Description

Technical Field

[0001] The present application relates to the technical field of drying tank equipment, and in particular to a cyclone drying tank for treating garbage concentrate. Background Art

[0002] At present, garbage concentrate is the residual liquid intercepted by reverse osmosis membrane or nanofiltration membrane after biodegradation of garbage leachate, which is a key problem that must be solved in the current landfill treatment. Previously, garbage concentrates in conventional landfills in China were treated by reinjection, but these concentrates contained high levels of harmful substances such as ammonia nitrogen and nitrate nitrogen. In long-term internal circulation, impurities such as COD and salt will gradually accumulate, inhibit biological activity, reduce the degradation efficiency of microorganisms, and greatly reduce the biodegradability of leachate, affecting the stability of the system. Therefore, it is necessary to continue to study the treatment of garbage concentrate, and the development and research of related technologies is also a hot spot in leachate treatment technology.

[0003] In the relevant technologies, the disposal methods of garbage concentrate can be divided into three categories: the first is transfer treatment, that is, transferring the garbage concentrate, including external transportation and re-injection treatment; the second is further reduction treatment, that is, reducing the absolute content of garbage concentrate by physical and chemical means, and the treatment technologies include reverse osmosis, nanofiltration, evaporation, etc.; the third is harmless treatment, and the treatment technologies include electrocoagulation, precipitation, advanced oxidation and incineration. Among them, evaporation treatment refers to the process in which a part of the components in the garbage concentrate evaporates under certain pressure and temperature conditions. The evaporation treatment has a significant reduction effect and can reduce the volume of the original garbage concentrate to 2~10%.

[0004] The evaporation treatment of garbage concentrate uses a sludge cyclone drying tank. The steam outlet of the sludge cyclone drying tank in the related technology is directly connected to a straight pipe, and a 90° elbow is connected to the side of the steam outlet facing the inside of the tank body. The main function is to prevent liquid from splashing into the outlet pipe and affecting the steam condenser at the rear. However, the setting of the 90° elbow seriously affects the circulation of steam and aggravates the steam saturation in the tank, which not only slows down the evaporation rate of the steam in the tank, but also easily causes damage to the tank body due to excessive pressure in the tank.

[0025] The structure of the fastening assembly and the driving mechanism is described in detail below:

[0026] Specifically, refer to Figure 2 In this embodiment, the fastening assembly includes a fastening screw 33 and a fastening knob cover 34. One end of the fastening screw 33 is fixedly connected to the end of the rotating shaft 31 away from the carrier 3, the diameter of the fastening screw 33 is smaller than the diameter of the rotating shaft 31, and a fastening hole is provided in the middle of the exhaust fan blade 32, the fastening hole and the fastening screw 33 cooperate with each other, so that the exhaust fan blade 32 is inserted into the fastening screw 33 through the fastening hole; the fastening knob cover 34 is threadedly connected to the fastening screw 33, and by rotating the fastening knob cover 34, the fastening knob cover 34 is pressed against the exhaust fan blade 32, so that the exhaust fan blade 32 is firmly installed on the rotating shaft 31.

The provision of the protective pattern can increase friction, thereby making it easier to rotate the fastening knob cover 34; at the same time, it can also effectively prevent slipping during rotation.

[0028] In addition, refer to Figure 1 and Figure 2 In this embodiment, the driving mechanism includes a driving member, a driving gear 41, a driven gear 35 and a linkage assembly.

[0029] Specifically, in this embodiment, the linkage assembly includes a linkage shaft 22, a first linkage gear 23, and a second linkage gear 24. The linkage shaft 22 is rotatably mounted on the side wall of the expansion opening 2, one end of the linkage shaft 22 extends into the interior of the expansion opening 2, and the other end extends out of the expansion opening 2, and the linkage shaft 22 and the rotating shaft 31 are perpendicular to each other; the first linkage gear 23 is fixedly mounted on one end of the linkage shaft 22 away from the rotating shaft 31, and the first linkage gear 23 is meshed with the driving gear 41; the second linkage gear 24 is fixedly mounted on one end of the linkage shaft 22 away from the first linkage gear 23, and the second linkage gear 24 is meshed with the driven gear 35.

[0030] When the drive motor 4 is started, the output end of the drive motor 4 drives the driving gear 41 to rotate, the driving gear 41 drives the first linkage gear 23 to rotate, the first linkage gear 23 drives the linkage shaft 22 to rotate, and the linkage shaft 22 drives the second linkage gear 24, so that the second linkage gear 24 drives the driven gear 35 to rotate, and then the rotating shaft 31 drives the exhaust fan blades 32 to rotate automatically, so as to discharge the steam in the drying tank body 1.

[0031] In addition, refer to Figure 2 and Figure 3 In this embodiment, a filtering mechanism that cooperates with the expansion port 2 is also provided in the drying tank body 1, and the filtering mechanism is located at one end of the expansion port 2 away from the exhaust pipe 21 to pre-filter the steam discharged into the expansion port 2.

[0032] Specifically, the filtering mechanism includes a bearing seat 5, a filtering layer structure 52, a cover plate 53 and a stopper assembly. The bearing seat 5 is installed on the inner top of the drying tank body 1, the bearing seat 5 is located at the end of the expansion port 2 away from the exhaust pipe 21, and a bearing groove 51 is provided on one side of the bearing seat 5 close to the drying tank body 1, and a mounting hole 11 is provided on one side wall of the drying tank body 1, and the mounting hole 11 corresponds to and communicates with the bearing groove 51.

[0038] Better, refer to Figure 3 In this embodiment, a sealing film 14 is also installed on the hole wall of the mounting hole 11. When the cover plate 53 is pressed against by the limit block 13, one side of the cover plate 53 and the sealing film 14 are pressed against each other, thereby increasing the tightness between the cover plate 53 and the drying tank body 1, thereby preventing steam leakage.

[0039] The implementation principle of a cyclone drying tank for treating garbage concentrate in an embodiment of the present application is as follows: when it is necessary to discharge the steam in the drying tank body 1, the drive motor 4 is started, and the output end of the drive motor 4 drives the driving gear 41 to rotate, and the driving gear 41 drives the first linkage gear 23 to rotate, and the first linkage gear 23 drives the linkage shaft 22 to rotate, and the linkage shaft 22 drives the second linkage gear 24, so that the second linkage gear 24 drives the driven gear 35 to rotate, and then the rotating shaft 31 drives the exhaust fan blades 32 to rotate automatically, so as to absorb and discharge the steam in the drying tank body 1.

[0040] The exhausted steam first enters the supporting groove 51 from the connecting hole 54 located at the bottom, and then passes through the filter layer structure 52 to effectively filter and adsorb the steam. The filtered steam then enters the expansion port 2 from the connecting hole 54 located at the top, and is finally discharged from the exhaust pipe 21, thereby completing the process of exhausting the steam in the drying tank body 1.
