Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0042] The present application provides an acid-base neutralization tower for a can washer, which will be described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. And in the following embodiments, each embodiment has its own emphasis. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0043] To solve the technical problems in the prior art that the existing acid-base neutralization tower has a large floor area and the spray assembly 6 on the tower body 2 is not convenient for maintenance, an embodiment of the present application provides an acid-base neutralization tower for a can washer. The following will be elaborated in detail.

[0044] As Figures 1 to 4 shown, an acid-base neutralization tower for a can washer includes

[0045] a tower body 2, which is erected on the ground by a tower frame 1. An air inlet chamber and an air outlet chamber are opened in the tower body 2, and the bottoms of the air inlet chamber and the air outlet chamber are connected;

[0046] a chemical agent tank 3, which is located on the ground on one side of the tower frame 1. The chemical agent tank 3 is connected with a liquid inlet pipe 32 and a liquid outlet pipe 33, and the liquid outlet pipe 33 is connected to the bottom of the tower body 2;

[0047] an air inlet pipe group 4, one end of the air inlet pipe group 4 is connected to the acid mist collection hood of the can washer, and the other end of the air inlet pipe group 4 is connected to the air inlet chamber of the tower body 2;

[0048] an air outlet pipe group 5, the lower end of the air outlet pipe group 5 is connected to the air outlet chamber;

[0049] three spray assemblies 6, each spray assembly 6 forms a detachable and sealed connection with the tower body 2, the spray heads 63 of each spray assembly 6 are distributed in the air inlet chamber and / or the air outlet chamber, and the inlet of each spray assembly 6 is detachably connected to the liquid inlet pipe 32.

[0050] As Figure 1 shown, the tower frame 1 is formed by welding steel. The bottom is four support rods 11, the middle of the tower frame 1 is a support platform 12, and the whole tower frame 1 is an arched structure. The tower body 2 is erected on the support platform 12 through a bracket. Since the tower frame 1 is supported by four support rods 11, its floor area is very small.

[0051] The acid mist collection hood of the can washer is located below the tower frame 1. Thus, the space in the workshop can be fully utilized, and the tower body 2 does not occupy the ground position, and the workshop utilization rate is higher.

[0052] Specifically, as an optional implementation manner in this embodiment, as Figure 2 Figure 3 Figure 4 shown, the spray assembly 6 includes

[0053] An installation plate 61 is provided with two perforations, and the tower body 2 is provided with installation holes. The installation plate 61 is hermetically connected to the installation holes on the tower body 2.

[0054] Two spray pipes 62 pass through the perforations of the installation plate 61 and are welded and sealed to the installation plate 61.

[0055] The inlet of the spray pipe 62 is connected to the first flange 64, and the outlet of the liquid inlet pipe 32 is connected to the second flange 65. The first flange 64 and the second flange 65 are connected so that the liquid inlet pipe 32 is communicated with the spray pipe 62.

[0056] A plurality of spray heads 63 are all arranged on the spray pipe 62.

[0057] As Figure 2 Figure 3 shown, the installation plate 61 is connected to the tower body 2 by screws. After the installation plate 61 is installed on the tower body 2, the positions of the spray pipe 62 and the spray heads 63 in the tower cavity are fixed.

[0058] Specifically, as an alternative implementation in this embodiment, as Figure 4 shown, the spray pipe 62 includes a vertical pipe 622 and a horizontal pipe 621. Each spray head 63 is arranged on the horizontal pipe 621. The lower end of the vertical pipe 622 is connected to the first flange 64, and the first flange 64 and the second flange 65 are distributed vertically.

[0059] In this embodiment, there is one vertical pipe 622 and two horizontal pipes 621. The two horizontal pipes 621 form a U-shaped structure and are then connected to the upper end of the vertical pipe 622.

