Novel transverse ventilating duct

Abstract

The utility model relates to the technical field of ventilation ducts, in particular to a novel transverse ventilation duct, and in the working process of the novel transverse ventilation duct, air containing metal scraps and dust is sucked in from openings in the two ends of a ventilation duct body. As the air outlet pipe is located at the central axis of the upper end face of the ventilation pipe body, airflow flows in the ventilation pipe body. When the two air flows converge at the collecting hole, turbulent flow is generated due to the opposite directions of the air flows. Due to the turbulent flow phenomenon, flowing of air flow becomes disordered, collision and friction between metal particles and between the metal particles and the air flow are increased, and therefore the trend that the metal particles rise along with the air flow is weakened. And meanwhile, the turbulent flow also changes the buoyancy and drag action of the airflow on the metal particles, so that the metal particles can settle more quickly under the action of gravity and fall into a settling box below through a collecting hole, and the effective separation of the metal particles and the air is realized. The ventilating duct can be widely applied to the technical field of ventilating ducts.

Description

TECHNICAL FIELD

[0001] The utility model relates to a ventilation channel technical field, concretely relates to a novel transverse ventilation channel. BACKGROUND

[0002] In the process of metal processing, such as cutting, grinding, drilling, welding and other processing steps, a large amount of metal debris and dust will float into the air; for example, in the process of metal cutting, the high-speed rotating cutter interacts with the metal material, which will produce a large amount of fine metal particles; and in the grinding process, the friction between the grinding wheel and the metal surface will also make the metal debris fly to the surrounding environment.

[0003] In the traditional ventilation system, the air containing metal particles is directly discharged through the ventilation pipe, and this direct discharge method not only fails to effectively collect and process the metal waste, but also may cause the air quality in the production workshop to decrease, affecting the health of the operators. At the same time, the unrecovered metal waste also increases the production cost of the enterprise. SUMMARY

[0004] In view of the problem that the prior art produces a large amount of metal debris into the air in the process of metal processing, and the air containing metal debris is directly discharged through the ventilation pipe, resulting in a decrease in the air quality in the production workshop and an increase in the production cost of the enterprise; the utility model provides a novel transverse ventilation channel.

[0005] In order to solve the above technical problems, the utility model solves the problems through the following technical schemes:

[0006] A novel transverse ventilation channel, which comprises a ventilation pipe main body and an air outlet pipe connected with the inner cavity of the ventilation pipe main body, the ventilation pipe main body is open at both ends, the air outlet pipe is arranged at the central axis of the upper end surface of the ventilation pipe main body, the lower end surface of the ventilation pipe is provided with a collection hole located below the air outlet pipe, and the lower end surface of the ventilation pipe is fixed with a sedimentation tank located below the collection hole, and the upper end of the sedimentation tank is open.

[0007] In the working process, the air containing metal debris and dust is sucked from the two end openings of the ventilation pipe main body. Since the air outlet pipe is located at the central axis of the upper end surface of the ventilation pipe main body, the airflow flows in the ventilation pipe main body. When the two airflows converge at the collection hole, the turbulence is generated due to the opposite directions of the airflows. The turbulence phenomenon makes the airflow flow become turbulent, increases the collision and friction between the metal particles and the airflow, and thus weakens the tendency of the metal particles rising with the airflow. At the same time, the turbulence also changes the buoyancy and drag force of the airflow on the metal particles, which helps the metal particles to settle more quickly under the action of gravity and fall into the sedimentation tank below through the collection hole, so as to realize the effective separation of the metal particles and the air.

[0008] Preferably, an air extractor is arranged at each of the two ends of the ventilation pipe body, and the air extractor is used to suck external air into the ventilation pipe body.

[0009] The air extractor can ensure that the flow rates of the two air flows are the same, so that the turbulence effect at the collection hole is stable, and the efficiency and stability of the metal particle sedimentation are improved. In addition, the air extractor can absorb dust-containing air from different directions and ensure that the metal particles in the working environment can enter the ventilation pipe body.

[0010] Preferably, a vertical mounting shaft is fixed at the axial position of the collection hole, a mounting ring rotatable along the mounting shaft is sleeved on the mounting shaft, blades are fixed on the outer sidewall of the mounting ring, and the blades are arranged in a circumferential array on the outer sidewall of the mounting ring.

[0011] When the ventilation duct is in operation, the air flow acts on the blades fixed on the outer sidewall of the mounting ring. Since the mounting ring is sleeved on the vertical mounting shaft and can rotate freely, the air flow pushes the blades to rotate the mounting ring around the mounting shaft. The three blades are arranged in a circumferential array on the outer sidewall of the mounting ring and have poor stability under the action of the air flow on both sides, and are easy to rotate. Therefore, the turbulence effect on the air flow can be effectively enhanced, so that the metal particles can be more effectively promoted to sediment under the action of gravity.

[0012] Preferably, support rods are fixed at the upper and lower ends of the mounting shaft respectively, and the two ends of the support rods are fixed on the inner wall of the ventilation pipe body.

[0013] When the ventilation duct is in operation, the air flow pushes the blades to rotate the mounting ring, and at this time, the mounting shaft bears a large torsion and pressure. The support rods fixed at the upper and lower ends of the mounting shaft respectively have their two ends fixed firmly on the inner wall of the ventilation pipe body, thereby providing stable support for the mounting shaft. This makes the mounting shaft stable under various forces generated by the rotation of the blades, and the mounting shaft does not bend, tilt or displace.

[0014] Preferably, a filter plate is arranged at the outlet of the air outlet pipe, and a bolt is further arranged, and the filter plate is fixed on the end face of the outlet of the air outlet pipe through the bolt.

[0015] During the operation of the ventilation duct, the metal particles carried by the air flow entering the sedimentation tank are preliminarily settled under the action of gravity. The filter plate arranged in the sedimentation tank further filters the air flow and intercepts fine metal particles that have not completely settled. The filter plate is fixed on the outer wall of the ventilation pipe body through the bolt, so that the position of the filter plate is stable when the air flow passes through, and the filter plate does not displace or loosen.

[0016] Preferably, a magnetic plate is fixed on the bottom wall of the sedimentation tank.

[0017] During the operation of the ventilation duct, the metal particles are settled into the settling tank. The magnetic plate fixed on the bottom wall of the settling tank generates a magnetic field, which has an adsorption effect on the metal particles, so that the metal particles are more firmly gathered at the bottom of the settling tank. The adsorption force of the magnetic plate helps to more thoroughly collect the metal particles and reduce the residual and re-suspension of the metal particles. The settled metal particles are ensured to be stable in the settling tank, reducing the possibility of secondary pollution caused by the re-mixing of the metal particles into the airflow.

[0018] As a preferred, the side wall of the settling tank is provided with a tank door.

[0019] During the use of the ventilation duct, the settling tank collects a large amount of metal particles. The tank door provided on the side wall of the settling tank provides a convenient channel for cleaning and recycling the settled metal particles. BRIEF DESCRIPTION OF DRAWINGS

[0026] EMBODIMENT

[0027] As Figs. 1-3As shown, the transverse ventilation passage in the embodiment mainly consists of a ventilation pipe body 110, an air outlet pipe 120, a settling tank 130 and the like. The ventilation pipe body 110 is open at both ends, the air outlet pipe 120 is arranged at the central axis of the upper end surface of the ventilation pipe body 110, a collecting hole 1101 is arranged below the air outlet pipe 120 at the lower end surface of the ventilation pipe body 110, the settling tank 130 is fixed below the collecting hole 1101, and the settling tank 130 is open at the upper end. A suction fan 140 is arranged at each opening at both ends of the ventilation pipe body 110, a vertical mounting shaft 1501 is arranged at the central axis of the collecting hole 1101, a mounting ring 1502 is sleeved on the mounting shaft 1501, and three blades 1503 are arranged in a circumferential array on the outer side wall of the mounting ring 1502. A support rod 1504 is fixed at each end of the mounting shaft 1501, and the support rod 1504 is fixed to the inner wall of the ventilation pipe body 110 by welding or the like. A filter plate 1601 is fixed to the outlet of the air outlet pipe 120 by bolts 1602, a magnetic plate 1301 is fixed to the bottom wall of the settling tank 130, and a tank door 1302 is arranged on the side wall of the settling tank 130.

[0028] The working principle of the transverse ventilation passage in the embodiment is as follows:

[0029] The suction fan 140 is started, and air containing metal scraps and dust is sucked from the openings at both ends of the ventilation pipe body 110. The air flows in the ventilation pipe body 110, and due to the position of the air outlet pipe 120, two air flows converge at the collecting hole 1101 to generate turbulence. The turbulence makes the air flow turbulent, weakens the tendency of the metal particles to rise with the air flow, and promotes the metal particles to settle under the action of gravity and fall into the settling tank 130 through the collecting hole 1101. The blades 1503 at the collecting hole 1101 rotate under the action of the air flow, further enhancing the turbulence effect. When the air flow passes through the air outlet pipe 120, the filter plate 1601 at the outlet intercepts the residual fine metal particles. The magnetic plate 1301 at the bottom wall of the settling tank 130 adsorbs the settled metal particles, and the tank door 1302 at the side wall of the settling tank 130 facilitates the cleaning of the collected metal particles and the installation of the internal components of the ventilation pipe body 110.

[0030] Through the above design, the metal particles can be effectively separated from the air, and the separation efficiency is improved. The content of metal particles in the air is reduced, and the air quality of the working environment is significantly improved. The settings of the tank door 1302 and the bolt 1602 fixing mode of the filter plate 1601 facilitate the maintenance and maintenance of the equipment. The settling tank 130 can effectively collect metal particles, facilitating subsequent recycling and reducing enterprise costs.

[0031] In summary, the above is only a preferred embodiment of the present application, and any changes and modifications made within the scope of the patent application of the present application shall be within the scope of the present application.
