Description

Technical Field

[0001] This invention belongs to the field of industrial kiln technology, and specifically relates to a layered crossbeam structure, a double-layer roller kiln, and an installation method. Background Technology

[0002] Kilns are key high-temperature firing equipment in the ceramics industry. To improve land utilization, increase output, reduce energy consumption, and lower production costs, double-layer roller kilns have emerged and become widely used. However, a long-standing problem that has plagued the industry and seriously affected product quality and production stability has also arisen—the problem of dirt falling from the crossbeams of the partition layers and contaminating the ceramic products in the lower layer. Summary of the Invention

[0003] The purpose of this invention is to provide a layered beam structure, a double-layer roller kiln, and an installation method to solve one or more technical problems existing in the prior art.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: This invention discloses a partition beam structure, comprising: A crossbeam extends along the width of the kiln and includes two connecting ends that are respectively connected to the kiln walls on both sides. A spacer, wherein the spacer is provided with a groove for the crossbeam to be inserted; A stop member, which is connected to and encloses the crossbeam.

[0005] The present invention has at least the following beneficial effects: The two connecting ends of the crossbeam along the width of the kiln are respectively connected to the kiln walls on both sides, thus fixing the crossbeam relative to the kiln walls. The partition has a groove, and the partition and the crossbeam are mutually reinforced, allowing the crossbeam to be embedded in the groove. The baffle connects to the partition and wraps around the crossbeam, sealing the opening of the groove and preventing kiln flue gas from directly contacting the crossbeam, reducing the amount of deposits on the crossbeam. Even if deposits fall off the crossbeam, they will be blocked by the connected partition and baffle, preventing them from falling onto the billet or product, effectively preventing product contamination.

[0006] As a further improvement to the above technical solution, the spacer is provided with a mounting groove, and the stop is engaged in the mounting groove.

[0007] As a further improvement to the above technical solution, the mounting groove is connected to the recess.

[0008] As a further improvement to the above technical solution, the mounting groove is connected to the lower end face of the partition, the groove is located above the mounting groove, and the cross-section of the crossbeam perpendicular to the kiln width direction is square.

[0009] As a further improvement to the above technical solution, the mounting groove is a T-shaped groove, and the baffle is embedded in the mounting groove along the width direction of the kiln.

[0010] As a further improvement to the above technical solution, the stop member is recessed to form a limiting groove, and the partition beam structure is configured such that when the partition member is connected to the stop member, the groove communicates with the limiting groove and forms a cavity for the beam to be embedded.

[0011] As a further improvement to the above technical solution, the partition is hollow along the kiln length direction to form a first weight-reducing cavity, and the first weight-reducing cavity is connected to the groove.

[0012] As a further improvement to the above technical solution, the crossbeam is hollow along the width direction of the kiln to form a second weight-reducing cavity.

[0013] The present invention discloses a double-layer roller kiln, comprising the partition beam structure described in any of the above claims.

[0014] The present invention has at least the following beneficial effects: the connecting partition and the baffle wrap around the crossbeam, which not only prevents the flue gas from adhering to the crossbeam, but also prevents the adhering material on the crossbeam from falling into the lower space of the double-layer roller kiln, thus preventing the green body conveyed in the lower space from melting with the adhering material, which would lead to a decline in the quality of ceramic products.

[0015] This invention discloses an installation method applied to the partition beam structure described in any of the above claims, the installation method comprising the following steps: Connect the two connecting ends of the crossbeam to the kiln walls on both sides respectively; The partition is placed on the crossbeam, so that the crossbeam is embedded in the groove; The stop is connected to the spacer.

[0016] The present invention has at least the following beneficial effects: it enables the simple, quick, and efficient installation of the partition beam structure. Attached Figure Description

[0019] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0020] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0021] In the description of this invention, the use of terms such as "a number" means one or more, with "more than" meaning two or more. Terms like "greater than," "less than," and "exceeding" are understood to exclude the stated number, while terms like "above," "below," and "within" are understood to include the stated number. The use of terms like "first," "second," and "third" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, the number of indicated technical features, or the sequential relationship between indicated technical features.

[0022] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0023] In related technologies, most existing partitions of double-layer roller kilns use high-temperature resistant and load-bearing silicon carbide beams that run through both side walls as supports. Multiple layers of staggered refractory material are laid on the beams for sealing to prevent mutual interference between the upper and lower layers due to factors such as crossfire, gas leakage, and kiln pressure fluctuations, which would affect product quality.

