Abstract
The utility model relates to an air curtain type biological clean working bench. The utility model comprises a working bench surface (7), a baffle plate (9), a glass moving door (5) and a flow-spreading net plate (4). The flow-spreading net plate (4) is arranged at the upper part of the working bench surface (7), and a filter (3) with high efficiency is arranged at the upper part of the flow-spreading net plate (4). The utility model is characterized in that a slit (8) is formed between the flow-spreading net plate (4) of one side of the glass moving door (5) and the box body plate (6) of the inner side of the glass moving door (5), the slit (8) is utilized to make the filter (3) with high efficiency send the airflow, and the opening mouth of the slit (8) is downward. The slit (8) can form an air curtain, so the inner airflow and the outer airflow of a working area can be prevented from being exchanged.
Description
The utility model relates to a kind of biologic cleanliness workbench.
In the prior art, the biologic cleanliness workbench is applicable to industries such as pharmacy, health care, chemical experiment, requires to provide aseptic, dustless clean environment.Existing clean bench moves the interchange of air-flow inside and outside the prevention by glass, but still has a spot of air-flow to escape the infringement staff in the workspace or outside non-clean gas flow immerses the workspace, influences the cleanliness factor in the workspace.
The purpose of this utility model is to provide a kind of air-curtain type biologic cleanliness workbench that can stop the inside and outside air-flow in workspace to immerse mutually effectively.
The technical solution of the utility model is: the glass that it comprises work top, be arranged at the baffle plate at work top upper front part and rear portion respectively, be arranged at work top top left part and right part respectively moves door, is arranged at the flow dispensing net board of work top top, the top of this flow dispensing net board is provided with high efficiency particulate air filter, the below of work top is provided with return air channel, and described return air channel is connected with the air channel at high efficiency particulate air filter place; Form the air communication that the confession high efficiency particulate air filter sends between the flow dispensing net board that described glass moves door one side and the box plate that glass moves an inboard and cross the slit that Open Side Down.
The utility model compared with prior art has following advantage:
Because the air-flow that slit produces can form air curtain, can stop the exchange of inside and outside air-flow effectively, air-flow escaped in the workbench so both can stop; the protection operating personnel; prevent that outside non-clean gas flow from immersing the workspace yet, influence the cleanliness factor in the workspace, air curtain does not influence the radial transfer of object yet.
The utility model will be further described below in conjunction with drawings and Examples:
Accompanying drawing is a structural front view of the present utility model; Wherein:
[1]. exhaust-air filter; [2]. air exhaust passage; [3]. high efficiency particulate air filter; [4]. flow dispensing net board; [5]. glass moves door; [6]. box plate; [7]. work top; [8]. slit; [9]. baffle plate; [10]. return air channel; [11]. the inclined-plane;
Embodiment: referring to accompanying drawing, the glass that the utility model comprises work top [7], be arranged at the baffle plate [9] at work top [7] upper front part and rear portion respectively, be arranged at work top [7] top left part and right part respectively moves door [5], is arranged at the flow dispensing net board [4] of work top [7] top, the top of this flow dispensing net board [4] is provided with high efficiency particulate air filter [3], the below of work top [7] is provided with return air channel [10], and described return air channel [10] is connected with the air channel at high efficiency particulate air filter [3] place; Flow dispensing net board [4] and the glass that described glass moves door [5] one sides moves and forms the air communication that supplies high efficiency particulate air filter [3] to send between the inboard box plate [6] of door [5] and cross the slit that Open Side Down [8], and this slit [8] can form vertical air curtain.Described box plate [6] extends the formation flow-stopping plate vertically upward from the opening part of slit [8]; The edge part that described glass moves the flow dispensing net board [4] of door [5] one sides forms to inclined-plane [11] the formation guide face that slit [8] tilts, and vertically extend and the common air curtain diversion outlet that constitutes vertically downward of box plate [6] bottom of this inclined-plane [11] again.The top of described high efficiency particulate air filter [3] is provided with air exhaust passage [2], is provided with exhaust-air filter [1] in this air exhaust passage [2], discharges after the wind of discharging is filtered again, and prevents that harmful mushroom of workspace from influencing environment.
