Description

Technical Field

[0001] The utility model relates to the technical field of refined cotton processing, in particular to a refined cotton extrusion dehydration device. Background Art

[0002] Refined cotton is a high-purity cellulose product obtained by refining cotton linters through alkaline cooking, bleaching and other treatments. Its raw material is cotton linters. The production process of refined cotton includes a dehydration process, which is to separate the water from the refined cotton after cooking and bleaching by physical extrusion; the dehydration device is one of the important equipment in the production of refined cotton. When the refined cotton is dehydrated, the commonly used dehydration device is a roller-crushing dehydration device. When the equipment is performing roller-crushing dehydration, after the roller is separated from the refined cotton material, the retained water will be absorbed back by the material. Therefore, the dehydrated refined cotton material will still contain a lot of water, and a good dehydration effect cannot be achieved. At the same time, the refined cotton material after extrusion dehydration is in a relatively compact plate shape, which affects the subsequent drying efficiency. Therefore, the present application designs a refined cotton extrusion dehydration device that can improve the dehydration effect and ensure a fluffy state. Utility Model Content

[0043] A control cabinet 2 is fixedly mounted on the top of the base 1 , and a dehydration extrusion seat 3 located above the control cabinet 2 is fixedly mounted on the top of the base 1 .

[0044] In this embodiment, the base 1 is provided with a drainage and unloading assembly for isolating, filtering, draining and unloading the extruded raw materials.

[0045] It should be noted that the drainage and unloading assembly includes a hydraulic push rod 5 installed and fixed on the base 1, and a water accumulation and pressure-resistant seat 6 that slides in a sealed manner in the dehydration and extrusion seat 3 is installed and fixed on the push rod of the hydraulic push rod 5.

[0046] Among them, the water accumulation anti-pressure seat 6 is located inside the dehydration and extrusion seat 3 and has a plurality of drainage holes 7 distributed in a circular shape and at equal distances on one side.

[0047] When the push rod of the hydraulic push rod 5 is in the maximum extension state, the filter drainage net 8 is aligned with the upper surface of the dehydration extrusion seat 3, which is convenient for pushing the raw materials to the upper side after the extrusion and dehydration is completed, so as to facilitate unloading and material collection.

[0048] See also Figures 4 to 5 In this embodiment, the dehydration and extrusion seat 3 is provided with a driving component that drives the extrusion seat 4 to move downward, extrude and rotate.

[0049] It should be noted that the driving assembly includes a support frame 10 installed and fixed on the top of the dehydration extrusion seat 3 and a circular limiting groove 11 opened on the upper surface of the extrusion seat 4 and concentric with the extrusion seat 4. The diameter of the extrusion seat 4 is equal to the inner diameter of the dehydration extrusion seat 3.

[0050] Among them, a rotating frame 12 is provided for limiting the circular rotation in the circular limiting groove 11, and the rotating frame 12 and the circular limiting groove 11 are inseparable from each other. A driving motor 13 is fixedly installed on the rotating frame 12 to drive the extrusion seat 4 to rotate in circle. A connecting frame fixedly installed with the extrusion seat 4 is installed at the output shaft of the driving motor 13. The output shaft of the driving motor 13 is concentric with the extrusion seat 4. A hydraulic push rod 14 connected to the rotating frame 12 is fixedly assembled on the support frame 10.

[0051] In this embodiment, the extrusion seat 4 is provided with an exhaust component for conveying hot air flow into the extrusion seat 4 .

[0052] It should be noted that the exhaust assembly includes an upper exhaust component and a lower exhaust component.

[0053] Upper exhaust parts,

[0054] It includes a fan 15 and a heating seat 16 installed and fixed on the surface of the extrusion seat 4. The exhaust port of the fan 15 is connected to the heating seat 16. A heating wire is provided in the heating seat 16. An air pipe 17 is connected between the heating seat 16 and the extrusion seat 4.

[0055] The lower exhaust member,

[0056] It includes a fan 18 installed and fixed on the outside of the base 1, and a hose 19 is connected between the exhaust port of the fan 18 and the outside of the water-accumulating anti-pressure seat 6. The hose 19 is located at the opening on the inside of the water-accumulating anti-pressure seat 6 and is tilted downward to avoid squeezing water into it. The length of the hose 19 meets the distance required for the water-accumulating anti-pressure seat 6 to move up and down.

[0057] See also Figures 6 to 7 In this embodiment, the extrusion seat 4 is also provided with a stirring exhaust structure that cooperates with the driving component to drive the rotation to loosen and dehydrate the raw materials.

[0058] It should be noted that the toggle exhaust structure includes a hollow cylinder 20 installed and fixed inside the extrusion seat 4 and distributed at equal distances laterally based on the center of the circle. The hollow cylinder 20 is connected to the extrusion seat 4. A stainless steel spring 21 is installed and fixed in the hollow cylinder 20. The other end of the stainless steel spring 21 is installed and fixed with a movable tube 22 which is slidingly sealed and connected to the inner wall of the hollow cylinder 20 and passes through and extends to the bottom of the extrusion seat 4.

[0060] The working principle of the above embodiment is:

[0061] When in use, after putting the raw materials into the dehydration and extrusion seat 3, the hydraulic push rod 2 14 is started to push the rotating frame 12 and the extrusion seat 4 down to the dehydration and extrusion seat 3 to extrude the raw materials. The moving tube 22 is squeezed and moves and contracts synchronously in the hollow cylinder 20, and the stainless steel spring 21 is compressed synchronously. While cooperating with the filter and drainage net 8 to isolate the raw materials, the squeezed water is discharged into the water-retaining anti-pressure seat 6 through the drainage hole 7 and discharged through the water outlet hole 9;

[0062] After the extrusion is completed, the fan 2 18 is started to blow air into the water-retaining anti-pressure seat 6 through the hose 19 to dry the water on the upper surface of the inner cavity of the water-retaining anti-pressure seat 6 to prevent the raw material from absorbing the retained water;

[0063] In addition, after the extrusion dehydration is completed, the extrusion seat 4 is driven to move up and down by the operation of the push rod 2 14, and the drive motor 13, the fan 15 and the heating seat 16 are started synchronously, so that the drive motor 13 drives the extrusion seat 4 and the moving tube 22 to rotate, so that the moving tube 22 stirs and disperses the compacted raw materials, and as the extrusion seat 4 moves up and down, the stainless steel spring 21 stretches and contracts, and the moving tube 22 adapts to the pressure and expands and contracts. During the stirring process, the fan 15 discharges the airflow into the heating seat 16 to heat the airflow, so that the hot airflow is discharged into the extrusion seat 4 through the air pipe 17, and the mutual connection between the extrusion seat 4, the hollow cylinder 20, the moving tube 22 and the exhaust hole 23 is utilized, so that the hot airflow is discharged from the exhaust hole 23 into the raw material to cooperate with the stirring of the raw material, promotes the rapid fluffing of the raw material, and the hot airflow drives the residual moisture of the raw material to improve the dehydration effect.

[0064] The electrical components mentioned in this article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device that controls a computer, etc., and the existing public power connection technology is not described in detail in this article.
