Description

Technical Field

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

[0002] Cast iron, with its excellent mechanical properties, wear resistance, and cost advantages, is widely used in various industries such as construction, automobiles, and machinery manufacturing. However, cast iron is extremely prone to rusting in humid environments, shortening the service life of cast iron parts and increasing maintenance costs. Therefore, cast iron undergoes anti-corrosion treatment before being put into use. With increasingly stringent environmental protection requirements and consumers' pursuit of product quality, water-based anti-corrosion coatings, as an ideal alternative to traditional solvent-based coatings, have characteristics such as low VOC emissions and environmental friendliness. The production process of water-based anti-corrosion coatings requires filtration to remove impurities and particles from the coating.

[0003] For example, Chinese patent application CN202320218845.2 discloses a filtration device for the production of water-based anti-corrosion coatings. The specific details are as follows: First, the coating is fed into the filter screen through the inlet pipe. Then, the motor is started, and the motor rotates, causing the filter screen to rotate. As the filter screen continuously rotates, the filtered coating falls to the outlet at the bottom of the housing and accumulates. Impurities remain inside the filter screen for subsequent cleaning. The coating adhering to the filter screen is cleaned by brushes on a fixed plate, ensuring the filter screen is clean and does not become clogged. A sealing bearing ensures a seal between the cover and the filter screen, preventing the cover from rotating. Simultaneously, coating can be continuously fed into the filter screen through the inlet pipe. However, this device has the following technical problems: As impurities in the paint are continuously filtered, more and more impurities accumulate inside the filter screen, gradually clogging it and making it difficult for the paint inside the filter screen to flow out, thus affecting the paint production efficiency. It is evident that the above structure is not able to continuously filter impurities in the paint. Utility Model Content

[0004] To address the problem mentioned in the background section that existing technologies are unable to continuously filter impurities in coatings, this utility model provides the following technical solution: A filtration device for the production of water-based anti-corrosion coatings, comprising an outer casing; The outer casing is equipped with a filter structure for filtering the coating.

[0005] The filtration structure includes a filter barrel for filtering the coating, a rotating shaft installed in the middle of the filter barrel, and spiral blades for conveying impurities installed on the outer wall of the rotating shaft.

[0006] The upper end of the outer casing is equipped with a top cover for limiting the position of the filter structure, and the lower end of the top cover is equipped with a slag feeding pipe, with the rotating shaft located inside the slag feeding pipe.

[0007] Furthermore, a feeding pipe is installed at the lower end of the outer casing.

[0008] Furthermore, the upper end of the top cover is equipped with a feeding port for conveying coating into the filter barrel, and the middle part of the top cover is equipped with a slag discharge pipe, the lower end of which is connected to the upper end of the slag delivery pipe.

[0009] Furthermore, a water level sensor is installed on the outer wall of the middle section of the slag delivery pipe, a warning light is installed on the upper end of the top cover, and multiple inclined plates are installed on the outer wall of the bottom of the slag delivery pipe, and the inclined plates are set at an angle.

[0010] Furthermore, the bottom of the slag feeding pipe is provided with multiple slag inlet grooves, and the inclined plate is located on one side of the slag inlet grooves. The middle part of the slag feeding pipe is provided with multiple liquid outlet holes.

[0011] Furthermore, the bottom of the filter barrel is provided with multiple liquid outlet holes II, and the diameter of the cavity of the liquid outlet holes II is larger than that of the cavity of the liquid outlet holes I. Multiple protrusions for agitating the coating are installed inside the filter barrel, and a reduction motor for controlling the rotation of the shaft is installed at the upper end of the shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this invention, when filtering impurities in coatings, a geared motor drives a rotating shaft to rotate, causing the spiral blades and the filter barrel to rotate synchronously. As the filter barrel rotates, the protrusions agitate the coating, guiding it towards the slag inlet trough under the guidance of the inclined plate. This allows impurities to enter the slag delivery pipe through the slag inlet trough. Furthermore, the inclined plate's rotation prevents the coating from clogging the outlet hole. The rotating spiral blades transport impurities from the bottom of the slag delivery pipe to the top, ultimately delivering them to the outside of the outer casing through the slag outlet pipe. Therefore, this invention can continuously transport impurities from inside the filter barrel to the outside, enabling the filter barrel provided by this invention to continuously filter water-based anti-corrosion coatings.

