Description

Technical Field

[0001] This utility model belongs to the technical field of ammonium nitrate oil frying vehicle, specifically relating to an exhaust device for the oil storage tank of an ammonium nitrate oil frying vehicle. Background Technology

[0002] The on-site ammonium nitrate (AM) explosive loading truck (hereinafter referred to as AM explosive truck) is a special vehicle used in open-pit mines, engineering blasting, and other scenarios. It can complete the mixing and borehole loading of AM explosives at the blasting site and belongs to the category of special operation equipment related to civilian explosives. The AM explosive truck mainly consists of an ammonium nitrate silo, an oil storage tank, and a driver's cab installed on the vehicle. The oil storage tank is equipped with a refueling port and an exhaust port. During refueling, the oil injected into the tank is sprayed down, which easily mixes with air, resulting in a large number of air bubbles in the diesel fuel in the storage tank. These bubbles then burst, producing a large amount of oil vapor, which is directly discharged from the exhaust port, carrying away a large amount of diesel fuel. The diesel fuel falls onto the surface of the storage tank, easily contaminating the vehicle body and wasting diesel fuel. An existing patent (publication number CN214456808U) discloses a diesel loading device for a mixed ammonium nitrate explosive vehicle. The patent has an exhaust pipe at the exhaust port of the oil tank, and several baffles are set on the inner wall of the exhaust pipe to collect oil vapor. A large amount of diesel gas liquefies and flows back into the oil tank along the baffles, avoiding the waste of diesel. However, the exhaust pipe and its internal baffles are fixed in the exhaust pipe, which makes subsequent maintenance and structural upgrades inconvenient and the maintenance cost high.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0017] Example: Figure 1 and Figure 2As shown, this embodiment provides an exhaust device for the oil tank of an ammonium nitrate explosive (ANFO) vehicle, including a vehicle body 1, an oil tank 2, and a filter cover 3. The oil tank 2 is mounted on the vehicle body 1, and an exhaust pipe 21 is provided at the upper end of the oil tank 2; the filter cover 3 is used to cover the opening of the exhaust pipe 21, and several filter holes 31 are opened on the filter cover 3; an inner tube 4 is detachably fixedly installed at the lower part of the filter cover 3, and the inner tube 4 is used to be inserted into the exhaust pipe 21. Several baffles 41 are arranged along the axis in the inner tube 4, and filter cotton 5 is provided at the top of the inner tube 4.

[0018] This design makes it easy to remove the inner pipe 4 for cleaning or replacement, keeps the exhaust pipe 21 clean, ensures smooth exhaust, extends its service life, facilitates upgrades to the exhaust pipe 21, and reduces the maintenance or structural upgrade costs of the exhaust system.

[0019] Preferably, the filter cover 3 is detachably and fixedly connected to the exhaust pipe 21 via a flange structure, improving the installation stability of the filter cover 3. The exhaust pipe 21 can have a square cross-section. The inner pipe 4 and the filter cover 3 can be fixedly connected by a threaded connection structure, or they can be connected by an integral molding method.

[0020] In the exhaust device of the oil storage tank of an ammonium nitrate explosive vehicle according to this embodiment, a filter plate 6 is detachably fixed to the inner wall of the exhaust pipe 21, and the filter plate 6 is located below the inner pipe 4. With this configuration, the filter plate 6 works in conjunction with the filter cover 3 and the baffle plate 41. While ensuring the normal operation of exhaust and filtration, the filter cover 3 or the filter plate 6 can be removed separately for inspection or replacement. After removing one of the filter components (filter cover 3 or filter plate 6), the other filter component continues to work, thus avoiding affecting the normal filtration function of the exhaust pipe 21.

[0021] In the exhaust device of the oil storage tank of the ammonium nitrate explosive vehicle of this embodiment, an insertion interface 211 is provided on the side wall of the exhaust pipe 21. The insertion interface 211 is used for taking out and putting in the filter plate 6. This setting is simple in structure, convenient for taking out and putting in the filter plate 6, and has low maintenance cost.

[0022] In the exhaust device of the oil tank of an ammonium nitrate explosive vehicle according to this embodiment, a handle 61 is fixedly installed on the edge of the filter plate 6, and a baffle 62 that matches and fits the outer wall of the exhaust pipe 21 is provided on the handle 61. With this configuration, when the filter plate 6 is installed in the exhaust pipe 21, the baffle 62 is used to cover the connector 211 to prevent dust from entering and to prevent gas in the oil tank from being discharged through the connector 211.

[0023] In the exhaust device of the oil storage tank of an ammonium nitrate explosive vehicle according to this embodiment, an annular support platform 212 is provided on the inner peripheral wall of the exhaust pipe 21 to support the filter plate 6. This arrangement improves the installation stability of the filter plate 6.

[0024] In the exhaust device of the oil storage tank of an ammonium nitrate explosive vehicle according to this embodiment, a positioning hole 213 is provided on the annular support platform 212, and a positioning block 63 is fixedly provided on the lower part of the filter plate 6. The positioning block 63 is inserted and positioned in the positioning hole 213 to position the filter plate 6 in the exhaust pipe 21. This arrangement further improves the installation stability of the filter plate 6 and provides a good positioning effect.

[0025] In the exhaust device of the oil storage tank of an ammonium nitrate explosive vehicle according to this embodiment, a positioning seat 7 is fixedly installed on the outer wall of the exhaust pipe 21. A positioning groove 71 is opened on the upper part of the positioning seat 7, and a positioning rod 64 is fixedly installed on the lower part of the handle 61. The positioning rod 64 is inserted and positioned in the positioning groove 71 to position the filter plate 6 in the exhaust pipe 21. The positioning rod 64 and the positioning seat 7, as well as the positioning hole 213 and the positioning block 63, achieve internal and external positioning, which improves the stability of the filter plate 6 and avoids the risk of unstable installation of the filter plate 6 due to the positioning hole 213 and the positioning block 63 not being properly positioned.

[0026] In the exhaust device of the oil storage tank of an ammonium nitrate explosive vehicle according to this embodiment, an annular sealing ring 42 is provided on the outer wall of the inner mounting pipe 4, and the outer wall of the annular sealing ring 42 matches and fits the inner peripheral wall of the exhaust pipe 21. This arrangement improves the installation sealing of the filter cover 3 and prevents gas from being directly discharged from the gap between the inner mounting pipe 4 and the exhaust pipe 21.

[0027] In the exhaust device of the oil tank of an ammonium nitrate explosive vehicle in this embodiment, a cover plate 214 is provided on the outer wall of the exhaust pipe 21. The upper end of the cover plate 214 is rotatably connected to the outer wall of the exhaust pipe 21, and the cover plate 214 is used to cover the insertion interface 211. With this arrangement, when the filter plate 6 is removed for maintenance or replacement, the cover plate 214 rotates downward under the action of gravity to cover the insertion interface 211, preventing the gas in the oil tank 2 from being directly discharged from the insertion interface 211.
