Description

Technical Field

[0001] This utility model relates to the field of tank cleaning technology, and in particular to a tank cleaning device. Background Technology

[0002] For liquor, liqueur, wine and related beverage products, during the production and storage process, there will be deposits of raw material components, filter leakage media (diatomaceous earth, activated carbon), impurities, etc. on the side walls and bottom of the tank. The deposit particles are small and easily adhere to the tank walls and bottom.

[0003] Chinese patent application CN214488192U, entitled "Wine Tank Cleaning System," includes a full-angle rotating washer installed inside the tank to be cleaned. This specialized full-angle rotating washer covers the inner wall of the tank, ensuring thorough cleaning without blind spots. Furthermore, the full-angle rotating washer does not use roller bearings, thus avoiding dry running, shedding of debris, or other contaminants while meeting tank cleaning requirements. It addresses, to some extent, the problem of incomplete cleaning of wine tanks in existing technologies. However, during the cleaning process, the full-angle rotating washer often has a large flow rate because it needs to clean the entire tank wall. The outlet at the bottom of the tank may not be able to discharge enough liquid, easily leading to liquid accumulation. This accumulation weakens the impact of the cleaning water on the bottom of the tank, reducing the cleaning effect. The full-angle rotating washer is generally located far from the bottom of the tank, and the gradual impact is further reduced by the accumulated liquid. Additionally, the presence of liquid causes impurities in the cleaning water to slowly settle and remain at the bottom of the tank. Therefore, in the current cleaning process, in order to ensure that even the impurities with strong adhesion to the bottom of the tank can be cleaned, it is still necessary to manually enter the tank for scrubbing, which is labor-intensive and poses certain safety hazards. Utility Model Content

[0004] To overcome the above-mentioned shortcomings of the prior art, the technical problem to be solved by this utility model is: how to avoid the sedimentation of impurities and better clean the bottom of the tank.

[0005] The technical solution adopted by this utility model to solve its technical problem is: The tank cleaning device includes a primary cleaning component located inside the tank. The tank has a wine outlet at the bottom and a bottom cleaning component located near the bottom inside the tank. The bottom cleaning component includes a coil located on the circumferential side of the tank near the bottom. The coil is connected to a power supply pipe that extends out of the tank. Multiple spray heads are spaced along the axial direction of the coil on the circumferential side near the bottom. The angle between the direction of fluid flow in any spray head and the direction of fluid flow in the coil corresponding to the point where the spray head connects to the coil is an acute angle.

[0006] Furthermore, the spray head includes a spray pipe connected to the coil, with the end of the spray pipe away from the coil being a flat end.

[0007] Furthermore, the flat end of the spray pipe is connected to a trumpet-shaped pipe, and the smaller diameter end of the trumpet-shaped pipe is fixedly connected to the flat end of the spray pipe.

[0008] Furthermore, the aforementioned coil is installed near the side wall of the tank via a first pipe support.

[0009] Furthermore, the number of the aforementioned bottom cleaning components is at least two sets, and multiple sets of bottom cleaning components are connected to the power supply pipe and are arranged at intervals along the central axis of the tank near the bottom of the tank.

[0010] Furthermore, the aforementioned tank is a conical bottom tank, and multiple of the aforementioned bottom cleaning components are located inside the conical bottom of the conical bottom tank. The diameter of the circular axis of the aforementioned coil is smaller the closer it is to the bottom of the conical bottom tank.

[0011] Furthermore, the aforementioned power supply pipe includes an inner pipe located inside the tank and an outer pipe located outside the tank, wherein the outer pipe is equipped with a first control valve.

[0012] Furthermore, the aforementioned inner pipe is installed near the side wall of the tank via multiple second pipe supports.

[0013] Furthermore, the aforementioned outer pipe includes a main pipe and a first unit pipe and a second unit pipe connected to the main pipe. The first control valve is located in the first unit pipe, and the second unit pipe is equipped with a second control valve.

[0014] Furthermore, the aforementioned primary cleaning component includes a cleaning pipe, one end of which is placed inside the tank and connected to a rotating nozzle, and the other end of which is connected to the aforementioned main control pipe. The aforementioned second unit pipe is connected to the aforementioned main control pipe. The aforementioned cleaning pipe is provided with a third control valve near the main control pipe, and the aforementioned main control pipe is provided with a fourth control valve.

[0015] The beneficial effects of this utility model are: The cleaning device is equipped with a primary cleaning component and a bottom cleaning component inside the tank. The bottom cleaning component uses a coil and spray heads. The spray heads are installed at an angle on the coil, so that the angle between the direction of fluid flow in any spray head 7 and the direction of fluid flow in the coil 5 corresponding to its connection point is an acute angle. This causes the fluid at the bottom of the tank to form a vortex, stirring the liquid at the bottom of the tank to prevent impurities from settling. This achieves the effect of cleaning water carrying impurities and discharging them through the bottom outlet of the tank, avoiding the accumulation of impurities at the bottom of the tank. Personnel no longer need to manually enter the bottom of the tank for cleaning, saving labor and achieving better cleaning results. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] First, it should be stated that the tank 1 mentioned in this application can be a wine tank, a vinegar tank, or a liquid pipe, or a tank 1 that contains powdered substances, chemicals, etc. and needs to be cleaned. The following uses a wine tank as an example.

