Background technology
Usually use filter tunnel at aspects such as education and instruction, chemical analysis, sanitary inspection, petroleum industry, pharmaceuticals industry, dye industries and separate solidliquid mixture, sand core funnel and Buchner funnel are conventional filter tunnel instruments, Buchner funnel is a kind of ceramic instrument, also useful plastic production, is used for using vacuum or negative pressure suction to filter; Sand core funnel is that acid-resistant glass filters instrument, adopts good hard high boron glass composition, has higher physicochemical property.Filter tunnel all needs to carry out carrying out washing treatment after using, in order to avoid affect next filter efficacy because sediment stops up, filter tunnel has water conservancy diversion long-neck conventionally, is subject to the restriction of filter tunnel structure, cleans inconvenience and easily leaves dead angle.
China's patent (CN2897376) discloses a kind of easy cleaning suction funnel, comprise infundibular body, infundibular body top is rounding stage body, bottom is cylinder, be characterized in that Rotary-table and cylindrical junction are circular platform, circular platform and infundibular body are connected as a single entity, and have through hole on circular platform, and the lateral surface of infundibular body lower cylindrical body is with frosting.This suction funnel in use, is placed on filter paper above the circular platform of infundibular body, then the adapter that infundibular body is worn to frosting by an inner side directly inserts bottle,suction, filters or suction filtration.
Whole funnel is divided into two parts by the easy cleaning suction funnel that above-mentioned patent provides, can take apart to clean, but simple the pegging graft of this funnel is connected, gas sealing ability is not good, in the time that in funnel, liquid is more, easily overflows from the two-part connector of funnel, impact is normal to be used, in addition, two part socket connections of this funnel are firm not, the safety and reliability that impact is used.
Summary of the invention
The problems referred to above that the utility model exists for existing technology, provide a kind of split type filter tunnel, and technical problem to be solved in the utility model is: how can in facilitating filter tunnel to clean, ensure its sealing and fastness.
The purpose of this utility model can realize by following technical proposal:
A kind of split type filter tunnel, it is characterized in that, described filter tunnel comprises infundibular body and baffle, and described infundibular body is the tubular running through up and down, in described infundibular body, being installed with can be by the filter of Separation of Solid and Liquid, on the lateral wall of described infundibular body near lower end, is installed with external screw thread; Described baffle is the tubular that end face is uncovered, the bottom surface of described baffle is installed with water conservancy diversion neck down, described water conservancy diversion neck is the tubulose of hollow and is connected with described baffle inside, on the madial wall of described baffle near upper end, be installed with the internal thread that can match with described external screw thread, described infundibular body and described baffle bolt.
Its principle is as follows: this split type filter tunnel comprises infundibular body, three parts of baffle and water conservancy diversion neck, set gradually from top to bottom, infundibular body and baffle are spirally connected, water conservancy diversion neck is connected in baffle bottom, in infundibular body, there is filter, while using this split type filter tunnel, solid-state and liquid mixture is inserted in infundibular body, filter by filter, solid is stayed on the filter of infundibular body, liquid is by the filter baffle of flowing through, and flow out by water conservancy diversion neck, reach the object that solid-liquid filtration separates, the filter here both can have been used the filtration of sand core funnel, also can use the filtration of Buchner funnel.After using, need to clean this filter tunnel, because infundibular body and baffle are screwed together, can dismantle, both are separated, just can clean very easily, particularly the join domain of baffle and water conservancy diversion neck, can wipe after separation easily, does not stay dead angle.Infundibular body and the baffle employing mode that is spirally connected, the area of the internal thread contact area on external screw thread and baffle on infundibular body is large, can play better sealing effectiveness, while avoiding the interior liquid of baffle too much, overflow from junction, simultaneously both employings mode that is spirally connected is in use safe and reliable, can not come off.
In above-mentioned split type filter tunnel, described external screw thread lower end is also provided with sealing ring, and described sealing ring is set on the lateral wall of described infundibular body.The lateral wall of infundibular body lower end is provided with sealing ring, and when infundibular body and baffle bolt, sealing ring and baffle lean, and can play good sealing function, prevents that liquid in baffle or gas are excessive or leak from the gap of both junctions.
In above-mentioned split type filter tunnel, described sealing ring adopts polytetrafluoroethylene (PTFE) to make.Polytetrafluoroethylene (PTFE) has good chemical stability, corrosion resistance, is one of decay resistance optimal material in the world today, is widely used in the occasion of the antiacid alkali of various needs and organic solvent.Ageing resistance is strong, heatproof is excellent, and people is not had to toxicity, applies the sealing ring that this material makes and makes this filter tunnel applied widely, safe and reliable.
In above-mentioned split type filter tunnel, described internal thread and externally threaded surface are frosting.External screw thread and internal thread form frosted interface, can improve the airtight performance of junction, avoid liquid in baffle or gas excessive or leak from the gap of junction; Another the convenient stickup self-locking that also can avoid interface, is convenient to separating of infundibular body and baffle, facilitates follow-up cleaning.
In above-mentioned split type filter tunnel, the periphery of described filter and the madial wall of described infundibular body are connected, and offer some through holes on described filter.Filter is connected in infundibular body, and solid matter is intercepted, and liquid can flow out from through hole, plays the effect that separates solid-liquid material.
In above-mentioned split type filter tunnel, described filter and described infundibular body are one-body molded.One-body molded being convenient to processed, and structure is firm, saves production cost thereby save mould, enhances productivity.
In above-mentioned split type filter tunnel, described baffle and described infundibular body coaxially arrange, and the sidewall of described baffle and the sidewall of infundibular body are all the angle of 15 °-45 ° with vertical direction.Such angle of inclination facilitates flowing of material, and simultaneously baffle is connected with infundibular body and has guide effect, handled easily when separating.
In above-mentioned split type filter tunnel, the bottom surface of described baffle is from periphery to middle part towards having a down dip, and described water conservancy diversion neck is installed in the middle part, bottom surface of described baffle and coaxially arranges with described baffle.The material that the inclination gathering face forming is conducive in baffle is assembled and is concentrated to middle part, baffle bottom surface, and flows out by water conservancy diversion neck, and the outflow of material is thoroughly clean more fast, and convenient cleaning, saves material.
In above-mentioned split type filter tunnel, described infundibular body, baffle and water conservancy diversion neck all adopt high boron glass to make.High boron glass is the specific glass material of a kind of low thermal expansion, high temperature resistant, high strength, high rigidity, high transmission rate and high chemical stability, its acid resistance and alkaline resistance properties are better, the isolated by filtration that the split type filter tunnel made from it carries out chemicals is little to himself, long service life.
Compared with prior art, advantage of the present invention is as follows:
