Description

Technical Field

[0001] This utility model relates to the field of petroleum pressure vessels, specifically an automatic cleaning device for horizontal petroleum pressure vessels. Background Technology

[0002] Oil pressure vessels are pressure vessels used for storing and processing oil and petroleum products. Compared to vertical pressure vessels, horizontal pressure vessels are more common for storing and transporting oil and petroleum products, offering a wider range of applications and more advantages. During storage and transportation, oil stains, residues, and corrosion products can easily accumulate inside the pressure vessel. Therefore, cleaning oil pressure vessels is crucial for ensuring their safe and reliable operation.

[0003] For example, Chinese invention patent CN118514986B, published on October 1, 2024, discloses a horizontal pressure vessel for petrochemicals, comprising: a vessel body, on which a feeding structure is provided, the feeding structure including: a main feeding pipe and a secondary feeding pipe, the main feeding pipe and the secondary feeding pipe being respectively located at the top of both ends of the vessel body; a partition plate; and an internal cleaning assembly. This horizontal pressure vessel for petrochemicals, through the arrangement of the feeding structure, partition plate, and position adjustment assembly, possesses excellent flexibility. It can adapt to different operating conditions and material requirements, allowing the internal space allocation of the vessel to be adjusted as needed to meet changing demands during production. The arrangement of the internal cleaning assembly and the movement of the partition plate enable continuous spray cleaning of the internal walls and partition plate of the vessel. This helps prevent the accumulation of material residue and contaminants, maintains the cleanliness of the vessel interior, and ensures product quality and production safety.

[0004] As can be seen from the above patents, the internal cleaning component of the horizontal pressure vessel can only spray and clean the internal wall of the pressure vessel, but cannot brush and wash the contaminants on the internal wall of the pressure vessel, which easily leads to incomplete and inadequate cleaning; therefore, the cleaning structure needs to be redesigned to improve it.

[0029] Reference Figure 1The present invention discloses an automatic cleaning device for a horizontal oil pressure vessel, comprising a fixed component 1, a driving component 2, a rotating component 3, a cleaning component 4, a control unit 5, and a cleaning fluid inlet 6.

[0030] The fixing component 1 includes a fixing base 11 and a fixing ring 12. The fixing ring 12 is fixed after being inserted into the opening end of the pressure vessel. The fixing base 11 is fixedly connected to the fixing ring 12 and is tightened by hexagonal screws through the internal hexagonal holes on the edge of the fixing base 11 and the internal screws on the flange face of the opening end of the pressure vessel, thereby strengthening the connection between the fixing base 11 and the pressure vessel.

[0031] The drive assembly 2 includes a drive component 21 and a guide follower 22. The drive component 21 is fixed on the fixed base 11. The drive component 21 can adopt a structure in which a drive motor and a gear cooperate. The drive component 21 is used to drive the guide follower 22 to move in the horizontal direction. The guide follower 22 is rotatably connected to and passes through the center of the fixed base 11. The guide follower 22 can be in the form of a toothed groove. The drive component 21 and the guide follower 22 are connected by a gear and toothed groove meshing connection. The drive motor of the drive component 21 drives the gear, which in turn drives the toothed groove, and finally drives the guide follower 22 to move in the horizontal direction.

The fixed base 31 is connected to the guide follower 22 and can be pushed by the guide follower 22 to move horizontally inside the pressure vessel. The motor 32 is fixed to the fixed base 31 and is used to drive the rack 34 to rotate. The rotating fixed base 33 is connected to the fixed base 31 and is used to fix and guide the rack 34 to rotate. The rack 34 rotates... The guide rod 35 is connected to and passes through the center of the rotating fixed seat 33 to the guide groove 37; the slip ring 35 and the drive adjustment member 36 are disposed on the rack 34 and located between the rotating fixed seat 33 and the guide groove 37, and the drive adjustment member 36 is used to drive the slip ring 35 to move on the rack 34; the guide groove 37 is used to limit the sliding direction of the slide rod 38, and the slide rod 38 is sleeved in the guide groove 37; the two ends of the connecting rod 39 are rotatably connected to the outer ends of the slip ring 35 and the slide rod 38, respectively, and the connecting rod 39 is used to drive the slide rod 38 to open outward or retract inward.

