[0019] In order to deepen the understanding of the present utility model, the following will further elaborate on the present utility model in combination with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.

[0020] According to Figures 1-4 As shown, this embodiment provides a regulation device for silicate hydrolysis, including a mounting seat 1. The cross-section of the mounting seat 1 is in a U shape. An electrical control cabinet 2 is installed on the mounting seat 1. The electrical control cabinet 2 is the general control terminal (microcomputer) of this device, which has the functions of power supply and control. That is, the electronic components of this device are electrically connected to the electrical control cabinet 2 and are controlled by it. Correspondingly, when this device is working, the electrical control cabinet 2 is connected to an external power supply device.

[0021] A reactor 3 is arranged inside the mounting seat 1, and the reactor 3 is connected to the mounting seat 1 through a bracket. Temperature sensors 15 are installed on both sides of the reactor 3, and the temperature sensors 15 are electrically connected to the electrical control cabinet 2. The temperature sensors 15 are used to sense the temperature inside the reactor 3 and transmit the sensed signals into the electrical control cabinet 2. Feed sealing ports 16 and discharge sealing ports 17 are also installed on the reactor 3, which are used for the entry and discharge of materials during the silicate hydrolysis process. Valves are provided on both the feed sealing port 16 and the discharge sealing port 17.

[0022] A stirring assembly is installed inside the reactor 3, and the stirring assembly is driven by a motor 4. As Figure 1As shown in the figure, the stirring assembly includes a load-bearing shaft 8. The load-bearing shaft 8 is connected to the reaction kettle 3 through bearings. A stirring frame 9 is installed at the upper end of the load-bearing shaft 8. The lower end of the load-bearing shaft 8 is connected to the output end of the motor 4, and the motor 4 is connected to the reaction kettle 3 through a bracket. A fixing column 10 is installed on the stirring frame 9, and there are several groups of fixing columns 10. In this embodiment, there are four groups of fixing columns 10 evenly arranged, and a stirring plate 11 is installed on the fixing column 10. During operation, the output power and startup of the motor 4 are controlled by the electrical control cabinet 2. Thus, during the hydrolysis of silicate ester, it is convenient for the staff to adjust the output power of the motor 4, so as to adjust the rate at which the stirring assembly stirs the material. Correspondingly, when the motor 4 is working, it drives the stirring frame 9 to rotate through the load-bearing shaft 8, so that the stirring plate 11 stirs the material.

[0023] A heating assembly is installed on the outer side of the reaction kettle 3, and the heating assembly is connected to the mounting seat 1 through a bracket, as Figure 3 shown. The heating assembly includes a left heat insulation housing 12 and a right heat insulation housing 13. The left heat insulation housing 12 and the right heat insulation housing 13 are connected by bolts, and the left heat insulation housing 12 is connected to the mounting seat 1 through a bracket. In this device, the left heat insulation housing 12 and the right heat insulation housing 13 adopt a split design, which is convenient for disassembly and installation. At the same time, electric heating plates 14 are installed on the inner sides of the left heat insulation housing 12 and the right heat insulation housing 13, and electric heating wires are distributed in the electric heating plates 14. There are several groups of electric heating wires. When the heating assembly is installed, the inner side of the electric heating plate 14 fits the surface of the reaction kettle 3, and at this time the electric heating plate 14 is located inside the left heat insulation housing 12 and the right heat insulation housing 13, that is, the left heat insulation housing 12 and the right heat insulation housing 13 play a certain protective role to prevent the staff from accidentally touching. Correspondingly, during operation, the electric heating plate 14 is started, and by changing its power, the effect of controlling the reaction temperature in the reaction kettle 3 is achieved.

[0024] Above the mounting seat 1, there are several dosing cylinders 5 installed. In this embodiment, there are two dosing cylinders 5. A delivery pump 6 is installed at the lower end of the dosing cylinder 5. The input end of the delivery pump 6 is connected to the inside of the dosing cylinder 5 through a pipeline. In this device, the dosing cylinder 5 is used to pre-add different liquid materials, and the liquid materials are the materials related to the hydrolysis process of silicate ester. Correspondingly, an electric flow valve 7 is installed at the upper end of the reaction kettle 3, and the number of electric flow valves 7 corresponds to that of the dosing cylinders 5. The electric flow valve 7 is connected to the delivery pump 6 through a pipeline, and the output end of the electric flow valve 7 is located inside the reaction kettle 3. Thus, during operation, by controlling parameters such as the opening and closing and flow rate of the corresponding electric flow valve 7, the dropping sequence and dropping rate of the material can be regulated.

[0025] Correspondingly, the batching cylinder 5 is connected to the mounting base 1 through a bracket, and a cylinder cover 20 is installed at the upper end of the batching cylinder 5. The cylinder cover 20 is connected to the batching cylinder 5 by threads. The threaded connection method facilitates the connection and disassembly of the cylinder cover 20 and the batching cylinder 5.

[0026] Furthermore, a box cover 18 is installed at the upper end of the reaction kettle 3. An extension part 19 is provided at the lower end of the box cover 18, and the extension part 19 is connected to the reaction kettle 3 by threads. A sealing ring is provided between the box cover 18 and the reaction kettle 3. In this device, the reaction kettle 3 is designed to be openable. However, before opening, the pipeline between the electric flow valve 7 and the delivery pump 6 needs to be removed first, and then it can be opened, which facilitates the subsequent cleaning of the inside of the reaction kettle 3.
