Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of porcelain insulator manufacturing, and particularly relates to a slurry-making and granulating platform for raw porcelain mud output in the raw material processing stage of porcelain insulators. BACKGROUND

[0002] As a core component of high-voltage transmission lines, porcelain insulators bear the dual functions of insulation support and mechanical connection, and their preparation process directly affects the safety and reliability of power grid operation. The conventional porcelain insulator preparation process mainly includes four key stages: raw material selection and proportioning → mud making and shaping → glazing and firing → assembly and detection. Among them, the mud making link is the core link connecting raw materials and shaping, and has a decisive influence on the mechanical strength, insulation performance and appearance quality of the final product.

[0003] The porcelain mud slurry-making process usually covers wet grinding, ball milling, iron removal by sieving, etc. After being proportioned, the raw materials (such as quartz, feldspar, clay) are preliminarily mixed by a wet grinding machine, then ground to fine particles by a ball mill, and then the qualified mud slurry is obtained after removing impurities and iron filings by sieving, and the qualified mud slurry can be sent to the next process for mud refining. The core goal of this process is to obtain porcelain mud with high uniformity and good plasticity, providing a basis for subsequent rotary blank or compression molding. If the porcelain mud has uneven particles or bubbles, it will cause defects such as cracking of insulator blank body and insufficient mechanical strength, and even cause power grid accidents.

[0004] In the prior art, the slurry-making process of "mixing new slurry with old slurry" is widely considered as a better solution to improve the performance of porcelain mud, and its core principle is to mix the newly prepared porcelain slurry with the recycled old slurry generated in the previous production according to a certain proportion. This process has multiple advantages: it can improve resource utilization, recycle the raw materials that have not been fully utilized in the old slurry, reduce waste emissions, and meet environmental protection requirements; it can make the slurry performance more stable, the old slurry has been treated in the previous stage, and the particle distribution and moisture content are more uniform, and after mixing with the new slurry, the performance fluctuation of the new slurry can be reduced; it can reduce production cost and reduce the amount of new raw materials; it can enhance process adaptability, and the plasticity and fluidity of the mixed slurry are more easily controlled.

[0005] However, the existing equipment suitable for the "mixing new slurry with old slurry" process generally adopts a dispersed arrangement or a linear arrangement, and these two types of equipment layout have significant defects in the repeated mixing and processing of the slurry-making process: 1. Low material transportation efficiency, linear arrangement leads to long-distance transportation of new slurry and old slurry between multiple devices, and repeated handling increases energy consumption and time cost; 2. The mixing process in the linear process is only performed once, and it is difficult to achieve sufficient fusion of the new slurry and the old slurry, and repeated pipeline transportation can also lead to insufficient mixing uniformity, which may introduce impurities, reduce product yield, and affect the stability of porcelain mud quality; Third, the space occupation is large, and the flexibility is poor, the equipment is arranged in a straight line, and a large factory space is needed, which is not conducive to the compact design of the production line; if the mixing ratio needs to be adjusted or the processing procedure is increased, the linear layout is difficult to quickly reconfigure, which restricts the process optimization.

[0006] In summary, the porcelain mud slurry process is a key link in the production of porcelain insulators. Although the "new slurry mixed with old slurry" process can improve performance and economy, the existing linearly arranged equipment cannot meet the high-efficiency and stable production requirements. Therefore, a new type of slurry preparation platform is urgently needed to optimize the equipment layout and material flow to solve the above technical defects. SUMMARY

[0007] The technical problem solved by the present application is to provide a porcelain mud slurry preparation platform for porcelain insulators, aiming to solve the problem of low efficiency caused by unreasonable equipment arrangement in the existing slurry preparation process. Through the spatial layout of the platform structure, efficient connection of the whole process of porcelain mud preparation is realized, and the stability and resource utilization rate of porcelain mud preparation are improved to solve the defects of the above technical background.

[0008] The technical problem solved by the present application is solved by the following technical solution: A porcelain mud slurry preparation platform for porcelain insulators is a vertically integrated multi-layer slurry preparation platform, including an underground layer and a ground three-layer structure: A mixed mud pool and a qualified mud pool are arranged in the space of the underground layer; A mud processing assembly is arranged in the space of the ground layer, the mud processing assembly is a combination of a vibrating screen and a permanent magnet iron remover, the vibrating screen is in front, and the permanent magnet iron remover is in back; A new slurry pool and an old slurry pool are arranged in the space of the ground second layer; A mud stirring device is arranged in the space of the ground third layer; The new slurry pool and the old slurry pool are respectively connected to the mixed mud pool through independent gravity self-flow pipelines, the mixed mud pool is connected to the mud stirring device through a pumping pipeline, the discharge end of the mud stirring device is connected to the mud processing assembly through a gravity self-flow pipeline, and the discharge end of the mud processing assembly is connected to the qualified mud pool through a gravity self-flow pipeline.

