Description

Technical Field

[0001] The invention relates to the field of iron ore powder processing, and in particular to a hopper with an anti-blocking structure for iron ore powder processing. Background Art

[0002] Iron ore powder processing is a basic link in the metallurgical and chemical industries. In industrial production, powder and fine granular materials are often packaged. The upper part of the packaging machine mostly uses a conical hopper. However, the characteristics of powder are that it is easy to arch and stick, which causes poor packaging and material discharge. It is necessary to manually knock on the hopper to assist the material discharge operation.

[0003] With the advancement of industrialization, the demand for efficient and reliable material handling equipment will continue to grow. Enterprises have higher and higher requirements for equipment performance. The existing conical hopper + manual assisted material discharge operation can no longer meet the needs of use. Therefore, it is necessary to develop a new type of hopper with anti-blocking structure for iron ore powder processing to improve efficiency. Summary of the invention

[0004] Purpose of the invention: In view of the shortcomings and defects of the prior art, the present invention provides a hopper with an anti-blocking structure for processing iron ore powder, which solves the problem that traditional hoppers are prone to blockage when processing iron ore powder and other materials that are easy to agglomerate and adhere, improves the fluidity of the hopper, reduces downtime, improves production efficiency, reduces maintenance costs, and reduces the labor and time costs of staff.

[0005] Technical solution: The present invention provides a hopper with an anti-blocking structure for processing iron ore powder, which is characterized by comprising a hopper body, the hopper body being provided with a plurality of limit columns, a PLC controller being provided outside the hopper body, a mounting frame being provided on the top surface of the hopper body, sliding holes being provided at four corners of the top surface of the mounting frame, and the sliding holes being slidably connected to the limit columns; a plurality of connecting plates being fixed inside the mounting frame, the bottom surface of the connecting plates being rotatably connected to a push plate through hinges, and a pressing column being fixed on one side of the push plate; a plurality of mounting grooves being provided on the top surface of the hopper body, a cylinder being fixed on the inner wall of the mounting groove, the cylinder being electrically connected to the PLC controller, and one end of the telescopic rod of the cylinder being fixedly connected to the bottom surface of the mounting frame; mounting holes are provided on both sides of the rear end of the hopper body, a flow detector is fixed on the inner wall of the mounting hole on the right side, and the flow detector is electrically connected to the PLC controller.

[0006] Among them, the number of the limit columns is 4, and the 4 limit columns are located at the 4 corners of the top surface of the hopper body.

[0007] When in use, the cylinder and the push plate cooperate to push the material regularly or as needed when the iron ore powder is discharged to prevent the material from forming dead corners or accumulation in the hopper body, thereby avoiding blockage. The flow detector monitors the flow of materials in the hopper body in real time and feeds the data back to the control system. When the material flow is too low or too high, the flow detector sends a warning signal, and the control system adjusts the working state of the cylinder according to the signal, adjusts the pushing frequency and strength of the push plate, and maintains normal material flow.

[0008] Among them, a pressing column is fixed on one side of the pushing plate, and a fixing groove is opened on the other side of the pushing plate, which extends into the pressing column. A scraper plate is slidably arranged on the inner wall of the fixing groove. The front section of the scraper plate is made of rubber material, and a spring is fixed on one side of the scraper plate, and the other end of the spring is fixed to the inner wall of the fixing groove; an air blowing pipe is fixed to the inner wall of the mounting hole on the left side, and the air blowing pipe extends into the hopper body. A vibration motor is fixed to the outer wall of the tail end of the hopper body, and the vibration motor is electrically connected to the PLC controller.

[0009] When in use, the iron ore powder attached to the inner wall of the hopper body is scraped off by the cooperation of the scraper plate and the spring when the mounting frame moves up and down, so as to prevent the iron ore powder from adhering to the inner wall of the hopper body during the discharge process, so that the iron ore powder can be discharged through the hopper body, thereby improving the discharge speed of the iron ore powder and ensuring the neatness of the inner wall of the hopper body 2; it is connected to the air pump through the air blowing pipe, and when the flow detector detects that the flow rate of the material in the hopper body is too large, the flow detector transmits the signal to the air pump through the PLC controller, so that the air pump fills the material with air through the air blowing pipe, so that the gap between the materials becomes larger, and the accumulation of the materials is prevented; at the same time, when the flow rate of the material in the hopper body is too large, the vibration frequency of the outer wall of the hopper body is increased by the vibration motor, thereby driving the material to move, and preventing the material from agglomerating in the hopper body.

[0010] Among them, a limiting block is fixed on the top of the limiting column, and several mounting plates are fixed on the outer wall of the hopper body. Positioning holes are opened on the top surface of the mounting plates, and fixing bolts are slidably arranged on the inner wall of the positioning holes. The mounting plates are installed by threaded connection or hanging rope connection.

