DETAILED DESCRIPTION

[0024] Embodiment 1

[0025] like Figure 1-Figure 4 As shown, the utility model provides a fermentation tank alkali solution spraying device, comprising a delivery pipe 1, a rotating disk 2, a connector 5, a sealing device 8 and a spraying assembly;

[0026] The rotating disk 2 is rotatably arranged on the conveying pipe 1, and a connecting device 3 for rotatably connecting the rotating disk 2 is arranged on the conveying pipe 1; a rotating mechanism 4 for driving the rotating disk 2 to rotate is arranged on the conveying pipe 1; a plurality of connecting heads 5 are arranged, and the plurality of connecting heads 5 are all arranged on the rotating disk 2; a plurality of sealing devices 8 are arranged corresponding to the connecting heads 5, and are respectively arranged in the plurality of connecting heads 5; a plurality of spray components are arranged, and the spray components are arranged on the connecting heads 5 and abut against the sealing device 8.

[0027] The rotating mechanism 4 includes an impeller 402 disposed in the delivery pipe 1 , a rotating shaft 403 disposed on the rotating disk 2 and rotatably disposed on the impeller 402 , and a mounting frame 401 disposed on the rotating shaft 403 and located in the delivery pipe 1 .

[0028] In this embodiment, the delivery pipe 1 is extended into the fermentation tank to be cleaned, and alkali solution is introduced into the delivery pipe 1. When the alkali solution flows through the rotating mechanism 4, it drives the mounting frame 401 to rotate, and the mounting frame 401 drives the rotating shaft 403 to rotate, and the rotating shaft 403 drives the rotating disk 2 to rotate, so that the rotating disk 2 drives the connecting head 5 to rotate, and the connecting head 5 drives the spray assembly to move; when the spray assembly is installed on the connecting head 5, the sealing device 8 is in a conducting rotation so that the alkali solution can flow. If the spray assembly is not installed on the connecting head 5, the connecting head 5 is blocked by the sealing device 8 to prevent the alkali solution from overflowing; the alkali solution flows into the connecting pipe 6 and then into the spray pipe 7. Due to the flow rate of the alkali solution combined with the centrifugal force during rotation, the spray pipe 7 is straightened and close to the inner wall of the fermentation tank, so that the alkali solution can impact the inner wall of the fermentation tank, and the inner wall of the fermentation tank is preliminarily cleaned, thereby reducing the amount of alkali solution used.

[0029] Embodiment 2

[0030] like Figure 1-Figure 4As shown, the utility model proposes an alkali liquid spraying device for a fermentation tank. Compared with the first embodiment, the connecting device 3 in this embodiment includes a support plate 302 arranged on the conveying pipe 1, a limiting plate 301 arranged on the rotating plate 2 and slidably connected to the support plate 302, a plurality of connecting frames 303 are arranged and all are arranged on the conveying pipe 1, and a plurality of pulleys 304 are respectively rotatably arranged on the plurality of connecting frames 303 and abut against the limiting plate 301.

[0031] In this embodiment, when assembling the rotating disk 2, the rotating disk 2 is sleeved on the lower end of the conveying pipe 1, so that the limit plate 301 is against the lower part of the support plate 302, and the support plate 302 limits the maximum upward movement of the rotating disk 2. After the installation is completed, the connecting frame 303 is inserted into the limit plate 301, so that the pulley 304 is in contact with the limit plate 301, and then the connecting frame 303 is screwed into the conveying pipe 1 by bolts for fixing. The connecting frame 303 supports and fixes the pulley 304, so that the pulley 304 can support the limit plate 301, and the limit plate 301 supports the rotating disk 2, completing the installation of the rotating disk 2, and the pulley 304 can reduce the friction of the limit plate 301, thereby facilitating the rotation of the rotating disk 2.

[0032] Embodiment 3

[0033] like Figure 1-Figure 4 As shown, the present invention proposes a fermentation tank alkali solution spraying device. Compared with the first or second embodiment, the spraying assembly in this embodiment includes a connecting pipe 6 connected to a connector 5 at one end, a spraying pipe 7 arranged on the other end of the connecting pipe 6, and a push rod frame 9 arranged in the connecting pipe 6 and abutting against a sealing device 8. The sealing device 8 includes a support frame 804 arranged in the connector 5, a sliding rod 802 slidably arranged on the support frame 804, a sealing block 801 arranged on the sliding rod 802 and slidably connected and sealed to the connector 5, and an elastic member 803 arranged on the sliding rod 802 and connected to the support frame 804 and the sealing block 801 at both ends. A push rod is arranged on the side of the sealing block 801 away from the support frame 804; the push rod frame 9 abuts against the push rod.

[0034] When the water is not in contact with the spray assembly, the elastic member 803 pushes the sealing block 801 against the connecting head 5, so that the connecting head 5 is in a sealed state and no liquid will overflow; when the connecting pipe 6 is sleeved on the connecting head 5, the connecting pipe 6 drives the push rod frame 9 to move, so that the push rod frame 9 contacts the push rod, pushes the push rod to move, and the push rod pushes the sealing block 801 to move, so that the sealing block 801 is separated from the connecting head 5, so that the alkali solution can be sprayed out from the gap between the sealing block 801 and the connecting head 5, flows into the connecting pipe 6, and then flows into the spray pipe 7 through the connecting pipe 6, and is sprayed onto the inner wall of the fermentation tank through the spray pipe 7 to clean the fermentation tank; through this structure, multiple connecting heads 5 will work only after they are in contact with the spray assembly, and will not work if they are not in contact with the spray assembly, so that the number of connecting heads 5 that work can be selected according to the use needs. Under the condition that the water pressure remains unchanged, the fewer the number of connecting heads 5, the faster the flow rate sprayed from the spray assembly.

[0035] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
