Technical Field

[0001] The utility model relates to the field of drug adding devices, in particular to a quantitative drug adding device. Background Art

[0002] In the non-ferrous metal smelting industry, the radiation part of the flash furnace waste heat boiler often has soot and soot accumulation problems. Removing the soot scale in this area can avoid deformation and damage to the boiler caused by uneven heating of the boiler radiation part due to soot accumulation, and can also avoid the formation of new soot scale. At the same time, it also avoids the damage to the boiler body caused by the previous method of blasting to remove soot scale, greatly reducing operating costs and increasing economic benefits. At present, the industry mainly uses quantitative dosing devices to quantitatively add drugs to the soot scale area in order to remove soot scale. This type of quantitative dosing device can accurately control the dosage of the drug and add the drug according to the preset dosage.

[0003] However, in actual use, the stirring component of this type of quantitative dosing device is mostly one-way stirring, and the fusion efficiency of the soot removal inhibitor and water is low. It takes a long time to complete the full fusion of the soot removal inhibitor powder and water. In order to further improve the fusion efficiency of the soot removal inhibitor and water, based on this, a quantitative dosing device capable of full stirring is provided. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 In the embodiment of the utility model, a quantitative dosing device includes a base 1, an outer barrel 2, a cover body 3, and a motor 4. The bottom wall of the outer barrel 2 is rotatably connected to a rotating shaft 5. The outer wall of the rotating shaft 5 is fixedly connected to a first threaded piece 7, a second threaded piece 8, and a third threaded piece 9 in sequence from bottom to top. The first threaded piece 7, the second threaded piece 8, and the third threaded piece 9 are used to bring the solution inside the base 1 into the inside of the ring 10;

[0023] The bottom wall of the cover body 3 is fixedly connected with a circular ring 10, and three storage grooves 15 are opened in the circular ring 10 along the vertical direction. The first thread piece 7, the second thread piece 8, and the third thread piece 9 are respectively distributed in the three storage grooves 15;

[0024] The outer wall of the ring 10 is fixedly connected with a first round rod 11, a second round rod 12, and a third round rod 13 in sequence from bottom to top, and the first round rod 11, the second round rod 12, and the third round rod 13 are respectively provided with concave holes 14 for the solution to flow out;

[0025] The bottom outer wall of the rotating shaft 5 is fixedly connected with a stirring blade 6, and the stirring blade 6 is used to stir the liquid flowing out of the first round rod 11, the second round rod 12, and the third round rod 13;

[0026] Two groups of the first round rod 11, the second round rod 12 and the third round rod 13 are symmetrically distributed on the outer wall of the ring 10, and the two groups of the first round rod 11, the second round rod 12 and the third round rod 13 are respectively connected to the three storage grooves 15;

[0027] The stirring blade 6 is similar to a "concave"-shaped structure when viewed from the front, and a plurality of protrusions for stirring are sequentially distributed inside the "concave" shape, and the protrusions are staggered with the first round rod 11, the second round rod 12, and the third round rod 13 along the vertical direction;

[0028] The height of the ring 10 is smaller than the height of the outer barrel 2, and there is a gap between the bottom of the ring 10 and the bottom of the inner wall of the outer barrel 2, so that the first threaded sheet 7, the second threaded sheet 8, and the third threaded sheet 9 can bring the solution in the outer barrel 2 into the inside of the ring 10;

[0029] The outer barrel 2 is installed on the inner side of the base 1, and the cover body 3 is fixed to the top of the outer barrel 2. The upper wall of the cover body 3 is provided with a motor 4 that passes through the inside of the cover body 3 and is fixedly connected to the rotating shaft 5. The upper wall of the motor 4 is fixedly connected with a solid block, and the bottom wall of the solid block is fixedly connected to the upper wall of the cover body 3.

[0030] In this embodiment: when the quantitative dosing device is actually used, first open the lid of the feed port above the cover body 3, then pour the powdered medicine to be stirred into the interior of the outer barrel 2, then fill the interior of the outer barrel 2 with water, and then cover the lid of the feed port, then start the motor 4, and the motor 4 drives the rotating shaft 5 to rotate, and the rotating shaft 5 starts to drive the stirring blade 6, the first threaded blade 7, the second threaded blade 8, and the third threaded blade 9 to rotate synchronously. During this period, as the first threaded blade 7, the second threaded blade 8, and the third threaded blade 9 rotate, the first threaded blade 7, the second threaded blade 8, and the third threaded blade 9 start to drive the solution outside the ring 10 into the interior of the ring 10;

[0031] During this period, the solution continuously enters the interior of the ring 10 and continuously moves upward inside the ring 10. As the diameters of the first threaded sheet 7, the second threaded sheet 8, the third threaded sheet 9 and the three storage grooves 15 decrease from bottom to top, the upward water flow will be divided, and part of the water will enter the first round rod 11 and the second round rod 12. The water flowing to the uppermost end will enter the interior of the third round rod 13, and finally flow out through the concave holes 14 on the first round rod 11, the second round rod 12 and the third round rod 13, thereby mixing with the liquids at different heights inside the outer barrel 2.

[0032] At the same time, the synchronously rotating stirring blades 6 stir the solutions leaking from the first round rod 11, the second round rod 12, and the third round rod 13 respectively. At this time, the solution in the outer barrel 2 is synchronously stirred in both horizontal and vertical directions. Through the cooperation of the above parts, the purpose of fully stirring the solution inside the outer barrel 2 is achieved. Different from the traditional unidirectional stirring, the mixing efficiency of the solution is effectively improved.

[0033] Please refer to Figures 2-3 The inner wall diameters of the three storage grooves 15 decrease from bottom to top, and the diameters of the first thread piece 7 , the second thread piece 8 , and the third thread piece 9 respectively match the inner wall diameters of the three storage grooves 15 .

[0034] In this embodiment: in order to achieve the stratified discharge of the solution inside the ring 10, the stratified gap diameter of the storage groove 15 is set to match the first threaded sheet 7, the second threaded sheet 8, and the third threaded sheet 9, so that the first threaded sheet 7, the second threaded sheet 8, and the third threaded sheet 9 can drive the solution of the corresponding layers to be discharged along the internal recessed holes 14 of the first round rod 11, the second round rod 12, and the third round rod 13, respectively, so that the stirring sheet 6 can stir the solution in the outer barrel 2 in both horizontal and vertical directions, thereby achieving the purpose of fully stirring the solution.

[0035] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
