Description

Technical Field

[0001] This utility model relates to the field of chemical material recycling, specifically a device for recycling packaging barrel residues. Background Technology

[0002] Currently, the chemical industry commonly uses 200L packaging drums to store chemical materials. The materials in these drums are typically transferred by pouring or pipe suction. However, for high-viscosity materials, a significant amount of material remains adhered to the drum walls. This results in material waste and increased production costs. While some recycling equipment exists, these devices still have various problems and cannot effectively solve the problem of recovering high-viscosity materials adhering to the drum walls. Patent document CN209127393U discloses a "chemical raw material recycling device," providing a recycling scheme including a frame, a flow guiding device fixed to the frame, and a collection box. This scheme uses a special frame to fix inverted raw material drums and uses inclined flow guiding pipes to guide residual raw materials from multiple drums into the collection box, achieving recycling entirely through gravity flow. However, when used to recycle medium- to high-viscosity raw materials, the slow or even non-flowing nature of the material results in very low recycling efficiency, or even complete failure to recycle it. Summary of the Invention

[0003] This invention provides a packaging residue recycling device that can overcome the problem that existing methods have very low efficiency in recycling medium- and high-viscosity materials adhering to the inner wall of packaging barrels, or are unable to recycle high-viscosity materials.

[0004] The packaging barrel residue recycling device of this utility model includes:

[0005] A steam jacket, cylindrical in shape, is used to fit over the outside of a packaging barrel. The steam jacket has an annular steam cavity and a steam inlet and a steam outlet that connect to the steam cavity.

[0006] A support bracket that supports the steam jacket so that its axis is inclined relative to the horizontal plane;

[0007] A rotary scraping device includes a rotating shaft, a driver for driving the rotating shaft to rotate, and a scraping mechanism connected to the rotating shaft that can rotate with the rotating shaft to scrape off residues from the inner wall of the packaging barrel. A portion of the rotating shaft and the scraper can extend into the packaging barrel.

[0008] Preferably, the axis of the steam jacket is inclined at 30°-60° relative to the horizontal plane.

[0009] Preferably, the higher end of the steam jacket has an openable and closable cover, and / or the lower end of the steam jacket is provided with a limiting structure for limiting the packaging barrel to prevent it from sliding down.

[0010] Preferably, the packaging drum residue recovery device also includes a collection device located below the lower end of the steam jacket for collecting residue flowing out of the packaging drum.

[0011] Preferably, the rotary scraping device includes two first scraping mechanisms for scraping off residue from the sidewalls of the packaging barrel. The two first scraping mechanisms are symmetrical about a plane passing through the rotation axis. Each first scraping mechanism includes a support mechanism and a first scraper. One end of the support mechanism is fixed to the rotation axis, and the other end is fixed to the first scraper. The first scraper is parallel to the axis of the rotation axis.

[0012] Preferably, the length direction of the first scraper forms an angle of 2°-15° with the axis of the rotating shaft, and in the direction of rotation of the rotating shaft, the upper end of the first scraper is in front and the lower end is behind.

[0013] Preferably, the first scraper is used to form a scraping tip at the position where it contacts the inner wall of the packaging barrel.

[0014] Preferably, the end face of the rotating shaft extending into the packaging barrel is provided with a second scraping mechanism for scraping off residue from the bottom wall of the packaging barrel.

[0015] Preferably, the second scraping mechanism includes an annular or circular mounting plate fixed to and coaxial with the end of the rotating shaft, and a plurality of second scrapers arranged circumferentially along the mounting plate, the second scrapers extending radially along the mounting plate.

[0016] Preferably, the rotating shaft is hollow, and the rotating shaft is provided with a rotating fluid joint to allow compressed gas to enter the hollow part of the rotating shaft. The support mechanism includes a sleeve fixedly connected to the rotating shaft and communicating with the hollow part of the rotating shaft, and a telescopic rod fixedly connected to the first scraper. One end of the telescopic rod extends into the sleeve, and a seal is formed between the outer wall of the telescopic rod and the inner wall of the sleeve. The sleeve is provided with an annular rebound pad that can apply a rebound force to the telescopic rod to retract it into the sleeve.

