Description

Technical Field

[0001] This invention relates to a dredging device, specifically, to a tool for dredging pipelines at sampling and measuring points. It also relates to a chemical system. Background Technology

[0002] Chemical production requires various instruments for measurement and control. Based on the processes and material properties of chemical products, some materials exhibit characteristics such as cold solidification at low temperatures, hot melting at high temperatures, and high-temperature oxygen leakage leading to coking and carbonization. This coking and carbonization can clog sampling and measuring points. When the pipelines at these sampling and measuring points are obstructed or blocked, it can cause deviations in the measurement of reaction parameters during production, resulting in false readings. Severe deviations in reaction parameter measurements can trigger protective devices, causing interruptions in continuous production and resulting in significant losses.

[0003] Therefore, it is essential to regularly inspect and clean the sampling points to ensure their unobstructed flow. Currently, the method used to unclog the sampling points is manual, using a needle. However, this process poses safety hazards that could cause personal injury, and there is also the issue of difficult-to-remove coked material during the unblocking process. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a sampling point pipeline unblocking tool, which can effectively unblock the sampling point and eliminate safety hazards, and has high safety.

[0005] Another technical problem that this invention aims to solve is to provide a chemical system that can effectively ensure the smooth operation of sampling and measurement points in the reactor.

[0006] To address the aforementioned technical problems, this invention provides a sampling and measuring point pipeline unblocking tool, comprising a needle drill bit, a moving platform, a drill bit drive mechanism for driving the needle drill bit to rotate, a moving mechanism for driving the moving platform to move along the axial direction of the needle drill bit, and an anti-splash shield for blocking fluid material ejection from the sampling and measuring point pipeline. The needle drill bit and the drill bit drive mechanism are both mounted on the moving platform, and the anti-splash shield is fitted onto the needle drill bit through a drill bit mounting hole in its middle. Multiple material splash-proof grooves are formed on the spray-bearing surface of the anti-splash shield, spaced apart around the drill bit mounting hole. These multiple material splash-proof grooves are interconnected by connecting grooves. Each material splash-proof groove has a central protruding guide baffle extending along the groove and with a protrusion height lower than the groove depth. Each of these central protruding guide baffles is inclined towards the drill bit mounting hole.

[0007] In some embodiments, the plurality of material splash guards are grooves arranged in concentric circles around the drill bit mounting hole, and each of the central protruding guide partitions has a through hole.

[0008] In some embodiments, the anti-jet shield is provided with a stuffing box on the side facing the mobile platform, the stuffing box containing packing material capable of preventing the fluid material from leaking out along the axial direction of the needle drill bit.

[0009] In some embodiments, a gland for axial compression of the packing is installed on the stuffing box.

[0010] In some embodiments, the moving mechanism includes a guiding mechanism, a transmission mechanism, and a moving platform driving mechanism. The moving platform is connected to the guiding mechanism, and the moving platform driving mechanism is connected to the moving platform through the transmission mechanism to drive the moving platform to move along the axial direction of the needle drill bit under the guidance of the guiding mechanism.

[0011] In some embodiments, the guiding mechanism is a rolling linear guide.

[0012] In some embodiments, the transmission mechanism is a ball screw.

[0013] In some embodiments, the mobile platform drive mechanism is a servo motor.

[0014] In some embodiments, the transmission mechanism and the moving platform drive mechanism are connected by a coupling.

[0015] Another aspect of the present invention provides a chemical system, including a reactor and a sampling and measuring point pipeline unblocking tool as described in any of the above technical solutions. A pneumatic ball valve is provided on the sampling and measuring point pipeline of the reactor, and the axis of the needle drill extends along the axial direction of the sampling and measuring point pipeline so as to be able to extend into the sampling and measuring point pipeline.

[0016] In some embodiments, a control system is also included, which is communicatively connected to the drill bit drive mechanism, the moving mechanism, and the pneumatic ball valve, respectively.

[0017] The beneficial effects of the present invention through the above technical solution are as follows:

[0018] A mobile platform driven by a moving mechanism aligns the needle drill bit with the sampling point on the pressure tap of the reactor. The drill bit drive mechanism rotates the needle drill bit to clean the coking material, achieving automated cleaning. Furthermore, because the needle drill bit is equipped with an anti-spray shield, it eliminates the personal injury associated with manual needle cleaning. Additionally, a material splash guard is installed on the spray-bearing surface of the anti-spray shield, with a centrally protruding guide baffle inside. This prevents fluid from overflowing along the spray-bearing surface of the anti-spray shield and causing injury to personnel passing below or damage to surrounding equipment, thus eliminating safety hazards.

