Description

Technical Field

[0001] The utility model relates to the field of material feeding, in particular to a double-helix material uniformity device. Background Art

[0002] As the world's dependence on fossil fuels deepens, environmental and energy security issues are becoming increasingly prominent. This has prompted people to seek alternative fuel technologies to reduce dependence on traditional energy, reduce carbon emissions, and achieve sustainable energy development. To this end, the use of alternative fuels instead of coal in cement companies to reduce carbon emissions has become an urgent transformation measure to be implemented.

[0003] In recent years, the application of lightweight and flammable alternative fuels in cement kilns has been increasing. Currently, the most widely used alternative fuels are mainly lightweight alternative fuels such as waste textiles, waste plastics, and packaging bags. In alternative fuel technology, alternative fuels eventually need to enter the kiln system for combustion. In order to avoid the adverse effects of moisture contained in the alternative fuel on the kiln system, the alternative fuel needs to be dried before entering the kiln. However, at present, a large number of lightweight alternative fuels are prone to entanglement or agglomeration during transportation. Therefore, the alternative fuels entering the drying process often have unsatisfactory drying effects due to uneven distribution or accumulation and entanglement. Utility Model Content

[0031] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0032] In the present utility model, unless otherwise stated, directional words contained in terms such as "length direction, inside, upper, lower, below, adjacent", etc. merely represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0033] See also Figure 1-4 A double-helix material homogenizing device, comprising a driving device and a plurality of spiral reamers 1 arranged side by side, wherein the rotation directions of two adjacent spiral reamers 1 are opposite and they grind against each other, and the driving device drives the plurality of spiral reamers 1 to rotate synchronously;

[0034] The double-screw material uniformity device is provided with a feed port on the top and a discharge port on the bottom, and the feed port is provided along the length direction of the spiral reamer 1;

[0035] When the feed port is arranged at the middle position of the spiral reamer 1, the spiral reamer 1 is provided with a left-handed spiral blade 11 and a right-handed spiral blade 12, and the connection between the left-handed spiral blade 11 and the right-handed spiral blade 12 is located below the feed port.

[0036] Through the implementation of the above technical solution, multiple spiral reamers 1 arranged side by side can squeeze the materials located therein through their spiral blades, and realize the conveying of materials as the spiral reamers 1 rotate. The rotation directions of two adjacent spiral reamers 1 are opposite, and they roll against each other. Through the rolling action between the two adjacent spiral reamers 1, the agglomerated materials can be broken up. Moreover, the gap between the two spiral reamers 1 that roll against each other is fixed, so the amount of materials that can pass through is also relatively fixed, so the purpose of homogenizing the materials can be achieved, making the material feeding more uniform, which is conducive to the reliable drying of the materials.

[0037] When the feed ports are arranged at both ends of the spiral reamer 1, the material enters the double spiral material homogenizing device from the feed ports, and is transported forward along the conveying direction of the spiral reamer 1, and falls from the discharge port when passing through the discharge port.

[0038] When the feed port is set at the middle of the spiral reamer 1, after the material enters the double-helix material uniformity device, it will be pushed by the left-handed spiral blades 11 and right-handed spiral blades 12 on both sides of the position, which are respectively set to be left-handed and right-handed, and move toward the two ends of the spiral reamer 1, and fall at the discharge port during the movement.

[0039] Multiple spiral reamers 1 can be arranged side by side in the double spiral material uniformity device, and two adjacent spiral reamers 1 can form a set of mutually coordinated material feeding structures, and multiple spiral reamers 1 can form multiple sets of mutually coordinated material feeding structures by cooperating with each other. It is used in an environment with multiple material feeding points.

[0040] By using the multiple groups of mutually coordinated material discharge structures, multiple discharge ports can be obtained. By coordinating the conveying structure below the discharge ports, the purpose of evenly distributing the materials on the conveying structure below can be achieved. The materials discharged from the rear discharge port fall onto the conveying structure. As the conveying structure is transported forward, the materials evenly distributed on the conveying structure will be covered with new materials when passing through the adjacent discharge port in front, and so on. Therefore, the use of the double-helix material uniformity device with multiple spiral reamers 1 can improve the material discharge efficiency while achieving the effect of layered stacking of materials, so that the materials that fall into the conveying structure first will be pre-dried and will not easily stick to the materials that fall in later.

[0041] In this embodiment, preferably, the double-helix material homogenizing device further comprises a housing 4, the spiral reamer 1 is disposed in the housing 4, and both ends of the spiral reamer 1 are detachably connected to the housing 4;

[0042] The feed port is connected to the upper portion of the shell 4 , and the discharge port is connected to the lower portion of the shell 4 .

[0043] Under the action of the shell 4, the space between the two mutually grinding spiral reamers 1 whose two ends are fixedly connected to the shell 4 is fixed. Therefore, the purpose of uniform material feeding at the bottom can be achieved during the rotation of the spiral reamers 1.

[0044] In order to facilitate maintenance and replacement of the spiral reamer 1 , the spiral reamer 1 can be detachably connected to the housing.

