Description

Technical Field

[0001] This utility model relates to the field of water-soluble varnish storage technology, specifically to a water-soluble varnish storage tank that prevents settling. Background Technology

[0002] Water-soluble varnish is an industrial product used for rust and corrosion prevention treatment of metal surfaces after electroplating. It has the properties of being fingerprint-resistant, heat-resistant, moisture-resistant, acid-resistant, and alkali-resistant.

[0003] Water-soluble varnishes use water as a solvent and contain solid components such as resins, pigments, and fillers. During long-term storage, particles are prone to settling due to gravity, leading to uneven concentration between layers and affecting performance. Traditional storage tanks often rely on periodic manual stirring or external stirring devices, which suffers from high energy consumption, incomplete stirring, and residue buildup in the bottom corners of the tank. Furthermore, water-soluble varnishes are corrosive to metal tanks, further exacerbating the risk of sedimentation and contamination. Therefore, we propose a sedimentation-resistant water-soluble varnish storage tank to address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a water-soluble varnish storage tank that prevents settling, thus solving the problems mentioned in the background section.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a storage tank for anti-settling water-soluble varnish, including a tank body, wherein an inlet pipe and an outlet pipe are respectively connected to the tank body, and further comprising:

[0006] The movable structure located inside the tank.

[0007] The movable structure includes a rotating shaft, which is rotatably connected to the tank body. A stirring blade is fixedly installed on the rotating shaft, and an anti-settling structure is provided on the rotating shaft.

[0008] The anti-sedimentation structure includes filter disc one, filter disc two, and filter disc three. Filter disc one is fixedly installed on the bottom end of the rotating shaft, and the interiors of filter disc two and filter disc three are movably installed on the outer wall of the rotating shaft.

[0009] Furthermore, the active structure also includes a drive motor, which is fixedly installed at the top of the tank. A rotating shaft is fixedly installed at the output end of the drive motor. There are several stirring blades, and the interior of each stirring blade is distributed on the outer wall of the rotating shaft.

[0010] Furthermore, the anti-sedimentation structure also includes an annular sliding groove, which is formed on the lower surface of filter disc one. A sliding block is slidably connected inside the annular sliding groove. Hydraulic cylinders are symmetrically fixedly installed at the bottom of the inner wall of the tank. A sliding block is fixedly installed at the output end of the hydraulic cylinder. T-shaped columns one are symmetrically fixedly installed on the upper surface of filter disc one. A baffle one is fixedly installed on the outer wall of T-shaped columns one. Through holes are symmetrically formed inside filter disc two and filter disc three. T-shaped columns one are movably installed inside filter disc two through the through holes. T-shaped columns two are symmetrically fixedly installed on the upper surface of filter disc two. A baffle two is fixedly installed on the outer wall of T-shaped columns two. T-shaped columns two are movably installed inside filter disc three through the through holes.

[0011] Furthermore, a programmable controller is fixedly installed at the top of the tank, and a support frame is fixedly installed at the bottom of the outer wall of the tank.

[0012] By adopting the above technical solution, the programmable controller is an industrial-grade logic control device with a timing module, digital input / output interface and pulse output function. It is used to control the coordinated action of the drive motor and hydraulic cylinder according to the preset program. For example, controllers with equivalent functions such as Siemens S7-1200 series and Mitsubishi FX3U series can be used.

[0013] Furthermore, the outer walls of filter disc one, filter disc two, and filter disc three are in contact with the inner wall of the tank.

[0014] Furthermore, the drive motor and hydraulic cylinder are electrically connected to the programmable controller.

[0015] The beneficial effects of this utility model are:

[0016] 1. This anti-settling water-soluble varnish storage tank uses a programmable controller to automate the control of the drive motor and hydraulic cylinder. It allows for preset stirring frequency and filter disc movement cycles, dynamically adjusting the anti-settling strategy based on storage time and varnish condition, reducing manual intervention and energy consumption. The drive motor rotates the shaft and stirring blades, achieving regular stirring of the water-soluble varnish within the tank, initially dispersing solid particles and preventing large-scale settling. In the anti-settling structure, the outer walls of filter discs one, two, and three contact the inner wall of the tank. As they slide up and down under the drive of the hydraulic cylinder, they effectively scrape off particles adhering to the tank wall and bottom, solving the problem of traditional stirring devices failing to reach the dead corners of the tank wall and bottom, thus improving stirring uniformity.

