Abstract
Description
Technical Field
[0001] This utility model belongs to the field of dust removal and ventilation technology, and more specifically, it relates to a dust removal and ventilation environmental protection device. Background Technology
[0002] With the acceleration of industrialization and the continuous improvement of urbanization, environmental pollution has become increasingly serious. Among them, dust pollution is one of the important factors affecting air quality and human health. In many industrial production fields, such as mining, cement manufacturing, metallurgical smelting, and machining, a large amount of dust particles are generated during the production process. This dust not only pollutes the surrounding atmospheric environment, but also poses a serious threat to the health of operators. Long-term exposure to high dust environments can easily lead to respiratory diseases such as pneumoconiosis.
[0003] Application number CN202321518176.7 discloses a dust removal, ventilation, and environmental protection device, including a base. An electric telescopic rod is fixedly installed on the top of the base. By starting a fan, air is driven through filter holes for filtration. The filter holes are formed on a sliding plate, which slides along a groove for easy disassembly and installation. Magnetic blocks are set on the top of the sliding plate to increase the stability of the plate installation through magnetic adsorption. The filter layer is composed of porous sponge filling, which can adsorb large particulate impurities in the air. The adsorption layer is composed of activated carbon particles filling, which can adsorb small particulate impurities in the air. The deodorization layer is composed of solid deodorant filling, which can deodorize the air to achieve the effect of air purification.
[0004] Based on the above patent search and understanding of the application of existing dust removal, ventilation and environmental protection equipment: if the ventilation channel is always kept open, dust and other impurities can easily enter the installation location of the equipment when ventilation is not in operation, affecting the cleanliness of its internal environment, and may even damage the equipment or facilities in the installation location. On the other hand, if a more complex sealing structure is used to prevent dust from entering, it may lead to complex structure and inconvenient operation during ventilation, affecting ventilation efficiency. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a dust removal and ventilation environmental protection device. This device solves the problems that if the existing ventilation channel is always kept open, dust and other impurities can easily enter the installation location of the device when ventilation is not in operation, affecting the cleanliness of the internal environment and potentially damaging the equipment or facilities within the installation location. Alternatively, if a complex sealing structure is used to prevent dust from entering, it may result in complex structure and inconvenient operation during ventilation, thus affecting ventilation efficiency.
[0006] The technical solution adopted in this utility model is as follows:
[0007] A dust removal, ventilation, and environmental protection device includes an outer pipe; an inner pipe is inserted into the front end of the outer pipe, a conical groove is provided in the middle of the inner part of the outer pipe, a Y-shaped frame A is fixedly installed at the rear end of the inner part of the outer pipe, a limit plug A is slidably connected to the front end of the inner part of the Y-shaped frame A, a spring A is sleeved on the middle and rear end of the limit plug A, the front end of the spring A is in contact with the middle and front end of the limit plug A, the rear end of the spring A is in contact with the front end of the Y-shaped frame A, and a fan is fixedly installed at the front end of the inner pipe. When the spring A is in the extended state, the front end of the limit plug A is tightly in contact with the inner side of the conical groove of the outer pipe.
[0008] According to one embodiment of the present invention, a cylinder is provided at the bottom front end of the outer tube, and the front end of the cylinder is fixedly connected to the bottom rear end of the inner tube.
[0009] According to one embodiment of the present invention, a tapered groove is provided at the rear end of the inner tube, and a Y-shaped bracket B is fixedly installed at the front end of the inner tube.
[0010] According to one embodiment of the present invention, a limiting plug B is slidably connected to the rear end position of the Y-shaped frame B, and a spring B is sleeved at the front end position of the limiting plug B.
[0011] According to one embodiment of the present invention, the rear end position of the spring B is aligned with the rear end position of the limiting plug B, and the front end position of the spring B is aligned with the rear end position of the Y-shaped frame A.
[0012] According to one embodiment of the present invention, when the spring B is in the extended state, the rear end of the limiting plug B is tightly fitted to the inner side of the conical groove of the inner tube.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] When ventilation is needed, the cylinder is activated to retract, the inner and outer pipes are tightly connected, the limit plug disengages from the conical groove, and a through area is formed between the inner and outer pipes. Then, the fan is started to perform ventilation. The operation is simple, can quickly achieve the ventilation function, and ensures high efficiency.
[0015] After ventilation is completed, the cylinder extends and the inner tube disengages from the outer tube. The spring returns to its original position, causing the limit plugs to tightly fit the conical grooves of the outer and inner tubes, sealing the interiors of the outer and inner tubes. This effectively prevents dust from entering the installation location where the outer tube is connected, ensuring a clean internal environment and avoiding adverse effects of dust on the equipment or facilities within the installation location.
[0016] The equipment has a compact overall structure and a reasonable layout of components. It makes full use of the internal space of the outer and inner pipes, achieving flexible opening and closing of the ventilation channel within a limited space while ensuring good sealing performance. Compared with traditional ventilation equipment, this structural design saves more space and is more convenient to install and use.
[0017] The equipment has a relatively simple structure. Its main components, such as cylinders, blowers, limit plugs, and springs, are common mechanical parts that are easy to manufacture and obtain, which reduces the manufacturing cost of the equipment. At the same time, its simple operation and convenient maintenance can reduce the later maintenance costs. Attached Figure Description