[0043] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0044] like Figure 1 and Figure 2 As shown, this invention provides a tool for unblocking sampling and measuring point pipelines, including a needle drill bit 1, a moving platform 2, a drill bit drive mechanism 3, and a moving mechanism. The drill bit drive mechanism 3 drives the needle drill bit 1 to rotate, and the moving mechanism drives the moving platform 2 to move along the axial direction of the needle drill bit 1. Both the needle drill bit 1 and the drill bit drive mechanism 3 are mounted on the moving platform 2, and the needle drill bit 1 is fitted with an anti-jet shield 4 to prevent the jetting of fluid materials during unblocking of the sampling and measuring point. Figure 5 and Figure 6 As shown, the anti-spray shield 4 is fitted onto the through-hole drill bit 1 through the drill bit mounting hole 44 in its middle. Multiple material splash guards 71 ​​are formed on the spray-bearing surface 45 of the anti-spray shield 4, which are distributed at intervals around the drill bit mounting hole 44. The multiple material splash guards 71 ​​are interconnected by the connecting grooves 72. Each material splash guard 71 has a middle protruding guide partition 73 that extends along the material splash guard 71 and whose protrusion height is lower than the groove depth. Each middle protruding guide partition 73 is inclined toward the drill bit mounting hole 44.

[0045] It should be noted that "sampling test point" refers to the sampling test port, sampling test point, and sampling test port of various chemical equipment and chemical instruments. The sampling test point pipeline unblocking tool of this invention is applicable to the unblocking of sampling test ports, sampling test points, and sampling test ports of various chemical equipment and chemical instruments. The sampling test point pipeline refers to the pipeline at the sampling test point. This invention uses a needle drill bit 1 to clean the coking material in the sampling test point pipeline, thereby unblocking the sampling test point pipeline.

[0046] To facilitate understanding of the technical solution of the present invention, the following is combined with... Figure 4 The usage status of the sampling and measuring point pipeline unblocking tools is explained. For example, in Figure 4In the illustrated embodiment, the chemical system includes a reactor 6, to which a pressure-sensing pipe 61 is connected. The pressure-sensing pipe 61 serves as an example of a sampling and testing pipeline, forming a sampling point. Reaction parameters during the production process are measured through the pressure-sensing pipe 61. This invention uses a moving mechanism to drive the moving platform 2 along the axial direction of the needle drill bit 1, thereby continuously extending the needle drill bit 1 into the pressure-sensing pipe 61 along its port. The drill bit drive mechanism 3 then drives the needle drill bit 1 to rotate, breaking up and cleaning the coking material inside the pressure-sensing pipe 61. Compared to existing manual methods of cleaning coking material, this method offers higher automation and facilitates the cleaning of coking material. Generally, before unblocking, the anti-jet shield 4 needs to be fixed to the structure of the pressure-sensing pipe 61 port. During the unblocking process, if the existing manual method of cleaning coking materials is used, there is a safety hazard of personal injury. This invention uses an anti-spray shield 4, which is fitted onto the needle drill bit 1 through the drill bit mounting hole 44 in its middle. This effectively prevents fluid material from spraying out during the unblocking and sampling testing points, eliminating the safety hazard of personal injury. Furthermore, it prevents damage to corresponding components or equipment due to high-temperature material spray. In addition, as... Figure 5 and Figure 6As shown, the side of the anti-splash shield 4 facing the pressure pipe 61 is the splash-bearing surface 45. Multiple material splash-proof grooves 71 are formed on the splash-bearing surface 45, spaced out from the inside around the drill bit mounting hole 44. Adjacent material splash-proof grooves 71 are interconnected by a connecting groove 72. A centrally protruding guide baffle 73 is provided within each material splash-proof groove 71. The centrally protruding guide baffle 73 extends along the material splash-proof groove 71, and its protrusion height is less than the groove depth. That is, the height of the centrally protruding guide baffle 73 protruding from the bottom surface of the material splash-proof groove 71 is less than the groove depth. Each centrally protruding guide baffle 73 is inclined towards the drill bit mounting hole 44. Thus, after the fluid material is ejected, it is first blocked by the splash-bearing surface 45 of the anti-splash shield 4 and will not continue to eject outwards axially. The ejected fluid material will overflow downwards along the splash-bearing surface 45. The presence of the material splash guard 71 allows fluid materials to flow into it. If the fluid material is splashed into the space between the protruding guide baffle 73 and the outer wall of the material splash guard 71, the protrusion height of the protruding guide baffle 73 is lower than the depth of the material splash guard 71, and the protruding guide baffles 73 are all inclined towards the drill bit mounting hole 44. The fluid material can flow along the outer side of the protruding guide baffle 73 and around its end to the space between the protruding guide baffle 73 and the inner wall of the material splash guard 71. Moreover, the material splash guards 71 ​​are interconnected through the connecting groove 72, which can disperse the fluid material in the material splash guard 71 and prevent the fluid material from accumulating in one or more material splash guards 71, thereby avoiding excessive accumulation of fluid material in one or more material splash guards 71 ​​and causing overflow. Among them, pressure tapping pipe 61 refers to the pressure tapping pipe of a reactor that requires pressure measurement in chemical production.