[0017] 2. In this anti-settling water-soluble varnish storage tank, filter disc one is connected to a sliding block via an annular sliding groove. Under the action of a hydraulic cylinder, it can move vertically along the tank body, driving filter disc two and filter disc three to move in conjunction with the T-shaped column and through-hole structure. When filter disc two and filter disc three slide up and down, their baffle one and baffle two push the liquid to form vertical convection. Combined with the horizontal stirring of the stirring blades, a three-dimensional mixing flow field is formed, which further breaks up particle agglomerates and prevents the stratification of components with different densities.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figures 1-5 A water-soluble varnish storage tank for preventing settling includes a tank body 1, with an inlet pipe 2 and an outlet pipe 3 respectively connected to the tank body 1, and further includes:

[0027] The movable structure 4 is installed inside the tank 1.

[0028] Among them, the movable structure 4 includes a rotating shaft 42, which is rotatably connected inside the tank 1. A stirring blade 43 is fixedly installed on the rotating shaft 42, and an anti-settling structure 44 is provided on the rotating shaft 42.

[0029] The anti-sedimentation structure 44 includes filter disc 1 441, filter disc 2 447 and filter disc 3 448. Filter disc 1 441 is fixedly installed on the bottom end of the rotating shaft 42, and the interiors of filter disc 2 447 and filter disc 3 448 are respectively movably installed on the outer wall of the rotating shaft 42.

[0030] Reference Figures 1-3 As shown, the active structure 4 also includes a drive motor 41, which is fixedly installed at the top of the tank 1. A rotating shaft 42 is fixedly installed at the output end of the drive motor 41. There are several stirring blades 43, and the interior of each stirring blade 43 is distributed on the outer wall of the rotating shaft 42.

[0031] In this embodiment, the programmable controller 5 realizes automated control of the drive motor 41 and the hydraulic cylinder 444. It can preset the stirring frequency and filter disc movement cycle, and dynamically adjust the anti-settling strategy according to the storage time and the state of the varnish, reducing manual intervention and energy consumption. The drive motor 4 drives the rotating shaft 42 and the stirring blades 43 to rotate, realizing the regular stirring of the water-soluble varnish in the tank 1, initially dispersing solid particles and avoiding large-scale sedimentation. The outer walls of the filter discs 441, 447, and 448 in the anti-settling structure 4 are in contact with the inner wall of the tank 1. When they slide up and down under the drive of the hydraulic cylinder 444, they can effectively scrape off the particles attached to the tank wall and bottom, solving the problem that traditional stirring devices cannot reach the dead corners of the tank wall and bottom, and improving the uniformity of stirring.

[0032] Reference Figures 2-5 As shown, the anti-sedimentation structure 44 also includes an annular sliding groove 442, which is opened on the lower surface of filter disc 1 441. A sliding block 443 is slidably connected inside the annular sliding groove 442. A hydraulic cylinder 444 is symmetrically fixedly installed at the bottom of the inner wall of the tank 1. A sliding block 443 is fixedly installed at the output end of the hydraulic cylinder 444. A T-shaped column 445 is symmetrically fixedly installed on the upper surface of filter disc 1 441. A baffle 446 is fixedly installed on the outer wall of the T-shaped column 445. Through holes 449 are symmetrically opened inside filter disc 2 447 and filter disc 3 448 respectively. A T-shaped column 445 is movably installed inside filter disc 2 447 through the through hole 449. A T-shaped column 4410 is symmetrically fixedly installed on the upper surface of filter disc 2 447. A baffle 4411 is fixedly installed on the outer wall of the T-shaped column 4410. A T-shaped column 4410 is movably installed inside filter disc 3 448 through the through hole 449.

