Description

Technical Field

[0001] This utility model relates to the technical field of coal processing equipment, and in particular to a crushing equipment for coke oven coal particles. Background Technology

[0002] In the coal processing and coking production sector, the crushing of coke oven coal is a crucial step determining the efficiency of subsequent processes. Currently, the industry primarily relies on jaw crushers and traditional pulverizers for crushing coke oven coal, but both suffer from significant technical bottlenecks in practical applications.

[0003] Jaw crushers, as a typical representative of coarse crushing equipment, crush materials through the reciprocating compression of the moving jaw and the fixed jaw. However, when applied to coke oven coal, they reveal multiple defects: First, the single compression crushing method cannot achieve sufficient fineness of coal particles, often requiring multiple subsequent crushing operations, resulting in energy waste; second, the open crushing chamber lacks an effective anti-splash structure, leading to prominent coal dust emission problems and potential safety hazards.

[0004] Traditional crushers (such as hammer mills and roller mills) focus on medium and fine crushing operations, but they also have inherent shortcomings in coke oven coal processing: their crushing components (such as hammers and rollers) mostly adopt a unidirectional rotation design, which has limited effect on dispersing the coal after preliminary crushing and easily leads to uneven particle size; the screening system relies on static screen plates and lacks a synchronous cleaning mechanism, resulting in frequent problems of coal particle accumulation and blockage, leading to high equipment downtime for maintenance and affecting production continuity.

[0005] The technical shortcomings of the two types of equipment have a cumulative effect in the coke oven coal processing scenario: the incomplete coarse crushing of the jaw crusher leads to a surge in the load of the pulverizer, while the low screening efficiency of the pulverizer has a backlash on the front-end crushing process, forming a vicious cycle of "crushing-screening".

[0006] Therefore, there is an urgent need for a new type of equipment that combines the initial compression advantages of jaw crushers with the high-efficiency refining characteristics of pulverizers, and integrates screening, cleaning, and safety protection functions to solve the above problems.

[0036] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0037] Reference Figure 1-10 The equipment for crushing coke oven coal particles includes a crushing box 1, a feeding shell 11, a screen plate 13, a cleaning frame 23, a rotating plate 3, a crushing plate 31, and two baffles 12.

[0038] The feed guide shell 11 is fixedly installed on the top of the crushing box 1 and connected to the crushing box 1. The bottom of both sides of the crushing box 1 is provided with a discharge port. The screen plate 13 is fixedly installed on the inner walls of both sides of the crushing box 1. Two lower rotating shafts 2 are rotatably installed on the inner wall of the crushing box 1 and are arranged in parallel with each other. Multiple crushing rods 201 are radially fixedly installed on each of the two lower rotating shafts 2. The multiple crushing rods 201 on the two lower rotating shafts 2 are arranged in an alternating manner. A motor 22 is fixedly installed on one side of the crushing box 1. The output shaft of the motor 22 is axially fixedly connected to one of the lower rotating shafts 2, which can crush the coke oven coal falling into the movement area of ​​the crushing rods 201. The ends of the two lower rotating shafts 2 away from the motor 22 extend to the outside of the crushing box 1 and are respectively fixedly fitted with gears 21. The two gears 21 mesh with each other, which can make the two lower rotating shafts 2 rotate in opposite directions, thereby improving the crushing efficiency of the crushing rods 201 on the coke oven coal.

[0039] Two slotted openings are provided on the inner walls of both the front and rear sides of the crushing box 1. The cleaning frame 23 is slidably installed in the four slotted openings and makes movable contact with the top side of the screen plate 13. The same support shaft 301 is rotatably installed on the inner walls of both the front and rear sides of the crushing box 1. The rotating plate 3 is radially fixedly installed on the support shaft 301. The crushing plate 31 is U-shaped and fixedly installed on the rotating plate 3. The outer side of the crushing plate 31 is provided with multiple protrusions. Two stops 12 are fixedly installed on the inner walls of both sides of the crushing box 1 and are arranged symmetrically. The two stops 12 are inclined on the side that is close to each other, and the rotating plate 3 is located between the two stops 12. The front and rear ends of the support shaft 301 extend to the outside of the crushing box 1 and are respectively fixedly fitted with gear 2 302. Two toothed plates 303 are fixedly installed on the cleaning frame 23 and are arranged in parallel with each other. The two toothed plates 303 mesh with the corresponding gear 2 302 respectively. When the rotating plate 3 swings, it can control the cleaning frame 23 to move back and forth along the top side of the screen plate 13, thereby avoiding the coke oven coal from clogging the screen plate 13.

