Description

Technical Field

[0001] This invention belongs to the field of coal and relates to flotation feeding technology, specifically a flotation machine feeding system for automatic addition of flotation reagents. Background Technology

[0002] Flotation involves using surfactants—foaming agents—that generate a large number of bubbles. When air is introduced into water or when agitation causes air to enter the water, the hydrophobic end of the surfactant oriented towards the air bubble at the gas-liquid interface, while the hydrophilic end remains in the solution, forming a bubble. Another surfactant, acting as a collector, adsorbs onto the surface of the solid mineral powder. This adsorption is selective depending on the mineral's properties. The basic principle is to utilize lattice defects on the crystal surface, allowing the outward-facing hydrophobic end to partially insert into the bubble. Thus, during flotation, the bubble may carry away the desired mineral powder, achieving the purpose of mineral beneficiation.

[0003] Currently, when coal is flotated, a fixed amount of flotation reagent is usually added to the flotation equipment. However, since the flotation reagent is transported into the flotation equipment through the feed pipe, a certain amount of flotation reagent is easily adhered to the feed pipe during the transport process. As a result, the actual amount of flotation reagent mixed with the coal slurry water cannot meet the requirements. At the same time, after the coal slurry water flotation work is completed, the slurry of the coal slurry water is not analyzed, so it is impossible to determine whether the flotation work is qualified.

[0004] Therefore, we propose a flotation machine feeding system with automatic addition of flotation reagents. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a flotation machine feeding system for automatic addition of flotation reagents.

[0006] The technical problem to be solved by this invention is:

[0007] How to accurately monitor flotation reagents and how to determine the qualification of flotation work of coal slurry water.

[0008] The objective of this invention can be achieved through the following technical solutions:

[0009] A flotation machine feeding system with automatic addition of flotation reagents includes a flotation device and a processor installed inside the flotation device. The processor is connected to a data acquisition module, an alarm module, a display module, and a server. The server is connected to a feeding determination module, a transmission monitoring module, a user terminal, a feeding monitoring module, a big data module, and a flotation analysis module. The user terminal is used to add coal slurry, collector, and frother to the flotation device according to specified dosages.

[0010] The data acquisition module is used to collect the initial dose of the material before entering the flotation device and the current dose of the material after entering the flotation device and send them to the processor. The processor sends the initial dose and the current dose of the material to the server. The server sends the initial dose and the current dose of the material to the transmission monitoring module.

[0011] The transmission monitoring module is used to monitor the transmission status of materials entering the flotation equipment, and to feed back the transmission loss of coal slurry, collector and frother to the server. The server sends the transmission loss of coal slurry, collector and frother to the feeding determination module. The feeding determination module is used to determine the loss status of materials in the flotation equipment and generate a material feeding signal or a normal material signal.

[0012] The data acquisition module is used to collect real-time material data of the mixture in the flotation device and send it to the processor. The processor sends the real-time material data to the server, and the server sends the real-time material data to the flotation analysis module and the feeding monitoring module.

[0013] The feeding monitoring module is used to monitor the dosage of materials in the flotation equipment, obtain the proportion of coal slurry water, collector, and frother in the mixture, and feed it back to the server. The server then sends the proportion of coal slurry water, collector, and frother in the mixture to the big data module.

[0014] The big data module is used to acquire the flotation parameters of coal slurry water under different reagent ratios, and send the corresponding flotation parameters of coal slurry water to the flotation analysis module according to the coal slurry water ratio, collector ratio, and frother ratio; the flotation analysis module is used to analyze the flotation status of the flotation equipment and generate flotation abnormality signals or flotation normal signals.

[0015] Furthermore, the initial dosage of the material is the initial dosage of coal slurry, collector, and frother before entering the flotation equipment;

[0016] The current dosage of the material is the real-time dosage of the coal slurry, collector, and frother after entering the flotation equipment.

[0017] Furthermore, the transmission monitoring process of the transmission monitoring module is as follows:

[0018] Obtain the initial dosage of coal slurry, collector, and frother, and then obtain the current dosage of coal slurry, collector, and frother.

