Description

Technical Field

[0001] The invention relates to the technical field of anti-jamming of feeders, and in particular to a novel anti-jamming feeding device. Background Art

[0002] Limestone powder silo feeding device is used to quantitatively and continuously feed limestone powder stored in the silo to the next processing link according to process requirements. This device is widely used in cement manufacturing, flue gas desulfurization (FGD), steel manufacturing and other industries, because these industries often need to use limestone as a raw material or additive.

[0003] During the daily operation of the limestone powder silo feeding device, the feeder often gets stuck. The reason is that the stone powder at the bottom of the powder silo cone bucket becomes damp and hardens into lumps due to the influence of moisture inside the slurry box directly below. The lumps fall into the feeder and cause the lumps to get stuck in the feeder. On the other hand, the upward flow of moisture causes the powder to accumulate and harden at the end covers on both sides of the feeder, resulting in inflexible rotation and jamming. It is common for the upward flow of moisture to affect the fluidity of the powder. This situation leads to problems such as poor material flow and blockage, which in turn affects production efficiency. It is urgent to invent a structure that eliminates the upward flow of moisture and prevents the hardening of stone powder to improve the reliability of feeder operation. Summary of the invention

[0044] See also Figure 1-3 As shown, a novel anti-jamming feeding device is provided in the embodiment of the present application, comprising:

[0045] The limestone powder bin feeding mechanism 1 has a conical hopper at the bottom thereof for feeding the limestone powder;

[0046] The air supply unit 2 extracts external air and transmits it to the conical hopper of the limestone powder bin feeding mechanism, thereby providing a clean and stable air source to the conical hopper of the limestone powder bin feeding mechanism;

[0047] The heating unit 3 is connected to the air supply unit, receives the air provided by the air supply unit, heats the air provided by the air supply unit to a suitable temperature when passing through the heating unit to achieve the desired drying effect, and converts the air provided by the air supply unit into hot air;

[0048] Connecting pipes and valves connect the air supply unit and the heating unit, and connect the heating unit and the conical hopper. They are responsible for transmitting the air provided by the air supply unit to the heating unit via the connecting pipes, and transmitting the air heated by the heating unit from the heating unit to the position of the conical hopper via the connecting pipes. Valves can be set as needed, and the hot air supply can be adjusted or certain areas can be closed by adjusting the valves.

[0049] The fluidizing plate 4 is located on the side wall of the conical hopper, connected to the heating unit through the connecting pipe, receives the hot air formed after being heated by the heating unit, and is used to evenly distribute the hot air; the fluidizing plate allows gas to pass through but prevents solid particles from passing through, thereby forming a boiling-like state to allow the limestone powder to float in the conical hopper to increase fluidity;

[0050] A control system, electrically connected to the limestone powder bin feeding mechanism, the air supply unit, the heating unit and the valve, for controlling the operating parameters of the limestone powder bin feeding mechanism, the air supply unit, the heating unit and the valve, and controlling the air intake of the air supply unit, the heating temperature of the heating unit, the opening and closing of the valve and the opening size;

[0051] The safety protection unit is arranged in the connecting pipe and is electrically connected to the control system to ensure the safe operation of the device and to stop working in time to prevent accidents under abnormal circumstances.

[0052] Specifically, when the device is started, the air supply unit 2 starts working first, extracts external air, and delivers it to the heating unit 3 through the connecting pipe. The heating unit 3 receives the air from the air supply unit and uses an electric heating element or a steam heat exchanger to heat the air to a preset temperature. This temperature is set according to the material characteristics and the required drying effect. The control system monitors the working state of the heating unit 3 to ensure that the heating process is carried out within a safe range. The heated hot air is delivered to the position of the conical hopper 111 through the connecting pipe. In this process, the flow rate of the hot air can be adjusted by the valve to meet different operating requirements. The valve can be opened, closed or adjusted according to the instructions issued by the control system, thereby controlling the amount of hot air entering the conical hopper 111. After receiving the hot air, the fluidizing plate 4 located on the side wall of the conical hopper 111 evenly distributes the hot air. The design of the fluidizing plate 4 allows gas to pass but prevents solid particles from passing, so that the hot air can effectively penetrate the material layer. Under the action of hot air, the limestone powder forms a boiling-like state in the conical hopper 111, the material particles are suspended, the fluidity is significantly improved, the adhesion between the materials is reduced, and it is easy to transport smoothly. The limestone powder with improved fluidity is easier to discharge from the conical hopper and enter the subsequent production process. The feeding mechanism delivers the material at the set speed and method, and the entire feeding process is more stable and efficient. The control system continuously monitors the working parameters of each part, including the air intake of the air supply unit 2, the heating temperature of the heating unit 3, and the opening and closing and opening size of the valve. The control system can also automatically adjust these parameters according to real-time data to optimize the performance of the entire system. The safety protection unit is installed in a key position. Once an abnormal situation (such as overtemperature, overpressure) is detected, it will immediately send a signal to the control system to trigger corresponding emergency measures, such as stopping heating or cutting off the gas source to prevent accidents. In order to ensure the long-term and reliable operation of the system, the heating unit, fluidizing plate, and all connecting pipes and valves need to be regularly inspected and maintained. Replacing worn parts and calibrating sensors are common maintenance tasks. Through such a working process, the fluidized hot air device can significantly improve the fluidity of the material while keeping the material dry, ensuring that the feeding operation of the limestone powder is smoother and more efficient.