[0017] Compared with the prior art, this utility model has the following advantages: In use, the packaging barrel residue recovery device of this utility model first places the packaging barrel into a steam jacket, tilting it so that the tilt angle is basically the same as the tilt angle of the steam jacket. High-temperature steam is introduced into the steam jacket, heating the barrel wall and improving the fluidity of the residue, thereby increasing the efficiency of material recovery. Simultaneously, a drive unit rotates a rotating shaft, which in turn rotates a scraping mechanism to scrape down the residue from the inner wall of the packaging barrel. Because the packaging barrel is tilted relative to the horizontal plane, the residue flows to the lower end, allowing for collection. Compared to the natural flow of material, the scraping mechanism not only further improves the recovery efficiency but also increases the amount of material recovered. Attached Figure Description

[0029] This utility model provides a packaging barrel residue recovery device for scraping off residue from the inner wall of the packaging barrel 5, and is particularly suitable for medium and high viscosity fluid chemical materials. Figure 1 As shown, the packaging drum residue recovery device includes a steam jacket 1, a support 2, and a rotating scraper 3. The steam jacket 1 is cylindrical and fits over the outside of the packaging drum 5. The steam jacket 1 has an annular steam chamber (not shown) and a steam inlet 11 and a steam outlet 12 communicating with the steam chamber. The rotating scraper 3 includes a rotating shaft 31, a driver 32 that drives the rotating shaft 31 to rotate, and a scraping mechanism connected to the rotating shaft 31 that can scrape off residue from the inner wall of the packaging drum 5 as it rotates with the rotating shaft 31. In this embodiment, the driver 32 is a motor, and one end and part of the rotating shaft 31, along with the scraper, can extend into the inside of the packaging drum.

[0030] In use, the packaging barrel residue recovery device of this utility model first places the packaging barrel 5 into the steam jacket 1, tilting the packaging barrel 5 at an angle basically consistent with the tilt angle of the steam jacket 1, with the open end of the packaging barrel 5 being lower. High-temperature steam is introduced into the steam jacket 1, heating the barrel wall of the packaging barrel 5 and improving the fluidity of the residue, thereby increasing the efficiency of material recovery. Simultaneously, the drive 32 drives the rotating shaft 31 to rotate the scraping mechanism, scraping the residue off the inner wall of the packaging barrel 5. Because the packaging barrel 5 is tilted relative to the horizontal plane, the residue flows towards the lower end, allowing for collection. Compared to the natural flow of material, the scraping mechanism not only further improves the recovery efficiency but also increases the amount of material recovered.

[0031] Both the steam jacket 1 and the support 2 are made of metal. In this embodiment, both the steam jacket 1 and the support 2 are made of stainless steel. The support 2 includes two high vertical arms 21 of the same height and two low vertical arms 22 of the same height. One end of the steam jacket 1 is welded to the two high vertical arms 21, and the other end is welded to the two low vertical arms 22. The steam jacket 1 is preferably inclined at 30°-60° relative to the horizontal plane, more preferably within the range of 40°-50°, which allows for faster flow of residue while ensuring the stability of the steam jacket 1. Figure 1 As shown, the higher end of the steam jacket 1 has an openable and closable cover 13. When the cover 13 is closed, it can insulate the steam jacket 1 and the packaging drum 5, preventing heat loss and thus improving energy efficiency. When the cover 13 is open, it is convenient to put the packaging drum 5 into the steam jacket 1 from this point. In addition, the lower end of the steam jacket 1 is provided with a limiting structure 14 for limiting the packaging drum 5 and preventing it from sliding down, such as... Figure 1As shown, the limiting structure 14 consists of two inwardly protruding baffles. Additionally, in this embodiment, the residue recovery device for the packaging drum 5 may also include a steam generator (not shown in the figure) that supplies steam to the steam jacket 1. A steam generator with an existing structure can be used, and its structure is not specifically described here.

[0032] like Figure 1 As shown, the packaging drum residue recovery device also includes a collection device 4, which is located below the lower end of the steam jacket 1 to collect residue flowing out of the packaging drum 5. In this embodiment, the collection device 4 is a collection trough.

[0033] like Figure 2 As shown, the rotating scraping device 3 includes two first scraping mechanisms 33 for scraping off residue from the sidewalls of the packaging barrel 5. The two first scraping mechanisms 33 are symmetrical about the plane passing through the rotating shaft 31, thus making the force on the entire rotating scraping device 3 more balanced. The first scraping mechanism 33 includes a support mechanism 331 and a first scraper 332. One end of the support mechanism 331 is fixed to the rotating shaft 31, and the other end is fixed to the first scraper 332. In this embodiment, the first scraping mechanism 33 has two support mechanisms 331 and one first scraper 332. The two support mechanisms 331 are arranged along the length of the rotating shaft 31 and jointly support the same first scraper 332. The length direction of the first scraper 332 forms an angle of 2°-15° with the axis of the rotating shaft 31, and in the direction of rotation of the rotating shaft 31, the upper end of the first scraper 332 is in front and the lower end is behind. Therefore, the first scraper 332 scrapes the residue forward and downward, making it easier for the residue to flow downward. The included angle is preferably 5°-10°. For example... Figure 5 As shown, the first scraper 332 is used to form a scraping tip 3321 at the position where it contacts the inner wall of the packaging barrel 5. In this way, the first scraper 332 can form a tighter fit with the inner wall of the packaging barrel 5 and "scrape" the residue off the inner wall of the packaging barrel 5.

