Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic level gauges, in particular to an ultrasonic level gauge with anti-fog cleaning function. Background Art

[0002] In the measurement of ultrasonic level meter, ultrasonic pulse is emitted by sensor (transducer), and sound wave is received by the same sensor or ultrasonic receiver after being reflected by liquid surface, and converted into electrical signal by piezoelectric crystal or magnetostrictive device, and the distance from sensor to the surface of liquid to be measured is calculated by the time between emission and reception of sound wave. Due to the non-contact measurement, the measured medium is almost unlimited, and it can be widely used for the measurement of height of various liquids and solid materials. Ultrasonic level meter consists of three parts: ultrasonic transducer, processing unit and output unit. At the same time, ultrasonic level meter is suitable for tank, reservoir, water tank and boiler level detection open channel The liquid level is detected in places such as flow measurement. In the production of water-coal slurry, the ball mill grinds the water-coal slurry made of water-coal slurry, water and dispersant at high speed. The water-coal slurry generates a lot of heat due to friction. The high-temperature water-coal slurry flows into the buffer tank from the discharge port of the ball mill, causing a large amount of steam to emerge from the water-coal slurry in the buffer tank. If the liquid level control is too high, the coal slurry covers the ultrasonic level meter probe, making the buffer tank level detection inaccurate, which is harmful to the production equipment. At the same time, the existing steam is easily dissipated in the operating environment, which easily causes fog to adhere to the surface of the ultrasonic level meter, which in turn makes the operator unable to directly observe and handle the ultrasonic level meter.

[0010] Preferably, the steam collection and cleaning device includes a collection box, a condensation plate, a T-limit block, a two-way pipe connector, a through frame, a filter element, a pressurized water pump, a delivery pipe group, a connecting pipe group and an atomizing nozzle.

[0011] By adopting the above technical solution, a filter element is provided, through which the cooling water passing through the condensation plate is filtered, thereby preventing the cooling water from containing a large amount of solid particles. At the same time, the cooling water containing a large amount of solid particles is transported to the connector through a high-pressure water pump to clean the detection head. This in turn can easily cause the high-pressure water pump to become blocked internally after long-term use, and can also cause the solid particles in the cooling water to contact the detection head through the water, thereby easily causing the detection head to malfunction.

[0012] Preferably, the ball nut, the L-plate, the first scraper, the first micro screw and the first micro motor constitute a moving mechanism, and the moving distance range of the moving mechanism is 0-15 cm.

[0013] By adopting the above technical solution, an L-plate is provided, which achieves a two-way connection effect, and the L-plate shortens the contact distance between the first scraper and one side of the outer wall of the groove mounting frame, while facilitating the first scraper to defog the mist attached to the surface of one side of the outer wall of the groove mounting frame.

[0019] By adopting the above technical solution, a micro hydraulic telescopic rod is provided, which not only plays a connecting and driving effect, but also changes the relative height distance between the connecting plate and the inside of the groove mounting frame, thereby avoiding the connecting plate blocking the display meter and affecting the operator's direct observation of the display meter.

[0020] Preferably, the installation angle between the condensation plate and the collection box ranges from 45° to 90°.

[0024] Compared with the prior art, the invention has the following beneficial effects: the ultrasonic level meter with anti-fog cleaning function,

[0025] (1) A groove installation frame and a first micro motor are provided, and the display meter is wrapped and installed by the groove installation frame, so as to prevent the steam emitted in the working environment from directly adhering to and contacting the surface of the display meter, and at the same time causing fog to appear on the surface of the display meter, which in turn causes the operator to be unable to directly observe the ultrasonic level meter. The first micro motor drives the first screw rod to move during operation, and drives the ball nut to move in the same direction during the movement of the first screw rod, and drives the L rod to move in the same direction during the movement of the ball nut. In turn, the fog attached to one side of the outer wall of the groove installation frame is defogged by the first scraper during the movement of the L rod, so as to prevent the fog from adhering to the surface of the groove installation frame, which in turn affects the operator's direct observation of the ultrasonic level meter.

[0026] (2) A steam collection and cleaning device is provided, which contacts and processes the steam through a condensation plate, and cools the steam after contact through the condensation plate. At the same time, the cooled condensed water flows into the collection box through a filter element. When the thickness sensor senses that the thickness of the surface of the detection head is too thick, the thickness sensor transmits a signal to the controller, and the controller starts the high-pressure water pump to work. During the operation of the high-pressure water pump, the cooling water inside the collection box is transported to the inside of the connecting pipe group, and the cooling water entering the inside of the connecting pipe group is sprayed out through an atomizing nozzle. At the same time, the sprayed water cleans the coal slurry attached to the detection head, thereby avoiding excessive adhesion of coal slurry on the surface of the detection head, resulting in inaccurate level detection of the buffer tank, which is harmful to the production equipment;

[0027] (3) A defogger is provided on both sides. When the humidity sensor senses that the humidity inside the groove installation frame is high, the humidity sensor transmits a signal to the controller. The controller controls the second micro motor to work. During the operation of the second micro motor, the second screw rod is driven to move. During the movement of the second screw rod, the screw block is driven to move. During the movement of the screw block, the third connecting member group is driven to move in the same direction. The third connecting member group moves in the same direction to change the rotational inclination angle between the groove scraper and the connecting plate. When the screw block moves to the maximum movement limit, the sponge scraper contacts one side of the inner wall of the groove installation frame and the surface of the display meter respectively. At the same time, the controller controls the micro hydraulic telescopic rod to work. During the operation of the micro hydraulic telescopic rod, the connecting plate is driven to move in the same direction. During the movement of the connecting plate, the sponge scraper is driven to remove the fog attached to one side of the inner wall of the groove installation frame and the surface of the display meter respectively, thereby preventing the fog from cooling into condensed water and entering the interior of the display meter through the connecting gap between the display meters, and causing the circuit inside the display meter to short-circuit and open circuit.

