Description

Technical Field

[0001] This utility model relates to the technical field of waste purification, specifically a wastewater purification device for a tomato sauce production line. Background Technology

[0002] Tomato sauce, a common food condiment, is mainly composed of tomato concentrate. It is typically made from ripe red tomatoes, which are washed, peeled, crushed, pulped, and seeded before being heated at high temperatures and then packaged. The tomato sauce production process generates wastewater containing sludge from peels and seeds. This wastewater needs to be dewatered to facilitate subsequent treatment or resource utilization.

[0003] Chinese patent CN217025558U discloses a multi-stage dehydration filter tank for tomato sauce. The device uses a filter screen to concentrate impurities in the wastewater into a collection box, then allows the wastewater to pass through multiple layers of activated carbon adsorption layers to adsorb color, and finally disinfects it in a disinfection tank.

[0004] However, this technical solution has the following drawbacks: it relies solely on a filter screen and activated carbon adsorption layer to filter wastewater. While it can separate impurities from the wastewater, it cannot effectively dehydrate the filtered waste, resulting in the separated waste always maintaining a high moisture content. Due to the loose structure and poor stability of the high-moisture waste, even if it is collected, if it is exposed to rainwater or leakage during temporary storage or transportation, the pollutants in the waste are easily dissolved and spread to the surrounding water bodies or soil, causing secondary pollution. This poses a significant obstacle to subsequent treatment and resource utilization. Utility Model Content

[0005] The purpose of this invention is to provide a wastewater purification device for tomato sauce production lines, in order to solve the problem that existing tomato sauce wastewater treatment devices can only filter and separate waste materials in wastewater, but cannot effectively dehydrate them. This results in the high moisture content of loose waste materials being prone to the spread of pollutants due to leakage and rainwater erosion during subsequent processing or transportation, thereby affecting the environment and subsequent resource utilization.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a wastewater purification device for a tomato sauce production line, comprising a collection box, the collection box being disposed behind a sedimentation tank, the bottom surface of the collection box being inclined, the collection box being connected to the sedimentation tank via a connecting pipe, and a lifting pump being disposed at the end of the connecting pipe, a limit strip being fixed to the inner wall of the collection box, a mounting frame being fixed to the top surface of the collection box, two mounting holes being provided on the top surface of the mounting frame, and a dewatering component being disposed above the collection box for dewatering the waste material.

[0007] Preferably, the dehydration assembly includes two cylinders, which are respectively fixed in two mounting holes. A pressing plate is fixed to one end of the cylinder telescopic rod. A sealing ring is fixed to the outer wall of the pressing plate. Limiting holes are opened at the four corners of the top surface of the pressing plate. A load-bearing plate is placed on the top surface of the limiting strip. Limiting posts are fixed at the four corners of the top surface of the load-bearing plate. The limiting posts are slidably connected to the limiting holes. A number of fixing holes are opened on the top surface of the load-bearing plate. A filter screen is fixed to the inner wall of the fixing holes.

[0008] Preferably, the top surface of the pressing plate is provided with a mounting groove, and a heating plate is fixed to the inner wall of the mounting groove.

[0009] Preferably, a protective cover is suspended on the top surface of the sedimentation tank, and a suction fan is fixed on the top surface of the protective cover, with the output end of the suction fan extending into the protective cover.

[0010] Preferably, a sealing gasket is fixed to the top surface of the sedimentation tank, and the top surface of the sealing gasket is in contact with the bottom surface of the protective cover.

[0011] Preferably, the sedimentation tank has receiving holes on both the left and right sides, and a shell is fixed to the inner wall of the receiving hole, with a plurality of spray heads fixed on the shell.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Through the coordinated action of cylinders, pressing plates, and load-bearing plates, waste materials in the wastewater discharged from the sedimentation tank can be pressed and dewatered. This process significantly reduces the moisture content of the waste materials, making the originally loose waste materials more compact. With the reduced moisture content and compact structure of the waste materials, the pollutants are firmly locked inside. Even if leakage or rainwater erosion occurs during subsequent treatment or transportation, the pollutants are difficult to dissolve, thus effectively preventing them from spreading into water bodies or soil, improving the practicality of the dewatering component.

[0014] Second, the cooperation of the limiting pins and limiting holes ensures greater stability during the up-and-down movement of the pressing plate, allowing it to move strictly along the predetermined trajectory and effectively preventing positional deviation due to mechanical stress. This guarantees the stable operation of the pressing and dewatering process, thereby improving the dewatering efficiency of waste materials and providing convenient conditions for subsequent waste treatment or resource utilization.

