Description

Technical Field

[0001] This utility model relates to the technical field of preventing chute blockage, and in particular to a blockage-clearing device for preventing chute blockage. Background Technology

[0002] Sintered mixtures are raw materials prepared by mixing and granulation processes in metallurgical engineering. They consist of iron ore powder, flux, return ore and binder. They need to be moistened with water, mixed and granulated to form a mixture with a suitable particle size. The moisture stability of the mixture directly affects the quality of sintered ore.

[0003] The stockpiling of the mixture mainly uses conveyor belts for transport, with the discharge port and the conveyor belt connected by inclined chutes. However, when the moisture content of the mixture is too high, it often sticks to the bottom of the inclined chutes and gradually accumulates, causing blockage. Therefore, a blockage-clearing device is needed to prevent the inclined chutes from becoming blocked. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a device for preventing blockages in inclined chute. The device uses a mixture adhered to the bottom of a pipe to drive a conveyor belt to rotate until the mixture moves to the bottom of the conveyor belt. Under the action of gravity, the mixture detaches from the conveyor belt, thereby preventing the mixture from accumulating inside the pipe and thus preventing pipe blockage.

[0005] This utility model is achieved through the following technical solution: a device for preventing blockage of an inclined chute, comprising an inclined chute pipe; a plurality of rollers arranged sequentially along the axial direction of the pipe, the axes of the rollers being parallel to the bottom surface of the pipe and perpendicular to the axis of the pipe; the rollers being connected by a conveyor belt, which is fitted onto the bottom surface of the pipe; the conveyor belt is rotated by a mixture adhering to the bottom of the pipe until the mixture moves to the bottom of the conveyor belt, where it detaches from the conveyor belt under gravity, thereby preventing the mixture from accumulating inside the pipe and thus preventing blockage.

[0006] As an optimization, a drive mechanism for driving the rollers to rotate is fixed on the pipeline, and each roller is connected by a transmission belt; the drive mechanism drives the rollers to rotate, thereby driving the transmission belt to rotate, thus avoiding pipeline blockage caused by the transmission belt being unable to rotate.

[0007] As an optimization, a scraper is installed at the bottom of the pipe, with the cleaning end of the scraper extending towards the conveyor belt; the scraper cleans the mixture adhering to the conveyor belt, preventing the mixture from gradually sticking to the conveyor belt.

[0008] As an optimization, the scraper is hinged to the pipe, and the scraper is connected to the pipe via a return spring; the return spring ensures that the cleaning end of the scraper is always in contact with the conveyor belt, preventing the scraper from detaching from the conveyor belt due to wear.

[0009] As an optimization, the cleaning end of the scraper is tilted towards the conveyor belt, and the angle formed between the cleaning end of the scraper and the conveying direction of the conveyor belt is greater than 90°. By tilting the scraper, the contact area between the scraper and the mixture is reduced, thereby increasing the pressure between the scraper and the mixture, which makes it easier to clean the mixture on the conveyor belt.

[0010] As an optimization, the pipeline is equipped with nozzle A with its opening facing the conveyor belt. Nozzle A is connected to a water storage tank via a water pump. Nozzle A cleans the surface of the conveyor belt when the mixture is stopped, preventing the mixture from being difficult to clean due to prolonged adhesion to the conveyor belt.

[0011] As an optimization, the pipeline is equipped with nozzles B with openings facing the conveyor belt. Nozzles B are connected to a fan, and nozzles A and B are arranged sequentially along the conveying direction of the conveyor belt. Nozzles B dry the moisture on the conveyor belt, preventing the pipeline from corroding due to excessive contact with moisture.

[0012] As an optimization, the output end of the fan is connected to nozzle B through a heating mechanism; the heating mechanism heats the airflow ejected from nozzle B, increasing the efficiency of drying moisture on the conveyor belt.

[0013] The beneficial effects of this utility model are as follows: the mixture adhering to the bottom of the pipe drives the conveyor belt to rotate until the mixture moves to the bottom of the conveyor belt. Under the action of gravity, the mixture detaches from the conveyor belt, thereby preventing the mixture from accumulating in the pipe and thus preventing pipe blockage; the drive mechanism drives the roller to rotate, thereby driving the conveyor belt to rotate, preventing the pipe from being blocked due to the conveyor belt not being able to rotate; and the scraper cleans the mixture adhering to the conveyor belt, preventing the mixture from gradually adhering to the conveyor belt.

[0018] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0019] like Figure 1The present invention discloses a device for preventing blockage of an inclined chute, comprising an inclined chute pipe 1; a plurality of rollers 2 arranged sequentially along the axial direction of the pipe 1, wherein the axis of the rollers 2 is parallel to the bottom surface of the pipe 1 and perpendicular to the axis of the pipe 1; each roller 2 is connected by a conveyor belt 3, which is fitted onto the bottom surface of the pipe 1; the inlet at the upper end of the pipe 1 is connected to the outlet 13, which extends into the pipe 1; the outlet at the lower end of the pipe 1 is located directly above a conveying mechanism 14, and baffles 15 are provided on both sides of the conveying mechanism 14, with the outlet of the pipe 1 located below the top of the baffles 15.