[0047] Furthermore, such as Figure 5 As shown, multiple material splash guards 71 ​​are concentrically spaced around the drill bit mounting hole 44, and each of the central protruding guide baffles 73 has a through hole 74. After the fluid material is sprayed, if the fluid material is splashed into the space between the central protruding guide baffle 73 and the outer wall of the material splash guard 71, due to the through hole 74 formed on the central protruding guide baffle 73, some of the fluid material can flow through the through hole 74 into the space between the central protruding guide baffle 73 and the inner wall of the material splash guard 71.

[0048] In some embodiments, the drill bit drive mechanism 3 can be a servo motor, and the drill bit drive mechanism 3 is connected to the shaft of the needle drill bit 1 via a coupling. The needle drill bit 1 can be in the form of a twist drill, which can efficiently clear coked materials.

[0049] In a specific embodiment, such as Figure 2 As shown, the moving mechanism includes a guide mechanism 51, a transmission mechanism 52, and a moving platform drive mechanism 53. The moving platform 2 is connected to the guide mechanism 51, and the moving platform drive mechanism 53 is connected to the moving platform 2 through the transmission mechanism 52. Under the action of the transmission mechanism 52, the moving platform 2 can be driven to move along the axis of the needle drill bit 1 under the guidance of the guide mechanism 51, thereby allowing the needle drill bit 1 to be inserted into the pressure tube 61.

[0050] Furthermore, the guide mechanism 51 can be a rolling linear guide, which includes a slider and a slide rail. Several steel balls are arranged on the slider and slide rail, rolling in an infinite cycle, allowing the moving platform 2 to perform high-precision linear movement along the slide rail. Generally, the moving platform 2 is connected to the slider, and the slide rail is laid on the mounting plate, with the slide rail's laying direction consistent with the axial direction of the needle drill bit 1, thereby controlling the movement of the needle drill bit 1 along its axial direction. Alternatively, the guide mechanism 51 can also be other types of linear guides. For example, the guide mechanism 51 includes a slider and a slide rail, with a groove on the slide rail. The moving platform 2 is connected to the slider, and the slider cooperates with the groove on the slide rail to guide the moving platform 2. As another example, the guide mechanism 51 includes a slider and a slide rail, with the moving platform 2 connected to the slider. A pulley is arranged on the slider, and the pulley cooperates with the slide rail to guide the moving platform 2.

[0051] In a specific embodiment, the transmission mechanism 52 can be a ball screw, which includes a screw and a nut. The screw is connected to the moving platform drive mechanism 53, and the nut is connected to the moving platform 2, so as to drive the moving platform 2 to move along the axial direction of the needle drill bit 1.

[0052] In a specific embodiment, the mobile platform drive mechanism 53 can be a servo motor. The mobile platform drive mechanism 53 is connected to the transmission mechanism 52 through a coupling 54. Specifically, the mobile platform drive mechanism 53 is connected to the screw of the ball screw through a coupling 54.