[0024] Existing crossbeams are generally protruding or exposed at the bottom of the partition. During the high-temperature firing process of ceramic products, the mixture of decomposition products, dust and water vapor can easily adhere to the crossbeams during flue gas flow. When the pressure of the combustion flue gas in the kiln flues greatly or the temperature rises and falls, causing the adhered substances to expand and contract frequently, resulting in cracks, or when these adhered substances accumulate to a certain weight, they will fall off the crossbeams and fall directly onto the surface of the body, where they fuse with the glaze and / or colorant, forming "dirty" defects such as lumps, burrs, and spots, causing the ceramic products to be downgraded or scrapped.

[0025] Among them, the decomposition products are formed by the decomposition of carbonates, sulfates, carbons, etc. in the body or glaze at high temperature; the dust is generated by the friction between the brick blank and the roller during operation; the combustion products of natural gas are mainly water and carbon dioxide, which is one of the sources of water vapor in the flue gas.

[0026] Reference Figures 1 to 5 The following are several embodiments of a layered crossbeam structure, a double-layer roller kiln, and an installation method of the present invention.

[0027] like Figures 1 to 4 As shown, the partition beam structure 400 of this embodiment of the invention includes a beam 500, a partition 600, and a stop 700.

[0028] It is understood that the crossbeam 500 extends along the width direction of the double-layer roller kiln 800 and its two ends are connection ends. The double-layer roller kiln 800 includes two kiln walls 820 located on the inner side and opposite to each other along the kiln width direction. One connection end is connected to one of the kiln walls 820, and the other connection end is connected to the other kiln wall 820, so that the crossbeam 500 is stably supported in the double-layer roller kiln 800.

[0029] It is understandable that the spacer 600 is provided with a groove 610, such as Figures 1 to 3 As shown, the groove 610 is used for the crossbeam 500 to be inserted, so that the spacer 600 covers a part of the crossbeam 500.

[0030] Understandably, the stop 700 is connected to the spacer 600, so that the stop 700 blocks the opening of the groove 610, and the crossbeam 500 is wrapped between the spacer 600 and the stop 700.

[0031] This design prevents the crossbeam 500 from directly contacting the flue gas inside the double-layer roller kiln 800, reducing the amount of deposits on the crossbeam 500. Even if the flue gas adheres to the crossbeam 500 along the gap between the partition 600 and the baffle 700, when the deposits on the crossbeam 500 fall off, they will be blocked by the partition 600 or the baffle 700 and will not fall onto the product, thus effectively preventing the product from getting dirty.

[0032] In some embodiments, the spacer 600 and the stop 700 can be securely connected by means of welding, gluing or bolting.

[0033] In this embodiment, the spacer 600 is provided with a mounting groove 620, such as Figure 2 and Figure 3 As shown, the stop 700 is installed in the mounting slot 620 by a snap-fit ​​connection.

[0034] With this configuration, the stop 700 can obtain support through the groove wall of the mounting groove 620, making installation quick and eliminating the need for pre-drilling holes and bolts, thus enabling rapid installation of the interlayer beam structure 400.

[0035] Understandably, since the crossbeam 500 extends along the width of the kiln, the groove 610 also extends along the width of the kiln and connects the two opposite end faces of the partition 600.

[0036] It is understandable that the length direction of the double-layer roller kiln 800 is the kiln length direction, and the kiln length direction is perpendicular to the kiln width direction along the horizontal direction.

[0037] In some embodiments, there are two mounting slots 620 and they are spaced apart along the length of the kiln or in the vertical direction. The groove 610 is located between the two mounting slots 620. The opening of the groove 610 is connected to the outer end face of the spacer 600. The groove 610 and the mounting slots 620 are independent of each other and do not communicate with each other.

[0038] Thus, taking the spacing between the two mounting slots 620 along the length of the kiln as an example, one end of the baffle 700 along the length of the kiln is engaged in one of the mounting slots 620, and the other end of the baffle 700 along the length of the kiln is engaged in the other mounting slot 620. The two ends of the baffle 700 are securely connected to the spacer 600 by being engaged in the two mounting slots 620 respectively. Since the groove 610 is located between the two mounting slots 620, the groove 610 and the baffle 700 are vertically aligned, so that the end face of the baffle 700 completely seals the opening of the groove 610, preventing the attached material from falling onto the lower layer of products.

[0039] It is understandable that the mounting groove 620 can be a Z-shaped groove, and correspondingly, both ends of the stop 700 along the length of the kiln are Z-shaped strips corresponding to the Z-shaped groove, with the Z-shaped strips extending along the width of the kiln.

