Description

Technical Field

[0001] The invention belongs to the field of measurement and control technology, and specifically refers to a radar liquid level measuring device. Background Art

[0002] The radar level meter is a liquid level measurement device based on the principle of time domain reflection. The electromagnetic pulse signal emitted by the pulse transmitter of the radar level meter propagates at the speed of light. When encountering the surface of the medium to be measured, part of the pulse signal of the radar level meter is reflected to form an echo signal. The echo signal returns to the pulse transmitter along the same path. Since the distance between the radar level meter and the surface of the medium to be measured is proportional to the propagation time of the pulse signal between the two, the liquid level height can be calculated based on the obtained propagation time and the speed of light.

[0003] In the production process of zirconium oxide, when the zirconium hydroxide precipitation process is carried out, the solution needs to be stirred with a stirring tank. In the prior art, in order to monitor the material height in the stirring tank, a radar level meter is used as a monitoring device.

[0033] The accompanying drawings are used to provide further understanding of the embodiments of the present invention and constitute a part of the specification. They are used to explain the present invention together with the embodiments of the present invention and do not constitute a limitation of the present invention. DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] In the description of the embodiments of the present invention, it should be understood that terms such as "up", "down", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0036] In the prior art, in the process of preparing zirconium oxide products, it is necessary to first prepare zirconium hydroxide, and then calcine the zirconium hydroxide at high temperature to obtain zirconium oxide. In the process of preparing zirconium hydroxide, in the precipitation process of zirconium hydroxide, it is necessary to use a stirring tank to stir the slurry. During the stirring process, it is necessary to use a radar level measuring device to monitor the slurry in the stirring tank. However, the slurry may splash during the stirring process, which may cause the splashed slurry to splash onto the measuring head of the radar level measuring device, thereby causing inaccurate measurement of the slurry medium.

[0037] like Figures 1 to 5 The present invention is to solve the above problems. An example of the present invention provides a radar liquid level measuring device, including a radar liquid level measuring component 1, a protective steel pipe 2, and a cleaning component 3. The cleaning component 3 is arranged below the protective steel pipe 2.

[0038] The radar level measurement component 1 includes a level meter body 11 and a measuring head 12 . The measuring head 12 is connected to the bottom surface of the level meter body 11 . The protected steel pipe connection 2 is connected to the bottom surface of the level meter body 11 . The measuring head 12 extends into the protective steel pipe 2 .

[0039] The cleaning component 3 includes a supporting base 31, a lifting device 32, a water spraying device, and a cleaning device. The lifting device 32 is connected to the supporting base 31, and the water spraying device and the cleaning device are respectively connected to the lifting device 32. The water spraying device is used to spray the surface of the protective steel pipe 2, and the cleaning device is used to brush the surface of the protective steel pipe 2.

[0040] It should be noted that the positions of the measuring heads 12 of different radar level meters may be different. The protective steel pipe 2 is connected to the measuring head 12 on the radar level meter, and the measuring head 12 is arranged as a whole at the top of the protective steel pipe 2. The protective steel pipe 2 can protect the measuring head 12 from being affected by the splashing liquid, so that the overall measurement is more accurate, and a small air hole can be set on the top of the protective steel pipe 2 to prevent the space between the protective steel pipe 2 and the level meter body 11 from being in a vacuum state when the slurry or solution submerges the bottom surface of the protective steel pipe 2, so that the slurry or solution cannot continue to penetrate into the protective steel pipe 2, thereby causing inaccurate measurement results.

[0041] After the slurry or solution has been measured many times, the slurry may adhere to the protective steel pipe 2. After multiple uses, the protective steel pipe 2 may be corroded or blocked. Therefore, the present invention provides a cleaning component 3 to clean the protective steel pipe 2 after the measurement, thereby extending the service life of the protective steel pipe 2 and preventing blockage.

[0042] In a further implementation of this embodiment, the water spraying device includes a plurality of spray heads 331 , and the plurality of spray heads 331 are respectively and evenly connected to the lifting device 32 , and the plurality of spray heads 331 have the same height.

[0043] The cleaning device includes a plurality of cleaning components 341 , and the plurality of cleaning components 341 are evenly connected to the lifting device 32 , and the plurality of cleaning components 341 have the same height.

[0044] It should be noted that: the nozzle 331 is connected to the water pipe, and the nozzle 331 can be a high-pressure nozzle. The water pipe supplies water to the nozzle 331, and the nozzle 331 sprays the protective steel pipe 2 to wash the materials attached to the protective steel pipe 2. The cleaning component 341 brushes the surface of the protective steel pipe 2 before or after washing, so as to further ensure the surface cleanliness of the protective steel pipe 2.

[0045] In a further implementation of this embodiment, the cleaning component 341 includes a connecting seat 3411, a rotating shaft 3412, and a cleaning brush 3413. The connecting seat 3411 is connected to the lifting device 32, the rotating shaft 3412 is rotatably connected to the connecting seat 3411, the cleaning brush 3413 is connected to the rotating shaft 3412, and the rotating shaft 3412 drives the cleaning brush 3413 to move.

[0046] It should be noted that the cleaning brush 3413 is made of nylon, and the rotating shaft 3412 can be rotatably connected to the connecting seat 3411 through a bearing or other connection method. When in working state, the rotating shaft 3412 is controlled to rotate, thereby driving the cleaning brush 3413 connected to the rotating shaft 3412 to rotate, and the cleaning brush 3413 cleans the protective steel pipe 2.

[0047] In a further implementation of this embodiment, the lifting device 32 includes a first lifting tube 321 and a second lifting tube 322. The first lifting tube 321, the second lifting tube 322 and the protective steel pipe 2 are coaxially arranged, and the diameters of the first lifting tube 321, the protective steel pipe 2 and the second lifting tube 322 increase successively.

