Description

Technical Field

[0001] The present invention relates to the technical field of dust screen control, and in particular to an intermittent control system suitable for an environmentally friendly dust screen screening process. Background Art

[0002] The dust removal screen, also known as the vibrating screen dust collector, is a high-efficiency dust removal equipment. The vibrating screen body is driven by a motor to make the screen body vibrate at high frequency. The material jumps forward on the screen surface, thereby increasing the movement speed of the material on the screen surface, causing the coarse particles to fall through the screen holes, while the fine particles are retained on the screen surface.

[0003] However, in the prior art, when dust removal is controlled through a dust removal screen when grain is put into storage, it is impossible to detect the dust removal efficiency in real time, so that the dust removal level cannot be divided, it is impossible to ensure whether the current dust removal efficiency is met, and it is impossible to perform intelligent regulation according to the dust removal level and dust removal needs.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0008] The data monitoring module is used to monitor the feeding and dust removal environment of grains during the storage stage, collect grain feeding parameters and regional circulation data, and infer whether the corresponding data monitoring of the grain storage stage is qualified based on data comparison;

[0009] The dust removal real-time detection module performs real-time dust removal detection on the grain storage operation area, obtains the dust removal detection coefficient through data collection, and infers the dust removal level of the dust removal screen device based on the coefficient comparison;

[0012] As a preferred embodiment of the present invention, if the grain feeding parameter exceeds the time proportion numerical ratio threshold, and the regional circulation data exceeds the span numerical ratio threshold, a monitoring qualified signal is generated; if the grain feeding parameter does not exceed the time proportion numerical ratio threshold, or the regional circulation data does not exceed the span numerical ratio threshold, a monitoring unqualified signal is generated.

[0013] As a preferred embodiment of the present invention, the operation process of the dust removal real-time detection module is as follows:

[0014] Obtain the maximum deviation value of the dust content increase span before and after the grain dust removal screen device is operated during the grain storage stage, and mark the maximum deviation value of the dust content increase span before and after the grain dust removal screen device is operated during the grain storage stage as PC;

[0015] The maximum reciprocating control span of dust content after the grain dust removal screen device is operated during the grain entering the warehouse is collected, and the maximum reciprocating control span of dust content after the grain dust removal screen device is operated during the grain entering the warehouse is marked as KD; the dust removal detection coefficient is obtained by substituting it into the formula.

[0016] As a preferred embodiment of the present invention, the formula is Among them, CC is the dust removal detection coefficient, α is the dedimensionalization coefficient, which is used to dedimensionalize the collected data, and e is a natural constant.

[0017] As a preferred embodiment of the present invention, the dust removal detection coefficient is compared with the dust removal detection coefficient threshold:

[0018] If the dust removal detection coefficient exceeds the dust removal detection coefficient threshold, it is inferred that the dust removal screening device is at a high-efficiency operating level and is marked as a high-efficiency operating period; if the dust removal detection coefficient does not exceed the dust removal detection coefficient threshold, it is inferred that the dust removal screening device is at an inefficient operating level and is marked as a low-efficiency operating period.

[0019] As a preferred embodiment of the present invention, the operation process of the intelligent control module is as follows:

[0020] The speed of increase in the number of air outlets of the dust removal screen device that exceeds the set wind force value during the efficient operation period is obtained, and at the same time, the corresponding air volume ratio decrease span of the cumulative air volume of the air outlets that exceeds the set wind force value and the cumulative air volume of the air outlets that do not exceed the set wind force value during the inefficient operation period is obtained, and they are compared with the number increase speed threshold and the air volume ratio decrease span threshold, respectively.

