Description

Technical Field

[0001] This utility model relates to the field of pipe manufacturing technology, and in particular to a raw material mixing device for the production of rigid polyvinyl chloride cable pipes. Background Technology

[0002] Pipes are the materials used to make pipe fittings. Different pipe fittings require different pipe materials, and the quality of the pipe material directly determines the quality of the pipe fittings. Pipes are widely used in construction projects, power plants, chemical plants, and many other industries. Electrical conduits are one type of pipe material. Electrical conduits are products made by hot-dip plastic coating of PE or epoxy resin coating both internally and externally, possessing excellent corrosion resistance. At the same time, the coating itself also has good electrical insulation properties, preventing electrolytic corrosion.

[0003] For example, Chinese utility model patent with announcement number CN220995053U discloses a raw material mixing device for cable pipe production, including a mixing cylinder, a cover plate fixed to the top of the mixing cylinder, an injection pipe fixed through the cover plate, the mixing cylinder and the injection pipe being interconnected, a number of partition hoppers being fixed from top to bottom inside the mixing cylinder, a conveying pipe being fixedly connected to the bottom of the partition hoppers, two reinforcing plates being fixed to the outer wall of the conveying pipe, and the height of a number of feeding and mixing components being adjustable by two hydraulic cylinders so that the feeding and mixing components cooperate with the conveying pipe;

[0004] Although the above solution can drive the second pulley to rotate via the transmission belt, thereby rotating the mixing component and mixing the raw materials, the cover plate only has one feeding pipe. This means that when adding materials, one type of material must be added into the mixing drum through the feeding pipe before adding another type of material. If there are many types of materials to be mixed, the mixing efficiency will be greatly reduced. At the same time, the multi-layer mixing component inside the mixing drum further increases the mixing time. Utility Model Content

[0005] To address the technical problem that adding multiple types of raw materials sequentially through the injection pipe significantly reduces mixing efficiency, and that the multi-layered stirring components inside the mixing cylinder further increase mixing time, this invention provides a raw material mixing device for the production of rigid polyvinyl chloride cable pipes.

[0006] This utility model is achieved using the following technical solution: a raw material mixing device for the production of rigid polyvinyl chloride cable pipes, comprising a first support frame and a second support frame, a rotatable mixing cylinder disposed between the first support frame and the second support frame, three feed inlets at the top of the mixing cylinder, three feed chambers matching the feed inlets disposed inside the mixing cylinder, each feed chamber having an inlet, a stirring chamber disposed below the feed chamber inside the mixing cylinder, a stirring rod disposed in the middle of the stirring chamber for mixing multiple raw materials, a discharge port fixedly connected to the bottom of the mixing cylinder, an electrically controlled bottom cover disposed at the bottom of the discharge port, and collection boxes disposed on both sides of the first support frame and the second support frame for collecting the mixture.

[0007] Through the above technical solution, various raw materials enter the feeding hopper from the three feed ports at the top of the mixing cylinder, and fall together from the feed ports into the mixing chamber at the bottom of the mixing cylinder. The various raw materials are mixed and stirred by the stirring rod in the mixing chamber, and finally flow out from the discharge port at the bottom of the mixing cylinder and are collected in the collection boxes on both sides of the first support frame and the second support frame.

[0008] As a further improvement to the above solution, a first servo motor is fixedly connected to the middle of the outer side of the top of the mixing cylinder, and the top of the stirring rod is rotatably connected to the middle of the inner side of the top of the mixing cylinder, and the top of the stirring rod is coaxially connected to the first servo motor.

[0009] Through the above technical solution, the first servo motor fixed to the middle of the outer side of the top of the mixing cylinder drives the stirring rod to rotate, thereby mixing and stirring various raw materials.

[0010] As a further improvement to the above solution, the bottom end of the stirring rod extends into the interior of the discharge port, and an auger blade is fixedly connected to the outer side of the stirring rod. A C-shaped rod is fixedly connected to the upper end of the outer side of the stirring rod, and multiple auxiliary rods are fixedly connected to the inner side of the C-shaped rod. The bottom end of the C-shaped rod slides on the inclined surface inside the mixing cylinder.

