Technical Field

[0001] This application relates to the technical field of plastic granulation, and particularly relates to a dehydration device with a sieving function. Background Art

[0002] After plastic granulation production using the extrusion process, it will enter water for cooling treatment, and then the plastic particles will be dehydrated and then sieved. In the prior art, the dehydration and sieving of plastic particles are usually carried out as two independent processes, first dehydrating and then sieving, using a single dehydration device or sieving device. The equipment occupies a relatively large area horizontally, and a transfer device needs to be added for transfer, increasing the cost of material transfer. Therefore, further improvement is needed. Utility Model Content

[0003] In order to reduce the possibility of large equipment floor area, this application provides a dehydration device with a sieving function.

[0004] A dehydration device with a sieving function provided by this application adopts the following technical solutions:

[0005] A dehydration device with a sieving function includes a frame, a dehydration bin arranged on the frame, a screen arranged in the dehydration bin, a vibration motor arranged outside the dehydration bin, and a water collection and drainage structure arranged on the dehydration bin. An inlet pipe is fixedly penetrated through the upper part of the dehydration bin. The upper middle part of the dehydration bin is used to accommodate the material to be processed for dehydration. A plurality of filter meshes are arranged in the upper middle part of the dehydration bin, and adjacent filter meshes are communicated. The dehydration bin is provided with a stirring assembly for stirring the material and a heating assembly for heating and dehydrating the material. The screen is arranged in the lower middle part of the dehydration bin. A plurality of screens are arranged and spaced in the dehydration bin. A plurality of discharge pipes corresponding to the screens are fixedly penetrated through the outer peripheral wall of the dehydration bin. The water collection and drainage structure is used to collect and discharge the water after dehydration and sieving. The water collection and drainage structure includes a water collection tank arranged on the bottom wall of the dehydration bin and a drain pipe fixedly penetrated through the water collection tank and the dehydration bin.

[0006] By adopting the above technical solutions, after the material with moisture enters through a plurality of filter meshes, at this time, the water molecules fall along the filter meshes and pass through the screen to reach the lower water collection tank, and then are discharged through the drain pipe. When the material is on the filter mesh, it is first dispersed by the stirring assembly to increase the heat transfer between it and the heating assembly, thereby accelerating the dehydration efficiency of the material and reducing the water content in the material when it falls on the lower screen. And by arranging both the screen and the dehydration in the dehydration bin, the floor area in the horizontal direction can be reduced, and the need for adding a transfer device for transfer can be reduced, so as to reduce the cost of material transfer.

[0007] Preferably, the dehydration bin includes an outer bin disposed on the frame and an inner bin disposed inside the outer bin. A first driving member for driving the inner bin to rotate around the axis of the outer bin is provided on the outer bin.

[0013] Preferably, the stirring assembly further includes a scraping plate disposed on the stirring shaft, and a gap for the material to pass through is left between the lower surface of the scraping plate and the screen.

[0014] By adopting the above technical solution, by providing a scraping plate, since it is disposed on the stirring shaft, it can rotate along with the stirring shaft when the stirring shaft rotates. Since a gap for the material to pass through is left between the scraping plate and the upper surface of the screen, the operation of leveling some materials with more accumulation can be performed to reduce the possibility of affecting the subsequent screening effect due to excessive accumulation.

[0015] Preferably, the screen is inclined in the direction close to the discharge pipe. Sliders are convexly provided at both ends of the scraping plate. A sliding groove for slidably connecting one of the sliders is provided on the stirring shaft along its height direction, and an annular groove for slidably connecting the other slider is wound around the inner wall of the outer bin. The radial direction of the annular groove is parallel to the diameter direction of the screen.

[0016] By adopting the above technical solution, the screen is inclined towards the direction close to the discharge pipe so as to discharge the screened material. Since the scraper is arranged on the stirring shaft, in order to reduce the influence of the inclined screen on the arranged scraper, a slider, a corresponding chute and an annular groove are provided to change along with the inclination of the screen during rotation.

[0017] Preferably, the heating assembly includes a first conveying pipe coaxially sleeved on the stirring shaft and a second conveying pipe for conveying hot air passing through the outer bin and the inner bin. The first conveying pipe is rotatably connected to the second conveying pipe. The stirring rod is fixedly arranged through the outer peripheral wall of the first conveying pipe to communicate with the first conveying pipe. The stirring rod is hollow, and air outlet holes are formed through the outer peripheral wall of the stirring rod.

[0018] By adopting the above technical solution, the first conveying pipe and the second conveying pipe are provided for conveying hot air. The stirring rod is hollow, and air outlet holes are formed through the outer peripheral wall of the stirring rod. When stirring, hot air is conveyed to the material to perform heat transfer between the adhered water molecules for evaporation, so as to reduce the water molecules contained on the surface of the material.

[0019] Preferably, the heating assembly further includes a heating pipe. An installation chamber for installing the heating pipe is arranged in the outer bin, and the heating pipe is wound in a spiral shape along the axis of the outer bin.

[0020] By adopting the above technical solution, the material is heated through the heating pipe.

[0021] In summary, the utility model has the following beneficial effects:

[0022] After the material with moisture enters through several filter meshes, at this time, the water molecules fall along the filter meshes and pass through the screen to reach the water collecting tank below and then are discharged through the drain pipe. When the material is on the filter mesh, it is first dispersed by the stirring assembly to increase the heat transfer between it and the heating assembly, thereby accelerating the dehydration efficiency of the material and reducing the water content in the material when it falls on the screen below. And by arranging the screen and dehydration in the dehydration bin, the floor area in the horizontal direction can be reduced, and the need for additional transfer equipment for transfer can be reduced, so as to reduce the cost of material transfer.
