[0031] like Figures 1-4 As shown, in an embodiment of the dust-free modular telescopic vertical unloader provided by this utility model, the dust-free modular telescopic vertical unloader includes at least:

[0032] The filter unit 1 includes an outer cylinder 11, a discharge cylinder 12, a partition 13, and a filter structure 14. The outer cylinder 11 is sealed at the top and open at the bottom. The discharge cylinder 12 is inserted into the outer cylinder 11 from the top and is fixedly connected to it. A first channel exists between the discharge cylinder 12 and the outer cylinder 11. The partition 13 divides the first channel into upper and lower sections. The filter structure 14 is disposed on the partition 13 to allow airflow between the upper and lower sections of the first channel. An air vent 111 for the first channel is provided on the outer cylinder 11, located above the partition 13.

[0033] The telescopic unit 2 includes a telescopic cylinder 21 and a discharge structure. The telescopic cylinder 21 has a variable longitudinal height and its top end is connected to the outer cylinder 11. The discharge structure, always located inside the telescopic cylinder 21, has a flexible or telescopic discharge channel, the top end of which is connected to the bottom end of the discharge cylinder 12. A second channel exists between the discharge channel and the telescopic cylinder 21. The top end of the second channel connects to the first channel, and the bottom end connects to the outside of the telescopic cylinder 21.

[0034] When the dust-free modular telescopic vertical unloader is in use, the bottom of the telescopic unit 2 hangs freely to its longest position, and the bottom of the unloading channel is located above the unloading area. The material flows from the top of the unloading cylinder 12, through the unloading cylinder 12 and the unloading channel, and then falls into the unloading area. The dust generated when the material falls into the unloading area will enter the space between the unloading structure and the telescopic cylinder 21 and continue to rise under the influence of airflow, and will eventually be trapped in the dust-free modular telescopic vertical unloader by the filter structure 14; excess gas in the first channel is discharged from the outer cylinder 11 through the air outlet 111 to prevent excessive pressure in the first and second channels.

[0035] With the help of the partition 13 and the filter structure 14 in the filter unit 1, the dust-free combined telescopic vertical unloading machine can trap most of the dust in the outer cylinder 11, and even if a small amount of dust reaches above the partition 13, it can also settle in the outer cylinder 11 under the action of its own gravity and the cylinder wall of the outer cylinder 11, thereby reducing the possibility of dust escaping from the unloading machine.

[0036] When the dust-free combined telescopic vertical unloading machine is not in unloading operation, an external force can be used to lift the telescopic cylinder 21 and the bottom of the unloading structure, causing the telescopic cylinder 21 to shrink upwards, and during this period, the unloading structure is always inside the telescopic cylinder 21.

[0037] In some embodiments, the first channel is the interlayer between the unloading cylinder 12 and the outer cylinder 11, and the second channel is the interlayer between the unloading channel and the telescopic cylinder 21.

[0038] In some embodiments, the unloading machine further comprises a ventilation unit 3 connected to the air outlet 111 for extracting air from the outer cylinder 11 to accelerate the filtration of dust.

[0039] Specifically, the ventilation unit 3 has a fan 31 for extracting air from the outer cylinder 11.

[0040] In some embodiments, the ventilation unit 3 is also used to send air into the outer cylinder 11, so that when the filter holes of the filter structure 14 are blocked, the airflow is driven to flow reversely from top to bottom through the filter structure 14, and the filter holes of the filter structure 14 are flushed open.

[0041] Specifically, the ventilation unit 3 also has an air bag 32 and a valve, and the air bag 32 is connected to the valve; two air outlets 111 are provided on the outer cylinder 11, one air outlet 111 is connected to the fan 31 for extracting air from the outer cylinder 11, and the other air outlet 111 is connected to the valve for sending air in the air bag 32 into the outer cylinder 11. The valve is not shown in the figure.

[0042] In some embodiments, multiple filter structures 14 are provided around the unloading cylinder 12.

[0043] In some embodiments, the filter structure 14 is a filter cylinder to increase the filtering area of the filter structure 14 and improve the filtering efficiency.

