Abstract
The invention discloses a connection structure for a lime feeding tube in water treatment equipment. The connection structure comprises a feeding tube communicated with an acidic wastewater neutralization pond and a lime dissolution pond, wherein the connection sequence of the feeding tube is that: the feeding tube is led out of the lime dissolution pond, and passes through a chemical inlet valve to reach an inlet of a feeding pump; and the feeding tube is led out an outlet of the feeding pump, and passes through a check valve, an outlet valve and a pneumatic valve sequentially to reach the acidic wastewater neutralization pond, and a backflow branch is connected between the outlet valve and the pneumatic valve and passes through a protective valve to reach the lime dissolution pond. By the connection structure, the using amount of materials and the workload in the engineering installation process are reduced, and the cost is reduced; the length of a pipeline is shortened, and pressure loss is reduced, namely energy consumption is reduced, so the feeding pump with small power can be used, and the possibility of blocking the pipeline due to lime deposition is also reduced. Simultaneously, the connection structure is convenient to control, the work efficiency of personnel is improved, and the effect of feeding lime can be better achieved.
Description
Technical field
The present invention relates to a kind of pipe connecting method, the syndeton on a kind of lime medicine feeding pipe road specifically, this syndeton has guaranteed the safety of pipeline, is applicable in the large pipeline of online chemical feeding quantity.
Background technology
At present, pipeline reflux type feeding lime is all adopted in the connection on conventional lime medicine feeding pipe road, the mode of connection of traditional lime medicine feeding pipe is: after chemical feed pipe is drawn by the lime dissolving tank, successively through advancing the medicine valve, vacuum breaker, dosing pump, vacuum breaker, outlet valve, operated pneumatic valve are to the acid waste water neutralization tank, from taking back the stream branch road near the operated pneumatic valve front end, the manual return valve of this branch road warp is to the lime dissolving tank again.The quantity of reflux that the hand-driven return-flow valve gate open is overregulated lime guarantees ducted pressure, and is relevant with several factors because of ducted pressure, so reverse flow valve needs regular adjusting size to guarantee the chemical feeding quantity of lime, also will prevent simultaneously the explosion of lime pipeline.This mode be connected with following shortcoming: the one, the loss pipe when especially distance is distant, has been equivalent to the pipeline of a times multiplex, has not only increased the cost of pipeline but also has increased the pressure loss of pipeline and workload when connecting is installed; The 2nd, the increase of duct length has caused hydraulic loss, has increased energy consumption, and easily causes the deposition of lime and blocking pipe; The 3rd, the increase of duct length causes the increase of pipeline pressure, easily causes the booster of lime pipeline, increases expense and the difficulty of maintenance.
Summary of the invention
It is normal pipeline booster and the lime line clogging problem that occurs in lime dosing process that problem to be solved by this invention is to provide technical problem to be solved in the utility model.
The syndeton of lime medicine feeding pipe of water treatment equipment of the present invention comprises the chemical feed pipe that is communicated with between acid waste water neutralization tank and lime dissolving tank, and the order of connection of described chemical feed pipe is: drawn by the lime dissolving tank, through advancing the medicine valve to the dosing pump entrance; Chemical feed pipe is drawn by dosing pump outlet again, successively through vacuum breaker, outlet valve, pneumavalve to the acid waste water neutralization tank, the connection backflow branch road between outlet valve and pneumavalve, through pressure protection valve to the lime dissolving tank.
As improvement of the present invention, advancing medicine valve access water supply pipe and running water valve thereof to the chemical feed pipe between the dosing pump entrance, be used for the cleaning of pipeline.
Working process of the present invention is, dosing pump promotes lime to the acid waste water neutralization tank, controls the switch of operated pneumatic valve by the on-line monitoring instrument, adds in appropriate lime and the acidity of waste water.Ducted pressure can rise after operated pneumatic valve is closed, and after reaching certain pressure, the pressure protection valve on the backflow branch road can automatically be opened and carry out pressure release, guarantees that ducted pressure can be not too high, has also protected pipeline to avoid booster simultaneously.
The present invention has reduced the use of material and the workload in project installation, has reduced cost; Owing to having shortened duct length, reduced pressure loss, namely reduced energy consumption, can use lower-powered dosing pump, also reduced the possibility because of the lime precipitation blocking pipe.Simultaneously, the present invention controls conveniently, has improved personnel's working efficiency, can better reach the effect of feeding lime.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
As Fig. 1, the syndeton of lime medicine feeding pipe of water treatment equipment of the present invention, lime medicine feeding pipe is used for connecting acid waste water neutralization tank 8 and lime dissolving tank 9, and the order of connection of chemical feed pipe is: drawn by lime dissolving tank 9, through advancing medicine valve 1 to the dosing pump entrance; Advancing medicine valve 1 access water supply pipe and running water valve 2 thereof to the chemical feed pipe between dosing pump 7 entrances.Chemical feed pipe is drawn by dosing pump 7 outlet again, successively through vacuum breaker 3, outlet valve 4, pneumavalve 5 to acid waste water neutralization tank 8, backflow branch road of the connection between outlet valve 4 and pneumavalve 5 through pressure protection valve 7 to lime dissolving tank 9.
The manner connects only need to be good just passable with the pressure setting of protection valve, saved loaded down with trivial details operation, also prevented the explosion of pipeline.dosing pump needs running always when treatment of acidic wastewater, pump into lime in pipeline, the switch that adds the detection control operated pneumatic valve that leans against the line instrument of lime in acid waste water neutralization tank 8, pneumavalve 5 is opened when acidity is excessive, the lime pump can directly pump into lime in neutralization tank, when amount of lime fills up or is excessive, pneumavalve 5 will autoshutdown, this moment, the pressure of pipeline will raise gradually, cause pipeline pressure excessive, when reaching setup pressure value, pressure protection valve 7 will be opened pressure release automatically, to guarantee that ducted pressure prevents pipeline burst, when ducted hypotony, pressure protection valve 7 autoshutdowns, guarantee the pressure of lime current in pipeline, can be fast in the neutralization tank feeding lime.
Lime reflux line of the present invention adopts a kind of mode of connection of pressurize, both can guarantee the dosage of lime, and the safety of pipeline also can be saved the length of pipeline simultaneously, has saved the usage quantity of pipe, has reduced again the workload of installation and maintenance.Owing to adopting straight tube to connect; only need single pipeline to connect; pressurize valve that in addition can auto-switch on reflux line; guarantee ducted pressure within the specific limits, when ducted pressure surpassed setting pressure, valve was opened pressure release automatically; the safety of protection pipeline; the backflow pressure retaining valve is located at the lime pump discharge, with lime access Calcified pond or the lime pump inlet that refluxes, has saved pipeline.
The above is only the preferred embodiment of the present invention, should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also make some improvement, and these improvement also should be considered as protection scope of the present invention.
