Detailed Description
The following detailed description is made with reference to the accompanying drawings.
According to the stirring building in the prior art, under the condition of the same storage capacity of the storage bins, the storage bins of the stirring building are unreasonably arranged, the occupied space is large, the size is large, and dust is serious.
The invention provides a novel stirring building for distributing and storing aggregate, and also provides an aggregate distributing and storing method for the stirring building. The mixing plant of the invention is a concrete mixing plant or a dry powder mortar mixing plant.
The invention relates to a novel mixing building for aggregate distribution and storage, which at least comprises an integrated frame 1 and at least one bin arranged at the top of the frame 1, as shown in figure 1. The frame 1 is an i-steel frame beam structure for fixing each component inside the frame 1. The silo comprises a powder silo 2 and an aggregate silo 6. The supporting structures of the filler silo 2 and the aggregate silo 6 are all located in the same plane formed by the top of the frame. That is, the powder bin 2 and the aggregate bin 6 are disposed on the same horizontal plane. The filler bin 2 and the aggregate bin 6 are at the same height. So set up, be favorable to sparingly stirring building occupation space in vertical direction.
At least one adhesive tape separating machine 18 is arranged on the plane of the feed inlet of the storage bin. The vertical height of the material separating tape machine 18 is lower than the discharge hole of the transition receiving hopper 15, so that the premixed material transferred to the transition receiving hopper 15 by the material feeding tape machine 14 is quantitatively transferred to the aggregate bin 6 or the powder bin 2. Wherein, the adhesive tape dispenser 18 is provided with a rotating mechanism rotating around the center thereof. The rotating mechanism is, for example, a rotatable shaft that can be rotated in the reverse direction. The rotating shaft is connected with the rotating control component, so that the rotating angle of the material distributing adhesive tape machine is adjusted, and the pre-mixed material is quantitatively transmitted to the aggregate bin 6 or the powder bin 2. The rotation control assembly includes a rotation motor connected to the rotation shaft as long as a mechanical structure capable of realizing the control of the rotation angle of the rotation shaft. Preferably, the rotating shaft is not disposed at the horizontal center of the adhesive tape dispenser 18, and is disposed at a position deviated from the center so that one end of the adhesive tape dispenser 18 can extend to the range of the material inlet of the aggregate bin, and the other end of the adhesive tape dispenser 18 can extend to the range of the material inlet of the aggregate bin. The distributing adhesive tape machine 18 in fig. 1 is a linear distributing adhesive tape machine, and the off-center arrangement is advantageous in that the material can be fed to powder bins or aggregate bins at different distances without adjusting the length of the distributing adhesive tape machine 18.
Preferably, the aggregate bins 6 include sand and stone bins. The aggregate bin is used for containing coarse aggregate and/or sand fine aggregate. The sand aggregate bin is circumferentially divided into at least one storage grid. The stone aggregate bin is circumferentially divided into at least one storage grid, so that aggregates of various different types can be stored. For example, the sand aggregate bin is circumferentially divided into 3 storage grids. The stone aggregate bin is circumferentially divided into 2 storage grids, and 5 different types of aggregates can be stored. Rotate to different storage check tops through dividing the material sealing-tape machine to control direction of transfer, carry different aggregate to in different storage check.
Among the prior art, in actual stirring building construction engineering, square feed bin structure is the burst structure, and the bolt concatenation needs to be used at the scene, has the processing degree of difficulty great, the longer problem of man-hour. For example, a 300-cube square aggregate bin needs to be processed into a slicing structure in advance and then is transported to the site for assembly and hoisting, and the whole process needs 5 persons to work for four days, so that the problems of high processing difficulty and long working hours exist. Preferably, the powder bin 2, the sand aggregate bin 61 and the stone aggregate bin 62 are all circular in shape, and have the same diameter or similar diameter size, so that the purposes and the number of the bins can be adjusted more flexibly, and the universalization and the standardized design of products are utilized. For the same square bin volume, the round bin can be manufactured and assembled on site, and the installation and hoisting time on site after the manufacturing is finished only needs 2 persons to work for half a day. The time for installation and hoisting on site after the manufacture is completed is greatly shortened, so that the problem of long time for saving labor by adopting a circular stock bin is solved, and the emergency engineering effect is very obvious.
