Abstract
The invention relates to a flow rectifier in a negative-pressure weighing chamber. The flow rectifier is installed between an air supplying box and a work area. The flow rectifier comprises a fixing frame. Flow rectifying plates are fixed to the fixing frame. A plurality of flow rectifying holes distributed in an arrayed mode are formed in the flow rectifying plates. At least two flow rectifying plates are arranged, a gap is formed between the flow rectifying plates, and the flow rectifying holes in the two adjacent flow rectifying plates are formed in a staggered mode. By means of the structure, the effects of reducing the air speed and rectifying flow can be achieved through the flow rectifying holes in the two flow rectifying plates, it is guaranteed that the air speed in the work area is consistent, operation is convenient, the structure is simple, and the production efficiency can be improved.
Description
Technical field
The present invention relates to a kind of equipment in biologic medical industry, especially relate to the current equalizer in a kind of negative pressure weighing room.
Background technology
In pharmaceuticals industry, the process of pharmacy is the requirement needing to meet GMP, the supplementary material weighing of preparation or the sampling of dried material or product, weigh, mixing, packaging waits operation and produces tablet, bulk drug, the workshop of oral agents etc. is in weighing, mixing, sieve, whole grain, compressing tablet, capsule-filling, the filling grade in technique process of pulvis all must meet certain purity requirements, avoid dust from flying diffusion occurring and batch mixing or cross pollution occurring, negative pressure weighing room works to meet above-mentioned requirements, and wind is directly passed into working region in the outlet of wind pushing box by existing negative pressure weighing room, the wind speed at each position of working region is caused to differ like this, thus cause work to have some setbacks, affect production efficiency.
Summary of the invention
Technical problem to be solved by this invention is to provide the current equalizer of a kind of wind speed evenly and in the negative pressure weighing room smoothly of working.
The present invention solves the technical scheme that its technical problem takes: the current equalizer in a kind of negative pressure weighing room, be installed between wind pushing box and workspace, described current equalizer comprises fixed frame, described fixed frame is fixed with homogenizing plate, described homogenizing plate is provided with some equal discharge orifices be arranged in array, described homogenizing plate at least two and there is gap centre, the equal discharge orifice on the adjacent homogenizing plate described in two is staggered.
Concrete further, described homogenizing plate is provided with the shutter for blocking equal discharge orifice, and described shutter is provided with and current-sharing hole number on homogenizing plate and air vent of the same size, and described shutter slidably.
Concrete further, described shutter is provided with tooth bar, and described fixed frame is provided with gear, described gear shaft is connected with manual adjustments knob, described wheel and rack engagement.
Concrete further, described shutter is provided with tooth bar, and described fixed frame is provided with gear, and described gear shaft is connected with drive motors, described wheel and rack engagement.
The invention has the beneficial effects as follows: after have employed said structure, can be reached the effect reducing wind speed and current-sharing by the equal discharge orifice on two homogenizing plates, ensure that in workspace, wind speed is consistent, handled easily, structure is simple, can enhance productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, fixed frame; 2, homogenizing plate; 3, equal discharge orifice; 4, shutter; 5, air vent; 6, tooth bar; 7, gear; 8, manual adjustments knob.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is explained in detail.
Current equalizer as shown in Figure 1 in a kind of negative pressure weighing room, be installed between wind pushing box and workspace, described current equalizer comprises fixed frame 1, described fixed frame 1 is fixed with homogenizing plate 2, described homogenizing plate 2 is provided with some equal discharge orifices 3 be arranged in array, described homogenizing plate 2 at least two and there is gap centre, the equal discharge orifice 3 on the adjacent homogenizing plate 2 described in two is staggered, can be uniformly distributed component and can reduce wind speed.
Homogenizing plate 2 is provided with the shutter 4 for blocking equal discharge orifice 3, described shutter 4 is provided with and equal discharge orifice 3 quantity and air vent of the same size 5 on homogenizing plate 2, described shutter 4 slidably, air quantity can be regulated as required, the structure of manual adjustments air quantity is that shutter 4 is provided with tooth bar 6, and described fixed frame 1 is provided with gear 7, described gear 7 axle is connected with manual adjustments knob 8, and described gear 7 engages with tooth bar 6; The structure of motorized adjustment air quantity is that shutter 4 is provided with tooth bar 6, and described fixed frame 1 is provided with gear 7, and described gear 7 axle is connected with drive motors, and described gear 7 engages with tooth bar 6.
Said structure is simple, easy to operate, can have the effective production efficiency improving product, ensures that wind speed is even.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
