Description
Technical Field
The invention belongs to the technical field of ventilation systems, and particularly relates to a high-efficiency ventilation cabinet.
Background
The ventilation system fume hood is used for removing harmful gases, aerosols and the like generated by experimental analysis operation and preventing the harmful gases, aerosols and the like from diffusing to the surrounding. The common fume hood commonly adopted in the prior art eliminates harmful gases, aerosols and the like through a fixed exhaust outlet on the top of the hood, and does not have the function of accurately positioning and exhausting. When the ventilation system is applied to a common cabinet, the following 3 disadvantages exist: (1) during experimental analysis operation, the fume chamber glass door can not be used according to design requirements usually and is opened completely, so that the design wind speed becomes smaller and the exhaust effect is poor. (2) In a ventilation system, a common ventilation cabinet generally has a high gear and a low gear, and operators usually adopt high-grade exhaust to increase the exhaust air quantity of local points so as to ensure the ventilation effect, and the air quantity of the whole ventilation system may be insufficient. Meanwhile, when the opening area of the glass door is fixed, the air quantity is too large, the air speed is correspondingly increased, and air inlet can generate vortex at the inner plate of the ventilating cabinet, so that the actual ventilating effect is affected. (3) Personnel are in operation analysis, give off harmful substance point location indefinite, but the air exit of fume chamber is fixed, and exhaust efficiency is lower.
Disclosure of Invention
The invention aims to provide a high-efficiency ventilating cabinet, which overcomes the defects of a common ventilating cabinet, is provided with a randomly positioned gas collecting hood, and can perform the function of accurately positioning and exhausting air.
In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:
the high-efficiency ventilation cabinet is characterized in that the upper end of a metal universal shaping soft air pipe is connected with an air outlet of the ventilation cabinet, the lower end of the metal universal shaping soft air pipe is connected with a gas collecting hood, and the gas collecting hood is provided with an adjusting valve.
The upper end of the metal universal shaping soft air pipe is connected with an air outlet of the ventilating cabinet through a flange.
A rubber pad is arranged between the flanges.
The rubber pad is of a common type.
The rubber pad is made of anti-corrosion rubber.
The length of the metal universal shaping soft air pipe meets the requirement of being capable of moving to the farthest position inside the fume hood.
The gas-collecting channel is displaced and fixed with the discharge point.
And the air quantity is regulated through the regulating valve, the air speed is controlled, and high-efficiency fixed-point air exhaust is realized.
The beneficial effects obtained by the invention are as follows:
the ventilating cabinet is provided with a ventilating hood which can fix the gas collecting hood according to the point position requirement and exhaust air efficiently. The gas collecting hood capable of being randomly positioned is added, and the function of accurately positioning and exhausting air can be performed.

FIG. 1 is a block diagram of a high efficiency fume hood;
in the figure: 1-a metal universal shaping soft air pipe; 2-a regulating valve; 3-a flange; 4-a gas collecting hood; 5-a fume hood.
Detailed Description
The invention will now be described in detail with reference to the drawings and specific examples.
As shown in fig. 1, the present invention includes: the metal universal shaping soft air pipe 1, the regulating valve 2, the flange 3 and the phi 400 gas collecting hood 4. In the invention, the parts 1, 2, 3 and 4 are different from key parts of a common fume hood: the novel metal universal shaping soft air pipe 1, the regulating valve 2, the flange 3 and the phi 400 gas-collecting hood 4 are added, the metal universal shaping soft air pipe is connected with an air outlet of the ventilating cabinet through the flange, the tail end of the metal universal shaping soft air pipe is connected with the phi 400 gas-collecting hood, and the air quantity is controlled through the regulating valve. The gas-collecting hood 4 is provided with a regulating valve 2.
The upper end of the metal universal shaping soft air pipe 1 is connected with an air outlet of the ventilating cabinet, the ventilating cabinet is fixedly connected by flanges 3, rubber pads are arranged between the flanges, and the rubber pads can be of a common type or an anti-corrosion type according to the property of the discharged medium so as to prevent air leakage. The length of the metal universal shaping soft air pipe 1 is required to meet the requirement of being capable of moving to the furthest position inside the fume hood. The lower end of the metal universal shaping soft air pipe 1 is connected with a phi 400 gas collecting hood 4, can shift and fix along with a discharge point, and is used for adjusting air quantity through an adjusting valve 2, controlling air speed and realizing high-efficiency fixed-point exhaust.
The invention discloses a high-efficiency fume hood capable of randomly positioning a gas collecting hood along with a point position, which can be applied to any ventilation system, and a metal universal shaping soft air pipe, a regulating valve and a phi 400 gas collecting hood are added on the basis of a common fume hood, so that the high-efficiency fume hood has the functions of adjustability, accurate positioning and high efficiency exhaust.
