Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to an organic wastewater treatment device. Background Technology

[0002] Domestic sewage, food processing, and industrial wastewater such as papermaking contain organic substances such as carbohydrates, proteins, oils, and lignin. These substances exist in the sewage in a suspended or dissolved state and can be decomposed by the biochemical action of microorganisms. The decomposition process requires oxygen and is therefore called oxygen-consuming pollutants. Such pollutants can reduce dissolved oxygen in the water and affect the growth of fish and other aquatic organisms.

[0003] Furthermore, this wastewater contains large amounts of organic matter such as carbohydrates, fats, proteins, and cellulose, exhibiting complex composition, high color, and unpleasant odor, severely polluting the aquatic environment. Therefore, effective treatment of organic wastewater is of paramount importance for protecting the aquatic environment.

[0004] When the existing equipment filters and removes impurities from organic wastewater, the inlet remains in a continuous water intake state when the filter screen is clogged. The filter screen cannot perform its filtering function, which may result in the wastewater being discharged directly without being filtered or with incomplete filtration, causing pollution to the surrounding environment. Therefore, improvements are needed. Summary of the Invention

[0005] The main objective of this invention is to provide an organic wastewater treatment device that, when the fine filter plate is clogged, has a blocking block that moves upward to block the inlet, preventing the inlet from being constantly filled with water. At the same time, it moves the wedge-shaped pressing rod upward to release the pressure on the fine filter plate. Under the action of the spring force, it pushes the locking rod and the locking hole to separate, facilitating the disassembly of the upper and lower treatment boxes and the cleaning of the fine filter plate, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] An organic wastewater treatment device includes an upper treatment tank and a lower treatment tank. The upper treatment tank, which has an inlet at the top, is detachably installed on the top of the lower treatment tank. A drain outlet is provided on one side of the lower end of the lower treatment tank wall. A support ring is fixedly installed inside the lower treatment tank above the drain outlet. A fine filter plate is placed on the support ring. A triggering component is provided on the outer wall of the upper treatment tank. The triggering component consists of a float block with a transmission rod and a squeezing block fixed on the outer surface installed inside a connecting pipe. A forward and reverse motor is installed on the surface of the upper treatment tank above the triggering component.

[0008] A trigger switch is installed on the lower shell of the reversible motor, located directly above the trigger assembly. The output end of the reversible motor is connected to a bidirectional screw that rotates between the inner walls of the upper processing box. The bidirectional screw is threaded with two sets of movable sleeves. The upper surfaces of the two sets of movable sleeves are hinged to the sealing blocks of the sealing assembly with connecting rods. The sealing assembly is composed of a coarse filter plate that slides inside the upper processing box and a sealing block installed in the direction of the bidirectional screw.

[0009] The bottom of the sealing block is provided with a pressing component for pressing and fixing the fine filter plate, and the pressing component is composed of a U-shaped rod connected to a wedge-shaped pressing rod through an inverted T-shaped rod;

[0010] A through hole for sliding insertion of a locking rod is provided on the inner wall of the lower processing box above the fine filter plate, and a locking hole for insertion of the locking rod is provided on the inner wall of the upper processing box outside the through hole. A wedge-shaped block that matches the inclined surface of the wedge-shaped pressing rod is fixed to the end of the locking rod away from the lower processing box, and a spring is sleeved on the rod body of the locking rod.

[0011] Furthermore, the top opening of the upper treatment box is detachably fitted with a top cover by screws, and a water inlet is centrally located on the top surface of the top cover.

[0012] Furthermore, the connecting pipe is fixed to the surface of the upper processing box below the forward and reverse motor, and the lower opening of the connecting pipe is connected to the upper processing box. A float is slidably arranged inside the connecting pipe, and a transmission rod extending upward through the upper opening of the connecting pipe is fixedly installed on the surface of the float. A pressing block is fixed to the top end of the transmission rod protruding from the connecting pipe.

[0013] Furthermore, a coarse filter plate is slidably disposed on the inner wall of the upper treatment box above the bidirectional screw, and a slot is provided in the center of the surface of the coarse filter plate. A sealing block located below the water inlet is fixedly installed in the slot of the coarse filter plate, and the lower surface of the sealing block is hinged to the connecting rod.

[0014] Furthermore, a U-shaped rod is installed on the lower surface of the sealing block between the connecting rods, through which a bidirectional screw passes, and an inverted T-shaped rod is fixedly installed at the bottom end of the U-shaped rod below the bidirectional screw. Both ends of the lower rod of the inverted T-shaped rod are fixed with wedge-shaped pressing rods that contact the fine filter plate.

[0015] Furthermore, the upper and lower processing boxes are provided with matching placement slots on opposite sides, and the placement slot of the upper processing box is fitted and locked outside the placement slot of the lower processing box.

