Abstract
Description
Technical Field
[0001] This utility model relates to a set of automatic metering and filling devices. Background Technology
[0002] Finished product packaging is the final major step in the carbon molecular sieve production process. Based on product performance requirements, the cold material must be rapidly filled into 20kg chemical drums, with a filling target of 1800kg per hour. The drum openings are then immediately heat-sealed with aluminum-plastic film, capped, labeled, and stored. The conventional filling process involves elevating the cooling tank, installing a valved discharge port at the bottom, inserting the smaller end of a funnel into the drum, moving the drum to the discharge port position, aligning it with the wider opening of the funnel, and opening the ball valve to release the material into the drum. Because the drum space is relatively compact, especially when the material density is low, 20kg can only be filled when the material is firmly packed. This requires vigorous shaking of the drum while feeding the material—simultaneously compacting and feeding—and real-time weighing on an electronic scale.
[0003] The main problems with this filling method are as follows: (1) There is some spillage and dust during the filling process; (2) The labor intensity of the filling is high and two people need to work together; (3) The material is impacted by the strong shaking during filling and the surface is worn, which affects the quality of the product. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a set of automatic metering and filling devices, which aims to overcome problems such as material loss in the packaging process, poor working environment (dust), high labor intensity and wear on the surface of materials.
[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: an automatic metering and filling device, including a large hopper, a main support, a left filling device, a right filling device, and a fixed flange seat; the large hopper is located on the upper part of the main support and is fixed on the main support; the left filling device and the right filling device are symmetrically distributed inside the main support; the fixed flange seat is located below the main support and supports the entire main support.
[0006] The left filling device includes a left metering chamber, a left metering scale, a left material buffer chamber, a left corrugated hose, a left material hopper, a left vibrating support, and a left vibrator. The left metering chamber is located below the large material hopper and carries the material output from the large material hopper. The left metering scale is located below the left metering chamber and is used to measure the weight of the material in the left metering chamber.

The right filling device includes a right metering chamber, a right metering scale, and a right material buffer chamber. The system comprises a buffer hopper, a right corrugated hose, a right material hopper, a right vibrating support, and a right vibrator. The right metering hopper is located below the large material hopper and carries the material output from the large material hopper. The right weighing scale is located below the right metering hopper and is used to measure the weight of the material within the right metering hopper. The right material buffer hopper is connected upwards to the right metering hopper and downwards to the right corrugated hose. The right corrugated hose is connected to the right material hopper for filling. The right vibrating support is located below the right material hopper and carries the right material hopper. The right vibrator is located below the right vibrating support and is connected to the right vibrating support. A left front discharge valve, a left rear discharge valve, a right front discharge valve, and a right rear discharge valve are provided between the large material hopper and the left and right metering hoppers.

[0009] Furthermore, the left front discharge valve and the right front discharge valve close first when the weighing reaches the standard value to reduce the discharge speed of the large hopper. When the left rear discharge valve and the right rear discharge valve close, the weight of the material falling into the pipeline needs to be calculated.
[0010] Furthermore, a left metering discharge valve is provided between the left metering chamber and the left material buffer chamber, and a right metering discharge valve is provided between the right metering chamber and the right material buffer chamber; both the left metering discharge valve and the right metering discharge valve are electric ball valves.
[0011] Furthermore, the main support is internally sealed and operates under negative pressure.

