TECHNICAL FIELD
[0001] The present application relates to the field of conveyors, in particular to a sealing device for the head and tail of a conveyor. BACKGROUND
[0002] In traditional conveyor designs, the head and tail sections often lack dedicated sealing devices. This design may have met basic needs in early industrial production, but as industrial production continues to develop and environmental protection requirements become increasingly stringent, its limitations gradually emerge. Due to the lack of effective sealing measures, the conveyor is prone to generate a large amount of dust leakage during operation, especially in the head and tail sections. This dust leakage not only causes serious pollution to the working environment, but also directly threatens the health of operators. Long-term exposure to high-concentration dust environments can cause operators to suffer from occupational diseases such as pneumoconiosis and respiratory diseases, severely affecting their quality of life and work efficiency. In addition, dust leakage can also cause dust accumulation inside the equipment, affecting the normal operation of the conveyor. For example, dust can enter critical components such as bearings and gears, accelerating their wear and tear, and even causing equipment failure, increasing maintenance frequency and cost, and shortening the service life of the equipment. More seriously, the spread of dust can also cause secondary pollution to the surrounding environment, especially in industries such as mining, building materials, and chemicals, which may contain harmful substances in the dust, causing long-term harm to soil, water sources, and air quality, not meeting the modern industry's requirements for clean production and environmental protection.
[0003] The root cause of these problems lies in the neglect of sealing function in traditional conveyor designs. Early conveyors mainly focused on the efficiency of material transportation, and insufficient consideration was given to dust control and environmental protection needs. As industrial production scales expand and environmental regulations become increasingly stringent, the shortcomings of this design gradually emerge. For example, in the mining industry, conveyors often need to handle large amounts of ore and coal, which are prone to generate dust during transportation. If there is no effective sealing device, the dust leakage problem will become particularly serious. In the building materials industry, the transportation of powdery materials such as cement and lime also generates a large amount of dust, which not only affects the cleanliness of the production environment, but also may cause safety accidents such as explosions. In addition, the structural design of the head and tail sections of traditional conveyors is relatively simple during operation, lacking effective barriers to dust dispersion, further exacerbating the problem. For example, the head and tail are usually designed in an open manner, and material entering and exiting the conveyor is prone to generate dust, while simple structures such as traditional baffles or rubber curtains cannot completely block the spread of dust, making it difficult to fundamentally solve the problem of dust leakage.
[0004] In order to solve the many problems caused by the lack of sealing devices in the head and tail of traditional conveyors, it is of great practical significance to develop a new type of sealing device. CONTENT OF THE INVENTION
[0005] The purpose of this application is to overcome at least one deficiency of the existing technology and provide a conveyor head and tail sealing device. This sealing device, through a combination design of multiple components such as top sealing, side sealing, rear sealing, and sealing curtain, can effectively prevent dust leakage, improve the working environment, protect the health of operators, and effectively block dust generated during material entry and exit. At the same time, the installation and maintenance of the sealing device are also simpler, which can reduce the operating costs of enterprises.
[0006] To achieve the above objectives, this application discloses a conveyor head and tail sealing device, which includes a top plate, two oppositely arranged side plates and an end plate, wherein the end plate and the opposite side plate together define the structure of the cover.
[0007] The other side plate opposite the end plate is an open structure, forming an inlet to allow materials to smoothly enter or leave the conveyor. An openable observation window is provided on the end plate, with a sealing strip along its outer edge to ensure the enclosure remains airtight whether open or closed, allowing operators to monitor the equipment's operating status in real time.
[0008] The top plate is equipped with a dust suction port, which is connected to an external dust collection device through a pipe to effectively collect and treat dust inside the enclosure, reduce dust accumulation inside the enclosure, thereby reducing the risk of equipment failure and improving the working environment.
[0009] A curtain is installed at the top of the entrance. The curtain consists of several flexible sheet-like structures, with the lower ends of the flexible sheet-like structures hanging freely. The curtain, in conjunction with the entrance, effectively reduces the entry of external airflow, dust, or impurities into the enclosure when the equipment is running, while providing basic sealing performance for the entrance when not in use.
[0010] Furthermore, a fixed guide wheel is installed at the bottom of the side plate. The guide wheel is connected to the side plate through a bracket. The bracket is adjustable so as to make precise adjustments according to the height and position of the conveyor.
[0011] Furthermore, the top plate, side plates, and end plates are fixedly connected by connectors, which adopt bolt or snap-fit structures to ensure the overall stability and sealing of the cover.
[0012] Furthermore, a sealing strip is provided at the connection between the top plate and the side plate. The sealing strip is made of high-temperature resistant and wear-resistant rubber material to further enhance the sealing effect of the cover and prevent dust from leaking from the connection.
[0013] Furthermore, the observation window on the end plate adopts a double-layer glass design, with the inner layer being explosion-proof glass and the outer layer being a transparent and wear-resistant material, in order to improve the safety and durability of the observation window.
[0014] Compared with the prior art, the conveyor head and tail sealing device has the advantages that: the combination of the top plate, the side plate and the end plate forms a closed cover structure, which can effectively prevent dust from leaking from the head and tail of the conveyor; the observation window arranged on the end plate is designed to be openable, which facilitates the operator to monitor the running state of the equipment in real time, and does not affect the sealing performance; after the dust suction interface on the top plate is connected with the external dust suction equipment, the dust in the cover body can be timely extracted, so that the dust accumulation is avoided, thereby ensuring the normal operation of the conveyor and reducing the environmental pollution; in addition, the hanging curtain installed at the inlet and the guide wheel arranged at the bottom end of the side plate further enhance the sealing effect and practicability of the device, which is suitable for the industry with serious dust pollution, and has high practical value and popularization significance.
[0015] The above-listed beneficial effects are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementation manners will be further disclosed in the embodiments or other description parts of the present application. BRIEF DESCRIPTION OF DRAWINGS
