Description

Technical Field

[0002] When drilling on the road of a nuclear power project, the exploration point is generally arranged on the side of the main road in the city. The ground is generally completely solidified, and mud pools are not allowed to be dug on the ground. During the survey and construction, mud discharge will seriously pollute the urban ground environment and even block the municipal drainage pipes. Traditionally, mud treatment is generally to cover the sandbags with plastic film, and then discharge the mud into the sandbags. After the sandbags are full, they are sealed and then transported out for treatment. This method has a slow construction speed, and the plastic film is easy to break, causing leakage and polluting the environment. There are also some mud troughs made by drilling workers, such as four square steels fixed by bolts, geotextiles or sponges are laid on the bottom, and a square trough structure with an outlet is formed to block mud and water turbulence. However, this homemade mud trough has a simple structure, lacks stability, and is prone to deformation or collapse during the drilling process, resulting in leakage, and it is also impossible to completely collect all the mud, resulting in some mud still leaking into the environment after being filled, which is less practical.

DETAILED DESCRIPTION

[0014] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0015] See also Figure 1-9 The present invention provides a technical solution for an engineering drilling mud treatment device: Example

[0016] The present embodiment provides an engineering drilling mud processing device, including a mud tank 1, a collecting tank 2, a constant pressure tank 3 and an air pump 4, etc. The inlet of the collecting tank is connected to the bronchial tube inside the square steel constituting the mud tank, and the air suction port 7 of the collecting tank is connected to the constant pressure tank 3 through the air suction pipe. The constant pressure tank 3 is controlled by the air pump 4, so that the inner cavity of the collecting tank and the constant pressure tank always maintains a horizontal negative pressure state, and at the same time, the square steel is fixed to the ground through the suction bowl at the bottom, so that the mud and water sprayed out from the borehole during engineering drilling can be collected in the mud tank 1, and the mud and water can be collected into the collection tank 2 through the main pipe 5 through the negative pressure suction effect.

[0017] Specifically, Figure 1 and Figure 3 As shown, the mud trough is made of multiple square steels. In this embodiment, four square steels are connected end to end to form a square slurry chamber 13. The mud trough structure is placed around the borehole to collect the splashed mud water. Figure 3As shown, each square steel has the same appearance structure, and the main body is a rectangular parallelepiped structure. A plug 19 extends from one end, and a socket 20 is opened inside the square steel at the other end. In this way, the plug of one square steel is vertically inserted into the socket of another square steel, and then the two square steels are fixed together by through screws. Four square steels can be fixedly assembled into a mud trough structure that can hold mud and water.

[0018] Furthermore, if Figure 4 As shown, the interior of each square steel is a double-layer structure, that is, the square steel body is provided with an upper cavity 21 and a lower cavity 23 along its extension direction, and the upper cavity is fixedly provided with a bronchus 22, and the bottom of the lower cavity 23 is an open structure, and a suction cup 17 is fixedly provided inside. The suction cup may be made of rubber material, and through grooves are evenly provided between the upper cavity and the lower cavity. A connecting pipe 24 is matched and provided inside the through groove, that is, the top of the connecting pipe is connected to the bronchus 22 in the upper cavity, and the bottom is connected to the inner cavity of the suction cup 17. In this way, when negative pressure suction is performed on each bronchus, negative pressure can be formed inside the suction cup through the connecting pipe 24, so that the suction cup is tightly adsorbed on the ground, so that a barrier is formed around the bottom of the mud trough to constitute a slurry chamber for collecting mud and water.

[0019] In the arrangement of the present invention, the bronchus in the upper cavity is used to connect to the collection system, and the suction cup in the lower cavity is connected to the upper cavity through a connecting tube, forming a negative pressure adsorption system, which combines the concepts of negative pressure suction and modular splicing, not only enhances the stability of the structure, but also cleverly utilizes the negative pressure principle to achieve adsorption on the ground, improves the efficiency of mud collection, and facilitates flexible deployment at complex and changeable drilling sites.

