Abstract
Description
Technical Field

[0002] In the PVC (polyvinyl chloride) production process, the mixing unit is a key pretreatment device used to uniformly mix PVC resin powder with various additives (such as stabilizers, plasticizers, fillers, lubricants, pigments, etc.).
[0003] Existing mixing mechanisms typically use a single shaft to drive the stirring rod, causing the internal mixture to flow in one direction. Some raw materials are located at the inner wall edge or at the discharge pipe, making it difficult for them to participate in the mixing process, resulting in poor mixing efficiency. At the same time, the mixing process is heated from the outside, causing the raw materials inside the chamber to be hot on the outside and cold on the inside. It is difficult for the external material and the internal material to be interchanged, resulting in uneven heating. Furthermore, existing mixing mechanisms usually pour raw materials into the feed pipe in large quantities, which can easily cause blockage of the feed pipe and affect the feeding efficiency.

[0026] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0027] Example 1
[0028] Please see Figure 1-5In this embodiment, a PVC production mixing mechanism is provided, including: a box 1, a rotary motor 2 installed on the top of the box 1, a feed pipe 6 connected to the top of the box 1, and an equipment box 5 fixedly connected to one side of the box 1; a heating assembly disposed between the equipment box 5 and the box 1, the heating assembly including: a first heater 501, a second heater 502, a first electric heating tube 401 and a second electric heating tube 301; and an anti-blocking assembly disposed inside the feed pipe 6, the anti-blocking assembly including: an equipment cavity 602, a drive motor 603, a cam 604 and an extrusion plate 609.
[0029] The heating components ensure uniform mixing of raw materials inside the chamber 1 and uniform heating of the raw materials, preventing uneven heating. The anti-blocking components prevent material from clogging the feed chute 601, ensuring efficient material feeding.
[0030] Example 2
[0031] Based on Embodiment 1, a flow pipe 3 is connected inside the box 1, and a discharge pipe 101 is connected to the bottom of the box 1. The discharge pipe 101 is connected to the flow pipe 3. Two symmetrically arranged flow ports 302 are opened on the outside of the flow pipe 3. A second electric heating tube 301 is provided inside the flow pipe 3. A heat-conducting plate 4 is installed inside the box 1. A first electric heating tube 401 is connected inside the heat-conducting plate 4. A first heater 501 and a second heater 502 are installed inside the equipment box 5. The first electric heating tube 401 is connected to the first heater 501, and the second electric heating tube 301 is connected to the second heater 502. A rotating rod 201 is driven and connected to the bottom of the rotating motor 2. An auger 203 is connected to the bottom end of the rotating rod 201. The bottom end of the auger 203 passes through the flow pipe 3 and extends into the discharge pipe 101. A uniformly distributed stirring rod 202 is connected to the outside of the rotating rod 201.
[0032] In the PVC production process, PVC resin powder is uniformly mixed with various additives. At this time, the raw materials and additives can be added into the box 1 through the feed pipe 6. Then, the rotating rod 201 is rotated by the rotating motor 2, which in turn drives the stirring rod 202 to rotate, mixing the raw materials and additives inside the box 1. At the same time, the first heating tube 401 and the second heating tube 301 are energized by the first heater 501 and the second heater 502, respectively. The first heating tube 401 generates heat and transfers it into the box 1 through the heat conduction plate 4, while the heat generated by the second heating tube 301 directly heats the flow tube 3. With the rotation of the stirring rod 202, the raw materials and additives are heated and mixed.
[0033] Furthermore, during the mixing process, the mixture of raw materials and additives can enter the flow tube 3 through the flow port 302. As the rotating rod 201 rotates, it also drives the auger 203 to rotate, so that the auger 203 can lift the mixture at the discharge pipe 101 and the flow port 302 upward. When the mixture passes through the inside of the flow tube 3, it can be heated evenly, while ensuring that all additives and raw materials participate in the mixing. As the auger 203 continues to rotate, the mixture inside the box 1 forms a flow pattern from the outside towards the flow port 302 and is discharged from the top of the flow tube 3, which improves the mixing efficiency.
[0034] After mixing is complete, the solenoid valve at the discharge pipe 101 can be opened, and then the rotary motor 2 can be reversed to make the auger 203 convey downwards, discharging the mixture inside the box 1 and the flow pipe 3 to the outside, while avoiding blockage of the discharge pipe 101.
[0035] Example 3
[0036] Based on Embodiment 1, a feeding trough 601 communicating with the interior of the housing 1 is provided at the top of the feeding pipe 6. An equipment cavity 602 is provided inside the feeding pipe 6. A drive motor 603 is installed inside the equipment cavity 602. A movable groove is provided inside the feeding pipe 6, and the movable groove communicates with the equipment cavity 602 and the feeding trough 601. An extrusion plate 609 is movably connected inside the movable groove. A fixed plate 605 is connected inside the movable groove. A through hole is provided on the fixed plate 605, and a moving rod 608 passes through the through hole. One end of the moving rod 608 is connected to the extrusion plate 609, and the other end of the moving rod 608 is connected to a moving plate 606. A cam 604 is driven and connected to the surface of the drive motor 603, and one side of the moving plate 606 is in contact with the cam 604. Two moving springs 607 are connected between the moving rod, moving plate 606, and fixed plate 605, and the moving springs 607 are symmetrically arranged about the moving rod 608.
[0037] To prevent excessive pouring of raw materials and additives from clogging the feed pipe 6 and affecting the feeding process, the drive motor 603 can rotate the cam 604, causing the protruding part of the cam 604 to move towards the moving plate 606 and press the moving plate 606. This causes the moving plate 606 to move the pressing plate 609 towards the feed trough 601 via the moving rod 608. At the same time, the moving spring 607 is compressed and accumulates elasticity. When the protruding part of the cam 604 separates from the moving plate 606, the moving plate 606, under the elasticity of the moving spring 607, causes the pressing plate 609 to rebound, realizing the reciprocating movement of the pressing plate 609. This prevents raw materials or additives from clogging the feed trough 601.
