Description

Technical Field

[0001] The invention relates to the technical field of refractory brick production, in particular to a raw material quantitative mixing device for refractory brick processing. Background Art

[0002] Refractory bricks are refractory materials made by burning refractory clay or other refractory raw materials. They are mainly used for building smelting furnaces and can withstand high temperatures of 1580℃-1770℃. They are also called fire bricks. They are refractory materials with certain shapes and sizes. According to the preparation process, they can be divided into fired bricks, unfired bricks, fused bricks (fused cast bricks), and refractory insulation bricks. According to their shapes and sizes, they can be divided into standard bricks, ordinary bricks, special bricks, etc. They can be used as high-temperature building materials and structural materials for building kilns and various thermal equipment, and can withstand various physical and chemical changes and mechanical actions at high temperatures. Refractory masonry is calcined with a variety of different raw materials to form refractory bricks.

[0030] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] like Figure 1-10The raw material quantitative mixing device for refractory brick processing shown in the figure comprises a mixing tank 1, and a mixing mechanism 2 arranged in the mixing tank 1 for stirring the refractory brick raw material. The mixing mechanism 2 is mainly composed of a motor and a stirring frame and other structures. It is a mature technology in the prior art and will not be described in detail here. A discharge frame 3 is fixedly connected to the top of the mixing tank 1, and a quantitative cylinder 4 is fixedly connected to the top of the discharge frame 3. A discharge mechanism 5 for quantitatively discharging the raw material in the quantitative cylinder 4 is arranged in the discharge frame 3. The discharge mechanism 5 is mainly composed of a driving mechanism and a blocking structure, which can automatically open the blockage of the arc-shaped discharge port 7 and Controlling the amount of discharge in each area, so as to achieve quantitative discharge of refractory brick raw materials, is a mature technology in the prior art, and will not be described in detail here. An upper cylinder 8 is fixedly connected to the center position of the dosing cylinder 4, and four partitions 6 are fixedly connected to the inner side of the dosing cylinder 4 and the upper cylinder 8 at equal distances. The dosing cylinder 4 is separated into four storage spaces by the four partitions 6, and four types of refractory brick raw materials can be stored. An arc-shaped discharge port 7 is opened at the bottom end of the dosing cylinder 4 and located between the four partitions 6. The side walls of the four partitions 6 are provided with adjustment plates 9. Four lower cylinders 10 are rotatably connected to the inner side of the upper cylinder 8;

[0033] The outer wall of the upper cylinder 8 and the positions corresponding to the four lower cylinders 10 are all provided with arc grooves 11, and the four arc grooves 11 are equidistantly distributed on the outer wall of the upper cylinder 8 in a stepped manner. The four arc grooves 11 are distributed in a stepped manner on multiple upper cylinders 8, so that the adjustment position of each adjustment plate 9 can be isolated to avoid being restricted during the adjustment process. The side walls of the adjustment plate 9 and the positions corresponding to the arc grooves 11 are fixedly connected with sliding plates 12, and the side walls of the sliding plates 12 are respectively fixedly connected to the outer walls of the corresponding lower cylinders 10, and the inner sides of the lower cylinders 10 and the positions corresponding to the arc grooves 11 are provided with inclined grooves 13. A rectangular rod 14 is fixedly connected to the bottom end of the quantitative cylinder 4 and located inside the upper cylinder 8, and a round rod 15 is provided on the top of the inner side of the inclined groove 13. The side walls of the round rod 15 are fixedly connected with a moving block 16, and a threaded rod 17 is threadedly connected to the top of the upper cylinder 8 and the position corresponding to the moving block 16, and the bottom of the threaded rod 17 is rotatably connected to the top of the moving block 16;

[0034] When quantitatively mixing the refractory brick raw materials, firstly, the refractory brick raw materials are placed between the partitions 6 in the quantitative cylinder 4, and then during mixing, the discharge mechanism 5 is controlled to start to release the blockage at the arc-shaped discharge port 7, and the raw materials in the quantitative cylinder 4 are quantitatively discharged into the mixing tank 1. After the quantitative discharge is completed, the discharge mechanism 5 is closed and the mixing mechanism 2 is controlled to start, and the raw materials in the mixing tank 1 are mixed. After the mixing is completed, the discharge port at the bottom of the mixing tank 1 is opened to discharge the mixed raw materials;

[0035] If the storage space of the metering cylinder 4 on the mixing tank 1 needs to be adjusted according to the demand for increasing the amount of raw materials for refractory brick production, first, the raw materials in the space to be adjusted are discharged, and then the corresponding rotating block 20 is rotated to drive the threaded rod 17 to rotate. Since the threaded rod 17 is threadedly connected to the upper cylinder 8, the thread of the threaded rod 17 will rotate downward, thereby pushing the moving block 16 to drive the guide block 19 to slide on the guide groove 18, and at the same time drive the round rod 15 to slide downward. Since the round rod 15 slides in the inclined groove 13, and the round rod 15 is restricted by the sliding of the guide block 19 in the guide groove 18, it can only slide up and down, so it will squeeze the inclined groove 13 to drive the lower cylinder 10 to rotate on the inner side of the upper cylinder 8, and then drive the sliding plate 12 to slide on the inner side of the arc groove 11, and at the same time drive the adjustment plate 9 to flip, so as to adjust the storage space in the metering cylinder 4, and change from storing one raw material to storing two raw materials, which is enough to meet the production needs of refractory bricks with different properties, and greatly improve the convenience of the device. Finally, when the adjustment plate 9 needs to be retracted during reset, the above operation can be repeated in reverse.

