Description

Technical Field

[0001] The present application relates to the technical field of ventilation equipment, and in particular to a ventilation equipment for a dialysis room that is energy-saving and environmentally friendly. Background Art

[0002] The ventilation equipment for energy-saving and environmentally friendly dialysis rooms, namely, a ventilation fan box, has a specific structure including a box installed in a ventilation duct, a centrifugal fan installed inside the box, air inlets and air outlets are respectively provided at both ends of the box, the output end of the centrifugal fan is connected to the air outlet, a primary purification filter plate group and a high-purification filter plate group are provided inside the box near the air inlet along the length direction of the box, and three opening and closing doors corresponding to the centrifugal fan, the primary purification filter plate group and the high-purification filter plate group are respectively installed on the sides of the box.

[0003] It is mainly used in laboratories, dialysis rooms and other indoor places with high requirements on air conditions. By starting the centrifugal fan, the external air is purified by the primary purification filter plate group and the high purification filter plate group, and then discharged from the inside of the chassis through the output end of the centrifugal fan. The discharged air flows into the room through the ventilation duct, so that the room always maintains clean and fresh air.

[0004] However, after the primary purification filter plate group and the high purification filter plate group have been used for a period of time, the impurities filtered by the primary purification filter plate group and the high purification filter plate group block the filter holes of the primary purification filter plate group and the high purification filter plate group, resulting in the need to replace the primary purification filter plate group and the high purification filter plate group. However, although the ventilation fan box in the prior art is provided with an opening and closing door on the side to replace the primary purification filter plate group and the high purification filter plate group, the staff still needs to open the opening and closing door to remove the primary purification filter plate group and the high purification filter plate group from the box, and then install new primary purification filter plate group and high purification filter plate group. Since there are patients in the dialysis room, when the staff replaces the primary purification filter plate group and the high purification filter plate group, the air drawn into the room by the centrifugal fan is unpurified, which may affect the patients in the dialysis room during the dialysis process. If the staff waits for the patient's dialysis to be completed before replacing the plate group, the filter holes of the primary purification filter plate group and the high purification filter plate group are blocked, and the air drawn into the room by the centrifugal fan during the waiting process will also be unpurified. Therefore, an energy-saving and environmentally friendly ventilation equipment for dialysis rooms is needed. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide an energy-saving and environmentally friendly ventilation device for dialysis rooms, which is used to solve the technical problem in the prior art that the replacement time of the primary purification filter plate group and the high purification filter plate group is long.

[0006] The above-mentioned purpose of the present application is achieved through the following technical solutions: a ventilation device for an energy-saving and environmentally friendly dialysis room, comprising a chassis, a centrifugal fan installed inside the chassis, an air inlet and an air outlet are respectively provided at both ends of the chassis, and the output end of the centrifugal fan is connected to the air outlet. The bottom surface of the chassis near the air inlet is provided with two through-holes that pass through to the top of the chassis, and installation boxes are inserted in the two through-holes, and the two installation boxes are respectively installed with a preliminary purification filter plate group and a high purification filter plate group, and the installation box is provided with mutually connected ventilating holes on both sides relative to the air inlet and the air outlet. A spare box is installed on the upper surface of the chassis near the air inlet, and the bottom surface of the spare box is connected to the chassis, and two replacement boxes are provided in the spare box, and the structural shape of the replacement box is the same as that of the installation box, and the bottom surface of the replacement box and the upper surface of the installation box are provided with connectors for connecting the replacement box and the installation box together, and the two replacement boxes are respectively provided with a preliminary purification filter plate group and a high purification filter plate group, and protective components for preventing the installation box from falling are provided on both sides of the through-hole on the bottom surface of the chassis.

[0007] Furthermore, the upper surface and the bottom surface of the installation box are square, and the connecting piece includes a 7-shaped connecting strip and a vertical plate opposite to the transverse end face of the 7-shaped connecting strip, and the vertical plate is threaded with a connecting stud, and the connecting stud passes through the vertical plate and is threadedly connected to the transverse end face of the 7-shaped connecting strip. The connecting piece on the installation box and the connecting piece on the replacement box are interlocked with each other, the connecting piece on the installation box is horizontally arranged, and the connecting piece on the replacement box is vertically arranged.

[0008] Furthermore, the protection assembly includes protection plates rotatably connected to both sides of the through opening on the bottom surface of the chassis, and the bottom surface of the installation box abuts against the protection plates.

