Description

Technical Field

[0001] This application relates to the technical field of building material production, and in particular to a device for mixing waste polyester fiber and additives for building material production. Background Technology

[0002] Polyester fiber is a synthetic fiber made from organic diacids and diols through chemical polycondensation; it belongs to the category of polymer compounds. When using waste polyester fiber to make building materials, it needs to be mixed with additives.

[0003] A search revealed Chinese Patent Publication No. CN202121242015.0, which discloses a raw material mixing device for polyester fiber spinning production. The device includes a mixing tank, with a hydraulic rod vertically mounted on the top of the mixing tank. The top of the hydraulic rod is mounted on a suspension beam, and a groove is provided on one side of the mixing tank. A stirring frame is driven by a motor to stir and rotate inside the mixing tank. At the same time, the hydraulic rod drives the mixing tank to move up and down reciprocally. Thus, the stirring frame can mix and stir the raw materials in the upper, lower, and middle parts of the mixing tank, thereby improving the efficiency of raw material mixing.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: First, the mixing rack and mixing tank are an integrated structure, making it difficult to disassemble and clean the mixing rack after the device is used. The waste polyester fibers remaining on the mixing rack will seriously hinder subsequent work. Second, the discharge pipe lacks anti-clogging measures, and when the mixed polyester fibers are discharged, blockages can easily occur inside the discharge pipe, affecting the normal operation of the device.

[0014] 1. This utility model, by setting up a locking block, a locking slot, and a top frame, allows for the sequential pressing of multiple rubber pads when it is necessary to disassemble and clean components such as the stirring blade to avoid residue affecting subsequent mixing. This causes the rubber pads to move the locking block on the round rod, while the round rod also compresses the first spring. Then, the rubber pads are rotated, causing the locking block to rotate. After the locking block rotates to match the locking slot, it is pulled out of the locking slot on the mixing tank.

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses an apparatus for mixing waste polyester fiber and additives in building material production. For example... Figure 1As shown, the system includes a mixing tank 1, with a top frame 2 movably mounted on the top of the mixing tank 1. Two feed troughs 6 are provided on the top frame 2, and a motor 3 is fixedly connected to the top of the top frame 2. A rotating rod 4 is fixedly connected to the bottom of the motor 3, with its bottom end penetrating the top frame 2 and movably connected to it. Several stirring blades 5 are fixedly connected to the outer wall of the rotating rod 4. The motor 3 drives the multiple stirring blades 5 on the outside of the rotating rod 4 to stir the waste polyester fibers and additives inside the mixing tank 1, achieving rapid mixing. A connecting assembly is provided between the mixing tank 1 and the top frame 2, which secures the top frame 2 to the top of the mixing tank 1 and facilitates subsequent disassembly. A discharge pipe 15 is inserted and installed at the bottom of the mixing tank 1. An anti-clogging component is provided inside the discharge pipe 15 to prevent clogging and avoid the accumulation of mixed materials inside the discharge pipe 15.

[0024] Please see Figure 3 and Figure 5 The connecting assembly includes several fixing brackets 9, which are respectively fixedly installed on the top of the top frame 2. A round rod 11 is movably installed through the top of each fixing bracket 9. Several slots 8 are provided on the top of both the top frame 2 and the top of the mixing tank 1. The upper and lower slots 8 are interconnected. The bottom end of the round rod 11 passes through two adjacent slots 8 and is fixedly connected to a locking block 10. The locking block 10 fits against the outer wall of the mixing tank 1. A round block 13 is fixedly installed on the outer side of the round rod 11, and a first spring 12 is also installed on the outer side of the round rod 11. The two ends of the spring 12 are fixedly connected to the bottom of the round block 13 and the top of the top frame 2, respectively. By pressing the multiple round rods 11, the corresponding locking blocks 10 are moved. Then, the round rods 11 drive the locking blocks 10 to rotate. When the locking blocks 10 rotate to match the locking slots 8, the multiple locking blocks 10 can be pulled out of the locking slots 8 on the mixing tank 1, realizing the separation of the mixing tank 1 from the top frame 2. This further realizes the separation of the No. 1 motor 3, rotating rod 4 and stirring blade 5 on the top frame 2 from the mixing tank 1, which facilitates subsequent cleaning and avoids material residue affecting subsequent stirring.

[0025] Please see Figure 5 Each of the round rods 11 has a rubber pad 14 fixedly connected to its top end. The rubber pads 14 are all hemispherical. The rubber pads 14 at the top of the round rods 11 provide a certain degree of protection, making it more comfortable to apply force to the round rods 11.

