Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a dust removal device in the process of FRP profile pultrusion production and cutting. Background Art

[0002] FRP profiles have been widely used due to their advantages of light weight, high strength, corrosion resistance, insulation, heat insulation, and non-magnetization. The continuous length of profiles coming out of the dust removal device line during the pultrusion production cutting process needs to be cut to a fixed length according to customer requirements. Due to the characteristics of FRP materials, the diamond grinding wheel is used for cutting, and a large amount of ultra-fine dust will be generated during the cutting process. These dusts contain a large amount of glass fiber fragments, which are harmful to the human body and must be removed to meet safety and environmental protection requirements.

[0003] The existing patent (Announcement No.: CN202023193511.X) discloses a dust removal device for the FRP profile pultrusion production and cutting process. By setting a support frame, a collection mechanism, an exhaust mechanism, an upper dust hood, a cutting machine, a cutting blade, a lower dust hood, a first air pipe, a connecting mechanism, a second air pipe and a third air pipe, the cutting machine adds a lower dust hood on the basis of the upper dust hood currently used, which greatly improves the dust collection effect. The width of the dust collection slit between the lower dust hood and the upper dust hood is controlled at 20 to 50 mm, and the wind speed of the slit is increased. A more effective coated filter element for ultra-fine glass fiber powder is used instead of a filter bag. The dust removal efficiency of the filter element should reach 99.99%, and the wind pressure of the dust removal fan is 100 to 1500Pa, which has a better dust removal effect. In the process of implementing this solution, it was found that the following problems exist in the prior art and have not been well solved:
