Description

Technical Field

[0001] The utility model relates to the technical field of cotton textile machinery, in particular to a dust filter rotary suction nozzle pipe joint device. Background Art

[0002] According to common knowledge, the dust filtration equipment currently used in the textile industry is a two-stage filtration equipment configuration: the first stage is a disc filter unit, and the second stage is a cotton dust filter unit. The primary function of the primary dust filtration equipment is to collect, filter, and separate fibrous impurities from the air being processed. That is, after the air containing fibrous dust enters the housing of the primary dust filtration equipment, the fibrous impurities are retained on the disc filter. The rotary suction nozzle uses the suction force of the dust exhaust fan to remove the fibrous impurities, and then enters the fiber separator through the dust exhaust pipe to achieve the separation of fibers from air. However, in actual production, the dust filter nozzle pipe and the dust exhaust pipe are both made of metal materials, and the connection method of their joints is a plug-in structure. When the rotary suction nozzle rotates, fibrous impurities often accumulate and entangle at the pipe interface. In addition, the nozzle pipe and the dust exhaust pipe are not concentric, which causes friction and heat generation in the metal material of the nozzle pipe and the dust exhaust pipe joint. A large amount of entangled fibers will pose a fire safety hazard and affect the normal operation of production. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, the purpose of the invention of this utility model is to provide a dust filter rotating nozzle pipe joint device to solve the problem of accumulation and entanglement of fiber impurities in the rotating nozzle pipe and the dust exhaust pipe joint, avoid friction and heat between the nozzle pipe and the dust exhaust pipe joint, and eliminate fire safety hazards.

[0004] To achieve the above-mentioned purpose of the invention, the utility model includes a nozzle transmission motor, a rotating nozzle, a disc filter, a dust filter box, a fiber separator, and a dust exhaust fan. The dust filter bracket arranged in the dust filter box is equipped with a nozzle transmission motor, and the pulley of the nozzle transmission motor is connected to the nozzle rotating pulley via a belt. One end of the nozzle center axis passing through the disc filter is connected to the nozzle rotating pulley, and the other end is connected to the rotating nozzle. The inlet of the rotating nozzle is in contact with the disc filter, and the outlet of the rotating nozzle is connected to the nozzle pipe. The nozzle pipe is connected to the fiber separator via the dust exhaust pipe, and the fiber separator is connected to the dust exhaust fan. A nozzle pipe joint device is also provided between the nozzle pipe and the dust exhaust pipe.

[0005] Furthermore, the suction nozzle pipe joint device includes a fastening ring, a suction cup rubber ring, and a suction cup. The suction cup rubber ring is fixedly connected to the suction nozzle pipe outlet through the fastening ring, and the suction cup is fixedly connected to the dust exhaust pipe inlet. There is a gap between the suction cup rubber ring and the suction cup, and the gap is 2mm.

[0006] Furthermore, the suction cup rubber ring is made of wear-resistant rubber material, and the suction cup is made of steel plate.

[0007] Furthermore, the suction nozzle pipe and the dust exhaust pipe are concentrically arranged.

[0008] Furthermore, the rotating suction nozzle rotates in a circle along the disc filter with the suction nozzle central axis as the center.

[0009] Compared with the prior art, during the production and operation of the dust filtering equipment, the present invention allows the suction cup rubber ring to be tightly attached to the suction cup due to the airflow adsorption effect of the rear dust exhaust fan, forming a sealed channel at the interface between the suction nozzle pipe and the dust exhaust pipe, thereby ensuring that the dust removed by the rotating suction nozzle passes normally, ensuring that the fibers on the disc filter screen are discharged into the fiber separator, and ensuring that they are collected and compacted smoothly. In particular, the suction nozzle pipe joint device avoids metal friction between the inserted suction nozzle pipe and the dust exhaust pipe and the accumulation and entanglement of dust impurities, eliminating the hidden danger of fire accidents. The non-contact suction nozzle pipe joint device between the suction cup rubber ring and the suction cup avoids wind leakage caused by misalignment between the inserted suction nozzle pipe and the dust exhaust pipe. It has high operating efficiency, simple structure, and safe use, effectively ensuring the stability of production safety quality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] like Figure 1 、 Figure 2As shown, the utility model mainly includes a nozzle transmission motor 1, a rotary nozzle 3, a disc filter 6, a dust filter box 7, a fiber separator 11, and a dust exhaust fan 12. The dust filter bracket 2 arranged in the dust filter box 7 is equipped with a nozzle transmission motor 1, and the pulley of the nozzle transmission motor 1 is connected to the nozzle rotating pulley 4 via a belt. One end of the nozzle center axis 5 passing through the disc filter 6 is connected to the nozzle rotating pulley 4, and the other end is connected to the rotating nozzle 3. The inlet of the rotating nozzle 3 is in contact with the disc filter 6. Under the action of the dust filter exhaust fan, the dusty cotton fibers are adsorbed on the disc filter 6.

[0015] The nozzle drive motor 1 drives the rotating nozzle 3 to perform circular motion along the nozzle central axis 5. The inlet of the rotating nozzle 3 absorbs cotton fibers from the disc filter 6. The outlet of the rotating nozzle 3 is connected to the nozzle pipe 8. The nozzle pipe 8 is connected to the fiber separator 11 through the dust exhaust pipe 10. The fiber separator 11 is connected to the dust exhaust fan 12. The dust exhaust motor 12 is set at the air outlet of the fiber separator 11 and fixed to the dust filter box 7 by a bracket. A nozzle pipe joint device 9 is also provided between the nozzle pipe 8 and the dust exhaust pipe 10.

[0016] Preferably, the suction nozzle pipe joint device 9 includes a fastening ring 13, a suction cup rubber ring 14, and a suction cup 15. The suction cup rubber ring 14 is fixedly connected to the outlet of the suction nozzle pipe 8 through the fastening ring 13, and the suction cup 15 is fixedly connected to the inlet of the dust exhaust pipe 10. There is a gap between the suction cup rubber ring 14 and the suction cup 15, and the gap is 2 mm.

[0017] Preferably, the suction cup rubber ring 14 is made of wear-resistant rubber material, and the suction cup 15 is made of 5mm steel plate material.

[0018] Preferably, the suction nozzle pipe 8 and the dust exhaust pipe 10 are concentrically arranged to ensure good adsorption between the suction cup rubber ring 14 and the suction cup 15.

[0019] During production, the dust filtration equipment operates normally. The nozzle drive motor 1 drives the nozzle rotating pulley 4 to rotate. The nozzle rotating pulley 4 drives the rotary nozzle 3 to rotate via the nozzle central axis 5. The rotary nozzle 3 rotates along the disc filter 6 and, under the suction force of the dust exhaust motor 12, absorbs fibers from the disc filter 6. The fibers are then fed into the fiber separator 11 through the nozzle duct 8 and the dust exhaust duct 10 for collection and compaction. The nozzle duct joint device 9, located between the nozzle duct 8 and the dust exhaust duct 10, has its suction cup rubber ring 14 retracted by the suction force of the dust exhaust motor 12, tightly fitting with the suction cup 15 to form a sealed passage. This ensures that dust removed by the rotary nozzle 3 can smoothly enter the dust exhaust duct 10, eliminating any gaps between the nozzle duct 8 and the dust exhaust duct 10. The suction cup rubber ring 14 made of wear-resistant rubber material and the suction cup 15 made of steel plate material will not generate heat due to friction, and the sealing effect is very good, which effectively eliminates the accumulation and entanglement of dust and impurities between the suction nozzle pipe 8 and the dust exhaust pipe 10, and eliminates fire safety hazards.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
