Description

Technical Field

[0001] This utility model relates to the field of tanker loading pipe technology, and in particular to a tanker loading pipe with an exhaust gas absorption structure. Background Technology

[0002] Currently, chemical companies typically need to transfer materials from storage tanks to tank trucks during product material storage and transportation operations. Operators insert the loading pipe connected to the storage tank directly into the inlet of the tank truck, and use a pump unit to draw the product material from the storage tank into the loading pipe, and then pour the material into the tank truck's storage tank through the loading pipe.

[0003] However, when filling tank trucks with materials that pose an environmental pollution risk, a large amount of exhaust gas will continuously escape from the inlet of the tanker truck. This exhaust gas often contains toxic and harmful components. If this exhaust gas is released directly into the external environment without treatment, it will not only pose a serious threat to the health of on-site operators, but may also lead to pollution of the surrounding environment.

The vertical outward right-angle elbow is located on the outer side of the vertical inward right-angle elbow, and an annular air intake interlayer is formed between the two. The straight pipe is fixedly connected to the end of the vertical outward right-angle elbow away from the outer pipe. The straight pipe is located on the outer side of the straight-rotation pipe, and an annular air intake interlayer is formed between the two. The end of the transverse right-angle elbow away from the straight-rotation pipe penetrates the side wall of the straight pipe and extends to its outside. An air intake assembly is connected to the end of the straight pipe away from the vertical outward right-angle elbow.

[0008] Optionally, the air intake assembly includes a connecting pipe assembly and a fan. One end of the connecting pipe assembly is fixedly connected to a straight pipe, and the interior of the connecting pipe assembly is connected to the annular air intake jacket. The other end of the connecting pipe assembly is connected to the air intake port of the fan, and the exhaust port of the fan is connected to a recycling and treatment device.

[0009] Optionally, a connecting cylinder is fixedly connected to the upper end of the suction hood, and the connecting cylinder is threaded onto the lower outer side of the outer tube.

[0010] Optionally, the telescopic feeding tube includes a main tube and a secondary tube. The main tube is fixedly connected to the lower end of the vertical inward right-angle bend, and the secondary tube is slidably sleeved on the lower outer side of the main tube.

During material transport via the filling pipeline, the air intake assembly and pump unit start synchronously. The operation of the air intake assembly creates a negative pressure in the first annular air intake jacket. This negative pressure draws the exhaust gas generated during material filling into the first annular air intake jacket, preventing it from escaping into the external environment. Subsequently, this drawn-in exhaust gas passes through the second and third annular air intake jackets, ultimately being drawn in and processed by the air intake assembly.

[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0029] Please see Figure 1-9 This utility model provides a tanker loading pipe with a waste gas suction structure, including a loading pipe connected to a storage tank 1. The loading pipe includes a telescopic discharge pipe 2, a straight-turn pipe 4, and a transfer pipe assembly 6. The telescopic discharge pipe 2 is installed vertically, and a vertical inner right-angle elbow 3 is fixedly connected to the upper end of the telescopic discharge pipe 2. The straight-turn pipe 4 is installed horizontally, and one end of the straight-turn pipe 4 is fixedly connected to the end of the vertical inner right-angle elbow 3 away from the telescopic discharge pipe 2. The other end of the straight-turn pipe 4 is fixedly connected to a horizontal right-angle elbow 5. One end of the transfer pipe assembly 6 is fixedly connected to the end of the horizontal right-angle elbow 5 away from the straight-turn pipe 4. The other end of the transfer pipe assembly 6 is connected to the storage tank 1 through a pump unit.

