Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and more specifically, to an external sludge removal device for a mud tank. Background Technology

[0002] In oil drilling, tunnel excavation, and building foundation pit construction, mud tanks are crucial equipment for storing and circulating mud. With prolonged use, a large amount of sludge gradually accumulates inside the mud tank. This not only reduces the quality and performance of the mud but can also cause blockages in the mud pipelines, affecting the normal operation of the entire mud system. Currently, traditional mud tank cleaning methods mainly include manual cleaning and cleaning with built-in cleaning devices. Manual cleaning is inefficient, labor-intensive, and poses safety hazards such as falls and poisoning. Built-in cleaning devices are constantly exposed to the mud environment, making them susceptible to corrosion and wear. Maintenance requires stopping the machine to clean the tank, severely impacting construction progress and increasing maintenance costs.

[0003] A search revealed that Chinese Patent Publication No. CN201003386Y discloses "a cleaning device for drilling mud tanks, comprising a high-pressure input device for mud or cleaning fluid and a mud tank. An annular cleaning pipe, connected to the high-pressure input device, is horizontally arranged at the lower part of the mud tank. The cleaning pipe is close to the bottom and four sides of the mud tank. Spray nozzles are spaced apart on the pipe wall, with each nozzle facing at least the connection between the bottom and four sides of the mud tank. This invention has a simple structure, low manufacturing cost, and can effectively clean the mud tank with good cleaning results, preventing sedimentation and caking of the mud in the tank, thus ensuring the orderly operation of oilfield production." However, it still has the following drawbacks: (1) In actual use, the device is a built-in structure. When maintaining the cleaning pipe and spray nozzle, it may be necessary to disassemble part of the mud tank structure, which increases the maintenance difficulty and cost. (2) In actual use, the device is a fixed structure, and the position and angle of the cleaning pipe and spray nozzle are relatively fixed, making it difficult to make flexible adjustments according to the actual situation inside the mud tank. It may be necessary to replace different models of cleaning pipes or spray nozzles, which increases the complexity and cost of operation. Therefore, an external mud tank dredging device is proposed. Utility Model Content

[0004] The purpose of this invention is to address the problems of existing devices, which are either internal structures that require disassembling parts of the mud tank for maintenance of the cleaning pipe and nozzle, increasing maintenance difficulty and cost, or fixed structures where the position and angle of the cleaning pipe and nozzle are relatively fixed and difficult to adjust flexibly according to the actual conditions inside the mud tank, potentially requiring the replacement of different models of cleaning pipes or nozzles, thus increasing operational complexity and cost. This invention provides an external mud tank dredging device to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: The present invention is as follows: an external sludge removal device for a mud tank, including a base, a crushing component for high-pressure crushing of the sludge inside the mud tank being provided on the top of the base, and an adjustment component for flexibly adjusting the height and angle of the device being provided on one side of the base. The crushing assembly includes an outer telescopic rod located on the top of the base. A sliding groove is formed on one side of the outer telescopic rod, within which an inner telescopic rod is slidably installed. A first hydraulic rod is hinged to one side of the outer telescopic rod, with the end of the first hydraulic rod furthest from the outer telescopic rod hinged to one side of the inner telescopic rod. A high-pressure pipeline is fixedly installed inside the inner telescopic rod. A rotating nozzle is located on one side of the high-pressure pipeline, and multiple spray nozzles are fixedly installed around the periphery of the rotating nozzle. A placement groove is formed on one side of the base, within which a high-pressure pump is fixedly installed. A pulse generator is mounted on the high-pressure pump, and a rubber hose is connected to the outlet of the high-pressure pump. The rubber hose is connected to the high-pressure pipeline.

[0006] As a preferred technical solution of this utility model, the adjustment component includes a hinge block welded to one side of the outer telescopic rod, the hinge block being hingedly installed on the top of the base, the outer telescopic rod being hingedly connected to the base, a first extension block being fixedly installed on one side of the base, a second hydraulic rod being hingedly installed on one side of the first extension block, a second extension block being fixedly installed on the bottom of the outer telescopic rod, and the side of the second hydraulic rod away from the first extension block being hingedly installed on the bottom of the second extension block.

