Description

Technical Field

[0001] This invention relates to the field of environmental protection product molding technology, and more specifically, to a high-efficiency hydraulic press for molding columnar activated carbon into environmental protection products. Background Technology

[0002] In the field of environmentally friendly product molding, traditional hydraulic press molding control systems have many shortcomings. On the one hand, they lack effective monitoring and adaptive adjustment mechanisms for the complex environmental factors encountered during the molding process of different types of environmentally friendly products. For example, during production, environmental factors such as dust concentration and humidity constantly change, and existing control systems struggle to accurately adjust the hydraulic press's operating parameters based on these real-time changes, leading to unstable product quality. On the other hand, traditional control systems lack precision in controlling key parameters such as pressure and speed during the molding process. In environmentally friendly product molding, different materials and processes require extremely high precision in pressure and speed control. Insufficient control precision can result in uneven density, surface defects, and other problems, reducing the product's pass rate.

[0003] Therefore, it is necessary to design a high-efficiency and environmentally friendly hydraulic press for forming columnar activated carbon products to solve the problems existing in the current technology. Summary of the Invention

[0068] Referring to Figures 1-2 As shown in some embodiments of the present application, the present embodiment provides a cylindrical activated carbon high-efficiency environmentally friendly product forming hydraulic machine, comprising:

[0069] The forming device 100 and the control module 200, the forming device 100 comprises a feeding assembly and a pressing assembly, the feeding assembly is used for inputting the biomass material to be formed into the inside of the pressing assembly; the control module 200 is connected with the forming device 100, and the control module 200 comprises an acquisition part 210, a judgment part 220 and a processing part 230;

[0070] The acquisition part 210 is configured to acquire the material type and the forming specification of the biomass material to be formed, and determine the initial pressing parameters of the pressing assembly according to the material type and the forming specification; wherein the initial pressing parameters include the initial pressing pressure and the initial pressing speed;

[0071] The judgment part 220 is configured to acquire the kneading density change parameter and the material utilization parameter of the material to be formed, and judge whether to adjust the initial pressing parameters according to the kneading density change parameter and the material utilization parameter;

[0072] The processing part 230 is configured to, when it is determined to adjust the initial pressing parameters, acquire the first dust concentration inside the feeding assembly, the second dust concentration inside the pressing assembly and the environmental parameters inside the pressing assembly, and adjust the initial pressing parameters based on the first dust concentration, the second dust concentration and the environmental parameters to obtain the final pressing parameters.

[0073] In the present embodiment, the biomass material to be formed includes coal, bamboo, fruit shell and other biological waste materials.

[0074] It can be understood that the forming control system of the environment-friendly product forming hydraulic machine provided by the embodiment determines the initial pressing parameters by collecting the material type and forming specification of the biomass material to be formed, so that the pressing process is more targeted and accurate, and the pressure and speed can be reasonably set according to the characteristics of different materials, thereby improving the forming quality. The judgment part judges whether to adjust the initial pressing parameters according to the kneading density change parameter and the material utilization parameter, which can optimize the pressing parameters in time according to the actual situation of the material, avoid forming defects caused by inappropriate parameters, and improve the product qualification rate and material utilization rate. The processing part adjusts the initial pressing parameters based on the first dust concentration inside the feeding assembly, the second dust concentration inside the pressing assembly and the environmental parameters inside the pressing assembly, fully considers the influence of the working environment factors on the pressing process, and further ensures the stability and reliability of the pressing. This forming control system can adapt to different types and specifications of biomass materials, improve the versatility and flexibility of the environment-friendly product forming hydraulic machine, and help reduce production cost and improve production efficiency. At the same time, the system helps to improve the quality and performance of environment-friendly products, reduce the rate of defective products, reduce resource waste, and meet the requirements of environmental protection and sustainable development.

[0075] Specifically, the feeding assembly comprises:

[0076] a feeding frame 121;

[0077] a feeding hydraulic cylinder 122 and a feeding cavity 123, which are arranged on both sides of the feeding frame 121 respectively, and the feeding cavity 123 can extend into the pressing assembly;

[0078] a feeding hopper 124 arranged above the feeding cavity 123.

