Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of sand and gravel processing control, and in particular relates to a high-efficiency and environmentally friendly sand and gravel processing control system. Background Art
[0002] The production methods of sand and gravel aggregate are generally divided into wet processing and dry processing. The wet processing technology includes "two-stage crushing (the equipment is jaw crusher + multi-cylinder cone crusher, the multi-cylinder cone crusher performs cyclic crushing and grading adjustment on the aggregate, ensuring the continuity of aggregate grading and particle quality) + one-time screening (using a new 5-layer environmentally friendly vibrating screen to achieve a one-time screening process, which shortens the screening process compared to the traditional 2-3-layer circular vibrating screen) + coarse aggregate shaping (before shaping, the coarse aggregate processed by natural sand and gravel The content of needle-like particles is about 40%~47%. After the natural sand and gravel are crushed and shaped by a vertical shaft crusher, the content of needle-like particles in the coarse aggregate is about 3%~6%) + rod mill sand making (the new JPS200 rod mill has large output, low power consumption, high sand making efficiency, and a sand fineness modulus of about 2.8. The fineness modulus of fine aggregates of natural sand and gravel is about 2.1, and it can be mixed with the JPS200 rod mill to make sand, ensuring that the fineness modulus of the finished sand meets the requirements.)";
[0003] The traditional wet processing industry of sand and gravel generally relies entirely on manual operation or semi-manual operation (manual control + machine quality inspection). The efficiency of manual operation is low. In addition, this method that relies on manpower has significant hidden dangers in terms of safety and is prone to cause workplace accidents. Moreover, due to the inconsistency of operation, the quality of the sand and gravel produced is often not effectively guaranteed. At the same time, the quality inspection standards of manual quality inspection are inconsistent, which makes it difficult to ensure the quality of the final product. If only machine quality inspection is used, only the particle size and appearance of the sand and gravel can be tested, and it is impossible to detect whether its chemical composition contains excessive harmful substances, and the safety of the product cannot be guaranteed.

[0075] In this embodiment, the inventory is the existing effective inventory of the aggregate warehouse with the specifications required by the customer.
[0076] In this embodiment, the loss amount refers to the aggregate loss amount during the processing, storage and transportation of the batch of aggregate.
[0077] In this embodiment, the types of rough raw materials include river sand and gravel, drilled and blasted materials, TBM materials, and the like.
[0078] In this embodiment, the processing workshop includes a coarse crushing workshop, a medium crushing workshop, a screening workshop, a rod mill workshop and a regulating silo, a shaping workshop and a finished aggregate silo.
[0079] In this embodiment, the processing equipment includes a coarse crushing workshop which can select an HPJ80 jaw crusher, a medium crushing workshop which can select an HPM4000 cone crusher, a screening workshop which can select a 5SLS2565 environmentally friendly vibrating screen, a rod mill workshop which can select a JPS200 rod mill and a GZG90-150 vibrating feeder, and a shaping workshop which can select a YKR1845 circular vibrating screen and a ROR6000 vertical shaft crusher.
[0080] In this embodiment, each processing workshop is controlled to process the rough raw materials. The processing process includes loading the rough raw materials into dump trucks at the material yard by excavators and transporting them to the coarse crushing workshop for the first stage of crushing. The coarse crushing workshop uses an HPJ80 jaw crusher. The crushed aggregates directly enter the screening workshop for screening. The screening workshop is equipped with a 5SLS2565 multi-layer vibrating environmental protection screen. The screened qualified aggregates are directly stored in the warehouse, and the unqualified aggregates are returned to the secondary crushing workshop. The secondary crushing workshop is equipped with an HPM4000 cone crusher and a transfer silo with a capacity of 180m³ to ensure the continuous full cavity operation of the cone crusher. The aggregates crushed by the secondary crushing are mixed with the aggregates crushed by the coarse crushing workshop and enter the screening workshop for screening together. The two stages of crushing form a closed loop.
[0081] The machine-made sand particles after screening in the screening workshop are washed by an FC15 spiral sand washer to remove excess mud powder, and finally dehydrated by a ZKR1845 linear screen and stored in the warehouse;
[0082] In order to ensure that the particle shape and quality of some finished crushed stones meet the specification requirements, a shaping workshop is set up, equipped with a ROR6000 vertical impact crusher, which mainly shapes 5-10mm and some 10-20mm crushed stones.

