Description

Technical Field

[0001] The utility model belongs to the technical field of fermentation tank cleaning equipment, and in particular relates to a cleaning nozzle suitable for a container containing a heat exchange coil. Background Art

[0002] When it comes to cleaning the interior of a container, you will usually encounter a container that contains a heat exchange coil (usually a spiral type), such as a fermentation tank. The heat exchange tube bundle is generally attached to the inner wall of the container, and the height is two-thirds of the cylinder part of the container (usually including the cylinder and the heads at both ends). For this, a special cleaning nozzle is required.

[0003] In the prior art, the cleaning nozzles used for cleaning containers containing heat exchange coils usually use three-dimensional nozzles, whose nozzles can realize horizontal and vertical rotation. During the cleaning process of containers containing heat exchange coils, such nozzles need to be placed between the spiral circles of the heat exchange coils and move along the spiral direction of the heat exchange coils to ensure the coverage of the heat exchange coils. The cleaning speed is slow, the efficiency is low, a large amount of cleaning liquid is required, and the practicality is poor. In addition, the operating port at the top of the container is small, which also has great limitations in operation. Utility Model Content

Among them, the connecting pipe 10 has a tube cavity 11 with one end being blocked, and a water outlet connected to the tube cavity 11 is provided on the side wall of the connecting pipe 10, and an impeller 60 is provided in the tube cavity 11. The rotating sleeve 20 is sleeved on the connecting pipe 10 and is rotatably connected to the connecting pipe 10 through a bearing 50. There are multiple spray structures 30, and each spray structure 30 is arranged on the rotating sleeve 20 at an annular interval around the axis of the rotating sleeve 20, and is connected to the water outlet, and each spray structure 30 has a nozzle portion that can be pitched and rotated. The driving structure 40 is arranged on the connecting pipe 10, which can drive the impeller 60 to rotate and drive the rotating sleeve 20 to rotate at the same time.

[0031] The cleaning nozzle suitable for a container containing a heat exchange coil provided in this embodiment has the following usage principle: the connecting pipe 10 can be connected to the liquid supply (cleaning liquid) pipeline, and a rigid pipe is usually provided, which is connected to the connecting pipe 10 through the rigid pipe, and then the cleaning nozzle suitable for a container containing a heat exchange coil provided in this embodiment is extended into the container through the operation port through the rigid pipe. During the cleaning process, it is only necessary to adjust the pitch angle of each nozzle part in advance, and then through the vertical movement of the rigid pipe, the driving structure 40 can simultaneously drive the impeller 60 and the rotating sleeve 20 to rotate, ensure the water supply pressure, and ensure that the rotating sleeve 20 drives each injection structure 30 to rotate, so as to realize the cleaning of the inside of the container, of course including the cleaning of the heat exchange coil. Specifically, each nozzle part can flush the top of the heat exchange coil (spiral coil) after the pitch is rotated downward, and can flush the bottom of the heat exchange coil (spiral coil) after the pitch is rotated upward.

[0032] The cleaning nozzle suitable for a container containing a heat exchange coil provided in this embodiment is, compared with the prior art, arranged in an annular interval around the axis of the rotating sleeve 20, that is, each spray structure 30 is driven by the rotating sleeve 20 to rotate, and the cleaning liquid can cover the entire container space during the process of the connecting pipe 10 being placed vertically and moving vertically. Moreover, with the pitch rotation adjustment of each nozzle part, the direction of the sprayed cleaning liquid can be changed, and then it can correspond to the top and bottom of each spiral ring in the heat exchange coil, ensuring the cleaning effect of the heat exchange coil. This method can improve the cleaning efficiency, reduce the amount of cleaning liquid, and can also adapt to the operation port, which is convenient to operate and highly practical.

[0033] In some embodiments, the bearing 50 may be Figure 1 See the structure shown. Figure 1There are two bearings 50, which are respectively arranged on both sides of the water outlet.

[0034] This structure can ensure the stable rotation of the rotating sleeve 20 and can ensure that the water entering the water outlet is introduced into each injection structure 30. It has a simple structure and strong practicality.

[0035] It should be noted that the two bearings 50 , the inner wall of the rotating sleeve 20 and the outer wall of the connecting pipe 10 together form a water flow cavity connected to the water flow outlet.

[0036] In some embodiments, the bearing 50 may be Figure 1 See the structure shown. Figure 1 The bearing 50 is a sealed bearing 50, and the setting of the sealed bearing 50 can prevent leakage of the cleaning liquid.

Figure 3 , the two power output ends are arranged at intervals; the reduction gear set 45 may include three gears, one of which is connected to the drive motor, and the other is connected to the shaft of the driving gear 43, and the shaft connected to the gear arranged between the two is the power output end coaxially arranged with the connecting pipe 10.

[0045] In addition, a rotation is provided at the blocked end of the tube cavity 11 of the connecting tube 10 to allow the power output end to pass through and be rotatably connected, and a corresponding seal is provided.
