Abstract

PURPOSE:To safely, surely and effectively heat gas or liquid irrespective of its kinds by installing a block whose end surfaces is connected to a path through a clearance in a box whose inside communicates with the path and forming a lot of medium through holes making the end surfaces communicate with each other in a part except heater arrangement holes of the block. CONSTITUTION:A heater 4 has a hollow cylindrical box 5 the inside of which communicate with a gas path 3, a cylindrical block 6 of aluminum, etc., filled into the central part of the box 5 so as to cut off the gas path 3, and clearance 5a, 5b formed between both end surfaces of the block 6 and both side surfaces of the box 6. Further it has an arrangement holes 9, 10 of a cylindrical heater 7 and a thermostat 8 passing through the block 6 in the radial direction and separated from each other in the axial direction, a lot of gas through holes 11 passing through the block 6 part except the arrangement holes 9, 10, inserting holes 12 for the sheath heater 7 and the thermostat 8 formed in the box 5 part each opposite to one end of the arrangement holes 9, 10, and a cover 13.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a release medium heating device, and more particularly to a release medium heating device which has a high gas heating efficiency and a heater which can be easily replaced.

[0002]

2. Description of the Related Art Conventionally, there is known a device for blowing hot air obtained by heating air by a heater to an object as shown in Japanese Patent Laid-Open No. 2-130855.

Further, Japanese Utility Model Publication No. 55-153155 discloses a spray gun device in which a heating source is attached to the outer circumference of a metal barrel, and a spray gun device in which a heater is provided inside the barrel is also used. No. 63-82454.

[0004]

SUMMARY OF THE INVENTION
In the apparatus as disclosed in Japanese Patent Laid-Open No. 130855, the heater is exposed to the passage of the air to be heated, and the heating of the flammable gas may not be used due to the risk of ignition, and the heater may be disconnected. However, there is a drawback that replacement is troublesome.

[0005] Further, in both the Japanese Utility Model Publication No. 55-153155 and the Japanese Utility Model Publication No. 63-824454, the paint to be sprayed is heated through the barrel to improve its fluidity. However, it is not configured to heat a gas such as air, and therefore its heating efficiency is extremely poor.

[0006]

According to the present invention, there is provided a device for heating a discharge medium, wherein a box inserted into a passage for the discharge medium, the inside of which is communicated with the passage, and an end surface of the box via a gap. Block filled so as to communicate with the above-mentioned passage, a heater arrangement hole formed in this block, and a large number of medium passages communicating between the both end faces formed in the other block portion excluding this heater arrangement hole. It is characterized by comprising a hole.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is an air gun, 2 is a gas discharge nozzle, 3 is a gas passage connecting between the air gun 1 and the gas discharge nozzle 2, and 4 is a heating device inserted in this gas passage 3. 1 to 3, the heating device 4 is provided with a hollow cylindrical box 5 having the inside communicated with the gas passage 3, and the gas passage 3 is cut off at the center of the box 5. A cylindrical block 6 made of aluminum, stainless steel, etc.
The gaps 5a and 5b formed between both end faces of the block 6 and both side faces of the box 5, and the cylindrical heater 7 and the thermostat 8 which penetrate the block 6 in the diameter direction and are axially separated from each other. Arrangement holes 9 and 10, a large number of gas through holes 11 penetrating axially through the block 6 portion excluding the arrangement holes 9 and 10, and the box 5 portion facing one end of each of the arrangement holes 9 and 10, respectively. The sheath heater 7 and the thermostat 8 having the insertion holes 12 formed therein and the lid 13 are formed. In addition, 14 is a lead wire.

Since the discharge medium heating apparatus of the present invention has the above-described structure, the block 6 is heated by the heater 7, and the gas from the passage 3 is formed in the void 5a and the block 6 in a large number in the axial direction. The gas is heated very efficiently by passing through the gas through hole 11. At this time, since the gas does not come into direct contact with the heater 7, there is no fear of ignition even if a flammable gas is used as the gas. It can also be used to heat fluids rather than gases.

Further, the gas pressure is 5 to 10 kg / cm ²
Even if the temperature is increased as described above, this pressure is not applied to the heater 7 and the thermostat 8 so that they are not destroyed and the gas is not contaminated.

Further, the heater 7 and the thermostat 8 can be attached and detached very easily by removing the lid 13.

The thermostat 8 is for detecting the temperature of the block 6 and for properly adjusting the current applied to the heater 7 through the lead wire 14 through a controller (not shown).

Although the air gun is used in the above-described embodiment of the present invention, the box 5 may be directly connected to a hose (not shown) connected to the compressor without using the air gun. .

[0014]

As described above, according to the apparatus for heating a discharge medium of the present invention, it is possible to safely and reliably heat gas or liquid irrespective of the type of the gas, and to replace the heater easily. Has the benefit of.