[0011] When in use, the installation frame is blocked by the limit block to prevent the cylinder from moving excessively and causing the installation frame to fall off, making the installation frame more stable during the movement; through the cooperation of the mounting plate and the fixing bolts, the staff fixes the hopper body in the designated position; the staff flexibly adjusts the installation method according to the installation environment of the hopper body.

[0012] Among them, a plurality of load-bearing blocks are fixed on the outer wall of the rear end of the hopper body, through holes are opened on the top surfaces of the load-bearing blocks, and a plurality of inclined grooves are opened on the inner wall of the hopper body.

[0013] When in use, the tail end of the hopper body is limited and fixed by the load-bearing block to stabilize the hopper body, thereby preventing the tail end of the hopper body from swinging, thereby increasing the feeding speed of the iron ore powder; the iron ore powder is guided by the chute when it contacts the inner wall of the hopper body, so that the iron ore powder can perform free fall when it contacts the inner wall of the hopper body, thereby preventing the iron ore powder from adhering to and accumulating on the inner wall of the hopper body.

[0014] Among them, through the cooperation of the cylinder and the push plate, the space occupied by the hopper is reduced while the material is pushed to move. When the material flow is too low or too high, the flow detector will send out a warning signal in time. The control system adjusts the working state of the cylinder according to these signals, adjusts the pushing frequency and strength of the push plate, and maintains normal material flow.

[0015] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention can push the material regularly or as needed when the iron ore powder is discharged through the cooperation of the cylinder and the push plate, so as to prevent the material from forming a dead angle or piling up in the hopper body, thereby avoiding the occurrence of blockage. Since iron ore powder and other powdery materials are easily blocked in the hopper due to static electricity, humidity, uneven particle size, etc., the movement of the push plate can help the material to be evenly distributed in the hopper, ensuring that the material can be continuously and evenly supplied to the next processing link, avoiding low production efficiency or equipment damage caused by uneven feeding. The flow detector can monitor the flow of materials in the hopper body in real time and feed the data back to the control system. The present invention solves the problem that traditional hoppers are prone to blockage when handling iron ore powder and other materials that are easy to agglomerate and adhere, improves the fluency of the hopper, reduces downtime, improves production efficiency, reduces maintenance costs, and reduces the labor and time costs of staff.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figure 1-Figure 6 As shown, the hopper with an anti-blocking structure for processing iron ore powder of the present invention comprises four limit columns 1, several of the limit columns 1 are respectively fixed at the four corners of the top surface of the hopper body 2, a PLC controller is fixed on the outer wall of the hopper body 2, a mounting frame 3 is provided on the top surface of the hopper body 2, sliding holes 4 are provided at the four corners of the top surface of the mounting frame 3, the sliding holes 4 are slidably connected with the limit columns 1, a plurality of connecting plates 5 are fixed on the inner wall of the mounting frame 3, a push plate 6 is rotatably connected to the bottom surface of the connecting plate 5 through a hinge, a pressing column 7 is fixed on one side of the push plate 6, a plurality of mounting grooves 8 are provided on the top surface of the hopper body 2, a cylinder 9 is fixed on the inner wall of the mounting groove 8, the cylinder 9 is electrically connected to the PLC controller, one end of the telescopic rod of the cylinder 9 is fixed to the bottom surface of the mounting frame 3, mounting holes 10 are provided on the left and right sides of the tail end of the hopper body 2, a flow detector 11 is fixed to the inner wall of the right mounting hole 10, and the cylinder 9 and the flow detector 11 are both electrically connected to the PLC controller.

[0025] During use, through the cooperation of the cylinder 9 and the push plate 6, the material can be pushed regularly or as needed when the iron ore powder is discharged, so as to prevent the material from forming dead corners or accumulation in the hopper body 2, thereby avoiding the occurrence of blockage. Since powdery materials such as iron ore powder are easily affected by static electricity, humidity, uneven particle size, etc. in the hopper, the movement of the push plate 6 can help the material to be evenly distributed in the hopper, ensuring that the material can be continuously and evenly supplied to the next processing link, avoiding low production efficiency or equipment damage caused by uneven feeding. The flow detector 11 can monitor the flow of materials in the hopper body 2 in real time, and feed the data back to the control system. When the material flow is abnormal (such as too low or too high), the flow detector 11 can send out a warning signal in time, and the control system can adjust the working state of the cylinder 9 according to these signals, such as adjusting the pushing frequency and strength of the push plate 6, to maintain normal material flow.

