Description

Technical Field

[0001] The present invention relates to the field of powder feeding and conveying, and more particularly to a cyclone disturbance type feeder. Background Art

[0002] In the fields of battery material preparation, pharmaceutical manufacturing, and food processing, material feeding and transportation have always been crucial. A good feeding system determines the efficiency of subsequent production and manufacturing. Therefore, improving the efficiency of feeding systems and developing feeding technologies have always been important aspects of industrial technological progress.

[0003] Using airflow for feeding has always been one of the common feeding methods in the field of powder materials, and the application of Venturi tubes is also very common. However, current feeding equipment still has some defects, such as: (1) when feeding from a silo, the material is discharged only by its own weight, which easily leads to material accumulation at the discharge point, causing blockage and affecting the feeding rate; (2) in the discharge pipe, the discharge efficiency is low due to the influence of airflow flat flow; (3) in the mixed flow feeding chamber, due to the change in flow state, the material is easily deposited, which can block the pipe.

[0004] Therefore, under the current situation, it is very necessary to provide a cyclone disturbance feeder that can solve the above-mentioned defects of the prior art. Summary of the Invention

[0005] In view of this, the present invention proposes a cyclone disturbance feeder, and its specific technical solution is as follows:

[0006] A cyclone disturbance feeder, comprising a silo, a discharge pipe, a feeding circular pipe 1, a swirl generating pipe, a discharge control valve, a venturi feeding pipe, a suspension flow pipe, and a feed circular pipe 2; the bottom discharge port of the silo is connected to the upper end of the discharge pipe, and the discharge control valve is installed at the corresponding connection between the two, and an air supply valve is installed on the upper part of the silo; the feed circular pipe 1 is connected to the inlet in front of the venturi feeding pipe, and the feed circular pipe 2 is connected to the outlet at the rear of the venturi feeding pipe; the lower end of the discharge pipe is connected to the feed circular pipe 1, and the discharge pipe and the feed circular pipe 1 are connected. An inclination angle is formed between them, and the feed port at the lower end of the discharge pipe points to the inlet of the Venturi feeding pipe; the swirl generating tube is installed in front of the feed port and is connected to the feeding circular tube one; an inclination angle is formed between the swirl generating tube and the feeding circular tube one, and the outlet of the swirl generating tube connected to the feeding circular tube one points to the feed port, and the suspended flow tube is connected to the feeding circular tube two; an inclination angle is formed between the suspended flow tube and the feeding circular tube two, and the outlet of the suspended flow tube connected to the feeding circular tube two points to the flow direction of the material.

[0007] Preferably, the swirl generating tube is connected to the bottom of the feeding circular tube, and air flow is introduced into the bottom inlet of the swirl generating tube. The air flow ejected from the swirl generating tube forms a clockwise swirl in the discharge pipe from a top-down perspective, which can disturb the material accumulated in the discharge pipe. The speed of the air flow introduced into the bottom inlet of the swirl generating tube is 8m / s-25m / s.

[0008] Preferably, an air flow is introduced into the front end inlet of the feeding circular tube 1, which can blow up the passing material to form a gas-solid suspension flow. The Venturi feeding tube can effectively accelerate the feeding, and the speed of the air flow introduced into the front end inlet of the feeding circular tube 1 is 12m / s-40m / s.

[0009] Preferably, the suspension flow tube is connected to the bottom of the feeding circular tube 2, and air flow is introduced into the bottom inlet of the suspension flow tube. The air flow ejected from the suspension flow tube can blow up the deposited materials and inhibit the suspension flow materials from settling and clogging the tube. The speed of the air flow introduced into the bottom inlet of the suspension flow tube is 12m / s-40m / s.

[0010] Preferably, the diameters of the discharge pipe, the first feeding circular pipe, and the second feeding circular pipe are 30 mm to 150 mm, and the diameters of the swirl generating pipe and the suspension flow pipe are 10 mm to 50 mm.

[0011] Preferably, the inclination angle formed between the discharge pipe and the feeding circular tube 1 is between 15°-60°; the inclination angle formed between the vortex generating tube and the feeding circular tube 1 is between 30°-60°; the inclination angle formed between the suspension flow tube and the feeding circular tube 2 is between 15°-30°.

[0012] Preferably, the silo and each pipeline are made of non-metallic materials or metal outer layer non-metallic lining materials; the non-metallic materials include: polytetrafluoroethylene, polycarbonate, polyamide, polyacetal, polypropylene, polyphenylene sulfide, polyarylate, unsaturated polyester, phenolic plastic, epoxy plastic, ultra-high molecular weight polyethylene, modified polyphenylene ether, and ceramics; the non-metallic lining materials in the metal outer layer non-metallic lining materials include: polytetrafluoroethylene, polycarbonate, polyamide, polyacetal, modified polyphenylene ether, polyester, phenolic plastic, epoxy plastic, and ultra-high molecular weight polyethylene, and the lining thickness is 3mm to 15mm.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. A swirl generating tube is provided in front of the feed port, through which a clockwise swirl is formed in the discharge pipe from a top-down perspective, stirring the material deposited in the discharge pipe and accelerating the falling of the material.

[0015] 2. By setting a Venturi feeding pipe behind the feed port and utilizing the principle of negative pressure suction, the flow of materials is accelerated, while forming a strong turbulence effect, reducing the impact of horizontal flow and increasing the feeding rate.