[0079] It can be understood that the structure design of the feeding assembly can effectively deliver the biomass material to be formed into the pressing assembly. The feeding hydraulic cylinder 122 provides power for the movement of the feeding cavity 123, so that it can smoothly deliver the material in the feeding hopper 124 into the pressing assembly. The feeding hopper 124 is arranged above the feeding cavity 123, which utilizes the action of gravity to facilitate the natural falling of the material into the feeding cavity 123, ensuring the smoothness of feeding. In the actual working process, after the initial pressing parameters are determined by the collecting part 210, the feeding assembly starts to work. The biomass material to be formed in the feeding hopper 124 falls into the feeding cavity 123 under the action of gravity, and the feeding hydraulic cylinder 122 pushes the feeding cavity 123 to extend into the pressing assembly, so as to accurately deliver the material to the designated position.

[0080] Specifically, the pressing assembly comprises:

[0081] a main frame 111;

[0082] The main hydraulic cylinder 112, the guide column 113, the sliding block 114 and the pressure cylinder assembly 115 are sequentially arranged from bottom to top in the vertical direction; the bottom of the main hydraulic cylinder 112 is fixedly connected with the top of the main frame 111, the bottom of the guide column 113 is fixedly connected with the top of the main hydraulic cylinder 112, the sliding block 114 is slidably sleeved on the guide column 113, and the piston rod of the pressure cylinder assembly 115 is fixedly connected with the sliding block 114;

[0083] The main hydraulic cylinder 112 forms a forming cavity for accommodating the biomass material to be formed, and the feeding cavity 123 can deliver the biomass material to be formed into the forming cavity; the bottom of the sliding block 114 is provided with a pressure head matched with the forming cavity, and when the pressure cylinder assembly 115 acts, the sliding block 114 is driven to slide downward along the guide column 113, so that the pressure head enters the forming cavity to press the biomass material to be formed.

[0084] It can be understood that the structure of the pressure assembly can effectively press the biomass material to be formed in the forming cavity. The main hydraulic cylinder 112 provides a stable forming space for the material, the guide column 113 provides accurate guidance for the sliding of the sliding block 114, and ensures that the pressure head can accurately enter the forming cavity for pressing operation. The pressure cylinder assembly 115 as a power source can provide sufficient pressure to make the pressure head apply appropriate pressure to the material to achieve the expected forming effect. After the feeding assembly delivers the biomass material to be formed into the forming cavity, the control module 200 controls the action of the pressure cylinder assembly 115 according to the initial pressure parameters or the final pressure parameters adjusted in advance. When the piston rod of the pressure cylinder assembly 115 extends, the sliding block 114 is driven to slide downward along the guide column 113, and the pressure head enters the forming cavity to gradually press the biomass material to be formed.

[0085] Specifically, when determining the initial pressure parameters of the pressure assembly according to the material type and the forming specification, the initial pressure parameters include:

[0086] Collecting forming stage information of the biomass material to be formed, and analyzing the forming stage information to obtain the forming stage of the biomass material to be formed;

[0087] According to the forming stage, the material type and the forming specification, a pressure vector group is constructed;

[0088] The pressure vector group is compared with the historical pressure group, and the initial pressure parameters of the biomass material to be formed are determined according to the comparison result;

[0089] When there is a historical pressure vector group same as the pressure vector group in the historical pressure group, the historical pressure parameters corresponding to the historical pressure vector group are taken as the initial pressure parameters;

[0090] When there is no historical compression vector group identical to the compression vector group in the historical compression group, a historical pressure-velocity change curve of the to-be-molded biomass material is extracted based on the molding stage, the material type and the molding specification, and the historical pressure-velocity change curve is analyzed, and initial compression parameters are determined based on the analysis result.

[0091] In the embodiment, the molding stage is preferably a pre-pressing stage. In the pre-pressing stage, the to-be-molded biomass material delivered into the molding cavity is mainly preliminarily compacted, and part of the air in the material is discharged, so as to prepare for subsequent compression work.

