Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wastewater treatment agent addition, and in particular to a wastewater treatment agent addition device. Background Technology
[0002] With the continuous development of industry, environmental protection is of utmost importance. At present, it is necessary to treat and recycle sewage to save water resources. This requires physical filtration and chemical treatment of the collected sewage. In the process of sewage filtration, some larger garbage will be filtered out first, mainly including animal feces, paper scraps, and man-made plastic waste. In the subsequent treatment process, we need to use some chemical treatment methods.
[0003] In the process of chemically treating wastewater, we need to add wastewater treatment agents, mainly polyacrylamide. During this process, the polyacrylamide needs to be mixed in the correct proportions and dissolved in water. The final solution is then used to clean the wastewater. Currently, most methods involve manually adding polyacrylamide to water at a uniform and slow rate using a container. This process may cause the polyacrylamide to clump together, leading to incomplete dissolution. Furthermore, the manual addition process can result in variations in the pouring rate and the amount added, affecting work efficiency. Utility Model Content

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0029] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth. Example 1
[0030] Reference Figure 1-7 This is the first embodiment of the present invention, which provides a wastewater treatment agent adding device, which includes a stirring assembly 100, which includes a housing 101, support plates 102 symmetrically arranged on both sides of the housing 101, a flat plate 103 connected to the support plates 102 at the top of the housing 101, a support plate 104 above the flat plate 103, a discharge hole 105 opened on the bottom circumferential side wall, and a transmission component 106. There are two sets of support plates 102 symmetrically arranged, and the top ends of the two sets of support plates 102 are fixedly connected to the flat plate 103.
[0031] Furthermore, the flat plate 103 includes a horizontal region 103a and an arc-shaped region 103b. The support plate 104 is above the horizontal region 103a. The horizontal region 103a and the support plate 104 are coaxially connected by a first through hole 103a-1 and a second through hole 104a. The arc-shaped region 103b is connected by a third through hole 103b-1.
[0032] Furthermore, the transmission component 106 includes a rotating rod 106a, a drive motor 106b, a first transmission gear 106c, a second transmission gear 106d, and a stirring rod 106e. The rotating rod 106a extends from the bottom of the housing 101 through the first through hole 103a-1 and the second through hole 104a.
[0033] Furthermore, the rotating rod 106a is connected to the output end of the drive motor 106b on the side near the support plate 104. The rotating rod 106a is located between the plate 103 and the support plate 104 and is fixedly connected to the first transmission gear 106c and the second transmission gear 106d. The stirring rod 106e is located on the circumferential side wall inside the box 101 and is fixedly connected to the stirring rod 106e.
[0034] Furthermore, the teeth of the first transmission gear 106c are evenly distributed, and the second transmission gear 106d includes a tooth groove section 106d-1 and a groove section 106d-2. The tooth groove spacing between the teeth on the first transmission gear 106c and the second transmission gear 106d is the same.
[0035] Specifically, the drive motor 106b can be set to a slower speed. During the rotation of the drive motor 106b, it will drive the first transmission gear 106c and the second transmission gear 106d to rotate simultaneously, which in turn drives the stirring rod 106e to rotate. At this time, by adding an appropriate amount of treatment agent, the water can be stirred, thereby dissolving the treatment agent in the water. This process can make the treatment agent dissolve more evenly. The stirring rod 106e is set at an angle, which allows the stirring rod 106e to form a vortex more quickly when it comes into contact with the water, thereby accelerating the stirring rate of the water flow. Example 2
[0036] Reference Figure 1-7 This is the second embodiment of the present invention. Unlike the previous embodiment, it also includes a material conveying component 200, which is set through the plate 103. It includes a material conveying hopper 201, a rotating gear disk 202 that cooperates with the transmission component 106, and a linkage column 203. The material conveying hopper 201 is fixedly connected to the bottom of the arc-shaped area 103b. The bottom of the material conveying hopper 201 is a hollow column, and a first screen plate 201a is provided in the hollow column.
[0037] Furthermore, the rotating gear disk 202 meshes with the teeth of the first transmission gear 106c and the second transmission gear 106d. Two sets of fixed platforms 202a are symmetrically fixed on the rotating gear disk 202. Locking bolts 202a-1 are provided through the fixed platforms 202a. The locking bolts 202a-1 press and lock the linkage column 203.
[0038] Furthermore, the linkage column 203 includes a rotating column 203a that passes through the third through hole 103b-1, a stirring component 203b that is fixedly connected to the bottom of the rotating column 203a, and a second sieve plate 203c that is fixedly connected to the bottom of the stirring component 203b. The circumferential cross-section of the stirring component 203b is the same as the cross-section of the hollow column of the conveying hopper 201. Both the first sieve plate 201a and the second sieve plate 203c have leakage holes K.
[0039] Furthermore, a cutting plate 203a-1 is fixedly connected to the circumferential surface of the rotating column 203a below the arc-shaped area 103b, and the cutting plate 203a-1 moves along the inner annular surface of the conveying hopper 201.
[0040] Specifically, the drive motor 106b drives the first transmission gear 106c and the second transmission gear 106d to rotate via the rotating rod 106a. One set of the first transmission gear 106c and the second transmission gear 106d meshes with the rotating gear disk 202, thereby driving the rotation of the rotating gear disk 202. After the rotating gear disk 202 rotates, it drives the rotation of the rotating column 203a. Due to the locking bolt 202a-1 and the rotating column 203a, the rotating gear disk 202 can drive the rotation of the fixed platform 202a after it rotates. When the fixed platform 202a rotates, the friction between the locking bolt 202a-1 and the connecting rod 203 can drive the entire connecting rod 203 to rotate. Figure 6 As shown, the end of the locking bolt 202a-1 can be made of an arc plate that matches the arc surface of the connecting rod 203 to achieve the locking effect. The contact surface of the arc plate can be made of a material with high friction. It should be noted that the locking bolt 202a-1 only pushes the arc plate forward and does not drive the arc plate to rotate during the rotation process.
[0041] Furthermore, when the linkage rod 203 rotates, it will cause the cutting plate 203a-1 below to rotate as well. At this time, the rotation of the cutting plate 203a-1 will scrape off the treatment agent adhering to the surface of the conveying hopper 201. The cutting plate 203a-1 has a protrusion in the axial direction, which can better cut the accumulated treatment agent. During this process, the stirring component 203b will also rotate. The stirring component 203b is spiral. Since the circumferential cross surface of the stirring paddle 203b is the same as the cross-section of the hollow column of the conveying hopper 201, the treatment agent conveyed each time will be evenly distributed. When the treatment agent reaches the bottom, it passes through the first screen plate 201a. Only when the position of the leakage hole K on the first screen plate 201a and the second screen plate 203c overlaps will the treatment agent be added into the box 101 to mix and dissolve with water.
[0042] Furthermore, it can adapt to different treatment agents. When the addition rate of some solvents may differ significantly from the stirring rate, the locking bolt 202a-1 can be loosened to allow the sliding rotating gear disk 202 to engage with the second transmission gear 106d. When the second transmission gear 106d rotates to the point where the teeth of the groove section 106d-1 engage with the teeth of the rotating gear disk 202, it will drive the rotation of the connecting column 203. During the rotation of the groove section 106d-2 on the second transmission gear 106d, it does not engage with the transmission gear disk 202, so no stirring is formed during this process, thereby controlling the addition rate of the treatment agent. Finally, the adjusted solution can be collected through the discharge hole 105 and used for wastewater cleaning.
