[0018] In order to better understand the technical scheme of the utility model, the following will be described in detail through specific examples:
[0019] Please refer to Figure 1 and Figure 2 The simple cutting fluid recycling device of the utility model comprises a water pump 4 and a filtering and sewage discharging device.
[0020] Specifically, the filtering and sewage discharging device comprises a collecting barrel 1, an oil discharge barrel 2 and a sewage discharge barrel 3. The collecting barrel 1, the oil discharge barrel 2 and the sewage discharge barrel 3 are barrel-shaped structures with equal diameters and are arranged in a stacking manner from top to bottom, and are isolated by a filter element between the collecting barrel 1 and the oil discharge barrel 2.
[0021] Each barrel is a stainless steel barrel, and the combination part is firmly welded to ensure no water leakage.
[0022] As a preferred, a waterproof belt is covered on the connecting part of each barrel as a waterproof seal.
[0023] The top of the collecting barrel 1 is provided with a waste liquid inlet connected with the water pump 4. The water pump 4 is connected with the waste liquid tank to pump the cutting fluid to be recycled into the collecting barrel 1. The waste liquid in the collecting barrel 1 is filtered by the filter element and then collected in the oil discharge barrel. The oil discharge barrel 2 is provided with an oil discharge port 21, and the oil discharge barrel 3 is provided with a sewage discharge port 31. Valves are arranged on the oil discharge port and the sewage discharge port respectively.
[0024] Preferably, the diameter-height ratio of the collecting barrel, the oil discharge barrel and the sewage discharge barrel is 1:1.5. A liquid level meter is arranged on one side of the oil discharge barrel 2. When the cutting fluid is recycled by using the device, only the middle layer of the recycled liquid is recycled, and therefore the liquid level meter is used to help the operator to know the liquid level in the device in real time.
[0025] Preferably, the oil discharge port and the sewage discharge port are arranged at the position of 1 / 3 of the height of the oil discharge barrel and the sewage discharge barrel respectively. This position is also used to ensure that the middle layer of the cutting fluid can be recycled.
[0026] In the embodiment, the specific installation mode of the filter element is as follows.
[0027] The abutting portion of the collecting barrel 1 and the oil discharge barrel 2 is provided with an inward flange structure. The flange structure is provided with a connecting hole. The outer ring of the filter element is provided with a pad layer. The pad layer is provided with a fixing hole matched with the connecting hole. The filter element is fixed to the upper surface of the flange structure by a fastener. The pad layer of the outer ring of the filter element is provided with a lifting ring for replacing the filter element.
[0028] Preferably, the material of the filter element is non-woven fabric. The pore size of the filter element is 50 mesh.
[0029] The specific process of recycling the cutting fluid by using the device is as follows.
[0030] Firstly, the waste liquid is pumped from the waste liquid tank into the collecting barrel by the water pump. The waste liquid in the collecting barrel is filtered by the filter element and then collected in the sewage discharge barrel. With the continuous working of the water pump, the liquid level in the device gradually rises. When the liquid level approaches the filter element, the water pump is stopped to prevent the liquid level from being higher than the filter element and to hinder the filtration of the filter element. The main function of the filter element is to filter out the solid impurities and debris with large volume in the waste liquid.
[0031] After the waste liquid is collected, the waste liquid is allowed to stand and deposit in the device. The process lasts for 24 hours. In this process, the waste liquid is gradually and naturally stratified into an upper oil floating layer, a middle recycled liquid layer and a bottom sludge layer. The bottom sludge layer is collected in the sewage discharge barrel.
[0032] After the standing and depositing are completed, the oil discharge port valve is opened to recycle the middle recycled liquid layer. The operator needs to pay attention to the liquid level in the device at all times. When the liquid level approaches the preset height, the oil discharge port valve is closed to avoid recycling the oil floating layer.
[0033] When it is necessary to clean, open the bottom drain valve, and then all the waste liquid including the bottom sludge can be discharged.
[0034] When it is necessary to replace the filter core, the fastener of the filter core is removed from the top of the collecting barrel, and then the filter core is lifted out through the tool clamp, so that the filter core replacement is completed. After the filter core is lifted out, the bottom of the device can be cleaned through the high-pressure water gun.
[0035] Those skilled in the art of the present technology should recognize that the above embodiments are only used to illustrate the present utility model, and are not used as a limitation on the present utility model. As long as the changes and modifications of the above described embodiments are within the scope of the spirit of the present utility model, they will fall within the scope of the claims of the present utility model.
