Description

Technical Field

[0001] The utility model relates to the technical field of septic tanks, in particular to a cement combined septic tank with an anti-seepage function. Background Art

[0002] Septic tanks are equipment that treats feces and filters and precipitates them. The principle is that the solidified matter decomposes at the bottom of the tank, and the hydrated matter on the upper layer flows into the pipe, preventing the pipe from being blocked and giving the solidified matter (feces and other garbage) enough time to hydrolyze. Septic tanks refer to small treatment structures that separate and precipitate domestic sewage and perform anaerobic digestion of sludge; cement-combined septic tanks are septic tanks built on cement.

[0003] Public document: CN210238739U, a prefabricated cement component anti-deformation and anti-leakage septic tank, including a tank seat, a partition and a pipe system. The tank seat is divided into three chambers by four partitions. Two adjacent chambers are connected by an internal overflow pipe that runs through the two internal partitions. An inlet pipe and an external overflow pipe are installed on an outer partition, and an outlet pipe is installed on the other partition. The inlet pipe, the internal overflow pipe, the external overflow pipe and the outlet pipe together constitute a pipe system; two first convex plates are symmetrically arranged on one side of the partition, and the inner wall of the tank seat is symmetrically arranged with a second convex plate. The first convex plate, the corresponding second convex plate and part of the partition and the tank seat form a cement filling hole. The structural design of the cement filling hole of the utility model is scientific and reasonable, and only a small amount of cement filling is required to improve the sealing effect of the partition, while also increasing the supporting strength of the partition; the utility model has the advantages of anti-leakage, anti-deformation, easy assembly and easy construction.

[0004] The above-mentioned existing septic tank adopts prefabricated components to improve the anti-leakage effect of the septic tank. However, the main body of the septic tank and the internal partition are both single anti-permeability structures. Once the internal contact surface is aged, it is easy to cause the entire anti-leakage function to decline, and the partition structure cannot be convenient for users to disassemble and remove after leakage damage, and needs to be replaced as a whole, increasing the economic cost; therefore, it does not meet the existing needs. In this regard, we propose a cement composite septic tank with anti-seepage function. Utility Model Content

[0010] Preferably, an overflow port for liquid flow is provided on the outer wall of the partition, and an inlet pipe and a discharge pipe are respectively installed at both ends of the septic tank body.

[0011] Preferably, a cover plate is detachably mounted on the top of the septic tank body through an assembly part, and a plurality of exhaust pipes are provided on the upper surface of the cover plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model can divide the main body of the septic tank into three parts, namely, inner, middle and outer parts, by arranging an outer prefabricated steel plate, a cement reinforcement layer and an inner prefabricated steel plate. The cement reinforcement layer is used to reinforce and connect the two steel plate layers. The outer prefabricated steel plate acts on the outside, and the inner prefabricated steel plate acts on the inside. Both surfaces are sprayed with water-resistant and corrosion-resistant coatings to improve their own performance. The cement septic tank is strengthened with an inner, middle and outer three-layer structure to prevent leakage of the septic tank. Even if the inner prefabricated steel plate is affected and damaged, the cement reinforcement layer and the outer prefabricated steel plate in the middle can still achieve anti-seepage, thereby improving the overall anti-seepage effect of the septic tank. By arranging an outer steel plate frame and an inner filling cement layer, the partition can have higher deformation resistance and better permeability than traditional prefabricated partitions, thereby improving the anti-seepage effect at the partition.

[0014] 2. Both ends of the partition are located in the U-shaped groove of the assembly frame. The assembly frame has the effect of restricting the partition. The upper part of the assembly frame is the opening of the U-shaped groove, which is used to facilitate users to take out and replace the partition. The user can use the handle to pull the partition upward to move it upward, so that the partition is detached from the upper opening of the assembly frame, thereby facilitating users to replace the partition. Compared with the overall prefabrication type, the replacement process only needs to replace the damaged part, and there is no need to replace all of it. The overall replacement cost is low and the replacement operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS
