Description

Technical Field

[0001] This invention belongs to the field of metallurgical solid waste disposal technology, and relates to a disposal chamber system. Background Technology

[0002] Metallurgical solid waste contains a large amount of quicklime. When it is reused, the quicklime undergoes significant structural changes when it comes into contact with water. During the cold pressing process, the added water will react with the quicklime, causing the already formed pellets to expand and crack, resulting in a decrease in pellet strength and an increase in powder, which will have an adverse effect on subsequent utilization. Therefore, metallurgical solid waste needs to be fully digested before reuse.

[0003] Digestion is divided into yard digestion and warehouse digestion. Yard digestion has a poor investment environment, and warehouse digestion is currently more commonly used. However, in actual application, warehouse digestion has problems such as the emission of digestion exhaust gas causing a poor plant environment, the inability to intuitively view and control the digestion progress, and the untimely use of digested material leading to material blockage.

[0004] The present invention aims to solve the problems that occur in the digestion process by proposing a digestion chamber system that integrates dust removal and humidification, optimizes the batching equipment, and provides intelligent control. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a digestion chamber system to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A digestion chamber system includes a chamber body, a feeding device, a humidification device, and a dust removal device. A top cover plate is installed on the top of the chamber body, and a dust removal pipe interface for connecting the dust removal device and a humidification material inlet for connecting the humidification device are installed on the top cover plate.

[0008] The humidification device has a dry material inlet, a nozzle connected to a water supply pipe, and a humidification material outlet. The humidification material outlet is connected to the humidification material inlet, and the water supply pipe is connected to a water tank.

[0009] The dust removal device includes a dust removal pipe, a dust removal fan and a dust removal regulating valve installed on the dust removal pipe. The inlet of the dust removal pipe is connected to the dust removal pipe interface, and the outlet of the dust removal pipe is inserted into the water tank. The top of the water tank is provided with an exhaust port.

[0010] The feeding device includes a feeder, which includes a motor. A connector is fixed to the output end of the motor. The connector is rotatably installed at the bottom of the hopper and communicates with the hopper. A conical auger is provided at the center of the connector to discharge material through the rotation of the conical auger.

[0011] Furthermore, the silo body is a straight-section silo, and the interior of the silo body is equipped with an inner lining plate and a silo top material level detection device for detecting the material level.

[0012] Furthermore, a water pump is installed on the water supply pipe, and an electric regulating valve is installed on the side of the water supply pipe near the nozzle of the water pump. The inlet of the water supply pipe is connected to the bottom of the water tank.

[0013] Furthermore, a level gauge is installed on the upper part of the water tank to display the water level in real time.

[0014] Furthermore, the dust removal regulating valve is installed between the dust removal fan and the inlet of the dust removal pipe.

[0015] Furthermore, a dust detector for detecting dust concentration is also installed in the silo.

[0016] Furthermore, a compressed air nozzle is provided at the bottom of the water tank, the compressed air nozzle is connected to a compressed air pipeline, and a compressed air control valve is provided on the compressed air pipeline.

[0017] Furthermore, the feeding device also includes a small batching belt connected to the outlet of the feeder. The small batching belt is used to weigh the output of the feeder and switch the batching bin. The motor in the feeder is a variable frequency motor.

[0018] Furthermore, it also includes an intelligent digestion system for intelligent control of the digestion chamber system, wherein the intelligent digestion system is a visualization system that integrates a humidification system, a dust removal system, a digestion control system, and a batching system;

[0019] The humidification system obtains the amount and composition of the dry material through an external dry material conveying system connected to the dry material inlet of the humidification device, calculates the water consumption of the humidification device, and then controls the water pump and electric regulating valve to enter the water. The water level of the water tank is detected by the level gauge, and then the water tank is automatically replenished. The compressed air control valve is controlled to spray the bottom of the water tank at regular intervals.

[0020] The dust removal system uses a dust detector to detect the dust concentration in the silo and provides feedback adjustment to the dust removal fan and dust removal regulating valve to control the dust concentration in the silo.

[0021] The digestion control system calculates the digestion time by measuring the content of quicklime to be digested in the humidified material discharged into the silo by the humidification device. Then, it combines the feeding time, feeding amount and discharge amount of the humidified material to simulate the digestion process and the amount of digested material in the silo, and displays it visually.

