DETAILED DESCRIPTION

[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0020] like Figures 1 to 4 As shown, the present invention can be implemented through the following embodiments: a papermaking wastewater treatment equipment, including a base 1, a support frame 2 and a support frame 3 are provided on the base 1, a purification box 4 is installed on the support frame 2, a water inlet 41 is provided on the purification box 4, a motor 42 is installed on the purification box 4, a rotating shaft 43 is connected to the motor 42, a stirring piece 431 is installed on the rotating shaft 43, a medicine storage box 44 is provided on the purification box 4, a purification box 5 is installed on the support frame 2 3, the purification box 2 5 is divided into a cover 51 and a water storage body 52, a water outlet 521 is provided on the water storage body 52, a connecting part 45 is provided on the purification box 4, a valve 451 is provided on the connecting part 45, a connecting water pipe 6 is installed between the cover 51 and the connecting part 45, a filter screen 53 is installed between the cover 51 and the water storage body 52, a connecting pipe 54 is provided on the side of the purification box 2 5, and a collecting box 7 is installed at the connecting pipe 54.

[0021] The base 1, support frame 1 2 and support frame 2 3 are used to provide installation locations for purification box 1 4 and purification box 2 5, and at the same time prevent purification box 1 4 and purification box 2 5 from being affected by ground water and rusting.

[0022] A medicine storage box 44 is provided on the purification box 4, and a flocculant can be installed in the medicine storage box 44. The flocculant can be automatically added when treating papermaking wastewater to flocculate the impurities or suspended particles in the papermaking wastewater; the connecting water pipe 6 facilitates the delivery of the preliminarily treated wastewater from the purification box 4 to the purification box 2 5; the connecting part 45 of the purification box 4 is used to connect the connecting water pipe 6, and the valve 451 installed in the connecting water pipe 6 is used to block the connecting part 45 to prevent the wastewater from flowing into the purification box 2 5 before the flocculant is completed.

[0023] The filter screen 53 in the purification box 2 5 is used to filter the flocs produced in the purification box 1 4 , and the collecting box 7 is used to collect the flocs.

[0024] like Figures 1 to 3 As shown, a mounting groove 411 is provided at the water inlet 41, and a filter cartridge 412 is mounted on the mounting groove 411. The filter cartridge 412 is used to perform preliminary filtration on the paper scraps remaining in the papermaking wastewater, so as to facilitate the recovery of the paper scraps and fibers.

[0025] like Figure 4 As shown, one side of the medicine storage box 44 is provided with a transparent glass plate 441. The transparent glass plate 441 is provided to facilitate observation of the amount of flocculant in the medicine storage box 44, so that the staff can decide whether to replenish the flocculant.

[0026] like Figure 1 and Figure 2As shown, the height of support frame 2 3 is lower than that of support frame 1 2. The height difference facilitates the flow of wastewater in purification box 1 4 into purification box 2 5, facilitating the next purification step, eliminating the use of a water pump, and simplifying the structure.

[0027] like Figure 2 As shown, the bottom of the purification box 1 4 is inclined toward the connection water pipe 6, and the bottom of the purification box 2 5 is inclined toward the water outlet 521. The bottoms of the purification box 1 4 and the purification box 2 5 are inclined to facilitate the treated wastewater to flow out by gravity.

[0028] like Figure 1 and Figure 3 As shown, a control box 71 is provided on the connecting pipe 54, and a moving block 711 and a telescopic column 712 are mounted on the control box 71. The control box 71 is used to control the moving block 711 via the telescopic column, which is used to seal the connection between the collection box 7 and the cover 51, preventing unfiltered wastewater in the purification box 2 5 from flowing into the collection box 7.

[0029] like Figure 1 and Figure 3 As shown, a mounting portion 55 is provided next to the purification box 2 5, a push rod motor 8 is installed in the mounting groove 411, and a push block 81 is installed on the push rod motor 8. The mounting portion 55, the push rod motor 8 and the push block 81 are arranged above the filter 53. The push block 81 is provided on the push rod motor 8 to push the flocculent accumulated on the filter 53 into the collection box 7, facilitating the next papermaking wastewater treatment and extending the service life of the filter 53.

[0030] like Figure 1 and Figure 3 As shown, a chute 72 is provided in the collection box 7, and a pull box 9 is installed in the chute 72. The flocs collected by the collection box 7 are accumulated in the pull box 9. The arrangement of the pull box 9 facilitates workers to handle the flocs collected in the collection box 7, facilitates the collection of flocs by the collection box 7, reduces the standby time of the equipment, and improves the working efficiency of the equipment.

[0031] The working principle of the present invention is as follows: papermaking wastewater enters the purification box 4 from the water inlet pipe, and then the larger paper scraps and fibers in the wastewater are preliminarily filtered through the filter cartridge 412 for easy recycling. After the medicine storage box 44 is opened, flocculant is added into the purification box 4, the motor 42 is started and driven to rotate, and the stirring blade 431 stirs the wastewater so that the impurities and suspended particles in the wastewater react with the flocculant to produce flocs.

[0032] After the flocculent floccules are coagulated, the valve 451 is opened, and the wastewater carrying the flocculent floccules flows into the purification box 2 5 through the connecting water pipe 6, and the flocculent floccules are filtered by the filter 53. The filtered wastewater flows out from the outlet pipe at the bottom of the purification box 2 5, and the flocculent floccules are swept into the collection box 7 by the push block 81.

[0033] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.

[0034] Although various terms are used in this document, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.
