Description

Technical Field

[0001] This utility model relates to the field of dust conveying technology, and in particular to a semi-naked auger conveyor. Background Technology

[0002] In dusty production and transportation, conveyor belts face the dual challenges of dust pollution and difficulty in uniform paving: on the one hand, dust is dispersed due to induced wind effect and secondary dust during unloading / turning, polluting the environment and potentially exceeding environmental standards, while also threatening the health of workers; on the other hand, the poor fluidity of dust, uneven particle size, and insufficient adaptability of conveyor belt structure to operating parameters, coupled with environmental interference, easily lead to accumulation, ditching, or adhesion, resulting in high deviations in paving thickness and affecting the efficiency of subsequent processes.

[0003] Therefore, it is necessary to provide a semi-naked auger conveyor to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a semi-naked auger conveyor that solves the problem of excessive dust and difficulty in evenly distributing powder during the existing powder dispersion process using conveyor belts. The auger utilizes rotating blades to propel the powder upwards, achieving even powder distribution under the combined action of centrifugal force and gravity.

[0005] To achieve the above objectives, this utility model provides a semi-naked auger conveyor, including an auger conveyor and a semi-naked outer shell. The semi-naked outer shell is fixed above the auger conveyor and is arc-shaped. A shielding device is provided at the arc-shaped boundary of the semi-naked outer shell.

[0006] Preferably, the auger conveyor includes a rotating shaft and a spiral blade fixedly connected to the rotating shaft. The spiral blade is arranged along the axial direction of the rotating shaft and is a ribbon-shaped blade. The top end of the rotating shaft and the semi-naked outer shell are both fixedly mounted on a fixed base.

[0007] Preferably, the semi-naked shell is provided with a hoisting handle for suspending the steel wire rope in the middle, and the semi-naked shell is provided with a fixed railing on the outside.

[0008] Preferably, the shielding device includes a connecting plate and a lightweight shielding plate, the connecting plate being fixedly disposed at the arc-shaped boundary of the semi-exposed shell, and the lightweight shielding plate being movably connected to the connecting plate.

[0009] Preferably, the connecting plate has a groove and a suspension strip that are interconnected in the middle, and the suspension strip is disposed above the groove.

[0010] Preferably, a hanging ear is provided on the upper part of the lightweight shielding plate, and the hanging ear is embedded in the groove of the connecting plate and the suspension strip.

[0011] Preferably, the connecting plate has a movable part at its tail end, and the lightweight shielding plate has a stop block at its tail end. The stop block is disposed in the movable part, the movable part is connected to the groove, the width of the movable part is greater than the width of the suspension strip, and the movable part is provided with a magnetic supplement block for restraining the movement of the lightweight shielding plate.

[0012] Preferably, the auger conveyor and the semi-naked shell are provided with a loading platform at the end away from the fixed base. The motor of the auger conveyor is installed in the loading platform. The semi-naked shell is fixed to the loading platform. The loading platform is provided with a baffle, which is located below the auger conveyor.

[0013] Therefore, the present invention employs the above-mentioned semi-naked auger conveyor, which has the following beneficial effects:

[0014] (1) This utility model utilizes an unclosed auger conveyor to transport dust while allowing it to fall evenly below the auger conveyor. It is a combination of gravity-driven particle movement at low speed, combined with the spiral structure parameters and powder properties.

[0015] (2) This utility model adds a semi-enclosed shell above the auger conveyor and installs a shielding device around it to avoid dust from being generated during the transportation and turning process of the powder, thereby alleviating the environmental problems of the production site and protecting the safety of workers.

[0016] (3) This utility model has simple functions and is easy to use. It avoids dust accumulation, channeling or sticking, and makes it fall evenly and accumulate little by little under the auger conveyor.

[0027] As per the instruction manual Figure 1-4 As shown, this utility model discloses a semi-naked auger conveyor, including an auger conveyor 1 and a semi-naked outer shell 3. The semi-naked outer shell 3 is fixed above the auger conveyor 1. The semi-naked outer shell 3 is arc-shaped, covering the upper part of the auger conveyor 1 to avoid the problem of powder being thrown upward. A shielding device is provided at the arc-shaped boundary of the semi-naked outer shell 3 to cover both sides of the auger conveyor 1, leaving only the lower outlet, so that the powder slowly accumulates below the auger conveyor.

[0028] The auger conveyor 1 includes a rotating shaft and helical blades fixedly connected to the rotating shaft. The helical blades are ribbon-shaped blades with small pitch and large diameter to increase the contact area between the blades and the material, improve the driving force, and reduce the effective speed requirement. The helical blades are arranged along the axial direction of the rotating shaft, and the top of the rotating shaft and the semi-exposed outer casing 3 are both fixedly mounted on the fixed base 2. The fixed base 2 is generally fixed to the ceiling of the production site, allowing the auger conveyor 1 to tilt at an angle.

[0029] A lifting handle 4 for suspending the steel wire rope is provided in the middle of the semi-exposed shell 3. The steel wire rope is subjected to a certain tension to maintain the tilt stability of the auger conveyor 1. A fixed railing 5 is provided on the outside of the semi-exposed shell 3.

[0030] The shielding device includes a connecting plate 8 and a lightweight shielding plate 9. The connecting plate 8 is fixedly installed at the arc-shaped boundary of the semi-naked shell 3. The lightweight shielding plate 9 is movably connected to the connecting plate 8 and slides up and down at the connecting plate 8.

[0031] The connecting plate 8 has a groove 11 and a hanging strip 12 that are interconnected in the middle. The groove 11 is located on the inner side, and the hanging strip 12 is located above the groove 11. The lightweight shielding plate 9 has a hanging ear 10 on its upper side, which is embedded in the groove 11 and the hanging strip 12 of the connecting plate 8.

[0032] The connecting plate 8 has a movable part 13 at its tail end, and the lightweight shield 9 has a stop block 15 at its tail end. The stop block 15 is located inside the movable part 13, which is connected to the groove 11. The width of the movable part 13 is greater than the width of the hanging strip 12. The movable part 13 is provided with a magnetic supplement block 14 for restraining the movement of the lightweight shield 9. When the lightweight shield 9 needs to be hung, the hanging ear 10 is placed in the groove 11 and slids in the groove 11 to achieve shielding from the bottom to the top of the semi-naked shell 3. Finally, the magnetic supplement block 14 is placed at the tail end of the stop block 15 and magnetically fixed to the connecting plate 8.

[0033] A loading platform 6 is provided at the end of the auger conveyor 1 and the semi-naked shell 3 away from the fixed base 2. The motor of the auger conveyor 1 is installed inside the loading platform 6. The semi-naked shell 3 is fixed on the loading platform 6. The loading platform 6 is provided with a baffle 7, which is located below the auger conveyor 1 to prevent dust from accumulating from one side below.

[0034] Therefore, the semi-naked auger conveyor disclosed in this utility model solves the problem of large amounts of dust and difficulty in evenly distributing powder during the existing powder dispersion process using conveyor belts. It utilizes the rotating blades of the auger to propel the powder upwards, achieving even powder distribution under the combined action of centrifugal force and gravity.
