Abstract
The utility model discloses a measuring and fixing device for fruit and vegetable respiratory intensity, which comprises a respiratory chamber (3), purification bottles, an absorption bottle (4), a safety bottle (5) and an air sampler (6); the respiratory chamber (3) is sequentially connected with the absorption bottle, the safety bottle and the air sampler via a vent pipe; a fixing ring (7) is arranged outside the respiratory chamber; two adjustable metal clips (8) are arranged on the ring; the purification bottle I (1) and the purification bottle II (2) are respectively fixed on the two adjustable metal clips; and the respiratory chamber is connected with the purification bottle I (1) and the purification bottle II (2) via a vent pipe. According to the measuring and fixing device for fruit and vegetable respiratory intensity, two purification bottles can be fixed; concentrated alkali solution can be prevented from overflowing as the bottles are knocked down by a student accidentally; security of the experiment is improved; space is saved; air tightness is good; and the installation is simple.
Description
Technical field
The utility model relates to a kind of teaching aid, is that a kind of fruits and vegetables respiratory intensity is measured stationary installation specifically, is mainly used in fruits and vegetables respiratory intensity determination experiment in fruit and vegetable storage and transportation course.
Background technology
Fruits and vegetables respiratory intensity measure be fruit and vegetable storage and transportation learn must open experiment, the device adopting comprises two purification bottles, a respiratory chamber, an absorption tube, a safety flack and an air sampler.All devices are connected with rubber tube by glass tube, do not have at present stationary installation to be fixed.
Mainly there is following problem in this device at present:
(1) insecurity.Purification bottle is mainly to remove airborne CO
2, conventionally in purification bottle II, all hold concentrated alkali solution, if encounter because of carelessness the sebific duct of connection in operating process, just easily purification bottle to be dragged down, skin is encountered in high alkali liquid outflow or clothes can cause corrosion, abnormally dangerous.
(2) take up room greatly.When carrying out student experimenting, number of student is more, needs many groups equipment, but that whole respiration measuring device takes up space is larger, and a covering device area occupied is for being about 120 Х 50cm
2so experiment is subject to the restriction in place, often a plurality of students, with a determinator, are unfavorable for each students experimental implementation.
(3) easily gas leakage.Unstable for avoiding making purification bottle place because ventilating glue tube is too short, sebific duct is often longer, and sebific duct frequently connection can cause gas leakage, causes the failure of an experiment.
(4) be difficult for integrated moving.Whole device is connected by sebific duct by a plurality of parts, can not integrated moving, in mensuration process as while need adjusting, need a plurality of classmates to take respectively various piece, mutually coordinate to move, coordinate badly just to there will be sebific duct to drag the problems such as concentrated alkali solution outflow in de-, purification bottle.
(5) connect complexity.Owing to there is no stationary installation, before mensuration, scattered device to be assembled into a whole set of, very difficult for the student of first contact, often there is assembled mistake, cause normally moving, or cause the damage of sensing equipment.
Summary of the invention
The purpose of this utility model is to provide a kind of fruits and vegetables respiratory intensity to measure stationary installation, it can improve experimental implementation security, take up space little, and can holding device good impermeability, install simple easy operating can integrated moving, be conducive to student experimenting and obtain good result.
The technical solution of the utility model is as follows:
A kind of fruits and vegetables respiratory intensity is measured stationary installation, it consists of respiratory chamber, purification bottle, absorption bottle, safety flack, air sampler, respiratory chamber connects absorption bottle, safety flack, air sampler successively with snorkel, at above-mentioned respiratory chamber peripheral hardware set collar, on this ring, establish two adjustable metal folders, it is upper that purification bottle I and purification bottle II are separately fixed at above-mentioned two adjustable metals folder, and respiratory chamber connects purification bottle I and purification bottle II with snorkel.
The snorkel that above-mentioned respiratory chamber connects purification bottle I and purification bottle II is glass tube.
The utility model has the advantage of: (1) improves the security of experiment.Stationary installation can be fixed two purification bottles, avoids student to encounter because of carelessness, and concentrated alkali solution overflows, and guarantees the security of student experimenting.
(2) conserve space.Stationary installation combines scattered parts, has reduced the space taking, whole device take up space be about that original device takes up space 1/3, same experimental site can increase by 3 times of device quantity, for student provides more manipulator meeting.
(3) impermeability is good.Because the short pipeline of its connection rubber tube that makes of space length at each position of device is shorter, be conducive to keep the impermeability of whole device, part is more stable with glass tube.
(4) can integrated moving.Stationary installation can integrated moving, and a classmate just can move whole device, and needs a plurality of classmates' common coordination to move before not needing to look like to fix.
(5) install simply.So because as long as stationary installation is fixing fixing as required by the position of scattered parts, install very simple, quick.
(6) with low cost.The basic comprising of stationary installation is simple, and cost is low, easily makes.
Accompanying drawing explanation
Fig. 1 is existing fruits and vegetables respiratory intensity assay device structures schematic diagram;
Fig. 2 is the utility model example structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In Fig. 1～2,1, purification bottle I; 2, purification bottle II; 3, respiratory chamber; 4, absorption bottle; 5, safety flack; 6, air sampler; 7, set collar; 8, adjustable metal folder; 9, glass tube.
Fig. 1 is existing apparatus, and each several part connects with flexible pipe, there is no stationary installation.
By Fig. 2, can see structure of the present utility model, it is by respiratory chamber (3), purification bottle I (1); Purification bottle II (2), set collar (7), absorption bottle (4), safety flack (5), air sampler (6) form, between each container, with flexible pipe and glass tube (9), be communicated with, at above-mentioned respiratory chamber peripheral hardware set collar (7), on this ring, establish two adjustable metal folders (8), above-mentioned two purification bottles are separately fixed on above-mentioned two adjustable metals folders (8).