[0048] It should be noted that: the protective steel pipe 2 is between the first lifting tube 321 and the second lifting tube 322, and the horizontal distance between the inner wall of the protective steel pipe 2 and the first lifting tube 321 is equal to the horizontal distance between the outer wall of the protective steel pipe 2 and the second lifting tube 322, and the horizontal distances between the multiple nozzles 331 and the inner wall of the protective steel pipe 2 or the outer wall of the protective steel pipe 2 are equal. The nozzle 331 can be detachably connected to the first lifting tube 321 or the second lifting tube 322, which is convenient for disassembly and maintenance when the nozzle 331 is damaged.

[0049] In a further implementation of this embodiment, there are multiple water spray devices and cleaning devices, and the outer walls of the first lifting pipe 321 are respectively connected to the water spray device and the cleaning device, and the inner walls of the second lifting pipe 322 are respectively connected to the water spray device and the cleaning device.

[0050] It should be noted that: at least one water spraying device and a cleaning device are respectively provided on the first lifting tube 321 and the second lifting tube 322. In actual use, in some cases, the protective steel pipe 2 needs to be cleaned more thoroughly to achieve the effect of preventing the erosion of the edge materials on the protective steel pipe 2. Multiple water spraying devices and cleaning devices can be respectively provided on the first lifting tube 321 and the second lifting tube 322.

[0051] In a further implementation of this embodiment, the cleaning component 3 further includes a rotating seat 35 , and the bottom surface of the rotating seat 35 is connected to the supporting base 31 .

[0052] Among them, a first slide rail 351 and a second slide rail 352 are provided on the top surface of the rotating seat 35, the lower end of the first lifting tube 321 is connected to the first slide rail 351, and the lower end of the second lifting tube 322 is connected to the second slide rail 352, and the first slide rail 351 and the second slide rail 352 respectively drive the first lifting tube 321 and the second lifting tube 322 to move.

[0053] It should be noted that the bottom surface of the rotating seat 35 is fixedly connected or can be detached from the supporting base 31 through parts such as threads. The fixed connection has better stability, and the detachable connection is more convenient in case of subsequent maintenance. The track of the first slide rail 351 is cooperated with the first lifting tube 321, and the bottom end of the first lifting tube 321 can be connected to the first slide rail 351 by a detachable connection method such as a snap. When the first slide rail 351 moves, it can drive the first lifting tube 321 to make corresponding movements.

[0054] The track of the second slide rail 352 is matched with the second lifting tube 322 , and the connection method between the bottom end of the second lifting tube 322 and the second slide rail 352 is the same as the connection method between the first track 351 and the first lifting tube 321 .

[0055] Among them, the first slide rail 351 and the second slide rail 352 both adopt circular closed slide rails, and the track of the first slide rail 351 and the track of the second slide rail 352 can be controlled to perform circular motion. When the track of the first slide rail 351 and the track of the second slide rail 352 move, they can respectively drive the first lifting tube 321 and the second lifting tube 322 to rotate, and then the first lifting tube 321 and the second lifting tube 322 can drive the water spraying device and the cleaning device connected to the first lifting tube 321 and the second lifting tube 322 to move.

[0056] like Figure 6 and Figure 7 As shown, in a further implementation of this embodiment, a stirring tank 4 is also included, and the radar liquid level measurement component 1 and the cleaning component 3 are respectively connected in the stirring tank 4.

[0057] The cleaning member 3 further comprises a control vertical plate 36 , which is connected to the mixing tank 4 . A slideway 361 is provided on the side of the control vertical plate 36 away from the mixing tank 4 , and the support base 31 is slidably connected to the control vertical plate 36 via the slideway 361 .

[0058] It should be noted that the support base 31 is connected to the slide 361 by a detachable connection method such as a buckle or a fixed connection method, and the slide 361 on the control vertical plate 36 can move up and down vertically, thereby driving the support base 31 to move up and down vertically.

[0059] Among them, during use, if the distance between the support base 31 and the protective steel pipe 2 is short, it is necessary to make a part of the lifting device 32 extend into the protective steel pipe 2 all the time, which is inconvenient to use; if the distance between the support base 31 and the protective steel pipe 2 is long, the lifting range of the first lifting tube 321 and the second lifting tube 322 of the lifting device 32 is required to be larger, which will increase the overall weight of the lifting device 32, and the stability requirements of the support base 31 are higher, which makes the use cost higher.

[0060] Therefore, a control vertical plate 36 is provided, and a slideway 361 is provided on the control vertical plate 36, which can drive the support base 31 to move vertically up and down, so that the support base 31 can move up and down as a whole during use. During use, the lifting device connected to the support base 31 does not need to extend a part into the protective steel pipe all the time, and the length of the first lifting tube 321 and the second lifting tube 322 does not need to be too long, thereby reducing the requirements for the support base 31 and reducing the cost of use.

[0061] In a further implementation of the present embodiment, the distance between the two water spraying devices arranged on the first lifting tube 321 and the second lifting tube 322 is greater than the wall thickness of the protective steel pipe 2, and the cleaning brushes 3413 arranged on the first lifting tube 321 and the second lifting tube 322 are respectively connected to the inner wall of the protective steel pipe 2 and the outer wall of the protective steel pipe 2.

[0062] It should be noted that the cleaning brush 3413 is made of nylon or other materials. During use, the length of the cleaning brush 3413 can be appropriately greater than the distance between the rotating shaft 3412 and the side wall of the protective steel pipe 2, so that the cleaning brush 3413 can clean the protective steel pipe 2 more cleanly, thereby increasing the service life of the protective steel pipe 2.

[0063] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0064] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.

[0065] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the creative purpose of the embodiments of the present invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
