Description

Technical Field

[0001] This invention relates to the field of extrusion machine manufacturing technology, specifically to a medical tube extrusion machine equipped with a waste gas treatment device. Background Technology

[0002] An extruder is a device that processes plastic powder or plastic granules into plastic tubes. It uses a screw of a specific shape to rotate in a heated barrel, extruding the plastic fed from the hopper forward, so that the plastic is uniformly plasticized (i.e. melted), and then extruded into continuous plastic layers or plastic tubes of various shapes through the die head and different shaped molds.

[0003] According to Chinese Patent CN115230115A, an extruder with a waste gas treatment function is disclosed, comprising: a base; an extruder body, the extruder body being fixed above the base by a support; two spiral extrusion rods arranged side by side in the extruder body; a drive device disposed in the extruder body for driving the spiral extrusion rods to rotate; a feeding port disposed on the upper end face of the extruder body; a waste gas treatment device installed on the upper end of the extruder body, located to one side of the feeding port; and a molding die disposed on the extruder body at one end away from the feeding port. The waste gas treatment device includes rotating blades, a connecting passage, and a mounting body. The upper port of the connecting passage is provided with rotating blades, and its lower port is connected to the mounting body. The inner walls of the connecting passage and the mounting body are made of composite permanent magnet material. A screening plate is placed between the mounting body and the connecting passage. The screening plate is detachably mounted. The device is mounted on the mounting body, and a liquid-collecting tank is provided at the lower end of the mounting body. The exhaust gas treatment device also includes a cleaning component. The inner side of the screening plate is provided with a locking recess. When the exhaust gas treatment device needs to discharge sewage, the cleaning component moves to the edge position where the connecting passage and the rotating blade meet. The cleaning component moves spirally inside the connecting passage, and after cleaning the inner wall of the connecting passage, it moves to the locking component. Alternatively, after cleaning the connecting passage, it enters the mounting body and moves spirally to clean its inner wall. After cleaning, it moves to the locking component. By moving spirally in the connecting passage and the mounting body, the oily organic matter in the connecting passage and the mounting body can be cleaned. A magnet tightly positions the cleaning component in the inner wall of the connecting passage and the mounting body. The drive unit and the pointing unit cause the cleaning component to move spirally, thereby cleaning the oily organic matter in the connecting passage and the mounting body. The cleaned oily organic matter is collected in the recess. By replacing the cleaning component, the decontamination effect of this device can be improved.

[0004] The aforementioned pipe cleaning requires the installation of electrical products and the use of magnets. This installation is not only costly, but also presents technical problems because the pipes themselves have a certain angle, which creates dead corners inside the pipes during the cleaning process, making it impossible to clean them thoroughly. Summary of the Invention

[0017] (III) Beneficial Effects

[0018] This invention provides a medical tubing extruder with an exhaust gas treatment device. Compared with the prior art, it has the following advantages:

[0019] 1. This medical tube extruder with a waste gas treatment device utilizes a negative pressure mechanism. When airflow travels at high speed inside the annular pipe and the conveying pipe (b), negative pressure is generated inside the suction port and the layer pipe. This negative pressure draws gas from the other outlet of the extruder into the annular pipe. Simultaneously, the layer pipe, under negative pressure, draws the waste gas generated inside the extruder into the filter cartridge. Coarse-grained filter gauze removes large particles from the waste gas, followed by fine-grained filter gauze to remove fine particles. Activated carbon and a porous material filling layer adsorb odors from the waste gas. Finally, a spiral tube discharges the waste gas. When the pipes become clogged, they can be easily removed and replaced. The pressure difference allows waste gas to be drawn into the pipes. Compared to traditional cleaning mechanisms, this method only requires replacement when the pipes are clogged, resulting in lower costs and faster cleaning. Furthermore, this suction mechanism protects the exhaust fan from blockages caused by dirt.

[0020] 2. This medical tube extruder with a waste gas treatment device, through a reflux mechanism, has a fan blade fixed in a shape where one side is higher than the direction of the wind, causing the wind to blow in one direction from high to low on the fan blade surface, thereby changing the direction of the passing wind and giving the wind a turning force. The rotational force will drive the entire rotating feeding hopper to rotate. During the rotation, the movable ball bearing at the bottom of the rotating feeding hopper will rotate, thereby reducing friction and facilitating the overall rotation of the rotating feeding hopper. During rotation, centrifugal force will be used to throw the material inside the bearing cylinder out from the inside of the mesh, and then evenly throw it into the inside of the sleeve. Compared with the traditional throwing method, it can avoid accumulation. This throwing method is more uniform and heats up faster.

