Description

Technical Field

[0001] This utility model relates to the field of asphalt discharge valves, and in particular to an anti-solidification discharge valve for asphalt transport vehicles. Background Technology

[0002] An asphalt discharge valve is a valve specifically designed for asphalt transportation systems, primarily used to control the discharge, flow, and interruption of asphalt. Asphalt typically exists as a liquid at high temperatures; therefore, the discharge valve must be designed to withstand high temperatures, corrosion, and handle high-viscosity fluids.

[0003] Existing technologies, such as the utility model patent with publication number CN207539348U, disclose an asphalt discharge valve that employs a bend and a rotary flow-limiting mechanism. The bend includes a horizontal section and a curved section. One end of the horizontal section is connected to the outlet of the asphalt tank, and the other end is connected to the curved section. The outlet end of the curved section is hinged to a rotary flow-limiting mechanism. This discharge valve not only allows for controllable flow but also prevents blockage of the flow channel within the valve body.

[0004] The inventors discovered in daily use that asphalt in existing technologies has high viscosity and solidifies upon cooling at low temperatures, causing the asphalt inside the valve to become viscous or solidified. This can clog the discharge valve's passage, hindering normal discharge or flow and preventing the equipment from operating smoothly. After cooling, the asphalt's fluidity decreases, requiring more energy or pressure to propel it out, increasing the pump's load. The solidified asphalt, resembling a solid, can cause friction against internal valve components, accelerating valve wear or damage and shortening equipment lifespan. Furthermore, because the asphalt becomes very viscous after cooling, cleaning the deposits inside the valve requires considerable time and manpower, increasing maintenance costs and equipment downtime.

[0005] This application provides another technical solution to this technical problem, aiming to provide those skilled in the art with multiple options for solving the problem. Utility Model Content

[0006] The purpose of this invention is to solve the problem that valves in the prior art are easily blocked by asphalt cooling.

[0007] To solve the above-mentioned technical problems, this utility model provides an anti-solidification discharge valve for asphalt transport vehicles, comprising: a transport tank and an auxiliary structure. A valve is provided at one end of the transport tank, and the valve is connected to the transport tank via the auxiliary structure. The arc surface of the valve is provided with an anti-clogging structure, which includes two connecting rings, both of which are fixedly connected to the valve. A sliding rod is rotatably connected to the inner wall of each connecting ring, and a circular plate is slidably connected to the arc surface of the sliding rod. Several insert rods are fixedly connected to the side of the circular plate near the connecting ring. The inner wall has several insertion holes, and the insertion rod is adapted to the insertion holes. The end of the slide rod away from the connecting ring is fixedly connected to a connecting rod. The arc surface of the connecting rod is slidably connected to a sliding plate. The ends of the two sliding plates that are close to each other are fixedly connected to a connecting ring. The inner wall of the connecting ring is fixedly connected to a heating ring. A heating core is installed inside the heating ring. Two fixing rods are fixedly connected to the lower surface of the connecting rod. A heating pump is installed inside the two fixing rods. A drag cable is installed on one side of the heating pump. The drag cable is connected to the heating core.

[0008] The aforementioned components achieve the following effects: When anti-cooling of the valve is required, the circular plate is pulled and moved. The circular plate moves on the arc surface of the slide rod, causing the insert rod to move. Then, the insert rod separates from the insertion hole. Next, the connecting rod is pulled and moved. Then, the connecting rod causes the slide rod to rotate on the inner wall of the connecting ring. After moving to the appropriate position, the insert rod is aligned with the insertion hole and then inserted into the insert rod for fixation. Then, the heating ring is aligned with the valve, and the heating pump is started. The heating pump drives the heating core to heat the heating ring. Then, the connecting ring is pushed and moved. The connecting ring causes the sliding plate to slide on the arc surface of the connecting rod. Finally, the heating ring is pushed into the valve for heating to prevent the asphalt from cooling and solidifying.

[0009] Preferably, the arc surface of the slide bar is fixedly connected to a plurality of positioning rods, and the positioning rods are slidably connected to circular plates.

[0010] The effect achieved by the above components is that the positioning rod can limit the circular plate and prevent the circular plate from shifting when it is used again.

[0011] Preferably, a handle is fixedly connected to the upper surface of the connecting ring, and the handle has a circular cross-section.

[0012] The effect achieved by the above components is that when it is necessary to pull the connecting ring, the handle can be pulled directly, and the handle will drive the connecting ring to move, making it more convenient to pull the connecting ring.

[0013] Preferably, the cross-section of the fixing rod is U-shaped, and the fixing rod is a stainless steel rod.

[0014] The effect achieved by the above components is that the stainless steel material can increase the service life of the fixing rod and prevent the fixing rod from rusting during use.