[0022] The batching system calculates the amount of material to be discharged by using the amount of material already digested by the digestion control system, the real-time discharge amount of the feeding device, and the frequency conversion parameters of the motor. It also issues an early warning when the amount of material to be discharged is insufficient, and uses a small batching belt to measure the amount of material and automatically switch batching bins.

[0039] Please see Figures 1-5 The digestion chamber system includes a chamber body 1, a feeding device, a humidification device, a dust removal device, and an intelligent system.

[0040] Key references Figures 1-3 The top of the silo body 1 is snapped with a silo top cover plate, on which a dust removal pipe interface for connecting the dust removal device and a humidification material inlet (humidification device outlet inlet) for connecting the humidification device are installed. The silo body 1 consists of a straight silo, a silo inner lining plate, and a silo top material level detection device arranged inside the silo.

[0041] The humidification device has a dry material inlet and a nozzle connected to a water supply pipe. A water pump is installed on the water supply pipe, and an electric regulating valve is installed on the side of the water supply pipe near the nozzle. The inlet of the water supply pipe is connected to the bottom of the water tank to draw water from the tank. A level gauge is installed on the upper part of the water tank to display the water level in real time. When the water level reaches the bottom or low level, the water tank is automatically replenished with water, and the replenishment stops when the water level reaches the high level.

[0042] The dust removal device includes a dust removal pipe, a dust removal fan and a dust removal regulating valve installed on the dust removal pipe. The inlet of the dust removal pipe is connected to the top cover plate of the silo, and the dust removal regulating valve is installed between the dust removal fan and the inlet of the dust removal pipe. The outlet of the dust removal pipe extends through the top of the water tank into the interior of the water tank, and an exhaust port is provided at the top of the water tank so that the air purified by water in the dust removal device can be discharged from the exhaust port.

[0043] Specifically, a dust detector for detecting dust concentration is also provided in the silo 1.

[0044] Preferably, a compressed air nozzle is provided at the bottom of the water tank, the compressed air nozzle is connected to a compressed air pipeline, and a compressed air control valve is provided on the compressed air pipeline. The compressed air is stirred inside the tank through the compressed air nozzle.

[0045] The feeding device includes a feeder 2 and a quantitative feeding device. The feeder includes a motor, and a connector is fixed to the output end of the motor. The connector is rotatably installed at the bottom of the bin and communicates with the bin. A conical spiral component is provided at the center of the connector. The motor drives the connector to rotate when it is powered on, and the rotation drives the conical spiral component to rotate. The rotating conical spiral component can loosen the digested material in the bin, which plays a role in clearing the discharge and stabilizing the material flow, avoiding the problem of large fluctuations in the material flow.

[0046] The quantitative feeding device is a small batching belt 3 connected to the outlet of the feeder 2. The small batching belt 3 is used to detect whether the output of the feeder matches the system setting value, and then to adjust the motor of the feeder accordingly; and to switch the batching bins through the small batching belt.

[0047] The straight silo of the silo body 1 is a cylindrical silo with an anti-sticking liner. Compared with the traditional conical silo body, it consumes less steel for the same volume and avoids the problem of material blockage in the conical section. Correspondingly, the connecting part of the feeder 2 connected to the silo body 1 is a disc. When the conical spiral component rotates, it can discharge the digested material in the silo body, so that the material is discharged through the valve plate inside the shell. The motor is a variable frequency motor, which can be matched and adjusted according to the material requirements and system settings.

[0048] Preferably, the humidification device includes a feeding section and a humidification section. The feeding section is provided with a material equalization spiral blade, and the humidification section is provided with a spiral stirring blade to fully mix the water sprayed from the nozzle with the dry material, and to evenly discharge the humidified material as it rotates. The humidification device has multiple nozzles, which are evenly arranged on the top of the humidification section.

[0049] Preferably, the top of the water tank is also fixedly equipped with a water replenishment pipe, a water level gauge, an exhaust port, and a dust removal pipe inlet, and the bottom is equipped with a compressed air nozzle and a water supply pipe. The water tank is used to purify dust removal exhaust gas, stir sediment in the water tank, replenish water at low water levels, and stop replenishing water at high water levels.

