Description

Technical Field

[0001] This utility model relates to the field of coating processing technology, specifically to a coating mixing tank cleaning device. Background Technology

[0002] Paint, traditionally known as varnish in China, is a material applied to the surface of an object to be protected or decorated, forming a continuous, firmly adhering film. It is typically a viscous liquid made primarily of resin, oil, or emulsion, with or without pigments and fillers, and with appropriate additives, formulated with organic solvents or water. In the paint production process, multiple components are selected according to actual needs, mixed together, and stirred. Tanks or barrels are generally used as containers during stirring. Because a large number of containers are needed in the production process, they are usually reused to control costs. Therefore, the containers need to be cleaned after each use for future applications. Traditionally, workers use hand brushes and other cleaning tools to scrub the inner walls of the containers. However, this method is inefficient and labor-intensive. Although electric brushes and other cleaning tools are now available, manual operation is still required, making it highly dependent on manual labor. Utility Model Content

Detailed Implementation

[0023] To facilitate understanding of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0024] Reference Figures 1 to 4 This embodiment provides a paint mixing tank cleaning device, including a frame 1, a rotating frame 11 rotatably connected to the frame 1 at one end, a cleaning and sealing cover 2 for sealing the mixing tank disposed on the rotating frame 11, a first conveying mechanism 3 for conveying the mixing tank disposed on the rotating frame 11, a clamping mechanism 4 disposed on the rotating frame 11, a cleaning mechanism 5 disposed on the rotating frame 11, and a rotation drive mechanism 6 disposed on the frame 1 for driving the rotating frame 11 to rotate.

[0025] The cleaning mechanism 5 includes a cleaning bracket 51 mounted on the rotating frame 11, a cleaning drive component 52 mounted on the cleaning bracket 51, a cleaning shaft 53 connected to the output end of the cleaning drive component 52, and a cleaning assembly 54 connected to the cleaning shaft 53. The cleaning drive component 52 is located on one side of the cleaning cover 2, and the first conveying mechanism 3 is located on the other side of the cleaning cover 2. The cleaning shaft 53 extends through the cleaning cover 2 and above the first conveying mechanism 3. During cleaning, the top of the mixing tank contacts the cleaning cover 2, which is equivalent to the cleaning cover 2 being fitted onto the top of the mixing tank, thereby creating a relatively sealed environment in the mixing tank during the cleaning process and preventing water splashing.

[0026] The cleaning assembly 54 includes a plurality of barrel wall brushes 541 disposed on the cleaning shaft 53 for cleaning the inner wall, and a barrel bottom brush 542 disposed at the end of the cleaning shaft 53. The barrel wall brushes 541 need to cover the side walls of the mixing tank axially to ensure thorough cleaning. In this embodiment, three barrel wall brushes 541 are provided. Alternatively, in a specific implementation, the barrel wall brushes 541 can be arranged in a spiral shape with the cleaning shaft 53 as the axis. The barrel bottom brushes 542 are generally L-shaped, matching the shape of the barrel bottom, thus working with the barrel wall brushes 541 to achieve thorough cleaning. At least one barrel bottom brush 542 is provided; in this embodiment, two are provided.

[0027] The cleaning cover 2 has a U-shaped cross-section, and its axis is parallel to the rotating frame 11. A water inlet pipe 21 is connected to the bottom surface of the cleaning cover 2. A drain outlet 22 is located on the side wall of the cleaning cover 2 near the rotating frame 11. An electric valve can also be installed at the drain outlet 22 to control the discharge of wastewater, thus eliminating the need for continuous water supply and achieving water conservation. The water inlet pipe 21 is located at the top of the cleaning cover 2 and is connected to a water pump. During the cleaning process, water is injected into the mixing tank via the water pump. Additionally, a spray nozzle can be connected to the inlet of the water inlet pipe 21 for more even spraying. In practice, a cleaning agent injection pipe can also be installed on the cleaning cover 2 to inject cleaning agent during the cleaning process and ensure cleaning effectiveness. Furthermore, the cleaning cover 2 can be connected to an air vent pipe. During the cleaning process, air is pumped into the mixing tank via an air pump. The air impacts the inner wall, causing the water on the inner wall to flow and accelerating water discharge.

[0028] The inner wall of the cleaning sealing cover 2 is provided with a flange 23 that mates with the mixing tank. A rubber ring 24 is provided on the outward side of the flange 23. The rubber ring 24 can contact the top of the mixing tank to provide a seal and prevent water leakage during the cleaning process. The cleaning sealing cover 2 is connected to the rotating frame 11 via a fixed base. In practice, different sizes of cleaning sealing covers 2 can be prepared in advance according to different sizes of mixing tanks. When cleaning a mixing tank of a certain size, the corresponding size of cleaning sealing cover 2 can be replaced.

[0029] The rotating frame 11 is provided with a support assembly 12 for supporting the cleaning shaft 53. The support assembly 12 is located between the cleaning sealing cover 2 and the cleaning bracket 51. The support assembly 12 includes a support frame 121 and a support seat 122 for supporting the cleaning shaft 53 disposed on the support frame 121.

[0030] The inner bottom surface of the cleaning cover 2 is provided with a water guiding surface 25 corresponding to the position of the drain outlet 22. The wastewater generated after cleaning the mixing tank flows into the drain outlet 22 under the guidance of the water guiding surface 25 and flows out of the cleaning cover 2 from the drain outlet 22.

[0031] The paint mixing tank cleaning device also includes a filter water tank 7, which is connected to the drain outlet 22 via a drain pipe 71. The filter water tank 7 can be equipped with a sedimentation tank and a multi-layer filtration structure to initially filter the wastewater generated after cleaning, and then transport it to a wastewater treatment plant for centralized treatment. Of course, depending on the specific benefits of the enterprise, the treated water can also be reused.

[0032] The rotation drive mechanism 6 includes a first connecting seat 61 disposed on the frame 1, a second connecting seat 62 disposed at the bottom of the rotating frame 11, and a rotation drive component 63 connected between the first connecting seat 61 and the second connecting seat 62. The rotation drive component 63 and the first connecting seat 61, and the rotation drive component 63 and the second connecting seat 62, are rotatably connected. In this embodiment, the rotation drive component 63 is a hydraulic cylinder. The cylinder body end of the hydraulic cylinder is connected to the first connecting seat 61, and the output end of the hydraulic cylinder is connected to the second connecting seat 62. When the output end of the hydraulic cylinder extends, the rotating frame 11 is lifted upwards, thereby achieving rotation. At this time, the mixing tank located in the first conveying mechanism 3 is tilted, facilitating the discharge of internal wastewater. Other types of drive components, such as cylinders or lead screws, can also be selected according to actual needs in specific implementations.

[0033] The clamping mechanism 4 includes a first clamping component 41 and a second clamping component 42 disposed on the frame 1. The first clamping component 41 and the second clamping component 42 are symmetrically disposed on both sides of the first conveying mechanism 3. Each of the first clamping component 41 and the second clamping component 42 includes a clamping bracket 411 disposed on the rotating frame 11, a clamping cylinder 412 disposed on the clamping bracket 411, and a clamping member 413 connected to the output end of the clamping cylinder 412. The clamping member 413 is provided with an elastic layer, which can be made of soft elastic materials such as rubber or silicone, which not only protects the mixing tank but also enhances the friction and prevents the mixing tank from moving.

[0034] The paint mixing tank cleaning device also includes a second conveying mechanism 8 mounted on the frame 1 and cooperating with the first conveying mechanism 3. The second conveying mechanism 8 is used to transport the mixing tank to be cleaned to the first conveying mechanism 3 and to receive the cleaned mixing tank from the first conveying mechanism 3. Specifically, the first conveying mechanism 3 and the second conveying mechanism 8 include a conveying support and a conveying roller assembly mounted on the conveying support. In specific implementations, limiting and guiding structures (such as guide rollers mounted vertically on the guide support) can also be provided on both sides of the conveying support to prevent the mixing tank from slipping off the conveying roller assembly during conveying. Additionally, a third conveying mechanism (such as...) can be provided on one side of the second conveying mechanism 8. Figure 1 (front or rear view), and a transfer mechanism for transferring the mixing tank from the second transfer mechanism 8 to the third transfer mechanism, so as to achieve the purpose of automatic transfer of the mixing tank.

[0035] In practical implementation, a clamping mechanism can also be set to press the mixing tank against the cleaning and sealing cover 2. The clamping mechanism may include two linear components, one of which is driven in a direction parallel to the radial direction of the mixing tank, and the other is driven in a direction parallel to the axial direction of the mixing tank. For example, it may be two cylinders. When the mixing tank moves into position, the cylinder parallel to the radial direction of the mixing tank extends, so that the cylinder parallel to the axial direction of the mixing tank reaches the bottom of the mixing tank. At this time, the cylinder parallel to the axial direction of the mixing tank extends and contacts the bottom of the mixing tank, pressing the mixing tank against the cleaning and sealing cover.

[0036] During the cleaning process, the mixing tank to be cleaned is fed into the first conveyor mechanism 3 by the second conveyor mechanism 8. The first conveyor mechanism 3 continues to convey the mixing tank until the top of the mixing tank enters the cleaning sealing cover 2 and contacts the rubber ring 24. Then, the rotating drive mechanism 6 drives the rotating frame 11 to rotate, and the clamping mechanism 4 clamps the mixing tank. After that, the water pump supplies water into the mixing tank through the water inlet pipe 21. At the same time, the cleaning mechanism 5 scrubs the inside of the mixing tank. Since the mixing tank is in an inclined state, the scrubbing wastewater can flow out from the drain outlet 22 under the action of gravity. After cleaning is completed, the rotating drive mechanism 6 resets, the clamping mechanism 4 releases the mixing tank, the first conveyor mechanism 3 sends the mixing tank back to the second conveyor mechanism 8, and the second conveyor 8 sends the mixing tank away, completing one cleaning operation. In addition to cleaning adhesive-coated mixing tanks or mixing buckets, this utility model can also be used for cleaning other types of barrel-shaped containers.
