The utility model aims to overcome the defects and shortcomings of the prior art, and provides a device for improving the detection quality of a metal detector, which can quickly and timely separate dust, reduce the interference on the detection of the metal detector, improve the detection quality, prevent the dust from attaching to tablets, facilitate the subsequent bottling work, ensure the product quality and reduce the maintenance rate of subsequent equipment.
In order to achieve the purpose, the utility model provides the following technical scheme:
the utility model provides a device for improving metal detector detection quality, is including being the passageway of vertical setting, supplies tablet top-down to pass through from its inside, metal detector is installed to one side on the upper portion of passageway for detect the metal foreign matter in the tablet that passes through from the inside of passageway, its characterized in that: also includes:
the dust removal box is fixedly connected to the lower end of the channel, the upper end and the lower end of the dust removal box are both arranged in an open manner, and a plurality of small holes which are densely distributed are formed in the peripheral side wall of the dust removal box;
and the negative pressure box is sleeved outside the dust removal box, a closed interlayer is formed between the negative pressure box and the dust removal box, and an outlet is arranged on one side of the bottom of the negative pressure box and connected with a draught fan.
Furthermore, an upper port of the channel is butted with an outlet end of the tablet press, and a lower port of the dust removal box is butted with the tablet conveying device.
Furthermore, the dust removal box is of a conical structure with a large upper part and a small lower part.
Further, the diameter of each orifice is smaller than the average diameter of the tablet.
Furthermore, the outlet end of the induced draft fan is connected with a cyclone separator through a pipeline.
Compared with the prior art, the utility model has the beneficial effects that:
according to the utility model, the dust removal device is additionally arranged at the bottom (outlet part) of the existing detection channel, negative pressure is generated by extracting air, dust can be quickly and timely separated, the interference on the detection of the metal detector is reduced, the detection quality is improved, the dust is prevented from being attached to the tablets, the subsequent bottling work is facilitated, the product quality is ensured, and the maintenance rate of subsequent equipment is reduced.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 and 2, a device for improving the detection quality of a metal detector comprises:
the channel 1 is vertically arranged, and the tablet passes through the channel from top to bottom;
a metal detector 2 installed at one side of the upper portion of the passage 1 for detecting a metal foreign substance in the tablet passing through the inside of the passage 1;
the dust removal box 3 is fixedly connected to the lower end of the channel 1, the upper end and the lower end of the dust removal box 3 are both arranged in an open manner, and a plurality of small holes 4 are densely distributed in the peripheral side walls of the dust removal box 3;
and the negative pressure box 5 is sleeved outside the dust removal box 3, a closed interlayer 6 is formed between the negative pressure box 5 and the dust removal box 3, and an outlet is formed in one side of the bottom of the negative pressure box 5 and is connected with an induced draft fan 7.
In the present invention, the upper port of the channel 1 is connected to the outlet end of the tablet press (not shown), and the lower port of the dust removing box 3 is connected to the tablet feeding device (not shown). Thereby, the tablet input and output channel 1 is realized.
In the utility model, the dust removal box 3 is in a conical structure with a large top and a small bottom. Thereby, the air inside is advantageously extracted.
In the present invention, the diameter of each small hole is smaller than the average diameter of the tablet. This can prevent the tablet from being pulled out.
In the present invention, the outlet end of the induced draft fan is connected with a cyclone separator (not shown in the figure) through a pipeline.
The utility model is further described below with reference to the accompanying drawings:
during operation, tablets pressed and formed by the tablet press continuously enter from the upper port of the channel 1, and the metal detector 2 detects metal foreign matters in the passing tablets.
In this in-process, draught fan 7 extracts the air in the dust removal case 3 for the inside production negative pressure of dust removal case 3 and passageway 1, from this the dust is quick, timely through dust removal case 3 a plurality of aperture 4 and the 6 separation of inclosed intermediate layer of inclosed 4 on the lateral wall all around, finally collects cyclone, and waste gas is discharged, and granule and powder are then concentrated the collection and are handled.
Therefore, dust cannot be dispersed in the channel 1, interference on detection of the metal detector 2 is reduced, and detection quality is improved. In addition, the dust can not be attached to the tablets, thereby being beneficial to subsequent bottling work, ensuring the product quality and reducing the maintenance rate of subsequent equipment.
