Description

Technical Field

[0001] This utility model relates to the field of ceramic jar technology, and in particular to an assembled ceramic jar. Background Technology

[0002] Earthenware jars are made from clay minerals through a series of processes including screening, grinding, mixing, shaping, drying, and sintering. Due to their safe raw materials, high chemical stability, and low cost, they are widely used in food, fermentation, wine storage, and chemical reactions.

[0003] Currently, large ceramic jars are difficult to manufacture due to their large size and weak structural support, especially those with a volume greater than 2000 liters. Furthermore, large ceramic jars are prone to cracking and deformation during the sintering process due to shrinkage and deformation, resulting in a very low yield. The low transportation efficiency and high breakage rate of large ceramic jars also lead to high transportation costs. Utility Model Content

[0004] The purpose of this invention is to facilitate the assembly of a ceramic jar-shaped structure through modular assembly, which not only improves the final yield rate but also significantly reduces transportation costs. To address the aforementioned shortcomings of existing technologies, a modular ceramic jar is proposed, comprising multiple arc-shaped petals, multi-toothed splines, and multiple tightening ropes.

[0005] Multiple arc-shaped petals are arranged sequentially along the circumference, and a sealing body is provided between the mating surfaces of any two adjacent arc-shaped petals. One end of each arc-shaped petal has a protrusion. Multiple spaced grooves are provided along the outer peripheral wall of the multi-tooth spline. Each protrusion is inserted into the corresponding groove, and a sealing body is provided between the mating surfaces of each protrusion and the corresponding groove. Multiple clamping ropes are arranged at intervals, and each clamping rope is used to clamp the multiple arc-shaped petals so that the multiple arc-shaped petals and the multi-tooth spline form a pottery jar-shaped structure.

[0006] Optionally, the mating surfaces of any two adjacent arc-shaped lobes can be mutually mating planes, sawtooth surfaces, or tenon-and-mortise surfaces.

[0007] Optionally, the sealing body is a brazing filler metal, adhesive, or laminated material.

[0008] Optionally, the adhesive layer can be made of polymer strips, wood chips, or hay.

[0009] Optionally, each of the protrusions has a tapered structure, and the taper of each of the protrusions is 2-5°.

[0010] Optionally, the arc length of each of the arc-shaped lobes in the circumferential direction is 0.3-1m.

[0011] Optionally, each of the tightening ropes is equipped with a tightening device, which is used to adjust the tightening force of the corresponding tightening rope.

[0012] Optionally, the clamping force of each of the said clamping ropes is not higher than 0.8 MPa.

[0013] Optionally, the multi-tooth spline is made of ceramic or polymer materials.

[0014] Optionally, the number of the tightening ropes is 3-9, and the distance between each tightening rope and the multi-tooth spline is not less than 0.1m.

[0015] In the assembled ceramic jar provided by this embodiment of the invention, multiple arc-shaped petals are arranged sequentially along the circumference, and a sealing body is provided between the mating surfaces of any two adjacent arc-shaped petals, thereby achieving a seal between the gaps between the arc-shaped petals. Furthermore, the multi-tooth spline has multiple spaced grooves along its outer circumferential wall, with each protrusion inserted into a corresponding groove, and a sealing body is provided between the mating surfaces of each protrusion and its corresponding groove. This not only achieves a seal between the multi-tooth spline and the arc-shaped petals, but also reduces stress concentration at the bottom of the arc-shaped petals through the cooperation of the protrusions and grooves.

[0016] Furthermore, each tightening strap is used to tighten multiple arc-shaped petals, allowing for easy assembly of these petals and multi-toothed splines into a ceramic jar-shaped structure. This tightening force ensures the structural strength of the final ceramic jar-shaped structure. Additionally, because this ceramic jar-shaped structure is assembled from multiple arc-shaped petals and multi-toothed splines, each structure is small in size. This not only avoids the problems of large green bodies and cracking / deformation caused by shrinkage during sintering, thus improving the final yield, but also facilitates transportation, reduces breakage, and lowers transportation costs.