[0011] Through the above technical solution, the C-shaped rod on the outside of the stirring rod can better mix various raw materials in the mixing chamber. The auger blades fixed to the outside of the stirring rod can, on the one hand, drive the raw materials at the bottom of the mixing chamber to the middle or upper layer, realize multi-level mixing, and improve mixing efficiency and quality. On the other hand, the bottom end of the auger blades extending to the discharge port can also avoid excessive mixing of raw materials causing blockage.

[0012] As a further improvement to the above solution, a symmetrical connecting rod is fixedly connected to the outer side of the mixing cylinder, and the ends of the connecting rods are respectively rotatably connected to the inner sides of the first support frame and the second support frame. A second servo motor is fixedly connected to the outer side of the second support frame and coaxially connected to one of the ends of the connecting rods.

[0013] Through the above technical solution, the activation of the second servo motor can drive the mixing cylinder, which is fixed to the connecting rod, to rotate between the first support frame and the second support frame, thereby further improving the mixing of various raw materials.

[0014] As a further improvement to the above solution, a controller is fixedly connected to one of the outer sides of the first support frame parallel to the horizontal line, and the first servo motor, the second servo motor and the bottom cover are all electrically connected to the controller.

[0015] As a further improvement to the above solution, a flow divider block is fixedly connected between the first support frame and the second support frame, and the flow divider block is located directly below the mixing cylinder.

[0016] With the above technical solution, the diversion block is set in a V shape, so that the mixed raw materials flowing out of the outlet can flow into the collection box from the inclined surfaces on both sides of the diversion block. This reduces the force of the mixed raw materials falling by diverting the flow and prevents the mixed raw materials from jumping around when falling.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention utilizes the C-shaped rod on the outer side of the stirring rod to better mix various raw materials in the mixing chamber. The auger blades fixed to the outer side of the stirring rod can, on the one hand, move the raw materials at the bottom of the mixing chamber to the middle or upper layers, achieving multi-level mixing and improving mixing efficiency and quality. On the other hand, the extension of the bottom end of the auger blades to the discharge port can also prevent excessive mixing of raw materials from causing blockage. The activation of the second servo motor can drive the mixing cylinder fixed to the connecting rod to rotate between the first and second support frames, which can further improve the mixing of various raw materials.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Please combine Figures 1-5 This embodiment of a raw material mixing device for the production of rigid polyvinyl chloride (PVC) cable pipes includes a first support frame 1 and a second support frame 2. A rotatable mixing cylinder 3 is disposed between the first support frame 1 and the second support frame 2. The top of the mixing cylinder 3 has three feed inlets 4. The interior of the mixing cylinder 3 has three feed chambers that match the feed inlets 4. Each feed chamber has a feed inlet 5. A stirring chamber is disposed below the feed chambers inside the mixing cylinder 3. A stirring rod 6 for mixing multiple raw materials is disposed in the middle of the stirring chamber. An outlet 7 is fixed to the bottom of the mixing cylinder 3. An electrically controlled bottom cover 8 is disposed at the bottom of the outlet 7. Collection boxes 9 for collecting the mixture are provided on both sides of the frame 1 and the second support frame 2. By feeding multiple different raw materials into the feeding hopper from the three valve-controlled inlets 4 at the top of the mixing cylinder 3, the raw materials fall into the mixing hopper at the bottom of the mixing cylinder 3 from the inlets 5 of the different inlets, so that multiple different raw materials can be fed at the same time, which greatly shortens the feeding time. At this time, the multiple raw materials are mixed and stirred by the stirring rod 6 in the mixing hopper. Finally, the mixture flows out from the outlet 7 at the bottom of the mixing cylinder 3 and is collected in the collection boxes 9 on both sides of the first support frame 1 and the second support frame 2.

