Description

Technical Field

[0001] This invention mainly relates to the field of tobacco production, and in particular to a novel dust removal pipeline tobacco shred recycling and conveying device. Background Technology

[0002] In the existing technology, the tobacco shred recovery and conveying device in the dust removal pipeline uses a motor to drive an impeller roller to convey short tobacco shreds, that is, the impeller roller rolls the short tobacco shreds into the recovery channel. Summary of the Invention

[0003] Using a motor-driven impeller roller to convey short tobacco shreds has the drawback of easily clogging the shreds, especially when restarting after a shutdown. To solve this problem, our R&D team, after in-depth research and experimentation, invented a new type of dust-collecting pipeline tobacco shred recovery and conveying device.

[0004] The present invention specifically adopts the following solution:

[0005] A novel dust-collecting pipeline tobacco shred recovery and conveying device is disclosed. The device mainly includes a collector, a storage cylinder, a discharge hopper, a negative pressure generator, and a discharge pipeline, which are connected in series. It also includes a make-up air device connected in parallel to the discharge hopper. The novel dust-collecting pipeline tobacco shred recovery and conveying device is arranged between the outlet of the primary separation device and the inlet of the secondary separation device. The inlet of the primary separation device is drawn from the dust collection pipeline, and the outlet of the secondary separation device is introduced into the main tobacco shred conveying channel. The function of the dust removal pipeline is to remove dust from the tobacco shreds during the main channel conveying process. First, the primary separation device separates the dust, and in addition to the dust, reusable short tobacco shreds are also separated. The dust and short tobacco shreds pass sequentially through the collector, storage cylinder, discharge hopper, negative pressure generator, and discharge pipeline of the new dust removal pipeline tobacco shred recovery and conveying device, and finally enter the secondary separation device. In the secondary separation device, the dust and short tobacco shreds are completely separated, the short tobacco shreds are recycled and re-enter the main tobacco conveying channel, and the dust is collected and discharged. The function of the air supply device connected to the discharge hopper is to supply compressed air and regulate the compressed air through the air supply valve.

[0006] The storage cylinder is a hollow cuboid structure. The upper part is connected to the outlet of the collector that collects short tobacco shreds in the first-stage separation device, and the lower part is connected to the dropping hopper. Both the upper and lower openings are rounded to prevent tobacco shreds from causing channel blockage. Its main function is to buffer a large amount of short tobacco shreds that flow in in a short period of time when an abnormal shutdown occurs.

[0007] The air supply device includes an air supply valve and a flange seat, which are connected in series. The head of the air supply valve has a ring of screw holes for adjusting the air supply volume. If a screw is used to block part of the screw holes, the air supply volume will be reduced accordingly. The outlet of the flange seat is connected to the discharge hopper.

[0008] The negative pressure generator includes an inlet flange, a generator body, a sealing ring, a generator inlet seat, and an outlet flange, which are connected in series. The sealing ring is arranged between the generator body and the generator inlet seat. The generator body and the generator inlet seat are coaxially sleeved together, and the sleeve gap on the outlet side is 0.06mm. The generator inlet seat has an air inlet for external compressed air. The inlet flange is connected to the hopper, and the outlet flange is connected to the discharge pipe.

[0009] To ensure that the shredded tobacco separated by the primary separation unit is reliably transported to the secondary separation unit, this invention adds a negative pressure generator, which, in conjunction with the stable negative pressure provided by the system, assists in the transport of short tobacco shreds. The negative pressure generator utilizes the jet effect of compressed air to create a certain negative pressure at the end of the generator, while generating a larger positive pressure at the inlet end to transport the short tobacco shreds collected in the discharge hopper. Under the action of negative pressure, the short tobacco shreds are sent into the discharge pipe, which is connected to the downstream secondary separation unit.

[0010] Advantages of this invention:

[0011] 1. The device of the present invention does not require a motor drive, which can reduce the manufacturing cost of the equipment.

[0012] 2. The device of the present invention eliminates the impeller and brake roller, thereby eliminating the side effect of the brake roller further crushing the tobacco and eliminating the tobacco blockage problem at that point.

[0013] 3. The device of the present invention is equipped with a negative pressure generator to supplement the power for conveying short tobacco shreds and dust, ensuring continuous and stable conveying function and reliable operation. Attached Figure Description

[0021] like Figure 2 As shown, the overall external structure of the novel dust removal pipeline tobacco recycling and conveying device of the present invention is displayed from the side.

