Problems solved by technology

[0002] With the rapid economic growth in China, flow batteries are on the rise. Graphite felt is needed in the production of flow batteries. Most of the graphite felt on the market is used for fireproof materials, and its uniformity of liquid flow is poor, so it is easy As a result, the voltage consistency of the single cells in the flow battery stack is poor, which causes the current loss of the flow battery to be faster

Embodiment 1

[0021] Such as Figure 1-Figure 2 As shown, a graphite felt non-uniformity screening device provided by the present invention includes a test stack (1), and the test stack includes two parallel splints (11), and the edges of each splint 11 are uniform Set the tie rod holes, clamp and connect multiple test boards (12) between the two splints (11), the test boards (12) are clamped and fixed between the test boards (12) by the tie rods 14 and the tie rod nuts 15, the tie rods 14 Through the hole of the pull rod, the pull rod nut 15 is threadedly connected to the two ends of the pull rod 14 .

[0022] The test board (12) includes a substrate (51), a graphite felt placement groove (52) is provided at the center of one side of the substrate (51), and a through groove (54) is provided on one side of the substrate (51) , a water inlet diversion groove (56) is provided on one side of the base plate (51), and a plurality of water inlet diversion grooves (56) are provided on the side fa...

Embodiment 2

[0030] Such as Figure 1-4 As shown, on the basis of Example 1, the lower side of the test pile (1) is supported and fixed by the support platform (4). The support platform (4) includes a bottom frame (41), the upper side of the bottom frame (41) supports a fixed plate (43) through a set of support columns (42), and the test stack (1) is fixed on the plate (43) UPPER SIDE. A group of wheels (44) are mounted on the lower side of the bottom frame (41). The support platform (4) is conveniently moved by wheels. The bottom frame (41) is provided with a plurality of threaded holes, and each threaded hole is threadedly connected to a support seat, and the support seat includes a screw 45, which can be threaded in the threaded hole, and the lower end of the screw 45 is fixedly connected to the base 46 On the screw rod 45, a locking nut 47 is also threaded. When the screw rod 45 is adjusted to a suitable height, the screw rod 45 can be locked by the locking nut 47 to prevent the scr...

Abstract

The invention discloses a graphite felt liquid passing non-uniformity screening device. The device comprises a test stack, the test stack comprises two clamping plates which are arranged in parallel;a plurality of test plates are clamped and connected between the two clamping plates; the test plates comprises substrates A graphite felt containing groove is formed in the center of one side of thesubstrate. A through groove is formed in one side of each substrate, a water inlet flow guide groove is formed in one side of each substrate, the water inlet flow guide groove is communicating with agraphite felt containing groove, the water inlet flow guide groove communicates with the through groove through a communication hole, and the through grooves of the multiple test plates jointly forma water inlet channel. The device has the advantages that water flows through graphite felts and performs horizontal projectile motion from the two sides respectively, the liquid passing nonuniformitybetween the graphite felts is verified by measuring the spraying distance, screening is performed, the verification precision is high, and the speed is high.

Description

technical field [0001] The invention relates to the technical field of screening equipment, in particular to a screening device for unevenness of graphite felt passing liquid. Background technique [0002] With the rapid economic growth in China, flow batteries are on the rise. Graphite felt is needed in the production of flow batteries. Most of the graphite felt on the market is used for fireproof materials, and its uniformity of liquid flow is poor, so it is easy As a result, the voltage consistency of the single cells in the flow battery stack is poor, which causes the current loss of the flow battery to be rapid. Contents of the invention [0003] The object of the present invention is to solve the shortcomings in the prior art, and propose a graphite felt non-uniformity screening device. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A graphite felt passing liquid non-uniformity screening devic...