[0044] In some embodiments, the unloading machine further comprises a limiting structure located above the partition 13 and fixedly connected to the filter cylinder passing through the partition 13 to prevent the filter cylinder from separating from the partition 13.

[0045] Specifically, the limiting structure includes a flange, and each filter cartridge is fixed with a flange at the top end. The partition plate 13 is provided with through holes corresponding to the filter cartridges, and each filter cartridge is inserted into the corresponding through hole. There is a gap between the through hole and the filter cartridge to facilitate the installation of the filter cartridge into the through hole. The gap between the through hole and the filter cartridge is blocked by the flange. The flange is not shown in the figure.

[0046] Specifically, the limiting structure further includes a bolt, and each flange is fixed to the top surface of the partition plate 13 by a plurality of bolts, and the bolts are screwed through the flange and the partition plate 13 to improve the connection reliability between the filter cartridge and the partition plate 13, and facilitate the disassembly and replacement of the filter cartridge. All the bolts on each flange are annularly distributed around the axis of the flange. The bolts are not shown in the figure.

[0047] In some embodiments, the telescopic cylinder 21 is a flexible thin-walled structure, for example, the telescopic cylinder 21 can be a cylindrical structure composed of a plastic film or a woven cloth. The telescopic cylinder 21 is preferably made of canvas. When the telescopic cylinder 21 is telescoped upward, the side walls of the telescopic cylinder 21 are stacked together to realize the shortening of the longitudinal length of the telescopic cylinder 21.

[0048] In some embodiments, the discharge structure is composed of a plurality of longitudinally arranged discharge members 22. The discharge member 22 includes a fixed ring 221, a support rib 222, and an inverted cone cylinder 223. The inverted cone cylinder 223 is located inside the fixed ring 221, and the inverted cone cylinder 223 and the fixed ring 221 are connected by the support rib 222. The fixed ring 221 is connected to the inner side of the telescopic cylinder 21. When the longitudinal length of the telescopic cylinder 21 is shortened, the bottom end of each inverted cone cylinder 223 is inserted into the top end of the adjacent inverted cone cylinder 223 below. The inner sides of all the inverted cone cylinders 223 are communicated to form a discharge channel. The bottom end of the discharge cylinder 12 is inserted into the top of the uppermost inverted cone cylinder 223. The bottom end of the telescopic cylinder 21 is free to hang down. When the telescopic cylinder 21 is in the state of maximum longitudinal height, the axes of all the inverted cone cylinders 223 tend to be collinear to ensure that the falling material from the discharge cylinder 12 can pass through all the inverted cone cylinders 223 in turn from top to bottom. When the telescopic cylinder 21 is at the maximum longitudinal height, the dust generated by the impact of the material on the inverted cone cylinder 223 can enter the second channel through the gap between the abutting positions of two adjacent inverted cone cylinders 223.

[0049] In some embodiments, the discharge structure further includes a connecting rope 8, which is used to connect all the discharge members 22 in series. Multiple connecting ropes 8 are provided, and all the connecting ropes 8 are distributed around the axis of the telescopic cylinder 21.

[0050] Specifically, the connecting rope 8 connects all the support ribs 222 of the discharge members 22 in series.

[0051] In some embodiments, a hoop is used to detachably mount the top end of the telescopic cylinder 21 to the outside of the bottom end of the outer cylinder 11. The hoop is a commonly used connecting piece 101 for pipelines, and its structure is not described here.

[0052] Specifically, the outer cylinder 11 is provided with a limiting ring 112 at the bottom end, and the hoop is arranged above the limiting ring 112, and the limiting ring 112 is used to prevent the hoop from being separated from the outer cylinder 11. Figure 1 The hoop and the limiting ring 112 are not shown in the figure.

[0053] In some embodiments, the unloading machine further comprises a traction rope 4, one end of which is connected to the bottom of the telescopic cylinder 21 and the bottom of the unloading structure. When the traction rope 4 is pulled upward, the telescopic unit 2 is retracted upward. When the traction rope 4 is released, the telescopic unit 2 freely hangs in a state of maximum longitudinal length.

