Description

Technical Field

[0001] The invention relates to the field of electrocatalytic technology, and in particular to an electrocatalytic hydrolysis reaction waste liquid treatment device. Background Art

[0002] The catalytic reaction of electrolyzed water generally produces waste liquid. The specific treatment method is to add certain chemical agents to the wastewater to make the heavy metal ions or other harmful substances in the wastewater react with the agents to form insoluble precipitates, thereby separating them from the wastewater. For alkaline wastewater containing heavy metal ions, precipitants such as sodium sulfide and sodium carbonate can be added to make the heavy metal ions form sulfide or carbonate precipitation. Pure sodium sulfide is a colorless crystalline powder, but it is easily oxidized in the air and often appears yellow or pink. Industrial sodium sulfide contains impurities, and its appearance is mostly reddish-brown block or flaky solid.

[0003] When treating waste liquid, treatment agents are generally added to the waste liquid. The traditional direct addition method generally cannot add it evenly, quantitatively and at a uniform speed, which may cause a certain amount of accumulation and affect the chemical reaction process of the waste liquid treatment. In addition, the traditional stirring method will stir the liquid as a whole, causing the water body to shake violently, which can easily throw the chemicals floating on the liquid surface onto the cylinder wall, causing waste. Summary of the invention

[0004] In order to make up for the above deficiencies, the present invention provides an electrocatalytic hydrolysis reaction waste liquid treatment device that overcomes the above technical problems or at least partially solves the above problems.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An electrocatalytic hydrolysis reaction waste liquid treatment device comprises a treatment barrel, a slotted ring is provided on the top of the treatment barrel, a top ring is provided on the top of the slotted ring, a reaction mechanism is provided on the ring body of the top ring, and the reaction mechanism comprises:

[0010] A spreading assembly, the spreading assembly being arranged on the top of the second mounting plate;

[0011] A feeding assembly is arranged on the top of the spreading assembly.

[0012] By setting up a driving component, the driving component can make the spreading component revolve around the center of a circle on the top of the processing barrel. This spreading method can carry out circular spreading instead of pouring it into the same area all at once, which greatly increases the contact area, facilitates dissolution and subsequent chemical reaction processes, and is suitable for common circular reaction barrels on the market. The revolution of the spreading component drives the material to form a circular motion trajectory on the top of the reaction barrel. This movement method can drive the liquid in the barrel to produce a certain circulation, which helps to mix the material and the liquid more fully. Under the action of the circulation, the material can diffuse into the entire reaction system more quickly, avoiding the situation of excessively high or low local concentration, so that the dissolution and chemical reaction are carried out in a more uniform environment, further improving the reaction efficiency.

[0016] In one embodiment of the present invention, a second limiting rotating wheel is provided at the end of the first mounting rod, the second limiting rotating wheel overlaps the top of the top ring, the bottom of the second mounting plate is provided with a second mounting rod located in the inner circle of the top ring, the bottom of the second mounting rod is provided with a bending plate, the side of the bending plate is provided with a third limiting rotating wheel through a movable shaft, and the third limiting rotating wheel overlaps the bottom of the slotted ring.

[0017] In one embodiment of the present invention, the sowing assembly includes a mounting block, a sowing bin is provided on one side of the mounting block, a second drive shaft is movably provided in the mounting block, and a brush located in the sowing bin is provided on the shaft body of the second drive shaft.

[0018] In one embodiment of the present invention, a second servo motor is provided on the other side of the mounting block, and the second servo motor is electrically connected to the battery compartment.

[0019] In one embodiment of the present invention, the feeding assembly includes a flat box, the flat box is provided with a top side of a sowing bin, the bottom of the inner wall of the flat box is provided with a slope strip, the flat box is obliquely arranged, and the inner wall of the flat box is provided with a fan-shaped edge.

[0020] In one embodiment of the present invention, a feeding port is provided on the top of the feeding assembly, and the feeding port is fixedly provided on the top of the flat box. A drawer is movably inserted into the top plate of the flat box, and the bottom of the feeding port is connected to the top of the flat box.

[0021] In one embodiment of the present invention, a processing mechanism is provided inside the cylinder body of the processing barrel, and the processing mechanism includes a hexagonal shaft, a driving disk connected to one side of the bottom of the sowing bin is provided on the top of the hexagonal shaft, the hexagonal shaft is movably plugged into the bottom of the inner wall of the cylinder body of the processing barrel, a hexagonal slot block is movably sleeved on the shaft body of the hexagonal shaft, a third mounting rod is installed around the hexagonal slot block, a float is provided at the end of the third mounting rod, and an inclined frame is provided on one side of the float through a connecting rod.

