Description

Technical Field

[0001] This utility model relates to the field of polymer production equipment technology, and in particular to a mixing tank for producing high-transparency polypropylene granules. Background Technology

[0002] High-transparency polypropylene granules are a high-performance plastic material with wide applications in many fields due to their unique physical and chemical properties. High-transparency polypropylene granules are an important modified variety of polypropylene, which has higher light transmittance and transparency through specific production processes and additives.

[0003] Chinese patent discloses a mixing tank for producing highly transparent modified polypropylene granules (authorization announcement number CN217646281U). This patented technology uses a rotating mechanism to drive a motor to rotate a fixed frame, and the rotation of the fixed frame enables the mixing tank to rotate. This allows the raw materials inside the mixing tank to tumble up and down, facilitating mixing and greatly improving the mixing effect.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: Existing mixing tanks for the production of high-transparency polypropylene granules usually discharge the mixed material by direct discharge, which makes it impossible to control the discharge amount of the mixed material. When the discharge amount is too large, the excess part is often discarded or needs to be reprocessed, which not only increases production costs, but also imposes an unnecessary burden on the environment. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing mixing tanks used in the production of high-transparency polypropylene granules usually discharge the mixed material directly, and it is impossible to accurately control the discharge amount. This results in the excess material having to be discarded or reprocessed when there is too much material discharged, which increases costs and burdens the environment. Therefore, we propose a mixing tank for the production of high-transparency polypropylene granules.

[0006] To achieve the above objectives, this application adopts the following technical solution: a mixing tank for producing high-transparency polypropylene granules, comprising a mixing tank body, a discharge pipe installed at the bottom of the mixing tank body, a movable groove opened at one end of the discharge pipe, a hollow block fixedly connected to one end of the discharge pipe, a baffle slidably connected inside the movable groove, a pull block fixedly connected to one end of the baffle, slots opened on both sides of the inner cavity of the hollow block, and a fixing mechanism for fixing the position of the baffle installed on the top of the pull block.

[0007] Preferably, the fixing mechanism includes a cavity block installed on the top of the pull block, an installation plate is fixedly connected inside the cavity block, an adjusting rod is slidably connected inside the installation plate, an arc-shaped pushing block is fixedly connected to the bottom of the adjusting rod, arc-shaped force-bearing blocks abut against both sides of the arc-shaped pushing block, a locking block is fixedly connected to one side of the arc-shaped force-bearing block, and through slots are provided on both sides of the cavity block.

[0008] Preferably, a return spring is fixedly connected to one side of the arc-shaped force-bearing block, and one side of the return spring is fixedly connected to the interior of the cavity block.

[0009] Preferably, the bottom of the cavity block is provided with a sliding groove, and the bottom of the arc-shaped force-bearing block is fixedly connected with a slider.

[0010] Preferably, the outer surface of the card block is slidably connected to the inside of the card slot, and the outer shape of the card block matches the inner shape of the card slot.

[0011] Preferably, limit grooves are provided on both sides of the cavity block, and limit blocks are fixedly connected to both sides of the arc-shaped push block.

[0012] Preferably, the surface of the baffle is slidably connected to the interior of the moving groove, and a wear-resistant layer is provided on the top of the baffle.

[0013] Preferably, guide grooves are provided on both sides of the inner cavity of the hollow block, and guide blocks are fixedly connected to both sides of the hollow block.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] In this invention, the operator pulls a lever to make the baffle slide inside the moving groove. When the baffle reaches the predetermined position, the position of the arc-shaped push block is adjusted by moving the adjusting rod. The arc-shaped push block drives the arc-shaped force blocks on both sides to insert the locking blocks into the corresponding slots, thus fixing the position of the baffle. This allows the operator to control the flow rate of the mixing tank body outlet, which helps to reduce material waste caused by excessive discharge. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a mixing tank for producing high-transparency polypropylene granules, including a mixing tank body 1, a discharge pipe 2 installed at the bottom of the mixing tank body 1, a moving groove 3 opened at one end of the discharge pipe 2, a hollow block 6 fixedly connected to one end of the discharge pipe 2, a baffle 4 slidably connected inside the moving groove 3, a pull block 5 fixedly connected to one end of the baffle 4, slots 8 opened on both sides of the inner cavity of the hollow block 6, a fixing mechanism for fixing the position of the baffle 4 installed on the top of the pull block 5, the fixing mechanism including a cavity block 7 installed on the top of the pull block 5, an mounting plate 9 fixedly connected inside the cavity block 7, an adjusting rod 10 slidably connected inside the mounting plate 9, and a fixed connection at the bottom of the adjusting rod 10. An arc-shaped pushing block 11 has arc-shaped force-bearing blocks 12 on both sides. A locking block 13 is fixedly connected to one side of the arc-shaped force-bearing block 12. Through slots 14 are opened on both sides of the cavity block 7. The operator pulls the pulling block 5, which causes the baffle 4 to slide inside the moving slot 3. When the baffle 4 reaches the predetermined position, the position of the arc-shaped pushing block 11 is adjusted by moving the adjusting rod 10. The arc-shaped pushing block 11 drives the arc-shaped force-bearing blocks 12 on both sides to insert the locking block 13 into the corresponding locking slot 8, thus fixing the position of the baffle 4. This allows the operator to control the flow rate of the mixing tank body 1 outlet, which helps to reduce material waste caused by excessive discharge.