[0092] In the embodiment, when the historical pressure-velocity change curve is extracted based on the molding stage, the material type and the molding specification: first, historical molding records with the same material type (such as coal, bamboo, fruit shell, etc.) and similar molding specifications (such as target diameter, length, density, etc.) as the current to-be-molded biomass material are screened from the database. Then, for these screened historical records, the pressure data and the velocity data in the time period corresponding to the currently set molding stage (for example, the pre-pressing stage in the embodiment) are extracted. Then, these historical pressure data and velocity data are arranged in chronological order to form a plurality of historical pressure-velocity data pairs. Finally, the data pairs are processed by a data fitting algorithm (such as linear fitting, polynomial fitting or spline curve fitting, etc.) to generate a continuous curve that can reflect the pressure change rule with velocity or the velocity change rule with pressure of the material type under similar molding specifications in a specific molding stage, that is, the historical pressure-velocity change curve. Through analysis of the curve, for example, analyzing the slope change, the inflection point position and the parameters corresponding to specific pressure / velocity values, etc., and combining the subtle differences of the current molding requirements for fine tuning, the initial compression parameters suitable for the current to-be-molded biomass material can be determined.

[0093] It should be noted that in the embodiment, the extraction of the "historical pressure-velocity change curve" is not the same as the comparison of the "compression vector group and the historical compression group". The former is to derive the initial parameters through the pressure and velocity change rule of the same material, similar specifications and the same molding stage when there is a lack of completely matched historical data, and it is more focused on parameter estimation by using the dynamic change trend in the historical process. The latter is to directly match the historical parameter results under the same conditions, which is a parameter reuse method based on accurate matching. The combination of the two methods can quickly determine the parameters when there is completely matched data, and can realize reasonable setting of the parameters through trend analysis when there is insufficient data, thereby improving the comprehensiveness and accuracy of the determination of the initial compression parameters.

[0094] In the embodiment, the similar specifications specifically refer to a deviation range of the target diameter within ±0.5 mm, a deviation range of the length within ±2 mm, and a deviation range of the target density within ±0.05 g / cm3. For example, if the target molding specification of the current biomass material to be molded is a diameter of 50 mm, a length of 100 mm, and a density of 1.2 g / cm3, the records in the historical molding records with a molding specification of a diameter of 49.6 mm-50.5 mm, a length of 98 mm-102 mm, and a density of 1.15 g / cm3-1.25 g / cm3 are all considered to be similar to the current molding specification, and can be used as the basis data source for extracting the historical pressure-velocity change curve. Such a deviation range setting can ensure that the extracted historical data has high similarity with the current molding requirement, guarantee the reference value of the historical pressure-velocity change rule for determining the initial pressing parameters, and avoid the situation that not enough historical records are screened due to too strict specification requirements, thereby affecting the accuracy and reliability of the parameter derivation.

[0095] It can be understood that the method for determining the initial pressing parameters comprehensively considers the molding stage, type, and specification of the material and other factors. By constructing the pressing vector group and comparing with the historical pressing group, the past production experience can be fully utilized. When there is a same historical pressing vector group, the corresponding historical pressing parameters are directly used, which can quickly and accurately provide suitable initial parameters for the current molding work, avoid unnecessary groping and testing, and improve the production efficiency. When there is no same historical pressing vector group, the historical pressure-velocity change curve is analyzed, and the rule can be mined from the historical molding data of the material.

[0096] Specifically, when the initial pressing parameters are determined based on the analysis result, the following steps are included.

[0097] Each historical pressure-velocity change curve is analyzed to obtain the historical pressure characteristic value and the historical velocity characteristic value corresponding to each historical pressure-velocity change curve.

[0098] The pressure standard value and the velocity standard value corresponding to the historical pressure characteristic value and the historical velocity characteristic value are obtained, respectively.

[0099] The difference between each historical pressure characteristic value and the pressure standard value is calculated, and is recorded as a pressure difference value.

