Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to a sewage treatment device for ecological condiment production. Background Art

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging into a certain water body or reusing it. Sewage treatment is widely applied in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering. Classified by the source of sewage, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage, and medical sewage, etc. Domestic sewage is the sewage generated in daily life, which is a complex mixture of various forms of inorganic and organic substances, including large and small solid particles floating and suspended, colloidal and gel-like diffusates, and pure solutions. Classified by the nature of water pollution, water pollution is of two types, one is natural pollution; the other is man-made pollution. Currently, the man-made pollution is more harmful to water bodies. Water pollution can be mainly divided into three categories: chemical pollution, physical pollution, and biological pollution according to different pollution impurities.

[0003] Condiments mainly refer to herbs and spices. Herbs are the leaves of various plants, which can be fresh, dried, or ground. Spices are the seeds, flower buds, fruits, flowers, barks, and roots of plants. The taste of spices is much stronger than that of herbs. In some cases, a plant can be used for both herb production and spice production. Some condiments are composed of a mixture of multiple spices (such as paprika powder), or a mixture of multiple herbs (such as spice bags).

[0004] The sewage generated during the production of ecological condiments (such as fermented soy sauce, natural sauce, etc.) has the following characteristics: complex composition: containing high-concentration organic substances (such as sugars, proteins), animal and vegetable oils and fats, salts, and additives (preservatives, pigments); large water quality fluctuations: the production cycle causes significant changes in the sewage volume and pollutant concentration, and the pH value fluctuates frequently (pH 4 - 10) due to fermentation or cleaning steps. Currently, the application of sewage treatment equipment in the field of ecological condiments has the following problems: low pretreatment efficiency, traditional grilles rely on mechanical cleaning, are easily blocked by large particulate suspensions, and require frequent shutdown for maintenance. The single air flotation method has a low removal rate of emulsified oil (particle size < 10μm) (< 60%), the chemical demulsifier has a high cost and residual toxicity, and the sewage treatment efficiency is low. Summary of the Invention

[0005] The present invention provides a sewage treatment device for ecological condiment production, which solves the problems in the prior art that traditional grilles rely on mechanical cleaning, are easily blocked by large particulate suspensions, require frequent shutdown for maintenance, the single air flotation method has a low removal rate of emulsified oil, the chemical demulsifier has a high cost and residual toxicity, and the sewage treatment efficiency is low.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

A transmission assembly is arranged inside the installation cylinder. The transmission assembly includes a transmission shaft, a transmission impeller connected to the outer wall of the upper part of the transmission shaft by a pin shaft, a mixing impeller connected to the outer wall of the middle part of the transmission shaft by a pin shaft, and a spiral blade welded on the outer wall of the lower part of the transmission shaft. A transmission motor is arranged above the installation cylinder. A flocculation conveying pipe is arranged on one side of the installation cylinder, and one end of the flocculation conveying pipe penetrates and is fixed on the inner wall of the upper part of the filter pipe. A treatment mechanism is arranged on one side of the installation cylinder. The treatment mechanism includes a flotation cylinder, a connecting cylinder welded on the outer wall of the bottom of the flotation cylinder, a conical guide cover bolted to the inner wall of the upper part of the connecting cylinder, and a filter cylinder with a titanium-based coating electrode sprayed on the inner wall of the bottom. A flotation oil removal assembly is arranged inside the flotation cylinder. The flotation oil removal assembly includes an air delivery pipe, a microbubble generator screwed on the outer wall of the lower part of the air delivery pipe, a plurality of swirl vanes welded on the outer wall of the microbubble generator, and a swirl motor. A membrane separation assembly is arranged inside the filter cylinder. The membrane separation assembly includes a filter element composed of a ceramic ultrafiltration membrane and an anti-pollution reverse osmosis membrane, and a filter ring embedded on the outer wall of the filter element.

[0008] Preferably, a support ring is bolted to the inner wall of the lower part of the installation cylinder, and a plurality of drain ports are opened on the outer wall of the support ring. The installation cover is welded to the top outer wall of the support ring, the pre-separation cylinder abuts against the top outer wall of the support ring, a cylinder cover is flange-connected to the top outer wall of the installation cover, and a liquid inlet pipe is fixed on the outer wall of the cylinder cover.

[0009] Through the above solution, the sewage generated during condiment production is conveyed into the pre-separation cylinder through the liquid inlet pipe. The ultrasonic transducer converts the energy of ultrasonic waves into vibrations, breaking the large-particle suspended solids in the sewage.

[0010] Preferably, a drain pipe is fixed on the inner wall of the bottom of the regulating cylinder. The inner side of the spiral guide plate abuts against the outer wall of the filter pipe, and a polytetrafluoroethylene coating is sprayed on the outer wall of the spiral guide plate. A plurality of pH sensors are installed on the inner wall of the regulating cylinder.

[0011] Through the above solution, the space formed by the adjusting cylinder, the spiral guide plate and the filter tube is used to guide the sewage. The sewage descends spirally along the spiral guide plate, and at the same time, the sewage passes through the filter tube. Meanwhile, multiple pH sensors detect the pH value of the sewage, and cooperate with multiple pH adjusting tubes to adjust the pH value of the sewage in real time.

