Problems solved by technology

[0005] However, this kind of purification workbench will inevitably have a small amount of gas leaking from the high-pressure area. When there is high-risk toxic gas, the purification workbench becomes less safe and reliable

Embodiment 1

[0030] Such as figure 1 As described, the purification workbench of this embodiment includes a working chamber 2, an air intake system and an exhaust system. The air intake system includes an air intake chamber 4 located at the rear of the working chamber 2. A diffuser plate 3 is arranged at the connection; the exhaust system includes an exhaust chamber 5 located below the working chamber 2, and the rear side of the exhaust chamber 5 is connected to the air pump 8 through the exhaust port 6; the front end of the working chamber 2 A partitioned low-pressure chamber 1 is provided, and the partitioned low-pressure chamber 1 has an operation channel 9 for the operator to reach into the interior of the working chamber 2. The two sides of the partitioned low-pressure chamber are respectively an outer partition 11 and an inner partition 10, and the outer partition 11 and The inner partition 10 is provided with operation holes, and the operation channel is formed between the operation...

Embodiment 2

[0033] Such as figure 2 As shown, this embodiment is an improvement on the basis of Embodiment 1, and the main structures of the two are the same. The specific improvement of this embodiment lies in:

[0034] The upper part of the operation channel 9 is provided with a stopper 7, the side of the stopper close to the 7 working cavity 2 is provided with a first drainage surface (inner concave surface) facing the inside of the working cavity, and the side of the stopper 2 close to the operator (far away from the working One side of the cavity) is provided with a second drainage surface (concave curved surface) facing the operator (back to the working cavity). The first and second drainage surfaces meet at the lowest point of the block 2, presenting an inverted V shape. The gas in the working chamber 2 and the outside atmosphere form a downward flow trend under the drainage action of the first and second drainage surfaces respectively. Wherein, the lowest point of the block 7 i...

Abstract

The invention relates to a horizontal laminar flow clean work station. The clean work station includes a work chamber, a gas inlet system and a gas discharge system. The gas inlet system includes a gas inlet chamber located at the rear part of the work chamber. The gas discharge system includes a gas discharge chamber located below the work chamber. A gas discharge outlet is arranged on the rear side of the gas discharge chamber. A separated low-pressure chamber is formed on the front end of the work chamber and is provided with an operation channel allowing an operator to put hands into the work chamber. The bottom of the separated low-pressure chamber is communicated with the gas discharge chamber. In the clean work station, the separated low-pressure chamber is formed at the operation channel to form negative pressure in the separated low-pressure chamber, thereby pumping the gas flowing out from the operation channel. By means of the negative pressure in the low-pressure chamber, gas in the work chamber and external atmosphere are sucked into the operation channel, thereby preventing internal gas from leaking through the operation channel and external gas from entering the working zone. The two gas flows are mixed in the operation channel and are rapidly removed, so that internal gas in the work chamber is effectively prevented from leaking.

Description

technical field [0001] The invention relates to a horizontal laminar flow purification workbench. Background technique [0002] In industrial production and scientific research, dust-free working environment is required in many places. The purification workbench can provide an effective working environment for these purposes and improve the efficiency of production and scientific research. However, there are some defects in the currently used workbench. Generally speaking, the clean workbench area maintains a positive pressure on the atmosphere, so that there are volatile substances in the work process that will be directly discharged to the body of the operator. This seriously affects the health of the operating personnel. At the same time, during the operation, when the hands and other parts of the operator enter the clean work area, a large amount of dust particles will also be brought in, which will affect the cleanliness of the clean work area. [0003] The applicant...
