Description

Technical Field

[0001] The invention relates to the technical field of electrode rod installation, and in particular to a device for assisting the installation of an electrode rod, a reaction kettle and an assembly method. Background Art

[0002] The polyethylene reactor is an essential core equipment in the polyethylene production process. A motor is installed inside the reactor to provide stirring power for the polyethylene polymerization reaction. The power supply of the motor comes from the electrode rod. The electrode rod needs to be inserted into the reactor from the mounting hole on the reactor top cover to connect with the motor. Since a certain pressure needs to be maintained inside the reactor during the production process, it is necessary to have good sealing at the position where the electrode rod contacts the mounting hole. Therefore, high assembly accuracy is required for the electrode rod, and the electrode rod needs to be aligned with the mounting hole to ensure uniform force between the electrode rod and the mounting hole wall. During the disassembly process, since the sealing at the position where the electrode rod contacts the mounting hole is good, a large force is required for disassembly, which can easily cause damage to the electrode rod or the reactor top cover due to uneven force.

[0003] The prior art relies on workers' experience to use simple tools to assemble and disassemble the electrode rod. When assembling the electrode rod, the centering accuracy between the electrode rod and the mounting hole is low, which leads to poor sealing between the electrode rod and the mounting hole wall. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art that when assembling the electrode rod, the alignment accuracy between the electrode rod and the mounting hole is low, which leads to poor sealing between the electrode rod and the wall of the mounting hole, and to provide a device, a reactor and an assembly method for assisting the installation of the electrode rod.

[0005] In a first aspect, the present invention provides a device for assisting the installation of an electrode rod, comprising a centering mechanism and a feeding mechanism, wherein the centering mechanism is connected to the feeding mechanism, the centering mechanism is provided with a centering hole, the centering mechanism comprises a plurality of positioning members, the plurality of positioning members are uniformly arranged along the circumference of the inner wall of the centering hole, the plurality of positioning members all protrude from one side of the centering hole, the plurality of positioning members all can synchronously move radially along the centering hole, the feeding mechanism is used to connect the electrode rod, and the feeding mechanism can move the electrode rod along the axis of the centering hole.

[0006] The centering mechanism is used to align the axis of the electrode rod and the center point of the centering hole on the same straight line, and the mounting hole is used to install the electrode rod. By setting the centering hole, after the centering hole and the mounting hole are aligned, the electrode rod can directly pass through the centering hole into the mounting hole to complete the installation, which simplifies the installation process of the electrode rod and improves the installation accuracy of the electrode rod; by providing a plurality of positioning members on the circumferential direction of the inner wall of the centering hole, the plurality of positioning members can synchronously move along the radial direction of the centering hole, and the sides of the plurality of positioning members protruding from the centering mechanism can extend into the mounting hole, and the positioning members can move toward the axis of the centering hole, and the spacing between the positioning members is reduced so that the size of the area surrounded by the positioning members in the cross section is smaller than the size of the mounting hole, so that the side of the positioning members protruding from the centering mechanism can enter the mounting hole, and when the positioning member is moved in a direction away from the axis of the centering hole, due to the The parts move synchronously at the same speed. When the centering hole is not completely aligned with the mounting hole, one or more of the positioning parts will first contact the mounting hole wall. The positioning parts that first contact the mounting hole wall will abut against the mounting hole wall and apply a force to the mounting hole wall. The mounting hole wall applies a force in the opposite direction to the positioning parts, so that the device is displaced, so that the centering hole is gradually aligned with the mounting hole. The position of the feeding mechanism is located on the axis of the centering hole. When the electrode rod is installed on the feeding mechanism, the axis of the electrode rod is displaced in the same straight line as the axis of the centering hole, that is, when the centering hole and the mounting hole are completely aligned, the axis of the electrode rod is also completely aligned with the mounting hole. By operating the feeding mechanism, the electrode rod can be moved along the axis of the electrode rod, which increases the probability of the electrode rod moving while keeping the centering state with the mounting hole during the installation process, thereby improving the accuracy of the electrode rod installation.

[0007] The number of the positioning members is at least 3, preferably 8.

[0008] The centering mechanism includes a positioning plate, and several of the positioning members are positioning blocks. The positioning plate is provided with several grooves corresponding to the positioning blocks, and sliders are slidably arranged in the several grooves. Several of the positioning blocks are respectively connected to the positioning plate through corresponding sliders. The positioning plate is connected to a first driving member, and the first driving member can make several of the sliders slide synchronously relative to the positioning plate.

