Description

Technical Field

[0001] The utility model relates to an oil-water separation device for a numerically controlled gantry machine tool, and mainly relates to the field of oil-water separation. Background Art

[0002] During the process of machining workpieces by a numerically controlled gantry machine tool, oil-water mixed spraying is usually used for cooling and lubrication. A collecting device needs to be set under the machine tool to collect it, and then the oil and water are separated. At present, related separation devices, such as the patent document with the publication number of CN106217124A, disclose an oil-water separation treatment device for a machining center, which adopts an overflow type to separate oil and water. Based on the better characteristic of the oil density, the oil on the upper layer overflows and is separated. There are some problems when using this scheme. Because of the oil impurities in the oil-water mixture, the water outflow speed is not constant, or the flow rate of the sprayed water is not constant, resulting in sometimes more and sometimes less oil and water in the collecting bin. If there is too much oil and water in a short time, it is easy to cause the water level to rise and the water in the lower layer to overflow together. If the oil and water are too little, the oil on the upper layer will be discharged from the drain port. Content of the Utility Model

[0003] Aiming at the above deficiencies of the prior art, the utility model provides an oil-water separation device for a numerically controlled gantry machine tool, which can adjust the drainage flow rate according to the liquid level height, and can avoid water from entering the oil tank or oil from being discharged from the drain port.

[0004] To achieve the above object, the technical solution of the utility model is: it includes a separation tank and a water receiving tank, and the water receiving tanks are respectively arranged on the left and right of the upper part of the separation tank;

[0005] It is characterized in that the separation tank includes a mixing chamber and an oil tank. The mixing chamber is communicated with the water receiving tank. An overflow port communicated with the oil tank is arranged on the upper part of the mixing chamber. A drain port is arranged on the lower part of the mixing chamber. A valve is arranged at the drain port. A floating block is arranged on the liquid level of the mixing chamber. The floating block is linked with the valve. The higher the floating height of the floating block, the larger the opening diameter of the valve.

[0006] The technical principle and beneficial effects of the utility model are as follows:

[0007] The drain outlet is located at the lower part of the mixing chamber, and the overflow outlet is located at the upper part of the mixing chamber. Since the oil has a lower density and floats on the upper layer, this property can be well utilized to discharge the oil on the upper layer from the overflow outlet into the oil storage tank, while the water on the lower layer is discharged from the drain outlet. In this solution, the valve is linked with a floating block arranged on the liquid level. When there is more mixed liquid in the mixing chamber, the liquid level rises, the opening diameter of the valve becomes larger, and the internal liquid can discharge the water on the lower layer faster, preventing the water on the lower layer from flowing out of the overflow outlet. When the liquid level drops, the diameter of the valve becomes smaller, and the water on the lower layer will flow out slowly or even close the valve, and the liquid level rises so that the oil layer can continue to overflow upward into the oil storage tank.

[0008] Through the above solution, the liquid level height of the mixing chamber can be automatically adjusted, preventing the oil from flowing out of the drain outlet or the water from flowing out of the overflow outlet, making the oil-water separation more convenient and efficient.

[0009] Preferably, the valve includes an outer cylinder and an inner cylinder. The outer cylinder is vertically arranged relative to the mixing chamber. The lower end of the outer cylinder is the liquid outlet, and the drain outlet is arranged corresponding to the lower part of the mixing chamber on the outer cylinder. The inner cylinder is sleeved inside the outer cylinder and is slidably matched with the outer cylinder. The inner cylinder is relatively fixed to the floating block. During the up and down movement of the inner cylinder, the lower edge of the inner cylinder will block or open the drain outlet. Using the outer cylinder and inner cylinder to realize the linkage between the valve and the floating block, the overall performance is more stable, and the linkage between the two is better realized. When the liquid level rises, the inner cylinder will also rise, preventing the oil on the liquid level from entering the inside through the upper port of the outer cylinder.

