Description

Technical Field

[0001] This utility model relates to the field of powder coating processing technology, and more specifically, to an environmentally friendly powder coating multi-raw material mixing device. Background Technology

[0002] Powder coating is a solvent-free solid powder coating that exists in the form of fine powder. Its main components include solid resin, pigments, fillers, and additives. Unlike traditional solvent-based and water-based coatings, powder coating does not release volatile organic compounds (VOCs) during production and application. It has advantages such as solvent-free pollution, low energy consumption, and environmental friendliness. In the production process of powder coating, mixing equipment is required to mix the coating raw materials.

[0003] Based on the above, the inventors have discovered that existing mixing devices mainly use stirring rollers for mixing. However, the flowability of powder coatings is poor compared to solvent-based coatings. Therefore, simply using stirring rollers for mixing results in poor mixing effects. In view of this, the inventors have researched and improved the existing structure to provide an environmentally friendly multi-raw material mixing device for powder coatings, aiming to achieve a more practical purpose. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an environmentally friendly multi-raw material mixing device for powder coatings. This solution uses an air-blowing and floating method combined with stirring to mix the raw materials while they are floating, thereby improving the mixing effect of the powder coating raw materials. Furthermore, a guide component is provided to support the movement of the pressure plate, and a filter component that is easy to disassemble and install can prevent powder from entering the airflow circulation component, reduce clogging problems, and ensure normal airflow circulation.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] An environmentally friendly powder coating multi-raw material mixing device includes a mixing tank. A drive motor is fixedly connected to the center of the top surface of the mixing tank, and an air pump is fixedly connected to one side of the top surface of the mixing tank. An air intake groove and an air inlet groove are respectively opened at both ends of the interior of the mixing tank. A return pipe and an outlet pipe are fixedly connected to both ends of the air pump, and a filter mechanism is provided at the connection between the air pump and the return pipe. A set of stirring rollers is fixedly connected to the output end of the drive motor, and a cleaning plate is fixedly connected to both ends of the stirring rollers.

[0009] The filtration mechanism includes a filter cylinder, with extension sleeves extending through both ends of the filter cylinder. Each end of the extension sleeve is fixedly connected to a snap-fit ​​connector and a threaded ring, respectively.

[0010] Furthermore, a filter screen is fixedly connected to both the bottom surface of the air intake groove and the top surface of the air inlet groove.

[0011] Furthermore, the cleaning plate at the top of the stirring roller is attached to the filter screen at the bottom of the air intake groove, and the cleaning plate at the bottom of the stirring roller is attached to the filter screen at the top of the air intake groove.

[0012] Furthermore, the return pipe is connected to the intake slot, and the outlet pipe is connected to the intake slot.

[0013] Furthermore, the mixing tank is fixedly connected to an inlet and an outlet valve on one side of the upper end and at the bottom, respectively.

[0014] Furthermore, a filter element is fixedly connected to the center of the filter cylinder, and a threaded ring is threadedly connected to the filter cylinder.

[0015] Furthermore, the two snap-fit ​​connectors are respectively snap-fitted to the input end of the air pump and the top end of the return pipe.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] (1) This solution uses a stirring roller to mix and stir the powder raw materials. At the same time, the air outlet pipe and the air inlet groove discharge the air to blow the powder raw materials to disperse. Then, the air intake groove and the return pipe guide the air flow back to achieve air circulation. When the stirring roller rotates, it drives the cleaning plate to clean the powder on the surface of the filter screen. Compared with the existing technology, the blowing and floating method is set to mix and stir the raw materials in a floating state, which improves the mixing effect of the raw materials of the powder coating.