[0019] The initial dose of coal slurry is compared with the current dose, and the current dose is subtracted from the initial dose to obtain the coal slurry transportation loss.

[0020] Similarly, by comparing the initial dose of the collector with the current dose, and the initial dose of the foaming agent with the current dose, the delivery loss of the collector and foaming agent can be obtained.

[0021] Furthermore, the determination process of the feeding determination module is as follows:

[0022] Obtain the transport loss thresholds corresponding to coal slurry, collector, and foaming agent stored in the server;

[0023] The transport losses of coal slurry, collectors, and foaming agents are compared with the corresponding transport loss thresholds.

[0024] If the conveying losses of coal slurry, collector, and foaming agent do not exceed the corresponding conveying loss threshold, a normal material signal is generated.

[0025] If any of the conveying losses of coal slurry, collector, or foaming agent exceed the corresponding conveying loss threshold, a material feeding signal is generated.

[0026] Furthermore, the feeding determination module feeds back the material feeding signal or the material normal signal to the server;

[0027] If the server receives a normal material signal, it will not perform any operation.

[0028] If the server receives a material feeding signal, it sends the material feeding signal, as well as the amount of conveying loss of coal slurry, collector or frother, to the user terminal. After receiving the material feeding signal, the user terminal adds the corresponding amount of coal slurry, collector or frother to the flotation equipment according to the amount of conveying loss.

[0029] Furthermore, the mixture is composed of coal slurry, a collector, and a foaming agent;

[0030] Real-time material data includes the total real-time dosage of the mixture, as well as the combined dosage of coal slurry, collector, and frother in the mixture.

[0031] The flotation parameters are the upper limit of particle diameter in a specified dose of coal slurry and the upper limit of the number of particles exceeding the upper limit of particle diameter.

[0032] Furthermore, the monitoring process of the feeding monitoring module is as follows:

[0033] Obtain real-time material data of the mixture in the flotation equipment to obtain the real-time total dosage of the mixture, as well as the mixed dosage of coal slurry, collector and frother in the mixture;

[0034] The coal slurry water mixing dosage is compared with the real-time total dosage of the mixture to obtain the coal slurry water ratio of the mixture;

[0035] Similarly, the proportions of collector and foaming agent in the mixture can be calculated.

[0036] Furthermore, the analysis process of the flotation analysis module is as follows:

[0037] Obtain the flotation parameters of coal slurry water and extract a specified dose of coal slurry water from the flotation equipment;

[0038] Particles exceeding the upper limit of particle diameter in a specified dose of coal slurry are extracted, and those particles exceeding the upper limit of particle diameter are recorded as substandard particles.

[0039] Then, the number of particles exceeding the standard was counted and recorded as the excess particle quantity;

[0040] If the number of particles exceeding the standard exceeds the upper limit for particles exceeding the standard, a flotation anomaly signal will be generated;

[0041] If the number of particles exceeding the standard does not exceed the upper limit for particles exceeding the standard, a normal flotation signal is generated.

[0042] Furthermore, the flotation analysis module feeds back the flotation abnormal signal or the flotation normal signal to the server, and the server sends the flotation abnormal signal or the flotation normal signal to the user terminal. If the user terminal receives the flotation normal signal, it does not perform any operation. If the user terminal receives the flotation abnormal signal, it controls the flotation equipment to stop working.

[0043] Compared with the prior art, the beneficial effects of the present invention are:

[0044] 1. This invention monitors the material entering the flotation equipment through a transmission monitoring module, obtains the transmission loss of coal slurry, collector, and frother, and sends it to the feeding determination module. The feeding determination module then determines the material loss in the flotation equipment and generates a material feeding signal or a normal material signal. This invention achieves precise monitoring of the flotation reagent dosage during coal slurry flotation through the cooperation of the transmission monitoring module and the feeding determination module.

