Abstract
The utility model discloses an air supply unit flow channel for fan filter unit (FFU), which is simple in structure and reasonable in design and comprises a casing approximately in a rectangular structure. A square groove is arranged at the top of the casing, and a fan body is arranged in the groove. A first diverting board, a second diverting board and a third diverting board are arranged in a box body. The first diverting board is arranged at one end of the casing, the second diverting board is arranged at the other end of the casing, and the third diverting board is arranged at a middle position of the bottom of the casing. The first diverting board and the third diverting board form a first air outlet, and the second diverting board and the third diverting board form a second air outlet. An optimum air supply flow channel is formed by calculating the requirements of sound reducing and static pressure space, thereby enabling the air outlet to be even, effectively reducing noises, enabling FFU noises to be controlled at 45 decibals (dB) at the minimum, improving working efficiency, saving manufacture cost and being convenient to popularize and implement.
Description
Technical field
The utility model relates to industrial ventilation device runner, particularly a kind of FFU blowing unit runner.
Background technique
More than ten years appear having only in FFU on China market; The professional term of FFU Chinese is a blower fan filtering unit, and the design of its modular structure, easy construction are when the user needs part upgrading cleanliness; Only needing to set up the FFU unit on the top gets final product; Deal with around the need clean area and get final product, can shorten the engineering time at the scene greatly, and it is extremely low to build cleanroom's cost of formula with respect to ground.FFU lumps together the terminal cleaning equipment that formation self can provide power with blower fan and filter set, is much needing clean occasions to use.For the adaptability of technology change, FFU more has its superiority, and when technological development need improve clean rank, the quantity of taking to increase FFU just can reach the purpose that improves cleanliness, and not only making things convenient for does not influence normally carrying out of production again.
Therefore present domestic employing FFU unit is more and more, and development speed is very fast, and in the FFU performance, noise is one of its important techniques index, and the design of blowing unit runner and noise exist very big relation.Yet manufacturer is because the air channel design is rationally little and then cause FFU unit noise very big at present.If when improving the clean efficient of filter, can avoid noise again, with the performance that improves filter to a great extent.
The model utility content
The purpose of the utility model is the shortcoming that overcomes existing technology, and a kind of FFU blowing unit runner is provided, and its structure construction is practical, simple, easy to use, reasonable in design, long service life, and low cost of manufacture has reduced noise through its reasonable structural design.
For reaching above-mentioned purpose, a kind of FFU blowing unit runner that the utility model provides, the technological scheme below adopting: the utility model comprises housing; Said housing is similar to rectangular structure; Said case top is provided with square groove, is provided with the blower fan body in the said groove, is provided with first guide plate, second guide plate and the 3rd guide plate in the said casing; Said first guide plate is arranged at an end of said housing; Said second guide plate is arranged at the other end of said housing, and said the 3rd guide plate is arranged at the neutral position of said housing bottom, and said first guide plate and the 3rd guide plate form first exhaust outlet; Said second guide plate and the 3rd guide plate form second exhaust outlet.
Further, the chamfering transition is adopted in the face joint, the left and right sides of said housing top end and housing.
Further, said first guide plate and second guide plate are circular-arc.
Further, the two end part perk of said the 3rd guide plate forms flap, and the horizontal plane of said flap and guide plate forms an angle, and said angle is 30 °～45 °.
Further, said case top two ends are provided with the handgrip of one group of symmetry, are provided with control knob near the handgrip of housing one end.
The beneficial effect of the utility model is: the utility model reasonable in design; Demand through calculating noise reduction static pressure space constructs the air-supply runner an of the best with first guide plate and second guide plate between casing and said the 3rd guide plate, effectively reduced noise, makes the minimum 45dB of caning be controlled in of FFU noise; And blower fan is installed also very convenient; Effectively raise working efficiency, saved fabricating cost, be convenient to promotion and implementation.
This FFU air-supply runner simple in structure; The convenient transformation or manufacturing; Adopt the chamfering transition at the two end part of casing and the joint of sidewall; The flap of said first guide plate and curved design of second guide plate and said the 3rd guide plate also performing meritorious deeds never to be obliterated aspect the reduction noise, makes its air-out even, and air-flow is formed guiding function.
