Description
Technical Field
[0001] This utility model relates to the field of catalyst production, and more specifically, to a catalyst activation liquid concentration device. Background Technology
[0002] A three-way catalytic converter is a precious metal chemical agent used to clean the three-way catalytic converter in vehicles. It is usually made of precious metals such as platinum (Pt), palladium (Pd), and rhodium (Rh). Catalyst activation solution is a specially formulated chemical solution whose core function is to convert the catalyst into a solution with high catalytic activity. In order to reduce transportation, storage and processing costs, the catalyst activation solution needs to be concentrated. This not only obtains a higher concentration of catalyst activation solution and achieves the required chemical state and physical structure more quickly, but also reduces resource waste, logistics costs and leakage risks.
[0003] However, in existing catalyst activation liquid concentration devices, the activation liquid is mixed by central stirring. This stirring method creates dead zones during the catalyst activation liquid concentration process, which easily leads to uneven mixing of materials, low heat transfer efficiency, and consequently, a reduction in the quality of the activated liquid concentration. At the same time, it cannot effectively guide water vapor, which may cause water vapor to stagnate or backflow.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0005] In view of the problems in the related technologies, this utility model proposes a catalyst activation liquid concentration device to overcome the above-mentioned technical problems existing in the existing related technologies.
[0006] Therefore, the specific technical solution adopted by this utility model is as follows: A catalyst activation liquid concentration device includes a concentration tank; a control panel located at the center of the outer side of the concentration tank; a feed pipe located at the top of the outer side of the concentration tank; a discharge pipe located at the bottom of the outer side of the concentration tank; a collection mechanism located at the top of the concentration tank to collect water vapor generated during the concentration of the activation liquid; and a stirring assembly located inside the concentration tank to fully stir the activation liquid.
[0007] Furthermore, in order to collect the water vapor generated during concentration, the collection mechanism includes a sealing cap at the top of the concentration tank, a sealing ring between the bottom of the sealing cap and the top of the concentration tank, a guide cavity in the middle of the top of the sealing cap, and a connecting pipe at the top of the sealing cap and above the guide cavity; a condensation component is provided at the bottom of one end of the connecting pipe.
[0008] Furthermore, in order to collect water vapor, the condensation assembly includes a condenser located at the bottom of one end of the connecting pipe, a condensing pipe located at the top of the condenser and outside the connecting pipe, a collection pipe located at the bottom of the condenser, and a collection bucket located at the bottom of the collection pipe.
[0009] Furthermore, in order to achieve rapid flow of water vapor, an inflow chamber, a pressurization port, and a diffusion chamber are sequentially arranged inside the middle of the connecting pipe.
[0010] Furthermore, in order to achieve the stirring of the concentrated raw material, the stirring assembly includes a connecting strip set on the inner wall of the concentration tank, a fixing rod set at the middle of the bottom end of the connecting strip, a rotating cylinder sleeved on the outside of the fixing rod, and a motor set through the bottom end of the rotating cylinder through the concentration tank.
[0011] Furthermore, to ensure thorough mixing of the concentrate, several first gears are provided on the outer side of the fixed rod, and second gears that mesh with the first gears are symmetrically arranged on the outer side of the first gears. Each second gear has a rotating shaft at one end, and a stirring blade is provided at one end of the rotating shaft.
[0012] Furthermore, in order to guide the water vapor upwards, the guiding cavity is a frustum shape that is narrow at the top and wide at the bottom.
[0013] Furthermore, in order to achieve sufficient division of the concentrate, several cutting blocks are provided on the side of the stirring blade.
[0014] The beneficial effects of this utility model are as follows: (1) Through the collection mechanism, all the water vapor generated in the concentration tank can be collected efficiently and actively, avoiding water vapor from being disorderly retained or dissipated at the top of the tank, thereby reducing production costs. Through the stirring component, the activation liquid raw material can be fully and evenly stirred, avoiding local uneven concentration or particle sedimentation, making the activation liquid raw material more evenly heated, and improving the quality of the finished product of the concentrate.
[0015] (2) Under the action of the guiding cavity, the water vapor is gathered and guided, and smoothly guided to the connecting pipe. Under the action of the inflow cavity, the pressurization port and the diffusion cavity, the water vapor is accelerated by itself, avoiding the water vapor from being stuck or condensing prematurely in the long connecting pipe.
[0016] (3) The raw materials of the activation liquid are fully rotated and stirred by the stirring blade and the cutting block. At the same time, the cutting block is used to shear and cut the small agglomerated particles at high speed to avoid local uneven concentration or particle sedimentation, so that the raw materials of the activation liquid are heated more evenly and the quality of the finished product of the concentrate is improved.

