Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a drilling fluid flocculant feeding device. Background Technology

[0002] Drilling fluid flocculants are key chemical additives in drilling fluid waste treatment (especially in the solid-liquid separation process). Their core function is to promote the aggregation of highly dispersed, stable fine solid particles (clay, drill cuttings, etc.) in the drilling fluid into larger flocs (flocs) through mechanisms such as charge neutralization and adsorption bridging. This significantly improves the separation efficiency and treatment effect of subsequent mechanical separation equipment (such as centrifuges, filter presses, and settling tanks). The feeding device is used to add the flocculant to the drilling waste to be treated.

[0003] The existing Chinese patent publication number CN215327136U describes a safe wastewater sedimentation feeding device. According to its description, when the device is used, the reagent automatically falls into the treatment tank. This feeding method reduces the uniformity of mixing between the reagent and the wastewater and the reaction mixing efficiency.

[0004] Therefore, it is necessary to provide a new drilling fluid flocculant feeding device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a drilling fluid flocculant feeding device.

[0006] The drilling fluid flocculant feeding device provided by this utility model includes: a storage cylinder, a dosing component is mounted below the storage cylinder, and an installation component is mounted on the outside of the storage cylinder to support the storage cylinder;

[0007] The dosing assembly includes a support frame and a guide tube. Hydraulic rods are fixedly connected between the top two sides of the support frame and the storage cylinder. Multiple guide tubes are provided and fixedly connected by bolts, and one of the guide tubes is fixedly installed at the center of the bottom of the support frame.

[0008] The bottom of the feed pipe is fixedly installed with multiple drug dispensing pipes that are connected to its interior and are evenly distributed. A one-way valve is sleeved on the drug dispensing pipe. A support plate is fixedly connected to the outer wall of the feed pipe, and multiple evenly distributed stirring paddles are rotatably installed on the support plate.

[0009] Preferably, the mounting assembly includes a mounting frame, two of which are symmetrically distributed, and a drive screw rotatably connected inside the mounting frame. A motor that drives the drive screw is fixedly mounted on the mounting frame.

[0010] Preferably, a movable frame with a threaded connection is fitted on the drive screw, the inner wall of the movable frame is slidably connected to the outer wall of the support rod in the mounting frame, and screw protective sleeves are fitted between both sides of the movable frame and the corresponding mounting frame to protect the drive screw.

[0011] Preferably, the installation assembly further includes guide frames, two of which are symmetrically distributed. A sliding plate is inserted inside the guide frame and fixedly connected to the bottom of the sliding plate. The docking plate is fixedly connected to the movable frame by bolts.

[0012] Preferably, a fixedly connected protruding rod is installed on the top of the sliding plate, and a threaded limiting sleeve is fitted on the outer wall of the protruding rod. The bottom of the limiting sleeve abuts against the top of the guide frame, and both the bottom of the limiting sleeve and the top of the guide frame are provided with anti-slip protrusions to increase the friction when they abut against each other.

[0013] Preferably, the storage cylinder is provided with a fixedly connected mounting frame on its exterior. The two ends of the mounting frame are fixedly connected to the corresponding guide frames. A fixedly connected pump body is mounted on the mounting frame. The input end of the pump body is connected to the bottom of the storage cylinder. The output end of the pump body is fixedly installed with a connecting pipe. A connecting hose is provided between the connecting pipe and the fixedly installed guide pipe.

[0014] Compared with related technologies, the drilling fluid flocculant feeding device provided by this utility model has the following beneficial effects:

[0015] 1. When in use, this utility model allows the dosing component to move back and forth horizontally, and the rotating stirring paddle can also stir the waste liquid at the flocculant discharge point, thereby making the discharged flocculant more evenly mixed and diffused inside the waste liquid treatment tank, which can help improve the reaction treatment effect of flocculant and waste liquid in the later stage.