[0028] Combination Figure 2 and Figure 3A first servo motor 10 is fixedly connected to the middle of the outer side of the top of the mixing cylinder 3. The top of the stirring rod 6 is rotatably connected to the middle of the inner side of the top of the mixing cylinder 3, and the top of the stirring rod 6 is coaxially connected to the first servo motor 10. The bottom end of the stirring rod 6 extends into the interior of the discharge port 7, and an auger blade 11 is fixedly connected to the outer side of the stirring rod 6. A C-shaped rod 12 is fixedly connected to the upper outer end of the stirring rod 6, and multiple auxiliary rods 13 are fixedly connected to the inner side of the C-shaped rod 12. The bottom end of the C-shaped rod 12 slides on the inclined surface inside the mixing cylinder 3. The first servo motor 10, which is fixed to the middle of the outer side of the top, drives the stirring rod 6 in the middle of the mixing cylinder 3 to rotate. Due to the C-shaped rod 12 on the outer side of the stirring rod 6, it can better stir the various raw materials in the mixing chamber. The auger blades 11 fixed to the outer side of the stirring rod 6 can, on the one hand, drive the raw materials at the bottom of the mixing chamber to the middle or upper layer to achieve multi-level stirring, thereby improving the stirring efficiency and quality. On the other hand, the bottom end of the auger blades 11 extends to the discharge port 7, which can also prevent excessive mixing of raw materials from causing blockage.

[0029] Combination Figure 1 A symmetrical connecting rod 14 is fixedly attached to the outer side of the mixing cylinder 3. The ends of the connecting rod 14 are rotatably connected to the inner sides of the first support frame 1 and the second support frame 2, respectively. A second servo motor 15 is fixedly attached to the outer side of the second support frame 2 and coaxially connected to the end of one of the connecting rods 14. The second servo motor 15 fixedly attached to the outer side of the second support frame 2 drives the connecting rod 14 to rotate, so that the mixing cylinder 3 located between the first support frame 1 and the second support frame 2 can rotate 360 ​​degrees, so that the various raw materials inside the mixing cylinder 3 can be better mixed.

[0030] Combination Figure 1 and Figure 5 A controller is fixedly connected to the outer side of the first support frame 1, which is parallel to the horizontal line. The first servo motor 10, the second servo motor 15, and the bottom cover 8 are all electrically connected to the controller. A diverter block 16 is fixedly connected between the first support frame 1 and the second support frame 2. The diverter block 16 is located directly below the mixing cylinder 3. By electrically connecting the first servo motor 10, the second servo motor 15, and the bottom cover 8 to the controller, the operation of the equipment is made more intelligent. By setting the diverter block 16 in a V-shape, the mixed raw material flowing out of the outlet 7 can flow into the collection box 9 from the inclined surfaces on both sides of the diverter block 16. The force of the mixed raw material falling is reduced by diverting the flow, and the mixed raw material is prevented from jumping around when falling.

[0031] The implementation principle of the raw material mixing device for rigid polyvinyl chloride cable pipe production in this application embodiment is as follows:

[0032] Before starting, open the valves in the three feed ports 4 at the top of the mixing cylinder 3, and then feed various different raw materials into the feed hopper from the three feed ports 4. At this time, there are different raw materials in the three feed hoppers, and they fall into the mixing hopper below the mixing cylinder 3 from the feed ports 5 in the different feed hoppers. Then, the first servo motor 10 and the second servo motor 15 are turned on by the controller on the horizontal parallel outer side of the first support frame 1.

[0033] When the first servo motor 10 is turned on, it drives the stirring rod 6 in the middle of the mixing cylinder 3 to rotate. Due to the C-shaped rod 12 on the outside of the stirring rod 6, it can better stir the various raw materials in the mixing chamber. The auger blades 11 fixed to the outside of the stirring rod 6 can, on the one hand, drive the raw materials at the bottom of the mixing chamber to the middle or upper layer to achieve multi-level stirring, improve stirring efficiency and quality. On the other hand, the bottom end of the auger blades 11 extends to the discharge port 7, which can also prevent excessive mixing of raw materials from causing blockage.

[0034] When the second servo motor 15 is turned on, it drives the connecting rod 14 located inside the first support frame 1 and the second support frame 2 to rotate, so that the mixing cylinder 3 can rotate 360 ​​degrees, allowing the various raw materials inside the mixing cylinder 3 to be mixed better.

[0035] Finally, the bottom cover 8 of the discharge port 7 is opened by the controller, so that the mixed raw material falls from the bottom cover 8 and passes through the V-shaped diversion block 16, so that the mixed raw material can flow from the inclined surfaces on both sides of the diversion block 16 into the collection box 9.

[0036] At this time, the mixing rod 6 in the mixing chamber mixes and stirs the various raw materials, and finally flows out from the discharge port 7 at the bottom of the mixing cylinder 3, and is collected in the collection boxes 9 on both sides of the first support frame 1 and the second support frame 2.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
