Abstract

The utility model relates to a charging hopper drier whose colour can be mixed and which is used for the plastic industry. The utility model is mainly characterized in that a feed charging hopper is additionally arranged on the original charging hopper drier, and a feed advancing mechanism is installed at the middle point of a drier container. The feed advancing mechanism comprises a screw rod and a feed pipe which is sheathed outside the screw rod. One feed return pipe is used to load the material in the container to the feed charging hopper again. Therewith the cycle structure formed causes the material to be lifted, baked and blown for many times. The functions of drying uniformly and sufficiently and color-mixing are obtained. The experiment of a model machine indicates that compared with the existing drier, if the same quantity materials are dried, the time required by the utility model can be shortened more than 40%.

Description

Colour-mixed charging hopper dryer

The utility model relates to a kind of improvement of Hopper Dryer.

In the existing plastics industry, the Hopper Dryer of use mainly is made of the container cover that has steam vent, container and the hot blast conveying mechanism, discharge duct etc. that are installed on container lower side place.During the work of this drier, disposable charging is piled up in container, the hot blast conveying mechanism by the lower side place, dries up with the long period.Because hot blast is to act on material from lower side, thereby is positioned at the bottom part, particularly near the material of lower inner wall, fast drying; And the dry materials on other parts, especially top is slow.Like this, when the dry materials of bottom, the top material still has moisture, dry insufficient, though in order to obtain the material of comparison drying, can grow drying time, the top material is fully dried, but at this moment the higher fusing caking of bottom material Yin Wendu stops up discharge duct, makes troubles for discharging and cleaning container.In addition, this class Hopper Dryer does not possess the function that colour mixture is arranged.

The utility model provides a kind of improved Hopper Dryer, and it can make dry materials evenly, fully, can reach the purpose that shortens drying time again.

The effect that the Hopper Dryer that the purpose of this utility model also is to be provided also has colour mixture.

The purpose of this utility model is finished as follows: fix a screw rod 9 by the bearing block 22,7 and the bearing 21,8 that are installed on support 1 and container cover 4, this screw rod 9 is located in the middle of passing container, outside it feed pipe 10 is housed, the two ends up and down of feed pipe 10 have discharging opening 24 and charging aperture 23; At the charging aperture place one feed hopper is installed, feed hopper and charging aperture intercommunication; The feed back pipe of strap brake door is equipped with in the top of feed hopper, the bottom of container, and the rotation of screw rod is by a motor-driven.When drying machine is worked, the material of pouring into from feed hopper, flow into feed pipe through charging aperture, screw rod not stall under the drive of motor is moving, material in the feed pipe is constantly pushed to the screw rod top, in lifting process, the flowability of self extrusion of materials and material has been taken away part moisture content, when material arrives the top, because the effect of gravity, material drops down onto container, the hot blast effect that sent by the hot blast conveying mechanism, hot-air are taken away moisture content and are discharged through steam vent, simultaneously, material is back to feed hopper by the feed back pipe, enters repetitive cycling once more.When material needs colour mixture, only need close the hot blast conveying mechanism, pour material and colorant into feed hopper, start motor and get final product, at this moment, material and colorant constantly are raised in machine---being scattered---promotes reciprocation cycle, reaches the material purpose mixed mutually with colorant.

Drying machine provided by the utility model is compared with existing Hopper Dryer, owing to adopt material is constantly promoted---be scattered and dry up---loop structure of lifting, thereby dry materials evenly, fully and obviously shorten drying time; The utility model is also because this structure makes it possess the effect that colour mixture is arranged.

Fig. 1 is the longitudinal sectional drawing of a kind of concrete structure of the utility model.

Below in conjunction with accompanying drawing utility model is described in further detail.

With reference to Fig. 1, one has the drying machine container that good heat-insulation layer 12, overcoat 13 and shell have see-through window 14, is that cylindrical shape and bottom are that infundibulate two parts are formed by top.Screw rod 9 with good mechanical strength is fixed in middle place in the container by bearing block 22,7 and the tight cover bearing 21,8 that is installed on support 1 and container cover 4; A feed pipe 10 is adorned so that material is rolled up smoothly to feed pipe 10 tops in the outside of screw rod 9, feed pipe bottom and support 1 welding are fixing, top positions by filling up in the positioning adapter 6 of bearing block 7 bottoms, the two ends up and down of feed pipe have discharging opening 24 and charging aperture 23, feed hopper 20 and charging aperture 23 intercommunications; The rotation of screw rod 9 is driven by the skin wheel apparatus by motor 2, and feed hopper 20 is installed on support 1 relative position with motor 2, so that increase the steadiness of complete machine; Feed hopper 20 is preferably made funnel shaped, make material can be automatically from charging aperture 23 landings in feed pipe 10, in addition, feed hopper 20 disposes a removable cover, both can play insulation effect, can be convenient to get material again and observe in dry run; In order to increase the area that material is subjected to the hot blast effect, reservoir funnel shape part inwall lays a diathermanous fan housing 15, and it is made by the arc sheet metal that is drilled with pore above; Feed back pipe 19 and discharge duct 16 best shared container discharging openings become two branches of same discharging opening.

Claims
