Description

Technical Field

[0001] The invention relates to the technical field of drilling sludge treatment, in particular to a drilling sludge water recycling mechanism and method with high efficiency filtration. Background Art

[0002] The drilling process generates drilling sludge, which is usually a mixture of debris and mud produced when the drill bit cuts through the strata or rock. When handling drilling sludge, it is necessary to comply with local environmental laws and regulations to ensure that the treatment method meets environmental requirements, especially when drilling surveys are carried out in areas with strict environmental protection, such as urban built-up areas.

[0003] When conducting exploration drilling in urban built-up areas, the drill bit needs to be replenished with water, so a lot of sludge water is often retained in the drilling area. Since the drill bit needs to be replenished with water during the drilling process, the sludge water is not convenient to be extracted and collected by other equipment during the drilling process. After the drilling process, it is difficult to reuse the sludge water. In this regard, an efficient filtration drilling sludge water recycling mechanism and method are proposed to solve the above-mentioned problems. Summary of the invention

[0004] 1. Technical issues to be solved

[0006] (II) Technical solution

[0007] In order to achieve the above-mentioned purpose of recycling sludge water during the survey process, reducing the water consumption during the drilling process and the sludge remaining in the borehole, the present invention provides the following technical solutions: a high-efficiency filtering drilling sludge water recycling mechanism, comprising a water tank, the water tank is continuously divided into a first water tank, a second water tank and a third water tank from left to right, the first water tank, the second water tank and the third water tank are connected through a filter plate, the bottom of the first water tank is open and detachably equipped with a drilling casing, the top of the water tank is fixedly installed with a tank cover, and the tank cover is provided with a filter press device;

[0008] The filter press device includes a cylinder fixed on the box cover and a pressure plate connected to the cylinder. The pressure plate also includes a panel made of a mesh material and a plate frame for fixing the panel. A ring corresponding to the drilling casing is also fixedly installed on the panel.

[0009] Preferably, a sealing ring is embedded in the bottom of the first water tank and fits tightly to the outside of the drilling casing.

[0010] Preferably, a fixing plate for connection is fixedly mounted on the piston rod of the cylinder, an extension rod is fixedly mounted on the fixing plate, a connecting plate is fixedly mounted on the end of the extension rod, and the connecting plate is fixedly connected to the pressure plate by bolts.

[0011] Preferably, the connecting plate, the box cover and the fixing plate are all provided with openings for the drilling equipment to pass through.

[0012] Preferably, a baffle is provided inside the second water tank, and the number of the baffles is several, and the several baffles are staggered and arranged at the front and rear sides of the second water tank.

[0013] Preferably, a T-shaped plug-in block is fixedly mounted on the end of the baffle, and a socket for plugging the plug-in block is fixedly mounted on the inner wall of the second water tank.

[0014] Preferably, the heights of the two filter plates and the drilling casing are lower than the height of the water tank, and a water supply pipe and a drainage pipe are connected to the side of the third water tank.

[0015] A method for recycling drilling sludge water with high efficiency filtration comprises the following steps:

[0016] S1. After determining the survey drilling position, clean the drilling position, align the preset hole with the opening at the bottom of the water tank and place the water tank. At this time, close the tank cover to complete the setting of the pressure plate, and then extend the drill bit of the drilling rig equipment through the fixed plate, the tank cover and the pressure plate and into the inside of the drilling casing to complete the equipment setting;

[0017] S2, water is added to the water tank through the water supply pipe until the liquid level in the water tank exceeds the drilling casing by a certain distance, at which time the water in the water tank falls downward into the drilling hole through the upper end of the drilling casing, and the drilling rig is turned on to perform the drilling operation;

[0018] S3. During the operation, drilling continuously generates fine debris mixed with clean water to form sludge water. The sludge water flows upward along the drill bit and the borehole casing to the first water tank for storage. The cylinder is controlled to push the fixed plate, the extension rod and the connecting plate to move, so that the pressing plate at the lower end of the connecting plate can squeeze the sludge water downward in the first water tank. The sludge contained in the sludge water is precipitated in a viscous state at the bottom of the first water tank, and the remaining water is filtered through the filter plate connected between the first water tank and the second water tank and then discharged into the second water tank;

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-3 A high-efficiency filtering drilling sludge water recycling mechanism includes a water tank 1, which is continuously divided into a first water tank 101, a second water tank 102 and a third water tank 103 from left to right. The first water tank 101, the second water tank 102 and the third water tank 103 are used for different functions respectively, and the first water tank 101, the second water tank 102 and the third water tank 103 are connected through a filter plate 2, so that water can flow among the first water tank 101, the second water tank 102 and the third water tank 103.

