Description

Technical Field

[0001] This utility model relates to the field of electrochemistry and materials preparation technology, specifically to an electrochemical catalytic selenium electrolysis device. Background Technology

[0002] An electrochemical catalytic selenium electrolysis device is a specialized apparatus that drives a directed redox reaction of selenium and its compounds using electrochemical catalysis technology. Its core principle is to reduce the overpotential of the selenium ion electrolysis reaction using a catalytic electrode, combined with an optimized device structure to promote mass transfer and reaction regulation, thereby achieving efficient conversion of selenium.

[0003] Currently, there are various technologies for electrochemical catalysis of selenium. The design of the electrolyte inlet and outlet directly affects the flow state, concentration distribution, and device stability of the electrolyte. Existing technologies include straight pipe inlets and distribution pipe inlets. Among them, the flow rate of the straight pipe inlet is controlled by a valve, but occasionally the flow rate may be too high, which will directly impact the electrode surface and cause the electrolyte to form a turbulent zone on the electrode surface. The valve cannot handle the sudden problem in time, which affects the mass transfer efficiency. Therefore, there is a need to provide an electrochemical catalytic selenium electrolysis device. Utility Model Content

[0004] The purpose of this invention is to provide an electrochemical catalytic selenium electrolysis device to solve the problems mentioned in the background section. To solve these technical problems, this invention is achieved through the following technical solution:

[0005] This utility model relates to an electrochemical catalytic selenium electrolysis device, comprising:

[0006] An electrolytic cell, wherein an electrolyte inlet is provided at the top of one end and an electrolyte outlet is provided at the bottom of the other end;

[0007] The current limiting component includes a connecting ring fixed to the electrolyte inlet, through holes around the connecting ring, a memory spring passing through the through holes, fixing rings fixed to both ends of the memory spring, a push plate fixed to one end of the fixing ring, a push block fixed to the other end of the fixing ring, and a baffle plate abutting against one end of the push block.

[0008] Furthermore, the current limiting component also includes a sliding track fixed inside the electrolyte inlet, a slider disposed at the bottom center of the sliding track, and the pushing block fixed at the bottom of the slider.

[0009] Furthermore, the flow limiting component also includes a support ring penetrating both ends of the baffle plate and a fixing block fixed inside the electrolyte inlet, with the other end of the fixing block fixed to the support ring.

[0010] Furthermore, the flow limiting component also includes several holes on the baffle plate, which are evenly distributed on the baffle plate. The baffle plate is L-shaped, with its short side abutting against one end of the push block and its long side having holes.

[0011] Furthermore, the current limiting component also includes a protective sleeve fitted over the memory spring and a fixing post fixed inside the fixing ring, with the memory spring fitted over the outside of the fixing post.

[0012] Furthermore, it also includes a twisting component, which includes a torsion spring fitted onto one end of the support ring and a square locking block fixed to the support ring, with both ends of the torsion spring fixed to the baffle plate.

[0013] Furthermore, the support ring is fitted into the baffle plate, and the torsion spring is sleeved on the support ring.

[0014] This invention has the following beneficial effects: When the liquid flow rate at the electrolyte inlet begins to increase, it begins to push the push plate, which in turn compresses the memory spring. When the memory spring reaches a critical value, it pushes the push block backward, causing the slider to slide on the sliding track. The push block drives the baffle plate to rotate, and the baffle plate rotates along the support ring. The baffle plate changes direction according to the size of the water flow. The greater the speed of the water flow, the more perpendicular the angle of the baffle plate is to the direction of the water flow, thus creating a greater obstruction to the water flow.

[0015] This invention, through the design of a flow-limiting component, enables the internal components to react immediately when the water flow at the straight pipe inlet changes, preventing significant damage to the components inside the electrolytic cell due to unnoticed by staff, thus reducing unnecessary losses and minimizing manpower and material resources.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-5 As shown, this utility model is an electrochemical catalytic selenium electrolysis device, comprising:

[0027] Electrolytic cell 10, with an electrolyte inlet 11 at one end and an electrolyte outlet 12 at the other end.

[0028] The current limiting component includes a connecting ring 20 fixed to the electrolyte inlet 11, a through hole 21 around the connecting ring 20, a memory spring 22 passing through the through hole 21, a fixing ring 23 fixed to both ends of the memory spring 22, a push plate 24 fixed to one end of the fixing ring 23, a push block 25 fixed to the other end of the fixing ring 23, and a baffle plate 26 abutting against one end of the push block 25.

