Description

Technical Field

[0001] This utility model relates to a plastic extruder, specifically a novel energy-saving dual-purpose dry and wet heat-conducting oil plasticizing extruder, belonging to the technical field of plastic extruders. Background Technology

[0002] Plastic extruders are core equipment in the plastics processing industry, widely used in the production of plastic products such as pipes, profiles, films, and wires and cables. Dual-purpose extruders, capable of processing both dry and wet materials, meet diverse production needs. The application of heat transfer oil heating technology effectively improves the quality of plasticizing through uniform and stable heat transfer. In actual operation, the heat transfer oil circulates within the heat exchange jacket to achieve heat exchange, providing a stable heat source for the plasticizing process.

[0003] However, the heat exchange jackets of traditional dry and wet dual-purpose thermal oil extruders mostly adopt an integral closed structure. As the equipment operates for a long time, impurities, additives and oxidation products generated at high temperatures in the thermal oil will gradually adhere to the inner wall of the heat exchange jacket and form oil stains. These oil stains are like a heat insulation layer, which significantly reduces the heat transfer efficiency and causes a significant drop in heating performance. Utility Model Content

[0004] The purpose of this invention is to provide a new type of energy-saving, dry and wet dual-purpose heat-conducting oil plasticizing extruder to solve the above problems. When oil sludge forms inside the heat exchange jacket, the baffle can be quickly removed from the heat exchange jacket, and then the oil sludge inside the heat exchange jacket can be cleaned to avoid the oil sludge reducing the heat transfer efficiency, thereby effectively ensuring the heating effect.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: a novel energy-saving dual-purpose dry and wet heat-conducting oil plasticizing extruder, comprising an extruder body, a heating structure on the extruder body, the heating structure including heat exchange jackets and baffles, multiple heat exchange jackets fixedly connected to the extruder body, the heat exchange jackets having a fixing structure, two baffles engaging on the heat exchange jackets, multiple short pipes fixedly connected to the heat exchange jackets, one end of multiple short pipes located on one side of the heat exchange jackets being fixedly connected to the same second horizontal pipe, one end of multiple short pipes located on the other side of the heat exchange jackets being fixedly connected to the same first horizontal pipe, an oil inlet pipe fixedly connected to the first horizontal pipe, and an extrusion screw installed inside the extruder body.

[0006] Preferably, the two baffles are symmetrically distributed about the middle of the heat exchange jacket, and the baffles are provided with openings.

[0007] Preferably, the fixing structure includes connecting blocks and connecting plates. Two connecting blocks are fixedly connected to both sides of the heat exchange jacket, and one connecting plate is slidably connected to one of the two connecting blocks, while the other connecting plate is slidably connected to the other two connecting blocks.

[0008] Preferably, a screw is threadedly connected to the connecting plate, and a stop plate is rotatably connected to one end of the screw, with the stop plate abutting against the baffle.

[0009] Preferably, a rotating rod is fixedly connected to the other end of the screw, and the rotating rod is perpendicular to the screw.

[0010] Preferably, a locking block is slidably connected to the connecting plate, and one end of the locking block engages with the connecting block.

[0011] Preferably, a spring is sleeved on the outside of the card block, one end of the spring is fixedly connected to the card block, and the other end of the card block is fixedly connected to the connecting plate.

[0012] Preferably, the cross-section of the card block near the connecting block is trapezoidal, and the cross-section of the other end of the card block is T-shaped.

[0013] Preferably, the first horizontal tube is provided with a filter structure, the filter structure including a protrusion and a stop block, the first horizontal tube is threadedly connected to the stop block, one end of the stop block abuts against one end of the filter screen, the other end of the filter screen abuts against the first horizontal tube, and the other end of the stop block is fixedly connected to the protrusion.

[0014] The beneficial effects of this utility model are as follows: During use, the heat transfer oil circulation pipe can be connected to the oil inlet pipe and the second horizontal pipe respectively. Then, the heat transfer oil flows from the oil inlet pipe into the interior of the first horizontal pipe, and then enters the interior of the heat exchange jacket from the short pipe. When the heat exchange jacket is full of heat transfer oil, the heat transfer oil will flow from the short pipe into the interior of the second horizontal pipe, and finally flow out from the second horizontal pipe, thereby realizing the circulation of heat transfer oil. When oil scale appears inside the heat exchange jacket, the fixing structure can be used to quickly release the baffle, and then the baffle can be removed from the heat exchange jacket. After the baffle is removed, it will not block the heat exchange jacket, thus facilitating the cleaning of oil scale inside the heat exchange jacket, avoiding the oil scale from reducing the heat transfer efficiency, and thus effectively ensuring the heating effect.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-7 As shown, a novel energy-saving dual-purpose dry and wet heat-conducting oil plasticizing extruder includes an extruder body 1. The extruder body 1 is characterized by a heating structure 2, which includes a heat exchange jacket 201 and baffles 202. Multiple heat exchange jackets 201 are fixedly connected to the extruder body 1. A fixing structure 3 is provided on each heat exchange jacket 201. Two baffles 202 are engaged on each heat exchange jacket 201. Multiple short pipes 203 are fixedly connected to each heat exchange jacket 201. One end of one of the short pipes 203 on one side of the heat exchange jacket 201 is fixedly connected to the same second horizontal pipe 206, and one end of the other short pipes 203 on the other side of the heat exchange jacket 201 is fixedly connected to the same first horizontal pipe 204. An oil inlet pipe 205 is fixedly connected to the first horizontal pipe 204. An extrusion screw 5 is installed inside the extruder body 1.

