Technical Field

[0001] The utility model relates to the technical field of sludge carbonization furnaces, in particular to a sludge wall-breaking carbonization furnace with a turnover structure. Background Art

[0002] Sludge is a misplaced resource that contains rich organic matter and nutrients such as nitrogen, phosphorus, and potassium. Sludge carbonization is a sludge treatment technology that uses heating and pressurization to lyse cells in the sludge, releasing water and retaining carbon. Sludge carbonization technology can effectively reduce the moisture content and volume of sludge. At the same time, the product has a high carbon content and high calorific value, which makes it highly valuable.

[0003] Sludge wall-breaking carbonization furnace is used in sludge drying, and existing sludge has also begun to be treated by carbonization. During the treatment process, the front-end treatment is carried out first, and then the treated sludge is dried by a drying drum. The dried sludge is transported to the carbonizer through spiral blades for high-temperature treatment. The high temperature evaporates all the water in the sludge and decomposes the harmful organic matter in the sludge, while retaining the carbon and organic matter in the sludge to the maximum extent. However, the sludge wall-breaking carbonization furnace will dry the sludge into lumps when heated, which is not conducive to the subsequent production of carbonized rods. Utility Model Content

[0004] The purpose of the utility model is to provide a sludge wall-breaking carbonization furnace with a flip structure to solve the problem raised in the above background technology that the existing sludge wall-breaking carbonization furnace will dry the sludge into lumps during heating, which is not conducive to the subsequent production of carbonized rods.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a sludge wall-breaking carbonization furnace with a turnover structure, comprising a support frame, a carbonization cylinder and an exhaust pipe, wherein the carbonization cylinder is mounted on the upper side of the support frame, the top of the carbonization cylinder is connected to the exhaust pipe, one side of the carbonization cylinder is connected to a feed pipe, and the bottom of the carbonization cylinder is provided with a discharge port;

[0006] A driving motor is installed on one side of the carbonizing cylinder, and the output end of the driving motor is connected to the feeding auger through a coupling. The end of the feeding auger away from the driving motor is connected to the rotating cylinder. A reserved groove is provided on the side of the rotating cylinder away from the driving motor, and a material guiding stirring blade is connected to the outside of the rotating cylinder.

[0007] Preferably, a control box is connected to the upper side of the support frame, and one side of the rotating cylinder is rotatably connected to the carbonization cylinder through a bearing seat.

[0008] Preferably, the spiral blade on the outer side of the feeding auger is arranged in the opposite direction to the material guiding and stirring blade, and the outer side of the material guiding and stirring blade is in contact with the inner wall of the carbonization cylinder.

[0009] Preferably, a material guide pipe is connected to the discharge port of the carbonization cylinder, and a crushing box is connected to the bottom of the material guide pipe.

[0010] Preferably, a first crushing roller and a second crushing roller are provided inside the crushing box, one end of the first crushing roller is rotatably connected to the crushing box through a bearing seat, and the other end of the first crushing roller is inserted through a notch inside the crushing box.

[0011] Preferably, both ends of the second crushing roller are inserted into the notch on the adjacent side, one side of the second crushing roller is connected to the output end of the servo motor through a coupling, and one side of the servo motor is connected to the crushing box.

[0012] Preferably, a transmission gear is installed on the side of the first crushing roller and the second crushing roller away from the servo motor, and the two transmission gears are meshed with each other, and a discharge port is provided at the bottom of the crushing box.

[0013] Compared with the existing technology, the beneficial effect of the utility model is that the sludge wall-breaking carbonization furnace with a flipping structure can uniformly heat and dry the sludge by continuously flipping the sludge, and then carbonize it, which can effectively improve the drying efficiency of the sludge, and can crush the carbonized sludge to facilitate the subsequent processing of the carbonized sludge, solving the problem that the existing sludge wall-breaking carbonization furnace will dry the sludge into lumps when heated, which is not conducive to the subsequent production of carbonized rods.

[0014] 1. In order to improve the efficiency of sludge drying, the sludge is introduced into the carbonization cylinder through the feed pipe at the carbonization cylinder, and the drive motor is started. The output end of the drive motor drives the feed auger to rotate through the coupling, guiding the sludge to the reserved groove. After passing through the reserved groove and being introduced into the inner side of the carbonization cylinder, the guide and stirring blades on the outer side of the rotating cylinder will guide the sludge to the discharge port for discharge. The sludge wall-breaking carbonization furnace with a flipping structure can continuously flip the sludge so that the sludge can be evenly heated and dried, and then carbonized, which can effectively improve the sludge drying efficiency.

[0015] 2. The sludge wall-breaking carbonization furnace with a flipping structure is designed to facilitate the subsequent treatment of the carbonized sludge. After the carbonized sludge is discharged from the discharge port at the bottom of the carbonization cylinder, the servo motor installed on one side of the crushing box is started to drive the second crushing roller and the transmission gear to rotate through the coupling. The meshing action between the transmission gears drives the first crushing roller and the second crushing roller to engage with each other, crushing the carbonized sludge, and discharging the crushed sludge from the discharge port. The sludge wall-breaking carbonization furnace with a flipping structure can crush the carbonized sludge, which is convenient for the subsequent processing of the carbonized sludge.