[0009] By adopting the above technical solution, when installing the ventilation equipment, a hole is reserved on the ceiling for the spare box to pass through, and then the chassis is installed in the ventilation duct, so that the spare box passes through the ceiling to the upper layer and the gap is filled. When the primary purification filter plate group and the high purification filter plate group need to be replaced, the protective plate is rotated so that the bottom surface of the installation box no longer abuts the protective plate, and the installation box is supported to fall. During the falling process, the installation box pulls the replacement box to fall into the chassis through the connecting piece. When the bottom surface of the replacement box moves to be flush with the bottom surface of the chassis, the protective plate is rotated again so that the bottom surface of the replacement box is flush with the bottom surface of the chassis. The surface of the replacement box is abutted against the replacement box, and then the connecting studs are twisted in the direction away from the 7-shaped connecting strip to make the connecting studs disengage from the 7-shaped connecting strip, so that the connecting parts of the replacement box can be disengaged from the connecting parts of the installation box, thus completing the replacement of the primary purification filter plate group and the high-purification filter plate group. During the replacement process, the primary purification filter plate group and the high-purification filter plate group in the replacement box purify the air, so that unpurified air hardly flows into the room during the replacement process, making the replacement time of the primary purification filter plate group and the high-purification filter plate group shorter and more convenient.

[0010] Furthermore, both upper and lower surfaces of the bottom surface of the replacement box and both upper and lower surfaces of the bottom surface of the installation box are fixedly provided with connecting pieces.

[0011] By adopting the above technical scheme, after the staff removes the installation box from the replacement box and replaces the primary purification filter plate group and the high-purification filter plate group in the installation box, they can place the installation box in the spare box, and then buckle the connecting parts on the bottom of the installation box and the connecting parts on the upper surface of the replacement box together, so that the installation box and the replacement box can be reused. Each time the primary purification filter plate group and the high-purification filter plate group are replaced, the use of the installation box and the replacement box is explained, which saves the use cost, and the connecting parts can also be used as handles, making it more convenient for the staff to pull the installation box or the replacement box.

[0012] Furthermore, an opening penetrating to the interior of the standby box is provided on one side of the standby box, and a baffle blocking the opening is inserted on the upper surface of the standby box.

[0013] By adopting the above technical solution, the baffle is pulled upward to expose the interior of the spare box, so that the staff can easily install the replacement box and the installation box in the spare box.

[0014] Furthermore, the installation box is provided with interconnected ventilating holes around it, the replacement box is provided with interconnected ventilating holes around it, and the installation box and the replacement box are provided with a plurality of installation slots for installing primary purification filter plate groups and high purification filter plate groups.

[0015] By adopting the above technical scheme, although the setting of the installation box and the replacement box makes it more convenient for the staff to replace the primary purification filter plate group and the high purification filter plate group in the chassis, for the replacement of the primary purification filter plate group and the high purification filter plate group in the installation box and the replacement box, it is necessary to make the active surface of the primary purification filter plate group and the high purification filter plate group face the air inlet, which results in that when the staff installs the primary purification filter plate group and the high purification filter plate group in the installation box and the replacement box, they need to place the components of the primary purification filter plate group and the high purification filter plate group one by one in the installation box, which is very troublesome. The setting of the ventilation holes interconnected at the periphery solves this technical problem, so that the staff can insert multiple components of the primary purification filter plate group and the high purification filter plate group from one side of the installation groove, making it more convenient for the staff to replace the primary purification filter plate group and the high purification filter plate group in the installation box and the replacement box, and also allows the staff to clearly observe whether the installation status of the primary purification filter plate group and the high purification filter plate group in the installation box and the replacement box is skewed or the installation position is incorrect.

[0016] Furthermore, an elastic rubber is fixedly provided on the inner side of the spare box along the opening shape of the spare box.

[0017] By adopting the above technical solution, when the baffle is pushed to block the opening of the spare box, the baffle will compress the elastic rubber, so that the elastic rubber fills the gap between the baffle and the spare box, thereby improving the sealing performance of the spare box.

[0018] Furthermore, a partition plate is fixedly provided inside the spare box, and the partition plate divides the inside of the spare box into two placement spaces. The two placement spaces correspond to the two openings of the chassis respectively, and the two placement spaces are both provided with a bearing assembly for bearing the replacement box.

[0019] Furthermore, the supporting assembly includes a supporting plate rotatably connected to the left and right sides of the placement space and a plurality of supporting bending springs arranged on the bottom surface of the supporting plate, one end of the supporting bending spring is fixedly connected to the bottom surface of the supporting plate, and the other end is fixedly connected to the inner wall of the placement space, and the upper surface of the supporting plate abuts the bottom surface of the replacement box.

