Description

Technical Field

[0001] The invention relates to the technical field of liquid level measurement, and in particular to a side-mounted magnetic float liquid level device for tank body liquid level measurement. Background Art

[0002] The magnetic float level gauge is a liquid level detection instrument widely used in equipment such as towers, tanks, tanks, spherical containers and boilers. Its principle is based on the coupling of buoyancy and magnetism. When the liquid level in the container rises, the buoyancy causes the float with a permanent magnet to rise. The magnetism of the float is transmitted to the external magnetic flip column indicator through coupling, thereby driving the red and white flip columns to flip. The liquid level height is indicated by the change of red and white colors. This intuitive liquid level display method makes the magnetic float level gauge widely used in the industrial field.

[0003] However, the magnetic float level gauge also faces some problems in practical applications. First, in order to ensure that the float can maintain a vertical state, the gap between the tube and the float is designed to be relatively tight. However, when the liquid being detected contains particles, these particles are easily stuck between the float and the tube wall, thereby hindering the free up and down movement of the float, resulting in abnormal or even impossible level measurement. In addition, the weight of the float is fixed. When measuring liquids of different densities, the permanent magnet on the float may not always be consistent with the actual liquid surface, which is prone to reading errors. This error is particularly significant when the liquid density is large or small, affecting the accuracy of the level measurement. Summary of the invention

[0030] like Figures 1 to 6 As shown, an embodiment of the present invention provides a side-mounted magnetic float liquid level device for tank liquid level measurement, which includes a mounting tube 110, a positioning sleeve 210, a magnetic block 230 and an adjustment control.

[0031] The mounting tube 110 is vertically arranged, and the interior of the mounting tube 110 is hollow. The hollow chamber inside the mounting tube 110 is the mounting chamber 111, and the mounting chamber 111 is arranged in a vertical state inside the mounting tube 110. The mounting tube 110 is arranged outside the tank body, and the mounting tube 110 is connected to the tank body through the connecting tube 113. By adjusting the position of the mounting tube 110, when the liquid enters the tank body, the liquid will first enter the mounting chamber 111. When the liquid enters the mounting chamber 111 by a preset amount, the liquid begins to accumulate inside the tank body. A magnetic column indicator 120 is arranged outside the mounting tube 110, and a scale line 130 is arranged outside the mounting block. The scale line 130 is arranged along the length of the mounting tube 110, wherein the zero point of the scale line 130 is at the lower part of the mounting end. Specifically, the magnetic column indicator 120 has a plurality of red columns and a plurality of white columns, each of which can form a complete cylinder, and each of which can form a complete cylinder corresponding to the scale line 130. In a further configuration, in order to ensure that the liquid can smoothly enter the installation cavity 111, the upper end of the installation tube 110 is provided with an air venting pipe 112 connecting the external environment and the installation cavity 111, and the air venting pipe 112 can prevent the air pressure in the installation cavity 111 from changing.

[0032] The positioning sleeve 210 is slidably arranged in the installation cavity 111, and the outer diameter of the positioning sleeve 210 is slightly smaller than the diameter of the installation cavity 111, so as to ensure that the positioning sleeve 210 can smoothly slide up and down in the installation cavity 111. A buoyancy block 220 is arranged inside the positioning sleeve 210, and the buoyancy block 220 is coaxially fixedly arranged with the positioning sleeve 210. When the liquid enters the installation cavity 111, the liquid can give the buoyancy block 220 a certain buoyancy. Under the action of the buoyancy block 220, the positioning sleeve 210 can float on the liquid surface synchronously. By arranging the buoyancy block 220 and the positioning sleeve 210 coaxially, when the buoyancy block 220 drives the positioning sleeve 210 to move upward, the positioning sleeve 210 is not easy to squeeze the inner wall of the installation tube 110, so that the positioning sleeve 210 slides up and down in the installation cavity 111 smoothly enough.