[0016] 2. This utility model uses a movable sliding plate inserted inside the guide frame. During installation, after the mounting frame is fixed to the top edge of the waste liquid treatment chamber, the sliding plate can be controlled to slide inside the guide frame according to the width of the guide frame. This allows the guide frame to smoothly place the mounting frame, its top storage cylinder, and the dosing assembly between the mounting frames on both sides, thus making the assembly of this device more flexible.

[0017] 3. This utility model, through the assembly and installation of the feed pipe, allows operators to select and assemble the corresponding feed pipe according to the specifications of the treatment tank during use.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] Please see Figures 1 to 4 The present invention provides a drilling fluid flocculant feeding device, which includes a storage cylinder 1, a dosing component 2 mounted below the storage cylinder 1, and an installation component 3 for supporting the storage cylinder 1 mounted on the outside of the storage cylinder 1.

[0026] In the embodiments of this utility model, please refer to Figures 1 to 4The dosing assembly 2 includes a support frame 21 and a guide pipe 22. Hydraulic rods 211 are fixedly connected to the top two sides of the support frame 21 and the storage cylinder 1. Multiple guide pipes 22 are provided and fixedly connected by bolts, and one of the guide pipes 22 is fixedly installed at the center of the bottom of the support frame 21. Multiple dosing pipes 221 that are connected to the bottom of the guide pipe 22 and are evenly distributed are fixedly installed therein. One-way valves 222 are sleeved on the dosing pipes 221. A support plate 23 is fixedly connected to the outer wall of the guide pipe 22, and multiple evenly distributed stirring paddles 231 are rotatably installed on the support plate 23.

[0027] It should be noted that by setting up the storage cylinder 1 and the dosing assembly 2, during later use, when the hydraulic rod 211 reciprocates, the dosing pipe 221 in the dosing assembly 2 can move up and down horizontally. During this process, the stirring paddle 231 located on the outer wall of the guiding assembly can rotate by resisting the waste liquid, thereby stirring the waste liquid at the flocculant discharge point, improving the mixing effect between the waste liquid and the flocculant. This allows the discharged flocculant to be more evenly mixed and diffused inside the waste liquid treatment tank, thus helping to improve the reaction treatment effect between the flocculant and the waste liquid in the later stage.

[0028] In the embodiments of this utility model, please refer to Figures 1 to 4 The mounting assembly 3 includes a mounting bracket 31, of which two are symmetrically distributed. A drive screw 311, rotatably connected, is mounted inside each mounting bracket 31. A motor for driving the drive screw 311 is fixedly mounted on the mounting bracket 31. A threaded movable bracket 32 ​​is fitted onto the drive screw 311. The inner wall of the movable bracket 32 ​​is slidably connected to the outer wall of the support rod in the mounting bracket 31. Both sides of the movable bracket 32 ​​and the corresponding mounting bracket 31 are fitted with screw protective sleeves to protect the drive screw 311. The mounting assembly 3 also includes a guide frame 33. 3. Two guide frames 33 are provided and symmetrically distributed. A sliding plate 331 is inserted inside the guide frame 33 and is slidably connected. A docking plate 334 is fixedly connected to the bottom of the sliding plate 331 and is fixedly connected to the movable frame 32 by bolts. A protruding rod 332 is fixedly connected to the top of the sliding plate 331. A threaded limiting sleeve 333 is fitted on the outer wall of the protruding rod 332. The bottom of the limiting sleeve 333 abuts against the top of the guide frame 33. Both the bottom of the limiting sleeve 333 and the top of the guide frame 33 are provided with anti-slip protrusions to increase the friction when they abut against each other.

[0029] It should be noted that: by inserting a sliding plate 331 inside the guide frame 33, when installing this device, after connecting the mounting frame 31 to the side wall at the top of the waste liquid treatment tank, the sliding plate 331 can be moved as needed to slide, thereby adjusting the position of the bottom docking block of the sliding plate 331, so that the docking block can be smoothly moved to the frame 32 for docking and fixing.