[0020] like Figure 5 As shown, a three-way pipe 25 is connected to the end of the bronchial pipe in one of the square steels to realize the suction of muddy water in the slurry chamber 13. Specifically, as Figure 2 and Figure 5 As shown, a pumping pipe 15 is provided inside the square steel, a valve 14 is provided on the pumping pipe, a water level sensor 12 is fixedly installed on the square steel near the valve, a connecting pipe 18 is provided outside the square steel, and the inside of the three-way pipe 25 is connected to the pumping pipe 15, and the outside is connected to the connecting pipe 18. In this way, when the valve 14 is closed, negative pressure suction is achieved only through each bronchus 22 and the suction bowl, so that the mud trough is tightly adsorbed on the ground, and when the depth of muddy water in the slurry chamber reaches the set height of the water level sensor 12, the water level sensor alarms, and the valve is automatically opened by the controller, so that the muddy water in the slurry chamber is sucked into the inner cavity of the collection tank 2 through the pumping pipe 15 and then through the three-way pipe 25 and the connecting pipe 18, which can prevent the muddy water in the slurry chamber from overflowing.

[0021] In addition, considering that the muddy water in the slurry chamber may contain some particulate impurities, which may cause blockage of pipelines at all levels, a filter screen can be installed at the end of the pumping pipe by bolts to prevent pipeline blockage and improve pumping efficiency; the filter screen is detachable for easy cleaning and replacement.

[0022] like Figure 1 and Figure 6 As shown, the output end of the connecting pipe 18 is connected to the inlet 10 of the collecting tank 2 through the main pipe 5. The collecting tank is a horizontal structure with a support 8 at the bottom. The top of the tank body is provided with an inlet 10 and an air suction port 7. The air suction port 7 is connected to the constant pressure tank 3 through the air suction pipe 6 to maintain a constant negative pressure state inside the collecting tank. A slurry discharge port 9 is installed at the bottom of the tank body. The slurry discharge port is in a normally closed state. The interior of the collecting tank maintains a constant negative pressure. When the valve 14 is opened, muddy water can flow into the interior of the collecting tank through the inlet 10. When the drilling work is completed, the muddy water in the tank body can be discharged by opening the slurry discharge port 9 at the bottom, thereby effectively realizing the collection, storage and discharge of mud. Figure 1 and Figure 7 As shown, the constant pressure tank 3 and the air pump 4 are placed on the base 30. The constant pressure tank is connected to the collection tank 2 through the air extraction pipe. The constant pressure tank is controlled by the air pump, and the air pressure in the constant pressure tank is controlled by the air pump to maintain a constant negative pressure state in the constant pressure tank and the collection tank. Furthermore, a pressure detection device, such as a pressure gauge, can be added to the collection tank and the negative pressure tank to adjust the negative pressure according to actual needs to avoid damage to the system caused by excessive or insufficient negative pressure.

[0023] The present invention provides an engineering drilling mud processing device. When it is actually used, the pipelines are connected accordingly, the valve 14 is kept closed, the collecting tank is assembled and fixed, and then placed around the borehole. The air pump 4 controls the constant pressure tank 3 to maintain a constant negative pressure state in the inner cavity of the collecting tank 2 and the constant pressure tank 3, and transmits the air to the suction cup 17 through the bronchus, so that the suction cup 17 is adsorbed on the ground under the action of negative pressure to keep the mud tank 1 stable. During the drilling process, the mud carries the rock cuttings into the slurry chamber 13 of the mud tank. When the depth of mud and water in the slurry chamber reaches the height set by the water level sensor 12, the water level sensor controls the water level sensor 12 to increase the pressure. The device sends a signal, and the controller automatically opens the valve after receiving the signal, allowing the muddy water to be sucked into the collection tank 2 through the pumping pipe 15, the three-way pipe 25, the connecting pipe 18 and the main pipe 5. Due to the effect of constant negative pressure, the muddy water can be stably stored in the tank; when the muddy water in the slurry chamber is completely sucked into the collection tank, the valve 14 is closed, and the slurry discharge port 9 at the bottom of the collection tank is opened to discharge the muddy water in the tank to the designated treatment area. After the discharge is completed, the slurry discharge port 9 is closed, and the collection tank is cleaned and maintained to prepare for the next use; at the same time, the residual mud sediment in the slurry chamber is cleaned.