[0020] By adopting the above technical scheme, although the setting of the protective component makes it very convenient for the staff to replace the primary purification filter plate group and the high purification filter plate group, when the staff rotates all the two protective plates to a state where they do not abut the bottom surface of the installation box, the staff may not pay attention, resulting in the installation box losing the restriction of the protective plates and falling directly. The setting of the bearing component solves this technical problem. When the staff rotates all the two protective plates to a state where they do not abut the bottom surface of the installation box, the supporting bending spring supports the replacement box against the bearing plate to prevent the installation box from falling with the replacement box, and the supported replacement box will also pull the installation box to prevent the installation box from falling. At this time, after the staff stabilizes the installation box, they pull the installation box downward so that the bottom surface of the replacement box presses the bearing plate to rotate and compress the supporting bending spring, so that the replacement box can fall into the chassis, and then the two protective plates are rotated to abut the bottom surface of the replacement box, to complete the replacement of the primary purification filter plate group and the high purification filter plate, making it safer for the staff to replace the primary purification filter plate group and the high purification filter plate.

[0021] Furthermore, two opposite limit blocks are provided at the front and rear ends of the bearing plate, and the distance between the two limit blocks is equal to the width of the opening of the chassis.

[0022] By adopting the above technical solution, the replacement box is located inside the chassis. When the staff needs to reuse the installation box, they place the installation box on the carrier plate so that it is located between the two limit blocks and the installation box is aligned with the opening of the chassis.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting the installation box, spare box, replacement box and connecting parts, it is achieved that when the initial purification filter plate group and the high purification filter plate group need to be replaced, the protective plate is rotated so that the bottom surface of the installation box no longer abuts the protective plate, and the installation box is supported to fall. During the falling process, the installation box is pulled by the connecting parts to fall into the chassis. When the bottom surface of the replacement box moves to be flush with the bottom surface of the chassis, the protective plate is rotated again to make the bottom surface of the replacement box abut against the replacement box, and then the connecting studs are twisted in the direction away from the 7-shaped connecting strip to make the connecting studs disengage from the 7-shaped connecting strip, so that the connecting parts of the replacement box can be disengaged from the connecting parts of the installation box, thus completing the replacement of the initial purification filter plate group and the high purification filter plate group. During the replacement process, the initial purification filter plate group and the high purification filter plate group in the replacement box purify the air, so that the unpurified air hardly flows into the room during the replacement process, which shortens the replacement time of the initial purification filter plate group and the high purification filter plate group and makes the replacement more convenient.

[0025] 2. By setting up the vents that are interconnected, it is possible for the staff to insert multiple components of the primary purification filter plate group and the high-purification filter plate group from one side of the installation slot, making it more convenient for the staff to replace the primary purification filter plate group and the high-purification filter plate group in the installation box and the replacement box, and also allowing the staff to clearly observe whether the installation status of the primary purification filter plate group and the high-purification filter plate group in the installation box and the replacement box is skewed or the installation position is incorrect.

[0026] 3. Through the setting of the bearing assembly, when the two protective plates of the staff are all rotated to a state where they do not abut the bottom surface of the installation box, the supporting bending springs will support the replacement box against the bearing plates to prevent the installation box from falling with the replacement box, and the supported replacement box will also pull the installation box to prevent the installation box from falling. At this time, after the staff has stabilized the installation box, they will pull the installation box downward to make the bottom surface of the replacement box press the bearing plate to rotate and compress the supporting bending springs, so that the replacement box can fall into the chassis, and then the two protective plates are rotated to abut the bottom surface of the replacement box to complete the replacement of the primary purification filter plate group and the high purification filter plate, making it safer for the staff to replace the primary purification filter plate group and the high purification filter plate.

DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with the accompanying drawings.

