Description

TECHNICAL FIELD

[0001] The present application relates to the field of iron ore powder processing, and particularly relates to a hopper with anti-blocking structure for iron ore powder processing. BACKGROUND

[0002] Iron ore powder processing is a basic link in the metallurgical, chemical and other industries, and in industrial production, powder and fine particle materials are often packaged, and a conical hopper is often used at the upper part of a packaging machine, but the characteristics of powder are easy to arch and adhere, which causes poor packaging and unloading, and manual knocking of the hopper is required to assist unloading.

[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 the performance of equipment. The existing conical hopper + manual unloading operation cannot meet the needs of use. Therefore, a new hopper with anti-blocking structure for iron ore powder processing needs to be developed to improve efficiency. SUMMARY

[0004] The present application provides a hopper with anti-blocking structure for iron ore powder processing, which solves the problem of blockage of traditional hoppers when processing iron ore powder and other materials that are prone to caking and adhesion, improves the flow of the hopper, reduces downtime, improves production efficiency, reduces maintenance costs, and reduces the labor and time costs of workers.

[0005] Technical scheme: The hopper with anti-blocking structure for iron ore powder processing comprises a hopper body, a plurality of limiting columns are arranged on the hopper body, a PLC controller is arranged outside the hopper body, an installation frame is arranged on the top surface of the hopper body, sliding holes are arranged at the four corners of the top surface of the installation frame, and the sliding holes are in sliding connection with the limiting columns; a plurality of connecting plates are fixedly arranged in the installation frame, the bottom surface of the connecting plate is rotatably connected with a push plate through a hinge, and a pressing column is fixedly arranged on one side of the push plate; a plurality of installation grooves are arranged on the top surface of the hopper body, air cylinders are fixedly arranged on the inner walls of the installation grooves, the air cylinders are electrically connected with the PLC controller, and one end of the extension rod of the air cylinder is fixedly connected with the bottom surface of the installation frame; installation holes are arranged on the left and right sides of the tail end of the hopper body, and a flow detector is fixedly arranged on the inner wall of the installation hole on the right side, and the flow detector is electrically connected with the PLC controller.

[0006] The number of the limiting columns is 4, and the four limiting columns are arranged at the four corners of the top surface of the hopper body.

[0007] In use, through the cooperation of the air cylinder and the pushing plate, the material is pushed periodically or as needed during the discharge of iron ore powder, preventing the formation of dead angles or accumulation of material in the hopper body and avoiding the occurrence of blockage; the flow detector monitors the flow of material in the hopper body in real time and feeds data back to the control system, and 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 air cylinder according to the signal to adjust the pushing frequency and strength of the pushing plate, maintaining normal material flow.

[0008] Wherein, the pushing plate is fixed with a pressing column on one side, and a fixed groove is opened on the other side, the fixed groove extends into the pressing column, a scraping plate is slidably arranged on the inner wall of the fixed groove, the front section of the scraping plate is made of rubber, a spring is fixed on one side of the scraping plate, and the other end of the spring is fixed with the inner wall of the fixed groove; the inner wall of the mounting hole on the left side is fixed with a blowing pipe, the blowing pipe extends into the hopper body, and the outer wall of the tail end of the hopper body is fixed with a vibration motor, and the vibration motor is electrically connected with the PLC controller.

[0009] In use, the cooperation of the scraping plate and the spring can scrape off the iron ore powder adhered to the inner wall of the hopper body when the installation frame moves up and down, preventing 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, improving the discharge speed of the iron ore powder while ensuring the cleanliness of the inner wall of the hopper body 2; the blowing pipe is connected with the air pump, when the flow detector detects that the flow of 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 air into the material through the blowing pipe, so that the gap between the materials becomes larger, preventing the accumulation of materials; at the same time, when the flow of material in the hopper body is too large, the vibration frequency of the outer wall of the hopper body is increased through the vibration motor, so that the material is moved, preventing the material from caking in the hopper body.

[0010] Wherein, the top end of the limiting column is fixed with a limiting block, the outer wall of the hopper body is fixed with a plurality of mounting plates, the top surface of the mounting plate is provided with a positioning hole, and the inner wall of the positioning hole is slidably provided with a fixing bolt, and the mounting plate is connected by screw connection or lifting rope connection.

[0011] In use, the limiting block blocks the installation frame, preventing the installation frame from falling off due to excessive movement of the air cylinder, so that the installation frame is more stable during movement; through the cooperation of the mounting plate and the fixing bolt, the worker fixes the hopper body at the specified position; the worker can flexibly adjust the installation mode according to the installation environment of the hopper body.

[0012] Wherein, the outer wall of the tail end of the hopper body is fixed with a plurality of bearing blocks, the top surface of the bearing block is provided with a through hole, and the inner wall of the hopper body is provided with a plurality of inclined grooves.

[0013] During use, the tail end of the hopper body is limited and fixed by the load-bearing block to stabilize the hopper body and prevent swaying at the tail end, thereby increasing the feeding speed of iron ore powder. The inclined chute guides the iron ore powder when it comes into contact with the inner wall of the hopper body, allowing the iron ore powder to fall freely upon contact with the inner wall of the hopper body, preventing the iron ore powder from adhering and accumulating on the inner wall of the hopper body.

[0014] The system utilizes the combination of cylinder and push plate to move materials while reducing the space occupied inside the hopper. When the material flow rate is too low or too high, the flow detector will issue an early warning signal in time. The control system will adjust the working state of the cylinder and the pushing frequency and force of the push plate according to these signals to maintain a normal material flow rate.

[0015] Beneficial Effects: Compared with existing technologies, this invention has the following significant advantages: Through the cooperation of a cylinder and a pusher plate, this invention can periodically or as needed push the material during iron ore powder feeding, preventing the material from forming dead zones or accumulating in the hopper body, thereby avoiding blockages. Since powdery materials such as iron ore powder are prone to static electricity, humidity, and uneven particle size in the hopper, the movement of the pusher plate helps to evenly distribute the material in the hopper, ensuring that the material can be continuously and evenly supplied to the next processing stage, avoiding low production efficiency or equipment damage caused by uneven feeding. A flow detector can monitor the flow of material in the hopper body in real time and feed the data back to the control system. This invention solves the problem of blockages that easily occur in traditional hoppers when handling easily agglomerated and adherent materials such as iron ore powder, improving hopper flow, reducing downtime, increasing production efficiency, reducing maintenance costs, and reducing labor and time costs for workers.

Detailed Implementation

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1-6 As shown, the iron ore powder processing hopper with an anti-clogging structure of the present invention includes four limiting posts 1. Several of the limiting posts 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. An installation frame 3 is provided on the top surface of the hopper body 2. Sliding holes 4 are opened at the four corners of the top surface of the installation frame 3. The sliding holes 4 are slidably connected to the limiting posts 1. Several connecting plates 5 are fixed on the inner wall of the installation frame 3. A push plate 6 is rotatably connected to the bottom surface of the connecting plate 5 through a hinge. A pressing post 7 is fixed on one side of the push plate 6. Several installation grooves 8 are opened on the top surface of the hopper body 2. A cylinder 9 is fixed on the inner wall of the installation 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 installation frame 3. Installation holes 10 are opened on both the left and right sides of the tail end of the hopper body 2. A flow detector 11 is fixed on the inner wall of the right installation hole 10. Both the cylinder 9 and the flow detector 11 are electrically connected to the PLC controller.

[0025] During use, the cylinder 9 and the push plate 6 work together to periodically or as needed push the material when feeding iron ore powder, preventing the material from forming dead corners or accumulating in the hopper body 2, thus avoiding blockage. Since powdery materials such as iron ore powder are prone to static electricity, humidity, and uneven particle size in the hopper, the movement of the push plate 6 can help the material be evenly distributed in the hopper, ensuring that the material can be continuously and evenly supplied to the next processing stage, avoiding low production efficiency or equipment damage caused by uneven feeding. The flow detector 11 can monitor the flow of material 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 flow), the flow detector 11 can issue an early warning signal in time. The control system can adjust the working state of the cylinder 9 according to these signals, such as adjusting the pushing frequency and force of the push plate 6, to maintain normal material flow.

