Description

A uniform feeding device

Technical Field

The utility model relates to the technical field of uniform feeding, in particular to a uniform feeding device.

Background technique

In industrial production, many equipments need materials to enter the equipment evenly, and the vibrating feeder can feed block and granular materials from the storage bin to the receiving device evenly, regularly and continuously. In the sand and gravel production line, it can feed the crushing machinery continuously and evenly, and perform rough screening of the materials. Therefore, it is widely used in the crushing and screening combined equipment in the metallurgy, coal mining, mineral processing, building materials, chemical industry, abrasive and other industries. The vibrating feeder uses the rotation of the eccentric block in the vibrator to generate centrifugal force, so that the movable parts such as the screen box and the vibrator make forced continuous circular or approximate circular motion. The material is continuously thrown on the inclined screen surface with the screen box, and the material is continuously and evenly delivered to the receiving port. Since the vibrating feeder realizes the uniform feeding function through vibration, a large amount of dust will inevitably be generated during its operation, resulting in a serious excess of dust concentration in the air, which will not only pollute the environment, but also affect the physical and mental health of the staff.

Chinese patent document CN214568462U discloses a vibrating feeder, including a bottom plate, a support frame is vertically arranged at both the left and right ends of the bottom plate, a shock absorbing mechanism is vertically arranged at both the front and rear ends of the support frame, a first baffle is arranged at the left part of the upper end of the hopper, a second baffle is hinged at the right end of the first baffle, a butterfly valve is arranged on the discharge pipe, a ventilation window is arranged on the second baffle, a dust removal box is arranged at the upper end of the second baffle, a dust removal pipe is arranged on the second baffle, an exhaust fan is arranged on the dust removal pipe, and an exhaust pipe connected to the dust removal box is arranged on the exhaust fan, and the first baffle and the second baffle are used to prevent the dust of the vibrating feeder from floating. This structure can avoid dust when the vibrating machine is working, but it cannot guarantee that the dust is completely removed. And the vibrating machine is not an independent device, and its next level is generally connected to the conveying equipment or directly connected to the functional equipment (such as a crusher). The material falls from the discharge port of the vibrating machine to the next level equipment by gravity, and dust will appear during the gravity falling process. Therefore, the utility model proposes a uniform feeding device with other dust prevention structures.

The top of the first support column 1 and the second support column 2 are both provided with a support spring 3, and the upper end of the support spring 3 is fixedly connected to the outer shell of the vibration frame 5 through the connecting plate 4. A support plate 8 is provided below the vibration frame 5, and the support plate 8 is used to connect the vibrator 7. A feed port is provided at one end of the vibration frame 5 and a discharge end is provided at the other end. The feed port is higher than the discharge end. A vibration plate 6 is provided in the vibration frame 5 to support the material entering the vibration frame 5, and the vibration plate 6 is tilted. In this embodiment, the vibration plate 6 can be a screen structure or a whole plate structure. In the prior art, a screen is generally used for those with pre-sequence screening requirements, and a whole plate is generally used for those without pre-sequence screening requirements. The vibration frame 5 has openings at its discharge end and feed end, and the rest is a fully enclosed structure.

The dust removal mechanism includes a dust suction device and a water outlet device. The dust suction device includes a dust hood 10, a dust suction pipe 11, an air pump 12 and a dust collector 13. A plurality of dust hoods 10 are arranged on the top of the vibration frame 5. A plurality of dust suction holes are arranged on the top of the vibration frame 5. The dust hoods 10 are matched and connected with the dust suction holes one by one, so that the dust hood 10 is connected with the inside of the vibration frame 5. A screen with a larger mesh number is arranged at the dust suction port, which allows dust to pass through and prevents the material from being sucked into the dust hood 10. The end of the dust hood 10 away from the vibration frame 5 is connected with one end of the dust suction pipe 11. The air pump 12 is arranged on the dust suction pipe 11, and the other end of the dust suction pipe 11 is connected with the dust collector 13.

The water outlet device includes a water outlet plate 14 and a telescopic rod 15. One end of the water outlet plate 14 is hinged to the upper part of the discharge end of the vibration frame 5 through a hinge. One end of the telescopic rod 15 is hinged to the discharge end of the vibration frame 5, and the other end is hinged to the middle part of the lower side of the water outlet plate 14. This structure allows the water outlet plate 14 to rotate freely around the hinge. When the device is working, the angle of the water outlet plate 14 can be changed according to the feeding port of the receiving equipment, which can solve the dust problem at the discharge end of the device.

The water outlet mechanism further includes a water outlet ring 9, which is arranged at the feed end of the vibration frame 5. The water outlet ring 9 can prevent the dust in the vibration frame 5 from entering the air through the feed end.

A flow regulating valve is provided between the connecting pipelines of the water inlet and the water source.

The working principle and use process of this embodiment are as follows:

When in use, the material enters the present embodiment from the feed end, and the vibrator 7 is started. The vibrator 7 drives the vibration plate 6 to make a forced continuous circular or approximately circular motion through its own vibration, and vibrates together, so that the material makes a continuous throwing motion on the inclined vibration plate 6, and evenly enters the receiving device from the discharge end. When the equipment is working, since the discharge end and the feed end are not closed, in order to prevent dust from overflowing from the feed end, a water outlet ring 9 is provided for dust reduction. When discharging, in order to prevent dust generated during gravity discharging and dust from overflowing from the discharge end when the equipment is working, a water outlet plate 14 is provided for dust reduction.

In this embodiment, dust reduction is carried out by atomization, which increases the air humidity, reduces the water consumption, and avoids excessive water content in the material to produce mud.

According to the above embodiments, the present invention can be well implemented. It is worth noting that, based on the above structural design, in order to solve the same technical problem, even if some insubstantial changes or modifications are made to the present invention, the essence of the technical solution adopted is still the same as that of the present invention, so it should also be within the protection scope of the present invention.
