Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a powder dispensing device for treating landfill leachate wastewater. Background Technology

[0002] This powder dispensing equipment is designed to accurately, stably, and efficiently add specific powdered agents for landfill leachate treatment into the treatment system to ensure that the effluent quality meets discharge standards or predetermined treatment requirements.

[0003] Existing powder dispensing equipment typically places the powdered chemicals inside a storage tank. When needed, the stored powder is discharged quantitatively through a feeding mechanism to achieve quantitative dispensing. However, due to the harsh environment of the wastewater treatment area, the powder in the storage tank is prone to condensation due to temperature and humidity. When conveying the powder, the dispensing amount is difficult to control due to condensation, resulting in excessive dispensing and affecting the wastewater treatment effect. In view of this, we propose a powder dispensing device for landfill leachate wastewater treatment. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a powder dosing device for landfill leachate treatment, so as to solve the technical problem that the current agent powder has a probability of condensation during storage, which makes it difficult to control the dosage when adding the agent and affects the treatment effect of the effluent.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a powder dispensing device for treating landfill leachate tailwater, comprising a powder dispensing mechanism consisting of a storage tank, a feeding mechanism and a conveying mechanism, wherein a stirring mechanism is installed on the top of the storage tank, a sealing kit rotatably connected to the stirring mechanism is fixedly installed on the top of the storage tank, and a hot air assembly communicating with the sealing kit is fixedly provided on the side of the storage tank.

[0006] The stirring mechanism includes a drive motor, and the output end of the drive motor is fixedly provided with a stirring rod inserted into the storage tank. The stirring rod has a hollow cavity inside, and an air inlet is provided on the rod wall inside the sealing kit. A blower is constructed on the rod wall inside the storage tank that communicates with the hollow cavity, and the lower end of the blower is inclined to the side away from the stirring rod.

[0007] This invention utilizes an air inlet hole on the outer wall of the top of the stirring rod to facilitate the introduction of hot air blown by the hot air assembly into the hollow cavity of the stirring rod through a sealing kit. The hot air is then sprayed into the storage tank through the air pipe, allowing it to be directly injected into the interior of the drug powder. Combined with a drive motor to control the rotation of the stirring rod, the drug powder can be stirred. During the stirring process, the drug powder is dried by hot air treatment, thereby reducing the moisture mixed between the drug powders and keeping them dry. This structural combination reduces the probability of drug powder agglomeration and minimizes the impact on the quantitative dosage of drug powder.

[0008] Preferably, the sealing kit includes a circular column that fits against the outer wall of the stirring rod. The circular column has an air cavity inside, and the diameter of the air cavity is larger than the diameter of the stirring rod. Both sides of the circular column are integrally formed with fixing blocks. One side of the fixing block is flange-connected to the hot air assembly, and the fixing block connected to the hot air assembly has a communicating cavity inside that communicates with the air cavity.

[0009] Preferably, a hollow anti-clogging sleeve is fixedly provided at the lower end of the blower pipe, and a ventilation outlet is provided on the outer wall of the anti-clogging sleeve.

[0010] Preferably, the hot air assembly includes a blower, an electric heater is installed at the air inlet of the blower, and a connecting pipe connected to the fixed block is installed at the air outlet of the blower.

[0011] Preferably, the top of the storage tank is fixedly provided with a positioning screw that penetrates the fixing block on the other side, and the upper end of the positioning screw is threadedly connected with a nut that fits against the top of the fixing block.

[0012] Preferably, the lower end of the positioning screw is fixed with a gasket that fits against the top of the storage tank, and the gasket is made of rubber.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model allows for easy introduction of hot air blown out by the hot air assembly into the hollow cavity of the stirring rod through an air inlet hole on the outer wall of the top of the stirring rod. The hot air is then sprayed into the storage tank through the air blower, directly into the interior of the drug powder. Combined with the drive motor controlling the rotation of the stirring rod, the drug powder can be stirred. During the stirring process, the drug powder is dried by hot air treatment, thereby reducing the moisture mixed between the drug powders and keeping them dry. This structure reduces the probability of drug powder agglomeration and minimizes the impact on the quantitative dosage of drug powder.

[0015] 2. This utility model also increases the air outlet diameter by setting a hollow anti-clogging sleeve at the lower end of the blower pipe. This structural design can reduce the probability of port blockage when the blower pipe is inserted into the medicine powder, thereby improving the air outlet effect of the blower pipe. Combined with the design of the air outlet hole, it facilitates air outlet. At the same time, during the rotation of the stirring rod, the medicine powder can be thrown out from the inside of the anti-clogging sleeve through the position of the air outlet hole, further improving the dehumidification effect of the medicine powder.

[0022] like Figures 1 to 5 As shown, this utility model relates to a powder dispensing device for treating landfill leachate tailwater, comprising a powder dispensing mechanism consisting of a storage tank 1, a feeding mechanism 2, and a conveying mechanism 3. A stirring mechanism 4 is installed on the top of the storage tank 1, and a sealing kit 5 rotatably connected to the stirring mechanism 4 is fixedly installed on the top of the storage tank 1. A hot air assembly 6 communicating with the sealing kit 5 is fixedly installed on the side of the storage tank 1. The feeding mechanism 2 and the conveying mechanism 3 achieve the loading and unloading of materials by rotating a spiral blade. This structural combination can improve the accuracy of loading and unloading. The stirring mechanism 4 is designed to stir the powder inside the storage tank 1. With the connection between the sealing kit 5 and the hot air assembly 6, the powder can be dried by hot air while stirring, maintaining the dryness of the powder.

[0023] The stirring mechanism 4 includes a drive motor 401. The output end of the drive motor 401 is fixedly provided with a stirring rod 402 inserted into the storage tank 1. The stirring rod 402 has a hollow cavity inside. An air inlet 403 is opened on the rod wall inside the sealing kit 5. A blower pipe 404 communicating with the hollow cavity is constructed on the rod wall inside the storage tank 1. The lower end of the blower pipe 404 is inclined away from the side of the stirring rod 402. The drive motor 401 can control the rotation of the stirring rod 402, so that the stirring blades on the outer wall of the stirring rod 402 can stir the medicine powder. The communication between the air inlet 403 and the hollow cavity can facilitate the entry of hot air, which is then blown out along the position of the blower pipe 404, thereby achieving the operation of drying the medicine powder.

[0024] In an embodiment of this utility model, the sealing kit 5 includes a circular column 501 that fits against the outer wall of the stirring rod 402. An air cavity 502 is formed inside the circular column 501, and the diameter of the air cavity 502 is larger than the diameter of the stirring rod 402. Fixing blocks 503 are integrally formed on both sides of the circular column 501. One fixing block 503 is flange-connected to the hot air assembly 6, and the fixing block 503 connected to the hot air assembly 6 has a communicating cavity 504 that communicates with the air cavity 502. The communication between the air cavity 502 inside the circular column 501 and the communicating cavity 504 inside the fixing block 503 facilitates the contact of hot air blown out by the hot air assembly 6 with the stirring rod 402. This allows the hot air to enter the interior of the stirring rod 402 through the air inlet 403, achieving a ventilation effect.

[0025] In an embodiment of this utility model, a hollow anti-clogging sleeve 405 is fixedly provided at the lower end of the blower pipe 404, and a ventilation outlet 406 is provided on the outer wall of the anti-clogging sleeve 405. By adding the anti-clogging sleeve 405 structure to the bottom of the blower pipe 404, the diameter of the lower end of the blower pipe 404 can be enlarged, thereby reducing the situation of the medicine powder clogging the lower end of the blower pipe 404 and improving the ventilation effect. At the same time, the rotation range can be expanded during the rotation of the stirring rod 402, and the air outlet 406 can further enhance the air blowing range.

[0026] In an embodiment of this utility model, the hot air assembly 6 includes a blower 601, an electric heater 602 is installed at the air inlet of the blower 601, and a connecting pipe 603 connected to the fixing block 503 is installed at the air outlet of the blower 601; the air heated by the electric heater 602 is sent into the interior of the sealing kit 5 through the connecting pipe 603 by the blower 601, which can achieve the effect of hot air blowing.

[0027] In an embodiment of this utility model, a positioning screw 101 is fixedly provided on the top of the storage tank 1, which passes through the fixing block 503 on the other side. The upper end of the positioning screw 101 is threadedly connected to a nut 103 that fits against the top of the fixing block 503. The position of the sealing kit 5 can be fixed by the cooperation of the positioning screw 101 and the nut 103, which facilitates disassembly and assembly.

[0028] In an embodiment of this utility model, a gasket 102 is fixedly provided at the lower end of the positioning screw 101 and fits against the top of the storage tank 1, and the gasket 102 is made of rubber; the gasket 102 has a certain buffering effect and can play a certain shock absorption effect during the operation of the stirring mechanism 4.

[0029] Working Principle: This embodiment provides a powder dispensing device for landfill leachate tailwater treatment. Firstly, the feeding mechanism 2 introduces the powdered agent into the storage tank 1, achieving the effect of adding the agent. The feeding mechanism 3 at the bottom of the storage tank 1 discharges the powdered agent from inside the storage tank 1, thus quantitatively dispensing the powdered agent into the tailwater treatment tank. During tailwater treatment or in a shutdown state, the hot air assembly 6 can be periodically activated. The blower 601 operates to send air heated by the heater 602 into the sealed assembly 5, and then through the air inlet 40... Position 3 enters the hollow cavity of the stirring rod 402. During continuous air supply, it can be sent into the interior of the storage tank 1 through the connected air pipe 404, thereby contacting the drug powder inside. The hot air can dry the moisture absorbed by the drug powder, thus maintaining the dryness of the drug powder inside the storage tank 1. The rotation of the stirring rod 402 can stir the drug powder during the ventilation and drying process, improving the uniformity of ventilation and drying. This structure can reduce the condensation of drug powder inside the storage tank 1 and maintain the accuracy of drug powder dispensing.
