Gate casting die for biogas digester

Abstract

The invention discloses a gate casting die for a biogas digester. The gate casting die for the biogas digester comprises a gate inner die and a gate outer die, wherein the gate inner die is arranged in the gate outer die; the gate outer die comprises a feeding opening outer die and a discharging opening outer die; the gate inner die comprises a feeding opening inner die and a discharging opening inner die; the feeding opening inner die is arranged in the feeding opening outer die; and the discharging opening inner die is arranged in the discharging opening outer die. By the gate casting die for the biogas digester, the kinds of consumable items required by construction can be reduced, the construction period is shortened, and leakage between a feeding opening and a top cover of the biogas digester and leakage between a discharging opening and the top cover of the biogas digester can be effectively eliminated.

Description

technical field [0001] The invention relates to a pouring mold for a feed port of a biogas pit, in particular to a mold used for pouring the feed port and the discharge port in the construction of a biogas pit. Background technique [0002] In recent years, the development of rural biogas has achieved remarkable energy, economic, ecological and social benefits, and has become an important part of building a new socialist countryside. The biogas digesters for biogas production have played a huge role in energy output, economic benefits and ecological benefits due to their advantages of energy saving, income increase and emission reduction. The current construction method of the biogas digester is mainly to use concrete to pour the biogas digester body through the mold. After the concrete is completely collected, the brickwork shall be carried out by hand, and then painted. Although this way of using bricks to build the inlet and outlet of the biogas digester can realize the...

AI Technical Summary

Problems solved by technology

Although this way of using bricks to build the inlet and outlet of the biogas digester can realize the overall construction of the biogas digester, but in the actual construction process, because of the use of bricks, the variety of materials has increased, resulting in difficulties in procurement and transportation. It is troublesome; and the construction of the feed port and the discharge port cannot be carried out until the concrete for pouring the biogas tank body is completely collected. Leakage often occurs between the bottom brick of the feed port and the discharge port and the top cover of the biogas tank due to incompatibility

Obviously, the method of bricking the material inlet and outlet has the disadvantages of many kinds of consumable materials, long construction period, and inability to completely cut off the leakage
