Description

Technical Field

[0001] The present invention relates to a bulk loading machine with a dust collection module, and particularly to a bulk loading machine with a dust collection module for use in the field of bulk loading machines. Background Technology

[0002] Bulk material handling equipment is widely used in industries such as cement, ore, coal, and steel. Since its inception, bulk loading machines for automobiles, trains, and ships have made great progress in terms of structure, mechanism, and materials. The working principle of bulk loading machines mainly includes three processes: feeding, spreading, and collecting.

[0003] To address the issue of loading dry powdery materials into bulk tank trucks, a certain bulk loading machine on the market employs a dust extraction system and has a certain market share.

[0004] Chinese patent CN110980339B discloses a dry ash bulk loading machine, including a steel base. A drive bracket is fixedly installed on one side of the upper surface of the steel base, a drive device is fixedly installed on one side of the upper surface of the drive bracket, a winch device is fixedly installed on the other side of the upper surface of the drive bracket, and a slack rope device is fixedly installed on the upper surface of the winch device. Compared with the prior art, this invention uses a telescopic rod in conjunction with a motor, allowing the distribution head to extend, retract, and rotate. This enables the material to be dispersed in all directions during loading into the ash loading compartment through the centrifugal force of the distribution head, achieving full loading of the material. This solves the problem that material falling directly into the ash loading compartment will accumulate in a triangular shape, preventing material from being loaded onto the upper sides of the compartment. This increases the material loading capacity of the equipment and thus speeds up the unloading speed of the material in the silo.

[0005] Current bulk material loader machines generate significant dust during bulk material feeding. While they can attract dust, they only guide it out, requiring subsequent centralized treatment of the discharged dust, which is quite troublesome. Therefore, a bulk loader machine with a dust collection module is needed to reduce dust generation during bulk material feeding. Summary of the Invention

[0006] The technical problem that this invention aims to solve in view of the above-mentioned prior art is that, considering the current domestic and foreign bulk material handling machines, dust generation is severe during bulk material feeding.

[0007] To solve the above problems, the present invention provides a bulk loading machine with a dust collection module, including a mounting frame, on which a dust collection module is connected, and a material conveying pipe and a dust extraction module are respectively connected to the upper and lower ends of the dust collection module.

[0008] The dust collection module includes an upper housing with an air guide pipe. The upper and lower ends of the upper housing are connected to the material conveying pipe and the dust collection module, respectively. A pulse airflow generator is connected to the outside of the upper housing. Multiple air conveying pipes that match the pulse airflow generator are installed inside the upper housing. A sealing baffle with multiple dust suction columns is installed on the inner wall of the upper housing. Multiple air jets that match the dust suction columns are installed on the pulse airflow generator.

[0009] The conveying pipe includes a fixed pipe connected to the upper housing, an intermediate pipe connected between the fixed pipe and the sealing partition, a movable pipe slidably connected to the bottom end of the intermediate pipe, and a piston pipe connected to the bottom end of the movable pipe.

[0010] The dust extraction module includes a lower housing connected to the mounting bracket, an inner guide cone connected to the upper housing inside the lower housing, and multiple ventilation holes at the upper end of the inner guide cone, with ventilation plates installed inside the ventilation holes;

[0011] The ventilation panel includes a grille ventilation panel installed on the outside of the ventilation hole, and a grille baffle that matches the grille ventilation panel is provided on the inside of the ventilation hole. Multiple electric push rods are connected between the grille baffle and the lower housing. Both the grille ventilation panel and the grille baffle are grille panels, and the grilles on the grille ventilation panel and the grille baffle are staggered. When the grille ventilation panel and the grille baffle overlap, the grilles on the grille baffle close the grille holes on the grille ventilation panel.

[0012] The bottom of the lower housing is connected to multiple circumferentially distributed on / off valves. The multiple on / off valves are connected by an outer bellows, which communicate with the inner cavity of the lower housing. The bottom of the lower housing is provided with a discharge hole that matches the piston tube, and the discharge hole is located between the multiple on / off valves. The outer bellows is provided with an inner bellows that matches the outer bellows, and the top of the inner bellows is equipped with a mating ring that matches the piston tube.

[0013] In the aforementioned bulk loader equipped with a dust collection module, it is convenient to collect and retransport the dust generated during material conveying.

[0014] As a further improvement of this application, the inner guide cone is conical, and the bottom end of the inner guide cone matches the discharge hole, with the opening and closing valve located on the outside of the inner guide cone.

[0015] As a further improvement of this application, an air intake pipe is installed at the lower end of the lower housing, and an air guide ring that matches the air intake pipe is installed inside the lower housing, with multiple nozzles provided on the air guide ring.

[0016] As a further improvement to this application, multiple airflow sensors that match the suction column are installed on the sealing partition.

[0017] As another improvement of this application, the suction column includes a fixed frame fixedly connected to the sealing partition, a dust collection bag is sleeved on the fixed frame, and an airflow sensor is installed at the output end of the suction column.

[0018] As another improvement of this application, the intermediate tube includes a protective shell installed between the upper housing and the sealing partition, a movable tube passing through the intermediate tube and slidably connected to the fixed tube, and a plurality of cylinders installed inside the intermediate tube, with the working end of the cylinders fixedly connected to the outer wall of the movable tube.

[0019] As another improvement of this application, it also includes an ash collection control system, which includes a controller mounted on a mounting frame. The controller is connected to a data processing module and a monitoring module. Multiple airflow sensors are connected to the monitoring module. A fan that matches the air intake pipe and the air guide pipe is mounted on the mounting frame. The fan, cylinder and pulse airflow generator are all connected to the controller via signals. The controller is equipped with a desorption mode.

[0020] As a further improvement to this application, when the monitoring module detects that the airflow velocity detected by more than a set number of airflow sensors has decreased to the set value, the controller starts the desorption mode. When the desorption mode is working, the cylinder in the intermediate tube works, driving the movable tube to rise, causing the piston tube to separate from the inner bellows. Then the pulse airflow generator works, causing the air delivery pipe to output pulse airflow. At this time, the particles absorbed by the dust collection bag on the dust collection column are desorbed by the impact of the airflow. The particles on the dust collection bag fall to the bottom of the guide cone and into the inner bellows. At this time, the fan is turned on, causing the air delivery pipe to input auxiliary airflow into the upper housing. At this time, the particles desorbed on the dust collection column are concentrated and output through the inner bellows.

[0021] In summary, this method facilitates the centralized collection of dust during material conveying, monitors the collection process, and allows for the convenient re-conveyance of collected particles once the set amount of dust has been collected, thus achieving centralized and automated dust recycling and re-discharge.

Detailed Implementation

[0032] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0033] First implementation method:

[0034] Figures 1-6 A bulk loading machine with a dust collection module is shown, including a mounting frame 1, a dust collection module 2 connected to the mounting frame 1, and a material conveying pipe 3 and a dust extraction module 4 respectively connected to the upper and lower ends of the dust collection module 2.

[0035] The dust collection module 2 includes an upper housing 201 with an air guide pipe. The upper and lower ends of the upper housing 201 are connected to the material conveying pipe 3 and the dust collection module 4, respectively. A pulse airflow generator 202 is connected to the outside of the upper housing 201. Multiple air conveying pipes 203 that match the pulse airflow generator 202 are installed inside the upper housing 201. A sealing partition 204 with multiple suction columns 205 is installed on the inner wall of the upper housing 201. Multiple air jets that match the suction columns 205 are installed on the pulse airflow generator 202. The input end of the suction column 205 is located on the upper side of the sealing partition 204. Multiple airflow sensors that match the suction column 205 are installed on the sealing partition 204. The suction column 205 includes a fixed frame that is fixedly connected to the sealing partition 204. A dust collection bag is sleeved on the fixed frame. The airflow sensors are installed at the output end of the suction column 205.

[0036] The conveying pipe 3 includes a fixed pipe 301 connected to the upper housing 201, an intermediate pipe 302 connected between the fixed pipe 301 and the sealing partition 204, a movable pipe 303 slidably connected to the bottom end of the intermediate pipe 302, and a piston pipe connected to the bottom end of the movable pipe 303.

[0037] The intermediate tube 302 includes a protective shell installed between the upper housing 201 and the sealing partition 204. The movable tube 303 passes through the intermediate tube 302 and is slidably connected to the fixed tube 301. Multiple cylinders are installed inside the intermediate tube 302, and the working end of the cylinder is fixedly connected to the outer wall of the movable tube 303.

[0038] The dust extraction module 4 includes a lower housing 401 connected to the mounting bracket 1. An inner guide cone 402 connected to the upper housing 201 is connected inside the lower housing 401. Multiple ventilation holes are opened at the upper end of the inner guide cone 402, and a ventilation plate 7 is installed inside the ventilation holes.

