Abstract
Description
Technical Field
[0001] This invention relates to the field of corrugated pipe processing and production technology, and in particular to a corrugated pipe production equipment with high heat exchange efficiency. Background Technology
[0002] Corrugated pipe is a general term for metal bellows, corrugated expansion joints, corrugated heat exchange tubes, diaphragm boxes, and metal flexible hoses. It serves to compensate for pipeline thermal deformation, reduce vibration, and absorb pipeline settlement deformation, and is widely used in industries such as petrochemicals, instrumentation, aerospace, chemicals, power, and cement.
[0003] In the current corrugated pipe manufacturing process, the main method is to produce it by integral casting. This requires the raw materials to be fed into the molding device through a pipe using an extruder in advance. This not only results in a long extrusion stroke but also a large structural footprint. The heat generated during the molding process cannot be recovered and utilized, leading to significant energy loss. At the same time, a large cooling stroke is required, resulting in low equipment molding efficiency. Summary of the Invention
[0004] The technical problem to be solved by the present invention is that the integrated casting molding device currently used for producing corrugated pipes not only has a long extrusion stroke, but also occupies a large area of the structure. The heat generated during the molding process cannot be recovered and utilized, resulting in serious energy loss. At the same time, it requires a large cooling stroke, resulting in low molding efficiency of the equipment.
[0005] The technical solution adopted by the present invention to solve its technical problem is: a corrugated pipe production equipment with high heat exchange effect, including a bottom main frame, a horizontal top extruder fixedly mounted on the upper end of the bottom main frame, side guide wheels movably mounted on both sides of the inner bottom surface of the bottom main frame, a transverse conveyor belt movably sleeved on the outer side of the side guide wheels, a detachable corrugated pipe side forming block with an internal forming groove installed on the outer side of the transverse conveyor belt, and a bottom drive device that cooperates with the detachable corrugated pipe side forming block is installed at the middle position of the inner bottom surface of the bottom main frame.
[0006] The horizontal top extruder has a strip-shaped top guide and limiting groove on its lower surface above the detachable corrugated pipe side forming block. A top feeding port connected to the bottom discharge port of the horizontal top extruder is provided on one side of the top surface of the strip-shaped top guide and limiting groove. A top feeding channel connected to the internal forming groove is provided at the upper end of the detachable corrugated pipe side forming block.
[0007] A lateral assembly block with outward protrusion is fixed on the outer surface of the transverse conveyor belt. The detachable corrugated pipe lateral forming block is fixedly assembled with the transverse conveyor belt on the outside of the lateral assembly block through the lateral assembly groove on the connecting surface.
[0008] The bottom drive device includes a bottom assembly frame fixed in the middle of the top surface inside the bottom main frame, a bottom support wheel movably assembled inside the bottom assembly frame, a bottom drive wheel, a flexible conveyor belt sleeved on the outside of the bottom support wheel and the bottom drive wheel, inclined assembly surfaces opened on both sides of the flexible conveyor belt, and a lateral drive head fixed on the inclined assembly surface.
[0009] The detachable corrugated pipe side forming block assembly surface has a bottom driving hole that cooperates with the side driving head.
[0010] The bottom of the main frame is fixedly fitted with bottom-mounted cooling water tanks on both sides of the bottom assembly frame. The bottom support liquid guide pipe, which is connected to the inside of the bottom-mounted cooling water tank, is fixedly fitted inside the bottom assembly frame on the inside of the flexible conveyor belt.
[0011] The detachable corrugated pipe lateral forming block has an internal cooling channel that communicates with the lateral drive head located outside the internal forming groove.
[0012] The height of the bottom surface inside the bottom assembly frame gradually decreases with the conveying direction of the bottom drive device, and a return pipe connected to the inside of the bottom-mounted cooling water tank is fixed at the lower end of the outer side of the bottom assembly frame.
[0013] A horizontally placed guide assembly tube is fixed to the inner side of the bottom main frame, and an electrically controlled telescopic central forming tube is slidably sleeved on the outer side of the horizontally placed guide assembly tube.
