Technical Field

[0001] The utility model belongs to the technical field of papermaking wastewater treatment, in particular to a papermaking wastewater treatment device. Background Art

[0002] Papermaking wastewater is one of the main sources of industrial pollution in my country. It refers to the wastewater generated in the pulping and papermaking process, including pulping cooking waste liquid, washing wastewater, bleaching wastewater and paper machine white water.

[0003] In the process of realizing the utility model, the inventor found that there are at least the following problems in the technology: At present, when treating papermaking wastewater, one of the steps is to add flocculants into the wastewater to react with some harmful substances in it to produce floccules, which are then separated. However, the wastewater treatment equipment that performs this step usually requires manual skills to salvage the floccules after the floccules are produced, which is quite troublesome.

[0004] To this end, we proposed a papermaking wastewater treatment equipment to solve the above problems. Utility Model Content

[0008] A second motor is horizontally installed on one side wall of the treatment tank, and inner support shafts are rotatably connected on both sides of the inner cavity of the treatment tank. The output shaft of the second motor is coaxially connected to one of the inner support shafts, and the mixing dish is welded to the two inner support shafts respectively. An inner row pipe is connected to the bottom wall of the mixing dish, and a filter screen for filtering solid matter such as flocculants is installed at the opening on the top of the inner row pipe.

[0009] As a preferred embodiment, an inner oblique tube is fixedly connected to the bottom of the feeding tube, and the bottom of the inner oblique tube is located directly above the inner opening of the mixing dish; so that the inner oblique tube can add both the papermaking wastewater to be treated and the flocculant into the mixing dish.

[0010] As a preferred embodiment, the bottom frame is in a U-shape, and the first motor is vertically mounted on the bottom wall of the inner space of the bottom frame, so that the structure of the first motor remains stable.

[0011] As a preferred embodiment, the stirring blade has two blades symmetrically distributed on the transmission shaft, and the stirring blade is welded to the transmission shaft in one piece, so that the structure on both sides of the stirring blade remains stable.

[0012] As a preferred embodiment, an electric valve is installed on the inner discharge pipe, so that the discharge of wastewater can be controlled by controlling the electric valve.

[0013] As a preferred embodiment, a discharge pipe is connected to the center of the bottom wall of the treatment tank, and a valve is installed on the discharge pipe, so as to facilitate the control of the discharge of wastewater or flocculants.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] The papermaking wastewater treatment equipment, after adding wastewater and flocculant into the mixing dish through a feeding pipe, operates a first motor to fully stir the wastewater and flocculant with a stirring blade, thereby generating corresponding floccules, drives an electric valve on an inner discharge pipe to open, discharges the liquid, then removes the stirring blade from the mixing dish, and then drives a second motor to automatically pour out the remaining floccules by turning over the mixing dish, thereby realizing automatic discharge of solids after wastewater treatment, eliminating the trouble of manual treatment;

[0016] After the papermaking wastewater treatment equipment completes the papermaking wastewater treatment, the driving cylinder drives the stirring blade to rise and return it to its original position. At this time, the electric valve opens the inner discharge pipe to discharge the remaining wastewater in the mixing dish from the inner discharge pipe; then, the second motor is driven to drive the mixing dish and the two inner support shafts to flip a certain angle, so that the remaining flocculants in the mixing dish are poured out, and the flocculants are also discharged from the discharge pipe, thereby realizing the separation and automatic discharge of wastewater and flocculants.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 3 , a papermaking wastewater treatment device, comprising a treatment tank 1 and a wastewater treatment mechanism located on the treatment tank 1, a feeding pipe 2 is fixedly connected to one side of the top wall of the treatment tank 1, pillars 6 are welded to the four corners of the top wall of the treatment tank 1, and a rising frame 7 is welded to the four pillars 6, the wastewater treatment mechanism comprises a cylinder 8 installed on the rising frame 7, a bottom frame 9 connected to the bottom of the cylinder 8, a first motor 10 installed in the bottom frame 9, a transmission shaft 11 coaxially connected to the output shaft of the first motor 10, a stirring blade 12 installed on the transmission shaft 11 and a mixing dish 15 located in the inner cavity of the treatment tank 1, an inner oblique pipe 3 is fixedly connected to the bottom of the feeding pipe 2, a discharge pipe 4 is connected to the center of the bottom wall of the treatment tank 1, and a valve 5 is installed on the discharge pipe 4, so as to facilitate the control of the discharge of wastewater or flocculants;

[0023] The bottom of the inner oblique tube 3 is located just above the opening of the inner cavity of the mixing dish 15, so that the inner oblique tube 3 can add the papermaking wastewater to be treated and the flocculant into the mixing dish 15. The bottom frame 9 is in a mouth shape. The first motor 10 is vertically installed on the bottom wall of the inner space of the bottom frame 9, so that the structure of the first motor 10 remains stable. The stirring blade 12 extends into the inner cavity of the mixing dish 15 to mix and stir the wastewater and the flocculant. The stirring blade 12 has two blades symmetrically distributed on the transmission shaft 11, and the stirring blade 12 is integrally welded to the transmission shaft 11, so that the structure on both sides of the stirring blade 12 remains stable.
