[0020] 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.

[0021] See also Figures 1 to 3 A combined material-gas separation device comprises a cyclone material-gas separator 1, characterized in that a cartridge material-gas separator 2 is arranged inside the cyclone material-gas separator 1, a feed port 3 is fixedly connected to an outer wall on one side of the cyclone material-gas separator 1, an air outlet 4 is fixedly connected to an outer wall on the other side of the cyclone material-gas separator 1, an ash collecting hopper 9 is fixedly connected to the bottom of the cyclone material-gas separator 1, a head 13 is fixedly installed on the top of the cyclone material-gas separator 1, the cartridge material-gas separator 2 comprises a material guide cone 10, a material guide plate 11, and a cartridge body 12, the material guide cone 10 is arranged inside the cyclone material-gas separator 1, at least one material guide plate 11 is arranged at the inner bottom of the material guide cone 10, and at least one cartridge body 12 is arranged at the inner top of the material guide cone 10;

[0022] When the dust-laden airflow enters the cyclone gas separator 1 along the tangential direction of the feed port 3, it makes a spiral motion downward along the gap between the outer cylinder and the filter gas separator 2. After spiral centrifugation, the material falls and hits the guide cone 10 and the guide plate 11, causing it to settle down. A small amount of material rises with the air into the filter cartridge gas separator 2. After being filtered and separated by the filter cartridge body 12, the clean air is filtered and discharged upward from the air outlet 4, which can increase the separation and dust removal effects of the particle material.

[0023] See also Figure 2A pulse spraying device 15 is provided on one side outer wall of the cyclone material gas separator 1, and the pulse spraying device 15 includes an air storage bag 7 and a pulse valve 5. The air storage bag 7 is fixedly connected to one side outer wall of the cyclone material gas separator 1, and pulse valves 5 are fixedly installed at both ends of the top side of the air storage bag 7;

[0024] By providing a pulse jet loading 12, the dust on the filter cartridge body 12 can be removed by back-blowing with compressed air, and the dust can be shaken off. The dust accumulated on the filter bag body 12 can be periodically pulse-jet-cleaned, so that the purified gas can pass normally, thereby ensuring the operation of the dust removal system.

[0025] See also Figures 1 to 3 The guide cone 10 is fixedly connected to the inner wall of the cyclone gas separator 1, the bottom of the guide cone 10 is a truncated cone that is wide at the top and narrow at the bottom, the guide plate 11 is fixedly connected to the inner wall of the guide cone 10, the filter cartridge body 12 is fixedly connected to the filter cartridge gas separator 2 by bolts, the ash hopper 9 is shaped like a truncated cone that is wide at the top and narrow at the bottom, the bottom of the ash hopper 9 is fixedly connected with a discharge port 14, the surface of the discharge port 14 is fixedly installed with a discharge valve 8, the head 13 is consistent with the size of the top of the cyclone gas separator 1, and is fixedly connected to the top of the cyclone gas separator 1 by bolts, and a level meter 6 is fixedly installed on one side of the outer wall of the cyclone gas separator 1;

[0026] The material level in the silo is detected by the material level meter 6. When the material in the silo reaches the upper limit of the material level, the material level meter 6 feeds back a signal to the release valve, which automatically opens to force the suction of materials to stop (the vacuum pump operates normally). At the same time, an alarm is sounded to remind the operator to unload the materials or troubleshoot the fault. When the pressure and material level return to normal, the release valve is closed to continue suctioning.

[0027] In the utility model, the working principle of the device is as follows:

[0028] The fan generates negative pressure, and the material is mixed with a certain amount of air through the suction nozzle, and then sent to the material-gas separator 1 through the conveying pipe for material-gas separation. When the dust-laden airflow enters the cyclone material-gas separator 1 along the tangential direction of the feed port 3 at a speed of 12 to 25 m / s, it moves downward in a spiral along the gap between the outer cylinder and the filter-type material-gas separator 2, generating inertial centrifugal force. During the rotation process, the space suddenly becomes larger, and the material speed drops rapidly to a level much lower than the material suspension speed, and then it quickly settles and falls. At the same time, the material hits the guide cone 10 and the guide plate 11, and also The dust particles are separated and fall to the bottom of the dust collecting hopper 9, and the heavier dust particles are thrown to the wall by the centrifugal force, and fall into the dust collecting hopper 9 under the downward gravity and the momentum along the wall, and are discharged through the discharge valve 8; some of the materials and dust impact the guide plate 11 and sink after losing kinetic energy, and a small amount of materials rise with the air to the filter cartridge material-gas separator 2, and the clean air after filtration and separation by the filter cartridge body 12 passes through the filter and then flows upward from the air outlet 4 and the air duct into the air inlet of the fan or vacuum pump, and is discharged into the atmosphere after passing through the fan;

[0029] A pulse spraying device (pulse valve 5 and air storage bag 7) is provided on one side of the cyclone gas separator 1. Each filter bag has a spraying air pipe on the top aligned with it. The dust accumulated on the filter cartridge body 12 can be removed by back-blowing with compressed air, so that the filter cartridge body 12 expands rapidly in an instant and shakes off the dust accompanied by the reverse action of the airflow. The shaken-off dust falls into the ash hopper and is discharged through the discharge valve 8, so that the dust accumulated on the filter bag body 12 is periodically pulse-sprayed and cleaned, so that the purified gas can pass normally.

[0030] Compared with the existing technology, this design has the characteristics of reasonable and compact structure, small size, can improve the separation and dust removal effect, easy installation, maintenance and use, can reduce the breakage rate of granular materials, can reduce the use cost and extend its service life. It is particularly suitable for the separation and dust removal of granular materials.
