[0002] Wastewater treatment equipment is a device that purifies wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment equipment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly being used in some small watershed areas.

[0003] Existing small watershed sewage treatment devices typically require manual addition of chemicals to induce sedimentation of impurities within the sewage, thereby purifying it. However, manual addition of chemicals can easily lead to errors, resulting in excessive amounts. This not only causes waste but also leaves some chemicals in the sewage, causing secondary pollution. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a sewage discharge treatment device for small watersheds, which solves the problem that existing sewage discharge treatment devices for small watersheds are prone to errors when adding chemicals manually, resulting in the addition of excessive chemicals. This not only easily leads to waste, but also easily causes some chemicals to remain in the sewage, causing secondary pollution to the sewage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sewage discharge treatment device for a small watershed, comprising a base plate, a filter box fixedly connected to the top of the base plate, a sedimentation tank fixedly connected to the top of the base plate, a connecting plate fixedly connected between the filter box and the sedimentation tank, a water pump fixedly connected to the top of the connecting plate, an inlet pipe fixedly connected to one side of the water pump, a filter cylinder fixedly connected to the bottom end of the inlet pipe, the filter cylinder having several filter holes, an outlet pipe fixedly connected to the top of the water pump, a sewage inlet pipe fixedly connected to one side of the filter box, and a discharge pipe fixedly connected to one side of the sedimentation tank;

[0006] Two fixing plates are fixedly connected to the top of the sedimentation tank, and a reagent cylinder is fixedly connected to the two fixing plates. A feed pipe is fixedly connected to the top of the reagent cylinder, and a sealing plug is threaded to the top of the feed pipe. An inclined pipe is connected to one side of the reagent cylinder, and an L-shaped pipe is connected to one end of the inclined pipe. A circular frame is fixedly connected to one side of the reagent cylinder. A piston is installed inside the reagent cylinder. A connecting rod is fixedly connected to one side of the piston, and a push plate is fixedly connected to one side of the connecting rod. A spring is sleeved on the connecting rod.

[0007] As a further embodiment of this utility model: the filter cylinder, the inlet pipe, the water pump and the outlet pipe are connected, the outlet pipe is fixed to the sedimentation tank, and one end of the outlet pipe extends into the interior of the sedimentation tank.

[0008] As a further embodiment of this utility model: the push plate has an arc surface design, the top of the sealing plug is fixedly connected to a knob, and the water inlet pipe is fixed to the filter box.

[0009] As a further embodiment of this utility model: one end of the spring is fixedly connected to the push plate, and the other end of the spring is fixedly connected to the circular frame.

[0010] As a further embodiment of this utility model: the filter cylinder is located inside the filter box, and the bottom end of the L-shaped tube extends into the sedimentation tank.

[0011] As a further embodiment of this utility model: the L-shaped tube is fixed to the inclined tube, the L-shaped tube is fixed to the sedimentation tank, and the inclined tube is fixed to the reagent cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The sewage treatment device for this small watershed is equipped with a spring, piston, inclined pipe, connecting rod and push plate. Pushing the push plate moves the connecting rod and piston to the left, while the spring exerts a counterforce on the push plate. The piston squeezes the agent in the agent cylinder, allowing the agent to enter the sedimentation tank through the inclined pipe and L-shaped pipe. After a period of time, the sewage in the sedimentation tank will settle. The spring exerts a counterforce on the push plate, which can buffer the movement of the push plate, avoid excessive force by personnel pushing the push plate and adding too much agent, avoid waste, and prevent some agent residue in the sewage from causing secondary pollution.

[0014] 2. The wastewater treatment device for this small watershed is equipped with an inlet pipe, a sealing plug, and a knob. When it is necessary to add chemicals to the chemical cylinder, first squeeze the knob to unscrew the sealing plug. Then, chemicals can be added to the chemical cylinder through the inlet pipe. After the chemicals are added, squeeze the knob to tighten the sealing plug to seal the chemical cylinder. The inlet pipe facilitates the replenishment of chemicals to the chemical cylinder, and the sealing plug ensures the airtightness of the chemical cylinder and the normal operation of the piston.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a sewage discharge treatment device for a small watershed, including a base plate 1, a filter box 2 fixedly connected to the top of the base plate 1, a sedimentation tank 3 fixedly connected to the top of the base plate 1, a connecting plate 6 fixedly connected between the filter box 2 and the sedimentation tank 3, a water pump 7 fixedly connected to the top of the connecting plate 6, an inlet pipe 11 fixedly connected to one side of the water pump 7, a filter cylinder 12 fixedly connected to the bottom end of the inlet pipe 11, the filter cylinder 12, the inlet pipe 11, the water pump 7 and the outlet pipe 10 are connected, the outlet pipe 10 is fixed to the sedimentation tank 3, and one end of the outlet pipe 10 extends into the interior of the sedimentation tank 3.

