Description

Technical Field

[0001] The present application relates to the field of dust reduction systems, and in particular to a dust reduction system for a powder storage workshop. Background Art

[0002] Cement: A powdered, hydraulic, inorganic cementitious material. When mixed with water, it forms a slurry that hardens in air or water, firmly binding materials like sand and stone. Early lime and volcanic ash mixtures are very similar to modern lime-pozzolana cement, used to bind crushed stone concrete. After hardening, it not only offers high strength but also resists erosion by fresh or salt water. For a long time, it has been used as an important cementitious material in civil engineering, water conservancy, and national defense projects. Cement was formerly known as "cement."

[0003] The powder storage room is where cement raw materials are stored. Powder materials are typically covered with a cloth to minimize dust generation. However, during powder transportation or other processes where the cloth needs to be lifted, dust is easily generated in the powder storage room, requiring a dust collection system to remove the dust.

[0004] The dust collection system consists of a dust collection pipe installed in the powder storage room. One end of the dust collection pipe extends out of the powder storage room and is connected to a bag dust collector or other dust collection device. The other end is equipped with a dust collection head. However, as the dust collection workload accumulates, the dust collection head may become clogged, resulting in low dust collection efficiency. Summary of the Invention

[0005] In order to ensure the dust removal efficiency of the powder storage workshop, the present application provides a dust reduction system for the powder storage workshop.

[0006] The dust suppression system for a powder storage workshop provided in this application adopts the following technical solution: A dust reduction system for a powder storage workshop, which is arranged inside the powder storage room, includes a dust exhaust pipe fitting, the dust exhaust pipe fitting includes a dust suction head with an open end, a receiving mechanism is installed in the powder storage room, the receiving mechanism includes an auxiliary pipe with a hollow structure, a receiving port is provided on a surface of the auxiliary pipe close to the dust suction head, the dust suction head abuts against one side wall of the auxiliary pipe and the dust suction head is connected to the inside of the auxiliary pipe through the receiving port, a ventilation pipe is installed on the auxiliary pipe, a ventilation port is provided at one end of the ventilation pipe away from the auxiliary pipe, a wind wheel is rotatably connected in the ventilation pipe, a wind wheel shaft is fixedly connected to the middle of the wind wheel, one end of the wind wheel shaft passes through the auxiliary pipe and extends out of the auxiliary pipe, and an elastic plate is fixedly connected to the end of the wind wheel shaft extending out of the auxiliary pipe, and one end of the elastic plate contacts the side wall of the corresponding dust suction head.

[0007] By adopting the above technical solution, the dust in the powder storage workshop can be effectively collected and discharged. Specifically, the cooperative design between the dust suction head and the auxiliary pipe ensures the smooth entry of dust. The dust enters the ventilation pipe and the auxiliary pipe along the ventilation port, then enters the dust removal head, and is discharged along the dust discharge pipe fitting. During this process, the wind wheel structure in the ventilation pipe rotates under the action of the air flow, driving the wind wheel shaft and the elastic plate to rotate. The rotation of the elastic plate can strike the dust suction head, thereby forming a dynamic cleaning effect on the dust suction head, reducing the probability of dust clogging at the dust suction head, ensuring the dust removal efficiency of the powder storage workshop. At the same time, after the dust knocked off from the dust suction head falls into the auxiliary pipe, it is sucked in by the dust suction head again and discharged, limiting the situation where the dust knocked off from the dust suction head scatters into the powder storage workshop.

[0008] Preferably, the dust discharge pipe fitting includes two main pipes and multiple pairs of branch pipes fixedly connected between the two main pipes. Each branch pipe is fixedly connected with a plurality of dust suction heads. One of the main pipes is fixedly connected and communicated with a main pipe. One end of the main pipe extends out of the powder storage room, and an exhaust fan is installed on the main pipe.

[0009] By adopting the above technical solution, a plurality of dust suction heads are distributed on the branch pipes, ensuring the comprehensive coverage and absorption of dust in each area of the workshop. The branch pipes are connected to the main pipes, and the collected dust is discharged outside the powder storage room through the main pipe. The setting of the exhaust fan further enhances the dust discharge efficiency, making the entire dust removal process more stable and reliable.

[0010] Preferably, a driving mechanism is installed between each pair of branch pipes. The driving mechanism includes two hydraulic cylinders. The piston rods of the two hydraulic cylinders are both arranged downward, and a rotating shaft is rotatably connected between them. Each rotating shaft is fixedly connected with a plurality of auxiliary pipes. Two ventilation ports are opened on each auxiliary pipe, and each ventilation port corresponds to a dust suction head on one of the branch pipes. The driving mechanism also includes a driving motor for driving the rotating shaft to rotate.

[0011] By adopting the above technical solution, when the dust suction head does not need to be dredged, the auxiliary pipe can be stored. Start the two hydraulic cylinders at the same time, so that the hydraulic cylinders drive the rotating shaft and the plurality of auxiliary pipes to descend, and the auxiliary pipe disengages from the dust removal head. Then start the driving motor to drive the rotating shaft to rotate. The rotating shaft drives the plurality of auxiliary pipes to rotate until the auxiliary pipe is vertically arranged. Then start the hydraulic cylinder to drive the rotating shaft and the plurality of auxiliary pipes to rise until the rotating shaft and the plurality of auxiliary pipes are stored between a pair of branch pipes. At this time, the auxiliary pipe rotates to a non-working position, realizing the storage of the auxiliary pipe, reducing the situation that the auxiliary pipe occupies extra space in the non-working state, and improving the space utilization rate and operation convenience of the system.

[0012] Preferably, a filter screen plate is fixedly connected at each ventilation port.

[0013] By adopting the above technical solution, the filter screen plate can effectively block larger particulate matters from entering the ventilation pipe, reduce the occurrence of blockage in the auxiliary pipe, limit the situation where larger particulate matters affect the rotation of the wind wheel, and thus ensure the normal operation of the dust removal system.

[0014] Preferably, a vibration motor is fixedly connected to the dust exhaust pipe fitting.

[0015] By adopting the above technical solution, a vibration motor is fixedly connected to the dust exhaust pipe fitting, which can effectively reduce the accumulation and blockage of powder materials inside the dust exhaust pipe fitting, thereby improving the dust exhaust efficiency and reliability of the entire dust removal system.

[0016] Preferably, a reinforcement mechanism for fixedly connecting the dust exhaust pipe fitting to the powder storage workshop is connected to the dust exhaust pipe fitting. The reinforcement mechanism includes a connecting rod one fixedly connected to the dust exhaust pipe fitting, and also includes a connecting rod two fixedly connected to the top plate of the powder storage workshop. A spring is fixedly connected between the connecting rod one and the connecting rod two.

[0017] By adopting the above technical solution, the dust exhaust pipe fitting is fixedly connected to the top plate of the powder storage workshop through the reinforcement mechanism, and the connecting rod one and the connecting rod two are fixedly connected by a spring. This structure can effectively buffer the shaking of the dust exhaust pipe fitting caused by vibration or external force during the working process, improve the stability of the system, reduce the situation of loosening or damage of the dust exhaust pipe fitting due to long-term use, and thus ensure the normal operation of the dust removal system. The setting of the spring can also absorb part of the vibration energy, reduce noise, and improve the overall dust removal effect.

[0018] Preferably, a flange is fixedly connected to the connecting rod one, and a flange is also fixedly connected to the connecting rod two. A plurality of bolts are installed between the two flanges, and each bolt sequentially passes through the two flanges and is threadedly connected with a nut.

[0019] By adopting the above technical solution, the use of the flange increases the connection area and improves the connection stability, while the cooperation of a plurality of bolts further enhances the connection reliability, effectively restricting the situation of loosening or falling off of the dust exhaust pipe fitting during the working process. This connection method is not only convenient for installation and disassembly, but also can adapt to different installation environments to ensure the normal operation of the dust removal system.

[0020] Preferably, the open end of the dust suction head is a flared opening.

