Description

Technical Field

[0001] The invention relates to the technical field of incense burner processing, in particular to an earthenware burner body processing technology and an incense burner. Background Art

[0002] At present, in the domestic incense burner handicraft industry, the existing incense burners are made of copper, other metals, ceramics, glass, stone, precious wood, resin and chemical synthesis, etc., which can meet the aesthetic and usage needs of different consumers.

[0003] There are many different methods for making incense burners, but the processing often has the disadvantages of high energy consumption, high water consumption, destruction of natural resources, and pollution to the air, water sources, and land. Whether it is metal smelting, ceramic firing, or the production of chemical synthetic materials, a large amount of energy input is required, which not only increases production costs, but may also cause pollution to the air, water sources, and land. Especially in the production process of chemical synthetic materials, toxic and harmful substances may be released, affecting the balance of the ecological environment. Summary of the invention

[0004] Aiming at the problem of environmental pollution in the processing of incense burners in the prior art, the present invention provides a soil furnace body processing technology and an incense burner.

[0005] The present invention is achieved through the following technical solutions: A soil furnace body processing technology comprises the following steps: Step 1, adding water to soil, sand and gelling agent to form a mixed soil material; Step 2: pouring the mixed soil into a mold, and then tamping or extruding it to obtain a rough furnace body; Step three, after demoulding, the furnace body is dehydrated and dried and a protective agent is applied to obtain the furnace body.

[0006] Preferably, in step 1, by mass, the soil material in the mixed soil material is 10% to 60%, the sand material is 20% to 50%, the gelling agent is 3% to 18%, and the water is 5% to 15%.

[0007] Preferably, in step 1, the soil material is a deep layer of plain soil below the surface humus layer and 80 to 100 cm below the surface; The excavation method is to first dig out the surface humus layer, and then backfill it with the humus layer after the bare soil is taken; The deep-layer soil is mixed after being dried in the sun, ground, sieved and sterilized by high-temperature dry heat.

[0008] Preferably, the moisture content of the deep soil after drying is less than or equal to 3%; The mesh diameter of the sieve used for grinding and sieving is less than or equal to 2 mm; For high-temperature dry heat disinfection, the temperature is 180~200℃ and the time is 0.5~1h.

[0009] Preferably, in step 1, the sand material is preferably washed sand, with a mud content of less than or equal to 3% and a water content of less than or equal to 3%; The sand material is coarse sand alone, medium sand alone, or any combination of coarse sand, medium sand and fine sand, or any combination of the three, and the weight of fine sand when combined shall not exceed 50% of the total mass of the sand material; among which, the particle size of coarse sand is 0.5~3mm, the particle size of medium sand is 0.5~0.35mm, and the particle size of fine sand is 0.35~0.25mm.

[0010] Preferably, in step one, cement-based gelling materials, lime-based gelling materials, gypsum-based gelling materials, water glass, resin-based gelling materials, protein-based gelling materials, sugar-based gelling materials, starch-based gelling materials or derivative enhanced products with the above-class gelling materials as the main materials.

[0011] Preferably, in step 2, when the furnace body is formed by layered manual hammering and compaction or mechanical extrusion molding, the mixed soil material is spread layer by layer and compacted layer by layer.

[0012] Preferably, during tamping or extrusion molding, the compaction ratio between the thickness of the loose soil layer and the thickness of the compacted soil layer is greater than or equal to 1.3:1.

[0013] Preferably, in step 3, the dehydration and drying is carried out by natural air-drying or drying. When the natural air-drying is carried out, the time is greater than or equal to 3 days; when the drying is carried out, the temperature is greater than 200° C., and the drying time is based on the weight of the furnace body no longer decreasing; The protective agent is an environmentally friendly wall protective agent, an interface agent and a protein-based wall protective agent emulsion; When applying, mix the protective agent with water in a ratio of 1:2~1:8, and apply it multiple times by spraying or rolling, with an interval greater than or equal to 24 hours.

[0014] An incense burner comprises a furnace body obtained according to a clay furnace body processing technology; or a furnace body and one or more of a furnace cover, a base, and an inner container.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The earthen furnace body processing technology of the present invention introduces earthen materials and processing technology methods that meet the characteristics of earthen materials into the incense burner handicraft industry, expands new product areas for earthen material science, and ensures the physical properties and chemical stability of the mixed earthen materials by controlling the mass ratio of earthen materials, sand materials, gelling agents and water, so that the furnace body has sufficient strength while maintaining good plasticity and durability. At the same time, it can greatly save the cost of main materials, achieve low energy consumption, pollution-free, environmentally friendly and degradable effects, have clear substantive characteristics, fill the gap in the industry, and compared with the main materials of existing categories of incense burners on the market (taking ordinary copper incense burners with the largest market share as an example), the unit price of materials can be reduced by 99.7%-99.9%, and materials can be obtained locally. Moreover, since the soil used for incense burners requires deep plain soil, it is the preferred type for large-scale foundation leveling and foundation pit excavation in urban construction. This not only meets the recycling of waste soil, but also reduces the cost of incense burner soil materials to 0 or even negative, which is more in line with the requirements of the country's emerging environmental protection technologies. It is a processing method for emerging materials and newly created categories, which not only improves the physical properties and chemical stability of the furnace body, but also enhances the molding effect and durability of the furnace body. At the same time, it meets environmental protection requirements and market demand, and has significant beneficial effects and application prospects.

[0016] The cold processing method of tamping or extrusion molding is adopted in the processing technology. Through layered manual hammering or mechanical extrusion, the mixed soil is laid and compacted layer by layer, which improves the density and strength of the furnace body. High-temperature melting is not used, chemical raw materials are basically not used, and the water consumption is very small. Except for a small amount of electricity, there is no pollution to the air, water source, and land. Dehydration and drying can ensure the drying effect of the furnace body, and the protective agent can prevent the furnace body from moisture, mildew and pollution, which helps to extend the service life of the furnace body.

