials delivered. The cross-sectional dimensions of the first delivery chamber and the second delivery chamber are set to the corresponding sizes to ensure that aggregate and small materials can be delivered in a predetermined ratio.

[0050] The second delivery part 410 includes a third delivery ring 411 adapted to the first delivery ring 421, and also includes a fourth delivery ring 412 adapted to the second delivery ring 422. By setting the third delivery ring 411 and the fourth delivery ring 412, they can be adapted to the first delivery ring 421 and the second delivery ring 422 respectively. During the rotation of the first delivery part 420, the aggregates and small materials can smoothly pass through the second delivery part 410 and the first delivery part 420 in turn under the action of gravity, and finally be discharged from the second delivery component 430 and the first delivery component 440 respectively, thereby ensuring the stability of the delivery of aggregates and small materials.

[0051] Please refer to the attached Fig.10 Specifically, the mixing assembly 340 includes a mounting base 342 and a stirring rod 343 fixed to the outside of the mounting base 342. The cross-section of the stirring rod 343 is a triangle, and the triangle here is preferably an isosceles triangle; the mounting base 342 is rotatably connected to the mixing shaft 320 through a mounting collar 341, and the mounting base 342 and the mounting collar 341 are sealed and rotatably connected. The interior of the mixing shaft 320 is hollow and is provided with a control assembly for controlling the rotation of the stirring rod 343. The interior of the mixing shaft 320 is hollow to form a hollow portion 321. The control assembly is located in the hollow portion 321, and can adjust and control the positions of multiple stirring rods 343, so that the stirring rod 343 at the end can rotate according to a predetermined posture, which can further improve the mixing efficiency of aggregates and small materials in the premixing and dry mixing stages to ensure that the two are fully mixed.

[0052] It should be noted here that, in the pre-mixing and dry mixing stage, the mid-vertical line of the stirring rod 343 is controlled to be inclined at a predetermined angle, so that the aggregates and small materials can be mixed efficiently.

[0053] Specifically, the control component includes a first connecting member 333, a second connecting member 334 and a control unit 330. The edges of two adjacent mounting bases 342 are connected by the second connecting member 334, and the edge of the mounting base 342 located at the bottom is connected to the control unit 330 by the first connecting member 333. During the control process, the mounting base 342 located at the bottom can be controlled to rotate by pulling the first connecting member 333, thereby adjusting the rotation state of the outer stirring rod 343. At the same time, two adjacent mounting bases 342 are connected by the second connecting member 334, and multiple mounting bases 342 can rotate synchronously. The deflection angles of multiple stirring rods 343 can be synchronously controlled by the second connecting member 334 and the first connecting member 333.

[0054] As a first implementation of the first connecting member 333 and the second connecting member 334 , both can be made of rigid materials. A telescopic structure is provided at the bottom of the first connecting member 333 to achieve synchronous control of the first connecting member 333 and the second connecting member 334 , and to achieve synchronous adjustment of multiple stirring rods 343 .

[0055] As a second embodiment of the first connecting member 333 and the second connecting member 334, both can be selected to be flexible materials in a targeted manner, and a torsion elastic component, preferably a torsion spring, is provided between the mounting base 342 and the mounting ring 341, and is installed in the hollow part 321. The first connecting member 333 here is a connecting rope, and the position of the bottom stirring rod 343 can be adjusted by pulling the connecting rope to achieve efficient adjustment; at the same time, the multiple stirring rods 343 at the top can be adjusted and controlled under the connection of the second connecting member 334 to achieve synchronous adjustment.

[0056] Furthermore, the control unit 330 includes a control tube 331 and a control column 332. The control tube 331 rotates synchronously with the mixing shaft 320. The upper end of the control column 332 is fixedly connected to the connecting rope, and the control column 332 is slidably connected to the control tube 331. The control tube 331 and the mixing shaft 320 rotate synchronously here, ensuring that the control column 332 can rotate synchronously with the first connecting member 333 to achieve synchronous adjustment and control. Manual or electric adjustment of the linear movement of the control column 332 can adjust the position of the control column 332 and the first connecting member 333 at the upper end of the control column 332, thereby achieving synchronous adjustment of the deflection angles of multiple outer stirring rods 343.

