[0039] As described in the background art: The circular grinding machine is one of the common processing equipment for silicon carbide crystals. A waste oil collector is usually provided on the circular grinding machine to collect the oil mixture (hereinafter simply referred to as waste oil) left during processing. However, the existing waste oil collectors generally have the problem that the waste oil is prone to solidification, which affects the normal collection of waste oil. The designer of the present utility model found in the research that the reason for the problem that the waste oil is prone to solidification and affects the normal collection of waste oil is that the bottom of the collection box of the waste oil collector is horizontally arranged, and the drain valve is arranged on one side wall of the collection box. On the one hand, the waste oil is not easily drained completely, and on the other hand, the accumulated waste oil is not easily discharged, resulting in the waste oil being prone to solidification. To solve the above technical problems, the embodiments of the present utility model provide a waste oil collector and a circular grinding machine for processing silicon carbide crystals, which can prevent the waste oil from solidifying easily, make it easier to discharge the waste oil, and ensure the normal collection of waste oil.
[0040] Please refer toFigure 1 , an embodiment of the present utility model provides an waste oil collector 10, which is applied to a rotary grinder for processing silicon carbide crystals. The rotary grinder includes a grinder body and the above-mentioned waste oil collector 10, wherein the grinder body is connected to the waste oil collector 10 to introduce the generated waste oil into the waste oil collector 10. Among them, the waste oil is an oil-liquid mixture generated during the processing of silicon carbide crystals by the grinder body, usually a mixture of oil and water.
[0041] The waste oil collector 10 includes a collection box body 100 and a drain valve 200. Among them, the collection box body 100 includes a box shell 110 and a diversion bottom shell 120. The box shell 110 is cylindrical, and the top peripheral edge of the diversion bottom shell 120 is connected to the bottom of the box shell 110 and jointly encloses a storage cavity 130 for storing waste oil with the box shell 110. A drain port 121 is provided at the lowest point of the bottom of the diversion bottom shell 120, and the diversion bottom shell 120 is inclined from its top side to the bottom to guide the waste oil to the drain port 121. The drain valve 200 is provided at the drain port 121 for opening or closing the drain port 121.
[0042] When the waste oil collector 10 is working, the waste oil generated by the grinder body of the rotary grinder flows into the collection box body 100, and the storage cavity 130 stores the waste oil. When it is necessary to discharge the waste oil, only need to open the drain valve 200 to open the drain port 121, and the waste oil will be discharged through the drain port 121 under the action of gravity. Since the drain port 121 is provided at the lowest point of the bottom of the diversion bottom shell 120, and the diversion bottom shell 120 is inclined from its top side to the bottom, the diversion bottom shell 120 has a guiding effect on the waste oil, which can guide the waste oil to the drain port 121, so that the waste oil is not easy to solidify, and the drain valve 200 will not be blocked due to the solidification of the waste oil, which is more convenient for the waste oil to be discharged and ensures the normal collection of the waste oil.
[0043] In some alternative embodiments, the drain port 121 is located at the center of the bottom of the diversion bottom shell 120. In this way, the waste oil in the storage cavity 130 can flow to the center of the bottom of the diversion bottom shell 120 under the action of gravity, which is convenient for the waste oil to be discharged from the drain port 121. In addition, for the waste oil at each part of the diversion bottom shell 120, the travel of the waste oil flowing to the drain port 121 will also be shorter, further reducing the possibility of waste oil solidification and not easily forming waste oil solidification, which is convenient for the waste oil to be discharged.
[0044] In some alternative embodiments, the longitudinal section of the diversion bottom shell 120 is in the shape of an inward concave arc.
[0045] That is to say, the diversion bottom shell 120 is an arc-shaped shell structure with a downward concave bottom as a whole, and the liquid discharge port 121 is located at the center of the bottom of the entire arc-shaped shell structure. In this way, due to the concave arc surface, it can play a better guiding role for the waste oil, enabling the waste oil to effectively flow to the liquid discharge port 121 under the action of gravity and not easily solidify, further ensuring the smooth discharge of the waste oil.