[0015] Preferably, the arc surface of the carrier tank near the valve end is provided with an auxiliary structure, the auxiliary structure including a limiting block, the limiting block being fixedly connected to the carrier tank, a connecting block being rotatably connected to the inner wall of the limiting block, a protective plate being fixedly connected to the end of the connecting block away from the limiting block, an insert plate being fixedly connected to the end of the protective plate away from the connecting block, a fixing block being fixedly connected to the side of the carrier tank away from the limiting block, the fixing block being slidably connected to the insert plate, an installation rod being slidably connected to the side of the fixing block away from the carrier tank, the installation rod being slidably connected to the insert plate, and the valve being mounted on the protective plate.

[0016] The effect achieved by the above components is as follows: when it is necessary to clean the inside of the tank, the mounting rod is pulled to move it, and then the mounting rod is separated from the insert plate and the fixing block. Then the protective plate is pulled to move it, and the protective plate drives the connecting block to move. The connecting block rotates on the inner wall of the limiting block. After moving to the appropriate position, the protective plate is separated from the transport tank, and then the inside of the transport tank is cleaned.

[0017] Preferably, a sealing gasket, which is a rubber gasket, is fixedly connected to the side of the protective plate near the transport tank.

[0018] The effect achieved by the above components is that the sealing gasket can increase the sealing between the protective plate and the transport tank, and prevent leakage from the transport tank when transporting asphalt.

[0019] Preferably, a handle is fixedly connected to the side of the protective plate away from the transport tank, and the handle has a "U" shaped cross-section.

[0020] The effect achieved by the above components is that when it is necessary to pull the protective plate, the handle can be pulled directly, and the handle will move the protective plate, making it more convenient to pull the handle.

[0021] Compared with related technologies, the anti-solidification discharge valve for asphalt transport vehicles provided by this utility model has the following beneficial effects:

[0022] By incorporating an anti-clogging structure, existing technologies address the issue that asphalt has high viscosity and solidifies at low temperatures, causing it to become viscous or hardened within the valve. This can clog the discharge valve's passage, hindering normal discharge or flow and preventing smooth equipment operation. The reduced fluidity of cooled asphalt requires more energy or pressure to propel it out, increasing pump load. Solidified asphalt, acting like a solid, can cause friction against internal valve components, accelerating wear or damage and shortening equipment lifespan. Furthermore, the high viscosity of cooled asphalt necessitates significant time and manpower for cleaning valve deposits, increasing maintenance costs and downtime. This device addresses this by providing convenient and rapid heating of the valve, preventing asphalt from cooling within the valve and heating the valve's inner wall to avoid asphalt buildup and subsequent blockage.

[0023] By setting up auxiliary structures, the transport tank can be easily opened, and the inner wall of the transport tank can be quickly cleaned, preventing the accumulation of asphalt inside the transport tank. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] Please see Figures 1 to 5 The present invention provides an anti-solidification discharge valve for an asphalt transport vehicle, comprising: a transport tank 1 and an auxiliary structure 4.

[0034] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The anti-blocking structure 3 includes two connecting rings 301, both of which are fixedly connected to the valve 2. A sliding rod 311 is rotatably connected to the inner wall of each connecting ring 301. A circular plate 312 is slidably connected to the arc surface of the sliding rod 311. Several insert rods 314 are fixedly connected to the side of the circular plate 312 closest to the connecting ring 301. Several insertion holes 313 are provided on the inner wall of the connecting ring 301, and the insert rods 314 are adapted to the insertion holes 313. A connecting rod 302 is fixedly connected to the end of the sliding rod 311 away from the connecting ring 301. The arc surface of the connecting rod 302 is slidably connected to a sliding plate 303. A connecting ring 306 is fixedly connected to one end of the two sliding plates 303 that are close to each other. A heating ring 304 is fixedly connected to the inner wall of the connecting ring 306. A heating core 307 is installed inside the heating ring 304. Two fixing rods 310 are fixedly connected to the lower surface of the connecting rod 302. A heating pump 309 is installed inside the two fixing rods 310. A drag cable 308 is installed on one side of the heating pump 309. The drag cable 308 is connected to the heating core 307. When cooling is required for valve 2, pull the circular plate 312 to move it. The circular plate 312 moves on the arc surface of the slide rod 311, causing the insert rod 314 to move. Then, the insert rod 314 separates from the insertion hole 313. Then, pull the connecting rod 302 to move it. The connecting rod 302 then causes the slide rod 311 to rotate on the inner wall of the connecting ring 301. After moving to the appropriate position, align the insert rod 314 with the insertion hole 313 and then insert the insert rod 314 for fixation. Then, heat... The ring 304 is aligned with valve 2, and then the heating pump 309 is started. The heating pump 309 drives the heating core 307 to heat the heating ring 304, which in turn pushes the connecting ring 306 to move. The connecting ring 301 drives the sliding plate 303 to slide on the arc surface of the connecting rod 302, and then pushes the heating ring 304 into valve 2 for heating to prevent the asphalt from cooling and solidifying. Several positioning rods 315 are fixedly connected to the arc surface of the sliding rod 311. The positioning rods 315 are slidably connected to the circular plate 312. The positioning rods 315 can limit the circular plate 312 to prevent it from shifting during use. A handle 305 is fixedly connected to the upper surface of the connecting ring 306. The handle 305 has a circular cross-section. When it is necessary to pull the connecting ring 306, the handle 305 can be pulled directly. The handle 305 moves the connecting ring 306, making it easier to pull the connecting ring 306. The fixing rod 310 has a U-shaped cross-section and is made of stainless steel. The stainless steel material increases the service life of the fixing rod 310 and prevents it from rusting during use.

