[0002] PDC is sintered from hard alloy matrix and diamond powder or a small amount of cobalt powder under high temperature and high pressure (HTHP) with cobalt as catalyst, and has excellent performance, mainly used for drilling and exploitation of oil, natural gas and the like. Cobalt promotes the formation of D-D bond between diamond particles in PDC synthesis, but has strong affinity with carbon at high temperature and low pressure, which can promote the conversion of diamond to graphite, resulting in reduced wear resistance of the composite sheet, and the difference in thermal expansion coefficient between cobalt and diamond can easily increase stress during high-temperature drilling, causing cracks in the PDC, leading to wear, chipping and tooth breakage and other forms of failure.

[0003] In order to reduce the negative effects (thermal expansion, thermal catalysis, thermal oxidation, etc.) of the binder cobalt on the polycrystalline diamond layer after synthesis, composite sheet manufacturers often use chemical and electrolytic methods to remove or partially remove cobalt from the polycrystalline diamond layer after synthesis for purification treatment, thereby improving the thermal stability of the composite sheet. Chemical method generally uses strong acid and strong base soaking to dissolve cobalt inside the composite sheet in acid and alkali solution to achieve the purpose of removal. In order to improve the rate of decobalt, high temperature, stirring, ultrasonic and other means are usually added.

[0004] During the chemical decobalt process, a decobalt sealing element is generally wrapped around the hard alloy substrate of the polycrystalline diamond composite sheet by injection molding sealing process, so that the upper polycrystalline diamond layer of the polycrystalline diamond composite sheet is exposed outside the decobalt sealing element, and the decobalt sealing element and the polycrystalline diamond composite sheet form a diamond composite sheet sealing assembly. The existing decobalt equipment for diamond composite sheet, with the authorization announcement number CN217973407U, has a plurality of through holes uniformly arranged on the support plate, and a reaction cylinder for placing decobalt liquid and diamond composite sheet sealing assembly is arranged in each through hole. When individual diamond composite sheet sealing assemblies need to be inspected, the diamond composite sheet sealing assemblies are usually directly clamped by plastic clips. Since the surface of the diamond composite sheet sealing assembly is smooth, it is easy to fall off and cause acid splashing, affecting work efficiency and posing safety hazards.

[0030] First, the technical scheme of the present application is described in general:

[0031] The polycrystalline diamond compact is often subjected to chemical or electrolytic decobalt or partial cobalt removal to purify the polycrystalline diamond layer in the polycrystalline diamond compact, thereby improving the thermal stability of the polycrystalline diamond compact. In the chemical decobalt process, a decobalt sealing element is wrapped around the hard alloy substrate of the polycrystalline diamond compact by injection molding sealing process, so that the upper polycrystalline diamond layer of the polycrystalline diamond compact is exposed outside the decobalt sealing element, and the decobalt sealing element and the polycrystalline diamond compact form a diamond compact sealing assembly.

[0032] The present application is based on the existing technology of diamond compact decobalt equipment, which directly puts the diamond compact sealing assembly into the acid solution in the reaction cylinder.

At least a bottom liquid leakage hole is arranged on the sleeve body to ensure that the acid solution is smoothly discharged when lifted, and the overall operation is convenient.

[0033] Specific embodiments of the decobalt reaction device of the present application:

[0034] The structure diagram of the decobalt reaction device of the present application is shown in Figures 1-4As shown, a decobalt reaction device includes a containing groove 1, the containing groove 1 is a square groove structure, a plurality of supporting barrels 2 are arranged in the containing groove 1, a diamond composite piece sealing assembly is placed in each supporting barrel 2 in one-to-one correspondence, acid liquid is poured into each supporting barrel 2, the diamond composite piece sealing assembly is soaked in the acid liquid for decobalt, at least part of the supporting barrels 2 are provided with an inspection sleeve 3, in order to save space and reasonably utilize resources in the embodiment, the barrel diameter of the supporting barrel 2 in which the inspection sleeve 3 is placed is slightly larger than that of the remaining supporting barrels 2 in which the diamond composite piece sealing assemblies are directly loaded, of course, in other embodiments, all the supporting barrels 2 can be provided with the same size, and the inspection sleeve 3 can be placed in any supporting barrel 2, and the remaining supporting barrels 2 in which the diamond composite piece sealing assemblies are directly loaded have a gap between the diamond composite piece sealing assemblies.

