Structure of telescopic water-absorbing float

Abstract

A retractable water-absorbing float structure mainly comprises a base body, a telescopic rod, and a float structure. Its characteristic is that when the water-absorbing float structure is placed in a cutting fluid tank containing a mixture of waste oil and iron filings (used cutting fluid), and a cleaner cutting fluid is to be extracted for reuse, simply placing the water-absorbing float structure in the cutting fluid tank will cause the float structure to continuously float on the liquid surface. Its upper and lower through-holes will be positioned below the waste oil and outside the cutting fluid surface. The telescopic rod and base body below the float structure will automatically extend, causing the base body to automatically sink to the bottom of the cutting fluid tank. When the pump is activated, the lower central through-hole of the float structure automatically draws in only relatively clean cutting fluid, which flows through the telescopic rod and the base body into the hose fitted on the L-shaped pipe and into the recovery tank. The baffle cup on the float structure also automatically prevents iron filings floating on the surface of the cutting fluid tank from entering the lower through-hole. The height of the float structure also automatically changes with the height of the cutting fluid level to keep the float structure above the cutting fluid level at all times. If the float structure descends to the bottom of the base body, it will automatically stop drawing in cutting fluid because its U-shaped hole is blocked. Conversely, it will automatically draw in cutting fluid.

Description

[Technical Field]

[0001] This invention relates to a structure of a telescopic water-absorbing float, specifically a structure in which, regardless of whether the water-absorbing float is placed in a cutting fluid tank filled with used cutting fluid or in a cutting fluid tank without cutting fluid, the float structure automatically floats continuously above the cutting fluid surface. Simultaneously, the telescopic rod and base body assembled together in the water-absorbing float automatically extend or retract, ensuring the base body is always at the bottom of the cutting fluid tank. Thus, during use, the invention automatically presents a continuous floating float on the fluid surface, with its upper and lower through-holes positioned below the waste oil and outside the cutting fluid surface, and the base body at the bottom of the cutting fluid tank. This operational deployment mode allows for the absorption of cutting fluid without iron filings or excessive waste oil for repeated use. It is a unique, convenient, and economical invention. [Previous Technology]

[0002] Note: Commercially available used cutting fluids generally contain not only waste oil but also iron filings generated during machining. Typically, used cutting fluids are either discarded directly or collected and sent to specialized companies for filtration and separation for reuse. However, both methods increase costs for production users and fail to achieve the goal of reusing the cutting fluid. Therefore, finding a convenient and efficient way to reuse used cutting fluids containing waste oil and iron filings to reduce operating costs is a direction the industry is eagerly seeking to improve and design.

[0003] In view of this, the inventor of this case, based on his many years of research and development experience in related fields, conducted in-depth research on the aforementioned deficiencies and actively sought solutions based on the aforementioned needs. After a long period of hard work and multiple tests, he finally completed this invention, which solves the shortcomings of conventional methods and enhances its unprecedented progressiveness and practicality. [Summary of the Invention]

[0004] Therefore, the main objective of this invention is to provide a "telescopic water-absorbing float structure device", which is characterized by automatically rising or falling on the surface of the cutting fluid according to the fluid level when the water-absorbing float structure is placed to separate iron filings or reduce the content of waste oil so as to absorb used cutting fluid for reuse. There is no need to manually adjust the position and height of the through hole (i.e., suction port) in the float structure body so that the desired reusable cutting fluid can be absorbed at any time.

[0005] A secondary objective of this invention is to provide a "structural device for a telescopic water-absorbing float". When the float structure descends due to a drop in liquid level, causing the connected rods and telescopic rods to abut against the bottom end of the shaft inside the base body, the water-absorbing float structure of this invention will automatically stop absorbing the required cutting fluid because the U-shaped holes on the rods and the telescopic rods will be closed simultaneously. Conversely, if the float structure rises due to a drop in liquid level, and the U-shaped holes on the rods and the telescopic rods are opened simultaneously in a stretched connected state, it will automatically resume absorbing the required cutting fluid.

[0006] Another important objective of the present invention is to provide a "structural device for a telescopic water-absorbing float", which is mainly because the float structure has a plurality of L-shaped blocking plates distributed at 90-degree intervals. Therefore, when the required cutting fluid is drawn in through the through hole on the float structure, the narrow interval between the L-shaped blocking plates can effectively block and separate the iron filings in the used cutting fluid.

Implementation Method

[0007] In order to provide a more detailed and clear understanding of the purpose, effects and structural features of the present invention, the following preferred embodiments are described in conjunction with the accompanying drawings.

[0008] First, please refer to Figures 1 and 2. The present invention is a structural device for a telescopic water-absorbing float, which mainly comprises a base body 1, a telescopic rod 2, and a float structure 3. The base body 1 is composed of a disc seat 101, a connecting pipe 105, and an L-shaped through pipe 104. The disc seat 101 is integrally formed and has a structure including a disc seat 101, a shaft body 102, and a connecting body 103. The shaft body 102 has a vertical through hole (not shown in the figure), and the connecting body 103 also has an oblique through hole (not shown in the figure). The vertical through hole and the oblique through hole are intersecting and communicating with each other. The connecting pipe 105 is rod-shaped, with a hexagonal block 1051 in the middle. The upper section of the hexagonal block 1051 has an upper screw 1052, the end of which has a through hole 1054. Inside the end of the through hole 1054, there is an inner ring channel (not shown in the figure). The lower section has a lower screw 1053, which is screwed into the internal threaded hole (not shown in the figure) of the shaft 102 of the disc seat 101 and assembled with the disc seat 101 to form an integral part. The L-shaped tube 104 has a tapered stepped section 1042 at one end, with an outlet section 1041 in the center, and a threaded rod section (not shown in the figure) at the other end. The threaded rod section can be screwed into the threaded hole section (not shown in the figure) in the connecting body 103 of the disc seat 101, and is assembled with the disc seat 101 to form an integral part.

[0009] The telescopic rod 2 is in the shape of a hollow circular strip with a through hole 203 in the center. There is an inner ring (not shown in the figure) on the inner side of the through hole 203 near the port. There is a U-shaped hole 202 at the lower end. There is a protruding ring 201 at an appropriate position above the U-shaped hole 202.

[0010] The float structure 3 is composed of a blocking cup body 303, a cross connector body 302, a screw plate body 304, a rod body 301, four float bodies 4, four screws 5, four washers 6 and four nuts 7. The blocking cup body 303 is composed of a plurality of L-shaped blocking plates 3031 arranged in an array with fixed intervals 3032 to form a U-shaped body, with a circular hole 3033 at the bottom center (please refer to Figure 4).

[0011] The cross connector 302 has an arc portion 3023 at its center, which can accommodate the blocking cup 303. At the upper, lower, left and right ends of the arc portion 3023, there is an L-shaped fixing piece 3021 that is upright at 90 degrees. At the center of the L-shaped fixing piece 3021, there is a hole 3022.

[0012] The screw fastener body 304 (see Figure 4 for reference) is hexagonal in shape and has a threaded hole 3041 in the center.

[0013] The rod body 301 is in the shape of a hollow round strip with an upper through hole 308 in the center, a threaded part (not shown in the figure) on the outer periphery at the upper end, a U-shaped hole 306 at the lower end, and a protruding ring 305 at an appropriate position above the U-shaped hole 306.

[0014] The float body 4 is a hollow, short, circular body with a chamfered arc shape at each of its two end faces and a through hole 401 in the center.

[0015] During assembly (see Figures 1 and 2), first complete the assembly of the float structure 3. That is, first pass the threaded part at the top of the rod 301 through the slot 3022 at the bottom center of the cross connector 302. Then place the blocking cup 303 on the arcuate part 3023 at the bottom center of the cross connector 302, so that a circular hole 3033 at the bottom center of the blocking cup 303 also passes through the rod 301. Then screw the fastening plate 304 into the threaded part at the top of the rod 301. The blocking cup 303 and the cross connector 302 can be screwed onto the top of the rod 301. Then, the screw 5 is passed through the washer 6, then through the through hole 401 of the float body 4, and then through the slot 3022 of the L-shaped fixing piece 3021 of the cross connector 302, and then screwed in with the nut 7. In this way, a single float body 4 can be individually fixed on the L-shaped fixing piece 3021 of the cross connector 302. The other three float bodies 4 are screwed in the same way, so it will not be described in detail. In this way, the assembly of the float structure is completed. Next, the assembled float structure 3's rod 301 is inserted into the through-hole 203 of the telescopic rod 2. Then, the rod 301 with the telescopic rod 2 inserted is inserted again into the through-hole 1054 of the shaft 102 of the base body 1. At this time, since the telescopic rod 2 and the rod 301 each have a protruding ring (201, 305), when the rod 301 is inserted into the telescopic rod 2, if the rod 301 is pulled upwards and the telescopic rod 2 is pulled downwards, then... The protruding ring 305 on the rod 301 will be locked in the inner ring of the end through hole 203 inside the telescopic rod 2 (not shown in the figure). Conversely, when the telescopic rod 2 is also inserted into the through hole 1054 inside the shaft body 102 of the base body 1, the telescopic rod 2 is pulled upward, and the protruding ring 201 on the telescopic rod 2 will be locked in the inner ring of the end through hole 203 inside the telescopic rod 2 (not shown in the figure). Thus, the assembly of the present invention is completed.

[0016] During operation (see Figures 3 and 4), when the used cutting fluid 11, which is mixed with iron filings 13 and waste oil 14 and fills the cutting fluid tank 8, is to be reused, the water-absorbing float 15 structure of the present invention is first placed directly in the cutting fluid tank 8. At this time, the float structure 3 will automatically float on the surface of the cutting fluid 11 due to the four float bodies 4, while the base body 1, which has its own weight, will automatically sink to the bottom of the cutting fluid tank 8. However, since the float structure 3 and the base body 1 are connected by a rod 301 and a telescopic rod 2, the rod 301 and the telescopic rod 2 will automatically extend and unfold when the base body 1 sinks automatically. This completes the setting of the water-absorbing float 15 structure of the present invention.

