Description

Technical Field

[0001] This utility model belongs to the field of smelting waste slag conveying technology, specifically relating to a dust-proof smelting waste slag conveying equipment. Background Technology

[0002] Smelting slag is a byproduct of metallurgical processes, typically generated during ore smelting, metal refining, or other metal processing. It consists of the portion that failed to be converted into the target metal or compound during the smelting reaction, containing a significant amount of minerals, unused metals, and other impurities.

[0003] Some smelting waste can be recycled and reused, such as for extracting non-ferrous metals or for use in building materials. Therefore, it is necessary to use conveying equipment to transport the waste to recycling and processing centers, which can promote the maximization of resource utilization.

[0004] However, these waste residues become very dry and fine after cooling, and are prone to generating a large amount of dust during conveying, transfer and unloading. Most existing ordinary belt conveyors are open or semi-open structures, which cannot effectively curb the spread of dust. This dust not only causes serious pollution to the working environment and endangers the health of operators, but also damages the ecological environment around the factory area. Utility Model Content

[0005] The purpose of this invention is to provide a dust-proof smelting waste conveying equipment that can seal the conveyor belt of the equipment, effectively preventing dust pollution. This not only protects the health of factory workers but also improves the overall air quality.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A dust-preventing smelting waste conveying device includes a conveyor frame and a conveyor belt installed inside the conveyor frame. A feeding hopper is installed at the top of one end of the conveyor frame, and a fully enclosed discharge bin is installed at the bottom of one side of the conveyor frame. The discharge bin has a discharge port at its bottom. Enclosed dust covers are installed at the top and bottom of the conveyor frame along the conveyor belt path. At least one dust collection port is provided at the top and bottom of the dust cover. The dust collection port is connected to a negative pressure dust collection mechanism through a suction pipe. The negative pressure dust collection mechanism includes a dust collection box, a suction fan, and a filter element. The dust collection box is located on one side of the conveyor frame and is connected to the dust collection port through a suction pipe. The suction end of the suction fan is connected to the filter element installed inside the dust collection box.

[0008] Preferably, a pipe is installed at the top of the inner wall of the feeding hopper, and a water spray head is connected to the bottom of the pipe. A water tank is installed on one side of the feeding hopper, and a water pump is installed at the top of the water tank. The pumping end of the water pump is connected to the top of the water tank through a water pipe, and the water delivery end at the top of the water pump is connected to one end of the pipe through a water pipe.

[0009] Preferably, an observation window is provided on one side of the water tank, and a water injection pipe is connected to the top of the water tank.

[0010] Preferably, the filter element is detachably installed on the inner wall of the dust collection box, and the filter element is made of fiber material.

[0011] Preferably, a guide plate is installed on the inner wall of the bottom dust cover, and the guide plate is installed obliquely on the inner wall of the dust cover.

[0012] Preferably, a sealing door panel is connected to one side of the dust collection box via a hinge, and a handle is connected to one side of the sealing door panel.

[0013] Preferably, a closed cover is installed at one end of the inner side of the conveyor frame, and the closed cover is located at one end wrapped around the conveyor belt.

[0014] The technical effects achieved by this utility model are as follows:

[0015] In this invention, when conveying waste residue, the waste residue can first be added to the top of the conveyor belt through a feeding hopper. Simultaneously, the conveyor belt transports the waste residue. During the conveying process, the entire process is isolated from the outside world under a closed dust cover, preventing waste residue dust from escaping. At the same time, a suction fan operates, drawing air out of the dust collection box through a filter element and creating negative pressure inside the dust collection box. This negative pressure is then drawn into the dust collection box through a connected suction pipe. Thus, the waste residue is conveyed in a sealed manner through the closed dust cover, preventing waste residue dust from spreading into the air during transport and reducing air pollution.

[0016] In this invention, after the waste residue is transported to the other end of the conveyor belt, it will be unloaded through the unloading hopper. During the unloading process, a water pump is operated at the same time. The water pump will pump the water inside the water tank into the pipeline, and then spray water mist downward from the bottom spray nozzle. The water mist particles will coat the falling waste residue, and the impact dust generated during unloading will be effectively suppressed through the wetting effect. Attached Figure Description

Detailed Implementation

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-4 As shown, a dust-preventing smelting waste slag conveying device includes a conveyor frame 1 and a conveyor belt 101 installed inside the conveyor frame 1. A feeding hopper 102 is installed on the top of one end of the conveyor frame 1, and a fully enclosed discharge bin 103 is installed on the bottom of one side of the conveyor frame 1. The bottom of the discharge bin 103 has a discharge port. Enclosed dust covers 104 are installed on the top and bottom of the conveyor frame 1 along the path of the conveyor belt 101. At least one dust collection port 106 is provided on the top and bottom of the dust cover 104. The dust collection port 106 is connected to a negative pressure dust collection mechanism through a dust suction pipe 105. By setting the enclosed dust covers 104 on the top and bottom of the conveyor belt 101, the dust in the waste slag conveying process can be effectively isolated from the outside world, avoiding dust leakage into the air and polluting the surrounding environment.

