Description

Technical Field

[0001] This invention relates to the field of waste gas collection and treatment technology, specifically to a waste gas collector for a cable plastic sheath extruder. Background Technology

[0002] The exhaust gas collector for cable plastic sheath extruder is a device that can absorb the organic waste gas generated during the molding process of cable plastic sheath. When absorbing organic waste gas, it needs to be guided into a container containing water. The water absorbs the dust particles in the organic waste gas, and then activated carbon absorbs the non-methane total hydrocarbons in the organic waste gas.

[0003] Existing exhaust gas collectors for cable plastic sheath extruders cannot be quickly installed on the outside of the cable plastic sheath. For example, CN214552071U discloses an exhaust gas collection and treatment device for cable extruders, which uses a clamping bolt and other structures to fit the first and second sleeve units onto the outside of the cable plastic sheath. Since clamping bolts are used, tools are required for operation, and the process is relatively cumbersome.

[0004] In addition, the exhaust gas collector of the existing cable plastic sheath extruder cannot stir the water in the container, which leads to the inability to improve the efficiency and effect of the water absorption machine in removing dust particles from the exhaust gas.

[0005] Therefore, there is a need for an exhaust gas collector for cable plastic sheath extruders to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an exhaust gas collector for a cable plastic sheath extruder, in order to solve the problems mentioned in the background art, namely that the existing exhaust gas collectors for cable plastic sheath extruders cannot be conveniently and quickly fitted onto the outside of the cable plastic sheath, and cannot stir the water in the container, thus failing to guarantee the efficiency and effectiveness of water in absorbing dust particles.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A waste gas collector for a cable plastic sheath extruder includes a base and a control panel mounted thereon. A support column perpendicular to the base is fixed to the upper surface of the base, and the lower end of a support rod extends into the upper opening of the support column. A locking bolt is threaded through the upper side of the support column. A sliding support assembly is mounted on the upper end of the support rod, and a lower suction assembly is supported on the sliding support assembly. The lower suction assembly is connected to the upper suction assembly via a negative pressure adsorption connection mechanism. Each component is fixedly connected to an arc-shaped cavity tube. The lower and upper air intake components are connected to the corresponding arc-shaped cavity tubes through strip pipes. The upper surface of the base is also equipped with two symmetrical water tanks and an activated carbon tube. The arc-shaped cavity tubes are connected to the two water tanks through a negative pressure air intake and delivery mechanism. The two water tanks are connected to the lower end of the activated carbon tube through an air supply pipe. An exhaust nozzle is installed at the upper end of the activated carbon tube. A pneumatic stirring mechanism is installed inside the water tank, and the pneumatic stirring mechanism includes a stirring tube installed inside the water tank.

[0009] Preferably, the sliding support assembly consists of a slide rail and two sliders. The slide rail is supported on the upper end of the support rod, and the lower parts of the two sliders are slidably connected in the slide rail. The two sliders are two symmetrical L-shaped structures. The upper parts of the two sliders are respectively fixedly connected to the two ends of the lower air intake assembly. A protrusion is provided on the lower surface of the middle part of the lower air intake assembly, and the protrusion is fixedly connected to the middle part of the slide rail.

Both the lower and upper air intake components are provided with air intake holes and arc-shaped through holes that penetrate their inner and outer sides, wherein the arc-shaped through holes are located on the inner side of the trumpet-shaped end.

[0011] Preferably, the negative pressure adsorption connection mechanism includes a piston block and an inner tube that are both provided on the rigid arc-shaped tube plane of the lower air intake component and the upper air intake component. The lower air intake component and the upper air intake component are spliced ​​together by the seamless engagement of the piston block and the inner tube. A three-way tube is seamlessly provided through both the lower air intake component and the upper air intake component. One end of the three-way tube is connected through to the corresponding arc-shaped cavity tube, and the other two ends of the three-way tube are respectively connected through to two corresponding inner tubes.

[0012] Preferably, the portion of the tee tube within the flexible telescopic arc tube is wavy to prevent the tee tube from being torn apart during the stretching process of the flexible telescopic arc tube.

[0013] Preferably, the negative pressure suction conveying mechanism includes a motor mounted on the upper surface of the base, the motor being electrically connected to the control panel, a mounting bracket being fixedly connected to the base, and a reciprocating lead screw being connected to the mounting bracket and the base via a bearing. The reciprocating lead screw is connected to the output end of the motor via a belt drive assembly, and a synchronizing block is threaded onto the reciprocating lead screw.