[0033] The magnetic block 230 is slidably disposed inside the buoyancy block 220, and the magnetic block 230 does not directly contact the liquid entering the installation cavity 111. When the magnetic block 230 slides inside the buoyancy block 220, the magnetic flip column indicator 120 can change color. Furthermore, the buoyancy block 220 has a sliding cavity 280 that is not connected to the external environment, and the magnetic block 230 is slidably disposed in the sliding cavity 280. When the magnetic block 230 moves relative to the mounting tube 110, the magnetic block 230 can drive the red and white flip columns in the magnetic flip column indicator 120 to flip. In the initial state, the positioning sleeve 210, the buoyancy block 220, the magnetic block 230, etc. all have a certain gravity. When the liquid just enters the mounting cavity 111, the buoyancy of the liquid on the buoyancy block 220 cannot drive the magnetic block 230 to move relative to the mounting tube 110. When the liquid enters the mounting cavity 111 by a preset amount, the gravity of the positioning sleeve 210, the buoyancy block 220, the magnetic block 230, etc. is exactly equal to the gravity of the liquid on the buoyancy block. The buoyancy of 220 makes the buoyancy block 220 in a state of being about to break away from the lower end surface of the installation cavity 111. As the liquid further enters the tank body, the amount of liquid entering the installation cavity 111 increases at the same time. The buoyancy of the liquid on the buoyancy block 220 can drive the positioning sleeve 210 to gradually move upward in the installation cavity 111. The buoyancy block 220 drives the magnetic block 230 to move relative to the installation tube 110. The magnetic block 230 drives the red and white columns in the magnetic column indicator 120 to flip. The flipped red and white columns are displayed on the scale line 130, thereby clearly indicating the liquid level inside the tank body. A first elastic member is provided between the magnetic block 230 and the buoyancy block 220. The first elastic member is used to maintain the magnetic block 230 at the zero point of the scale line 130 at the beginning. Specifically, the first elastic member is a first spring 240. The first spring 240 is vertically provided. The upper end of the first spring 240 is connected to the lower end of the magnetic block 230. The lower end of the first spring 240 is connected to the lower end of the sliding cavity 280 of the buoyancy block 220. Under the action of the first spring 240, the magnetic block 230 is initially at the zero point of the scale line 130. Since the magnetic block 230 has a certain gravity in the initial state, the first spring 240 is in a squeezed state. When the length of the first spring 240 changes, the position of the magnetic block 230 inside the sliding cavity 280 changes.

[0034] The control unit can adjust the position of the magnetic block 230 inside the buoyancy block 220 according to the density of the liquid entering the installation cavity 111. Specifically, the density of the liquid entering the installation cavity 111 can affect the buoyancy of the buoyancy block 220. Since the gravity of the positioning sleeve 210, the buoyancy block 220, the magnetic block 230, etc. will not change, when the density of the liquid entering the installation cavity 111 changes, the amount of movement of the positioning sleeve 210 driven by the buoyancy block 220 inside the installation cavity 111 will change. At this time, the control unit adjusts the position of the magnetic block 230 inside the buoyancy block 220, thereby improving the accuracy of measuring the liquid level.

[0035] The present invention discloses a side-mounted magnetic buoy liquid level device for measuring the liquid level of a tank body. When measuring the liquid level of the tank body, the installation tube 110 is installed on the outside of the tank body, and the connecting tube 113 is used to connect the installation cavity 111 with the inside of the tank body. When the liquid enters the inside of the tank body, the liquid can enter the installation cavity 111 first, and the liquid entering the inside of the tank body can give a certain buoyancy to the buoyancy block 220. When the liquid begins to gradually remain inside the tank body, the buoyancy block 220 begins to float in the installation cavity 111. When the buoyancy block 220 slides from bottom to top in the installation cavity 111, the magnetic block 230 can flip the red and white columns in the magnetic column indicator 120. When the density of the liquid entering the installation cavity 111 changes, the buoyancy of the buoyancy block 220 on the liquid will change. At this time, the position of the magnetic block 230 is adjusted by the adjustment control, so as to reduce the influence of the change of liquid density on the position of the magnetic block 230, thereby improving the accuracy of measuring the liquid level.