[0020] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.
[0021] According to an embodiment of the present invention, a catalyst activation liquid concentration device is provided.
[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-4As shown, the catalyst activation liquid concentration device according to an embodiment of the present invention includes a concentration tank 1; a control panel 2, disposed in the middle of the outer side of the concentration tank 1; a feed pipe 3, disposed at the top of the outer side of the concentration tank 1; a discharge pipe 4, disposed at the bottom of the outer side of the concentration tank 1; a collection mechanism 5, disposed at the top of the concentration tank 1, for collecting water vapor generated during the concentration of the activation liquid; and a stirring assembly 6, disposed inside the concentration tank 1, for fully stirring the activation liquid.
[0023] With the help of the above technical solution, the collection mechanism 5 plays a key role in gathering and guiding water vapor under the action of the guiding cavity. It actively and efficiently collects all the water vapor generated in the concentration tank and smoothly guides it to the connecting pipe. This avoids the disorderly retention or dissipation of water vapor at the top of the tank, which not only saves water resources but also prevents the escape of steam containing trace amounts of catalyst components, thereby reducing production costs. The stirring component 6 can not only fully rotate and stir the activation liquid raw material, but also use the cutting block to perform high-speed shearing and cutting of the activation liquid raw material and any small agglomerates that may exist in it, ensuring that the activation liquid can be fully and uniformly stirred, avoiding local uneven concentration or particle sedimentation, making the activation liquid raw material more uniformly heated, and improving the quality of the finished product of the concentrate.
[0024] In addition, in specific implementation, an electric heating wire is installed inside the shell of the concentration tank 1 to realize the heating function. At the same time, the condenser 5041 and the motor 605 are electrically connected to the control panel 2. The start command is issued through the human-machine interface (HMI) of the control panel 2. This signal is transmitted from the HMI to the PLC programmable logic controller. After receiving the command, the PLC controls the condenser 5041 and the motor 605 to rotate and operate synchronously according to preset data, making precise operations during the concentration of the catalyst activation liquid and ensuring that all operations are carried out accurately. This is existing technology and will not be elaborated on here.
[0025] In one embodiment, the collection mechanism 5 includes a sealing cap 501 at the top of the concentration tank 1, a sealing ring 502 between the bottom of the sealing cap 501 and the top of the concentration tank 1, a guide cavity 505 in the middle of the top of the sealing cap 501, and a connecting pipe 503 at the top of the sealing cap 501 and above the guide cavity 505; a condensing assembly 504 is provided at the bottom of one end of the connecting pipe 503. The condensing assembly 504 includes a condenser 5041 at the bottom of one end of the connecting pipe 503, a condensing pipe 5042 at the top of the condenser 5041 and outside the connecting pipe 503; a collection pipe 5043 at the bottom of the condenser 5041, and a collection tank 5044 at the bottom of the collection pipe 5043. The connecting pipe 503 has an inflow chamber 5031, a pressurization port 5032, and a diffusion chamber 5033 arranged sequentially inside. The guide chamber 505 is a frustum shape that is narrow at the top and wide at the bottom, which enables the efficient collection of all water vapor generated in the concentration tank and its smooth guidance to the connecting pipe. This avoids water vapor from stagnating or dissipating disorderly at the top of the tank, thus saving water resources.
[0026] It should be further explained that the working principle of condenser 5041 is as follows: condenser 5041 circulates cooling water through condenser tube 5042 to connecting tube 503. According to thermodynamics, heat will spontaneously transfer from the high-temperature object to the low-temperature object, thus transferring the heat of water vapor in connecting tube 503 to condenser tube 5042. The kinetic energy of water vapor molecules in connecting tube 503 weakens, resulting in a phase change phenomenon, condensing from a gaseous state to a liquid state. The continuously circulating cooling water will then carry the heat from condenser tube 5042 into the condenser. This is existing technology and will not be elaborated further.
[0027] The working principle of the collecting mechanism 5 is as follows: First, before the concentration operation, the operator puts on the sealing cover 501 to seal the sealing cover 501 and the concentration tank 1. Then, the concentration tank 1 is heated through the control panel 2, and then the stirring component 6 is started. At this time, the three-way catalyst concentrate is continuously heated and evaporates. Then, the water vapor continuously escapes upward. Under the guidance of the guide cavity 505 (narrow at the top and wide at the bottom), the water vapor gathers upward and finally flows into the connecting pipe 503 at the top middle of the sealing cover 501. When flowing inside the connecting pipe 503, the water vapor is gradually contracted when passing through the inflow cavity 5031, the flow rate begins to increase, and the pressure decreases. Then, the water vapor with increased flow rate enters the pressurization port 5032. At this time, the flow rate of the water vapor increases to the maximum value and the pressure is at the minimum. When the water vapor leaves the pressurization port 5032 and passes through the diffusion cavity 5033, the flow rate slows down and the pressure begins to rise again (Bernoulli's principle is used here).