[0017] In other words, the prefabricated ceramic jar provided by this utility model embodiment can not only improve the final yield rate by completing the assembly of the ceramic jar structure through prefabrication, but also greatly reduce the transportation cost. Attached Figure Description

[0026] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] Figure 1 This is a structural schematic diagram of an assembled ceramic jar provided in an embodiment of this utility model, as shown below. Figure 1 As shown, the assembled ceramic jar includes multiple arc-shaped petals 1, multi-toothed splines 2, and multiple tight-fitting rope straps 3.

[0028] Multiple arc-shaped lobes 1 are arranged sequentially along the circumference, and a sealing body 4 is provided between the mating surfaces of any two adjacent arc-shaped lobes 1 (see...). Figure 2 ). Figure 3 This is a schematic diagram of the bottom structure of an assembled ceramic jar provided in an embodiment of this utility model, as shown below. Figure 3 As shown, each arc-shaped petal 1 has a protrusion at one end, and the multi-tooth spline 2 has multiple grooves arranged at intervals along its outer peripheral wall. Each protrusion is inserted into the corresponding groove, and a sealing body 4 is provided between the mating surfaces of each protrusion and the corresponding groove. Multiple clamping ropes 3 are arranged at intervals, and each clamping rope 3 is used to clamp multiple arc-shaped petals 1 so that multiple arc-shaped petals 1 and multi-tooth spline 2 form a pottery jar-shaped structure (i.e., a barrel-shaped structure with an open top).

[0029] In the assembled ceramic jar provided by this embodiment of the utility model, multiple arc-shaped petals 1 are arranged sequentially along the circumference, and a sealing body 4 is provided between the mating surfaces of any two adjacent arc-shaped petals 1, thereby achieving the sealing of the gap between the arc-shaped petals 1. Furthermore, the multi-tooth spline 2 has multiple spaced grooves arranged along its outer peripheral wall, with each protrusion inserted into a corresponding groove, and a sealing body 4 is provided between the mating surfaces of each protrusion and its corresponding groove. This not only achieves the sealing of the gap between the multi-tooth spline 2 and the arc-shaped petals 1, but also reduces stress concentration at the bottom of the arc-shaped petals 1 through the cooperation of the protrusions and grooves.

[0030] Furthermore, each tightening rope 3 is used to tighten multiple arc-shaped petals 1, so that the multiple arc-shaped petals 1 and multi-tooth splines 2 can be easily assembled into a pottery jar-shaped structure. Thus, the tightening force ensures the structural strength of the final pottery jar-shaped structure. In addition, since the pottery jar-shaped structure is assembled from multiple arc-shaped petals 1 and multi-tooth splines 2, the size of each structure is small. This not only avoids the large size of the green body, but also prevents cracking and deformation of the jar body caused by shrinkage and deformation during the sintering process, thereby improving the final yield, but also facilitates transportation, reduces the breakage rate, and lowers transportation costs.

[0031] In other words, the prefabricated ceramic jar provided by this utility model embodiment can not only improve the final yield rate by completing the assembly of the ceramic jar structure through prefabrication, but also greatly reduce the transportation cost.

[0032] In this embodiment, the mating surfaces of any two adjacent arc-shaped lobes 1 are mutually mating planes (see...). Figure 4 ), serrated surface (see) Figure 5 ) or mortise and tenon joint (see Figure 6 Among them, a flat mating surface reduces the processing difficulty of the arc-shaped petal 1, while a serrated or riveted surface increases the connection strength between the arc-shaped petals 1 that are subsequently assembled together.

[0033] In addition, the sealing body 4 is made of brazing filler metal, adhesive, or laminate.

[0034] Specifically, when the sealing body 4 is brazing filler metal, the brazing process is adopted. First, each arc-shaped petal 1 is assembled along the mating surface. Then, the brazing filler metal is filled into the gap of the mating surface to ensure that the filler metal is fully and evenly filled. Finally, the brazing filler metal can be melted by overall low-temperature sintering or laser local heating to achieve the sealing effect. The selection of brazing filler metal is mainly based on low-temperature ceramic glaze and low-melting-point alloy brazing filler metal.

