Description

Technical Field

[0001] This invention relates to the field of pipeline manufacturing technology, specifically a drying device for pipeline manufacturing. Background Technology

[0002] A pipeline is a system of pipes, pipe fittings, valves, and other components used to transport gases, liquids, or fluids containing solid particles. Typically, fluids are pressurized by blowers, compressors, pumps, and boilers, flowing from high-pressure areas to low-pressure areas within the pipeline. Alternatively, the fluid's own pressure or gravity can be used for transport. Pipelines have a wide range of applications, primarily in water supply, drainage, heating, gas supply, long-distance transport of oil and natural gas, agricultural irrigation, water conservancy projects, and various industrial installations.

[0003] The prior art discloses a drying device for pipeline production, with publication number CN213454682U. The device includes: a drying chamber, a feeding trough, heating plates, a jet pipe, an air inlet pipe, an air heater, a power pump, a three-way valve, a circulation pipe, an air delivery pipe, and connecting holes. The top of the drying chamber is connected to the feeding trough. Several heating plates are installed inside the drying chamber. The heating plates and the side walls of the drying chamber are configured as a connected cavity structure. A jet pipe is installed on the lower part of the cavity side wall of the drying chamber. Air outlet holes are evenly distributed on the upper wall of the jet pipe. The jet pipe is connected to the air inlet pipe, which is equipped with an air heater and a power pump. The air inlet pipe is connected to the three-way valve and, through the three-way valve, to the circulation pipe and the air delivery pipe. One end of the circulation pipe is connected to the upper part of the cavity side wall of the drying chamber. Connecting holes are evenly distributed on the heating plates. This facilitates the drying of raw materials for pipeline production.

[0004] However, the aforementioned drying device for pipeline production uses a drying chamber and an air heater to generate hot air for drying. This method, which relies solely on hot air to enter and fill the entire drying chamber, requires an excessively long drying time. Furthermore, the drying effect is poor at the end furthest from the air inlet, resulting in uneven drying. Therefore, it is necessary to design a more practical and comprehensive drying device for pipeline production. Summary of the Invention

[0005] The purpose of this invention is to provide a drying apparatus for pipeline production to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a drying device for pipe production, comprising a processing cylinder, a sealed top cover being provided on the top of the processing cylinder, an adjusting rotation device being provided at the bottom of the processing cylinder, a drying device being provided at the top of the adjusting rotation device, and a pipe clamping device being provided at the top of the adjusting rotation device.

[0007] The pipe clamping device includes a placement cylinder, a hot gas inlet hole, a connecting spring, a semi-circular auxiliary fixing ring, a connecting soft rubber ball, a first heat-resistant rubber strip, a second anti-slip textured heat-resistant rubber block, and a second heat-resistant rubber strip. The hot gas inlet hole is located on the back of the placement cylinder. The connecting spring is fixedly connected to the inner wall of the placement cylinder. The semi-circular auxiliary fixing ring is fixedly connected to the end of the connecting spring away from the inner wall of the placement cylinder. The connecting soft rubber ball is fixedly connected to... The inner wall of the semi-circular auxiliary fixing ring frame is fixedly connected to the left back end of the first heat-resistant rubber strip block, the first anti-slip textured heat-resistant rubber block is fixedly connected to the surface of the first heat-resistant rubber strip block, the right back end of the second heat-resistant rubber strip block is fixedly connected to the inner wall of the semi-circular auxiliary fixing ring frame, the left back end of the second heat-resistant rubber strip block is fixedly connected to the surface of the connecting soft rubber ball, and the second anti-slip textured heat-resistant rubber block is fixedly connected to the surface of the second heat-resistant rubber strip block.

[0008] According to the above technical solution, the drying device includes a dryer, a hot air duct, a top connecting frame, a heating drying cylinder, a heat inlet hole, a duct placement ring, and a top connecting block. The dryer is fixedly connected to the right side of the processing cylinder, the hot air duct is fixedly connected to the left side of the dryer, the top connecting frame is fixedly connected to the inner wall of the processing cylinder near the top, the top connecting block is fixedly connected to the bottom of the top connecting frame, the heating drying cylinder is fixedly connected to the bottom of the top connecting block, the heat inlet hole is opened inside the heating drying cylinder, the duct placement ring is fixedly connected to the surface of the heating drying cylinder, and a vent is opened inside the hot air duct. The vent and the hot air inlet hole have the same diameter. By providing a vent and a hot air inlet hole with the same diameter, hot air can enter to facilitate drying of the duct.

