Description

Technical Field

[0001] This utility model relates to the field of tea oil production technology, specifically to a tea oil production wastewater treatment device. Background Technology

[0002] In the tea oil production process, the pressing of tea seeds to extract oil, subsequent refining (deacidification, decolorization, deodorization), and equipment cleaning processes generate a large amount of wastewater containing specific pollutants. This wastewater not only contains a high concentration of tea seed oil residue (oil-like substances), but also contains suspended solids such as tea seed fragments and fibers, as well as biodegradable organic matter such as proteins and polysaccharides. If discharged directly without effective treatment, the oil will form a dense oil film on the water surface, hindering oxygen exchange between the water and the air, leading to oxygen deprivation and suffocation of aquatic organisms; suspended solids will settle at the bottom of the water body, polluting the bottom sediment and damaging the aquatic ecosystem; the decomposition of organic matter will consume dissolved oxygen in the water, causing the water to turn black and smelly. However, current tea oil production wastewater treatment devices mostly separate filtration and oil separation into two independent devices, requiring manual transfer of the filtered wastewater to the oil separation device. During the transfer process, wastewater is prone to spillage, causing secondary pollution. Therefore, we propose a tea oil production wastewater treatment device. Utility Model Content

[0003] The purpose of this utility model is to provide a tea oil production wastewater treatment device with the advantages of integrated filtration and oil separation. This solves the problem that most current tea oil production wastewater treatment devices separate filtration and oil separation into two independent devices, requiring manual transfer of the filtered wastewater to the oil separation device, which is prone to secondary pollution due to wastewater spillage during the transfer process.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tea oil production wastewater treatment device, comprising a base plate, a filter box fixedly connected to the top left end of the base plate, a filter screen provided in the inner cavity of the filter box, a feed inlet provided at the top left end of the filter box, an oil separator fixedly connected to the top right end of the base plate via a bracket, an oil separator plate fixedly connected to the right end of the inner cavity of the oil separator, a water outlet pipe provided at the upper right side of the oil separator, a pump fixedly connected to the right side of the filter box, the pump's suction port fixedly connected to the bottom right side of the inner cavity of the filter box via a pipe, the pump's outlet fixedly connected to the upper left side of the oil separator via a pipe, a drain pipe provided at the bottom right side of the inner cavity of the oil separator, and a solenoid valve installed in the inner cavity of the drain pipe.

[0005] Preferably, a stop block is fixedly connected to the right side of the filter screen, a motor is fixedly connected to the right end of the top of the filter box, and a rubber rod is fixedly connected to the output shaft of the motor.

[0006] Preferably, a battery box is fixedly connected to the top of the base plate, and a storage battery is fixedly connected to the inner cavity of the battery box.

[0007] Preferably, a toolbox is fixedly connected to the top of the base plate, and a partition is fixedly connected to the inner cavity of the toolbox.

[0008] Preferably, the bottom plate has fixing blocks fixedly connected to both the front and rear ends on the left and right sides, and bolts are provided on the fixing blocks.

[0009] Preferably, a timer is fixedly connected to the upper part of the front of the filter box, and a PLC controller is fixedly connected to the lower part of the front of the filter box. The input terminal of the PLC controller is electrically connected to the output terminal of the timer, and the output terminal of the PLC controller is electrically connected to the input terminals of the motor, solenoid valve and pump.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. The filter box at the top left of the base plate of this utility model provides a closed environment for wastewater pretreatment. The inlet at the top can be directly connected to the wastewater pipeline of tea oil production. After the wastewater enters, it is filtered by the filter screen in the inner cavity to accurately remove suspended solids such as tea seed fragments and fibers, avoiding blockage of subsequent pipelines or affecting the oil separation effect. The pump on the right side of the filter box can automatically transport the filtered wastewater to the oil separator at the top right of the base plate without manual transfer, realizing a continuous connection of "filtration-oil separation" and greatly improving the treatment efficiency. The oil separator plate at the right end of the inner cavity of the oil separator can block the floating oil and concentrate it on the left side of the tank, preventing it from overflowing from the outlet pipe with the treated water and ensuring complete separation of oil. The drain pipe at the bottom of the oil separator works with the solenoid valve to discharge the sludge at the bottom of the tank at regular intervals without manual pumping.

[0012] 2. The motor at the top right end of the filter box of this utility model can drive the rubber rod to rotate. When the rubber rod collides with the stop on the right side of the filter screen, it will cause the filter screen to vibrate slightly, shaking the suspended solids accumulated on the surface to the bottom of the filter box, without the need for manual disassembly and cleaning.

