Description

High-temperature-resistant anti-backfire stranding cage structure

Technical Field

The utility model belongs to the technical field of conveying equipment technique and specifically relates to a hank cage structure of high temperature resistant anti-backfire is related to.

Background

The auger conveyor is also called a screw conveyor, and a rotating screw blade pushes materials to carry out screw conveying, so that the auger conveyor is often used for feeding materials into a boiler. Because the temperature in the hearth is high, and flame often leaps out from the feed inlet, the fire in the conveyor and even in the feed bin is easily caused, so that heavy loss is caused, and the potential safety hazard is very large. On the other hand, because the materials need to be collected and output from the bottom of the storage bin and then conveyed to the top of the hearth for input, the bottom of the storage bin is often higher than the top of the hearth, or a lifting mechanism is adopted to lift the materials to the top of the hearth from a lower position. Moreover, because the temperature of the hearth is high, the hearth and the bin are not arranged in the same vertical direction, and therefore space waste is caused.

Preferably, the blanking area is made of high-temperature-resistant materials.

Preferably, the blanking area is of a detachable structure.

Preferably, the feed hopper bottom is the back taper structure, the axis of draft tube with a side surface of back taper structure is parallel.

The utility model has the advantages that:

1. the guide cylinder of the utility model adopts an inclined arrangement, reduces the space occupation, and conveys the material from the bottom of the feed hopper to a higher position, and the position of the blanking area and the position of the feed hopper are staggered in the vertical direction, so that the relative position arrangement of the feeding area and the hearth area is compact, the high temperature of the hearth does not directly influence the feeding area, and the rationality of the space utilization of the whole boiler equipment is improved;

2. the U-shaped design of the blanking area allows the blanking area to generate larger thermal deformation without influencing material conveying; the blanking area can be disassembled, and if the blanking area is seriously deformed due to high temperature in the long-term use process, the blanking area is convenient to replace;

3. the materials pushed out from the guide cylinder slide into the hearth rapidly along the blanking area under the action of gravity, the stored materials are prevented from being combusted near the outlet of the guide cylinder, the obliquely installed blanking area blocks the flame from jumping up to the outlet of the guide cylinder, the tempering risk is effectively reduced, the flame blocking plate prevents the upward-jumping flame from directly contacting with the guide cylinder, and the temperature near the outlet of the guide cylinder is reduced.

Drawings

Fig. 1 is a structural diagram of a high temperature resistant and backfire proof stranding cage structure of the utility model.

In the figure: the device comprises a feed hopper 1, a triangular plate 101, a baffle plate 102, a guide cylinder 2, a blanking plate 201, a spiral stranding cage 3, a driving motor 4, a blanking area 5 and a fire damper plate 501.

Detailed Description

The present invention will be further described with reference to the following embodiments, so that the technical solution of the present invention can be more easily understood and grasped, rather than being limited to the present invention.

8. Referring to the figure, the high-temperature-resistant and anti-backfire stranding cage structure comprises a feed hopper 1, a guide cylinder 2, a spiral stranding cage 3, a driving motor 4 and a blanking area 5. The guide cylinder 2 is obliquely arranged, the lower end of the guide cylinder is a sealed end, the upper end of the guide cylinder is an open end, the lower end of the feed hopper 1 is of an inverted cone structure, the bottom of the inverted cone structure is arranged at the lower part of the guide cylinder 2, and the axis of the guide cylinder is parallel to one side surface of the inverted cone structure; the inverted cone structure is formed by welding or riveting four triangular plates 101, the four triangular plates 101 form four sides of the inverted cone, the upper surface of the inverted cone is of an open structure, and four vertical baffles 102 are welded or riveted on the periphery above the open structure. The lower extreme of draft tube 2 includes shrouding 201, and shrouding 201 passes through the bolt fastening in the lower extreme of draft tube 2, and driving motor 4 installs on shrouding 201. The spiral stranding cage 3 is coaxially arranged in the guide shell 2 and attached to the inner wall of the guide shell 2, and the driving motor 4 is arranged at the lower end of the guide shell 2 and drives the spiral stranding cage 3 to rotate. The blanking area 5 is of a U-shaped groove structure and is obliquely arranged at the lower part of the opening end of the guide cylinder 2; the blanking area 5 further comprises a fire baffle 501, the fire baffle 501 is located below the upper portion of the guide shell 2, fixed on the lower surface of the U-shaped groove and parallel to the guide shell 2.