[0010] Preferably, the upper end of the inner cylinder is open. To ensure the balance of internal and external air pressures and prevent the inner cylinder from sliding downward together when water enters the outer cylinder.

[0011] Preferably, the inner cylinder is connected to the floating block through a connecting rod. To more flexibly set the relative positions of the two.

[0012] Preferably, the drain outlet is a number of holes evenly distributed. It can play a certain filtering role, and the distribution of several holes can better control the flow rate.

[0013] Preferably, the drain outlets are distributed around the periphery of the outer cylinder. To facilitate the water to flow out better.

[0014] Preferably, a filter cover is arranged inside the drain outlet. To prevent blockage caused by impurities.

[0015] Preferably, the oil storage tank is a cylindrical structure arranged inside the mixing chamber. The lower end of the cylindrical structure is communicated with the outside, and the upper end of the cylindrical structure is open. It is more convenient to set the overflow outlet.

[0016] Preferably, a plurality of filter holes are distributed on the upper side wall of the cylindrical structure to filter impurities on the liquid surface. BRIEF DESCRIPTION OF THE DRAWINGS

The water receiving tanks are respectively arranged on the left and right of the upper part of the separation tank. It is characterized in that the separation tank includes a mixing bin 1 and an oil bin 9. The mixing bin is communicated with the water receiving tank. An overflow port communicated with the oil bin 9 is arranged on the upper part of the mixing bin 1. A drain port 7 is arranged on the lower part of the mixing bin 1. A valve is arranged at the drain port 7. A floating block 5 is arranged on the liquid surface of the mixing bin 1. The floating block 5 is linked with the valve. The higher the floating height of the floating block 5, the larger the opening diameter of the valve.

[0023] The drain port 7 is located at the lower part of the mixing chamber 1, and the overflow port is located at the upper part of the mixing chamber 1. Since the oil has a lower density and floats on the upper layer, this property can be well utilized to drain the oil in the upper layer from the overflow port into the oil storage 9, while the water in the lower layer is drained from the drain port 7. In this solution, the valve is linked with the floating block 5 arranged on the liquid level. When there is more mixed liquid in the mixing chamber 1, the liquid level rises, the opening diameter of the valve becomes larger, and the internal liquid can drain the water in the lower layer faster, preventing the water in the lower layer from flowing out through the overflow port. When the liquid level drops, the diameter of the valve becomes smaller, and the water in the lower layer will flow out slowly or even close the valve, and when the liquid level rises, so that the oil layer can continue to overflow upward into the oil storage 9.

[0024] Through the above solution, the liquid level height of the mixing chamber 1 can be automatically adjusted, preventing the oil from flowing out through the drain port 7 or the water from flowing out through the overflow port, making the oil-water separation more convenient and efficient.

Using the outer cylinder 6 and the inner cylinder 3 to realize the linkage between the valve and the floating block 5, the overall performance is more stable, and the linkage between the two is better realized. When the liquid level rises, the inner cylinder 3 will also rise, preventing the oil on the liquid surface from entering the interior through the upper port of the outer cylinder 6.

[0026] The upper end of the inner cylinder 3 is open. To ensure the balance of internal and external air pressures and prevent the inner cylinder 3 from sliding downward together when water enters the outer cylinder 6.

[0027] The inner cylinder 3 is connected to the floating block 5 through a connecting rod. So as to set the relative positions of the two more flexibly.

[0028] The drain port 7 is a number of holes evenly distributed. It can play a certain filtering role, and the distribution of a number of holes can better control the flow rate.

[0029] The drain port 7 is distributed around the outer periphery of the outer cylinder 6. So that the water can flow out better.

[0030] A filter cover 8 is arranged inside the drain port 7. To prevent blockage caused by impurities.

[0031] The oil storage 9 is a cylindrical structure arranged inside the mixing chamber 1. The lower end of the cylindrical structure is communicated with the outside, and the upper end of the cylindrical structure is open. It is more convenient to set the overflow port.
