Description

Technical Field

[0001] This utility model belongs to the field of airlock technology, and in particular relates to an airlock that prevents blockage during unloading. Background Technology

[0002] Airlocks are used to ensure uniform and continuous material supply in conveying pipes, maintaining a stable gas-to-solid ratio, thus enabling the pneumatic conveying system to operate normally. When the airlock is installed at one end of the conveying pipe to control material flow, material often gets stuck on the inner wall of the rotating airlock rotor blades, obstructing material flow and affecting the material supply system. Furthermore, the supply system needs to be shut down before the airlock can be removed and repaired, significantly impacting the material supply process. In addition, when material enters the airlock rotor blades from the top, the airlock closes when the supply system is shut down, causing material to accumulate between the blades. Prolonged accumulation between the blades can lead to material deterioration, which can then be mixed into the newly conveyed material during the next feeding cycle.

[0003] To address this issue, we provide an airlock for preventing material blockage during unloading. Utility Model Content

[0004] The purpose of this invention is to provide an airlock for preventing material blockage during unloading. This is achieved by fixing a fixed shaft in the rotor frame assembly inside the outer cylinder, aligning the fixed shaft axis with the outer cylinder axis. A first rotor bushing is rotatably installed outside the fixed shaft. This causes a first sector-shaped rotating blade fixed outside the first rotor bushing to rotate inside the outer cylinder. Material conveyed from above the outer cylinder falls onto the first sector-shaped rotating blade. The rotation of the first sector-shaped rotating blade causes the material above to be swept downwards by a first sector-shaped baffle fixed outside the fixed shaft, completing a continuous and uniform feeding process while preventing material from jamming the blades. The material is disposed of by fixing a sweeping plate beam to the upper end of the arc-shaped vertical plate at one end of the first sector-shaped rotating blade, and installing a sweeping plate on the sweeping plate beam. When the first rotor shaft sleeve rotates, the sweeping plate on the sweeping plate beam sweeps the material off the first sector-shaped partition, preventing the material from accumulating on the sector-shaped partition. When the feeding system stops, the sweeping plate sweeps the material off the first sector-shaped partition onto the first sector-shaped rotating blade. When rotating, the first sector-shaped partition sweeps the material above the first sector-shaped rotating blade to complete the discharge, preventing the material from accumulating on the blade or the first sector-shaped partition.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an airlock for preventing blockage during unloading, comprising an outer cylinder, a rotor assembly, and a rotor frame assembly. The rotor assembly includes a first rotor bushing, and the rotor frame assembly includes a fixed shaft and a set of supporting beams. The fixed shaft is rotatably sleeved inside the outer cylinder, and the axis of the fixed shaft coincides with the axis of the outer cylinder. A set of supporting seats is circumferentially fixed on the inner wall of the outer cylinder, and a set of supporting beams is circumferentially fixed on the top of the fixed shaft. The lower end of the supporting beams away from the fixed shaft is fixedly installed on the upper end of each supporting seat. A set of first sector-shaped partitions is circumferentially fixed on the outer side of the fixed shaft, with a gap between the first sector-shaped partitions and the inner wall of the outer cylinder. The first rotor bushing is sleeved on the outer side of the fixed shaft at the lower end of the first sector-shaped partitions. A set of first sector-shaped blades is circumferentially fixed on the outer side of the first rotor bushing. The first rotor bushing is connected to the output shaft of the motor via a belt.

[0007] The present invention is further configured such that a pointed beam is fixedly installed above the receiving beam assembly, and the end of the pointed beam away from the receiving beam is pointed.

[0008] The present invention is further configured such that the end of the first sector-shaped rotating blade away from the first rotor bushing is an outer arc and the edge of the outer arc is attached to the inner wall of the outer cylinder, an arc-shaped vertical plate is fixed above the edge of the end of the first sector-shaped rotating blade away from the first rotor bushing, a sweeping plate beam is fixed at the upper end of the side plate of the arc-shaped vertical plate near the first rotor bushing, and the first sector-shaped partition is between the sweeping plate beam and the first sector-shaped rotating blade.

[0009] The present invention is further configured such that the end of the sweeping plate beam away from the arc-shaped vertical plate extends toward the axis of the fixed axis, and sweeping plates are installed on the sweeping plate beam.