[0007] As a preferred technical solution of this utility model, a placement plate is fixedly installed on the bottom of the base, four universal wheels are fixedly installed on the bottom of the placement plate, and a push handle is welded to one side of the placement plate.

[0008] As a preferred technical solution of this utility model, a display screen is provided on one side of the base, and a video camera is fixedly installed on the top of the inner telescopic rod.

[0009] As a preferred technical solution of this utility model, a control panel is provided on one side of the base, and the control panel integrates multiple sets of buttons and indicator lights.

[0010] As a preferred technical solution of this utility model, a storage groove is provided on one side of the base, a drawer is slidably installed inside the storage groove, and a handle is fixedly installed on one side of the drawer.

[0011] As a preferred technical solution of this utility model, a protective pad is adhered to the periphery of the push handle, and the protective pad is made of rubber.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. When using the device with its set crushing components, first move it to a suitable position, then start the first hydraulic rod. Its extension and retraction will cause the inner telescopic rod to slide up and down in the sliding groove of the outer telescopic rod. Adjust the length of the inner telescopic rod so that the rotating nozzle is in a suitable position. Then turn on the high-pressure pump, and the pulse generator will work to convert ordinary water flow into high-pressure pulse water flow. The water flow passes through the outlet of the high-pressure pump in the placement tank and is delivered to the high-pressure pipe in the inner telescopic rod through the rubber hose. The high-pressure pulse water flow is sprayed from multiple nozzles around the rotating nozzle to powerfully crush the sludge in the mud tank. The rotating nozzle can also rotate automatically under the reaction force of the high-pressure water flow to expand the crushing range and achieve efficient sludge removal operation. 2. With the adjustable components in place, when it is necessary to adjust the angle of the outer telescopic rod and its components to better align with the sludge areas at different heights inside the mud tank, the second hydraulic rod is activated. One end of the second hydraulic rod is hinged to the first extension block on one side of the base, and the other end is hinged to the second extension block at the bottom of the outer telescopic rod. As the second hydraulic rod extends and retracts, it pushes or pulls the outer telescopic rod. Since the outer telescopic rod is hinged to the top of the base through the hinge block, the outer telescopic rod can rotate flexibly around the hinge point, thereby changing the angle. This allows the crushing components and other parts installed on the outer telescopic rod to accurately reach the target working position, preparing for efficient subsequent dredging work.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] like Figure 1 As shown, this embodiment proposes an external sludge removal device for a mud tank, including a base 1. The top of the base 1 is provided with a crushing component 2 for high-pressure crushing of the sludge inside the mud tank, and one side of the base 1 is provided with an adjustment component 3 for flexibly adjusting the height and angle of the device. like Figure 2 and Figure 3As shown, the crushing assembly 2 includes an outer telescopic rod 201 mounted on the top of the base 1. A sliding groove 202 is provided on one side of the outer telescopic rod 201, and an inner telescopic rod 203 is slidably installed within the sliding groove 202. A first hydraulic rod 204 is hinged to one side of the outer telescopic rod 201, and the end of the first hydraulic rod 204 away from the outer telescopic rod 201 is hinged to one side of the inner telescopic rod 203. A high-pressure pipe 205 is fixedly installed inside the inner telescopic rod 203. A rotating nozzle 206 is provided on one side of the high-pressure pipe 205, and multiple nozzles 207 are fixedly installed around the rotating nozzle 206. The multiple nozzles 207 distributed around the rotating nozzle 206 powerfully spray high-pressure pulsed water flow, violently impacting the hardened and stubborn sludge in the mud tank to achieve efficient crushing. A placement groove 208 is provided on one side of the base 1, and a high-pressure pump 209 is fixedly installed inside the placement groove 208. A pulse generator is mounted on the high-pressure pump 209. 210. The outlet of the high-pressure pump 209 is connected to a rubber hose 211, which is connected to the high-pressure pipeline 205. When in use, first move the device to a suitable position, start the first hydraulic rod 204, which extends and retracts, causing the inner telescopic rod 203 to slide up and down in the sliding groove 202 of the outer telescopic rod 201. Adjust the length of the inner telescopic rod 203 so that the rotating nozzle 206 is in a suitable position. Then turn on the high-pressure pump 209, and the pulse generator 210 works accordingly, converting ordinary water flow into high-pressure pulse water flow. The water flow passes through the outlet of the high-pressure pump 209 in the placement tank 208 and is delivered to the high-pressure pipeline 205 in the inner telescopic rod 203 through the rubber hose 211. The high-pressure pulse water flow is sprayed out from multiple nozzles 207 around the rotating nozzle 206, which powerfully breaks up the sludge in the mud tank. The rotating nozzle 206 can also rotate automatically under the reaction force of the high-pressure water flow, expanding the breaking range and achieving efficient sludge removal operation.