[0040] In this embodiment, the mounting slot 620 and the recess 610 are connected, such as... Figures 1 to 3As shown. Specifically, the groove 610 is located inside the spacer 600, one end of the mounting groove 620 is connected to the outer end face of the spacer 600, and the other end of the mounting groove 620 is connected to the opening of the groove 610. Therefore, the crossbeam 500 can be embedded into the groove 610 through the mounting groove 620 and the opening of the groove 610. The groove 610 and the mounting groove 620 can be made on the spacer 600 at the same time, eliminating the need for repeated positioning, omitting the manufacturing steps and time cost of the spacer 600, and improving the structural accuracy of the spacer 600.

[0041] It is understandable that the mounting groove 620 can be connected to the upper end face, lower end face, or both end faces along the length of the kiln of the spacer 600.

[0042] It is understandable that the cross-sectional shape of the beam 500 perpendicular to the kiln width direction can be circular, triangular, etc.

[0043] In this embodiment, the mounting groove 620 is located below the groove 610. The mounting groove 620 is connected to the lower end face of the partition 600. The cross-sectional shape of the beam 500 along the direction perpendicular to the kiln width is square. Correspondingly, the cross-sectional shape of the groove 610 is also square.

[0044] Thus, when assembling the partition beam structure 400, the partition 600 can move downward above the beam 500, so that the beam 500 is embedded in the groove 610. Since the partition 600 is connected and fixed to the kiln wall 820, the partition 600 can obtain support through the wall surface of the connected square groove 610 and the end face of the square beam 500, so that the partition 600 can be stably erected above the beam 500 without the need for workers or lifting equipment to support the partition 600. This makes the assembly of the partition beam structure 400 simpler and facilitates subsequent assembly operations such as inserting the stop 700 into the installation groove 620 and connecting the stop 700 with the partition 600.

[0045] In some embodiments, the mounting groove 620 may be a dovetail groove. Specifically, the dovetail groove with a trapezoidal cross-section has a longer upper end and a shorter lower end, with the longer upper end of the dovetail groove communicating with the groove 610. Correspondingly, the stop 700 has a trapezoidal cross-section that is wider at the top and narrower at the bottom.

[0046] Thus, when the crossbeam 500 is relatively embedded in the groove 610, the stop 700 can be embedded into the trapezoidal mounting groove 620 along the width direction of the kiln. The two inclined end faces of the stop 700 along the length direction of the kiln abut against the two inclined groove surfaces of the dovetail-shaped mounting groove 620, so that the stop 700 and the spacer 600 are firmly engaged. The trapezoidal cross-section stop 700 and the spacer 600 with the dovetail-shaped mounting groove 620 have a simple structure and are inexpensive and easy to manufacture.

[0047] In other embodiments, the mounting slot 620 is a T-slot, such as... Figure 3As shown. Specifically, the mounting groove 620 has a T-shaped cross-section, which is larger at the top and smaller at the bottom. The upper end of the longer T-shaped mounting groove 620 is connected to the recess 610. Correspondingly, the stop 700 has a T-shaped cross-section.

[0048] Thus, when the crossbeam 500 is relatively embedded in the groove 610, the stop 700 can be embedded into the T-shaped mounting groove 620 along the width direction of the kiln. The lower end faces of the two longer ends of the T-shaped stop 700 along the length direction of the kiln respectively abut against the two longer groove end faces of the upper end of the T-shaped mounting groove 620, so that the stop 700 and the spacer 600 are firmly engaged, preventing the stop 700 from falling off the mounting groove 620. The stop 700 with a T-shaped cross-section and the spacer 600 with a T-shaped mounting groove 620 have a simple structure and are inexpensive and easy to manufacture.

[0049] Furthermore, the spacer 600 is connected to the baffle 700 and forms a cavity around it. The shape and size of the cavity, projected along the kiln width, correspond to the cross-sectional shape and size of the beam 500. Thus, when the baffle 700 is inserted into the mounting groove 620, its upper end face contacts the lower end face of the beam 500. The beam 500, spacer 600, and baffle 700 form a relatively stable whole through their contacting end faces, preventing relative movement between the beam 500 and the spacer 600 and baffle 700, thereby improving the integrity and stability of the layered beam structure 400.

[0050] In some embodiments, the cavity is a groove 610. Therefore, the lower end face of the crossbeam 500 located in the cavity is horizontally aligned with the communicating surface of the groove 610 and the mounting groove 620, and the upper end face of the stop 700 stably supports the lower end face of the crossbeam 500.

