Description

Technical Field

[0001] This invention relates to the field of solid waste treatment technology, specifically to a non-metallic solid waste treatment device. Background Technology

[0002] Non-metallic solid waste (such as waste plastics, rubber, fiber products, or agricultural and forestry waste) typically requires crushing and volume reduction followed by mixing and modification during processing. Currently, most non-metallic solid waste treatment devices on the market adopt a split structure, meaning the crushing equipment and mixing equipment are independently located at different workstations. In actual operation, the material needs to be crushed in the crushing equipment and then transferred manually or by belt conveyor to a separate mixing tank for reagent addition and mixing.

[0003] This split-type operation process has the following prominent problems: First, the height difference and lateral distance between the crushing and mixing stations easily generate a large amount of dust during material transfer, resulting in a harsh working environment and high material loss. Second, the independent mixing tanks are usually equipped with a single anchor or paddle agitator, which has low mixing efficiency for irregularly shaped and poorly flowing waste particles after crushing, and easily leads to material adhesion and accumulation on the tank wall, resulting in uneven mixing of reagents. Third, the split-type equipment requires independent frame foundations for each unit, which not only occupies a large area, but also, after long-term operation, can easily cause a decrease in the docking accuracy between the crushing outlet and the mixing tank inlet due to vibration, resulting in material leakage. In addition, some existing crushing mechanisms rely solely on a single rotating blade group for cutting, lacking a staggered extrusion structure with side-fixed blades, which is not effective in crushing tough non-metallic waste materials and easily leads to problems such as large particle size differences and uneven particle size. Summary of the Invention

[0004] This invention proposes a non-metallic solid waste treatment device, which solves the problems of uneven mixing and insufficient precision in related technologies.

[0005] The technical solution of the present invention is as follows: A non-metallic solid waste treatment device includes a crushing component and a mixing component; the crushing component includes a crushing support, a crushing motor, and a crushing chamber disposed within the crushing support, the crushing chamber having a solid inlet at the upper part and a solid outlet at the lower part, the crushing motor being drivenly connected to the crushing mechanism within the crushing chamber for crushing non-metallic solid waste; the mixing component includes a mixing support, a mixing box disposed on the mixing support, and a mixing motor, the mixing box having a reagent inlet and a material inlet, the mixing box having a discharge valve at the bottom, the material inlet being connected to the solid outlet, and the mixing motor being drivenly connected to a stirring mechanism within the mixing box for stirring and mixing the crushed waste with the reagent.

[0006] As a preferred embodiment of the present invention, the crushing mechanism in the crushing assembly includes a drive shaft, a driven shaft, a rotating crushing blade, and a side-fixed crushing blade; the drive shaft is connected to the crushing motor via a transmission shaft, the drive shaft and the driven shaft are arranged in parallel, the rotating crushing blade is fixedly installed on the drive shaft and the driven shaft, the side-fixed crushing blade is fixedly installed on the inner wall of the crushing chamber, and the rotating crushing blade and the side-fixed crushing blade are staggered.

[0007] As a preferred embodiment of the present invention, the driving shaft and the driven shaft achieve synchronous rotation in opposite directions through a pair of meshing gears, and both ends of the driving shaft and the driven shaft are mounted on the crushing bracket through connecting bearings.

[0008] As a preferred embodiment of the present invention, the stirring mechanism in the mixing assembly includes a mixing shaft, a straight shaft, a side connecting rod, and an arc-shaped connecting stirring plate; the mixing shaft is drivenly connected to the mixing motor through a coupling, the straight shaft is fixedly installed on the mixing shaft, one end of the side connecting rod is fixedly connected to the straight shaft, and the other end is fixedly connected to the arc-shaped connecting stirring plate, the outer edge of the arc-shaped connecting stirring plate is adapted to the shape of the inner wall of the mixing tank.

[0009] In a preferred embodiment of the present invention, the top of the mixing shaft is mounted on the mixing chamber via an auxiliary bearing.

[0010] In a preferred embodiment of the present invention, the solid outlet of the pulverizing component is located above the mixing component, and the solid outlet is connected to the material inlet of the mixing box through a feed pipe.

[0011] As a preferred embodiment of the present invention, the crushing support and the mixing support are an integrated frame structure.

[0012] In a preferred embodiment of the present invention, the reagent inlet is located at the top or upper side wall of the mixing tank, and the discharge valve is an adjustable valve.