[0053] See also Figure 1 As shown, the limestone powder bin feeding mechanism 1 comprises:

[0054] A limestone powder bin 11, wherein the limestone powder bin 11 is used to load limestone powder, and the conical hopper 111 is provided at the bottom thereof;

[0055] A limestone slurry tank 12 is disposed below the limestone powder bin 11 and below the conical hopper 111, and is used to receive the limestone powder;

[0056] A rotary feed valve 13 is provided at the discharge end of the limestone powder bin 11 and is used for quantitatively conveying limestone powder;

[0057] A manual plug-in door 14 is provided on the limestone powder bin 11 and can be opened or closed by manual operation to cut off the material flow during maintenance to ensure a safe working environment;

[0058] The pneumatic gate 15 is provided on the limestone powder bin 11 and is an automatic control component that realizes opening and closing actions by driving an actuator such as a cylinder through compressed air. The pneumatic gate 15 is used to determine whether the limestone powder bin 11 is fed with material.

[0059] It should be noted that the rotary feed valve 13 is mainly used for quantitative delivery of powdered materials such as limestone powder. Its structural feature is that a rotor with blades is installed in a fixed shell. As the rotor rotates, each blade will carry a certain amount of material and discharge it through the discharge port. Therefore, the rotary feed valve can not only accurately control the material flow, but also has good sealing performance, which can effectively prevent dust from escaping. Allowing materials to flow smoothly without destroying the pressure balance in the pipeline is crucial to maintaining the stability of the entire system. The manual gate 14 is a device that can be opened or closed by manual operation. It is mainly used to cut off the material flow during maintenance to ensure a safe working environment. For example, when repairing equipment, the staff can close the manual gate to prevent the material from accidentally flowing out and causing danger or polluting the working area. In addition, the material supply can be quickly cut off during debugging or emergency situations. The pneumatic gate 15 is an automated control component that realizes the opening and closing action by driving an actuator such as a cylinder through compressed air. It is suitable for application scenarios that require frequent switching and require fast response speed. The advantage of using a pneumatic gate is that it can reduce labor costs and improve the automation and operation efficiency of the system. Likewise, they are used to isolate material flows, which is particularly useful in continuous production when process parameters need to be adjusted or when a malfunction requires immediate stopping of the feed.

[0060] See also Figure 3 As shown, the air supply unit 2 comprises:

[0061] A fluidizing fan 21, wherein the air inlet end of the fluidizing fan 21 is connected to an air inlet pipe 1, and the air outlet end of the fluidizing fan 21 is connected to an air transmission branch pipe 1;

[0062] Fluidizing fan 22, the air inlet end of the fluidizing fan 22 is connected to air inlet pipe 2, and the air outlet end is connected to air transmission branch pipe 2, the air transmission branch pipe 2 and the air transmission branch pipe 1 are commonly connected to a transmission main pipe 23, and the other end of the transmission main pipe 23 is connected to the heating unit 3.

[0063] See also Figure 2As shown, the heating unit 3 includes a fluidizing air heater, the air inlet end of the vulcanizing air heater is connected to the transmission main pipe 23, and the air outlet end thereof is connected to a hot air transmission pipe 33 connected to the fluidizing plate 4.

