[0024] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0025] Reference Figure 1 , Figure 2 and Figure 3As shown, a magnesium oxide active homogenizing device comprises a homogenizing cylinder 1, an outlet pipe 4 connected and fixed on the cylinder wall of the homogenizing cylinder 1 for gas discharge, a filter screen 5 built into the air inlet end of the outlet pipe 4, and a rotating rod 2 with one end open and vertically arranged inside the homogenizing cylinder 1, a plurality of stirring rods 3 are arranged around the rod body of the rotating rod 2, and an air jet box (not shown) is also arranged on the homogenizing cylinder 1, the end of the outlet pipe 4 is connected to the magnesium oxide collecting pool containing the aqueous solution, a steam absorption box is arranged in the outlet pipe 4, and a water-absorbing cotton layer is filled in the steam absorption box;

[0026] According to the related content of the magnesium oxide active homogenizing device with the prior art patent announcement number CN208161401U, when magnesium oxide is put into the homogenizing cylinder 1, the personnel can rotate the rotating rod 2 to prompt the stirring rod 3 to fully stir the magnesium oxide, and the homogenizing cylinder 1 is equipped with a jet box, so that an airflow is formed in the inner cavity of the homogenizing cylinder 1 in real time, and the magnesium oxide is pushed by the airflow, so that the magnesium oxide is mixed more evenly and the homogenization effect is improved;

[0027] In addition, the above is only a brief description. As a device disclosed in the prior art, this article does not provide a detailed description of the structure and use principle of the jet box. For specific content, please refer to the above patent documents;

[0028] And in the process of the airflow pushing the magnesium oxide, the generated airflow can finally pass through the outlet pipe 4 into the magnesium oxide collection pool containing the aqueous solution. During this process, the filter screen 5 built into the outlet pipe 4 pre-intercepts a large amount of magnesium oxide in the gas, so that a large amount of magnesium oxide remains inside the homogenizing cylinder 1, thereby increasing the utilization of magnesium oxide. In addition, a small amount of magnesium oxide can be passed into the magnesium oxide collection pool along with the gas to react with the aqueous solution, thereby reducing the pollution of the external environment of the homogenizing cylinder 1 by the leaked magnesium oxide.

[0029] Although the above embodiment reduces the leakage of magnesium oxide along the outlet pipe 4 by inserting the filter 5 in the outlet pipe 4, in practice, the filter 5 intercepts magnesium oxide for a long time, and the surface of the filter 5 is easily attached with a large amount of magnesium oxide, which seriously blocks a large number of filter holes on the filter 5 and affects the flow rate of gas in the outlet pipe 4;

[0030] In view of this, refer to Figure 2 and Figure 3 As shown, it is worth noting that it also includes a cleaning mechanism for reducing the amount of magnesium oxide attached to the surface of the filter 5;

[0031] The cleaning mechanism includes a brush plate 6 vertically attached to the surface of the filter screen 5, a telescopic cylinder 7 connected and fixed to the rod body of the rotating rod 2, and a push-pull component arranged between the telescopic cylinder 7 and the brush plate 6. A power component cooperating with the push-pull component is arranged in the inner cavity of the rotating rod 2;

[0032] By setting the cleaning mechanism, when it is used for a long time, if a large amount of magnesium oxide is attached to the surface of the filter screen 5, which affects the flow rate of the gas in the outlet pipe 4, the power component in the cleaning mechanism can act on the push-pull component to push and pull the brush plate 6, so that the brush plate 6 is close to the inner wall of the homogenizing cylinder 1. In this way, during the rotation of the rotating rod 2, the brush plate 6 can clean the surface of the filter screen 5 and reduce the amount of magnesium oxide attached to the filter screen 5, thereby effectively maintaining the flow rate of the gas in the outlet pipe 4;

[0033] And when the gas flow rate inside the gas outlet pipe 4 returns to normal, the push-pull component in the cleaning mechanism can pull the brush plate 6, prompting the brush plate 6 to be quickly separated from the homogenizing cylinder 1 and the filter screen 5, so as to prevent the brush plate 6 from scratching the inner wall of the homogenizing cylinder 1 or the filter screen 5 in real time with the rotating rod 2 during the magnesium oxide stirring process, which will cause serious wear over time.

[0034] Specifically, refer to Figure 3 As shown, it is worth noting that the push-pull component includes a slide 8 slidably arranged in the inner cavity of the telescopic cylinder 7 and a pull rod 9 vertically fixed on one side of the slide 8. The end of the pull rod 9 passes through the telescopic cylinder 7 and is detachably provided with a receiving rod 10. The end of the receiving rod 10 is fixedly connected to the brush plate 6.

[0035] The power component includes a supply rotation seat 17 fixed on the top surface of the homogenizing cylinder 1 through a bracket and an electromagnet 14 installed on the bottom surface of the supply rotation seat 17. The open end of the rotating rod 2 rotates to pass through the homogenizing cylinder 1 and is rotatably connected to the supply rotation seat 17. The electromagnet 14 is located in the rotating rod 2, and a movable sheet 11 is slidably arranged above the inner cavity of the rotating rod 2. A magnet block 13 corresponding to the electromagnet 14 is installed on one side of the movable sheet 11. A pull rope 12 is fixed on the other side of the movable sheet 11. The end of the pull rope 12 penetrates into the telescopic cylinder 7 and is fixedly connected to the other side of the sliding sheet 8.

