Description

Technical Field

[0001] This utility model relates to the field of solid waste treatment technology, specifically to a mechanical and biological treatment device for urban solid waste. Background Technology

[0002] In order to facilitate mechanical processing and improve the heat recovery capacity of waste, urban solid waste generally needs to be pre-treated during the treatment of municipal solid waste. The existing pre-treatment structure simply uses rotation to crush the solid waste during use. Although such crushing structure is more uniform than hammer crusher, it still requires repeated crushing operations, resulting in relatively low processing efficiency. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a mechanical biological treatment device for urban solid waste. Through the cooperation of the solid waste mechanical treatment frame component and the staggered linkage treatment component, the device achieves staggered crushing by differential rotation of the crushing blades through a single drive structure during use. The circumferential crushing keeps the waste moving inward, increasing the contact probability between the blades and the waste, and greatly improving the efficiency of urban solid waste treatment.

[0004] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: a mechanical-biological treatment device for urban solid waste, comprising:

[0005] A solid waste mechanical treatment frame assembly includes a solid waste treatment frame, a top plate at the top of the solid waste treatment frame, a feed pipe communicating with the solid waste treatment frame, a concave frame fixed to the bottom surface of the solid waste treatment frame, an electric rotating shaft disposed in the concave frame, a cover plate connected to the electric rotating shaft, and a feed port opened on the top surface of the feed pipe.

[0006] An interleaved linkage processing assembly includes a rotary motor disposed on the surface of the top plate, a gear disk connected to the output end of the rotary motor, a first gear meshing with the gear disk, a first rotating shaft connected to the first gear, a second gear meshing with the gear disk, a second rotating shaft connected to the second gear, a third gear meshing with the gear disk, a third rotating shaft connected to the third gear, a long shaft connected to the bottom surface of the first gear, and a crushing blade fixed to the side wall of the long shaft.

[0007] In a preferred embodiment of the urban solid waste mechanical biological treatment device described in this utility model, the diameters of the first gear, the second gear, and the third gear decrease sequentially, and the positions of the second gear and the third gear are provided with a long shaft and a crushing blade of the same structure.

[0008] As a preferred embodiment of the urban solid waste mechanical biological treatment device described in this utility model, the pulverizing blades are provided in a plurality of positions, and the pulverizing blades distributed at three long axis positions are staggered with each other.

[0009] As a preferred embodiment of the urban solid waste mechanical biological treatment device described in this utility model, it further includes an auxiliary feeding assembly, which includes a drive motor disposed at the side end of the feed pipe, a transmission shaft connected to the output end of the drive motor, and an auger plate fixed on the transmission shaft.

[0010] As a preferred embodiment of the urban solid waste mechanical biological treatment device described in this utility model, the auxiliary feeding component further includes a through hole opened on the auger plate and a water outlet opened on the bottom surface of the feeding pipe.

[0011] In a preferred embodiment of the urban solid waste mechanical-biological treatment device described in this utility model, a lifting ring is fixed on the top plate, and the solid waste treatment frame is lifted by the lifting ring.

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] By cooperating with the solid waste mechanical treatment frame components and the staggered linkage treatment components, the differential rotation of the crushing blades can be achieved through a single drive structure during use, resulting in staggered crushing. The circumferential crushing keeps the waste moving inward, increasing the contact probability between the blades and the waste, and greatly improving the efficiency of urban solid waste treatment.

[0014] By setting up auxiliary feeding components, the solid waste feeding is assisted, and the dewatering rate of solid waste is greatly improved. This achieves efficient feeding and efficient dewatering at the same time, further improving the efficiency of solid waste treatment.

[0015] In practical use, solid waste is fed into the solid waste treatment frame through the feed pipe. At this time, the rotary motor drives the gear disk to rotate, and the gear disk drives the first gear, the second gear and the third gear to rotate simultaneously. Since the diameters of the first gear, the second gear and the third gear are different, their rotation speeds are different. At the same time, the rotation speeds of the long shaft and the crushing blade at the corresponding positions are also different, realizing differential alternating rotation crushing. Since the first gear, the second gear and the third gear are distributed around the gear disk, the crushing blade pushes the waste material inward when it rotates, increasing the probability of contact between waste materials and further improving the crushing efficiency.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] This utility model provides a mechanical-biological treatment device for urban solid waste. Through the cooperation of the solid waste mechanical treatment frame component and the staggered linkage treatment component, during use, the differential rotation of the crushing blades can be achieved through a single drive structure to achieve staggered crushing. The circumferential crushing keeps the waste moving inward, increasing the contact probability between the blades and the waste, and greatly improving the efficiency of urban solid waste treatment.

