Description

Technical Field

[0001] This utility model relates to the field of fluid food production technology, and more specifically, to a tank cleaning system and fluid food production equipment having the tank cleaning system. Background Technology

[0002] In the production of fluid foods, various types of tanks are usually required to store materials, and agitators are installed inside the tanks to meet various process requirements.

[0003] The tank cleaning system in related technologies involves installing multiple spray balls inside the tank, one for cleaning the tank body and the other for cleaning the agitator. The cleaning fluid delivery pipe connects to the spray balls via branches of varying diameters. The diameter of the tank body branch of the spray ball cleaning the tank is larger than the diameter of the agitator branch of the spray ball cleaning the agitator. For highly viscous materials such as dairy products, the strong adhesion requires a higher outlet water pressure to ensure cleaning effectiveness. However, due to the different branch pipe diameters, when the pressure meets the requirements of the tank body branch, it leads to excessive pressure in the agitator branch. This causes the sprayed cleaning fluid to atomize instantaneously, reducing the spraying mechanical force. Furthermore, the atomized cleaning force is not concentrated, resulting in dispersed impact and low normal stress and shear force on the residual material, leading to poor cleaning results.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] The tank cleaning system 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0029] like Figures 1-3 As shown, the tank cleaning system 1 according to an embodiment of the present invention includes a main water supply line 10, a first spray device 20, a second spray device 30, a first branch line 40, a second branch line 50, and a switching device.

[0030] The first branch line 40 is connected to the main water supply line 10 and the first sprinkler device 20. The second branch line 50 is connected to the main water supply line 10 and the second sprinkler device 30. The inner diameter of the first branch line 40 is larger than the inner diameter of the second branch line 50. The switching device can switch between a first state and a second state. In the first state, the switching device connects the main water supply line 10 and the first branch line 40 and disconnects the main water supply line 10 and the second branch line 50. In the second state, the switching device connects the main water supply line 10 and the second branch line 50 and disconnects the main water supply line 10 and the first branch line 40.

[0031] Specifically, when the first spray device 20 is cleaning, the switching device switches to the first state, connecting the main water supply line 10 and the first branch line 40 and disconnecting the main water supply line 10 and the second branch line 50. The first spray device 20 sprays while the second spray device 30 does not spray. When the second spray device 30 is cleaning, the switching device switches to the second state, connecting the main water supply line 10 and the second branch line 50 and disconnecting the main water supply line 10 and the first branch line 40. The second spray device 30 sprays while the first spray device 20 does not spray.

[0032] For example, the cleaning fluid circulation within the main water supply line 10 may include alkaline and acidic circulation. During the 900-second alkaline circulation, the switching device remains in the first state for 150 seconds at a flow rate of 12 tons every 180 seconds, then switches to the second state and remains there for 30 seconds at a flow rate of 5 tons. In other words, the first spray device 20 sprays for 150 seconds every 180 seconds, and after the first spray device 20 is turned off, the second spray device 30 sprays for 30 seconds. The same method is used during the 600-second acidic circulation.

[0033] Since the main water supply line 10 is connected to only one of the first branch line 40 and the second branch line 50 at any given time, compared to the method of multiple spray devices cleaning simultaneously in related technologies, the water in the main water supply line 10 is not diverted by multiple branches. The main water supply line 10 can maintain the outlet pressure of the first spray device 20 even with a relatively low water pressure. Therefore, when the switching device switches to the second state, the lower water pressure in the main water supply line 10 will not cause the outlet pressure of the second spray device 30 to be too high, preventing the cleaning fluid of the second spray device 30 from atomizing due to excessive pressure, thus avoiding a reduction in cleaning effect caused by atomization.

[0034] The water pressure of the main water supply line 10 can be greater than or equal to the water pressure requirement of the first spray device 20 and less than the atomization pressure of the second spray device 30.

[0035] The main water supply line 10 can also use different water pressures when the switching device switches to different states. For example, the main water supply line 10 uses a larger water pressure in the first state and a smaller water pressure in the second state.

[0036] According to the tank cleaning system 1 of this utility model embodiment, by setting the switching device, the switching device can be switched between a first state and a second state. In the first state, the switching device connects the main water supply line 10 and the first branch line 40 and disconnects the main water supply line 10 and the second branch line 50. In the second state, the switching device connects the main water supply line 10 and the second branch line 50 and disconnects the main water supply line 10 and the first branch line 40. In this way, the main water supply line 10 is only connected to one of the first branch line 40 and the second branch line 50 at any given time. Compared with the method of multiple spray devices cleaning simultaneously in related technologies, the water in the main water supply line 10 is not diverted by multiple branches, and the water pressure of the main water supply line 10 can ensure the outlet water pressure of the first spray device 20 even with a smaller water pressure. Therefore, by controlling the water pressure of the main water supply line 10 to make it lower than the atomizing water pressure of the second spray device 30, or by using different water pressures when the first spray device 20 and the second spray device 30 spray separately, it is possible to avoid the outlet water pressure of the second spray device 30 being too high, to avoid the cleaning liquid of the second spray device 30 atomizing due to excessive pressure, and to avoid the cleaning effect being reduced due to atomization of the cleaning liquid.

