Description

Dust collection device for feed inlet of mixer

Technical Field

The utility model relates to the technical field of dust collection, in particular to a dust collection device for a feed inlet of a mixer.

Background

Blendors are a common type of equipment used for mixing materials, which is commonly used for mixing various particulate and powdery materials. When the light powdery material is mixed by the powder material, the powdery material falls into the mixer and the mixer to be stirred to generate dust, so that the dust drifts away through a feed inlet or other openings: (1) This may reduce a certain component, resulting in poor product quality; (2) The powder material is scattered in the air, so that the air is polluted, the human body is injured, and the loss of ventilation and dust removal equipment is large.

In order to solve such problems, a separate dust removing device is usually selected to remove the scattered dust, but the dust removed by the dust removing device is difficult to recycle (which mixes the impurities in the air), and the device is expensive, and requires additional energy and space.

Therefore, the device which can effectively collect dust at the feed inlet of the mixer and fully utilize the dust can be designed, and the production cost can be effectively reduced.

Detailed Description

Examples

As further described below with reference to the specific embodiments, as shown in fig. 1 to 5, the dust collecting device for a feed inlet of a mixer of the present embodiment includes a feed cylinder 10, a cylindrical collecting cloth 21 disposed inside the feed cylinder 10, a negative pressure pipe 13 connected to the feed cylinder 10, and a negative pressure machine connected to the negative pressure pipe 13; the feeding barrel 10 is detachably inserted into a feeding port of the mixer 30; the upper and lower ends of the collecting cloth 21 are fixedly connected with the inner wall of the feeding cylinder 10. Specifically, when the mixer 30 needs to feed, the feeding cylinder 10 is inserted into the feeding hole of the mixer 30, then the pipeline for conveying materials is inserted into the feeding cylinder 10 and discharged to the materials, at the moment, the negative pressure machine opens the negative pressure machine to apply negative pressure to the feeding cylinder 10 through the negative pressure pipe 13, so that powder scattered in the mixing cylinder is sucked onto the collecting cloth 21 by the negative pressure to avoid the powder from scattering from the feeding cylinder 10 to the outside, after feeding is completed, the negative pressure machine can be closed, so that the powder attached to the collecting cloth 21 enters the mixer 30 under the action of gravity, and therefore, all the materials can be effectively shaken and discharged into the mixer 30, the proportion of the materials is more accurate, and the powder is prevented from scattering in the air.

A plurality of springs 22 are arranged between the feeding cylinder 10 and the collecting cloth 21 in the embodiment, and the springs 22 are connected with the collecting cloth 21 through a plurality of connecting ropes 24; the length direction of the spring 22 is parallel to the axial direction of the feed cylinder 10; the plurality of springs 22 are distributed along the circumferential direction of the feed cylinder 10. The connecting rope 24 is made of elastic materials. The upper end of the spring 22 passes through the collecting cloth 21 and extends upwards; the upper ends of the plurality of springs 22 are each connected to a stationary ring 23. Specifically, the spring 22 has the function of blocking the collecting cloth 21 from the feeding cylinder 10 so as to have a gap therebetween, so that negative pressure can be generated better. But when the powder on the collecting cloth 21 is required to be shaken into the mixer 30, the fixing ring 23 can be directly shaken, all springs 22 can be driven to shake through the fixing ring 23, and then the collecting cloth 21 is driven to shake through the connecting rope 24. Thus, the operation is more convenient, and the effect is better.

In this embodiment, the feeding device further comprises a cover plate 12 arranged at the upper end of the feeding barrel 10, and the cover plate 12 is hinged with the feeding barrel 10. Specifically, the cover plate 12 is covered first, and then the powder on the collecting cloth 21 is shaken off, so that the powder can be prevented from drifting up again.

The diameter of the inlet barrel 10 in this embodiment is smaller at one end remote from the mixer 30 than at the opposite end. In particular, this slightly frustoconical feed cylinder 10 allows the powder on the collection cloth 21 to fall better into the mixer 30.

The side wall of one end of the feeding barrel 10, which is close to the mixer 30, is provided with an annular clamping plate 11. Specifically, the feeding barrel 10 can be well clamped at the feeding hole of the mixer 30 through the clamping plate 11.

To sum up, in the dust collection device for a feed inlet of a mixer according to this embodiment, when the mixer 30 needs to be fed, the feed cylinder 10 is inserted into the feed inlet of the mixer 30, then the pipe for conveying materials is inserted into the feed cylinder 10 and discharged to the materials, at this time, the negative pressure machine is started to apply negative pressure to the feed cylinder 10 through the negative pressure pipe 13, so that powder material floating in the mixer cylinder is sucked onto the collection cloth 21 by the negative pressure to avoid the powder material from floating in the mixer cylinder 10 to the outside, after the feeding is completed, the negative pressure machine can be closed, so that the powder material attached to the collection cloth 21 enters the mixer 30 under the action of gravity, and thus, all the materials can be effectively shaken and discharged into the mixer 30, so that the proportion of the materials is more accurate, and the powder material can be prevented from floating in the air.

The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
