Compared with the prior art, the invention adopts the coordinated use of a telescopic rod and a motor, so that the uniform distribution head can be telescopically rotated, so that when the material is loaded into the ash loading compartment, the centrifugal force of the uniform distribution head is used to scatter the material to the surroundings, so that the material box can be fully loaded, and the problem that the straight-falling material enters the ash loading compartment and accumulates into a triangle, and the two sides of the upper part of the ash loading compartment cannot be loaded with material, is solved, and the material loading capacity of the equipment is increased, thereby accelerating the unloading speed of the equipment for the material in the warehouse.

[0012] The bottom end of the lower shell is connected to multiple circumferentially distributed opening and closing valves, an outer bellows is connected between the multiple opening and closing valves, and the outer bellows is communicated with the inner cavity of the lower shell, a discharge hole matching the piston tube is opened at the bottom end of the lower shell, and the discharge hole is located between the multiple opening and closing valves, an inner bellows matching the outer bellows is arranged inside the outer bellows, and a docking ring matching the piston tube is installed at the top end of the inner bellows.

DETAILED DESCRIPTION

[0032] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0033] The first implementation method:

[0034] Figure 1-Figure 6 A bulk loader with a dust collecting module is shown, comprising a mounting frame 1, a dust collecting module 2 is connected to the mounting frame 1, and a material conveying pipe 3 and a dust collecting module 4 are connected to the upper and lower ends of the dust collecting module 2 respectively;

[0035] The dust collecting module 2 includes an upper shell 201 with an air duct, the upper and lower ends of the upper shell 201 are respectively connected to the feeding pipe 3 and the dust collecting module 4, the outside of the upper shell 201 is connected to a pulse airflow generator 202, a plurality of air delivery pipes 203 matching the pulse airflow generator 202 are installed in the upper shell 201, a sealing baffle 204 with a plurality of dust suction columns 205 is installed on the inner wall of the upper shell 201, and a plurality of air jets matching the dust suction columns 205 are installed on the pulse airflow generator 202; the input end of the dust suction column 205 is located on the upper side of the sealing baffle 204, a plurality of airflow sensors matching the dust suction column 205 are installed on the sealing baffle 204, the dust suction column 205 includes a fixed frame fixedly connected to the sealing baffle 204, a dust bag is sleeved on the fixed frame, and the airflow sensor is installed at the output end of the dust suction column 205.

[0036] The material delivery pipe 3 includes a fixed pipe 301 connected to the upper shell 201, an intermediate pipe 302 is connected between the fixed pipe 301 and the sealing partition 204, a movable pipe 303 is slidably connected to the bottom end of the intermediate pipe 302, and a piston pipe is connected to the bottom end of the movable pipe 303;

[0037] The intermediate tube 302 includes a protective shell installed between the upper shell 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. A plurality of cylinders are installed in the intermediate tube 302, and the working ends of the cylinders are fixedly connected to the outer wall of the movable tube 303.

[0038] The dust collecting module 4 comprises a lower shell 401 connected to the mounting frame 1, an inner guide cone 402 connected to the upper shell 201 is connected to the lower shell 401, a plurality of ventilation holes are formed at the upper end of the inner guide cone 402, and a vent plate 7 is installed in the ventilation holes;

[0039] The bottom of the lower shell 401 is connected to a plurality of opening and closing valves 403 distributed in a circle, the inner guide cone 402 is conical, and the bottom of the inner guide cone 402 matches the discharge hole, and the opening and closing valves 403 are located on the outside of the inner guide cone 402. An air duct is installed at the lower end of the lower shell 401, and an air guide ring matching the air duct is installed inside the lower shell 401, and a plurality of nozzles are arranged on the air guide ring; when it is necessary to stop the introduction of dust, the plurality of opening and closing valves 403 can be closed, and at this time, the air guide ring outputs airflow, so that the dust in the lower shell 401 and the inner guide cone 402 continues to be transported to the dust collecting module 2, so as to empty the dust retained in the dust collecting module 4;

[0040] An outer bellows 5 is connected between the multiple opening and closing valves 403, and the outer bellows 5 is communicated with the inner cavity of the lower shell 401. A discharge hole matching the piston tube is opened at the bottom end of the lower shell 401, and the discharge hole is located between the multiple opening and closing valves 403. An inner bellows 6 matching the outer bellows 5 is arranged inside the outer bellows 5, and a docking ring matching the piston tube is installed at the top end of the inner bellows 6.