[0009] According to the above technical solution, the adjusting rotation device includes a bottom mounting frame, a driving stepper motor, a connecting plate, and a placement plate. The bottom mounting frame is fixedly connected to the bottom of the processing cylinder, the driving stepper motor is fixedly connected to the top of the bottom mounting frame, the connecting plate is fixedly connected to the output shaft of the driving stepper motor, and the placement plate is fixedly connected to the top of the connecting plate.

[0010] According to the above technical solution, the top of the processing cylinder is provided with a docking groove, and the bottom of the sealed top cover is provided with a docking post. The docking post is adapted to the size of the docking groove, and the docking post is inserted into the inside of the docking groove. By providing the docking post and the docking groove, it is convenient for the sealed top cover to be inserted into the top of the processing cylinder, and the two are connected by a plug-in method, which makes it convenient to remove the sealed top cover to place the pipe.

[0011] According to the above technical solution, the end of the first heat-resistant rubber strip block away from the inner wall of the semi-circular auxiliary fixing ring is fixedly connected to the surface of the connecting soft rubber sphere.

[0012] According to the above technical solution, the number of the connecting spring, the semi-circular auxiliary fixing ring, the connecting soft rubber ball, the first heat-resistant rubber strip block, the second anti-slip textured heat-resistant rubber block, the second heat-resistant rubber strip block, and the first anti-slip textured heat-resistant rubber block are all in two sets. The two sets of the connecting spring, the semi-circular auxiliary fixing ring, the connecting soft rubber ball, the first heat-resistant rubber strip block, the second anti-slip textured heat-resistant rubber block, the second heat-resistant rubber strip block, and the first anti-slip textured heat-resistant rubber block are symmetrically distributed at the front and rear ends inside the placement cylinder. By setting two sets at the front and rear ends, the pipe can be clamped and has a certain adjustment capability, which can adapt to the placement of different types of pipes and facilitate the three-dimensional placement of pipes.

[0013] According to the above technical solution, the heat inlet holes are arranged in a ring at equal intervals inside the heating and drying cylinder. By providing heat inlet holes, they can be connected and aligned with the ventilation holes. The top of the hot air pipe can be inserted into the placement cylinder. After the hot air enters the hot air pipe, it can gradually enter the placement cylinder through the hot air inlet hole and the ventilation hole, which can dry the pipe placed in the placement cylinder.

[0014] According to the above technical solution, the diameter of the heat inlet hole is smaller than the distance between two adjacent pipe placement rings. The distance between two adjacent pipe placement rings is adapted to the diameter of the hot air pipe. By setting the pipe placement rings, the hot air pipe can be placed so that hot air can be input accordingly, which is convenient for heating and drying.

[0015] According to the above technical solution, the placement cylinder is fixedly connected to the top of the placement plate, and the bottom of the connecting plate is slidably connected to the inner bottom of the processing cylinder. By setting the placement plate, the placement cylinder can be placed and rotated synchronously when rotating, and the pipe also rotates synchronously. This can avoid the situation where the drying effect is poor at the end far from the air inlet, and can make the drying effect better.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] 1. The present invention is provided with a drying device that dries the pipes placed in the placement cylinder. When hot air enters, it does not need to diffuse to the entire heating and drying cylinder, but only needs to enter the placement cylinder. The time required for hot air diffusion is short, and the required drying time is short.

[0018] 2. This invention, by providing an adjustment and rotation device, can start the stepper motor during use. The output shaft of the stepper motor rotates, which can drive the connecting plate and the placement plate on top to rotate, and drive the placement cylinder to rotate synchronously. The pipe also rotates synchronously, thereby avoiding poor drying effect at the end far from the air inlet, and preventing uneven drying. The drying is comprehensive and efficient.

[0019] 3. This invention, by incorporating a pipe clamping device, allows the pipe to be placed against the first and second heat-resistant rubber strips on one side of the cylinder during installation. The pipe is then inserted so that its other end contacts the first and second heat-resistant rubber strips on the other side. After the pipe is inserted, the thrust disappears, and the connecting spring no longer rebounds. This, combined with the first and second heat-resistant rubber strips and their surface-mounted second anti-slip textured heat-resistant rubber blocks and structures, forms a clamping mechanism, completing the pipe placement. Furthermore, this device has a certain degree of adjustability, adapting to the placement of different pipe models.