[0034] like Figure 2 As shown, the end face of the rotating shaft 31 that extends into the packaging barrel 5 is provided with a second scraping mechanism 34 for scraping off residue from the bottom wall of the packaging barrel 5. The second scraping mechanism 34 includes an annular or circular second scraping mechanism 34 fixed to and coaxial with the end of the rotating shaft 31, and a plurality of second scrapers 342 arranged circumferentially along the mounting plate, the second scrapers 342 extending radially along the mounting plate.

[0035] In this embodiment, as a preferred solution, the rotating shaft 31 is hollow, such as... Figure 3 and Figure 4As shown, the support mechanism 331 includes a sleeve 3311 fixedly connected to the rotating shaft 31 and communicating with the hollow portion of the rotating shaft 31, and a telescopic rod 3312 fixedly connected to the first scraper 332, as shown. Figure 3 As shown, one end of the sleeve 3311 is provided with a first mounting plate 3314, which is fixed to the rotating shaft 31 by bolts. One end of the telescopic rod 3312 is connected to an L-shaped second mounting plate 3315, which is fixed to the first scraper 332 by bolts. One end of the telescopic rod 3312 extends into the sleeve 3311, forming a seal between the outer wall of the telescopic rod 3312 and the inner wall of the sleeve 3311. The seal can be achieved by setting a sealing ring (not shown in the figure) on the outer wall of the telescopic rod 3312 or the inner wall of the sleeve 3311.

[0036] The sleeve 3311 contains an annular rebound pad 3313. The upper end of the annular rebound pad 3313 is fixed to the sleeve 3311, and the lower end of the annular rebound pad 3313 is fixed to the telescopic rod 3312. The annular rebound pad 3313 can be made of high-resilience materials such as rubber, silicone, polyurethane elastomer, or springs. Its initial compressive strength is not higher than 0.6 MPa. The pressure of the compressed air connected to the rotary fluid connector 311 is not lower than the initial compressive strength of the annular rebound pad 3313, and is not more than 0.2 MPa higher than the initial compressive strength of the annular rebound pad 3313. When compressed air passes through the rotating shaft 31, the compressed air pushes the telescopic rod 3312 outward toward the outer wall of the sleeve 3311. The greater the pressure of the compressed gas, the longer the telescopic rod 3312 protrudes. By adjusting the pressure of the compressed gas, the distance between the scraper and the rotating shaft 31 can be adjusted. This allows the diameter of the entire rotating scraping device 3 to be adjusted according to the diameter of the packaging barrel 5, thus adapting to packaging barrels 5 of different specifications. The annular rebound pad 3313 can apply a rebound force to the telescopic rod 3312, causing it to retract into the sleeve 3311. A rotary fluid connector 311 is provided at the end of the rotating shaft 31 away from the second scraping mechanism 34, allowing compressed gas to enter the hollow part of the rotating shaft 31.

[0037] In this embodiment, the packaging barrel residue recovery device may further include a gas compression device (not shown in the figure) that supplies compressed gas to the rotary fluid connector 311. The rotary fluid connector 311 and the gas compression device may adopt existing commercially available structures.

[0038] One method of using the packaging barrel residue recycling device of this utility model is as follows:

[0039] (1) Confirm that compressed air is not connected and the motor is not running;

[0040] (2) Steam is introduced into the steam jacket 1 to heat the steam jacket 1;

[0041] (3) Open the lid, put the packaging barrel 5 into the steam jacket 1, and close the lid 13;

[0042] (4) Compressed air with a pressure of 0.7MPa is introduced through the rotary fluid connector 311 until the first scraper 332 is tightly attached to the inner wall of the packaging barrel 5, with a contact pressure of 0.1-0.2MPa;

[0043] (5) Start the motor to make the rotating shaft 31, the first scraper 332 and the second scraper 342 rotate at a speed of 30 revolutions / minute to start resin recycling;

[0044] (6) After the resin recycling is completed, turn off the steam, turn off the motor, and turn off the compressed air at the same time to separate the first scraper 332 from the inner wall of the packaging barrel 5.

[0045] (7) Open the lid 13, take out the packaging barrel 5, close the lid 13, and the recycling work is completed.

The scope of protection of this utility model is defined by the claims. Various modifications or equivalent substitutions made by those skilled in the art within the spirit and scope of this utility model also fall within the scope of protection of this utility model.