[0033] In this embodiment, filter disc 441 is connected to sliding block 443 through an annular sliding groove 442. Under the action of hydraulic cylinder 444, it can move vertically along tank 1, driving filter disc 447 and filter disc 448 to move in linkage through T-shaped column and through hole 449. When filter disc 447 and filter disc 448 slide up and down, their baffles 446 and 4411 push the liquid to form vertical convection. Combined with the horizontal stirring of stirring blade 43, a three-dimensional mixing flow field is formed, which further breaks up particle agglomerates and prevents the stratification of components with different densities.

[0034] Reference Figure 1 , Figure 2 As shown, a programmable controller 5 is fixedly installed on the top of the tank 1, and a support frame 6 is fixedly installed on the bottom of the outer wall of the tank 1. By adopting the above technical solution, the programmable controller 5 is an industrial-grade logic control device with a timing module, digital input / output interface and pulse output function. It is used to control the coordinated action of the drive motor 41 and the hydraulic cylinder 444 according to a preset program. For example, a controller with equivalent functions such as Siemens S7-1200 series or Mitsubishi FX3U series can be used.

[0035] In this embodiment, the programmable controller 5 automatically adjusts the speed of the drive motor 41 and the operating cycle of the hydraulic cylinder 444 according to parameters such as storage time and varnish type, so as to switch between "energy-saving mode" and "enhanced mode". For example, the stirring frequency is reduced during short-term storage and the disturbance is enhanced during long-term storage, so as to optimize energy consumption while ensuring the anti-settling effect.

[0036] Reference Figure 2 , Figure 3 As shown, the outer walls of filter disc 1 (441), filter disc 2 (447), and filter disc 3 (448) are in contact with the inner wall of tank 1.

[0037] Reference Figures 1-3 As shown, the drive motor 41 and the hydraulic cylinder 444 are electrically connected to the programmable controller 5.

[0038] In this embodiment, the programmable controller 5 controls the power supply of the drive motor 41 through the output module to start and stop it. The drive motor 41 is a servo motor, and its control terminal is controlled by an external power supply control device through a wiring harness. The hydraulic cylinder 444 is a single-piston hydraulic cylinder. The inlet and outlet of the hydraulic cylinder 444 are respectively connected to one side of the external liquid reversing valve through oil pressure pipes. The other side of the external liquid reversing valve is connected to the inlet and outlet of the hydraulic pump through oil pressure pipes, thereby controlling the output end of the hydraulic cylinder 444 to move up and down.

[0039] During use, after the drive motor 41 starts, it drives the rotating shaft 42 and the stirring blade 43 to rotate, which initially stirs the varnish in the tank, lifts up the solid particles deposited at the bottom and disperses them into the liquid, forming a basic mixing flow field; the programmable controller 5 controls the output end of the hydraulic cylinder 444 to move up and down according to the preset program or real-time monitoring signal, pushing the sliding block 443 to slide in the annular sliding groove 442, which drives the filter disc 441 to rise and fall vertically.

[0040] When filter disc 441 rises, the T-shaped pillars 445 on its surface push filter disc 447 to rise synchronously through the through holes 449. The T-shaped pillars 4410 of filter disc 447 then drive filter disc 448 to move upward. At this time, baffles 446 and 4411 push the lower liquid upward. Conversely, when filter disc 441 falls, the three filter discs move downward synchronously, pressing the upper liquid to the bottom, forming a convective motion that cycles up and down.

[0041] Because the outer wall of the filter disc is in close contact with the inner wall of the tank 1, it can effectively scrape off the particles attached to the tank wall during the lifting process, thus avoiding particle accumulation.

[0042] The horizontal stirring of the stirring blades 43 combined with the vertical lifting of the filter plate creates a composite flow field of "horizontal rotation + vertical convection" in the tank, continuously disturbing solid particles of different sizes and preventing sedimentation caused by gravity.

[0043] For varnishes that have been stored for a long time or have developed stratification, the programmable controller 5 can increase the frequency of filter disc movement or the intensity of stirring. By enhancing convection and wall scraping, it can eliminate the bottom deposit layer and ensure uniform varnish concentration in the tank.

[0044] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
