Description
Technical field
The injection molding drier that the utility model relates to a kind of filter and comprises this filter, in particular, the injection molding drier that relates to a kind of hot air circulating filter device and comprise this filter, belongs to injection molding technology field.
Background technology
In Injection Industry, drying machine is used quite universally, the operation principle of common drying machine be by blower fan by cold wind suction, through after thermotank heating, be blown in material, the moisture in material is taken away, finally the exhaust outlet by drying box is discharged in air.When thermotank adds hot-air, electric energy and heat energy loss are large, and after Bas Discharged, dust pollution is large, not environmental protection.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, a kind of loss that reduces heat energy and electric energy is provided, reduces the hot air circulating filter device of dust pollution.
Meanwhile, the utility model also provides a kind of injection molding drier that comprises filter addressing the above problem.
In order to solve above technical problem, the utility model provides a kind of hot air circulating filter device, the filter body that comprises both ends open, described filter body inside arranges screen pack, one of them openend arranges end cap, another openend arranges grid type gas outlet, and a place, side of described filter body is provided with outwardly air inlet, is provided with pressure balance mouth on the sidewall of described air inlet.
Being further defined to of technical solutions of the utility model, the bottom of described filter body arranges dust inspection socket.
Further, the air inlet inclination miter angle of described evagination arranges.
Another technical scheme that the utility model provides is: a kind of injection molding drier that comprises above-mentioned hot air circulating filter device, comprise baking oven and motor, the air inlet of described baking oven is communicated with the air outlet of described motor by heating tube, also comprise hot air circulating filter device, the air inlet of described hot air circulating filter device is communicated with the exhaust outlet of described baking oven by pipeline, described in state the gas outlet of hot air circulating filter device and the fan blade of described motor is oppositely arranged.
Being further defined to of the technical program, the distance between the gas outlet of described hot air circulating filter device and the fan blade of described motor is less than 1m.
The beneficial effects of the utility model are: a kind of hot air circulating filter device that the utility model provides and the injection molding drier that comprises this filter, reduce the loss of heat energy, reduce the loss of electric energy, collect dust, reduce the pollution of the dust in environment, reduce the particle rubbish in environment; Use the utility model and use the environment facies ratio of common drying box, environment temperature and environment smell are greatly improved, and, by dust observation panel can directly observe heated air circulation device dust, accomplish timely cleaning, simple in structure, simple operation.
Accompanying drawing explanation
The left view of the hot air circulating filter device that Fig. 1 provides for the utility model;
The front view of the hot air circulating filter device that Fig. 2 provides for the utility model;
The structural representation of the injection molding drier that Fig. 3 provides for the utility model.
The specific embodiment
A kind of hot air circulating filter device that the present embodiment provides, as shown in Figure 1, its front view as shown in Figure 2, comprises the filter body 1 of both ends open to its left view.
Filter body 1 inside arranges screen pack 2, for filtering the dust that passes into gas.Filter body 1 opening one end arranges end cap 5, and one of them openend arranges end cap 5, and another openend arranges grid type gas outlet, and end cap 5 is for changing screen pack 2, simple operation.
One place, side of filter body 1 is provided with outwardly air inlet 4, and the air inlet 4 inclination miter angles of evagination arrange, and make the gas passing into have the maximum path that contacts with screen pack 2, improve the degree of purity filtering.On the sidewall of air inlet 4, be provided with pressure balance mouth 3, automatically regulate the pressure in filter body 1, avoid filter body 1 internal pressure to heave too greatly.
The bottom of filter body 1 arranges dust inspection socket 6, opens can observe screen pack 2 dust and have how many, whether needs cleaning.
The present embodiment also provides a kind of injection molding drier that comprises above-mentioned hot air circulating filter device, and its structural representation as shown in Figure 3, comprises baking oven 7, motor 9 and hot air circulating filter device 8.
The air inlet of baking oven 7 is communicated with the air outlet of motor 9 by heating tube 11, and the air inlet 4 of hot air circulating filter device 8 is communicated with the exhaust outlet 12 of described baking oven 7 by pipeline; State the gas outlet of hot air circulating filter device 8 and the fan blade 10 of motor 9 is oppositely arranged.Distance between the fan blade 10 of the gas outlet of hot air circulating filter device 8 and motor 9 is less than 1m.
The direction of arrow in Fig. 3 is gas communication direction, its workflow is: during motor 9 work, the air in hot air circulating filter device 8 is blown into heating tube 11, heating tube 11 will enter baking oven 7 again after air heat, the moisture of material is taken and delivered to baking oven 7 out of exhaust outlet 12, exhaust outlet 12 blows into hot air circulating filter device 8 by the air with steam and dust, so circulation.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