The silo volume is 180m³. In the absence of material source replenishment, it can continuously produce for about 1h.
[0084] In this embodiment, the wastewater purification process is a mechanical pretreatment → water collection tank → fine sand recovery workstation → inclined plate thickener → high-pressure diaphragm filter press process;

[0086] The specific operation of wastewater purification is as follows: the collection tank recycles the sewage and the thickener concentrates the mud. The sewage generated by the rod mill workshop, screening and shaping workshop enters the collection tank, and the sewage in the collection tank is pumped to the cyclone on the top of the thickener by a slurry pump. The top sewage enters the thickener and is equipped with two conical inclined plate sludge hoppers. The sludge is circulated and alternately precipitated to the bottom of the conical mud hopper. The concentrated sludge is pumped to the high-pressure diaphragm filter press by a slurry pump and pressed into mud cake, which is transported to the waste dump by a dump truck for natural drying. The bottom sewage after cyclone treatment enters the fine sand recovery integrated machine for dehydration and then enters the warehouse. At the same time, the overflow clean water on the top of the thickener enters the clean water recovery tank, forming a closed loop as a whole.
[0087] In this embodiment, the physical online detection is the detection of the particle size and shape of the finished aggregate, and the chemical online detection is the detection of the methylene blue and chloride ion content of the finished aggregate.
[0088] In this embodiment, the real-time operation status of each processing workshop includes normal operation and abnormal operation.
[0089] The working principle and beneficial effects of the above technical solution are as follows: the present invention realizes the intelligent and environmentally friendly production process through a series of modular designs. The system first uses the production demand determination module to accurately calculate the final production demand of the required specification aggregate based on the customer's specification requirements, inventory and loss. Then, in the blank raw material determination module, the system can determine the required blank raw material type, ratio and corresponding weight according to the calculated demand to ensure the rational use of raw materials. In the processing stage, the processing workshop control module selects appropriate equipment and processing flow based on the customer's delivery time and aggregate demand to ensure that each processing workshop efficiently processes the blank raw materials. In order to achieve real-time The system monitors and evaluates the performance of each processing workshop. The system also integrates a processing workshop fault assessment module, which can collect the discharge efficiency and semi-finished product qualification of each workshop, and evaluate the real-time operation status through a comprehensive evaluation matrix to improve the reliability and stability of production. In terms of environmental protection, the environmental monitoring and processing module monitors and purifies the dust, noise and wastewater generated during the processing in real time to ensure that environmental protection standards are met. In addition, the finished aggregate online detection module performs physical and chemical online detection before the finished product enters the warehouse, including physical detection of particle size and shape and chemical detection of methylene blue and chloride ion content, so as to comprehensively judge the qualification of the finished aggregate, which can effectively control the quality of the finished aggregate out of the factory;
[0090] The present invention realizes the intelligent control of sand and gravel production. At the same time, the physical online detection of finished aggregates detects the particle size and shape of the finished aggregates, and the chemical online detection detects the harmful substances chloride and methylene blue value in the finished aggregates, which improves the detection efficiency, reduces the labor intensity of testers, realizes the online collection, real-time detection, remote analysis and dynamic feedback of finished aggregates, and improves the quality control level of finished aggregates.

