Description

Technical Field

[0001] This invention belongs to the technical field of solid hazardous waste pretreatment equipment, specifically relating to a device for homogenizing solid particulate materials in a large silo. Background Technology

[0002] With the continuous development of the global economy, the amount of solid waste generated is constantly increasing, especially hazardous solid waste, which poses a serious threat to the environment. Therefore, the disposal of hazardous solid waste is particularly important. The homogenization of different types of hazardous solid waste is a crucial preliminary step in hazardous solid waste treatment, especially in the large-scale and ultra-large-scale hazardous solid waste treatment industry, where batch processing is imperative. Currently, the large silo devices used for homogenization of hazardous solid waste suffer from low equipment utilization and low homogenization levels, severely impacting subsequent processes such as incomplete reactions, leading to waste and the generation of harmful gases that cause environmental pollution. Large silos for homogenization of hazardous solid waste are also large in size (up to 20m in height and 6m in diameter), resulting in a large overall mass of material within the silo. Furthermore, the silo must also function as a mixing and temporary storage unit during the entire mixing process. This makes it difficult for general silo homogenization mechanisms, such as spiral agitators, to meet the requirements for homogenization of hazardous solid waste, rendering them unsuitable for this purpose. Summary of the Invention

[0003] To address the aforementioned problems in the prior art, the present invention provides a device for homogenizing solid particulate materials in large silos.

[0004] The object of this invention is achieved in the following manner:

[0005] A solid particulate material homogenization device for a large silo includes a silo, a material layering conveying module and at least one set of silo homogenization modules inside the silo. The silo homogenization modules divide the silo into multiple mixing spaces. Each silo homogenization module includes a disc with a discharge port at its center. Multiple sets of single-sided baffle spiral feeding assemblies are evenly arranged on the upper surface of the disc. The single-sided baffle spiral feeding assemblies spirally convey the material on the disc to the discharge port at the center of the disc. The drive mechanism of the single-sided baffle spiral feeding assemblies is installed on the silo. A conical tooth ring is provided on the lower surface of the disc. The conical tooth ring meshes with a conical tooth power assembly installed on the silo. The disc rotates under the drive of the conical tooth power assembly and the conical tooth ring. One end of the single-sided baffle of the single-sided baffle spiral feeding assembly is fixed to the silo, and the other end is fixed to a connecting column.

[0006] The material layering conveying module includes at least one connecting column, which is inserted into the material discharge port at the center of the disc. The upper end is threaded to the top of the silo, and the lower end is threaded to the bottom of the silo. At least one conical dispersing frame is fitted on the connecting column. The conical dispersing frame is located above the disc, and the bottom diameter of the conical dispersing frame is larger than the diameter of the material discharge port at the center of the disc. The number of conical dispersing frames is the same as the number of discs.

[0007] At least three sets of limiting mechanisms are evenly arranged around the circumference of the disc. The limiting mechanism includes a limiting plate and a U-shaped block welded to the silo. The U-shaped block is located above the limiting plate, and the limiting mechanism limits the disc axially.

[0008] Three sets of single-sided baffle spiral feeding assemblies are evenly arranged on the upper surface of the disc.

[0009] Each bevel gear ring meshes with three sets of bevel gear power components.

[0010] Four sets of silo homogenization modules are installed inside the silo.

[0011] There are three connecting columns, which are evenly distributed in the material drop hole in the center of the disc.

[0012] A retaining ring is installed on the connecting column to limit the conical dispersion frame.

[0013] The silo has a feed inlet at the top center and a cone-shaped bottom with a discharge outlet at the bottom. The discharge outlet is equipped with a control valve.

[0014] Compared with the prior art, the present invention discloses a solid particulate material homogenization device for a large silo. The material enters the silo from the center of the top of the silo, and enters the homogenization module of the silo through the material layering conveying module for stirring. After multi-stage stirring and homogenization treatment, the material enters the bottom of the silo, and finally is discharged through the bottom control valve of the silo. This process realizes the homogenization process of different types of solid hazardous waste. This process can improve the utilization rate of the equipment, accelerate the homogenization efficiency of the material, and provide a guarantee for the smooth implementation of subsequent processes.