[0016] Furthermore, a guide rod is fixedly connected to the inner wall surface of the lower processing box between the fine filter plate and the locking rod, and a limit ring is fixedly connected to the end of the guide rod away from the inner wall surface of the lower processing box. A guide sleeve fixed to the lower block surface of the wedge block is slidably sleeved on the guide rod surface on one side of the limit ring.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. Through the setting of connecting pipe, float, transmission rod and squeezing block, when the surface of the fine filter plate is blocked and cannot achieve the filtering effect, or when the discharge rate of the drain outlet is less than the inlet rate of the inlet, sewage will accumulate above the fine filter plate. When the sewage in the lower treatment tank overflows the fine filter plate, the sewage will enter the connecting pipe. Under the action of water buoyancy, the float pushes the transmission rod to move upward, so that the squeezing block will press the trigger switch on the forward and reverse motor, so that the forward and reverse motor will start.

[0019] Second, by setting up a forward and reverse motor, a bidirectional screw, a movable sleeve, a connecting rod, a sealing block, and a coarse filter plate, when the forward and reverse motor is started by the trigger component, the forward and reverse motor drives the bidirectional screw to rotate. The two movable sleeves move closer to each other on the bidirectional screw. Under the action of the connecting rod, they push the sealing block to move upward, thus sealing the inlet and avoiding the ineffective operation of the wastewater treatment device inlet being in a water-in-flow state when there is blockage or low drainage efficiency.

[0020] 3. Through the setting of locking rod, locking hole, spring, wedge block, guide rod, guide sleeve and limiting ring, when the blocking block moves upward, it will drive the U-shaped rod and the inverted T-shaped rod to move upward, which will drive the wedge pressing rod to move upward, releasing the pressure on the fine filter plate. At the same time, under the action of spring force, the locking rod is pushed to separate from the through hole and the locking hole, which facilitates the disassembly of the upper and lower processing boxes and the cleaning of the fine filter plate.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1 to 4 The present invention provides a technical solution: an organic wastewater treatment device, including an upper treatment tank 1 and a lower treatment tank 2. The upper treatment tank 1 with a water inlet at the top is detachably installed on the top of the lower treatment tank 2. A drain outlet is provided on one side of the lower end of the tank wall of the lower treatment tank 2. A support ring 3 is fixedly installed inside the lower treatment tank 2 above the drain outlet. A fine filter plate 4 is placed on the support ring 3. A triggering component is provided on the outer wall of the upper treatment tank 1. The triggering component is composed of a float 11 with a transmission rod 12 and a squeezing block 13 fixed on the outer surface installed inside the connecting pipe 10. A forward and reverse motor 5 is installed on the surface of the upper treatment tank 1 above the triggering component.

[0028] A trigger switch 25 is installed on the lower shell of the forward and reverse motor 5, located directly above the trigger assembly. The output end of the forward and reverse motor 5 is connected to a bidirectional screw 6 that rotates between the inner walls of the upper processing box 1. A double set of movable sleeves 7 are threaded onto the bidirectional screw 6. A connecting rod 8 is hinged between the upper surface of the double set of sleeves 7 and the sealing block 15 of the sealing assembly. The sealing assembly is composed of a coarse filter plate 14 that slides inside the upper processing box 1 and a sealing block 15 installed in the direction of the bidirectional screw 6.

[0029] The bottom of the sealing block 15 is provided with a pressing component for pressing and fixing the fine filter plate 4. The pressing component is composed of a U-shaped rod 16 connected to a wedge-shaped pressing rod 18 through an inverted T-shaped rod 17.

[0030] A through hole is provided on the inner wall of the lower treatment box 2 above the fine filter plate 4 for sliding insertion of the locking rod 19. A locking hole is provided on the inner wall of the upper treatment box 1 outside the through hole for insertion of the locking rod 19. A wedge block 20 is fixed at the end of the rod 19 away from the lower treatment box 2, which is adapted to the upper inclined surface of the wedge pressing rod 18. A spring 21 is sleeved on the rod body of the locking rod 19.

[0031] The top opening of the upper treatment box 1 is detachably fitted with a top cover 9 by screws, and a water inlet is centrally located on the top surface of the top cover 9. The detachable design of the top cover 9 facilitates the subsequent opening of the upper treatment box 1 to clean the coarse filter plate 14.

[0032] The connecting pipe 10 is fixed to the surface of the upper processing box 1 below the forward and reverse motor 5. The lower opening of the connecting pipe 10 is connected to the upper processing box 1. A float 11 is slidably installed inside the connecting pipe 10. A transmission rod 12 is fixedly installed on the surface of the float 11, extending upward through the upper opening of the connecting pipe 10. A compression block 13 is fixed to the top of the transmission rod 12 that protrudes from the connecting pipe 10. The float 11 is made of foam material. Foam material has a large buoyancy in water, which makes it easy to push the compression block 13 upward.

[0033] Among them, a coarse filter plate 14 is slidably installed on the inner wall of the upper treatment box 1 above the bidirectional screw 6. A groove is opened in the center of the surface of the coarse filter plate 14. A sealing block 15 located below the water inlet is fixedly installed in the groove of the coarse filter plate 14. The lower surface of the sealing block 15 is hinged to the connecting rod 8.

