[0004] Although this equipment can perform dehydration, it is not easy to adapt to bottle flakes of different sizes and is prone to clogging. Therefore, we propose a bottle flake dehydrator. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-4 As shown, in this embodiment, a bottle flake dehydrator includes an outer cylinder 1, an inner cylinder 2 is provided inside the outer cylinder 1, and a plurality of drainage holes 3 are provided through the outer side of the inner cylinder 2; a dehydration component 4 is provided inside the inner cylinder 2, which can adjust the distance between itself and the inner wall of the inner cylinder 2 to adjust the size of its dehydration space.

[0029] The dehydration assembly 4 includes a motor 41, a hydraulic cylinder 42, a rotating rod 43, and a support rod 44. The motor 41 is fixedly connected to the top of the outer cylinder 1, and a chain 411 is fixedly connected to the drive end of the motor 41. A box 7 is fixedly connected to the top of the outer cylinder 1. The box 7 is fitted over the motor 41 and the chain 411 to protect them. ， A hydraulic cylinder 42 is installed inside the inner cylinder 2. A driven wheel 421 is fixedly sleeved on the outside of the hydraulic cylinder 42. One end of a chain 411 is sleeved on the outside of the driven wheel 421. A sleeve 422 is fixedly connected to the bottom end of the hydraulic cylinder 42. Multiple sliding grooves 423 are opened through the outer side of the sleeve 422. A collar 424 is slidably sleeved on the outside of the sleeve 422. The inner side of the collar 424 extends into the sliding grooves 423 and is fixedly connected to the drive end of the hydraulic cylinder 42. Multiple rotating rods 43 are rotatably connected to the outside of the collar 424. An arc-shaped plate 431 is rotatably connected to the outer end of the multiple rotating rods 43. A support rod 44 is fixedly connected to the bottom end of the sleeve 422. Multiple support rods 441 are rotatably connected, and the outer ends of the multiple support rods 441 are rotatably connected to the middle parts of multiple rotating rods 43 respectively. The number of hydraulic cylinders 42, sleeves 422, slides 423, collars 424, rotating rods 43, arc plates 431 and support rods 441 are set in two groups, which are arranged vertically opposite each other and are fixedly connected to each other by support rods 44. The lower hydraulic cylinders 42 are rotatably connected to the bottom of the outer cylinder 1 by bearings. It should be noted that the chain 411 and the driven wheel 421 are well-fitted, and the cooperation between the chain 411, the driven wheel 421 and the drive end of the motor 41 is smooth, with moderate tension, and stable operation.

[0030] like Figure 4 As shown, in this embodiment, multiple rotating rods 43, arc plates 431 and support rods 441 are arranged around the central axis of support rod 44. Multiple arc plates 431 can be combined into a circle. Folding plates 45 are fixedly connected to multiple arc plates 431. The folding plates 45 are foldable and can be moved in and out of the multiple arc plates 431 in conjunction with each other, which can prevent materials from entering the dewatering component 4 and making it difficult to clean.

[0031] like Figure 2 As shown, the bottom of the outer cylinder 1 is provided with a discharge port 5, which is connected to the inner cylinder 2. The outer cylinder 1 is provided with a water outlet 6, which is used for discharging material and the water outlet 6 is used for draining water.

[0032] like Figure 1 As shown, the outer cylinder 1 is further slidably connected to the first door 8, and the inner cylinder 2 is slidably connected to the second door 9. The first door 8 and the second door 9 can be opened and closed to prevent materials from falling out during operation.

[0033] In practice, the upper and lower hydraulic cylinders 42 are activated, driving the upper and lower collars 424 to move relative to each other towards the middle of the support rod 44. This causes the upper and lower sets of rotating rods 43 to rotate under the fulcrum of the support rod 441, which in turn causes multiple arc plates 431 to expand and contract inwards. That is, the distance between the arc plates and the inner wall of the inner cylinder 2 can be adjusted to adjust the size of the dehydration space. By setting the dehydration component 4, which can adjust the size of the dehydration space, the adaptability is enhanced: by adjusting the dehydration space, it can accommodate bottle flakes of different sizes and shapes, ensuring that all bottle flakes can fully contact the dehydration elements inside the dehydration component 4, thereby improving the dehydration efficiency. In addition, multiple arc plates 431 can be retracted to facilitate material falling and prevent blockage.

[0034] Working principle: First, open the first door 8 and the second door 9, put the bottle flakes into the inner cylinder 2, and then start the motor 41. The motor 41 drives the chain 411 to rotate, which in turn drives the driven wheel 421 to rotate, thus driving the entire dehydration assembly 4 to rotate. Multiple lifting guide plates are set on the outside of multiple arc plates 431. Through centrifugal rotation, the bottle flakes rise, and the liquid will be discharged through the drain hole 3. After collection, it will be discharged through the water outlet 6. The remaining product after dehydration falls to the bottom of the inner cylinder 2 and is discharged through the discharge port 5. Simultaneously, the upper and lower hydraulic cylinders 42 are started, driving the upper and lower collars 424 to move relative to each other to the middle position of the support rod 44. This drives the upper and lower sets of rotating rods 43 to rotate accordingly under the fulcrum of the support rod 441. Then, the multiple arc plates 431 are moved inward and outward, that is, the distance between them and the inner wall of the inner cylinder 2 can be adjusted to adjust the size of the dehydration space.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