[0036] A spring 18 is sleeved on the rod body of the pull rod 9 located inside the telescopic cylinder 7, one end of the spring 18 is fixedly connected to the slide 8, and the other end of the spring 18 is fixedly connected to the inner wall of the telescopic cylinder 7;

[0037] When the gas flow in the outlet pipe 4 is normal, the electromagnet 14 is connected to the power supply, and the magnet block 13 can be attracted, causing the movable sheet 11 to slide up quickly, so that the movable sheet 11 pulls the slide 8 through the pull rope 12, so that the slide 8, the pull rod 9 and the receiving rod 10 pull the brush plate 6 synchronously as a whole, so that the brush plate 6 is separated from the inner wall of the homogenizing cylinder 1 or the filter screen 5, so as to prevent the brush plate 6 from scratching the inner wall of the homogenizing cylinder 1 or the filter screen 5 in real time during the rotation of the rotating rod 2, thereby reducing the wear of the brush plate 6;

[0038] During the process of sliding the slide plate 8 on the inner side of the telescopic cylinder 7 pulled by the pull rope 12, the slide plate 8 can stretch the spring 18 to deform. In this way, when the gas flow inside the outlet pipe 4 is abnormal, the electromagnet 14 is disconnected from the power supply, and the force on the magnet block 13 disappears. The slide plate 8 can use the pull rod 9 and the receiving rod 10 to push the brush plate 6 back under the elastic force of the spring 18, so that the brush plate 6 is attached to the inner wall of the homogenizing cylinder 1 or the filter screen 5, and the cleaning operation on the surface of the filter screen 5 continues.

[0039] Further, refer to Figure 3 As shown, it is worth noting that the power component also includes a fixed ring plate 15 which is arranged in a circular shape below the movable plate 11 and is fixedly connected to the inner wall of the rotating rod 2. Two telescopic rods 16 are symmetrically arranged between the fixed ring plate 15 and the movable plate 11. One end of the telescopic rod 16 is fixedly connected to the fixed ring plate 15, and the other end of the telescopic rod 16 is fixedly connected to the movable plate 11. The pull rope 12 is inserted and retracted into the inner side of the fixed ring plate 15.

[0040] By setting the telescopic rod 16 , during the lifting and lowering process of the movable sheet 11 , the telescopic rod 16 can be synchronously telescoped and adjusted, thereby effectively limiting the moving trajectory of the movable sheet 11 and ensuring the stability of the movable sheet 11 during movement.

[0041] Further, refer to Figure 3 and Figure 4 As shown, it is worth noting that a mounting groove adapted to the receiving rod 10 is provided on one end of the pull rod 9 facing the receiving rod 10, a fixing stud 19 is vertically fixed on the inner wall at the bottom end of the mounting groove, the end of the fixing stud 19 penetrates the receiving rod 10 and is threadedly connected with a fixing nut 20, and the fixing nut 20 abuts against the receiving rod 10;

[0042] By setting the fixing stud 19 and the fixing nut 20, if the brush surface of the brush plate 6 is worn after a certain period of use, the person only needs to simply turn the knob of the fixing nut 20 to make the fixing nut 20 withdraw from the rod of the fixing stud 19 under the threaded structure, thereby releasing the fixing effect of the receiving rod 10 in the installation groove, making it convenient for personnel to separately replace the receiving rod 10 and the brush plate 6 as a whole.

[0043] Furthermore, it is worth noting that the gas outlet pipe 4 is built with a flow meter, and the flow meter is electrically connected to the electromagnet 14;

[0044] By setting the flow meter, the flow rate of the gas inside the gas outlet pipe 4 can be monitored during the homogenization of magnesium oxide. When the gas flow rate in the gas outlet pipe 4 is abnormal, the power supply of the electromagnet 14 is disconnected.

[0045] Further, refer to Figure 2 As shown, it is worth noting that two feeding windows are symmetrically provided on the top surface of the homogenizing cylinder 1, and a sealing plate 21 hingedly connected to the top surface of the homogenizing cylinder 1 is provided outside the feeding window;

[0046] The provision of the feeding window not only facilitates personnel to feed magnesium oxide raw materials into the inner cavity of the homogenizing cylinder 1, but also facilitates personnel to dismantle and replace the brush plate 6 and the receiving rod 10 as a whole in the inner cavity of the homogenizing cylinder 1 through the feeding window;

[0047] Furthermore, by providing the sealing plate 21, after the personnel have finished feeding the materials into the inner cavity of the homogenizing cylinder 1, the feeding window can be sealed, thereby preventing the magnesium oxide raw material from leaking out of the feeding window in large quantities.

[0048] Further, refer to Figure 2 As shown, it is worth noting that it also includes a rotation supply mechanism for driving the rotating rod 2 to rotate;

[0049] The rotation mechanism includes a motor 22 mounted on the top surface of the homogenizing cylinder 1 through a bracket, and the output shaft of the motor 22 and the rod body of the rotating rod 2 are both tightly sleeved with pulleys, and a transmission belt 23 is connected between the two pulleys;

[0050] Through the arrangement of the transmission belt 23 and the motor 22 , when the motor 22 is turned on, the output shaft of the motor 22 can be driven by the transmission belt 23 to drive the motor 22 , thereby providing a rotational force for the rotating rod 2 .
