[0014] Compared with the prior art, the beneficial effects of this utility model are: the vertical kiln ejector unclogging device not only realizes the function of facilitating the cleaning of dust in the channel, but also realizes the function of air pressure monitoring and feedback, and also realizes the function of ring pipe support and reinforcement;

[0015] (1) By setting up an air tank, a drain valve, an inlet valve, an outlet valve, a solenoid valve, a main pipe, a three-way connector, a first branch pipe, a first compressed air ring pipe, a first inclined jet pipe, a second branch pipe, a second compressed air ring pipe, and a second inclined jet pipe, when in use, the air compressor is connected to the inlet valve of the air tank to supply air to the air tank.

The solenoid valve controls the jet frequency to achieve the effect of pulse jet blowing, and realizes the function of easy cleaning of dust in the channel.

[0016] (2) By setting up a support frame, PLC controller, speaker, gas pressure sensor and sensor wiring, when in use, as the high-pressure gas in the air tank is continuously consumed, the internal air pressure will also drop synchronously. The gas pressure sensor monitors the air pressure in the air tank in real time.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figure 1-5 A vertical kiln ejector unclogging device includes an air tank 1, a drain valve 2 at the bottom of the air tank 1, an air inlet valve 3 on the right side of the air tank 1, an air outlet valve 4 fixedly connected to the top of the air tank 1, a main pipe 6 vertically arranged above the air outlet valve 4, a solenoid valve 5 installed between the air outlet valve 4 and the main pipe 6, a tee connector 7 fixedly connected to the top of the main pipe 6, a first compressed air ring pipe 9 and a second compressed air ring pipe 12 respectively arranged on the left side of the main pipe 6, a first branch pipe 8 fixedly connected between the tee connector 7 and the first compressed air ring pipe 9, four sets of first oblique jet pipes 10 obliquely welded to the bottom of the first compressed air ring pipe 9, a second branch pipe 11 fixedly connected between the tee connector 7 and the second compressed air ring pipe 12, and four sets of second oblique jet pipes 13 obliquely welded to the bottom of the second compressed air ring pipe 12.

[0026] The air tank 1, air outlet valve 4, solenoid valve 5, and main pipe 6 are internally connected. The inner diameters of air outlet valve 4 and main pipe 6 are the same. The specifications of the first branch pipe 8 and the second branch pipe 11 are the same. The pipe diameters of the first branch pipe 8 and the second branch pipe 11 are smaller than the pipe diameter of the main pipe 6. The shape and size of the first compressed air ring pipe 9 and the second compressed air ring pipe 12 are the same. The vertical center lines of the first compressed air ring pipe 9 and the second compressed air ring pipe 12 coincide. The internal connections of the first compressed air ring pipe 9 and the first inclined jet pipe 10 are connected. The first inclined jet pipe 10 is inserted obliquely into the vertical kiln ejector channel. The internal connections of the second compressed air ring pipe 12 and the second inclined jet pipe 13 are connected. The second inclined jet pipe 13 is inserted obliquely into the vertical kiln ejector channel. The dust inside the channel is cleaned by jetting to prevent it from accumulating and clogging the wall.

[0027] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the air tank 1 can stabilize the air source pressure. Compressed air enters the first compressed air ring pipe 9 and the second compressed air ring pipe 12 through the main pipe 6, the first branch pipe 8 and the second branch pipe 11 respectively. The airflow is then blown into the inside of the injector channel through the corresponding first inclined jet pipe 10 and the second inclined jet pipe 13 to blow off the dust attached to the inner wall of the channel. The solenoid valve 5 controls the jetting frequency to achieve the effect of pulse jetting.

[0028] A support frame 14 is fixedly connected to the top left side of the gas tank 1. A PLC controller 15 is installed at the top of the support frame 14. A speaker 16 is fixedly connected to the right side of the PLC controller 15. A gas pressure sensor 17 is set on the left side of the PLC controller 15. A sensor wiring 18 is movably connected between the PLC controller 15 and the gas pressure sensor 17. The bottom end of the gas pressure sensor 17 passes through the top of the gas tank 1 and extends into it. The PLC controller 15, the speaker 16, and the gas pressure sensor 17 are electrically connected to facilitate the monitoring of gas pressure.

[0029] Specifically, such as Figure 1 and Figure 4 As shown, the gas pressure sensor 17 monitors the gas pressure in the gas tank 1 in real time. When the pressure is lower than the preset threshold, the speaker 16 issues a reminder, and the staff turns on the air compressor to replenish it. The PLC controller 15, the speaker 16, and the gas pressure sensor 17 are electrically connected. This technology is existing technology, so it will not be described in detail.

[0030] The first compressed air ring pipe 9 and the second compressed air ring pipe 12 are respectively provided with inner fixing rings 19. Multiple sets of support platforms 20 are welded to the outer wall of the inner fixing ring 19. The end of the support platform 20 is welded with a ring pipe connecting clamp 21. The first compressed air ring pipe 9 and the second compressed air ring pipe 12 are respectively fixedly connected to the ring pipe connecting clamp 21. The inner fixing ring 19 is fixedly connected to the outside of the vertical kiln ejector channel to facilitate the formation of support for the ring pipe.

[0031] Specifically, such as Figure 1 and Figure 5 As shown, the inner fixing ring 19, the support platform 20 and the ring pipe connecting clamp 21 form a support frame, which supports the first compressed air ring pipe 9 and the second compressed air ring pipe 12, and avoids large-scale shaking when the high-pressure airflow surges.

[0032] Working Principle: In use, the air compressor first connects to the air inlet valve 3 of the air tank 1 to supply air to the air tank 1. The air tank 1 can stabilize the air source pressure. Compressed air enters the first compressed air ring pipe 9 and the second compressed air ring pipe 12 through the main pipe 6, the first branch pipe 8, and the second branch pipe 11, respectively. The airflow is then blown into the injector channel through the corresponding first inclined jet pipe 10 and the second inclined jet pipe 13, blowing off the dust adhering to the inner wall of the channel. The solenoid valve 5 controls the jetting frequency to achieve the effect of pulse jetting. As the high-pressure gas in the air tank 1 is continuously consumed, its internal air pressure will also drop synchronously. The gas pressure sensor 17 monitors the air pressure in the air tank 1 in real time. When the pressure is lower than the preset threshold, the speaker 16 sounds an alarm, and the operator turns on the air compressor to replenish the pressure. The first compressed air ring pipe 9 and the second compressed air ring pipe 12 are fixed outside the injector channel. The inner fixing ring 19, the support platform 20 and the ring pipe connecting clamp 21 form a support frame to support the first compressed air ring pipe 9 and the second compressed air ring pipe 12, so as to avoid large-scale shaking when the high-pressure airflow surges.
