Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, specifically a closed pipeline conveying device. Background Technology

[0002] Dry granulation is a method used in the pharmaceutical, food, and chemical industries to granulate powdered materials. This method does not require the addition of liquid solvents or binders, hence the name "dry." Dry granulation uses a dry granulator for processing. The vibration of the dry granulator can cause powder to diffuse into the air, posing a hazard and requiring artificial respiration protection.

[0003] Chinese invention patent CN111509635A, published on August 7, 2020, discloses a bellows connector, including a bellows, multiple stabilizing devices disposed on the sidewalls at both ends of the bellows, a wire-binding device disposed at one end of the bellows, fixing devices disposed at both ends of the bellows, and a sealing device disposed on one side of the wire-binding device. The sealing device includes a sealing groove disposed at one end of the bellows, a vent hole passing through one end of the bellows, a sealing ring disposed on the sealing groove, and a vent buckle for connecting the sealing ring and the vent hole. A check valve is provided on the vent hole, and the sealing ring is made of an elastic material. This invention, through the setting of the sealing ring, allows air to be vented through the vent hole after the bellows and the installation position are fixed. Subsequently, the sealing ring expands, causing it to tightly adhere to the connection, sealing and fixing the connection, increasing the stability of the bellows connection, and avoiding instability in the connection caused by assembly errors between the bellows and the installation position.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the existing corrugated pipe connector can be used as a flexible pipe connection between the dry granulator and the ternary vibrating screen equipment, but it cannot actively pass objects through and does not transfer the dry granulator for subsequent screening work of the ternary vibrating screen. Therefore, it is necessary to improve it so as to actively transfer particulate matter while isolating the outside world. Utility Model Content

[0005] The purpose of this invention is to solve the problem that while existing corrugated pipe connectors can be used as flexible pipe connections between dry granulators and ternary vibrating screens, they cannot actively allow objects to pass through and cannot transfer particles from the dry granulator to the subsequent ternary vibrating screen. Therefore, it is necessary to improve the technology to actively transfer particulate matter while isolating it from the outside environment, and to provide a closed-loop pipeline conveying device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention discloses a closed pipeline conveying device, comprising a corrugated pipe; one end of the corrugated pipe is connected and fixedly connected to a vacuum feeder, and the other end is connected and fixedly connected to a dry granulation machine; the lower outlet of the vacuum feeder is connected and fixedly connected to a three-dimensional vibrating screen; a vent is sleeved on the lower end of the vacuum feeder; a traction rope is inserted through an opening in the vent; a fixed block is sleeved on the traction rope; a rope-threading groove is opened in the fixed block corresponding to the traction rope; an extrusion plate is slidably inserted into the rope-threading groove; and fasteners are threadedly inserted through an opening in the fixed block corresponding to the extrusion plate.

[0008] Furthermore, multiple limiting rings are sleeved on the corrugated pipe; pins are inserted into the limiting rings; and adjusting ropes are fixed between the pins.

[0009] Furthermore, the adjusting rope is symmetrically connected to limit wheels via rolling friction; functional plates are symmetrically sleeved on the limit wheels.

[0010] The closed-loop pipeline conveying device provided by this utility model has the following beneficial effects:

[0011] 1. This utility model has fixed blocks attached to both ends of the traction rope; the fixed blocks have rope grooves corresponding to the traction rope; the rope grooves are slidably inserted into the rope grooves; and fasteners are threaded into the holes on the fixed blocks corresponding to the openings of the extrusion plates. Then, the ternary vibrating screen is tightly wrapped by fixing the length of the traction rope in the vent. The fixed length can be adjusted by simply rotating the fasteners to push the extrusion plates to squeeze the traction rope. This allows the particles to be sealed and automatically transported from the dry granulator to the ternary vibrating screen without polluting the air in the factory and causing harm to personnel.