[0021] As a preferred embodiment of the present invention, if the rate of increase in the number of air outlets of the dust removal screen device exceeding the set wind force value during the efficient operation period exceeds a threshold value for the rate of increase in the number, or if the air volume ratio decrease span corresponding to the cumulative air volume of the air outlets of the dust removal screen device exceeding the set wind force value and the cumulative air volume of the air outlets that do not exceed the set wind force value during the inefficient operation period exceeds a threshold value for the air volume ratio decrease span, an air volume control signal is generated;

[0025] 2. In the present invention, the dust removal is detected in real time in the grain storage operation area, and the dust removal efficiency is inferred to meet the actual demand through the dust removal detection, so as to grade the grain dust removal screening device and judge whether the screening level meets the preset screening requirements;

[0026] The dust removal screening device is intelligently controlled, and the air volume of each dust removal point is dynamically controlled according to the screening level to achieve dynamic distribution of the air volume of each dust removal point. When the feed volume in the feed circulation information is zero, the mechanical work is gradually stopped from front to back, which improves the operation control efficiency of the dust removal screening device and ensures the high efficiency of dust removal.

The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] See also Figure 1 As shown, an intermittent control system suitable for an environmental dust removal sieve screening process includes a control platform, the control platform is communicatively connected with a data monitoring module, a dust removal real-time monitoring module and an intelligent control module, and the data monitoring module is communicatively connected with the dust removal real-time monitoring module, and the dust removal real-time monitoring module is communicatively connected with the intelligent control module;

[0032] Grain storage requires the transportation of grain, and dust will be generated during the transportation stage. In order to ensure the operating environment and cleanliness of grain entering the warehouse, a dust removal screen is used to screen the grain when it enters the warehouse;

[0033] As a preferred feasibility example, the control platform generates a data monitoring signal and sends the data monitoring signal to the data monitoring module. The data monitoring module is used to monitor the feeding and dust removal environment of grain entering the warehouse. The current grain entering progress is inferred through data monitoring, and the dust during the grain entering the warehouse is also monitored and controlled, which improves the feasibility of grain entering the warehouse, and performs environmental control when entering the warehouse;

[0034] Obtain the corresponding numerical ratio of the continuous constant duration of the grain entry speed and the proportion of the total grain entry loss during the grain entry stage, and mark the corresponding numerical ratio of the continuous constant duration of the grain entry speed and the proportion of the total grain entry loss during the grain entry stage as the grain entry parameter;

[0035] Obtain the corresponding span value ratio of the increase span of the amount of grain entering the warehouse corresponding to the warehouse operation area during the grain entering the warehouse stage to the decrease span of the air circulation speed in the area, and mark the corresponding span value ratio of the increase span of the amount of grain entering the warehouse corresponding to the warehouse operation area during the grain entering the warehouse stage to the decrease span of the air circulation speed in the area as regional circulation data;

[0036] And the grain feeding parameters and regional circulation data are compared with the duration ratio threshold and span ratio threshold respectively:

[0037] If the grain feeding parameter exceeds the numerical ratio threshold of the duration ratio, and the regional circulation data exceeds the numerical ratio threshold of the span ratio, it is inferred that the corresponding data monitoring of the grain warehousing stage is qualified, and a qualified monitoring signal is generated and sent to the control platform. After receiving the qualified monitoring signal, the control platform continues to execute the grain warehousing operation;

[0038] If the grain feeding parameter does not exceed the duration ratio threshold, or the regional circulation data does not exceed the span ratio threshold, it is inferred that the corresponding data monitoring at the grain warehousing stage is unqualified, and a monitoring failure signal is generated and sent to the control platform. After receiving the monitoring failure signal, the control platform adjusts the grain warehousing operation and performs dust removal;

[0039] As a preferred feasibility example, a dust removal real-time detection signal is generated and sent to a dust removal real-time detection module. After receiving the dust removal real-time detection signal, the dust removal real-time detection module performs a dust removal real-time detection on the grain storage operation area, and infers whether the dust removal efficiency meets the actual demand through the dust removal detection, so as to grade the grain dust removal screening device and judge whether the screening level meets the preset screening requirements.

