Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology for quick-frozen food processing, specifically a wastewater treatment device for quick-frozen food processing. Background Technology

[0002] The food industry is extremely complex, encompassing processes such as sugar refining, brewing, meat processing, and dairy production. The wastewater discharged from these processes contains organic matter, exhibits high oxygen consumption, and carries a large amount of suspended solids. Wastewater from animal-based food processing also contains animal excrement, blood, fur, grease, and may contain pathogens, thus having a very high oxygen consumption and being far more polluting than wastewater from plant-based food processing.

[0003] The specific design and structure of wastewater treatment equipment for frozen food processing may vary depending on the manufacturer and application requirements, but generally they include the following key components: screens and equalization tanks, etc. The screen structure is a metal grid or screen with varying gap sizes. Mechanical screens are also equipped with automatic slag removal devices to intercept large particles such as vegetable leaves and packaging fragments, preventing blockage of subsequent pipes and equipment. The equalization tank is usually a large pool with built-in agitators or aeration devices. Its function is to balance water quality and quantity, stabilize the pH value, organic matter concentration and other indicators of the wastewater, and avoid impacting subsequent treatment.

[0004] Traditional equipment uses fixed screens, which cannot screen and clean impurities simultaneously. The machine must be stopped to clean the clogged screens, resulting in low wastewater treatment efficiency and limited processing capacity per unit time. Traditional equipment flushing systems mostly use fixed nozzles with fixed flushing angles, which cannot cover the entire screen area and have flushing blind spots. This makes it impossible to effectively remove impurities from screen gaps and corners, resulting in poor flushing effect and the inability to fundamentally solve the screen clogging problem. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a wastewater treatment device for quick-frozen food processing.

[0006] The technical solution adopted by this utility model to solve its technical problem is a wastewater treatment device for quick-frozen food processing, including a box body. A feeding hopper is provided at the top of the box body, and an arc-shaped processing chamber is provided below the feeding hopper. A screening shaft is rotatably arranged inside the arc-shaped processing chamber. Three screening plates are arrayed on the screening shaft. A driven gear is provided at the top of the screening shaft. A first motor bracket is provided on the side of the box body. A screening motor is mounted on the first motor bracket. A transmission gear is provided at the output end of the screening motor, and the transmission gear meshes with the driven gear. The arc-shaped processing chamber... The unit is equipped with a rinsing tank, within which a rinsing rod is rotatably mounted. Several rinsing water guns are mounted on the rinsing rod. A second motor bracket is mounted on the side of the rinsing tank, and an adjusting motor is mounted on the second motor bracket. The output end of the adjusting motor is fixedly connected to the top of the rinsing rod. A mounting plate is mounted on the side of the unit, and a water collection tank is mounted on the mounting plate. A rinsing water pump is mounted on the side of the water collection tank, and a water pump has a suction pipe, the other end of which is connected to the water collection tank. A water delivery pipe is mounted on the rinsing water pump, the other end of which is connected to the rinsing rod.

[0007] Preferably, the arc-shaped processing chamber has a debris collection chamber on its side, a drain plate at the bottom of the debris collection chamber, a wastewater chamber below the drain plate, and a hinged sealing door at the top of the debris collection chamber with a handle. The drain plate quickly separates the trapped debris from the wastewater, facilitating subsequent processing. The hinged sealing door, combined with the handle, makes it easy to clean debris regularly, reducing odor emissions and meeting the hygiene standards of the food processing industry.

[0008] Preferably, limit plates are symmetrically arranged in the rinsing tank. The two limit plates are used to limit the position of the rinsing water gun. In a high-frequency vibration environment, the limit plates fix the position of the rinsing rod by physical constraint, so as to avoid pipe twisting or loosening of the interface caused by vibration of the water gun, and reduce water leakage accidents.

[0009] Preferably, the bottom of the arc-shaped treatment chamber is provided with a drain hole, and below the drain hole is a wastewater chamber. The wastewater chamber is provided with a drain valve. The screened wastewater is collected into the wastewater chamber through the drain hole for subsequent biochemical treatment.

[0010] Preferably, the tops of the three screening plates are designed to fit snugly against the bottom of the arc-shaped treatment chamber. The complete fit between the tops of the screening plates and the bottom of the arc-shaped treatment chamber can prevent debris from accumulating in the gaps at the bottom of the chamber during wastewater treatment, ensuring that all wastewater and impurities are filtered through the screening plates and reducing residue.

[0011] Preferably, the screening motor, regulating motor, and rinsing water pump are all connected to an external controller. The controller is used to control the start and stop of the screening motor, regulating motor, and rinsing water pump. The controller can accurately set the start and stop times of the screening motor, regulating motor, and rinsing water pump to achieve coordinated operation of the equipment.