[0030] Then the limiting sleeve 333 can be twisted so that the bottom of the limiting sleeve 333 abuts against the top of the guide frame 33, thereby increasing the friction between the sliding plate 331 and the guide frame 33, which in turn allows the fixed frame to stably support the mounting frame 4, the storage cylinder 1 and the dosing component 2, so that they can be stably erected between the two mounting frames 31, thus making the installation and assembly of this device more flexible and convenient.

[0031] Furthermore, during the feeding process, the rotation of the screw can drive the storage cylinder 1 and the dosing component 2 to move horizontally inside the waste liquid treatment tank, thereby allowing the flocculant added by the dosing component 2 to diffuse and react more evenly inside the treatment tank.

[0032] Meanwhile, by installing a lead screw protective sleeve (not shown in the figure), the lead screw protective sleeve can protect the outside of the drive lead screw 311, thereby reducing the phenomenon of external particulate impurities falling on the exposed drive lead screw 311 and causing jamming on its later movement of the moving frame 32.

[0033] In the embodiments of this utility model, please refer to Figures 1 to 4 The storage cylinder 1 is provided with a fixedly connected mounting frame 4. Both ends of the mounting frame 4 are fixedly connected to the corresponding guide frame 33. A fixedly connected pump body 41 is installed on the mounting frame 4. The input end of the pump body 41 is connected to the bottom of the storage cylinder 1. The output end of the pump body 41 is fixedly installed with a connected adapter pipe 42. A connected flexible hose 24 is provided between the adapter pipe 42 and the fixedly installed guide pipe 22.

[0034] It should be noted that by using a connecting hose 24 to connect the feed pipe 22 and the transfer pipe 42, during use, when the hydraulic rod 211 extends to drive the lower dosing component 2 to reciprocate vertically, the connecting hose 24 can move synchronously, thus making the movement of the dosing component 2 smoother.

[0035] The working principle of the drilling fluid flocculant feeding device provided by this utility model is as follows:

[0036] When using this device, the mounting bracket 31 in the mounting assembly 3 can be fixedly mounted on the side wall of the treatment pool for the drilling fluid waste to be treated. Then, the sliding plate 331 can be controlled to slide inside the guide frame 33 as needed, so that the mounting frame 4 and the top treatment cylinder can be mounted between the mounting brackets 31 on both sides. Then, the limiting sleeve 333 can be controlled to rotate until the bottom end of the limiting sleeve 333 abuts against the top of the guide frame 33, thereby fixing the sliding plate 331.

[0037] Next, according to the required corresponding feed pipe 22, multiple feed pipes 22 can be connected and fixed by bolts. At the same time, the connecting hose 24 can be taken out and the feed pipe 22 can be connected to the transfer pipe 42 to complete the installation of this device. Then, the required flocculant can be added into the storage cylinder 1 and the pump body 41 can be controlled to work. The working pump body 41 can transport the flocculant in the storage cylinder 1 to the feed pipe 22 through the connecting hose 24.

[0038] The flocculant entering the feed pipe 22 can be smoothly discharged outward through the dosing pipe 221 connected to it. During this process, the hydraulic cylinder can be controlled to extend and retract, and the drive screw 311 can be controlled to rotate. The extending hydraulic cylinder can drive the feed pipe 22 and the dosing pipe 221 connected to it to move back and forth in the vertical direction through the support frame 21. The rotating drive screw 311 can drive the storage cylinder 1 and the dosing component 2 to move in the horizontal direction through the sliding plate 331 via the threaded structure, so that the dosing component 2 can move up and down in the horizontal direction inside the treatment tank.

[0039] Furthermore, during this process, when the stirring paddle 231 on the outer wall of the feed pipe 22 comes into contact with the waste liquid, the resistance generated by the contact can smoothly drive the stirring paddle 231 to rotate, thereby stirring and mixing the waste liquid at the flocculant discharge point, thus making the diffusion and mixing of the flocculant in the waste liquid more uniform.

[0040] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0041] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
