DETAILED DESCRIPTION

[0021] In order to make the above features and advantages of the present invention more understandable, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0022] refer to Figures 1 to 4

[0023] A wastewater treatment device for resin production, comprising a box body 10, a water inlet pipe 11 for resin wastewater is arranged on the top of the box body, a detachable filter screen 20 is obliquely arranged on the upper part of the inner cavity of the box body, so as to better filter the resin wastewater; a movable seat 30 driven by a driving mechanism to achieve lateral movement is arranged on the upper side of the filter screen, a liftable scraper 40 is elastically connected to the lower side of the movable seat, a notch 12 for the movable seat to pass through is arranged on the side wall of the box body at the high end of the filter screen, and an impurity receiving groove 50 is arranged on the outer side wall of the box body corresponding to the notch, so as to receive impurities scraped from the filter screen by the scraper.

[0024] In this embodiment, a fixing bracket 60 is installed on the upper outer wall of the box body corresponding to the notch, and a pair of guide rails 61 parallel to the filter screen are installed between the fixing bracket and the other side wall of the box body. The guide rails avoid the water inlet pipe output port, and the front and rear sides of the movable seat are respectively provided with sliding sleeves 31 that slide with the guide rails, so that the driving mechanism drives the movable seat to move laterally along the guide rails.

[0025] In this embodiment, in order to drive the moving seat to move, the driving mechanism includes a first pulley 71 installed on the fixed frame and located above the guide rail, a vertical motor 72 is installed on the outer wall of the other side of the box, a second pulley 73 is installed on the output end of the vertical motor, a transmission belt 74 is sleeved between the first pulley and the second pulley, and a connecting block 32 fixed to one side of the transmission belt is fixed on the upper side of the moving seat. Thus, when the vertical motor rotates forward, the moving seat is driven to move toward the side of the notch, and when the vertical motor rotates reversely, the moving seat is driven to move toward the side of the historical motor. When the scraper is moving, the water inlet pipe stops inletting water to prevent wastewater from affecting the operation of the driving mechanism.

[0026] In this embodiment, the fixing frame and the upper wall on the other side of the box body are both provided with position sensors 75, so that the vertical motor changes direction after the moving seat touches the position sensor.

[0027] In this embodiment, in order to enable the scraper to contact the filter when the moving seat moves toward the notch, and not to contact the filter when the scraper moves back to the side of the vertical motor, so as to avoid bringing impurities to the low position of the filter, a vertical cylinder 76 is vertically installed on the moving seat, and a fixed plate 77 driven to rise and fall by the vertical cylinder is provided on the lower side of the moving seat. The lower side of the fixed plate is connected to the scraper via a plurality of springs 78, so that the scraper can better contact the filter through the springs.

[0028] In this embodiment, the fixed plate is fixed with a guide rod 79 slidably connected with the movable seat, so as to better realize the fixed plate driving the scraper to rise and fall. The lower side of the scraper is provided with a plurality of rubber plates 41 with high wear resistance from left to right to scrape away impurities.

[0029] In this embodiment, in order to facilitate the removal and cleaning of the filter, the front and rear side walls of the box are transversely provided with oblique slots 13, and the front and rear sides of the filter are slidably connected to the corresponding oblique slots, so that the filter can be removed from the notch to clean the impurities blocked in the filter mesh or replace the filter. The mesh of the filter can be 0.5-1 mm, and the angle between the filter and the horizontal plane is 10°-18°.

[0030] In this embodiment, in order to filter out the moisture in the impurities and return the filtered water to the box, support blocks 51 are provided on both side walls of the impurity receiving tank, and a filter frame 52 with a handle on the upper part is placed on the upper side of the support block in the impurity receiving tank. The filter frame is composed of a filter net and a frame, so that the impurities can be taken out and cleaned centrally and the moisture can be filtered through the filter frame; a reflux pipe 53 leading to the box is installed at the bottom of the impurity receiving tank, and the waste water is allowed to flow back into the box through the reflux pipe.

[0031] In this embodiment, a water pump 14 is installed on the other side of the box body, and a water pump 15 is installed on the water pump. The output end of the water pump is connected to the activated carbon adsorption box so that smaller impurities in the resin wastewater can be adsorbed by the activated carbon, and the adsorbed liquid is disinfected by a disinfection device arranged in the activated carbon adsorption box. The disinfected liquid can be treated through subsequent distillation, condensation and other processes.

[0032] After the filter has been used for a period of time, the impurities on the filter can be regularly moved to the impurity receiving groove by controlling the scraper. This helps to avoid excessive accumulation of impurities on the filter, causing clogging of the filter, affecting the filtering effect and filtering efficiency, and prolonging the service life of the filter.

[0033] If the words "first", "second" and the like are used in the above-mentioned utility model to limit components, those skilled in the art should know that the use of "first" and "second" is only for the convenience of description to distinguish the components. Unless otherwise stated, the above-mentioned words have no special meaning.

[0034] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the fixed connection to each other can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0035] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0036] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated forming process.

[0037] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