As shown in fig. 2, the powder bin 2, the sand aggregate bin 61 and the stone aggregate bin 62 are arranged in a matrix array, which is beneficial to reducing the occupied space of the bins. Wherein the sand silo 61 and the stone silo 62 are arranged in the position of the central row/column of at least one direction of the silo matrix. I.e. the second silo is arranged in the central row/column of the silo matrix. And, the sand silo 61 or the stone silo 62 in the first silo 6 is arranged at one end of the central row/column, as shown in fig. 2. The bin matrix of the present invention is not limited to the 3 × 3 array shown in fig. 2, and may be another M × N array, or M ≠ N. The size and the array shape of the bin matrix can be flexibly set on the basis of the field, the overall arrangement is convenient, the use and the number of the bins can be more flexibly adjusted, and the universalization and the standardized design of products are utilized. The plurality of material bins are round, so that the problem of long time can be solved, and the emergency engineering effect is quite obvious; meanwhile, the utilization rate of the round aggregate bin is higher than that of the rectangular-section aggregate bin of the conventional stirring building.
As shown in fig. 2, a plurality of small-sized storage bins 22 are provided in the space between the powder bin, the sand bin 61 and the stone bin 62. To simplify the drawing, only 1 storage bin 22 is shown in fig. 2, actually comprising several storage bins 22. The storage bin is used for storing water, liquid additives or powdery additives. The stirring tower has compact structure and small occupied area. The landing leg of storage storehouse 22 is connected with the feed bin landing leg respectively in order to support, alternates in second feed bin 6 and 2 neutral gear departments of first feed bin, and storage storehouse 22 need not do alone and support, simplifies the structure, saves space, practices thrift the cost. The landing leg of storage storehouse 22 is connected with the feed bin landing leg respectively in order to regard as the support, alternates in second feed bin 6 and 2 neutral gear departments of first feed bin, and storage storehouse 22 need not do and support alone, simplifies the structure, saves space, practices thrift the cost.
As shown in figure 1, the bottom of the storage bin is of an inverted cone structure, so that materials can be discharged and conveyed from the bottom of the storage bin conveniently. At least one inserting plate door 23 for adjusting the discharging speed of the sand aggregate is arranged at the discharging port at the bottom of the sand aggregate bin 61. The discharge of aggregate can be controlled by adjusting the gate 23. The gate 23 is connected to the controller. The larger the movement amplitude of the inserting plate door 23 is, the larger the discharging area of the discharging port is, and the faster the sand aggregate discharging speed is. On the contrary, the discharging speed of the sand aggregate is reduced. In the case where the gate 23 completely closes the discharge port, no sand aggregate flows out. The advantage of the provision of the gate 23 is that the sand batching tape machine 19 can be serviced without emptying the silo aggregate,
at least one sand batching adhesive tape machine 19 for conveying the sunning batching is arranged at the bottom of the sand aggregate bin 61. Wherein, sand batching sealing-tape machine 19 sets up in the vertical below of picture peg door 23. The sand aggregate is discharged from the bottom of the sand aggregate bin 61 and falls on the sand batching tape machine 19. The sand batching tape machine 19 conveys the aggregates into the first weighing device 7. A turning plate 25 is arranged between the sand batching adhesive tape machine 19 and the first weighing device 7 and is used for preventing sand aggregate from splashing.
The discharge hole at the bottom of the stone aggregate bin 62 is provided with at least one arc-shaped door 3 for conveying stone aggregate ingredients. The stone aggregate is discharged quantitatively into the second weighing device 8 through the opening and closing of the arc door 3. Wherein stone aggregates are transported into the second weighing device 8 by means of an air transport chute (not shown in the figure). The air conveying chute is a continuous pneumatic conveying device for conveying dry materials (such as cement, aggregate and the like) obliquely downwards.
The first weighing device 7 and the second weighing device 8 are both connected with the inlet of the concrete mixer. Preferably, the switch of the sand batching tape machine 19 and the switch of the arc-shaped door 3 are both connected with the controller. Under the condition that the weight value of the first weighing device 7 and the weight value of the second weighing device 8 reach the preset weight value or reach the preset weight ratio value respectively, the controller controls the inserting plate door 23 and the arc-shaped door 3 to be closed, and controls the sand batching adhesive tape machine 19 to pause, so that the weighed stone aggregate and sand aggregate are conveyed to be mixed with the powder.
In use, the loading adhesive tape machine 14 transports aggregates or powder into the transition hopper 15, and corresponding premix is conveyed into the aggregate bin 6 or the powder bin 2 through the distributing adhesive tape machine 18 according to the positions of the powder bin 2 and the aggregate bin 6. When concrete is needed, the silo 2 and the silo 6 are opened. Wherein the sand aggregate is conveyed into the first weighing device 7 by a sand batching belt machine 19. The stone aggregates are conveyed into the second weighing device 8 through the air conveying chute, and the aggregates with corresponding weight and proportion are weighed.
