Description

Technical Field

[0001] The utility model relates to the technical field of glass processing, in particular to an automatic treatment system for waste water from glass edge grinding. Background Art

[0002] In the glass edge grinding process, a large amount of glass powder is discharged with the cooling water to form wastewater. The common treatment method is to precipitate through the sedimentation tank and clean the sediment regularly. However, due to the need to stop the machine for cleaning and the large amount of cleaning, the downtime required for each cleaning is long, which affects the glass edge grinding process. The cleaning process consumes a lot of manpower and has high labor intensity. The salvaged sediment needs to be dried in the sun for a long time before being treated as solid waste. The treatment cycle is long and occupies a large area. Summary of the invention

[0011] Attached Figure 1 This is a schematic diagram of the overall structure of an embodiment of the utility model;

[0012] Attached Figure 2 The figure is a schematic structural diagram of a separation module according to an embodiment of the utility model. DETAILED DESCRIPTION

[0013] The utility model is further described below in conjunction with the accompanying drawings.

[0014] As attached Figure 1-2 The automatic treatment system for glass edge grinding wastewater comprises a wastewater pool 1, wherein the wastewater pool 1 is connected to a solid-liquid separation mechanism 3 through a suction pipeline 2, the solid output end of the solid-liquid separation mechanism 3 is connected to a filter press mechanism 4, the liquid output end of the solid-liquid separation mechanism 3 is connected to a clean water pool 5, and the clean water pool 5 is connected to a cooling water circulation pipeline 6 through a water pump.

[0015] This solution collects and temporarily stores wastewater in a wastewater pool, and actively draws wastewater into a solid-liquid separation mechanism through a suction pipeline, so that the wastewater is divided into two parts: sludge and sewage. The sludge part is drawn into a filter press by a diaphragm pump for further solid-liquid separation to obtain glass powder cakes with extremely low water content, which are transported to a packaging point by a conveyor belt for centralized solid waste treatment. There is no need to occupy a large area for drying or air drying. The sewage obtained after the two separations is drained into a clear water pool, and is treated with chemicals to form relatively clear water, which is used to supply cooling water for recycling.

[0016] Preferably, an aeration device 7 is provided at the bottom of the wastewater pool 1, and the water inlet of the wastewater pool is located above the aeration device. The wastewater can be disturbed by aeration for a long time, thereby avoiding the premature precipitation of the glass powder. Firstly, it can effectively avoid the blockage of the suction pipeline caused by precipitation during extraction, and secondly, it can ensure the uniform distribution of the solid content, which is conducive to controlling the dosage during solid-liquid separation.

[0017] The solid-liquid separation mechanism 3 is provided with a plurality of separation modules, and the separation modules include a treatment tank 31 erected above the wastewater pool 1, the top of the treatment tank 31 is provided with an access port 32 connected to the suction pipeline 2, and a dosing port 33 connected to the drug dispensing tank, the bottom end of the treatment tank 31 is connected to the filter press mechanism 4 through a diaphragm pump 34, and the upper tank wall of the treatment tank 31 is provided with an overflow port 35, and the overflow port 35 is connected to the clean water pool 5 through a pipeline.

[0018] Multiple separation modules work simultaneously to improve the processing capacity, and each module operates independently, so the blockage and shutdown of individual modules have little impact on the overall processing capacity. The opening and closing of the dosing port is synchronized with the opening and closing of the corresponding access port. Under the premise of ensuring sufficient supply of drugs, when a certain volume of wastewater is pumped in, the corresponding volume of drugs is added, thereby maintaining the best solid-liquid separation effect.

[0019] The inner wall of the treatment tank 31 is provided with a solid deposition amount detection module 8, and the signal output end of the solid deposition amount detection module 8 is electrically connected to the corresponding diaphragm pump 34 through the control module. The solid deposition amount detection module 8 can adopt a sludge concentration sensor or directly adopt a visual module, which can reflect the amount of solid deposition in the tank. When extracting sludge to the filter press, the sludge content fed back from each tank is compared, and the sludge in several tanks with larger sludge deposition amount is selected to maintain the balance of sludge in multiple tanks to avoid blockage of the overflow port due to excessive deposition.

[0020] The overflow port 35 is provided with an overflow valve and a concentration detection module 9, and the signal output end of the concentration detection module 9 is electrically connected to the corresponding overflow valve through the control module. By detecting the change of sewage concentration at the overflow port, it is ensured that the sewage concentration discharged to the clean water tank is within the allowable range, and it is ensured that it can be used as cooling water circulation after the dosing treatment. If the sewage concentration detection value is high, the overflow valve is closed for a period of time, and a better solid-liquid separation effect is obtained by prolonging the drug action time and sedimentation time.

[0021] The processing tank 31 is internally provided with a liquid level sensing module 10 , the suction pipeline 2 is provided with a waste liquid suction pump 21 , and the signal output end of the liquid level sensing module 10 is electrically connected to the corresponding waste liquid suction pump 21 through a control module.

[0022] When the sludge in the tank is extracted or the sewage overflows, the liquid level in the tank will decrease, thereby freeing up a certain amount of processing capacity. At this time, by sensing that the liquid level is lower than a certain threshold, the corresponding suction pipeline is triggered to start working, thereby ensuring the continuity of wastewater treatment.

[0023] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
