Description

Technical Field

[0001] This utility model relates to the field of transport vehicle technology, and in particular to a splash-proof device for an asphalt insulation transport vehicle. Background Technology

[0002] With the rapid development of highway construction and transportation in my country, the number of various engineering transport vehicles is also increasing significantly. Among them, tank trucks used for transporting liquid substances are widely used. Tank trucks are used to transport liquid substances such as liquid asphalt, crude oil, gasoline, diesel, and liquid chemical products. For non-toxic or non-volatile liquid substances such as liquid asphalt and crude oil, vents or ventilation pipes are installed on the top of the asphalt tank during transportation to maintain normal pressure inside the tank. When the vehicle accelerates or brakes, due to the fluidity and inertia of the liquid, the liquid fluctuates inside the asphalt tank, and the liquid level changes rapidly and significantly. Some liquid substances, such as asphalt and crude oil, will flow out of the asphalt tank onto the ground outside the tank through the ventilation pipes, wasting liquid substances and causing environmental pollution.

[0003] There is a need for a structure that can properly vent air during normal and stable transportation, and help prevent splashing when the surface of the asphalt liquid is disturbed, thereby reducing waste and protecting the environment. Therefore, it is necessary to design a splash-proof device for asphalt insulation transport vehicles. Utility Model Content

[0004] The main purpose of this utility model is to provide a splash-proof device for asphalt insulation transport vehicles, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A splash-proof device for an asphalt insulation transport vehicle includes a transport tank. A splash-proof pipe is fixedly connected to the upper surface of the transport tank. A sealing cap is installed on the upper surface of the splash-proof pipe. An exhaust pipe is installed on the upper left side of the sealing cap. A small exhaust hole is annularly formed on the lower surface of the exhaust pipe. The exhaust pipe passes through the sealing cap. A limiting tube is sleeved on the lower surface of the exhaust pipe. A large exhaust hole is annularly formed on the lower surface of the limiting tube. A large moving rod is movably connected to the middle of the limiting tube. A baffle is fixedly connected to the upper surface of the large moving rod. A small moving rod is fixedly connected to the upper surface of the baffle. The small moving rod passes through the exhaust pipe. A limiting block is fixedly connected to the inner wall of the splash-proof pipe. A support plate is rotatably connected to the outer surface of the limiting block. A suspension block is fixedly connected to one end of the support plate.

[0006] In order to prevent external garbage from entering and to collect some of the leaked asphalt liquid, as a splash-proof device for an asphalt insulation transport vehicle of this utility model, a protective cover is fixedly connected to the upper surface of the exhaust pipe, and a storage tank is opened on the upper surface of the sealing cover near the exhaust pipe.

[0007] In order to collect internal pressure when the device is sealed, a hydraulic accumulator is installed on the upper right surface of the sealing cover as a splash-proof device for an asphalt insulation transport vehicle according to this utility model.

[0008] In order to help limit the length of the moving rod, as a splash-proof device for an asphalt insulation transport vehicle of this utility model, the top of the small moving rod is threaded with a limiting nut.

[0009] In order to improve protection, the splash-proof device for an asphalt insulation transport vehicle of this utility model has sealing protective pads symmetrically arranged on the upper and lower outer surfaces of the baffle.

[0010] In order to achieve the purpose of heat preservation, as a splash-proof device for an asphalt heat preservation transport vehicle of this utility model, the inner side wall of the transport vehicle tank is provided with a heat preservation layer.

[0011] In order to achieve the purpose of preventing pollution and extending service life, the anti-splashing device of the asphalt insulation transport vehicle of this utility model also includes an anti-stick and heat-resistant coating, which is applied to the outer surface of each component.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, the components include a transport tank, a splash guard, a sealing cap, an exhaust pipe, a small exhaust hole, a limiting pipe, a large exhaust hole, a large moving rod, a baffle, a small moving rod, a limiting block, a support plate, and a suspension block. The splash guard and sealing cap are fixed to the top of the transport tank. The transport tank stores asphalt liquid. The position and length of the small moving rod are adjusted so that the bottom end of the large moving rod touches the support plate. When stationary, the suspension block floats on the upper surface. The large and small exhaust holes are connected for normal exhaust. When the liquid level rises, the suspension block rises, causing the large moving rod on the support plate to move upward. The baffle blocks the small exhaust hole, achieving a sealed environment and preventing asphalt splashing. The limiting block limits the movement range of the suspension block and the support plate, ensuring that it never avoids the large moving rod, reducing asphalt liquid waste and protecting the environment.