The dust-proof device in the prior art is a common dust-proof net. The dust screen reduces the filtering effect gradually along with the extension of live time. Under the condition that the filtering effect is tiny, the dust screen is not replaced in time, and the environment where the stirring building is located can quickly become poor and is full of dust. If the dustproof net is replaced under the condition of having the dustproof effect, the dustproof cost is higher. Especially for the filter screen with good dustproof effect such as nano fiber filter screen, the dustproof screen mainly aiming at human health, the replacement cost is higher. How to change the dust screen at the right time to reduce the dust-proof cost is a technical problem which is not further solved by the prior art.
As shown in figure 1, the invention is also provided with an intelligent dust removal system. The intelligent dust removal system comprises an intelligent dust screen, an electrical property monitoring unit and a data processing unit. The electrical performance monitoring unit is connected with the data processing unit. The data processing unit is connected with the controller. The intelligent dust screen comprises at least a first nanofiber screen 26 and a second nanofiber screen 27.
The first nanofiber filter screen 26 is disposed in a space where the discharge port of the filter funnel 15, the material separating tape machine 18 and the material inlet of the powder bin 2 are located. Namely, the first nanofiber filter screen 26 hermetically surrounds the discharge port of the filter funnel 15, the moving space of the adhesive tape dispenser 18 and the feed port of the powder bin 2, so as to filter the dust of the materials.
The second nanofiber filter screen 27 is arranged around the space where the discharge port of the sand aggregate bin 61, the discharge port of the stone aggregate bin 62, the movable space of the sand batching tape machine 19, the feed port of the first weighing device 7 and the feed port of the second weighing device 8 are located. That is, the second nanofiber filter screen 27 seals and surrounds the discharge hole of the sand aggregate bin 61, the discharge hole of the stone aggregate bin 62, the moving space of the sand batching tape machine 19, and the space where the feeding hole of the first weighing device 7 and the feeding hole of the second weighing device 8 are located, so as to filter the dust of the materials.
The first nanofiber filter screen 26 and the second nanofiber filter screen 27 have the same structure, are both silver-containing nanofiber filter screens, and the main body of the nanofiber filter screen is a nanofiber filter screen containing silver ions and/or silver nanowire components, so that particles, especially virus particles, can be filtered based on smaller pore sizes.
Silver in the nanofiber filter screen can easily generate monovalent silver ions Ag on the surface when meeting water+On the other hand, the silver oxide is easily oxidized in the air to generate silver oxide AgO, and under the action of water, the silver oxide is hydrolyzed to generate divalent silver ions Ag2+And hydroxyl. The two silver ions can be rapidly combined with enzyme protein in the thallus, so that the enzyme loses activity and the metabolism process of biomolecules is destroyed. After the reaction, a part of silver ions are dissociated from dead bacteria and continue to be sterilized, and meanwhile, a part of silver ions are remained in the dead bacteria and exist in the form of a silver-biomolecule compound. With the continuous contact with the thallus, the silver ions are continuously lost, so the reaction of silver oxidized into silver ions is continuously carried out to realize chemical equilibrium, and the silver content is reduced. Because the conductive main body in the nanofiber filter screen is silver, the conductivity of the nanofiber filter screen tends to be gradually reduced along with the increase of the oxidation degree of the silver and the gradual reduction of the content of the silver, and the sterilization efficiency also tends to be reduced. Thus, a linear relationship of the electrical performance parameter to the degree of silver oxidation can be obtained by several tests. The correlation is in accordance with a pattern of a ═ xB, and specific values of x are obtained by the test. The degree of silver oxidation can also reflect the degree of silver loss. The silver oxidation degree and the sterilization efficiency have a correlation relationship, and the correlation coefficient can be obtained through testing. The correlation corresponds to a pattern of a ═ yB, and specific values of y are obtained by testing. Further, sulfur dioxide and nitrogen dioxide present in the air readily react in the air and combine with fine particulates to form sulfuric acid mist, photochemicallyChemical smog and other acidic smog. After the acid smoke passes through the nanofiber filter screen, silver is easily oxidized, and then the conductivity of the film is reduced. And obtaining the corresponding relation between the dustproof quality grade and the electrical property parameter change rate by detecting the electrical property parameter change rate of the nanofiber filter screen within a certain time and the air quality. Accordingly, a parameter or level of dust-proof quality can be evaluated based on the rate of change of the electrical property parameter. The nanofiber filter screen can filter fine particles such as viruses and bacteria in the air, and the sterilization efficiency parameter of the nanofiber filter screen to the air is determined according to the silver oxidation degree or the loss degree of the viruses to the silver nanowires. The higher the sterilization efficiency parameter is, the higher the air quality parameter through the nanofiber filter screen is, and the higher the dustproof quality is. Therefore, the invention monitors the dustproof quality by monitoring the filtering state of the nanofiber filter screen.
