[0025] Please refer to Figure 1 , and now a kind of accident acid collection device provided by the present invention will be described. A kind of accident acid collection device includes a mobile trolley, a collection tank 5, and a scrubbing tank 6 filled with a filtering and purifying liquid 11. The collection tank 5 and the scrubbing tank 6 are sequentially arranged on the mobile trolley from front to back. On the front side of the top of the collection tank 5, an acid suction pipe 7 is provided. At the end of the acid suction pipe 7, an acid suction broom 10 is provided. On the rear side of the top of the collection tank 5, a connecting pipe 8 is provided. A vacuum pump 9 is provided on the connecting pipe 8, and the vacuum pump 9 is arranged on the mobile trolley. The end of the connecting pipe 8 extends into the filtering and purifying liquid 11 in the scrubbing tank 6. A tail gas discharge pipe 12 is provided on the top of the scrubbing tank 6.

[0026] For a kind of accident acid collection device provided by the present invention, compared with the prior art, the acid suction broom 10 is placed in the area where there is accident acid on the ground. The vacuum pump 9 is started, and the vacuum pump 9 forms a negative pressure in the collection tank 5 through the connecting pipe 8. The accident acid is sucked into the collection tank 5 through the acid suction broom 10 and the acid suction pipe 7 for collection. The gas inhaled into the connecting pipe 8 will have a certain amount of acidic gas due to contact with the accident acid. The end of the connecting pipe 8 is extended into the filtering and purifying liquid 11 in the scrubbing tank 6. After the air with acidic gas passes through the filtering and purifying liquid 11, the acidic gas in the air is removed, and finally the air discharged through the tail gas discharge pipe 12 does not contain acidic gas. For a kind of accident acid collection device provided by the present invention, the collection tank 5, the scrubbing tank 6, and the vacuum pump 9 are all arranged on the mobile trolley. The mobile trolley can drive the above-mentioned equipment to move as a whole. The acid suction broom 10 can complete the collection of accident acid in different areas along with the mobile trolley, without manual removal of the accident acid. Through the negative pressure method, the accident acid can be removed more cleanly and thoroughly.

[0027] Please refer to Figures 2 to 3, the acid suction broom 10 includes a connecting pipe 13, an acid suction housing, and a grille plate 16. The connecting pipe 13 is connected to the end of the acid suction pipe 7. The upper port of the acid suction housing is sealingly connected to the acid suction pipe 7. The grille plate 16 is installed at the lower port of the acid suction housing, and a plurality of strip-shaped through holes 17 are sequentially formed in the grille plate 16. The acid suction pipe 7 is a flexible pipe, and the acid suction broom 10 can be twisted at multiple angles. The connecting pipe 13 is a rigid pipe, and an operator can hold the connecting pipe 13 for operation. The interior of the acid suction housing has an acid liquid channel. The accident acid enters the acid liquid channel through the plurality of strip-shaped through holes 17 on the grille plate 16 under the action of negative pressure, and then enters the collection tank 5 through the connecting pipe 13 and the acid suction pipe 7.

[0028] Please refer to Figure 3 , the lower port of the acid suction housing is an oblong hole, and the grille plate 16 is an oblong plate adapted to the shape of the lower port of the acid suction housing. The plurality of strip-shaped through holes 17 are arranged at equal intervals along the length direction of the oblong plate, and a single strip-shaped through hole 17 extends along the width direction of the oblong plate. The strip-shaped through holes 17 can enable the accident acid to enter the acid suction housing, and at the same time can effectively block external sundries, preventing the external sundries from being sucked into the collection tank 5 together with the accident acid.

[0029] Specifically, please refer to Figure 2 , the acid suction housing includes a connecting sleeve 14 in the upper part and a flared housing 15 in the lower part. The connecting sleeve 14 is threadedly connected to the lower end of the connecting pipe 13. The grille plate 16 is embedded in the lower port of the acid suction housing. A positioning ring 18 is clamped on the end face of the lower port of the acid suction housing, and the positioning ring 18 is used to press-fit and position the grille plate 16. Among them, the upper end of the connecting sleeve 14 has an external thread, and the lower end of the connecting pipe 13 has an internal thread. The two are threadedly connected and sealed with a sealing ring. The upper end face of the positioning ring 18 is circumferentially provided with a clamping block, and the lower end face of the acid suction housing is circumferentially provided with a corresponding clamping groove. The end of the clamping block has an anti-detachment part with a width greater than itself. After the grille plate 16 is installed, the clamping block is inserted into the clamping groove by an external force, the anti-detachment part is clamped in the clamping groove, and the positioning ring 18 is press-fitted on the outer circumference of the grille plate 16, which can keep the grille plate 16 stable.

