Furnace that reduces evaporation consumption

Abstract

The present invention provides a furnace that reduces evaporation consumption comprising: an outer furnance drum for a heating source is provided at a bottom; a set of inner drum in the outer furnance drum, wherein the top of the inner drum is euipped with a sealing ring and a limiting ring below the sealing ring, wherein the limiting ring is pressed against the top edge of the outer furnance drum, an upper cover comprising a disc body and a ring body, wherein the ring body enables the disc body to form an accomodating groove, the disc body is equipped with a communicating pipe communicating with the disc body, wherein the upper part of the ring part is equipped with an overflow pipe in a connecting manner and the upper cover is equipped with a water inlet pipe communicating with the disc body, and a cooling pipe winding the base surface of the disc body, wherein one end of the cooling pipe is connected below the communicating pipe and the other end is conencted with the water inlet pipe. The furnance also comprises a fluid switch valve communicating with the loer part of the inner furnace drum. Therefore, there is no need to replenish water regularly and save energy in refining and boiling extraction.

Description

technical field [0001] The invention relates to a stove for cooking animal bones to extract colloids, especially refers to that the steam generated in the stove can be cooled and condensed into water droplets, and then flow back to the user in the stove. Background technique [0002] Nowadays, it is common to use stoves for cooking animal bones to extract colloids. Their structures are as follows: figure 1 As shown, the stove 10 includes: an outer furnace cylinder 11, the upper part of which has several exhaust holes 12, the lower part of which has several air inlet holes 13, and the inner bottom of the outer furnace cylinder 11 is provided with a heating source 14, the heating source 14 Usually a gas stove; a set of inner furnace cylinder 15 inside the outer furnace cylinder 11, and the outer circumference of the inner furnace cylinder 15 has a distance from the inner circumference of the outer furnace cylinder 11; an upper cover 17, which has several covers Hole 18, the u...

AI Technical Summary

Problems solved by technology

When in use, the inner furnace cylinder 15 is placed with the extract of animal bones and water to be boiled, and the inner furnace cylinder 15 is covered with the upper cover 17, and then heated by the heating source 14. During heating, the heating source 14 The hot air flow is discharged to the exhaust hole 12 through the distance between the inner furnace cylinder 15 and the outer furnace cylinder 11, and at the same time, the air inlet hole 13 is supplied with air to supplement the combustion air; in order to speed up its boiling, the initial heating will control the The heating source 14 is heated at a relatively high temperature. After the extract to be boiled in the inner furnace tube 15 reaches boiling, in order to avoid burning, the heating source 14 is controlled to be heated at a low temperature, and it is enough to keep boiling , the boiling extract to be cooked produces a large amount of steam, and the steam is discharged through the cover hole 18, and the process of cooking and extracting usually takes several days. For example, taking 6 days as an example, the boiling extract to be cooked is discharged from the The cover hole 18 discharges steam, and the steam is discharged quickly, so that the water in the extract to be cooked can escape quickly. In order to avoid scorching caused by insufficient water, it is necessary to open the upper cover 17 regularly during the cooking and extraction to replenish water. Calculated by replenishing 20 liters per hour, 6 days of cooking and extraction must replenish water up to 48 times, and the amount of replenished water is as much as 960 liters. After adding water each time, the heating source 14 needs to be controlled to be heated and boiled. After boiling the extract to boil again, control the heating source 14 to keep boiling at a low temperature. During this period, adding water and controlling the temperature for many times is very labor-intensive, and after adding water, control the heating source 14 to heat quickly The operation of making it boil is an invisible waste of energy, which is actually a big problem, and the rapid evaporation of water in the extract to be boiled will cause the part of the bone glue dissolved in water to be lost with the steam. Therefore, the above-mentioned cooking The extraction stove 10 has poor efficiency and consumes manpower and energy, so there is a need for improvement