[0020] like Figures 1-4 As shown, the tank 1 cleaning device includes a primary cleaning component 2 disposed within the tank 1. A wine outlet 3 is located at the bottom of the tank 1. A bottom cleaning component 4 is disposed near the bottom of the tank 1. The bottom cleaning component 4 includes a coil 5 disposed on the circumferential side of the tank 1 near the bottom. The coil 5 is connected to a power supply pipe 6 extending out of the tank 1. Multiple spray heads 7 are spaced apart along the axial direction of the coil 5 on its circumferential side near the bottom. The angle between the direction of fluid flow in any spray head 7 and the direction of fluid flow in the coil 5 corresponding to its connection point with the coil 5 is an acute angle. Preferably, the plane of the coil 5 is parallel to the plane of the bottom of the tank 1. Figure 3As shown, the arrows inside the coil 5 indicate the flow direction of the fluid (water or air) at the corresponding position inside the coil 5, and the arrows inside the spray head 7 indicate the flow direction of the fluid (water or air) at the corresponding position inside the spray head 7. Preferably, the angle between the flow direction of the fluid inside any spray head 7 and the flow direction of the fluid inside the coil 5 at the point where it connects to the coil 5 is 60 degrees. This design maximizes the vortex effect. The upper end face of the tank 1 is provided with a breather valve 24 and a first inlet 25. The tank 1 is provided with a magnetic float level gauge 27. The side wall of the tank 1 is provided with a second inlet 26. The circumferential side of the tank 1 near the bottom is provided with a sampling port with a valve. The breather valve 24 is used to prevent excessive pressure inside the tank 1 and to relieve pressure in emergencies; the first inlet 25 and the second inlet 26 are for personnel to enter the tank 1 during maintenance; the magnetic level gauge 27 (a level measuring instrument based on the principles of magnetic coupling and buoyancy) is used to monitor the liquid level in the tank on a daily basis; the sampling port with a valve is used to sample the liquid in the tank 1 on a daily basis; and the wine outlet 3 is also equipped with a corresponding valve, which is mainly used to discharge the wine in the tank 1 to the subsequent process section or to discharge the residue during cleaning.

[0021] When cleaning tank 1 is required, first connect the primary cleaning component 2 to the cleaning solution (preferably water), i.e., supply water to the primary cleaning component 2. Then, open the valve at the wine outlet 3 at the bottom of tank 1. Once preparation is complete, start the primary cleaning component 2. The primary cleaning component 2 cleans the entire tank, and the cleaning water and most of the residue are discharged through the wine outlet 3 at the bottom of tank 1. After the primary cleaning component 2 has cleaned the entire tank 1, stop the primary cleaning component 2 and supply water to the power supply pipe 6. The water flow through the power supply pipe 6 and the coil 5, via the spray head 7, achieves high-pressure impact cleaning of the tank bottom. Because the spray head 7 is tilted, and the angle between the direction of fluid flow in any spray head 7 and the direction of fluid flow in the coil 5 corresponding to its connection with the coil 5 is an acute angle, the water flow from multiple spray heads 7 can form a vortex-like flow of cleaning water. The residue at the bottom of tank 1 is carried along by the vortex-like water flow and is finally discharged through the wine outlet at the bottom of tank 1. It is worth noting that the power supply pipe 6 can also be connected to compressed air (compressed nitrogen can also be used, but compressed air is safer and less expensive). That is, after the overall cleaning of the tank is completed, if there is still a large amount of cleaning water to be drained inside the tank 1, the power supply pipe 6 can be connected to compressed air. The compressed gas flows through the power supply pipe 6 and the coil 5, impacting the bottom of the tank 1 through the spray head 7, achieving impact cleaning. Because the angle between the direction of fluid flow in any spray head 7 and the direction of fluid flow in the coil 5 corresponding to its connection with the coil 5 is acute, the gas sprayed from the spray head 7 can cause the residual cleaning water at the bottom of the tank 1 to rotate in a vortex, thereby causing the cleaning water and the mixture of impurities in the cleaning water to be discharged through the outlet 3 at the bottom of the tank 1. This design can agitate the cleaning water at the bottom of the tank 1 to create a vortex, thus preventing impurities in the cleaning water from settling and remaining at the bottom of the tank 1, avoiding impurity deposition. At the same time, the impact force of the fluid is greater than that of traditional cleaning mechanisms, which also improves the cleaning effect of the tank bottom to a certain extent.

[0022] The spray head 7 includes a spray pipe 28 connected to the coil 5, with the end of the spray pipe 28 away from the coil 5 being a flat end 8. The design of the flat end 8 allows the liquid sprayed from the spray pipe 28 to further increase the impact force, thereby enhancing the impact cleaning of the bottom of the tank 1 by the cleaning device.