[0030] Please refer to 2 and Figure 4 , an elastic sleeve 19 with an axial resilience is sleeved on the outer circumference of the lower port of the acid suction housing, and the lower end of the elastic sleeve 19 protrudes from the lower port of the acid suction housing. When using the acid suction broom 10 to adsorb the accident acid, press the acid suction broom 10 towards the area of the accident acid, and the accident acid located inside the elastic sleeve 19 can be sucked into the collection tank 5 by negative pressure.

[0031] Preferably, an avoidance notch 20 is formed on one side of the elastic sleeve 19. The avoidance notch 20 can ensure the internal space of the elastic sleeve 19 is in communication with the outside world, preventing the elastic sleeve 19 from being adsorbed to the area of the accidental acid due to negative pressure and being difficult to separate. In addition, the acid suction broom 10 is also dragged in the direction of the avoidance notch 20, forming an operation mode similar to cleaning debris with a "broom". The surrounding accidental acid will continuously enter the inside of the elastic sleeve 19 through the avoidance notch 20, thereby realizing the continuous collection of the accidental acid.

[0032] Please refer to Figure 1 , a partition 21 is provided on the top surface of the inner cavity of the collection tank 5. The partition 21 is located at the front side of the inner cavity of the collection tank 5, and the acid suction pipe 7 is located in front of the partition 21. The accidental acid entering the collection tank 5 through the acid suction pipe 7 will be blocked by the partition 21, and the accidental acid entering the collection tank 5 will flow down along the front side surface of the partition 21. The process of the accidental acid entering the collection tank 5 is more stable, which can not only reduce noise but also avoid the accidental acid from splashing into the connecting pipe 8.

[0033] Preferably, a liquid level gauge 22 is provided on the front inner wall of the collection tank 5. The liquid level gauge 22 is located below the partition 21. A drain pipe 23 is provided at the lower part of the outer wall of the collection tank 5, and a control valve 24 is provided on the drain pipe 23. The liquid level gauge 22 is electrically connected to the control valve 24 through a controller. When the liquid level of the accidental acid collected in the collection tank 5 reaches the position of the liquid level gauge 22, the liquid level gauge 22 sends a signal to the controller, and the controller sends a control signal to the control valve 24. The control valve 24 opens to discharge the accidental acid in the collection tank 5. When the accidental acid is discharged, the control valve 24 closes, and the collection of the accidental acid continues. The presence of the liquid level gauge 22 can prevent the accidental acid in the collection tank 5 from accumulating too much and blocking the lower end of the partition 21, affecting the acid suction operation.

[0034] A liquid supplement pipe 25 is provided at the top of the scrubbing tank 6, which can timely supplement the filtration and purification liquid 11 in the scrubbing tank 6. A drain pipe 26 is provided at the bottom of the scrubbing tank 6, which can cooperate with the liquid supplement pipe 25 to replace the filtration and purification liquid 11. A dust-proof cap 27 is provided at the end of the tail gas discharge pipe 12, and the dust-proof cap 27 can prevent sundries from falling into the filtration and purification liquid 11 through the tail gas discharge pipe 12.

[0035] Preferably, the filtration and purification liquid 11 can be pure water or weakly alkaline water.

[0036] Specifically, a gas distribution sleeve 28 is sleeved at the end of the connecting pipe 8. A plurality of ventilation holes are formed on the outer periphery of the gas distribution sleeve 28. The gas discharged from the end of the connecting pipe 8 is discharged into the filtration and purification liquid 11 through the plurality of ventilation holes on the gas distribution sleeve 28, which can make the gas and the filtration and purification liquid 11 have a larger contact area and improve the absorption effect of the acidic gas.

[0037] In addition, the mobile trolley includes a vehicle body 1, a handrail 2 at the rear side of the vehicle body 1, and wheels 3 at the bottom of the vehicle body 1. The operator pushes and pulls the handrail 2 by means of the wheels 3 to move the mobile trolley. The collection tank 5, the scrubbing tank 6, and the vacuum pump 9 are all installed on the upper end surface of the vehicle body 1, so that the movement of the entire collection device can be realized. In addition, a storage battery 4 is further arranged at the rear side of the upper end surface of the vehicle body 1. The storage battery 4 can provide power for the movement of the mobile trolley and at the same time can also provide electrical energy for relevant components on the collection device, such as the vacuum pump 9, the liquid level gauge 22, and the control valve 24, etc.

[0038] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
