Description

Technical Field

[0001] This utility model relates to the field of anti-corrosion material coating, specifically an anti-sedimentation structure of an intelligent anti-corrosion material coating device for sewage tanks. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] Wastewater treatment systems, as a crucial component of urban infrastructure, are vital not only for urban sanitation but also for ecological civilization construction. Inadequate anti-seepage and anti-corrosion measures allow wastewater to seep into the tank structure, eroding concrete and other building materials, thus affecting the tank's load-bearing capacity and lifespan. Current anti-seepage and anti-corrosion methods involve coating the wastewater tank surface with anti-corrosion materials. This coating is applied manually using a roller or spray gun. Both methods are manual, leading to uneven coating thickness and inaccuracies, resulting in areas with poor anti-seepage and anti-corrosion performance. Leaks in these areas can cause environmental pollution.

[0004] Therefore, in order to improve the anti-seepage and anti-corrosion performance of the surface of sewage tanks, it is necessary to apply multiple layers of anti-seepage and anti-corrosion materials to the surface of sewage tanks at one time using equipment. Each layer of coating needs to be placed separately inside the tank. In order to prevent the coating from settling at the bottom of the tank and affecting the coating effect of the equipment on the surface of the sewage tank, it is necessary to have an anti-settling function, thereby promoting the circulation of the coating inside the tank and ensuring that the coating is evenly distributed inside the tank. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-settling structure for an intelligent anti-corrosion material coating equipment for sewage tanks. It is used to stir the coating inside the tank to promote dispersion, and then lift the coating deposited at the bottom of the tank along the guide component and then fall down along the top of the guide component, forming a regular flow pattern. This promotes the flow of the coating inside the tank and avoids the coating settling during the construction process, which would lead to different coating effects in different areas and affect the overall construction effect.

[0006] To achieve the above objectives, this utility model employs the following technical solution: An anti-sedimentation structure for an intelligent anti-corrosion material coating equipment for sewage tanks is provided. The anti-sedimentation structure is installed inside the storage tank and includes a flow guide and a stirring device that cooperates with the flow guide. The guide component is fixedly installed inside the storage tank. The blade of the stirring device drives the coating material at the bottom of the storage tank to disperse from the bottom of the storage tank. The stirring device drives the coating material inside the storage tank to be lifted along the guide component and released at the top, and then circulates to the bottom of the storage tank.

[0007] The stirring device includes a main shaft, a drive motor connected to the main shaft, and a conveying shaft sleeved with the main shaft; the outer side of the conveying shaft is equipped with auger blades, and the bottom of the main shaft is provided with a cutter head and a stirring rod. After the cutter head rotates, it is pushed towards the bottom of the storage tank.

[0008] The height of the guide component is adapted to the conveying shaft, and the guide component is sleeved with the conveying shaft with the inner diameter of the guide component being larger than the maximum outer diameter of the conveying shaft. The top of the guide is provided with a clearance opening, and the guide is provided with multiple overflow holes along the axial direction.

[0009] The front end of the stirring rod is equipped with a flexible scraper.

[0010] The diameter of the overflow hole gradually decreases from the top to the bottom.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Used to stir the coating inside the tank to promote dispersion, and then lift the coating deposited at the bottom of the tank along the guide, and then fall down along the top of the guide, forming a regular flow pattern, thereby promoting the flow of the coating inside the tank and avoiding the sedimentation of the coating during construction, which would lead to different coating effects in different areas and affect the overall construction effect.

[0016] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0017] This utility model describes an anti-sedimentation structure for an intelligent anti-corrosion material coating device for sewage tanks. Before describing the structure, the composition of each layer of the coating is briefly introduced. There are three storage tanks, each storing one type of coating. The three coatings are isolated from each other. The coatings extruded from the corresponding dies are in three layers: the bottom layer is a flexible layer made of amino-terminated polyether-modified waterborne epoxy resin. The modified resin coating changes the traditional brittleness, gaining toughness and ductility; the middle layer is a transition layer, made of a 3:7 blend of waterborne polyurethane and epoxy resin, with nano-titanium dioxide introduced to construct a semi-interpenetrating network structure; the top layer is a rigid layer made of fluorocarbon-modified polyurea elastomer, with added silicon carbide wear-resistant particles, improving wear resistance by 3 times compared to ordinary coatings. Regarding the composition of the three coatings, the heavier nanoparticles or wear-resistant particles will accumulate at the bottom of the tank under gravity, so the storage tanks must have anti-sedimentation functions. The specific structure is as follows: As shown in the attached diagram of the instruction manual. Figures 1-3 As shown, it includes a flow guide 1 disposed inside the storage tank and a stirring device that cooperates with the flow guide 1; the stirring device includes a main shaft 3, a drive motor 4 connected to the main shaft 3, and a conveying shaft 5 sleeved with the main shaft 3; The outer side of the conveying shaft 5 is equipped with auger blades 9, and the bottom of the main shaft 3 is equipped with a cutter head 2 and a stirring rod. The cutter head 2 of the stirring device drives the coating at the bottom of the storage tank to disperse from the bottom of the storage tank. The coating at the bottom of the storage tank is pushed upward by the reaction force. Then, the auger blades 9 on the outer side of the conveying shaft 5 drive the backflowing large molecular particles to rise along the auger blades 9 inside the guide member 1. The coating inside the storage tank is lifted along the guide member 1 and released at the top, and then circulates to the bottom of the storage tank.

[0018] Therefore, the height of the guide component 1 is adapted to the conveying shaft 5. The guide component 1 is sleeved with the conveying shaft 5, and the inner diameter of the guide component 1 is larger than the maximum outer diameter of the conveying shaft 5. The top of the guide component 1 is provided with a relief port 6, and the guide component 1 is provided with multiple overflow holes 7 in the axial direction. In order to avoid the circulation effect and the drop in liquid level inside the storage tank due to the excessive height of the relief port 6 at the top of the guide component 1 during the circulation process, further improvements are made: the guide component 1 is provided with multiple overflow holes 7 in the axial direction. The diameter of the overflow holes 7 gradually decreases from the top to the bottom. After setting the overflow holes 7, when the auger blades 9 drive the liquid to rise, a small portion will overflow from the overflow holes 7, thereby promoting circulation. And after the liquid level drops, it can also circulate outward from the overflow holes 7. When the liquid level is too low, the overflow holes 7 cooperate with the cutter head 2 to form a circulation effect that promotes dispersion.

[0019] To prevent the coating from forming a film on the surface of the tank, a flexible scraper 8 is provided at the front end of the stirring rod. Therefore, when the blade 2 is stirring, the flexible scraper 8 is driven to clean the inner wall of the tank.

[0020] In summary, this application is used to stir the coating inside the tank to promote dispersion, and then lift the coating deposited at the bottom of the tank along the guide 1 and then fall along the top of the guide 1, forming a regular flow pattern, thereby promoting the flow of the coating inside the tank and avoiding sedimentation of the coating during construction, which would lead to different coating effects in different areas and affect the overall construction effect.
