Description

Technical Field

[0001] The invention relates to the technical field of chrome corundum brick production, in particular to a device for preparing hydrofluoric acid-resistant chrome corundum bricks for chemical waste incinerators. Background Art

[0002] Chrome corundum bricks, as a high-performance refractory material, are widely used in high-temperature, high-pressure and highly corrosive industrial equipment, especially in chemical waste incinerators, where the requirements for resistance to hydrofluoric acid erosion are particularly strict. The main mineral composition of chrome corundum bricks is α-Al2O3-Cr2O3 solid solution, which not only improves the refractory and corrosion resistance of the brick body, but also makes the high-temperature performance of chrome corundum bricks better than pure corundum products.

[0003] At present, the preparation of chrome corundum bricks is mostly carried out by pressing and forming, and the preparation process usually includes the following steps: Raw material preparation: The main raw materials are α-Al2O3 and Cr2O3, among which the content of α-Al2O3 generally reaches more than 95%, and the content of Cr2O3 is between 1% and 30%. In addition, in order to improve the sintering performance and forming performance, it is necessary to add appropriate amounts of flux and binder.

[0004] Raw material crushing and mixing: Raw materials are crushed to ensure uniform particle size and then mixed to ensure uniform distribution of components in the finished product.

[0005] Brick forming: The mixed raw materials are pressed and made into bricks of different shapes and sizes. Common brick shapes include rectangular, circular, fan-shaped, etc.

[0006] High-temperature sintering: The formed bricks are placed in a high-temperature environment for sintering. The temperature is generally between 1600℃ and 1800℃, and the time usually takes more than 40 hours, so that the various minerals in the brick body combine with each other to form a solid.

[0007] Finishing processing: After sintering, the chrome corundum bricks need to be polished and processed to ensure their smooth surface and accurate size.

[0008] Although the existing chrome corundum brick preparation process is relatively mature, there are still some problems in the actual production process. In the rough blank forming process, the crushed and mixed raw materials need to be quantitatively placed in the mold in sequence for centralized pressing and forming. However, in the process of raw material feeding: The piled raw materials squeeze each other, causing the raw materials at the feed port of the hopper to fall slowly or be blocked. This situation not only affects the production efficiency, but may also cause the amount of raw materials in the mold frame to be lower than the standard raw material level, resulting in uneven force inside the finished product after pressing and even uneven finished product, thus affecting the specifications, quality and overall performance of the final product.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] Example 1 Please see attached Figure 1-12 , the present embodiment is a preparation device of chrome corundum bricks resistant to hydrofluoric acid corrosion for chemical waste incinerators: it includes a frame 1, a storage bin 2 is fixedly connected to the frame 1, a feeding tube 3 is connected below the storage bin 2, a quantitative material transport hopper 4 is connected below the feeding tube 3, a material unloading and tamping component 5 is matched at the quantitative material transport hopper 4, the quantitative material transport hopper 4 is slidably connected to the frame 1, a lifting platform 6 is provided in front of the quantitative material transport hopper 4, a mold frame 7 is fixedly connected inside the lifting platform 6, a hydraulic plate 8 is provided at the upper end of the mold frame 7, and the hydraulic plate 8 is installed on the bracket 20, a fixed plate 9 is matched below the mold frame 7, a material transport platform 10 is matched below the fixed plate 9, and a finished product dividing plate 11 is provided above the material transport platform 10.

[0038] The frame 1 is formed by welding a plurality of square steels to each other, and the frame 1 plays a role of stabilizing support for the components. In order to increase the stability of the frame 1, fixing holes are reserved on the square steel below the frame 1, and expansion screws can be installed to fix the frame 1 to ensure the overall stability of the device. The storage bin 2 is located at the top of the frame 1, and the upper end of the storage bin 2 is the material inlet. The raw material particles after mixing and processing enter the storage bin 2 from the upper end of the storage bin 2. The storage bin 2 is placed at the top of the frame 1 because there are fewer components at the top of the frame 1, which provides sufficient operating space for the loading process of the storage bin 2, which is convenient for the loading process. The feeding barrel 3 is located at the storage bin Below the silo 2, the connection between the feeding barrel 3 and the storage silo 2 is funnel-shaped, which facilitates all the raw materials in the storage silo 2 to enter the feeding barrel 3. The feeding barrel 3 is placed horizontally on the frame 1, and the outlet of the feeding barrel 3 is located below the feeding barrel 3. The quantitative hopper 4 has the same size as the opening below the feeding barrel 3. The material unloading and compacting assembly 5 is located on the feeding barrel 3 and the quantitative hopper 4. Its purpose is to ensure that the feeding barrel 3 unloads the quantitative hopper 4 stably, and at the same time ensure that the raw materials entering the quantitative hopper 4 are in a compacted state, and ensure that the amount of raw materials is sufficient before film pressing. The mold frame 7 and the lifting platform 6 are located at the front end of the quantitative hopper 4. , and the lower end of the quantitative material transport hopper 4 is flush with the upper end of the mold frame 7. The mold frame 7 and the quantitative material transport hopper 4 are both topless and bottomless structures, which are convenient for the vertical drop of materials. The hydraulic plate 8 at the upper end of the mold frame 7 is connected with a hydraulic press, which is located at the front side of the storage bin 2. The hydraulic press is installed on the frame 1. The hydraulic press controls the lifting of the hydraulic rod. The size of the hydraulic plate 8 is just the same as the inner cavity of the mold frame 7. There is a fixed plate 9 at the bottom of the mold frame 7. The upper end of the fixed plate 9 just fits with the lower end of the mold frame 7. The fixed plate 9 bears the pressure of the hydraulic plate 8 pressing down. The material transport platform 10 below the fixed plate 9 is used for the transportation of the fixed plate 9. The right end of 10 is the feeding place, and the left end of the transport platform 10 is the discharging place. The fixed plate 9 enters from the right end of the transport platform 10, and then stays under the mold frame 7. After the hydraulic plate 8 is pressed, the lifting platform 6 rises, and the transport platform 10 with the fixed plate 9 and the pressed bricks moves to the left. The finished product dividing plate 11 is located on the left side of the mold frame 7. During the left movement of the fixed plate 9, the bricks on the fixed plate 9 hit the finished product dividing plate 11. The finished product dividing plate 11 is used to increase the gap between the bricks to facilitate air circulation between the bricks, which is beneficial to the uniform heating or heat dissipation of the bricks in the subsequent firing and curing process, thereby improving the quality of the finished product.

[0039] The material unloading and compacting assembly 5 includes a spiral feeding rod 501 and a polarizing disk 502. The spiral feeding rod is rotatably connected in the feeding barrel 3. The outside of the feeding barrel 3 is provided with a driver 503 for driving the spiral feeding rod 501 to rotate reciprocally. The polarizing disk 502 is rotatably connected to the quantitative material transport hopper 4. A first connecting rod 504 is eccentrically hinged on the polarizing disk 502. A connecting rod 505 is hinged at the other end of the first connecting rod 504. A plurality of second connecting rods 506 are hinged below the connecting rod 505. The lower end of the second connecting rod 506 is hinged to the quantitative material transport hopper 4.