[0019] (2) By setting up a filter mechanism, the filter cylinder filters the return air, reducing the clogging problem. After the mixing work is completed, the extension sleeve is rotated to drive the threaded ring to rotate inside the filter cylinder, thereby adjusting the position of the snap-fit ​​connector. This allows the two snap-fit ​​connectors to separate from the input end of the air pump and the top of the return pipe, respectively, so that the filter cylinder can be removed for replacement. Compared with the existing technology, the filter assembly that is easy to disassemble and assemble can prevent powder from entering the airflow circulation assembly, reduce the clogging problem, and ensure normal airflow circulation.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please see Figure 1-4 An environmentally friendly powder coating multi-raw material mixing device includes a mixing tank 1. A drive motor 2 is fixedly connected to the center of the top surface of the mixing tank 1, and an air pump 3 is fixedly connected to one side of the top surface of the mixing tank 1. An air intake groove 6 and an air inlet groove 7 are respectively opened at both ends of the interior of the mixing tank 1. A return pipe 9 and an air outlet pipe 10 are fixedly connected to both ends of the air pump 3, and a filter mechanism 11 is provided at the connection between the air pump 3 and the return pipe 9. A set of stirring rollers 12 is fixedly connected to the output end of the drive motor 2, and a cleaning plate 13 is fixedly connected to both ends of the stirring rollers 12.

[0028] The filter mechanism 11 includes a filter cylinder 14, with extension sleeves 15 extending through both ends of the filter cylinder 14. The two ends of the extension sleeves 15 are respectively fixedly connected to a snap connector 16 and a threaded ring 17. In order to improve the filtration effect and prevent powder from penetrating into the air pump 3, the filter mechanism 11 is provided.

[0029] See Figure 2 The bottom surface of the air intake trough 6 and the top surface of the air intake trough 7 are both fixedly connected to filter screens 8. The airflow is discharged from the air intake trough 7, which blows the powder raw materials to disperse and improves the mixing effect of the raw materials. Then, the airflow is guided back by the air intake trough 6 and separated into solid and gas through the filter screen 8.

[0030] See Figure 3The cleaning plate 13 at the top of the stirring roller 12 is attached to the filter screen 8 on the bottom surface of the air intake groove 6, and the cleaning plate 13 at the bottom of the stirring roller 12 is attached to the filter screen 8 on the top surface of the air intake groove 7. The drive motor 2 is started to drive the stirring roller 12 to rotate, mix and stir the powder raw materials, and at the same time drive the cleaning plate 13 to clean the powder on the surface of the filter screen 8 to ensure smooth airflow.

[0031] See Figure 2 The return pipe 9 is connected to the intake slot 6, and the exhaust pipe 10 is connected to the intake slot 7. When the air pump 3 is started, the exhaust pipe 10 works in conjunction with the return pipe 9 to achieve airflow circulation.

[0032] See Figure 1 The mixing tank 1 is fixedly connected to a feed inlet 4 on one side and a discharge valve 5 on the bottom. The raw materials are fed into the mixing tank 1 through the feed inlet 4 and discharged by the discharge valve 5.

[0033] See Figure 4 The filter element is fixedly connected in the center of the filter cylinder 14, and the threaded ring 17 is threadedly connected to the filter cylinder 14. During the airflow circulation process, the filter cylinder 14 filters the returning air.

[0034] See Figure 4 The two snap-fit ​​connectors 16 are respectively snap-fitted to the input end of the air pump 3 and the top end of the return pipe 9. Rotating the extension sleeve 15 causes the threaded ring 17 to rotate inside the filter cartridge 14, thereby adjusting the position of the snap-fit ​​connectors 16.

[0035] In use: The raw materials are fed into the mixing tank 1 through the feed inlet 4. The drive motor 2 is started to drive the stirring roller 12 to rotate and mix the powder raw materials. At the same time, the air pump 3 is started, and the air outlet pipe 10 and the air inlet groove 7 discharge airflow to blow the powder raw materials and improve the mixing effect. Then, the air intake groove 6 and the return pipe 9 guide the airflow back to achieve airflow circulation. Solid-gas separation is performed by passing through the filter screen 8. At the same time, when the stirring roller 12 rotates, it drives the cleaning plate 13 to clean the powder on the surface of the filter screen 8 to ensure smooth airflow and improve the floating effect of the raw materials. During the airflow circulation process, the filter cylinder 14 filters the return air to prevent powder from entering the airflow circulation component and reduce clogging. After the mixing work is completed, the extension sleeve 15 is rotated to drive the threaded ring 17 to rotate inside the filter cylinder 14, thereby adjusting the position of the clamping connector 16 so that the two clamping connectors 16 are separated from the input end of the air pump 3 and the top end of the return pipe 9, respectively. The filter cylinder 14 can then be removed for replacement.
