Detailed implementation manners

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] Embodiment 1: Please refer to Figure 1 - Figure 6As shown in the figure, this embodiment is a dust removal automatic trigger device for discharging bulk bags, including a discharging base 1. A sealing cylinder cover 2 is sleeved on the top edge of the discharging base 1. A bag-breaking frame body 4 facing the inside of the sealing cylinder cover 2 is sleeved and embedded at the center of the bottom of the discharging base 1. A lifting cylinder 401 penetrating the discharging base 1 is arranged at the bottom of the bag-breaking frame body 4. A rotary gate 403 slidably sleeved with the bottom of the bag-breaking frame body 4 is arranged at the top of the lifting cylinder 401;

[0028] An external discharging valve 101 cooperatively connected with the bag-breaking frame body 4 is arranged at the bottom of the outer periphery of the discharging base 1. A dust detection sensor is installed on the inner wall of the sealing cylinder cover 2 for real-time monitoring of the dust concentration in the air. When the dust concentration exceeds a preset threshold, the data collected by the dust detection sensor is sent to an external display.

[0029] A circular groove is recessed at the top of the discharging base 1. An inner inclined plate 102 facing the external discharging valve 101 is arranged on the inner wall of the circular groove. A circular hole sleeved with the lifting cylinder 401 penetrates through the middle of the circular groove of the discharging base 1.

[0030] Influenced by the arrangement of the body structure, the inner inclined plate 102 guides the goods accumulated on its surface to slide towards the external discharging valve 101, guiding the controlled discharging of the goods. In combination with the operation of the exhaust fan 303, the air in the internal space of the sealing cylinder cover 2 is extracted. The external discharging valve 101 remains open as required for discharging, guiding the external air to enter, promoting the construction of a negative pressure environment in this area, guiding the external air to enter along the area of the external discharging valve 101, and effectively preventing the dust generated during the discharging of bulk bags from leaking out;

[0031] The air flowing in from the outside to the inside here enters the sealing cylinder body along the circular groove, passes through the flipping filter plate 503, and finally accumulates inside the dust removal top cover 3. Pipe fittings and air filters connected to the outside are arranged on the outer wall of the top of the exhaust fan 303 for centrally intercepting the dust in the extracted air. Most of the dust is intercepted by the flipping filter plate 503 and accumulates between the bottom of the flipping filter plate 503 and the circular groove, facilitating subsequent centralized treatment.

[0032] The outer shape of the bag-breaking frame body 4 is designed in a conical structure. A bag-breaking cone 405 is sleeved on the top of the bag-breaking frame body 4. A plurality of groups of material guiding grooves 404 penetrating the bag-breaking frame body 4 and extending towards the rotary gate 403 are arranged at the bottom of the outer periphery of the bag-breaking cone 405. A rotary cylinder 402 is sleeved on the surface of the lifting cylinder 401. The rotary cylinder 402 is sleeved with the center of the bottom of the rotary gate 403.

[0033] The bag breaking frame 4 is driven upward by the telescopic cylinder to contact the bottom of the ton bag, and the bag breaking cone 405 is inserted into the bottom of the ton bag. The guide trough 404 guides the internal material of the ton bag to be discharged, and the rotary cylinder 402 drives the upper opening of the rotary gate 403 to dock with the bottom of the guide trough 404, so that the guide trough 404 guides the internal material of the ton bag to be unloaded onto the inner inclined plate 102. According to the unloading needs, the rotary cylinder 402 makes corresponding adjustments to temporarily adjust the unloading efficiency.

[0034] Embodiment 2: This embodiment is an automatic triggering device for dust removal during ton bag unloading, comprising a bag pressing mechanism 5 arranged on the inner wall of the sealing cylinder cover 2, the bag pressing mechanism 5 comprising a plurality of groups of supporting cylinder columns 501 which are limitedly nested on the inner wall of the sealing cylinder cover 2, a flip filter plate 503 is arranged between the plurality of groups of supporting cylinder columns 501, and a dust exhaust top cover 3 is arranged on the top of the sealing cylinder cover 2.

[0035] An arc-shaped feed groove is provided at both ends of the sealing cylinder cover 2, and symmetrical inner push cylinders 202 are embedded in the inner walls on both sides of the sealing cylinder cover 2. A rotating arc plate 201 is slidably sleeved inside the arc-shaped feed groove, and the rotating arc plate 201 is sleeved with the inner push cylinder 202.