[0040] The material feeding and compacting assembly 5 is mainly composed of two parts. One part is the feeding of the feeding barrel 3. The material of the feeding barrel 3 is transported horizontally by a spiral feeding rod 501. The middle of the spiral feeding rod 501 is a rotating shaft, and the outside is a spiral blade. The blade of the spiral feeding rod 501 is the same as the inner cavity of the feeding barrel 3. When the spiral feeding rod 501 rotates, the blade will push the material to move along the forward direction of the spiral feeding rod 501. The feeding barrel 3 is provided with a driver 501 outside to drive the spiral feeding rod 501 to rotate. 3. The driver 503 can drive the reciprocating rotation of the spiral feeding rod 501. The forward rotation speed and the number of revolutions of the spiral feeding rod 501 are higher than the reverse rotation speed and the number of revolutions. When the spiral feeding rod 501 pulls the feeding, there is a return movement at the outlet of the feeding barrel 3, which ensures that the material discharged from the feeding barrel 3 can evenly fill the quantitative material transport hopper 4; the other part is to make the raw materials in the quantitative material transport hopper 4 evenly distributed through vibration. The rear end of the quantitative material transport hopper 4 is connected to the polarization plate 501. 2. The polarization disk 502 is a circular disk-shaped structure, which can rotate in the quantitative material transport hopper 4. The first connecting rod 504 is eccentrically connected to the polarization disk 502. The polarization disk 502 rotates under the action of the driving force. Since the first connecting rod 504 is eccentrically hinged on the polarization disk 502, when the polarization disk 502 rotates, the first connecting rod 504 will drive the connecting rod 505 to reciprocate. The multiple groups of second connecting rods 506 under the connecting rod 505 transmit this reciprocating motion to the quantitative material transport hopper 4, so that the quantitative material transport hopper 4 vibrates with a certain amplitude. The quantitative material transport hopper 4 acts on the raw materials inside through this vibration, so that the raw materials can be compacted in the quantitative material transport hopper 4. When the quantitative material transport hopper 4 moves to the top of the mold frame 7, this vibration can also accelerate the falling of the raw materials. At the same time, the secondary vibration can also shake the mold frame 7 in contact with the quantitative material transport hopper 4, so that the raw materials in the mold frame 7 can also be evenly distributed. After pressing, it is guaranteed that the materials used for each brick are the same, thereby improving the quality of the product.

[0041] There is a driver 503 motor on the driver 503, and a reducer is installed between the driver motor and the driver disk 5034. When the driver motor is working, the driver disk 5034 is driven to rotate through the reducer. The side of the driver disk 5034 is simultaneously connected to the incomplete internal gear 5032 and the incomplete external gear 5033. The sum of the missing angles of the incomplete internal gear 5032 and the incomplete external gear 5033 is three hundred and sixty degrees. Since the teeth of the incomplete internal gear 5032 and the incomplete external gear 5033 are partially missing, their meshing with the connecting gear 5031 is carried out alternately. The module of the incomplete internal gear 5032 is greater than the module of the incomplete external gear 5033. The speed and number of revolutions of the connecting gear 5031 driven by the incomplete internal gear 5032 in the forward direction are greater than the speed and number of revolutions of the connecting gear 5031 driven by the incomplete external gear 5033 in the reverse direction. The rotation of the connecting gear 5031 drives the spiral feeding rod 501 to rotate.

[0042] Furthermore, in order to make the vibration amplitude in the quantitative material conveying hopper 4 adjustable, a slide groove 507 is provided in the polarization disk 502, and the slider 508 can slide horizontally in the slide groove 507. The adjusting screw 509 passes through the slider 508, and the adjusting screw 509 is threadedly connected to the slider 508. The position of the slider 508 in the slide groove 507 can be adjusted by rotating the adjusting screw 509, thereby adjusting the distance between the hinge point between the first connecting rod 504 and the polarization disk 502 and the center of the polarization disk 502. In addition, when the hinge point of the first connecting rod 504 is located at the center of the polarization disk 502, the rotation of the polarization disk 502 will not cause the vibration. The first connecting rod 504 is driven to move, so that the quantitative material transport hopper 4 does not vibrate, which can reduce the noise generated by the machine; the connecting rod 505 hinged at the other end of the first connecting rod 504 is an inverted T-shaped structure, and four second connecting rods 506 are hinged below the connecting rod 505, and the four second connecting rods 506 are evenly distributed. The quantitative material transport hopper 4 is provided with a hinge point hinged to the four second connecting rods 506, and the first connecting rod 504, the connecting rod 505 and the second connecting rod 506 are each provided with two groups, and the two groups of components are distributed on the left and right sides of the quantitative material transport hopper 4, providing a stable vibration effect for the quantitative material transport hopper 4.

