In order to solve the technical problems, the utility model provides a betel nut whole powder screening device.
The aim of the utility model is achieved by the following technical scheme:
the betel nut whole powder screening device comprises a base, wherein a plurality of elastic structures are fixed at the top of the base along the circumferential direction, the elastic structures are connected with screening boxes, and the screening boxes are connected with vibrating motors; the screening box is provided with a plurality of screens from top to bottom, one end of the screening box matched with the screens is provided with a discharge hole, and a material guide plate is arranged above each screen; the material guide plate gradually inclines downwards from one end of a material outlet corresponding to the screen to the other end of the screen; a blanking port is formed between the lowest end of the material guide plate and the inner wall of the screening box; the top of the screening box is communicated with a discharging hopper.
Further improved, the discharge hole at the bottommost part of the screening box is communicated with a negative pressure pipe, and the negative pressure pipe is communicated with a dust collecting cloth bag through a negative pressure pump.
Further improvement, the hopper cover is hinged and connected to the discharging hopper, and a handle is fixed on the hopper cover.
Further improvement, the discharge ports are positioned in different circumferential directions of the screening box.
Further improvement, install the unloading governing valve on the unloading hopper.
Further improved, the elastic structure is a spring.
Further improvement, the screen mesh gradually inclines downwards to the end corresponding to the discharge hole, and the inclination angle of the screen mesh is not more than 5 degrees.
The utility model has the beneficial effects that:
1. according to the utility model, the guide plate is arranged to enable the betel nut whole powder to be concentrated to one end of the lower screen mesh far away from the discharge port during each screening, so that the betel nut whole powder can be screened fully.
2. The utility model has the advantages of improving screening efficiency and reducing dust pollution by arranging the negative pressure structure.
Drawings
The utility model is further illustrated by the accompanying drawings, the content of which does not constitute any limitation of the utility model.
Fig. 1 is a schematic diagram of the overall structure of the present utility model.
Detailed Description
The utility model will be further described in detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the utility model more apparent.
Example 1
The betel nut whole powder screening device comprises a base 1, an elastic structure 2, a screening box 3, a vibrating motor 4, a discharge hole 5, a guide plate 6, a discharge hole 7, a discharge hopper 8, a negative pressure pipe 9, a negative pressure pump 10, a dust collecting cloth bag 11, a hopper cover 12, a handle 13, a discharge regulating valve 14 and a screen 15.
Wherein, screen cloth 15 sets gradually from top to bottom, and the sieve mesh of screen cloth reduces from top to bottom in proper order. The screening box 3 is provided with a discharge hole 5 matched with the screen 15. In order to ensure that betel nut whole powder can be fully screened, a material guide plate 6 is arranged above the screen 15, and the material under the upper screen is guided to one end of a discharge hole 5 far away from the screen 15 of the next layer by the material guide plate, so that powder can flow out of powder with corresponding specification from the discharge hole after being screened by the screen 15 in the whole process, and the screening effect of the powder is ensured.
During screening, the screen cloth vibrates through the vibrating motor 4, and the vibration effect of the screening box 3 is improved through the elastic structure 2, so that the screening speed is increased.
In order to prevent the screening, the betel nut whole powder is scattered, the negative pressure pipe 9 is communicated with the discharging hole 5 at the bottommost part of the screening box 3, the negative pressure pipe 9 is communicated with the dust collecting cloth bag 11 through the negative pressure pump 10, the screening box 3 is in a negative pressure state through the negative pressure pump 10, and the air flow flows downwards from top to bottom, so that the screening speed is quickened through the air flow, the powder floating and scattering can be effectively reduced, and dust pollution caused by the dust scattering to the air around the device is effectively prevented.
