When three-way valve 17 is switched to the first connecting pipe 5 and is communicated with plain boiled water circulating line 7, clear water or plain boiled water are from the first connecting pipe 5 via three-way valve 17, plain boiled water circulating line 7 and stainless steel trough 8.
Overflow pipe 9, drainage pipeline 10, main sewer 11 form three-way pipe by three-way connection 18.
Specifically, one end of overflow pipe 9 is communicated with stainless steel trough 8, and the other end is communicated with the junction of drainage pipeline 10 and main sewer 11.One end of drainage pipeline 10 is communicated with overflow pipe 9 and main sewer 11, and the other end is communicated with stainless steel trough 8.At drainage pipeline 10, be provided with draining hand valve 14d midway.One end of main sewer 11 is communicated with overflow pipe 9 and drainage pipeline 10, and the other end directly discharges to trench.
Between water pump P and stainless steel trough 8, by the second connecting pipe 12, be communicated with.
By above-mentioned draining hand valve 14d, make plain boiled water recycle or be directly expelled to trench.
By above-mentioned overflow pipe 9, plain boiled water too much in tank 8 is expelled to trench.
At three-way valve 17, being switched to the first connecting pipe 5 is communicated with clear water/plain boiled water inlet channel 6, draining valve is controlled as to be opened, and in the situation that draining hand valve 14d closes, enter in paper former 1, and the water after circulation is therein expelled to tank 8, under the suction of the water pump P being driven by motor M, plain boiled water in tank 8 is got to plain boiled water inlet channel 4 via the second connecting pipe 12, and then circulation in plain boiled water inlet channel 4, the first connecting pipe 5, clear water/plain boiled water inlet channel 6, tank 8, the second connecting pipe 12.
At three-way valve 17, being switched to the first connecting pipe 5 is communicated with plain boiled water circulating line 7, and in the situation that draining hand valve 14d closes, plain boiled water enters tank 8 by three-way valve 17 via plain boiled water circulating line 7, under the suction of the water pump P being driven by motor M, plain boiled water in tank 8 is got to plain boiled water inlet channel 4 via the second connecting pipe 12, and then circulation in plain boiled water inlet channel 4, the first connecting pipe 5, plain boiled water circulating line 7, tank 8, the second connecting pipe 12, use by this plain boiled water to wash away above-mentioned pipeline, to avoid having precipitation in tank.
When draining hand valve 14d opens, the water in tank 8 just can discharge to trench via drainage pipeline 10 and overflow pipe 9.
Thus, plain boiled water inlet channel 4, the first connecting pipe 5, clear water/plain boiled water inlet channel 6, paper former 1, tank 8, the second connecting pipe 12 connects successively and form up plain boiled water circulation (as shown in Figure 1), and plain boiled water inlet channel 4, the first connecting pipe 5, plain boiled water circulating line 7, tank 8, the second connecting pipe 12 connects successively and form descending plain boiled water circulation (as shown in Figure 2).
By forming as mentioned above, function and the plain boiled water circulatory function can with single water supply in original handsheet process, handsheet, draining simultaneously, by this, the requirement of experiment that can meet ISO/Tappi standard code, improve plain boiled water reclamation rate, reduce unnecessary plain boiled water discharge, and be unlikely, environment is caused to serious pollution.
Those of ordinary skill in the art are easy to expect other advantage and modification.Therefore, its more wide in range aspect on, shown in the utility model is not limited to here and described detail and exemplary embodiment.Therefore, can under the prerequisite of spirit or scope that does not depart from the overall inventive concept of basis limiting as appended claims and equivalent thereof, make various modifications.
For example, in the present embodiment, on drainage pipeline 10, be only provided with draining hand valve 14d, but also can between draining hand valve 14d and tank 8, check valve be set, and make check valve be arranged to allow plain boiled water via drainage pipeline 10, to enter main sewer 11 from tank 8, and do not allow plain boiled water to reflux, by this, can avoid plain boiled water cannot drain in tank and cause precipitation.In addition, also can on main sewer 11, check valve be set.
For example, in the present embodiment, tank 8 is stainless steel troughs, but the utility model is not limited to this, so long as the material that is not easy to be corroded by plain boiled water, tank 8 can be formed by any material.