[0039] The bottom of the lower housing 401 is connected to multiple circumferentially distributed on / off valves 403. The inner guide cone 402 is conical, and its bottom end matches the discharge hole. The on / off valves 403 are located on the outside of the inner guide cone 402. An air intake pipe is installed at the lower end of the lower housing 401, and an air guide ring matching the air intake pipe is installed inside the lower housing 401. Multiple nozzles are provided on the air guide ring. When it is necessary to stop the dust introduction, the multiple on / off valves 403 can be closed. At this time, the air guide ring outputs airflow, so that the dust in the lower housing 401 and the inner guide cone 402 continues to be transported to the dust collection module 2, so as to empty the dust retained in the dust introduction module 4.

[0040] Multiple on / off valves 403 are connected by an outer bellows 5, and the outer bellows 5 communicates with the inner cavity of the lower housing 401. The bottom end of the lower housing 401 is provided with a discharge hole that matches the piston tube, and the discharge hole is located between the multiple on / off valves 403. The outer bellows 5 is provided with an inner bellows 6 that matches the outer bellows 5, and the top end of the inner bellows 6 is equipped with a mating ring that matches the piston tube.

[0041] During operation, this solution conveys materials through the conveying pipe 3 to the inner corrugated pipe 6, allowing the material to be transported to the tank truck. Dust generated during the material discharge process through the inner corrugated pipe 6 is collected through the outer corrugated pipe 5. The dust is then guided to the dust collection module 2 by the fan. The dust is intercepted by the dust collection column 205 inside the dust collection module 2, and the dust is adsorbed by the dust collection bag on the dust collection column 205, thus achieving centralized collection of dust during material transportation.

[0042] Second implementation method:

[0043] Figures 2-8As shown, the ventilation plate 7 includes a grille ventilation plate 701 installed on the outside of the ventilation hole, and a grille baffle 702 matching the grille ventilation plate 701 is provided on the inside of the ventilation hole. A plurality of electric push rods 703 are connected between the grille baffle 702 and the lower housing 401. Both the grille ventilation plate 701 and the grille baffle 702 are grille plates. The grilles on the grille ventilation plate 701 and the grille baffle 702 are staggered. When the grille ventilation plate 701 and the grille baffle 702 overlap, the electric push rods 703 and the grilles on the grille baffle 702 close the grille holes on the grille ventilation plate 701.

[0044] It also includes an ash collection control system, which includes a controller installed on the mounting frame 1. The controller is connected to a data processing module and a monitoring module. Multiple airflow sensors are connected to the monitoring module. A fan that matches the air intake pipe and the air guide pipe is installed on the mounting frame 1. The fan, cylinder and pulse airflow generator 202 are all connected to the controller signal.

[0045] During the process of suction column 205, airflow sensor monitors the change in airflow velocity at suction column 205. When the airflow velocity detected by more than a set number of airflow sensors decreases to the set value, the feed pipe 3 stops feeding. At this time, the gate valve at the upper end of feed pipe 3 is closed, and the grid ventilation plate 701 and grid baffle 702 are closed. The controller starts the desorption mode.

[0046] When the desorption mode is in operation, the cylinder inside the intermediate pipe 302 operates, driving the movable pipe 303 to rise, causing the piston pipe to separate from the inner bellows 6. Then, the pulse airflow generator 202 operates, causing the air delivery pipe 203 to output pulse airflow. At this time, the particles absorbed by the dust collection bag on the dust collection column 205 are desorbed by the impact of the airflow. The particles on the dust collection bag fall to the bottom of the guide cone 402 and into the inner bellows 6. At this time, the fan is turned on, so that the air guide pipe on the upper housing 201 inputs auxiliary airflow A into the upper housing 201. At this time, the desorbed particles on the dust collection column 205 are concentrated and output through the inner bellows 6. At this time, the fan can also be turned on to output auxiliary airflow B to the air guide ring at the bottom of the lower housing 401. The output auxiliary airflow B is input into the outer bellows 5, so that the outer bellows 5 synchronously delivers airflow, making it difficult for the conveyed dust to flow back through the outer bellows 5.

[0047] This embodiment presets a flow threshold at the output end of the dust collector bag. When the output airflow is lower than the flow threshold, the equipment stops material conveying and performs dust desorption. After desorption, the dust particles are output again through the inner corrugated pipe 6. This makes it easy to ensure that the dust collection module 2 is not easily blocked due to excessive dust adsorption during the process of conveying a large amount of material, and it is also convenient to concentrate the adsorbed dust and output it to the equipment loaded with material.

[0048] In summary, this method facilitates the centralized collection of dust during material conveying, monitors the collection process, and allows for the convenient re-conveyance of collected particles once the set amount of dust has been collected, thus achieving centralized and automated dust recycling and re-discharge.

[0049] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
