Abstract
The utility model is an industrial sewage sampling device, which relates to a novel sewage sampling device. After the sewage enters a container through a dust gauze, the sewage enters an analytical instrument from a sample introduction port. The mechanism comprises the following parts: an external container, wherein a sewage inlet is arranged at the bottom of the external container, a flooding pipe is arranged in the middle of the external container, and the sample introduction port which is connected with a water sample analytical instrument and an air inlet which is connected with a compressed air pump are arranged on an upper port of the external container; an inner pipe, which is arranged inside the external container, wherein the upside of the inner pipe is communicated with the air inlet, and the bottom is connected with the dust gauze. A sample pipe is inserted and connected in the middle of the inner pipe. One end of the sample pipe is communicated with the sample introduction port, and the other end extends to the dust gauze. In the sampling interval time, the compressed air pump is started, and the impurities on the dust gauze are blown out from the air inlet through an air blowing opening. The impurities are carried off by continuous flowing sewage which is between the sewage inlet and a leakage fluid dram. A sampling pump and the compressed air pump act alternatively, thereby greatly reducing the change of the dust gauze and cleaning cycles, and reducing the fault rate of the analytical instrument for sampling.
Description
Technical field
The utility model relates to a kind of new sewage sampler, can effectively reduce the cleaning of screen pack and change number of times, avoids losing efficacy because of the analytical instrument of water quality that screen pack stops up fully or the sample introduction underfed causes, and refers in particular to a kind of industrial sewage sampler.
Background technology
At present, general industrial sewage sampler adopts static simple filtration net to stop impurity a large amount of in the sample introduction sewage.Usually use the short time, just must clean or change screen pack.Adopting the cascade filtration net is the scheme of using always, but its first order still is very easy to stop up.
In order to solve top problem, the utility model proposes a kind of new technical scheme.

When industrial sewage enters container by screen pack, and after stopple coupon enters analytical instrument, sampling pump quits work, the pressurized air pump work, pressurized air carries out from inside to outside counterflush by air intake opening to screen pack, the impurity that is attached to the screen pack outside is blown off, before guaranteeing each sample introduction, the screen pack outside does not have impurity to adhere to, thereby guarantees that water sample enters analytical instrument.
The processing of external container for convenience, on the such scheme basis, described injection port and air intake opening are located on the locking bottle cap, and the external container upper port is provided with an external thread interface, and locking bottle cap spiral is connected on the external thread interface.
Described locking bottle cap can be made of lid that injection port and air intake opening are set and pressure ring, and lid is provided with chimb, and pressure ring is provided with internal thread, and pressure ring is pushed down the lid chimb and is connected with external thread interface spiral.Make the simple in structure of container cover, easy to assembly.
In order to increase filter area, described screen pack is a tubular structure.
Described screen pack is that stainless steel filters webmaster, and the bottom is airtight, the lower end of pipe in top one hickey, spiral are connected.
On the such scheme basis, described screen pack is fixed on the sample introduction pipe end cap, and described sample introduction pipe end cap bottom is provided with sealing, is evenly equipped with the inflatable mouth to four limits in the sealing upper end, and top has a threaded line pipe portion to be socketed in interior pipe bottom.When the pressurized air pump work, pressurized air blows to screen pack through interior pipe from inflatable mouth.
For easily manufactured, the connecting portion at the bottom of sample introduction pipe end cap and the interior pipe is provided with an adapter sleeve.
The beneficial effects of the utility model are: can guarantee that in this cycle device lifetime, the sewage sample can expeditely enter analytical instrument.The replacing of screen pack or cleaning frequency, by general about one month at present, bring up to about 1 year, significantly reduced the failure rate that analytical instrument can't sample introduction.
