Description

Technical Field

[0001] The invention relates to the field of refractory brick drying, and in particular to a device for quickly and evenly drying refractory materials. Background Art

[0002] Refractory materials refer to special materials that can maintain their physical and chemical properties under high temperature environment. They are mainly used to manufacture high temperature equipment such as kilns, boilers, and heat exchangers. Common refractory materials include refractory bricks, refractory castables, refractory fiber products, etc. Refractory bricks are mainly used for building the lining of high temperature kilns. The production process of refractory bricks usually includes steps such as raw material mixing, molding, drying and sintering. Among them, drying is a crucial link in the production process. If high-temperature sintering is carried out directly, the rapid evaporation of water will cause stress inside the brick body, thereby causing cracking or insufficient strength. Therefore, the main purpose of the drying process is to slowly remove moisture from the brick and prevent thermal stress damage.

[0003] In the prior art, when drying refractory bricks, operators usually stack the bricks on a support frame and then push the support frame into a high-temperature kiln for baking; however, since the high temperature in the kiln is mainly concentrated on the outside of the support frame, the temperature of the refractory bricks on the outside is higher, while the temperature of the refractory bricks on the inside is relatively lower, resulting in the inner bricks not being completely baked when the outer bricks are baked, which requires extending the baking time, but this may cause damage to the outer refractory bricks; in addition, during the loading and unloading process, the operator must enter the inside of the high-temperature kiln, which is more dangerous.

[0004] In the prior art, for example, the patent with publication number CN217604607U discloses a continuous drying furnace for refractory bricks, which circulates hot air on the surface of several refractory bricks placed on the surface of the rack through three air guide plates. After the refractory bricks are evenly dried, the electric roller drives the rack to slide out from the other end of the drying chamber, and controls the hydraulic rod to lower the rack to contact the surface of the support frame. After the dried refractory bricks are taken out, the next batch of refractory bricks are fixed to the surface of the rack in the same way for continuous drying. However, although this technology has improved some of the original problems, there are still aspects that need to be further optimized to better meet actual testing needs.

[0005] 1. The above-mentioned existing device can use the grid to limit the refractory bricks, and the hot air can contact the refractory bricks through the gaps on the grid. However, the surface of the grid is composed of multiple horizontal and vertical plates. Before the bricks are heated, their surfaces will be squeezed when they contact the grid, resulting in obvious squeeze marks on the surface. In addition, the grid will also block part of the area outside the bricks, so that the hot air cannot fully contact these blocked areas. As a result, after the bricks are dried, the color of the brick surface is inconsistent due to the uneven area in contact with the hot air and the area blocked by the grid. The squeeze marks and different color depths will reduce the yield rate of the bricks.

[0006] 2. After the bricks are dried, the above-mentioned prior art can be taken out of the drying room through the auxiliary rack of external equipment. However, when reinstalling the rack, manual participation is still required to control the auxiliary rack to correspond to the feeding place, that is, the operation process of loading and unloading is relatively cumbersome, so the efficiency of continuous drying is low. In addition, since it takes a long time to install and disassemble the rack, the hot air in the drying room will flow out during this process. When the next drying process is performed, the heat pump dryer is still required to pump sufficient hot air into the drying room, so the utilization rate of the hot air is low.

[0007] Therefore, under the above-stated viewpoint, there is still room for improvement in the existing refractory brick drying equipment. Summary of the invention

DETAILED DESCRIPTION

[0041] The following combination Figures 1 to 16 Embodiments of the present invention are described in detail.

[0042] The embodiment of the present application discloses a device for quickly and evenly drying refractory materials, which explains that the present application is mainly used in the process of drying refractory bricks. In terms of technical effect, it can support the bottoms of multiple refractory bricks, and can also limit the sides of the refractory bricks through auxiliary limiting devices to prevent the refractory bricks from shifting in position during the drying process; in particular, after the drying of a partial area of ​​the refractory brick is completed, the limiting device at the bottom of the refractory brick will drive the refractory brick to move downward, and at the same time expose the blocked areas on the bottom and sides of the refractory brick, so that the surface of the refractory brick can be evenly dried, avoiding color difference on the surface of the refractory brick.