[0030] It should be noted that the bottom of the first water tank 101 is open and detachably equipped with a drilling casing 4, which is used to connect a drill bit. Since the bottom of the first water tank 101 is open, the drill bit can pass through the drilling casing 4 and the opening to perform drilling and surveying toward the bottom of the water tank 1.

[0031] Preferably, a sealing ring 5 is embedded in the bottom of the first water tank 101 and fits tightly to the outside of the drilling casing 4. Through the setting of the sealing ring 5, the water in the drilling area can only flow toward the opening at the lower end of the first water tank 101, that is, return upward along the drilling casing 4.

[0032] In this embodiment, a tank cover 3 is fixedly installed on the top of the water tank 1, and a filter press device for efficiently filtering the sewage in the first water tank 101 is provided on the tank cover 3. The filter press device includes a cylinder 11 fixed on the tank cover 3 and a pressure plate 15 connected to the cylinder 11. The pressure plate 15 corresponds to the size of the first water tank 101. By pressing the pressure plate 15 downward, the sludge water in the first water tank 101 can be forced to pass through the filter plate 2 for filtration.

[0033] It should be noted that a fixing plate 12 for connection is fixedly installed on the piston rod of the cylinder 11, an extension rod 13 is fixedly installed on the fixing plate 12, a connecting plate 14 is fixedly installed on the end of the extension rod 13, and the connecting plate 14 is fixedly connected to the pressure plate 15 by bolts. The connecting plate 14 and the fixing plate 12 form an I-shaped structure, and the cylinder 11 can drive the pressure plate 15 to move synchronously.

[0034] It is worth noting that the pressing plate 15 also includes a panel 151 made of a mesh material and a plate frame 152 for fixing the panel 151. A ring 153 corresponding to the drilling casing 4 is also fixedly installed on the panel 151. Through the setting of the ring 153, the pressing plate 15 can avoid squeezing the drilling casing 4 during the pressing process.

[0035] Preferably, the connecting plate 14, the box cover 3 and the fixing plate 12 are all provided with openings for the drilling equipment to pass through, so as to facilitate extending the drilling equipment to the lower end of the drilling casing 4 to perform drilling operations.

[0036] In the present application, a box body 1 is placed outside the drilling position, and a drilling casing 4 extending toward the box body 1 is provided to provide a sludge water backflow storage space, so that the sludge water only stays inside the drilling hole and the water tank 1, thereby avoiding the accumulation of sludge water and the problem of inconvenience in circulation and filtration during use.

[0037] Furthermore, in order to recycle the sludge water, in the present embodiment, a baffle 6 is provided inside the second water tank 102. The number of baffles 6 is several, and the baffles 6 are staggered and arranged on the front and rear sides of the second water tank 102, so that the sludge water can flow in the second water tank 102 along an S-shaped trajectory after being filtered by the filter plate 2, so as to increase the flow path of the sludge water, so that the drilling sludge water can be fully precipitated and filtered in this water tank, and then discharged to the third water tank 103 through the filter plate 2.

[0038] It can be understood that a T-shaped plug-in block 9 is fixedly installed at the end of the baffle 6, and a socket 10 for plugging into the plug-in block 9 is fixedly installed on the inner wall of the second water tank 102. Through the setting of the socket 10 and the plug-in block 9, the baffle 6 can be flexibly replaced relative to the second water tank 102.

[0039] Preferably, the third water tank 103 is a clean water tank for collecting and storing clean water after pressure filtration and sedimentation filtration. It is worth noting that the heights of the two filter plates 2 and the drilling casing 4 are lower than the height of the water tank 1 .

[0040] In addition, a water supply pipe 8 and a drainage pipe 7 are connected to the side of the third water tank 103 .

