Technical Field
[0001] This utility model belongs to the technical field of dust removal equipment, specifically relating to a dust removal system for the material drop point of a reversible belt conveyor. Background Technology
[0002] Application No. 202322422830.0 discloses a dust removal device for a reversible mobile distribution conveyor belt. Through the cooperation of the reversible distribution conveyor belt sealing cover, dust removal branch pipes on the silo, dust removal main pipe, dust removal branch pipes below the silo, dust removal cover below the silo, and rubber soft curtain, a slight negative pressure is formed inside the silo body and the reversible distribution conveyor belt sealing cover, reducing dust escape and resulting in low dust concentration during equipment filling.

The adjusting screw can drive the clamping plate to move, and with the cooperation of the limiting hole and limiting rod, the clamping plate can move stably, fixing and releasing the rubber soft curtain.
[0003] However, existing dust removal systems require the collection and cleaning of accumulated dust after a period of operation; otherwise, the dust removal effect will be reduced, affecting subsequent dust removal efficiency. Currently, the collection and cleaning of accumulated dust mostly relies on manual labor using forklifts to recycle dust bags and other structures, which cannot achieve automatic collection, is time-consuming and labor-intensive, and has poor practicality.

[0008] Preferably, each of the four corners of the top plate is fixedly installed with a column, and each of the four corners of the dust bag is equipped with a pull rope. The pull rope corresponds to each column, and the end of the pull rope away from the dust bag is located on the outer wall of the column.
[0009] Preferably, the top of the mounting frame is provided with a belt alignment device and a buffer bed, both of which are in contact with the upper belt of the reversible belt conveyor; a canopy is provided above the mounting frame, and two hangers are symmetrically installed at the bottom of the canopy. The bottom of the two hangers is provided with a material guide chute, which covers the outside of the reversible belt conveyor. A drop pipe and two dust collectors are respectively provided on the top of the material guide chute. The drop pipe is located at the center of the material guide chute, and the two dust collectors are symmetrically arranged on both sides of the drop pipe. The buffer bed is located directly below the drop pipe.
[0010] Preferably, both the dust cover and the opening of the guide chute are provided with sealing soft curtains, which are in close contact with the reversible belt conveyor; a control box is fixedly installed on the outer wall of the dust cover.
[0011] Preferably, the bottom of the dust cover is provided with support wheels.
[0012] In addition, the reversible belt conveyor material discharge point dust removal system in the above-mentioned technical solution provided by this utility model may also have the following features: the bottom of the pulse dust collector is provided with a dust hopper, a sleeve plate is welded on the outer wall of the dust hopper, and an inner baffle is slidably connected inside the dust hopper; one end of the inner baffle extends slidably out of the dust hopper and is equipped with a connecting plate, and two hydraulic cylinders are symmetrically installed on the top of the sleeve plate, and an output shaft is provided at the output end of the hydraulic cylinder.
[0013] In the above technical solution, the end of the output shaft away from the hydraulic cylinder is connected to the connecting plate.
[0014] The dust removal system at the material discharge point of this reversible belt conveyor has the following advantages compared with the prior art:
[0015] 1. The dust removal system at the material discharge point of this reversible belt conveyor directly installs the dust collector on the reversible belt conveyor, eliminating secondary land occupation, providing high filtration accuracy, and ensuring that the effective airflow directly acts on the dust generation point, thereby reducing energy consumption;
[0016] 2. The dust removal system at the material drop point of this reversible belt conveyor is equipped with a buffer bed at the belt directly below the material drop pipe. The buffer bed effectively absorbs the impact generated when the material falls, preventing damage to the conveyor belt and conveyor frame.
[0017] 3. The dust removal system at the material discharge point of this reversible belt conveyor uses a hydraulic cylinder to move the inner baffle, causing the discharge port to open and close periodically. This allows accumulated dust to be periodically discharged into the dust collection bag below. A gravity sensor measures the weight of the top plate. When dust enters the dust collection bag, the weight of the top plate increases, and the gravity sensor feeds this information back to the external control system. This causes the control system to start the external motor, which drives the lead screw to rotate. The lead screw moves the dust collection bag, causing the dust-filled bag to move out of the opening and the empty bag to move into the opening, thus achieving the effect of automatic dust collection.

[0034] The reversible belt conveyor, pulse dust collector, belt alignment device, dust collector, buffer bed, sealing curtain, hydraulic cylinder, and gravity sensor mentioned in this case are existing technologies. The reversible belt conveyor and sealing curtain have the same structure and connection method as those in the cited documents. As long as the reversible belt conveyor, pulse dust collector, belt alignment device, dust collector, buffer bed, sealing curtain, hydraulic cylinder, and gravity sensor meet the requirements of this case, they are all acceptable and not limited to a single model.
[0035] Working principle: All electrical components mentioned in this application are externally connected to a power supply and control switch during use. After installation, first check the installation, fixation, and safety precautions of this utility model before use. During use, material is fed onto the reversible belt conveyor 2 through the material drop pipe 9. Starting the reversible belt conveyor 2 allows it to transport the material. The buffer bed 15 effectively absorbs the impact generated when the material falls, preventing damage to the conveyor belt and conveyor frame. The dust collector 11 initially removes some of the dust located in the guide trough 7. The material is then absorbed; subsequently, it is conveyed to the head of the machine via a reversible belt conveyor 2, enters the dust cover 3, and is discharged into the discharge chamber 32. The dust suction pipe 12 promptly draws the dust generated during the discharge process into the pulse dust collector 4. Some of the coarse particles in the airflow settle into the dust hopper 41 under the action of inertial force, while fine dust particles are deposited on the outer surface of the filter cartridge. When the dust layer on the surface of the filter cartridge is thick, the pulse controller issues a command to open the jet valve, and the compressed air rapidly expands in the chamber in a short time and rushes into the filter cartridge, causing the filter cartridge to expand. The system vibrates, and under the scouring action of the reverse airflow, the dust adhering to the outer surface of the filter bag is stripped off and eventually falls into the dust collection hopper 41. At regular intervals, the hydraulic cylinder 414 is activated, causing the output shaft 415 to move. The output shaft 415 then moves the connecting plate 413 and the inner baffle 412, opening the discharge port of the dust collection hopper 41. The dust inside falls into the dust collection bag 56. After one discharge, the hydraulic cylinder 414 moves the output shaft 415 back, causing the inner baffle 412 to move back and block the discharge port. The dust collection bag 56... As internal dust accumulates, the weight on the top plate 55 increases. The gravity sensor 54 transmits a signal to the wireless acquisition module, which connects to the platform via a 4G antenna. The platform then feeds the information back to the external control system, which starts the external motor. This motor drives the lead screw 59 to rotate, and the lead screw 59 drives the inner slider 52 to slide within the slide groove 51. This causes the full dust bag 56 to detach from the opening 31, and the empty dust bag 56 to enter the opening 31, ready for the next dust collection cycle. This achieves the effect of automatic dust collection.