[0036] In one embodiment, the control unit includes a control block 250 and a second elastic member. The control block 250 is slidably connected to the buoyancy block 220, and the control block 250 is coaxially arranged with the buoyancy block 220. The control block 250 is arranged below the magnetic block 230. When the liquid enters the installation cavity 111, the control block 250 is always below the liquid surface, and the control block 250 can directly contact the liquid entering the installation cavity 111. The control block 250 has a cavity inside, and when the liquid contacts the control block 250, the liquid can give the control block 250 a certain buoyancy, and the control block 250 can float on the liquid surface without external interference to the control block 250. A fixed block 290 is provided on the surface of the regulating block 250 close to the magnetic block 230, and the fixed block 290 can be adsorbed by the magnetic block 230. The second elastic member is provided between the regulating block 250 and the buoyancy block 220. Specifically, the sliding cavity 280 is provided at the upper part of the buoyancy block 220, and the lower part of the buoyancy block 220 is hollow. The second elastic member is a second spring 260, and the second spring 260 is vertically provided. The upper end of the second spring 260 is fixedly connected to the lower end of the regulating block 250, and the lower end of the second spring 260 is fixedly connected to the lower end of the buoyancy block 220. In the initial state, when the liquid has not entered the installation cavity 111, the second spring 260 is squeezed and deformed under the action of the gravity of the regulating block 250. When the liquid enters the installation cavity 111, the regulating block 250 gradually moves upward under the action of the buoyancy, and the fixed block 290 on the upper surface of the regulating block 250 gradually approaches the magnetic block 230. At this time, the magnetic force between the magnetic block 230 and the fixed block 290 can make the magnetic block 230 have a tendency to move downward. The density of the liquid entering the installation cavity 111 and the second elastic member can jointly affect the sliding distance of the regulating block 250 inside the buoyancy block 220. Specifically, when the liquid entering the installation cavity 111 changes, the buoyancy of the regulating block 250 will also change, the amount of upward movement of the regulating block 250 will change, the distance between the fixed block 290 on the upper surface of the regulating block 250 and the magnetic block 230 will change, and the magnetic force between the magnetic block 230 and the fixed block 290 will change. Correspondingly, the tendency of the magnetic block 230 to move downward changes, thereby reducing the influence of the liquid density change on the position of the magnetic block 230, thereby improving the accuracy of measuring the liquid level. Furthermore, in the actual production process, the stiffness coefficients of the first spring 240 and the second spring 260 are adjusted, and at the same time, the magnetic force between the magnetic block 230 and the fixed block 290 is regulated to ensure that when the density of the liquid entering the tank body changes, the amount of movement of the magnetic block 230 relative to the buoyancy block 220 can offset the impact of the liquid density difference on the buoyancy block 220, thereby reducing the probability of the magnetic block 230 falling below the liquid surface or the magnetic block 230 floating above the liquid surface.

[0037] In one of the embodiments, a side-mounted magnetic float liquid level device for measuring the liquid level of a tank body also includes a cleaning piece. When particles are present in the liquid entering the installation cavity 111, and the particles hinder the positioning sleeve 210 from sliding in the installation cavity 111, the cleaning piece can clean the particles that hinder the positioning sleeve 210 from sliding in the installation cavity 111, thereby reducing the probability of the particles hindering the positioning sleeve 210 from sliding up and down in the installation cavity 111, thereby ensuring that when the liquid level inside the tank body changes, the positioning sleeve 210 can slide smoothly in the installation cavity 111.

