DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0031] like Figures 1 to 3 As shown, a raw material conveying structure of a plastic raw material dehydration device includes a transfer tank 1 and a feed port 2 arranged on the transfer tank 1, the feed port 2 is connected to a cleaning machine, and the output end of the cleaning machine is connected to the feed port 2 through a pipeline, so as to directly convey the raw materials salvaged from the cleaning machine directly to the transfer tank 1, so as to collect part of the cleaning water salvaged together with the raw materials, reduce the consumption of water resources in the raw material transportation process, improve the recycling rate of water resources, and save production costs. The raw material conveying structure of the plastic raw material dehydration device also includes:

[0032] The centrifugal dehydration component 5 disposed in the material transfer tank 1 is rotated, and the centrifugal dehydration component 5 is used for preliminary centrifugal dehydration of the raw material.

[0033] The drain pipe 4 is fixed on the transfer tank 1. The drain pipe 4 is arranged to recover the collected water resources and transport them back to the cleaning machine through the water pump again. It can not only greatly reduce the waste of water resources, but also perform preliminary dehydration of the transported raw material particles, reduce the moisture carried by the raw material particles, and reduce the influence of moisture on the subsequent dehydration efficiency of the raw material particles.

[0034] A variable speed motor 10 is used to drive the centrifugal dehydration element 5 to rotate.

[0035] A discharge chute 7 is fixedly connected to a discharge port 6 provided on the transfer tank 1, and a conveying portion 8 for conveying raw material particles is provided at the outlet of the discharge chute 7. One end of the conveying portion 8 is connected to a dehydrator, so that the raw material particles after preliminary dehydration can be directly conveyed to the dehydrator.

[0036] The centrifugal dehydration element 5 comprises:

[0037] The vertical shaft 56 disposed in the material transfer tank 1 is rotated.

[0038] A dewatering screen plate 51 is arranged on the vertical shaft 56 and is used to lift the raw material particles.

[0039] At least three partition plates 52 are fixed on the dewatering sieve plate 51, and the partition plates 52 divide the dewatering sieve plate 51 into at least three solid-liquid separation areas 53, and an opening is provided in the solid-liquid separation area 53 near the boundary of the dewatering sieve plate 51, so that when the solid-liquid separation area 53 passes through the discharge port 6, the raw material particles are discharged into the discharge port 6 through the opening.

[0040] At least one resistance increasing plate 54 is arranged in the solid-liquid separation area 53. The resistance increasing plate 54 and the solid-liquid separation area 53 together form a concave groove 55 for carrying raw material particles. The inner diameter of the sieve holes on the dewatering screen plate 51 and the resistance increasing plate 54 is smaller than the diameter of the raw material particles.

[0041] The raw material particles entering the transfer tank 1 through the feed port 2 will first fall into the concave grooves 55 in different solid-liquid separation areas 53, and by controlling the variable speed motor 10 to rotate at a relatively low speed, the raw material particles are subjected to relatively small centrifugal force, so that the raw material particles will not jump out of the concave grooves 55. The water droplets attached to the raw material particles can also be separated and gathered to the bottom of the transfer tank 1 through the sieve holes on the dewatering sieve plate 51 and the resistance increasing plate 54, so as to realize the centralized recovery of water, so as to facilitate repeated transportation back to the cleaning machine, thereby reducing the water consumption of the cleaning machine.

[0042] In this embodiment, the feed port 2 is located on the upper surface of the transfer tank 1, and the discharge port 6 is located on the side wall of the transfer tank 1. The angle between the discharge port 6 and the feed port 2 in the circumferential rotation direction of the dewatering screen plate 51 is greater than 180°, which can prevent the raw material from splashing into the discharge port 6 due to collision when falling into the transfer tank 1, thereby affecting the initial dehydration effect of the raw material particles. It can also prevent the water carried by the raw material particles when they are salvaged from leaking out of the discharge port 6, thereby affecting the water resource recovery rate.

[0043] In this embodiment, the bottom of the transfer tank 1 is a conical tank bottom 9, and the shape of the conical tank bottom 9 is a truncated cone. Such a conical tank bottom 9 can make the water droplets or water flows falling on its surface converge to the boundary of the bottom of the transfer tank 1, so that the drain pipe 4 can efficiently discharge the collected water, thereby improving the recovery efficiency and effect of water resources and avoiding water accumulation in the transfer tank 1.

[0044] In this embodiment, the boundary of the dewatering sieve plate 51 is flush with the lower edge of the discharge port 6, and the gap between the boundary of the dewatering sieve plate 51 and the inner wall of the transfer tank 1 is smaller than the diameter of the raw material particles. With such a design, the centrifugal force on the raw material particles in the concave groove 55 is increased by accelerating the rotation speed of the centrifugal dewatering component 5, so that the raw material particles exceed the concave groove 55 under the push of centrifugal force, and fall into the solid-liquid separation area 53, and slide along the dewatering sieve plate 51 to its boundary, and when passing the discharge port 6 in the solid-liquid separation area 53, the raw material particles pass through the open opening, the discharge port 6 and the discharge chute 7 in the solid-liquid separation area 53 under the push of centrifugal force, and are finally transported to the conveying part 8, and the raw material particles after preliminary dehydration are transported to the dewatering machine.

[0045] In this embodiment, the raw material conveying structure of the plastic raw material dehydration device further includes a feed enclosure 3 fixed to the outside of the feed port 2 .

[0046] The feed enclosure 3 can prevent the raw materials from splashing out when loading, and will not block the user from observing the operation status in the transfer tank 1.

[0047] In this embodiment, the conveying unit 8 includes:

[0048] A conveying frame 81 is arranged at the lower end of the unloading chute 7 .

[0049] A conveying member 83 is rotatably arranged in the conveying frame 81. The conveying member 83 includes an active roller and a driven roller rotatably arranged at both ends of the conveying frame 81, and a conveying belt rotatably mounted on the active roller and the driven roller. The surface of the conveying belt is also evenly distributed with sieve holes. The inner diameter of the sieve holes is smaller than the diameter of the raw material particles, so that the raw materials falling on its upper surface can remain vertically transparent, thereby improving the initial dehydration effect of the raw materials.

[0050] The conveying motor 82 is used to drive the conveying member 83 to operate. The conveying motor 82 is fixed on the conveying frame 81, and the output end of the conveying motor 82 is fixedly connected to one end of the active roller, so as to drive the active roller to rotate and drive the conveying belt to rotate, so as to realize the conveying of raw materials, so as to facilitate the preliminary dehydrated raw materials to be transported from the outlet of the unloading chute 7 on the transfer tank 1 to the dehydrator, and during the transportation process, the permeability of the conveying belt can also be used to improve the drying effect of the raw materials, and by reducing the moisture attached to the surface of the raw materials, the influence of moisture on the dehydration effect of the dehydrator can be reduced.

[0051] The above description is only the preferred embodiment of the utility model, and the parts not described in the utility model can be implemented by adopting or drawing on existing technologies. Of course, the above description is not a limitation of the utility model, and the utility model is not limited to the above examples. The changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the utility model should also fall within the protection scope of the utility model.