[0045] 2. This invention monitors the material dosage in the flotation equipment through a feeding monitoring module, obtaining the proportions of coal slurry water, collector, and frother in the mixture, and sends this information to a big data module. The big data module then sends the corresponding flotation parameters of the coal slurry water to the flotation analysis module based on these proportions. Finally, the flotation analysis module analyzes the flotation status of the flotation equipment and generates flotation anomaly or normal flotation signals. Through the cooperation of the feeding monitoring module and the flotation analysis module, this invention can intelligently determine the qualification of the coal slurry water flotation process. Attached Figure Description

[0046] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0047] Figure 1 This is an overall system block diagram of the present invention. Detailed Implementation

[0048] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Example 1

[0050] Please see Figure 1 As shown, the flotation machine feeding system with automatic addition of flotation reagents includes flotation equipment and a processor installed inside the flotation equipment. The processor is connected to a data acquisition module, an alarm module, a display module, and a server. The server is connected to a feeding determination module, a transmission monitoring module, a user terminal, a feeding monitoring module, a big data module, and a flotation analysis module.

[0051] The user terminal is used by staff to register and log in to the system after entering personal information, and to send the personal information to the server for storage. The personal information includes the staff's name, ID card number, mobile phone number, etc.

[0052] In practice, the user terminal is used to add coal slurry, collector and frother to the flotation equipment according to the specified dosage;

[0053] In this embodiment, the data acquisition module is used to acquire the initial dose of the material before entering the flotation device and the current dose of the material after entering the flotation device, and send the initial dose and the current dose to the processor. The processor sends the initial dose and the current dose to the server. The server sends the initial dose and the current dose to the transmission monitoring module.

[0054] It should be specifically noted that the initial dosage of the material is the initial dosage of the coal slurry, collector, and frother before entering the flotation equipment; the current dosage of the material is the real-time dosage of the coal slurry, collector, and frother after entering the flotation equipment. The data acquisition module can be a dosing instrument, electronic metering valve, etc. in actual settings.

[0055] Specifically, the initial dosage of materials is the initial amount of coal slurry, collector, and frother, and the current dosage of materials is the current amount of coal slurry, collector, and frother delivered to the mixer.

[0056] In practice, flotation equipment includes a dosing system, a conveying system, and a flotation system. The conveying system may be equipped with a mixer for receiving coal slurry and flotation reagents. The mixer sends the mixture of coal slurry and flotation reagents to the distribution box through the conveying pipeline. The distribution box is connected to the flotation system. The conveying pipeline is also equipped with an electromagnetic flow meter and an isotope density meter.

[0057] The transmission monitoring module is used to monitor the transmission of materials entering the flotation equipment. The transmission monitoring process is as follows:

[0058] Obtain the initial dosage of coal slurry, collector, and frother, and then obtain the current dosage of coal slurry, collector, and frother.

[0059] The initial dose of coal slurry is compared with the current dose, and the current dose is subtracted from the initial dose to obtain the coal slurry transportation loss.

[0060] Similarly, by comparing the initial dose of the collector with the current dose, and the initial dose of the frother with the current dose, the delivery loss of the collector and frother can be obtained.

[0061] The transmission monitoring module feeds back the transmission loss of coal slurry, collector and frother to the server, and the server sends the transmission loss of coal slurry, collector and frother to the feeding determination module.

[0062] The feeding determination module is used to determine the material loss in the flotation equipment. The determination process is as follows:

[0063] Obtain the transport loss thresholds corresponding to coal slurry, collector, and foaming agent stored in the server;

[0064] The transport losses of coal slurry, collectors, and foaming agents are compared with the corresponding transport loss thresholds.

[0065] If the conveying losses of coal slurry, collector, and foaming agent do not exceed the corresponding conveying loss threshold, a normal material signal is generated.

[0066] If any of the conveying losses of coal slurry, collector, or foaming agent exceed the corresponding conveying loss threshold, a material feeding signal is generated.

[0067] The feeding determination module feeds back the material feeding signal or the material normal signal to the server. If the server receives the material normal signal, it does not perform any operation. If the server receives the material feeding signal, it sends the material feeding signal, as well as the conveying loss of coal slurry, collector or foaming agent to the user terminal.