[0054] Specifically, the unloading machine further comprises a limiting plate 10, a hook 7 and a connecting piece 101. The limiting plate 10 is arranged at the bottom end of the telescopic cylinder 21, the connecting piece 101 is arranged at the bottom of the lowermost inverted cone cylinder 223, the traction rope 4 is connected with the hook 7 after passing through the limiting plate 10, and the hook 7 hooks the connecting piece 101. The traction rope 4 is connected with the lowermost inverted cone cylinder 223 through the hook 7 and the connecting piece 101.

[0055] Specifically, the unloading machine further comprises a power device 5 arranged above the telescopic cylinder 21, and the traction rope 4 is wound on the output end of the power device 5. The output end of the power device 5 rotates to change the length of the traction rope 4 wound on the output end of the power device 5, so as to drive the bottom end of the telescopic unit 2 to move up and down.

[0056] Specifically, the unloading machine further comprises a guide wheel 6 rotatably connected above the outer cylinder 11. The traction rope 4 is provided in plurality, and the bottom ends of all the traction ropes 4 are distributed around the axis of the telescopic cylinder 21 and are detachably connected with the telescopic cylinder 21. The guide wheel 6 corresponds to the traction rope 4 one by one, each traction rope 4 passes through the corresponding guide wheel 6 and is connected with the output end of the power device 5. Each guide wheel 6 is arranged above the bottom end of the corresponding traction rope 4, so that the traction rope 4 between the guide wheel 6 and the bottom end of the telescopic cylinder 21 is in a vertical state, and the guide wheel 6 is used to change the direction of the traction rope 4, so that the traction rope 4 between the guide wheel 6 and the power device 5 is in a horizontal state.

[0057] In some embodiments, the unloading machine further comprises a rack 9, and the outer cylinder 11, the power device 5 and the ventilation unit 3 are all arranged on the rack 9.

[0058] The specific structure and working process of an embodiment of the dust-free combined telescopic vertical unloading machine will be described below with reference to the accompanying drawings. Figures 1-4 The specific structure and working process of an embodiment of the dust-free combined telescopic vertical unloading machine will be described below with reference to the accompanying drawings.

[0059] When the dust-free combined telescopic vertical unloading machine is used, the bottom end of the telescopic unit 2 freely hangs to the longest state, and the bottom end of the unloading channel is located above the unloading area. The material falls to the unloading area after sequentially flowing through the unloading cylinder 12 and the unloading channel from the top end of the unloading cylinder 12. The dust generated when the material falls to the unloading area can enter the space between the unloading structure and the telescopic cylinder 21 and continue to go upward under the action of the airflow, and finally be intercepted by the filtering structure 14 in the dust-free combined telescopic vertical unloading machine. The excess gas in the first channel is discharged from the air port 111 to the outer cylinder 11, so as to prevent the pressure in the first channel and the second channel from being too large.

[0060] When the dust-free combined telescopic vertical unloading machine does not perform the unloading operation, the power device 5 can be used to lift the bottom of the telescopic cylinder 21 and the unloading structure through the traction rope 4, so that the telescopic cylinder 21 is upwardly retracted, and during the period, the unloading structure is always located inside the telescopic cylinder 21.

[0061] It can be seen from the description of the plurality of embodiments of the dust-free combined telescopic vertical unloading machine that the dust-free combined telescopic vertical unloading machine embodiment has at least one or more of the following advantages:

[0062] 1. The dust-free combined telescopic vertical unloading machine provided by the utility model can intercept most of the dust in the outer cylinder 11 through the partition plate 13 and the filtering structure 14 in the filtering unit 1. Even if a small amount of dust reaches above the partition plate 13, the dust can also settle in the outer cylinder 11 under the action of its own gravity and the cylinder wall of the outer cylinder 11, thereby reducing the possibility of the dust escaping from the unloading machine.

[0063] 2. The ventilation device is arranged in the utility model to accelerate the filtration of the dust. Meanwhile, the ventilation device can also reversely send air to flush the filter holes of the filtering structure 14 when the filter holes of the filtering structure 14 are blocked.

[0064] It should be noted finally that: the embodiments in the specification are described in a progressive manner, and each embodiment mainly explains the differences from other embodiments. The same and similar parts of each embodiment can be referred to. Figures 1-4 It should not be regarded as a limitation on the combination mode of the plurality of embodiments of the utility model.