[0040] The rotating plate 3 has a through guide opening. Turntables 32 are rotatably installed on the inner walls of the front and rear sides of the crushing box 1. The two turntables 32 are coaxially arranged. The same guide shaft 33 with the through guide opening is fixedly installed on the side of the two turntables 32 that are close to each other. A second motor 34 is fixedly installed on the front side of the crushing box 1. The output shaft of the second motor 34 extends into the crushing box 1 and is fixedly connected to the turntable 32 on the front side. It can control the rotating plate 3 to swing back and forth based on the support shaft 301 as the center, so that it can perform preliminary crushing operation on large pieces of coke oven coal with the cooperation of the inclined surfaces of the side blocks 12.

[0041] Two parallel upper rotating shafts 41 are rotatably mounted on the inner walls of the front and rear sides of the feed housing 11. Rotating rollers 4 are fixedly mounted on each of the two upper rotating shafts 41, and multiple baffles 401 are fixedly mounted on each of the two rotating rollers 4. The multiple baffles 401 on the two rotating rollers 4 are staggered. When feeding material into the crushing box 1, the rotating rollers 4 rotate under the weight of the coke oven coal and the cooperation of the baffles 401. This can prevent material from splashing when the crushing plate 31 is crushing. The front ends of the two upper rotating shafts 41 extend to the front side of the feed housing 11 and are respectively fixedly fitted with gears 42. The two gears 42 mesh with each other, which can keep the two mounted rollers rotating synchronously in opposite directions. This ensures that the multiple baffles 401 can always maintain a staggered state when moving, thereby effectively intercepting the splashed material and preventing it from splashing and injuring people.

[0042] A rotating pin is rotatably mounted on the front side of the feed guide housing 11. A limiting plate 43 is radially fixedly mounted on the rotating pin. The end of the limiting plate 43 away from the rotating pin is toothed and is movably engaged with the tooth position of one of the gears 42. This can prevent the installation roller from reversing when adding coke oven coal into the feed guide housing 11.

[0043] In this embodiment, in order to discharge the coke oven coal after being screened by the sieve plate 13 into the crushing box 1, a guide plate with a bidirectional inclined top and adapted to the two discharge ports is fixedly installed on the bottom inner wall of the crushing box 1.

[0044] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0045] Working principle: When in use, first connect the power supply and start motor 1 22 and motor 2 34. Coke oven coal is fed into the top of the feed housing 11. Under its own weight, the material slides down the inner wall of the feed housing 11 and controls the rotating roller 4, baffle 401 and gear 3 42 to start operating. The staggered baffle 401 drives the rotating roller 4 to rotate under the push of the material and makes the material enter the crushing box 1. Motor 2 34 makes the rotating plate 3 swing left and right based on the support shaft 301 through the cooperation of the turntable 32, the guide shaft 33 and the guide port. This causes the crushing plate 31 on the rotating plate 3 to move accordingly. With the cooperation of the two baffles 12 that are inclined on the two sides that are close to each other, the large pieces of coal are initially crushed.

[0046] After initial crushing, the material falls downward into the working area of ​​the crushing rod 201. The motor 22 controls multiple crushing rods 201 to perform crushing operations through the cooperation of the lower rotating shaft 2 and gear 21, and performs real-time screening under the action of the screen plate 13. While the rotating plate 3 swings back and forth, the cleaning frame 23 can be controlled by the cooperation of gear 2 302 and toothed plate 303 to perform reciprocating cleaning operations on the screen plate 13. This reciprocating motion can clean the screen plate 13 in a timely manner, ensuring that the screening process is unobstructed and improving the working efficiency of the equipment.

[0047] After being screened by the sieve plate 13, the material continues to fall and is discharged from the crushing box 1 through two outlets under the action of the guide plate set in a bidirectional inclined shape at the top.

[0048] The coke oven coal particle crushing equipment provided by this utility model has been described in detail above. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