[0014] The beneficial effects of this invention are:
[0015] (1) The corrugated pipe production equipment with high heat exchange effect of the present invention installs a horizontal top extruder on the bottom main frame and then installs the corrugated pipe forming equipment inside, thereby greatly improving the space utilization of the entire equipment by utilizing the longitudinal space.
[0016] (2) By installing a bottom drive device that cooperates with the detachable corrugated pipe side forming block in the middle of the bottom surface of the bottom main frame, the driving method is simpler and the linkage is greatly enhanced.
[0017] By installing the molding equipment directly below the horizontal overhead extruder, the heat emitted by the molding machine can be greatly utilized, improving the heat exchange effect and reducing energy consumption.
[0018] (4) The lateral drive heads on the inclined assembly surfaces on both sides of the flexible conveyor belt can not only control the detachable corrugated pipe lateral forming blocks on both sides, but also improve the fit and increase the forming effect by utilizing the inclined surfaces.
[0019] (5) By using the bottom-mounted cooling water tank located inside the bottom main frame, the water can be quickly introduced into the internal cooling channel through the side drive head, which greatly improves the cooling and forming effect and reduces the cooling stroke.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0026] Figure 1 , Figure 2 and Figure 3 The corrugated pipe production equipment shown includes a bottom main frame 1, a horizontal top extruder 2 fixedly mounted on the upper end of the bottom main frame 1, side guide wheels movably mounted on both sides of the inner bottom surface of the bottom main frame 1, a horizontal conveyor belt 4 movably sleeved on the outer side of the side guide wheels, a detachable corrugated pipe side forming block 5 with an internal forming groove installed on the outer side of the horizontal conveyor belt 4, and a bottom drive device 6 that cooperates with the detachable corrugated pipe side forming block 5 is installed at the middle position of the inner bottom surface of the bottom main frame 1.
[0027] The horizontal overhead extruder 2 is existing technology, used to transport and mix raw materials, and finally introduce them into the interior of the detachable corrugated side forming block 5. Then, the heat from the top of the detachable corrugated side forming block 5 is introduced into the interior of the horizontal overhead extruder 2, and the heat is exchanged to the interior of the horizontal overhead extruder 2, thereby reducing the energy consumption inside the horizontal overhead extruder 2.
[0028] The horizontal conveyor belt 4 is set outside the side guide wheel to form a horizontal conveyor belt structure for driving the detachable corrugated pipe side forming block 5 to circulate.
[0029] A strip-shaped top guide and limiting groove 7 is provided on the lower surface of the horizontal top extruder 2 above the detachable corrugated tube side forming block 5. A top feeding port 8 connected to the bottom feeding port of the horizontal top extruder 2 is provided on one side of the top surface of the strip-shaped top guide and limiting groove 7. A top feeding channel 9 connected to the internal forming groove is provided at the upper end of the detachable corrugated tube side forming block 5.
[0030] To facilitate loading and unloading, a side assembly block 10 with outward protrusion is fixed on the outer side of the transverse conveyor belt 4. The detachable corrugated pipe side forming block 5 is fixedly assembled with the transverse conveyor belt 4 on the outside of the side assembly block 10 through the side assembly groove on the connecting surface.
[0031] The lower end of the side mounting groove on the mounting surface of the detachable corrugated pipe side forming block 5 is open, and the detachable corrugated pipe side forming block 5 is fitted onto the outside of the side mounting block 10 from top to bottom.
[0032] To cooperate with the bottom drive, the bottom drive device 6 includes a bottom assembly frame 61 fixed in the middle of the top surface of the bottom main frame 1, a bottom support wheel 62 movably assembled inside the bottom assembly frame 61, a bottom drive wheel 63, a flexible conveyor belt 64 sleeved on the outside of the bottom support wheel 62 and the bottom drive wheel 63, inclined assembly surfaces opened on both sides of the flexible conveyor belt 64, and a lateral drive head 65 fixed on the inclined assembly surface.