The electrical property monitoring unit in the present invention refers to a circuit or an integrated circuit capable of monitoring electrical property parameters of the nanofiber filter, or a component capable of directly calculating required electrical property parameters, such as a current testing component, a voltage testing component, a resistance testing component, a magnetic flux, a magnetic induction intensity testing component, and the like. The electrical property parameters of the invention include not only resistance, current, voltage, magnetic flux and magnetic induction related to electromagnetic induction, but also any parameter calculated based on resistance, current, voltage, magnetic flux and magnetic induction. At least one electrical property monitoring unit is disposed on the first nanofiber screen 26, the second nanofiber screen 27, respectively, and in direct contact with the silver material of the nanofiber screen to acquire electrical property parameters on the nanofiber screen.
The data processor in the present invention may be a computer, a server, etc. The data processing unit calculates a filtration state parameter of the nanofiber filter screen related to the dustproof quality parameter based on the electrical property parameter of the silver structure portion of the nanofiber filter screen acquired by the electrical property monitoring unit, so that the dustproof quality parameter after filtration is evaluated based on the filtration state parameter. Under the condition that dustproof quality is low to not have the filter effect, the staff in time changes the nanofiber filter screen to guaranteed the dust removal effect of stirring building, also protected that the staff's is healthy, avoided the lung damage of raise dust.
In the case where the controller has a data processing function, the controller can be directly connected to the electrical property monitoring unit without providing a data processing unit. The controller of the invention is preferably an application specific integrated chip, a single chip, a server or a server cluster which can carry out data association, logic operation and control instruction sending. The invention can further maintain the stability of the dustproof quality by monitoring the working parameters of the nanofiber filter screen and timely replacing, thereby avoiding the reduction of the dustproof quality and reducing the replacement cost.
The electrical property monitoring unit obtains the electrical property parameter by applying a voltage to a portion of the nanofiber screen. And the data processing unit evaluates the dustproof quality evaluation based on the filtering state parameters of the corresponding nanofiber filter screen determined by the electrical property parameter variation curve. The voltage includes a direct current voltage and an alternating current voltage.
The invention prefers alternating voltage for collection and monitoring of electrical performance parameters. The types of electrical performance parameters that can be collected by the dc voltage are less than the types of electrical performance parameters that can be collected by the ac voltage. The data processing unit determines an oxidation level parameter and/or a cleanliness level parameter of the nanofiber screen associated with evaluating filtration capacity based on a change in a curve of at least one electrical property parameter and/or electromagnetic induction parameter associated with a skin effect with an alternating voltage applied to the nanofiber screen. The alternating current can also generate inductance and capacitance, and can generate a measurement mode of satisfied electrical performance parameters, so that the measurement of the electrical performance parameters is easier to match and adapt to the use environment, and errors and interference caused by matching are further reduced.
The skin effect in the invention is also called skin effect, when alternating current passes through a conductor, the current is concentrated on the surface of the conductor to flow. When electrons with higher frequency are conducted in the conductor, the current or voltage is collected on the surface layer of the total conductor, but not evenly distributed in the cross-sectional area of the whole conductor. Under the condition that alternating current flows at two ends of the nanofiber filter screen, the electrical property parameters related to skin effect and changes of the electrical property parameters can be monitored. The silver nanowires in the nanofiber filter screen are arranged into a hollow structure, and the conductivity of the silver nanowires is not influenced. Because the silver ion passivation occurs on the surface firstly, the oxidation degree of the silver can be judged more quickly and accurately by utilizing the skin effect, and the dustproof quality and the dustproof effect of the second closed net can be judged more quickly.
Compared with direct current voltage, the alternating current applied voltage has the advantages that the direct current is unidirectional, the anode and the cathode cannot be interchanged, and the electrical performance parameters are easy to cause inaccurate data due to large data errors in the test mode and the test direction. The alternating current at two ends of the alternating voltage is periodically changed along with time in magnitude and direction, and the alternating current has no positive and negative electrodes, so that the defect of inaccurate electrical property parameter measurement under the condition of unidirectional current is avoided. By adopting alternating voltage, the power supply can be set more easily in daily life, and electrical performance parameters measured under the condition of current change are accurate, so that the large data error caused by the interference of objective test conditions is not easy to generate.
