Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a coagulant uniformly dosing device for sewage treatment. Background Art

[0002] In the process of sewage treatment, sewage needs to be coagulated. Coagulation refers to the aggregation process of colloidal particles and tiny suspended matter in water. The coagulation process is to add chemicals during sewage treatment to make impurities coagulate and flocculate. The substance that can play the role of flocculation and coagulation in the coagulation process is called coagulant. Coagulants are mainly used for the purification of drinking water, the treatment of industrial wastewater and special water quality.

[0003] However, in the existing sewage treatment process, coagulants are manually added to the sewage, resulting in uneven coagulant addition, which is not conducive to the coagulation and flocculation of impurities in the sewage, poor sewage treatment effect, high labor intensity for workers, time-consuming and labor-intensive, and reduced sewage treatment efficiency.

Example

[0025] like Figure 1-5As shown, the utility model provides a coagulant uniform delivery device for sewage treatment, including a sewage treatment device body 1, the sewage treatment device body 1 includes a treatment tank 2, a water outlet 21 is fixedly installed on the left bottom end of the treatment tank 2, a delivery box 3 is fixedly installed on the top of the treatment tank 2, a support bracket 4 is fixedly installed on the right side of the treatment tank 2, a uniform delivery unit is arranged inside the delivery box 3, a mixing unit is arranged inside the treatment tank 2, the uniform delivery unit includes a delivery mesh plate 31 slidably mounted on the inner wall of the delivery box 3, resistance blocks 32 are fixedly installed on the top and sides of the delivery mesh plate 31, movable grooves 33 are opened on the inner wall of the delivery box 3, and a limiting vertical rod 34 is fixedly installed on the inner bottom end of the movable groove 33, the limiting vertical rod 34 runs through the four sides of the delivery mesh plate 31, and the outer surface of the limiting vertical rod 34 is located below the delivery mesh plate 31 and is movably sleeved with a return spring 35.

[0026] Furthermore, by throwing the coagulant on the top of the delivery mesh plate 31 inside the delivery box 3, the delivery mesh plate 31 is coordinated to make the coagulant fall into the inside of the treatment tank 2 along the mesh holes and be evenly mixed in the sewage. Example

[0027] like Figure 1-5 As shown, based on Example 1, the utility model provides a technical solution: preferably, the mixing unit includes a bidirectional motor 22 fixedly installed in the middle position of the bottom of the processing tank 2, a stirring rod 23 is fixedly installed on the top output end of the bidirectional motor 22, and a stirring blade 24 is fixedly sleeved on the outer surface of the stirring rod 23.

[0028] Furthermore, the top output end of the bidirectional motor 22 drives the stirring rod 23 to cause the stirring blades 24 to stir the sewage at a uniform speed, so that the coagulant is evenly integrated into the sewage, thereby improving the flocculation efficiency. Example

[0029] like Figure 1-5 As shown, on the basis of Examples 1-2, the utility model provides a technical solution: preferably, a transmission box 25 is fixedly installed on the bottom output end of the bidirectional motor 22, the other end of the transmission box 25 is fixedly installed on the bottom end of the support bracket 4, a driving rod 26 is arranged on the top of the other end of the transmission box 25, a transmission box 27 is arranged on the other end of the driving rod 26, the right top of the transmission box 27 is welded to the top of the support bracket 4, a driving wheel 28 is fixedly installed on the other end of the driving rod 26 on the right side of the inside of the transmission box 27, a driving belt 29 is movably sleeved on the outer surface of the driving wheel 28, a driven wheel 210 is movably sleeved inside the other end of the transmission belt 29, a toggle plate 211 is fixedly installed on the output end of the driven wheel 210, and the toggle plate 211 rotates and fits on the top of the delivery mesh plate 31.

[0030] Furthermore, the bottom output end of the bidirectional motor 22 is utilized to drive the transmission box 1 25 and the driving rod 26 to cause the internal components of the transmission box 2 27 to rotate, so that the toggle plate 211 follows the uniform rotation, and then rotates on the top of the delivery mesh plate 31, so that the coagulant is evenly spread on the top of the delivery mesh plate 31, which is convenient for uniform delivery. At the same time, when the toggle plate 211 rotates, its other end contacts the resistance block 32 to push it downward, and the resistance block 32 is utilized to drive the delivery mesh plate 31 to follow the downward movement and slide on the outer surface of the limiting vertical rod 34 and squeeze the reset spring 35. When the toggle plate 211 is intertwined with the resistance block 32 and loses the driving force, the delivery mesh plate 31 is forced to rebound and reset under the elastic counter-driving force of the reset spring 35, thereby causing the delivery mesh plate 31 to reciprocate up and down, promoting the delivery of the coagulant and preventing the mesh from being blocked.

[0031] The working principle of the coagulant uniform delivery device for sewage treatment will be described in detail below.

[0032] like Figure 1-5 As shown, when in use, the coagulant is thrown into the top of the delivery mesh plate 31 inside the delivery box 3, and the delivery mesh plate 31 is used to make the coagulant fall into the treatment tank 2 along the mesh holes and evenly mix in the sewage. The top output end of the bidirectional motor 22 drives the stirring rod 23 to cause the stirring blade 24 to stir the sewage at a uniform speed, so that the coagulant is evenly integrated in the sewage, thereby improving the flocculation efficiency. At the same time, the bottom output end of the bidirectional motor 22 drives the transmission box 1 25 and the driving rod 26 to cause the internal components of the transmission box 2 27 to rotate, so that the toggle plate 211 follows the uniform rotation, thereby causing it to rotate. The toggle plate 211 moves on the top of the delivery mesh plate 31, so that the coagulant is evenly spread on the top of the delivery mesh plate 31, which is convenient for uniform delivery. At the same time, when the toggle plate 211 rotates, its other end contacts the resistance block 32 to push it downward, and the resistance block 32 is used to drive the delivery mesh plate 31 to slide downward on the outer surface of the limiting vertical rod 34 and squeeze the reset spring 35. When the toggle plate 211 and the resistance block 32 are intertwined and lose the driving force, the elastic counter-driving force of the reset spring 35 causes the delivery mesh plate 31 to rebound and reset, thereby making the delivery mesh plate 31 reciprocate up and down, promoting the delivery of the coagulant and preventing the mesh from being blocked.

[0033] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
