Description

Technical Field

[0001] The utility model relates to the technical field of material mixing metering, in particular to a metering tank for mixing materials in the production of modified silane sealant. Background Technique

[0002] Modified silane sealant is a special sealing glue. It uses silane as the polymer base and adds a variety of materials to change its structure, making it more suitable for applications in various occasions; its physical properties include high solid content, good low-temperature support, low volatility, and excellent stretchability. It has excellent weather resistance, heat resistance, cold resistance, and dynamic durability; low viscosity, long pot life, high early strength, easy to construct and decorate. However, during the production of mixed materials, due to uneven local mixing, the local moisture content is too high, which easily leads to the phenomenon that the local part of the later product thickens and cannot be used. Therefore, it is necessary to perform mixing operations during the production process.

[0003] During the production of modified silane sealant, the metering of the mixed materials is a crucial link. The accurate metering of the mixed materials is crucial for ensuring the quality and performance of the product. However, in the actual use process, when the mixing tank controls the viscous mixing of materials during the mixing process, its temperature holding ability is relatively insufficient. It is easy to cause a high degree of change in the viscosity of the rubber material due to temperature changes, resulting in a large loss of raw materials. Moreover, the stable value of weight metering is insufficient, and it is easy to have tank body residue. The accuracy of the raw material quantity diversion is insufficient, and it is inconvenient to clean later. Therefore, we propose a metering tank for mixing materials in the production of modified silane sealant to solve the above problems. Summary of the Utility Model

[0047] It should be noted that the devices in this application are all common devices in the market, which can be selected according to needs during specific use. Moreover, the circuit connection relationships of the devices all belong to simple series and parallel connection circuits, and there is no innovation point in terms of circuit connection. Those skilled in the art can easily implement it, which belongs to the prior art and will not be elaborated further.

[0048] Working principle: By providing a heat preservation inner tank 2 inside the outer tank 1 of the metering tank, it plays a role in heat insulation, so that when the colloid raw material is mixed for production consistency, the temperature loss is not likely to occur, so that the consistency of the rubber material is always controllable, the raw material is not easily wasted, and the waste caused by raw material loss is reduced;

[0049] A driving stirring member 8 and an auxiliary cleaning plate 11 are provided inside the heat preservation inner tank 2. By operating the driving motor 7, the driving stirring member 8 can be controlled to mix the raw materials and control the consistency. The auxiliary cleaning plate 11 can clean and scrape the raw materials remaining on the inner wall of the heat preservation inner tank 2 to prevent raw material residues. The raw materials are directly discharged from the material outlet pipe 5. The flow control valve 10 can visually display and control the quantity of the dosage, and the diversion pump 9 can play a role in pressurizing and diverting the raw materials, and the discharge amount of the raw materials is relatively accurate and stable;

[0050] A weight measuring device 3 is provided at the bottom of the outer tank 1 of the metering tank, which can visually display the weight of the raw materials in the tank. Both the import amount and the discharge amount can be stably measured. Cooperating with the auxiliary cleaning plate 11, the raw materials remaining in the tank can be stably scraped off, and material residues are not likely to occur. The discharge amount is relatively accurate and thorough, and the self-cleaning ability inside the tank is good, so that the heat preservation effect of the device is good, the temperature loss is not likely to occur, the rubber material can be stably and highly quality mixed, and the tank has the ability to scrape and clean, and the discharging and metering are relatively accurate, solving the problems that the existing metering tank is prone to changes in consistency due to temperature loss during mixing, and the discharging amount is not accurate enough and residues are likely to occur.

[0051] Example 2: Please refer to Figure 5 , including DINP storage tank, 2000D polyether storage tank, stirring metering tank one, mixture metering tank one, diaphragm pump, powder weighing and metering bins one and two, powder mixing and discharging hopper, stirring metering tank two, mixture metering tank two, first-stage screw, condenser, second-stage screw, base material mixing intermediate tank, base material storage and pressure tank, static mixer, static filling.

[0052] Specifically, the raw materials are fed into the storage tank and the metering bin. The liquid materials enter the mixed material metering tank after passing through the stirring and metering tank, and the powder materials enter the powder mixing and discharging hopper through the metering bin. The liquid materials and the powder materials enter the screw machine for mixing, and then enter the condenser. After cooling, they are mixed with liquid materials in the second-stage screw, and then enter the base material mixing intermediate tank. When the tank is full, it is directly pressed into the storage tank, and then passes through the static mixer and the filling machine to produce the finished product. The whole process uses vacuum-sealed pipelines, with very little raw material loss, stable product quality, and high automation level.

[0053] The production process is improved by adding a base material mixing intermediate tank, which can remix the base materials with uneven local mixing and incomplete water removal to meet the requirement of complete water removal. In this way, the phenomenon that the product is locally solidified and unusable due to excessive local moisture will no longer occur.

[0054] The traditional production of modified silane sealant has a low degree of automation. Due to the low temperature resistance of its resin raw materials, a semi-automatic production process is mostly used. In some cases where automated production is adopted, due to uneven local mixing resulting in excessive local moisture, there is a tendency for the product to locally thicken and become unusable later. In semi-automatic production, there is a large raw material loss and high human resource cost, consuming a large amount of resources. To solve the problem of local thickening of the product, the base materials with uneven local mixing are remixed to meet the production control requirements.

[0055] Working principle: First, the liquid materials DINP and 2000D are respectively pumped into the storage tank and then proportionally pumped into the first stirring and metering tank. After being stirred well, they are pumped into the first mixed material metering tank. At the same time, nano-calcium and heavy calcium are respectively added to the first and second powder weighing and metering bins. The two bins discharge the powder materials proportionally into the powder mixing and discharging hopper. The first mixed material metering tank and the mixing and discharging hopper simultaneously discharge materials proportionally by their respective diaphragm pumps into the first-stage screw machine for high-temperature vacuum dehydration and mixing, and then enter the condenser for cooling, and then enter the second-stage screw machine.

[0056] The resin and the water remover 171 are pumped into the second stirring and metering tank. After being stirred evenly, they are pumped into the second mixed material metering tank, and at the same time enter the second-stage screw together with the materials in the condenser. After mixing, they enter the base material mixing intermediate tank, where they are stirred. When the tank is full, it is automatically pressed into the base material storage tank, and then pressed into the static mixer by the base material storage tank. Pigments and the remaining additives are added in the static mixer. After static mixing, the finished product is packaged by the filling machine.

[0057] It should be noted that in this text, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variation thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the said element.

[0058] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
