[0002] How to protect our green mountains and clear waters while accelerating the process of industrialization is a common problem faced by the government and the whole society today. A large amount of wastewater is discharged during industrial production, and its composition is complex, and some of it is very toxic. If it is not effectively and centrally treated, it will cause serious environmental pollution to the soil, air, groundwater, etc., endangering human survival, causing serious harm to people's health, destroying the ecosystem, and hindering the sustainable development of the economy.

[0003] The cellulose production wastewater mainly comes from the cooling circulating water in the cellulose synthesis stage and the residual liquid when obtaining the solid cellulose semi-finished product. The pollution sources of cellulose production wastewater mainly include salts, soluble organic solvents, fine cellulose and other substances. Cellulose production wastewater has high salt content, high chemical oxygen demand COD (Chemical Oxygen Demand) and low BC ratio (BOD5 / CODCr); the use of wastewater treatment methods such as biochemical treatment and catalytic oxidation cannot achieve the treatment effect; membrane filtration, ion exchange and other delayed treatment methods have poor desalination effect and operability for brine containing a large amount of organic matter and high concentration. At present, the most common measure is to build a biochemical pool or a wastewater recovery pool. The biochemical pool is in a state of abandonment due to factors such as low treatment efficiency and low ambient temperature. The wastewater recovery pool is about to reach saturation under the continuous production state of the enterprise, which seriously affects the subsequent production progress. Therefore, how to effectively treat cellulose production wastewater is a manifestation of promoting the harmonious development of man and nature. It is still an important topic that needs to be studied at present to achieve recycling and reduce the cost of wastewater treatment while comprehensively and effectively treating cellulose production wastewater.

When each wastewater receiving trough 311 carries the electrode pin 332 and runs to the upright horizontal conveying section 211 of the wastewater receiving trough, the electrode pin 332 will slide and abut against the electrode strip 331 to realize the electrical heating of the heating body 32; when each wastewater receiving trough 311 carries the electrode pin 332 and leaves the upright horizontal conveying section 211 of the wastewater receiving trough, the electrode pin 332 is separated from the electrode strip 331, and the heating body 32 will be powered off and stop heating, thereby realizing the saving of electric energy and avoiding the overheating of the wastewater receiving trough 311 that is not filled with wastewater in the inverted horizontal conveying section 212 of the wastewater receiving trough, thereby causing production accidents.

[0079] In some embodiments, the electrode strip 331 includes an electrode strip 1 3311 and an electrode strip 2 3312 arranged on the frame 1, and the electrode pin 332 includes an electrode pin 1 3321 and an electrode pin 2 3322; the electrode strip 1 3311 and the electrode strip 2 3312 are parallel to each other and arranged at intervals; the electrode strip 1 3311 and the electrode strip 2 3312 are electrically connected to a power supply to form a power supply end; the electrode pin 1 3321 and the electrode pin 2 3322 are opposite to each other and arranged at intervals; the electrode pin 1 3321 and the electrode pin 2 3322 are electrically connected to the heating body 32 to form a power receiving end; when the wastewater receiving tank 311 runs to the upright horizontal conveying section 211 of the wastewater receiving tank, the electrode pin 1 3321 and the electrode pin 2 3322 slide and abut against the electrode strip 1 3311 and the electrode strip 2 3312 one by one, so that the heating body 32 is electrically connected to the power supply and powered for heating.

[0080] The provision of two electrode strips, electrode strip one 3311 and electrode strip two 3312, and the provision of two electrode pins, electrode pin one 3321 and electrode pin two 3322, can facilitate the power supply wiring of the circulating heating body 32, and all the heating bodies 32 are powered by electrode strip one 3311 and electrode strip two 3312.

[0081] Specifically, electrode strip one 3311 and electrode strip two 3312 are both copper electrode strips.

[0082] In some embodiments, the inner wall surface of the wastewater receiving tank 311 has a smooth transition in an arc shape along the conveying direction; the two ends of the plurality of wastewater receiving tanks 311 along the conveying direction are respectively formed as an arc-shaped outer surface 3111 and an arc-shaped inner surface 3112; the arc-shaped outer surface 3111 of any wastewater receiving tank 311 on the upright horizontal conveying section 211 of the wastewater receiving tank and the inverted horizontal conveying section 212 of the wastewater receiving tank and the arc-shaped inner surface 3112 of the adjacent wastewater receiving tank 311 are connected in an circumscribed circle manner.