[0035] In the embodiments of this utility model, please refer to Figures 4 to 6The auxiliary structure 4 includes a limiting block 43, which is fixedly connected to the transport tank 1. A connecting block 44 is rotatably connected to the inner wall of the limiting block 43. A protective plate 41 is fixedly connected to the end of the connecting block 44 away from the limiting block 43. A plug plate 46 is fixedly connected to the end of the protective plate 41 away from the connecting block 44.

An installation rod 48 is slidably connected to the side of the fixing block 47 away from the transport tank 1. The installation rod 48 is slidably connected to the plug plate 46. The valve 2 is installed on the protective plate 41. When cleaning the inside of the tank is required, the mounting rod 48 is pulled to move it, then the mounting rod 48 is separated from the insert plate 46 and the fixing block 47. The protective plate 41 is then pulled to move, causing the connecting block 44 to move. The connecting block 44 rotates within the inner wall of the limiting block 43. After moving to the appropriate position, the protective plate 41 separates from the transport tank 1, and the inside of the transport tank 1 is then cleaned. A sealing gasket 42, which is a rubber gasket, is fixedly connected to the side of the protective plate 41 closest to the transport tank 1. The sealing gasket 42 increases the sealing between the protective plate 41 and the transport tank 1, preventing leakage when the transport tank 1 is transporting asphalt. A handle 45, with a U-shaped cross-section, is fixedly connected to the side of the protective plate 41 furthest from the transport tank 1. When it is necessary to pull the protective plate 41, the handle 45 can be pulled directly, causing the protective plate 41 to move, making it more convenient to pull.

[0036] The working principle of the anti-freezing discharge valve for asphalt transport vehicles provided by this utility model is as follows: When anti-cooling of valve 2 is required, the circular plate 312 is pulled to move. The circular plate 312 moves on the arc surface of the slide rod 311, and the circular plate 312 drives the insertion rod 314 to move. Then, the insertion rod 314 separates from the insertion hole 313. Then, the connecting rod 302 is pulled to move. Then, the connecting rod 302 drives the slide rod 311 to rotate on the inner wall of the connecting ring 301. After moving to the appropriate position, the insertion rod 314 is aligned with the insertion hole 313 and then the insertion rod 314 is inserted and fixed. Then, the heating coil 304 is aligned with valve 2, and then the heating pump 309 is started to operate. The heating pump 309 drives the heating coil to move. Heating core 307 heats the heating coil 304, which in turn pushes the connecting ring 306 to move. Connecting ring 301 drives sliding plate 303 to slide on the arc surface of connecting rod 302. Then, heating coil 304 is pushed into valve 2 for heating to prevent asphalt from cooling and solidifying. Positioning rod 315 can limit the circular plate 312 to prevent it from shifting during use. When it is necessary to pull the connecting ring 306, the handle 305 can be pulled directly. The handle 305 drives the connecting ring 306 to move, making it easier to pull the connecting ring 306. The stainless steel material can increase the service life of fixing rod 310 and prevent it from rusting during use.

[0037] When it is necessary to clean the inside of the tank, pull the mounting rod 48 to move it, then separate the mounting rod 48 from the insert plate 46 and the fixing block 47, and then pull the protective plate 41 to move it. The protective plate 41 drives the connecting block 44 to move, and the connecting block 44 rotates on the inner wall of the limiting block 43. After moving to the appropriate position, the protective plate 41 separates from the transport tank 1, and then the inside of the transport tank 1 is cleaned. The sealing gasket 42 can increase the sealing between the protective plate 41 and the transport tank 1 to prevent leakage when the transport tank 1 is transporting asphalt. When it is necessary to pull the protective plate 41, the handle 45 can be pulled directly. The handle 45 drives the protective plate 41 to move, making it more convenient to pull the handle 45.
