Abstract

The utility model relates to a pickler for filter cloth of a press filter, which comprises a press filter body and filter plates, wherein the filter plate is provided with the filter cloth; a feeding pipeline of the press filter body is connected with an acid feeding pipeline which is provided with a valve; the tail end of the press filter body is connected with an acid discharging pipeline; the acid feeding pipeline and the acid discharging pipeline are connected with a hydrochloric acid tank; the acid feeding pipeline is provided with a high-pressure pump; and the tail end of the press filter body is further provided with a gas exhaust port. By the steps of modifying the feeding pipeline of the press filter, connecting the acid feeding pipeline on the feeding pipeline, closing a feeding valve of the feeding pipeline and then opening the valve of the acid feeding pipeline, hydrochloric acid is pumped into the press filter body by the high-pressure pump, and is added among all the filter plates of the press filter body so as to carry out continuous pickling on the filter cloth which does not need to be dismantled and mantled, and the continuous pickling of the filter cloth can be completed conveniently and directly in the press filter body, therefore, on one hand, the workload of operators is reduced, and the working hour is saved, on the other hand, manual pickling is not needed, and the safety coefficient is high.

Description

The acid dip pickle of canvas press cloth
Technical field
The utility model relates to a kind of acid dip pickle of canvas press cloth, belongs to chemical field.
Background technology
Because the chlorine method of purification is produced expoxy propane and is produced a large amount of waste water, contains a large amount of calcium hydroxide in the waste water, need filter out filter cake, enters biochemical treatment; In filter process, just need a large amount of filter clothes, canvas press cloth is after using, the filter cloth surface will produce calcium hydroxide, calcium carbonate scaling, cause the filter cloth water penetration to reduce, cause filter press to press the emplaster water content big, influence the filter cake outward appearance, therefore will change canvas press cloth, because filter cloth filters frequent, use amount is big, in order to save filter cloth, need utilize the acid-base neutralization reaction, filter cloth is placed on soaks processing in 24 hours in the hydrochloric acid, carry out rinsing with a large amount of clear water afterwards, at last filter cloth is dried standby, the life cycle that prolongs filter cloth in this way, but this process is entirely manual operations, and this process filter cloth will be torn open, dress each 1 time, personnel's workload is big, the labour intensity height, and in pickling (hydrochloric acid) process, need to use hydrochloric acid, the danger coefficient height.
Summary of the invention
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of staff of reduction labour intensity, save the working time, the acid dip pickle of canvas press cloth that safety coefficient is high, do not need the dismounting filter cloth can finish filter cloth pickling work.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of acid dip pickle of canvas press cloth, comprise filter press body and filter plate, filter cloth is housed on the filter plate, it is characterized in that: connect the acid inlet tube line on the feeding line of filter press body, mounted valve on the acid inlet tube line, the terminal acid discharge pipeline that connects of filter press body, the acid inlet tube line all is connected hydrochloric acid tank with the acid discharge pipeline, on the acid inlet tube line high-pressure pump is set, filter press body end also is provided with exhaust outlet.
Operation principle and process:
When needing to clean the filter cloth in the filter press body, close the inlet valve on the feeding line earlier, open the valve of acid inlet tube line, can hydrochloric acid be beaten to filter press, between each filter plate of filter press body, add hydrochloric acid and use by high-pressure pump, like this without the demolition, installation filter cloth, directly can conveniently finish the serialization pickling of filter cloth, thereby greatly reduce operating personnel's workload, save the working time in filter press body inside, and need not the manual pickling of people, safety coefficient height.Air when the acid-base neutralization course of reaction produces carbon dioxide and pickling between filter plate can all in time be discharged from the exhaust outlet of filter press body end.Hydrochloric acid behind the pickling filter cloth is sent hydrochloric acid tank again back to, in order to repeatedly recycling.
The beneficial effect that the utility model had is: the acid dip pickle that a kind of canvas press cloth is provided, by transforming the feeding line of filter press, on the feeding line of filter press body, connect the acid inlet tube line, close the inlet valve of feeding line, open the valve of acid inlet tube line again, can hydrochloric acid be beaten to the filter press body by high-pressure pump, adding hydrochloric acid between each filter plate of filter press body uses, filter cloth is carried out the serialization pickling to be used, and need not tear open, the dress filter cloth, directly can conveniently finish the serialization pickling of filter cloth in filter press body inside, greatly reduce operating personnel's workload on the one hand, save the working time, need not the manual pickling of people on the other hand, the safety coefficient height.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, feeding line; 2, inlet valve; 3, filter press body; 4, filter plate; 5, acid discharge pipeline; 6, hydrochloric acid tank; 7, exhaust outlet; 8, high-pressure pump; 9, acid inlet tube line; 10, valve
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, the acid dip pickle of canvas press cloth comprises filter press body 3 and filter plate 4, on the filter plate 4 filter cloth is housed, connect acid inlet tube line 9 on the feeding line 1 of filter press body 3, mounted valve 10 on the acid inlet tube line 9, the filter press body 3 terminal acid discharge pipelines 5 that connect, and acid inlet tube line 9 all is connected hydrochloric acid tank 6 with acid discharge pipeline 5, high-pressure pump 8 is set on the acid inlet tube line 1, and filter press body 3 ends also are provided with exhaust outlet 7.
Operation principle and process:
When needing to clean the filter cloth in the filter press body 3, close the inlet valve 2 on the feeding line 1 earlier, open the valve 10 of acid inlet tube line 1, can hydrochloric acid be beaten to filter press body 3 by high-pressure pump 8, adding hydrochloric acid to filter press body 34 of each filter plates uses, like this without the demolition, installation filter cloth, directly can conveniently finish the serialization pickling of filter cloth in filter press body 3 inside, thereby greatly reduce operating personnel's workload, saved the working time, and need not the manual pickling of people, safety coefficient height.The air of 4 of filter plates can all in time be discharged from the exhaust outlet 7 of filter press body 3 ends when the acid-base neutralization course of reaction produced carbon dioxide and pickling.Hydrochloric acid behind the pickling filter cloth is sent hydrochloric acid tank 6 again back to, in order to repeatedly recycling.
