Abstract
A variable-speed airflow control mechanism is characterized in that a dust storage and collection barrel is arranged at the upper end of a base and is connected with the base through a tube hoop; an air inlet hole is formed in the side wall of the dust storage and collection barrel; a support piece is arranged at the bottom of the dust storage and collection barrel; a first cylindrical casing adopting the structure that the upper part and the lower part are the same in diameter and a plurality of through holes are formed in the side wall is arranged at the upper end of the support piece; a second cylindrical casing adopting the structure that the upper part and the lower part are the same in diameter is arranged at the upper end of the first cylindrical casing; a filter adopting foam plastic is arranged in the first cylindrical casing; a reducing cylindrical casing is arranged at the upper end of the second cylindrical casing; a pore plate is arranged at the upper end of the reducing cylindrical casing and is connected with the reducing cylindrical casing through a tube hoop; a reducing variable-speed airflow mechanism with the upper part narrower than the lower part is arranged on the pore plate; and another pore plate is arranged on the reducing variable-speed airflow mechanism, and a reducing ventilation cavity with the upper part narrower than the lower part is arranged on the pore plate. The variable-speed airflow control mechanism has the advantage that the airflow rate can be increased, so that the working efficiency can be improved, and time can be saved.
Description
Technical field
The utility model relates to a kind of airflow control mechanism.
Background technology
At present, existing airflow control mechanism mainly comprises barrel-type casing and filtering bodies.Wherein, the two ends diameter is identical up and down for barrel-type casing, in barrel-type casing, is provided with filtering bodies.Its weak point: air velocity is balanced, at the bottom of the operating efficiency, loses time.
Summary of the invention
The purpose of the utility model provides a kind of quickening air velocity, thereby increases work efficiency, time-saving a kind of speed change airflow control mechanism.
The utility model mainly includes base, pipe collar, storage dust bucket, filter assemblies, air-flow gear and ventilation body cavity.Wherein, be provided with the storage dust bucket in the base upper end, base preferably links to each other through ring with the storage dust bucket.On storage dust bucket sidewall, be provided with air admission hole, support member places above-mentioned storage dust bucket bottom, and the support member upper end is provided with the barrel-type casing that has some through holes on the identical and sidewall of diameter up and down.Be provided with the identical barrel-type casing of diameter about in the of in this barrel-type casing upper end, in barrel-type casing, be provided with filtering bodies, its filtering bodies can be foamed plastics, pottery grain and activated carbon or the like.Be provided with a reducing barrel-type casing in this barrel-type casing upper end, be provided with an orifice plate in this reducing barrel-type casing upper end, orifice plate preferably links to each other through ring with above-mentioned reducing barrel-type casing.On this orifice plate, be provided with up-narrow and down-wide reducing speed change airflow mechanism, this mechanism's reducing speed change airflow mechanism is provided with an orifice plate, and this orifice plate is provided with up-narrow and down-wide reducing ventilation body cavity.
The utility model in use, gas enters into the storage dust bucket from air admission hole, gas rises and to pass the gentle rheology speed of filter assemblies mechanism successively, overflows from the ventilation body cavity at last.
The utility model compared with prior art has following advantage: accelerate air velocity, thereby increase work efficiency, save time.
Description of drawings
Fig. 1 is the three-dimensional simplified schematic diagram of the utility model.
The specific embodimentIn the simplified schematic diagram of a kind of speed change airflow control mechanism shown in Figure 1, be provided with storage dust bucket 2 in base 1 upper end, base preferably links to each other through ring 3 with the storage dust bucket.On storage dust bucket sidewall, be provided with air admission hole, support member 4 places above-mentioned storage dust bucket bottom, and the support member upper end is provided with the barrel-type casing 5 that has some through holes on the identical and sidewall of diameter up and down.Be provided with the barrel-type casing 6 that diameter is identical about in the of in this barrel-type casing upper end, in barrel-type casing, be provided with filtering bodies, its filtering bodies can be foamed plastics, pottery grain and activated carbon or the like.Be provided with a reducing barrel-type casing 7 in this barrel-type casing upper end, be provided with an orifice plate 8 in this reducing barrel-type casing upper end, orifice plate preferably links to each other through ring with above-mentioned reducing barrel-type casing.On this orifice plate, be provided with up-narrow and down-wide reducing speed change airflow mechanism 9, this mechanism's reducing speed change airflow mechanism is provided with an orifice plate, and this orifice plate is provided with up-narrow and down-wide reducing ventilation body cavity.