[0100] The difference between each historical velocity characteristic value and the velocity standard value is calculated, and is recorded as a velocity difference value.

[0101] The pressure difference value threshold and the velocity difference value threshold are set, all the historical pressure-velocity change curves with a pressure difference value less than or equal to the pressure difference value threshold and a velocity difference value less than or equal to the velocity difference value threshold are screened out, and the number thereof is counted and recorded as a curve number.

[0102] determining the initial pressing parameters according to the number of curves.

[0103] In the embodiment, the historical pressure characteristic value and the historical speed characteristic value are preferably a pressure peak value and a speed peak value, respectively. The pressure peak value can reflect the maximum pressure reached in the material forming process, which is of great significance for evaluating the ultimate bearing capacity of the material under pressure and determining the appropriate pressing pressure range. The speed peak value represents the maximum speed in the pressing process, and an appropriate speed peak value is crucial for ensuring the quality of the forming and production efficiency. If the speed peak value is too large, it may cause the material to be unevenly distributed in the forming cavity, affecting the forming effect; and if the speed peak value is too small, it will reduce the production efficiency.

[0104] In the embodiment, the pressure standard value refers to a theoretically optimal pressure value preset according to the material type and forming specification of the biomass material to be formed at the current forming stage (such as the pre-pressing stage). The speed standard value refers to a theoretically optimal speed value preset according to the material type and forming specification of the biomass material to be formed at the current forming stage.

[0105] It can be understood that this way of determining the initial pressing parameters based on the analysis results can further refine the analysis and utilization of historical data. By analyzing the historical pressure-speed change curve, the historical pressure characteristic value and the historical speed characteristic value are obtained, and then compared with the corresponding standard value to calculate the difference. Setting the difference threshold and selecting the curves that meet the conditions, and counting the number of curves, all these operations are to find the most matched pressure and speed parameters for the current biomass material to be formed from a large amount of historical data.

[0106] Specifically, when determining the initial pressing parameters according to the number of curves, it includes:

[0107] comparing the number of curves with the first number of curves and the second number of curves, and determining the initial pressing parameters according to the comparison result; wherein the first number of curves is less than the second number of curves;

[0108] when the number of curves is less than or equal to the first number of curves, the initial pressing parameters are determined as the first pressing parameters;

[0109] when the number of curves is greater than the first number of curves and less than or equal to the second number of curves, the initial pressing parameters are determined as the second pressing parameters;

[0110] when the number of curves is greater than the second number of curves, the initial pressing parameters are determined as the third pressing parameters.

[0111] It can be understood that the initial pressing parameters are in the form of (initial pressing pressure, initial pressing speed); the preferred values corresponding to the first pressing parameters are (P1, V1), the preferred values corresponding to the second pressing parameters are (P2, V2), and the preferred values corresponding to the third pressing parameters are (P3, V3), wherein P1

[0112] Specifically, when determining whether to adjust the initial pressing parameters according to the kneading density change parameter and the material utilization parameter, the following steps are included:

[0113] The kneading density change parameter is analyzed to obtain a density change rate of the current kneading density and the previous kneading density;

[0114] The material utilization parameter is analyzed to obtain a material utilization rate of the material to be formed;

[0115] The density change rate is compared with a density change rate threshold, and the material utilization rate is compared with a material utilization rate threshold, and whether to adjust the initial pressing parameters is determined according to the comparison results;

[0116] If the density change rate is within the density change rate threshold and the material utilization rate is greater than or equal to the material utilization rate threshold, it is determined that the initial pressing parameters are not adjusted;

[0117] Otherwise, it is determined that the initial pressing parameters are adjusted.