[0010] The present invention is further configured such that sliding grooves are provided at both ends of the sweeping plate along the length direction of the sweeping plate, the sweeping plate beam is vertically slidably sleeved in the sliding groove, and a set of compression springs are fixedly installed in an array at the bottom of the sliding groove along the length direction of the sliding groove, and the upper end of the compression spring is fixedly connected to the lower end of the sweeping plate beam.

[0011] The present invention is further configured such that a set of second sector-shaped partitions is fixedly provided on the outer periphery of the first sector-shaped partition with a fixed axis, and the edge surface of the second sector-shaped partitions intersects with the edge surface of the first sector-shaped partition below.

[0012] The present invention is further configured such that a second rotor bushing is rotatably mounted on the outer periphery of the fixed axis at the lower end of the second sector-shaped partition, a set of second sector-shaped rotating blades are fixedly arranged in a circumferential array on the outer side of the second rotor bushing, a blade connecting arc plate is fixedly mounted below the second sector-shaped rotating blades, the outer arc surface of the blade connecting arc plate is in contact with the inner arc surface of the outer cylinder, and the lower end of the blade connecting arc plate is fixedly connected to the upper end of the arc-shaped vertical plate.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model fixes the fixed shaft in the rotor frame assembly inside the outer cylinder and makes the axis of the fixed shaft coincide with the axis of the outer cylinder. The first rotor bushing is rotatably installed on the outside of the fixed shaft, so that the first sector-shaped rotating blade fixed on the outside of the first rotor bushing rotates inside the outer cylinder. The material conveyed down from the top of the outer cylinder falls onto the first sector-shaped rotating blade.

Detailed Implementation

[0027] 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.

[0028] Example 1, please refer to Figures 1 to 4 This utility model is an airlock for preventing material blockage during unloading, including an outer cylinder 1, a rotor assembly 2, and a rotor frame assembly 3. The rotor assembly 2 includes a first rotor bushing 201, and the rotor frame assembly 3 includes a fixed shaft 301 and a set of supporting beams 302. By fixing the fixed shaft 301 in the rotor frame assembly 3 inside the outer cylinder 1 and aligning the axis of the fixed shaft 301 with the axis of the outer cylinder 1, the first rotor bushing 201 is rotatably installed outside the fixed shaft 301, causing the first sector-shaped rotating blade 202 fixed outside the first rotor bushing 201 to rotate inside the outer cylinder 1. The material conveyed from above the outer cylinder 1 falls onto the first sector-shaped rotating blade 202. The rotation of the first sector-shaped rotating blade 202 causes the material above to be swept down by the first sector-shaped partition 301a fixed outside the fixed shaft 301 to complete continuous and uniform feeding, while preventing the material from jamming the blade.

[0029] Specifically, the fixed shaft 301 is rotatably sleeved inside the outer cylinder 1, and the axis of the fixed shaft 301 coincides with the axis of the outer cylinder 1. A set of bearing seats 101 are fixedly arranged in a circumferential array on the inner wall of the outer cylinder 1. A set of bearing beams 302 are fixedly arranged in a circumferential array on the top of the fixed shaft 301. The lower end of the bearing beams 302 away from the fixed shaft 301 is fixedly installed on the upper end of each bearing seat 101. A set of first sector-shaped partitions 301a are fixedly arranged in a circumferential array on the outer side of the fixed shaft 301. A gap is left between the first sector-shaped partitions 301a and the inner wall of the outer cylinder 1. The first rotor bushing 201 is sleeved on the outer side of the fixed shaft 301 at the lower end of the first sector-shaped partitions 301a. A set of first sector-shaped rotating blades 202 are fixedly arranged in a circumferential array on the outer side of the first rotor bushing 201. The first rotor bushing 201 is connected to the output shaft of the motor through a belt.

[0030] Furthermore, a pointed beam 302a is fixedly installed above the receiving beam 302 group. The end of the pointed beam 302a away from the receiving beam 302 is pointed. When material falls on the pointed surface of the pointed beam 302a, it slides down to the bottom, preventing the material from touching the receiving beam 302.

