Description

Technical Field

[0001] The utility model relates to the technical field of bipolar membrane electrodialysis equipment, in particular to a bipolar membrane electrodialysis equipment with an auxiliary sampling function. Background Art

[0002] A bipolar membrane is a layered membrane with a cation exchange layer on one side and an anion exchange layer on the other side. The junction between the cation exchange layer and the anion exchange layer is a water layer. Under the action of an external DC electric field, the water in the water layer is split into H+ and OH-, and passes through the cation exchange layer and the anion exchange layer respectively.

[0003] According to a disclosed bipolar membrane electrodialysis equipment (announcement number: CN220131973U), the locking screw in the above application passes through the through hole on the locking block and is connected to the threaded hole. When the locking screw is continuously tightened, the semicircular hole one and the semicircular hole two continuously clamp the auxiliary slide rod, thereby fixing its membrane assembly on the auxiliary slide rod, increasing the stability of the membrane stack pressure.

[0004] However, in actual use, after bipolar membrane dialysis, the dialyzed liquid needs to be sampled and tested. When performing sampling tests, the existing dialysis equipment needs to manually take out the liquid. When sampling some deep liquid storage boxes, it is difficult for the equipment to take out the required amount of liquid. In view of this, we propose a bipolar membrane electrodialysis device with an auxiliary sampling function. Utility Model Content

[0005] The purpose of the utility model is to provide a bipolar membrane electrodialysis device with an auxiliary sampling function to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a bipolar membrane electrodialysis device with an auxiliary sampling function, comprising a base, a control panel fixedly connected to the outer wall of the base, a liquid pump fixedly connected to the outer surface of the base, a transmission tube fixedly connected to the output end of the liquid pump, a sealing valve fixedly connected to the outer wall of the transmission tube, a dialysis plate fixedly connected to the end of the transmission tube away from the liquid pump, a derivation tube fixedly connected to the outer wall of the dialysis plate away from the transmission tube, a dial fixedly connected to the outer wall of the upper end of the transmission tube, and a sampling assembly provided on the outer wall of the derivation tube, the sampling assembly comprising:

[0007] A liquid storage box, wherein the outer wall of the liquid storage box is fixedly connected to the outer wall of the base, the inner wall of the liquid storage box is fitted with a casing, the inner wall of the casing is rotatably connected to a spiral auger, and the axis of the spiral auger is fixedly connected to a transmission rod;

[0008] A fixed block, the fixed block is fixedly connected to the outer wall of the upper end of the housing, the outer wall of the upper end of the transmission rod is fixedly connected to a self-rotating bevel gear, the outer wall of the self-rotating bevel gear is meshed with a transmission bevel gear, the outer wall of the transmission bevel gear is fixedly connected to a ratchet, and the outer wall of the ratchet is affixed to a pawl;

[0009] The turntable is fixedly connected to the outer wall of the ratchet, the inner wall of the fixed block is fixedly connected to the sealing block, and the outer wall of the fixed block is fixedly connected to the water tank.

[0010] Preferably, a dripping assembly is provided inside the fixed block, and the dripping assembly includes a dripping tube, and the dripping tube is fixedly connected to the outer wall of the fixed block. The outer wall of the dripping tube is threadedly connected with a bolt, and the outer wall of the bolt is fixedly connected with a telescopic plate, and the end of the telescopic plate away from the bolt is fixedly connected with a stop block. Twisting the bolt can control the dripping speed of the liquid in the dripping tube.

[0011] Preferably, a connecting rod is provided at the axis of the turntable, and the connecting rod passes through and is rotatably connected to the outer wall of the fixed block. The connecting rod also passes through and is rotatably connected to the axis of the transmission bevel gear and the ratchet. When the turntable is rotated, the transmission bevel gear and the ratchet can be driven to rotate. At this time, the rotation of the transmission bevel gear causes the rotating bevel gear meshing with it to drive the transmission rod to rotate, so that the transmission rod drives the spiral auger to rotate and drive the liquid to rise.

[0012] Preferably, the pawl is rotatably connected to the inner wall of the fixed block, and a torsion spring is provided at the connection between the pawl and the fixed block. The end of the pawl away from the ratchet passes through the outer wall of the fixed block. The torsion spring enables the pawl to better clamp the ratchet to prevent liquid backflow.

[0013] Preferably, the drip tube is fixedly connected to the outer wall of the fixed block in an inclined shape, the block is fitted with the inner wall of the fixed block, and a drip hole is provided on the outer wall of the lower end of the drip tube away from the fixed block. The inclined drip tube allows the liquid to flow down better, and the block can block the drip tube, which can prevent water from flowing out of the drip tube when cleaning the sampling component.

[0014] Preferably, the self-rotating bevel gear and the transmission bevel gear are both located inside the sealing block, and the transmission rod and the connecting rod are both passed through and rotatably connected to the outer wall of the sealing block. The sealing block can prevent liquid from remaining on the self-rotating bevel gear and the transmission bevel gear during sampling and cleaning, thereby affecting the purity of the sampled liquid.

[0016] 1. The bipolar membrane electrodialysis equipment with auxiliary sampling function can rotate the turntable to drive the transmission bevel gear and the ratchet to rotate. At this time, the rotation of the transmission bevel gear causes the self-rotating bevel gear engaged with it to drive the transmission rod to rotate, so that the transmission rod drives the spiral auger to rotate and drive the liquid to rise, so that the sampling component can sample a liquid storage box with a deeper depth. When the sampling is completed, water can be filled in the water tank, so that the water is driven by the spiral auger to clean the sampling component to prevent residual liquid from affecting the next liquid sampling.

[0017] 2. The bipolar membrane electrodialysis device with auxiliary sampling function can rotate the bolt to drive the telescopic plate so that the block can block the opening of the drip tube during sampling, thereby controlling the dripping speed of the liquid in the drip tube and making the sampling of the liquid in the device more accurate.
