[0002] Household septic tanks can be divided into cement tube septic tanks and plastic septic tanks based on different materials. The size of the septic tank is determined according to the population of each family, which can be divided into 0.5m³, 0.8 m³, 1.0 m³, 1.2 m³, 1.5 m³, 2.0 m³, etc., the existing plastic septic tanks are made of two elliptical long grooves by injection molding. Due to the large size and specifications and the large volume of injection molded parts, there is a large investment in injection molds, especially the need Large (tens of thousands of grams) injection molding machine, high processing costs

Embodiment Construction
[0021] The present invention relates to a kind of processing method of segmental self-heating connected plastic septic tank, such as figure 1 — Image 6 As shown, it is characterized in that: it is composed of a hemispherical head pipe 1 and a circular pipe section 2, and a resistance sheet 3 is arranged in the hemispherical head pipe 1 and the circular pipe section 2, and the resistance sheet 3 is energized, heated and pressurized to turn the hemispherical head The pipe 1 and the circular pipe section 2 are integrated into a septic tank, the circular pipe section 2 is provided with a compartment 4, the compartment 4 is provided with a partition 5, and the partition 5 is formed with a through hole 6, and the processing steps are as follows:
[0022] The first step is to process the hemispherical head pipe, using an injection molding machine and an injection mold to process the plastic raw material into a hemispherical head pipe;
[0023] The second step is to process the circ...

The invention relates to a machining method of a sectioned self-heating connection type plastic septic tank. The septic tank comprises a hemispheric head pipe and a round pipe section, wherein resistor discs are arranged in the hemispheric head pipe and the round pipe section, and are electrified, heated and pressurized to integrally connect the hemispheric head pipe and the round pipe section to form the septic tank; and partition grooves are formed in the round pipe section, partition boards are arranged in the partition grooves, and through holes are formed in the partition boards. The machining method comprises the steps of machining the hemispheric head pipe, the round pipe section and the partition boards, mounting the partition boards and the resistor discs, clamping and fixing the hemispheric head pipe and the round pipe section, heating, connecting, and carrying out acceptance check. By virtue of the technical scheme, the plastic septic tank can be produced only by two molds, one mold is used for machining the hemispheric head pipe, and the other mold is used for machining the round pipe section; furthermore, the septic tank can be provided with multiple round pipe sections, various specifications of septic tanks can be produced, the molds for machining the hemispheric head pipe and the round pipe section are small in volume and low in cost, and the investment cost is saved; and by machining by virtue of a small-sized injection molding machine, the production cost can be lowered.