[0043] Example 1: Reference Figure 1 , Figure 2 and Figure 3As shown, it includes a bottom plate 1, a drying box 10, a sliding groove 11, a rack 12, a sliding wheel 13 and a supporting unit 2. A drying box 10 with a U-shaped cross section is arranged on the upper end of the bottom plate 1. The sliding grooves 11 are symmetrically opened on the bottom plate 1, and a rack 12 with a U-shaped cross section and located in the drying box 10 is slidably arranged on the bottom plate 1. Sliding wheels 13 located in the corresponding sliding grooves 11 are symmetrically arranged at the bottom of the rack 12. Supporting units 2 for supporting the bottom of refractory bricks are commonly arranged on the inner walls on both sides of the rack 12.

[0044] That is, when the rack 12 is driven by an external force, it can slide in the sliding groove 11 through the sliding wheel 13, and the sliding groove 11 limits and guides the rack 12 through the sliding wheel 13, so that the rack 12 can enter the drying box 10, and hot air is supplied to the inside of the drying box 10 through an external air supply device. The drying box 10 retains the hot air and heats and dries the refractory bricks on the supporting unit 2 through the hot air. When the refractory bricks are heated, the rack 12 can be driven by an external force to move out from the other side of the drying box 10.

[0045] Continue to refer to Figure 3 , Figure 4 and Figure 5 As shown, the supporting unit 2 is used to support the bottom of the refractory bricks; specifically, the supporting unit 2 includes a longitudinal groove 20, a longitudinal plate 21, a rectangular frame 22, a transverse groove 23, a transverse block 24, a supporting strip 25 and a reset spring 26. Several longitudinal grooves 20 are symmetrically arranged on the inner walls of both sides of the rack 12, and the longitudinal grooves 20 are evenly distributed along the extension section of the rack 12. A longitudinal plate 21 is slidably arranged in the longitudinal groove 20, and a rectangular frame 22 is slidably arranged between the front and rear corresponding longitudinal plates 21, that is, when the rectangular frame 22 is driven by an external force, the longitudinal plate 21 can be driven to move up and down in the corresponding longitudinal groove 20, and the longitudinal groove 20 can limit and guide the rectangular frame 22 through the longitudinal plate 21.

[0046] The inner walls on both sides of the rectangular frame 22 are jointly provided with a plurality of transverse grooves 23 distributed along the extension section thereof, and transverse blocks 24 are symmetrically slidably arranged between the corresponding transverse grooves 23 on both sides, that is, the transverse blocks 24 can move left and right under the limiting guidance of the corresponding transverse grooves 23 when driven by external force.

[0047] The opposite ends of the transverse blocks 24 on both sides of the transverse groove 23 are provided with installation grooves, and supporting strips 25 are installed between the corresponding installation grooves inside the transverse grooves 23 on both sides, that is, the transverse blocks 24 can drive the corresponding supporting strips 25 to move synchronously when moving, and the two adjacent supporting strips 25 can support the bottom of the refractory bricks together, and when the unobstructed area of ​​the refractory bricks is dried, the transverse blocks 24 are driven by external force to drive the corresponding supporting strips 25 to move, and the two supporting strips 25 move in relative directions, and the distance between the two supporting strips 25 is reduced, and the bottom area of ​​the refractory bricks that have been dried is moved together, so that the area of ​​the refractory bricks blocked by the supporting strips 25 can be in contact with the hot air for drying.

