Description

Technical Field

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

[0002] Water-based coatings include three types: water-soluble coatings, water-dilutable coatings, and water-dispersible coatings. Water-soluble coatings use water-soluble resins as film-forming agents, with polyvinyl alcohol and its various modified forms being representative examples. Other types include water-soluble alkyd resins, water-soluble epoxy resins, and inorganic polymer water-based resins.

[0003] Currently, water-based coatings require filtration during processing to remove impurities. A Chinese patent (CN222566974U) discloses a waterproof coating filter that utilizes a filter assembly for filtration, followed by cleaning with a scraper. However, this structure pauses filtration during cleaning, affecting overall filtration efficiency. Utility Model Content

[0004] The present invention aims to address the shortcomings of the prior art by providing a filtration device for the production of water-based coatings.

[0005] To achieve the above objectives, this utility model adopts the following technical solution:

[0006] A filtration device for water-based coating production includes a filter. A vertical partition is located in the middle of the filter, dividing the filter cavity into left and right filtration chambers. A horizontal plate is located at the top of the vertical partition, and a conversion channel is provided between the horizontal plate and the top plate of the filter. A feed inlet is located directly above the horizontal plate at the top of the filter. A screw is installed between the inner walls of the left and right sides of the filter within the conversion channel. The screw is connected to a drive motor, and a sealing baffle is threaded onto the screw. The sealing baffle is movable between the horizontal plate and the top plate of the filter. A discharge hopper is located at the bottom of each filtration chamber, and a discharge valve is installed at the bottom of the discharge hopper. An inclined filter screen is installed in each filtration chamber. A cleaning port is located at the lower end of the inclined filter screen on the side wall of the filtration chamber, and a sealing door is located outside the cleaning port.

[0007] Protective covers are fixed on both sides of the closed baffle, and the protective covers are placed above the lead screw.

[0008] The protective cover has an n-shaped cross-section.

[0009] Each filter has a suction pipe on its side wall below the inclined filter screen. The suction pipe is connected to a vacuum pump. A baffle is installed on the inner wall of the filter above the suction pipe.

[0010] The baffle includes a horizontal plate and a vertical plate, with an inclined guide plate between the horizontal plate and the vertical plate.

[0011] The horizontal plate has downward-sloping guide plates on both sides.

[0012] The sealed door has a handle on the outside.

[0013] The beneficial effects of this utility model are: by using a closed baffle to connect the feed inlet to the two filter chambers separately, the filter structure can be cleaned without stopping the machine, ensuring the normal operation of the filtration process and improving the filtration efficiency.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0024] like Figures 1 to 4 As shown, a filtration device for water-based coating production includes a filter 1, a vertical partition 2, a filter chamber 3, a horizontal plate 4, a feed inlet 5, a lead screw 6, a drive motor 7, a closed baffle 8, a discharge hopper 9, a discharge valve 10, an inclined filter screen 11, a cleaning port 12, a sealing door 13, a protective cover 14, a suction pipe 15, a baffle 16, a guide plate 17, and a handle 18.

[0025] A vertical partition 2 is provided in the middle of the filter 1. The vertical partition 2 divides the inner cavity of the filter 1 into two filter chambers 3, left and right. Each filter chamber 3 is provided with a discharge hopper 9 at the bottom, and a discharge valve 10 is installed at the bottom of the discharge hopper 9.

[0026] By setting up two filter chambers, filtration and cleaning operations can be performed alternately, avoiding downtime and ensuring the normal operation of the filtration process.

[0027] A horizontal plate 4 is provided at the top of the vertical partition 2. A conversion channel is provided between the horizontal plate 4 and the top plate of the filter 1. A feed inlet 5 is provided at the top of the filter 1 directly above the horizontal plate 4. A lead screw 6 is installed in the conversion channel between the inner walls of the left and right sides of the filter 1. The lead screw 6 is connected to a drive motor 7. A sealing baffle 8 is threaded on the lead screw 6. The sealing baffle 8 is movable between the horizontal plate 4 and the top plate of the filter 1.

[0028] The horizontal plate 4 has downward-sloping guide plates 17 on both the left and right sides.

[0029] The drive motor 7 drives the lead screw 6 to rotate, and the closed baffle 8 on the lead screw 6 moves to realize the connection between the feed inlet 5 and the left filter chamber 3 or the right filter chamber 3, thereby realizing the function of filtering and cleaning at the same time.

[0030] Protective covers 14 are fixed on both sides of the closed baffle 8, and the protective covers 14 are installed above the lead screw 6. The protective covers 14 can shield the lead screw 6 below the feed inlet 5, preventing paint from adhering to the lead screw 6 and affecting the normal movement of the closed baffle 8.

[0031] The protective cover 14 has an n-shaped cross-section. The shape of the protective cover 14 can be... Figure 3 The structure shown can also be Figure 4 The structure shown, Figure 4 The structure shown is more conducive to the downward flow of materials.

[0033] The sealed door 13 is equipped with a handle 18 on the outside.

[0034] The inclined filter screen 11 is designed so that the impurities remaining on the screen surface after filtration can be concentrated at the lower end of the inclined filter screen 11 under the action of gravity. This not only prevents the entire screen surface from being blocked quickly, but also makes it easier to clean from the cleaning port 12.

[0035] Each filter 1 has a suction pipe 15 on its side wall below the inclined filter screen 11. The suction pipe 15 is connected to a vacuum pump. A baffle 16 is provided on the inner wall of the filter 1 above the suction pipe 15.

[0036] The baffle 16 includes a horizontal plate and a vertical plate, and an inclined guide plate is provided between the horizontal plate and the vertical plate.

[0037] The suction pipe 15 can extract gas from the filter chamber 3, creating a negative pressure filtration effect for better filtration and improved filtration efficiency.
