Description

Technical Field

[0001] This utility model relates to the field of packing compaction technology, and in particular to an electromagnetic automatic packing compaction device. Background Technology

[0002] In distillation processes in industries such as chemical and pharmaceutical manufacturing, the compaction quality of the packing material inside the distillation column directly affects distillation efficiency and product purity. Therefore, packing compaction is a crucial step in the distillation column preparation process. Currently, the industry generally uses traditional manual methods for loading and compacting bulk packing. The specific process is as follows: a pulley system is pre-suspended above the distillation column. Operators tie one end of a rope to the top of a compaction hammer, and the other end extends to the ground after passing through the pulley system. Four to five operators work together to pull the rope backward to raise the hammer. Once the hammer reaches the predetermined height, they simultaneously release the rope, allowing the hammer to fall freely and compact the packing material inside the column.

[0003] However, this traditional method has many insurmountable drawbacks: 1. Unstable compaction quality: Manual operation cannot guarantee consistent hammer lifting height each time, resulting in uneven compaction force; and it is impossible to monitor the actual thickness of the compacted material in real time, only to roughly judge the compaction effect by the number of hammer releases, which can easily cause excessive deviation in the height of each layer of packing, affecting the subsequent operating efficiency of the distillation column; 2. Low operating efficiency and high cost: It requires multiple people to work together, resulting in high labor costs. At the same time, the repetitive and labor-intensive action of manually lifting the hammer leads to low operating efficiency and makes it difficult to meet the needs of large-scale production; 3. Prominent safety hazards: During manual lifting, the rope is prone to detachment due to wear and uneven force, or the hammer may fall accidentally due to operator error, posing safety risks such as injury or dragging; 4. Insufficient precision in controlling the amount of packing: The packing is entirely dependent on manual dumping, which cannot achieve quantitative delivery, easily causing local packing accumulation or insufficiency, further affecting the uniformity of compaction. Utility Model Content

[0004] The purpose of this invention is to solve the problems of low efficiency, uneven compaction, inability to monitor in real time, significant safety hazards, and inaccurate control of filler quantity in existing manual compaction techniques, and to propose an electromagnetic automatic filler compaction device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electromagnetic automatic packing tamping device includes a guiding mechanism, a locking platform, a quantitative spiral packing conveying device, an electromagnetic tamping assembly, an infrared rangefinder, and an electrical control box. The guiding mechanism is installed above the distillation column to guide the lifting and lowering movement of the tamping hammer. The locking platform is located below the distillation column, and its top is equipped with a servo high-frequency electric push rod mechanism. The output end of the servo high-frequency electric push rod mechanism is connected to a semi-circular locking mechanism for fastening distillation columns of different diameters. The quantitative spiral packing conveying device is used to convey the packing into the distillation column.

[0007] The electromagnetic tamping assembly includes an automatic hoist, an electromagnetic device, and a tamping hammer. The automatic hoist is used to drive the electromagnetic device and the attracted tamping hammer to rise and fall. When the electromagnetic device is energized, it magnetically attracts the tamping hammer, and when the power is off, it releases the tamping hammer. The infrared rangefinder is used to measure the distance before and after each tamping operation and transmit the data to the electrical control box. The electrical control box is electrically connected to each component and is used to control the operation of each component and display data.

[0008] Preferably, the quantitative spiral packing conveying device is installed on the maintenance platform and includes a hopper, a spiral mechanism and a feeding mechanism. The packing enters the distillation column through the feeding mechanism.

[0009] Preferably, the servo high-frequency electric actuator mechanism has at least two sets, symmetrically distributed on the top of the locking platform, and the output end of each set of the servo high-frequency electric actuator mechanism is connected to a semi-circular locking mechanism.

[0010] Preferably, the infrared rangefinder is installed on the electromagnetic compaction assembly to measure the distance between the compaction material and the material in real time.

[0011] Preferably, the automatic hoist is installed above the maintenance platform, and the electromagnetic device is connected to the automatic hoist. When the electromagnetic device is energized, it magnetically attracts the tamping hammer, pulls it up to the set height, and then cuts off the power, causing the tamping hammer to fall and tamp the material.

[0012] Preferably, the electrical control box is equipped with a display for displaying the data transmitted by the infrared rangefinder and the working status of each component in real time.