[0012] 2. This utility model uses two pins located at both ends of the adjusting rope, which makes the connection with the limiting ring more stable and quick, making it more convenient to install and fix. At the same time, the shape of the corrugated tube can be adjusted by adjusting the height of the two ends of the adjusting rope, and the positions of the two limiting rings at both ends of the corrugated tube can be changed. Thus, the shape of the corrugated tube and the height difference between the two ends can be adjusted as needed to adapt to different requirements. Attached Figure Description

[0018] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0021] Please see Figure 1-3 As shown, a closed-loop pipeline conveying device includes a corrugated pipe 1; one end of the corrugated pipe 1 is connected to a vacuum feeder 2 and the other end is connected to a dry granulation machine. The corrugated pipe 1 is used to constrain the movement path of particles and powders, preventing them from diffusing into the air and causing contamination to personnel's breathing. The vacuum feeder 2 then extracts the granulated drug under negative pressure. The lower outlet of the vacuum feeder 2 is then connected to a ternary vibrating screen for further screening. A vent hood 3 is fitted onto the lower end of the vacuum feeder 2; a traction rope 4 is inserted into an opening inside the vent hood 3, and the traction rope 4 is looped around the ternary vibrating screen, allowing the lower end of the vacuum feeder 2 to be ventilated. Air can be discharged through the vent 3; fixed blocks 5 are attached to both ends of the traction rope 4; a rope groove 6 is opened in the fixed block 5 corresponding to the traction rope 4; a pressing plate 7 is slidably inserted in the rope groove 6; a fastener 8 is threaded into the fixed block 5 corresponding to the pressing plate 7; and then, to fix the length of the traction rope 4 in the vent 3 to tightly cover the ternary vibrating screen, simply rotate the fastener 8 to push the pressing plate 7 to press the traction rope 4 to fix and adjust the length, so that particles can be sealed and automatically transported from the dry granulator to the ternary vibrating screen, without polluting the air in the factory and causing harm to personnel.

[0022] Multiple limiting rings 9 are fitted onto the corrugated pipe 1; pins 10 are inserted into the limiting rings 9; an adjusting rope 11 is fixed between the pins 10. The two pins 10 are located at the two ends of the adjusting rope 11, which makes the connection with the limiting rings 9 more stable and quick, making it more convenient to install and fix. At the same time, the shape of the corrugated pipe 1 can be adjusted by adjusting the height of the two ends of the adjusting rope 11, and the positions of the two limiting rings 9 at the two ends of the corrugated pipe 1 can be changed. Thus, the shape of the corrugated pipe 1 and the height difference between the two ends can be adjusted as needed to adapt to different requirements.

[0023] The adjusting rope 11 is symmetrically connected to the limiting wheels 13 by rolling friction; the limiting wheels 13 are symmetrically sleeved with functional plates 12, which restrict the position of the two limiting wheels 13, and then the two limiting wheels 13 are used to restrict the displacement of the adjusting rope 11, thereby making it more efficient to adjust the distribution ratio at both ends of the adjusting rope 11.

[0024] A drive wheel 14 is rotatably connected to the corresponding limit wheel 13 between the function plates 12; a hexagonal hole 15 is provided on the side of the drive wheel 14. By inserting a hexagonal wrench into the hexagonal hole 15 to rotate, the drive wheel 14 and the limit wheel 13 can be rotated, thereby changing the length ratio of the two ends of the adjusting rope 11, thereby adjusting the shape of the corrugated pipe 1, thereby suspending and fixing and adjusting the corrugated pipe 1, thereby avoiding other objects and maximizing the vacuum suction of the vacuum feeder 2.

[0025] A friction tube 16 is inserted into the function plate 12, which allows it to be connected to shaft-like objects, so that the function plate 12 can be suspended and fixedly installed.

[0026] A hanging rope 17 is inserted into the friction tube 16. The hanging rope 17 can be used to easily connect and fix it to other objects, making the fixing methods more diverse and stable.