[0030] An air suction pipe is provided on the outside of the telescopic feeding pipe 2. The air suction pipe includes an outer pipe 7 and a straight pipe 9. The outer pipe 7 is located on the outside of the telescopic feeding pipe 2, and an annular air suction interlayer 100 is formed between the two. The lower end of the outer pipe 7 is detachably connected to an air suction hood 71. The upper end of the outer pipe 7 is fixedly connected to a vertical outer right-angle bend 8. The vertical outer right-angle bend 8 is located on the outside of the vertical inner right-angle bend 3, and an annular air suction interlayer 200 is formed between the two. The straight pipe 9 is fixedly connected to the end of the vertical outer right-angle bend 8 away from the outer pipe 7. The straight pipe 9 is located on the... An annular suction jacket 300 is formed on the outside of the adapter pipe 4 and between the two. The annular suction jacket 100, the annular suction jacket 200 and the annular suction jacket 300 are connected. The straight pipe 9 is stably supported above the ground by a support wall or support frame. The end of the transverse right-angle bend 5 away from the straight adapter pipe 4 passes through the side wall of the straight pipe 9 and extends to its outside. The penetration point needs to be sealed to prevent gas leakage in the annular suction jacket 300. The end of the straight pipe 9 away from the vertical outer right-angle bend 8 is connected to the suction assembly.

[0031] Specifically, when it is necessary to transfer materials from storage tank 1 to the tanker truck's storage tank, once the tanker truck has moved to the loading area and the tanker truck's storage tank inlet is directly below the telescopic discharge pipe 2, the operator controls the extension of the telescopic discharge pipe 2 so that the lower end of the telescopic discharge pipe 2 is fully inserted into the tanker truck's storage tank. Then, the pump unit is started, which draws the materials from storage tank 1 into the loading pipeline. In the loading pipeline, the materials pass through the transfer pipe assembly 6, the horizontal right-angle bend 5, the straight transfer pipe 4, and the vertical inner right-angle bend 3, finally flowing from the telescopic discharge pipe 2 into the tanker truck's storage tank.

[0032] Simultaneously with the start-up of the pump unit, the suction assembly also operates. The operation of the suction assembly creates a negative pressure within the annular suction jacket 100. This negative pressure draws the waste gas generated during the material injection process into the annular suction jacket 100, preventing it from escaping into the external environment. Subsequently, this drawn-in waste gas passes through the annular suction jacket 200 and the annular suction jacket 300, ultimately being drawn in and processed by the suction assembly.

[0033] It should be noted that the outer tube 7 is located outside the telescopic feed tube 2. To ensure that their relative positions are fixed, a bracket can be used for fixation, thereby preventing the telescopic feed tube 2 and the outer tube 7 from shifting (not shown in the attached diagram). Similarly, the vertical outer right-angle bend 8 and the vertical inner right-angle bend 3, as well as the straight tube 9 and the straight-turn connector 4, can all be fixed using brackets.

[0034] Furthermore, the air intake assembly includes a connecting pipe assembly 10 and a fan 11. One end of the connecting pipe assembly 10 is fixedly connected to the straight pipe 9, and the interior of the connecting pipe assembly 10 is connected to the annular air intake interlayer 300. The other end of the connecting pipe assembly 10 is connected to the air intake port of the fan 11, and the exhaust port of the fan 11 is connected to a recycling and processing device 12.

[0035] Specifically, when the suction assembly draws in exhaust gas, the fan 11 generates suction through its operation. This suction allows the exhaust gas in the annular suction jacket 300 to be drawn into the fan 11 via the connecting pipe assembly 10, and then discharged into the recycling and treatment device 12 through the exhaust port of the fan 11. The recycling and treatment device 12 then treats the exhaust gas before it is discharged.

[0036] Furthermore, a connecting cylinder 711 is fixedly connected to the upper end of the suction hood 71, and the connecting cylinder 711 is threaded onto the lower outer side of the outer tube 7.

[0037] Specifically, the suction hood 71 can effectively concentrate and guide the exhaust gas, allowing it to directly enter the annular suction jacket 100, thus improving the collection efficiency of the exhaust gas. In addition, the suction hood 71 adopts a threaded detachable structure, which facilitates subsequent disassembly and maintenance.

