[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The outer side of the air inlet pipe 41 is provided with a first motor 44. The first motor 44 is connected to a bevel gear assembly 45 for driving the filter plate 42 near the inner end of the air inlet pipe 41. The front and rear sides of the cylinder 3 are both provided with a second motor 46. The inner side of the air inlet pipe 41 is provided with a jet strip 47 near the end of the filter plate 42. The inner ends of the cylinder 3 are rotatably connected with an inner cylinder 48 driven by the second motor 46. The inner cylinder 48 is provided with a ventilation groove 49 at the end corresponding to the air inlet pipe 41.

[0025] The heating cylinder 5 is installed at the exhaust end of the exhaust fan 2 to control the temperature; the dredging piece 6 is installed on the base 1 to dredge the filter plate 42; a ventilation pipe is installed on the side of the heating cylinder 5 away from the exhaust fan 2, the output end of the first motor 44 is coaxially fixedly connected with the driving bevel gear in the bevel gear assembly 45, and the driving bevel gear and the driven bevel gear in the bevel gear assembly 45 are both made of stainless steel; the driven bevel gear in the bevel gear assembly 45 is coaxially fixedly connected with the filter plate 42, the outer wall of the inner cylinder 48 is in contact with the inner wall of the cylinder body 3, and the second motor 46 is coaxially fixedly connected with the inner cylinder 48; a heating strip is provided on the inner side of the heating cylinder 5, and the first motor 44 and the second motor 46 are both servo motors;

[0026] A gas flow sensor is installed at the exhaust end of the exhaust fan 2 near the heating cylinder 5 side, and a temperature sensor is installed at the ventilation pipe end of the heating cylinder 5. The gas flow sensor, the temperature sensor, and the heating strip are all electrically connected to the external controller. The temperature of the supply air is controlled by controlling the heat generated by the heating strip. The gas flow sensor, the temperature sensor, and the heating strip are all existing technologies, so their specific working principles are not described in detail. The two groups of air intake pipes 41, the filter plate 42, the scraper 43, the first motor 44, the bevel gear assembly 45, the second motor 46, the inner cylinder 48, and the ventilation groove 49 cooperate with each other to realize the filtering and air volume adjustment operations at the air intake end, and the alternating replacement of the two groups of air intake pipes 41 can prevent the air supply operation from being affected by cleaning the filter plate 42, thereby improving the air supply efficiency of the device.

[0027] like Figure 1-2 The second embodiment shown is mainly different from the first embodiment in that:

[0028] The dredging member 6 includes an air compressor 61 installed on the base 1, and a solenoid valve 62 is installed at the air extraction end of the air compressor 61, and the solenoid valve 62 is fixedly connected to a suction pipe 63 fixedly connected to the middle part of the upper end of the cylinder 3, and a three-way valve 64 is installed at the exhaust end of the air compressor 61, and the upper and lower sides of the three-way valve 64 are respectively fixedly connected to a conduit 65 for supplying air to the jet strip 47;

The inner end of the jet strip 47 is in the air and is respectively connected with the conduit 65 and the jet holes. When the mesh belt kiln does not need to make up air, the three-way valve 64 is adjusted to make the exhaust end of the air compressor 61 connected with the closed air inlet pipe 41 through the conduit 65 and the jet strip 47, the exhaust fan 2 is turned off and the solenoid valve 62 and the air compressor 61 are turned on. The air compressor 61 extracts and compresses air through the solenoid valve 62, the exhaust pipe 63, the cylinder 3, the inner cylinder 48, the ventilation groove 49, the unclosed air inlet pipe 41, and the filter plate 42, and then the compressed air is blown and cleared through the three-way valve 64, the conduit 65, and the jet strip 47 to the filter plate 42 in the closed air inlet pipe 41.

[0030] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0031] When in use, the user fixes the entire device at the air supply end of the mesh belt kiln, makes the air supply pipe on the right side of the heating cylinder 5 fixedly connected to the ventilation pipe of the mesh belt kiln, and makes the exhaust fan 2, the heating strip in the heating cylinder 5, the two sets of first motors 44, and the second motor 46 electrically connected to the external controller. When it is necessary to replenish air for the inner end of the mesh belt kiln, the exhaust fan 2 is started, and the exhaust fan 2 draws outside air through the cylinder 3, the air inlet pipe 41, and the filter plate 42, wherein the filter plate 42 filters impurities in the air, and then the air is introduced into the kiln through the heating cylinder 5 and the ventilation pipe. When it is necessary to increase the air temperature, the heating strip in the heating cylinder 5 is powered, and the heating strip generates heat and heats the gas passing through through heat exchange;

[0032] When it is necessary to control the air flow rate, the second motor 46 drives the inner cylinder 48 to rotate, so that the ventilation groove 49 in the inner cylinder 48 is offset relative to the air inlet pipe 41, so as to adjust the air inlet diameter and control the wind flow rate. When it is necessary to clean the filter plate 42 at that location, the inner cylinder 48 at that location is adjusted to make the ventilation groove 49 and the air inlet pipe 41 completely offset, and the air inlet pipe 41 at that location is isolated from the cylinder body 3. In this process, the angle of the inner cylinder 48 and the ventilation groove 49 at another location is adjusted to take over the filtering and ventilation operation when the air inlet pipe 41 at that location is closed, so as to reduce the interruption of the air replenishment process of the device due to cleaning. When the air inlet pipe 41 at that location is completely isolated from the cylinder body 3, the first motor 44 is turned on. The first motor 44 drives the filter plate 42 to rotate through the bevel gear assembly 45, and the scraper 43 scrapes and cleans the outer surface of the filter plate 42.
