Description

Technical Field

[0001] This utility model relates to the field of FFU operation testing technology, specifically to an FFU operation testing fixture. Background Technology

[0002] FFU, as a commonly used air purification device, is widely used in cleanrooms, laboratories and other places with high requirements for air cleanliness.

[0003] For example, Chinese patent CN209744587U (A Ceiling-Mounted Air Purifier) ​​describes a device mounted on a ceiling joist. A centrifugal fan at the air inlet draws in indoor air, which then passes through a purification filter to remove dust, formaldehyde, and other harmful substances, maintaining clean indoor air and creating a healthy living environment. This invention mounts the air purifier on the ceiling, saving space and eliminating the need for additional purification equipment, thus improving the quality of life.

[0004] However, during long-term operation, existing FFUs may experience short circuits, poor contact, or even fires due to factors such as heat and wiring connections. Long-term verification is often carried out on the ceiling joists, but this verification method is cumbersome to install and does not allow for immediate handling of problems. Therefore, it does not meet the current needs. To address this, we have proposed an FFU operation verification test rack. Utility Model Content

[0005] The purpose of this utility model is to provide an FFU operation test rack to solve the problems mentioned in the background art. During long-term operation, existing FFUs may experience short circuits, poor contact, or fires due to factors such as heat and wiring connections. Long-term verification is often carried out on the ceiling keel frame, but this verification method is troublesome to install and does not make it easy to deal with problems in a timely manner.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an FFU operation inspection test rack, comprising: a support, an upper protective net being provided at the top of the support, the support including a galvanized square tube and fixed corners, the galvanized square tube and fixed corners being welded and fixed, and multiple galvanized square tubes and fixed corners being provided, a baffle being provided at the back of the support, a filter being provided at the front end of the baffle, and an FFU being provided at the front end of the filter, and multiple baffles, filters and FFUs being provided.

[0007] Preferably, each of the baffles is provided with a lead screw near the corner, and the lead screw is welded and fixed to the baffle, and the baffle is welded and fixed to the galvanized square tube.

[0008] Preferably, the lead screw has a fixing rod at its front end, both ends of the fixing rod have insertion holes, the fixing rod passes through the insertion holes, and the front end of the fixing rod is threaded with a nut.

[0009] Preferably, the FFU has a motor base inside, and the motor base is fixed to the baffle by external screws. A fan is provided at the front end of the motor base, and the fan is fixed to the motor base by external screws.

[0010] Preferably, side guard nets are provided on both sides of the bracket, and a track is provided between the bottom ends of the two side guard nets. Multiple tracks are provided, and wheel grooves are provided on the upper surface of the tracks.

[0011] Preferably, the bracket is provided with sliding doors at both the front and rear ends, and the bottom of the sliding door is provided with a number of moving wheels, which move along the wheel grooves.

[0012] Preferably, the lower surfaces on both sides of the upper protective net are provided with sliding groove plates, and the sliding groove plates are welded and fixed to the upper protective net.

[0013] Preferably, the top of the sliding door is embedded inside the slide plate and moves along the slide plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) This utility model achieves convenient installation of FFU and individual fan controller by welding galvanized square tubes and fixed corners to form a support frame, welding and fixing the upper and side protective nets to the frame, welding and fixing the sliding plate to the upper protective net, welding and fixing the baffle to the screw rod and then welding it to the frame, embedding the sliding door into the sliding plate and cooperating with the track, fixing the filter and FFU to the baffle with a fixed rod and screws, fixing the fan and motor base with screws and connecting it to the baffle with screws. In this way, FFU and individual fan controller can be conveniently installed. Both FFU and filter can be installed for long-term verification and individual fan controller can be verified for long-term verification in the same position, saving space. This solves the problem that in the current FFU, long-term operation may cause short circuits or poor contact, fires, etc. due to heat and wiring connections. Long-term verification is often carried out on the ceiling keel frame. This verification method is troublesome to install and is not easy to deal with in time after problems occur.