[0013] The working principle and beneficial effects of this invention are as follows:

[0014] 1. This invention, through the design of arc-shaped connecting stirring plates and side connecting rods, uses a mixing motor to drive the mixing shaft to rotate the straight shaft. The side connecting rods transmit power to the arc-shaped connecting stirring plates, causing them to adhere closely to the inner wall of the mixing chamber and perform circumferential scraping and mixing motion. This not only pushes the bottom material upwards but also scrapes away the material and agents adhering to the wall surface in real time, preventing local accumulation dead zones and achieving a high degree of uniformity in the mixing of crushed waste and agents.

[0015] 2. This invention, through the integrated frame structure and auxiliary bearings, welds the crushing support and mixing support into a whole, eliminating the relative displacement caused by vibration in the separate equipment and ensuring the alignment accuracy of the flanges of the solid outlet and the material inlet; at the same time, an auxiliary bearing is added to the top of the mixing shaft to constrain the radial swing of the shaft end and ensure the perpendicularity of the axis when the long shaft rotates, thereby ensuring smooth transmission and reliable sealing of each interface.

[0025] Example

[0026] like Figures 1-5As shown, a non-metallic solid waste treatment device includes a crushing component 1 and a mixing component 2. The crushing component 1 includes a crushing support 11, a crushing motor 14, and a crushing chamber disposed within the crushing support 11. The crushing chamber has a solid inlet 12 at the top and a solid outlet 13 at the bottom. The crushing motor 14 is driven by the crushing mechanism in the crushing chamber for crushing non-metallic solid waste. The mixing component 2 includes a mixing support 21, a mixing box 22 disposed on the mixing support 21, and a mixing motor 23. The mixing box 22 has a reagent inlet 221 and a material inlet 222. The bottom of the mixing box 22 has a discharge valve 223. The material inlet 222 is connected to the solid outlet 13. The mixing motor 23 is driven by the stirring mechanism in the mixing box 22 for stirring and mixing the crushed waste with the reagent.

[0027] A non-metallic solid waste treatment device includes a crushing component 1 and a mixing component 2. The crushing component 1 is supported by a crushing support 11, which forms a crushing chamber. A solid inlet 12 is located at the top of the crushing chamber, and a solid outlet 13 is located at the bottom. A crushing motor 14 is fixed to the crushing support 11, and its output end is connected to the crushing mechanism inside the crushing chamber via a coupling. When the crushing motor 14 starts, it drives the crushing mechanism to rotate, crushing the non-metallic solid waste fed into the solid inlet 12. The crushed material is discharged through the solid outlet 13. The mixing component 2 includes a mixing support 21 and a mixing box 22 fixed to the mixing support 21. The mixing box 22 has a reagent inlet 221 and a material inlet 222 at the top, and a discharge valve 223 installed at the bottom. The material inlet 222 is connected to the solid outlet 13 via a flange interface. The mixing motor 23 is installed above the mixing box 22, and its output shaft extends into the mixing box 22 and is connected to the stirring mechanism for stirring and mixing the crushed material with the agent injected from the agent inlet 221. After the mixing is completed, the material is discharged through the discharge valve 223.

[0028] The crushing mechanism in the crushing assembly 1 includes a drive shaft 142, a driven shaft 146, a rotating crushing blade 145, and a side-fixed crushing blade 147. The drive shaft 142 is connected to the crushing motor 14 via a transmission shaft 141. The drive shaft 142 and the driven shaft 146 are arranged in parallel. The rotating crushing blade 145 is fixedly installed on the drive shaft 142 and the driven shaft 146. The side-fixed crushing blade 147 is fixedly installed on the inner wall of the crushing chamber. The rotating crushing blade 145 and the side-fixed crushing blade 147 are staggered.

[0029] The crushing mechanism specifically includes a drive shaft 142, a driven shaft 146, rotating crushing blades 145, and side-fixed crushing blades 147. The output end of the crushing motor 14 is keyed to one end of the drive shaft 142 via a transmission shaft 141. Both the drive shaft 142 and the driven shaft 146 are horizontally arranged and their axes are parallel to each other. They are mounted on the crushing support 11 via bearing seats. The rotating crushing blades 145 are disc-shaped blades, respectively fitted and welded to the shaft bodies of the drive shaft 142 and the driven shaft 146. The side-fixed crushing blades 147 are elongated fixed blades, fastened to both sides of the inner wall of the crushing chamber by bolts. The rotating crushing blades 145 and the side-fixed crushing blades 147 are staggered in the axial direction, with gaps between them. When the crushing motor 14 drives the drive shaft 142 to rotate, the rotating crushing blades 145 rotate with the shaft, and the material is crushed by shearing and compression between the rotating crushing blades 145 and the side-fixed crushing blades 147.