Detailed Implementation

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the implementation of the present invention, not all of it. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] A solid particulate material homogenization device for a large silo includes a silo 100, within which a material layering conveying module 200 and at least one set of silo homogenization modules 300 are arranged. The at least one set of silo homogenization modules 300 divides the silo 100 into multiple mixing spaces. Figure 1 As shown, four sets of silo homogenization modules 300 are installed inside the silo 100, namely a first-level silo homogenization module, a second-level silo homogenization module, a third-level silo homogenization module and a fourth-level silo homogenization module, which divide the silo 100 into four layers of mixing space. After multi-stage stirring and homogenization treatment, the material enters the bottom of the silo and is finally discharged through the bottom control valve of the silo.

[0022] like Figure 4 As shown, the silo homogenization module 300 includes a disc 320 with a material discharge port at the center of the disc 320. Multiple sets of single-sided baffle spiral feeding assemblies 310 are evenly arranged on the upper surface of the disc 320. The single-sided baffle spiral feeding assemblies 310 spirally convey the material on the disc to the material discharge port at the center of the disc.

[0023] Because the material on disk 320 is extremely heavy, at least three sets of limiting mechanisms are evenly arranged around the circumference of disk 320 to improve its supporting stability. For example... Figure 2As shown, the limiting mechanism includes a limiting plate 130 and a U-shaped block 120 welded to the inner wall of the silo 100. The U-shaped block 120 is located above the limiting plate 130. The limiting plate 130 and the U-shaped block 120 cooperate to axially limit the disc 320 of the silo homogenization module 300. The distance between the U-shaped block 120 and the limiting plate 130 is related to the thickness of the disc 320. The U-shaped block 120 is generally welded to the inner wall of the silo 100 about 15cm above the limiting plate 130. When two sets of limiting mechanisms are set circumferentially on the disc 320, they should be at both ends of the disc's diameter. If the material is unevenly distributed, it is easy to cause skewing and unstable support. Therefore, generally, three sets of limiting mechanisms are set axially on the disc 320, which can meet the requirements of the support structure without making the structure too complicated.

[0024] The drive mechanism of the single-sided baffle screw feeder assembly 310 is installed on the silo. About 170cm above the limiting plate 130, there are three protruding bosses evenly distributed around the circumference of the silo. The protruding bosses are outside the silo, and a central hole is opened on the protruding bosses facing the inside of the silo. The drive mechanism of the single-sided baffle screw feeder assembly 310 is fixed on the protruding bosses. The rotating shaft of the drive mechanism passes through the central hole and connects to the conveying screw of the single-sided baffle screw feeder assembly 310. One end of the single-sided baffle 311 of the single-sided baffle screw feeder assembly 310 is connected to the U-shaped block 120, and the other end is connected to the connecting column 220 of the material layering conveying module 200. This enables the single-sided baffle screw feeder assembly 310 to be fed when the disc 320 rotates. The single-sided baffle 311 can block part of the rotation of the material, thereby improving the mixing capacity of the single-sided baffle screw feeder assembly 310.

[0025] Furthermore, three sets of single-sided baffle spiral feeding assemblies 310 are evenly and symmetrically arranged on the upper surface of the disc 320, so that the material falling into the upper surface of the disc 320 can be stirred evenly in time and spirally conveyed to the discharge port in the center of the disc.

[0026] A beveled tooth ring 340 is provided on the lower surface of the disc 320. The beveled tooth ring 340 is fixed to the disc 320 by screws. The beveled tooth ring 340 meshes with the beveled tooth power assembly 330 installed on the silo 100. The beveled tooth power assembly 330 drives the beveled tooth ring 340 to rotate, thereby realizing the rotation of the disc 320. The rotation of the disc 320 drives the material to rotate synchronously. The material is dynamically fed to the single-sided partition screw feeder assembly 310 through rotation.

