Description

Technical Field

[0001] This utility model relates to the field of septic tank technology, specifically a modular plastic septic tank with a quick-assembly structure. Background Technology

[0002] A septic tank is a facility for treating domestic sewage. Traditional septic tanks are made of concrete or brick. However, after long-term use, due to the corrosion of sewage, concrete and brick septic tanks are prone to leakage and other problems, resulting in high maintenance costs. Because plastic septic tanks are lightweight, corrosion-resistant, and easy to install, their use is becoming increasingly widespread.

[0003] Currently, plastic septic tanks are usually designed as a single unit. However, a single-unit plastic septic tank takes up a lot of space and has high transportation costs during transportation and installation. While assembled plastic septic tanks solve the transportation cost problem by splicing together the components, the assembled plastic septic tank has insufficient sealing and the assembly process is complex, which affects the installation efficiency. Utility Model Content

[0008] Preferably, a positioning hole is provided through the surface of the lower connecting strip, and a positioning rod is engaged with the inner wall of the positioning hole. The positioning rod is fixedly connected to the lower surface of the upper connecting strip. There are 4 sets of positioning rods and positioning holes, and the 4 sets of positioning rods and positioning holes are respectively located at the four corners of the upper and lower connecting strips.

[0009] By adopting the above technical solution, positioning holes and positioning rods can be used to assist in docking during the installation process.

[0010] Preferably, a connecting block is fixedly installed on the outer surface of the upper connecting strip, and a connecting bolt is threadedly connected to the surface of the connecting block. The lower end of the connecting bolt is connected to a threaded hole provided on the surface of the connecting groove. The connecting groove has an L-shaped cross-section and is fixedly connected to the outer surface of the lower connecting strip.

[0011] By adopting the above technical solution, the upper shell and the lower shell can be connected by using the connection groove and the connection bolt.

[0012] Preferably, the upper and lower shells are provided with a partition structure, which achieves spatial division inside the septic tank through limiting blocks and partitions.

The outer surface of the limiting block is fixedly installed on the inner wall of the upper shell. Two parallel limiting blocks form a group, and the gap between the two limiting blocks is marked as a slot structure. Two groups of limiting blocks are provided, and the two groups of limiting blocks are arranged parallel to each other on the inner wall of the upper shell. The two groups of limiting blocks divide the interior of the upper shell into three chambers. The same partition structure is symmetrically arranged on the inner wall of the lower shell. A partition plate is engaged and connected in the slot structure formed by the limiting blocks. The partition plate is a circular plate structure, and a connecting pipe is provided through the surface of the partition plate. The connecting pipe is an L-shaped structure.