[0028] When water vapor passes through the condenser tube 5042, the high-temperature water vapor is cooled by the action of the condenser 5041 and the condenser tube 5042, and the cooled liquid water is stored in the collection tank 5044 through the collection tube 5043.
[0029] In one embodiment, the stirring assembly 6 includes a connecting strip 601 disposed on the inner wall of the concentration tank 1. A fixing rod 603 is disposed at the middle of the bottom end of the connecting strip. A rotating cylinder 604 is sleeved on the outer side of the fixing rod 603. A motor 605 is disposed through the bottom end of the rotating cylinder 604 and passes through the concentration tank 1. A plurality of first gears 606 are disposed on the outer side of the fixing rod 603, and second gears 607 that mesh with the first gears 606 are symmetrically disposed on the outer side of the first gears 606. A rotating shaft 608 is disposed at one end of each of the second gears 607, and a stirring blade 609 is disposed at one end of the rotating shaft 608. A plurality of cutting blocks 610 are disposed on the side of the stirring blade 609.
[0030] It should be noted that, in application, the fixed rod 603 is connected to the rotating cylinder 604, the rotating shaft 608 is connected to the rotating cylinder 604, and the rotating cylinder 604 is connected to the motor 605 through sealed bearings, and electromagnetic valves are installed at the connection points of the feed pipe 3 and the discharge pipe 4 with the concentration tank 1.
[0031] The working principle of the stirring assembly 6 is as follows: First, the operator starts the motor 605 through the control panel 2. The motor 605, upon receiving the start signal, drives the rotating drum 604 to rotate. Under the rotation of the rotating drum 604, the second gear 607 rotates around the fixed rod 603. At this time, since the first gear 606 and the second gear 607 mesh with each other, the second gear 607 drives the stirring blade 609 to rotate, thereby realizing the revolution and rotation of the stirring blade 609 around the fixed rod 603.
[0032] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.
[0033] In practical applications, firstly, the operator pours the catalyst activation liquid raw material (for three-way catalysts, this is typically an aqueous solution containing precious metals such as platinum, palladium, and rhodium) into the concentration tank 1 through the feed pipe 3. Then, the solenoid valves of the feed pipe 3 and the discharge pipe 4 are closed, and the sealing cap 501 is tightened to ensure airtightness during concentration. Next, the concentration tank 1 is started to heat the activation liquid (for three-way catalysts, the temperature is controlled between 60°C and 90°C). Then, the stirring assembly 6 is started to stir the activation liquid, ensuring that the raw material is heated more evenly and thoroughly (for three-way catalysts, the stirring time can be selected to be 20 to 30 minutes). Driven by the motor 605, the stirring blades 609 are driven to thoroughly stir the activation liquid raw material, and the flow is... The activated liquid raw material is further cut by the cutting block 610 (the working principle of the stirring component 6 is as described above). When the activated liquid raw material is heated, it continuously generates water vapor, which flows upward. Under the guidance of the guiding chamber 505, the water vapor flows through the connecting pipe 503 to the condenser pipe 5042 (the working principle of the collection mechanism 5 is as described above). Finally, it is cooled into liquid water and stored and reused through the collection tank 5044. After the concentration operation is completed, the operator sends a stop command to the motor 605 and the condenser 5041 through the control panel 2, and opens the solenoid valve at the discharge pipe 4 to collect the concentrated catalyst activated liquid. The sealing cover 501 is then opened, and the inside of the concentration tank 1 is cleaned by high-pressure spraying.
[0034] In summary, by utilizing the above-mentioned technical solution of this utility model, the collecting mechanism 5, under the action of the guiding cavity 505, plays a crucial role in gathering and guiding water vapor, actively and efficiently collecting all the water vapor generated in the concentration tank 1 and smoothly guiding it to the connecting pipe 503. This avoids the disorderly retention or dissipation of water vapor at the top of the tank, saving water resources and preventing the escape of steam containing trace amounts of catalyst components, thereby reducing production costs. Through the stirring component 6, the activation liquid raw material can be fully rotated and stirred, and the cutting block 610 can be used to shear and cut the activation liquid raw material and any small agglomerates that may exist in it at high speed, ensuring that the activation liquid raw material (such as precious metal components such as platinum, palladium, and rhodium) can be fully and uniformly stirred, avoiding local uneven concentration or particle sedimentation, making the activation liquid raw material more evenly heated, and improving the quality of the concentrated product.