[0033] The bottom drive wheel 63 is movably mounted on one end of the bottom assembly frame 61 and a lateral drive motor fixed on the outside of the bottom assembly frame 61. The lateral drive motor is axially fixed to the drive wheel by inserting a lateral drive shaft into the drive wheel. The outer arc surface of the drive wheel has teeth, which can improve the anti-slip properties of the flexible conveyor belt 64.
[0034] In order to coordinate the synchronous driving of the detachable corrugated pipe side forming blocks on both sides, the mounting surface of the detachable corrugated pipe side forming block 5 is provided with a bottom driving hole 11 that cooperates with the side driving head 65.
[0035] When the bottom drive device 6 is driven, the side drive head 65 is inserted into the bottom drive hole 11, which will drive the detachable corrugated side forming blocks on both sides and the horizontal conveyor belt 4 to move synchronously.
[0036] To improve molding efficiency, bottom cooling water tanks 12 are fixedly installed on both sides of the bottom assembly frame 61 on the inner bottom surface of the bottom main frame 1. Bottom support liquid guide pipes 13, which are connected to the inside of the bottom cooling water tanks 12, are fixedly installed inside the bottom assembly frame 61 on the inner side of the flexible conveyor belt 64.
[0037] The bottom support liquid guide pipe 13 can work with the bottom support wheel 62 to support the flexible conveyor belt 64, ensuring the support stability of the flexible conveyor belt 64. The bottom support liquid guide pipe 13 is fixed on both sides of the bottom assembly frame 61 to improve the structural strength. One side is connected to the bottom-mounted cooling water tank 12 which is responsible for liquid supply.
[0038] In order to improve the cooling and forming effect and shorten the cooling stroke, the detachable corrugated pipe side forming block 5 has an internal cooling channel 14 that is connected to the side drive head 65 located outside the internal forming groove.
[0039] In order to facilitate the return and reuse of the internal coolant, the height of the bottom surface of the bottom assembly frame 61 gradually decreases with the conveying direction of the bottom drive device 6, and a return pipe 15 connected to the inside of the bottom-mounted cooling water tank 12 is fixed at the lower end of the outer side of the bottom assembly frame 61.
[0040] An existing electrically controlled water pump is installed inside the bottom-mounted cooling water tank 12. The water pump guides the coolant from the bottom-mounted cooling water tank 12 through the outlet hole on the bottom support guide pipe 13 into the flexible conveyor belt 64. Then, the coolant is guided into the internal cooling channel 14 by the lateral drive heads on both sides of the flexible conveyor belt 64. The coolant is then quickly absorbed by the heat outside the internal forming tank for final cooling. After cooling is completed, the flexible conveyor belt 64 continues to transport the coolant. The coolant inside the internal cooling channel 14 flows back into the bottom assembly frame 61 due to gravity, and finally falls back into the return pipe 15. Then, it flows back into the bottom-mounted cooling water tank 12 through the return pipe 15.
[0041] The bottom-mounted cooling water tanks 12 on both sides are used to supply coolant to the bottom support liquid guide pipe 13 on one side and to recover and filter coolant on the other side. The bottom-mounted cooling water tanks 12 on both sides are connected by a horizontal connecting pipe.
[0042] In order to adjust and control the molding stroke, a horizontal guide assembly tube 16 is fixed on the inner side of the bottom main frame 1, and an electrically controlled telescopic central molding tube 17 is slidably sleeved on the outer side of the horizontal guide assembly tube 16.
[0043] The electrically controlled telescopic central forming tube 17 is existing technology. It consists of a horizontal electrically controlled telescopic machine axially fixed inside the horizontal guide assembly tube 16 and an outer forming tube slidably sleeved on the outside of the horizontal guide assembly tube 16. The horizontal electrically controlled telescopic machine is coaxially assembled with the linkage shaft in the middle of the inner side of the outer forming tube through a telescopic rod on one side. The horizontal electrically controlled telescopic machine controls the sliding adjustment of the outer forming tube along the horizontal guide assembly tube 16 by telescopic extension.
[0044] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
