Abstract

The utility model relates to a dehumidifying dryer for plastics, particularly the dehumidifying dryer in which a condensing pipe, a radiator, a fan, etc. are orderly arranged. The dehumidifying dryer can dry air, lead the air to a feeding barrel, and simultaneously add hot wind to plastic particles in the feeding barrel for atomization to cause the surfaces of the plastic particles to be dried. Thus, formed products can be ejected without bad products resulted from moisture or bubbles caused by water content.

Description

The plastic moisture removing drying machine

The utility model is relevant a kind of drying machine, refers in particular to a kind of plastic moisture removing drying machine.

The progress of society, various plastic products are a feast for the eyes, the plastic products major part is then by plastics Jet forming machine ejection formation, therefore, the product confrontation product quality influence of plastic pellet is very big, yet, the quality of plastic pellet can be controlled, its Effect of Environmental then depends on the design of facility, because airborne moisture is attached to the surface of plastic pellet, influence the quality of product, the product quality of plastic molding equipment is given in the design of drying machine, provide a great help, as shown in Figure 1, it is the structure of drying machine commonly used, be provided with a drying machine 2 in the upper end of Jet forming machine 1, the feeding bucket 3 of plastic pellet can be inserted in these drying machine 2 inside, reach one and can impose dry drier 4 plastic pellets in the feeding bucket 3, these drier 4 upper ends are provided with an air blast 5 and air can be introduced in the feeding bucket 3, and send by air outlet 6, so ringing can impose drying to the plastic pellets in the feeding bucket 3, but air still has aqueous vapor, making still has aqueous vapor to be attached to plastic pellet in this way, causes plastics to penetrate finished product and still has problems.

Given this, the inventor also to improve, forms plastic moisture removing drying machine of the present utility model at the shortcoming that exists in the prior art.

Goal of the invention of the present utility model is that air utilizes air blast directly to blow to the feeding bucket in the change prior art, make airborne aqueous vapor adhere to shortcoming on the plastic pellet, utilize the air filter screen middle impurity that deflates earlier, adorn air set pipe then, with airborne condensation of moisture Cheng Shui, and blow in the feeding bucket by fan after with the water in air steam raising by fin, make airborne water moisture be reduced to minimum point.

The technical solution of the utility model is mainly by casing, fan, compositions such as conduit, it is characterized in that: casing 1 is a cylinder, and insert in the

square rack

2,17 places are provided with air filter screen 7 at air intake vent, be provided with a plurality of condenser pipes 8 at the rear portion of air intake vent 17, the lower end of condenser pipe 8 is provided with water-collecting tray 9, be set up in parallel fin 10 mutually with condenser pipe 8, at

air outlet

18,10 of fin set firmly fan 11, compressor 12 is equipped with in the bottom of casing 1, radiator fan 13 and fin 14, air is sent in the charging basket 3 by conduit 19 by air outlet 18, the top of charging basket 3 is equipped with conduit 16 and is connected with air intake vent 17, makes air carry out circular treatment.

Fig. 1 is the prior art structure chart of plastic blow molding machine and drying machine;

Fig. 2 is the structural plan figure of the utility model plastic moisture removing drying machine;

Fig. 3 is that the utility model plastic moisture removing drying machine is connected plane with blow moulding machine;

Seeing also Fig. 2 the utility model plastic moisture removing drying machine is by air intake vent 17, and have additional air filter screen 7 at air intake vent 17 places, in engine housing, be provided with compressor 12, compressor 12 is connected with a plurality of condenser pipes 8, below a plurality of condenser pipes 8, be provided with water-collecting tray 9, one termination of water-collecting tray 9 has overflow pipe 91, be provided with a plurality of fin 10 in the rear end of a plurality of condenser pipes 8, the fan 11 that links to each other with fin 10 is delivered to the air of drying in the charging basket 3 by air outlet 18, burn out in order to make compressor 12 be unlikely to overheated, divide into air vent 15 and air is blown on the compressor 13 through fin 14 at dehumidifying heat pump and play radiating effect by radiator fan 13.

The utility model plastic moisture removing drying machine is connected as shown in Figure 3 with plastic-injection moulding machine, the upper end of the charging basket 3 of injection molding machine is connected with conduit 16, conduit 16 is connected with the air intake vent 17 of plastic moisture removing drying device, air enters a plurality of condenser pipes 8 through airstrainer 7, make the water droplet of moisture condensation splash into water-collecting tray 9, the air of process condenser pipe 8 enters fin 10 more residual moisture content is further evaporated, blow to air outlet 18 by fan 11 again and enter conduit 19, the air of removing the moisture drying is blown in the charging basket 3 by conduit 19 again, ringing like this, improve greatly plastic injection-moulded in because the moisture content of plastic pellet exists, and influence the problem of product quality.

The inventor has reached goal of the invention of the present utility model by the improvement on the technical pattern as above, and makes injection molding machine of plastic and complete being combined as a whole of dehumidification drying device energy.