[0026] like Figure 1-Figure 6As shown, a fixing groove 12 is provided on the other side of the push plate 6, and the fixing groove 12 extends into the pressing column 7. A scraper plate 13 is slidably provided on the inner wall of the fixing groove 12. The front section of the scraper plate 13 is made of rubber. A spring 14 is fixed to one side of the scraper plate 13. The other end of the spring 14 is fixed to the inner wall of the fixing groove 12. An air blowing pipe 15 is fixed to the inner wall of the left mounting hole 10. The air blowing pipe 15 extends into the hopper body 2. A vibration motor 16 is fixed to the outer wall of the rear end of the hopper body 2. The vibration motor 16 is electrically connected to the PLC controller.

[0027] In use, through the cooperation of the scraper plate 13 and the spring 14, the iron ore powder attached to the inner wall of the hopper body 2 can be scraped off when the mounting frame 3 moves up and down, preventing the iron ore powder from adhering to the inner wall of the hopper body 2 during the material discharge process, so that the iron ore powder can be discharged smoothly through the hopper body 2, while improving the iron ore powder discharge speed and ensuring the neatness of the inner wall of the hopper body 2. The air pump can be connected to the air pump through the air pipe 15. When the flow detector 11 detects that the flow rate of the material in the hopper body 2 is too large, the flow detector 11 will transmit the signal to the air pump through the PLC controller, so that the air pump will fill the material with air through the air pipe 15, so that the gap between the materials becomes larger, thereby effectively preventing the accumulation of materials. At the same time, when the material flow rate in the hopper body 2 is too large, the vibration motor 16 can increase the vibration frequency of the outer wall of the hopper body 2, thereby driving the material to move and preventing the material from agglomerating in the hopper body 2.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a limiting block 17 is fixed to the top of the limiting column 1, and a plurality of mounting plates 18 are fixed to the outer wall of the hopper body 2. A positioning hole 19 is opened on the top surface of the mounting plate 18, and a fixing bolt 20 is slidably provided on the inner wall of the positioning hole 19. The mounting plate 18 is installed by threaded connection or suspension rope connection.

[0029] In use, the installation frame 3 can be blocked by the stopper 17, which can effectively prevent the cylinder 9 from moving excessively and causing the installation frame 3 to fall off, making the installation frame 3 more stable during movement, thereby ensuring the smooth operation of the hopper body 2, thereby improving the safety of the hopper body 2. Through the cooperation of the mounting plate 18 and the fixing bolts 20, it is convenient for the staff to fix the hopper body 2 in the designated position. At the same time, the staff can flexibly adjust the installation method according to the installation environment of the hopper body 2, so that the hopper body 2 can adapt to different installation environments, thereby improving the adaptability of the hopper body 2.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a plurality of load-bearing blocks 21 are fixed to the outer wall of the rear end of the hopper body 2 , a through hole 22 is formed on the top surface of the load-bearing block 21 , and a plurality of inclined grooves 23 are formed on the inner wall of the hopper body 2 .

[0031] In use, the tail end of the hopper body 2 can be limited and fixed by the load-bearing block 21, making the hopper body 2 more stable, thereby preventing the tail end of the hopper body 2 from swinging, thereby increasing the feeding speed of the iron ore powder, and at the same time, facilitating the installation of the hopper body 2 by the staff. The chute 23 can guide the iron ore powder when it contacts the inner wall of the hopper body 2, so that the iron ore powder can perform free fall when it contacts the inner wall of the hopper body 2, preventing the iron ore powder from adhering to the inner wall of the hopper body 2, thereby improving the practicality of the hopper body 2.

[0032] The present invention can reduce the occupancy of the internal space of the hopper while pushing the material to move through the cooperation between the cylinder and the push plate. When the material flow is abnormal (such as the flow is too low or too high), the flow detector can send out a warning signal in time, and the control system can adjust the working state of the cylinder according to these signals, such as adjusting the pushing frequency and force of the push plate, so as to maintain normal material flow.

[0033] The present invention can push the material regularly or as needed when the iron ore powder is discharged through the cooperation of the cylinder and the push plate, so as to prevent the material from forming a dead angle or piling up in the hopper body, thereby avoiding the occurrence of blockage. Since powdery materials such as iron ore powder are easily blocked in the hopper due to static electricity, humidity, uneven particle size, etc., the movement of the push plate can help the material to be evenly distributed in the hopper, ensuring that the material can be continuously and evenly supplied to the next processing link, avoiding low production efficiency or equipment damage caused by uneven feeding. The flow of the material in the hopper body can be monitored in real time through the flow detector, and the data can be fed back to the control system. The present invention solves the problem that the traditional hopper is prone to blockage when processing materials that are easy to agglomerate and adhere, such as iron ore powder, improves the fluency of the hopper, reduces downtime, improves production efficiency, reduces maintenance costs, and reduces the labor and time costs of staff.