[0024] The engineering drilling mud processing device provided by the present invention is easy to assemble and disassemble and has strong flexibility. It uses a suction cup to be adsorbed on the ground through the negative pressure principle, thereby enhancing the stability of the mud tank. It can remain stable even in complex and changeable construction sites and has strong stability. Through the coordinated use of a constant pressure tank and an air pump, a constant negative pressure state inside the collection tank can be maintained to ensure that mud and water can be stably stored and pumped. The present invention effectively collects and processes mud, reduces pollution to the environment, and meets the environmental protection requirements of modern engineering. Example

[0025] On the basis of Example 1, Figure 8 and Fig. 9 As shown, the similarities between this embodiment and embodiment 1 are not repeated here, except that the matching of the plug and the socket between each square steel can also be set to the structure described in this embodiment, such as Figure 8 As shown, one square steel structure is defined as a plug-in body 101, and the other is a plugged body 202. A plug connector 103 is provided at the end of each plug-in body 101, and a plug slot 203 is opened inside the other end, that is, one square steel structure can be used as both a plug-in body and a plugged body. Multiple plug-in bodies 101 are matched and fixedly inserted into the plugged body, and are connected end to end to form a mud tank.

[0026] Furthermore, a connecting groove 104 is provided on the upper side of one side of the plug connector 103, and the connecting groove is connected to the airflow channel I102 inside the plug body 101. A groove 108 perpendicular to the airflow channel I is provided on the side of the connecting groove away from the airflow channel I, and a pin tube 105 is matched and provided in the groove. The pin tube is hollow inside, and a side hole 106 is provided on the side close to the connecting groove 104. The bottom of the pin tube is a closed structure, and is fixed and adsorbed inside the groove 108 by a magnet 107.

[0027] like Figure 8 As shown, a fixed block 204 is installed inside the plug-in slot 203 of the plug-in body 201. The fixed block is a solid structure with an installation slot on the right side. A spring 205 is fixedly installed in the installation slot. The spring is fixedly connected to a spring seat 206 on the deep side wall of the plug-in slot 204 in the transverse direction. A moving cavity 207 connected to the plug-in slot is opened above the fixed block. A stopper 208 is provided on the top of the moving cavity, and the moving cavity is connected to the airflow channel II of the plug-in body 201. Under the action of the spring, the fixed block is naturally located in the middle of the plug-in slot and blocks the moving cavity, so that the airflow in the airflow channel II 202 cannot flow into the plug-in slot.

[0028] When the plug connector 103 of the plug body 101 is matched and inserted into the plug slot 203 on the plugged body 201, as shown in FIG. Fig. 9As shown, the pin tube 105 presses the fixed block 204 to move it inward, and at the same time the spring is compressed. When the plug connector 103 is completely inserted into the plug-in slot, due to the negative pressure inside the air flow channel II 202, the pin tube 105 is sucked upward, so that the magnetic adsorption effect of the magnet disappears, until the pin tube is adsorbed to the top and contacts the baffle in the movable chamber 207, and at the same time the side hole 106 on the pin tube is connected with the connecting slot 104. At this time, under the action of the pin tube, the air flow channel II and the pin tube 105, as well as the connecting slot 104 and the air flow channel I are connected with the air flow, and the upper part of the pin tube body is located in the movable chamber 207, and the lower part is located in the groove 108 of the plug connector, so that the plug connector 103 is fixedly inserted in the plug-in slot 203 under the action of negative pressure suction, thereby realizing the fixed plug-in connection between the four square steels, which together form a mud tank.

[0029] The arrangement of this embodiment utilizes the negative pressure system to form a self-sealing and self-locking matching relationship between each square steel. After each square steel structure is installed, it is only necessary to maintain the negative pressure state of the air flow channel inside the square steel through the air pump, so that the internal air flow channel forms a negative pressure environment. Under the continuous action of negative pressure, the plug connector is firmly fixed in the plug slot, and these square steels will automatically form a tight connection. This connection method does not require additional fasteners or manual operation, which greatly improves the installation efficiency and connection reliability. At the same time, due to the sealing effect of negative pressure, leakage is not easy to occur at the connection, and when the square steel needs to be disassembled or replaced, it is easy to do by simply turning off the air pump and releasing the negative pressure, which significantly improves the on-site construction efficiency and connection reliability, while also reducing maintenance costs and difficulty of use.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
