DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-2 In this embodiment, a diacetate fiber desizing device includes a desizing tank 1. It should be noted that support legs are fixed to the four sides of the bottom of the desizing tank 1. The support legs can elevate the entire device. A force-balancing block is fixed to the bottom of the support legs. The force-balancing block is narrow at the top and wide at the bottom. Its bottom area increases the contact area between the support legs and the ground, thereby increasing the stability of the device. A sealed door 2 is hingedly connected to the front of the desizing tank 1. It should be noted that the front of the sealed door 2 is inlaid with an observation glass, which allows the operator to observe the interior of the desizing tank 1 from the outside. A handle is fixed to the front of the sealed door 2, providing a grip point. The handle has a U-shaped cross-section. A non-slip rubber sleeve is fixed to the outer surface of the handle. The non-slip rubber sleeve increases friction on the outer surface and increases the pressure area of the hand by deforming, making the grip more secure and more comfortable. A drain pipe 3 is fixed to the bottom of the inner cavity of the desizing tank 1 and extends to the outside. The drain pipe 3 has an L-shaped cross-section. The L-shaped drain pipe 3 can discharge sewage from the interior of the desizing tank 1 from below.

[0027] It should be noted that the inner surface of the desizing tank 1 is fixed with a drainage slope fixed to its bottom. The drainage slope can guide the sewage from the surrounding areas to the center. The bottom of the inner cavity of the desizing tank 1 is provided with a ring-shaped drainage groove. The drainage groove is ring-shaped and can concentrate the sewage that converges centripetally from the surrounding areas, and guide the sewage to the drain pipe 3 through its structure. The drain pipe 3 is located inside the drainage groove, which can enhance the sewage collection capacity.

[0028] Furthermore, a feeding assembly is fixed on the top of the desizing tank 1 and passes through the interior thereof. It should be noted that the feeding assembly includes a feeding pipe 4 fixed on the top of the desizing tank 1 and passing through the interior thereof, and a feeding pipe 4 is fixed on the top of the desizing tank 1 and passes through the interior thereof. The feeding pipe 4 can introduce the raw materials into the interior of the desizing tank 1, and a feeding hopper 5 is fixed on the top of the feeding pipe 4. The feeding hopper 5 is wide at the top and narrow at the bottom, which can facilitate the gathering and feeding of materials. A support block 6 is fixed on the top of the desizing tank 1, and an electric hydraulic rod 7 is fixed on the front of the support block 6, and the telescopic end of the electric hydraulic rod 7 is In front, the telescopic end of the electric hydraulic rod 7 is fixed with a desizing mechanism 8 that penetrates into the interior of the desizing tank 1 and is slidably connected thereto. The raw materials put in will fall into the desizing mechanism 8. The desizing mechanism 8 is used to screen and wash the raw materials. The back of the desizing tank 1 is fixed with an injection pipe 9 that penetrates into the interior. The injection pipe 9 is used to inject cleaning liquid. Cleaning liquid can be continuously injected into the interior through the injection pipe 9 to facilitate desizing. It should be noted that the cross-section of the injection pipe 9 is L-shaped, and the water outlet end of the injection pipe 9 is downward. The cleaning liquid injected by the injection pipe 9 can fall into the interior of the desizing mechanism 8.

[0029] During operation, the feeding pipe 4 introduces the raw material into the desizing tank 1 and drops it onto the desizing mechanism 8, and the injection pipe 9 introduces the cleaning liquid into the desizing mechanism 8, thereby performing centrifugal vibration desizing during the operation of the desizing mechanism 8.

[0030] See also Figure 3-5 In order to screen the raw materials and separate the solid and liquid, the desizing mechanism 8 in this embodiment includes a sliding rod 801 fixed to the telescopic end of the electric hydraulic rod 7 and extending into the interior of the desizing tank 1. It should be noted that a sliding groove is provided on the top of the desizing tank 1, and the sliding rod 801 is located inside the sliding groove. The sliding groove can limit the sliding range of the sliding rod 801. A waterproof plate covering the sliding groove is fixed on the front of the sliding rod 801. The waterproof plate can cover the sliding groove when the device is running to prevent the liquid inside from spilling out.

