Description

TECHNICAL FIELD

[0001] The utility model relates to fish slice processing technical field, concretely relates to a fish washing wastewater treatment device. BACKGROUND

[0002] In the fish slice processing process, when the fish slice is cut off from the fish, the worker will directly put the fish slice on the conveying belt and send it to the rear packing. Occasionally, due to cutting or conveying belt reasons, the fish slice conveyed to the packing place by the conveying belt will have a small amount of fish meat scraps, fish skin or impurities attached. Before packing the fish slice, clean water (tap water) is used to flush the fish slice to remove the fish meat scraps, fish skin or impurities attached to the fish slice, so as to improve the appearance and quality of the fish slice.

[0003] Since it is in the later stage of processing, the fish slice itself is relatively pure, and the wastewater after flushing the fish slice mainly contains fish meat, which is insoluble in water, and the pollution to water is limited in a short time. Therefore, it is not only feasible to treat the wastewater generated after flushing the fish meat and then reuse it to flush the fish meat, but also can save a lot of water resources.

[0004] The existing fish washing wastewater treatment equipment mainly relies on filter screen to filter out meat and skin substances in fish washing wastewater. However, the organic substances intercepted by the filter screen can easily rot and breed bacteria after a period of time, so the filter screen needs to be frequently flushed and replaced, otherwise the circulating wastewater will carry bacteria after flushing the intercepted substances again. This treatment method is prone to omissions and is also relatively wasteful of manpower.

[0005] Therefore, a fish washing wastewater treatment device for fish slice cleaning water recycling is designed, which can automatically update the filter contact surface, avoid the fish washing water in the cycle from flushing the long-stored intercepted substances during the recycling process, avoid the bacteria of rotten organic substances entering the circulating water, and improve the safety of fish washing wastewater recycling.

[0009] When using the above scheme, the fish washing wastewater is uniformly pumped to the backwater tank, guided to the drain pipe through the drain trap, and then discharged through the drain pipe. The discharged fish washing wastewater flows downward, impinges on the filter cotton passing through the upper of the water storage tank, and then flows into the water storage tank below. The fish meat scraps, fish skin, impurities and the like in the wastewater are intercepted by the filter cotton. During the operation of the entire device, the drive mechanism drives the second rotation axis to rotate continuously to collect the filter cotton, and the filter surface with intercepted objects is continuously extracted and wound onto the second rotation axis, so as to continuously update the filter contact surface, avoid the fish washing water in the circulation from having the opportunity to flush the long-time standing intercepted objects during the circulation process, avoid the bacteria of rotten organic matter from entering the circulating water, and improve the safety of the reuse of the fish washing wastewater.

[0010] The resistance mechanism provides rotation resistance for the first rotation axis. Under the rotation resistance and extraction of the second rotation axis, the filter cotton can maintain a certain degree of bounce, so that it can normally pass through the upper of the water storage tank. The two first guide cylinders and the two second guide cylinders also help to maintain the combing state of the filter cotton, preventing the filter cotton from being twisted.

[0011] Further technical solutions are, still including the sixth support set in the water storage tank, the sixth support is horizontally provided with a horizontal rod pointing to one side of the water storage tank, the horizontal rod is fixedly provided with a vertical rod at the bottom of the end, the vertical rod is rotatably installed with a roller at the bottom, the center axis of the roller is parallel to the center axis of the first rotating shaft, the lowest part of the roller is lower than the lowest part of the lower first guide roller among the two first guide rollers, and is lower than the lowest part of the lower second guide roller among the two second guide rollers, the bottom of the roller abuts against the upper end surface of the filter cotton passing above the water storage tank to press the filter cotton to form a valley-shaped part downward, and the pipe opening of the drain pipe points to the valley-shaped part.

[0012] When using the above scheme, the upper end surface of the filter cotton is pressed to form a valley-shaped part by the roller, which facilitates the filter cotton to better receive the wastewater discharged from the drain pipe, and the valley-shaped filter cotton can also provide a larger filtering area to improve the filtering rate.