[0029] Electrolytic cell 10 contains the electrolyte and provides a site for the electrolytic reaction; it must be made of a selenium-resistant material. Electrolyte inlet 11 delivers the selenium solution to be electrolyzed and is usually connected to a storage tank or circulating pump. Connecting ring 20 fixes the flow-limiting component to electrolyte inlet 11. Through hole 21 allows memory spring 22 to pass through and guides the spring's extension and contraction direction. When the liquid flow rate is too high, memory spring 22 is compressed, pushing the flow-limiting action, reducing the flow rate, and the flow-limiting component no longer functions. Fixing ring 23 clamps both ends of memory spring 22, transmitting the spring extension and contraction force to push plate 24 and push block 25. Push plate 24 converts the liquid's impact force into spring force. Push block 25 connects to slider 28 and pushes baffle 26 to rotate; it must have sufficient rigidity. Baffle 26 changes the flow area by moving, thus achieving flow restriction.

[0030] The current limiting component also includes a sliding track 27 fixed inside the electrolyte inlet 11 and a slider 28 disposed in the middle of the bottom end of the sliding track 27, wherein the pushing block 25 is fixed at the bottom end of the slider 28;

[0031] The sliding track 27 and the slider 28 constrain the movement trajectory of the push block 25, thereby driving the baffle 26.

[0032] The flow limiting component also includes a support ring 29 penetrating both ends of the baffle plate 26 and a fixing block 291 fixed inside the electrolyte inlet 11, with the other end of the fixing block 291 fixed to the support ring 29;

[0033] The support ring 29 and the fixing block 291 support the rotation axis of the baffle 26 and maintain structural stability.

[0034] The flow limiting component also includes holes 261 on the baffle plate 26. There are several holes 261, which are evenly distributed on the baffle plate 26. The baffle plate 26 is L-shaped, with its short side abutting against one end of the push block 25 and its long side having holes 261.

[0035] The L-shaped design combines structural strength with flow regulation, and the 261 orifice is used to disperse the liquid flow and prevent clogging.

[0036] The current limiting component also includes a protective sleeve 221 fitted outside the memory spring 22 and a fixing post 222 fixed inside the fixing ring 23, wherein the memory spring 22 is fitted outside the fixing post 222;

[0037] The protective sleeve 221 isolates the memory spring 22 from the electrolyte, preventing corrosion and extending service life; the fixing post 222 is fitted with the memory spring 22 to prevent the spring from shifting radially and ensure accurate extension and contraction.

[0038] Working principle: When the liquid flow rate at the electrolyte inlet 11 begins to increase, it starts to push the push plate 24. The push plate 24 drives the memory spring 22 to compress. When the memory spring 22 reaches the critical value, it pushes the push block 25 backward. The slider 28 slides on the sliding track 27. The push block 25 drives the baffle plate 26 to rotate. The baffle plate 26 rotates along the support ring 29. The baffle plate 26 changes direction with the size of the water flow. The greater the speed of the water flow, the more perpendicular the angle of the baffle plate 26 is to the direction of the water flow, and the greater the obstruction to the water flow.

[0039] This solution, through the setting of flow-limiting components, enables the internal components to react immediately when the water flow at the straight pipe inlet changes, thus preventing significant damage to the components inside the electrolysis cell 10 due to unnoticed by staff, reducing unnecessary losses, and saving manpower and resources.

[0040] Furthermore, after the push block 25 in the flow-limiting component retracts, the baffle 26, having nothing to hold it back, will sag due to gravity, hindering the normal liquid flow rate and reducing it, leading to the accumulation of solids in the liquid. This problem is solved by a designed twisting mechanism.

[0041] Specifically, it also includes a twisting component, which includes a torsion spring 30 sleeved on one end of the support ring 29 and a square locking block 31 fixed on the support ring 29. The two ends of the torsion spring 30 are fixed on the baffle plate 26.

[0042] The torsion spring 30 provides restoring torque, which drives the baffle 26 to reset when the flow rate decreases. The preload should be moderate. The torsion spring 30 is made of corrosion-resistant material. The square locking block 31 fixes the two ends of the torsion spring 30 to ensure that the torque is effectively transmitted to the baffle 26.

[0043] The support ring 29 is fitted into the baffle 26, and the torsion spring 30 is fitted onto the support ring 29;

[0044] This setting helps limit the position of torsion spring 30.

[0045] Working principle: When the pusher block 25 pushes the baffle plate 26 to rotate, the flow rate slows down, but the baffle plate 26 still obstructs the flow of liquid. Therefore, the torsion spring 30 fixed on the baffle plate 26 can rotate the baffle plate 26 with the pusher block 25 when it returns, so that the baffle plate 26 can open and close according to the size of the water flow. When the liquid flow rate is insufficient to push the pusher plate 24, the baffle plate 26 is brought back to a position parallel to the liquid by the torsion spring 30, without affecting the normal flow of the liquid. At the same time, the square locking block can fix the position of the torsion spring 30 to prevent the torsion spring 30 from being misaligned.

[0046] This design uses a torsion spring 30 to allow the baffle 26 to adjust the amount of liquid it blocks, and after being perpendicular to the liquid, it can automatically rotate back to a state parallel to the liquid.

[0047] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