[0096] The production requirement finalization determination unit is used to determine the final production requirement of the aggregate of the specification required by the customer based on the weight of the aggregate of the specification required by the customer, the existing effective inventory of the aggregate of the specification required by the customer in the warehouse, and the comprehensive loss of the aggregate of the specification required by the customer in the production process.
[0097] In this embodiment, the specifications of the aggregate include large stone (16-31.5 mm), medium stone (10-20 mm), small stone (5-10 mm) and sand (<5 mm).
[0098] In this embodiment, the existing effective inventory of aggregates of the specifications required by the customer is the aggregates of qualified quality among the aggregates of the specifications required by the customer, that is, the aggregates with high moisture or large amount of impurities are excluded.
[0099] In this embodiment, the loss coefficient includes a crushed stone processing loss reserve coefficient, a sand processing loss reserve coefficient, and a storage and transportation loss coefficient;
[0100] The crushed stones include large stones (16-31.5mm), medium stones (10-20mm) and small stones (5-10mm), and the sand is sand (<5mm).
[0101] In this embodiment, the comprehensive loss amount in the production process of the aggregate of the specifications required by the customer is the sum of the loss in the process of producing the aggregate of the specifications required by the customer and the loss of the aggregate during storage and transportation.
[0102] The working principle and beneficial effects of the above technical solution are as follows: the customer demand determination unit is used to clarify the specifications of the aggregates required by the customer (such as large stone, medium stone, small stone and sand) and their weight; the inventory verification unit is responsible for real-time verification of the existing effective inventory in the warehouse so as to calculate only the aggregates of qualified quality; the loss determination unit accurately calculates the comprehensive loss of the aggregates of the specifications required by the customer based on the loss coefficients set during the processing, storage and transportation of aggregates of different specifications; and the production demand final determination unit combines the weight of the aggregates required by the customer, the existing inventory and the comprehensive loss, and finally determines the production demand of the aggregates of the specifications required by the customer, thereby improving the accuracy of the sand and gravel aggregate production process.
[0103] Example 3
[0104] Based on Example 2, the comprehensive loss of aggregates in the production process of the specifications required by the customer is:
[0105] (1); among which, The comprehensive loss in the production process of aggregates of the specifications required by customers, The weight of aggregates of the specifications required by customers, is the current effective inventory of aggregates of the specifications required by customers, e is a natural number, and its value is 2.71. is the reserve coefficient for the loss of crushed stone or the reserve coefficient for the loss of sand. is the storage and transportation loss coefficient.
[0106] In this embodiment, the gravel processing loss reserve coefficient is usually taken as 1.06, the sand processing loss reserve coefficient is usually taken as 1.33, and the storage and transportation loss coefficient (i.e. the loss of gravel or sand finished products during storage and transportation, usually takes a value of 1.04-2.8).
[0107] The working principle and beneficial effects of the above technical solution are: the accurate calculation of the comprehensive loss amount in the production process of aggregates of the specifications required by customers not only ensures that the use of materials in the production process is more scientific and reasonable, reduces unnecessary waste of resources, but also improves the speed and accuracy of responding to customer needs.

[0111] Otherwise, calculate the final production demand of aggregates of the specifications required by the customer;
[0112] The production demand calculation subunit is used to calculate the final production demand of aggregates of the specifications required by customers. .
[0113] In this embodiment, the calculated compensation weight of the aggregate is 0.5-1.2 tons.
[0114] The working principle and beneficial effects of the above technical solution: By introducing the judgment subunit and the production demand calculation subunit, precise control of the production demand of aggregates of the specifications required by customers is achieved. The judgment subunit first compares the weight of the aggregates of the specifications required by customers with the existing effective inventory in the warehouse. If the inventory is greater than the demand, the system will automatically set the final production demand of the aggregates of the specifications required by customers to 0 to avoid unnecessary product accumulation. At the same time, the aggregate calculation compensation weight is introduced to ensure that potential demand fluctuations or errors can be effectively responded to in actual operations. If the inventory is insufficient, the system will enter the calculation stage, using the relevant loss coefficient and inventory information to accurately calculate the final production demand of the aggregates of the specifications required by customers, which not only improves the response speed and resource utilization efficiency of the production process, but also effectively reduces inventory pressure.