[0021] 3. This medical tube extruder with a waste gas treatment device allows gas to be transported into the extruder through a flow pipe via a reflux mechanism. Since the gas contains a certain amount of heat, it can preheat the extruded plastic granules, thereby assisting in heating. This allows for the recovery of waste heat energy, which in turn preheats the material, facilitating rapid melting and improving production efficiency. Attached Figure Description

[0031] The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-8This invention provides a technical solution: a medical tube extruder with a waste gas treatment device, comprising a fixed plate 1, a mounting plate 2, a drive motor 3, a belt 4, an extruder 5, and a sleeve 6. The mounting plate 2 is fixedly mounted on the top of one side of the fixed plate 1, and the drive motor 3 is fixedly mounted on the top of the mounting plate 2. The side of the drive motor 3 is connected to the back of the extruder 5 via the belt 4. A negative pressure mechanism is provided on the other side of the extruder 5; the negative pressure mechanism includes a fan 16, an injection pipe 15, a suction port 14, and a ring. The extruder 16 consists of a shaped tube 13, a layered tube 12, a conveying tube b11, a filter cartridge 10, a conveying tube a9, and a blower 16 located at the bottom of the other side of the fixed plate 1 and fixedly connected to the other side surface of the fixed plate 1. An injection tube 15 is fixedly installed on the outer wall of the blower 16. An annular tube 13 is movably sleeved inside the injection tube 15. A suction port 14 is opened inside the circumference of the annular tube 13. The conveying tube b11 is fixedly installed on the top of the annular tube 13, and the layered tube 12 is fixedly installed on the bottom of the conveying tube b11. The outer wall of the layered tube 12 is connected to the extruder 5. On the other side, they are interlocked. The outer wall of one side of the conveying pipe b11 is fixedly connected to the filter cylinder 10, and the conveying pipe a9 is threaded onto one side of the filter cylinder 10. A connector 17 is fixedly installed at the bottom of the exhaust pipe 18. An insertion interface 151 is provided inside the injection pipe 1, and the interior of the insertion interface 151 is compatible with the outer wall of the connector 17. A connection port 501 is provided at the top of the other side of the extruder 5, and the interior of the connection port 501 is interlocked with the bottom of the layer pipe 12. The interior of the filter cylinder 10 includes a threaded block 101. The filter cylinder 10 consists of a spiral tube 102, a porous material filling layer 103, activated carbon filter 104, fine particle filter gauze 105, coarse particle filter gauze 106, a threaded block 101 with internal threads on one side of the filter cylinder 10, a spiral tube 102 with fixed threads on the outer wall of the threaded block 101, and threads on the inner side of the spiral tube 102 and the outer wall of the other side of the conveying pipe a9. The filter cylinder 10 is filled with a porous material filling layer 103, activated carbon filter 104, fine particle filter gauze 105, and coarse particle filter gauze 106.

[0033] In this embodiment, when a negative pressure mechanism is required during operation, the insertion pipe 17 fixedly installed at the bottom of the exhaust pipe 18 and the insertion interface 151 opened inside the injection pipe 15 are first interlocked. During the interlocking process, the bottom of the layer pipe 12 will interlock with the inside of the connection port 501. Then, the outer wall of the threaded block 101 and the internal thread of the filter cylinder 10 are connected. After the above installation is completed, the fan 16 is started. During the start-up process of the fan 16, external air is delivered into the interior of the exhaust pipe 18. When the airflow flows at high speed inside the annular pipe 13 and the delivery pipe b11, a negative pressure is generated inside the suction port 14 and the layer pipe 12. The negative pressure generated inside the suction port 14 will draw the gas flowing out of the other outlet of the extruder 5 into the interior of the annular pipe 13. When the layer pipe 12 generates negative pressure, it will also draw the exhaust gas generated inside the extruder 5 into the interior of the filter cylinder 10. The coarse particle filter cloth 106 can filter out the large particles of the exhaust gas, and then the fine particle filter cloth 105 can filter out the fine particles inside the gas. The activated carbon filter 104 and the porous material filling layer 103 can adsorb the odor inside the exhaust gas. Then the exhaust gas can be discharged through the spiral tube 102. When there is dirt clogging inside the pipe, it can be simply pulled out and replaced.

