Description

Technical Field

[0001] This utility model relates to the field of fuel tank technology, specifically a skid-mounted fuel tank with a sewage discharge device. Background Technology

[0002] Oil storage tanks are containers for storing oil products and are the main equipment in oil depots. Oil storage tanks can be classified by material into metal tanks and non-metal tanks; by location into underground tanks, semi-underground tanks, and above-ground tanks; by installation method into vertical and horizontal tanks; and by shape into cylindrical, box-shaped, and spherical tanks.

[0003] According to CN219905514U, a sewage discharge device for a double-layer multi-compartment skid-mounted refueling tank is disclosed. This technology discloses a sewage discharge device for a double-layer multi-compartment skid-mounted refueling tank, including a tank body mechanism, a sewage discharge mechanism installed inside the tank body mechanism, the tank body mechanism including an outer tank body, an inner tank body fitted inside the outer tank body, and an oil inlet fixedly connected to the upper end of the inner tank body. It has the technical effect of "turning the threaded rod with a throttle, because one end of the support rod is slidably connected inside the inner tank body, thereby driving the threaded rod to move the threaded sleeve horizontally, the threaded sleeve driving the support rod and the annular brush to slide horizontally inside the inner tank body, the annular brush brushing out the impurities and dirt at the bottom of the inner tank body, and scraping the impurities, dirt and water to the sewage discharge port through the rear annular scraper, and discharging the dirt and water through the sewage discharge port, which is conducive to the sewage discharge and cleaning of the inner tank body. This structure allows the operator to clean and discharge the impurities, dirt and water at the bottom of the inner tank body from the outside."

[0004] In the above solution, the inner wall of the tank is cleaned directly by a ring scraper. However, the ring scraper is prone to wear and tear and gradually becomes damaged during continuous friction with the inner wall of the tank. This results in insufficient contact between the scraper and the inner wall of the tank. This insufficient contact directly weakens the cleaning effect, making it difficult for the cleanliness of the inner wall of the tank to meet the expected standard. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a skid-mounted refueling tank with a sewage discharge device. The device features a spring-loaded scraper that extends outwards, allowing the end of the scraper to remain in close contact with the inner wall of the tank as the moving assembly drives the scraping assembly. This ensures the scraper is tightly fitted to the tank's inner wall. Furthermore, it disperses friction and impact forces between the scraper and the tank's inner wall to some extent, helping to reduce wear on the scraper.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a skid-mounted refueling tank with a sewage discharge device, comprising a frame, a tank body fixed inside the frame, and a cleaning mechanism on the tank body for cleaning dirt residue inside the tank body. The cleaning mechanism includes:

[0007] The drive assembly includes a partition fixed in the middle of the frame, threaded rods rotatably mounted at the center of both sides of the partition, and the other end of the threaded rods rotatably mounted to the end of the frame.

[0008] The moving component includes a carriage threaded onto a threaded rod, and a ring fixed on the carriage;

[0009] The scraping assembly includes several arc-shaped shells fixed to the outer wall of the ring frame, an arc-shaped scraper that is slidably installed inside the arc-shaped shells, and several spring plates installed inside the arc-shaped shells.

[0010] Preferably, the scraping assembly further includes several limiting rods fixed inside the arc-shaped shell, and the limiting rods are located at the ends of the spring sheet.

[0011] Preferably, the moving component further includes a wave deflector fixed to one end of the ring frame, and the wave deflector has a circular hole in the center of its interior.

[0012] Preferably, the movable component further includes a plurality of support frames fixed inside the ring frame, and the support frames are fixed between the ring frame and the slide.

[0013] Preferably, the drive assembly further includes guide rails fixed to both ends of the inner wall of the tank, and the end of the carriage is slidably installed inside the guide rails.

[0014] Preferably, the drive assembly further includes a geared motor installed on the outer wall at both ends of the tank, and the output end of the geared motor is fixed to the threaded rod. Beneficial effects

[0015] This invention provides a skid-mounted refueling tank with a sewage discharge device. Compared with the prior art, it has the following advantages:

[0016] (1) The pressure of the spring plate pushes the arc-shaped scraper to extend outward, so that when the moving component drives the scraping component to move, the end of the arc-shaped scraper can always be in contact with the inner wall of the tank, which can ensure that the arc-shaped scraper is in close contact with the inner wall of the tank; and it can also disperse the friction and impact between the arc-shaped scraper and the inner wall of the tank to a certain extent, which helps to reduce the wear of the arc-shaped scraper.