[0035] When the sealing body 4 is an adhesive, an adhesive bonding process is adopted. The selected adhesive is evenly coated on the mating surface with the arc-shaped petal 1, with a coating thickness of not less than 3 mm, and fully covering the mating surface. The adhesive can be a safe and non-toxic inorganic adhesive (mainly aluminosilicates and phosphates) or an organic adhesive (mainly natural materials such as silicone, blood, and egg white).

[0036] When the sealing body 4 is a laminated material, the laminated material is applied to the mating surface of the arc-shaped petal 1, ensuring that the laminated material completely covers the mating surface with a thickness of 3-5 mm. The selected laminated material needs to be able to withstand a positive pressure of not less than 1 MPa. Highly stable materials such as polymer strips, wood chips, and hay can be selected for the laminated material.

[0037] See Figure 3 Each protrusion has a conical structure with a taper of 2-5°, thereby improving the load-bearing capacity of the multi-tooth spline 2.

[0038] For example, the arc length of each arc-shaped lobe 1 in the circumferential direction (horizontal plane) is 0.3-1m. The multi-toothed spline 2 can be made of ceramic material or polymer material.

[0039] In this embodiment, each hoop rope 3 is equipped with a hoop clamp 5, which is used to adjust the clamping force of the corresponding hoop rope 3, thereby ensuring the structural strength after assembly.

[0040] For example, the clamping force of each clamping rope 3 is not higher than 0.8 MPa.

[0041] In one embodiment of this utility model, the clamp 5 can be equipped with an intelligent clamping system 6 to realize real-time monitoring and automatic adjustment of the stress state of the ceramic jar.

[0042] For example, the number of tightening ropes 3 is 3-9, and the distance between each tightening rope 3 and the multi-tooth spline 2 is not less than 0.1m. The multiple tightening ropes 3 are distributed to avoid the concentration of tightening force.

[0043] To better understand the structure of this prefabricated ceramic jar, the assembly of the prefabricated ceramic jar will be introduced with reference to two embodiments.

[0044] Example 1

[0045] Step S1: Design the pottery jar with a maximum diameter of 2 meters, a height of 2 meters, a bottom diameter of 1.5 meters, and a mouth diameter of 1 meter. Divide the jar into 8 equal parts, as shown in the attached diagram. Figure 1 As shown; the average thickness of the jar is 3 centimeters.

[0046] Step S2: Using a planar butt joint method, a mold for forming the arc petal 1 is made; common clay is selected and passed through a 20-mesh sieve, and water is added at a mass ratio not exceeding 25% to fully mix the clay, and then pressed into shape in the mold to obtain the arc petal 1 body; the body is dried and sintered to finally obtain the arc petal 1.

[0047] Step S3: Use brazing to seal the mating surfaces between the arc-shaped petals 1. First, assemble each arc-shaped petal 1 along the mating surface. Then, select a low-temperature glaze as the brazing filler and fill it into the gap between the mating surfaces, ensuring that the filler filler is fully and evenly distributed. Finally, use a laser to locally heat the gap between the mating surfaces to melt the brazing filler.

[0048] Step S4: Select high-density polyethylene as the material for the multi-tooth spline 2 at the bottom of the jar body, and process it into an 8-tooth spline with an outer diameter of 10 cm, as shown in the attached figure. Figure 3As shown; the multi-tooth spline 2 and the arc-shaped petal 1 have an arc-shaped groove with a depth of 5 mm on their mating surface; the multi-tooth spline 2 has a taper of 3 degrees; the mating surface between the multi-tooth spline 2 and the arc-shaped petal 1 is sealed using a lamination process, and low-density polyethylene with a thickness of 3 mm is selected as the lamination.

[0049] Step S5: Assemble the arc-shaped petal 1 and multi-tooth spline 2 that have completed steps S3 and S4, ensuring that all mating surfaces are in complete contact; then tighten the clamps with steel wire ropes at distances of 0.1 meters, 0.4 meters, 0.7 meters, 1 meter, 1.5 meters from the bottom of the jar and at the neck of the jar, adjust the fasteners, and install the intelligent clamping system 6, ensuring that the clamping force does not exceed 0.8 MPa.

[0050] The assembled ceramic jar obtained in Example 1 has a final volume of 3968 liters, which is much larger than the current mainstream ceramic jar market's large ceramic jar volume of 1000 liters.

