Specific embodiment
Embodiment 1
As shown in Figure 1, a kind of self-priming filling mechanism of acid-base neutralization device, the flowmeter 1 including connecting waste tank, institute The flowmeter 1 stated is connected with self-priming feed pipe 2, and check valve assembly 3 is connected on the self-priming feed pipe 2, and described is unidirectional Valve module 3 connects neutralizer storage tank.Flowmeter 1 is connected with waste liquid flow control valve 13, and check valve assembly 3 is connected with neutralizer tune Valve 14 is saved, self-priming feed pipe 2 is connected with liquid liquid mixer 15.Waste liquid flow control valve 13 and neutralizer regulating valve 14 can be cut Only valve or diaphragm valve.
In the present embodiment, it when waste liquid to be neutralized flows through flowmeter 1, can be adjusted by waste liquid flow control valve 13 Flow when waste liquid to be neutralized is flowed into self-priming feed pipe 2, according to fluid dynamic principle, connects check valve assembly 3 Position generate negative pressure, check valve assembly 3 is promoted to open, and check valve assembly 3 connect neutralizer storage tank, neutralizer enter from Waste liquid is neutralized in inspiration expects pipe 2.
It will be appreciated by those skilled in the art that according to the acid-base value of waste liquid, the neutralizer of use is different, as waste liquid is Acidity, then neutralizer is alkaline saleratus liquid or sodium hydroxide solution, and if waste liquid is alkalinity, then neutralizer is acid phosphoric acid Solution or hydrochloric acid solution or sulfuric acid solution etc..
It should also be appreciated by one skilled in the art that check valve assembly 3 can connect 2 and above by pipeline arranged side by side Neutralizer storage tank, the neutralizer type and acid-base value in different neutralizer storage tanks are different.
In the present embodiment, the both ends of self-priming feed pipe 2 are feed end 4 and discharge end 5, and feed end 4 connects flowmeter 1, Self-priming channel 6 is equipped between feed end 4 and discharge end 5, the self-priming channel 6 is located on the side wall of self-priming feed pipe 2, single It is located in self-priming channel 6 to valve module 3.
The direction of the internal diameter of self-priming feed pipe 2 from feed end 4 toward discharge end 5 tapers into, and the self-priming channel 6 is close Discharge end 5, since internal diameter component becomes smaller, flow velocity component becomes larger, and when reaching self-priming channel 6, self-priming channel 6 is larger Larger negative pressure is generated under flow velocity, the opening of check valve assembly 3 becomes sensitive, leads to so as to which neutralizer is made to be rapidly introduced into self-priming Neutralization reaction is carried out in road 6.
Preferably, the runner of cone, flow velocity are formed inside self-priming feed pipe 2 and along the direction of feed end 4 toward discharge end 5 It becomes larger, self-priming channel 6 is vertical with the runner of cone.
Commercially available check valve may be used in check valve assembly 3, in the present embodiment, employs a kind of simple in structure unidirectional Valve module 3, as shown in Figure 1, check valve assembly 3 includes valve seat 7, the valve seat 7 connection self-priming channel 6 and with self-priming channel 6 It is tightly connected, one-way slabs 8 in a ring is equipped in the valve seat 7, the one-way slabs 8 is set close to one end of self-priming channel 6 There is sealing ring 9, pressure is equipped with plate 10 sealing together on sealing ring 9, and the sealing plate 10 is connected with the spring in tensional state 11, and the spring 11 is fixed on valve seat 7.
There is gap, which is used for the circulation of neutralizer between 7 inner wall of sealing plate 10 and valve seat.Likewise, sealing plate 10 outer diameter is less than the internal diameter of self-priming channel 6, and there is also gaps with self-priming channel 6 for sealing plate 10, circulate, are flowed into for neutralizer It is neutralized in self-priming channel 6 with waste liquid.
The operation principle of the utility model is:
With reference to shown in Fig. 3, flowmeter 1 connects feed pump 20, and feed pump 20 connects waste tank 21, set in waste tank 21 There is the first pH meter 24, self-priming feed pipe 2 connects neutralizer storage tank, and neutralizer storage tank is included in acid acceptor storage tank 22 and alkalinity With agent storage tank 23, discharge end 5 is divided into two-way, first via connection surge tank 26 after connecting liquid liquid mixer 15, and surge tank 26 is used back 27 connection waste tank 21 of material pump, the second tunnel connection discharge tube are equipped with the second pH meter 25 in the exit of liquid liquid mixer 15.
Waste liquid is pumped into self-priming feed pipe 2 by feed pump 20 by flowmeter, and flow, waste liquor stream are read by flowmeter 1 During through self-priming 2 inside of feed pipe, negative pressure is formed in self-priming channel 6, sealing plate 10 is detached from sealing ring after overcoming the pulling force of spring 11 9, neutralizer enters self-priming channel 6 and is mixed with the waste liquid in self-priming feed pipe 2, is uniformly mixed simultaneously after liquid liquid mixer 15 It neutralizes, the pH value of the liquid after being neutralized with the detection of the second pH meter 25, if pH value is up to standard, then direct emission, if pH value is not up to standard With entering in surge tank 26, it is pumped into waste tank 21 with feed back pump 27.Again by adjusting 13 He of waste liquid flow control valve Neutralizer regulating valve 14 adjusts the corresponding amount of waste liquid and neutralizer, makes relief liquor pH value up to standard.
Embodiment 2
As shown in Fig. 2, the present embodiment and the structure and the course of work of embodiment 1 are essentially identical, the difference lies in valve seats One piece of fixed plate 12 in a ring is additionally provided on 7, described 11 one end of spring is connect with fixed plate 12, the other end and sealing plate 10 Connection.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute Described specific embodiment can be done various modifications or additions or using similar by belonging to those skilled in the art Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
Although be used more herein flowmeter 1, self-priming feed pipe 2, check valve assembly 3, feed end 4, discharge end 5, Self-priming channel 6, valve seat 7, one-way slabs 8, sealing ring 9, sealing plate 10, spring 11, fixed plate 12, waste liquid flow control valve 13, in With agent regulating valve 14, liquid liquid mixer 15, feed pump 20, waste tank 21, acid acceptor storage tank 22, antalkali storage tank 23rd, the first pH meter 24, the second pH meter 25, surge tank 26, feed back pump the terms such as 27, but the possibility using other terms is not precluded Property.The use of these terms is merely for the convenience of describing and explaining the nature of the invention, is construed as any A kind of additional limitation is all contrary to the spirit of the present invention.
