Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cleaning industrial measuring equipment, and in particular relates to the installation structure of a radar level gauge cleaner for an open slurry storage tank. Background Technology
[0002] The slurry storage tank is an open-top design. In industrial applications, during feeding, slurry may splash into the radar level gauge's emission area, obstructing the gauge's measurement and leading to inaccurate readings. This can further cause issues such as slurry spillage, disrupting normal production. Traditional cleaning methods rely on manual disassembly or high-pressure water guns, which have the following drawbacks: 1. Low efficiency: Manual cleaning requires stopping the machine for disassembly; 2. Incomplete cleaning: The fixed nozzle cannot cover the entire surface of the level gauge; 3. Poor safety: High-pressure water washing may damage precision components, and there are significant safety hazards when cleaning manually at some installation locations. Utility Model Content
[0003] (1) Technical problem to be solved: In view of the problems of labor-intensive and time-consuming cleaning methods, safety risks and insufficient cleaning effect, this utility model provides a radar level gauge cleaner installation structure for open slurry storage tanks, so as to achieve cleaning of radar level gauges without disassembly.
[0004] (2) The technical solution adopted by this utility model is as follows: An installation structure for a radar level gauge cleaner for an open slurry storage tank is disclosed. The radar level gauge is fixed above the open end of the slurry storage tank by a bracket. A cleaner is installed on the top of the slurry storage tank. The cleaner includes a housing, a cylinder, and a support. A drive shaft is rotatably connected to the top of the housing. A rotating cleaning brush is fixed to the top of the drive shaft. A cleaning spray bar is fixed to the top of the housing, with a nozzle and a water inlet on the spray bar. A motor is installed inside the housing, and the output shaft of the motor is fixedly connected to the drive shaft. The support is fixed to the top of the slurry storage tank. The cylinder body is fixed to the support, and the piston rod of the cylinder is fixed to the housing. When the piston rod of the cylinder extends, the rotating cleaning brush is positioned below and in contact with the radar level gauge.
[0005] A further technical solution is that a sliding rod is fixed on the outer shell, a sliding sleeve is fixedly installed on the support, and the sliding rod passes through the sliding sleeve and is slidably connected to it.
[0006] A further technical solution involves setting two arc-shaped plates at the bottom of the support, which are clamped on the tank wall of the slurry storage tank, with a set screw threaded onto the outer arc-shaped plate.
[0007] A further technical solution is that the rotating cleaning brush includes a disc base, the disc base is fixed to the drive shaft, and bristles are fixedly arranged on the top of the disc base.
[0008] (3) Due to the adoption of the above technical solution, the beneficial effect of this utility model is: by setting a cleaner on the top of the slurry storage tank, the motor housing drives the rotating cleaning brush to rotate, and the cleaning spray rod and nozzle can spray water onto the brush. When the piston rod of the cylinder extends, the rotating cleaning brush is located below and in contact with the radar level gauge. At this time, the emission area of the radar level gauge can be cleaned. There is no need for manual disassembly and cleaning during the process, and the water will not directly impact the radar level gauge. After cleaning, the piston rod of the cylinder can be retracted.

Detailed Implementation
[0010] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0011] like Figures 1-5 As shown.
[0012] Example 1: An installation structure for a radar level gauge cleaner for an open slurry storage tank. The radar level gauge 1 is fixed above the open end of the slurry storage tank 3 by a bracket 2. A cleaner 4 is installed on the top of the slurry storage tank 3. The cleaner 4 includes a housing 5, a cylinder 6, and a support 7. A drive shaft 8 is rotatably connected to the top of the housing 5. A rotating cleaning brush 9 is fixed to the top of the drive shaft 8. A cleaning spray bar 10 is fixed to the top of the housing 5. A nozzle 11 and a water inlet 12 are provided on the cleaning spray bar 10. A motor 13 is installed inside the housing 5. The output shaft of the motor 13 is fixedly connected to the drive shaft 8 (the drive shaft 8 and the disc base 18 are rotatably connected by a bearing, which has a sealing function. The housing of the motor 13 is fixed to the inner wall of the housing 5). The support 7 is fixed to the top of the slurry storage tank 3. The cylinder body of the cylinder 6 is fixed to the support 7. The piston rod of the cylinder 6 is fixed to the housing 5. When the piston rod of the cylinder 6 extends, the rotating cleaning brush 9 is located below and in contact with the radar level gauge 1. Two arc-shaped plates 16 are provided at the bottom of the support 7. The two arc-shaped plates 16 are clamped on the tank wall of the slurry storage tank 3. The outer arc-shaped plates 16 are threaded with set screws 17 (tightening the set screws 17 can fix the support 7 to the tank wall of the slurry storage tank 3). The rotating cleaning brush 9 includes a disc base 18, which is fixed to the drive shaft 8. Brush bristles 19 are fixedly provided on the top of the disc base 18.
[0013] Working process: Motor 13 is a pneumatic motor. Its air inlet is connected to an air pipeline. The air pipeline passes through the side of the outer casing 5 and connects to an electric valve (solenoid valve), a filter pressure reducing valve, and an air source (air compressor or air tank). Cylinder 6 is connected to the control valve and the air source through the air pipeline. The water inlet 12 of the cleaning spray bar 10 is connected to the water supply pipeline and the air supply pipeline through a T-junction. The water supply pipeline connects to the water control valve, pump, and water source, and the air supply pipeline connects to the air control valve and air source. In the initial state, the piston rod of cylinder 6 is in the retracted state. When it is necessary to clean the radar level gauge 1, the piston rod of the control cylinder 6 is extended. At this time, the rotating cleaning brush 9 is located below and in contact with the radar level gauge 1. Air is supplied to motor 13 to drive the rotating cleaning brush 9 to rotate. At the same time, water is supplied to the cleaning spray bar 10 to spray water onto the brush and clean the transmitting part of the radar level gauge 1. After a period of time, the water spraying stops, and air is supplied to the cleaning spray bar 10 to dry the brush and the radar level gauge 1 using airflow. Since the brush is made of a soft material (the material of the brush is not specified), it will not damage the radar level gauge 1. After cleaning, the piston rod of the control cylinder 6 can be retracted. Because the slurry storage tank 3 is always open without a cover, the setting of the cleaner 4 will not affect the function of the slurry storage tank 3 itself. Moreover, the slurry storage tank 3 already contains water and slurry, so what is cleaned is only slurry and water, and will not affect the function of the slurry storage tank 3 itself. When the piston rod of the cylinder 6 extends and the rotating cleaning brush 9 contacts the transmitting area of the radar level gauge 1, the brush will bend because it is soft, until the entire brush covers the transmitting area of the radar level gauge 1.
[0014] Example 2: Based on Example 1, a sliding rod 14 is fixed on the outer casing 5, and a sliding sleeve 15 is fixed on the support 7. The sliding rod 14 passes through the sliding sleeve 15 and is slidably connected to it. By setting the sliding rod 14 and the sliding sleeve 15, the cylinder 6 can be made to operate more stably. The top of the outer casing 5 is flat, and the bottom is spherical. The spherical part and the flat part are connected by bolts or welding.
[0015] The above are merely preferred embodiments of this utility model.
