DETAILED DESCRIPTION
[0020] This specific embodiment is a wastewater treatment device for recycling waste plastic bottles with a filtering function, and its structural schematic diagram is shown in FIG. Figure 1-Figure 4 As shown, it includes a box body 1, a feed pipe 2 is fixedly connected to the top surface of the box body 1, two transmission rollers 3 are rotatably connected to the inner cavity of the box body 1 near the top surface, the same conveyor belt 4 is transmission-connected between the two transmission rollers 3, and a plurality of leakage holes are opened on the conveyor belt 4, a partition 5 is fixedly connected to the inner wall of the box body 1 near the left side, an extrusion assembly is arranged on the left side of the partition 5, a drainage assembly is arranged on the bottom surface of the inner cavity of the box body 1, a rotating shaft 19 is rotatably connected to the inner wall of the box body 1, a mixing rod 20 is fixedly connected to the side wall of the rotating shaft 19, and a filter is arranged on the lower side of the conveyor belt 4 in the inner cavity of the box body 1.
[0021] like Figure 2 and Figure 4 As shown, the extrusion assembly includes a baffle 6 arranged on the left side of the partition 5, the left side wall of the baffle 6 passes through the box body 1 and is movably connected thereto, a bracket 7 is fixedly installed on the left side wall of the box body 1, a first push rod 8 is fixedly installed on the side wall of the bracket 7, the output end of the first push rod 8 is fixedly connected to the baffle 6, the left side wall of the partition 5 is fixedly connected to an inclined plate 10, a discharge trough is provided on the left side wall of the box body 1 on the upper side of the inclined plate 10, the inclined plate 10 passes through the discharge trough, a plurality of through holes 9 are provided on the side wall of the partition 5, a second push rod 11 is fixedly connected to the top surface of the box body 1, and the output end of the second push rod 11 passes through the box body 1 and is fixedly connected to a pressure plate 12.
[0022] Among them, a card groove corresponding to the baffle 6 is opened on the side wall of the partition 5. When the baffle 6 is in the initial state, the baffle 6 is stuck in the card groove, which can not only improve the sealing performance, but also disperse the pressure when the pressure plate 12 is pressed down, thereby increasing the stability of solid-liquid separation of particulate impurities.
[0023] like Figure 2 As shown, the drainage assembly includes a pump 16 installed on the bottom surface of the inner cavity of the box body 1, and the side walls of the pump 16 are respectively fixedly connected with a water inlet pipe 17 and a water outlet pipe 18, and the water outlet pipe 18 runs through the box body 1.
[0024] Specifically, the water inlet pipe 17 adopts a three-way pipe, one end of which extends between the partition plate 5 and the sealing plate 15, and the other end is located in the inner cavity of the box body 1, so as to discharge the waste water in the liquid storage cavity and the box body 1 at the same time.
[0025] like Figure 2 As shown, the filter element includes a filter plate 13 arranged in the inner cavity of the box body 1. A rectangular groove is opened on the right side wall of the box body 1. The filter plate 13 passes through the rectangular groove and is fixedly connected to a limit plate 14. Two handles are fixedly connected to the side wall of the limit plate 14.
[0026] Specifically, the pore size on the filter plate 13 is 60 to 100 meshes. The pore size in this range can filter smaller particles and impurities, effectively improving the cleanliness of the collected waste liquid.
[0027] like Figure 3 As shown, a motor 21 is installed on the rear side wall of the box body 1, the rear end of the rotating shaft 19 is fixedly connected to the output end of the motor 21, and sprockets 22 are fixedly connected at the rear ends of the rotating shaft 19 and the driving roller 3, respectively, and a chain 23 is drivingly connected between the two sprockets 22.
[0028] Among them, the transmission structures adopted in this scheme all belong to the linkage of existing commonly used structures, which can mainly realize the reasonable distribution of output power. Therefore, they will not be described in detail in this scheme.
[0029] like Figure 2 As shown, a sealing plate 15 is fixedly connected between the right side wall of the partition 5 and the box body 1 , a liquid storage cavity is formed between the sealing plate 15 and the partition 5 , and a water inlet pipe 17 passes through the sealing plate 15 .
[0030] Specifically, the space between the sealing plate 15 and the partition 5 can be used to store moisture generated when squeezing granular impurities. On the one hand, it can prevent moisture from overflowing outside the box 1 and causing a large amount of odor. On the other hand, it can collect waste liquid and discharge it with the waste liquid from the box 1, thereby increasing the treatment effect of the waste liquid.
[0031] Working principle: first, the waste water collected when the plastic bottle is crushed is discharged into the feed pipe 2, and then the motor 21 is started. The output end of the motor 21 drives the rotating shaft 19 and the lower sprocket 22 to rotate at the same time, and the rotating shaft 19 drives the mixing rod 20 to rotate, and the waste liquid collected in the box body 1 is mixed to avoid the precipitation of impurities in the waste liquid, which will cause hidden dangers to the movement of the pump 16. The lower sprocket 22 drives the upper sprocket 22 to rotate through the chain 23, and the upper sprocket 22 drives the conveyor belt 4 to run through the transmission roller 3. The waste liquid falling on the conveyor belt 4 falls into the box body 1 through the leakage hole, and the granular impurities fall on the baffle 6 through the conveyor belt 4. When the granular impurities on the baffle 6 accumulate more, the second push rod 11 is first started to drive the pressing plate 12 to move downward, and the pressing plate 12 squeezes the granular impurities. The water generated by the squeezing of the granular impurities enters the liquid storage cavity through the through hole 9. When the squeezing is completed, the second push rod 11 is reset, and the first push rod 8 drives the baffle 6 to open, so that the squeezed impurities fall on the inclined plate 10 for discharge;
[0032] When the wastewater in the box 1 accumulates to a certain extent, the pump 16 is started to discharge the wastewater for centralized purification. The discharged wastewater has a low content of particulate impurities, which is conducive to improving the subsequent purification rate.
[0033] All technical features in this embodiment can be freely combined according to actual needs.
[0034] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