[0051] Example 2

[0052] Step S1: Design the pottery jar to have a maximum diameter of 3 meters, a height of 1.5 meters, a bottom diameter of 2.6 meters, and a mouth diameter of 1.2 meters. Divide the jar into 12 equal parts; the average thickness of the jar is 3.5 centimeters.

[0053] Step S2: Select a serrated mating surface to make a mold for forming the arc-shaped petal 1, and make an arc-shaped punch with a height of 5 mm at the corresponding position so that there is an arc-shaped groove with a depth of 5 mm on the mating surface; select common clay that passes through a 20-mesh sieve and adds water with a mass ratio not exceeding 25%, mix the clay thoroughly, and then press it into shape in the mold to obtain the arc-shaped petal 1 body; after drying and sintering, the arc-shaped petal 1 is finally obtained.

[0054] Step S3: Select low-density polyethylene material as the interlayer, with a thickness of 3 mm and an arc-shaped protrusion height of 5 mm; install the interlayer onto the arc-shaped petal 1.

[0055] Step S4: Select high-density polyethylene as the material for the multi-tooth spline 2 at the bottom of the jar body, and process it into a 12-tooth spline with an outer diameter of 16 cm; the multi-tooth spline 2 and the arc-shaped petal 1 have an arc-shaped groove with a depth of 5 mm on their mating surface; the multi-tooth spline 2 has a taper of 5 degrees; install adhesive in the arc-shaped groove of the multi-tooth spline 2, and the adhesive is the same as in step S3.

[0056] Step S5: Assemble the arc-shaped petal 1 and multi-tooth spline 2 that have completed step S4, ensuring that all mating surfaces are in complete contact; then tighten the clamps with steel wire ropes at distances of 0.1 meters, 0.3 meters, 0.5 meters, 0.7 meters, 1 meter from the bottom of the jar and at the neck of the jar, adjust the fasteners, and install the intelligent clamping system 6, ensuring that the clamping force does not exceed 0.8 MPa.

[0057] The final volume of the assembled ceramic jar obtained in Example 2 is 8478 liters.

[0058] Table 1 Comparison of the effects of pottery jar techniques

[0059]

[0060] The technical effects of the assembled ceramic jar obtained in this embodiment are compared and analyzed with those of mainstream large ton jars on the market. The results are shown in Table 1. Wherein: storage efficiency (V1 / S1) = ceramic jar volume (V1) / floor area (S1), the larger the value, the higher the storage efficiency; transportation efficiency (V1 / V2) = ceramic jar volume (V1) / transport packaging volume (V2), the larger the value, the higher the transportation efficiency. The comparison results clearly show that the assembled ceramic jar obtained by this invention has significantly higher storage and transportation efficiencies than commonly available ceramic jars on the market, demonstrating a significant technical advantage.

[0063] 2. This assembled ceramic jar uses arc-shaped petals 1 for sintering, which reduces the amount of shrinkage during the sintering process. In addition, the weight of arc-shaped petals 1 is reduced relative to the weight of the jar body, avoiding problems such as deformation, cracking and collapse of the jar body caused by shrinkage during the sintering process. This effectively improves sintering efficiency and saves sintering costs.

[0064] 3. This prefabricated ceramic jar adopts an arc-shaped petal assembly method. The arc-shaped petal 1 facilitates transportation from the factory to the application site and greatly improves transportation efficiency, solving the problems of low transportation efficiency, high cost, and easy breakage of traditional large ceramic jars. In addition, the prefabricated ceramic jar can be assembled according to local conditions at the application site, effectively improving the utilization rate of the site.

[0065] 4. This prefabricated ceramic jar is secured by external steel wire ropes or steel strips, and the securing force can be adjusted according to the size, height, and weight of the materials contained in the jar, effectively reducing the stress on the jar itself and thus greatly improving the service life of the jar.

[0066] 5. This prefabricated ceramic jar can improve the corrosion resistance and food safety performance of the ceramic jar, realize intelligent monitoring and full life cycle management, improve warehousing and transportation efficiency, and has environmental protection and recycling value.
