Abstract
An automatic control system for water of amino plastic comprises at least one net belt drying box for amino plastic production. A temperature and water sensor is arranged in the drying box and connected with a PC so that temperature and water information in the drying box can be received. The drying box is provided with an air conveying pipe which communicates with the interior of the drying box and is provided with a flow control valve. A steam heat exchanger and a cooling water heat exchanger are arranged on the air conveying pipe. The air conveying pipe can make air and steam be subjected to heat exchange through the steam heat exchanger, the air is heated to form hot air, or the air and cooling water are subjected to heat exchange through the cooling water heat exchanger, and the air is cooled to form cold air. A steam gas valve is arranged on a steam flow channel of the steam heat exchanger, and a cooling water valve is arranged on a cooling water pipe of the cooling water heat exchanger. The flow control valve, the steam gas valve and the cooling water valve are connected to the PC so that the valves can be controlled to be switched on, switched off or the sizes of the valves can be controlled. The automatic control system has the beneficial effects of being simple in structural composition, convenient to use and operate and capable of effectively controlling temperature and the water and improving the production efficiency of the amino plastic and the like.
Description
Technical field
What the present invention relates to is a kind of aminoplast moisture content automatic control system, is mainly used in aminoplast production mesh-belt baking oven, belongs to the control technology field of aminoplast moisture content.
Background technology
Aminoplast dry is after heat exchanger, to produce hot-air to pass into and in baking oven, heat aminoplast by steam, thereby commonly add thermal control and take traditional valve control steam flow hand-manipulated to reach temperature control object, but owing to being manual operation, therefore not only labour intensity is large, and temperature control poor effect, especially the moisture content in uncontrollable baking oven in temperature control, causes the production effect of aminoplast to reduce, the existence of the defects such as poor product quality.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and provide a kind of structure composition simple, use easy to operately, can effectively control temperature and moisture content, improve the aminoplast moisture content automatic control system of aminoplast production efficiency.
The object of the invention is to complete by following technical solution, a kind of aminoplast moisture content automatic control system, it comprises at least one mesh-belt baking oven for aminoplast production use, in described baking oven, be provided with temperature and moisture sensor, described temperature and moisture sensor are connected to a PC to receive temperature and the moisture content information in baking oven; Described baking oven dispose be communicated with in baking oven, with the air delivery pipe of flow control valve, on described air delivery pipe, be respectively arranged with vapor heat exchanger and cooling water heat exchanger, air delivery pipe wherein can make air and steam carry out heat exchange by vapor heat exchanger respectively to add hot-air and become hot-air or make air and cooling water carry out heat exchange cooling-air by cooling water heat exchanger and become cold air; On the steam flow channel of described vapor heat exchanger, be provided with steam air valve, and on the cooling water pipe of described cooling water heat exchanger, be provided with cooling water valve, described flow control valve, steam air valve and cooling water valve be connected to described PC with the unlatching of by-pass valve control, close or size.
As preferably: electrothermal heater is installed in described baking oven, and the power source circuit switch of described heater is connected with described PC, described vapor heat exchanger is connected together successively with cooling water heat exchanger and the steam air valve that passes through is separately connected with PC with cooling water valve, carry out the control of air themperature in air delivery pipe, and carry out the moisture control in baking oven by the control of temperature; Described PC be existing can be by after receiving temperature and moisture content information and carrying out normal value contrast and then control the intelligent PC of multiple electric control valves.
The invention belongs to the one of prior art is improved, it is simple that it has structure composition, uses easy to operately, can effectively control temperature and moisture content, improves the features such as aminoplast production efficiency.
