Description

Technical Field

[0001] This invention belongs to the technical field of coal preparation protection equipment, specifically a protective device for coal preparation plants and its usage method. Background Technology

[0002] Coal preparation, also known as coal washing, is the process of separating clean coal from raw coal to meet the quality requirements of users. Coking coal has certain requirements for ash and sulfur content, and must use clean coal that has been washed. The petrographic composition of coal, as well as the quantity, type, properties and distribution of minerals in the coal, are all factors that affect the coal's washability.

[0003] However, in existing technologies, scraper conveyors are typically used to transport coal and mineral materials during the coal preparation process. Due to the limitations of their actual structure, existing scraper conveyors tend to generate significant noise during operation. This high noise level can be harmful to the health of operators. Furthermore, the material scrapes against internal components during operation, which can generate high temperatures and potentially lead to spontaneous combustion, posing a significant safety hazard to construction. Additionally, the material transport process generates dust, which negatively impacts the overall construction environment. Summary of the Invention

[0004] The purpose of this invention is to provide a protective device for coal preparation plants and its usage method that can effectively reduce the noise generated by existing scraper conveyor equipment, effectively prevent spontaneous combustion of materials during transportation, and effectively prevent excessive dust dispersion, thus ensuring the cleanliness of the overall construction process.

[0005] The technical solution adopted in this invention is as follows: A protective device for a coal preparation plant, comprising: a first functional mechanism, the first functional mechanism including a base, two bases being provided in total, a set of top blocks being slidably inserted inside each base, two top blocks being provided in each set, an adjusting block being rotatably connected between the two sides of each top block relative to the inner surface wall, a liquid storage frame being fixedly connected between the tops of the four adjusting blocks, two sliding rods being slidably inserted between the two sides of the liquid storage frame relative to the inner surface wall, and a movable frame being sleeved on the outer surface of each sliding rod;

[0006] The second functional mechanism includes a protective frame, which is fixedly connected to the top of two movable frames. Micro-perforated plates are fixedly connected to the inner walls of both sides of the protective frame. Two mounting brackets are fixedly connected to the bottom of the protective frame. Each mounting bracket has a limit threaded rod threadedly connected to its bottom. The top end of each limit threaded rod extends into the interior of the protective frame, and a support plate is rotatably connected to the top end of each limit threaded rod.

[0007] The third functional mechanism is set on the protective frame. The third functional mechanism includes a connecting frame and a cooling component. Top plates are fixedly connected to both outer surfaces of the connecting frame. A clip is fixedly connected to one outer surface of each top plate. The cooling component is set on the top plate.

[0008] In each group of two top blocks, a connecting plate is fixedly connected between their opposite outer surfaces. Two hydraulic cylinder bodies are fixedly connected to the bottom surface inside each base. The output end of each hydraulic cylinder body is fixedly connected to the bottom of the corresponding connecting plate.

[0009] The liquid storage frame has an injection pipe connected to one outer surface and a drain pipe connected to the bottom.

[0010] The liquid storage frame has two movable openings at the top, and the top of each movable frame slides through the corresponding movable opening. Multiple push plates are fixedly connected at equal intervals to the outer surfaces of the two movable frames.

[0011] Each of the slide rods has a pressure plate fixedly connected to both ends, and a limiting spring is slidably sleeved on the outer surface of each slide rod near the edges of both ends.

[0012] The protective frame has flow channels on its inner bottom surface near both sides, and a flow block is fixedly connected to the bottom of the protective frame.

[0013] One end of the connecting frame is fixedly connected to a connecting pipe by bolts, and two clips are slidably inserted into the top of the protective frame.

[0014] The cooling component includes a top tube and a liquid guiding frame. There are two top tubes, which are connected and located at the top of the connecting frame. A pressurizing frame is connected between the top ends of the two top tubes. There are multiple liquid guiding frames, which are equidistantly connected and located at the bottom of the connecting frame. A liquid dispensing frame is connected to one outer surface of each liquid guiding frame, and multiple L-shaped strips are fixedly connected at equal intervals to the bottom of each liquid dispensing frame.

[0015] The pressurizing frame is equipped with a one-way valve at the top, and each of the liquid dispensing frames has a drain port at the bottom.

[0016] A method for using protective equipment in a coal preparation plant includes the following steps:

[0017] S1. Initial Protection: Adjust the number of devices according to actual usage. Securely connect the connecting frame and protective frame with bolts, allowing multiple devices to be assembled for use. This ensures the equipment can accommodate existing scraper conveyors of different specifications. Inject an appropriate amount of water into the storage frame via the injection pipe. Place the protective frame under the existing scraper conveyor. Control the start of the hydraulic cylinder, which, in conjunction with the connecting plate, adjusts the height of the corresponding top block. This allows the adjusting block to adjust the angle of the storage frame, and the sliding rod, via the moving frame, adjusts the protective frame. By using an angle, and then adjusting the limit threaded rod by rotation, the limit threaded rod can move and adjust the support plate, allowing the limit threaded rod to press the support plate against the bottom of the protective frame. This enables the first and second functional mechanisms to provide a certain degree of support for the existing scraper conveyor equipment. At the same time, the vibration generated by the operation of the existing scraper conveyor equipment can be transmitted to the slide rod and push plate through the moving frame. Under the positional constraints of the limit spring and water resources, the water resources, in conjunction with the push plate, and the slide rod, in conjunction with the pressure plate and limit spring, can effectively reduce the vibration of the existing scraper conveyor equipment.