[0009] As a further limitation, the gravity self-flow pipelines connected to the new slurry pool, the old slurry pool, the mud stirring device, and the mud processing assembly are provided with flow meters and electric control valves.

[0010] As a further limitation, a vibrating screen is arranged on the gravity self-flow pipeline connected to the new slurry pool and the gravity self-flow pipeline connected to the old slurry pool.

[0011] As a further limitation, the vibrating screen in the mud processing assembly is preferably a multi-stage vibrating screen.

[0012] As a further limitation, the new slurry tank, the old slurry tank, the mixed slurry tank and the qualified slurry tank are each provided with a separate stirring device to prevent the slurry from settling through continuous stirring of the stirring device.

[0013] As a further limitation, the front end of the new slurry tank is connected to a ball milling pulping device.

[0014] As a further limitation, the old slurry tank is provided with a water content dynamic monitoring device to monitor the water content of the old slurry in the old slurry tank in real time; the old slurry tank is also provided with a back wheel excess material powder supply device and a water supply pipe, so that when the water content value of the old slurry measured by the water content dynamic monitoring device is too large or too small, the water content of the old slurry can be accurately controlled to the process requirement range by adding an appropriate amount of excess material powder through the back wheel excess material powder supply device or supplementing water through the water supply pipe.

[0015] Beneficial effects: The present application provides a porcelain mud pulping platform for porcelain insulators, which integrates key equipment and processes in the whole pulping process in a multi-layer structure design. This multi-layer layout significantly shortens the material transportation distance, effectively reducing the overall pulping cycle time. In addition, the multi-layer layout can also cooperate with the self-flow pipeline to reduce the use of pumping devices, reducing material loss caused by pipeline residues, improving resource utilization, and reducing material consumption. In addition, this spatial layout is also convenient for integrated control through the control system, which is conducive to realizing the automation of the whole process of batching, stirring, conveying, detection and the like.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, purposes and effects realized by the present application easy to understand, the present application is further described below in combination with specific drawings.

[0019] In the following examples, those skilled in the art can understand that, unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs. It should also be understood that terms such as those defined in general dictionaries should be understood to have meanings consistent with those in the prior art, and should not be interpreted with idealized or overly formal meanings unless defined as such.

[0020] Referring to Figure 1 A porcelain mud slurry platform for porcelain insulators, in the present embodiment, the porcelain mud slurry platform is a vertically integrated multi-layer slurry platform, which builds a spatial layout of 1 layer underground + 3 layers above ground through a steel frame structure platform, and uses the steel frame platform as a bearing layer plate 2. The equipment area uses anti-skid wear-resistant floor and stainless steel guardrails to meet the safety specifications of industrial production, and realizes efficient connection, quality control and environmentally friendly operation of the whole process of porcelain mud preparation.

[0021] In the present embodiment, the underground first layer is a sunken space below the foundation 5, and a mixed mud pool 14 and a qualified mud pool 15 are arranged in the space. The surface of the underground first layer corresponding to the foundation 5 is face-closed by a bearing plate, and is required to bear the functions of mud mixing homogeneity and qualified product storage.

[0022] The ground first layer is a core processing area, which realizes the filtration, iron removal and high-pressure conveying of mud. A mud processing assembly is arranged in the space, which adopts a combined layout of a vibrating screen II 12 and a permanent magnet iron remover 13. The vibrating screen II 12 is a three-stage vibrating screen used for size grading and screening of mud through a multi-stage screen structure, effectively intercepting impurity particles with oversized particle size. The permanent magnet iron remover 13 connected in series at the rear end adopts a strong magnetic adsorption principle and can efficiently separate the residual ferromagnetic particles in the mud. This front-rear series processing mode not only ensures the uniformity of the particle size of the mud, but also ensures the complete removal of ferromagnetic impurities, providing high-quality mud meeting the process standards for subsequent processes.

[0023] In addition, the ground first layer of the present embodiment also reserves a mounting space for the plunger pump 4.

[0024] The ground second layer is a raw material fine processing and storage area, and a new slurry pool 9 and an old slurry pool 10 are arranged in the space. The new slurry pool 9 is used to receive the newly prepared slurry produced by the ball mill slurry preparation equipment, and the old slurry pool 10 is used to collect the recycled old slurry in the previous production.

