Description

Technical Field

[0001] This utility model relates to the field of powder collector technology, specifically a novel adjustable powder collector. Background Technology

[0002] Existing cyclone dust collectors typically employ a fixed return air duct structure. The basic principle is that dust-laden gas enters the main duct of the dust collector tangentially, and the larger particles are thrown against the inner wall of the duct by the centrifugal force of rotation and then fall down, exiting through the bottom discharge port; while smaller particles are carried upward from the central return air duct by the airflow and discharged through the discharge port.

[0003] However, due to differences in particle size, specific gravity, and feed air velocity among different materials, a fixed-structure return air duct can easily lead to excessive fine powder entering the return air pipe, affecting powder recovery rate and reducing output. Especially when flexible adjustment of product particle distribution is required, a fixed structure is no longer suitable for actual needs.

[0004] Based on this, the present invention designs a novel adjustable powder collector to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a novel adjustable dust collector to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a novel adjustable powder collector, comprising: a main body of the powder collector; a discharge section is detachably connected to the top of the main body of the powder collector, and a main return air duct is fixedly connected to the inner wall of the main body of the powder collector, wherein the bottom end of the discharge section and the top end of the main return air duct are interconnected. A fixing nut is fixedly connected to the top of the discharge section. A screw rod is internally threaded into the fixing nut. One end of the screw rod extends into the main barrel of the powder collector and is fixedly connected to a fixing rod. A secondary return air barrel is fixedly connected to the outer end of the fixing rod. The secondary return air barrel is slidably fitted inside the main return air barrel, and the fixing rod can drive the secondary return air barrel to move up and down inside the main return air barrel.

[0007] Preferably, the end of the lead screw extending from the fixing nut is threaded with a locking nut for stabilizing the lead screw and assisting in adjustment.

[0008] Preferably, the main body of the powder collector has a feed inlet, which is connected to the internal space of the main body of the powder collector.

[0009] Preferably, one end of the discharge section has a discharge port that communicates with the inside of the main barrel of the powder collector.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This utility model provides a technical solution: a novel adjustable powder collector, comprising: a powder collector main barrel 1; a discharge part 3 is detachably connected to the top of the powder collector main barrel 1, and a main return air barrel 4 is fixedly connected to the inner wall of the powder collector main barrel 1, with the bottom end of the discharge part 3 and the top end of the main return air barrel 4 communicating with each other. The discharge section 3 and the main body 1 of the powder collector have matching screw holes and are locked and fixed to the main body 1 of the powder collector by bolts. They can be disassembled separately for auxiliary inspection and maintenance. The top of the discharge section 3 is fixedly connected to a fixing nut 5. The fixing nut 5 is internally threaded with a screw rod 6. One end of the screw rod 6 extends into the main body 1 of the powder collector and is fixedly connected to a fixing rod 7. The outer end of the fixing rod 7 is fixedly connected to a secondary return air hopper 8. The secondary return air hopper 8 is slidably fitted inside the main return air hopper 4, and the fixing rod 7 can drive the secondary return air hopper 8 to move up and down inside the main return air hopper 4. Utilizing the linear transmission principle driven by the screw thread 6, the screw 6 is rotated manually or automatically, driving the fixed rod 7 and the auxiliary return air duct 8 to move along the axis of the main return air duct 4. The fixed rod 7 is arranged in a cross shape to increase stability. By adjusting the position of the auxiliary return air duct 8, the length of the return air channel is changed, thereby affecting the airflow resistance and separation path. It can be adjusted without disassembling the equipment, making it convenient to operate, saving time, improving the system's collection efficiency and versatility, and enhancing its industrial adaptability.

[0017] More preferably, one end of the lead screw 6 extending from the fixing nut 5 is threadedly connected to a locking nut 9, which is used to stabilize the lead screw 6 and assist in adjustment; The upper end of the lead screw 6, extending out of the fixing nut 5, is equipped with a locking nut 9. The locking nut 9 is a commonly used mechanical limiting element that can fix the position after adjustment, so that the lead screw 6 is not easy to rotate on its own when subjected to vibration or wind pressure during use, thus enhancing positional stability.

[0018] More preferably, the main body 1 of the powder collector is provided with a feed inlet 2, which is connected to the internal space of the main body 1 of the powder collector. The feed inlet 2 is tangentially opened in the main body 1 of the dust collector, controlling the dust to enter the main body 1 of the dust collector in a tangential direction, and forming a rotating flow field in conjunction with the cyclone principle to generate centrifugal force to separate particles.

[0019] More preferably, one end of the discharge section 3 is provided with a discharge port that communicates with the interior of the main barrel 1 of the powder collector; After separation, the fine powder or gas enters the discharge section 3 through the main return air duct 4 and the auxiliary return air duct 8, and is discharged from the discharge port, connecting with downstream equipment such as dust collectors or return air pipes.

[0020] A further preferred embodiment has a discharge port 10 for material discharge at the bottom of the main body 1 of the powder collector; The coarse particles separated by centrifugation settle to the bottom due to gravity and are discharged from the discharge port 10, realizing the automatic discharge of solid powder after solid-gas separation.

[0021] A specific application of this embodiment is as follows: According to the material properties and grading requirements, the locking nut 9 is loosened and the rotating screw 6 is operated. The auxiliary return air bucket 8 is moved up and down in the main return air bucket 4 through the fixed rod 7 to adjust the height. After moving to the preset height, the locking nut 9 is tightened to position it. During operation, the powder-containing gas enters the main body 1 of the powder collector at high speed in a tangential direction through the feed inlet 2. The powder and the airflow form a rotating centrifugal motion in the main body. Larger particles fall into the discharge port 10, and finer powder is carried upward along the center by the airflow and enters the discharge section 3 through the auxiliary return air bucket 8 and the main return air bucket 4, and is discharged through the discharge port. If the powder grading is found to be too coarse, i.e. the fine powder recovery rate is low, the height of the secondary return air duct 8 can be adjusted and shortened to reduce resistance and increase the proportion of fine powder passing through. If the powder grading is too fine, i.e. too much fine powder enters the lower part, the length of the secondary return air duct 8 can be increased to enhance the return air resistance and make more fine powder settle. After each adjustment, the locking nut 9 can be locked in place.