[0064] The valve comprises an air circulation valve 34, which is arranged on the transmission main pipe 23 and is used to determine whether to provide flowing air to the fluidizing air heater.

[0065] A plurality of fluidizing plates 4 are provided, which are respectively connected to the side walls of the conical hopper 111 through fixed structures. The position where the fluidizing plates 4 are connected to the conical hopper 111 is communicated with the interior of the conical hopper 111. A plurality of branch pipes are connected to the port of the hot air transmission pipe 33, which are respectively connected to the plurality of fluidizing plates 4. Switch control valves 35 are respectively provided on the plurality of branch pipes of the hot air transmission pipe 33, for determining whether to transmit hot air to the conical hopper 111.

[0066] To further optimize the above technical solution, the control system includes:

[0067] Programmable logic controller, as the core component, is responsible for executing preset control logic and algorithms;

[0068] Human-machine interface, used by operators to monitor system status, set parameters and issue instructions.

[0069] Preferably, according to a novel anti-jamming feeding device provided by the present invention, the safety protection unit comprises:

[0070] A plurality of temperature sensors are provided, which are respectively arranged in the heating unit and the conical hopper, and are used to monitor the temperature in the heating unit and the silo;

[0071] A pressure sensor is provided in the air supply unit and is used to detect the pressure of the air source to ensure that the air supply pressure is within a normal range;

[0072] A flow meter is arranged in the hot air transmission pipe to measure the gas flow through the pipe to adjust the air intake;

[0073] The humidity sensor is arranged in the conical hopper to monitor the humidity in the conical hopper and control the dryness of the material through monitoring.

[0074] The controller is equipped with an alarm system to promptly notify the operator in case of abnormal conditions such as overvoltage or undervoltage.

[0075] Working principle: The operator sets the initial parameters, including target temperature, pressure, flow rate, etc., through the HMI. The PLC receives these set values ​​and starts to initialize the system. Fluidizing fan 1 21 and fluidizing fan 2 22 are started, and air is drawn from the outside and sent to the heating unit 3 through the transmission main pipe 23. After receiving the clean air, the fluidizing air heater heats it to the set temperature. The temperature sensor monitors the temperature in the heating unit and feeds the data back to the PLC to ensure that the temperature meets the requirements. The heated hot air is transported to the multiple fluidizing plates 4 on the side wall of the conical hopper 111 through the hot air transmission pipe 33. The hot air supply of each fluidizing plate 4 can be individually controlled by the switch control valve 35 to achieve more precise local control. The hot air enters the conical hopper 111 through the fluidizing plate 4, suspending the limestone powder, forming a boiling state, and improving fluidity. The design of the fluidizing plate 4 prevents solid particles from passing through and only allows gas to pass through, ensuring that the material does not enter the air duct. The rotary feed valve 13 quantitatively transports the limestone powder to the limestone slurry tank 12 below according to the set speed. The manual gate 14 is closed during maintenance to cut off the material flow and ensure a safe working environment. The pneumatic gate 15 drives the cylinder with compressed air to automatically control the opening or closing of the feeding. The pressure sensor detects the pressure of the air supply unit to ensure that the air supply pressure is within the normal range. The flow meter measures the gas flow through the pipeline, and the PLC automatically adjusts the fan speed or other parameters according to the difference between the actual flow and the set value. The humidity sensor monitors the humidity in the conical hopper to help control the dryness of the material. The PLC continuously collects data from each sensor, analyzes and processes it, and adjusts relevant parameters such as intake volume, heating temperature, valve opening, etc. as needed. If the temperature sensor detects an overtemperature condition, or the pressure sensor detects an abnormal pressure, the PLC will trigger the alarm system to notify the operator in time. In extreme cases, the PLC can automatically shut down to prevent accidents.

[0076] The invention provides a novel anti-jamming feeding device, which introduces hot air to suspend material particles and keep them in a flowing state, thereby reducing the adhesion between materials and greatly improving the fluidity of the materials. The fluidized state can effectively avoid the agglomeration of materials due to high humidity, ensure that the materials are evenly dispersed, and are easy to transport and feed. The hot air can not only provide the necessary heat to evaporate the moisture in the material, but also allow the moisture to evaporate more evenly from the surface of the material through fluidization, thereby realizing an effective drying process. The material fluidity is improved and the risk of material blockage is reduced, which can speed up the feeding speed, reduce downtime, and thus improve the efficiency of the entire production line.