[0053] To further prevent the leakage of high-temperature materials, such as Figure 3As shown, a stuffing box 41 is provided on the side of the anti-jet shield 4 facing away from the sampling point, that is, the stuffing box 41 is provided on the side of the anti-jet shield 4 facing the moving platform 2. The stuffing box 41 contains a packing 42, which can prevent high-temperature materials from leaking out along the axial direction of the needle drill bit 1. Further, a pressure cap 43 is installed on the stuffing box 41. When the screw on the pressure cap 43 is tightened, the pressure cap 43 can axially compress the packing 42. Specifically, the packing 42 can be a molded packing. After the packing 42 is installed into the packing cavity of the stuffing box 41, the screw on the pressure cap 43 axially compresses the packing 42. When there is relative movement between the shaft of the needle drill bit 1 and the packing 42, due to the plasticity of the packing 42, the packing 42 generates a radial force and comes into close contact with the shaft of the needle drill bit 1. At the same time, the lubricant impregnated in the packing 42 is squeezed out, forming an oil film between the contact surfaces. Because the contact state is not particularly uniform, there are contact areas and non-contact areas between the two. The contact areas exhibit boundary lubrication, known as the "bearing effect." The recesses of the non-contact areas form small oil grooves with a thicker oil film. The contact areas and non-contact areas form an irregular labyrinth, which helps to prevent fluid leakage. This is called the "labyrinth effect."

[0054] To better understand the technical concept of this invention, the following description is provided in conjunction with a relatively comprehensive set of technical features.

[0055] like Figures 1 to 3As shown, a preferred embodiment of the present invention provides a sampling and measuring point pipeline unblocking tool, including a needle drill bit 1, a moving platform 2, a drill bit drive mechanism 3, and a moving mechanism. The moving mechanism includes a guide mechanism 51, a transmission mechanism 52, and a moving platform drive mechanism 53. The guide mechanism 51 can be a rolling linear guide, the transmission mechanism 52 can be a ball screw, and the drill bit drive mechanism 3 and the moving platform drive mechanism 53 can be servo motors. The moving platform drive mechanism 53 is connected to the transmission mechanism 52 through a coupling 54. The guide mechanism 51 is connected to the moving platform 2 and is used to guide the moving platform 2. The transmission mechanism 52 is connected to the moving platform 2 and is used to transmit the driving force of the moving platform drive mechanism 53 to drive the moving platform 2 to move. Both the needle drill bit 1 and the drill drive mechanism 3 are mounted on the mobile platform 2. The drill drive mechanism 3 is connected to the shaft of the needle drill bit 1 via a coupling, and is used to drive the needle drill bit 1 to rotate. Compared with the existing manual needle cleaning method, this invention uses a servo motor to drive the needle drill bit 1. For relatively hard coking materials, it can effectively clear the coking material, save manpower, reduce labor intensity, and efficiently clear coking materials. The needle drill bit 1 is fitted with an anti-jet shield 4. A stuffing box 41 is set on the side of the anti-jet shield 4 facing the mobile platform 2. The stuffing box 41 contains packing 42, which can prevent high-temperature materials from leaking out along the axial direction of the needle drill bit 1. A pressure cap 43 is installed on the stuffing box 41. When the screws on the pressure cap 43 are tightened, the pressure cap 43 can axially compress the packing 42, which has a high safety performance during clearing and can effectively prevent safety accidents caused by material ejection.

