DETAILED DESCRIPTION

[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0025] Reference Figure 1-3 The cleanable pneumatic conveying equipment includes: a silo 1, a cover plate 9 provided on the silo 1, a motor 10 provided at the lower end of the cover plate 9, a rotating shaft 11 provided at the lower end of the motor 10, first connecting rods 12 provided on both sides of the rotating shaft 11, a first brush 13 provided at one end of the first connecting rod 12, a second connecting rod 14 provided at the lower end of the rotating shaft 11, and a second brush 15 provided at one end of the second connecting rod 14. The design of the motor 10, rotating shaft 11, connecting rods, and brushes enables automatic cleaning of the inner wall of the silo 1, eliminating the need for manual intervention and reducing cleaning costs. When the equipment is in operation, the brush rotates with the rotating shaft 11, automatically removing material adhering to the inner wall of the silo 1, thereby improving work efficiency. The first brush 13 and the second brush 15 respectively clean the cylindrical and conical parts of the silo 1, ensuring that there are no blind spots.

[0026] The silo 1 has a cylindrical top and a conical bottom. The first brush 13 contacts the inner wall of the cylindrical portion of the silo 1, while the second brush 15 contacts the inner wall of the conical portion of the silo 1. The brushes are positioned according to the shape of the silo 1 (cylindrical top, conical bottom) to ensure close contact with the inner wall, improving cleaning efficiency and making cleaning more efficient and thorough.

[0027] At the lower end of silo 1 is an air extraction pipe 2, one end of which is equipped with an air pump 3, and one end of which is equipped with an air guide pipe 4. The lower end of air guide pipe 4 is connected to a vent pipe 5, the lower end of which is equipped with a sealing plug 6, and the lower end of sealing plug 6 is connected to a filter bag 7. The design of air extraction pump 3, air guide pipe 4, vent pipe 5, and filter bag 7 achieves gas recycling, reduces dust leakage, and protects the environment. The provision of filter bag 7 effectively intercepts dust in the material, ensures the cleanliness of the conveying gas, and extends the service life of the equipment.

[0028] A workbench 8 is provided at the lower end of the air pump 3. The workbench 8 provides a stable support for the air pump 3, ensuring the stability of the equipment operation.

[0029] The air guide tube 4 and the vent tube 5 are connected by threads, which makes it easy for users to disassemble and replace them as needed, thereby improving the flexibility of the equipment.

[0030] The bag opening at the upper end of the filter bag 7 is elastic, and the filter bag 7 is sleeved on the sealing plug 6. The filter bag 7 can be tightly sleeved on the sealing plug 6 to prevent gas leakage and improve the filtering effect. The design of the elastic bag opening also makes the replacement of the filter bag 7 more convenient and quick.

[0031] like Figure 3 As shown, the cover plate 9 is provided with protrusions 17 on both sides, each with a second threaded hole 1701. A groove 18 and a first threaded hole 19 are provided at the top of the silo 1. The protrusions 17 and groove 18 match in size, and the first threaded hole 19 extends vertically through the groove 18. Bolts 20 are provided on both sides of the silo 1, extending through the first and second threaded holes 1701 to lock the protrusions 17 with the grooves 18. The design of the protrusions 17, groove 18, first and second threaded holes 19 and 1701, and the bolts 20 ensure a secure connection between the cover plate 9 and the silo 1, preventing material and gas leaks. This connection also facilitates installation, removal, and cleaning of the cover plate 9.