[0022] The present invention provides an electrocatalytic hydrolysis reaction waste liquid treatment device, and its beneficial effects include:

[0023] 1. By setting a driving component, the driving component can make the spreading component revolve around the center of the circle on the top of the processing barrel. This spreading method can be used for circular spreading instead of one-time pouring in the same area, which greatly increases the contact area, is conducive to dissolution and subsequent chemical reaction processes, and is suitable for common circular reaction barrels on the market. The revolution of the spreading component drives the material to form a circular motion trajectory on the top of the reaction barrel. This movement can drive the liquid in the barrel to produce a certain circulation, which helps to mix the material and the liquid more fully. Under the action of the circulation, the material can diffuse faster into the entire reaction system, avoiding the situation of excessively high or low local concentration, so that the dissolution and chemical reaction are carried out in a more uniform environment, further improving the reaction efficiency.

[0024] 2. By setting up the feeding component, the fan-shaped edges can evenly spread the chemical reagents, rather than simply pouring them in at one time. Pouring the reagents in one go may cause an instantaneous violent reaction, posing a safety hazard. Evenly spreading the reagents can make the reaction proceed smoothly and reduce the intensity of the reaction. Evenly spreading the acid can make the reaction proceed gently and reduce the occurrence of safety accidents.

[0025] 3. By setting up the treatment mechanism, the inclined frame of the treatment mechanism is always located at the top of the liquid surface under the action of the float, which is convenient for direct stirring of the chemical reagents that have been spread on the waste liquid but have not dissolved in time on the liquid surface. The traditional stirring method causes the water body to shake violently, and it is easy to throw the chemical reagents floating on the liquid surface onto the cylinder wall. The inclined frame directly stirs at the top of the liquid surface, and the stirring force is relatively mild and concentrated on the liquid surface, which can effectively reduce the situation where the reagents are thrown onto the cylinder wall due to violent shaking, so that the reagents can be fully used for the reaction, thereby improving the utilization rate of the reagents.

When in use, the crushed chemical treatment reagent is put into the feeding port 4054, and then at the same time The first servo motor 4021 and the second servo motor 4042 are driven to extract the drawer plate 4055 at the same time, and the chemical reagent evenly spreads the chemical reagent. At this time, the second drive shaft 4044 slowly rotates the brush 4045 to evenly drop the chemical reagent. At the same time, the first servo motor 4021 drives the drive gear 4024 through the first drive shaft 4023. Under the meshing action, the drive gear 4024 moves relative to the slotted ring 2, so that the reaction mechanism 4 moves around the center of the barrel body of the treatment barrel 1. Revolution, combined with the spreading action in the previous step, in summary, the chemical agent is spread in a circular shape when it falls on the waste liquid. When the waste liquid is added later, the liquid level will rise. At this time, the treatment mechanism 5 will rise under the action of the float 505. The inclined frame 506 of the treatment mechanism 5 is always located at the top of the liquid surface under the action of the float 505. When one end of the spreading bin 4043 rotates around the other end, the driving disk 502 will be rotated, so that the hexagonal shaft 501 drives the hexagonal slot block 503 to rotate, and finally the inclined frame 506 will whisk and stir the liquid surface.

By setting the drive component 402, the drive component 402 can make the spreading component 404 revolve around the center of a circle on the top of the processing barrel 1. This spreading method can be used for circular spreading, rather than a one-time pouring into the same area, which greatly increases the contact area, is conducive to dissolution and subsequent chemical reaction processes, and is suitable for common circular reaction barrels on the market. The revolution of the spreading component drives the material to form a circular motion trajectory on the top of the reaction barrel. This motion mode can drive the liquid in the barrel to produce a certain circulation, which helps to mix the material and the liquid more fully. Under the action of the circulation, the material can diffuse faster into the entire reaction system, avoiding the situation where the local concentration is too high or too low, so that the dissolution and chemical reaction are carried out in a more uniform environment, further improving the reaction efficiency.

[0049] Specifically, the working process or working principle of the electrocatalytic hydrolysis reaction waste liquid treatment equipment is as follows: when in use, the crushed chemical treatment reagent is put into the feeding port 4054, and then the first servo motor 4021 and the second servo motor 4042 are driven at the same time, and the draw plate 4055 is extracted at the same time, and the chemical reagent evenly spreads the chemical reagent put in.

Combined with the spreading action in the previous step, in summary, the chemical agent is spread in a circular shape when it falls on the waste liquid. When the waste liquid is added later, the liquid level will rise. At this time, the treatment mechanism 5 will rise under the action of the float 505. The oblique frame 506 of the treatment mechanism 5 is always located at the top of the liquid surface under the action of the float 505. When one end of the spreading bin 4043 rotates around the other end, the driving disk 502 will rotate, so that the hexagonal shaft 501 drives the hexagonal slot block 503 to rotate, and finally the oblique frame 506 stirs the liquid surface.
