The technical scheme that the utility model solves above technical matters is: a kind of overflow-type automatic control sampler, comprise sampling groove, COD monitoring device and at least 1 stopple coupon, described stopple coupon is communicated with described sampling groove, described sampling groove is communicated with described COD monitoring device, described sampling groove bottom arranges leak-off pipe, the diameter of described leak-off pipe is less than the diameter of described stopple coupon, and, on the sidewall of described sampling groove, overflow vent is set.
Being further defined to of technical solutions of the utility model, the diameter of described leak-off pipe is 1/2 ~ 2/3 with the diameter of described stopple coupon ratio.
Further, also comprise PLC central controller, a sample valve is set on each stopple coupon, between described sampling groove and described COD monitoring device, a sampling pump is set, described PLC central controller and described sample valve and the communication connection of described sampling pump.
Further, also comprise run-down pipe and blow-off pipe, the water inlet of described run-down pipe is fixedly installed on the overflow vent of described sampling groove, and its water delivering orifice is communicated with the water inlet of described blow-off pipe.
Further, the water delivering orifice of described leak-off pipe and the water inlet of described blow-off pipe are communicated with.
Further, on described leak-off pipe, venting valve is set.
Further, the bottom of described sampling groove is taper.
The beneficial effects of the utility model are: a kind of overflow-type automatic control sampler that the utility model provides, and water inlet, overflow, earial drainage carry out simultaneously, avoid the mutual pollution between water sample, it is more accurate to sample, and sampling groove is conical bottom, avoids the accumulation of the suspensions such as mud; Of the present utility model simple in structure, transformation easily, cost-saving, easy to use.
Brief description of the drawings
The structural representation of the overflow-type automatic control sampler that Fig. 1 provides for the utility model.
Embodiment
embodiment 1
The present embodiment discloses a kind of overflow-type automatic control sampler, its structural representation as shown in Figure 1, comprise sampling groove 3, COD monitoring device 5, PLC central controller 1 and at least 1 stopple coupon 2, tell about creation point of the present utility model for more convenient, the quantity of the stopple coupon 2 of the present embodiment is 3.
Acting as of stopple coupon 2 obtains water sample, and its water inlet end is communicated with water sample pond, and its water side is communicated with sampling groove 3, and the water in water sample pond is imported in sampling groove 3.In order to control the work of stopple coupon 2, a sample valve 4 is set on each stopple coupon 2, and sample valve 4 communicates to connect with PLC central controller 1, by the program of implanting in advance in PLC central controller 1, automatically control the open and close of 3 sample valves 4, thus automatic acquisition water sample.
Sampling groove 3 act as interim storage water sample, its bottom arranges leak-off pipe 8, on the sidewall of top, overflow vent is set, and, the diameter of leak-off pipe 8 is less than the diameter of described stopple coupon 2, conventionally, the diameter of leak-off pipe 8 is 1/2 ~ 2/3 with the diameter ratio of stopple coupon 2, when stopple coupon 2 is intake sample, leak-off pipe 8 flows out water sample, ensures that the water level in sampling groove 3 can rise to overflow vent simultaneously, more than water sample overflow through overflow vent, can rinse the sidewall of sampling groove 3, guarantee not polluted by previous water sample.And the bottom design of sampling groove 3 is taper, avoid the suspension accumulation such as mud.
In order to collect the water sample overflowing, the present embodiment is also provided with run-down pipe 9 and blow-off pipe 10, and the water inlet of run-down pipe 9 is fixedly installed on the overflow vent of sampling groove 3, and its water delivering orifice is communicated with the water inlet of blow-off pipe 10, meanwhile, the water delivering orifice of leak-off pipe 8 is communicated with the water inlet of blow-off pipe 10.In addition, in order to keep the leakproofness of sampling groove 3 in the time that device does not use, venting valve 7 is set on leak-off pipe 8, in the time that device does not use, closes venting valve 7.
COD monitoring device 5 is used for water sample to detect, its water inlet is communicated with sampling groove 3, between sampling groove 3 and described COD monitoring device 5, a sampling pump 6 is set, PLC central controller 1 communicates to connect with sample valve 4 and sampling pump 6, by the program of implanting in advance in PLC central controller 1, automatically control the duty of sampling pump 6.
The control that the control program of implanting in PLC central controller 1 relates to Timing Processing and sequential realizes in existing automatic control sampler, in the present embodiment, is not repeating.
When a kind of overflow-type automatic control sampler that the utility model provides is worked, PLC central controller 1 is controlled the sample valve 4 of the first stopple coupon and is opened, venting valve 7 is opened, and the water sample in the first stopple coupon injects sampling groove 3, and especially the diameter of leak-off pipe 8 is less than the diameter of stopple coupon 2, therefore, water level in sampling groove 3 rises, full rear overflow, the process of whole water filling overflow, clean sampling groove 3, guaranteed not the water sample residual contamination by above.PLC central controller 1 is controlled sampling pump 6 and is started, and water sampling detects to COD monitoring device 5.After sampling, PLC central controller 1 cuts out the sample valve 4 of the first stopple coupon, after the interior current of sampling groove 3 are emptying, open the sample valve 4 of the second stopple coupon, water inlet sample is to sampling groove 3, repeat above-mentioned action, sampling detects, and sequence detection water sample successively, after treating that water sample all detects, PLC central controller 1 cuts out venting valve 7, completes sampling and detects.
As mentioned above, although represented and explained the utility model with reference to specific preferred embodiment, it shall not be construed as the restriction to the utility model self.Not departing under the spirit and scope prerequisite of the present utility model of claims definition, can make in the form and details various variations to it.
