Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and particularly relates to an integrated chemical feeder with adjustable liquid medicine ratio. Background Art

[0002] In sewage treatment, chemical dosing is an important treatment method. Chemical dosing refers to quantitatively adding specific chemical agents to sewage to achieve the purpose of improving sewage quality, removing pollutants or promoting the treatment process. The dosage, dosing point and dosing method of chemical agents need to be carefully designed and optimized according to factors such as the water quality, water volume, treatment process and treatment objectives of the sewage. If the dosing is improper, problems such as poor treatment effect, increased treatment cost and even secondary pollution may occur.

[0003] At present, in the process of chemical dosing, the control of the mixing ratio of various chemical agents is not precise and convenient enough, and the chemical agents are not fully mixed with water during the dosing process, and subsequent separate stirring equipment is needed for stirring and mixing, which increases the working time. Content of the Utility Model

[0004] The purpose of the utility model is to provide an integrated chemical feeder with adjustable liquid medicine ratio, which can more precisely control the dosing ratio of each chemical agent and make it evenly mixed.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An integrated chemical feeder with adjustable liquid medicine ratio includes a chemical dosing connecting pipe, in which a cut-off chemical dosing support pipe and a central chemical dosing pipe coaxial with it are fixed.

[0007] An inner chemical dosing flow channel is formed inside the cut-off chemical dosing support pipe, and an outer chemical dosing flow channel is formed between the outer wall of the cut-off chemical dosing support pipe and the inner wall of the chemical dosing connecting pipe.

[0008] A plurality of outer ring chemical dosing nozzles are fixed on the outer wall of the cut-off chemical dosing support pipe, and a plurality of inner ring chemical dosing nozzles are fixed on the inner wall of the cut-off chemical dosing support pipe.

[0009] A plurality of central chemical dosing nozzles are fixed on the outer side of the central chemical dosing pipe.

[0010] A cut-off control mechanism and a swirl control mechanism are arranged in the chemical dosing connecting pipe.

[0011] Preferably, a decentralized chemical dosing mechanism is provided on the flow intercepting chemical dosing support pipe. There are multiple chemical dosing cylinder receiving grooves on the side wall of the flow intercepting chemical dosing support pipe extending along the direction parallel to its axis. The decentralized chemical dosing mechanism includes a decentralized chemical dosing receiving cylinder fixed in the chemical dosing cylinder receiving groove. A conveying pipe winding wheel is rotatably connected in the decentralized chemical dosing receiving cylinder. A decentralized chemical dosing conveying pipe is wound on the conveying pipe winding wheel. A chemical dosing arrangement ball is fixed at the outer end of the decentralized chemical dosing conveying pipe. Multiple decentralized chemical dosing nozzles are fixed on the chemical dosing arrangement ball. Each decentralized chemical dosing nozzle is communicated with the decentralized chemical dosing conveying pipe.

[0012] Explanation: The decentralized chemical dosing mechanism is used to supplement and add chemicals to the water to be treated. The average density of each chemical dosing arrangement ball is designed to be the same as that of water, so that the chemical dosing arrangement balls can be evenly dispersed and suspended in the water, facilitating the uniform spraying of the chemicals.

[0013] Preferably, there are multiple intercepting plate receiving grooves on the inner side wall of the chemical dosing connecting pipe. The intercepting control mechanism includes an intercepting control plate connected in the intercepting plate receiving groove through a fixed hinge;

[0014] There is a deflection control through hole communicating the inside and outside on the side wall of the chemical dosing connecting pipe. A deflection control rod is slidably connected in the deflection control through hole. A deflection control connecting plate is fixed on the side of the intercepting control plate. There is a deflection control sliding groove on the deflection control connecting plate. A short column for sliding groove cooperation is fixed at the end of the deflection control rod located inside the chemical dosing connecting pipe. The short column for sliding groove cooperation is slidably connected in the deflection control sliding groove. A driving receiving cylinder is fixed at the position of the deflection control through hole on the outside of the chemical dosing connecting pipe. A deflection control driving rod for driving the deflection control rod to move is arranged in the driving receiving cylinder.

[0015] Explanation: The intercepting control mechanism can adjust the flow rate of the water flowing through the outer channel of the chemical dosing flow passage, so that the water flowing through the inner channel and the outer channel of the chemical dosing flow passage forms a flow rate difference. Under the action of the flow rate difference, it is beneficial to the uniform dispersion and mixing of the chemicals.

