Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a small wastewater treatment device. Background Technology

[0002] Kitchen wastewater treatment is a common problem in daily life, especially during the use of dishwashing sinks. Kitchen wastewater usually contains a large amount of kitchen waste, such as food scraps, grease, vegetable leaves, and other impurities.

[0003] To trap these impurities, many households install strainer screens at the drain outlet of their sinks. These screens effectively block most kitchen waste, preventing it from flowing directly into the drainpipe and reducing the risk of blockages. However, this method has significant drawbacks.

[0004] First, the filter tray needs to be manually cleaned regularly, which not only increases the housework burden for family members, but may also lead to an unpleasant experience, especially when dealing with greasy and rotten food scraps;

[0005] Secondly, during manual cleaning, some kitchen waste may flow back into the drain pipe through the water flow or gaps in the filter screen, causing blockage inside the pipe. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] In view of the problems existing in the prior art, the present invention provides a small-scale sewage treatment device to solve the technical problem mentioned in the background art of poor convenience in the treatment of kitchen wastewater.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A small-scale wastewater treatment device includes a treatment tank with a feed inlet at the top. An arc-shaped filter screen is installed inside the treatment tank, and a pulverizing shaft with pulverizing blades is positioned above the arc-shaped filter screen. The pulverizing shaft is mounted on the treatment tank via bearings, and a motor is connected to its outer end for transmission. A spray pipe is installed on the inner wall of the treatment tank above the pulverizing blades, with multiple spray heads evenly distributed on the spray pipe. A liquid inlet pipe extends from the spray pipe to the outside of the treatment tank and is connected to the liquid supply assembly. An anti-odor structure is installed above the spray pipe. A flow guide hood is installed at the bottom of the treatment tank, and a discharge pipe is installed at the bottom of the flow guide hood.

[0011] The present invention is further configured such that the anti-odor structure includes a fixed plate, the fixed plate is disposed on one side inside the treatment box, and a flip plate is sealed and fitted on one side of the fixed plate. The side of the flip plate away from the fixed plate is elastically hinged to the inner wall of the treatment box. The flip plate facilitates the downward flow of sewage containing impurities. At the same time, after the sewage flow is completed, it can automatically spring back and seal, preventing the odor inside the treatment box from being transmitted upwards in the reverse direction.

[0012] The present invention is further configured such that an installation shaft is provided on the inner wall of the processing box, and a rotating frame is provided at the bottom of the flip plate. The rotating frame is rotatably mounted on the installation shaft via a bearing, and a torsion spring is mounted on the installation shaft. One end of the torsion spring presses against the bottom of the flip plate, and the other end presses against the inner wall of the processing box. The elastic rotational hinge between the flip plate and the processing box is achieved through the cooperation of the installation shaft, the rotating frame, and the torsion spring.

[0013] The present invention is further configured such that the processing box has an installation port, the arc-shaped filter screen extends outward through the installation port and has a connecting section, the outer end of the connecting section is provided with a sealing baffle, the sealing baffle can seal and block the installation port, so as to realize the detachable installation of the arc-shaped filter screen in the processing box.

[0014] The present invention is further configured such that a locking buckle is provided between the sealing baffle and the outer wall of the treatment box, and a sealing gasket is provided on the inner side of the sealing baffle to fit the installation port. The locking buckle enables quick locking and fixing between the sealing baffle and the treatment box, thereby facilitating the quick installation and removal of the arc-shaped filter on the treatment box, and making it easy to remove the arc-shaped filter from the installation port for separate cleaning. The sealing gasket is used to enhance the sealing performance of the connection between the sealing baffle and the sealing port.

[0015] The present invention is further configured such that the liquid supply component includes a liquid storage tank, a pump body is connected to the liquid storage tank, and a liquid supply hose is provided between the output end of the pump body and the liquid inlet pipe. When the pump body is started, the deodorizing decomposition liquid in the liquid storage tank can be extracted and transported to the liquid inlet pipe through the liquid supply hose, and then transported to the spray pipe through the liquid inlet pipe. The liquid is then sprayed evenly in the treatment box through the spray head on the spray pipe, thereby deodorizing the inside of the treatment box and chemically decomposing residual impurities, thus improving the cleanliness of the inside of the treatment box.

[0016] The present invention is further configured such that the liquid storage tank is provided with a liquid inlet and a sealing cap is provided at the liquid inlet, so that liquid can be replenished into the liquid storage tank through the liquid inlet and the sealing cap is used to seal the liquid inlet.

