Description
本新型是有關於一種紙漿篩選網,特別是指一種適用於篩濾高濃度紙漿的紙漿篩選網。The present invention relates to a pulp screening net, and more particularly to a pulp screening net suitable for screening high concentration pulp.
參閱圖1與圖2,習知的一種紙漿篩選網1,如中華民國新型專利編號第537324號所示,適用於進行攪拌篩選顆粒較大(如再生紙)的紙漿。Referring to Figures 1 and 2, a conventional pulp screening screen 1, as shown in the Republic of China New Patent No. 537324, is suitable for agitating and screening large pulp (e.g., recycled paper) pulp.
該紙漿篩選網1包含數個間隔排列的定位框11及數個垂直設置於該等定位框11並間隔排列的篩片12,每兩兩相鄰的篩片12之間形成一篩口13。該等定位框11分別包括一內壁面111及數個間隔形成於該內壁面111的插槽112。該等篩片12分別包括一頭部121及一插設入相對應的插槽112並將該等定位框11串接的根部122,且該根部122與相對應的插槽112形成倒鉤狀地緊密結合。The pulp screening screen 1 comprises a plurality of spaced-apart positioning frames 11 and a plurality of screens 12 arranged vertically and spaced apart from each other, and a screen opening 13 is formed between each two adjacent screens 12. The positioning frames 11 respectively include an inner wall surface 111 and a plurality of slots 112 formed at intervals on the inner wall surface 111. The screens 12 respectively include a head portion 121 and a root portion 122 that is inserted into the corresponding slot 112 and connects the positioning frames 11 in series, and the root portion 122 forms a barbed shape with the corresponding slot 112. The ground is tightly integrated.

The slots 112 are detached. However, the heads of the screens 12 respectively have a screen surface 123 facing the stirring vortex and inclined, and the screens 123 form an angle which can only match the direction in which most of the pulp is agitated. But located near the screens 123 Part of the pulp cannot be uniformly mixed. When the high-concentration pulp is sieved, the stirring force of the sieves 12 is still insufficient, thereby causing incomplete screening.
因此,本新型之目的,即在提供一種適用於篩濾高濃度紙漿的紙漿篩選網。Therefore, the object of the present invention is to provide a pulp screening screen suitable for screening high concentration pulp.
於是本新型紙漿篩選網,包含數個上、下等間隔排列的環形定位框及數個篩片。Therefore, the novel pulp screening net comprises a plurality of annular positioning frames arranged at upper and lower intervals and a plurality of sieve sheets.
該等定位框分別包括一圍繞界定出一篩濾空間的內壁面、一相反於該內壁面的外壁面,及數個等間隔形成於該內壁面的插槽。The positioning frames respectively include an inner wall surface defining a screen space, an outer wall surface opposite to the inner wall surface, and a plurality of slots formed at equal intervals on the inner wall surface.
每一插槽具有一形成於該內壁面的小槽段及一由該小槽段朝該外壁面延伸且槽寬大於該小槽段的大槽段。Each slot has a small slot section formed on the inner wall surface and a large slot section extending from the slot section toward the outer wall section and having a slot width greater than the slot section.
該等篩片間隔排列於該等定位框的內壁面,並插設入由上至下的相對應插槽以串接每一定位框。The screens are arranged at intervals on the inner wall surface of the positioning frame, and are inserted into corresponding slots from top to bottom to connect each positioning frame in series.
該等篩片分別包括一頭部及一根部,該頭部面向該篩濾空間且具有一凹穴,該根部由該頭部束縮且與相對應的插槽緊密結合。The screens each include a head portion and a portion facing the screen space and having a recess that is bundled by the head and tightly coupled to the corresponding slot.
每兩兩相鄰之該等篩片的根部與上、下二層定位框相配合界定出一篩口。The root of each of the two adjacent screens cooperates with the upper and lower two positioning frames to define a screen.
本新型之功效在於:藉由該等凹穴提升擾流的效果,使得位於該等凹穴附近的紙漿混合更均勻,而適用於進行高濃度紙漿的篩濾。The effect of the novel is that the effect of lifting the spoiler by the recesses makes the pulp mixing in the vicinity of the pockets more uniform and suitable for the screening of high-concentration pulp.
