Description

Technical Field

[0001] The utility model relates to the technical field of laboratory ventilation, in particular to a laboratory purification ventilation structure. Background Art

[0002] In today's rapidly developing science and technology, as an important place for scientific research and experimental exploration, the control of laboratory environmental conditions is particularly important. Among them, the maintenance of air quality is particularly critical, which is directly related to the accuracy of experimental results and the health of researchers. However, long-term closed laboratory environment often leads to a decline in air quality. Therefore, installing effective ventilation equipment has become a necessary means to ensure laboratory air quality.

Although this method promotes air exchange to a certain extent, it has significant defects. Unfiltered air may carry particles into the laboratory and interfere with precision experiments. At the same time, harmful gases that may be generated during the experiment, if directly discharged without purification, will not only affect the experimental environment, but may also pollute the external environment.

DETAILED DESCRIPTION

[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figure 1 As shown, the utility model provides a laboratory purification ventilation structure, including a laboratory purification ventilation structure, including a box shell 10, a plurality of mounting parts are provided inside the box shell 10, and an air supply component 20 and an air outlet component 30 are provided on these mounting parts, wherein the air supply component 20 is connected in series with a first filter device 21 and a second filter device 22, and the two-stage filter device fully filters the particles carried by the outside air to avoid interference with the interior of the laboratory, and at the same time, the air outlet b31 component is provided with a third filter device 32, which can filter the harmful gases generated during the experiment to prevent them from directly flowing into the outside and polluting the environment.

[0029] like Figure 2As shown, the rear side of the box shell 10 is provided with a boss near the top side, the bottom of the boss is a first mounting portion 11, and the second mounting portion 12 and the third mounting portion 13 are respectively provided on the rear side wall and the bottom wall inside thereof, and the fourth mounting portion 14 and the fifth mounting portion 15 are provided on the front side wall of the box shell 10 through a partition, and an air outlet 17 is opened on the top of the box shell 10.

[0030] like Figure 3-4 As shown, the air supply assembly 20 includes a first filter device 21, a second filter device 22, an electrically controlled extrusion airbag 23 and a crank extrusion device 24. The first filter device 21 is arranged on the first mounting portion 11, the second filter device 22 is arranged on the second mounting portion 12, the electrically controlled extrusion airbag 23 is arranged on the third mounting portion 13, and the crank extrusion device 24 is arranged on the fourth mounting portion 14. The arc-shaped clamping plate 2404 on the crank extrusion device 24 can squeeze the electrically controlled extrusion airbag 23 to provide gas flow support for the air supply group. The tops of the first filter device 21 and the second filter device 22 are connected by a pipe, the bottom of the second filter device 22 is connected to the rear side of the electrically controlled extrusion airbag 23 by a pipe, the front side of the electrically controlled extrusion airbag 23 is connected to the air supply port 17 by a pipe, and the air supply port 17 is connected to the ventilation duct at the top of the laboratory, thereby providing clean air for the laboratory.

[0031] It should be noted that the first filter device 21 is a primary filter, which is mainly used to capture larger dust particles and is mainly made of activated carbon filter material or non-woven fabric. The second filter device 22 is a high-efficiency filter, which is used to capture small-sized suspended particles and is mainly made of ultra-fine glass fiber paper as filter material.

[0032] In this embodiment, the controller 40 is disposed on the fifth mounting portion 15 .

[0033] In this embodiment, there are two first filter devices 21, and an air inlet 2101 is provided on the rear side of each first filter device 21. Multiple air inlets 2101 and the first filter device 21 can speed up the filtering efficiency of the air. At the same time, the air after coarse filtration converges into the second filter device 22 for further filtration, thereby improving the final filtering efficiency.

[0034] like Figure 4 As shown, the fourth mounting portion 14 is formed by welding four layers of structural plates, which are structural plate one, structural plate two, structural plate three and structural plate four from top to bottom. A sleeve 1401 is provided between structural plate two and structural plate three, a connecting plate 1402 is provided on the top of structural plate four, and hinge portions 14021 are provided on the left and right sides of the connecting plate 1402.

[0035] Furthermore, the crank extrusion device 24 includes a motor 2401, which is arranged on the top of the top structural plate 1, and a piston crank connecting rod 2402 is arranged at the output shaft of the motor 2401. The piston of the piston crank connecting rod 2402 is slidingly arranged in the sleeve 1401, and the bottom of the piston crank connecting rod 2402 is symmetrically hinged with two bent clamping arms 2403. The bending part of the bent clamping arm 2403 is hinged to the hinge part 14021, and the end of the bent clamping arm 2403 is provided with an arc-shaped clamping plate 2404. When the bent clamping arm 2403 is folded, the two arc-shaped clamping plates 2404 clamp the electric-controlled extrusion device in the middle, and the motor 2401 is electrically connected to the controller 40.

[0036] Furthermore, a first solenoid valve 2301 is provided at the rear inlet of the electrically controlled extrusion airbag 23 , and a second solenoid valve 2302 is provided at the front outlet thereof. The first solenoid valve 2301 and the second solenoid valve 2302 are electrically connected to the controller 40 .

[0037] Specifically, such as Figure 6 As shown, the controller 40 controls the motor 2401 to rotate, thereby driving the piston on the piston crank connecting rod 2402 to make reciprocating motion in the vertical direction on the sleeve 1401, and then drives the bent clamping arm 2403 to rotate back and forth with the hinge part 14021 as the axis, so that the arc clamping plate 2404 clamps and releases the electric-controlled extrusion airbag 23. When it is about to be clamped, the controller 40 controls the first solenoid valve 2301 to close and the second solenoid valve 2302 to open. At this time, the electric-controlled extrusion airbag 23 is squeezed to squeeze the filtered air into the air supply port 17, thereby flowing When entering the laboratory and about to be released, the first solenoid valve 2301 is controlled to open and the second solenoid valve 2302 is closed. The electrically controlled extrusion airbag 23 generates negative pressure inside due to its own elastic recovery potential energy, and then the air at the air inlet 2101 flows through the first filter device 21 and the second filter device 22 under the influence of the pressure difference, thereby completing the filtered air reserve for the next extrusion. During the extrusion and air supply process, the power of the motor 2401 can be adjusted according to the actual situation, so as to achieve the regulation and control of the extrusion frequency of the electrically controlled extrusion airbag 23, and finally realize the regulation of the air supply volume in the laboratory.

[0038] like Figure 2 As shown, the air outlet assembly 30 includes an air outlet b31, which is arranged on the front side of the box shell 10 near the bottom side, and a third filter device 32 is arranged on the rear side of the air outlet b31. The third filter device 32 can be provided with corresponding filter materials according to the type of laboratory to eliminate harmful substances generated by the experiment and prevent them from flowing into the outside. The rear side of the third filter device 32 is provided with an air outlet duct 33, which passes through the rear side of the box shell 10 and extends outward.

[0039] like Figure 5As shown, the fifth mounting portion 15 is provided with a temperature control unit 25, and the air inlet a2501 and the air outlet a2502 are respectively provided on the left and right sides of the temperature control unit 25. The front side of the electrically controlled extrusion airbag 23 is connected with the air inlet a2501 through a pipe, and the air outlet a2502 is connected with the air supply port 17 through a pipe. The temperature control unit 25 is electrically connected to the controller 40, and the temperature of the filtered air is controlled by the temperature control unit 25, so that the staff in the laboratory can have a better experimental environment.

[0040] The temperature control unit 25 may be an air conditioner.

[0041] In this embodiment, a perspective window 16 is provided on the front side of the box shell 10 near the top. The front side of the box shell 10 is located inside the laboratory. Maintenance personnel can view the internal operation status of the device through the perspective window 16, which is convenient for preliminary troubleshooting.

[0042] The above structure solves the problem in the prior art that unfiltered air directly flows into the laboratory, causing interference with precision experiments and affecting the experimental environment. At the same time, harmful gases generated in the experiment are directly discharged outdoors, causing pollution to the external environment.

[0043] It should be noted that the specific models and specifications of the controller 40, the first solenoid valve 2301, the second solenoid valve 2302, the temperature control unit 25 and the motor 2401 need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0044] The power supply and principles of the controller 40 , the first solenoid valve 2301 , the second solenoid valve 2302 , the temperature control unit 25 and the motor 2401 are clear to those skilled in the art and will not be described in detail here.

[0045] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