[0025] As a technical optimization of this utility model, the two baffles 202 are symmetrically distributed about the middle of the heat exchange sleeve 201. The baffles 202 are provided with openings 207, so that a screwdriver can be inserted into the openings 207, thereby making it easy to pry the baffles 202 off the heat exchange sleeve 201.

[0026] As a technical optimization of this utility model, the fixing structure 3 includes a connecting block 301 and a connecting plate 302. Two connecting blocks 301 are fixedly connected to both sides of the heat exchange sleeve 201. The connecting blocks 301 can limit the position of the connecting plate 302. One of the connecting plates 302 is slidably connected to the two connecting blocks 301, and the other connecting plate 302 is slidably connected to the other two connecting blocks 301. When the connecting plate 302 and the connecting block 301 are separated, the connecting plate 302 can be removed from one side of the heat exchange sleeve 201, thereby avoiding the connecting plate 302 from obstructing the operator's body during the cleaning process.

[0027] As a technical optimization of this utility model, a screw 304 is threadedly connected to the connecting plate 302. By rotating the screw 304, the abutment 305 and the baffle 202 can be pressed together, thereby fixing the baffle 202 and the heat exchange jacket 201. One end of the screw 304 is rotatably connected to the abutment 305. The abutment 305 can increase the contact area with the baffle 202, thereby improving the fixing effect. The abutment 305 and the baffle 202 are in contact.

[0028] As a technical optimization of this utility model, the other end of the screw 304 is fixedly connected to a rotating rod 303, which is perpendicular to the screw 304. The screw 304 can be easily rotated by holding the rotating rod 303.

[0029] As a technical optimization of this utility model, a locking block 306 is slidably connected to the connecting plate 302, and the connecting plate 302 can be positioned by the locking block 306 engaging with the connecting block 301.

[0030] As a technical optimization of this utility model, a spring 307 is sleeved on the outside of the locking block 306. One end of the spring 307 is fixedly connected to the locking block 306, and the other end of the locking block 306 is fixedly connected to the connecting plate 302. Under the action of the spring 307, the locking block 306 and the connecting block 301 can be locked more stably.

[0031] As a technical optimization of this utility model, the cross-section of the locking block 306 near the connecting block 301 is trapezoidal, so it can play a guiding role when the locking block 306 and the connecting block 301 are engaged. The cross-section of the other end of the locking block 306 is T-shaped, so the locking block 306 can be pulled easily.

[0032] As a technical optimization of this utility model, a filter structure 4 is provided on the first horizontal tube 204. The filter structure 4 includes a protrusion 401 and a stop 402. The stop 402 is threadedly connected to the first horizontal tube 204, so the filter screen 403 can be fixed by the contact between the stop 402 and the filter screen 403. One end of the stop 402 contacts one end of the filter screen 403, and the other end of the filter screen 403 contacts the first horizontal tube 204. Therefore, the heat transfer oil can be filtered by the filter screen 403 to prevent large particles of impurities from entering the interior of the heat exchange jacket 201. The other end of the stop 402 is fixedly connected to the protrusion 401, so the stop 402 can be rotated by holding the protrusion 401.

[0033] In use, this invention connects the heat transfer oil circulation pipe to the inlet pipe 205 and the second horizontal pipe 206, allowing the heat transfer oil to flow from the inlet pipe 205 into the first horizontal pipe 204. During this flow, the heat transfer oil passes through the filter screen 403 to filter out large particles, preventing them from entering the heat exchanger jacket 201 and the first horizontal pipe 204. The heat transfer oil enters the heat exchanger 201 through the short pipe 203. Once the heat exchanger 201 is full of heat transfer oil, it flows from the short pipe 203 into the second horizontal pipe 206 and finally out of the second horizontal pipe 206, thus achieving the circulation of the heat transfer oil. When oil deposits appear inside the heat exchanger 201, the screw 304 can be rotated by holding the lever 303. During rotation, the screw 304 will cause the abutment plate 305 to move away from the baffle 202. Rotating both screws 304 in sequence causes the two abutments 305 to move away from the baffle 202. Maintain a certain distance between the baffle 202 and the baffle plate 202, then pull the locking block 306. The spring 307 extends. When one end of the locking block 306 is no longer engaged with the connecting block 301, push the connecting plate 302 to disengage it from the two connecting blocks 301. Then, the connecting plate 302 can be removed from one side of the baffle 202. Finally, insert a flathead screwdriver into the opening 207 to pry the baffle 202 off the heat exchange jacket 201, thus achieving quick disassembly of the baffle 202. After the baffle 202 is removed... The heat exchange jacket 201 is not blocked, which facilitates the cleaning of oil stains inside the heat exchange jacket 201 and avoids the oil stains reducing the heat transfer efficiency, thus effectively ensuring the heating effect. When it is necessary to clean the filter screen 403, the block 402 can be twisted off the first horizontal tube 204 by holding the protrusion 401, and then the filter screen 403 can be removed from the inside of the first horizontal tube 204, which facilitates the cleaning of the filter screen 403, avoids the filter screen 403 from becoming blocked, and effectively ensures the filtration effect.
