Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, specifically a dust-free feeding rotary vibrating screen. Background Technology

[0002] The rotary vibrating screen is a high-precision fine powder screening machine with low noise, high efficiency, and quick screen replacement in 3-5 minutes. It has a fully enclosed structure and is suitable for screening and filtering granular, powder, and viscous materials. The rotary vibrating screen uses a vertical motor as the excitation source. Eccentric weights are installed at the upper and lower ends of the motor to convert the rotational motion of the motor into three-dimensional motion of horizontal, vertical and inclined motion, and then transmit this motion to the screen surface. Adjusting the phase angle at the upper and lower ends can change the movement trajectory of the material on the screen surface.

[0003] The applicant discovered through a search that a Chinese patent discloses "A Dust-Free Feeding Vibrating Screen" with publication (announcement) number "CN206810677U". This patent mainly uses a feeding mechanism to transport materials to the vibrating screen, which meets the requirements of the material screening environment and effectively prevents materials from drifting into the air during feeding, thus avoiding pollution of the surrounding working environment and affecting the health of operators. However, this device does not separate impurities mixed in the material during feeding. Therefore, we propose a dust-free feeding vibrating screen. Utility Model Content

[0022] In this embodiment, the vibrating screen adopts the XZS800-2F type vibrating screen. This type of vibrating screen can screen materials with a particle size ≤40mm, and the production rate is 100~1400kg / h. The filter screen 13 has different models. The filter screen 13 can be removed from the through groove by the handle and replaced. The dust collection cylinder 11 is made of transparent acrylic material, which makes it easy to observe the amount of dust in the dust collection cylinder 11. Two sets of connecting pipes 10 and dust collection cylinders 11 are provided. By opening and closing the valves 14 on the surface of the two sets of connecting pipes 10, the two sets of dust collection cylinders 11 can be used alternately.

[0023] A through groove is provided at the connection between the storage bin 6 and the dust collection bin 8, and a filter screen 13 is snapped into the through groove. A handle is installed on the left side of the filter screen 13. Two sets of connecting pipes 10 and dust collection cylinders 11 are provided, and valves 14 are installed on the surface of both sets of connecting pipes 10. The connecting pipes 10 and dust collection cylinders 11 are detachably connected, and scale lines are provided on the surface of the dust collection cylinders 11.

[0024] Specifically, by setting up a dust pump 9 and a filter screen 13, the dust pump 9 will draw the dust mixed with the material in the storage bin 6 into the dust storage bin 8. At the same time, the filter screen 13 can prevent the material from being sucked into the dust storage bin 8. The dust in the dust storage bin 8 will fall from the connecting pipe 10 to the dust collection cylinder 11 below and be collected by the dust collection cylinder 11, so as to prevent the dust mixed with the material from being dispersed into the air and causing pollution to the working environment.

[0025] Example 2, please refer to the appendix. Figure 1 -Attached Figure 4 This utility model provides a technical solution: a dust-free feeding rotary vibrating screen, including a rotary vibrating screen body 1, a feed pipe 2 installed through the top surface of the rotary vibrating screen body 1, a first discharge pipe 3 and a second discharge pipe 4 respectively connected through the left and right sides of the rotary vibrating screen body 1, a support base 5 provided at the rear of the rotary vibrating screen body 1, a storage box 6 installed on the top surface of the support base 5, a feed hopper 7 installed through the top surface of the storage box 6, a dust collection box 8 installed on the back of the storage box 6, a dust suction pump 9 installed on the top surface of the dust collection box 8, a connecting pipe 10 installed through the bottom surface of the dust collection box 8, a dust collection cylinder 11 connected to the bottom end of the connecting pipe 10, and a discharge pipe 12 connected through the front of the storage box 6, with the bottom end of the discharge pipe 12 fixedly connected to the top surface of the feed pipe 2.

[0026] In this embodiment, straight pipes 15 are slidably installed on the surfaces of the first discharge pipe 3 and the second discharge pipe 4, so that the straight pipes 15 can slide to fit against the discharge groove 17 opened on the top surface of the top cover 164. After the material is discharged from the first discharge pipe 3 and the second discharge pipe 4 into the straight pipe 15, it will fall from the straight pipe 15 into the material collection cylinder 163 below. When one set of material collection cylinders 163 is full, the turntable 162 is rotated to move the set of material collection cylinders 163 to the bottom of the circular groove 18, and then the cylinder cover is sealed through the circular groove 18. The other set of material collection cylinders 163 will move to the bottom of the discharge groove 17, so that the two sets of material collection cylinders 163 can be used alternately.

[0027] Straight pipes 15 are slidably installed on the surfaces of the first discharge pipe 3 and the second discharge pipe 4. A rotating assembly 16 is provided directly below the first discharge pipe 3 and the second discharge pipe 4. The rotating assembly 16 includes a base 161, a turntable 162, a material collection cylinder 163 and a top cover 164. The bottom surface of the turntable 162 is rotatably connected to the top of the base 161 via a rotating rod. The top cover 164 is fixedly connected to the top of the base 161 via a connecting rod. The material collection cylinder 163 is snapped onto the top surface of the base 161, and two sets of material collection cylinders 163 are provided. The top surface of the top cover 164 has a discharge groove 17 and a circular groove 18. The straight pipe 15 and the discharge groove 17 are compatible with each other. The diameter of the circular groove 18 is equal to the diameter of the material collection cylinder 163.

[0028] Specifically, by sliding the straight pipe 15 to fit the discharge trough 17 opened on the top surface of the top cover 164, when the material in the screen cylinder is discharged from the first discharge pipe 3 and the second discharge pipe 4, it can enter the material collection cylinder 163 below through the straight pipe 15, thus avoiding the material from scattering to the surroundings and causing resource waste during discharge.

[0029] Working principle:

[0030] The first step is to pour the material from the feed hopper 7 into the storage box 6, turn on the dust pump 9, the dust pump 9 will draw the dust mixed with the material in the storage box 6 into the dust storage box 8, and at the same time the filter screen 13 can prevent the material from being sucked into the dust storage box 8. The dust in the dust storage box 8 will fall from the connecting pipe 10 into the dust collection cylinder 11 below.

[0031] In the second step, the material is conveyed from the storage bin 6 to the screen cylinder of the vibrating screen through the discharge pipe 12. The sliding straight pipe 15 is in contact with the discharge chute 17 opened on the top surface of the top cover 164. The material in the screen cylinder will fall from the first discharge pipe 3 and the second discharge pipe 4 into the straight pipe 15, and then fall from the straight pipe 15 into the material collection cylinder 163 below. When one set of material collection cylinders 163 is full, the turntable 162 is rotated to move the set of material collection cylinders 163 to the bottom of the circular groove 18, and then the cylinder cover is sealed through the circular groove 18. The other set of material collection cylinders 163 will be moved to the bottom of the discharge chute 17, so that the two sets of material collection cylinders 163 can be used alternately. At this point, the entire process is completed.
