Description

Technical Field

[0001] This utility model relates to the field of extraction equipment technology, specifically to an anti-clogging device for an extraction liquid pipe. Background Technology

[0002] Subcritical extraction is a novel extraction and separation technology that utilizes subcritical fluids as extractants in a closed, oxygen-free, low-pressure vessel. Based on the principle of "like dissolves like" in organic compounds, it achieves molecular diffusion between the extractant and the solid material during immersion, transferring fat-soluble components from the solid material to the liquid extractant. The extractant is then separated from the target product through reduced pressure evaporation, ultimately yielding the desired product. Subcritical extraction technology is widely used in industrial and agricultural production, primarily for the extraction of pigments, oils, and valuable oilseeds. Employing appropriately structured equipment and using an extractant to extract the desired substances from solid materials are crucial aspects of subcritical extraction technology.

[0003] Because subcritical extraction accelerates the extraction of solid materials from the solvent through stirring, it is prone to blockage by solid materials during the discharge process. Traditionally, manual unclogging is used, but this method is inefficient. Patent CN213132016U, entitled "Subcritical Extraction Equipment," discloses a backflushing device for the discharge pipe to clear blockages. While this effectively clears the pipe, unclogging it after blockage will cause the subcritical extraction device to stop operating, thus affecting its efficiency. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide an anti-clogging device for the extraction liquid tube.

[0005] According to the technical solution provided in the embodiments of this application, an anti-clogging device for an extraction liquid tube includes an inner tube, which is hollow inside. Several balls are embedded in the side end face of the inner tube. The embedded balls are connected to the inner tube by a conical spring, allowing the balls to move within and outside the inner tube. An outer tube is fitted onto the outer side of the inner tube. The upper and lower ends of the outer tube are slidably connected to the inner tube. Several holes are provided on the side end face of the outer tube. Horizontal rods are provided on the upper and lower ends of the inner tube. A rolling device is fixedly connected between the horizontal rods. The rolling device abuts against the outer tube. When the rolling device drives the outer tube to roll relative to the inner tube through friction, the balls are squeezed by the inner end face of the outer tube under the action of the conical spring, realizing the displacement change of the balls between the holes and the inner end face of the outer tube, that is, the displacement change of the balls between the outer end face and the inner end face of the inner tube, thereby realizing the knocking vibration of the wall of the extraction liquid tube fitted inside the inner tube.

[0006] Furthermore, one end of the conical spring is fixedly connected to the end face of the inner tube, and the other end is fixedly connected to the end of the ball, thereby limiting the position of the ball.

[0007] Furthermore, the larger diameter end of the conical spring is fixedly connected to the inner tube, and the smaller diameter end is fixedly connected to the ball bearing to prevent the ball bearing from shifting.

[0008] Furthermore, the rolling device includes a drive motor and a rotating rod. The drive motor is fixed on a horizontal rod, and the two ends of the rotating rod are rotatably connected to two horizontal rods respectively. The rotating rod rotates through the drive motor. Multiple rubber protrusions are provided on the side end face of the rotating rod. The rubber protrusions abut against the outer end face of the outer tube, and the rotation of the outer tube is achieved through friction, reducing the complexity of the device.

[0009] Furthermore, fastening rings are provided on both the upper and lower ends of the inner tube to facilitate the fixing of the device to the outlet pipe.

[0010] Furthermore, the fastening ring is a ring-shaped elastic band, which reduces production costs and makes it more convenient to use.

[0011] In summary, the beneficial effects of this application are as follows: the device is fitted onto the outside of the drain pipe and fixed by a fastening ring. Frequent tapping of the drain pipe's outer wall by ball bearings vibrates the outer wall, reducing the retention of solid material within the drain pipe, preventing blockage, and improving the efficiency of the drain pipe in the subcritical extraction device. Furthermore, the device is simple to use, simply fitting onto the drain pipe, and has a wide range of applications. Attached Figure Description

[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] like Figure 1 and Figure 2 As shown, an anti-clogging device for an extraction liquid tube has an outer tube 4 with several holes 41. The outer tube 4 is sleeved on the outside of the inner tube 1. The upper and lower end faces of the inner tube 1 are fixedly connected to fastening rings 7. The upper and lower end faces of the inner tube 1 are fixedly provided with horizontal rods 5. Rolling devices 6 are provided on two horizontal rods 5 located on the same vertical plane. The rolling device 6 includes a drive motor 61 fixed on the horizontal rod 5 and a rotating rod 62 that is rotated by the drive motor 61. The two ends of the rotating rod 62 are rotatably connected to the two horizontal rods 5. The rolling device 6 is provided at the left and right ends of the inner tube 1.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, the inner tube 1 is hollow inside, and several balls 2 are embedded inside the inner tube 1. Both ends of the balls 2 protrude from the surface end of the inner tube 1. Several conical springs 3 are provided on the inner end face of the inner tube 1. The conical springs 3 are used to connect the balls 2 and the inner tube 1. The larger diameter end of the conical spring 3 is fixedly connected to the inner end face of the inner tube 1, and the smaller diameter end is fixedly connected to the end of the balls 2 away from the end face of the inner tube 1. In this way, the balls 2 embedded in the inner tube 1 will not detach from the inner tube 1 and can hover between the inner end face and the outer end face of the inner tube 1.

[0022] like Figure 2 and Figure 4 As shown, annular T-shaped grooves 8 are provided at the upper and lower ends of the outer end face of the inner tube 1, and annular T-shaped protrusions (not shown in the attached drawings) corresponding to the annular T-shaped grooves 8 are provided at the upper and lower ends of the inner end face of the outer tube 4, so as to realize the connection between the outer tube 4 and the inner tube 1, and the outer tube 4 can rotate relative to the inner tube 1, that is, the outer tube 4 rotates relative to the inner tube 1 under the drive of the rolling device 6.

[0023] When in use, the device is attached to the outlet pipe by fastening ring 7. Fastening ring 7 is a ring-shaped elastic cloth that can be fastened to the outlet pipe like an elastic band.

[0024] Then start the drive motor 61. When the drive motor 61 rotates, it will drive the rotating rod 62 to rotate. The multiple rubber protrusions 63 on the rotating rod 62 will rotate. Since the rubber protrusions 63 abut against the outer tube 4, there is friction between the rubber protrusions 63 and the outer tube 4. Therefore, when the rubber protrusions 63 rotate with the rotating rod 62, they will exert a rotational force on the outer tube 4 due to the friction. Since the outer tube 4 is slidably connected to the inner tube 1, the outer tube 4 will rotate relative to the inner tube 1.

[0025] When the outer tube 4 rotates, the inner tube 1 is equipped with ball bearings 2 connected by conical springs 3. The ball bearings 2 will be in two states: a) the ball bearings 2 protruding from the outer end face of the inner tube 1 abut against the inner end face of the outer tube 4; b) the ball bearings 2 can be inserted into the hole 41 of the outer tube 4, so that the ball bearings 2 move between the inner end face and the outer end face of the inner tube 1, thereby realizing the vibration of the ball bearings 2. The vibration of the ball bearings 2 then acts on the wall of the liquid outlet pipe inside the inner tube 1, so that the wall of the liquid outlet pipe vibrates. If the rotation speed of the outer tube 4 is fast, the wall of the liquid outlet pipe can vibrate at a high frequency. In this way, the solid material flowing out of the liquid outlet pipe will not remain on its inner wall, greatly reducing the probability of blockage of the liquid outlet pipe.

[0026] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and other solutions employed. Furthermore, the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this application.
