A spray device for anti-corrosion treatment of storage tank surface

Abstract

This utility model discloses a spray device for anti-corrosion treatment of the surface of a storage tank, relating to the field of surface treatment technology for storage tanks. It includes a top plate with a rotary motor mounted on top and a spray mechanism mounted on the bottom. The device uses a rotating rod to drive a drive groove, applying a propulsive force to a force-bearing block. This causes a moving frame to move along a set trajectory, driving a sliding block to slide along the surface of a sliding rod and thus driving the nozzle to complete the spraying operation. Initially, the nozzle sprays from top to bottom. As rotation continues, the spraying area gradually expands. When the force-bearing block reaches the end of the groove, its movement direction reverses due to changes in the groove's contour, causing the nozzle to return upwards, completing one spray cycle. This reciprocating process improves the spray coverage and uniformity. Furthermore, the rotating frame allows for multi-angle rotation of the nozzle, further enhancing the all-around spraying effect on containers such as storage tanks.

Description

Technical Field

[0001] This utility model relates to the field of surface treatment technology for storage tanks, and in particular to a spray device for anti-corrosion treatment of the surface of storage tanks. Background Technology

[0002] Storage tanks exposed to the atmosphere, water, soil, or chemical media for extended periods are prone to oxidation corrosion (such as rust), electrochemical corrosion (such as the formation of micro-batteries from contact between different metals), or chemical corrosion (such as erosion by acidic or alkaline liquids). Anti-corrosion treatments (such as applying rust-preventive paint, epoxy resin coatings, or hot-dip galvanizing) can form an insulating layer on the metal surface, preventing corrosive media from directly contacting the substrate, thereby extending the equipment's service life.

[0003] For example, CN213529297U discloses an automatic rotating spraying device for environmentally friendly paint on the surface of an iron drum, which includes an electric turntable, a long oil cylinder, a U-shaped block, a U-shaped long plate, a strip block, a spray head, a micro motor, a long screw, rectangular strip holes, rectangular grooves, strip grooves, connecting strip holes, an adjusting screw, a bearing seat, a return spring, and a square sliding plate.

[0004] However, in existing technologies, traditional spraying devices mostly use fixed nozzles or move in one direction, which cannot cover the curved surfaces and dead corners of containers. There are unsprayed areas on the container surface, resulting in incomplete cleaning or uneven coating. The movement of the nozzles depends on manual adjustment or simple linear reciprocating motion, lacking multi-angle linkage, making it difficult to adapt to containers with complex shapes. The spraying efficiency is low, requiring multiple clamping or manual respraying, which increases costs and time. When spraying with a fixed nozzle, the central area and the edges are also affected. Utility Model Content

[0005] The purpose of this invention is to solve the problem that traditional spraying devices in the prior art mostly use fixed nozzles or move in one direction, which cannot cover the curved surface and dead corners of containers, leaving unsprayed areas on the container surface, resulting in incomplete cleaning or uneven coating. Therefore, this invention proposes a spraying device for anti-corrosion treatment of storage tank surfaces.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a spray device for anti-corrosion treatment of the surface of a storage tank, comprising a top plate, a rotary motor installed on the top of the top plate, and a spraying mechanism installed at the bottom of the top plate;

[0007] The spraying mechanism includes a rotating frame, with two support frames symmetrically fixedly connected to one side of the rotating frame. A rotating rod is rotatably connected between the two support frames. Two sliding rods are provided on one side of the rotating rod. Sliding blocks are slidably connected to the surfaces of the two sliding rods. A movable frame is rotatably connected to the inner side of the sliding blocks. Three force-bearing blocks are fixedly connected to the inner side of the movable frame. A drive groove is provided on the surface of the rotating rod, and the drive groove is slidably connected to the force-bearing blocks.

[0008] Preferably, a geared motor is installed on the top of one of the support frames, and the output end of the geared motor is fixedly connected to the rotating rod.

