Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, in particular to a wastewater treatment device for food processing. Background Art

[0002] The food industry uses a wide range of raw materials and produces a wide variety of products. The amount and quality of wastewater discharged vary greatly. The main pollutants in the wastewater include solid matter floating in the wastewater, such as vegetable leaves, fruit peels, minced meat, poultry feathers, etc., substances suspended in the wastewater include oil, protein, starch, colloids, etc., acids, alkalis, salts, sugars, etc. dissolved in the wastewater, mud and sand and other organic matter carried by the raw materials, pathogenic bacteria and viruses, etc. The characteristics of food industry wastewater are high content of organic matter and suspended matter, easy to corrupt, and generally not highly toxic. Its main harm is eutrophication of water bodies, which causes the death of aquatic animals and fish, prompts organic matter deposited on the bottom of the water to produce odor, deteriorates water quality, and pollutes the environment.

[0003] Publication No. CN218232017U discloses a high-salinity wastewater treatment device for food processing. When caustic soda is added to a high-salinity wastewater tank, agglomerated caustic soda can be separated from unagglomerated caustic soda. The unagglomerated caustic soda can first enter the high-salinity wastewater tank to react with the high-salinity wastewater, while the agglomerated caustic soda can be uniformly dispersed and crushed before entering the high-salinity wastewater tank. The agglomerated caustic soda is dispersed and crushed effectively, thereby increasing the reaction rate between the high-salinity wastewater and the caustic soda, thereby improving the treatment efficiency of the high-salinity wastewater. However, this patent still has the following problems in actual use:

[0004] Although the high-salinity wastewater treatment device for food processing can treat high-salinity wastewater, the main pollutants in the food processing wastewater include solid matter floating in the wastewater, such as vegetable leaves, fruit peels, minced meat, poultry feathers, etc., and the substances suspended in the wastewater include grease, protein, starch, colloids, etc. During the wastewater treatment, the grease in the wastewater cannot be treated, resulting in poor wastewater treatment effect. At the same time, the existing technology uses adsorption materials such as activated carbon and resin to adsorb grease and organic matter to the surface of the material, but it requires a large amount of activated carbon, resin and other materials, which is not conducive to cost saving.

[0005] Therefore, a wastewater treatment device for food processing is proposed to solve the above problems. Summary of the Invention

[0043] Working principle: Before using this wastewater treatment device for food processing, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 11 As shown, first, the wastewater is passed into the filter box 210 inside the filter bracket 201, and the aeration motor 212 drives the third sprocket transmission assembly 213 and the aeration roller 214 to rotate. Gas is injected into the wastewater through the aeration device 217. By injecting gas into the wastewater, grease and suspended particles are attached to the bubbles. As the bubbles rise to the water surface, scum is formed. The translation motor 104 drives the first sprocket transmission assembly 105 and the translation thread rod 106 to rotate, so that the translation thread sleeve 107 drives the translation bracket 201 to rotate.

[0044] Secondly, when the cleaning roller 127 and the cleaning brush 128 move to the surface of the wastewater, the cleaning motor 125 is started to drive the mounting bracket 126 to rotate. By utilizing the characteristics of the engagement connection between the mounting bracket 126 and the cleaning roller 127, the rotation of the cleaning roller 127 and the cleaning brush 128 can be realized, and the impurities floating on the surface of the wastewater can be cleaned into the collection buckets 132 on both sides. The first filter screen 133 inside the collection bucket 132 can filter the impurities. At the same time, before the impurities on the surface of the wastewater are cleaned, the conveying motor 135 is started to drive the second sprocket transmission assembly 136 and the conveying roller 137 to rotate. By utilizing the characteristics of the transmission connection between the conveying roller 137 and the oil suction conveyor belt 138, the rotation of the oil suction conveyor belt 138 can be realized. At the same time, through the meshing gear group 1 39 can realize the rotation of the refrigeration roller 140, and cool the surface of the oil absorption conveyor belt 138 through the refrigeration roller 140, so that the grease floating on the surface of the wastewater solidifies and adheres to the oil absorption conveyor belt 138 after cooling, and the grease on the surface of the oil absorption conveyor belt 138 is cleaned by the cleaning scraper 141, and the grease is absorbed by the oil absorber 142, thereby improving the efficiency of grease cleaning, and the water in the cleaning water tank 117 is pumped into the interior of the heater 120 through the water pump inside the water outlet bracket 119 to be heated, and sprayed out through the cleaning nozzle 121, which can perform high-temperature flushing on the cleaning roller 127 and the cleaning brush 128, facilitate the cleaning of the cleaning roller 127 and the cleaning brush 128, and improve the service life of the cleaning roller 127 and the cleaning brush 128.

[0045] Finally, the cleaning rake 205 on the top side of the guide block 204 is used to clean the impurities and entangled hair or strips on the surface of the cleaning brush 128. At the same time, the cleaned impurities fall into the guide trough 203 for collection, and the cleaning cover 207 is opened by the cleaning handle 208 to clean the guide trough 203. By setting the guide block 204, it can play a guiding role when the oil suction bracket 134 moves to the top of the guide block 204, so that the support cover 131 rotates under the action of the torsion spring hinge 130, so that the collection bucket 132 is tilted, and the impurities on the surface of the collection bucket 132 are cleaned. The grease and impurities are cleaned with high-temperature cleaning water, which facilitates the cleaning of the collection bucket 132. The wastewater is filtered through the second filter screen 211 inside the filter box 210, and the enlarged impurities and particulate matter in the wastewater can be filtered and processed. The feature of placing the limit plate 209 and fittingly connecting with the guide trough 203 can be used to remove the filter box 210, thereby cleaning the filter box 210.