[0031] In addition, a mechanism box 802 is fixed to the bottom of the sliding rod 801, and a servo motor 803 is fixed to the top of the inner cavity of the mechanism box 802, and the output shaft of the servo motor 803 is downward. When the servo motor 803 runs, its output shaft drives the rotating shaft 804 to gradually speed up. The raw material barrel 8062 with raw materials inside starts to rotate under the drive of the continuously rotating rotating shaft 804. As the rotation force gradually increases, the speed gradually increases. The output shaft of the servo motor 803 is fixed to a shaft that runs through the bottom of the mechanism box 802. The rotating shaft 804 has a sliding block 805 fixed at the bottom of the rotating shaft 804, which is slidably connected to the bottom of the inner cavity of the desizing tank 1. The cross-section of the sliding block 805 is T-shaped. The outer surface of the rotating shaft 804 is movably connected to the desizing component 806. The water outlet end of the injection pipe 9 is located above the desizing component 806. The raw material is introduced into the desizing tank 1 from the top of the feeding hopper 5 through the feeding pipe 4 and falls into the interior of the raw material barrel 8062. The injection pipe 9 introduces the cleaning liquid into the raw material barrel 8062 to clean and desizing the raw material.

[0032] It should be noted that the deslurrying assembly 806 includes a movable tube 8061 movably connected to the outer surface of the rotating shaft 804, and a raw material barrel 8062 is fixed to the outer surface of the movable tube 8061. The outer surface of the raw material barrel 8062 is provided with a plurality of filter holes 8063. The centrifugal force generated by the rotation causes the mixed slurry flushed out from the inside to be thrown out from the multiple filter holes 8063, and the sewage is guided into the drainage trough by the drainage slope and discharged through the drain pipe 3.

[0033] It should be noted that a vibration groove is provided on the inner surface of the rotating shaft 804, and the cross-section of the vibration groove is wavy. Sliding steps 8064 located inside the vibration groove are fixed on the left and right sides of the inner surface of the movable tube 8061. The servo motor 803 stops running and the output shaft is braked and no longer rotates. At this time, the raw material barrel 8062 will continue to rotate under the action of centrifugal inertia, and the sliding step 8064 inside it will vibrate at high speed inside the wavy vibration groove, so that the remaining moisture will be separated from the de-sized fibers during the vibrating rotation.

[0034] In general, the servo motor 803 drives the rotating shaft 804 to rotate, and the raw material barrel 8062 starts to rotate at an accelerated speed under the drive of the rotating shaft 804, and the mixed slurry flushed out from the inside is thrown out from the multiple filter holes 8063 through centrifugal force.

[0035] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0036] The working principle of the above embodiment is:

[0037] During use, the raw materials are introduced into the desizing tank 1 through the feeding pipe 4 from the top of the feeding hopper 5 and fall into the interior of the raw material barrel 8062. The injection pipe 9 introduces the cleaning liquid into the raw material barrel 8062 to clean and desizing the raw materials. The servo motor 803 runs, and its output shaft drives the rotating shaft 804 to gradually speed up. The raw material barrel 8062 with raw materials inside starts to rotate under the drive of the continuously rotating rotating shaft 804. As the rotational force gradually increases, the speed gradually increases. The centrifugal force generated by the rotation causes the mixed slurry flushed out from the interior to be thrown out from the multiple filter holes 8063. The sewage is guided into the drainage trough by the drainage slope and discharged through the drain pipe. 3. After the flushing and desizing is completed, the servo motor 803 stops running and the output shaft is braked to stop rotating. At this time, the raw material barrel 8062 will continue to rotate under the action of centrifugal inertia, and the sliding sill 8064 inside it will vibrate at high speed inside the wave-shaped vibration groove, so that the remaining water will be separated from the desizing fibers during the vibration and rotation, and the water content of the finished product will be controlled. After the mechanism stops completely, the sealing door 2 can be opened and the electric hydraulic rod 7 can be started. The electric hydraulic rod 7 pushes the sliding rod 801, so that the internal rotating shaft 804 and the raw material barrel 8062 move forward under the action of force transmission and extend out of the sealing door 2, so that the finished product can be collected.