Detailed Implementation

[0015] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0016] Please see Figures 1-4 This utility model provides a filtration device for the production of water-based anti-corrosion coatings, including an outer casing 100. Inside the outer casing 100 is a filtration structure 200 for filtering water-based anti-corrosion coatings. The filtration structure 200 includes a filter barrel 210 for filtering impurities in the coating. A rotating shaft 220 is installed in the middle of the filter barrel 210, and the filter barrel 210 and the rotating shaft 220 are keyed together. The rotating shaft 220 and the filter barrel 210 are fixed by bolts, so that when the rotating shaft 220 rotates, it synchronously drives the filter barrel 210 to rotate.

[0017] A feeding pipe 101 is fixedly installed at the lower end of the outer casing 100. The coating material filtered by the filter barrel 210 falls into the interior of the outer casing 100 and is conveyed to the outside of the outer casing 100 through the feeding pipe 101. A top cover 110 for limiting the filter structure 200 is bolted to the upper end of the outer casing 100. A slag feeding pipe 113 is bolted to the lower end of the top cover 110, and a rotating shaft 220 is located inside the slag feeding pipe 113. A spiral blade 222 for conveying impurities is fixedly installed on the outer wall of the rotating shaft 220. The outer wall of the spiral blade 222 is in contact with the inner wall of the slag feeding pipe 113, so that when the spiral blade 222 rotates inside the slag feeding pipe 113, it can convey the impurities in the slag feeding pipe 113 upward.

[0018] The top cover 110 is equipped with a feeding port 111 for conveying paint into the filter barrel 210. The lower end of the feeding port 111 extends to the upper end of the inner cavity of the filter barrel 210 so that the paint can be directly fed into the filter barrel 210 through the feeding port 111. A slag discharge pipe 112 is fixedly installed in the middle of the top cover 110, and the lower end of the slag discharge pipe 112 is connected to the upper end of the slag feeding pipe 113. When the impurities in the slag feeding pipe 113 are conveyed upward, they are squeezed out through the slag discharge pipe 112. A collection cylinder can be placed at one end of the slag discharge pipe 112 to facilitate the collection of impurities.

[0019] A water level sensor 114 is fixedly installed on the outer wall of the middle section of the slag delivery pipe 113. The height of the water level sensor 114 is three-fifths of the way up the filter tank 210 to prevent excessive paint from overflowing from the top of the filter tank 210. A warning light 115 is installed on the top of the top cover 110. When the water level sensor 114 detects that the paint level has reached the threshold, the warning light 115 will emit a warning, prompting the operator to stop adding paint or reduce the amount of paint added.

[0020] Multiple inclined plates 118 are installed on the bottom outer wall of the slag feeding pipe 113, and the inclined plates 118 are set at an angle, so that when the filter barrel 210 rotates, the coating inside the filter barrel 210 can easily enter the slag feeding pipe 113 through the slag inlet groove 116. Multiple slag inlet grooves 116 are opened at the bottom of the slag feeding pipe 113, and the inclined plates 118 are located on one side of the slag inlet groove 116. Multiple liquid outlet holes 117 are opened on one side of the middle section of the slag feeding pipe 113. The coating inside the slag feeding pipe 113 can easily flow into the filter barrel 210 through the liquid outlet holes 117. The height of the liquid outlet holes 117 is higher than the height of the water level sensor 114 to facilitate the flow of coating into the filter barrel 210.

[0021] The bottom of the filter barrel 210 has multiple outlet holes 211, and the diameter of the outlet holes 211 is larger than that of the outlet holes 117. Multiple protrusions 212 for agitating the coating are installed inside the filter barrel 210. A geared motor 221 for controlling the rotation of the shaft 220 is installed at the upper end of the shaft. A control panel is installed on the outer wall of the outer casing 100. The control panel is electrically connected to the geared motor 221, the water level sensor 114, and the warning light 115. The geared motor 221 is fixed to the middle of the top cover 110 via a flange. When filtering the coating, the coating is fed into the filter barrel 210 through the feed inlet 111, the geared motor 221 starts, and drives the shaft 220 to rotate. The rotating shaft 220 rotates within the slag feeding pipe 113, transporting impurities from the bottom of the slag feeding pipe 113 to the top. The impurities are then transported through the slag discharge pipe 112 to the outside of the outer casing 100. Simultaneously, the filter barrel 210 rotates, causing the inclined plate 118 to scrape impurities from the inner wall of the filter barrel 210. The filter barrel 210 drives multiple protrusions 212 to agitate the coating material, guiding it towards the slag inlet trough 116 under the guidance of the inclined plate 118. This allows impurities to enter the slag feeding pipe 113 through the slag inlet trough 116. As the rotating shaft 222 rotates, it transports the impurities to the top of the slag feeding pipe 113, ultimately transporting them out through the slag discharge pipe 112 to the outside of the outer casing 100.

[0022] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