[0028] (4) A small heat dissipation motor is provided, and the heat generated during the operation of the display meter and the heat inside the groove installation frame are transported and processed during the operation of the small heat dissipation motor, so as to avoid the display meter being always in a state of being wrapped by the groove installation frame, causing the display meter to be affected by the working environment temperature and the temperature inside the groove installation frame, thereby causing the display meter to malfunction. In addition, the small heat dissipation motor works in a reverse working mode, which can not only prevent fog from entering the groove installation frame, but also transport and discharge the fog entering the groove installation frame, and at the same time transport and process the heat generated by the groove installation frame and the display meter.

The condensation plate 1302 is installed above the collection box 1301, and the installation angle range between the condensation plate 1302 and the collection box 1301 is The installation angle between the condensation plate 1302 and the collection box 1301 is 45°-90°. If the installation angle between the condensation plate 1302 and the collection box 1301 is other than that, not only the contact area between the condensation plate 1302 and the steam in the environment is reduced, but also the steam after contact has a large friction with the condensation plate 1302, and the cooling water cannot flow through the condensation plate 1302 to the collection box 1301 for collection and treatment. In order to avoid the above situation, the installation angle between the condensation plate 1302 and the collection box 1301 is 45° for installation.

The filter element 1306 is installed in turn according to the number of groups of the through frame 1305, and the aperture of the filter element 1306 installed below is smaller than that of the upper one, so as to filter the solid particles with smaller diameters.

[0043] Working principle: When using the ultrasonic level gauge with anti-fog cleaning function, first manually connect the connector 1 to the corresponding tank body. When the bottom of the other through plate group 3 contacts the tank body, the connector 1 and the corresponding tank body are installed. When the steam inside the tank body contacts the detection head 2, the detection head 2 transmits the signal to the display meter 4. At this time, the display meter 4 detects and displays the liquid level inside the tank body. At the same time, the controller controls the first micro motor 11 and the small heat dissipation motor 6 to work. The first micro motor 11 drives the first micro screw 10 to move. The first micro screw 10 drives the ball nut 7 to move. The ball nut 7 drives the first scraper 9 through the L plate 8 to defog one side of the outer wall of the groove installation frame 5. During the operation of the small heat dissipation motor 6 The heat is discharged from the inside of the groove installation frame 5. When the groove installation frame 5 is attached with mist, the humidity sensor transmits the signal to the controller. The controller controls the second micro motor 1210 and the micro hydraulic telescopic rod 1211 to work. The second micro motor 1210 drives the second screw rod 1209 to move. The second screw rod 1209 drives the wire block 1206 to move. The wire block 1206 drives the third connecting member group 1207 to move in the same direction. During the movement of the third connecting member group 1207, the second connecting member 1205 is driven to move relative to one side of the groove scraper 1203 through the double-hole connecting rod 1208. During the movement of the groove scraper 1203, the sponge scraper 1204 and the connecting plate 1201 are driven to move relative to each other through the first connecting member group 1202. When the wire block 120 6 moves to the limit, the controller stops the second micro motor 1210 from working, and the micro hydraulic telescopic rod 1211 drives the connecting plate 1201 to move, and the connecting plate 1201 drives the sponge scraper 1204 to move in the same direction through the first connecting member group 1202, and the sponge scraper 1204 is used to defog one side of the inner wall of the groove mounting frame 5 and the surface of the display meter 4 during the movement. When the humidity sensor senses that the inside of the groove mounting frame 5 reaches the normal temperature, the controller controls the above-mentioned device to reverse or restore the initial movement state, and the steam in the environment is connected to the condensation plate 1302, and the cooling water formed by the steam of the condensation plate 1302 falls into the inside of the collection box 1301 through the through frame 1305 and the filter element 1306. When the thickness sensor senses that the surface thickness of the detection head 2 is thicker, the thickness sensor transmits a signal to the controller, and the thickness sensor controls the operation of the pressurized water pump 1307. The pressurized water pump 1307 transports cooling water to the inside of the delivery pipe group 1308, and the delivery pipe group 1308 transports cooling water to the inside of the connecting pipe group 1309 through the two-way pipe connector 1304. The cooling water entering the connecting pipe group 1309 is sprayed on the detection head 2 through the atomizing nozzle 1310 for cleaning. When the thickness sensor senses that the surface of the detection head 2 reaches the normal thickness, the controller controls the above-mentioned equipment to stop working, thereby completing the entire operation.