[0020] like Figure 5As shown, the adjustment assembly 3 includes a hinge block 301 welded to one side of the outer telescopic rod 201. The hinge block 301 is hingedly mounted on the top of the base 1. The outer telescopic rod 201 is hingedly connected to the base 1. A first extension block 302 is fixedly mounted on one side of the base 1. A second hydraulic rod 303 is hingedly mounted on one side of the first extension block 302. A second extension block 304 is fixedly mounted on the bottom of the outer telescopic rod 201. The side of the second hydraulic rod 303 away from the first extension block 302 is hingedly mounted on the bottom of the second extension block 304. In use, when it is necessary to adjust the angle of the outer telescopic rod 201 and its components to better align with different parts inside the mud tank... When in areas with high levels of silt, the second hydraulic rod 303 is activated. One end of the second hydraulic rod 303 is hinged to the first extension block 302 on one side of the base 1, and the other end is hinged to the second extension block 304 at the bottom of the outer telescopic rod 201. As the second hydraulic rod 303 extends and retracts, it pushes or pulls the outer telescopic rod 201. Since the outer telescopic rod 201 is hinged to the top of the base 1 through the hinge block 301, the outer telescopic rod 201 can rotate flexibly around the hinge point, thereby changing the angle. This allows components such as the crushing assembly 2 installed on the outer telescopic rod 201 to accurately reach the target working position, preparing for efficient subsequent dredging work.

[0021] like Figure 2 As shown, a placement plate 4 is fixedly installed on the bottom of the base 1, and four casters 5 are fixedly installed on the bottom of the placement plate 4. A push handle 6 is welded to one side of the placement plate 4. When in use, the operator first walks to the push handle 6 welded to one side of the placement plate 4, holds the push handle 6 with both hands, and because four casters 5 are fixedly installed on the bottom of the placement plate 4, the device can be pushed to move in the target direction, easily reaching a suitable position near the mud tank, making the whole movement process labor-saving and convenient, and improving work efficiency.

[0022] like Figure 2As shown, a display screen 7 is installed on one side of the base 1, and a visual camera 8 is fixedly installed on the top of the inner telescopic rod 203. When in use, the staff first moves the device to a suitable position near the mud tank using the push handle 6 and the universal wheels 5 and fixes it. After the device is turned on, the visual camera 8 on the top of the inner telescopic rod 203 starts to work. It can capture the image inside the mud tank in real time, including the distribution and thickness of the sludge and whether there are foreign objects, and transmit this image information to the display screen 7 on one side of the base 1. The staff can stand in front of the display screen 7 and clearly and intuitively understand the situation inside the mud tank without having to risk entering the tank to check. According to the image displayed on the display screen 7, the staff can precisely control the adjustment component 3 to adjust the height and angle of the inner telescopic rod 203 so that the crushing component 2 can reach the key position of the sludge accumulation. At the same time, the staff can also reasonably control the working parameters of the crushing component 2 based on the image feedback, such as the pressure of the high-pressure pump 209 and the spray force of the rotating nozzle 206, to ensure that the dredging work is carried out efficiently and accurately, which greatly improves the safety and efficiency of the operation.