[0033] Reference Figure 3The cleaning assembly 4 includes a cleaning ring 41, which is set and sleeved on the outer end of the slide bar 38. Several sensors 42, nozzles 43 and steel brushes 44 are sequentially arranged on the outer circumference of the cleaning ring 41. The sensors 42 are used to monitor the distance between the cleaning ring 41 and the inner wall of the pressure vessel, and then adjust the movement of the rack 34 to adjust the opening length of the slide bar 38 to ensure that the steel brushes 44 are tightly attached to the inner wall of the pressure vessel. Moreover, it can be adjusted according to the change of the inner diameter of the pressure vessel to adapt to the change of the inner diameter from the middle to both ends of the pressure vessel. The nozzles 43 are used to spray cleaning fluid onto the inner wall of the pressure vessel, and the steel brushes 44, which are tightly attached to the inner wall of the pressure vessel, are used to scrub the inner wall of the pressure vessel after the cleaning fluid is sprayed.

[0034] In an optional embodiment, a control unit 5 is provided at the top edge of the fixed base 11. The control unit 5 is electrically connected to the drive assembly 2, the motor 32, and the sensor 42. It can control the guide follower 22 to push the fixed base 31, and can control the movement of the rack 34 and the drive adjustment member 36 to drive the connecting rod 39 to move, thereby driving the slide rod 38 to open outward or retract inward, so that the steel brush 44 fits tightly against the inner wall of the pressure vessel.

[0035] In an optional embodiment, a cleaning fluid inlet 6 is provided at the top of the shaft of the guide follower 22. The cleaning fluid delivery pipe is inserted from the cleaning fluid inlet 6, passing sequentially through the shaft of the guide follower 22, the center of the fixed seat 31, and the hollow shaft of the rack 34 to the guide groove 37. A three-way valve is connected at the guide groove 37. The cleaning fluid first enters the guide groove 37 through the cleaning fluid delivery pipe from the cleaning fluid inlet 6, and then is stored in the guide grooves 37 on both sides through the three-way valve. Then, it is delivered to the nozzle 43 on the outer end of the cleaning ring 41 through the center of the slide rod 38.

[0036] The installation and operation process of this application is as follows:

[0037] Before using this application, installation is required. First, open the top end cap of the horizontal oil pressure vessel, then install the cleaning component 4 on the rotating component 3 of the closed slide bar 38. The rotating component 3 is installed on the fixed component 1, and then the fixing ring 12 is inserted into the opening end of the pressure vessel for initial fixation. Then, the fixing base 11 is tightened on the flange surface of the opening end of the pressure vessel with hexagonal screws for reinforcement fixation. Then, the drive component 2 is installed on the fixed component 1, and the cleaning fluid delivery pipe is connected before the cleaning work can begin.

[0038] When control unit 5 is activated, both motor 32 and sensor 42 are turned on. Motor 32 drives rack 34 and drive adjusting member 36 to move to the left. The rotation of rack 34 drives slide rod 38 to rotate, which in turn drives connecting rod 39 to move to the left, causing slide rod 38 to open outward within guide groove 37. When sensor 42 detects that the distance to the inner wall of the pressure vessel is equal to the length of steel brush 44, it sends a signal to control unit 5, which then stops driving adjusting member 36 to move. At this point, steel brush 44 is tightly fitted against the inner wall of the pressure vessel. Cleaning fluid is then supplied from cleaning fluid delivery pipe. The cleaning fluid is fed into the guide channel 37 and then delivered to the nozzle 43 to begin spraying cleaning fluid onto the inner wall of the pressure vessel. Simultaneously, the rotating slide bar 38 drives the cleaning assembly 4 to rotate, and the rotating steel brush 44 scrubs the inner wall of the pressure vessel after the cleaning fluid has been sprayed. The steel brush 44 not only cleans the inner wall of the pressure vessel in the rotational direction but also performs horizontal scrubbing due to the leftward movement of the rack 34. The control unit 5 also controls the drive assembly 2 to move to the left, thereby pushing the rotating assembly 3 and the cleaning assembly 4 to the left, also causing the steel brush 44 to perform horizontal scrubbing. When the cleaning reaches the end of the pressure vessel, the inner diameter of the pressure vessel decreases. The sensor 42 detects the decrease in distance and transmits a signal to the control unit 5. The control unit 5 controls the drive adjustment component 36 to move to the right, causing the slide bar 38 to retract inward, so that the steel brush 44 also fits tightly against the inner wall of the pressure vessel to adapt to the change in the inner diameter of the pressure vessel.

[0039] Of course, the embodiments described in this specific implementation are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
