Detailed implementation manners

[0025] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model will be given in conjunction with the accompanying drawings of the specification.

[0026] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0028] Furthermore, the present utility model is described in detail in conjunction with the schematic diagrams. When describing the embodiments of the present utility model in detail, for the sake of convenience of explanation, the cross-sectional views showing the device structures will be enlarged locally not in accordance with the general scale, and the schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0029] Referring to Figures 1-3, an embodiment of the present utility model provides a sewage treatment device for environmental protection engineering, which includes the following parts:

[0030] The water inlet channel 200 is used to be arranged at the front end of the sedimentation tank, so that when the sewage enters the sedimentation tank, it first flows through the water inlet channel 200 and then enters the sedimentation tank;

[0031] The feeding port 300 is arranged on the water inlet channel 200, and the flocculant is used to be input from the feeding port 300. For example, the feeding port 300 can be directly connected to the source of the flocculant. When the feeding port 300 is opened, the feed automatically drops to realize the feeding process. There is a closing component 400 at the feeding port 300, which is used to realize the closing and opening of the feeding port 300;

[0032] The triggering mechanism 500 is arranged in the water inlet channel 200. When water flows through the triggering mechanism 500, the triggering mechanism 500 will act, thereby controlling the closing component 400 to open the feeding port 300 to realize feeding. When there is no action, the closing component 400 is not driven, so that the closing component 400 keeps the feeding port 300 in a normally closed state;

[0033] The process of controlling the feeding of the present utility model is as follows: the sewage passes through the water inlet channel 200 and then drains into the sedimentation tank. During this process, the triggering mechanism 500 controls the opening of the feeding port 300, so that the feed enters the water inlet channel 200 and is mixed with the flowing sewage, and finally enters the sedimentation tank together. Therefore, when there is no sewage entering, the triggering mechanism 500 does not contact the water flow, so that the feeding port 300 remains closed, thereby stopping the feeding. When there is sewage entering, the feeding action is automatically carried out, thus realizing an effect of automatically controlling the feeding according to whether there is an inlet water behavior, thereby achieving a reasonable control of the feeding behavior, realizing the control of the feeding amount, effectively reducing the waste caused by feeding without water, and reducing the phenomenon of incomplete purification caused by untimely feeding when there is water, and realizing the full utilization of the feed.

[0034] Further, Figure 5 For the intercepted view when a part of the present utility model is stereoscopically cut, refer to Figure 2 and Figure 5 , the closing component 400 includes a sealing plate 401 rotatably arranged at the feeding port 300. In the normal state, the sealing plate 401 is lapped on the orifice surface of the feeding port 300 by gravity, realizing the sealing of the feeding port 300, thereby achieving the closing effect of the feeding port 300. When the triggering mechanism 500 acts, it will touch the sealing plate 401, making it perform a rotational movement, thereby realizing the opening effect of the feeding port 300.

[0035] Further, refer toFigures 3-5 , a touch end 402 is provided on the sealing plate 401. The touch mechanism 500 includes a receiving portion 501 rotatably provided inside the water inlet channel 200. The receiving portion 501 is used to achieve the effect of receiving water flow. For example, a bucket structure can be used. A drain port 502 communicating with the inside of the receiving portion 501 is provided on the outer side of the receiving portion 501. When the water flow passes through the water inlet channel 200, it falls into the receiving portion 501 and then flows out through the drain port 502 and returns to the water inlet channel 200. During this process, a reaction force is formed when the drain port 502 drains water, causing the receiving portion 501 to rotate. A pushing portion 503 for pushing the touch end 402 is movably connected to the receiving portion 501. The pushing portion 503 can adopt a rod structure. When the receiving portion 501 rotates, the pushing portion 503 swings upward under the action of centrifugal force. Therefore, during the rotation with the receiving portion 501, it can touch the touch end 402, thereby pushing the touch end 402 and causing the sealing plate 401 to rotate, so as to achieve the effect of opening the feeding port 300. In this structure, the touch mechanism 500 relies on the potential energy of the water flow to complete the driving effect, so that the utility model can work without relying on too much energy.

[0036] Further, referring to Figure 2 , the total number of the combination of the feeding port 300 and the closing assembly 400 can be multiple and are evenly distributed along the circumferential side of the receiving portion 501. Therefore, the corresponding pushing portions 503 can also be multiple. Since when the receiving portion 501 drains water, the water rotates and discharges to the circumferential side, by increasing the number of the feeding ports 300 and arranging them evenly in position, the flocculant can be scattered more evenly into the sewage during feeding.

[0037] Further, referring to Figures 1-3 , the water inlet channel 200 includes an upper pipeline 201 and a lower pipeline 202. The upper pipeline 201 and the lower pipeline 202 are fixedly connected through a bearing wall 203. The bearing wall 203 is used to carry the feeding material. Then, in cooperation with the outer wall of the upper pipeline 201 and the inner wall of the lower pipeline 202, a circular storage area 100 can be formed on the utility model. The storage area 100 can be used for the one-time stacking of a batch of flocculants. The feeding port 300 is specifically located on the bearing wall 203. Therefore, during feeding, the stacked flocculants directly fall into the water inlet channel 200 from the storage area 100.

[0038] Further, referring to Figure 3, the lower pipeline 202 includes a connected first peripheral wall 202a, a second peripheral wall 202b and a third peripheral wall 202c. The bearing wall 203 is connected between the first peripheral wall 202a and the second peripheral wall 202b. The first peripheral wall 202a is used to cooperate with the formation of the storage area 100. The second peripheral wall 202b has a tapered structure, so that when the flocculant falls, it drops on the second peripheral wall 202b, thus playing a buffering effect and slowly falling downward, and then reaching the third peripheral wall 202c. Therefore, when the sewage flushes onto the third peripheral wall 202c, it can ensure that the flocculant and the sewage flow are fully mixed.

[0039] Further, referring to Figure 3 , the third peripheral wall 202c is arranged close to the drain outlet 502 to ensure that when the sewage is discharged from the drain outlet 502, it can promptly rush onto the third peripheral wall 202c, so as to rely on the potential energy of the water flow to promptly disperse the sprinkled flocculant and increase the mixing effect.

[0040] Further, referring to Figures 1-3 , the present utility model further includes a filtering component 600, which is interceptively arranged on the upper pipeline 201 and above the receiving part 501. Since domestic sewage often contains some large-sized stains, such as food residues, solid garbage, and feces, etc., through the action of the filtering component 600, the large-sized stains in the sewage can be effectively intercepted in advance, so as to play a role in centralized collection when the sewage is subjected to subsequent treatment. For the filtering component 600, structures such as a filter net or an intercepting net can be adopted.

[0041] It should be understood that in the development process of any actual implementation, such as in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those ordinary technical personnel who benefit from this disclosure, without excessive experimentation, the development efforts will be a routine work of design, manufacturing, and production.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
