Description
Technical Field
[0001] This utility model relates to a dust collector, and more particularly to a flip-top silo top quick-repair and quick-change filter cartridge dust collector consisting of a top cover, a housing, a jet blowing device, a fan, and a dust collection structure. Background Technology
[0002] Chinese patent CN204933113U discloses a dust collector for the top of a cement silo. Its structural features include a top cover, a housing, a pulse-jet cleaning system, a fan, and a dust collection structure. The top cover is located on the upper part of the housing. A fan is installed outside the housing, with its inlet connected to the dust collection structure inside. The pulse-jet cleaning system is located above the dust collection structure inside the housing, and a dust hopper is installed below it. An inspection ladder is also installed outside the housing. Because this structure uses multiple filter bags, and the pulse-jet cleaning system consists of an air tank, a pulse valve, and a jet pipe (one air tank, one pulse valve, and one jet pipe), with multiple nozzles corresponding to the filter bags on each jet pipe, the structure is quite large and complex, placing a significant load on the silo top. Furthermore, replacing the filter bags requires removing the jet pipes, making the process time-consuming and labor-intensive. Summary of the Invention
[0003] The purpose of this utility model is to provide a flip-top silo top quick-repair and quick-replacement filter cartridge dust collector with a relatively simple and compact structure and a smaller load on the silo top.
[0004] To achieve the above objectives, this utility model provides a flip-top type quick-repair and quick-replacement filter cartridge dust collector, which consists of an upper cover, a housing, a jet-blowing device, a fan, and a dust collection structure. The upper cover is located on the upper part of the housing. A fan is installed outside the housing, and the fan's air inlet is connected to the dust collection structure inside the housing. A jet-blowing device is installed above the dust collection structure inside the housing, and a dust hopper is installed below the dust collection structure. A fan is installed on the upper part of the outer surface of the upper cover, and a portion of the outer surface of the upper cover forms an air outlet with the lower and upper volutes. A jet-blowing device is installed on the upper part of the inner surface of the upper cover, and the nozzle of the jet-blowing device extends into the dust collection structure. The upper cover is connected to a lifting cylinder through a support.
[0005] The fan consists of an impeller, a motor, an upper volute, a lower volute, and guide plates. The motor is mounted on the outer surface of the upper volute, and the motor shaft passes through the upper volute and connects to the impeller mounted below the upper volute, so that the lower end of the impeller is placed inside the lower volute and moves relative to it. Multiple guide plates are evenly distributed between the upper and lower volutes, so that the impeller is placed in an annular ring formed by the multiple guide plates, and a channel is formed between two adjacent guide plates to communicate between the impeller and the outside. The center line of the channel and the center line of the air inlet on the impeller form an L shape.
[0006] The upper volute is designed to be curved, and a hole is provided in the middle of the upper volute to facilitate the passage of the rotating shaft and to allow the installation of the bearing seat.
[0007] The lower volute is configured as a ring.
[0008] The guide plate is configured as a curved surface, and its unfolded surface is trapezoidal.
[0009] The jetting device consists of a pulse valve, an air tank, a jetting pipe, and an ejector port. The pulse valve is installed on the air tank, the jetting pipe is installed on the lower surface of the air tank and communicates with the inside of the air tank, and the ejector port is located below the jetting port of the jetting pipe.
[0010] The ejector port includes a connecting plate and a nozzle. The nozzle, which has a frustum-shaped axial cross section, is connected to the lower surface of the air bag through at least two connecting plates. The upper end of the nozzle is kept at a specified distance from the nozzle of the blowpipe to prevent secondary dust generation.
[0011] The lifting cylinder is mounted on a partition that can fix the dust collection structure.
[0012] The dust collection structure is a filter cartridge.
[0013] With this structure, a fan is installed on the upper part of the outer side of the cover, and a jet-blowing device is installed on the upper part of the inner side of the cover. The nozzle of the jet-blowing device extends into the filter cartridge of the dust collection structure, and the upper cover is connected to the lifting cylinder through a support. This achieves a simpler and more compact structure, reduces the load on the top of the silo, and allows for quick repair and replacement of the filter cartridge. Attached Figure Description