[0048] A reset spring 26 is provided between the inner wall of the longitudinal groove 20 and the longitudinal displacement plate 21. In the initial state, when the supporting strip 25 does not support the refractory bricks, the reset spring 26 can drive the rectangular frame 22 to correspond to the inner top wall of the corresponding longitudinal groove 20 through the longitudinal displacement plate 21. When the supporting strip 25 supports the refractory bricks, since the weight of multiple refractory bricks is greater than the thrust of the reset spring 26, the rectangular frame 22 is driven by the weight of the corresponding refractory bricks to compress the corresponding reset spring 26 and drive the longitudinal displacement plate 21 to move to the inner bottom wall of the corresponding longitudinal groove 20.

[0049] Reference Figure 6 and Figure 7 As shown, a driving assembly 3 for driving the transverse block 24 to move is provided on the inner walls on both sides of the rack 12; specifically, the driving assembly 3 includes a guide groove 30, a driving plate 31 and a driving shaft 32, and a plurality of rectangularly distributed guide grooves 30 are provided on the inner walls on both sides of the rack 12, and two adjacent guide grooves 30 are symmetrically distributed, two guide grooves 30 form a group, and a plurality of groups of guide grooves 30 correspond one to one with the transverse blocks 24 in the adjacent transverse grooves 23, a driving plate 31 is provided on the lower side of the transverse block 24, and a driving shaft located in the corresponding guide groove 30 is provided on one side of the driving plate 31 32, the driving plate 31 can drive the corresponding transverse block 24 to move when driven by an external force, and when the rectangular frame 22 descends, it will indirectly drive the driving plate 31 to descend synchronously, and the descent of the driving plate 31 will drive the driving shaft 32 to descend synchronously and slide in the corresponding guide groove 30, the guide groove 30 will limit and guide the driving shaft 32, and indirectly drive the corresponding transverse block 24 to move in the corresponding transverse groove 23 through the driving shaft 32, and the two guide grooves 30 are symmetrically distributed, so the two corresponding supporting strips 25 will also move in relative directions.

[0050] Reference Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, a plurality of snap-in cavities 40 corresponding to the adjacent longitudinal grooves 20 are provided on both sides of the storage rack 12, and one side of the snap-in cavity 40 is connected to the corresponding longitudinal groove 20, and the other side is connected to the outside of the storage rack 12, and a snap-in assembly 4 for limiting the rectangular frame 22 is provided in the snap-in cavity 40; specifically, the snap-in assembly 4 includes a snap-in cavity 40, a snap-in groove 41, a snap-in plate 42, a spring cavity 43, a pull spring 44, a contact strip 45 and a receiving groove 46, and the snap-in groove 41 is provided on the side of the longitudinal moving plate 21 facing the snap-in cavity 40, and a snap-in plate 42 is slidably provided in the snap-in cavity 40, and the side of the snap-in plate 42 away from the snap-in groove 41 is an inclined surface, and the inclined surface is inclined toward one side of the drying box 10, that is, the snap-in plate 42 can move back and forth in the snap-in cavity 40 when driven by external force.

[0051] A spring cavity 43 is also provided on the inner wall of the snap-fit ​​cavity 40, and one side of the snap-fit ​​plate 42 extends into the spring cavity 43. A pulling spring 44 is provided between the inner wall of the spring cavity 43 and the snap-fit ​​plate 42. In the initial state, the pulling spring 44 applies a pulling force to the corresponding snap-fit ​​plate 42 so that one side of the snap-fit ​​plate 42 is not in the snap-fit ​​groove 41. That is, at this time, the rectangular frame 22 is pressed by the heat-resistant bricks and moves downward.

[0052] A plurality of abutting strips 45 corresponding to the clamping plates 42 are provided on one side of the drying box 10, and a receiving groove 46 corresponding to the clamping plates 42 is also provided in the drying box 10, and the receiving groove 46 extends to the other side of the drying box 10, that is, when the storage rack 12 is moved onto the bottom plate 1, the storage rack 12 moves toward the direction of the drying box 10, and the inclined surface on one side of the clamping plate 42 will contact the end of the abutting strip 45, and then the clamping plate 42 is indirectly driven by the inclined surface to move toward the clamping groove 41, and finally inserted into the clamping groove 41 to indirectly limit the rectangular frame 22. At this time, the rectangular frame 22 will not move downward due to the pressure of the heat-resistant bricks, and then the refractory bricks can be placed on the supporting strip 25.