[0036] The crane retrieves the ton bag and moves it through the arc-shaped feed chute until it is inside the sealing cylinder and then stops moving. After the ton bag is stationary, the inner push cylinder 202 drives the rotating arc plate 201 to move along the inside of the arc-shaped feed chute until the sealing cylinder is sealed, thereby preventing the dust mixed in the cargo from spilling out during the bag breaking period.

[0037] Slide plates 502 are slidably sleeved on the inner walls of the two groups of supporting cylinder columns 501 on the same side. The cross section of the slide plate 502 is hinged to the flip filter plate 503. A telescopic splicing plate 504 is nested between several groups of flip filter plates 503. A vibration motor is arranged on the surface of the slide plate 502.

[0038] When the ton bag is stationary inside the sealing cylinder, a rotating motor or a rotating cylinder connected to the flip filter plate 503 is provided on the slide plate 502 to provide power for the flip filter plate 503 to flip, causing the flip filter plate 503 to rotate along the cross section of the slide plate 502. The symmetrically arranged flip filter plates 503 are close to each other and spliced ​​into a ring. An electric push rod or a micro cylinder connected to the telescopic splicing plate 504 is provided in the middle of the ring to provide power for the telescopic splicing plate 504 to cause the telescopic splicing plate 504 to move closer to the center until it abuts against the surface of the ton bag. It should be noted that a roller or a fluid structure design may be provided on the surface of the telescopic splicing plate 504 close to the bag body of the ton bag to avoid jamming between the telescopic splicing plate 504 and the bag body of the ton bag.

[0039] Arc-shaped notches are symmetrically and penetratingly arranged at both ends of the dust extraction top cover 3. An adapting air cylinder 302 is sleeved and arranged on the inner wall of the arc-shaped notch. An adapting baffle 301 which is slidably connected with the arc-shaped notch is arranged on the inner wall of the adapting air cylinder 302. An exhaust fan 303 is sleeved and arranged on the top of the dust extraction top cover 3.

[0040] As the ton bag is punctured and unloaded, the top bag body of the ton bag is gradually deformed. The supporting air cylinder column 501 drives several groups of sliding plates 502 to slide down simultaneously, so that the telescopic splicing plate 504 contacts the ton bag and binds the ton bag body. The vibration motor arranged on the sliding plate 502 transmits the vibration to the sliding plate 502, the flipping filter plate 503 and the telescopic splicing plate 504 through accessories. Accordingly, the flipping filter plate 503 filters the filtered dust. Under the continuous vibration effect, the dust is prevented from blocking the flipping filter plate 503. The telescopic splicing plate 504 contacts the ton bag body and guides the vibration to be transmitted to the ton bag, so that the part of the ton bag body that is centrally limited conducts the vibration, which helps the materials and dust attached to the inner wall of the ton bag to fall off.

[0041] The ton bag filled with goods is lifted by a crane in the factory area. The cross beam of the crane is sleeved inside the arc-shaped notch of the dust extraction top cover 3. The adapting baffle 301 changes the model according to the cross beam of the crane, so that a slot adapted to the cross beam of the crane is opened on the plate body of the adapting baffle 301, so as to seal the dust extraction top cover 3 during the bag breaking and unloading process and reduce the dust from overflowing along the inside.

[0042] Combining Embodiment 1 and Embodiment 2, it can be seen that the efficiency and safety are improved from multiple dimensions of sealing, dust removal and unloading. In terms of sealing, the adapting baffle 301 cooperates with the rotating arc plate 201 to achieve full-closed unloading throughout the process, prevent dust explosion, and reduce the equipment maintenance cost. In terms of dust removal, the flipping filter plate 503 and the telescopic splicing plate 504 are combined with the vibration motor to dynamically restrict the ton bag, prevent the filter plate from being blocked, and improve the dust removal and unloading efficiency. In terms of unloading, each component cooperates to achieve precise and controllable unloading. At the same time, the exhaust fan 303 and the discharge external valve 101 construct a negative pressure environment to form a directional dust removal path, and the double interception ensures the air cleanliness, achieving the integrated and efficient operation of unloading and dust removal.

The preferred embodiments do not describe all the details in detail, nor do they limit the present invention to the specific embodiments. Obviously, many modifications and changes can be made according to the content of this specification.