[0050] Preferably, the dust removal device and the humidification device work together with a water tank to treat the exhaust gas, and the wastewater is reused as humidification water.

[0051] Preferably, the feeding device incorporates a conical spiral in the middle, which solves the problems of slow material discharge in the middle and caking due to excessively long intermediate digestion time when the feeding device disc is too large. A variable frequency motor is used to adjust the material discharge rate by adjusting the rotation speed. The silo body adopts a fully straight section design, which reduces the steel consumption per unit volume, better simulates the digestion and discharge process, and reduces the possibility of material blockage and caking.

[0052] Key references Figures 4-5 The intelligent digestion system is used to realize three major functions: data detection, data transmission, and data processing. The system includes a humidification system, a dust removal system, a digestion control system, and a batching system. Each system includes a human-machine interface (HMI) component (host computer), a slave computer containing a PLC module, a production and equipment data acquisition module, control outputs, and recording reports. The HMI component is connected to the PLC module, and the central controller component is connected to the metering elements, control outputs, and recording report signals. The beneficial effect of this invention is that, based on the differences in the composition of the digested material, a data-driven visualization model simulates intelligent information processing. Intelligent information feedback processing and detection element information provide data flow for intelligent control decisions, thus enabling automated control. The humidification system calculates the required water volume based on the raw material composition input from the host computer, and, combined with the on-site water tank volume, is digitally controlled and interlocked with the humidifier and water valves to achieve intelligent humidification, avoiding excessive water addition leading to spillage in the silo and insufficient water addition resulting in incomplete digestion. The dust removal system automatically controls the dust removal system valves and equipment based on the theoretical digestion time in the digestion model, and is interlocked with the water tank level. The batching system batches materials according to the sufficient amount of digestible material available in the digestion model, and measures the amount using data from the feeding belt scale. It adjusts the amount of material available for digestion in real time and is interlocked with the feeding system and batching equipment. The digestion control system, based on the batching data, feed rate, raw material data set in the host computer, and the theoretical digestion time in the digestion model, displays a visual progress bar of the digested material in the silo, showing in real time the amount of digestible material available for different time periods.

[0053] The external dry material conveying system connected to the dry material inlet of the humidification system and the humidification device obtains the incoming dry material quantity and raw material composition, automatically calculates the humidification device, adjusts the water inlet valve (electric regulating valve) to control the water flow, and realizes automatic start and stop of the water pump. The water tank detects the water level and automatically replenishes water. According to the set stirring time, it automatically performs compressed air stirring.

[0054] The dust removal system adjusts the dust removal fan and the dust removal regulating valve according to the dust concentration in the silo, thereby achieving real-time adjustment of the dust removal effect and ensuring that the dust concentration in the silo is always within the qualified range.

[0055] The digestion control system calculates the digestion time based on the content of quicklime to be digested in the mixed materials in the humidification device, and then combines parameters such as the feeding time, feeding amount and discharge amount of the humidified material in the bin to achieve a visual display of the digestion process in the bin and the amount of digested material;

[0056] The batching system uses the available discharge amount (already digested material amount) in the bin, the real-time discharge amount, and the parameters of the variable frequency motor in the feeder to realize the early warning display of insufficient discharge amount, and uses the batching belt 3 to realize the functions of batching amount measurement and automatic switching of batching bins.

[0057] Specifically, in this embodiment, the silo top level detection device, level gauge, electric regulating valve, batching conveyor belt, frequency converter motor, and dust detector are all data acquisition devices, and the electric regulating valve, batching conveyor belt, frequency converter motor, water pump, dust removal fan, dust removal regulating valve, and compressed air valve are all execution devices that receive and execute commands. The humidification system, dust removal system, digestion control system, and batching system are integrated into a visual control system, which acts as the host computer of the intelligent digestion system to receive data and issue commands. The various components equipped with data acquisition devices and / or execution devices act as slave computers to feed back data to the host computer and issue commands to the specific execution devices. It should be noted that since the technology for intelligent control of mechanized equipment is relatively mature in the prior art, and the key point of this application is to provide an intelligent digestion system, rather than intelligent control technology, the details of intelligent control will not be elaborated further.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