[0020] 4. In this invention, by providing a sealed top cover, during installation, the sealed top cover can be pulled upwards to remove the bottom connecting post of the sealed top cover from the connecting groove, so that the sealed top cover is no longer in contact with the top of the processing cylinder. The sealed top cover can then be removed to expose the top of the processing cylinder, making it convenient to install the pipe. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-6 The present invention provides a technical solution: a drying device for pipe production, comprising a processing cylinder 1, a sealed top cover 5 at the top of the processing cylinder 1, an adjusting and rotating device 2 at the bottom of the processing cylinder 1, a drying device 3 at the top of the adjusting and rotating device 2, and a pipe clamping device 4 at the top of the adjusting and rotating device 2. A docking groove is provided at the top of the processing cylinder 1, and a docking post is provided at the bottom of the sealed top cover 5. The size of the docking post is adapted to the docking groove, and the docking post is inserted into the inside of the docking groove. By providing the docking post and the docking groove, it is convenient for the sealed top cover 5 to be inserted into the top of the processing cylinder 1, and the two are connected by a plug-in method, which makes it convenient to remove the sealed top cover 5 to place the pipe.

[0031] The pipe clamping device 4 includes a placement cylinder 401, a hot air inlet hole 402, a connecting spring 403, a semi-circular auxiliary fixing ring 404, a connecting soft rubber ball 405, a first heat-resistant rubber strip block 406, a second anti-slip textured heat-resistant rubber block 407, a second heat-resistant rubber strip block 408, and a first anti-slip textured heat-resistant rubber block 409. The hot air inlet hole 402 is located on the back of the placement cylinder 401. The connecting spring 403 is fixedly connected to the inner wall of the placement cylinder 401. The semi-circular auxiliary fixing ring 404 is fixedly connected to the end of the connecting spring 403 away from the inner wall of the placement cylinder 401. The connecting soft rubber ball 405 is fixedly connected to the semi-circular auxiliary fixing ring 404. The inner wall of the first heat-resistant rubber strip 406 is fixedly connected to the inner wall of the semi-circular auxiliary fixing ring 404 at its left rear end; the first anti-slip textured heat-resistant rubber block 409 is fixedly connected to the surface of the first heat-resistant rubber strip 406; the back right end of the second heat-resistant rubber strip 408 is fixedly connected to the inner wall of the semi-circular auxiliary fixing ring 404; the back left end of the second heat-resistant rubber strip 408 is fixedly connected to the surface of the connecting soft rubber ball 405; the second anti-slip textured heat-resistant rubber block 407 is fixedly connected to the surface of the second heat-resistant rubber strip 408; the placement cylinder 401 is fixedly connected to the top of the placement plate 204; and the bottom of the connecting plate 203 is slidably connected to the processing cylinder 1. The bottom is equipped with a placement tray 204 to hold the placement cylinder 401. When the tray rotates, it drives the placement cylinder 401 to rotate synchronously, and the pipe also rotates synchronously. This avoids the situation where the drying effect is poor at the end far from the air inlet, resulting in better drying. The end of the first heat-resistant rubber strip 406 away from the inner wall of the semi-circular auxiliary fixing ring 404 is fixedly connected to the surface of the connecting soft rubber ball 405. The connecting spring 403, the semi-circular auxiliary fixing ring 404, the connecting soft rubber ball 405, the first heat-resistant rubber strip 406, the second anti-slip textured heat-resistant rubber block 407, the second heat-resistant rubber strip 408, and the first anti-slip textured heat-resistant rubber... There are two sets of rubber blocks 409. The two sets of connecting springs 403, semi-circular auxiliary fixing rings 404, connecting soft rubber balls 405, first heat-resistant rubber strips 406, second anti-slip textured heat-resistant rubber blocks 407 and 408, and first anti-slip textured heat-resistant rubber blocks 409 are symmetrically distributed at the front and rear ends inside the placement cylinder 401. By setting two sets at the front and rear ends, the pipe can be clamped and has a certain degree of adjustment, which can be adapted to the placement of different types of pipes and facilitates the three-dimensional placement of pipes. By setting vent holes and hot air inlet holes 402, and the diameters of the two holes are equal, hot air can be introduced to help dry the pipe.

