Description

Technical Field

[0001] The utility model relates to the technical field of alkali liquid tanks, in particular to an auxiliary stirring device for an alkali liquid tank. Background Art

[0002] The alkali liquid tank is an important equipment for treating hydrogen sulfide contained in coal gas. The alkali liquid tank dissolves sodium carbonate and then pumps the dissolved sodium carbonate into the lean liquid tank through a centrifugal pump to remove hydrogen sulfide from the coal gas.

[0003] The lye tank is equipped with a stirring device and a liquid level meter. The stirring device can ensure that the sodium carbonate particles are fully dispersed in the water to promote its dissolution process. The liquid level meter can monitor the liquid level of the solution in real time to ensure that the appropriate amount of water or sodium carbonate is added at the appropriate time to maintain the required solution concentration and liquid level.

[0004] However, in the actual operation of the alkali liquid tank, the stirring device will produce large liquid level fluctuations while fully stirring, which will cause obvious fluctuations in the reading of the liquid level meter, resulting in inaccurate values. In addition, due to the uncertainty of the liquid level height inside the alkali liquid tank, and the position of the stirring blade in the alkali liquid tank is usually fixed, when the solution in the alkali liquid tank just soaks the lower half of the stirring blade, and the upper half is above the liquid surface, stirring at this time will further increase the amplitude and frequency of liquid level fluctuations. In this case, it will be difficult for the liquid level meter to accurately reflect the actual liquid level in the alkali liquid tank, resulting in the problem of being unable to replenish materials in time, which directly affects the normal operation of the equipment.

DETAILED DESCRIPTION

[0026] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] See also Figure 1-8As shown, the utility model provides an auxiliary stirring device for an alkali liquid tank, comprising a cover plate 2, a driving assembly and a telescopic rod 6. The cover plate 2 is buckled on the upper surface of the alkali liquid tank 1, a feeding pipe is fixedly connected to the top of one side of the alkali liquid tank 1, a water inlet pipe is fixedly connected to the top of the other side of the alkali liquid tank 1, and a discharge pipe is fixedly connected to the bottom of the front side of the alkali liquid tank 1. A center hole 21 is penetrated through the center position of the upper surface of the cover plate 2, and a stirring shaft 3 is rotatably connected to the inside of the center hole 21 through a bearing. The driving assembly is used to drive the stirring shaft 3 to rotate, and the driving assembly is located above the cover plate 2, a slide groove 32 is penetrated through the inside of the stirring shaft 3, a slider 5 is slidably connected to the inside of the slide groove 32, a plurality of groups of fixing rings 51 are equidistantly fixedly connected to the outside of the slider 5, a stirring blade 52 is fixedly connected to the outside of the fixing ring 51, and the telescopic rod 6 is fixedly connected to the outside of the fixing ring 51 through a fixed hole 21. The fixed frame 34 is fixedly connected to the top of the stirring shaft 3, and the lower end of the telescopic rod 6 is connected to the driving rod 61. The upper surface of the stirring shaft 3 is penetrated by a through hole 33, and the through hole 33 is connected to the slide groove 32. The end of the driving rod 61 passes through the inside of the through hole 33 and is fixedly connected to the upper surface of the slider 5. Four groups of mounting holes 22 are equidistantly provided on the outer side of the upper surface of the cover plate 2. The upper surface of the mounting holes 22 is fixedly connected to a connecting ring seat 7. The insides of the four groups of mounting holes 22 are all connected to a float rod 8. The upper end of the float rod 8 is fixedly connected to a liquid level monitor, and a float is slidably connected to the outer side of the float rod 8. A fixed seat 81 is fixedly connected to the outer side of the float rod 8 and located below the liquid level monitor. The fixed seat 81 is detachably connected to the upper surface of the connecting ring seat 7, and the driving assembly and the telescopic rod 6 are electrically connected to the main controller.

[0028] The utility model can adjust the height of the stirring blades 52 according to the actual solution height in the alkali solution tank 1, ensuring that a group of stirring blades 52 closest to the liquid surface is located above the solution surface or completely enters the solution, thereby effectively avoiding the problem of liquid level fluctuation caused by stirring.

[0029] In addition, during the stirring process, four sets of liquid level monitors are distributed in the four corners of the alkali liquid tank 1 to monitor the liquid level height in the alkali liquid tank 1 in real time. When the liquid level values ​​transmitted to the master controller by the four sets of liquid level monitors differ greatly, it indicates that the liquid level in the alkali liquid tank 1 fluctuates greatly. The master controller will adjust the speed of the driving component accordingly until the liquid level values ​​transmitted to the master controller by the four sets of liquid level monitors tend to be relatively stable, at which time the liquid fluctuation in the alkali liquid tank 1 is effectively controlled.

[0030] It should be noted that the telescopic rod 6 can be an electric push rod, and when the stirring shaft 3 rotates, the electric push rod will also rotate synchronously. At this time, a conductive slip ring can be installed above the electric push rod, and the conductive slip ring can achieve electrical connection during the rotation without entanglement or disconnection.

[0031] Furthermore, the driving assembly includes a reduction motor 4, which is fixedly connected to the top of the cover plate 2 through a fixing frame 2 42, and the output shaft of the reduction motor 4 is fixedly connected to a gear 2 41, and the outer side of the stirring shaft 3 and located above the cover plate 2 is fixedly connected to a gear 1 31, and the gear 2 41 is meshed with the gear 1 31; in this technical solution, the reduction motor 4 is used to drive the gear 2 41 to rotate through the output shaft, and the gear 2 41 in turn drives the gear 1 31 meshed therewith to rotate, thereby indirectly driving the stirring shaft 3 to rotate. By using the reduction motor 4 as the driving source, the speed of the stirring shaft 3 can be controlled by adjusting the speed of the reduction motor 4 as needed. Secondly, this indirect drive method can provide more stable and reliable power transmission, and reduce the vibration and noise caused by direct transmission.