[0034] Among them, a U-shaped rod 16 is installed on the lower surface of the sealing block 15 between the connecting rods 8 and passed through by the bidirectional screw 6. An inverted T-shaped rod 17 is fixedly installed at the bottom end of the U-shaped rod 16 below the bidirectional screw 6. Both ends of the lower rod of the inverted T-shaped rod 17 are fixed with wedge-shaped pressing rods 18 that contact the fine filter plate 4.

[0035] The upper processing box 1 and the lower processing box 2 are provided with matching placement slots on opposite sides, and the placement slot of the upper processing box 1 is fitted and locked outside the placement slot of the lower processing box 2.

[0036] Among them, a guide rod 22 is fixedly connected to the inner wall surface of the lower treatment box 2 between the fine filter plate 4 and the locking rod 19. A limit ring 24 is fixedly connected to the end of the guide rod 22 away from the inner wall surface of the lower treatment box 2. A guide sleeve 23 fixed to the lower block surface of the wedge block 20 is slidably sleeved on the surface of the guide rod 22 on one side of the limit ring 24.

[0037] It should be noted that the present invention is an organic wastewater treatment device, which is detachably installed by means of an upper treatment tank 1 and a lower treatment tank 2. The top opening of the upper treatment tank 1 is detachably provided with a top cover 9 with a water inlet. After the top cover 9 is removed, the top opening of the upper treatment tank 1 can be exposed to facilitate subsequent cleaning of the coarse filter plate 14. The drain outlet at the lower treatment tank 2 can drain water. When the organic wastewater is filtered and impurities are removed, it can enter the upper treatment tank 1 through the water inlet and be initially filtered by the coarse filter plate 14. The organic wastewater after the initial filtration can continue to fall into the lower treatment tank 2 and be filtered by the fine filter plate 4. The wastewater after being filtered by the fine filter plate 4 is discharged from the drain outlet of the lower treatment tank 2 for subsequent discharge.

[0038] When the fine filter plate 4 is in normal filtration state, the wedge-shaped pressing rod 18 can press the fine filter plate 4 downward. With the cooperation of the support ring 3, the fine filter plate 4 can be positioned and fixed. When the fine filter plate 4 is in normal filtration state, the wedge-shaped pressing rod 18 will also overcome the elastic force of the spring 21 when pressing the fine filter plate 4, and push the wedge block 20 to move, so that the locking rod 19 can be inserted into the through hole of the lower processing box 2 and the locking hole of the upper processing box 1, thereby locking the upper processing box and the lower processing box.

[0039] When the surface of the fine filter plate 4 is blocked and cannot achieve the filtering effect, or when the discharge rate of the drain outlet is less than the inlet rate of the inlet, the sewage will accumulate above the fine filter plate 4. When the sewage in the lower treatment tank 2 overflows the fine filter plate 4, the sewage will enter the connecting pipe 10. Under the action of water buoyancy, the float 11 pushes the transmission rod 12 to move upward, so that the squeezing block 13 will press the trigger switch 25 on the forward and reverse motor 5. The trigger switch 25 is used to control the forward and reverse motor 5 to start after power is connected.

[0040] When the forward and reverse motor 5 is started by the triggering component through the trigger switch 25, the forward and reverse motor 5 drives the bidirectional screw 6 to rotate. Since the bidirectional screw 6 is threadedly connected to the movable sleeve 7, and the coarse filter plate 14 restricts the rotation of the movable sleeve 7 through the sealing block 15 and the connecting rod 8, the two movable sleeves 7 move closer to each other on the bidirectional screw 6. At this time, under the action of the movable sleeve 7, the connecting rod 8 will push the sealing block 15 to move the coarse filter plate 14 upward, so that the sealing block 15 blocks the water inlet upward, avoiding the water inlet from being in the water intake state when the filter plate in the wastewater treatment device is blocked or the drainage efficiency is low, thus avoiding the wastewater treatment device that cannot achieve the filtration effect from working continuously without any effect.

[0041] When the blocking block 15 moves upward to block the inlet, it will drive the U-shaped rod 16 and the inverted T-shaped rod 17 to move upward, which will drive the wedge-shaped pressing rod 18 to move upward, releasing the pressure on the fine filter plate 4. At the same time, under the action of the spring 21, the locking rod 19 is pushed to separate from the locking hole, making it convenient to disassemble the locking bolts of the upper treatment box 1 and the lower treatment box 2 and clean the fine filter plate 4. The guide rod 22 is fixedly connected to the inner wall of the lower treatment box 2, so that the wedge block 20 can slide under the restriction of the guide sleeve 23 and the limiting ring 24 at the end of the guide rod 22.

[0042] It should be noted that the present invention is an organic wastewater treatment device. All components in the present invention are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