[0056] The side of the anti-spray shield 4 facing away from the moving platform 2 is the spray-bearing surface 45, and the spray-bearing surface 45 of the anti-spray shield 4 is tightly fitted to the flange at the interface of the reactor 6. Generally, workers may pass under the reactor 6. Therefore, if the ejected fluid material overflows downward along the spray-bearing surface 45, there is a possibility of injury to workers passing below. Therefore, multiple material splash guards 71 ​​are formed on the spray-bearing surface 45. Each material splash guard 71 is distributed from the inside to the outside around the drill bit mounting hole 44. Adjacent material splash guards 71 ​​are interconnected by a connecting groove 72. A centrally protruding guide baffle 73 is provided in the material splash guard 71. The centrally protruding guide baffle 73 extends along the material splash guard 71, and the protrusion height of the centrally protruding guide baffle 73 is less than the groove depth. Each centrally protruding guide baffle 73 is inclined towards the drill bit mounting hole 44, and a connecting through hole 74 is formed on each centrally protruding guide baffle 73. After the fluid material is ejected, it is first blocked by the ejection-bearing surface 45 of the ejection shield 4, preventing it from continuing to spray outward axially. The ejected fluid material overflows downward along the ejection-bearing surface 45. Due to the presence of the material splash guard 71, the fluid material can flow into the material splash guard 71. If the fluid material is splashed into the space between the middle protruding guide baffle 73 and the outer wall of the material splash guard 71, since the protrusion height of the middle protruding guide baffle 73 is lower than the depth of the material splash guard 71, and the middle protruding guide baffles 73 are all inclined towards the drill bit mounting hole 44, some of the fluid material can flow along the middle protruding guide baffle 73. The fluid flows from the outer side of the 3 and around the end of the protruding guide partition 73 to the space between the protruding guide partition 73 and the inner wall of the material splash guard 71. Some fluid material can flow through the connecting hole 74 to the space between the protruding guide partition 73 and the inner wall of the material splash guard 71. The material splash guards 71 ​​are interconnected by the connecting groove 72, which can disperse the fluid material in the material splash guard 71 and prevent the fluid material from accumulating in a certain material splash guard 71 or some material splash guards 71, thereby avoiding the overflow of excessive fluid material accumulating in a certain material splash guard 71 or some material splash guards 71.

[0057] like Figure 4 As shown, this embodiment of the invention also provides a chemical system, including a reactor 6. A pneumatic ball valve 62 is installed on the sampling point pipeline of the reactor 6. The axis of the needle drill 1 extends along the axis of the sampling point pipeline so as to be able to extend into the sampling point pipeline. Specifically, the sampling point pipeline can be a pressure tapping pipe 61. During unblocking, the needle drill 1 is driven by the moving mechanism to extend into the pressure tapping pipe 61 and fastens the anti-jet shield 4 to the flange at the interface of the pressure tapping pipe 61. The anti-jet shield 4 can be a flange.

[0058] Furthermore, the chemical system of the present invention also includes a control system, which is communicatively connected to the drill bit drive mechanism 3, the moving mechanism, and the pneumatic ball valve 62. Specifically, the control system can be a DCS (Distributed Control System). This enables online remote control; operators only need to be in the control room to clear the sampling points via the DCS system. Throughout the process, operators do not need to be physically present on-site, avoiding the need for operators to work at heights and ensuring their personal safety.

[0059] like Figure 4 As shown, the sampling and measuring point pipeline unblocking tool of the present invention is fixed near the reactor 6 by the mounting plate, and the needle drill bit 1 is inserted into the interface of the pressure pipe 61. It is then fastened to the flange at the end of the pressure pipe 61 by the anti-jet shield 4. During the cleaning of coking material, the operator in the control room issues control commands through the DCS system to open the pneumatic ball valve 62, and then controls the moving platform drive mechanism 53 to drive the moving platform 2 to move. The moving platform 2 drives the needle drill bit 1 to move along the axial direction of the needle drill bit 1, continuously extending into the pressure pipe 61. The drill bit drive mechanism 3 is controlled to drive the needle drill bit 1 to rotate, cleaning the coking material in the pressure pipe 61. In this process, the coking material is typically located between the interface of the pressure-inlet pipe 61 and the pneumatic ball valve 62. When cleaning the coking material, the needle drill 1 is usually inserted beyond the position of the pneumatic ball valve 62. Furthermore, by installing an anti-jet shield 4, fluid material is prevented from being ejected outwards along the pressure-inlet pipe 61 after the needle drill 1 has cleaned the coking material. After clearing the blockage, the pneumatic ball valve 62 is closed. After clearing the pressure-inlet pipe 61, it is connected to a reaction parameter detection device, or the reaction parameters within the reactor 6 are measured using a reaction parameter detection device already installed on the pressure-inlet pipe 61. This reaction parameter detection device can be a pressure sensor for detecting pressure, a temperature sensor for detecting temperature, etc.

[0060] The sampling and measuring point pipeline unblocking tool of the present invention is also characterized by its simplicity of use and ease of installation.

[0061] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0062] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately.

[0063] Furthermore, various different embodiments of the present invention can be combined in any way, as long as they do not violate the spirit of the present invention, they should also be regarded as the content disclosed by the present invention.