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-4 As shown, a wastewater purification device for a tomato sauce production line includes a collection box 1, which is located behind a sedimentation tank 2. The bottom surface of the collection box 1 is inclined. The collection box 1 is connected to the sedimentation tank 2 via a connecting pipe, and a lift pump is installed at the end of the connecting pipe. A limit strip 3 is fixed to the inner wall of the collection box 1. A mounting frame 4 is fixed to the top surface of the collection box 1, and two mounting holes 5 are opened on the top surface of the mounting frame 4. A dewatering assembly is installed above the collection box 1 for dewatering the waste. The dewatering assembly includes... Two cylinders 6 are fixed in two mounting holes 5 respectively. One end of the telescopic rod of the cylinder 6 is fixed with a pressing plate 7. A sealing ring 8 is fixed on the outer wall of the pressing plate 7. Limiting holes 9 are opened at the four corners of the top surface of the pressing plate 7. A load-bearing plate 10 is placed on the top surface of the limiting strip 3. Limiting posts 11 are fixed at the four corners of the top surface of the load-bearing plate 10. The limiting posts 11 are slidably connected to the limiting holes 9. Several fixing holes 12 are opened on the top surface of the load-bearing plate 10. A filter screen 13 is fixed on the inner wall of the fixing holes 12.

[0022] During use, when the sewage lift pump transports the water-containing waste in the sedimentation tank 2 to the collection box 1, the suspended solids are deposited on the surface of the load-bearing plate 10 through the interception of the filter screen 13, forming a waste layer. Subsequently, the cylinder 6 drives the pressing plate 7 to carry out mechanical pressing and dehydration. The cylinder 6 drives the pressing plate 7 to move downward and close to the load-bearing plate 10. The limiting column 11 and the limiting hole 9 on the load-bearing plate 10 achieve precise positioning. During the pressurization process, capillary water penetrates the filter screen 13 under the pressure and flows into the collection box 1. After the set pressure holding period is completed, the cylinder 6 performs the return action to reset the pressing plate 7. The staff can then carry out harmless disposal of the low-moisture waste cake formed on the load-bearing plate 10.

[0023] The combination of cylinder 6, pressing plate 7, and load-bearing plate 10 allows for the pressing and dewatering of waste materials discharged from sedimentation tank 2. This significantly reduces the moisture content of the waste materials, making them more compact and facilitating subsequent treatment or resource utilization. It also effectively prevents pollutants from spreading into water bodies or soil due to leakage or rainwater erosion, thus improving the practicality of the dewatering component. The cooperation between limiting post 11 and limiting hole 9 ensures greater stability during the up-and-down movement of pressing plate 7, allowing it to move along a predetermined trajectory. This effectively prevents the pressing plate 7 from shifting due to mechanical stress, thereby improving its stability and ultimately increasing the dewatering efficiency of the waste materials.

[0024] like Figures 1-4 As shown, the top surface of the pressing plate 7 is provided with an installation groove 14, the inner wall of the installation groove 14 is fixed with a heating plate 15, the top surface of the sedimentation tank 2 is suspended with a protective cover 16, the top surface of the protective cover 16 is fixed with a suction fan 17, and the output end of the suction fan 17 extends into the protective cover 16.

[0025] During use, the heating plate 15 heats the waste material when it is pressed by the pressing plate 7, promoting the evaporation of free water and some bound water in the waste material, thereby directly reducing the volume of the waste material and assisting the dehydration component in dehydrating the waste material. The suction fan 17 absorbs and guides the gas generated by wastewater fermentation in the sedimentation tank 2, allowing the gas generated by wastewater fermentation to be collected and treated centrally, thereby preventing the gas from diffusing into the air and causing air pollution.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, a sealing gasket 18 is fixed on the top surface of the sedimentation tank 2. The top surface of the sealing gasket 18 is in contact with the bottom surface of the protective cover 16. Accommodation holes 19 are provided on both the left and right sides of the sedimentation tank 2. A shell 20 is fixed on the inner wall of the accommodation hole 19. Several spray heads 21 are fixed on the shell 20.

[0027] During use, the sealing gasket 18 increases the seal between the sedimentation tank 2 and the protective cover 16, blocking the gas generated by wastewater fermentation in the sedimentation tank 2 and effectively preventing the gas from leaking into the air, thus ensuring the safety of the working environment. The spray nozzle 21 can be used to clean the sedimentation tank 2, saving labor costs associated with manual cleaning and effectively preventing waste materials in the wastewater from adhering to the inner wall of the sedimentation tank 2, thereby ensuring the cleanliness of the internal cavity of the sedimentation tank 2.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