[0021] By adopting the above technical solution, the open end of the dust suction head is designed in a flared shape, which can effectively increase the air intake range of the dust suction head, thereby improving the collection efficiency of dust in the powder storage workshop. The flared opening design enables the dust suction head to cover a larger area during the working process, reduce dust leakage, and improve the overall dust removal effect.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. Reduce the probability of dust clogging at the dust suction head, and ensure the dust removal efficiency in the powder storage workshop; 2. Facilitate the storage of the auxiliary pipe, and reduce the occurrence of the auxiliary pipe occupying extra space in the non-working state; 3. The setting of the spring can also absorb part of the vibration energy, reduce noise, and improve the overall dust reduction effect. Description of the Drawings

Detailed Embodiment

[0028] The following further describes the present application in detail with reference to the attached Figures 1-4 drawings.

[0029] An embodiment of the present application discloses a dust reduction system for a powder storage workshop. Referring to Figure 1 and Figure 2 , it is arranged in the powder storage workshop. The dust reduction system includes a dust exhaust pipe fitting 1, and the dust exhaust pipe fitting 1 includes two main pipes 11 and multiple pairs of branch pipes 12. The multiple pairs of branch pipes 12 are fixedly connected between the two main pipes 11. Each branch pipe 12 is fixedly connected with a plurality of downwardly arranged dust suction heads 13, and the lower end of the dust suction head 13 is open. One of the main pipes 11 is fixedly connected and communicated with a main duct 14, and one end of the main duct 14 away from the main pipe 11 penetrates through the side wall of the powder storage workshop and extends to the outside of the powder storage workshop. A suction pump is installed on the main duct 14, and one end of the main duct 14 is connected to a bag filter or other dust collection device.

[0030] Start the exhaust pump. At this time, the dust in the powder storage workshop is discharged along the dust collection head 13, the branch pipe 12, the main pipe 11, and the main pipe 14, which is relatively simple and convenient for dust removal.

[0031] Reference Figure 2 and Figure 3 The opening end of each dust collecting head 13 is designed to be expanded, and the expansion shape can be trumpet-shaped or conical to increase the suction area and improve the dust collection efficiency.

[0032] To facilitate unclogging of the vacuum heads 13, a connecting mechanism 2 is installed between the two branch pipes 12 in each pair of branch pipes 12. The connecting mechanism 2 includes a rotating shaft 21 and multiple auxiliary pipes 22 fixedly connected to the rotating shaft 21. Each auxiliary pipe 22 is arranged perpendicular to the rotating shaft 21, and one auxiliary pipe 22 corresponds to a pair of vacuum heads 13. The rotating shaft 21 is connected to a driving mechanism 3 that drives the rotating shaft 21 to rotate and vertically lift.

[0033] The auxiliary tube 22 is a hollow structure, and two vents 221 are provided on one long sidewall of the auxiliary tube 22. One vent 221 corresponds to one vacuum head 13, and the vacuum head 13 contacts the outer wall of the auxiliary tube 22 and communicates with the interior of the auxiliary tube 22 through the vents 221. Two vent pipes 23 are fixedly connected to a sidewall of the auxiliary tube 22 facing away from the vents 221. Each vent pipe 23 is open at one end away from the auxiliary tube 22. Each vent pipe 23 is provided with a wind wheel 24. A wind wheel shaft 25 is fixedly connected to the middle of the wind wheel 24, and the wind wheel shaft 25 is rotatably connected to a sidewall of the auxiliary tube 22. The end of the wind wheel shaft 25 closest to the vacuum head 13 passes through the auxiliary tube 22 and is fixedly connected to an elastic sheet 26. The elastic sheet 26 is an eccentric wheel, and one end of the elastic sheet 26 contacts the sidewall of the corresponding vacuum head 13. When the elastic piece 26 rotates, the elastic piece 26 interferes with the dust collector head 13 and is deformed under the pressure of the dust collector head 13 , thereby separating from the dust collector head 13 . During this process, the elastic piece 26 strikes the dust collector head 13 .

[0034] When the cleaner head 13 draws air, the airflow flows along the vent 23 into the auxiliary tube 22, and then into the cleaner head 13. During this process, the wind forces the impeller 24 to rotate. The rotation of the impeller 24 drives the rotation of the shaft 21 and the elastic plate 26. The elastic plate 26 then strikes the cleaner head 13, facilitating the unclogging of the cleaner head 13. Dust that falls from the cleaner head 13 due to vibration enters the auxiliary tube 22 through the vent 221, and then reenters the cleaner head 13 driven by the wind.

