Abstract
The utility model relates to an improved moisture controllable drying machine for producing a corn alcohol trough, belonging to drying machine equipment; a feed port and a dry powder outlet of a tube pass are arranged on a tubular drying machine, and a steam inlet, a secondary steam outlet, a condensed water outlet and a secondary steam outlet of a shell pass are connected with a fan. The improved moisture controllable drying machine is characterized in that a temperature monitor connected with the drying machine shell pass is in signal connection with the fan connected with the secondary steam outlet, the fan is a variable frequency fan, and a pressure monitor connected with the drying machine shell pass is in signal connection with a steam adjusting valve at the drying machine steam inlet. In the utility model, the temperature and the pressure of the shell pass of the dying machine can be controlled in a certain range, the moisture in the product dried by the drying machine can be effectively and stably controlled, the quality of the product can be improved, the operation intensity of the operation personnel can be reduced, and the economic benefit of enterprises can be increased.
Description
Technical field
The utility model belongs to drier unit, refers in particular to a kind of improved drying machine that can control output product moisture content automatically of corn alcohol groove production usefulness.
Background technology
Produce DDGS enterprise with maize alcohol lees, to have floor space little because of the shell and tube drying machine, the mechanization degree height, and advantage such as the indirect steam that dry run produces is recycling is adopted by most of enterprise.The drying machine tube side is walked material, is provided with the outlet of charging aperture and dry powder, and shell side is flat, is provided with steam inlet, indirect steam outlet and condensate water outlet, and the indirect steam outlet is communicated with blower fan.The wet poor and part dry powder that is produced by centrifuge, the evaporation underflow enters drying machine after batch mixer fully mixes dry operation, discharge dry powder after reaching certain moisture, the part of dry powder is got back to the batch mixer of drying system to regulate the water intake machine branch by a rotary valve, a part is discharged as finished product.The control of drying machine finished product moisture content, be that by virtue of experience (feel) and finished product are chemically examined afterwards and learnt fully, there are not data and rational method of operating as support, product quality is decided by employee's experience technical ability, therefore, this finished product moisture content control is that each enterprise is difficult to hold always, even have the experienced operator of certain operating experience, also not exclusively can be controlled at moisture within the index, in most cases, it is a mean value, and in bulk product, moisture is a mean value, the existing product that is lower than standard moisture, the product that is higher than standard moisture is also arranged, within a certain period of time, have phenomenon such as go mouldy and take place.
Summary of the invention
The utility model provides a kind of controlled drying machine of improved moisture content of corn alcohol groove production usefulness, to improve the quality of products just in order to overcome above-mentioned deficiency.The main improvement is to set up a drying machine shell side temperature monitor, described drying machine shell side temperature monitor signal connects the frequency conversion fan that joins with the outlet of drying machine indirect steam, set up a drying machine shell side pressure monitor again, described drying machine shell side pressure monitor signal connects drying machine steam inlet control valve.Specifically implement like this: a kind of controlled drying machine of improved moisture content of corn alcohol groove production usefulness, be equipped with charging aperture, the dry powder outlet of tube side on the shell and tube drying machine, the steam inlet of shell side, indirect steam outlet, condensate water outlet, the indirect steam outlet links to each other with blower fan, it is characterized in that a temperature monitor signal that links to each other with the drying machine shell side is connected the blower fan that joins with the outlet of drying machine indirect steam, described blower fan is a frequency conversion fan, and a pressure monitoring instrument signal that links to each other with the drying machine shell side is connected the steam control valve of drying machine steam inlet.
Under the relatively stable situation of external condition, the indirect steam physical index that drying machine produces is metastable, but when owing to a certain condition fluctuation taking place, evaporated water can change thereupon, corresponding the changing of temperature of drying machine shell side steam is according to drying machine shell side variation of temperature scope, by the temperature measuring conversion equipment, obtain the frequency of output signal control air exhauster, reach control drying machine shell side temperature within the specific limits.
Under the relatively stable situation of external condition, the feed conditions of drying machine changes, evaporated water can change thereupon, the drying machine shell side pressure, the corresponding generation fluctuation of the dividing potential drop of steam is according to the excursion of drying machine shell side pressure, by the piezometry conversion equipment, obtain output signal, regulate and control the heating steam inlet of drying machine, reach control drying machine shell side pressure within the specific limits.
The utility model is by setting up drying machine shell side temperature monitor and pressure monitoring instrument, make the shell side temperature and the shell side pressure of drying machine all within the specific limits controlled, thereby effectively also stably controlled the product moisture of drying machine, improved the quality of product, reduce personnel operation intensity, increased economic benefit of enterprises.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
A kind of controlled drying machine of improved moisture content of corn alcohol groove production usefulness, be equipped with charging aperture 1, the dry powder outlet 2 of tube side on the shell and tube drying machine, the steam inlet 3 of shell side, indirect steam outlet 4, condensate water outlet 5, indirect steam outlet 4 links to each other with frequency conversion fan 9, one temperature monitor 6 signals that link to each other with the drying machine shell side are connected the steam control valve 8 that pressure monitoring instrument 7 signals that link to each other with the drying machine shell side with drying machine indirect steam outlet 4 frequency conversion fans that join 9, are connected drying machine steam inlet 3.
