[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1:

[0025] Reference Figure 1-3 A collection device for overflowing exhaust gas from a tanker truck includes a tank body 1, an inlet 2 on the top outer wall of the tank body 1, a conical cylinder 4 installed on the top outer wall of the tank body 1 at the inlet 2, a sealing component on the top inner wall of the tank body 1 at the inlet 2, and an inlet component on the top outer wall of the tank body 1 at the inlet 2.

[0026] The addition components include an arm 7, a sealing block 8 installed on the outer wall of the arm 7, an exhaust pipe 9 connected to one end of the top outer wall of the sealing block 8, and a valve 10 installed on the outer wall of one end of the exhaust pipe 9. When the arm 7 is being added, the gas in the tank 1 is exhausted through the exhaust pipe 9 connected to the arm 7, which facilitates the discharge of gas from the inner wall of the tank 1, facilitates centralized gas treatment, and avoids gas pollution of the environment.

[0027] The tank body 1 is threadedly connected to the filling port 2 with a sealing cap 3, and a sealing rubber ring is fitted on the bottom outer wall of the sealing cap 3;

[0028] The exhaust pipe 9 is connected to the loading arm 7, and the bottom outer wall of the sealing block 8 is in contact with the inner outer wall of the conical cylinder 4. The rubber ring 6 on the inner wall of the conical cylinder 4 contacts the sealing block 8 to seal the connection. The loading arm adds materials to the tank 1 through the loading arm 7. During the adding process, the air and flue gas inside the tank 1 enter the exhaust pipe 9 through the opened valve 10. The gas from the exhaust pipe 9 is convenient for subsequent processing.

[0029] The inner outer wall of the conical cylinder 4 is provided with equally spaced sealing grooves 5, and a rubber ring 6 is installed on the inner side of the conical cylinder 4 at the sealing groove 5. The loading arm 7 adds materials through the loading arm. The sealing block 8 on the loading arm 7 fits into the conical cylinder 4. After the rubber ring 6 on the conical cylinder 4 fits, it seals the connection point to prevent gas from escaping from the tank 1 and improves the tightness and sealing of the connection.

[0030] Example 2:

[0031] Reference Figure 1-2 and Figure 4The sealing assembly includes spring grooves 11 evenly spaced on the inner wall of the top of the tank 1, a tension spring 12 installed on the inner wall of the top of the spring grooves 11, and a sealing plate 14 installed on the outer wall of the bottom of the tension spring 12. When the tank 1 moves, the sealing cover 3 is screwed into the filling port 2 and the plug 16 on the sealing plate 14 is inserted into the filling port 2, thus doubly sealing the filling port 2 of the tank 1 and improving the sealing performance.

[0032] A sliding seat 13 is installed on the inner wall of the top of the tank 1 at the spring groove 11, and a support spring 15 is installed on the inner wall of the bottom of the sliding seat 13. The sealing plate 14 is slidably connected in the sliding seat 13. The tension spring 12 and the support spring 15 always support and pull the sealing plate 14 and the plug 16 upward, so that the plug 16 is always located at the filling port 2, which facilitates sealing. The sliding seat 13 ensures the stability of the sliding of the sealing plate 14.

[0033] The four outer walls of the sealing plate 14 are slidably connected to the inner wall of the sliding seat 13, and the top outer wall of the support spring 15 is connected to the outer wall of the sealing plate 14. The tension spring 12 and the support spring 15 cooperate to move the sealing plate 14 upward. The plug 16 on the sealing plate 14 is inserted into the filling port 2 to seal the tank 1 and prevent the gas inside the tank 1 from escaping.

[0034] A plug 16 is welded to the center of the top outer wall of the sealing plate 14, and the outer wall of the plug 16 is slidably connected to the inner wall of the adding port 2. The bottom outer wall and the side outer wall of the sealing block 8 are in contact with the outer wall of the rubber ring 6.

[0035] Working principle: In use, connect the loading arm 7 to one end of the loading boom. When loading tar products, remove the sealing cap 3 of the top filling port 2 of the tank body 1. Move the loading arm 7 to the filling port 2. The loading boom lowers one end of the loading arm 7. After the end of the loading arm 7 contacts the plug 16, it applies downward pressure to the plug 16. The sealing plate 14 on the plug 16 stretches the tension spring 12 and compresses the support spring 15. After the plug 16 leaves the filling port 2, the sealing block 8 on the outer wall of the loading arm 7 fits into the conical cylinder 4. The rubber ring 6 on the inner wall of the conical cylinder 4 fits into the sealing block 8. The connection is sealed. The loading arm adds material to the tank 1 through the loading arm 7. During the adding process, the air and flue gas inside the tank 1 enter the exhaust pipe 9 through the opened valve 10. The gas exits from the exhaust pipe 9 for subsequent processing. After loading is completed, the loading arm moves the loading arm 7 away from the adding port 2. The tension spring 12 and the support spring 15 work together to move the sealing plate 14 upward. The plug 16 on the sealing plate 14 is inserted into the adding port 2 to seal the tank 1 and prevent the gas inside the tank 1 from escaping. Then the sealing cover 3 is installed on the adding port 2.