[0035] A filter screen 27 is fixedly connected to each vent 221 to prevent larger impurities from entering the auxiliary pipe 22 and the vent pipe 23 and affecting the normal rotation of the wind wheel 24 .

[0036] The driving mechanism 3 includes two hydraulic cylinders 31 fixedly connected to the inner top wall of the powder storage workshop. The piston rods of the two hydraulic cylinders 31 are arranged vertically downward and are respectively fixedly connected with fixing blocks 32. The rotating shaft 21 is rotatably connected between the two fixing blocks 32. A driving motor 33 is fixedly connected to one of the fixing blocks 32, and the output shaft of the driving motor 33 is coaxially fixed to one end of the rotating shaft 21.

[0037] When it is necessary to store the receiving mechanism 2, the two hydraulic cylinders 31 are started simultaneously. The piston rods of the two hydraulic cylinders 31 drive the rotating shaft 21 and the plurality of auxiliary pipes 22 to move downward, and each auxiliary pipe 22 disengages from the corresponding dust suction head 13. Subsequently, the driving motor 33 is started to drive the rotating shaft 21 to rotate, and the rotation of the rotating shaft 21 drives each auxiliary pipe 22 to be in a vertical state. Then the two hydraulic cylinders 31 are started simultaneously, and the piston rods of the two hydraulic cylinders 31 drive the rotating shaft 21 and the plurality of auxiliary pipes 22 to rise and be stored between a pair of branch pipes 12.

[0038] A vibration motor 4 is fixedly connected to the dust exhaust pipe fitting 1. The vibration motor 4 removes the dust adhering to the inner wall of the pipe through high-frequency vibration, reducing the occurrence of blockage.

[0039] Refer to Figure 3 and Figure 4 As shown in, four reinforcing mechanisms 5 for connecting the dust exhaust pipe fitting 1 with the powder storage workshop are connected to the dust exhaust pipe fitting 1. Each reinforcing mechanism 5 includes a connecting rod 51 and a connecting rod 52. The lower end of the connecting rod 51 is fixedly connected to the dust exhaust pipe fitting 1, and the top end of the connecting rod 52 is fixedly connected to the inner top wall of the powder storage workshop. A spring 53 is provided between the connecting rod 51 and the connecting rod 52. One end of the spring 53 is fixedly connected to the connecting rod 51, and the other end is fixedly connected to the connecting rod 52. The spring 53 plays a buffering role, reducing the occurrence of damage to the dust exhaust pipe fitting 1 due to vibration or external force. The material of the spring 53 can be selected as high-strength steel wire, which has good elasticity and durability.

[0040] Flange plates 54 are fixedly connected to the mutually approaching ends of the connecting rod 51 and the connecting rod 52. A plurality of bolts 55 are provided between the two flange plates 54. Each bolt 55 sequentially passes through the two flange plates 54 and is threadedly connected with a nut 56. The nut 56 abuts against one of the flange plates 54, and the cap at one end of the bolt 55 abuts against the other flange plate 54.

[0041] In order to reduce the damage caused by vibration to the main pipe 14, the main pipe 14 is a corrugated pipe.

[0042] The implementation principle of a dust reduction system for a powder storage workshop in an embodiment of this application is as follows: When it is necessary to clean the dust suction head 13, each pair of hydraulic cylinders 31 is started simultaneously, so that the piston rod of the hydraulic cylinder 31 drives the rotating shaft 21 and the auxiliary pipe 22 to descend. Subsequently, the driving motor 33 is started, and the driving motor 33 drives the rotating shaft 21 and a plurality of auxiliary pipes 22 to rotate until each auxiliary pipe 22 is horizontally arranged. Then each pair of hydraulic cylinders 31 is started to drive the rotating shaft 21 and the auxiliary pipe 22 to rise until each air vent 221 on the auxiliary pipe 22 is communicated with the dust suction head 13 and the auxiliary pipe 22 abuts against the dust suction head 13. At this time, the exhaust fan is started, and the dust exhaust pipe fitting 1 can continue to suck dust. At the same time, the wind wheel 24 drives the wind wheel shaft 25 and the elastic plate to rotate, and the elastic plate knocks on the dust suction head 13 to clean the dust suction head 13.

[0043] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
