Detailed Implementation

[0039] In the embodiments of this application, such as Figure 1 , 2 As shown in Figures 3 and 4, the wastewater treatment equipment includes a tank 1. The tank 1 has a common tank structure used for wastewater treatment, preferably a cylindrical tank. The bottom of the tank 1 is provided with a bottom plate 101, which is equipped with a drain pipe 104 and several support legs 102. The support legs 102 are used for support. The drain pipe 104 is connected to the next treatment equipment, preferably a flocculation sedimentation tank. A dosing pipe 103 is provided on the side of the tank 1. The dosing pipe 103 is used to add wastewater treatment agents. For example, if the pH value of the wastewater is too high, hydrochloric acid or other substances are added through the dosing pipe 103 for neutralization; if the pH value is too low, sodium hydroxide or other substances are added through the dosing pipe 103 for neutralization. Other agents used for treating wastewater can also be added, depending on the actual situation.

[0040] The tank body 1 is equipped with an isolation cylinder 2, which extends to the top of the tank body 1. The isolation cylinder 2 is connected to a water inlet pipe 105, which is a water inlet pipe for ore washing wastewater. The outer periphery of the isolation cylinder 2 is provided with several filter holes 201.

[0041] When in use, the wastewater to be treated is poured into the isolation cylinder 2. Solid impurities will be isolated inside the isolation cylinder 2, while the liquid flows into the tank 1 through the filter hole 201. Then, the pH of the wastewater is adjusted by adding chemicals, and finally, it enters the next treatment equipment for flocculation treatment through the drain pipe 104. The operation is simple, can ensure the effect of flocculation treatment, and can also prevent crushed stone from entering the subsequent treatment equipment.

[0042] In a preferred embodiment, a base 4 is provided between the bottom of the isolation cylinder 2 and the base plate 101. The base 4 is cylindrical and contains a slag discharge pipe 6. One end of the slag discharge pipe 6 is connected to the isolation cylinder 2, and the other end is located at the bottom of the base plate 101. After the ore washing wastewater is treated, large impurities such as gravel are discharged through the slag discharge pipe 6.

[0043] The slag discharge pipe 6 includes a fixed pipe 601 located within the base 4; a slag discharge pipe 602 is provided at the bottom end of the fixed pipe 601; the slag discharge pipe 602 is connected to external processing equipment or collection equipment, depending on the actual situation, such as placing a collection bucket below the slag discharge pipe 602 to collect large pieces of impurities discharged. A guide seat 603 is provided at the top end of the fixed pipe 601, located inside the isolation cylinder 2, and the connection is sealed. A guide hole 604 is provided inside the guide seat 603. The guide hole 604 is a conical hole, with the top diameter of the guide hole 604 larger than the bottom diameter, to facilitate the sliding of crushed stone into the fixed pipe 601; the fixed pipe 601 and the isolation cylinder 2 are connected through the guide hole 604.

[0044] In a further embodiment, the isolation cylinder 2 is provided with an adjustment frame 3; the adjustment frame 3 includes a stop block 301 disposed in the guide hole 604, the top of the stop block 301 is conical to facilitate the sliding of gravel, and the bottom of the stop block 301 is adapted to the guide hole 604; the top of the stop block 301 is provided with a movable rod 302; the movable rod 302 slides through the water inlet pipe 105, and a sealing ring is provided at the connection between the movable rod 302 and the water inlet pipe 105. In use, the stop block 301 can be moved up and down by sliding the movable rod 302 up and down; the bottom of the stop block 301 is provided with several sealing gaskets 303. When the stop block 301 is located in the guide hole 604, the sealing gaskets 303 can provide a certain degree of sealing to prevent liquid from entering the fixed pipe 601.

[0045] During processing, the crushed stone is blocked by the baffle 301, preventing both liquid and crushed stone from entering the slag discharge pipe 6. The liquid enters the tank 1 through the filter hole 201. After processing, the baffle 301 is lifted upwards, exposing the guide hole 604, allowing impurities such as crushed stone to enter the slag discharge pipe 6 through the guide hole 604 and be discharged.

[0046] In a further embodiment, a base 4 is provided between the bottom and the base plate 101, and a mixing mechanism 5 is provided between the base 4 and the tank body 1. Specifically, the mixing mechanism 5 includes a motor 501 located at the bottom of the base plate 101. The motor 501 is preferably an existing motor, controlled and adjusted in an existing manner. The output shaft of the motor 501 is provided with a rotating shaft 502, one end of which is rotatably located inside the base 4. Several gears 503 are provided on the rotating shaft 502. An internal gear ring 504 is sleeved on the outer periphery of the base 4, and the internal gear ring 504 meshes with the gears 503. The inner side of the internal gear ring 504 is located inside the base 4, and sealing rings are provided between the upper and lower sides of the internal gear ring 504 and the base 4, thereby ensuring the rotation of the internal gear ring 504 while ensuring the seal between the internal gear ring 504 and the base 4. Several mixing rods 505 are provided on the outer periphery of the internal gear ring 504, and the mixing rods 505 are located inside the tank body 1. In use, starting the motor 501 drives the rotating shaft 502 to rotate, which in turn drives the gear 503 to rotate. The rotation of the gear 503 drives the internal gear ring 504 to rotate, which in turn drives the mixing rod 505 to rotate. This accelerates the mixing of the treated ore washing wastewater and the reagent, increasing the treatment efficiency.