[0012] The advantages of this utility model are: by rotating three screening plates in an arc-shaped treatment chamber, continuous screening of wastewater is achieved, avoiding the intermittent working mode of traditional fixed screens and improving treatment efficiency; the flushing rod is equipped with a flushing water gun, which is driven to rotate by an adjustable motor and the flushing angle is precisely controlled by a limit plate to achieve full coverage of the screening plates and remove impurities that clog the screening plates.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0016] Please see Figure 1-5 As shown, a wastewater treatment device for quick-frozen food processing includes a housing 1, a feeding hopper 2 at the top of the housing 1, an arc-shaped processing chamber 3 below the feeding hopper 2, a screening shaft 4 rotatably mounted inside the arc-shaped processing chamber 3, three screening plates 5 arrayed on the screening shaft 4, a driven gear 6 at the top of the screening shaft 4, a first motor bracket 7 on the side of the housing 1, a screening motor 8 mounted on the first motor bracket 7, and a transmission gear 9 at the output end of the screening motor 8, the transmission gear 9 meshing with the driven gear 6; During operation, in order to treat the wastewater from frozen food processing, the wastewater enters the arc-shaped treatment chamber 3 through the feed hopper 2 and flows to the bottom of the chamber under gravity. The screening motor 8 drives the transmission gear 9 and the driven gear 6, which in turn drives the screening shaft 4 to rotate, causing the three screening plates 5 to rotate synchronously. When the wastewater flows through the screening plates 5, impurities with a particle size larger than the screen mesh size, such as vegetable leaves, minced meat, and packaging fragments, are intercepted. The wastewater then flows into the wastewater chamber 15 through the drain hole 10. When the intercepted impurities rotate with the screening plates 5 to the top of the debris collection chamber 11, they fall into the chamber due to gravity and the pushing action of the screening plates 5. The drain plate 12 causes the water in the debris to drip naturally into the wastewater chamber 15, achieving preliminary solid-liquid separation. The debris is cleaned periodically through the sealing door 13.

[0017] The arc-shaped treatment chamber 3 has a rinsing trough 21 on its side. A rinsing rod 22 is rotatably mounted inside the rinsing trough 21. Several rinsing water guns 23 are mounted on the rinsing rod 22. A second motor bracket 24 is mounted on the side of the rinsing trough 21. An adjusting motor 25 is mounted on the second motor bracket 24. The output end of the adjusting motor 25 is fixedly connected to the top of the rinsing rod 22. A mounting plate 16 is mounted on the side of the chamber 1. A water collection tank 17 is mounted on the mounting plate 16. A rinsing water pump 18 is mounted on the side of the water collection tank 17. A water pump 18 is mounted on the rinsing water pump 18. A water suction pipe 19 is mounted on the rinsing water pump 18. The other end of the water suction pipe 19 is connected to the water collection tank 17. A water delivery pipe 20 is mounted on the rinsing water pump 18. The other end of the water delivery pipe 20 is connected to the rinsing rod 22.

[0018] The arc-shaped processing chamber 3 has a debris collection chamber 11 on its side. The bottom of the debris collection chamber 11 is provided with a drain plate 12. Below the drain plate 12, a wastewater chamber 15 is provided. The top of the debris collection chamber 11 is hinged with a sealing door 13. The sealing door 13 is provided with an opening handle 14.

[0019] The rinsing tank 21 is symmetrically provided with limiting plates 26. The two limiting plates 26 are used to limit the rinsing water gun 23. The bottom of the arc-shaped treatment chamber 3 is provided with a drain hole 10. Below the drain hole 10 is a wastewater chamber 15. A drain valve 27 is provided on the wastewater chamber 15.

[0020] The tops of the three screening plates 5 are designed to fit into the bottom of the arc-shaped processing chamber 3. The screening motor 8, the regulating motor 25 and the rinsing water pump 18 are all connected to an external controller, which is used to control the start and stop of the screening motor 8, the regulating motor 25 and the rinsing water pump 18.

[0021] During operation, in order to clean the screening plate 5, when the controller detects that the screening plate 5 is blocked, it automatically triggers the backwashing process. The flushing water pump 18 draws water from the water collection tank 17 and delivers it to the flushing rod 22 through the water pumping pipe 19 and the water delivery pipe 20. The regulating motor 25 drives the flushing rod 22 to rotate, so that the flushing water gun 23 sprays high-pressure water jets onto the screening plate 5. The limiting plate 26 ensures that the water gun swings within the set angle range, covering the entire screening plate 5 area and removing the blockage impurities. The flushing wastewater flows into the wastewater tank 15 through the drain hole 10, realizing the recycling of water resources.

[0022] Working principle: In order to treat wastewater from frozen food processing, the wastewater enters the arc-shaped treatment chamber 3 through the feed hopper 2 and flows to the bottom of the chamber under the action of gravity. The screening motor 8 drives the transmission gear 9 and the driven gear 6, which drives the screening shaft 4 to rotate, so that the three screening plates 5 rotate synchronously. When the wastewater flows through the screening plates 5, impurities with a particle size larger than the screen mesh size, such as vegetable leaves, minced meat, and packaging fragments, are intercepted. The wastewater flows into the wastewater chamber 15 through the drain hole 10. When the intercepted impurities rotate with the screening plates 5 to the top of the debris collection chamber 11, they fall into the chamber due to gravity and the pushing action of the screening plates 5. The drain plate 12 causes the water in the debris to drip naturally into the wastewater chamber 15, achieving preliminary solid-liquid separation. The debris is cleaned periodically through the sealing door 13.

[0023] To clean the screening plate 5, when the controller detects that the screening plate 5 is blocked, it automatically triggers the backwashing process. The flushing water pump 18 draws water from the water collection tank 17 and delivers it to the flushing rod 22 through the water pumping pipe 19 and the water delivery pipe 20. The regulating motor 25 drives the flushing rod 22 to rotate, so that the flushing water gun 23 sprays high-pressure water jets onto the screening plate 5. The limiting plate 26 ensures that the water gun swings within the set angle range, covering the entire screening plate 5 area and removing the blockage impurities. The flushing wastewater flows into the wastewater tank 15 through the drain hole 10, realizing the recycling of water resources.