[0036] In order to improve the stability of the device during operation, guide grooves 18 are opened on the outer wall of the rectangular rod 14 and at the position corresponding to the moving block 16. The side walls of the moving block 16 are fixedly connected with guide blocks 19, and the guide blocks 19 are slidably connected to the inner side of the guide grooves 18. The top of the threaded rod 17 is fixedly connected with a rotating block 20. Through the arrangement of the guide blocks 19 and the guide grooves 18, a guiding role can be played when the threaded rod 17 rotates to push the moving block 16 to slide downward, thereby preventing the moving block 16 from rotating with the threaded rod 17, thereby improving the stability of the device during operation.

[0037] In order to block the arc-shaped discharge port 7 while adjusting the storage space, a telescopic groove 21 is provided at the bottom of the adjustment plate 9 and at a position corresponding to the arc-shaped discharge port 7, a telescopic plate 22 is slidably connected to the inner side of the telescopic groove 21, and three upper springs 23 are fixedly connected between the inner side of the telescopic groove 21 and the top of the telescopic plate 22, the arc-shaped discharge port 7 is tilted near the side of the adjustment plate 9, and the telescopic plate 22 is tilted near the bottom end of the side of the adjustment plate 9;

[0038] When the adjusting plate 9 is driven to flip and adjust the storage space, the telescopic plate 22 will be driven to slide. At this time, the bottom end of the metering cylinder 4 will squeeze the telescopic plate 22 to limit its downward sliding. Then, when the telescopic plate 22 slides above the arc-shaped discharge port 7, the squeezing of the telescopic plate 22 will be released, and then the telescopic plate 22 will be pushed downward under the elastic force of the upper spring 23, thereby pushing the telescopic plate 22 into the arc-shaped discharge port 7, and the arc-shaped discharge port 7 below the two spaces separated by the adjusting plate 9 can be blocked. Then, when the adjusting plate 9 is adjusted back, the telescopic plate 22 will be driven to slide in the arc-shaped discharge port 7, and then when sliding out of the arc-shaped discharge port 7, the inclined surface of the side wall of the arc-shaped discharge port 7 will gradually squeeze the inclined surface of the bottom of the telescopic plate 22, thereby squeezing the telescopic plate 22 to slide upward into the telescopic groove 21, and gradually compressing the upper spring 23 until the telescopic plate 22 completely slides out of the arc-shaped discharge port 7.

[0039] In order to be able to accurately adjust the storage space adjusted in the metering cylinder 4, a pointer 24 is fixedly connected to the top of the adjustment plate 9, and a capacity scale groove 25 is opened at the top of the upper cylinder 8 and at a position corresponding to the pointer 24. Through the arrangement of the pointer 24 and the capacity scale groove 25, the position of the corresponding pointer 24 on the capacity scale groove 25 can be observed while moving the adjustment plate 9 to adjust the storage space, so that the storage space can be accurately adjusted, further improving the convenience of the device.

[0040] In order to be able to clean the inner wall of the changed space while adjusting the storage space of the quantitative cylinder 4, four movable chambers 26 are equidistantly opened inside the quantitative cylinder 4, and the inner sides of the four movable chambers 26 are slidably connected to movable plates 27, and the side walls of the partition 6 are slidably connected to scrapers 28, and the side walls of the scrapers 28 are fixedly connected to a pair of pull ropes 29, and the other ends of the pull ropes 29 pass through the inner sides of the movable chambers 26 and are fixedly connected to the side walls of the movable plates 27, and the outer walls of the quantitative cylinder 4 and the corresponding positions of the movable chambers 26 are provided with cleaning grooves 31, and the movable plates 27 are connected to the side walls of the partition 6. A straight rod 33 is fixedly connected to the side wall of the scraper 27 and the position corresponding to the cleaning groove 31, a U-shaped rod 32 for pushing the straight rod 33 to move is fixedly connected to the top of the adjustment plate 9 and the side away from the upper cylinder 8, and there is a certain distance between the U-shaped rod 32 and the straight rod 33, and the outer wall of the adjustment plate 9 is in contact with the outer wall of the upper cylinder 8 and the inner wall of the quantitative cylinder 4, and a lower spring 34 is fixedly connected between the side wall of the scraper 28 and the inner wall of the quantitative cylinder 4 and located outside the pull rope 29, and the arrangement of the lower spring 34 facilitates the scraper 28 to be pushed to reset;