[0041] When this scheme is working, materials are fed to the inner bellows 6 through the feed pipe 3, so that the logistics is transported to the tank truck through the inner bellows 6, and the dust generated during the discharge of materials from the inner bellows 6 is recovered through the outer bellows 5. The dust is guided to the dust collecting module 2 under the action of the fan, and the dust is intercepted by the dust collection column 205 in the dust collecting module 2, and the dust is adsorbed by the dust removal bag on the dust collection column 205, so as to realize the centralized recovery of dust during material transportation.

[0042] The second implementation method:

[0043] Figure 2-Figure 8As shown, the ventilation plate 7 includes a grille ventilation plate 701 installed on the outside of the ventilation hole, a grille baffle 702 matching the grille ventilation plate 701 is provided on the inside of the ventilation hole, and a plurality of electric push rods 703 are connected between the grille baffle 702 and the lower shell 401; the grille ventilation plate 701 and the grille baffle 702 are both grille plates, and the grilles on the grille ventilation plate 701 and the grille baffle 702 are staggered, and when the grille ventilation plate 701 and the grille baffle 702 overlap, the electric push rod 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 a mounting frame 1, to which a data processing module and a monitoring module are connected, and multiple airflow sensors are connected to the monitoring module. A fan matching the air duct and the air guide duct is installed on the mounting frame 1, and the fan, cylinder and pulse airflow generator 202 are all connected to the controller signal.

[0045] During the dust collection process of the dust collection column 205, the air flow sensor monitors the flow rate change of the exhaust air flow at the dust collection column 205. When the air flow rates detected by the air flow sensors exceeding the set number are all reduced to the set value, the material delivery pipe 3 stops delivering materials. At this time, the gate valve at the upper end of the material delivery pipe 3 is closed, and the grid air permeable plate 701 and the grid baffle 702 are closed at the same time; the controller starts the desorption mode;

[0046] When the desorption mode is working, the cylinder in the middle tube 302 works to drive the movable tube 303 to rise, so that the piston tube is separated from the inner bellows 6, and then the pulse airflow generator 202 works to make the air supply pipe 203 output a pulse airflow. At this time, the particles absorbed by the dust bag on the dust collection column 205 are desorbed by the impact of the airflow. At this time, the particles on the dust collection bag fall to the bottom end of the guide cone 402 and fall into the inner bellows 6. At this time, the fan is turned on to make the air guide pipe on the upper shell 201 input auxiliary airflow A into the upper shell 201. At this time, the particles desorbed from the dust collection column 205 are concentratedly 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 shell 401, and the output auxiliary airflow B is input into the outer bellows 5, so that the outer bellows 5 synchronously conveys the airflow, so that the conveyed dust is not easy to flow back through the outer bellows 5.

[0047] The present embodiment presets a flow threshold value at the output end of the dust removal bag. When the output air flow rate is lower than the flow threshold value, the device stops material transportation and performs dust desorption. After desorption, the dust particles are output again through the inner bellows 6. This makes it easy to ensure that the dust collection module 2 is not easily blocked due to excessive dust adsorption during the transportation of large amounts of materials, and facilitates the concentrated adsorbed dust to be output to the equipment for loading materials.

[0048] To sum up, it is convenient to collect the dust during feeding and monitor the collection process. After the dust is collected to a set amount, the collected particles can be transported centrally again to realize the centralized recovery and automatic discharge of dust.

[0049] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