[0043] The quantitative material transport hopper 4 is used to receive the raw materials dropped from the feeding barrel 3 and transport the raw materials to the mold frame 7. The fixed quantitative material transport hopper 4 has loading and transportation functions. The first telescopic rod 13 is located on the frame 1 behind the quantitative material transport hopper 4. The first telescopic rod 13 is a telescopic rod-shaped structure fixed on the frame 1 and is used to push the quantitative material transport hopper 4 to move. At the same time, in order to ensure that the raw materials will not fall at the outlet of the feeding barrel 3 after the quantitative material transport hopper 4 moves, a baffle plate 12 is installed behind the quantitative material transport hopper 4. The top surface of the baffle plate 12 is flush with the quantitative feeding hopper, and the left and right sides of the baffle plate 12 are wider than the quantitative material transport hopper 4. The connecting rod 505 and the second connecting rod 506 are located below the baffle plate 12. A groove-shaped or track-shaped slide 14 is opened on the frame 1, and the baffle plate 12 is located in the slide 14. The slide 14 is used to accommodate the baffle plate 12 and allow the baffle plate 12 to slide inside it. The design of the slide 14 ensures the stability and accuracy of the baffle plate 12 and the quantitative material transport hopper 4 during movement.

[0044] The lifting platform 6 is located on the left and right sides of the mold frame 7. Four second telescopic rods 16 are installed between the lifting platform 6 and the frame 1. The four second telescopic rods 16 are synchronously extended and retracted to ensure the synchronization of the lifting and lowering of the lifting platform 6. The two sides of the lifting platform 6 are higher than the mold frame 7. The protrusions 15 on both sides of the lifting platform 6 play a guiding role in the movement of the quantitative material transport hopper 4. When the material in the quantitative material transport hopper 4 is released, since the top of the mold frame 7 is flush with the bottom of the quantitative material transport hopper 4, the material will fall directly into the mold frame 7, ensuring that the material can be accurately and evenly filled into the mold frame 7. The second telescopic rod 16 has precise telescopic control capabilities, thereby ensuring the stability and accuracy of the mold frame 7 during the lifting process. At the beginning of the lifting platform 6, the lifting platform 6 places the mold frame 7 above the fixed plate 9. After the hydraulic plate 8 is pressed, the lifting platform 6 drives the mold frame 7 to move upward, so that the fixed plate 9 can drive the formed brick to move to the left. Then the lifting platform 6 drives the mold frame 7 to fall onto another fixed plate 9, waiting for the falling and stamping on the lower side.

[0045] The material transport platform 10 is used for transporting the fixed plate 9. The two conveying wheels 1001 and the conveyor belt 1002 in the material transport platform 10 are serrated, which can improve the interaction force between the conveying wheels 1001 and the conveyor belt 1002. The conveying wheels 1001 are wheels located at both ends of the material transport platform 10. A control motor is installed on the conveying wheels 1001, and the conveying wheels 1001 are driven to rotate by the rotation of the motor. The conveyor belt 1002 is sleeved on the two conveying wheels 1001, and the conveyor belt 1002 is in a tensioned state. A plurality of equally spaced blocks 1003 are provided on the conveyor belt 1002. These blocks 1003 are used for positioning the fixed plate 9. The blocks 1003 protrude upward on the conveyor belt 1002 to clamp the fixed plate 9 to prevent it from sliding during transportation. Or rolling, the height of the block 1003 is the same as the thickness of the fixed plate 9, each group of blocks 1003 can only transport one fixed plate 9 at a time, the support rod 1004 is a rod-shaped structure fixedly connected to the frame 1 of the lifting platform 6, the upper end of the support rod 1004 is flush with the upper surface of the conveyor belt 1002, the support rod 1004 is located directly below the mold frame 7, and the support rod 1004 is designed to provide support under the conveyor belt 1002. When the hydraulic plate 8 punches the mold frame 7, the support rod 1004 supports the bottom of the fixed plate 9 to ensure that the fixed plate 9 will not move downward during the downward punching process of the hydraulic plate 8, thereby ensuring the compaction of the brick blank punching, and at the same time avoiding the downward pressure of the fixed plate 9 to damage the conveyor belt 1002, thereby improving the practical life of the device.

