Abstract

The utility model relates to a superhard grinding wheel drying device, including the drying shed, the indoor location of drying shed has the electric heating type's that pair air goes on heating heating device, still is connected with the exhaust device who is used for taking out the room air on the drying shed. The utility model discloses a drying device adopts and directly heats the indoor air of drying shed to room air after will heating is direct discharges with exhaust device, and heating device's heated air is the air in the drying shed always like this, and income is mended to nos new trend, and the difference in temperature of just also having avoided the new trend to bring has reduced heating device's load, and the while has just also reduced the energy consumption of heating device at whole heating period, has reduced the drying cost of emery wheel blank. Simultaneously, along with the pump drainage of airing exhaust the dress, putting, will present low pressure gradually in the drying shed to the disengaging of moisture in the emery wheel blank, the drying efficiency of emery wheel blank with higher speed.

Description

Hard grinding wheel drying unit

Technical field

This utility model is related to a kind of hard grinding wheel drying unit.

Background technology

In production preparation process, the process that free moisture evaporation is discharged in emery wheel is referred to as the dry of emery wheel blank to emery wheel It is dry.Dry purpose is to improve the dry strength of emery wheel blank, is easy to processing before carrying, kiln, inspection, loading of kiln operation, while more may be used Reason moisture content is not too high in cold stage for emery wheel base substrate during ensureing to burn till, and evaporation cracks waste product very much soon.At present, emery wheel A kind of drying unit adopted in drying process vitrified bonded grinding wheel as disclosed in Chinese patent literature CN104654752A is wet Base drying shed, including the body of wall of double layer hollow, the interior wall of body of wall adopts the metope of honeycomb wall, inner wall to be provided with some size phases Same circular hole, in the underground of body of wall hot-air pipeline is installed, and steam pipework is installed at the top of body of wall, and is installed on company on roof The circulating fan being connected on steam pipework.When in use, steam pipework and hot-air pipeline are first opened, using warm-air pipe road direction Interior is passed through dry hot-air and drives indoor steam out of so that after interior is for the recirculated hot air of saturation, will be dried dolly and pushes away Enter interior, be dried operation, in the stage to emery wheel blank drying, by the aperture for adjusting steam pipework, reduce interior and follow The humidity of ring hot-air is evaporating the moisture of emery wheel blank surface.But in because of this drying process, need to drying shed in a steady stream not Disconnected offer hot-air, to ensure the temperature in drying shed, so the heater of hot-air pipeline import need to be continual New air is heated, the energy loss of heater is larger, so that the cost of emery wheel blank drying increases.In addition, Affected by vapor self-contained in new air, hot-air itself the absorbent quantity of steam from emery wheel blank it is limited, Also having led to the drying efficiency of emery wheel blank reduces, and extends the production manufacturing cycle of emery wheel blank, reduces work efficiency.

The content of the invention

This utility model aims to provide a kind of hard grinding wheel drying unit, to solve prior art medium plain emery wheel blank drying energy The too high problem of consumption.

To solve above-mentioned technical problem, the technical scheme of hard grinding wheel drying unit is as follows in this utility model：

Hard grinding wheel drying unit, including drying shed, the indoor location of drying shed has the electrical heating heated to air The heater of formula, is also associated with the air exhausting device for extracting room air out on drying shed.

Air exhausting device include be connected to drying shed roof exhaust duct, the interior of the inlet communication drying shed of exhaust duct, The outlet of exhaust duct is connected with air exhauster.

Roof center position of the import of exhaust duct in drying shed.

Roof of the heater in drying shed, heater has two or more and uniform around the import of exhaust duct.

Being shaped as drying shed is square, and heater has four and office at the roof corner location of drying shed.

Each heater is connected on same control chamber by lead.

Control chamber is provided with the temperature conditioning unit being each correspondingly arranged with each heater.

The body of wall of drying shed and roof are insulation construction.

Drying unit of the present utility model adopts and directly the air in drying shed room is heated, and by after heating Room air is directly discharged with air exhausting device, and the hot-air that adds of such heater is always the air in drying shed, without fresh air Fill into, also avoid the temperature difference that fresh air is brought, reduce the load of heater, while also just reducing heater whole The energy consumption of individual heating period, reduces the drying cost of emery wheel blank.Meanwhile, with air draft dress, the pump drainage put, will in drying shed Low pressure is gradually presented, is disengaged in order to moisture in emery wheel blank, accelerate the drying efficiency of emery wheel blank.

Fig. 2 is the roof structure schematic diagram of drying shed in Fig. 1.

Specific embodiment

The embodiment of hard grinding wheel drying unit of the present utility model：As depicted in figs. 1 and 2, the drying unit includes side The drying shed 1 of shape, the roof of the body of wall of drying shed 1 adopts insulation construction, is provided with drying shed 1 room air is carried out plus The heater 2 and the air exhausting device for pump drainage room air of heat.

Air exhausting device is mainly made up of exhaust duct 3 and air exhauster.The import 31 of exhaust duct 3 is connected to the roof of drying shed 1 Center position, after exhaust duct 3 is drawn from the top of drying shed 1, outlet is connected on air exhauster, to make in the suction of air exhauster With under, the air in the Room of drying shed 1 is extracted out.

Heater 2 is the electrically heated rod installed in the roof of drying shed 1, and heater 2 has four, four heating Device 2 is uniform around the import 31 of exhaust duct 3, while this four heaters 2 are located exactly at the roof corner location of drying shed 1 Place, to heat to room air from the roof corner location of drying shed 1.Four heaters 2 are connected to same control On case 4, in the control chamber 4 four temperature conditioning units 41 electricly connected with each self-corresponding heater 2, each temperature conditioning unit are provided with The thermodetector being also each connected with 41 in the Room of drying shed 1, to obtain the temperature parameter of the correspondence periphery of heater 2, this Sample controllers can according on temperature conditioning unit 41 show temperature parameter adjust manually correspondence heater 2 working condition or By the working condition of the internal controller automatic control heating device 2 of control chamber 4.

The other embodiment of hard grinding wheel drying unit of the present utility model：Heater and/or exhaust duct can also set Put on floor or wall.Air exhausting device may also be only installed in the roof of drying shed and/or wall and/or the row on floor Blower fan.