[0118] It can be understood that by this way of determining whether to adjust the initial pressing parameters, the actual situation of the material in the forming process can be timely and accurately reflected. The density change rate can directly reflect the change of the tightness of the material in the pressing process. If the density change rate is within a reasonable threshold, it means that the current compaction degree of the material meets the expectation. The material utilization rate reflects the utilization efficiency of the material in the forming process. When the material utilization rate reaches or exceeds the threshold, it means that the waste of the material is within an acceptable range. Only when both conditions are met, it is determined that the initial pressing parameters are not adjusted, which ensures the stability and efficiency of the forming process. On the contrary, if the density change rate exceeds the threshold or the material utilization rate is too low, it means that the current pressing parameters may not meet the forming requirements, and the initial pressing parameters need to be adjusted in time to avoid forming defects and improve the quality and qualification rate of the products.

[0119] Specifically, when adjusting the initial pressing parameters based on the first dust concentration, the second dust concentration, and the environmental parameter to obtain the final pressing parameters, the following steps are included:

[0120] The maximum feeding allowed dust concentration corresponding to the first dust concentration is obtained;

[0121] The maximum pressing allowed dust concentration corresponding to the second dust concentration is obtained;

[0122] respectively calculate a dust deviation degree of the first dust concentration relative to the maximum feeding allowable dust concentration, and a pressing deviation degree of the second dust concentration relative to the maximum pressing allowable dust concentration;

[0123] determine a dust deviation index according to the dust deviation degree and the pressing deviation degree.

[0124] It can be understood that the maximum feeding allowable dust concentration refers to the maximum dust concentration value that can be allowed inside the feeding assembly during the feeding process, which is determined based on the structure, performance and safety production requirements of the feeding assembly. Similarly, the maximum pressing allowable dust concentration is the maximum dust concentration that can be tolerated inside the pressing assembly, which is also determined by considering the working characteristics and environmental protection requirements of the pressing assembly. The dust deviation degree is the percentage of the first dust concentration relative to the maximum feeding allowable dust concentration, which can intuitively reflect the over-standard situation of the dust concentration by comparing the actual dust concentration with the allowable value. The pressing deviation degree is the percentage of the second dust concentration relative to the maximum pressing allowable dust concentration, which reflects the deviation of the dust concentration inside the pressing assembly. The dust deviation index is a comprehensive index obtained by weighted calculation of the dust deviation degree and the pressing deviation degree, which more comprehensively reflects the deviation of the dust concentration in the entire molding process.

[0125] Specifically, when adjusting the initial pressing parameters based on the first dust concentration, the second dust concentration and the environmental parameters to obtain the final pressing parameters, the method further comprises:

[0126] analyzing the environmental parameters to obtain real-time temperature value and real-time humidity value inside the pressing assembly;

[0127] respectively obtaining standard temperature value and standard humidity value corresponding to the real-time temperature value and the real-time humidity value;

[0128] calculating temperature deviation degree of the real-time temperature value relative to the standard temperature value, and calculating humidity deviation degree of the real-time humidity value relative to the standard humidity value;

[0129] determining an environmental deviation index according to the temperature deviation degree and the humidity deviation degree;

[0130] determining an adjustment coefficient of the initial pressing parameters according to the dust deviation index and the environmental deviation index;

[0131] adjusting the initial pressing parameters according to the adjustment coefficient to obtain the final pressing parameters.

[0132] In the embodiment, the standard temperature value and the standard humidity value respectively refer to theoretical optimal temperature value and theoretical optimal humidity value preset according to the material type, the forming specification and the equipment performance parameter of the pressing assembly of the biomass material to be formed in the current forming stage (such as the pre-pressing stage). The standard temperature value is an ideal temperature range for ensuring that the physical properties (such as plasticity and fluidity) of the biomass material are in an optimal state in the pressing process, and the material is not deteriorated (such as decomposition of organic matter in the biomass) due to excessively high temperature or the plasticity of the material is affected due to excessively low temperature. The standard humidity value is a theoretical optimal humidity range for ensuring that the biomass material can be effectively combined and formed in the pressing process, and the material is not stuck to the mold, the water content after forming is out of standard, or the material is brittle and easy to crack due to excessively low humidity.

