Description

Technical Field

[0001] The utility model relates to a special tool for clearing blockage in a process pipeline of titanium dioxide chloride production. Background Art

[0002] In the process of producing titanium tetrachloride, due to its high viscosity and the presence of a large amount of impurities such as vanadium and titanium, it is very easy to cause blockage in the titanium tetrachloride delivery pipeline. Due to the large diameter of the pipeline, the high hardness of the condensate, and the explosion-proof requirements of the working environment, high requirements are placed on the clearing equipment.

[0003] At present, there is no special equipment specifically used for clearing such pipes. When clearing pipes, simple tools such as manual or electric hammers are mostly used. The tools are not strong, large in size, heavy, and easy to damage. The labor intensity is high and it takes a long time. At the same time, when cleaning, the workers are at risk of being scalded or burned by the objects being cleaned. Therefore, it is considered to design a special unblocking tool to complete the cleaning of such pipes. Commonly used unblocking tools use a single excavation head or a single spiral structure. A single excavation head makes it impossible to discharge the excavated material immediately. When the hardness of the material is high, it is difficult to excavate with a single spiral structure. It is impossible to achieve automatic cleaning by relying on manpower to maintain the direction and strength of the unblocking. Utility Model Content

[0004] In order to reduce the difficulty and risk of unclogging a chloride process titanium dioxide conveying pipeline, the technical problem to be solved by the utility model is to provide a unclogging device for a chloride process titanium dioxide conveying pipeline.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a dredging device for chloride titanium dioxide conveying pipelines, including a support capable of realizing three-dimensional displacement adjustment and a pipeline dredging component installed on the support, the pipeline dredging component including a tunneling pipe component connected to a first driving device through a transmission device, the tunneling pipe component including a spiral pipe and a retractable central mandrel coaxially installed at the center of the spiral pipe, an adjustable tunneling head installed at the head of the central mandrel, and a cutter head with an adjustable effective diameter range installed on the adjustable tunneling head. By installing a cutter head with an adjustable effective diameter range, the inner cavity of the pipeline can be gradually cleaned from small to large, so as to protect the dredging component from excessive resistance and realize long-term normal operation of the machine. Through the support capable of three-dimensional displacement adjustment, the adjustable pipeline dredging component can be aligned with the pipeline to be cleaned and gradually penetrate into different depths of the pipeline for cleaning as the cleaning process progresses.

[0006] The adjustable boring head includes a conical head, a cutter head shell, and two or more cutter heads slidably mounted on the cutter head shell and arranged in a central symmetric manner. The conical head is connected to the end of the central mandrel, the bottom of the cutter head abuts against the conical head, the axis of the cutter head is perpendicular to the conical surface generatrix of the conical head, and the cutter head shell is fixed to the end of the spiral tube. The uniform installation of multiple cutter heads is achieved by the central mandrel and the conical head, and the telescopic adjustment is simultaneously beneficial to uniform force and improved cleaning speed.

[0007] The spiral tube includes a spiral shaft 1 and a spiral shaft 2 which are threadedly connected to each other as a whole, one end of the spiral shaft 1 is drivingly connected to the first driving device, the other end face of the spiral shaft 1 has a countersunk hole for installing a spring, the spiral shaft 2 is a hollow structure, the central push rod is threadedly connected to the inner hole of one end of the spiral shaft 2, one end of the central push rod abuts against the spring and the other end is threadedly connected to the conical head, and the cutter head shell is threadedly connected to the outer circle of the other end of the spiral shaft 2. The above structural design can flexibly adjust the cutter head action radius and facilitate the replacement of the cutter head after wear.

[0008] The central mandrel is also provided with a positioning hole whose axis is located in the radial direction. The positioning pin provided in the positioning hole is fixed by the positioning pin hole provided on the spiral shaft 2. The positioning pin holes are arranged in a row along the axis direction on the spiral shaft 2. The spacing between the positioning pin holes is an integral multiple of the pitch of the inner hole thread on the spiral shaft 2. The above structural design can position the central mandrel when necessary, prevent the cutter head from retracting, and handle hard lumps that are difficult to clean.

[0009] The outer circles of the spiral shafts one and two are provided with spirally arranged spiral blades, an outer sleeve is provided outside the outer circle of the spiral blades, and a discharge port is provided on the outer sleeve away from the adjustable tunneling head. When the tunneling head crushes the material, the crushed material is transported from the tunneling head to the outside of the pipeline driven by the rotating motion of the spiral blades, so that the blockage is quickly discharged, and it is also beneficial to the collection and treatment of the discharged material.