[0013] 2. In this utility model, by setting up a protective cover, a storage tank, and a hydraulic energy storage device, the protective cover prevents external impurities from falling into the tank of the transport vehicle. The storage tank can store the small amount of asphalt vapor carried out with the gas and cooled and liquefied asphalt liquid, preventing turbulence. When the small vent hole is blocked, although it prevents liquid from splashing out, the internal pressure increases due to the blockage of the vent hole, which is harmful. At this time, the hydraulic energy storage device can collect and store the pressure, and convert and reuse the stored energy through other control and execution components. It can be used to drive the transport vehicle or other components that require energy such as insulation, thereby improving energy utilization. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example like Figure 1-5 As shown, an anti-splash device for an asphalt insulation transport vehicle includes a transport tank 1, an anti-splash pipe 2 fixedly connected to the upper surface of the transport tank 1, a sealing cap 3 installed on the upper surface of the anti-splash pipe 2, and an exhaust pipe 4 installed on the upper left side of the sealing cap 3. In this embodiment, a small exhaust hole 5 is annularly opened on the lower surface of the exhaust pipe 4. The exhaust pipe 4 passes through the sealing cover 3. A limiting tube 6 is sleeved on the lower surface of the exhaust pipe 4. A large exhaust hole 7 is annularly opened on the lower surface of the limiting tube 6. A large moving rod 8 is movably connected to the middle of the limiting tube 6. A baffle 9 is fixedly connected to the upper surface of the large moving rod 8. A small moving rod 10 is fixedly connected to the upper surface of the baffle 9. The small moving rod 10 passes through the exhaust pipe 4. A limiting block 11 is fixedly connected to the inner side wall of the splash guard 2. A support plate 12 is rotatably connected to the outer surface of the limiting block 11. A suspension block 13 is fixedly connected to one end of the support plate 12.

[0018] In practical use, the splash guard 2 and the sealing cap 3 are fixed to the top of the transport tank 1. The transport tank 1 stores asphalt liquid. The position and length of the small moving rod 10 are adjusted so that the bottom end of the large moving rod 8 touches the support plate 12. When stationary, the suspension block 13 is suspended on the upper surface. The large vent hole 7 on the limiting pipe 6 and the small vent hole 5 on the vent pipe 4 are connected to allow normal venting. When the liquid level rises, the suspension block 13 rises, causing the large moving rod 8 on the support plate 12 to move upward. The baffle 9 blocks the small vent hole 5, achieving a sealed environment and preventing asphalt splashing. The limiting block 11 limits the movement range of the suspension block 13 and the support plate 12 so that they never avoid the large moving rod 8, reducing asphalt liquid waste and protecting the environment.

[0019] In this embodiment, a protective cover 14 is fixedly connected to the upper surface of the exhaust pipe 4, and a storage groove 15 is opened on the upper surface of the sealing cover 3 near the exhaust pipe 4.

[0020] In practical use, there is a gap at the connection between the protective cover 14 and the exhaust pipe 4 to facilitate exhaust. The protective cover 14 prevents external impurities from falling into the inside of the transport vehicle tank 1. The storage tank 15 can store the small amount of asphalt liquid cooled and liquefied by the asphalt vapor carried out with the gas, thus preventing turbulence.

[0021] In this embodiment, a hydraulic accumulator 16 is installed on the upper right surface of the sealing cover 3.

[0022] In practical use, when the small vent 5 is blocked, although it prevents liquid from splashing out, the internal pressure increases due to the blockage of the vent, which is harmful. At this time, the hydraulic accumulator 16 can collect and store the pressure, and then convert and reuse the stored energy through other control actuators. It can be used to drive transport vehicles or other components that require energy, such as insulation, thereby improving energy utilization.

[0023] In this embodiment, the top end of the small moving rod 10 is threadedly connected to a limiting nut 17.

[0024] In practical use, the limiting nut 17 can limit the length of the small moving rod 10.

[0025] In this embodiment, sealing gaskets 18 are symmetrically arranged on the upper and lower outer surfaces of the baffle 9.

[0026] In practical use, the sealing gasket 18 can protect the contact surfaces of the baffle 9 with the exhaust pipe 4 and the limiting pipe 6 during the up and down movement, and prevent damage from impacts.

[0027] In this embodiment, the inner wall of the transport tank 1 is provided with a heat insulation layer 19.

[0028] In practical use, the insulation layer 19 can protect the temperature of the transport tank 1 and prevent the asphalt liquid from losing temperature.

[0029] In this embodiment, an anti-stick and heat-resistant coating 20 is also included, which is applied to the outer surface of each component.

[0030] In practical applications, the non-stick, high-temperature resistant coating 20, whose main component is an inorganic-organic composite ceramic coating, can protect the components from contamination in high-temperature asphalt liquid environments and extend their service life.

[0031] Working principle: During use, the splash guard 2 and the sealing cap 3 are fixed to the top of the transport tank 1. The transport tank 1 stores asphalt liquid. The position and length of the small moving rod 10 are adjusted so that the bottom end of the large moving rod 8 touches the support plate 12. When stationary, the suspension block 13 is suspended on the upper surface. The large vent hole 7 on the limiting pipe 6 and the small vent hole 5 on the vent pipe 4 are connected for normal venting. When the liquid level rises, the suspension block 13 rises, driving the large moving rod 8 on the support plate 12 to move upward. The baffle 9 blocks the small vent hole 5, achieving a sealed environment and preventing asphalt splashing. The limiting block 11 limits the movement range of the suspension block 13 and the support plate 12, ensuring that it never avoids the large moving rod 8. The actuator 8 reduces asphalt waste and protects the environment. The protective cover 14 has a gap at the connection with the exhaust pipe 4 to facilitate exhaust. The protective cover 14 prevents external impurities from falling into the tank 1 of the transport vehicle. The storage tank 15 can store the small amount of asphalt vapor carried out with the gas and cooled and liquefied asphalt liquid to prevent turbulence. When the small exhaust hole 5 is blocked, although it prevents liquid from splashing out, the internal pressure increases due to the blockage of the exhaust hole, which is harmful. At this time, the hydraulic accumulator 16 can collect and store the pressure. After being converted and reused by other control actuators, it can be used to drive the transport vehicle or other components that require energy, such as insulation, to improve energy utilization.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