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

[0027] During use, the scraper 13, in conjunction with the spring 14, scrapes off the iron ore powder adhering to the inner wall of the hopper body 2 as the mounting frame 3 moves up and down. This prevents the iron ore powder from adhering to the inner wall of the hopper body 2 during the feeding process, allowing the iron ore powder to pass smoothly through the hopper body 2. This improves the feeding speed of the iron ore powder while ensuring the cleanliness of the inner wall of the hopper body 2. The air blowing pipe 15 can be connected to an air pump. When the flow detector 11 detects that the flow rate of the material in the hopper body 2 is too high, the flow detector 11 transmits a signal to the air pump through the PLC controller. The air pump then fills the material with air through the air blowing pipe 15, increasing the gap between the materials and effectively preventing material accumulation. Simultaneously, the vibration motor 16 increases the vibration frequency of the outer wall of the hopper body 2 when the material flow rate in the hopper body 2 is too high, thereby driving the material to move and preventing material agglomeration within 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 at the top of the limiting post 1, and several mounting plates 18 are fixed on the outer wall of the hopper body 2. The top surface of the mounting plate 18 is provided with a positioning hole 19, 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 rope connection.

[0029] During use, the limiting block 17 can block the mounting frame 3, effectively preventing excessive movement of the cylinder 9 and thus preventing the mounting frame 3 from falling off. This makes the mounting frame 3 more stable during movement, ensuring the smooth operation of the hopper body 2 and improving its safety. The mounting plate 18 and fixing bolts 20 allow workers to easily fix the hopper body 2 in the designated position. Furthermore, workers can flexibly adjust the installation method according to the installation environment, making the hopper body 2 adaptable to different installation environments and improving its adaptability.

[0030] like Figure 1 , Figure 2 ,Figure 3 , Figure 5 and Figure 6 As shown, several load-bearing blocks 21 are fixed on the outer wall of the tail end of the hopper body 2. The top surface of the load-bearing blocks 21 is provided with through holes 22, and several inclined grooves 23 are provided on the inner wall of the hopper body 2.

[0031] During use, the load-bearing block 21 can limit and fix the tail end of the hopper body 2, making the hopper body 2 more stable and preventing swaying at the tail end, thereby increasing the feeding speed of iron ore powder. It also facilitates the installation of the hopper body 2 by the workers. The inclined groove 23 can guide the iron ore powder when it comes into contact with the inner wall of the hopper body 2, allowing the iron ore powder to fall freely upon contact, preventing adhesion and accumulation on the inner wall of the hopper body 2, thus improving the practicality of the hopper body 2.

[0032] This invention, through the cooperation of a cylinder and a pusher plate, can reduce the space occupied inside the hopper while pushing the material. When the material flow is abnormal (such as too low or too high), the flow detector can issue an early warning signal in time. 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 pusher plate, in order to maintain a normal material flow.

[0033] This invention, through the cooperation of a cylinder and a pusher plate, periodically or as needed, propels iron ore powder during feeding, preventing dead zones or accumulation within the hopper and thus avoiding blockages. Since powdery materials like iron ore are prone to static electricity, humidity, and uneven particle size in the hopper, the pusher plate's movement helps distribute the material evenly, ensuring a continuous and uniform supply to the next processing stage. This avoids low production efficiency or equipment damage caused by uneven feeding. A flow detector monitors the material flow in the hopper in real time and feeds the data back to the control system. This invention solves the problem of blockages in traditional hoppers when handling easily agglomerated and adhesive materials like iron ore powder, improving hopper flow, reducing downtime, increasing production efficiency, lowering maintenance costs, and reducing labor and time costs for workers.