[0046] In addition, in some alternative embodiments, the diversion bottom shell 120 is in an inverted conical shape.
[0047] That is to say, the diversion bottom shell 120 can also be an inverted conical shell structure. In this way, the diversion shell forms an inverted conical structure with a high surrounding and a low middle part, and the diversion bottom shell 120 is an inclined plate, which can also play a guiding role for the waste oil, prevent the waste oil from solidifying, and ensure the normal discharge of the waste oil.
[0048] In some alternative embodiments, a tray 300 is arranged below the liquid discharge port 121 for receiving the waste oil flowing down from the liquid discharge port 121.
[0049] By arranging the tray 300, the waste oil flowing down from the liquid discharge port 121 can be received, and the discharged waste oil can be effectively collected.
[0050] Please refer to Figure 1 and Figure 2 , in some alternative embodiments, the waste oil collector 10 may further include an oil sensor 400 and a controller 500. Among them, the oil sensor 400 is arranged at the liquid discharge port 121 and is used to generate a water discharge completed signal when detecting oil. The controller 500 is electrically connected to both the oil sensor 400 and the drain valve 200, and is used to control the drain valve 200 to close when receiving the water discharge completed signal, so as to replace the tray 300.
[0051] It should be noted that in some embodiments, since the waste oil is a mixture of oil and water, the waste oil can be separated into oil and liquid and then discharged. Also, because the density of oil is smaller than that of water, after the waste oil is placed in the accommodation space, the oil will float on the water surface. Therefore, after the drain valve 200 is opened, the water at the bottom will be discharged first, and then the oil on the water surface will be discharged. By arranging the oil sensor 400, during the process of discharging the waste oil, the water at the bottom is discharged first until the oil sensor 400 detects oil. At this time, the oil sensor 400 generates a water discharge completed signal, which means that all the water at the bottom has been discharged at this time and the oil discharge starts. At this time, when the controller 500 receives the water discharge completed signal, it controls the drain valve 200 to close so as to replace the tray 300, remove the tray 300 that has received water at this time, and replace it with an empty tray 300 to receive the remaining oil, thus realizing the separation of oil and liquid.
[0052] In some alternative embodiments, the drain valve 200 is an electronic faucet.
[0053] By setting the drain valve 200 as an electronic faucet, the electronic faucet can be electrically connected to the controller 500 so that the controller 500 can control the electronic faucet.
[0054] In some alternative embodiments, the housing 110 is cylindrical, and the top side of the diversion bottom shell 120 is circular and matches the shape of the bottom of the housing 110.
[0055] In this way, both the housing 110 and the diversion bottom shell 120 have a circular cross-section, and the diversion bottom shell 120 forms a circle, facilitating the confluence of waste oil to the drain port 121 at the center of the bottom.
[0056] In some alternative embodiments, the housing 110 and the diversion bottom shell 120 are integrally formed. In this way, the housing 110 and the diversion bottom shell 120 are easy to form. In other embodiments, the housing 110 and the diversion bottom shell 120 can also be detachably connected.
[0057] In summary, when the waste oil collector 10 provided by the embodiment of the present invention and the rotary grinding machine for silicon carbide crystal processing are working, the waste oil generated by the rotary grinding machine flows into the collection box 100, and the accommodation cavity 130 accommodates the waste oil. When it is necessary to discharge the waste oil, only need to open the drain valve 200 to open the drain port 121, and under the action of gravity, the waste oil is discharged through the drain port 121. Since the drain port 121 is provided at the lowest position of the bottom of the diversion bottom shell 120, and the diversion bottom shell 120 is inclined from its top side to the bottom, the diversion bottom shell 120 has a guiding effect on the waste oil and can guide the waste oil to the drain port 121. In this way, the waste oil is not likely to solidify, and the drain valve 200 will not be blocked due to the solidification of the waste oil, which is more convenient for the discharge of the waste oil and ensures the normal collection of the waste oil.
[0058] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