[0009] Preferably, a guide block is fixedly connected to one side of the top of the rotating frame, and a track is slidably connected to the inner side of the guide block.

[0010] Preferably, the top of the track is fixedly connected to the bottom of the top plate.

[0011] Preferably, the top of one end of the rotating frame is fixedly connected to the output end of the rotary motor.

[0012] Preferably, a nozzle is installed on one side of the top of the rotating rod, and the nozzle is fixedly connected to an external water pipe.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the rotating rod drives the drive groove to apply a propulsive force to the force-bearing block, causing the moving frame to move along a set trajectory, thereby driving the sliding block to slide along the surface of the sliding rod and driving the nozzle to complete the spraying operation. Initially, the nozzle sprays from top to bottom. As the rotation continues, the spraying area gradually expands. When the force-bearing block reaches the end of the groove, its movement direction reverses due to the change in the groove contour, driving the nozzle to achieve an upward return motion and completing one spraying cycle. This reciprocating process improves the spraying coverage and uniformity. In addition, the rotating frame can realize multi-angle rotation of the nozzle, further enhancing the all-round spraying treatment effect on container workpieces such as storage tanks.

[0015] 2. In this utility model, a rotary motor drives a rotating frame to rotate stably, and a linkage guide block slides along the track to achieve circumferential sliding, which drives the nozzle to move around the storage tank to achieve full coverage and build a horizontal spray trajectory. At the same time, a reduction motor outputs low speed and high torque to drive a rotating rod to move the nozzle up and down, forming vertical adjustment and realizing a three-dimensional spray path. The system achieves synchronous adjustment of the nozzle in the horizontal and vertical directions through the coordinated control of two motors, so that the spray coverage is comprehensive and uniform.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-4 As shown, this utility model provides a spray device for anti-corrosion treatment of the surface of a storage tank, including a top plate 1, a rotary motor 2 installed on the top of the top plate 1, and a spraying mechanism 3 installed at the bottom of the top plate 1;

[0024] The spraying mechanism 3 includes a rotating frame 32. Two support frames 341 are symmetrically fixedly connected to one side of the rotating frame 32. A rotating rod 34 is rotatably connected between the two support frames 341. Two sliding rods 35 are provided on one side of the rotating rod 34. Sliding blocks 36 are slidably connected to the surfaces of the two sliding rods 35. A movable frame 38 is rotatably connected to the inner side of the sliding block 36. Three force-bearing blocks 39 are fixedly connected to the inner side of the movable frame 38. A drive groove 342 is opened on the surface of the rotating rod 34. The drive groove 342 is slidably connected to the force-bearing blocks 39.

[0025] The specific setup and function of this embodiment are described below. In this device, the rotating rod 34 begins to rotate under the drive of an external power device. Its outer surface is provided with a drive groove 342, the contour of which is designed to gradually apply a propulsive force in a specific direction during rotation. As the rotating rod 34 rotates, the drive groove 342 applies a pushing force to the force-bearing block 39. The force-bearing block 39, under this force, tends to move and transmits the force to the movable frame 38 connected to it. Driven by the force-bearing block 39, the movable frame 38 moves smoothly along a set trajectory, thereby causing the sliding block 36 connected to it to begin sliding along the surface of the sliding rod 35.

[0026] During the sliding process, the sliding block 36 drives the nozzle 37 mounted on it to move synchronously, achieving continuous changes in the spray position. In the initial stage, due to the structural design of the drive groove 342, the sliding block 36 first slides downward along the longitudinal direction of the slide rod 35, causing the nozzle 37 to complete the top-down spraying action. As the rotating rod 34 continues to rotate, the drive groove 342 continues to apply force to the force-bearing block 39, causing the moving frame 38 and the force-bearing block 39 to continue to move downward, realizing the gradual expansion of the spray area.