[0057] Please refer to the attached Fig. 9 Here, the first delivery assembly 440 includes a first delivery pipe 442 and a first communicating vessel 441, and the second delivery assembly 430 includes a second delivery pipe 431 and a second communicating vessel 432. The opening directions of the first delivery pipe 442 and the second delivery pipe 431 are opposite to their rotation directions. Aggregates and small materials can be continuously discharged from the opening of the side wall. Vibrating rods can be installed on the outside of the second delivery assembly 430 and the first delivery assembly 440 to vibrate and discharge the aggregates and small materials. Aggregates and small materials can be evenly discharged from multiple positions under the action of vibration; the opening here is located on one side of the side wall, and the inner side has a certain depth to ensure that the aggregates and small materials can move evenly toward the outside; and the opening directions of the two are controlled to be opposite to the rotation direction, and the height of the first delivery assembly 440 here is greater than that of the second delivery assembly 430. The flowing curtain wall formed by the aggregates delivered by the first delivery assembly 440 can block the small materials inside, and carry the small materials toward the bottom of the mixing tank body 300, which accelerates the sedimentation and mixing process of the aggregates and small materials, and further ensures that the two are efficiently mixed.

[0058] The supporting platform includes a first supporting part 100 which is relatively fixed and a second supporting part 200 which is rotatably connected to the first supporting part 100. The mixing tank body 300 is fixed to the second supporting part 200. An opening and closing control device 500 is arranged between the first supporting part 100 and the second supporting part 200. The opening and closing control device 500 here can be selected as a hydraulic telescopic structure or a screw position control structure. The purpose is to control the second supporting part 200 to drive the mixing tank body 300 to deflect a predetermined angle.

[0059] Under the condition of premixing, the mixing tank body 300 is controlled to be in a horizontal state, and the aggregates and small materials are downwardly acted upon by gravity to be perpendicular to the bottom of the mixing tank body 300, so that the aggregates and small materials can be put in and premixed relatively evenly.

[0060] Under the conditions of dry mixing and wet mixing, the mixing tank body 300 is controlled to tilt at a predetermined angle, and the aggregates and small materials are concentrated on one side. During the continuous rotation of the mixing assembly 340, the aggregates and small materials can be mixed more efficiently and centrally, further improving the mixing efficiency of the two and reducing the overall consumption.

[0061] The present invention is further described below in conjunction with the method.

[0062] A method for efficiently mixing refractory materials, using the above-mentioned efficient refractory material mixing device, comprises the following steps:

[0063] S1. Control the second delivery component 430, the first delivery component 440 and the mixing component 340 to rotate around the mixing shaft 320; the second delivery component 430, the first delivery component 440 and the mixing component 340 can rotate in the same direction at different speeds. Preferably, the second delivery component 430, the first delivery component 440 and the mixing component 340 rotate in opposite directions to further improve the mixing effect of aggregates and small materials.

[0064] S2. Control the first delivery component 440 to deliver aggregates, and control the second delivery component 430 to deliver small materials. The aggregates and small materials pass through the mixing component 340 under the action of gravity to complete a mixing process. At this time, the aggregates and small materials are premixed in the mixing tank body 300. In this process, the aggregates and small materials are efficiently mixed in the mixing tank body 300 according to a predetermined ratio, ensuring that the two are fully dispersed and mixed.

[0065] S3, continue to rotate the mixing assembly 340 to complete the secondary mixing of the aggregate and the small material; at this time, the aggregate and the small material are put in, and the two are dry mixed at the bottom of the mixing tank 300.

[0066] S4. Liquid medium is added into the mixing tank 300. The liquid medium, aggregate and small material are mixed three times. At this time, the addition of liquid can finally mix the aggregate and small material, that is, wet mixing. After a predetermined wet mixing time, the mixed fluid medium is discharged, and different styles of refractory materials are prepared after solidification treatment.

[0067] This solution changes the traditional way of mixing aggregates and small materials. Through one device, the premixing, dry mixing and wet mixing of refractory raw materials can be completed, which improves the mixing degree of refractory raw materials, shortens the mixing time of refractory raw materials as a whole, and reduces the mixing cost.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