[0026] Please see Figure 2 and Figure 4The anti-blocking component includes a movable column 16, which is located inside the discharge pipe 15 and extends to the bottom of the discharge pipe 15. Two fixed plates 26 are fixedly connected to the outer wall of the movable column 16. Cams 25 are attached to the top of the two fixed plates 26. A rotating shaft 24 is fixedly installed through the cams 25. A second motor 23 is fixedly connected to one end of the rotating shaft 24. By driving the second motor 23, the rotating shaft 24 is driven to rotate. The rotating shaft 24 drives the cams 25 to push the fixed plates 26. The fixed plates 26 drive the movable column 16 to move up and down repeatedly inside the discharge pipe 15, thereby achieving anti-blocking measures inside the discharge pipe 15. Movable components are provided on the outside of the movable column 16.

[0027] Please see Figure 4 The movable component includes two side plates 17, both of which are fixedly connected to the outer wall of the movable column 16. Each side plate 17 has a fixing plate 19 at its top, which is fixedly connected to the outer wall of the discharge pipe 15. Each fixing plate 19 also has a stop block 21 at its top, and a vertical rod 18 is fixedly connected to the bottom of each stop block 21. The bottom end of the vertical rod 18 passes through the fixing plate 19 and is fixedly connected to the top of the side plate 17. The vertical rod 18 is movably connected to the fixing plate 19, and a second spring 20 is movably mounted on the outside of the vertical rod 18. The two ends of the second spring 20 are fixedly connected to the bottom of the fixing plate 19 and the top of the side plate 17, respectively. When the movable column 16 is pushed, it causes the two outer side plates 17 to move synchronously. At this time, the two side plates 17 stretch the corresponding second spring 20. When the cam 25 stops pushing, the movable column 16 will reset under the elastic force of the second spring 20, achieving the purpose of the movable column 16 repeatedly moving up and down inside the discharge pipe 15, further realizing anti-blocking measures.

[0028] Please see Figure 4 Both No. 2 motors 23 are fixedly connected to the outer walls of the two motors 23. The connecting frame 22 is fixedly connected to the outer wall of the discharge pipe 15. The connecting frame 22 is used to fix the No. 2 motor 23 to the discharge pipe 15, so as to ensure the stability of the No. 2 motor 23 during subsequent operation.

[0029] Please see Figure 2 The top of the top frame 2 is equipped with two sealing plugs 7. The two sealing plugs 7 are respectively inserted into the inner cavity of the corresponding feed trough 6. The sealing plugs 7 are used to seal the inside of the feed trough 6 to prevent external debris from entering the mixing tank 1 through the feed trough 6 during the mixing process and affecting the quality of the mixed product.

[0030] The implementation principle of the waste polyester fiber and additive mixing device for building material production in this application embodiment is as follows: First, remove the two sealing plugs 7 and inject the additive and waste polyester fiber into the two feeding troughs 6 according to the ratio. After all the filling is completed, reinsert the sealing plugs 7 into the corresponding feeding troughs 6 and drive the No. 1 motor 3, so that the No. 1 motor 3 drives the rotating rod 4 to rotate. The rotating rod 4 drives multiple stirring blades 5 on the outside to rotate, and the multiple stirring blades 5 are used to achieve rapid mixing of waste polyester fiber and additive.

[0031] After mixing, when discharge is required, two No. 2 motors 23 can be driven synchronously, so that the two No. 2 motors 23 drive the rotating shaft 24 to rotate, the rotating shaft 24 drives the cam 25 to rotate, the cam 25 pushes the fixed plate 26 to move, the fixed plate 26 drives the movable column 16 to move, the movable column 16 drives the two side plates 17 on its outer side to move synchronously, the side plates 17 drive the top vertical rod 18 to move, and at the same time compress the corresponding No. 2 spring 20. When the cam 25 stops pushing, the movable column 16 will be reset under the action of the two No. 2 springs 20 on the outer side. The continuous rotation of the cam 25 realizes that the movable column 16 moves up and down repeatedly inside the discharge pipe 15 to achieve the anti-blocking function. The subsequently mixed material is discharged through the discharge pipe 15.

[0032] When it is necessary to disassemble and clean components such as the stirring blade 5 to avoid residue affecting subsequent mixing, multiple rubber pads 14 can be pressed in sequence, causing the rubber pads 14 to move the locking blocks 10 on the round rod 11. At the same time, the round rod 11 also causes the round block 13 to compress the first spring 12. Then, rotate the rubber pads 14, causing the rubber pads 14 to rotate the locking blocks 10. After the locking blocks 10 rotate to match the locking slot 8, pull the locking blocks 10 out of the locking slot 8 on the mixing tank 1. After all the locking blocks 10 are completely removed from the mixing tank 1, the top frame 2, along with the first motor 3, stirring blade 5, and other components, can be removed from the inside of the mixing tank 1 for cleaning. The above operation can be repeated for subsequent installation.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