[0032] The drying device 3 includes a dryer 301, a hot air duct 302, a top connecting frame 303, a heating drying cylinder 304, a heat inlet hole 305, a duct placement ring 306, and a top connecting block 307. The dryer 301 is fixedly connected to the right side of the processing cylinder 1, the hot air duct 302 is fixedly connected to the left side of the dryer 301, the top connecting frame 303 is fixedly connected to the inner wall of the processing cylinder 1 near the top, the top connecting block 307 is fixedly connected to the bottom of the top connecting frame 303, the heating drying cylinder 304 is fixedly connected to the bottom of the top connecting block 307, the heat inlet hole 305 is opened inside the heating drying cylinder 304, the duct placement ring 306 is fixedly connected to the surface of the heating drying cylinder 304, and a vent is opened inside the hot air duct 302, through which hot air enters the cylinder. The holes 402 have equal diameters, and the heat inlet holes 305 are arranged in a ring at equal intervals inside the heating and drying cylinder 304. By providing the heat inlet holes 305, they can be connected and aligned with the vent holes. The top of the hot air pipe 302 can be inserted into the placement cylinder 401. After the hot air enters the hot air pipe 302, it can gradually enter the placement cylinder 401 through the hot air inlet holes 402 and the vent holes. The pipes placed in the placement cylinder 401 can be dried. The diameter of the heat inlet holes 305 is smaller than the distance between two adjacent pipe placement rings 306. The distance between two adjacent pipe placement rings 306 is adapted to the diameter of the hot air pipe 302. By providing the pipe placement rings 306, the hot air pipe 302 can be placed so that it can be correspondingly input with hot air, which is convenient for heating and drying.

[0033] The adjusting rotation device 2 includes a bottom mounting frame 201, a drive stepper motor 202, a connecting plate 203, and a placement plate 204. The bottom mounting frame 201 is fixedly connected to the bottom of the processing cylinder 1, the drive stepper motor 202 is fixedly connected to the top of the bottom mounting frame 201, the connecting plate 203 is fixedly connected to the output shaft of the drive stepper motor 202, and the placement plate 204 is fixedly connected to the top of the connecting plate 203.

[0034] When using the equipment, first place the pipes that need to be dried. During placement, pull the sealed top cover 5 upwards to remove the bottom connecting post from the connecting groove, ensuring the sealed top cover 5 is no longer in contact with the top of the processing cylinder 1. Remove the sealed top cover 5, exposing the top of the processing cylinder 1 for easy pipe placement. When placing the pipes, first place them against the first heat-resistant rubber strip block 406 and the second heat-resistant rubber strip block 408 on one side inside the cylinder 401. Since the first heat-resistant rubber strip block 406 and the second heat-resistant rubber strip block 408 are connected to form a V-shaped connecting block, and the connection is made by a soft rubber ball 405, the pipes can be placed against the first heat-resistant rubber strip block... The first heat-resistant rubber strip 406 and the second heat-resistant rubber strip 408 are slightly pushed a short distance, causing them to indent and compress the connecting spring 403. Then, the pipe can be inserted, so that the other end of the pipe contacts the first heat-resistant rubber strip 406 and the second heat-resistant rubber strip 408 on the other side. After the pipe is inserted, the pushing force disappears, and the connecting spring 403 no longer rebounds under force. Together with the first heat-resistant rubber strip 406 and the second heat-resistant rubber strip 408, and the second anti-slip textured heat-resistant rubber block 407 and the first anti-slip textured heat-resistant rubber block 409 on their surfaces, a clamping structure is formed, completing the placement of the pipe and providing a... With a certain adjustment capability, it can adapt to the placement of different types of pipes. Hot air is generated by starting the dryer 301 and transported into the hot air pipe 302. Before drying, the hot air pipe 302 needs to be wound around the surface of the heating and drying cylinder 304. During winding, the hot air pipe 302 is placed between two adjacent pipe placement rings 306, and the vent of the hot air pipe 302 is aligned with the heat inlet hole 305 on the surface of the heating and drying cylinder 304. Alternatively, the top end of the hot air pipe 302 can be inserted into the placement cylinder 401. After entering the hot air pipe 302, the hot air gradually enters the placement cylinder 401 through the hot air inlet hole 402 and the vent. The pipes are placed in the middle for drying, and when hot air enters, it does not need to diffuse into the entire heating and drying cylinder 304, but only needs to enter the placement cylinder 401. The time required for hot air diffusion is short, and the required drying time is short. Since the placement cylinder 401 is fixedly connected to the top of the placement plate 204, the stepper motor 202 can be started during use. The output shaft of the stepper motor 202 rotates, which drives the connecting plate 203 and the placement plate 204 on top to rotate, which drives the placement cylinder 401 to rotate synchronously. The pipes also rotate synchronously, which can avoid the end far from the air inlet having poor drying effect and uneven drying. The drying is comprehensive and efficient.
