Description

Technical Field

[0001] This utility model relates to the field of chemical phosphorus removal technology, specifically to a chemical phosphorus removal agent addition device. Background Art

[0002] Chemical phosphorus removal mainly involves adding chemicals to phosphorus-containing wastewater. The chemicals react with the wastewater to produce phosphate precipitates, thus removing phosphorus from the wastewater.

[0003] In the chemical phosphorus removal process, the phosphorus removal capacity varies depending on the quantitative dosage of the reagent. Therefore, after detecting the phosphorus content in wastewater, a reagent dosage matching the phosphorus content needs to be added to remove the phosphorus from the wastewater. However, in existing reagent dosing devices, it is difficult to quantitatively control the reagent dosage, resulting in situations where insufficient reagent dosage affects the phosphorus removal effect, while excessive reagent dosage leads to waste. Therefore, it is urgent to design a reagent dosing device for chemical phosphorus removal to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a chemical phosphorus removal agent addition device to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A chemical phosphorus removal agent addition device includes an addition tank, an outer cylinder at the bottom of the addition tank, a metering drum rotatably connected to the inner wall of the outer cylinder via a bearing, a motor fixedly mounted on the outer wall of the outer cylinder, and one end of the metering drum mounted on the output shaft of the motor, an agent groove on the outer wall of the metering drum, a discharge pipe with a solenoid valve mounted on the outer wall of the bottom of the addition tank, a fixed base fixedly mounted at the bottom of the addition tank, and an insert block slidably connected inside the fixed base, slots on both sides of the outer wall of the outer cylinder, and insert blocks inserted into the slots, a pull rod extending to the outside of the fixed base on the outer wall of the insert block, and a spring connected to the insert block on the inner wall of the fixed base, the spring being sleeved on the outside of the pull rod.

[0007] Furthermore, a transmission cylinder is fixedly installed on the top of the addition tank, and a lifting plate is slidably connected inside the transmission cylinder.

[0008] Furthermore, a second motor is fixedly installed on the outer wall of the bottom of the lifting plate, and a stirring shaft is installed on the output shaft of the second motor.

[0009] Furthermore, stirring rods and lifting plates are respectively provided on the outer wall of the stirring shaft, and the stirring rods and lifting plates are distributed in an alternating structure.

[0010] Furthermore, a motor is fixedly installed on the top of the transmission cylinder, and a lead screw is installed on the output shaft of the motor, with the lifting plate threaded onto the outside of the lead screw.

[0011] Furthermore, guide grooves are provided on the inner walls of both sides of the transmission cylinder, and guide blocks that are slidably connected inside the guide grooves are provided on the outer walls of both sides of the lifting plate.

[0012] Furthermore, a medicine inlet hopper is fixedly installed on the outer wall of one side of the addition tank, and an inlet pipe is fixedly installed on the top of the addition tank.

[0013] In the above technical solution, this utility model provides a chemical phosphorus removal agent addition device.

[0014] The device consists of an outer cylinder, a metering drum, a motor, a reagent tank, and a through channel. Since the space of the reagent tank is fixed, the amount of reagent inside is also fixed. The motor drives the metering drum to rotate, allowing a fixed amount of reagent to be added into the chemical phosphorus removal equipment. This achieves the function of metering addition, which enables precise control of the reagent amount and avoids the problems of insufficient reagent addition affecting the phosphorus removal effect and excessive reagent addition leading to waste.

[0015] With the help of a fixed seat, insert, slot, pull rod and spring, pulling the pull rod moves the insert out of the slot, and the outer cylinder can be pulled down to remove it from the addition tank. The outer cylinder can be replaced according to the amount of medicine to be added, and it has a wide range of applications.

[0016] The system consists of a lifting plate, a second motor, a stirring shaft, a stirring rod, a lifting plate, a third motor, and a lead screw. The second motor drives the stirring shaft to rotate, which in turn drives the stirring rod and the lifting plate to rotate laterally, thus mixing the chemicals with each other or with water. Simultaneously, the third motor drives the lead screw to rotate and engage with the lifting plate thread, enabling the lifting plate to move the second motor, the stirring shaft, and the lifting plate up and down. This lifts the chemical mixture inside the addition tank. The combination of lateral stirring and vertical lifting ensures a more uniform mixing of the chemicals with each other or with water.

[0027] By setting the reagent tank 5 to a fixed size, the reagent contained in the reagent tank 5 is also a fixed quantity.

This allows for quantitative control of the reagent, avoiding the problems of insufficient reagent addition affecting the phosphorus removal effect and excessive reagent addition leading to waste.

[0028] In one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, a transmission cylinder 12 is fixedly installed on the top of the addition tank 1, and a lifting plate 13 is slidably connected inside the transmission cylinder 12. When the lifting plate 13 is raised or lowered, it can drive the motor 14, the stirring shaft 15, the stirring rod 16 and the lifting plate 17 to rise or fall.