[0017] (2) Limit the spring sheet by the limiting rod to prevent the arc scraper from shifting position when it is squeezed or rebounds; when the tank is in daily use, the moving component stops moving so that the baffle plate reduces the impact caused by the oil sloshing.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a skid-mounted refueling tank with a sewage discharge device, including a frame 1, a tank 2 fixed inside the frame 1, and a cleaning mechanism 3 provided on the tank 2 for cleaning dirt residue inside the tank 2. The cleaning mechanism 3 includes:

[0025] The drive assembly 31 includes a partition 311 fixed in the middle of the inside of the frame 1, and threaded rods 312 rotatably mounted on the center of both sides of the partition 311, with the other end of the threaded rods 312 rotatably mounted to the end of the frame 1.

[0026] The movable component 32 includes a carriage 321 threadedly mounted on a threaded rod 312, and a ring 322 fixed on the carriage 321;

[0027] The scraping assembly 33 includes several arc-shaped shells 331 fixed to the outer wall of the ring frame 322, an arc-shaped scraper 332 slidably installed inside the arc-shaped shells 331, and several spring plates 333 installed inside the arc-shaped shells 331.

[0028] In this embodiment, the pressure of the spring plate 333 pushing the arc-shaped scraper 332 outward extends the moving component 32 to drive the scraping component 33 to move. This ensures that the end of the arc-shaped scraper 332 is always in contact with the inner wall of the tank 2, thus ensuring that the arc-shaped scraper 332 is in close contact with the inner wall of the tank. Furthermore, it can also disperse the friction and impact between the arc-shaped scraper 332 and the inner wall of the tank 2 to a certain extent, which helps to reduce the wear on the arc-shaped scraper 332.

[0029] Specifically, the scraping assembly 33 also includes several limiting rods 334 fixed inside the arc-shaped shell 331, and the limiting rods 334 are located at the ends of the spring sheet 333.

[0030] In this embodiment, the spring sheet 333 is limited by the limiting rod 334 to prevent the arc-shaped scraper 332 from shifting position when it is squeezed or rebounds.

[0031] Specifically, the moving component 32 also includes a wave deflector 323 fixed to one end of the ring frame 322, and the wave deflector 323 has a round hole in the center of its interior.

[0032] In this embodiment, when the tank 2 is in daily use, the moving component 32 is kept stationary, so that the anti-sloshing plate 323 reduces the impact caused by the sloshing of oil.

[0033] Specifically, the moving component 32 also includes a number of support frames 324 fixed inside the ring frame 322, and the support frames 324 are fixed between the ring frame 322 and the slide 321.

[0034] In this embodiment, the support frame 324 can improve the overall strength of the moving component 32 and prevent it from easily deforming under stress.

[0035] Specifically, the drive assembly 31 also includes guide rails 313 fixed to both ends of the inner wall of the tank 2, and the end of the slide 321 is slidably installed inside the guide rails 313. A reduction motor 314 is installed on the outer wall of both ends of the tank 2, and the output end of the reduction motor 314 is fixed to the threaded rod 312.

[0036] In this embodiment, the output end of the geared motor 314 drives the threaded rod 312 to rotate, and with the cooperation of the guide rail 313, it drives the moving component 32 to move horizontally, so that the moving component 32 scrapes off the dirt residue on the inner wall of the tank 2 through the scraping component 33.

[0037] The working principle and usage process of this utility model are as follows: First, the output end of the geared motor 314 drives the threaded rod 312 to rotate, and with the cooperation of the guide rail 313, it drives the moving component 32 to move horizontally. At the same time, the moving component 32 drives the scraping component 33 to scrape away the dirt residue on the inner wall of the tank 2. Furthermore, the pressure of the spring plate 333 pushes the arc-shaped scraper 332 to extend outward, so that the end of the arc-shaped scraper 332 can always be in contact with the inner wall of the tank 2, which can ensure that the arc-shaped scraper 332 is in close contact with the inner wall of the tank. In addition, it can also disperse the friction and impact force between the arc-shaped scraper 332 and the inner wall of the tank 2 to a certain extent, which helps to reduce the wear of the arc-shaped scraper 332.