[0035] Specifically, the inspection sleeve 3 includes a sleeve body, the sleeve body is slightly smaller than the supporting barrel 2, the sleeve body has a placing space for placing the diamond composite piece sealing assembly, the inspection sleeve 3 and the diamond composite piece sealing assembly are placed in the supporting barrel 2 with the acid liquid together, a hooking part is arranged on the sleeve body to facilitate hooking, so that the diamond composite piece sealing assembly placed in the inspection sleeve 3 is lifted together with the inspection sleeve 3, and compared with being directly clamped, the diamond composite piece sealing assembly will not fall off, at least a bottom liquid leakage hole 7 is arranged on the bottom of the sleeve body, the acid liquid is discharged through the bottom liquid leakage hole 7 in the lifting process, the operation process is convenient, the safety hidden danger is eliminated, and the work efficiency is improved.

[0036] The bottom of the sleeve body is provided with the bottom liquid leakage hole 7, which can realize filtering of the acid liquid, and does not affect the inspection operation of the diamond composite piece sealing assembly, but in order to realize better filtering effect and make the liquid flow out as soon as possible without splashing in the lifting process, preferably, a side liquid leakage hole 8 is further arranged on the side wall of the sleeve body, so that the liquid is simultaneously leaked through the bottom and the side wall of the sleeve body, the liquid leakage efficiency is improved, and the acid liquid is quickly discharged into the supporting barrel 2 as soon as the lifting starts.

[0037] When considering how to arrange the side liquid leakage hole 8 on the side wall, the liquid leakage effect can be better, preferably, the side liquid leakage holes 8 are arranged in groups, each group of liquid leakage holes is uniformly arranged along the circumference of the side wall of the sleeve body, so that the side liquid leakage holes 8 are uniformly distributed along the circumference of the side wall of the sleeve body, in the lifting process, the liquid is uniformly discharged from the circumference, on the one hand, the liquid discharge efficiency is improved, and on the other hand, the inspection sleeve 3 is stable during the liquid discharge process and will not be inclined, and the reliability of the lifting is ensured. Of course, in other embodiments, a larger side liquid leakage hole 8 can be arranged on one side, and the other side of the inspection sleeve 3 can also ensure the liquid discharge efficiency and the lifting reliability.

[0038] In order to further realize the acid liquid drainage efficiency in the lifting process, so that the acid liquid flows out through the side liquid leakage hole 8 as soon as possible, preferably, the side liquid leakage hole 8 is axially arranged along the side wall of the sleeve body at least in two groups, so that multiple groups of side liquid leakage holes 8 are arranged in the axial direction, which can ensure that the acid liquid is discharged as quickly as possible through the side liquid leakage hole 8 with a shorter distance during lifting, thereby improving the drainage efficiency. Of course, in other embodiments, when the size of the sampling sleeve 3 is relatively low or the side liquid leakage hole 8 is relatively large, only one group of side liquid leakage holes 8 can be provided.

[0039] The side liquid leakage hole 8 is directly lifted by hooking tools, and the side liquid leakage hole 8 constitutes a hooking part to realize the lifting of the sampling sleeve 3. However, since the side liquid leakage hole 8 is located in the acid liquid and is deep, it is not convenient to operate. Therefore, in order to facilitate hooking and improve work efficiency, preferably, a lifting lug 9 is arranged on the top of the sleeve body, and a through hole 10 is arranged on the lifting lug 9. The lifting lug 9 and the through hole 10 constitute a hooking part, so that the lifting lug 9 is located at a higher position and can protrude out of the acid liquid. By cooperating with the through hole 10 on the lifting lug 9 through hooking tools, work efficiency is improved and lifting reliability is ensured. Of course, in other embodiments, a hook can be arranged on the top of the sleeve body, and the hooking tools can be hooked to lift.

