Description

Technical Field

[0001] This utility model relates to the field of anti-corrosion and heat-insulating materials, and more specifically, to a mixing and proportioning device for anti-corrosion and heat-insulating materials. Background Technology

[0002] Corrosion-resistant and thermal insulation materials are a type of composite material that combines the functions of preventing corrosion of the substrate material and reducing heat transfer. They are widely used in petrochemical, building pipeline, and thermal engineering fields. They are composed of anti-corrosion coating materials such as epoxy resin, polyvinyl chloride, and fluorocarbon coatings, as well as functional additives such as flame retardants, anti-aging agents, and adhesives. These materials extend the service life of equipment or pipelines and reduce energy consumption by blocking the contact between air, moisture, and the substrate, while utilizing the characteristics of low thermal conductivity to reduce heat exchange. They are indispensable key materials in industrial production and infrastructure construction.

[0003] In the production process of anti-corrosion and thermal insulation materials, the uniform mixing of various raw materials is the core link to ensure product performance. The ratio of different raw materials directly affects the key indicators such as anti-corrosion effect, thermal insulation performance, and mechanical strength of the material. At present, the mixing equipment used usually requires manual mixing and injection during the material injection stage. This method is greatly affected by factors such as human condition and operating habits, and is prone to mixing deviation. On the other hand, even if the metering equipment is used to pre-weigh, the raw materials still need to be weighed in the metering device first, and then manually transferred to the mixing equipment, which increases the production steps, prolongs the processing cycle, and can also affect the mixing accuracy due to material residue, secondary pollution and other problems.

[0004] Therefore, a mixing and proportioning device for anti-corrosion and heat-insulating materials is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a mixing and proportioning device for anti-corrosion and heat-insulating materials to solve the problems mentioned in the background art.

Furthermore, through the cooperation of the volumetric pump 8, the conveying pipe 16, the extraction pipe 15 and the injection pipe 10, the raw materials can be transported in a fully enclosed process during injection, eliminating the manual transfer step after weighing by traditional metering equipment and avoiding material residue and secondary pollution during the transfer process. Example

[0026] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail:

The setting of multiple solenoid valves makes the switching of the injection, circulation, and discharge processes of the equipment more flexible and improves the flexibility of operation.

[0028] like Figures 1-5 As shown, in a preferred embodiment, each storage assembly 2 includes a raw material storage tank 201. The bottom end of each raw material storage tank 201 is fixedly connected to a storage outlet pipe 202. The bottom end of each storage outlet pipe 202 is fixedly connected to the upper surface of the conveying pipe 16. An electromagnetic metering valve 203 is fixedly connected to the outer surface of each storage outlet pipe 202. An injection pipe 205 is fixedly connected to the upper surface of each raw material storage tank 201. A sealing plug plate 206 is threadedly connected to the inner ring of each injection pipe 205. Each raw material... The upper surface of the material storage tank 201 is fixedly connected with a breather valve 204. Furthermore, the material storage tank 201 enables the classified storage of different raw materials. The material outlet pipe 202 can transport the raw materials to the conveying pipe 16. The electromagnetic metering valve 203 can control the outflow of each raw material to ensure the accuracy of the proportioning. The injection pipe 205 is used to replenish the raw material storage tank 201. The sealing plug 206 can prevent the raw materials from getting damp or contaminated. The breather valve 204 balances the air pressure inside and outside the material storage tank 201 to ensure that the raw materials can flow out smoothly.

[0029] like Figures 1-5 As shown, in a preferred embodiment, two bearings 18 are fixedly embedded in the inner wall of the mixing drum 1. The inner rings of the two bearings 18 are fixedly connected to the outer surfaces of both ends of the mixing rod 5. Two spiral blades 6 are fixedly connected to the outer surface of the mixing rod 5. A material injection hood 19 is fixedly connected to the upper surface of the mixing drum 1. Two support bases 20 are fixedly connected to the bottom surface of the mixing drum 1. Two heat dissipation holes 21 are opened on the outer surface of the drive cover 3. Two support frames 17 are fixedly connected to the bottom surface of each material storage component 2. Furthermore, the bearings 18 reduce the friction when the mixing rod 5 rotates, and the cooperation between the spiral blades 6 and the mixing blades 7 enhances the uniformity of mixing.

[0030] The working process of this utility model is as follows:

[0031] When using the mixing equipment for the anti-corrosion and heat insulation material, different raw materials are first stored in the raw material storage tank 201. When it is necessary to mix the materials, the flow rate of each raw material can be adjusted by controlling the electromagnetic metering valve 203 on the outer surface of each storage outlet pipe 202. After the raw materials flow into the conveying pipe 16 through the storage outlet pipe 202, the injection solenoid valve 14 is opened and the volumetric pump 8 is started. The mixed raw materials are drawn in through the extraction pipe 15. At this time, the injection solenoid valve 11 is opened and the raw materials enter the mixing drum 1 through the injection pipe 10.

[0032] After the raw materials are injected into the mixing drum 1, the geared motor 4 drives the mixing blades 7 and the spiral blades 6 to rotate via the driving rod 5. The two sets of mixing blades 7 perform radial mixing of the raw materials, while the spiral blades 6 push the raw materials to circulate axially. If it is necessary to further enhance the mixing effect, the injection solenoid valve 14 can be closed and the discharge solenoid valve 22 can be opened. The positive displacement pump 8 re-extracts the raw materials in the mixing drum 1 through the circulation extraction pipe 9 and injects them again through the injection pipe 10 to form a circulating mixing circuit. After the mixing is completed, the injection solenoid valve 14 and the injection solenoid valve 11 are closed and the discharge solenoid valve 12 is opened, so that the mixed material can be discharged through the discharge pipe 13. This is the working process and working principle of the device.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
