Description

Technical Field

[0001] This utility model relates to the field of oil refining and chemical technology, and in particular to a storage tank with a level gauge probe cleaning function. Background Technology

[0002] A level gauge is an instrument that detects changes in the height of solid materials in a container in real time. Level gauges are widely used in industries such as petrochemicals, plastics, cement, pharmaceuticals, feed, food, metallurgy, light industry, building materials, and environmental protection to achieve upper and lower limit alarms and control of material levels.

[0003] The "Level Gauge for Refining and Chemical Industry" disclosed in Chinese Utility Model Patent (Announcement No.: CN216978068U) includes a horizontal drive unit, a curved rod, a first longitudinal drive unit, a second longitudinal drive unit, a U-shaped connecting assembly, and a level gauge assembly; the output end of the horizontal drive unit is vertically arranged.

[0004] To address the issue of insufficient measurement accuracy, existing technologies employ a method where the output ends of the second longitudinal drive unit and the first longitudinal drive unit are vertically positioned on the same horizontal plane, thereby driving the level gauge assembly to rotate along two mutually perpendicular axes within the horizontal plane. Alternatively, by vertically positioning the transverse drive unit, its output end can drive the level gauge assembly to rotate along a vertical axis. However, this method still results in material adhering to the level gauge probe, leading to inaccurate level gauge measurements. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. When the probe is placed in the tank for a long time, material will stick to its surface, affecting the accuracy of the probe measurement. At this time, the motor on the top plate drives the gear to rotate, which causes the ring gear meshing on its surface to rotate inside the shell, thereby driving the rotating ring to rotate. The electronic telescopic rod rotates accordingly. At the same time, the electronic telescopic rod extends and pushes the connecting ring to move downward, so that the connecting rod drives the scraping ring to rotate and move downward, scraping off the material sticking to the probe surface, thus improving the accuracy of the device.

[0012] 2. This utility model enables quick installation and fixation of the level gauge. At the same time, the sealing gasket and sealing ring work together to prevent the gas inside the tank from escaping. When the gas inside the tank presses against the fixing plate, it can also make the locking block more secure, so that the gas can only be discharged from the vent valve on the surface of the tank, avoiding the leakage of harmful gases and improving the adaptability of the device.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments:

[0023] like Figure 1-4 As shown, this utility model provides a storage tank with a level gauge probe cleaning function, including a tank body (1), a detachable level gauge (2) and a fixing mechanism (3). The top of the tank body (1) is provided with an opening, and the detachable level gauge (2) is installed at the opening.

[0024] The detachable level gauge (2) includes a cover plate (201), a housing (216) is fixedly installed on the top of the cover plate (201), a ring gear (202) is movably installed inside the housing (216), a gear (203) meshes with the inner ring surface of the ring gear (202), a top plate (205) is fixedly installed on the top of the housing (216), a display (206) is fixedly installed on the top of the top plate (205), a motor (204) is fixedly installed on the top of the top plate (205), and the output end of the motor (204) passes through the top plate (205) and is fixedly installed on the gear. At the center of (203), a fixing ring (208) is fixedly installed at the bottom of the cover plate (201). The fixing ring (208) and the cover plate (201) are an integral structure. The fixing ring (208) has a locking block (209) on its outer periphery. A sealing ring (207) is fixedly installed on the outer periphery of the bottom end of the cover plate (201). A probe (212) is fixedly installed at the center of the bottom end of the cover plate (201). The display (206) is electrically connected to the probe (212). The probe (212) is a radio frequency admittance level gauge. A scraping mechanism is fixedly installed at the bottom end of the ring gear (202).

[0025] The scraping mechanism includes a rotating ring (210), which is fixedly installed at the bottom end of the ring gear (202). The rotating ring (210) is movably installed between the inner ring of the fixed ring (208) and the probe (212). An electronic telescopic rod (211) is fixedly installed at the bottom end of the rotating ring (210). A connecting ring (213) is fixedly installed at the telescopic end of the electronic telescopic rod (211). A scraping ring (215) is provided at the center of the connecting ring (213). The scraping ring (215) is fixedly connected to the connecting ring (213) through multiple sets of connecting rods (214). The scraping ring (215) is sleeved on the outer circumference of the probe (212). The inner ring size of the scraping ring (215) is adapted to the outer circumference size of the probe (212).

[0026] The fixing mechanism (3) includes a fixing seat (301), which is fixedly arranged around the opening on the top surface of the tank (1). The surface of the fixing seat (301) is provided with a slot (302), which is adapted to the locking block (209). The inside of the fixing seat (301) is provided with a locking groove (304), which is adapted to the locking block (209). A sealing gasket (303) is fixedly installed on the top of the fixing seat (301), which is adapted to the sealing ring (207). An annular clamp (306) is movably installed inside the fixing seat (301). Multiple sets of springs (305) are evenly fixedly installed at the bottom end of the annular clamp (306) and the top of the tank (1).

[0027] The working principle of this utility model is as follows:

[0028] First, insert the probe (212) into the tank (1) from the top opening of the tank (1). Align the locking block 209 on the outer periphery of the fixing ring 208 with the slot 302 and press it down. At this time, the locking block 209 pushes the clamping plate 306 to squeeze the spring 305, so that the spring 305 is compressed. Rotate the locking block 209 so that the locking block 209 is aligned with the slot 304. The spring 305 pushes the clamping plate 306 to lock the locking block 209 into the slot 304. The sealing gasket 303 and the sealing ring 207 fit tightly together, completing the installation and fixing of the level gauge. The sealing gasket 303 and the sealing ring 207 can make it difficult for the gas inside the tank 1 to escape. When the gas inside the tank 1 presses against the fixing plate 208, it can also make the locking block 209 more secure, so that the gas can only be discharged from the vent valve on the surface of the tank 1, avoiding the leakage of harmful gases.

[0029] The probe 212 emits a radio frequency signal to detect the material inside the tank 1 and displays the remaining material in the tank 1 on the display 206. When the probe 212 is placed in the tank 1 for a long time, material will stick to its surface, affecting the accuracy of the probe 212 measurement. At this time, the motor 204 on the surface of the top plate 205 drives the gear 203 to rotate, causing the ring gear 202 meshing on its surface to rotate inside the housing 216, which in turn drives the rotating ring 210 to rotate. The electronic telescopic rod 211 rotates accordingly. At the same time, the electronic telescopic rod 211 extends and pushes the connecting ring 213 downward, causing the connecting rod 214 to drive the scraper ring 215 to rotate and move downward, scraping off the material sticking to the surface of the probe 212, thus improving the accuracy of the device.

[0030] The present invention has thus far described the technical solution of the present invention with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present invention.