[0051] In other embodiments, the upper end of the baffle 700 is recessed downwards to form a limiting groove, and the cavity includes a groove 610 and a limiting groove. Therefore, in the partition beam structure 400, the upper end of the beam 500 is embedded in the groove 610, and the lower end of the beam 500 is embedded in the limiting groove. The baffle 700 restricts the movement of the beam 500 along the kiln length direction through the limiting groove, so that the beam 500, the partition 600, and the baffle 700 are relatively fixed, further improving the stability of the partition beam structure 400.

[0052] It is understandable that the spacer 600 has a hollow cavity forming a first weight-reducing chamber 630, such as Figure 1 and Figure 2 As shown, this design aims to reduce the weight and manufacturing cost of the spacer 600. The first weight-reducing cavity 630 extends along the length of the kiln and communicates with the groove 610, further reducing the manufacturing difficulty of the spacer 600.

[0053] It is understandable that the partition 600 has a grid-shaped structure along the length of the kiln, which ensures the weight reduction of multiple first weight-reducing cavities 630 while ensuring the structural stability of the partition 600.

[0054] It is understandable that the hollow crossbeam 500 forms a second weight-reducing cavity 510, such as... Figures 1 to 3 As shown, this is to reduce the weight and manufacturing cost of the crossbeam 500. The second weight-reducing cavity 510 extends along the extension direction of the crossbeam 500, that is, the second weight-reducing cavity 510 extends along the kiln width direction.

[0055] Understandably, the length of the partition 600 along the width of the kiln is set according to the width of the double-layer roller kiln 800. Correspondingly, the length of the baffle 700 along the width of the kiln is also set according to the width of the double-layer roller kiln 800. This allows the partition 600 and the baffle 700 to be arranged along the width of the kiln respectively, ensuring that the cavity formed after the partition 600 and the baffle 700 are connected can completely enclose the crossbeam 500 located inside the double-layer roller kiln 800. This ensures that the crossbeam 500 does not directly contact the flue gas, reduces the deposits on the crossbeam 500, and ensures that any falling deposits are blocked by the baffle 700.

[0056] In some embodiments, the length of the partition 600 along the kiln width direction is the inner kiln width of the double-layer roller kiln 800, and the length of the baffle 700 along the kiln width direction is the inner kiln width of the double-layer roller kiln 800, so that the partition 600 and the baffle 700 are integral, reducing installation steps and saving installation time.

[0057] In this embodiment, multiple spacers 600 are provided and arranged closely along the width of the kiln, and multiple baffles 700 are provided and arranged closely along the width of the kiln.

[0058] Thus, when a partition 600 is erected above the crossbeam 500, the corresponding retaining members 700 are inserted into the mounting groove 620 of the partition 600 along the kiln width direction. Compared to a single partition 600 and a single retaining member 700, the staggered assembly of multiple partitions 600 and multiple retaining members 700 allows for easier and less labor-intensive installation of the partition crossbeam structure 400.

[0059] like Figure 4 As shown, the double-layer roller kiln 800 of this embodiment includes a kiln wall 820 and a partition beam structure 400. The internal space of the double-layer roller kiln 800 is divided into an upper kiln body and a lower kiln body. Under the same output, the floor space is reduced by about half, reducing the construction cost of the factory and improving the space utilization rate. Moreover, the double-layer roller kiln 800 has significant energy saving and consumption reduction, and improves production efficiency and capacity.

[0060] Since the double-layer roller kiln 800 includes all the technical solutions of the above-mentioned partition beam structure 400, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0061] It is understandable that the double-layer roller kiln 800 has a connecting cavity 810 formed in the recessed two sides of the kiln wall 820 along the kiln width direction. The connecting cavity 810 is used for the crossbeam 500 to pass through and be fixedly connected to the kiln wall 820.

[0062] In some embodiments, the connecting cavity 810 is a cuboid cavity corresponding to the shape and size of the cross section of the beam 500. Therefore, along the kiln width direction, the sum of the lengths of the plurality of spacers 600 is the distance between the inner sides of the two kiln walls 820.