[0053] After placement, continue to push the storage rack 12 to move into the drying box 10 to dry the heat-resistant bricks. At this time, the end of the clamping plate 42 will contact the inner wall of the drying box 10, and continue to indirectly limit the rectangular frame 22. When a part of the refractory bricks is dried, continue to drive the storage rack 12 to move a distance. At this time, the end of the clamping plate 42 will correspond to the receiving groove 46. Without the restriction of the conflicting strip 45 and the inner wall of the drying box 10, the clamping plate 42 will move into the receiving groove 46 under the push of the corresponding pull spring 44, and the other side will no longer be inserted into the clamping groove 41.

[0054] That is, at this time, the rectangular frame 22 is no longer limited, and it will descend under the pressure of the heat-resistant bricks, and the supporting strip 25 will also change its position to reveal the position where the heat-resistant bricks are blocked. When the heat-resistant bricks are dried, the storage rack 12 is pushed out of the drying box 10, and the clamping plate 42 is also moved out from the opening on one side of the accommodating groove 46. Then, the dried heat-resistant bricks are removed from the supporting strip 25. At this time, the rectangular frame 22 is no longer pressed by the refractory bricks, so it will move to the initial position under the push of the corresponding reset push spring 26. When the corresponding storage rack 12 continues to move onto the bottom plate 1, the oblique surface at the end of the corresponding clamping plate 42 is driven by the resistance strip 45 and will continue to be inserted into the corresponding clamping groove 41.

[0055] Example 2: Continue to refer to Figure 5 As shown, on the basis of the first embodiment, in order to adapt to refractory bricks of various widths, a plurality of threaded grooves 5 penetrating the outer walls on both sides of the transverse moving block 24 are provided, and the supporting strips 25 are slidably connected with the corresponding mounting grooves, a bolt 50 is inserted into the threaded groove 5 on one side, and the bottom of the bolt 50 penetrates through one side of the corresponding supporting strip 25, and is threadedly connected with the corresponding threaded groove 5 and the supporting strip 25 respectively. When the width of the refractory brick is low and the two corresponding supporting strips 25 are insufficient to support the bottom of the heat-resistant brick, the bolt 50 is screwed at this time to push the two supporting strips 25 to slide in the corresponding mounting groove, so that the distance between the supporting strips 25 is reduced, and then the supporting strips 25 are fixed by inserting the corresponding bolts 50 into the threaded groove 5.

[0056] Example 3: Reference Fig.14 and Fig.15 As shown, on the basis of the first and second embodiments, in order to limit the side of the refractory bricks to prevent them from being deflected when the supporting strips 25 are moved, side limit units 6 are provided on the inner walls of both sides of the rack 12; specifically, the side limit units 6 include a limit frame 60, a transverse plate 61, a longitudinal plate 62, a support column 63, a lifting slot 64 and an adjusting screw 65, several limit frames 60 are distributed one by one on the inner side of the rack 12, and correspond one by one to the upper side of the rectangular frame 22, several transverse plates 61 and longitudinal plates 62 distributed horizontally and vertically are provided on the inner side of the limit frame 60, the transverse plates 61 and longitudinal plates 62 form several installation areas, and the supporting strips 25 at the lower ends of the several installation areas correspond one by one, the refractory bricks are placed from the installation area on the corresponding two supporting strips 25, and the transverse plates 61 and longitudinal plates 62 on the installation area can limit the side of the refractory bricks to prevent the refractory bricks from being skewed and offset when the supporting strips 25 are moved.