[0022] The collector 101, storage cylinder 102, and discharge hopper 103 are cut longitudinally.

[0023] like Figure 3 As shown, a cross-sectional view of the negative pressure generator of the present invention is presented along its longitudinal axis.

[0024] The negative pressure generator 104 includes an inlet flange 10401, a generator body 10402, a sealing ring 10403, a generator air inlet seat 10404, and an outlet flange 10405, which are connected in series. The sealing ring 10403 is arranged between the generator body 10402 and the generator air inlet seat 10404. The generator body 10402 and the generator air inlet seat 10404 are coaxially sleeved together, and the sleeve gap on the outlet side is 0.06mm. The generator air inlet seat 10404 has an air inlet for external compressed air. The inlet flange 10401 is connected to the hopper 103, and the outlet flange 10405 is connected to the discharge pipe 105.

[0025] Specific embodiments of the present invention are as follows:

[0026] Example 1: As Figure 1 , Figure 2 As shown, the present invention relates to a novel dust removal pipeline tobacco recycling and conveying device 1.

[0027] The novel dust removal pipeline tobacco recycling and conveying device 1 mainly includes a collector 101, a storage cylinder 102, a discharge hopper 103, a negative pressure generator 104, and a discharge pipeline 105, which are connected in series. It also includes a supplementary air device 106 connected in parallel to the discharge hopper 103.

[0028] The novel dust-removing pipeline tobacco shred recovery and conveying device 1 is arranged between the outlet of the primary separation device and the inlet of the secondary separation device. The inlet of the primary separation device is drawn from the dust-removing pipeline, and the outlet of the secondary separation device is introduced into the main tobacco shred conveying channel. The function of the dust-removing pipeline is to remove dust from the tobacco shreds during the conveying process in the main channel. First, the primary separation device completes the separation of dust, and in addition to dust, reusable short tobacco shreds are separated. The dust and short tobacco shreds pass sequentially through the collector 101, storage cylinder 102, drop hopper 103, negative pressure generator 104, and discharge pipeline 105 of the novel dust-removing pipeline tobacco shred recovery and conveying device 1, and finally enter the secondary separation device. In the secondary separation device, the dust and short tobacco shreds are completely separated, the short tobacco shreds are recycled and re-enter the main tobacco shred conveying channel, and the dust is collected and discharged. The function of the air supply device 106 connected to the drop hopper 103 is to connect compressed air and to regulate the compressed air through the air supply valve 10601.

[0029] The storage cylinder 102 is a hollow cuboid structure. The upper part is connected to the discharge port of the collector 101 that collects short tobacco shreds and is connected to the primary separation device. The lower part is connected to the dropping hopper 103. Both the upper and lower openings are rounded to prevent tobacco shreds from causing channel blockage. Its main function is to buffer a large amount of short tobacco shreds that flow in in a short period of time when an abnormal shutdown occurs.

[0030] The air supply device 106 includes an air supply valve 10601 and a flange seat 10602 connected in series. The head of the air supply valve 10601 has a ring of screw holes for adjusting the air supply volume. When a screw is used to block part of the screw holes, the air supply volume is reduced accordingly. The outlet of the flange seat 10602 is connected to the discharge hopper 103.

[0031] To ensure that the shredded tobacco separated by the primary separation unit is reliably transported to the secondary separation unit, the present invention adds a negative pressure generator 104, which, in conjunction with the stable negative pressure provided by the system, assists in the transport of short tobacco shreds. The negative pressure generator 104 utilizes the jet effect of compressed air to create a certain negative pressure at the end of the generator, while generating a larger positive pressure at the inlet end to transport the short tobacco shreds collected in the discharge hopper. Under the action of negative pressure, the short tobacco shreds are sent into the discharge pipe, which is connected to the downstream secondary separation unit.

[0032] The device of the present invention does not require a motor drive and eliminates the impeller and brake roller, which can eliminate the side effect of the brake roller crushing the tobacco again and can basically eliminate the occurrence of tobacco blockage at this point. The device of the present invention is equipped with a negative pressure generator 104 to supplement the power for conveying short tobacco and dust, ensuring that the conveying function is continuous, stable and reliable.