[0045] In this embodiment, preferably, the plurality of spiral reamers 1 include a driving spiral reamer 5 and one or more driven spiral reamers 6 with adjustable spacing between the driving spiral reamer 5 .

[0046] When it is necessary to adjust the feeding efficiency of the double-screw material uniforming device, it can be achieved by adjusting the rotation speed of the spiral reamer 1. When it is necessary to improve the feeding efficiency, the rotation speed of the spiral reamer 1 can be increased. When it is necessary to reduce the feeding efficiency, the rotation speed of the spiral reamer 1 can be reduced. In addition, it can also be achieved by adjusting the spacing between the two spiral reamers 1 that cooperate with each other. When it is necessary to increase the feeding amount, the spacing between the two spiral reamers 1 that cooperate with each other can be increased by moving the driven spiral reamer 6 to increase the space between the two spiral reamers 1, thereby improving the feeding efficiency. When it is necessary to reduce the feeding amount, the spacing between the two spiral reamers 1 that cooperate with each other can be reduced by moving the driven spiral reamer 6 to reduce the space between the two spiral reamers 1, thereby reducing the feeding efficiency.

[0047] Multiple spiral reamers 1 are matched in pairs to form a set of blanking structure. If the distance between two spiral reamers 1 in the set of blanking structure needs to be adjusted, it can be achieved by adjusting the position of the driven spiral reamer 6 in the set.

[0048] In this embodiment, preferably, the driving device includes a driving mechanism 21 and a transmission mechanism 22, and the transmission mechanism 22 is configured as a chain drive;

[0049] The active spiral reamer 5 is connected to the driving mechanism 21 , and the driven spiral reamer 6 is connected to the driving mechanism 21 via a transmission mechanism 22 .

[0050] Preferably, both ends of the housing 4 are provided with horizontal through holes, through which the spiral reamer 1 passes to be fixedly connected to the housing 4. The driven spiral reamer 6 can move along the horizontal through holes to approach or move away from the active spiral reamer 5.

[0051] In one embodiment, both ends of the driven spiral reamer 6 are rotatably connected with an adjusting screw, which is horizontally arranged and cooperates with an adjusting nut fixedly arranged on the housing 4. The relative position of the driven spiral reamer 6 and the housing 4 can be adjusted by rotating the adjusting screw.

[0052] In another embodiment, a plurality of mounting holes are provided on the housing 4 , and the driven spiral reamer 6 can adjust its relative position with the housing 4 by cooperating with different mounting holes.

[0053] The transmission mechanism 22 is configured as a chain transmission, and the length of the chain 7 is slightly longer, so that the chain 7 will not be tensioned during use. When the driven spiral reamer 6 needs to move far away, the transmission mechanism 22 has the ability to move synchronously.

[0054] In this embodiment, preferably, the discharge port is arranged along the length direction of the spiral reamer 1 .

[0055] The discharge port is arranged along the length direction of the spiral reamer 1 , so that the double-spiral material uniformity device can discharge materials uniformly along the entire length direction of the spiral reamer 1 .

[0056] Preferably, the length of the discharge port is set to match the length of the conveying structure located below the discharge port, so as to achieve the purpose of uniform material discharge on the entire conveying structure, which is more conducive to improving the drying efficiency of the material.

[0057] When multiple spiral reamers 1 are provided in the double-helix material uniformity device, multiple discharge ports can be obtained corresponding to different material discharging structures. By cooperating with a conveying structure below the discharge port, the purpose of evenly distributing the material on the conveying structure below can be achieved. The material discharged from the rear discharge port falls onto the conveying structure. As the conveying structure is conveyed forward, when the material evenly distributed on the conveying structure passes through the adjacent discharge port located in the front, new material will cover the original material, and so on. Therefore, the use of the double-helix material uniformity device with multiple spiral reamers 1 can achieve the effect of layering and stacking materials while improving the material discharging efficiency, so that the material that falls into the conveying structure first can be pre-dried, which improves the material drying efficiency, and also makes it less likely that the material that falls in first and the material that falls in later will stick to each other.

[0058] In this embodiment, preferably, a plurality of feed ports are provided.

[0059] In this embodiment, preferably, a plurality of feed ports are provided corresponding to the same spiral reamer 1 .

[0060] Multiple discharge ports can also be set on the same set of discharge structures. These discharge ports are usually not set at the ends of the spiral reamer 1. Corresponding to the positions of these discharge ports, left-handed spiral blades 11 and right-handed spiral blades 12 are set at these positions on the spiral reamer 1 to push the material falling from the discharge port to both sides and then fall from the discharge port located at the lower part of the shell 4.

[0061] It should be noted that the discharge ports on the same spiral reamer 1 need to be as far apart as possible so that the materials entering from the two feed ports will not meet in the shell 4 and can be discharged in time through the discharge port to avoid the situation where the materials between the two adjacent feed ports accumulate in the shell 4 due to different movement directions and cause blockage.

[0062] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0064] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