[0038] In one embodiment, the buoyancy block 220 can be divided into an upper part and a lower part according to the positions of the installation of the magnetic block 230 and the regulating block 250, the liquid can enter between the buoyancy block 220 and the positioning sleeve 210, and the liquid level outside the positioning sleeve 210 can be different from the liquid level inside the positioning sleeve 210. The cleaning parts include a plurality of first cleaning plates 310 and a plurality of second cleaning plates 320, the first cleaning plates 310 and the second cleaning plates 320 are slightly elliptical in shape, the plurality of first cleaning plates 310 and the plurality of second cleaning plates 320 are both sleeved on the upper part of the buoyancy block 220, the first cleaning plates 310 and the second cleaning plates 320 are both arranged between the buoyancy block 220 and the positioning sleeve 210, wherein the plurality of first cleaning plates 310 and the plurality of second cleaning plates 320 each have an inner ring and an outer ring, the inner rings of the plurality of first cleaning plates 310 and the plurality of second cleaning plates 320 are fixedly connected to the buoyancy block 220, and the outer rings of the plurality of first cleaning plates 310 and the plurality of second cleaning plates 320 are fixedly connected to the positioning sleeve 210. The first cleaning tray 310 has a first angle with the horizontal plane, the second cleaning tray 320 has a second angle with the horizontal plane, the first angle is not equal to the second angle, the first cleaning tray 310 and the second cleaning tray 320 are alternately arranged in the vertical direction, in the arrangement of multiple first cleaning trays 310 and multiple second cleaning trays 320, in the vertical direction, the first cleaning tray 310 is at the bottom, and one of the second cleaning trays 320 is at the top, for example, in the vertical direction, the first cleaning tray 310 and the second cleaning tray 320 are arranged in an order from bottom to top. The first cleaning disc 310 and the second cleaning disc 320 are both configured in an elliptical shape, and the first one-way valve 312 and the first conduction port 311 are respectively provided at both ends of the long axis of the first cleaning disc 310, wherein the upper end of the long axis of the first cleaning disc 310 is configured as the first conduction port 311, and the lower end of the long axis of the first cleaning disc 310 is configured as the first one-way valve 312, and the second one-way valve 322 and the second conduction port 321 are respectively provided at both ends of the long axis of the second cleaning disc 320, wherein the lower end of the long axis of the second cleaning disc 320 is configured as the second conduction port 321, and the upper end of the long axis of the second cleaning disc 320 is configured as the second one-way valve 322. The first one-way valve 312 and the second conduction port 321 are located in the same vertical line, and the first conduction port 311 and the second one-way valve 322 are located in the same vertical line. In a further configuration, the one-way conducting directions of the first one-way valve 312 and the second one-way valve 322 are the same, and gas or liquid can move from top to bottom through the first one-way valve 312 , but gas or liquid cannot move from bottom to top through the first one-way valve 312 .When there are particles in the liquid entering the installation cavity 111, and the particles hinder the positioning sleeve 210 from sliding in the installation cavity 111, when the liquid entering the installation cavity 111 is gradually increasing, the particles hinder the positioning sleeve 210 from moving from bottom to top. At this time, the liquid level outside the positioning sleeve 210 is higher than the liquid level inside the positioning sleeve 210, and the liquid gradually enters between the positioning sleeve 210 and the buoyancy block 220. Under the action of the first cleaning plate 310 and the second cleaning plate 320, the positioning sleeve 210 and the buoyancy block 220 are The liquid surface is always in an inclined state, which causes the center of gravity of the positioning sleeve 210 and the buoyancy block 220 to shift. Since the angles between the first cleaning plate 310 and the second cleaning plate 320 and the horizontal plane are different, the direction of the center of gravity shift of the positioning sleeve 210 and the buoyancy block 220 is constantly changed. In the process of the center of gravity shift of the positioning sleeve 210 and the buoyancy block 220, the positioning sleeve 210 can squeeze the particles that hinder the positioning sleeve 210 from sliding in the installation cavity 111 until the positioning sleeve 210 slides smoothly in the installation cavity 111.

[0039] Furthermore, when the particles that hinder the sliding of the positioning sleeve 210 in the installation cavity 111 are composed of the accumulation of suspended particles in multiple liquids, during the process of the center of gravity shift of the positioning sleeve 210 and the buoyancy block 220, the positioning sleeve 210 can squeeze the particles that hinder the sliding of the positioning sleeve 210 in the installation cavity 111, so that the volume of the accumulated suspended particles is reduced until the positioning sleeve 210 slides smoothly in the installation cavity 111.