[0025] In the present embodiment, the new slurry pool 9, the old slurry pool 10, the mixed mud pool 14 and the qualified mud pool 15 all adopt a sealed design and are equipped with independent stirring devices to prevent mud from settling and caking.

[0026] The ground three layers are high-efficiency mixing zones, and a mud stirring device 8 is arranged in the space, which is a stainless steel stirring barrel in the embodiment, and a high-torque stirring paddle and a variable frequency motor are combined, so that the stirring intensity and time can be flexibly adjusted according to the proportioning requirements of new slurry and old slurry, and the two kinds of slurry are fully mixed in the mixing mud pool 14.

[0027] The new slurry pool 9 of the embodiment adopts ball mill to prepare new slurry, and the ball mill is fed after the slurry material is prepared, and the slurry is pumped to the new slurry pool 9 through a slurry pump when the fineness of the ball mill reaches the qualified level. The old slurry pool 10 is used to recycle the return wheel slurry returned from the forming process. Considering that the water content of the return wheel slurry may fluctuate due to differences in production links, the old slurry pool 10 is used to receive the old slurry in the return wheel slurry pool. The return wheel slurry pool controls the water content by the following method: first, add excess water in the old slurry pool 10, then add some excess material powder, and mix uniformly until the water content of the slurry in the old slurry pool 10 is qualified, and then pump it to the old slurry pool 10.

[0028] In other embodiments, the old slurry pool 10 can be provided with a return wheel excess material powder supply device and a water supply pipe, and be equipped with a water content dynamic monitoring device. The water content of the old slurry can be accurately mastered through real-time data feedback. When the water content dynamic monitoring device detects that the water content of the old slurry exceeds the process requirement range, the system will automatically start the adjustment program: if the water content is too high, the water content will be supplemented according to the preset proportion through the water supply pipe, and the stirring device in the old slurry pool will be started to accelerate the mixing; if the water content is too low, dry excess material powder will be added quantitatively through the return wheel excess material powder supply device, and the powder and slurry will be fully mixed through multi-stage stirring. The closed-loop control system can also correct the parameters of the old slurry in the old slurry pool 10 in real time, so that the water content is stable within the process allowable deviation range, and provides quality stable raw material guarantee for the subsequent mixing of new and old slurry.

[0029] The new slurry pool 9 and the old slurry pool 10 are connected to the mixing mud pool 14 in the underground first layer through independent first gravity self-flow pipeline 3 and second gravity self-flow pipeline 7 respectively. The new and old slurry in the new slurry pool 9 and the old slurry pool 10 are proportioned when used, accurately controlled through a mass flow meter and a proportional valve, and enter the respective vibrating screen I 11 in a gravity self-flow manner through the first gravity self-flow pipeline 3 and the second gravity self-flow pipeline 7 for screening. The proportioned slurry after screening is sent to the mud mixing pool 14.

[0030] The mud in the mud mixing pool 14 is connected to the plunger pump 4 through the pumping pipeline 1, and is transported to the mud stirring device 8 on the ground three layers under the high-pressure drive of the plunger pump 4. The mud stirring device 8 fully mixes the new and old slurry through the rotation of the high-torque stirring paddle. The stirring speed and time can be adjusted according to the process requirements during the stirring process, so that the uniformity of the slurry reaches the best state.

[0031] The mixed mud is transported to the mud processing assembly of the ground layer through the third gravity self-flow pipeline 6 connected to the bottom of the mud stirring device 8. First, it enters the vibrating screen II 12 for multi-stage particle size screening, effectively intercepting large-particle impurities; then it flows into the permanent magnet iron remover 13, which removes residual ferromagnetic particles through a strong magnetic field. The qualified mud filtered and de-ironed is finally transported to the qualified mud pool 15 of the underground layer for storage, waiting for the next process.

[0032] In this embodiment, the mud in the qualified mud pool 15 is pumped to the spray granulation tower by the plunger, granulated in the spray granulation tower, and the finished particles are lifted to the silo by the lifting belt after being screened by the vibrating screen.

[0033] In this embodiment, the whole slurry preparation process adopts a transmission mode of gravity self-flow and pumping cooperation, combined with multi-layer space layout design, to realize the efficiency and energy saving of material flow. At the same time, through the design of sealed pool body and closed-loop control system, the stability of mud quality and the precision controllability of process parameters are ensured. In addition, the cooperation of gravity self-flow design and pumping pipeline structure effectively reduces the pumping energy consumption and reduces the raw material loss caused by pipeline residue.

[0034] Through the above structure design and equipment configuration, the present application realizes the vertical integration and automatic control of the whole process of porcelain mud preparation, significantly improves the slurry preparation efficiency and the stability of product quality.

[0035] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
