Abstract
The utility model discloses a waste paper pulp impurity separating device. A separating area of the waste paper pulp impurity separating device is a double inverted-cone pipeline. The double inverted-cone pipeline comprises an upper inverted-cone cavity and a lower inverted-cone cavity. The circular diameter of the top surface of the upper inverted-cone cavity is larger than that of the bottom surface thereof, the circular diameter of the top surface of the lower inverted-cone cavity is larger than that of the bottom surface of the upper inverted-cone cavity, and the side wall of the upper inverted-cone cavity is provided with a detachable ceramic layer. By the waste paper pulp impurity separating device in the double inverted-cone structure, paper pulp can be separated twice, impurity separation effect is fine, subsequent maintenance of the separating device is simplified by the aid of the detachable ceramic layer, the service life of the separating area of the separating device is prolonged, maintenance cost is reduced and practicality is high.
Description
Technical field
The utility model relates to the old paper stock purification apparatus, is specifically related to a kind of secondary stock impurity separating device.
Background technology
In the production process of paper industry paper pulp, be the recycling that the papermaking of raw material reslurry has realized the paper fiber with waste paper, but inevitably can contain heavy seeds such as metal, sand, stone, glass in the secondary stock.To have a strong impact in order the quality that becomes paper not being caused, to guarantee the normal operation of machinery equipment in the subsequent technique, must use the secondary stock scummer that heavy seeds and paper pulp are separated.
HC Cleaner is to produce one of secondary stock impurity separating device of usefulness in producing, and existing scummer generally comprises slurry intake chamber, impurity Disengagement zone, recoil water water pipe, sediment jar and corresponding pulp inlet/oulet and slag-drip opening.Wherein the impurity Disengagement zone is the cylinder pipeline or the back taper pipeline of a lined ceramics vertebral body.Its shortcoming is: the impurity separating effect is not ideal, and the pulp processing amount is big, and feed pressure is many, and flow rate of slurry is fast more than 3KPa, because the impurity in the slurry is more, to the duct wall serious wear of Disengagement zone, the Disengagement zone is shorter service life, and maintenance cost is high.Therefore, be necessary existing secondary stock impurity separating device is carried out architecture advances.
The utility model content
The purpose of the utility model is to overcome the defective that exists in the prior art, and a kind of secondary stock impurity separating device of impurity good separating effect rational in infrastructure, easy to maintenance is provided.
For realizing above-mentioned purpose; The technical scheme of the utility model is a kind of secondary stock impurity separating device of design; The Disengagement zone of secondary stock impurity separating device is two vertebral body pipelines, and two vertebral body pipelines comprise vertebral body cavity and following vertebral body cavity, and the end face circular diameter of last vertebral body cavity is greater than the bottom surface circular diameter; The end face circular diameter of following vertebral body cavity is greater than the bottom surface circular diameter of last vertebral body cavity, and the sidewall of last vertebral body cavity is provided with detachable ceramic layer.
In order to make detachable ceramic layer structure simple, easy to make, optimized technical scheme is that detachable ceramic layer comprises ceramic cylinder and the loading and unloading bracket that is fixedly connected on the ceramic cylinder upper end.
For the impulsive force of the slowing down impurity particle influence to pipeline, optimized technical scheme is to be provided with cushion between the sidewall of ceramic cylinder and last vertebral body cavity.
For the ease of the section displacing ceramic cylinder, further reduce maintenance cost, optimized technical scheme is that ceramic cylinder is made up of several inverted conical shape segmentations.
For fear of wearing and tearing because of vibration equipment produces between the segmentation, optimized technical scheme is to be provided with sealing ring between the adjacent inverted conical shape segmentation.
In order to be that sealing ring has certain ABRASION RESISTANCE and sealing, optimized technical scheme is that sealing ring is processed by flexible wear-resistant material.
The advantage and the beneficial effect of the utility model are: this separator adopts two inverted pyramidal structures; Paper pulp is carried out separating treatment twice; Impurity good separating effect, detachable ceramic layer have been simplified the follow-up maintenance of device, have prolonged the service life of device Disengagement zone; Reduced maintenance cost, practical.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technical scheme of the utility model, and can not limit the protection domain of the utility model with this.
Like Fig. 1, Fig. 2 and shown in Figure 3; The utility model is a kind of secondary stock impurity separating device; The Disengagement zone 4 of secondary stock impurity separating device is two vertebral body pipelines, and two vertebral body pipelines comprise vertebral body cavity 9 and following vertebral body cavity 10, and the end face circular diameter of last vertebral body cavity 9 is greater than the bottom surface circular diameter; The end face circular diameter of following vertebral body cavity 10 is greater than the bottom surface circular diameter of last vertebral body cavity 9, and the sidewall of last vertebral body cavity 9 is provided with detachable ceramic layer.
In the present embodiment, detachable ceramic layer comprises ceramic cylinder 11 and the loading and unloading bracket 12 that is fixedly connected on the ceramic cylinder upper end.
In the present embodiment, be provided with cushion 13 between the sidewall of ceramic cylinder 11 and last vertebral body cavity 9.
In the present embodiment, ceramic cylinder 11 is made up of several inverted conical shape segmentations 14.
In the present embodiment, be provided with sealing ring 15 between the adjacent inverted conical shape segmentation 14.
In the present embodiment, sealing ring 15 is processed by flexible wear-resistant material.
Slurry has stock inlet 1 to get into the secondary stock impurity separating device; Forming stable eddy flow through slurry intake chamber 3 along inwall; Arrive Disengagement zone 4; 4 carry out the elutriation of artesian water by recoil water water pipe 5 in the Disengagement zone, are that the small amount of fibers that contains in the impurity is returned the scummer top again, arrive subsequent processing with good slurry mouthfuls 2.Then operated pneumatic valve 6 enters into sediment jar 7 to impurity through top, discharges through bottom operated pneumatic valve 8 batch (-type)s, accomplishes purification process.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
