Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof air heaters, in particular to an explosion-proof air heater for use in dusty places. Background Art

[0002] The fan heater is a combined unit consisting of a ventilator, a motor and an air heater. It is suitable for various types of workshops and can be used for circulating air heating when the air does not contain dust and flammable or explosive gases. The fan heater can be used independently for heating, generally to supplement the insufficient part of the radiator or use the radiator as on-duty heating, and the rest of the heat load is borne by the fan heater.

[0003] At present, when traditional heaters are in use, they achieve the functions of heating and blowing through the fan and heating components. In this process, dust will inevitably enter the body of the heater, so that the blown air will carry some dust impurities, affecting the quality of the warm air. In addition, the dust inside the heater is not easy to clean, and when it is used again, it will be scattered with the circulation of air in the body.

[0004] The patent document with patent number: CN 220689382 U includes a box body and a fan, the fan is installed inside the box body; two opposite inclined platforms are opened inside the box body; the inclined platform is located at the bottom of the box body; a groove body is provided at the angle below the inclined platform, and the groove body is designed to be parallel to the side of the box body; a dust collection sponge is installed in the groove body, and the dust collection sponge and the groove body are connected in a removable manner; a rear cover plate is provided at the air inlet of the box body; an installation groove is fixedly installed on the outside of the rear cover plate; a filter is placed inside the installation groove; the utility model is provided with a filter screen, and when the equipment is working, air is taken in through the air inlet of the box body, and dust will enter the box body with the circulation of airflow at this time, and the filter screen provided at the air inlet can effectively prevent dust from entering, thereby ensuring the cleanliness of the exhaust gas.

[0005] Although the above patent number removes dust from the air through the filter and the dust sponge, as the filter and the dust sponge are used for a long time, a large amount of dust will adhere to the filter and the dust sponge, which will change the ventilation effect of the filter and the dust sponge, thereby reducing the air intake and air output of the heater. At this time, the staff will need to disassemble and clean it. If the device is used in a place with heavy sand and dust at a later time, the staff will need to frequently disassemble and clean it, which will increase the labor problem of the staff.

Embodiment 3

[0039] like Figure 1-Figure 6 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0040] The heating assembly 3 includes a U-shaped track 31, and the two ends of the inner cavity wall of the heating box 2 are fixedly connected with the U-shaped track 31 respectively. The inside of the U-shaped track 31 is slidably connected with a long rod 32. A fixing frame 33 is fixedly connected at equal intervals between the two groups of long rods 32, and a heating wire 34 is fixedly connected to one side of the fixing frame 33.

[0041] The long rod 32 , the fixing frame 33 and the heating wire 34 are removed from the heating box 2 through the U-shaped track 3 , so that the heating wire 34 can be disassembled from the fixing frame 33 and replaced at a later time.

[0042] The working principle and use process of this utility model:

[0043] In use:

[0044] When working, first, the driving motor 43 is started. When the driving motor 43 is working, it will drive the fan blades 44 to rotate. When the fan blades 44 rotate, the outside air begins to be sucked into the fan duct 41. When the driving motor 43 is working, the heating wire 34 is also started, and the heating wire 34 begins to heat the air.

[0045] As the air enters, first, the air will flow through the middle of the grid mesh plate 521. At this time, the larger impurities in the air can be filtered out through the grid mesh plate 521. At this time, the air flows between the first dust shield plate 53 and the second dust shield plate 54. At this time, the first dust shield plate 53 and the second dust shield plate 54 cooperate with each other to block smaller impurities and larger dust, and make the larger dust and impurities fall into the dust hopper 551 under the action of gravity. As the air flows through the second dustproof plate 54, at this time, it will flow through the middle of the dust-blocking net 562. At this time, the smaller dust in the air will be filtered out through the dust-blocking net 562. At this time, the filtered air will enter the heating box 2 from the fan duct 41. At this time, the heated air in the heating box 2 is taken away and discharged from the exhaust pipe 7.

[0046] When the blocking mesh plate 521 needs to be cleaned later, first, the dual-axis motor 522 is started. When the dual-axis motor 522 is working, it will drive the lifting threaded rod 524 to rotate. When the lifting threaded rod 524 rotates, it will drive the triangular scraper 525 to move upward or downward. When the triangular scraper 525 moves upward or downward, the blocking mesh plate 521 can be cleaned, and the cleaned impurities and dust are pushed into the dust collecting hopper 551 for unified collection later.

[0047] When the dust screen 562 needs to be cleaned, the driving motor 43 drives the fan blades 44 to rotate, which will also drive the spline sleeve 46 and the spline shaft 563 to rotate. When the spline shaft 563 rotates, it will drive the scraper rod 564 to rotate. When the scraper rod 564 rotates, the dust screen 562 will start to be cleaned. The cleaned dust will flow into the dust collecting hopper 551 through the inclined plate 57 and finally fall into the dust collecting box 553.

[0048] When the ash box 553 needs to be cleaned later, first, the pin in the spring latch 555 is pulled to disengage the pin from the latch seat 554. After disengagement, the ash box 553 is pulled outward to facilitate cleaning of dust in the ash box 553 later.

[0049] By removing the bolts on one side of the inspection plate 6, the inspection plate 6 can be removed. After removal, the long rod, the fixing frame and the heating wire 34 can be taken out from the heating box 3 to facilitate the removal of the heating wire 34 from the fixing frame 33 and the replacement at a later time.