[0024] Reference Figure 5As shown in this embodiment: a return spring 17 is fixedly connected to one side of the arc-shaped force block 12, and one side of the return spring 17 is fixedly connected to the inside of the cavity block 7. The return spring 17 is set so that the arc-shaped force block 12 can be quickly pulled to pop the card block 13 out of the card slot 8, making it more convenient for the operator to use.

[0025] Reference Figure 4 and Figure 5 As shown in this embodiment: a groove 16 is provided at the bottom of the cavity block 7, and a slider 15 is fixedly connected to the bottom of the arc-shaped force block 12. The cooperation between the slider 15 and the groove 16 allows the arc-shaped force block 12 to move or adjust relative to the cavity block 7 to a certain extent, so that the arc-shaped force block 12 is more stable during the movement and will not shake.

[0026] Reference Figure 2 and Figure 5 As shown in this embodiment: the outer surface of the card block 13 is slidably connected to the inside of the card groove 8, the outer shape of the card block 13 matches the inner shape of the card groove 8, and the tight fit between the card block 13 and the card groove 8 effectively prevents the card block 13 from loosening or falling off due to material pressure or vibration during the stirring process, thereby ensuring the stability of the baffle 4 during use.

[0027] Reference Figure 4 and Figure 5 As shown in this embodiment: limit grooves 18 are provided on both sides of the cavity block 7, and limit blocks 19 are fixedly connected to both sides of the arc-shaped push block 11. The mutual cooperation between the limit blocks 19 and the limit grooves 18 enables the adjusting rod 10 to drive the arc-shaped push block 11 to move downwards and better align with the top of the arc-shaped force block 12, thereby improving the adjustment accuracy.

[0028] Reference Figure 3 As shown in this embodiment: the surface of the baffle 4 is slidably connected to the interior of the moving groove 3, and a wear-resistant layer is provided on the top of the baffle 4. The material of the wear-resistant layer is a composite material with high wear resistance and corrosion resistance, which ensures that the surface of the baffle 4 will not be excessively worn due to friction with the material during long-term stirring, and also reduces the adhesion of the material during the stirring process.

[0029] Reference Figure 2 and Figure 3 As shown in this embodiment: guide grooves 20 are provided on both sides of the inner cavity of the hollow block 6, and guide blocks 21 are fixedly connected to both sides of the hollow block 7. The guide grooves 20 are usually designed to match the shape of the guide blocks 21 so that when the hollow block 7 is assembled with the hollow block 6, the guide blocks 21 can smoothly slide into the guide grooves 20, which not only ensures the precise alignment between the components, but also provides a stable connection.

[0030] Working principle: By pulling the pull block 5, the operator causes the baffle 4 to slide inside the moving groove 3. When the baffle 4 reaches the predetermined position, the position of the arc-shaped push block 11 is adjusted by moving the adjusting rod 10. The arc-shaped push block 11 drives the arc-shaped force blocks 12 on both sides to insert the locking block 13 into the corresponding locking slot 8, thus fixing the position of the baffle 4. This allows the operator to control the flow rate of the mixing tank body 1, helping to reduce material waste caused by excessive discharge. The reset spring 17 is designed to quickly pull the arc-shaped force block 12 to pop the locking block 13 out of the locking slot 8, making it easier for the operator to use. The cooperation between the slider 15 and the slide groove 16 allows the arc-shaped force block 12 to move or adjust relative to the cavity block 7 to a certain extent, making the arc-shaped force block 12 more stable during movement and preventing wobbling. The tight fit between the locking block 13 and the locking groove 8 effectively prevents the locking block 13 from loosening or falling off due to material pressure or vibration during the stirring process, thus ensuring the stability of the baffle 4 during use. The mutual cooperation between the limiting block 19 and the limiting groove 18 allows the adjusting rod 10 to better align with the top of the arc-shaped force block 12 when it drives the arc-shaped push block 11 downward, improving the adjustment accuracy. The wear-resistant layer is made of a composite material with high wear resistance and corrosion resistance, ensuring that the surface of the baffle 4 will not be excessively worn due to friction with the material during long-term stirring. In addition, it can reduce the adhesion of the material during the stirring process. The guide groove 20 is usually designed to match the shape of the guide block 21 so that when the cavity block 7 and the hollow block 6 are assembled, the guide block 21 can smoothly slide into the guide groove 20, which not only ensures the precise alignment between the components, but also provides a stable connection.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