[0017] Furthermore, the soil material is deep-layer soil with very little organic matter content. Since the surface soil contains a large amount of organic nutrients, rhizomes, and garbage impurities, etc., it will greatly increase the risk of shrinkage and cracking during the production of the finished product. Therefore, the soil material used in the present invention is strictly prohibited from using surface soil, and the soil collection depth is about 80cm-100cm below the surface (depending on the thickness of the humus layer). The excavation method does not damage the agricultural, forestry, animal husbandry, fishery and landscape land, and at the same time, when the product is scrapped, it can still be returned to the field, thereby achieving harmonious coexistence of economy and ecology. At the same time, impurities and moisture in the soil are effectively removed by drying, grinding, screening and high-temperature dry heat treatment, which improves the purity and uniformity of the soil and enhances the molding effect and stability of the furnace body.

[0018] Furthermore, limiting the compaction ratio ensures the uniformity and consistency of the furnace body and helps reduce the occurrence of internal voids and cracks. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention is further described in detail below in conjunction with specific embodiments, which are intended to explain the present invention rather than to limit it.

[0022] The present invention discloses a soil furnace body processing technology, referring to Figure 1 , including the following steps: Step 1: Add water to soil, sand and gelling agent and stir to form a mixed soil material. By mass, the soil material accounts for 10% to 60%, the sand material accounts for 20% to 50%, the gelling agent accounts for 3% to 18%, and the water accounts for 5% to 15%.

[0023] The soil material is the deep soil below the surface humus layer and 80~100cm below the surface; the excavation method is to first dig out the surface humus layer, and then backfill with the humus layer after the soil is taken; the deep soil is successively dried in the sun, ground and screened, and dried at high temperature before mixing. Specifically, the moisture content of the deep soil after drying is less than or equal to 3%; the mesh diameter of the sieve used for grinding and screening is less than or equal to 2mm; during high temperature dry heat disinfection, the temperature is 180~200℃ and the time is 0.5~1h.

[0024] The sand material is coarse sand alone, medium sand alone, or any combination of coarse sand, medium sand and fine sand, or any combination of the three, and the weight of fine sand when combined shall not exceed 50% of the total mass of the sand material; wherein, the particle size of coarse sand is 0.5~3mm, the particle size of medium sand is 0.5~0.35mm, and the particle size of fine sand is 0.35~0.25mm; the weight ratio of coarse sand, medium sand and fine sand is 5:3:2.

[0025] The gelling agent is a cement-based gelling material, lime-based gelling material, gypsum-based gelling material, water glass, resin-based gelling material, protein-based gelling material, sugar-based gelling material, starch-based gelling material or a derivative enhanced product with the above-mentioned types of gelling materials as the main materials.

[0026] The mixing order of the mixed soil material is as follows: when the gelling agent is a dry powder material of cement, lime or gypsum, pour the soil, sand and gelling agent into the mixer together and mix for 1-2 minutes, then add water in small amounts several times under the premise of continuous operation of the mixer, and mix for 3-4 minutes. When the gelling agent is a liquid or protein, sugar or starch gelling material, the soil and sand should be mixed for 1-2 minutes first, then the gelling agent aqueous solution should be added in small amounts several times under the premise of continuous operation of the mixer, and mix for 3-4 minutes.

[0027] Step 2: pour the mixed soil into a mold, and then obtain a rough furnace body by tamping or extrusion molding so that the compaction ratio between the thickness of the loose soil layer and the thickness of the compacted soil layer is greater than or equal to 1.3:1.

[0028] Among them, when the furnace body is formed by layered manual hammering or mechanical extrusion molding, the mixed soil is loosely spread and compacted layer by layer. Specifically, the mixed soil is first poured into the mold and loosely spread at the bottom, with a loose spreading thickness of ≤8cm; the loosely spread mixed soil is then compacted by manual hammering, with a height of ≥1cm after compaction, and a compaction ratio of the loose spreading thickness to the compacted thickness of ≥1.3:1; finally, the loose spreading of the mixed soil and manual compaction are performed alternately until the required height is reached. When loosely spreading the mixed soil, while ensuring that the above conditions are met, the thickness of each layer is adjusted so that the outer surface of the furnace body can show the corresponding layered texture and pattern shape after compaction (such as Figure 5 , 6 as shown).

[0029] The process of forming the furnace body by extrusion molding is as follows: first, the mixed soil material is spread into the mold with a virtual bottom, and the virtual thickness is ≥1cm; then the mixed soil material used to produce patterns and patterns is spread into the mold layer by layer, and the total virtual thickness of each pressing is ≤15cm. Finally, the mixed soil material is squeezed in the mold by mechanical equipment and pressed to the required height.

[0030] Step three, after demoulding, the furnace body is dehydrated and dried and a protective agent is applied to obtain the furnace body.

[0031] Specifically, first remove the formed earth furnace body from the mold; then use a brush to clean the dust on the surface, and repair the surface defects before the furnace body is dry and hardened; then use natural drying or drying to dehydrate and dry. When drying naturally, the time is greater than or equal to 3 days; when drying, the temperature is greater than 200℃, and the drying time is based on the weight of the furnace body no longer decreasing. Finally, apply a protective agent on the furnace body. The protective agent is an environmentally friendly wall protective agent, interface agent and protein wall protective agent emulsion. You can choose a colorless, odorless, non-volatile, and non-toxic environmentally friendly wall protective agent, interface agent and protein wall protective agent emulsion. When applying, mix the protective agent with water in a ratio of 1:2~1:8, and use spraying or rolling to apply multiple times, with an interval of greater than or equal to 24 hours.