[0041] When the threaded rod 17 is rotated to adjust the storage space in the metering cylinder 4, the movement of the adjusting plate 9 will drive the U-shaped rod 32 to move at the same time, and then when the U-shaped rod 32 moves to the side of the straight rod 33, the adjusting plate 9 is now moved away from the scraper 28, and then the U-shaped rod 32 will push the straight rod 33 to slide inside the cleaning groove 31, and at the same time drive the moving plate 27 to slide inside the moving cavity 26, and then pull the scraper 28 to slide on the side wall of the partition 6 through the pull rope 29, and gradually compress the lower spring 34, and then pull the scraper 28 to the other side, and then complete the adjustment of the internal space of the metering cylinder 4, and at the same time the adjusting plate 9 will scrape off the raw materials adhering to the inner wall of the upper cylinder 8 and the metering cylinder 4;

[0042] Then, when the adjusting plate 9 needs to be adjusted back, the U-shaped rod 32 will gradually release the squeezing of the straight rod 33, and then push the scraper 28 to reset under the elastic force of the lower spring 34, and at the same time drive the moving plate 27 to slide inside the moving cavity 26, thereby scraping off the raw materials adhered to the side wall of the partition 6, and then before the adjusting plate 9 is reset, the scraper 28 is completely reset to completely scrape off the raw materials adhered to the partition 6, and finally the adjusting plate 9 is turned over to reset the scraper 28 and insert it into the receiving groove 36;

[0043] When it is not necessary to fully open the adjustment plate 9 according to the amount of stored raw materials (the scraper 28 has not moved to the inner wall of the metering cylinder 4 at this time, so the side wall of the partition 6 cannot be completely cleaned when resetting), when it is necessary to adjust the adjustment plate 9 back to reset, the raw materials are first emptied, and then the straight rod 33 can be pushed to drive the scraper 28 to fully scrape the side wall of the partition 6, thereby improving the convenience of the device. At the same time, when the adjustment plate 9 is about to be reset to release the thrust on the straight rod 33, the straight rod 33 can be pushed back and forth to drive the scraper 28 to clean the side wall of the adjustment plate 9. Moreover, since the angles at both ends of the adjustment plate 9 are different when the adjustment plate 9 is rotated and reset, the threaded rod 17 can be rotated to move the position of the adjustment plate 9 to cooperate while pushing the straight rod 33 to clean the side wall of the adjustment plate 9 (the scraper 28 is made of soft rubber material and can be deformed when squeezed by the adjustment plate 9, so as to better clean the side wall of the adjustment plate 9). The side wall of the adjustment plate 9 is fully cleaned. If the original stored raw materials need to be stored later, they do not need to be cleaned.

[0044] In order to improve the stability of the device during operation, a guide roller 30 is rotatably connected to the inner side of the movable cavity 26 and at a position corresponding to the scraper 28, and the pull ropes 29 pass through the outer walls of the guide rollers 30. Through the setting of the guide rollers 30, when the movable plate 27 pulls the pull rope 29 to move, it can not only guide the movement of the pull rope 29, but also prevent the pull rope 29 from directly contacting the inner wall of the movable cavity 26, causing friction to the pull rope 29, affecting the service life of the pull rope 29, and improving the smoothness of the device during operation.

[0045] In order to avoid affecting the normal reset of the adjustment plate 9, a circular groove 35 is provided on the side wall of the adjustment plate 9 and at a position corresponding to the pull rope 29, and a receiving groove 36 is provided on the side wall of the adjustment plate 9 and at a position corresponding to the scraper 28. By setting the circular groove 35 and the receiving groove 36, the obstruction of the receiving pull rope 29 and the scraper 28 can be avoided when the adjustment plate 9 is reset, and there is a certain distance between the U-shaped rod 32 and the straight rod 33. Therefore, when the adjustment plate 9 is not completely reset, the scraper 28 has been reset, thereby effectively avoiding the adjustment plate 9 from being completely reset. The section plate 9 prevents the scraper 28 from resetting, and a discharge groove 37 is obliquely opened at the bottom end of the metering cylinder 4 and at a position corresponding to the storage groove 36. The setting of the discharge groove 37 facilitates the discharge of the raw materials scraped off by the scraper 28, and the discharge groove 37 is connected with the arc-shaped discharge port 7 for direct discharge (it should be noted that after the adjustment plate 9 resets the scraper 28 and cleans it, the raw materials in the discharge groove 37 must be cleaned before adding the stored raw materials to avoid mixing the two and affecting the production ratio of refractory bricks).

[0046] The basic principles, main features and advantages of the present invention are shown and described above.

[0047] Those skilled in the art should understand that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments and the specification only describe the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. These changes and improvements all fall within the scope of the present invention to be protected.
