Description

Technical Field

[0001] This utility model relates to the field of oil storage tank processing, and to an oil storage tank surface coating device. Background Technology

[0002] In the surface treatment process of oil storage tanks, the most common methods are spraying and immersion. Immersion requires large immersion tanks, which places extremely high demands on space, and the immersion process is cumbersome, requiring the oil storage tanks to go through multiple steps such as hoisting and placing, immersion, and removal and draining, resulting in low production efficiency. In addition, the residual immersion solution inside the oil storage tank after immersion needs to be drained through the oil outlet, which is not only time-consuming but also easily leads to uneven coating, affecting the anti-rust and anti-corrosion effect. Existing spraying methods mostly rely on manual operation, requiring workers to manually spray the top, bottom, and sides of the oil storage tank. Among them, the side spraying area is the largest, and manual operation is not only labor-intensive and inefficient but also makes it difficult to ensure the uniformity and consistency of the coating, greatly increasing the burden on workers and wasting paint. Therefore, there is an urgent need for a device that can efficiently and stably complete the side coating spraying of oil storage tanks to improve production efficiency and reduce the labor intensity of workers.

[0020] The following is a description of the embodiments and appendices. Figures 1-2 The technical solution of this utility model will be further described below.

[0021] Example 1

[0022] An oil storage tank surface coating device includes: a base 1, a turntable 2, a rotating pressing component 3, a spraying component 4, and a lifting component 5;

[0023] The turntable 2 is rotatably mounted on the base 1 and has a power assembly 6 at its lower end that drives the turntable 2 to rotate. The turntable 2 is provided with an annular groove 21, which is used to limit the protruding edge at the bottom of the oil drum and to collect the coating liquid.

[0024] The rotating pressing component 3 is located above the turntable 2 and is rotatably mounted on the upper support 8. The rotating pressing component 3 fixes the oil drum on the turntable 2 by moving downward.

[0025] The spraying component 4 is disposed on one side of the oil drum and sprays a coating onto the side of the oil drum.

[0026] The lifting assembly 5 drives the nozzle 41 in the spraying assembly 4 to move up and down, and the spraying 41 is located inside the annular groove 21 in the projection direction.

[0027] As a further preferred embodiment, the bottom of the annular groove 21 is provided with a drain port 211, the bottom of the drain port 211 is provided with a drain pipe 212, the drain pipe 212 is provided with a control valve 213, and a collection device 7 is provided on one side of the base 1. The collection device 7 includes a connecting pipe 71, a filter 72 and a water pump 73. One side of the connecting pipe 71 is connected to the drain pipe 212 and the other side is connected to the filter 72. The water pump 73 is connected to the other side of the filter 72.

[0028] The drain outlet 211, drain pipe 212, and control valve 213 at the bottom of the annular tank 21, along with the collection device 7 (including connecting pipe 71, filter 72, and water pump 73) on one side of the base 1, constitute the paint recycling system. When the amount of paint collected in the annular tank 21 reaches a certain level, the control valve 213 is opened. Under the action of gravity, the paint flows through the drain outlet 211, drain pipe 212, and connecting pipe 71 into the filter 72. After the filter 72 filters out impurities in the paint, the water pump 73 transports the filtered paint to a storage container or back into the paint recycling system. This achieves paint recycling and reuse, reduces paint waste, lowers production costs, and avoids environmental pollution caused by indiscriminate paint discharge.

[0029] As a further preferred embodiment, the power assembly 6 includes a motor 61, a reducer 62, and a rotating shaft 63. The motor 61 and the reducer 62 are fixedly mounted on the base 1. The motor 61 is connected to the reducer 62 via a coupling. The output shaft of the reducer 62 is connected to the rotating shaft 63. The top end of the rotating shaft 63 is fixedly connected to the turntable 2. The top of the base 1 is provided with a ball bearing 11 to support the rotation of the turntable 2.