[0010] When using common equipment such as electric hammers for cleaning, if encountering harder materials, problems such as slipping and deviation often occur. In order to avoid slipping and deviation of the tunneling head, a three-claw positioning claw is provided on the outer sleeve of the spiral tube adjacent to the adjustable tunneling head. With the help of the positioning claw, the main body of the clearing equipment is fixed on the pipe to be cleaned and its concentricity with the pipe is guaranteed.

[0011] The support comprises a longitudinal and transverse feeding mechanism and a second driving device installed on the lifting platform and connected to each other in a transmission manner. The longitudinal and transverse feeding mechanism comprises a longitudinal feeding slide slidably connected to the lifting platform and a transverse feeding slide slidably connected to the longitudinal feeding slide. The longitudinal and transverse feeding actions of the lifting platform are realized through the driving device and the longitudinal and transverse feeding mechanism, thereby realizing the automatic feeding action of the pipeline dredging component and realizing the automation of the dredging device.

[0012] The lifting platform is a slide connected to the column in a sliding manner. The lifting platform is transmission-connected to the third driving device, so as to facilitate the adjustment of the tunneling pipe assembly to a height position corresponding to the pipeline to be cleaned.

[0013] The beneficial effects of the utility model are as follows: by designing a rotatable and adjustable tunneling pipe assembly to replace manual labor to complete the cleaning of the chloride process titanium dioxide conveying pipeline, it is possible to reduce manpower consumption, improve labor efficiency, and reduce labor injuries.

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] Example:

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the dredging device for chloride titanium dioxide conveying pipeline of the utility model includes a support 5 which can realize three-dimensional displacement adjustment and a pipeline dredging component installed on the support 5, the pipeline dredging component includes a boring pipe component connected to a first driving device 6 through a transmission device and rotates with the first driving device 6, the boring pipe assembly includes a spiral tube 9 and a retractable center push rod 10 coaxially installed in the center of the spiral tube 9, an adjustable boring head 13 is installed on the head of the center push rod 10, and a cutter head 133 with an adjustable effective diameter range is assembled on the adjustable boring head 13.

[0022] Specifically, if Figure 2 As shown, in order to adjust the effective diameter range of the cutter head, the adjustable boring head 13 includes a conical head 131, a cutter head shell 132 and two or more cutter heads 133 slidably assembled on the cutter head shell 132 and arranged in a central symmetrical manner. The conical head 131 is connected to the end of the center push rod 10, the bottom of the cutter head 133 abuts against the conical head 131, the axis of the cutter head 133 is perpendicular to the cone surface generatrix of the conical head 131, and the cutter head shell 132 is fixed to the end of the spiral tube 9.

[0023] Furthermore, in order to facilitate the replacement of worn cutter heads, such as Figure 1 , Figure 2 As shown, the spiral tube 9 includes a spiral shaft 1 91 and a spiral shaft 2 92 which are threadedly connected to each other as a whole. One end of the spiral shaft 1 91 is drivingly connected to the first drive device 6, and the end face of the other end of the spiral shaft 1 91 has a countersunk hole for installing a spring 93. The spiral shaft 2 92 is a hollow structure. The central mandrel 10 is threadedly connected to the inner hole of one end of the spiral shaft 2 92. One end of the central mandrel 10 abuts against the spring 93 and the other end is threadedly connected to the conical head 131. The cutter head shell 132 is threadedly connected to the outer circle of the other end of the spiral shaft 2 92. The threaded connection between the above-mentioned components is convenient for assembly and replacement of the cutter head 133. When only adjusting the stroke of the central mandrel is not enough to achieve large-diameter pipeline dredging operations, a larger or smaller adjustable boring head 13 can be replaced. Figure 2 The threaded connection between the center push rod 10 and the conical head 131 is not shown in the figure.

[0024] like Figure 2 As shown, a positioning hole 100 is also provided on the center push rod 10, and the axis of the positioning hole 100 is located in the radial direction. When the center push rod 10 is rotated to make the extension of the cutter head reach the required requirement, the center push rod 10 can be locked so that the clearing diameter can be adjusted within a certain range.

