[0022] 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. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 4 As shown, in this embodiment, the prior art has the following problems: The inventors found that the prior art has the following defects: 1. Direct waste residue entering the box is likely to generate dust and pollute the environment; 2. The waste residue has a complex shape and low processing efficiency; 3. The electric heating drying efficiency of the drying box is low and the energy consumption is large; 4. The dried waste residue needs to be manually discharged, which is inefficient;

[0024] Therefore, the inventor provides a device for collecting industrial solid waste, including a pretreatment device, an exhaust gas drying device, and an automatic conveying device. The pretreatment device is arranged after the exhaust gas drying device, and the automatic conveying device is respectively arranged below the pretreatment device and the exhaust gas drying device; the pretreatment device also includes a dust removal device 1, a vibrating screen 2, and a crushing roller device 3. The dust removal device 1 is arranged above the feed port a14 of the vibrating screen 2, and the crushing roller device 3 is arranged behind the vibrating screen 2 and the outlet of the vibrating screen 2 extends into the feed port b16; the exhaust gas drying device 5 also includes a drying box and an induced draft fan 11. The induced draft fan 11 is arranged above the drying box and the inlet of the induced draft fan 11 is connected to the air outlet of the drying box through a pipeline; the automatic conveying device also includes a conveying device 4 and a screw conveyor 6. The conveying device 4 is arranged below the vibrating screen 2 and the crushing roller device 3, and the screw conveyor 6 is arranged below the exhaust gas drying device 5 and the inlet of the screw conveyor 6 is connected to the outlet of the exhaust gas drying device 5 through a pipeline.

[0025] By adopting the above scheme, the waste slag is poured into the vibrating screen 2, and the dust removal device 1 sprays water mist to isolate the dust in the vibrating screen 2 from the external environment, preventing the dust from entering the air and causing pollution; the vibrating screen 2 screens out the coarser waste slag and sends it to the crushing roller device 3 for crushing, and the finer waste slag falls down to the conveying device 4 and is transported to the tail gas drying device 5. The coarser waste slag is sent to the crushing roller device 3, and after being crushed into finer waste slag, it falls down to the conveying device 4, and is transported to the tail gas drying device 5 by the conveying device 4, thereby screening and crushing the waste slag, and processing it into the same specifications, thereby improving the efficiency of waste slag processing; the treated waste slag enters the tail gas drying device 5 along the conveying device 4, and the tail gas drying device 5 uses the residual heat in the tail gas discharged from the cement kiln to dry the waste slag. After the tail gas dries the waste slag, it is pumped to the decomposition furnace by the induced draft fan 11 for continued use, and finally discharged to the desulfurization tower. After the waste slag is dried, it enters the screw conveyor 6 downward, and the screw conveyor 6 transports the treated waste slag to the next process to complete the collection and processing of the waste slag.

[0026] Further, a hopper a15 is provided below the vibrating screen 2 and the outlet of the hopper a15 is above the conveying device 4;

[0027] Further, a hopper b17 is provided below the crushing roller device 3 and the outlet of the hopper b17 is above the conveying device 4;

[0028] Among them, the hopper a15 and the hopper b17 can respectively collect the processed waste residues in the vibrating screen 2 and the crushing roller device 3, and send them to the conveying device 4 below, so as to improve the working efficiency of the device.

[0029] Furthermore, the drying box also includes a box body 7, a material receiving hopper 8, a driving motor 9, and a drying auger 10. The material receiving hopper 8 is arranged on the upper left side of the box body 7, the driving motor 9 is arranged above the box body 7 and the output end is connected to the drying auger 10, and the drying auger 10 is arranged inside the box body 7;

[0030] Furthermore, a soft brush 13 is provided on the receiving hopper 8;

[0031] Furthermore, an exhaust gas pipe 12 is provided at the lower rear side of the box body 7;