[0057] Several limit frames 60 are connected by support columns 63, and lifting grooves 64 are symmetrically provided on the inner walls on both sides of the storage rack 12. The two sides of the uppermost limit frame 60 extend into the corresponding lifting grooves 64 respectively, and an adjusting screw 65 is rotatably arranged inside the lifting groove 64 on one side. The adjusting screw 65 is threadedly connected to the limit frame 60, and one side of the adjusting screw 65 passes through the inner wall of the lifting groove 64 and the outer wall of the storage rack 12 and is located outside the lifting groove 64. That is, in order to adapt to refractory bricks of various heights, the side surfaces of refractory bricks of different heights can contact the horizontal plate 61 and the vertical plate 62. The operator can drive the adjusting screw 65 to rotate through an external drive, so that the entire limit frame 60 can be adjusted in the up and down directions.

[0058] Furthermore, when the supporting strip 25 drives the refractory bricks to move downward, since the limit frame 60 is stationary at this time, the sides of the refractory bricks that are blocked by the horizontal plate 61 and the vertical plate 62 are also exposed when the refractory bricks move downward, and can come into contact with hot air, so that the bottom and sides of the refractory bricks can come into contact with hot air, thereby improving the uniformity of drying the refractory bricks.

[0059] Example 4: Reference Fig.16 As shown, on the basis of the first, second and third embodiments, in order to simultaneously drive multiple racks 12 to move and enter the drying box 10 in sequence for drying, a plurality of racks 12 are slidably arranged on the bottom plate 1, and a connecting assembly 7 for connecting the racks 12 to prevent the racks 12 from being too far apart is arranged between the racks 12; specifically, the connecting assembly 7 includes a fixing groove 70 and a fixing bolt 71, the fixing grooves 70 are symmetrically arranged on both sides of the racks 12, and the fixing grooves 70 adjacent to the two racks 12 are commonly threadedly connected with a fixing bolt 71, and the multiple racks 12 are connected to each other by the fixing bolt 71, so that the sliding wheels 13 at the bottom of the multiple racks 12 can move at a uniform speed in the sliding groove 11 under the drive of external force, and after the refractory bricks in one rack 12 are dried, the next rack 12 can then enter the drying box 10, thereby reducing the loss rate of heat in the drying box 10.

[0060] During operation: the first step is to place the storage rack 12 on the base plate 1, and drive the storage rack 12 to move on the base plate 1 through external force, and the corresponding snap-fit ​​assembly 4 is driven by the resistance strip 45 to limit the rectangular frame 22. At this time, the refractory bricks can be placed on the supporting strip 25, and the side limit unit 6 will limit the side of the refractory bricks to prevent the refractory bricks from shifting in position during the subsequent drying process.

[0061] Step 2: Push the storage rack 12 into the drying box 10, and then use the drying box 10 to dry the refractory bricks. After the drying of a part of the refractory bricks is completed, the storage rack 12 is driven by external force to continue to move a distance into the drying box 10, so that the end of the clamping plate 42 is located in the accommodating groove 46, and the rectangular frame 22 is no longer indirectly limited by the clamping plate 42. It will move downward under the pressure of the corresponding refractory bricks, driving the refractory bricks to move synchronously, and the area of ​​the refractory bricks blocked by the side limit unit 6 will also be exposed, so that it can come into contact with the hot air.

[0062] Step 3: During the downward movement of the rectangular frame 22, the supporting strips 25 are moved by driving the component 3, so that the area at the bottom of the refractory bricks that is blocked by the supporting strips 25 is exposed and in contact with the hot air.

[0063] Step 4: Multiple racks 12 can be connected and expanded together through the connecting component 7, that is, multiple racks 12 can be driven to move synchronously at the same time. When the refractory bricks on a rack 12 are dried, it can be driven to move out of the drying box 10 synchronously, and the next rack 12 can be moved into the drying box 10 synchronously, thereby improving the drying efficiency of the refractory bricks in this application.

[0064] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered as exemplary and non-restrictive in all respects.
