[0044] like Figure 1 and Figure 2 As shown, the present invention provides a sampling point pipeline dredging tool, including a needle drill bit 1, a mobile platform 2, a drill bit driving mechanism 3 and a mobile mechanism, the drill bit driving mechanism 3 is used to drive the needle drill bit 1 to rotate, the mobile mechanism is used to drive the mobile platform 2 to move along the axis direction of the needle drill bit 1, the needle drill bit 1 and the drill bit driving mechanism 3 are both installed on the mobile platform 2, and the needle drill bit 1 is equipped with an anti-spray shielding member 4, the anti-spray shielding member 4 is used to prevent the spray of fluid materials when dredging the sampling point. Figure 5 and Figure 6 As shown, the anti-spray shield 4 is mounted on the needle drill 1 through the drill mounting hole 44 in the middle thereof, and a plurality of material splash-proof grooves 71 are formed on the spray-bearing surface 45 of the anti-spray shield 4 around the drill mounting hole 44 and spaced apart. The plurality of material splash-proof grooves 71 are interconnected through connecting grooves 72, and each of the material splash-proof grooves 71 is provided with an intermediate protruding guide baffle 73 extending along the material splash-proof groove 71 and having a protruding height lower than the groove depth, and each intermediate protruding guide baffle 73 is inclined toward the drill mounting hole 44.

[0045] It should be noted that "sampling point" refers to the sampling test ports, sampling test points, sampling test ports, and sampling test points of various chemical devices and chemical instruments. The sampling test point pipeline dredging tool of the present invention is suitable for dredging the sampling test ports, sampling test points, sampling test ports, and sampling test points of various chemical devices and chemical instruments. The sampling test point pipeline refers to the pipeline at the sampling test point. The present invention cleans the coking material in the sampling test point pipeline by using the needle drill bit 1 to achieve the dredging of the sampling test point pipeline.

[0046] In order to facilitate the understanding of the technical solution of the present invention, the following Figure 4 The following is an explanation of the usage of the sampling point pipeline dredging tool. Figure 4In the illustrated embodiment, the chemical system includes a reactor 6, to which a pressure-drawing pipe 61 is connected. The pressure-drawing pipe 61 is used as an example of a sampling test pipeline to form a sampling measurement point. The reaction parameters in the production process are measured through the pressure-drawing pipe 61. The present invention drives the mobile platform 2 along the axial direction of the needle drill bit 1 through a moving mechanism, and then the needle drill bit 1 is continuously extended into the pressure-drawing pipe 61 along the port of the pressure-drawing pipe 61, and then the needle drill bit 1 is driven to rotate through the drill bit driving mechanism 3 to crush and clean the coked materials in the pressure-drawing pipe 61. Compared with the existing manual cleaning method of coked materials, it has higher automation and is convenient for cleaning coked materials. Generally, before dredging, the anti-injection shielding member 4 and the structure of the port of the pressure-drawing pipe 61 need to be fixed. During the dredging process, if the existing manual method of cleaning the coking material is adopted, there is a safety hazard of causing harm to people. The present invention enables the anti-spray shielding member 4 to be mounted on the needle drill bit 1 through the drill bit mounting hole 44 in the middle thereof, which can effectively prevent the fluid material from being sprayed when the sampling point is dredged, eliminates the safety hazard of causing harm to people, and will not cause the corresponding components or equipment to be damaged due to the high-temperature material spray. In addition, if Figure 5 and Figure 6As shown, one side of the anti-splash shield 4 facing the pressure-guiding pipe 61 is an injection bearing surface 45, and a plurality of material splash-proof grooves 71 are formed on the injection bearing surface 45, and each material splash-proof groove 71 is spaced from the inside to the outside around the drill bit mounting hole 44, and adjacent material splash-proof grooves 71 are connected to each other through connecting grooves 72, and an intermediate protruding guide partition 73 is arranged in the material splash-proof groove 71, and the intermediate protruding guide partition 73 extends along the material splash-proof groove 71, and the protruding height of the intermediate protruding guide partition 73 is lower than the groove depth, that is, the intermediate protruding guide partition 73 protrudes from the bottom surface of the material splash-proof groove 71 higher than less than the groove depth of the material splash-proof groove 71, and each intermediate protruding guide partition 73 is inclined toward the drill bit mounting hole 44, so that after the fluid material is sprayed, the fluid material is first blocked by the injection bearing surface 45 of the anti-splash shield 4, and will not continue to spray outward along the axial direction, and the sprayed fluid material will overflow downward along the injection bearing surface 45, and will be sprayed out by the Due to the existence of the material anti-splash groove 71, the fluid material can flow into the material anti-splash groove 71. If the fluid material is splashed into the space between the middle protruding guide partition 73 and the outer side wall of the material anti-splash groove 71, since the protruding height of the middle protruding guide partition 73 is lower than the groove depth of the material anti-splash groove 71, and the middle protruding guide partition 73 is inclined toward the drill bit mounting hole 44, the fluid material can flow along the outer side surface of the middle protruding guide partition 73 and bypass the end of the middle protruding guide partition 73 to the space between the middle protruding guide partition 73 and the inner side wall of the material anti-splash groove 71. Moreover, the material anti-splash grooves 71 are connected to each other through the connecting grooves 72, which can disperse the fluid material in the material anti-splash grooves 71 to prevent the fluid material from accumulating in a certain material anti-splash groove 71 or in some material anti-splash grooves 71, thereby avoiding excessive accumulation of fluid material in a certain material anti-splash groove 71 or in some material anti-splash grooves 71 and overflowing. The pressure-leading pipe 61 refers to a pressure-taking outlet pipe of a reactor that needs to measure pressure in chemical production.