[0019] Example 1:

[0020] Please see Figure 1-3 As shown, this utility model provides a tea oil production wastewater treatment device, including a base plate 1. A filter box 4 is fixedly connected to the top left end of the base plate 1. A filter screen 18 is provided in the inner cavity of the filter box 4. An inlet 7 is opened at the top left end of the filter box 4. An oil separator 9 is fixedly connected to the top right end of the base plate 1 through a bracket. An oil separator plate 10 is fixedly connected to the right end of the inner cavity of the oil separator 9. A water outlet pipe 11 is provided at the upper right side of the oil separator 9. A pump 16 is fixedly connected to the right side of the filter box 4. The water inlet of the pump 16 is fixedly connected to the bottom right side of the inner cavity of the filter box 4 through a pipe.

A sewage pipe 12 is opened at the bottom right side of the inner cavity of the oil separator 9. A solenoid valve 13 is installed in the inner cavity of the sewage pipe 12.

[0021] The filter box 4 at the top left of the base plate 1 provides a closed environment for wastewater pretreatment. The inlet 7 at the top can be directly connected to the tea oil production wastewater pipeline. After the wastewater enters, it is filtered by the filter screen 18 in the inner cavity to accurately remove suspended solids such as tea seed fragments and fibers, avoiding blockage of subsequent pipelines or affecting the oil separation effect. The pump 16 on the right side of the filter box 4 can automatically transport the filtered wastewater to the oil separator 9 at the top right of the base plate 1 without manual transfer, realizing continuous connection of "filtration-oil separation" and greatly improving the treatment efficiency. The oil separator plate 10 at the right end of the inner cavity of the oil separator 9 can block the floating oil and concentrate it on the left side of the tank, preventing it from overflowing from the outlet pipe 11 with the treated water, ensuring complete separation of oil. The drain pipe 12 at the bottom of the oil separator 9 works with the solenoid valve 13 to discharge the sludge at the bottom of the tank at regular intervals without manual pumping.

[0022] Example 2:

[0023] Based on Embodiment 1, this utility model is as follows: Figure 1-3 As shown, a stop block 19 is fixedly connected to the right side of the filter screen 18, a motor 8 is fixedly connected to the right end of the top of the filter box 4, a rubber rod 17 is fixedly connected to the output shaft of the motor 8, a battery box 3 is fixedly connected to the top of the base plate 1, a storage battery is fixedly connected to the inner cavity of the battery box 3, a toolbox 2 is fixedly connected to the top of the base plate 1, a partition is fixedly connected to the inner cavity of the toolbox 2, fixing blocks 14 are fixedly connected to the front and rear ends of both sides of the base plate 1, bolts 15 are provided on the fixing blocks 14, a timer 6 is fixedly connected to the upper part of the front of the filter box 4, a PLC controller 5 is fixedly connected to the lower part of the front of the filter box 4, the input terminal of the PLC controller 5 is electrically connected to the output terminal of the timer 6, and the output terminal of the PLC controller 5 is electrically connected to the input terminals of the motor 8, the solenoid valve 13 and the pump 16.

[0024] In this technical solution, the motor 8 at the top right end of the filter box 4 can drive the rubber rod 17 to rotate. When the rubber rod 17 collides with the stop 19 on the right side of the filter screen 18, it will cause the filter screen 18 to vibrate slightly, shaking the suspended solids accumulated on the surface to the bottom of the filter box 4, without the need for manual disassembly and cleaning.

[0025] The working principle of this utility model is as follows: When using this device to treat tea oil production wastewater, firstly, the device is firmly fixed in the wastewater treatment area by fixing blocks 14 and bolts 15 on both sides of the base plate 1 to prevent displacement due to vibration during operation; connect the tea oil production wastewater pipeline to the feed inlet 7 at the top of the filter box 4. After the wastewater enters the filter box 4 from the feed inlet 7, it is filtered by the filter screen 18 in the inner cavity. Tea seed fragments, fibers and other suspended solids are intercepted, and the filtered wastewater is temporarily stored at the bottom of the filter box 4; when the cleaning time preset by the timer 6 is reached, the timer 6 sends a signal to the PLC controller 5, and the controller starts the motor 8 at the top of the filter box 4. The motor 8 drives the rubber rod 17 to rotate. The rubber rod 17 hits the stop block 19 on the right side of the filter screen 18, causing the filter screen 18 to vibrate. The system shakes off the suspended solids accumulated on the surface. Then, the PLC controller 5 starts the pump 16 on the right side of the filter box 4. The pump 16 transports the filtered wastewater to the grease trap 9 through the pipeline. The wastewater flows slowly in the grease trap 9, and the grease gradually floats to the surface and is blocked by the grease trap 10 on the left side of the tank. The treated clean water is discharged from the outlet pipe 11 at the upper right side of the grease trap 9. When the preset sewage discharge time is reached, the PLC controller 5 opens the solenoid valve 13 in the sewage discharge pipe 12 at the bottom of the grease trap 9 to discharge the sludge deposited at the bottom of the tank. In case of a sudden power failure, the battery in the battery box 3 at the top of the base plate 1 automatically supplies power to the core components to ensure that the current processing procedure is completed. During routine maintenance, spare parts can be taken from the toolbox 2 to replace the damaged filter screen 18, or to repair the pump 16 and the solenoid valve 13.