[0027] The bevel gear power assembly 330 is installed on the silo 100. Specifically, three protruding bosses are evenly distributed around the circumference of the drum 110. The protruding bosses are located outside the silo, about 150cm below the limiting plate 130. A central hole is opened on the protruding bosses facing into the silo. The power source of the bevel gear power assembly 330 is fixed on the protruding bosses. The rotation shaft of the power source passes through the central hole and the gear connecting the bevel gear power assembly 330.

[0028] An even more advanced preferred solution is that each bevel gear ring 340 meshes with three sets of bevel gear power components 330, and the number of bevel gear power components 330 activated can be adjusted in a timely manner according to the weight of the material.

[0029] The material layering conveying module 200 includes at least one connecting column 220, which is inserted into the material discharge port at the center of the disc. The upper end of the connecting column 220 is threaded to the top of the silo 100, and the lower end is threaded to the bottom of the silo 100. At least one conical dispersing frame 210 is fitted onto the connecting column 220. The conical dispersing frame 210 does not move relative to the connecting column 220 and is located above the disc 320. The conical dispersing frame 210 is generally located in the middle of the mixing space, i.e., between the discs of the two sets of silo homogenization modules 300. The bottom diameter of the conical dispersing frame 210 is larger than the diameter of the material discharge port at the center of the disc. The number of conical dispersing frames 210 is the same as the number of discs 320.

[0030] like Figure 3 As shown, four sets of silo homogenization modules 300 are arranged inside the silo, and four conical dispersing frames 210 are correspondingly set on the connecting columns 220. The conical dispersing frames 210 do not move relative to the connecting columns 220. The conical dispersing frames 210 can be fixedly connected to the connecting columns 220, or a retaining spring 320 can be installed on the connecting columns 220 to limit the movement of the conical dispersing frames 210. A further preferred embodiment has three connecting columns 220, evenly distributed in the central material discharge hole of the disc. These three connecting columns can better support the conical dispersing frames 210 and prevent them from tilting during material discharge.

[0031] The silo 100 has a feed inlet at the top center to allow materials to enter and be fed into the silo; the bottom of the silo 100 is conical, and a discharge outlet is set at the bottom of the conical bottom. A control valve 140 is installed at the discharge outlet to allow the mixed materials to be discharged.

[0032] The specific working process of the solid particulate material homogenization device in a large silo is as follows:

[0033] Material enters from the top of silo 100 and falls onto the dispersing rack 210 of the first-layer material stratification conveying module 200. After collision and mixing, it enters the disc 320 of the first-stage silo homogenization module 300. The conical tooth power component 330 drives the conical tooth ring 340 to rotate. The conical tooth ring 340 is fixed to the disc 320 with screws, thereby realizing the rotation of the disc 320. The rotation of the disc 320 drives the material to rotate synchronously. The material is dynamically fed to the single-sided partition screw feeder component 310 through rotation. The single-sided partition 311 blocks part of the material's rotation, thereby improving the mixing capacity of the single-sided partition screw feeder component 310. The material is screwed through the single-sided partition 311 screw feeder component 310 to the discharge port in the center of the disc 320, thus entering the next stage of mixing. The material falls from the discharge port at the center of the disc 320 of the primary silo homogenization module 300 onto the dispersion rack 210 of the secondary material stratification conveying module 200, and then onto the disc 320 of the secondary silo homogenization module 300. This process is repeated until the material falls from the discharge port at the center of the disc 320 of the quaternary silo homogenization module 300 into the bottom of the conical silo. Finally, the final control valve 140 is opened, and the material is discharged out of the silo through the outlet. If the material homogenization standard is still not met after the above four-layer homogenization and mixing process, the material released by the solenoid valve can be sent to the top of the silo for recirculation until the homogenization standard is achieved.

[0034] This invention discloses a solid particulate material homogenization device for a large silo. The material enters the silo from the center of the top and is conveyed through a material layering module to a homogenization module for stirring. After multi-stage stirring and homogenization, the material enters the bottom of the silo and is finally discharged through a control valve at the bottom of the silo. This process achieves the homogenization of different types of solid hazardous waste, which can improve the utilization rate of the equipment, accelerate the homogenization efficiency of the material, and ensure the smooth implementation of subsequent processes.

[0035] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be considered within the scope of protection of the present invention.