[0047] Furthermore, if Figure 5 As shown, multiple material splash-proof grooves 71 are grooves distributed in concentric circles around the drill bit mounting hole 44, and each intermediate protruding guide baffle 73 is formed with a connecting hole 74. After the fluid material is sprayed, if the fluid material is splashed into the space between the intermediate protruding guide baffle 73 and the outer wall of the material splash-proof groove 71, since the connecting hole 74 is formed on the intermediate protruding guide baffle 73, part of the fluid material can flow through the connecting hole 74 to the space between the intermediate protruding guide baffle 73 and the inner wall of the material splash-proof groove 71.

[0048] In some embodiments, the drill driving mechanism 3 may be a servo motor, and the drill driving mechanism 3 is connected to the shaft of the needle drill 1 through a coupling. The needle drill 1 may be in the form of a twist drill, and can efficiently clear the coked material.

[0049] In a specific embodiment, Figure 2 As shown, the moving mechanism includes a guide mechanism 51, a transmission mechanism 52 and a mobile platform driving mechanism 53. The mobile platform 2 is connected to the guide mechanism 51. The mobile platform driving mechanism 53 is connected to the mobile platform 2 through the transmission mechanism 52. Under the action of the transmission mechanism 52, the mobile platform 2 can be driven to move along the axial direction of the needle drill bit 1 under the guidance of the guide mechanism 51, thereby inserting the needle drill bit 1 into the pressure-inducing tube 61.

[0050] Furthermore, the guide mechanism 51 can be a rolling linear guide rail, which includes a slider and a slide rail, and a plurality of steel balls are arranged on the slider and the slide rail to perform an infinite rolling cycle, so that the mobile platform 2 can perform linear motion along the slide rail with high precision. Generally, the mobile platform 2 is connected to the slider, and the slide rail is laid on the mounting plate, so that the laying direction of the slide rail is consistent with the axial direction of the needle drill bit 1, so that the needle drill bit 1 can be controlled to move along its axial direction. Alternatively, the guide mechanism 51 can also be other types of linear guide rails, for example, the guide mechanism 51 includes a slider and a slide rail, a slide groove is arranged on the slide rail, the mobile platform 2 is connected to the slider, and the slider cooperates with the slide groove on the slide rail to achieve the guiding effect on the mobile platform 2. For another example, the guide mechanism 51 includes a slider and a slide rail, the mobile platform 2 is connected to the slider, a pulley is arranged on the slider, and the pulley cooperates with the slide rail to achieve the guiding effect on the mobile 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 mobile platform driving mechanism 53, and the nut is connected to the mobile platform 2 so as to drive the mobile platform 2 to move along the axial direction of the needle drill bit 1.