[0083] For details, see Fig.11 , Fig.11 D, E, and F are all smooth arc surfaces; Fig.11 Here, G represents the arc corresponding to the arc-shaped inner surface 3112, and H represents the arc corresponding to the arc-shaped outer surface 3111; the G arc and the H arc are in a circumscribed circle relationship.

[0084] The trough chamber of the wastewater receiving trough 311 has a smooth transition in an arc along the conveying direction, so that the flexible scraper 41 can scrape the trough chamber of the wastewater receiving trough 311 smoothly and steadily without dead angles; the arc-shaped outer surface 3111 of any wastewater receiving trough 311 and the arc-shaped inner surface 3112 of the adjacent wastewater receiving trough 311 are connected in an circumscribed circle manner, the purpose of which is to enable the flexible scraper 41 to scrape smoothly at the connection between two adjacent wastewater receiving troughs 311 to avoid jamming and collision.

[0085] In some embodiments, the circulating conveying mechanism 2 is a plate chain conveying mechanism, which is composed of multiple chain plates 24 linked together. The spacing between adjacent chain plates on the horizontal section of the plate chain conveying mechanism is fixed. The specific structure of the plate chain conveying mechanism is the existing technology and will not be repeated here; the wastewater receiving tanks 311 are installed one by one on the chain plates 24 of the circulating conveying mechanism 2; the heating body 32 is installed between the wastewater receiving tank 311 and the chain plates 24.

[0086] Specifically, the wastewater receiving tank 311 is a strip-shaped tank body, and the wastewater receiving tank 311 is arranged along the length direction of the chain plate 24. The heating body 32 is a PTC heating plate, and the top end surface of the heating body 32 abuts against the bottom end surface of the wastewater receiving tank 311 to facilitate heat conduction.

[0087] The chain plate 24 provides an installation base for the wastewater receiving tank 311; the heating body 32 is installed between the wastewater receiving tank 311 and the chain plate 24. When the wastewater receiving tank 311 is upright, the heating body 32 is located below the wastewater receiving tank 311, and the heat generated by the heating body 32 is conducted to the wastewater receiving tank 311.

[0088] In some embodiments, the wastewater collection and drying mechanism 3 also includes an insulating positioning column 34 and an insulating pad 35; the insulating pad 35 is arranged between the heating body 32 and the chain plate 24 for insulation; the wastewater collection tank 311 is supported and fixed on the plate surface of the chain plate 24 by the insulating positioning column 34, and the wastewater collection tank 311 and the insulating positioning column 34 are fixed by countersunk screws. The countersunk screws are coated with high-temperature resistant sealing silicone before being fixed. The countersunk nails can ensure that the flexible scraper will not encounter resistance when scraping the semi-solid cellulose inside the wastewater collection tank, and the sealing silicone can ensure that the wastewater will not leak out through the countersunk screw holes.

[0089] Specifically, the thermal insulation pad 35 may be made of silicon dioxide nano-aerogel felt; thermal conductive silicone grease may be applied between the wastewater receiving tank 311 and the heating body 32 to improve thermal conductivity.

[0090] The heat insulation pad 35 serves to prevent the heat of the heating body 32 from being transferred to the chain plate 24 to avoid heat loss; the wastewater receiving tank 311 and the chain plate 24 are supported and isolated by the heat insulation positioning column 34, which blocks the wastewater receiving tank 311 from directly transferring heat to the chain plate 24, thereby avoiding heat loss and reducing the energy consumption of the device.

[0091] In some embodiments, the electrode assembly 33 further includes a pin mounting seat 333 , an electrode strip mounting beam 334 , and an insulating slot body 335 .

[0092] The ejector mounting seat 333 is fixed at one end of the chain plate 24 and corresponds to the side of the length direction of the wastewater receiving tank 311; the electrode ejector 3321 and the electrode ejector 3322 are arranged at intervals up and down, and one end of each is embedded in the preset mounting hole on the side wall of the ejector mounting seat 333 by transition fit and gluing, and the other end protrudes to the outside of the ejector mounting seat 333 as a sliding abutment end; the electrode ejector 3321 and the electrode ejector 3322 are both elastic electrode ejectors, and the effective stroke of their heads is 5mm, which can ensure that the electrode ejector and the electrode strip are effectively in contact when sliding relative to each other. The ejector mounting seat is made of PA46 high temperature resistant nylon material. The working voltage of the PTC heating plate is 48V, and the maximum current is 3A. The maximum current that can pass through the electrode ejector 3321 and the electrode ejector 3322 is 5A.

