Description

Technical Field

[0001] This utility model relates to the field of carbon product manufacturing technology, and in particular to a conduit-type feeding device. Background Technology

[0002] The powder used in isostatic graphite production consists of particles with significant differences in size, with a D50 typically maintained at 20~40μm and the largest particles reaching 300~500μm. It also contains ultrafine powder finer than 1μm. This complex particle size distribution characteristic can easily lead to a series of quality problems under the existing feeding method.

[0003] In the operation of existing feeding devices such as ton bags, mobile material boxes, and fixed material bins, the pressed powder needs to be transported from the storage container to the mold barrel. There is a significant height difference in this process, and the difference in air resistance between coarse and fine particles is extremely large: coarse particles, due to their larger mass and less air resistance, fall faster and can quickly settle at the bottom of the mold barrel or near the feeding point; fine powder, due to its lighter mass and higher proportion of air resistance, is easily suspended in the air during the fall, and after being dispersed by the airflow, it gathers at the edge of the mold barrel or in local areas, directly causing the initial uneven distribution of pressed powder in the mold barrel, forming a local difference of "coarse particles concentrated and fine powder piled up";

[0004] More importantly, there is a significant difference in the angle of repose between coarse and fine particles in the pressed powder: coarse particles have good flowability and easily slide naturally outwards along the accumulation surface after falling into the mold barrel, forming a relatively gentle accumulation pattern; fine powder, on the other hand, has strong inter-particle adhesion and poor flowability, making it difficult to diffuse after falling in, and easily forming steep local accumulations. This difference further exacerbates the segregation of coarse and fine particles—coarse particles continuously diffuse towards the edge of the mold barrel, while fine powder continues to accumulate in the center or near the feeding point, ultimately leading to severe particle grading in the pressed powder within the mold barrel and a significant decrease in the uniformity of the filling. Utility Model Content

[0005] The purpose of this invention is to provide a conduit-type feeding device, which solves the above-mentioned problems.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a conduit-type feeding device, including a mold barrel, a buffer chamber and a movable conduit, wherein the mold barrel is provided with a buffer chamber inside, a support frame is fixed on the outer side wall of the buffer chamber, a material distribution baffle is provided inside the mold barrel, a feeding cone is provided at the bottom of the mold barrel, and a movable conduit is provided at the bottom of the feeding cone.

[0007] Preferably, vibrators are installed on both sides of the mold barrel, and the vibrators are symmetrical on both sides of the mold barrel.

[0008] Preferably, the top of the mold barrel is provided with a lifting lug, and the top of the inside of the mold barrel is provided with a screen, which is located on top of the material distribution baffle.

[0009] Preferably, three material distribution baffles are provided, and the three material distribution baffles are evenly distributed inside the mold barrel.

[0010] Preferably, the number of discharge cones is the same as the number of movable guide tubes, and the discharge cones are evenly distributed at the bottom of the buffer chamber.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model provides a guide tube-type feeding device. Through the bending function of the movable guide tube, the operator can adjust the bending angle and direction of the guide tube according to actual needs, allowing the powder to fall to any designated position within the mold barrel. Simultaneously, combined with the non-fixed nature of the device, the buffer chamber can be lifted by the lifting lugs, flexibly adjusting the feeding position height. The combination of these two features can optimize the feeding plan in real time based on the accumulation pattern of the powder, ensuring uniform distribution of powder within the mold barrel, avoiding excessively thick or thin local accumulation, and improving the quality stability of the final molded product.

[0013] 2. This utility model provides a duct-type feeding device that guides powder towards the outlet through the conical structure of the feeding cone, ensuring that the powder in the buffer bin can be completely discharged without any residue accumulation. This not only improves the utilization rate of powder and avoids raw material waste, but also reduces the workload of subsequent cleaning devices and lowers the risk of contamination caused by residual powder deterioration during the next feeding.

[0014] 3. The present invention provides a conduit-type feeding device that removes larger particles and impurities from the powder by screening with a screen, thus ensuring the quality of the powder from the source. At the same time, the distribution baffle can perform preliminary dispersion treatment on the powder entering the device, avoiding the powder from clumping in the initial state, laying the foundation for uniform feeding in the later stage, and effectively reducing problems such as uneven feeding and inconsistent material quality in the mold barrel caused by powder impurities or clumping.

[0015] The device generates continuous vibration force through a vibrator, which can effectively break the accumulation balance of powder during the falling process. This prevents the powder from adhering to the inner wall of the device and blocking the feeding channel due to its own stickiness or static electricity, ensuring that the powder always falls smoothly, guaranteeing the continuity of the feeding process, and avoiding production interruptions caused by powder accumulation.

[0020] Combination Figure 1 As shown, the present invention provides a conduit-type feeding device, which includes a mold barrel 1, a buffer chamber 2 and a movable conduit 9. The buffer chamber 2 is provided inside the mold barrel 1, and a support frame 4 is fixed to the outer wall of the buffer chamber 2. A material distribution baffle 7 is provided inside the mold barrel 1, and a feeding cone 8 is provided at the bottom of the mold barrel 1. A movable conduit 9 is provided at the bottom of the feeding cone 8.

[0021] Vibrators 3 are installed on both sides of the mold barrel 1, and the vibrators 3 are symmetrical on both sides of the mold barrel 1.

[0022] The top of the mold barrel 1 is provided with a lifting lug 5, and the top of the inside of the mold barrel 1 is provided with a screen 6, which is located on the top of the material distribution baffle 7.

[0023] There are three material distribution baffles 7, which are evenly distributed inside the mold barrel 1.

[0024] The number of discharge cones 8 and movable guide tubes 9 is the same, and the discharge cones 8 are evenly distributed at the bottom of the buffer chamber 2.

[0025] Specifically,

[0026] The volume of mold barrel 1 is 0.2~5m³;

[0027] The buffer chamber 2 is made of metal, with a plate thickness of 0.5~5mm, a height of 20~100cm, and a volume of 0.2~3m³.

[0028] The material distribution baffle 7 is made of metal or other materials, with a taper of no less than 60 degrees to prevent powder accumulation. It has multiple material distribution baffles 7, which are movable and detachable.

[0029] Vibrator 3 uses air-source vibration or motor vibration, with 2 to 8 units arranged symmetrically;

[0030] The mesh size of the screen 6 is 75 mesh to 10 mm, and it is made of stainless steel screen 6 or stamped plate;

[0031] The cone angle of the discharge cone 8 is not less than 60 degrees to ensure that the powder does not accumulate. The discharge cones 8 are aligned with each other to ensure that the powder in the final buffer bin 2 can be discharged completely.

[0032] The movable conduit 9 is made of metal or plastic, can be bent at will, and has a length of 20~200cm and a diameter of 5~30cm.

[0033] Furthermore,

[0034] The crane lifts the lifting lug 5 of the buffer bin 2 and hoists it into the mold barrel 1, so that the support frame 4 of the mixing device rests on the mold barrel 1. The buffer bin 2 is equipped with a screen 6, which can disperse the powder and remove larger impurities. The powder is poured into the buffer bin 2 and is initially dispersed under the action of the distribution baffle 7. The vibrator 3 is started, so that the powder falls down to the discharge cone 8 under the drive of the vibration force, and then falls into the mold barrel 1 through the movable guide tube 9. The movable guide tube 9 can be manually bent so that the powder in the buffer bin 2 can fall to any position in the mold barrel 1.

[0035] Adjust the bending position of the movable guide tube 9 according to the stacking pattern of the powder to make the powder evenly distributed; the mixing device can be lifted by the lifting lug 5 to move the discharge position upward.
