[0002] Zero discharge of papermaking wastewater is of great significance to environmental protection. The current treatment processes for achieving zero discharge of wastewater include evaporation process, that is, through evaporation of wastewater, the polluting dissolved substances in the wastewater are precipitated and crystallized, and solid impurities are retained, and then the clean water is evaporated to achieve zero discharge of polluting dissolved substances and impurities.

[0003] Considering that evaporation requires the use of thermal energy to heat wastewater, energy conservation can be achieved by combining existing evaporation ponds with photovoltaic devices. However, during the zero-discharge treatment process of wastewater evaporated in evaporation ponds, it was found that the dissolved matter in the wastewater precipitated after evaporation and scale would form at the bottom of the pond. The scaling impurities accumulated at the bottom of the pond need to be dealt with in a timely manner, and the existing evaporation ponds are inconvenient to clean. In view of this, we propose a zero-discharge treatment device for toilet paper production wastewater. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-6 The present invention describes the above technical solution in detail through the following embodiments:

[0035] A zero-discharge treatment device for production wastewater is applicable to the field of toilet paper production containing solid waste and scale, so as to treat scale formed on the bottom of the pool after the dissolved matter evaporates from the toilet paper production wastewater. The device comprises an evaporation pool 1 for carrying the production wastewater to be treated, and further comprises:

[0036] The wastewater evaporation part includes a heating unit 2 installed at the bottom of the evaporation pool 1 to provide an evaporation heat source, and a pad 3 installed above the heating unit 2. Figure 3-Figure 5 As shown in the structure, the heating unit 2 of this embodiment includes an inverted T-shaped bin 21 provided with a heating liquid chamber 211, and a mounting groove 212 for inserting an electric heating rod 22 is provided on the inverted T-shaped bin 21. Liquid is injected into the heating liquid chamber 211 and heated by the electric heating rod 22 to obtain a heat source for the wastewater in the heat-conducting evaporation pool 1, causing the wastewater to evaporate by heat.

[0037] In this embodiment, the backing plate 3 is provided with a slot 31 for being inserted into the inverted T-shaped bin 21 , and the backing plate 3 is provided with protrusions 32 at both ends of the slot 31 , and the protrusions 32 are provided with mounting holes 321 .

[0038] In order to realize the up and down movement of the pad 3, Figure 1 and Figure 3 As shown, in this embodiment, two C-shaped gusset plates 4 are installed between the evaporation pool 1 and the inverted T-shaped bin 21; a vertical rod 5 for inserting into the mounting hole 321 on the pad 3 is installed on one side of the C-shaped gusset plate 4, and a vertical threaded rod 6 for threadedly connecting the pad 3 is rotatably installed on the other side of the C-shaped gusset plate 4, and the vertical threaded rod 6 is coaxially connected to the first motor 7; that is, based on the screw principle, the first motor 7 drives the vertical threaded rod 6 to rotate, so that the threaded pad 3 is lifted and lowered along the direction of the vertical rod 5; and the reason why the protrusion 32 is provided in this embodiment is that after the protrusion 32 is pressed against the C-shaped gusset plate 4, the upper surface of the pad 3 is located at the highest pool edge of the evaporation pool 1.

[0039] refer to Figure 1 、 Figure 6 In the structure shown, the scraper assembly 8 includes a material receiving bin 81 and an L-shaped side support plate 82 installed at the edges of both sides of the evaporation pool 1, and a scraper 83 for reciprocating along the horizontal plane is installed between the material receiving bin 81 and the L-shaped side support plate 82.

[0040] Specifically, a convex baffle 811 is provided on the material receiving bin 81, and two groups of sliding rods 84 symmetrically arranged about the inverted T-shaped bin 21 and a threaded horizontal threaded rod 85 are fixedly installed between the convex baffle 811 and the L-shaped side support plate 82. A second motor 86 is coaxially connected to the horizontal threaded rod 85, and the scraper 83 is slidably installed on the sliding rod 84 and threadedly connected to the horizontal threaded rod 85; that is, based on the screw principle, the two scrapers 83 can be moved back and forth along the sliding rod 84, so when it is necessary to clean the scaling impurities on the surface of the pad 3, the pad 3 can be raised to the highest point. At this time, the scraper 83 moves to just scrape off the scaling impurities, thereby reducing the impact of scaling on subsequent treatments. Its operation is simple and reliable.