In the arrangement of multiple third cleaning trays 330 and multiple fourth cleaning trays 340, in the vertical direction, the fourth cleaning tray 340 is at the top and one of the third cleaning trays 330 is at the bottom. For example, in the vertical direction, the fourth cleaning tray 340 and the third cleaning tray 330 are arranged in order from top to bottom. The third cleaning disc 330 and the fourth cleaning disc 340 are both configured in an elliptical shape, and the third conducting port 331 and the third one-way valve 332 are provided at both ends of the long axis of the third cleaning disc 330, wherein the third one-way valve 332 is provided at the upper end of the long axis of the third cleaning disc 330, and the third conducting port 331 is provided at the lower end of the long axis of the third cleaning disc 330, and the fourth conducting port 341 and the fourth one-way valve 342 are provided at both ends of the long axis of the fourth cleaning disc 340, wherein the fourth conducting port 341 is provided at the lower end of the long axis of the fourth cleaning disc 340, and the fourth one-way valve 342 is provided at the upper end of the long axis of the fourth cleaning disc 340. The fourth one-way valve 342, the third conducting port 331 and the first one-way valve 312 are located in the same vertical line, and the fourth conducting port 341, the third one-way valve 332 and the first conducting port 311 are located in the same vertical line. In a further configuration, the one-way conducting directions of the third one-way valve 332 and the fourth one-way valve 342 are the same, and the conducting directions of the third one-way valve 332 and the first one-way valve 312 are opposite, so that gas or liquid can move from bottom to top through the third one-way valve 332, but gas or liquid cannot move from top to bottom through the third one-way valve 332.When there are particles in the liquid entering the installation cavity 111, and the particles hinder the positioning sleeve 210 from sliding in the installation cavity 111, when the liquid in the installation cavity 111 is gradually reduced, the particles hinder the positioning sleeve 210 from moving from top to bottom. At this time, the liquid level outside the positioning sleeve 210 is lower than the liquid level inside the positioning sleeve 210, and the liquid gradually leaves the space between the positioning sleeve 210 and the buoyancy block 220. Under the action of the third cleaning plate 330 and the fourth cleaning plate 340, the space between the positioning sleeve 210 and the buoyancy block 220 is The liquid surface is always in an inclined state, which causes the center of gravity of the positioning sleeve 210 and the buoyancy block 220 to shift. Since the angles between the third cleaning plate 330 and the fourth cleaning plate 340 and the horizontal plane are different, the direction of the center of gravity shift of the positioning sleeve 210 and the buoyancy block 220 is constantly changed. In the process of the center of gravity shift of the positioning sleeve 210 and the buoyancy block 220, the positioning sleeve 210 can squeeze the particles that hinder the positioning sleeve 210 from sliding in the installation cavity 111 until the positioning sleeve 210 slides smoothly in the installation cavity 111.

[0041] In one of the embodiments, a liquid inlet 270 connecting the installation cavity 111 and the internal space of the positioning sleeve 210 is provided on the side wall of the positioning sleeve 210. The liquid inlet 270 is provided between the first cleaning plate 310 and the fourth cleaning plate 340. To ensure that the cleaning member can clean the particles that hinder the sliding of the positioning sleeve 210 in the installation cavity 111, the liquid inlet 270 is positioned to ensure that there is a liquid level difference inside and outside the positioning sleeve 210, thereby achieving the center of gravity offset of the positioning sleeve 210.

[0042] In one embodiment, a partition plate is provided inside the buoyancy block 220, and the partition plate can divide the active area of ​​the magnetic block 230 into independent chambers, and the independent chamber is the sliding chamber 280. The lower end of the buoyancy block 220 is set to be hollow, so that the regulating block 250 can directly contact the liquid entering the installation cavity 111, and when the density of the liquid changes, the regulating block 250 can move relative to the buoyancy block 220 in time.

[0043] In one embodiment, the material of the fixing block 290 is any one or more of iron metal, cobalt metal and nickel metal. Specifically, the fixing block 290 can be an iron block, or an iron-cobalt-nickel alloy block. By limiting the material of the fixing block 290, it is ensured that magnetic force can be generated between the fixing block 290 and the magnetic block 230.

[0044] In one embodiment, the positioning sleeve 210, the buoyancy block 220, the first elastic member and the second elastic member are not magnetic, specifically, the positioning sleeve 210, the buoyancy block 220, the first spring 240 and the second spring 260 are not magnetic, thereby preventing interference with the magnetic column indicator 120. In addition, the positioning sleeve 210, the buoyancy block 220, the first spring 240 and the second spring 260 cannot be attracted by magnetism, thereby preventing interference with the magnetic fast, thereby improving the accuracy of measuring the liquid level.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