[0013] Further technical solutions are, the resistance mechanism includes a gear fixedly sleeved on the first rotating shaft, the center axis of the gear coincides with the center axis of the first rotating shaft, the resistance mechanism further includes a spring needle fixedly arranged on the first support, and the needle of the spring needle abuts against the teeth of the gear.

[0014] When using the above scheme, when the filter cotton is extracted by the second rotating shaft, the filter cotton pulls the first rotating shaft to rotate, the first rotating shaft drives the gear to rotate, the teeth on the gear push the needle of the spring needle, and the gear can rotate after the needle of the spring needle is retracted. The number of booster spring needles or the selection of spring needles with different elastic forces can change the rotating resistance of the gear.

[0015] Further technical solutions are, the driving mechanism includes a motor fixedly arranged on the second support, the output shaft of the motor is drivingly connected with a speed reducer, and the speed reducer is drivingly connected with the second rotating shaft to drive the second rotating shaft to rotate.

[0016] When using the above scheme, the motor drives the speed reducer, the speed reducer drives the second rotating shaft, and the rotating speed of the motor can effectively adjust the extraction speed of the filter cotton.

[0017] Further technical solutions are, a plurality of threaded holes are further formed in the side wall of the second rotating shaft, and screws are detachably screwed in the threaded holes.

[0018] When using the above scheme, by arranging the threaded holes and the screws, the filter cotton can be quickly replaced and wound on the second rotating shaft. After the screws pass through the filter cotton and are screwed in the threaded holes, the filter cotton can be quickly fixed.

[0019] Further technical solutions are, the water storage tank is further provided with a water outlet pipe at the bottom, a water pump is further arranged outside the water storage tank, and the water inlet of the water pump is communicated with the water storage tank through the water outlet pipe.

[0020] When the above scheme is used, the filtered water in the water storage tank can be pumped back to the fish washing position through the water outlet pipe and the water pump.

[0021] A further technical solution is that the interval distance of the two first guide rollers is less than the thickness of the filter cotton.

[0022] When the above scheme is used, the filter cotton can be prevented from shaking up and down.

[0023] A further technical solution is that the interval distance of the two second guide rollers is less than the thickness of the filter cotton.

[0024] When the above scheme is used, the filter cotton can be prevented from shaking up and down, and part of the water on the filter cotton can be removed, facilitating collection.

[0025] A further technical solution is that a fifth support is arranged beside the water storage tank, and the water return tank is fixed on the fifth support.

[0026] A further technical solution is that the filter cotton is cashmere cotton.

[0027] When the above scheme is used, the cashmere cotton has the advantages of high interception, high water permeability, high toughness, low price, and is more suitable for use in the device.

[0028] The beneficial effects of the device are as follows:

[0029] 1. Efficient filtration: the filter cotton effectively intercepts fish meat scraps, fish skin, impurities and the like in the fish washing wastewater, ensuring clean water quality.

[0030] 2. Continuous update of the filter surface: the driving mechanism continuously collects the filter cotton, updates the filter contact surface, prevents the intercepted objects from being washed away for a long time, reduces bacterial growth, and improves the safety of wastewater reuse.

[0031] 3. Stable operation: the resistance mechanism provides rotational resistance for the first rotating shaft, cooperates with the extraction of the second rotating shaft, maintains the bouncing degree of the filter cotton, and ensures that it normally passes above the water storage tank.

[0032] 4. Prevention of distortion: the first and second guide rollers help maintain the combing state of the filter cotton, prevent it from being distorted, and affect the filtering effect.

[0033] 5. Increase the filtering area: the rollers are arranged to compress the filter cotton to form a valley-shaped part, which not only facilitates the acceptance of wastewater, but also provides a larger filtering area and improves the filtering rate. BRIEF DESCRIPTION OF DRAWINGS