[0035] Example, see Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5, a ventilation device for an energy-saving and environmentally friendly dialysis room, comprising a chassis 1, a centrifugal fan (not shown in the figure) installed inside the chassis 1, an air inlet and an air outlet are respectively provided at both ends of the chassis 1, the output end of the centrifugal fan is connected to the air outlet, and the bottom surface of the chassis 1 near the air inlet end is provided with two through-holes that penetrate to the top of the chassis 1, and installation boxes 2 are plugged into the two through-holes, and the two installation boxes 2 are respectively installed with a primary purification filter plate group and a high purification filter plate group, and the installation boxes 2 are provided with mutually connected ventilating holes 20 on both sides relative to the air inlet and the air outlet, and a spare box 3 is installed on the upper surface of the chassis 1 near the air inlet end, and the bottom surface of the spare box 3 is connected to the chassis 1, and two replacement boxes 30 are provided in the spare box 3, and the replacement box 30 The structural shape is the same as that of the installation box 2, and a connector 4 for connecting the replacement box 30 and the installation box 2 is provided on the bottom surface of the replacement box 30 and the upper surface of the installation box 2. The two replacement boxes 30 are respectively provided with a primary purification filter plate group and a high purification filter plate group. Both sides of the opening on the bottom surface of the chassis 1 are provided with protective components to prevent the installation box 2 from falling. The upper surface and bottom surface of the installation box 2 are square. The connector 4 includes a 7-shaped connecting strip 40 and a vertical plate 41 opposite to the transverse end surface of the 7-shaped connecting strip 40. The vertical plate 41 is threadedly connected with a connecting stud 42. The connecting stud 42 passes through the vertical plate 41 and is threadedly connected to the transverse end surface of the 7-shaped connecting strip 40. The connector 4 on the installation box 2 and the connecting stud on the replacement box 30 The parts 4 are buckled with each other, the connecting parts 4 on the installation box 2 are arranged horizontally, and the connecting parts 4 on the replacement box 30 are arranged vertically. The protective assembly includes protective plates 5 that are rotatably connected to both sides of the opening on the bottom surface of the chassis 1. The bottom surface of the installation box 2 abuts the protective plates 5. When installing the ventilation equipment, a through hole for the spare box 3 to pass through is reserved on the ceiling, and then the chassis 1 is installed in the ventilation duct, so that the spare box 3 passes through the ceiling to the upper layer and fills the gap. When the primary purification filter plate group and the high purification filter plate group need to be replaced, the protective plates 5 are rotated so that the bottom surface of the installation box 2 no longer abuts the protective plates 5, and the installation box 2 is supported to fall. During the falling process, the installation box 2 pulls the replacement box 30 to fall into the chassis 1 through the connecting parts 4. When the replacement When the bottom surface of the box 30 moves to be flush with the bottom surface of the chassis 1, the protective plate 5 is rotated again to make the bottom surface of the replacement box 30 abut against the replacement box 30, and then the connecting studs 42 are twisted in the direction away from the 7-shaped connecting strip 40 to make the connecting studs 42 disengage from the 7-shaped connecting strip, so that the connecting piece 4 of the replacement box 30 can be disengaged from the connecting piece 4 of the installation box 2, thereby completing the replacement of the primary purification filter plate group and the high purification filter plate group. During the replacement process, the primary purification filter plate group and the high purification filter plate group in the replacement box 30 purify the air, so that the unpurified air hardly flows into the room during the replacement process, which shortens the replacement time of the primary purification filter plate group and the high purification filter plate group and makes the replacement more convenient.

[0036] Although the arrangement of the installation box 2 and the replacement box 30 makes it more convenient for the staff to replace the primary purification filter plate group and the high purification filter plate group in the chassis 1, for the installation box 2 and the replacement box 30, the active surfaces of the primary purification filter plate group and the high purification filter plate group need to face the air inlet. This results in that when the staff installs the installation box 2 and the primary purification filter plate group and the high purification filter plate group in the replacement box 30, they need to place the components of the primary purification filter plate group and the high purification filter plate group one by one in the installation box 2, which is very troublesome. In order to solve this technical problem, the present embodiment has mutually opened holes around the installation box 2. Interconnected vents 20 are provided around the replacement box 30, and multiple mounting grooves 6 for mounting primary purification filter plate groups and high purification filter plate groups are provided in the installation box 2 and the replacement box 30, so that the staff can insert multiple components of the primary purification filter plate groups and the high purification filter plate groups from one side of the installation groove 6, making it more convenient for the staff to replace the primary purification filter plate groups and the high purification filter plate groups in the installation box 2 and the replacement box 30, and also allowing the staff to clearly observe whether the installation status of the primary purification filter plate groups and the high purification filter plate groups in the installation box 2 and the replacement box 30 are skewed or the installation position is incorrect.

[0037] Although the setting of the protection assembly makes it very convenient for the staff to replace the primary purification filter plate group and the high purification filter plate group, when the staff rotates both protection plates 5 to a state where they do not abut the bottom surface of the installation box 2, the staff may not pay attention, causing the installation box 2 to fall directly after losing the restriction of the protection plates 5. In order to solve this technical problem, refer to Figure 6 The setting of the bearing assembly 7 in this embodiment solves this technical problem. When the staff rotates all the two protective plates 5 to a state where they do not abut the bottom surface of the installation box 2, the supporting bending springs 71 support the replacement box 30 against the supporting plates 70 to prevent the installation box 2 from falling with the replacement box 30, and the supported replacement box 30 will also pull the installation box 2 to prevent the installation box 2 from falling. At this time, after the staff stabilizes the installation box 2, they pull the installation box 2 downward to make the bottom surface of the replacement box 30 press the supporting plates 70 to rotate and compress the supporting bending springs 71, so that the replacement box 30 can fall into the chassis 1, and then the two protective plates 5 are rotated to abut the bottom surface of the replacement box 30, completing the replacement of the primary purification filter plate group and the high purification filter plate, making it safer for the staff to replace the primary purification filter plate group and the high purification filter plate.

[0038] In this embodiment, connecting pieces 4 are fixedly provided on both the upper and lower surfaces of the bottom surface of the replacement box 30 and both the upper and lower surfaces of the bottom surface of the installation box 2, so that after the staff removes the installation box 2 from the replacement box 30 and replaces the primary purification filter plate group and the high purification filter plate group in the installation box 2, the installation box 2 can be placed in the spare box 3, and then the connecting piece 4 on the bottom surface of the installation box 2 and the connecting piece 4 on the upper surface of the replacement box 30 are buckled together, so that the installation box 2 and the replacement box 30 can be reused. Each time the primary purification filter plate group and the high purification filter plate group are replaced, the installation box 2 and the replacement box 30 are used, which saves the use cost, and the connecting piece 4 can also be used as a handle, which makes it more convenient for the staff to pull the installation box 2 or the replacement box 30.

[0039] In this embodiment, an opening is provided on one side of the spare box 3 which passes through to the interior of the spare box 3. A baffle 31 is inserted on the upper surface of the spare box 3 to block the opening. By pulling the baffle 31 upwards, the interior of the spare box 3 is exposed, so that the staff can easily install the replacement box 30 and the installation box 2 in the spare box 3.

[0040] In this embodiment, an elastic rubber 32 is fixedly provided on the inner side of the spare box 3 along the opening shape of the spare box 3. When the baffle 31 is pushed to block the opening of the spare box 3, the baffle 31 will press the elastic rubber 32, so that the elastic rubber 32 fills the gap between the baffle 31 and the spare box 3, thereby improving the sealing of the spare box 3.

[0041] In this embodiment, two opposing limit blocks 72 are provided at the front and rear ends of the carrier plate 70, and the distance between the two limit blocks 72 is as wide as the opening of the chassis 1, so that the replacement box 30 is located inside the chassis 1. When the staff needs to reuse the installation box 2, the installation box 2 is placed on the carrier plate 70 so that it is located between the two limit blocks 72, so that the installation box 2 is aligned with the opening of the chassis 1.

[0042] Specific implementation process: when the primary purification filter plate group and the high purification filter plate group need to be replaced, the protective plate 5 is rotated so that the bottom surface of the installation box 2 no longer abuts the protective plate 5, and then the installation box 2 is pulled down through the connecting piece 4 to fall. During the falling process, the installation box 2 pulls the replacement box 30 down into the chassis 1 through the connecting piece 4. When the bottom surface of the replacement box 30 moves to be flush with the bottom surface of the chassis 1, the protective plate 5 is rotated again so that the bottom surface of the replacement box 30 abuts against the replacement box 30, and then the connecting stud 42 is twisted in the direction away from the 7-shaped connecting strip 40, so that the connecting stud 42 is separated from the 7-shaped connecting strip, so that the connecting piece 4 of the replacement box 30 can be separated from the connecting piece 4 of the installation box 2, thereby completing the replacement of the primary purification filter plate group and the high purification filter plate group.

[0043] After disassembling the installation box 2, remove the primary purification filter plate group and the high purification filter plate group in the installation box 2, and then replace them with new primary purification filter plate group and high purification filter plate group, and then move the upper layer with the replaced installation box 2, pull the baffle 31 upwards, and then twist the connector 4 on the bottom of the installation box 2 to disengage its connecting stud 42 from the 7-shaped connecting strip 40, and then place the installation box 2 on the supporting plate 70 between the two limit blocks 72, so that the connector 4 on the bottom of the installation box 2 passes through the connector 4 on the upper surface of the replacement box 30, and then twist the connecting stud 42 of the connector 4 on the bottom of the installation box 2 so that the connector 4 on the bottom of the installation box 2 and the connector 4 on the upper surface of the replacement box 30 are buckled together, thereby completing the recycling of the installation box 2.

[0044] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