[0031] The operation process in this embodiment is as follows:

[0032] Material is conveyed into the outer cylinder 1 from above and falls onto the first sector-shaped rotating blade 202. When the first sector-shaped rotating blade 202 rotates, the material above is swept off by the first sector-shaped baffle 301b fixed on the outside of the fixed shaft 301, thereby achieving continuous and uniform supply of material. In addition, the parallel rotating first sector-shaped rotating blade 301 effectively prevents the blade from being stuck to the inner wall of the outer cylinder 1 by material, which would cause interruption of material supply and affect production efficiency.

[0033] Example 2, please refer to Figures 1 to 7 Based on Embodiment 1, the rotor assembly also includes a sweeping plate 203.

[0034] Specifically, the end of the first sector-shaped rotating blade 202 away from the first rotor bushing 201 is an outer arc with its outer arc edge fitting against the inner wall of the outer cylinder 1. An arc-shaped vertical plate 202a is fixed above the edge of the end of the first sector-shaped rotating blade 202 away from the first rotor bushing 201. A sweeping plate beam 202b is fixed at the upper end of the side of the arc-shaped vertical plate 202a near the first rotor bushing 201. A first sector-shaped partition 301a is located between the sweeping plate beam 202b and the first sector-shaped rotating blade 202. A sweeping plate beam is fixed to the upper end of the arc-shaped vertical plate at one end of the rotor blade. A sweeping plate is installed on the sweeping plate beam. When the first rotor shaft sleeve rotates, the sweeping plate on the sweeping plate beam sweeps the material on the first sector partition down, preventing the material from accumulating on the sector partition. When the feeding system stops, the sweeping plate sweeps the material on the first sector partition down onto the first sector rotor blade. When it rotates again, the first sector partition sweeps the material above the first sector rotor blade down to complete the discharge, preventing the material from accumulating on the blade or the first sector partition.

[0035] Furthermore, the end of the sweeping plate beam 202b away from the arc-shaped vertical plate 202a extends toward the axis of the fixed axis 301, and sweeping plates 203 are installed on the sweeping plate beam 202b. The sweeping plates 203 sweep the material above the first sector-shaped partition 301a down.

[0036] Furthermore, the sweeping plate 203 has sliding grooves 203a at both ends along its length. The sweeping plate beam 202b is vertically slidably sleeved in the sliding grooves 203a. A set of compression springs 203a-1 are fixedly installed at the bottom of the sliding grooves 203a along its length. The upper end of the compression springs 203a-1 is fixedly connected to the lower end of the sweeping plate beam 202b. When the sweeping plate 203 sweeps down the material above the first sector partition 301a, it is stuck by the material. The compression springs 203a-1 are squeezed and the sweeping plate 203 is lifted, so that the sweeping plate 203 continues to rotate and avoids being stuck and causing blockage.

[0037] Furthermore, a set of second sector-shaped partitions 301b is fixed on the outer periphery of the first sector-shaped partition 301a. The edge surface of the second sector-shaped partition 301b intersects with the edge surface of the first sector-shaped partition 301a below. When the material falls from above the second sector-shaped partition 301b, it will fall on the first sector-shaped partition 301a below and be swept off by the first sector-shaped rotating blade 202. This prevents a large amount of material from accumulating on the first sector-shaped partition 301a at the same time, which could easily cause blockage and poor material supply continuity.

[0038] Furthermore, a second rotor bushing 204 is rotatably mounted on the outer periphery of the fixed shaft 301 at the lower end of the second sector-shaped partition 301b. A set of second sector-shaped rotating blades 205 are fixedly arranged in a circumferential array on the outer periphery of the second rotor bushing 204. A blade connecting arc plate 206 is fixedly mounted below the second sector-shaped rotating blades 205. The outer arc surface of the blade connecting arc plate 206 is in contact with the inner arc surface of the outer cylinder 1. The lower end of the blade connecting arc plate 206 is fixedly connected to the upper end of the arc-shaped vertical plate 202a, so that the second sector-shaped rotating blades 205 and the first sector-shaped rotating blades 202 rotate synchronously.

[0039] The operation process in this embodiment is as follows:

[0040] The material enters from above the outer cylinder 1, first falls on the second sector-shaped partition 301b, and is swept down by the sweeping plate 203 above the second sector-shaped rotating blade 205 and falls on the first sector-shaped partition 301a and the first sector-shaped rotating blade 201. Then, the first sector-shaped rotating blade 201 rotates to sweep the material down, completing the continuous and uniform discharge of the material.
