Technical Field

[0001] The utility model relates to the technical field of sludge incineration, in particular to a drying sludge incinerator with high utilization rate. Background Art

[0002] Sludge incineration treatment technology needs to be carried out at very high temperatures, and the organic matter in the sludge is burned in an oxygen-sufficient environment to be converted into gases such as nitrogen dioxide, carbon dioxide, and water vapor. The incineration products are mainly flue gas and ash.

[0003] After searching the Chinese patent with the announcement number CN219264301U, the patent proposes a device for sludge incineration, including a bottom plate, a burning box fixedly installed on the top of the bottom plate, and a vertical plate fixedly installed on the top of the bottom plate, and the vertical plate is located on one side of the burning box. The patent can be incinerated by putting the dehydrated and thermally dried sludge mixed with combustion-supporting materials into the burning box, and then pouring some sludge to be incinerated into the feeding ring, stirring and conveying it by the auger, and the smoke generated by the incinerator will enter the feeding ring through the exhaust pipe, and the internal sludge will be dried again to reduce the moisture that may still exist after the thermal drying treatment, so that it can be dried more thoroughly, and reducing the moisture can reduce the incineration time, and then the smoke in the feeding ring is sucked in by the suction purification structure, purified and discharged, realizing the secondary utilization of the heat of the smoke generated by the incineration, thereby avoiding the waste of thermal energy.

[0004] Based on the above search and combined with the prior art, we found that:

[0005] The existing sludge incineration device adopts the method of directly feeding the feed port. Due to the different shapes and sizes of dry sludge, direct feeding may cause the feed port to be blocked. The dry sludge blocking the feed port needs to be taken out manually before the feeding operation can continue, which reduces the working efficiency of the device and has limitations. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes a dried sludge incinerator with high utilization rate. The utility model has a fragmentation component. When the dried sludge enters the conveying bin, the rotating hollow auger rod drives the fragmentation knife to rotate. The rotation of the fragmentation knife can fragment the dried sludge to facilitate feeding. After the dried sludge is fragmented, it is easy to incinerate fully, which solves the problem that the feed port is blocked due to direct feeding, and the feed port needs to be manually cleaned before continuing the operation, resulting in reduced work efficiency.

[0007] The technical solution to achieve the purpose of the utility model is: a high-utilization dried sludge incinerator, including a conveying bin, a fragmentation assembly is arranged inside the conveying bin, the fragmentation assembly includes a hollow auger rod that movably penetrates the top of the conveying bin, and a plurality of fragmentation knives are fixedly connected to the outer peripheral wall of the hollow auger rod, and also includes;

[0008] A spreading assembly, which is used for evenly spreading the dried sludge, and comprises a spreading roller fixedly connected to the bottom of the hollow auger rod;

[0009] The heating component includes a heat preservation bin fixedly connected to one side of the conveying bin, the bottom of the heat preservation bin is fixedly connected to an air supply pipe 2, and the top of the air supply pipe 2 is detachably and fixedly connected to a filter screen.

[0014] Compared with the prior art, the present invention has the following significant advantages:

[0015] First, the utility model provides a fragmentation component. When the dried sludge enters the conveying bin from the feed bin, the rotating hollow auger rod drives the fragmentation knife to rotate, so as to fragment the dried sludge. At the same time, the fragmented dried sludge is more conducive to incineration, which solves the problem that the existing device adopts the method of directly feeding the feed port. Due to the different shapes and sizes of the dry sludge, direct feeding may cause the feed port to be blocked. The dry sludge blocking the feed port needs to be taken out manually before the feeding operation can continue, resulting in reduced working efficiency of the device.

[0016] Second, the utility model provides a spreading assembly, and the dried sludge after being conveyed and processed by the hollow auger rod and the fragmentation knife falls onto the spreading roller.
