Description

Technical Field

[0001] The utility model relates to the technical field of storage tank cleaning, in particular to a high-efficiency storage tank cleaning device. Background Art

[0002] After a period of use, storage tanks may sometimes experience scaling due to the physical and chemical properties of the materials they contain, or the materials in the tank may need to be replaced, necessitating the use of a tank cleaning device. Most commercially available tank cleaning devices are single-point cleaning devices, meaning that a set of cleaning devices can only clean a specific storage tank; otherwise, manual operation is required to complete the cleaning process.

[0003] Chinese utility model patent publication number CN218775330U discloses a cleaning device for petrochemical tanks. The key technical feature of this patent is the integration of a cleaning nozzle with a cantilever frame. This allows the nozzle to be adjusted to the desired position as needed during use, eliminating the need for repeated disassembly of the frame and effectively improving tank cleaning efficiency. However, manual adjustment of the sliding element is required for each cleaning operation, which is inconvenient. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a tank cleaning device to achieve continuous cleaning of multi-station tanks.

The transverse guide rail is connected to a guide rail motor, which is connected to a PLC controller via an electrical circuit. A removable photoelectric switch is mounted on the transverse guide rail. When the photoelectric switch detects the movable device, it sends a signal to the PLC controller, which stops the guide rail motor for a preset period of time.

[0010] In order to prevent the moving device from separating from the two ends of the transverse guide rail during movement, the technical solution provided by the utility model includes: setting limit members at both ends of the transverse guide rail, and setting a limit block adapted to the limit members on the moving device.

[0011] In order to improve the cleaning effect, the technical solution provided by the utility model includes: the nozzle is a rotating nozzle.

[0012] The advantages and beneficial effects of the utility model are:

[0023] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0024] Example

[0025] See also Figures 1 to 4 A high-efficiency tank cleaning device includes a transverse frame 1 and a transverse guide rail 2 fixedly mounted on the transverse frame 1. The transverse guide rail 2 is slidably connected to a moving device 3. The moving device 3 includes a grooved retractable wheel 4. The grooved retractable wheel 4 is arranged below the transverse guide rail 2. A water inlet pipe 5 passes through the transverse frame 1 and the grooved retractable wheel 4 to form a water outlet pipe 6. The end of the water outlet pipe 6 is connected to a nozzle 7, which is engaged with the grooved retractable wheel 4. The sliding of the moving device 3 on the transverse guide rail 2 changes the transverse position of the nozzle 7. The rotation of the grooved retractable wheel 4 drives the water outlet pipe 6 to rotate to complete the retraction action, thereby changing the height of the nozzle 7. The nozzle 7 is a rotating nozzle that can achieve a 360-degree cleaning operation inside the tank.

[0026] The transverse guide rail 2 is connected to the guide rail motor 8, and the guide rail motor 8 is connected to the PLC controller (not shown in the figure) through a circuit. A detachable photoelectric switch 9 is provided on the transverse guide rail 2. After the photoelectric switch 9 detects the moving device 3 sliding on the transverse guide rail 2, it will send a signal to the PLC controller. The PLC controller controls the guide rail motor 8 to stop for a preset time period. After the preset time period, the guide rail motor 8 continues to rotate.

[0027] The rotating shaft of the grooved retractable wheel 4 is connected to the retractable motor 10, and the retractable motor 10 is connected to the PLC controller through the circuit. The PLC controller controls the rotation of the retractable motor 10 to further control the rotation of the grooved retractable wheel 4, reeling the water outlet pipe 6, and then controlling the height of the nozzle 7.

[0028] A drag chain 11 is provided on the outside of the water inlet pipe 5, and one end of the drag chain 11 is fixedly connected to the moving device 3. The movement of the moving device 3 on the transverse guide rail 2 will drive the water inlet pipe 5 to move together. During long-term operation, the water pipe will rub against the transverse frame 1 and cause damage. Arranging a drag chain on the outside of the water inlet pipe 5 can protect the water pipe and increase the service life of the cleaning device.

[0029] Limiting members 12 are provided at both ends of the transverse guide rail 2, and limiting blocks 13 adapted to the limiting members 12 are provided on the moving device 3. When the moving device 3 moves back and forth along the transverse guide rail 2 to the two ends of the transverse frame 1, it is possible that it will fall off from both ends. A limiting structure is provided to avoid the above unnecessary risks.

[0030] Working Principle: First, based on the actual situation at the work site, the location of the tanks to be cleaned and the height of the cleaning operation are determined. Several tanks to be cleaned are then placed below the high-efficiency tank cleaning device along the working direction of the transverse guide rail 2. Removable photoelectric switches 9 are installed on the transverse guide rail 2 according to the number and location of the tanks to be cleaned. The forward and reverse rotation times of the reciprocating motor 10 are set via a PLC controller based on the height of the cleaning operation. Based on the difficulty of the tank cleaning, a preset time period is set in the PLC controller. This time period is the time after the photoelectric switch detects the moving device 3 and the PLC receives a signal to stop the guide motor. During use, water enters the water inlet pipe 5, and the moving device 3 is driven by the guide rail motor 8 to move toward the other end of the transverse guide rail 2. When the photoelectric switch 9 detects the moving device 3, it sends a signal to the PLC controller. The PLC controller stops the guide rail motor 8 for a preset time period. At the same time, the retractable discharge motor 10 rotates forward, the water outlet pipe 6 discharges water, and the nozzle 7 moves downward and sprays water to clean the inside of the storage tank. After reaching the set value, the retractable discharge motor 10 reverses. After a certain number of cycles, that is, repeated cleaning for a period of time, the grooved retractable wheel 4 retracts the water outlet pipe 6, the retractable discharge motor 10 stops, and the guide rail motor 8 stops and works again after reaching the preset time period. Repeat the above steps to complete the cleaning of several storage tanks. Finally, the limit block 13 of the moving device 3 and the limit member 12 of the transverse guide rail 2 complete the limit. It can be understood that the moving device 3 can start the above work from any position of the transverse guide rail 2.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