[0030] The drive shaft 142 and the driven shaft 146 are rotated synchronously in opposite directions through a pair of meshing gears 143. Both ends of the drive shaft 142 and the driven shaft 146 are mounted on the crushing bracket 11 through connecting bearings 144.

[0031] The drive shaft 142 and the driven shaft 146 achieve synchronous rotation in opposite directions via a pair of meshing gears 143. Specifically, a first meshing gear is fixedly installed at one end of the drive shaft 142 after it extends out of the crushing chamber, and a second meshing gear is fixedly installed at the corresponding end of the driven shaft 146. The two gears have the same number of teeth and mesh with each other. The drive shaft 142 rotates under the drive of the crushing motor 14, which drives the driven shaft 146 to rotate in opposite directions at the same speed through the meshing gears 143. This causes the rotating crushing blades 145 on the two shafts to move towards each other, enhancing the shearing and crushing effect. Connecting bearings 144 are fitted at both ends of the drive shaft 142 and both ends of the driven shaft 146. The outer ring of the connecting bearing 144 is press-fitted into the bearing seat hole on the crushing bracket 11, ensuring smooth rotation of the two shafts and bearing radial loads.

[0032] The stirring mechanism in the mixing assembly 2 includes a mixing shaft 231, a straight shaft 234, a side connecting rod 235, and an arc-shaped connecting stirring plate 236. The mixing shaft 231 is connected to the mixing motor 23 via a coupling 232. The straight shaft 234 is fixedly installed on the mixing shaft 231. One end of the side connecting rod 235 is fixedly connected to the straight shaft 234, and the other end is fixedly connected to the arc-shaped connecting stirring plate 236. The outer edge of the arc-shaped connecting stirring plate 236 is adapted to the shape of the inner wall of the mixing box 22.

[0033] The stirring mechanism in mixing assembly 2 specifically includes a mixing shaft 231, a straight shaft 234, a side connecting rod 235, and an arc-shaped connecting stirring plate 236. The output shaft of the mixing motor 23 is coaxially and fixedly connected to the top end of the mixing shaft 231 via a coupling 232. The mixing shaft 231 extends vertically into the mixing chamber 22, and its lower part is connected to the straight shaft 234 via a shoulder and a key. The straight shaft 234 extends horizontally radially along the mixing shaft 231. One end of the side connecting rod 235 is welded and fixed to the end of the straight shaft 234, and the other end is bent upwards or downwards and then welded and fixed to the inner wall of the arc-shaped connecting stirring plate 236. The radius of curvature of the arc-shaped connecting stirring plate 236 matches the arc-shaped profile of the inner wall of the mixing chamber 22, and its outer edge is close to but does not contact the inner wall of the mixing chamber 22. When the mixing motor 23 drives the mixing shaft 231 to rotate, it drives the arc-shaped connecting stirring plate 236 to move circumferentially along the chamber wall, thoroughly mixing the materials and reagents.

[0034] The top of the mixing shaft 231 is mounted on the mixing box 22 via an auxiliary bearing 233.

[0035] An auxiliary bearing 233 is located at the top of the mixing shaft 231. Specifically, a through hole is formed in the center of the top plate of the mixing chamber 22, and a bearing sleeve is pressed into the through hole. The outer ring of the auxiliary bearing 233 is fixed inside the bearing sleeve. The mixing shaft 231 passes through the inner hole of the auxiliary bearing 233 and is interference-fitted with the inner ring. The coupling 232 is located above the auxiliary bearing 233. The auxiliary bearing 233 is a deep groove ball bearing, which bears the radial force when the mixing shaft 231 rotates and ensures the perpendicularity of the axis, preventing the mixing shaft 231 from wobbling due to material resistance. The bottom end of the mixing shaft 231 is suspended inside the mixing chamber 22, without a bottom bearing, and is positioned and supported by the top auxiliary bearing 233 and the motor end cover bearing.

[0036] The solid outlet 13 of the crushing component 1 is located above the mixing component 2, and the solid outlet 13 is connected to the material inlet 222 of the mixing box 22 through the guide pipe.

