Description

Technical Field

[0001] The present invention relates to the field of bulk materials such as thermal power plants and cement industries, and more specifically, to a material level monitoring device with a dust overflow prevention function for a bulk tank truck. Background Art

[0002] Tank trucks are tank-shaped transport vehicles used to transport various liquids, liquefied gases, and powdered goods, including gasoline, crude oil, various viscous oils, vegetable oils, liquid ammonia, alcohol, water, various acidic and alkaline liquids, cement, and lead oxide powder. Tank trucks play a crucial role in transportation, accounting for approximately 18% of all trucks. They are commonly used to transport raw materials in thermal power plants and the cement industry.

[0003] When filling fly ash from power plants into bulk tank trucks, the system often uses the rear filling port. The front filling port is used to monitor the filling level. Due to the positive pressure inside the tank truck during filling (especially when just transporting the ash into the tank), a large amount of dust will be sprayed outward from the front filling port, seriously polluting the environment. In addition, manual observation of the dust level inside the tank body is usually used, which is not only dangerous but also has an impact on the health of the observer. Therefore, we propose a level monitoring device with dust overflow prevention function for bulk tank trucks to solve the above problems. Summary of the Invention

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0030] Reference Figure 1-Figure 5 A material level monitoring device with dust-overflow prevention function for a bulk tank truck comprises a vehicle body, a driver's cabin and a tank body 1.

[0031] The vehicle body includes a tank body 1 and a feed hopper 2. The function of the feed hopper 2 is to facilitate the filling of fly ash from the power plant into the tank body 1; and

[0032] A monitoring device 3 is installed on the tank body 1 to measure the liquid level inside the tank body 1; and

[0033] The sound and light alarm 4 is installed on the tank body 1 of the vehicle. The controller is electrically connected to the sound and light alarm 4. The sound and light alarm 4 is used to warn and remind relevant staff to close the filling valve to prevent the fly ash inside the tank body 1 from overflowing.

[0034] A feed hopper 2 is installed on the tank body 1 of the vehicle tank, a controller is installed in the cockpit, a front filling port and a rear filling port are provided on the tank body 1 of the vehicle tank, the feed hopper 2 is installed on the rear filling port, and the monitoring device 3 is installed on the front filling port.

[0035] The rear filling port is used for filling fly ash, and the front filling port is used to facilitate exhaust and maintain the air pressure balance inside the tank body 1 of the vehicle tank.

[0036] The controller is not only used to control the opening and closing of the rotary level meter 306, but also can receive the signal of the rotary level meter 306 and control the sound and light alarm 4 to issue an alarm reminder. It should be noted that the rotary level meter 306, the controller and the sound and light alarm 4 are all powered by the powder tank truck, and the controller is installed in the cockpit of the powder tank truck. The purpose is to facilitate the driver to control the operating status of the rotary level meter 306. When the tank body 1 of the vehicle does not need to be filled with fly ash, the rotary level meter 306 can be controlled to stop running.

[0037] The monitoring device 3 includes a support tube 304 installed on the tank body 1 and with an opening at the lower end. The support tube 304 is provided with multiple exhaust holes. A rotary level meter 306 is installed on the top of the support tube 304. The rotary level meter 306 is electrically connected to the controller. A linkage shaft 3061 is installed at the output end of the rotary level meter 306. The bottom of the linkage shaft 3061 passes through the support tube 304 and extends into the tank body 1. A rotating plate 3062 is installed at the bottom of the linkage shaft 3061. The outer wall of the support tube 304 is provided with a filter layer 305.

[0038] The monitoring device 3 also includes a sealing ring 301 installed on the top of the tank body 1. The bottom side wall of the support cylinder 304 is connected to the sealing ring 301 through a fixing ring 303. The sealing ring 301 is provided with an annular mounting groove corresponding to the fixing ring 303.

[0039] The rotary level meter 306 can monitor the material level inside the tank body 1 of the vehicle tank in real time. When the material level reaches a certain level, the resistance of the rotary level meter 306 to the rotation of the rotating piece 3062 becomes larger and reaches the threshold value. The switch blade of the rotary level meter 306 is closed due to the resistance, and the signal is sent to the controller. The controller controls the sound and light alarm 4 to issue an alarm reminder.

[0040] The function of the filter layer 305 is to filter the air discharged from the tank body 1 of the vehicle tank, prevent the dust in the dust-laden gas, and discharge the clean air into the atmosphere, thus completely solving the problem of filling environmental pollution.

[0041] The support cylinder 304 is composed of a stainless steel cylinder and a stainless steel sealing plate, and a plurality of exhaust holes are provided on the surface of the support cylinder 304 for the purpose of supporting and fixing the rotary level meter 306. At the same time, the exhaust holes on the support cylinder 304 do not affect the discharge of air inside the tank body 1, so that the air pressure inside the tank body 1 remains balanced.

[0042] In the present invention, more specifically, the sealing ring 301 is connected to the tank body 1 by attraction through multiple strong magnetic blocks 302. The multiple strong magnetic blocks 302 are arranged around the center of the sealing ring 301, and an installation cavity corresponding to the strong magnetic block 302 is provided on the sealing ring 301.

[0043] The function of the sealing ring 301 is to seal, and cooperate with the strong magnetic block 302 to stably adsorb on the top of the vehicle tank body 1, and at the same time, the support tube 304 can also be fixed on the top of the vehicle tank body 1.

[0044] In the present invention, more specifically, the filter layer 305 is needle-punched felt filter cotton.

[0045] In the present invention, more specifically, the bottom of the filter layer 305 is fixedly connected to the top of the sealing ring 301 .

[0046] The present invention can be explained through the following operation mode:

[0047] In the present invention, the fly ash of the power plant is filled through the rear filling port of the tank car body 1. During the filling process, the air inside the tank car body 1 is discharged through the front filling port. During the discharge process, the dust carried in the air is filtered through the filter layer 305, and the clean air is discharged into the atmosphere, which completely solves the problem of filling environmental pollution. When the material level in the tank car body 1 reaches a certain height, the switch blade of the rotary level meter 306 is closed due to resistance. The controller receives the signal that the switch blade of the rotary level meter 306 is closed due to resistance. The controller controls the sound and light alarm 4 to issue an alarm reminder, and the relevant staff closes the filling valve. The rotary level meter 306 is used to monitor the material level in the tank car body 1 in real time. Not only does it not require manual real-time observation of the material level in the tank car body 1, but it can also reduce the impact on the health of the relevant staff.