[0093] Specifically, two electrode pins 1 3321 and two electrode pins 2 3322 are arranged horizontally and spaced apart to avoid poor contact.

[0094] The electrode strip mounting crossbeam 334 is arranged parallel to the conveying direction of the upright horizontal conveying section 211 of the wastewater receiving trough and is located on one side above the circular conveyor belt 21. The insulating trough body 335 is fixed in parallel to the electrode strip mounting crossbeam 334. The side wall of the insulating trough body 335 has two parallel strip grooves arranged at intervals up and down. The electrode strip 1 3311 and the electrode strip 2 3312 are adapted and embedded in the two strip grooves one by one. The insulating trough body 335 is made of insulating PC material to keep the electrode strip 1 3311 and the electrode strip 2 3312 insulated and isolated.

[0095] Specifically, both ends of the electrode strip 1 3311 and the electrode strip 2 3312 have rounded sides to facilitate the corresponding electrode ejector pins to be smoothly inserted into the electrode slots.

[0096] In some embodiments, two heating bodies 32 are arranged at the bottom of each wastewater receiving tank 311 along the length direction of the wastewater receiving tank 311; there are two groups of electrode assemblies 33; the two heating bodies 32 are electrically connected to the two groups of electrode assemblies 33 in a one-to-one correspondence. The two groups of electrode assemblies 33 are arranged oppositely on both sides of the upright horizontal conveying section 211 of the wastewater receiving tank.

[0097] In some embodiments, an air drying and cooling mechanism 6 is also included. The air drying and cooling mechanism 6 is arranged corresponding to the wastewater receiving tank 311 at the tail end of the upright horizontal conveying section 211 of the wastewater receiving tank, and is fixed on the water vapor guide hood 51 to air dry and cool the solid or semi-solid cellulose in the wastewater receiving tank 311 passing through.

[0098] The air-drying and cooling mechanism 6 serves to further air-dry and cool the wastewater receiving tank 311 after drying, and can ensure that the wastewater receiving tank 311 is at a reasonable temperature while removing moisture, so as to avoid excessive temperature during the scraping process of the flexible scraper 41, thereby increasing wear or scalding.

[0099] Specifically, the air-drying and cooling mechanism 6 includes a heating fan. The heating fan can quickly discharge the hot air flow to the surface of the wastewater receiving tank 311, and can cool the wastewater receiving tank 311 and the solid or semi-solid cellulose. The purpose of using the heating fan is to avoid condensation of water vapor during the cooling process, and can further increase the evaporation rate of water on the surface of the solid or semi-solid cellulose.

[0100] In some embodiments, the flexible scraper 41 may be made of elastic silicone material to ensure that its top end can always abut against the wastewater receiving tank 311 and slide smoothly in and out of the tank chamber of the wastewater receiving tank 311 .

[0101] In some embodiments, the flexible scraper 41 can be made of a hard material, such as steel or wear-resistant nylon; the flexible scraper 41 is connected to the frame through an elastic telescopic member, and under the elastic force of the elastic telescopic member, the top of the flexible scraper 41 is always in contact with the inverted wastewater receiving tank 311, and can smoothly slide in and out of the tank chamber of the wastewater receiving tank 311.

[0102] Specifically, one end of the elastic telescopic member is fixed on the frame 1, and the other end is connected to the flexible scraper 41. The flexible scraper 41 is set vertically or slightly inclined. Under the elastic force of the elastic telescopic member, the flexible scraper 41 can be elastically extended along its own length direction to adapt to sliding in and out of the tank chamber of the wastewater receiving tank 311, and can always abut against the wastewater receiving tank 311 to maintain the scraping force.

