Description

Technical Field

[0001] The utility model relates to a silk-boiling water treatment technology, in particular to a silk-boiling water reflux treatment system. Background Art

[0002] Boiling silk is an essential process in the processing of silkworm cocoons. It involves soaking the silkworm cocoons in water to allow the water to penetrate into the cocoons, then adding chemical additives such as alkaline substances, peroxides or surfactants to heat and boil to kill the silkworm pupae in the cocoons, and swelling and dissolving the sericin around the cocoons to make the silk suitable for subsequent processing. Since the wastewater after silk boiling contains sericin protein, pupa protein and other fatty acid organic substances and chemical additive residues, direct discharge will cause water pollution. Since silk boiling water does not contain solid impurities such as mud and sand, the current silk boiling water treatment process is basically as follows: the silk boiling water is filtered and flows into the water collection pool, and the water collection pool is ventilated and dissolved in air for oxidation, and then the water is sent to a biological treatment tower with microbial strains for treatment to decompose or degrade organic matter, remove soluble organic matter and inorganic camps in the wastewater, flocculate and precipitate, and degrade colloidal solids, and then filtered to obtain the treated silk boiling water, which can be discharged or used for other purposes. However, the above treatment has the following problems: first, the boiled silk water contains a large amount of silk fibers or silk clusters shed from silk cocoons, which are intercepted by the filtering equipment during filtration, and the boiled silk water contains colloidal solids. The colloidal solids and the intercepted silk fibers or silk clusters will form a gel-like silk thread layer that blocks the filtering equipment; second, the treatment process mainly treats the boiled silk water by microorganisms in a biological treatment tower, and the treatment area is small and the time is short, which may lead to untimely or incomplete treatment of the boiled silk water, resulting in the boiled silk water failing to meet the treatment requirements after treatment. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a silk boiling water reflux treatment system which can timely clean the fibers or silk balls in the silk boiling water and timely and thoroughly treat the silk boiling water.

[0005] As a preferred technical solution, the cleaning device includes a cleaning rack, the lower end of which is inserted into a cleaning well connected to the silk boiling water discharge pipeline, a chain belt is installed between the upper and lower ends of the cleaning rack via a rotating shaft, a power device for driving the chain belt is arranged on the top of the cleaning rack, and the chain belt is provided with hook teeth protruding from the outer surface of the chain belt.

[0006] As a preferred technical solution, rubber baffles are respectively installed between the two sides of the cleaning rack and the inner wall of the cleaning well.

[0007] As a preferred technical solution, a cleaning roller is rotatably arranged on the back side of the upper part of the cleaning frame near the chain belt, and a plurality of rubber cleaning plates are circumferentially distributed on the outer side of the roller body of the cleaning roller. The length of each cleaning plate extends along the axial direction of the roller body, and cleaning teeth are arranged on the outer edge of each cleaning plate. The cleaning roller is transmission-connected to a power device; a guide slide is arranged on the cleaning frame at the lower side of the cleaning roller.

[0008] As a preferred technical solution, the post-filtration device includes a sand filter tower whose water inlet is connected to a biochemical treatment tower, and the post-biochemical treatment device is a biological activated carbon filter tower whose water inlet is connected to a sand filter tower water outlet, and the biological activated carbon filter tower water outlet is connected to a water storage tower.

[0009] By adopting the above-mentioned technical scheme, the silk-boiling water reflux treatment system can timely remove waste silk balls or silk fibers in the silk-boiling water through the cleaning device before filtering, thereby avoiding the phenomenon that the colloidal solids in the silk-boiling water interact with the silk fibers or silk balls to form a gel-like silk thread layer to block the filtering equipment. The post-biochemical treatment device is arranged between the post-filter device and the water storage tower to increase the treatment process and treatment time of the silk-boiling water. Moreover, through the biochemical water reflux pipeline between the biochemical treatment tower and the water collection pool, the silk-boiling water containing part of microorganisms after treatment in the biochemical treatment tower is refluxed into the water collection pool, so that the water collection pool also contains a small amount of microorganisms, and the silk-boiling water in the water collection pool is also treated by microorganisms. In this way, the utility model greatly increases the treatment area and process of the silk-boiling water by microorganisms, prolongs the treatment time, and treats the silk-boiling water in a timely and thorough manner, so that the treated silk-boiling water meets the treatment requirements.