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

[0053] In order 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-injection shield 4 facing away from the sampling point, that is, a stuffing box 41 is provided on the side of the anti-injection shield 4 facing the mobile platform 2, and a stuffing box 42 is built in the stuffing box 41, and the stuffing box 42 can prevent the high-temperature material from leaking along the axial direction of the needle drill 1. Further, a pressure cap 43 is installed on the stuffing box 41, and when the screws on the pressure cap 43 are tightened, the pressure cap 43 can axially compress the stuffing 42. Specifically, the stuffing 42 can be a molded stuffing. After the stuffing 42 is loaded into the stuffing cavity of the stuffing box 41, the stuffing 42 is axially compressed by the screws on the pressure cap 43. When there is relative movement between the shaft of the needle drill 1 and the stuffing 42, due to the plasticity of the stuffing 42, the stuffing 42 generates a radial force and is in close contact with the shaft of the needle drill 1. At the same time, the lubricant impregnated in the stuffing 42 is squeezed out, and an oil film is formed between the contact surfaces between the two. Since the contact state is not particularly uniform, there are contact parts and non-contact parts between the two. The contact part between the two shows boundary lubrication, which is called the "bearing effect"; and the concave part of the non-contact part between the two forms a small oil groove with a thicker oil film. The contact part and the non-contact part form an irregular maze, which prevents liquid leakage. This is called the "maze effect".

[0054] In order to better understand the technical concept of the present invention, a relatively comprehensive description is given below in combination with the 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 mobile platform 2, a drill bit driving mechanism 3 and a mobile mechanism, the mobile mechanism including a guide mechanism 51, a transmission mechanism 52 and a mobile platform driving mechanism 53, the guide mechanism 51 can be a rolling linear guide, the transmission mechanism 52 can be a ball screw, the drill bit driving mechanism 3 and the mobile platform driving mechanism 53 can be servo motors, the mobile platform driving mechanism 53 is connected to the transmission mechanism 52 through a coupling 54, the guide mechanism 51 is connected to the mobile platform 2 for guiding the mobile platform 2, the transmission mechanism 52 is connected to the mobile platform 2 for transmitting the driving force of the mobile platform driving mechanism 53 to drive the mobile platform 2 to move. The needle drill bit 1 and the drill driving mechanism 3 are both installed on the mobile platform 2. The drill driving mechanism 3 is connected to the shaft of the needle drill bit 1 through a coupling, and is used to drive the needle drill bit 1 to rotate. Compared with the existing manual needle cleaning method, the present invention adopts a servo motor to drive the needle drill bit 1. For relatively solid coking materials, it can play a good dredging function for the coked materials, save manpower, reduce work intensity, and can efficiently dredge the coked materials. The needle drill bit 1 is equipped with an anti-injection shielding member 4. The anti-injection shielding member 4 is provided on the side of the mobile platform 2. The stuffing box 41 has a stuffing 42 built in it. The stuffing 42 can prevent the high-temperature material from leaking along the axial direction of the needle drill bit 1. The stuffing box 41 is installed with a pressure cap 43. When the screws on the pressure cap 43 are tightened, the pressure cap 43 can axially compress the stuffing 42. The safety performance is high during dredging, and it can effectively prevent safety accidents caused by material spraying.