[0038] Furthermore, the telescopic feeding tube 2 includes a main tube 21 and a secondary tube 22. The main tube 21 is fixedly connected to the lower end of the vertical inner right-angle bend 3. The secondary tube 22 is slidably sleeved on the lower outer side of the main tube 21. A driving component is provided on the outer side of the main tube 21 to drive the secondary tube 22 to slide up and down relative to the main tube 21.

[0039] Specifically, during material filling, after the tanker truck moves to the loading area, the operator drives the auxiliary pipe 22 to slide downward relative to the main pipe 21 via the drive mechanism, thereby increasing the length of the telescopic discharge pipe 2. At this time, the lower end of the telescopic discharge pipe 2 gradually inserts into the inlet of the tanker truck's storage tank, ensuring that the material can be smoothly transported into the tanker truck's storage tank. After filling is completed, the auxiliary pipe 22 is driven upward relative to the main pipe 21 via the drive mechanism, thereby shortening the length of the telescopic discharge pipe 2. At this time, the lower end of the telescopic discharge pipe 2 gradually disengages from the inlet of the tanker truck's storage tank, and the tanker truck can drive away smoothly.

[0040] Furthermore, multiple sets of equally spaced and evenly distributed sealing rings 23 are embedded in the upper end of the inner wall of the secondary pipe 22. The sealing rings 23 are positioned between the main pipe 21 and the secondary pipe 22 to achieve a seal.

[0041] Specifically, when the drive component drives the secondary pipe 22 to slide relative to the main pipe 21, the sealing ring 23 between the secondary pipe 22 and the main pipe 21 plays a sealing role, ensuring that the two remain tightly connected during the sliding process, thereby effectively preventing material leakage.

[0042] Furthermore, the upper outer side of the main tube 21 is symmetrically fixed with a main ear plate 211, and the lower outer side of the secondary tube 22 is symmetrically fixed with a secondary ear plate 221. The driving component includes two sets of electric push rods 25. The upper ends of the two sets of electric push rods 25 are respectively fixedly connected to the lower surface of the two sets of main ear plates 211, and the telescopic ends of the two sets of electric push rods 25 are respectively fixedly connected to the two sets of secondary ear plates 221.

[0043] Specifically, the telescopic ends of the two sets of electric push rods 25 extend synchronously, thereby pushing the two sets of auxiliary ear plates 221 and auxiliary tubes 22 to descend relative to the main tube 21. The telescopic ends of the two sets of electric push rods 25 retract synchronously, thereby driving the two sets of auxiliary ear plates 221 and auxiliary tubes 22 to rise relative to the main tube 21.

[0044] Furthermore, the outer side of the electric push rod 25 is provided with a guide 24, which includes an outer sleeve 241 and an inner sleeve 242. The upper end of the outer sleeve 241 is fixedly connected to the lower surface of the main ear plate 211, and the inner sleeve 242 is slidably sleeved on the inner side of the outer sleeve 241. The lower end of the inner sleeve 242 is fixedly connected to the auxiliary ear plate 221.

[0045] Specifically, the electric push rod 25 is provided with an outer sleeve 241 and an inner sleeve 242, which can protect the electric push rod 25. At the same time, the guide member 24 limits the sliding path of the secondary tube 22. When the electric push rod 25 drives the secondary tube 22 to move up and down relative to the main tube 21, the inner sleeve 242 will also move up and down relative to the outer sleeve 241. The outer sleeve 241 plays a limiting and guiding role for the inner sleeve 242, so that it can only slide in the vertical direction.

[0046] It should be noted that: 1. In this embodiment, the pump unit equipment, the fan 11 in the air intake assembly, and the recycling and treatment device 12 can be interlocked for control, thereby achieving synchronous operation. The circuit structure and control method involved here are all existing technologies and will not be described in detail here. 2. The recycling and treatment device 12 is an existing device capable of recycling and treating waste gas.

[0047] The above are merely preferred embodiments of this utility model and are not intended to limit this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
