Description
Technical Field
[0001] This utility model relates to the field of protective dust collection technology in coal pulverizing, and in particular to a protective dust collection device for coal pulverizing. Background Technology
[0002] In the field of coal processing and testing, coal pulverization is a key process. With the increasing demand for coal quality testing and refined processing of coal products in industrial production, the frequency and scale of coal pulverization operations are increasing day by day. During the pulverization process, the coal powder formed after the coal particles are ground is very easy to fly and spread, resulting in the working environment being filled with a lot of dust.
[0003] Traditional coal pulverizing equipment typically focuses on the coal grinding and crushing mechanism in terms of mechanical structure and technical principles. It generally uses simple grinding mechanical devices, such as a combination of a fixed grinding disc and a rotating grinding disc driven by an electric motor. The relative motion of the two discs is used to crush and pulverize the coal. In terms of dust control, it mostly relies on natural ventilation or a simple exhaust system. By setting up ventilation openings above the working area, some of the raised coal dust is discharged outdoors or collected in a simple dust collection bag by means of natural air flow or airflow generated by a small fan.
[0004] However, this traditional method has serious drawbacks. Due to the lack of effective dust control measures, especially in terms of explosion prevention and efficient dust collection, coal dust is diffused in the air during coal pulverization. Once it encounters a source of ignition or high temperature, it can easily cause an explosion, posing a serious threat to the lives of operators. At the same time, simple ventilation and dust collection methods cannot completely remove coal dust from the work area. A large amount of coal dust residue not only pollutes the working environment, but also affects the normal operation of equipment, reduces production efficiency, and increases equipment maintenance costs in the long run. Therefore, a protective dust collection device for coal pulverization is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides a protective dust collection device for coal pulverizing, which aims to improve the problems in the traditional coal pulverizing process in the prior art, such as coal powder explosion prevention, efficient dust collection, tool placement, convenient cleaning and coal powder collection management, and improve operational safety and work efficiency.

[0013] As a further description of the above technical solution:

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a protective dust collection device for coal pulverizing, comprising a body 1, the body 1 being made of sturdy metal or alloy material, capable of withstanding the pressure of high-frequency operation and dust accumulation, a universal wheel 2 being provided at the bottom of the body 1, the flexibility of the universal wheel 2 allowing the entire device to move easily within the working area, a protective plate 3 being fixedly connected to the top of the body 1, and a dust collection component being provided inside the body 1, the dust collection component being used to efficiently adsorb and collect coal dust generated during the coal pulverizing process, avoiding dust from causing environmental pollution and potential safety hazards;
[0033] The dust collection assembly includes a support block 5, which is fixedly connected to the top of the body 1 to support other components and provide a certain degree of stability. The body 1 has an adsorption port 4 inside, which is used to draw in coal dust from the coal pulverizing process. An adsorption tank 6 is fixedly connected to the top of the support block 5 to collect the dust. The input end of the adsorption tank 6 is fixedly connected to the inside of the adsorption port 4. The body 1 also has multiple adsorption ports 7 inside, which are used to guide dust into the collection assembly. The adsorption ports 7 are wavy to change the airflow direction, enhance the dust collection effect, and more efficiently adsorb the flying coal dust generated during coal pulverization, reducing dust residue. An explosion-proof lighting lamp 8 is fixedly connected inside the body 1, providing illumination for operators. The body 1 also has a pulverizing operation assembly inside, which supports coal pulverizing related operations, providing a convenient and orderly operating space for coal grinding, sample preparation, and table cleaning.
[0034] Specifically, during the coal pulverization process, when coal powder is scattered and blown away due to grinding and other operations, potentially causing environmental pollution and safety hazards, a stable airflow channel is formed inside the device using the negative pressure principle generated by the operation of the fan. This effectively guides the coal powder into the adsorption port 4. Under the action of the airflow, the coal powder is adsorbed and transferred through the adsorption port 4 to the adsorption tank 6 for temporary storage. The main function of the adsorption tank 6 is to collect the coal powder, preventing it from causing pollution or safety hazards to the environment and operators during operation. At the same time, the adsorption port 7 also works simultaneously to further guide and remove the coal powder, ensuring that dust does not accumulate inside the equipment, thereby improving the overall operating efficiency of the equipment. During operation, to ensure that operators can clearly observe the pulverization operation in dim or dark environments, the equipment is equipped with an explosion-proof lighting lamp 8. This lighting lamp has explosion-proof function, which can effectively avoid the risk of coal powder explosion caused by electric sparks or other reasons, thereby greatly improving the safety of operation. The presence of the explosion-proof lighting lamp 8 not only provides the necessary light source for operators, but also further ensures the safe operation of the equipment and prevents potential explosion accidents caused by sparks generated by electrical equipment.
[0035] Reference Figures 3-5The powder-making operation components include a collection box 9 and a handle 10. The collection box 9 slides inside the machine body 1 and can move smoothly in the horizontal direction for easy cleaning and replacement by the operator. The handle 10 is fixedly connected to the outer wall of the collection box 9, allowing the operator to easily move the collection box 9 out of the machine body 1 for maintenance and cleaning. A suction trough 20 is provided inside the machine body 1 to guide dust into the adsorption tank 6. A sensor alarm is fixedly connected to the inner wall of the collection box 9. Device 11, sensor alarm 11 is used to detect dust inside the collection box 9 and provide warning to the operator. The side wall of the machine body 1 is fixedly connected to a bottle-filling powder tray 19. The inside of the machine body 1 is fixedly connected to a wedge-shaped hopper 21. The wedge-shaped hopper 21 is used to facilitate the operator to put the powder into the powder storage container. The bottle-filling powder tray 19 is used to facilitate the operator to temporarily store and mark the powder. Multiple feeding troughs 12 are opened inside the machine body 1. The feeding troughs 12 are used to put the dust into the collection box 9.
[0036] Specifically, during coal pulverization processes such as coal grinding, sample preparation, and subsequent table cleaning, the output of cylinder 14 drives brush 15 to slide on the worktable. The brush 15 effectively pushes the dust on the worktable to the feeding trough 12. The feeding trough 12 guides the dust to flow smoothly into the collection box 9. The collection box 9 collects and stores the dust to ensure a clean and safe working environment. When the dust in the collection box 9 accumulates to a certain amount, the sensor alarm 11 will detect this change and send a signal to remind the operator to clean it, thus preventing excessive dust accumulation from causing equipment failure or an unsafe working environment.
[0037] Reference Figures 3-5 A limiting plate 13 is fixedly connected to the inner wall of the machine body 1. A cylinder 14 is fixedly connected to the side wall of the machine body 1 to drive the brush 15 to reciprocate. The brush 15 is fixedly connected to the output end of the cylinder 14. The brush 15 is used to push the dust into the material feeding trough 12. A shelf 16 is fixedly connected to the inner wall of the machine body 1. The shelf 16 is used to facilitate the operator to place the sample preparation tool. A baffle 17 is fixedly connected to the top of the shelf 16. A fixing plate 18 is slidably connected inside the baffle 17. The fixing plate 18 is used to limit the position of the sample preparation tool.
[0038] Specifically, during operation, operators sometimes need to place tools, but equipment vibration can cause tools to fall. To solve this problem, the equipment is designed with a storage plate 16, allowing operators to place tools on its surface for convenient storage. To prevent tools from falling due to vibration, the equipment is equipped with a fixing plate 18 and a baffle 17. Operators can simply pull the fixing plate 18 to slide it inside the baffle 17, which quickly limits the tool's position and ensures it stays stable. This greatly improves operational safety and efficiency, allowing operators to focus more on their work while avoiding production delays or unnecessary safety hazards caused by falling tools. This significantly enhances the user experience and safety of the working environment.
[0039] Working Principle: When using this device, a negative pressure is generated by the operation of a fan, forming an airflow channel inside the device. Under the action of the airflow, coal dust will enter the adsorption tank 6 through adsorption port 4 and the suction trough 20, where the dust is temporarily stored. Simultaneously, the explosion-proof lighting 8 provides light for the operator, ensuring clear observation of the pulverizing operation even in dim environments. The explosion-proof lighting 8 effectively avoids the risk of coal dust explosion caused by electrical sparks generated by the lighting fixture itself. While adsorption port 4 is working, adsorption port 7 also operates synchronously. Adsorption port 7 is connected to the collection box, further expelling the dust from the device. When dust accumulates on the worktable, the output end of cylinder 14 drives the brush 15 to slide on the worktable, pushing the dust into the discharge trough 12. Inside, the dust is guided by the feeding chute 12 into the collection box 9. When the amount of dust inside the collection box 9 reaches the required level, the sensor alarm 11 detects this and reminds the operator to clean the dust inside the collection box 9. When the operator needs to place tools, the tools can be placed on the surface of the shelf 16. To prevent the tools from falling due to equipment vibration, the operator can pull the fixing plate 18 to make it slide inside the baffle 17, thereby quickly limiting the tool. When the operator needs to temporarily store the powder, the ground powder is poured into the wedge-shaped hopper 21, and the powder is further introduced into the container through the wedge-shaped hopper 21. After a container is full, the motor inside the powder inlet tray 19 drives it to rotate, thereby quickly changing to the next container for the operator to use, thus greatly improving the convenience of the operator.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