[0022] The filter cylinder 12 has several filter holes 13. Because of the filter holes 13, large-volume impurities are filtered through the filter holes 13 to prevent impurities from entering the water pump 7 and causing damage to the water pump 7. It also facilitates the removal of large-volume impurities from the sewage. The filter cylinder 12 is located inside the filter box 2. The bottom end of the L-shaped tube 15 extends into the sedimentation tank 3. The top of the water pump 7 is fixedly connected to the water outlet pipe 10. The filter box 2 is fixedly connected to the sewage inlet pipe 4 on one side. The sedimentation tank 3 is fixedly connected to the discharge pipe 5 on one side. The top of the sedimentation tank 3 is fixedly connected to two fixed plates 8. The two fixed plates 8 are fixedly connected to the chemical cylinder 9. The top of the chemical cylinder 9 is fixedly connected to the feed pipe 16.

[0023] A sealing plug 22 is threaded to the top of the feed pipe 16. An inclined pipe 14 is connected to one side of the reagent cylinder 9. Because of the inclined pipe 14, when the reagent is added into the reagent cylinder 9 through the feed pipe 16, the inclined pipe 14 blocks the reagent and prevents the reagent from flowing out through the L-shaped pipe 15. This allows the reagent cylinder 9 to store the reagent, which facilitates the smooth progress of subsequent work. One end of the inclined pipe 14 is connected to the L-shaped pipe 15. The L-shaped pipe 15 is fixed to the inclined pipe 14. The L-shaped pipe 15 is fixed to the sedimentation tank 3. The inclined pipe 14 is fixed to the reagent cylinder 9. A circular frame 18 is fixedly connected to one side of the reagent cylinder 9. A piston 17 is installed inside the reagent cylinder 9.

[0024] A connecting rod 20 is fixedly connected to one side of the piston 17. Because of the connecting rod 20, when the push plate 21 moves to the left, it will compress the spring 19. The connecting rod 20 will restrict the spring 19 to prevent it from bending excessively and deforming, thus ensuring the normal use of the spring 19. A push plate 21 is fixedly connected to one side of the connecting rod 20. The push plate 21 has an arc surface design. A knob 23 is fixedly connected to the top of the sealing plug 22. Because of the knob 23, the sealing plug 22 can be turned more easily by pinching the knob 23, thereby improving the ease of operation. The water inlet pipe 11 is fixed to the filter box 2. A spring 19 is sleeved on the connecting rod 20. One end of the spring 19 is fixedly connected to the push plate 21, and the other end of the spring 19 is fixedly connected to the circular frame 18.

[0025] The working principle of this utility model is as follows:

[0026] In use, wastewater is discharged into the filter box 2 through the inlet pipe 4. At this time, the water pump 7 is started, and the water pump 7 draws the wastewater in through the inlet pipe 11. At the same time, the filter holes 13 will filter out some large-volume impurities in the wastewater. The wastewater in the inlet pipe 11 passes through the water pump 7 and the outlet pipe 10 and finally enters the sedimentation tank 3. At this time, the push plate 21 is pushed to move the connecting rod 20 and the piston 17 to the left. At the same time, the spring 19 exerts a reverse force on the push plate 21. The piston 17 squeezes the agent in the agent cylinder 9, so that the agent enters the sedimentation tank 3 through the inclined pipe 14 and the L-shaped pipe 15. After a period of time, the wastewater in the sedimentation tank 3 will settle. At this time, the treated wastewater is discharged through the discharge pipe 5.

[0027] When it is necessary to add medicine into the medicine cylinder 9, first squeeze the knob 23 to unscrew the sealing plug 22. At this time, medicine can be added into the medicine cylinder 9 through the feed pipe 16. After the medicine is added, squeeze the knob 23 to tighten the sealing plug 22 to seal the medicine cylinder 9.