[0013] Compared with the prior art, the present invention provides an electromagnetic automatic filling and compaction device, which has the following beneficial effects.

[0014] 1. This utility model automates the compaction process by replacing manual lifting of the heavy hammer with an automatic lifting machine and an electromagnetic device. No manual intervention is required, and only 1-2 operators are needed to complete the work, which greatly improves work efficiency and reduces labor costs. The distance before and after compaction is measured in real time by an infrared rangefinder, and the data is displayed in real time through the electrical control box, which makes it easy for operators to monitor the compaction effect and ensure that the thickness of each layer of compacted material meets the process requirements. This solves the problem of uneven compaction caused by manual operation.

[0015] 2. This utility model uses a quantitative spiral packing conveying device to precisely control the discharge amount by the number of rotations of the spiral mechanism. The total discharge amount can be set according to process requirements, avoiding errors from manual feeding and ensuring the consistency of the packing amount. The semi-circular locking mechanism of the locking platform, in conjunction with a servo high-frequency electric push rod, can be adjusted to adapt to distillation columns of different diameters, thereby improving the equipment's versatility.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4 An electromagnetic automatic packing compaction device includes a guiding mechanism 1, a locking platform 2, a quantitative spiral packing conveying device 3, an electromagnetic compaction assembly 4, an infrared rangefinder 5, and an electrical control box 6. The components work together to complete the automated compaction of the packing in the distillation column 7.

[0025] The guide mechanism 1 is a frame structure with a lifting lug on the top. It is hoisted and fixed directly above the distillation column 7 by an overhead crane. The guide mechanism 1 has a through guide channel in the vertical direction. The cross-sectional shape of the channel is adapted to the cross-sectional shape of the tamping hammer 43, which can form a circumferential limit on the lifting and lowering movement of the tamping hammer 43, ensuring that it always moves in the vertical direction and avoiding deviation of the tamping position or collision with the inner wall of the distillation column 7 due to offset.

[0026] The locking platform 2 is a horizontal load-bearing structure, located at the bottom support area of ​​the distillation column 7, used to fix the distillation column 7 to ensure the stability of the compaction process. At least two sets of servo high-frequency electric push rod mechanisms 21 are symmetrically installed on its top. The output end of each set of servo high-frequency electric push rod mechanisms 21 is fixedly connected to a semi-circular locking mechanism 22 by bolts. The inner wall of the semi-circular locking mechanism 22 is provided with an anti-slip rubber pad, which can increase the friction with the outer wall of the distillation column 7.

[0027] When the distillation column 7 is hoisted to the center of the locking platform 2, the electrical control box 6 controls the extension of the servo high-frequency electric push rod mechanism 21, driving the two semi-circular locking mechanisms 22 to approach each other in the horizontal direction until they clamp the outer wall of the distillation column 7. For distillation columns 7 of different diameters, the extension and retraction of the servo high-frequency electric push rod mechanism 21 can be adjusted by the electrical control box 6 so that the clamping amplitude of the semi-circular locking mechanism 22 is adapted to the diameter of the column body.

[0028] A quantitative spiral packing conveyor 3 is installed on the maintenance platform and is used to accurately convey packing into the distillation column 7. It includes a hopper 31, a spiral mechanism 32 and a feeding mechanism 33 connected in sequence.

[0029] The hopper 31 is a cylindrical container with an open top, and its volume is designed to accommodate 50 liters of bulk filler. The bottom has a discharge port that connects to the feed end of the screw mechanism 32.

[0030] The spiral mechanism 32 includes a horizontally arranged conveying pipe and built-in spiral blades. One end of the conveying pipe is connected to the discharge port of the hopper 31, and the other end is connected to the feeding mechanism 33. The spiral blades are driven to rotate by a drive motor. The pitch and blade diameter are designed to ensure that 2 liters of filler can be pushed from the conveying pipe to the feeding mechanism 33 with each rotation.

[0031] The feeding mechanism 33 is an inclined feed pipe, with its high end connected to the discharge end of the screw mechanism 32 and its low end extending to the top opening of the distillation column 7, so that the conveyed packing slides down the feed pipe into the interior of the distillation column 7.

[0032] The electromagnetic tamping assembly 4 is used to realize the automated tamping of the packing inside the tower, including an automatic hoist 41, an electromagnetic device 42, and a tamping hammer 43.

[0033] The automatic hoist 41 is an electric winch structure, fixedly installed on the upper beam of the maintenance platform. Its output end is connected to the electromagnetic device 42 through a high-strength rope. It can drive the electromagnetic device 42 and the tamping hammer 43 to rise and fall vertically through forward and reverse rotation. The lifting height of the automatic hoist 41 can be preset by the electrical control box 6 to ensure that the lifting position is consistent each time.

[0034] The electromagnetic device 42 is a disc-shaped electromagnetic chuck with a magnetic suction surface at its bottom, which is adapted to the top suction surface of the tamping hammer 43. The electromagnetic device 42 is electrically connected to the electrical control box 6. When powered on, it generates a strong magnetic force to attract the tamping hammer 43. When powered off, the magnetic force disappears instantly to release the tamping hammer 43.

[0035] The tamping hammer 43 is a high-density metal block with an outer diameter slightly smaller than the inner diameter of the distillation column 7, ensuring that it can uniformly compress the packing inside the column during the falling process; the top of the tamping hammer 43 is equipped with a magnetic attraction structure that is compatible with the electromagnetic device 42, and the bottom is a flat tamping surface.

[0036] The infrared rangefinder 5 is a high-precision laser ranging device. It is mounted on the electromagnetic tamping assembly 4 via a bracket. Its measuring direction is vertically downward, facing the top surface of the tamping hammer 43 or the surface of the packing material inside the tower.

[0037] The infrared rangefinder 5 is connected to the electrical control box 6 via a data cable, which can measure two sets of key data in real time: the distance between the bottom of the tamping hammer 43 and the surface of the filler before tamping, and the distance at the same position after tamping. The measurement data is transmitted to the electrical control box 6 in real time as the core parameter for judging the tamping effect.

[0038] The electrical control box 6 is an integrated control unit with a built-in PLC controller and touch display. It is electrically connected to the drive motors of the servo high-frequency electric push rod mechanism 21 and the screw mechanism 32, the automatic lifting machine 41, the electromagnetic device 42, and the infrared rangefinder 5 via cables.

[0039] Control functions: The single feeding amount of the quantitative spiral packing conveyor 3, the lifting height of the automatic elevator 41, the power-on and power-off timing of the electromagnetic device 42, and the extension and retraction of the servo high-frequency electric push rod mechanism 21 can be preset to realize the coordinated action of each component.

[0040] Display function: The display shows the data transmitted by the infrared rangefinder 5 in real time, as well as the working status of each component, such as "conveying", "lifting", "compacting completed", etc., which makes it easy for operators to monitor the operation process.

[0041] Working principle

[0042] Installation and fixing stage: The guide mechanism 1 is hoisted to the top of the distillation column 7 by the overhead crane and fixed to ensure that the movement path of the tamping hammer 43 is coaxial with the distillation column 7; the distillation column 7 is hoisted to the center of the locking platform 2, and the electrical control box 6 controls the servo high-frequency electric push rod mechanism 21 to drive the semi-circular locking mechanism 22 to hold the column body and complete the fixing.

[0043] In the packing quantitative conveying stage: 50 liters of packing are poured into the silo 31 by the overhead crane. The operator sets the single feeding amount, such as 10 liters, through the electrical control box 6. The corresponding screw mechanism 32 rotates 5 times. The drive motor drives the screw mechanism 32 to rotate. The packing is pushed to the feeding mechanism 33 by the screw blades and falls accurately into the distillation column 7 along the guide pipe.

[0044] Automated compaction stage: The electromagnetic device 42 is energized to attract the tamping hammer 43. The automatic hoist 41 drives both to descend until the tamping hammer 43 contacts the filler surface. The automatic hoist 41 raises the tamping hammer 43 to a preset height and then stops. The electromagnetic device 42 is de-energized and releases the hammer. The hammer falls under gravity to tampe the filler. After tamping, the infrared rangefinder 5 transmits the measurement data to the electrical control box 6 to determine whether the required compaction thickness has been achieved. If not, the above lifting-releasing-measuring process is repeated until the compaction thickness of the current batch of filler meets the requirements.

[0045] Cyclic operation phase: After the current batch of packing is compacted, the system automatically starts the quantitative spiral packing conveyor 3 to feed the next batch of material, repeating the compaction process until all the packing in the distillation column 7 is compacted according to the process requirements, and the system automatically stops operation.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
