Embodiment 1

[0064] Embodiment 1, reference figure 1 , figure 2 , image 3 , a pneumatic heat-generating high-temperature hot air blower, comprising a casing 1, a casing air inlet 2, a casing air outlet 3, an impeller 4, impeller blades 5, an air inlet 6 in the middle of the impeller, an impeller air outlet 7, a blade air outlet 8, and an impeller Inner flow channel 9, impeller disk 10, impeller shaft sleeve 11, casing inner flow channel 12, casing axial side wall 13, casing radial side wall 14, and impeller air outlet 7 is provided with a circle made of fiber fabric. Ring-shaped wind-shielding heat generator 15, the interweaving gap of fiber fabric and filaments on the wind-shielding heat generator constitutes the capillary air outlet 16 of the heat generator, and the ring-shaped wind-shielding heat generator 15 made of fiber fabric is axially both sides and impeller The impeller disk 10 of the air outlet 7 is connected to the blade air outlet 8 (adhesive connection), the radial front ...

Embodiment 2

[0067] Embodiment 2, refer to Figure 4 , Figure 5 , Figure 6 , this example is basically the same as Example 1, the difference is that there is no windshield heat generator outside the air outlet of the impeller in this example, but a circular windshield heater is set in the inner flow channel 12 of the casing outside the radial end of the impeller. Heater 15, the axial edge of the windshield heat generator 15 is connected with the casing axial side wall 13 of the flow channel inside the casing, the radial front end of the capillary air outlet hole 16 of the heat generator communicates with the impeller air outlet 7, and its radial direction The end communicates with the flow channel 12 inside the casing.

[0068] When working, the high-speed airflow processed by the impeller flows through the windshield heat generator in the flow channel inside the casing, and is stagnated and decelerated under the action of the capillary air outlet of the heat generator, most of the mecha...

Embodiment 3

[0070] Embodiment 3, refer to Figure 7 , Figure 8 , Figure 9 , Figure 10 , this example is basically the same as Example 1, the difference is that the windshield heat generator 15 at the air outlet 7 of the impeller of this example is provided with an accelerated centrifugal blade 17 and an accelerated centrifugal flow channel 18 radially outside, and the accelerated centrifugal blade 17 and accelerated centrifugal The radial front end of the flow channel 18 is connected with the air outlet 8 of the impeller blade and the edge of the windshield heat generator 15 , and its radial rear end is connected with the flow channel 12 inside the casing. The second difference is that a windshield heat generator 15 is arranged in the air outlet 3 of the casing in this example, and the peripheral edge of the windshield heat generator 15 is connected with the inner surface of the air outlet 3 of the casing.

[0071] When working, the accelerated centrifugal blade 17 and the accelerat...

Abstract

The invention provides a pneumatic heat generation high-temperature air heater. The pneumatic heat generation high-temperature air heater comprises a case, a case air inlet, a case air outlet, an impeller, impeller blades, an impeller middle air inlet, an impeller air outlet, blade air outlets, an impeller inner side flow channel, an impeller disc, an impeller shaft sleeve, a case inner side flow channel, a case axial side wall and a case radial side wall, and is characterized in that an air stop heat generator is arranged in the case and located at the position, between the impeller air outlet and the case inner side flow channel, of the case radial side wall, and dense heat generator capillary air outlet holes are formed in the air stop heat generator. Based on the pneumatic heat generation principle, air is made to generate heat, and then temperature is raised; the pneumatic heat generation high-temperature air heater has the advantages that the amount of hot air is large, the pressure of the hot air is high, the heat efficiency is high, energy is saved, multiple functions are achieved and the use range is wide, and multiple use requirements of people for high-temperature hot air in production and life can be met.
