Device for removing heavy impurities in reconstituted tobacco slurry

Abstract

A device for removing heavy impurities in reconstituted tobacco slurry comprises a bracket and an impurity-removing container arranged on the bracket, wherein the impurity-removing container is provided with an opened top and is internally provided with a separation plate for separating the inside of the impurity-removing container into a left sedimentation cavity and a right sedimentation cavity; the separation plate is arranged in the vertical direction; the upper part of the left side of the impurity-removing container is connected with a slurry feeding pipe connector which is communicated with the left sedimentation chamber; the upper part of the right side of the impurity-removing container is connected with a slurry discharging pipe connector which is communicated with the right sedimentation chamber; a slurry feeding valve is arranged on the slurry feeding pipe connector; a slurry discharging valve is arranged on the slurry discharging pipe connector; the upper edge of the separation plate is lower than the top edge of the impurity-removing container; and the tops of the slurry feeding pipe connector and the slurry discharging pipe connector are both lower than the upper edge of the separation plate. The device has the advantages of being simple in structure, convenient to operate, low in investment, quick to implement and good in impurity removal effect, and can effectively improve the purity of slurry through production verification, prolong the service life of grinding discs and protect a mill.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing and production, and in particular relates to a device for removing heavy impurities in reconstituted tobacco leaf slurry. Background technique [0002] The raw materials of reconstituted tobacco leaves are complicated. When raw materials such as tobacco stems and tobacco powder are processed and collected in cigarette factories, hard impurities may be mixed in. The reconstituted tobacco leaf slurry may also be mixed with a small amount of hard impurities during the transportation process, which cannot be screened out manually during the production process. , The addition of impurity removal equipment is generally limited by investment, installation space, and implementation period. When the impurities enter the mill with the slurry, they will cause damage to the grinding disc, affect the service life of the grinding disc, and even damage the mill, resulting in increased maintenance and ...

Problems solved by technology

[0002] The raw materials of reconstituted tobacco leaves are complicated. When raw materials such as tobacco stems and tobacco powder are processed and collected in cigarette factories, hard impurities may be mixed in. The reconstituted tobacco leaf slurry may also be mixed with a small amount of hard impurities during the transportation process, which cannot be screened out manually during the production process. , the addition of impurity removal equipment is generally limited by investment, installation space, and implementation period

When the impurities enter the mill with the slurry, they will cause damage to the grinding disc, affect the service life of the grinding disc, and even damage the mill, resulting in increased maintenance and renewal investment, affecting the continuity of production, and the metal debris produced at the same time will affect the product. negative impact on quality

[0003] In the patent No. ZL201520297212.0, the applicant filters out the impurities in the pulp through the filter connected to the feed pipe, and then removes the remaining impurities in the pulp through the metal mesh cylinder during the stirring process. This method uses a filter device to remove impurities in the pulp. It is necessary to install a multi-layer filter in the filter to ensure the effect of removing impurities. In actual use, the cost is relatively high, and when there are small impurities, the filter may be blocked. , not conducive to continuous production

In the patent No. ZL201520323994.0, the applicant recovers the metal fragments in the slurry during the process of transporting the slurry through the impurity removal part. This method can only remove metal impurities in the slurry. For other non-metallic Impurities cannot be removed

In the patent with the patent number ZL201120409615.1, the applicant set up an impurity removal device in the papermaking material preparation process, and used negative pressure and wind to change the raw material conveying method to remove impurities in the raw material. This method can remove heavy impurities in the raw material. Impurities, but the impurities mixed in the slurry cannot be removed during the transportation process, and the purity of the slurry entering the mill cannot be guaranteed
