Description

Technical Field

[0001] This utility model relates to the field of coating preparation equipment technology, and in particular to a mixing device for coating preparation. Background Technology

[0002] As a key material for ensuring the performance and lifespan of photovoltaic modules, the performance of photovoltaic coatings directly affects the photovoltaic power generation efficiency and module stability. For example, white fluorine-free photovoltaic coatings need to possess good adhesion, high hardness, scratch resistance, aging resistance, and high light reflectivity. These characteristics depend on the precise proportioning and thorough mixing of various components in the coating. With the development of the industry, simple mechanical mixing equipment has been put into use, such as ordinary mixing tanks, which use motors to drive the mixing blades to achieve raw material mixing. However, such equipment has obvious shortcomings when mixing photovoltaic coatings. The raw materials are metered into the tank and uniformly stirred by the mixing components. This mixing method results in a long mixing cycle for the coating, making it difficult to disperse. The concentrated feeding causes a mismatch between the rhythm and the mixing speed and capacity of the mixing equipment, which can easily lead to uneven mixing of raw materials because the feeding is too fast and the mixing equipment cannot keep up with the mixing. In view of the above reasons, this application proposes a proportioning device for coating preparation with the function of dispersing feeding and uniform mixing. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the background technology by proposing a proportioning device for coating preparation that has the function of dispersing, feeding, and uniform mixing.

[0004] The technical solution of this utility model is based on a proportioning device for coating preparation, including a mixing tank. The top of the mixing tank is provided with multiple feeding hoppers, and the inside of the mixing tank is also provided with a storage cylinder located below the feeding hoppers. The bottom of the storage cylinder is provided with a discharge port.

[0005] Below the storage cylinder is a mixing assembly for coating mixing. The mixing assembly includes a drive motor fixedly installed at the bottom of the storage cylinder. Multiple sets of stirring rods are arranged around the output end of the drive motor. A support rod is arranged above the top layer of stirring rods. One end of the multiple sets of support rods is provided with an abutment rod that contacts the storage cylinder.

[0006] Optionally, each of the feed hoppers is fixedly connected to a discharge pipe at its bottom end, and a control valve is installed on the discharge pipe.

[0007] Optionally, the storage cylinder has multiple feeding chambers, and each feeding port is connected to a baffle plate via a hinge.

[0008] Optionally, the baffle plate is provided in four sets, and the abutment rod and the support rod are each provided in three sets, with the top end of the abutment rod contacting the baffle plate.

[0009] Optionally, a rotating rod is fixedly connected to the output end of the drive motor, and the rotating rod is rotatably connected to the bottom inner wall of the mixing tank.

[0010] Optionally, the stirring rod and the support rod are fixedly connected to the outer ring of the rotating rod.

[0011] Optionally, an inlet pipe penetrating the mixing tank is provided above the storage cylinder, and a discharge pipe is installed through the bottom of one side of the mixing tank.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] This utility model achieves preliminary quantitative metering and weighing by connecting a feeding pipe to the bottom of the feeding hopper, and realizes material dispensing by setting up a material distribution chamber, thereby facilitating the dispersion and feeding of various ingredients.

[0014] Furthermore, the mixing of materials is achieved by setting up a stirring rod. Combined with the setting of a support rod, abutment rod, and baffle plate, the abutment rod intermittently abuts against the baffle plate, blocking the discharge port at the corresponding position, and then discharging into another set of open discharge ports, realizing intermittent discharging of multi-component material chambers, thereby continuously mixing the discharging materials and improving the uniformity of material mixing.

[0015] In summary, this utility model features multi-chamber feeding, dispersed feeding of various materials to avoid material accumulation, intermittent feeding function, good coordination with mixing equipment, and improved optical and mechanical properties of coatings.

[0032] Example

[0033] like Figure 1As shown, the proportioning device for coating preparation proposed in this utility model includes a mixing tank 1. Multiple feeding hoppers 2 are installed on the top of the mixing tank 1. A discharge pipe 21 is fixedly connected to the bottom of each feeding hopper 2. A control valve is installed on the discharge pipe 21 to control the feeding amount. A weighing module is installed on the inner wall of the feeding hopper 2, using a pressure sensor to weigh the material in the corresponding cavity. Specific weighing and control methods are not detailed in this embodiment. A liquid inlet pipe 5 is installed above the storage cylinder 3, penetrating the mixing tank 1. The liquid inlet pipe 5 is used for liquid transportation. A discharge pipe 6 is installed through the bottom of one side of the mixing tank 1. Figure 2 , Figure 3 as well as Figure 4 As shown, the mixing tank 1 is also equipped with a storage cylinder 3 located below the feed hopper 2. The storage cylinder 3 and the mounting ring are connected to the inner wall of the mixing tank 1. The bottom of the storage cylinder 3 is provided with a discharge port 310. The storage cylinder 3 is provided with multiple distribution chambers 31. The number of distribution chambers 31 is the same as the number of feed hoppers 2. Each set of discharge ports 310 is connected to a baffle plate 32 by a hinge. There are four sets of baffle plates 32.

[0034] like Figure 3 As shown, a mixing assembly 4 for mixing coatings is provided below the storage cylinder 3. The mixing assembly 4 includes a drive motor 41 fixedly installed at the bottom of the storage cylinder 3. A rotating rod 42 is fixedly connected to the output end of the drive motor 41. The rotating rod 42 is rotatably connected to the bottom inner wall of the mixing tank 1. Multiple sets of stirring rods 43 are provided on the outer ring of the output end of the drive motor 41. A support rod 44 is provided above the top layer of stirring rods 43. The stirring rods 43 and the support rods 44 are fixedly connected to the outer ring of the rotating rod 42. A contact rod 45 is provided at the top of one end of the multiple sets of support rods 44, which contacts the storage cylinder 3. There are three sets of contact rods 45 and support rods 44. The top end of the contact rod 45 contacts the baffle plate 32.

[0035] In this embodiment, the material in the feed hopper 2 is conveyed to the storage cylinder 3 through the discharge pipe 21. The feed rate is controlled by the control valve on the discharge pipe 21. The rotating rod 42 is rotated by the drive of the mixing assembly 4. At the same time as the rotating rod 42 rotates, the mixing rod 43, the support rod 44, and the abutment rod 45 rotate synchronously. Since there are three sets of abutment rods 45 and four sets of baffle plates 32, one set of baffle plates 32 will open under the action of gravity of the material and the flipping action of the hinge, thus exposing the discharge port 310 for material discharge. As the abutment rod 45 rotates continuously, the baffle plates 32 at different positions open, realizing intermittent material discharge, thereby achieving the effect of dispersed material discharge of different types. Combined with the rotation of the mixing rod 43, thorough mixing is achieved. The material discharge efficiency and mixing efficiency are highly matched, and the mixing effect is excellent.

[0036] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