By using alternating voltage, the silver nanowire has two selective structures of the silver nanowire with a hollow structure or the silver nanowire with a non-hollow structure, or a mixed structure of the silver nanowire with the hollow structure and the silver nanowire with the non-hollow structure, so that the cost is further saved. The silver nanowires with the hollow structures are beneficial to obtaining relevant electrical performance parameters of the nanofiber filter screen according to the skin effect principle under the condition that alternating current passes through, and are beneficial to saving of silver materials. The cavity of the silver nanowire with the hollow structure can be filled with conductive materials or non-conductive materials with other structures according to requirements. Compared with the silver nanowire with the hollow structure, the capacitance voltage of the hollow structure is more stable and is less interfered by impurities with oxidation degree by adopting alternating voltage for measurement. The alternating voltage range of the silver nanofiber filter screen is 2-20V, the voltage is low, personal safety accidents are not prone to occurring, electrical property parameters can be measured more easily, the correlation between the electrical property parameters and the silver oxidation degree or the cleanliness degree can be obtained more easily, and therefore the service life prediction and the dustproof quality evaluation of the nanofiber filter screen are more accurate.
As above, the structure of the closed cover can better prevent dust and remove dust, realize dust prevention and air environment purification of the mixing plant, and is beneficial to environmental protection and physical and psychological health of workers.
Preferably, at least one layer of coarse filter screen can be arranged in the first nanofiber filter screen and the second nanofiber filter screen and used for filtering coarse particle dust, so that the service life of the nanofiber filter screens is prolonged, and the dust prevention cost is relatively reduced. Preferably, the coarse filter screen and the nanofiber filter screen can be arranged in a fitting mode, and a spacing distance can exist, and the spacing distance is preferably 0.5 cm, 1 cm or more.
Preferably, the shape of first nanofiber filter screen and second nanofiber filter screen can be according to the nimble setting of the actual conditions of stirring building, as long as can realize that material transportation process's is sealed can. Preferably, a humidity sensor and a dehumidifier may be disposed in the environment where the first nanofiber filter and the second nanofiber filter are disposed. The humidity sensor and the starting switch of the dehumidifier are connected with the controller. When the humidity of environment reaches the humidity threshold that can accelerate the silver oxidation in the nanofiber filter screen, the controller starts the dehumidifier and dehumidifies, is favorable to prolonging the life of nanofiber filter screen. For example, a moisture sensor is disposed adjacent to the nanofiber web.
Preferably, in case of abnormal variation of the electrical performance parameter collected by the electrical performance monitoring unit, the controller adjusts the operating parameters of the at least one dehumidifier in such a way that the humidity parameter of the nanofibrous filter screen falls below a specified calibration threshold. The number of the dehumidifiers is not limited to one, and may be more.
The method of the present controller to evaluate the nanofiber screen is not limited to this manner of evaluating based on the electrical performance parameter. Preferably, the electrical property parameter monitoring unit at least further comprises a vibration acquisition component and an air supply component for monitoring the vibration parameters of the nanofiber filter screen. The nanofiber filter screen vibrates under the wind power of the air supply assembly. And under the condition that the air supply assembly is in a working state, the data processing unit evaluates the cleanliness parameter and/or the wind resistance parameter of the nanofiber filter screen based on the vibration parameter sent by the vibration acquisition assembly. The air supply assembly may be an air pump. For example, the air pump and the vibration collection assembly are integrally arranged and can be arranged on two sides of the nanofiber filter screen. Thereby collecting vibration parameters of the local nanofiber filter screen.
Preferably, the dustproof quality, the cleanliness parameter and/or the wind resistance parameter evaluated through the vibration parameters collected by the vibration collection assembly can also be used as reference data to evaluate whether the collected data of the electrical performance monitoring unit is accurate or not and judge whether the electrical performance monitoring unit breaks down or not.
If the variation trend of the wind resistance parameter and the variation trend of the cleanliness degree are opposite and the variation rates are similar, the dust accumulation degree on the nanofiber filter screen is consistent. The invention can form the cleaning degree parameter evaluated by the vibration parameter and the cleaning degree parameter determined by the electrical property parameter into mutual reference data, which is beneficial to finding out the sudden change abnormality of the data, thereby executing the calibration procedure of the data.
According to the invention, through the arrangement of the powder bins and the aggregate bins in the matrix array, the occupied space of the mixing plant is saved, and the manufacturing time of the material bins of the mixing plant is shortened; moreover, the invention also provides a dustproof system, so that the nanofiber filter screen can be replaced in time through a detection mechanism while the healthy working environment of workers is further realized, and the replacement cost of the dustproof filter screen is reduced under the condition of not reducing the working environment.
