Background

With the development of society and the improvement of living standard of people, the demand of meat, eggs and milk is continuously increased, and the breeding scale is continuously enlarged. The excrement produced in the breeding process mainly comprises livestock and poultry excrement, urine and sewage, and if the excrement cannot be effectively treated, the pollution to air, soil, water sources and human living environment can be caused, and meanwhile, the growth and development of livestock and poultry individuals and the disease control can be influenced.

The solid-liquid separation technology of the excrement can effectively separate the excrement into dry matters and sewage, the excrement is convenient to manage after being separated, and collection, storage, treatment and harmless utilization are facilitated; for example, the dry matter can be used for manufacturing biological organic fertilizer, the sewage can be used for producing liquid fertilizer or other auxiliary materials are added for manufacturing methane.

Disclosure of Invention

The utility model mainly solves the technical problems that: the drum-type solid-liquid separator makes the water in the excrement separated from the dry solid matter of solid particles in the excrement in a spiral extrusion mode, thereby realizing the purpose of solid-liquid separation. The separating drum sieve is a key component in the drum-type solid-liquid separator, and directly influences the quality and the operating efficiency of solid-liquid separation; the aperture of a separation drum screen of a traditional drum-type solid-liquid separator is fixed, the separation drum screen needs to be replaced when materials with different particles are separated, a side vertical plate on one side needs to be detached, the separation drum screen can be replaced, time and labor are wasted, labor intensity is high, the separation drum screen is easy to block in the working process, the cleaning process is troublesome, and the working efficiency is low; the drum screen mechanism of the drum-type solid-liquid separator can effectively avoid the defects of the traditional drum-type solid-liquid separator.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the drum-type solid-liquid separator drum screen mechanism consists of a side vertical plate I, a side vertical plate II, an inner separation drum screen, an outer separation drum screen, a support rod and a binding belt. The two ends of the external separation drum screen are provided with positioning lugs which are uniformly welded at the two ends of the external separation drum screen, and circular arc-shaped hole grooves for locking bolts are formed in the positioning lugs; rectangular screen holes are formed in the inner separating drum screen and the outer separating drum screen, the distance between each screen hole and each screen hole is larger than the width of each screen hole, and the positions of the rectangular screen holes of the inner separating drum screen and the positions of the rectangular screen holes of the outer separating drum screen correspond to each other; a precompression cylinder is welded on one side of a side vertical plate I, a flange is welded on the end face of the precompression cylinder to be conveniently connected with other mechanisms of the drum-type solid-liquid separator, a material feeding hopper is welded in the middle of the precompression cylinder in the radial upward direction, and a spigot is formed on the other side of the side vertical plate I and used for positioning an inner separation drum sieve and fixing a threaded hole of a positioning lug; a discharge hole is welded on one side of the side vertical plate II, and a spigot is formed on the other side of the side vertical plate II and is used for positioning the inner separating drum sieve and fixing a threaded hole of the positioning lug; the supporting rod is connected with the side vertical plate I and the side vertical plate II, and the acting force of the side vertical plate I and the side vertical plate II is utilized to clamp the inner separation drum sieve to limit the rotation of the inner separation drum sieve; the tightening belt strengthens the radial strength of the inner and outer separating rotary screens and ensures that the inner and outer separating rotary screens are in close contact.

The beneficial effects of the utility model are: traditional drum-type solid-liquid separation machine only has a separation drum sieve, when handling the material of different granules, need change the drum sieve in not aperture, wastes time and energy and influences production efficiency. The drum screen mechanism of the drum-type solid-liquid separator adopts the inner separating drum screen and the outer separating drum screen, and the discharge holes of the inner separating drum screen and the outer separating drum screen are relatively displaced by adjusting a certain angle of the outer separating drum screen, so that the size of a discharge hole is changed, the separation of different granular manure is realized under the condition of not replacing the separating drum screen, and compared with the traditional drum-type solid-liquid separator, the drum screen mechanism of the drum-type solid-liquid separator improves the applicability and is easy to operate.