[0025] like Figure 3 As shown, the negative pressure dust collection mechanism includes a dust collection box 201, a suction fan 202, and a filter element 203. The dust collection box 201 is located on one side of the conveyor frame 1 and is connected to the dust collection port 106 through a suction pipe 105. The suction end of the suction fan 202 is connected to the filter element 203 installed inside the dust collection box 201. Under the suction force of the suction fan 202, a negative pressure is generated inside the dust collection box 201, which further sucks up the dust and collects it inside the dust collection box 201 for centralized processing, reducing the dispersion of dust and effectively improving the conveying environment.

[0026] like Figure 4As shown, a pipe 301 is installed on the top of the inner wall of the feeding hopper 103, and a water spray head 302 is connected to the bottom of the pipe 301. A water tank 303 is installed on one side of the feeding hopper 103, and a water pump 304 is installed on the top of the water tank 303. The water pump 304's pumping end is connected to the top of the water tank 303 through a water pipe, and the water pump 304's delivery end is connected to one end of the pipe 301 through a water pipe. Through the connection between the pipe 301 installed on the top of the feeding hopper 103 and the water spray head 302, water is sprayed onto the waste residue, which can effectively wet the surface of the waste residue, making the dust heavier and less likely to fly away, reducing the dust generated during the conveying and feeding of the dried waste residue, and reducing environmental pollution.

[0027] like Figure 2 and Figure 4 As shown, an observation window 401 is provided on one side of the water tank 303, and a water injection pipe 402 is connected to the top of the water tank 303. The observation window 401 can help the operator to check the water level inside the water tank 303 at any time, ensuring that the water level in the water tank 303 is kept within a reasonable range, and avoiding the shutdown of the water spray system due to insufficient water supply. The water injection pipe 402 makes it more convenient to replenish the water supply, especially when the water level drops after long-term operation, water can be quickly and conveniently added to the water tank 303 to maintain the normal operation of the water spray system.

[0028] like Figure 3 As shown, the filter element 203 is detachably installed on the inner wall of the dust collection box 201. The filter element 203 is made of fiber material. The filter element 203 can prevent dust from entering the inside of the suction fan 202, reducing the risk of wear and blockage of the suction fan 202, thereby extending the life of the suction fan 202. In addition, the fiber material not only has high filtration capacity, but also maintains good air circulation after long-term use, ensuring stable airflow in the dust collection system and preventing excessive resistance. The detachable filter element 203 can be easily removed and replaced when it is blocked or damaged by dust, reducing downtime and improving system maintainability.

[0029] like Figure 3 As shown, a guide plate 5 is installed on the inner wall of the bottom dust cover 104. The guide plate 5 is installed at an angle on the inner wall of the dust cover 104. The guide plate 5 can effectively guide the airflow inside the dust cover 104, reduce the time that dust stays in the dust cover 104, prevent dust from flowing back or depositing inside the dust cover 104, and help waste dust to be drawn more smoothly from inside the dust cover 104 into the dust collection box 201.

[0030] like Figure 1As shown, a sealing door 6 is connected to one side of the dust collection box 201 via a hinge, and a handle is connected to one side of the sealing door 6. The sealing door 6 not only maintains the airtightness of the dust collection box 201, but also makes it easy for staff to open and close the sealing door 6, facilitating internal inspection, cleaning and maintenance. The handle design makes operation simpler and reduces the difficulty and time of operation.

[0031] like Figure 1 As shown, a closed cover 7 is installed at one end of the inner side of the conveyor frame 1. The closed cover 7 is located at one end of the conveyor belt 101. The closed cover 7 can reduce the risk of dust or harmful substances leaking from the conveyor belt 101 during the conveying of waste residue, prevent waste residue dust from spreading into the air during the conveying process, reduce air pollution, and ensure a clean production environment.

[0032] The working principle of this utility model is as follows: When conveying waste residue, the waste residue is first added to the top of the conveyor belt 101 through the feeding hopper 102. At the same time, the conveyor belt 101 will transport the waste residue. During the conveying process, the entire conveying process is isolated from the outside world under the closed dust cover 104 to prevent the waste residue dust from being scattered. At the same time, the suction fan 202 is running. The suction fan 202 will draw out the air inside the dust collection box 201 under the filtration of the filter element 203, and create a negative pressure inside the dust collection box 201. Then, the dust isolated inside the dust cover 104 can be sucked into the dust collection box through the connected suction pipe 105. Inside the dust bin 201, the waste residue is conveyed in a closed manner through the dust cover 104 during the conveying process, which prevents the waste residue dust from spreading into the air during the conveying process and reduces air pollution. After the waste residue is conveyed to the other end of the conveyor belt 101, the waste residue will be unloaded through the unloading bin 103. During the unloading process, the water pump 304 is running at the same time. The operation of the water pump 304 will pump the water inside the water tank 303 into the pipe 301, and then spray water mist downward from the water spray head 302 at the bottom. The water mist particles will coat the falling waste residue, and the impact dust generated during unloading will be effectively suppressed through the wetting effect.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