[0103] In some embodiments, the flexible scraper 41 includes an adaptive telescopic scraper mechanism and an adaptive rotation mechanism;

[0104] The self-adaptive telescopic scraper mechanism includes a scraper assembly 411 and an elastic telescopic member 412; the scraper assembly 411 is connected to the elastic telescopic end of the elastic telescopic member 412, and its end is adapted to abut against the wastewater continuous collection tank assembly 31, and can be self-adaptively elastically telescoped under the pressure of the wastewater continuous collection tank assembly 31;

[0105] The adaptive rotation mechanism includes a torsion rotation frame 413; the fixed end of the elastic telescopic member 412 is fixed on the torsion rotation frame 413; under the pressure of the wastewater continuous receiving tank assembly 31, the torsion rotation frame 413 can make the scraper assembly 411 adaptively elastically twisted to change the scraping angle.

[0106] Specifically, the elastic telescopic member 412 can use an elastic telescopic rod (not shown in the figure) in the prior art; the torque rotating frame 413 includes a mounting beam 4131 and a torque output mechanism 4132; the mounting beam 4131 is horizontally arranged; the elastic telescopic member 412 is perpendicular to the mounting beam 4131 and is inclined to the horizontal direction, the fixed end of the elastic telescopic member 412 is fixed on the mounting beam 4131, the scraper assembly 411 is parallel to the elastic telescopic member 412 and the mounting beam 4131, and the scraper assembly 411 is fixed to the elastic telescopic end of the elastic telescopic member 412, and can be elastically lifted and retracted. The torque output mechanism uses a product in the prior art. There are two torque output mechanisms, and both are installed on the frame 1 through supporting columns; the two torque output mechanisms 4132 are symmetrically arranged at both ends of the mounting beam 4131, and their torque output ends are correspondingly connected to the two ends of the mounting beam 4131, which can drive the mounting beam 4131 to rotate around its own length direction, thereby driving the scraper assembly 411 to change the pressure of the rotating pressure against the surface to be scraped by the wastewater continuous collection tank assembly 31.

[0107] The adaptive telescopic scraper mechanism and the adaptive rotation mechanism enable the scraper assembly 411 to have two degrees of freedom, namely, telescopic and rotational, thereby improving the adaptability of the scraper assembly 411 to the curved surface to be scraped with a changing curvature.

[0108] In some embodiments, Fig.13 As shown, the flexible scraper 41 can be composed of 10 groups of single scrapers arranged in parallel, and each scraper is connected to the mounting crossbeam 4131 through an elastic telescopic member 412, which can ensure that the flexible scraper 41 is fully in contact with the interior of the wastewater receiving tank 311, thereby improving the scraping efficiency. At the same time, the flexible scraper 41 will continue to wear during use, and the array-shaped flexible scraper group can ensure the overall scraping efficiency when the single scraper is worn.

[0109] In some embodiments, the collecting assembly 42 includes an inclined guide plate 421 and a collecting trough body 422; the collecting trough body 422 is located below the flexible scraper 41, and the inclined guide plate 421 is arranged between the flexible scraper 41 and the collecting trough body 422 to guide the solid or semi-solid cellulose peeled off in the wastewater receiving tank 311 to the collecting trough body 422.

[0110] Specifically, the top of the inclined guide plate 421 corresponds to the bottom of the flexible scraper 41, and the bottom of the inclined guide plate 421 corresponds to the top of the collecting tank 422; the peeled solid or semi-solid cellulose can slide down along the inclined guide plate 421. The flexible scraper 41 is located below the wastewater collection tank 311, and the collecting tank 422 is located below the flexible scraper 41. The peeled solid or semi-solid cellulose is collected by its own gravity, without the need for power transmission, with a simple structure, energy saving and environmental protection. The collecting tank 422 can be transported by workers or machinery to the drying area for natural drying. The moisture in the semi-solid cellulose will evaporate in a short time, and the remaining solid cellulose can be recycled.

[0111] It should be noted that the heating time and heating power of the heating body can be adjusted as needed to control the moisture content of the cellulose after drying. The so-called semi-solid cellulose refers to cellulose that still contains a certain amount of moisture; drying to semi-solid cellulose can ensure that the semi-solid cellulose adheres to the collection tank body 422 so as to be easily transported to the inverted horizontal conveying section 212 of the wastewater collection tank, and can also facilitate the smooth scraping of the flexible scraper, and can further save electricity.

[0112] Specifically, the inclined guide plate 421 and the collecting tank body 422 are both made of bent sheet metal, and the manufacturing cost is low.