[0030] In a further preferred embodiment, the rotary pressing assembly 3 includes a second turntable 31, a cylinder 32, and a pressure plate 33. The second turntable 31 is rotatably mounted on the upper support 8 and supported by ball bearings inside the upper support 8. The cylinder 32 is fixed to the lower end of the second turntable 31, and the pressure plate 33 is fixed to the piston rod of the cylinder 32. In the rotary pressing assembly 3, the second turntable 31 is rotatably mounted on the upper support 8 via ball bearings, enabling rotation.

[0031] In a further preferred embodiment, the spraying assembly 4 also includes a paint storage tank 42, a paint pump 44, and a second filter 43. The paint storage tank 42 is fixed to the upper end of the upper support 8, and the paint pump 44 and the second filter 43 are fixed to the lower end of the upper support 8. The paint storage tank 42, paint pump 44, second filter 43, and spray head 41 are connected sequentially via pipes. In the spraying assembly 4, the paint storage tank 42 stores paint, and the paint pump 44 provides power for the paint delivery, drawing paint from the paint storage tank 42 and delivering it to the spray head 41 through pipes. The second filter 43 filters impurities in the paint, preventing impurities from clogging the spray head 41 and ensuring the normal operation of the spray head 41 and uniform paint spraying.

[0032] In a further preferred embodiment, the lifting assembly 5 includes a lifting guide rail 51, a lifting motor 52, a lead screw 53, a slider 54, and a guide seat 55. The lifting guide rail 51 and the lifting motor 52 are fixed on the guide seat 55. The lead screw 53 is rotatably mounted on the guide seat 55 and its upper end is connected to the output shaft of the lifting motor 52. The lead screw 53 is provided with a lead screw nut pair 56. The right side of the lead screw nut pair 56 is connected to the slider 54. The slider 54 is slidably mounted on the lifting guide rail 51, and its right end is connected to the nozzle 41 through a connecting bracket 56. The rotation of the lifting motor 52 drives the lead screw 53 to rotate. The lead screw nut pair 56 cooperates with the lead screw 53 to convert the rotational motion of the lead screw 53 into its own linear motion, thereby driving the slider 54 to slide up and down on the lifting guide rail 51. The slider 54 is connected to the nozzle 41 through the connecting bracket 57, thereby realizing the up and down movement of the nozzle 41 along the side of the oil drum.

[0033] like Figures 1-2 As shown, the working principle of this utility model is as follows:

[0034] The oil storage tank is placed in the annular groove 21 of the turntable 2. The annular groove 21 restricts the convex edge of the oil tank at the bottom, ensuring accurate positioning and preventing displacement during spraying that could affect the spraying effect. The rotating pressing assembly 3 is activated, and the cylinder 32 pushes the pressure plate 33 downward, firmly fixing the oil tank on the turntable 2 and preventing it from shaking during spraying. The motor 61 in the power assembly 6 drives the reducer 62 via a coupling. After the reducer 62 reduces the speed and increases the torque, it drives the rotating shaft 63 to rotate, thereby rotating the turntable 2 and the oil tank. Simultaneously, the lifting motor 52 in the lifting assembly 5 starts, driving the lead screw 53 to rotate. The lead screw nut pair 56 converts the rotational motion of the lead screw 53 into the vertical linear motion of the slider 54 on the lifting guide rail 51, thereby moving the spray nozzle 41 up and down along the side of the oil tank. The paint pump 44 in the spraying assembly 4 draws paint from the paint storage tank 42, filters impurities through the filter 43, and then delivers it to the nozzle 41. The nozzle 41 sprays the paint evenly onto the side of the rotating oil tank. Since the nozzle 41 is located inside the annular groove 21 in the projection direction, the paint dripping during the spraying process can be collected by the annular groove 21, avoiding paint pollution of the working environment and reducing paint waste.

[0035] The automated rotation, lifting, and spraying operations replace manual spraying of the sides of the oil storage tank, significantly improving spraying efficiency and reducing the labor intensity of workers. The annular trough effectively reduces paint waste and saves production costs by collecting the paint. At the same time, the device has a compact structure and lower site requirements, making it more advantageous than the immersion method.

[0036] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