[0027] After the force-bearing block 39 moves to the end position in the drive groove 342, guided by the change in the groove's contour, its movement direction begins to reverse. At this time, it drives the sliding block 36 to slide upward, thereby causing the nozzle 37 to begin to move in the opposite direction, realizing the return of the spray path. This reciprocating motion not only improves the coverage and uniformity of the spray, but also ensures comprehensive spraying treatment of the target area in the vertical direction.

[0028] Furthermore, this structure includes a rotating frame 32, which can rotate around a central axis. This allows the nozzles 37 to spray vertically while simultaneously achieving multi-angle and multi-directional spray coverage of the storage tank via the rotation of the frame 32, significantly improving the comprehensiveness and efficiency of the spraying operation. The overall structural design combines stability and flexibility, making it suitable for automated and efficient spraying of containers such as storage tanks.

[0029] Example 2: Figures 2-4 As shown, a reduction motor 33 is mounted on the top of one of the support frames 341, and the output end of the reduction motor 33 is fixedly connected to the rotating rod 34. A guide block 321 is fixedly connected to one side of the top of the rotating frame 32, and a track 31 is slidably connected to the inner side of the guide block 321. The top of the track 31 is fixedly connected to the bottom of the top plate 1. The top of one end of the rotating frame 32 is fixedly connected to the output end of the rotary motor 2. A nozzle 37 is mounted on one side of the top of the rotating rod 34, and the nozzle 37 is fixedly connected to an external water pipe.

[0030] The overall effect of this embodiment is that, driven by the rotary motor 2, the rotating frame 32 begins to rotate stably around its central axis. As a key transmission component, the rotating frame 32 moves synchronously with the guide block 321 mounted on it during rotation. The guide block 321 has a sliding contact surface that cooperates with the track 31. Under its traction, it can achieve continuous and smooth sliding movement along the arc-shaped path of the track 31, thereby driving the nozzle 37 mounted on the track 31 to move circumferentially around the storage tank, achieving full coverage of the outer circumference of the storage tank.

[0031] Simultaneously, driven by the geared motor 33, the high-speed rotation of the motor can be converted into a low-speed, high-torque output suitable for the lifting and lowering of the nozzle 37, thereby driving the rotating rod 34 connected to it to rotate vertically. The rotation of the rotating rod 34 will further drive the nozzle 37 to move up and down vertically, realizing the height adjustment function of the nozzle 37 based on circular motion, thus constructing a complete three-dimensional spray trajectory.

[0032] The spraying system controls the horizontal circular movement of the nozzle 37 via a rotary motor 2 and controls its vertical lifting via a geared motor 33. Under the coordinated control of the two, the nozzle 37 can achieve uniform spraying of the surface of the storage tank in all directions without dead angles, which significantly improves the uniformity of spraying and the efficiency of operation, and meets the high standard requirements of precise control and coverage effect for industrial cleaning, coating or cooling processes.

[0033] The device's operation and working principle are as follows: The rotating rod 34, driven by a power source, begins to rotate. Its driving groove 342 applies force to the force-bearing block 39, which then transmits this force to the moving frame 38. Simultaneously, the moving frame 38 moves, causing the sliding block 36 to move along the surface of the sliding rod 35. This sliding block 36 then moves the spray nozzle 37. Initially, the sliding block 36 moves downwards along the surface of the sliding rod 35. As the rotating rod 34 continues to rotate, the moving frame 38 and the force-bearing block 39 also continue to move downwards until the force-bearing block 39 reaches the end of the driving groove 342. From there, it begins to move in the opposite direction, causing the sliding block 36 to move upwards, thus improving the overall coverage of the spray during the spraying process. Simultaneously, the rotating frame 32 can rotate, achieving all-around spraying of the storage tank.

[0034] The rotary motor 2 drives the rotating frame 32 to rotate. At this time, the guide block 321 drives the surface of the track 31 to slide, thereby driving the nozzle 37 to make a circular motion. By using the drive of the geared motor 33, the rotating rod 34 can be rotated, thereby controlling the up and down movement of the nozzle 37 to achieve all-round spraying of the storage tank.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
