Description

Technical Field

[0001] This application relates to the field of radiation protection technology, and in particular to a ventilation device for a pollution prevention workstation. Background Technology

[0002] Traditional radiation protection workstations primarily focus on the radiation protection wall structure and radiation shielding materials, but they do not adequately consider the air quality and ventilation system within the workstation. With increasing demands for working environments, staff working long hours in radiation protection workstations not only need radiation protection but also require guaranteed indoor air quality.

[0003] Existing radiation protection workstations often have a single fresh air fan installed at the top of the workstation for ventilation. However, the air inlet of the fresh air fan is exposed to the external environment for a long time, which can easily accumulate dust and pollutants, affecting the quality of the incoming air and increasing the burden on the filter, thus shortening its service life. Summary of the Invention

[0004] This application aims to at least partially address one of the aforementioned technical problems in the prior art. To this end, embodiments of this application provide a pollution-proof workstation ventilation device that prevents the air inlet from being exposed to the external environment for extended periods, reduces the accumulation of dust and pollutants, improves air intake quality, and reduces the burden on the filtration device.

[0005] A pollution prevention workstation ventilation device, comprising:

[0006] Box;

[0007] A fan is installed in the housing, with the fan's air inlet exposed on the first end face of the housing and the fan's air outlet exposed on the second end face of the housing.

[0008] A lifting drive device is installed inside the housing, and the lifting movable end of the lifting drive device extends from the first end face of the housing;

[0009] A lifting end plate, which is larger than the air inlet of the fan, is connected to the lifting movable end of the lifting drive device, and is parallel to the air inlet of the fan.

[0010] A filter device is installed at the air outlet of the fan and connected to the housing.

[0011] In an optional or preferred embodiment, the lifting drive device is located at the four corners of the housing.

[0012] In an optional or preferred embodiment, a grille, an annular plate, and filter cotton are provided at the air inlet of the fan. The grille is installed on the housing, the annular plate is fitted over the air inlet of the fan, and the filter cotton is disposed between the grille and the annular plate.

[0013] In an optional or preferred embodiment, the filtration device includes a filter screen and a mounting base, the filter screen being assembled in the mounting base, the mounting base being connected to the housing, and the mounting base having an opening for air outlet.

[0014] In an optional or preferred embodiment, the mounting base is detachably connected to the housing.

[0015] In an optional or preferred embodiment, the fan is fixed inside the housing by a mounting plate, and the mounting plate is provided with clearance holes corresponding to the air outlet of the fan.

[0016] In an optional or preferred embodiment, a fixing plate is provided on the outer wall of the box.

[0017] In an optional or preferred embodiment, alignment right-angle plates are provided at the four corners of the bottom of the box.

[0018] Based on the above technical solution, the embodiments of this application have at least the following beneficial effects: When ventilation is required in the radiation protection workstation, the lifting drive device drives the lifting end plate to rise and open the air inlet of the fan. The fan then operates to deliver outside air into the workstation. When ventilation is not required, the lifting drive device drives the lifting end plate to fall, causing the lifting end plate to press against the air inlet of the fan, thereby closing the air inlet. This ventilation device uses a lifting end plate to control the opening and closing of the fan air inlet. The air inlet is only opened when ventilation is needed, and is blocked by the lifting end plate at other times. This avoids the air inlet from being exposed to the external environment for a long time, which can easily lead to the accumulation of dust and pollutants, thereby improving the air intake quality and reducing the burden on the filtration device.

[0030] Traditional radiation protection workstations primarily focus on the radiation protection wall structure and radiation shielding materials, but they do not adequately consider the air quality and ventilation system within the workstation. With increasing demands for working environments, staff working long hours in radiation protection workstations not only need radiation protection but also require guaranteed indoor air quality.

[0031] Existing radiation protection workstations often have a single fresh air fan installed at the top of the workstation for ventilation. However, the air inlet of the fresh air fan is exposed to the external environment for a long time, which can easily accumulate dust and pollutants, affecting the quality of the incoming air and increasing the burden on the filter, thus shortening its service life.

[0032] Reference Figures 1 to 5 This application provides a pollution prevention workstation ventilation device, including a housing 100, a fan 200, a lifting drive device 300, a lifting end plate 400, and a filter device 500.