[0034] Specifically, a reflux mechanism is provided on the top side of one side of the extruder 5; the reflux mechanism includes a sleeve 6, a rotary hopper 7, a ball bearing 701, a mesh 702, a support cylinder 703, a flow pipe 704, a circular plate 705, a fixing rod 706, and a fixing block 708. The bottom of the sleeve 6 is fixedly connected to the inside of the extruder 5. The rotary hopper 7 is movably installed inside the sleeve 6. The ball bearing 701 is movably installed on the bottom circumference of the rotary hopper 7. The support cylinder 703 is fixedly installed in the middle of the rotary hopper 7. The mesh 702 is opened on the outer circumference of the support cylinder 703. The rotary hopper 7 and the support cylinder 703 are connected. Inside each of the components, a flow tube 704 is fixedly installed. A circular plate 705 is fixedly installed on the top of the flow tube 704. A fixing block 708 is fixedly installed at the bottom of the inner cavity of the flow tube 704. A fixing rod 706 is fixedly installed on the outer wall of the fixing block 708. A fan blade 707 is fixedly installed on the outer circumference of the fixing rod 706. The fan blade 707 is located inside the flow tube 704. A sleeve opening 601 is opened inside the sleeve opening 601. An extension opening 602 is opened inside the circumference of the sleeve opening 601. The interior of the extension opening 602 is adapted to the outer wall of the bearing cylinder 703. The bottom of the ball bearing 701 is located on the circumferential surface of the sleeve opening 601.

[0035] In this embodiment, when the return mechanism is required during operation, the inner parts of the bearing cylinder 703 and the extension port 602, which are fixedly installed at the bottom of the sleeve 6, are first interlocked. This allows the bottom of the ball bearing 701 to fit against the circumferential surface of the sleeve port 601. Then, the outer walls of the circular plates 705 inside the conveying pipe a9 are interlocked. After installation, plastic granules are thrown into the interior of the rotating feeding hopper 7, and the granules enter the interior of the bearing cylinder 703. When the gas is discharged from the screw tube 102, it is directly conveyed into the interior of the conveying pipe a9. The gas is then conveyed into the interior of the flow pipe 704 through the conveying pipe a9. The airflow comes into contact with the fan blade 707 fixedly installed on the outer wall of the fixed rod 706. The fan blade 707 is fixed in a shape where one side is higher than the side lower than the airflow. The direction of the airflow can be directed to blow the air from high to low on the surface of the fan blades 707, thereby changing the direction of the passing wind and giving the wind a turning force. The rotational force will drive the entire rotating feeding hopper 7 to rotate. During the rotation, the movable ball bearings 701 at the bottom of the rotating feeding hopper 7 will rotate, thereby reducing friction and facilitating the overall rotation of the rotating feeding hopper 7. When rotating, the centrifugal force will throw the material inside the bearing cylinder 703 out from the inside of the mesh 702, and then evenly throw it into the inside of the sleeve 6 to avoid accumulation. The gas will be transported into the inside of the extruder 5 through the flow pipe 704. Because the gas has a certain amount of heat, it can preheat the scattered plastic granules, thereby assisting in heating.

[0036] Specifically, the conveying pipe a9 has a conveying cavity inside, and the inside of the conveying cavity is connected to the outer wall of the circular plate 705.

[0037] In this embodiment, by providing a conveying cavity, airflow can be conveyed into the interior of the flow pipe 704 connected to the circular plate 705.

[0038] Specifically, the annular pipe 13, the exhaust pipe 18, the conveying pipe b11, and the filter cylinder 10 all have flow chambers inside, and the flow chambers are interconnected.

[0039] In this embodiment, by providing a flow cavity, the gas can be delivered to the working position during the operation.

[0040] Specifically, the inside of the layer tube 12 is provided with an air intake chamber, and the internal diameters of the air intake chamber and the intake port 14 are both smaller than the diameter of the flow chamber.

[0041] In this embodiment, by setting up an air intake chamber, when the airflow moves at high speed in the flow chamber, the air pressure difference causes the air intake chamber to generate suction, which will then absorb the exhaust gas into its own interior and then transport it to a suitable location.

[0042] Specifically, the bearing cylinder 703 has an installation cavity inside, and the inside of the installation cavity is fixedly connected to the outer wall of the flow tube 704.

[0043] In this embodiment, by providing an installation cavity, the flow tube 704 can be installed at the position where it needs to work during the operation.

[0044] Specifically, an exhaust chamber is opened inside the flow tube 704, the inside of the exhaust chamber is sleeved with the outer wall of the fixing rod 706, and the top of the exhaust chamber is connected to the conveying chamber.

[0045] In this embodiment, by setting an exhaust chamber, the filtered exhaust gas can be transported into the interior of the extruder 5, which can preheat the material and thus improve the efficiency of use.
