The invention discloses a primary sewage treatment tank, which comprises a box body, a filter chamber formed by the box body, a box cover sealed and fixed with the box body on the upper side, a water inlet hole, a sewage discharge hole and a water outlet formed on the box body, a transverse plate fixed in the filter chamber, a plurality of rows of holes through the right end of the transverse plate formed, a baffle rod is sleeved in the through hole, and the lower end of the baffle rod is pressed against the lifting plate. The right side wall, the front side wall and the back side wall of the lifting plate are respectively pressed against the inner wall of the filter chamber. The lifting plate is equipped with an adjusting mechanism that drives it to move up and down. The upper end of the baffle rod is fixed on the floating plate. There are several springs fixed on the floating plate, and the upper end of the spring is pressed on the box cover. A filter net is fixed between the inner wall of the box cover and the filter chamber, and the filter net is located above the transverse plate. The invention can effectively separate solid impurities, such as residues, without clogging the filter screen, and is convenient for cleaning solid impurities.

一种初级污水处理箱
:本专利技术涉及污水处理
,具体涉及一种初级污水处理箱。
技术介绍
:含有不溶物、大颗粒沙子、石子、残渣等固体杂质的污水在进入后续生化处理工艺前,需要将这些对生化反应有影响的固体杂质脱除。现有的技术是一般是通过滤网对不溶物、大颗粒沙子、石子、残渣等固体物质进行过滤,这样这些固体杂质容易堆积在滤网上,造成对滤网的堵塞,且滤网清理起来较为麻烦。
技术实现思路
:本专利技术的目的是克服现有技术的不足,提供一种初级污水处理箱,它可以对残渣等固体杂质进行有效分离,且不会对滤网造成堵塞,方便清理固体杂质。本专利技术解决所述技术问题的方案是:一种初级污水处理箱,包括箱体,所述箱体成型有上侧开口的过滤腔,过滤腔的上侧设有与箱体密封固定连接的箱盖,所述箱体的右侧壁的下端成型有与过滤腔相通的进水孔和排污孔,所述进水孔密封连接有进水管,排污孔螺接有螺塞,所述箱体的左侧壁的上端成型有与过滤腔相通的出水孔,出水孔连接有出水管,所述过滤腔的左侧内壁上固定有横板,横板的前侧壁和后侧壁分别压靠在过滤腔的内壁上,所述横板的右端成型有多排上下贯穿的通孔,通孔内套接有挡杆,挡杆穿 ...