[0032] Furthermore, guide grooves 321 are provided on both sides of the slide groove 32, and guide blocks 53 are fixedly connected on both sides of the slider 5, and the guide blocks 53 are slidably connected inside the guide groove 321 on the corresponding side; when adjusting the height of the stirring blade 52, the telescopic rod 6 controls the driving rod 61 to perform telescopic movement, thereby driving the slider 5 to move vertically in the slide groove 32. When the slider 5 moves, it will drive the guide blocks 53 on both sides of the slider 5 to slide inside the guide groove 321, and the guide groove 321 provides a guiding and limiting function for the guide blocks 53, which can ensure the stability of the movement of the slider 5.

[0033] Furthermore, both sides of the connecting ring seat 7 are fixedly connected with the insertion rail 71, and both sides of the fixing seat 81 are fixedly connected with the slide rail 82. The side of the slide rail 82 away from the fixing seat 81 is fixedly connected with the fixing plate 83. The surface of the fixing plate 83 is penetrated with a threaded hole 831. The internal thread of the threaded hole 831 is connected with an adjusting threaded rod 84. The internal sliding connection of the slide rail 82 is connected with a movable block 85. The lower surface of the movable block 85 is fixedly connected with an insertion block 851, and the end of the adjusting threaded rod 84 is fixedly connected to one side of the insertion block 851. When the connecting ring seat 7 and the fixing seat 81 are fixed, the insertion block 851 is inserted into the insertion rail 71 on the corresponding side; by manually rotating the adjusting threaded rod 84, the insertion block 851 can be pushed into the insertion rail 71, thereby achieving the fixation between the connecting ring seat 7 and the fixing seat 81. This simple and quick fixing method allows the float rod 8 to be quickly disassembled and assembled when it is inspected and maintained, thereby reducing the time and workload required for maintenance.

[0034] Furthermore, a single set of fixing rings 51 is fixedly connected with four sets of stirring blades 52, and the angle between two adjacent sets of stirring blades 52 is ninety degrees; the four sets of stirring blades 52 can ensure that the various components of the solution are fully mixed and evenly distributed during the stirring process. The ninety-degree angle between two adjacent sets of stirring blades 52 can make each set of stirring blades 52 complement each other during stirring, effectively improving the stirring efficiency.

[0035] Furthermore, the stirring blade 52 is inclined; the inclined stirring blade 52 can push the solution upward from the bottom, expanding the stirring range of the solution, so that the liquid in the alkali solution tank 1 can be better mixed. The inclined stirring blade 52 can more effectively utilize the stirring force and reduce the energy consumption required for stirring.

[0036] Working principle: First, when installing the float rod 8, the float rod 8 can be inserted into the connection ring seat 7, and then extended into the alkali liquid tank 1 after passing through the installation hole 22, until the lower surface of the fixing seat 81 fits with the upper surface of the connection ring seat 7. Then adjust the relative position between the fixing seat 81 and the connection ring seat 7 so that the insertion rail 71 and the slide rail 82 are in a parallel state. Then manually rotate the adjustment threaded rod 84, and the adjustment threaded rod 84 drives the plug 851 to move toward the insertion rail 71 until the plug 851 is completely inserted into the insertion rail 71, so that the installation and fixation of the float rod 8 is completed.

[0037] In the second step, sodium carbonate and water are added into the alkali solution tank 1 through the feeding pipe and the water inlet pipe.

[0038] The third step is that after the feeding is completed and before stirring, the liquid level monitor will transmit the real-time liquid level in the alkali liquid tank 1 to the main controller, and the main controller will adjust the height of the stirring blades 52 according to the liquid level height in the alkali liquid tank 1 to ensure that the group of stirring blades 52 closest to the liquid surface is located above the liquid surface or completely enters the solution, thereby avoiding the problem of large liquid surface fluctuations caused by stirring. The specific operation is: the main controller controls the operation of the telescopic rod 6, and the telescopic rod 6 controls the driving rod 61 to perform telescopic movement, thereby driving the slider 5 connected to the lower surface of the driving rod 61 to slide inside the slide groove 32, and the slider 5 drives the stirring blades 52 to adjust their positions through the fixing ring 51.

[0039] The fourth step is to control the reduction motor 4 to operate through the main controller. The reduction motor 4 drives the gear 2 41 to rotate through the output shaft. The gear 2 41 engages with the gear 1 31, and indirectly drives the stirring blade 52 on the outer side of the stirring shaft 3 to stir the solution raw materials in the alkali solution tank 1.

[0040] In the fifth step, during stirring, the four sets of liquid level monitors will monitor the liquid level height inside the alkali liquid tank 1 in real time. When the liquid level values ​​transmitted to the main controller by the four sets of liquid level monitors differ greatly, it means that the liquid level in the alkali liquid tank 1 fluctuates greatly. At this time, the main controller will adjust the speed of the reduction motor 4 to reduce its speed until the liquid level values ​​transmitted to the main controller by the four sets of liquid level monitors tend to be relatively stable, so that the liquid level fluctuation can be controlled in time.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