[0017] like Figure 1 and 2As shown, the cleaning device 1 comprises a cleaning frame 11, the lower end of which is inserted into a cleaning well 22 connected to the discharge pipeline of the boiled silk water, a chain belt 13 is installed between the upper and lower ends of the cleaning frame 11 through a rotating shaft 12, a power device 14 for driving the chain belt 13 is arranged on the top of the cleaning frame 11, and a hook tooth 15 protruding from the outer surface of the chain belt 13 is arranged on the chain belt 13. The cleaning well 22 is connected to the filter well 9 of the filter device 2 through a water supply pipeline, and the power device 14 can be connected to a speed change mechanism by a motor, and the speed change mechanism is connected to the rotating shaft 12 through a chain drive to drive the chain belt 13 to circulate and rotate on the cleaning frame 11. When working, driven by the power device 14, the chain belt 13 circulates and rotates on the cleaning frame 11 with the hook tooth 15, and the boiled silk water is transported to the cleaning well 22 through the discharge pipeline, and the water flows through the gaps on the chain belt 13, and the silk fibers or silk balls in the boiled silk water are grabbed by the hook tooth 15 and taken out of the cleaning well 22 and removed. Rubber baffles 16 are respectively installed between the two sides of the cleaning frame 11 and the inner wall of the cleaning well 22 to prevent silk fibers or silk balls from flowing between the two sides of the cleaning frame 11 and the inner wall of the cleaning well 22, thereby improving the cleaning effect; and the rubber baffles 16 can be tilted to allow the silk fibers or silk balls to flow toward the chain belt 13 under the impact of the water flow, thereby facilitating cleaning. The cleaning device 1 can also use a tilted and rotating screen cage, with openings at both ends of the screen cage, and the silk-boiling water is fed into the filter through the opening at the upper end of the screen cage, and the silk fibers or silk balls in the silk-boiling water are intercepted by the tilted rotating screen cage and then fall out of the opening at the lower end of the right screen cage for cleaning.

[0018] like Figure 4 As shown, the hook teeth 15 can be directly set on the chain plate of the chain belt 13, or can be set separately on the plate body 17.

The hook teeth 15 hook the silk fibers or silk balls and run upward out of the cleaning well 22 under the drive of the chain belt 13, then move to the upper part of the cleaning frame 11 and turn to run downward from the back side. At this time, the power device 14 drives the cleaning roller 18 to rotate, and the rubber cleaning plate 19 on the cleaning roller 18 cleans the silk fibers or silk balls from the hook teeth 15. The chain belt 13 drives the hook teeth 15 to continue to move downward to the lower end of the cleaning frame 11 and turn to run upward from the front side to continue to grab the silk fibers or silk balls. The silk fibers or silk balls removed from the hook teeth 15 by the cleaning roller 18 fall on the guide slide plate 21 and then slide into the collection box or basket for transportation. The cleaning teeth 20 arranged on the outer edge of the cleaning plate can make the outer edge of the cleaning plate contact with the chain belt 13 to improve the cleaning effect. It is preferred that the hook teeth 15 pass through the gaps between the cleaning teeth 20 when the cleaning roller 18 rotates.

The sand filter tower filters the flocculation precipitation and the like generated during the treatment process of the biochemical treatment tower 4, and the filtered silk-boiling water is sent to the biological activated carbon filter tower. The biological activated carbon in the biological activated carbon filter tower can give full play to the adsorption of activated carbon and the degradation of microorganisms, so that pollutants are adsorbed and degraded at the same time, and the silk-boiling water is further subjected to microbial treatment and filtration at the same time, which increases the microbial treatment process of the silk-boiling water, prolongs the treatment time, and treats the silk-boiling water in a timely and thorough manner, so that the treated silk-boiling water meets the treatment requirements.

After being treated by the biochemical treatment tower 4, most of the water is sent to a sand filter tower for filtration and then to a biologically activated carbon filter tower for adsorption and microbial treatment. Then the treated water is sent to a water storage tower 7.