[0056] The side of the anti-spray shield 4 facing away from the mobile platform 2 is the spray bearing surface 45, and the spray bearing surface 45 of the anti-spray shield 4 is fitted and fastened with the flange at the interface of the reactor 6. Generally, the staff may pass under the reactor 6, so if the fluid material sprayed out will overflow downward along the spray bearing surface 45, there is a possibility of causing harm to the staff passing below. Therefore, a plurality of material splash-proof grooves 71 are formed on the spray-proof bearing surface 45, each material splash-proof groove 71 is spaced from the inside to the outside around the drill bit mounting hole 44, and the adjacent material splash-proof grooves 71 are connected to each other through the connecting groove 72, and an intermediate protruding guide partition 73 is arranged in the material splash-proof groove 71, and the intermediate protruding guide partition 73 extends along the material splash-proof groove 71, and the protruding height of the intermediate protruding guide partition 73 is lower than the groove depth, and each intermediate protruding guide partition 73 is inclined toward the drill bit mounting hole 44, and each intermediate protruding guide partition 73 is formed with a connecting through hole 74. After the fluid material is sprayed, the fluid material is first blocked by the spray receiving surface 45 of the anti-spray shielding member 4 and will not continue to spray outward along the axial direction. The sprayed fluid material will overflow downward along the spray receiving surface 45. Due to the existence of the material splash-proof groove 71, the fluid material can flow into the material splash-proof groove 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-proof groove 71, since the protruding height of the middle protruding guide baffle 73 is lower than the groove depth of the material splash-proof groove 71, and the middle protruding guide baffle 73 is inclined toward the drill bit mounting hole 44, part of the fluid material can flow along the middle protruding guide baffle 73. 3 and bypass the end of the middle protruding guide baffle 73 to flow into the space between the middle protruding guide baffle 73 and the inner wall of the material splash-proof groove 71, and part of the fluid material can flow into the space between the middle protruding guide baffle 73 and the inner wall of the material splash-proof groove 71 through the connecting hole 74. The material splash-proof grooves 71 are connected to each other through the connecting groove 72, which can disperse the fluid material in the material splash-proof groove 71, prevent the fluid material from accumulating in a certain material splash-proof groove 71 or in some material splash-proof grooves 71, and thus prevent the fluid material from accumulating too much in a certain material splash-proof groove 71 or in some material splash-proof grooves 71 and overflowing.

[0057] like Figure 4 As shown, an embodiment of the present invention further provides a chemical system, including a reactor 6, a pneumatic ball valve 62 is provided on the sampling and measuring point pipeline of the reactor 6, and the axis of the needle drill bit 1 extends along the axis direction of the sampling and measuring point pipeline so as to be able to extend into the sampling and measuring point pipeline. Specifically, the sampling and measuring point pipeline can be a pressure-conducting pipe 61. When dredging, the needle drill bit 1 is driven by the moving mechanism to extend into the pressure-conducting pipe 61, and the anti-spray shielding member 4 is fastened to the flange at the interface of the pressure-conducting pipe 61, and the anti-spray shielding member 4 can be a flange.

[0058] Furthermore, the chemical system of the present invention also includes a control system, which is respectively connected to the drill drive mechanism 3, the mobile mechanism and the pneumatic ball valve 62. Specifically, the control system can be a DCS (distributed control system) system. Online remote control can be achieved, and the operator only needs to be in the control room to dredge the sampling points through the DCS system. During the whole process, the operator does not need to be on site in person, which avoids the operator's high-altitude operation and ensures the operator's personal safety.

[0059] like Figure 4 As shown, the sampling and measuring point pipeline dredging tool of the present invention is fixed at a position near the reactor 6 through a mounting plate, and the needle drill bit 1 is inserted into the interface of the pressure-inducing pipe 61, and is fastened to the flange at the end of the pressure-inducing pipe 61 through the anti-injection shielding member 4. During the coking material cleaning process, the operator is in the control room, and issues a control instruction through the DCS system to control the pneumatic ball valve 62 to open, and then controls the mobile platform driving mechanism 53 to drive the mobile platform 2 to move, so that the mobile platform 2 drives the needle drill bit 1 to move along the axial direction of the needle drill bit 1, and continuously extends into the pressure-inducing pipe 61, and controls the drill bit driving mechanism 3 to drive the needle drill bit 1 to rotate, so as to clean the coking material in the pressure-inducing pipe 61. In which, the coking material is generally located between the interface of the pressure-inducing pipe 61 and the pneumatic ball valve 62. When the coking material is cleaned, the needle drill 1 usually drills beyond the position of the pneumatic ball valve 62. Moreover, by setting the anti-injection shielding member 4, after the needle drill 1 completes the cleaning of the coking material in the pressure-inducing pipe 61, the fluid material is prevented from being ejected outward along the pressure-inducing pipe 61. After the dredging is completed, the pneumatic ball valve 62 is closed. After the pressure-inducing pipe 61 is dredged, the pressure-inducing pipe 61 is connected to the reaction parameter detection device, or the reaction parameters in the reactor 6 are measured by the reaction parameter detection device installed on the pressure-inducing pipe 61, wherein the reaction parameter detection device can be a pressure sensor for detecting pressure, a temperature sensor for detecting temperature, and the like.

[0060] The sampling and measuring point pipeline dredging tool of the present invention is also simple to use and easy to install.

[0061] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.

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

[0063] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