[0014] Preferably, the negative pressure suction delivery mechanism further includes a piston tube installed above the base. The piston tube is supported on the upper surface of the base by two support columns. A piston plate is seamlessly slidably connected inside the piston tube, and a loop rod is provided through the piston tube. The loop rod is connected to the piston tube in a coaxial, seamless, sealed, and movable manner. The piston plate is coaxially and fixedly connected to the loop rod part inside the piston tube, and the part of the loop rod outside the piston tube is fixedly connected to the synchronization block.

[0015] Preferably, the negative pressure suction delivery mechanism further includes a one-way suction pipe with one end connected to the piston tube, and the other end of the one-way suction pipe is connected to the corresponding arc-shaped cavity tube. The two one-way suction pipes are respectively connected to the two ends of the piston tube, and the two ends of the piston tube are sealed and penetrate the two water tanks through the two one-way exhaust pipes respectively.

[0016] Preferably, the pneumatic stirring mechanism further includes a stirring frame fixed at an equal angle to the outside of the stirring tube. The lower end of the stirring tube is coaxially connected to the inner bottom surface of the corresponding water tank via a sealed bearing. A limiting square hole extending to the lower surface of the base is provided at the center of the inner bottom surface of the water tank. After the one-way exhaust pipe passes through the corresponding water tank in a sealed manner, it passes through the upper end of the corresponding stirring tube coaxially via a sealed bearing. A partition is provided inside the stirring tube. The piston end of a piston rod is seamlessly slidably connected inside the stirring tube, and the rod end of the piston rod passes through the partition in a sealed and movable manner. The piston rod has a drive disc coaxially connected to its rod end. The outer side of the drive disc and the inner side of the stirring tube are both provided with twisted threads, and the drive disc and the stirring tube are threadedly connected. A limiting square block coaxially connected to the lower surface of the drive disc is fixedly connected to it, and the lower end of the limiting square block extends into a limiting square hole that matches it. A spring for resetting the drive disc is provided between the lower surface of the drive disc and the inner bottom surface of the water tank. The stirring tube has one-way exhaust holes distributed at equal angles, and the one-way exhaust holes are located above the partition plate.

[0017] Preferably, the connection between the piston rod end and the drive disc is a bearing connection, and the thickness of the piston rod piston end is less than the minimum distance between the one-way exhaust hole and the partition.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the exhaust gas collector for cable plastic sheath extruder can quickly connect the lower and upper suction components and ensure the stability after connection. This allows for easy and quick installation of the exhaust gas collector on the outside of the cable plastic sheath. Furthermore, during the conveying of organic waste gas, the reciprocating rotation of the stirring tube facilitates the stirring of the water in the tank, thus improving the efficiency and effectiveness of dust particle absorption.

[0019] 1. The seamless sliding connection between the piston block and the recessed tube allows for the initial connection between the lower and upper air intake components. After the motor starts, it generates negative pressure in the arc-shaped cavity, which in turn generates negative pressure in the recessed tube through the three-way tube, thus ensuring a stable connection between the lower and upper air intake components. This makes it relatively easy to remove the upper air intake component from the lower air intake component when it is necessary to separate the lower and upper air intake components, simply by stopping the motor.

[0020] 2. After the motor starts, the organic waste gas is drawn into the stirring tube inside the water tank through the suction hole and arc-shaped through hole. The continuous influx of organic waste gas into the stirring tube increases the internal air pressure, which in turn pushes the piston rod to move. After the piston rod moves, the drive disc connected to it moves synchronously, which in turn drives the stirring tube to rotate until the organic waste gas entering the stirring tube can be discharged through the one-way exhaust hole. Then, the drive disc is reset by the spring. The intermittent influx of organic waste gas into the stirring tube and the spring cause the stirring tube to rotate back and forth, which makes the stirring frame agitate the water in the water tank, which helps to improve the efficiency and effect of absorbing dust particles.

[0036] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-14 The present invention provides the following technical solution:

[0038] Example 1: To address the problem of conventional exhaust gas collectors being inconvenient to quickly install on the outside of cable plastic sheaths, the following technical solution is provided: An exhaust gas collector for a cable plastic sheath extruder includes a base 1 and a control panel 2 mounted thereon. A support column 3 perpendicular to the base 1 is fixed to the upper surface of the base 1, and the lower end of a support rod 4 extends into the upper opening of the support column 3. A locking bolt 5 is threaded through the upper side of the support column 3, and a sliding support assembly is installed at the upper end of the support rod 4. Component 36, and the sliding support assembly 36 supports a lower suction assembly 6, which is connected to the upper suction assembly 7 via a negative pressure adsorption connection mechanism. Both the lower suction assembly 6 and the upper suction assembly 7 are fixedly connected to an arc-shaped cavity tube 8. Both the lower suction assembly 6 and the upper suction assembly 7 are connected to the corresponding arc-shaped cavity tube 8 via strip pipes. The upper surface of the base 1 is also equipped with two symmetrical water tanks 9 and an activated carbon tube 10. The arc-shaped cavity tube 8 is connected to the two water tanks 9 via a negative pressure suction delivery mechanism. The two water tanks 9 are connected to each other, and the two water tanks 9 are connected to the lower end of the activated carbon tube 10 through the air supply pipe 27. The upper end of the activated carbon tube 10 is equipped with an exhaust nozzle 28. The sliding support assembly 36 consists of a slide rail and two sliders. The slide rail is supported on the upper end of the support rod 4. The lower parts of the two sliders are slidably connected to the slide rail. The two sliders are two symmetrical L-shaped structures. The upper parts of the two sliders are respectively fixedly connected to the two ends of the lower air intake assembly 6. The lower surface of the middle part of the lower air intake assembly 6 is provided with a protrusion, which is fixedly connected to the slide rail. In the middle of the passage, both the lower air intake assembly 6 and the upper air intake assembly 7 are composed of three rigid arc-shaped tubes, and adjacent rigid arc-shaped tubes are connected by flexible telescopic arc-shaped tubes. Both the lower air intake assembly 6 and the upper air intake assembly 7 are hollow structures, and one end of the lower air intake assembly 6 and the upper air intake assembly 7 after splicing is trumpet-shaped. Both the lower air intake assembly 6 and the upper air intake assembly 7 are provided with air intake holes 11 and arc-shaped through holes 22 that penetrate their inner and outer sides, and the arc-shaped through holes 22 are located on the inner side of the trumpet-shaped end.

[0039] The negative pressure adsorption connection mechanism includes piston blocks 20 and recessed tubes 21, both of which are set on the rigid arc-shaped tube planes of the lower air intake component 6 and the upper air intake component 7. The lower air intake component 6 and the upper air intake component 7 are spliced ​​by the seamless engagement of the piston blocks 20 and the recessed tubes 21. A three-way tube 23 is seamlessly installed through both the lower air intake component 6 and the upper air intake component 7. One end of the three-way tube 23 is connected to the corresponding arc-shaped cavity tube 8, and the other two ends of the three-way tube 23 are respectively connected to the two corresponding recessed tubes 21. The part of the three-way tube 23 that is in the flexible telescopic arc-shaped tube is wavy to prevent the three-way tube 23 from being torn off during the stretching of the flexible telescopic arc-shaped tube.

[0040] according to Figures 3-11In use, the lower suction assembly 6 and the upper suction assembly 7 can be initially connected by connecting the piston block 20 and the recessed tube 21. Then, the negative pressure is generated in the arc-shaped cavity tube 8 by the negative pressure suction delivery mechanism.

[0041] The negative pressure generated inside the arc-shaped cavity tube 8 will not only cause negative pressure in the recessed tube 21 through the three-way tube 23, but also make the piston block 20 and the recessed tube 21 more tightly connected, thereby ensuring a stable connection between the lower suction assembly 6 and the upper suction assembly 7. When it is necessary to separate the lower suction assembly 6 and the upper suction assembly 7, it is only necessary to stop the operation of the negative pressure suction delivery mechanism, and the lower suction assembly 6 and the upper suction assembly 7 can be separated relatively easily.

[0042] Negative pressure is generated inside the arc-shaped cavity tube 8, and negative pressure can also be generated inside the lower suction component 6 or the upper suction component 7 through the strip pipe. At this time, the suction hole 11 and the arc-shaped through hole 22 will generate suction force, so as to draw the organic waste gas generated during the molding process of the cable plastic jacket into the lower suction component 6 or the upper suction component 7.

[0043] During the process, as the cable's plastic sheath is in the conveying state, the organic waste gas generated on its surface will be dispersed at an angle in the conveying direction, and can be quickly absorbed through the trumpet-shaped end and arc-shaped through hole 22 formed by the lower suction component 6 and the upper suction component 7.

[0044] The negative pressure suction delivery mechanism includes a motor 13 mounted on the upper surface of the base 1. The motor 13 is electrically connected to the control panel 2. A mounting bracket 16 is also fixedly connected to the base 1, and a reciprocating lead screw 15 is connected to the mounting bracket 16 and the base 1 via a bearing. The reciprocating lead screw 15 is connected to the output end of the motor 13 through a belt drive assembly 14, and a synchronizing block 18 is threaded onto the reciprocating lead screw 15. The negative pressure suction delivery mechanism also includes a piston tube 19 mounted above the base 1. The piston tube 19 is supported on the upper surface of the base 1 by two support columns. The piston tube 19 has a seamless sliding connection to the piston plate 25, and a loop rod 24 is provided through the piston tube 19. The loop rod 24 is connected to the piston tube 19 in a coaxial, seamless, sealed, and movable manner. The piston plate 25 is coaxially and fixedly connected to the loop rod 24 part inside the piston tube 19. The part of the loop rod 24 outside the piston tube 19 is fixedly connected to the synchronizing block 18. The negative pressure suction conveying mechanism also includes a one-way suction pipe 12 that is connected to the piston tube 19 at one end, and the other end of the one-way suction pipe 12 is connected to the corresponding arc-shaped cavity pipe 8. The two one-way suction pipes 12 are respectively connected to the two ends of the piston tube 19. The two ends of the piston tube 19 are respectively sealed and pass through the two water tanks 9 through two one-way exhaust pipes 26.

[0045] according to Figures 1-3 and Figure 12In use, motor 13 is started via control panel 2. After motor 13 starts, it will drive reciprocating screw 15 to rotate via belt drive assembly 14.

[0046] During the rotation of the reciprocating screw 15, the synchronizing block 18 moves along the axis of the reciprocating screw 15 due to the limiting effect of the piston tube 19 on the return rod 24.

[0047] When the synchronizing block 18 moves, the connecting rod 24 moves synchronously, thereby driving...

[0048] The piston plate 25 moves back and forth in the piston tube 19, thereby creating negative pressure alternately in the two arc-shaped chambers 8 through the one-way suction pipe 12, so as to absorb organic waste gas.

[0049] Organic waste gas enters water tank 9 through one-way exhaust pipe 26.

[0050] Example 2: To solve the problem that previous exhaust gas collectors could not disturb the water in the container, thus failing to improve the efficiency and effect of absorbing dust particles, the following technical solution is provided: Specifically, a pneumatic stirring mechanism is provided inside the water tank 9, and the pneumatic stirring mechanism includes a stirring pipe 29 installed inside the water tank 9.

[0051] The pneumatic stirring mechanism also includes a stirring frame 30 fixed at an equal angle to the outside of the stirring tube 29. The lower end of the stirring tube 29 is coaxially connected to the inner bottom surface of the corresponding water tank 9 via a sealed bearing. A limiting square hole 17 extending to the lower surface of the base 1 is provided at the center of the inner bottom surface of the water tank 9. After the one-way exhaust pipe 26 passes through the corresponding water tank 9 in a sealed manner, it passes through the upper end of the corresponding stirring tube 29 coaxially via a sealed bearing. A partition 31 is provided inside the stirring tube 29. The piston end of the piston rod 32 is seamlessly slidably connected inside the stirring tube 29. The rod end of the piston rod 32 passes through the partition 31 in a sealed and movable manner. A drive disc 33 is connected to the rod end of the piston rod 32 and is coaxial with it. Both the side and the inner side of the stirring tube 29 are provided with twisted threads, and the drive disc 33 is threadedly connected to the stirring tube 29. A limiting square block 34 coaxial with it is fixedly connected to the lower surface of the drive disc 33, and the lower end of the limiting square block 34 extends into the limiting square hole 17 that matches it. A spring for resetting the drive disc 33 is provided between the lower surface of the drive disc 33 and the inner bottom surface of the water tank 9. One-way exhaust holes 35 are opened on the stirring tube 29 at equal angles, and the one-way exhaust holes 35 are located above the partition plate 31. The connection between the rod end of the piston rod 32 and the drive disc 33 is a bearing connection, and the thickness of the piston end of the piston rod 32 is less than the minimum distance between the one-way exhaust hole 35 and the partition plate 31.

[0052] according to Figures 13-14Organic waste gas enters the stirring tube 29 in the water tank 9 through the one-way exhaust pipe 26, which increases the gas pressure in the stirring tube 29 and causes the piston rod 32 inside to move downward.

[0053] When the piston rod 32 moves downward, the drive disc 33 connected to it moves downward synchronously, and the limiting square block 34 connected to the drive disc 33 gradually moves into the limiting square hole 17 until the organic waste gas can be discharged from the stirring tube 29 through the one-way exhaust hole 35.

[0054] Since the limiting square block 34 and the limiting square hole 17 limit the drive disk 33, when the drive disk 33 moves down, it drives the stirring tube 29 to rotate. During the rotation of the stirring tube 29, the stirring frame 30 connected to it moves synchronously, thereby stirring the water in the water tank 9. By intermittently injecting organic waste gas into the stirring tube 29 and the spring set below the drive disk 33, the stirring tube 29 and the stirring frame 30 can rotate back and forth, which helps to improve the efficiency and effect of water in absorbing dust particles.

[0055] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
