Description

Technical Field

[0001] The utility model relates to the technical field of ash cleaning, in particular to a ash cleaning device for an ash discharge valve of a desulfurization ash silo. Background Art

[0002] Star feeder, also known as star discharger or electric feeder, is a special unloading equipment. It is usually composed of a rotor impeller with several blades, a housing, a seal, a reducer, an electric motor, etc. Its working principle is to use the gravity of the material in the upper silo to fill the gap between the blades, and discharge the material from the upper part as the blades rotate. The seal of the star feeder is mainly divided into two parts: the seal between the impeller and the housing and the seal of the end covers on both sides. The seal between the impeller and the housing is mainly based on the material seal, while the sealing methods of the end covers on both sides include compressed packing, oil seal and gas seal.

[0003] However, due to the high frequency of ash discharge from the star-type feeder, the packing is not sealed tightly, causing the desulfurization ash to leak from the non-motor side. The packing needs to be replaced frequently, which not only wastes time but also increases a lot of costs during use. Therefore, it is necessary to solve the problem of dust leakage from the packing. The dust can be collected and cleaned at the packing to avoid clogging the packing with dust. Utility Model Content

[0008] Through the above technical scheme, the flange is fixed at the leakage port by setting a fixing column to preliminarily block the dust. By setting a threaded ball valve, when dust condenses inside the cleaning box and the blower cannot clean the dust inside, the threaded ball valve is opened through the valve switch to allow the dust inside the cleaning box to flow down.

[0009] As a further improvement of the above solution, the feed port is arranged at the center of the top of the feed box.

[0010] As a further improvement of the above solution, the feeding mechanism includes a motor, the output end of the motor is transmission-connected to a rotating rod, and the surface of the rotating rod is fixedly connected to a transmission blade.

[0011] As a further improvement of the above solution, the motor is arranged on the left side of the feed box, the number of the conveying blades is set to be several, and the several transmission blades are evenly distributed on the surface symmetrically around the center of the rotating rod surface.

[0012] As a further improvement of the above solution, the rotating blades are arranged inside the feed box, and one end of the rotating rod is arranged inside the bearing.

[0013] As a further improvement of the above solution, the feeding mechanism includes a feeding box, a feeding port is arranged on the top of the feeding box, a through hole is opened on the surface of the feeding box, and an ash conveying pipe is fixedly connected to the surface of the through hole.

[0014] Through the above technical solution, by arranging and installing an ash conveying pipe on the top of the dust cleaning box and connecting it to the inside of the feed box and conveying the dust to the inside of the feed box through a blower, the dust is prevented from clogging the device.

[0015] As a further improvement of the above solution, the bottom of the feed box is arranged on the top of the feed port, one end of the ash conveying pipe is arranged on the surface of the feed port, and the other end of the ash conveying pipe is fixedly connected to the top of the ash cleaning box.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The utility model provides a dust cleaning box and preliminarily blocks the dust by arranging a flange on the right side of the feed box. Some dust leaks into the dust cleaning box through the right side of the feed box. An ash conveying pipe is installed on the top of the dust cleaning box and connected to the inside of the feed box and transported to the inside of the feed box by a blower, thereby preventing the dust from blocking the device.

[0018] The utility model provides a threaded ball valve, when dust is condensed inside the dust cleaning box and the blower cannot completely remove the dust inside, the threaded ball valve is opened through a valve switch to allow the dust inside the dust cleaning box to flow down.
