DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In the process of paper production, a large amount of waste water will be generated. In order to avoid the waste of this waste water, it is necessary to treat this waste water. Therefore, a waste water recovery device is needed to recycle this waste water. The utility model treats the waste water through a waste water recovery device. The waste water is sent into a treatment box 1, and the waste water is filtered from the bottom of the filter screen 10. Then, clean water flows out of the filter screen 10 and flows out through the water outlet 4. The device can treat the impurities remaining in the treatment process and the waste water mixed with the impurities. By setting a movable filter screen 10, more waste water is filtered, and the impurities can be squeezed out to squeeze the water mixed with the impurities for filtration.

[0020] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a papermaking wastewater recovery device for papermaking, comprising a treatment box 1, one side of the treatment box 1 is fixedly connected with a water inlet pipe 6, one side of the treatment box 1 is provided with a water outlet 4, the water outlet 4 is located directly above the water inlet pipe 6, the inner wall of the treatment box 1 is slidably connected with a filter screen 10, the other side of the treatment box 1 is fixed with a connecting frame 2, the top of the connecting frame 2 penetrates the treatment box 1 and is provided with a lifting mechanism 3, the lifting mechanism 3 includes a screw rod 301 rotatably connected to the inner wall of the top end of the connecting frame 2, and the top of the connecting frame 2 is fixed with a filter screen 10. Motor 305, the output end of motor 305 passes through the connecting frame 2 and is fixed to the top of the screw rod 301, the outer wall of the screw rod 301 is screwed with a connecting sleeve 302, the connecting sleeve 302 passes through the processing box 1 and is fixed to the top of the filter screen 10, the outer wall of the connecting sleeve 302 is fixed with a limiting plate 303, the inner wall of the top of the connecting frame 2 is fixed with a limiting rod 304, the limiting rod 304 passes through the limiting plate 303 and the top of the processing box 1, and a baffle 11 is fixed on one side of the filter screen 10, and the baffle 11 is located on one side of the water outlet 4 for shielding the water outlet 4.

[0021] It should be noted that the motor 305 drives the screw rod 301 to rotate, and the rotation of the screw rod 301 drives the connecting sleeve 302 to move downward, and the downward movement of the connecting sleeve 302 drives the filter screen 10 to move downward, and the filter screen 10 can filter the wastewater entering the treatment box 1. In addition, when there is a lot of water remaining in the treatment box 1, the filter screen 10 moves downward, so that the filtered water is located above the filter screen 10, and the impurities can be squeezed out to squeeze the water out. When the filter screen 10 moves downward, the baffle 11 also moves downward, so that the water outlet 4 is less blocked, so that the filtered water can flow out from the water outlet 4, and the wastewater in the treatment box 1 can be better treated.

[0022] like Figure 1 and Figure 4 As shown, a box door 7 is installed at the other end of the treatment box 1, and a sealing strip is installed on the outer wall where the box door 7 and the treatment box 1 are in contact. A mounting plate 12 is fixed to the bottom end of the connecting sleeve 302, and a connecting port 13 is provided on the mounting plate 12. A rotating rod 14 is rotatably connected to the top of the filter screen 10, and a connecting block 15 is fixed to the outer wall of the rotating rod 14. The rotating rod 14 and the connecting block 15 are adapted to the connecting port 13. A retaining frame 5 is fixed to the outside of the water outlet 4 on one side of the treatment box 1, and a valve is installed on the water inlet pipe 6. The valve is a one-way valve, and wastewater can enter the treatment box 1 but cannot go out from the water inlet pipe 6. A sewage box 9 is plugged into the inner wall at the bottom of the treatment box 1, and a water inlet is provided on one side of the sewage box 9, and the water inlet coincides with the water inlet end of the water inlet pipe 6. A controller 8 is installed at one end of the treatment box 1, and the controller 8 is electrically connected to the motor 305.

[0023] It should be noted that the motor 305 drives the screw rod 301 to reverse, the screw rod 301 rotates to drive the connecting sleeve 302 to move upward, and the connecting sleeve 302 moves upward to drive the filter screen 10 to move upward. When it moves to the position of the box door 7, the box door 7 can be opened, and then the rotating rod 14 is rotated. The rotating rod 14 drives the connecting block 15 to rotate, and the connecting block 15 rotates so that the rotating rod 14 and the connecting block 15 coincide with the connecting port 13. In this way, the filter screen 10 can be removed from the bottom end of the mounting plate 12, which is convenient for replacing the filter screen 10. In addition, the impurities in the wastewater entering the treatment box 1 are stored in the sewage outlet box 9, and the impurities can be taken out by taking out the sewage outlet box 9.

[0024] Working principle: During use, the motor 305 drives the screw rod 301 to rotate, and the rotation of the screw rod 301 drives the connecting sleeve 302 to move downward, and the downward movement of the connecting sleeve 302 drives the filter screen 10 to move downward, and the filter screen 10 can filter the wastewater entering the treatment box 1. When the filter screen 10 moves downward, the baffle 11 also moves downward, so that the water outlet 4 is less blocked, so that the filtered water can flow out from the water outlet 4, and the filter screen 10 can squeeze the impurities and squeeze out the water, so as to better treat the wastewater in the treatment box 1.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
