I. Overview

This device is composed of a multi -functional installation board (mesh plate) tr--ning platform and power device made by steel plates. Various components, devices and components selected during tr--ning can be easily installed on the mesh board, which is convenient and flexible.

According to the needs of teaching and tr--ning, you can choose different components, devices and components. Different curriculum modules, tr--ning of different projects, wide range of applications for this equipment, and many teaching content and tr--ning items that can be completed. The components, devices and components that have been used are removed from the tr--ning platform to centrally keep it, damage and lose less. A tr--ning place can complete several professional teaching and tr--ning and economics.

The tr--ning table is equipped with leakage protection, overload and circuit protection to ensure personal safety and equipment use.

Flexible, reliable, secure, and economical is the characteristic of this equipment. For schools with small tr--ning venues and restrictions on teaching funding, this equipment is an ideal vocational education tr--ning equipment.

2. Equipment technical indicators

1. Standard: The overall size is 1632mm × 750mm × 1638mm;

2. Materials for tr--ning tablets: steel plate, aluminum alloy structure;

3. Power: 1) Input: Three -phase AC 380V ± 10% 50Hz three -phase and five -line line; 2) fixed communication output: three -phase and five lines 380V interpolation 2 groups, 220V insert 2 groups, 220V socket 4 groups 4 groups 3) The adjustable DC output: 0 ～ 24V/2A continuously adjusted 2 groups (with pointer voltage, pointer current meter monitoring power changes in real time);

4. Interface and instrument: 2 pointer voltage tables, always monitor the power grid voltage change;

5. Protection: The fuse is short -circuit protection, the circuit breaker has overload protection, the leakage switch has leakage protection function, and the current of leakage protection action is ≤30mA.

3. Equipment structure function

The real tr--ning desk consists of three parts: tr--ning screen (built -in power supply), tr--ning table, and tr--ning locker. Taking 30mm × 30mm Founder Steel as the m--n frame material of the equipment; the tr--ning screen and site use the welding connection, and the key parts are used to reinforce the triangular tendon with inner hexagonal screws. The surface is sprayed with high temperature and plastic The role of the two 35mm × 35mm aluminum alloy profiles and slide forms of a mesh board fixed mechanism; below the fixed mechanism is the iron dual -station power box. Device and power output; tr--ning desktop desktop uses 25mm hemp -gray high -density layer plate sealing edge, which effectively improves the insulation level; the bottom of the experimental table is equipped with at least 4 guide wheels to facilitate tr--ning tables to move;

The tr--ning cabinet adopts a standard structure and drawer. There are 3 layers of drawers on the left to store tools and tr--ning materials. The double -pull door design on the right can store two universal hanging boards at the same time. The location of the tr--ning cont--ner can be flexibly adjusted as needed. The size of the shape is: 1300mm × 600mm × 510mm.

1. Experimental purpose:

Organic solid waste composting technology is a commonly used solid waste biological conversion technology, which is one of the important ways to stabilize solid waste and harmless treatment.

Through this experiment, I hope to achieve the following goals:

1. Deepen the understanding of the good oxygen and fertilizer of garbage;

2. Understand the various influencing factors and control measures for the process of piles of garbage and oxygen.

2. Experimental principle:

Good oxygen fertilizer in garbage is under the effect of aerobic conditions to transform organic waste. The soluble organic substances in organic waste can be directly absorbed by microorganisms through microbial cell walls and cell membranes. The insoluble colloidal organic substances are first adsorbed outside the microorganism. Extraceral enzyme secreted by microorganisms is decomposed into soluble substances, and the cells are infiltrated. Microorganisms decompose metabolism and synthetic metabolism through their own life activities, oxidize part of the absorbed organic substances into simple inorganic matter, and release the energy required for biological growth and activities; Microbial reproduction produces more organisms.
