Description

Technical Field

[0001] The utility model relates to the technical field of ion membrane electrolyzers, in particular to an anode and cathode collecting box for chemical electrolysis. Background Art

[0002] In the ion cell for chemical electrolysis, it is usually necessary to install anode and cathode collection boxes; cathode and cathode collection boxes, as the name implies, are devices used to separate gas and liquid in chemical electrolysis experiments and to recover and collect electrolyte;

[0003] The cathode and anode collecting boxes in the prior art generally include a box body, a long baffle and a short baffle are respectively welded and fixed at the position where the upper end of the box body contacts the L-corner, and a liquid outlet insertion port is provided at the lower end of the position where the long baffle contacts the short baffle; at the same time, holes are drilled at intervals at the position where the lower end of the long baffle contacts the upper surface of the box body by a drilling rig;

[0004] When the cathode and anode collecting box is used, the electrolyte dripping on the upper surface of the box body passes through the drilling position and then is guided to gather at the liquid outlet insertion position; at the same time, the long baffle and the short baffle cooperate to block the dripping electrolyte to prevent the electrolyte from splashing;

[0005] However, when manufacturing the cathode and anode collecting box, the long baffle and the short baffle arranged on the upper end of the box body need to be welded and fixed, rather than being integrally formed with the box body; in addition, the drilling needs to be calibrated using a drill, and the drilling is limited by the narrow space formed by the long and short baffles and the upper end of the box body, which makes the manufacturing of the cathode and anode collecting box more troublesome;

[0006] In view of the problems in the above-mentioned background technology, the utility model aims to provide a cathode and anode collecting box for chemical electrolysis. Utility Model Content

[0007] The purpose of the utility model is to provide a cathode and anode collecting box for chemical electrolysis to solve the problems raised in the above-mentioned background technology.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] A cathode collecting box for chemical electrolysis, the cathode collecting box for chemical electrolysis comprising:

[0010] A box body is formed by one-time processing of a metal material titanium or nickel with the aid of a bending machine; a bending plate formed by one-time bending and pressing of the bending machine is formed on the upper end of one side of the box body, and a positioning protrusion formed by one-time bending and pressing of the bending machine is formed at the end of one end of the box body;

[0011] A thickening plate is installed on one side of the upper end surface of the box body, and a longitudinal strip gap is formed by welding at a position where the thickening plate is installed close to the bending plate on the upper end surface of the box body; a longitudinal mesh plate is welded on the inner side of the strip gap.

[0012] As a further solution of the utility model: one end of the box body is further provided with a liquid outlet insertion port at a position where the locking protrusion is formed, for collecting and discharging the electrolyte flowing through the upper end surface of the box body.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] Compared with the existing anode and cathode collection boxes, the anode and cathode collection boxes for chemical electrolysis have the following advantages:

[0015] 1. The bending plate and the positioning protrusions used to block the splash of electrolyte are formed by one-time processing of the box body by a bending machine, eliminating the process of welding baffles on the original anode and cathode collection box, thereby improving the production and processing efficiency of the entire anode and cathode collection box for chemical electrolysis;

[0016] 2. Compared with the traditional method of punching holes on the upper surface of the box body to form a diversion area in the narrow area between the baffle and the upper end of the box body through a drilling rig, the strip gap is set in cooperation with the mesh plate, so that the electrolyte inflow is larger while no drilling operation is required, saving costs and processing procedures.

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] Example

[0024] See also Figure 1 , Figure 2 and Figure 3 , a cathode and cathode collecting box for chemical electrolysis provided in an embodiment of the utility model, the cathode and cathode collecting box for chemical electrolysis comprises:

[0025] A box body 2, wherein the box body 2 is formed by one-time processing using a metal material of titanium or nickel with the aid of a bending machine; a bending plate 1 is formed at the upper end of one side of the box body 2, and the formed bending plate 1 is used to provide a blocking space to prevent the electrolyte collected by the entire anode and cathode collecting box for chemical electrolysis from splashing during collection, thereby causing loss of the collected electrolyte; at the same time, a positioning protrusion 4 is formed at one end of the box body 2, and the formed positioning protrusion 4 has the same function as the bending plate 1, both of which are to effectively prevent the electrolyte from splashing during collection, thereby causing loss of the electrolyte; at the same time, the formation mechanism of the provided positioning protrusion 4 is the same as that of the bending plate 1, and both are formed by one-time bending and pressing on the box body 2 by a bending machine;

[0026] The box body 2 is also provided with a liquid outlet insertion port 3 at one end thereof where the locking protrusion 4 is formed. The liquid outlet insertion port 3 is used to collect and discharge the electrolyte collected on the upper end surface of the box body 2.

[0027] In the embodiment of the utility model, when the anode and cathode collecting box for chemical electrolysis is used, the electrolyte dripped on the upper surface of the box body 2 flows, and is guided along the upper surface of the box body 2 to the upper position of the liquid outlet insertion port 3, and then is collected and discharged through the installed liquid outlet insertion port 3; after the electrolyte drips on the upper surface of the box body 2, the bending plate 1 provided on one side of the upper end of the box body 2 and the positioning protrusion 4 provided on one side of the upper end of the box body 2 cooperate to form a barrier for the electrolyte dripping on the upper surface of the box body 2, so as to avoid splashing when the electrolyte flows, causing the electrolyte to overflow to the outside of the box body 2, resulting in electrolyte loss;

[0028] The bent plate 1, the box body 2 and the clamping protrusion 4 are formed by a bending machine at one time. Compared with the current anode and cathode collecting box, which uses welding and mortise and tenon structures to assemble the bent plate 1 and the clamping protrusion 4 on the original box body 2, the process is simple, the manufacturing process is reduced, and the production efficiency is improved while reducing manpower and raw materials.

[0029] See also Figure 2 and Figure 3 In one embodiment of the utility model, a thickening plate 7 is installed on one side of the upper end surface of the box body 2, and a longitudinal strip gap 5 is formed on the upper end surface of the box body 2 at a position where the thickening plate 7 is installed close to the bending plate 1; a longitudinal mesh plate 6 is welded to the inner side of the strip gap 5; the installed strip gap 5 and the mesh plate 6 are welded and connected after the box body 2 is bent and formed;

[0030] The thickened plate 7 installed on the upper surface of the box body 2 can smoothly and quickly guide the electrolyte dripping on the upper surface of the box body 2 to the position of the strip gap 5, and then quickly fall along the mesh plate 6 formed at the inner position of the strip gap 5;

[0031] Compared with the conventional method of drilling holes on the upper surface of the box body 2 to form the diversion zone, the strip gap 5 cooperates with the mesh plate 6 to allow a larger amount of electrolyte to flow in without the need for drilling, thus saving costs and processing procedures.

[0032] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
