Technical Field
[0001] This utility model relates to the field of purification equipment technology, and in particular to a commercial kitchen oil-water separation and purification device. Background Technology
[0002] In the daily operation of commercial kitchens, a large amount of wastewater containing grease is generated. If this wastewater is discharged directly, it will not only cause sewer blockage, but may also pollute the environment. Therefore, commercial kitchen oil-water separation and purification devices have emerged. Their core function is to effectively separate oil and water in wastewater to meet environmental protection and hygiene requirements.
[0003] Existing oil-water separation and purification devices typically have two drawbacks. First, some devices lack a heating structure, and under low-temperature conditions, grease easily solidifies and adheres to the surface of the separation components, leading to a decrease in separation efficiency. Second, while some devices with heating functions improve fluidity, the odors generated by grease decomposition during the heating process can diffuse along the pipes into the kitchen space, or be released in a concentrated manner when the equipment is opened for cleaning, seriously affecting the comfort of the operating environment.
[0004] Therefore, in view of the two shortcomings of the existing oil-water separation and purification devices mentioned above, a commercial kitchen oil-water separation and purification device can be designed. By setting a heating plate at the bottom of the separation box to effectively prevent grease from solidifying, and by installing gas purification components at multiple air outlets in the separation cover to neutralize the odors generated during the heating process, the above problems can be easily solved. Summary of the Invention

[0016] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Example
[0017] like Figures 1-6 As shown, a commercial kitchen oil-water separation and purification device includes a separation box 1, a heating plate 2, an oil-separating baffle 3, a separation cover 4, and a gas purification component 5. The bottom of the separation box 1 has three sets of separation tanks 101 linearly arranged for separating oil and water. Two sets of water-separating baffles 102 are provided between the three sets of separation tanks 101 to separate them. Above the center of the three sets of separation tanks 101, three sets of oil-separating baffles 3 are provided to cooperate with the water-separating baffles 102. The lower end of the oil-separating baffles 3 extends to the middle section of the separation tanks 101. A floating oil tank 104 connecting the three sets of oil-separating baffles 3 is provided between them. Below the separation box 1 is a heating plate 2 to prevent grease from solidifying. Above the separation box 1 is a separation cover 4 for sealing the separation box 1. The surface of the separation cover 4 has three sets of air outlets 401 corresponding to the floating oil tanks 104. Inside the air outlets 401 is a gas purification component 5 for purifying the gas.
[0018] The gas purification component 5 includes a purification plug 501, a filling groove 502 is provided inside the purification plug 501, and multiple sets of air outlets 503 are evenly provided at the bottom of the filling groove 502. A fragrance filter 506 is installed inside the filling groove 502. Through the design of multiple sets of air outlets 503, the gas can fully contact the fragrance filter 506 inside the filling groove 502, ensuring sufficient odor purification.
[0019] A limiting ring 504 corresponding to the air outlet 401 is fitted on the upper outer end of the purification plug 501. A cover groove 505 is opened at the upper edge of the purification plug 501. A mesh cover 507 is installed inside the cover groove 505. Through the cooperation of the limiting ring 504 and the air outlet 401, the purification plug 501 can be accurately positioned and securely installed. The mesh cover 507 can prevent external debris from entering the filling groove 502 and also play a certain role in fixing the fragrance filter 506.
[0020] The front edge of the separation cover 4 is provided with an oil pipe connector 402 that connects to the first set of separation tanks 101. The upper end of the oil pipe connector 402 is provided with a butterfly check valve 403, and the upper end of the check valve is provided with a connecting pipe 404. The bottom of the rear side wall of the separation box 1 is provided with a water outlet connector 105 that connects to the third set of separation tanks 101. The butterfly check valve 403 can effectively prevent the backflow of odorous gases and grease. The connecting pipe 404 can be connected to the drain pipe of the kitchen sink. The water outlet connector 105 can be connected to a hose to the kitchen drain hole.
[0021] Both sides of the oil separator baffle 3 are provided with fixing frames 301. Bamboo charcoal adsorption plates 302 are fitted inside the fixing frames 301. The inner side walls of the separation box 1 are provided with multiple sets of fixing clips 103 corresponding to the oil separator baffle 3. The bamboo charcoal adsorption plates 302 have a strong adsorption capacity, which can adsorb the tiny oil droplets, impurities and some odor molecules remaining in the separation process, further improving the quality of oil-water separation. The fixing frames 301 facilitate the replacement of the bamboo charcoal adsorption plates 302, and the fixing clips 103 facilitate the fixing and removal of the oil separator baffle 3.
