DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0016] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0017] like Figures 1 to 4 As shown, a water treatment device provided by an embodiment of the present invention comprises a filter box 1 connected at both ends and an oil condensation assembly arranged at the water outlet side of the filter box 1, wherein the oil condensation assembly comprises an oil condensation box 2 and a condensation tube bed 5 arranged in the oil condensation box 2; The condensate tank 2 is provided with a water inlet chamber 210, a buffer chamber 230 and a static flow chamber 220 along the water flow direction. The water inlet chamber 210 is connected with the buffer chamber 230 at the bottom and separated at the liquid surface. The buffer chamber 230 is separated with the static flow chamber 220 at the bottom and connected at the liquid surface. The condenser tube bed 5 is arranged at the liquid level position above the static flow chamber 220. The condenser tube bed 5 includes a plurality of horizontally spaced heat-conducting condenser tubes 510. The heat-conducting condenser tubes 510 are connected to the cold end of the semiconductor condenser plate and are made of heat-conducting material.

[0018] In an embodiment of the present invention, a water treatment device is provided, which is suitable for sewage management in household scenarios, especially the discharge and treatment of kitchen wastewater. Through the staggered arrangement of the water inlet chamber 210, the buffer chamber 230 and the static flow chamber 220, the discharge of sewage is buffered and a small amount of storage is performed, so that the drainage effect is different from the high flow rate state of direct discharge in the prior art, and a relatively stable liquid level equilibrium state can be maintained in the static flow chamber 220, so that a small amount of cooling is performed through the heat-conducting condenser to quickly condense the suspended oil on the water surface, so that it can be controllably agglomerated and collected before being discharged into the sewage pipe, which can effectively avoid the blockage of the sewage pipe caused by the condensation of a large amount of oil entering the pipe.

[0019] In one embodiment of the present invention, in specific use, the user installs it between the bottom of the drainage pool and the sewage pipe. When the user generates and starts to discharge sewage, the water flow sensor installed in the pipe is triggered to control the heat-conducting condenser 510 to perform cooling (the hot end is connected to the side of the water inlet chamber 210, which can effectively prevent the grease from condensing prematurely. The specific cooling level here can also be divided according to needs and selected by the user based on the usage scenario. For example, the condensation and solidification temperature of animal fats is much higher than that of vegetable fats, so multiple gears can be set based on this). At the same time, the sewage is decelerated through the arc-shaped water inlet chamber 210 and enters the water inlet chamber 210 connected to the buffer chamber at the bottom. The sewage accumulates in the flushing chamber 230 and overflows into the static flow chamber 220 after the accumulated space is filled. During the overflow process, the sewage contacts the heat-conducting condenser tube 510 and partially condenses. When the liquid levels in the three chambers are balanced, the flow of the entire liquid flows slowly below the liquid surface (the horizontal cross-sectional area of ​​the chamber is larger, far exceeding the total sewage flow rate per unit time), making the liquid in the chamber in a relatively calm state. The temperature in the static flow chamber 220 decreases, causing the grease to condense and float up, and contact the heat-conducting condenser tube 510 at the liquid surface to gather and condense, thereby completing the degreasing operation of the sewage, reducing the grease content in the sewage finally discharged into the sewage pipe, and reducing the possibility of clogging the pipe.

[0020] like Figure 3 , Figure 4 As shown, as a preferred embodiment of the present invention, the condenser tube bed 5 further includes a grease scraper 520; The grease scraper 520 is a vertically arranged plate-shaped structure, and is provided with a plurality of openings corresponding to the heat-conducting condensing tubes 510 in a horizontal direction. The grease scraper 520 is slidably arranged on the heat-conducting condensing tubes 510 through the plurality of openings. The condensate tank 2 is provided with a receiving chamber 6 on one side of the static flow chamber 220, and the receiving chamber 6 is connected with the static flow chamber 220 at the horizontal plane where the condensation tube bed 5 is located, and is also connected with the static flow chamber 220 through a plurality of through holes at the bottom position; The condenser tube bed 5 also includes a push-pull connecting plate 530 arranged in the accommodating cavity 6. The push-pull connecting plate 530 is fixedly connected to the grease scraper 520. When the push-pull connecting plate 530 is horizontally displaced, the grease scraper 520 slides along the heat-conducting condenser tube 510.

[0021] In one embodiment of the present invention, during long-term use, more and more grease will condense on the surface of the thermal condenser tube 510. In order to avoid accumulation and blockage and ensure the continuous progress of subsequent degreasing work, a grease scraper 520 is provided. After a period of use, the solid grease on the surface of the thermal condenser tube 510 can be quickly removed by pulling the grease scraper 520, thereby ensuring the normal progress of subsequent degreasing operations; the accommodating chamber 6 is used to receive the scraped solid grease, and based on the inclined sloped bottom setting, the grease cleaning process can be realized more conveniently.

