Description

Automatic control system for separation of silicon slag

Technical field

The utility model relates to a silicon slag separation system, in particular to an automatic control system for separating silicon slag.

Background technique

Silicon slag generally refers to the remainder of the ore after refining, and also contains a certain amount of silicon. There are many kinds of silicon slag, industrial silicon slag, solar silicon slag, semiconductor silicon slag and so on. Silicon slag can be used to re-crystallize, purify, and now silicon is scarce, and the price is high. Silico-manganese slag, also called silico-manganese smelting slag, is an industrial waste slag emitted when smelting silicon-manganese alloy. Its structure is loose, and its appearance is often light green particles, which are composed of some irregular amorphous amorphous particles. Silicon-manganese slag, brittle and brittle, through the crusher can crush large pieces of silico-manganese slag into small pieces, and then into the fine crusher to further crush the coarsely crushed material to ensure that the material entering the silo can reach the monomer solution The degree of separation is then uniformly fed through the vibrating feeder and the belt conveyor, and the trapezoidal jig is sorted. The main purpose of the crushing is to break the structure of the continuous body. The main purpose of the jigging is to recover the silicon-manganese alloy from the silicon-manganese slag. There is a large difference in specific gravity between silicomanganese slag and silicomanganese alloy. The metal and waste slag can be separated by the re-selection of the jig to obtain pure alloy and waste slag. Finally, the concentrate and tail can be separated by dehydration of the dewatering sieve. The mine is dehydrated. Since the silicon-manganese slag contains a certain amount of silicon-manganese alloy, the recovery of the silicon-manganese alloy can be profitable, and at the same time reduce the occupation of the land and the environmental pollution of the silicon-manganese slag. The method of re-selecting silicon-manganese slag firstly recovers the silicon-manganese alloy from the waste silico-manganese slag, and then uses the waste slag as a building material, which can be used in the construction industry.

In the process of separating traditional silicon slag, natural separation is adopted. After a long period of time, the organic solution and the silicon slag are naturally separated, but this makes the separation time long, and the organic solution and silicon are fed during the feeding. The slag distribution is uneven, and the separation effect is not good. At the same time, in the feeding process, the organic solution and the silicon slag are generally added at one time. After the work is completed, the silicon slag and the organic solution are continuously added by manual manual; Later, some organic solutions will be lost, and the proportion of the remaining organic solution will also change. However, the artificial capacity is the overall capacity, which will only continue to increase, but it is impossible to discriminate the deviation of the substance content in the organic solution, resulting in the separation effect. difference. Therefore, we urgently need to study a system that automatically replenishes rehydration after processing, and adjusts the ratio and capacity of alcohol and tribromoethane in organic solvent in real time during operation to solve this problem and improve manual control. This problem.

The separation effect is poor, the speed of the separation process is increased, and the purpose is to provide an automatic control system for the separation of silicon slag, which solves the automatic replenishment replenishment after the completion of the processing, and adjusts the alcohol and tribromide in the organic solvent in real time during the operation. The ratio and capacity of ethane, while avoiding the uneven distribution of organic solution and silicon slag, make the separation effect poor, and increase the speed of the separation process. The problem of less time.

The utility model is realized by the following technical solutions:

The silicon slag is transported to the stirring chamber; the timer is timed by the feed controller, and the feed controller is based on the received silicon slag time value information sent by the upper computer. The timing controller: receiving an operation time instruction sent by the upper computer, and sending a stirring instruction to the nozzle agitator by timing of the timer; the nozzle agitator: receiving the stirring instruction sent by the timing controller, stirring the stirring chamber; The infrared detector detects the layer information in the stirring chamber, sends it to the upper computer in real time, receives the layer information and processes the upper computer, and sends a rotation command to the rotating stirring module; the rotating stirring module: receives the rotation instruction of the upper computer The residue filter rotates; the residue filter receives the slag command sent by the upper computer to collect the slag from the stirring chamber; and the single-type silicon filter receives the silicon receiving command sent by the upper computer to receive the silicon in the stirring chamber. The silicon slag filter receives the silicon receiving command sent by the upper computer to collect the silicon slag from the stirring chamber. In the process of separating the traditional silicon slag, in the feeding process, the organic solution and the silicon slag are generally added at one time, and after the work is completed, the silicon slag and the organic solution are continuously added by manual manual; after the processing is completed, There will be some organic solution loss, the remaining organic solution ratio The case has also changed, but the overall judgment is the overall capacity, which will only continue to increase, but it is impossible to discriminate the deviation of the substance content in the organic solution, resulting in poor separation effect. Therefore, the utility model solves this problem by developing a system for automatically replenishing liquid replenishment after processing, and adjusting the ratio and capacity of alcohol and tribromoethane in an organic solvent in real time during operation, in the feed portion, Receiving the weight information of the silicon slag sent by the host computer, collecting the weight of the weighing tank module in real time through the belt scale module and comparing the weight value and time value information of the silicon slag sent by the upper computer, and stopping the feeding when the set target is reached, the difference is The traditional technology lies in that the first mechanical weighing feed does not require manual manual feeding, which reduces the output of the worker's physical strength; the second adopts a circulation device, which is also more self-energy, reduces manual manual control, and saves labor costs. A greater breakthrough in the liquid inlet section, as well as the feeding process, is completely intelligent, and there is also a concentration ratio test. The organic solution is composed of alcohol and tribromoethane, but in the process of separating the silicon slag. The consumption ratio of alcohol and tribromoethane is not exactly the same. The utility model increases the detecting device, and adjusts by the PID controller, more fully utilizes the organic solution to separate the silicon slag, improves the separation rate, and is very beneficial. The effect is that in the process of separation, natural separation is used. After a long period of time, the organic solution and the silicon residue are naturally separated, but this makes the separation time long, and the organic solution and silicon are fed during the feeding. The slag distribution is uneven and the separation effect is not good. In order to solve this problem, the utility model adopts the method of increasing the stirring, the stirring can speed up the separation speed, and the problem of uneven distribution of the organic solution and the silicon slag during the feeding can be improved, from two problems. To achieve this goal, the first step is to set up the timing controller, which can be set according to the time characteristic of each silicon slag. The working period of the controller is to work for 10 seconds each time to enter the silicon slag, and issue a working command to the nozzle agitator. The nozzle agitator stirs the stirring chamber to evenly distribute the organic solution and the silicon slag, thereby improving the separation effect. On this basis, the infrared detector is further added to detect the liquid information in the stirring chamber. This is a double guarantee. The first layer of stirring is controlled by time and automatically stops after 10 seconds, but it is still possible. Stirring is uneven, so the infrared detector detection information is increased, converted into grayscale image in the upper computer, judged according to the built-in grayscale ratio, and the instruction is given to the rotary stirring module to improve the organic solution by rotating the bottom of the stirring chamber. The distribution of silicon slag. The utility model solves the problem that the uneven distribution of the organic solution and the silicon slag is avoided, the separation effect is poor, and the speed of the separation process is reduced, and the time setting of the timing controller can be freely set, and the utility model only 10 seconds as an example.

The weight ratio of alcohol to tribromoethane in the organic solution was 17:1. Based on the density values of elemental silicon, alcohol and tribromoethane, the optimum ratio, 17:1, is obtained, which optimizes the separation distance and effect.

An automatic control system for separating silicon slag further includes an alarm device, and the upper computer sends an alarm message to the alarm device, and the alarm device receives the alarm information of the upper computer and emits a whistle alarm sound, in order to avoid failure due to failure of other components. Excessive liquid, or the liquid overflows when stirring, set a safety function, the liquid level sensor and the information on the host computer, exceed the limit value, send a message to the alarm, and the alarm sounds an alarm.

The upper computer also sends a slag discharge command, a silicon receiving command or a silicon slag command to the recycling center; the recycling center includes a silicon slag filter, a single silicon filter and a residue filter. The residue filter receives the slag command sent by the host computer to stir The slag is collected by the cavity; the single-crystal silicon filter receives the silicon receiving command sent by the upper computer to receive silicon from the stirring chamber. The silicon slag filter receives the silicon receiving command sent by the upper computer to collect the silicon slag from the stirring chamber. The traditional recycling system is unified after the work is completed, all materials are removed through the filter, but there is a very big problem in this process. During the separation process of silicon slag, the separated substances are not only good for elemental silicon and residue, but also There is a part of the small particle silicon slag that has not been separated. If it is directly excluded, it is very wasteful. If it is excluded after the second addition, it will take time and effort; the system can be set to remove the elemental silicon and residue after the end of the upper machine, for the remaining The silicon slag can be processed in the upper computer according to the information detected by the infrared detector to form a gray scale image, which is manually controlled by the staff to be cleared. This avoids the deficiencies of the traditional approach.