[0016] Preferably, the swirl control mechanism includes a swirl separation support ring fixed in the chemical dosing connecting pipe and coaxial with it. There are multiple rotation outer shaft matching holes penetrating radially on the side wall of the chemical dosing connecting pipe. There are multiple rotation inner shaft matching holes penetrating radially on the side wall of the swirl separation support ring. A swirl control outer shaft is rotatably connected in the rotation outer shaft matching hole. A swirl control inner shaft is rotatably connected in the rotation inner shaft matching hole. An outer ring swirl control plate is fixed on the swirl control outer shaft. An inner ring swirl control plate is fixed on the swirl control inner shaft;

[0017] A swirl drive control housing is fixed on the outside of the chemical addition connecting pipe at the position of the rotary outer shaft fitting hole. The swirl control outer shaft is a hollow shaft, and a plurality of swirl control inner shafts respectively pass through the swirl control outer shaft and extend into the interior of the swirl drive control housing. An outer shaft drive motor for driving the rotation of the swirl control outer shaft is fixed in the swirl drive control housing, and an inner shaft drive motor for driving the rotation of the swirl control inner shaft is fixed in the swirl drive control housing.

[0018] Note: The swirl control mechanism can independently control the water flow in the inner channel and outer channel of the chemical addition flow respectively, so that when the water flows along the axis of the chemical addition connecting pipe, it also rotates around the axis of the chemical addition connecting pipe, generating a certain swirl, which is beneficial to the full mixing of the chemicals.

[0019] Compared with the prior art, the beneficial effects of the present utility model are reflected in the following aspects:

[0020] 1. The structure of the present utility model is reasonably designed. Each outer ring chemical addition nozzle, inner ring chemical addition nozzle and central chemical addition nozzle are controlled by independent valves to open and close each nozzle. By controlling the number of nozzles actually spraying the chemicals, it is convenient to control the addition ratio of various chemicals, and the chemicals can be fully mixed with water during the input process without the need for subsequent separate stirring and mixing. Even if stirring and mixing are required again, the stirring and mixing time can be greatly reduced;

[0021] 2. The present utility model is convenient to operate. The flow rate of the water flowing through the outer channel of the chemical addition flow can be adjusted by using the throttling control mechanism, so that the water flowing through the inner channel and outer channel of the chemical addition flow forms a flow rate difference. Under the action of the flow rate difference, the two water flows can quickly merge and mix together after the end of the throttling chemical addition support pipe, which is beneficial to the uniform dispersion and mixing of the chemicals;

[0022] 3. The present utility model can independently control the water flow in the inner channel and outer channel of the chemical addition flow by using the swirl control mechanism, so that when the water flows along the axis of the chemical addition connecting pipe, it also rotates around the axis of the chemical addition connecting pipe, generating a certain swirl, which is beneficial to the full mixing of the chemicals and water in the inner channel and outer channel of the chemical addition flow respectively;

[0023] 4. The present utility model uses a decentralized chemical addition mechanism to supplement and add chemicals to the water to be treated. The average density of each chemical addition arrangement ball is designed to be the same as that of water, so that the chemical addition arrangement balls can be evenly dispersed and suspended in the water, which is convenient for the uniform dispersion spraying of the chemicals.

[0043] Embodiment 3:

[0044] On the basis of Embodiment 2, as Figure 5 shown in the figure, the swirl control mechanism 30 includes a swirl separation support ring 31 fixed inside and coaxial with the chemical addition communication pipe 10. A plurality of rotation outer shaft fitting holes 321 penetrating radially are provided on the side wall of the chemical addition communication pipe 10. A plurality of rotation inner shaft fitting holes 322 penetrating radially are provided on the side wall of the swirl separation support ring 31. A swirl control outer shaft 331 is rotatably connected inside the rotation outer shaft fitting hole 321.

[0045] A swirl drive control accommodating shell 35 is fixed to the outside of the chemical addition communication pipe 10 at the position of the rotation outer shaft fitting hole 321.

[0046] Both the outer shaft drive motor 351 and the inner shaft drive motor 352 are servo motors.