[0012] Preferably, the transmission shaft is composed of two rotating shafts. A clamping groove with a regular hexagon structure is opened at the bottom of one rotating shaft, and a boss with a regular hexagon structure is provided at the top of the other rotating shaft. The boss is clamped in the clamping groove. The upper part of the transmission shaft penetrates and is connected to the outer wall of the top of the cylinder cover through a bearing, and the middle part of the transmission shaft penetrates and is connected to the outer wall of the bottom of the pre-separation cylinder through a bearing. The spiral blade is sleeved in the filter tube. A fixing block is fixedly arranged on the inner wall of the lower part of the filter tube, and the transmission shaft penetrates and is connected to the outer wall of the fixing block through a bearing.

[0013] Through the above solution, the chitosan-modified bentonite composite flocculant is put into the upper space of the filter tube through the flocculation conveying pipe. The precipitate generated during flocculation falls on the upper part of the spiral blade. When the sewage enters the pre-separation cylinder, it impacts the transmission impeller. The transmission impeller drives the transmission shaft, the mixing impeller and the spiral blade to rotate. The rotation of the spiral blade keeps the precipitate in the upper part of the filter tube.

The driving synchronous belt and the driven synchronous belt form a transmission cooperation through the synchronous belt.

[0015] Through the above solution, the output shaft of the driving motor drives the transmission shaft and the spiral blade to reverse. The spiral blade conveys the precipitate to the lower part of the filter tube, and at the same time, clear water is input through the liquid inlet pipe, and the clear water flushes the precipitate.

[0016] Preferably, a top cover is connected to the outer wall of the top of the air flotation cylinder through a flange, and an oil suction pipe for floating oil is fixedly arranged on the outer wall of the top cover. A plurality of through holes are opened on the outer wall of the lower part of the guide cover. The filter cylinder is connected to the outer wall of the bottom of the connecting cylinder through a flange. A limiting ring is welded on the inner wall of the bottom of the filter cylinder, and a drain pipe is fixedly arranged on the inner wall of the bottom of the filter cylinder.

[0017] Preferably, the upper part of the air delivery pipe penetrates through and is connected to the outer wall of the top cover through a bearing. A plurality of exhaust holes are formed in the outer wall of the microbubble generator, and one-way valves are embedded in the plurality of exhaust holes. A fixing frame is welded on the outer wall of the top of the top cover, and the swirl motor is connected to the top outer wall of the fixing frame through bolts. The middle of the output shaft of the swirl motor is connected with a driving pulley through a pin shaft, and the outer wall of the upper part of the air delivery pipe is connected with a driven pulley through a pin shaft. The driven pulley is in transmission cooperation with the driving pulley through a belt.

[0018] Through the above solution, the air delivery pipe is connected to the air compressor through a rotary joint. Compressed air enters the microbubble generator along the air delivery pipe. The rotation of the output shaft of the swirl motor drives the air delivery pipe and the microbubble generator to rotate. The microbubble generator generates a large number of tiny bubbles. The centrifugal force generated by the rotation of the swirl vane makes the sewage-containing form a swirl, enhancing the floating rate of oil droplets. The titanium-based coating electrode is energized with low-voltage direct current to generate hydroxyl radicals to decompose emulsified oil. Subsequently, the floating oil on the upper layer is pumped out through the floating oil suction pipe.

[0019] Preferably, a three-way discharge valve is screwed to the lower part of the liquid discharge pipe, and a delivery pipe is screwed to the inner wall of one end of the three-way discharge valve. One end of the delivery pipe penetrates through and is fixed on the inner wall of the upper part of the air flotation cylinder, and an infusion pump is installed on the outer wall of one end of the delivery pipe by face clamping.

[0020] Preferably, the lower part of the filter element is sleeved on the inner wall of the limit ring, and the bottom of the filter ring abuts against the top outer wall of the limit ring.

[0021] Through the above solution, the oil-removed sewage is further filtered through the filter ring and the filter element.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. The liquid inlet pipe conveys the sewage generated during the production of seasonings into the pre-separation cylinder. The ultrasonic transducer converts the energy of ultrasonic waves into vibrations, breaking the large-particle suspended solids in the sewage, and being able to perform crushing treatment on the large-particle suspended solids during pre-separation to prevent the large-particle suspended solids from blocking the pre-separation cylinder.

[0024] 2. The rotary joint connects the air delivery pipe to the air compressor. Compressed air enters the microbubble generator along the air delivery pipe. The rotation of the output shaft of the swirl motor drives the air delivery pipe and the microbubble generator to rotate. The microbubble generator generates a large number of tiny bubbles. The centrifugal force generated by the rotation of the swirl vane makes the sewage-containing form a swirl, enhancing the floating rate of oil droplets. The titanium-based coating electrode is energized with low-voltage direct current to generate hydroxyl radicals to decompose emulsified oil. Subsequently, the floating oil on the upper layer is pumped out through the floating oil suction pipe, and the emulsified oil can be fully treated through the cooperation of swirl air flotation and electrochemical assistance, improving the removal rate of emulsified oil.

[0025] In summary, the present invention can crush large - particle suspended solids during pre - separation to prevent the large - particle suspended solids from blocking the pre - separation cylinder, and can fully treat emulsified oil through the cooperation of hydrocyclone flotation and electrochemical assistance, improving the removal rate of emulsified oil and the sewage treatment efficiency.

Subsequently, the floating oil on the upper layer is pumped out through the floating oil suction pipe.