[0022] The heating plate 2 has a heating groove 201 on its surface and a heating ceramic plate 202 inside the heating groove 201. The lower end of the separation box 1 is inserted and fixed to the heating groove 201. The heating ceramic plate 202 has the advantages of uniform heating, high thermal efficiency and long service life, which can provide stable and efficient heating for the separation box 1 and ensure that the grease in the separation box 1 always maintains good fluidity.
[0023] A digital display screen 203 is provided on one side of the front end of the heating plate 2, and multiple control buttons 205 are provided on the other side of the front end of the heating plate 2. A temperature sensor 204 is provided between the digital display screen 203 and the multiple control buttons 205. A charging connector 206 is provided at the center of the front end of the heating plate 2. The external ambient temperature can be monitored in real time through the temperature sensor 204, the heating temperature of the heating plate 2 can be displayed through the digital display screen 203, and the heating temperature can be precisely adjusted through the control buttons 205 to achieve precise control of the heating process. The charging connector 206 facilitates charging of the heating plate 2.
[0024] During operation, the staff first connects the water outlet connector 105 at the rear of the separation box 1 to the kitchen drain hole through a hose to ensure that the separated water is discharged smoothly. Then, the connecting pipe 404 above the separation cover 4 is connected to the kitchen sink drain pipe. The power is then connected through the charging connector 206 of the heating plate 2. The heating temperature is set through the control button 205, and the temperature is displayed in real time on the digital display screen 203.
[0025] Oily wastewater flows into the first separation tank 101 through the connecting pipe 404, and then flows into the second and third separation tanks 101 through the water separation baffle 102. The oil separation baffle 3 blocks the floating oil, causing the grease to accumulate on the surface of the oil floating tank 104. The separated clean water is discharged from the water outlet 105. The heating ceramic plate 202 continuously heats the bottom of the separation box 1 to prevent the grease from solidifying. The bamboo charcoal adsorption plate 302 adsorbs residual oil droplets and odors.
[0026] The odorous gas generated by heating enters the gas purification component 5 through the gas outlet 401 of the separation cover 4, and is discharged after being neutralized by the fragrance filter 506. The separation cover 4 is opened regularly to clean the floating oil, and the bamboo charcoal adsorption plate 302 or the fragrance filter 506 is replaced.
[0027] Its working principle is as follows: After oily wastewater flows into the first set of separation tanks 101, due to the density difference between oil and water, the oil gradually floats to the top. The oil separation baffle 3 and the water separation baffle 102 guide the wastewater through the three sets of separation tanks 101 in sequence. During this process, the oil continuously floats and accumulates in the oil floating tank 104, while the water is discharged from the third set of separation tanks 101 through the water outlet 105. The heating ceramic plate 202 in the heating tank 201 continuously heats up, providing stable heat to the separation box 1, preventing the oil from solidifying at low temperatures and ensuring its flow. Odor-causing gases generated during heating in the oil floating tank 104 are discharged through the vent 401 on the separation cover 4. When the gas passes through the purification plug 501, it comes into full contact with the fragrance filter 506 in the filling tank 502 through the vent 503, thus purifying the odor. The bamboo charcoal adsorption plates 302 on both sides of the oil separating baffle 3 further adsorb the tiny oil droplets, impurities, and some odor molecules remaining during the separation process, improving the quality of oil-water separation. The butterfly check valve 403 prevents odor-causing gases and sewage from flowing back into the pipeline.
[0028] Its beneficial effects are significant. Through the design of the separation tank 101, water separation baffle 102, oil floating tank 104 and oil separation baffle 3, oil and water can be fully separated, effectively improving the oil-water separation efficiency, ensuring smooth drainage system, and reducing the risk of sewer blockage. The heating plate 2, combined with the heating ceramic plate 202, can continuously and stably heat the separation box 1 in a low-temperature environment, ensuring that the grease always maintains good fluidity and avoiding the decrease in separation efficiency due to grease solidification, thus expanding the range of application environments of the device. Through the cooperation of the fragrance filter 506 and the air outlet 503 in the gas purification component 5, and the assistance of the bamboo charcoal adsorption plates 302 on both sides of the oil separation baffle 3, the dual action effectively purifies the odor generated during the heating process, improves the kitchen operating environment, and enhances the comfort of the staff. The butterfly check valve 403 prevents the backflow of odors and grease. The limiting ring 504 cooperates with the air outlet 401 to facilitate the installation of the purification plug 501. The fixing frame 301 and the fixing clip 103 facilitate the replacement of the bamboo charcoal adsorption plate 302 and the disassembly and assembly of the oil separation baffle 3.