[0060] The two flanges are in an up-and-down structure. The advantage of this structure is that it is convenient to disassemble the spray assembly 6 from the tower body 2. Specifically: when the screws on the installation plate 61 are loosened and the installation plate 61 is pulled backward and translated, there will be no interference between the two flanges. The first flange 64 can be directly translated away from the second flange 65, so that the spray assembly 6 can be directly removed. When the spray assembly 6 needs to be installed, a new spray assembly 6 is directly installed, and the spray assembly 6 can be completed after the installation plate 61 and the flanges are respectively connected.

[0061] Specifically, as an alternative implementation in this embodiment, as Figure 4 shown, the tower body 2 includes

[0062] A front plate (not shown in the figure), a rear plate 21, a partition plate 23, and an annular enclosure plate 22. The front plate and the rear plate 21 are respectively arranged on the front and rear sides of the enclosure plate 22 and form a tower cavity with the enclosure plate 22. The partition plate 23 is located inside the tower cavity. The upper end of the partition plate 23 is connected to the enclosure plate 22, and both sides of the partition plate 23 are respectively connected to the front plate and the rear plate 21. An air flow channel is formed between the lower end of the partition plate 23 and the enclosure plate 22.

[0063] The air inlet pipe group 4 and the air outlet pipe group 5 are respectively connected to the enclosure plate 22; the spraying assembly 6 is connected to the rear plate 21.

[0064] The tower body 2 is made into a flat structure, which will not occupy a large space and is convenient for installation on the tower rack 1.

[0065] Specifically, as an alternative implementation manner in this embodiment, as Figure 1 Figure 2 shown, the air inlet pipe group 4 includes

[0066] an air inlet main pipe 41 and an air inlet sub-pipe 42. The air inlet sub-pipe 42 is connected to the air inlet main pipe 41. The air inlet main pipe 41 is connected to the air inlet cavity of the tower body 2. The lower ends of both the air inlet main pipe 41 and the air inlet sub-pipe 42 are connected to the acid mist collection hood of the tank washing machine.

[0067] The air inlet sub-pipe 42 is arranged horizontally, and the air inlet main pipe 41 is arranged vertically. Connecting to the acid mist collection hood through the air inlet main pipe 41 and the air inlet sub-pipe 42 can prevent acid mist from leaking from the periphery of the acid mist collection hood.

[0068] Since the air inlet sub-pipe 42 is arranged horizontally, a plurality of support rods 11 are arranged between the lower part of the air inlet sub-pipe 42 and the acid mist collection hood. The support rods 11 are used to support the air inlet sub-pipe 42 to keep it horizontally stable.

[0069] Specifically, as an alternative implementation manner in this embodiment, as Figure 2 shown, a stirrer 31 is arranged on the box body of the medicine box 3. The stirrer 31 is an existing product and can be directly purchased from the market. Adding the stirrer 31 to the medicine box 3 can not only put in liquid neutralizing liquid but also solid neutralizing materials.

[0070] For the acid-base neutralization tower for the tank washing machine of the present utility model, it is erected above the tank washing machine through the tower rack 1. The air inlet pipe group 4 is connected to the acid mist collection hood. The acid mist generated during the operation of the tank washing machine is sucked into the tower body 2. The medicine (alkali solution) is prepared in the medicine box 3. After the acid mist is introduced into the tower cavity, it passes through the air inlet cavity and the air outlet cavity in sequence and is then discharged through the air outlet pipe group 5; when the acid mist passes through the air inlet cavity and the air outlet cavity, the spraying assembly 6 sprays the acid mist to neutralize the acid mist.

[0071] For the entire acid-base neutralization tower, since it is erected above the tank washer by relying on the tower frame 1, the space above the tank washer is fully utilized, without occupying floor space, which is convenient for on-site installation and saves the floor area occupied by on-site equipment. The spraying assembly 6 is made into a module and can be detachably connected to the tower body 2 alone, which is convenient for overhaul and maintenance of the spraying assembly 6.