[0068] In practice, after receiving the material feeding signal, the user terminal adds the corresponding amount of coal slurry, collector or frother to the flotation equipment according to the amount of conveying loss.

[0069] In this embodiment, the data acquisition module is used to acquire real-time material data of the mixture in the flotation device and send the real-time material data to the processor. The processor sends the real-time material data to the server, and the server sends the real-time material data to the flotation analysis module and the feeding monitoring module. The mixture is composed of coal slurry, collector and frother.

[0070] It should be specifically noted that the real-time material data includes the total real-time dosage of the mixture and the mixed dosage of coal slurry, collector, and frother in the mixture. If a material feeding signal is generated, the mixed dosage is the real-time dosage of coal slurry, collector, or frother plus the corresponding conveying loss. If a normal material signal is generated, the mixed dosage is the real-time dosage of coal slurry, collector, or frother mentioned above.

[0071] The feeding monitoring module is used to monitor the dosage of materials in the flotation equipment. The monitoring process is as follows:

[0072] Obtain real-time material data of the mixture in the flotation equipment to obtain the real-time total dosage of the mixture, as well as the mixed dosage of coal slurry, collector and frother in the mixture;

[0073] The coal slurry water mixing dosage is compared with the real-time total dosage of the mixture to obtain the coal slurry water ratio of the mixture;

[0074] Similarly, the proportions of collector and foaming agent in the mixture were calculated.

[0075] The feeding monitoring module feeds back the proportions of coal slurry and water, collector, and frother in the mixture to the server, and the server sends the proportions of coal slurry and water, collector, and frother in the mixture to the big data module.

[0076] Specifically, the big data module is connected to the external Internet. The big data module is used to obtain the flotation parameters of coal slurry water under different reagent ratios. The big data module sends the flotation parameters corresponding to the coal slurry water to the flotation analysis module according to the coal slurry water ratio, collector ratio, and frother ratio.

[0077] Specifically, the flotation parameters are the upper limit of particle diameter in a specified dose of coal slurry and the upper limit of the number of particles exceeding the upper limit of particle diameter.

[0078] For example, if the collector accounts for 10% and the frother accounts for 8%, then the upper limit of particle diameter in the specified dosage of coal slurry is 10mm, and the upper limit of the number of particles exceeding the upper limit of particle diameter is n. The specific values ​​of the percentage, the upper limit of particle diameter, and the upper limit of the number of particles exceeding the limit are all examples here.

[0079] Generally, flotation design is typically a flotation concentrator. In flotation equipment, coal slurry is treated with reagents (collectors and frothers), and simultaneously agitated and aerated. This causes certain mineral particles in the coal slurry to selectively adhere to the air bubbles and float to the surface of the slurry, where they are scraped off to form a froth product. The remaining portion remains in the coal slurry, thus achieving the purpose of mineral separation.

[0080] The flotation analysis module is used to analyze the flotation performance of the flotation equipment. The analysis process is as follows:

[0081] Obtain the flotation parameters of the coal slurry water obtained above, and extract a specified amount of coal slurry water from the flotation equipment;

[0082] Particles exceeding the upper limit of particle diameter in a specified dose of coal slurry are extracted, and those particles exceeding the upper limit of particle diameter are recorded as substandard particles.

[0083] Then, the number of particles exceeding the standard was counted and recorded as the excess particle quantity;

[0084] If the number of particles exceeding the standard exceeds the upper limit for particles exceeding the standard, a flotation anomaly signal will be generated;

[0085] If the number of particles exceeding the standard does not exceed the upper limit for particles exceeding the standard, a normal flotation signal is generated;

[0086] It should be noted that excessive particles in coal slurry can be filtered out by a fine mesh screen. The mesh screen's aperture is equal to the upper limit of the particle diameter, so any particles larger than the upper limit of the particle diameter can be intercepted by the mesh screen.

[0087] The flotation analysis module feeds back flotation abnormality signals or flotation normal signals to the server. The server then sends the flotation abnormality signals or flotation normal signals to the user terminal. If the user terminal receives a flotation normal signal, it does not perform any operation. If the user terminal receives a flotation abnormal signal, it controls the flotation equipment to stop working.