[0041] It can be understood that the clean water after filtration is stored in the third water tank 103 , and at this time the filtered water can be discharged through the drain pipe 7 for reuse.

[0042] In another embodiment, when the amount of water returned from the drill bit of the drilling equipment is too small to support the water demand of the drilling rig, water is replenished toward the third water tank 103 through the water replenishment pipe 8, so that the water level in the water tank 1 rises to above the drilling casing 4, so that clean water can supply water to the drilling rig.

[0043] A method for recycling drilling sludge water with high efficiency filtration comprises the following steps:

[0044] S1. After determining the survey drilling position, clean the drilling position, align the preset hole with the opening at the bottom of the water tank 1 and place the water tank 1. At this time, close the box cover 3 to complete the setting of the pressure plate 15. Then, the drill bit of the drilling rig equipment passes through the fixed plate 12, the box cover 3 and the pressure plate 15 and extends to the inside of the drilling casing 4 to complete the equipment setting;

[0045] S2, water is replenished toward the water tank 1 through the water replenishment pipe 8 until the liquid level in the water tank 1 exceeds a certain distance from the drilling casing 4. At this time, the water in the water tank 1 falls downward into the drilling hole through the upper end of the drilling casing 4, and the drilling rig is turned on to perform the drilling operation;

[0046] S3. During the operation, drilling continuously generates fine debris mixed with clean water to form sludge water. The sludge water flows upward along the drill bit and the borehole casing 4 to the first water tank 101 for storage. The cylinder 11 is controlled so that the cylinder 11 pushes the fixed plate 12, the extension rod 13 and the connecting plate 14 to move, so that the pressing plate 15 at the lower end of the connecting plate 14 can squeeze the sludge water downward in the first water tank 101. The sludge contained in the sludge water is precipitated into a viscous state at the bottom of the first water tank 101, and the remaining water is filtered through the filter plate 2 connected between the first water tank 101 and the second water tank 102 and then discharged into the second water tank 102;

[0047] S4. The water entering the second water tank 102 flows along the gap between the baffles 6 and gradually settles, so that the impurities contained in the water are further settled at the bottom of the second water tank 102. At this time, the water that passes through the filter plate 2 and enters the third water tank 103 is clean water, which is discharged from the water tank 1 through the drain pipe 7 and can be reused.

[0048] In summary, the high-efficiency filtered drilling sludge water recycling mechanism and method, S1, after determining the survey drilling position, clean the drilling position, align the preset hole with the opening position opened at the bottom of the water tank 1 and place the water tank 1, at this time close the box cover 3, complete the setting of the pressure plate 15, and then extend the drill bit of the drilling rig equipment through the fixed plate 12, the box cover 3 and the pressure plate 15 and extend to the inside of the drilling casing 4 to complete the equipment setting;

[0049] S2, water is replenished toward the water tank 1 through the water replenishment pipe 8 until the liquid level in the water tank 7 exceeds the drilling casing 4 by a certain distance, at which time the water in the water tank 1 falls downward into the drilling hole through the upper end of the drilling casing 4, and the drilling rig is turned on to perform the drilling operation;

[0050] S3. During the operation, drilling continuously generates fine debris mixed with clean water to form sludge water. The sludge water flows upward along the drill bit and the borehole casing 4 to the first water tank 101 for storage. The cylinder 11 is controlled so that the cylinder 11 pushes the fixed plate 12, the extension rod 13 and the connecting plate 14 to move, so that the pressing plate 15 at the lower end of the connecting plate 14 can squeeze the sludge water downward in the first water tank 101. The sludge contained in the sludge water is precipitated into a viscous state at the bottom of the first water tank 101, and the remaining water is filtered through the filter plate 2 connected between the first water tank 101 and the second water tank 102 and then discharged into the second water tank 102;

[0051] S4. The water entering the second water tank 102 flows along the gap between the baffles 6 and gradually settles, so that the impurities contained in the water are further settled at the bottom of the second water tank 102. At this time, the water that passes through the filter plate 2 and enters the third water tank 103 is clean water, which is discharged from the water tank 1 through the drain pipe 7 and can be reused.