[0032] Among them, the receiving hopper 8 receives the waste slag from the conveying device 4, and the soft brush 13 can brush the waste slag on the conveying device 4 into the receiving hopper 8 to prevent the waste slag from sticking to the conveying device 4. The waste slag falls along the receiving hopper 8 to the impeller of the drying auger 10, and the driving motor 9 drives the drying auger 10 to rotate. The waste slag spirally moves downward on the drying auger 10. The front end of the exhaust gas pipe 12 is connected to the cement kiln to transport the exhaust gas to the exhaust gas drying device 5. The exhaust gas sweeps the waste slag in the opposite direction of the rotation direction of the drying auger 10, and the wind speed and waste heat are used to dry the waste slag. Finally, it is extracted by the induced draft fan 11 and sent to the decomposition furnace for secondary utilization, and then discharged to the desulfurization tower for treatment and then discharged. The waste slag is dried by the waste heat of the exhaust gas, which reduces energy consumption and improves efficiency.

[0033] Further, the fan outlet 18 on the induced draft fan 11 is connected to the flue gas inlet of the calciner through a pipeline;

[0034] The tail gas discharged from the fan outlet 18 can enter the decomposition furnace for reuse.

[0035] In summary, the device includes a pretreatment device, an exhaust gas drying device 5, and an automatic conveying device. The dust removal device 1 in the pretreatment device performs dust removal on the waste slag entering the vibrating screen 2 to prevent dust from polluting the environment; the waste slag is screened, and the coarser waste slag is screened out and sent to the crushing roller device 3 for crushing, thereby unifying the waste slag specifications and improving the processing efficiency; the exhaust gas drying device 5 dries the waste slag, utilizes the waste heat of the exhaust gas, reduces energy consumption, and improves efficiency; the automatic conveying device automatically conveys the treated waste slag to improve efficiency.

[0036] The working principle of the utility model is as follows: the industrial solid waste residue to be processed is fed in from the feed port a14, and the dust removal device 1 above the feed port a14 can spray water mist inward to isolate the dust in the vibrating screen 2 from the external environment, and prevent the dust from entering the air and causing pollution; the waste residue is divided into two parts, a finer part and a coarser part, and the finer waste residue falls into the hopper a15 below the vibrating screen 2, and falls from the hopper a15 to the conveying device 4, and is sent to the tail gas drying device 5; the coarser waste residue is fed into the feed port b16 by the vibrating screen 2, and after being crushed into finer waste residue, falls into the hopper b17 below the crushing roller device 3, and falls from the hopper b17 to the conveying device 4, and is sent to the tail gas drying device 5. After the waste residue is screened and crushed, the waste residue specifications are unified, and the processing efficiency of the device is improved;

[0037] After the waste residue is screened and crushed, it is transported to the tail gas drying device 5 by the conveying device 4 and falls into the receiving hopper 8. Part of the waste residue stuck to the conveying device 4 is scraped off by the soft brush 13 on the receiving hopper 8 and falls into the receiving hopper 8. Then, the waste residue falls along the receiving hopper 8 onto the impeller of the drying auger 10 in the box body 7. The driving motor 9 drives the drying auger 10 to rotate downward, and the waste residue on the impeller is rotated and transported from top to bottom. At the same time, the tail gas pipeline 12 on the box body 7 transports the tail gas discharged from the cement kiln to the box body 7, and the dry waste residue is purged from bottom to top in the opposite direction of the movement of the drying auger 10. The tail gas after the waste residue is dried is extracted by the induced draft fan 11 out of the fan outlet 18 and sent to the decomposition furnace for reuse, and then discharged to the desulfurization tower for treatment and discharge. Under the action of the induced draft fan 11, the pressure in the box body 7 is less than the atmospheric pressure, so the tail gas will not escape from other openings. The tail gas drying device 5 dries the waste residue, utilizes the waste heat of the tail gas, reduces energy consumption, and improves efficiency.

[0038] After drying, the waste residue is discharged downward into the screw conveyor 6, and the screw conveyor 6 conveys the treated waste residue to the conveyor outlet to enter the next process, thereby completing the collection and treatment of industrial solid waste residue.