[0017] Please refer to Figures 1 and 5. After the structure of the water-absorbing float 15 is set up, the through hole 308 on the rod 301 will be positioned below the waste oil 14 and above the cutting fluid surface. When the hose 10 connected to the L-shaped pipe 104 of the base body 1 is pumped, the upper through hole 308 begins to draw in the cutting fluid 11 containing the smaller waste oil 14. At the same time, as shown in Figure 4, the iron filings 13 floating on the cutting fluid surface will also flow upward through hole 308. At this time, because of the multiple pieces on the cup body 303, With the L-shaped baffle 3031 blocking and the spacer 3032 allowing for open flow, the iron filings 13 will be retained outside the baffle cup 303. Only a small amount of cutting fluid 11, such as waste oil 14, will pass through the spacer 3032 and flow into the upper through hole 308. Please refer to Figure 6 for reference. The fluid will then flow out through the U-shaped hole 306 of the rod 301 into the through hole 203 of the telescopic rod 2. Next, it will flow into the connecting body 103 through the U-shaped hole 202 on the telescopic rod 2, and then be pumped into the recovery tank 9 through the L-shaped pipe 104 and the hose 10 sleeved on it (see Figure 3).

[0018] Please refer to Figures 5 and 6. Therefore, when the cutting fluid 11 is continuously drawn in, the float structure 3, due to its multiple float bodies 4, will automatically descend or the U-shaped hole 202 will rise as the cutting fluid level rises or falls, without requiring manual adjustment of the height of the float structure 3. When the cutting fluid level drops to a certain height and the float structure 3 also descends completely, the rod 301 and telescopic rod 2 connected to the float structure 3 will be completely retracted into the through hole 1054 of the shaft body 102 of the base body 1. This will cause the U-shaped hole 202 of the telescopic rod 2 to be sealed by the rod 301 and the bottom of the shaft body 102, thus preventing the through hole 308 on the float structure 3 from drawing in the desired cutting fluid, achieving an automatic sealing and no-drawing effect.

[0019] In summary, the structure of the telescopic water-absorbing float of the present invention was designed by the inventor with great care and ingenuity. It is not only practical and convenient, but also quick to assemble and use, easy to use, and has the characteristics of automated operation. It meets the requirements of the Patent Law for invention patents. Therefore, this application is filed in accordance with the law. We respectfully request the examiners of the Bureau to review and grant the patent. We are truly grateful.

[0020] However, the above description is only a preferred embodiment of the present invention and is not intended to limit the patent scope of the present invention. Therefore, all equivalent structural changes made by applying the present invention specification and application scope are similarly included within the scope of the present invention and are hereby stated.

The U-shaped body has a circular hole at its central bottom; the cross-shaped connector has an arc-shaped portion at its center, which can accommodate the blocking cup; at the top, bottom, left, and right ends of the arc-shaped portion, there is an L-shaped fixing piece standing upright at 90 degrees, and the center of the L-shaped fixing piece has a slot, which can accommodate the blocking cup; the screw plate is hexagonal in shape, with a threaded hole in its central part; the rod is hollow and elongated, with a through hole in its center, a threaded portion around its outer perimeter at the upper end, and a U-shaped hole at the lower end; a raised ring is located appropriately above the U-shaped hole; the rod thread at the top of the rod can pass through the slot at the central bottom of the cross-shaped connector, and then through the blocking cup. The circular hole at the center of the bottom of the cup body is placed on the arc-shaped part at the bottom of the center of the cross connector, and the screw plate can be screwed into the threaded part at the top of the rod body. This allows the cup body and the cross connector to be screwed onto the top of the rod. The rod system can be fitted into the through hole of the telescopic rod. When the telescopic rod is inserted into the through hole of the shaft body on the base body, the rod body can be connected to the base body at the same time. The float body is a hollow short circular body with a chamfered arc shape at each of its two end faces. There is a through hole in the center. The through hole can be used to pass through the screw and washer, and then through the slot of the L-shaped fixing piece of the cross connector.

Its upper and lower through-holes will be positioned below the waste oil and outside the cutting fluid surface. The telescopic rod and base body below the float structure will automatically extend, causing the base body to automatically sink to the bottom of the cutting fluid tank. When the pump is activated, the center of the float structure...

The baffle cup on the float structure automatically prevents iron filings floating on the fluid surface from entering the lower through-hole. The height of the float structure automatically adjusts with the cutting fluid level to ensure it remains above the fluid surface. If the float structure descends to the bottom of the base body, it automatically stops drawing in cutting fluid because the U-shaped holes are blocked; conversely, it automatically begins drawing in fluid.
