In this embodiment, the vibration assembly is two vibration motors 6 symmetrically installed on the left and right sides of the primary screening and dewatering trough 2;
[0017] In the primary screening and dewatering trough 2, a plurality of blocking bars 7 are installed at intervals from the front feeding end to the rear discharging end to prevent the particles from retreating toward the front feeding end; in the present embodiment, the specific installation structure of the blocking bars 7 in the primary screening and dewatering trough 2 includes: the blocking bars 7 are arranged along the width direction of the primary screening and dewatering trough 2, and the left, right and lower ends of the blocking bars 7 are in contact with the corresponding trough walls of the primary screening and dewatering trough and are welded and fixed, and the blocking bars 7 are arranged to be gradually inclined from the lower end to the upper end toward the rear discharging end of the primary screening and dewatering trough, so that the materials in the primary screening and dewatering trough 2 will not be hindered from climbing the slope from the front feeding end to the rear discharging end, and the particles that have crossed the blocking bars 7 forward will be effectively prevented from retreating backward, so as to avoid the dehydrated dry particles from retreating to the front feeding end of the primary screening and dewatering trough and mixing with the high-moisture particles at the front feeding end, thereby ensuring the particle dehydration efficiency;
[0018] The secondary screening trough 3 is fixedly installed on the rear discharge end of the primary screening and dewatering trough 2, the front discharge end of the secondary screening trough 3 is connected to the rear discharge end of the primary screening and dewatering trough 2, the trough bottom plate of the secondary screening trough 3 is uniformly distributed with secondary screening meshes 8 with a larger diameter than the primary screening meshes 5, an oversize discharge port 9 is arranged at the rear discharge end of the secondary screening trough 3, and a undersize material aggregate discharge trough 10 that can receive qualified particles screened out from the secondary screening meshes 8 of the secondary screening trough 3 is arranged directly below the secondary screening trough 3, the rear end of the undersize material aggregate discharge trough 10 is provided with a discharge port 11, and the trough bottom plate of the undersize material aggregate discharge trough 10 is The water tank 1 is tilted from all sides to the discharge port 11, which is convenient for discharging; the top of the water tank 1 is open to form a water tank inlet that can receive the particles screened out and the water removed from the primary screening and dehydration tank 2, a slag discharge port 12 is provided at the lower part of the water tank 1, and the bottom plate of the water tank 1 is tilted from all sides to the slag discharge port 12; a filter box 13 is provided in the water tank 1, and the filter box 13 is provided with a filter box inlet connected to the inside of the water tank 1, a filter screen 14 is provided at the filter box inlet, and a filter box outlet 15 connected to an external water pump is also provided on the filter box 14; an overflow port 16 is provided at the upper part of the water tank 1, and the overflow port 16 is connected to the buffer water tank 17;
[0019] The working principle of the utility model is as follows:
[0020] Pour the water-containing mixed particles granulated by the plastic recycling granulation production line into the front feeding end of the primary screening and dewatering trough 2, and then start the vibration motor 6. Under the vibration action of the vibration motor 6, the water-containing mixed particles entering the primary screening and dewatering trough 2 will slowly climb toward the rear discharging end. In the process of the water-containing mixed particles moving from the front feeding end to the rear discharging end in the primary screening and dewatering trough 2, the small-sized particles in the water-containing mixed particles will fall from the primary screening mesh of the primary screening and dewatering trough 2 into the water tank 1 below. At the same time, the water in the water-containing mixed particles will also be separated from the vibration. A part of the water separated from the particles falls directly from the primary screening mesh 5 into the water tank 1, and the other part of the water flows out from the front feeding end of the primary screening and dewatering trough 2 and falls into the water tank 1. Due to the primary screening and dewatering trough 2 is at an elevation angle of 3 to 5 degrees, ensuring that during the process of primary screening and dehydration of particles by the primary screening and dehydration tank 2, the released water flows downward to the front feeding end of the primary screening and dehydration tank 2 under the action of gravity, and does not flow to the rear discharging end of the primary screening and dehydration tank 2, thereby effectively preventing the released water from being reabsorbed by the low-moisture mixed particles moved to the rear discharging end of the primary screening and dehydration tank 2, thereby ensuring the dehydration efficiency; after the released water and small-sized particles enter the water tank, the small-sized particles will be deposited in the lower layer, and the small-sized particles can be discharged from the slag discharge port 12 of the water tank 1, and the water in the water tank 1 can be discharged through the external water pump connected to the filter box outlet, and since the filter box inlet of the filter box 13 is provided with a filter screen 14, impurities in the water can be effectively filtered, so the external water pump is effectively protected;
[0021] The low-moisture mixed particles screened out from the discharge end of the primary screening and dewatering trough 2 will enter the secondary screening trough 3. Similarly, under the vibration action of the vibration motor 6, the low-moisture mixed particles entering the secondary screening trough 3 will move backward. In the process of the low-moisture mixed particles moving backward, the large-sized particles in the low-moisture mixed particles are retained on the secondary screening trough 3 and discharged from the screened material discharge port 9, and the qualified particles that meet the size fall from the secondary screening mesh 8 to the screened material aggregate discharge trough 10, and then are discharged through the discharge port 11.
[0022] The beneficial effects of the utility model are as follows: (1) It integrates the dehydration function and the screening function, and performs dehydration and screening by vibrating the screening trough, which is not prone to blockage and jamming. It has high stability in use and high dehydration efficiency. It has a simple structure, is relatively inexpensive, and has low maintenance costs in the later stage of the equipment, which reduces the production and use costs of the enterprise. (2) It has a secondary screening function, which can screen out large and small particles, thereby picking out qualified particles that meet the size; (3) By setting the material blocking horizontal bar, the dehydrated particles are prevented from retreating backwards, and the dehydrated dry particles are prevented from retreating to the front feed end of the primary screening and dehydration trough and mixing with the high-moisture particles at the front feed end, thereby ensuring the dehydration efficiency.
