[0027] As Figures 1 to 4 shown, an embodiment of the present utility model provides a mine heating fan unit, which includes a heating fan housing 1. A heating fan unit is installed inside the heating fan housing 1. Circular air inlet pipes 2 and an air outlet pipe 3 are respectively and fixedly connected to both sides of the heating fan housing 1. The circular air inlet pipes 2 and the air outlet pipe 3 are both communicated with the heating fan housing 1. A dust removal component 4 is provided in the circular air inlet pipe 2. The dust removal component 4 includes a baffle 41. The baffle 41 is fixedly connected to the circular air inlet pipe 2. A plurality of ventilation slots are provided on one side of the baffle 41. Filter meshes 42 are fixedly connected in all the ventilation slots. A driving motor 43 is fixedly connected to one side of the baffle 41. The main shaft of the driving motor 43 is fixedly connected to a fixing plate 44. Mounting plates 45 are fixedly connected to both sides of the fixing plate 44. A cleaning brush 46 is installed on one side of the mounting plate 45. During use, under the action of the heating fan unit, air flow enters the heating fan housing 1 through the circular air inlet pipe 2, and after being heated by the heating fan unit, it is discharged through the air outlet pipe 3. When the air flow enters, it first passes through the filter mesh 42 on the baffle 41 to filter the dust carried in the air flow, so that the dust is blocked on one side of the filter mesh 42. Then the driving motor 43 is turned on, driving the two fixing plates 44 to rotate. When rotating, the cleaning brush 46 cleans the filter mesh 42, sweeping the dust on the surface of the filter mesh 42, cleaning the dust on the surface of the filter mesh 42 in real time, ensuring the permeability of the filter mesh 42 and avoiding blockage.
[0028] Specifically, the length of the cleaning brush 46 is greater than the length of the ventilation slot, and the length of the cleaning brush 46 is less than the radius of the baffle 41. When the cleaning brush 46 rotates, the rotation range can cover the filter mesh 42 on the baffle 41, reducing the cleaning dead angle.
[0029] Specifically, the inner wall cross-section of the circular air inlet pipe 2 is inclined. A through groove is provided at a position on the inner wall of the circular air inlet pipe 2 close to the baffle 41. Fixed blocks 5 are fixedly connected to both sides of the through groove on the outside of the circular air inlet pipe 2. Insertion slots are provided on one side of the two fixed blocks 5 facing each other. One end of the insertion slot penetrates through the fixed block 5, and the insertion slot faces the opening of the circular air inlet pipe 2. A sliding rod 6 is inserted into the insertion slot. A dust collection box 7 is fixedly connected between the two sliding rods 6. An installation groove penetrating through is provided on one side of the dust collection box 7 facing the heater housing 1. A sponge block 8 is fixedly connected to the inner wall of the installation groove. When the heater is working, affected by the air flow, although the dust is cleaned off by the cleaning brush 46, it drifts around in the circular air inlet pipe 2 due to the influence of the air flow. After the air flow enters the circular air inlet pipe 2, an air flow branch will be formed at the through groove. The air flow continuously entrains some dust into the dust collection box 7 for collection. The air flow passes through the sponge block 8, and the dust remains on one side of the sponge block 8. After that, when the heater is turned off, the cleaning brush 46 continues to clean. At this time, there is no air flow, and the cleaned dust slowly falls, passes through the through groove and enters the dust collection box 7 for collection. When there is more dust in the dust collection box 7, the dust collection box 7 can be removed for cleaning. Through the dust collection box 7, the dust in the circular air inlet pipe 2 is collected, avoiding too much dust accumulation in the circular air inlet tube.
[0030] Specifically, a guide plate 9 is fixedly connected to the inner wall of the through groove. A plurality of sponge plates 10 are fixedly connected to the bottom surface inside the dust collection box 7. All the sponge plates 10 are arranged in an array. The guide plate 9 changes the direction of part of the air flow, so that part of the air flow can enter the dust collection box 7 to clean the dust. The plurality of sponge plates 10 can improve the binding effect on the dust and avoid a large amount of dust from returning to the circular air inlet tube.
[0031] Specifically, rotating seats 11 are rotatably connected to both sides of the heater housing 1. A support frame 12 is fixedly connected between the two rotating seats 11. The heater housing 1 is rotatably connected to the support frame 12, which can conveniently adjust the wind direction of the heater.
[0032] Specifically, two fixed rods 13 are fixedly connected to one side of the heater housing 1. An arc-shaped plate 14 is fixedly connected to one end of the fixed rod 13. An arc-shaped through groove is provided on the arc-shaped plate 14. A round rod 15 is slidably connected in the arc-shaped through groove. A threaded groove is provided at one end of the round rod 15, and a nut is threadedly connected in the threaded groove. A support plate 16 is fixedly connected to one side of one of the rotating seats 11. The support plate 16 is fixedly connected to the round rod 15. The support plate 16 is attached to one side of the arc-shaped plate 14. When vertically adjusting the wind direction of the heater housing 1, rotate the heater housing 1. The support plate 16 drives the round rod 15 to slide in the arc-shaped through groove. Then rotate the nut. Through the extrusion of the nut on the support plate 16, the round rod 15 is fixed, so that the heater is fixed in the adjusted wind direction.
[0033] Specifically, metal blocking nets 17 are provided on one side of the circular air inlet pipe 2 and the air outlet pipe 3. The mesh of the metal blocking net 17 is relatively large, which will not affect the passage of air flow, but only block larger garbage and gravel to prevent the gravel from scratching the filter screen 42.
[0034] Working principle: Adjust the wind direction of the heater housing 1 vertically. Rotate the nut, and fix the round rod 15 through the extrusion of the nut and the support plate 16. When in use, under the action of the heater unit, the air flow enters the heater housing 1 through the circular air inlet pipe 2, and after being heated by the heater unit, it is discharged through the air outlet pipe 3. When the air flow enters, it first passes through the filter screen 42 on the baffle plate 41 to filter the dust carried in the air flow, so that the dust is blocked on one side of the filter screen 42. Then, the drive motor 43 is turned on accordingly, driving the two fixing plates 44 to rotate. During rotation, the cleaning brush 46 cleans the filter screen 42, sweeping the dust on the surface of the filter screen 42. The deflector 9 changes the direction of part of the air flow, enabling part of the air flow to enter the dust collection box 7. When the heater is turned off, the cleaning brush 46 continues to clean. At this time, there is no air flow, and the cleaned dust slowly falls, passes through the through groove, and enters the dust collection box 7 for collection. When there is more dust in the dust collection box 7, the dust collection box 7 can be removed for cleaning.