[0033] A fan 200 is installed in a housing 100. The air inlet of the fan 200 is exposed on the first end face 110 of the housing 100, and the air outlet is exposed on the second end face 120 of the housing 100. A lifting drive device 300 is installed inside the housing 100. The lifting movable end of the lifting drive device 300 extends from the first end face 110 of the housing 100. The lifting end plate 400 is larger than the air inlet of the fan 200. The lifting end plate 400 is connected to the lifting movable end of the lifting drive device 300. The lifting end plate 400 is parallel to the air inlet of the fan 200. A filter device 500 is installed at the air outlet of the fan 200 and connected to the housing 100.

[0034] When ventilation is needed in the radiation protection workstation, the lifting drive device 300 drives the lifting end plate 400 to rise, opening the air inlet of the fan 200. The fan 200 then draws outside air into the workstation. When ventilation is not needed, the lifting drive device 300 drives the lifting end plate 400 to fall, pressing it against the air inlet of the fan 200 and closing it. This ventilation device uses the lifting end plate 400 to control the opening and closing of the fan 200's air inlet. The air inlet is only opened when ventilation is needed; otherwise, it is blocked by the lifting end plate 400. This prevents the air inlet from being exposed to the external environment for extended periods, reduces the accumulation of dust and pollutants, improves air quality, and reduces the burden on the filter device 500.

[0035] In this application, the housing 100 has a rectangular structure, the fan 200 is installed inside the housing 100, and a through hole is opened in the middle of the top of the housing 100. After the fan 200 is installed inside the housing 100, the air inlet of the fan 200 corresponds to the through hole at the top of the housing 100, and the air inlet is flush with the top surface of the housing 100.

[0036] The size of the lifting end plate 400 is the same as the size of the first end face 110 on the top of the box 100, and the lifting end plate 400 and the first end face 110 of the box 100 are parallel to each other.

[0037] In some embodiments, the lifting drive devices 300 are located at the four corners of the housing 100. This makes the lifting of the lifting end plate 400 more stable by synchronously driving the four lifting drive devices 300.

[0038] In this application, the lifting drive device 300 is a drive electric cylinder.

[0039] To improve the cleanliness of the incoming air, in some embodiments, a grille 600, an annular plate 700, and filter cotton (not shown in the figure) are provided at the air inlet of the fan 200. The grille 600 is installed on the housing 100, the annular plate 700 is fitted at the air inlet of the fan 200, and the filter cotton is disposed between the grille 600 and the annular plate 700.

[0040] Specifically, the grille plate 600 is installed at the through hole on the outer side of the top of the housing 100, and the annular plate 700 is installed at the through hole on the inner side of the top of the housing 100 and fitted onto the air inlet of the fan 200. The filter cotton is clamped between the grille plate 600 and the annular plate 700, thereby fixing the filter cotton at the through hole on the top of the housing 100. When the fan 200 is working, the filter cotton will filter the incoming air.

[0041] In some embodiments, the filter device 500 includes a filter screen 510 and a mounting base 520. The filter screen 510 is assembled in the mounting base 520, which is connected to the housing 100. The mounting base 520 is provided with an opening 521 for air outlet.

[0042] The mounting base 520 has a rectangular box-shaped structure. The filter screen 510 is installed inside the mounting base 520. The middle of the mounting base 520 is provided with a rectangular opening 521 for air outlet. The air discharged from the air outlet of the fan 200 is filtered by the filter screen 510 and flows out through the opening 521 on the mounting base 520 into the radiation protection workstation.

[0043] In some embodiments, the mounting base 520 is detachably connected to the housing 100. This facilitates the replacement of the filter 510.

[0044] In this application, the mounting base 520 is provided with pull buckles on its four side walls, and the housing 100 is provided with pull rings corresponding to the pull buckles on its four side walls. The pull buckles and pull rings cooperate with each other to connect the mounting base 520 and the housing 100.

[0045] In some embodiments, alignment right-angle plates 130 are provided at the four corners of the bottom of the housing 100. When it is necessary to mate the mounting base 520 with the housing 100, the four corners of the mounting base 520 are respectively aligned with the four alignment right-angle plates 130 at the bottom of the housing 100 to achieve accurate alignment between the mounting base 520 and the housing 100, facilitating quick connection between the housing 100 and the mounting base 520.

[0046] In some embodiments, the fan 200 is fixed inside the housing 100 by a mounting plate 800, and the mounting plate 800 is provided with a clearance hole 810 corresponding to the air outlet of the fan 200.

[0047] In some embodiments, a fixing plate 140 is provided on the outer wall of the housing 100.

[0048] Specifically, the enclosure 100 is provided with two rectangular fixing plates that surround the outer wall of the enclosure 100, and the enclosure 100 is installed on the top of the radiation protection workstation through the fixing plates.