[0018] S2. Adjustment and Protection: Seal one end of the end connecting frame and connect it to the existing water supply equipment through the connecting pipe. When water is injected into the connecting frame, it will be injected into the dispensing frame through the liquid guide frame. The water can then be delivered to the top of the L-shaped strip through the drain port and flow down between adjacent L-shaped strips. This creates a water film between the adjacent L-shaped strips, which can effectively block the transmission of noise generated by the operation of the existing scraper conveyor and reduce the temperature around the existing scraper conveyor.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] In this invention, the number of devices can be increased or decreased according to actual usage. Bolts securely connect the connecting frame and the protective frame, allowing multiple devices to be assembled for use. This enables the equipment to meet the needs of existing scraper conveyor equipment of different specifications. A suitable amount of water is injected into the storage frame through the injection pipe. The protective frame is placed below the existing scraper conveyor. The hydraulic cylinder is then activated, moving in conjunction with the connecting plate to adjust the height of the corresponding top block. This allows the adjusting block to effectively adjust the angle of the storage frame. The sliding rod, via the moving frame, effectively adjusts the angle of the protective frame. Rotating the adjusting limit threaded rod moves the support plate, pressing it against the bottom of the protective frame. This provides a certain degree of support for the existing scraper conveyor equipment through the first and second functional mechanisms. Simultaneously, the vibrations generated during the operation of the existing scraper conveyor equipment are effectively mitigated by the moving frame. The water is transferred to the slide bar and push plate. Under the positional constraints of the limit spring and water supply, the water supply, in conjunction with the push plate and the slide bar, in conjunction with the pressure plate and limit spring, effectively reduces the vibration of the existing scraper conveyor equipment, thereby effectively reducing vibration and noise. Simultaneously, one end of the end connecting frame is sealed, and a connecting pipe connects it to the existing water supply equipment. When water is injected into the connecting frame, it flows through the liquid guide frame into the liquid distribution frame, allowing the water to be delivered to the top of the L-shaped strips through the drain port. The water then flows down between adjacent L-shaped strips, forming an effective water film. This water film effectively blocks the transmission of noise generated by the existing scraper conveyor equipment and effectively reduces the ambient temperature, ensuring that materials are less likely to spontaneously combust during transport. The flowing water also effectively reduces dust from materials, ensuring a clean construction environment and enabling the equipment to perform its functions efficiently. Attached Figure Description

[0034] The following is a detailed description of the method of using a protective device for a coal preparation plant provided by an embodiment of the present invention. The method of use includes the following steps:

[0035] Step 1, Initial Protection: Adjust the number of devices according to actual usage. Securely connect the connecting frame 301 and the protective frame 201 with bolts, allowing multiple devices to be assembled for use. This ensures the equipment can meet the needs of existing scraper conveyors of different specifications. Inject an appropriate amount of water into the storage frame 104 through the injection pipe 110. Place the protective frame 201 under the existing scraper conveyor. Then, control the start of the hydraulic cylinder body 112, which, in conjunction with the connecting plate 113, moves to adjust the height of the corresponding top block 102.

Finally, rotate... Adjusting the limiting threaded rod 205 allows the limiting threaded rod 205 to effectively move and adjust the support plate 206, enabling the limiting threaded rod 205 to press the support plate 206 against the bottom of the protective frame 201. This allows the first functional mechanism 1 and the second functional mechanism 2 to provide a certain degree of support for the existing scraper conveyor equipment. Simultaneously, the vibration generated by the operation of the existing scraper conveyor equipment can be effectively transmitted to the slide rod 106 and push plate 109 through the moving frame 105. Under the positional restriction of the limiting spring 107 and the water resource, the water resource, in conjunction with the push plate 109 and the slide rod 106, in conjunction with the pressure plate 108 and the limiting spring 107, can effectively reduce the vibration of the existing scraper conveyor equipment, thereby effectively reducing the vibration noise of the existing scraper conveyor equipment.

[0036] Step 2, Adjustment and Protection: Seal one end of the end connecting frame 301, and connect it to the existing water supply equipment through the connecting pipe 309. When water is injected into the connecting frame 301, it will flow into the distributing frame 304 through the liquid guide frame 310.

This water film can effectively block the transmission of noise generated by the existing scraper conveyor equipment, and effectively reduce the temperature around the existing scraper conveyor equipment, ensuring that the material is not prone to spontaneous combustion during transportation. At the same time, the flowing water can effectively reduce the flying of material dust, ensuring a clean construction environment and enabling the equipment to perform its functions efficiently.
