Abstract

The present invention relates to a body-separated temperature and humidity meter capable of accurately reading out measured temp and humidify of another independent space in an independent space. Said device is formed from two temp-sensing bags, panel with temp and humidity scales, two glass capillary tubes, two metal capillary tubes, water kettle and cotton yarn. Said invention also provides their connection, mounting mode, and its application range.

Description

A kind of split type liquid Hygrothermograph

Affiliated technical field

Patent of the present invention is a kind of split type liquid Hygrothermograph, can read temperature, humidity in another separate space of being surveyed exactly a separate space, thereby improves labor productivity and baking properties.

Background technology

At present, the humiture of the dry process of China's Special Agriculture Product detects, and generally adopts the glass capillary liquid-filled thermometer.Be that thermometer is hung in the hothouse, thermometer must be drawn in the time of observing temperature near the window place.The dry indoor humidity of baking the early stage of drying is often bigger, and view window often has dewdrop and thickens, and observes unintelligible, dry indoor temperature very high (60-70 ℃) of middle and later periods, from the check point view window that furthers, variation has taken place in actual environment with thermometer, and temperature reading changes thereupon.So read untrue.Though advanced electronic thermometer can address this problem, cost is relatively costly, is difficult in the production accept.We both can read indoor temperature, humidity outdoor by the split type liquid Hygrothermograph of design, and with low cost.

Summary of the invention

In order to improve Special Agriculture Product production and dry processing quality, we have invented split type liquid Hygrothermograph, are used to show the actual humiture of production or processing environment.It is the expansion and contraction property that utilizes liquid, in dry Processing Room, hang temperature bulb and humidity bulb, kettle, cotton yarn, the liquid degree of expanding with heat and contract with cold in two bulb, be delivered to glass capillary by metal capillary respectively, the temperature and humidity (representing) in the indication hothouse with dry-bulb temperature and wet-bulb temperature.Adopt the heterogeneity that non-homogeneous scale expands with heat and contract with cold to metal and liquid and the compensation for calibrating errors of two temperature conduction pipe transmittance process differences.

Description of drawings

Below in conjunction with drawings and Examples patent of the present invention is described further.

(2) panel scale, (3) metal capillary, (4) bulb, (5) cotton yarn, (6) kettle.

(7) hothouse among Fig. 2, (8) heating arrangement, (9) heat-preserving wall, (10) roasted material

Embodiment

In principle wiring layout shown in Figure 1, hanging temperature bulb and humidity bulb (4), kettle (6) and cotton yarn (5) in dry Processing Room provides moisture for the humidity bulb, the liquid degree of expanding with heat and contract with cold in two bulb, be delivered to glass capillary (1) by metal capillary (3) respectively, temperature and humidity in the indication hothouse is read by panel scale (2).

In monitoring synoptic diagram shown in Figure 2, with humiture display panel (2) with comprise that glass capillary (1) is hung on outside the dry Processing Room, bulb (4) is drawn in indoor by the aperture of dry process equipment heat-preserving wall (9), be hung on the correct position that processing technology requires usually, and the cotton yarn (5) that bulb (4) is outer is filled in kettle (6), kettle (6) is hung on correct position, can outside dry process equipment heat-preserving wall (9), reads the humiture in the dry process equipment heat-preserving wall (9).

Claims

1. device of forming by two bulb (4), the panel (2) that temperature and humidity value scale is arranged, two glass capillaries (1), two strip metal kapillaries (3) and kettle (6), cotton yarn (5) etc.

2. according to the device of claim 1 regulation, it is characterized in that: the scale on the panel (2) is heterogeneous, in bulb (4), be full of colored liquid, bulb (4) and metal capillary (3), glass capillary (1) communicate in inside, and the height of temperature can be shown on panel (2) by the effect glass kapillary (1) that expands with heat and contract with cold of liquid.

3. according to the device of claim 1 regulation, it is characterized in that: humiture display panel (2), glass capillary (1) are hung on outside the dry Processing Room, and bulb (4), kettle (6), cotton yarn (5) etc. are hung in the dry Processing Room.This device can be applicable to tobacco flue-curing processing; Mushroom oven dry processing; Date oven dry processing; Used for drying corps processing; Vegetables oven dry processing; Chinese crude drug oven dry processing booth fruits and vegetables are produced; Planting edible mushroom etc.
