Technical Field
[0001] This utility model belongs to the field of separation and collection devices, and specifically relates to a self-vibrating separation and collection device. Background Technology
[0002] In the process of producing pulverized coal, raw coal typically requires screening and separation using vibrating screens. However, existing vibrating screens have the following drawbacks in pulverizing coal: the raw coal used in the pulverizing area contains lightweight residues such as woven belts, plastic films, and straw mats. During the raw coal grinding and pulverizing process, these lightweight residues are separated from the pulverized coal by the vibrating screen. Most of the pulverized coal enters the injection tank and is injected into the blast furnace, while the remaining debris and pulverized coal are discharged from the waste discharge pipe. Due to the lack of a collection device, temporary cloth bags are used to collect the debris, which is then transported away by handcart, making operation inconvenient and increasing workload. The residues and pulverized coal ejected from the waste discharge pipe spill out in all directions, polluting the environment, causing a smoky and polluted work site, obstructing visibility, and increasing the risk of accidents for employees during equipment maintenance and inspection. This area is an explosive zone, where coal dust can easily cause explosions, posing a significant risk. Each vibrating screen discharges a large amount of coal dust and debris daily, which is usually disposed of haphazardly, resulting in resource waste and increased production costs. The debris separated by screening is covered with a large amount of coal dust, and each time the debris is recovered, coal dust is lost and the surrounding environment is polluted. Coal dust needs to be recovered at least twice a day and the entire platform needs to be cleaned, which greatly increases the labor intensity of the staff.
[0003] In view of this, in order to solve the above problems, this utility model proposes a self-vibrating separation and collection device that realizes centralized collection and secondary effective separation of debris and coal powder, so as to improve the coal powder recycling rate and eliminate resource waste; at the same time, by constructing a closed separation, it avoids coal powder overflow and pollution of the environment and eliminates safety hazards in explosive areas; in addition, through the automated separation structure design, it prevents debris and coal powder from back-blowing and clogging the vibrating screen, reduces the labor intensity of the staff, and ultimately achieves cost reduction and efficiency improvement.

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] See Figure 1-4A self-vibrating separation and collection device includes a separation box 1. Two mounting rings 2 are spaced apart and connected to the upper end of the separation box 1. The mounting rings 2 are respectively set on both sides of the top surface of the separation box 1. A breathable dust collection bag 3 is fixedly connected to each of the two mounting rings 2. The upper end of one breathable dust collection bag 3 is connected to the discharge pipe 4 of the vibrating screen, and the top of the other breathable dust collection bag 3 is sealed. The separation box 1 has an openable and closable door 5 on the side away from the discharge pipe 4. A dust collection and extraction pipe 6 is connected to the side of the separation box 1 opposite to the door 5. The dust extraction pipe 6 is connected to the dust collector. The middle part of the separation box 1 is connected to the separation screen 7 through an elastic support structure. Two vibrating rods 8 are fixed to the upper end of the separation screen 7. The upper ends of the two vibrating rods 8 pass through a breathable dust removal bag 3 and are fixed to the vibrating screen discharge pipe 4. A funnel 9 is provided on the side wall of the separation box 1 directly below the separation screen 7. A coal powder recovery bin 10 is provided directly below the funnel 9. A partition plate 11 is fixed to the lower part of the funnel 9 near the box door 5. A debris collection box 12 is provided on the side of the partition plate 11 away from the coal powder recovery bin 10.
[0020] A debris backflush isolation net 13 is fixedly connected to the side wall of the separation box 1 directly above the debris collection box 12. The debris backflush isolation net 13 is inclined toward the coal powder recovery bin 10, and the lower end of the debris backflush isolation net 13 is located below the separation screen 7. The debris backflush isolation net 13 is used to prevent debris and coal powder from backflushing and clogging the vibrating screen when the residual gas of the injection tank backflushes.
[0021] The preferred separation screen 7 is inclinedly arranged in the middle of the separation box 1, with its bottom end facing the debris collection box 12. This can make full use of the principle of inertia to achieve efficient material conveying, separation and collection.
[0022] The preferred elastic support structure includes springs 14 and support blocks 15. Multiple support blocks 15 are spaced apart on the two side walls of the middle part of the separation box 1. Springs 14 are vertically arranged on the multiple support blocks 15. The separation screen 7 is inclinedly arranged on the upper end of the multiple springs 14. The mechanical vibration of the vibrating screen during operation can drive the springs 14 to vibrate synchronously, thereby realizing the automatic separation of impurities and coal powder. The two mounting rings 2 and the vibrating screen discharge pipe 4 are preferably provided with dust bag fixing rings 16 on their outer sides. The air-permeable dust bag 3 can be removed and cleaned by removing the dust bag fixing rings 16.
[0023] A rain canopy 17 is provided on the outer side of the ventilated dust removal bag 3 on the side opposite to the vibrating screen discharge pipe 4.
[0024] Multiple insertion tubes 18 are symmetrically arranged on the outer side of the ventilated dust removal bag 3 on the side opposite to the vibrating screen discharge pipe 4. Insertion brackets 19 are provided inside the insertion tubes 18, and the canopy 17 is fixed on the top surface of the insertion brackets 19.
[0025] The preferred debris collection box 12 has inclined guide plates 20 on both sides of its top surface, which are connected to the side wall of the separation box 1. The guide plates 20 facilitate the debris to enter the debris collection box 12 more quickly.
[0026] Preferably, a tension spring 21 is vertically connected to the lower surface of the middle part of the separation screen 7 near one end of the debris collection box 12. The free end of the tension spring 21 is connected to the connecting plate on the upper side of the debris collection box 12. The tension spring 21 is designed to protect the separation screen 7 from damage caused by excessive vibration.
[0027] The working principle of this utility model is as follows: When debris and coal dust are discharged from the vibrating screen discharge pipe 4 through the breathable dust removal bag 3 into the separation box 1, the mechanical vibration of the vibrating screen drives the separation screen 7 to vibrate synchronously, thereby realizing the automatic separation of debris and coal dust. The coal dust is separated from the separation screen 7 and falls downward through the funnel 9 into the coal dust recovery bin 10. The debris falls from the bottom of the separation screen 7 into the debris back-blowing isolation net 13 and enters the debris collection box 12 through the guide plate 20. The debris back-blowing isolation net 13 is used to prevent debris and coal dust from back-blowing when the residual gas of the injection tank is back-blown. The clogging vibrating screen is blown out. When the coal powder recovery bin 10 is recovered to a certain extent, the dust collector is activated, and the coal powder is drawn out of the coal powder recovery bin 10 through the dust removal pipe 6, which prevents the waste of coal powder resources, avoids coal powder overflow and pollution of the environment, and eliminates safety hazards in the explosion-prone area. When the debris collection box 12 is full, the box door 5 is opened and the debris is taken out and emptied. This process does not require additional current energy consumption, effectively reducing operating costs and achieving the goal of cost reduction and efficiency improvement. At the same time, debris and unqualified particles automatically fall into the separation box 1 for easy centralized removal.
