Abstract
Description
Technical Field
[0001] This utility model relates to the field of silo technology, specifically to a silo with a split-type partition mechanism. Background Technology
[0002] A cement production line is a general term for a complete set of industrial equipment and processes used to produce cement. The modern mainstream adopts the new dry process, the core of which can be summarized as "two grindings and one calcination": First, raw materials such as limestone are crushed, ground and homogenized into raw meal; then, the raw meal is preheated, decomposed and calcined at high temperature in the kiln system to become clinker; finally, the clinker is mixed with gypsum and other materials and ground to produce cement. In the cement production process, as the raw materials are crushed, they need to be transported and processed in multiple stages. When the material is fed to the high-temperature calcination stage, a large amount of hot air will be generated. When the powder falls directly from above, it will be carried away by the hot air and dispersed in all directions. Therefore, it is usually necessary to use a feeding hopper for feeding. However, some existing feeding hoppers have open bottom openings. When the material is small, the rising hot air can easily cause the powder to accumulate inside the feeding hopper, thus affecting the falling of the powder. Utility Model Content

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0017] Please see Figure 1-5 The feeding bin with a split partition mechanism includes two symmetrically arranged outer frames 2 installed outside the feeding bin 1. The outer frames 2 are combined to enclose the feeding bin 1. The two outer frames 2 are rotatably installed with a rotating shaft 32 inside each of them. A baffle 36 for closing the bottom of the feeding bin 1 is fixedly installed on the rotating shaft 32. A sliding rod 34 is installed on one end of the rotating shaft 32 located outside the outer frame 2, and a counterweight 35 is slidably installed on the sliding rod 34. During the feeding process, as the material enters the feeding hopper 1, the baffle 36 will be tightly fitted to the bottom opening of the feeding hopper 1 due to the presence of the counterweight 35. However, as the material accumulates on the baffle 36, the weight will continue to increase. When the total weight of the material exceeds the counterweight provided by the counterweight 35, the force balance is broken, and the baffle 36 will flip downwards. At this time, the baffle 36 will flip downwards to open the bottom opening of the feeding hopper 1, allowing the material to fall. The amount of material falling will be determined by the material in the feeding hopper 1. When the material from the previous stage is conveyed faster and accumulates in large quantities in the feeding hopper 1, the increased weight will cause the opening of the baffle 36 to be larger, allowing for a larger amount of material to fall. Conversely, if the material from the previous stage is conveyed slower, the weight of the material in the feeding hopper 1 will be lower, and the opening of the baffle 36 will be smaller. This allows the opening of the feeding hopper 1 to be adaptively controlled according to the actual amount of material inside, and prevents hot air from blowing into the feeding hopper 1 from affecting the falling of the material. The counterweight 35 is divided into two halves and is engaged with the slide bar 34. The two halves of the same counterweight 35 can be connected and locked to the slide bar 34 by screws, nuts, etc.
[0018] In another embodiment of this utility model: the opening of the feeding bin 1 is V-shaped, and the two baffles 36 are inclined and attached to the V-shaped opening surface of the feeding bin 1. The feeding hopper 1 is V-shaped, which also makes the downward tilt angle of the baffle 36 larger. Therefore, when the baffle 36 is slightly open, the material can fall more easily.
[0019] In another embodiment of this utility model: protrusions 2.1 are provided on both sides of the outer frame 2 to accommodate the baffle 36; The protrusions 2.1 on both sides of the outer frame 2 allow the baffles 36 to be set wider, thus better sealing the bottom opening of the feeding bin 1. At the same time, the protrusions 2.1 also limit the maximum rising height of the baffles 36, so that the two baffles 36 can evenly seal the bottom of the feeding bin 1.
[0020] In another embodiment of this utility model: a ring seat 31 is fixedly installed on the outer frame 2, a rotating shaft 32 is rotatably installed in the ring seat 31, and a connecting seat 33 is fixedly installed at the end of the rotating shaft 32, and a slide rod 34 is fixedly installed on the connecting seat 33. Each shaft 32 has a connecting seat 33 at both ends, and the connecting seat 33 can be divided into two halves. The slide rod 34 is installed on one half. The two halves of the connecting seat 33 are connected by screws to be locked onto the shaft 32, so as to facilitate the adjustment of the angle of the slide rod 34.
[0021] In another embodiment of this utility model: the baffle 36 is L-shaped, the short arm end of the baffle 36 is fixedly installed on the rotating shaft 32, and the short arm end of the baffle 36 coincides with the diameter of the rotating shaft 32 perpendicular to the inner wall of the air outlet duct 2.2; Among them, reference Figure 2 The upper end of the outer frame 2 is provided with an air outlet 2.2 facing outward.
[0022] Among them, reference Figure 4 The circular projection of the cross-section of the rotating shaft 32 has several diameters. Figure 4 The central dotted line is the diameter of the pivot 32 perpendicular to the inner wall of the air outlet 2.2, and the top of the short arm end of the baffle 36 coincides with the diameter of the dotted line, so that the baffle 36 will not come into contact with the feeding bin 1 when it rotates downward. The baffle 36 is L-shaped so that when its right-angle end rotates upward under the action of the counterweight 35, it can abut against the upper inner wall of the air outlet 2.2, thereby sealing the gap in the upper half of the air outlet 2.2 located on the rotating shaft 32, and further preventing the influence of external airflow or foreign objects on the interior of the feeding bin 1.
[0023] In another embodiment of this utility model: a stud 8 is fixedly installed on the outer frame 2, and a protruding plate 7 is sleeved on the stud 8, and a cover plate 6 is fixedly installed on the protruding plate 7; The cover plate 6 can be installed above the air outlet 2.2 by the cooperation of the stud 8 and the nut, thereby partially blocking the air outlet 2.2 without closing it off. If the nut is placed on the stud 8 part between the cover plate 6 and the outer frame 2, the cover plate 6 can be raised to avoid closing the air outlet 2.2. The rotating shaft 32 passes through the air outlet 2.2 of the outer frame 2. It occupies part of the space of the air outlet 2.2, but does not completely block the air outlet 2.2. Therefore, when hot air blows up from the bottom, the inclined baffle 36 can guide some of the hot air out of the air outlet 2.2, which can reduce the impact on the material falling from the unloading bin 1.
[0024] In another embodiment of the present invention, a duct pipe 41 is further included, and a diversion pipe 42 is fixedly installed at the bottom end of each duct pipe 41. The rotating shaft 32 is hollow along its axial direction, and two branch pipes 42 are respectively inserted into the interior of the two rotating shafts 32 for gas supply; Cooling air can be introduced into the air duct 41 and then introduced into the two rotating shafts 32 through the split pipe 42, and blown out from the other end of the rotating shaft 32. The cooling air can cool the rotating shaft 32 and prevent it from getting stuck in the ring seat 31 and the outer frame 2 due to thermal expansion.
[0025] In another embodiment of this utility model: a switch valve 43 is installed on the air duct 41; The air outlet of the air duct 41 can be controlled by the switching valve 43; The top of the unloading hopper 1 is equipped with a feeding pipe 5 to connect with the previous conveying mechanism.
[0026] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