[0016] 3. A suspension flow pipe is set behind the Venturi feeding pipe to ensure that the material in the mixed flow feeding chamber can form a gas-solid suspension flow and discharge quickly, reducing the accumulation of materials in the mixed flow feeding chamber due to changes in flow state and improving feeding efficiency.

[0017] 4. The parts of each component that come into contact with the material are made of non-metallic materials or metal-lined non-metallic materials, which can effectively prevent metal contact from contaminating the material. BRIEF DESCRIPTION OF THE DRAWINGS

Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0025] Example:

[0026] like Figure 1 、 Figure 2 As shown, the present invention is a cyclone disturbance feeder, including a silo 1, an air supply valve 2, a discharge pipe 3, a feeding circular pipe 4, a swirl generating pipe 5, a discharge control valve 6, a Venturi feeding pipe 7, a suspension flow pipe 8, and a feeding circular pipe 9.

[0027] The diameters of the feeding pipe 3, the feeding circular pipe 1 4 and the feeding circular pipe 2 9 are 30mm-150mm, and the diameters of the swirl generating pipe 5 and the suspension flow pipe 8 are 10mm-50mm.

[0028] The bottom discharge port of the silo 1 is connected to the upper end of the discharge pipe 3, and a discharge control valve 6 is installed at the corresponding connection between the two.

[0029] An air supply valve 2 is installed on the upper part of the silo 1 to keep the air pressure inside the silo 1 stable.

[0030] Feeding tube 1 (4) connects to the front inlet of Venturi feeding tube 7, while feeding tube 2 (9) connects to the rear outlet of Venturi feeding tube 7. The pipeline formed by feeding tube 1 (4), Venturi feeding tube 7, and feeding tube 2 (9) is installed horizontally below the discharge pipe 3. Negative pressure is created in front and behind the Venturi feeding tube 7, accelerating material transportation.

[0031] The lower end of the discharge pipe 3 is connected to the feeding circular pipe 1 4, and an inclination angle is formed between the discharge pipe 3 and the feeding circular pipe 1 4, which is between 15° and 60°, so that the material can fall from the silo 1 by its own weight, and the feed port at the lower end of the discharge pipe 3 points to the inlet of the Venturi feeding pipe 7.

[0032] A swirl tube 5 is installed in front of the feed port and connected to the bottom of the feed tube 1 (4). The two tubes are tilted at an angle between 30° and 60°, with the outlet at the junction pointing toward the feed port. Air flows into the bottom inlet of the swirl tube 5 at a velocity of 8 to 25 m / s. The airflow from the swirl tube 5 creates a clockwise vortex in the discharge pipe 3 from a top-down perspective, disturbing the accumulated material and accelerating its descent.

[0033] An air flow is introduced into the front end entrance of the feeding circular tube 4, and the air flow speed is 12m / s-40m / s, which can blow up the passing material to form a gas-solid suspension flow, and the Venturi feeding tube 7 can effectively accelerate the feeding.

[0034] Suspension flow tube 8 is connected to the bottom of feed tube 2 9 ; there's an inclination angle between 15° and 30° between them, with the outlet at the connection oriented in the direction of material flow. Airflow enters the bottom inlet of suspension flow tube 8 at a velocity of 12m / s to 40m / s. This airflow displaces deposited material, preventing it from settling and potentially clogging the tube.

[0035] The silos and pipelines are made of non-metallic materials or metal outer layer and non-metallic inner lining materials.

[0036] Specifically, non-metallic materials include but are not limited to: polytetrafluoroethylene (PTFE), polycarbonate (PC), polyamide (nylon), polyacetal (POM), polypropylene (PP), polyphenylene sulfide (PPS), polyarylate, unsaturated polyester, phenolic plastic, epoxy plastic, ultra-high molecular polyethylene (UPE), modified polyphenylene ether (modified PPE), ceramics, etc., among which polytetrafluoroethylene (PTFE), modified polyphenylene ether (modified PPE), epoxy plastic, ultra-high molecular polyethylene (UPE), and ceramics are preferred.

[0037] The metal outer layer of the non-metallic lining material is generally coated with carbon steel or stainless steel. The non-metallic lining materials include but are not limited to: polytetrafluoroethylene (PTFE), polycarbonate (PC), polyamide (nylon), polyacetal (POM), modified polyphenylene ether (modified PPE), polyester (PETP, PBTP), phenolic plastic, epoxy plastic, ultra-high molecular polyethylene (UPE), etc., preferably polytetrafluoroethylene (PTFE), and the lining thickness is 5mm to 15mm.

[0038] When the cyclone disturbance feeder of the present invention is working, air flow is first introduced from the feeding circular pipe 1 4, and negative pressure is formed at the venturi feeding pipe 7; air flow is introduced into the swirl generating pipe 5, and a swirl is formed at the feeding pipe 3; air flow is also introduced into the suspension flow pipe 8;

[0039] Then open the discharge control valve 6, and the material in the silo 1 begins to flow into the feeding circular pipe 1 4 through the discharge pipe 3. At this time, the material accumulated in the discharge pipe 3 is dispersed due to the swirl effect, and falls faster and falls between the feeding circular pipe 1 4 and the Venturi feeding pipe 7;

[0040] Due to the negative pressure formed at the Venturi feeding pipe 7, the material in front of the pipe begins to flow faster, avoiding the occurrence of accumulation;

[0041] The material flowing through the Venturi feeding pipe 7 forms a gas-solid suspension flow in the feeding circular pipe 2 9 under the action of the suspension flow pipe 8, thereby accelerating the feeding process.

[0042] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Reference can be made to the common and similar parts between the various embodiments. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the method description.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