[0020] The mixture is fed into pipe 1 and falls onto conveyor belt 3. The mixture is transported along pipe 1. The mixture adhering to conveyor belt 3 causes conveyor belt 3 to slide along the bottom of pipe 1. The moving roller 2 of conveyor belt 3 rotates until the mixture moves to the bottom of conveyor belt 3. Under the action of gravity, the mixture is separated from conveyor belt 3.

[0021] like Figure 1 A drive mechanism 4 for driving the rollers 2 to rotate is fixed on the pipe 1 shown. Each roller 2 is connected by a transmission belt 3. The drive mechanism 4 is existing technology and can be a motor. The output end of the rollers 2 and the motor are coaxially fixed.

[0022] The mixture is fed into pipe 1 and falls onto conveyor belt 3. The mixture is then transported along pipe 1. The drive mechanism 4 is activated, and the drive mechanism 4 drives the conveyor belt 3 to rotate through roller 2. The conveyor belt 3 carries the mixture along pipe 1 until the mixture moves to the bottom of the conveyor belt 3. Under the action of gravity, the mixture leaves the conveyor belt 3.

[0023] like Figure 1 and Figure 2 The bottom of the pipe 1 shown is equipped with a scraper 5, and the cleaning end of the scraper 5 extends toward the conveyor belt 3.

[0024] The mixture adhering to the conveyor belt 3 passes through the scraper 5, which automatically cleans the mixture adhering to the conveyor belt 3, and the mixture is removed from the conveyor belt 3.

[0025] like Figure 1 and Figure 2 The scraper 5 shown is hinged to the pipe 1, and the scraper 5 is connected to the pipe 1 through the return spring 6; the return spring 6 is existing technology and can be a torsion spring.

[0026] After the scraper 5 wears down from cleaning the mixture on the conveyor belt 3 for a long time, the return spring 6 relaxes, and the scraper 5 rotates toward the conveyor belt 3 under the action of the return spring 6. The cleaning end of the scraper 5 is always in contact with the conveyor belt 3.

[0027] like Figure 1 and Figure 2 The cleaning end of the scraper 5 shown is tilted towards the conveyor belt 3, and the angle formed between the cleaning end of the scraper 5 and the conveying direction of the conveyor belt 3 is greater than 90°.

[0028] The contact area between the scraper 5 and the mixture is reduced by the inclined scraper 5, thereby increasing the pressure between the scraper 5 and the mixture, which makes it easier to clean the mixture on the conveyor belt 3.

[0029] like Figure 1 and Figure 2 The pipe 1 shown is equipped with a nozzle A7 with its opening facing the conveyor belt 3. The nozzle A7 is connected to a water storage tank 9 through a water pump 8. The pipe 1 is equipped with a water collection tank 16, the nozzle A7 is located in the water collection tank 16, and the water collection tank 16 extends towards the conveyor belt 3.

[0030] After the mixture stops being transported, the conveyor belt 3 continues to rotate. The water pump 8 is turned on, and the water in the water tank 9 is sprayed out through the nozzle A7. The water sprayed out by the nozzle A7 cleans the surface of the conveyor belt 3.

[0031] like Figure 1 and Figure 2 The pipe 1 shown is equipped with a nozzle B10 with its opening facing the conveyor belt 3. The nozzle B10 is connected to a fan 11, and the nozzles A7 and B10 are arranged sequentially along the conveying direction of the conveyor belt 3.

[0032] Turn on the fan 11, and the nozzle B10 sprays airflow toward the conveyor belt 3, accelerating the evaporation of moisture on the surface of the conveyor belt 3.

[0033] like Figure 1 and Figure 2 The output end of the fan 11 shown is connected to the nozzle B10 through the heating mechanism 12; the heating mechanism 12 is existing technology.

[0034] Turn on the fan 11, and the nozzle B10 sprays airflow toward the conveyor belt 3; turn on the heating mechanism 12, and the heating mechanism 12 heats the airflow; the high-temperature airflow sprayed by the nozzle B10 accelerates the evaporation of moisture on the surface of the conveyor belt 3.

[0035] In actual use, the mixture is fed into pipe 1 and falls onto conveyor belt 3, which then transports the mixture along pipe 1. The drive mechanism 4 is activated, and the drive mechanism 4 drives the conveyor belt 3 to rotate via roller 2. The conveyor belt 3 carries the mixture along pipe 1 until the mixture moves to the bottom of the conveyor belt 3 and detaches from the conveyor belt 3 under the action of gravity. The mixture adhering to the conveyor belt 3 passes through scraper 5, which automatically cleans the mixture adhering to the conveyor belt 3, and the mixture detaches from the conveyor belt 3. After the scraper 5 wears down from cleaning the mixture on the conveyor belt 3 for a long time, the return spring 6 relaxes, and the scraper 5 rotates toward the conveyor belt 3 under the action of the return spring 6. The cleaning end of the scraper 5 is always in contact with the conveyor belt 3.

[0036] After the mixture stops being transported, the conveyor belt 3 continues to rotate. The water pump 8 is turned on, and the water in the water tank 9 is sprayed out through the nozzle A7. The water sprayed out by the nozzle A7 cleans the surface of the conveyor belt 3. The blower 11 is turned on, and the nozzle B10 sprays air towards the conveyor belt 3. The heating mechanism 12 is turned on, and the heating mechanism 12 heats the air. The high-temperature air sprayed out by the nozzle B10 accelerates the evaporation of moisture from the surface of the conveyor belt 3.