[0047] It should be noted that each outer ring chemical addition nozzle 131, inner ring chemical addition nozzle 132, central chemical addition nozzle 133, dispersion chemical addition nozzle 155, fixed hinge 211, deflection control drive rod 226, outer shaft drive motor 351, and inner shaft drive motor 352 are all prior arts and are not specifically limited here.

[0048] During the actual application process of the present utility model, the chemical addition communication pipe 10 is connected to the input pipe of the water treatment equipment, and the swirl control mechanism 30 faces the upstream end;

[0049] When the water to be treated flows through the chemical addition connecting pipe 10 during the conveying process, treatment chemicals are sprayed into the water to be treated by the synergistic action of a plurality of outer ring chemical addition nozzles 131, inner ring chemical addition nozzles 132, and a central chemical addition nozzle 133;

[0050] An inner chemical addition flow passage is formed inside the intercepting chemical addition support pipe 11, and an outer chemical addition flow passage is formed between the outer side wall of the intercepting chemical addition support pipe 11 and the inner side wall of the chemical addition connecting pipe 10;

[0051] By using the intercepting control mechanism 20, the flow rate of the water flowing through the outer chemical addition flow passage can be adjusted, so that a flow rate difference is formed between the water flowing through the inner chemical addition flow passage and the outer chemical addition flow passage. Under the action of the flow rate difference, the two water flows can be quickly fused and mixed together after the end of the intercepting chemical addition support pipe 11, which is beneficial to the uniform dispersion and mixing of the chemicals;

[0052] In the intercepting control mechanism 20, the inner rod of the deflection control driving rod 226 extends to drive the deflection control rod 22 to move along the axis of the deflection control through hole 221, and the deflection control rod 22 then drives the intercepting control plate 21 to rotate around the axis of the fixed hinge 211. A plurality of intercepting control plates 21 are blocked in the outer chemical addition flow passage, changing the cross-sectional area of the outer chemical addition flow passage. When the total input flow rate is constant, the change of the flow cross-section further changes the flow rate of the water in the outer chemical addition flow passage;

[0053] By using the swirl control mechanism 30, the water flows in the inner chemical addition flow passage and the outer chemical addition flow passage can be controlled independently, so that when the water flows along the axis of the chemical addition connecting pipe 10, it also rotates around the axis of the chemical addition connecting pipe 10 to generate a certain swirl, which is beneficial to the full mixing of the chemicals and the water in the inner chemical addition flow passage and the outer chemical addition flow passage respectively;

[0054] The outer shaft drive motor 351 drives the swirl control outer shaft 331 to rotate, and the swirl control outer shaft 331 then drives the outer ring swirl control plate 33 to deflect, changing the water in the outer chemical addition flow passage to generate a swirl,

[0055] The inner shaft drive motor 352 drives the swirl control inner shaft 341 to rotate, and the swirl control inner shaft 341 then drives the inner ring swirl control plate 34 to deflect, changing the water in the inner chemical addition flow passage to generate a swirl;

[0056] Each of the outer ring chemical addition nozzles 131, inner ring chemical addition nozzles 132, and the central chemical addition nozzle 133 is controlled by an independent valve to open and close each nozzle. By controlling the number of nozzles actually spraying the chemicals, the addition ratio of various chemicals can be controlled;

[0057] The dispersed chemical dosing mechanism 15 is used to supplement and add chemicals to the water to be treated. The average density of each chemical dosing arrangement ball 154 is designed to be the same as that of water, so that the chemical dosing arrangement ball 154 can be suspended in the water. The servo motor drives the conveying pipe winding wheel 152 to rotate, so that the dispersed chemical dosing conveying pipe 153 is released from the conveying pipe winding wheel 152. Driven by the impact of the water flow, the chemical dosing arrangement ball 154 drags the dispersed chemical dosing conveying pipe 153 to move along the axis of the dispersed chemical dosing containing cylinder 151. Each chemical dosing arrangement ball 154 is arranged dispersedly in the chemical dosing connecting pipe 10. The chemical is conveyed to the dispersed chemical dosing conveying pipe 153 through a delivery pump, and finally the chemical is sprayed into the water through each dispersed chemical dosing nozzle 155.

[0058] The chemicals include a coagulant, a flocculant, an oxidant, and an acid-base regulator. Each outer ring chemical dosing nozzle 131, inner ring chemical dosing nozzle 132, central chemical dosing nozzle 133, and dispersed chemical dosing nozzle 155 is responsible for spraying only one type of chemical.