[0088] Example 2

[0089] Based on another concept of the unified invention, a working method for an automatic flotation reagent addition system for a flotation machine is proposed. The specific working method is as follows:

[0090] In step S101, the user terminal adds coal slurry, collector and frother to the flotation equipment according to the specified dosage. Then the data acquisition module collects the initial dosage of the material before entering the flotation equipment and the current dosage of the material after entering the flotation equipment, and sends the initial dosage and the current dosage to the processor. The processor sends the initial dosage and the current dosage to the server. The server sends the initial dosage and the current dosage to the transmission monitoring module.

[0091] In step S102, the transmission monitoring module monitors the material entering the flotation equipment, obtaining the initial dosages of coal slurry, collector, and frother, and then the current dosages of these materials. The initial dosage of coal slurry is compared with the current dosage, and the current dosage is subtracted from the initial dosage to obtain the transmission loss of coal slurry. Similarly, the initial dosages of collector and frother are compared with the current dosages to obtain the transmission losses of collector and frother. The transmission monitoring module feeds back the transmission losses of coal slurry, collector, and frother to the server. The server sends the transmission losses of coal slurry, collector, and frother to the feeding determination module, which determines the material loss in the flotation equipment and obtains the coal slurry, collector, and frother values ​​stored on the server. The transport loss thresholds corresponding to the agents are compared with the transport loss amounts of coal slurry, collector, and frother. If the transport loss amounts of coal slurry, collector, and frother do not exceed the corresponding transport loss thresholds, a normal material signal is generated. If the transport loss amounts of any of the coal slurry, collector, or frother exceed the corresponding transport loss thresholds, a material feeding signal is generated. The feeding determination module feeds back the material feeding signal or the normal material signal to the server. If the server receives the normal material signal, it does not perform any operation. If the server receives the material feeding signal, it sends the material feeding signal and the transport loss amounts of coal slurry, collector, or frother to the user terminal. After receiving the material feeding signal, the user terminal adds the corresponding dosage of coal slurry, collector, or frother to the flotation equipment according to the transport loss amount.

[0092] Step S103: The data acquisition module acquires real-time material data of the mixture in the flotation device and sends the real-time material data to the processor. The processor sends the real-time material data to the server. The server sends the real-time material data to the flotation analysis module and the feeding monitoring module.

[0093] In step S104, the feeding monitoring module monitors the material dosage in the flotation equipment, obtains real-time material data of the mixture in the flotation equipment, and obtains the real-time total dosage of the mixture, as well as the mixed dosage of coal slurry water, collector, and frother in the mixture. The mixed dosage of coal slurry water is compared with the real-time total dosage of the mixture to obtain the proportion of coal slurry water in the mixture. Similarly, the proportion of collector and frother in the mixture is calculated. The feeding monitoring module feeds back the proportion of coal slurry water, collector, and frother dosage of the mixture to the server. The server sends the proportion of coal slurry water, collector, and frother in the mixture to the big data module. The big data module sends the flotation parameters corresponding to the coal slurry water to the flotation analysis module based on the proportion of coal slurry water, collector, and frother.

[0094] In step S105, the flotation analysis module analyzes the flotation status of the flotation equipment, obtains the flotation parameters of the coal slurry, and extracts a specified dose of coal slurry from the flotation equipment. Particles exceeding the upper limit of particle diameter in the specified dose of coal slurry are extracted and recorded as exceeding-standard particles. The number of exceeding-standard particles is then counted and recorded as the excess particle quantity. If the excess particle quantity exceeds the upper limit of the excess particle quantity, a flotation abnormality signal is generated. If the excess particle quantity does not exceed the upper limit of the excess particle quantity, a flotation normal signal is generated. The flotation analysis module feeds back the flotation abnormality signal or the flotation normal signal to the server. The server sends the flotation abnormality signal or the flotation normal signal to the user terminal. If the user terminal receives the flotation normal signal, no operation is performed. If the user terminal receives the flotation abnormal signal, the flotation equipment is controlled to stop working.

[0095] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