[0133] It can be understood that the calculation methods of the temperature deviation degree and the humidity deviation degree are the same, that is, the difference between the actual value and the standard value is divided by the standard value, and then multiplied by 100% to obtain the corresponding deviation degree. The environmental deviation index is a comprehensive index obtained by weighted calculation of the temperature deviation degree and the humidity deviation degree, which reflects the deviation of the internal environmental conditions of the pressing assembly from the standard environment. By adjusting the initial pressing parameters with the adjustment coefficient, the final pressing parameters can better adapt to the actual dust concentration and environmental conditions, thereby ensuring the forming quality of the environmental protection products.

[0134] Specifically, when determining the adjustment coefficient of the initial pressing parameters according to the dust deviation index and the environmental deviation index, the following steps are included:

[0135] Obtain the ratio of the dust deviation index to the dust deviation index threshold value, denoted as the dust deviation ratio;

[0136] Set the environmental deviation index threshold value, obtain the ratio of the environmental deviation index to the environmental deviation index threshold value, denoted as the environmental deviation ratio;

[0137] Compare the dust deviation ratio with the dust deviation ratio threshold value, and compare the environmental deviation index with the environmental deviation index threshold value, and determine the adjustment coefficient according to the comparison results;

[0138] When the dust deviation ratio is greater than or equal to the dust deviation ratio threshold value, and the environmental deviation index is greater than or equal to the environmental deviation index threshold value, the adjustment coefficient is determined as the first adjustment coefficient;

[0139] When the dust deviation ratio is greater than or equal to the dust deviation ratio threshold value, and the environmental deviation index is less than the environmental deviation index threshold value, the adjustment coefficient is determined as the second adjustment coefficient;

[0140] When the dust deviation ratio is less than the dust deviation ratio threshold value, and the environmental deviation index is greater than or equal to the environmental deviation index threshold value, the adjustment coefficient is determined as the third adjustment coefficient;

[0141] When the dust deviation ratio is less than the dust deviation ratio threshold value and the environment deviation index is less than the environment deviation index threshold value, the adjustment coefficient is determined as a fourth adjustment coefficient.

[0142] It can be understood that the representation of the adjustment coefficient is (pressure adjustment coefficient, speed adjustment coefficient); the first adjustment coefficient is preferably (a1, b1), the second adjustment coefficient is preferably (a2, b2), the third adjustment coefficient is preferably (a3, b3), and the fourth adjustment coefficient is preferably (a4, b4), wherein a1>a2>a3>a4, b1>b2>b3>b4.

[0143] It can be understood that when the dust deviation ratio is greater than or equal to the dust deviation ratio threshold value and the environment deviation index is greater than or equal to the environment deviation index threshold value, it means that the dust concentration and the environmental condition seriously deviate from the allowable range, and the initial molding parameter is greatly adjusted by using the first adjustment coefficient to adapt to the harsh conditions and ensure the molding quality. When the dust deviation ratio is greater than or equal to the dust deviation ratio threshold value, but the environment deviation index is less than the environment deviation index threshold value, it means that the dust concentration problem is prominent, and the environment condition is good, and the initial molding parameter is appropriately adjusted by using the second adjustment coefficient to take into account the dust problem and the production efficiency. When the dust deviation ratio is less than the dust deviation ratio threshold value, and the environment deviation index is greater than or equal to the environment deviation index threshold value, it means that the environment condition is the main factor affecting the molding, and the initial molding parameter is adjusted by using the third adjustment coefficient to cope with the influence of environmental changes. When the dust deviation ratio is less than the dust deviation ratio threshold value, and the environment deviation index is less than the environment deviation index threshold value, it means that the dust concentration and the environment condition are ideal, and the fourth adjustment coefficient is used for fine adjustment to ensure parameter optimization and not affect the production stability. After the adjustment coefficient is determined, the final molding parameter is calculated according to the formula (initial molding pressure x pressure adjustment coefficient, initial molding speed x speed adjustment coefficient) to make the molding process more scientific and reasonable. Through fine classification and setting of the adjustment coefficient, the initial molding parameter can be flexibly adjusted according to different dust concentrations and environment conditions to improve the molding effect and quality of the environmental protection product molding hydraulic press and ensure the production to be carried out efficiently and stably.