[0025] like Figure 1 and Figure 2As shown, spiral blades 12 are arranged in a spiral shape on the outer circles of the spiral shaft 1 91 and the spiral shaft 2 92, and after the two shafts are connected and fixed to each other, the spiral blades 12 on the two shafts are connected to each other, an outer sleeve 90 is provided on the outer sleeve 90 away from the adjustable tunneling head 13, and a discharge port 8 is provided. After the tunneling head crushes the material, the crushed material is transported from the tunneling head to the outside of the pipeline driven by the rotation of the spiral blades 12, and the discharged material can be collected and processed through the discharge port 8.

[0026] like Figure 1 As shown, a three-claw positioning claw 11 which can slide along the outer sleeve 90 is provided on the outer sleeve 90 at one end of the spiral tube 9 adjacent to the adjustable tunneling head 13. The three-claw positioning claw 11 can refer to the existing technology and is used to connect with the outer circle of the end of the pipe to be cleaned. Its structure will not be described in detail. With the help of the claw, the main body of the clearing equipment can be firmly fixed on the pipe and its concentricity with the pipe is guaranteed. In order to reduce the friction between the clearing tool and the three-claw positioning device during tunneling, a roller structure can be provided at the contact position between the inner circle of the three-claw and the pipe to avoid damage to the equipment.

[0027] like Figure 1 and Figure 3 As shown, the support 5 includes a longitudinal and transverse feeding mechanism and a second driving device 3 installed on a lifting platform 50 and connected to each other in a transmission manner. The longitudinal and transverse feeding mechanism includes a longitudinal feeding slide 51 slidably connected to the lifting platform 50 and a transverse feeding slide 52 slidably connected to the longitudinal feeding slide 51. Specifically, the second driving device 3 can be connected in a transmission manner with a gear 1, which meshes with a gear in a direction switching box 500. There are two other gears in the direction switching box 500, which respectively cooperate with the longitudinal motion gear 501 and the transverse motion gear 502, and rotate or slide the direction switching box 500, so that the second driving device 3 switches between operating the longitudinal and transverse motions. The structure is similar to the feed table of a lathe.

[0028] like Figure 1 and Figure 4 As shown, the lifting platform 50 is a sliding platform slidably connected to the column 205, and the lifting platform 50 is transmission-connected to the third driving device 2. Specifically, the third driving device 2 is transmission-connected to the gear 2, and the gear meshing with the gear 2 is transmission-connected to the drum 203 installed on a pair of support seats 202, and one end of the pull rope 204 of the drum 203 is fixed on the lifting platform 50, and the lifting platform 50 is slidingly matched with the column 205 and guided by the column, and the column 205 is fixed on the base 1. When the third driving device 2 drives the drum 203 to rotate, the pull rope 204 drives the lifting platform 50 to rise along the column 205, and when it rotates in the opposite direction, the pull rope 204 drives the lifting platform 50 to descend along the column 205.

[0029] The above-mentioned first drive device 6, second drive device 3 and third drive device 2 all use motors, among which the third drive device is installed on the base 1, and is used for the lifting and lowering adjustment and alignment of the pipeline clearing component. The second drive device 3 is installed on the lifting platform, and is used for the longitudinal and lateral feed adjustment of the cutter head. The first drive device 6 is installed on the support 5, and is used to drive the excavation head and the cutter head to rotate.

[0030] In addition, a support frame 14 is also provided on the support 5 for auxiliary support and fixing the outer sleeve 90. The base 1 itself can also adopt a liftable lifting seat.

[0031] Before cleaning the pipeline, the three-claw positioning claw 11 is used to position and install the tunneling pipe assembly on the pipeline, and the third drive device 2 and the base 1 are used to adjust and align the center of the pipeline. The position between the adjustable tunneling head 13 and the pipeline is adjusted by the center push rod 10. After the adjustment, the first drive device 6 is started; the adjustable tunneling head 13 is driven to rotate through the transmission 7, and the second drive device 3 is started at the same time to make the adjustable tunneling head 13 perform longitudinal feeding movement. The excavated materials are transported in the spiral tube 9 through the movement of the spiral blade 12, and finally discharged from the discharge port 8 to complete the cleaning work.

[0032] The use of the dredging device of the utility model can reduce the labor intensity when cleaning the titanium tetrachloride pipeline, improve the work efficiency of cleaning the titanium tetrachloride pipeline, greatly reduce the risk of personal injury when cleaning the titanium tetrachloride pipeline, and realize the semi-automation of the cleaning work.