[0027] Figures 1-4 The diagram shown is an overall structural schematic of one embodiment of the mechanical-biological treatment device for urban solid waste according to this utility model. Please refer to [link / reference]. Figure 1-4 The main structure of this embodiment includes: a solid waste mechanical treatment frame assembly and an interleaved linkage treatment assembly.

[0028] The solid waste mechanical treatment frame assembly is used in conjunction with the interleaved linkage treatment assembly. Specifically, the solid waste mechanical treatment frame assembly includes a solid waste treatment frame 11, a top plate 12 at the top of the solid waste treatment frame 11, a feed pipe 13 communicating with the solid waste treatment frame 11, a concave frame 14 fixed to the bottom surface of the solid waste treatment frame 11, an electric rotating shaft 15 disposed in the concave frame 14, a cover plate 16 connected to the electric rotating shaft 15, and a feed inlet 17 opened on the top surface of the feed pipe 13.

[0029] In practical use, the interleaved linkage processing component is installed and used based on the solid waste processing frame 11 and the top plate 12 to achieve efficient solid waste processing, and the electric rotating shaft 15 drives the cover plate 16 to flip so that the crushed waste can be directly poured out.

[0030] The staggered linkage processing assembly is used to achieve high-efficiency crushing of solid waste. Specifically, the staggered linkage processing assembly includes a rotary motor 21 disposed on the surface of the top plate 12, a gear disk 22 connected to the output end of the rotary motor 21, a first gear 24 meshing with the gear disk 22, a first rotating shaft 23 connected to the first gear 24, a second gear 26 meshing with the gear disk 22, a second rotating shaft 25 connected to the second gear 26, a third gear 28 meshing with the gear disk 22, a third rotating shaft 27 connected to the third gear 28, a long shaft 29 connected to the bottom surface of the first gear 24, and a crushing blade 210 fixed to the side wall of the long shaft 29.

[0031] In practical use, solid waste is fed into the solid waste treatment frame 11 through the feed pipe 13. At this time, the rotary motor 21 drives the gear disk 22 to rotate. The gear disk 22 drives the first gear 24, the second gear 26, and the third gear 28 to rotate simultaneously. Since the diameters of the first gear 24, the second gear 26, and the third gear 28 are different, their rotation speeds are different. At the same time, the rotation speeds of the long shaft 29 and the crushing blade 210 at the corresponding positions are also different, realizing differential alternating rotation crushing. Since the first gear 24, the second gear 26, and the third gear 28 are distributed around the gear disk 22, the crushing blade 210 pushes the waste material inward when rotating, increasing the contact probability between waste materials and further improving the crushing efficiency. After crushing, the electric rotating shaft 15 drives the cover plate 16 to flip so that the crushed waste material can be directly poured out.

[0032] Furthermore, by setting up auxiliary feeding components, the solid waste feeding is assisted while the dewatering rate of solid waste is greatly improved, realizing efficient feeding and efficient dewatering at the same time, and further improving the solid waste treatment efficiency.

[0033] During feeding, the drive motor 31 drives the transmission shaft 32 to rotate, and the transmission shaft 32 drives the auger blades 33 to rotate. The auger blades 33 realize the transmission of the waste. During the transmission process, the waste is squeezed, and the wastewater overflows directly through the through hole 34 and is finally discharged through the outlet 35. This reduces the wastewater content in the waste and improves the crushing efficiency.

[0034] Furthermore, a lifting ring 41 is fixed on the top plate 12, and the solid waste treatment frame 11 is lifted by the lifting ring 41.

[0035] In this way, the entire solid waste treatment frame 11 is hoisted for use.

[0036] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