[0063] In this embodiment, the connecting cavity 810 is stepped. Specifically, along the direction from the inside of the kiln wall 820 outwards, the stepped connecting cavity 810 near the outside of the kiln wall 820 is smaller and corresponds to the size of the crossbeam 500, while the stepped connecting cavity 810 near the inside of the kiln wall 820 is larger and corresponds to the size of the partition crossbeam structure 400. The end face between the larger and smaller ends of the connecting cavity 810 is a stepped surface. Therefore, along the kiln width direction, the total length of the multiple partitions 600 is equal to the distance between the two stepped surfaces of the two connecting cavities 810. That is, the two partitions 600 with the greatest distance along the kiln width direction are respectively inserted into the larger ends of the two connecting cavities 810, preventing flue gas from penetrating into the gap between the inside of the kiln wall 820 and the partitions 600 and contacting the crossbeam 500, thus reducing the amount of deposits on the crossbeam 500.

[0064] It is understandable that when constructing the double-layer roller kiln 800, a connecting cavity 810 was reserved in advance for the installation of the crossbeam 500.

[0065] In some embodiments, along the width direction of the kiln, the length of the baffle 700 is equal to the length of the spacer 600, and the number of spacers 600 corresponds one-to-one with the number of baffles 700.

[0066] In other embodiments, along the kiln width direction, the length of the baffle 700 is greater than or less than the length of the spacer 600, so that the multiple baffles 700 and the multiple spacers 600 are arranged alternately. Therefore, the gap between two adjacent baffles 700 is staggered with the gap between two adjacent baffles 700 along the kiln width direction, further preventing the attachments on the crossbeam 500 from falling off.

[0067] like Figure 5 As shown, the installation method of this embodiment of the invention is applied to the partition beam structure 400, and the installation method includes steps S100, S200 and S300.

[0068] Step S100: Connect the two connecting ends of the crossbeam 500 to the kiln walls 820 on both sides respectively.

[0069] It is understandable that the two connecting ends can be fixed to the kiln walls 820 on both sides by bolt connection or embedded installation, so that the crossbeam 500 can be supported by the kiln walls 820 on both sides of the double-layer roller kiln 800 along the kiln width direction.

[0070] In some embodiments, during the construction of the double-layer roller kiln 800, step S100 is performed simultaneously with the kiln wall 820, so that the crossbeam 500 is installed at the same time during the construction of the double-layer roller kiln 800, ensuring that the crossbeam 500 is firmly connected to the kiln wall 820.

[0071] In other embodiments, step S100 is performed after the kiln wall 820 of the double-layer roller kiln 800 is built, so that the construction of the overall kiln wall 820 of the double-layer roller kiln 800 and the installation of the partition beam structure 400 are independent of each other, making the installation simpler.

[0072] In step S200, the spacer 600 is placed on the crossbeam 500 so that the crossbeam 500 is embedded in the groove 610.

[0073] It is understandable that, since the crossbeam 500 is fixedly connected to the kiln wall 820 and the crossbeam 500 is a square structure corresponding to the groove 610, when step S200 is performed, when the crossbeam 500 is relatively embedded in the groove 610, the spacer 600 can obtain support from the crossbeam 500, so that the spacer 600 can be stably built on the crossbeam 500.

[0074] Step S300: Connect the stop 700 to the spacer 600.

[0075] Understandably, the partition 600 is provided with an installation groove 620, and the stop 700 is inserted into the installation groove 620 of the partition 600 along the kiln width direction to block the opening of the groove 610 and solve the problem of dirt falling onto the crossbeam 500.

[0076] It is understandable that the interlayer beam structure 400 includes multiple partitions 600 and multiple baffles 700.

[0077] In some embodiments, after step S100, step S200 is performed multiple times to ensure that multiple spacers 600 are mounted on the crossbeam 500, with the crossbeam 500 embedded in multiple grooves 610; then step S300 is performed multiple times to insert multiple stops 700 into the mounting slots 620 of the end spacers 600, and then the multiple spacers 600 are moved along the multiple mounting slots 620 that are aligned and interconnected along the kiln width direction, so that the multiple stops 700 are aligned with the multiple spacers 600 one by one, thus completing the installation of the partition crossbeam structure 400.

[0078] In this embodiment, after step S100, steps S200 and S300 are performed alternately. Specifically, a partition 600 is first erected on the crossbeam 500, so that the crossbeam 500 is embedded in the groove 610. Then, the partition 600 is moved along the kiln width direction, so that the partition 600 is embedded in the connecting cavity 810 inside one of the kiln walls 820. Then, step S300 is performed, so that the stop 700 is embedded in the mounting groove 620. The above steps S200 and S300 are repeated to improve the installation efficiency of the partition crossbeam structure 400, without having to repeatedly move the stop 700.

[0079] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described.