[0037] The solid outlet 13 of the crushing component 1 is located above the mixing component 2, and the two are connected by a feed pipe. Specifically, the solid outlet 13 is a rectangular or circular discharge port with a connecting flange welded to its opening. The material inlet 222 of the mixing chamber 22 is also equipped with a flange. The feed pipe is a straight metal pipe, with both ends fastened to the flanges of the solid outlet 13 and the material inlet 222 respectively by bolts, and the internal passage of the pipe is unobstructed. The crushed material in the crushing chamber falls from the solid outlet 13 by gravity and enters the interior of the mixing chamber 22 directly along the feed pipe, avoiding exposure of the material to the external environment and reducing dust emission. The angle between the feed pipe and the horizontal plane is greater than the angle of repose of the material to ensure that the material slides smoothly without clogging.

[0038] The crushing support 11 and the mixing support 21 are an integrated frame structure.

[0039] The crushing support 11 and the mixing support 21 form an integrated frame structure. This integrated frame is welded from channel steel or square steel tubing and includes an upper crushing mounting platform and a lower mixing mounting platform. The crushing support 11 is located on the upper layer of the frame and is bolted to the crushing motor 14 and the crushing chamber housing. The mixing support 21 is located on the lower layer of the frame and is used to support the mixing box 22 and the mixing motor 23. The integrated frame structure allows the crushing assembly 1 and the mixing assembly 2 to be stacked vertically, saving floor space and improving the rigidity and vibration resistance of the entire machine. It also prevents the relative displacement caused by the operation vibration of the separate supports from affecting the alignment accuracy of the solid outlet 13 and the material inlet 222.

[0040] The reagent inlet 221 is located at the top or upper side wall of the mixing tank 22, and the discharge valve 223 is an adjustable valve.

[0041] The reagent inlet 221 is located at the top of the mixing tank 22, specifically as a threaded pipe joint on the tank cover, used to connect to the reagent delivery pipeline. The reagent is injected into the mixing tank 22 through this inlet by pumping or gravity flow. The discharge valve 223 is installed at the discharge port at the bottom of the mixing tank 22. It is an adjustable valve, specifically a manually or electrically driven slide gate valve or butterfly valve. The operator changes the valve plate position by rotating the handwheel or electric actuator, thereby controlling the flow cross-section of the discharge port to achieve continuous or intermittent discharge of the mixed material, facilitating adjustment of the discharge speed according to subsequent process requirements. When the device stops working, the discharge valve 223 is completely closed to intercept residual material in the tank.

[0042] Working Principle: During operation, non-metallic solid waste is fed into the solid inlet 12 at the top of the crushing chamber in the crushing assembly 1. The crushing motor 14 drives the drive shaft 142 to rotate via the transmission shaft 141. The meshing gear 143 installed at one end of the drive shaft 142 drives the meshing gear 143 on the driven shaft 146 to rotate synchronously in opposite directions, causing the rotating crushing blades 145 welded to the drive shaft 142 and the driven shaft 146 to move towards each other. The rotating crushing blades 145 and the side-fixed crushing blades 147 fastened to the inner wall of the crushing chamber are arranged axially in a staggered manner. The material is crushed by shearing and compression between the rotating blades and the fixed blades. The crushed material is discharged from the solid outlet 13 at the bottom of the crushing chamber by gravity and falls directly into the material inlet 222 of the mixing box 22 through the guide pipe connected by the flange. The mixing motor 23 drives the mixing shaft 231, which extends vertically into the mixing chamber 22, to rotate via the coupling 232. A straight shaft 234 mounted on the mixing shaft 231 rotates with the mixing shaft 231 and drives the arc-shaped connecting stirring blade 236 to move circumferentially along the inner wall of the mixing chamber 22 via the side connecting rod 235. The reagent is injected through the reagent inlet 221 at the top of the mixing chamber 22 and is thoroughly mixed with the crushed material under the scraping action of the arc-shaped connecting stirring blade 236. During the mixing process, the auxiliary bearing 233 at the top of the mixing shaft 231 bears the radial force and ensures the perpendicularity of the axis. The uniformly mixed material is discharged through the discharge valve 223 at the bottom of the mixing chamber 22. This discharge valve 223 is an adjustable valve, and the discharge speed is controlled by changing the flow cross-section of the discharge port. The crushing support 11 and the mixing support 21 are welded together as an integrated frame structure to ensure the rigidity of the entire machine and the alignment accuracy of each interface.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
