Abstract
A river crab culture pond water quality detection sample water filtering device comprises a filtering cylinder, a lower end cap and an upper end cap. A three-filtering structure formed by an upper filter screen sheet, an upper spacer, a lower filter screen sheet and a lower spacer is arranged in the filtering cylinder. The lower end cap and the upper end cap are fixed to the two ends of the filtering cylinder in a sealed and rotary mode. A water inlet is communicated with a second-stage filtering cavity, and a water outlet is communicated with a pure water cavity. Sample water enters the filtering cylinder from the water inlet and then is conveyed to a corresponding chemical index analysis instrument from the water outlet after rough impurity filtering of the lower spacer, fine impurity filtering of the lower filter screen sheet and micro impurity filtering of the upper filter screen sheet. The filtering device can effectively filter out young snails, weeds and particle large impurities in water, can filter out alga and other suspended impurities in water, can effectively filter out fine sand particles contained in water, guarantees the cleanliness of water entering the chemical index analysis instrument, and accordingly guarantees accuracy of water quality detection. By means of a split body combined structure, the filtering device can be conveniently detached and cleaned periodically and can be repeatedly used.
Description
Technical field:
The present invention relates to aquaculture technology, particularly relate to a kind of water filtering device for river crab culture pond water quality detection.
Background technology:
Water temperature in culture of Chinese mitten crab process, dissolved oxygen, pH, ammonia nitrogen, nitrite, total phosphorus, total nitrogen and permanganate eight water quality index are to river crab survival rate, the speed of growth and quality all have a direct impact, in order to promote the technicalization administrative skill of aquaculture, improve the economic benefit at aquaculture family, applicant develops aquaculture water quality key index Internet of Things on-line monitoring for culture of Chinese mitten crab, process and managing and control system, comprising the online survey of physical index and the on-line checkingi of chemically index, described physical index refers to water temperature, dissolved oxygen and pH value three norms, chemically index refers to ammonia nitrogen, nitrite, permanganate, total phosphorus and the large index of total nitrogen five, applicant adopts Internet of Things+culture of Chinese mitten crab technology, develop river crab cultivation pond water quality on-line checkingi and Internet of Things managing and control system, it has water quality monitoring, video monitoring, production management, the comprehensive function such as SMS notification and Long-distance Control, Real-Time Monitoring is carried out to the water quality of river crab culture pond, wireless transmission, focus on and wireless report, 24 hours Monitoring and forecasting system in real-times can be carried out to water quality, reach " with foresight " and scientific and reasonable arrangement crabs production, for culture of Chinese mitten crab family provides real-time technological guidance, effective raising culture of Chinese mitten crab output and benefit.
It is reported, this system is the aquatic products Internet of things system that domestic current Testing index is the most complete, intelligent level is the highest, can Real-Time Monitoring temperature, dissolved oxygen, pH, ammonia nitrogen, nitrite, permanganate, total phosphorus and total nitrogen 8 water quality index, precision can reach less than 1%, and can carry out real-time and the inquiry of historical data, data and curves drafting etc.
In said system, chemically Indexs measure is carried out to pond water quality the sample water in pond to be checked must be synchronously synchronously provided to 5 chemical index analyzers, if deposit impurity in sample water, not only supply channel can be blocked, cause the obstruction of whole supply channel or bye-pass, chemical index synchronous analyzers in whole system can not synchronously be detected, but also can chemical analysis results be affected, therefore can ensure that the cleannes of the water entering chemical index analyzer are the key technology requirements guaranteeing that can whole system normally be run, in the actual motion of native system, often occur that 5 chemical index analyzers can not normally provide detection data, or the data registration provided is low, namely the precision fluctuation detected is large, we can not find reason in a long time, through long-term test, find after observation and analysis, its main cause is containing uncertain impurity in the sample water of synchronous supply, applicant is for a kind of water filter of hydrochemistry Indexs measure Design of Waterworks of river crab cultivation pond for this reason.
Summary of the invention:
The object of this invention is to provide a kind of river crab culture pond water quality detection sample water filtering device.
The technical solution adopted in the present invention is:
A kind of river crab culture pond water quality detection sample water filtering device, it is characterized in that: comprise filtration barrel body, bottom end cover, upper end cover, upper filter screen sheet, upper spacer, lower filter screen sheet and lower spacer, water inlet is axially arranged with along filtration barrel body, filter screen chamber, water-purifying cavity and delivery port, upper end cover is rotated with the upper end at filtration barrel body hermetically, upper filter screen sheet, upper spacer, lower filter screen sheet and lower spacer are sleeved in filter screen chamber from top to bottom successively, the height section that the surrounding sidewall of lower spacer corresponds to water inlet is provided with inlet opening equably, bottom end cover is rotated with the lower end at filtration barrel body hermetically, upper filter screen sheet, upper spacer, filter screen chamber is divided into primary filter chamber and cascade filtration chamber by lower filter screen sheet and lower spacer, water inlet and primary filter chamber interlink, delivery port and water-purifying cavity interlink, upper end cover is rotated with the upper end at filtration barrel body hermetically.
Further, lower spacer is provided with the diameter of inlet opening is 0.5 ~ 3 millimeter.
Further, the order number of upper filter screen sheet is greater than the order number of lower filter screen sheet.
Further, upper spacer, lower filter screen sheet and lower spacer are connected as a single entity, and form the cartridge structure of dual-end.
Work principle of filter is: the press water in water inlet manifold enters from water inlet, then filters through the thick assorted of lower spacer successively, then filters through the thin assorted of lower filter screen sheet, flows to corresponding chemical index analyzer finally by after the micro-assorted filtration of upper filter screen sheet from delivery port.
The sample water extracted out from pond to be detected like this have passed three roads and filters, can not only young spiral shell effectively in filtering water, weeds and a shape coarse impurities, and can the suspended impurity such as algae in filtering water, simultaneously can effectively filtering to trickle of the silt contained in water, ensure that the water cleannes entering chemical index analyzer, thus ensure the accuracy of water quality detection.
Owing to present invention employs Split assembled structure, be convenient to timing disassembly, cleaning, reusable.