[0040] One lifting lug 9 arranged on the sampling sleeve 3 can ensure the convenience of lifting operation, but during the lifting process, the sampling sleeve 3 may not be stable enough to shake due to one side lifting. Therefore, preferably, in the present embodiment, two lifting lugs 9 are arranged symmetrically along the top of the sleeve body. When lifting is needed, the symmetric lifting lugs 9 can be used for lifting to ensure the stability of the lifting process and make the sampling sleeve 3 more reliable in use.

Since the containing groove 1 needs a high-temperature environment, the temperature at different positions may be different. The support cylinders 2 at the four corners and the center position are arranged with the sampling sleeve 3. Specifically, the support cylinders 2 at the center and the four corners are slightly larger than those at other positions, which can realize sampling and testing of diamond composite sheet sealing assemblies at different orientations, and the sampling and testing effect is more perfect. Of course, in other embodiments, when the containing groove 1 is a ring-shaped groove, the support cylinders 2 can also be arranged in a ring-shaped array in the containing groove 1, and the support cylinders 2 at the center and the edge positions are arranged with the sampling sleeve 3.

[0042] In the prior art, the containing groove 1 is a common non-transparent box body, when it is necessary to observe the acid liquid condition, it is necessary to open the groove cover of the containing groove 1 to observe, since the acid liquid is easy to volatilize and is harmful to human body, such operation is not only troublesome but also dangerous, preferably, the adjacent supporting barrels 2 are communicated through the connecting pipes to make the liquid levels of the supporting barrels 2 consistent after being communicated, the barrel diameter of the supporting barrel 2 for placing the sampling sleeve 3 is larger than that of the other supporting barrels 2 for directly containing the diamond composite piece sealing assembly, the acid liquid is convenient to add to the communicated supporting barrels 2, can flow to the other supporting barrels 2 through one supporting barrel 2, and the liquid level consistency can be ensured, so that the decobalt effect is the same.

[0043] The side of the supporting barrel 2 with at least one edge position abutting the containing groove 1 is a transparent barrel wall, the containing groove 1 is provided with a transparent observation window 4 at the position corresponding to the transparent barrel wall, and the liquid level condition of the acid liquid is observed through the transparent observation window 4, which is safe to observe from the outside and convenient to operate. Of course, in other embodiments, the supporting barrels 2 can be independently provided, and the acid liquid with about the same capacity is added to each supporting barrel 2. Since the sizes of the supporting barrels 2 except the supporting barrel 2 for placing the sampling sleeve 3 are the same, one transparent observation window 4 can be arranged in each of the supporting barrel 2 for placing the sampling sleeve 3 and the other supporting barrels 2, and the observation effect can be achieved.

[0044] Since the acid liquid is easy to volatilize, in order to ensure better decobalt effect, preferably, the containing groove 1 is provided with a sealing element 5 at the top, the containing groove 1 is provided with a sealing cover 6, the sealing cover 6 and the containing groove 1 are matched and sealed, the sealing property of the decobalt reaction device is ensured, and the volatilization rate of the acid liquid is slowed down.

[0045] From the above description of the specific embodiments of the decobalt reaction device of the utility model, it can be seen that the decobalt reaction device of the utility model can support the acid liquid and the diamond composite piece sealing assembly in the multiple supporting barrels in the containing groove respectively, can trace each diamond composite piece sealing assembly, at least part of the supporting barrels are provided with the sampling sleeve, when it is necessary to inspect the diamond composite piece sealing assembly, the hooking tool is hooked on the hooking part on the sleeve body to lift the whole sleeve body, since the sleeve body is provided with at least a bottom liquid leakage hole at the bottom, the acid liquid is discharged through the bottom liquid leakage hole in the lifting process, the operation process is convenient, and the diamond composite piece sealing assembly is lifted in the sampling sleeve, compared with being directly clamped, will not fall off, the safety hidden danger is eliminated, and the work efficiency is improved.
