Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to an automatic cleaning and anti-blocking device for a conical blanking bin, a hyperbolic blanking bin, and pipeline conveying. Background Art

[0002] Blocking often occurs during the conveying of viscous materials. Currently, the common methods to solve the blockage in general practice mainly include:

[0003] Manual blockage removal:

[0004] Manual blockage removal usually includes manually dredging the blocked hole, hitting the blocked part with a sledgehammer, etc. Disadvantages of manual blockage removal: It consumes a lot of manpower, cannot be dredged in a short time, and has limited effects; it causes great damage to the conveying pipeline or the bin wall;

[0005] Vibrator blockage removal:

[0006] The principle of the vibrator for blockage removal is the same as manual hitting. By vibrating, the viscous material adhered to the bin wall gradually detaches to achieve the purpose of blockage removal.

[0007] Disadvantages: The vibrator can only play its role at the position of arch formation. Since the position of arch formation and blockage of viscous materials is uncertain and changes continuously due to reasons such as the properties of the materials. If the vibrator is above the position of arch formation, the viscous material will become denser with vibration.

[0008] Air cannon blockage removal:

[0009] The working medium of the air cannon is compressed air. The main components include an air storage tank, an electromagnetic quick shut-off valve, and a control system, etc. When the quick shut-off valve is quickly opened, the compressed air in the air storage tank of the air cannon forms a strong air flow with high speed under the action of the pressure difference. The high-kinetic-energy air directly impacts the blocked part in the bin, making the material flow again under the action of gravity. Disadvantages: The air cannon can only play its role at the position of arch formation. Since the position of arch formation and blockage in the raw coal bin is uncertain and changes continuously due to reasons such as the coal quality. When the

[0010] air cannon is above the position of arch formation, the material will become denser with vibration. The baffle at the connection position between the air cannon and the inner wall of the bin increases the friction coefficient of the wall surface and increases the probability of material blockage. With air cannons all over the place, the bin wall is still knocked to be scarred. Content of the Utility Model

[0011] In order to overcome the above defects, the purpose of the utility model is to provide an anti-blocking device for viscous materials that can solve the blockage of materials in a conical bin or a hyperbolic

[0012] bin and pipeline discharging, and can realize automatic detection and blockage cleaning.

[0013] This utility model patent is designed to make up for the deficiencies of the prior art. It has a reasonable structure, is convenient to use, has the advantages of small investment, less occupied space, and can achieve maintenance-free operation throughout the year. It can effectively meet the anti-blocking requirements of viscous materials during transportation.

[0014] Technical solution of this utility model:

[0015] An anti-blocking device for viscous materials, characterized in that it consists of a housing, an upper connecting flange, an anti-blocking scraper, a housing bracket, a labyrinth seal, a material breakage detection device, a driving gear, a speed reducer, a driving motor, and a lower connecting flange. The upper part of the housing is connected to other equipment or components through the upper connecting flange; the anti-blocking scraper is installed inside the housing and fixed through connecting parts such as pins and screws; the housing is installed on the housing bracket, and the two are fixed through welding, bolt connection, etc.; the labyrinth seal is installed at an appropriate position of the housing for sealing; the material breakage detection device is installed inside or outside the housing through a mounting bracket or connecting parts; the driving gear is connected to the anti-blocking scraper to transmit power to make the anti-blocking scraper act; the output end of the speed reducer is connected to the driving gear, and the input end is connected to the driving motor; the lower part of the housing is connected to other equipment or components through the lower connecting flange.

[0016] This device of this utility model is installed on a platform and is connected to a silo or pipeline through the upper connecting flange and the lower connecting flange.

[0017] The anti-blocking scraper of this utility model is provided with at least four groups. The anti-blocking scraper is connected to the inner side of the large driving gear through bolts for easy replacement of the anti-blocking scraper. The anti-blocking scraper is divided into two sections, which respectively pass through the upper and lower sections of the anti-blocking device. The anti-blocking scraper makes a circular motion in the vertical plane along the inner side of the large driving gear.

[0018] The labyrinth seal of this utility model consists of a support bearing, a grease filling hole, and a clearance adjusting bolt. The labyrinth seal is filled with lithium-based grease through the grease filling hole, and the sealing clearance of the labyrinth seal is adjusted through the clearance adjusting bolt.

[0019] The material breakage detection device of this utility model can automatically detect whether there is a material breakage. After the material breakage, the material breakage detection device sends a signal to the PLC, and the PLC energizes the driving motor through the detected signal to realize the self-start of the anti-blocking device.

[0020] The material breakage detection device of this utility model is internally provided with a PLC control system and is also provided with a material breakage display, which can switch between manual / auto modes.

[0021] The working principle of this utility model is as follows: During operation, the viscous material enters the interior of the housing through the connected upper flange. The driving motor starts to operate, transmitting power to the speed reducer. After the speed reducer reduces the speed and increases the torque, the power is transmitted to the driving gear. The driving gear drives the anti-blocking scraper to rotate or reciprocate. During the material transportation process, the anti-blocking scraper continuously scrapes the inner wall of the housing to prevent the viscous material from adhering to the inner wall of the housing and causing blockage. The labyrinth seal is used to prevent the material from leaking through the connecting gaps of the device, ensuring the sealing performance of the device. The material breakage detection device monitors the flow condition of the material in real time. When the material flow stops or the flow rate is abnormal, it will send a signal back to the control system so that the operator can handle it in time. Finally, the material after anti-blocking treatment flows out of the device through the connected lower flange and enters the next process.

[0022] This anti-blocking device for viscous materials of the utility model has the following advantages:

[0023] High efficiency in anti-blocking: Through the setting of the anti-blocking scraper, it can timely and effectively scrape the viscous material adhering to the inner wall of the housing, prevent material blockage, and ensure the continuity and stability of material transportation.

[0025] Good sealing performance: The application of the labyrinth seal can effectively prevent material leakage, reduce material waste and environmental pollution, and at the same time ensure the stability of the working pressure and working environment inside the device.

[0026] Stable power transmission: The driving motor provides power for the anti-blocking scraper through the speed reducer and the driving gear, enabling stable power transmission and speed adjustment, and adapting to different working conditions and material characteristics.

[0027] Sturdy structure: The housing bracket provides stable support for the entire device, enabling the device to remain stable during operation and reducing failures and damages caused by vibration or external forces.

[0028] Convenient installation: Through the connected upper flange and the connected lower flange, this anti-blocking device can be conveniently connected to the upstream and downstream equipment, is easy to install and disassemble, and is convenient for equipment maintenance and repair.
