[0001] This utility model relates to the technical field of landfill leachate treatment, and in particular to a landfill leachate hardening removal device. Background Technology

[0002] Landfill leachate, as a type of high-concentration organic wastewater, is characterized by its complex composition, high concentration of organic matter, high content of heavy metals, and large fluctuations in water quality. How to efficiently treat landfill leachate has always been a challenging scientific problem worldwide. Although traditional direct reinjection technology is simple to operate and inexpensive, it cannot fundamentally solve the pollution problem of landfill leachate.

[0003] Most existing leachate treatment methods involve adjusting the pH of the leachate before introducing it into a reaction tank, and then adding chemical neutralizing agents to the tank to remove hardening from the leachate. However, this process requires a long waiting time and the hardening removal efficiency is low, affecting the overall treatment process. To solve these problems, a leachate hardening removal device is proposed. Utility Model Content

[0028] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0029] Reference Figure 1 and Figure 2 as well as Figure 3As shown, landfill leachate, as a type of high-concentration organic wastewater, is characterized by its complex composition, high organic matter concentration, high heavy metal content, and large fluctuations in water quality. How to efficiently treat landfill leachate has always been a challenging scientific problem worldwide. While traditional direct reinjection technology is simple to operate and low in cost, it cannot fundamentally solve the pollution problem of landfill leachate. Most existing leachate treatment methods involve adjusting the pH of the leachate before introducing it into a reaction tank and adding chemical neutralizing agents to remove hardening agents. However, this process requires a long waiting time and has low hardening efficiency, affecting the overall treatment process. To address these issues, a landfill leachate hardening removal device is proposed, comprising a hardening removal chamber 1, an inlet pipe section 2, an outlet pipe section 3, a mixing pipe 4, a chemical injection base 5, a drive motor 6, a turntable 7, a receiving cavity 8, and a control panel 9. The inlet pipe section 2 is located at the lower left end of the hardening removal chamber 1, and the control panel 9 is installed on the front end of the hardening removal chamber 1. A water outlet pipe section 3 is provided at the upper right end of the hardened housing 1. The water outlet pipe section 3 is sealed to a mixing pipe 4 via a connecting flange. A medicine inlet seat 5 is provided on the upper end of the hardened housing 1. A drive motor 6 is installed inside the medicine inlet seat 5. A turntable 7 is rotatably mounted inside the medicine inlet seat 5. A receiving cavity 8 is opened on the side of the turntable 7. Through the arrangement of the turntable 7, the rotating cavity 53, the receiving cavity 8, and the medicine storage cavity, the drive motor 6 drives the turntable 7 to rotate through the motor shaft 61, and the hardened neutralization inside the medicine storage cavity is achieved. The chemical solution enters the rotating chamber 53 through the inlet 55. When the turntable 7 rotates to the position where the receiving chamber 8 matches the inlet 55, the hardening and neutralizing chemical solution enters the receiving chamber 8. As the turntable 7 continues to rotate, until the receiving chamber 8 matches the position of the discharge port 67, the hardening and neutralizing chemical solution inside the receiving chamber 8 enters the hardening removal box 1 under the action of gravity and mixes with the landfill leachate. This design allows the equipment to continuously treat the landfill leachate for hardening, improving the treatment efficiency and making it highly practical.

[0030] It should be noted that the storage chamber 51 contains a hardening neutralization solution, which can treat landfill leachate for hardening removal. The inlet base 5 has a rotating chamber 53 inside. A door 54 is screwed onto the front end of the rotating chamber 53, facilitating easy opening and maintenance of the interior. A sealing strip 541 is adhered to the side of the door 54, increasing the seal between the door 54 and the rotating chamber 53. The turntable 7 is located inside the rotating chamber 53. The disc 7 can slide tightly along the inner wall of the rotating cavity 53. Three sets of equal-sized receiving cavities 8 are provided on the side of the turntable 7. These cavities 8 are responsible for rotating and transporting the neutralizing and hardening medicine. A motor shaft 61 is mounted on the front end of the drive motor 6. The motor shaft 61 passes through the rotating cavity 53 and connects to the turntable 7. The drive motor 6 can drive the turntable 7 to rotate via the motor shaft 61. A medicine inlet 55 is provided inside the medicine inlet seat 5. The liquid storage cavity 51 is connected to the rotating cavity 53 through the medicine inlet 55. The hardening neutralizing solution inside can enter the rotating chamber 53 through the inlet 55. A guide plate 56 is provided at the bottom of the storage chamber 51, inclined towards the inlet 55, serving a guiding function. A discharge port 67 is provided at the bottom of the inlet base 5. The rotating chamber 53 is connected to the hardening removal chamber 1 through the discharge port 67. The hardening neutralizing solution inside the rotating chamber 53 can enter the hardening removal chamber 1 through the discharge port 67. An installation groove 52 is provided inside the inlet base 5. The drive motor 6 is... The drive motor 6 is placed inside the mounting slot 52. The input end of the drive motor 6 is electrically connected to the output end of the control panel 9 through a wire. The control panel 9 can control the drive motor 6 to turn on. The mixing tube 4 is equipped with a rotating blade 41. The rotating blade 41 can agitate the liquid flowing inside the mixing tube 4. The upper and lower ends of the rotating blade 41 are equipped with a fixed seat 42 of equal size. The fixed seat 42 is connected to the inner wall of the mixing tube 4 through a support rod 43. The fixed seat 42 and the support rod 43 can fix the position of the rotating blade 41.

[0031] Furthermore, the leachate to be treated enters the hardening chamber 1 through the inlet pipe section 2. The operator operates the control panel 9 to turn on the drive motor 6. The drive motor 6 drives the turntable 7 to rotate via the motor shaft 61. The hardening neutralizing agent in the storage chamber enters the rotating chamber 53 through the inlet 55. When the turntable 7 rotates to the position where the receiving chamber 8 matches the inlet 55, the hardening neutralizing agent enters the receiving chamber 8. As the turntable 7 continues to rotate, until the receiving chamber 8 matches the position of the discharge port 67, the hardening neutralizing agent in the receiving chamber 8 enters the discharge port 67 under the action of gravity. The leachate is mixed inside the hardening chamber 1. The empty receiving chamber 8 continues to rotate and circulate. The leachate, after initial mixing with the hardening neutralizing agent, enters the mixing pipe 4 through the drain pipe. When the leachate flows to the position of the rotating blade 41, the leachate forms an axial vortex inside the mixing pipe 4 under the blocking and guiding effect of the rotating blade 41, so that the leachate and the hardening neutralizing agent are mixed more evenly. The user can adjust the automatic dosing cycle and the amount of agent by adjusting the speed of the drive motor 6 or by changing the turntable 7 of different receiving chambers 8.

[0032] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