[0023] The flat end 8 of the spray pipe 28 is connected to a trumpet-shaped pipe 9, and the smaller diameter end of the trumpet-shaped pipe 9 is fixedly connected to the flat end 8 of the spray pipe 28. The trumpet-shaped pipe 9 and the spray pipe 28 can be welded together. The design of the trumpet-shaped pipe 9 expands the spray area of ​​the flat-mouthed water jet. Combined with the design of the flat end of the spray pipe 28, this not only increases the impact force of the water flow, but also expands and increases the impact surface of the cleaning water on the bottom of the tank 1, further improving the cleaning effect.

[0024] The aforementioned coil 5 is mounted on the tank 1 near the side wall via a first pipe support 10. The first pipe support 10 is welded to the side wall of the tank 1, and the first pipe support 10 and the coil 5 are also welded together; this design can provide a certain degree of fixation for the coil 5, thereby ensuring the stability of the coil 5 to a certain extent.

[0025] The number of the aforementioned bottom cleaning components 4 is at least two sets, and all sets of bottom cleaning components 4 are connected to the power supply pipe 6 and are arranged at intervals along the central axis of the tank 1 near the bottom of the tank 1. This design can enhance the vortex effect of the cleaning water and improve the cleaning effect.

[0026] The aforementioned tank 1 is a conical-bottom tank, and multiple bottom cleaning components 4 are disposed within the conical bottom of the tank. The diameter of the circular axis of the coil 5 is smaller the closer it is to the bottom of the conical tank. Because the bottom of the tank is conical, the diameter of the circular axis of the coil 5 corresponding to the bottom cleaning component 4 is smaller the closer it is to the bottom. The bottom of the conical-bottom tank is relatively deep, and this design allows for excellent cleaning of the bottom of the tank.

[0027] The aforementioned power supply pipe 6 includes an inner pipe 11 located inside the tank 1 and an outer pipe 12 located outside the tank 1. The outer pipe 12 is equipped with a first control valve 17. This design allows the power supply pipe 6 to quickly cut off the water supply when connected to water, avoiding waste of water resources. Under normal circumstances, the power supply pipe 6 does not need to be disassembled from the water pipe, making it more convenient.

[0028] The inner pipe 11 is installed near the side wall of the tank 1 via multiple second pipe supports 13. Since the inner pipe 11 is frequently circulated with high-pressure liquid or gas, the installation of the second pipe supports 13 can stabilize the pipe to a certain extent.

[0029] The aforementioned outer pipe 12 includes a main pipe 14 and a first unit pipe 15 and a second unit pipe 16 connected to the main pipe 14. The first control valve 17 is located in the first unit pipe 15, and the second unit pipe 16 is equipped with a second control valve 18. In this design, the second unit pipe 16 is supplied with cleaning fluid (i.e., water), and the first unit pipe 15 is supplied with compressed air. When water is needed, the second control valve 18 opens; when compressed air is needed, the first control valve 17 opens. This design allows operators to more easily select the cleaning scheme for the cleaning device (i.e., whether to use gas or liquid, whether to utilize the cleaning water from the primary cleaning component 2, etc.). It is worth noting that the first control valve 17 and the second control valve 18 can be electrically controlled valves or manual valves; electrically controlled valves are also acceptable.

[0030] The aforementioned primary cleaning component 2 includes a cleaning pipe 19. One end of the cleaning pipe 19 is connected to a rotary nozzle 20 inside the tank 1, and the other end is connected to the main control pipe 21. The aforementioned second unit pipe 16 is connected to the aforementioned main control pipe 21. A third control valve 22 is provided on the cleaning pipe 19 near the main control pipe 21, and a fourth control valve 23 is provided on the main control pipe 21. When cleaning is required, the fourth control valve 23 on the main control pipe 21 is opened, and the third control valve 22 on the cleaning pipe 19 is activated. When the primary cleaning component 2 has completed its work and the bottom cleaning component 4 needs to work, the third control valve 22 is closed, and the second control valve 18 is opened. When the bottom cleaning component 4 has completed its work, the second control valve 18 is closed, and the fourth control valve is also closed. When compressed air is used during the operation of the bottom cleaning component 4, the first rotary nozzle 20 starts working. In summary, this application provides a tank cleaning device. The cleaning device can more thoroughly clean the tank 1. While cleaning the side walls of the tank 1, a bottom cleaning component 4 is added to the bottom of the tank 1. Spray heads 7 are installed on the coil 5. The angle between the direction of fluid flow in any spray head 7 and the direction of fluid flow in the coil 5 corresponding to its connection point with the coil 5 is an acute angle. This allows the fluid (compressed air or cleaning water) to pass through the spray head 7 at high speed and form a vortex-like flow, impacting the bottom of the tank and achieving the purpose of cleaning the bottom. Simultaneously, the liquid at the bottom of the tank 1 forms a vortex-like rotation, preventing impurity deposition and better cleaning the bottom of the tank 1.