[0046] A material plate locator is provided at the feeding end of the material transport platform 10. The function of the material plate locator is to align the middle of the fixed plate 9 with the middle of the material transport platform 10. When the fixed plate 9 moves to the bottom of the mold frame 7, it is ensured that the midpoint of the mold frame 7 and the midpoint of the fixed plate 9 are on the same vertical line. The tip of the finished dividing plate 11 is facing the center of the mold frame 7. When two rows of bricks are pressed in sequence in the mold frame 7, there is one finished dividing plate 11. The finished dividing plate 11 increases the distance between the two rows of bricks, which is convenient for subsequent firing and maintenance work.

[0047] Furthermore, there are two symmetrically distributed guard plates 17 in the material plate positioner. The two guard plates 17 are symmetrical about the longitudinal section of the middle of the material transport platform 10. The two guard plates 17 are used to guide and position the fixed plate 9. The first support rod 18 and the second support rod 19 are located below the guard plate 17. The first support rod 18 is located on the right side of the guard plate 17, and the second support rod 19 is located on the left side of the guard plate 17. The guard plate 17 is fixedly mounted on the frame 1 by the first support rod 18 and the second support rod 19. The placement of the guard plate 17 can prevent the fixed plate 9 from being moved during the conveying process. Offset, while ensuring that the middle part of the fixed plate 9 moves along the middle part of the material transport platform 10, the two guard plates 17 are distributed in an "eight" shape, and the guard plates 17 gradually narrow after approaching the input end of the material transport platform 10, thereby achieving the effect of positioning the middle part of the fixed plate 9, and the finished dividing plate 11 is designed as a conical structure. This shape helps to gradually increase the gap between the two rows of bricks during the material dividing process. The surface of the finished dividing plate 11 is a smooth structure, which can reduce the friction between the finished dividing plate 11 and the bricks, and does not affect the movement of the bricks with the fixed plate 9.

[0048] Example 2 The structure is the same as the above embodiment. Fig.13 As shown, the specific difference of this embodiment is that a screw rod 21 is fixedly connected to the guard plate 17, the second support rod 19 is provided with a through hole matching the screw rod 21, and fixing bolts 22 threadedly connected to the screw rod 21 are provided on both sides of the through hole.

[0049] The guard plate 17 is fixedly connected with a screw rod 21. The main function of the screw rod 21 is to provide an adjustable connection point, allowing the spacing between the guard plate 17 and the second support rod 19 to be adjusted by rotating the fixing bolt 22. The spacing between the two second support rods 19 is fixed. After the guard plate 17 is adjusted, the spacing between the two guard plates 17 also changes accordingly. The second support rod 19 is provided with a through hole that cooperates with the screw rod 21. The through hole allows the screw rod 21 to pass through the second support rod 19, thereby connecting the guard plate 17 to the second support rod 19. Both sides of the second support rod 19 are provided with There is a fixing bolt 22 that cooperates with the screw rod 21. Since the screw rod 21 and the fixing bolt 22 are threadedly connected, after loosening the fixing bolt 22, the guard plate 17 and the screw rod 21 can be moved in the through hole. By sliding the guard plate 17 to the desired position and then re-tightening the fixing bolt 22, the new position of the guard plate 17 can be fixed. Once the spacing between the guard plates 17 is adjusted to a suitable width, the fixing bolt 22 will be tightened, thereby firmly fixing the guard plate 17 on the second support rod 19, thereby guiding the corresponding fixing plate 9.

[0050] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