[0017] The present invention is further configured such that mounting slides are provided on both sides of the arc-shaped filter screen, and mounting grooves are provided inwardly through the mounting opening. The mounting slides slide within the mounting grooves. When the arc-shaped filter screen is installed, the mounting sliders on the side of the arc-shaped filter screen can slide within the mounting grooves and be pushed inward through the mounting opening, thereby achieving stable installation between the arc-shaped filter screen and the treatment box, and ensuring a sealed fit between the inner ends of the arc-shaped filter screen.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a small-scale sewage treatment device, which has the following features:

[0020] Beneficial effects:

[0021] 1. This utility model, by setting an arc-shaped filter screen, can be used in conjunction with a crushing shaft and crushing blades. During use, domestic wastewater carrying debris enters the treatment tank through the feed inlet. During this process, the motor is started, and the motor controls the crushing shaft to rotate. The crushing shaft drives the crushing blades to rotate, and the crushing blades can crush the kitchen waste debris intercepted on the arc-shaped filter screen so that the debris can be discharged downward through the arc-shaped filter screen. This can avoid the debris clogging the pipes and improve the smoothness of kitchen wastewater discharge.

[0022] 2. This utility model has a spray pipe installed on the processing box above the crushing blade. When in use, the pump can be started, and the deodorizing and decomposing liquid in the storage tank can be extracted by the pump and transported to the inlet pipe through the liquid supply hose. The liquid is then transported to the spray pipe and sprayed evenly in the processing box through the spray head on the spray pipe. This can deodorize the inside of the processing box and chemically decompose the residual impurities, thereby improving the cleanliness of the inside of the processing box.

[0023] 3. Simultaneously, this utility model features an anti-odor-backflow structure above the spray pipe. This structure includes a fixed plate and a flipping plate that cooperate with each other. When kitchen wastewater containing impurities enters the treatment tank through the inlet, the wastewater's own weight forces the flipping plate to flip, causing it to flip against the torsion spring. This allows the flipping plate to separate from the fixed plate, allowing the wastewater containing impurities to fall through the gap formed by the separation into the treatment tank for drainage and impurity treatment. After the water flow is complete, the torsion spring's elasticity drives the flipping plate to rotate and seal against the fixed plate, thus preventing odors from the treatment tank from backflowing upwards and improving performance.

[0024] 4. This utility model can automatically intercept and crush impurities in sewage, avoiding pipe blockage. At the same time, it can remove odors and decompose residues, and prevent odor backflow. Attached Figure Description

[0042] In summary:

[0043] In use, this utility model allows domestic wastewater carrying impurities to enter the treatment tank 1 through the feed inlet 2. When kitchen wastewater containing impurities enters the treatment tank 1 through the feed inlet 2, it can squeeze the flip plate 13 under its own gravity. The flip plate 13, in cooperation with the rotating frame 15 and the mounting shaft 14, squeezes the torsion spring 16 to flip, so that the flip plate 13 can be separated from the fixed plate 12. This allows the wastewater containing impurities to fall down into the treatment tank 1 through the gap formed by the separation of the fixed plate 12 and the flip plate 13 for drainage and impurity treatment.

[0044] Meanwhile, after the water flow is completed, the flip plate 13 will be driven to rotate under the action of the torsion spring 16, and will be sealed and fitted with the fixed plate 12, thereby preventing the odor inside the treatment box 1 from being transmitted back to the top of the treatment box 1 and improving the performance.

[0045] Wastewater falling into the treatment tank 1 can pass through the arc-shaped filter screen 3 and be discharged downwards through the discharge pipe 11. Impurities will be intercepted on the arc-shaped filter screen 3. During this process, the motor 6 is started, and the motor 6 controls the rotation of the crushing shaft 4. The crushing shaft 4 drives the crushing blades 5 to rotate. The crushing blades 5 can crush the kitchen waste impurities intercepted on the arc-shaped filter screen 3 so that the impurities can be discharged downwards through the arc-shaped filter screen 3. This can avoid the situation of large pieces of impurities clogging the pipes and improve the smoothness of kitchen wastewater discharge.

[0046] This invention features a spray pipe 7 installed on the processing box 1 above the shredder blade 5. During use, the pump can be activated to extract the deodorizing and decomposing liquid from the storage tank 22 and deliver it through the supply hose 23 to the inlet pipe 9. The liquid is then delivered to the spray pipe 7, where it is evenly sprayed through the spray nozzles 8 on the spray pipe 7 into the processing box 1. This deodorizes the interior of the processing box 1 and chemically decomposes residual impurities, improving the cleanliness of the processing box 1. The product used for deodorizing and decomposing kitchen waste is an existing product; this invention will not provide a specific description, but rather select a product that meets the specific needs.
