Description

Technical Field

[0001] The present application relates to a rolling glue making machine, a glue making system and a glue making method. Background Art

[0002] In industrial production such as chemical industry, it is often encountered that one or several solid powders are mixed, kneaded, humidified and other processes with one or several liquids and colloids, and these processes are basically completed by intermittent stirring. For example, in the colloid preparation process of cracking catalyst, the raw materials (such as water, aluminum sol, molecular sieve slurry) and powder raw materials (kaolin, pseudo-boehmite) for preparing catalyst colloid are respectively calculated and put into the colloid kettle in proportion, stirred for a certain period of time, and then a certain amount of acid is added as required for stirring and acidification to prepare the colloid before spray granulation. This intermittent production process has the disadvantages of poor continuity, small processing capacity, large manual feeding error, high labor intensity, and serious on-site dust. More importantly, it cannot adapt to the large-scale continuous and automated production process of modern factories. Therefore, it is necessary to develop a machine for continuously and efficiently preparing powders, colloids and liquids into colloids, realize the process of continuous mixing of solid powders and liquids and colloids, and efficient and rapid preparation of colloids, so as to realize the continuous and automated production process of this industry.

[0003] Kaolin and pseudo-boehmite are powder raw materials for cracking catalysts, which contain solid particle impurities such as blocky stones, iron blocks, wooden sticks, woven bags, and cloth strips. After removing these impurities, the particle size of these two raw materials is very fine, not exceeding tens of microns. Due to the presence of these solid impurities, the sorting process will inevitably increase, which will increase energy consumption, dust and other phenomena, and cause secondary dust pollution again; if the continuous preparation process of catalyst colloid is directly realized by crushing and grinding machinery, there will inevitably be the danger of jamming the machine or even damaging the machine. Therefore, it is necessary to develop a colloid rapid colloid making machine for cracking catalysts that can resist the solid impurities contained in the raw materials and withstand the impact of solid impurities.

[0004] Patent CN1552801A describes a method for preparing a cracking catalyst using a silica sol binder. The method involved in the patent is to prepare several required colloids in a colloid-forming tank in advance, such as one colloid of silica sol and one colloid of molecular sieve, and one colloid of clay and pseudo-boehmite, and then mix the three colloids in a fast stirring mixing kettle to obtain the colloid before the catalyst is dried. It mentions that silica sol is prepared according to the method of patent US3957689, but in fact, only the preparation of silica sol and the mixing of several colloids are partially implemented continuously in the fast stirring mixing kettle, and the entire catalyst continuous preparation process is not realized.

[0005] Patents CN1098130A "A cracking catalyst and its preparation method" and CN1436835A "A catalytic cracking catalyst and its preparation method" all describe the preparation formula of cracking catalysts, but do not mention the continuous gelling process.

[0006] Patents CN1580195A “Method for preparing cracking catalyst” and CN1579725A “Method for preparing kaolin colloid” describe a method for continuous preparation of cracking catalyst and kaolin colloid, which are limited to the preparation method of kaolin colloid and pseudo-boehmite colloid, and do not involve the continuous mixing process of solid powder (kaolin, pseudo-boehmite) with liquid (water) and colloid (molecular sieve slurry, aluminum sol), and there is no description of specific equipment. Therefore, it is impossible to truly implement the continuous preparation process of catalyst colloid.

[0007] Patents CN110652914A, CN109718725A, and CN109718832A describe a continuous preparation machine and method for a cracking catalyst colloid. This technology uses a process in which a powder raw material is introduced from the center of a rubber making machine, a liquid raw material and a colloid raw material are introduced from the outer wall tube outside the center tube, or an outer sleeve annular space into the rubber making machine, and the catalyst colloid is quickly prepared between the mixing teeth of the rotating disk and the fixed disk in the rubber making machine. This technology can realize the process of efficiently and quickly preparing a catalyst colloid for a powder raw material without solid impurities (such as blocky stones, iron blocks, wooden sticks, woven bags, cloth strips, etc.). However, kaolin and pseudo-boehmite powder raw materials often contain solid impurities such as blocky stones, iron blocks, wooden sticks, woven bags, cloth strips, etc., and a process of removing impurities and screening is required, otherwise the rubber making machine will be stuck, and in severe cases, the mixing teeth that are intermeshed with each other will be damaged, causing damage to the rubber making machine.

[0008] In summary, the existing technology does not yet involve a cracking catalyst colloid rapid colloid making machine that can resist the impact of raw material solids. Summary of the invention
