DETAILED DESCRIPTION

[0021] The embodiments of the utility model are described in detail below, the examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, and are intended to explain the utility model, and cannot be understood as the limitation of the utility model. In the description of the utility model, it is understood that the orientation or position relationship indicated by the terms "upper", "lower", "front", "upper surface" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as the limitation of the utility model.

[0022] Please refer to Figures 1-6 The utility model provides an embodiment: a dosing equipment for water treatment, including tank body 1, one side of tank body 1 is equipped with first connecting pipe 12, and is equipped with spray pipe assembly 4 on first connecting pipe 12, and the upper side of tank body 1 is also equipped with liquid outlet 2;The bottom surface of tank body 1 is also equipped with second connecting pipe 10, and second connecting pipe 10 is connected with the support 7 equipped, one side of second connecting pipe 10 is equipped with first dosing opening 5, and the other side of second connecting pipe 10 is also equipped with second dosing opening 8;Tank body 1 is also equipped with paddle 9, and the rotating shaft of paddle 9 is rotatably connected with the shaft pin seat 11 equipped on support 7.

[0023] In summary, due to the setting of the spray pipe assembly 4, the water source is guided to impact the paddle 9 by the spray pipe assembly 4, and then drives the paddle 9 to rotate, and at the same time, the two dosing openings on the bottom surface of the tank body 1 can add at least two medicaments into the tank body 1, and the medicaments enter the tank body 1 and rotate with the paddle 9, so as to complete the mixing of the water source and the medicaments in the process of the water flowing upward. Based on this, the device uses the water flow to drive the paddle 9 to rotate, so that the paddle 9 does not need an additional driving device, and the greater the flow rate of the water flow, the faster the rotational speed of the paddle, so that the mixing efficiency of the water source and the medicaments can be further improved, so as to solve the problems existing in the prior art. The first dosing opening 5 and the second dosing opening 8 are connected with the medicament pump outside, and a spray head can be installed on the first dosing opening 5 and the second dosing opening 8, so as to further improve the mixing of the medicaments and the water source in the tank body 1 by using the medicament pump to spray the medicaments into the tank body 1.

[0024] In addition, the tank body 1 is arranged in an elliptical shape, and the water flow flows from bottom to top, so that the water flow can stay for a while after entering the tank body 1, thereby prolonging the mixing time of the medicaments and the water flow, and the elliptical tank body 1 is convenient for users to clean the inner wall.

[0025] Further, since the spray pipe assembly 4 includes a throat pipe 40, one end of the throat pipe 40 is connected with the first connecting pipe 12 through the first connecting portion 43. Therefore, the principle of Laval nozzle is used to improve the impact speed of the water flow on the paddle 9.

[0026] At the same time, since the length of the first connecting portion 43 is greater than the length of the first connecting pipe 12, when the first connecting portion 43 is installed on the first connecting pipe 12, the first connecting portion 43 can be close to the paddle 9, thereby improving the impact force of the water flow on the paddle 9, and improving the rotational speed of the paddle 9.

[0027] Specifically, the first connecting portion 43 is an external threaded pipe, and the first connecting portion 43 is further provided with a driving portion 42, so that the driving portion 42 drives the first connecting portion 43 to rotate, and at the same time, the sealing ring is fixed between the opposite surfaces of the driving portion 42 and the first connecting pipe 12, so as to improve the sealing performance of the first connecting pipe 12.

[0028] In addition, since one end of the throat pipe 40 away from the first connecting portion 43 is connected with the water pipe outside through the second connecting portion 41, the pipeline for conveying the water source is simple and convenient to connect with the spray pipe assembly 4; the second connecting portion 41 can be a nut or a flange.

[0029] On the basis of the above scheme, the tank body 1 is also provided with an access opening 3 away from one end of the spray pipe assembly 4, and the access opening 3 is sealed by the provided window assembly 6. Since the access opening 3 is provided, firstly, the user can conveniently overhaul the inside of the tank body 1; secondly, the paddle 9 can also be installed in the tank body 1.

[0030] At the same time, since the window assembly 6 comprises a first flange 60 and a second flange 63, and the provided transparent plate 62 is fixed on the first flange 60 through the second flange 63. Therefore, the user can know the working state of the inside of the tank body 1 in real time through the window assembly 6.

[0031] Further, since the first flange 60 is also provided with a containing groove 61, after the second flange 63 fixes the transparent plate 62 in the containing groove 61, the outer end surface of the second flange 63 is flush with the outer end surface of the first flange 60; in addition, the first flange 60 and the access opening 3 are also provided with a sealing gasket 64, so that the leakage phenomenon at the access opening 3 can be reduced.

[0032] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the utility model, and still fall within the protection scope of the utility model.