[0009] The positioning plate can be circular or rectangular, etc. The centering hole matches the shape of the mounting hole. The centering hole can be opened at any part of the positioning plate. By operating the first driving member, the plurality of sliders can be synchronously slid relative to the positioning plate, and then the slider drives the positioning block to move synchronously along the radial direction of the centering hole. The movement path of the slider can be limited by setting the slider to slide in the groove. By setting the same groove, the movement paths of the plurality of sliders can be the same when they are displaced, thereby improving the synchronization of the positioning block when it is displaced.

[0010] The positioning block may also be connected to the positioning plate through a telescopic member and other components. The first driving member can drive the telescopic member to extend or contract synchronously, and the telescopic member drives the positioning block to move synchronously.

[0011] The first driving member may be a hydraulic pump or a motor.

[0012] Preferably, the positioning plate is circular, and the centering hole is a concentric hole opened in the positioning plate.

[0013] Preferably, the positioning plate includes a rotating plate, the number of the grooves and the positioning blocks are both 8, the grooves are strip-shaped grooves arranged on the rotating plate, the first driving member is connected to the rotating plate and is used to rotate the rotating plate, and when the rotating plate rotates, the slider can move radially along the centering hole.

[0014] The feeding mechanism comprises a feeding member and a second driving member, wherein the feeding member is connected to the second driving member, and the second driving member can move the feeding member along the axis of the centering hole.

[0015] One end of the electrode rod is connected to the feed member. When the electrode rod is connected to the feed member, the axis of the electrode rod and the center point of the centering hole are located in the same straight line. Operating the second driving member can make the feed member move along the axial direction of the electrode rod, thereby driving the electrode rod to move along the axial direction of the electrode rod.

[0016] This arrangement improves the stability of the electrode rod during installation and the degree to which the force applied to the wall of the installation hole is evenly distributed, thereby reducing the risk of the electrode rod scratching the wall of the installation hole during installation.

[0017] The feeding member may be a telescopic rod or a lead screw, and the second driving member may be a motor or a hand wheel matching the lead screw.

[0018] Preferably, the feeding member is a lead screw, and the second driving member is a rotating wheel, and rotating the rotating wheel can cause the lead screw to move along the axial direction of the lead screw.

[0019] The feeding member is detachably connected with a connecting portion, the electrode rod is connected to the feeding member via the connecting portion, and the feeding member is provided with a scale.

[0020] The connection part can be replaced according to electrode rods of different specifications, thereby improving the adaptability of the device. The connection part can be screwed to the electrode rod or can be clamped to the electrode rod.

[0021] By setting the scale, the displacement degree of the electrode rod can be observed when the electrode rod is moved, thereby improving the accuracy of the electrode rod installation.

[0022] The side of the centering mechanism that is in contact with the surface where the mounting hole is located is provided with an electromagnetic base, and the electromagnetic base can be adsorbed on the surface where the mounting hole is located.

[0023] By setting an electromagnetic base, when the device is aligned with the mounting hole, the electromagnetic base is operated to generate magnetic force, and the electromagnetic base is adsorbed to the surface where the mounting hole is located, thereby relatively fixing the position of the device and the mounting hole, thereby improving the stability when installing the electrode rod.

[0024] The centering mechanism is provided with a levelness detection device.

[0025] By setting up a level detection device, the levelness of the centering mechanism can be observed, and then the levelness of the centering mechanism relative to the surface where the installation hole is located can be understood, thereby improving the accuracy of electrode rod installation.

[0026] The level detection device can be a bubble level detector or an electronic level detector, etc.

[0027] There are several electromagnetic bases, and each of the several electromagnetic bases is provided with an adjusting device, and the adjusting device is used to adjust the distance between the electromagnetic base and the centering mechanism.

[0028] By setting up an adjustment device, the distance between the electromagnetic base and the centering mechanism can be adjusted. When the number of electromagnetic bases is several, the inclination degree of the centering mechanism can be changed by adjusting the distance between each electromagnetic base and the centering mechanism, thereby affecting the horizontality of the centering mechanism. Through this setting, the ability of the device to adjust the horizontality is improved, and the adaptability of the device during use is improved.

[0029] The adjusting device may be a telescopic rod or a lead screw or the like.

[0030] In a second aspect, the present invention provides a reaction kettle, which adopts the device for assisting the installation of electrode rods.

[0037] By using the device according to the method of use, the accuracy of the electrode rod during installation can be improved, and the probability of the electrode rod being tilted and scratched due to unstable force during installation is reduced.
