Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of processing calcium silicate thermal insulation products, and in particular relates to a water filtering structure for producing calcium silicate thermal insulation products. Background Art
[0002] Calcium silicate insulation products, as environmentally friendly hard inorganic thermal insulation materials with high strength and low thermal conductivity, have always been favored by the market and have been widely used in petrochemical, electric power, heating network, shipbuilding and other fields.
[0003] There are two main processes for the production of calcium silicate insulation products, the static method and the dynamic method, and both processes involve the process of slurry pressing and filtering. Because the solid particles of the slurry are small, especially the slurry particles produced by the dynamic method are generally tens of microns, it is easy to run during the filter pressing and forming process. In order to form a solid block with a certain regular shape and suitable strength properties through filter pressing, it is generally necessary to change the forming properties of the slurry by adding wood or cotton fibers or use a filter cloth type filter screen for filter pressing. Adding a certain amount of wood or cotton fibers to the slurry to improve the drainage and forming ability of the slurry will directly increase the production cost of the product. At the same time, because the filter screen with larger holes is used as the interception valve of the slurry, more materials are lost during the pressing process, which increases the cost of collecting and treating the water from the filter press in the later stage. The filter cloth type filter screen is easy to wear during use and has a short service life. In addition, the filter cloth type filter screen has a large elasticity and is easy to wrinkle, which affects the surface quality of the product and makes it difficult to demold the product. Summary of the invention
[0004] The utility model aims to provide a technical solution of a water filter structure for the production of calcium silicate insulation products in view of the deficiencies in the prior art. The structural design is ingenious and reasonable, and the practicability is strong. The water filter structure has good water filtering performance, and the slurry is not easy to run during the filter pressing process. The water filter structure is easy to demould and clean, and has a long service life, which greatly improves the production efficiency. At the same time, the use of the water filter structure can reduce the amount of wood and cotton fibers in the slurry, and there is even no need to add wood and cotton fibers to the slurry, which effectively reduces the production cost and simplifies the production process.
[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0006] A water filter structure for producing calcium silicate insulation products comprises a bottom plate layer, a wire mesh layer and a steel plate layer, wherein the bottom plate layer is provided with water permeable holes, the wire mesh layer is arranged between the steel plate layer and the bottom plate layer, the steel plate layer is provided with water seepage holes, and the steel plate layer is in contact with the product; the structural design is ingenious and reasonable, and the practicability is strong; the water filter structure has good water filtering performance, and the slurry is not easy to run during the filter pressing process; the water filter structure is easy to demould and clean, and has a long service life, which greatly improves the production efficiency; at the same time, the use of the water filter structure can reduce the amount of wood and cotton fibers in the slurry, and even does not need to add wood and cotton fibers to the slurry, effectively reducing the production cost and simplifying the production process.
[0007] Furthermore, water guide grooves are arranged on the bottom plate layer in a criss-cross manner. The structural design is ingenious and reasonable. The water guide grooves provide a circulation channel for the filtered water flow, so that the filtered water can pass through the water filtering structure efficiently and orderly, and guide the filtered water to be discharged quickly, which effectively improves the filtration efficiency. The water guide grooves are criss-crossed and reasonably positioned. The criss-crossing arrangement can provide a smoother and more efficient path for the water flow, so that the filtered water can pass through the water filtering structure faster, which is more conducive to improving the filtration speed. The depth and thickness of the water guide grooves can be designed to be about one tenth of the thickness of the bottom plate layer.
[0008] Furthermore, the thickness of the bottom plate layer is 15 to 30 mm, the thickness of the bottom plate layer is greater than 10 mm, and is preferably set between 15 and 30 mm, to ensure the structural strength of the bottom plate layer, provide firm and stable support for the entire water filtration structure through the bottom plate layer, and facilitate the coordinated installation and use between the water filtration structure and other components.
[0009] Furthermore, the surface of the steel plate layer is coated with a Teflon layer, which is cleverly and reasonably designed. The Teflon layer has extremely strong non-stickiness, which ensures smooth demoulding of the product and improves the product yield. It can effectively prevent slurry adhesion, reduce the risk of clogging of the water filtration structure, and improve the filtration efficiency of the water filtration structure. It is also convenient for subsequent cleaning and maintenance of the water filtration structure. Teflon has good alkali and heat resistance. The integrity of the Teflon layer is guaranteed after multiple pressure filtrations of the water filtration structure, which can extend the service life of the water filtration structure.
[0010] Furthermore, the thickness of the steel plate layer is 0.8-1 mm, the aperture of the seepage hole is 0.8-1.5 mm, the size design is reasonable, and the aperture size of the seepage hole is preferably 0.8-1.5 mm. While ensuring the water seepage effect of the steel plate layer, the seepage of slurry is avoided as much as possible. The distribution position and number of the seepage holes on the steel plate layer are not limited and can be adjusted according to actual water filtration requirements.
[0011] Furthermore, the wire mesh layer is a stainless steel wire mesh layer with an ingenious and reasonable design. The stainless steel wire mesh layer has excellent corrosion resistance and wear resistance. The use of the stainless steel wire mesh layer can ensure the filtering performance of the wire mesh layer and extend its service life. The stainless steel wire mesh layer has a precise mesh size, and a suitable mesh size can be selected according to the particle size of the slurry to achieve a fine filtering effect.
[0012] Furthermore, the stainless steel wire mesh layer adopts 304 or 316 stainless steel wire mesh layer. The stainless steel wire mesh layer made of 304 or 316 has excellent corrosion resistance, high structural strength and good stability.
[0013] Furthermore, the mesh size of the wire mesh layer is 100-300 meshes, and the size design is reasonable. The mesh size is limited to 100-300 meshes according to the particle size of the slurry, which can effectively prevent the micron-level slurry from running, ensuring the accuracy of feeding and the quality of filtered water reuse after filtration.
[0014] Furthermore, the bottom plate layer, wire mesh layer and steel plate layer are connected by penetrating laser welding. The bottom plate layer, wire mesh layer and steel plate layer are welded and fixed by penetrating laser welding, which effectively improves the overall stability and strength of the water filtration structure and can effectively prevent the slippage of the second wire mesh layer. The laser welding welds are smooth and beautiful, which can ensure the quality of the water filtration structure after welding and will not affect the filtration effect of the water filtration structure on the slurry.
[0015] Furthermore, the edge of the steel plate layer is welding area one, and the remaining part is welding area two. Welds are arranged along the edge of the steel plate layer in welding area one, and at least two horizontal rows of welds are arranged along the length direction of the steel plate layer in welding area two. Adjacent horizontal rows of welds are staggered. Welds are welded at the edge and middle of the steel plate layer, which effectively ensures the welding firmness and reliability among the bottom plate layer, the wire mesh layer and the steel plate layer. There are multiple rows of welds in the middle part, and adjacent rows of welds are staggered with each other, which further improves the welding quality, so that the wire mesh layer of the second layer will not slip or slide, thereby ensuring the quality of the water filtration structure and extending its service life.

The water filtering structure has good water filtering performance and the slurry is not easy to escape during the filtration process, which ensures the accuracy of feeding. The clear filtered water makes it relatively simple to reuse the filtered water. At the same time, the water filtering structure is easy to demould and clean, has a long service life, and greatly improves the production efficiency. In addition, the use of the water filtering structure can reduce the amount of wood and cotton fibers in the slurry, and there is even no need to add wood and cotton fibers to the slurry, which effectively reduces the production cost and simplifies the production process.
