[0001] This utility model relates to the technical field of gas-ash mixers, and in particular to a gas-ash mixer. Background Technology

[0002] In existing gas-ash mixers, after gas and ash enter the cylinder and mix, it is not conducive to transporting the gas-ash mixture out of the outlet. When the gas source enters the mixing chamber pipe, if the gas source pressure is higher than the conveying pressure, it will cause a brief backflow of conveyed ash. Moreover, the gas-ash mixing efficiency is not high, and the ash is easy to clump together and form clumps, which is not conducive to smooth conveying. Summary of the Invention

A filter screen and a guide plate are fitted between the porous diffuser and the installation pipe. The guide plate is attached to the porous diffuser and has several guide holes inclined towards the outlet. The filter screen is located between the guide plate and the air inlet pipe.

[0006] Preferably, a first clamping flange is fixedly connected to the fixed pipe, an adjusting pipe is sleeved on the porous diffuser pipe, one end of the mounting pipe is connected to the first clamping flange by bolts, and the other end is connected to the adjusting pipe by bolts.

[0016] This application discloses an air-ash mixer. Referring to Figure 1, the air-ash mixer includes a connecting pipe 1, a porous diffuser 2, a fixed pipe 3, an installation pipe 4, and an air inlet pipe 5. The two ends of the porous diffuser 2 are respectively designated as an inlet 21 and an outlet 22. The connecting pipe 1 and the fixed pipe 3 are coaxially connected to the porous diffuser 2, located at the inlet 21 and outlet 22 of the porous diffuser 2, respectively. The outlet 22 of the porous diffuser 2 is an inclined open opening. The porous diffuser 2 has several inlet... A plurality of air inlets 23 are located on the side wall of the top of the porous diffuser 2. An installation tube 4 is sleeved on the outside of the porous diffuser 2 and covers the outside of the air inlets 23. A filter screen 6 and a guide plate 7 are clamped between the porous diffuser 2 and the installation tube 4. The guide plate 7 is attached to the porous diffuser 2 and has a plurality of guide holes 71. The guide holes 71 are inclined toward the discharge port 22. The filter screen 6 is located between the guide plate 7 and the air inlet 5.

[0017] By setting a filter screen 6 and a guide plate 7 between the porous diffuser 2 and the air inlet pipe 5, the airflow can be dispersed, which is conducive to the uniform mixing of materials in the porous diffuser 2 and improves the problem of uneven air-ash mixing. On the other hand, the airflow can be guided towards the outlet 22, which facilitates the output of the mixture from the outlet 22.

[0018] A first clamping flange 31 is fixedly connected to the fixed pipe 3. An adjusting pipe 24 is sleeved on the porous diffuser pipe 2. One end of the mounting pipe 4 is connected to the first clamping flange 31 by bolts, and the other end is connected to the adjusting pipe 24 by bolts. A second clamping flange 25 is also sleeved on the porous diffuser pipe 2. The second clamping flange 25 is connected to the adjusting pipe 24 by bolts.

[0019] The first clamping flange 31, the second clamping flange 25 and the adjusting pipe 24 work together to make the mounting pipe 4 stably connected to the porous diffuser pipe 2.

[0020] The inner wall of the mounting tube 4 is provided with a slot, which is arranged around the circumference of the mounting tube 4. There is one slot at each end of the mounting tube 4. A flexible graphite sealing ring 41 is installed in the slot and is attached to the porous diffuser tube 2.

[0022] A filling groove is provided on the inner wall of the second clamping flange 25, and the filling groove is filled with polyester fiber filler 251. The setting of polyester limiter helps to further improve the sealing performance of the device.

[0023] The implementation principle of the gas-ash mixer in this application embodiment is as follows: First, the external ash conveying system conveys ash into the porous diffuser 2 through the connecting pipe 1, and at the same time, the external gas conveying system conveys gas into the porous diffuser 2 through the air inlet pipe 5, so that the gas and ash are mixed in the porous diffuser 2. The conveying pressure of the ash conveying system is greater than the conveying pressure of the gas conveying system. The gas can be dispersed when passing through the filter screen 6 and the guide air plate 7, so that the dispersed gas and ash can be fully mixed. Since the outlet 22 of the porous diffuser 2 is set with an inclined open opening, the blockage of the mixture at the outlet 22 is improved, so that the mixture can be discharged from the outlet 22 better.
