1, the design basis

1) feed mill feed store In the finished package, the storage time is _3_ 天; the storage time in the pig farm is _6_ days; guarantee the freshness of feed and the control of feed transport in the field, and the pig farm feed is sufficient, and the harsh weather is prevented. Feed transportation problem.
2) Feed varieties

(7) Heating system equipment design standard

1. Design content

The content of the pig farm heating design is composed of three parts: heating mode, heating energy and heating equipment.
1) Heating mode: replacing the coal furnace, hot blast furnace distribution heating mode, reducing energy loss, reducing cost, and increased energy efficiency.
2) Heating energy: fuel uses environmentally efficiency energy such as biomass, natural gas, petroleum liquefied gas, improve heating efficiency of heating system;

3) Heating equipment: heat sink, floor heating control Key components such as electromagnetic valves use imported equipment to ensure safe, efficient, high temperature control, and improve system service life.
3, the design is based on

The model is built by energy conservation law, “need to be complementary heat = building loss calories + ventilation loss heat – pig stroke heat”, indoor heat control determines changes in indoor temperature . The purpose of warming warmth can be achieved by increasing the insulation performance of building materials.

In the cold season, the pig house is equipped with heating equipment, and the indoor temperature is in the comfort of the pig. See the table below.

Space Heater (8) Hydropower System Design Standard

1, Design Principle

1) The main circuit is TN-S Power supply system, the audience circuit line adopts RVV, BVV and other national standard copper wire cable, prevent electric shock to ensure safety. The renewal water system uses PVC water pipes, set along the sky flower, improves installation efficiency, laying aesthetics; configures the pressure reducing valve to ensure that the water pressure is stable, saves water.

2) Leakage switch, wire and cable use Snney and other foreign high-quality brands to ensure system safety and stabilize operation. 2, Hydropower System Technology Design

Signal Water Wire Production Area Water Tower Water, through the outer tube to each house, the water pipe is filtered through the filter, and the pressure reducing valve is reduced pressure. Enter the house, connect the faucet and water. The power supply is reached by the electric wire, and the main wire is added to the main leakage switch, and the electric wire is divided into the internal equipment from the main leakage switch. Wastewater area
3, hydropower system equipment configuration

Pig house drinking water system lighting field main circuit insulation circuit generator with Huandian 1) Positioning bar configuration water level meter, one per 25 meters; 2 ) Shot of the sow configuration of the roller water treatment; childbirth home sow, boar brill configuration rollingWater dispenser, piglets to configure a small bowl of drinking aeter. 3) Fertilization house, the production of the drug consumption per unit, and each unitary sow and piglets separately separate the water supply system. 4) All connecting PPR main water pipes and galvanized pipe pipes are hoses, hoses are 16 * 12PVC polyester fiber reinforced hoses, pressure ≥ 0.8 MPa, and copper joints. 5) Surface water pipes in severe cold areas below the frozen soil. 6) Fire and pig houses can share a pipeline; one waterproof tube is arranged every 16m2, and the waterproof tube power is 36W /. It is required to increase the light intensity of the light to increase the lighting in the pig head in the breeding area to enhance the childbirth rate; other pig houses are not less than 100 LUX. The main circuit is set by overhead, and use copper core wires The three-phase five-wire system is used, and each pig house is configured to configure a separate circuit breaker. Configure a socket for each branch page, and the socket is configured. 80,000 scale, 1 200KW + 1 600KW generator. 1 200KW generator is used to ensure the lowest ventilation requirements of the pig house, and another 600KW generator is used in the case of satisfying the full load power.