[0040] Obtain the maximum deviation value of the dust content increase span before and after the grain dust removal screen device is operated during the grain storage stage, and mark the maximum deviation value of the dust content increase span before and after the grain dust removal screen device is operated during the grain storage stage as PC;

[0041] The maximum reciprocating control span of dust content after the grain dust removal screen device is operated during the grain storage stage is collected, and the maximum reciprocating control span of dust content after the grain dust removal screen device is operated during the grain storage stage is marked as KD;

[0042] Substitute into the formula Among them, CC is the dust removal detection coefficient, α is the dedimensionalization coefficient, which is used to dedimensionalize the collected data, and e is a natural constant;

[0043] Compare the dust removal detection factor to the dust removal detection factor threshold:

[0044] If the dust removal detection coefficient exceeds the dust removal detection coefficient threshold, it is inferred that the dust removal screen device is at a high-efficiency operation level, and is marked as a high-efficiency operation period and sent to the management and control platform;

[0045] If the dust removal detection coefficient does not exceed the dust removal detection coefficient threshold, it is inferred that the dust removal screen device is at an inefficient operation level, and is marked as an inefficient operation period and sent to the management and control platform;

[0046] As a preferred feasibility example, an intelligent control signal is generated and sent to an intelligent control module. After receiving the intelligent control signal, the intelligent control module performs intelligent control on the dust removal screen device, dynamically controls the air volume of each dust removal point according to the screening level, and realizes dynamic distribution of the air volume of each dust removal point. When the feed volume in the feed circulation information is zero, the mechanical work is gradually stopped from the front to the back, thereby improving the operation control efficiency of the dust removal screen device and ensuring the high efficiency of dust removal execution.

[0047] The speed at which the number of air outlets of the dust removal screen device that exceeds the set wind force value is increased during the efficient operation period, and the corresponding air volume ratio decrease span of the cumulative air volume of the air outlets of the dust removal screen device that exceeds the set wind force value and the cumulative air volume of the air outlets that do not exceed the set wind force value during the inefficient operation period is obtained. The speed at which the number of air outlets of the dust removal screen device that exceeds the set wind force value during the efficient operation period and the corresponding air volume ratio decrease span of the cumulative air volume of the air outlets of the dust removal screen device that exceeds the set wind force value during the inefficient operation period are compared with the quantity increase speed threshold and the air volume ratio decrease span threshold, respectively:

[0048] If the rate of increase in the number of air outlets of the dust removal screen device that exceeds the set wind force value during the efficient operation period exceeds a threshold value for the rate of increase in number, or if the corresponding air volume ratio decrease span of the cumulative air volume of the air outlets of the dust removal screen device that exceeds the set wind force value and the cumulative air volume of the air outlets that do not exceed the set wind force value during the inefficient operation period exceeds a threshold value for the air volume ratio decrease span, it is inferred that the dust removal screen device in the current period needs to be operated and regulated, an air volume control signal is generated and sent to the control platform, and after receiving the air volume control signal, the control platform controls the air volume of the air outlet of the dust removal screen device, so as to reasonably distribute the current air volume and ensure the dust removal efficiency at each position;

[0049] If the rate of increase in the number of air outlets of the dust removal screen device that exceeds the set wind force value during the efficient operation period does not exceed the number increase rate threshold, and the corresponding air volume ratio decrease span of the cumulative air volume of the air outlets of the dust removal screen device that exceeds the set wind force value and the cumulative air volume of the air outlets that do not exceed the set wind force value during the inefficient operation period does not exceed the air volume ratio decrease span threshold, it is inferred that the dust removal screen device in the current period does not need to be operated and regulated, and an air volume stabilization signal is generated and sent to the control platform. After receiving the air volume stabilization signal, the control platform maintains a constant air volume at each air outlet;

[0050] The above formulas are obtained by collecting a large amount of data and performing software simulation, and a formula close to the actual value is selected. The coefficients in the formula are set by technicians in this field according to actual conditions;

[0051] When the present invention is used, the data monitoring module is used to monitor the feeding and dust removal environment of grains during the grain storage stage, collect grain feeding parameters and regional circulation data, and infer whether the corresponding data monitoring of the grain storage stage is qualified based on data comparison;

[0052] The real-time dust removal detection module performs real-time dust removal detection on the grain storage operation area, obtains the dust removal detection coefficient through data collection, and infers the dust removal level of the dust removal screen device based on the coefficient comparison; the intelligent management and control module performs intelligent management and control on the dust removal screen device.