[0022] like Figure 1 , Figure 3 , Figure 5 As shown, as another preferred embodiment of the present invention, it also includes a drainage balance component 4, and the drainage balance component 4 includes: A water balance chamber 410, which is arranged on both sides of the static flow chamber 220 and is connected to the bottom of the static flow chamber 220. The water balance chamber 410 is provided with a balance drain pipe 420 connected to the main drain pipe at the horizontal plane where the condenser tube bed 5 is located. When the water level of the static flow chamber 220 exceeds the condenser tube bed 5, the water level balance control is performed through the balance drain pipe 420; The drainage drain pipe 430 is respectively arranged at the bottom of the static flow chamber 220 and the buffer chamber 230, and is connected to the main drainage pipe. The drainage drain pipe 430 is provided with a drainage control valve at the connection with the main drainage pipe to control the connection state with the main drainage pipe.

[0023] In one embodiment of the present invention, a drainage balance component 4 is added. During the condensation process, because the space in the chamber is limited and sewage is continuously generated, and in order to ensure that the heat-conducting condenser tube can always be kept at the liquid level to achieve the most efficient grease condensation effect, it is also necessary to ensure the outflow of sewage in the static flow chamber 220. In the static flow chamber 220, due to the slow flow rate of the liquid and the decrease in temperature, the grease will be in a floating state or condensed state. Therefore, a pipeline is set at the bottom of the static flow chamber 220 and guided to an additional partition (referring to the liquid Therefore, a balancing drain pipe 420 having the same height as the heat-conducting condensing tube 510 can be set in the water balancing chamber 410, and then the wastewater from which grease has been removed can be guided to flow out slowly to maintain the water level balance in the static flow chamber 220; the drainage drain pipe 430 here is used to completely empty all the wastewater in the static flow chamber 220 and the buffer chamber 230, and it is controlled by the drainage control valve 440. The drainage control valve 440 can be set to an electrically controlled structure, and the user can control the drainage with one button when needed.

[0024] like Figure 1 , Figure 2,as well as Figures 6 to 8 As shown, as a preferred embodiment of the present invention, the interior of the filter box 1 is a cylindrical cavity structure arranged horizontally, and an upper water inlet opening and a lower discharge opening are respectively arranged at diagonal positions passing through the center of the circle; The filter box 1 is provided with a filter screen 110 in an arc-shaped structure at the position of the horizontal projection plane of the upper water inlet opening, and the filter screen 110 coincides with the top opening of the condensate tank 2; The filter box 1 is further provided with a cleaning wheel 120 that rotates with the filter box 1 . The cleaning wheel 120 includes a plurality of comb-shaped cleaning plates 121 distributed on the circumference. The ends of the comb-shaped cleaning plates 121 are slidably fitted with the surface of the filter screen 110 .

[0025] Furthermore, the filter box 1 is also provided with a maintenance comb 130; The maintenance comb 130 includes a plurality of comb teeth structures staggered with the comb-shaped cleaning plate. The maintenance comb 130 is slidably arranged along an inclined guide rail 140. The guide rail 140 is arranged to intersect with the comb-shaped cleaning plate 121, and the end thereof exceeds the rotation radius of the comb-shaped cleaning plate 121. The guide rail 140 is magnetically matched with the maintenance comb 130 , and the magnetic matching direction points to the inner diameter direction of the cleaning wheel 120 . When the maintenance comb 130 is separated from the comb-shaped cleaning plate 121 , the maintenance comb 130 slides toward the inside of the cleaning wheel 120 .

[0026] Furthermore, the filter box 1 is further provided with a debris box 3 below the lower discharge opening. The debris box 3 is arranged at a height higher than the condenser tube bed 5 , and the debris box 3 is a push-pull detachable structure.

[0027] In one embodiment of the present invention, the structure of the filter box 1 is further described. It is mainly used for the preliminary filtration treatment of kitchen waste and domestic sewage. The larger solid particles therein are filtered through the filter to prevent them from entering the static flow chamber 220 and other chambers. In the process of filtering, solid waste will gradually accumulate, so it is necessary to clean it to ensure the sewage passability of the filter. A rotating cleaning wheel 120 is used here. The cleaning wheel 120 rotates to scrape off the solid dirt on the surface of the filter and send it into the debris box 3. At the same time, in order to avoid the dirt in Dirt is accumulated on the comb-shaped cleaning plate 121 of the cleaning wheel 120, and a maintenance comb 130 is additionally provided. The maintenance comb 130 and the comb-shaped cleaning plate 121 are arranged alternately, so when the maintenance comb 130 slides on the comb-shaped cleaning plate 121, the dirt on it can be brushed off. Here, the maintenance comb 130 is slidably arranged on an inclined track, so it can be pushed to slide on the guide rail under the rotation of the cleaning wheel 120, and at the same time, after detaching from the comb-shaped cleaning plate 121, it can be quickly reset under the action of magnetic cooperation for cleaning the next comb-shaped cleaning plate 121.

[0028] An embodiment of the present invention further provides a water treatment process, which is applied to a water treatment device and is characterized in that it specifically includes: The kitchen waste and domestic sewage enters the condensate tank 2 after passing through the filter box 1, triggering the water flow monitoring sensor to control the heat conduction condensation pipe 510 to start and cool down; After the kitchen waste and domestic sewage are decelerated through the water inlet chamber 210, they are stored in the buffer chamber 230 and overflow into the static flow chamber 220 after exceeding the maximum water level; In the static flow chamber 220, the kitchen waste and domestic sewage at the liquid surface contacts the heat-conducting condensation tube 510 and causes the suspended grease to condense and adhere, so as to remove the condensable grease in the kitchen waste and domestic sewage.