[0037] Furthermore, by setting up the switching device, the main water supply line 10 is connected to only one of the first branch line 40 and the second branch line 50 at any given time. Compared with the method of multiple spray devices cleaning at the same time in related technologies, this can reduce the consumption of cleaning fluid and save cleaning costs.

[0038] Therefore, the tank cleaning system 1 according to the present invention can avoid the atomization of the cleaning fluid and has the advantages of good cleaning effect and low cleaning cost.

[0039] The tank cleaning system 1 according to a specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0040] In some specific embodiments of this utility model, such as Figures 1-3 As shown, the tank cleaning system 1 according to an embodiment of the present invention includes a main water supply line 10, a first spray device 20, a second spray device 30, a first branch line 40, a second branch line 50, and a switching device.

[0041] Specifically, such as Figure 2 and Figure 3 As shown, both the first spray device 20 and the second spray device 30 are spray balls. This allows for comprehensive spray cleaning of the tank interior through the rotation of the spray balls.

[0042] More specifically, such as Figure 2 and Figure 3 As shown, the second spray device 30 is provided with multiple elongated spray nozzles. These nozzles include a main spray nozzle 31 and multiple auxiliary spray nozzles 32 located on either side of the main spray nozzle 31. The width of the main spray nozzle 31 is greater than the width of the auxiliary spray nozzles 32. This reduces the pressure at the main spray nozzle 31 while ensuring sufficient water flow, preventing excessive pressure at the main spray nozzle 31 from causing atomization of the cleaning fluid.

[0043] Advantageously, the width of the main spray nozzle 31 is 1.5-2.5 times the width of the secondary spray nozzle 32. Preferably, the width of the main spray nozzle 31 is twice the width of the secondary spray nozzle 32. This further facilitates reducing the pressure at the main spray nozzle 31 while ensuring the water flow rate, and further avoids excessive pressure at the main spray nozzle 31 that could lead to atomization of the cleaning fluid.

[0044] More advantageously, the width of the main spray nozzle 31 is 2.5-3.5 mm. Preferably, the width of the main spray nozzle 31 is 3 mm. Specifically, the width of the secondary spray nozzle 32 is 1.5 mm. This facilitates control of the width of the main spray nozzle 31, reducing the pressure at the main spray nozzle 31 while ensuring the water flow rate, and further preventing excessive pressure at the main spray nozzle 31 from causing atomization of the cleaning fluid.

[0045] Specifically, the spray nozzle of the first spray device 20 can also be elongated and can include a main spray nozzle and a secondary spray nozzle. The width of the main spray nozzle is greater than the width of the secondary spray nozzle, so as to control the water pressure of the first spray device 20.

[0046] Optionally, such as Figure 1As shown, the first spray device 20 is installed inside the storage tank and is suitable for cleaning the tank body 2. The second spray device 30 is installed inside the storage tank and is suitable for cleaning the agitator 3. This allows the first branch 40 connected to the first spray device 20 for cleaning the tank body to have a larger pipe diameter than the second branch 50 connected to the second spray device 30 for cleaning the agitator 3, ensuring that the water flow rate of the first spray device 20 for cleaning the tank body 2 is greater than that of the second spray device 30 for cleaning the agitator 3. Since cleaning the tank body 2 requires a larger water flow rate than cleaning the agitator 3, it facilitates water flow distribution and improves the cleaning effect on both the tank body 2 and the agitator 3.

[0047] Furthermore, the nominal diameter of the first branch 40 is DN65, and the nominal diameter of the second branch 50 is DN25. This facilitates the distribution of water flow between the first spray device 20 and the second spray device 30, thereby improving the cleaning effect on the tank 2 and the agitator 3.

[0048] Figure 1 A tank cleaning system 1 according to some examples of the present invention is shown. For example... Figure 1 As shown, the switching device includes a first on / off valve 61 and a second on / off valve 62. The first on / off valve 61 is located on the first branch 40. The second on / off valve 62 is located on the second branch 50. Specifically, in the first state, the first on / off valve 61 is open and the second on / off valve 62 is open; in the second state, the second on / off valve 62 is open and the first on / off valve 61 is closed. This allows the first on / off valve 61 and the second on / off valve 62 to control the on / off of the first branch 40 and the second branch 50, respectively, thus achieving on / off control between the main water supply line 10 and the first branch 40 and the second branch 50.