[0023] like Figure 4 As shown, a control panel 9 is provided on one side of the base 1. The control panel 9 integrates multiple sets of buttons 10 and indicator lights 11. When in use, the device is powered on, and the power indicator light 11 on the control panel 9 will light up, indicating that the device has been successfully powered on. The video camera 8 will transmit the real-time image of the mud tank to the display screen 7. The staff can easily control the operation of each component by touching the buttons 10 on the control panel 9 with reference to the image. At the same time, the pressure of the high-pressure pump 209 and the rotation speed of the rotating nozzle 206 can be flexibly adjusted through the control panel 9 to flexibly deal with different sludge conditions. During the dredging process, if the equipment malfunctions, the indicator light 11 will light up and flash quickly to remind the staff to deal with it in time.

[0024] like Figure 5 As shown, a storage slot 12 is provided on one side of the base 1. A drawer 13 is slidably installed inside the storage slot 12. A handle 14 is fixedly installed on one side of the drawer 13. In use, the storage slot 12 provides a fixed and orderly space for the drawer 13. When it is necessary to retrieve items in the drawer 13, such as dredging tools or spare parts, the staff can hold the handle 14 fixed on the side of the drawer 13 and apply an outward pulling force. The drawer 13 will then be easily pulled out to make it convenient to retrieve items. After use, the drawer 13 can be pushed back into the storage slot 12 through the handle 14 to return it to its original position, thus achieving orderly storage and convenient retrieval of items.

[0025] like Figure 5As shown, a protective pad 15 is attached to the periphery of the push handle 6. The protective pad 15 is made of rubber. When in use, the operator holds the push handle 6 with both hands to move the external sludge removal device of the mud tank. At this time, the rubber protective pad 15 attached to the periphery of the push handle 6 has good softness and elasticity. When the operator holds the push handle 6, it can fit tightly against the palm, effectively increasing the friction between the hand and the push handle 6. Even if the hand is sweaty or the device is in a relatively humid environment, it can prevent the hand from slipping, allowing the operator to steadily control the movement direction of the device and avoid collisions with surrounding objects or people due to slipping.

[0026] Specifically, when using this external sludge removal device for the mud tank: first, move the device to a suitable position, then activate the first hydraulic rod 204. Its extension and retraction cause the inner telescopic rod 203 to slide up and down within the sliding groove 202 of the outer telescopic rod 201. Adjust the length of the inner telescopic rod 203 so that the rotating nozzle 206 is in the appropriate position. Next, turn on the high-pressure pump 209, and the pulse generator 210 will then operate, converting ordinary water flow into high-pressure pulse water flow. The water flow passes through the outlet of the high-pressure pump 209 in the placement tank 208 and is delivered through the rubber hose 211 to the high-pressure pipe 205 inside the inner telescopic rod 203. The high-pressure pulse water flow is ejected from multiple nozzles 207 around the rotating nozzle 206, powerfully breaking up the sludge in the mud tank. The rotating nozzle 206 can also automatically rotate under the reaction force of the high-pressure water flow, expanding the breaking range and achieving efficient sludge removal operations (e.g., Figure 2 and Figure 3 As shown), when it is necessary to adjust the angle of the outer telescopic rod 201 and its components to better align with the sludge areas at different heights inside the mud tank, the second hydraulic rod 303 is activated. One end of the second hydraulic rod 303 is hinged to the first extension block 302 on one side of the base 1, and the other end is hinged to the second extension block 304 at the bottom of the outer telescopic rod 201. As the second hydraulic rod 303 extends and retracts, it pushes or pulls the outer telescopic rod 201. Since the outer telescopic rod 201 is hinged to the top of the base 1 through the hinge block 301, the outer telescopic rod 201 can rotate flexibly around the hinge point, thereby changing the angle. This allows the crushing components 2 and other components installed on the outer telescopic rod 201 to accurately reach the target working position, preparing for the subsequent efficient dredging work (such as...). Figure 5 (As shown).

[0027] All technical features in this embodiment can be freely combined according to actual needs.

[0028] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
