The utility model relates to a box for raising animals, particularly a constant temp. and humidity clean box for raising two-pole and three-pole experimental animals. A surface cooler is arranged on the opening of the lower baffle plate of the air channel of a box body, a blower is supported on the outer side wall of an upper channel of the upper baffle plate of the box body, and the lower part of the air channel of the blower is connected and dropped to the circulating air channel of the lower baffle plate of the box body. A raising cabinet is a vertical multi-grid cabinet composed of a cabinet frame with inner through holes, the cabinet frame is provided with a slotted air outlet on the front end of each grid chamber, and therefore, the box for raising the animals can obtain air with proper humidity and temperature in the humid environment of the summer so as to improve the raising environment and be favorable for the growth of the animals.

Description

Constant temp. and humidity clean box for animals raising

The utility model relates to a kind of letting animals feed cabinet, especially raises secondary and three utmost point laboratory animal.

At present, common raising experiment makes it keep suitable temperature, humidity and clean air with possessing temperature adjustment, humidification and air cleaning unit in the cattle container, and still, be not suitable for laboratory animal towards wet air summer.

In view of this, the purpose of this utility model provides the clean animal feeding case of a kind of constant temperature and humidity, increasing humidity at existing warmer, can be by surface cooler with the air of blower fan shunting also, makes the little air quantity pure air that obtains suitable temperature and temperature in the animal feeding cabinet.

The purpose of this utility model is achieved in that the clean cattle container of constant temperature constant temperature comprises casing, filter, humidifier, heater, blower fan and raises cabinet, on the lower clapboard hole of casing wind passage, be provided with surface cooler, blower fan is supported on the casing upper spacer on the square channel lateral wall, and the air channel of blower fan below connects the circulation air path that hangs down into below the casing lower clapboard, raising cabinet is the vertical many lattice cabinet with framework composition of inner via hole, and this tank bracket is provided with bar seam air outlet at each lattice chamber front end.Above-mentioned surface cooler has seven row's evaporation tubes.The air intake of above-mentioned circulation air path is provided with a control valve.

Owing to adopt such scheme: in the summer wet environment, also can obtain the air of suitable temperature in the letting animals feed case, improve the environment of raising, help the growth of animal.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model exemplary embodiments structural representation.

Among the figure: 1, casing 11, wind passage 111, lower clapboard 112, upper spacer 12, empty chamber 13, base plate 2, low efficient filter 3, medium effeciency filter 4, high efficiency particulate air filter 5, humidifier 6, surface cooler 7, heater 8, blower fan 81, air channel 82, circulation air path 83, control valve 84, air delivery duct 9, raise cabinet 91, framework 92, lattice chamber 921, bar seam air outlet 922, transparent doors

Casing 1 is divided into wind passage 11, empty chamber 12 and base plate 13 3 parts, lower clapboard 111 that has and upper spacer 112 in wind passage 11.

Humidifier 5 is arranged on wind passage 11 inner bottom platings 13 of casing 1, and a low efficient filter 2(multi-layer fiber layer is set at a lateral wall place of opening of casing 1 wind passage 11), the particulate in the filtered air.

Surface cooler 6 is the equipment by the dehumidifying big (enthalpy difference is big) of many rows (seven rows) evaporation tube (interior dress liquid fluorine) and heat-conducting plate (aluminium case) combination, satisfy immature laboratory animal in moist summer, reduce the requirement (surface cooler of 4 row's evaporation tubes commonly used belongs to prior art) of temperature, this surface cooler 6 is supported in above the accent mouth of lower clapboard 111 in the humidifier 5 top wind passages 11.Heater 7(electric heater belongs to prior art) be supported on the sidewall of square box 1 wind passage 11 on the surface cooler 6.Medium effeciency filter 3(multi-layer fiber layer) above the hole of equipment upper spacer 112 of square box 1 wind passage 11 on heater 7, it is little specific filtration resistance slightly to imitate filter 2 filtered air particulates.

750 cubic metres/hour of blower fan 8(centrifugal blower capacity) be supported on the lateral wall of square box 1 wind passage 11 on the medium effeciency filter 3 (left side wall), outlet at blower fan 8, be communicated with air channel 81 to the right, these air channel 81 outlets are connected on the madial wall hole (right side wall), connect high efficiency particulate air filter 4 in this left side, madial wall hole of casing 1 again, energy specific filtration resistance effect filter 3 filtered air particulates are little, connect each air delivery duct 84 of leading in the sky chamber 12 and raising cabinet 9 then, below air channel 81, connect the circulation air path 82 hang down into below the lower clapboard 111 again, these circulation air path 82 air inlets also are provided with a control valve 83, regulate air channel 81 discharge quantities of fan and air circulation, make the air quantity of circulation pass surface cooler 6 again, electric heater 7, medium effeciency filter 3 enters the air inlet (inlet scoop) of blower fan 8, keep on the one hand to raise in the cabinet 9 and be in little air quantity environment, be suitable for the growth of immature laboratory animal, increase the air quantity of circulation on the other hand, can pass big enthalpy difference surface cooler 6, make and raise the air that obtains again in the cabinet 9 through dehumidifying, satisfy moist summer immature laboratory animal the requirement of temperature.

Raising cabinet 9 is by tank bracket 91, the transparent doors 922 of a plurality of lattice chamber 92 and each chamber, lattice chamber constitutes many lattice of vertical type cabinet, this raising cabinet 9 places on the base plate 13 at 12 places, casing empty chamber 1, air delivery duct 84 is communicated with the inner via hole of tank bracket 91, end frame 91 has bar seam air outlet 921 before each lattice chamber 92, the wind of sending into dispersion is to each lattice chamber, and in addition, each lattice chamber rear wall also is provided with exhaust outlet.

The ventilation process of present embodiment is as follows:

During dry cold season (winter), under the effect of blower fan 8, outside air enters low efficient filter 2, through humidifier 5 humidifying airs, passing surface cooler 6(group surface cooler does not start) slit between pipe, heater via 7 adds hot-air, again through medium effeciency filter 3 filtration, purification air, enter blower fan 8 air inlets, a part of air quantity (keeping little air quantity) through the air channel 81, high efficiency particulate air filter 4, air delivery duct 84, enter tank bracket 91 inner via holes of raising cabinet 9, bar seam air outlet 921 is discharged from lattice chamber exhaust outlet at last to lattice chamber 92; Another part air quantity but enters control valve 83, circulation air path 82, enters down below 111, repeats said process, up to entering lattice chamber 92.

During moist hot season (summer), under the effect of blower fan 8, outside air enters low efficient filter 2, does not start through surface cooler 6(warmer this moment), (this moment, whether heater started according to the temperature decision of dehumidifying back air to make air dewetting.Through medium effeciency filter 3 filtration, purification air, enter blower fan 8 air inlets, below the process of process during with dry cold season identical, so do not repeat.

In sum, no matter the utility model is dry cold winter, still all can guarantee to raise in-cabinet temperature at 18-28 ℃ moist hot summer, relative temperature 40%-70%, and be in little air quantity (below 500 cubic metres/hour), enthalpy difference big (8 kilocalorie/kilograms are following), the air-supply cleanliness factor reaches aseptic environments.
