Description

Technical Field

[0001] This utility model relates to the technical field of water-based coating treatment equipment, and in particular to a water-based coating impurity treatment device. Background Technology

[0002] All coatings that use water as a solvent or dispersion medium can be called water-based coatings. Based on the type of binder in the coating, water-based coatings are divided into two main categories: natural water-based coatings using natural substances or minerals (such as potassium silicate) and petrochemical water-based coatings using synthetic resins (such as acrylic resins). This section will only discuss water-based coatings using synthetic resins.

[0003] In practice, water-based paints in existing technologies inevitably introduce some impurities during the production process. If these impurities are not filtered out, they will affect the subsequent use of the water-based paints. Existing filtration equipment is not very convenient, cannot be adjusted in a timely manner according to changes in the work scenario, and cannot achieve multi-stage processing efficiency, which affects the quality of the final product and causes many inconveniences.

[0004] Therefore, this utility model provides a device for treating impurities in water-based coatings. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a device for treating impurities in water-based coatings.

[0007] The top of the paint impurity treatment box is provided with a collection trough, and a first filter plate is installed inside the collection trough. The first filter plate has equidistantly distributed first filter holes inside, and a paint impurity treatment tank extending into the paint impurity treatment box is installed inside the first filter plate.

[0008] The interior of the paint impurity treatment tank is equipped with a support plate. Symmetrically distributed limiting installation blocks are installed at the bottom of the support plate.

The external pipe 18 assists in connecting other pipes to ensure normal transportation.

[0039] In this scheme, a control panel 11 is fixedly connected to the outside of the paint impurity treatment box 1.

[0040] Working principle:

[0041] like Figures 1-5 As shown:

[0042] By setting up a paint impurity treatment box 1, a collection tank 2, a paint impurity treatment vessel 3, and a supporting horizontal plate 4, when in use, the control panel 11 is opened. The paint impurity treatment vessel 3 and the outer side of the second valve 36 are coated with waterproof paint to prevent water leakage and extend the service life of the equipment. Anti-corrosion materials can be applied as needed.

[0043] The bottom mounting cover 33 and the support base 34 are used to support the entire paint impurity treatment tank 3. The third valve 38 is used to control the opening of the water inlet pipe 37 so that water can enter normally through the water inlet pipe 37. The second valve 36 is used to control the opening of the drain pipe 35 so that the water-based paint that has been treated inside the paint impurity treatment tank 3 can be discharged into the paint impurity treatment box 1 for further sedimentation and filtration.

[0044] The drive motor 5 and the worm gear reducer 52 are positioned and installed by the motor mounting bracket 51. When the drive motor 5 runs, the worm gear reducer 52 drives the rotating rod 39 to rotate inside the filter element 31, thereby heating and stirring the water-based paint entering the paint impurity treatment tank 3, which speeds up the efficiency of impurity treatment.

[0045] The first valve 17 is used to control the opening of the discharge pipe 16. The discharge pipe 16 is used to output the water-based paint that has undergone impurity treatment inside the paint impurity treatment box 1.

[0046] The control panel 11 is used to control the operation of the first valve 17, the second valve 36, the third valve 38, the drive motor 5, the motor mounting bracket 51, and the worm gear reducer 52, thus realizing unified management of electrical equipment.

[0047] The push rod 14 facilitates manual pushing of the entire equipment, and the handle 15 facilitates auxiliary handling of the entire equipment when necessary. When in use, the dust cover 23 can be removed to directly replenish the auxiliary impurity mixing solution into the paint impurity treatment box 1.

[0048] The bottom of each of the four bottom positioning frames 12 is threaded with positioning bolts that extend to the inner wall of the bottom of the paint impurity treatment box 1. The positioning bolts are used to position and install the bottom positioning frame 12 and the paint impurity treatment box 1, thereby achieving the connection effect between the casters 13 and the paint impurity treatment box 1. The four casters 13 drive the entire equipment to move normally, meeting the needs of operation in different locations. The paint impurity treatment tank 3 and the paint impurity treatment box 1 perform dual impurity filtration treatment, which improves the final water-based paint filtration efficiency, thus facilitating subsequent normal use.