The right vibrator 11-2 is located below the right vibration support 9-2 and is connected to the right vibration support 9-2.
[0022] A left front discharge valve 2-1, a left rear discharge valve 2-2, a right front discharge valve 2-3, and a right rear discharge valve 2-4 are provided between the large hopper 1 and the left metering hopper 3-1 and the right metering hopper 3-2.
[0023] In one embodiment, the opening diameter of the left front discharge valve 2-1 is twice that of the left rear discharge valve 2-2; the opening diameter of the right front discharge valve 2-3 is twice that of the right rear discharge valve 2-4; the left front discharge valve 2-1, the left rear discharge valve 2-2, the right front discharge valve 2-3, and the right rear discharge valve 2-4 all adopt a start-up gate valve; the left front discharge valve 2-1 and the right front discharge valve 2-3 close first when the weighing reaches the standard value to reduce the discharge speed of the large hopper 1; when the left rear discharge valve 2-2 and the right rear discharge valve 2-4 are closed, the weight of the material falling in the pipeline needs to be calculated.
[0024] In one embodiment, a left metering discharge valve 5-1 is provided between the left metering chamber 3-1 and the left material buffer chamber 6-1, and a right metering discharge valve 5-2 is provided between the right metering chamber 3-2 and the right material buffer chamber 6-2; both the left metering discharge valve 5-1 and the right metering discharge valve 5-2 are electric ball valves.
[0025] In one embodiment, the main support 12 is internally sealed and operates under negative pressure; the left filling device and the right filling device operate synchronously.
[0026] In one embodiment, a left vibration base plate 10-1 is provided below the left vibration bracket 9-1, and the left vibration base plate 10-1 is fixedly connected to the left vibration bracket 9-1 and connected to the main bracket 12 by a spring.

[0027] In one embodiment, during the filling operation, a Z-shaped elevator lifts the material from the discharge port of the mixing tank into the top large silo 1. The large silo 1 is equipped with a level gauge, which interlocks with the discharge valve of the mixing tank. The worker places the left material bucket 8-1, which is to be filled, onto the left vibrating support 9-1, and then inserts the bottom end interface of the left corrugated hose 7-1 at the discharge end of the left material buffer silo 6-1 into the opening of the left material bucket 8-1, thus completing the filling preparation.
[0028] Press the start button simultaneously with both hands to begin filling. At this time, the left front discharge valve 2-1 and the left rear discharge valve 2-2 at the bottom of the large material hopper 1 open simultaneously, and begin discharging material into the left metering hopper 3-1 at full diameter. The left metering scale 4-1 weighs the material in the left metering hopper in real time. When the weighing reaches 18.5kg, the left front discharge valve 2-1 closes, which reduces the diameter of the discharge port. Currently, the diameter is reduced to about 1 / 3. When the weighing reaches 19.8kg, the left rear discharge valve 2-2 closes. After the material falling from the air into the hopper, the weighing value stabilizes at 20kg ± 0.2%. The entire weighing process takes only 20 seconds.
[0029] After the left metering chamber 3-1 completes metering, the bottom left metering discharge valve 5-1 opens, and the material flows quickly into the left material buffer chamber 6-1. The material is discharged at a constant speed from the discharge port of the left material buffer chamber 6-1 and enters the left material bucket 8-1 through the left corrugated hose 7-1 to begin filling. After the material in the left metering chamber 3-1 is emptied, the bottom left metering discharge valve 5-1 closes, and the left front discharge valve 2-1 and left rear discharge valve 2-2 of the large material bin 1 open. The left metering chamber 3-1 begins a new round of feeding and metering, that is, filling and metering are carried out simultaneously.
[0030] After 35 seconds of bottom filling, the left vibrator 11-1 starts, and the left material bucket 8-1 feeds while vibrating. Filling is completed after 20 seconds of vibration. The manual disconnection of the feed hose is then performed, and the bucket is pushed away from the filling station. A powered roller conveyor belt then transports the bucket to the next station (automatic capping). The bucket is then swayed and the start button is pressed again. At this point, the left metering chamber 3-1 has already completed metering, and the bottom left metering discharge valve 5-1 automatically opens for the next round of filling. The entire filling process is conducted in a closed environment under negative pressure.
[0031] Single-bucket filling cycle time calculation: Remove the corrugated hose connector, push away the filled bucket, place the bucket to be filled, insert the corrugated hose connector, press the start button, which takes approximately 12 seconds. Material filling takes 30 + 15 = 45 seconds. Platform descent takes 3 seconds, for a total time of 12 + 45 + 3 = 60 seconds. The hourly capacity is 3600 / 60 * 20 = 1200 kg. With two filling lines, the total capacity is 1200 * 2 = 2400 kg / h. This is sufficient to meet the filling speed requirement of 1800 kg per hour, while also allowing for future capacity expansion.
[0032] This utility model is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort shall fall within the protection scope of this utility model.
