Description

[Technical field]

[0001] The invention relates to the technical field of aluminum shell cleaning, in particular to a system and method for recycling aluminum shell cleaning wastewater. [Background Technology]

[0002] At present, the aluminum shell cleaning in the industry is to discharge the cleaning wastewater directly into the sewage treatment pool, and then discharge it after treatment. The main shortcomings are as follows: the sewage treatment cost is high, and the cleaning machine consumes a lot of water and is complicated to operate, which makes the subsequent factory's mass production burden heavy, thus affecting production efficiency.

[0003] Therefore, if a reuse treatment system can be provided, the lightly contaminated water generated can be used directly without treatment, thereby reducing the cost of sewage treatment and the water consumption of the cleaning machine. The operation is simple and convenient to add water to the cleaning machine, and it can also save the time for heating the cleaning water. Ultimately, it will reduce the water treatment burden for subsequent large-scale production in factories and increase production efficiency, which will be of great significance. [Summary of the invention]

[0027] Among them, a pumping motor 2-1 is installed on the pipeline between the sewage collection tank 9 and the quartz sand filter barrel 3, and the slightly polluted water in the sewage collection tank 9 is flowed to the quartz sand filter barrel 3 through the pumping motor 2-1, and the quartz sand filter barrel 3 is used to first filter out the coarse solid impurities remaining in the water; a pumping motor 2-2 is installed on the pipeline between the quartz sand filter barrel 3 and the activated carbon filter barrel 4, and the slightly polluted water filtered by the quartz sand filter barrel 3 is flowed to the activated carbon filter barrel 4 through the pumping motor 2-2, and the activated carbon filter barrel 4 is used to filter out the fine impurities in the water; a pumping motor 3 2-3 is provided on the pipeline between the activated carbon filter barrel 4 and the filter water barrel 10, and the pumping motor 3 2-3 collects the water treated by the quartz sand filter barrel 3 and the activated carbon filter barrel 4 into the filter water barrel 10; a pumping motor 4 2-4 is installed on the pipeline between the filter water barrel 1 and the heating water tank 5, and the water in the filter water barrel 10 is flowed to the heating water tank 5 through the pumping motor 4 2-4.

[0028] The present invention also provides a method for recycling aluminum shell cleaning wastewater, comprising the following steps:

[0029] 1) First, collect the slightly polluted water discharged from the pure water tank 1 of the cleaning machine into the sewage collection tank 9;

[0030] 2) When the sewage in the sewage collection tank 9 accumulates to a certain height, the water is processed by the pumping motor through the quartz sand filter barrel 3 and the activated carbon filter barrel 4 in sequence so that the water does not contain solid impurities, and then the treated water is collected in the filter water barrel 10;

[0031] 3) The lightly polluted water in the filtered water bucket 10 is heated by the heating water tank 5 and then enters the cleaning tank 7 of the cleaning machine; after the lightly polluted water in the heating water tank 5 is heated, it can also be firstly passed through the filter element device 6 for another filter element cycle before entering the cleaning tank 7 of the cleaning machine to ensure that there is no scale in the water storage and heating process;

[0032] 4) The pH concentration of the water in the cleaning tank 7 of the cleaning machine is monitored in real time by the pH value online detector 8, and cleaning agent is added according to the pH value concentration to achieve the desired pH value, and then cleaning can be carried out.

[0033] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments:

[0034] A system that can be used directly after a little treatment of the waste, with Figure 1 This is a flow chart for the system to achieve the reuse of slightly polluted water. The system mainly consists of a cleaning machine pure water tank 1, a pumping motor, a quartz sand filter barrel 3, an activated carbon filter barrel 4, a heating water tank 5, a filter element equipment 6, a cleaning machine cleaning tank 7, a PH value online detector 8, a sewage collection tank 9, a filter water bucket 10, etc.

[0035] First, during the production process, pure water continuously flows into the pure water tank 1 of the cleaning machine to ensure that the tank is in a "live water" state, so that the rinsed products can be clean, but there is also a continuous flow of slightly polluted water discharged from the overflow port; the discharged slightly polluted water will flow to the sewage collection tank 9 for collection; it will flow to the quartz sand filter barrel 3 through the pumping motor 1 to first filter out the coarse solid impurities remaining in the water; then it will flow to the activated carbon filter barrel 4 through the pumping motor 2 to filter out the fine impurities again; the treated water will be collected into the filter water barrel 10 through the pumping motor 3; the water in the filter water barrel 10 will flow into the heating water tank 5 through the pumping motor 4; the hot water in the heating water tank 5 will pass through the filter element device 6 through the pumping motor 5 and enter the cleaning tank 7 of the cleaning machine. Since the filtered water is slightly polluted water containing cleaning agent and has a certain pH value, it is necessary to monitor it in real time with the pH value online detector 8, and then add the agent according to the pH value concentration in the water until the cleaning water reaches the required pH concentration.

[0036] The present invention can be divided into 4 main steps:

[0037] Step 1: Collect the lightly polluted water discharged from the cleaning machine into the sewage pool;

[0038] Step 2: When the sewage in the sewage pool accumulates to a certain height, the treatment can begin; specifically, the water is treated twice by a pumping motor (first quartz sand, then activated carbon) to ensure that the water does not contain solid impurities, and then the treated water is collected in a large bucket;

[0039] Step 3: Heat the treated lightly polluted water to save production time. Because the current cleaning machines are all heated by cold water, the efficiency is low and the time is long, which seriously affects the production capacity. Heating the water in advance and introducing it into the cleaning tank of the cleaning machine can greatly improve the production efficiency. Before adding it, the filter element will be circulated again. This cycle is to ensure that there is no scale (mainly white solid particles precipitated by calcium ions) brought into the water during the storage and heating process.

[0040] Step 4: Add cleaning agent according to its pH concentration to reach the desired pH value and then start cleaning.

[0041] This process also directly optimizes the water changing and heating process of the cleaning machine.
